摘 要 目的:評價補硒干預對尋常型銀屑病治療的療效與安全性。方法:對補硒干預治療尋常型銀屑病的臨床隨機、對照試驗進行質(zhì)量評價和數(shù)據(jù)分析,采用RevMan 5.0軟件進行meta分析,評價患者的血硒水平、治療有效率和不良事件發(fā)生率。共納入1 285例尋常型銀屑病患者,其中補硒干預組665例患者接受免疫抑制劑治療聯(lián)合補硒干預,對照組620例患者僅接受免疫抑制劑治療。結(jié)果:補硒干預能提高尋常型銀屑病治療的療效[比值比(odds ratio, OR)=2.68, 95% CI: 2.09, 3.44; P<0.01]、提高患者的血硒水平(標準化均數(shù)差=10.87, 95% CI: 9.25, 12.49; P<0.01),且不會引起明顯的不良事件發(fā)生(OR=1.31, 95% CI: 0.68, 2.53; P<0.01)。結(jié)論:補硒干預能提高尋常型銀屑病治療的療效,安全性良好。

ABSTRACT Objective: To evaluate the efficacy and safety of selenium supplementation in the treatment of psoriasis vulgaris. Methods: Its quality was evaluated and the related data were analyzed by a clinical randomized controlled trial (RCT), and meta analysis was carried out by RevMan 5 software. The blood selenium levels, efficiency and the incidence of adverse events were also evaluated. One thousand and two hundreds and eighty-five patients with psoriasis vulgaris were divided an intervention group with 665 cases treated with immunosuppressive therapy plus selenium supplementation and a control group with 620 cases treated with only immunosuppressive therapy. Results: The intervention of selenium supplementation could improve the efficacy [odds ratio (OR)=2.68, 95% CI: 2.09, 3.44; P<0.01] and increase the blood selenium level (standardized mean difference=10.87, 95% CI: 9.25, 12.49; P<0.01), which could not result in the occurrence of obvious adverse events(OR=1.31, 95% CI: 0.68, 2.53; P<0.01). Conclusion: Selenium supplementation can improve the curative effect of psoriasis vulgaris with good safety.

銀屑病是一種常見且易反復的慢性炎癥性皮膚病,流行病學研究顯示其人口患病率為1% ~ 3%[1]。對中重度銀屑病,常用的治療藥物或方法有甲氨蝶呤、環(huán)孢素A、維A酸類似物、糖皮質(zhì)激素類藥物和光療等[2]。目前公認銀屑病是由輔助性T細胞(helper T cells, Th)失衡并有多種細胞因子介導的自身免疫紊亂性疾病[3]。硒是人體必需的微量元素,有關(guān)研究證實硒對人體免疫功能的影響是多方面和復雜的,硒對免疫功能如特異性免疫、非特異性免疫功能低下均有明顯的增強作用,同時對免疫功能紊亂患者也有較好的調(diào)節(jié)作用,可能是主要通過調(diào)節(jié)Th1與Th2間的平衡、抑制細胞因子產(chǎn)生而調(diào)節(jié)免疫、抑制炎癥反應的[4]。近年來,硒制劑被廣泛用于甲狀腺炎、銀屑病等自身免疫性疾病治療,但其能否提高這些疾病的治療療效卻不明晰。本研究探究補硒干預對尋常型銀屑病的療效與安全性。endprint
