Confirmed Variant Creutzfeldt-Jakob Disease (variant CJD) Case in Texas
Updated: October 7, 2014
CDC and the Texas Department of State Health Services (DSHS) have completed
the investigation of the recently reported fourth vCJD case in the United
States. It confirmed that the case was in a US citizen born outside the Americas
and indicated that the patient's exposure to the BSE/vCJD agent most likely
occurred before he moved to the United States; the patient had resided in
Kuwait, Russia and Lebanon. The completed investigation did not support the
patient's having had extended travel to European countries, including the United
Kingdom, or travel to Saudi Arabia. The specific overseas country where this
patient’s infection occurred is less clear largely because the investigation did
not definitely link him to a country where other known vCJD cases likely had
been infected.
>>>the patient had resided in Kuwait, Russia and Lebanon.
>>>The completed investigation did not support the patient's
having had extended travel to European countries, including the United Kingdom,
or travel to Saudi Arabia.
NOW we all know why the state of Texas or the CDC did not want to report
this case, because it was a home grown case of nvCJD right here in Texas?...tss

Introduction: During 1996-1997, the US Centers for Disease Control and
Prevention, in collaboration with the American Association of Neuropathologists,
established the National Prion Disease Pathology Surveillance Center (NPDPSC) at
Case Western Reserve University in Cleveland, Ohio. This center provides prion
disease diagnostic services to US physicians and state and local health
departments.
Methods: Cases with brain tissue specimens referred to NPDPSC through 2014
were identified from the NPDPSC database and described according to their
demographics and diagnoses. Cases referred to the center from 2005- 2014 were
further described by test results obtained.
Results: Out of 5,369 suspected prion disease cases referred to NPDPSC
through 2014, 3,144 (58.6%) were diagnosed as having a prion disease. The
remaining cases were found to not have a prion disease based on negative
neuropathologic findings (n=2205) or were inconclusive (n=20). The majority of
the 3,144 prion disease cases were sporadic (89.3%), while 10.2% were familial,
0.3% were iatrogenic, and 0.1 % were variant CJD. The majority of cases (87.1 %)
were _>55 years of age. There was not a significant difference in the
percentages of male (51.8%) and female (48.2%) cases diagnosed with prion
disease at NPDPSC (p=0.06. As expected, the most cases were referred from states
with large populations; 44.0% of cases were referred from the 7 most populous
states where approximately this proportion of the US population resides. From
2005-2014, 2,213 cases were diagnosed with prion disease; all cases had either a
positive Western Blot (92.5%) or immunohistochemistry (98.4%) or both (90.9%).
Of the cases with cerebrospinal fluid (CSF) test results available during the
10-year period, 1,103 of 1,460 (75.5%) had a positive 14-3-3 and 1,141 of 1,300
(87.8%) had elevated total Tau protein. More sensitive tests such as RT QulC are
being validated.
Conclusion: The NPDPSC is a valuable resource for prion disease diagnostic
services, especially given that neuropathologic testing is required for disease
confirmation. Notably, a substantial percentage (41.1 %) of suspected prion
disease cases referred to the center were found to be negative for prion
disease. The large collection of brain tissues is critical for development and
validation of new human prion diagnostic and differentiation methods and further
studies advancing our understanding of prion diseases and other
neurodegenerative conditions.

Epidemiological characteristics of human prion diseases
snip...
CJD surveillance systems have some unique features compared with other
public health surveillance systems. One is that due to a lack of approved
biomarkers for CJDs, specific types of clinical and laboratory approaches are
critical to effectively diagnose and monitor CJDs. The other is that CJD
surveillance systems are primarily dependent on reports from physicians,
especially neurologists and neuropathologists in regional hospitals and medical
centers where first visit for most patients. Thus, the experiences of these
specialists directly determine the quality of the collected specimens, such as
accurate identify the clinical manifestations of CJD or supply the appropriate
specimens to CJD surveillance center. Both aspects seriously impact the
sensitivity of CJD surveillance.

Background. With the emergence of bovine spongiform encephalopathy/variant
Creutzfeldt-Jakob disease (vCJD) in the UK, the Centers for Disease Control and
Prevention began utilizing national mortality data with additional surveillance
mechanisms to monitor US occurrences of human prion disease.
Objectives. To review US prion disease surveillance data.
Methods. We analyzed national mortality data for prion disease deaths (a
surrogate for CJD incidence) among US residents for the 30 year period,
1979–2008, augmenting and extending these data through 2010 with information
from other surveillance mechanisms (e.g., national neuropathology surveillance).
We calculated age-adjusted and age-specific death rates per million persons;
race-specific rates used data available beginning 1981. We age-adjusted death
rates to the standard projected US 2000 population. www.landesbioscience.com
Prion 131
Results. A total of 7,615 deaths during 1979–2008 were identified for an
average annual age-adjusted rate of 0.98 cases per million persons. The highest
rate (1.15) was observed in 1997; the highest number of reported cases was in
2008 (348). By race, the rate (1.06) among whites, who constituted 95% of the
cases, was significantly higher than among blacks (0.40), Asian/Pacific
Islanders (0.63) and American Indians/Alaska Natives (0.42). The rate (4.0)
among persons ≥55 years old was strikingly higher than the rate (0.14) among

Introduction. At 16% of the US population, Hispanics make up the largest
ethnic or racial minority in the country, and this proportion is expected to
increase in the coming decades. The occurrence of Creutzfeldt-Jakob disease
(CJD) among Americans of Hispanic ethnicity has not been widely
investigated.
Methods. Hispanic CJD decedents of any age were identified from the US
national multiple cause-of-death data and other sources for 1997–2008. Relevant
portions of medical records and results from neuropathologic and genetic testing
for Hispanic CJD decedents <55 age="" and="" as="" available.="" div="" obtained="" of="" reviewed="" were="" years="">
Results. During 1997–2008, 160 CJD decedents were identified as being of
Hispanic ethnicity, for an average annual age-adjusted incidence of 0.65 per
million population, an incidence significantly lower than that for non-Hispanics
(RR =0.6; 95% CI 0.5–0.7). While 27 states reported at least one Hispanic
decedent during the time period, almost half (47.5%) of the decedents were
residents of California or Texas, the states with the highest Hispanic
populations. A majority (55.0%) of the decedents were females, but the average
annual age-adjusted incidence was slightly higher for males, although the
difference was not significant. The median age at death was 64 years (range
36-93 years). Thirty-three Hispanic CJD decedents (20.6%) were <55 0.0001="" 0.17="" 12.1="" 21="" 33="" age-specific="" age="" among="" and="" annual="" available="" average="" cases="" cjd="" compared="" confirmation="" decedent="" decedents="" div="" familial="" fatal="" for="" group="" had="" hispanic="" hispanics="" however="" in="" incidence="" including="" insomnia.="" lower="" medical="" neuropathologic="" neuropathology="" non-hispanic="" non-hispanics="" of="" one="" or="" p="" records="" reports="" respectively="" review.="" significantly="" sporadic="" ten="" that="" the="" these="" three="" to="" was="" with="" years="" young="">
Conclusions. Between 1997 and 2008, the reported CJD incidence among
Hispanics in the US was significantly lower than that for non-Hispanics. This
lower incidence may be at least partly due to underreporting of Hispanic
ethnicity relative to surveys and censuses, and further study is warranted.
Analyses of brain tissue remain important, especially considering that
approximately half of the young Hispanic decedents with information available
lacked CJD confirmation.

