Nutritional status in patients with chronic pancreatitis and liver cirrhosis is related to disease conditions and not dietary habits. Sci Rep 2024; 14:4700. [PMID: 38409360 PMCID: PMC10897307 DOI: 10.1038/s41598-024-54998-7] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/23/2023] [Accepted: 02/19/2024] [Indexed: 02/28/2024] Open
Abstract
Malnutrition is a common complication of chronic pancreatitis (CP) and liver cirrhosis (LC). Inadequate food intake is considered a relevant driver of malnutrition in both entities. However, the contribution of habitual diet to impaired nutritional status is unclear. In a prospective, multicenter cross-sectional study, we recruited patients with confirmed CP or LC and healthy volunteers as a control group. Malnutrition was diagnosed according to the Global Leadership Initiative on Malnutrition criteria. We comprehensively investigated habitual dietary intake on nutrient, food group, and dietary pattern level applying two validated food frequency questionnaires. We included 144 patients (CP: n = 66; LC: n = 78) and 94 control subjects. Malnutrition was prevalent in 64% and 62% of patients with CP or LC, respectively. In both CP and LC, despite slightly altered food group consumption in malnourished and non-malnourished patients there were no differences in energy or nutrient intake as well as dietary quality. Compared to controls patients showed distinct dietary food group habits. Patients consumed less alcohol but also lower quantities of fruits and vegetables as well as whole grain products (p < 0.001, respectively). Nevertheless, overall dietary quality was comparable between patients and healthy controls. Nutritional status in CP and LC patients is rather related to disease than habitual dietary intake supporting the relevance of other etiologic factors for malnutrition such as malassimilation or chronic inflammation. Despite distinct disease-related differences, overall dietary quality in patients with CP or LC was comparable to healthy subjects, which suggests susceptibility to dietary counselling and the benefits of nutrition therapy in these entities.

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.

Use of Branched-Chain Amino Acids as a Potential Treatment for Improving Nutrition-Related Outcomes in Advanced Chronic Liver Disease. Nutrients 2023; 15:4190. [PMID: 37836474 PMCID: PMC10574343 DOI: 10.3390/nu15194190] [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: 09/02/2023] [Revised: 09/19/2023] [Accepted: 09/20/2023] [Indexed: 10/15/2023] Open
Abstract
Advanced chronic liver disease (ACLD) represents a complex and multifactorial clinical entity characterized by liver dysfunction and associated complications. In recent years, the significance of nutritional status in ACLD prognosis has gained considerable attention. This review article delves into the multifactorial pathogenesis of malnutrition in ACLD and its profound consequences for health outcomes. We explore the clinical implications of secondary sarcopenia in ACLD and highlight the critical relevance of frailty in both decompensated and compensated ACLD. A specific focus of this review revolves around branched-chain amino acids (BCAAs) and their pivotal role in managing liver disease. We dissect the intricate relationship between low Fischer's ratio and BCAA metabolism in ACLD, shedding light on the molecular mechanisms involved. Furthermore, we critically evaluate the existing evidence regarding the effects of BCAA supplementation on outcomes in ACLD patients, examining their potential to ameliorate the nutritional deficiencies and associated complications in this population.

Abstract
The liver is a key organ that is responsible for the metabolism of proteins, fats, and carbohydrates and the absorption and storage of micronutrients. Unfortunately, the prevalence of chronic liver diseases at various stages of advancement in the world population is significant. Due to the physiological function of the liver, its dysfunction can lead to malnutrition and sarcopenia, and the patient's nutritional status is an important prognostic factor. This review discusses key issues related to the diet therapy of patients with chronic liver diseases, as well as those qualified for liver transplantation and in the postoperative period.

Systematic review with meta-analysis: Branched-chain amino acid supplementation in liver disease. Eur J Clin Invest 2023; 53:e13909. [PMID: 36394355 DOI: 10.1111/eci.13909] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/29/2022] [Revised: 11/04/2022] [Accepted: 11/13/2022] [Indexed: 11/19/2022]
Abstract
BACKGROUND Dietary supplementation with branched-chain amino acids (BCAA) is often used in cirrhotic patients to improve nutritional status. We wanted to explore the evidence for BCAA supplementation in chronic liver disease. METHODS We searched MEDLINE and EMBASE for studies with BCAA supplementation with the presence of a disease-control group (placebo or no intervention) using search terms 'liver cirrhosis', 'hepatocellular carcinoma', 'branched chain amino acids' and relevant synonyms. Risk of bias was assessed using ROBINS-I and RoB 2.0 tools. Meta-analyses were performed with a random-effects model. Results were reported following EQUATOR guidelines. RESULTS Of 3378 studies screened by title and abstract, 54 were included (34 randomized controlled trials, 5 prospective case-control studies, 13 retrospective case-control studies: in total 2308 patients BCAA supplementation, 2876 disease-controls). Risk of bias was high/serious for almost all studies. According to meta-analyses, long-term (at least 6 months) BCAA supplementation in cirrhotic patients significantly improved event-free survival (p = .008; RR .61 95% CI .42-.88) and tended to improve overall survival (p = .05; RR .58 95% CI .34-1.00). Two retrospective studies suggested the beneficial effects during sorafenib for hepatocellular carcinoma. Available studies reported no beneficial effects or contradictory results of BCAA after other specific therapeutic interventions (resection or radiological interventions for hepatocellular carcinoma, liver transplantation, paracentesis or variceal ligation). No convincing beneficial effects of BCAA supplementation on liver function, nutritional status or quality of life were found. No study reported serious side effects of BCAA. CONCLUSIONS Prophylactic BCAA supplementation appears safe and might improve survival in cirrhotic patients.

