Osteoprotegerin (OPG), receptor activator of NF-κB ligand (RANKL), and parathyroid hormone (PTH) play a central role in the regulation of bone turnover in chronic kidney disease (CKD), but their influence on bone mineral density (BMD) and strength remains unclear, particularly in children. We studied the clinical significance of OPG and RANKL in relation to PTH, femur weight, BMD, and bone biomechanical properties in growing rats after one month (CKD-1) and three months (CKD-3) of surgically-induced mild CKD...

SHPT is one of the most common complications of CKD-MBD. Recent studies indicate that oxyphil cell proliferation is related to SHPT progression, while not inhibited by current treatments. The aim of this study was to analysis the correlation between oxyphil cell and clinical indicators in SHPT, further explore the protein expression differences of oxyphil cell. Among 33 MHD patients, 84.8% patients have one or more oxyphil dominant glands and the overall oxyphil cells proportion was 39.5 ± 16.3%. Univariate correlation and multivariable linear regression analyze showed that oral calcitriol dose and treatment duration were independent indicators of oxyphil cell ratio...

Uremic encephalopathy is a severe complication of renal failure. The underlying pathogenesis is unknown although several mechanisms have been suggested. Renal failure causes oxidative stress leading to cardiovascular complications. It has been suggested as the potential mediator of uremic encephalopathy as well, but it is largely unknown whether brain tissue itself undergoes oxidative damage in uremia. The aim of our experiment was to analyze oxidative stress markers in different brain regions in an animal model of acute kidney injury (AKI)...

Patients with advanced chronic kidney disease exhibit an increase in cardiovascular mortality. Recent works have shown that low levels of magnesium are associated with increased cardiovascular and all-cause mortality in hemodialysis patients. Epidemiological studies suggest an influence of low levels of magnesium on the occurrence of cardiovascular disease, which is also observed in the normal population. Magnesium is involved in critical cellular events such as apoptosis and oxidative stress. It also participates in a number of enzymatic reactions...

Urea was identified as a urinary salt in 1662 and was the first organic bodily product to be synthesized in vitro in 1828. This heralded the end of an era that defined disease as an imbalance between vital life forces, and catalyzed the merging of organic chemical sciences into clinical medicine. The term urée (urea) was introduced in 1803, its accumulation in blood was dubbed urémie (uremia) in 1847, and the procedure for its removal from urine across semi-permeable membranes designated dialysis in 1861...

Chronic kidney disease (CKD) is associated with an imbalanced human microbiome due not only to CKD-associated factors such as uremia, increased inflammation and immunosuppression, but also to pharmacological therapies and dietary restrictions. End-stage renal disease patients require renal replacement therapies commonly in the form of hemodialysis (HD) or peritoneal dialysis (PD). HD implies the existence of a vascular access, such as an arteriovenous fistula/graft or a venous catheter, whereas PD implies a long-term peritoneal catheter and the constant inflow of peritoneal dialysate...

Oxidative stress plays a key role in the pathophysiological process of uremia and its complications, particularly in cardiovascular disease. The level of oxidative stress markers is known to increase as chronic kidney disease progresses and correlates significantly with the level of renal function. Hemodialysis and peritoneal dialysis are major modes of renal replacement therapy for end-stage renal disease patients, but unfortunately they are also accompanied by increased oxidative stress. Successful kidney transplantation, however, results in near normalization of the antioxidant status and lipid metabolism by eliminating free radicals despite the surge of oxidative stress caused by the surgical procedure and ischemic injury to the organ during the operation...

OBJECTIVE: Despite advances in prevention of inflammatory milieu with different anti-inflammatory modalities in hemodialysis patients the rate of inflammatory markers in this population are still high. Inflammation is considered as a major player in uremia associated with morbidity and mortality in hemodialysis patients. The aim of this study was to evaluate the turmeric s effects on reduction of inflammatory markers in hemodialysis patients. METHODS: Hemodialysis patients over 18 years were recruited after fulfilling the inclusion criteria...

BACKGROUND: Restless legs syndrome (RLS) is a common complication of uremia that may improve after transplantation. Its frequency might not be as low as expected, as some uremic disturbances may continue even after a successful graft. Our aim was to investigate the prevalence and related conditions for RLS in renal transplant patients. METHODS: We carried out a cross-sectional, observational study. A self-administered questionnaire following the International Restless Legs Syndrome Study Group diagnostic criteria was administered to 129 patients (82 men and 47 women) aged 57 ± 12...

Hyperphosphatemia is a common condition in patients with chronic kidney disease (CKD) and can lead to bone disease, vascular calcification, and increased risks of cardiovascular disease and mortality. Inorganic phosphate (Pi) is absorbed in the intestine, an important step in the maintenance of homeostasis. In CKD, it is not clear to what extent Pi absorption is modulated by dietary Pi. Thus, we investigated 5/6 nephrectomized (Nx) Wistar rats to test whether acute variations in dietary Pi concentration over 2 days would alter hormones involved in Pi metabolism, expression of sodium-phosphate cotransporters, apoptosis, and the expression of matrix extracellular phosphoglycoprotein (MEPE) in different segments of the small intestine...

Inter-organ crosstalk plays an essential role in the physiological homeostasis of the heart and other organs, and requires a complex interaction between a host of cellular, molecular, and neural factors. Derangements in these interactions can initiate multi-organ dysfunction. This is the case, for instance, in the heart or kidneys where a pathological alteration in one organ can unfavorably affect function in another distant organ; attention is currently being paid to understanding the physiopathological consequences of kidney dysfunction on cardiac performance that lead to cardiorenal syndrome...
