CASE REPORTS CREUTZFELDT-JAKOB DISEASE: AN UNDER-RECOGNIZED CAUSE OF DEMENTIA

CASE REPORTS CREUTZFELDT-JAKOB DISEASE: AN UNDER-RECOGNIZED CAUSE OF DEMENTIA
To the Editor: Creutzfeldt-Jakob disease (CJD) is a progressive neurodegenerative condition with negative prognosis caused by an isoform of the prion protein.1,2 Partly because of its low prevalence, physicians often neglect it in the differential diagnosis of cognitive decline and as possible cause of dementia in older persons. CJD is usually characterized by rapidly progressive impairment of cognitive function associated with myoclonus, pyramidal, and extrapyramidal dysfunction; cerebellar and visual disturbances; akinetic mutism, or any combination of these. This report presents a paradigmatic case of CJD recently diagnosed at the Department of Geriatrics, University Hospital Agostino Gemelli (Rome, Italy).
CASE REPORT A 72-year-old man was admitted to the Geriatric Acute Care Unit in September 2009 because of rapid cognitive decline (characterized by confusion, memory impairment, and visual hallucinations) that had started suddenly the previous month. He had been previously admitted to two other hospitals for these symptoms. He had been hastily discharged from both with a primary diagnosis of “Alzheimer’s disease” and referred to specific outpatient clinics. Upon admission, he was unable to walk without assistance and showed behavioral disorders (irritability, mood swings, psychomotor agitation). He had congestive heart failure, chronic atrial fibrillation, chronic obstructive pulmonary disease, and obesity. He had also had a heart pacemaker VVI implanted 2 years before for sick sinus syndrome. Routine blood tests and urinalysis were substantially within normal ranges. He underwent two serial electroencephalograms (EEGs), which detected periodic sharp wave complexes. Because magnetic resonance imaging could not be done because of his pacemaker, a head computed tomography (CT) scan was performed, revealing abnormal density signaling in the white matter (in particular at the subcortical region and semioval center) with slight dilatation of ventricles. Myoclonus, rigidity, postural instability with cerebellar ataxia, pyramidal and extrapyramidal signs, and speech disorders progressively appeared during the first days of his hospital stay. He subsequently developed a hypokinetic, mute state and cortical blindness. Lumbar puncture could not be performed because of the rapid deterioration of his clinical condition and also considering the presence of the spikes in the EEGs. He died from pneumonia 4 months after the onset of cognitive decline. Upon autopsy, macroscopic examination revealed moderate cortical atrophy of the brain. Histological examination showed spongiform degeneration, neuronal loss and astroglial proliferation (Figure 1A). Immunohistochemical examination showed the presence of abnormal deposits of prion protein (Figure 1B). Alzheimer’s disease–type pathology with early signs of beta-amyloid deposits was also observed.
DISCUSSION By sharing common features with other dementia types3–7 and being rare8 (with an incidence rate estimated as one to two cases per million people per year), CJD can easily be missed or misdiagnosed. The diagnosis of CJD is based on clinical and instrumental (EEG, cerebrospinal fluid, magnetic resonance imaging) parameters,9 but special attention is required to make a correct diagnosis. A definite diagnosis requires neuropathological demonstration of the presence of the prion protein. In the current case, the presence of CJD was determined by comprehensively assessing the patient and building up the diagnosis based on the presence of rapid cognitive decline and neurological features. These elements were all present (to differing extents) at the previous in-hospital evaluations the patient received for the same condition, but his condition was too quickly labeled as “Alzheimer’s disease.” Moreover, the EEG was a useful diagnostic tool to validate the clinical hypothesis. It could be argued that reaching the correct diagnosis did not change the history of the patient, but the determination of the likely etiology of dementia is important in establishing the prognosis and management of the patient.10 Although no known treatment is currently available for CJD, an earlier diagnosis might have allowed a more-suitable allocation of the patient to a second-level healthcare facility better designed to respond to his needs.
Therefore, diagnostic suspicion of CJD should always be considered (regardless of age) in any patient presenting with rapidly progressive dementia, especially if associated with other neurological signs (pyramidal, extra-pyramidal, or cerebellar). The present case emphasizes the need to carefully and comprehensively approach the differential diagnosis of dementia to avoid incorrect diagnoses that may merely increase the burden of the disease on a patient and his or her relatives. A prompt and correct diagnosis may then allow the optimal allocation of the patient to the proper clinical setting. Finally, potentiating of facilities and resources able to take care of older adults rapidly and efficiently after their in-hospital stay is crucial in an aging society.

Diagnosis and Reporting of Creutzfeldt-Jakob Disease

KEYWORDS: creutzfeldt-jakob disease, diagnosis.
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.

