Evaluation and Management of Nutritional Consequences of Chronic Liver Diseases. Nutrients 2023; 15:3487. [PMID: 37571424 PMCID: PMC10421025 DOI: 10.3390/nu15153487] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2023] [Revised: 08/03/2023] [Accepted: 08/04/2023] [Indexed: 08/13/2023] Open
Abstract
Liver diseases are the major predisposing conditions for the development of malnutrition, sarcopenia, and frailty. Recently, the mechanism of the onset of these complications has been better established. Regardless of the etiology of the underlying liver disease, the clinical manifestations are common. The main consequences are impaired dietary intake, altered macro- and micronutrient metabolism, energy metabolism disturbances, an increase in energy expenditure, nutrient malabsorption, sarcopenia, frailty, and osteopathy. These complications have direct effects on clinical outcomes, survival, and quality of life. The nutritional status should be assessed systematically and periodically during follow-up in these patients. Maintaining and preserving an adequate nutritional status is crucial and should be a mainstay of treatment. Although general nutritional interventions have been established, special considerations are needed in specific settings such as decompensated cirrhosis, alcohol-related liver disease, and metabolic-dysfunction-associated fatty liver disease. In this review, we summarize the physiopathology and factors that impact the nutritional status of liver disease. We review how to assess malnutrition and sarcopenia and how to prevent and manage these complications in this setting.

Measurement of mid-arm circumference as a starting point for nutritional assessment of patients with decompensated cirrhosis: A prospective cohort study. J Hum Nutr Diet 2023; 36:116-125. [PMID: 35822512 DOI: 10.1111/jhn.13067] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2022] [Accepted: 06/27/2022] [Indexed: 01/19/2023]
Abstract
BACKGROUND The mid-arm circumference (MAC) is an accessible, quick, and inexpensive measurement, which can be performed at the bedside only with a measuring tape. In this sense, the present study aims to suggest MAC cut-off values to assess the nutritional status and its association with mortality of hospitalised patients with decompensated cirrhosis. METHODS A prospective cohort study was performed with decompensated cirrhotic patients. Nutritional status was assessed by MAC and Subjective Global Assessment (SGA). Considering the SGA as the reference standard and based on receiver operating characteristic curve analysis, the MAC cut-off values with the best sensitivity and specificity were selected. Predictors of mortality were identified using multivariate analysis. RESULTS The study included 100 patients with a mean ± SD age of 60.1 ± 10.3 years. The median follow-up time was 11.2 months and overall mortality was 60%. Considering malnutrition assessed by SGA as the reference standard, the area under the curve of MAC for women and men was 0.947 (95% confidence interval [CI] = 0.878-1.000) and 0.813 (95% CI = 0.694-0.932). The MAC cut-off values of ≤ 28 cm for women and ≤ 30 cm for men reached a sensitivity and specificity of 85.5% and 71%, respectively. According to multivariate analysis, a low MAC was significantly associated with mortality (hazard ratio = 2.41; 95% CI = 1.20-4.84). CONCLUSIONS The MAC cut-off values had satisfactory accuracy for men and women in predicting malnutrition. Additionally, a low MAC was an independent predictor of mortality. Thus, these MAC cut-off values can be used as the first step of nutritional assessment to prioritise patients who require more detailed assessment.

Role of Branched-Chain Amino Acids and Their Derivative β-Hydroxy-β-Methylbutyrate in Liver Cirrhosis. J Clin Med 2022; 11:jcm11247337. [PMID: 36555953 PMCID: PMC9780785 DOI: 10.3390/jcm11247337] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/08/2022] [Revised: 11/24/2022] [Accepted: 12/08/2022] [Indexed: 12/14/2022] Open
Abstract
Branched-chain amino acids (BCAA) supplementation is used to promote protein synthesis in different clinical conditions in which proteolysis is increased. In addition, lower plasma BCAA levels have been related to an increased risk of hepatic encephalopathy in liver cirrhosis. In this article we will review the role of supplementation with BCAAs and BCAA derivative β-hydroxy-β-methylbutyrate (HMB) in liver cirrhosis, focusing on nutritional and clinical effects. Evidence shows that BCAA supplementation slightly increases muscle mass and body mass index, with an upward trend in muscular strength and no change in fat mass. Moreover, BCAA supplementation improves symptoms of hepatic encephalopathy, and is indicated as second-line therapy. The evidence is more limited for BCAA derivatives. HMB supplementation appears to increase muscle mass in chronic diseases associated with cachexia, although this effect has not yet been clearly demonstrated in liver cirrhosis studies. To date, HMB supplementation has no clinical indication in liver cirrhosis.

Impact of sarcopenia on post-liver transplant morbidity and mortality in cirrhotic patients. Indian J Gastroenterol 2022; 41:440-445. [PMID: 36342633 DOI: 10.1007/s12664-022-01262-3] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/17/2021] [Accepted: 05/01/2022] [Indexed: 11/09/2022]
Abstract
BACKGROUND Modalities available for severity assessment and prediction of complications after liver transplant (LT) in cirrhotic patients are model for end-stage liver disease-sodium (MELD-Na) and Child-Turcotte-Pugh (CTP) scores. The limitation of these scores is the lack of assessment of nutritional and functional status. Sarcopenia is a newer modality, which is developed for objective assessment of nutritional status. The aim of this study is to analyze the significance of sarcopenia in predicting 1-year mortality and morbidity in post-LT patients. METHODS In this retrospective study, patients who underwent LT for cirrhosis between January 2013 and December 2018 were included. A computerized tomography (CT) image was used to analyze the psoas muscle index at the L3 vertebra (L3-PMI), and sarcopenia was defined as the values belonging to the lowest quartile of L3-PMI. The effect of sarcopenia on mortality and morbidity in terms of requirement for mechanical ventilation, duration of hospital stay, and occurrence of infections was studied. RESULTS Among the study population (n = 74), 71 were men and the mean age was 51 years. Sarcopenia was observed in 27% (n = 20). Fifteen recipients had mortality within 1 year after transplant. In our analysis, sarcopenia was significantly associated with 1-year mortality (sensitivity 60%, specificity 81%; positive predictive value [PPV] 45%; negative predictive value [NPV] 88%; and p-value 0.001). Duration of mechanical ventilation, total hospital stay, and occurrence of infection were not significantly associated with sarcopenia. Sarcopenia was found as an independent predictor of mortality on binary logistic regression. CONCLUSION The preoperative sarcopenia index in cirrhotic patients can predict the risk of mortality in post-liver transplant patients.

