Medical News Today writer Rachel Nall summarizes the various categories of autoimmune arthritis faced today.
Autoimmune arthritis is the name given to a group of arthritis types where a person’s immune system attacks itself. The most common example is rheumatoid arthritis.
When the immune system attacks itself, the result is inflammation in a joint that can cause pain, stiffness, and mobility problems. There are over 100 types of arthritis, and different types cause different symptoms. Rheumatoid arthritis (RA) and psoriatic arthritis are among the most common types of autoimmune arthritis. This article will take a close look at autoimmune arthritis, identify common symptoms, and outline some of the most common treatments currently available to combat arthritis-related joint inflammation. Types of autoimmune arthritis While this list is by no means comprehensive, it represents some of the most common forms of autoimmune arthritis:
- Rheumatoid arthritis: This is the most common type of autoimmune arthritis, which usually causes swelling and pain in the hands, feet, and wrists. An estimated 1.3 million Americanshave RA, 75 percent of which are women.
- Psoriatic arthritis: Psoriatic arthritis can occur in people with a skin condition called psoriasis. Psoriasis causes scaly, patchy areas to build up on the skin. The affected joint areas can be almost anywhere on the body, including the spine, knees, fingers, toes, or more.
- Reactive arthritis: Reactive arthritis occurs in people who have a history of certain bacterial infections, such as Chlamydia , Salmonella, Shigella, or Campylobacter. Along with joint pain, this can cause eye redness, burning with urination, or a rash on the soles of the feet or palms of the hands.
- Ankylosing spondyloarthritis: Ankylosing spondyloarthritis causes arthritis of the spine, resulting in pain and stiffness in the spinal joints.
- Axial spondyloarthritis: This type affects the pelvic joints and the spine.
- Juvenile arthritis: Juvenile arthritis affects an estimated 300,000 children in the United States. It can cause joint pain, eye inflammation, fevers, and rashes. Other names include juvenile idiopathic arthritis, juvenile chronic arthritis, or juvenile RA.
- Palindromic rheumatism: Palindromic rheumatism is a rare type of arthritis that causes episodes or attacks of joint inflammation that then resolve. Palindromic arthritis often affects the fingers, wrists, and knees. Symptoms include pain, swelling, stiffness, and fever.
Each of these conditions can cause a great deal of discomfort and swelling in the joints.
