SUMMARY OBJECTIVE Vitamin D deficiency is not only associated with bone metabolism but also with diabetes mellitus. We aimed to study the possible association between serum vitamin D concentration and HbA1c level in patients with type 2 diabetes mellitus (T2DM) in this retrospective report. METHODS Patients with T2DM were enrolled to the study either in regulated or non-regulated T2DM groups, according to HbA1c levels. An HbA1c level of <8% was considered as relatively controlled and others were considered as poorly controlled T2DM. RESULTS Serum vitamin D levels in poorly controlled T2DM subjects (9.4 (4.9-34) ng/ml) were significantly lower than that of the relatively well regulated T2DM patients (13.5 (3.4-36) ng/ml) (p=0.03). Vitamin D was strongly and inversely correlated with HbA1c levels (r= -0.295, p=0.005). CONCLUSION Whatever the cause or result of the diabetes mellitus, it is clear that lower vitamin D is strongly associated with worse diabetic regulation in T2DM subjects. Randomized controlled larger studies, which research the relation between diabetic regulation and vitamin D status, are needed to claim whether it could be a therapeutic target in future in diabetic subjects.

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.

Objective. Type 2 deiodinase (Dio2) is an enzyme responsible for the conversion of T4 to T3. The Thr92Ala polymorphism has been shown related to an increased risk for developing type 2 diabetes mellitus (T2DM). The aim of this study is to assess the association between this polymorphism and glycemic control in T2DM patients as marked by the HbA1C levels.Design and Methods.The terms “rs225014,” “thr92ala,” “T92A,” or “dio2 a/g” were used to search for eligible studies in the PubMed, Embase, and Cochrane databases and Google Scholar. A systematic review and meta-analysis of studies including both polymorphism testing and glycated hemoglobin (HbA1C) assays were performed.Results. Four studies were selected, totaling 2190 subjects. The pooled mean difference of the studies was 0.48% (95% CI, 0.18–0.77%), indicating that type 2 diabetics homozygous for the Dio2 Thr92Ala polymorphism had higher HbA1C levels.Conclusions. Homozygosity for the Dio2 Thr92Ala polymorphism is associated with higher HbA1C levels in T2DM patients. To confirm this conclusion, more studies of larger populations are needed.
