Abstract

Cutaneous leishmaniasis (CL) is a major health problem in endemic areas of Iran. The pentavalent antimony (SbV) based drug Glucantime is the first line of treatment for CL in Iran, but recently SbV-resistant Leishmania tropica isolates derived from unresponsive patients were reported. We show in this study that these resistant parasites are cross-resistant to the other SbV-containing drug Pentostam and at least for one isolate also to amphotericin B. However, these resistant isolates were shown to be sensitive to miltefosine and paromomycin. The latter two drugs could thus be useful alternatives for the treatment of leishmaniasis in Iran even for SbV-resistant isolates.
