Activation of the Contact System and the Immune System in Patients With Chronic Kidney Disease....
Chronic Kidney Disease Requiring Chronic DialysisPatients with end-stage renal disease undergoing hemodialysis (HD) are burdened with extremely high mortality rates (15% per year) and during the early stage (≤120days) the mortality rate is even higher (27% per year). Cardiovascular complications and bloodstream infections (BSIs) account for the vast majority of deaths in HD patients. In Denmark, BSIs occur in 14% of HD patients per year and is most frequently caused by Staphylococcus aureus (44%). The most frequent infectious complication is endocarditis that has fatal outcomes in ≈50% of the cases. Overall, 10% of HD patients die within 30 days after a positive blood culture for S. aureus. This project aims to answer key questions regarding HD patients' decreased ability to fight S. aureus BSIs and in particular the potential exacerbating effect of HD. We hypothesize that HD patients' blood is significantly compromised by the process of HD, to an extend that lowers immunoactivity against S. aureus. Moreover, we hypothesize, that contact activation promotes the coagulability of blood thus promoting biofilm formation by S. aureus which increases the overall risk of BSI. We will test these hypotheses by collecting blood and analyzing the inflammation and coagulation status in plasma samples from participants before and after HD. We will compare the level of the inflammatory markers in plasma from participants undergoing HD (n=180) to the level in plasma samples from three control groups: healthy volunteers (n=120), participants with renal disease not in dialysis (n=60) and participants undergoing peritoneal dialysis (n=40).

Dapagliflozin and Renal Surrogate Outcomes in Advanced Chronic Kidney Disease
Chronic Kidney DiseasesThis is an investigator-led, randomized, open-label, blinded-endpoint, multicenter study that will include a total of approximately 225 subjects from 3 sites. Subjects with an estimated glomerular filtration rate (eGFR) of 10 to 30 mL/min/1.73m2 will be included. The goal of this study is to assess the efficacy and safety of dapagliflozin (Forxiga®, AstraZeneca) in reducing renal function progression and complications of chronic kidney disease (CKD) in patients with CKD stage 4 and 5 under the integrated CKD care. Subjects will be allocated to integrated CKD care program + dapagliflozin or integrated CKD care program alone. The primary end point is eGFR decline 12-52 weeks after randomization between 2 arms.

Chronic kidney disease (CKD) participants, specially does patients submitted to hemodialysis, is a population high exposed to plastics. The objective of our research is to be able to detect MNPLs on biological fluids of hemodialysis patients as well as their potential genotoxic and immunological damage.

MRI Technical Development and Applications in Kidney Disease
Chronic Kidney DiseasesKidney Transplantation2 moreMagnetic resonance imaging (MRI), as a non-invasive and non-contrast enhanced technique, has the potential to improve patient health care and management. The overall objective of proposed project is to: develop, customize, and optimize anatomic and functional MRI methods, explore the use of MRI methods to study CKD and evaluate post-transplant kidneys, and investigate the potential of MRI in the diagnosis, prognosis, and monitoring of the progression of renal dysfunction. In addition to direct studies of the kidney, brain MRI studies will also be performed to identify the cerebrovascular and cognitive effects of chronic renal function deficiency and medical treatment (e.g. hemodialysis and immunosuppression). The brain and kidneys have similar vascular bed, and both are susceptible to vascular injury, which provides the pathological basis for the widely recognized association of reduced renal function with prevalent cerebrovascular diseases (CVDs) and cognitive impairment (CI). The MRI methods in the brain will be applied to explore the origins for widely observed CVDs and prevalent cognitive impairment (CI) in kidney disease patients.

Antibiotic Prophylaxis and Renal Damage In Congenital Abnormalities of the Kidney and Urinary Tract...
Vesicoureteral RefluxRenal Hypodysplasia3 moreThe exact role of urinary tract infection in the appearance of chronic kidney disease is unclear. Children with congenital malformations of kidney and urinary tract have the higher risk of impairment of renal function. To understand if the use of antibiotic prophylaxis can reduce the risk of urinary tract infection in children with these malformations, this study will randomize children in two groups. Group A will not take antibiotic prophylaxis, Group B will take antibiotic prophylaxis for 2 years. This study will assess if antibiotic prophylaxis reduce the risk of urinary tract infections in these children and if urinary tract infections influence the appearance of renal damage. Our hypothesis is that prophylaxis reduce the risk of infection in severe vesicoureteral reflux and that urinary tract infections, in morphologically normal kidneys, will not result in chronic renal failure.

A Study Called SMART-Finder to Look for People With Increased Amounts of Albumin in the Urine (UACR...
Type 2 Diabetes MellitusChronic Kidney DiseaseThis is an observational study in which data from people with type 2 diabetes mellitus (T2DM) in Germany who use the medical app "myTherapy" are studied. In observational studies, only observations are made without specified advice or interventions. In people with T2DM, the body does not make enough of a hormone called insulin or does not use insulin well enough. The resulting high blood sugar level can cause damage to the kidneys over time. As a result, chronic kidney disease (CKD) can occur as a complication of T2DM. Kidneys filter extra water and waste out of the blood and make urine. CKD is a long-term, progressive decrease in the kidneys' ability to properly filter the blood. Abnormal amounts of proteins such as albumin in the urine are a sign of kidney damage, as proteins are normally kept in the blood. The amount of albumin in the urine is measured as so-called urine-albumin-creatinine-ratio (UACR) in this study. Studies in people with T2DM and CKD in a real-world care setting are limited, particularly those that look at the number of people concerned over time. The main purpose of this study is to learn how many people with T2DM have also increased amounts of albumin in the urine (UACR level) in users of the medical app "myTherapy" in Germany. In addition, researchers want to learn how these albumin levels change over time. To answer this, the researchers will collect the participant's UACR level at start of the study and about 12 months later. The UACR is measured by the participant's physician during routine care using urine dip-sticks. All participants of this study are already receiving or will receive one of the available T2DM treatments prescribed by their doctors according to the approved use or are regularly using devices to check their blood sugar levels. And they use the "myTherapy" app to support and track their T2DM therapy. The data collected includes both participant-reported data and physician-provided lab values. All data are entered into the "myTherapy" app by the participant. They will be collected from October 2022 to December 2024 and cover a period of up to 15 months per participant. Besides this data collection, no further tests or examinations are planned in this study.

Patients will be submitted to application of photobiomodulation therapy in the quadriceps muscle. Immediately after, the maximum isometric strength test of the quadriceps will be performed.

Dapagliflozin in Non Alcoholic Fatty Liver Disease Associated Cirrhosis and Its Role in Preventing...
NAFLD CirrhosisThe role of Dapagliflozin in the improvement in CKD in both diabetic and non-diabetic patients has been evaluated in the past. SGLT2i have also been found to be beneficial in NAFLD patients in improving the liver function parameters. It is also known that cirrhotic patients are at a higher risk of developing CKD at 1 year when compared to non cirrhotics. With this study we aim to study the role Dapagliflozin in cirrhotic patients in reducing the development of CKD, its impact on cirrhotic cardiomyopathy and its role in improvement of metabolic profile and liver related outcomes.
