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.

Deaths linked to rare brain disease?
Two possible cases of Creutzfeldt-Jakob Disease were identified in
Cleveland County that possibly claimed the lives of two individuals in Dec. 2012
and January of this year. CJD comes in various forms and could have a relation
to mad cow disease which has never been identified or found in the county or the
state. CJD can be contracted through genetics, sporadically or through contact
with contaminated human tissues.

A type of rare, degenerative brain disease - not unlike mad cow disease -
may have claimed the lives of two county residents within the span of two
months, according to local health officials.
Deaths of two people - one in January of this year and another in December
2012 - were labeled “probable cases” of Creutzfeldt-Jakob’s disease (CJD),
according to Kim Crane, communicable disease and prevention supervisor for the
Cleveland County Health Department.
Diseases like CJD are marked by abnormal proteins called prions that can
develop in the brains of both humans and animals, according to the Centers for
Disease Control and Prevention.
About 350 deaths related to CJD were reported in the U.S. during 2009,
according to the CDC’s website.
Thirteen CJD-related deaths were reported by the NC Department of Health
and Human Services in 2010, the most recent year in which stats for disease
cases were available. None of the cases reported were related to mad cow
disease.
Crane said she wasn't allowed to release any additional information about
the individuals involved in both cases, such as age, gender, residency in the
county and additional medical information.
Varying forms of the disease
CJD comes in many forms, but two are most prominent: variant and classic.
Variant, or vCJD, has been linked to outbreaks of people eating infected
beef from animals with bovine spongiform encephalopathy (BSE), also known as
“mad cow disease.” Cases of variant CJD and BSE appeared almost simultaneously
in the United Kingdom during the early 1990s, according to the Mayo Clinic’s
website.
In 1996, three cases of CJD were identified in the US, but they were
contracted in the United Kingdom and Saudi Arabia, according to Marilyn Haskell,
a public health veterinarian and epidemiologist with the N.C. Department of
Health and Human Services.
Classic CJD occurs spontaneously in humans from abnormal brain prions. It
is not related to mad cow disease, Haskell said.
Classic CJD usually develops later in life around age 60, the CDC reports,
while the average age of people contacting CJD linked to mad cow disease is
about 28 years old.
“Having a probable case does not mean the person had CJD,” Haskell said.
No other probable or confirmed cases of CJD were reported on record in the
county, Crane said.
Confirming presence of the disease
Generally, CJD carries symptoms similar to other brain disorders such as
advanced Alzheimer’s, including dementia, memory loss, difficulty speaking and
personality changes.
A person can have classic CJD for years before symptoms surface, and most
classic forms are fatal.
CJD can only be confirmed by a human brain autopsy or biopsy after death,
according to health officials.
An autopsy wasn’t performed on either of the two probable cases in
Cleveland County, Crane said.
Autopsies to confirm CJD in North Carolina have to be arranged by the
hospital handling the case, Haskell said.
There is no known prevention or cure for classic CJD.
The disease can also be inherited through genetics or contaminated brain
tissue. Passing contaminated tissues can occur in medical procedures, including
cornea, skin transplants and even surgeries with contaminated instruments, the
Mayo Clinic reports.
The National Institute of Neurological Disorders and Stroke says forms of
CJD can’t be passed on through the air or by touching.

What is Creutzfeldt-Jakob Disease?
A rare, degenerative fatal brain disorder that affects one person in every
1 million people per year worldwide. About 200 cases are reported in the US each
year.
Symptoms of CJD
Signs of CJD can sometimes mirror Alzheimer’s Disease, including:
-Failing memory
-Behavioral changes
-Lack of coordination
-Behavioral changes
-Blindness
-Coma may occur
Most individuals with CJD die within one year after symptoms surface
What are the different forms of CJD?
- Classic or sporadic : the disease appears even though the person has no
known risk factors for the disease. This accounts for 85 percent of cases.
- Hereditary : Marked by a family history of the disease that can be tested
for a genetic mutation associated with CJD.
- Variant : Linked to people eating infected beef with bovine spongiform
encephalopathy (BSE) found in cows, also known as “mad cow disease.”
- CJD can also be transmitted through contact with contaminated brain
tissue from surgeries or medical procedures
How many cases of Creutzfeldt-Jakob Disease were reported in N.C.?
Since 2011, 13 cases of confirmed, suspected or probable types of CJD cases
were reported in the state.
*Note: No cases of variant CJD, suspected to be related to mad cow disease,
have ever been reported or identified in North Carolina.

