摘要： 目的 探讨银屑病患者血清白介素（IL）36（IL-36α、IL-36β、IL-36γ）及其受体拮抗剂IL-36Ra水平与银屑病病情严重度的相关性。 方法 采用酶联免疫吸附试验（ELISA）比较45例泛发性脓疱性银屑病（GPP）患者、34例寻常性银屑病（PV）患者和37例健康对照者血清IL-36及IL-36Ra水平，并结合患者病情严重度进行相关性分析。 结果 IL-36及IL-36Ra在3组之间表达差异无统计学意义。银屑病患者按病期分组后，GPP脓疱发作期患者27例血清IL-36β、γ表达水平（中位数 ± 四分位数间距分别为12.101 ± 11.315和34.541 ± 15.580 ng/L）显著高于健康对照组（分别为5.355 ± 9.020和23.052 ± 22.410 ng/L），经非参数Mann-Whiteney检验，差异均有统计学意义（P < 0.05）。按病情严重度分组后，重度GPP患者7例血清IL-36β、γ表达水平（分别为11.218 ± 9.318和38.536 ± 17.332 ng/L）均显著高于健康对照组（P < 0.01）。GPP组、PV组及健康对照组IL-36β与γ表达水平均呈显著正相关（r值分别为0.85、0.86、0.91，均P < 0.01）；且两者均与GPP病情严重度呈低度正相关（r值分别为0.33、0.41，均P < 0.05）；IL-36β表达水平尚与PV皮损面积严重指数显著正相关（r = 0.54，P < 0.01）。 结论 GPP患者血清IL-36β、γ水平与病情严重度呈低度正相关，提示IL-36β、γ可能在GPP的发病中发挥重要作用。

Methods Venous blood samples were collected from 45 patients with generalized pustular psoriasis （GPP）, 34 patients with psoriasis vulgaris （PV）, and 37 healthy human controls. Enzyme-linked immunosorbent assay（ELISA） was performed to determine the serum levels of IL-36α, IL-36β, IL-36γ and IL-36Ra. Nonparametric Mann-Whitney test was conducted to compare the levels of IL-36 and IL-36Ra among these groups, and Spearman′s rank correlation analysis to assess the relationship between the serum levels of IL-36 and IL-36Ra and disease severity. Results No statistical difference was observed in the serum levels of IL-36 or IL-36Ra among the patients with GPP, patients with PV, and healthy human controls. The serum levels of IL-36β and IL-36γ （given as the median ± interquartile range） were significantly higher in 27 patients with GPP during episodes of pustules （（12.101 ± 11.315） ng/L and （34.541 ± 15.580） ng/L respectively） and in 7 patients with severe GPP （（11.218 ± 9.318） ng/L and （38.536 ± 17.332） ng/L respectively） than in the healthy human controls （（5.355 ± 9.020） ng/L and （23.052 ± 22.410） ng/L respectively, P < 0.05 or 0.01）. The serum level of IL-36γ was positively correlated with that of IL-36β in patients with GPP, patients with PV, and the healthy human controls （r = 0.85, 0.86, 0.91, respectively, all P < 0.01）, and both IL-36β and IL-36γ serum levels were lowly and positively correlated with the severity of GPP （r = 0.33, 0.41, respectively, both P < 0.05）. A positive correlation was also observed between the serum level of IL-36β and psoriasis area and severity index （PASI） scores in patients with PV （r = 0.54, P < 0.01）. Conclusions The serum levels of IL-36β and IL-36γ are lowly and positively correlated with disease severity in patients with GPP, suggesting that IL-36β and IL-36γ play an important role in the pathogenesis of GPP.
