RESUMO
Iron Supplementation is crucial in raising hematocrit as well as dosage saving for recombinant human erythropoietin therapy (rHuEPO) in maintenance hemodialysis patients. Intravenous iron has proved to be both safe and efficacious in this patient's population. However, the exact iron requirement has not been worked our. In this study we found that 1000 mg of element iron (given as iron saccharate) per moth was effective in maintaining hematocrit and hemoglobin at 33% and 110 gm/L respectively, and reducing the erythropoietin (EPO) dosage by about 20% in maintenance hemodialysis patients who were iron-replete. The serum ferritin increased from 219+/-144 to 320+/-234 microg/L (P< 0.05). There were no major side effects and patients tolerated the monthly iron therapy well. Our study suggests that intravenous iron saccharate (100 mg/month) is effective and safe in patients on maintenance hemodialysis receiving RHUEPO.
RESUMO
Chronic renal failure is associated with decreased production of active vitamin D and also results in altered lymphocyte population. We studied the effect of alfacalcidol on lymphocyte phenotype. There were 15 patients (10 males, 5 females) with a mean age of 54.3+/-14.4 years who had been on chronic maintenance haemodialysis for a mean period of 3.2+/-1.5 years. Intravenous alfacalcidol was given three times weekly during dialysis for a duration of 6 months. Our results show a significant increase in NK cells from 0.20+/-0.12 to 0.27+/-0.28 (P=0.001), without a significant change in CD2, CD19, CD4, CD8 population, and CD4/CD8 ratio.