Predictors of Morbidity and Mortality After Colorectal Surgery in Patients With Cirrhotic Liver Disease–A Retrospective Analysis of 54 Cases at a Tertiary Care Center. Front Med (Lausanne) 2022; 9:886566. [PMID: 35814748 PMCID: PMC9257019 DOI: 10.3389/fmed.2022.886566] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2022] [Accepted: 05/24/2022] [Indexed: 11/13/2022] Open
Abstract
BackgroundDespite various existing scores that predict morbidity and mortality of patients with cirrhotic liver disease (CLD), data on specific risk stratification of patients with CLD undergoing colorectal surgery (CRS) are rare. The aim of this study was to assess in-hospital morbidity and mortality of patients with liver cirrhosis scheduled for CRS, with specific focus on possible pitfalls of surgery in this special cohort.MethodsBetween 1996 and 2018, 54 patients with CLD undergoing CRS were identified and included in this study cohort. Postoperative morbidity and mortality were assessed using the Clavien/Dindo (C/D) classification as well as by type of complication. Univariate and multivariate analyses were performed to analyze the predictive factors for increased postoperative morbidity.ResultsOf the patients, 37% patients died during the procedure or postoperatively. Major complications were seen in 23.1% of patients (>C/D IIIb). Patients with Child B or C cirrhosis as well as patients undergoing emergency surgery experienced significantly more major complications (p = 0.04 and p = 0.023, respectively). The most common complications were bleeding requiring blood transfusion (51.1%) and cardiocirculatory instability due to bleeding or sepsis (44.4%). In 53.7% of patients, an anastomosis was created without a protective ostomy. Anastomotic leakage occurred in 20.7% of these patients. Multivariate analysis showed that a primary anastomosis without a protective ostomy was the strongest risk factor for major complications (p = 0.042).DiscussionMorbidity and mortality after CRS in patients with CLD remains high and is not only influenced by liver function but also by surgical variables. Considering the high rate of anastomotic leakage, creating a protective or definitive ostomy must be considered with regard to the underlying pathology, the extent of CLD, and the patient's condition. Moreover, our data suggest that surgery in these most fragile patients should be performed only in experienced centers with immediate contact to hepatologists and experts in hemostasis.

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.

The use of prealbumin as a predictor of malnutrition in cirrhotic patients and the effect of nutritional support in patients with low prealbumin levels. Turk J Med Sci 2020; 50:398-404.

Abstract
Background/aim Malnutrition is an important and commonly seen prognostic factor in patients with cirrhosis. The diagnosis of malnutrition in cirrhosis patients may be challenging, and an easily measured and widely usable marker is lacking. Prealbumin, however, is an easily measured marker. In the current study we measured prealbumin levels in cirrhotic patients with no clinically apparent malnutrition and used it as a malnutrition marker. Another aim of this study was to evaluate the effect of nutritional support on patient with low prealbumin levels. Materials and methods Fifty-two patients with Child A and Child B cirrhosis were selected for the study. Prealbumin levels were studied, and Child and MELD scores were calculated. Patients with prealbumin levels ˂180 mg/L were considered to have malnutrition, and two different types of nutritional products were given to these patients. The patients given nutritional support were investigated a month later, and parameters were compared. Results According to the prealbumin threshold of 180 mg/L, malnutrition frequencies were 59.3% for Child A and 95% for Child B cirrhosis. After the provision of nutritional support statistically significant improvements in albumin and INR levels were detected. In addition, the MELD score decreased; however, it was not statistically significant (P: 0.088). A statistically significant decrease in the MELD score was only obtained in patients with Child B cirrhosis (P: 0.033). When the oral replacement therapies were investigated separately, a statistically significant decrease in MELD scores was detected with product 1 (P: 0.043). Conclusion Prealbumin can be used as an easily measured parameter for earlier detection of malnutrition in patients with cirrhosis and without clinically apparent malnutrition. Oral nutritional support, especially with products containing relatively high carbohydrate levels and low protein, may have a favorable effect on MELD scores.

Abstract
OBJECTIVE The objective was to explore the characteristics of energy metabolism in patients with alcoholic liver cirrhosis (ALC) and diabetes mellitus (DM). METHODS Thirty-four male patients with ALC and DM, 30 male patients with ALC without DM and 10 male healthy controls (HC) were enrolled in this study. Resting energy expenditure (REE), respiratory quotient (RQ) were measured by indirect calorimetry. Data were analyzed using the Student's t-test, Mann-Whitney U-test and χ2 tests between two groups. Logistic regression analysis was used to analyze the risk factors for hypermetabolism. RESULTS Measured REE was significantly higher in patients with ALC and DM (1740 ± 338 kcal/d) than in patients with ALC (1400 ± 304 kcal/d, P < 0.01). Fasting blood glucose was an independent factor predicting hypermetabolism in all of the patients with ALC (P = 0.005). RQ was lower in patients with ALC and DM (0.80 ± 0.06) than in patients with ALC (0.83 ± 0.05, P = 0.027) and the HC (0.86 ± 0.03, P = 0.001). In the ALC and DM group, measured REE as percentage of predicted REE by Harris-Benedict formula was higher in patients with HbA1c ≥ 7.5% than in those with HbA1c < 7.5% (126.36 ± 15.19% vs. 109.48 ± 23.89%, P = 0.040). CONCLUSION REE was increased and RQ was significantly decreased in patients with ALC and DM. These changes were associated with poor glucose control. HbA1c less than 7.5% may reduce the risk of hypermetabolism.

Abstract
Hepatic encephalopathy (HE) is a potentially reversible neurocognitive condition seen in patients with advanced liver disease. The overt form of HE has been reported in up to 45% of patients with cirrhosis. This debilitating condition is associated with increased morbidity and mortality and imposes a significant burden on the caregivers and healthcare system. After providing an overview of HE epidemiology and pathophysiology, this review focuses on the interaction of HE and frailty, nutrition requirements and recommendations in cirrhotic patients with HE, and current dietary and pharmacologic options for HE treatment.

Abstract
BACKGROUND Sarcopenia, i.e., muscle loss is now a well-recognized complication of cirrhosis and in cases of non-alcoholic fatty liver disease can contribute to accelerate liver fibrosis leading to cirrhosis. Hence, it is imperative to study interventions which targets to improve sarcopenia in cirrhosis.
AIM To examine the relationship between interventions such nutritional supplementation, exercise, combined life style intervention, testosterone replacement and trans jugular intrahepatic portosystemic shunt (TIPS) to improve muscle mass in cirrhosis.
METHODS We search PubMed, EMBASE and Cochrane between June-August 2018, without a limiting period and the types of articles (RCTs, clinical trial, comparative study) in adult patients with sarcopenia and cirrhosis. The primary outcome of interest was improvement in muscle mass, strength and physical function interventions mentioned above. In the screening process, 154 full text articles were included in the review and 129 studies were excluded.
RESULTS We identified 24 studies that met review inclusion criteria. The studies were diverse in terms of the design, setting, interventions, and outcome measurements. We performed only qualitative synthesis of evidence due to heterogeneity amongst studies. Risk of bias was medium in most of the included studies and low quality of evidence showed improvement in the muscle mass, strength and physical function following aerobic exercise. 60% of the included studies on the nutritional intervention, 100% of the studies on testosterone replacement in hypogonadal men and trans-jugular portosystemic shunt were proved to be effective in improving sarcopenia in cirrhosis.
CONCLUSION Although the quality of evidence is low, the findings of our systematic review suggest improvement in the sarcopenia in cirrhosis with exercise, nutritional interventions, hormonal and TIPS interventions. High quality randomized controlled trials needed to further strengthen these findings.

