Insights

CD36 deficiency is as common in children with heart disease as in healthy individuals. However, some children with CD36 deficiency may experience myocardial damage under certain conditions.

Area of Science:

  • Cardiology
  • Immunology
  • Genetics

Background:

  • The physiological role of CD36 molecule in pediatric heart disease remains under-investigated.
  • CD36 deficiency is a condition affecting platelet and monocyte function.

Purpose of the Study:

  • To investigate the prevalence and role of CD36 deficiency in pediatric heart disease.
  • To determine if CD36 deficiency is associated with specific types of heart conditions or increased susceptibility to myocardial damage.

Main Methods:

  • Flow cytometry was used to measure CD36 antigen expression in platelets and monocytes.
  • 189 pediatric patients with various heart diseases were analyzed.
  • CD36 deficiency was classified into Type I and Type II.

Main Results:

  • CD36 deficiency was identified in 7.9% of pediatric heart disease patients.
  • Prevalence varied across heart disease types: congenital heart disease (7.6%), myocardial disease (20.0%), Kawasaki disease (4.9%), and arrhythmia (6.7%).
  • Three patients with myocardial disease and CD36 deficiency experienced transient myocardial damage, potentially linked to fatty acid metabolism issues.

Conclusions:

  • The frequency of CD36 deficiency in childhood heart disease is similar to that in healthy populations.
  • CD36 deficiency may predispose individuals to myocardial damage under specific adverse conditions like infections or steroid therapy.

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...

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...

Cardiomyopathy II: Dilated Cardiomyopathy

Dilated cardiomyopathy, or DCM, is a progressive myocardial disorder characterized by ventricular chamber dilation and contractile dysfunction.EtiologyVarious factors can cause DCM, including hypertension and heavy alcohol intake, which contribute to the weakening and enlargement of the heart muscle. Viral infections, such as Coxsackievirus B, adenoviruses, and influenza, can lead to DCM by causing inflammation and damage to heart tissue. Certain chemotherapeutic agents, including daunorubicin,...

Cardiomyopathy IV: Restrictive Cardiomyopathy

Restrictive cardiomyopathy (RCM) is a rare heart muscle disease characterized by impaired ventricular filling due to stiffened ventricular walls, leading to significant diastolic dysfunction.EtiologyRestrictive cardiomyopathy can arise from both inherited and acquired diseases, many of which are systemic. It is categorized into four main types: infiltrative, storage, non-infiltrative, and endomyocardial diseases.Infiltrative diseases, such as amyloidosis, lead to RCM by depositing amyloid...

Rheumatic Heart Disease II: Clinical Manifestations and Diagnostic Studies

The key clinical manifestations of Rheumatic heart disease (RHD) include several distinct cardiac symptoms.Carditis, a hallmark of acute rheumatic fever, involves inflammation of the heart's endocardium, myocardium, and pericardium. Chronic RHD often results from recurrent episodes of carditis. Its symptoms include the following:Murmurs are caused by valvular damage, especially to the mitral and aortic valves. Mitral stenosis or regurgitation is common, with characteristic heart murmurs...
