Active clinical trials for "Mesenteric Ischemia"

Digestive tract is supposed to be the motor of multiple organ failure. In ICU patients, mesenteric ischemia appears even when macrocirculatory parameters are controlled especially in our experience in patients coming in ICU after a cardiac surgery. The investigators suppose that microcirculatory failure develops and results in suffering of non major organs like muscle, skin and digestive tracts. In this study the investigators monitor digestive tract with plasmatic IFABP dosage and microcirculatory circulation with NIRS during a VOT and plasma glycocalyx measurements. The population is composed by patients having coronary artery bypass during cardiopulmonary bypass. The first aim of this study is to show that digestive tract is suffering with the use of extracorporeal circulation and will be assessed with Plasmatic Intestinal Fatty Acid Binding Protein when IFABP will more than 300 pg/ml ; and with citrullinemia when citrullinemia will be less than 20 micromol/L. The second aim is to investigate link between endothelial dysfunction and digestive tract. Endothelial dysfunction is assessed with tissular oxygen saturation before, during and after a vascular occlusion test of 3 minutes (measurement of basal value, desaturation curve, resaturation curve and hyperemic response by measurement of area under curve). Endothelial glycocalyx and NO pathway will be investigate (see under) Our objective is to enroll 100 patients. The same study will be done in a group of patients who benefit from coronary artery bypass without extracorporeal circulation to see the effects of extracorporeal circulation support.

To investigate a number of blood based parameters in patients with intestinal ischaemia compared to patients with other acute abdominal diseases.

The aim of the SURVIBIO study is to characterize accurate biomarkers for acute mesenteric ischemia, in particular at early stages. In the study, the development of biomarkers will be based on the analysis of human biological samples from patients and controls that will be conserved in a biological library. Samples will be analysed in the Laboratory for Vascular Translational Sciences (LVTS, Inserm U1148), in the Department of Biochemistry (Pr Puy, Dr Peoc'h), in Paris V university , in Imperial College of London (Pr Dumas), in Jacques Monod Institute and in Maastricht University Medical Center . The candidate markers will be determined according to an a priori method (form markers already described in the literature) and with no a priori strategy using -omics methods.

Minimal invasive intra-arterial prostaglandin therapy is currently being offered as an established and safe treatment approach for Non-occlusive mesenteric ischemia (NOMI). So far, there are no data that prospective evaluate clinical response parameters of this method and corresponding criteria for response. The investigators are therefore planning a prospective observational study on NOMI patients with the aim to collect routine clinical data, data from advanced angigraphic imaging and data from blood biomarkers of intestinal ischemia before/at implementation of intra-arterial vasodilatory therapy. From these three data packages, the investigators hope to subsequentially derive criteria to better predict response to therapy.

To investigate which findings on a non-specific CT scan that predict acute primary intestinal ischaemia.

Chronic meseteric ischemia (CMI) is a disease characterized by an insufficient blood supply to the intestines due to a narrowing (stenosis) of one or multiple intestinal arteries. The primary symptom is abdominal pain especially during meal digestion. Currently the diagnosis of CMI is heavily reliant on the exclusion of differential diagnoses. With this study we wish to evaluate whether a newer CT technology called dual-energy CT (DECT) may be able to visualize this altered blood flow during meal consumption.

Retrospective population-based study on epidemiology of acute mesenteric ischemia in Estonia Study objective is to describe epidemiologic features in adult patients with acute mesenteric ischemia during years 2016-2020. Patients from all hospitals in Estonia are included.

To assess the evolution of biological markers of mesenteric ischemia during ultratrail.

Background: Acute kidney injury (AKI) is a common and serious postoperative complication in children with congenital heart disease. In this prospective cohort study, we tested the hypothesis that renal desaturation defined as a 20% decline of renal tissue oxygen saturation (SrtO2) from the baseline value is associated with AKI in infants undergoing ventricular septal defect (VSD) repair with cardiopulmonary bypass (CPB). Methods: Infants aged 1 months to 12 months and scheduled to undergo VSD repair with CPB were eligible. SrtO2 was monitored using a tissue near-infrared spectroscopy. Renal desaturation was defined as a decrease of SrtO2 measurement from the baseline value for more than 20% lasting for more than 60 s. The primary outcome was the incidence of AKI on postoperative 1-3 days according to the Kidney Disease: Improving Global Outcomes criteria. The secondary outcomes included different stages of AKI, duration of postoperative mechanical ventilation, duration of intensive care unit (ICU) and hospital stay, renal replacement therapy (RRT), and in-hospital mortality.

This is a prospective, multicentre observational study screening all adult patients admitted to a participating hospital over a 6-month study period (may be adjusted to 4-8 months according to recruitment) and including all patients with suspicion of or confirmed acute mesenteric ischaemia (AMI). Only admission data and hospital mortality outcome will be collected for patients in whom suspicion of AMI is not confirmed. For patients with confirmed AMI full data collection regarding diagnostics, management and long-term outcome is required. Investigators aim to recruit 40-50 sites with expected median of 10-20 patients with confirmed AMI per site during the study period (naturally depending on the size of the hospital). The start of the study is planned for Spring 2022. The aim of the study is to identify the incidence of AMI and its different forms in adult hospitalized patients, and to describe patient characteristics (demographic, clinical and laboratory) at baseline, applied diagnostics and management, as well as outcomes in patients with AMI. An additional aim is to compare the baseline characteristics and outcomes of patients with confirmed AMI to those of patients with suspected AMI in whom the diagnosis was not confirmed.
