Abstract
The present study provides insight into the differential response of a benzimidazole-malononitrile fluorescent "Turn-ON" probe on interaction with two structurally similar proteins, BSA and HSA. Compound 6 shows more sensitivity towards the two SAs, which is completely lost in the case of compound 7, synthesized by substitution on 6. The aggregates of compound 6 show absorption maxima at 385 nm and weak emission maxima at 565 nm. Compound 6 forms a new emission band at 475 nm on gradual addition of BSA (200 μM) along with a slight increase in the emission band at 565 nm. However, on addition of HSA (50 μM), a new band at 475 nm is formed. In contrast to BSA, in the case of HSA, 50% quenching is observed in the emission band of compound 6 at 565 nm. The new band formed on the interaction of 6 with BSA shows four-fold more enhancement compared to HSA. Furthermore, the mechanism of interaction of 6 with serum albumin has been investigated through lifetime-fluorescence analysis, site-selective drug experiments, dynamic light scattering, FE-SEM, FT-IR, etc. Molecular docking studies and site marker drug displacement experiments reveal differential interactions of 6 towards the two structurally similar proteins. Aggregates of 6 with an average hydrodynamic size of 100-190 nm are disassembled on adding BSA and HSA, and the size of the serum albumin and 6 complex decreases to 10-20 nm, revealing the ligand's encapsulation in the serum albumin cavity. Practical applicability for the quantitative detection of HSA in human urine samples is also demonstrated. The high binding affinity, sensitivity, selectivity and differential response of probe 6 towards two serum albumins (HSA and BSA) and significant quantification of HSA in urine samples shows the potential ability of this probe in medical applications.

Abstract
Transplantation of the liver in combination with other organs is an increasingly performed procedure. Over the years, continuous improvement in survival could be realized through careful patient selection and refined organ preservation techniques, in spite of the challenges posed by aging recipients and donors, as well as the increased use of steatotic liver grafts. Herein, we revisit the epidemiology, allocation policies in different transplant zones, indications, and outcomes with regard to simultaneous organ transplants involving the liver, that is combined heart-liver, liver-lung, liver-kidney, and multivisceral transplantation. We address challenges surrounding combined organ transplantation such as equity, utility, and logistics of dual organ implantation, but also advantages that come along with combined transplantation, thereby focusing on molecular mechanisms underlying immunoprotection provided by the liver to the other allografts. In addition, the current standing and knowledge of machine perfusion in combined organ transplantation, mostly based on center experience, will be reviewed. Notwithstanding all the technical advances, shortage of organs, and the lack of universal eligibility criteria for certain multi-organ combinations are hurdles that need to be tackled in the future.

Abstract
Liver cirrhosis is the 14th leading cause of death in adults worldwide. The liver is an important organ for the metabolism of sugar, protein, and fat. Liver cirrhosis with hypoproteinemia (LCH) can lead to metabolic disorders of the nutrients such as sugar, protein, and fat, as well as insufficient protein intake, digestion and absorption disorders, and continuous leakage of plasma protein into the abdominal cavity. Severe hypoproteinemia leads to a poor prognosis in patients. For every 10 g/L decrease in peripheral blood albumin, the risk of secondary liver disease complications will increase by 89% and the mortality rate increased by 24%–56%. Therefore, it is necessary to take urgent measures to treat liver cirrhosis with hypoalbuminemia and effectively treat and reverse the deterioration of the disease caused by hypoalbuminemia, so as to reduce the burden of secondary liver disease. Emerging evidence suggests that protein balance disorders, auxin resistance, and hyperleptinemia are key steps in the development of cirrhosis and hypoproteinemia. This study comprehensively analyzed the common complications, pathogenic mechanisms, and treatment status of cirrhosis caused by hypoproteinemia and proposed research prospects for dealing with this increasingly serious problem.

Abstract
Sarcopenia, frailty, and malnutrition are prevalent complications in patients with end-stage liver disease (ESLD) and are associated with increased risk of morbidity and mortality. It is valuable to measure nutritional status, sarcopenia, and frailty over time in order to create interventions tailored to individuals with ESLD. Evaluating sarcopenia and frailty in patients with ESLD is challenging. Further work is needed to perfect these assessments so that clinicians can incorporate these assessments into their decision-making and management plans for cirrhotic patients.

Abstract
Protein-energy malnourishment is commonly encountered in patients with end-stage liver disease who undergo liver transplantation. Malnutrition may further increase morbidity, mortality and costs in the post-transplantation setting. The importance of carefully assessing the nutritional status during the work-up of patients who are candidates for liver replacement is widely recognized. The metabolic abnormalities induced by liver failure render the conventional assessment of nutritional status to be challenging. Preoperative loss of skeletal muscle mass, namely, sarcopenia, has a significant detrimental impact on post-transplant outcomes. It is essential to provide sufficient nutritional support during all phases of liver transplantation. Oral nutrition is preferred, but tube enteral nutrition may be required to provide the needed energy intake. Herein, the latest currently employed perioperative nutritional interventions in liver transplant recipients are thoroughly illustrated including synbiotics, micronutrients, branched-chain amino acid supplementation, immunonutrition formulas, fluid and electrolyte balance, the offering of nocturnal meals, dietary counselling, exercise and rehabilitation.

