[Hypersensitivity phenomena in dialysis patients. Incidence of eosinophilia, raised IgE and ethyleneoxide-induced antibodies].

The hypersensitivity parameters eosinophil count, serum IgE and IgE-type antibodies to ethylene oxide-albumin conjugates (ETO-antibodies), were determined in 182 dialysis patients. Eosinophilia was seen in 21.7% of patients, IgE elevation in 21.4% and ETO-antibodies in 12.4%. A pathological change in at least one of the measured parameters was present in 33.1%. The appearance of ETO-antibodies was frequently associated with severe clinical symptoms, especially asthma and anaphylactic shock. Sensitisation is apparently common in dialysis patients. Since ETO-antibodies are often associated with severe clinical symptoms, their presence should be sought in those dialysis patients showing incompatibility reactions or asthma.
