Active clinical trials for "Kidney Diseases"

Chronic kidney disease has become an important Public Health issue in most developed and developing countries, with increasing incidence and prevalence rates. The cost associated with chronic kidney disease patients is very high, derived from renal replacement therapy and the cost associated with the high cardiovascular risk of this population. Primary and secondary preventive measures are imperative. In this sense, the comprehension of mechanisms and biomarkers associated with CKD progression and mortality risk in this population is an important area of research. Cohort studies are important tools for testing risk factors and biomarkers. Currently, CKD cohorts, particularly of those not on dialysis, are few and restricted to North America and Europe. The present study established a cohort of 454 CKD participants (not on dialysis) in Sao Paulo, Brazil, who will be followed for 7-10 years. Baseline data collection was wide, including medical history, diet (food frequency questionnaire), calcium score, echocardiography, pulse wave velocity, cardiac frequency variability, carotid intimal media thickness, retinography, and an extensive biobank. Follow-up is ongoing and made through annual telephone interviews including questions on death, hospitalizations, and need of renal replacement therapy (RRT). Vital status is investigated periodically by a hot-pursuit strategy.

After administration of intravascular iodinated contrast media Contrast-Induced Nephropathy (CIN), also known as Contrast-Induced Acute Kidney Injury (CIAKI), may occur. CIN/CI-AKI is associated with increased risk of dialysis and mortality. No treatment exists for CIN/CI-AKI, therefore the focus lies on prevention. Clinical practice guidelines for the prevention of CIN/CI-AKI exist and are implemented in most hospitals. Generally, intravascular volume expansion with normal saline is recommended as prophylaxis. Earlier this year the results of the AMACING study (A MAastricht Contrast-Induced Nephropathy Guideline study) were published in The Lancet (NL47173.068.14/METC 14-2-006; Clinical Trials.gov NCT02106234; http://www.thelancet.com/journals/lancet/article/PIIS0140-6736(17)30057-0/fulltext). These results show that for the greater part (>90%) of patients considered to be at risk of CIN/CI-AKI by the guidelines, withholding prophylaxis is non-inferior to giving standard intravenous prophylactic hydration in the prevention of CIN/CI-AKI. Furthermore, the standard prophylactic hydration confers some risk (5.5% complications of intravenous hydration were recorded in the AMACING study). As a result the clinical protocol in the Maastricht University Medical Centre (MUMC+) has been adapted, and patients with an estimated Glomerular Filtration Rate (eGFR) >29mL/min/1.73m2 no longer receive intravenous prophylactic hydration before or after procedures with intravascular iodinated contrast material administration. CINART is a one year prospective observational study with the aim to evaluate the consequences of the protocol change for 1. for incidences of CIN/CI-AKI, dialysis and mortality, 2. for clinical practice in terms of patient burden (complications of prophylaxis), hospital burden (extra hospitalisations for prophylaxis), and costs, as derived from the number of elective procedures carried out in patients formerly eligible for prophylaxis.

The purpose of this study is to collect genomic and clinical data among a cohort of hemodialysis patients and analyze the association between genetic markers and the development and severity of illness in response to SARS-CoV-2.

The Automatic Tongue Diagnosis System (ATDS) was developed to capture tongue images and extract features reliably to assist the diagnosis of traditional chinese medicine (TCM) practitioners.This project will employ the ATDS verified to extract the tongue features of patients with chronic kidney disease. A TCM indices derived through the non-intrusive tongue diagnosis procedure can provide valuable information for clinical doctors to analyze the current status of a patient and dynamically schedule a treatment plan, facilitating early detection and diagnosis of chronic kidney disease.

This is a prospective, clinical, multicentre study aimed to collect biological samples and study microbiota from subjects suffering from chronic kidney disease and from healthy volunteers. Microbiota is a complex consortium of microorganisms, located at the mucosal level (in particular intestinal, oral and vaginal) having a key role in human health and in the onset of several diseases. Microbiota alterations have been found in several diseases (gastrointestinal, metabolic, renal, oncological, gynaecological). The study will allow to: Provide biological samples (faeces, saliva, blood, urine) from healthy volunteers and patients suffering from chronic renal diseases to the first Italian microbiota biobank; Study microorganisms using different in vitro and in vivo techniques; Study the link between the microbiota and the disease. This study is part of the BIOMIS project (Project Code: ARS01_01220), presented as part of the "Avviso per la presentazione di progetti di ricerca industriale e sviluppo sperimentale nelle 12 aree di specializzazione individuate dal PNR 2015-2020" and admitted to funding under the National Operational Program "Ricerca e Innovazione" 2014-2020 by directorial decree of MIUR - Department for Higher Education and Research - n. 2298 of 12 September 2018. BIOMIS includes several clinical studies that enrol patients with different pathologies to collect and store biological samples and study microbiota.

The Investigators will generate a repository of human biosamples across therapeutic areas that will be used to identify disease-associated biomarkers and potential targets with immune and multi-omics profiling. This sample collection and analysis from people living with type 2 diabetes, or chronic or diabetic kidney disease will lay the groundwork for an extensive network of biosample access and linked datasets that will provide an invaluable resource for translational research.

This is a cohort study in which patients who survive Acute Kidney Injury (AKI) during intensive care unit (ICU) admission are recalled at 3-6 months and renal function tests are performed. The purpose of the study is describe renal function in AKI survivors at follow-up. Additional aims are to determine how well admission values of renal function markers perform as predictors of renal function at follow-up and whether estimates of renal function at follow-up differ depending on which renal function marker is used.

The main purpose for holding this survey is epidemiological surveillance, it must provide the indicators that contribute to the evaluation of the plan "improvement of the quality of life in chronic diseases" and monitoring the goal of 81 health law public in August 2004. This survey is intended to be renewed during the implementation period of the public health law to provide plan monitoring indicators. The main objective is : To describe the quality of life of patients with major end-stage renal disease treated with dialysis method for at least one year. The seconds objectives are : To contribute to the knowledge of the key determinants of the quality of life among chronic renal failure patients. To study the influence on way of giving a questionnaire about assessment of level of quality of life

Patients with sickle cell disease may be at risk for acute kidney injury (AKI)during sickle cell crisis (pain or acute chest syndrome). This study will evaluate the role of hemolysis during SCD crisis on the development of AKI and the role for monitoring urine biomarkers during an admission for crisis and during well clinic follow-up.

The aim of this study is to evaluate the prevalence of secondary hyperparathyroidism among patients with diabetic nephropathy.
