Long-term outcomes of add-on adefovir dipivoxil therapy to ongoing lamivudine in patients with lamivudine-resistant chronic hepatitis B

Aim: Add-on adefovir dipivoxil (ADV) therapy has been a standard rescue treatment for patients with lamivudine (LAM)-resistant chronic hepatitis B, but the overall benefits of long-term add-on ADV therapy are still limited. The aim of this study was to evaluate the long-term efficiency of add-on ADV treatment and to explore predictive factors associated with it. Methods: A total of 158 patients with LAM-resistant chronic hepatitis B were included in this retrospective, multicenter, nationwide study in Japan. After confirming LAM resistance, ADV was added to LAM treatment. Three types of events were considered as outcomes: virological response, hepatitis B e antigen (HBeAg) clearance and alanine aminotransferase (ALT) normalization. Virological response was defined as serum hepatitis B virus (HBV) DNA levels of less than 3 log copies/mL. Baseline factors contributing to these outcomes were examined by univariate and multivariate analyses. Results: The median total duration of ADV treatment was 41 months (range, 6–84). The rate of virological response was 90.8% at 4 years of treatment; HBeAg clearance and ALT normalization were achieved by 34.0% and 82.7%, respectively, at the end of follow up. Each outcome had different predictive factors: baseline HBV DNA and albumin level were predictive factors for virological response, history of interferon therapy and ALT level for HBeAg clearance, and sex and baseline albumin level for ALT normalization. Conclusion: Long-term add-on ADV treatment was highly effective in LAM-resistant chronic hepatitis B patients in terms of virological and biochemical responses. Lower HBV replication and lower albumin level at baseline led to better outcomes.     

阿德福韦酯初治与挽救治疗拉米夫定耐药的慢性乙型肝炎观察

目的观察阿德福韦酯初治与拉米夫定治疗耐药后联合阿德福韦酯治疗慢性乙型肝炎患者的疗效。方法将45例入选患者分为两组,其中A组为拉米夫定治疗耐药后加用阿德福韦酯治疗组,B组为阿德福韦酯初治组。治疗前及治疗后12、24、36、48周均检测肝功能、肾功能、HBV DNA载量。结果在治疗12、24周时,A组患者的HBV DNA低于检测下限的比率明显高于B组,差异有统计学意义;治疗48周时,两组HBV DNA载量变化、低于检测下限的比率、ALT复常率的差异均无统计学意义。在治疗期间两组患者的肾功能均正常,均未发现不良反应。结论阿德福韦酯初治与联合拉米夫定治疗拉米夫定耐药后慢性乙型肝炎患者同样有效,值得继续探索。

Adefovir plus lamivudine are more effective than adefovir alone in lamivudine-resistant HBeAg- chronic hepatitis B patients: A 4-year study

Background and Aim:  Adefovir dipivoxil (ADV) is effective in lamivudine (LAM)-resistant hepatitis B e antigen-negative (HBeAg^-) chronic hepatitis B (CHB). However, it is unclear whether LAM treatment should be continued in these patients. We aimed to compare the long-term efficacy of adding ADV to ongoing LAM treatment versus switching to ADV monotherapy in LAM-resistant HBeAg^- CHB.
Methods:  Sixty LAM-resistant patients with HBeAg^- CHB were randomly assigned (3:1) to combination therapy (10 mg ADV once daily plus ongoing LAM at 100 mg once daily [ n  = 45]) or 10 mg ADV monotherapy once daily ( n  = 15). Virological and biochemical responses were defined as hepatitis B virus (HBV)–DNA <400 copies/mL and as normalization of alanine aminotransferase levels, respectively.
Results:  The median follow-up time was 53 months (range 20–60 months). A virological response was observed in 38/45 (84.4%) and 11/15 (73.3%) patients in the ADV/LAM and ADV monotherapy groups, respectively ( P  = 0.56). Biochemical response rates were higher in the ADV/LAM group than in the ADV monotherapy group (90.9% vs 57.1%, respectively; P  = 0.01). In the ADV/LAM group, serum HBV–DNA remained undetectable in all patients who achieved a virological response ( n  = 38). In the ADV monotherapy group, virological breakthrough occurred in four of the 11 patients who achieved a virological response (36.4%; P  < 0.001 vs the ADV/LAM group, log–rank test). In addition, two patients in each group who did not achieve a virological response eventually developed ADV resistance.
Conclusions:  Adding ADV to LAM is more effective than switching to ADV monotherapy in LAM-resistant patients with HBeAg^- CHB.     

