Abstract
Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD) is a common cause of chronic liver disease globally, with prevalence rapidly increasing in parallel with rising rates of obesity and metabolic syndrome. MASLD is defined by the presence of excess fat in the liver, which may induce inflammatory changes and subsequent fibrosis in high-risk patients. Though MASLD occurs frequently, there is still no approved pharmacological treatment, and the mainstay of therapy remains lifestyle modification via dietary changes, enhancement of physical activity, and management of metabolic comorbidities. Most nutrition research and clinical guidance in this disease centers on the reduction in fructose and saturated fat in the diet, although the emerging literature suggests that protein supplementation is important and implicates muscle mass and sarcopenia in disease-related outcomes. This review will assess the current data on these topics, with the goal of defining best practices and identifying research gaps in care.

Abstract
We evaluated the safety and tolerability of AXA1665, a novel investigational fixed-ratio amino acid (AA) composition, the pharmacokinetics (PK) of the constituent AAs within AXA1665, and their relative bioavailability versus standard protein supplement. This study was conducted in 2 phases; in the initial phase, healthy subjects (N = 16) were randomly assigned to 4 treatment sequences (AXA1665 4.9, 9.8, and 19.6 g or 35 g protein supplement) in an open-label, single-dose, 4-way crossover study, while in the extension phase, they received single AXA1665 doses of 29.4 and 39.2 g in a sequential crossover manner. The net area under the plasma concentration-time curve (AUC) and observed time to reach maximum plasma concentration were estimated. A dose-dependent increase in plasma AUC from time 0 to the last measurable concentration (AUClast ) and maximum plasma concentration (Cmax ) was observed for all AXA1665-dosed AAs (4.9-39.2 g) except aspartic acid. AXA1665 19.6 g resulted in 1.5- to 9.5-fold higher systemic exposure to all AXA1665-dosed AAs except for aspartic acid and lysine and lower exposure to all nondosed AAs except for glutamine and alanine versus protein supplement. AXA1665 doses, up to 39.2 g, can deliver AXA1665-dosed AAs in the systemic circulation in the linear AUC range.

Abstract
Malnutrition is a common finding in alcohol use disorders and is associated with the prognosis of patients with alcoholic liver disease (ALD). These patients also frequently show deficiencies in vitamins and trace elements, increasing the likelihood of anemia and altered cognitive status. The etiology of malnutrition in ALD patients is multifactorial and complex and includes inadequate dietary intake, abnormal absorption and digestion, increased skeletal and visceral protein catabolism, and abnormal interactions between ethanol and lipid metabolism. Most nutritional measures derive from general chronic liver disease recommendations. Recently, many patients with ALD have been diagnosed with metabolic syndrome, which requires individualized treatment via nutritional therapy to avoid overnutrition. As ALD progresses to cirrhosis, it is frequently complicated by protein–energy malnutrition and sarcopenia. Nutritional therapy is also important in the management of ascites and hepatic encephalopathy as liver failure progresses. The purpose of the review is to summarize important nutritional therapies for the treatment of ALD.

Abstract
Hepatic encephalopathy (HE) is a serious complication of cirrhosis that causes neuropsychiatric problems, such as cognitive dysfunction and movement disorders. The link between the microbiota and the host plays a key role in the pathogenesis of HE. The link between the gut microbiome and disease can be positively utilized not only in the diagnosis area of HE but also in the treatment area. Probiotics and prebiotics aim to resolve gut dysbiosis and increase beneficial microbial taxa, while fecal microbiota transplantation aims to address gut dysbiosis through transplantation (FMT) of the gut microbiome from healthy donors. Antibiotics, such as rifaximin, aim to improve cognitive function and hyperammonemia by targeting harmful taxa. Current treatment regimens for HE have achieved some success in treatment by targeting the gut microbiota, however, are still accompanied by limitations and problems. A focused approach should be placed on the establishment of personalized trial designs and therapies for the improvement of future care. This narrative review identifies factors negatively influencing the gut–hepatic–brain axis leading to HE in cirrhosis and explores their relationship with the gut microbiome. We also focused on the evaluation of reported clinical studies on the management and improvement of HE patients with a particular focus on microbiome-targeted therapy.