Abstract
With the evolution of surgical and anesthetic techniques, liver transplantation has become "routine," allowing for modifications of practice to decrease perioperative complications and costs. There is debate over the necessity for intensive care unit admission for patients with satisfactory preoperative status and a smooth intraoperative course. Postoperative care is made easier when the liver graft performs optimally. Assessment of graft function, vigilance for complications after the major surgical insult, and optimization of multiple systems affected by liver disease are essential aspects of postoperative care. The intensivist plays a vital role in an integrated multidisciplinary transplant team.

Abstract
Nutrition therapy after small bowel or combined liver/small bowel transplantation is challenging. The objective is to restore enteral autonomy to a patient with a complex past surgical history and equally complex posttransplant immunosuppressive regimen in the context of a newly created surgical anatomy. Improved surgical techniques and immunosuppressive regimens have led to superior outcomes. Accompanying these advances is a range of nutrition issues that require specific management strategies. This review outlines the current clinical practice and decision making used to create individualized nutrition regimens for small bowel or combined liver/small bowel transplant recipients. Successful small bowel transplant outcomes require a coordinated effort from a transplant team to restore nutritional autonomy to transplant recipients and free them from parenteral nutrition.

Abstract
Protein-calorie malnutrition is a transversal condition to all stages of chronic liver disease. Early recognition of micro or macronutrient deficiencies is essential, because the use of nutritional supplements reduces the risk of complications. The diet of patients with chronic liver disease is based on a standard diet with supplements addition as necessary. Restrictions may be harmful and should be individualized. Treatment management should aim to maintain an adequate protein and caloric intake and to correct nutrient deficiencies. The large majority of patients with grade I/II hepatic encephalopathy can tolerate a regular diet. Protein restriction can aggravate malnutrition and is not recommended, except in cases of hepatic encephalopathy unresponsive to optimized therapy.

Abstract
BACKGROUND Spontaneous bacterial peritonitis (SBP) is a severe and often fatal infection in patients with cirrhosis and ascites. AIM To review the known and changing bacteriology, risk factors, ascitic fluid interpretation, steps in performing paracentesis, treatment, prophylaxis and evolving perspectives related to SBP. METHODS Information was obtained from reviewing medical literature accessible on PubMed Central. The search term 'spontaneous bacterial peritonitis' was cross-referenced with 'bacteria', 'risk factors', 'ascites', 'paracentesis', 'ascitic fluid analysis', 'diagnosis', 'treatment', 'antibiotics', 'prophylaxis', 'liver transplantation' and 'nutrition'. RESULTS Gram-positive cocci (GPC) such as Staphylococcus, Enterococcus as well as multi-resistant bacteria have become common pathogens and have changed the conventional approach to treatment of SBP. Health care-associated and nosocomial SBP infections should prompt greater vigilance and consideration for alternative antibiotic coverage. Acid suppressive and beta-adrenergic antagonist therapies are strongly associated with SBP in at-risk individuals. CONCLUSIONS Third-generation, broad-spectrum cephalosporins remain a good initial choice for SBP treatment. Levofloxacin is an acceptable alternative for patients not receiving long-term flouroquinolone prophylaxis or for those with a penicillin allergy. For uncomplicated SBP, early oral switch therapy is reasonable. Alternative antibiotics such as pipercillin-tazobactam should be considered for patients with nosocomial SBP or for patients who fail to improve on traditional antibiotic regimens. Selective albumin supplementation remains an important adjunct in SBP treatment. Withholding acid suppressive medication deserves strong consideration, and discontinuing beta-adrenergic antagonist therapy in patients with end-stage liver disease and resistant ascites is standard care. Liver transplant evaluation should be undertaken for patients who develop SBP barring contraindications.

Abstract
Liver transplantation (LT) is a major surgery performed on patients with end stage liver disease. Nutrition is an integral part of patient care, and protein-energy malnutrition is almost universally present in patients suffering from liver disease undergoing LT. Nutrition assessment of preliver transplant phase helps to make a good nutrition care plan for the patients. Nutrition status has been associated with various factors which are related to the success of liver transplant such as morbidity, mortality, and length of hospital stay. To assess the nutritional status of preliver transplant patients, combinations of nutrition assessment methods should be used like subjective global assessment, Anthropometry mid arm-muscle circumference, Bioelectrical impedance analysis (BIA) and handgrip strength.

