Abstract
OBJECTIVE To investigate the effect of different intravenous iron treatment regimens on anemia and oxidative stress in maintenance hemodialysis (MHD) patients. METHODS A total of 58 MHD patients were randomly divided into a multi-frequency low-dose intravenous iron group (iron sucrose 25 mg, twice a week for 8 weeks, n=19), a less-frequency regular-dose intravenous iron group (iron sucrose 100 mg, once every two weeks for 8 weeks, n=19), and a non-iron group (n=20). Another 20 healthy people served as a control group (n=20). The changes of hemoglobin (Hb), hematocrit (HCT), serum ferritin (SF) and transferrin saturation (TSAT), as well as the oxidative stress parameters of malon-dialdehyde (MDA), superoxide dismutase (SOD) and myeloperoxidase (MPO) were detected before and after the treatment. RESULTS After 8 weeks, compared with the non-iron group, the levels of Hb, HCT, SF and TSAT in the two iron groups were significantly elevated (P<0.01), but there was no difference between the two iron groups (P>0.05). After the single dialysis, the two iron groups had higher level of serum MDA, MPO and lower level of serum SOD than that of the non-iron supplementation group (P<0.01). The multi-frequency low-dose intravenous iron group had lower level of serum MDA [(5.37 +/- 0.73) nmol/mL vs (6.37+/-1.67) nmol/mL], MPO [(81.41+/-7.60) U/L vs (96.75+/-16.97) U/L] and higher level of serum SOD [(84.77 +/- 14.02) U/mL vs (68.23 +/- 4.90) U/mL] than that of the less-frequency regular-dose intravenous iron group. After 8 weeks, there was no significant difference between the two iron groups (P>0.05). CONCLUSION Multi-frequency low-dose intravenous iron can effectively improve anemia in MHD patients, whose acute oxidative stress is lower than that of less-frequency regular-dose intravenous iron, and is a relatively safe and effective intravenous iron treatment regimen.

Abstract
OBJECTIVE To compare the diuretic effect of coadministration of dextran and flurosemide with that of coadministration of Albumin and flurosemide on primary nephrotic syndrome. METHODS In a double-blind placebo-controlled study, eighteen primary nephrotic syndrome patients on standard sodium chloride intake, random by divided into three groups and received by intravenous administration for 60 minutes for three days (a) FU (1 mg.kg-1) combination with a sham infusion, (b) FU (1 mg.kg-1) combination with 50 ml of 20% solution of Albumin, or (c) FU (1 mg/kg) combination with 250 ml dextran 40. Urinary volume, sodium and plasma atrial nartiuretic peptide concentration were assessed. RESULTS The results showed that administration of FU alone increased mean cumulative urinary sodium and volume excretion as compared with the administration of sham infusion without treatment (P < 0.05). The administration of FU and albumin or FU and dextran 40 caused an even more marked increase of urinary sodium and volume excretion (P < 0.01), as compared with the administration of sham infusion without treatment. Plasma ANP increased significantly on both albumin infusion days and dextran 40 infusion days (P < 0.05). CONCLUSION Coadministration of albumin and FU or dextran 40 and FU can increase the urinary volume and urinary Na and ANP significantly, dextran 40 can take the place of albumin because there was no difference between the administration of FU and albumin and FU and dextran in UV, Una and ANP.