Randomized Clinical Trial: Effects of β-Hydroxy-β-Methylbutyrate (HMB)-Enriched vs. HMB-Free Oral Nutritional Supplementation in Malnourished Cirrhotic Patients. Nutrients 2022; 14:nu14112344. [PMID: 35684144 PMCID: PMC9183090 DOI: 10.3390/nu14112344] [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: 05/03/2022] [Revised: 05/27/2022] [Accepted: 05/31/2022] [Indexed: 11/17/2022] Open
Abstract
β-Hydroxy-β-methylbutyrate (HMB) supplementation increases muscle and strength mass in some muscle-wasting disorders. Malnutrition and sarcopenia are often present in liver cirrhosis. We aimed to investigate the effects of oral HMB supplementation on changes in body composition and liver status in patients with cirrhosis and malnutrition. In a randomized, controlled, double-blind trial, 43 individuals were randomized to receive twice a day and for 12 weeks an oral nutritional supplement (ONS) enriched with 1.5 g of calcium HMB per bottle or another supplement with similar composition devoid of HMB. Inclusion criteria were liver cirrhosis with at least one previous decompensation and clinical malnutrition. Liver function, plasma biochemistry analyses, and physical condition assessment were carried out at baseline, then after six and 12 weeks of supplementation. A total of 34 patients completed the clinical trial. An improvement in liver function and an increase in fat mass index were observed in both groups. None of the two ONS changed the fat-free mass. However, we observed an upward trend in handgrip strength and a downward trend in minimal hepatic encephalopathy in the HMB group. At the end of the trial and regardless of the supplement administered, fat mass content increased with no change in fat-free mass, while liver function scores and nutritional analytic markers also improved.

Abstract
Malnutrition among patients with chronic liver disease (CLD) is a common complication with significant prognostic implications for patients with liver cirrhosis. Micronutrient deficiency has been associated with an increased risk of hepatic decompensation and is an independent risk factor for mortality among cirrhotic patients. Micronutrient deficiencies in patients with CLD include zinc, vitamin A, vitamin D and selenium. This review article aims to evaluate the literature to date on the complications of zinc deficiency in patients with CLD. A management algorithm for zinc replacement has also been proposed.

Abstract
Aim Malnutrition is common in cirrhotic patients; however, there is no gold standard for nutritional assessment for this population. The aim of this study was to develop a novel nutritional screening tool based on objective indicators for cirrhotic patients chronically infected with hepatitis B virus (HBV). Methods This was a cross-sectional study. Patients with hepatitis B-related cirrhosis were recruited. Malnutrition was diagnosed by the presence of any of the following conditions: Nutrition Risk Screening 2002 score greater than 3 points, Subjective Global Assessment grade B or C, and body mass index (BMI) <18.5 kg/m2. Nomogram model and decision tree model were developed, and the area under the receiver operating characteristic curve (AUROC) was compared. Results Among the 231 studied cases, 92 (39%) were malnourished. Malnourished patients had significantly lower serum albumin, BMI and hand grip strength levels, but higher serum creatinine level and Child-Pugh grade. Two models were developed based on these variables. The nomogram model had a sensitivity of 0.696, a specificity of 0.820 and an accuracy of 0.813. The AUROC of nomogram model was 0.813 (95% CI: 0.758-0.869, p <0.001). For the decision tree model, the sensitivity, specificity and accuracy are 0.761, 0.885 and 0.886, respectively, with an AUROC of 0.886 (95% CI: 0842-0.930, p <0.001). The difference in AUROC between these two models was not statistically significant (p <0.001). Conclusion The nomogram model and decision tree model developed in this study may aid assessing nutritional status for cirrhotic patients with HBV.

Abstract
INTRODUCTION Metabolic and hormonal disorders resulting from chronic liver diseases culminate in increased proteolysis and decreased protein synthesis, which contributes to the development and progression of malnutrition and, consequently, sarcopenia. Nutritional management of sarcopenia in liver cirrhosis is a continuously evolving field and data on essential amino acid supplementation in chronic liver diseases is scarce. AREAS COVERED This review encompasses the current literature on oral amino acids supplementation in patients with chronic liver disease or patients with liver cirrhosis to try to elucidate the possible effects of L-branched-chain amino acids and isolated L-leucine as a therapeutic approach to malnutrition and sarcopenia. EXPERT COMMENTARY To ensure an optimal nutritional status and to reduce sarcopenia, it is necessary to assess nutritional status in all patients with liver cirrhosis and to apply nutritional interventions accordingly. The supply of calories, proteins, and essential amino acids is necessary for the maintenance of muscle mass and function. Although supplementation of L-branched-chain amino acids plays an important role in liver disease, L-leucine has been described as the main amino acid involved in protein turnover, reducing proteolysis, and stimulating protein synthesis.

