Abstract
GOALS We specifically evaluate the effect of malnutrition on the infection risks of patients admitted with alcoholic hepatitis using a national registry of hospitalized patients in the United States. BACKGROUND Malnutrition is a common manifestation of alcoholic hepatitis that affects patient outcomes. STUDY 2011 to 2017 National Inpatient Sample was used to isolated patients with alcoholic hepatitis, stratified using malnutrition (protein-calorie malnutrition, sarcopenia, and weight loss/cachexia) and matched using age, gender, and race with 1:1 nearest neighbor matching method. Endpoints included mortality and infectious endpoints. RESULTS After matching, there were 10,520 with malnutrition and 10,520 malnutrition-absent controls. Mortality was higher in the malnutrition cohort [5.02 vs. 2.29%, P<0.001, odds ratio (OR): 2.25, 95% confidence interval (CI): 1.93-2.63], as were sepsis (14.2 vs. 5.46, P<0.001, OR: 2.87, 95% CI: 2.60-3.18), pneumonia (10.9 vs. 4.63%, P<0.001, OR: 2.51, 95% CI: 2.25-2.81), urinary tract infection (14.8 vs. 9.01%, P<0.001, OR: 1.76, 95% CI: 1.61-1.91), cellulitis (3.17 vs. 2.18%, P<0.001, OR: 1.47, 95% CI: 1.24-1.74), cholangitis (0.52 vs. 0.20%, P<0.001, OR: 2.63, 95% CI: 1.59-4.35), and Clostridium difficile infection (1.67 vs. 0.91%, P<0.001, OR: 1.85, 95% CI: 1.44-2.37). In multivariate models, malnutrition was associated with mortality [P<0.001, adjusted odds ratio (aOR): 1.61, 95% CI: 1.37-1.90] and infectious endpoints: sepsis (P<0.001, aOR: 2.42, 95% CI: 2.18-2.69), pneumonia (P<0.001, aOR: 2.19, 95% CI: 1.96-2.46), urinary tract infection (P<0.001, aOR: 1.68, 95% CI: 1.53-1.84), cellulitis (P<0.001, aOR: 1.46, 95% CI: 1.22-1.74), cholangitis (P=0.002, aOR: 2.27, 95% CI: 1.36-3.80), and C. difficile infection (P<0.001, aOR: 1.89, 95% CI: 1.46-2.44). CONCLUSION This study shows the presence of malnutrition is an independent risk factor of mortality and local/systemic infections in patients admitted with alcoholic hepatitis.

Abstract
Coronavirus disease 2019 (COVID-19), which is caused by severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2), has affected millions of people globally. It was declared a pandemic by the World Health Organization in March 2020. The hyperinflammatory response to the entry of SARS-CoV-2 into the host through angiotensin-converting enzyme 2 is the result of a "cytokine storm" and the high oxidative stress responsible for the associated symptomatology. Not only respiratory symptoms are reported, but gastrointestinal symptoms (diarrhea, vomiting, and nausea) and liver abnormalities (high levels of aspartate aminotransferase, alanine aminotransferase transaminases, and bilirubin) are observed in at least 30% of patients. Reduced food intake and a delay in medical services may lead to malnutrition, which increases mortality and poor outcomes. This review provides some strategies to identify malnutrition and establishes nutritional approaches for the management of COVID-19 and liver injury, taking energy and nutrient requirements and their impact on the immune response into account. The roles of certain phytochemicals in the prevention of the disease or as promising target drugs in the treatment of this disease are also considered.

Abstract
BACKGROUND Malnutrition is a commonly encountered issue in patients with alcohol-associated liver disease. The role of nutritional supplementation in the management of alcohol-associated liver disease is integral to patient outcomes-it has been shown to decrease rates of hepatic encephalopathy, improve outcomes post-liver transplant, reduce 90-day hospital readmissions and lower mortality. Despite these benefits, many studies have shown nutritional support to be an underutilised tool in the care of patients with alcohol-associated liver disease. AIMS To review the epidemiology, pathophysiology, recommendations for nutritional assessment and supplementation, as well as future directions for research of the relationship between nutrition and alcohol-associated liver disease. METHODS A literature search was conducted via PubMed using MeSH terms to inform this narrative review. RESULTS Decreased dietary intake, socioeconomic status, impaired absorption of nutrients and increased free radical species are implicated in the pathophysiology of malnutrition in alcohol-associated liver disease. CONCLUSIONS Malnutrition is common in alcohol-associated liver disease, and physicians should be aware of its association with poor clinical outcomes. Routine nutritional assessment, involvement of a dietician and nutritional supplementation are recommended to improve clinical outcomes in patients with alcohol-associated liver disease.

