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 .
Impact of oral 1,25-dihydroxy vitamin D (calcitriol) replacement therapy on coronary artery risk factors in type 2 diabetic patients.
BACKGROUND Observational data suggest that low 25-hyroxyvitamin D is associated with cardiovascular disease ( CVD ) and its risk factors include diabetes , metabolic syndrome , insulin resistance , hypertension , microalbuminuria and inflammation . We examined the differences between risk factors of CVD before and after treatment with calcitriol in type 2 diabetic patients with vitamin D deficiency . METHODS This study was a clinical trial consisting of 119 type 2 diabetic patients . Forty three patients had vitamin D insufficiency ( 25 OH D less than 30 ng/dl ) who underwent calcitriol treatment  with 0.5 microgram per day for 8 weeks . Blood pressure , fasting blood sugar ( FBS ) , glycosylated hemoglobin ( HbA1C ) , lipid profile , high sensitive C-reactive protein ( HsCRP ) , Homocysteine and albumin to creatinine ratio were measured , before and after the treatment period . Then the two sets of results were compared with each other . RESULTS Following treatment with  calcitriol HbA1C , total cholesterol , low density lipoprotein(LDL ) , high density lipoprotein(HDL ) and diastolic blood pressure decreased significantly ( p = 0.01 , 0.01 , 0.04 , 0.001 and 0.04 respectively ) but the changes in other parameters were not significant . CONCLUSION Replacement of vitamin D may have a beneficial effect on some of the risk factors of CVD in diabetic patients
