拉米夫定耐药后的抗乙型肝炎病毒治疗

目的探讨拉米夫定耐药后慢性乙型肝炎患者采用α2b干扰素或α2b干扰素加α1胸腺肽进行后续抗病毒的疗效。方法共66例拉米夫定耐药患者,分治疗组A、治疗组B和对照组。治疗组A26例,单用α2b干扰素治疗1个月后停用拉米夫定,然后继续单用α2b干扰素治疗5个月;治疗组B10例,α2b干扰素和α1胸腺肽联合治疗1个月后停用拉米夫定,然后继续两药联合治疗5个月;对照组30例,直接停用拉米夫定,不用其他任何抗病毒药。定期进行血清肝功和病毒学指标检测。结果治疗组A和治疗组B的HBVDNA阴转率和HBeAg/HBeAb转换率均明显高于对照组。结论慢性乙型肝炎患者拉米夫定耐药后采用α2b干扰素或α2b干扰素加α1胸腺肽进行后续抗病毒治疗可能是有益的。

Antiviral therapy of chronic hepatitis B patients resistant to lamivudine

BACKGROUND: To evaluate the efficacy of alpha-2b interferon alone or combined with alpha1-thymosin in treatment of patients with chronic hepatitis B (CHB) resistant to lamivudine. METHODS: Sixty six patients with CHB resistant to lamivudine were enrolled and randomized into treatment group A, treatment group B and control group. In the treatment group A 26 cases, after giving interferon-alpha alone for 1 month, lamivudine was withdrawn and continuously treated with interferon-alpha for 5 months. In the treatment group B 10 cases, after treatment with interferon-alpha and thymosin-alpha1 for 1 month, lamivudine was withdrawn and continuously treated with interferon-alpha and thymosin-alpha1 for 5 months. In control group (30 cases), after lamivudine was directly withdrawn, no anti-virus drug was given. Hepatic function tests and serum virological index were detected at regular intervals in all patients. RESULTS: Normalization rate of hepatic function, HBV DNA seroconversion rate and HBeAg/HBeAb seroconversion rate in two treatment groups were significantly higher than those in control group. CONCLUSION: The study suggested that interferon-alpha alone or combined with thymosin-alpha1 in treatment of patients with chronic hepatitis B resistant to lamivudine showed a beneficial effect.
