Insights

Assessing cord blood specific IgE (Immunoglobulin E) in newborns with a family history of allergies can help predict atopy. Elevated levels may indicate a higher risk of developing allergic symptoms.

Area of Science:

  • Immunology
  • Pediatrics
  • Allergy Research

Background:

  • Family history is a known risk factor for allergic diseases.
  • Early identification of atopy is crucial for timely intervention.

Purpose of the Study:

  • To determine a predictive threshold for specific IgE (Immunoglobulin E) in cord blood for atopy.
  • To assess the clinical utility of the Pharmacia CAP System for allergy diagnosis.

Main Methods:

  • Evaluated cord blood specific IgE levels in newborns with a first-degree relative affected by allergic disease.
  • Correlated specific IgE levels with clinical follow-up at 18 months for allergic symptoms.
  • Utilized the Pharmacia CAP System for specific IgE quantification.

Main Results:

  • Nine out of 60 newborns with a positive family history had specific IgE > 0.35 KU/L.
  • Seven of these nine children exhibited allergic symptoms at 18-month follow-up.
  • 65% of children with a positive history but no elevated specific IgE, and 100% with negative history and no elevated specific IgE, remained symptom-free.

Conclusions:

  • Cord blood specific IgE measurement, combined with family history, shows potential for early atopy diagnosis.
  • The Pharmacia CAP System demonstrated clinical reliability in this context.
  • Identifying high-risk infants can facilitate proactive allergy management.

Antibody Structure

Overview
Antibodies, also known as immunoglobulins (Ig), are essential players of the adaptive immune system. These antigen-binding proteins are produced by B cells and make up 20 percent of the total blood plasma by weight. In mammals, antibodies fall into five different classes, which each elicits a different biological response upon antigen binding.
The Y-Shaped Structure of Antibodies Consists of Four Polypeptide Chains
Antibodies consist of four polypeptide chains: two identical heavy...

Transcytosis of IgG01:15

Transcytosis of IgG

Transcytosis is the process in which molecules are internalized by endocytosis, transported across the cell, and released through exocytosis from the opposite end of the cell. Molecules such as insulin, immunoglobulins, and certain nutrients are transferred through the recycling endosomes by recycling and transcytosis.
IgG molecules from a mother undergo transcytosis starting around 13 weeks of gestation. The amount of IgG transferred and entering the fetal blood circulation increases with...
Special Features of Adaptive Immunity01:20

Special Features of Adaptive Immunity

The adaptive immune system, a crucial component of the overall immune response, offers a highly specialized defense against pathogens. It involves specific cell types and features, enabling it to combat infections effectively and efficiently.
The primary cell types involved in adaptive immunity are T cells and B cells. Each type has a unique role in defending the body against pathogens. T cells are responsible for cell-mediated immunity. They identify and eliminate infected cells directly,...
Development of Immunocompetence01:22

Development of Immunocompetence

The initiation of cell-mediated immunity can be observed as early as the third month of fetal growth, with active antibody-mediated immunity following approximately one month later.
The initial cells that migrate from the fetal thymus settle within the skin and epithelial tissues lining the mouth, digestive tract, and in females, the uterus and vagina. These cells, including skin-based dendritic cells, serve as antigen-presenting cells, playing a key role in T cell activation.
Subsequent T...
Hypersensitivities01:30

Hypersensitivities

Hypersensitivity, also known as a hypersensitivity reaction or allergic reaction, is a condition where the body's immune system reacts abnormally to a foreign substance. Such substances, that cause hypersensitivity are referred to as an allergen, could be something typically harmless to most people, like pollen or certain foods.
Types of Hypersensitivities
Hypersensitivity reactions are categorized into four types: Type 1, Type 2, Type 3, and Type 4. Each type has a distinct mechanism...
