Detailed Description
Glutamine is the most abundant amino acid in the body constituting 50% to 60% of total free amino acid pool in muscle and 20% in plasma. Recently it has been reclassified as a conditionally essential amino acid due to body's inability to synthesize sufficient amount under stressful conditions like trauma and sepsis. It is an essential fuel for fibroblasts, lymphocytes and enterocytes. It plays an important role in nitrogen balance and an integral role in glucose regulation and also in acid base homeostasis. It is an essential ingredient for glutathione, an important antioxidant. During the last decade a number of experimental and clinical studies, by using enteral and parenteral glutamine supplements, have shown its beneficial role in conditions like sepsis and infection, elective surgery and accidental injury, catabolic state, fetal and critically ill low birth weight neonates and cancer. A few experimental and clinical studies have also shown its positive role in inflammatory bowel disease, which is attributed to the effect of glutamine on intestinal permeability, growth of enterocytes, enhancement of gut immunity and glutathione synthesis. So far there is hardly any well-planned randomized trial of enteral glutamine supplements in Crohn's disease. Hence this study is planned to evaluate effect of enteral glutamine supplements on structure and function of intestine in patients with Crohn's disease.
Diagnosed cases of Crohn's Disease attending Gastroenterology OPD or admitted in ward at AIIMS will be randomized into two groups, glutamine and whey protein group. The parameters for intestinal function and structure tested will be, permeability, villous height, plasma glutamine and D-xylose absorption at the base line and at the end of the intervention. As per the available data improvement is expected in both structure and function of the intestine, which will be an important contribution in the management of this chronic disease.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: Glutamine
Glutamine would be supplemented (0.5gm/Kg ideal body weight) in the form of a water soluble commercial preparation containing 10 gm of pure L- Glutamine in the crystalline form.
The patient in this group would be counseled to meet the remaining protein requirement (i.e1g/Kg/wt) by usual diet.
This intervention would be made over a period of two months.

Placebo Comparator: Whey Protein
Whey Protein: Whey protein would be supplemented (0.5gm/Kg ideal body weight) in the form of a water soluble whey protein concentrate containing 70 % protein. The patient in this group would be counseled to meet the remaining protein requirement (i.e1g/Kg/wt) by usual diet. This intervention would be made over a period of two months. |
