Retrospective 2,342 hospitalized COVID-19 patients in Romania with vitamin D levels measured on admission day, showing lower risk of mortality and severe/critical cases with vitamin D levels ≥ 20ng/mL.
risk of death, 30.6% lower, RR 0.69, p = 0.02, high D levels (≥20ng/mL) 61 of 1,148 (5.3%), low D levels (<20ng/mL) 118 of 1,194 (9.9%), adjusted per study, inverted to make RR<1 favor high D levels (≥20ng/mL), odds ratio converted to relative risk, multivariable.

Abstract: Interest in the immunomodulatory function of vitamin D has grown since the COVID-19
pandemic started. Our study investigated the possible association between vitamin D deficiency
and COVID-19 severity, intensive care needs, and mortality in patients hospitalized with COVID19. A prospective cohort study was performed on 2342 COVID-19 hospitalized patients between
April 2020 and May 2022 in a Romanian tertiary hospital for infectious diseases. A multivariate
generalized linear model for binary data was fit with dependent variables: severe/critical form of
COVID-19, intensive care need, and fatal outcome as a function of vitamin D deficiency, controlling
for age, comorbidities, and vaccination status. More than half of the patients (50.9%) were classified
with vitamin D deficiency based on a serum concentration of less than 20 ng/mL. There was a
negative association between vitamin D and age. Vitamin D-deficient patients presented with more
cardiovascular, neurological, and pulmonary diseases, as well as diabetes, and cancer. In multivariate
logistic regression models, vitamin D-deficient patients had higher odds of severe/critical forms of
COVID-19 [OR = 1.23 (95% CI 1.03–1.47), p = 0.023] and higher odds of death [OR = 1.49 (95% CI
1.06–2.08), p = 0.02]. Vitamin D deficiency was associated with disease severity and death outcome in
hospitalized COVID-19 patients.
