    Abstract:
    OBJECTIVE: Interferon-α (IFNα) therapy has been an integral part of the current treatment for hepatitis B virus (HBV) infection. However, the exact effect of IFNα antiviral therapy on liver function and iron metabolism in patients with chronic hepatitis B (CHB) remains unclear. Here, we investigated the characteristics of changes in liver function and iron metabolism indexes in patients with chronic hepatitis B before and after IFNα treatment. Additionally, we determined their predictive value for the therapeutic response of IFNα treatment. METHODS: In this study, 34 patients with CHB before and after IFNα treatment were enrolled. Serum levels of virological indicators, liver function, and iron metabolism markers were detected and analyzed in each patient. ROC curve analysis was performed to compare the predictive value of serum liver function and iron metabolism markers for the therapeutic response of IFN α treatment. RESULTS: A significant decrease in serum HBV DNA (P<0.001) and HBsAg (P<0.001) was observed before and after IFNα treatment. Compared to the patients before IFNα treatment, patients after IFNα treatment showed a significant increase in serum albumin (ALB) (P<0.05) and a significant decrease in serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) (P=0.003 and P=0.034). These findings suggested that the synthetic function of the liver was improved, and liver inflammation was alleviated. Serum HEPC and serum ferritin (SF) levels in patients after IFNα treatment were significantly higher (P<0.001, P<0.001); however, serum iron (SI) levels were significantly lower (P=0.005) than those in patients before IFNα treatment. These findings indicate that IFNα treatment regulated iron metabolism homeostasis in CHB patients. Combined liver function and iron metabolism markers, including ALB, SI, SF, and HEPC, had the highest predictive value for the therapeutic response of IFNα treatment for CHB. CONCLUSION: IFNα treatment improved liver function and iron metabolism homeostasis in patients with CHB. Regular monitoring of serum ALB, SI, SF, and HEPC can help predict the therapeutic response of IFNα treatment for CHB.
