Malnutrition negatively impacts the quality of life of patients with cirrhosis: An observational study

Forgettable in the care of liver cirrhosis: the unseen culprits of progression from bad to worse

Patients with liver cirrhosis constitute a critically ill and unique population, and their stability relies on a well-coordinated multidisciplinary team with a carefully structured plan. Overlooking any aspect of this plan can expedite disease progression, leading to severe complications. The lack of disease-specific nutritional guidance, the prevalent sedentary lifestyle among patients, and insufficient screening for hepatocellular carcinoma, oesophageal varices, sarcopaenia, minimal hepatic encephalopathy, and diabetes mellitus, along with fibrosis progression and cirrhosis decompensation, can add further complexities. Additionally, devaluing the impact of obesity in triggering liver cirrhosis can be disadvantageous. Prolonged and inappropriate use of proton pump inhibitors also poses a significant challenge with a wide range of complications. These often-unheeded aspects in the care of liver cirrhosis patients represents the unseen culprits of progression from bad to worse and warrant serious consideration.

Nutritional status in patients with chronic pancreatitis and liver cirrhosis is related to disease conditions and not dietary habits

Malnutrition is a common complication of chronic pancreatitis (CP) and liver cirrhosis (LC). Inadequate food intake is considered a relevant driver of malnutrition in both entities. However, the contribution of habitual diet to impaired nutritional status is unclear. In a prospective, multicenter cross-sectional study, we recruited patients with confirmed CP or LC and healthy volunteers as a control group. Malnutrition was diagnosed according to the Global Leadership Initiative on Malnutrition criteria. We comprehensively investigated habitual dietary intake on nutrient, food group, and dietary pattern level applying two validated food frequency questionnaires. We included 144 patients (CP: n = 66; LC: n = 78) and 94 control subjects. Malnutrition was prevalent in 64% and 62% of patients with CP or LC, respectively. In both CP and LC, despite slightly altered food group consumption in malnourished and non-malnourished patients there were no differences in energy or nutrient intake as well as dietary quality. Compared to controls patients showed distinct dietary food group habits. Patients consumed less alcohol but also lower quantities of fruits and vegetables as well as whole grain products (p < 0.001, respectively). Nevertheless, overall dietary quality was comparable between patients and healthy controls. Nutritional status in CP and LC patients is rather related to disease than habitual dietary intake supporting the relevance of other etiologic factors for malnutrition such as malassimilation or chronic inflammation. Despite distinct disease-related differences, overall dietary quality in patients with CP or LC was comparable to healthy subjects, which suggests susceptibility to dietary counselling and the benefits of nutrition therapy in these entities.

Power of mortality prediction in patients awaiting liver transplantation according to the Global Leadership Initiative on Malnutrition criteria and Subjective Global Assessment and Royal Free Hospital Global Assessment scores

OBJECTIVES

This study aimed to analyze the performance of the Global Leadership Initiative on Malnutrition (GLIM) criteria and Subjective Global Assessment (SGA) and Royal Free Hospital Global Assessment (RFH-GA) scores in predicting 12-mo mortality in patients awaiting liver transplantation.

METHODS

This is a longitudinal observational study, carried out between March 2019 and November 2021. Clinical data were collected and nutritional assessment was performed through anthropometry and application of validated instruments, such as the SGA, GLIM criteria, and RFH-GA. A Cox regression model was carried out, in which the dependent variable was mortality in 1 y, and the independent variables were the classifications of nutritional status by the different methods.

RESULTS

The sample consisted of 126 patients, most of them male (56.35%). Malnutrition was diagnosed in 85.71% of the patients according to the RFH-GA, 62.70% according to the SGA, and 56.31% according to the GLIM criteria. Malnutrition assessed by GLIM was related to a 3.79-fold increase in the chance of mortality over time in patients awaiting liver transplantation. Moreover, the GLIM criteria had good discriminatory power in identifying mortality in patients awaiting liver transplantation, compared with the initial and final SGA and RFH-GA scores and the Model for End-stage Liver Disease-Sodium (MELD-Na) index.

CONCLUSIONS

The GLIM criteria were a good predictor of increased risk of mortality in malnourished patients with chronic liver disease awaiting liver transplantation, compared with the SGA and RFH-GA scores and the MELD-Na index.

