Abstract
BACKGROUND & AIMS Cirrhosis is associated with insulin resistance and impaired glucose tolerance, which may be caused by impairments at different tissue levels (liver, skeletal muscle, and/or beta cell). METHODS Here, glucose kinetics at whole-body and skeletal muscle level in patients with cirrhosis (Child-Pugh A and B) were studied during parenteral nutrition using the isotope dilution technique and arteriovenous balance approach across the leg. As opposed to the euglycemic hyperinsulinemic clamp or glucose tolerance tests applied in previous studies, this approach provides a nutrient composition more similar to a normal meal while circumventing any possible portal-systemic shunting, impaired hepatic uptake and incretin effect. RESULTS We confirmed the presence of hepatic and peripheral insulin resistance in our patient population. Endogenous glucose production was less suppressed in response to parenteral nutrition. However, glucose uptake in skeletal muscle was increased. CONCLUSION Our results suggests that in our study participants with cirrhosis, the hepatic and peripheral insulin resistance is compensated for by increased insulin secretion and thus, increased glucose uptake in muscle. Hereby, glucose homeostasis is maintained.

Pathophysiological-Based Nutritional Interventions in Cirrhotic Patients with Sarcopenic Obesity: A State-of-the-Art Narrative Review. Nutrients 2024; 16:427. [PMID: 38337711 PMCID: PMC10857546 DOI: 10.3390/nu16030427] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/08/2023] [Revised: 01/23/2024] [Accepted: 01/25/2024] [Indexed: 02/12/2024] Open
Abstract
In recent decades, following the spread of obesity, metabolic dysfunction has come to represent the leading cause of liver disease. The classical clinical presentation of the cirrhotic patient has, therefore, greatly changed, with a dramatic increase in subjects who appear overweight or obese. Due to an obesogenic lifestyle (lack of physical activity and overall malnutrition, with an excess of caloric intake together with a deficit of proteins and micronutrients), these patients frequently develop a complex clinical condition defined as sarcopenic obesity (SO). The interplay between cirrhosis and SO lies in the sharing of multiple pathogenetic mechanisms, including malnutrition/malabsorption, chronic inflammation, hyperammonemia and insulin resistance. The presence of SO worsens the outcome of cirrhotic patients, affecting overall morbidity and mortality. International nutrition and liver diseases societies strongly agree on recommending the use of food as an integral part of the healing process in the comprehensive management of these patients, including a reduction in caloric intake, protein and micronutrient supplementation and sodium restriction. Based on the pathophysiological paths shared by cirrhosis and SO, this narrative review aims to highlight the nutritional interventions currently advocated by international guidelines, as well as to provide hints on the possible role of micronutrients and nutraceuticals in the treatment of this multifaceted clinical condition.

Abstract
Sarcopenia and frailty are frequent in cirrhosis, and both contribute to increased morbidity and mortality. The complex pathogenesis of sarcopenia in cirrhosis is mainly determined by hyperammonemia and malnutrition. Sarcopenia/frailty screening and reevaluation should be undertaken in all cirrhotic patients. Frailty tests are useful in the ambulatory setting, whereas the computed tomography scan is the diagnostic gold standard for sarcopenia. To manage sarcopenia/frailty, a multidisciplinary team should develop a personalized comprehensive care plan that includes patient education, protein/calorie intake goals, late evening meals, exercise programs, and micronutrient replenishment. In selected patients, branched-chain amino acid and testosterone supplements may also be beneficial.

Abstract
INTRODUCTION AND OBJECTIVES Appropriate nutritional support may improve energy metabolism in alcoholic liver cirrhosis (ALC) patients. We explored the effect of a late evening snack (LES) and oral amino acid (OAA) capsules on energy metabolism and the Fischer ratio in ALC. PATIENTS AND METHODS Ninety-one ALC patients were enrolled and randomly divided into three groups: 31 patients in the LES and OAA group, 32 in the LES group, and 28 controls. Respiratory quotient (RQ), carbohydrate oxidation rate (CHO%), fat oxidation rate (FAT%), serum isoleucine and the Fischer ratio were measured at baseline and at months 1, 3, and 6 of follow-up. RESULTS The RQ in the LES and OAA group was 0.79 ± 0.06, 0.80 ± 0.04, 0.82 ± 0.04, and 0.82 ± 0.04 at baseline and at months 1, 3, and 6 of follow-up, respectively. These values were significantly higher than those in the LES group (P < 0.05). The RQ in the LES group was significantly higher than that in the control group at month 1 and month 6 (P < 0.05). CHO% in the LES and OAA group was significantly increased and FAT% was significantly decreased at month 3 of follow-up (P < 0.05). In the LES and OAA group, serum isoleucine and the Fischer ratio were markedly increased compared with the LES group and control group (P < 0.05). CONCLUSIONS LES can significantly increase the RQ in ALC. LES and OAA were more effective than LES alone in improving serum isoleucine and the Fischer ratio.

Abstract
Liver cirrhosis is an increasing public health threat worldwide. Malnutrition is a serious complication of cirrhosis and is associated with worse outcomes. With this review, we aim to describe the prevalence of malnutrition, pathophysiological mechanisms, diagnostic tools and therapeutic targets to treat malnutrition. Malnutrition is frequently underdiagnosed and occurs-depending on the screening methods used and patient populations studied-in 5-92% of patients. Decreased energy and protein intake, inflammation, malabsorption, altered nutrient metabolism, hypermetabolism, hormonal disturbances and gut microbiome dysbiosis can contribute to malnutrition. The stepwise diagnostic approach includes a rapid prescreen, the use of a specific screening tool, such as the Royal Free Hospital Nutritional Prioritizing Tool and a nutritional assessment by dieticians. General dietary measures-especially the timing of meals-oral nutritional supplements, micronutrient supplementation and the role of amino acids are discussed. In summary malnutrition in cirrhosis is common and needs more attention by health care professionals involved in the care of patients with cirrhosis. Screening and assessment for malnutrition should be carried out regularly in cirrhotic patients, ideally by a multidisciplinary team. Further research is needed to better clarify pathogenic mechanisms such as the role of the gut-liver-axis and to develop targeted therapeutic strategies.

Abstract
Malnutrition and sarcopenia are common in patients with chronic liver disease and are associated with increased risk of decompensation, infections, wait-list mortality and poorer outcomes after liver transplantation. Assessment of nutritional status and management of malnutrition are therefore essential to improve outcomes in patients with chronic liver disease. This consensus statement of the Indian National Association for Study of the Liver provides a comprehensive review of nutrition in chronic liver disease and gives recommendations for nutritional screening and treatment in specific clinical scenarios of malnutrition in cirrhosis in adults as well as children with chronic liver disease and metabolic disorders.

