RESUMO
BACKGROUND: The prevalence of multi-resistant microorganisms is a public health problem that continues to grow globally. There is a population that is mainly susceptible to being colonized and subsequently infected, and these are cancer patients. AIM: To identify the clinical and pathological characteristics of cancer patients and their relationship with infection with ESBL and CPE producing microorganisms. METHODS: A retrospective and analytical study was conducted between January 1, 2019 and June 30, 2020 in three hematooncological units. RESULTS: We included 3315 patients of which 217 (6.5%) were colonized by microorganisms producing ESBL and CPE. Of these, 106/217 (48.8%) had at least one episode of infection. The most frequently isolated microorganism was Klebsiella pneumoniae 29/106 (27.4%). Of those infected, 18/106 (17%) presented infection by the same colonizing microorganism. Mucositis (p = 0.002), age over 65 years (p = 0.041), hypoalbuminemia (p < 0.01), neutropenia (p < 0.01) and the presence of invasive devices (p < 0.01) demonstrated a relationship with development of infection. The presence of hypoalbuminemia (OR 3.3, CI 1.5-7.1, P < 0.01), invasive devices (OR 5.8, CI 3.0-11.4, p < 0.01) and neutropenia (OR 4.1, CI 1.5-11.4, p < 0.01) predict the development of infections.

INTRODUCCIÓN: La prevalencia de microorganismos multirresistentes es un problema de salud pública que continúa creciendo a lo largo del mundo. Existe una población principalmente susceptible de ser colonizada y posteriormente infectarse, son los pacientes oncológicos. OBJETIVO: Identificar las características clínicas y patológicas de los pacientes oncológicos y su relación con la infección con microorganismos productores de BLEE y EPC. PACIENTES Y MÉTODOS: Se condujo un estudio retrospectivo y de carácter analítico entre el primero de enero de 2019 y el 30 de junio de 2020 en tres unidades hemato-oncológicas. RESULTADOS: Incluyó a 3.315 pacientes, de los cuales 217 (6,5%) se encontraban colonizados por microorganismos productores de BLEE y EPC; de éstos, 106/217 (48,8%) presentaron al menos un episodio de infección. El microorganismo más frecuentemente aislado fue Klebsiella pneumoniae, en 29/106 (27,4%). De los infectados, 18/106 (17%) presentaron infección por el mismo microorganismo colonizador. La mucositis (p = 0,002), edad mayor a 65 años (p = 0,041), hipoalbuminemia (p < 0,01), neutropenia (p < 0,01) y la presencia dispositivos invasivos (p < 0,01) demostraron una relación con el desarrollo de infección. CONCLUSIÓN: La presencia de hipoalbuminemia (OR 3,3, IC 1,5-7,1, p < 0,01), dispositivos invasivos (OR 5,8, IC 3.0-11,4, p < 0,01) y neutropenia (OR 4,1, IC 1,5-11,4, p < 0,01) predicen el desarrollo de infecciones.
