Bacillaemia and Mycobacterium leprae cell wall antigen in paucibacillary leprosy

A study was undertaken to estimate bacillaemia and M. leprae antigen detection in 54 paucibacillary leprosy patients (TT, BT). Acid-fast bacilli were detected in the blood of 14.8% patients of borderline tuberculoid (BT) leprosy. M. leprae antigen was demonstrated in 48.2% patients of BT leprosy. Slit-skin smears were negative in all these patients. At the end of treatment (6 months of WHO-MDT) all the follow-up bloos samples were negative for both bacillaemia and M. leprae antigen in the serum
