COCCIDIOIDOMYCOSIS—Treatment with Isonicotinic Acid Hydrazide

摘要

Since coccidioidal granulomas are histologically indistinguishable from tuberculous granulomas, a long course of isonicotinic acid hydrazide therapy was tried experimentally in three cases of coccidioidomycosis, with good results. In two cases the disease was far advanced and prognosis poor before INH therapy was begun. In one case the disease was mild and symptoms abated after a short course of small doses of INH. It recurred when INH therapy was discontinued, and again resolved when larger doses of INH were given over a longer period.INH seemed to have an effect on appetite also, although the patients were taking B-complex vitamins both before and during INH treatment. The three patients ill with coccidioidomycosis averaged a weight gain of four and a half pounds a month during the period of INH therapy. Six well persons who were underweight and lacked appetite were given INH without other drugs, and they then had an increase in appetite and in weight.
