【摘要】 糖尿病改变了患者对环境危害因素的易感性，主要表现在环境因素增加了糖尿病人群急性心脑血管并发症的发病率，降低了该人群的免疫力，并导致糖尿病人群的肺、肝、肾及神经等多系统损害比健康人群更严重。糖尿病对环境因素易感性改变的可能机制包括改变毒物代谢动力学规律、抑制组织代偿性修复能力、诱发氧化应激及扰乱机体炎症调节反应和凝血机制，但其确切的易感性特征及其机制有待进一步研究，为保护糖尿病人群的健康提供依据。

　　【Abstract】 People with diabetes may have an enhanced susceptibility to environmental hazards. This review comprehensively addresses the pattern of increased susceptibility of diabetes to environmental pollutants and the results showed that risk of environmental hazards in cardiovascular, pulmonary, liver, kidney and nervous systems increased in diabetic patients. Furthermore, when exposing to environmental hazards, the immune system were worse damaged in individuals with diabetes. The mechanisms of the susceptibility of people with diabetes to environmental toxicants are related to: (1) The toxicokinetics of environmental toxicants in subjects with diabetes are changed; (2) The compensatory capacity of tissue repair in subjects with diabetes was inhibited; (3) Diabetes induces the oxidative stress; (4) Inflammatory and coagulation mechanisms also involved. The specific policy is warranted for protection of diabetes from environmental and occupational hazards, based on clarification of exact altitude of altered susceptibility and potential mechanisms in diabetes.
