Compared with iron dextran, iron chondroitin sulfate(ICS) is much cheaper and has
better bioavailability. To evaluate the efficacy and safety of ICS in maintenance HD
patients, i.v. ICS was given to 37 HD patients [20 M, 17 F, median age 51 years,
median duration of HD 21 months] whose ferritin(Fer)<100§¶/L or transferrin
saturation(TFS) <20% [Group1, 12 M, 10 Fl or Hb<9.0g/dL in spite of increased
rHuEPO dose, Fer¡Ã100§¶/L anti TFS¡Ã2% [Group, 8 M, 7 F]. The patients had taken
oral iron [227¡¾73mg/day(mean¡¾SD)] before this study. All patients received 120mg i.v.
ICS weekly for 1 month. Then, ICS dosage was adjusted to 40-120mg/week depending
on Hb, Fer and TFS in the following 3 months. Hb, Fer, TFS, rHuEPO dose and side
effects were monitored monthly. The results were as fouows:
1) 1.v. iron therapy Produced a significant rise in b(8.3¡¾0.9g/dL to 9.7¡¾0.9g/dL;
p<0.01), a significant reduction in rHuEPO dose(95¡¾50U/kg/wk to 69¡¾28U/kg/wk;
p<0.05), a significant increase in serum ferritin levels(162¡¾149§¶/L to 472¡¾25§¶/L
;p<0.01) and TFS(24¡¾13% to 41¡¾18%; p<0.05).
2) In group 1, i.v. iron therapy Produced a significant rise in Hb(8.5¡¾1.1g/dL to 9.9¡¾
0.9g/dL; p<0.01), a significant reduction in rHuEPO dose(87¡¾45§¶/kg/wk to 69¡¾
27U/kg/wk; p<0.05), increased serum ferritin levels(90¡¾48§¶/L to 379¡¾186§¶/L 94,
p<0.01) and TFS(18¡¾9% to 36¡¾ 16%, p<0.05).
3) In group 2, i.v. iron therapy Produced a significant rise in Hb(8.1¡¾0.6g/dL to 9.3¡¾
0.9g/dL; p<0.01), a significant reduction in rHuEPO dose(108¡¾55U/kg/wk to 69¡¾
3U/kg/wk; p<0.05) and increased serum ferritin levels(274¡¾185§¶/L to 602¡¾287§¶/L;
p<0.01) with a tendency of increase in TFS(35¡¾13% to 41¡¾18%; p=0.06).
4) No significant side effect was observed.
5) An annual cost reduction of 221 US dollars per patient was expected.
In conclusion, ICS is an effective and safe intra-venous iron preparation in HD
patients.
