Still's disease is a rare form of arthritis that is caused by an autoimmune disorder. The exact cause of Still's disease is unknown, but it is believed to be caused by a combination of genetic, environmental, and immunological factors.
Symptoms of Still's Disease
Still's disease is characterized by an intermittent fever, joint pain, and a rash. The fever may come and go over the course of a few days and can reach temperatures as high as 104°F (40°C). The rash associated with Still's disease is most often found on the trunk, arms, and legs and may be raised and red. In addition, people with Still's disease may experience joint pain and swelling, fatigue, and swollen lymph nodes.
Causes of Still's Disease
The exact cause of Still's disease is unknown, but it is believed to be caused by a combination of genetic, environmental, and immunological factors. It is thought that a person's genetic makeup may make them more susceptible to developing the condition. Additionally, environmental triggers, such as infection, can trigger the onset of Still's disease. Finally, immunological factors, such as an overactive immune system, can also play a role.
Diagnosis of Still's Disease
The diagnosis of Still's disease is based on a combination of the patient's symptoms, a physical examination, and laboratory tests. A doctor may order blood tests to check for inflammation as well as tests to rule out other conditions that may have similar symptoms. Additionally, imaging tests, such as X-rays or MRI scans, may be used to look for signs of joint damage.
Treatment of Still's Disease
The treatment of Still's disease typically involves medications to reduce inflammation, fever, and joint pain. Nonsteroidal anti-inflammatory drugs (NSAIDs) may be prescribed to reduce inflammation and pain. Corticosteroids may also be prescribed to reduce inflammation and suppress the immune system. Physical therapy may be used to help maintain joint function and range of motion. In some cases, surgery may be necessary to repair joint damage.
