[Successful treatment of pre-engraftment disseminated fusariosis with high-dose liposomal amphotericin B in a cord blood transplant recipient].

Abstract

A 47-year-old man with acute myeloid leukemia and myelodysplastic-related changes relapsed after an allogenic bone marrow transplant and received a cord blood transplant as salvage therapy. The patient developed febrile neutropenia that was resistant to broad-spectrum antibiotics and multiple, painful, nodular skin lesions on his trunk and extremities before engraftment. A skin biopsy and blood culture found mold, and the subsequent microscopic examination, mass spectrometry, and DNA sequencing of the fungal colonies identified Fusarium solani. The patient's fever and skin lesions began to improve with the administration of liposomal amphotericin B at 5 mg/kg/day. Neutrophilic engraftment occurred on day 19. Stage 3 acute skin graft-versus-host disease was cured by the application of topical steroid. Unexpectedly, a change from liposomal amphotericin B to voriconazole on day 38 exacerbated the Fusarium infection. The Fusarium infection was finally cured by the administration of liposomal amphotericin B for a total of 19 weeks. Neutrophilic engraftment, an immediate definitive diagnosis, the sufficient and long-term administration of appropriate antifungal medication, and avoidance of the systemic administration of steroids might have contributed to the successful outcome of this patient.
