Alterations in the Plasma Proteome of Early-Onset Severe Preeclampsia

The hypothesis of this study is that many plasma proteins are altered in concentration and structure in preeclampsia and the elucidation of these alterations will add to the poorly understood pathophysiology of preeclampsia. In this study we will compare the maternal plasma proteomes of early-onset severe preeclampsia versus healthy controls, compare protein expression and quantification of the maternal plasma proteome at the time of diagnosis of EOS-preeclampsia to the plasma...


Biomarkers of Cardiovascular Complications in Chronic Kidney Disease

Identification of new retention solutes associated with cardiovascular (CV) toxicity in Chronic Kidney Disease (CKD) patients will help to better understand the pathophysiological mechanisms at stake and to prevent CKD-associated mortality and morbidity. For a molecule to be defined as a toxic retention solute, plasma accumulation in the course of CKD has to be demonstrated but also proof needs to be made that plasma accumulation during CKD is indeed associated with an increase...

Comparative Study of Menstrual Blood and Systemic Blood

Analysis of Plasma for Diagnosis and Follow-up of Neurofibromatosis Type 1

The purpose of this study is to find blood plasma based biomarkers of disease progression in neurofibromatosis type 1 (NF1). NF1 is associated with the development of benign cutaneous tumors as well as a variety of malignancies. Analysis of plasma DNA and chemical composition may provide tools for diagnosis and follow-up of NF1. The hypothesis of the study is that NF1-associated tumor burden and malignant transformation of tumors can be detected in plasma. To test this hypothes...

Plasma Glycosaminoglycans as Diagnostic and Prognostic Biomarkers in Surgically Treated Renal Cell Carcinoma

In this study, we profiled plasma glycosaminoglycans (GAGs) in a retrospective consecutive series of patients with a radiographic finding of renal mass referred to primary surgery for renal cell carcinoma (RCC). A control group was formed by measuring plasma GAGs in healthy volunteers. The primary endpoints were the specificity and sensitivity of plasma GAGs in the detection of early stage RCC in pre-surgical samples versus healthy individuals. We further analyzed how plasma GA...

Assessment of Circulating Copeptin Levels in Healthy Subjects and Patients With Renal Insufficiency After Oral Water Load and Hypertonic Saline Infusion

The are 2 principal goals in this study: 1. To measure plasma copeptin levels in healthy subjects and to correlate them with plasma AVP concentrations and urine osmolalities in iso-, hypo-, and hyperosmolar states. 2. To measure plasma copeptin concentrations in patients with chronic renal failure under the same conditions described above, in order to characterize the impact of renal function on circulating copeptin levels in correlation to plasma AVP and u...

Effect of Tolvaptan on Renal Plasma Flow (RPF) and Glomerular Filtration Rate (GFR) in ADPKD

Polycystic kidney disease (ADPKD) is a common genetic disorder, characterized by the formation of cysts in the kidneys, causing gradual renal function-loss. Previous studies have shown that, reduced glomerular filtration rate (GFR) and renal plasma flow (RPF) play a role in the progression of renal disease in ADPKD. Tolvaptan is a vasopressin 2 antagonist, which seems to reduce the growth of total kidney volume (TKV) and the decline in e-GFR in ADPKD. The mechanism is not fully...

Plasma Concentrations of Calcium, Phosphate, FGF23, Klotho, 25 (OH) D3 and 1,25 (OH) 2D3 From Patients Who Wants to Have Children

1,25-dihydroxy-vitamin D3 (1,25 (OH) 2D3) or calcitriol regulates plasma calcium and phosphate concentrations in the blood by stimulating intestinal absorption and renal reabsorption of calcium and phosphate. 1.25 (OH) 2D3 is formed by the renal 1α25OH vitamin D-hydroxylase (Cyp27b1) and inactivated by the renal 25-hydroxy vitamin D-24-hydroxylase (Cyp24). Unpublished studies in mice revealed an inhibitory effect of 1.25 (OH) 2D3 on embryo implanation. An excess of 1.25 (OH) 2...

Prevention of Acute Kidney Injury - Molecular Mechanisms of Dietary Pre-conditioning in Human

The protective effect of the low-calorie diet in donor on transplant qualities and functions in receptor will also be investigated. Analysis of transcriptome, lipidome, metabolome, epigenome, proteome und phosphoproteome through tissue samples as well as blood samples for comparison of low-calorie diet and no-diet groups.

Collection of Human Metabolic Tissues

This project aims at identifying new determinants of type 2 diabetes in severe obesity. To do so, a biological collection, including tissues of interest in the field of metabolism, will be collected during bariatric surgery in obese patients. Three different groups of metabolic status of patients, corresponding to different stages of evolution of the disease, will be constituted: type 2 diabetes, insulin resistance, insulin sensitivity. The main objective is to compare, betwee...

The Effects of Trout Fed With a Vegetable Based Feed on Cardiovascular Risk Markers and Plasma Proteome

Fish from the aquaculture sector constitutes an increasing part of the fish consumption in Denmark. The most important farmed fish in Denmark is the rainbow trout. Due to limited access of wild fish for the feed production, alternative feeding regimes of vegetable origin such as vegetable proteins and rapeseed oil are used instead of marine feed. This change in feeding regime may affect flesh quality and health and nutritional properties as the content of long-chain n-3 polyuns...

Nephron Sparing Renal Surgery and Total Nephrectomy

The incidence of the diagnosis of renal cell carcinoma has increased during the past two decades because of the detection of small renal tumours that occur incidentally because of increased use of CT-scanning (1,2). Postoperative renal insufficiency was a significant independent predictor of overall and cardiovascular specific survival (3). "Nephron-sparing" surgical techniques are now preferred for small tumor masses and laparoscopic intervention is replacing open surgery at c...

The purposes are 1. to measure the effect of dialysis with glucose in dialysis water on blood pressure, pulse rate, plasma concentration of glucose, plasma concentrations og insulin, glucagon, growth hormone, renin, angiotensin II, endothelin and body temperature, and 2. to analyse the relationship between the changes in blood pressure and changes in vasoactive hormones

Plasma Oxalate in Patient With Short Bowel

Hyperoxaluria due to fat malabsorption is seen in patients suffering from short bowel and can lead to stones and nephrocalcinosis. Not all patients are prone to these renal complications. only urinary oxaluria is measured in practice. Plasma oxalate shouldn't increase theoretically in these patients. However recent report showed an increase of plasma oxalate in patient with enteric hyperoxaluria. The aim of this study is to assess the plasma oxalate distribution in this specifi...

Blood Volume Analysis and Renal Outcomes in Hemodialysis

The objective of the proposed study is to demonstrate that serial blood volume analysis (BVA) using RI-BVA (BVA-100, Daxor, NY) can be used to guide changes in prescription of dry weight for hemodialysis patients. The knowledge of a patient's ideal BV and degree of hypervolemia using these measurements can be used to change the prescription of DW in an objective way instead of the current standard of practice, which is based on subjective prescription of dry weight. A first stu...
