-Curative and preventive antibiotic therapy in infective endocarditis-

Area of Science:

• Cardiology
• Infectious Diseases
• Microbiology

Background:

• Infective endocarditis (IE) is a serious infection affecting heart valves and internal cardiac structures.
• Diagnosis commonly utilizes Durack's criteria, incorporating echocardiographic findings.
• Streptococci and staphylococci are the predominant causative microorganisms.

Purpose of the Study:

• To outline the diagnostic standards, therapeutic strategies, and prophylactic measures for infective endocarditis.
• To highlight challenges in diagnosing IE, particularly with negative blood cultures.
• To emphasize the role of surgery and prophylaxis in managing IE.

Main Methods:

• Review of established diagnostic criteria (Durack's criteria) for IE.
• Analysis of common etiological agents and their antibiotic sensitivities.
• Evaluation of treatment protocols including antibiotics, source eradication, and surgical intervention.
• Assessment of IE prophylaxis guidelines for at-risk populations.

Main Results:

• Durack's criteria, including echocardiography, are the standard for IE diagnosis.
• Parenteral bactericidal antibiotics and source eradication are key therapeutic principles.
• Special techniques are needed for IE diagnosis with negative blood cultures.
• Prosthetic valve IE often results from nosocomial bacteremia, frequently requiring surgery.
• IE prophylaxis is recommended for at-risk patients and often supersedes surgical antibiotic prophylaxis.

Conclusions:

• Effective IE management requires adherence to diagnostic standards and tailored therapeutic approaches.
• Early diagnosis and intervention, including surgery when indicated, are crucial for improving outcomes.
• Prophylaxis plays a vital role in preventing IE in susceptible individuals, especially those with prosthetic valves.
