Adults with Still’s disease are fully capable of living for 20, 30 or more years as long as they adhere to reasonable and effective treatment. As long as reasonable treatment is adhered to, there is no difference between the survival period of adult Steele’s disease patients and that of normal people. Moreover, most patients will reach a situation where their disease is stable and under control, and most of them will be able to carry out normal work and life. Therefore, patients with adult Steele’s disease must have the confidence to overcome the disease. Once the diagnosis is established, it is important to adhere to effective treatment and to follow up regularly. Most patients with adult Steele’s disease have a good prognosis, while some patients have self-limiting and some have intermittent attacks. Of course, over time, some patients may eventually develop typical rheumatoid arthritis, or may develop other diseases in combination, and should be followed up regularly.
