Active clinical trials for "Kidney Diseases"

To study the impact a difference in renal clearance of small and large molecules has on long-term survival.

This study involves a single family, including 1 patient, father, mother and sister. The patient presented with a new phenotype associating premature white hair, renal polycystosis, aortic dilation/dissection and lymphopenia. Samples were taken in order to identify the origin of the symptomatology highlighted in the index case. In addition, it was observed that mice invalidated for bcl-2, normal at birth and indistinguishable from control mice, showed, after one week, a phenotype similar to that observed in this patient. The overlap between the patient's main clinical signs (lymphopenia, white hair and polycystic renal disease) and the manifestations presented by the invalidated murine model for BCL2 suggests that its phenotype may be secondary to a Bcl-2 expression defect.

diabetic nephropathy is one of the leading causes of end stage renal disease

Pathological features of Autosomal Dominant Polycystic Kidney disease (ADPKD) include enlarged kidney volume, a higher frequency of digestive diverticulitis and abdominal wall hernias. Therefore, many nephrologists have concerns about the use of peritoneal dialysis (PD) in ADPKD patients. We aimed to analyze survival and technique failure in ADPKD patients treated with PD.

The aim of this study is to identify typical patterns of renal function evolution in patients with stage 4 chronic kidney disease, regularly followed in nephrology consultation and included in a French cohort.

Mental disorders have been shown to be associated with a number of general medical conditions (also referred to as somatic or physical conditions). The investigators aim to undertake a comprehensive study of comorbidity among those with treated mental disorders, by using high-quality Danish registers to provide age- and sex-specific pairwise estimates between the ten groups of mental disorders and nine groups of general medical conditions. The investigators will examine the association between all 90 possible pairs of prior mental disorders and later GMC categories using the Danish national registers. Depending on whether individuals are diagnosed with a specific mental disorder, the investigators will estimate the risk of receiving a later diagnosis within a specific GMC category, between the start of follow-up (January 1, 2000) or at the earliest age at which a person might develop the mental disorder, whichever comes later. Follow-up will be terminated at onset of the GMC, death, emigration from Denmark, or December 31, 2016, whichever came first. Additionally for dyslipidemia, follow-up will be ended if a diagnosis of ischemic heart disease was received. A "wash-out" period will be employed in the five years before follow-up started (1995-1999), to identify and exclude prevalent cases from the analysis. Individuals with the GMC of interest before the observation period will be considered prevalent cases and excluded from the analyses (i.e. prevalent cases were "washed-out"). When estimating the risk of a specific GMC, the investigators will consider all individuals to be exposed or unexposed to the each mental disorder depending on whether a diagnosis is received before the end of follow-up. Persons will be considered unexposed to a mental disorder until the date of the first diagnosis, and exposed thereafter.

Nonalcoholic fatty liver disease (NAFLD) is the most common cause of chronic liver disease in developed countries affecting approximately 30 % of the general adult population. It represents an important pathogenic factor in the development of type 2-diabetes and is associated with a high risk of cardiovascular disease. Previous studies of patients with chronic kidney disease (CKD) have demonstrated an increased risk for NAFLD and the presence of both CKD and NAFLD is likely to increase the risk for cardiovascular disease. The present protocol describes a study of the prevalence and etiology of NAFLD among patients with type 2-diabetes with CKD. The study is a cross-sectional study. Fat accumulation in the liver will be determined by Magnetic resonance (MR) spectroscopy and the prevalence of NAFLD among patients with type 2-diabetes with normal kidney function or CKD stage 3-5 will be investigated. A continuous glucose monitoring (CGM) for four days, Dual Energy X-ray Absorptiometry (DEXA) scanning, fibro scanning of the liver, bile acid analysis, metabolomic and lipidomic analysis will also be performed.

The luminal side of the entire vasculature is covered with a gel-like polymer called endothelial glycocalyx (EG). EG is important for the transport of molecules in and out of the blood cells and for endothelial function. EG protects the blood vessel wall, is likely to contribute to maintenance of normal blood pressure and the prevention of blood clot formation. Overall it is likely to avoid development of cardiovascular disease. A newly developed blood test, salt-blood test, can measure erythrocyte salt sensitivity and gives information about the condition of EG. EG can also be measured by release of endothelial glycocalyx proteins. Previous studies indicate that this EG is impaired by a number of chronic diseases, including chronic kidney disease. This study investigates the quality of glycocalyx in patients with chronic kidney disease, and compares with the layer in healthy.

Subjects will be measured with both a sensor and a reference device

Acute kidney injury is a complex clinical syndrome,associated with high short and long- term morbidity and mortality in critical ill patients.Acute kidney injury outcomes may vary from a complete resolution to a partial or incomplete recovery of renal function leading to increased mortality,prolonged hospitalization and risk of chronic comorbidities . The precise mechanism of acute kidney injury to chronic kidney disease transition is complex and not completely understood,especially in humans .Acute kidney injury outcomes depend upon the balance of adaptive and maladaptive repair.
