Effect of vitamin E-bonded dialyzer on eosinophilia in haemodialysis patients.

Background: Eosinophilia in haemodialysis patients probably results from allergy to haemodialysis-related materials, including dialyzer membranes. We examined the effects of vitamin E-bonded dialyzers on eosinophil counts in haemodialysis patients.

Methods: We enrolled seven patients who were on regular haemodialysis and had sustained eosinophilia.
