Overview
Effective measures for the primary prevention of mitral stenosis include preventing of endocarditis and decreasing new patients of rheumatic fever. Effective measures for the primary prevention of rheumatic fever include reducing exposure to Group A beta-hemolytic streptococci and antibiotic prophylaxis for streptococcal pharyngitis. Intramuscular benzathine penicillin G and oral penicillin V are the recommended antibiotics in treatment of group A streptococcal infection in absence of penicillin allergy.
Primary Prevention
Effective measures for the primary prevention of mitral stenosis include preventing of endocarditis and decreasing new patients of rheumatic fever. Effective measures for the primary prevention of rheumatic fever include reducing exposure to Group A beta-hemolytic streptococci, which requires dramatic improvements in housing, hygiene infrastructure and access to health care for individuals in the developing countries. Most streptococcal pharyngitis, when treated with appropriate antibiotics, prevents acute rheumatic fever. Unfortunately, at least one third of episodes of acute rheumatic fever result from unapparent streptococcal infections. In addition, some symptomatic patients do not seek medical care; in these instances, rheumatic fever is not preventable.[1][2][3][4]
Antimicrobial Regimens
- Primary prevention of rheumatic fever via antimicrobial regimens:[5]
- Preferred regimen (1): Penicillin V 500 mg PO q6-8h for 10 days
- Preferred regimen (2): Amoxicillin 50 mg/kg PO qd for 10 days (maximum dose 1 g)
- Preferred regimen (3): Penicillin G 0.6 MU IM single dose (≤27 kg / ≤60 lb); 1.2 MU IM single dose (>27 kg / >60 lb)
- Alternative regimen (1): Cephalexin 500 mg PO bid for 10 days
- Alternative regimen (2): Cefadroxil 1 g PO qd for 10 days
- Alternative regimen (3): Clindamycin 20 mg/kg/day PO tid for 10 days (maximum dose 1.8 g/day)
- Alternative regimen (4): Azithromycin 12 mg/kg PO qd for 5 days (maximum dose 500 mg/day)
- Alternative regimen (5): Clarithromycin 15 mg/kg/day PO bid for 10 days (maximum 500 mg/day)
