Objectives: To evaluate the evidence for use of different formulations of amphotericin B (AmB), minimum effective dose for each formulation and its comparative efficacy against other drugs in achieving definitive cure of visceral leishmaniasis.
Methods: This systematic review and meta-analysis included following data sources: PubMed, Embase, Scopus, Web of Science and CINAHL. Controlled prospective clinical trials (randomized or non-randomized, including dose-ranging studies) conducted between 1996 and 2017 with at least one treatment group receiving AmB were included (published data only). The primary outcome was definitive cure at 6 months. Adverse events and mortality were assessed as secondary outcomes. The PROSPERO registration number for this review is CRD42017067488.
Results: Thirty-one studies (26 from India) that enrolled 6903 patients into 84 study groups met the selection criteria. In India, liposomal AmB was not inferior to AmB deoxycholate (relative risk 1.00, 95% confidence interval (CI) 0.96-1.03, two randomized controlled trials (RCTs), 514 participants, high-quality evidence), and a single dose of the earlier formulation as low as 3.75 mg/kg achieved a cure rate of over 89% (95% CI 70.6-97.2). AmB deoxycholate was as effective as miltefosine (relative risk 0.99, 95% CI 0.95-1.03, two trials, 523 participants, high-quality evidence) and may be better than paromomycin (relative risk 1.04, 95% CI 1.02-1.07, one trial, 667 participants, low-quality evidence) in achieving definitive cure.
Conclusions: AmB is an efficacious drug in the Indian subcontinent. Further evidence is needed from prospective clinical trials in other endemic geographical regions.
