Abstract

To test the capacity of cimetidine to enhance cellular immunity in patients with lepromatous leprosy (LL), cimetidine was given for one month to 29 inactive LL patients and 3 active LL patients. Immune function was monitored with skin tests (lepromin, PPD, candida, and trichopytin), lymphocyte transformation tests (phytohemagglutinin, BCG, and Dharmendra lepromin), and quantitation of peripheral blood lymphocyte subpopulations. A small but significant 'booster' response to PPD was the only change observed in the study of patients with inactive disease, and leprosy-related reactions did not occur. In the few active LL patients studied, neither immune enhancement nor leprosy-related reactions were observed. The results of this investigation suggest that cimetidine can be used safely in patients with inactive lepromatous leprosy.
