In conclusion , this review supports the hypothesis that hypovitaminosis D is associated with adverse outcomes after diverse surgical procedures .
The importance of vitamin D for musculoskeletal health has long been recognized , and awareness of significant extra-skeletal effects in health and disease is rapidly emerging .
Although it has been possible for many decades to quantify serum markers of vitamin D deficiency , and to correct deficiency at low cost and with high safety , the influence of vitamin D status on post-surgical outcomes has only recently been identified as a research topic of interest .
To the present , these data have not been the subject matter of formal review .
Accordingly , we conducted a systematic review to assess the association between perioperative vitamin D status and outcomes after surgery .
25-hydroxyvitamin D, 1,25-dihydroxyvitamin D and postoperative outcome in cardiac surgery.
CONTEXT Several cohort studies have reported U-shaped or inverse J-shaped associations between circulating 25-hydroxyvitamin D [ 25OHD ] and clinical outcomes . OBJECTIVE We aim ed to investigate in cardiac surgical patients the association of preoperative 25OHD and 1,25-dihydroxyvitamin D3 [ 1,25(OH)2D3 ] levels with the risk of major adverse cardiac and cerebrovascular events ( MACCE ) . DESIGN A prospect i ve cohort study of adult cardiac surgical patients in 2012 - 2013 was used . SETTING The study was conducted at the Heart and Diabetes Center North Rhine-Westphalia , Germany . PATIENTS A total of 3371 adult patients participated in the study . INTERVENTION None Measurements : The main outcome measure was MACCE until discharge . We categorized vitamin D metabolite levels into subgroups and performed multivariable-adjusted logistic regression analysis to estimate odds ratios ( ORs ) of MACCE . Moreover , we performed multiple regression analysis to assess the association of 25OHD and circulating 1,25(OH)2D3 with preoperative parameters . RESULTS As compared with patients in the 25OHD reference category ( 75 - 100 nmol/L ) , the multivariable-adjusted odds ratios ( OR ) of MACCE was significantly higher in patients with deficient 25OHD levels ( < 30 nmol/L ) ( OR = 2.06 [ 95%CI : 1.24 - 3.43 ] ) , but was comparable in patients with 25OHD levels > 100 nmol/L ( OR = 1.16 [ 95 % CI : 0.56 - 2.37 ] ) . Poor kidney function was an important predictor of high 25OHD ( > 100 nmol/L ) and low 1,25(OH)2D3 levels . 1,25(OH)2D3 was not independently associated with the incidence of MACCE . CONCLUSIONS In cardiac surgical patients , deficient but not high 25OHD levels are independently associated with the risk of MACCE . Cohort studies should consider potential interrelationships between kidney function , circulating vitamin D metabolite levels , and clinical outcome
