Ren H, Huang Y. Effects of pegylated interferon-α based therapies on functional cure and the risk of hepatocellular carcinoma development in patients with chronic hepatitis B. J Viral Hepat 2019; 26 Suppl 1:5-31. [PMID: 31380584 DOI: 10.1111/jvh.13150] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/28/2018] [Accepted: 05/15/2009] [Indexed: 12/23/2022]
Abstract
Chronic hepatitis B virus (HBV) infection continues to pose a serious global health threat and a significant socio-economic burden in many areas of the world. Almost all current clinical practice guidelines on the management of chronic hepatitis B (CHB) infection recommend that eligible patients pursue the optimal treatment endpoint, which is defined as HBsAg loss with or without anti-HBs seroconversion. This review describes the effects of various regimens containing pegylated interferon (peg-IFN)-alpha on functional cure and the outcome of hepatocellular carcinoma (HCC) in patients with CHB. Peg-IFN-α monotherapy is a treatment option recommended by local and international clinical practice guidelines to help more CHB patients achieve a sustained off-treatment virological response, which is particularly appropriate for relatively young patients who demand a finite treatment approach. Peg-IFN-α add-on or sequential therapy in patients who have achieved a suppressed viral load after nucleos(t)ide analog (NA) therapy may offer further benefits on HBeAg seroconversion and HBsAg decline, although the effects of de novo combination therapy with peg-IFN-α and NAs on long-term outcomes remain unclear. Evaluation of baseline and on-treatment predictors is useful for selecting the patients who are likely to achieve additional benefits. Furthermore, some recent studies have shown that peg-IFN-α-based therapy results in better prevention of HBV-related hepatocellular carcinoma (HCC), especially in high-risk patients.

Abstract
PURPOSE This study aims to investigate the antiviral effect of polyethylene glycol (PEG)-interferon α-2a and PEG-interferon α-2b treatment on hepatitis B e antigen (HBeAg)-positive chronic hepatitis B (CHB) at the 48th week of treatment and the 24th and 48th week after withdrawal, in order to provide guidance on the antiviral treatment of HBeAg-positive CHB patients. MATERIAL AND METHODS Antiviral treatment was performed on 155 HBeAg-positive CHB patients. Among these patients, 66 patients received PEG-interferon α-2a treatment and 89 patients received PEG-interferon α-2b treatment; and these treatments were administered by subcutaneous injection, once per week, which lasted for 48 weeks. Other antiviral and hepatoprotective drugs were not used during the treatment. RESULTS At the 48th week of treatment, ALT recovery rate, HBsAg seroconversion rate, HBeAg seroconversion rate and HBV DNA titers dropped below 200 IU/mL rate were 69.7%, 6.1%, 27.3% and 50.0%, respectively, in the PEG-interferon α-2a group; and were 70.8%, 6.7%, 33.7% and 62.9%, respectively, in the PEG-interferon α-2b group. At the 24th and 48th week of follow-up after withdrawal, HBsAg seroconversion rate in these two groups did not change; and HBeAg seroconversion rate further increased. Furthermore, HBV DNA revealed a low recurrence rate. The difference between these two groups was not significantly significant. CONCLUSIONS PEG-interferon α-2a and PEG-interferon α-2b are effective antiviral drugs for the treatment of HbeAgpositive CHB, which has a HBsAg seroconversion rate of more than 5%. Furthermore, this sustained response effect was maintained at the 24th and 48th week of follow-up after withdrawal.

