摘要

End stage-renal-disease (ESRD) is associated with dyslipidemia and premature atherosclerosis. The study evaluates the effect of hemodialysis (HD) on HDL-remodeling between pre- and post-HD. Was conducted a cross-sectional study with 50 ESRD male patients, undergoing HD at Ana Neri Hospital, Salvador, Brazil. All individuals were on HD for at least 3 months, into a three style="font-family:;" "=""> style="font-family:Verdana;">sessions style="font-family:;" "=""> style="font-family:Verdana;">protocol for 3 style="font-family:;" "=""> style="font-family:Verdana;">- style="font-family:;" "=""> style="font-family:;" "=""> style="font-family:Verdana;">4 hours per week, with a polysulfone low-flow basic-dialyzing-membrane and unfractionated-heparin. HDL Phospholipid-incorporation was measured by style="font-family:Verdana;">14 style="font-family:Verdana;">C-PL-scintillation-counting, expressed as % style="font-family:Verdana;">14 style="font-family:Verdana;">C-PL/mL/hour. Paraoxonase (PON-1) activity was measured by spectrophotometry using paraoxon as substrate. Cardiovascular risk ratios and atherogenic index of plasma were calculated. style="font-family:;" "=""> style="font-family:Verdana;">Total cholesterol, HDL-C and non-HDL-C increased at post-HD on all age groups, but without triglycerides (TG) changes.
