Abstract

An extraordinary incidence of genetic Creutzfeldt-Jakob disease (gCJD) appearing in clusters in the Slovak Republic was described in the 1990's. The aim of the study was to analyse data of CJD cases obtained from surveillance in Eastern Slovakia (ES) (2004-2016), the region outside the described geographical clusters. The database set in the project was the source for epidemiological and clinical analysis of CJD cases. The incidence of CJD in ES (2004-2016) was 1.7/million person-years (95% CI 1-2.4); the incidence increase in the last five years (2012-2016) was comparable to the whole country. Twenty seven of 29 reported CJD cases were available for analysis (mean age 59 years, F/M 15/12). The proportion of gCJD (E200K mutation) cases remained dominant (78%), with 9 familiar cases originating in 4 families. Analysis of the clinical features revealed shorter duration of the symptomatic phase in sporadic CJD (sCJD) (3.4 months) versus gCJD (5.15 months). Cognitive/behavioural changes, insomnia, and sensory disturbance were more pronounced in the early symptoms of gCJD. Periodic EEG discharges were more frequent in sCJD (83%) than gCJD (56%), all 19 available MR findings were CJD specific and localisation of abnormalities varied ...Continue Reading
