ADULT STILLS DISEASE
Adult Still's disease (ASD) is an inflammatory condition in which you may experience daily spiking fevers, have achy or swollen joints and discover a salmon-pink rash appearing on your body. The disorder is rare. As it progresses, Adult Still's disease may lead to chronic arthritis and other complications.
Still's disease is named after an English doctor named George Still, who described the condition in children in 1896. Still's disease is now known as systemic onset juvenile rheumatoid arthritis (JRA). In 1971, the term "Adult Still's disease" was used to describe adults who had a condition similar to systemic onset JRA. There's no cure for Adult Still's disease; however, treatment may offer symptom relief for Adult Still's disease and help prevent complications.
Signs and symptoms
Most people with Adult Still's disease experience a combination of the following signs and symptoms:
§ Fever. You may experience a daily fever of at least 102 F for a week or longer. The fever usually peaks in the late afternoon or early evening. Between episodes, your temperature will likely return to normal.
§ Rash. A salmon-pink bumpy or flat rash may come and go with the fever. The rash usually appears on your trunk, arms or legs. Physical contact such as rubbing your skin or exposing it to hot water may provoke the rash to appear.
§ Achy and swollen joints. You may find that your joints — especially your knees, wrists, ankles and elbows — are stiff, painful and inflamed. Usually, the joint discomfort lasts at least two weeks.
§ Muscle pain. Muscular pain associated with Adult Still's disease usually ebbs and flows with the fever. It may be severe enough to disrupt your daily activities.
Other signs and symptoms may include:
§ Sore throat
§ Swollen lymph nodes in your neck
§ Enlarged liver or spleen
Having any of these signs or symptoms doesn't necessarily mean that you have Adult Still's disease. The signs and symptoms of this disorder may mimic those of other conditions. These include other infectious diseases such as infectious mononucleosis, a type of cancer called lymphoma or other rheumatic diseases, including rheumatoid arthritis.