Abstract
Background: The relationship of leptin (LEP) and polymorphism of leptin receptor (LEPR) were studied in patients with hepatocellular carcinoma (HCC) and compared with those with liver cirrhosis to find out the extent of the risk of LEPR on patients with HCC. Methods: Serum LEP level and LEPR Q223R gene polymorphism were determined in 300 patients with liver disease categorized equally into five groups’ healthy volunteers, patients with hepatitis C (HCV), patients with non-alcoholic steatohepatitis (NASH), liver cirrhosis and HCC. LEPR gene was amplified by polymerase chain reaction (PCR) then digested by the MSP1 restriction enzyme. Results: The isolated 212 bp of LEPR was sequenced. The serum LEP level was reduced in patients with cirrhotic and HCC. Serum LEP level had negatively correlated with both tumor grade and size in HCC patients. The data obtained from restriction fragment length polymorphismPCR and sequencing revealed the existence of a novel synonymous Q223R single nucleotide polymorphism (SNP) in exon 223 of LEPR gene (1137101). LEPR Gln223Arg, GG and GA genotypes were found in all studied groups. LEPR Gln223Arg, AA genotype was found in NASH, HCC, and control. LEPR Gln223Arg GA genotype is associated with some patients with HCC. Conclusion: GA genotype of LEPR Gln223Arg may be regarded as a probable genetic risk factor for Egyptian patients with HCC.

Abstract
Malnutrition is highly prevalent in liver cirrhosis and its presence carries important prognostic implications. The clinical conditions and pathophysiological mechanisms that cause malnutrition in cirrhosis are multiple and interrelated. Anorexia and liver decompensation symptoms lead to poor dietary intake; metabolic changes characterised by elevated energy expenditure, reduced glycogen storage, an accelerated starvation response and protein catabolism result in muscle and fat wasting; and, malabsorption renders the cirrhotic patient unable to fully absorb or utilise food that has been consumed. Malnutrition is therefore a considerable challenge to manage effectively, particularly as liver disease progresses. A high energy, high protein diet is recognised as standard of care, yet patients struggle to follow this recommendation and there is limited evidence to guide malnutrition interventions in cirrhosis and liver transplantation. In this review, we seek to detail the factors which contribute to poor nutritional status in liver disease, and highlight complexities far greater than "poor appetite" or "reduced oral intake" leading to malnutrition. We also discuss management strategies to optimise nutritional status in this patient group, which target the inter-related mechanisms unique to advanced liver disease. Finally, future research requirements are suggested, to develop effective treatments for one of the most common and debilitating complications afflicting cirrhotic patients.

Abstract
BACKGROUND Malnutrition/sarcopenia and frailty are common in patients with cirrhosis and are associated with poor outcomes. AIM To provide an overview of data on the importance, assessment and management of malnutrition/sarcopenia and frailty in cirrhosis. METHODS A literature search was conducted in PubMed and other sources, using the search terms "sarcopenia," "muscle," "malnutrition," "cirrhosis," "liver" and "frailty" from inception to April 2019, to identify the relevant studies and international guidelines. RESULTS The prevalence of malnutrition/sarcopenia in cirrhosis is 23%-60%. Frailty generally overlaps with malnutrition/sarcopenia in cirrhosis, leading to increased morbidity and mortality. Rapid nutritional screening assessment should be performed in all patients with cirrhosis, and more specific tests for sarcopenia should be performed in those at high risk. The pathogenesis of malnutrition/sarcopenia in cirrhosis is complex/multifactorial and not just reduction in protein/calorie intake. Hyperammonemia appears to be the main driver of sarcopenia in cirrhosis through several molecular signalling pathways. Nutritional management in malnourished patients with cirrhosis should be undertaken by a multidisciplinary team to achieve adequate protein/calorie intake. While the role of branched-chained amino acids remains somewhat contentious in achieving a global benefit of decreasing mortality- and liver-related events, they, and vitamin supplements, are recommended for those with advanced liver disease. Novel strategies to reverse sarcopenia such as hormone supplementation, long-term ammonia-lowering agents and myostatin antagonists, are currently under investigation. CONCLUSIONS Malnutrition/sarcopenia and frailty are unique, inter-related and multi-dimensional problems in cirrhosis which require special attention, prompt assessment and appropriate management as they significantly impact morbidity and mortality.

Abstract
A frequent complication in liver cirrhosis is malnutrition, which is associated with the progression of liver failure, and with a higher rate of complications including infections, hepatic encephalopathy and ascites. In recent years, the rising prevalence of obesity has led to an increase in the number of cirrhosis cases related to non-alcoholic steatohepatitis. Malnutrition, obesity and sarcopenic obesity may worsen the prognosis of patients with liver cirrhosis and lower their survival. Nutritional monitoring and intervention is therefore crucial in chronic liver disease. These Clinical Practice Guidelines review the present knowledge in the field of nutrition in chronic liver disease and promote further research on this topic. Screening, assessment and principles of nutritional management are examined, with recommendations provided in specific settings such as hepatic encephalopathy, cirrhotic patients with bone disease, patients undergoing liver surgery or transplantation and critically ill cirrhotic patients.

Abstract
BACKGROUND Liver cirrhosis induces marked metabolic disorders, protein-energy malnutrition, and sarcopenia. The objective of the study reported here was to investigate the effects of dietary branched-chain amino acids (BCAAs) on systemic glucose metabolism, skeletal muscle, and prognosis of patients with liver cirrhosis. METHODS Japanese patients with liver cirrhosis (n = 21) were enrolled into a longitudinal study in which their diets were supplemented with BCAAs. We evaluated glucose metabolism and analyzed the skeletal muscle area index (SAI) and intramuscular adipose tissue content (IMAC) using computed tomography. RESULTS After 48 weeks of supplementation with BCAAs, there were no changes in glucose metabolism and skeletal muscle findings. In patients with ameliorated hypoalbuminemia, IMAC was significantly decreased and SAI was preserved concomitant with decreasing 90- and 120-min post-challenge plasma glucose levels (P < 0.01 each). In patients without increased albumin levels, IMAC was significantly increased and the SAI was significantly decreased (P < 0.01 each). Liver-related event-free survival rates for 72 months were 63.6% in patients with decreased IMAC and 20.0% in patients with increased IMAC. CONCLUSIONS Amelioration of hypoalbuminemia associated with BCAA supplementation correlated with decreased fat accumulation in skeletal muscle, maintenance of skeletal muscle mass, and improved glucose sensitivity, all factors which may contribute to improving the survival of patients with liver cirrhosis.

