Abstract
PURPOSE l-arginine (L-arg) deficiency causes immunosuppression, but it is unknown if L-arg supplementation in colorectal cancer (CRC) patients restores immune system activity. Our objective was to investigate the effect of L-arg supplementation on the frequency of monocytic (M) and polymorphonuclear (PNM) myeloid-derived suppressor cells (M-MDSCs and PMN-MDSCs, respectively). METHODS We enrolled 65 CRC patients (34 males, 31 females) aged 69 ± 10 years into a prospective, randomised, double-blind study. Twenty-eight patients received L-arg and 37 received placebo for 9 days at a dose of 10 g/day. The frequency changes in MDSC, CD4+ cells and the concentration of C-reactive protein (CRP) were assessed before supplementation with L-arg (test 1), after 9 days of supplementation (test 2), and after surgery on day 11 (test 3). RESULTS The frequency of M-MDSC in the tumours of patients receiving L-arg supplementation was higher than in placebo-treated patients, as was the frequency of PMN-MDSC and M-MDSC in the mucosa. CRP concentration in the serum of placebo-treated patients in test 2 was higher than in test 1, and the concentration in the serum of patients with L-arg supplementation in test 2 was lower than in test 1. Moreover, the expression pattern of the argininosuccinate synthase 1 (ASS1) suggests that CRC is not auxotrophic for L-arg. CONCLUSIONS The results of this study do not support the hypothesis that L-arg supplementation in CRC patients can reduce immunosuppression by decreasing the frequency of suppressor cells and increasing the frequency of effector CD4+ T cells.

Abstract
Overweight and obese individuals may have leaky intestinal barrier and microbiome dysbiosis. The aim of this study was to determine whether body mass reduction with diet and synbiotics in an adult person with excess body mass has an influence on the gut microbiota and zonulin concentration. The study was a single blinded trial. 60 persons with excess body mass were examined. Based on randomization, patients were qualified either to the intervention group (Synbiotic group) or to the control group (Placebo group). Anthropometric measurements, microbiological assessment of faecal samples and zonulin concentration in the stool were performed before and after observation. After 3-months, an increase in the variety of intestinal bacteria (increase in the Shannon-Weaver index and the Simpson index) and a decrease in concentration of zonulin in faecal samples were observed in the Synbiotic group. Also, statistically significant correlation between zonulin and Bifidobacterium spp. (Spearman test, R=-0.51; p=0.0040) was noticed. There were no significant relationships between the body mass, BMI and changes in the intestinal microbiota or zonulin concentrations. The use of diet and synbiotics improved the condition of the microbiota and intestinal barrier in patients in the Synbiotic group.

Abstract
Leptin is an important factor regulating appetite and energety metabolism; disturbances in its signaling are related to adiposity and contribute to the excessive body fat. About a third of the human population is overweight or suffers from obesity, as well as from associated medical conditions. It is well established that vegetarian, especially vegan, diet is very effective in lowering BMI and body fat, thus, plant-based diets are associated with a lower risk of obesity. The aim of this study was to evaluate the plasma levels of leptin in lacto-ovo-vegetarian and vegan volunteers with normal BMI. The intake of energy and selected diet components such as polyunsaturated fatty acids (PUFA) and carbohydrates was also investigated. The study involved healthy women - 14 omnivores, 17 lacto-ovo-vegetarians, and 11 vegans. All women had a normal BMI (18.5-24.99). The plasma leptin levels were examined with immunoenzymatic test (ELISA). All participants were interviewed to estimate their nutrient intake by performing a 24-hour dietary recall. Both lacto-ovo-vegetarians and vegans had lower plasma leptin concentrations than their meat-consuming counterparts. Every analyzed diet group had a different body fat content, with the highest level in omnivores and the lowest in vegans. All participants had similar calorie, total fat, and total carbohydrates intake. Total PUFA and specifically omega-3 fatty acids consumption was lower in omnivores when compared to both types of plant diet; the same was found for fiber intake. Our results suggest that adopting a plant-based diet may be beneficial for energetic metabolism, as it significantly lowers the body fat storage and circulating leptin levels.