o.k., someone explain to me how you can have a sporadic FFI, but with no
family genetic connection, and it still be a familial type prion disease, yet be
similar to the atypical h-g-BSE in the USA, but no human TSE there from in USA?
sporadic cjd, sporadic ffi, sporadic gss, now VPSPr?, all these human TSE
are simply a human TSE prion disease of _unknown_ route and source, and
officials have no clue if they are zoonosis or not.
consumption, medical, surgical, dental, friendly fire from sub-clinical TSE
consumption, to iCJD in someone else ???
all iatrogenic CJD is, is sporadic CJD until route and source of the TSE
prion agent is confirmed, and this is not done very often.
and remember, iCJD, is friendly fire from another person, i.e. the pass it
forward mode of mad cow disease.
NOW, there is evidence that some sporadic CJD is linked to the atypical BSE
and atypical Scrapie.
the UKBSEnvCJD only theory should be put to bed once and for all.
the USA and North America have more _documented_ TSE prion disease in the
wild and livestock and different species (other than zoo animals, canine and
feline TSE prion history), than any other country in the world, or continent.
consumption, sub-clinical there from, and from that, what about second hand
transmission via medical surgical, iatrogenic routes ???

EFSA Journal 2011 The European Response to BSE: A Success Story
snip...
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.

Seven main threats for the future linked to prions
First threat
The TSE road map defining the evolution of European policy for protection
against prion diseases is based on a certain numbers of hypotheses some of which
may turn out to be erroneous. In particular, a form of BSE (called atypical
Bovine Spongiform Encephalopathy), recently identified by systematic testing in
aged cattle without clinical signs, may be the origin of classical BSE and thus
potentially constitute a reservoir, which may be impossible to eradicate if a
sporadic origin is confirmed.
***Also, a link is suspected between atypical BSE and some apparently
sporadic cases of Creutzfeldt-Jakob disease in humans. These atypical BSE cases
constitute an unforeseen first threat that could sharply modify the European
approach to prion diseases.

