Dysphagia risk evaluated by the Eating Assessment Tool-10 is associated with health-related quality of life in patients with chronic liver disease.

OBJECTIVE: This study aimed to reveal the prevalence and characteristics of individuals at risk of dysphagia in patients with chronic liver disease (CLD) and its association with health-related quality of life (HRQOL). METHODS: This cross-sectional study included 335 outpatients with CLD. Dysphagia risk, sarcopenia risk, malnutrition risk, and HRQOL were assessed using the Eating Assessment tool-10 (EAT-10), SARC-F, Royal Free Hospital-Nutrition Prioritizing Tool (RFH-NPT), and Chronic Liver Disease Questionnaire (CLDQ), respectively. Dysphagia risk and low HRQOL were based on EAT-10 ≥3 and CLDQ overall score <5, respectively. Factors associated with dysphagia risk and low HRQOL were assessed using the logistic regression model. RESULTS: Dysphagia risk and lower HRQOL were observed in 10% and 31% of the patients, respectively. Patients with dysphagia risk were older, had lower liver functional reserve, were at higher risk for sarcopenia and malnutrition, and showed lower CLDQ overall score (median, 4.41 vs. 5.69; P < 0.001) than those without. After adjustment, SARC-F (odds ratio [OR], 1.24; 95% confidence interval [CI], 1.02-1.50; P = 0.029) and RFH-NPT (OR, 1.71; 95% CI, 1.04-2.81; P = 0.034) scores were independently associated with dysphagia risk. EAT-10 (OR, 1.17; 95% CI, 1.04-1.30; P = 0.008) and SARC-F (OR, 1.37; 95% CI, 1.18-1.59; P < 0.001) scores were also independently associated with low HRQOL. CONCLUSIONS: Dysphagia risk was prevalent in approximately 10% of patients with CLD and was associated with a risk of sarcopenia and malnutrition. Furthermore, dysphagia risk was related to HRQOL in patients with CLD.

Nutritional counseling improves mortality and prevents hepatic encephalopathy in patients with alcohol-associated liver disease.

AIM: Nutritional counseling improves malnutrition, which determines the prognosis of patients with chronic liver disease. In this study, we investigated the effects of nutritional counseling on mortality and the risk of overt hepatic encephalopathy (HE) in patients with alcohol-associated liver disease. METHODS: In this retrospective cohort study, we included 211 patients with alcohol-associated liver disease who visited Gifu University Hospital between August 2008 and June 2023. Patients were classified into two groups according to the frequency of nutritional counseling by a registered dietitian. The primary outcomes were all-cause mortality and overt HE. Propensity score matching analysis was performed to adjust for potential confounders. RESULTS: Among the patients (median age 67 years; 88% men; and median Model for End-Stage Liver Disease score, 9), 86 (39%) were in the high-frequency (≥2) nutritional counseling group. The high-frequency group had a significantly higher survival rate (46% vs. 25%) and a lower incidence of overt HE (16% vs. 27%) at 5 years than the low-frequency group. Nutritional counseling was associated with a reduced risk of mortality (hazard ratio [HR] 0.48; 95% confidence interval [CI] 0.36-0.63) and overt HE (HR 0.64; 95% CI 0.42-0.99), independent of hepatocellular carcinoma and liver function reserve. After propensity score matching, nutritional counseling was still associated with a reduced risk of mortality (HR 0.34; 95% CI 0.19-0.59) and overt HE (HR 0.31; 95% CI 0.11-0.87). CONCLUSIONS: Nutritional counseling effectively improves mortality and prevents overt HE in patients with alcohol-associated liver disease, thereby proving essential for the management of these patients.

Animal naming test stratifies the risk of falls and fall-related fractures in patients with cirrhosis.

