Pulsed corticosteroid therapy in patients with chronic recurrent ENL: a pilot study

A pilot study has been undertaken to compare the efficacy of small dose pulsed betamethasone therapy with need based oral steroids in chronic recurrent erythema nodosum leprosum (ENL) patients. Though this mode of therapy was well tolerated, no advantage with intermettnt steroid administration was observed. This coul have been on account of small dose of steroid given monthly. Treatment of chronic recurrent erythema nodosum leprosum (ENL) patients continues to be unsatisfactory, particularly, because of non-availability of thalidomide. Though corticosteroids are effective in suppressing all the manifestations and even restoring partially or fully the functional impairment, their side effects and dependence are equally troublesome. Based on (a) the reported efficacy and safety of intermittent use of corticosteroids in several immune complex mediated disorders (Cathcart et al 1976, Kimberly et al 1979), Lieblin et al 1981 and Pasricah & Gupta 1984) and (b) ENL (type II) reactions having similar pathology, a pilot study has been undertaken to see the efficacy and the tolerance of pulsed steroids in chronic ENL patients
