Disseminated histoplasmosis in an adopted infant from El Salvador
- 25 Downloads
An HIV-negative 4-month-old infant recently adopted from El Salvador was admitted for high fever. Hepatosplenomegaly, anaemia, leucopenia, thrombocytopenia, increased transaminases, and diffuse interstitial pulmonary infiltration were present on admission. Granulomas were seen in bone marrow and liver biopsies without any organism. Disseminated histoplasmosis was diagnosed 2 weeks later when bone marrow and blood cultures taken on admission became positive forHistoplasma capsulatum and when histoplasmic antigen was detected in blood. The outcome was good after treatment with amphotericin B followed by itraconazole which was administered for a 6-month period without significant toxicity.
Disseminated histoplasmosis is very rarely seen in Europe but should be suspected in case of unexplained fever in immigrants from the endemic areas in the world, particularly when hepatosplenomegaly and pancytopenia are present. Bone marrow examination and culture, blood cultures, and antigen testing are the mainstays of the diagnosis.
