First line nucleos(t)ide analog monotherapy is more cost-effective than combination strategies in hepatitis B e antigen-positive chronic hepatitis B patients in China.

ABSTRACT: BACKGROUND:Nucleos(t)ide analog (NA) in combination with peginterferon (PegIFN) therapy in patients with hepatitis B e antigen (HBeAg)-positive chronic hepatitis B (CHB) shows better effectiveness than NA monotherapy in hepatitis B surface antigen loss, termed "functional cure," based on previous published studies. However, it is not known which strategy is more cost-effective on functional cure. The aim of this study was to analyze the cost-effectiveness of first-line monotherapies and combination strategies in HBeAg-positive CHB patients in China from a social perspective. METHODS:A Markov model was developed with functional cure and other five states including CHB, compensated cirrhosis, decompensated cirrhosis, hepatocellular carcinoma, and death to assess the cost-effectiveness of seven representative treatment strategies. Entecavir (ETV) monotherapy and tenofovir disoproxil fumarate (TDF) monotherapy served as comparators, respectively. RESULTS:In the two base-case analysis, compared with ETV, ETV generated the highest costs with $44,210 and the highest quality-adjusted life-years (QALYs) with 16.78 years. Compared with TDF, treating CHB patients with ETV and NA?-?PegIFN strategies increased costs by $7639 and $6129, respectively, gaining incremental QALYs by 2.20 years and 1.66 years, respectively. The incremental cost-effectiveness ratios were $3472/QALY and $3692/QALY, respectively, which were less than one-time gross domestic product per capita. One-way sensitivity analysis and probabilistic sensitivity analyses showed the robustness of the results. CONCLUSION:Among seven treatment strategies, first-line NA monotherapy may be more cost-effective than combination strategies in HBeAg-positive CHB patients in China.

Project description:BackgroundThe clinical efficacy of nucleos(t)ide analogues (NAs) combined with interferon (IFN) therapy vs. NAs monotherapy for chronic hepatitis B (CHB) remains inconclusive. The aim of this meta-analysis was to determine whether the NAs plus IFN regimen offers synergistic efficacy that justifies the cost and burden of such a combination therapy in CHB patients.MethodsRelated publications covering the period of 1966 to July 2014 were identified through searching MEDLINE, EMBASE, Cochrane library, Chinese Biomedical Literature Database, WANFANG, and CNKI database. A total of 17 studies were enrolled, including 6 in English and 11 in Chinese. Then, we established a final list of studies for the meta-analysis by systematically grading the quality and eligibility of the identified individual studies. We used hepatitis B antigen (HBeAg) loss, HBV-DNA undetectable rate, HBeAg seroconversion, hepatitis B surface antigen (HBsAg) loss, HBsAg seroconversion, and histological score at the end of treatment for efficacy evaluation. A quantitative meta-analysis (Review Manager, Version 5.1.0) was performed to assess the differences between NAs and IFN combination therapy and NAs monotherapy.ResultsOur analysis demonstrated that HBeAg loss (RR = 1.73, 95% CI = 1.32-2.26, p < 0.001), HBV-DNA undetectable rate (RR = 1.58, 95% CI = 1.22-2.04, p < 0.001), HBeAg seroconversion (RR = 1.68, 95% CI = 1.36-2.07, p < 0.001), and HBsAg loss (RR = 2.51, 95% CI = 1.32-4.75, p < 0.001) in the combination therapy group were significantly higher than those in the monotherapy group. However, there were no significant differences in HBsAg seroconversion (RR = 4.25, 95% CI = 0.62-29.13, p = 0.14), sustained virological response rates, and biochemical response rates observed between the two groups. The results showed that the combination therapy group had more improved HBV histology than the NAs monotherapy group (RR = 1.14, 95% CI = 0.93-1.39, p = 0.22).ConclusionsNAs and IFN or Peg-IFN combination therapy had a better efficacy in terms of HBeAg loss, HBV-DNA undetectable rate, HBeAg seroconversion, and HBsAg loss, compared to the NA monotherapy group at the end of treatment; however, there was no significant difference in HBsAg seroconversion between the two regimens.

Project description:BackgroundChronic hepatitis B (CHB) patients have a high virological relapse rate after cessation of nucleos(t)ide analog (NA) treatment, but the clinical outcome remains unclear. This study aimed to investigate the 96-week clinical outcomes and the risk factors for relapse in CHB after cessation of NAs.MethodsThis study was a prospective trial; 74 eligible patients were enrolled. The patients underwent NA cessation and follow-up according to the 2012 Asian Pacific Association for the Study of the Liver Guideline. Symptoms, biochemical (aspartate aminotransferase [AST], alanine aminotransferase [ALT], total bilirubin, urea nitrogen, creatinine), virological data (hepatitis B surface antigen [HBsAg], hepatitis B e antigen [HBeAg], hepatitis B e antibody [HBeAb], hepatitis B virus [HBV] DNA levels), and color Doppler ultrasound examination results were recorded and analysed.ResultsAfter NA cessation, 19 cases were HBsAg-negative without relapse during the 96-week follow-up. Of the 55 cases of HBsAg-positive after cessation, four types of clinical outcomes were observed. Twelve patients had no relapse during the 96-week follow-up (type A, 21.8%), 7 patients underwent virological relapses but spontaneously had a non-virological relapse (type B, 12.7%), 10 patients maintained virological relapse (type C, 18.2%), and 26 patients turned to clinical relapse, received NA retreatment, and achieved ALT normalization and negative conversion of HBV DNA within 12 months (type D, 47.3%). The 2-year overall cumulative rates of virological and clinical relapses were 58.1% and 24.3%, respectively. Independent factors associated with virological relapse were duration of negative HBV DNA, EOT (end of treatment) HBsAg, and original status of HBeAg. The EOT HBsAg was also an independent factor for clinical relapse.ConclusionsThere are four types of clinical outcomes in patients with CHB after cessation of NA treatment. Further research is needed to explore the mechanism of different clinical outcomes. The EOT HBsAg level is an independent factor associated with both virological and clinical relapse.
