Outcome of High Dose Vitamin D on Prognosis of Sepsis Requiring Mechanical Ventilation

Outcome of High Dose Vitamin D on Prognosis of Sepsis Requiring Mechanical Ventilation; A Randomized Controlled Trial

There is a high prevalence of vitamin D deficiency in the critically ill patient population, with approximately 60% of patients found to be vitamin D deficient, (25(OH)D concentrations <20 ng/mL) and an additional 30% of patients being vitamin D insufficient, (25(OH)D = 20-30 ng/mL).Approximately 80% of sepsis/septic shock patients experience respiratory failure and require mechanical ventilation. Furthermore, several studies document that vitamin D deficiency could be associated with poor outcomes in critically ill patient.

Inclusion Criteria:

• Diagnosed with sepsis and required mechanical ventilation (MV) within 24 hours from ICU admission.

• History of therapy with high dose vitamin D3 within previous 6 months.
• History of disorders associated with hypercalcemia
• Cancer as the cause of sepsis.
• Subjects undergoing chemotherapy.
• Immune compromised patients.
• Pneumonia developed < 48 hours following intubation.
• Patients with history of aspiration before intubation.