Efficacy of adefovir dipivoxil in the treatment of lamivudine-resistant hepatitis B virus genotype C infection.

BACKGROUND AND AIMS: Adefovir dipivoxil (ADV) is a nucleotide analogue that is known to be effective for lamivudine-resistant hepatitis B virus (HBV) mutants as well as wild-type HBV. The aim of this study is to assess the efficacy of ADV against lamivudine-resistant genotype C HBV mutants. METHODS: Thirty-five patients with breakthrough hepatitis due to lamivudine-resistant HBV received ADV 10 mg daily with discontinuation of lamivudine. Quantitative HBV DNA, HBeAg, liver function test including alanine aminotransferase (ALT) was checked every 4-12 weeks to evaluate the efficacy of ADV. RESULTS: ADV was administered for a median of 48 weeks (range: 24-120 weeks). The rate of serum HBV DNA loss was 68.6%, 80.0%, 84.0%, and 88.2% at weeks 12, 24, 36, and 48, respectively. The rate of serum HBeAg seroconversion was 8.3% and 14.3% at weeks 24 and 48, respectively. The rate of serum ALT normalization at week 48 was 70.6%. Within 32 weeks after stopping ADV therapy, serum HBV DNA levels increased to a median of 378.9 pg/ml in 88.9% of patients, who were treated for a median of 40 weeks. Moreover, in some patients, the ALT level increased to more than five times the upper limit of normal. CONCLUSIONS: Administration of ADV is an effective option for the treatment of patients with lamivudine-resistant genotype C HBV infection.

目的研究阿德福韦酯联合双环醇片治疗慢性乙型肝炎的疗效和安全性。方法选择125例曾应用拉米夫定治疗的慢性乙型肝炎患者,随机分2组接受治疗。试验组63例,每日口服阿德福韦酯10mg,同时每日服用双环醇片75mg;对照组62例,仅给予每日口服阿德福韦酯10mg。2组均连续用药48周。观察治疗前后血清氨基转移酶水平及病毒学指标方面的改变。结果2组血清氨基转移酶均明显下降,试验组更为显著(P<0.05或<0.01)。试验组HBV DNA阴转率(58.7%)显著高于对照组(40.3%),P<0.05;HBeAg阴转率(31.8%)显著高于对照组(16.1%),P<0.05;HBeAg血清转换率(19.1%)虽高于对照组(11.3%),但差异无统计学意义。2组均未发生与研究药物相关的不良反应。结论阿德福韦酯与双环醇片联合应用治疗慢性乙型肝炎在肝功能及病毒学方面取得较好疗效且安全。     

Factors associated with the virological response of lamivudine-resistant hepatitis B virus during combination therapy with adefovir dipivoxil plus lamivudine

Background The aim of this study was to investigate the factors associated with the response of lamivudine-resistant hepatitis B virus (HBV) during combination therapy with adefovir dipivoxil plus lamivudine. Methods Sixty-three patients with breakthrough hepatitis received a 10-mg once-daily dose of oral adefovir dipivoxil. Results The rates of undetectable serum HBV-DNA were 49.2% after 24 weeks, 61.9% after 48 weeks, and 67.2% after 72 weeks. The cumulative hepatitis B e antigen (HBeAg) loss rates in patients with alanine aminotransferase (ALT) levels of more than twice the upper limit of normal (ULN) were significantly higher than in patients with ALT less than twice the ULN (P = 0.0145). Multivariate analysis revealed that baseline ALT level (P = 0.003) and HBeAg status (P = 0.049) were associated with early virological response. Conclusions Baseline ALT level was associated with HBeAg loss and seroconversion, and baseline ALT level and HBeAg status were associated with the virological response of lamivudine-resistant HBV during combination therapy with adefovir dipivoxil plus lamivudine.
