Scientific title
Vitamin D replacement to prevent acute lung injury following oesophagectomy - a randomised placebo controlled trial
Acronym

Study hypothesis
This is a randomised double-blind placebo-controlled study to test the safety and efficacy of rapid vitamin D replacement upon extravascular lung water and markers of alveolar/systemic inflammation in patients undergoing oesophagectomy.
The pilot study was registered in September 2011: www.controlled-trials.com/ISRCTN66719785

Drug names
Primary outcome measure
Extravascular lung water index (EVLWI) at the end of oesophagectomy
Secondary outcome measures
Clinical markers indicative of lung injury:

2. Oxygenation index
3. Development of lung injury / ARDS day 0-28
4. Duration of ventilation and organ failure, survival
5. Safety and tolerability of vitamin D supplementation
6. Plasma indices of endothelial and alveolar epithelial function/ injury
7. Plasma inflammatory response
8. Plasma LL-37 levels
9. Plasma vitamin D status (25D3, 1,25D3 and VDBP)
10. EVLWI post-operative day 1