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
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.

Abstract
Alcohol consumption accounts for 3.8% of annual global mortality worldwide, and the majority of these deaths are due to alcoholic liver disease (ALD), mainly alcoholic cirrhosis. ALD is one of the most common indications for liver transplantation (LT). However, it remains a complicated topic on both medical and ethical grounds, as it is seen by many as a “self-inflicted disease”. One of the strongest ethical arguments against LT for ALD is the probability of relapse. However, ALD remains a common indication for LT worldwide. For a patient to be placed on an LT waiting list, 6 mo of abstinence must have been achieved for most LT centers. However, this “6-mo rule” is an arbitrary threshold and has never been shown to affect survival, sobriety, or other outcomes. Recent studies have shown similar survival rates among individuals who undergo LT for ALD and those who undergo LT for other chronic causes of end-stage liver disease. There are specific factors that should be addressed when evaluating LT patients with ALD because these patients commonly have a high prevalence of multisystem alcohol-related changes. Risk factors for relapse include the presence of anxiety or depressive disorders, short pre-LT duration of sobriety, and lack of social support. Identification of risk factors and strengthening of the social support system may decrease relapse among these patients. Family counseling for LT candidates is highly encouraged to prevent alcohol consumption relapse. Relapse has been associated with unique histopathological changes, graft damage, graft loss, and even decreased survival in some studies. Research has demonstrated the importance of a multidisciplinary evaluation of LT candidates. Complete abstinence should be attempted to overcome addiction issues and to allow spontaneous liver recovery. Abstinence is the cornerstone of ALD therapy. Psychotherapies, including 12-step facilitation therapy, cognitive-behavioral therapy, and motivational enhancement therapy, help support abstinence. Nutritional therapy helps to reverse muscle wasting, weight loss, vitamin deficiencies, and trace element deficiencies associated with ALD. For muscular recovery, supervised physical activity has been shown to lead to a gain in muscle mass and improvement of functional activity. Early LT for acute alcoholic hepatitis has been the subject of recent clinical studies, with encouraging results in highly selected patients. The survival rates after LT for ALD are comparable to those of patients who underwent LT for other indications. Patients that undergo LT for ALD and survive over 5 years have a higher risk of cardiorespiratory disease, cerebrovascular events, and de novo malignancy.

Abstract
PURPOSE Major hepatic resections are performed for primary hepatobiliary malignancies, metastatic disease, and benign lesions. Patients with chronic liver disease, including cirrhosis and steatosis, are at an elevated risk of malnutrition and impaired strength and exercise capacity, deficits which cause increased risk of postoperative complications and mortality. The aims of this report are to discuss the pathophysiology of changes in nutrition, exercise capacity, and muscle strength in patient populations likely to require major hepatectomy, and review recommendations for preoperative evaluation and optimization. METHODS Nutritional and functional impairment in preoperative hepatectomy patients, especially those with underlying liver disease, have a complex and multifactorial physiologic basis that is not completely understood. RESULTS Recognition of malnutrition and compromised strength and exercise tolerance preoperatively can be difficult, but is critical in providing the opportunity to intervene prior to major hepatic resection and potentially improve postoperative outcomes. There is promising data on a variety of nutritional strategies to ensure adequate intake of calories, proteins, vitamins, and minerals in patients with cirrhosis and reduce liver size and degree of fatty infiltration in patients with hepatic steatosis. Emerging evidence supports structured exercise programs to improve exercise tolerance and counteract muscle wasting. CONCLUSIONS The importance of nutrition and functional status in patients indicated for major liver resection is apparent, and emerging evidence supports structured preoperative preparation programs involving nutritional intervention and exercise training. Further research is needed in this field to develop optimal protocols to evaluate and treat this heterogeneous cohort of patients.

Methods 59 consecutive cirrhotic patients with refractory ascites unresponsive to outpatient treatment. Enrolled subjects were randomized to treatment with intravenous infusion of furosemide (125–250mg⁄bid) plus small volumes of HSS from the first day after admission until 3 days before discharge (Group A, n:38), or repeated paracentesis from the first day after admission until 3 days before discharge (Group B, n: 21). Plasma levels of ANP, BNP, Leptin, visfatin, IL-1β, TNF-a, IL-6 were measured before and after the two type of treatment. Results Subjects in group A were observed to have a significant reduction of serum levels of TNF-α, IL-1β, IL-6, ANP, BNP, and visfatin, thus regarding primary efficacy endpoints, in Group A vs. Group B we observed higher Δ-TNF-α, Δ-IL-1β, Δ-IL-6, Δ-ANP, Δ-BNP, Δ-visfatin, Δ-Leptin at discharge. Discussion Our findings underline the possible inflammatory and metabolic effect of saline overload correction in treatment of cirrhosis complications such as refractory ascites, suggesting a possible role of inflammatory and metabolic-nutritional variables as severity markers in these patients.

Abstract
Malnutrition is the most frequent and nearly universal consequence in alcoholic liver disease (ALD) that adversely affects clinical outcomes. Sarcopenia or skeletal muscle loss is the major component of malnutrition in liver disease. There are no effective therapies to prevent or reverse sarcopenia in ALD because the mechanisms are not well understood. Consequences of liver disease including hyperammonemia, hormonal perturbations, endotoxemia and cytokine abnormalities as well as the direct effects of alcohol and its metabolites contribute to sarcopenia in ALD. This article focuses on the prevalence, methods to quantify malnutrition, specifically sarcopenia and potential therapies including novel molecular targeted treatments.

