Filter by:Acute mesenteric ischemia (AMI) is a severe condition that might occur after cardiovascular surgery. Several risk factors for AMI, such as multimorbidity, the use of vasopressors, and an increase in inflammatory markers have been identified in the past. However, these risk factors also seem to influence the blood and urine levels of I-FABP. This prospective pilot study intends to evaluate the value of perioperatively assessed I-FABP levels and to correlate these values with clinical or angiographic findings in mesenteric ischemia to improve a standardised diagnosis.
Acute mesenteric ischemia (AMI) is a notorious disease with a high mortality, the diagnostic and management is truly multidisciplinary, and the aim of this study is to analyse the results of the patients admited with an AMI in Hospital de Mar.
Current study will be undertaken to identify combinations of biomarkers that can reliably identify acute mesenteric ischaemia (AMI) and distinguish between non-transmural and transmural ischaemia. Different combinations of biomarkers for different sub-types and severity of AMI, and different time points of measurement after onset of symptoms.
Guidelines on the acute and long-term pharmacological treatment of acute mesenteric ischaemia (AMI) recommend the use of thrombolytic, antiplatelet or anticoagulant therapy depending on the aetiology of AMI and the use of stenting but only few details are given on the choice of the drug, dose and duration of treatment. Besides, recommendations are mainly based on data on coronary, cerebral and other peripheral artery diseases and do also not take into account the altered drug absorption in patients with short bowel syndrome, in which AMI can result.This case-based survey will inform us on the current international clinical practice of long-term antithrombotic management of AMI.
To investigate a number of blood based parameters in patients with intestinal ischaemia compared to patients with other acute abdominal diseases.
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.
Rationale: Acute intestinal ischemia is a life-threatening condition with a short-term mortality that can range up to 80%. Medical diagnosis and treatment have remained troublesome, due to the clinical presentation which is mostly characterized by non-specific signs and symptoms. Early unambiguous diagnosis of acute intestinal ischemia is critical to prevent progression from reversible to irreversible intestinal injury, and henceforth decrease morbidity and improve survival. Objective: We aim to validate a panel of plasma biomarkers and investigate volatile biomarkers that allow early and accurate identification of acute intestinal ischemia in patients. In addition, we aim to identify a volatile organic compound (VOC) profile specific for acute intestinal ischemia in exhaled breath. Study design: Prospective observational study Study population: All patients suspected of acute intestinal ischemia Main study parameters: The primary endpoint of the study is the early and accurate identification of presence and severity of acute intestinal ischemia in patients. The main study parameters are plasma biomarkers indicative for intestinal damage and volatile organic compounds (VOC) in exhaled air of patients suspected of acute intestinal ischemia. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: There is a minimal amount of risks involved in participating in this study. Blood samples will be obtained with the use of an arterial line, intravenous line (IV), central venous catheter (CVC), peripheral venous catheter (PVC) or a venepuncture. The risk of venepuncture is a small local hematoma. In addition to blood sampling, we will also obtain exhaled air. This non-invasive procedure takes approximately 5 minutes in which patients breath in a 3L Tedlar bag at a normal frequency and volume. This procedure will not cause any physical strain. Collection of samples and data will take place during the hospital stay of the included patients. For this reason, no additional hospital visits are required for this study. Participating patients in this study will have no direct benefits, but in the future the results of our study will likely be useful in the early diagnosis of patients suspected of acute intestinal ischemia. The research goal in this study is the early identification of patients that suffer from acute intestinal ischemia. These patients are difficult to diagnose due to a multitude of non-specific symptoms and the lack of fast and specific tests. In this study we will be able to investigate patients that are admitted with acute abdominal complications and observe them in the early stages of their condition. Accordingly, we will be able to evaluate the proposed panel of biomarkers and to identify VOC patterns in patients with acute abdominal complications.
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.
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.
Acute mesenteric ischemia is a life-threatening condition characterized by high mortality if unrecognized early. This multicenter retrospective observational study will review the emergency departments's (ED) notes of all patients discharged from hospital with a diagnosis of acute mesenteric ischemia in 2014-2015 comparing it with those admitted to the ED for abdominal pain in the same timeframe.
