Mortality trend from sporadic Creutzfeldt-Jakob disease (CJD) in Italy, 1993-2000.
The objective was to identify any possible cases of variant Creutzfeldt-Jakob disease (CJD) in Italy, and to estimate the trends in mortality from sporadic CJD for 1993-2000. CJD cases were ascertained through direct notification to the Registry; 382 definite or probable sporadic CJD patients, but no cases of variant CJD were identified. The average yearly mortality rate was 1.04 cases per million inhabitants, with an increase in deaths in the 60-69 and > or =70 year age groups. Survival was shorter in male respect to female and in patients with an age at onset > or =65 years. CJD cases were uneven distributed among different regions in the period 1993-1995, but not herein after. The rise in mortality from sporadic CJD in Italy likely reflects increased awareness and better diagnosis during the years. However, continuous notification and postmortem examination of all suspected cases are recommended for optimal surveillance.
