Filter by:The proposed research will determine the effectiveness of curcumin for improving the health and function of arteries in children and young adults with autosomal dominant polycystic kidney disease (ADPKD). The study also will provide insight into how curcumin improves artery health by determining the physiological mechanisms (biological reasons) involved and offer exploratory evidence if curcumin can slow kidney growth. This will be done by comparing these measurements in children and young adults who are randomized to receive either curcumin or placebo for 1 year.
Autosomal dominant polycystic kidney disease (ADPKD) is an inherited disease. We plan DNA analysis using the next generation sequencer (NGS) and examine the relationship between mutational types and clinical phenotypes. The accuracy of DNA analysis with NGS is tested by Sanger's method. The kidney and life survival curves will be compared between PKD1, PKD2 and non-ADPKD family members.
The purpose of the trial was to evaluate and describe the long term safety of tolvaptan in participants with autosomal dominant polycystic kidney disease (ADPKD).
The purpose of this study is to establish normal Magnetic Resonance quantitative values (tissues stiffness, Apparent Diffusion Coefficient values and Blood Oxygen Level Determination values for both renal cortex and medullary tissues and total renal blood flow) for young Autosomal Dominant Polycystic Kidney Disease patients with normal renal function, and normal young adult controls without Autosomal Dominant Polycystic Kidney Disease and normal renal function. Hypothesis: Newer Magnetic Resonance quantitative imaging parameters (tissue stiffness, Apparent Diffusion Coefficient, Blood Oxygen Level Determination levels, Magnetization Transfer and renal blood flow) will have different values in young adult ADPKD patients as compared to normal volunteers.
The purpose of this study is to learn if dietary habits can affect vasopressin secretion in patients with autosomal dominant polycystic kidney disease. Vasopressin increases the growth of kidney cysts and accelerates disease progression. Understanding how to control secretion of this hormone based on dietary habits may help to develop treatments to control this disease. The study will include about 60 patients from Tufts Medical Center. The study will last for 2 weeks. Blood and urine tests will be done 3 times during the study period. Subjects will be randomly assigned (by chance like flipping a coin), to one of two study groups. Group 1 will be given instructions to adjust their diet. This will include adjusting the amount of water, protein, and salt intake. Group 2 will have no adjustment of diet or water. The project has tremendous public health relevance, given the large numbers of people affected by autosomal dominant polycystic kidney disease and the substantial impact of the disease on morbidity, mortality, hospitalizations,dialysis or transplant, and societal costs of caring for those patients.
This study was designed to provide confirmation of safety of mesenchymal stem cells (MSCs) therapy in chronic renal failure due to autosomal dominant polycystic kidney disease (ADPKD).
The purpose of the study is to determine whether tolvaptan is effective and safe for the treatment of late-stage chronic kidney disease due to autosomal dominant polycystic kidney disease (ADPKD)
Gut microbes can influence numerous aspects of human biology. Alterations in the function and composition of gut microbial flora (gut microbiota ) have been linked to inflammatory bowel disease, chronic inflammation, dyslipidemia, diabetes mellitus, atopic disorders, cardiovascular disease, neoplasms, and obesity. However, little is known whether renal failure alters the composition of gut microbiota and whether an alteration in the gut microbiota of patients with renal failure impacts on the development of co-morbid conditions such as accelerated atherosclerosis, abnormal bone mineral metabolism, and chronic inflammation that are associated with renal failure. Nonetheless, several lines of evidence suggest that renal failure alters the chemical environment of the intestinal lumen, which could impose a selective pressure on the growth of certain gut microbes. The investigators hypothesize that the gut microbiota of patients with renal failure is different from those without renal failure. To test this hypothesis the investigators are conducting a cross-sectional study of gut microbiota in patients with different degrees of renal failure due to polycystic kidney disease (PKD).
The goal of this pilot study is to evaluate the feasibility of administering niacinamide to patients with autosomal dominant polycystic kidney disease, to develop methods to assess the biological efficacy of niacinamide, and to perform a preliminary exploration of its clinical effect on kidney cyst growth and kidney function.
The investigators multicenter randomized open-labelled study will investigate the efficacy of an everolimus based immunosuppression in reducing total native kidney volume in kidney recipients with autosomal dominant polycystic kidney disease compared to a calcineurin inhibitor-based immunosuppression.