Abstract
Purpose of Review Nutritional status in patients with cirrhosis is very frequently associated with macro- and micronutrient deficiencies. Cirrhosis itself is the cause of malnutrition and nutritional deficiencies but these conditions have to be identified and addressed properly as they can worsen the prognosis of cirrhosis. The goals of this review are to 1) identify and describe the challenges associated with nutritional assessment in cirrhosis and 2) describe recent advancements when using clinical, laboratory, and instrumental tools in the evaluation of malnourished patients with liver diseases. Recent Findings The most promising tools for nutritional assessment in cirrhosis include the evaluation of body composition with phase angle obtained by bioelectrical impedance analysis, computed tomography transverse images at the level of third lumbar vertebra. The Royal-Free Hospital global assessment algorithm appears to be helpful but needs further validation. Summary Nutritional assessment in cirrhosis is challenging as several factors, including edema, can interfere with it and because of lack of a validated gold standard. Regardless, nutritional assessment methods have been developed in recent years and should gain relevance in the clinical practice.

Abstract
OBJECTIVE Hypermetabolism in cirrhosis is associated with a high risk of complications and mortality. However, studies about underlying mechanisms are usually focussed on isolated potential determinants and specific etiologies, with contradictory results. We aimed at investigating differences in nutrition, metabolic hormones, and hepatic function between hypermetabolic and nonhypermetabolic men with cirrhosis of the liver. PATIENTS AND METHODS We prospectively enrolled 48 male cirrhotic inpatients. We evaluated their resting energy expenditure (REE) and substrate utilization by indirect calorimetry, body composition by dual-energy X-ray absorptiometry, liver function, and levels of major hormones involved in energy metabolism by serum sample tests. Patients with ascites, specific metabolic disturbances, and hepatocellular carcinoma were excluded. RESULTS REE and REE adjusted per fat-free mass (FFM) were significantly increased in cirrhotic patients. Overall, 58.3% of cirrhotic patients were classified as hypermetabolic. Groups did not differ significantly in age, etiology of cirrhosis, liver function, presence of ascites, use of diuretics, β-blockers, or presence of transjugular intrahepatic portosystemic shunts. Hypermetabolic cirrhotic patients had lower weight, BMI (P<0.05), nonprotein respiratory quotient (P<0.01), leptin (P<0.05), and leptin adjusted per fat mass (FM) (P<0.05), but higher FFM% (P<0.05) and insulin resistance [homeostatic model assessment-insulin resistance (HOMA-IR)] (P<0.05). Only HOMA-IR, leptin/FM, and FFM% were independently related to the presence of hypermetabolism. CONCLUSION Hypermetabolic cirrhotic men are characterized by lower weight, higher FFM%, insulin resistance, and lower leptin/FM when compared with nonhypermetabolic men. HOMA-IR, FFM%, and leptin/FM were independently associated with hypermetabolism, and may serve as easily detectable markers of this condition in daily clinical practice.

Abstract
Patients with liver cirrhosis exhibit several features of gut dysfunction which may contribute to the development of cirrhosis complications as well as have an impact on nutritional status and health-related quality of life. Gastrointestinal symptoms are common in cirrhosis and their pathophysiology probably involves factors related to liver disease severity, psychological distress, and gut dysfunction (e.g., increased gastric sensitivity to distension and delayed gut transit). They may lead to reduced food intake and, thus, may contribute to the nutritional status deterioration in cirrhotic patients. Although tense ascites appears to have a negative impact on meal-induced accommodation of the stomach, published data on gastric accommodation in cirrhotics without significant ascites are not unanimous. Gastric emptying and small bowel transit have generally been shown to be prolonged. This may be related to disturbances in postprandial glucose, insulin, and ghrelin levels, which, in turn, appear to be associated to insulin resistance, a common finding in cirrhosis. Furthermore, small bowel manometry disturbances and delayed gut transit may be associated with the development of small bowel bacterial overgrowth. Finally, several studies have reported intestinal barrier dysfunction in patients with cirrhosis (especially those with portal hypertension), which is related to bacterial translocation and permeation of intestinal bacterial products, e.g., endotoxin and bacterial DNA, thus potentially being involved in the pathogenesis of complications of liver cirrhosis.

Abstract
The liver is the major organ for the metabolism of protein, fat and carbohydrate. A nutritional approach is required in the treatment of cirrhosis, which is frequently complicated with protein-energy malnutrition. Several advanced treatment approaches for hepatocellular carcinoma (HCC) have been established in the past decade. HCC is often complicated by cirrhosis, so treatment of the underlying liver diseases is also necessary to improve the prognosis. Branched-chain amino acid (BCAA) granules were developed originally for the treatment of hypoalbuminemia associated with decompensated cirrhosis. However, subsequent studies found various other pharmacological actions of this agent. We review the clinical significance of therapy using BCAA granules in patients receiving different treatment approaches for cirrhosis and HCC based on the published work as well as our own data.

Abstract
AIM In patients with chronic liver disease who are at risk of malnutrition, simple and useful assessments for nutritional status should be established for ordinary medical care. The prognostic nutritional index (PNI) and controlling nutritional status (CONUT) are simple assessments constructed of only two or three laboratory data. We aimed to describe the potential of PNI and CONUT as a nutritional assessment tool in patients with chronic liver disease. METHODS We enrolled 165 patients, aged 18-85 years, with chronic liver disease. These patients were nutritionally assessed by PNI or CONUT, demonstrating the association with the severity of chronic liver disease or anthropometric values. RESULTS The value of PNI or CONUT was significantly associated with the severity of chronic liver disease (P < 0.001, respectively). In addition, the value of CONUT was significantly associated with all the anthropometric values such as body mass index (BMI, P < 0.05), mid-arm circumference (AC, P < 0.001), mid-arm muscle circumference (AMC, P < 0.001), and triceps skinfold thickness (TSF, P < 0.001), whereas the value of PNI was significantly associated with the values of AC (P < 0.01), AMC (P < 0.05) and TSF (P < 0.05). Approximately 80% of cirrhotic patients were assessed by PNI or CONUT to have obvious malnutrition. CONCLUSION PNI and CONUT are potential tools for nutritional assessment in patients with chronic liver disease, especially for ordinary medical care, because of their simplicity.

