Reactive arthritis facts
- Reactive arthritis involves inflammation of joints (S), eyes (conjunctivitis), and the genital, urinary, or gastrointestinal systems.
- Reactive arthritis can occur after genital (venereal) infection or bowel infection (dysentery).
- Reactive arthritis shares many features with psoriatic arthritis, ankylosing spondylitis, and the arthritis of Crohn's disease and ulcerative colitis.
- Reactive arthritis can affect the joints, the spine, the eyes, urinary tract, mouth, colon, and heart.
- There is no single laboratory test for diagnosing reactive arthritis. The HLA-B27 genetic marker is commonly found in the blood.
- Treatment of reactive arthritis is directed toward the specific body area(s) inflamed or affected.
What is reactive arthritis?
Reactive arthritis is a chronic form of arthritis featuring the following three conditions: (1) inflamed joints, (2) inflammation of the eyes (conjunctivitis), and (3) inflammation of the genital, urinary, or gastrointestinal systems.
This form of joint inflammation is called "reactive arthritis" because it is felt to involve an immune system that is "reacting" to the presence of bacterial infections in the genital, urinary, or gastrointestinal systems. Accordingly, certain people's immune systems are genetically primed to react aberrantly when these areas are exposed to certain bacteria. The aberrant reaction of the immune system leads to spontaneous inflammation in the joints and eyes. This can be confounding to the patient and the doctor when the infection has long passed at the time of presentation with arthritis or eye inflammation.
Reactive arthritis has, in the past, been referred to as Reiter's syndrome (a term that has lost favor because of Dr. Hans Reiter's dubious past, one of enthusiastically embracing Nazi politics and medical abominations). In addition, Reiter's syndrome would refer to a specific type of reactive arthritis limiting inflammation to eye, urethra, and joints.
Reactive arthritis most frequently occurs in patients in their 30s or 40s, but it can occur at any age. The form of reactive arthritis that occurs after genital infection (venereal) occurs more frequently in males. The form that develops after bowel infection (dysentery) occurs in equal frequency in males and females.
Reactive arthritis is considered a systemic rheumatic disease. This means it can affect other organs than the joints, causing inflammation in tissues such as the eyes, mouth, skin, kidneys, heart, and lungs. Reactive arthritis shares many features with several other arthritic conditions, such as psoriatic arthritis, ankylosing spondylitis, and arthritis associated with Crohn's disease and ulcerative colitis. Each of these arthritic conditions can cause similar disease and inflammation in the spine and other joints, eyes, skin, mouth, and various organs. In view of their similarities and tendency to inflame the spine, these conditions are collectively referred to as "spondyloarthropathies."
