    Abstract:
    Management of chronic/recurrent erythema nodosum leprosum (ENL) is challenging. The majority of these patients become steroid-dependent and suffer from the adverse effects of long-term corticosteroid use. Minocycline has shown promising results in a small series of chronic/recurrent ENL patients. The aim of this study was to compare the efficacy and safety of minocycline and clofazimine in patients with chronic/recurrent ENL. In this prospective randomized clinical trial, 60 participants with chronic/recurrent ENL were randomized (1:1) to receive either minocycline 100 mg once daily or clofazimine 100 mg thrice daily for 12 weeks along with prednisolone according to WHO protocol and followed up for 6 months. The outcome measures were mean time for initial control of ENL, proportion of patients having a recurrence of ENL, mean time for recurrence after initial control, additional prednisolone requirement, and frequency of adverse events. Initial control of ENL was achieved earlier in the minocycline group as compared to the clofazimine group (2.97 ± 1.9 weeks vs. 4 ± 1.96 weeks, respectively; p-0.048). The number of participants having ENL flares/recurrences during the study period was comparable in both groups (71.4% in clofazimine vs. 55.2% in minocycline group; p-0.2). The participants in the minocycline group remained in remission for a longer duration after initial control of ENL as compared to the clofazimine group (p-0.001). Mean additional prednisolone dose required for control of ENL flares/recurrences was also comparable in both groups (p-0.09). The minocycline group had fewer side effects than the clofazimine group (p-0.047). Minocycline led to a rapid and sustained improvement of ENL episodes with fewer adverse events showing a superior efficacy to clofazimine.