Abstract
BACKGROUND/PURPOSE Malnutrition and metabolic disorder of patients undergoing living donor liver transplantation (LDLT) can affect post-transplant prognosis. The aim of this study was to establish whether perioperative usage of branched-chain amino-acid (BCAA)-enriched nutrients improve metabolic abnormalities of patients undergoing LDLT. METHODS We designed a randomized pilot study (UMIN registration number; 000004323). Twenty-five consecutive adult elective LDLT recipients were enroled and divided into two groups: the BCAA group (BCAA-enriched nutrients, n = 12) and the control group (standard diet, n = 13). Metabolic and nutritional parameters, including BCAA-to-tyrosine ratio (BTR), retinol binding protein (RBP), and prealbumin were regularly measured from 1 week before to 4 weeks after LDLT. Non-protein respiratory quotient (npRQ) was measured before and 4 weeks after LDLT. RESULTS BTR and RBP improved considerably in the BCAA group compared with the controls. npRQ significantly increased from 1 week before LDLT to 4 weeks after LDLT in the BCAA group (0.77 ± 0.05 to 0.84 ± 0.06, P = 0.002), but not in the control group (0.78 ± 0.04 to 0.81 ± 0.05). CONCLUSIONS Supplementation with BCAA-enriched nutrients might improve persistent nutritional and metabolic disorders associated with end-stage liver disease in the early post-transplant period, and consequently shorten the post-transplant catabolic phase after LDLT. A larger multicenter trial is needed to confirm these findings.

Abstract
AIM: To assess the nourishment status and lifestyle of non-hospitalized patients with compensated cirrhosis by using noninvasive methods.
METHODS: The subjects for this study consisted of 27 healthy volunteers, 59 patients with chronic viral hepatitis, and 74 patients with viral cirrhosis, from urban areas. We assessed the biochemical blood tests, anthropometric parameters, diet, lifestyle and physical activity of the patients. A homeostasis model assessment-insulin resistance (HOMA-IR) value of ≥ 2.5 was considered to indicate insulin resistance. We measured height, weight, waist circumference, arm circumference, triceps skin-fold thickness, and handgrip strength, and calculated body mass index, arm muscle circumference (AMC), and arm muscle area (AMA). We interviewed the subjects about their dietary habits and lifestyle using health assessment computer software. We surveyed daily physical activity using a pedometer. Univariate and multivariate logistic regression modeling were used to identify the relevant factors for insulin resistance.
RESULTS: The rate of patients with HOMA-IR ≥ 2.5 (which was considered to indicate insulin resistance) was 14 (35.9%) in the chronic hepatitis and 17 (37.8%) in the cirrhotic patients. AMC (%) (control vs chronic hepatitis, 111.9% ± 10.5% vs 104.9% ± 10.7%, P = 0.021; control vs cirrhosis, 111.9% ± 10.5% vs 102.7% ± 10.8%, P = 0.001) and AMA (%) (control vs chronic hepatitis, 128.2% ± 25.1% vs 112.2% ± 22.9%, P = 0.013; control vs cirrhosis, 128.2% ± 25.1% vs 107.5% ± 22.5%, P = 0.001) in patients with chronic hepatitis and liver cirrhosis were significantly lower than in the control subjects. Handgrip strength (%) in the cirrhosis group was significantly lower than in the controls (control vs cirrhosis, 92.1% ± 16.2% vs 66.9% ± 17.6%, P < 0.001). The results might reflect a decrease in muscle mass. The total nutrition intake and amounts of carbohydrates, protein and fat were not significantly different amongst the groups. Physical activity levels (kcal/d) (control vs cirrhosis, 210 ± 113 kcal/d vs 125 ± 74 kcal/d, P = 0.001), number of steps (step/d) (control vs cirrhosis, 8070 ± 3027 step/d vs 5789 ± 3368 step/d, P = 0.011), and exercise (Ex) (Ex/wk) (control vs cirrhosis, 12.4 ± 9.3 Ex/wk vs 7.0 ± 7.7 Ex/wk, P = 0.013) in the cirrhosis group was significantly lower than the control group. The results indicate that the physical activity level of the chronic hepatitis and cirrhosis groups were low. Univariate and multivariate logistic regression modeling suggested that Ex was associated with insulin resistance (odds ratio, 6.809; 95% CI, 1.288-36.001; P = 0.024). The results seem to point towards decreased physical activity being a relevant factor for insulin resistance.
CONCLUSION: Non-hospitalized cirrhotic patients may need to maintain an adequate dietary intake and receive lifestyle guidance to increase their physical activity levels.

Abstract
BACKGROUND Nutrition management of cirrhosis in hospitalized patients is overlooked despite the clinical significance of sarcopenia or loss of muscle mass in cirrhosis. Determining optimal nutrition requirement needs precise measurement of resting energy expenditure (REE) in the cirrhotic patient. Predictive equations are not accurate, and the metabolic cart is expensive and cumbersome. The authors therefore performed a prospective study to examine the feasibility and accuracy of a handheld respiratory calorimeter (HHRC) in quantifying the REE in hospitalized cirrhotic patients not in the intensive care unit. MATERIALS AND METHODS The study was done in 2 phases: in the first phase, the REE of 24 consecutive healthy volunteers was measured using an HHRC in different positions. The objective of this phase was to identify the impact of body and arm position on measured REE. Subsequently, in the second phase of the study, REE was measured using the HHRC and the metabolic cart in 25 consecutive well-characterized, hospitalized cirrhotic patients. The degree of concordance was calculated. RESULTS Body position and arm position did not significantly affect the measured REE using HHRC. In patients with cirrhosis, the mean measured REE (kcal/d) using the HHRC was 1453.2 ± 319.3 in the hospital room, 1525.6 ± 305.2 in a quiet environment, and 1553.7 ± 270.6 with the metabolic cart (P > .1). Predicted REE using 2 widely used equations did not correlate either with each other or with the measured REE. CONCLUSIONS HHRC is a valid, feasible, and rapid method to determine optimal caloric needs in hospitalized cirrhotic patients.

Abstract
The rapid development of molecular biology has provided new paths for and led to great breakthroughs in the treatment of liver fibrosis. Now the research of targets for anti-fibrosis therapy mainly focuses on hepatic stellate cells (HSC) and cytokines related to HSC activation. Researchers are getting more concerned about the features of nutritional metabolism in patients with liver fibrosis and their relationship with prognosis because of special roles the liver plays in nutritional metabolism. Reasonable principles of nutritional support can help ameliorate symptoms, reduce complications and facilitate recovery in patients with liver fibrosis.

