(一)糖尿病与免疫不全1.继发性免疫不全糖尿病(下称DM)易招致感染并对感染的防御能力减低,故常伴发感染,且易趋于重症化。另一方面,倘DM得到良好的控制,感染也易被克服。故可认为以高血糖为中心的代谢异常,会引致继发性免疫不全。其证据是:1)DM酮症酸中毒患者的多核白细胞的吞噬功能明显减退;2)凡未得到很好控制的DM, (A) diabetes and immune insufficiency 1. Secondary immune deficiency diabetes (hereinafter referred to as DM) can easily lead to infection and reduce the ability of the infection, it is often associated with infection, and tend to be critically ill.
