Objective To investigate the effect of anti-liver fibrosis Chinese patent drugs on renal hypofunction associated with alcoholic liver disease( ALD). Methods A retrospective analysis was performed for 592 patients with ALD who were admitted to Beijing Ditan Hospital,Capital Medical University,from August 1,2008 to March 1,2016,and according to whether they were treated with Fuzheng Huayu capsules,Anluo Huaxian pills,or Fufang Biejia Ruangan tablets for ≥180 cumulative defined daily doses,they were divided into Chinese medicine group and control group. After propensity score matching at a ratio of 1 ∶ 1,two groups were obtained with 187 patients in each group. Related data were recorded,including medical history,drinking amount,routine blood test results,liver and renal function,coagulation,and abdominal imaging findings. The t-test was used for comparison of normally distributed continuous data between groups,and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups; the chi-square test was used for comparison of categorical data between groups; the Kaplan-Meier method was used to compare the cumulative incidence rate of renal hypofunction between two groups. Results There were no significant differences between the two groups in age,drinking amount,proportion of patients with hypertension or diabetes,baseline aspartate aminotransferase,estimated glomerular filtration rate,uric acid,and prothrombin time,and the patients were followed up for 36 months( range 23-54 months). Uric acid( hazard ratio [HR]= 1. 003,95% confidence interval [CI]: 1. 001-1. 005,P = 0. 001),prothrombin time( HR = 1. 103,95% CI: 1. 034-1. 177,P = 0. 003),and red cell volume distribution width( HR = 1. 024,95% CI: 1. 011-1. 038,P < 0. 001) were independent risk factors for renal hypofunction in patients with ALD,and anti-liver fibrosis Chinese patent drug was an independent protective factor against renal hypofunction( HR = 0. 170,95% CI: 0. 053-0. 552,P = 0. 003). The Chinese medicine group had a significantly lower incidence rate of renal hypofunction than the control group( 16. 6 % vs 32. 1 %,χ2= 10. 263,P = 0. 001). The subgroup analysis of the patients in the Chinese medicine group showed that Chinese medicine treatment for > 24 months had the best effect( HR = 0. 210,95 % CI: 0. 084-0. 525,P = 0. 001). Compared with the control group,the Chinese medicine group had a significantly longer time to the onset of renal hypofunction( 36 months vs24 months,Z =-2. 652,P = 0. 008). Conclusion Anti-liver fibrosis Chinese patent drugs can reduce the incidence rate and delay the onset of renal hypofunction in patients with ALD.