Acylated ghrelin is the biologically active form that modifies insulin sensitivity and body composition. The aim of the present study was to compare acylated and total ghrelin concentration in patients with liver cirrhosis and to investigate the possible relationship between ghrelin and clinical and nutritional parameters. DESIGN AND METHODS Sixty patients with viral liver cirrhosis who did not have hepatocellular carcinoma or acute infections were studied. Twenty healthy volunteers were recruited after matching for age, gender, and body mass index with the patients and served as controls. Fasting levels of total, acylated ghrelin, leptin, TNF-alpha and insulin were measured in all subjects, in addition, clinical and nutrition parameters were assessed. RESULTS In cirrhotic patients, plasma levels of both acylated and total ghrelin were significantly higher than those in the controls. The mean plasma acylated ghrelin levels were significantly higher in Child C cirrhosis compared to Child A and B. Ghrelin (total and acylated) were negatively correlated with leptin in cirrhotic patients confirming the fact that leptin acts as a physiological counterpart of ghrelin. CONCLUSIONS Nutritional and metabolic abnormalities in cirrhotic patients may be dependent on the changes in the ghrelin/leptin systems, mainly the acylated form of ghrelin.

Abstract
OBJECTIVE Patients with liver disease usually have an imbalanced nutrient and energy metabolism that leads to malnutrition and seriously affects their prognosis. Therefore, it is of great clinical interest to understand the resting energy expenditure (REE) and oxidation rates of glucose, fat, and protein in these patients. METHODS A total of 315 patients with liver diseases caused by hepatitis B virus were categorized into three groups: 20 acute hepatitis patients, 142 chronic hepatitis patients and 153 liver cirrhosis patients. The REE and the oxidation rates of glucose, fat and protein were assessed by indirect heat measurement. Energy intake data were also collected which were compared with the REE results. RESULTS The REE per kg (REE/kg) were 27.34 ± 5.46 kJ/kg, 21.67 ± 5.01 kJ/kg and 19.07 ± 4.45 kJ/kg in acute, chronic hepatitis and liver cirrhosis patients (p=0.000), respectively. Respiratory quotient (RQ) tended to be lower in patients with chronic hepatitis and liver cirrhosis than that in acute hepatitis patients (p=0.023). Energy, protein and carbohydrate intakes were lower in liver cirrhosis patients. CONCLUSION These data demonstrated that Chinese patients with chronic hepatitis B and liver cirrhosis had lower energy expenditure and abnormal substrate metabolism. Patients with chronic hepatitis and cirrhosis had a higher protein oxidation rate and a lower carbohydrate oxidation rate compared with acute hepatitis patients.

Abstract
BACKGROUND The malnutrition is a frequent finding in adults with cirrhosis, but the prevalence of nutritional risk and malnutrition is little known in pediatric patients. AIM To evaluate through anthropometry the presence of nutritional risk and malnutrition in cirrhotic pediatric patients regularly attended at the Pediatric Gastroenterology Service of "Hospital de Clínicas" of Porto Alegre, RS, Brazil. METHODS Cross-sectional study with 42 cirrhotic children and adolescents aged between 3 months and 18 years. The nutritional evaluation was made by the determination of the weight/age, height/age, body mass index and triceps skinfold thickness and arm muscle circumference measurements. Patients considered in nutritional risk were < or = -1,28 Z score which corresponds to < or = 10th percentile, and those under -2,0 Z and < or = 3th percentile were in malnutrition status. According to Child-Pugh criteria, 22 patients were classified as A (mild severity), 15 (moderate) B and 5 C (intense). RESULTS The mean weight/age, height/age and body mass index Z scores were, respectively, - 0,38 +/- 1,4 SD, - 0,83 +/- 1,16 SD and 0,17 +/- 1,3 SD. Patients in nutritional risk were 3/42 (weight/age), 8/42 (height/age), 12/37 (triceps skinfold thickness), 9/37 (arm muscle circumference), 2/38 (body mass index); in malnutrition status were 6/42 (weight/age), 7/42 (height/age), 4/37 (triceps skinfold thickness) and 4/37 (arm muscle circumference) and 3/38 (body mass index). CONCLUSION The prevalence of nutritional risk was 32.4% and chronic malnutrition was 16.7%. The index which better reflected the nutritional risk in these patients was triceps skinfold thickness. Chronic malnutrition status occurrence was greater in the height/age index.

Abstract
BACKGROUND Liver cirrhosis is associated with reduced energy intake and increased resting energy expenditure. OBJECTIVE We aimed to investigate the possible role of glucose, insulin, leptin, and ghrelin in the pathogenesis of these alterations. DESIGN Nutritional status, energy intake, resting energy expenditure, and fasting glucose, insulin, and leptin were assessed in 31 patients with cirrhosis. Postprandial glucose, insulin, C-peptide, leptin, and ghrelin responses were studied in a subgroup of patients after a standard meal. Ten healthy subjects served as controls. RESULTS Patients with cirrhosis had a lower energy intake (P < 0.05), higher resting energy expenditure (P < 0.05), higher fasting leptin (P < 0.05), and higher insulin resistance (P < 0.001) than did the healthy control subjects. In the patients with cirrhosis, fasting leptin was negatively correlated with resting energy expenditure (r = -0.38, P < 0.05) but not with energy intake. In control subjects, leptin was negatively correlated with energy intake (r = -0.72, P < 0.05) but not with resting energy expenditure. The patients with cirrhosis had higher postprandial glucose (P < 0.001) and lower ghrelin (P < 0.05) concentrations at 4 h postprandially than did the control subjects. The increase in ghrelin from its minimal postmeal value to 4 h postmeal was negatively correlated (r = -0.66, P = 0.014) with weight loss in the patients with cirrhosis. Energy intake was negatively correlated (r = -0.42, P < 0.01) with the postprandial increase in glucose. CONCLUSIONS In cirrhosis, altered postprandial glucose and ghrelin are associated with reduced energy intake and weight loss, respectively, and the effects of leptin on energy intake and expenditure seem to be altered. Insulin resistance might be involved in these altered postprandial responses.

Abstract
AIM: To evaluate the role of leptin levels in the differential diagnosis of ascites.
METHODS: Ascitic leptin, TNFα and serum leptin levels were measured in 77 patients with ascites (35 with malignancies, 30 cirrhosis and 12 tuberculosis). Control serum samples were obtained from 20 healthy subjects. Leptin and TNFα levels were measured by ELISA. Body mass index (BMI) and percentage of body fat (BFM) by skin fold measurement were calculated for all patients and control groups. Peritoneal biopsy, ascites cytology and cultures or biochemical values were used for the diagnosis of patients.
RESULTS: In patients with malignancies, the mean serum and ascites leptin levels and their ratios were significantly decreased compared to the other patient groups and controls. In tuberculosis peritonitis, ascitic fluid TNFα levels were significantly higher than malignant ascites and cirrhotic sterile ascites. BMI and BFM values did not distinguish between patients and controls.
CONCLUSION: In patients with malignant ascites, levels of leptin and TNFα were significantly lower than in patients with tuberculous ascites.

