Adding the immune‑boosting peptide thymosin‑alpha‑1 (thymalfasin) to the standard antiviral drug entecavir helped patients with chronic hepatitis B show lower liver enzymes, better immune cell counts, and reduced markers of liver scarring compared to entecavir alone.

To observe and analyse the clinical effects of entecavir on serum hyaluronic acid (HA), laminin (LN), and type IV collagen (IVC) in patients with hepatitis B e-antigen (HBeAG)-positive chronic hepatitis B during clinical treatment. The patients in the control group received clinical treatment with entecavir monotherapy, while those in the observation group underwent thymalfasin + entecavir combination therapy. The clinical curative effects of immune checkpoint inhibitors at different concentrations on diseases were compared from all aspects. There were lower levels of total bilirubin (TBIL) and alanine transaminase (ALT) in the observation group, a more satisfactory improvement in immune function-related indicators, and lower levels of HA, LN, and IVC in the observation group, which were statistically different between the two groups (P<0.05). The levels of liver function indicators, immune function-related indicators (CD3+, CD4+, CD8+, CD4+/CD8+, CD4+/CD8+), and HA, LN and IVC were not statistically different between the two groups before treatment. Entecavir is highly effective in the clinical treatment of HBeAG-positive chronic hepatitis B. However, entecavir + thymalfasin combination therapy can alleviate the clinical symptoms. In this way, liver fibrosis can be prevented in patients with HBeAG-positive chronic hepatitis B, and the clinical curative effect can be enhanced.