Despite large exposure to BSE in the UK, less than 180 patients had
developed clinical vCJD by October 2009. This figure was closely anticipated in
2001, thanks to an epidemiological model whose main assumptions was that the
risk of acquiring vCJD was exponentially decreasing during childhood, which was
consistent with the age distribution of vCJD. Further investigation of the
models showed that this decrease of risk during childhood could not be explained
by the age variation of meat consumption, and was likely a consequence of an age
dependent susceptibility to the disease. The more likely explanation for this
strong age-susceptibility relationship during childhood is hormonal.
In this context, we investigated if there was a sex difference in human
vCJD cases, and we used a mouse model to test a first hypothesis on the possible
role of sexual hormones on the risk of prion diseases.
In the 167 vCJD cases reported in the UK as of January 2009, age at onset
was significantly lower in women (two years) than in men after stratification on
birth cohort. In C57/BL6N mice infected with ME-7 scrapie strain, incubation was
shorter in females than in males. The incubation period increased in castrated
male mice after intraperitoneal infection, but not after intracerebral
inoculation. We also observed that androgen receptor deficient mice the
incubation period of prion disease also increased after intraperitoneal
inoculation. In contrast, in ovariectomised or estrogen receptor a defective
female mice, no effect was observed on the incubation period of mouse prion
disease.
These results show that androgens influence the prion diseases incubation
period in a peripheral site.1

Background. Creutzfeldt-Jakob Disease (CJD) is a fatal, transmissible
neurodegenerative disease with sporadic, genetic and acquired forms. In 1998,
Canada launched comprehensive national CJD surveillance to assess the
characteristics of CJD in Canada and its risks to the health of Canadians. This
study describes the broad characteristics of CJD in Canada from 1998–2009.
Methods. Case ascertainment was based on internationally accepted criteria.
Demographic information and risk-factor data were collected by standardized
questionnaire and medical chart review. Poisson regression, descriptive
analysis, and case investigation were employed.
Results. A total of 453 CJD deaths in Canadian residents were registered
from 1998–2009. Four hundred and fifteen (92%) were sporadic (sCJD), 33 (7%)
were genetic and five (1%) were acquired. Average annual sCJD mortality was 1.1
per million population, increasing gradually from 0.9 in 1999 to 1.4 in 2009 (P
= 0.27). All provinces saw average annual mortalities ranging from 1.0 to 1.5 (P
= 0.85), except three territories where population is small (~25,000 to
~45,000), sCJD occurred equally in both genders at 1.1. sCJD was rare under 50
years of age with only 11 cases identified (2.7%). Mortality increased after 50
and peaked at 8 per million in the 70–74 age group. Median age at death was 69
and median duration of illness was 4 months. Genetic TSE accounted for 33
deaths: 19 were GSS (P102L: 5, D202N: 2, P105T: 2, Q217R:1, A117V: 1, unknown
mutation: 8); 13 were familial CJD (E200K: 9, D178N: 2, V203I: 1, V189I:1); one
was FFI (D178N). Median age for genetic TSE was 59 and median duration of
illness was 27 months. For the five acquired cases of CJD, four were associated
with dura mater procedures (3 Lyodura, 1 Tutoplast) and were identified from
1998–2003 in patients aged 14–59. Investigation indicated the infections
possibly occurred from 1981–1992 with incubation times from 10–16 years. One
biochemically and neuropathologically confirmed variant CJD death occurred in
2002 in a person under 40 years old, likely acquired overseas.
Discussion and Conclusion. Characteristics of CJD in Canada are consistent
with those observed in other countries. The increase in sCJD mortality can be at
least partly attributed to increased awareness of CJD among referring
clinicians. The finding of four dura matter associated CJD cases and one
imported vCJD case in Canada demonstrate risks to Canadians from acquired CJD
exist. Continued surveillance for iatrogenic risks and novel forms of CJD is
warranted.
HD.23: Creutzfeldt-Jakob disease among American Indians and Alaska natives
in the United States, 1983–2009
Robert C. Holman, Ryan A. Maddox, Arianne M. Folkema, Arialdi M. Minino,
Ermias D. Belay and Lawrence B. Schonberger CDC; Atlanta, GA, USA
Background/Introduction. Creutzfeldt-Jakob disease (CJD) occurrence among
American Indians and Alaska Natives (AI/ ANs) is of special interest, in part
because of the high prevalence of hunting and venison consumption in this
population. Such behaviors could place AI/ANs at increased risk of prion disease
if chronic wasting disease (CWD) were found to transmit to humans.
Materials and Methods. Death records with CJD as anylisted cause of death
for US residents identified from the national multiple cause-of-death data and
other surveillance mechanisms for 1983 through 2009 were analyzed, and incidence
was calculated by race. Available death certificates and medical records were
collected and examined for AI/AN decedents.
Results. During 1983 through 2009, 15 decedents with CJD as a cause of
death were reported as AI/AN race. The average annual age-adjusted CJD incidence
for AI/ANs was 0.39 per 1,000,000 persons. The rate for whites (1.07) was higher
compared with that for AI/ANs (RR = 2.9, 95% CI = 1.8–4.9) and blacks were
similar (0.41; RR = 1.1, 95% CI = 0.7–1.9). The median age at death was 65 y
(range 39–85 y), similar to those for whites and blacks (68 and 66 y,
respectively); four (27%) AI/ AN decedents were younger than 55 y of age. Most
of the AI/AN decedents were males (60%). Decedents were reported from 13 states;
none resided in the states with the longest known presence of CWD, Colorado,
Wyoming, and Nebraska.
Conclusion. The reported CJD incidence for AI/ANs appears lower than that
for whites and similar to that for blacks, although the CJD incidence for AI/ANs
is likely underestimated due to racial misclassification of AI/ANs. Continued
monitoring of CJD occurrence in this population is important as CWD spreads into
new areas.

Introduction. Creutzfeldt-Jakob disease (CJD) predominantly occurs among
older individuals. To describe the possible impact of changing demographics in
the US population on the occurrence of CJD, we reviewed data from the US census
and from national prion disease surveillance.
Methods. Prion disease decedents were identified from the US national
multiple cause-of-death data and the National Prion Disease Pathology
Surveillance Center database for 2008-2010. Incidence rates were calculated for
decedents ≥65 years and then applied to US census population estimates for 2030
to obtain projections of the number of CJD deaths in that year, assuming no
advances in treatment or prevention of these diseases.
Results. US census data projects that ≥65-year-olds will increase from
13.1% of the population in 2010 to 20.3% in 2030. The CJD incidence rates for
2008-2010 among decedents in the 65-74, 75-84, and 85+ year age groups were, in
cases per million population, 6.5, 7.2, and 3.1, respectively. Applying these
incidence rates to US census projections, in 2030 there may be 461 CJD decedents
≥65 years of age in the United States, an increase of more than 200 cases
compared to the 2008-2010 average for this age group. Of the 461 cases, 251 are
projected to be aged 65-74 years, 182 to be aged 75-84 years, and 28 to be aged
85 years or older.
Conclusions. Unless effective treatments for CJD are developed, the aging
population in the United States will likely result in an increase in CJD cases
due to its higher incidence among older adults. The increase in cases could
impact infection control policies and health care costs, among other
factors.

3National Prion Disease Pathology Surveillan ce Center (NPDPSC); Case Western
Reserve University; Cleveland, OH USA Introduction. Asians and Pacific Islanders
(APIs) comprise approximately 5% of the United States population. The occurrence
of Creutzfeldt-Jakob disease (CJD) and other prion diseases among APIs in the
United States has not been widely investigated.
Materials and Methods. API prion disease decedents were identified from the
United States national multiple cause-of-death data and the National Prion
Disease Pathology Surveillance Center database for 2003–2009. Relevant portions
of medical records and results from neuropathologic and genetic testing for API
prion disease decedents were obtained and reviewed, as available.
Results. During 2003–2009, 60 API prion disease decedents were identified;
34 of these decedents had additional race information available, with 15 API
decedents classified as Filipino (44%), 13 as Japanese (38%), 5 as Chinese (15%)
and 1 as Hawaiian (3%). The average annual age-adjusted incidence was 0.7 per
million population, significantly lower than that for whites (p < 0.001).
Over half (55%) of the API deaths occurred in California or Hawaii, the states
with the highest API populations. The median age at death was 66.5 y (range
40–87 y), similar to that for whites (68 y). Neuropathology reports and/ or
medical records were available for 24 of the decedents; for 20 cases with a
reported disease onset date, the median duration of illness was 4.5 mo (range
1–66 mo). Twenty of 22 decedents (91%) had sporadic CJD, while the remaining 2
decedents (9%) had familial CJD. All 20 decedents with genetic testing results
available were methionine homozygous at codon 129.
Conclusion. For 2003–2009, the reported prion disease incidence among APIs
in the United States was significantly lower than that for whites.
Underreporting of API race may contribute at least partly to this lower
incidence, but genetic factors may influence prion disease susceptibility as
well. Because the API race is heterogeneous, further study of prion diseases
among specific API ethnic groups is warranted.

One reason for this was the _inaccuracy_ in coding of cases correctly
certified as CJD Coding is carried out by staff who are not medically qualified
and it is not surprising that coding errors occur in the processing of large
numbers of certificates. In 1982, 12,000 certificates per week were processed at
the office of population censuses and surveys by 15 coders and 6 checkers
(Alderson et al., 1983). The occurrence of both inter- and intra-observer coding
errors has been described (Curb et al., 1983) and the _inaccuracies_ of BOTH
certification and coding discovered in this study _support_ the introduction of

Diagnosis and Reporting of Creutzfeldt-Jakob Disease
To the Editor: In their Research Letter, Dr Gibbons and colleagues1
reported that the annual US death rate due to Creutzfeldt-Jakob disease (CJD)
has been stable since 1985. These estimates, however, are based only on reported
cases, and do not include misdiagnosed or preclinical cases. It seems to me that
misdiagnosis alone would drastically change these figures. An unknown number of
persons with a diagnosis of Alzheimer disease in fact may have CJD, although
only a small number of these patients receive the postmortem examination
necessary to make this diagnosis. Furthermore, only a few states have made CJD
reportable. Human and animal transmissible spongiform encephalopathies should be
reportable nationwide and internationally.

