• W4287522433 abstract "Clostridioides difficile infection (CDi) is one of the foremost hospital-acquired infections. We present an observational study aimed to describe the incidence, epidemiology, and clinical outcome of CDi in a tertiary university hospital in Buenos Aires. The episodes, diagnosed in 117 consecutive adult patients in the period 01/01/2017 to 01/04/2020, were distributed in three groups: 63 (53.9%) were classified as hospital-acquired infections (HA), 25 (21.4%) as community onset-health care-associated infections (CO-HCA) and 29 (24.8%) as community-associated infections (CA). The incidence of HA CDi infections was 3.1, 5. 2 and 2.8 every 10 000 patient days in 2017, 2018 and 2019, respectively. The microbiological diagnosis was made by immunochromatography with antigen GDH and C. difficile toxin positive in 51 episodes (43.6%) and by GDH positive, toxin negative and PCR positive in 66 episodes (56.4%). Older age (p = 0.018), chronic kidney disease (p = 0.013), immunosuppression (p = 0.021), and higher comorbidity Charlson score (p = 0.001) were observed in patients with IH and CA-HCA infections. No significant differences in clinical features were found among groups. During the hospital st ay, 13 patients (11.1%) required admission to the intensive care unit. Ten recurrences occurred, representing 8.5% of CDI episodes. The 90-day mortality was 19.8%, being significantly higher in HA and CO-HCA infections (p = 0.014). Our findings highlight both the local burden of CDi morbidity and mortality and the need for the implementation of preventive strategies.La infección por Clostridioides difficile (ICD) es una de las más importantes infecciones intrahospitalarias. Se realizó un estudio observacional que describe la incidencia, las características epidemiológicas y la evolución clínica de la ICD en un hospital universitario de la Ciudad de Buenos Aires. Los episodios, diagnosticados en 117 pacientes adultos consecutivos entre el 01/01/2017 y el 01/04/2020, fueron clasificados en ICD intrahospitalaria (IH) en 63 (53.9%), de inicio comunitario y asociada al ámbito de la salud (ICAAS) en 25 (21.4%) y comunitaria (CO) en 29 (24.8%) pacientes. La incidencia de ICD IH fue 3.1, 5.2 y 2.8 cada 10 000 días paciente en 2017, 2018 y 2019, respectivamente. El diagnóstico microbiológico se realizó mediante inmunocromatografía con glutamato deshidrogenasa y toxina positivas en 51 (43.6%) y mediante glutamato deshidrogenasa positiva, toxina negativa y PCR positiva en 66 (56.4%). Los pacientes con ICD IH e ICAAS presentaron mayor edad (p = 0.018), mayor frecuencia de insuficiencia renal crónica (p = 0.013) e inmunosupresión (p = 0.021) y mayor puntaje en índice Charlson de comorbilidad (p = 0.001). No hubo diferencia significativa en la forma de presentación clínica entre los tres grupos. Durante la evolución de la ICD, 13 (11.1%) pacientes requirieron internación en terapia intensiva. Se registraron 10 recurrencias, que correspondieron al 8.5% de los episodios de ICD. La mortalidad a los 90 días fue 19.8%, significativamente mayor en los pacientes con ICD IH e ICAAS (p = 0.014). Estos hallazgos destacan la considerable carga de morbilidad de la ICD y la necesidad de implementar estrategias preventivas." @default.