Undernutrition, risk of malnutrition and obesity in gastroenterological patients: A multicenter study. World J Gastrointest Oncol 2016; 8:563-572. [PMID: 27559436 PMCID: PMC4942745 DOI: 10.4251/wjgo.v8.i7.563] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/22/2015] [Revised: 03/23/2016] [Accepted: 04/22/2016] [Indexed: 02/05/2023] Open
Abstract
AIM: To investigate the prevalence of undernutrition, risk of malnutrition and obesity in the Italian gastroenterological population.
METHODS: The Italian Hospital Gastroenterology Association conducted an observational, cross-sectional multicenter study. Weight, weight loss, and body mass index were evaluated. Undernutrition was defined as unintentional weight loss > 10% in the last three-six months. Values of Malnutrition Universal Screening Tool (MUST) > 2, NRS-2002 > 3, and Mini Nutritional Assessment (MNA) from 17 to 25 identified risk of malnutrition in outpatients, inpatients and elderly patients, respectively. A body mass index ≥ 30 indicated obesity. Gastrointestinal pathologies were categorized into acute, chronic and neoplastic diseases.
RESULTS: A total of 513 patients participated in the study. The prevalence of undernutrition was 4.6% in outpatients and 19.6% in inpatients. Moreover, undernutrition was present in 4.3% of the gastrointestinal patients with chronic disease, 11.0% of those with acute disease, and 17.6% of those with cancer. The risk of malnutrition increased progressively and significantly in chronic, acute and neoplastic gastrointestinal diseases in inpatients and the elderly population. Logistical regression analysis confirmed that cancer was a risk factor for undernutrition (OR = 2.7; 95%CI: 1.2-6.44, P = 0.02). Obesity and overweight were more frequent in outpatients.
CONCLUSION: More than 63% of outpatients and 80% of inpatients in gastroenterological centers suffered from significant changes in body composition and required specific nutritional competence and treatment.

Handgrip dynamometry: a surrogate marker of malnutrition to predict the prognosis in alcoholic liver disease. Ann Gastroenterol 2016; 29:509-514. [PMID: 27708519 PMCID: PMC5049560 DOI: 10.20524/aog.2016.0049] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/07/2016] [Accepted: 03/26/2016] [Indexed: 12/12/2022] Open
Abstract
BACKGROUND The aim of the study was to determine the utility of handgrip dynamometry (HGD) in predicting short term mortality and complications in alcoholic liver disease. METHODS Patients with alcoholic liver disease were included and nutritional assessment was done using the Subjective Global Assessment (SGA), HGD and other conventional parameters. Mortality rates and complications were compared to nutritional status. RESULTS 80 patients were included in the study. Mean age of patients was 43.06±10.03 years. 69 patients survived and 11 patients died within the 3 month study duration. Handgrip strength (HGS) was higher in SGA A (28.76±5.48 kg) than SGA B (22.43±4.95 kg) and SGA C (16.78±3.83 kg) (P=<0.001). Number of complications including spontaneous bacterial Peritonitis, gastrointestinal bleeding and encephalopathy in SGA C group were 66.66%, in SGA B 20.75% and SGA A 10%. Mean HGS was significantly higher in the survivors (24.23±5.86) compared to non-survivors (18.04±4.82) (P=0.0011). There was a strong negative correlation between the HGS and Child-Pugh score (P=<0.0012). Multivariate logistic regression analysis to assess the risk factors for death showed handgrip to be in the suggestive significance range (P=0.072). The sensitivity of HGS was 88.41% in predicting short term mortality. CONCLUSIONS HGS correlates with Child-Pugh score in predicting short term mortality. HGD is a simple, inexpensive and sensitive tool for assessing the nutritional status in alcoholic liver disease and can reliably predict its complications and survival.

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
We aimed to elucidate the incidence of protein-energy malnutrition (PEM) in patients with chronic liver disease and to identify factors linked to the presence of PEM.A total of 432 patients with chronic liver disease were analyzed in the current analysis. We defined patients with serum albumin level of ≤3.5 g/dL and nonprotein respiratory quotient (npRQ) value using indirect calorimetry less than 0.85 as those with PEM. We compared between patients with PEM and those without PEM in baseline characteristics and examined factors linked to the presence of PEM using univariate and multivariate analyses.There are 216 patients with chronic hepatitis, 123 with Child-Pugh A, 80 with Child-Pugh B, and 13 with Child-Pugh C. Six patients (2.8%) had PEM in patients with chronic hepatitis, 17 (13.8%) in patients with Child-Pugh A, 42 (52.5%) in patients with Child-Pugh B, and 10 (76.9%) in patients with Child-Pugh C (P < 0.001). Multivariate analysis revealed that Child-Pugh classification (P < 0.001), age ≥64 years (P = 0.0428), aspartate aminotransferase (AST) ≥40 IU/L (P = 0.0023), and branched-chain amino acid to tyrosine ratio (BTR) ≤5.2 (P = 0.0328) were independent predictors linked to the presence of PEM. On the basis of numbers of above risk factors (age, AST, and BTR), the proportions of patients with PEM were well stratified especially in patients with early chronic hepatitis or Child-Pugh A (n = 339, P < 0.0001), while the proportions of patients with PEM tended to be well stratified in patients with Child-Pugh B or C (n = 93, P = 0.0673).Age, AST, and BTR can be useful markers for identifying PEM especially in patients with early stage of chronic liver disease.

Abstract
AIM: To evaluate the practice of nutritional assessment and management of hospitalised patients with cirrhosis and the impact of malnutrition on their clinical outcome.
METHODS: This was a retrospective cohort study on patients with liver cirrhosis consecutively admitted to the Department of Gastroenterology and Hepatology at the Royal Adelaide Hospital over 24 mo. Details were gathered related to the patients’ demographics, disease severity, nutritional status and assessment, biochemistry and clinical outcomes. Nutritional status was assessed by a dietician and determined by subjective global assessment. Estimated energy and protein requirements were calculated by Simple Ratio Method. Intake was estimated from dietary history and/or food charts, and represented as a percentage of estimated daily requirements. Median duration of follow up was 14.9 (0-41.4) mo.
RESULTS: Of the 231 cirrhotic patients (167 male, age: 56.3 ± 0.9 years, 9% Child-Pugh A, 42% Child-Pugh B and 49% Child-Pugh C), 131 (57%) had formal nutritional assessment during their admission and 74 (56%) were judged to have malnutrition. In-hospital caloric (15.6 ± 1.2 kcal/kg vs 23.7 ± 2.3 kcal/kg, P = 0.0003) and protein intake (0.65 ± 0.06 g/kg vs 1.01 ± 0.07 g/kg, P = 0.0003) was significantly reduced in patients with malnutrition. Of the malnourished cohort, 12 (16%) received enteral nutrition during hospitalisation and only 6 (8%) received ongoing dietetic review and assessment following discharge from hospital. The overall mortality was 51%, and was higher in patients with malnutrition compared to those without (HR = 5.29, 95%CI: 2.31-12.1; P < 0.001).
CONCLUSION: Malnutrition is common in hospitalised patients with cirrhosis and is associated with higher mortality. Formal nutritional assessment, however, is inadequate. This highlights the need for meticulous nutritional evaluation and management in these patients.

