结缔组织病(connective tissue disease)是一种风湿性疾病,表现为结缔组织的慢性炎症,会波及身体很多组织器官[1]

病理

结缔组织是具有细胞外基质、可以支持、连结器官,并且保护器官的组织。这类的组织主要由两种结构蛋白质分子所组成:胶原蛋白弹性蛋白。生物体内有许多不同的胶原蛋白,分布在各组织中。弹性蛋白类似弹簧,在受力时可以伸展,之后可以回到其原始的长度。弹性蛋白是连接骨头和骨头的韧带的主要成分,也是皮肤的主要成分。若患有结缔组织疾病,常见的情形是胶原蛋白及弹性蛋白因为发炎而受损。许多结缔组织疾病的特点是免疫系统的异常活动,以及结缔组织的发炎,因此也是自体免疫疾病[2]

若是容易使胶原蛋白发炎或是弱化的疾病,也会称为是胶原疾病英语collagen disease胶原血管疾病英语Collagen vascular disease常常和胶原蛋白及血管的异常有关(不过也有例外),在本质上也是自体免疫[2]

结缔组织疾病可能有遗传上的风险,或强或弱不等,也可能是因为环境因素而造成。

症状

结缔组织病可能引发肺部问题,如肺间质病变[1]肺动脉高压,后者可能进而发展成肺源性心脏病[3]