This study aimed to determine the relationship between animal naming test (ANT), falls, and fall-related fractures in patients with cirrhosis. Cognitive impairment and frailty were assessed using ANT and Karnofsky performance status (KPS), respectively. Factors stratifying the risk of previous falls and fall-related fractures within 1 year were assessed using a logistic regression model. Factors affecting patient performance in ANT were evaluated using multiple regression analysis. Of the 94 patients, 19% and 5% experienced falls and fall-related fractures, respectively. The performance in ANT was worse in patients who experienced falls (11 vs. 18; p < 0.001) and fall-related fractures (8 vs. 16; p < 0.001) than in those who did not. After adjustment, females, KPS, and ANT (odds ratio [OR], 0.78; 95% confidence interval [CI], 0.65-0.93; p = 0.005) were associated with falls, while ANT was significantly associated with fall-related fractures (OR, 0.56; 95% CI 0.35-0.88; p = 0.012). Age and education affected the performance in ANT, whereas the use of Oriental zodiac did not. The ANT is useful for stratifying the risk of falls and fall-related fractures in patients with cirrhosis. The effects of age and education should be considered when applying ANT in the Japanese population.

A survey questionnaire evaluating physical activity patterns and determinants in patients with chronic liver disease.

BACKGROUND: Physical activity can reduce the risk of morbidity and mortality in patients with chronic liver disease (CLD), whereas physical inactivity adversely affects clinical outcomes. Since data on physical activity in CLD are scarce, we conducted a questionnaire survey to assess the physical activity patterns and determinants in patients with CLD. METHODS: We surveyed 437 patients from outpatient clinics at Gifu University Hospital about their physical activity patterns and determinants in 2022 using a validated questionnaire. The primary objective was to examine the proportion of patients who exercised and the clinical characteristics of patients who achieved high levels of physical activity. The secondary objectives were to explore the types, motivations, barriers, and preferences for physical activity. RESULTS: Among the 397 eligible patients (median age 68 years; 51% men; and median Model for End-Stage Liver Disease score 6), 55.4% reported performing physical activity less than once a week. Physical activity frequency was not associated with sex, body mass index, comorbidities, or hepatic reserve. Among the respondents, 60.4% expressed concern regarding physical strength, and 80.6% expressed concern regarding physical inactivity. The main barriers to physical activity were work, household chores, and health problems. However, many respondents expressed their willingness to increase their physical activity frequency with some promotional policies. Walking was the most common physical activity practiced in the past year and the activity most respondents wanted to try in the future. CONCLUSIONS: Patients with CLD are insufficiently active and need physical activity interventions, especially regarding walking.

Association between Body Composition and the Risk of Portopulmonary Hypertension Assessed by Computed Tomography in Patients with Liver Cirrhosis.

The aim of this study is to investigate the impact of body composition on the risk of portopulmonary hypertension using computed tomography (CT) in patients with liver cirrhosis. We retrospectively included 148 patients with cirrhosis treated at our hospital between March 2012 and December 2020. POPH high-risk was defined as main pulmonary artery diameter (mPA-D) ≥ 29 mm or mPA-D to ascending aorta diameter ratio ≥ 1.0, based on chest CT. Body composition was assessed using CT images of the third lumbar vertebra. The factors associated with POPH high-risk were evaluated using logistic regression and decision tree analyses, respectively. Among the 148 patients, 50% were females, and 31% were found to be high-risk cases on evaluation of chest CT images. Patients with a body mass index (BMI) of ≥25 mg/m2 had a significantly higher prevalence of POPH high-risk than those with a BMI < 25 mg/m2 (47% vs. 25%, p = 0.019). After adjusting for confounding factors, BMI (odds ratio [OR], 1.21; 95% confidence interval [CI], 1.10-1.33), subcutaneous adipose tissue index (OR, 1.02; 95% CI, 1.01-1.03), and visceral adipose tissue index (OR, 1.03; 95% CI, 1.01-1.04) were associated with POPH high-risk, respectively. In the decision tree analysis, the strongest classifier of POPH high-risk was BMI, followed by the skeletal muscle index. Body composition may affect the risk of POPH based on chest CT assessment in patients with cirrhosis. Since the present study lacked data on right heart catheterization, further studies are required to confirm the results of our study.

Prevalence, association, and prognostic significance of polypharmacy and sarcopenia in patients with liver cirrhosis.