Abstract
BACKGROUND Cirrhosis is a chronic and progressive liver disease that occurs from prolonged hepatocellular injury. Malnutrition causes complications in cirrhosis patients that worsen the condition to liver failure. Both are closely linked and increase the chances of morbidity and mortality. Regular nutritional screening and monitoring is prime concern for such patients including comprehensive dietary history, laboratory tests, and evaluation of muscle loss and strength capabilities to determine the degree of frailty. For efficient assessment of liver cirrhosis patients Subjective Global Assessment has been used worldwide. The nutritional objectives for such individuals should be to regain liver functions, to prevent complications associated, and to overcome nutritional deficiencies causing malnutrition. METHODS We conducted a literature review using PubMed, Google Scholar and Science Direct for this purpose, a total of 130 articles were reviewed out of which 80 (from the past 5 years) including originally published research, review articles and abstracts were also included. Exclusion criteria of the selected studies was year of publication, irrelevancy and animal studies based on the purpose of current study. The aim of this study was to check nutritional management in patients having complications of liver cirrhosis. RESULTS According to the guidelines, for the conservation of normal nutritional status of the malnourished patients', energy should be provided 35 kcal/kg/day while to prevent hypoalbuminemia and maintain the protein stores in the body, 1.5 g/kg/day protein has been recommended. Carbohydrates and fats for cirrhosis patients are recommended 50% to 60% and 10% to 20% of the total dietary intake respectively. CONCLUSION Initial identification and prevention of malnutrition have the probability to lead to better health outcomes, prevention of complications of the disease, and improving quality of life.

Abstract
INTRODUCTION AXA1665 is a novel investigational amino acid (AA) composition specifically designed to impact AA imbalance, ammoniagenesis, and dysregulated anabolic activity associated with cirrhosis. METHODS This 2-part study examined AXA1665 effects on safety, tolerability, and hepatic/muscle physiology in subjects with Child-Pugh A and B cirrhosis. Part 1 established plasma ammonia and AA concentration baselines with a standardized protein supplement. Part 2 included two 15-day domiciled periods separated by a 14-day washout. In period 1, subjects were randomly distributed to 2 groups: AXA1665 14.7 g t.i.d. (group 1) or control t.i.d. (group 2). In period 2, subjects from group 1 crossed over to control and those in group 2 crossed over to AXA1665 4.9 g t.i.d. All subjects were maintained on standard of care (standardized meals; 30-minute daily, supervised, mandatory physical activity; and daily late-evening snack). RESULTS In parts 1 and 2, 23 and 17 participants were enrolled, respectively. Dose-dependent increases were observed in plasma concentrations of AXA1665-constituent AAs. Fasted branched-chain AA-to-aromatic AA and valine-to-phenylalanine ratios were both increased (AXA1665 14.7 g t.i.d. control-adjusted change: 44.3% ± 2.7% and 47.2% ± 3.9%, respectively; P < 0.0001). Despite provision of additional nitrogen, mean fasted plasma ammonia concentration at day 15 numerically decreased (-21.1% in AXA1665 14.7 g t.i.d. vs -3.8% in control; P > 0.05). AXA1665 14.7 g t.i.d. produced a leaner body composition and significantly decreased Liver Frailty Index at day 15 vs control (-0.70 ± 0.15 vs -0.14 ± 0.17; P < 0.05). AXA1665 was safe and well tolerated. DISCUSSION AXA1665 has potential to mitigate core metabolic derangements associated with cirrhosis.

Abstract
BACKGROUND Previous studies of patients with liver cirrhosis have not considered the broad range of symptoms or the association between healthy behavior and quality of life. The purposes of this study were to examine the association between symptoms and adopting exercise and consuming fruits and vegetables and to identify factors associated with quality of life in patients with liver cirrhosis. METHODS This cross-sectional study enrolled 91 consecutive patients with liver cirrhosis in one tertiary general hospital in South Korea between February 2016 and January 2017. Each study participant completed a self-administered questionnaire that measured symptom, stage of change in engaging in exercise and consumption of fruits and vegetables, and the Korean version of the 36-item Short-Form Health Survey. Multivariate ordinal logistic regression analysis and multiple regression models was used, respectively, to examine the association between each symptom with stage of change in engaging in exercise and consumption of fruits and vegetables and to evaluate factors affecting quality of life. RESULTS Experiencing nausea was associated with more readiness for change in engaging in exercise, but experiencing shortness of breath was associated with less readiness for change in engaging in exercise. Experiencing right upper quadrant pain was associated with more readiness for change in engaging in consumption of fruits and vegetables. Muscle cramps, anorexia, right upper quadrant pain and body pain, itching, ascites or edema, bruising, and change in appearance negatively affected quality of life. CONCLUSIONS The results suggest that the types of symptoms experienced by a patient with liver cirrhosis hinder or promote the patient's adoption of exercise and dietary behavior. Experiencing symptoms may negatively affect quality of life. Caregivers should provide supportive care to patients with liver cirrhosis, which includes assessing and managing symptoms to improve quality of life.