Terry S. Singeltary, retired (medically) CJD WATCH
I lost my mother to hvCJD (Heidenhain Variant CJD). I would like to comment
on the CDC's attempts to monitor the occurrence of emerging forms of CJD.
Asante, Collinge et al [1] have reported that BSE transmission to the
129-methionine genotype can lead to an alternate phenotype that is
indistinguishable from type 2 PrPSc, the commonest sporadic CJD. However, CJD
and all human TSEs are not reportable nationally. CJD and all human TSEs must be
made reportable in every state and internationally. I hope that the CDC does not
continue to expect us to still believe that the 85%+ of all CJD cases which are
sporadic are all spontaneous, without route/source. We have many TSEs in the USA
in both animal and man. CWD in deer/elk is spreading rapidly and CWD does
transmit to mink, ferret, cattle, and squirrel monkey by intracerebral
inoculation. With the known incubation periods in other TSEs, oral transmission
studies of CWD may take much longer. Every victim/family of CJD/TSEs should be
asked about route and source of this agent. To prolong this will only spread the
agent and needlessly expose others. In light of the findings of Asante and
Collinge et al, there should be drastic measures to safeguard the medical and
surgical arena from sporadic CJDs and all human TSEs. I only ponder how many
sporadic CJDs in the USA are type 2 PrPSc?

OR-10: Variably protease-sensitive prionopathy is transmissible in bank
voles

Zou,3 Pierluigi Gambetti,3 Umberto Agrimi1 1Istituto Superiore di Sanità; Rome,
Italy; 2Dipartimento di Scienze Neurologiche, Università di Bologna; Bologna,
Italy; 3Case Western Reserve University; Cleveland, OH USA
Background. Variably protease-sensitive prionopathy (VPSPr) is a recently
described “sporadic”neurodegenerative disease involving prion protein
aggregation, which has clinical similarities with non-Alzheimer dementias, such
as fronto-temporal dementia. Currently, 30 cases of VPSPr have been reported in
Europe and USA, of which 19 cases were homozygous for valine at codon 129 of the
prion protein (VV), 8 were MV and 3 were MM. A distinctive feature of VPSPr is
the electrophoretic pattern of PrPSc after digestion with proteinase K (PK).
After PK-treatment, PrP from VPSPr forms a ladder-like electrophoretic pattern
similar to that described in GSS cases. The clinical and pathological features
of VPSPr raised the question of the correct classification of VPSPr among prion
diseases or other forms of neurodegenerative disorders. Here we report
preliminary data on the transmissibility and pathological features of VPSPr
cases in bank voles.
Materials and Methods. Seven VPSPr cases were inoculated in two genetic
lines of bank voles, carrying either methionine or isoleucine at codon 109 of
the prion protein (named BvM109 and BvI109, respectively). Among the VPSPr cases
selected, 2 were VV at PrP codon 129, 3 were MV and 2 were MM. Clinical
diagnosis in voles was confirmed by brain pathological assessment and western
blot for PK-resistant PrPSc (PrPres) with mAbs SAF32, SAF84, 12B2 and 9A2.
Results. To date, 2 VPSPr cases (1 MV and 1 MM) gave positive transmission
in BvM109. Overall, 3 voles were positive with survival time between 290 and 588
d post inoculation (d.p.i.). All positive voles accumulated PrPres in the form
of the typical PrP27–30, which was indistinguishable to that previously observed
in BvM109 inoculated with sCJDMM1 cases.
In BvI109, 3 VPSPr cases (2 VV and 1 MM) showed positive transmission until
now. Overall, 5 voles were positive with survival time between 281 and 596
d.p.i.. In contrast to what observed in BvM109, all BvI109 showed a GSS-like
PrPSc electrophoretic pattern, characterized by low molecular weight PrPres.
These PrPres fragments were positive with mAb 9A2 and 12B2, while being negative
with SAF32 and SAF84, suggesting that they are cleaved at both the C-terminus
and the N-terminus. Second passages are in progress from these first successful
transmissions.
Conclusions. Preliminary results from transmission studies in bank voles
strongly support the notion that VPSPr is a transmissible prion disease.
Interestingly, VPSPr undergoes divergent evolution in the two genetic lines of
voles, with sCJD-like features in BvM109 and GSS-like properties in BvI109.
The discovery of previously unrecognized prion diseases in both humans and
animals (i.e., Nor98 in small ruminants) demonstrates that the range of prion
diseases might be wider than expected and raises crucial questions about the
epidemiology and strain properties of these new forms. We are investigating this
latter issue by molecular and biological comparison of VPSPr, GSS and Nor98.

Abstract (provisional)
Background
Sporadic fatal insomnia (sFI) and fatal familial insomnia (FFI) are rare
human prion diseases.
Case presentation
We report a case of a 33-year-old female who died of a prion disease for
whom the diagnosis of sFI or FFI was not considered clinically. Following death
of this patient, an interview with a close family member indicated the patient's
illness included a major change in her sleep pattern, corroborating the reported
autopsy diagnosis of sFI. Genetic tests identified no prion protein (PrP) gene
mutation, but neuropathological examination and molecular study showed
protease-resistant PrP (PrPres) in several brain regions and severe atrophy of
the anterior-ventral and medial-dorsal thalamic nuclei similar to that described
in FFI.
Conclusions
In patients with suspected prion disease, a characteristic change in sleep
pattern can be an important clinical clue for identifying sFI or FFI;
polysomnography (PSG), genetic analysis, and nuclear imaging may aid in
diagnosis.

Case presentation
Clinical findings In February 2007, the Centers for Disease Control and
Prevention (CDC) and the National Prion Disease Pathology Surveillance Center
(NPDPSC) notified the Texas Department of State Health Services (DSHS) of a
32-year-old woman with an 18-month history of progressive neurological symptoms
suggestive of CJD. (Table 1) Based on the medical record and her neurologist,
her illness began in August 2005 with attention deficits and progressive memory
loss. In June 2006, she demonstrated anisocoria and bizarre behavior, including
talking incoherently to herself, and she was then referred to psychiatry. On a
mini-mental state examination, she scored abnormally low in the measure of
attention and calculation and she had reduced ability to repeat the names of
three unrelated objects [14]. Later in 2006 she was described as being in
constant motion, having unfocused hand gestures, and continued difficulty with
ambulation. She was reported as alert, but confused, sad, and having difficulty
with her thought process. Physicians caring for the case patient discussed the
possibility of several diagnoses such as viral encephalopathy, paranoid
schizophrenia, and subacute sclerosing panencephalitis, yet the overall etiology
remained unclear. By February 2007, the patient was unable to ambulate and
became bed-bound. She continued to demonstrate bizarre behavior, inability to
follow commands, and unintelligible speech. The patient expired in June 2007, 22
months after the onset of illness.
Over the course of her illness, she had EEGs, magnetic resonance imaging
(MRI) studies, and cerebrospinal fluid (CSF) tests. The EEG study performed in
July 2006 showed generalized slowing with bilateral periodic lateralized
epileptiform discharges. A second EEG performed two to three weeks later was
unsuccessful due to excessive movements of the patient. In April 2006, an MRI
study was negative for intracranial abnormalities. Another MRI study was
completed in February 2007 and it showed supratentorial parenchymal atrophy with
no other acute intracranial findings. CSF studies performed in March 2007 were
normal, including the amount of the 14-3-3 protein determined.
Because of the age of the patient and the potential for variant or
iatrogenic CJD, in July 2007 an investigator from the DSHS (KMM) interviewed a
family member to obtain additional information about the patient’s travel
history, past medical history, and the symptoms of the present illness. The
patient had a history of travel outside the continental United States to Puerto
Rico during 1995-96 where she had lived approximately one year. Her surgical
history included two back surgeries for internal disc disruption and
degenerative disc disease. An anterior lumbar discectomy with interbody fusion
at L4-5 was performed in November 2000 utilizing cadaver donated bone and in
August 2001 another fusion was performed at L5-S1 utilizing autologous bone. The
donor of cadaver bone was pre-screened minimizing the possibility of iatrogenic
transmission. There was no familial history of progressive neurological disease
or dementia-like illness. The family member also confirmed the clinical history
including the onset in August 2005 of progressive memory loss and, in February
2006, bizarre behavior that included the patient’s sitting in a chair for hours
making noises that progressively got louder.
Following preliminary autopsy results, the NPDPSC requested the DSHS
re-interview the family to ask specifically about the patient’s pattern of
sleep. When questioned about insomnia, the family member recalled that the
patient had experienced disturbed sleep at the time of her disease onset. The
family member also reported that the patient’s sleep pattern progressively
deteriorated throughout her illness. Some nights, for example, the patient did
not sleep. On other nights when she did appear to be sleeping, her sleep was
intermittent. During nights that the patient did not sleep, she would roam the
house at all hours, unable to calm down. By August of 2006, four hours was the
maximum amount of sleep the patient would get in one stretch and at times she
would go two to three days without sleep. Medications were prescribed to help
her sleep but they were not beneficial.
Genetic analysis Sequencing of the PrP gene open reading frame revealed
methionine homozygosity at codon 129, with no pathogenic mutation.