Background and Aim: Polypharmacy and sarcopenia are increasing public health problems worldwide. However, data on the prevalence, association, and prognostic significance of polypharmacy and sarcopenia in patients with liver cirrhosis are limited. Methods: Polypharmacy and sarcopenia were assessed in 239 patients with liver cirrhosis. Polypharmacy was defined as the daily use of six or more medications, and sarcopenia was diagnosed based on muscle strength and mass evaluated on computed tomography. The association between polypharmacy and sarcopenia and their effects on mortality were analyzed using logistic regression and Cox proportional hazards models. Results: Among the 239 patients, 52% were men, the median age was 68 years, and the number of medications used per patient was 6. Further, 53% and 29% patients had polypharmacy and sarcopenia, respectively. The number of medications used and the prevalence of sarcopenia increased with age. Patients with polypharmacy and sarcopenia had similar characteristics, such as older age, increased medication use, advanced liver disease, and decreased muscle strength and mass. After adjusting for confounders, polypharmacy was significantly associated with sarcopenia (odds ratio, 2.11; 95% confidence interval [CI], 1.07-4.17). During the median follow-up of 2.2 years, 62 (26%) patients died. Polypharmacy (hazard ratio [HR], 1.83; 95% CI, 1.01-3.37) and sarcopenia (HR, 2.00; 95% CI, 1.12-3.50) independently predicted mortality. The prognostic significance of polypharmacy was more prominent in older adults than in younger adults (HR, 2.31; 95% CI, 1.01-5.67). Conclusion: Polypharmacy and sarcopenia are interrelated and associated with poor prognosis in patients with cirrhosis. Further large, prospective, population-based studies are required to validate these findings.

A simple covert hepatic encephalopathy screening model based on blood biochemical parameters in patients with cirrhosis.

AIM: Covert hepatic encephalopathy (CHE) adversely affects clinical outcomes in patients with liver cirrhosis, although its diagnosis is difficult. This study aimed to establish a simple CHE screening model based on blood-related biochemical parameters. METHODS: This retrospective study enrolled 439 patients who were assessed for CHE using a neuropsychiatric test between January 2011 and June 2019. A simple CHE (sCHE) score was calculated with hypoalbuminemia (≤ 3.5 g/dL) and hyperammonemia (≥ 80 µg/dL) as 1 point each. The association between sCHE score and CHE or overt hepatic encephalopathy (OHE) was assessed using logistic regression and Fine-Gray competing risk regression models. RESULTS: Of 381 eligible patients, 79 (21%) were diagnosed with CHE. The distribution of sCHE scores was 48% with 0 point, 33% with 1 point, and 19% with 2 points. Patients with sCHE score ≥ 1 point had a higher prevalence of CHE than those with sCHE score of 0 (27% vs. 14%, P = 0.002). A cut-off value of 1 point showed high discriminative ability for identifying CHE, with a sensitivity of 0.67, specificity of 0.56, positive predictive value of 0.27, and negative predictive value of 0.86. During the median follow-up period of 2.2 years, 58 (15%) patients developed OHE. Multivariate analysis showed that sCHE score ≥ 1 (sub-distribution hazard ratio [SHR], 2.69; 95% confidence interval [CI], 1.41-5.15) and CHE (SHR, 2.17; 95% CI, 1.26-3.73) independently predicted OHE. CONCLUSIONS: The sCHE score is a useful screening model for identifying patients with CHE and for predicting OHE occurrence.

A shortened Stroop test to identify covert hepatic encephalopathy and predict overt hepatic encephalopathy in patients with cirrhosis.

BACKGROUND: Covert hepatic encephalopathy (CHE) adversely affects the clinical outcomes of patients with cirrhosis but remains largely undiagnosed and untreated. Although the Stroop test is a useful method for CHE detection, a faster, simpler, and more accurate test is required to diagnose CHE. This prospective study aimed to develop a new shortened Stroop test that can detect CHE and predict overt hepatic encephalopathy (OHE) in Japanese patients with cirrhosis. METHODS: Patients who underwent neuropsychological tests (NPT) and the Stroop test between November 2018 and December 2021 were enrolled and followed until OHE occurrence or March 2022. The discriminative ability of various run combinations in the off and on states to detect CHE was evaluated using the area under the receiver-operating characteristic curve (AUC) and compared with that of the total Stroop test time. RESULTS: Among the 227 eligible patients, the On1-2Time cutoff value of 44.4 s had a comparable discriminative ability with the total Stroop test time to detect CHE, with an AUC of 0.791, a sensitivity of 0.827, and a specificity of 0.685. During a median follow-up period of 16 months, 37 patients developed OHE. On1-2Time ≥ 44.4 s (hazard ratio [HR], 3.93; 95% confidence interval [CI] 1.36-11.36) and serum albumin levels (HR, 0.28; 95% CI 0.11-0.67) were independently associated with OHE occurrence. CONCLUSIONS: The shortened Stroop test (On1-2Time) is equivalent to the total Stroop test not only for identifying CHE but also for estimating the risk of progression to OHE.