Abstract
OBJECTIVES The use of easily accessible methods to estimate skeletal muscle mass (SMM) in patients with cirrhosis is often limited by the presence of edema and ascites, precluding a reliable diagnosis of sarcopenia. The aim of this study was to design predictive models using variables derived from anthropometric and/or biochemical measures to estimate SMM; and to validate their applicability in diagnosing sarcopenia in patients with cirrhosis. METHODS Anthropometric and biochemical data were obtained from 124 male patients (18-76 y of age) with cirrhosis who also underwent dual-energy x-ray absorptiometry (DXA) and handgrip strength (HGS) assessments to identify low SMM and diagnose sarcopenia using reference cutoff values. Univariate analyses for variable selection were applied to generate predictive decision tree models for low SMM. Model accuracy for the prediction of low SMM and sarcopenia (when associated with HGS) was tested by comparison with reference cutoff values (appendicular SMM index, obtained by DXA) and clinical sarcopenia diagnoses. The prognostic value of the models for the prediction of sarcopenia and mortality at 104 wk of follow up was further tested using Kaplan-Meier graphics and Cox models. RESULTS The models with anthropometric variables, alone and combined with biochemical variables, showed good accuracy (0.89 [0.83; 0.94] and 0.90 [0.84; 0.95], respectively) and sensitivity (0.72 [0.56; 0.85] and 0.74 [0.59; 0.86], respectively) and excellent specificity (0.96 [0.90; 0.99] and 0.97 [0.92; 0.99], respectively) in predicting SMM. Both models showed excellent accuracy (0.94 [0.89; 0.98], good sensitivity (0.68 [0.45; 0.86]), and excellent specificity (1.00 [0.96; 1.00]) in predicting sarcopenia. The models predicted mortality in patients with sarcopenia, with the likelihood of death sixfold greater relative to patients not predicted to have sarcopenia. CONCLUSIONS Our simple and inexpensive models provided a practical and safe approach to diagnosing sarcopenia patients with cirrhosis along with an estimate of their mortality risk when other reference methods are unavailable.

Royal Free Hospital-Nutritional Prioritizing Tool improves the prediction of malnutrition risk outcomes in liver cirrhosis patients compared with Nutritional Risk Screening 2002. Br J Nutr 2020; 124:1293-1302.

Abstract
The European Society for Clinical Nutrition and Metabolism (ESPEN) guidelines recommend the Royal Free Hospital-Nutritional Prioritizing Tool (RFH-NPT) to identify malnutrition risk in patients with liver disease. However, little is known about the application of the RFH-NPT to screen for the risk of malnutrition in China, where patients primarily suffer from hepatitis virus-related cirrhosis. A total of 155 cirrhosis patients without liver cancer or uncontrolled co-morbid illness were enrolled in this prospective study. We administered the Nutritional Risk Screening 2002 (NRS-2002), RFH-NPT, Malnutrition Universal Screening Tool (MUST) and Liver Disease Undernutrition Screening Tool (LDUST) to the patients within 24 h after admission and performed follow-up observations for 1·5 years. The RFH-NPT and NRS-2002 had higher sensitivities (64·8 and 52·4 %) and specificities (60 and 70 %) than the other tools with regard to screening for malnutrition risk in cirrhotic patients. The prevalence of nutritional risk was higher under the use of the RFH-NPT against the NRS-2002 (63 v. 51 %). The RFH-NPT tended more easily to detect malnutrition risk in patients with advanced Child–Pugh classes (B and C) and lower Model for End-stage Liver Disease scores (<15) compared with NRS-2002. RFH-NPT score was an independent predictive factor for mortality. Patients identified as being at high malnutrition risk with the RFH-NPT had a higher mortality rate than those at low risk; the same result was not obtained with the NRS-2002. Therefore, we suggest that using the RFH-NPT improves the ability of clinicians to predict malnutrition risk in patients with cirrhosis primarily caused by hepatitis virus infection at an earlier stage.

Abstract
The obesity epidemic has resulted in an increased prevalence of obesity in liver transplant (LT) candidates and in non-alcoholic fatty liver disease (NAFLD) becoming the fastest growing indication for LT. LT teams will be dealing with obesity in the coming years, and it is necessary for them to recognize some key aspects surrounding the LT in obese patients. Obesity by itself should not be considered a contraindication for LT, but it should make LT teams pay special attention to cardiovascular risk assessment, in order to properly select candidates for LT. Obese patients may be at increased risk of perioperative respiratory and infectious complications, and it is necessary to establish preventive strategies. Data on patient and graft survival after LT are controversial and scarce, especially for long-term outcomes, but morbid obesity may adversely affect these outcomes, particularly in NAFLD. The backbone of obesity treatment should be diet and exercise, whilst being careful not to precipitate or worsen frailty and sarcopenia. Bariatric surgery is an alternative for treatment of obesity, and the ideal timing regarding LT is still unknown. Sleeve gastrectomy is probably the procedure that has the best evidence in LT because it offers a good balance between safety and efficacy.

Abstract
BACKGROUND & AIMS The objective nutritional assessment indicators, body mass index (BMI), upper arm muscle circumference (MAMC), and triceps skinfold thickness (TSF), are often limited due to ascites. This study investigated the prognostic value of the third lumbar vertebrae skeletal muscle mass index (L3 SMI) in addition to the objective nutritional evaluation indicators (BMI, MAMC and TSF) in patients with liver cirrhosis and ascites. METHODS In this retrospective analysis, a total of 147 patients with liver cirrhosis and ascites were included. The L3 SMI, BMI, MAMC and TSF were detected in all patients. The severity of liver disease was assessed by the Model End-Stage Liver Disease (MELD) score and Child-Turcotte-Pugh (CTP) classification. These variables were compared between non-surviving and surviving patients who were classified according to 5-year mortality. RESULTS Of the 147 patients, 62 (42.2%) died and 85 (57.8%) survived within 5 years. The L3 SMI of patients was significantly lower than that of the normal control group (39.58 ± 7.18 cm2/m2 vs. 53.73 ± 7.92 cm2/m,2p < 0.001). The L3 SMI (OR 4.02; 95% CI 2.17-9.63; p < 0.001), MELD score (OR 2.11; 95% CI 1.12-4.13; p < 0.001) and CTP class (OR 2.69; 95% CI 1.09-5.06; p < 0.001) were independent predictive indicators of 5-year mortality. Furthermore, the performance of the two variables (L3 SMI and MELD) together (AUROC: 0.812) was significantly better than that of MELD alone (AUROC: 0.787) for prediction of 5-year mortality (p < 0.001). CONCLUSION Compared with MAMC, TSF and BMI, L3 SMI is an independent risk factor for 5-year mortality in patients with liver cirrhosis and ascites. Further nutritional intervention studies are needed to confirm the impact of the L3 SMI index on clinical outcomes.

