Reactive Arthritis: Causes, Symptoms, and Treatment
Reactive arthritis, also known as Reiter's syndrome, is a condition that develops in response to an infection in another part of the body. It's an autoimmune disease, meaning the body's immune system mistakenly attacks its own tissues, leading to joint inflammation. This condition can cause significant discomfort and disrupt daily activities, but understanding its causes, symptoms, and treatment options can help manage it effectively.
What is Reactive Arthritis?
Reactive arthritis is a type of inflammatory arthritis that typically follows an infection, often in the intestines, urinary tract, or genitals. The condition is characterized by pain and swelling in the joints, particularly in the knees, ankles, and feet. It can also affect the eyes, skin, and urinary tract.
Causes of Reactive Arthritis
The exact cause of reactive arthritis isn't fully understood, but it generally occurs after a bacterial infection. Common bacteria associated with reactive arthritis include:
- Chlamydia trachomatis: Often transmitted through sexual contact.
- Salmonella, Shigella, Yersinia, and Campylobacter: Typically contracted through contaminated food.
When the body fights off these infections, the immune response can sometimes continue to target the joints, causing inflammation and pain.
Symptoms of Reactive Arthritis
Symptoms of reactive arthritis usually appear within 1 to 4 weeks after the initial infection. The symptoms can vary in severity and may include:
- Joint Pain and Swelling: Often affects the knees, ankles, and feet. The pain can be severe and is usually worse in the morning.
- Eye Inflammation: This can cause redness, pain, and blurred vision, known as conjunctivitis or uveitis.
- Urinary Problems: Painful urination or increased frequency of urination, typically associated with urethritis.
- Skin Issues: Rashes or sores on the skin and mouth, such as keratoderma blennorrhagicum, a rash on the soles of the feet or palms of the hands.
Diagnosing Reactive Arthritis
Diagnosing reactive arthritis involves a combination of medical history, physical examination, and laboratory tests. A doctor may:
- Review Symptoms: Discuss recent infections and any accompanying symptoms.
- Perform Blood Tests: To check for markers of inflammation and specific antibodies.
- Conduct Joint Aspiration: To analyze joint fluid and rule out other types of arthritis.
- Imaging Tests: Such as X-rays or MRI, to examine joint damage and inflammation.
Treatment Options for Reactive Arthritis
While there is no cure for reactive arthritis, treatment focuses on managing symptoms and controlling inflammation. Common treatments include:
Medications
- Nonsteroidal Anti-Inflammatory Drugs (NSAIDs): Such as ibuprofen or naproxen, to reduce pain and inflammation.
- Corticosteroids: Injections into the affected joint to quickly reduce severe inflammation.
- Disease-Modifying Antirheumatic Drugs (DMARDs): Such as sulfasalazine or methotrexate, for chronic or severe cases.
- Antibiotics: If an ongoing infection is identified.
Physical Therapy
Physical therapy can help maintain joint function and mobility. Exercises to strengthen the muscles around the affected joints can reduce stress on the joints and improve overall function.
Lifestyle Changes
- Rest and Activity Modification: Balancing rest with gentle exercise to prevent stiffness and maintain mobility.
- Healthy Diet: An anti-inflammatory diet rich in fruits, vegetables, and omega-3 fatty acids may help manage symptoms.
- Stress Management: Stress can exacerbate symptoms, so practices like yoga, meditation, and deep breathing exercises can be beneficial.
Living with Reactive Arthritis
Living with reactive arthritis can be challenging, but with the right approach, many people manage their symptoms effectively and lead fulfilling lives. It's essential to work closely with healthcare providers to develop a personalized treatment plan and make lifestyle adjustments that support overall health and well-being.
Support and Resources
Connecting with others who have reactive arthritis can provide valuable support and information. Organizations like the Arthritis Foundation offer resources, support groups, and information on the latest research and treatments.

Conclusion
Reactive arthritis is a condition that requires careful management and a proactive approach to treatment. By understanding its causes, recognizing the symptoms early, and working with healthcare professionals, individuals with reactive arthritis can manage their condition effectively and maintain a good quality of life. Stay informed, seek support, and take charge of your health.
