Sarcopenia has become a serious disorder in modern society. Chronic kidney disease requiring dialysis and diabetes are some of the disorders that accelerate onset progression sarcopenia. We, therefore, investigated prevalence sarcopenia patients undergoing hemodialysis (HD) confirmed impact mellitus (DM) on this population. This study included 308 whose muscle strength mass had been evaluated using handgrip dual-energy X-ray absorptiometry, respectively. was defined according to criteria...

Treatment with sodium-glucose cotransporter-2 (SGLT2) inhibitors may have pleiotropic and beneficial effects in terms of ameliorating risk factors for the progression autosomal dominant polycystic kidney disease (ADPKD). However, there is insufficient evidence regarding use these drugs patients ADPKD, as they were excluded from several clinical trials conducted to explore protection provided by SGLT2 inhibitors. This retrospective single-arm case series study was performed investigate...

ABSTRACT Background Fetuin-A inhibits precipitation of calcium-phosphate crystals by forming calciprotein particles (CPP). A novel T50 test, which measures transformation time from primary to secondary CPP, is an index for calcification propensity. Both lower fetuin-A and shorter levels were associated with cardiovascular disease (CVD) risk in patients chronic kidney (CKD). Extremely high CVD death advanced CKD consists high-incidental event mortality after event. To date, it unclear whether...

Low thyroid function may be associated with a reduced glomerular filtration rate (GFR) calculated on the basis of creatinine metabolism. Thyroid hormone directly affects serum in muscle and low might exert similar direct effect kidney. The goal study was to evaluate this possibility by assessment inulin-based GFR examine mechanism underlying reduction GFR.Renal hemodynamics were assessed simultaneous measurements plasma clearance para-aminohippurate (CPAH) inulin (Cin) 26 patients <1.00...

OBJECTIVE Little is known about the relationships between insulin resistance, intrarenal hemodynamics, and urinary albumin excretion (UAE) in humans with impaired fasting glucose (IFG) and/or tolerance (IGT). The aim of current study was to examine hemodynamic abnormalities, UAE subjects IFG or IGT. We hypothesized that abnormalities would be associated resistance.

Fetuin-A, a circulating glycoprotein synthesized in the liver, is involved insulin resistance and type 2 diabetes. However, regulation of fetuin-A synthesis has remained obscure. We previously reported that pioglitazone treatment significantly reduced serum levels patients with To clarify whether can directory inhibit hepatic synthesis, we investigated effects on expression both vitro vivo. Pioglitazone suppressed mRNA protein Fao hepatoma cells. Interestingly, rosiglitazone but not...

Hyperuricemia has been reported to affect renal hemodynamics. In a recent study, both low and high levels of serum uric acid (SUA) were found be associated with loss kidney function. The goal this study was evaluate the relationship between SUA intrarenal hemodynamic parameters in healthy subjects, using plasma clearance para-aminohippurate (CPAH) inulin (Cin). Renal glomerular hemodynamics evaluated by simultaneous measurements CPAH Cin 48 subjects (54.6 ± 13.4 yr). Intrarenal parameters,...

Aim: Both oxidative stress and inflammation are involved in the pathogenesis of cardiovascular disease (CVD). The serum level derivatives reactive oxygen metabolites (d-ROMs) is a measure total amount hydroperoxides serving as marker stress. We investigated whether d-ROMs could predict clinical outcomes hemodialysis patients associations with independent inflammation, C-reactive protein (CRP).

Background and objectives Vitamin D receptor activators calcimimetics (calcium-sensing agonists) are two major options for medical treatment of secondary hyperparathyroidism. A higher serum calcification propensity (a shorter T 50 value) is a novel surrogate marker stress mortality in patients with CKD. We tested hypothesis that calcimimetic agent etelcalcetide more effective increasing value than vitamin activator maxacalcitol. Design, setting, participants, &amp; measurements randomized,...

OBJECTIVE Serum creatinine levels are lower in diabetic patients compared with their nondiabetic counterparts. Therefore, estimated glomerular filtration rate (eGFR) is higher the former than latter group. Factors associated overestimation of renal function were examined, and new formulae reflecting precise eGFR created. RESEARCH DESIGN AND METHODS Eighty subjects (age 56.5 ± 15.4 years; 35 males [43.8%]; 40 diabetes subjects) enrolled. GFR was evaluated by inulin clearance (Cin). values...

Xanthine oxidoreductase activity (XOR-a) plays an important role as a pivotal source of reactive oxygen species. In the present study, we investigated factors associated with plasma XOR-a in 163 hemodialysis patients (age 67.3 ± 10.9 years; 89 males and 74 females), using newly established, highly-sensitive assay based on [13C2,15N2] xanthine liquid chromatography/triple quadrupole mass spectrometry. Plasma glucose serum uric acid levels correlated significantly positively XOR-a. multiple...
