- Abstract: Objective To determine the serum level of quantitative hepatitis B core antibody(qAnti-HBc)in decompensated hepatitis B cirrhosis patients with normal international normalized ratio(INR),and to investigate its prognostic value in this target population.Methods A total of 120 decompensated hepatitis B cirrhosis patients with normal INR who were diagnosed and treated in Tianjin Third Central Hospital from October 1,2018 to April 1,2021 were enrolled.Baseline indicators were collected,the serum level of qAnti-HBc was measured,and the prognosis was followed up.According to the prognosis,the patients were divided into survival group and death group.The independent-samples t test or the Mann-Whitney U test was used for comparison of continuous data between two groups,and the chi-square test was used for comparison of categorical data between groups.Univariate and multivariate Cox regression analyses were used to investigate the candidate variables affecting the prognosis and establish a prognostic model for this population,and the receiver operating characteristic(ROC)curve was plotted.Results The patients enrolled were followed up for 32.17±13.09 months,and there were 99 patients(82.5%)in the survival group and 21 patients(17.5%)in the death group.There were significant differences between the survival group and the death group in sex(χ2=2.151,P=0.014),age(t=-3.218,P=0.003),total bilirubin(Z=-0.901,P=0.027),albumin(t=3.353,P=0.001),and Child-Pugh class(χ2=1.144,P=0.010).The univariate and multivariate Cox regression analyses showed that serum qAnti-HBc(hazard ratio[HR]=0.57,95%confidence interval[CI]:0.32-1.00,P=0.043),age(HR=1.06,95%CI:1.00-1.12,P=0.044),sex(HR=3.82,95%CI:1.46-10.00,P=0.006),platelet count(HR=0.98,95%CI:0.97-1.00,P=0.037),and albumin(HR=0.86,95%CI:0.79-0.95,P=0.002)were independent risk predictive factors for the prognosis of decompensated hepatitis B cirrhosis patients with normal INR.Based on these factors,a predictive model was established as h(t,x)/h0(t)=exp(1.34X1+0.06X2-0.14X3-0.02X4-0.57X5),where X1=sex,X2=age,X3=albumin,X4=platelet count,X5=qAnti-HBc.This predictive model had an area under the ROC curve of 0.842,with a sensitivity of 0.79,a specificity of 0.73,and a C-index of 0.85.Conclusion In decompensated hepatitis B cirrhosis patients with normal INR(0.8-1.2),serum qAnti-HBc is one of the independent risk predictive factors for death,and the predictive model established based on the combination of serum qAnti-HBc and other indicators can effectively predict the prognosis of patients.
