[The current course and treatment of infectious endocarditis]
Abstract:
Clinical study of 172 patients treated in the Burdenko Military Hospital for subacute infectious endocarditis in 1980-1996 compared with 192 cases in 1950-1979. Contemporary course of the disease is attended by a few symptoms, primordiality and single-valve affection. On the grounds of antibiotics sensitivity of the most prevalent infection agents discovered in 1996, the article develops some schemes of antibacterial therapy for Streptococcus, Enterococcus and staphylococcal etiology of disease. Rational antibiotic therapy together with surgery measures reduced lethality to 14.3% for Streptococcus endocarditis, to 16.7%--for Enterococcus and to 34.4%--for Staphylococcus.
Insights
This study on subacute infectious endocarditis found that modern treatment, including targeted antibiotic therapy and surgery, significantly reduced mortality rates for Streptococcus, Enterococcus, and Staphylococcus infections.
Area of Science:
- Cardiology
- Infectious Diseases
- Medical Microbiology
Background:
- Subacute infectious endocarditis presents with fewer symptoms and primarily affects a single valve in contemporary cases.
- Historical data from 1950-1979 is compared with recent data from 1980-1996.
Purpose of the Study:
- To analyze changes in the clinical presentation of subacute infectious endocarditis over time.
- To develop effective antibacterial therapy schemes based on prevalent pathogen antibiotic sensitivity.
- To evaluate the impact of modern treatment strategies on endocarditis lethality.
Main Methods:
- Retrospective analysis of 172 patients treated between 1980-1996 and 192 patients from 1950-1979.
- Identification of prevalent causative agents (Streptococcus, Enterococcus, Staphylococcus) and assessment of their antibiotic sensitivity.
- Implementation and evaluation of targeted antibiotic regimens combined with surgical interventions.
Main Results:
- Contemporary endocarditis cases exhibit a less symptomatic and predominantly single-valve presentation.
- Antibiotic sensitivity testing guided the development of specific treatment protocols for major bacterial etiologies.
- Combined antibiotic and surgical therapy led to reduced lethality: 14.3% for Streptococcus, 16.7% for Enterococcus, and 34.4% for Staphylococcus endocarditis.
Conclusions:
- Modern therapeutic approaches, integrating rational antibiotic selection and surgical management, have improved outcomes in subacute infectious endocarditis.
- Tailored antibacterial strategies are crucial for managing Streptococcus, Enterococcus, and Staphylococcus endocarditis.
- The study highlights a shift in disease presentation and the effectiveness of contemporary treatment protocols.
