- Mean hemoglobin level increased without erythropoiesis-stimulating agent after kidney transplantation.
- The hemoglobin level at one year after transplantation was significantly lower in recipients with ESA hyporesponsiveness.
- We report the pre-transplant ESA responsive index (ERI) was a sentinel marker for posttransplant anemia.
BackgroundAt the time of kidney transplantation (KT), almost all patients have anemia caused by low levels of endogenous erythropoietin (EPO), along with several other factors. After KT, anemia improves because of secretion of EPO from the allograft. But some recipients have persistent anemia. Whether or not erythropoiesis-stimulating agent (ESA) hypo-responsiveness before KT affects post-transplant anemia (PTA) remains unknown.MethodsSixty-eight patients received KT between January 2007 and July 2012 through the Department of Urology at Kobe University Hospital, and 35 of these patients were enrolled. Exclusion criteria included age <18 years, unknown ESA dosage at transplantation, ESA start within 1 year after transplantation, and other criteria. We evaluated post-transplant hemoglobin (Hb) levels from the pre-transplant ESA responsive index (ERI): pre-transplant ESA dosage/Hb à body weight at 1 year after transplantation.ResultsThe mean (±SD) Hb of all patients rose from 11.3 ± 1.0 mg/dL to 12.7 ± 1.4 mg/dL at 1 year after transplantation (P < .01). The pre-transplant low ERI group (<10) showed significantly higher hemoglobin levels compared with the pre-transplant high ERI group (â¥10; 12.9 ± 1.14 mg/dL versus 11.8 ± 1.76 mg/dL, respectively; P = .03).ConclusionsESA hypo-responsiveness before KT carried over after KT. Low pre-transplant ERI might be a sentinel marker for PTA.
