WebHypersensitivity reactions during hemodialysis findings from that interaction amongst blut- constituents and the hemodialysis membrane. Different types of membrane materials, including cellulose, substituted cellulose, or synthetic noncellulose, are used in dialyzers' manufacture which can affect the frequency and type of reaction seen. WebType A reactions occur in a reuse setting, alos, and these may be related to some as yet poorly understood interaction between bleach, reuse sterilants, and certain dialyzer membranes, again, with ACE inhibitors playing an amplifier role. There is no compelling evidence linking membrane-induced complement activation to type A dialyzer reactions.
