Males: Generally Lower Vitamin D levels were associated with worse COVID-10
Note: A few % had high level of vitamin D
Objectives: Vitamin D deficiency was previously correlated with incidence and severity of coronavirus disease 2019 (COVID-19). We investigated the association between serum 25-hydroxyvitamin D (25(OH)D) level on admission and radiologic stage and outcome of COVID-19 pneumonia.
Methods: A retrospective observational trial was done on 186 severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-infected individuals hospitalized from March 1, 2020, to April 7, 2020, with combined chest computed tomography (CT) and 25(OH)D measurement on admission. Multivariate regression analysis was performed to study if vitamin D deficiency (25(OH)D <20 ng/mL) correlates with survival independently of confounding comorbidities.
Results: Of the patients with COVID-19, 59% were vitamin D deficient on admission: 47% of females and 67% of males. In particular, male patients with COVID-19 showed progressively lower 25(OH)D with advancing radiologic stage, with deficiency rates increasing from 55% in stage 1 to 74% in stage 3.
Vitamin D deficiency on admission was not confounded by
- age,
- ethnicity,
- chronic lung disease,
- coronary artery disease/hypertension, or
- diabetes
and was associated with mortality (odds ratio [OR], 3.87; 95% confidence interval [CI], 1.30-11.55),
independent of
- age (OR, 1.09; 95% CI, 1.03-1.14),
- chronic lung disease (OR, 3.61; 95% CI, 1.18-11.09), and
- extent of lung damage expressed by chest CT severity score (OR, 1.12; 95% CI, 1.01-1.25).
Conclusions: Low 25(OH)D levels on admission are associated with COVID-19 disease stage and mortality.
