摘　　要：AIM： To evaluate determinants of infammatory mark-ers in chronic renal failure patients according to the level of glomerular fltration rate. METHODS： One hundred ffty four patients （Age： 44 ± 06 years; male/female： 66/88） with chronic renal fail-ure （CRF） were divided into 6 groups according to the National Kidney Foundation （NKF） classification. They included 28 primary stage renal failure patients （CRF 1）, 28 moderate stage renal failure patients （CRF 2）,28 severe stage renal failure patients （CRF 3）, 18 end-stage renal failure patients （CRF 4）, 40 hemodialysis （HD） patients, and 12 peritoneal dialysis （PD） patients. Tumor necrosis factor-α （TNF-α）, interleukin-1β （IL-1β）, interleukin-6 （IL-6） and C-reactive protein （CRP） were analyzed by immunosorbent assay kit （ELISA） （Cayman Chemical’s ACETM EIA kit）. Immunoassay methods were used for total homocysteine （tHcy） （fuorescence polarization immunoanalysis HPLC, PerkinEmer 200 series）, transferrin （MININEPHTM human transferin kit： ZK070.R）, ferritin （ADVIA Centaur ） and fbrinogen analysis （ACL 200）. Differences between groups were performed using SPSS 20.0 and data are expressed as the mean ± SD.RESULTS： Results showed that in comparison with CRF 1 group and other groups, TNF-α and IL-6 levels were respectively more elevated in HD （16.38 ± 5.52 pg/mL vs 0.39 ± 0.03 pg/mL, 11.05 ± 3.59 pg/mL vs 8.20 ± 0.22 pg/mL, P 〈 0.001） and PD （14.04 ± 3.40 pg/mL vs 0.39 ± 0.03 pg/mL, 10.15 ± 1.66 pg/mL vs 8.20 ± 0.22 pg/mL, P 〈 0.001）. IL-1β levels were increased in HD （9.63 ± 3.50 pg/mL vs 3.24 ± 0.10 pg/mL, P 〈 0.001） and CRF 4 （7.76 ± 0.66 pg/mL vs 3.24 ± 0.10 pg/mL, P 〈 0.001） patients than in CRF 1 and in the other groups. Plasma tHcy levels were higher in HD （32.27 ± 12.08 μmol/L） and PD （28.37 ± 4.98 μmol/L） patients compared to the other groups of CRF （P 〈 0.001）. The serum CRP level was signifcantly increaseAIM: To evaluate determinants of inflammatory markers in chronic renal failure patients according to the level of glomerular filtration rate.
