Idaho probes possible CJD deaths

Dave Wilkins
Idaho Staff Writer

Idaho health officials this week ruled out Creutzfeldt-Jakob Disease as the cause of death of one woman, but are still investigating four other possible cases.

Since January, five women 60 years of age and older have died after being diagnosed with the rare neurodegenerative disorder.

Autopsies were performed on three of the women and brain tissue samples submitted to a national laboratory.

Prelminary results have come back for two of the three. One confirmed that the woman died of a prion disease, while the other was negative, health officials said this week.

Four of the women lived in Twin Falls County, and one lived in nearby Minidoka County. A man in Elmore County has also been diagnosed with the disease and is still alive, health officials said this week.

To have five suspected cases of CJD in one rural area in such a short time is unusual.

On average, Idaho has had only about one CJD death per year.

“The most we have ever had in the whole state is three in any year going back to 1984,” said Tom Shanahan, a spokesman for the Idaho Department of Health and Welfare.

Authorities became concerned when the number of diagnosed cases in the Magic Valley began rising this year, Shanahan said.

The state health department has launched an investigation, including interviews with doctors, examination of medical records and a survey of victims’ families.

The survey includes questions about lifestyle and diet – whether the victims ate beef, chicken, pork or wild game – for instance.

“We’ve also looked at their occupations and environmental factors,” Shanahan said. “We’re compiling all that in a database to see if there are any similarities.”

So far, however, “nothing has jumped out,” he said.

CJD progresses rapidly and is always fatal.

An examination of brain tissue is the only way to confirm the presence of CJD.

Officials are awaiting final test results from Case Western Reserve University in Cleveland. They won’t know until they get them back whether the deaths were indeed from CJD.

For now, authorities believe the likely cause of death was a classic form of CJD that occurs sporadically, caused by the spontaneous transformation of normal prion proteins into abnormal prions.

Health officials said there’s little chance the deaths could be linked to variant CJD, which is related to BSE or “mad cow” disease.

There has never been a confirmed case of variant CJD in the United States. In England, which has had several cases, the victims have been much younger – about 27 to 28 years of age – on average.

“If it turns out to be CJD, we think it probably will be the sporadic form,” Shanahan said of the Idaho cases.

Sporadic CJD strikes about one in every 1 million people. About 280 cases are reported in the United States every year.

There have been other clusters of sporadic CJD cases elsewhere in the country without any definitive causes, Shanahan said.

“They have never been able to point at something specific that has caused it,” he said. “I don’t know whether we’re going to find any answers.”

right, 85%+ of all CJD 'sporadic' in the USA is just spontaneous and there are no mad cows in the USA (if it would have been left up to Johann et al at USDA that Texas cow would have stayed negative). total BSeee.

-0000 From: "Asante, Emmanuel A" To:

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
