Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: To determine whether a weight based enteral loading dose protocol can rapidly normalize vitamin D levels in critically ill children;Secondary Objective: To evaluate whether the weight based vitamin D loading protocol, when compared with usual care, results in: 1. Greater occurrence of vitamin D related adverse events (e.g. hypercalcemia, hypercalciuria) 2. Improved vitamin D axis functioning (e.g. active hormone levels, calcium metabolism) 3. Differences in blood measures of inflammation and innate immunity (e.g. CRP, procalcitonin;Primary end point(s): To determine whether loading dose therapy can rapidly normalize vitamin D status we will measure blood 25(OH)D concentration. More specifically, our primary outcome is the proportion of critically ill children who achieve blood 25(OH)D concentration above 75 nmol/L by day 7. 25(OH)D is widely regarded as the best indicator of vitamin D status;Timepoint(s) of evaluation of this end point: up to 2 years | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): Vitamin D related adverse events Hypercalcemia – We will define hypercalcemia as an ionized calcium level above 1.40 mmol/L (children under 8 weeks as > 1.45 mmol/L) Hypercalcuria – We will identify hypercalcuria using calcium-creatinine ratios, defined using age specific norms and thresholds;Timepoint(s) of evaluation of this end point: up to 2 years | — |