Usefulness of the Global Leadership Initiative on Malnutrition criteria to predict sarcopenia and mortality in patients with chronic liver disease.

AIM: The Global Leadership Initiative on Malnutrition (GLIM) criteria, a newly developed global consensus around core diagnostic criteria for malnutrition, needs validation studies for use in daily clinical settings. This study aimed to determine whether the GLIM criteria could predict sarcopenia and mortality in patients with chronic liver disease (CLD). METHODS: We retrospectively reviewed 858 patients with CLD who were treated at our hospital between March 2013 and December 2019. Sarcopenia was diagnosed based on the criteria proposed by the Japan Society of Hepatology. Malnutrition was assessed using the GLIM criteria, subjective global assessment (SGA), and Royal Free Hospital-global assessment (RFH-GA) and their predictive ability for sarcopenia and mortality were assessed using the logistic regression analysis and the Cox proportional hazards regression model, respectively. RESULTS: Among the eligible 406 patients, 67% were men, the median age was 74 years, and 26% had sarcopenia. The prevalence of malnutrition according to the GLIM criteria, SGA, and RFH-GA was 21%, 35%, and 26%, respectively. Comparing malnourished with well-nourished patients, the odds ratio for complicating sarcopenia was 2.54 (95% confidence interval [CI], 1.44-4.49) for the GLIM criteria, 2.13 (95% CI, 1.09-4.15) for the SGA, and 2.78 (95% CI, 1.56-4.95) for the RFH-GA. During a median follow-up period of 2.0 years, 176 (43%) patients died. After adjusting for confounding factors, the GLIM criteria could independently predict mortality (hazard ratio, 1.95; 95% CI, 1.37-2.81). CONCLUSIONS: The GLIM criteria are useful in identifying sarcopenia and predicting mortality in patients with CLD.

Survival benefit of l-carnitine supplementation in patients with cirrhosis.

BACKGROUND: l-Carnitine supplementation is effective in improving muscle cramps, hyperammonemia, and hepatic encephalopathy in patients with cirrhosis. However, limited evidence is available on the effect of l-carnitine supplementation on the survival of patients with cirrhosis. METHODS: In this retrospective study, 674 patients with cirrhosis admitted to Gifu University Hospital or Chuno Kosei Hospital between October 2011 and December 2018 were enrolled. l-carnitine supplementation was defined as the use of l-carnitine for >30 consecutive days during the follow-up period. Propensity score matching was applied to create comparable groups between l-carnitine-treated and untreated patients. Mortality was evaluated using the Cox proportional hazards model. RESULTS: Among the patients, 93 were excluded. Of the remaining 581 patients, 71 (12%) received l-carnitine supplementation. Propensity matching identified 189 patients (63 l-carnitine-treated and 126 untreated patients) with comparable baseline characteristics in both groups. Of the matched patients, 33 (52%) l-carnitine-treated and 74 (59%) untreated patients died during the median follow-up period of 36.3 months. Overall survival was significantly higher in l-carnitine-treated patients than in untreated patients (hazard ratio [HR], 0.66; 95% CI, 0.43-0.99). A subgroup analysis showed that the survival benefit of l-carnitine supplementation was prominent in patients with Child-Pugh Class B or C (HR, 0.39; 95% CI, 0.23-0.68), serum albumin levels ≤3.5 g/dl (HR, 0.59; 95% CI, 0.37-0.95), and ammonia levels ≥90 mcg/dl (HR, 0.50; 95% CI, 0.26-0.97), and in those without sarcopenia (HR, 0.56; 95% CI, 0.35-0.90). CONCLUSION: l-Carnitine supplementation may improve survival in patients with cirrhosis.

