Filter by: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.
LIPS study (Lanreotide In Polycystic kidney disease Study) is a prospective randomized double blind placebo controlled study. The main objective is to prove that lanreotide, a somatostatin analog, is able to reduce the glomerular filtration rate decline over 3 years by at least 30%. Cardiovascular outcomes, blood pressure, quality of life and safety are among the secondary outcomes. The study, which will include 180 ADPKD patients, is scheduled to start in early 2014. An equal number of patients with chronic kidney disease stage 2 (90 patients with GFR 89 to 60 ml/mn/1.73 m2) and chronic kidney disease stage 3 (90 patients with GFR 59 to 30 ml/mn/1.73 m2) will be included. The primary endpoint (GFR decline) will be assessed by repeated measures, in the overall population as well as in the two GFR stratus.
Autosomal dominant polycystic kidney disease (ADPKD) is associated with the development of a variety of extrarenal manifestations of which polycystic liver disease is most common. The investigators aimed to assess the changes over time of liver volume in ADPKD patients and whether it is affected by the treatment with the somatostatin analogue, octreotide. 35 ADPKD patients (14 males) aged 34±8 years were randomly assigned to 36 month treatment with placebo (n=18) or octreotide (n=17). Clinical and liver parameters at magnetic resonance (RM) were evaluated at baseline, study end and after 24 months of drug withdrawal.
Autosomal dominant polycystic kidney disease (ADPKD) is associated with early onset hypertension and left ventricular (LV) hypertrophy. Since LV hypertrophy is associated with LV diastolic function impairment, we aimed to assess the changes over time of LV diastolic function in ADPKD patients and whether they were affected by the treatment with the somatostatin analogue, octreotide. 35 ADPKD patients (14 males) aged 34±8 years (mean glomerular filtration rate 82±26 mL/min/1.73m2) were randomly assigned to 36 month treatment with placebo (n=18) or octreotide (n=17). Clinical and echocardiography parameters were evaluated at baseline and study end. LV mass (M) and ejection fraction (EF) were calculated according to Devereux formula and biplane Simpson's algorithm, respectively. LV filling was assessed by mitral and pulmonary vein flow velocity curves and mitral annulus early diastolic velocity peak (Ea) by tissue Doppler imaging.
Triptolide was shown in experimental studies to inhibit the cyst formation and growth in ADPKD models, while triptolide-containing formulation was revealed to potentially slow the disease progression in several proteinuric ADPKD patients in our clinical practice. It remains to be shown the effect of triptolide-containing formulation on total kidney volume (TKV) enlargement and renal function protection in ADPKD patients.
The aim of this study is to identify families with ADPKD , characterize the phenotype and screen for mutations in known genes (PKD1 and PKD2, and then HNF1b and UMOD in PKD1 PKD2 negative carriers). Genome wide analysis will be performed in families without mutations identified.
The purpose of this study is to find out if radiology tests of the kidneys as opposed to glomerular filtration (GFR) tests (GFR test - a lab test that measures kidney function) follow progression of polycystic kidney disease (PKD) the best. PKD patients at risk for progression to renal failure (dialysis or transplantation) have been identified and include those who have been diagnosed with high blood pressure early, the presence of the PKD1 gene (the inherited abnormality responsible for the majority of PKD), men as opposed to women, those with episodes of visible blood or increased protein in their urine, and women who have experience more than three pregnancies. Individuals who are diagnosed with PKD in the first year of life or in utero (before birth) are also at high risk for progression to renal failure. This study will also facilitate understanding of human diseases at the cellular and molecular level. We will be identifying genetic factors that may influence the severity of polycystic kidney disease (PKD). You are being asked to provide a sample of blood for the purpose of DNA or other biochemical analyses.
In patients with polycystic kidney disease, pain may be resistant to drug therapy and may reduce quality of life. This study investigate the effect of renal denervation on this pain.
Sirolimus (SIR) has lead to a reduction of overall kidney size, a decrease in cyst density and general tubular cell proliferation in animal models, and to a reduction of the increase in creatinine and blood urea nitrogen by 34 and 39 percent respectively, as well as a reduction of cyst proliferation, expressed by a 30 percent reduction of overall kidney enlargement, a reduction in general cyst volume, and a reduction of the cyst volume density in the renal cortex in humans. However, despite promising data from animal- and in vivo studies, most mammalian target of rapamycin inhibitor (mTOR-I) studies in patients with autosomal-dominant polycystic kidney disease (ADPKD) produced only subtle if any clinically relevant effects on cyst growth and the preservation of renal function. In this study we will investigate if pulsed administration of SIR in a fixed weekly oral dose of 3 mg over 24 months compared to placebo significantly reduces cyst growth and preserves excretory renal function in patients with ADPKD and an estimated glomerular filtration (eGFR) rate below 60 mL/min per 1.73m2.
