Drug Toxicity: Allergic Reactions01:30

Drug Toxicity: Allergic Reactions

Drug-related allergies are immune-mediated responses triggered by the administration of pharmacological agents. These hypersensitivity reactions are classified based on the immune mechanisms involved. The four primary types—Type I, II, III, and IV—are mediated by different immunological pathways and exhibit distinct clinical manifestations.Type I Hypersensitivity/ IgE-Mediated Reactions: Immunoglobulin E (IgE) immediately mediates Type I hypersensitivity reactions. Upon initial exposure to a...
Anionic Chain-Growth Polymerization: Overview01:20

Anionic Chain-Growth Polymerization: Overview

The polymerization process that involves carbanion as an intermediate is called anionic polymerization. It is also a type of addition or chain-growth polymerization. Anionic polymerization gets initiated by a strong nucleophile such as an organolithium or a Grignard reagent. The most commonly used initiator for anionic polymerization is butyl lithium. Monomers involved in anionic polymerization must possess a vinyl group bonded to one or two electron-withdrawing groups. For instance,...
Acetals and Thioacetals as Protecting Groups for Aldehydes and Ketones01:24

Acetals and Thioacetals as Protecting Groups for Aldehydes and Ketones

Acetals are formed by reacting two equivalents of alcohol with carbonyl compounds like aldehydes or ketones. Acetals are unaffected by bases, nucleophiles, oxidizing agents, and reducing agents. They serve as protecting groups for aldehydes and ketones. Acetals can be easily formed and also easily removed via mild acid hydrolysis.
In the presence of multiple functional groups, when selective reduction of one group over the other is desired, groups like aldehydes and ketones that form acetals...
Hypersensitivity Reactions: Immune-Complex Reactions01:19

Hypersensitivity Reactions: Immune-Complex Reactions

Type III hypersensitivity reactions occur when antigen–antibody complexes form and activate the complement system. Normally, these complexes help the clearance of antigens by phagocytes and red blood cells. However, when large numbers of immune complexes are present, they can deposit in tissues—particularly in the walls of blood vessels—leading to inflammation and tissue injury. These deposits trigger complement activation and neutrophil recruitment, resulting in serum sickness, a systemic...
Staphylococcal Skin Infections01:29

Staphylococcal Skin Infections

Staphylococcus aureus is a Gram-positive coccus that resides harmlessly on the skin and mucous membranes of healthy individuals. When the skin barrier is breached, it can shift from a commensal to an opportunistic pathogen. This transition is facilitated by surface adhesins, such as clumping factor B and S. aureus surface protein G (SasG), which bind to structural proteins, including loricrin and cytokeratin, in the damaged epidermis. Protein A, another key factor, binds the Fc region of...
Allergic Reactions: Anaphylaxis01:30

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),...

Area of Science:

  • Dermatology
  • Toxicology
  • Polymer Science

Background:

  • Acrylates are versatile plastic materials derived from acrylic or methacrylic acid.
  • They are widely used in industrial, medical, dental, and consumer products, including paints, adhesives, and artificial nails.
  • Since the 1950s, allergic contact dermatitis to (meth)acrylate monomers has been frequently reported in occupational and non-occupational settings.

Purpose of the Study:

  • To review the literature on allergic contact dermatitis caused by (meth)acrylate monomers.
  • To discuss the irritant properties and sensitization potential of these chemicals.
  • To explore the phenomenon of multiple positive patch tests in acrylate-allergic patients and potential causes like cross-reactions or undisclosed impurities.

Main Methods:

  • Literature review of published reports on (meth)acrylate allergy.
  • Discussion of clinical observations and patch testing results.
  • Analysis of the chemical properties of (meth)acrylates relevant to sensitization.

Main Results:

  • (Meth)acrylate monomers are potent irritants and can induce active sensitization upon patch testing.
  • Patients allergic to acrylates often exhibit multiple positive patch tests.
  • These reactions may be due to cross-reactivity between different acrylates or sensitization to undisclosed impurities in products.
  • (Meth)acrylates are volatile and unstable, degrading rapidly when exposed to air, impacting allergenicity and patch test reliability.

Conclusions:

  • Acrylate allergy is a significant concern due to their widespread use and sensitizing potential.
  • Multiple positive patch tests in acrylate-allergic individuals warrant further investigation into cross-reactions and product composition.
  • The volatility and instability of (meth)acrylates pose challenges for accurate diagnosis and allergen management.