Abstract
OBJECTIVE The aim was to assess the relationship between muscle mass depletion and chronic hepatitis C virus (HCV) infection. PATIENTS AND METHODS We retrospectively evaluated abdominal computed tomography data for 611 patients. The participants included 302 patients with HCV infection and 309 patients with gallstones (as a control). The skeletal muscle mass at the level of the third lumber vertebra (L3) was measured from the computed tomography images and normalized for height to calculate the L3 skeletal muscle index (L3-SMI, cm/m). Statistical analysis was carried out separately for each sex, given that L3-SMI differs significantly between men and women. RESULTS L3-SMI showed no significant difference between chronic hepatitis patients and gallstone patients in either sex. L3-SMI was significantly lower in male cirrhotic patients than in those with chronic hepatitis (P<0.001). The Child-Pugh score was correlated negatively with L3-SMI in male patients with HCV-related cirrhosis (ρ=0.200, P=0.031). In addition, the BMI in both sexes was associated with L3-SMI in the gallstone and chronic hepatitis group, in the chronic hepatitis and liver cirrhosis group, and in the liver cirrhosis group. CONCLUSION Skeletal muscle mass is not affected by chronic HCV infection in patients without cirrhosis and decreases in accordance with liver disease progression in male patients with chronic HCV infection.

Abstract
Hepatic encephalopathy is a neuropsychological syndrome due to biochemical disturbance of brain function in advanced liver disease patients. Diagnosis and treatment of the condition is very demanding and has negative toll on finances with increased healthcare utilization. The pathophysiology is not completely understood; however, there is evidence that ammonia plays an important role in the etiology. Conventional methods of solely relying on blood ammonia level to diagnose hepatic encephalopathy did not help much; likewise, the use of lactulose alone in treating hepatic encephalopathy has also been discouraged. This paper analyzed the current knowledge regarding the mechanism of how ammonia disrupts the normal brain function as well as the use of latest diagnosing tools including those under development to evaluate the neuropsychiatric state of patients and their quality of life. The efficacies of lactulose and rifaximin combination for short-term and long-term treatment in addition to nutritional interventions and other drugs undergoing clinical trials were also reviewed.

Vitamin C Status in Hospitalized Adults According to Subjective Global Assessment Method. JPEN J Parenter Enteral Nutr 2018; 43:789-793. [PMID: 30350314 DOI: 10.1002/jpen.1460] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/18/2018] [Accepted: 09/18/2018] [Indexed: 12/28/2022]
Abstract
BACKGROUND The subjective global assessment (SGA) is a powerful tool for nutrition status assessment. Our aim was to compare vitamin C serum levels among patients classified as A, B, or C in the SGA. METHODS One hundred-and-fifty adults in the wards of the University Hospital participated in this study. Besides SGA, all cases were submitted to anthropometry, bioelectrical impedance analysis (BIA), and 24-hour dietary recall. Laboratory data included blood hemoglobin, serum ferritin, serum albumin, transferrin, C-reactive protein (CRP), and vitamin C. Acute phase response was defined by serum CRP > 0.5 mg/dL; low serum vitamin C was defined by serum levels < 0.4 mg/dL. Analysis of variance and χ2 tests were used to compare groups; P < 0.05 was considered significant. RESULTS Patients were diagnosed as SGA A (n = 76), B (n = 38), or C (n = 36) and showed different anthropometry and BIA. The same occurred, respectively, with vitamin C (median; range, in mg/day) intake (55.0; 4.7-140.6 vs 34.0; 10.3-244.2 vs 15.8; 2.3-124.0) and high (%) CRP (88.3 vs 65.8 vs 48.7) and low (%) vitamin C serum levels (21.1 vs 34.2 vs 63.9). CONCLUSION Patients with worst nutrition parameters (SGA C) showed lower ascorbic acid serum levels than those classified as SGA A or B. These results are in accordance with reduced vitamin C intake and the presence of acute phase response.

Abstract
Objective Malnutrition is a common problem in patients with liver cirrhosis and tools for nutritional assessment are under debate. We conducted this study to assess prevalence of malnutrition in cirrhotic patients using PCM score and BIA. Additionally we compared BIA to PCM score for detecting malnutrition in this patient population. Results This was a cross sectional study conducted in two tertiary care hospitals of Karachi Pakistan on adults with liver cirrhosis. Malnutrition was assessed by PCM score using anthropometric measurements and biological specimens and (ii) Body cell mass was assessed using BIA. Malnutrition as estimated by the PCM score was present in 122 (73%) of patients in which most patients had mild malnutrition (n = 72 (45%)), followed by 34 (21%) with moderate malnutrition and 3 (1.9%) with severe malnutrition. Malnutrition according to BIA estimated through body cell mass could detect it in 98 (61%) of patients. There was optimal correlation of PCM score with body call mass (Pearson correlation coefficient = 0.3 (p value 0.001)). We conclude that majority of the patients with liver cirrhosis had malnutrition as determined by PCM score. BIA underscored the malnutrition in this patient population.

To salt or not to salt?-That is the question in cirrhosis. Liver Int 2018; 38:1148-1159.

Abstract
Ascites is the most common complication of patients with cirrhosis, resulting from portal hypertension and vasodilatation. It is associated with an increased risk for the development of hyponatraemia and renal failure and has a high mortality rate of 20% per year. The development of ascites represents a baleful sign in the course of disease in cirrhosis. To prevent complications of cirrhosis and improve quality of life, an effective management of ascites is pivotal. Combined salt restriction and diuretic therapy is recommended as first-line therapy in numerous clinical practice guidelines. In contrast, there has been a debate on whether a strict salt-restricted diet for cirrhosis patients should be used at all since salt restriction may increase the risk for malnutrition which in turn may negatively impact on quality of life and survival. This review aims to summarize the current pros and cons regarding salt restriction in patients with cirrhosis and proposes the importance of achieving a sodium balance throughout different stages of cirrhosis.