Abstract
Protein-energy malnutrition is frequently seen in patients with end-stage liver disease who undergo liver transplantation. This causes a deterioration of the patients' clinical condition and affects their post-transplantation survival. Accurate assessment of the nutritional status and adequate intervention are prerequisites for perioperative nutritional treatment. However, the metabolic abnormalities induced by liver failure make the traditional assessment of the nutritional status difficult. The methods that were recently developed for accurately assessing the nutritional status by body bioelectrical impedance may be implemented in pre-transplant management. Because preoperative malnutrition and the loss of skeletal muscle mass, called sarcopenia, have a significant negative impact on the post-transplantation outcome, it is essential to provide adequate nutritional support during all phases of liver transplantation. Oral nutrition is preferred, but tube enteral nutrition may be required to provide the necessary caloric intake. We herein discuss both bioelectrical impedance and the latest findings in the current perioperative nutritional interventions in liver transplant patients regarding synbiotics, micronutrients, branched-chain amino acid supplementation, the use of immune system modulating formulas, the fluid balance and the offering of nocturnal meals.

Abstract
Administration of branched-chain amino acids (BCAA) has been reported to improve liver function, quality of life (QOL). However, in some malnourished patients, serum albumin levels do not improve in response to BCAA granules. In this study, we examined the effects of BCAA-enriched enteral nutrition in patients unresponsive to BCAA granules. Thirty-two decompensated cirrhotic patients at Osaka Medical College were enrolled in this study. Since all patients showed no improvement in serum albumin levels despite 3 months of BCAA granule administration, they were administered 50 g of a flavored BCAA-enriched enteral nutrient twice daily, i.e., during the daytime and late evening. Serum albumin levels and major cirrhotic symptoms were examined 1, 3, and 5 months after treatment initiation. Serum albumin levels improved significantly 3 months after treatment initiation (3.14 ± 0.32 g/dl vs 3.5 ± 0.31 g/dl, p<0.01), and Child–Pugh scores decreased significantly (p<0.01). In the majority (53–80%) of patients, muscles cramps, fatigue, fatigability, edema, and sleep disturbance improved within 3 months after therapy initiation. Moreover, approximately 90% of the patients became symptom-free 5 months after treatment initiation. These results indicate that switching to BCAA-enriched nutrients improves QOL of cirrhotic patients unresponsive to BCAA granules.

Abstract
Given the liver's multiple synthetic, regulatory and detoxifying functions, one of the characteristics accompanying severe hepatocellular dysfunction is the presence of malnutrition. This disorder is highly frequent in liver cirrhosis, even in the relatively early stages of the disease. Independently of the cause of the cirrhosis, poor nutritional status is associated with a worse prognosis and therefore early intervention to correct nutrient deficiency can prolong life expectancy, improve quality of life, reduce complications and increase the probability of successful transplantation. The present article reviews current knowledge of the diagnosis and management of malnutrition in patients with cirrhosis. Special attention is paid to the concept of the late evening snack and its characteristics, composition and probable benefits in the course of the disease.

Abstract
INTRODUÇÃO: A doença hepática crônica resulta em grande impacto funcional, causando perda de massa e função muscular com consequente redução da capacidade funcional. OBJETIVO: Avaliar e comparar a força muscular respiratória e a capacidade funcional dos candidatos ao transplante hepático que possuem classe B ou C segundo o Child-Pugh Score e correlacionar estas variáveis dentro de cada grupo. MÉTODOS: Estudo transversal, com amostra de conveniência composta por 35 pacientes, divididos em dois grupos a partir da pontuação obtida no Child-Pugh Score, sendo B (19 pacientes) e C (16 pacientes). Todos os indivíduos foram avaliados em um único momento, sendo mensuradas as pressões inspiratória máxima (PImáx) e expiratória máxima (PEmáx) e a distância percorrida no teste de caminhada de seis minutos (TC6M). RESULTADOS: Os indivíduos classificados com Child-Pugh Score B apresentaram maiores valores na PImáx (-86,05 ± 23,89 vs. -57,94 ± 14,14), p = 0,001, na PEmáx (84,16 ± 28,26 vs. 72,00 ± 16,94), p = 0,142, e na distância percorrida no TC6M (473,63 ± 55,276 vs. 376,13 ± 39,00), p = 0,001. Encontramos, ainda, correlação positiva entre os valores da PImáx e a distância percorrida no TC6M dentro grupo Child-Pugh Score B, r = 0,64 e p = 0,003. CONCLUSÃO: O progresso da doença hepática contribui para o surgimento de diversas complicações que, em conjunto, parecem contribuir para a redução da capacidade funcional dos indivíduos. Em nosso trabalho, isso ficou evidenciado pelo pior desempenho do grupo Child-Pugh Score C. Isto pode sugerir que a espera para o transplante hepático (TxH) pode agravar a capacidade funcional e a força muscular respiratória desses indivíduos.

Abstract
Patients with advanced liver disease have several risk factors to develop nutritional deficiencies. Accurate nutritional assessment is a real challenge because many of the traditionally measured parameters of nutritional status vary with severity of liver disease independently of nutritional status. The objective of this study was to compare different tools used to assess the nutritional status of patients waiting for a liver transplant. Patients were nutritionally assessed by SGA, anthropometry, handgrip dynamometry and biochemical tests. Clinical variables were cross analyzed with the nutritional assessment methods. There were 159 patients followed. Malnutrition ranged from 6.3% to 80.8% according to the different methods used. Agreement among all the methods was low (K < 0.26). Malnutrition prevalence according to different nutritional assessment tools did not differ among this group of patients in relation to the etiology of liver disease (p > 0.05) but increased with the more advanced stages of disease according to the Child-Pugh score. Only SGA showed significant relationships with clinical variables (Child-Pugh scores, p < 0.05; presence of ascites and/or edema, p < 0.01; and encephalopathy, p < 0.01). The various methods used showed great variability of results, lack agreement among them, and only SGA showed correlation with the progression of liver disease.

