Early Treatment Strategy With High-dose Dexamethasone in Patients With SARS-CoV-2

The use of corticosteroids in COVID 19 in hospitalized patients with moderate symptoms has not been adequately studied in randomized clinical trials, the studies and clinical trials having focused on critical or severe patients. The few studies available to date have yielded evidence of low certainty. Our trial postulates that early intervention and treatment with high-dose corticosteroids (20 mg dexamethasone for 3 days) in patients admitted with pneumonia with respiratory failure and moderate elevation of acute phase reactants and proinflammatory cytokines, or with risk factors that condition worse prognosis on admission, and who have not yet developed data on respiratory distress, the development of the cytokine storm could be avoided or minimized, reducing lung tissue damage and progression to severe respiratory failure and, therefore, reducing the need for invasive and noninvasive respiratory therapies, reducing hospital stay and, possibly, reducing associated mortality. Dexamethasone is a potent synthetic glucocorticoid with actions resembling those of steroid hormones. It acts as an anti-inflammatory and immunosuppressant. It is a widely known glucocorticoid, studied and used in the treatment of autoimmune diseases, in oncology patients under chemotherapy to counteract certain side effects of their antitumor treatment, to augment the antiemetic effects of 5-HT3 receptor antagonists, in patients with brain neoplasms (primary or metastatic) to reduce edema, in spinal cord compressions, in certain hematological malignancies, in the treatment of arthropathies, to counteract allergic shock and septic shock, among many other indications for use. It is also used for the diagnosis of diseases related to hypothalamic-pituitary-adrenal axis dysfunction. Recently, following the DEXA-COVID, CoDEX and RECOVERY clinical trials, dexamethasone has been widely used in patients with severe or critical SARS-CoV-2 pneumonia.
