白癜风患者血清细胞因子水平变化

为了研究白癜风的细胞免疫变化，我们应用ＥＬＪＳＡ技术检测了４１例非节段型白癜风病人及３０例正常人血清白介素２（ＩＬ－２）和肿瘤坏死因子（ＴＮＦα）的水平，同时了血清可溶性白介系２受体（ｓＩＬ－２Ｒ）的水平。结果显示白癜风病人的血清ＩＬ－２水平明显下降，ｓＩＬ－２Ｒ和ＴＮＦα水平明增高。研究表明非节段型白癜风病人存在细胞免疫缺陷，提示免疫机制在白癜风发病中的可能直作用。     

色素障碍性皮肤病

卡介菌多糖核酸对尖锐湿疣患者外周血淋巴细胞mIL－2R表达及sIL－2R水平的影响

采用ＩＩＦ和ＥＬＩＳＡ法分别检测了２２例尖锐湿疣（ＣＡ）患者和１６例正常对照者外周血淋巴细胞（ＰＢＬ）上膜白细胞介素２受体（ｍＩＬ－２Ｒ）表达水平及其培养上清中可溶性白细胞介素２受体（ｓＩＬ－２Ｒ）的含量，同时观察了卡介菌多糖核酸（ＢＣＧ－ＰＳＮ）在体外对这两项指标的影响。结果发现，患者ＰＢＬ上ｍＩＬ－２Ｒ表达下降，而培养上清中ｓＩＬ－２Ｒ含量明显增高；一定浓度的ＢＣＧ－ＰＳＮ能在体外使患者淋巴细胞ｍＩＬ－２Ｒ表达增强，以及降低培养上清中ｓＩＬ－２Ｒ的含量。这表明ＣＡ患者存在细胞免疫缺陷，ＢＣＧ－ＰＳＮ能在体外调节患者细胞免疫功能。

Serum concentrations of interleukin-2 soluble receptor (IL-2 sR) in patients with vitiligo: relationship with type and extent of the disease

Vitiligo is a disorder of melanin pigmentation, affecting 1-2% of general population. The etiopathogenesis of the disease is not clear, but probably includes the interaction among nervous system, cytotoxic factors, and immune mechanisms. The aim of the study was to evaluate serum concentrations of interleukin-2 soluble receptor (IL-2 sR) in patients with vitiligo and assess a possible association between IL-2 sR and clinical type, extent, and duration of the disease. The study included 51 patients with vitiligo aged 7-70 years and 29 healthy controls aged 10-60 years. Serum concentrations of IL-2 sR were determined by ELISA method. The serum concentration of IL-2 sR in patients with vitiligo was lower than that in the control group (1,164.2+/- 357.2 vs. 1,301.6+/-404.1 pg/mL, respectively). Significantly decreased serum IL-2 sR concentrations were noticed in patients with non-dermatomal type A vitiligo (1,137.5+/-356.7 pg/mL), especially those suffering from type A1 (active lesions) of the disease (959.4+/-251.7 pg/mL), compared with both healthy controls and patients with type B (dermatomal) vitiligo (1,105.2+/-346.5 pg/mL). In patients with more extensive vitiliginous changes of the skin, IL-2 sR serum concentrations were significantly lower. Moreover, patients with type A1 vitiligo had significantly decreased serum IL-2 sR concentrations compared with type A2 (non-active lesions) patients. There was no difference in serum IL-2 sR concentrations between patients with dermatomal distribution of vitiligo and control group. Serum IL-2 sR concentrations in patients with vitiligo were decreased and depended on the activity and intensity of the disease process.     

