Active clinical trials for "Kidney Diseases"

The objective of this study was to assess the effect of oral nutritional supplementation (ONS) combined with bioelectrical vector analysis (BIVA) on the nutritional and hydration status and the quality of life (QoL) in hemodialysis (HD) patients. Design and Methods: Thirty-two chronic HD patients were included in a 6-month randomized pilot study. Patients in SUPL group received a simultaneous intervention consisting of a personalized diet, 245 mL/d ONS and dry weight adjustment through BIVA. Patients in CON group received a personalized diet and dry weight adjustment by BIVA. Anthropometrical, biochemical, dietary, QoL, handgrip strength (HGS) and bioimpedance measurements were performed. Malnutrition Inflammation Score (MIS) was applied.

The purpose of this study is to characterize the effects of 85 days treatment with MLN1202 on urinary albumin-to-creatinine ratio (UACR) in participants with type 2 diabetes, advanced kidney disease/diabetic nephropathy (DN) and macro-albuminuria (UACR>300 mg/g) based on average of 3 consecutive first morning voids sample collection.

There is a pressing need to find effective strategies for the prevention of contrast induced nephropathy in patients with advanced renal dysfunction. The current study was designed to assess the efficacy of a new protocol for preventing contrast induced nephropathy in patients with advanced renal dysfunction undergoing coronary interventions

The purpose of this pilot study is to evaluate 1) the effect of intradialytic pedaling exercise on arterial stiffness and other arterial hemodynamic parameters over 4 months, and 2) the longer-term effect of pedaling on arterial stiffness and other arterial hemodynamic parameters 4 months after finishing the exercise intervention (8 months after study initiation). The investigators also aim to examine the impact of intradialytic pedaling exercise on general health, anthropometric measures, physical function, and routine laboratory blood markers as secondary outcome measures, as well as to assess feasibility, safety and adverse events associated with the intradialytic pedalling exercise. Recruitment of more participants in the future will be considered if warranted.

The key objective of this pilot study is to assess the molecular mechanisms of renal pre-conditioning by a one-week low-calorie diet in humans. The protective effect of the low-calorie diet and also of the protein-restriction in donor on transplant qualities and functions in receptor will also be investigated. Analysis of transcriptome, lipidome, metabolome, epigenome, proteome und phosphoproteome through tissue samples as well as blood samples for comparison of low-calorie diet, protein-restriction and no-diet groups.

The purpose of this research study is to determine the effect of a bicarbonate supplement on kidney function and physical function.

Background: Poor flow (PF) and catheter-related blood stream infections (CRBSI) are highly prevalent among CKD 5D patients with long-term central venous catheters. Heparin (H) catheter lock solutions are commonly used to maintain catheter patency, however PF and CRBSI incidence remains high. The purpose of this study was to evaluate two lock solutions on reduction of PF and CRBSI: one, a lock solution combining of the tetracycline antibiotic minocycline with the anticoagulant/chelation agent EDTA (M-EDTA) versus H; and other, trisodium citrate (C) versus H. M-EDTA and C were also evaluated as to their safety versus H. Methods:As regards the pilot project, thirty CKD 5D patients on high-efficiency hemodialysis (blood flow rate = 350 ml/min) at the Integrated Centre of Nephrology (Guarulhos, Brazil) were randomized 1:1:1 to receive M-EDTA, C or H locks for 15 weeks. Lock solutions concentrations were M-EDTA 30 mg/ml/3 mg/ml, C 30% (C) and H 1,000 U/ml and both investigators and patients were blinded to treatment allocation. The primary end-point was a 10% reduction in HD blood flow rates (35ml). The frequency of CRBSI was recorded. Bleeding and lock solution-related adverse events were the primary safety end points. Logistic Regression was performed to evaluate differences in PF rates among the treatments (SPSS version 13.0, IBM, USA). Based upon the pilot-study data, the clinical trials has being executed in order to verify whether the three lock solutions have the same performance or not.

The proposed randomized controlled trial will test the effect of dietary sodium reduction on albuminuria in patients with proteinuric chronic kidney disease. Results from this study will clarify the role of dietary sodium reduction in management of patients with proteinuric chronic kidney disease and its potential to halt the progression of chronic kidney disease.

Autosomal dominant polycystic kidney disease (ADPKD) is the most common monogenic hereditary kidney disease in humans. ADPKD may affect all the generations of the ADPKD family and the probability of ADPKD is 50% in the second generation for each gender. It has been confirmed that PKD1 and PKD2 are two pathogenic genes of ADPKD. Nowadays, the investigators have established an effective gene detection technology platform for PKD1/2 gene with long fragment PCR and next generation sequencing. First, the investigators performed genetic testing in patients with clinically diagnosed ADPKD and strong fertility desire, but afraid of hereditary risk. Using Preimplantation genetic diagnosis, including multiple annealing and looping-based amplification cycles amplification technique, the investigators successfully screened out healthy embryos by In Vitro Fertilization. Then the investigators transplanted embryos returned to the parent. When the baby is born, using umbilical cord blood gene detection, the investigators confirmed that the neonates do not inherit genetic defects form parents. The investigators have succeeded in one couple. The investigators design a multicenter clinical trial to confirm those procedures efficacy and safety.

To explore the efficacy of Ivabradine for the treatment of microalbuminuria in patients with type 2 diabetes and coronary heart disease.
