CJD
 
 
 
CJD UPDATE
From 1998 to August 1, 2010, the CJDSS has investigated 1082 patient referrals. Of the 1082 referrals, 482 cases of CJD were confirmed by pathology or diagnosed on a clinical basis. The only way to confirm a diagnosis of CJD is through a brain autopsy. Of all cases of CJD identified by the CJDSS to date, 84.1% have been confirmed in this way. This is one of the highest percentages reached by any country that carries out national CJD surveillance. This is because people (including physicians) remain aware of the disease, and because Canada maintains high-quality laboratory testing services.
The CJDSS uses rules set by the World Health Organization (WHO) when deciding a diagnosis of CJD. As shown in the graph, case referrals to the CJDSS have been relatively steady over time. Each year since 1999 about 80-100 patients have been referred to the CJDSS. From these referrals the CJDSS has recorded an average of 37.3 Canadian CJD cases per year from 1999 to 2009, which means an average of 1.17 cases per million people per year. This rate is consistent with worldwide rates of occurrence.
The success of CJDSS surveillance activities also depends on support and cooperation from physicians and other healthcare professionals caring for patients with CJD, as well as those affected by this disease. The CJDSS will continue to help physicians and other healthcare professionals to identify and understand all suspected cases of CJD in Canada, and to help affected families to better understand the disease.

BLOOD TRANSFUSION AND PRION DISEASES (CJD)
By Dr. Mindy Goldman, Executive Medical Director, Donor & Transplantation Services, Canadian Blood Services The issue of blood transfusion and CJD is of the utmost importance. In our feature article, Dr. Goldman explains how this issue affects families who have been touched by CJD.
Because of prion diseases (CJD), some people are not allowed to give blood. There have not been any cases of CJD from blood transfusion in Canada. However, because there is no test to detect this disease in blood donors, all donors must answer a list of questions about risks for CJD before giving blood. There are two main kinds of CJD (classic and variant). These two diseases are treated differently because they have different risks for blood transfusion.
Classic CJD
Classic CJD usually arises without warning and for no specific reason. No cases of classic CJD transmission have been linked to a blood transfusion. However, this disease can also be caused by genetic changes or, very rarely, by infection during certain medical procedures. Potential blood donors are therefore screened out (deferred) if any close relatives (parent, child, brother or sister) have had CJD.
Potential blood donors are also screened out if they have received dura mater (a material used in some kinds of surgery) or treatment with human pituitary hormones, since these treatments have been linked with classic CJD.
Variant CJD
Variant CJD is a human prion disease caused by infection with a prion disease of cattle (BSE, sometimes called “mad cow disease”). Between 1996 and 2010, approximately 220 people have been found to have variant CJD, mainly in the United Kingdom and Europe. Four of these people, all in the United Kingdom, are believed to have been infected by blood transfusion. Potential blood donors are therefore screened out if they have spent enough time in countries that have or may have BSE, or if they had a transfusion in one of these countries. This period of time is a total of three months or more in the United Kingdom or France from January 1, 1980 to December 31, 1996, or five years or more in the rest of Europe since January 1, 1980. Deferral policies are based on the magnitude of exposure to BSE in various countries.

YOU ASKED US
This section gives us a chance to answer questions you may have when dealing with CJD. The CJDSS also invites you to contact us directly if you have any questions, comments or concerns - toll free at 1-888-489-2999 or via email at CJDSS@phac-aspc.gc.ca.
Q. I’ve recently been caring for someone with CJD. Am I at risk of catching this disease?
A. No, physicians and scientists who study CJD do not believe you can catch it by caring for someone with the disease. You cannot catch the disease by social or sexual contact either. However, special care is taken when contact with the person’s tissues is possible, such as during specific kinds of surgery, when handling samples in laboratories, and during an autopsy. Funeral service workers must also take special care when handling a person’s remains.
Q. Why does a nurse from the CJDSS need to speak with me?
A. The CJDSS employs nurse investigators across Canada to visit and interview families affected by CJD. Families are always asked for their consent before the actual interview and chart review take place. Interviews are conducted because we need to be vigilant in identifying potential public health risks. During this interview, the nurse completes a questionnaire to collect information about a patient’s medical history and possible risks. The nurse also collects medical information by reviewing the CJD patient’s medical charts.
Q. Why is an autopsy required?
A. Firstly, post-mortem examination is not compulsory when CJD is suspected - the doctor always requires the permission of the next of kin. However, because it is the only way, at the moment, to definitively diagnose CJD, this knowledge is often very helpful for families. During the autopsy, only the brain is removed and examined because prions (which are believed to be the cause of CJD) mostly accumulate here. The procedure takes place in a facility that has specialized equipment and staff are trained to ensure respect for the patient is always maintained and safety standards are followed.
CONSENT FORM FOR DONATION OF BIOLOGICAL MATERIALS
Continued research is the key to finding answers to the many questions around CJD. This research may lead to improved diagnostic tests, better understanding of the causes of CJD, and better ways to deal with public health risks. Unused portions of the specimens of blood, brain tissue and spinal fluid that are received by the CJDSS for laboratory testing can also help us make new discoveries and further advance our knowledge of this difficult disease. All participants or their representatives are asked whether or not these specimens may be used in future research, and to sign the Donation of Biological Materials for Research consent form. Please call 1-888-489-2999 if you have not completed this form but wish to do so, or would like more information. The CJDSS is very grateful for your participation.

