Reactive arthritis in Child
See also in: Anogenital,Nail and Distal DigitAlerts and Notices
Synopsis
Reactive arthritis was initially described after infections with specific bacteria: Chlamydia trachomatis, Shigella, Salmonella, Yersinia, and Campylobacter. Clostridioides difficile, Giardia, and other atypical infections have also been implicated as triggers for reactive arthritis. It is unclear how infections trigger the disease. In recent studies, Chlamydia has been isolated from the joint capsule in some cases.
It occurs most commonly in men ages 20-40. It can be especially common in patients with human immunodeficiency virus (HIV) infection and present with more severe symptoms. In children, the condition is rare. It is most commonly triggered by an enteric infection in young children and by a genitourinary infection in teenagers.
The hallmark features of reactive arthritis include urethritis, eye symptoms (conjunctivitis, iritis, uveitis), oral lesions, arthritis, and spinal involvement. Children often do not present with the full triad of conjunctivitis, urethritis, and arthritis. Conjunctivitis can precede other symptoms and signs. Asymmetric heel and knee pain due to joint and ligamentous inflammation is common in children. Additional symptoms include fever, malaise, anorexia, and weight loss.
For most patients, reactive arthritis is a self-limited disease, and they recover completely within 2-6 months. A chronic arthritis may persist in a minority, usually in association with HLA-B27 phenotype. Other patients can develop recurrent episodes of reactive arthritis after encountering the same organism.

Patient Information for Reactive arthritis in Child
Overview
Reactive arthritis (formerly called Reiter syndrome) is a type of arthritis triggered by infection. The infection causes an autoimmune reaction of arthritic joint pain, stiffness, and inflammation. The joints often affected are your knees, ankles, and joints in your upper extremities. The arthritis may also occur along the spine and lower back. A small number of patients also have inflammation in the urethra, eyes, and skin.Reactive arthritis is a rare condition that usually goes away on its own in as few as 2-6 months. Less commonly, it can persist beyond 6 months (referred to as chronic reactive arthritis). It can also recur. Foodborne illnesses and sexually transmitted chlamydial infections are both common precursors to reactive arthritis.
Who’s At Risk
Reactive arthritis most commonly affects young adults (aged 20-40). Women and men develop reactive arthritis to foodborne infections at about the same rate, but men have a higher chance of developing reactive arthritis due to sexually transmitted bacteria. A family history of reactive arthritis also increases the likelihood of developing reactive arthritis.The following bacteria have been known to cause reactive arthritis:
- Chlamydia
- Salmonella
- Yersinia
- Campylobacter
- Shigella
- Clostridioides difficile
- Giardia
Signs & Symptoms
The symptoms of reactive arthritis typically begin 1-4 weeks after the initial infection. They may include:- Joint pain and swelling
- Eye inflammation or pink eye
- Increased frequency and discomfort during urination
- Swollen toes and fingers (sausage digits)
- Fever, fatigue, and weight loss
- Changes in fingernails and toenails (ridging, peeling, discoloration)
- Some people have changes in bowel movements, such as diarrhea or constipation
Self-Care Guidelines
These measures can be taken to reduce your risk of developing an infection that could lead to reactive arthritis:- Store food at its proper temperature and cook it properly
- Use condoms to lower your risk of sexually transmitted infections
These measures can be taken to manage symptoms:
- Talk to your doctor about following an anti-inflammatory diet
- Exercise regularly, preferably with activities easy on the joints (swimming, walking, bicycling)
- Do stretching exercises to maintain joint movement and range of motion
When to Seek Medical Care
Contact your health care provider if you have joint pain or swelling for longer than a week.Treatments
If your reactive arthritis is caused by a bacterial infection that is still active, your health care provider may prescribe an antibiotic.To relieve the symptoms of arthritis, the health care provider may recommend:
- Nonsteroidal anti-inflammatory drugs (NSAIDs) to relieve inflammation, such as ibuprofen
- Corticosteroid injections into joints to reduce inflammation
- Some types of rheumatoid arthritis drugs help to reduce pain
- Physical therapy to increase strength of joints, joint flexibility, and range of motion
