Effect of HIV infection on the clinical spectrum of leprosy in Maiduguri

Abstract

The clinical features associated with different classes of leprosy patients co-infected with HIV in Maiduguri was studied and the classification of leprosy was done clinically and bacteriologically using Ridley-Jopling classification and bacteriological index respectively. The cases were classified as paucibacillary (Tuberculoid--TT and Borderline Tuberculoid--BTT) and multibacillary (Borderline Borderline--BB, Borderline Lepromatous BL and Lepromatous Leprosy--LL) leprosy. Eleven (10.5%) of 105 leprosy cases were HIV-seropositive comprising of 7 males and 4 females. Age range was 15 and 62 years. Among the HIV seropositive patients, those with paucibacillary (PB) leprosy were 6 (TT-1, BT-5) while multibacillary (MB) leprosy 5 (BB-1, BL-2, LL-2). The predominant clinical features were clawing of fingers (64%), ulcerations (64%), hand muscle atrophy (55%) and clawing of toes (45%). Some clinical features of paucibacillary leprosy such as sensory and hair losses (as is also seen in HIV negative patients) occurred in increased frequency in HIV positive patients belonging to the multibacillary class. The HIV infected leprosy patients are more likely to manifest advanced stages of the disease than the HIV seronegative patients.