白癜风患者血清白细胞介素33及其可溶性受体ST2水平检测及意义

 目的:探讨白癜风患者血清白细胞介素33（IL-33）及其可溶性受体ST2（sST2）表达水平的变化及其临床意义。方法：采用酶联免疫吸附试验对62例白癜风患者和30例健康对照组血清IL-33和sST2表达水平进行检测,并分析IL-33和sST2在白癜风患者不同分期、面积、病程等分组中的表达差异。结果：白癜风患者外周血中IL-33和sST2水平在进展期及稳定期均明显高于正常对照组（IL-33：t值分别为4.67、2.34,P值分别为0.004、0.031;sST2：t值分别为3.59、2.09,P值分别为0.027、0.045）。白癜风患者自身抗体异常组sST2水平明显高于无自身抗体异常组,差异有统计学意义（t=2.46,P=0.015）;不同分期、性别、白斑面积、家族史、精神应激、微量元素临床亚组间IL-33和 sST2水平差异均无统计学意义（P值均>0.05）。外周血IL-33和 sST2水平与年龄及病程均无明显相关性（P值均>0.05）。结论：IL-33及sST2可能与白癜风的发病密切相关。IL-33水平升高可能主要发生在白癜风起始阶段,与疾病活动度及严重程度无明显相关。sST2水平的升高可能是IL-33介导的炎症反应和免疫应答的负反馈调节机制。

Abstract：

Objective To measure the serum levels of 15 neuroendocrine and immune factors, including angiotensin-Ⅱ (ANG-Ⅱ), endorphin-β (EP-β), interferon-γ (IFN-γ), soluble intercellular adhesion molecule-1 (sICAM-1), 5-thrombotonin (5-HT), interleukin-10 (IL-10), IgM, tumor necrosis-α (TNF-α), IL-8, IL-6, IgG,IL-2, norepinephrine, cortisol and adrenaline in patients with vitiligo, and to analyze their association with the development of vitiligo according to traditional Uyghur medicine theory. Methods Enzyme-linked immunosorbent assay (ELISA) was conducted to measure the serum levels of the above 15 neuroendocrine and immune factors in 175 patients with vitiligo and 60 normal human controls. Results There was a significant increase in the serum levels of ANG-Ⅱ , EP-β, IFN-γ, sICAM-1, 5-HT, IL-10, IgG, norepinephrine, cortisol and adrenaline, together with a decrease in those of TNF-a, IL-8, IL-2 and IL-6 in patients with vitiligo compared with the controls (all P < 0.01). No statistical difference was observed for the serum level of IgM between the patients and controls (P > 0.05). Increased serum levels of ANG-Ⅱ, 5-HT, IL-8 and cortisol were noted in patients with stable vitiligo in comparison with those with progressive vitiligo (all P < 0.01), while the levels of the other factors were similar between the stable and progressive vitiligo patients. Conclusions The development of vitilito is a comprehensive process with the involvement of various neuroendocrine and immune factors,and whether the conclusion agrees with the traditional Uyghur medicine theory that imbalanced "kuwiti tabiiy" ["Nature power" (of human body)] induces vitiligo derserves further studies.     

Levels of soluble interleukin-2 receptor in the sera and skin tissue fluids of patients with vitiligo.

In order to study the possible role of soluble interleukin-2 receptor (sIL-2R) in the pathogenesis of vitiligo, we measured the levels of sIL-2R in the sera and the tissue fluids from skin lesions and uninvolved skin from 41 patients with vitiligo, using the method of sandwich ELISA with monoclonal and polyclonal antibodies. The results showed that the overall level of serum sIL-2R from patients with vitiligo was significantly higher than that from normal control group (P<0.01). The serum level of sIL-2R in both generalized and focal types was significantly higher than that in normal control group (P<0.01), but there was no significant difference between the segmental type and normal control group (P>0.05). The level of serum sIL-2R from patients with vitiligo in progressive stage was significantly higher than that in stable stage (P<0.01). The level of sIL-2R in the tissue fluid from the skin lesion of the patient was significantly higher than uninvolved skin of the same patient (P<0.05). The above data indicate that there is an association between the expression of sIL-2R and the pathogenesis of vitiligo. The level of serum sIL-2R in vitiligo is related to the activity of the disease, therefore the measurement of it may be significant in estimating the severity and the prognosis of the disease.
