BackgroundVitamin D3 (1,25(OH)2 cholecalciferol) as a treatment for COVID 19 patients is being disputed, and a clear clinical benefit is not being confirmed.MethodsA retrospective evaluation for COVID-19 patients who were treated with various cumulative doses of vitamin D. Data was extracted from the COVID-19 database, it included patients admitted to three hospitals in Amman, Jordan. Characteristics of patients were tabulated and compared for all-cohort, and propensity score index (PSI) adjustment, The comparison was based on two vitamin D strata ((≤ 149,000 i.u. and > 150,000 i.u.). Logistic regression analysis was utilized to predict recovery, the need for oxygen, and all-cause mortality for all-cohort, IPSW, and IPTW patients, based on vitamin D cumulative doses during their hospital stay.Results 1131 all-cohort and 768 PSI-adjusted patients were recruited. Except for antibiotics and antivirals, all other characteristics were balanced (P = NS). There were 1017 patients on vitamin D, 847 received cumulative ≤ 149,000 i.u., and 170 patients received cumulative dose ≥ 150,000 i.u. (Range 1000 – 385000). It was demonstrated that escalating cumulative doses of vitamin D did not contribute to the assessed outcomes; all-cohort patients (OR = 1.000, 95% C.I. 1.000 to 1.000), IPSW (OR = 1.000, 95% C.I. 1.000 to 1.000), and the IPTW (OR = 1.000, 95% C.I. 1.000 to 1.000).Conclusion In our patients’ cohorts, we could not demonstrate a beneficial effect for vitamin D therapy in COVID-19 patients for recovery, the need for home oxygen, and all-cause mortality, by hospital discharge.
