Still's Disease, also known as Systemic Juvenile Idiopathic Arthritis, is a type of inflammatory arthritis that affects children under the age of 16. It is characterized by joint pain, swelling, and stiffness, as well as high fevers, a distinctive salmon-colored rash, and enlarged lymph nodes.
The exact cause of Still's Disease is unknown, although it is believed to be an autoimmune disorder in which the body's immune system mistakenly attacks and destroys healthy tissue. It is more common in boys than girls and is usually diagnosed between the ages of two and five.
Symptoms of Still's Disease include high fevers that may spike in the early evening hours (known as “sundowning”), joint pain and swelling in the knees, ankles, wrists, and other joints, a salmon-colored rash that may come and go, enlarged lymph nodes, and fatigue.
Diagnosis of Still's Disease is made through a combination of physical exam, laboratory tests, and imaging tests. Blood tests may be used to detect inflammation and levels of antibodies. X-rays and other imaging tests may be used to look for joint damage or other signs of inflammation.
Treatment of Still's Disease typically involves a combination of medications to reduce inflammation, such as nonsteroidal anti-inflammatory drugs (NSAIDs), corticosteroids, and disease-modifying antirheumatic drugs (DMARDs). Physical therapy may also be recommended to help maintain range of motion in the joints. In severe cases, injectable biologic drugs may be used to reduce inflammation.
Although Still's Disease can be a challenging condition to manage, with proper medical care and treatment, it can be effectively managed and controlled. It is important to work closely with your healthcare provider to ensure the best outcome.
