[摘要] 目的 探讨初诊2型糖尿病患者血清维生素D与糖尿病大血管病变的关系。 方法 选择北京市垂杨柳医院内分泌科2015年5月~2016年10月初诊2型糖尿病患者239例。根据血清25(OH)D ≥ 30 ng/mL分为正常组、20~<30 ng/mL为不足组、10~<20 ng/mL为缺乏组、<10 ng/mL为严重缺乏组,观察血清25(OH)D与临床指标、糖尿病大血管病变之间的关系。 结果 初诊2型糖尿病患者血清维生素D缺乏的患病率是56.9%。各组年龄、25(OH)D、糖化血红蛋白(HbA1c)、三酰甘油(TG)、糖尿病大血管病变情况比较,差异有统计学意义(P < 0.05)。Logistic回归分析结果显示,血清25(OH)D是糖尿病大血管病变的保护因素,男性比女性更易患大血管病变,年龄、体重指数是糖尿病大血管病变的危险因素。 结论 年龄、HbA1c、TG与血清25(OH)D缺乏相关;年龄、男性、体重指数、血清25(OH)D缺乏是初诊2型糖尿病患者大血管病变的独立危险因素。

[Abstract] Objective To observe relation between vitamin D and macrovascular disease in the newly-diagnosed type 2 diabetes mellitus (T2DM) patients. Methods 239 patients with the newly-diagnosed T2DM in Department of Endocrinology, Beijing Chuiyangliu Hospital from May 2015 to October 2016 were selected. According to serum 25(OH)D level, these patients were divided into four groups: normal group (≥30 ng/mL), insufficiency group (20~<30 ng/mL), deficiency group (10~<20 ng/mL) and severe deficiency group (<10 ng/mL). Clinical characteristics and color artery ultrasound of lower extremity, carotid were measured. The relationship between serum 25(OH)D and clinical indexes, diabetic macrovascular disease were observed. Results The incidence of serum 25(OH)D deficiency was 56.9% in the newly-diagnosed T2DM group. The age, 25(OH)D, glycosylated hemoglobin (HbA1c), three acyl glycerol (TG), diabetic macrovascular complication in these groups were compared, with statistical differences (P < 0.05). Logistic regression analysis showed that serum 25(OH)D was protective factor; men were more likely than women to develop macrovascular disease; age and BMI were high risk factor of diabetic macrovascular disease (P < 0.05). Conclusion There are relation between age, HbA1c,TG and deficiency of serum 25(OH)D. Age, male, BMI and deficiency of serum 25(OH)D are important risk factors for diabetic macrovascular disease in the newly-diagnosed T2DM patients.

維生素D是一种脂溶性类固醇激素,它经肝肾羟化为有活性的1,25(OH)2D3在人体内起作用。因为25(OH)D半衰期长,是维生素D在血液循环中的主要形式,故临床上一般通过检测25(OH)D水平来了解维生素D的营养状况[1]。维生素D缺乏较为常见,目前已经成为全球性的公共健康问题[1-2]。国内外研究发现,2型糖尿病患者中维生素D缺乏可达60%~90%[2-4]。维生素D可以促进胰岛素的合成、分泌,改善胰岛素抵抗[2,5];流行病学显示,维生素D缺乏是心血管疾病的危险因素之一[6]。本研究旨在进行维生素D与糖尿病大血管病变的关系研究,对于早期诊断、预防糖尿病大血管病变的发生及发展有积极意义。