RE-Monitoring the occurrence of emerging forms of Creutzfeldt-Jakob disease in the United States
Terry S. Singeltary, retired (medically)
I lost my mother to hvCJD (Heidenhain Variant CJD). I would like to comment on the CDC's attempts to monitor the occurrence of emerging forms of CJD. Asante, Collinge et al [1] have reported that BSE transmission to the 129-methionine genotype can lead to an alternate phenotype that is indistinguishable from type 2 PrPSc, the commonest sporadic CJD. However, CJD and all human TSEs are not reportable nationally. CJD and all human TSEs must be made reportable in every state and internationally. I hope that the CDC does not continue to expect us to still believe that the 85%+ of all CJD cases which are sporadic are all spontaneous, without route/source. We have many TSEs in the USA in both animal and man. CWD in deer/elk is spreading rapidly and CWD does transmit to mink, ferret, cattle, and squirrel monkey by intracerebral inoculation. With the known incubation periods in other TSEs, oral transmission studies of CWD may take much longer. Every victim/family of CJD/TSEs should be asked about route and source of this agent. To prolong this will only spread the agent and needlessly expose others. In light of the findings of Asante and Collinge et al, there should be drastic measures to safeguard the medical and surgical arena from sporadic CJDs and all human TSEs. I only ponder how many sporadic CJDs in the USA are type 2 PrPSc?

Laying Odds
Are prion diseases more prevalent than we thought?
Researchers and government officials badly underestimated the threat that mad cow disease posed when it first appeared in Britain. They didn't think bovine spongiform encephalopathy was a zoonosis-an animal disease that can sicken people. The 1996 news that BSE could infect humans with a new form of Creutzfeldt-Jakob disease stunned the world. It also got some biomedical researchers wondering whether sporadic CJD may really be a manifestation of a zoonotic sickness. Might it be caused by the ingestion of prions, as variant CJD is?
Revisiting Sporadic CJD
It's not hard to get Terry Singeltary going. "I have my conspiracy theories," admitted the 49-year-old Texan.1 Singeltary is probably the nation's most relentless consumer advocate when it comes to issues in prion diseases. He has helped families learn about the sickness and coordinated efforts with support groups such as CJD Voice and the CJD Foundation. He has also connected with others who are critical of the American way of handling the threat of prion diseases. Such critics include Consumers Union's Michael Hansen, journalist John Stauber, and Thomas Pringle, who used to run the voluminous www.madcow. org Web site. These three lend their expertise to newspaper and magazine stories about prion diseases, and they usually argue that prions represent more of a threat than people realize, and that the government has responded poorly to the dangers because it is more concerned about protecting the beef industry than people's health.
Singeltary has similar inclinations. ...

Transmissible Spongiform encephalopathy (TSE) animal and human TSE in North America update October 2009
T. Singeltary
Bacliff, TX, USA
Background:
An update on atypical BSE and other TSE in North America. Please remember, the typical U.K. c-BSE, the atypical l-BSE (BASE), and h-BSE have all been documented in North America, along with the typical scrapie's, and atypical Nor-98 Scrapie, and to date, 2 different strains of CWD, and also TME. All these TSE in different species have been rendered and fed to food producing animals for humans and animals in North America (TSE in cats and dogs ?), and that the trading of these TSEs via animals and products via the USA and Canada has been immense over the years, decades.
Methods:
12 years independent research of available data
Results:
I propose that the current diagnostic criteria for human TSEs only enhances and helps the spreading of human TSE from the continued belief of the UKBSEnvCJD only theory in 2009. With all the science to date refuting it, to continue to validate this old myth, will only spread this TSE agent through a multitude of potential routes and sources i.e. consumption, medical i.e., surgical, blood, dental, endoscopy, optical, nutritional supplements, cosmetics etc.
Conclusion:
I would like to submit a review of past CJD surveillance in the USA, and the urgent need to make all human TSE in the USA a reportable disease, in every state, of every age group, and to make this mandatory immediately without further delay. The ramifications of not doing so will only allow this agent to spread further in the medical, dental, surgical arena's. Restricting the reporting of CJD and or any human TSE is NOT scientific. Iatrogenic CJD knows NO age group, TSE knows no boundaries. I propose as with Aguzzi, Asante, Collinge, Caughey, Deslys, Dormont, Gibbs, Gajdusek, Ironside, Manuelidis, Marsh, et al and many more, that the world of TSE Transmissible Spongiform Encephalopathy is far from an exact science, but there is enough proven science to date that this myth should be put to rest once and for all, and that we move forward with a new classification for human and animal TSE that would properly identify the infected species, the source species, and then the route.

seems the sites showing the cases in other EU countries from sporadic CJD have been taken down. however, from my files ;
IF we look at sporadic incidence of CJD in UK from 1993 to 2003, the incidence rose from 37 in 1993 to 77 in 2003. THIS seems to show an increase to me? I do not understand the statement ;
However, in the period following the first published description of vCJD in 1996, there was no increasing trend in the reported annual number of U.K. sporadic CJD deaths (52).
IF we go further and look at some of the other documented BSE countries, you will the increase of sporadic CJD there as well ;
Canada from 2 to 25
France from 35 to 108
Germany 21+ to 96
Italy 27 to 76

