“…Additionally, genetic changes in vitamin D receptors are associated with an increased risk of DM. A recent cross-sectional study conducted in Tehran, Iran detected a higher prevalence of vitamin D deficiency in patients with than without type 2 DM (37).…”

Impact of Vitamin D Deficiency on Cognitive Functions in Type 2 Diabetic Patients

Objective. We hypothesized that vitamin D-deficient diabetic patients might demonstrate cognitive deficits and therefore investigated this association in patients with diabetes mellitus (DM).Methods. This study comprised 236 patients with type 2 DM (118 with vitamin D deficiency (less than 20 ng/ mL) and 118 without vitamin D deficiency as the control group). All patients were outpatients in the endocrinology clinics of Baskent University, Turkey from 1 October 2013 to 31 January 2014 and, chosen in a randomized manner according to their application time. The serum vitamin D levels were measured and cognitive functions were evaluated using the Mini Mental Status Examination (MMSE).Results. The mean age in the study and control group was 57.02±7.30 and 58.92±7.58 years, respectively (p=0.051). The male:female ratio in the study and control group was 1.00:1.46 and 1.00:2.11, respectively. The study group was further divided into three subgroups: patients with mild, moderate, and severe vitamin D deficiency. The study outcomes revealed no significant relationship between the vitamin D deficiency level and the total score or subscores of the MMSE (p<0.05).Conclusions. These study results do not confirm the hypothesis that vitamin D deficiency unfavorably affects cognitive functions in patients with type 2 DM.

Objective: This study aimed to assess the association between glycemic control status and serum levels of vitamin D3 in Iranian patients with type 2 diabetes (T2D). Materials and methods: This was a cross-sectional study on 452 patients with T2D in Tehran, Iran, performed between September 2019 and September 2020. We assessed the diabetes laboratory test and vitamin D3 level in all participants using the Enzymatic Glucose Oxidase method. Data were analyzed using SPSS version 24. Results: a total of 452 patients were enrolled in this study (mean age: 59.4 ± 11.4 years, 63.5% females). Vitamin D deficiency was reported in half of the participants. Deficient vitamin D was significantly associated with higher mean level of hemoglobin A1c, fasting plasma glucose, total cholesterol, and low-density lipoprotein-cholesterol (p < 0.05). Multiple regression showed that the level of vitamin D3 could be a good predictor of hemoglobin A1c after adjusting for confounding variables affecting the hemoglobin A1c (regression coefficient: 0.442, 95% CI, 0.072-0.811, p = 0.063). Conclusions: With the alarming rates of vitamin D deficiency in patients with T2D, there was a significant direct association between vitamin D3 and hemoglobin A1c levels before and after adjusting for the associated

“…The present results revealed that the number of cases having vitamin D deficiency and insufficiency were significantly higher than that of controls. Vitamin D deficiency and insufficiency were found to be prevalent among type 2 diabetic patients [34][35][36]. When compared with controls, cases showed significant decrease in the mean level of serum vitamin D. This means that deficiency in vitamin D levels are linked to type 2 diabetes.…”
