重症药疹主要包括Stevens-Johnson 综合征(Stevens-Johnson syndrome ,SJS )、大疱性表皮松解坏死型即药物引起的中毒性表皮坏死松解症(toxic

epidermal necrolysis ,TEN )、药物超敏反应综合征(drug-induced hypersensitivity syndrome ,DIHS )等,

主要是由免疫系统参与的药物不良反应,而淋巴细胞是免疫反应中的主要效应细胞。本研究采用流式细胞术对21例重症药疹患者进行外周血淋巴细胞亚群表达测定,以了解不同类型重症药疹患者免疫

[摘要]目的:检测不同类型重症药疹患者外周血淋巴细胞亚群并研究其临床意义。方法:采用免疫荧光标记流式细胞术检

测21例重症药疹患者外周血淋巴细胞的表型。结果:药物超敏反应综合征(drug-induced hypersensitivity syndrome ,DIHS )患者治疗前CD3+、CD3+CD4+淋巴细胞较正常值显著增加,并且DIHS 患者治疗前CD3+CD4+淋巴细胞显著高于Stevens-Johnson 综合征(Stevens-Johnson syndrome ,SJS )和中毒性表皮坏死松解症(toxic epidermal necrolysis ,TEN )患者;在SJS 和TEN 患者中,随着外周血CD3+CD4+、CD3+CD8+淋巴细胞数目的增加,激素最大控制用量逐渐减少,随着外周血CD3-CD16+CD56+淋巴细胞数目的增加,激素最大控制用量逐渐增加。结论:不同类型的重症药疹外周血淋巴细胞亚群不同,外周血不同类型淋巴细胞亚群对激素最大控制用量的影响不同。[关键词]

[Abstract ]

Objective :To detect lymphocyte subsets in the peripheral blood of patients with different types of severe drug eruption

and study its clinical significance.Methods :Immunofluorescence flow cytometry was performed to analyze the phenotypes of peripheral blood cells in 21patients with severe drug eruption.Results :CD3+,CD3+CD4+lymphocytes of the peripheral blood in drug-induced hypersensitivity syndrome (DIHS )patients was significantly increased in comparison with the normal value ,and CD3+CD4+lymphocytes of the peripheral blood cells in DIHS patients was significantly higher than that in Stevens-Johnson Syndrome (SJS )patients and toxic epidermal necrolysis (TEN )patients.With the increase in the number of CD3+CD4+and CD3+CD8+lymphocytes in the peripheral blood cells ,the maximum dosage of corticosteroids progressively decreased in SJS and TEN patients.With the increase in the number of CD3-CD16+CD56+lymphocytes of the peripheral blood cells ,the maximum dosage of corticosteroids progressively increased in SJS and TEN patients.Conclusion :Different types of severe drug eruption have different lymphocyte subsets in the peripheral blood ,which have different effects on the maximum dosage of corticosteroids.
