ITALY REPORTING INCREASE IN CASES OF MAD COW TYPE TSE PRION DISEASE IN HUMANS CJD

'Mad cow' fears after man dies in Turin

An investigation has been opened after a man died from suspected 'mad cow' disease in Turin last week.

 

Francesco Catapano, a 53 year old from Ottaviano near Naples, was hospitalized in Turin in June and was later diagnosed with Creutzfeldt-Jakob Disease, otherwise known as 'mad cow”disease.

 

He died on September 1st at Turin's Molinette hospital.

 

The illness causes the brain tissue to deteriorate rapidly, resulting in death, usually within months.

 

It became notorious in the 1990s after an outbreak was attributed to eating infected meat and dubbed 'mad cow' disease by the media.

 

Only one form of the disease, variant CJD, is due to eating contaminated food, but officials believe this could be the cause of Catapano's death.

 

“Genetic predisposition was not revealed during early exams and some of the results from the diagnostic procedure suggest that the case may be down to contaminated food,” Antonio Scarmozzino, health director at Molinette hospital, told La Stampa.

 

Cases of variant CJD can only be determined via an autopsy carried out on cerebral tissue post-mortem.

 

However, the testing process is slow as it requires that tissue samples are kept under a formalin solution before testing.

 

Ahead of the autopsy results in October, magistrate Raffaele Guariniello has asked Italy's health police, Nas, to analyze Catapano's medical records.

 

Even if the case is shown to be down to eating contaminated food, it will be impossible to determine the source as the disease can have incubation periods of up to 20 years.

 

Italy has only ever seen two deaths from variant CJD and has one of the lowest incidences of the disease in the EU. But the alarm was raised in August when two people died of CJD in Puglia in the same week.

 

The last recorded case of the disease in an Italian cow was in 2011.

 


 

Two dead from 'mad cow' disease in Lecce Patrick Browne · 6 Aug 2015, 10:36

 

Published: 06 Aug 2015 10:36 GMT+02:00

 

A 67-year-old man died of 'mad cow' disease earlier this week at his home in Lecce - the second death caused by the disease in the Puglia province this week.

 

The man was diagnosed on July 10th, after he fainted.

 

His death comes after the illness claimed the life of a 49-year old woman in the nearby town of Casarano on Saturday, and is the fourth case of the disease to hit the province of Lecce, part of the Salento area, this year.

 

Known officially as Creutzfeldt-Jakob Disease (CJD), the disease became notorious in the 1990s after an outbreak was attributed to eating infected meat. It was dubbed 'mad cow' disease by the media.

 

The illness causes the brain tissue to deteriorate rapidly, resulting in death, usually within months.

 

But it can have many causes and is not only due to eating meat contaminated with the disease.

 

Giovanni Gorgoni, the general manager of the local health authority, moved quickly to quell fears that infected meat had caused the outbreak.

 

“Until today, no cases of the disease caused by eating infected meat have been recorded in Salento,” he told Leccepirma.it.

 

“The strict protocols for tracing and checking meat that were brought in following the epidemic in Britain reassure us that this will continue to be the case.”

 

Samples of the deceased patients' cerebral tissue have been sent for analysis in Bologna to establish which form of CJD they were infected with.

 

Only one form of the disease, variant CJD, is caused by eating contaminated food and 10 to 15 percent of all cases are genetic.

First case of vCJD reported in Italy

 

The first case of variant Creutzfeld-Jakob Disease (vCJD) has been reported in Italy (1). The case from Sicily was diagnosed in Italy and Great Britain on the basis of clinical and instrumental tests and tonsillar biopsy. The Istituto Superiore di Sanità (ISS) has classified the case as probable, but since the patient is still alive, the ISS has not released any additional information. The surveillance and reporting of CJD has been mandatory in Italy since the beginning of 2002. A ban on feeding mammalian protein to ruminants was approved on 28 July 1984, and enforced from 15 September that year. The prevalence of indigenous cases of bovine spongiform encephalopathy per 10 000 tests was 1.03 for the year 2001 (2).

First case of variant Creutzfeldt-Jakob disease reported in Italy - update

 

A paper published in the Lancet this week describes the first case of variant Creutzfeldt-Jakob disease (vCJD) in Italy (1). The patient, a 25 year old Sicilian woman, developed clinical symptoms in 2001 and was first reported in February this year (2). Although definitive diagnosis of vCJD requires neuropathological confirmation, the woman’s illness fulfils the diagnostic criteria for probable vCJD (3), a brain scan was characteristic of vCJD and the abnormal protein associated with vCJD has been detected in a tonsil biopsy.

