Efficacy and Safety Comparison of Two Different Doses of Dexamethasone in Hospitalized Patients with COVID-19: A Randomized Clinical Trial
Abstract
ABSTRACT Objective: The current study aims to investigate high- versus low-dose dexamethasone administration to control the disease with minor complications. Methods: The current multicentric randomized clinical trial was conducted on 119 patients with COVID-19 pneumonia and assigned into two groups of low-dose (8 mg daily intravenous dose for at least 7 days or until discharge) (n = 61) versus high-dose dexamethasone (24 mg for 3 days followed by daily 8 mg for the at least 4 days later or until discharge) (n = 58) during 2020–2021. Oxygen saturation, dyspnea severity based on the Borg scale, and laboratory indices were assessed at 3, 5, and 7 days of corticosteroid therapy. Patients were compared regarding the length of hospitalization, intensive care unit (ICU) admission requirement, and noninvasive or invasive ventilation. The other investigations included corticosteroid-related adverse effects and mortality rates within a month after the medications. Findings: Oxygen saturation, Borg scale, and C-reactive protein levels were significantly altered by the time in both the groups (P < 0.05). In contrast, the trend of improvements in Borg scale (P = 0.007) and lactate dehydrogenase levels (P = 0.034) were superior in high-dose treated cases. Drug-related adverse (P = 0.809), mortality rate (P = 0.612), hospitalization duration (P = 0.312), ICU admission requirement (P = 0.483), and noninvasive (P = 0.396) and invasive ventilation (P = 0.420) did not differ between the…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 119 participants or records.
