Which condition is a contraindication for the use of corticosteroids?

Cushing's syndrome is indeed a contraindication for the use of corticosteroids. This condition is characterized by an excess of cortisol in the body, which can result from various causes, including adrenal tumors or prolonged use of corticosteroids. Administering additional corticosteroids to a patient who already has Cushing's syndrome can exacerbate the symptoms and lead to complications associated with hypercortisolism.

In contrast, the other conditions listed—rheumatoid arthritis, asthma, and chronic obstructive pulmonary disease (COPD)—are typically treated with corticosteroids due to their anti-inflammatory properties. These corticosteroids help to manage symptoms and reduce inflammation in these conditions, making them effective and often essential in treatment plans.