CJD or prion disease 2 CASES McLennan County Texas population 230,213 both
cases in their 40s
2 mysterious cases of disease in McLennan County a rarity, but no cause for
alarm
By Cindy V. Culp Tribune-Herald staff writer
Friday July 9, 2010
Two likely cases of a mysterious, fatal brain disorder have been reported
in McLennan County — a statistical anomaly considering that only one in 1
million people worldwide is affected by the condition in any given year.
Adding to the peculiarity is that the noncontagious disorder belongs to the
same family as Creutzfeldt-Jakob disease.
One of its forms is believed to be triggered by people eating meat from
cattle infected with mad cow disease.
As frightening as that might sound, officials said residents shouldn’t be
alarmed.
One of the local cases definitely is not the type associated with mad cow
disease, and there is no evidence the other one is, either. More importantly,
the disorder cannot be transmitted from person to person, officials said.
“To have potentially two cases this close together is statistically
unusual,” said Dr. Farley Verner, an infectious disease specialist who advises
the Waco-McLennan County Public Health District. “But because of the type of
disorder it is, and because of what we know about how it develops, it’s not a
worrisome coincidence. It’s just a coincidence.”
Because of privacy laws, health officials can release only limited details
about the local cases. Both were reported in May.
The first case involved a 49-year-old man from McGregor, Hammad Akram, the
health district’s epidemiologist, said. The man has since died.
Initial results from an autopsy show he had some type of human prion
disease, a family of diseases involving an abnormal protein.
Creutzfeldt-Jakob disease, or CJD, is the most common type of human prion
disease. The autopsy ruled out CJD, however, Akram said.
The second case involves a Waco woman in her late 40s, Akram said. Her
symptoms point to CJD, but since the only way to confirm the disease is to study
brain tissue after death, that diagnosis is not confirmed, he said.
No apparent link
There is no apparent link between the two local victims, Akram said.
Prion disease usually occurs in people older than age 60.
Doctors give patients a “working diagnosis” of human prion disease based on
certain symptoms, combined with results from a blood test, Farley said.
The symptoms are similar to those of other neurological conditions:
confusion, difficulty remembering recent events, loss of feeling in certain body
parts, balance problems, difficulty walking and muscle jerks and spasms.
If a physician rules out other causes for such symptoms, a blood test can
be done that indicates whether the person has a genetic mutation associated with
human prion disease. The test cannot confirm it, but positive results make the
diagnosis more likely, Verner said.
The name of the disease category comes from a protein called a prion.
People have normal prions, which are concentrated in the brain. But in some
instances, there is abnormal prion protein, which causes normal prions to be
converted to abnormal form.
That destroys brain tissue and is eventually fatal. The process can take
years, but most people die within three months to a year of having symptoms.
There are three main categories of human prion disease — sporadic, familial
and acquired.
Sporadic cases start spontaneously, without a clearly identifiable cause.
They account for about 85 percent of all human prion disease, according to the
National Prion Disease Pathology Surveillance Center.
Familial cases are inherited and are caused by a defect in the prion
protein gene, the center said.
Acquired cases are transmitted by infection, which can occur if a person
receives a transplant infected with prion disease or undergoes surgery where
contaminated instruments are used, according to the center.
Another avenue of infection is when someone eats contaminated beef, the
center said. That’s where the connection to mad cow disease comes in.
Only three cases linked to contaminated beef have been found in the United

thought to have been infected while living overseas.
In Texas, about 120 people died from human prion disease between 2000-08,
according to state data.
Last year, there were 19 probable or confirmed cases of sporadic CJD and
two familial CJD cases statewide.
McLennan County has not had any human prion disease cases in the past
decade, according to state records. Verner said he can only recall two or three

EFSA and the European Centre for Disease Prevention and Control (ECDC)
recently delivered a scientific opinion on any possible epidemiological or
molecular association between TSEs in animals and humans (EFSA Panel on
Biological Hazards (BIOHAZ) and ECDC, 2011). This opinion confirmed Classical
BSE prions as the only TSE agents demonstrated to be zoonotic so far ***but the
possibility that a small proportion of human cases so far classified as
"sporadic" CJD are of zoonotic origin could not be excluded. Moreover,
transmission experiments to non-human primates suggest that some TSE agents in
addition to Classical BSE prions in cattle (namely L-type Atypical BSE,
Classical BSE in sheep, transmissible mink encephalopathy (TME) and chronic
wasting disease (CWD) agents) might have zoonotic potential.

Dietary exposure to bovine spongiform encephalopathy (BSE) contaminated
bovine tissues is considered as the origin of variant Creutzfeldt Jakob (vCJD)
disease in human. To date, BSE agent is the only recognized zoonotic prion.
Despite the variety of Transmissible Spongiform Encephalopathy (TSE) agents that
have been circulating for centuries in farmed ruminants there is no apparent
epidemiological link between exposure to ruminant products and the occurrence of
other form of TSE in human like sporadic Creutzfeldt Jakob Disease (sCJD).
However, the zoonotic potential of the diversity of circulating TSE agents has
never been systematically assessed. The major issue in experimental assessment
of TSEs zoonotic potential lies in the modeling of the ‘species barrier‘, the
biological phenomenon that limits TSE agents’ propagation from a species to
another. In the last decade, mice genetically engineered to express normal forms
of the human prion protein has proved essential in studying human prions
pathogenesis and modeling the capacity of TSEs to cross the human species
barrier.
To assess the zoonotic potential of prions circulating in farmed ruminants,
we study their transmission ability in transgenic mice expressing human PrPC
(HuPrP-Tg). Two lines of mice expressing different forms of the human PrPC
(129Met or 129Val) are used to determine the role of the Met129Val dimorphism in
susceptibility/resistance to the different agents.
These transmission experiments confirm the ability of BSE prions to
propagate in 129M- HuPrP-Tg mice and demonstrate that Met129 homozygotes may be
susceptible to BSE in sheep or goat to a greater degree than the BSE agent in
cattle and that these agents can convey molecular properties and
neuropathological indistinguishable from vCJD. However homozygous 129V mice are
resistant to all tested BSE derived prions independently of the originating
species suggesting a higher transmission barrier for 129V-PrP variant.
Transmission data also revealed that several scrapie prions propagate in
HuPrP-Tg mice with efficiency comparable to that of cattle BSE. While the
efficiency of transmission at primary passage was low, subsequent passages
resulted in a highly virulent prion disease in both Met129 and Val129 mice.
Transmission of the different scrapie isolates in these mice leads to the
emergence of prion strain phenotypes that showed similar characteristics to
those displayed by MM1 or VV2 sCJD prion. These results demonstrate that scrapie
prions have a zoonotic potential and raise new questions about the possible link
between animal and human prions.