Abstract
Patients with end-stage liver disease (ESLD) frequently have diverse abnormalities of carbohydrate, lipid, and protein metabolism that cause progressive deterioration of their clinical condition and lead to malnutrition. Malnutrition is almost universally present in patients with ESLD undergoing liver transplantation and has been associated with increased morbidity and mortality. It is essential to identify and correct nutritional deficiencies in this population and provide an adequate nutritional support during all phases of liver transplantation. In conclusion, this article reviews the etiologic factors, prevalence, assessment and management guidelines of nutritional disorders seen in patients with ESLD undergoing liver transplantation.

Abstract
Our aim was to measure whole body energy expenditure after a mixed liquid meal, with and without simultaneous propranolol infusion, in patients with cirrhosis. We also wanted to investigate the effect of propranolol on substrate fluxes and oxygen uptake in the tissues drained by the hepatic vein and azygos vein in the postprandial period in these patients. Whole-body oxygen uptake, hepatic blood flow, hepatic venous pressure gradient and net-hepatic fluxes of oxygen, lactate, glucose, glycerol, and free fatty acids (FFA) were measured in 12 patients with alcoholic cirrhosis before and for 2 h after ingestion of a mixed liquid meal (700 kcal). Half of the patients (n = 6) were randomized to a treatment group receiving intravenous infusion of propranolol in combination with the meal. The meal-induced energy expenditure was significantly lower in patients given propranolol [15.0 +/- 18.9 vs. 67.0 +/- 26.1 kJ/120 min (means +/- SD), P < 0.01]. Meal-induced whole body oxygen uptake was lower in patients receiving propranolol (19.2 +/- 38 vs. 135.7 +/- 61 mmol/120 min, P < 0.01), and the meal-induced increase in splanchnic oxygen uptake was nonexistent when propranolol was administered in combination (-13.2 +/- 34.8 vs. 110.4 +/- 34.8 mmol/120 min, P = 0.04). Postprandially, the propranolol group had a tendency toward a reduced splanchnic glucose output, and the FFA uptake was significantly reduced. Propranolol reduces meal-induced whole body oxygen uptake and energy expenditure as well as splanchnic oxygen uptake. The splanchnic reduction in oxygen consumption can explain almost the entire reduction in whole body oxygen consumption.

Abstract
Monitoring of respiratory gas exchange in humans is an important task in order to establish the physical condition of the patient and to control important physiological indices. In a previous work, we proposed an approximated linear dynamical model of gas exchange within a controlled volume, to be used as a basis for Kalman filtering technique in order to improve the accuracy of the estimates. In this paper, we propose an alternative nonlinear dynamical model of the same phenomenon and suggest the use of a nonlinear estimation technique. A simulation study demonstrates that operative conditions exist where the latter results are more accurate than the estimates based on the linear model. A set of controlled experiments are also designed in order to create situations in which the above difference is significant. In the paper it is evidenced that, in different operative conditions, the analysis both of simulated and experimental data, give systematically the same indications about the choice of the filtering method. The conclusive result of this paper is that a nonlinear model, and the corresponding nonlinear estimation technique, turn out to be convenient when the operative volume and the accuracy of the instrumentation of the experimental set up are both low (operative volumes of about ten liters and flows measurements errors with variances not less than 1 [liter/min]2). It should be also remarked that the proposed model-based estimation techniques, both linear and nonlinear, are highly superior to conventional methods used in medical practice. The present study provides insights and guidelines that can also be useful when dealing with similar gas exchange estimation problems in many other different application areas.

Abstract
PURPOSE OF REVIEW The aim of this paper is to describe the relevant medical literature published between spring 2003 and spring 2005 in the field of malnutrition in liver disease and its management. RECENT FINDINGS The most relevant articles covered in this paper provide data regarding the absence of energy imbalance in patients with stable cirrhosis, thus arguing against its potential role in the development of malnutrition; the increase in body cell mass and muscle mass as the major components of weight gain after portal-systemic shunting; the largest published randomized controlled trial of the positive effect of branched-chain amino acid supplements on the long-term outcome of patients with cirrhosis; studies using stable isotope labeled substrates, suggesting that dietary fat could be absorbed via the portal vein in patients with cirrhosis; and a randomized controlled trial suggesting the possibility that probiotics may decrease the infection rate after liver transplantation. SUMMARY In spite of the data provided by these and other articles described in the review, the major controversial issues in the field of nutritional management of liver disease remain open. Particularly remarkable is the lack of consensus regarding the nutritional management of acute liver failure.

Abstract
Diurnal variations of adiponectin levels have been studied in normal-weight men and in diabetic and nondiabetic obese subjects, but no data have been reported in obese subjects after weight loss. We collected blood samples at 1-h intervals over 24 h from seven severely obese subjects before and after massive weight loss consequent to surgical operation (bilio-pancreatic diversion [BPD]) to measure adiponectin, insulin, glucose, and cortisol levels. Insulin sensitivity was assessed by euglycemic-hyperinsulinemic clamp (M value). Studies of diurnal variations and pulsatility of adiponectin, insulin, and cortisol were performed. The pulsatility index (PI) of adiponectin increased after BPD from 0.04 to 0.11 microg/min (P = 0.01). Insulin PI significantly increased after the operation (1.50 vs. 1.08 pmol.l(-1).min(-1), P = 0.01), while cortisol PI did not significantly change. The adiponectin clearance rate changed from 0.001 +/- 10(-4).min(-1) before BPD to 0.004 +/- 8. 10(-4).min(-1) after BPD (P = 0.03). Insulin clearance increased from 0.006 +/- 6. 10(-4).min(-1) before BPD to 0.009 +/- 4.10(-4). min(-1) after BPD (P = 0.02). The M value doubled after surgery (27.08 +/- 8.5 vs. 53.34 +/- 9.3 micromol.kg(FFM)(-1).min(-1); P < 0.001) becoming similar to the values currently reported for normal-weight subjects. In conclusion, in formerly severely obese subjects, weight loss paired with the reversibility of insulin resistance restores homeostatic control of the adiponectin secretion, contributing to the reduction of cardiovascular risk already described in these patients.

