Abstract:
Antibody to the hepatitis delta virus (anti-δ) was detected in 112 out of 2487 (5%) individuals fortuitously found to have the hepatitis B surface antigen (HBsAg) in the blood. Liver function was impaired in 38% (43 of 112) of the anti-δ-positive carriers but in only 9% (215 of 2375) of the anti-δ-negative subjects (p<0·001). Liver biopsy specimens were obtained from 31 antibody-positive and 97 antibody-negative subjects with impaired liver function. Important histological changes were observed in 61% of the 31 antibody-positive carriers (7 chronic active hepatitis, 4 active cirrhosis, 8 inactive cirrhosis) but in only 19% of the 97 antibody-negative carriers (p<0·001). The presence of anti-δ in serum identifies a subpopulation of apparently healthy HBsAg carriers whose risk of underlying liver disease is four times higher than that in the ordinary carrier. The identification of anti-δ in a symptom-free HBsAg carrier with abnormal liver function is thus an indication for a diagnostic liver biopsy.