National Prion Disease Pathology Surveillance Center Cases Examined (July 31, 2010)
(please watch and listen to the video and the scientist speaking about atypical BSE and sporadic CJD and listen to Professor Aguzzi)
THE steady rise of sporadic CJD cases in Canada AND USA, with many unusual cases of ''PENDING CLASSIFICATIONS" which have been pending now FOR 5 YEARS, seem to be highly suspicious to me. ...TSS
The most recent assessments (and reassessments) were published in June 2005 (Table I; 18), and included the categorisation of Canada, the USA, and Mexico as GBR III. Although only Canada and the USA have reported cases, the historically open system of trade in North America suggests that it is likely that BSE is present also in Mexico.

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.
Second threat

Rural and Regional Affairs and Transport References Committee
The possible impacts and consequences for public health, trade and agriculture of the Government's decision to relax import restrictions on beef Final report June 2010
2.65 At its hearing on 14 May 2010, the committee heard evidence from Dr Alan Fahey who has recently submitted a thesis on the clinical neuropsychiatric, epidemiological and diagnostic features of Creutzfeldt-Jakob disease.48 Dr Fahey told the committee of his concerns regarding the lengthy incubation period for transmissible spongiform encephalopathies, the inadequacy of current tests and the limited nature of our current understanding of this group of diseases.49
2.66 Dr Fahey also told the committee that in the last two years a link has been established between forms of atypical CJD and atypical BSE. Dr Fahey said that: They now believe that those atypical BSEs overseas are in fact causing sporadic Creutzfeldt-Jakob disease. They were not sure if it was due to mad sheep disease or a different form. If you look in the textbooks it looks like this is just arising by itself. But in my research I have a summary of a document which states that there has never been any proof that sporadic Creutzfeldt-Jakob disease has arisen de novo-has arisen of itself. There is no proof of that. The recent research is that in fact it is due to atypical forms of mad cow disease which have been found across Europe, have been found in America and have been found in Asia. These atypical forms of mad cow disease typically have even longer incubation periods than the classical mad cow disease.50
Atypical BSE in Cattle
To date the OIE/WAHO assumes that the human and animal health standards set out in the BSE chapter for classical BSE (C-Type) applies to all forms of BSE which include the H-type and L-type atypical forms. This assumption is scientifically not completely justified and accumulating evidence suggests that this may in fact not be the case. Molecular characterization and the spatial distribution pattern of histopathologic lesions and immunohistochemistry (IHC) signals are used to identify and characterize atypical BSE. Both the L-type and H-type atypical cases display significant differences in the conformation and spatial accumulation of the disease associated prion protein (PrPSc) in brains of afflicted cattle. Transmission studies in bovine transgenic and wild type mouse models support that the atypical BSE types might be unique strains because they have different incubation times and lesion profiles when compared to C-type BSE. When L-type BSE was inoculated into ovine transgenic mice and Syrian hamster the resulting molecular fingerprint had changed, either in the first or a subsequent passage, from L-type into C-type BSE.
In addition, non-human primates are specifically susceptible for atypical BSE as demonstrated by an approximately 50% shortened incubation time for L-type BSE as compared to C-type. Considering the current scientific information available, it cannot be assumed that these different BSE types pose the same human health risks as C-type BSE or that these risks are mitigated by the same protective measures.
This study will contribute to a correct definition of specified risk material (SRM) in atypical BSE. The incumbent of this position will develop new and transfer existing, ultra-sensitive methods for the detection of atypical BSE in tissue of experimentally infected cattle.

Increased Atypical Scrapie Detections
Press reports indicate that increased surveillance is catching what otherwise would have been unreported findings of atypical scrapie in sheep. In 2009, five new cases have been reported in Quebec, Ontario, Alberta, and Saskatchewan. With the exception of Quebec, all cases have been diagnosed as being the atypical form found in older animals. Canada encourages producers to join its voluntary surveillance program in order to gain scrapie-free status. The World Animal Health will not classify Canada as scrapie-free until no new cases are reported for seven years. The Canadian Sheep Federation is calling on the government to fund a wider surveillance program in order to establish the level of prevalence prior to setting an eradication date. Besides long-term testing, industry is calling for a compensation program for farmers who report unusual deaths in their flocks.