Abstract
Malnutrition and issues of nutrition are common in hospitalized patients. Identifying patients at nutritional risk can help to improve hospital-related outcomes. Specialized nutritional support in the form of oral nutritional supplementation, enteral nutrition, and parenteral nutrition is essential to meeting the nutritional needs of many patients. Disease-specific nutritional considerations are fundamental to the quality care of hospitalized patients. Many vitamin, macronutrient, and micronutrient deficiencies are relevant in hospital setting.

Abstract
This update of evidence-based guidelines (GL) aims to translate current evidence and expert opinion into recommendations for multidisciplinary teams responsible for the optimal nutritional and metabolic management of adult patients with liver disease. The GL was commissioned and financially supported by ESPEN. Members of the guideline group were selected by ESPEN. We searched for meta-analyses, systematic reviews and single clinical trials based on clinical questions according to the PICO format. The evidence was evaluated and used to develop clinical recommendations implementing the SIGN method. A total of 85 recommendations were made for the nutritional and metabolic management of patients with acute liver failure, severe alcoholic steatohepatitis, non-alcoholic fatty liver disease, liver cirrhosis, liver surgery and transplantation as well as nutrition associated liver injury distinct from fatty liver disease. The recommendations are preceded by statements covering current knowledge of the underlying pathophysiology and pathobiochemistry as well as pertinent methods for the assessment of nutritional status and body composition.

Abstract
Malnutrition is associated with alcoholic liver disease (ALD) and related complications such as hepatic encephalopathy and increased rate of infections. Avoidance of prolonged fasting and overly restrictive diets is important to avoid poor nutrition. Adequate intake of calories, protein, and micronutrients via frequent small meals and evening supplements and/or enteral and parenteral nutrition when indicated has been associated with reduced mortality and morbidity in patients with ALD. Modification of protein/fat sources and composition in addition to probiotic supplementation are promising interventions for decreased progression of ALD and its complications.

Abstract
Malnutrition, both protein energy malnutrition (PEM) and deficiencies in individual nutrients, is a frequent complication of alcoholic liver disease (ALD). Severity of malnutrition correlates with severity of ALD. Malnutrition also occurs in patients with cirrhosis due to etiologies other than alcohol. The mechanisms for malnutrition are multifactorial, and malnutrition frequently worsens in the hospital due to fasting for procedures and metabolic complications of liver disease, such as hepatic encephalopathy. Aggressive nutritional support is indicated in inpatients with ALD, and patients often need to be fed through an enteral feeding tube to achieve protein and calorie goals. Enteral nutritional support clearly improves nutrition status and may improve clinical outcome. Moreover, late-night snacks in outpatient cirrhotics improve nutritional status and lean body mass. Thus, with no FDA-approved therapy for ALD, careful nutritional intervention should be considered as frontline therapy.

Abstract
Alcoholic liver disease (ALD) remains a major cause of liver-related mortality in the US and worldwide. The correct diagnosis of ALD can usually be made on a clinical basis in conjunction with blood tests, and a liver biopsy is not usually required. Abstinence is the hallmark of therapy for ALD, and nutritional therapy is the first line of therapeutic intervention. The role of steroids in patients with moderate to severe alcoholic hepatitis is gaining increasing acceptance, with the caveat that patients be evaluated for the effectiveness of therapy at 1 week. Pentoxifylline appears to be especially effective in ALD patients with renal dysfunction/hepatorenal syndrome. Biologics such as specific anti-TNFs have been disappointing and should probably not be used outside of the clinical trial setting. Transplantation is effective in patients with end-stage ALD who have stopped drinking (usually for ≥6 months), and both long-term graft and patient survival are excellent.

Abstract
Parenteral nutrition (PN) is indicated in alcoholic steatohepatitis (ASH) and in cirrhotic patients with moderate or severe malnutrition. PN should be started immediately when sufficientl oral or enteral feeding is not possible. ASH and cirrhosis patients who can be sufficiently fed either orally or enterally, but who have to abstain from food over a period of more than 12 hours (including nocturnal fasting) should receive basal glucose infusion (2–3 g/kg/d). Total PN is required if such fasting periods last longer than 72 h. PN in patients with higher-grade hepatic encephalopathy (HE); particularly in HE IV° with malfunction of swallowing and cough reflexes, and unprotected airways. Cirrhotic patients or patients after liver transplantation should receive early postoperative PN after surgery if they cannot be sufficiently rally or enterally nourished. No recommendation can be made on donor or organ conditioning by parenteral administration of glutamine and arginine, aiming at minimising ischemia/reperfusion damage. In acute liver failure artificial nutrition should be considered irrespective of the nutritional state and should be commenced when oral nutrition cannot be restarted within 5 to 7 days. Whenever feasible, enteral nutrition should be administered via a nasoduodenal feeding tube.

