Filter by:RDN-ADPKD is a prospective, randomized (1:1, central randomization), single-center, hypothesis-generating, feasibility study. The purpose of the RDN-ADPKD study is to demonstrate efficacy and document safety of renal denervation (RDN) with the Paradise System in hypertensive patients with ADPKD.
People with autosomal dominant polycystic kidney disease (ADPKD) develop high blood pressure and kidney disease. Previous studies have shown that a commonly occurring chemical, nitric oxide (NO), is reduced in ADPKD, and may contribute, in part, to high blood pressure in this condition. Nitrate is found in high concentrations naturally in beetroots, and increases NO. The aim of this study is to determine if beetroot juice reduces blood pressure in hypertensive people with ADPKD.
Autosomal dominant polycystic kidney disease (ADPKD) is characterized by progressive formation of renal cysts which ultimately lead to a loss of renal function. Tolvaptan (a V2R antagonist) is currently the only effective treatment for preserving renal function in ADPKD. However, side-effects such as polyuria limit its tolerability and thereby the therapeutic potential. This study will test whether co-administration with hydochlorothiazide can improve V2RA efficacy (slowing kidney function decline) and tolerability (quality of life) in ADPKD. Approximately 300 patients will be enrolled.
The primary objective of this study is to evaluate the use of Super-resolution ultrasound (SRU) to assess the intrarenal microvasculature in patients with Autosomal Dominant Polycystic Kidney Disease (ADPKD) and healthy volunteers.
The aim of the study is to assess the improvement of health in patients affected by CKD when they are exposed to non-pharmacological treatment strategies as nutritional program (NP), physical activity program (PA) and mindfulness program (MP), when they are conveyed to the patient by means of digital technologies or not. In the present study, non-pharmacological interventions conveyed by a digital technology (investigational arm) will be compared to a standard, paper-based approach (control arm).
Autosomal dominant polycystic kidney disease (ADPKD) is the most common inherited kidney disease characterized by cystic kidneys and caused by mutations in the polycystic kidney disease and other rare genes. It is associated with salt-sensitive hypertension, which accounts for the majority of morbidity and mortality. About 70% of patients with ADPKD develop hypertension, prior to the onset of kidney function decline. Early onset hypertension, despite its treatment, is independently associated with rapid kidney function decline. The investigators hypothesize that a high-sodium diet in patients with ADPKD is required for the development of vascular stiffness, which precedes hypertension, and that treatment with amiloride reverses this phenomenon.
Primary sarcopenia is used to describe aging and progressed with the physiologic decline. Secondary sarcopenia is associated many chronic disease, including acquired immune deficiency syndrome, cancer, chronic heart failure, chronic lung disease, liver cirrhosis, chronic kidney disease and rheumatoid arthritis. In the past, nutrition status is evaluated by body mass index, mid-upper -arm circumference and serum albumin. Bioelectrical impedance analysis is also a common method to measured body composition, but bioelectrical impedance analysis will be affected by tissue edema and ascites. In contrast, cross-section imaging, such as computed tomography and magnetic resonance can analyzed abdominal muscle and fat accurately. Since computed tomography and magnetic resonance imaging can evaluate the severity of polycystic liver and kidney disease. Investigators can use cross section imaging at 3rd lumber level to separate skeletal muscle and fat tissue. Previous studies showed the quantity and quality of abdominal muscle are important prognostic factor after liver transplantation. Besides, chronic kidney disease and receiving renal placement therapy lead protein catabolism and make patients with end stage renal disease have sarcopenia. Finally, patients with polycystic liver and kidney disease have organomegaly, which causes abdominal distention and poor appetite. Therefore, the aim of this study is to observe the association between skeletal muscle mass and the severity of disease and to study whether change in hepatic and renal volumes is associated with change in muscle mass.
This is a Phase 3, open-label, roll-over study to demonstrate the continued hepatic and non-hepatic safety and renal efficacy of lixivaptan in participants with ADPKD who previously experienced abnormal liver chemistry test results while treated with tolvaptan, were permanently discontinued from the drug for that reason, and subsequently completed study PA-ADPKD-303, the open-label lead-in study with lixivaptan.
The purpose of this study is to assess homocysteine metabolism and systemic endothelial function at the early stages of the disease and determine the prognostic value of homocysteine, related metabolites, and markers of endothelial function and injury to estimate renal disease severity and progression in patients with early Autosomal Dominant Polycystic Kidney Disease (ADPKD).
The purpose of this research is to study the effectiveness and safety of the medication PB in slowing the frequent urination related to tolvaptan as long-term treatment of Autosomal Dominant Polycystic Kidney Disease (ADPKD), or frequent urination related to inherited nephrogenic diabetes insipidus as an inherited condition or as an acquired condition from prior treatment with lithium.