Abstract
As many as 80% of patients with end-stage liver disease and hepatic encephalopathy have significant protein-calorie malnutrition. Because of the severe hypercatabolic state of cirrhosis, the provision of liberal amounts of carbohydrate (at least 35 to 40 kcal/kg per day), and between 1.2 and 1.6 g/kg of protein is necessary. Protein restriction is not recommended. Branched-chain amino acid supplementation and vegetable protein are associated with improved outcomes. Dietary supplementation with vitamins, minerals (with the notable exception of zinc) and probiotics should be decided on a case-by-case basis.

Abstract
Liver cirrhosis (LC) patients often have protein-energy malnutrition (PEM) and decreased physical activity. These conditions often lead to sarcopenia, which is the loss of skeletal muscle volume and increased muscle weakness. Recent studies have demonstrated that PEM and sarcopenia are predictors for poor survival in LC patients. Nutrition and exercise management can improve PEM and sarcopenia in those patients. Nutrition management includes sufficient dietary intake and improved nutrient metabolism. With the current high prevalence of obesity, the number of obese LC patients has increased, and restriction of excessive caloric intake without the exacerbation of impaired nutrient metabolism is required for such patients. Branched chain amino acids are good candidates for supplemental nutrients for both obese and non-obese LC patients. Exercise management can increase skeletal muscle volume and strength and improve insulin resistance; however, nutritional status and LC complications should be assessed before an exercise management regimen is implemented in LC patients. The establishment of optimal exercise regimens for LC patients is currently required. In this review, we describe nutritional status and its clinical impact on the outcomes of LC patients and discuss general nutrition and exercise management in LC patients.

Abstract
OBJECTIVES The aim of this study was to evaluate the energy balance (EB) of patients on the waiting list for liver transplantation, using total energy expenditure (TEE) assessment and total caloric intake (TCI). METHODS We analyzed nutrient adequacy and factors associated with it. EB was obtained by subtracting the TCI (obtained by 3-d food record) from TEE, which was measured as resting energy expenditure and physical activity factor calculation. Socioeconomic and clinical data also were evaluated. Univariate and multiple linear regressions were used (P < 0.05). Seventy-three patients were included. RESULTS The TEE was 2318.5 kcal, and the TCI was 1485.1 kcal, with 81.6% of patients presenting with negative EB. There was no significant association between TCI and socioeconomic variables, medications, and encephalopathy (P > 0.05). Women, less-educated patients, those with ascites, and those who were malnourished presented with lower TCI (P < 0.05). Severity of disease, by Child-Pugh and Model for End-Stage Liver Disease scores were associated with EB (P < 0.05). Child-Pugh remained significant after multivariate analyses. Energy inadequacy was observed in 91.8% of patients, and protein inadequacy in 72.6% of patients. Polyunsaturated fatty acid (64.4%) and monounsaturated fatty acid (91.8%) and fiber (94.5%) inadequacies also were high. The percentage of adequate intake was less than 10% for vitamins B5 and D, calcium, folic acid, and potassium, and higher percentages of adequate intake (>80%) were found for iron and vitamins B1 and B12. Moreover, 54.8% and 16.4% of the patients had excessive sodium and cholesterol intakes, respectively. CONCLUSION Negative EB was highly prevalent among patients on the waiting list for liver transplantation, and was associated with the severity of liver disease. Negative EB was primarily affected by low food intake. The food intake data were characterized by low overall energy and protein intake and inadequate composition of the patient's diet plan, which tended to be characterized by specific nutrient deficiencies and excesses.

Abstract
OPINION STATEMENT Liver transplantation is the definitive therapy for cirrhosis, and malnutrition is the most frequent complication in these patients. Sarcopenia or loss of muscle mass is the major component of malnutrition in cirrhotics and adversely affects their outcome. In addition to the metabolic consequences, functional consequences of sarcopenia include reduced muscle strength and deconditioning. Despite nearly universal occurrence of sarcopenia and its attendant complications, there are no established therapies to prevent or reverse the same. Major reasons for this deficiency include the lack of established standardized definitions or measures to quantify muscle mass, as well as paucity of mechanistic studies or identified molecular targets to develop specific therapeutic interventions. Anthropometric evaluation, bioelectrical impedance analysis, and DEXA scans are relatively imprecise measures of muscle mass, and recent data on imaging measures to determine muscle mass accurately are likely to allow well-defined outcome responses to treatments. Resurgence of interest in the mechanisms of muscle loss in liver disease has been directly related to the rapid advances in the field of muscle biology. Metabolic tracer studies on whole body kinetics have been complemented by direct studies on the skeletal muscle of cirrhotics. Hypermetabolism and anabolic resistance contribute to sarcopenia. Reduced protein synthesis and increased autophagy have been reported in cirrhotic skeletal muscle, while the contribution of the ubiquitin-proteasome pathway is controversial. Increased plasma concentration and skeletal muscle expression of myostatin, a TGFβ superfamily member that causes reduction in muscle mass, have been reported in cirrhosis. Hyperammonemia and TNFα have been reported to increase myostatin expression and may be responsible for sarcopenia in cirrhosis. Nutriceutical interventions with leucine enriched amino acid mixtures, myostatin antagonists and physical activity hold promise as measures to reverse sarcopenia. There is even less data on muscle function and deconditioning in cirrhosis and studies in this area are urgently needed. Even though macronutrient replacement is a major therapeutic goal, micronutrient supplementation, specifically vitamin D, is expected to improve outcomes.

Abstract
BACKGROUND & AIMS Metabolic disorders and malnutrition are well known conditions reported in patients with liver disease (LD), but the relationship between them are underexplored. So, the aim of this study was to assess the resting energy expenditure (REE) of these patients, identifying the prevalence of hyper- and hypometabolism. In addition, to evaluate whether malnutrition and clinical variables were associated with REE and metabolic disorders. METHODS The REE was measured by indirect calorimetry and predicted by the Harris and Benedict formula (REEHB). Nutritional status was assessed by different methods. The etiology, severity and complications of LD were also evaluated. RESULTS A total of 81 patients were assessed. The measured REE was 1587.5 ± 426.6 kcal. The REE was overestimated by the REEHB (REE:REEHB <0.8) in 7.4% and underestimated (REE:REEHB >1.2) in 24.7% of the patients. The REE was lower in malnourished patients (p < 0.05). However, hyper- and hypometabolism were not associated with nutritional status (p > 0.05). The REE and hypermetabolism were not associated with LD, but hypometabolic patients had a higher prevalence of Child C, and had higher values for MELD, INR and total bilirubin (p < 0.05). After multiple regression analyses, the REE was significantly associated (p < 0.05) with intracellular body water, arm muscle area and serum glucose. Serum glucose was only significantly associated (p < 0.05) with hypermetabolism, and INR with hypometabolism. CONCLUSION Changes in resting metabolism are present but not universal. The hypermetabolism was associated with extrahepatic factors, and hypometabolism with the severity of LD. Under these conditions in the clinical setting, calculated energy requirements using the HB formula should be adjusted.

