淋巴细胞功能测定对小儿过敏性紫癜诊断与治疗的价值初探

目的研究过敏性紫癜(HSP)患儿急性期外周血淋巴细胞功能的变化,探讨其在HSP诊断与治疗中的意义。方法采用流式细胞术(FCM)对51例HSP患儿急性期和40例健康查体儿童外周血淋巴细胞亚群CD3+、CD4+、CD8+、CD4+/CD8+、CD19+和NK细胞(CD16++CD56+)进行检测。结果与对照组儿童比较,HSP患儿急性期外周血CD4+、CD4+/CD8+及NK细胞(CD16++CD56+)数量明显减低(P0.01),CD8+和CD19+细胞比率明显增高(P0.05,P0.01)。结论 HSP患儿急性期存在免疫功能紊乱,外周血淋巴细胞功能测定对HSP患儿的早期诊断与治疗有重要意义。

Preliminary study on value of lymphocyte function detection in diagnosis and therapy of Henoch-Schonlein purpura

Objective To investigate the changes of peripheral blood lymphocyte function in the children patients with acute phase of Henoch-Schonlein purpura(HSP),and to explore its significance in the diagnosis and therapy of HSP.Methods The peripheral blood lymphocytes subsets CD3+,CD4+,CD8+,CD4+/CD8+,CD19+ and NK cells(CD16++ CD56+) were detected in 51 children patients with acute phase of HSP and 40 children undergoing physical examination by flow cytometry(FCM Results Compared with the control group,the counts of peripheral blood CD4+,CD4+/ CD8+and NK cells CD16++ CD56+) in the acute stage of the HSP group were significantly decreased(P<0.01),while the proportions of CD8+ and CD19+cells were significantly increased(P<0.05,P<0.01).Conclusion The immunity dysfunction exists in the children patients with acute phase of HSP.The peripheral blood lymphocyte function detection has an important significance for the early diagnosis and treatment of HSP.
