Analysis of serum vitamin D values did not produce significant correlations with patient characteristics, clinical symptoms or laboratory parameters associated with COVID-19 disease.<\/p>\n<\/div><\/div><\/div><\/div><\/div>
Results<\/span><\/h2><\/div><\/div><\/div>\n- Serum vitamin D was deficient in only 5% of the population, with a mean of 66.6 nmol\/l (26.6 ng\/ml) and range of 17\u2013128 nmol\/L (6.8-51.2 ng\/ml).<\/li>\n
- Diabetes and hypertension were the most frequent comorbidities, in 46.1% and 46.7% of the patients, respectively.<\/li>\n
- Upon admission, 35.9% of patients required 1\u201314 L\/min oxygen, and 30.3% required >15 L\/min; 36.6% required intubation, and 18.7% required non-Invasive ventilation. The number of patients requiring ICU\/HID admissions was 186 out of the 445 (41.8%). The overall mortality rate was 17.7%.<\/li>\n
- There were non-significant correlations between Vitamin D and almost all the parameters except for chronic respiratory diseases.<\/li>\n<\/ul>\n<\/div><\/div><\/div>
