dc.description.abstractIntroducción: La incidencia de fungemias tiene alta morbimortalidad especialmente en pacientes con neoplasias hematológicas. El objetivo del estudio es describir las características epidemiológicas, clínicas y microbiológicas en pacientes adultos con fungemias con neoplasias. Materiales y métodos: En esta cohorte retrospectiva las historias clinicas y los reportes microbiologicos de todos los pacientes con neoplasias hematológicas y fungemias entre el 2012 al 2019 fueron identificados en instituciones de Bogotá. Resultados: Se identificaron 105 fungemias, edad promedio 48 años (DE 19.03); la mayoría en contexto de leucemias agudas (45%) y linfomas (37%). En 42% la enfermedad hematológica estaba en recaída/refractaria, 82% ECOG >3 y 35% recibían profilaxis antifúngica; 57% presentaron RAN <500 células/mm3, con una duración promedio de 21,78 días. Como factores de riesgo identificados 40% presentó infección relacionada con CVC, 17% mucositis y 13% uso de corticoides; 98% de los aislamientos correspondieron a levaduras y 2% a hongos miceliales; la mortalidad global fue del 50%. El total de los hongos miceliales identificados correspondieron al género Fusarium spp mientras el total de las levaduras 82% (86 pacientes) fueron por Candida spp y 18% por otras levaduras; 61% Candida no albicans de las cuales Candida tropicalis (28%) Candida parapsilosis 17% y Candida krusei 12% se identificaron. La probabilidad de supervivencia al día 30 para los pacientes con diagnóstico de leucemia fue del 59% (IC de 46-76) y en el grupo de linfoma/MM del 41% (IC 29-58), p=0.03. En el análisis univariado, la edad (HR 1,01 p=0.043), diagnóstico por grupo Linfoma/MM (HR 1,86 p=0,029), ingreso a UCI (HR 3,14 p=<0.01) y choque séptico (HR 1,38 p=<0.01) estuvieron estadísticamente asociados con incremento de la mortalidad. En el análisis multivariado el grupo diagnóstico (HR 1,72 p=0.04) y el ingreso a UCI (HR 3.08 p=<0.01) se relacionaron con mortalidad con significancia estadística. Conclusiones: las fungemias son un problema relevante en pacientes con neoplasias hematológicas con una mortalidad global significativa. El perfil epidemiológico ha cambiado con mayor frecuencia de aislamientos de C. tropicalis. Conocer los factores de riesgo de mortalidad es fundamental para un abordaje apropiado de estos pacientes.

dc.description.abstractIntroduction: The incidence of fungaemia has high morbimortality especially in patients with hematological malignancies. The goal of the study is to describe the epidemiological, clinical and microbiological characteristics in adult with fungemia and cancer Materials and methods: an observational retrospective cohort multicenter. We retrospectively reviewed charts of hospitalized patients with in which a documented fungaemia was diagnosed between 2012 and 2019 in hospitals in Bogota. Results: we recorded 105 fungal bloodstream infections. Average age 48 years (SD 19.03); most in the context of acute leukemias (45%) and lymphomas (37%). In 42% the hematologic disease was relapsed/refractory, 82% ECOG >3 and 35% were receiving antifungal prophylaxis; 57% presented RAN <500 cells/mm3, with an average duration of 21.78 days. The identified risk factors were, 40% had CVC-related infection, 17% had mucositis and 13% had corticosteroid use; 98% of the isolates corresponded to yeasts and 2% to moulds; overall mortality was 50%. The total of moulds identified corresponded to Fusarium spp while the total of yeasts 82% (86 patients) were Candida spp and 18% other yeasts; 61% non-albicans Candida of which Candida tropicalis (28%) Candida parapsilosis 17% and Candida krusei 12%. The probability of survival at day 30 for patients with a diagnosis of leukemia was 59% (CI 46-76) and in the lymphoma/MM group 41% (CI 29-58), p=0.03. In the univariate analysis, age (HR 1.01 p=0. 043), diagnosis by Lymphoma/MM group (HR 1.86 p=0.029), ICU admission (HR 3.14 p=<0.01) and septic shock (HR 1.38 p=<0.01) were statistically associated with increased mortality. In the multivariate analysis, the diagnostic group (HR 1.72 p=0.04) and admission to ICU (HR 3.08 p=<0.01) were statistically significantly associated with mortality. Conclusions: Fungaemia are a relevant problem in patients with hematological malignancies with significant overall mortality. The epidemiological profile has changed with a higher frequency of C. tropicalis isolates. Knowing the risk factors for mortality is essential for an appropriate approach to these patients.
