A follow up study of borderline tuberculoid leprosy under sulphone monotherapy

A retrospective study is presented herewith of 94 cases classified as BT and treated with sulphone monotherapy. A system of scoring based on the number and extent of lesions, and nerve involvement was followed. It was observed that cases with a clinical score of 2 or having more than 15 lesions or patients with extensive lesions covering 3 or more of 7 sectors of the body had a bad prognosis in respect of time taken for subsidence, occurrence of deformities and most importantly occurrence of relapses. Hence it is suggested that such cases should be considered as Multibacillary and treated as such, despite bacteriological findings which may be either negative or a bacteriological positivity of less than 2 at any one site.
