Abstract

Insights

This study highlights that combining medical and surgical treatments for Brucella endocarditis (BE) significantly reduces patient morbidity and mortality. Aggressive valve replacement with debridement, alongside long-term antibiotic therapy, is crucial for effective management of this infection.

Area of Science:

  • Infectious Diseases
  • Cardiology
  • Surgical Management

Background:

  • Brucellosis is endemic in the Mediterranean and Middle East, including Turkey.
  • Native endocarditis caused by Brucella species (Brucella endocarditis, BE) presents a significant clinical challenge.

Purpose of the Study:

  • To report the medical and surgical management outcomes for 31 patients diagnosed with native Brucella endocarditis.
  • To evaluate the effectiveness of combined therapeutic strategies in reducing morbidity and mortality associated with BE.

Main Methods:

  • Retrospective analysis of 31 patients with suspected Brucella endocarditis.
  • Diagnosis confirmed by Brucella species isolation or serological antibody presence.
  • Patients received preoperative antibiotic therapy, followed by valve replacement with extensive tissue debridement, and long-term antibiotic treatment. Follow-up included serological titers, blood cultures, and echocardiography.

Main Results:

  • All patients presented with fever and dyspnea (NYHA Class 3 or 4).
  • Aortic valve was most commonly affected (19 patients), followed by the mitral valve (7 patients) and both valves (5 patients).
  • Valve replacement with mechanical or biologic prostheses was performed. Post-treatment, all patients were afebrile at discharge, with a mean antibiotic duration of 101.2 ± 16.9 days and a follow-up of 37.1 ± 9.2 months.

Conclusions:

  • A combination of adequate medical and surgical therapy significantly decreased morbidity and mortality rates in native Brucella endocarditis.
  • Aggressive valve replacement with debridement, supported by efficient preoperative and long-term postoperative medical treatment, is the cornerstone of successful management.

Endocarditis I: Introduction

Introduction:Endocarditis is the infection of the endocardium, the inner lining of the heart and its valves. When the heart muscle is involved, the condition is termed myocarditis, while an infection of the outer lining is called pericarditis. Infective endocarditis (IE) primarily affects the endocardium, where pathogens adhere to the valves or lining, forming vegetation that can lead to severe complications. Infective endocarditis occurs when microorganisms, usually bacteria from other body...

Endocarditis II: Clinical Features of Infective Endocarditis

Endocarditis can present various clinical features depending on the causative organism and the patient's underlying health conditions. Initially, the clinical features of infective endocarditis develop gradually, presenting with nonspecific symptoms that can be easily mistaken for other illnesses.General SymptomsEarly symptoms of infective endocarditis are fever, chills, weakness, malaise, fatigue, and weight loss. These symptoms reflect the systemic nature of the infection and the body's...

Endocarditis III: Medical Management

Infective endocarditis management involves a multifaceted approach encompassing infection prevention, lifestyle modifications, pharmacological therapy, and surgical management.Infection Prevention:Hand Hygiene: Thorough handwashing is crucial to prevent the spread of infection. Hand hygiene should be performed regularly, especially before and after using the restroom.Oral Hygiene: Good oral hygiene is essential. It includes brushing teeth immediately after waking up and before bed, flossing...

Endocarditis IV: Nursing Management

Infective endocarditis (IE) is a chronic infection of the heart's endocardium, primarily affecting the heart valves. A detailed nursing assessment for a patient with IE involves collecting subjective and objective data to ensure an accurate diagnosis and timely intervention.Subjective DataThe nurse gathers information about the patient's symptoms and complaints during the subjective assessment. Patients with infective endocarditis often report non-specific symptoms that can mimic other...

Rheumatic Heart Disease I: Introduction

Rheumatic heart disease or RHD is a chronic condition that results from rheumatic fever, causing permanent damage to the heart valves.Etiology and Risk FactorsIt primarily arises from rheumatic fever, an inflammatory disease that can develop after untreated or inadequately treated group A streptococcal (GAS) pharyngitis. Streptococcus spreads through direct contact with oral or respiratory secretions. While the bacteria are the causative agents, factors like malnutrition, overcrowding, poor...

Mitral Stenosis III: Medical Management

Mitral stenosis, a condition marked by the narrowing of the mitral valve, necessitates an integrated approach for effective management. This approach includes preventative measures, medical therapy, and surgical interventions to reduce symptoms and prevent complications.PreventionPrevention of mitral stenosis primarily focuses on reducing the incidence of bacterial infections, particularly streptococcal infections, which can lead to rheumatic fever and subsequent valvular damage.
