Antihelminthic therapy and antimony in cutaneous leishmaniasis: a randomized, double-blind, placebo-controlled trial in patients co-infected with helminths and Leishmania braziliensis.

Helminth infections influence the clinical response to certain diseases and are associated with delayed healing time of patients with cutaneous leishmaniasis (CL) caused by Leishmania braziliensis. We conducted a randomized, double-blind, placebo-controlled clinical trial to examine the role of early versus deferred treatment of intestinal helminth infection on the clinical course of patients with CL treated with pentavalent antimony. (Clinicaltrials.gov number NCT00469495). A total of 90 patients were enrolled, 51.1% (N = 23) of control patients had persistent lesions at Day 90, compared with 62.2% (N = 28) in the treatment group (difference 11.1%, 95% confidence interval = -9.1-30.0%). There was no statistically significant difference in overall time to cure between groups, although there was a tendency for shorter cure times in the control group. This study shows that early introduction of antihelminthic therapy does not improve clinical outcome in patients co-infected with helminths and L. braziliensis.
