Cinnamic aldehyde is used as a flavoring agent, ingredient of fragrance in soft drinks, ice creams, dentifrices, pastries, chewing-gum, etc. It can induce both contact urticaria and delayed-type reactions. It can be implicated in contact dermatitis in those who work in the perfume industry or food handlers. Cinnamic aldehyde is contained in the fragrance mix . [Pg.1138]

Delayed type hypersensitivty (DTH) reactions (synonym type IV allergic reactions) are exaggerated, T-lymphocyte mediated, cellular immune reactions to foreign substances, which require one to two days to manifest clinical symptoms. [Pg.420]

Cell-mediated immunity (CMI) is the result of the activity of many leukocyte actions, reactions, and interactions that range from simple to complex. This type of immunity is dependent on the actions of the T lymphocytes, which are responsible for a delayed type of immune response The T lymphocyte becomes sensitized... [Pg.567]

Some types of allergic reaction, for example immediate or delayed-type skin allergies, serum-sickness-like reactions and anaphylactic reactions, may occur in a proportion of patients given penicillin treatment. There is some, but not complete, cross-allergy with cephalosporins. [Pg.103]

Type IV reactions are mediated by T cells themselves. Delayed-type hypersensitivity reactions from positive tuberculin tests to contact dermatitis are typical type IV reactions, but understanding T-cell function allows us to further define this category, as shown in Table 51-1. [Pg.821]

Allergic contact dermatitis is a delayed hypersensitivity reaction.30 Upon initial exposure, a substance penetrates the skin, binds to a protein and develops into sensitizing antigens. Subsequent exposures to that substance will then elicit an allergic reaction.25,29,30 Symptoms of allergic contact dermatitis are similar to those of the irritant type, but may take several hours to several days to develop following re-exposure.25,26... [Pg.967]

It is also more or less accepted that T-cells, in particular T-helper cells (CD4+), may develop into either Thl cells or Th2 cells. By doing so, T-helper cells orchestrate the ensuing immune response by the types of cytokines they produce. Thl cells, by producing IL-12 and y-IFN, stimulate macrophages and/or cytotoxic T-cells to kill and destroy infected or malignant cells, or to initiate a delayed type hypersensitivity (DTH) reaction Th2 cells, by producing IL-4, IL-5, IL-10, IL-13, trigger B-cells to initiate antibody production. [Pg.64]

Type IV Delayed-type Hypersensitivity (DTH). Delayed-type hypersensitivity reactions are T-cell mediated with no involvement of antibodies. However, these reactions are controlled through accessory cells, suppressor T cells, and monokine-secreting macrophages, which regulate the proliferation and differentiation of T cells. The most frequent form of DTH manifests itself as contact dermatitis. The drug or metabolite binds to a protein in the skin or the Langerhans cell membrane... [Pg.554]
