1. What is Juvenile Idiopathic Arthritis (JIA)?

Juvenile Idiopathic Arthritis (JIA) is a group of inflammatory joint diseases that begin before the age of 16 years. It causes persistent joint inflammation lasting at least 6 weeks. JIA is an autoimmune or autoinflammatory condition and is not caused by injury or infection.

2. What are the common symptoms of JIA?

Common symptoms include joint pain, swelling, stiffness, and reduced movement. Morning stiffness and limping, especially after waking or prolonged rest, are common. Some children may also develop fever, skin rash, fatigue, or reduced activity.

3. Can JIA affect a child's growth and development?

Yes. Persistent inflammation can interfere with normal growth, muscle development, and bone health. Inflammation around an affected joint may also alter the growth of that limb. Early and effective treatment helps minimize these complications.

4. What are the different types of JIA?

JIA includes several subtypes with different clinical features. Major categories include oligoarticular, polyarticular, systemic JIA, enthesitis-related arthritis, juvenile psoriatic arthritis, and undifferentiated arthritis. Treatment varies according to the subtype and severity.

5. Can JIA affect the eyes?

Yes. Some children with JIA can develop uveitis, an inflammation inside the eye. It may occur without pain, redness, or other obvious symptoms. Regular screening by an ophthalmologist is therefore important, particularly in children at higher risk.

6. How is JIA diagnosed?

There is no single test that confirms JIA. Diagnosis is based on the child's symptoms, joint examination, and exclusion of other causes of arthritis. Blood tests and imaging may help assess inflammation, classify the disease, and guide treatment.

7. Is JIA curable?

There is currently no single definitive cure for all forms of JIA. However, modern treatments can control inflammation effectively, and many children achieve remission or very low disease activity. Early treatment helps protect the joints and maintain normal activities.

8. How is JIA treated?

Treatment is individualized according to the type and severity of JIA. Options may include NSAIDs, joint steroid injections, DMARDs such as methotrexate, biologic medicines, and targeted therapies. Physiotherapy and regular exercise are also important components of care.

9. Can children with JIA participate in sports and physical activities?

Yes. Regular physical activity is encouraged to maintain joint mobility, muscle strength, bone health, and overall fitness. Swimming, cycling, and other age-appropriate activities can be beneficial. Activities may need temporary modification during significant disease flares.

10. Will my child outgrow JIA?

The course of JIA varies from child to child. Some children achieve long-term remission, while others may continue to have active disease into adulthood. Early diagnosis, appropriate treatment, and regular rheumatology follow-up help prevent joint damage and preserve function.