Abstract
Parenteral nutrition (PN) offers the possibility to increase or to ensure nutrient intake in patients, in whom sufficient nutrition by oral or enteral alone is insufficient or impossible. Complementary to the ESPEN guideline on enteral nutrition of liver disease (LD) patients the present guideline is intended to give evidence-based recommendations for the use of PN in LD. For this purpose three paradigm conditions of LD were chosen: alcoholic steatohepatitis (ASH), liver cirrhosis and acute liver failure. The guideline was developed by an interdisciplinary expert group in accordance with officially accepted standards and is based on all relevant publications since 1985. The guideline was presented on the ESPEN website and visitors' criticism and suggestions were welcome and included in the final revision. PN improves nutritional state and liver function in malnourished patients with ASH. PN is safe and improves mental state in patients with cirrhosis and severe HE. Perioperative (including liver transplantation) PN is safe and reduces the rate of complications. In acute liver failure PN is a safe second-line option to adequately feed patients in whom enteral nutrition is insufficient or impossible.

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

Abstract
Cirrhotic patients may become candidates for elective and emergency surgery. This may be due to conditions requiring operations such as cholecystectomy, herniotomy, or gastrointestinal malignancies, more common in cirrhotics when compared with the general population, or to complications of the liver disease such as resectable hepatocellular carcinomas or surgical portosystemic shunts to treat portal hypertension. It has been estimated that 10% of cirrhotics undergo at least one operative procedure during the final 2 y of their lives. Many studies have documented a high risk of morbidity and mortality associated with surgical procedures in these patients, and several factors influencing the postoperative outcome have been identified. Malnutrition, which is frequently encountered in cirrhotic patients, has been shown to have an important impact on the surgical risk. A poor nutrition status also has been associated with a higher risk of complications and mortality in patients undergoing liver transplantation. Few data are available concerning the perioperative nutrition support in surgical cirrhotic patients. The results of these studies are sometimes encouraging in reporting that the nutrition therapy may improve the clinical outcome in cirrhotic patients undergoing general surgery and/or liver transplantation. The limited number of patients and their heterogeneity, however, do not allow definitive conclusions, and more research on this issue is needed.

Abstract
Activated monocytes and macrophages have been postulated to play an important role in the pathogenesis of alcoholic liver disease (ALD). Monocyte activation can be documented by measurement of neopterin, adhesion cell molecules, and certain proinflammatory cytokines and chemokines. We first became interested in the role of monocytes and monocyte-derived cytokines in ALD in relation to altered zinc metabolism that occurs regularly in ALD. Patients with ALD have hypozincemia, which responds poorly to oral zinc supplementation. We have shown that in ALD monocytes make a low-molecular-weight substance that, when injected into rabbits, causes prominent hypozincemia. Subsequently, multiple cytokines [especially tumor necrosis factor (TNF) and interleukin (IL)-8] have been shown to be overproduced by monocytes in ALD. We initially showed that monocytes in ALD spontaneously produce TNF and overproduce TNF in response to a lipopolysaccharide (LPS) stimulus, and this could be attenuated by antioxidants in vitro and in vivo. Alterations in the endotoxin-binding protein LPS-binding protein, in CD14, and in the endotoxin receptor Toll-like receptor 4 all may play roles in enhanced proinflammatory cytokine signaling in ALD. Moreover, several groups have documented increased TNF receptor density in monocytes in ALD. Inadequate negative regulation of TNF occurs at multiple levels in ALD. This includes decreased monocyte production of the important antiinflammatory cytokine IL-10 and blunted response to the antiinflammatory properties of adenosine. Finally, generation of reactive oxygen species (which occurs during alcohol metabolism) and products of lipid peroxidation induce production of cytokines, such as TNF and IL-8. In conclusion, there are multiple overlapping potential mechanisms for enhanced proinflammatory cytokine production by monocytes in ALD. We postulate that activation of monocytes and macrophages with subsequent proinflammatory cytokine production plays an important role in certain metabolic complications of ALD and is a component of the liver injury of ALD.

