Filter by:Studying whether Klotho and FGF23 have a role in UP and whether their expression change by BB-UVB with the improvement of pruritus.
Salt (NaCl) intake is implicated in causing hypertension and cardiovascular disease, the commonest cause of death worldwide. The investigators recently established that Na+ is stored in tissues, bound to glycosaminoglycans (GAGs) in skin and muscle. The resulting local hypertonicity leads to immune cell-driven induction of local tissue electrolyte clearance via modulation of cutaneous lymph capillary density. To visualize these complex processes in man directly, the investigators established Na+ magnetic resonance imaging (23Na-MRI) and investigated Na+ stores in hemodialysis (HD) patients. Hemodialysis patients were sodium-"overloaded" and HD treatment lowered tissue Na+ stores in this study. The observed effects were highly variable and independent of Na+ or water removal from the body during a dialysis session. Tissue Na+ mobilization correlated with circulating vascular endothelial growth factor-C (VEGF-C). The investigators believe that excessive Na+ storage is a reversible condition and therefore susceptible for therapeutic interventions. The investigators hypothesize that lowering dialysate Na+ concentration may favorably affect accelerated tissue Na+ accumulation in hemodialysis patients. Besides, improved tissue Na+ storage, osmostress-induced as well as pro-inflammatory immune cell response should be affected by such a revised dialysis management.
Vascular calcification is a common finding in chronic kidney disease and increases arterial stiffness leading to augmented cardiovascular morbidity. The calcification process is thoroughly regulated by pro and anticalcifying agents. The investigators hypothesize that imbalance in these compounds could depend on alkaline phosphatase activity. Therefore, the investigators will measure ALP activity, calcifications score, arterial stiffness and perform a bio-collection in monogenic rare diseases characterized by various levels of anticalcifying agents and in diverse CKD stages characterized by various levels of procalcifying compounds.
The study will investigate the effects of an intradialytic resistance training on miRNA´s expression and muscle strength in haemodialysis patients.
This study will evaluate the cost-effectiveness of unplanned dialysis (peritoneal dialysis and hemodialysis) in chronic kidney disease (CKD) during the first year of therapy in a single center.
Hyperphosphatemia is a severe complication to chronic kidney disease (CKD) and is associated with increased risk of vascular calcification, cardiovascular morbidity and mortality. Early dietary intervention and improvement in dietary therapy might optimally reduce cardiovascular complications. For this purpose the investigators investigated patients with CKD stage 3-4, the participants dietary habits, developed a New Nordic Renal Diet and investigated the short term effect on phosphorus homeostasis.
Sevelamer hydrochloride (SE) can increase intestinal calcium absorption in contrast to lanthanum carbonate (LA). Study compared effect of LA and SE on serum and urine phosphate and calcium, and hormones regulating mineral-bone metabolism.
Recent studies have demonstrated that the balance of intestinal microbiota is affected in chronic kidney disease (CKD), leading to a condition known as intestinal dysbiosis. These changes were associated with metabolic complications, accumulation of uremic toxins, inflammation, progression of CKD and cardiovascular risk. Measures with the aim of restore the balance of intestinal flora are suggested, such as the intake of probiotics composed of beneficial bacteria, but few studies have discussed the effect of these supplements in CKD. The present study aims to evaluate the effect of consumption of probiotics in factors associates with progression of CKD and cardiovascular risk. To such will be conducted a double-blind, placebo-controlled, and randomized clinical trial with 30 patients with CKD in stages 3-5, treated in ambulatories of Nephrology of the Hospital de Clínicas de Porto Alegre, independently of etiology and with steady renal function. Patients will be excluded whether in substitutive renal therapy, kidney transplant, on antimicrobial therapy or immunosuppressive agents in the last three months or with acute clinical events. The assessment will include clinical and nutritional parameters, estimated glomerular filtration rate, proteinuria, serum lipids, inflammatory factors, and bowel habits. The study protocol includes the recruitment of patients who will undergo to 4-week washout period. After patients will be randomized and provided with probiotic therapy (intervention group) or placebo (maltodextrin; control group) for 24 weeks. All patients will be instructed to consume 2 sachets/day of probiotic or placebo and receive nutritional advice. All data will be analysed by the principal investigator with the support of a trained statistician and the chief investigator. The statistical programme SPSS will be used.
The goal of this study is to determine whether experiencing stress from discrimination may increase chronic kidney disease (CKD) progression in African Americans. Study participation occurs over the course of 2 days, and participant time burden is expected to be about 4.5 hours, plus a 24-hour period of wearing a blood pressure monitor.
The purpose of this study is to evaluate the impact of the optimal and late initiation of dialysis on the mortality and quality of life in end-stage renal disease (ESRD) patients by the Dialysis Initiation based on Fuzzy mathematics Equation (DIFE), which is a novel equation for the assessment of timing of dialysis initiation established by Fuzzy mathematics.
