the level of native and oxidized lipoproteina in children with nephrotic syndrome objective to investigate lipoproteina lpa oxidized lpa oxlpa and lpa immune complex lpaic levels in children with nephrotic syndrome nsdesign and methods plasma lpa oxlpa and lpaic levels were determined in 106 ns children in acuteperiod 42 in remission and 155 controlsresults lpa and oxlpa levels were significantly higher in acuteperiod and remission ns than in control oxlpa levels in acuteperiod ns were higher than in remission lpaic levels in acuteperiod ns were higher than in control lpa oxlpa and lpaic were found negatively related with albumin in ns lpa oxlpa and lpaic levels decreased after use of steroid therapy multiple linear regression analysis found relative change of albumin creatinine urea triglyceride and high density lipoprotein cholesterol accounted for 789 of variation in oxlpaconclusions lpa oxlpa and lpaic levels were increased in ns children which may play an important role in the processes of atherosclerosis