 

The patient had never undergone neurosurgery, or received a blood transfusion or any other treatment that might be associated with transmission of a prion disease. Scientific evidence suggests that vCJD is, however, caused by transmission of the bovine spongiform encephalopathy agent (BSE) to humans. The woman is likely to have acquired her infection within Italy, having never travelled to the United Kingdom (UK) or any other country with reported BSE. Cases of indigenous BSE were first reported in Italy following the implementation, in 2001, of mandatory testing of cattle older than 30 months destined for slaughter (4). By the end of September 2002 70 indigenous cases and two British imported cases had been identified (5).

 

To date, in addition to the Italian case, single cases of definite or probable vCJD have been diagnosed with onset in each of the Republic of Ireland, Canada and the United States, a further six in France and 127 in the UK (see EUROCJD, http://www.eurocjd.ed.ac.uk/). The occurrence of cases both within and outside the UK remains a concern, supporting the need for continuous surveillance programmes of transmissible spongiform encephalopathies in humans and animals in the UK and other countries.

In October 1998 the simultaneous occurrence of spongiform encephalopathy in a man and his pet cat was reported.

 

The report from Italy noted that the cat did not display the same clinical features as FSE cases previously seen. Indeed, the presence of a new type of FSE was suggested. The man was diagnosed as having sporadic CJD, and neither case (man nor cat) appeared to be affected by a BSE-related condition.

Transmissible spongiform encephalopathies (TSE) encompass inherited,acquired, and sporadic mammalian neurological disorders, and are characterised by the conversion of the cellular prion protein (PrP) in an insoluble and protease-resistant isoform (PrPres). In human TSE, four types of PrPres have been identified according to size and glycoform ratios, which may represent different prion strains. Type-1 and type-2 PrPres are associated with sporadic Creutzfeldt-Jakob disease (CJD), type 3 with iatrogenic CJD, and type 4 with variant CJD.1,2 There is evidence that variant CJD is caused by the bovine spongiform encephalopathy (BSE)-prion strain.2-4 The BSE strain has been identified in three cats with feline spongiform encephalopathy (FSE), a prion disease which appeared in 1990 inthe UK.5

 

We report the simultaneous occurrence of sporadic CJD in a man and a new variety of FSE in his cat.

Evidence of a new type of FSE was further provided by the detection of a type-1 PrPres, other than the BSE-associated type 4.2

Italy: Two More Cases BSE Confirmed

 

ROME (AP) - Italy confirmed two more cases of mad cow disease Tuesday, bringing the total number of infected animals to nine.

 

Another suspected case in central Italy awaits final results.

 

The infected cows were found in two separate farms in the northern Lombardy region, said the Health Ministry.

 

Final analyses of the brain tissue were conducted in a Turin-based zoological institute.

 

Italy has tested more than 54,500 animals since the beginning of the year, when the European Union began requiring tests on cattle older than 30 months destined for slaughter. About 1,000 tests await final results, the Health Ministry said.

 

Many experts believe that bovine spongiform encephalopathy, the formal name for mad cow disease, can be transmitted to people who eat meat from infected animals.

 

So far, Italy has had no human cases.

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 longe incubation than BSE. ***Scrapie, as recently evoked in humanized mice (Cassard, 2014), is the third potentially zoonotic PD (with BSE and L-type BSE), ***thus questioning the origin of human sporadic cases. We will present an updated panorama of our different transmission studies and discuss the implications of such extended incubation periods on risk assessment of animal PD for human health.

P.86: Estimating the risk of transmission of BSE and scrapie to ruminants and humans by protein misfolding cyclic amplification

 

Morikazu Imamura, Naoko Tabeta, Yoshifumi Iwamaru, and Yuichi Murayama National Institute of Animal Health; Tsukuba, Japan

 

To assess the risk of the transmission of ruminant prions to ruminants and humans at the molecular level, we investigated the ability of abnormal prion protein (PrPSc) of typical and atypical BSEs (L-type and H-type) and typical scrapie to convert normal prion protein (PrPC) from bovine, ovine, and human to proteinase K-resistant PrPSc-like form (PrPres) using serial protein misfolding cyclic amplification (PMCA).