Abstract
Malnutrition and sarcopenia have a high prevalence in cirrhotic patients. Frailty generally overlaps with malnutrition and 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 in cirrhosis is complex and multifactorial and it is not just due to reduction in protein and calorie intake. 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, these latter 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. Malnutrition, sarcopenia and frailty are unique, inter-related and multidimensional problems in cirrhosis which require special attention, prompt assessment and appropriate management as they significantly impact morbidity and mortality.

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
Hepatic encephalopathy (HE) is a common and serious neuropsychiatric complication of cirrhosis, acute liver failure, and porto-systemic shunting. HE largely contributes to the morbidity of patients with liver disease, severely affecting the quality of life of both patients and their relatives and being associated with poor prognosis. Its presentation is largely variable, manifesting with a broad spectrum of cognitive abnormalities ranging from subtle cognitive impairment to coma. The pathogenesis of HE is complex and has historically been linked with hyperammonemia. However, in the last years, it has become evident that the interplay of multiple actors, such as intestinal dysbiosis, gut hyperpermeability, and neuroinflammation, is of crucial importance in its genesis. Therefore, HE can be considered a result of a dysregulated gut-liver-brain axis function, where cognitive impairment can be reversed or prevented by the beneficial effects induced by “gut-centric” therapies, such as non-absorbable disaccharides, non-absorbable antibiotics, probiotics, prebiotics, and fecal microbiota transplantation. In this context dietary modifications, by modulating the intestinal milieu, can also provide significant benefit to cirrhotic patients with HE. This review will provide a comprehensive insight into the mechanisms responsible for gut-liver-brain axis dysregulation leading to HE in cirrhosis. Furthermore, it will explore the currently available therapies and the most promising future treatments for the management of patients with HE, with a special focus on the dietary approach.

Abstract
The aim of the study was to examine whether a rat model of liver cirrhosis induced by carbon tetrachloride (CCl4) is a suitable model of muscle wasting and alterations in amino acid metabolism in cirrhotic humans. Rats were treated by intragastric gavage of CCl4 or vehicle for 45 days. Blood plasma and different muscle types-tibialis anterior (mostly white fibres), soleus (red muscle) and extensor digitorum longus (white muscle) - were analysed at the end of the study. Characteristic biomarkers of impaired hepatic function were found in the plasma of cirrhotic animals. The weights and protein contents of all muscles of CCl4-treated animals were lower when compared with controls. Increased concentrations of glutamine (GLN) and aromatic amino acids (phenylalanine and tyrosine) and decreased concentrations of branched-chain amino acids (BCAA), glutamate (GLU), alanine and aspartate were found in plasma and muscles. In the soleus muscle, GLN increased more and GLU and BCAA decreased less than in the extensor digitorum and tibialis muscles. Increased chymotrypsin-like activity (indicating enhanced proteolysis) and decreased α-ketoglutarate and ATP levels were found in muscles of cirrhotic animals. ATP concentration also decreased in blood plasma. It is concluded that a rat model of CCl4-induced cirrhosis is a valid model for the investigation of hepatic cachexia that exhibits alterations in line with a theory of role of ammonia in pathogenesis of BCAA depletion, citric cycle and mitochondria dysfunction, and muscle wasting in cirrhotic subjects. The findings indicate more effective ammonia detoxification to GLN in red than in white muscles.

Abstract
AIM To evaluate the association between dietary protein sources with disease severity, malnutrition and anthropometric measurements in cirrhotic patients. BACKGROUND Although the beneficial effects of protein and some amino-acids have been shown previously, no study has evaluated the effects of different dietary sources of proteins in patients with hepatic cirrhosis. METHODS In this cross-sectional study, dietary intakes of patients with hepatic cirrhosis were assessed using a valid and reliable food frequency questionnaire. The association between different dietary sources of proteins and nutritional status, anthropometric measurements, and disease severity were evaluated. RESULTS Muscle strength (MS) increased significantly in highest tertile of dairy and vegetable protein sources compared with the lowest one (p=0.045). Dietary dairy and vegetable protein intakes had a positive significant correlation with body weight, MS, visceral fat percentage (VFP), and triceps skin-fold thickness (TST), and negative significant correlation with malnutrition stage. CONCLUSION Our results indicate that consumption of proteins from dairy and vegetable sources is associated with improvement in nutritional and anthropometric status of patients with hepatic cirrhosis. Further prospective studies are needed to confirm these results.