Transmission of atypical BSE in humanized mouse models
Liuting Qing1, Wenquan Zou1, Cristina Casalone2, Martin Groschup3, Miroslaw Polak4, Maria Caramelli2, Pierluigi Gambetti1, Juergen Richt5, Qingzhong Kong1 1Case Western Reserve University, USA; 2Instituto Zooprofilattico Sperimentale, Italy; 3Friedrich-Loeffler-Institut, Germany; 4National Veterinary Research Institute, Poland; 5Kansas State University (Previously at USDA National Animal Disease Center), USA
Background: Classical BSE is a world-wide prion disease in cattle, and the classical BSE strain (BSE-C) has led to over 200 cases of clinical human infection (variant CJD). Atypical BSE cases have been discovered in three continents since 2004; they include the L-type (also named BASE), the H-type, and the first reported case of naturally occurring BSE with mutated bovine PRNP (termed BSE-M). The public health risks posed by atypical BSE were largely undefined.
Objectives: To investigate these atypical BSE types in terms of their transmissibility and phenotypes in humanized mice. Methods: Transgenic mice expressing human PrP were inoculated with several classical (C-type) and atypical (L-, H-, or Mtype) BSE isolates, and the transmission rate, incubation time, characteristics and distribution of PrPSc, symptoms, and histopathology were or will be examined and compared.
Results: Sixty percent of BASE-inoculated humanized mice became infected with minimal spongiosis and an average incubation time of 20-22 months, whereas only one of the C-type BSE-inoculated mice developed prion disease after more than 2 years. Protease-resistant PrPSc in BASE-infected humanized Tg mouse brains was biochemically different from bovine BASE or sCJD. PrPSc was also detected in the spleen of 22% of BASE-infected humanized mice, but not in those infected with sCJD. Secondary transmission of BASE in the humanized mice led to a small reduction in incubation time.*** The atypical BSE-H strain is also transmissible with distinct phenotypes in the humanized mice, but no BSE-M transmission has been observed so far.
Discussion: Our results demonstrate that BASE is more virulent than classical BSE, has a lymphotropic phenotype, and displays a modest transmission barrier in our humanized mice. BSE-H is also transmissible in our humanized Tg mice. The possibility of more than two atypical BSE strains will be discussed.

Classical BSE is a world-wide prion disease in cattle, and the classical BSE strain (BSE-C) has led to over 200 cases of clinical human infection (variant CJD). Two atypical BSE strains, BSE-L (also named BASE) and BSE-H, have been discovered in three continents since 2004. The first case of naturally occurring BSE with mutated bovine PrP gene (termed BSE-M) was also found in 2006 in the USA. The transmissibility and phenotypes of these atypical BSE strains/isolates in humans were unknown. We have inoculated humanized transgenic mice with classical and atypical BSE strains (BSE-C, BSE-L, BSE-H) and the BSE-M isolate. We have found that the atypical BSE-L strain is much more virulent than the classical BSE-C.*** The atypical BSE-H strain is also transmissible in the humanized transgenic mice with distinct phenotype, but no transmission has been observed for the BSE-M isolate so far.

This new prionopathy in humans? the genetic makeup is IDENTICAL to the g-h-BSEalabama mad cow, the only _documented_ mad cow in the world to date like this, ......wait, it get's better. this new prionpathy is killing young and old humans, with LONG DURATION from onset of symptoms to death, and the symptoms are very similar to nvCJD victims, OH, and the plaques are very similar in some cases too, bbbut, it's not related to the g-h-BSEalabama cow, WAIT NOW, it gets even better, the new human prionpathy that they claim is a genetic TSE, has no relation to any gene mutation in that family. daaa, ya think it could be related to that mad cow with the same genetic make-up ??? there were literally tons and tons of banned mad cow protein in Alabama in commerce, and none of it transmitted to cows, and the cows to humans there from ??? r i g h t $$$ ALABAMA MAD COW g-h-BSEalabama In this study, we identified a novel mutation in the bovine prion protein gene (Prnp), called E211K, of a confirmed BSE positive cow from Alabama, United States of America. This mutation is identical to the E200K pathogenic mutation found in humans with a genetic form of CJD. This finding represents the first report of a confirmed case of BSE with a potential pathogenic mutation within the bovine Prnp gene. We hypothesize that the bovine Prnp E211K mutation most likely has caused BSE in "the approximately 10-year-old cow" carrying the E221K mutation.

BSE Case Associated with Prion Protein Gene Mutation (g-h-BSEalabama) and VPSPr PRIONPATHY (see mad cow feed in COMMERCE IN ALABAMA...TSS)
her healthy calf also carried the mutation (J. A. Richt and S. M. Hall PLoS Pathog. 4, e1000156; 2008).
This raises the possibility that the disease could occasionally be genetic in origin. Indeed, the report of the UK BSE Inquiry in 2000 suggested that the UK epidemic had most likely originated from such a mutation and argued against the scrapierelated assumption. Such rare potential pathogenic PRNP mutations could occur in countries at present considered to be free of BSE, such as Australia and New Zealand. So it is important to maintain strict surveillance for BSE in cattle, with rigorous enforcement of the ruminant feed ban (many countries still feed ruminant proteins to pigs). Removal of specified risk material, such as brain and spinal cord, from cattle at slaughter prevents infected material from entering the human food chain. Routine genetic screening of cattle for PRNP mutations, which is now available, could provide additional data on the risk to the public. Because the point mutation identified in the Alabama animals is identical to that responsible for the commonest type of familial (genetic) CJD in humans, it is possible that the resulting infective prion protein might cross the bovine-human species barrier more easily. Patients with vCJD continue to be identified. The fact that this is happening less often should not lead to relaxation of the controls necessary to prevent future outbreaks. Malcolm A.

