What is Oligoarticular arthritis?
What is Oligoarticular arthritis?
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).
How many joints is Oligoarticular?
Table 1
| Feature | Oligoarticular JIA | |
|---|---|---|
| Overall | Persistent | |
| Female:male ratio | 3:1 | — |
| Number of joints affected | 1–4 joints in the first 6 months | 1–4 joints throughout the disease course |
| Pattern of arthritis | Affects large joints asymmetrically in the first 6 months (commonly knees and ankles) | Pattern maintained throughout the disease |
What is polyarticular juvenile idiopathic arthritis?
Polyarticular juvenile idiopathic arthritis (formerly called polyarticular-onset juvenile rheumatoid arthritis [RA]) is a subset of juvenile idiopathic arthritis (JIA) that is defined by the presence of more than four affected joints during the first six months of illness [1].
What causes Spondyloarthritis?
The specific causes of most types of spondyloarthritis are unknown, although medical experts have found genetic factors. People who have a gene known as HLA-B27 are at a higher risk of developing ankylosing spondylitis, enteropathic arthritis, psoriatic arthritis, and reactive arthritis.
Does oligoarthritis go away?
Many children will outgrow oligoarthritis by adulthood. In some children, it may spread to eventually involve more joints.
Does JIA become RA?
Some JIA patients with oligoarthritis were diagnosed with RA, and others with spondyloarthritis (SpA) – a type of arthritis that attacks the spine, especially the low back. Almost all kids with enthesitis-related JIA were reclassified as having SpA.
How do you say Oligoarticular?
Oligoarticular (say: oh-lee-go-ar-tik-yoo-lur) JIA occurs in 50% to 60% of young people who have JIA. It is the most common type of JIA in young people. It affects four or fewer joints in the first six months after diagnosis.
What is JIA?
Juvenile idiopathic arthritis (JIA) is a form of arthritis in children. Arthritis causes joint swelling (inflammation) and joint stiffness. JIA is arthritis that affects one or more joints for at least 6 weeks in a child age 16 or younger.
Can you outgrow juvenile 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 are symptoms of spondyloarthritis?
Symptoms of spondyloarthritis vary between patients but may include:
- Longstanding low back pain.
- Back stiffness.
- Back pain and stiffness are typically worse at night and improve with exercise.
- Fatigue.
- Painful swelling of joints.
- Sausage-like appearance of fingers or toes.
- Heel pain.
- Skin and nail changes of psoriasis.
Is Oligoarthritis an autoimmune disease?
Pediatrics in Systemic Autoimmune Diseases Among these, oligoarthritis, polyarthritis RF-negative, and psoriatic arthritis have the highest risk of developing secondary uveitis, especially in female patients [12,13].
Does JIA ever go away?
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.