2015. Transmission of scrapie prions to primate after an extended silent
incubation period. Scientific Reports. 5:11573.
Interpretive Summary: The transmissible spongiform encephalopathies (also
called prion diseases) are fatal neurodegenerative diseases that affect animals
and humans. The agent of prion diseases is a misfolded form of the prion protein
that is resistant to breakdown by the host cells. Since all mammals express
prion protein on the surface of various cells such as neurons, all mammals are,
in theory, capable of replicating prion diseases. One example of a prion
disease, bovine spongiform encephalopathy (BSE; also called mad cow disease),
has been shown to infect cattle, sheep, exotic undulates, cats, non-human
primates, and humans when the new host is exposed to feeds or foods contaminated
with the disease agent. The purpose of this study was to test whether non-human
primates (cynomologous macaque) are susceptible to the agent of sheep scrapie.
After an incubation period of approximately 10 years a macaque developed
progressive clinical signs suggestive of neurologic disease. Upon postmortem
examination and microscopic examination of tissues, there was a widespread
distribution of lesions consistent with a transmissible spongiform
encephalopathy. This information will have a scientific impact since it is the
first study that demonstrates the transmission of scrapie to a non-human primate
with a close genetic relationship to humans. This information is especially
useful to regulatory officials and those involved with risk assessment of the
potential transmission of animal prion diseases to humans. Technical Abstract:
Classical bovine spongiform encephalopathy (c-BSE) is an animal prion disease
that also causes variant Creutzfeldt-Jakob disease in humans. Over the past
decades, c-BSE's zoonotic potential has been the driving force in establishing
extensive protective measures for animal and human health.
*** In complement to the recent demonstration that humanized mice are
susceptible to scrapie, we report here the first observation of direct
transmission of a natural classical scrapie isolate to a macaque after a 10-year
incubation period. Neuropathologic examination revealed all of the features of a
prion disease: spongiform change, neuronal loss, and accumulation of PrPres
throughout the CNS.
*** This observation strengthens the questioning of the harmlessness of
scrapie to humans, at a time when protective measures for human and animal
health are being dismantled and reduced as c-BSE is considered controlled and
being eradicated.
*** Our results underscore the importance of precautionary and protective
measures and the necessity for long-term experimental transmission studies to
assess the zoonotic potential of other animal prion strains.

Abstract
Although Bovine Spongiform Encephalopathy (BSE) is the cause of variant
Creutzfeldt Jakob disease (vCJD) in humans, the zoonotic potential of scrapie
prions remains unknown. Mice genetically engineered to overexpress the human
prion protein (tgHu) have emerged as highly relevant models for gauging the
capacity of prions to transmit to humans. These models can propagate human
prions without any apparent transmission barrier and have been used used to
confirm the zoonotic ability of BSE. Here we show that a panel of sheep scrapie
prions transmit to several tgHu mice models with an efficiency comparable to
that of cattle BSE. The serial transmission of different scrapie isolates in
these mice led to the propagation of prions that are phenotypically identical to
those causing sporadic CJD (sCJD) in humans. These results demonstrate that
scrapie prions have a zoonotic potential and raise new questions about the
possible link between animal and human prions.
snip...
Do our transmission results in tgHu imply that sheep scrapie is the cause
of sCJD cases in humans? This question challenges well-established dogma that
sCJD is a spontaneous disorder unrelated to animal prion disease. In our
opinion, our data on their own do not unequivocally establish a causative link
between natural exposure to sheep scrapie and the subsequent appearance of sCJD
in humans. However, our studies clearly point out the need to re-consider this
possibility. Clarification on this topic will be aided by informed and modern
epidemiological studies to up-date previous analysis that was performed at the
end of the last century3, 4. The value of such an approach is highlighted by the
implementation in the year 2000 of large-scale active animal TSE surveillance
programs around the world that provided an informed epidemiological-based view
of the occurrence and geographical spread of prion disease in small ruminant
populations51. The fact that both Australia and New-Zealand, two countries that
had been considered for more than 50 years as TSE-free territories, were finally
identified positive for atypical scrapie in their sheep flocks provides an
example of how prion dogma can be reversed52. However, the incubation period for
prion disease in humans after exposure to prions via the peripheral route, such
as in iatrogenic CJD transmission and Kuru, can exceed several decades53, 54. In
this context, it will be a challenge to combine epidemiological data collected
contemporarily in animal populations and humans to investigate the existence of
a causative link between prion disease occurrence in these different hosts.
Furthermore, it is crucial to bear in mind that sporadic sCJD in humans is a
rare disease (1–2 individuals per million of the population per year) and that
scrapie has been circulating in small ruminants populations used for food
purposes for centuries. Consequently, it is our opinion that even if a causative
link was established between sheep scrapie exposure and the occurrence of
certain sCJD cases, it would be wrong to consider small ruminant TSE agents as a
new major threat for public health. Despite this, it remains clear that our data
provide a new impetus to establish the true zoonotic potential of sheep scrapie
prions.

Oral transmission of kuru, Creutzfeldt-Jakob disease, and scrapie to
nonhuman primates.
Gibbs CJ Jr, Amyx HL, Bacote A, Masters CL, Gajdusek DC.
Kuru and Creutzfeldt-Jakob disease of humans and scrapie disease of sheep
and goats were transmitted to squirrel monkeys (Saimiri sciureus) that were
exposed to the infectious agents only by their nonforced consumption of known
infectious tissues. The asymptomatic incubation period in the one monkey exposed
to the virus of kuru was 36 months; that in the two monkeys exposed to the virus
of Creutzfeldt-Jakob disease was 23 and 27 months, respectively; and that in the
two monkeys exposed to the virus of scrapie was 25 and 32 months, respectively.
Careful physical examination of the buccal cavities of all of the monkeys failed
to reveal signs or oral lesions. One additional monkey similarly exposed to kuru
has remained asymptomatic during the 39 months that it has been under
observation.
snip...
The successful transmission of kuru, Creutzfeldt-Jakob disease, and scrapie
by natural feeding to squirrel monkeys that we have reported provides further
grounds for concern that scrapie-infected meat may occasionally give rise in
humans to Creutzfeldt-Jakob disease.

AGRICULTURAL RESEARCH COUNCIL REPORT OF THE ADVISORY COMMITTE ON SCRAPIE
Office Note CHAIRMAN: PROFESSOR PETER WILDY

A The Present Position with respect to Scrapie A] The Problem Scrapie is a
natural disease of sheep and goats. It is a slow and inexorably progressive
degenerative disorder of the nervous system and it ia fatal. It is enzootic in
the United Kingdom but not in all countries. The field problem has been reviewed
by a MAFF working group (ARC 35/77). It is difficult to assess the incidence in
Britain for a variety of reasons but the disease causes serious financial loss;
it is estimated that it cost Swaledale breeders alone $l.7 M during the five
years 1971-1975. A further inestimable loss arises from the closure of certain
export markets, in particular those of the United States, to British sheep. It
is clear that scrapie in sheep is important commercially and for that reason
alone effective measures to control it should be devised as quickly as possible.
Recently the question has again been brought up as to whether scrapie is
transmissible to man. This has followed reports that the disease has been
transmitted to primates.
One particularly lurid speculation (Gajdusek 1977) conjectures that the
agents of scrapie, kuru, Creutzfeldt-Jakob disease and transmissible
encephalopathy of mink are varieties of a single "virus". The U.S. Department of
Agriculture concluded that it could "no longer justify or permit scrapie-blood
line and scrapie-exposed sheep and goats to be processed for human or animal
food at slaughter or rendering plants" (ARC 84/77)" The problem is emphasised by
the finding that some strains of scrapie produce lesions identical to the once
which characterise the human dementias" Whether true or not. the hypothesis that
these agents might be transmissible to man raises two considerations. First, the
safety of laboratory personnel requires prompt attention. Second, action such as
the "scorched meat" policy of USDA makes the solution of the acrapie problem
urgent if the sheep industry is not to suffer grievously.

IN CONFIDENCE
TRANSMISSION TO CHIMPANZEE
1. Kuru and CJD have been successfully transmitted to chimpanzees but
scrapie and TME have not.
2. We cannot say that scrapie will not transmit to chimpanzees. There are
several scrapie strains and I am not aware that all have been tried (that would
have to be from mouse passaged material). Nor has a wide enough range of field
isolates subsequently strain typed in mice been inoculated by the appropriate
routes (i/c, i/p and i v);
3. I believe the proposed experiment to determine transmissibility, if
conducted, would only show the susceptibility or resistance of the chimpanzee to
infection/disease by the routes used and the result could not be interpreted for
the predictability of the susceptibility for man. Proposals for prolonged oral
exposure of chimpanzees to milk from cattle were suggested a long while ago and
rejected.
4. In view of Dr Gibbs‘ probable use of Chimpazees Mr Wells‘ comments
(enclosed) are pertinent. I have yet to receive a direct communication from Dr
Schellekers but before any collaboration or provision of material we should
identify the Gibbs' proposals and objectives.
5. A positive result from a chimpanzee challenged severely would likely
create alarm in some circles even if the result could not be interpreted for
man. I have a view that all these agents could be transmitted provided a large
enough dose by appropriate routes was given and the animals kept long enough.
Until the mechanisms of the species barrier are more clearly understood it might
be best to retain that hypothesis.
A negative result would take a lifetime to determine but that would be a
shorter period than might be available for human exposure and it would still not
answer the question regarding mans' susceptibility. In the meantime no doubt the
negativity would be used defensively. It would however be counterproductive if
the experiment finally became positive- We may learn more about public reactions
following next Monday‘s meeting. CVO (+ Mr. Wells’ comments)

