The Chinese outbreak of SARS-CoV-2 during 2019 has become pandemic and the most important concerns are the acute respiratory distress syndrome (ARDS) and hyperinflammation developed by the population at risk (elderly and/or having obesity, diabetes, and hypertension) in whom clinical evolution quickly progresses to multi-organ dysfunction and fatal outcome. Immune dysregulation is linked to uncontrolled proinflammatory response characterized by the release of cytokines (cytokines storm). A proper control of this response is mandatory to improve clinical prognosis. In this context, glucocorticoids are able to change the expression of several genes involved in the inflammatory response leading to an improvement in acute respiratory distress. Although there are contradictory data in the literature, in this report we highlight the potential benefits of glucocorticoids as adjuvant therapy for hyperinflammation control; emphasizing that adequate dosage, timing, and delivery are crucial to reduce the dysregulated peripheral-and neuro-inflammatory response with minimal adverse effects. We propose the use of the intranasal route for glucocorticoid administration, which has been shown to effectively control the neuro-and peripheral-inflammatory response using low doses without generating unwanted side effects.