Abstract
Cardiovascular (CVS) morbidity and mortality in the peritoneal dialysis patients (PD) is 10-30-fold higher than in the general population. A relatively low level of adiponectin and a higher level of leptin are important predictors of vascular complications as well as CVS events in PD patients. The asymmetric dimethylarginine (ADMA), an endogenous inhibitor of nitric oxide synthase, is an important risk factor of CVS morbidity and mortality. It is very important to establish all CVS risk factors in the PD patients to prevent CVS morbidity and mortality in this population. The aim of the study was to determine the plasma concentration of ADMA and adipokines in relation to the protein-energy wasting (PEW) in PD patients. The study was performed in 30 PD patients and in the control group which consisted of 23 healthy volunteers. Plasma levels of hsC-reactive protein, TNF, IL-6, leptin, adiponectin, oxyLDL and ADMA were measured by ELISA method in both groups. The nutritional status was determined by measuring the albumin, body mass index (BMI), the percentage of body fat (%F), lean body mass (LBM) and Subjective Global Assessment Score (SGA). The adequacy of dialysis was estimated by weekly Kt/V. In all PD patients, significantly higher levels of ADMA, leptin, oxyLDL, hsCRP and TNF in comparison to controls were observed. In contrast to well-nourished subjects, patients with PEW, in addition to increased hsCRP, showed significantly higher ADMA. PEW was associated with high levels of ADMA and hsCRP and this could probably be responsible for increased CVS risk in PD patients.

Abstract
BACKGROUND Iron is one of the nutrients that require special consideration in a plant-based diet. The widespread belief is that meat is the best source of iron and a vegetarian diet increases the risk of its deficiency. This conviction has been the subject of analysis in a growing number of scientific reports. OBJECTIVES The aim of this study was to assess the iron intake and iron metabolism in vegetarians and vegans compared to a control group. MATERIAL AND METHODS A total of 55 vegetarians and 36 healthy volunteers were studied. The following parameters were measured in serum: iron, ferritin, transferrin, transferrin receptor, and hepcidin-25, using the enzyme-linked immunosorbent assay (ELISA) method. The dietary iron intake was assessed by a 24-h dietary recall. RESULTS The mean daily intake (DI) of iron was significantly higher in the female vegan group compared to the control group. Iron, hepcidin-25, ferritin and transferrin receptor in serum remained within their normal ranges. The ferritin concentration was significantly decreased and that of transferrin significantly higher in both female groups and in the male vegan group. CONCLUSIONS The obtained results show that the studied parameters, excluding transferrin, remained within normal ranges. However, the ferritin concentration was significantly decreased in the female vegetarian group and also in both vegan groups. This may indicate low iron storage.

Abstract
Severe aortic stenosis (AS) is associated with the reduction of muscle mass and may be associated with deterioration of nutritional status. Furthermore, malnourished cardiac patients are characterized by a higher risk of postoperative complications and mortality. The aim of this study was the evaluation and comparison of nutritional status, appetite and body composition in older people with severe aortic stenosis before aortic valve replacement and healthy elderly volunteers. One hundred and one patients, aged >65 years old with severe AS were included in the study. Nutritional status was assessed. Body composition was estimated using bioelectrical impedance analysis. Concentrations of albumin, prealbumin, triglycerides, total cholesterol and C-reactive protein were measured, and a complete blood count was done. About 40% of AS patients were at risk of malnutrition. They had decreased hand grip strength and they lost more body mass than the control group. Malnourished AS patients were older, had lower body mass indexes (BMIs) and lower aortic valve areas in comparison to well-nourished patients. Older AS patients, like their peers, show excessive body mass and, at the same time, the features of malnutrition. They have additional factors such as unintentional weight lost and decreased muscle strength which may be associated with worse outcomes.

Abstract
BACKGROUNDː The mechanisms underlying the metabolic effect of surgical treatment for morbid obesity are still unclear. Furthermore, the hormonal and metabolic response to the promising and less-invasive version of Roux-en-Y gastric bypass (RYGB), i.e. mini gastric bypass (MGB), is poorly known. The aim of this study was to evaluate pre- and postprandial changes in peptide YY (PYY) and metabolic parameters in obese patients without diabetes and cardiovascular complications treated by both versions of gastric bypass. METHODSː Venous blood for PYY and other assays was collected three months before and six months after bariatric operation (MGB and RYGB), in the fasting state and two hours after the consumption of a standard 300-kcal mixed meal (Nutridrink Standard, Nutricia Advanced Medical Nutrition, part of the Danone company, Schiphol, The Netherlands). RESULTSː In the MGB group, elevated concentrations of the PYY has been detected both fasting and postprandially. The effect of the MGB on the PYY levels did not differ from the RYGB group outcomes. CONCLUSIONSː The results of our study suggest similar endocrine and metabolic effects of MGB and RYGB procedures. Long-term efficacy and metabolic benefits of MGB require further research.

