Filter by:Dipeptidyl peptidase-4 (DPP-4) inhibitors improve glycemic control and contain pleiotropic actions on kidney injury, albuminuria and vascular inflammation especially in animal models. We plan to evaluate the efficacy of potent DPP4-inhibitors (gemigliptin) in response to these aspects in diabetic nephropathy patients.
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 primary objective is to assess the impact of three months' treatment with pre-/probiotic mix on markers of nephropathy and other comorbidity related to diabetes. A double blinded, randomized, placebo-controlled crossover, single-centre study including 46 patients with type 1 diabetes and albuminuria. The treatment period is 2 x 12 weeks with 6 weeks washout. The primary outcome is to evaluate the effect of pre-/probiotic mix on albuminuria.
Background: Diabetes, and especially diabetic kidney disease is associated with the development of cardiovascular disease such as calcification in the coronary arteries and heart failure. Sleep apnea is frequent among patients with diabetes and diabetic kidney disease and sleep apnea itself is a solitary risk factor in the development of cardiovascular disease. Nonetheless, sleep apnea is underdiagnosed in diabetes patients because of a discrepancy between sleep apnea severity and actual oxygen deficiency symptoms which makes the diagnosis difficult. For that reason, many diabetics have undiagnosed sleep apnea together with cardiovascular disease. Early discovery of sleep apnea among high risk diabetic patients may therefore be considered crucial before cardiovascular complications develop. For this reason, sleep apnea screening of high-risk diabetics can possibly improve early diagnostics of cardiovascular disease. Aim: This study will seek to establish the association between obstructive sleep apnea (OSA) and coronary calcification and heart failure in patients with diabetic kidney disease. The basic hypothesis of the study is that patients with diabetic kidney disease and concurrent OSA have a higher prevalence and severity of coronary calcification and heart failure compared to patients without OSA. Methods: Diabetic adult patients with scheduled check-ups at Steno Diabetes Center Aarhus, or Department of Renal Medicine on Aarhus University Hospital will be included in the study. Firstly, all included patients are screened for sleep apnea with the devices SomnoTouch® and ApneaLink®. Based on the sleep apnea determination; 40 patients with moderate-severe sleep apnea are compared with 40 patients without sleep apnea. In both groups, the patients are examined for calcification in the coronary vessels using a CT-scan while the function of the heart is examined by ultrasound (echocardiography). The stiffness of aorta is measured and performed using radial artery tonometry (SphygmoCor®). Furthermore, range of blood- and urine samples will be performed The perspectives are that patients with diabetes should be regularly evaluated for sleep apnea and that patients with moderate/severe sleep apnea should undergo further examination for cardiovascular disease even though the patients don't display any symptoms of either cardiovascular disease or sleep apnea.
This is a proof of concept (PoC) trial to evaluate the safety, tolerability and renal effect of APX-115 in subjects with Type 2 diabetes and nephropathy.
This phase 2a, double-blind, randomized, placebo-controlled study will assess the efficacy, safety, tolerability, and pharmacokinetics (PK), of repeat doses of CSL346 in subjects with diabetic kidney disease (DKD) and albuminuria receiving standard of care treatment.
