[Torsades de pointes during treatment of leishmaniasis with meglumine antimoniate].

Antimonial agents are the main drug to treat all forms of leishmaniasis. Meglumine antimoniate is the drug available in Spain and it is usually well tolerated. Nevertheless, this drug frequently alters ventricular repolarization, but few cases of sudden death, presumably related to ventricular arrhythmias, have been reported. We present a case of torsade de pointes during treatment with meglumine antimoniate coexisting with a severe hypokalemia probably due to an acute transitory tubulopathy.
