Citrulline genration test before starting enteral nutrition
At ICU admission, a blood sample is collected (i) before and (ii) 90 minutes after N2-L-Alanyl-L-Glutamine administration

Enteral Nutrition

Intensive Care Unit

Biomarkers

20 gr of 10% N2-L-Alanyl-L-Glutamine, dilution in 200 ml of water for injection, intravenous perfusion over 30 minutes

N2-L-Alanyl-L-Glutamine (Substance)

Citrullinemia for the Prediction of Enteral Nutrition Tolerance Among Critically Ill Patients

Feeding intolerance evaluated at day-3 of enteral nutrition Citrulline generation test: variation of citrullinemia/90 minutes

Feeding intolerance at day-3 of enteral nutrition Citrullinemia measured the first day just before initiation of enteral nutrition

Link between citrullinemia and cumulative amount of enteral nutrition administred during the first three days of ICU stay

Link between citrullinemia levels and occurrence of acute mesenteric ischemia and inhalation pneumopathy during the first week of enteral nutrition

Centre Hospitalier Universitaire de Besancon

A bolus of Dipeptiven (Glutamine-Alanine) administered intravenously over 30 minute (20 gramme of N2-L-Alanyl-L-Glutamine solution, dilution in 200 ml of water for injection, intravenous perfusion over 30 minutes).

patients with confirmed diagnosis of acute MVT on CT scan but having no signs of peritonitis or established CT signs of gangrene will be treated conservatively with anticoagulation(heparin &warfarin) while other cases will be for surgical management and not included in the study.

patients who underwent conservative therapy with anticoagulation (heparin &warfarin) but showed no improvement .

Mesenteric Vein Thrombosis

Patients with confirmed diagnosis of acute MVT but having no signs of bowel infarction will be treated conservatively with anticoagulation (heparin &warfarin) In addition to usual care intravenous low molecular weight heparin will be started (IV bolus of 5000 IU followed by 1000 IU/hour with infusion pump) and the dose is adjusted to maintain APTT levels at 2-2.5 times the normal. followed by oral anticoagulation (warfarin) for 6 months or for life in the presence of coagulation abnormality. patients will be critically monitored for the progress of response of therapy .

Warfarin

patients managed conservatively with anticoagulation will be monitored for the progress of response of therapy , failure to improve or worsening in condition,will be an urgent indication for surgical intervention with resection of the infarcted bowel segment .If there is suspicion about the viability of remaining bowel intraoperative or later on based on clinical evidences,then" second look" laparotomy will be performed .The mortality and all complications associated with surgery will be recorded.

MVT with failure of anticoagulation therapy

Heparin

Acute Mesenteric Venous Thrombosis.. in Assiut University Hospital Management Controversies

patients with confirmed diagnosis of acute MVT on CT scan will be treated conservatively In addition to usual care such as fluid and electrolyte balance, antibiotic coverage and nasogastric intubation ,intravenous heparin will be started and the dose is adjusted to maintain APTT levels at 2-2.5 times the normal. followed by oral anticoagulation (warfarin) for 6 months or for life in the presence of coagulation abnormality. All patients will be critically followed up(Clinically.. Radiologically ) for the progress of response of therapy , failure to improve or worsening in condition( appearance of signs of peritonitis such as guarding, rigidity and fever...or radiological signs of bowel infarction) will be assessed .
Factors that may affect the response such as ( age, duration from onset of the disease till starting therapy,underlying diseases,.. )also complications (hemorrhage, failure ,..)will be assessed

number of recurrent cases post conservative therapy .

number of deaths as a complication of conservative therapy or surgery

Diagnosis of acute MVT will be based on clinical presentation &positive CT scan.(9) .patients with confirmed diagnosis of acute MVT on CT scan but having no signs of peritonitis or established CT signs of gangrene will be treated conservatively .(11)In addition to usual care ,intravenous heparin will be started and the dose is adjusted to maintain APTT levels at 2-2.5 times the normal. (12) followed by oral anticoagulation (warfarin) for 6 months or for life in the presence of coagulation abnormality. All patients will be critically monitored for the progress of response of therapy , failure to improve or worsening in condition,will be an urgent indication for surgical intervention with resection of the infarcted bowel segment .If there is suspicion about the viability of remaining bowel intraoperative or later on based on clinical evidences,then" second look" laparotomy will be perfomed .The mortality and all complications associated with surgery will be recorded.
