BACKGROUND: Sequential or combined treatment with nucleos(t)ide analogs (NAs) and pegylated interferon alpha-2b (Peg-IFN-α-2b) can improve the clinical cure rate. However, its clinical application is limited due to the adverse reactions associated with IFN.
METHODS: A multi-center prospective observational study was conducted involving 59 NAs-treated chronic hepatitis B (CHB) patients who were treated with a combination therapy of NAs and Peg-IFN-α-2b for 48 weeks. Another 327 NAs-treated patients received NAs monotherapy for 48 weeks. At the end of the treatment, patients were classified into either the clinically cured group or the non-clinically cured group based on clinical efficacy. The study aimed to analyze the clinical cure rate and the predictive factors.
RESULTS: After propensity score matching (PSM), a total of 104 patients were included in the exposure and the control groups. After 48 weeks of treatment, 13 patients in the exposed group achieved clinical cure, with a cure rate of 25%. In contrast, in the control group was 1.92%. The clinical cure rate was greater in the population with CHB or compensated cirrhosis treated with sequential or combined Peg-IFN-α-2b and NAs than in the control group (p < 0.001). Patients treated with Peg-IFN-α-2b were divided into a clinical cure group and a non-clinical cure group for single-factor regression and multi-factor binary logistic regression. The results showed that baseline qHBsAg [relative ratio (RR) = 0.997, 95%CI: [0.995, 0.999], p = 0.031] and △TBiL (RR = 0.698, 95%CI: [0.555, 0.879], p = 0.002) were independent influencing factors for achieving clinical cure in patients with CHB or compensated cirrhosis.
CONCLUSION: A lower baseline qHBsAg and decrease in TBiL at 24 weeks of treatment are independent influencing factors for achieving clinical cure. The lower the baseline qHBsAg and the higher the △TBiL levels after 24 weeks of treatment, the higher the probability of patients achieving clinical cure.
