目的了解掌跖脓疱病患者血清肿瘤坏死因子α(TNF-α)、白细胞介素(IL)17、IL-22和IL-17F表达水平,探讨它们和疾病活动的相关性.方法掌跖脓疱病患者30例和健康人对照20例.采取掌跖脓疱病患者活动期、静止期及对照组外周静脉血,采用ELISA法检测外周血中TNF-α、IL-17、IL-22及IL-17F含量.患者组活动期与静止期细胞因子水平的差异采用配对秩和检验比较,组间差异采用Mann-Whitney U检验比较.结果掌跖脓疱病患者活动期外周血TNF-α、IL-17、IL-22表达水平[中位数(范围)为186.35(113.48 ～ 412.69) ng/L、420.45(278.55 ～ 748.73) ng/L、106.48(69.13 ～ 251.86) ng/L)]分别高于静止期[42.52(18.83 ～ 95.37) ng/L、48.11(36.43～80.04) ng/L、20.32(10.55 ～48.75) ng/L),T值分别为1.5、2.0、3.0,均P＜ 0.05]和对照组[24.30(12.09 ～ 61.56) ng/L、10.49(6.24～24.44) ng/L、2.58(1.41～5.78) ng/L,u值分别为4.17、3.84、4.69,均P＜0.05];静止期也显著高于对照组,差异有统计学意义(u值分别为2.71、3.53、2.18,均P＜0.05).但各组间IL-17F差异无统计学意义(均P＞0.05).结论掌跖脓疱病患者外周血TNF-α、IL-17、IL-22表达水平与疾病活动相关,提示TNF-α、IL-17和IL-22可能参与掌跖脓疱病的发病过程.

Objective To determine the serum levels of tumor necrosis factor (TNF)-α,interleukin (IL)-17,IL-22 and IL-17F in patients with palmoplantar pustulosis (PP),and to estimate their relationship with disease activity in PP.Methods Venous blood samples were collected from 30 patients with PP at both active stage and stationary stage and from 20 healthy human controls.Enzyme-linked immunosorbent assay (ELISA) was conducted to determine the serum levels of TNF-α,IL-17,IL-22 and IL-17F.The paired Wilcoxon signed rank test was carried out to compare the serum levels of cytokines between patients at active stage and at stationary stage,and the Mann-Whitney U test to compare those among different groups.Results The median serum levels of TNF-α,IL-17 and IL-22 in patients with PP at active stage were 186.35 (range,113.48-412.69) ng/L,420.45 (range,278.55-748.73) ng/L and 106.48 (range,69.13-251.86) ng/L respectively,significantly higher than those at stationary stage (42.52(18.83-95.37) ng/L,48.11 (36.43-80.04) ng/L,20.32 (10.55-48.75) ng/L,respectively,all P ＜ 0.05) and those in the controls (24.30 (12.0-61.56) ng/L,10.49 (6.24-24.44) ng/L,2.58 (1.41-5.78) ng/L,respectively,all P ＜ 0.05).Moreover,the patients at stationary stage showed a significant elevation in serum levels of TNF-α,IL-17 and IL-22 compared with the controls (u =2.71,3.53,2.18,respectively,all P ＜ 0.05).No statistical difference was noted in the serum level of IL-17F among the patients at different stages and controls (P ＞ 0.05).Conclusion The circulating levels of TNF-α,IL-17 and IL-22 were associated with disease activity in PP,hinting that they may be involved in the development of PP.
