Community-acquired Clostridium difficile infection (CA-CDI) is a growing concern. CA-CDI differs from hospital-acquired C. difficile infection (HA-CDI) in its epidemiology, risk factors, severity, and outcomes. In this study, we investigated C. difficile infections in a tertiary care hospital in Seoul, Korea, and compared the CA-CDI and HA-CDI cases diagnosed in the same period. Total 593 cases were confirmed as CDI in 2014, of which CA-CDI accounted for 68 (11.5%) of the total CDI cases. Compared with HA-CDI, the mean age of CA-CDI cases was lower than that of HA-CDI (42.7 vs 60.4). In CA-CDI, antibiotic and proton pump inhibitor (PPI) use in the 12 preceding weeks and concurrent chemotherapy and tube feeding were less frequent compared with HA-CDI. In most cases (63/68, 92.6%), patients with CA-CDI recovered without any complications or recurrence. The most prevalent C. difficile type in CA-CDI cases was PCR-ribotype 012, accounting for 18.3% of the total, followed by PCR-ribotype 018 (16.7%).

社区获得性艰难梭菌感染 (ca-cdi) 日益受到关注。Ca-cdi与医院获得性艰难梭菌感染 (ha-cdi) 的流行病学、危险因素、严重程度和结局不同。在这项研究中,我们调查了韩国首尔一家三级医院的艰难梭菌感染,并比较了同期诊断的ca-cdi和ha-cdi病例。共593例确诊为CDI 2014年,其中ca-cdi占CDI病例总数的68 (11.5%)。与ha-cdi相比,ca-cdi病例的平均年龄低于ha-cdi (42.7 vs 60.4)。在ca-cdi中,与ha-cdi相比,前12周使用抗生素和质子泵抑制剂 (PPI) 以及同时进行化疗和管饲的频率较低。在大多数情况下 (63/68,92.6%),CA-CDI患者恢复无任何并发症或复发。CA-CDI病例中最普遍的艰难梭菌类型是PCR核型012,占总数的18.3%,其次是PCR核型018 (16.7%)。
