This meta- analysis suggests that vitamin D supplementation improves indices of glycemic control ( FBG , HOMA-IR , and HbA1C ) in patients with diabetes mellitus .
Hence , vitamin D supplements may be of potential therapeutic value in diabetic patients , as an adjuvant therapy along with other treatments
BACKGROUND AND PURPOSE This systematic review and meta- analysis aim ed to assess the effects of vitamin D supplements on indices of glycemic control [ homeostatic model assessment -insulin resistance ( HOMA-IR ) , hemoglobin A1C ( HbA1C ) , fasting blood glucose ( FBG ) , and quantitative insulin-sensitivity check index ( QUICKI ) and lipid profile in diabetic patients .
Association between serum level of vitamin D and lipid profiles in type 2 diabetic patients in Iran
Background It is suggested that vitamin D deficiency is associated with cardiovascular disease ( CVD ) via its effect on lipid profiles . The objective of this study was to determine the association between fasting serum levels of  25(OH ) D and lipid profiles in patients with type 2 diabetes . Methods This cross-sectional study was conducted on 108 type 2 diabetics . Patients were selected r and omly among members of the Iranian Diabetes Association according to study criteria .  Fasting concentration of 25(OH ) D , calcium , phosphorus , parathyroid hormone ( PTH ) and lipid profiles ( including triglyceride ( TG ) , high-density lipoprotein ( HDL ) , low-density lipoprotein ( LDL ) , and total cholesterol ) were measured . Results The mean serum levels of 25-hydroxyvitamin D ( 25(OH ) D ) and PTH were 53.41 ± 33.25 nmol/l and 40.24 ± 18.24 pmol/l , respectively , in type 2 diabetic patients . Prevalence of vitamin D deficiency was 58.34 % and vitamin D sufficiency and insufficiency combined was 41.66 % . Although in diabetic patients with vitamin D deficiency , serum levels of total cholesterol , TG , and LDL were higher and HDL was lower compared to patients with vitamin D sufficiency , this association was statistically significant only for serum level of TG ( 145.91 ± 79.00 vs. 122.95 ± 55.82 mg/dl ) . Conclusions The results of present study show that serum concentrations of 25(OH ) D were inversely associated with TG . More interventional studies are needed to confirm the relationship between serum concentration of vitamin D  and lipid profile in patients with type 2 diabetes