O.05: Transmission of prions to primates after extended silent incubation
periods: Implications for BSE and scrapie risk assessment in human populations

Prion diseases (PD) are the unique neurodegenerative proteinopathies
reputed to be transmissible under field conditions since decades. The
transmission of Bovine Spongiform Encephalopathy (BSE) to humans evidenced that
an animal PD might be zoonotic under appropriate conditions. Contrarily, in the
absence of obvious (epidemiological or experimental) elements supporting a
transmission or genetic predispositions, PD, like the other proteinopathies, are
reputed to occur spontaneously (atpical animal prion strains, sporadic CJD
summing 80% of human prion cases). Non-human primate models provided the first
evidences supporting the transmissibiity of human prion strains and the zoonotic
potential of BSE. Among them, cynomolgus macaques brought major information for
BSE risk assessment for human health (Chen, 2014), according to their
phylogenetic proximity to humans and extended lifetime. We used this model to
assess the zoonotic potential of other animal PD from bovine, ovine and cervid
origins even after very long silent incubation periods.
*** We recently observed the direct transmission of a natural classical
scrapie isolate to macaque after a 10-year silent incubation period,
***with features similar to some reported for human cases of sporadic CJD,
albeit requiring fourfold long incubation than BSE. Scrapie, as recently evoked
in humanized mice (Cassard, 2014),

Chronic wasting disease (CWD) is a widespread and highly transmissible
prion disease in free-ranging and captive cervid species in North America. The
zoonotic potential of CWD prions is a serious public health concern, but the
susceptibility of human CNS and peripheral organs to CWD prions remains largely
unresolved. We reported earlier that peripheral and CNS infections were detected
in transgenic mice expressing human PrP129M or PrP129V. Here we will present an
update on this project, including evidence for strain dependence and influence
of cervid PrP polymorphisms on CWD zoonosis as well as the characteristics of
experimental human CWD prions.

Cervid to human prion transmission
Kong, Qingzhong
Case Western Reserve University, Cleveland, OH, United States
Abstract
Prion disease is transmissible and invariably fatal. Chronic wasting
disease (CWD) is the prion disease affecting deer, elk and moose, and it is a
widespread and expanding epidemic affecting 22 US States and 2 Canadian
provinces so far. CWD poses the most serious zoonotic prion transmission risks
in North America because of huge venison consumption (>6 million deer/elk
hunted and consumed annually in the USA alone), significant prion infectivity in
muscles and other tissues/fluids from CWD-affected cervids, and usually high
levels of individual exposure to CWD resulting from consumption of the affected
animal among often just family and friends. However, we still do not know
whether CWD prions can infect humans in the brain or peripheral tissues or
whether clinical/asymptomatic CWD zoonosis has already occurred, and we have no
essays to reliably detect CWD infection in humans. We hypothesize that:
(1) The classic CWD prion strain can infect humans at low levels in the
brain and peripheral lymphoid tissues;
(2) The cervid-to-human transmission barrier is dependent on the cervid
prion strain and influenced by the host (human) prion protein (PrP) primary
sequence;
(3) Reliable essays can be established to detect CWD infection in
humans;and
(4) CWD transmission to humans has already occurred. We will test these
hypotheses in 4 Aims using transgenic (Tg) mouse models and complementary in
vitro approaches.
Aim 1 will prove that the classical CWD strain may infect humans in brain
or peripheral lymphoid tissues at low levels by conducting systemic bioassays in
a set of "humanized" Tg mouse lines expressing common human PrP variants using a
number of CWD isolates at varying doses and routes. Experimental "human CWD"
samples will also be generated for Aim 3.
Aim 2 will test the hypothesis that the cervid-to-human prion transmission
barrier is dependent on prion strain and influenced by the host (human) PrP
sequence by examining and comparing the transmission efficiency and phenotypes
of several atypical/unusual CWD isolates/strains as well as a few prion strains
from other species that have adapted to cervid PrP sequence, utilizing the same
panel of humanized Tg mouse lines as in Aim 1.
Aim 3 will establish reliable essays for detection and surveillance of CWD
infection in humans by examining in details the clinical, pathological,
biochemical and in vitro seeding properties of existing and future experimental
"human CWD" samples generated from Aims 1-2 and compare them with those of
common sporadic human Creutzfeldt-Jakob disease (sCJD) prions.
Aim 4 will attempt to detect clinical CWD-affected human cases by examining
a significant number of brain samples from prion-affected human subjects in the
USA and Canada who have consumed venison from CWD-endemic areas utilizing the
criteria and essays established in Aim 3. The findings from this proposal will
greatly advance our understandings on the potential and characteristics of
cervid prion transmission in humans, establish reliable essays for CWD zoonosis
and potentially discover the first case(s) of CWD infection in humans.
Public Health Relevance There are significant and increasing human exposure
to cervid prions because chronic wasting disease (CWD, a widespread and highly
infectious prion disease among deer and elk in North America) continues
spreading and consumption of venison remains popular, but our understanding on
cervid-to-human prion transmission is still very limited, raising public health
concerns. This proposal aims to define the zoonotic risks of cervid prions and
set up and apply essays to detect CWD zoonosis using mouse models and in vitro
methods. The findings will greatly expand our knowledge on the potentials and
characteristics of cervid prion transmission in humans, establish reliable
essays for such infections and may discover the first case(s) of CWD infection
in humans.

Key Molecular Mechanisms of TSEs
Zabel, Mark D.
Colorado State University-Fort Collins, Fort Collins, CO, United States
Abstract Prion diseases, or transmissible spongiform encephalopathies (TSEs),
are fatal neurodegenerative diseases affecting humans, cervids, bovids, and
ovids. The absolute requirement of PrPC expression to generate prion diseases
and the lack of instructional nucleic acid define prions as unique infectious
agents. Prions exhibit species-specific tropism, inferring that unique prion
strains exist that preferentially infct certain host species and confront
transmission barriers to heterologous host species. However, transmission
barriers are not absolute. Scientific consensus agrees that the sheep TSE
scrapie probably breached the transmission barrier to cattle causing bovine
spongiform encephalopathy that subsequently breached the human transmission
barrier and likely caused several hundred deaths by a new-variant form of the
human TSE Creutzfeldt-Jakob disease in the UK and Europe. The impact to human
health, emotion and economies can still be felt in areas like farming, blood and
organ donations and the threat of a latent TSE epidemic. This precedent raises
the real possibility of other TSEs, like chronic wasting disease of cervids,
overcoming similar human transmission barriers. A groundbreaking discovery made
last year revealed that mice infected with heterologous prion strains facing
significant transmission barriers replicated prions far more readily in spleens
than brains6. Furthermore, these splenic prions exhibited weakened transmission
barriers and expanded host ranges compared to neurogenic prions. These data
question conventional wisdom of avoiding neural tissue to avoid prion
xenotransmission, when more promiscuous prions may lurk in extraneural tissues.
Data derived from work previously funded by NIH demonstrate that Complement
receptors CD21/35 bind prions and high density PrPC and differentially impact
prion disease depending on the prion isolate or strain used. Recent advances in
live animal and whole organ imaging have led us to generate preliminary data to
support novel, innovative approaches to assessing prion capture and transport.
We plan to test our unifying hypothesis for this proposal that CD21/35 control
the processes of peripheral prion capture, transport, strain selection and
xenotransmission in the following specific aims. 1. Assess the role of CD21/35
in splenic prion strain selection and host range expansion. 2. Determine whether
CD21/35 and C1q differentially bind distinct prion strains 3. Monitor the
effects of CD21/35 on prion trafficking in real time and space 4. Assess the
role of CD21/35 in incunabular prion trafficking
Public Health Relevance Transmissible spongiform encephalopathies, or prion
diseases, are devastating illnesses that greatly impact public health,
agriculture and wildlife in North America and around the world. The impact to
human health, emotion and economies can still be felt in areas like farming,
blood and organ donations and the threat of a latent TSE epidemic. This
precedent raises the real possibility of other TSEs, like chronic wasting
disease (CWD) of cervids, overcoming similar human transmission barriers. Early
this year Canada reported its first case of BSE in over a decade audits first
case of CWD in farmed elk in three years, underscoring the need for continued
vigilance and research. Identifying mechanisms of transmission and zoonoses
remains an extremely important and intense area of research that will benefit
human and other animal populations.