P.9.21 Molecular characterization of BSE in Canada
Jianmin Yang1, Sandor Dudas2, Catherine Graham2, Markus Czub3, Tim McAllister1, Stefanie Czub1 1Agriculture and Agri-Food Canada Research Centre, Canada; 2National and OIE BSE Reference Laboratory, Canada; 3University of Calgary, Canada
Background: Three BSE types (classical and two atypical) have been identified on the basis of molecular characteristics of the misfolded protein associated with the disease. To date, each of these three types have been detected in Canadian cattle.
Objectives: This study was conducted to further characterize the 16 Canadian BSE cases based on the biochemical properties of there associated PrPres.
Methods: Immuno-reactivity, molecular weight, glycoform profiles and relative proteinase K sensitivity of the PrPres from each of the 16 confirmed Canadian BSE cases was determined using modified Western blot analysis. Results: Fourteen of the 16 Canadian BSE cases were C type, 1 was H type and 1 was L type. The Canadian H and L-type BSE cases exhibited size shifts and changes in glycosylation similar to other atypical BSE cases. PK digestion under mild and stringent conditions revealed a reduced protease resistance of the atypical cases compared to the C-type cases. N terminal- specific antibodies bound to PrPres from H type but not from C or L type. The C-terminal-specific antibodies resulted in a shift in the glycoform profile and detected a fourth band in the Canadian H-type BSE.
Discussion: The C, L and H type BSE cases in Canada exhibit molecular characteristics similar to those described for classical and atypical BSE cases from Europe and Japan. This supports the theory that the importation of BSE contaminated feedstuff is the source of C-type BSE in Canada. *** It also suggests a similar cause or source for atypical BSE in these countries.

Groschup3, Anne Buschmann3, Cristina Casalone4, Maria Caramelli4, Salvatore Monaco5, Gianluigi Zanusso5, Fabrizio Tagliavini1 1Carlo Besta" Neurological Institute,Italy; 2IZS Brescia, Italy; 33FLI Insel Riems, D, Germany; 4CEA-IZS Torino, Italy; 5University of Verona, Italy
Background: BASE is an atypical form of bovine spongiform encephalopathy caused by a prion strain distinct from that of BSE. Upon experimental transmission to cattle, BASE induces a previously unrecognized disease phenotype marked by mental dullness and progressive atrophy of hind limb musculature. Whether affected muscles contain infectivity is unknown. This is a critical issue since the BASE strain is readily transmissible to a variety of hosts including primates, suggesting that humans may be susceptible.
Objectives: To investigate the distribution of infectivity in peripheral tissues of cattle experimentally infected with BASE. Methods: Groups of Tg mice expressing bovine PrP (Tgbov XV, n= 7-15/group) were inoculated both i.c. and i.p. with 10% homogenates of a variety of tissues including brain, spleen, cervical lymph node, kidney and skeletal muscle (m. longissimus dorsi) from cattle intracerebrally infected with BASE. No PrPres was detectable in the peripheral tissues used for inoculation either by immunohistochemistry or Western blot.
Results: Mice inoculated with BASE-brain homogenates showed clinical signs of disease with incubation and survival times of 175±15 and 207±12 days. Five out of seven mice challenged with skeletal muscle developed a similar neurological disorder, with incubation and survival times of 380±11 and 410±12 days. At present (700 days after inoculation) mice challenged with the other peripheral tissues are still healthy. The neuropathological phenotype and PrPres type of the affected mice inoculated either with brain or muscle were indistinguishable and matched those of Tgbov XV mice infected with natural BASE.
Discussion: Our data indicate that the skeletal muscle of cattle experimentally infected with BASE contains significant amount of infectivity, at variance with BSE-affected cattle, raising the issue of intraspecies transmission and the potential risk for humans. Experiments are in progress to assess the presence of infectivity in skeletal muscles of natural BASE.

comment submission Document ID APHIS-2008-0010-0001 Greetings USDA, OIE et al, what a difference it makes with science, from one day to the next. i.e. that mad cow gold card the USA once held. up until that fateful day in December of 2003, the science of BSE was NO IMPORTS TO USA FROM BSE COUNTRY. what a difference a day makes$ now that the shoe is on the other foot, the USDA via the OIE, wants to change science again, just for trade $ I implore the OIE decision and policy makers, for the sake of the world, to refuse any status quo of the USA BSE risk assessment. if at al, the USA BSE GBR should be raise to BSE GBR IV, for the following reasons. North America is awash with many different TSE Prion strains, in many different species, and they are mutating and spreading. IF the OIE, and whatever policy makers, do anything but raise the risk factor for BSE in North America, they I would regard that to be highly suspicious. IN fact, it would be criminal in my opinion, because the OIE knows this, and to knowingly expose the rest of the world to this dangerous pathogen, would be ‘knowingly’ and ‘willfully’, just for the almighty dollar, once again. I warned the OIE about all this, including the risk factors for CWD, and the fact that the zoonosis potential was great, way back in 2002. THE OIE in collaboration with the USDA, made the legal trading of the atypical Nor-98 Scrapie a legal global commodity. yes, thanks to the OIE and the USDA et al, it’s now legal to trade the atypical Nor-98 Scrapie strain all around the globe. IF you let them, they will do the same thing with atypical BSE and CWD (both strains to date). This with science showing that indeed these TSE prion strains are transmissible. I strenuously urge the OIE et al to refuse any weakening to the USA trade protocols for the BSE TSE prion disease (all strains), and urge them to reclassify the USA with BSE GBR IV risk factor.

