Evaluación de la administración de carboximaltosa férrica intravenosa en la consulta de enfermedad renal crónica avanzada, para el control de la anemia

Abstract

Ferric carboxymaltose is a safe and easy dosage of intravenous iron formulation; it can be administered intravenously up to 1 gram in a single session and allows time savings of patients and nursing. We present the results of his administration in a unit of chronic kidney disease, analyzing the results and the impact on the workload of the nursing staff.
Materials and methods: All patients followed in the chronic kidney disease unit at our center from January 2011 to December 2014 and who received intravenous iron carboxymaltose were analyzed. Their baseline data and clinical and laboratory results at six months were recorded.
Results: 85 patients were identified during this period. Mean age of 72 ± 12 years, with a baseline estimated glomerular filtration rate of 28 ± 11 ml / min and at six months of 30 ± 11 (p >0.05). Baseline and at six months hemoglobin levels were 10 ± 4 and 11 ± 3 g / dl, respectively (p<0.001). The basal and final hematocrit were: 34 ± 4 vs 39 ± 6% (p<0.001). Baseline ferritin levels and transferrin saturation index versus levels at six months were respectively: 88 ± 97 vs 308 ± 327 ng / ml (p <0.001) and 11.2 ± 6 vs 11 ± 22.3 (p <0.001 ). Since the average administration time by any formulation of intravenous iron is 30 minutes, the estimate based on the number of administrations is a saving of 85 and 170 hours on these four years when compared with formulations that require three to five respectively sessions. In turn, the number of punctures has been reduced without associated complications observed.
Conclusion: Carboxymaltose iron is safe and effective showing a recovery of hemoglobin levels and iron deposits. Its ease of administration has allowed substantial time savings. This, together with its few side effects makes it ideal for outpatient administration.