The Efficacy of Add-on Telbivudine Versus Switching to Pegylated Interferon Alfa-2a in Chronic Hepatitis B Patients With Poor Responses to Adefovir. HEPATITIS MONTHLY 2016; 16:e31278. [PMID: 27110255 PMCID: PMC4834190 DOI: 10.5812/hepatmon.31278] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 07/05/2015] [Revised: 10/10/2015] [Accepted: 11/21/2015] [Indexed: 12/11/2022]
Abstract
BACKGROUND There are limited options for chronic hepatitis B (CHB) patients who have poor responses to adefovir (ADV). OBJECTIVES The aim of this study is to evaluate the effects of adding on telbivudine (LdT) or switching to pegylated interferon alfa-2a (PEG-IFN-α2a) as alternative rescue therapies for patients with poor responses to the initial ADV treatments. PATIENTS AND METHODS Ninety-seven CHB patients with HBV DNA > 2 log10 copies/mL 48 weeks after ADV monotherapy were included in this study. Fifty-nine of these patients were treated with a combination of LdT plus ADV (LdT + ADV) daily, while thirty-eight patients were switched to PEG-IFN-α2a subcutaneous injections weekly for 48 weeks. RESULTS Both rescue strategies were proven to be safe and the majority of patients tolerated the therapies well. LdT + ADV led to more rapid reductions in viral loads than PEG-IFN-α2a monotherapy, with 2.14 (LdT + ADV) and 0.98 (PEG-IFN-α2a) log10 copies/mL decreases 48 weeks after rescue treatments, respectively (P < 0.00001). The rates corresponding to virological and biochemical responses were also elevated in patients who received the LdT + ADV combination therapy at the end of the observation period (88.1 vs. 68.4% for virological response, P = 0.017; 83.3 vs. 47.2%, P = 0.00045). However, the decline in the hepatitis B surface antigen (HBsAg) was more pronounced in PEG-IFN-α2a treated patients. Moreover, the cumulative rates of serological responses were higher in patients who switched to the PEG-IFN-α2a therapy. CONCLUSIONS Both add-on LdT and switching to PEG-IFN-α2a were satisfactory and optimal treatments for CHB patients with poor responses to ADV. Both rescue strategies resulted in significant reductions in serum viral load and ALT levels, and were associated with high rate of serological outcomes in our hospital.

Chen J, Zhang DH, Xu CR, Zhu MY, Yang ZT, Gong QM, Yu DM, Zhang XX. Quantitative hepatitis B surface antigen combined with hepatitis B e antigen as sustained virological response predictors during extended therapy with Peginterferon alfa-2a for hepatitis B e antigen-positive chronic hepatitis B. J Clin Virol 2015; 72:88-94. [PMID: 26476325 DOI: 10.1016/j.jcv.2015.09.012] [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: 02/26/2015] [Revised: 09/24/2015] [Accepted: 09/30/2015] [Indexed: 10/22/2022]
Abstract
BACKGROUND The best strategy for chronic hepatitis B patients with poor response to 48 weeks of Peginterferon-based therapy has been controversial and the predictive value of hepatitis B surface antigen (HBsAg), hepatitis B e antigen (HBeAg) and hepatitis B virus (HBV) DNA levels for determining the sustained virological response (SVR) of these patients is uncertain. OBJECTIVES To optimize management of these patients and evaluate the use of these serobiomarkers to predict SVR. STUDY DESIGN Eighty-one patients with an unsatisfactory response after 48 weeks of Peginterferon-based therapy were treated with extended Peginterferon therapy with or without nucleo(s) tide analogues (NAs), for a total of 96 weeks of Peginterferon treatment. HBsAg, HBeAg and HBV DNA levels were measured serially during the treatment and follow-up. RESULTS AND CONCLUSIONS Twenty-six of 81 patients (32.1%) attained SVR during the 72-week follow-up. The SVR rate was not statistically different between groups receiving 1-year prolongation of Peginterferon with or without NAs. The serum HBsAg cut-off of 1800IU/mL at week 48 had area under curve (AUC) of 0.727, and the serum HBsAg cut-off of 1500IU/mL, combined with HBeAg loss at week 72, had AUC of 0.753 to predict SVR during the follow-up. In conclusion, extended treatment with Peginterferon with or without NAs for patients with unsatisfactory response after 48 weeks of Peginterferon-based therapy is a promising strategy to achieve SVR, and quantitative serum HBsAg at week 48 and HBsAg level combined with HBeAg loss at week 72 of therapy can predict SVR to prolongation therapy with Peginterferon.