Usefulness of the Trabecular Bone Score in Assessing the Risk of Vertebral Fractures in Patients with Cirrhosis.

The trabecular bone score (TBS), a surrogate measure of bone microarchitecture, provides complementary information to bone mineral density (BMD) in the assessment of osteoporotic fracture risk. This cross-sectional study aimed to determine whether TBS can identify patients with liver cirrhosis that are at risk of vertebral fractures. We enrolled 275 patients who completed evaluations for lumbar BMD, TBS, and vertebral fractures between November 2018 and April 2021. BMD was measured using dual-energy X-ray absorptiometry (DXA), TBS was calculated by analyzing DXA images using TBS iNsight software, and vertebral fractures were evaluated using Genant's semi-quantitative method with lateral X-ray images. Factors associated with vertebral fractures and their correlation with the TBS were identified using regression models. Of the enrolled patients, 128 (47%) were female, the mean age was 72 years, and 62 (23%) were diagnosed with vertebral fractures. The prevalence of vertebral fractures was higher in women than in men (33% vs. 14%; p < 0.001). The unadjusted odds ratio (OR) of the vertebral fractures for one standard deviation decrease in TBS and BMD was 2.14 (95% confidence interval [CI], 1.69−2.73) and 1.55 (95% CI, 1.26−1.90), respectively. After adjusting for age, sex, and BMD, the adjusted OR of the vertebral fractures in TBS was 2.26 (95% CI, 1.52−3.35). Multivariate linear regression analysis showed that TBS was independently correlated with age (ß = −0.211), body mass index (ß = −0.251), and BMD (ß = 0.583). TBS can help identify patients with cirrhosis at risk of vertebral fractures.

Handgrip strength stratifies the risk of covert and overt hepatic encephalopathy in patients with cirrhosis.

BACKGROUND: Handgrip strength (HGS) is a simple and convenient method to assess nutrition status in patients with cirrhosis. This retrospective study aimed to investigate the utility of HGS for predicting patients with covert hepatic encephalopathy (CHE) and patients at high risk of overt hepatic encephalopathy (OHE). METHODS: We reviewed 963 patients with cirrhosis and consequently enrolled eligible 270 patients. HGS was measured using a digital grip dynamometer. CHE was diagnosed using a computer-aided neuropsychiatric test. Factors associated with CHE were estimated using the logistic regression model. Predictors associated with OHE occurrence were analyzed using the Fine-Gray competing risk regression model. RESULTS: Of the 270 eligible patients, reduced HGS was observed in 102 (38%), reduced muscle mass in 107 (40%), and CHE in 53 (20%). Multivariate analysis showed that serum ammonia levels (odds ratio [OR], 2.23; 95% CI, 1.14-4.36; P = 0.014) and reduced HGS (OR, 3.68; 95% CI, 1.93-7.03; P < 0.001) were independently associated with CHE. During the median follow-up period of 24.5 months, 43 (16%) patients experienced OHE. After adjusting for possible confounding factors, multivariate analysis showed that reduced HGS (subdistribution hazard ratio, 2.36; 95% CI, 1.27-4.38; P = 0.007) was a significant predictor in the development of OHE. CONCLUSION: Patients with reduced HGS had a higher prevalence of CHE and a higher risk for OHE occurrence than those with normal HGS. The measurement of HGS could be a simple bedside modality to stratify the patients' risk for CHE and OHE.

Usefulness of nutritional therapy recommended in the Japanese Society of Gastroenterology/Japan Society of Hepatology evidence-based clinical practice guidelines for liver cirrhosis 2020.

