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 .
Improvement of vitamin D status via daily intake of fortified yogurt drink either with or without extra calcium ameliorates systemic inflammatory biomarkers, including adipokines, in the subjects with type 2 diabetes.
CONTEXT Systemic inflammation is thought to have a central role in diabetic long-term complications . OBJECTIVE The aim of this study was to investigate the effects of vitamin D either with or without extra calcium on certain inflammatory biomarkers in the subjects with type 2 diabetes ( T2D ) . DESIGN , SETTING , AND PARTICIPANTS This was a double-blind , r and omized , controlled trial conducted over 12 wk in 90 T2D subjects aged 30 - 60 yr from both sexes . INTERVENTION Subjects were r and omly allocated to one of three groups to receive two 250-ml bottles a day of plain Persian yogurt drink or doogh ( PD , containing 150 mg calcium and no detectable vitamin D(3)/250 ml ) , vitamin D-fortified doogh ( DD , containing 500 IU vitamin D(3 ) and 150 mg calcium/250 ml ) , or calcium + vitamin D(3)-fortified doogh ( CDD , containing 500 IU vitamin D(3 ) and 250 mg calcium/250 ml ) . OUTCOME MEASURES The changes in inflammatory markers were evaluated . RESULTS Compared to the baseline values , highly sensitive C-reactive protein , IL-1β , IL-6 , fibrinogen , and retinol binding protein-4 concentrations significantly decreased in both the DD and CDD groups . Although the decrement in highly sensitive C-reactive protein and fibrinogen was more in CDD compared to DD ( -4.0 ± 8.5 vs. -1.3 ± 2.8 mg/liter , and -0.40 ± 0.74 and -0.20 ± 0.52 mg/liter , respectively ) , the differences were not significant . There was a significant increase in serum adiponectin in both the DD and CDD groups ( 51.3 ± 65.3 vs. 57.1 ± 33.8 μg/liter ; P < 0.05 ) . Mean adiponectin changes in CDD were significantly higher than in PD ( P = 0.021 ) . CONCLUSIONS Daily intake of vitamin D-fortified doogh improved inflammatory markers in T2D subjects , and extra calcium conferred additional benefit only for the antiinflammatory adipokine , i.e. adiponectin
