Hypersensitivity reactions during haemodialysis: the choice of methods and assays
1Akzo Research Laboratories Obernburg, Department Arlo-CDB, Germany.
Abstract:
Our considerations about assays to assess agents and mechanisms involved in hypersensitivity reactions can be summarized as follows. The measurement of total IgE is recommended since it confirms a history of atopy of the patient and is a quick and inexpensive laboratory assay. If, based on the anamnesis, a particular allergen can be suspected to be involved in the clinical reaction a RAST against this compound is highly recommended. In any case of a severe clinical reaction the RAST against ethylene oxide is mandatory to confirm or exclude the involvement of ethylene oxide. The radioallergosorbent test (RAST) should not be used as a screening test for an entirely unknown allergen. The determination of histamine in plasma samples can be applied for specific scientific questions but cannot be recommended as a routine test with first priority. In contrast, the measurement of bradykinin should be established as soon as possible as a routine test for all new materials which are developed for application in the extracorporeal circuit. An initiative of the haemodialysis community is recommended to assure the commercial availability of a reliable bradykinin immunoassay.

Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...
