Efficacy and safety of triple therapy versus dual therapy for lymphatic filariasis: A systematic review and meta-analysis.

Abstract

OBJECTIVE:

Lymphatic filariasis is a serious public health issue. Recent studies showed that a single dosage of triple therapy (Ivermectin, Diethylcarbamazepine, and Albendazole) is more effective than dual therapy (Ivermectin plus Albendazole or Diethylcarbamazepine plus Albendazole) for clearing microfilaria from the blood. We aimed to evaluate the efficacy and safety of triple therapy versus dual therapy in patients infected with microfilaria and communities endemic to lymphatic filariasis.

METHODS:

For this systematic review and meta-analysis, we searched MEDLINE, EMBASE, SCOPUS, Cochrane Central Register of Controlled Trials, and Web of Science until 24th June 2021. We included randomized control trials that compared triple with dual therapy given to patients with lymphatic filariasis or endemic communities. This study was registered with PROSPERO (CRD42021266724).

RESULTS:

We included eight articles after the screening process. Triple therapy caused more clearance of microfilaria in the blood (RR: 1.52; 95% CI: 1.15, 2.02; p = 0.003), while dual therapy caused more clearance of the circulating filariae antigen in the blood (RR: 0.76; 95% CI: 0.65, 0.88; p = 0.0003), both 12 months after drug administration. The triple therapy had a similar adverse effect compared with the dual therapy group.

CONCLUSION:

Based on the greater efficacy in the clearance of microfilaria and the safety of triple therapy, it constitutes a better strategy for the eradication programs of lymphatic filariasis in endemic regions. However, further studies are needed to confirm our results.
