Corticosteroid-related Osteonecrosis: The Downstream Consequences of COVID Treatments .

Corticosteroids have become a key therapy for hospitalized patients with severe COVID-19, and recent trials suggest they can lower mortality and help more patients leave hospital sooner. Most of this evidence comes from the RECOVERY trial, which used relatively low doses for short durations. While these findings are encouraging, lessons from the 2003 SARS outbreak offer an important caution. High or prolonged steroid exposure was linked to complications such as osteonecrosis, with risk rising alongside cumulative dose and treatment length. Although comparable harms haven’t yet been documented in COVID-19, the historical signal reminds clinicians to balance clear short-term benefits with careful attention to dosing and duration as evidence continues to evolve.