The relationship between patient-reported health-related quality of life and malnutrition risk in cirrhosis: an observational cohort study

Patients with cirrhosis experience worse health-related quality of life (HRQoL), and attempts are warranted further exploration of modifiable factors to improve HRQoL. Data on the impact of malnutrition risk on HRQoL among cirrhosis are limited; thus, we aimed to strengthen understanding by clarifying the relationship between nutritional status and low HRQoL in patients with decompensated cirrhosis. Consecutive inpatients with cirrhosis attending our department within a tertiary hospital were studied. Generic health profiles and malnutrition risk were evaluated by the EuroQol-5D (EQ-5D) and Royal Free Hospital-Nutritional Prioritizing Tool (RFH-NPT) score, respectively. Multiple linear regression analysis was used to determine association of malnutrition risk with low HRQoL. In this cohort of 364 patients with median age of 64 years and 49·5 % male, 55·5 % of the study population reported impairment pertinent to HRQoL in at least one dimension in terms of the EQ-5D. Moreover, malnutrition risk (RFH-NPT score: β coefficient = -0·114, P = 0·038) was proved to be independently associated with poor HRQoL in multiple analysis, after adjustment for significant variables like age, BMI and markers of decompensation. Notably, we found that health dimensions representing physical function (i.e. mobility, self-care and usual activities) are substantially affected, while malnourished patients reported less frequencies of complaints in other domain such as anxiety/depression. In conclusion, the risk of malnutrition assessed by the RFH-NPT score is independently associated with low HRQoL. It is operational to improve HRQoL by identifying patients at high malnutrition risk and providing timely nutrition treatment.

Effect of long-term aggressive nutrition therapy on survival in patients with alcohol-related cirrhosis: A randomized controlled trial

BACKGROUND

The aim of this study was to assess the effect of long-term aggressive nutritional therapy on clinical outcomes and survival in patients with alcoholic liver cirrhosis (ALC).

METHODS

Malnourished patients assessed by Royal Free Hospital-Subjective Global Assessment (RFH-SGA) were randomized to control group (CG) (35-40 kcal and 1.2 g protein/kg/day; diet alone) or intervention group (IG) (40-45 kcal and 1.5 g protein/kg/day; diet plus polymeric formula) for 3 months. Patients were followed up at 3 and 12 months.

RESULTS

Malnourished patients (age 44.0 ± 9 years; M [100%]; Child A:B:C [%] = 11:39:50) were randomized to the CG (n = 50) or IG (n = 54); 21 patients in CG and 27 in IG completed 3 months of follow-up. The RFH-SGA improved in 7 (33.3%; p = 0.016) in IG vs. 3 (14.2%; p = 0.625) in CG. Over 3 months, increments (CG vs. IG) were seen in calories (1554 ± 972 to 1823 ± 398; p = 0.001 vs.1542 ± 603 to 2254 ± 372; p=0.001), protein (53.1 ± 18.4 to 72.5 ± 19.6; p = 0.001 vs. 53 ± 21 to 86.9 ± 18.8; p = 0.00), dry body weight (64 ± 10 to 66 ± 11; p = 0.04 vs. 60.8 ± 9.2 to 63.2 ± 10.7; p = 0.009), and mid-upper arm circumference (MUAC) (24.7 ± 3.3 to 25.5 ± 3.3; p = 0.116 vs. 23.5 ± 2.7 to 24.1 ± 2.9; p = 0.015), with better ascites resolution in IG (53.3%; p = 0.008) vs. CG (44.4%; p = 0.227). Median 12-month survival was comparable in both the groups (p = 0.864). Irrespective of the intervention group, energy intake > 25 kcal and protein > 0.8 g/kg/day significantly improved 12-month survival.

CONCLUSION

Aggressive nutritional therapy improves nutritional status and resolves ascites, however fails to show long-term survival benefit, though higher calorie and protein intake has the potential to impact survival.

Relationship between symptoms and both stage of change in adopting a healthy life style and quality of life in patients with liver cirrhosis: a cross-sectional study

BACKGROUND

Previous studies of patients with liver cirrhosis have not considered the broad range of symptoms or the association between healthy behavior and quality of life. The purposes of this study were to examine the association between symptoms and adopting exercise and consuming fruits and vegetables and to identify factors associated with quality of life in patients with liver cirrhosis.

