Overview
Acute streptococcal pericarditis is an inflammatory condition of the pericardium caused by Streptococcus species, often presenting with chest pain, pericardial friction rub, and characteristic electrocardiographic changes. 1Diagnosis
ECG findings: P-R segment depression can be an early diagnostic feature 1.
Clinical signs: Presence of pericardial friction rub is highly indicative 1.
Laboratory tests: Elevated inflammatory markers (e.g., CRP, ESR) are common but not specific 1.
Echocardiography: Essential for ruling out tamponade and assessing pericardial effusion 1.Management
Antibiotics: First-line treatment with penicillin or a first-generation cephalosporin, typically 10-14 days 1.
Nonsteroidal anti-inflammatory drugs (NSAIDs): Used for pain relief and to reduce inflammation 1.
Colchicine: Adjunctive therapy to reduce recurrence rates, typically 2 mg twice daily for 10 days 1.
Steroids: Considered in refractory cases or when NSAIDs are contraindicated 1.Special Populations
Pregnancy: Management focuses on safe antibiotic choices like penicillin; NSAIDs should be avoided 1.
Pediatrics: Similar principles apply, with careful monitoring for complications and adherence to age-appropriate dosing 1.
Elderly: Increased vigilance for complications such as cardiac tamponade; tailored antibiotic therapy based on comorbidities 1.
Comorbidities: Adjust antibiotic choice based on patient-specific conditions (e.g., renal impairment) 1.Key Recommendations
Recognize P-R segment depression on ECG as an early sign of acute pericarditis (Evidence: Moderate) 1
Initiate empirical antibiotic therapy with penicillin or a first-generation cephalosporin for 10-14 days (Evidence: Moderate) 1
Use NSAIDs for symptomatic relief and consider colchicine to reduce recurrence risk (Evidence: Moderate) 1References