Abstract
We report a case of iatrogenic Creutzfeldt-Jakob disease(iCJD) in a child
with a neonatal growth hormone (GH) deficiency that was treated with native
human growth hormone (hGH) between the ages of 9 months and 7 years. Three years
after the end of treatment a progressive neurological syndrome consistent with
Creutzfeldt-Jakob disease (CJD) developed, leading to death within a year, at
age 11. Neuropathological examination showed an unusual widespread form of CJD,
notably characterized by (i) involvement of the cerebellar white matter, (ii)
cortico-spinal degeneration and (iii) ballooned neurons. A transitional form of
the disease between common iatrogenic and panencephalopathic CJD is suggested.
SHORT REPORT
Creutzfeldt-Jakob disease 38 years after diagnostic use of human growth
hormone
E A Croes, G Roks, G H Jansen, P C G Nijssen, C M van Duijn
...............................................................
J Neurol Neurosurg Psychiatry 2002;72:792-793
A 47 year old man is described who developed pathology proven
Creutzfeldt-Jakob disease (CJD) 38 years after receiving a low dose of human
derived growth hormone (hGH) as part of a diagnostic procedure. The patient
presented with a cerebellar syndrome, which is compatible with iatrogenic CJD.
This is the longest incubation period described so far for iatrogenic CJD.
Furthermore, this is the first report of CJD after diagnostic use of hGH. Since
the patient was one of the first in the world to receive hGH, other cases of
iatrogenic CJD can be expected in the coming years.
Prion diseases are potentially transmissible. Human to human transmission
was first reported in 1974, when a 55 year old woman was described who developed
symptoms of Creutzfeldt-Jakob disease (CJD) 18 months after a corneal
transplant.1 Since then, transmission has been reported after stereotactic
electroencephalographic (EEG) depth recording, human growth hormone (hGH) and
gonadotrophin treatment, and dura mater transplantation.2-5 More than 267
patients with iatrogenic CJD are known today and their number is growing.6 The
most important iatrogenic cause of CJD is still contaminated cadaveric hGH.
Exposure to contaminated hGH occurred before 1985, when recombinant growth
hormone became available. In a recent study, incubation periods in 139 patients
with hGH associated CJD were found to range from 5-30 years, with a median of 12
years.6 One of the factors influencing incubation time is genotype on
polymorphic codon 129 of the prion protein gene.7 The incubation time is
significantly shorter in people who are homozygous for either methionine or
valine on this polymorphism.7
We describe the second patient with hGH related CJD in the Netherlands. The
patient developed the disease 38 years after hGH injections. To our knowledge,
this is the longest incubation period described for any form of iatrogenic CJD.
Further-more, our patient was not treated with hGH but only received a low dose
as part of a diagnostic procedure.
CASE REPORT
This patient presented at the age of 47 years with paraesthesia in both
arms for six months, difficulty with walking for four weeks, and involuntary
movements of mainly the upper extremities of two weeks' duration. He did not
notice any change in cognitive function, although his twin sister had noticed
minor memory disturbances. There was no family history of neurological disease.
During childhood the patient had experienced a growth delay compared with his
twin sister and with the average in the Netherlands. When he was 9 years old, a
nitrogen retention test with 6 IU hGH over five days was performed to exclude
growth hormone deficiency. Since the result was not decisive, a quantitative
amino acid test was performed, which measures 30 amino acids during fasting and
one, two, and three hours after growth hormone injection. No abnormal amino acid
concentrations were found making the diagnosis of primordial dwarfism most
likely. Therefore, no treatment with hGH was given.
On neurological examination we found a slight dysarthria without aphasia.
Cranial nerve function was normal. Walking was unstable and wide based. During
movements of the upper extremities myoclonic jerks were present. Sensation,
muscle tone, and strength were normal. Co-ordination was impaired in all four
limbs with a disturbed balance. Tendon reflexes were brisk at the arms and
increased at the legs with a clonus in the ankle reflex. Plantar responses were
both normal. On the mini mental state examination, the patient scored 30/30.
Routine laboratory investigation, thyroid function, vitamin concentrations (B-1,
B-6, B-12, and E), and copper metabolism were normal. Admission EEG examination
showed generalised arrhythmic slow activity with diffuse spikes and spike waves.
EEG examination two months later showed a further slowing of the rhythm with
bilateral diphasic sharp waves but was not typical for CJD. Cerebral magnetic
resonance imaging was normal. Cerebrospinal fluid examination showed 1 cell/3
µl, normal glucose and protein concentrations, and a strongly positive 14-3-3
protein test. The patient was homozygous for methionine on the PRNP codon 129
polymorphism. On clinical grounds, CJD was diagnosed. Within one month the
patient's condition deteriorated rapidly and because of severe disturbances in
coordination and progressive myoclonus he became bedridden. An eye movement
disorder developed with slow saccadic and dysmetric eye movements. Temperature
became unstable with peaks of 39°C without an infectious focus, for which a
disorder of autoregulation was presumed. Until a very advanced stage, cognitive
function was intact. The patient died five months after admission. The diagnosis
of CJD was confirmed at necropsy. The brain weighed 990 g and showed clear
cortical and cerebellar atrophy. Spongiosis, neuronal loss, and gliosis were
found predominantly in the putamen, caudate nucleus, and basotemporal and
cerebellar cortex; the cerebellum was the most severely affected of these.
Vacuoles ranged from 2-12 µm. No amyloid or Kuru plaques were found.
Immunohistochemical staining (3F4 antibody 1:1000, Senetek, USA) was clearly
positive for prion protein accumulation in a "synaptic" distribution. Most
deposition was found in the stratum moleculare of the cerebellum.
DISCUSSION
We describe a 47 year old patient who developed pathology proven CJD 38
years after hGH injections. The patient was never treated with hGH but received
a small dose as part of a diagnostic procedure. The onset of CJD was signalled
by prodromal symptoms of paraesthesia followed by a rapidly progressive ataxia.
The disease presentation and course with predominantly cerebellar and eye
movement disorders are compatible with iatrogenic CJD caused by hGH treatment.6
8
Growth hormone treatment was first described in 1958 but hGH was not
produced on a larger scale from human pituitary glands until the beginning of
the 1960s. In the Netherlands growth hormone extraction started in 1963 and was
soon centrally coordinated. Until 1979 growth hormone was extracted
non-commercially from pituitaries by a pharmaceutical company. In 1971
commercial products also became available. Our patient was one of the first to
receive hGH in the Netherlands but the origin of this product was not recorded.
A causal relation can therefore not be established with full certainty, but
coincidentally receiving growth hormone and developing this very rare disease is
unlikely. Since the clinical course in this relatively young patient is in
accordance with an iatrogenic cause, we think the probability is high that the
hGH injections explain the development of CJD in this patient.
The first Dutch patient with hGH related CJD died in 1990. 9 During several
periods from 1963 to 1969 she received intramuscular injections of hGH. During
an unknown period the hGH was derived from South America. At age 39, 27 years
after starting the treatment, she developed an ataxic gait, slurred speech,
sensory disorders, and myoclonus, but her cognitive function remained normal.
Postmortem examination of the brain confirmed the diagnosis of CJD.9 Following
the identification of this patient, a retrospective study was started to trace
all 564 registered hGH recipients who were treated before May 1985. Until
January 1995, none of these was suspected of having CJD.10 Since 1993
prospective surveillance for all forms of human prion disease has been carried
out in the Netherlands and, apart from the patient described above, a further
two patients with iatrogenic CJD have been identified, who developed the disease
after dura mater transplantation.11
An incubation period as long as 38 years had never been reported for
iatrogenic CJD. Huillard d'Aignaux et al7 studied the incubation period in 55
patients with hGH related CJD in a cohort of 1361 French hGH recipients. The
median incubation period was between 9 and 10 years. Under the most pessimistic
model, the upper limit of the 95% confidence interval varied between 17 and 20
years. Although the infecting dose cannot be quantified, it can be speculated
that the long incubation period in our patient is partly explained by the
administration of a limited amount of hGH. This hypothesis is supported by
experimental models, in which higher infecting doses usually produce shorter
incubation periods.6 Since our patient was one of the first in the world to
receive hGH, this case indicates that still more patients with iatrogenic CJD
can be expected in the coming years. Another implication of our study is that
CJD can develop even after a low dose of hGH. This case once more testifies that
worldwide close monitoring of any form of iatrogenic CJD is mandatory.

