Diabetes Care:低水平高密度脂蛋白胆固醇升高糖尿病肾病风险

来源:生物谷 2012-08-24 09:12

2012年8月24日 讯 /生物谷BIOON/ --高密度脂蛋白胆固醇(HDL-C)是糖尿病肾病发生的一个独立危险因素,但并不是2型糖尿病患者视网膜病变发生的诱发危险因子,相关研究论文发表在8月13日的Diabetes Care杂志上。

悉尼心脏研究所内外全科医学士Jamie Morton和同事们追访研究11140例参试人员,参与者患有2型糖尿病并至少有一个额外的血管危险因素。研究的目的是评估HDL-C和微血管病变(复合肾脏和视网膜的事件)之间的关联。

超过平均五年的随访研究,研究人员发现28%的患者会经历肾病事件,6%的患者会经历视网膜病变事件。相对于那些最高水平的HDL-C患者来说,最低水平的HDL-C患者中并发肾病的风险有19%(肾病同时出现视网膜微血管事件的风险足足高出了17%)。但HDL-C的水平和视网膜事件之间没有任何关联(P = 0.9)。

研究作者在论文中写道,总之,对人口众多的2型糖尿病患者来说,低水平的HDL-C被证明是糖尿病肾病的发生和发展的一个独立危险因素,因此测量此脂质馏分对于疾病的筛查和治疗可能是有用的。(生物谷:Bioon.com)

OBJECTIVE Although low HDL cholesterol (HDL-C) is an established risk factor for atherosclerosis, data on HDL-C and the risk of microvascular disease are limited. We tested the association between HDL-C and microvascular disease in a cohort of patients with type 2 diabetes.

RESEARCH DESIGN AND METHODS A total of 11,140 patients with type 2 diabetes and at least one additional vascular risk factor were followed a median of 5 years. Cox proportional hazards models were used to assess the association between baseline HDL-C and the development of new or worsening microvascular disease, defined prospectively as a composite of renal and retinal events.

RESULTS The mean baseline HDL-C level was 1.3 mmol/L (SD 0.45 mmol/L [range 0.1–4.0]). During follow-up, 32% of patients developed new or worsening microvascular disease, with 28% experiencing a renal event and 6% a retinal event. Compared with patients in the highest third, those in the lowest third had a 17% higher risk of microvascular disease (adjusted hazard ratio 1.17 [95% CI 1.06–1.28], P = 0.001) after adjustment for potential confounders and regression dilution. This was driven by a 19% higher risk of renal events (1.19 [1.08–1.32], P = 0.0005). There was no association between thirds of HDL-C and retinal events (1.01 [0.82–1.25], P = 0.9).

CONCLUSIONS In patients with type 2 diabetes, HDL-C level is an independent risk factor for the development of microvascular disease affecting the kidney but not the retina.
