昆明医科大学第一附属医院皮肤科、中科院昆明动物研究所等研究团队历时3年,从全国30余家医院收集到近8000例我国汉族重度痤疮患者及对照样本资源,率先运用全基因组关联研究方法进行基因筛查与分析,发现两个遗传易感基因:SELL和DDB2,分别与雄激素代谢通路、炎症过程及疤痕形成有关,它们的异常表现很可能导致重度痤疮的发生。

痤疮在临床上主要分为轻度和重度两种。论文通讯作者、昆明医科大学第一附属医院皮肤科主任何黎教授说,两种类型痤疮对患者的困扰不同:轻度主要局限于面部,皮损少、炎症轻;重度则表现为颜面、前胸及后背部的囊肿、结节,易形成瘢痕,损害重、病程长、遗留的瘢痕临床疗效不佳。另外,他们在近10年的研究中发现,痤疮遗传度高达88%,重度痤疮具有明显的家族遗传性,呈现出多基因遗传病的特点,而轻度主要与环境因素有关。“为此,我们将研究重点放在重度痤疮的遗传易感基因上。”

该研究无疑对重度痤疮的临床治疗指出了方向,如平衡患者的雄激素水平,保持皮肤水油平衡,并进行抗炎治疗。何黎认为,两个易感基因的发现为重度痤疮的早期诊断、早期干预提供理论依据,也为医用护肤品及相关药物的研发提供了靶点。
