Concomitant Acute Rheumatic Fever and Acute Post Streptococcal Glomerulonephritis

Acute rheumatic fever (RF) and acute post Streptococcal glomerulonephritis (APSGN) are non-suppurative complications of a Group A Streptococcus (GAS) infection. The concomitant incidence of both complications in a patient is rare because nephritogenic and rheumatogenic strains belong to different serotypes of Group A beta-hemolytic Streptococcus (GABHS). We present a case of a 47-year-old female who had concomitant acute RF and APSGN from a Streptococcus pyogenes infection. It is important to have a high clinical suspicion for the sequela of GABHS infection in the setting of cardiac and renal disease following upper respiratory infection (URI) symptoms even in adults and in geographic locations with the nearly undetectable burden of acute RF because of the importance of secondary prophylaxis with an antibiotic.
