Abstract
Purpose We aimed to assess the combined role of vitamin D and albumin serum levels as predictors of COVID-19 disease
progression.
Methods We conducted a prospective observational study on adult patients hospitalized for SARS-CoV-2 pneumonia
(March–September 2020). Vitamin D and albumin serum levels were measured on admission. These variables were categorized in albumin < 3.5 or ≥ 3.5 g/dL and vitamin D < 30 ng/mL or ≥ 30 ng/mL. We excluded patients with known bone
diseases, renal failure, hypercalcemia and/or treated with antiepileptic drugs and steroids, and patients who received previous
vitamin D supplementation. A composite outcome including any ventilatory support, P
aO2/FiO2 ratio, and 60-day mortality
was defined.
Results Sixty-nine patients were enrolled, of whom 50% received non-invasive (NIV) or invasive mechanical ventilation
(IMV), 10% died, whereas 89% and 66% presented low albumin and low vitamin D serum levels, respectively. No correlation between vitamin D and albumin levels was found. In multivariable logistic regression analyses adjusted for sex and
age-corrected comorbidities, patients having albumin < 3.5 g/dL and vitamin D < 30 ng/mL showed a significant increased
risk for all study outcomes, namely NIV/IMV (OR 3.815; 95% CI 1.122–12.966; p = 0.032), NIV/IMV or death (OR 3.173;
95% CI 1.002–10.043; p = 0.049) and PaO2/FIO2 ≤ 100 (OR 3.410; 95% CI 1.138–10.219; p = 0.029).
Conclusion The measurement of both vitamin D and serum albumin levels on COVID-19 patients’ admission, and their
combined evaluation, provides a simple prognostic tool that could be employed to guide prompt clinical decisions.
