A case of visceral leishmaniasis in Austria

We report a patient aged 41 years with fever of unknown origin. Notable aspects of his travel history were a trip to the Philippines and a sailing trip around Sicily. The patient presented with fever up to 40 degrees C since 4 weeks, weakness, headache, hepatosplenomegaly and night sweat. No specific cause could be found. Based on clinical findings tuberculosis was suspected and empirical tuberculostatic treatment was started. However, during the following 6 weeks the patient's condition deteriorated. A bone marrow biopsy performed to exclude a haematological malignancy revealed Leishmania sp. in macrophages. This histological diagnosis was confirmed retrospectively by re-examination of a previously performed liver biopsy and by an increased anti-leishmania serum antibody titer of 1:1280. The patient was treated with sodium stibogluconate (pentostam, 850 mg) for 30 days and recovered slowly.
