JORGE, Laura et al. Incidence, clinical characteristic and evolution of Clostridioides difficile infection. Medicina (B. Aires) [online]. 2021, vol.81, n.6, pp.931-938. ISSN 0025-7680.

Clostridioides difficile infection (CDi) is one of the foremost hospital-acquired infections. We present an observa tional 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.
