Zusammenfassung

Die zunehmende Resistenz des Malariaerregers Plasmodium falciparum gegenüber den gängigen Medikamenten erfordert anhaltende Anstrengungen, neue Wirkstoffe zu finden. Deshalb untersuchten wir die in vitro Aktivität der antimykotischen Substanzen Clotrimazol, Fluconazol, Ketokonazol, Itraconazol, Flucytosin, Amphotericin B und Caspofungin gegen klinische Isolate von P. falciparum am Albert Schweizer-Krankenhaus in Lambaréné, Gabun. Für Fluconazol, Itraconazol und Caspofungin wurde hier erstmalig die in vitro Aktivität gegen Malariaparasiten festgestellt. Unsere Messergebnisse für Clotrimazol, Fluconazol, Itraconazol und Caspofungin ergaben mediane 50 % effektive Konzentrationen von 3,1 µg/mL, 1,9 µg/mL, 1,1 µg/mL and 1,1 µg/mL. Ketokonazol, Voriconazol, Flucytosin und Amphotericin B zeigten in unserer Studie nur wenig in vitro Aktivität gegen P. falciparum.

Summary

The increasing resistance of the malaria parasite Plasmodium falciparum to currently available drugs necessitates a continuous effort to develop new antimalarial agents. We therefore aimed to assess the in vitro activity of the antifungal drugs clotrimazole, fluconazole, ketoconazole, itraconazole, voriconazole, flucytosine, amphotericin B, and caspofungin against field isolates of P. falciparum from Lambaréné, Gabon. Using the histidin-rich protein 2 (HRP-2) assay we determined the drug susceptibility (EC50, EC90) of 16 field isolates obtained from outpatients attending the Albert Schweitzer Hospital in Lambaréné, Gabon. For fluconazole, itraconazole and caspofungin the in vitro growth inhibition of these drugs is reported for the first time. Our data indicate that clotrimazole, fluconazole, itraconazole and caspofungin show median EC50 values of 3.1µg/mL, 1.9µg/mL, 1.1µg/mL and 1.1µg/mL respectively. Ketoconazole, voriconazole, flucytosine and amphotercin B showed no relevant growth inhibition within the range of drug concentrations used in this study.
