Therapeutic trial of sodium antimony gluconate alone and in combination with ketoconazole in post-kala-azar dermal leishmaniasis.

BACKGROUND: Drugs used in PKDL include parenteral sodium antimony gluconate (SAG), amphotericin-B, pentamidine, and ketoconazole (KTZ). SAG is the most effective one. Given alone, SAG has to be given for a long duration, leading to poor patient compliance and treatment failure. This study was carried out to compare the effectiveness of SAG alone and a combination of SAG and KTZ for sixty days. METHODS: Ten patients of PKDL were included in the study. Five patients (Group A) were given SAG intravenously, in the dose of 20 mg/kg per day and five (Group B) were given SAG (intravenously 20 mg/kg per day) and KTZ (200 mg twice daily orally). Both treatment regimens were given for sixty days. RESULTS: In Group A, the nodules and/or plaques showed approximate 80-85% clinical improvement, and macules showed 25-30% improvement. In group B (SAG + KTZ), there was 90-95% clinical improvement in the nodules and/or plaques and 25-30% in macules. CONCLUSION: This study suggests the therapeutic superiority of the combination treatment regimen in a shorter duration but is not conclusive as the number of patients was low. Further trials are recommended.