Abstract
Food plays an essential role in normal cellular processes; however, certain foods may also trigger or worsen certain disease states. This article focuses particularly on the role of food in common gastrointestinal and liver diseases, and discusses the current evidence that either supports or debunks common dietary recommendations. Nutrition topics discussed include the use of artificial sweetener for weight loss, avoidance of all dairy products in the setting of lactose intolerance, dietary recommendations for diverticular disease, and dietary management in cirrhotic patients with hepatic encephalopathy.

Abstract
Sarcopenia is an important burden in liver cirrhosis representing a negative prognostic factor for mortality. Moreover, sarcopenia is an independent predictor of complications in patients with liver cirrhosis, including Hepatic Encephalopathy (HE). An association between sarcopenia and HE in liver cirrhosis has been reported in recent studies, indeed both these complications often affect patients with advanced liver cirrhosis and may exert a synergic effect in deteriorating patients' outcome. Episodes of HE occur more often in patients with muscle depletion. The rationale for these finding is based on the role played by muscle in ammonia detoxification due to the inability of urea synthesis in the cirrhotic liver. Consequently, muscle depletion may have relevant implications in favoring hyperammonemia and HE. At the same time hyperammonemia has been found to impair muscle protein synthesis through myostatin down-regulation. From this point of view, modulation of diet and amelioration of nutritional status and muscle mass can be considered a potential goal to prevent this vicious circle and improve the cognitive impairment in cirrhotic patients.

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
Hyperammonemia plays a key role in the pathophysiology of hepatic encephalopathy (HE) and most HE treatments are ammonia-lowering drugs. However, the usefulness of measuring ammonemia in routine practice remains controversial and not recommended systematically even when neurological symptoms are present. First, ammonemia measurement should be carefully performed in order to avoid a falsely elevated result. When performed, a normal ammonemia in a cirrhotic patient with neurological symptoms should lead to reconsider the diagnosis of HE. Indeed, literature data show that most cirrhotic patients with HE have an elevated ammonemia, which is however individually poorly correlated with the severity of symptoms. Nevertheless, elevated ammonemia seems to be a factor of bad prognosis in cirrhosis. A decrease in ammonemia after treatments is well proven but it is not determined whether it is associated with clinical efficacy. Repeated measurements could be useful in this context, especially in non-responders, to help differentiating other causes of encephalopathy, such as drug induced. In acute liver failure, the prognostic value of hyperammonemia is well described and could help an early recognition the most severe forms of this disease. We will also discuss how integrating ammonemia into the diagnostic work-up of liver failure and/or encephalopathy. Ammonemia is also essential to diagnose urea cycle disorders or drug toxicity that both need specific interventions.

Abstract
Liver cirrhosis is associated with significant nutritional risks that often result in serious hepatic complications and poor survival rates. Diet is an important but underutilized aspect in the treatment modality of cirrhosis. Therefore, the aims of this review are to ascertain nutritional risks associated with its pathophysiology and to summarize existing evidence that support dietary recommendations for managing this patient population. Alterations in substrate utilization for energy production is a main feature of liver cirrhosis, resulting in increased catabolism of protein stores and a predisposition toward protein-energy malnutrition, even in the early stages of the disease. The body of evidence suggests that a high energy and protein (>1.2 g/kg body weight/d) diet consumed frequently and late in the evening is effective in improving nutritional status of these patients and has been associated with improved hospitalization and mortality rates. The use of branched-chain amino acid supplementation shows promise in reducing cirrhosis-related complications but are currently limited by adverse gastrointestinal symptoms and poor palatability. Furthermore exploration of dietary manipulation of branched-chain amino acid warrants further examination. Evidence is also accumulating that protein intake should not be restricted in patients with hepatic encephalopathy with earlier studies of protein restriction neglecting to account for the relative increase in fermentable fiber which would reduce the absorption of ammonia into the portal system in a way similar to supplementation with lactulose. Finally, a major finding of this review is the need to improve the quality and quantity of dietary intervention studies for patients with liver cirrhosis, particularly with the use of partial or whole dietary sources. In conclusion, dietary management of cirrhosis is not a one-size fits all approach but should be implemented earlier on in the treatment algorithm to improve the clinical prognosis of cirrhosis.
