Short-term therapy for streptococcal infective endocarditis. Combined intramuscular administration of penicillin and
Abstract:
In a prospective study, 91 patients with penicillin-sensitive infective endocarditis (IE) were treated for two weeks with intramuscular (IM) penicillin G procaine, 1.2 million units every six hours, plus streptomycin sulfate, 500 mg IM every 12 hours. Viridans streptococci were isolated from 70 patients (77%); 21 patients (23%) had Streptococcus bovis infections. Eighteen patients (20%) had had symptoms of IE for three months or longer. Follow-up ranged from two months to 6.6 years. There were no relapses; mild vestibular toxic reactions occurred in two patients (2%). Two patients (2%) died--one of sudden-onset severe heart failure and one of cardiac arrest after aortic valve replacement. Twenty-six patients (19%) required cardiac valve replacement after completion of antimicrobial therapy. This therapy seems as efficacious as four weeks of parenteral antimicrobial therapy and is more cost-effective.
Insights
Two weeks of penicillin G procaine and streptomycin sulfate effectively treated infective endocarditis (IE). This shorter regimen proved as efficacious as longer treatments, offering a more cost-effective approach for patients with IE.
Area of Science:
- Infectious Diseases
- Cardiology
- Pharmacology
Background:
- Infective endocarditis (IE) is a serious infection.
- Traditional treatment often involves prolonged antimicrobial therapy.
- Optimizing treatment duration and cost-effectiveness is crucial.
Purpose of the Study:
- To evaluate the efficacy and safety of a two-week intramuscular treatment regimen for penicillin-sensitive infective endocarditis.
- To compare this shorter regimen with traditional four-week parenteral antimicrobial therapy.
Main Methods:
- Prospective study of 91 patients with penicillin-sensitive IE.
- Treatment involved intramuscular penicillin G procaine and streptomycin sulfate for two weeks.
- Follow-up ranged from two months to 6.6 years.
Main Results:
- No relapses were observed in patients treated with the two-week regimen.
- Mild vestibular toxicity occurred in 2% of patients.
- 2% of patients died from IE complications; 19% required valve replacement post-therapy.
Conclusions:
- A two-week course of intramuscular penicillin G procaine and streptomycin sulfate is an efficacious and cost-effective treatment for infective endocarditis.
- This regimen demonstrates comparable efficacy to four-week parenteral therapies.
- The shorter duration offers potential benefits in terms of patient compliance and healthcare costs.
