摘要: 目的 探讨应用腹水多形核白细胞计数(PMN)联合全身免疫炎症指数(SII)和血清C反应蛋白(CRP)/白蛋白(ALB)比值预测失代偿期肝硬化患者并发自发性细菌性腹膜炎(SBP)的价值。方法 2021年4月~2025年4月我院收治的失代偿期肝硬化患者80例,常规检测血和腹水常规,检测血生化和血清C-反应蛋白(CRP),计算SII和CRP/ALB比值,采用Logistic回归分析和受试者工作特征曲线(ROC)评估各指标及其联合预测SBP发生的效能。结果 在本组80例失代偿期肝硬化患者中,诊断SBP者31例(38.8%);SBP组肝功能Child-Pugh C级、肝性脑病和上消化道出血占比或发生率分别为51.6%、22.6%和45.2%,均显著高于非SBP组(分别为10.2%、0.0%和0.0%,P<0.05);SBP组凝血酶原时间、血清白蛋白水平和外周血白细胞计数分别为(14.3±3.1) s、(29.7±0.5) g/L和(9.8±2.6)×109/L,与非SBP组【分别为(12.9±2.9) s、(36.9±8.1) g/L和(7.1±1.9)×109/L】比,差异显著(P<0.05);SBP组腹水PMN为(270.2±70.4)×106/L,显著高于非SBP组【(25.6±6.9)×106/L,P<0.05】,SII为(284.1±41.7),显著高于非SBP组【(221.7±28.9),P<0.05】,血清CRP/ALB比值为(0.7±0.2),显著高于非SBP组【(0.4±0.1),P<0.05】;Logistic回归分析显示,腹水PMN、SII和CRP/ALB比值均是影响失代偿期肝硬化患者并发SBP的危险因素(P<0.05); ROC曲线分析显示,以腹水PMN联合SII或CRP/ALB比值诊断SBP的灵敏度为94.8%,特异度为98.0%。结论 单纯依靠腹水PMN诊断失代偿期肝硬化患者并发SBP可能存在临床漏诊,而联合SII或CRP/ALB比值可提高诊断效能。

Abstract: Objective The aim of this study was to explore the predictive efficacy of ascites polymorphonuclear leucocyte (PMN) counts and systemic immune-inflammation index (SII) and serum C-reactive protein (CRP)/albumin (ALB) ratio for spontaneous bacterial peritonitis (SBP) in patients with decompensated liver cirrhosis. Methods 80 patients with decompensated liver cirrhosis were admitted to our hospital between April 2021 and April 2025, blood and ascites routine, blood biochemical and serum CRP levels were obtained clinically, and SII and CRP/ALB ratio were calculated. The predictive efficacy was analyzed by using multivariate Logistic regression and receiver operating characteristic (ROC) curves. Results Of the 80 patients with decompensated liver cirrhosis, SBP was diagnosed in 31 cases(38.8%); percentage of Child-Pugh class C, hepatic encephalopathy and varices bleeding in SBP group were 51.6%, 22.6% and 45.2%, all much higher than 10.2%, 0.0% and 0.0% (P<0.0) in non-SBP group; prothrombin time, serum albumin levels and peripheral white blood cell counts in SBP group were (14.3±3.1) s, (29.7±0.5) g/L and (9.8±2.6)×109/L, all significantly different as compared to [(12.9±2.9) s,(36.9±8.1) g/L and (7.1±1.9)×109/L, respectively, P<0.05] in non-SBP group; ascites PMN count, SII and CRP/ALB ratio in patients with SBP were (270.2±70.4)×106/L, (284.1±41.7) and (0.7±0.2), all significantly higher than [(25.6±6.9)×106/L,(221.7±28.9) and (0.4±0.1), respectively, P<0.05] in those without; Logistic regression analysis showed that ascites PMN, SII and CRP/ALB ratio were all the independent risk factors for SBP occurrence (P<0.05); ROC analysis demonstrated that the sensitivity was 94.8% and the specificity was 98.0%, when ascites PMN was combined with SII or CRP/ALB ratio in predicting SBP complicated. Conclusion SII and/or CRP/ALB ratio is helpful in preventing underdiagnosis of SBP in patients with decompensated liver cirrhosis, if ascites PMN counts is alone relied on.
