Serological responses in primary neuritic leprosy.
The serological responses to 2 Mycobacterium leprae specific epitopes and one common mycobacterial antigen were examined in 46 untreated patients with primary neuritic (PN) leprosy. M. leprae specific antibodies to the terminal disaccharide of phenolic glycolipid and/or the ML-04 defined epitope on the 35 kDa protein were detected in 41% of PN patients and 47% responded to one of the 3 antigens. This serological response mirrored that observed in paucibacillary leprosy patients. There was a significant increase in the level of antibody response when more nerve trunks were involved. Changes in antibody levels in seropositive PN patients may prove useful in monitoring the response to chemotherapy.
