Correlation of vitamin D level with the clinical-radiological severity of COVID-19 in geriatric patients

Abstract

Objective: This study was planned to investigate the effect of 25-OH-Vitamin D (Vit D) deficiency on clinical and radiological findings of coronavirus disease-2019 (COVID-19) in geriatric patients hospitalized due to COVID-19. Material and Method: Seventy-five patients who were treated for COVID-19 were reviewed retrospectively, and grouped in relation with their ages [(1) 65-74, (2) 75-84, (3) >84 years] and the severity of Vit D deficiency [(1) severe deficiency: 30 ng/mL]. The complaints on admission, comorbidities, intensive care unit (ICU) need, length of hospital stay, laboratory data, and mortality of the ones who had and did not have Vit D replacement (n=18/75) were recorded. The patients were analyzed for COVID-19 severity using radiological and clinical markers. Results: Moderate Vit D deficiency (10-20 ng/mL) was frequently detected. When the disease severity and Vit D levels were analyzed, it was found that the disease was more severe (46.6%) in the Vit D 30 ng/ml group, but there was no statistically significant difference among the groups. Low or high Vit D levels did not show any significant correlations with the severity of pneumonia or the thorax CT findings. The intensive care unit (ICU) admission rate was significantly lower in those who had Vit D replacement (p
