This study details an immediate allergic occupational asthma case caused by Bisphenol A diglycidyl ether (BADGE) epoxy resins (ERs). Prompt recognition of ER-related respiratory symptoms is crucial for worker health.
Area of Science:
- Allergy and Immunology
- Occupational Medicine
- Environmental Health
Background:
- Epoxy resins (ERs), particularly Bisphenol A diglycidyl ether (BADGE) ERs, are widely used in protective coatings and flooring.
- While ERs can cause allergic reactions, immediate hypersensitivity is considered rare.
Observation:
- A construction worker presented with dyspnea and skin symptoms exclusively when installing ER-containing floors.
- The patient had a history of occupational exposure to ERs.
Findings:
- Diagnostic tests confirmed an IgE-mediated allergy to BADGE ER, evidenced by positive serum IgE antibodies and skin prick tests.
- A specific bronchial challenge test with BADGE ER induced an immediate asthmatic reaction.
- Patch testing also revealed a positive reaction to BADGE ER.
Implications:
- This case represents the first documented instance of immediate allergic occupational asthma (OA) linked to BADGE ER exposure, confirmed by inhalation challenge.
- Highlights the importance of considering OA in individuals experiencing work-related respiratory symptoms when handling ERs.
- Emphasizes the need for prompt medical evaluation and recognition of potential immediate hypersensitivity reactions to ERs in occupational settings.

Antiasthma Drugs: Mast Cell Stabilizers and Anti-IgE Drugs
Mast cell stabilizers, such as cromolyn (also known as sodium cromoglycate) and nedocromil (Tilade), are effective drugs in asthma management. These stabilizers hinder histamine release by skillfully obstructing the activation of mast cells and other cellular entities. Notably, they navigate this task without...
Asthma-II: Pathophysiology and Classification
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:
Asthma-I: Introduction
Preparation of Epoxides
Epoxides result from alkene oxidation, which can be achieved by a) air, b) peroxy acids, c) hypochlorous acids, and d) halohydrin cyclization.
Epoxidation with Peroxy Acids
Epoxidation of alkenes via oxidation with peroxy acids involves the conversion of a carbon–carbon double bond to an epoxide using the oxidizing agent meta-chloroperoxybenzoic acid, commonly known as MCPBA. Since the O–O bond of peroxy acids is very weak, the addition of electrophilic oxygen of peroxy acids to...
Asthma: Pathogenesis and Management
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.
