JCEM:血清FGF21或有助于糖尿病类型识别

2013-12-13 佚名 丁香园

成纤维细胞生长因子(FGF)21是一种对动物血糖和血脂代谢有多重有益影响的内分泌因子。为了探讨血清FGF21水平与1型糖尿病、成人迟发型自身免疫性糖尿病(LADA)以及2型糖尿病的关系,来自中国中南大学附属湘雅二院的周智广教授及其团队进行了一项研究,该研究发现2型糖尿病患者血清FGF21水平增加,而1型糖尿病和LADA患者FGF21水平降低。在自身免疫性糖尿病中,循环FGF

成纤维细胞生长因子(FGF)21是一种对动物血糖和血脂代谢有多重有益影响的内分泌因子。为了探讨血清FGF21水平与1型糖尿病、成人迟发型自身免疫性糖尿病(LADA)以及2型糖尿病的关系,来自中国中南大学附属湘雅二院的周智广教授及其团队进行了一项研究,该研究发现2型糖尿病患者血清FGF21水平增加,而1型糖尿病和LADA患者FGF21水平降低。在自身免疫性糖尿病中,循环FGF21下降与胰腺β细胞自身免疫密切相关。该研究结果发表在2012年1月的The Journal of Clinical Endocrinology & Metabolism杂志上,该杂志影响因子为6.430.该研究中,在76例1型糖尿病患者、68例LADA患者、77例2型糖尿病患者、以及年龄和性别匹配的对照组受试者中,使用ELISA测量血清FGF21水平。研究血清FGF21与自身免疫指标之间的关系。

该研究结果表明,1型糖尿病患者血清FGF21水平显著低于对照组受试者。校正体重指数后,LADA患者血清FGF21水平显著低于对照组受试者。与之相反,2型糖尿病患者血清FGF21水平显著高于对照组受试者。从1型糖尿病、LADA到2型糖尿病,FGF21水平逐步增加。此外,1型糖尿病和LADA患者FGF21水平与谷氨酸脱羧酶抗体和胰岛素瘤相关蛋白2自身抗体滴度呈负相关。

该研究发现,2型糖尿病患者血清FGF21水平增加,而1型糖尿病和LADA患者FGF21水平降低。在自身免疫性糖尿病中,循环FGF21下降与胰腺β细胞自身免疫密切相关。

研究背景:成纤维细胞生长因子21(FGF21)是内分泌型FGF亚家族中的一员,而且是一种重要的代谢调节因子。尽管FGF21对动物的血糖和血脂代谢有多重有益影响,但肥胖和糖尿病、血脂异常、糖耐量异常、非酒精性脂肪性肝病、以及冠心病患者中,循环FGF21水平升高。有人提出肥胖相关疾病中FGF21水平升高是由FGF21抵抗引起。

尽管之前多项研究报道2型糖尿病患者中FGF21水平升高,FGF21与自身免疫性糖尿病之间的关系仍不清楚。在这项研究中,探讨与年龄和性别匹配对照受试者相比,1型糖尿病、成人迟发型自身免疫性糖尿病(LADA)和2型糖尿病患者血清FGF21水平变化。此外,分析患者血清FGF21水平与自身免疫指标的关系。
