目的 觀察阿德福韋酯聯合胸腺五肽治療乙型肝炎病毒e抗原(HBeAg)陽性慢性乙型肝炎2年的療效。 方法 2007年1月-2009年1月間178例慢性乙型肝炎患者隨機分為試驗組91例和對照組87例。試驗組給予胸腺五肽1 mg,隔日皮下注射,療程52周;同時阿德福韋酯10 mg/d口服104周。對照組給予阿德福韋酯10 mg/d,口服104周。治療26、52、104周及停藥52周時,分別檢測血清丙氨酸氨基轉移酶(ALT)、天冬氨酸氨基轉移酶(AST)、乙型肝炎病毒(HBV)DNA含量及HBV血清標志物。 結果 治療52周后,試驗組在ALT復常率、AST復常率、HBV DNA轉陰率、HBeAg轉陰率與HBeAg/HBeAb血清轉換率方面都比對照組高。停藥52周時,試驗組與對照組的ALT復常率、AST復常率、HBV DNA轉陰率、HBeAg轉陰率、HBeAg/HBeAb血清轉換率分別為74.73%與51.72%、75.82%與54.02%、25.27%與8.05%、26.37%與10.34%、18.68%與8.05%(χ2=10.652、9.313、9.421、7.574、4.313,P<0.05)。 結論 阿德福韋酯聯合胸腺五肽治療HBeAg陽性慢性乙型肝炎比單獨使用阿德福韋酯抗病毒治療效果更好,有助于提高HBeAg/HBeAb血清轉換率,減少停藥后病毒學突破,并且使用安全。Objective To evaluate the efficacy of adefovir dipivoxil (ADV) combined with thymopentin on chronic hepatitis B patients with positive hepatitis B e antigen (HBeAg). Methods Between January 2007 and January 2009, 178 chronic hepatitis B patients with positive HBeAg were randomly divided into two groups: the treatment group (91 cases) and the control group (87 cases). All patients in two groups received 10 mg of ADV once a day for 104 weeks, while the patients in the treatment group received 1 mg of thymopentin for subcutaneous injection every other day for 52 weeks. The rates of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) normalization, serum hepatitis B virus (HBV) DNA clearance and HBeAg loss and anti- HBeAg seroconversion were evaluated at pretreatment, and 52, 104 and 156 weeks after treatment, respectively. Results After 52-week treatment, The rates of ALT and AST normalization, serum HBV DNA clearance and HBeAg loss and anti- HBeAg seroconversion in the treatment group were higher than those in the control group. In 52-week follow-up after 104 weeks treatment, the rates of ALT and AST normalization , serum HBV DNA clearance and HBeAg loss and anti- HBeAg seroconversion of two groups were 74.73% versus 51.72%, 75.82% versus 54.02%, 25.27% versus 8.05%, 26.37% versus 10.34%, 18.68% versus 8.05%, respectively (χ2 = 10.652, 9.313, 9.421, 7.574, 4.313; P<0.05). Conclusions It is more effective for adefovir dipivoxil combined with thymopentin on HBeAg-positive patients with chronic hepatitis B than using adefovir alone. Combination treatment could improve the rates of HBeAg seroconversion and reduce the breakthrough of HBV after drug withdrawal. And it is safe.
目的 評估替比夫定與阿德福韋酯聯合治療優化阿德福韋酯單藥治療應答不佳的陽性慢性乙型肝炎患者的療效。 方法 選擇2008年6月-2009年8月間共26例阿德福韋酯治療至少12個月且病毒學應答不佳的乙型肝炎病毒e抗原(HBeAg),陽性的慢性乙型肝炎患者,在10 mg阿德福韋酯治療的基礎上,加用600 mg替比夫定。肝功能和乙型肝炎病毒(HBV) DNA每3個月評估1次,乙型肝炎兩對半和腹部B型超聲每半年評估1次。 結果 在第1年的治療期間,所有患者血清HBV DNA水平均呈進行性下降,其中24例(92.3%)血清HBV DNA水平在聯合治療12個月時低于檢測值下限,有25例(96.2%)患者丙氨酸轉氨酶水平復常。治療6個月時,分別有7例(26.9%)和2例(7.7%)患者發生HBeAg消失和血清學轉換;治療12個月時,分別有11例(42.3%)和8例(30.8%)患者發生HBeAg消失和血清學轉換。整個治療期間,26例患者均未出現病毒學突破。 結論 阿德福韋酯單藥治療應答不佳時,加用替比夫定可有效控制病毒,使患者獲得較好的病毒學、生化學和免疫學應答。Objective To evaluate the curative efficacy of telbivudine combined with defovir dipivoxil on positive-HBeAg chronic hepatitis B patients with suboptimal response to adefovir dipivoxil. Methods A total of 26 HBeAg-positive patients with suboptimal response to adefovir dipivoxil (treated with adefovir dipivoxil for more than 12 months) were treated with adefovir dipivoxil 10 mg in addition to telbivudine 600 mg between June 2008 and August 2009. Liver function and serum hepatitis B virus (HBV) DNA tests were assessed at the baseline and 3-month intervals, whereas HBV serological markers and abdominal ultrasonography were carried out every 6 months. Results During the first year of treatment, all patients showed a progressive decline of serum HBV DNA levels; while undetectable serum HBV DNA and normalization of alanine aminotransferase was achieved in 24(92.3%) and 25 (96.2%) patients, respectively, at the end of the first year of treatment. The 6- and 12-month cumulative rates of HBeAg loss were 26.9% (7/26) and 42.3% (11/26), respectively; and corresponding cumulative rates of HBeAg/anti-HBe seroconversion were 7.7% (2/26) and 30.8 (8/26), respectively. During the observation period, no virological breakthrough was detected. Conclusion Telbivudine combined with defovir dipivoxil may be a good choice for patients with suboptimal response to adefovir dipivoxil, which could induce effective viral inhibition and help patients obtain more virological, biochemical and immunological responses.