Diabetic microangiopathy refers to the pathological changes of arterioles, capillaries and venules in diabetic patients. Due to the impacts including glycol-metabolism disorder, disturbance of lipid metabolism, cytokine, oxidative stress and hemodynamic changes, the structure and function of microvessels are damaged accordingly. Diabetic nephropathy (DN) is one of the most common and serious chronic microvascular complications of diabetes, and becomes a leading cause of end-stage renal failure(ESRF). Presently, urinary albumin/creatinine ratio (UACR) is a widely accepted and relatively reliable indicator for early diagnosis of DN, however, there are 2/3 DN patients with normal albuminuria have decreased glomerular filtration rate (glomerular filtration rate, GFR) and abnormal structure of the kidney, one the other hand, the presence of albuminuria is associated with other vascular dysfunction and kidney disease other than DN, therefore its accuracy is increasingly being challenged. Sidestream dark field(SDF) imagining technology, as an emerging way to visualize blood vessels, is evaluated in a semi-quantitative manner and provides an effective means to study structure and function of microcirculation. Different from biochemical markers like albuminuria, SDF provides a visual information about vessel structure, density, and quality of diffusion. At present the research of sublingual microcirculation by SDF technique is mainly applied to microcirculation monitoring in patients in the intensive care unit or laboratory animal models with acute hemorrhagic shock to assess the potential of being a tool of diagnosis and treatment prognostic indicator, no relevant research has been carried out to evaluate the predictive value of diabetic microangiopathy in literature so far. Herein, the investigators designed the study based on SDF imaging to collect scientific data, thus providing strong support for the early assessment and diagnosis of diabetic nephropathy and possibly guiding individual therapy in the future.
Diabetic nephropathy (DN) is the commonest cause of chronic kidney disease, and proteinuria isn't determent factor for the end stage renal disease in diabetics. Apelin is adipokine and have a beneficial role in early prediction of diabetic nephropathy. Few studies were done about apelin in diabetes. Purpose of the study: to investigate the association between the apelinergic system and diabetic nephropathy.
This study is randomized, controlled, parallel, prospective clinical study will be conducted on 60 patients diagnosed with type 2 diabetes mellitus at least five years ago. Patients will be recruited from Tanta University Hospital, Tanta, Egypt. Accepted patients will be randomized into 2 groups as the following: Control group: 30 patients will receive maximum tolerated dose of ACEI plus placebo pills for six months Treatment group: 30 patients will receive maximum tolerated dose of ACEI plus niclosamide tablets 1 gram once daily for six months The primary end point will be the change in Urinary albumin to creatinine ratio (UACR) and estimated glomerular filtration rate (eGFR) after six months of treatment
Worldwide, diabetic kidney disease (DKD) is the most common cause of chronic and end stage kidney disease. In parallel with the ever-increasing rates of obesity and type 2 diabetes (T2D), the incidence of DKD is expected to further increase in the coming years. DKD is a multi-factorial condition, involving pathophysiological factors such as chronic hyperglycemia, obesity, systemic- and glomerular hypertension, dyslipidemia, oxidative stress and pro-inflammatory cytokines. Large-sized prospective randomized clinical trials indicate that intensified glucose and blood pressure control, the latter especially by using agents that interfere with the renin-angiotensin-aldosterone system (RAS), halts the onset and (particularly) the progression of DKD, in both type 1 diabetes mellitus (T1DM) and T2DM patients. However, despite the wide use of angiotensin-converting enzyme (ACE) inhibitors and angiotensin receptor blockers (ARBs), a considerable amount of patients develop DKD, indicating an unmet need for renoprotective therapies. Sodium-glucose linked transporters (SGLT-2) inhibitors are a relatively novel glucose-lowering drug for the treatment of T2DM. These agents seem to exert pleiotropic actions 'beyond glucose control'. SGLT-2 inhibitors decrease proximal sodium reabsorption and decrease glomerular pressure and albuminuria in type 2 diabetes. In addition, SGLT-2 inhibitors reduce blood pressure and body weight. At this point in time, the renoprotective mechanisms involved with SGLT-2 inhibition still remain speculative, though a consistent finding is that SGLT-2 inhibitors reduce estimated eGFR after first dosing, which is reversible after treatment cessation. This "dip" indicates a renal hemodynamic phenomenon reminiscent of the RAS blockers and is thought to reflect a reduction in intraglomerular pressure. The potential renoprotective effects and mechanisms of combination therapy of SGLT-2 inhibitors and RAS inhibitors have not been sufficiently detailed in human type 2 diabetes. Therefore, the current study aims to explore the underlying mechanism of the improved renal hemodynamics and mechanistics of mono- and combination therapy with an SGLT-2 inhibitor and a RAS inhibitor on renal physiology in metformin and/or SU-treated T2DM patients.