Abstract
Hepatic encephalopathy (HE) is an incompletely understood phenomenon and serves as a poor prognosis in patients with cirrhosis. Confusion from HE can affect the ability to eat adequately. Despite the prevalence of malnutrition in cirrhotic patients in the 1950s, it was reported that bouts of overt HE were controlled with low protein intake. This largely uncontrolled observation led to restriction of protein intake in cirrhotic patients with or without HE and was an accepted standard of care for many decades to follow. Published in 2004, the pivotal article "Normal Protein Diet for Episodic Hepatic Encephalopathy: Results of a Randomized Study" by Cordoba and colleagues was the first controlled study randomizing cirrhotic patients with HE to receive different amounts of dietary protein. At the completion of the study, the authors concluded that a normal-protein diet was safe and did not exacerbate HE. The Cordoba study suggests that low-protein diets should be abandoned. In light of this evidence, nutrition guidelines have proposed that protein restriction should be avoided in patients with HE as protein requirements are increased in cirrhosis. Despite the advice of experts in the field, it has been shown in recent years that some physicians still believe that protein restriction is needed in patients with HE. This belief has not been substantiated in controlled studies, and societal recommendations have changed. There is no real evidence documenting the advantages of protein restriction in HE. On the contrary, Cordoba and colleagues' article has shown that there are disadvantages to restricting protein in HE.

Abstract
Alcohol is a risk factor for chronic disease burden in developed countries. Alcoholic liver disease affects 1% of the North American population and is the second most frequent indication for liver transplantation in the United States. It is a spectrum that ranges from simple hepatic steatosis to alcoholic hepatitis to steatohepatitis and eventually cirrhosis. The clinical spectrum of alcoholic hepatitis is wide and ranges from the asymptomatic patient to overt liver failure and death. Liver biopsy as a means of prognostication in alcoholic hepatitis has mostly been replaced with less invasive scoring systems. The management of alcoholic liver disease is challenging. Abstinence is the cornerstone of therapy and should include rehabilitation with a multidisciplinary approach. No specific treatment is required in mild to moderate alcoholic hepatitis. In patients with severe hepatitis, there appears to be a moderate survival benefit from the use of either corticosteroids or pentoxifylline in the absence of contraindications to their use. Nonresponders should have steroid therapy withdrawn by day 7, as persistence with therapy is not beneficial. Orthotopic liver transplantation remains the definitive therapy for decompensated alcoholic cirrhosis despite alcohol abstinence. More studies are needed to define the optimal timing of orthotopic liver transplantation and patients at risk of alcohol relapse post-transplant. Mt Sinai J Med 76:484-498, 2009.

Abstract
Protein calorie malnutrition (PCM) is a well-known complication of chronic liver disease (CLD). A major contribution to PCM in CLD is restriction of dietary protein intake. After many decades of injudicious reduction in dietary protein, cirrhotic patients are now prescribed appropriate amounts of protein. PCM in CLD is known to be associated with life-threatening complications. In the general approach to these patients, the initial and most important step for the clinician is to recognize the extent of malnutrition. Most patients tolerate a normal amount of dietary protein without developing hepatic encephalopathy (HE). Oral branched-chain amino acids (BCAAs) have a limited role in HE. Patients who exhibit dietary protein intolerance originally were thought to be best treated with BCAA formulations. Mixed evidence has been reported in multiple studies. In keeping with other reports, this article shows that in animal protein-intolerant patients, even those with advanced cirrhosis, vegetable protein-based diets are well tolerated. Another approach to management of apparent dietary intolerance is to optimize HE treatment with available medications. This article reviews the causes of HE, minimal HE, and PCM; examines nutrition requirements and assessment; and discusses treatment options for malnutrition in HE.

