Summary: Paromomycin is used to treat multiple clinical presentations of the neglected tropical disease leishmaniasis, including post-kala-azar dermal leishmaniasis, in which Leishmania parasites divide and reside in the skin. Little is known about the distribution of antileishmanial drugs in skin of patients after systemic treatment. Target-site PK data are urgently needed to further optimize and rationalize therapy. The authors present a target-site bioanalytical method to quantify paromomycin in skin tissue of patients with post-kala-azar dermal leishmaniasis from Sudan, using ultra-high performance liquid chromatography coupled to tandem mass spectrometry. This bioanalytical assay performed within approved European Medicines Agency acceptance criteria for accuracy and precision, and paromomycin was accurately quantified in skin of post-kala-azar dermal leishmaniasis patients originating from clinical trials in Sudan.
