Rheumatoid factor-positive polyarticular juvenile idiopathic arthritis (JIA) is a type of JIA that is characterized by the presence of rheumatoid factor (RF) in the blood. It is an autoimmune disorder that affects the joints of children and adolescents. Symptoms include joint pain, swelling, stiffness, and decreased range of motion. Treatment typically involves medications such as non-steroidal anti-inflammatory drugs (NSAIDs), disease-modifying antirheumatic drugs (DMARDs), and biologic agents.

The most common symptoms of rheumatoid factor-positive polyarticular juvenile idiopathic Arthritis (JIA) include:

• Pain and swelling in multiple joints
• Stiffness in the joints, especially in the morning
• Fatigue
• Low-grade fever
• Loss of appetite
• Weight loss
• Anemia
• Rashes
• Eye inflammation
• Swollen lymph nodes

The exact cause of rheumatoid factor-positive polyarticular juvenile idiopathic arthritis (JIA) is unknown. However, it is believed to be an autoimmune disorder, meaning that the body’s immune system mistakenly attacks its own tissues. This can lead to inflammation and damage to the joints. Other possible causes include genetic factors, environmental triggers, and infections.

1. Non-steroidal anti-inflammatory drugs (NSAIDs): These medications reduce inflammation and pain.

2. Disease-modifying antirheumatic drugs (DMARDs): These medications slow the progression of the disease and can help reduce joint damage.

3. Corticosteroids: These medications reduce inflammation and can be used to treat severe flares.

4. Biologic agents: These medications target specific parts of the immune system and can help reduce inflammation and pain.

5. Physical therapy: This can help improve joint function and range of motion.

6. Occupational therapy: This can help improve daily activities and reduce fatigue.

7. Surgery: This may be necessary to repair joint damage.
