Visceral leishmaniasis after kidney transplantation: Report of a new case and a review of the literature

Visceral leishmaniasis (VL) is a parasitic disease, caused by protozoa of the genus Leishmania, transmitted by the phlebotomies sand fly. In the last 20 years, the increasing frequency of organ transplantations and the improvement of associated immunosuppressive treatments have led to the recognition of several cases of VL complicating organ transplantation. Actually, less than 100 cases of VL after kidney transplantation are reported in the literature. In this context, VL is fatal without antileishmanial treatment which constitutes a difficult challenge.We report a case of VL in Tunisian renal transplant recipient treated successfully by liposomal amphotericin B (Ambisome®, Gilead Sciences Inc). Also, we review the epidemiological, clinical, biological and therapeutic aspects of VL associated with renal transplantation reported in the literature.Our report identifies that VL should be suspected in renal transplant recipients presenting unexplained fever, splenomegaly and pancytopeny. It also suggests a serological testing for leishmaniasis in the pre-operative check-up of transplant patients and donors living or traveling in endemic areas of leishmaniasis. Moreover, recipients should be tested regularly for leishmaniasis after transplantation. Liposomal amphotericin B may be considered the treatment of choice of VL, since it has a lower incidence of side effects.
