Is Vitamin D Important for Elderly Patients in Intensive Care?
Journal Title: Journal of Academic Research in Medicine - Year 2020, Vol 10, Issue 2
Abstract
Objective: According to the World Health Organization’s old age classification, 65-74 years is considered as young-old, 75-84 years as middle-old, and over 85 years as old-old. Effects of vitamin D on cardiac, renal, and endocrine diseases are closely associated with morbidity/mortality in intensive care units. This study evaluated the difference in vitamin D levels of intensive care patients below and above 75 years, and the associations between vitamin D levels and age as well as mortality/organ failure in both groups. Methods: This study was designed as a retrospective, non-interventional, non-drug, observational clinical trial. Age, gender, vitamin D, and acute physiology and chronic health evaluation II (APACHE II) and sequential organ failure assessment scores on admission to the intensive care unit were recorded. Results: Of all patients, 60 were female and 31 were male. The mean age was 77.7±13.8 years. There were 29 patients aged below 75 years and 62 patients above. The mean vitamin D level was 13.7510 ng/mL-1. The mean APACHE II score of patients of or above 75 years was significantly higher than that of patients below 75 years (p=0.024). There was a significant negative correlation between age and vitamin D in patients of or above 75 years (p=0.042). Risk factors associated with vitamin D deficiency include age, gender, lifestyle, ethnic origin, diet, medical history, drugs, and acute critical illness. With aging, the concentration of 7-dehydrocholesterol in the skin decreases, as well as the vitamin D3-forming capacity of the skin. In this study lower vitamin D levels were detected with increasing age in intensive care unit patients. Conclusion: No significant relationship was detected between age and vitamin D levels in patients below 75 years whereas a significant decrease in vitamin D level with increasing age was detected in patients of or above 75 years (p=0,042).
