Allergic Drug Reactions

1.3K
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...

Skin Diseases and Disorders

5.1K
Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.
Gram-positive Staphylococcus spp. and Streptococcus spp. are responsible for many of the most common skin infections. However, many...

Hypersensitivities01:30

Hypersensitivities

7.2K
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...

Reticular Dermis01:15

Reticular Dermis

4.4K
The papillary and reticular dermis are the two layers of the dermis. They are made of connective tissue with fibers of collagen extending from one to the other, making the border between the two somewhat indistinct. The dermal papillae extending into the epidermis belong to the papillary layer, whereas the dense collagen fiber bundles below belong to the reticular layer.
Reticular Layer
Underlying the papillary layer is the much thicker reticular layer, composed of dense, irregular connective...

Summary

Pediatricians should recognize diverse skin reactions as potential signs of food allergy in children. Prompt referral to allergy specialists is crucial for accurate diagnosis and management of these food-related cutaneous conditions.

Area of Science:

  • Pediatric Dermatology
  • Allergology
  • Immunology

Background:

  • Cutaneous reactions are common manifestations of food allergy in children.
  • Various immune and non-immune mechanisms underlie these skin reactions.
  • Accurate identification is essential for appropriate patient care.

Purpose of the Study:

  • To highlight the spectrum of food-induced skin reactions in pediatric populations.
  • To emphasize the importance of recognizing these reactions in clinical practice.
  • To advocate for timely specialist referral for diagnosis.

Main Methods:

  • Review of reported cutaneous reactions associated with food allergy.
  • Categorization of reactions based on immunological mechanisms (IgE-mediated, cell-mediated, mixed, non-immune).

  • Clinical presentation examples including urticaria, angioedema, atopic dermatitis, and contact dermatitis.

    • Main Results:

    • Identified IgE-mediated reactions: urticaria, angioedema, flushing, pruritus.
    • Identified cell-mediated reactions: contact dermatitis, dermatitis herpetiformis.
    • Identified mixed and non-immune reactions: atopic dermatitis, irritant contact dermatitis, Frey's syndrome.

    Conclusions:

    • A wide array of skin conditions can be linked to food allergies in children.
    • Pediatricians must be vigilant in identifying potential food-related dermatoses.
    • Specialist evaluation is critical for definitive diagnosis and management of pediatric food allergy.
