Structured summary
|Updated
Among people with sore throat (pharyngitis), penicillin treatment probably reduces rheumatic fever recurrences and streptococcal throat infections (moderate certainty of evidence). No studies reported the effects of penicillin treatment on rheumatic heart disease progression, disability, mortality or adverse events among people with sore throat.

Background
Acute pharyngitis is hallmarked by acute onset of sore throat; the absence of cough, nasal congestion and discharge suggests a bacterial aetiology. Rapid antigen detection tests allow immediate point-of-care assessment of group A Streptococcus (GAS) pharyngitis. The goal of treatment of GAS is to prevent acute rheumatic fever, reduce the severity and duration of symptoms, and prevent transmission. Acute pharyngitis is generally a self-limited condition with resolution within two weeks. Infected individuals are not, however, immune to reinfection with most aetiological pathogens (BMJ Best Practice (accessed Dec 18 2020)).
Acute rheumatic fever is an autoimmune disease that may occur following group A streptococcal throat infection. It can affect multiple systems, including the joints, heart, brain, and skin. Only the effects on the heart can lead to permanent illness; chronic changes to the heart valves are referred to as chronic rheumatic heart disease. No treatment has been shown to alter the progression of acute rheumatic fever to chronic rheumatic heart disease. Secondary prophylaxis can improve the prognosis of established rheumatic valvular disease. The recommended choice of treatment is long-term penicillin secondary prophylaxis (BMJ Best Practice (accessed Nov 20 2020))