 

Six rounds of serial PMCA was performed using 10% brain homogenates from transgenic mice expressing bovine, ovine or human PrPC in combination with PrPSc seed from typical and atypical BSE- or typical scrapie-infected brain homogenates from native host species. In the conventional PMCA, the conversion of PrPC to PrPres was observed only when the species of PrPC source and PrPSc seed matched. However, in the PMCA with supplements (digitonin, synthetic polyA and heparin), both bovine and ovine PrPC were converted by PrPSc from all tested prion strains. On the other hand, human PrPC was converted by PrPSc from typical and H-type BSE in this PMCA condition.

 

Although these results were not compatible with the previous reports describing the lack of transmissibility of H-type BSE to ovine and human transgenic mice, ***our findings suggest that possible transmission risk of H-type BSE to sheep and human. Bioassay will be required to determine whether the PMCA products are infectious to these animals.

CHAIR—Welcome. Would you like to make an opening statement?

 

Mr Bellinger—Thank you. The ABA stands by its submission, which we made on 14

 

December last year, that the decision made by the government to allow the importation of beef from BSE affected countries is politically based, not science based. During this hearing we will bring forward compelling new evidence to back up this statement. When I returned to my property after the December hearing I received a note from an American citizen. I will read a small excerpt from the mail he sent me in order to reinforce the dangers of allowing the importation of beef from BSE affected countries. I have done a number of press releases on this topic, and this fellow has obviously picked my details up from the internet. His name is Terry Singeltary and he is from Bacliff, Texas. He states, and rightfully so:

 

snip...end

 

*** Singeltary reply ; Molecular, Biochemical and Genetic Characteristics of BSE in Canada Singeltary reply ;

 


 

We have shown that cattle-adapted TME is the third cattle prion strain (joining classical and L-type BSE) to be transmissible both to non-human primates and transgenic mice overexpressing human PrP. However, the successful transmission of raccoon TME to primate, inducing a disease with similar features as cattle TME, extends this notion to TME-related strains independent of host origin. Pathological, biochemical and bioassay investigations converged to demonstrate the similarity between cattle-adapted TME and L-BSE.

 


 

I strenuously once again urge the FDA and its industry constituents, to make it MANDATORY that all ruminant feed be banned to all ruminants, and this should include all cervids as soon as possible for the following reasons...

 

======

 

In the USA, under the Food and Drug Administrations BSE Feed Regulation (21 CFR 589.2000) most material (exceptions include milk, tallow, and gelatin) from deer and elk is prohibited for use in feed for ruminant animals. With regards to feed for non-ruminant animals, under FDA law, CWD positive deer may not be used for any animal feed or feed ingredients. For elk and deer considered at high risk for CWD, the FDA recommends that these animals do not enter the animal feed system.

 

***However, this recommendation is guidance and not a requirement by law.

Dietary Risk Factors for Sporadic Creutzfeldt-Jakob Disease: A Confirmatory Case-Control Study

 

Conclusions—The a priori hypotheses were supported.

 

*Consumption of various meat products may be one method of transmission of the infectious agent for sCJD.

 


 

Pathological Prion Protein (PrPTSE) in Skeletal Muscles of Farmed and Free Ranging White-Tailed Deer Infected with Chronic Wasting Disease

 

***The presence and seeding activity of PrPTSE in skeletal muscle from CWD-infected cervids suggests prevention of such tissue in the human diet as a precautionary measure for food safety, pending on further clarification of whether CWD may be transmissible to humans.

 


 

*** PPo3-7: Prion Transmission from Cervids to Humans is Strain-dependent

 

*** Here we report that a human prion strain that had adopted the cervid prion protein (PrP) sequence through passage in cervidized transgenic mice efficiently infected transgenic mice expressing human PrP,

 

*** indicating that the species barrier from cervid to humans is prion strain-dependent and humans can be vulnerable to novel cervid prion strains.

 

PPo2-27:

 

Generation of a Novel form of Human PrPSc by Inter-species Transmission of Cervid Prions

 

*** Our findings suggest that CWD prions have the capability to infect humans, and that this ability depends on CWD strain adaptation, implying that the risk for human health progressively increases with the spread of CWD among cervids.

