Severe Pharyngodynia Followed by Migratory Polyarthritis and High Fever in Young Immigrants: Remember That Rheumatic Fever Is Still Relevant in 2020!

Abstract

Acute rheumatic fever (ARF) is the immune-mediated sequelae of untreated group-A streptococcal infection. In this regard, rheumatic heart disease is the most prominent manifestation with devastating long-term complications. In the postantibiotic era, ARF is extremely rare in high-income countries; thus, its diagnosis might escape the clinicians’ notice. However, its incidence remains high not only in certain low- and middle-income regions with poor public health systems but also in socioeconomically vulnerable populations residing in high-income countries. Herein, we report two cases of ARF in young immigrant adults in order to highlight the need for increased clinical suspicion to establish a prompt and timely diagnosis of ARF and describe in detail its differential diagnosis and approach to treatment.
