Juvenile idiopathic arthritis, formerly known as juvenile rheumatoid arthritis, is the most common form of arthritis in children under the age of 16. It is a long‑lasting condition in which the body’s immune system mistakenly attacks the tissues of the joints, causing inflammation. This leads to joint pain, swelling, stiffness, and reduced movement, which may be most noticeable in the morning or after rest.
The most common signs and symptoms of juvenile idiopathic arthritis are:
Juvenile idiopathic arthritis is a complex autoimmune disease—its exact cause is not fully known, but researchers believe several factors contribute to its development.
Diagnosing juvenile idiopathic arthritis can be hard because there is no single test that proves it. Instead, doctors make the diagnosis by carefully reviewing symptoms, performing physical examinations, and using blood and imaging tests to rule out other causes and support the diagnosis.
The main risk factors for juvenile idiopathic arthritis (JIA) are explained below.
Gender: Girls are more likely than boys to develop many forms of JIA, especially the oligoarticular and polyarticular types.
Genetics and family history: Certain genes and inherited traits may make a child more susceptible to JIA. A family history of autoimmune or rheumatic diseases suggests a higher risk, although JIA can still occur in children with no family history.
Age: JIA most often occurs in children under 16, with many cases beginning between about 2 and 3 years old. This age range is when the condition is most likely to develop.
Immune system abnormalities : Since JIA is an autoimmune disease, children whose immune systems are more likely to attack their own tissues may be at higher risk. This includes genetic factors that influence immune response.
Environmental exposures : Some studies suggest that exposure to cigarette smoke before birth or in early life and certain air pollutants may be linked with a higher chance of developing JIA, though more research is needed to confirm these associations.
There is no cure for JIA, but treatment aims to reduce pain and swelling, protect joints from damage, maintain movement and strength, and help the child stay active and healthy.
Nonsteroidal Anti‑Inflammatory Drugs (NSAIDs): NSAIDs like ibuprofen or naproxen help reduce joint pain, swelling, and stiffness. They are often the first medicines used, especially when only a few joints are involved.
Disease‑Modifying Antirheumatic Drugs (DMARDs): DMARDs such as methotrexate act on the immune system to slow the disease process and prevent long‑term joint damage. They are used when symptoms are more persistent or severe.
Biologic Agents: Biologics are newer medications that target specific parts of the immune system driving inflammation. They are often used when DMARDs alone are not enough to control symptoms.
Corticosteroids: Steroids like prednisone or injections directly into a joint reduce inflammation quickly, especially during severe flare‑ups. They are usually used for the shortest possible time because of side effects.
Physical and Occupational Therapy: Therapists help with exercises to maintain joint flexibility, strength, and daily function. They may also recommend splints or supports and teach pain‑reducing techniques.
Lifestyle and Supportive Measures: Regular exercise, balanced nutrition, and healthy routines help children stay active, support joint health, and maintain overall well‑being as part of long‑term management
Self-Care and Supportive Measures: Along with medication, simple daily care helps jock itch heal and stay away. Wash the groin area with mild soap and dry completely, keep the skin cool and dry, and wear loose, breathable clothing like cotton. Change underwear and workout clothes every day, especially after sweating, and don’t share towels or clothing with others. These steps reduce moisture and help the fungus stop growing.
