摘要 尿毒症毒素是慢性肾脏病(chronic kidney disease,CKD)患者体内蓄积的具有明显毒性作用的物质。硫酸吲哚酚(indoxyl sulfate,IS)是肠道细菌分解色氨酸产生的蛋白结合型的小分子物质,正常生理情况下,通过肾脏排出。CKD患者的肾脏排泄功能明显下降,对IS的清除能力也随之降低,导致IS在体内蓄积,引起多器官系统发生功能障碍。大量研究证实,IS可直接诱导肾小管细胞凋亡,促进心血管事件发生,还可以减少破骨细胞分化并促进成骨细胞凋亡,加重肾性骨病。IS作为肠道来源毒素,其产生不可避免,因此研究IS的毒性作用对CKD患者的预后有重要帮助。本文就近年来关于IS毒性作用的认识研究进展做一综述。