BACKGROUND: The JSGE/JSH guidelines for the management of patients with liver cirrhosis revised in 2020 recommends new strategies for nutritional assessment and intervention, although their usefulness in daily clinical practice is unclear. METHODS: A total of 769 patients with cirrhosis were classified into low-, intermediate-, and high-risk groups according to hypoalbuminemia and sarcopenia, the criteria established for initiating the nutritional therapy algorithm in the guidelines. The association between these groups and mortality was analyzed using a Cox proportional hazards model. The effect of branched-chain amino acids (BCAAs) on survival was evaluated using propensity score matching. RESULTS: Of the enrolled patients, 495 (64%) were men with a median age of 73 years, 428 (56%) had hypoalbuminemia, 156 (20%) had sarcopenia, and 288 (37%) were receiving BCAAs. During a median follow-up period of 1.5 years, 276 (36%) patients died. The intermediate-risk [hazard ratio (HR), 1.60; 95% confidence interval (CI), 1.18-2.18] and high-risk (HR, 2.85; 95% CI, 1.92-4.23) groups independently predicted mortality. Among the propensity score-matched 250 patients, 49 (39%) BCAA-treated and 58 (46%) untreated died. Overall survival was higher in BCAA-treated patients than in untreated patients (HR, 0.67; 95% CI, 0.46-0.98). The survival benefit of BCAAs was pronounced in the intermediate-risk (HR, 0.50; 95% CI, 0.31-0.80) and high-risk (HR, 0.38; 95% CI, 0.16-0.91) groups. CONCLUSIONS: The 2020 JSGE/JSH guidelines for liver cirrhosis are useful in stratifying the mortality risk and providing effective nutritional interventions for malnourished patients with cirrhosis.

Usefulness of the Stroop Test in Diagnosing Minimal Hepatic Encephalopathy and Predicting Overt Hepatic Encephalopathy.

Minimal hepatic encephalopathy (MHE) adversely affects the clinical outcomes of patients with liver cirrhosis. This prospective study aimed to evaluate the utility of the Stroop test in the diagnosis of MHE and prediction of overt hepatic encephalopathy (OHE) in Japanese patients with cirrhosis. We enrolled 152 patients who underwent the Stroop test between November 2018 and February 2020. MHE was diagnosed using a combination of neuropsychological tests as the gold standard. The enrolled patients were followed up prospectively until the occurrence of OHE or August 2020. The optimal cutoff value of the Stroop test measurements was determined by receiver operating characteristic (ROC) curve analysis, and its predictive ability was assessed using the area under the ROC curve (AUC). Among the 139 eligible patients, 50 (36%) were diagnosed with MHE. The OffTime+OnTime cutoff value of 218.3 seconds had the best discriminative ability for MHE diagnosis, with an AUC of 0.77, a sensitivity of 74%, and a specificity of 75%. During a median follow-up of 10.8 months, 6 (4%) patients developed OHE. The OffTime+OnTime cutoff value of 305.6 seconds had the highest predictive ability for OHE, with an AUC of 0.79, a sensitivity of 67%, and a specificity of 92%. This value predicted OHE occurrence independent of liver functional reserve and prior OHE (hazard ratio, 19.8; P = 0.003). These two cutoff values remained statistically significant even when patients with prior OHE were excluded from the analysis. Conclusion: The Stroop test was useful for diagnosing patients with MHE and predicting OHE in Japanese patients with cirrhosis.

Meiotic spindle size is a strong indicator of human oocyte quality.

PURPOSE: To investigate the relationship between the meiotic spindle size in human metaphase II oocytes and embryo developmental potential after intracytoplasmic sperm injection (ICSI). METHODS: Analyzed were 1302 oocytes with a visible meiotic spindle from 281 patients aged under 40 years undergoing ICSI cycles. The meiotic spindle was imaged by using PolScope before ICSI. The oocytes were classified into three groups, according to spindle size: group A (<90 µm2), group B (90-120 µm2), and group C (>120 µm2). RESULTS: Overall, 389 (29.9%) oocytes were classified into group A, 662 (50.8%) into group B, and 251 (19.3%) into group C. The fertilization rate of the group B oocytes was significantly higher than for the A and C oocytes. The blastocyst formation rate in group B was significantly higher than in group A. In addition, the pregnancy rate in group B was significantly higher than in the other two groups. CONCLUSION: The oocytes with a spindle size of 90-120 µm2 showed higher fertilization, blastocyst formation, and clinical pregnancy rates than those with larger or smaller spindles. The measurement of the meiotic spindle size thus has a positive predictive value for identifying human embryo developmental potential clinically.

Prevalence of Sarcopenia and Its Relationship with Nutritional State and Quality of Life in Patients with Digestive Diseases.

