Oxysterols are increased in plasma of end-stage renal disease patients.

Background/aims: Oxidative stress occurs in chronic renal failure patients undergoing hemodialysis (HD). The objective of our study was to measure oxidation products of cholesterols, so-called oxysterols, in the serum of HD patients in comparison to healthy control persons.

Methods: In 42 HD patients, plasma oxysterols were measured before and after HD.
