[IgE-mediated allergy to ethylene oxide in hemodialyzed patients].
Ethylene oxide (ETO) is widely employed in sterilization of hemodialysis materials. Many studies have shown that ETO may act as an antigenic compound when bound to human albumin, therefore eliciting allergic reactions during hemodialysis. In the present study, we investigated in 93 patients undergoing long-term hemodialysis the prevalence of sensitization to ETO. All the patients were investigated for the presence of allergic or pseudo allergic reactions during the treatment. Specific IgE to ETO were found in sera of 3 patients: 1 suffered from urticaria and 1 from glottic edema and hypotension during the dialysis. The third one had non symptoms. The employ of a gamma-rays sterilized filter determined the disappearance of clinical manifestations in the two symptomatic patients, therefore suggesting a pathogenetic role of the specific IgE to ETO in determining the clinical manifestations.