 

PPo2-7:

 

Biochemical and Biophysical Characterization of Different CWD Isolates

 

*** The data presented here substantiate and expand previous reports on the existence of different CWD strains.

*** These results would seem to suggest that CWD does indeed have zoonotic potential, at least as judged by the compatibility of CWD prions and their human PrPC target. Furthermore, extrapolation from this simple in vitro assay suggests that if zoonotic CWD occurred, it would most likely effect those of the PRNP codon 129-MM genotype and that the PrPres type would be similar to that found in the most common subtype of sCJD (MM1).***

BSE prions propagate as either variant CJD-like or sporadic CJD-like prion strains in transgenic mice expressing human prion protein

 

*** Surprisingly, however, BSE transmission to these transgenic mice, in addition to producing a vCJD-like phenotype, can also result in a distinct molecular phenotype that is indistinguishable from that of sporadic CJD with PrPSc type 2.

 

These data suggest that more than one BSEderived prion strain might infect humans;

 

***it is therefore possible that some patients with a phenotype consistent with sporadic CJD may have a disease arising from BSE exposure.

 

snip...

 

These studies further strengthen the evidence that vCJD is caused by a BSE-like prion strain.

 

Also, remarkably, the key neuropathological hallmark of vCJD, the presence of abundant florid PrP plaques, can be recapitulated on BSE or vCJD transmission to these mice.

 

***However, the most surprising aspect of the studies was the finding that an alternate pattern of disease can be induced in 129MM Tg35 mice from primary transmission of BSE, with a molecular phenotype indistinguishable from that of a subtype of sporadic CJD. This finding has important potential implications as it raises the possibility that some humans infected with BSE prions may develop a clinical disease indistinguishable from classical CJD associated with type 2 PrPSc. This is, in our experience, the commonest molecular sub-type of sporadic CJD. In this regard, it is of interest that the reported incidence of sporadic CJD has risen in the UK since the 1970s (Cousens et al., 1997)...

Dear Terry,

 

I have been asked by Professor Collinge to respond to your request. I am a Senior Scientist in the MRC Prion Unit and the lead author on the paper. I have attached a pdf copy of the paper for your attention.

 

Thank you for your interest in the paper.

 

In respect of your first question, the simple answer is, ***yes. As you will find in the paper, we have managed to associate the alternate phenotype to type 2 PrPSc, the commonest sporadic CJD. It is too early to be able to claim any further sub-classification in respect of Heidenhain variant CJD or Vicky Rimmer's version. It will take further studies, which are on-going, to establish if there are sub-types to our initial finding which we are now reporting. The main point of the paper is that, as well as leading to the expected new variant CJD phenotype, BSE transmission to the 129-methionine genotype can lead to an alternate phenotype which is indistinguishable from type 2 PrPSc.

 

I hope reading the paper will enlighten you more on the subject. If I can be of any further assistance please to not hesitate to ask. Best wishes.

 

Emmanuel Asante

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

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.

Transmissible spongiform encephalopathies (TSEs), or prion diseases, are mammalian neurodegenerative disorders characterized by a posttranslational conversion and brain accumulation of an insoluble, protease-resistant isoform (PrPSc) of the host-encoded cellular prion protein (PrPC). Human and animal TSE agents exist as different phenotypes that can be biochemically differentiated on the basis of the molecular mass of the protease-resistant PrPSc fragments and the degree of glycosylation. Epidemiological, molecular, and transmission studies strongly suggest that the single strain of agent responsible for bovine spongiform encephalopathy (BSE) has infected humans, causing variant Creutzfeldt-Jakob disease. The unprecedented biological properties of the BSE agent, which circumvents the so-called "species barrier" between cattle and humans and adapts to different mammalian species, has raised considerable concern for human health. To date, it is unknown whether more than one strain might be responsible for cattle TSE or whether the BSE agent undergoes phenotypic variation after natural transmission. Here we provide evidence of a second cattle TSE. The disorder was pathologically characterized by the presence of PrP-immunopositive amyloid plaques, as opposed to the lack of amyloid deposition in typical BSE cases, and by a different pattern of regional distribution and topology of brain PrPSc accumulation. In addition, Western blot analysis showed a PrPSc type with predominance of the low molecular mass glycoform and a protease-resistant fragment of lower molecular mass than BSE-PrPSc. Strikingly, the molecular signature of this previously undescribed bovine PrPSc was similar to that encountered in a distinct subtype of sporadic Creutzfeldt-Jakob disease.

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.