In 2009, a pathologist with sporadic Creutzfeldt–Jakob Disease (sCJD) was reported to the Spanish registry. This case prompted a request for information on health-related occupation in sCJD cases from countries participating in the European Creutzfeldt Jakob Disease Surveillance network (EuroCJD). Responses from registries in 21 countries revealed that of 8,321 registered cases, 65 physicians or dentists, two of whom were pathologists, and another 137 healthcare workers had been identified with sCJD. Five countries reported 15 physicians and 68 other health professionals among 2,968 controls or non-cases, suggesting no relative excess of sCJD among healthcare professionals. A literature review revealed: (i) 12 case or small case-series reports of 66 health professionals with sCJD, and (ii) five analytical studies on health-related occupation and sCJD, where statistically significant findings were solely observed for persons working at physicians' offices (odds ratio: 4.6 (95 CI: 1.2–17.6)). We conclude that a wide spectrum of medical specialities and health professions are represented in sCJD cases and that the data analysed do not support any overall increased occupational risk for health professionals. Nevertheless, there may be a specific risk in some professions associated with direct contact with high human-infectivity tissue.

Results

Individualised occupational data from national CJD surveillance teams

Health professionals among registered sCJD cases A total of 202 health professionals were listed among 8,321 cases of sCJD registered by 21 respondent countries participating in EuroCJD (Table 1). Of these, 65 (32%) were physicians and 137 were other healthcare workers. The highest numbers by medical speciality were general practitioners (n=9), surgeons (n=7), internists (n=7), dentists (n=4), ophthalmologists (n=3) and pathologists (n=2). The proportion of physicians or dentists among all registered sCJD cases was 65/8,321 (0.8%).

Discussion

Despite a number of case reports of sCJD in physicians and technicians, the findings of this EuroCJD survey do not suggest an increased risk of sCJD in health professionals, nor do analytical studies show a clear excess risk for health-related professions. Methodological limitations of analytical studies in which occupational data were frequently provided by informants who were probably aware of the sCJD diagnosis [3-7,26] argue in favour of a cautious interpretation of the positive association reported for persons working at physicians’ offices [19]. Consequently, the main finding of this literature review and complementary EuroCJD observation is that health professionals, including medical staff, are not at greater risk of developing sCJD. However, this cannot exclude the possibility that there may be an occupational risk in specific circumstances, for example, for people in contact with high-risk central nervous system tissue, and appropriate precautions, as recommended by national authorities, should therefore be followed, particularly regarding laboratory work.

Although in some studies occupation was specifically analysed [19,25] and occupation may be the subject of specific inquiry in some surveillance systems, a limitation of some registries and scientific studies is that occupation may not have been systematically recorded. When occupation was recorded, it is unlikely that a framework for consistent occupational data collection was used, so that neither registries nor case–control studies have incorporated the classic epidemiological double approach. Recording of occupation may not identify specific chemical or biological exposures, which would require data for professions (job titles, medical specialisations) being cross-referenced with branches of activity (laboratory, administrative or clinical patient-contact work). The lack of registered surveillance data that combine profession with activity (e.g. contact with human tissue), when compared with the descriptions from previous case reports and the incident in Spain, illustrates the limits of the validity of available data for analytical purposes and precludes formal use of statistical testing. Although our study does not provide evidence of an excess risk of sCJD in health professionals, the fact that the data collected were mainly linked to medical speciality rather than actual activity might have concealed an excess risk of sCJD for some specific health professionals.

A case–control study seeking to examine the putative occupational risk posed by surgical injuries should have a biologically clear working hypothesis and a custom-tailored methodology. Matrices designed by linking medical speciality and surgical/forensic-anatomical/pathological activity, in which the health professional can come into direct contact with high human-infectivity tissue by accident might not provide a sufficient background for analysis, without appropriate control being made for the influence of PRNP genotype, surgical or laboratory work history and long latency. Assuming that among non-cases or controls the proportion of medical specialities with potential exposure (surgeons, forensic surgeons and other surgical specialists, pathologists) may be low, i.e. approximately 1 per 1,000 (based on the figures of 3/2,968 in Table 2), the study size that would afford the necessary statistical power for a proper examination of the specific practices of health professions is higher than that provided by existing CJD registries in any one country. Since complementary analyses would be needed for professional and activity categories defined in terms of temporal references that have not been explored to date, such as ‘ever employed’ or ‘currently employed’, as well as duration of employment, requirements for study size and collaboration would be even higher.

In conclusion, a wide spectrum of medical specialities and health professions are represented in sCJD registries. Although selection due to higher ascertainment may lie behind the case reports of certain professions involved in clinical management or care of patients with sCJD, the biological significance of these observations remains uncertain and available data do not indicate an increased risk of sCJD in health professionals. However, the methodological issues mentioned above indicate the need for caution in drawing conclusions from the data and large-scale studies with specific causal hypotheses are needed in order for further research to be undertaken into the potential link between health professions and sCJD.

