Asociación entre hiperfosfatemia y mortalidad en los pacientes con insuficiencia renal crónica terminal en terapia de reemplazo de la función renal con diálisis peritoneal o hemodiálisis

Objective: to evaluate the risk of mortality in patients with renal chronic disease stage V with increased serum phosphorus levels to more than 6.5 mg%. Design: retrospective cohort with 273 patients in dialysis, 70% in peritoneal dialysis and 30% in hemodialysis between 1999-2003 in a single dialysis center in Villavicencio (Colombia). Methods: the mortality rate for the patients with increased phosphorus levels to more than de 6.5 mg% was calculated and the survival analysis was made with the Kaplan-Meier method. Results: the mean of age at the beginning of dialysis was 52.7 years, 30.1% diabetics, 46.2% high blood pressure; the mean phosphorus level was 4.73 mg%, mean serum calcium 9.05 mg% and PTHi 173, 7 UI/ml. 98 death cases were recorded. The survival curves for the patients with mean phosphorus
