Three sporadic cases of Creutzfeldt-Jakob disease in China and their clinical analysis.

Abstract:

:The present study described the characteristics of three cases of Creutzfeldt-Jakob disease (CJD) in China and analyzed their clinical presentations. The clinical information of the three cases was collected and analyzed. Blood and cerebrospinal fluid (CSF) specimens of the patients were collected for detection of the prion protein (PRNP) gene and 14-3-3 protein levels. Dynamic changes of electroencephalograms (EEGs) and brain magnetic resonance images (MRIs) were also observed. All the three cases were sporadic CJD cases. They presented with symptoms including hyposthenia, progressive memory loss, truncal and limb ataxia, dysarthria, lowered vision acuity, bucking, language disorders, myoclonia and akinetic mutism state. One of the three cases was associated with a prolonged duration of >6 years. The EEG of two cases showed slow biphasic waves. The diffusion-weighted MRI sequence revealed abnormal hyperintensity and bilateral ribboning in the cortex. Two patients tested positive for the 14-3-3 protein in the CSF. All patients were of methionine homozygosity at codon 129 in the gene encoding PRNP protein and one patient had a mutation. The CJD cases showed differences in terms of symptoms and disease duration. Subacute onset was common and with attentive nursing and supportive treatments, one of the patients had a prolonged survival time of >6 years.
