Reactive arthritis triad

Last edited: 4/10/2026

Overview

Reactive arthritis is a form of inflammatory arthritis that can occur after an infection elsewhere in the body, typically in the gastrointestinal or genitourinary tract. It is characterized by a triad of symptoms: arthritis, urethritis, and conjunctivitis.

Diagnosis

  • The classic triad includes arthritis, urethritis, and conjunctivitis 1.
  • Arthritis typically affects the lower extremities and is asymmetric 1.
  • Urethritis may present as dysuria or discharge 1.
  • Conjunctivitis can cause redness and irritation 1.
  • Dermoscopy can aid in visualizing nail changes in related conditions like nail psoriasis, which can be associated with psoriatic arthritis 1.

    • Management

  • Management focuses on treating the underlying infection and managing symptoms.
  • Antibiotics may be used to treat the initial infection 1.
  • Nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly used for arthritis symptoms 1.
  • Other treatments may include disease-modifying antirheumatic drugs (DMARDs) or corticosteroids for more severe cases 1.

    • Special Populations

  • No specific information regarding special populations was provided in the abstracts.

    • Key Recommendations

  • Consider the classic triad of arthritis, urethritis, and conjunctivitis in the diagnosis of reactive arthritis 1.
  • Utilize NSAIDs for symptomatic relief of arthritis 1.
  • Treat the underlying infection with appropriate antibiotics 1.
