To investigated the association between interleukin-10(IL-10)-1082/-819/-592 promoter polymorphism, plasma IL-10 levels and risk of vocal leukoplakia.
A case-control study of 61 patients with vocal cords leukoplakia and 119 healthy subjects were performed. Genotypes for the IL-10 gene (IL-10 -1082 G/A, -819 C/T and -592 C/A) were determined using pyrosequencing and plasma IL-10 levels were analyzed by ELISA.
Smoking and alcohol consumption increased the risk of vocal leukoplakia (OR = 4.73, 95%CI:2.4-9.1;OR = 5.70, 95%CI:2.9-11.2, P < 0.01) . Patients with vocal cord leukoplakia had significantly higher frequencies of AC at -592 and -819 (OR = 1.93, 95%CI:0.97-3.81, P = 0.05) and AG at -1082(OR = 2.14, 95%CI:0.87-5.27, P = 0.092) than control. Vocal leukoplakia patients had higher concentration of plasma IL-10 (21.6 ± 0.5) pg/ml (X(-) ± s) than controls (19.0 ± 1.1)pg/ml(t = 2.08, P = 0.043) and the haplotype containing the G allele was associated with higher plasma IL-10 concentrations (24.3 ± 5.7) pg/ml compared with the ATA haplotype(19.9 ± 4.7) pg/ml (t = -2.64, P = 0.008).
IL-10-1082/-819/-592 promoter polymorphism and high concentration of plasma IL-10 are associated with vocal cord leukoplakia, and the concentration of plasma IL-10 is associated with the genotypes of IL-10 promoter polymorphism.
研究白细胞介素-10（IL-10）-1082/-819/-592启动子多态性、血浆IL-10水平与声带白斑发病风险之间的关联。
对61例声带白斑患者和119例健康受试者进行病例对照研究。采用焦磷酸测序法测定IL-10基因（IL-10 -1082 G/A、-819 C/T和-592 C/A）的基因型，并用酶联免疫吸附测定法分析血浆IL-10水平。
吸烟和饮酒会增加声带白斑的发病风险（比值比=4.73，95%置信区间：2.4-9.1；比值比=5.70，95%置信区间：2.9-11.2，P<0.01）。声带白斑患者中，-592和-819位点AC基因型（比值比=1.93，95%置信区间：0.97-3.81，P=0.05）以及-1082位点AG基因型（比值比=2.14，95%置信区间：0.87-5.27，P=0.092）的频率显著高于对照组。声带白斑患者的血浆IL-10浓度（21.6±0.5）pg/ml（均数±标准差）高于对照组（19.0±1.1）pg/ml（t=2.08，P=0.043），并且含有G等位基因的单倍型与较高的血浆IL-10浓度（24.3±5.7）pg/ml相关，而ATA单倍型为（19.9±4.7）pg/ml（t=-2.64，P=0.008）。
IL-10-1082/-819/-592启动子多态性及血浆IL-10高浓度与声带白斑有关，且血浆IL-10浓度与IL-10启动子多态性的基因型有关。
