Treatment:

The goal of treatment for adult Still's disease is to control the symptoms of arthritis. Aspirin and other nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen are usually the first form of treatment.

Prednisone may be used for more severe cases.

If the disease persists for a long time (becomes chronic), medicines that suppress the immune system might be needed. Such medicines include:

• Methotrexate
• Tumor necrosis factor (TNF) antagonists such as Enbrel (etanercept)

Expectations (prognosis):

Studies show that in about 20% of patients, all symptoms go away in a year and never come back. In about 30% of patients, all symptoms go away but then come back several times over the next years.

Symptoms continue for a long-time (chronic) in about half of patients with adult Still's disease.

Complications:

• Arthritis in several joints
• Liver disease
• Pericarditis
• Pleural effusion
• Spleen enlargement
