RCT on calcifediol (25-hydroxyvitamin D) treatment for hospitalized COVID-19 patients showing significantly reduced intensive care unit admissions. All patients received standard care including HCQ+AZ. Significantly lower ICU admission with the addition of calcifediol - adjusted odds ratio 0.03 [0.003-0.25]. No deaths for calcifediol (0/50), 2 deaths for SOC (2/26).

Abstract: Since January 2020 Elsevier has created a COVID-19 resource centre with
free information in English and Mandarin on the novel coronavirus COVID19. The COVID-19 resource centre is hosted on Elsevier Connect, the
company's public news and information website.
Elsevier hereby grants permission to make all its COVID-19-related
research that is available on the COVID-19 resource centre - including this
research content - immediately available in PubMed Central and other
publicly funded repositories, such as the WHO COVID database with rights
for unrestricted research re-use and analyses in any form or by any means
with acknowledgement of the original source. These permissions are
granted for free by Elsevier for as long as the COVID-19 resource centre
remains active.

Objective: The vitamin D endocrine system may have a variety of actions on cells and tissues involved in COVID19 progression especially by decreasing the Acute Respiratory Distress Syndrome. Calcifediol can rapidly in
crease serum 25OHD concentration. We therefore evaluated the effect of calcifediol treatment, on Intensive Care
Unit Admission and Mortality rate among Spanish patients hospitalized for COVID-19.
Design: Parallel pilot randomized open label, double-masked clinical trial.
Setting: University hospital setting (Reina Sofia University Hospital, Córdoba Spain.)
Participants: 76 consecutive patients hospitalized with COVID-19 infection, clinical picture of acute respiratory
infection, confirmed by a radiographic pattern of viral pneumonia..