PMCA Detection of CWD Infection in Cervid and Non-Cervid Species
Hoover, Edward Arthur
Colorado State University-Fort Collins, Fort Collins, CO, United States
Abstract Chronic wasting disease (CWD) of deer and elk is an emerging highly
transmissible prion disease now recognized in 18 States, 2 Canadian provinces,
and Korea. We have shown that Infected deer harbor and shed high levels of
infectious prions in saliva, blood, urine, and feces, and in the tissues
generating those body fluids and excreta, thereby leading to facile transmission
by direct contact and environmental contamination. We have also shown that CWD
can infect some non-cervid species, thus the potential risk CWD represents to
domestic animal species and to humans remains unknown. Whether prions borne in
blood, saliva, nasal fluids, milk, or excreta are generated or modified in the
proximate peripheral tissue sites, may differ in subtle ways from those
generated in brain, or may be adapted for mucosal infection remain open
questions. The increasing parallels in the pathogenesis between prion diseases
and human neurodegenerative conditions, such as Alzheimer's and Parkinson's
diseases, add relevance to CWD as a transmissible protein misfolding disease.
The overall goal of this work is to elucidate the process of CWD prion
transmission from mucosal secretory and excretory tissue sites by addressing
these questions: (a) What are the kinetics and magnitude of CWD prion shedding
post-exposure? (b) Are excreted prions biochemically distinct, or not, from
those in the CNS? (c) Are peripheral epithelial or CNS tissues, or both, the
source of excreted prions? and (d) Are excreted prions adapted for horizontal
transmission via natural/trans-mucosal routes? The specific aims of this
proposal are: (1) To determine the onset and consistency of CWD prion shedding
in deer and cervidized mice; (2); To compare the biochemical and biophysical
properties of excretory vs. CNS prions; (3) To determine the capacity of
peripheral tissues to support replication of CWD prions; (4) To determine the
protease- sensitive infectious fraction of excreted vs. CNS prions; and (5) To
compare the mucosal infectivity of excretory vs. CNS prions. Understanding the
mechanisms that enable efficient prion dissemination and shedding will help
elucidate how horizontally transmissible prions evolve and succeed, and is the
basis of this proposal. Understanding how infectious misfolded proteins (prions)
are generated, trafficked, shed, and transmitted will aid in preventing,
treating, and managing the risks associated with these agents and the diseases
they cause.
Public Health Relevance Chronic wasting disease (CWD) of deer and elk is an
emergent highly transmissible prion disease now recognized throughout the USA as
well as in Canada and Korea. We have shown that infected deer harbor and shed
high levels of infectious prions in saliva, blood, urine, and feces thereby
leading to transmission by direct contact and environmental contamination. In
that our studies have also shown that CWD can infect some non-cervid species,
the potential risk CWD may represents to domestic animal species and humans
remains unknown. The increasing parallels in the development of major human
neurodegenerative conditions, such as Alzheimer's and Parkinson's diseases, and
prion diseases add relevance to CWD as a model of a transmissible protein
misfolding disease. Understanding how infectious misfolded proteins (prions) are
generated and transmitted will aid in interrupting, treating, and managing the
risks associated with these agents and the diseases they cause.

*** The potential impact of prion diseases on human health was greatly
magnified by the recognition that interspecies transfer of BSE to humans by beef
ingestion resulted in vCJD. While changes in animal feed constituents and
slaughter practices appear to have curtailed vCJD, there is concern that CWD of
free-ranging deer and elk in the U.S. might also cross the species barrier.
Thus, consuming venison could be a source of human prion disease. Whether BSE
and CWD represent interspecies scrapie transfer or are newly arisen prion
diseases is unknown. Therefore, the possibility of transmission of prion disease
through other food animals cannot be ruled out. There is evidence that vCJD can
be transmitted through blood transfusion. There is likely a pool of unknown size
of asymptomatic individuals infected with vCJD, and there may be asymptomatic
individuals infected with the CWD equivalent. These circumstances represent a
potential threat to blood, blood products, and plasma supplies.
***********CJD REPORT 1994 increased risk for consumption of veal and
venison and lamb***********
CREUTZFELDT JAKOB DISEASE SURVEILLANCE IN THE UNITED KINGDOM THIRD ANNUAL
REPORT AUGUST 1994
Consumption of venison and veal was much less widespread among both cases
and controls. For both of these meats there was evidence of a trend with
increasing frequency of consumption being associated with increasing risk of
CJD. (not nvCJD, but sporadic CJD...tss)
These associations were largely unchanged when attention was restricted to
pairs with data obtained from relatives. ...
Table 9 presents the results of an analysis of these data.
There is STRONG evidence of an association between ‘’regular’’ veal eating
and risk of CJD (p = .0.01).
Individuals reported to eat veal on average at least once a year appear to
be at 13 TIMES THE RISK of individuals who have never eaten veal.
There is, however, a very wide confidence interval around this estimate.
There is no strong evidence that eating veal less than once per year is
associated with increased risk of CJD (p = 0.51).
The association between venison eating and risk of CJD shows similar
pattern, with regular venison eating associated with a 9 FOLD INCREASE IN RISK
OF CJD (p = 0.04).
There is some evidence that risk of CJD INCREASES WITH INCREASING FREQUENCY
OF LAMB EATING (p = 0.02).
The evidence for such an association between beef eating and CJD is weaker
(p = 0.14). When only controls for whom a relative was interviewed are included,
this evidence becomes a little STRONGER (p = 0.08).
snip...
It was found that when veal was included in the model with another
exposure, the association between veal and CJD remained statistically
significant (p = < 0.05 for all exposures), while the other exposures ceased
to be statistically significant (p = > 0.05).
snip...
In conclusion, an analysis of dietary histories revealed statistical
associations between various meats/animal products and INCREASED RISK OF CJD.
When some account was taken of possible confounding, the association between
VEAL EATING AND RISK OF CJD EMERGED AS THE STRONGEST OF THESE ASSOCIATIONS
STATISTICALLY. ...
snip...
In the study in the USA, a range of foodstuffs were associated with an
increased risk of CJD, including liver consumption which was associated with an
apparent SIX-FOLD INCREASE IN THE RISK OF CJD. By comparing the data from 3
studies in relation to this particular dietary factor, the risk of liver
consumption became non-significant with an odds ratio of 1.2 (PERSONAL
COMMUNICATION, PROFESSOR A. HOFMAN. ERASMUS UNIVERSITY, ROTTERDAM). (???...TSS)

Dear Mr Elmhirst,
CREUTZFELDT-JAKOB DISEASE (CJD) SURVEILLANCE UNIT REPORT
Thank you for your recent letter concerning the publication of the third
annual report from the CJD Surveillance Unit. I am sorry that you are
dissatisfied with the way in which this report was published.
The Surveillance Unit is a completely independant outside body and the
Department of Health is committed to publishing their reports as soon as they
become available. In the circumstances it is not the practice to circulate the
report for comment since the findings of the report would not be amended. In
future we can ensure that the British Deer Farmers Association receives a copy
of the report in advance of publication.
The Chief Medical Officer has undertaken to keep the public fully informed
of the results of any research in respect of CJD. This report was entirely the
work of the unit and was produced completely independantly of the the
Department.
The statistical results reqarding the consumption of venison was put into
perspective in the body of the report and was not mentioned at all in the press
release. Media attention regarding this report was low key but gave a realistic
presentation of the statistical findings of the Unit. This approach to
publication was successful in that consumption of venison was highlighted only
once by the media ie. in the News at one television proqramme.
I believe that a further statement about the report, or indeed statistical
links between CJD and consumption of venison, would increase, and quite possibly
give damaging credence, to the whole issue. From the low key media reports of
which I am aware it seems unlikely that venison consumption will suffer
adversely, if at all.

Stereotactic multicontact electrodes used to probe the cerebral cortex of a
middle aged woman with progressive dementia were previously implicated in the
accidental transmission of Creutzfeldt-Jakob disease (CJD) to two younger
patients. The diagnoses of CJD have been confirmed for all three cases. More
than two years after their last use in humans, after three cleanings and
repeated sterilisation in ethanol and formaldehyde vapour, the electrodes were
implanted in the cortex of a chimpanzee. Eighteen months later the animal became
ill with CJD. This finding serves to re-emphasise the potential danger posed by
reuse of instruments contaminated with the agents of spongiform
encephalopathies, even after scrupulous attempts to clean them.

CONFIRMATION OF CJD IN FOURTH FARMER
now story changes from;
SEAC concluded that, if the fourth case were confirmed, it would be
worrying, especially as all four farmers with CJD would have had BSE cases on
their farms.