METHODS

This cross-sectional study enrolled 91 consecutive patients with liver cirrhosis in one tertiary general hospital in South Korea between February 2016 and January 2017. Each study participant completed a self-administered questionnaire that measured symptom, stage of change in engaging in exercise and consumption of fruits and vegetables, and the Korean version of the 36-item Short-Form Health Survey. Multivariate ordinal logistic regression analysis and multiple regression models was used, respectively, to examine the association between each symptom with stage of change in engaging in exercise and consumption of fruits and vegetables and to evaluate factors affecting quality of life.

RESULTS

Experiencing nausea was associated with more readiness for change in engaging in exercise, but experiencing shortness of breath was associated with less readiness for change in engaging in exercise. Experiencing right upper quadrant pain was associated with more readiness for change in engaging in consumption of fruits and vegetables. Muscle cramps, anorexia, right upper quadrant pain and body pain, itching, ascites or edema, bruising, and change in appearance negatively affected quality of life.

CONCLUSIONS

The results suggest that the types of symptoms experienced by a patient with liver cirrhosis hinder or promote the patient's adoption of exercise and dietary behavior. Experiencing symptoms may negatively affect quality of life. Caregivers should provide supportive care to patients with liver cirrhosis, which includes assessing and managing symptoms to improve quality of life.

Health-related quality of life and fatigue perception in children with congenital adrenal hyperplasia: A Developing nation perspective

INTRODUCTION

Disease chronicity, lifelong medications, Adrenal crisis, and genital surgeries affect the physical, mental, school and social aspects of a child's life and are a cause of great concern to parents regarding the future of their child with Congenital Adrenal Hyperplasia (CAH). The aim of the study was to assess quality of life (QoL) in children and parents of CAH and comparison with healthy children.

MATERIAL AND METHODS

This was a questionnaire-based cross-sectional study in 28 children with classical CAH attending the Pediatric Endocrine clinic at a tertiary-care center in northern India.

RESULTS

CAH children had poorer QoL in School domain (73.6 vs. 90.0; p = 0.034) and significantly lower scores than their healthy peers in General (83.1 vs. 91.7, p = 0.025), Sleep (74.4 vs. 84.2, p = 0.017) domains and total score (80.0 vs. 87.8, p = 0.008) of the Fatigue scale. Parents reported Social (72.4 vs. 84.5; p = 0.009), School (63.8 vs. 90.0; p 0.01) and Total (74.3 vs. 84.2; p = 0.024) QoL were scores significantly lower than parents of healthy children. Parents perceived scores of Fatigue scale were significantly worse in all domains when compared to parents of healthy children. Failure to thrive was found to be a significant risk factor for impaired school (r  = -0.533; p = 0.013) and overall (r = -0.563; p = 0.008) QoL as perceived by the child.

CONCLUSIONS

Children and parents have different perception of QoL for their child. Routine periodic QoL assessment will help in better understanding of child and parent's hidden concerns which remain unaddressed in busy clinical practice.

Oral Health-Related Quality of Life in Chronic Liver Failure Patients Measured by OHIP-14 and GOHAI

Background

Oro-dental diseases are prevalent in chronic liver failure (CLF) patients. The aim of this study was to evaluate the quality of life associated with oral health in candidates for liver transplant surgery.

Materials and Methods

The demographic information of 105 end-stage liver cirrhotic patients was collected. All patients were ordered a panoramic view for pretransplant dental evaluation. The DMFT (decayed-missing-filled tooth) index was calculated for dental examination. The model for end-stage liver disease (MELD) was used for the severity of liver disease. The OHIP-14 (Oral Health Impact Profile) questionnaire and GOHAI (Geriatric Oral Health Assessment Index) questionnaire were applied to evaluate the impact of oral disease on the quality of life.

Results

A total of 79 patients thoroughly completed the questionnaires; 79.7% were male, 32.9% were over 50, and 25.3% were less than 30 years old. Further, 12.7% smoked, 2.5% were illiterate, 64.6% had not finished school, and 10.1% had university degrees. Almost half of the cirrhotic patients were suffering from the disease for more than 3 years. Most complaints reported by the patients as “very often” were becoming self-conscious (13.9%) and being uncomfortable when eating any foods (13.9%) followed by feeling tense (12.8%). There was no significant difference between gender, smoking, age, and MELD score based on quality of life (OHIP and GOHAI) (P > 0.05). The level of education (P = 0.020), duration of disease (P = 0.017), and DMFT index (P = 0.039) had a significant impact on oral health-related quality of life in CLF patients. An inverse relationship was seen between the DMFT index and the quality of life.