This study aimed to clarify the prevalence of sarcopenia, which is characterized by loss of skeletal muscle mass and strength, and its relationship with nutritional state and quality of life (QOL) in patients with digestive diseases. This study enrolled 303 patients (187 men and 116 women with a median age of 70 y) having digestive diseases. Diseases were gastrointestinal in 99 patients, biliary/pancreatic in 93, and hepatic in 111. Skeletal muscle cross-sectional area was measured by abdominal computed tomography at the 3rd vertebra (L3) level. Sarcopenia was defined using the L3 skeletal muscle index and hand grip strength. Nutritional state was assessed by Subjective Global Assessment (SGA), Mini nutritional Assessment®-Short Form (MNA®-SF), anthropometry, and blood biochemistry. QOL was evaluated by Short Form-8TM. Prevalence of sarcopenia was 32.0% in overall cases. The value was 22.2% in gastrointestinal disease, 36.6% in biliary/pancreatic disease, and 36.9% in hepatic disease. Advanced age, male sex, and advanced cancer state were associated with development of sarcopenia. Patients with sarcopenia had a significantly worse nutritional state according to SGA and MNA®-SF than those without sarcopenia. In anthropometry, % arm muscle area, % calf circumference, and body mass index were significantly lower in the sarcopenic group. Serum albumin and hemoglobin were also significantly lower in the sarcopenia patients. QOL was more impaired in physical component subscales in sarcopenia patients than non-sarcopenia ones. Patients with digestive diseases frequently suffer from sarcopenia and this is associated with worsening of nutritional state and QOL in these patients.

Sarcopenia impairs prognosis of patients with liver cirrhosis.

OBJECTIVE: Sarcopenia is characterized by the loss of skeletal muscle mass, and is reported to appear in patients with liver cirrhosis (LC). The aim of this study was to investigate the prevalence of sarcopenia in patients with LC, and to test the association between sarcopenia and patient outcomes. We also analyzed the effect of branched-chain amino acid (BCAA) supplementation on sarcopenic LC. METHODS: Clinical and blood biochemical data of 130 patients with LC who underwent abdominal computed tomography scan were analyzed in this retrospective study. The cross-sectional area of skeletal muscles was measured at the level of the third lumbar vertebra on the scan. The skeletal muscle index was calculated to identify sarcopenia. Cirrhotic patients who were treated with BCAA supplementation of 12 g/d for ≥ 1 y were defined as the BCAA group, and the effect of BCAA on sarcopenic LC was evaluated. RESULTS: Sixty-eight percent of all patients (82% of men and 50% of women) were diagnosed with sarcopenia. Male sex (P = 0.01) and body mass index (P < 0.0001) were predictors of sarcopenia. The multivariate Cox proportional hazards model found BCAA supplementation (hazard ratio [HR], 0.38; P = 0.01), sarcopenia (HR, 3.03; P < 0.01), and Child-Pugh classes B (HR, 2.39; P = 0.03) and C (HR, 5.49; P < 0.001) to be independently associated with mortality. The mortality of sarcopenic LC was significantly higher than that of non-sarcopenic LC (P = 0.01). Moreover, BCAA supplementation improved the survival of sarcopenic patients in subgroup analysis (P < 0.01). CONCLUSIONS: Sarcopenia is significantly associated with mortality in patients with LC. BCAA supplementation might be associated with improved survival of such patients.

Free fatty acid as a marker of energy malnutrition in liver cirrhosis.

AIM: Protein-energy malnutrition is frequently observed in patients with liver cirrhosis (LC). Non-protein respiratory quotient (npRQ) measured by indirect calorimetry is a good marker to estimate energy malnutrition, and predicts the prognosis of patients with LC. However, measurement of npRQ is limited because of the high cost of indirect calorimetry. Our aim was to find out an alternative marker to npRQ that can be used in the routine clinical setting. METHODS: One hundred and fifty-six patients with LC were enrolled in this study. Indirect calorimetry and blood examinations were conducted after overnight fasting, and anthropometry was performed by an expert dietician. The correlation between npRQ and other parameters were calculated by simple and multiple regression analysis. Receiver-operator curve (ROC) analysis was used to identify the cut-off value that would best predict the threshold npRQ of 0.85. RESULTS: Plasma levels of free fatty acid (FFA) was significantly correlated with npRQ value by simple (r = -0.39, P < 0.0001) and multiple regression analysis (t = -2.96, P = 0.0052). Free fatty acid rose in parallel with the increasing disease severity as defined by Child-Pugh classification (P < 0.05). FFA was also correlated with increasing oxidation rate of fat (r = 0.38, P < 0.0001) and decreasing oxidation rate of carbohydrate (r = -0.39, P < 0.0001). The cut-off value of FFA to predict npRQ = 0.85 was 660 µEq/L by ROC analysis. CONCLUSION: FFA is a useful alternative marker to represent npRQ in patients with LC.

