Antibodies to hepatitis C virus and chronic hypertransaminasemia in southern Italy.
In an ecographic survey for gallstones, executed on a systematic sample from the municipal electoral roll of a town in Southern Italy, 164 subjects were found with ALT more than twice the upper normal limit (unl). Five years later 138 of these were re-examined; 76 still had ALT greater than 2 unl (group A), 41 still abnormal (group B) and 21 normal (group C). Anti-HCV antibodies were found in 52 subjects of group A (68%). 18 of group B (44%) and 2 of group C (9.5%). The odds ratio of ALT greater than 2 unl (A vs C) in anti-HCV+ was 20.6 and of a still elevated ALT (A + B vs C) was 14.1. Logistic regression was used to eliminate the effect of possible confounding factors (sex, age, alcohol, drugs, HBV markers) on the relationship chronic ALT increase and anti-HCV positivity but the odds ratio was still 18.9 (A vs C) and 11 (A + B vs C). These findings suggest that anti-HCV antibodies are strongly associated with chronic hypertransaminasemia at the population level in Southern Italy.