Abstract
PURPOSE Pharmacological inhibition of the renin-angiotensin-aldosteron system (RAAS) may have a beneficial impact on proteinuria and chronic kidney diseases (CKD) progression. Despite recent progress by means of angiotensin-converting enzyme inhibitors (ACEI) and angiotensin II receptor blockers (ARB), there is still no optimal therapy which can stop progression of the nephropathy. Recently introduced aliskiren is the first orally bioavailable direct renin inhibitor approved for the treatment of hypertension. The purpose was to evaluate the extent of oxidative stress and tubular injury after the direct renin inhibitor, aliskiren compared with placebo and perindopril in patients with non-diabetic chronic kidney disease (NDCKD). MATERIAL/METHODS A randomized, double-blind, cross-over trial was performed in 14 patients receiving 300mg aliskiren, 10mg perindopril and placebo in random order. The end point was a change in the urinary excretion of N-acetyl-β-D-glucosaminidase (NAG) and α1-microglobulin (α1m) and 15-F(2α)-isoprostane. RESULTS Aliskiren reduced excretion of 15-F(2α)-isoprostane (p=0.03) and α1m (p=0.01) as compared to placebo. There were no differences between aliskiren and perindopril in this regard. NAG urine excretion did not change after aliskiren and perindopril. CONCLUSIONS Aliskiren attenuates oxidative stress and may improve functional status of tubules in patients with NDCKD.

Abstract
Cancer cachexia (CC), a progressive loss of body mass, is associated with decreased energy production. Abnormally low levels of L-carnitine (LC) in skeletal muscle means that mitochondrial β-oxidation of long-chain fatty acids (LCFA) does not occur efficiently in patients with CC. We assessed the influence of CC on LC distribution and the effects of parenteral lipid emulsions on plasma LC levels and urinary excretion. Fifty patients with CC were randomly assigned to total parenteral nutrition (TPN) with long-chain triglycerides (LCTs), or LCTs plus medium-chain triglycerides (MCTs) as 50/50. Patients were further separated into those with body-mass index (BMI) ≤ 19 kg/m(2) and BMI >19 kg/m(2). Plasma concentrations of total LC (TC) and free LC (FC) and their urinary excretion were measured, along with skeletal muscle LC levels. On average, plasma FC and TC were higher than reference values in all patients. Patients with BMI ≤ 19 kg/m(2) had lower plasma FC and TC than those with BMI >19 kg/m(2). Skeletal muscle FC in the BMI ≤ 19 kg/m(2) group was lower than reference value, but within the normal range in others. LC and FC urinary excretion was higher than reference values. Plasma LC and its urinary excretion were higher in patients administered pure LCTs relative to those given MCTs/LCTs. A decrease in skeletal muscle LC in cancer patients with CC (BMI ≤ 19 kg/m(2)) correlates with an increase in its plasma levels and increased renal excretion. A diet of MCTs/LCTs reduces LC release from muscle to plasma and urine more effectively than LCTs.

Abstract
In this study, the levels of ischemia-modified albumin (IMA) in pediatric oncology patients with soft tissue sarcomas (STSs) and neuroblastoma (NB) were analyzed. To date, there have been no studies concerning IMA in these groups of patients. Ninety-nine children with STSs and NB were analyzed from 2006 to 2009, and 30 healthy children were also enrolled in the study. IMA levels were measured throughout treatment in all patients. The levels of IMA in all cancer patients (mean 116.8±39.3 U/ml), in patients with STSs (mean 119.8±27.5 U/ml), and in patients with NB (mean 114.6±36.6 U/ml) were significantly higher than in the control patients (mean 87.3±38.3 U/ml; P=0.0013, 0.0066, and 0.0164, respectively). IMA levels increased before and during the treatment compared with levels in the controls. The determination of IMA levels in pediatric oncology patients with poor prognoses from STSs and NB may play an important role in predicting response to therapy and overall outcome.

