Long-term effects of peginterferon-based therapy versus nucleos(t)ide analogue monotherapy in non-cirrhotic HBeAg-positive chronic hepatitis B patients. Antiviral Res 2025; 240:106192. [PMID: 40403849 DOI: 10.1016/j.antiviral.2025.106192] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/02/2025] [Revised: 05/07/2025] [Accepted: 05/19/2025] [Indexed: 05/24/2025]
Abstract
BACKGROUND & AIMS The long-term clinical benefits of interferon (IFN)-based therapy compared to nucleos(t)ide analogue (NA) monotherapy in HBeAg-positive chronic hepatitis B (CHB) have not been well defined. This study aimed to evaluate the cumulative incidence of new-onset cirrhosis, serological responses, and hepatocellular carcinoma (HCC) development between these treatment strategies. METHODS Two independent cohorts of non-cirrhotic, HBeAg-positive CHB patients were analyzed: a treatment-naïve cohort (n = 686) and an NA-experienced cohort (n = 531). Patients received either IFN-based therapy or NA monotherapy. Propensity score matching (PSM) was employed to minimize intergroup heterogeneity. The primary endpoint was the cumulative incidence of new-onset cirrhosis. RESULTS After PSM, the 10-year cumulative incidence of new-onset cirrhosis was significantly lower in the IFN-based therapy group compared to the NA monotherapy group in both the treatment-naïve (3.3 % vs 20.0 %, p = 0.005) and NA-experienced (4.9 % vs 20.9 %, p = 0.034) cohorts. IFN-based therapy also resulted in significantly higher serological response rates across both cohorts, including HBeAg loss (treatment-naïve: 84.7 % vs 55.6 %; NA-experienced: 60.4 % vs 43.6 %, both p < 0.001) and HBsAg loss (treatment-naïve: 14.3 % vs 5.7 %, p = 0.006; NA-experienced: 10.2 % vs 1.3 %, p < 0.001). Subgroup analysis showed that patients receiving IFN-based therapy who achieved HBeAg loss within 96 weeks had the greatest long-term benefits, with lower cirrhosis incidence and higher HBsAg loss rates. Although the incidence of HCC was lower in the IFN-based group, the difference did not reach statistical significance (both p > 0.05). CONCLUSIONS IFN-based therapy provides superior long-term benefits over NA monotherapy in reducing cirrhosis risk and enhancing serological responses in HBeAg-positive CHB patients.

Abstract
Aims/Background Hepatitis B virus (HBV) infection poses a challenge to global healthcare. Peginterferon alfa-2b (PEG-IFNα-2b) is an effective treatment for HBV infection. This study aimed to explore the efficacy of PEG-IFNα-2b combined with entecavir in the treatment of HBV infection, its effect on liver function and immune factors, and the risk factors affecting the prognosis of patients with HBV infection. Methods The clinical data of 184 patients with HBV infection who were treated at Jinhua Central Hospital from January 2021 to January 2024 were collected for retrospective analysis. Patients were divided into a control group (not receiving antiviral treatment, n = 34), a standard treatment group (receiving entecavir, n = 85), and a combination treatment group (PEG-IFNα-2b and entecavir, n = 65) according to the treatment approach. Treatment efficacy, liver function indicators (albumin [ALB], alanine aminotransferase [ALT], and aspartate aminotransferase [AST]), immune factor indexes (tumour necrosis factor alpha [TNF-α] and interferon gamma [IFN-γ]), hepatitis B surface antigen [HBsAg] and HBV DNA levels were compared among the three groups. All patients were followed up after treatment. According to their prognosis, the patients were divided into good prognosis group (n = 118) and poor prognosis group (n = 66). Logistic regression analysis was performed to explore the risk factors affecting the prognosis of HBV patients. Results The efficacy in the combination treatment group was higher (92.31%) than that in the control group (8.82%) and the standard treatment group (78.82%) (p < 0.05). After treatment, the HBsAg and HBV DNA levels were decreased in the standard treatment and combination treatment groups (p < 0.05). Compared with the control and standard treatment groups, the combination treatment group exhibited significantly lower HBsAg and HBV DNA levels after treatment (p < 0.05). Besides, the combination treatment group had lower ALT and AST levels (p < 0.05), and higher ALB level (p < 0.05), than the control and standard treatment groups after treatment. Compared with the control and standard treatment groups, the combination treatment group demonstrated decreased TNF-α level and higher IFN-γ level after treatment (p < 0.05). Multivariate logistic regression analysis identified family medical history as the risk factor affecting the prognosis of patients with HBV infection (p = 0.001, odds ratio [OR] = 3.614, 95% confidence interval [CI]: 1.685-7.750) and therapy regimen as the protective factor (p = 0.029, OR = 0.135, 95% CI: 0.022-0.815). Conclusion The PEG-IFNα-2b combination therapy in patients with HBV infection significantly improves the clinical treatment efficacy, liver function, and immune factors. In addition, this study found that therapy regimen and family medical history are independent factors affecting the prognosis of HBV infection.

