What is the recommended treatment for newly diagnosed severe Crohn disease in a young woman?

In the context of severe Crohn's disease, especially in the setting of a newly diagnosed patient, the initial treatment typically involves the use of corticosteroids. These medications, such as prednisone, are effective in quickly reducing inflammation and providing relief from symptoms. Corticosteroids work by suppressing the immune response that contributes to the inflammatory process in the gut, which is especially important in a severe case where significant symptoms or complications may be present.

This approach is generally preferred for rapid symptom control and stabilization of the condition. Once the patient has responded to steroids, it may be appropriate to transition to other long-term immunosuppressive therapies, such as azathioprine, to maintain remission and minimize reliance on steroids.

The other options, while they may play a role in the overall management of Crohn's disease, are not the primary choice for initial treatment in severe cases. Antibiotics like ciprofloxacin and metronidazole may be considered for specific indications, such as infections or abscesses, but they do not address the underlying inflammation directly as effectively as corticosteroids do in the acute phase of severe disease. Therefore, starting with prednisone is a well-established and widely accepted approach in treating severe flare-ups of Crohn's disease.
