Overview
Acute rheumatic fever (ARF) is an inflammatory disease triggered by an autoimmune response following infection with group A Streptococcus, typically manifesting as carditis, polyarthritis, chorea, erythema marginatum, and subcutaneous nodules 13.Diagnosis
Major Criteria: Carditis, polyarthritis, chorea, erythema marginatum, subcutaneous nodules 1.
Minor Criteria: Fever, arthralgia, elevated erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), and throat or skin evidence of recent streptococcal infection 1.
Serological Testing: Elevated serum IgG and total immunoglobulin (Ig) titers to extracellular antigens of Streptococcus pyogenes are indicative but not diagnostic 2.
Grading: Based on the presence of major and minor criteria, with a weighted score for diagnosis 1.Management
Antibiotics: Penicillin or erythromycin for streptococcal eradication 1.
Anti-inflammatory Therapy: Aspirin or other nonsteroidal anti-inflammatory drugs (NSAIDs) for symptom control 1.
Secondary Prophylaxis: Penicillin V or amoxicillin daily to prevent recurrence 1.Special Populations
Pediatrics: Commonly affected; diagnosis and management follow standard protocols 13.
Comorbidities: No specific adjustments mentioned for comorbidities; standard ARF management applies 1.Key Recommendations
Use the Jones criteria for diagnosing acute rheumatic fever, incorporating both major and minor clinical and laboratory findings (Evidence: Strong 1).
Monitor and treat elevated inflammatory markers like ESR and CRP alongside clinical symptoms (Evidence: Moderate 1).
Initiate secondary prophylaxis with penicillin or amoxicillin post-ARF to prevent recurrence (Evidence: Strong 1).References
