Abstract:
OBJECTIVE To analyze the efficacy of polyethylene glycol (Peg)-interferon antiviral therapy for chronic hepatitis B virus (HBV) infection with normal alanine transaminase (ALT) and the effect on the status of peripheral blood T cells, to provide references for the treatment of chronic HBV infection with normal ALT.
METHODS The medical records of 95 patients with chronic HBV infection and normal ALT admitted to the infection department of Cangzhou Central Hospital and Cangzhou Infectious Disease Hospital from Jan. 2020 to Dec. 2023 were retrospectively analyzed, and were divided into the Peg-interferon treated group (59 cases) and the conventionally treated group (36 cases). The general data and clinical efficacy in the two groups were collected and compared, and the serum ALT, aspartate aminotransferase (AST), hepatitis B surface antigen (HBsAg), hepatitis B e antigen (HBeAg) and HBV DNA were detected and recorded in the two groups before and after 48 weeks of treatment, CD4+ and CD8+ T cells were also analyzed by flow cytometry.
RESULTS HBsAg clearance rate, negative conversion rate of HBeAg and HBV DNA in PEG-interferon treated group was higher than that in conventionally treated group (22.03% vs. 2.78%, 93.22% vs. 52.78%, 100.00% vs. 77.78%, respectively, P < 0.05). At 48 weeks of treatments, serum HBsAg, HBeAg, HBV DNA levels decreased in both groups, and decreased markedly in the Peg-Interferon treated group when compared with the conventionally treated group (P < 0.05); meanwhile, the level of CD4+ decreased and CD8+ elevated in both groups, the changes in CD4+ and CD8+ levels were significant in the Peg-interferon treated group when compared with the conventionally treated group (P < 0.05). The levels of serum ALT and AST of the two groups of patients were elevated after the treatment for 48 weeks (P < 0.05).
CONCLUSION The efficacy of Peg-interferon antiviral treatment for chronic HBV-infected patients with normal ALT is remarkable, which can reduce the severity of liver damage and improve the immunity and antiviral efficacy of patients.