Abstract
Malnutrition is common in severe liver disease. Assessment of malnutrition usually requires a subjective global assessment of the patient with a few additional tests that often include handgrip strength and arm-muscle circumference. The severity of liver disease correlates well with the severity of malnutrition, which has prognostic value. Malnutrition is multifactorial, is difficult to correct, and occurs in liver disease independently of the etiology of hepatic injury. Patients who have severe protein-calorie malnutrition require diets with high calorie and protein intake, even in the presence of hepatic encephalopathy. Some forms of complementary and alternative medicine are frequently used in patients with advanced liver disease, but supporting scientific data is needed. Obesity is detrimental to patients with advanced liver disease and is of greater concern in liver transplant candidates because it increases transplant-related morbidity. Data detailing the effects of aggressive nutritional support before transplantation are scarce, and more studies are needed.

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

Abstract
Measurements of resting energy expenditure (REE) can be used to determine energy requirements. Prediction formulae can be used to estimate REE but have not been validated in cirrhotic patients. REE was measured, by indirect calorimetry, in 100 cirrhotic patients and 41 comparable healthy volunteers, and the results compared with estimates predicted using the Harris-Benedict, Schofield, Mifflin, Cunningham, and Owen formulae, and the disease-specific Müller formula. The mean (+/- 1 SD) measured REE in the healthy volunteers (1,590 +/- 306 kcal/24 h) was significantly greater than the mean Harris-Benedict, Mifflin, Cunningham, and Owen predictions but comparable with the mean Schofield prediction; individual predicted values varied widely from measured values (95% limits of agreement, -460 to +424 kcal). The mean measured REE in the cirrhotic patients was significantly greater than in the healthy volunteers (23.2 +/- 3. 8 cf 21.9 +/- 2.9 kcal/kg/24 h; P <.05). The mean measured REE in the cirrhotic patients (1,660 +/- 337 kcal/24 h) was significantly different from mean predicted values (Harris-Benedict, 1,532 +/- 252 kcal/24 h, P <.0001; Schofield, 1,575 +/- 254 kcal/24 h, P <.0005; Mifflin, 1,460 +/- 254 kcal/24 h, P <.0001; Cunningham, 1,713 +/- 252 kcal/24 h, P <.05; Owen, 1,521 +/- 281 kcal/24 h, P <.0001; Müller, 1,783 +/- 204 kcal/24 h, P <.0001); individual predicted values varied widely from measured values (95% limits of agreement, -632 to +573 kcal). Simple regression analysis showed that fat-free mass (FFM) was the strongest predictor of measured REE in the cirrhotic patients, accounting for 52% of the variation observed. However, a population-specific prediction equation, derived using stepwise regression analysis, which incorporated FFM, age, and Pugh's score, accounted for only 61% of the observed variation in measured REE. REE should, therefore, be measured in cirrhotic patients, not predicted.

Abstract
BACKGROUND The liver plays a central role in ingestive behavior; alterations in metabolic signaling to the brain stem as a result of chronic liver disease could influence intake. OBJECTIVE We examined the influence of metabolic sequelae of liver disease on nutrient intake and nutritional status. DESIGN Nutritional status and spontaneous dietary intake were examined in 65 cirrhotic patients and 14 control subjects. The response to feeding was investigated in 14 control subjects and a subgroup of 31 cirrhotic patients. Comparisons were made between patients with primary biliary cirrhosis (PBC) and hepatocellular cirrhosis (HC). RESULTS Patients were nutritionally depleted. The fasting rate of lipid oxidation in the HC group was greater than in the control group (P < 0.01). In the fasting state, only HC patients were hyperinsulinemic [121.2+/-78.5 compared with 41.3+/-18.6 pmol/L in control subjects (P < 0.001) and 64.7+/-15.8 pmol/L in PBC patients (P < 0.05)] and this persisted during the response to feeding. In the fed state, the magnitude of change in carbohydrate oxidation was greatest in the HC group (HC: 34.6%; control: 23.1%; PBC: 25.2%). Carbohydrate and energy intakes of the HC group were lower than in control subjects (carbohydrate: 193+/-38.3 compared with 262+/-48.1 g/d, P < 0.05; energy: 6.29+/-1.40 compared with 9.0+/-2.12 MJ/d, P < 0.05). CONCLUSIONS Reductions in carbohydrate intake could be mediated by hyperinsulinemia and compounded by preferential uptake of carbohydrate. This may enhance gastrointestinal satiety signaling and contribute to hypophagia.

