Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
During critical illness the demand for glutamine is increased. Rapid depletion of glutamine stores in critically ill patients has been described and correlated to increased mortality. Glutamine depletion may be deleterious in critical illness because of adverse effects on the essential functions mentioned above. For example glutamine depletion may cause gut mucosal barrier function to deteriorate, leading to bacterial translocation and enhanced systemic inflammatory response with increased risk for multisystem organ failure. Clinical trials performed in a wide range of patients with serious illness, including cancer, trauma, burn, major surgery and critical illness, have demonstrated possible benefits of glutamine supplementation. Interpretation of the results of multiple studies is made difficult based on differences in glutamine dosing, route of administration, population studied, and endpoints used.
Blood volume analysis has been shown to be a good measure of capillary leak. The DAXOR blood volume analyzer kit was recently approved by the FDA for blood volume analyses and also has the capacity of measuring capillary permeability by looking at the slope of albumin transudation. It is a simpler way to measure capillary permeability than other methods described.
Reviewing the previous study results, glutamine supplementation in parental form and with higher dose in various patient populations has shown evidence of being beneficial. Studies of enteral glutamine therapy have also showed benefits, but results are less consistent possibly because of the heterogeneous study methodology described above. Moreover, most of the studies are carried out in burn patients and surgical patients; there were few studies in critical ill medical patients. Finally no study has specifically looked at the mechanism via which glutamine has conferred protection.
Comparison: Critically ill patients given enteral tube feeds compared to critically ill patients given enteral tube feeds with supplemental glutamine.
