| Scientific title | Effect of 25-hydroxy vitamin D on inflammation and bone-turnover in critically ill patients: a blinded, prospective, randomised, controlled, parallel group trial |
| Study objectives | In prolonged critically ill patients, rapid and full normalisation of the vitamin D status (25(OH)D levels) with 25(OH)D supplements will result in less inflammation and improved calcium and bone metabolism, compared to placebo. |
| Ethics approval(s) | Institutional Review Board of the Catholic University of Leuven School of Medicine approved on the 25th November 2003 (ref: ML2462) |
| Health condition(s) or problem(s) studied | Inflammation/calcium and bone metabolism |
| Intervention | Informed consent will be requested from the next of kin (closest family member or legal guardian) before inclusion in the study. The family member or the patient can withdraw from the trial, at any time, without impact on his treatment or penalty. The investigators confirm that this study concerns a condition that directly threatens patient health and that the adult patient not able to give consent suffers from the condition. The experiment is essential to confirm the results from earlier research in patients who could consent or from other research methods. Upon ICU admission, patients will be randomly allocated to either: 1. The currently advised vitamin D supplement (a daily intravenous [IV] cholecalciferol supplement of ± 200 IU as part of 10 ml of Cernevit (Clinitec-Baxter, Brussels, Belgium) and a daily IV injection of placebo (ethanol 1 ml) 2. The currently advised vitamin D supplement, an IV loading dose of 200 µg and an IV maintenance dose of 15 µg/day of 25(OH)D, from ICU admission onward and continued for 10 days 25(OH)D will be obtained from Solvay Pharmaceuticals and will be dissolved in ethanol by the hospital pharmacy under laminar flow conditions in glass vials, containing 200 µg/1 ml per vial for the loading dose and 15 µg/1 ml per vial for the maintenance dose. A purity control has been performed on the prepared samples using HPLC (official certificate in addendum). Placebo vials will be prepared by the hospital pharmacy (1 ml ethanol per vial). The vials will be blinded by the hospital pharmacy. Parenteral nutrition will be given according to routine clinical practice aiming for 25 non-protein calories per kg bodyweight per day and enteral nutrition will be attempted as early as possible. |