Conclusion

Oral health has a high impact on the quality of life of cirrhotic patients. The psychological dimension of oral health is the most debilitating factor affecting the quality of life. This shows the importance of professional oral care, oral health, and self-care education in this group of patients.

Nutritional Assessment and Malnutrition in Patients With Cirrhosis

We sought to determine the incidence and outcomes of malnutrition in patients with cirrhosis. We performed a retrospective chart review of 134 patients listed for liver transplant (LT) to assess the presence and degree of malnutrition identified by the Subjective Global Assessment score at the time of initial transplant evaluation, follow-up nutrition visits, and at the time of transplant. Number of admissions/readmissions to the hospital, reason for hospitalization(s), and length of stay were determined. Malnutrition was prevalent at initial nutrition visit (51.9%) and underdiagnosed. By the time of transplant, 61% of the patients were identified as malnourished. Most patients (52%) were awaiting LT for more than 180 days. The change in Subjective Global Assessment score after the initial nutrition assessment was statistically significant (p ≤ .007), with worsening malnutrition severity. Seventy-one patients (53%) required hospitalization while awaiting transplant, with a median hospital stay of 9 days. Nutrition expertise is required for prompt and accurate diagnosis of malnutrition in patients with cirrhosis. Nurses caring for patients with advanced liver disease are in a prime position to provide guidance to optimize patient outcomes.

Trace element deficiency is highly prevalent and associated with infection and mortality in patients with alcoholic hepatitis

BACKGROUND

Malnutrition is common in patients with alcohol-related liver disease and is associated with outcome in patients with alcoholic hepatitis. Trace elements (cobalt, copper, iron, selenium and zinc) are micronutrients essential for many cellular processes including antioxidant pathways. The prevalence and relevance of trace element deficiency is unknown in alcoholic hepatitis.

AIM

To determine the prevalence of trace element deficiency and its association with clinical outcomes in patients with alcoholic hepatitis.

METHODS

Serum was obtained from patients with alcoholic hepatitis, alcohol-related cirrhosis and healthy volunteers as part of clinical trials, cohort studies and a biobank. Trace element concentration was measured by inductively coupled plasma mass spectrometry. Association of trace element levels with development of infection within 90 days and mortality within 28 and 90 days was evaluated by multivariate logistic regression.

RESULTS

Sera from 302 patients with alcoholic hepatitis, 46 with alcohol-related cirrhosis and 15 healthy controls were analysed for trace element concentration. The prevalence of zinc deficiency (85%) and selenium deficiency (67%) in alcoholic hepatitis was higher than in alcohol-related cirrhosis (72% [p=0.04] and 37% [p<0.001], respectively). Zinc, selenium, copper and chromium were significantly different between groups. Iron deficiency was a predictor of development of infection within 90 days. Zinc deficiency was a predictor of mortality within 28 and 90 days.

CONCLUSION

Trace element deficiency in patients with alcoholic hepatitis is highly prevalent and associated with infection and mortality. Supplementation with selected trace elements may improve clinical outcomes in this patient group but further insight is required of their biological and clinical effects.

The contribution of ascitic fluid to body weight in patients with liver cirrhosis, and its estimation using girth: a cross-sectional observational study

BACKGROUND

There is a high prevalence of malnutrition among people with decompensated liver disease. Standard nutritional screening tools use weight and body mass index (BMI) to identify risk, although these are difficult to measure for those with ascites, often secondary to liver cirrhosis. Dietetic guidance suggests adjusting for ascitic weight by 2.2-14 kg, although there is a lack of evidence to substantiate these values. The present study aimed to measure the contribution of ascitic fluid weight and compare this with the current guidance, as well as to examine whether girth circumference can be used to estimate ascitic weight.

METHODS

A cross-sectional, observational study was conducted over 13 weeks. Participants attending for paracentesis were weighed, their girths measured, and BMI was calculated pre- and post-paracentesis. Fluid removed via paracentesis was recorded. Ethical approval was received (IRAS project ID: 218747).

