[Visceral leishmaniasis in an HIV positive patient]

visceral leishmaniasis is the most serious clinical picture of leishmaniasis or kala azar. In Mexico it is a rare disease, which is a reason why it is diagnosed late concluding with patient's death most of the time. We present a clinical case of an HIV-positive male patient who developed visceral leishmaniasis, with the objective of showing the pathophysiological characteristics as well as the diagnostic approach and treatment.

a 45-year-old male, a water utility company worker, presented to the hospital as having chronic bloody diarrhea, abdominal distension, cramping pain, weight loss and fever. On physical examination, he was febrile, with pain localized to the right lower quadrant and hepatosplenomegaly. The ELISA test for HIV was positive and the ultrasound showed a cecal tumor. A tumor biopsy was performed and the pathology report described leishmaniasis.

in patients with leishmaniasis and HIV the response to treatment is poor and the mortality rate is high due to lower immune response from the host. Current studies suggest treating these patients with HIV and leishmaniasis with pertinent drugs in combination with miltefosine and liposomal amphotericin B.
