RESUMEN
Reactive arthritis is an aseptic inflammatory arthritis that is associated with intestinal, urogenital, and nasopharyngeal infections, and represents a systemic clinical presentation of these infections. Reactive arthritis among children still remains an issue in pediatric rheumatology. The variety of the clinical manifestations makes it difficult to diagnose and detect reactive arthritis. Moreover, there is a risk that reactive arthritis without a proper treatment can lead to chronic destructive joint diseases. As the articles' analysis has shown, this topic in pediatrics has been neglected over the past 10 years. Thus, the paper presents data on the epidemiology, pathophysiology, clinical presentation and diagnosis of this disease, as well as recommendations for further studies.