This is not unexpected...
was another farmer expected?

4th farmer, and 1st teenager
2. snip...
Over a 5 year period, which is the time period on which the advice from
Professor Smith and Dr. Gore was based, and assuming a population of 120,000
dairy farm workers, and an annual incidence of 1 per million cases of CJD in the
general population, a DAIRY FARM WORKER IS 5 TIMES MORE LIKELY THAN an
individual in the general population to develop CJD. Using the actual current
annual incidence of CJD in the UK of 0.7 per million, this figure becomes 7.5
TIMES.
3. You will recall that the advice provided by Professor Smith in 1993 and
by Dr. Gore this month used the sub-population of dairy farm workers who had had
a case of BSE on their farms - 63,000, which is approximately half the number of
dairy farm workers - as a denominator. If the above sums are repeated using this
denominator population, taking an annual incidence in the general population of
1 per million the observed rate in this sub-population is 10 TIMES, and taking
an annual incidence of 0.7 per million, IT IS 15 TIMES (THE ''WORST CASE''
SCENARIO) than that in the general population...

20 year old died from sCJD in USA in 1980 and a 16 year old in 1981. A 19
year old died from sCJD in France in 1985. There is no evidence of an iatrogenic
cause for those cases....

DOES ANYONE BESIDES ME SEE A PATTERN YET ???
Vickey Rimmer, 16, DID NOT DIE FROM nvCJD, she died from a form of sporadic
CJD, whatever the hell that is. and there have been 16 year old die from
sporadic CJD in the USA as well.
SIMPLY PUT, the ukbsenvcjd only theory was wrong from day one. the elderly
are expendable, pets and kids are not.
Science was dictated by 'big buisness' after the Vickey Rimmer case with
the ukbsenvcjd only myth.
and there have been 16 year old die from sporadic CJD in the USA as
well.

I have interviewed Mrs Rimmer at my constituency surgery
IF there is nothing to hide, why is there so much SECRECY? WHY is the
Government and other Bodies trying to stop any CHANCE OF PEOPLE CONNECTING THE
TWO DISEASES. The B.S.E. problem is obvious, but if the correct measures are
taken, surely the problem could be contained, however, as it stands the lack of
investigation and interest of the possibility of B.S.E. and C.J.D. being linked
is open for speculation and surely someone has to account for peoples lives! WHY
is so much trouble being taken to convice people that B.S.E. and C.J.D. are not
linked? Guilty Conscience perhaps ? - or cover up?

made on __________ and the present position which remains that CJD cannot be
confirmed, in this case at this stage.

3. The Medical Director at ___________________ Hospital advised the
Department on 6 June that the results of ___________________ brain biopsy had
been received and that it showed NO EVIDENCE OF CJD. ______________ Hospital
subsequently issued a statement to the press to this effect and this was
publicised widely in the press (doc 1). News coverage which followed suggested
that the statement made by ________________ Hospital had been misleading (doc
2). Enquires have been made of the Medical Director at _______________ Hospital
who has CONFIRMED THAT THE STATEMENT ISSUED BY THE HOSPITAL WAS ISSUED IN ERROR.
The facts are that two pathology reports on the same piece of brain tissue were
recieved. The first report indicated that CJD was unlikely, The second report
indicated that CJD was possible, PERHAPS EVEN LIKELY, but that no definitive
diagnosis could be made before a post mortem was undertaken.

One reason for this was the _inaccuracy_ in coding of cases correctly
certified as CJD Coding is carried out by staff who are not medically qualified
and it is not surprising that coding errors occur in the processing of large
numbers of certificates. In 1982, 12,000 certificates per week were processed at
the office of population censuses and surveys by 15 coders and 6 checkers
(Alderson et al., 1983). The occurrence of both inter- and intra-observer coding
errors has been described (Curb et al., 1983) and the _inaccuracies_ of BOTH
certification and coding discovered in this study _support_ the introduction of
a more accurate system of death certificates and a more detailed and specific
coding system...

IDENTIFICATION OF CASES
Cases of CJD may be identified from death certificates, but this alone is
unlikely to provide adequate monitoring. ERRORS are made in certification and
diagnosis; in the Oxford study death certificates were obtained on a series of
known confirmed cases and CJD was mentioned in only 66% of certificates. In
another series of 175 certified cases, 42 patients were judged not to have
suffered from CJD after examination of case notes (7)...

2001 Deepthroat to Singeltary
The most frightening thing I have read all day is the report of Gambetti's
finding of a new strain of sporadic cjd in young people.........Dear God, what
in the name of all that is holy is that!!! If the US has different strains of
scrapie.....why???? than the UK...then would the same mechanisms that make
different strains of scrapie here make different strains of BSE...if the
patterns are different in sheep and mice for scrapie.....could not the BSE be
different in the cattle, in the mink, in the humans.......I really think the
slides or tissues and everything from these young people with the new strain of
sporadic cjd should be put up to be analyzed by many, many experts in
cjd........bse.....scrapie Scrape the damn slide and put it into
mice.....wait.....chop up the mouse brain and and spinal cord........put into
some more mice.....dammit amplify the thing and start the damned
research.....This is NOT rocket science...we need to use what we know and get
off our butts and move....the whining about how long everything takes.....well
it takes a whole lot longer if you whine for a year and then start the
research!!! Not sure where I read this but it was a recent press release or
something like that: I thought I would fall out of my chair when I read about
how there was no worry about infectivity from a histopath slide or tissues
because they are preserved in formic acid, or formalin or formaldehyde.....for
God's sake........ Ask any pathologist in the UK what the brain tissues in the
formalin looks like after a year.......it is a big fat sponge...the agent
continues to eat the brain ......you can't make slides anymore because the agent
has never stopped........and the old slides that are stained with Hemolysin and
Eosin......they get holier and holier and degenerate and continue...what you
looked at 6 months ago is not there........Gambetti better be photographing
every damned thing he is looking at.....
Okay, you need to know. You don't need to pass it on as nothing will come
of it and there is not a damned thing anyone can do about it. Don't even hint at
it as it will be denied and laughed at.......... USDA is gonna do as little as
possible until there is actually a human case in the USA of the nvcjd........if
you want to move this thing along and shake the earth....then we gotta get the
victims families to make sure whoever is doing the autopsy is credible,
trustworthy, and a saint with the courage of Joan of Arc........I am not
kidding!!!! so, unless we get a human death from EXACTLY the same form with
EXACTLY the same histopath lesions as seen in the UK nvcjd........forget any
action........it is ALL gonna be sporadic!!!
And, if there is a case.......there is gonna be every effort to link it to
international travel, international food, etc. etc. etc. etc. etc. They will go
so far as to find out if a sex partner had ever traveled to the UK/europe, etc.
etc. .... It is gonna be a long, lonely, dangerous twisted journey to the truth.
They have all the cards, all the money, and are willing to threaten and carry
out those threats....and this may be their biggest downfall...
Thanks as always for your help.
(Recently had a very startling revelation from a rather senior person in
government here..........knocked me out of my chair........you must keep
pushing. If I was a power person....I would be demanding that there be a least a
million bovine tested as soon as possible and agressively seeking this disease.
The big players are coming out of the woodwork as there is money to be made!!!
In short: "FIRE AT WILL"!!! for the very dumb....who's "will"! "Will be the
burden to bare if there is any coverup!"
again it was said years ago and it should be taken seriously....BSE will
NEVER be found in the US! As for the BSE conference call...I think you did a
great service to freedom of information and making some people feign
integrity...I find it scary to see that most of the "experts" are employed by
the federal government or are supported on the "teat" of federal funds. A scary
picture! I hope there is a confidential panel organized by the new government to
really investigate this thing.
You need to watch your back........but keep picking at them.......like a
buzzard to the bone...you just may get to the truth!!! (You probably have more
support than you know. Too many people are afraid to show you or let anyone else
know. I have heard a few things myself... you ask the questions that everyone
else is too afraid to ask.)

3. Prof. A. Robertson gave a brief account of BSE. The US approach was to
accord it a very low profile indeed. Dr. A Thiermann showed the picture in the
''Independent'' with cattle being incinerated and thought this was a fanatical
incident to be avoided in the US at all costs. ...
”The occurrence of CWD must be viewed against the contest of the locations
in which it occurred. It was an incidental and unwelcome complication of the
respective wildlife research programmes. Despite it’s subsequent recognition as
a new disease of cervids, therefore justifying direct investigation, no specific
research funding was forthcoming. The USDA veiwed it as a wildlife problem and
consequently not their province!” ...page 26.
