BackgroundAnemia is common among end-stage renal disease ESRD patients who undergone hemodialysis. The total reduction of red blood cell RBC count is associated with poor prognosis in these patients. Although erythropoietin EPO has been used as an effective treatment for ESRD patients with anemia, a large number of patients still present poor responses to EPO treatment.

MethodsWe measured T-cell receptor sequencing profiles, including length of complementarity-deteremining region 3 CDR3, intra- and inter-group EPO resistant vs. responsive clonotype diversity, VDJ usage profiles and V-J combinations from ESRD patients and to investigate the correlation between these features and EPO treatment efficacy.

ResultsOur results revealed statistical significance in the top 3 ~ 15 most abundant joint distributions of Vβ-Jβ among the two groups, suggesting the importance of V or J gene utilization in the EPO response of ESRD patients.

ConclusionsIn summary, we provided evidence addressing the potential correlation between the immune repertoire and EPO response in ESRD patients.
