Summary

To evaluate the role of vitamin D supplementation in critically ill children with respiratory diseases regarding their outcome.

Detailed description

Vitamin D is involved in the process of immunomodulation, especially in the context of autoimmunity . Vitamin D has multiple pharmacological effects, such as alleviating the inflammatory response, promoting phagocytosis, and inducing lymphocyte proliferation . previous studies have demonstrated that patients with lower serum vitamin D levels had a longer length of hospital stay and might have an independent relationship with the duration of mechanical ventilation (MV) in critically ill children . Approved Vitamin D Supplementation Regimens: The recommended daily allowance (RDA) or adequate intake (AI) suggested by the Institute of Medicine (IOM) and supported by Health Canada are 400 IU for infants and 600 IU for older children. Approved High-Dose Regimens: In addition to RDA, the IOM provides a higher age-specific dose called the tolerable upper intake level (UL), which ranges from 1,000 to 4,000 IU.
