Brief Summary:

Glutamine is a major fuel for the intestinal tract and immune cells and therefore affects the intestinal permeability (IP) and infection rate at critically ill patients. The preferential route of glutamine supplementation at critically ill patients still remains open. Therefore the researchers will investigate IP, infection rate and treatment outcome at patients supplemented with either parenteral or enteral glutamine.

A prospective randomized single blind study is performed at mechanically ventilated. Patients were randomly assigned to either parenteral (group P) or enteral (group E) glutamine supplemented group. Early enteral feeding is started in both groups. Patients are/will be treated with glutamine for five days. IP will be measured using lactulose/mannitol test (L/M) on the fourth day.

Primary Outcome Measures :
  1. Intestinal Permeability - Lactulose-mannitol(L/M)Test [ Time Frame: 4 days after admission to intensive care unit ]

    Measurement of intestinal permeability using lactulose-mannitol test (L/M test).

    Intestinal permeability to sugars is an accurate test for detecting intestinal damage. Intestinal permeability of the epithelium to very small sugar molecules such as lactulose/mannitol may give useful information regarding the overall condition of the digestive tract.

    Mannitol is absorbed transcellularly and lactulose has a paracellular route of absorption. Reduction in mannitol absorption shows reduced surface area and increased lactulose absorption indicates a leaky gut.

    Lactulose and mannitol are given orally and later determined from the collected urine with HPTLC (high performance thin layer chromatography). The L/M ratio, as a result of lactulose-mannitol tests, is then calculated regarding urine lactulose and mannitol concentrations.

    Thus, with the lactulose/mannitol test the intestinal permeability changes due to different reasons can be evaluated.

Secondary Outcome Measures :
  1. Infection Rate at Participants in Both Groups [ Time Frame: participants were followed for the duration of ICU stay (average 3 weeks) ]
    Number of infections that occured at participants during study.

  2. 6-month Survival [ Time Frame: 6 month ]
    Six month follow up