Abstract
A respiratory chamber is used for monitoring O2 consumption (V̇o2), CO2 production (V̇co2), and respiratory quotient (RQ) in humans, enabling long term (24-h) observation under free-living conditions. Computation of V̇o2 and V̇co2 is currently done by inversion of a mass balance equation, with no consideration of measurement errors and other uncertainties. To improve the accuracy of the results, a new mathematical model is suggested in the present study explicitly accounting for the presence of such uncertainties and error sources and enabling the use of optimal filtering methods. Experiments have been realized, injecting known gas quantities and estimating them using the proposed mathematical model and the Kalman-Bucy (KB) estimation method. The estimates obtained reproduce the known production rates much better than standard methods; in particular, the mean error when fitting the known production rates is 15.6 ± 0.9 vs. 186 ± 36 ml/min obtained using a conventional method. Experiments with 11 humans were carried out as well, where V̇o2 and V̇co2 were estimated. The variance of the estimation errors, produced by the KB method, appears relatively small and rapidly convergent. Spectral analysis is performed to assess the residual noise content in the estimates, revealing large improvement: 2.9 ± 0.8 vs. 3,440 ± 824 (ml/min)2 and 1.8 ± 0.5 vs. 2,057 ± 532 (ml/min)2, respectively, for V̇o2 and V̇co2 estimates. Consequently, the accuracy of the computed RQ is also highly improved (0.3 × 10-4 vs. 800 × 10-4). The presented study demonstrates the validity of the proposed model and the improvement in the results when using a KB estimation method to resolve it.

Abstract
The malnutrition caused by liver cirrhosis (LC) often worsens the course of the disease. Patients affected by LC often have a low bioavailability of the anabolic liver peptide insulin-like growth factor (IGF)-I. The present study was undertaken to investigate the effect of low doses of IGF-I on the nutritional status and in vivo jejunal transport of D-galactose in anatomically, pathologically and biochemically confirmed moderate, non-ascitic, cirrhotic rats. LC was experimentally induced in growing rats by inhalation of CCl4 and addition of phenobarbital to drinking water. Both the nutritional status, as evaluated by N balance, and in vivo intestinal transport of D-galactose, were significantly impaired in cirrhotic rats. As compared with healthy rats, administration of 20 microg human recombinant IGF-I/kg body weight for 14 d to cirrhotic rats significantly improved N balance variables and restored in vivo intestinal transport of the sugar. However, IGF-I had no effect on the steatorrhoea associated with LC. These results suggest that low doses of IGF-I may have beneficial effects on the malnutrition associated with moderate LC.

Abstract
BACKGROUND AND AIMS Little information are available on the relationship between energy balance and the alterations in nutritional status occurring in cirrhotic patients. The aim of the present study was to evaluate the daily energy balance in clinically stable cirrhotic patients with or without malnutrition. PATIENTS Seventy-four consecutive cirrhotic patients and nine healthy controls were studied. METHODS Basal energy expenditure was measured by indirect calorimetry and adjusted according to the patients' physical activity to estimate the daily energy expenditure. Food intake was evaluated based on a 3-day dietary diary. Nutritional status and body composition were assessed using skinfold anthropometry and dual energy X-ray absorptiometry, respectively. RESULTS Thirty-two patients in the cirrhotic group were classified as severely malnourished according to anthropometric parameters. Two different patterns of soft-tissue loss were observed in the malnourished cirrhotic group: a significant reduction in fat mass and in fat-free mass was observed in males, whereas, females showed a significant reduction in fat mass only. Basal energy expenditure was similar in all groups, while the non-protein respiratory quotient was lower in cirrhotics notwithstanding their nutritional status. This suggests that lipids were the preferred oxidized fuel in the post-absorptive state in these patients. No difference in the estimated daily energy expenditure and energy intake was observed among groups. Lipid content of the diet was significantly lower in malnourished cirrhotics than in controls (33.1+/-1% vs 37.8+/-1%, P=0.02). CONCLUSIONS Cirrhotic patients in stable clinical condition with malnutrition show a normal energy balance.

Abstract
The aim of this study was to investigate the sterol regulatory element-binding protein 1c (SREBP1c) mRNA muscle expression in morbid obese subjects before and after massive lipid malabsorption due to bariatric surgery (bilio-pancreatic diversion, BPD). We studied 11 obese subjects (BMI 49+/-2 kg/m2) before and 24 months after BPD. Skeletal muscle SREBP1c mRNA expression was determined using RT-competitive PCR. Intramyocytic triglycerides were quantified by HPLC. Insulin sensitivity (M/I) was assessed by euglycemic-hyperinsulinemic clamp. Energy expenditure and respiratory quotient (RQ) were measured over 24 h in a calorimetric chamber. Total cardiovascular risk dropped from 2 before to -2.5 after BPD (P<0.0001). The M/I value was normalized after surgery (0.036+/-0.0148 to 0.095+/-0.0147 micromol kgFFM(-1) min(-1) pmoles(-1) P<0.001). SREBP-1c mRNA levels were decreased (from 4.12+/-2.43 to 2.69+/-1.83% of cyclophilin mRNA, P=0.02) after BPD. In a multiple regression analysis, M/I values (P<0.0001) as well as the intramyocytic triglyceride levels (P=0.039) were the most powerful independent variables for predicting cardiovascular risk. Our results show that the reduction of cardiovascular risk after bariatric massive weight loss is strongly related to the reversion of insulin resistance and to the lowering of intramyocytic triglyceride depots. These two parameters are associated with a significant reduction in SREBP-1c mRNA expression in skeletal muscle, suggesting that this transcription factor might be involved in the accumulation of triglycerides in muscle cells of morbidly obese subjects.

Abstract
OBJECTIVE To examine the muscular uncoupling protein expression 2 (UCP2) and UCP3 gene expression in morbid obese subjects before and after bariatric surgery [bilio-pancreatic diversion (BPD)]. RESEARCH METHODS AND PROCEDURES Eleven obese subjects (BMI = 49 +/- 2 kg/m(2)) were studied before BPD and 24 months after BPD. Skeletal muscle UCP2 and UCP3 mRNA was measured using reverse transcriptase-competitive polymerase chain reaction and UCP3 protein by Western blotting. Intramyocytic triglycerides were quantified by high-performance liquid chromatography. Twenty-four-hour energy expenditure and respiratory quotient (RQ) were measured in a respiratory chamber. RESULTS After BPD, the average weight loss was approximately 38%. Nonprotein RQ was increased in the postobese subjects (0.73 +/- 0.00 vs. 0.83 +/- 0.02, p < 0.001). The intramyocytic triglyceride level dropped (3.66 +/- 0.16 to 1.60 +/- 0.29 mg/100 mg of fresh tissue, p < 0.0001) after BPD. Expression of UCP2 and UCP3 mRNA was significantly reduced (from 35.9 +/- 6.1% to 18.6 +/- 4.5% of cyclophilin, p = 0.02; from 60.2 +/- 14.0% to 33.4 +/- 8.5%, p = 0.03; respectively). UCP3 protein content was also significantly reduced (272.19 +/- 84.13 vs. 175.78 +/- 60.31, AU, p = 0.04). A multiple regression analysis (R(2) = 0.90) showed that IMTG levels (p = 0.007) represented the most powerful independent variable for predicting UCP3 variation. DISCUSSION The strong correlation of UCP expression and decrease in IMTG levels suggests that triglyceride content plays an even more important role in the regulation of UCP gene expression than the circulating levels of free fatty acids or the achieved degree of weight loss.

