Allergic urticaria

The circulatory effects are manifested as arteriolar dilation and increased capillary permeability, causing plasma loss. The localized redness, edema (hives, wheal), and diffuse redness seen in allergic urticaria (rash) or physical skin injury result from these circulatory changes. Vasodilation also causes a decrease in blood pressure. 

Allergic urticaria. Histamine and other pro-inflammatory substances are released from mast cells in the skin and tissues in response to the binding of allergen-bound IgE antibodies to high-affinity cell-surface receptors. Basophils and other inflammatory cells release histamine and other mediators, and are thought to play an important role, especially in chronic urticarial diseases.

Radio contrast media may cause serious immediate pseudo allergic reactions such as urticaria/angioedema, bron-chospasm, shock, and death. These reactions have been reduced with the introduction of non-ionic, lower-osmolality products. Because a small percentage of patients who have reacted previously to radiocontrast media will react if re-exposed, several steps should be taken to prevent reactions, including ...
