• Resumen

  • Introduction: Previous studies have found that L-arginine induced beneficial effects over insulin resistance both in type 2 diabetes mellitus patients and healthy individuals. The aim of our study was to investigate whether an L-arginine enteral supplementation (20 g per day) in head and neck cancer patients could modify insulin resistance, leptin and adiponectin levels after surgery.

    Material and Methods: At surgery 82 patients were randomly allocated to two groups: group I received an enteral diet supplements with a high dose of arginine (20g per day) and group II received an enteral formula without arginine. At basal time and on postoperative day 10, the following parameters were recorded: glucose, c-reactive protein, insulin, HOMA (homeostasis model assessment), leptin and adiponectin.

    Results: Values of weight, body mass index, fat mass and fat free mass remained unchaged during the acute nutritional intervention in both groups. Insulin levels UI/L (-0.21+/-0.18) and HOMA units (-0.07+/-0.13) decreased in the arginine group. Adiponectin levels (+1.8+/-2.3ng/ml) increased in the arginine group.

    Conclusion: Short-term enteral L-arginine therapy addeded to usual enteral nutrition of patients affected by head and neck cancer and surgery without diabetes mellitus type 2 is able to improve insulin resistance and adiponectin levels.
