METHYLPREDNISOLONE PULSES in HOSPITALIZED PATIENTS with SEVERE COVID-19 PNEUMONIA

ABSTRACT

Background: Pulse glucocorticoid therapy (> 250 mg of prednisone equivalent per day for 1 or a few days) is used in many immuno-inflammatory diseases for its quick and strong anti-inflammatory effect in emergency situations. It was used during in Severe Acute Respiratory Syndrome epidemics with no consistent data regarding its benefits. The efficacy and safety of this therapy associated to dexamethasone in coronavirus disease 2019 (Covid-19) pneumonia are unclear. Methods: We conducted a double-blind, randomized, placebo-controlled trial in hospitalized patients with COVID19-pneumonia. The study population included patients hospitalized for recent-onset Covid-19 pneumonia requiring supplemental oxygen in any delivery mode, except invasive mechanical ventilation, with PaO2/FiO2 between 100 and 300, and a C-reactive protein greater than 5 mg/dl. Patients were randomly assigned to receive 1 gram of methylprednisolone for 3 consecutive days or placebo in addition to standard dexamethasone. The primary outcome was the duration of the patient hospitalization, calculated as the time interval between randomization and hospital discharge without the need of supplementary oxygen. All-cause mortality, survival free from invasive ventilation and safety were also evaluated. Written informed consent was obtained from each patient or from the patient's legally authorized representative if the patient was unable to provide consent. Results: A total of 304 patients underwent randomization in 19 Italian sites between December 21, 2020, and March 10, 2021. Three patients retired the consent to the study one day after randomization, leaving 301 patients eligible for intention to treat analyses. 112 of 151 (74.2%) patients in the pulse methylprednisolone arm and 111 of 150 (74.0%) patients in the placebo arm were discharged from hospital without oxygen (p = 0.528) within 28 days from randomization. We did not observe any significant differences between pulse methylprednisolone and placebo arms in terms of admission to Intensive Care Unit with orotracheal intubation or death (19.9% versus 16.0% respectively;hazard ratio, 1.27;95%CI, 0.74-2.16), or in terms of overall mortality (9.3% versus 11.3% respectively;hazard ratio, 0.82;95%CI, 0.40-1.66). Serious adverse events occurred in 9 patients (6.0%) in the methylprednisolone pulse group and in 12 patients (8.0%) in the placebo group. Conclusion: Methylprednisolone pulse therapy in addition to dexamethasone was not of benefit in patients with COVID-19 pneumonia.
