Abstract

Plasma lipid peroxidation in noninsulin dependent diabetes mellitus (DM) patients were evaluated in DM patients undergoing hemodialysis (HD) by means of a chemiluminescence-HPLC for the specific determination of phosphatidylcholine hydroperoxide (PCOOH). Thirty-three uremic patients with DM nephropathy, undergoing 12 hours HD a week using polymethylmethacrylate membrane, were studied. Of them 22 DM patients on HD were divided into 2 age and sex matched groups treated and conventional group in order to clarify therapeutic effect of 500 mg alfa-tocopherol and 600 mg probucol daily. Fifty DM patients without end-stage renal disease (ESRD) who were age-, period of diabetes-, and sex-matched, were selected as positive control of the subjects. Plasma PCOOH levels were significantly elevated in both DM patients, while the plasma PCOOH in normal controls were 227.0 +/- 68.7 pmol/ml. Plasma PCOOH levels of DM patients undergoing HD were significantly higher than that of patients without ESRD (1,330.8 +/- 642.7 pmol/ml vs. 756.6 +/- 431.9 pmol/ml, p < 0.025). Partial correlation coefficient of plasma PCOOH level demonstrated PCOOH and period of HD in DM patients were highly significantly positively correlated (p < 0.01), although single ...Continue Reading
