Total dose infusion of intravenous iron in patients with chronic kidney disease receiving haemodialysis.

摘要

A regimen of a single high dose iron administration was initially adopted for patients commencing haemodialysis (HD) treatment. Iron stores are established and iron metabolism and erythropoiesis stabilise allowing haematinic parameters to be more confidently assessed for use in anaemia management decisions. High doses of IV iron delay the need for subsequent iron supplementation. A high-dose, low-frequency iron infusion regimen for all HD patients was adopted. The outcomes of administering this dosage regimen are reported as observational retrospective analysis using patient record data in 2009. Patients received three [median; semi-interquartile range (SIQR) 0.5] high-dose iron infusions during the year. The median infusion dose was 1100 mg iron (SIQR 0.0) and the median amount of iron received during the year by each patient was 3200 mg (SIQR 750). The median haemoglobin (Hb) level prior to infusion was 108 g/l and post infusion 114 g/l; ZHb = 2.656, p = 0.008). Ferritin levels increased from a median of 376 mug/l preinfusion to 690 mug/l postinfusion; Zferritin =-4.796, p < 0.001. The median time between infusions was 125 days (approximately four months). The 51 patients (76%) who received three or less infusions within the study period received 2537 mg (mean) of iron. These findings indicate that both Hb and ferritin levels can be adequately managed using a high-dose, low-frequency regimen of IV iron in patients undergoing HD.