RESULTS

Eighteen participants underwent paracentesis. The range of ascitic fluid drained was 3.8-19 L [mean (SD) = 8.7 (3.7) L]. Weight difference between pre- and post-paracentesis was in the range 4.5-20 kg [mean (SD) = 8.7 (3.9) kg]. Ascitic fluid weight is shown to be higher in each category (minimal, moderate, severe ascites) than the current guidance values. Weight difference was greater than 14 kg in 11% (n = 2) of participants. A strong, statistically significant relationship (rho = 0.68, P ≤ 0.01) between ascitic weight and pre-paracentesis girth was found. An equation was formulated to enable the estimation of ascitic fluid from pre-paracentesis girth.

CONCLUSIONS

Current dietetic guidance should be re-evaluated to reflect the greater weight differences identified. Measuring girth pre-paracentesis may help to inform dry weight estimation. Further research is required to verify the accuracy of estimating ascitic weight from pre-paracentesis girth.

Factors related to malnutrition in community-dwelling patients with schizophrenia

PURPOSE

This study aims to identify demographic, clinical, and nutritional factors related to malnutrition in community-dwelling patients with schizophrenia.

DESIGN AND METHODS

We used a descriptive cross-sectional design. Between June and July 2016, 188 community-dwelling patients with schizophrenia were included in this study.

FINDINGS

Of the 188 participants, 4.3% were classified as malnourished, and 40.4% were at risk of malnutrition. Living status, body weight, and appetite were significant factors related to malnutrition in community-dwelling patients with schizophrenia.

PRACTICE IMPLICATION

Assessment of nutritional status should be considered along with demographic and nutritional factors in community-dwelling patients with schizophrenia.

Malnutrition Impacts Health-Related Quality of Life in Cirrhosis: A Cross-Sectional Study

BACKGROUND

To explore the influence of nourishment state measured by various nutrition assessment tools (NATs) on health-related quality of life (HRQoL) in a pretransplant population with cirrhosis.

METHODS

We collected demographic, nutrition assessment, and disease specific data on 81 patients. HRQoL was measured with the Short-Form 36 and divided into 8 subscales. Significant relationships between NATs and HRQoL were examined using independent sample t-tests, χ² analyses, correlations, and multiple and logistic regression adjusted for age and gender.

RESULTS

Study mean age was 54.2 years (SD 10.4 years), and 57% were male. Subjective Global Assessment (SGA) was significantly related to all HRQoL subscales, except bodily pain and mental health. In the adjusted regression models, general health, vitality, and social functioning were all significantly lower in patients with poorer nutrition status measured using SGA (adjusted R² = 11%, β = -0.34, p < 0.01; adjusted R² = 8%, β = -0.27, P < 0.05; and adjusted R² = 12%, β = -0.38, P < 0.01, Q4 respectively). Physical functioning improved as hand grip strength increased (adjusted R² = 20%, β = 0.36, P < 0.01). MELDNa demonstrated a significant negative relationship with role-emotional (adjusted R² = 3%, β = 0.25, P < 0.05), and mid-arm circumference did not demonstrate any significant relationships with HRQoL.

CONCLUSIONS

Malnutrition assessed by SGA is associated with lower HRQoL in patients with cirrhosis. Future research should identify if nutrition interventions can effectively improve HRQoL in cirrhosis patients.

Development and predictive validity of the cirrhosis-associated ascites symptom scale: A cohort study of 103 patients

AIM

To develop a scale of domains associated with the health-related quality-of-life (HRQOL) in patients with cirrhosis-related ascites.

METHODS

We initially undertook literature searches and a qualitative study in order to design a cirrhosis-associated ascites symptom (CAS) scale describing symptoms with a potential detrimental impact on health related quality of life (HRQL) (the higher the score, the worse the symptoms). Discriminatory validity was assessed in a validation cohort including cirrhotic patients with (1) tense/severe; (2) moderate/mild; or (3) no ascites (controls). Patients also completed chronic liver disease questionnaire (CLDQ) and the EuroQoL 5-Dimensions 5-Level (EQ-5D-5L) questionnaire evaluating HRQL. The relation between scale scores was analysed using Spearman correlations.

RESULTS

The final CAS scale included 14 items. The equivalent reliability was high (Chronbach’s alpha 0.88). The validation cohort included 103 patients (72% men, mean age 62.4 years). The mean scores for each question in the CAS scale were higher for patients with severe/tense ascites than for mild/moderate ascites and controls. Compared with controls (mean = 9.9 points), the total CAS scale score was higher for severe/tense ascites (mean = 23.8 points) as well as moderate/mild ascites (mean = 18.6 points) (P < 0.001 both groups). We found a strong correlation between the total CAS and CLDQ score (rho = 0.82, P < 0.001) and a moderate correlation between the CAS and the EQ-5D-5L score (0.67, P < 0.001).

