Filter by:The human gut microbiome has been associated with many health factors but variability between studies limits the exploration of effects between them. This study aims to systematically characterize the gut microbiota of various critical chronic diseases, compare the similarities and differences of the microbiome signatures linked to different regions and diseases, and further investigate their impacts on microbiota-based diagnostic models.
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.
Leveraging a unique combination of synchronized web and mobile applications, this 3 year SBIR Phase II project will fully develop and pilot test My Kidney Guru-a program that will offer pediatric patients with CKD developmentally appropriate, interactive, and engaging instruction and practice opportunities to build knowledge and skills to manage CKD.
Hyperuricemia is a common condition in patients with chronic kidney disease (CKD) in the glomerular filtration rate. Recently, it has been suggested that uric acid is related to a mineral and bone disease of CKD (CKD-MBD) since the high concentration of uric acid is associated with the harmful effect of vitamin D. The proof of concept of the association between acid uric acid and CKD-MBD is based on a prospective study (sample size 6) that observed, after 1 week of use of allopurinol, an increase in the concentration of 1,25(2D, a result independent of the concentration of calcium, phosphorus, 25(OH)D and PTH. An experimental study found that hyperuricemia could modify the expression of the 1α-hydroxylase enzyme, consequently reducing 1,25(OH). The current study aims to evaluate the action of allopurinol on CKD-MBD biomarkers (25(OH)-vitamin D, 1,25(OH)2D, FGF-23, PTH, calcium and phosphorus). We hypothesize that allopurinol can improve serum levels of 1,25(OH) 2D and PTH. This is a controlled, randomized, double-blind study, defined as a filtration rate < 60ml/1.73 m², according to the CKD-EPI equation. Inclusion criteria: patients with stages III, IV and V CKD who are not on dialysis with a serum level of 25(OH)-vitamin D >20 ng/ml. Exclusion criteria: Patients diagnosed with gout, undergoing treatment with allopurinol, patients already in use and drugs with sensitivity to the drug. Based on a previous study, we calculated a sample for 2 groups (placebo and drug) with pre and post-measurements (a total of 4). Considering a standard deviation of 4 and a difference of 7 in the treated group, 3 in the placebo group, and an alpha error of 5%, we calculated a sample of 25 patients in each arm.
The aim of the study is to evaluate the impact of gum acacia on serum levels of protein-bound uremic toxins (indoxyl sulfate and p-cresyl sulfate).In addition to the evaluation of its effect on metabolic profile and disease progression in chronic kidney disease patients.
In Tunisia, diabetes is a serious public health problem, its prevalence reaches 22.9% of people aged 18 and over and is likely to affect a quarter of the population by 2045. Diabetic kidney disease is the most common and severe complication of diabetes. It is both a major cause of end-stage renal disease and a risk factor for mortality and cardiovascular morbidity, thus becoming an additional public health concern. Early diagnosis of diabetic kidney disease makes it possible to manage patients more effectively and in a multidisciplinary way, to delay its progression to chronic renal failure.
The aim of the study is to evaluate the efficacy and safety of cholestyramine in the management of hyperphosphatemia in hemodialysis patients. Colestilan is a non-metallic phosphate binder that acts as an anion-exchange resin. Colestilan itself is not absorbed after oral administration, and it is able to bind dietary phosphate within the gastrointestinal tract and thus prevent absorption of the mineral. Initial, Phase II, studies showed that it reduces serum phosphorus levels in dialysis patients with hyperphosphatemia without affecting serum calcium levels. There are no studies conducted about the feasibility and efficacy of cholestyramine as an oral phosphate binder in hemodialysis patients. Relying on the efficacy and safety of bile acid sequestrants such as colestilan and colestipol in the management of hyperphosphatemia and hypercholesterolemia in hemodialysis patients, cholestyramine is selected to be studied in hemodialysis patients. A total of 80 patients will be recruited and divided into 2 groups: - Group 1: (cholestyramine 12 gram), 40 patients will take a dose of cholestyramine 4-gram sachet in 150-200 ml water or juice three times daily within meals as an add on therapy with standard therapy calcium-based phosphate binder (Calcimate). Group 2: Control group, 40 patients will take only the standard therapy calcium-based phosphate binder (Calcimate). Time of the trial will be two months (8 weeks trial period) Baseline characteristics: The following data will be collected from all patients at baseline 1. Age, sex, weight, duration of ESRD and hemodialysis comorbidities. 2. Dialysis duration, serum phosphate level, serum calcium level, iPTH, BUN, Cr (mg/d L), Albumin (mg/d L), Hb (g m%), renal function test, liver function test, blood glucose level, TG, total cholesterol level, LDL-C, HDL.C. After the end of trial, we will examine if cholestyramine has a significant efficacy on reducing serum phosphate level in adult hemodialysis patients.
The purpose of this study is to test whether or not regular exercise training may improve brain blood flow regulation in patients with chronic kidney disease (CKD).
This is a longitudinal observation of kidney function, immune system and gut microbiota before and 24 weeks after a live kidney transplantation conducted in donor and recipient pairs living in the same household. Outcome measures include kidney function, body composition, blood pressure, gut microbiome composition, metabolomics and immune cell states.
The aim of this study is to test the hypothesis that the effects on albuminuria of combination treatment with the endothelin receptor antagonist zibotentan and SGLT2i dapagliflozin are complimentary and additive while the fluid retaining effects of zibotentan can be mitigated by dapagliflozin.