Abstract
Twenty-four-hour energy expenditure (EE) and substrate oxidation (respiratory chamber), and whole-body glucose uptake and oxidation rates (euglycemic hyperinsulinemic clamp [EHC] and indirect calorimetry) were measured in 10 male patients with posthepatitis, Child B cirrhosis, and 8 healthy male controls matched for age, body size, and body composition. Twenty-four-hour EE was higher in cirrhotic patients than in controls (8,567 +/- 764 vs. 6,825 +/- 507 kJ/d; P < .001). Resting energy expenditure (REE) was also higher in cirrhotic patients than in controls (7,881 +/- 1,125 vs. 5,868 +/- 489 kJ/d; P < .01). Twenty-four-hour respiratory quotient (RQ) (trend) and fasting RQ (0.76 +/- 0.05 vs. 0.82 +/- 0.04; P < .05) were lower in cirrhotic patients than in controls, reflecting higher lipid oxidation rates in the former group. Whole-body glucose uptake was markedly reduced in cirrhotic patients when compared with controls (22.4 +/- 3.2 vs. 44.5 +/- 7.6 mmol/kg/min; P < .001). Carbohydrate oxidation rates, computed during the last 40 minutes of the clamp, were 8.5 +/- 1.1 mmol/kg/min in cirrhotic patients and 22.6 +/- 6.1 mmol/kg/min in controls (P < .001). Nonoxidative glucose disposal was 13.9 +/- 2.5 mmol/kg/min in cirrhotic patients and 22.0 +/- 5.5 mmol/kg/min in normal controls (P < .01). In conclusion, our data indicate that patients with Child B cirrhosis who still maintain a nutritional status (i.e., body composition) comparable with healthy controls are characterized by a cluster of metabolic defects that include hypermetabolism, increased lipid utilization, and insulin resistance. This suggests that the above metabolic syndrome precedes and probably leads to malnutrition in the natural history of the liver disease. In fact, in spite of the absence of a significant difference in caloric intake between cirrhotic patients and normal controls, the elevated 24-hour EE might allow for a relevant weight loss in cirrhotic patients, because, with time, the differences may be cumulative. However, whether this hypermetabolism can lead to a real weight loss remains to be evaluated in a longitudinal study.

Abstract
BACKGROUND/AIMS In order to ascertain whether malnutrition is an early-onset feature of liver cirrhosis and whether the anabolic hormone insulin-like growth factor I (IGF-I) could be useful in the treatment of this complication, we analyzed the nutritional alterations present in rats with early-stage liver cirrhosis and the effects of IGF-I on nutritional parameters in these animals. METHODS After a 24 h fast, a 15N-enriched diet was administered for 5 days to normal control rats and to cirrhotic rats receiving subcutaneous injections of vehicle (Group 1) or IGF-I, 2 micrograms.100 g bw-1.day-1, (Group 2) during the 5 experimental days. 15N, a stable N isotope, was measured in biological samples by mass spectrometry. RESULTS Compared with control rats, Group 1 animals showed significant reductions in N intake and food efficiency (p < 0.05, both). In addition, the weight of the gastrocnemius muscle, its total N content and the dietary N content of this muscle were significantly lower in Group 1 than in control animals (p < 0.05, all). In rats from Group 2, mean values of N intake, food efficiency, gastrocnemius N content and the amount of dietary N incorporated into this muscle were similar to those in control rats, and (with the exception of gastrocnemius N total content) significantly higher than those in non-treated cirrhotic rats (p < 0.05, all). CONCLUSIONS A variety of nutritional disturbances were detected in rats from the early stages of liver cirrhosis. Low doses of IGF-I were found to reverse most of these changes. These results stimulate further studies to determine whether IGF-I might be useful in the correction of the malnutrition present in patients with liver cirrhosis.

Abstract
Energy expenditure was investigated in 15 patients with liver cirrhosis and 20 healthy controls by three methods: indirect calorimetry, anthropometry using the Harris-Benedict equation and bioelectrical impedance analysis. The energy expenditure was expressed in kcal/day, kcal/kg BW/day (BW - body weight), kcal/kg LBM/day (LBM - lean body mass, derived by bioelectrical impedance analysis) or in kcal/m2/day. We did not find statistical differences between values of resting energy expenditure obtained in patients with cirrhosis of the liver and healthy controls whichever method we used. We also did not find statistical differences between values obtained by indirect calorimetry, anthropometry and bioelectrical impedance analysis. There was a significant correlation between indirect calorimetry and anthropometry in both groups. We found significant correlations between indirect calorimetry and anthropometry, and between indirect calorimetry and bioelectrical impedance analysis, in the control group only. We can conclude that (1) resting energy expenditure of patients with cirrhosis of the liver is not changed when compared with healthy controls, and (2) bioelectrical impedance is a useful method to calculate body composition from which energy expenditure is derived; however, it gives an appropriate result only in healthy people, and only approximate values in patients with cirrhosis.