Association of Mac-2-binding protein glycosylation isomer level with nutritional status in chronic liver disease. J Gastroenterol Hepatol 2018; 33:1649-1658. [PMID: 29473206 DOI: 10.1111/jgh.14130] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/14/2017] [Revised: 01/25/2018] [Accepted: 02/18/2018] [Indexed: 12/11/2022]
Abstract
BACKGROUND AND AIM Mac-2-binding protein glycosylation isomer (M2BPGi) was recently identified as a serum glycobiomarker for liver fibrosis. However, the relationship between M2BPGi and malnutrition in patients with chronic liver disease (CLD) is unknown. We aimed to evaluate whether M2BPGi could be a surrogate marker for malnutrition in patients with CLD. METHODS In total, 338 outpatients with CLD were enrolled (median age: 67 years). We evaluated the associations among liver fibrosis markers (M2BPGi, fibrosis-4 index, and aspartate aminotransferase-to-platelet count ratio index), Child-Pugh stages, and nutritional status markers. RESULTS The median value (range) of serum M2BPGi levels was 0.94 cut-off index (COI) (0.22-11.57) in chronic hepatitis and Child-Pugh A (n = 274), 4.775 COI (1.32-16.68) in Child-Pugh B (n = 46), and 11.37 COI (6.03-18.33) in Child-Pugh C (n = 18) (overall significance, P < 0.001). Serum M2BPGi levels showed a strong correlation with serum albumin concentration and controlling nutritional status score (rs = -0.649, P < 0.001 and rs = 0.671, P < 0.001, respectively). The correlations between M2BPGi and nutritional status markers were especially high in patients with hepatitis C virus infection and non-B non-C hepatitis and patients with hepatocellular carcinoma. Among the three fibrosis markers, M2BPGi yielded the highest area under the receiver operating characteristic curve (0.920) for predicting hypoalbuminemia at an optimal cut-off value of 2.41 (sensitivity, 87.3%; specificity, 87.6%; P < 0.001). CONCLUSIONS Serum M2BPGi levels are correlated with nutritional status markers in patients with CLD and could be a useful clinical marker of malnutrition.

Abstract
As the cirrhosis progresses, development of complication like ascites, hepatic encephalopathy, variceal bleeding, kidney dysfunction, and hepatocellular carcinoma signify increasing risk of short term mortality. Malnutrition and muscle wasting (sarcopenia) is yet other complications that negatively impact survival, quality of life, and response to stressors, such as infection and surgery in patients with cirrhosis. Conventionally, these are not routinely looked for, because nutritional assessment can be a difficult especially if there is associated fluid retention and/or obesity. Patients with cirrhosis may have a combination of loss of skeletal muscle and gain of adipose tissue, culminating in the condition of "sarcopenic obesity." Sarcopenia in cirrhotic patients has been associated with increased mortality, sepsis complications, hyperammonemia, overt hepatic encephalopathy, and increased length of stay after liver transplantation. Assessment of muscles with cross-sectional imaging studies has become an attractive index of nutritional status evaluation in cirrhosis, as sarcopenia, the major component of malnutrition, is primarily responsible for the adverse clinical consequences seen in patients with liver disease. Cirrhosis is a state of accelerated starvation, with increased gluconeogenesis that requires amino acid diversion from other metabolic functions. Protein homeostasis is disturbed in cirrhosis due to several factors such as hyperammonemia, hormonal, and cytokine abnormalities, physical inactivity and direct effects of ethanol and its metabolites. New approaches to manage sarcopenia are being evolved. Branched chain amino acid supplementation, Myostatin inhibitors, and mitochondrial protective agents are currently in various stages of evaluation in preclinical studies to prevent and reverse sarcopenia, in cirrhosis.

Optimizing the Nutritional Support of Adult Patients in the Setting of Cirrhosis. Nutrients 2017; 9:nu9101114. [PMID: 29027963 PMCID: PMC5691730 DOI: 10.3390/nu9101114] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/28/2017] [Revised: 09/25/2017] [Accepted: 10/09/2017] [Indexed: 12/22/2022] Open
Abstract
Aim: The aim of this work is to develop a pragmatic approach in the assessment and management strategies of patients with cirrhosis in order to optimize the outcomes in this patient population. Method: A systematic review of literature was conducted through 8 July 2017 on the PubMed Database looking for key terms, such as malnutrition, nutrition, assessment, treatment, and cirrhosis. Articles and studies looking at associations between nutrition and cirrhosis were reviewed. Results: An assessment of malnutrition should be conducted in two stages: the first, to identify patients at risk for malnutrition based on the severity of liver disease, and the second, to perform a complete multidisciplinary nutritional evaluation of these patients. Optimal management of malnutrition should focus on meeting recommended daily goals for caloric intake and inclusion of various nutrients in the diet. The nutritional goals should be pursued by encouraging and increasing oral intake or using other measures, such as oral supplementation, enteral nutrition, or parenteral nutrition. Conclusions: Although these strategies to improve nutritional support have been well established, current literature on the topic is limited in scope. Further research should be implemented to test if this enhanced approach is effective.

Abstract
AIMS To investigate the impact of low skeletal muscle mass (LSMM) on survival as compared with protein-energy malnutrition (PEM) in patients with liver cirrhosis (LC). METHODS A total of 206 individuals with LC were analyzed. We retrospectively examined the impact of LSMM, as defined by psoas muscle mass at the third lumber on computed tomography, on survival as compared with PEM. In terms of comparison of the effects of LSMM and PEM on survival, we used time-dependent receiver operating characteristics (ROC) analysis. RESULTS Our study cohort included 115 men and 91 women with a median age of 67 years. There were 140 patients with Child-Pugh A, 62 with Child-Pugh B, and 4 with Child-Pugh C. A total of 117 patients (56.8%) had LSMM and 52 patients (25.2%) had PEM. The proportion of PEM in patients with LSMM (31.62%, 37/117) was significantly higher than in patients without LSMM (16.85%, 15/89) (P = 0.0229). In the multivariate analysis for the entire cohort, the presence of hepatocellular carcinoma, lower body mass index, presence of LSMM, lower triglyceride value, poorer renal function, and higher des-γ-carboxy prothrombin value were found to be significant adverse predictors linked to overall survival, while presence of PEM tended to be significant. In the time-dependent ROC analysis, all area under the ROCs for survival in LSMM at each time point were higher than those in PEM except for Child-Pugh B patients. CONCLUSION In this comparison of LSMM and PEM on clinical outcomes in LC patients, it was shown that LSMM may have stronger prognostic impact than PEM.

