The severity of allergic reactions to latex-containing products ranges from mild {{c1::contact dermatitis}} to life threatening anaphylaxis.
Extra
Most serious latex allergies seem to involve a direct IgE-mediated immune response to polypeptides in natural latex, although some cases of contact dermatitis may be due to a type IV sensitivity reaction to chemicals introduced in the manufacturing process.
- Nonetheless, a relationship between the occurence of contact dermatitis and the probability of future anaphylaxis has been suggested.
Anaphylactoid reactions resemble anaphylaxis but do not depend on IgE antibody interaction with antigen. They are clinically indistinguishable and equally life threatening.
In many instances of hypersensitivity reactions to drugs used in anesthetic procedures, the patients had no previous exposure to the agent. Some over the counter drugs, cosmetics, and food products, many of which contain tertiary or quaternary ammonium ions, can sensitize susceptible individuals.
