目的在日本，人口结构老龄化日趋明显，社会全面老龄化似乎已经不远了，这表明需要医疗保健的人口不断增加。克雷伯氏菌属是医疗保健相关感染的主要病原体，其重要性正在增加。本研究的目的是阐明克雷伯菌属的特征。通过评估由克雷伯氏菌引起的胸部感染特征的差异来确定胸部感染。和肺炎。方法我们对因克雷伯氏菌引起的肺炎、肺脓肿/坏死性肺炎和脓胸住院的连续患者进行了回顾性研究。和肺炎链球菌在我们位于日本埼玉的机构工作了 15 年。患者因克雷伯菌属导致胸部感染的患者。（K 组，n=76）和 S。包括肺炎链球菌（S组，n=446）。结果与S组相比，K组男性、年龄较大、合并铜绿假单胞菌、糖尿病、上消化系统手术史、饮酒习惯、吸烟习惯和病前体能状态受损的频率更高。K组肺脓肿或坏死性肺炎（31.6% vs. 0.9%）和脓胸无肺实质阴影（3.9% vs. 0.7%）的百分比高于S组。入院严重程度和死亡率在各组之间没有差异；然而，与S组相比，K组患者需要更长的抗生素给药时间和住院时间。结论克雷伯氏菌属。与肺炎球菌感染相比，胸部感染具有一些显着特征，我们的结果有助于区分克雷伯菌属。由肺炎球菌感染引起的感染。

Comparison between Patients with Chest Infection due to Klebsiella spp. and Streptococcus pneumoniae

Objective In Japan, the aging demographic structure is becoming pronounced, and the full-blown graying of society appears not far off, which indicates an increasing population that will require healthcare contact. Klebsiella spp. are major pathogens in healthcare-associated infections, and their importance is increasing. The aim of this study was to clarify the characteristics of Klebsiella spp. chest infections by evaluating the differences in the characteristics of chest infections caused by Klebsiella spp. and pneumoniae. Methods We conducted a retrospective study of consecutive patients hospitalized with pneumonia, lung abscess/necrotizing pneumonia, and empyema due to Klebsiella spp. and S. pneumoniae for 15 years at our institution in Saitama, Japan. Patients Patients with chest infections due to Klebsiella spp. (K group, n=76) and S. pneumoniae (S group, n=446) were included. Results The K group more frequently was male, older, coinfected by Pseudomonas aeruginosa, and had diabetes mellitus, a history of upper digestive system surgery, alcohol drinking habit, a smoking habit, and an impaired premorbid performance status than the S group. The percentages of lung abscesses or necrotizing pneumonia (31.6% vs. 0.9%) and empyema without pulmonary parenchymal shadow (3.9% vs. 0.7%) were higher in the K group than those in the S group. Severity on admission and mortality did not differ between the groups; however, patients in the K group required a longer duration of antibiotics administration and hospital stay than those in the S group. Conclusion Klebsiella spp. chest infections have some marked characteristics when compared with pneumococcal infections, and our results serve to differentiate Klebsiella spp. infection from pneumococcal infection.