Abstract
It is assumed that approximately 24–66% of patients with liver cirrhosis develop malnutrition. Numerous pathological processes lead to serious disorders of nutritional status in this group of patients. Malnutrition in the course of liver cirrhosis is associated with increased morbidity, complications, and low quality of life. Under these conditions, detection of malnutrition is of crucial importance. This review explores the complex mechanisms that lead to malnutrition in the course of liver cirrhosis and focuses on methods used in the assessment of nutritional status in cirrhotic patients. Among others, the role of bioelectrical impedance is highlighted. This noninvasive tool is promising and quite an accurate method of estimating body composition.

Abstract
We aimed to investigate the effect of body mass index (BMI) on the overall survival rates and to identify the risk factors associated with adverse outcomes. A total of 381 adult-to-adult living donor liver transplantations performed were retrospectively analyzed. These patients were classified according to the BMI categories established by the World Health Organization: The underweight group (BMI<18.5 kg/m2 ) and the non-underweight group (BMI≥18.5 kg/m2 ). The underweight group had significantly worse outcomes, compared with that of the non-underweight group (5-year overall survival: 45.6% vs 74.6%, P<.001). Underweight patients with CD4/CD8 ratio <1.4 had a significant worse prognosis, compared with those with CD4/CD8 ratio ≥1.4. (The 1-, 3-, and 5-year overall patient survival rates in both groups were 71.0% vs 20%, 58.9% vs 0%, and 53.6% vs 0%, respectively, P=.002.) In the multivariate analysis, only CD4/CD8 ratio <1.4 was an independent poor prognostic factor (hazard ratio=7.063, 95% confidence interval=1.329-37.547, P=.022). CONCLUSIONS Pre-operative CD4/CD8 ratio <1.4 is an independent poor prognostic indicator for underweight patients undergoing liver transplantation. Early intervention in replenishing the nutrient deficit and cautious use of immunosuppressive regimens are essential to prepare this high-risk population for a more successful liver transplantation.

Abstract
We aimed to investigate the impact of decrease of muscle mass on survival after eradication of esophageal varices (EVs) treated by endoscopic therapies as a primary prophylaxis in patients with liver cirrhosis (LC). In all, 177 LC individuals with EVs undergoing endoscopic therapies were analyzed. We retrospectively examined the impact of muscle mass decrease as determined by psoas muscle mass (PMM) at the third lumber on computed tomography (depletion of PMM [DPMM]) on survival as compared with serum sodium combined Model for End-stage Liver Disease (MELD-Na). In comparison of the effects of these parameters, we used time-dependent receiver-operating characteristics (ROC) analysis. We also investigated parameters related to overall survival in the univariate and multivariate analyses. This study included 116 males and 61 females with a median age of 66 years. The median follow-up periods were 2.7 years (range 0.1-9.6 years). In all, 110 patients (62.1%) had DPMM. The median MELD-Na score was 7.200 (range -3.451 to 30.558). The MELD-Na score in patients with DPMM (median 7.685) was significantly higher than that in patients without DPMM (median 6.235) (P = .0212). In the multivariate analysis, presence of hepatocellular carcinoma (P < .0001), presence of DPMM (P < .0001), and MELD-Na ≥7.2 (P = .0438) were revealed to be significant predictors related to overall survival. In time-dependent ROC analyses, all area under the ROCs for DPMM in each time point were higher than those for MELD-Na in the entire cohort and in patients without hepatocellular carcinoma at baseline (n = 133). In conclusion, for LC patients treated by endoscopic therapies for EVs, DPMM had stronger prognostic impact than MELD-Na.

Abstract
UNLABELLED Obesity increases the risk of clinical decompensation in cirrhosis, possibly by increasing portal pressure. Whether weight reduction can be safely achieved through lifestyle (LS) changes (diet and exercise) in overweight/obese patients with cirrhosis, and if weight loss reduces portal pressure in this setting, is unknown. This prospective, multicentric, uncontrolled pilot study enrolled patients with compensated cirrhosis, portal hypertension (hepatic venous pressure gradient [HVPG] ≥6 mm Hg), and body mass index (BMI) ≥26 kg/m2 in an intensive 16-week LS intervention program (personalized hypocaloric normoproteic diet and 60 min/wk of supervised physical activity). We measured HVPG, body weight (BW) and composition, adipokines, health-related quality of life, and safety data before and after the intervention. Changes in HVPG and BW were predefined as clinically relevant if ≥10% and ≥5%, respectively. Safety and BW were reassessed after 6 months. 60 patients were included and 50 completed the study (56 ± 8 years old; 62% male; nonalcoholic steatohepatitis etiology 24%; BMI 33.3 ± 3.2 kg/m2 ; Child A 92%; HVPG ≥10 mm Hg, 72%). LS intervention significantly decreased BW (average, -5.0 ± 4.0 kg; P < 0.0001), by ≥5% in 52% and ≥10% in 16%. HVPG also significantly decreased (from 13.9 ± 5.6 to 12.3 ± 5.2 mm Hg; P < 0.0001), by ≥10% in 42% and ≥20% in 24%. A ≥10% BW loss was associated with a greater decrease in HVPG (-23.7 ± 19.9% vs. -8.2 ± 16.6%; P = 0.024). No episodes of clinical decompensation occurred. Weight loss achieved at 16 weeks was maintained at 6 months; Child and Model for End-Stage Liver Disease scores did not change. CONCLUSION Sixteen weeks of diet and moderate exercise were safe and reduced BW and portal pressure in overweight/obese patients with cirrhosis and portal hypertension. (Hepatology 2017;65:1293-1305).

