氧化苦参碱治疗慢性乙型病毒性肝炎疗效及其与HBV负荷的关系探讨

目的：研究氧化苦参碱治疗慢性乙型病毒性肝炎疗效及其与HBV负荷的关系。方法：44例慢性乙型肝炎患者，随机分为治疗组（给予氧化苦参碱和一般护肝药物）23例，对照组（仅给予一般护肝药物）21例。以聚合酶链反应（PCR）法一量测定血清HBV水平，分析不同疗效与不同血清HBV负荷的关系。结果：氧化苦参碱肌肉注射慢性乙型肝炎3个月（0.4g/d),HBVDNA及HBeAg转阴率均为43.47%，明显优于对照组（P＜0．05）。治疗后HBVDNA定量水平从10^6.83±1.27copy/ml降至10^3.35±3.08copy/ml，治疗后HBeAg转阴的患者，其治疗前血清HBVDNA定量水平（10^6.30±1.42copy/ml)，明显低于未转阴者（10^7.23±1．23copy/ml)。结论：氧化苦参碱治疗慢性乙型肝炎有效，治疗前血清HBVDNA水平较低者疗效较好。

Relationship between Serum Load of HBV-DNA and Therapeutic Effect of Oxymatrine in Patients with Chronic Hepatitis B

OBJECTIVE: To study the relationship between serum load level of HBV-DNA and therapeutic effect of oxymatrine in patients with chronic hepatitis B. METHODS: Forty-four patients of chronic hepatitis B were divided into two groups, the treated group was treated with oxymatrine 0.4 g/d by intramuscular injection for 3 months, the control group was treated with some liver protecting agents to estimate the therapeutic effect. The serum level of HBV-DNA was determined by quantitative polymerase chain reaction (PCR) before and after treatment. RESULTS: The seroconversion rate of HBV-DNA and HBeAg in the treated group was 43.47% and 43.47% respectively, which was obviously better than those in the control group respectively (P < 0.05), the quantity of HBV-DNA decreased after treatment from 10(6.83 +/- 1.27) copy/ml to 10(3.35 +/- 3.08) copy/ml. Among them, in patient with HBeAg negative conversion, the pretreatment quantity of HBV-DNA was 10(6.30 +/- 1.42) copy/ml, while in those with no HBeAg negative conversion, it was 10(7.23 +/- 1.23) copy/ml, the difference was significant. CONCLUSION: Oxymatrine is effective in treating chronic hepatitis B. The therapeutic effect is better for patients with lower quantity of serum HBV-DNA.