Possible iatrogenic Creutzfeldt-Jakob Disease in an adult male 50 years
after treatment with human chorionic gonadotrophin
Brian Appleby1, Paul Brown2 1Johns Hopkins University School of Medicine,
USA; 2CEA/DSV/iMETI/SEPIA, France
Background: Known causes of iatrogenic Creutzfeldt-Jakob disease (iCJD)
include cadaverous corneal transplants, dural mater grafts, human growth hormone
(hGH), neurosurgical depth electrodes, and neurosurgical instrument
contamination. Four cases of iCJD from human gonadotrophin have been described
to date, all of whom have been women.
Objectives: To present a case of possible iCJD from human chorionic
gonadotrophin (hCG) and review data from four other cases Methods: Case report
and descriptive analysis
Results: A 62-year-old Caucasian man developed ataxia that resulted in
frequent falls and an initial diagnosis of benign positional vertigo. Further
workup including brain magnetic resonance imaging (MRI), electroencephalogram
(EEG), and a lumbar puncture were unrevealing. A cerebrospinal 14-3-3 protein
analysis was indeterminate. At the end of the third month of his illness, he
developed short-term amnesia, disorientation, and confabulation. A repeat EEG
showed generalized slowing without evidence of periodic sharp wave complexes and
a repeat 14-3-3 analysis was positive. A second brain MRI showed hyperintensity
in the basal ganglia on diffusion- weighted images. He died following a
four-month illness. Severe vacuolization was noted on microscopic examination
and Western blot analyses detected type II prion proteins. Genomic analyses
detected a silent polymorphism at codon 117 and valine homozygousity at codon
129 of the prion protein gene. Further review of his medical records revealed a
history of cryptorchidism and treatment with hCG as a child in the
1940’s-1950’s.
Discussion: This case report describes a possible case of iCJD from hCG
injections and is unique in that the patient was male and the incubation period
approached 50 years. His clinical presentation, EEG findings, and codon 129
homozygousity are similar to previously described cases.

