CUTANEOUS LEISHMANIASIS IN BRITISH TROOPS FROM BELIZE

The medical records of 306 British soldiers in whom a clinical diagnosis of cutaneous leishmaniasis had been made following a tour of duty in Belize were analysed. Parasitological confirmation of the diagnosis was established in 1 8 7 cases; leishmania were cultured in 117 cases and Leishman-Donovan bodies were identified histologically in a further 70 cases. Leishmania braziliensis braziliensis was identified in 78 cases and Leishmania mexicana mexicana in a further 29 cases. Seventy-one per cent of patients had a single lesion which, in most cases, occurred on the exposed extremities. The mean diameter of the ulcers was 14 . 4 mm. Treatment with sodium stibogluconate was effective. Two regimens were used, consisting of either 600-800 mg daily given initially for 10 days, or 600 mg b.d. given initially for 14 days. Of those allocated to the lower dose regimen 48 . 5% were cured after the initial 10-day course, and ultimately the ulcers of 93% of patients healed following more prolonged treatment at this dose. Of those allocated to the higher dose regimen 6 3 . 9% were cured after the initial 14-day course and ultimately the ulcers of all patients healed after more prolonged treatment at this dose. A transient leucopenia and a rise in liver enzymes were noted during treatment, and these changes were dose-dependent. No cases of mucocutaneous leishmaniasis were encountered.
