Acute rheumatic fever and streptococci: the quintessential pathogenic trigger of autoimmunity

Area of Science:

• Rheumatology
• Infectious Diseases
• Immunology

Background:

• Acute rheumatic fever (ARF) is a non-suppurative sequela of group A Streptococcus pharyngeal infection.
• Manifestations include arthritis, carditis, chorea, subcutaneous nodules, and erythema marginatum, typically appearing 2-3 weeks post-infection.
• ARF and rheumatic heart disease affect millions globally, posing a significant cause of cardiovascular mortality in younger adults.

Purpose of the Study:

• To review the pathogenesis and etiology of ARF and its complications.
• To discuss diagnostic strategies for ARF.
• To outline treatment approaches for ameliorating ARF and preventing long-term sequelae.

Main Methods:

• This is a review article.
• Literature search on pathogenesis, etiology, diagnosis, and treatment of ARF.
• Synthesis of current knowledge on ARF and rheumatic heart disease.

Main Results:

• ARF serves as a model for pathogen-triggered autoimmune diseases.
• Early diagnosis and treatment are crucial for preventing cardiac damage.
• Effective management strategies are essential to reduce long-term morbidity and mortality.

Conclusions:

• ARF remains a significant global health concern, particularly in developing regions.
• Understanding the autoimmune basis of ARF is key to developing targeted therapies.
• Comprehensive management, including secondary prophylaxis, is vital to prevent recurrent episodes and rheumatic heart disease progression.
