Protocol summary

Study aim
1. To determine the effect of oral supplementation by 25(OH)D on serum levels of 25(OH)D and relate this to decrease the incidence of Coronavirus infection in health providers and family members of COVID-19 patients 2. To determine the effect of oral supplementation by 25(OH)D on serum levels of 25(OH)D and relate this to the primary and secondary outcomes of Coronavirus infection in newly affected patients.
Design
A double-blind, randomized controlled trial
Settings and conduct
The project will perform in as COVID-19 centers affiliated to the Tehran University of medical sciences. Subjects include health providers and the patients' relatives with negative COVID-19. Subjects will be allocated to the intervention or placebo groups. The coordinator will determine this with a computer-generated randomization program. The coordinator does not involve the treatment process and data gathering and data analysis. Participants, physicians, data collectors, and project executives are blind to the type of medication (intervention and placebo). Each patient has a specific code. Based on the drug coding, the physician or researcher will provide the drug to the subjects.
Participants/Inclusion and exclusion criteria
Inclusion criteria: not affected by COVID-19 (based on WHO criteria) Exclusion criteria: Ongoing treatment with vitamin D metabolites or analogs or consuming medication affecting bone metabolism History of chronic disorders Inability to give informed consent
Intervention groups
Subjects in the intervention group will receive 1000 IUs of 25(OH)D daily for 8 wks and controls will receive placebo daily for 8 wks.
Main outcome variables
1. The number of new cases with COVID-19 2.Duration of infection 3.Dyspnea experience 4.Duration of hospitalization 5.Admitted to ICU: duration 6.Incubation period 7.Lymphopenia 8.Mortality during 60 days of study

General information

Reason for update
1. the upper limit for calcium is 10.6 mg/dl 2. COVID-19 diagnosis criteria in Iran COVID centers are based on the following criteria: patients over 18 years of age with acute respiratory tract infection symptoms (e.g. fever, cough, dyspnea) with no other etiology that fully explains the clinical presentation accompanied by chest computed tomography (CT) scan findings compatible with Covid-19 or definite diagnosis of Covid-19 with real-time polymerase chain reaction (PCR)
