Studies on Clinical Aspects, Pathological Changes, Immunohistochemistry, 14-3-3 protein, PrP Gene, and Animal Transmission of Creutzldt-Jakob Disease in China
Objectives To investigate the clinical manifestations, pathological changes, expression of PrP gene, 14-3-3 protein in cerebrospinal fluid (CSF) and experimental animal transmission of Creuizfeldt-Jakob disease (CJD) in China. Methods Clinical aspects of 24 patients with CJD which was confirmed neuropathological were evaluated. Brain sections of 10 cases of them were given immunostaining with antiserum to a synthetic polypeptide of prioni protein (PrP). PrP gene was analyzed in 10 cases, and 14-3-3 protein in CSF was detected in 5 cases. Experimental mouse transmission was carried out using brain suspension from 7 patients with CJD. Results 1) Nineteen cases with sporadic CJD, 3 cases with iatrogenic CJD, 1 case with inherited CJD and 1 case with coexistence of Alzheimer disease(AD) and CJD were found. 2) The percentage of acute and subacute onset was high up to 96%. The illness duration was shorter in a subacute onset and the brain atrophy was not obvious.3) The synaptic type of PrP deposition was shown in paraffin sections in all -cases by immunostaining.4) 14-3-3 protein was detected in 5 eases in cerebrospinal fluid with CJD 5) Spongiform degeneration and PrP deposition could be shown in the brain sections of experimental mouse transmission. Conclusion There are special characteristics in clinical aspects of CJD in China. The detection of 14-3-3 protein can provide objective evidence for early diagnosis of CJD in order to prevent its transmission
