TL;DR: In this paper, the authors used the modified isotope dilution mass spectrometry (IDMS)-traceable 4-variable modified modification of Diet in Renal Disease (MDRD) study equation to estimate the glomerular filtration rate (GFR) for Japanese patients.

TL;DR: Although the Japanese coefficient improves the accuracy of G FR estimation of the original MDRD study equation, a new equation is needed for more accurate estimation of GFR in Japanese patients with CKD stages 3 and 4.

TL;DR: The number of patients who underwent hemodiafiltration (HDF) at the end of 2013 was 31 371, a marked increase from that in 2012, and the number of Patients who underwent online HDF increased approximately fivefold over the last 2 years.
Journal ArticleDOI

TL;DR: GFR estimates using the IDMS MDRD Study equation with the JSN-CKDI coefficient or the new JSN (JSN)KDI equation are more accurate than the IDM (MDRD) Study equation in hospitalized Japanese patients with eGFR less than 60 mL/min/1.73 m(2).
Journal ArticleDOI

TL;DR: About 20% of the Japanese adult population are predicted to have stage 3 to 5 CKD, as defined by a GFR of less than 60 ml/min per 1.73 m2, and the prevalence of concurrent CKD was significantly higher in hypertensive and diabetic populations than in the study population overall.
