Retrospective 25 ICU patients in Brazil, showing vitamin D deficiency associated with higher neutrophil-lymphocyte ratio. There appears to be a typo in the mortality percentage for vitamin D deficiency (20% is not valid for the group size of 8).
This is the 70th of 177 COVID-19 sufficiency studies for vitamin D, which collectively show higher levels reduce risk with p<0.0000000001 (1 in 26 vigintillion).
risk of death, 29.4% lower, RR 0.71, p = 1.00, high D levels 3 of 17 (17.6%), low D levels 2 of 8 (25.0%), NNT 14, >20ng/mL.
Effect extraction follows pre-specified rules prioritizing more serious outcomes. Submit updates

Background & aims: Systemic inflammation has been reported as a new predictor for COVID-19 outcomes. Thus, we hypothesized that ICU patients infected by COVID-19 had lower blood vitamin D levels and increased systemic inflammation. Therefore, this is the first Brazilian study to evaluate the vitamin D concentrations and NLR as a systemic inflammation in patients infected by COVID-19 admitted in ICU. Methods: This cross-sectional study selected twenty-six patients from COVID-19 Data Sharing/FAPESP, Brazil. Twenty-five patients were enrolled from a single hospital and those with blood vitamin D and neutrophil and lymphocyte data were included and had all available data analyzed. Patients were divided in two groups: low vitamin D concentration when 20 ng/mL (low Vit D group, n ¼ 8, 5M/3F, 62.7 ± 8.4 years old), and normal vitamin D when > 20 ng/mL (normal Vit D group, n ¼ 17, 9M/8F, 74 ± 8.2 years old). Serum 25-hydroxy-vitamin D, C reactive protein (CRP), and count of neutrophils and lymphocytes concentrations were collected from COVID-19 Data Sharing/FAPESP. Statistical analyses were performed using the Prism version 5.0 and Student T test was applied to verify any difference between the groups. Results: Low vitamin D group had 15.5 ± 3.3 ng/mL of 25OH Vit D concentrations and normal vitamin D group had 35.9 ± 8.8 ng/mL. Although no difference between groups for CRP concentrations (low Vit D: 4.5 ± 3.3 vs. normal Vit D: 4.2 ± 4.0 mg/dL, p ¼ 0.45), we found higher neutrophil count and NLR values in the low Vit D group when compared to normal Vit D group (low Vit D: 6049.8 ± 3719.7 vs. normal Vit D: 3741.8 ± 1704.1 ng/mL, p ¼ 0.02) and (low Vit D: 9.0 ± 8.6 vs. normal Vit D: 4.2 ± 4.0 ng/mL, p ¼ 0.03), respectively. Conclusion: This data sharing-derived cases of COVID-19 in patients admitted at ICU showed that patients infected by COVID-19 had lower serum 25-hydroxy vitamin D and enhanced systemic inflammation when assessed by NLR values.
