A study protocol for vitamin-D level in sepsis and its outcome in patients admitted to the medical intensive care unit

<ns4:p>Vitamin D functions as a prohormone that promotes bone mineralization by regulating calcium and phosphate levels in the skeletal system. It is a fat-soluble vitamin that is required for immunomodulation, cytokine regulation, and cell proliferation. As a result, Vitamin D is a powerful hormone with pleiotropic effects that improve overall health. Sepsis is the leading cause of death in critically unwell people. According to a recent study, numerous trace minerals and nutrients have the ability to alter the human body, and supplementing these nutrients can improve the prognosis of sepsis patients. A considerable number of patients in the intensive care unit (ICU) have low vitamin D levels, a frequent condition that can increase the risk of infectious diseases. According to various studies, severely ill patients admitted to the ICU who have a vitamin D deficiency are at a higher risk of requiring mechanical ventilation and facing a higher likelihood of mortality. Nonetheless, the connection between insufficient vitamin D levels and mortality in sepsis patients remains a topic of debate.</ns4:p>
