Objective: To summarize the clinical features of patients with Klebsiella pneumoniae pyogenic liver abscess(KP-PLA). Methods: Clinical data of 133 patients with pyogenic liver abscess(PLA) and positive results of blood or pus culture were retrospectively analyzed in Huashan Hospital Affiliated to Fudan University from 2009 to 2018. According to the culture results, patients were divided into KP-PLA group (n=92) and non-KP-PLA group (n=41). Results: KP-PLA and non-KP-PLA were similar in gender composition with males accounting for 67.39% and 70.73%, and had age of (56.8±13.8) years and (55.0±13.0) years (χ(2)=0.146, 0.708, P>0.05) respectively. The underlying diseases were more common in KP-PLA group, including diabetes accounting for 45.65% and 24.39%, and hypertension accounting for 32.61% and 14.63% (χ(2)=5.384, 4.642, P<0.05) respectively. Patients with KP-PLA had more invasive infections beyond liver than those with non-KP-PLA, which were 27.17% and 9.76% (χ(2)=5.046, P=0.025). The laboratory results showed that hemoglobin levels in KP-PLA and non-KP-PLA were (109.88±20.97) g/L and (97.75±20.25) g/L (t=3.086, P=0.002). Serum alkaline phosphatase levels were 146.50 (114.50, 237.50) U/L and 220.50 (120.00, 316.75) U/L in KP-PLA and non-KP-PLA (U=2 239.500, P=0.048) patients. Conclusions: KP-PLA mainly develops in middle-aged and elderly men, especially those with diabetes and hypertension. Patients with KP-PLA need to be paid more attention for invasive manifestations beyond liver.
目的： 总结肺炎克雷伯菌肝脓肿（Klebsiella pneumoniae pyogenic liver abscess，KP-PLA）的临床特点。 方法： 临床回顾性研究，收集2009—2018年复旦大学附属华山医院血培养或脓液培养阳性的133例细菌性肝脓肿住院患者临床资料，根据病原学结果分为KP-PLA（92例）和非KP-PLA组（41例）。 结果： KP-PLA组和非KP-PLA组均以男性（分别占67.39%、70.73%，χ(2)=0.146）和中老年[年龄分别为（56.8±13.8）岁和（55.0±13.0）岁，t=0.708]患者多见（P值均>0.05）。KP-PLA组患者有糖尿病和高血压的比例（45.65%和32.61%）高于非KP-PLA组（24.39%和14.63%），χ(2)值分别为5.384、4.642，P值均<0.05。KP-PLA组发生肝脏以外脏器的侵袭性感染比非KP-PLA组更常见（27.17%比9.76%，χ(2)=5.046，P=0.025）。实验室检查结果显示KP-PLA组和非KP-PLA组血红蛋白[（109.88±20.97）g/L比（97.75±20.25）g/L]差异有统计学意义（t=3.086，P=0.002）；碱性磷酸酶[146.50（114.50，237.50）U/L比220.50（120.00，316.75）U/L]差异有统计学意义（U=2 239.500，P=0.048）。 结论： KP-PLA好发于男性中老年患者，尤其是有糖尿病和高血压基础疾病的人群。KP-PLA患者需要警惕有无肝外转移性感染灶，即侵袭综合征表现。.