Pathologist dies of suspected Creutzfeldt-Jakob (Mad cow) disease

29 March, 2009 03:33:00

Creutzfeldt-Jakob disease (mad cow) research pathologist Antonio Ruiz Villaescusa died Sat., March 28, from the disease. Colleagues suspect he may have contracted the disease from exposure to infected human tissue, according to the Barcelona Reporter newspaper.

Ruiz headed the department of pathology at the University Hospital in Madrid and was studying whether the disease is passed on to people who have been exposed to infected tissue.

The head of the pathology department at the Fundación Alcorcón, Dr. Radish, will perform an autopsy to clarify the cause of death and the final results will be announced in about a month, according to the Spanish news site.

Ruiz was recognized internationally for his study in the fields of neuropathology and anatomopatología, and devoted much of his professional life to the study of human transmissible spongiform encephalopathy.

Creutzfeldt-Jakob disease is a rare and invariably fatal brain disorder, according to the National Institute of Neurological Disorders and Stroke. There is currently no single diagnostic test for the disease. The only way to confirm a Creutzfeldt-Jakob disease diagnosis is by brain biopsy or autopsy.

Irma Linda Andablo CJD Victim, she died at 38 years old on February 6, 2010 in Mesquite Texas.



She left 6 Kids and a Husband.The Purpose of this web is to give information in Spanish to the Hispanic community, and to all the community who want's information about this terrible disease.- Physician Discharge Summary, Parkland Hospital, Dallas Texas Admit Date: 12/29/2009 Discharge Date: 1/20/2010 Attending Provider: Greenberg, Benjamin Morris; General Neurology Team: General Neurology Team Linda was a Hispanic female with no past medical history presents with 14 months of incresing/progressive altered mental status, generalized weakness, inability to walk, loss of appetite, inability to speak, tremor and bowel/blader incontinence. She was, in her usual state of health up until February, 2009, when her husbans notes that she began forgetting things like names and short term memories. He also noticed mild/vague personality changes such as increased aggression. In March, she was involved in a hit and run MVA,although she was not injured. The police tracked her down and ticketed her. At that time, her son deployed to Iraq with the Army and her husband assumed her mentation changes were due to stress over these two events. Also in March, she began to have weakness in her legs, making it difficult to walk. Over the next few months, her mentation and personality changes worsened, getting to a point where she could no longer recognized her children. She was eating less and less. She was losing more weight. In the last 2-3 months, she reached the point where she could not walk without an assist, then 1 month ago, she stopped talking, only making grunting/aggressive sounds when anyone came near her. She also became both bowel and bladder incontinent, having to wear diapers. Her '"tremor'" and body jerks worsened and her hands assumed a sort of permanent grip position, leading her family to put tennis balls in her hands to protect her fingers. The husband says that they have lived in Nebraska for the past 21 years. They had seen a doctor there during the summer time who prescribed her Seroquel and Lexapro, Thinking these were sx of a mood disorder. However, the medications did not help and she continued to deteriorate clinically. Up until about 6 years ago, the pt worked at Tyson foods where she worked on the assembly line, slaughtering cattle and preparing them for packaging. She was exposed to brain and spinal cord matter when she would euthanize the cattle. The husband says that he does not know any fellow workers with a similar illness. He also says that she did not have any preceeding illness or travel.

Comment: comment submission Document ID APHIS-2008-0010-0001 Greetings USDA, OIE et al, what a difference it makes with science, from one day to the next. i.e. that mad cow gold card the USA once held. up until that fateful day in December of 2003, the science of BSE was NO IMPORTS TO USA FROM BSE COUNTRY. what a difference a day makes$ now that the shoe is on the other foot, the USDA via the OIE, wants to change science again, just for trade $ I implore the OIE decision and policy makers, for the sake of the world, to refuse any status quo of the USA BSE risk assessment. if at al, the USA BSE GBR should be raise to BSE GBR IV, for the following reasons. North America is awash with many different TSE Prion strains, in many different species, and they are mutating and spreading. IF the OIE, and whatever policy makers, do anything but raise the risk factor for BSE in North America, they I would regard that to be highly suspicious. IN fact, it would be criminal in my opinion, because the OIE knows this, and to knowingly expose the rest of the world to this dangerous pathogen, would be ‘knowingly’ and ‘willfully’, just for the almighty dollar, once again. I warned the OIE about all this, including the risk factors for CWD, and the fact that the zoonosis potential was great, way back in 2002. THE OIE in collaboration with the USDA, made the legal trading of the atypical Nor-98 Scrapie a legal global commodity. yes, thanks to the OIE and the USDA et al, it’s now legal to trade the atypical Nor-98 Scrapie strain all around the globe. IF you let them, they will do the same thing with atypical BSE and CWD (both strains to date). This with science showing that indeed these TSE prion strains are transmissible. I strenuously urge the OIE et al to refuse any weakening to the USA trade protocols for the BSE TSE prion disease (all strains), and urge them to reclassify the USA with BSE GBR IV risk factor.

