Dialysis-induced oxidative stress: biological aspects, clinical consequences, and therapy.

Oxidative stress, which results from a rupture in the natural balance between pro- and antioxidant systems, is considered as a major factor in dialysis-associated morbidity and mortality. Emerging pharmacologic and dialytic antioxidant therapeutic and dialysis strategies should enable us to reduce the harmful consequences of oxidative stress in dialysis patients. Moreover, since there is increasing evidence of oxidative stress long before the initiation of maintenance dialysis, antioxidant therapeutic strategies should probably be developed very early in the course of renal failure.