Abstract
BACKGROUND Active nutrition therapy and the anabolic steroid oxandrolone (OX), in selected patients with severe alcoholic hepatitis, significantly improved liver status and survival. We report here on the changes in their nutritional parameters. METHODS Protein energy malnutrition (PEM) was evaluated and expressed as percent of low normal in 271 patients initially, at 1 month and at 3 months. Active therapy consisted of OX plus a high caloric food supplement vs a matching placebo and a low calorie supplement. RESULTS PEM was present in every patient; mean PEM score 60% of low normal. Most of the parameters improved significantly from baseline on standard care; the largest improvement seen in visceral proteins, the smallest in fat stores (skinfold thickness). Total PEM score significantly correlated with 6 month mortality (p = .0012). Using logistic regression analysis, creatinine height index, hand grip strength and total peripheral blood lymphocytes were the best risk factors for survival. When CD lymphocyte subsets replaced total lymphocyte counts in the equation, CD8 levels became a significant risk factor (p = .004). Active treatment produced significant risk factor (p = .004). Active treatment produced significant improvements in those parameters related to total body and muscle mass (ie, mid arm muscle area, p = .02; creatinine height index, p = .03; percent ideal body weight, p = .04). CONCLUSION Deterioration in nutritional parameters is a significant risk factor for survival in severe patients with alcoholic hepatitis. This deterioration is reversible with standard hospital care. Active therapy further improves creatinine height index, mid arm muscle area and total lymphocyte counts. Hence, these later parameters appear to be the best indicators for follow-up assessments.

Abstract
Malnutrition in patients with liver cirrhosis is currently associated with abnormal fuel metabolism. The aim of this study was to evaluate changes in energy production and substrate oxidation rates in a group of 26 nonanorectic severely malnourished cirrhotic patients in stable clinical condition after 1 month of an oral diet. Child-Pugh score, nutritional status, energy expenditure, rates of nutrient oxidation, and plasma levels of intermediary metabolites in the postabsorptive phase were assessed before and after 1 month of oral nutrition. Upon entry onto the study, caloric and protein intakes were 40.1 +/- 2.0 kcal/kg and 1.44 +/- 0.8 g/kg, respectively. The Child-Pugh score did not change during the study, whereas nutritional status improved as shown by increased muscular midarm circumference, ([MMAC] P < .02), height-creatinine index (P < .05), triceps skinfold thickness ([TST] P < .01), and fat mass (P < .001). Inflammatory state improved during the study, as shown by the decrease of C-reactive protein ([CRP] P < .01) and orosomucoid (P < .001). The ratio of caloric intake to resting energy expenditure (REE) increased (1.53 +/- 0.06 v 1.66 +/- 0.07, P < .05), as well as the rate of glucose oxidation ([Gox] 73.6 +/- 9.9 v 128.1 +/- 10.3 mg/min, P < .001) and urine nitrogen excretion (6.69 +/- 0.47 v 7.96 +/- 0.48 g/d, P < .02). On the other hand, the rate of lipid oxidation (Lox) decreased (67.3 +/- 3.9 v 47.3 +/- 4.9 mg/min, P < .001) and was correlated with the decrease of free fatty acid (FFA) levels (P < .05).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
The relationship of protein calorie malnutrition (PCM) to alcoholic liver disease was studied in 666 patients enrolled in two Veterans Administration Cooperative Studies. Some findings of malnutrition could be detected early in 62% of the comparison patients (43 subjects who were alcoholic, but had not yet developed clinical or laboratory evidence of liver injury). In those who had progressed to the stage of liver injury sufficient to manifest clinical jaundice (536 patients), some findings of malnutrition were present in every patient (100%). The degree of malnutrition correlated closely with the development of all the serious complications of the liver disease (ascites, encephalopathy, and hepatorenal syndrome), as well as the overall mortality. The degree of malnutrition was also important in predicting response to some forms of treatment. When prednisolone, a catabolic adrenal steroid, was used, efficacy was independent of the level of malnutrition. However, a relationship was observed with the severity of the liver injury [quantified by the level of jaundice and coagulopathy, i.e., Maddrey's discriminant function (DF(Maddrey)]. For prednisolone, the response was seen only when the DF was 81-100 reducing mortality 45% When oxandrolone, an androgenic anabolic steroid treatment was given, efficacy was observed only in those with moderate malnutrition (PCM score 60-79% of normal) and maximized with adequate caloric intake reducing mortality 86%. To simplify the method of calculating the PCM score for predicting response to anabolic therapy, a multiple logistic regression model was developed from the parameters used to assess nutritional status: DF(PCM) = 0.098 (peripheral blood lymphocytes) + 0.078 (creatinine height index).(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
OBJECTIVE This study was designed to measure the effect of chronic alcohol intake on leucine turnover in outpatients with stable alcoholic liver cirrhosis. METHODS Protein turnover rate was measured using L [1-14C] leucine in ten outpatients with proven alcoholic cirrhosis and in five healthy controls. After the performance of the turnover, the patients were divided in two groups depending on the evidence of alcohol ingestion in the previous month. RESULTS Non-abstinent patients had a significantly higher leucine flux and non-oxidative disposal (73.8 +/- 25.4 and 65.9 +/- 21.6) than abstinent cirrhotic patients (48.9 +/- 9.5 and 43.7 +/- 9.0) and normal controls 37.3 +/- 8.9 and 31.1 +/- 7.6 mumol/m2/min (p < 0.01). Leucine oxidation and serum leucine levels were similar in the three groups. CONCLUSION Alcohol intake in alcoholic cirrhotic patients has a catabolic effect that could be associated with the nutritional imbalances observed in alcoholic liver disease.

