Active clinical trials for "Diabetic Nephropathies"

Diabetes mellitus is a chronic disease that affects 366 million people worldwide ( 6.4 % of the adult population ) and is expected to rise to 522 million by 2030 . Diabetic nephropathy occurs in approximately one - third of all people with diabetes and is the leading cause of renal failure in developed and developing countries Diabetic nephropathy is a severe complication occurring in diabetic patients and it is associated with an increased risk of all- cause mortality , cardiovascular disease and progression to end stage renal disease , requiring costly renal replacement therapy in the form of dialysis or transplantation

Background: Diabetic kidney disease (DKD), as one of chronic complication of type 2 diabetes mellitus, is common cause of end stage renal disease (ESRD). Vitamin D deficiency is known as one of DKD risk factors. Recent studies on association between vitamin D deficiency and DKD had shown conflicting results. It may be due to vitamin D receptor gene polymorphisms, which is affected by BsmI, Cdx2, ApaI, FokI, and TaqI gene. The investigators conducted cross-sectional study to investigate association between BsmI polymorphisms in vitamin D receptor gene with diabetic kidney disease Hypothesis: BsmI polymorphisms in vitamin D receptor gene is associated with diabetic kidney disease (DKD)

Diabetic kidney disease is a common complication of diabetes and the main cause of end-stage renal disease. In this study, the investigator plan to enroll nearly 500 participant with/without DKD and to develop an automatic segmentation ultrasound based radiomics technology to differentiating participant with a non-invasive and an available way.

The physiopathology of diabetic nephropathy (DN) is unclear. To investigate risk factor, the investigators choose to look about some oxidative stress genes. Today a one-gene explanation is not really possible. So the theory of some genetic predisposition to DN is more likely. The aim of the study is to look about the association of the C282T polymorphism of P22phox, a sub unit of the nicotinamide adenine dinucleotide phosphate-oxidase (NADPH oxidase) in the occurrence of DN. To follow the oxidative stress pathway of the DN, the investigators also investigate three other polymorphisms: -429 T/C, -374 T/A polymorphism of advanced glycation end-products receptor (AGER) and the p.Arg261Gln polymorphism of the 12 lipoxygenase (ALOX 12). Discordant data suggest a link between the first 2 polymorphisms and DN. The last polymorphism is correlated to albuminuria in diabetic patients.

This study aims to observe changes in various indicators of renal function, such as proteinuria at different time points: short-term (Week 8), 6 months (Week 26), and a year (Week 52), in patients with DKD and hypertension, who are given antihypertensives containing fimasartan, in an actual clinical environment where a variety of patient characteristics are reflected.

The main purpose of this study is to analyse test-retest-reliability of functional quantification of endothelial dysfunction through puls-amplitude-tonometry in patients with heart failure with preserved/reduced ejection fraction, pulmonary hypertension, arterial hypertension and diabetic nephropathy. In the same group, test-retest-reliability of circulating endothelial cells as well as test-retest reliability of non invasive cardiac output Monitoring will be observed and analysed.

Background The prevalence and incidence of type 2 diabetes is increasing globally. A common complication of diabetes is the disease of the blood vessels, vascular diseases, which can cause disorders like myocardial infarction, stroke and kidney failure. Methods to detect early subclinical stages of macro-vascular disease are not yet available in a clinical setting. Hypothesis Arterial stiffness, an easy accessible vascular parameter, may provide additional prognostic information when evaluating risk profile for patients with diabetes type 2. Aim The aim of the project is to investigate the association between arterial stiffness and the occurrence and development of vascular complications in patients with type 2 diabetes. Specifically we want to investigate: in a cross-sectional study, the association between arterial stiffness and subclinical atherosclerotic changes in the coronary arteries assessed by computed tomography (CT) and in a longitudinal study, the predictive value of arterial stiffness on the development of subclinical cerebrovascular changes assessed by magnetic resonance imaging (MRI) and nephropathy assessed by urine analysis. Methods The study population consists of 100 patients with newly diagnosed type 2 diabetes and 100 age- and sex matched controls. The study participants were enrolled between 2008-2011 and extensively characterized i.a. with arterial stiffness (pulse wave velocity), MRI (white matter lesions and cerebral infarctions) and urine analysis (albuminuria). In this study we will enrol the same patients in a 5 year follow-up study in order to repeat above mentioned measurements. Furthermore, CT is used to investigate the coronary plaque burden of the participants (Agatston Score and Segment Involvement Score). Results and Perspective This project adds new insight into arterial stiffness as a predictor of the progression of micro- and macrovascular complications in patients with type 2 diabetes, and can potentially improve risk stratification and early strategies of intervention in this patient group.

The Family Investigation of Nephropathy and Diabetes (FIND)Study is a multi-center consortium. The charge of the consortium is to acquire sets of families with well-characterized diabetic nephropathy, establish a secure master FIND database, and perform a genome scan to identify chromosomal regions linked with diabetic nephropathy.

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.
