[Clinical relationship between reactive arthritis and SARS-CoV-2 infection: A scoping review].

Introduction: Reactive arthritis (ReA) is a monoarthritis or oligoarthritis that mainly affects the extremities, it can be related to bacterial or viral infections. Currently, COVID-19 has been linked to the development of arthropathies due to its inflammatory component. Objectives: A scoping review of the literature that describes the clinical characteristics of ReA in survivors of SARS-CoV-2 infection. Materials and methods: A systematic review based on the guidelines for reporting systematic reviews adapted for Prisma-P exploratory reviews and steps proposed by Arksey and adjusted by Levan. Experimental and observational studies published in PubMed and Scopus, English and Spanish, which answered the research questions posed, were included. Results: Twenty-five documents were included describing the main clinical manifestations of ReA in 27 patients with a history of SARS-CoV-2 infection. The time from the onset of symptoms or microbiological diagnosis of COVID-19 to the development of articular and/or extra-articular manifestations compatible with ReA ranged from 7 days to 120 days. The clinical joint manifestations described were arthralgia and oedema, predominantly in knee, ankle, elbow, interphalangeal, metatarsophalangeal, and metacarpophalangeal joints. Conclusions: Arthralgias in the extremities are the main symptom of ReA in patients with a history of COVID-19, whose symptoms can present in a period of days to weeks from the onset of clinical symptoms or microbiological diagnosis of SARS-CoV-2 infection.
