Immunology, allergic

In this context, cell infiltrates consisting of leucocytes and lymphocytes can be found within the acinus and/or in the portal field in contrast, in immunological-allergic impairment mechanisms, it is primarily lymphocytic and eosinophilic-leucocytic infiltrations that become manifest. This cellular reaction is also reversible. 

Special observations in patients with agranulocytosis favor an immunological/allergic mechanism rather than a toxic one. Several points justify this view ...

Immunologic Allergic reactions, such as anaphylaxis and transfusion reactions, are potential adverse reactions to prothrombin complex concentrates [32 ]. Patients with IgA deficiency and anti-IgA antibodies can have anaphylactic reactions after exposure to IgA-containing blood products, including prothrombin complex concentrates [71 ]. 

Immediate contact reaction Immunologic (allergic) or non-immunologic (irritant), urticarial or non-urticarial reactions does not define the appearance of the reaction Allergic and non-allergic urticarial reactions Immediate-type irritancy Non-allergic urticarial or non-urticarial reactions... 

Coombs and Gell (1963) have classified all immunologic (allergic) reactions into four types (I to IV). The classification of Types I to III depends on whether antigen or antibody is cell-fixed or in solution. Type IV is cell-mediated and is typified in the skin by responses such as the tuberculin reaction which develops macroscopically over 36-48 hr and lasts for 72-96 hours. This is the classical delayed hypersensitivity reaction. 

Immunologic Allergic reactions to lido-caine for fiberoptic bronchoscopy have been reviewed [57 ]. The authors concluded that lidocaine is safe in bronchoscopy, provided that care is taken to limit the dose. In suspected local anesthetic allergy they suggested patch testing before the use of any topical anesthesia. 

Immunologic Allergic reactions to intravenous aprotinin continue to be reported, as in the case of a 67-year-old man who had been treated with an aprotinin-contain-ing fibrin sealant and 3 years later had an anaphylactic reaction after intravenous administration of aprotinin, associated with aprotinin-speciiic IgG and IgE antibodies [207 ], and a 66-year-old man who had anaphylactic shock within 2 minutes of a rapid infusion of aprotinin 4 million units following two previous infusions of 2 million units each [208 ].
