摘要:
目的 探讨IL-32联合终末期肝病模型(MELD)对HBV相关慢加急性肝衰竭(HBV-ACLF)患者预后的预测价值。 方法 选取2015年1月-2018年12月在苏州大学附属第一医院住院的92例HBV-ACLF患者,根据确诊后3个月随访情况分为存活组(n=40)和死亡组(n=52)。采用酶联免疫吸附试验(ELISA)测定患者的血清IL-32水平。收集患者的临床资料,包括年龄、性别、合并基础疾病、主要并发症、WBC、PLT、红细胞比积(HCT)、TBil、ALT、AST、Alb、SCr、PT、INR、HBV DNA等。符合正态分布的计量资料2组间比较采用t检验,不符合正态分布的计量资料2组间比较采用Mann-Whitney U检验;计数资料2组间比较采用χ2检验;IL-32与其他变量进行Pearson相关性分析;采用二元logistic回归分析影响HBV-ACLF患者预后的独立危险因素;利用ROC曲线下面积(AUC)评价IL-32联合MELD评分对HBV-ACLF预后的预测价值,AUC的比较采用正态性Z检验。 结果 2组间HCT、PLT、TBil、SCr、PT、INR、HBV DNA、IL-32、MELD评分比较差异均有统计学意义(P值均<0.05);IL-32与TBil(r=0.952, P<0.001)、MELD评分(r=0.850, P<0.001)均呈显著正相关; IL-32(OR=1.137, 95%CI: 1.040~1.243, P=0.005)和MELD评分(OR=1.055,95%CI:1.001~1.109,P=0.025)是HBV-ACLF患者死亡的独立危险因素; IL-32联合MELD评分对HBV-ACLF患者预后的预测价值最高(AUC=0.992, 95%CI:0.981~1.000),优于IL-32(AUC=0.984)和MELD评分(AUC=0.877),差异均具有统计学意义(Z值分别为2.265、3.182, P值均<0.05)。 结论 IL-32、MELD评分均能预测HBV-ACLF患者预后,两者联合则预测价值更高。 Abstract:Objective To investigate the value of interleukin-32 (IL-32) combined with Model for End-Stage Liver Disease (MELD) in predicting the prognosis of patients with hepatitis B virus (HBV)-related acute-on-chronic liver failure (HBV-ACLF). Methods A total of 92 patients with HBV-ACLF who were hospitalized in The First Affiliated Hospital of Soochow University from January 2015 to December 2018 were enrolled, and according to the follow-up results at 3 months after diagnosis, the patients were divided into survival group with 40 patients and death group with 52 patients. ELISA was used to measure the serum level of IL-32. Clinical data of the patients were collected, including age, sex, underlying diseases, major complications, white blood cell count (WBC), platelet count (PLT), hematocrit (HCT), total bilirubin (TBil), alanine aminotransferase (ALT), aspartate aminotransferase (AST), albumin (Alb), serum creatinine (SCr), prothrombin time (PT), international normalized ratio (INR), and HBV DNA. The t-test was used for comparison of normally distributed continuous data between two groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups; the chi-square test was used for comparison of categorical data between two groups; a Pearson correlation analysis was performed for IL-32 and other variables; a binary logistic regression analysis was performed to investigate the independent risk factors for the prognosis of patients with HBV-ACLF. The receiver operating characteristic(ROC) curve(AUC) was used to evaluate the value of IL-32 combined with MELD score in predicting the prognosis of patients with HBV-ACLF. The normal Z test was used for comparison of AUC. Results There were significant differences between the two groups in HCT, PLT, TBil, SCr, PT, INR, HBV DNA, IL-32, and MELD score (all P < 0.05). IL-32 was positively correlated with TBil (r=0.952, P < 0.001) and MELD score (r=0.850, P < 0.001). IL-32 (odds ratio [OR]=1.137, 95% confidence interval [CI]: 1.040-1.243, P=0.005) and MELD score (OR=1.055, 95% CI: 1.001-1.109, P=0.025) were independent risk factors for the death of HBV-ACLF patients. IL-32 combined with MELD score had the highest value in predicting the prognosis of patients with HBV-ACLF (AUC=0.992, 95% CI: 0.981-1.000), with a significantly higher AUC than IL-32 (0.992 vs 0.984, Z=2.265, P < 0.05) and MELD score (0.992 vs 0.877, Z=3.182, P < 0.05). Conclusion Both IL-32 and MELD score can predict the prognosis of patients with HBV-ACLF, and the combination of these two indicators has a better predictive value. -
