A Research Study to Find Out How Semaglutide Works in the Kidneys Compared to Placebo, in People...
Diabetes MellitusType 21 moreWe are doing this study to learn more about how semaglutide may help fight chronic kidney disease in people with type 2 diabetes. We are doing this by looking into how semaglutide works in the kidneys. Participants will either get semaglutide or placebo (a 'dummy' medicine) - which treatment participants get is decided by chance. Semaglutide is a medicine doctors can prescribe in some countries for the treatment of type 2 diabetes. Participants will get the study medicine in a pen. Participants will use the pen to inject the medicine into the skin once a week. The study will last for about 1 year. Participants will have 11 visits to the clinic, and 2 phone visits. Some of the visits could be in different locations. Study staff will take blood samples at most of these visits. At 9 visits, participants will be asked to bring a sample of their first morning urine. At 4 of the visits participants will have to bring urine that they have collected over the last 24 hours. The study includes magnetic resonance imaging (MRI) scans of participants' kidneys which is a test that shows a detailed picture of organs and other parts inside the body. The scan will last for 30 minutes, and is free of radiation.
Safety and Efficacy of Two Year of RAAS Alone or in Combination With Spironolactone Therapy
Renal InsufficiencyChronic1 moreNephroNet proposes to examine whether combining Spironolactone with maximal RAAS blockade will further reduce urinary protein at one year and whether prolonged therapy (24 months) is able to slow the decline in GFR. Because of combination MRA and RAAS therapy significantly increases the risk for clinically significant hyperkalemia, we also plan to determine whether the addition of Patiromer to these patients facilitates the use of combination therapy and allows a larger proportion of diabetic patients the potential benefit of combination therapy on renal function.

Bone Marrow and Kidney Transplant for Patients With Chronic Kidney Disease and Blood Disorders
Chronic Kidney DiseaseAcute Myeloid Leukemia (AML)15 moreThe main purpose of this study is to examine the outcome of a combined bone marrow and kidney transplant from a partially matched related (haploidentical or "haplo") donor. This is a pilot study, you are being asked to participate because you have a blood disorder and kidney disease. The aim of the combined transplant is to treat both your underlying blood disorder and kidney disease. We expect to have about 10 people participate in this study. Additionally, because the same person who is donating the kidney will also be donating the bone marrow, there may be a smaller chance of kidney rejection and less need for long-term use of anti-rejection drugs. Traditionally, very strong cancer treatment drugs (chemotherapy) and radiation are used to prepare a subject's body for bone marrow transplant. This is associated with a high risk for serious complications, even in subjects without kidney disease. This therapy can be toxic to the liver, lungs, mucous membranes, and intestines. Additionally, it is believed that standard therapy may be associated with a higher risk of a complication called graft versus host disease (GVHD) where the new donor cells attack the recipient's normal body. Recently, less intense chemotherapy and radiation regimens have been employed (these are called reduced intensity regimens) which cause less injury and GVHD to patients, and thus, have allowed older and less healthy patients to undergo bone marrow transplant. In this study, a reduced intensity regimen of chemotherapy and radiation will be used with the intent of producing fewer toxicities than standard therapy. Typical therapy following a standard kidney transplant includes multiple lifelong medications that aim to prevent the recipient's body from attacking or rejecting the donated kidney. These are called immunosuppressant drugs and they work by "quieting" the recipient's immune system to allow the donated kidney to function properly. One goal in our study is to decrease the duration you will need to be on immunosuppressant drugs following your kidney transplant as the bone marrow transplant will provide you with the donor's immune system which should not attack the donor kidney.

Sodium Bicarbonate and Mitochondrial Energetics in Persons With CKD
Chronic Kidney DiseasesMetabolic Acidosis5 moreSkeletal muscle metabolic health is critical for mobility and an underrecognized target of metabolic acidosis in chronic kidney disease. Impaired muscle mitochondrial metabolism underlies poor physical endurance increasing the risk of mobility disability. The proposed project will use precise in vivo tools to study the pathophysiology of poor physical endurance in a clinical trial treating metabolic acidosis among persons living with chronic kidney disease.
