  1. Decrease in HDV endemicity in Italy.

    Article - En anglais


    To evaluate a possible variation in hepatitis D virus endemicity in Italy, the data from a multicentre study concerning HBsAg chronic carriers first observed in 31 liver units during 1992 were compared with the corresponding figures from a similar study performed in 1987.


    In both studies the methodology for the recruitment of cases was the same.

    The overall anti-HD prevalence in 1992 was 14.4%, a significantly lower rate than that observed in 1987 (23.4%, p<0.01).

    The decrease significantly (p<0.01) affected both males and females ; it occurred in all geographical areas, although to a greater extent in northern regions.

    It was evident in subjects below 50 years of age, but not in subjects older than 50.

    A significant reduction in the anti-HD prevalence was seen in all forms of chronic hepatitis.


    These findings indicate a lower level of hepatitis D virus endemicity in Italy, probably as a consequence of the reported decreased pool of HBsAg chronic carriers, the reduced size of families, the improved socio-economic conditions and changes in intravenous drug abuser behaviour.

    All these factors may have affected the strength of hepatitis D virus infection which has greatly reduced the spread of the virus.
