Retrospective 413 hospitalized COVID-19 patients in Turkey showing vitamin D deficiency associated with higher CRP, fibrinogen, neutrophils, and hematocrit. There was no significant difference for length of stay.
This is the 183rd of 187 COVID-19 sufficiency studies for vitamin D, which collectively show higher levels reduce risk with p<0.0000000001 (1 in 11 vigintillion).
hospitalization time, 13.5% lower, relative time 0.87, p = 0.33, high D levels 374, low D levels 39.
Effect extraction follows pre-specified rules prioritizing more serious outcomes. Submit updates

Although some recent studies have shown that serum 25-hydroxyvitamin D (25(OH)D) may be effective on the course of COVID-19 disease, the results obtained are still controversial. Therefore, in this study, it was aimed to examine whether there are differences in terms of age, gender, length of hospital stay, biochemical and hematological parameters between those with and without serum 25(OH)D deficiency in COVID-19 patients. Material and Method: The data of 413 patients hospitalized in Ankara Pursaklar State Hospital whose COVID-19 positivity was revealed by PCR test were evaluated retrospectively. Those with less than serum 25(OH)D (<20 ng/mL) were considered as vitamin D deficient group. Results: It was observed that there was a significant difference between the groups with and without serum 25(OH)D deficiency in terms of biochemical parameters total bilirubin (p=0.007), potassium (<0.05) and glucose (p=0.038) values. CRP (p=0.051) and fibrinogen (p=0.048) values, which are factors of inflammation and coagulation, were found to be significantly higher in the group with 25(OH)D deficiency. Similarly, hematocrit (p<0.05) and neutrophil count (p<0.001), which are hematological parameters, increased significantly in patients with 25(OH)D deficiency. There were no differences in age, gender and length of hospital stay between the groups with and without 25(OH)D deficiency. Conclusion: Our findings showed that 25(OH)D deficiency in hospitalized COVID-19 patients was associated with some biochemical, hematological and inflammatory factors, but not with age, gender and length of hospital stay.
