Tratamiento exitoso de una fusariosis diseminada en un paciente neutropénico febril con terapia antifúngica combinada de voriconazol más anfotericina B deoxicolato / Successful treatment of disseminated fusariosis in a febrile neutropenic patient with combined antifungal therapy of voriconazol plus amphotericin B deoxycholate

Resumen Presentamos el caso clínico de un paciente con una leucemia linfoblástica aguda (LLA) que desarrolló una fusariosis diseminada por Fusarium verticillioides durante un episodio prolongado de neutropenia febril post quimioterapia. Fue exitosamente tratado cuando se usó terapia combinada de voriconazol más anfotericina B deoxicolato.

We report a case of a patient with acute lymphoblastic leukemia (ALL), who developed a disseminated infection by Fusarium verticillioides during chemotherapy-induced neutropenia. He was successfully treated only after combination therapy with voriconazole plus amphotericin B deoxycolate was used, but not when these compounds were used in an isolated form.

Trasplante de médula ósea alogénico en un paciente con fusariosis diseminada y leucemia mieloide aguda / Allogeneic hematopoietic cell transplantation in a patient with disseminated fusariosis and acute myeloid leukemia

La infección diseminada por Fusarium se ha convertido en un problema creciente en las personas con neoplasias hematológicas malignas, principalmente en pacientes con leucemias agudas; se describen cada vez más casos en aquellos sometidos a un trasplante de médula ósea. No existe un tratamiento óptimo establecido para la fusariosis diseminada. La mortalidad global comunicada de esta infección oscila entre el 50 y el 80%. Se presenta a continuación el caso de un paciente de sexo masculino de 29 años, con diagnóstico de leucemia mieloide aguda, que presenta como complicación una fusariosis diseminada, y logra sobrellevar un trasplante alogénico de médula ósea en el Hospital Italiano de San Justo (Argentina) de forma exitosa.

Disseminated fusariosis has become an increasing problem in people with hematopoietic neoplasms, mainly in patients affected by acute leukemias, and even more in those who undergo hematopoietic cell transplantation. There is not an optimal treatment for disseminated fusariosis. The global mortality described in the literature is between 50% and 80%. We introduce a case of a 29 year old patient with diagnosis of acute myeloid leukemia complicated with disseminated fusariosis, who copes with an allogeneic hematopoietic cell transplantation with a successful outcome in the "Hospital Italiano de San Justo" (Argentina).

Disseminated fusariosis in a patient with acute lymphoblastic leukaemia: A case report and literature review

Fusarium spp are molds found in the soil and may be saprophytic or fa c u l t a t ive plant p a t h ogens. These are rare but important opportunistic pathogens in immunocompromised patients especially those with hematologic malignancies. Fusarium spp usually cause local infections such as onychomycosis and infections of surgical and burn wound. However more importantly, these pathogens can lead to severe disseminated infection with invo l vement of multiple organs including skin. This disseminated form of fusariosis occurs exclusively in patients with prolonged, severe neutropaenia especially in patients with acute leukaemia or those u n d e rgoing bone marrow transplantation. Prognosis of disseminated fusariosis is usually guarded if not recognized early. We report a rare case of disseminated fusariosis in a patient with acute lymphoblastic leukaemia.
