摘要: 为探讨老年严重急性呼吸综合征(SARS)患者细胞免疫功能的变化,为临床提供理论依据,对211例SARS患者按不同年龄、疾病严重程度以及激素使用情况分组。采用流式细胞技术测定患者不同病程的外周血T淋巴细胞亚群的变化。结果所有患者发病后均出现T淋巴细胞的明显下降,低谷出现于发病后22.83d。老年SARS患者疾病极期T细胞各亚群绝对数均低于中青年患者,重症患者低于轻症患者(P<0.01)。激素使用与否以及剂量大小对T细胞影响不大。提示SARS患者发病初期细胞免疫功能受到明显损害,老年、重症SARS患者的损害更为显著,外周血CD3+、CD4+、CD8+细胞下降的程度可作为病情轻重及预后判断的指标之一。

Abstract: The objective was to investigate the changes of subgroups of peripheral blood Tlymphocytes in elderly patients with severe acute respiratory syndrome(SARS).Methods Subgroups of peripheral blood Tlymphocytes in211patients,including 40 elderly patients with SARS were detected by flow cytometer.Results The number of CD3,CD4,and CD8 lymphocytes all significantly decreased in acute phase of patients with SARS.The counts of CD3,CD4 ,and CD8 lymphocytes decreased more apparently in elderly patients with SARS.Conclusion The cellular immunity is damaged in SARS patients,more apparently in elderly patients with SARS.

Key words: elderly patients, severe acute respiratory syndrom(SARS), T lymphocytes