Abstract
Deficiencies in vitamins A, D, and E have been linked to night blindness, bone health, and post-liver transplant reperfusion injury. The aim of this study was to determine the prevalence and predictive factors of fat-soluble vitamin deficiencies in liver transplant candidates. We reviewed the medical records of liver transplant candidates at our center from January 2008 to September 2011. The etiology of cirrhosis, Model for End-Stage Liver Disease score, Child-Pugh class, body mass index (BMI), and vitamin A, vitamin E, and vitamin 25-OH-D levels were recorded. Patients were excluded for incomplete laboratory data, short gut syndrome, celiac disease, pancreatic insufficiency, or prior liver transplantation. Sixty-three patients were included. The most common etiologies of liver disease were alcohol (n = 23), hepatitis C virus (n = 19), and nonalcoholic steatohepatitis (n = 5). Vitamin A and D deficiencies were noted in 69.8% and 81.0%, respectively. Only 3.2% of the patients were vitamin E-deficient. There were no documented cases of night blindness. Twenty-five of the 55 patients with bone density measurements had osteopenia, and 10 had osteoporosis. Four patients had vertebral fractures. There was 1 case of posttransplant reperfusion injury in a patient with vitamin E deficiency. In a multivariate analysis, there were no statistically significant predictors for vitamin D deficiency. The Child-Pugh class [odds ratio (OR) = 6.84, 95% confidence interval (CI) = 1.52-30.86, P = 0.01], elevated total bilirubin level (OR = 44.23, 95% CI = 5.02-389.41, P < 0.001), and elevated BMI (OR = 1.17, 95% CI = 1.00-1.36, P = 0.045) were found to be predictors of vitamin A deficiency. In conclusion, the majority of liver disease patients evaluated for liver transplantation at our center had vitamin A and D deficiencies. The presence or absence of cholestatic liver disease did not predict deficiencies, whereas Child-Pugh class, bilirubin level, and elevated BMI predicted vitamin A deficiency.

Abstract
Background. Protein supplementation has been shown to be effective for the treatment of malnourished patients with liver cirrhosis. The parameters used to assess nutritional improvement in cirrhotic patients for such treatment are important. Objective. To evaluate the parameters for assessment of nutritional status in patients with liver cirrhosis after protein supplementation. Material and Method. A cross-sectional, prospective clinical trial with 22 cirrhotic patients was performed. Data from anthropometry, bioelectrical impedance, subjective global assessment (SGA), and visceral protein were gathered and analyzed to assess nutritional improvement after protein supplementation. Results. Twenty-two cirrhotic patients (mean age 52.9 ± 12.8 years; 54.5% male; 63.6% alcoholic cirrhosis; 63.6% Child-Pugh C) were recruited. After protein supplementation, a significant improvement was demonstrated in the SGA class A from 10 patients (45.5%) to 16 (72.7%) and 18 (81.8%) at the 4th and 8th weeks, respectively. Body weight, body mass index, and lean muscle mass were significantly increased from baseline at the 8th week. No significant change in other nutritional parameters was observed. Conclusions. The SGA and lean muscle mass were significant parameters in order to assess nutritional status in cirrhotic patients after protein supplementation.

Oral β-blockade in relation to energy expenditure in clinically stable patients with liver cirrhosis: a double-blind randomized cross-over trial. Metabolism 2012; 61:1547-53.

Abstract
Elevated resting energy expenditure (REE) is seen in liver cirrhosis and is associated with reduced transplant-free survival. Non-selective β-blockers reduce REE in acute hypermetabolic conditions. We examined whether non-selective β-blockers reduce REE in patients with stable liver cirrhosis. Twenty-two stable cirrhotic patients (Child-Pugh grading: 19A, 2B, 1C) were randomized to 3-month treatment with nadolol (titrated to decrease resting pulse rate by 20%) or placebo and after a 1-month washout period crossed to the alternative treatment for a further 3 months. REE was measured by indirect calorimetry and total body protein by neutron activation analysis at the beginning and end of each 3-month period of treatment. A predicted REE was calculated for each patient based on total body protein. A measured to predicted REE ratio >1.22 indicated significantly elevated REE. The primary outcome was REE at the end of 3-month treatment with nadolol compared with placebo. Elevated REE was seen in one patient at study entry. After 3 months on placebo REE was 1506±40 (SEM) kcal/d and on nadolol, 1476±40 kcal/d, a mean reduction of 31±16 kcal/d (P=.076). Total body protein changes were not significant. Nadolol was well tolerated with no increase in the rate of adverse events. In stable cirrhotic patients, nadolol was not associated with reduction in REE. A larger, longer-term study with different eligibility criteria is required to investigate whether this treatment offers benefits additional to its use for prevention of variceal hemorrhage.

Nutritional status in relation to lifestyle in patients with compensated viral cirrhosis. World J Gastroenterol 2012; 18:5759-70. [PMID: 23155318 PMCID: PMC3484346 DOI: 10.3748/wjg.v18.i40.5759] [Citation(s) in RCA: 28] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/03/2012] [Revised: 06/20/2012] [Accepted: 06/28/2012] [Indexed: 02/06/2023] Open
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
Surgery is often needed in patients with concurrent liver disease. The multiple physiological roles of the liver places these patients at an increased risk of morbidity and mortality. Diseases necessitating surgery like gallstones and hernia are more common in patients with cirrhosis. Assessment of severity of liver dysfunction before surgery is important and the risk benefit of the procedure needs to be carefully assessed. The disease severity may vary from mild transaminase rise to decompensated cirrhosis. Surgery should be avoided if possible in the emergency setting, in the setting of acute and alcoholic hepatitis, in a patient of cirrhosis who is child class C or has a MELD score more than 15 or any patient with significant extrahepatic organ dysfunction. In this subset of patients, all possible means to manage these patients conservatively should be attempted. Modified Child-Pugh scores and model for end-stage liver disease (MELD) scores can predict mortality after surgery fairly reliably including nonhepatic abdominal surgery. Pre-operative optimization would include control of ascites, correction of electrolyte imbalance, improving renal dysfunction, cardiorespiratory assessment, and correction of coagulation. Tests of global hemostasis like thromboelastography and thrombin generation time may be more predictive of the risk of bleeding compared with the conventional tests of coagulation in patients with cirrhosis. Correction of international normalized ratio with fresh frozen plasma does not necessarily mean reduction of bleeding risk and may increase the risk of volume overload and lung injury. International normalized ratio liver may better reflect the coagulation status. Recombinant factor VIIa in patients with cirrhosis needing surgery needs further study. Intra-operatively, safe anesthetic agents like isoflurane and propofol with avoidance of hypotension are advised. In general, nonsteroidal anti-inflammatory drug (NSAIDs) and benzodiazepines should not be used. Intra-abdominal surgery in a patient with cirrhosis becomes more challenging in the presence of ascites, portal hypertension, and hepatomegaly. Uncontrolled hemorrhage due to coagulopathy and portal hypertension, sepsis, renal dysfunction, and worsening of liver failure contribute to the morbidity and mortality in these patients. Steps to reduce ascitic leaks and infections need to be taken. Any patient with cirrhosis undergoing major surgery should be referred to a specialist center with experience in managing liver disease.

