Abstract:
Objective:To investigate the relationship and clinical significance between serum 25(OH)D level and diabetic microangiopathy.Methods:The clinical data of 198 patients in Chaoyang Central Hospital with Type 2 diabetes from October 2018 to October 2019 were analyzed retrospectively.Patients were divided into simple diabetes group (50 cases) and microangiopathy group (148 cases) according to whether the patients had microvascular disease or not.The concentration of serum 25(OH)D in two groups of diabetic patients was compared and analyzed.Patients with type 2 diabetes were divided into two groups, which was 25 (OH)D <50 nmol/L Group (121 cases) and 25 (OH)D ≥50 nmol/L Group (77 cases) according to the different serum concentrations of 25 (OH)D.The incidence of MVCD was analyzed and compared between the two groups.The risk factors of MVCD were analyzed by Logistic regression analysis.Results:Compared with the simple diabetes group, the serum 25(OH)D levels in patients with microangiopathy were significantly lower((44.1±19.0) nmol/L vs.(50.9±20.1) nmol/L). The differences between the two groups were statistically significant ( t=2.156, P<0.05). The incidence of diabetic retinopathy, diabetic nephropathy and peripheral neuropathy in 25 (OH)D<50 nmol/L Group were 37.2%(45/121), 43.0%(52/121), 54.5%(66/121), and those in 25 (OH)D≥50 nmol/L Group were 20.8%(16/77), 16.9%(13/77), 32.5%(25/77). The differences between the two groups were statistically significant (χ 2 values were 5.950, 14.530, 9.231, all P<0.05). Logistic Regression analysis showed that 25(OH)D was a protective factor for MVCD ( OR(95% CI): 1.081(1.030-1.197), P=0.003). Conclusion:The incidence of MVCD is related to the level of Serum 25(OH)D, and serum 25(OH)D is the protective factor of MVCD.
