What is Oligoarticular JIA?
Oligoarticular juvenile idiopathic arthritis (formerly called pauciarthritis or pauciarticular-onset juvenile rheumatoid arthritis) is defined as juvenile idiopathic arthritis (JIA) involving fewer than five joints. It is the most common subgroup, constituting approximately 50 percent of cases of JIA (table 1).
What is extended Oligoarticular juvenile idiopathic arthritis?
Key points. Oligoarticular arthritis is the most common type of JIA in children and teens, affecting up to four joints in the first six months of symptoms. There are two types: oligoarticular-persistent arthritis an oligoarticular-extended arthritis. Both types have a high risk of eye disease called uveitis.
What is the difference between Oligoarthritis and polyarthritis?
Oligoarthritis: Affects four or fewer joints, typically the large ones (knees, ankles, elbows). Most common subtype of JIA. Polyarthritis: Affects five or more joints, often on both sides of the body (both knees, both wrists, etc.).
Is JIA the same as rheumatoid arthritis?
JIA is arthritis that affects one or more joints for at least 6 weeks in a child age 16 or younger. Unlike adult rheumatoid arthritis, which is ongoing (chronic) and lasts a lifetime, children often outgrow JIA. But the disease can affect bone development in a growing child.
What does Pauciarticular mean?
Pauciarticular: Pauciarticular (paw-see-are-tick-you-lar) means that 4 or fewer joints are affected. Pauciarticular is the most common form of JIA; about half of all children with JIA have this type. Pauciarticular disease typically affects large joints, such as the knees.
Is Oligoarthritis rheumatoid arthritis?
Definition. Oligoarthritis is defined as a chronic inflammatory arthritis of unknown origin that begins before the age of 16 and lasts for at least 6 weeks (Table 16–1).
What is Juvenile arthritis?
The most common type of childhood arthritis is juvenile idiopathic arthritis (JIA), also known as juvenile rheumatoid arthritis. Childhood arthritis can cause permanent physical damage to joints. This damage can make it hard for the child to do everyday things like walking or dressing and can result in disability.
Is juvenile arthritis a rare disease?
Juvenile idiopathic arthritis (JIA) is the most common type of arthritis in kids and teens. About 10% – 20% of children with JIA have a rare and serious subtype called systemic juvenile idiopathic arthritis (SJIA).
What body systems are affected by juvenile arthritis?
An autoimmune disease that can affect the joints, skin, internal organs (i.e. heart, kidneys, lungs) and other areas of the body.
What are symptoms of rheumatoid arthritis?
Rheumatoid Arthritis (RA): Rheumatoid arthritis (often called RA) is a chronic (long-standing) disease that damages the joints of the body. Symptoms and signs of rheumatoid arthritis include joint pain, swelling, inflammation, stiffness, warmth, muscle aches, weakness, fever, fatigue, loss of appetite, weight loss, and malaise.
Is inflammatory arthritis the same as rheumatoid arthritis?
Arthritis can be defined as inflammation of the joint or joints resulting in pain and disability, joint swelling, and stiffness whereas rheumatoid arthritis is a type of inflammatory arthritis that causes synovial inflammation. Rheumatoid arthritis is, therefore, a subgroup of arthritis.
Can children get rheumatoid arthritis?
Yes, children can get arthritis. The most common type of arthritis found in children is juvenile idiopathic arthritis (JIA), also known as childhood arthritis or juvenile rheumatoid arthritis.
