This study aimed to investigate the association of serum immunoglobulin and complement levels and liver fibrosis and inflammation stage in CHB patients. A total of 687 patients with CHB who underwent liver biopsy were enrolled. Serum immunoglobulin and complement were measured before liver biopsy, and liver pathological results were recorded. Associations of serum immunoglobulin and complement levels and liver fibrosis and inflammation stage were analysed. C3, C4, IgG and IgG1 had statistically significant differences among different fibrosis and different inflammation groups. Both C3 and C4 negatively correlated with fibrosis and inflammation stage, but IgG and IgG1 showed opposite results. C3, C4, IgG and IgG1 had statistical significance to predict \u2265S2, \u2265S3 and S4, and also had statistical significance to predict \u2265G2, \u2265G3 and G4. The area under curve (AUC) of the combination of C3, C4 and IgG (C3\u2009+\u2009C4\u2009+\u2009IgG) for predicting \u2265S2, \u2265S3 and S4 was 0.640 (95% CI: 0.603, 0.676), 0.674 (95% CI: 0.638, 0.709) and 0.744 (95% CI: 0.710, 0.776), respectively. The AUC of C3\u2009+\u2009C4\u2009+\u2009IgG for predicting \u2265G2, \u2265G3 and G4 was 0.723 (95% CI: 0.688, 0.756), 0.674 (95% CI: 0.638, 0.709) and 0.771 (95% CI: 0.738, 0.802), respectively. C3, C4, IgG and IgG1 are correlated with liver fibrosis and inflammation stage in CHB patients. C3, C4, IgG and IgG1 have diagnostic value for liver fibrosis and inflammation. C3\u2009+\u2009C4\u2009+\u2009IgG may improve diagnostic accuracy.<\/jats:p>","DOI":"10.1111\/jvh.13810","type":"journal-article","created":{"date-parts":[[2023,1,25]],"date-time":"2023-01-25T10:53:28Z","timestamp":1674644008000},"page":"437-447","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":6,"title":["The
