Active clinical trials for "Kidney Diseases"

Diabetes mellitus is one of the main causes of chronic kidney disease (CKD) and an increased risk of foot complications is seen in patients suffering from both DM and CKD. CKD and DM patients share a trilogy of risk factors that contribute to the development of foot ulcers. This trilogy consists of peripheral arterial disease (PAD), neuropathy and an increased susceptibility to infection with an impaired wound healing. Additionally, almost one quarter of adults with CKD have to cope with depression. The aim of our study is to determine the prevalence and types of foot problems in a pre-dialysis population, consisting of both DM and non-DM patients. If possible, risk factors will be determined. The detrimental effects of poor kidney function and foot problems on the quality of life and the general health status will be analyzed. A higher prevalence of PAD, peripheral neuropathy and DM are expected in patients with foot problems compared to those without.

The investigators plan to analyze the first year of a nationwide randomized-controlled trial of end stage renal disease (ESRD) treatment choice model (ETC). This mandatory-participation program was designed by the Centers for Medicare and Medicaid Services and randomization was conducted at the hospital referral region (HRR) level. 95 HRRs were assigned to the treatment group beginning in January 2021. The investigators will study the impact of this program in the first year on treatment modality choice for ESRD and explore heterogeneity in impact across patients and providers.

Autosomal dominant polycystic kidney disease (ADPKD) is the most common monogenic cause of end-stage kidney disease (ESKD). The disorder is characterized by development and continued growth of multiple cysts requiring renal replacement therapy in 50% of patients by age 60 years. However, ADPKD is also a complex metabolic disorder defined by insulin resistance (IR) and mitochondrial dysfunction which may be causally related to cyst expansion, kidney function decline and contribute to reduced life expectancy. Renal hypoxia, stemming from a potential metabolic mismatch between increased renal energy expenditure and impaired substrate utilization, is proposed as a novel unifying early pathway in the development and expansion of renal cysts in ADPKD. By examining the interplay between renal O2 consumption and energy utilization in young adults with and without ADPKD, the investigators hope to identify novel therapeutic targets to impede development of cyst expansion in future trials. The investigators propose to address the specific aims in a cross-sectional study with 20 adults with ADPKD (50% female, ages 18-40 years). Comparative data will be provided from healthy adults from an ongoing study with similar study design and methods (CROCODILE Study: Control of Renal Oxygen Consumption, Mitochondrial Dysfunction, and Insulin Resistance). For this protocol, participants will complete a one day study visit at Children's Hospital Colorado. Patients will undergo a dual energy x-ray absorptiometry (DXA) to assess body composition, and a 11C-acetate positron emission tomography (PET/CT) scan to quantify renal O2 consumption. After the PET/CT, participants will undergo a hyperinsulinemic-euglycemic clamp while fasting to quantify insulin sensitivity. Glomerular Filtration Rate (GFR) and Effective Renal Plasma Flow (ERPF) will be measured by iohexol and PAH clearances during the hyperinsulinemic-euglycemic clamp.

As a single center, retrospective observation study in Guangdong Institute of Cardiovascular Diseases, this study included the main study population of patients who underwent coronary angiography and / or coronary intervention from January 2007 to Decemeber 2018. The hospitalization information was collected in the form of direct derivation of the case, and cardiac and renal adverse events were collected through outpatient recorder system. All-cause death information was obtained from the Public Security and matched to the electronic Clinical Management System of the Guangdong Provincial People's Hospital records.

In this pilot study the investigator will examine the levels of fibroblast growth factor (FGF-23) and parathyroid hormone (PTH) levels during hemodialysis therapy in 30 patients and assess the correlation between these parameters and the T-50 calcification propensity, as well as further parameters of secondary hyperparathyroidism (sHPT), like serum calcium (sCa), phosphate (P), 25-hydroxy-vitamin D (25(OH)D) and 1,25 dihydroxy-vitamin D (1,25(OH)2D). The investigator hypothesize that FGF-23 and PTH levels are at their highest at the beginning of dialysis and decrease during the treatment.

This is a phase I, and II, single-center, open-label clinical trial to evaluate the safety and preliminary efficacy information of AminoMedix™ in protecting kidneys from radiation-induced toxicity during Peptide Receptor Radionuclide Therapy (PRRT) with 177Lu-DOTATATE in patients with neuroendocrine cancers. Aims of the study: Evaluation of the safety of AminoMedix ™ infusion. Evaluation of kidney radiation dosimetry with and without AminoMedix™ using 68Ga-DOTATATE PET/CT imaging as a surrogate marker for 177Lu-DOTATATE. Evaluation of the safety and calculation of kidney and tumor radiation dosimetry after AminoMedix™ infusion with low dose 177Lu-DOTATATE in patients with neuroendocrine cancers.

This observational study aims to compare long-acting darbepoetin alpha versus short-acting epoetin alpha erythropoietin-stimulating agents in Egyptian hemodialysis patients. The main questions aim to answer are: What are the effectiveness and safety of long- acting versus short-acting erythropoietin-stimulating agents in Egyptian hemodialysis patients? What is the cost-effectiveness of long- acting versus short-acting erythropoietin-stimulating agents in Egyptian hemodialysis patients? Participants will be divided into 2 groups; epoetin alfa (short-acting ESA), Eprex group, and darbepoetin alfa (long-acting ESA), Aranesp group for six month study period.

The study was conducted to assess safety and immunogenicity of recombinant human erythropoietin (rhEPO) manufactured by Daewoong Pharmaceutical Co., Ltd was similar to biological products approved by the drug safety regulatory authority.

This pilot study tests the feasibility of dietary app-supported tele-counseling in the treatment of patients with stage 1-3a chronic kidney disease (CKD) and diabetes.

Chronic kidney disease (CKD) is present in 1 in 7 of the population and confers a high risk of cardiovascular disease. The pathophysiology of cardiovascular disease in CKD is poorly understood because CKD is always accompanied by confounding factors including the underlying disease process (e.g. diabetes mellitus, systemic vasculitis) and the consequences of CKD including hypertension, anaemia and inflammation. Nephrectomy in kidney donors causes a 30% reduction in renal function providing an ideal study population to measure prospectively the effects of reduced kidney function on the cardiovascular system. The CRIB-Donor study (ClinicalTrials.gov Identifier:NCT01028703) demonstrated adverse effects on cardiovascular structure and function at 12 months compared to controls including an increase in left ventricular mass. This proposal will measure the changes in cardiovascular structure and function, cardiovascular age and biochemical changes at 5 years providing information on the long term effects of reduced renal function.