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
BACKGROUND Although malnutrition and sarcopenia are prevalent in cirrhosis, their impact on outcomes following liver transplantation is not well documented. METHODS The associations of nutritional status and sarcopenia with post-transplant infections, requirement for mechanical ventilation, intensive care (ICU) and hospital stay, and 1 year mortality were assessed in 232 consecutive transplant recipients. Nutritional status and sarcopenia were assessed using the Royal Free Hospital-Global Assessment (RFH-GA) tool and the L3-psoas muscle index (L3-PMI) on CT, respectively. RESULTS A wide range of RFH-SGA and L3-PMI were observed within similar Model for End-stage Liver Disease (MELD) sub-categories. Malnutrition and sarcopenia were independent predictors of all outcomes. Post-transplant infections were associated with MELD (OR = 1.055, 95%CI = 1.002-1.11) and severe malnutrition (OR = 6.55, 95%CI = 1.99-21.5); ventilation > 24 h with MELD (OR = 1.1, 95%CI = 1.036-1.168), severe malnutrition (OR = 8.5, 95%CI = 1.48-48.87) and suboptimal donor liver (OR = 2.326, 95%CI = 1.056-5.12); ICU stay > 5 days, with age (OR = 1.054, 95%CI = 1.004-1.106), MELD (OR = 1.137, 95%CI = 1.057-1.223) and severe malnutrition (OR = 7.46, 95%CI = 1.57-35.43); hospital stay > 20 days with male sex (OR = 2.107, 95%CI = 1.004-4.419) and L3-PMI (OR = 0.996, 95%CI = 0.994-0.999); 1 year mortality with L3-PMI (OR = 0.996, 95%CI = 0.992-0.999). Patients at the lowest L3-PMI receiving suboptimal grafts had longer ICU/hospital stay and higher incidence of infections. CONCLUSIONS Malnutrition and sarcopenia are associated with early post-liver transplant morbidity/mortality. Allocation indices do not include nutritional status and may jeopardize outcomes in nutritionally compromised individuals.

Abstract
BACKGROUND Hepatitis C is a liver disease that causes significant changes in metabolism, and also has an impact on nutritional status. OBJECTIVE To evaluate the nutritional status and cardiovascular risk in patients with chronic hepatitis C. METHODS This cross-sectional study investigated 58 patients with chronic hepatitis C, non-cirrhotic and were not under active pharmacological treatment. Patients with significant alcohol consumption (greater than 10 g ethanol/day) were excluded. Patients underwent nutritional assessment through anthropometric measurements and functional assessment using hand grip strength by dynamometry. The physical activity was assessed using the International Physical Activity Questionnaire. Patients also underwent clinical and laboratory evaluation. Cardiovascular risk was calculated by the Framingham score. RESULTS The mean age of patients was 51.6±9.7 years, 55.2% were female, and 79.3% had genotype 1. The most prevalent degree of fibrosis was F1 (37.9%) followed by F2 (27.6%) and F3 (1.7%). The prevalence of overweight/obesity considering the body mass index was 70.7%. However, 57.7% of men and 68.8% of women were considered malnourished according to hand grip strength. These patients also had waist circumference (93.5±10.7 cm) and neck circumference (37.0±3.6 cm) high. Almost 60% of patients were considered sedentary or irregularly active. In relation to cardiovascular risk, 50% of patients had high risk of suffering a cardiovascular event within 10 years. CONCLUSION Although most patients with hepatitis C presented overweight, associated with high cardiovascular risk, they also have reduced functional capacity, indicative of protein-caloric commitment. Therefore, body mass index can not be considered the only method of assessment for nutritional diagnosis of patients with liver disease. Adopting methods such as hand grip strength can be important for a better understanding of nutritional status of these patients.

Abstract
The aim of this study was to examine the effect of nonprotein respiratory quotient (npRQ), as assessed using indirect calorimetry, on clinical outcomes in patients with liver cirrhosis (LC). A total of 244 LC patients were evaluated in this study. For the univariate analysis, for each continuous variable, the optimal cutoff value that maximized the sum of sensitivity and specificity was selected using receiver operating curve (ROC) analysis for survival. There were 137 men and 107 women with the median (range) age of 67 (25-90) years. Indirect calorimetry indicated that 54 patients (22.1%) had hepatocellular carcinoma (HCC) on radiological findings and 59 patients (24.2%) had protein energy malnutrition, as defined by npRQ <0.85 and serum albumin level <3.5 g/dL. In ROC analysis of npRQ for survival, the optimal cutoff point of npRQ was 0.849 for all cases (area under the ROC = 0.61272; sensitivity, 66.22%; and specificity, 57.06%). The median follow-up periods after indirect calorimetry were 4.35 years (range, 1.01-9.66 years) in patients with npRQ ≥0.85 (n = 122) and 3.71 years (range, 0.19-9.51 years) in patients with npRQ <0.85 (n = 122). The 1-, 3-, and 5-year cumulative OS rates in patients with npRQ ≥0.85 were 100%, 87.79%, and 77.24%, respectively, whereas those in patients with npRQ <0.85 were 94.26%, 73.65% and 57.78%, respectively (P = 0.0004). In the multivariate analysis, presence of HCC (P = 0.0045), body mass index (P < 0.0001), serum albumin (P = 0.0441), prothrombin time (P = 0.0463), npRQ (P = 0.0024), estimated glomerular filtration rate (P = 0.0086), and des-γ-carboxy prothrombin (P = 0.0268) were found to be significant predictors associated with OS. For all cases, risk stratification for survival was well performed using these significant variables. In conclusion, npRQ value, as assessed by indirect calorimetry, can be helpful for predicting clinical outcomes for LC patients.

Abstract
Serum hyaluronic acid (HA) is a well-established marker of fibrosis in patients with chronic liver disease (CLD). However, the relationship between serum HA level and protein-energy malnutrition (PEM) in patients with CLD is an unknown. We aimed to examine the relationship between serum HA level and PEM in patients with chronic hepatitis C (CHC) compared with the relationships of other serum markers of fibrosis. A total of 298 CHC subjects were analyzed. We defined patients with serum albumin level of ≤3.5 g/dL and nonprotein respiratory quotient <0.85 using indirect calorimetry as having PEM. We investigated the effect of serum HA level on the presence of PEM. Receiver operating characteristic curve (ROC) analysis was performed for calculating the area under the ROC (AUROC) for serum HA level, platelet count, aspartate aminotransferase (AST) to platelet ratio index, FIB-4 index, AST to alanine aminotransferase ratio, and Forns index for the presence of PEM. The median serum HA level in this study was 148.0 ng/mL (range: 9.0-6340.0 ng/mL). In terms of the degree of liver function (chronic hepatitis, Child-Pugh A, B, and C), the analyzed patients were well stratified according to serum HA level (overall significance, P < 0.0001). The median value (range) of serum HA level in patients with PEM (n = 61) was 389.0 ng/mL (43.6-6340.0 ng/mL) and that in patients without PEM (n = 237) was 103.0 ng/mL (9.0-783.0 ng/mL) (P < 0.0001). Among 6 fibrosis markers, serum HA level yielded the highest AUROC with a level of 0.849 at an optimal cut-off value of 151.0 ng/mL (sensitivity 93.4%; specificity 62.0%; P < 0.0001). In the multivariate analysis, serum HA level was found to be a significant prognostic factor related to the presence of PEM (P = 0.0001).In conclusion, serum HA level can be a useful predictor of PEM in patients with CHC.