Abstract
Foram avaliados dois protocolos de administração, em ratos sadios, de uma solução de fatores hepatotróficos (FH), composta por aminoácidos, vitaminas, sais minerais, glicose, insulina, glucagon e triiodotironina (T3). A solução foi administrada durante 10 dias, 40mg/kg/dia, i.p., em duas, grupo 2xFH (n=15), ou três doses, grupo 3xFH (n=15), diárias. Foram observados os efeitos na proliferação celular dos hepatócitos, na angiogênese e na matriz extracelular hepática, assim como as possíveis reações adversas. Os animais dos grupos 2xFH e 3xFH apresentaram aumento da massa hepática de 30,1% e 22,5%, respectivamente, em relação ao grupo-controle (CT; n=15). O índice de proliferação hepatocelular foi maior nos grupos 2xFH (1,4%) e 3xFH (1,2%) em relação ao grupo CT (0,53%), e a densitometria relativa do fator de crescimento do endotélio vascular pelo imunoblot não revelou diferença estatística entre os três grupos. Nos grupos 2xFH e 3xFH, houve redução do colágeno intersticial em relação ao grupo CT. A solução de FH estimulou o crescimento hepático e reduziu o volume de colágeno perissinusoidal. A administração em três doses diárias resultou em mortalidade de 26,7%, possivelmente pelo excessivo estresse da manipulação e pela menor adaptação fisiológica dos ratos, o que não ocorreu nos grupos 2xFH e CT. Para esse tipo de abordagem em ratos, o procedimento experimental mais apropriado, seguro, com melhor chance de adaptação dos animais e com resultados significativos é a aplicação dos FH em duas doses diárias.

Abstract
These recommendations provide a data-supported approach. They are based on the following: (i) a formal review and analysis of the recently published world literature on the topic (Medline search); (ii) American College of Physicians Manual for Assessing Health Practices and Designing Practice Guidelines (1); (iii) guideline policies, including the American Association for the Study of Liver Diseases (AASLD) Policy on the development and use of practice guidelines and the AGA Policy Statement on Guidelines (2); and (iv) the experience of the authors in the specified topic. Intended for use by physicians, these recommendations suggest preferred approaches to the diagnostic, therapeutic, and preventive aspects of care. They are intended to be flexible, in contrast to the standards of care, which are inflexible policies to be followed in every case. Specific recommendations are based on relevant published information. To more fully characterize the quality of evidence supporting the recommendations, the Practice Guideline Committee of the AASLD requires a Class (reflecting the benefit vs. risk) and Level (assessing the strength or certainty) of Evidence to be assigned and reported with each recommendation (Table 1, adapted from the American College of Cardiology and the American Heart Association Practice Guidelines) (3,4).

Abstract
The liver plays a central role in the regulation of nutrition by trafficking the metabolism of nutrients, their distribution and appropriate use. Accordingly, protein-energy malnutrition is common in patients with advanced liver disease, and it is a significant prognostic factor, affecting survival, the success of liver transplantation and quality of life. Clinical guidelines for the assessment and treatment of malnutrition have been issued by International societies, suggesting that nutritional therapy should be instituted in all patients where requirements are not adequately met by diet. The supplementation of the diet with amino acids (mainly branched-chain amino acids) and trace elements may improve nutritional status, liver function and hepatic encephalopathy. Nutritional issues should be carefully considered in Liver Units treating patients with advanced cirrhosis, and long-term, carefully controlled studies are needed to better define the type of nutritional support and the amount and timing of administration.

Abstract
BACKGROUND [corrected] Protein-calorie malnutrition is a frequent finding in patients with chronic liver disease, but investigations of nutritional status have been rarely performed in individuals seen at outpatient clinics AIM To evaluate the nutritional status of patients with alcoholic and nonalcoholic cirrhosis, attended for the first time at a reference outpatient clinic for liver diseases. PATIENTS AND METHODS A total of 300 consecutive patients attended at the outpatient clinics of a reference center for liver diseases were investigated. Anthropometric evaluation was performed by the usual parameters: triceps skinfold, arm circumference and arm muscle circumference. Biochemical parameters included creatinine/height index, serum albumin and lymphocytes count. The nutritional diagnosis was based on the PCM score proposed by Mendenhall et al. Food intake was retrospectively evaluated using 24-hour dietary recall data. RESULTS About 71% of the patients studied were chronic alcohol abusers, whereas in 29% cirrhosis was of nonalcoholic etiology. Independently of the disease etiology 75.3% of the patients showed some degree of protein-calorie malnutrition, which was moderate or severe in 38.3% of them. More advanced protein-calorie malnutrition degrees were associated with lower energy and protein intake. The prevalence of moderate or severe protein-calorie malnutrition was higher in patients classified as Child-Pugh C than in patients classified as Child-Pugh A (21% x 58%, respectively). Regarding sexual differences, fat reserves, evaluated by triceps skinfold, were more depleted in females than in males (48.6% x 26.6%) regardless of the etiology of the cirrhosis, whereas muscle reserves (arm muscle circumference) were more depleted in males (43.4% x 13.4%) regardless of the etiology of cirrhosis. In contrast, cirrhosis of alcoholic etiology was determinant in reducing arm muscle circumference in females (20% x 9.1%) CONCLUSIONS These data highlight the high prevalence of protein-calorie malnutrition occurring early in the natural history of the disease and accompanying functional hepatic deterioration. In addition, attention should be paid to the different gender patterns of response to protein-calorie malnutrition in these patients.

Abstract
The reported mortality rates in patients with cirrhosis undergoing various non-transplant surgical procedures range from 8.3% to 25%. This wide range of mortality rates is related to severity of liver disease, type of surgery, demographics of patient population, expertise of the surgical, anesthesia and intensive care unit team and finally, reporting bias. In this article, we will review the pathophysiology, morbidity and mortality associated with non-hepatic surgery in patients with cirrhosis, and then recommend an algorithm for risk assessment and evidence based management strategy to optimize post-surgical outcomes.

