Key Concepts

Streptococcal Pharyngitis

This is an acute infection of the throat and tonsils caused primarily by group A Streptococcus bacteria. It is a common cause of sore throat and can lead to several post-infection complications due to the immune response triggered by the bacteria.

Post-Streptococcal Immunological Complications

After a streptococcal infection, the body’s immune response may mistakenly target its own tissues, leading to complications. These immune-mediated sequelae include conditions such as acute rheumatic fever and post-streptococcal glomerulonephritis, which manifest in different organ systems.

Acute Rheumatic Fever

This is a serious inflammatory disease that can develop after an untreated or inadequately treated streptococcal infection. It primarily affects the heart, joints, skin, and brain, and is characterized by a combination of symptoms including carditis, migratory polyarthritis, and other systemic signs.

Post-Streptococcal Glomerulonephritis

This complication refers to an immune-mediated inflammation of the glomeruli in the kidneys that can occur following a streptococcal infection, leading to symptoms such as hematuria, edema, and hypertension.

Scarlet Fever

Scarlet fever is a condition that typically follows streptococcal pharyngitis and is identified by a characteristic red rash, high fever, and a ‘strawberry’ tongue. It is caused by the toxin-producing strains of group A Streptococcus.

Reye's Syndrome

Reye's syndrome is a rare but serious condition involving acute encephalopathy and liver dysfunction, most commonly linked to aspirin use in children suffering from viral infections such as influenza or chickenpox. It is not associated with streptococcal infections.
