Objective: Lipid emulsions containing omega-3 are known to have positive effects on patient's prognosis due to anti-inflammatory properties. The aim of this study was to investigate the effects of omega-3 enriched total parenteral nutrition (TPN) emulsion containing omega-9 on biochemical parameters, inflammatory mediators in septic patients. Methods: Thirty-two participants who were not fed orally for over five days and needing TPN support were included in this prospective, randomized and double-blind clinical study. Patients were randomly divided into control (n=16), treatment (n=16) groups. The treatment group received TPN containing 80% olive oil+20% soy oil additionally 10 g fish oil enriched TPN. Control group received only olive oil containing standard lipid emulsion (1.3±0.1 g/kg/day). Blood samples were collected for biochemical analysis on the 1st and 6th days of study. Results: The serum albumin levels significantly increased (p<0.05) in both groups whereas total protein and prealbumin levels did not show any significant changes. In treatment group, significant decreases were determined in LTB4 and CRP levels (p<0.05) while decreases in IL-6, TNF-α and leukocyte levels were not significant. No statistically significant changes were found in LTB4, CRP, IL-6, TNF-α and leukocyte levels of controls. Conclusion: Results of the study have shown that omega-3 enriched TPN solution containing omega-9 contributes to decrease in the levels of inflammatory mediators and to improvement in the biochemical parameters in septic patients.
Aim: This study was performed to determine the effects of glutamine enriched total parenteral nutrition (TPN) on the patients with acute pancreatitis (AP). Method: Forty patients with AP, who had Ranson's score between 2 and 4 received either standard TPN (control group) or TPN with glutamine (treatment group). The patients in the treatment group received TPN containing 0.3 g/kg/days glutamine. At the end of the study, patients were evaluated for nutritional and inflammatory parameters, length of TPN and length of hospital stay.Results: The length of TPN applications were 10.573.6 days and 11.672.5 days, and the length of hospital stays were 14.274.4 and 16.473.9 days for the treatment and control groups (NS), and the complication rates in the treatment and control groups were 10 and 40%, respectively (Po0.05). The transferrin level increased by 11.7% in the group that received glutamine-enriched TPN (Po0.05), whereas the transferrin level decreased by 12.1% in the control group (NS). At the end of the study, slight but not significant changes were determined in both groups in fasting blood sugar, albumin, blood urea nitrogen (BUN), creatinine, total cholesterol concentrations, aspartate aminotransferase (AST), alanine transaminase (ALT) and lactate dehydrogenase (LDH) activities, leukocytes, CD 4 , CD 8 , serum Zn, Ca and P levels compare to the baseline levels (NS). Significant decreases were determined in serum lipase, amylase activities and C-reactive protein (CRP) levels in both groups (Po0.05). Conclusions:The results of this study have shown that glutamine supplementation to TPN have beneficial effects on the prevention of complications in patients with AP.
This study was performed to investigate the serum zinc (Zn), plasma ghrelin, leptin levels and nutritional status, and to evaluate the potential association between malnutrition and these investigated parameters in malnourished hemodialysis (HD) patients. Fifteen malnourished HD patients, aged 42.9 +/- 2.11 years, who underwent the HD for 46.44 +/- 7.1 months and 15 healthy volunteers, aged 41.0 +/- 2.17 years, were included in this study. The nutritional status of the subjects was determined by the subjective global assessment (SGA). Anthropometric measurements were taken by bioelectrical impedance after HD. Blood samples were collected for the analysis of zinc (Zn), ghrelin, leptin, and selected blood parameters. The HD patients consumed less energy and nutrients than controls. In HD patients, body weight, body mass index (BMI) (p < 0.001), basal metabolic rate (BMR), body fat, lean body mass (LBM), serum Zn, copper (Cu) (p < 0.05), sodium (Na) (p < 0.01), glucose (p < 0.05), albumin (p < 0.01), total cholesterol (p < 0.001), and ghrelin (p < 0.05) were lower whereas body water ratio (p < 0.001), serum potassium (K) (p < 0.01), inorganic phosphorous (Pi), blood urea nitrogen, creatinine (p < 0.001), and plasma insulin (p < 0.05) levels were higher than the controls. No difference existed between HD patients and controls regarding plasma leptin levels. There were positive correlations for body weight-fasting glucose and body weight-leptin (p < 0.05), body weight-BMI and body weight-LBM (p < 0.01); body fat-leptin (p < 0.05); BMI-fasting glucose, BMI-leptin, and BMI-body fat (p < 0.05); albumin-hemoglobin and albumin-insulin (p < 0.05). Negative correlation was found for SGA score-ghrelin (p < 0.05). Malnutrition in HD patients may result from inadequate energy and nutrient intake and low Zn and ghrelin levels. Zinc supplementation to the diets of HD patients may be of value to prevent the malnutrition.
