Insights

Gram-negative endocarditis in children is rare, often caused by HACEK bacteria. This case highlights Cardiobacterium hominis endocarditis in a pediatric patient with congenital heart disease, successfully treated with antibiotics.

Area of Science:

  • Pediatric Cardiology
  • Infectious Diseases
  • Microbiology

Background:

  • Gram-negative endocarditis is uncommon in pediatric populations.
  • The HACEK group (Haemophilus species, Actinobacillus actinomycetemcomitans, Cardiobacterium hominis, Eikenella corrodens, Kingella kingae) are frequent causative agents.
  • Cardiobacterium hominis endocarditis is particularly rare in children, with limited reported cases.

Observation:

  • A 12-year-old boy with a history of Tetralogy of Fallot and pulmonary atresia presented with fatigue.
  • Echocardiography revealed a vegetation on his right ventricle to pulmonary artery conduit.
  • Blood cultures identified Cardiobacterium hominis as the causative pathogen.

Findings:

  • The patient received a 6-week course of appropriate antibiotic therapy.
  • Successful treatment of Cardiobacterium hominis endocarditis was achieved.
  • This case adds to the limited pediatric literature on HACEK endocarditis.

Implications:

  • Highlights the importance of considering HACEK organisms in pediatric endocarditis, especially in complex congenital heart disease.
  • Emphasizes the need for prompt diagnosis and appropriate antibiotic management.
  • Contributes to understanding the clinical presentation and treatment of rare pediatric infectious endocarditis.

Endocarditis I: Introduction01:25

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...

Myocarditis II: Clinical Features and Diagnostic Tests

Myocarditis is an inflammation of the heart muscle. The symptoms vary widely, encompassing asymptomatic presentations to severe, acute manifestations.Clinical PresentationAsymptomatic cases: In some instances, myocarditis may be asymptomatic, with the infection resolving without intervention. These cases often go undetected unless discovered incidentally through diagnostic imaging or tests conducted for other reasons.General Early Symptoms: Early symptoms of myocarditis are non-specific and can...

Cardiomyopathy III: Hypertrophic Cardiomyopathy

Hypertrophic cardiomyopathy, or HCM, is an autosomal dominant genetic disorder characterized by asymmetric left ventricular hypertrophy without ventricular dilation. It is more common in men and is typically diagnosed in young, athletic adults.EtiologyHCM is primarily genetic and is caused by mutations in genes encoding sarcomeric proteins. Researchers have identified over 1400 mutations across at least 11 different genes. Among these, the most frequently occurring mutations are found in the...
