Regenerated cellulose membranes are widely used in the treatment of renal failure. The presence of hydroxyl (OH) groups on the membrane surface plays an important role in initiating complement activation and also influences thrombogenicity. The OH groups may be masked or reduced by alteration of the manufacturing process of the membrane. We have undertaken a clinical study of four cellulose-based membranes (Cuprophan, Hemophan, cellulose acetate, and cellulose triacetate) in which the hydroxyl groups of the membrane have been replaced and the magnitude of replacement has varied from less than 1% to greater than 80%, to assess the role that these modifications play in functional performance, biocompatibility (neutropenia, leukocyte activation, anaphylatoxin generation, and hypoxaemia). Our findings indicate that there does not appear to be a straightforward correlation between the numbers of hydroxyl groups replaced and modification of biocompatibility, suggesting that not all hydroxyl groups behave in a similar way.
