BACKGROUND Determination of the erythrocyte sedimentation rate (ESR) is a simple diagnostic tool for estimating systemic inflammation. It remains unclear whether ESR is influenced by renal disease or renal replacement therapy (RRT). OBJECTIVE To report the incidence and extent of ESR elevations in patients with chronic kidney disease (CKD) and the possible impact of RRT. METHODS We performed a single-center, retrospective study in inpatients with or without renal disease and in those with RRT, comparing ESR levels and other laboratory and clinical information. RESULTS A total of 203 patients were included. On average, ESR was elevated (mean [SD], 51.7 [34.6] mm/h), with no statistically significant difference between the patient groups. Only those receiving PD showed significantly higher ESR (78.3 [33.1] mm/h; P < .001). CONCLUSIONS ESR testing can be used without restriction in patients with CKD and in patients undergoing hemodialysis and who have received kidney transplantation; however, this measurement should be monitored carefully in patients with PD.