Abstract
OBJECTIVE Although the prognosis is known to be poor in cirrhosis patients associated with sarcopenia, the relationships among skeletal muscle, visceral fat, and the liver have not yet been thoroughly investigated. Therefore, the prognosis and its associations with body composition and the severity of liver disease were examined in patients with cirrhosis. METHODS The skeletal muscle mass and visceral fat area were measured in 161 patients with cirrhosis, the effects of body composition on the prognosis were analyzed, and any factors that contribute to changes in body composition were assessed. RESULTS During the mean observation period of 1,005 days, 73 patients died. Patients with sarcopenia or sarcopenic obesity had a poor prognosis, and this difference was pronounced in the subset of patients classified as Child-Pugh class A. A decreased skeletal muscle mass was strongly correlated with decreased serum albumin levels. Sarcopenia is a common feature of advanced cirrhosis, and transitions were observed from normal body composition to sarcopenia and from obese to sarcopenic obesity. CONCLUSION The body composition is a prognostic factor for cirrhosis, and a better body composition may be advantageous for obtaining a long-term survival in patients with cirrhosis.

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
Hepatic encephalopathy (HE) is one of the worst complications of liver disease and can be greatly influenced by nutritional status. Ammonia metabolism, inflammation and muscle wasting are relevant processes in HE pathophysiology. Malnutrition worsens the prognosis in HE, requiring early assessment of nutritional status of these patients. Body composition changes induced by liver disease and limitations superimposed by HE hamper the proper accomplishment of exams in this population, but evidence is growing that assessment of muscle mass and muscle function is mandatory due to the role of skeletal muscles in ammonia metabolism. In this review, we present the pathophysiological aspects involved in HE to support further discussion about advantages and drawbacks of some methods for evaluating the nutritional status of cirrhotic patients with HE, focusing on body composition.

Abstract
BACKGROUND The prevalence of chronic liver disease is increasing in the United States. Malnutrition is common as liver disease progresses. However, an accepted method to screen these patients for malnutrition is lacking. The 6-question undernutrition screening tool was developed for professionals without nutrition training to identify a decline in the nutrition status of patients with liver cirrhosis. A 3-phase validation study was completed to assess face, content, and clinical validity of the screening tool in ambulatory patients with liver cirrhosis. METHODS In phase I, face validity was determined by surveying 13 liver disease professionals. In phase II, content validity was assessed by surveying 12 registered dietitians who specialize in liver disease. In phase III, a cross-sectional investigation was completed to compare the agreement between the undernutrition screening tool and nutrition assessment by a registered dietitian (RD). RESULTS Twenty-two patients with a diagnosis of liver cirrhosis participated in phase III of the investigation. The RD assessment identified undernutrition in 82% of patients (95% CI, 60%-95%). The κ statistic indicated a fair agreement between the screening tool and RD assessment. Sensitivity and specificity of the tool were 72% and 75%, respectively, and positive predictive value was 93%. CONCLUSIONS Feedback from phase I, II, and III indicate that the undernutrition screening tool is simple, is easy to use, and measures the constructs that have the strongest link with undernutrition in liver disease. Additional minor adjustments to the screening tool and a multicenter investigation are indicated to confirm clinical effectiveness and cross-validity of the tool.

Abstract
Liver cirrhosis is the terminal stage of chronic hepatitis, often accompanied by protein-caloric malnutrition (PCM). Many factors may be at play causing an individual with liver cirrhosis to develop malnutrition. Malnutrition is regarded as the important prognostic factor of cirrhosis and is the contraindication to liver transplantation. However, in clinical practice, physicians and nurses often do not detect the presence of malnutrition fully in the population with cirrhosis, nor do they realize its damaging consequences. As a consequence, malnutrition is often overlooked. Given all these, this review focuses on several aspects of nutritional assessment, on the basis of the latest research reports, aiming at having a comprehensive and up-to-date understanding concerning malnutrition in cirrhosis, as well as giving medical providers instructions to perform a clinical nutritional assessment more perfectly.

Association between chronic hepatitis C virus infection and low muscle mass in US adults. J Viral Hepat 2014; 21:938-43. [PMID: 24989435 PMCID: PMC4236264 DOI: 10.1111/jvh.12273] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/06/2013] [Accepted: 05/17/2014] [Indexed: 12/15/2022]
Abstract
Given that low muscle mass can lead to worse health outcomes in patients with chronic infections, we assessed whether chronic hepatitis C virus (HCV) infection was associated with low muscle mass among US adults. We performed a cross-sectional study of the National Health Examination and Nutrition Study (1999-2010). Chronic HCV-infected patients had detectable HCV RNA. Low muscle mass was defined as <10th percentile for mid-upper arm circumference (MUAC). Multivariable logistic regression was used to determine adjusted odds ratios (aORs) with 95% confidence intervals (CIs) of low muscle mass associated with chronic HCV. Among 18 513 adults, chronic HCV-infected patients (n = 303) had a higher prevalence of low muscle mass than uninfected persons (13.8% vs 6.7%; aOR, 2.22; 95% CI, 1.39-3.56), and this association remained when analyses were repeated among persons without significant liver fibrosis (aOR, 2.12; 95% CI, 1.30-3.47). This study demonstrates that chronic HCV infection is associated with low muscle mass, as assessed by MUAC measurements, even in the absence of advanced liver disease.
