What is a common indication for prescribing corticosteroids?

Corticosteroids are commonly prescribed for a variety of conditions, one of which is rheumatoid arthritis. This autoimmune disorder leads to chronic inflammation of the joints, and corticosteroids are effective in reducing this inflammation, alleviating pain, and suppressing the immune response that contributes to the disease's progression.

In rheumatoid arthritis, corticosteroids help to manage flares and maintain remission, thus improving the patient's overall quality of life. They are often used in conjunction with disease-modifying antirheumatic drugs (DMARDs) to enhance treatment efficacy.

The other options represent conditions where corticosteroids may not be a first-line treatment or are less commonly associated with corticosteroid use. For example, acute kidney injury may require other supportive management strategies, pneumothorax typically involves procedures and interventions rather than corticosteroids, and influenza is primarily treated with antiviral medications and symptomatic relief rather than corticosteroids.