Effects of Different Antiviral Treatments on Liver Inflammation and Fibrosis in Patients With Chronic Hepatitis B. J Viral Hepat 2025; 32:e70019. [PMID: 40087906 DOI: 10.1111/jvh.70019] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/19/2024] [Revised: 01/19/2025] [Accepted: 02/14/2025] [Indexed: 03/17/2025]
Abstract
Oral nucleotide analogues (NAs) and peginterferon-α injections are commonly used for the treatment of patients with chronic hepatitis B (CHB). This study aims to evaluate the effects of different antiviral therapies on the degree of liver inflammation and fibrosis in CHB patients. This was a retrospective cohort study. A total of 101 CHB patients were admitted to the Liver Center of Xiamen Hospital of Traditional Chinese Medicine from 2017 to 2021 and were divided into three groups for different antiviral treatments: NAs therapy group (n = 36), peginterferon-α therapy group (n = 38) and nonantiviral therapy group (n = 27). The differences in degrees of liver inflammation and liver fibrosis between two histopathologic biopsies before and after treatment were analysed and compared to evaluate the efficacy of different treatments. The degrees of liver inflammation and liver fibrosis were improved after NAs or peginterferon-α therapy. In terms of improving the degree of liver inflammation, peginterferon-α therapy (74%) and NAs therapy (44%) were better than nonantiviral therapy (11%, p < 0.05), although no significant difference was shown between peginterferon-α therapy and NAs therapy (p = 0.974). For liver fibrosis improvement, peginterferon-α therapy showed significantly better efficacy than NAs therapy (68% vs. 33%, p = 0.044), while NAs therapy was better than nonantiviral therapy (33% vs. 11%, p = 0.028). Peginterferon-α and NAs can significantly improve the degree of liver inflammation and liver fibrosis in CHB patients. Peginterferon-α is superior to NAs in delaying and reversing liver fibrosis. This study provides a new basis for peginterferon-α therapy to prevent progression of fibrosis in CHB patients.

