Abstract
The purpose of this prospective study was to update epidemiological data on cutaneous larva migrans (CLM) and to assess the: therapeutic efficacy of i vermectin. We performed the study between June 1994 and December 1998 at ou r travel clinic. Ivermectin (a single dose of 200 g/kg) was offered to all the patients with CLM, and its efficacy and tolerability were assessed by a questionnaire. Sixty-fouls patients were enrolled. All were European and h ad stayed in tropical areas. After the patients had returned from their des tinations, 55% had lesions occur within a mean of 16 days (range, 1-120 day s; >1 month in 7 patients). The initial diagnosis was wrong in 55% of patie nts. The mean number of lesions was 3 (range, 1-15), and the main sites wer e the feet (48%) and buttocks (23%). The cure rate after a single dose of i vermectin was 77%. In 14 patients, 1 or 2 supplementary doses were necessar y, and the overall cure rate was 97%. The median time required for pruritus and lesions to disappear was 3 and 7 days, respectively. No systemic adver se effects were reported. Physicians' knowledge of CLM, which can have a lo ng incubation period, is poor. Single-dose ivermectin therapy appears to be effective and well tolerated, even if several treatments are sometimes nec essary.