Abstract
A Veterans Affairs cooperative study involving 273 male patients was performed to evaluate efficacy of oxandrolone in combination with an enteral food supplement in severe alcoholic hepatitis. All patients had some degree of protein calorie malnutrition. On an intention-to-treat basis, only minimal changes in mortality were observed. However, in patients with moderate malnutrition mortality on active treatment at 1 mo was 9.4% compared with 20.9% in patients receiving placebo. This beneficial effect was maintained so that after 6 mo on active treatment 79.7% of patients were still alive, compared with 62.7% of placebo-treated patients (p = 0.037). Improvements in both the severity of the liver injury (p = 0.03) and malnutrition (p = 0.05) also occurred. No significant improvement was observed with severe malnutrition. To better determine the effect on therapeutic efficacy, we compared results with those from a nearly identical population (cooperative study 119) treated with oxandrolone but not given the food supplement. Patients were stratified according to their caloric intake (greater than 2,500 kcal/day was considered adequate to supply energy needs and promote anabolism). For patients with moderate malnutrition and adequate caloric intake, oxandrolone treatment reduced 6-mo mortality (4% active treatment vs. 28% placebo [p = 0.002]). For patients with moderate malnutrition and inadequate calorie intake, oxandrolone had no effect on mortality (30% active treatment vs. 33% placebo). In cases of severe malnutrition, oxandrolone had no effect on survival. However, adequate caloric intake was associated with 19% mortality, whereas patients with inadequate intake exhibited 51% mortality (p = 0.0001). These results indicate that nutritional status should be evaluated in patients with alcoholic hepatitis. When malnutrition is present, vigorous nutrition therapy should be provided, and in patients with moderate malnutrition oxandrolone should be added to the regimen.

Abstract
The biochemistry of alcohol liver disease as it relates to clinical medicine and experimental alcohol liver disease is presented. Clinical features are emphasized in the diagnosis of alcohol liver disease, particularly as it relates to staging the disease and predictors of prognosis. Currently, it is true that the biochemical diagnosis of alcohol liver disease is at best very limited in terms of the sensitivity tests and specificity of the test. It is particularly difficult to detect alcohol liver disease biochemically in the early stages when steatohepatitis is not severe. Consequently, 50% of the patients have already developed cirrhosis at the time they are diagnosed clinically. In this review indicators of malnutrition are emphasized because they have the strongest implications regarding survival during the acute hospitalization stage of the disease. They are also the best indicators of response to therapy during the recovery phase. With respect to experimental work on the pathogenesis of alcohol liver disease, it appears that necrosis is due to the inability to increase blood flow to compensate for increased oxygen utilization. The hypothesis that mitochondrial damage is the cause of liver cell damage is regarded as less important in the pathogenesis of necrosis. The shift in the redox state during alcohol metabolism accounts for the fatty change noted in the central lobular area of the liver in animals fed alcohol. Apparently, there is strong experimental evidence that highly reactive intermediates are important in the pathogenesis of liver damage due to the induction of the isozyme cytochrome P450 IIE1 by alcohol ingestion. This mechanism is enhanced by a diet high in polyunsaturated fatty acids.

