Comparison of oral versus intravenous iron therapy in predialysis patients of chronic renal failure receiving recombinant human erythropoietin.
OBJECTIVE
To compare oral versus intravenous iron in pre-dialysis patients of chronic renal failure (CRF) receiving recombinant human erythropoietin (rHuEPO).


METHODS
The study was undertaken in 40 adult patients of chronic renal failure. The patients were randomly divided into two groups A and B of 20 patients each. Group A patients were given oral iron and group B patients were given intravenous iron. All patients in both groups were given recombinant human erythropoietin 2000 IU twice weekly subcutaneously. The study was carried for up to three months. Patients were monitored every month for renal parameters and haematological parameters which included haemoglobin, reticulocyte count and packed cell volume. Ferrokinetic studies were done at baseline and at three months.


RESULTS
It was observed that haematological parameters showed significant statistical improvement in the intravenous iron group as compared to group A (oral iron group). The ferrokinetic studies revealed that serum iron, serum ferritin and transferrin saturation, decreased significantly in oral iron group, whereas significant increase was seen in group B (intravenous iron group). None of the patients developed any adverse effects because of erythropoietin or iron therapy.


CONCLUSIONS
Concomitant use of intravenous iron is better than oral iron in CRF patients treated with rHuEPO. The intravenous route of iron administration may be a preferred route along with rHuEPO therapy, more so in the Indian context where prevalence of iron deficiency anaemia is fairly high.