Abstract
AIM The Japanese Nutritional Study Group for Liver Cirrhosis (JNUS) was assembled in 2008 with the support of a Health Labor Sciences Research Grant from the Ministry of Health, Labor and Welfare of Japan. The goal of the study group was to propose new nutritional guidelines for Japanese patients with liver cirrhosis (LC), with the aim of preventing hepatocellular carcinoma. METHODS Between 2008 and 2010, the member investigators of JNUS conducted various clinical and experimental studies on nutrition on LC. These included anthropometric studies, a questionnaire study on daily nutrient intake, clinical trials, experimental studies using animal models, re-evaluation of previous publications and patient education. Over this 3-year period, the group members regularly discussed the nutritional issues related to LC, and a proposal was finally produced. RESULTS Based on the results of JNUS projects and discussions among the members, general recommendations were made on how Japanese patients with LC should be managed nutritionally. These recommendations were proposed with a specific regard to the prevention of hepatocarcinogenesis. CONCLUSION The new JNUS guidelines on nutritional management for Japanese patients with LC will be useful for the actual nutritional management of patients with LC. The JNUS members hope that these guidelines will form the basis for future discussions and provide some direction in nutritional studies in the field of hepatology.

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
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
OBJECTIVE To develop a prognostic scoring system for risk stratification of patients with hepatic graft failure (GF) undergoing retransplants of the liver (ReLT) and improve patient selection. SUMMARY OF BACKGROUND DATA Retransplantation of the liver remains controversial because of inferior outcomes compared with the primary orthotopic liver transplantation (OLT) and raises concerns of inappropriate utilization of a scarce donor organ resource. Data on risk stratification of ReLT patients for long-term survival outcomes are limited. METHODS We conducted an analysis from our prospective database of 466 adults' ReLT between February 1984 and September 2010. Mean follow-up was 3 years. Each independent predictor for allograft failure was assigned risk score (RS) points of 1 or 2, proportional to the corresponding parameter estimate under the Cox model: Predictive index category (PIC) 1, RS = 0; PIC II, RS = 1 to 2; PIC III, RS = 3 to 4; and PIC IV, RS = 5 to 12. RESULTS Eight risk factors predictive for GF after ReLT included recipient age greater than 55 years, Model for End-Stage Liver Disease score greater than 27, history of prior OLT greater than 1, pre-ReLT requirement for mechanical ventilation, serum albumin less than 2.5 g/dL, donor age greater than 45 years, intraoperative requirement of packed red blood cell transfusion greater than 30 units, and performance of ReLT between 15 and 180 days from the prior OLT. Five-year GF-free survival was significantly higher in PIC I (65%) than in PIC II (53%), PIC III (43%), and PIC IV (20%) groups (P < 0.001). CONCLUSIONS This risk-stratification model was highly predictive of long-term outcome after liver retransplantation in adult recipients. This formula provides a practical guide for selection of candidates for retransplantation of the liver that can lead to improved patient outcomes and optimal utilization of a scarce resource.

Abstract
BACKGROUND Protein energy malnutrition frequently occurs in liver cirrhosis. Hand-grip strength according to Jamar is most reliable to predict protein energy malnutrition. We aimed to determine whether protein energy malnutrition affects complication risk. METHODS In 84 cirrhotics, baseline nutritional state was determined and subsequent complications prospectively assessed. Influence of potentially relevant factors including malnutrition (by Jamar hand-grip strength) on complication rates were evaluated with univariate analysis. Effect of malnutrition was subsequently evaluated by multivariate logistic regression with adjustment for possible confounders. RESULTS Underlying causes of cirrhosis were viral hepatitis in 31%, alcohol in 26%, and other in 43%. Baseline Child-Pugh (CP) class was A, B, or C in 58, 35, and 7%, respectively. Energy and protein intake decreased significantly with increasing CP class, with shift from proteins to carbohydrates. At baseline, according to Jamar hand-grip strength, malnutrition occurred in 67% (n=56). Malnutrition was associated with older age and higher CP class (CP class A 57%, B 79%, C 100%) but not with underlying disease or comorbidity. Complications occurred in 18 and 48% in well-nourished and malnourished patients, respectively, (P=0.007) during 13 ± 6 months follow-up. In multivariate analysis, malnutrition was an independent predictor of complications, after correcting for comorbidity, age, and CP score (adjusted odds ratio 4.230; 95% confidence interval 1.090-16.422; P=0.037). In univariate analysis, mortality (4 vs. 18%; P=0.1) tended to be worse in malnourished patients, but this trend was lost in multivariate analysis. CONCLUSION Malnutrition is an independent predictor of complications in cirrhosis.

Abstract
BACKGROUND AND AIMS We investigated whether in patients with liver cirrhosis reduced muscle strength is related to dysfunction of muscle mitochondria. METHODS The mitochondrial respiratory capacity of the tibial anterior muscle was evaluated in seven patients and eight healthy control subjects by 31P nuclear magnetic resonance spectroscopy (31PMRS) to express ATP turnover in vivo and by respirometry of permeabilized fibres from the same muscle to express the in vitro capacity for oxygen consumption. RESULTS Maximal voluntary contraction force for plantar extension was low in the patients (46% of the control value; P < 0.05), but neither the capacity for mitochondrial ATP synthesis, V(max-ATP) (0.38 ± 0.26 vs. 0.50 ± 0.07 mM s(-1) ; P = 0.13) nor the in vitro VO(2max) (0.52 ± 0.21 vs. 0.48 ± 0.21 μmol O2 (min g wet wt.)(-1) P = 0.25) were lowered correspondingly. Also, the activity of citrate synthesis and the respiratory chain complexes II and IV were similar in patients and controls. However during the contractions, the contribution to initial anaerobic ATP production from glycolysis relative to that from PCr was reduced in the patients (0.73 ± 0.22 vs. 0.99 ± 0.09; P < 0.01). CONCLUSIONS These results demonstrate that the markedly lower capacity for force generation in patients with liver cirrhosis is unrelated to their capacity for muscle ATP turnover, but the attenuated initial acceleration of anaerobic glycolysis suggests that these patients could be affected by a central limitation to force generation.