Abstract
BACKGROUND Antioxidant systems in cells maintain the proper homeostasis of reactive oxygen species, which at high concentrations can induce carcinogenesis. The aim of this study was to evaluate the serum levels of ischemia-modified albumin (IMA), erythrocyte superoxide dismutase (SOD), and glutathione peroxidase (GSH-Px) as markers for prognosis in children with neuroblastoma (NB) and soft tissue sarcomas (STS), two cancer types for which reliable prognostic factors are needed. PROCEDURE SOD, GSH-Px, and IMA were measured before and during responses to therapy assessment in 99 children with NB and STS and in 30 healthy controls. RESULTS There were no statistically significant differences in the erythrocyte SOD and GSH-Px activities between the patients with cancer and healthy controls. The levels of IMA in patients with STS and NB were found to be significantly higher than in the controls (P = 0.0013; P = 0.0066, and 0.0164, respectively). Decreased activities of SOD and GSH-Px were found in all patients with poor-responding (PRS) cancers and decreased SOD activity was found in patients with PRS NB. An increase in GSH-Px was observed in patients with good-responding (GR) NB. All patients with GR cancers demonstrated higher SOD and GSH-Px activities than patients with PRS cancers. CONCLUSIONS While determining the levels of specific antioxidants as antioxidant-barrier parameters in children with cancer may be valuable in predicting therapeutic responses as well as outcomes, additional studies are required.

Abstract
AIM Malnutrition is a common clinical problem in dialysis patients. The objective of this study was to evaluate the efficacy and safety of megestrol acetate in malnourished dialysis patients. Thirty-two hypoalbuminemic dialysis patients took 160 mg of megestrol acetate daily for up to 6 months. METHODS We measured height, dry weight, BMI, modified Subjective Global Assessment (SGA) score, and serum albumin, triglycerides, total cholesterol, hsCRP, IL-1β and IL-6 concentrations. We used validated questionnaires to evaluate selected dimensions of the quality of life. RESULTS Only 12 patients completed the study. All patients reported improved appetite, and there were concurrent statistically significant increases in weight, BMI, SGA and albumin concentration (P < 0.05). For the 12 patients who completed 6 months of treatment the increase in these parameters was from 63.26 ± 13.04 to 65.58 ± 12.53 kg, from 23.5 ± 3.8 to 24.66 ± 4.23 kg/m(2), from 5.16 ± 0.94 to 6.16 ± 0.72 points, and from 36.45 ± 1.82 to 40.33 ± 2.71 g/l, respectively. However, there were no significant changes in the levels of inflammatory markers and in quality of life. Side effects included overhydration, excessive weight gain and hyperglycaemia. CONCLUSION Megestrol acetate may be effective in reversing poor appetite in carefully selected maintenance dialysis patients, but it might not reduce inflammation or improve the quality of life. Because of the potential side effects, close monitoring is essential.

Abstract
OBJECTIVE Adipokines such as leptin and adiponectin are adipocyte-specific secretory proteins that play important roles in the metabolic regulation of body weight, insulin resistance and cardiovascular complications. The relationship between the malnutrition-inflammation complex syndrome and high levels of some adipokines in peritoneal dialysis (PD) patients is still unclear. An association between high body mass index (BMI) and improved survival in PD patients has also been proposed. The purpose of this study was to investigate the levels of plasma adipokines and inflammation and oxidative stress markers in overweight and normal weight PD patients. MATERIAL AND METHODS Thirty PD patients (12 M, 18 F; mean age 57.3 ± 16.6 years) were examined and 23 healthy volunteers were included as a control group. The levels of high-sensitivity C-reactive protein (hsCRP), tumour necrosis factor-α, interleukin-6, leptin, the leptin receptor, adiponectin, malondialdehyde/4-hydroxynonenal, oxidized low-density lipoprotein, carbonyl groups and asymmetric dimethylarginine (ADMA) were measured in both groups. The nutritional status of each patient was determined by albumin levels, BMI, percentage of body fat (%F), lean body mass (LBM) and the Subjective Global Assessment (SGA) score. The adequacy of dialysis was estimated by weekly Kt/V measurements. RESULTS According to the seven-point SGA scores and the albumin levels, the nutrition status of 15 patients was good (6-7 points), while 15 patients were mildly malnourished (3-5 points). The concentrations of hsCRP, leptin and adiponectin were statistically higher in the PD group than in the control group (p < 0.05). Markers of oxidative stress and inflammation were also higher in the PD group. The adiponectin level was inversely correlated with %F and BMI (Spearman's R = -0.3, p ≤ 0.05) and positively correlated with hsCRP level (R = -0.4). The level of leptin was positively correlated with %F, BMI and LBM (R = 0.4, p ≤ 0.05). Patients with normal BMI values had lower leptin concentrations (50.2 vs 242.8 μg/l) and higher adiponectin levels (30.0 vs 20.3 μg/ml) than overweight patients. The statistical analysis indicated that there were no differences in oxidative stress, inflammation and ADMA concentration between the lean and overweight PD patients. CONCLUSION The nutritional status of lean and overweight patients was comparable. Signs of malnutrition were detected in both groups. The severity of chronic inflammation and oxidative stress were not related to BMI in PD patients.

