Immunological status of maculo-anaesthetic leprosy: T and B lymphocytes and serum immunoglobulins.

Peripheral blood T and B lymphocyte percentage and serum immunoglobulin levels were evaluated in 36 Maculo-anaesthetic (MA) leprosy patients using E and EAC rosette techniques and single radial immuno-diffusion respectively. 21 Tuberculoid, 13 Indeterminate, 16 Borderline, 13 Lepromatous and 20 healthy controls were also studied for comparison. The results showed that the peripheral blood T lymphocyte percentages and humoral immune responses of Maculoanaesthetic leprosy are not significantly different from either Tuberculoid or Indeterminate leprosy types or from control group.
