NCT07303153
Acute mesenteric ischemia is a severe abdominal emergency associated with a poor prognosis. While numerous studies have been conducted on the incidence, outcomes, and risk factors of mesenteric ischemia, very few focus on the quality of life of patients.
NCT06869564
Acute mesenteric ischemia (AMI) is associated with high mortality (50-80%). The prognosis depends on the time it takes to diagnose the condition, and the possibility of revascularization in eligible patients. Delayed diagnosis is due in particular to the aspecific clinical presentation and the absence of biomarkers to guide early diagnosis, lactates often being elevated at an already irreversible stage. Adenosine deaminase is produced in the presence of ischemia (known from myocardial ischemia), and is present on the surface of intestinal villi. The investigator's hypothesis is that, in the event of digestive ischemia resulting in abnormalities of mesenteric permeability, adenosine deaminase will enter the bloodstream and increase its soluble plasma activity, along with an increase in lymphocyte-bound adenosine deaminase. The main objective is to evaluate the discriminatory capacities of soluble adenosine deaminase, collected via blood sampling, for the diagnosis of IMA in comparison with the reference method (injected abdominopelvic CT scan), performed for abdominal pain suggestive of IMA. The study will be based on a prospective monocentric cohort. Currently, there is no specific biological marker for IMA, and the gold standard for diagnosis is the injected abdominopelvic CT scan, performed for hyperintense abdominal pain. Two groups will be identified on the basis of the gold-standard abdominopelvic scan: * the "IMA patients" group: patients with hyperintense abdominal pain, and IMA confirmed by CT scan * the "non-IMA patients" group: patients with hyperintense abdominal pain, but with a diagnosis other than IMA on the CT scan. 130 subjects will be included in this study Inclusion period: 18 months Follow-up period: 1 month Analysis period: 5 months Total duration: 24 months
NCT06507423
This study will help determine whether the SeptiCyte LAB test can accurately differentiate between SIRS and actual infections in postoperative patients, potentially reducing unnecessary antibiotic use and improving patient outcomes in cases of acute mesenteric ischemia
NCT06445660
Computed tomography (CT) is the standard modality for scanning patients with critical acute abdominal conditions, including suspected acute mesenteric ischemia (AMI). CT imaging can potentially differentiate between reversible and irreversible ischaemic damage of the bowel. This moment is pivotal in selecting the treatment strategy for AMI - in the absence of irreversible damage; reperfusion therapy can preserve intestinal viability, thereby avoiding the need for bowel resection. The present study tests the hypothesis that combining several symptoms may enhance the diagnostic performance of CT scanning in detecting salvageable bowel in patients with AMI. This study is an ancillary component of the AMESI study (Clinical Trials: NCT05218863) - a prospective, multicentre observational study aimed at identifying the incidence and describing the outcomes of acute mesenteric ischemia (AMI) in adult hospitalized patients. The ultimate purpose of the present study is to create a computed tomography-based radiological score for the assessment of bowel viability in patients with AMI.
NCT06428240
Acute mesenteric ischaemia (AMI) is a notorious disease with a high mortality, the diagnostic and management is truly multidisciplinary, but not very extended. The aim of this study is to analyse the results of the patients admited with an AMI in Catalonia.
NCT05706012
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.
NCT02772913
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.
NCT01788904
In the FARAMIS study, we aim to investigate the longitudinal course of intestinal plasma fatty acid binding protein (i-FABP) in patients with acute mesenteric ischemia (AMI) undergoing primary percutaneous angiographic intervention. The investigators postulate that patients with fully re-established intestinal blood flow and vital intestines will display a significant drop of plasmatic i-FABP within 24 hours, while patients requiring subsequent intestinal resection due to irreversible bowel necrosis will not. If true, patients requiring laparotomy and bowel resection could be identified and patients in whom angiographic intervention led to successful cure of disease would not be exposed to potentially perilous surgery.
