Abstract

In nine chronic haemodialysis patients a desferrioxamine (DFO) load test (40 mg/kg body-weight) was performed 1 year after the beginning of treatment with recombinant human erythropoietin (rHuEpo). The patients were then divided into two groups. Group A comprised five patients with a greater mean aluminium (204 +/- 28 micrograms/l) than the four patients in group B. Group A was given a mean dose of 25.8 g (range 14-39 g) of DFO over 6 months. Group B (aluminium values 112 +/- 36 micrograms/l) was never treated with DFO. During the period of observation, plasma iron, serum ferritin and transferrin, as well as iron supplementation, did not differ between the groups. After DFO treatment a second DFO load test was performed. The mean predialysis aluminium value was significantly reduced in group A (204 +/- 28 vs 111 +/- 72 micrograms/l; P less than 0.05), while remaining unchanged in group B (112 +/- 36 vs 140 +/- 39 micrograms/l; P = ns). In both groups, the doses of rHuEpo necessary to maintain the same haemoglobin values decreased with time, but reduced significantly only in group A (298 +/- 105 vs 110 +/- 61 mu/kg per week; delta -63%; P less than 0.01). Thus, aluminium interferes with the response to rHuEpo in haemodialysis pa...Continue Reading

Anemia

Anemia develops when your blood lacks enough healthy red blood cells. Anemia of inflammation (AI, also called anemia of chronic disease) is a common, typically normocytic, normochromic anemia that is caused by an underlying inflammatory disease. Here is the latest research on anemia.