5 Includes 18 cases in which the diagnosis is pending, and 18 inconclusive cases;
6 Includes 23 (22 from 2010) cases with type determination pending in which the diagnosis of vCJD has been excluded.
Please notice where sporadic CJD cases in 1996 went from 28 cases, to 215 cases in 2009, the highest recorded year to date. sporadic CJD is on a steady rise, and has been since 1996.
I also urge you to again notice these disturbing factors in lines 5 and 6 ;
5 Includes 18 cases in which the diagnosis is pending, and 18 inconclusive cases;
6 Includes 23 (22 from 2010) cases with type determination pending in which the diagnosis of vCJD has been excluded.

Proposal ID: 29403
Alzheimer’s disease and Transmissible Spongiform Encephalopathy prion disease, Iatrogenic, what if ?
Background
Alzheimer’s disease and Transmissible Spongiform Encephalopathy disease have both been around a long time, and was discovered in or around the same time frame, early 1900’s. Both disease, and it’s variants, in many cases are merely names of the people that first discovered them. Both diseases are incurable and debilitating brain disease, that are in the end, 100% fatal, with the incubation/clinical period of the Alzheimer’s disease being longer than the TSE prion disease. Symptoms are very similar, and pathology is very similar. I propose that Alzheimer’s is a TSE disease of low dose, slow, and long incubation disease, and that Alzheimer’s is Transmissible, and is a threat to the public via the many Iatrogenic routes and sources. It was said long ago that the only thing that disputes this, is Alzheimer’s disease transmissibility, or the lack of. today, there is enough documented science (some confidential), that shows that indeed Alzheimer’s is transmissible. The risk factor for friendly fire, and or the pass-it-forward mode i.e. Iatrogenic transmission is a real threat, and one that needs to be addressed immediately.
Methods
Through years of research, as a layperson, of peer review journals, transmission studies, and observations of loved ones and friends that have died from both Alzheimer’s and the TSE prion disease i.e. Heidenhain Variant Creutzfelt Jakob Disease CJD.
Results
The likelihood of many victims of Alzheimer’s disease from the many different Iatrogenic routes and modes of transmission as with the TSE prion disease. TSE prion disease survives ashing to 600 degrees celsius, that’s around 1112 degrees farenheit. you cannot cook the TSE prion disease out of meat. you can take the ash and mix it with saline and inject that ash into a mouse, and the mouse will go down with TSE. Prion Infected Meat-and-Bone Meal Is Still Infectious after Biodiesel Production as well. the TSE prion agent also survives Simulated Wastewater Treatment Processes. IN fact, you should also know that the TSE Prion agent will survive in the environment for years, if not decades. you can bury it and it will not go away. TSE prion agent is capable of infected your water table i.e. Detection of protease-resistant cervid prion protein in water from a CWD-endemic area. it’s not your ordinary pathogen you can just cook it out and be done with. that’s what’s so worrisome about Iatrogenic mode of transmission, a simple autoclave will not kill this TSE prion agent.
Conclusions
There should be a Global Congressional Science round table event (one of scientist and doctors et al only, NO CORPORATE, POLITICIANS ALLOWED) set up immediately to address these concerns from the many potential routes and sources of the TSE prion disease, including Alzheimer’s disease, and a emergency global doctrine put into effect to help combat the spread of Alzheimer’s disease via the medical, surgical, dental, tissue, and blood arena’s. All human and animal TSE prion disease, including Alzheimer’s should be made reportable in every state, and Internationally, WITH NO age restrictions. Until a proven method of decontamination and autoclaving is proven, and put forth in use universally, in all hospitals and medical, surgical arena’s, or the TSE prion agent will continue to spread. IF we wait until science and corporate politicians wait until politics let science _prove_ this once and for all, and set forth regulations there from, we will all be exposed to the TSE Prion agents, if that has not happened already. what’s the use of science progressing human life to the century mark, if your brain does not work?

Abstract
Ample justification exists on clinical, pathologic, and biologic grounds for considering a similar pathogenesis for AD and the spongiform virus encephalopathies. However, the crux of the comparison rests squarely on results of attempts to transmit AD to experimental animals, and these results have not as yet validated a common etiology. Investigations of the biologic similarities between AD and the spongiform virus encephalopathies proceed in several laboratories, and our own observation of inoculated animals will be continued in the hope that incubation periods for AD may be even longer than those of CJD.

De novo induction of amyloid-ß deposition in vivo
Our results suggest that some of the typical brain abnormalities associated with AD can be induced by a prion-like mechanism of disease transmission through propagation of protein misfolding. These findings may have broad implications for understanding the molecular mechanisms responsible for the initiation of AD, and may contribute to the development of new strategies for disease prevention and intervention.