L-BSE, TME, AND SPORADIC CJD aka mad cow disease in North America



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.



Second threat

Transmissibility of BSE-L and Cattle-Adapted TME Prion Strain to Cynomolgus Macaque



Transmissibility of BSE-L and Cattle-Adapted TME Prion Strain to Cynomolgus Macaque

The epidemiology of Transmissible mink encephalopathy (TME) indicates an alimentary origin. Several inter-species transmission experiments have not succeeded in establishing with certainty any natural reservoir of this prion strain, although both ovine and bovine sources have been suspected. Cattle exposed to TME develop a spongiform encephalopathy that is distinct from classical Bovine Spongiform Encephalopathy (c-BSE).



Inoculation of c-BSE to cynomolgus macaque provided early evidence of a possible risk to humans, and remains an important model to define the risk of both primary (oral transmission from cattle to primate) and secondary (intravenous intra-species transmission) exposures. We have also evaluated the transmissibility of other cattle prion strains to macaques, including L- and H- atypical forms of BSE, namely BSE-L and BSE-H, and cattle-adapted TME.



BSE-L induced a neurological disease distinct from c-BSE. Peripheral exposures demonstrate the transmissibility of BSE-L by oral, intravenous, and intra-cerebral routes, with incubation periods similar to c-BSE. Cattle-adapted TME also induced a rapid disease in cynomolgus macaque. The clinical features, lesion profile, and biochemical signature of the induced disease was similar to the features observed in animals exposed to BSE-L, suggesting a link between the two prion strains. Secondary transmissions to a common host (transgenic mouse overexpressing bovine PrP) of cattle-TME and BSE-L before or after passage in primates induced diseases with similar incubation periods: like the c-BSE strain, these cattle strains maintained their distinctive features regardless of the donor species and passages.



If the link between TME and BSE-L is confirmed, our results would suggest that BSE-L in North America may have existed for decades, and highlight a possible preferential transmission of animal prion strains to primates after passage in cattle.

Phenotypic Similarity of Transmissible Mink Encephalopathy in Cattle and L-type Bovine Spongiform Encephalopathy in a Mouse Model

Abstract



Transmissible mink encepholapathy (TME) is a foodborne transmissible spongiform encephalopathy (TSE) of ranch-raised mink; infection with a ruminant TSE has been proposed as the cause, but the precise origin of TME is unknown. To compare the phenotypes of each TSE, bovine-passaged TME isolate and 3 distinct natural bovine spongiform encephalopathy (BSE) agents (typical BSE, H-type BSE, and L-type BSE) were inoculated into an ovine transgenic mouse line (TgOvPrP4). Transgenic mice were susceptible to infection with bovine-passaged TME, typical BSE, and L-type BSE but not to H-type BSE. Based on survival periods, brain lesions profiles, disease-associated prion protein brain distribution, and biochemical properties of protease-resistant prion protein, typical BSE had a distint phenotype in ovine transgenic mice compared to L-type BSE and bovine TME.The similar phenotypic properties of L-type BSE and bovine TME in TgOvPrP4 mice suggest that L-type BSE is a much more likely candidate for the origin of TME than is typical BSE.



snip...



Conclusion



These studies provide experimental evidence that the Stetsonville TME agent is distinct from typical BSE but has phenotypic similarities to L-type BSE in TgOvPrP4 mice. Our conclusion is that L-type BSE is a more likely candidate for a bovine source of TME infection than typical BSE. In the scenario that a ruminant TSE is the source for TME infection in mink, this would be a second example of transmission of a TSE from ruminants to non-ruminants under natural conditions or farming practices in addition to transmission of typical BSE to humans, domestic cats, and exotic zoo animals(37). The potential importance of this finding is relevant to L-type BSE, which based on experimental transmission into humanized PrP transgenic mice and macaques, suggests that L-type BSE is more pathogenic for humans than typical BSE (24,38).

Infectivity in Skeletal Muscle of Cattle with Atypical Bovine Spongiform Encephalopathy



The present data offer novel information on the tropism of the BASE agent and highlight relevant public health issues. While the transmission barrier for classical BSE is high in most species, BASE prions are readily transmissible to a variety of mammals including non-human primates [11]–[13], [35]. Accordingly, the possibility of spreading of BASE prions through skeletal muscle to other species should be taken into account and evaluated in risk analysis studies.

Saturday, February 18, 2012



Occurrence, Transmission, and Zoonotic Potential of Chronic Wasting Disease



CDC Volume 18, Number 3—March 2012



SNIP...



Long-term effects of CWD on cervid populations and ecosystems remain unclear as the disease continues to spread and prevalence increases. In captive herds, CWD might persist at high levels and lead to complete herd destruction in the absence of human culling. Epidemiologic modeling suggests the disease could have severe effects on free-ranging deer populations, depending on hunting policies and environmental persistence (8,9). CWD has been associated with large decreases in free-ranging mule deer populations in an area of high CWD prevalence (Boulder, Colorado, USA) (5).



SNIP...



