High prevalence of allergy in North Cypriot children

Insights

Asthma and allergy prevalence is extremely high in North Cyprus children aged 7-12. House dust mite sensitization is a significant risk factor for developing childhood asthma.

Area of Science:

  • Pediatric Allergy and Immunology
  • Epidemiology of Respiratory Diseases
  • Childhood Asthma Research

Background:

  • The International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire has been a global standard for asthma prevalence research since 1991.
  • Standardized tools are crucial for comparing asthma and allergy data across diverse populations.

Purpose of the Study:

  • To evaluate the prevalence of asthma, allergic diseases, and atopy in schoolchildren in North Cyprus.
  • To establish baseline data for pediatric allergic conditions in the region.

Main Methods:

  • Utilized the ISAAC questionnaire for data collection from parents of 580 schoolchildren (ages 7-12) in Nicosia.
  • A subgroup of 97 children underwent skin prick testing (SPT) and lung function testing (LFT) for detailed allergic assessment.

Main Results:

  • Identified high prevalence rates: 20.8% for asthma ever, 10% for current wheezing, and 68% for SPT-positivity.
  • Atopy was significantly more prevalent in the tested subgroup, with house dust mite (HDM) identified as the most common sensitizing allergen.

Conclusions:

  • North Cyprus exhibits exceptionally high rates of asthma, allergic diseases, and atopic sensitization among children aged 7-12.
  • HDM sensitization emerges as a key risk factor contributing to the development of asthma in this pediatric population.

Allergic Reactions: Anaphylaxis

Anaphylaxis is a severe, life-threatening hypersensitivity reaction mediated by Immunoglobulin E (IgE) antibodies. When IgE binds to allergens, it triggers the release of mediators– histamine, leukotrienes, and prostaglandins from mast cells and basophils. These mediators cause vasodilation, edema, and inflammation, leading to various symptoms.The primary allergens causing anaphylaxis include food items (e.g., peanuts, shellfish), drugs (e.g., penicillin, asparaginase, corticotropin, heparin),...
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...

Cystic Fibrosis: Pathogenesis

Cystic fibrosis (CF), an autosomal recessive disorder, significantly affects the function of exocrine glands. This genetically inherited disease is characterized by the production of thick and sticky mucus, which can severely affect various organs and systems in the body.
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation, but...
Asthma-I: Introduction01:29

Asthma-I: Introduction

Asthma is a chronic respiratory ailment that requires careful management due to its varying symptoms and influencing factors. It is characterized by airway inflammation, bronchial hyperresponsiveness, and reversible airflow obstruction, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. The symptom frequency and intensity may vary considerably over time. It is also linked to immune system responses to allergens and irritants, highlighting the complex...
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...