3. The first case is that of CJD in a 19 year old boy. This is already
publicly known and was the subject of a ''World In Action'' programme over the
summer. The second case is in a 17 year old girl, and is the one I reported to
the Minister in my minute of 22 September. This patient is still alive, but CJD
has been confirmed by brain biopsy. This will be the first time in which this

2. Sporadic CJD normally occurs in people in their 50s and 60s although it
can occur more rarely in younger age groups. Until this year the youngest case
of sporadic CJD in the UK had been in a 34 year old. Other countries, howver,
have reported sporadic CJD in teenagers. Those we know about are;
* in the USA, a 16 year old in 1978;
* in France, a 19 year old in 1982;
* in Canada, a 14 year old of UK origin in 1988;
* in Poland cases in people aged 19, 23, and 27 were identified in a
retrospective study (published 1991), having been originally misdiagnosed with a
viral encephalitis;
* Creutzfeldt's first patient in 1920 was aged 23.

Abstract
Background: Sporadic Creutzfeldt-Jakob disease (CJD) is a condition
predominantly affecting older age groups, with cases aged less than 45 years
rare and an age at onset or death of less than 20 years exceptional.
Methods: Data from the systematic study of sporadic CJD in the UK are
available from 1970 onwards. Clinical and pathological data are reviewed in
order to identify atypical cases, including those at the extremes of the age
range of sporadic CJD. Detailed analysis of atypical cases is undertaken and in
selected cases laboratory transmission studies are carried out in order to
provide information on the characteristics of the infectious agent.
Results: In the UK two cases of sporadic CJD in adolescents have been
identified, dying aged 16 and 20 years. The first case predated the epidemic of
bovine spongiform encephalopathy and the characteristics of the second case,
including laboratory transmission studies, are consistent with a diagnosis of
sporadic rather than variant CJD.
Conclusion: The cases in this report indicate that sporadic CJD can develop
at a very young age, that variant CJD is not the only form of CJD occurring in
this age group and that neuropathological examination is essential to accurate
diagnosis of human prion disease.

Creutzfeldt-Jakob disease (CJD) biannual update (February 2013) Infection report/CJD
Infection report/CJD
Creutzfeldt-Jakob disease (CJD) biannual update (February 2013)
This six-monthly report provides an update on reports of incidents of
potential iatrogenic (healthcare-acquired) exposures to CJD. The data is correct
as of 31st December 2012. For numbers of CJD case reports, readers should
consult data provided by the National CJD Research and Surveillance Unit
(NCJDRSU), Edinburgh [1]. The latest yearly analysis of vCJD reports (onsets and
deaths) is also available from the NCJDRSU website [2].
Reports of incidents of potential iatrogenic exposure to CJD via surgery:
2000 to 2012
A surgical incident occurs when a patient with or at ‘increased risk’ of
CJD has undergone surgery without the appropriate infection control guidance
being followed [3]. This could occur if an asymptomatic patient undergoes
surgery during the incubation period of CJD, or because information for those
potentially at risk of CJD is not available at the time of surgery. If this
happens, surgical instruments may be contaminated with the infectious agent that
causes CJD. These instruments could then pose a transmission risk when they are
re-used on other patients.
In June 2010 a distinction was made between surgical incidents and CJD
reports. Only CJD cases (or patients at ‘increased risk’ of CJD) who have
undergone surgical procedures which are thought to pose a possible transmission
risk (i.e. within the likely infectious incubation period, and involving medium
or high risk procedures) are categorised as 'surgical incidents'. Other
procedures, either earlier in the incubation period, or involving low
infectivity tissues, are categorised as 'CJD reports'. If the investigation of a
surgical incident identifies any instruments that are considered to be
potentially contaminated with the infectious agent, and that could still pose an
infection risk to other patients, the Panel advises that these instruments
should be removed from general use or refurbished. These instruments may be
quarantined, kept for exclusive use on the index patient, refurbished
(endoscopes only) or destroyed.
Since 2000 there have been 92 incidents in which instruments have been
permanently removed from general use or refurbished (endoscopes only).
Table 1 shows the number of CJD surgical incidents and reports notified to
the CJD Incidents Panel by the diagnosis of the index patient from 2000 to 2012.
Advice has been issued for 7 surgical incidents and 25 surgical reports that
were notified to the CJD Incidents Panel in 2012.

