Whether uric acid (UA)-lowering therapy (ULT) is effective in reducing the progression of renal dysfunction in patients with chronic kidney disease (CKD) remains controversial. Since several advances have been made in therapies for hyperuricemia, including novel xanthine oxidoreductase (XOR) inhibitors, we conducted a systematic review to clarify the effectiveness of ULT in preserving renal function among CKD patients. In this systematic review, the MEDLINE database was searched up to June 2019....

Anemia treatment is crucial in the management of dialyzed patients. Although Hb and serum ferritin levels are commonly used as indicators for treatment, these values change over time due to changes in policy, drugs for treating anemia, and target levels suggested by clinical guidelines. To clarify long-term changes in anemia-related parameters in Japan, we extracted annual patient data from a newly developed web-based system by the Japanese Society for Dialysis Therapy, the Web-based Analysis of...

The aim of this study was to compare the changes in peritoneal function and residual renal function in the first year between diabetic and non-diabetic patients receiving peritoneal dialysis (PD). We extracted 73 incident PD patients (male, 73%; age, 59 ± 15 years) from a previous cohort, and investigated the changes in PD-related parameters, including the dialysate to plasma ratio of creatinine (D/P Cr) and Kt/V. D/P Cr increased in non-diabetics, whereas it did not change significantly in diab...

Background:Unlike the situation in the general population, most studies of patients receiving hemodialysis have reported lower uric acid (UA) as associated with higher mortality. However, the relat...

BACKGROUND Although zinc deficiency is common among dialyzed patients, its prevalence among non-dialyzed subjects and its relationship to renal function remain unclear. METHODS We selected 816 non-dialyzed subjects (495 males; mean age, 56 ± 18 years) who underwent measurement of serum zinc at Jikei University Hospital between April 2018 and March 2019 using the Standardized Structured Medical Information eXchange2 (SS-MIX2) system, a global standard in Japan that enables collection of structure...

The traditional anion gap (AG) equation is widely used, but its misdiagnosis in end-stage kidney disease (ESKD) patients has not been investigated fully. Diagnostic accuracy to detect high AG was cross-sectionally evaluated using 3 AG equations in 1733 ESKD patients with an eGFR less than 15 mL/min/1.73 m2. The prevalence of high AG was 67.9%, 92.1% and 97.4% by the traditional, albumin-adjusted AG (aAG) and full AG equations, respectively. The sensitivity, specificity, accuracy and Kappa coeffi...

Background Fatigue is one of the most frequent complications in dialyzed patients and is associated with poorer patient outcomes. Multiple factors are reported to be associated with fatigue development. Of them, the impacts of dialysis modalities remain unknown. Methods A total of 194 dialysis patients (mean age, 61±11 years; 134 males; modalities included hemodialysis (HD) in 26, online hemodiafiltration (HDF) in 74, peritoneal dialysis (PD) in 68, and combined therapy with PD and HD in 26 case...

BACKGROUND The prevalence and severity of anemia differ between diabetic and non-diabetic patients. We investigated whether the effect of hemoglobin (Hb) on patient outcome was affected by the presence or absence of diabetes among Japanese patients receiving chronic hemodialysis (HD). METHODS We enrolled 149,308 patients from a nationwide dialysis registry in Japan at the end of 2012 (mean age, 67.6 ± 12.3 years; male, 61.7%; diabetes, 43.5%; median dialysis duration, 65 months) who underwent th...
