5. Study Description

Brief Summary
Although vitamin D is known to play a major role in multiple organ functions in healthy adults, including bone homeostasis, its role in the unique population of orthopaedic polytrauma patients has not been well described. The aim of this therapeutic randomized placebo-controlled feasibility study is to determine the effect of vitamin D supplementation initiated on admission on patients' 25(OH)-D level, bone turnover markers, and clinical outcomes in a cohort of adult orthopaedic polytrauma patients. Polytrauma patients with one or more orthopaedic injuries admitted to an urban Level I trauma center will be screened for eligibility based upon strict inclusion and exclusion criteria. Sixty patients meeting the criteria will be consented, enrolled and randomized in a 1:1 ratio to intervention and control (placebo) arm. Baseline 25(OH)-D and bone turnover marker levels will be drawn for all the patients on admission, and the intervention arm will receive a one-time dose of ergocalciferol (Vitamin D2) 400,000 IU shortly after enrollment. The labs will be repeated 7 days after the initial draw or at discharge, whichever occurs first. Patients' daily immobilization status, baseline characteristics and clinical outcomes will be recorded. Statistical methods will be used to assess whether there is a difference in 25(OH)-D and bone turnover markers levels associated with the intervention.
Detailed Description
Sixty polytrauma patients presenting to Jacobi Medical Center will be screened for eligibility according to strict inclusion and exclusion criteria by study personnel on admission. Medical history, physical examination, and laboratory findings will be collected and assessed to ensure that patients meet the inclusion and exclusion criteria. Eligible subjects will be enrolled after obtaining informed consent from either the subject or health care proxy if the subject is not able to participate in the decision-making process secondary to his injuries or mental status. As this dose of vitamin D has not been previously studied in pregnant subjects, female subjects will be counseled on potential pregnancy risks and will undergo urine pregnancy testing prior to administration of the investigational agent/placebo. Female patients testing positive for pregnancy will be removed from the study. Upon enrollment, study personnel will assign subjects a study ID and record this information in a password-protected data collection document. All enrolled subjects will have blood draws by phlebotomy or nursing staff for the above-mentioned bone turnover markers once consent is obtained. This will include specimen collection and processing for the following serum levels in both study arms: 25(OH)-D, PTH, collagen type I C-telopeptide, calcium, phosphorus, osteocalcin, and alkaline phosphatase. This initial specimen collection will occur in the interval between 0 and 72 hours of hospital admission. Collected specimen will be assigned unique identifiers corresponding to patients' study IDs and delivered to core labs at Jacobi Medical Center. From there, the specimen will be sent to an outside testing facility (Northwell Laboratories, Lake Success, NY), where specimen processing will occur. Normal laboratory values will be established by the outside testing facility according to CLIA standards. The study personnel will liaise with the JMC Main or Satellite Pharmacy to alert them regarding newly enrolled study subjects. The pharmacist will then assign patients according to randomization algorithm in a 1:1 ratio to intervention and control arms, with 30 patients in each group by the end of the study accrual. The pharmacist will then prepare and transport the investigational agent or placebo to the subject's location for administration by nursing staff. The intervention cohort will receive 400,000IU liquid ergocalciferol (50cc of 8000IU/cc Calcidol solution) via oral, NG tube, or gastrostomy route. The control cohort will receive 50cc of propylene glycol as placebo via oral, NG tube, or gastrostomy route. A repeat specimen collection of above-mentioned bone turnover markers will commence either at 7 days if patient is still inpatient, or at discharge, whichever occurs first. The specimens obtained at that time will be treated in the same manner as the initial specimens. For each enrolled subject, the investigators will collect data from hospital presentation to discharge on standard demographics, routine laboratory results, clinical and injury characteristics and hospital course data (length of stay, in-hospital mortality, mobilization status, associated inpatient procedures and complications).