Abstract
PURPOSE OF REVIEW There is ample evidence that patients with liver disease have an ongoing energy and protein catabolism. Nutritional management in these patients must receive high priority. The administration of branched-chain amino acids to patients with liver disease has been a controversial subject. This review is an update on the data available from various studies involving branched-chain amino acids supplementation in patients with chronic liver disease and associated complications. RECENT FINDINGS This review summarizes the results of nutritional interventions involving branched-chain amino acids supplementation carried out in different centres around the world. It is interesting to note that no toxic effects of branched-chain amino acids supplementation have been reported in any of these trials. SUMMARY Administration of branched-chain amino acids stimulates hepatic protein synthesis in patients with chronic liver disease and this could contribute significantly to improving their nutritional status, and result in a better quality of life. The beneficial role of branched-chain amino acids supplementation in patients with chronic hepatic encephalopathy has been clearly documented in some studies but the exact mechanism of action is still not clear.

Abstract
BACKGROUND Resveratrol is a polyphenol with important antiinflammatory and antioxidant properties. We investigated the effect of resveratrol on alcohol-induced mortality and liver lesions in mice. METHODS Mice were randomly distributed into four groups (control, resveratrol-treated control, alcohol and resveratrol-treated alcohol). Chronic alcohol intoxication was induced by progressively administering alcohol in drinking water up to 40% v/v. The mice administered resveratrol received 10 mg/ml in drinking water. The animals had free access to standard diet. Blood levels were determined for transaminases, IL-1 and TNF-alpha. A histological evaluation was made of liver damage, and survival among the animals was recorded. RESULTS Transaminase concentration was significantly higher in the alcohol group than in the rest of the groups (p < 0.05). IL-1 levels were significantly reduced in the alcohol plus resveratrol group compared with the alcohol group (p < 0.05). TNF-alpha was not detected in any group. Histologically, the liver lesions were more severe in the alcohol group, though no significant differences between groups were observed. Mortality in the alcohol group was 78% in the seventh week, versus 22% in the alcohol plus resveratrol group (p < 0.001). All mice in the alcohol group died before the ninth week. CONCLUSION The results obtained suggest that resveratrol reduces mortality and liver damage in mice.

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
OBJECTIVE This study compared three methods of assessing malnutrition in cirrhotics and correlated nutritional status with clinical outcome. METHODS This cross-sectional study evaluated nutritional status by subjective global assessment (SGA), prognostic nutritional index (PNI), and handgrip strength (HG) in outpatients with cirrhosis (n = 50) and two control groups with hypertension (n = 46) and functional gastrointestinal disorders (n = 49). Patients with cirrhosis were followed for 1 y to verify the incidence of major complications, the need for transplantation, and death. RESULTS Among patients with cirrhosis, 88% were Child-Pugh A and only 12% were Child-Pugh B. Among these, prevalences of malnutrition were 28% by SGA, 18.7% by PNI, and 63% by HG (P < 0.05). HG, but not SGA or PNI, predicted a poorer clinical outcome in patients with cirrhosis because major complications such as uncontrolled ascites, hepatic encephalopathy, spontaneous bacterial peritonitis, and hepatorenal syndrome developed in 65.5% of malnourished patients versus 11.8% of well-nourished ones (P < 0.05). No significant differences by any method were seen between the two groups regarding liver transplantation or death. CONCLUSIONS There was a high prevalence of malnutrition in cirrhotic outpatients, especially when assessed by HG, which was superior to SGA and PNI in this study. HG was the only technique that predicted a significant incidence of major complications in 1 y in undernourished cirrhotic patients.

Abstract
BACKGROUND Malnutrition is common in patients with end-stage liver disease considered for transplantation, but it is unclear whether this affects the outcome after transplantation. AIM.: To determine whether the severity of malnutrition in liver transplant candidates affects outcome after transplantation. METHODS We did a prospective study of 61 patients with chronic liver disease accepted for transplantation. FINDINGS The Child-Pugh and Model for End-Stage Liver Disease (MELD) score correlated significantly but weakly with the mid-arm circumference (MAC) (rho=-0.34 and -0.31, P=0.015 and 0.025, respectively) but not with hand-grip strength, triceps skin-fold thickness (TSFT), or mid-arm muscle circumference. The Child-Pugh score but not the MELD was significantly associated with intensive therapy unit stay but not eventual outcome; there was a weak but statistically significant correlation between death and MAC (rho=+0.29, P=0.04) and TSFT (rho=+0.25, P=0.02). CONCLUSIONS These findings suggest that nutritional parameters and markers of disease severity do not correlate well with outcomes after transplantation.