CONCLUSION

The CAS is a valid tool, which reflects HRQOL in patients with ascites.

Usefulness of Simplified Nutritional Appetite Questionnaire (SNAQ) in Appetite Assessment in Elder Patients with Liver Cirrhosis

BACKGROUND

Appetite has received little attention in health care and researches in liver cirrhosis. The Simplified Nutritional Appetite Questionnaire (SNAQ), a self-assessment nutritional screening tool, could be used to screen the risk of malnutrition and weight loss. Our objective was to assess the usefulness of SNAQ in appetite assessment in patients with liver cirrhosis.

METHODS

Seventy patients were enrolled. Appetite assessment was applied in the enrolled patients by completing SNAQ. Weight, hemoglobin, albumin, pro-albumin and Child-Pugh class were evaluated and recorded. The correlation between SNAQ score and these indexes was also evaluated. The most discriminating SNAQ value was calculated, which separated the participant at risk of weight loss.

RESULTS

In participants with SNAQ < 14, the BMI, hemoglobin, albumin and pro-albumin were significantly less than those in participants with SNAQ ≥ 14. The correlation between SNAQ and these indexes were also observed (hemoglobin: r = 0.334, p = 0.005; albumin: r = 0.384, p = 0.001; pro-albumin: r = 0.342, p = 0.004; BMI: r = 0.550, p = 0.000). The SNAQ scores reduced along with the increase of Child-Pugh class. An SNAQ score under 11.5 was the best clinical indicator of elder people at risk of weight loss.

CONCLUSIONS

SNAQ can be used to evaluate the appetite loss and predicting the weight loss in patients with liver cirrhosis. The SNAQ tool also can be used by clinicians and nurses to identify patients with a poor appetite who are at risk of weight loss.

Optimizing the Nutritional Support of Adult Patients in the Setting of Cirrhosis

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.

The impact of nutrition on quality of life of patients with hepatitis C

PURPOSE OF REVIEW

The aim of this study was to review the most recent aspects of nutrition and its impact on health-related quality of life (HRQOL) in patients with chronic hepatitis C (CHC).

RECENT FINDINGS

Low HRQOL scores have been found in all stages of hepatitis C virus (HCV) infection. Of the factors linked to HRQOL, three aspects should be emphasized, nutritional status, physical activity and mental health status. Regarding the nutrition and metabolic conditions, a broad spectrum of nutritional disorders may impact on HRQOL of patients with CHC.

SUMMARY

Malnutrition, which is a significant comorbidity in end-stage of all chronic liver diseases, has been recognized as a significant factor related to poor HRQOL. Of note, in individuals chronically infected with HCV, low muscle skeletal mass, an early indicator of undernourishment, precedes the development of cirrhosis. Because of the strict linkage between HRQOL, nutrition and physical activity, the assessment of the musculoskeletal system abnormalities in every patient with CHC, independently of the stage of the liver disease, is of utmost relevance. Maintenance of healthy skeletal muscle is essential to reduce the negative effects of sarcopenia on HRQOL. Otherwise, overweight/obesity and chronic HCV infection can cause insulin resistance, which has been associated with HRQOL impairment.

The Challenges of Nutritional Assessment in Cirrhosis

Purpose of Review

Nutritional status in patients with cirrhosis is very frequently associated with macro- and micronutrient deficiencies. Cirrhosis itself is the cause of malnutrition and nutritional deficiencies but these conditions have to be identified and addressed properly as they can worsen the prognosis of cirrhosis. The goals of this review are to 1) identify and describe the challenges associated with nutritional assessment in cirrhosis and 2) describe recent advancements when using clinical, laboratory, and instrumental tools in the evaluation of malnourished patients with liver diseases.

Recent Findings

The most promising tools for nutritional assessment in cirrhosis include the evaluation of body composition with phase angle obtained by bioelectrical impedance analysis, computed tomography transverse images at the level of third lumbar vertebra. The Royal-Free Hospital global assessment algorithm appears to be helpful but needs further validation.

Summary

Nutritional assessment in cirrhosis is challenging as several factors, including edema, can interfere with it and because of lack of a validated gold standard. Regardless, nutritional assessment methods have been developed in recent years and should gain relevance in the clinical practice.
