Reactive arthritis

Reactive arthritis: Introduction

Reactive arthritis is a rare type of arthritis that causes inflammation of the urinary tract, eyes, skin, mucus membranes, and joints. Reactive arthritis is believed to occur as a reaction to certain infections of the reproductive system and the digestive system.

Infections that can lead to the complication of reactive arthritis include a common sexually transmitted disease called chlamydia. This is the most common cause of reactive arthritis. A less common cause of reactive arthritis is food poisoning due to Salmonella, Shigella, Yersinia or Campylobacter infection. Why some people develop reactive arthritis in reaction to these infections and other people don't is not known. However, having a certain genetic factor called HLA-B27 increases a person's chance of developing reactive arthritis.

Hallmark symptoms of reactive arthritis affect the urinary tract, eyes, skin, mucus membranes, and joints. Complications include the development of chronic arthritis. For details about additional important complications and symptoms, refer to symptoms of reactive arthritis.

Making a diagnosis of reactive arthritis begins with taking a thorough medical history, including symptoms and history of Chlamydia infection or food poisoning, and completing a physical examination. A referral is generally made to a rheumatologist for definitive diagnosis and treatment. There is no specific test that can diagnose reactive arthritis. Diagnosis is made by evaluating the symptoms and interpreting them in conjunction with tests that rule out other diseases and conditions and/or increase the suspicion of a diagnosis of reactive arthritis.

For example, a blood rheumatoid factor (RF) test will generally be positive in rheumatoid arthritis, which has some similar symptoms, but generally negative in reactive arthritis. Other tests may include a C-reactive protein or erythrocyte sedimentation rate, which indicate an inflammatory process occurring somewhere in the body. A chlamydia test can diagnose the presence of a chlamydia infection, one of the infections that can lead to reactive arthritis. A test may also be run to check for the genetic factor HLA-B27, which increases the risk of developing reactive arthritis. X-rays may show some changes that are characteristic of reactive arthritis and may rule-out some other possible causes of symptoms.

It is possible that a diagnosis of reactive arthritis can be missed or delayed because symptoms can vary amongst individuals and can come and go. In addition, some symptoms may be similar to symptoms of other diseases and conditions. For more information on diseases and conditions that can mimic reactive arthritis, refer to misdiagnosis of reactive arthritis.

Treatment for reactive arthritis varies depending on the underlying infection, the severity of symptoms, the presence of complications, a person's age and medical history, and other factors. Reactive arthritis cannot be cured, but treatment can help to reduce symptoms until the disorder resolves spontaneously on its own. Most people with reactive arthritis have a good long-term prognosis and symptoms disappear within about a year. For details on treatments, refer to treatment of reactive arthritis. ...more »

Article Excerpts about Reactive arthritis

This form of arthritis develops after an infection involving the lower urinary tract, bowel, or other organs. It is commonly associated with eye problems, skin rashes, and mouth sores. Reiterís syndrome is an example of reactive arthritis. (Source: excerpt from Questions and Answers About Arthritis and Rheumatic Diseases: NIAMS)

Definitions of Reactive arthritis:

Reactive arthritis is listed as a "rare disease" by the Office of Rare Diseases (ORD) of the National Institutes of Health (NIH). This means that Reactive arthritis, or a subtype of Reactive arthritis, affects less than 200,000 people in the US population.

Ophanet, a consortium of European partners, currently defines a condition rare when it affects 1 person per 2,000. They list Reactive arthritis as a "rare disease".
