EFFECTS OF STANDARD AND/OR GLUTAMINE DIPEPTIDE AND/OR OMEGA-3 FATTY ASCID-SUPPLEMENTED PARENTERAL NUTRITION ON...

Area of Science:

• Oncology
• Immunology
• Nutritional Science

Background:

• Protein-calorie malnutrition impairs immune function in cancer patients.
• Colorectal cancer patients often experience malnutrition, affecting their immunity.
• Altered cellular and humoral immunity are common in malnourished cancer patients.

Purpose of the Study:

• To compare the effects of standard TPN, TPN with glutamine, TPN with omega-3 fatty acids, and TPN with both on neutrophil function and IL-8 levels in colorectal cancer patients.
• To evaluate the impact of specific nutritional interventions on immune markers in malnourished colorectal cancer patients.
• To determine if omega-3 fatty acids and glutamine supplementation can improve immune status in this patient group.

Main Methods:

• 36 malnourished colorectal cancer patients were randomly assigned to four groups receiving different TPN formulations.
• Interventions included standard TPN, TPN with glutamine, TPN with omega-3 fatty acids, or TPN with both.
• Neutrophil phagocytosis index, neutrophil adhesivity index, and IL-8 levels were measured preoperatively and postoperatively.

Main Results:

• Neutrophil phagocytosis index significantly increased in all intervention groups compared to the control group.
• Neutrophil adhesivity index showed no significant difference on postoperative day one but increased in intervention groups by day seven.
• Interleukin-8 (IL-8) levels did not differ significantly among the groups.

Conclusions:

• Omega-3 fatty acid emulsions and glutamine supplementation added to TPN can correct altered cellular immunity in malnourished colorectal cancer patients.
• These nutritional interventions hold potential for reducing morbidity and mortality rates.
• Targeted nutritional therapy can positively impact immune status and clinical outcomes in cancer patients.
