Hepatitis-B virus infection in patients with leprosy--a brief communication

The prevalence rate of hepatitis-B surface antigen (HBsAg) were determined in 413 patients of different types of leprosy and 133 healthy controls from the same population, in a study undertaken over a period of more than 3 years. The average frequency of australia antigen (HBsAg) was 7.7% in leprosy cases as compared to 6.0% in their healthy counterparts. Across the spectrum 7.2% of lepromatous patients (LL); 8.5% of borderline lepromatous (BL); 9.1% of borderline borderline (BB); 8.6% of borderline tuberculoid (BT) and 8.8% of tuberculoid (TT) cases were positive for HBsAg. Though the prevalence of australia antigen was slightly higher in borderline tuberculoid, borderline borderline and tuberculoid cases, it is not statistically significant. No association between carriership of HBsAg and lepromatous leprosy could be found in the present study.
