摘要
目的糖尿病患者骨质疏松以及骨折的风险较非糖尿病患者增加,在1型糖尿病患者中表现明显,但对于2型糖尿病患者骨折的风险和骨密度的变化存在争议。本研究探讨25(OH)VD和骨转换指标在2型糖尿病患者的变化,分析其对骨代谢的影响。方法收集2007.12至2011.10于我院就诊的437例未接受维生素D补充治疗的病程不超过5年的2型糖尿病患者(T2DM),同时收集非糖尿病的对照组(NDM)414例,测定各组患者骨生化指标,并收集临床资料以备数据分析使用。结果与非糖尿病组患者相比,2型糖尿病患者血清25(OH)VD水平明显降低(P=0.001),骨特异性碱性磷酸酶(BAP)、抗酒石酸酸性磷酸酶(TRAP)水平升高,骨转换活跃;男性、女性2型糖尿病患者血清25(OH)VD水平均较非糖尿病组降低(P均<0.001);相关分析显示,2型糖尿病患者血清25(OH)VD水平与空腹血糖呈负相关,而与糖化血红蛋白、HOMA-IR等无明显相关性。结论 2型糖尿病患者血清25(OH)VD水平明显低于非糖尿病者,且与空腹血糖呈负相关,糖化血红蛋白与25(OH)VD的相关性不如空腹血糖明显。
Objective The risk of osteoporosis and fracture in diabetic patients was higher than that in the non - diabetic patients. This was significant in type I diabetes patients. However, the risk of the fracture and variation of bone mineral density （BMD） was controversial. This paper aimed to explore the variations of 25 （OH） VD level and bone turnover biomarkers in type 2 diabetic patients and to analyze their effects on bone metabolism. Methods Totally 437 type 2 diabetic patients with less than five-year duration and without vitamin D supplement were chosen as subjects. Another 414 non-diabetic patients were chosen as controls. The bone biomarkers were measured. The clinical data were collected to analyze. Results The serum 25 （OH） VD level in diabetic patients was significantly lower than that in the non-diabetic patients （P --- 0. 001）. The serum bone-specific alkaline phosphatase （BAP） and tartaric-resistant acid phosphatase （TRAP） were significantly higher than that in the non- diabetics patients. Bone turnover in diabetic patients was active. The serum 25 （25） VD level decreased both in female and male diabetic patients （P 〈 0. 001 ）. Correlation analysis showed that the 25 （OH） VD level was negatively associated with fast blood glucose level. The 25 （OH） VD level was not associated with glycosylated hemoglobin （HbAlc） and HOMA-IR. Conclusion The serum 25-（OH） VD level in type 2 diabetic patients is significantly lower than that in non-diabetic patients. It is negatively associated with fast blood glucose level. Its correlation with glycosylated hemoglobin （HbAlc） is less obvious than with fast blood glucose.