Reasons for Caution There are several reasons for caution with respect to zoonotic and interspecies CWD transmission. First, there is strong evidence that distinct CWD strains exist (36). Prion strains are distinguished by varied incubation periods, clinical symptoms, PrPSc conformations, and CNS PrPSc depositions (3,32). Strains have been identified in other natural prion diseases, including scrapie, BSE, and CJD (3). Intraspecies and interspecies transmission of prions from CWD-positive deer and elk isolates resulted in identification of >2 strains of CWD in rodent models (36), indicating that CWD strains likely exist in cervids. However, nothing is currently known about natural distribution and prevalence of CWD strains. Currently, host range and pathogenicity vary with prion strain (28,37). Therefore, zoonotic potential of CWD may also vary with CWD strain. In addition, diversity in host (cervid) and target (e.g., human) genotypes further complicates definitive findings of zoonotic and interspecies transmission potentials of CWD. Intraspecies and interspecies passage of the CWD agent may also increase the risk for zoonotic CWD transmission. The CWD prion agent is undergoing serial passage naturally as the disease continues to emerge. In vitro and in vivo intraspecies transmission of the CWD agent yields PrPSc with an increased capacity to convert human PrPc to PrPSc (30). Interspecies prion transmission can alter CWD host range (38) and yield multiple novel prion strains (3,28). The potential for interspecies CWD transmission (by cohabitating mammals) will only increase as the disease spreads and CWD prions continue to be shed into the environment. This environmental passage itself may alter CWD prions or exert selective pressures on CWD strain mixtures by interactions with soil, which are known to vary with prion strain (25), or exposure to environmental or gut degradation. Given that prion disease in humans can be difficult to diagnose and the asymptomatic incubation period can last decades, continued research, epidemiologic surveillance, and caution in handling risky material remain prudent as CWD continues to spread and the opportunity for interspecies transmission increases. Otherwise, similar to what occurred in the United Kingdom after detection of variant CJD and its subsequent link to BSE, years of prevention could be lost if zoonotic transmission of CWD is subsequently identified, SNIP...SEE FULL TEXT ;

TRANSMISSION OF ALZHEIMER-TYPE PLAQUES TO PRIMATES



1. CMO will wish to be aware that a meeting was held at DH yesterday, 4 January, to discuss the above findings. It was chaired by Professor Murray (Chairman of the MRC Co-ordinating Committee on Research in the Spongiform Encephalopathies in Man), and attended by relevant experts in the fields of Neurology, Neuropathology, molecular biology, amyloid biochemistry, and the spongiform encephalopathies, and by representatives of the MRC and AFRC.



2. Briefly, the meeting agreed that:



i) Dr Ridley et als findings of experimental induction of p amyloid in primates were valid, interesting and a significant advance in the understanding of neurodegenerative disorders;



ii) there were no immediate implications for the public health, and no further safeguards were thought to be necessary at present; and



iii) additional research was desirable, both epidemiological and at the molecular level. Possible avenues are being followed up by DH and the MRC, but the details will require further discussion.

TRANSMISSION OF ALZHEIMER TYPE PLAQUES TO PRIMATES



1. Thank you for showing me Diana Dunstan's letter. I am glad that MRC have recognized the public sensitivity of these findings and intend to report them in their proper context. This hopefully will avoid misunderstanding and possible distortion by the media to portray the results as having more greater significance than the findings so far justify.



2. Using a highly unusual route of transmission (intra-cerebral injection) the researchers have demonstrated the transmission of a pathological process from two cases one of severe Alzheimer's disease the other of Gerstmann-Straussler disease to marmosets. However they have not demonstrated the transmission of either clinical condition as the "animals were behaving normally when killed'. As the report emphasizes the unanswered question is whether the disease condition would have revealed itself if the marmosets had lived longer. They are planning further research to see if the conditions, as opposed to the partial pathological process, is transmissible.



What are the implications for public health?



3. . The route of transmission is very specific and in the natural state of things highly unusual. However it could be argued that the results reveal a potential risk, in that brain tissue from these two patients has been shown to transmit a pathological process. Should therefore brain tissue from such cases be regarded as potentially infective? Pathologists, morticians, neuro surgeons and those assisting at neuro surgical procedures and others coming into contact with "raw" human brain tissue could in theory be at risk. However, on a priori grounds given the highly specific route of transmission in these experiments that risk must be negligible if the usual precautions for handling brain tissue are observed.

4. The other dimension to consider is the public reaction. To some extent the GSS case demonstrates little more than the transmission of BSE to a pig by intra-cerebral injection. If other prion diseases can be transmitted in this way it is little surprise that some pathological findings observed in GSS were also transmissible to a marmoset. But the transmission of features of Alzheimer's pathology is a different matter, given the much greater frequency of this disease and raises the unanswered question whether some cases are the result of a transmissible prion. The only tenable public line will be that "more research is required" before that hypothesis could be evaluated. The possibility on a transmissible prion remains open. In the meantime MRC needs carefully to consider the range and sequence of studies needed to follow through from the preliminary observations in these two cases. Not a particularly comfortable message, but until we know more about the causation of Alzheimer's disease the total reassurance is not practical.
