Sumario: | Coccidioides is an endemic fungus of the Southwest United States that causes the disease coccidioidomycosis. Immunocompromised persons are at increased risk for severe infection and dissemination. One such population is allogeneic bone marrow transplant (allo-HCT) recipients, but accounts of coccidioidal infection in these patients have rarely been documented. We present two cases of Coccidioides in allo-HCT recipients with good outcomes: one patient who developed pulmonary coccidioidomycosis in the late post-engraftment phase and another with known controlled disseminated infection at the time of transplant. A review of the literature identified 19 allo-HCT recipients with coccidioidomycosis. Due to the limited published literature, no guidelines have yet been established regarding optimal prophylaxis and treatment of Coccidioides infection in allo-HCT recipients. Candidates for transplantation should undergo a rigorous pre-transplant assessment to identify evidence of prior or active coccidioidomycosis. In our experience, patients who visit or live in Coccidioides-endemic areas should receive primary prophylaxis for at least the first 100 days post-transplant, and duration should be extended as long as the patient remains on immunosuppression. Those with prior infection should receive secondary prophylaxis while immunosuppressed. Patients with active infection should have treatment and stabilization of infection and continue anti-fungal treatment through immunosuppression. |
