在一个大型糖尿病队列中确定甘油三酯水平与下肢截肢(莱亚)风险之间的关系。这是一项为期10年的调查随访研究(从1995年至2006年)的28,701名糖尿病患者与基线甘油三酯测量。所有患者都是Kaiser Permanente医疗保健计划的完全保险成员,并在基线时对调查作出回应,其中包括种族,社会经济地位,教育,行为因素和确定糖尿病类型所需的信息。使用考克斯比例风险模型评价甘油三酯与非创伤性莱亚事件发生时间之间的关系,非创伤性LEA事件定义为主要住院出院或手术。在这个大型糖尿病队列中,甘油三酯水平是非创伤性LEA的独立、逐步风险因素:甘油三酯150-199 mg/dL,风险比(HR)1.10(95% CI 0.92-1.32); 200-499 mg/dL,1.27(1.10-1.47); >500 mg/dL,1.65(1.30-2.10)(参考值<150 mg/dL)。即使在控制了已知的社会经济、健康行为和临床因素后,高血糖仍是糖尿病患者发生莱亚的重要危险因素。这种以前未被认识到的临床风险需要进一步研究,以确定甘油三酯治疗是否可以降低截肢风险。
To determine the association between triglyceride levels and lower-extremity amputation (LEA) risk in a large diabetic cohort. This is a 10-year survey follow-up study (from 1995–2006) of 28,701 diabetic patients with a baseline triglyceride measure. All patients were fully insured members of the Kaiser Permanente Medical Care Program and responded to a survey at baseline that included information on ethnicity, socioeconomic status, education, behavioral factors, and information required to determine type of diabetes. The relationship between triglycerides and time to incident nontraumatic LEA, defined by primary hospitalization discharge or procedures, was evaluated using Cox proportional hazards models. Triglyceride level was an independent, stepwise risk factor for nontraumatic LEAs within this large diabetic cohort: triglycerides 150–199 mg/dL, hazard ratio (HR) 1.10 (95% CI 0.92–1.32); 200–499 mg/dL, 1.27 (1.10–1.47); >500 mg/dL, 1.65 (1.30–2.10) (reference <150 mg/dL). Hypertriglyceridemia is a significant risk factor for LEA in diabetic patients even after controlling for known socioeconomic, health behavioral, and clinical factors. This previously unrecognized clinical risk needs to be further investigated to determine if treatment of triglycerides can reduce amputation risk.
