OBJECTIVES:Visceral leishmaniasis (VL) is an extremely rare example of opportunistic infection in patients treated with TNF-alpha antagonists and only a few cases have been described. In this paper risk factors, clinical features, diagnostic work-up and outcome of patients developing VL under biologic therapy are described.METHODS:Case report and review of the published cases of VL in patients under biologic treatment.RESULTS:We retrieved six patients, including ours, all of whom presented anarchic fever and pancytopenia. In 5 cases, splenomegaly was detected. The same number of patients came from endemic areas for VL. In the majority of the cases a bone marrow examination was not diagnostic, requiring the performance of a second one and/or the execution of other diagnostic tests.

Abstract

OBJECTIVES:Visceral leishmaniasis (VL) is an extremely rare example of opportunistic infection in patients treated with TNF-alpha antagonists and only a few cases have been described. In this paper risk factors, clinical features, diagnostic work-up and outcome of patients developing VL under biologic therapy are described.METHODS:Case report and review of the published cases of VL in patients under biologic treatment.RESULTS:We retrieved six patients, including ours, all of whom presented anarchic fever and pancytopenia. In 5 cases, splenomegaly was detected. The same number of patients came from endemic areas for VL. In the majority of the cases a bone marrow examination was not diagnostic, requiring the performance of a second one and/or the execution of other diagnostic tests. One fatal outcome was observed.CONCLUSION:Even if VL represents a sporadic complication of biologic treatments, its presence should always be suspected in patients developing a triad of signs and symptoms constituted by fluctuant fever, pancytopenia and splenomegaly, especially if coming from endemic areas. In these cases an extensive diagnostic work-up must be warranted. Atypical and confusing features may resemble autoimmune diseases at presentation and during the course of the illness.
