Abstract

Background: Treatment of hookworm-related cutaneous larva migrans (HrCLM) with a single dose of oral ivermectin has not been adequately evaluated to date. Response rates reported in three large studies varied from 77% to more than 95%.

Objectives: We evaluated the efficacy of ivermectin in the treatment of HrCLM.

Methods: We retrospectively studied all returning travellers with HrCLM who consulted in our institution. Patients were then treated with a single, 200 μg/kg dose of ivermectin, orally.

Results: Sixty-two travellers (35 female, 27 male, mean age 35.6 years) with HrCLM and creeping dermatitis were included. Six patients (10%) also had associated hookworm folliculitis. Fifty-nine patients (95%) completely responded with one ivermectin dose. The response rate was 98% in the 56 patients presenting with only creeping dermatitis and 66% in the six patients presenting with additional hookworm folliculitis (P = 0.02).

Conclusion: The efficacy of a single dose of oral ivermectin is higher in patients with only creeping dermatitis than in those with associated hookworm folliculitis.
