Correlation of vitamin D and E plasma levels with the pathophysiology of type 2 diabetes mellitus among adults in Selangor, Malaysia

Poor glycemic status instigated by derangement of insulin signalling mechanism is the leading cause of Type 2 Diabetes Mellitus (T2DM) pathophysiology. Classical risk factors such as obesity, increasing age, sedentary lifestyle and metabolic syndromes have strong association with T2DM. Recent...

Classical risk factors such as obesity, increasing age, sedentary lifestyle and metabolic syndromes have strong association with T2DM. Recent evidence indicates plasma level of vitamin D and E may alter insulin sensitivity to the cells, but its pathophysiology to diabetes remains unclear. The study was aimed to investigate the potential correlation of plasma level of vitamin D and E with glycemic status in T2DM pathophysiology. A cross-sectional study involved 50 DM and 50 non-DM respondents were recruited through convenient sampling. Socio-demographic, medical background, anthropometric measurement and lifestyle behaviours were the risk factors of diabetes and association of plasma level vitamin D and E were the new risk factors that proposed in the current study. SPSS version 22.0 was adopted for the statistical analysis and significant value was set at P<0.05. The outcome of study highlighted poor glycemic status in DM group (9.32±2.61%) with significant different with non-DM (6.67±2.01%) group. The association of poor glycemic status with gender, level of education, ethnicity and family history who is having diabetes were statistically significant (P<0.05) in DM group. Glycemic status [(haemoglobin A1c (HbA1c) and fasting blood glucose (FBG)] and lipid profiles status [high density lipoprotein (HDL), low density lipoprotein (LDL) and total cholesterol (TC)] were significantly different between DM and non-DM groups. Most of the respondent were deficient of plasma vitamin D with mean value 3.43±2.95 ng/mL in non-DM group and 4.44±5.86 ng/mL in DM group which accounted about 82% and 84% respondent in respective groups. Further bivariate analysis with the group of deficiency of vitamin D (<20 ng/mL) with glycemic status (<7% and >7% of HbA1c level) revealed strong association (P<0.05) of deficiency of vitamin D with poor glycemic status (HbA1c and FBG) in DM groups. Lipid profile status (LDL, HDL and TC) were significantly higher (P<0.05) in non-DM group. The calcium level in non-DM was 8.11 mg/dL and DM group was 9.57 mg/dL. Glycemic status (HbA1c, FBG and C-Peptide) and lipid profile status (LDL and HDL) were significantly associated (P<0.05) with calcium plasma level. The distribution of total vitamin E (VE) in plasma was evidently higher in DM group (4.9±4.3 μg/mL) compared to non-DM group (3.97±3.33 μg/mL). Furthermore, the relationship of total VE with deficiency of vitamin D has significantly associated in poor glycemic status (P<0.05) in DM group. At higher level of total VE (>4.9 μg/mL), there was poor glycemic status in DM group. Concurrently, lipid profiles status suggested LDL, HDL and TC were also significantly higher (P<0.05) in DM group at high level of total VE (>4.9 μg/mL). In conclusion, the present study suggested that predisposing of multiple risk factors of T2DM which predominate in poor glycemic status have strong association with deficiency of vitamin D and elevated plasma vitamin E amongst diabetic respondents. Thus, the elucidation of association of vitamin D and E in current study define the involvement of vitamin D in insulin signalling and the role of vitamin E in quenching free radical which both are interplay in T2DM pathophysiology.
