title: Litomosoides carinii in rodents: immunomodulation in potentiating action of diethylcarbamazine.
abstract: The antifilarial activity of combination of diethylcarbamazine (DEC) and an immunomodulator, N-Palmitoylmuramyl-L-alanyl-D-isoglutamine (NP-MDP) was evaluated against Litomosoides carinii in cotton rat (Sigmodon hispidus) and Mastomys natalensis. DEC was used at 6 mg/kg in cotton rat whereas it was 75 mg/kg x 5 days in mastomys. The immunomodulator was administered at 62.5 to 500 micrograms/animal x 2 days. Combination therapy with optimum dose of immunomodulator resulted in prolonged and significant suppression of microfilaraemia in comparison to infected animals treated only with DEC. The effective doses of immunomodulator alone or in combination with DEC also caused enhanced antibody titre in treated animals. Though combination therapy resulted in prolonged suppression of microfilaraemia, the effect disappeared slowly and caused no damage to adult worms.
