Abstract We investigated the epidemiological and clinical characteristics, to provide evidence for the control and prevention of Creutzfeldt-Jakob disease (CJD) in Shaanxi Province, China. Clinical and epidemiological datas on 49 suspicious CJD patients from 7 hospitals in Shaanxi Province from 2011 to 2015 was collected. Blood and cerebral spinal fluid (CSF) specimens from the cases were gathered. For CSF sample, 14-3-3 protein were tested by Western blot. For blood sample, PCR and sequencing were used, and then the mutation of PRNP gene and the polymorphism of 129 and 219 amino acids were analyzed. It showed that a total number of 16 probable and 4 possible sporadic CJD patients, and 1 familial CJD case were identified. Among these cases, neither geographic nor occupational-related ones were found. The median age of onset for the probable sporadic CJD cases was 62 years old, and the gender ratio of male to female was 1.29 to 1. The most initial symptom was rapid progressive dementia, which accounted for 47.62% of the CJD patients. This report indicates that the main type of CJD in Shaanxi Province is sporadic CJD with its distinctive characteristics including geography distribution, occupation, gender ratio and age of onset.

Key words： Creutzfeldt-Jakob disease surveillance 14-3-3 protein prion PRNP gene