Early clinical efficacy of pegylated interferon treatment in patients with different phases of chronic HBV infection: A real-world analysis. J Viral Hepat 2022; 30:427-436. [PMID: 36562258 DOI: 10.1111/jvh.13792] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/30/2022] [Revised: 12/12/2022] [Accepted: 12/14/2022] [Indexed: 12/24/2022]
Abstract
Although there are therapeutic advantages for hepatitis B virus (HBV) withpegylated interferon alpha (peg-IFNα) treatment compared with nucleos(t)ide analog (NAs) therapy, the effect difference in infected population at different phases has not been well established. We studied the clinical efficacy of peg-IFNα in two populations with HBV infection, including inactive HBsAg carrier (IHC) and chronic hepatitis B (CHB). A total of 328 HBV-infected patients were included in this real-world analysis. Patients were divided into two groups according to the infected stages. Peg-IFNα monotherapy or combination therapy with NAs were used in IHCs, and peg-IFNα added-on NAs therapy was applied to patients with CHB. The primary efficacy endpoint was HBsAg loss at Week 24. Results: The Kaplan-Meier cumulative rates of HBsAg loss were 39.50% (n = 47/119) in IHC group and 28.71% (n = 60/209) in CHB group at Week 24 (p < .05). After Propensity Score Matching (PSM), the HBsAg loss rates were 36.84% (n = 35/95) and 32.63% (n = 31/95), respectively (p > .05). Patients with baseline HBsAg level < 100 IU/ml achieved higher rates of HBsAg clearance in IHC and CHB group (before PSM: 47.44% vs. 42.86%, after PSM: 49.12% vs. 45.83%, all p values > .05). Baseline HBsAg level and its level decline from baseline to Week 12 can be as the predictors for HBsAg loss at Week 24 in both groups. Hence, the efficacy of HBsAg clearance was broadly similar between IHCs and NA-treated CHB patients during the early peg-IFNα therapy. A significant downward trend of HBsAg level was observed in both groups during peg-IFNα therapy.

Abstract
Hepatic metastases are a poor prognostic factor of colorectal carcinoma (CRC) and new strategies to reduce the risk of liver CRC colonization are highly needed. Herein, we used mouse models of hepatic metastatization to demonstrate that the continuous infusion of therapeutic doses of interferon-alpha (IFNα) controls CRC invasion by acting on hepatic endothelial cells (HECs). Mechanistically, IFNα promoted the development of a vascular antimetastatic niche characterized by liver sinusoidal endothelial cells (LSECs) defenestration extracellular matrix and glycocalyx deposition, thus strengthening the liver vascular barrier impairing CRC trans-sinusoidal migration, without requiring a direct action on tumor cells, hepatic stellate cells, hepatocytes, or liver dendritic cells (DCs), Kupffer cells (KCs) and liver capsular macrophages (LCMs). Moreover, IFNα endowed LSECs with efficient cross-priming potential that, along with the early intravascular tumor burden reduction, supported the generation of antitumor CD8+ T cells and ultimately led to the establishment of a protective long-term memory T cell response. These findings provide a rationale for the use of continuous IFNα therapy in perioperative settings to reduce CRC metastatic spreading to the liver.

Liver Int 2021; 41:2032-2045. [PMID: 33896094 DOI: 10.1111/liv.14897] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/13/2020] [Revised: 02/27/2021] [Accepted: 03/31/2021] [Indexed: 12/15/2022]
Abstract
BACKGROUND & AIMS The effectiveness and safety of peginterferon alpha (peg-IFN-α) monotherapy in inactive hepatitis B virus (HBV) carriers (IHCs) have not been fully evaluated. METHODS This observational study prospectively enrolled 298 IHCs in China from 2015 to 2019. Participants were given the right to choose to either receive peg-IFN-α monotherapy (treatment group, n = 142) or be monitored without treatment (control group, n = 156) according to their wishes. The scheduled treatment duration was 48 weeks. All participants were followed up to 72 weeks. The main efficacy endpoint was hepatitis B surface antigen (HBsAg) clearance at 72 weeks. RESULTS Baseline characteristics were similar between both groups. At 72 weeks, intention-to-treat analysis showed that the rates of HBsAg clearance and seroconversion of the treatment group were 47.9% (68/142) and 36.6% (52/142), respectively, which were significantly higher than the HBsAg clearance rate of 1.9% (3/156) and the seroconversion rate of 0.6% (1/156) in the control group (both P < .001). Baseline HBV DNA < 20 IU/mL, lower HBsAg levels at baseline, 12 and 24 weeks, alanine aminotransferase elevation at 12 weeks, and greater HBsAg reduction from baseline to 12 and 24 weeks were independent predictors of HBsAg clearance. Generally, the therapy was well tolerated. Only five participants discontinued therapy as a result of peg-IFNα-related adverse events. CONCLUSIONS Peg-IFN-α monotherapy results in high rates of HBsAg clearance and seroconversion and the treatment is safe for IHCs.