目的 探討乙型肝炎病毒(HBV)表面抗原(HBsAg)陽性肝硬化患者血清中HBV前S1抗原(前S1抗原)、HBV e抗原(HBeAg)及HBV核酸定量檢測(HBV DNA)相關性。 方法 2008年7月-2011年5月對97例HBsAg陽性肝硬化住院患者和50份HBsAg陰性的健康體檢者血清進行前S1抗原、HBV血清標志物檢測及實時熒光定量PCR檢測HBV DNA結果進行分析。 結果 97份HBsAg陽性肝硬化患者血清中,前S1抗原、HBeAg及HBV DNA陽性率分別為53.6%(52/97)、22.7%(22/97)及61.8%(60/97)。22例HBeAg陽性血清中,前S1抗原陽性18例(81.8%), HBV DNA陽性20例(90.9%)。75例HBeAg陰性血清中,前S1抗原陽性34例(45.3%),HBV DNA陽性40例(53.3%),兩者的前S1抗原與HBV DNA結果間都具有很好的相關性。HBV DNA含量與前S1抗原及HBeAg陽性結果顯示:HBsAg陽性的肝硬化患者血清中HBV DNA陰性率為38.1%(含量<103 copies/mL),而陽性檢出率HBV DNA含量主要集中在103~105 copies/mL,占81.7%(49/60),HBV DNA含量>105 copies/mL占18.3%(11/60)。 結論 HBsAg陽性的肝硬化患者血清中主要以HBV非HBeAg陽性血清學模式為主,HBV DNA陽性檢出率的含量主要集中在103~105 copies/mL。前S1抗原在HBeAg陽性血清中與其含有HBsAg病毒及HBeAg陽性患者具有很好的相關性,而在HBeAg陰性血清中存在著差異。Objective To study the correlation among Pre-S1 antigen, HBeAg and HBV DNA results in patients with HBsAg-positive liver cirrhosis. Methods We retrospectively analyzed the serum pre-S1-antigen, HBV serum markers and real-time quantitative PCR HBV DNA results in 97 patients with HBsAg-positive liver cirrhosis and 50 HBsAg-negative healthy volunteers in our hospital from July 2008 to May 2011. Results Among the 97 samples of HBsAg-positive liver cirrhosis patients’ serum, the positive rates of Pre-S1 antigen, HBeAg and HBV DNA were 53.6% (52/97), 22.7% (22/97) and 61.8% (60/97), respectively. In the 22 samples of HBeAg-positive serum, the number of positive pre-S1 antigen and HBV DNA was 18 (81.8%) and 20, respectively. In the 75 samples of negative HBeAg serum, the number of positive pre-S1 antigen and HBV DNA was 34 (45.3%) and 40 (53.3%) respectively. The pre-S1 antigen was correlated well with HBV DNA results in both the two groups. HBV DNA level, pre-S1 antigen and HBeAg-positive results showed that the serum HBV DNA negative rate of HBsAg-positive patients with cirrhosis was 38.1% (<103 copies/mL), while the positive rate of HBV DNA level was mainly concentrated at 103~105 copies/mL, accounting for 81.7% (49/60), and HBV DNA level over 105 copies/mLaccounted for only 18.3% (11/60). Conclusions HBsAg-positive patients with cirrhosis mainly have a serum non-HBeAg-positive HBV serology pattern, and HBV DNA positive rate of the content is mainly concentrated at 103~105 copies/mL. There is a good correlation between pre-S1 antigen in HBeAg-positive serum and patients with HBsAg virus or positive HBeAg, while for Pre-S1 antigen in HBeAg-negative serum, it is quite different.
