Allergic Reactions: Anaphylaxis

142
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,...

Allergic Drug Reactions

1.6K
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...

Development of Immunocompetence

1.1K
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...

Inflammatory Bowel Disease III: Diagnostic Studies and Management I-Nutritional Therapy

1.0K
Various diagnostic tests are employed in the diagnostic process for Inflammatory Bowel Disease (IBD), particularly to differentiate between Crohn's disease and ulcerative colitis.
Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Drug Dosing: Infants and Children

713
Pediatric patient dosages diverge from adults due to disparities in body surface area, total body water, and extracellular fluid per kilogram of body weight. The dosing regimen considers the variations in pharmacokinetics and pharmacology across distinct age groups, encompassing preterm newborns, infants, young children, older children, and adolescents. Calculation of pediatric patient doses is predicated on determining body surface area, which exhibits a superior correlation with the child's...

    Area of Science:

    • Pediatric Nutrition
    • Allergy Management
    • Food Science

    Background:

    • Increasing prevalence of infant formulas for food allergy treatment and prevention.
    • Availability of various hydrolyzed and amino acid-based formulas.
    • Need for clarity on hypoallergenic claims in infant nutrition.

    Purpose of the Study:

    • To review the landscape of infant formulas for food allergy.
    • To differentiate between hypoallergenic and non-hypoallergenic options.
    • To guide appropriate selection of formulas for allergic infants.

    Main Methods:

    • Literature review of infant formula types and their properties.
    • Analysis of hypoallergenic criteria for infant formulas.
    • Evaluation of clinical evidence for formula efficacy and tolerance.

    Main Results:

    • Extensively hydrolyzed and amino acid-based formulas meet hypoallergenic criteria.
    • Partially hydrolyzed formulas, while not hypoallergenic, show some allergy prevention efficacy.
    • Soybean-derived formulas are often tolerated by infants with cow's milk allergy.
    • Probiotic/prebiotic effects in formulas remain inconsistent.
    • Misleading hypoallergenic marketing requires careful pediatrician attention.

    Conclusions:

    • A range of hypoallergenic formulas and milk substitutes exist for pediatricians.
    • Careful consideration is needed due to inaccurate hypoallergenic marketing.
    • Understanding formula composition is crucial for managing infant food allergies.
