What type of hypersensitivity is associated with latex allergies?

Latex allergies are indeed associated with both Type I and Type IV hypersensitivity reactions.

Type I hypersensitivity, also known as immediate hypersensitivity, involves an IgE-mediated response. In the case of latex allergies, exposure to latex proteins can trigger an immune response that leads to symptoms such as anaphylaxis, hives, or asthma shortly after exposure. This rapid response is crucial to understanding the immediate dangers faced by individuals with severe latex allergies.

Type IV hypersensitivity, on the other hand, is a delayed-type hypersensitivity that typically manifests 24 to 72 hours after exposure to an allergen. This reaction involves T cells and is not antibody-mediated. In latex allergy, individuals may develop contact dermatitis after repeated exposure to the latex gloves or products, resulting in irritation and rashes.

Recognizing that latex allergies can involve both immediate and delayed hypersensitivity reactions helps healthcare professionals understand the various clinical presentations and manage patient care effectively. It underscores the importance of recognizing and accommodating the different types of hypersensitive responses in patients.
