NCT00974779

Brief Summary

The purpose of this study is to test whether a dialyzer with a higher than usual permeability for proteins can eliminate proinflammatory proteins from the blood of patients on regular maintenance hemodialysis who have chronically elevated levels of inflammation markers such as C-reactive protein (CRP) in their blood.
