将B型肝炎病毒(HBV)DNA转染的肝癌细胞与免疫抑制剂泼尼松龙、硫唑嘌呤和环孢素A(CsA)以及抗病毒药更昔洛韦和膦甲酸孵育,以研究这些化合物对HBV复制的影响。泼尼松龙和硫唑嘌呤使细胞内病毒DNA和RNA水平分别增加约2倍和4倍。CsA治疗并没有改变病毒RNA或DNA的水平。所有三种免疫抑制剂的组合使细胞内病毒DNA的水平增加了八倍,表明了累加效应。在存在膦甲酸的情况下孵育细胞降低了单链和松弛环状病毒DNA的水平,并且在存在更昔洛韦的情况下降低了松弛环状病毒DNA的水平,从其已知的作用机制可以预测效果。更昔洛韦-膦甲酸治疗可显著抑制免疫抑制剂联合诱导的病毒复制刺激作用。这些观察结果可能对肝移植术后复发性HBV感染的管理有意义。(Hepatology 1995 22:36-43.)
Hepatitis B virus (HBV) DNA‐transfected hepatoma cells were incubated with the immunosuppressive agents prednisolone, azathioprine, and cyclosporin A (CsA) and the antiviral agents ganciclovir and foscarnet to investigate the effects of these compounds on HBV replication. Prednisolone and azathioprine increased in‐tracellular viral DNA and RNA levels approximately twofold and fourfold, respectively. Treatment with CsA did not alter the levels of viral RNA or DNA. A combination of all three immunosuppressive agents increased the level of intracellular viral DNA eightfold, indicating an additive effect. Incubation of the cells in the presence of foscarnet decreased levels of both single‐stranded and relaxed circular viral DNA, and in the presence of ganciclovir decreased the levels of relaxed circular viral DNA, predictable effects from their known mechanism of action. The stimulatory effect on viral replication induced by the combination of immunosuppressive agents was substantially inhibited by ganciclovir‐foscarnet treatment. These observations could have implications for the management of recurrent HBV infection after liver transplantation. (Hepatology 1995 22:36–43.)