Abstract
OBJECTIVES The aim of this study was to investigate the serum concentration of adipokines, such as leptin, adiponectin, and resistin, and assess its relation to nutritional and inflammatory parameters in both overweight and normal weight patients on maintenance hemodialysis. METHODS A total of 36 hemodialysis patients (27 M, 9 F; mean age 55.3 +/- 12 yr.) were examined and 23 additional healthy volunteers were recruited as the control group. The concentrations of leptin, leptin receptor, adiponectin, resistin, IL-6, TNFa and CRP were measured by ELISA. Assessment of nutritional status was determined by the levels of albumin, BMI, percentage of body fat (%F), lean body mass (LBM), and Subjective Global Assessment Score (SGA). RESULTS According to the SGA 7-points score and the albumin level, 20 patients were of good nutritional status (6-7 points), while 16 patients were mildly malnourished (4-5 points). The concentrations of CRP, resistin, adiponectin, and TNFa were statistically higher in hemodialysis patients than in the control group (p pound 0.05). The adiponectin level was inversely correlated with %F (R Spearman=-0.3; p pound 0.05). The level of leptin was positively correlated with %F as well as with BMI and SGA scores (R Spearman=0.4; p pound 0.05). Although there was no significant difference in the nutritional status between the nonoverweight (BMI 18.5-24.99) and overweight (BMI (3)25.0) groups of patients, in the nonoverweight group there were 12 patients (54.5%) with signs of mild malnutrition compared to 4 malnourished patients (28.5%) in the overweight group. Nonoverweight patients presented significantly lower leptin concentration (12.7 vs 27.8 ug/l) and higher adiponectin level (38.9 vs 32.5 ng/ml) when compared to overweight patients. The levels of IL-6 and TNFa were higher in the nonoverweight group of patients. Overweight patients also had shorter durations of stay in the hemodialysis program (30.5 vs. 87.6 months). CONCLUSION The results of our study indicate that lean hemodialysis patients are more prone to malnutrition and inflammation. The increased levels of leptin and decreased levels of adiponectin in the overweight hemodialysis patients support the idea of a reverse epidemiology phenomenon in this group of patients.

Abstract
AIM: To investigate the influence of neutrophil adhesion molecule blockade with monoclonal antibody (MoAb CD11b) and E. coli lipopolysaccharide (LPS) administration on experimental acute pancreatitis (AP).
METHODS: AP was induced by four ip injections of cerulein (Cn) at 1-h intervals. MoAb CD 11b and LPS were administered at the beginning of the experiment.
RESULTS: The neutrophil count and chemiluminescence were diminished at the beginning of AP. The oxidative stress parameters were found within the pancreatic gland. MoAb CD 11b used for AP resulted in a significant reduction of pancreatic infiltration and pancreatitis oxidative stress parameters. Serum interleukin-6 (IL-6) was not detected in AP animals, whereas high serum IL-6 concentration was noted only in animals receiving LPS.
CONCLUSION: Neutrophils are involved in pancreatic damage in the early stage of AP. Neutrophil infiltration reduction protects the pancreatic gland from destruction during AP. LPS does not change the early course of Cn pancreatitis in rats.