Abstract
Cirrhosis and its sequelae are responsible for close to 2% of all causes of death in the United States. Some studies have suggested that the costs of liver disease may account for as much as 1% of all health care spending, with alcohol-related liver disease (ALD) representing a major portion. It accounts for between 40% to 50% of all deaths due to cirrhosis, with an accompanying rate of progression of up to 60% in patients with pure alcoholic fatty liver over 10 years, and a 5-year survival rate as low as 35% if patients continue to drink. A subset of patients with ALD will develop an acute, virulent form of injury, acute alcoholic hepatitis, which has a substantially worse prognosis. Despite enormous progress in understanding the physiology of this disease, much remains unknown, and therefore, a consensus regarding effective therapy for ALD is lacking. Conventional therapy is still based largely on abstinence from alcohol, as well as general supportive and symptomatic care. Unfortunately, hepatocellular damage may progress despite these measures. Multiple treatment interventions for both the short- and long-term morbidity and mortality of this disease have been proposed, but strong disagreement exists among experts regarding the value of any of the proposed specific therapeutic interventions.

Abstract
AIM: To investigate the safety, rationality and the practicality of enteral nutritional (EN) support in the postoperative patients with damaged liver function and the protective effect of EN on the gut barrier.
METHODS: 135 patients with liver function of Child B or C grade were randomly allocated to enteral nutrition group (EN, 65 cases), total parenteral nutrition group (TPN, 40 cases) and control group (CON, 30 cases). Nutritional parameters, hepatic and kidney function indexes were measured at the day before operation, 5th and 10th day after the operation respectively. Comparison was made to evaluate the efficacy of different nutritional support. Urinary concentrations of lactulose (L) and mannitol (M) were measured by pulsed electrochemical detection (HPLC-PED) and the L/M ratio calculated to evaluate their effectiveness on protection of gut barrier.
RESULTS: No significant damages in hepatic and kidney function were observed in both EN and TPN groups between pre- and postoperatively. EN group was the earliest one reaching the positive nitrogen balance after operation and with the lowest loss of body weight and there was no change in L/M ratio after the operation (0.026 ± 0.004) at the day 1 before operation, 0.030 ± 0.004 at the day 5 postoperative and 0.027 ± 0.005 at the day 10 postoperative), but the change in TPN group was significant at the day 5 postoperative (0.027 ± 0.003 vs 0.038 ± 0.009, P < 0.01).
CONCLUSION: EN is a rational and effective method in patients with hepatic dysfunction after operation and has significant protection effect on the gut barrier.

Abstract
Nutritional abnormalities almost uniformly accompany the metabolic disturbances of severe chronic liver disease and may adversely affect patient well-being and survival, especially surrounding liver transplantation surgery. The exact metabolic alterations responsible for malnutrition and its consequences in these patients have been debated and are a focus of this review. Disturbances in energy production and utilization, as well as macro- and micronutrient metabolism have been appreciated but are not always easily identified or quantifiable. Interestingly, the manifestations of poor nutritional status can vary substantially between patients, even in those having the same etiology and severity of illness. Proper assessment of patients with liver disease for malnutrition carries its own challenges, but some of the more easily applied techniques, such as anthropometry, can be comparable in accuracy to more sophisticated measuring tools. Gaining an appreciation and understanding of how nutritional disturbances develop and can contribute to morbidity and mortality will help combat inappropriate nutritional losses in this specialized group of patients. In many instances, simple adjustments in diet can offset losses and stabilize or improve the patient's nutritional status.

Abstract
Most adult and pediatric liver transplantation candidates present several metabolic disturbances that lead to malnutrition. Because malnutrition may adversely affect morbidity and mortality of orthotopic liver transplantation, it is very important to carefully assess the nutritional status of the waiting list patients. Pretransplant nutritional therapy -- enteral or parenteral -- may positively influence liver metabolism, muscle function, and immune status. Nutrition therapy should continue in the short- and also in the long-term post-transplant periods. For malnourished patients, early post-transplant enteral or parenteral nutrition have been useful in improving nutritional status. Finally, the metabolic and nutritional care of the liver transplant donor must be considered to reduce allograft dysfunction indices.

Abstract
Most instances of hepatotoxicity due to paracetamol in the United Kingdom and Australia are the result of large overdoses of the drug taken with suicidal or parasuicidal intent. In contrast, serious hepatotoxicity at recommended or near-recommended doses for therapeutic purposes has been reported, mainly from the United States and in association with chronic alcohol use, leading to the widely held belief that chronic alcoholics are predisposed to paracetamol-related toxicity at relatively low doses. Yet the effects of alcohol on paracetamol metabolism are complex. Studies performed in both experimental animals and humans indicate that chronic alcohol use leads to a short-term, two- to threefold increase in hepatic content of cytochrome P4502E1, the major isoform responsible for the generation of the toxic metabolite from paracetamol, although increased oxidative metabolism of paracetamol at recommended doses has not been demonstrated clinically. A reduced hepatic content of glutathione, required to detoxify the reactive metabolite, has been documented in chronic alcoholics, due probably to associated fasting and malnutrition, providing a metabolic basis for any possible predisposition of this group to hepatotoxicity at relatively low paracetamol doses. Simultaneous alcohol and paracetamol ingestion reduces oxidative metabolism of paracetamol in both rodents and humans, predominantly as a consequence of depletion in cytosol of free NADPH. The possibilities that chronic alcohol use may predispose to paracetamol-related hepatotoxicity and that alcohol taken with paracetamol may protect against it, based on these metabolic observations, are examined in this review.

