[Short-term prognostic predictive value of the neutrophil/lymphocyte ratio combined with prognostic nutritional index in hepatitis B virus-related acute-on-chronic liver failure].

Objective: To explore the prognostic predictive value of neutrophil/lymphocyte ratio (NLR) combined with prognostic nutritional index (PNI) in patients with hepatitis B virus-related acute-on-chronic liver failure (HBV-ACLF). Methods: Clinical data from 149 HBV-ACLF patients admitted to the infectious diseases Department of the General Hospital of Ningxia Medical University were retrospectively analyzed. Demographic data of the enrolled patients and the initial clinical-related data after admission were collected. Patients were divided into survival (93 cases) and death groups (56 cases) according to their prognostic condition 90 days after discharge. Demographic and clinical differences were compared between the two groups data. Receiver operating characteristic (ROC) curves were plotted to determine the optimal cutoff values for NLR and PNI in predicting the 90-day mortality rate of HBV-ACLF patients. The COX regression model was used to conduct univariate and multivariate analyses to investigate the correlation between NLR and PNI and the prognosis of HBV-ACLF patients. Kaplan-Meier survival analysis was used to explore the effects of NLR and PNI on the survival of HBV-ACLF patients. Results: The death group NLR was higher than that of the survival group, while the PNI was lower than that of the survival group, with a statistically significant difference. The area under the receiver operating characteristic curve (0.842, 95% CI: 0.779-0.906) showed patients with adverse prognosis assessed by NLR combined with PNI had a superior prognosis than that of the Model for End-Stage Liver Disease (MELD) and its combined serum sodium (MELD-Na) and Child-Turcotte-Pugh (CTP) scores. COX regression analysis showed that NLR≥3.03 and MELD score were independent risk factors affecting the prognosis of HBV-ACLF patients. PNI > 36.13 was a protective factor for evaluating the prognosis of HBV-ACLF patients. Conclusion: NLR combined with PNI can enhance the prognostic predictive value of HBV-ACLF.目的： 探讨中性粒细胞/淋巴细胞比值（NLR）联合预后营养指数（PNI）对乙型肝炎病毒相关慢加急性肝衰竭（HBV-ACLF）患者预后的预测价值。 方法： 回顾性分析宁夏医科大学总医院感染性疾病科收治的149例HBV-ACLF患者的临床相关资料。收集入组患者的人口学资料和入院后首次临床相关资料，根据患者出院后90 d的疾病转归情况将患者分为生存组（93例）和死亡组（56例），比较2组人口学资料和临床资料的差异。绘制受试者操作特征（ROC）曲线，确定NLR和PNI预测HBV-ACLF患者90 d病死率的最佳截断值。通过COX回归模型进行单因素和多因素分析，探讨NLR和PNI与HBV-ACLF患者预后的关系。采用Kaplan-Meier生存分析探讨NLR和PNI对HBV-ACLF患者生存期的影响。 结果： 死亡组的NLR高于生存组，而PNI低于生存组，差异有统计学意义。ROC曲线显示NLR联合PNI评估HBV-ACLF患者不良预后的受试者操作特征曲线下面积（0.842，95%CI：0.779~0.906）大于终末期肝病模型（MELD）及其联合血清钠（MELD-Na）及Child-Turcotte-Pugh（CTP）评分。COX回归分析显示NLR≥3.03和MELD评分是影响HBV-ACLF患者预后的独立危险因素。而PNI > 36.13是评估HBV-ACLF患者预后的保护性因素。 结论： NLR联合PNI可提高对HBV-ACLF预后的预测价值。.
