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).

intake of 5g glutamine and 10g maltodextrin. Oral glutamine is a food additive issued by food and drug government in Taiwan with number 009929.L-Glutamine and maltodextrin are both nutritional supplements. In the glutamine arm: 10 g L-Glutamine and 5 g maltodextrin.
The patients take their supplements three times a day during the period: 7 days before radiotherapy to 14 days after radiotherapy.

intake of 15g maltodextrin. The patients take their supplements three times a day during the period: 7 days before radiotherapy to 14 days after radiotherapy.

Head and Neck Cancer

L-Glutamine and maltodextrin are both nutritional supplements. In the glutamine arm: 10 g L-Glutamine and 5 g maltodextrin. The patients take their supplements three times a day during the period: 7 days before radiotherapy to 14 days after radiotherapy.

oral glutamine

in the placebo arm: 15 g maltodextrin. The patients take their supplements three times a day during the period: 7 days before radiotherapy to 14 days after radiotherapy.

placebo

All patients undergo radiotherapy. 5 days a week. All patients had a dental evaluation for good oral hygiene prior to computed tomography simulation for radiotherapy. Post-operative patients received planned course of adjuvant treatment of 60 to 66 Gy in 2-Gy fractions to the surgical bed. The course of radiation was initiated no more than 6 weeks after resection. Patients without operation received definitive treatment to 70 Gy in 2-Gy fractions.

Effects of Oral L-Glutamine in Head and Neck Cancer Patients During Radiotherapy

Impacts of Oral Supplement With L-Glutamine on the Radiation-induced Toxicity and Nutritional Status of Head and Neck Cancer Patients Under Radiotherapy

Oral mucositis and radiation-induced dermatological toxicity were evaluated during and after treatment using the National Cancer Institute Common Toxicity Criteria version 3.0 (CTCAE v.3). The scoring was done as the patients went through the treatment by the attending physicians. Post-operative patients received planned course of adjuvant treatment of 60 to 66 Gy in 2-Gy fractions to the surgical bed. Patients without operation received definitive treatment to 70 Gy in 2-Gy fractions.