Abstract
PURPOSE OF REVIEW To review the most recent aspects of nutrition therapy of cirrhotic patients on the waiting list for liver transplantation. RECENT FINDINGS Undernutrition has been widely reported among these patients, despite the lack of consensus on the best nutritional assessment tools in this population. Nutrition therapy has been marked by controversy. Nonetheless, recent findings have pointed out to the important role of the nutrition status and of some specific nutrients on the outcome of these patients. SUMMARY We report the latest findings on nutrition care of patients with end-stage liver disease on the waiting list for liver transplantation such as the impact of the nutritional status on outcome, probiotic and branched-chain amino acid supplementation, as well as the use of immunomodulating formula. Another important strategy that has been shown to improve these patients' nutritional care is the offering of nocturnal meals and micronutrient supplementation.

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
AIM: To study and determine the resting energy expenditure (REE) and oxidation rates of glucose, fat and protein in severe chronic hepatitis B patients.
METHODS: A total of 100 patients with liver diseases were categorized into three groups: 16 in the acute hepatitis group, 56 in the severe chronic hepatitis group, and 28 in the cirrhosis group. The REE and the oxidation rates of glucose, fat and protein were assessed by indirect heat measurement using the CCM-D nutritive metabolic investigation system.
RESULTS: The REE of the severe chronic hepatitis group (20.7 ± 6.1 kcal/d per kg) was significantly lower than that of the acute hepatitis group (P = 0.014). The respiratory quotient (RQ) of the severe chronic hepatitis group (0.84 ± 0.06) was significantly lower than that of the acute hepatitis and cirrhosis groups (P = 0.001). The glucose oxidation rate of the severe hepatitis group (39.2%) was significantly lower than that of the acute hepatitis group and the cirrhosis group (P < 0.05), while the fat oxidation rate (39.8%) in the severe hepatitis group was markedly higher than that of the other two groups (P < 0.05). With improvement of liver function, the glucose oxidation rate increased from 41.7% to 60.1%, while the fat oxidation rate decreased from 26.3% to 7.6%.
CONCLUSION: The glucose oxidation rate is significantly decreased, and a high proportion of energy is provided by fat in severe chronic hepatitis. These results warrant a large clinical trail to assess the optimal nutritive support therapy for patients with severe liver disease.

Abstract
Malnutrition has increasingly been acknowledged as an important prognostic factor which can influence the clinical outcome of patients suffering from end-stage liver disease (ESLD). Despite the fact that malnutrition is not included in the Child-Pugh classification, its presence should alert clinicians to the same extent as do other complications, such as ascites and hepatic encephalopathy. The pathophysiological mechanisms and the clinical conditions that drive cirrhotic patients to an ill-balanced metabolic state are multiple and they intertwine. Inadequate offer of nutrients, the hypermetabolic state in cirrhosis, the diminished synthetic capacity of the liver and the impaired absorption of nutrients are the main reasons that disrupt the metabolic balance in ESLD. Identifying patients that are approaching the state of malnutrition by simple and easily applied methods is necessary in order to provide nutritional support to those that need it most. According to the European Society for Clinical Nutrition and Metabolism, simple bedside methods such as Subjective Global Assessment and anthropometric parameters are reliable in assessing the nutritional state of cirrhotic patients. Correcting the nutrient deficit of the affected patients is mandatory. Avoidance of alcohol and excess fat and ingestion of 4-6 meals/day containing carbohydrates and protein are the most common recommendations. In severe malnutrition, initiation of enteral feeding and/or use of special formulae such as branched-chain amino acid-enriched nutrient mixtures are often recommended. Enteral nutrition improves nutritional status and liver function, reduces complications, prolongs survival and is therefore indicated.

Abstract
BACKGROUND/AIMS Muscle wasting likely influences blood flow to muscle districts in advanced cirrhosis. Thus, we assessed systemic hemodynamics and femoral artery blood flow corrected by muscle mass of the lower limb in 13 patients (Child-Pugh classes B and C) and 11 healthy controls. METHODS Systemic hemodynamics were assessed by transthoracic electrical bioimpedance, femoral artery blood flow by duplex-Doppler and muscle mass by magnetic resonance imaging. RESULTS As expected, patients exhibited increased cardiac index and reduced peripheral vascular resistance. Femoral artery blood flow did not differ between patients and controls. However, when this parameter was indicized by the muscle mass of the lower limb, which was reduced in patients (median: 3391; range: [2546-4793] vs 5118 [3562-7077]cm3, p=0.0006), it proved almost doubled in patients (91.1 [59.9-119.4] vs 50.5 [38.6-69.8]microl/min cm3; p=0.0001). Patient femoral blood flow indicized by muscle mass correlated inversely with peripheral vascular resistance (r= -0.65; p=0.017) and directly with cardiac index (r=0.57; p=0.042). CONCLUSIONS Vasodilation of muscle districts contributes to the reduced peripheral vascular resistance in advanced cirrhosis. Our findings provide a stronger rationale for the use of non-selective vasoconstrictors to treat hemodynamic-dependent complications of cirrhosis, such as hepatorenal syndrome.

Abstract
Oxidative stress leads to chronic liver damage. Silybin has been conjugated with vitamin E and phospholipids to improve its antioxidant activity. Eighty-five patients were divided into 2 groups: those affected by nonalcoholic fatty liver disease (group A) and those with HCV-related chronic hepatitis associated with nonalcoholic fatty liver disease (group B), nonresponders to treatment. The treatment consisted of silybin/vitamin E/phospholipids. After treatment, group A showed a significant reduction in ultrasonographic scores for liver steatosis. Liver enzyme levels, hyperinsulinemia, and indexes of liver fibrosis showed an improvement in treated individuals. A significant correlation among indexes of fibrosis, body mass index, insulinemia, plasma levels of transforming growth factor-beta, tumor necrosis factor-alpha, degree of steatosis, and gamma-glutamyl transpeptidase was observed. Our data suggest that silybin conjugated with vitamin E and phospholipids could be used as a complementary approach to the treatment of patients with chronic liver damage.
