TERMINOLOGY
Definitions
- Inflammatory arthritis (IA)
- Group of chronic diseases characterized by inflammation of joints
- Commonly autoimmune
- Affects all ages, often striking in peak working and child-rearing age
- Includes
- Rheumatoid arthritis (RA)
- Most common form of IA
- Rheumatoid arthritis (RA)
- Psoriatic arthritis
- ~ 30% of people with psoriasis develop psoriatic arthritis
- Ankylosing spondylitis
- IA that cause pain and stiffness, mainly in back
- Can present as juvenile ankylosing spondylitis, more commonly in boys than girls
- Juvenile idiopathic arthritis
- Most common type of IA in children
- Girls > boys
- Systemic lupus erythematosus
- Joints affected along with other organs (kidneys, skin, brain)
- Gout
- Uric acid crystals form in cartilage and are released into joint fluid, producing pain
- Pseudogout
- Calcium pyrophosphate crystals form in synovial fluid in joints
- Parvovirus arthritis
- Contagious, viral arthritis that causes flu-like symptoms along with other IA symptoms
- Usually resolves on its own within weeks
- 10% of patients may experience ongoing symptoms
- Lyme disease
- Caused by spirochete contracted through bite of infected deer tick
- Produce IA symptoms in its later stages
- Inflammatory arthritis (IA)
