Disseminated Fusarium infections in patients following bone marrow transplantation.
Intensive immunosuppressive therapy and broad spectrum antibiotics predispose cancer patients to opportunistic fungal infections. Fusarium has rarely been reported as a pathogen in immunocompromised patients, but is almost uniformly fatal. Only six cases of disseminated Fusarium infection have been described in patients following bone marrow transplantation (BMT). We report here two additional cases. Fusarium infection initially presented with pyomyositis in one patient and with embolic skin lesions in another following T cell-depleted BMT. Both patients died with active Fusarium infection despite an extensive course of amphotericin B, rifampicin and granulocyte transfusions. From this experience and from a review of the literature, Fusarium infections appear to be increasing in prevalence as significant pathogens in immunocompromised hosts and are resistant to many conventional forms of therapy.
