Artemisinin and its derivatives have been found effective in vivo against Plasmodium and in vitro against Toxoplasma gondii and Pneumocystis carinii. We tested the activity of artemether for prophylaxis and treatment in the rat model of concurrent T. gondii and P. carinii infection. Artemether at doses of 18 and 100 mg/kg administered (s.c.) in prophylaxis did not prevent toxoplasmosis or pneumocystosis, while trimethoprim-sulfamethoxazole (reference treatment) was effective for prevention of both infections. Similar results were obtained in curative studies. These results do not support the use of artemether for prevention or treatment of toxoplasmosis or pneumocystosis.
Résumé
L'artemisinine et ses dérivés ont une activité anti-Plasmodium in vivo et une activité anti-Toxoplasma gondii et anti-Pneumocystis carinii in vitro. L'artémether a été évalué en prophylaxie et en traitement de la toxoplasmose et de la pneumocystose chez le rat co-infecté. Contrairement au triméthoprime-sulfaméthoxazole (traitement de référence), l'artémether, aux doses de 18 ou 100 mg/kg (administré par voie sous-cutanée) ne permet ni la prévention ni le traitement de la pneumocystose et de la toxoplasmose.
