Summary
Atopic dermatitis in infants often leads to other allergies. Early management should address skin issues and prevent future respiratory allergies like asthma.
Area of Science:
- Dermatology
- Allergology
- Pediatrics
Context:
- Atopic dermatitis (AD) is a common inflammatory skin condition appearing in infancy.
- AD is linked to elevated serum IgE and food allergen sensitization.
- Skin colonization by Staphylococcus aureus can worsen AD lesions.
Purpose:
- To highlight the link between early-life atopic dermatitis and subsequent allergic diseases.
- To emphasize the need for comprehensive management beyond skin treatment.
Summary:
- Atopic dermatitis often manifests in the first year of life and is associated with elevated IgE and food sensitivities.
- While some foods can trigger flare-ups, their role requires clinical evaluation before dietary exclusion.
- Staphylococcus aureus colonization can exacerbate AD and necessitates topical antibiotic treatment.
- Children with AD are at increased risk for allergies, particularly respiratory conditions like asthma, especially with early egg sensitization.
Impact:
- Informs clinical practice regarding the holistic care of children with atopic dermatitis.
- Underscores the importance of early intervention to mitigate the risk of developing asthma and other allergic respiratory diseases.
- Highlights the connection between early-life atopic dermatitis, food sensitization, and the development of allergic asthma later in life.

Overview
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.

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...

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...
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: 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...
