Association between physical activity and decline in renal function among the general population is not fully understood. This is a longitudinal study on subjects who participated in the Japanese nationwide Specific Health Checkup program between 2008 and 2014. The exposure of interest was baseline self-reported walking habit. The outcomes were annual change and incidence of 30% decline in estimated glomerular filtration rate (eGFR). Changes in eGFR were compared using a linear mixed-effects mod...

Factors affecting decline in renal function and cyst growth in patients with autosomal polycystic kidney disease (ADPKD) are not fully described, particularly in Japan. This was the first multi-facility, prospective, observational cohort study conducted in ADPKD patients at 14 centers in Japan. Patients in the J-PKD registry were assessed from December 2009 to June 2012 (follow-up until June 2017). Patients’ data including estimated glomerular filtration rate (eGFR) and total kidney volume (TKV)...

BACKGROUND Disease-specific trajectories of renal function in advanced chronic kidney disease (CKD) are not well defined. Here, we compared these trajectories in the estimated glomerular filtration rate (eGFR) by CKD stages. METHODS Patients with multiple eGFR measurements during the 5-year preregistration period of the REACH-J study were enrolled. Mean annual eGFR declines were calculated from linear mixed effect models with the adjustment variables of baseline CKD stage, age, sex and the curre...

Antiribosomal P protein (anti-P) autoantibodies commonly develop in patients with systemic lupus erythematosus. We have previously established hybridoma clones producing anti-P mAbs. In this study, we explored the pathogenesis of behavioral disorders induced by anti-P Abs using these mAbs. New Zealand Black × New Zealand White F1, New Zealand White, C57BL/6, and BALB/c mice were treated with 1 mg of anti-P Abs once every 2 wk. The behavioral disorder was evaluated by the tail suspension test, fo...

Objectives Chronic kidney disease (CKD) is a significant public health problem. An advanced, or innovative, CKD care system of clinical practice collaboration among general physicians (GPs), nephrologists, and other healthcare workers achieved behavior modification in patients with Stage 3 CKD in the Frontier of Renal Outcome Modifications in Japan (FROM-J) study. This behavior modification intervention consisted of educational sessions on nutrition and lifestyle, as well as encouragement of pat...

Objective Despite advances in medicine, aortic diseases (ADs), such as aneurysm rupture and aortic dissection, remain fatal and carry extremely high mortality rates. Due to its low frequency, the risk of developing AD has not yet been fully elucidated. Chronic kidney disease (CKD) is an established risk factor for cardiovascular disease and mortality. The aim of the present study was to examine whether or not CKD is a risk for AD-related mortality in the general population. Methods We used a nat...

Angiotensin-converting enzyme inhibitors (ACEIs) and angiotensin receptor blockers (ARBs) are prescribed as conservative or adjunctive therapies for adult idiopathic nephrotic syndrome. However, studies on real-world practice patterns are scarce. This study aimed to examine the prevalence and incidence of ACEI/ARB prescription and their associated factors. This nationwide cohort study included adult Japanese patients with idiopathic nephrotic syndrome including minimal change disease (MCD), memb...

Background Our aim was to assess how the population-attributable fraction (PAF) for premature mortality due to cardiovascular disease (CVD) associated with hypertension changes if blood pressure (BP) thresholds for hypertension were lowered from systolic /diastolic BP ≥140/90 mm Hg to ≥130/80 mm Hg, as defined using the 2017 American College of Cardiology/American Heart Association blood pressure guideline. Methods Analyses were conducted using a database of participants who underwent a national...
