Abstract:


Introduction: Post-Streptococcal Reactive Arthritis (PSRA) is defined as inflammatory arthritis of ≥1 joint associated with a recent group A streptococcal infection in a patient who does not fulfill the Jones criteria for the diagnosis of Acute Rheumatic Fever (ARF).

Methods: In this narrative review, we conducted a systematic search on MEDLINE, EMBASE, Cochrane Library and Google Scholar using the words poststreptococcal reactive arthritis. The search covered the time period between 1982 and 2016. The purpose of this review is to summarize the current state of knowledge of PSRA with respect to the definition, epidemiology, clinical presentation and treatment. We also summarize the key differences between PSRA, reactive arthritis (ReA) and ARF.

Results: PSRA has a bimodal age distribution at ages 8-14 and 21-37 years with an almost equal male to female ratio. Clinically, it causes acute asymmetrical non-migratory polyarthritis, however, tenosynovitis and small joint arthritis may occur. This disease entity can be associated with extraarticular manifestations, including erythema nodosum, uveitis and glomerulonephritis. The frequency of HLA-B27 in PSRA does not differ from that of the normal population, which suggests that it is a separate entity from ReA. Involvement of the axial skeleton, including sacroiliitis, is uncommon in PSRA. PSRA tends to occur within 10 days of a group A streptococcal infection, as opposed to the 2 to 3 weeks delay for ARF. PSRA can be associated with prolonged or recurrent arthritis, in contrast to ARF, in which arthritis usually lasts a few days to 3 weeks. Treatment usually involves NSAIDs or corticosteroids.

Conclusion: We summarize clinical features that help differentiate PSRA from ARF and ReA. First-line treatment options include NSAIDs and corticosteroids. Most cases resolve spontaneously within a few weeks, but some cases are recurrent or prolonged. There are no published randomized controlled trials of PSRA.
