Risk Factors for Visceral Leishmaniasis Relapse in Immunocompetent Patients following Treatment with 20 mg/kg Liposomal Amphotericin B (Ambisome) in Bihar, India

Abstract

This is the largest cohort of VL patients treated with Ambisome worldwide. The risk factors for relapse included male sex, age <5 and ≥45 years, a smaller decrease in splenomegaly at discharge, and a shorter duration of symptoms prior to seeking treatment. The majority of relapses in this cohort occurred 6-12 months following treatment, suggesting that a 1-year follow-up is appropriate in future studies.
