Insights

Children with early childhood allergic rhinitis and wheezing face higher risks of internalizing disorders like anxiety and depression by age seven. Multiple allergic conditions amplify this risk in a dose-dependent manner.

Area of Science:

  • Pediatric Allergy and Immunology
  • Child and Adolescent Psychiatry
  • Developmental Psychology

Background:

  • The link between allergic diseases and internalizing disorders requires further investigation, especially concerning multiple conditions and longitudinal data.
  • Previous studies have not fully characterized the long-term association between early-life allergic diseases and later internalizing behaviors.

Purpose of the Study:

  • To investigate the association between multiple allergic diseases in early childhood and validated measures of internalizing disorders in school-aged children.
  • To examine the dose-dependent relationship between the number of allergic diseases and internalizing behaviors.

Main Methods:

  • Longitudinal study of 546 children from the Cincinnati Childhood Allergy and Air Pollution Study.
  • Assessment of allergic diseases (allergic rhinitis, persistent wheezing, atopic dermatitis, sensitization) at age 4.
  • Evaluation of internalizing disorders using the Behavior Assessment System for Children, Second Edition (BASC-2) at age 7, analyzed via logistic and linear regression.

Main Results:

  • Allergic rhinitis at age 4 was significantly linked to higher internalizing, anxiety, and depression scores at age 7.
  • Allergic persistent wheezing at age 4 was associated with elevated internalizing scores.
  • The presence of multiple allergic diseases at age 4 showed a dose-dependent association with increased internalizing scores.

Conclusions:

  • Early childhood allergic rhinitis and persistent wheezing increase the risk for internalizing behaviors in school-aged children.
  • A greater number of allergic diseases in early childhood is associated with a higher risk and severity of internalizing disorders.

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,...

Autism Spectrum Disorder

Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.

Allergic Drug Reactions01:27

Allergic Drug Reactions

Allergic reactions related to drugs are hypersensitivity responses driven by the immune system and bear no connection to the drug's therapeutic action. While drugs in isolation do not trigger an immune response, they can interact with endogenous proteins to form antigens. These antigens stimulate lymphocytes to produce antibodies. IgE-type antibodies attach themselves to mast cells. Upon subsequent exposure to the same stimulus, the antigen-antibody interaction is initiated, unleashing...

Attention-Deficit/Hyperactivity Disorder

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....

Causes of Social Behavior III: Biological and Environmental Influences

Social behavior is a complex phenomenon that arises from the interaction between biological predispositions and environmental influences. This intricate interplay shapes how individuals think, feel, and act in various social contexts. Understanding these mechanisms requires insights from psychology, neuroscience, genetics, and evolutionary theory.Environmental Influences on Social BehaviorEnvironmental factors, including temperature, odors, and visual stimuli, play a crucial role in shaping...
