Occupational asthma due to hexahydrophthalic anhydride: a case report.
Hexahydrophthalic anhydride (HHPA) belongs to the family of acid anhydrides, the members of which are reactive organic chemicals of low molecular weight widely used in alkyd and epoxy resins. The major toxic effects ofthe acid anhydrides are mucosal and skin irritation and respiratory hypersensitivity, particularly asthma. Most of the reported cases of asthma caused by acid anhydrides were due ...
متن کاملNew causes of occupational asthma.

The recent developments in the diagnostic tools employed in occupational asthma caused by new agents are summarized. RECENT FINDINGS Work exposures are a significant contributor to the burden of asthma and, therefore, there is great scientific interest in work-related asthma. Altho...
متن کاملTrimellitic anhydride induces low-grade mast cell degranulation without specific IgE
OBJECTIVES Low-molecular-weight (LMW) substances are known to be causative agents of occupational asthma (OA) and occupational rhinitis (OR). Although most LMW substances are irritants or allergens, some can cause immediate type immunoglobulin E (IgE)-mediated allergic reactions. Trimellitic anhydride (TMA) is one such LMW substance, which is known as an immunological sensitizer. However, the e...
متن کاملEffect of respiratory protective devices on development of antibody and occupational asthma to an acid anhydride.
STUDY OBJECTIVES To determine whether the use of respiratory protective equipment would reduce the incidence of occupational asthma due to exposure to hexahydrophthalic anhydride (HHPA). DESIGN Prospective cohort study. SETTING A facility that makes an epoxy resin product requiring HHPA for its manufacture. PARTICIPANTS Sixty-six individuals newly hired at a facility that makes an epoxy r...
متن کاملMechanisms of occupational asthma: Not all allergens are equal.
Asthma is a heterogeneous lung disorder characterized by airway obstruction, inflammation and eosinophil infiltration into the lung. Both genetics and environmental factors influence the expression of asthma, and not all asthma is the result of a specific immune response to allergen. Numerous asthma phenotypes have been described, including occupational asthma, and therapeutic strategies for as...
