Insights

Oxidative stress markers correlate with allergic indices in children, influencing allergic responses and atopic disease risk. Specific markers link to allergic rhinitis and asthma development.

Area of Science:

  • Immunology
  • Environmental Health
  • Pediatrics

Background:

  • The link between oxidative stress and atopic diseases remains unclear.
  • Existing research identifies risk factors for atopic diseases but lacks comprehensive analysis of oxidative stress markers and atopic indices.

Purpose of the Study:

  • To investigate the association between oxidative stress markers and atopic indices in a pediatric birth cohort.
  • To explore the relationship between oxidative stress, allergic sensitization, and the risk of developing atopic diseases.

Main Methods:

  • A 7-year follow-up of 132 children from a birth cohort.
  • Measurement of oxidative stress markers: plasma glutathione peroxidase (GPx), myeloperoxidase (MPO), total antioxidant capacity (TAC), and urine 8-hydroxy-2'-deoxyguanosine (8-OHdG).
  • Assessment of allergic indices: allergen-specific IgE, fractional exhaled nitric oxide (FeNO), and pulmonary function tests.

Main Results:

  • GPx and MPO levels showed inverse correlations with food (shrimp, crab) and house dust mite sensitization, respectively.
  • 8-OHdG levels were negatively correlated with FeNO levels (p < 0.01).
  • TAC levels positively correlated with FVC and FEV1 predicted values (p < 0.05).
  • While not directly associated with atopic disease risk, specific marker-sensitization/index pairs were linked to increased risk of allergic rhinitis (GPx-crab, 8-OHdG-FeNO) and asthma (MPO-mite, TAC-pulmonary function).

Conclusions:

  • Oxidative stress markers are significantly correlated with various allergic indices.
  • These correlations suggest a role for oxidative stress in modulating allergic responses and contributing to the development of atopic diseases.

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...

Asthma: Pathogenesis and Management

Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.

Psychoneuroimmunology: Cardiovascular Disease

Psychoneuroimmunology (PNI) is a multidisciplinary field that examines how psychological factors, particularly stress, interact with the immune system and impact physical health. Research in PNI has shown that chronic or traumatic stress can disrupt both the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system. These disruptions contribute to serious health conditions, including cardiovascular diseases.
A key area of focus in PNI is the relationship between stress and coronary...