Abstract
Significant impairments of several aspects of immunity have been described in acute and chronic nutritional deficiencies; however, there have been few studies on antigen-presenting cells during starvation. We examined the antigen-presenting capacities of mouse dendritic cells (DCs) from lymphoid organ (spleen DCs) and non-lymphoid tissue (liver DCs) during starvation. The total numbers of spleen DCs and liver DCs were significantly fewer in starved mice than in control mice. Functional analysis showed that the proliferative activities of spleen DCs and liver DCs were significantly impaired in starved mice compared with control mice. In particular, liver DCs from starved mice were unable to induce interferon-gamma. Liver DCs from starved mice were unable to induce proliferation of antigen-specific memory lymphocytes. These data indicated that one major cause of impairment of immunologic responses during starvation may be mediated through DCs.

Abstract
The possibility of computing Diet Induced Thermogenesis (DIT) is an important feature of metabolic investigations. However, methodological problems have affected the determination of DIT in the indirect calorimetric chamber. DIT has been commonly estimated by regressing energy expenditure on a measure of physical activity. Although used for many years as the only feasible approach to calculate DIT in a respiratory chamber, this traditional method has been criticized because of an apparent underestimation of the DIT, but no alternative method has been suggested so far. The present work proposes to estimate DIT directly by means of a mathematical model. This approach also allows to simultaneously estimate other parameters, namely resting energy expenditure (REE), physical activity (PA) and physical exercise (PE).

Abstract
Liver has a central role in nutritional homeostasis and any liver disease leads to abnormalities in nutrient metabolism and subsequent malnutrition. All children with chronic liver disease (CLD) must undergo a periodic nutritional assessment--medical history, anthropometry esp. skinfold thickness and mid-arm circumference, and biochemical estimation of body nutrients. Nutritional rehabilitation is catered to the individual child but generally the caloric intake is increased to 130% of RDA by adding glucose polymers and/or MCT oil (coconut oil) with essential fatty acid supplementation (sunflower oil). The enteral route is preferred and occasionally nasogastric and/or nocturnal feeding are required to ensure an adequate intake. Proteins rich in branched chain amino acids are given in moderation (2-3 gm/kg/day) in compensated cirrhotics unless encephalopathy occurs when protein restriction may be necessary (1 gm/kg/day). Fat-soluble vitamins are supplemented in large quantities esp. in cholestasis along with other vitamins and minerals. Dietary therapy is the mainstay of management of some metabolic liver diseases and may be curative in disorders like galactosemia, fructosemia and glycogen storage disorders. Pre and postoperative nutritional support is an important factor in improving survival after liver transplantation.

Abstract
In the past year, some relevant papers related to the diagnosis of malnutrition and its pathogenesis in cirrhosis have been published. The value of anthropometrics in the nutritional assessment of end-stage cirrhotic patients has been reinforced. Also, the role of bioelectrical impedance analysis in these patients has been redefined. Several papers have investigated the relationship between leptin and malnutrition in chronic liver disease, particularly the role of alcoholism in hyperleptinaemia, and the importance of protein-bound leptin in these patients. In other papers, the impact of both undernutrition and obesity on the outcome of liver transplantation has been investigated. Two randomized, controlled trials on enteral nutrition in liver disease have been published in this period. One of them deals with a clinical situation (i.e. severe alcoholic hepatitis) associated with a high mortality rate, whereas the second is the first controlled trial in the field of preoperative nutrition in liver transplantation. Finally, some papers provide further arguments in the dilemma of which route of nutrition (enteral or parenteral) is better in cirrhosis.

Abstract
OBJECTIVE Malnutrition is common in patients with decompensated cirrhosis and refractory ascites. The use of transjugular intrahepatic portosystemic stent shunt (TIPS) is effective in eliminating ascites. The purpose of this study was to investigate the effect of TIPS and resolution of refractory ascites on the nutritional status of patients with decompensated cirrhosis. METHODS Fourteen consecutive patients with refractory ascites and a Pugh score of 9.0+/-0.5 had a TIPS insertion. Biochemical data, resting energy expenditure (REE), total body nitrogen (TBN), body potassium (TBK), body fat (TBF), muscle force (MF), and food intake were recorded before TIPS, and at 3 and 12 months after the procedure. RESULTS Ten patients completed the study. Baseline values for REE, TBN, TBF, MF, and energy intake were below normal at baseline. There was a significant increase in dry weight, TBN, and REE at 3 and 12 months compared with baseline. TBF improved significantly at 12 months. There was a trend toward an increase in energy intake (p = 0.072). There was no change in protein intake, TBK, MF, and Pugh score. CONCLUSION In cirrhotic patients with refractory ascites, resolution of the ascites after TIPS placement resulted in improvement of several nutritional parameters, especially for body composition.

Abstract
Protein-energy malnutrition (PEM) is a common problem in patients with end-stage liver disease, and it is universally present in patients undergoing orthotopic liver transplantation. Although PEM is an independent risk factor for morbidity and mortality, it need not be considered an absolute contraindication for liver transplantation. The etiology of PEM in liver disease is multifactorial and includes decreased nutrient and calorie intake, alterations in intestinal malabsorption and/or maldigestion, and diverse abnormalities of carbohydrate, fat, and protein metabolism. This article reviews the prevalence of malnutrition, its pathophysiology, different modalities for assessment of body composition, and general guidelines for nutritional support in patients with liver disease and liver transplantation.

Abstract
Diet treatment characterized by a reduction in or a selection of food proteins is currently suggested in hepatic encephalopathy. This article is a review of the present knowledge about the characteristics and the rationale of vegetarian diets in cirrhotic patients with overt or latent encephalopathy. In addition, evidence relating diet and encephalopathy and the nutritional features and needs of cirrhotic patients is reported. Finally, the rationale of a diet based on vegetable and milk-derived proteins that may overcome the limits and the possible adverse effects of a strict vegetarian diet is presented.