Abstract
BACKGROUND Malnutrition, sometimes severe is common in patients with chronic hepatic diseases who are candidates for liver transplantation. Nutritional therapy can induce partial or total correction of such deficiencies, improving clinical conditions and prognosis of patients who face the great defiance of liver transplantation. AIMS Brief revision of hepatic role in the metabolism of several nutrients. Description of available methods of dietary therapy and its application both under different abnormal hepatic conditions and pre and post-transplant periods. The role of nutritional intervention in metabolic side effects due to immunosuppressive drugs. CONCLUSION Nutritional therapy is a valuable adjuvant resource to the clinical treatment of candidates and submitted patients to hepatic transplantation providing better prognosis and improved life quality.

Abstract
BACKGROUND Although branched-chain aminoacids (BCAA) are reported to be effective in prolongation of the mean survival time of patients with liver cirrhosis, it is not clear whether BCAA could influence the immune function in those patients. METHODS Branched-chain amino acids were given as a supplement to carbon tetrachloride-induced cirrhotic rats, and an aminogram of the liver and kinetics of liver-associated lymphocytes (LAL) were then analysed. RESULTS Liver cirrhosis was established at the 12th week, and glutathione S-transferase placental form (GST-P)-positive lesions, which are known to be pre-neoplastic lesions, occupied 1.72+/-0.84% of the liver at the 16th week in the controls. At this time the LAL showed an increase in the number of CD5-, CD8- and CD18-positive cells and augmentation of lectin-dependent cellular cytotoxicity (LDCC) activity. Furthermore, supplementation of BCAA increased the number of LAL, especially CD8-positive cells and natural killer cells, and augmented LDCC activity of LAL at the 16th week. The number of LAL was positively correlated with the valine concentration in the plasma and liver, and the area of GST-P-positive lesions tended to be decreased in the BCAA group. CONCLUSION These findings suggest that BCAA administration has stimulatory effects on the local immune systems of the liver, which may have a potential to inhibit hepatocarcinogenesis. Moreover, among all amino acids valine might be an important amino acid for enhancing the immune function of LAL.

Abstract
The underlying causative agent in the majority of patients with chronic liver disease is ethanol; the rest of the cases are largely viral in aetiology (hepatitis B or C viruses). Nutrition supplementation improves the quality of life and decreases morbidity in chronic liver disease, but evidence that it prolongs long-term survival is lacking. The situation is very different in chronic liver disease patients who receive a liver transplant, however, with better pretransplantation nutrition status predicting a distinctly improved survival after transplantation.

Abstract
Liver chronic pathologies often courses with metabolic abnormalities of macronutrients leading to or aggravating a protein-energy malnutrition status. This review raised the major pathophysiological mechanisms related to the protein-energy malnutrition in chronic liver patients. By large the reduced dietary intake is the most accepted cause particularly among alcoholic patients. Moreover during the treatment prevails the iatrogenic anorexia by unpalatable (restricted) diets interpolated with long-lasting fastings of hospitalized patients. Intestinal fat malabsorption is a common finding whereas hypermetabolism can be found associated with an acute alcoholism. Hypoglycemia or insulin resistance, hypertriglyceridemia and liver steatosis are common findings as well as lower plasma proteins along with higher levels of ammonia, aromatic and sulphur amino acids leading to neurological outcomes. The knowledge of these metabolic changes allow proper dietary interventions toward reduced morbi-mortality of those patients.

Abstract
BACKGROUND Malnutrition is usual in patients with alcoholic liver disease and is associated with a poor outcome. Nutritional support decreases nutrition-associated complications. AIM To demonstrate that nutritional support in ambulatory alcoholic cirrhotic patients improves host defenses. METHODS Thirty-one male outpatients with alcoholic cirrhosis CHILD-PUGH B or C were included. Twenty-five subjects completed six months consuming daily a nutritional supplement (Ensure, 1000 Kcal and 35 g protein), in addition to their regular diet. At entrance and every three months, a clinical assessment, nutritional evaluation and indirect calorimetry were performed. Liver function tests and LPS-induced monocyte production of cytokines, salivary secretory IgA, lactulose/mannitol ratio and breath hydrogen tests were also measured in these intervals. Delayed cutaneous hypersensitivity and IgG and IgM antibody response to endotoxin were assessed at entrance and at the end of the study. RESULTS Patients drank 85% of the provided supplement as an average. REE, total body fat and serum albumin increased, basal breath hydrogen decreased and cellular immunity improved significantly during the follow up period (p< or =0.03). All the other parameters remained unchanged throughout the study. Six patients (16.2%) died during the study, five due to upper gastrointestinal bleeding. CONCLUSION Nutritional support in alcoholic cirrhotic patients improves nutritional status and cell mediated immunity.
