delayed hypersensitivity

Delayed hypersensitivity to the metal in your ring is not uncommon even after several years.

Delayed hypersensitivity does not start to be noticeable until several hours to a full day after exposure to the antigen.

It has been suggested that the disease is primarily auto-immune in nature, being a delayed hypersensitivity reaction to any of the above agents.

Over time, there is the risk of serum sickness, which is a delayed hypersensitivity response to the medication.

Langhans giant cell occurs frequently in delayed hypersensitivity.

It can trigger allergic reactions and delayed hypersensitivity reactions in people sensitive to horse proteins.

In thymectomized animals, the ability to reject allografts, and to mount delayed hypersensitivity responses, was drastically reduced.

An idiosyncratic, delayed hypersensitivity reaction has been implicated in the pathophysiology of Stevens-Johnson syndrome.

It causes antibody formation and delayed hypersensitivity when bound to aromatic amino acids, polypeptides or proteins.

Still experimental, skin tests with soluble extracts of human or bovine uveal tissue are said to elicit delayed hypersensitivity responses in these patients.

Gluten, the protein found in wheat, can lead to a damaged intestinal lining owing to a delayed hypersensitivity reaction, otherwise known as coeliac disease.

Atopy patch testing (APT) is an adapted form of patch test used to diagnose delayed hypersensitivity to foods in children.

A patch test (contact delayed hypersensitivity allergy test) is a commonly used examination to determine the exact cause of an allergic contact dermatitis.

Examples of these tools include the Prognostic Nutrition Index,[6,7] delayed hypersensitivity skin testing, institution-specific guidelines, and anthropometrics.

As such, ACD is termed a Type IV delayed hypersensitivity reaction involving a cell-mediated allergic response.

A MELISA test measures a so-called Type-IV delayed hypersensitivity reaction.

There are both immediate hypersensitivity reactions (types I and III) and delayed hypersensitivity reactions (type IV) to mosquito bites.

Some individuals may react to the antivenom with an immediate hypersensitivity reaction (anaphylaxis) or a delayed hypersensitivity (serum sickness) reaction and antivenom should, therefore, be used with caution.

Sympathetic ophthalmia is currently thought to be an autoimmune inflammatory response toward ocular antigens, specifically a delayed hypersensitivity to melanin-containing structures from the outer segments of the photoreceptor layer of the retina.

Huber B, Devinsky O, Gershon RK, Cantor H. Cell-mediated immunity: Delayed hypersensitivity and cytotoxic responses are mediated by different T-cell subclasses.

In this way, polyclonal antibodies inhibit cell-mediated immune reactions, including graft rejection, delayed hypersensitivity (i.e., tuberculin skin reaction), and the graft-versus-host disease (GVHD), but influence thymus-dependent antibody production.

Eventually House reveals that Nick's father, a food importer traveling around the world, contracted a Middle Eastern parasite which he then inadvertently transmitted to Abby sexually, triggering a cerebellar schistosomiasis delayed hypersensitivity allergy.

Transfer factors were originally described as immune molecules that are derived from blood or spleen cells that cause antigen-specific cell-mediated immunity, primarily delayed hypersensitivity and the production of lymphokines, as well as binding to the antigens themselves.

The development of cell-mediated immunity correlated with delayed hypersensitivity and an inflammatory response is associated with clinical cure, whereas the lack of or a defective cell-mediated immunity predisposes the host to chronic or recurrent dermatophyte infection.

The late phase of a Type 1 reaction (which develops 8-12 hours and is mediated by mast cells) should not be confused with delayed hypersensitivity Type IV allergic reaction (which takes 48-72 hours to develop and is mediated by T cells).
