Low 25-Hydroxyvitamin D Levels on Admission to the Intensive Care Unit May Predispose COVID-19 Pneumonia Patients to a Higher 28-Day Mortality Risk: A Pilot Study on a Greek ICU Cohort. Nutrients. 2020 Dec 9;12(12):3773. doi: 10.3390/nu12123773. PMID: 33316914; PMCID: PMC7764169.

SUMMARY

We aimed to examine whether low intensive care unit (ICU) admission vitamin D levels are associated with worse outcomes of COVID-19 pneumonia. This was a prospective observational study of SARS-CoV2 positive critically ill patients treated in a multidisciplinary ICU. Thirty (30) Greek patients were included, in whom vitamin D level was measured on ICU admission. Eighty (80%) percent of patients had vitamin D deficiency, and the remaining insufficiency. All patients who died within 28 days belonged to the low vitamin D group. Survival analysis showed that the low vitamin D group had a higher 28-day survival absence probability. Critically ill COVID-19 patients who died in the ICU within 28 days appeared to have lower ICU admission vitamin D levels compared to survivors. It seems plausible, therefore, that low vitamin D levels may predispose COVID-19 patients to an increased 28-day mortality risk.
