Juvenile rheumatoid arthritis

Summary about Disease


Juvenile rheumatoid arthritis (JRA), now more commonly known as juvenile idiopathic arthritis (JIA), is a type of arthritis that affects children and adolescents under the age of 16. It is an autoimmune disease, meaning the body's immune system mistakenly attacks its own cells and tissues. JIA causes inflammation of the joints, leading to pain, swelling, stiffness, and loss of function. It can affect single or multiple joints, and the severity of the disease varies widely from child to child.

Symptoms


Persistent joint pain, swelling, and stiffness, especially in the morning or after inactivity.

Limping.

Decreased range of motion.

Eye inflammation (uveitis), which may cause redness, pain, and blurred vision.

Skin rash.

Fever.

Fatigue.

Loss of appetite.

Delayed growth.

Causes


The exact cause of JIA is unknown. It is believed to be a combination of genetic predisposition and environmental triggers. It is not caused by an infection or injury. The immune system malfunctions and attacks the body's own joint tissues.

Medicine Used


4. Medicine used

Nonsteroidal anti-inflammatory drugs (NSAIDs): Ibuprofen, naproxen, etc., to reduce pain and inflammation.

Disease-modifying antirheumatic drugs (DMARDs): Methotrexate, sulfasalazine, leflunomide, to slow down the progression of the disease.

Biologic agents: Etanercept, adalimumab, infliximab, abatacept, tocilizumab, rituximab, to target specific parts of the immune system.

Corticosteroids: Prednisone, prednisolone, to reduce inflammation quickly, but often used short-term due to side effects.

Eye drops: Corticosteroid or other eye drops for uveitis.

Is Communicable


No, JIA is not communicable. It is not contagious and cannot be spread from person to person.

Precautions


Regular exercise: Low-impact activities such as swimming, cycling, and walking to maintain joint mobility and muscle strength.

Physical therapy: To improve range of motion and reduce pain.

Healthy diet: A balanced diet to maintain a healthy weight and support overall health.

Eye exams: Regular eye exams to detect and treat uveitis.

Good sleep hygiene: Adequate rest to manage fatigue.

Stress management: Techniques such as relaxation exercises and meditation.

Vaccinations: Stay up-to-date on vaccinations, but discuss with your doctor as some medications may affect vaccine efficacy.

How long does an outbreak last?


The duration of JIA outbreaks varies greatly. Some children may experience periods of remission (when symptoms disappear) that can last for months or years. Others may have persistent active disease that requires ongoing treatment. The course of the disease is unpredictable.

How is it diagnosed?


Physical exam: To assess joints for swelling, tenderness, and range of motion.

Medical history: Including symptoms, family history of autoimmune diseases.

Blood tests: Erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) to measure inflammation; rheumatoid factor (RF) and anti-cyclic citrullinated peptide (anti-CCP) antibodies, though often negative in JIA; complete blood count (CBC).

Imaging tests: X-rays, MRI, or ultrasound to assess joint damage.

Eye exam: Slit-lamp examination by an ophthalmologist to detect uveitis.

Exclusion of other conditions: Ruling out other possible causes of joint pain and inflammation.

Diagnostic criteria: Based on the International League of Associations for Rheumatology (ILAR) criteria for JIA subtypes.

Timeline of Symptoms


9. Timeline of symptoms The timeline of symptoms varies greatly. Some children may experience a sudden onset of symptoms, while others may have a gradual development of joint pain and stiffness. The course of the disease can be unpredictable, with periods of remission and flare-ups. There is no set timeline.

Important Considerations


Early diagnosis and treatment are crucial to prevent joint damage and improve long-term outcomes.

JIA requires a multidisciplinary approach involving rheumatologists, ophthalmologists, physical therapists, occupational therapists, and other healthcare professionals.

Parental and family support is essential for managing the disease and ensuring adherence to treatment.

JIA can have a significant impact on a child's quality of life, including school attendance, social activities, and emotional well-being.

Regular follow-up appointments are necessary to monitor disease activity and adjust treatment as needed.

Living with JIA can be challenging, but with appropriate management, children can lead active and fulfilling lives.
