Organ distribution of prion proteins in variant Creutzfeldt-Jakob disease
Original Text

Summary
In this article we give an overview of the transmissible spongiform encephalopathies, with emphasis on the evidence for the distribution of abnormal prions in tissues. The normal prion protein is distributed ubiquitously throughout human body tissues. Endogenous expression of the normal prion protein, as well as auxiliary proteins, plays a part in accumulation of the abnormal prion protein. As exemplified by variant Creutzfeldt-Jakob disease (vCJD) the abnormal prion protein can accumulate in the host lymphoid system, in particular the follicular dendritic cells. The route for the disease-related prion neuroinvasion is likely to involve the peripheral nervous system. An alternative route may involve blood constituents. Both animal studies and studies on vCJD patients suggest a potential for abnormal prion distribution in several peripheral tissues other than the lymphoreticular system. In human beings the abnormal prion has been reported in the brain, tonsils, spleen, lymph node, retina, and proximal optic nerve. Infectivity, although present in peripheral tissues, is at lower levels than in the central nervous system (CNS). Animal models suggest that the growth of infectivity in the CNS is likely to be gradual with maximum values during the clinical phase of disease. That tissues may harbour the abnormal prion, at different levels of infectivity, during the incubation period of the disease raises concerns of iatrogenic transmission of the disease either after surgery, blood transfusion, or accidental organ transplantation from donors in the preclinical phase of the disease.

Cadaver corneal transplants -- without family permission
Houston, Texas channel 11 news 28 Nov 99
Reported by Terry S. Singeltary Sr. son of CJD victim
"It was a story about how the Lions eye bank were harvesting corneas from victims in the Morgue, without their consent. Under Texas law, this appears to be legal (remember Texas has the Veggie liable law). Even if Family says no, this appears to happen, from what the news story said. They said the only way to prevent this, is to fill out a form, stating not to have this done. So if you don't fill out the form, they can do this. How many people don't know about the form?
This is not only disgusting and appalling, it could be highly infectious. Without proper background checking of the donors, on their physical history, checking on past dementia, and/or family history, some of these unfortunate victims, could be passing a human TSE.
Response Jill Spitler Clevelland Eye Bank:
"No, we are not stealing.........Yes, you do have such a law in the state of Texas, but not all your state Eye Banks utilize the law. The Eye Bank that you're speaking of is only one of 43 certified Eye Bank throughout the USA.
And there are measure taken per the Medical Standards of the Eye Bank Association of America, the certifying body for eye banks and per FDA regulations to address those concerns that you speak of.
I would suggest that those interested/concern with transplant contact their local agencies. The Eye Bank Association of America has a web. site . Further if anyone has problems contacting or finding out about their local organization(s), call me or e-mail me I would be glad to help. My e-mail address is jill@clevelandeyebank.org"
Terry Singeltary responds:
"Explain this to the family in Houston who went to their loved ones funeral, only to find out that the loved one that was in the casket, had their corneas removed without their permission, without the consent of the victim or it's family. They would not have known it, only for the funny look the victim had. So, they questioned, only to find out, the corneas, had in fact, been removed without consent.
I call that stealing, regardless what the law states. This type of legal grave robbing is not a logical thing to do without knowing any type of background of the victims medical past, which really will not prove anything due to the incubation period. Eye tissue being potentially a highly infective source, there are risks here.
Should they not at least know of the potential ramifications of TSE's (the person receiving the corneas)?
Should there not be some sort of screening?
Should there be some sort of moral issue here? If this is the case, and in fact, they can come take your corneas, without your consent, then what will they start taking next, without your consent?
Lets look at a hypothetical situation: What would happen if my Mom (DOD 12-14-97 hvCJD) would have gotten into a car wreck and died, before the symptoms of CJD appeared. Not much money, so there was no autopsy. What would have happened to that recipient of those infecting corneas?"
Comment (webmaster): Actual transmission of CJD by means of corneal transplant may or may not be rare. The incidence of infectivity in older people could be fairly high; this is not to be confused with the lower incidence of symptomatic (clinical) CJD. It is very unlikely that familial CJD would have been diagnosed in earlier generations; however, without interviewing the family even known kindreds would not be excluded.
In blood donation, a much stricter policy is followed, even though corneal transplant may be far more dangerous (being a direct link to the brain and not going through purification steps).
Since highly sensitive tests for pre-clinical CJD are now available, it would make sense to screen corneas for CJD, just as they are screened for AIDS, hepatitus, and a host of other conditions.

URGENT DATA ON ATYPICAL BSE RISK FACTORS TO HUMANS AND ANIMALS OIE REFUSE TO ACKNOWLEDGE $

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.

I look forward to further transmission studies, and a true ENHANCED BSE/atypical BSE surveillance program put forth testing all cattle for human and animal consumption for 5 years. a surveillance program that uses the most sensitive TSE testing, and has the personnel that knows how to use them, and can be trusted. I look forward to a stringent mad cow feed ban being put forth, and then strictly enforced. we need a forced, not voluntary feed ban, an enhanced feed ban at that, especially excluding blood. we need some sort of animal traceability. no more excuses about privacy. if somebody is putting out a product that is killing folks and or has the potential to kill you, then everybody needs to know who they are, and where that product came from. same with hospitals, i think medical incidents in all states should be recorded, and made public, when it comes to something like a potential accidental transmission exposure event. so if someone is out there looking at a place to go have surgery done, if you have several hospitals having these type 'accidental exposure events', than you can go some place else. it only makes sense. somewhere along the road, the consumer lost control, and just had to take whatever they were given, and then charged these astronomical prices. some where along the line the consumer just lost interest, especially on a long incubating disease such as mad cow disease i.e. Transmissible Spongiform Encephalopathy. like i said before, there is much more to the mad cow story than bovines and eating a hamburger, we must start focusing on all TSE in all species. ...TSS

I look forward to a stringent mad cow feed ban being put forth, and then strictly enforced. we need a forced, not voluntary feed ban, an enhanced feed ban at that, especially excluding blood. we need some sort of animal traceability. no more excuses about privacy. if somebody is putting out a product that is killing folks and or has the potential to kill you, then everybody needs to know who they are, and where that product came from. same with hospitals, i think medical incidents in all states should be recorded, and made public, when it comes to something like a potential accidental transmission exposure event. so if someone is out there looking at a place to go have surgery done, if you have several hospitals having these type 'accidental exposure events', than you can go some place else. it only makes sense. somewhere along the road, the consumer lost control, and just had to take whatever they were given, and then charged these astronomical prices. some where along the line the consumer just lost interest, especially on a long incubating disease such as mad cow disease i.e. Transmissible Spongiform Encephalopathy. like i said before, there is much more to the mad cow story than bovines and eating a hamburger, we must start focusing on all TSE in all species. ...TSS
