摘要:
目的 探讨肝硬化合并胸水患者胸水再发的独立危险因素并建立预测模型。 方法 收集2014年4月至2019年12月入住传染科的肝硬化合并大量胸水病例190例,经治疗胸水均消退,随访患者胸水再发情况。将其是否胸水再发分为无胸水再发组(n = 161)和胸水再发组(n = 29),收集2组的性别、年龄、血常规、肝功能、血生化、彩超、置管时间等行Logistic单因素和多因素回归分析,并建立预测模型,绘制AUROC曲线验证模型的敏感性、特异性。 结果 190例患者中,经治疗胸水消失后再发29例(15%),将190例患者基线的年龄、性别、血常规、肝功能等因素行Logistic回归分析,血小板(OR = 1.018,P = 0.028)、血肌酐(OR = 0.978,P = 0.024)、门静脉流速(OR = 0.660,P = 0.048)、置管时间(OR = 1.801,P < 0.001)是肝硬化患者胸水再发的独立危险因素。4个危险因素和模型的AUC分别为:0.673、0.619、0.831、0.969、0.977,模型的敏感性、特异性和正确率分别为89.7%、92.9%、91.8%。 结论 肝硬化合并胸水患者胸水再发预测模型能准确地预测胸水再发风险,对影响因素的早期干预,能减少肝硬化患者胸水再发,并为医务人员及时采取预防性管理措施提供参考。 Abstract:Objective To explore the independent risk factors of the recurrence of pleural effusion in patients with liver cirrhosis and complicated with pleural effusion and to establish a predictive model. Methods 190 cases of liver cirrhosis complicated with massive pleural effusion and admitted to the department of infectious diseases from April 2014 to December 2019 were inquired. The recurrence of pleural effusion after the treatment was followed up, and the relevant clinical data and laboratory indexes were collected. The patients were divided into non pleural effusion recurrence group (n = 161) and pleural effusion recurrence group (n = 29) and ROC curve was used to verify the prediction efficiency of the prediction model. Results Among the 190 patients, 29 (15%) recurred after the disappearance of pleural effusion after the treatment. The factors such as baseline age, gender, blood routine and liver function of 190 patients were analyzed by logistic regression. Platelet (or = 1.018), blood creatinine (or = 0.978), portal vein velocity (or = 0.660) and catheterization time (or = 1.801) were independent risk factors for the recurrence of pleural effusion in patients with liver cirrhosis. The AUC of the four risk factors and the model were 0.673, 0.619, 0.831, 0.969 and 0.977 respectively. The sensitivity, specificity and accuracy of the model were 89.7%, 92.9% and 91.8% respectively. Conclusion The prediction model of pleural effusion recurrence in patients with liver cirrhosis and combined with pleural effusion could better predict the risk of pleural effusion recurrence.Early intervention of influencing factors could reduce the recurrence of pleural effusion in patients with liver cirrhosis, and provide the reference for medical staff to take the preventive management measures in time. -
