干扰素治疗对慢性乙型肝炎患者外周血Tc和Ts细胞的影响

目的 探讨干扰素治疗慢性乙型肝炎患者外周血Tc和Ts细胞状态的影响。并分析干扰素疗效与Tc和Ts细胞变化的关系。方法 用双重染色免疫细胞学技术检测32例干扰素治疗慢性乙型肝炎患者外周血Tc和Ts细胞。结果 有21例患者达到完全或部分应答标准。其中9例为完全应答。12例为部分应答。11例无应答；干扰素治疗结束时产生完全或部分应答组，Tc细胞水平较正常对照组均显著增高，Ts细胞水平均显著低于正常对照组；完全应答与部分应答组之间Tc和Ts细胞间的差异无显著性；无应答组Tc与完全或部分应答组相比，差异无显著性，而Ts细胞均显著高于后两组。结论 慢性乙型肝炎患者干扰素治疗可以导致患者体内Tc和Ts细胞水平发生变化。其中尤以Ts细胞的变化更为明显。Ts水平的改变可能与干扰素抗病毒疗效的关系更为密切。

Influence of interferon α on the variation of Tc and Ts cells in the peripheral blood of patients with chronic hepatitis B

OBJECTIVE: To investigate the influence of interferon-alpha on the variation of cytotoxic T lymphocytes (Tc) and suppressor T lymphocytes (Ts) in the peripheral blood of 32 patients with chronic hepatitis B, and to analyse the relationship between the efficacy of interferon-alpha and the variation of Tc and Ts cells. METHODS: The peripheral blood Tc and Ts cells were detected by the double-staining immunocytochemistry technique. RESULTS: At the end of the treatment with interferon-alpha, there were 9 complete responders (CR), 12 partial responders (PR) and 11 non-responders (NR). Tc cells significantly increased and Ts cells markedly decreased in CR or PR group compared with the healthy control group. There was no significant difference in the level of Tc and Ts cells between CR and PR groups, and no significant difference in the level of Tc cells in NR, CR and PR groups, The Ts cells was significantly higher in NR group than in CR or PR group. CONCLUSIONS: The treatment of interferon-alpha can result in the change of Tc and Ts cells in patients with chronic hepatitis B. The variation of Ts cells may play an important role in the efficacy of interferon-alpha against hepatitis B virus.
