Antifilarial compounds in the treatment and control of lymphatic filariasis.
Diethylcarbamazine citrate (DEC) has been used for treatment and control of lymphatic filariasis since the 1950s. Although this remarkable drug is still useful and modified strategies in its usage have been developed, a number of newer antifilarial compounds are now available. Numerous field trials evaluating their efficacy in the control of lymphatic filariasis have been conducted. In particular, ivermectin (IVM), albendazole (ALB), and DEC have been tested singly and in combinations and the results of such field studies should be evaluated. While most of the studies were based on efficacy in the clearance of microfilaraemia, a few clinical trials evaluated the adulticidal activity of these compounds. Some antibiotics are effective in killing Wolbachia bacteria symbionts of filarial worms, but their role in the chemotherapy of lymphatic filariasis is still undefined. This review of randomised controlled field studies and randomised controlled clinical trials with these compounds will summarise the findings and give recommendations on their appropriate use for the control and treatment of lymphatic filariasis.