Telemonitoring of Hypertensive Patients With Chronic Kidney Disease
Chronic Kidney DiseasesBackground: Hypertension, together with poorly controlled blood pressure (BP) are known risk factors for kidney disease and progression to kidney failure as well as increased cardiovascular (CV) morbidity and mortality. Several studies in patients without kidney disease have demonstrated the efficacy of home BP telemonitoring (HBPT) for BP control. Objective: The primary aim of this study is to assess the mean difference in systolic BP (SBP) at 12 months, from baseline in remote dwelling patients with hypertension and chronic kidney disease (CKD) in Northern Alberta, Canada, comparing HBPT + usual care versus HBPT + a case manager. Other secondary objectives, including cost-effectiveness and acceptability of HBPT as well as occurrence of adverse events will also be assessed. Methods Design: This study is designed as a pragmatic randomized controlled trial (RCT) of HBPT plus clinical case management compared to HBPT with usual care. Setting: Peace River region in Northern Alberta Region, Canada. Patients: Primary care patients with CKD and hypertension. Measurements: Eligible patients will be randomized 1:1 to HBPT + BP case management versus HBPT + usual care. In the intervention arm, BP will be measured 4 times daily for 1 week, with medications titrated up or down by the study case manager until guideline targets (systolic BP [SBP]: <130mmHg) are achieved. Once BP is controlled, (i.e., to guideline-concordant targets), this 1-week protocol will be repeated every 3 months for 1 year. Patients in the control arm will also follow the same BP measurement protocol, however, there will be no interactions with the case manager; they will share their BP readings with their primary care physicians or nurse practitioners at scheduled visits. Limitations: Potential limitations of this study include the relatively short duration of follow-up, possible technological pitfalls, and need for patients to own a smartphone and have access to the internet to participate. Conclusions: As this study will focus on a high-risk population that has been characterized by a large care gap, it will generate important evidence that would allow targeted and effective population-level strategies to be implemented to improve health outcomes for high-risk hypertensive CKD patients in Canada's remote communities.
Impact of Dapagliflozin on Intestinal Microbiota Composition and on the Metabolites Derived From...
Chronic Kidney DiseasesChronic kidney disease (CKD) is a common disease affecting 10-12% of the adult population and characterize with high-risk cardiovascular morbidity and mortality with progression of CKD. Treatment with sodium-glucose cotransporter 2 inhibitors (iSGLT2) not only improves hyperglycemia and type 2 diabetes (T2D) but also results in body-weight loss, a reduction in blood pressure, and a decrease of cardiovascular events and progression of renal failure in both diabetes and non-diabetes patients.(Heerspink et al. 2020) Therefore, dapagliflozin is now associated with the inhibitors of the renin-angiotensin system to reduce kidney events. However, the mechanisms underlying the effects of dapagliflozin on the renal function remain unclear. When renal failure occurs, it impairs the removal of several metabolites called uremic retention solutes. If these retention solutes exhibit deleterious interferences with biochemical/physiological functions, they are referred to as uremic toxins as they can contribute to the manifestations of the uremic syndrome and are associated with a high cardiovascular morbidity and mortality and with progression of CKD. Many of the uremic toxins are not produced by the body itself but rather derived from gut microbiota metabolism such as the well-known trimethylamine-N-oxide (TMAO),p-cresyl sulfate (PCS), phenyl sulfate (PS), indoxyl sulfate (IS), and indole-3-acetic acid (IAA).The gut microbiota composition in a uremic context has been the subject of an increasing number of publications and majority of them confirm a decrease of gut microbiota richness and deep modifications.Recently, an animal study suggested that dapagliflozin, subtly improve the composition of the gut microbiota in mice with T2D and another preliminary clinical study didn't observe a modification in the fecal microbiome after dapagliflozin initiation.But in other study, empagliflozin significantly reshaped the gut microbiota after 1 month of treatment in T2D patients and be associated with shifts in plasma metabolites. Similarly, canagliflozin reduces plasma uremic toxins in a CKD mice model.However, it remains unknown whether treatment with dapagliflozin alters the gut microbiota in CKD patients without T2D; furthermore, the relationship between the gut microbiota, uremic toxins production and CKD-related beneficial effects of dapagliflozin remains elusive. Herein, the investigator will investigate the clinical benefits of dapagliflozin and possible associations between its renal function benefits and alterations in plasmatic gut microbiota-derived metabolites and the gut microbiota composition in non-T2D CKD patients. To this end, the investigator will conduct an observational clinical trial in non-T2D CKD patients with the primary aim of investigating dapagliflozin-induced compositional changes of intestinal gut microbiota.
