摘要
为了探讨淋巴细胞胞浆内IFN-γ水平在再生障碍性贫血(aplastic anemia,AA)患者治疗方案选择及预后判断中的作用及其临床意义,采用流式细胞技术动态监测免疫抑制治疗前后淋巴细胞胞浆内IFN-γ水平变化,同时记录患者血常规指标的变化及用药情况等。结果发现:在50例患者中有28例T淋巴细胞内IFN-γ水平高于正常值,占56%,24例IFN-γ水平增高患者的免疫抑制治疗有效率达85.7%,其IFN-γ水平下降与血象恢复基本呈正相关,并且明显早于血液学缓解。结论:IFN-γ水平升高的AA患者用免疫抑制剂治疗效果好,IFN-γ水平变化明显早于血常规指标的变化,这对于提示疗效及复发有重要意义。
This study was aimed to investigate the effects of the introplasmic interferon-γlevel in circulating T cell of patients with aplastic anemia （AA） and its clinical significance. The interferon-γ level before and after immuno- suppressive therapy was monitored by flow cytometry. The results indicated that the higher interferon-γ level was detected in 28 out of 50 AA patients, detected rate was 56%. The effective rate of immunosuppressive therapy for AA patients with higher interferon-γ level was up to 85.7% （24/28）. The decrease of interferon-γ level in these patients positively correlated with hemogram recovery to normal level and obviously earlier than hematologic remission. It is concluded that the immunosuppressive therapy shows better efficacy for AA patients with high interferon-γ level, moreover the change of interferon-γ level is earlier than hematologic change, that is important for predicting the therapeutic efficacy and relapse of disease.
