Abstract:
ObjectiveTo investigate the association of gene mutations in the pre-C, C, and basic core promoter (BCP) regions of hepatitis B virus (HBV) with traditional Chinese medicine (TCM) syndrome types in patients with chronic hepatitis B (CHB). MethodsA retrospective analysis was performed for the clinical data of CHB patients who were diagnosed and treated at the outpatient service and ward of Spleen, Stomach, and Hepatobiliary Department, The First Affiliated Hospital of Henan University of Chinese Medicine, from November 2014 to June 2018. Related clinical data were collected and recorded, including general information, HBV serological markers, HBV gene mutations, and information obtained by four TCM diagnostic methods. Syndrome differentiation and typing were performed for each patient with reference to the criteria for TCM syndrome differentiation of viral hepatitis, and the association of gene mutation in the pre-C, C, and BCP regions of HBV with TCM syndrome types was analyzed. The chi-square test was used for comparison of categorical data between groups, and the Kruskal-Wallis H test was used for comparison of continuous data between multiple or two groups. ResultsA total of 235 patients with CHB were enrolled, among whom 101 had internal retention of damp-heat, 88 had stagnation of liver Qi and spleen deficiency, 17 had blood stasis obstructing the collaterals, 19 had liver-kidney Yin deficiency, and 10 had spleen-kidney Yang deficiency. There were significant differences in sex, age, and course of disease between the patients with different TCM syndrome types (χ2=17.389, H=173.280, H=86.520, all P＜0.01), and there was a significant difference in age between the CHB patients with gene mutations in the pre-C, C and BCP regions of HBV (H=30.150, P＜0.001). There was a significant difference in the distribution of TCM syndrome types between the CHB patients with gene mutations in the pre-C, C and BCP regions of HBV (χ2=58.117, P＜0.001), and internal retention of damp-heat and stagnation of liver Qi and spleen deficiency were major TCM syndrome types accounting for 80.43%. The patients with internal retention of damp-heat tended to have A1762T and G1764A mutations, and those with stagnation of liver Qi and spleen deficiency tended to have G1896A, A1762T, and G1764A mutations; G1764A mutation was often observed in the patients with blood stasis obstructing the collaterals or liver-kidney Yin deficiency, and I97L mutation was often observed in the patients with spleen-kidney Yang deficiency. ConclusionGene mutations in the pre-C, C, and BCP regions of HBV are associated with TCM syndrome types in CHB patients, and internal retention of damp-heat and stagnation of liver Qi and spleen deficiency are the most common TCM syndrome types. I97L mutation is often observed in patients with spleen-kidney Yang deficiency.
