ReviewAcute rheumatic fever and streptococci: the quintessential pathogenic trigger of autoimmunity.
Acute rheumatic fever (ARF) is a non-suppurative complication of pharyngeal infection with group A streptococcus. Signs and symptoms of ARF develop 2 to 3 weeks following pharyngitis and include arthritis, carditis, chorea, subcutaneous nodules, and erythema marginatum. ⋯ ARF still represents one of the quintessential examples of a pathogenic trigger culminating in autoimmune manifestations. In this review, we will focus on the pathogenesis and etiology of ARF and its complications, along with diagnostic and treatment approaches to both ameliorate and prevent long-term sequelae of this potentially debilitating disease.