Abstract
Using H2[18O] tracer isotope dilution and corrected bromide space as standard reference techniques, we determined total body water and extracellular water in cirrhotic patients with (four men and four women) and without (seven men and six women) ascites and compared them with a normal control group (eight men and six women). These results were then compared with calculations of total body and extracellular water determined by the bioelectrical impedance analysis technique. According to H2[18(O)] dilution, total body water was similar in cirrhotic patients without ascites and in controls (60.8% +/- 2.1% vs. 60.3% +/- 1.4% body wt), but was increased in patients with ascites (69.7% +/- 1.2% body wt; p less than 0.002). Correlation was excellent between the H2[18(O)] dilution and bioelectrical impedance measurements of total body water in controls and cirrhotic patients without ascites (r = 0.98; p less than 0.0001). However, this correlation was poor in cirrhotic patients with ascites (r = 0.17; not significant). According to the bromide space, extracellular water (expressed as a percentage of total body water) was increased in cirrhotic patients with (57.8% +/- 1.8%; p less than 0.001) and without (44.0% +/- 1.2%; p less than 0.001) ascites compared with controls (36.6% +/- 1.0%). A poor correlation (r = 0.41; p less than 0.13) was seen for extracellular water measurements between the bromide space method and the bioelectrical impedance method, which failed to detect the differences among the three groups observed with the bromide space technique. Furthermore, bioelectrical impedance failed to detect any change in total body or extracellular water after paracentesis, with a degree of inaccuracy that increased linearly as the amount of ascitic fluid removed increased (r = 0.97; p less than 0.001). All these intergroup comparisons remained the same, whether the analysis was of both men and women combined or for each gender individually. However, we saw differences between men and women in the control group and cirrhotic group without ascites. These results demonstrate that abnormalities in water homeostasis and compartmentalization between intracellular (the difference between total body and extracellular water fluid) and extracellular water may exist in cirrhosis whether or not fluid accumulation is clinically evident. These data further indicate that alterations in the metabolically active body cell mass (as represented by intracellular water) in cirrhosis may occur independently of total body water and calculated fat-free body mass. In addition, gender is an important variable to control for in studies of this type.(ABSTRACT TRUNCATED AT 400 WORDS)

Abstract
While the rate of malnutrition is relatively modest in alcoholic patients without alcoholic liver disease, the rate of malnutrition is virtually 100% in patients with alcoholic hepatitis and/or alcoholic cirrhosis. The reasons for malnutrition in the alcoholic hepatitis patient include various factors such as anorexia, poor diet, malabsorption, and altered metabolic state. When the patient is hospitalized, the malnutrition frequently worsens because of fasting for tests, continued anorexia, and complications such as gastrointestinal bleeding. Patients with severe acute hepatitis appear to be both hypermetabolic and hypercatabolic, whereas data are much more conflicting concerning patients with more stable liver disease. Most studies suggest that patients with alcoholic liver disease require at least 60 g of protein per day to maintain positive nitrogen balance. Consistent alterations in plasma amino acid profiles occur in alcoholic liver disease, and specialized nutritional formulations have been devised to correct this amino acid profile with the intent of improving overall nutritional status, hepatic encephalopathy, and mortality. The effects of nutritional support (including use of specialized products) on outcome, on acute hepatic encephalopathy, and on chronic or latent portal systemic encephalopathy are reviewed.

Abstract
The basal energy production rate was measured using indirect calorimetry in 25 stable cirrhotic patients and 10 controls of comparable age. The endogenous substrate oxidation was also calculated by measuring urinary nitrogen excretion. The energy production rate was similar in cirrhotic patients and controls. The origins of liver disease and the degree of liver damage did not seem to influence the energy production rate. On the other hand, in cirrhotic patients, as in controls, a significant correlation was present between the energy production rate and parameters of body size, such as body weight and fat-free mass. As a consequence, cirrhotic patients with poor nutritional status, with a reduced fat-free mass, showed a lower energy production rate. The measured energy production rate was compared with the resting energy expenditure estimated by formulas commonly used in healthy individuals. The good agreement found between the measured energy production rate and calculated energy expenditure suggests that these formulas may be applied to stable cirrhotic patients in clinical practice. In cirrhotic patients, the oxidation of endogenous fat is the main contributor to basal energy production rate. The fat oxidation rate does not appear to be influenced by the hormonal pattern found in the cirrhotic patients. However, a significant correlation was present between fat oxidation and plasma free fatty acid levels. This confirms that the prevalent fat use in cirrhotic patients is supported by the greater availability of fat-derived substrates.
