Suspect case of Creutzfeldt-Jakob disease investigated in Brazil

brain disease Brazil Creutzfeldt-Jakob disease Latin America and the Caribbean prion prion disease transmissible spongiform encephalopathies

The death of a 70-year-old man from Belo Horizonte, Brazil is being investigated by health authorities as possibly being caused by the prion disease, Creutzfeldt-Jakob disease (CJD), according to a Wall Street Journal report Tuesday.

According to the report, tissue samples are currently be analyzed to determine if the cause of death was CJD. Last year, health officials in the city investigated four other suspect cases; however, all tested negative for CJD.

Creutzfeldt-Jakob disease (CJD) is a rare and fatal disease that affects the nervous system and causes deterioration of the brain. It affects about one in a million people each year worldwide. In the United States, only about 200 people are diagnosed with CJD each year.

In the early stages of CJD, the patient may have rapidly failing memory and other cognitive difficulties. These symptoms become worse much faster than with other more common types of dementia, such as Alzheimer’s disease. Other symptoms can include personality changes including anxiety and depression, lack of coordination, and visual disturbances. As the illness progresses, mental deterioration becomes pronounced and involuntary movements such as sudden jerky movements, blindness, weakness of extremities, and coma may occur. There is no treatment or cure.

makes you wonder who’s doing the testing, and what test are being used ???

Molecular Barriers to Zoonotic Transmission of Prions

*** chronic wasting disease, there was no absolute barrier to conversion of the human prion protein.

*** Furthermore, the form of human PrPres produced in this in vitro assay when seeded with CWD, resembles that found in the most common human prion disease, namely sCJD of the MM1 subtype.

Subtype 1: (sCJDMM1 and sCJDMV1)

This subtype is observed in patients who are MM homozygous or MV heterozygous at codon 129 of the PrP gene (PRNP) and carry PrPSc Type 1. Clinical duration is short, 3‑4 months.32 The most common presentation in sCJDMM1 patients is cognitive impairment leading to frank dementia, gait or limb ataxia, myoclonic jerks and visual signs leading to cortical blindness (Heidenhain’s syndrome)...

Animals injected with iatrogenic Creutzfeldt–Jakob disease MM1 and genetic Creutzfeldt–Jakob disease MM1 linked to the E200K mutation showed the same phenotypic features as those infected with sporadic Creutzfeldt–Jakob disease MM1 prions...

http://brain.oxfordjournals.org/content/early/2010/09/07/brain.awq234.full.pdf

*** our results raise the possibility that CJD cases classified as VV1 may include cases caused by iatrogenic transmission of sCJD-MM1 prions or food-borne infection by type 1 prions from animals, e.g., chronic wasting disease prions in cervid. In fact, two CJD-VV1 patients who hunted deer or consumed venison have been reported (40, 41). The results of the present study emphasize the need for traceback studies and careful re-examination of the biochemical properties of sCJD-VV1 prions. ***
