Aims. This study aims at assessing the relationship between 25 (OH) vitamin D (25-OHD) levels and microvascular complications in patients with type 2 diabetes mellitus (DM2). Methods. 136 patients (59 ± 11 years) with DM2 (disease duration 8.6 ± 7 years) participated in this cross-sectional study. Anthropometric data, HbA1c, 25-OHD levels, serum creatinine, and urine microalbumin/creatinine ratio were collected. Dilated retinal exam was performed, and diabetic neuropathy was assessed using the United Kingdom Screening Score. Results. Serum 25-OHD correlated negatively with HbA1c (r=-0.20,  P=0.049). Mean 25-OHD levels were lower in subjects with diabetic retinopathy compared to those without retinopathy (12.3 ± 5.5 versus 21.8 ± 13.7, P<0.001) and lower in subjects with diabetic neuropathy compared to those without neuropathy (16.4 ± 10.4 versus 23.5 ± 14.5, P=0.004). After adjustment for BMI, diabetes duration, and smoking, 25-OHD was an independent predictor of HbA1c (β  −0.14; P=0.03). After adjustment for HbA1c, age, smoking, BMI and disease duration, 25-OHD were independent predictors for diabetic retinopathy: OR 2.8 [95% CI 2.1–8.0] and neuropathy: OR 4.5 [95% CI 1.6–12] for vitamin D < 20 versus vitamin D ≥ 20 ng/mL. Conclusion. Low serum 25-OHD level was an independent predictor of HbA1c, diabetic neuropathy, and diabetic retinopathy in patients with DM2.

The aim of our study was to evaluate the effects of vitamin D supplementation on circulating levels of magnesium and selenium in patients with type 2 diabetes mellitus (T2DM). A total of 126 adult Saudi patients (55 men and 71 women, mean age 53.6 ± 10.7 years) with controlled T2DM were randomly recruited for the study. All subjects were given vitamin D3 tablets (2000 IU/day) for six months. Follow-up mean concentrations of serum 25-hydroxyvitamin D [25-(OH) vitamin D] significantly increased in both men (34.1 ± 12.4 to 57.8 ± 17.0 nmol/L) and women (35.7 ± 13.5 to 60.1 ± 18.5 nmol/L, p < 0.001), while levels of parathyroid hormone (PTH) decreased significantly in both men (1.6 ± 0.17 to 0.96 ± 0.10 pmol/L, p = 0.003) and women (1.6 ± 0.17 to 1.0 ± 0.14 pmol/L, p = 0.02). In addition, there was a significant increase in serum levels of selenium and magnesium in men and women (p-values < 0.001 and 0.04, respectively) after follow-up. In women, a significant correlation was observed between delta change (variables at six months-variable at baseline) of serum magnesium versus high-density lipoprotein (HDL)-cholesterol (r = 0.36, p = 0.006) and fasting glucose (r = - 0.33, p = 0.01). In men, there was a significant correlation between serum selenium and triglycerides (r = 0.32, p = 0.04). Vitamin D supplementation improves serum concentrations of magnesium and selenium in a gender-dependent manner, which in turn could affect several cardiometabolic parameters such as glucose and lipids.

Background: Vitamin D is increasingly investigated as having a role in Type 2 Diabetes Mellitus (T2DM) and its cardiovascular and renal complications. Objective: This study aimed to investigate the association between 25-hydroxyvitamin D (25-OHD) and biomarkers of cardiovascular and renal complications, including cystatin-C. Methods: This cross-sectional study involved 117 participants with T2DM that was not complicated with cardiovascular or renal diseases except hypertension. 25-OHD was measured by electrochemiluminescence immunoassay, while cystatin-C was measured by enzyme-linked-immunosorbent-assay. Other biomarkers, including lipids, creatinine, urea and glycemic measures, were determined by the routine biochemistry assays. Results: The prevalence of vitamin D deficiency was 74.36%. There was no significant difference in cardiovascular and renal biomarkers, including glucose, HbA1c, lipids, urea, creatinine and cystatin-C between participants with adequate and deficient vitamin D (p-values>0.05). Participants with adequate vitamin D were older in age, more obese and having lower eGFR (p-values<0.05). 25-OHD was weakly correlated with age, duration of DM, urea, creatinine and inversely correlated with eGFR (rvalues< 0.32, p-values<0.05). Although creatinine and cystatin-C were directly correlated (r=0.42, pvalue< 0.001), cystatin-C and 25-OHD were not correlated (p-value>0.05). Hypertensive participants were more obese, having a longer duration of DM and higher urea and cystatin-C compared to nonhypertensive participants (p-values<0.05). Binary logistic regression analysis revealed that hypertension could be predicted from increased BMI. Conclusion: 25-OHD was not found to be correlated with cardiovascular risk biomarkers, but it was correlated with renal biomarkers, including urea, creatinine and eGFR. Cystatin-C and 25-OHD were not observed to be correlated to each other, but both were correlated to renal function. Obesity was a significant predictor of hypertension.