Health Protection Report Vol 7 No. 6 - 8 February 2013
Surgical incidents resulting in ‘at risk’ patients
The Panel may advise contacting and informing patients of their possible
exposure to CJD following a surgical incident. These patients should be
considered 'at risk of CJD for public health purposes' and are asked to take
certain precautions (i.e. not to donate blood, other tissues or organs, and to
inform their medical and dental carers prior to any invasive procedures) in
order to reduce the risk of transmitting the CJD agent.
The diagnosis of the index patient; the timing of the procedure relative to
the development of clinical CJD; the tissue that instruments were in contact
with during the procedure on the index patient; and the number of cycles of
re-use and decontamination the instruments have been through following the
procedure on the index case – all influence the possible risk to subsequent
patients.
The threshold level of risk at which patients are considered to be ‘at
increased risk’ of CJD is 1%, in addition to the background risk in the UK
population. This risk threshold is based on risk assessment models, using
precautionary assumptions. The 1% threshold level is used as a cut off for
implementing public health precautions and is not intended to be a precise
measure of an individual patient's risk. A similar threshold is used for
identifying other patients who have been exposed to possible CJD risks following
surgical, blood, plasma and tissue incidents.
From 2000 to 31st December 2012, there have been 29 surgical incidents in
which the Panel has advised that 192 patients should be considered to have an
increased risk of CJD.
Patient denotifications
Following changes in the assessment of tissue infectivity and procedural
risks in 2005 and 2009, the Panel has advised that 38 patients in 14 surgical
incidents who were originally considered (and notified) as being ‘at risk' of
CJD should no longer be considered ‘at risk', and should be denotified.
The Panel has received confirmation that of the 34 patients originally
notified of their exposure (out of the 38 originally considered to be ‘at
risk'), 26 patients have been informed that they are no longer considered ‘at
risk' and eight patients died before they could be denotified.
Relating to surgical instruments there are 15 surgical incidents in which
154 patients are still considered to be at increased risk of CJD. Currently, 119
of these 'at risk' patients are alive and notified of their increased risk of
CJD. Local decisions have been taken not to notify two patients in these
incidents.
Monitoring of patients 'at increased risk' of CJD
The CJD Incidents Panel and the Advisory Committee on Dangerous Pathogens
Transmissible Spongiform Encephalopathy Risk Management Subgroup (formerly the
ACDP TSE Working Group) have identified a range of individuals and groups who
may have been exposed to an increased risk of CJD as a consequence of their
medical care (see table 2 below). The risks of iatrogenic CJD transmission to
these different individuals are very uncertain, but potentially devastating. The
CJD Incidents Panel has advised that these individuals should be informed of
their risk and asked to follow public health precautions to avoid transmitting
the infection to others.
It is important to follow up these individuals to help determine the risks
of CJD spreading to patients through different routes. Follow up involves a
range of activities and is carried out by different organisations. At core,
follow up aims to ascertain whether any people who may have been exposed to
increased CJD risks go on to develop CJD.

a These are minimum figures. Central reporting for bleeding disorder
patients is incomplete, and seven patients have opted out of the central UKHCDO
database. A small number of ‘at risk’ growth hormone recipients are not included
in the Institute of Child Health study. Not all of ‘at risk’ growth hormone
recipients have been notified. There is no central record of who has been
informed.
b An asymptomatic infection is when an individual does not exhibit any of
the signs and symptoms of CJD in life but abnormal prion protein indicative of
CJD infection has been found in tissue obtained from them. In these cases the
abnormal prion protein was identified during post mortem after the individuals
had died of other causes.
