Anemia in pediatric dialysis patients in end-stage renal disease network 5.

To identify demographic and clinical characteristics associated with failure to achieve hemoglobin levels >/=11 g/dl in prevalent pediatric end-stage renal disease (ESRD) patients, a cross-sectional analysis of patient clinical data collected by the Mid-Atlantic Renal Coalition in conjunction with the 2000 and 2001 ESRD Clinical Performance Measures Projects was performed. Ninety-nine patients (mean age 12.6 years, SD 5.4) contributed 119 observations to this analysis. Of patients on hemodialysis, 36.6% were anemic, and 39.5% of patients on peritoneal dialysis (PD) were anemic. Associations between age, race, gender, assigned cause of ESRD, Kt/V, transferrin saturation, time on dialysis, serum albumin, dialysis modality, and the achievement of target hemoglobin were examined. In multivariate logistic regression analyses examining age, dialysis modality, time on dialysis, and serum albumin, each 1-year increase in age was significantly associated with hemoglobin levels <11 g/dl [adjusted odds ratio (OR) 1.18, 95% confidence interval (CI) 1.06-1.32] and PD patients were more than twice as likely to have hemoglobin levels <11 g/dl (adjusted OR 2.62, 95% CI 0.98-7.04). Patients on dialysis for 6 months or more were less likely to be anemic than those on dialysis for less than 6 months (adjusted OR 0.39, 95% CI 0.16-0.99). In conclusion, increasing age, dialysis for less than 6 months, and treatment with PD were predictive of anemia in this population.
