Abstract Objectives To evaluate the association of VDR polymorphisms (FokI, TaqI and ApaI) with vitamin D levels and glycemic status in type 2 diabetes patients from Southern India. Methods In this observational study, genotype frequencies and vitamin D levels of 200 cases (type 2 diabetes patients) were compared with 300 controls (unrelated anonymised stored samples of healthy volunteers) from south India. Serum 25 (OH) D levels were measured by immunoassay technique, glycated hemoglobin (HbA1c) was measured using HPLC and genotyping of VDR polymorphisms were carried out using Real time Polymerase Chain Reaction (RT PCR). Results About 69.2% of type 2 diabetes patients were found to have vitamin D deficiency. FokI polymorphism showed variations in serum 25 (OH) D levels, with AA and AG genotypes having significantly lower serum 25 (OH) D levels as compared to GG [13.24 (8.4) ng/ml, 15.02 (7.07) ng/ml and 20.67 (13.64) ng/ml respectively]. There was no difference in HbA1c levels with respect to the vitamin D levels and VDR polymorphisms. Conclusions AA and AG genotypes of FokI polymorphisms are associated with low serum 25 (OH) D levels. However there was no association between VDR polymorphisms and glycemic status in south Indian type 2 diabetes patients.

Vitamin D Levels

Vitamin D plays an important role in decreasing the risk of developing type 2 diabetes by influencing calcium metabolism, thereby reducing β-cell dysfunction and preventing insulin resistance. The findings of research works are contradictory enough, although some of them demonstrated an inverse relationship between vitamin D levels and the incidence of type 2 diabetes. The article describes the biological mechanisms of relationships between vitamin D levels and type 2 diabetes, reviews the results of the studies conducted and summarizes the available data. Key words: vitamin D, type 2 diabetes mellitus, insulin resistance

Vitamin D Levels

Background: Obesity and type 2 diabetes have both rapidly raised during the last periods and are ongoing to increase at a disturbing rate universal. Several clinical and epidemiological researches demonstrated a reverse association between circulating vitamin D levels, central adiposity and the progress of insulin resistance and diabetes. Objective: The target of this work was to elucidate the complex role of vitamin D and the clinical implications of diabetes on metabolic defects related with obesity. Subjects and Methods: This study encompassed 90 diabetic patients (45 obese and 45 non obese) who were attending the National Diabetic Center/ Al-Mustansiriyah University during the period from June 2019 to January 2020; their age range was (35-60) years. All participant underwent clinical and biochemical examinations. Results: A substantial rise (p= 0.01) in waist/hip ratio, body mass index, fasting serum glucose, total cholesterol, triacylglycerol, and low density lipoprotein cholesterol in obese diabetic patients as paralleled to non-obese group. Moreover, there was an elevation in glycated hemoglobin, serum insulin, and homeostasis model assessment for insulin resistance in obese group, but it was not significant. A substantial decrease (p= 0.01) in serum high density lipoprotein cholesterol and vitamin D3 were detected in obese diabetic patients as paralleled to non-obese group.       Also, obese diabetic patients had the higher percent (61%) of D3 deficiency as paralleled to non-obese patients. Conclusions: In the present study, it is found that there is significant increase in blood sugar in the individuals with decreased vitamin D levels, which was related with insulin resistance, decreased β-cell function, and obesity.

Vitamin D Levels

Background: According to a recent World Health Organization (WHO) report, India, with 32 million diabetic individuals, currently has the highest incidence of diabetes worldwide; these numbers are predicted to increase to 80 million by the year 2030. Deficiency of vitamin D has been associated with increased risk of developing Type 2 diabetes mellitus (DM) and cardiovascular diseases. Vitamin D deficiency is highly prevalent in our country. About 70% of adults in both rural and urban areas were found showing manifestations of vitamin D deficiency. Therefore, we designed this study to assess the vitamin D status of the study population by measuring serum 25(OH) D levels, and its association with oxidative stress markers in type 2 diabetes mellitus.Methods: This is a cross sectional study with Group 1 (n=147): Newly diagnosed type 2 diabetics and Group 2 (n=147): Apparently healthy individuals. Blood was collected by venipuncture. 5ml of blood was collected and allowed to clot. Serum was separated and stored in refrigerator to estimate the oxidative stress markers and vitamin D levels. Estimation of vitamin D levels and oxidative stress markers were carried out by commercially available kits.Results: Vitamin D levels are significantly low in newly diagnosed type 2 diabetics when compared to controls (p < 0.000), whereas the FBG levels are significantly high in newly diagnosed type 2 diabetics when compared to controls (p < 0.000). The TAOS levels are significantly low in newly diagnosed type 2 diabetics when compared to controls (p <0.000), whereas the MDA levels are significantly high in newly diagnosed type 2 diabetics when compared to controls (p < 0.000). The oxidative stress marker TAOS (r = 0.71; p < 0.000), was positively correlated and MDA (r = - 0.85; p < 0.000), was negatively with Vitamin D in newly diagnosed type 2 diabetics.Conclusions: From this study, it is concluded that, lower levels of vitamin D is associated with increased oxidative stress. Therapeutic interventions to increase the vitamin D levels and reduce the oxidative stress should be included as a part of treatment inn newly diagnosed type diabetics.

Abstract Background: Vitamin D deficiency is common around the world, but the association between vitamin D deficiency with metabolic syndrome and its associated diseases is unclear.Methods: A subset of 2393 participants from the Nantong Chronic Diseases Study (NCDS) of 2017-2018 were included in this study.The risk of MS and its associated diseases from low vitamin D levels were assessed by genetic scores using two 25(OH)D synthesis single nucleotide polymorphisms (SNPs) (DHCR7-rs12785878 and CYP2R1-rs10741657), one transport SNP (GC-rs2282679) and one catabolism SNP (CYP24A1-rs6013897).Results: Odds Ratios (ORs) for decreased risk of MS and type 2 diabetes (T2D) was 0.73 and 0.79 in the deficient, 0.53 and 0.67 in the insufficient, and 0.54 and 0.60 in the sufficient categories of serum vitamin D levels, respectively. Mendelian randomization analysis showed per 25nmol/L higher genetically instrumented serum 25(OH)D concentration using the two synthesis SNPs: DHCR7+CYP2R1 genes, associated with a 7% lower risk of T2D. The highest tertile vs the lowest tertile of genetic scores using the three SNPs of DHCR7+CYP2R1+GC genes showed a 10% lower risk of T2D. Also, the group with higher genetic scores among these two and three SNPs were both associated with lower risk of abnormal diastolic blood pressure (DBP) (P=0.0162 and 0.0045 respectively).Conclusions: Our Mendelian randomization analysis showed no genetic evidence for a causal role of lower vitamin D level in the development of MS, but showed a causal role in the development of T2D and DBP in middle-aged and elderly participants from rural China.
