Childhood arthritis (juvenile arthritis or pediatric rheumatic disease) is an umbrella term used to describe any rheumatic disease or chronic arthritis-related condition which affects individuals under the age of 16. Most types are autoimmune disorders.[1]
Juvenile arthritis may last for a few months, years, or becomes a lifelong disease that requires treatment as the child becomes an adult.[2]
Signs and symptoms
[edit]Several types of childhood arthritis exist, including juvenile idiopathic arthritis, juvenile myositis, juvenile lupus, juvenile scleroderma, vasculitis, and fibromyalgia.[3]
General signs of childhood arthritis disorders include:
- Joints: Swollen, stiff, red, warm, and/or painful joints[3]
- Eyes: Painful/dry eyes, sensitivity to light and/or difficulty seeing caused by uveitis[3]
- Skin: Scaly red rash (psoriatic), light spotted pink rash (systemic), butterfly shaped rash across the bridge of the nose and cheeks (lupus) or thick, hardened patches of skin (scleroderma)[3]
- Organs: Digestive tract (diarrhea and bloating), lungs (shortness of breath) and heart[3]
- Other: Fatigue, appetite loss, and/or high, spiking fever[3]
The most common type of childhood arthritis, juvenile idiopathic arthritis (previously known as juvenile rheumatoid arthritis (JRA) or juvenile chronic arthritis (JCA))[4] can be divided into three main forms: The classification is based upon symptoms, number of joints involved and the presence of certain antibodies in the blood.[1][5]
- Polyarticular arthritis is the first type of arthritis, which affects about 30–40% of children with arthritis and is more common in girls than boys.[1][5][6][7] Typically five or more joints are affected (usually smaller joints such as the hands and feet but many also affect the hips, neck, shoulders and jaw).[1][6]
- Oligoarticular (aka pauciarticular) arthritis can be early or late onset and is the second type of arthritis, affecting about 50% of children with juvenile arthritis.[1][5][6] This type affects fewer than four joints (usually the large joints such as knees, ankles or wrists) and may cause eye inflammation in girls with positive anti-nuclear antibodies (ANA).[1][5] Girls younger than eight are more likely to develop this type of arthritis.[4]</ref>[5]
- Systemic disease is the least common form, with 10–20% of children (boys and girls equally) being affected with limited movement, swelling and pain in at least one joint.[1][6] A common symptom of this type is a high, spiking fever of 103 °F (39.4 °C) or higher, lasting for weeks or months, and a rash of pale red spots on the chest, thighs or other parts of the body may be visible.[1]
Cause
[edit]In most cases, juvenile arthritis is caused by the body attacking its own healthy cells and tissues, i.e. autoimmunity, causing the joint to become inflamed and stiff.[8][5] Once the joint has become inflamed and stiff, damage is done to the joint and the growth of the joint may by changed or impaired.[5] The underlying cause in the malfunction of the autoimmune system is unknown; dietary habits and emotional state seem to have no effect on the disease.[4][2]
Diagnosis
[edit]Early diagnosis and treatment by a pediatric rheumatologist or a rheumatologist can help manage inflammation, relieve pain, and prevent joint damage.[1][5] However, it is difficult for doctors to diagnose the disease[9][4] because there is not a single test that doctors can use to diagnose this disease.[2] Physical exams[2], lboratory tests (blood and urine), and various forms of imaging like X-rays may be some of the tests conducted by a doctor.[1][5] Doctors may perform some of the following tests to diagnose the condition[9]
Treatment
[edit]2021 American College of Rheumatology guidelines provide treatment recommendations dependent on the phenotypical presentation.[13] The treatment of most types of juvenile arthritis include medications, physical therapy, splints and in severe cases surgery.[5] Guideline-informed pharmacological include intraarticular glucocorticoids, scheduled non-steroidal anti-inflammatory drugs, disease-modifying anti-rheumatic drugs, and interleukin inhibitors, depending on macrophage involvement and if symptoms are localized or systemic.[13] These treatments are focused on reducing swelling, relieving pain and maintaining full movement of joints.[1] Children are encouraged to be involved in extra-curricular activities, physical activity when possible, and to live a "normal" life.[1][7] Consistent exercise can reduce both pain and immobility, while also improving life quality.[14]
Epidemiology
[edit]In the US it affects about 250,000-294,000 children making it one of the most common groups of childhood diseases.[5]
