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.
