Studies have shown that presence of a failed kidney transplant in patients returning to chronic hemodialysis following failure of their kidney transplant is associated with chronic inflammatory state and erythropoietin resistance. The aim of our retrospective clinical study was to analyze erythropoietin requirements in chronic hemodialysis patients after failure of kidney transplant. Patients and methods Fifteen chronic hemodialysis patients after failure of kidney transplant, 11 males and 4 females, at the mean age of 47.3 ± 13.3 years (range 21–65 years), were included in the study. Twelve patients had a failed kidney transplant still in place (group A) and 3 patients were had had a failed transplant nephrectomy (group B). Hemoglobin level (Hb), erythropoietin dose per week (EPO/week), erythropoietin dose per week per dry body weight (EPO/week per bw), erythropoietin resistance index (ERI = EPO/week per bw per Hb), C‐reactive protein (CRP), albumin level, ferritin level, transferrin saturation (TS) and creatinine level were analyzed monthly from January to September 2004.

They exhibited higher erythropoietin resistance with worse anemia and worse biochemical parameters characteristic of chronic inflammatory state compared to chronic hemodialysis patients after a failed transplant nephrectomy.
