Abstract

Objectives: The Global Programme to Eliminate Lymphatic Filariasis recommends albendazole in combination with other antifilarial drugs. This systematic review examines albendazole in treatment and control of lymphatic filariasis. DATASOURCES: The Cochrane Controlled Trials Register, MEDLINE and EMBASE to April 2005; contacting experts, international organisations and drug manufacturers.

Methods: Randomised or quasi-randomised controlled trials included; two reviewers independently assessed eligibility, quality, and extracted data. We calculated the relative risk of microfilaraemia (mf) prevalence using fixed effect, or random effects model in case of heterogeneity.

Results: Six trials met inclusion criteria. Three trials compared albendazole with placebo: no effect was demonstrated on mf prevalence, but density was lower in one of the three studies at 6 months. Three trials added albendazole to ivermectin, with no demonstrable effect; prevalence tended to be lower at 4--6 months but not at 12 months (4--6 months; RR 0.49, 95% CI 0.18 to 1.39, n=255, 2 trials; 12 months: RR 1.00, 95% CI 0.88 to 1.13, n=348, 2 trials). Mf density was significantly lower in two of the three trials; one of two trials measuring density at 12 months showed a difference. Three trials added albendazole to diethylcarbamazine; two were small trials with no difference demonstrated; the third study tended to favour combination at 6 months (RR=0.62, 95% CI 0.32 to 1.21, n=491), with a significant difference for density.

Conclusions: The effect of albendazole against adult and larval filarial parasites, alone and in combination with other antifilarial drugs, deserves further rigorous research.
