Response to erythropoietin in pediatric patients with chronic kidney disease: insights from an in vitro bioassay

ConclusionsOur findings support the presence of erythropoiesis inhibitory substances in uremic sera. EPO/EPO-R-dependent mechanisms may play a role in inhibiting erythropoiesis. The in vitro bioassay described herein may serve as an indicator of rHuEPO responsiveness which may encourage further investigation of underlying mechanisms of EPO resistance.

AbstractThe serum levels of hepcidin generally increase in patients with chronic kidney disease (CKD) due to inflammation or a decline in the glomerular filtration rate. However, the differences in the ferrokinetics among dialysis modalities are unclear. We investigated the relationship between serum levels of hepcidin and ferritin among non ‐dialyzed CKD (ND), hemodialysis (HD), and peritoneal dialysis (PD) patients. We recruited 285 CKD patients (117 ND, 80 HD, and 88 PD patients) and measured the serum levels of hepcidin‐25, ferritin, hemoglobin, iron, transferrin saturation (TSAT), albumin, and high sensitivity C...

Conclusions: TP0463518 induced dose-dependent EPO production, mainly derived from the liver in HV and CKD patients. These results suggest that TP0463518 is a new strategy for treating anemia in CKD, which can be used regardless of renal functions.Am J Nephrol 2018;48:157 –164

Authors: Zhang Y, Hu C, Bian Z, Chen P Abstract There are a lot of controversies pertaining to correctness of timing for the initiation of dialysis in chronic kidney disease (CKD) patients. The present study was conducted to examine the potential association of initiation timing of dialyses with long-term prognosis in CKD patients. In total, 294 patients confirmed as end-stage renal disease (ESRD) were included as study subjects. According to the estimated glomerular filtration rate (eGFR) at initiation time, the patients were classified into four groups based on eGFR: ≥10.5, 8-10.4, 6-8 and

Authors: Tsuruya K, Yoshida H Abstract BACKGROUND: There is an increasing prevalence of dementia associated with population aging, and anti-dementia measures have now become of increasing importance in Japan. Chronic kidney disease (CKD) is a risk factor for cognitive impairment. SUMMARY: We previously demonstrated that hemodialysis patients have a higher prevalence of brain atrophy, even at younger age, than the general population, and also demonstrated the association between frontal lobe atrophy and frequency of rapid decline in blood pressure during the hemodialysis session. Recently, we demonstrated that d...

Authors: Io H, Suzuki Y Abstract BACKGROUND: Currently, left ventricular (LV) hypertrophy and dysfunction are considered the strongest predictors of cardiovascular mortality in chronic kidney disease (CKD) patients. We investigated the factors associated with elevated LV mass index (LVMI) using echocardiography and assessed the strategies used to treat CKD (stages 1-5D) patients. SUMMARY: In study 1, we prospectively determined correlations among biochemical values, physical specimens, and LVMI using echocardiography in hemodialysis (HD) and peritoneal dialysis (PD) patients (stage 5D). In study 2, biochemical ...

CONCLUSIONS Anemia was more common in diabetic CKD patients. Diabetes mellitus was independently associated with iron deficiency. Surprisingly, diminished iron availability was not more frequent in diabetic patients. The physio-pathological mechanisms that could explain these findings remain to be elucidated.
