Insights

Children with atopic eczema under 9 years old show a poor antibody response to Pneumococcal vaccination. This suggests a potential delay in immune system maturation for these young patients.

Area of Science:

  • Immunology
  • Pediatrics
  • Dermatology

Background:

  • Atopic eczema is a common condition in children.
  • Antibody response to vaccines is crucial for preventing infections.
  • Previous observations suggested impaired immunity in children with atopic eczema.

Purpose of the Study:

  • To investigate the antibody response to Pneumococcal vaccination in children under 9 with atopic eczema.
  • To compare this response with a control group of children with recurrent respiratory infections.
  • To identify potential immune system maturation delays.

Main Methods:

  • Retrospective study of 35 children with moderate to severe atopic eczema (ages 3-16).
  • Comparison with 36 control children (ages 3-16) with recurrent upper respiratory tract infections.
  • Analysis of Pneumococcal antibody responses after Pneumovax II immunization.

Main Results:

  • Only 17% of children with atopic eczema (ages 3-8) responded to Pneumovax, significantly lower than controls (57%).
  • No significant differences in total IgG2 levels were found between groups.
  • A delayed maturation of antibody response to Pneumococcus was observed in children with atopic eczema.

Conclusions:

  • Children with atopic eczema under 9 years exhibit a poorer antibody response to Pneumococcal vaccination.
  • This impaired response may indicate a delay in immune system maturation.
  • Further research is needed to understand the implications for infection susceptibility.

Immunological Memory01:23

Immunological Memory

Immunological memory, a pivotal pillar of the adaptive immune system, is responsible for the body's ability to remember and respond more swiftly and effectively to previously encountered pathogens. This remarkable feature is what makes vaccines so effective in preventing diseases.
What is Immunological Memory?
Immunological memory is an integral function of the immune system that allows it to recognize and react more rapidly and effectively to pathogens previously encountered. This feature is...
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...
Hypersensitivity Reactions: Delayed Hypersensitivity Reactions01:29

Hypersensitivity Reactions: Delayed Hypersensitivity Reactions

Delayed-Type Hypersensitivity (DTH), or Type IV hypersensitivity, is a cell-mediated immune response. It occurs when T cells, rather than antibodies, mediate a reaction to specific antigens. It is characterized by a delayed onset (1-2 days) and involves the recruitment of macrophages to the inflammation site.The initiation of a DTH response begins with the sensitization of T cells. During this phase, which lasts at least 1-2 weeks, antigen-specific T cells are activated, clonally expanded, and...
Atypical Pneumonia01:14

Atypical Pneumonia

Atypical pneumonia, often caused by Mycoplasma pneumoniae, is a form of pulmonary infection that differs from the classical presentation of bacterial pneumonia in both its cause and clinical symptoms. Mycoplasma pneumoniae is a pleomorphic bacterium notable for its lack of a rigid cell wall. This structural characteristic imparts resistance to beta-lactam antibiotics and significantly influences the bacterium’s behavior within the human host.Other pathogens responsible for the disease include...
Asthma I: Introduction01:28

Asthma I: Introduction

Asthma is a chronic inflammatory disorder of the airways characterized by variable airflow obstruction and heightened bronchial responsiveness to a wide range of triggers. The underlying inflammation leads to airway swelling, mucus hypersecretion, and smooth muscle constriction, all of which narrow the airway lumen and impede airflow. Clinically, asthma presents with recurrent episodes of wheezing, shortness of breath, chest tightness, and coughing, symptoms that typically vary in intensity and...