Nutritional status and quality of life in current patients with liver cirrhosis as assessed in 2007-2011.

AIM: Current guidelines recommended adequate nutritional support for patients with liver cirrhosis to improve clinical outcome and quality of life (QOL). However, these evidences were obtained more than 10 years ago when malnutrition prevailed. In recent years, the impact of obesity on liver damage and carcinogenesis has grown. We attempted to elucidate the nutritional state and QOL in present cirrhotics. METHODS: A research group supported by the Ministry of Health, Labor and Welfare of Japan recruited 294 cirrhotics between 2007 and 2011. Subjects comprised 171 males and 123 females, 158 of whom had hepatocellular carcinoma (HCC) and Child-Pugh grades A : B : C were 154:91:49. Anthropometry, blood biochemistry and indirect calorimetry were conducted, and QOL was measured using Short Form-8. RESULTS: The mean body mass index (BMI) of all patients was 23.1 ± 3.4 kg/m(2) , and 31% showed obesity (BMI ≥ 25.0). In subjects without ascites, edema or HCC, mean BMI was 23.6 ± 3.6, and 34% had obesity. Protein malnutrition defined as serum albumin of less than 3.5 g/dL and energy malnutrition as respiratory quotient of less than 0.85 appeared in 61% and 43%, respectively, and protein-energy malnutrition (PEM) in 27% of all subjects. Among subjects without HCC, each proportion was 67%, 48% and 30%, respectively. QOL was significantly lower on all subscales than Japanese national standard values, but was similar regardless the presence or absence of HCC. CONCLUSION: While PEM is still present in liver cirrhosis, an equal proportion has obesity in recent patients. Thus, in addition to guidelines for PEM, establishment of nutrition and exercise guidelines seems essential for obese patients with liver cirrhosis.

Indirect calorimetry and anthropometry to estimate energy metabolism in patients with liver cirrhosis.

Energy malnutrition worsens survival in patients with liver cirrhosis, and is currently defined as non-protein respiratory quotient (npRQ) <0.85, as measured by indirect calorimetry. However, measurement of this npRQ is limited because of the high cost of indirect calorimetry. Therefore, we sought an alternative marker that can be used in the routine clinical setting. Forty-four inpatients with cirrhosis were recruited in this study. The last meal was served at 18:00 h on the previous day, and indirect calorimetry was performed between 07:00 and 09:00 h while the patients were still in bed. Fasting blood samples were collected in the early morning on the day of the test. Anthropometry was performed by an expert dietician. The correlations among npRQ, Child-Pugh score of disease severity, laboratory parameters, %AC (arm circumference), %TSF (triceps skinfold thickness), and %AMC (arm muscle circumference) were studied using simple linear regression analysis. ROC (Receiver operating characteristic) analysis was used to identify the cut-off values that would best predict npRQ=0.85. npRQ correlated significantly with %AC (r(2)=0.204, p=0.0021) and %AMC (r(2)=0.178, p=0.0043) but not with %TSF. npRQ was not significantly correlated with other laboratory or anthropometric measurements. The cut-off value for %AC that showed the largest AUC (area under the curve) by ROC analysis was 95, while that for %AMC was 92. Multiple regression analysis yielded an equation; npRQ=0.0019×(%AC)20.0134×(Child-Pugh score)+0.7791. Patient stratification by %AC=95 or by regression equation-based npRQ=0.85, but not by %AMC=92, produced significant difference in survival curves. %AC and regression equation could represent npRQ to some extent as parameters of energy nutrition in cirrhosis.
