Active clinical trials for "Renal Insufficiency"

Extreme preterm birth interferes with the development of the cardiovascular system. Both macro- as well as microvasculature undergoes extensive, organ specific maturation. Under normal fetal conditions, microvascular growth drives renal development and continues until 34-36 weeks of gestational age, while retinal vascular growth continues until term age. Studies show that there is association between low birth weight and cardiovascular dysfunction. According to the Barker hypothesis, this is due to nutritional shortage. In extreme preterm birth cases, this growth restriction is observed in neonatal life. In adult life, this suboptimal growth is associated with impaired renal and (micro)vascular function, hypertension, glucose intolerance and cardiovascular disease. According to the Brenner hypothesis, disrupted renal development results in hyperfiltration and hypertension, a process that subsequently promotes itself and leads to renal impairment. We will investigate macro- and microvasculature in different organs, including eye, kidney, heart and sublingual mucosa in former preterm infants, now aged 8-13 years old and age-matched controls. The expectation is that the results of this project will identify risk factors for cardiovascular-renal disease in the adult life of former preterm infants compared to the controls, while further analysis on mediators in neonatal life of this cardiovascular-renal outcome may provide new information on perinatal risk factors.

To examine two main predictor variables independently and then jointly in stratified and multivariate analyses for the outcomes of CSA-AKI, MARCE, need for RRT, and inpatient mortality, and the composite, as well as the outcomes of 30 day rehospitalization or death, and finally for the days out of hospital and alive adjusted to person-year of time Days from coronary angiogram performed with IOCM to cardiac surgery (1, 2, 3, etc) Thakar Acute Renal Failure (ARF) score (1 to 17) To examine the interrelationships between time in days between angiogram and surgery and the ARF Score with the Society of Thoracic Surgery (STS) Risk score for mortality

Patients with previous malignancies have increasingly been accepted for renal transplantation. However, post-transplant malignancy risk and survival rates of these patients are unknown. Our aim was to assess if previous malignancies pose an unnecessarily high risk of post-transplant malignant tumours and if the organs as a resource are too limited for investment in this patient group.

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 study was conducted to determine the rate of plasma volume (PV) re-expansion for each patient as a guide to rate of fluid removal (results published, refer to citations). A second study was conducted in order to assess the value of a BVA measurement in guiding prescription of clinical DW. A follow up BVA would then be done in order to check if patients were closer to ideal BV than prior to changing dry weight.

Prospective observational study of all consecutive cardio-vascular surgical patients treated with post-dilution hemofiltration with regional citrate anticoagulation as first-choice anticoagulation method. The filter life-span was assessed in the context of postoperative cardiac surgical antithrombotic prophylaxis. Reasons for termination of hemofiltration sessions were assessed. The second aim of this study was to assess the influence ACD-A based anticoagulation protocol on acid-base and ion homeostasis in cardiac surgical patients with acute renal failure.

Determination of Tissue Transit Time (TTT) as a parameter with high prognostic value to predict the functional course of the differential renal function and the development of the differential renal function after pyeloplasty

The purpose of this study is to investigate the differences of gut Microbiome/Metabolite between ESRD patients and healthy subjects. Two hundred and twenty three hemodialysis patients and 70 healthy subjects are recruited, and a cross-sectional study is performed.

Covid-19 is an important human and animal pathogen, it mostly causes respiratory and gastrointestinal symptoms. Clinical features range from a common cold to severe diseases such as severe acute respiratory distress syndrome, bronchitis, pneumonia, multi-organ failure, and even death. It seems to be less commonly affecting children and to cause fewer symptoms and less severe disease in this age group compared with adults. Clinicians have observed many extrapulmonary manifestations of COVID-19, as hematologic, cardiovascular, renal, gastrointestinal and hepatobiliary, endocrinologic, neurologic, ophthalmologic, and dermatologic systems can all be affected. This retrospective study that will be conducted at Hamad General Hospital in Qatar, aims to determine the renal involvement in all pediatric patients who were hospitalized with COVID-19 from March 1, 2020, to January 1, 2021.

Despite its known prevalence, a recent study conducted with Prof. Cacoub (unpublished) on the national health insurance database showed that iron deficiency was a poorly diagnosed and poorly treated comorbidity. In patients with Chronic Kidney Disease but Non-Dialysis, the determination of Ferritinemia and Transferrin Saturation Factoris performed in only 30% and 10% of cases whereas they should be performed routinely in inflammatory situations and in case of anemia (HAS 2011, KDIGO 2012). The objective of this study is to obtain updated data on the prevalence of iron deficiency in France in patients with CKD-ND, applying the international recommendations and those of the French Health High Authority (determination of ferritinemia and Transferrin Saturation Factor).

Post-operative acute renal failure is a severe post-operative complication and is associated with high mortality. The enhanced prediction score, including pre-as well as intra-operative predictors accurately predicted ARF following hepatic surgery. This prediction score allows early identification of patients at high risk of ARF and may support decision-making for protective kidney treatment.
