Animal naming test stratifies the risk of falls and fall-related fractures in patients with cirrhosis. Sci Rep 2024; 14:4307. [PMID: 38383771 PMCID: PMC10881459 DOI: 10.1038/s41598-024-54951-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/11/2023] [Accepted: 02/19/2024] [Indexed: 02/23/2024] Open
Abstract
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.

Abstract
Body composition has recently been attracting people's attention, not only from a cosmetic standpoint but also from the perspective of health and longevity. The body is classified into three components: fat, bone, and lean soft tissue, and it is common to see an increase in body fat and a decrease in total body muscle mass with aging. Aging-related loss of muscle mass and muscle function is referred to as primary sarcopenia, while sarcopenia caused by disease-specific conditions is referred to as secondary sarcopenia. On the other hand, the liver-muscle axis has been attracting attention in recent years, and it has become clear that the liver and the skeletal muscles interact with each other. In particular, patients with cirrhosis are prone to secondary sarcopenia due to protein-energy malnutrition, which is a characteristic pathophysiology of the disease, suggesting the importance of the organ-organ network. In this review, we would like to outline the latest findings in this field, with a focus on body composition in liver diseases such as liver cirrhosis, fatty liver disease, alcoholic liver disease, and hepatocellular carcinoma.

Short-latency reaction time and accuracy are impaired in patients with cirrhosis: An international multicenter retrospective study. Geriatr Gerontol Int 2024; 24:25-31. [PMID: 37973613 DOI: 10.1111/ggi.14742] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/09/2023] [Revised: 10/16/2023] [Accepted: 11/07/2023] [Indexed: 11/19/2023]
Abstract
AIM The inability to quickly react to an external event can lead to an increased risk for accidents (e.g., falls, car crashes) in patients with cirrhosis. The aim of this study was to determine whether a novel clinically feasible measure of simple reaction time (SRT) and reaction accuracy (RA)-a go/no-go task occurring within 400 ms-could differentiate patients with cirrhosis from controls. METHODS This retrospective study included 160 patients with cirrhosis and 160 controls assessed between January 2010 and October 2022. SRT and RA were evaluated using a ruler drop paradigm and compared using propensity score matching. Factors distinguishing patients with cirrhosis from controls were assessed using logistic regression and receiver operating characteristics curve (ROC) analyses. RESULTS Propensity score matching identified 112 participants in each group with comparable baseline characteristics. As compared with controls, patients with cirrhosis exhibited significantly prolonged SRT (200 vs. 174 ms; P < 0.001) and diminished total RA (63% vs. 73%; P < 0.001). After adjustment for confounding factors, SRT and RA independently identified patients with cirrhosis. ROC analyses showed that SRT more effectively identified patients with cirrhosis than did the number-connection test/trail-making test-B (area under the curve, 0.87 vs. 0.60; P < 0.001). CONCLUSIONS Patients with cirrhosis demonstrated impairments in short-latency cognitive function. Given that SRT and RA are associated with balance, falls, and response to perturbation, these parameters may present a task-specific method to identify patients with cirrhosis at high risk of falls and motor vehicle crashes.

Handgrip strength is a substitutive metric to the GLIM criteria-defined malnutrition and predicts long-term mortality among hospitalized patients with cirrhosis. Nutr Clin Pract 2023; 38:1021-1031. [PMID: 37004207 DOI: 10.1002/ncp.10983] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2022] [Revised: 02/04/2023] [Accepted: 02/26/2023] [Indexed: 04/03/2023] Open
Abstract
BACKGROUND Hospitalized patients with cirrhosis are prone to debilitating health conditions and fluid fluctuations, posing barriers to accurately obtain anthropometric measures and physical examinations as surrogates for muscle mass within the Global Leadership Initiative on Malnutrition (GLIM). We hypothesize the handgrip strength (HGS) would serve as a substitutive metric, by comparing the diagnostic consistency and prognostic accuracy with computed tomography-demarcated skeletal muscle index (SMI)-defined malnutrition according to the GLIM criteria. METHODS Patients with cirrhosis underwent a two-step approach involving nutrition risk screening and those fulfilling GLIM consensus were further diagnosed. The evaluation of muscle mass as one constituent contained in the GLIM criteria was conducted by SMI and HGS, respectively. Consistency test, Kaplan-Meier curve, and multivariate Cox regression were used to assess the performance of GLIM-SMI and GLIM-HGS. RESULTS Among 184 hospitalized patients with cirrhosis, 63 (34.2%) and 78 (42.4%) were diagnosed with malnutrition following GLIM-SMI and GLIM-HGS criteria, respectively. Considering the GLIM-SMI a gold standard, GLIM-HGS had a sensitivity of 87.3% and a specificity of 81.0%. GLIM-HGS criteria denoted good agreement (κ value = 0.858, P < 0.001) as compared with GLIM-SMI. Both criteria were independently associated with 1-year all-cause mortality, whereas GLIM-SMI showed slightly higher hazard ratios. Moreover, HGS positively correlated with SMI in the population alongside more pronounced correlation among patients at nutrition risk. CONCLUSION HGS may serve as a substitutive metric of muscle mass contained in the GLIM criteria to diagnose malnutrition and predict long-term mortality among patients with cirrhosis.

Abstract
INTRODUCTION The synergistic impact of coexistent malnutrition and sarcopenia on morality in hospitalized patients with decompensated cirrhosis remains elusive. This prospective cohort study aimed to delineate the prevalence concerning coexistence of malnutrition and sarcopenia and the prognosticating role on long-term mortality among cirrhosis. METHODS Adult cirrhotic patients with decompensated episodes between 2019 and 2021 were consecutively enrolled. Malnutrition and sarcopenia were diagnosed according to the Global Leadership Initiative on Malnutrition (GLIM) criteria and the European Working Group on Sarcopenia in Older People (EWGSOP2) algorithm, respectively. The entire cohort was divided into three groups: non-malnutrition and non-sarcopenia (NN), malnutrition or sarcopenia, and coexistent malnutrition and sarcopenia (MS). Log-rank test and multivariate Cox regression model were utilized to evaluate survival status and independent risk factors for mortality, respectively. RESULTS Our findings indicated that malnutrition manifested in 44.6% of inpatients with decompensated cirrhosis, while sarcopenia presented in 16.4% of the entire cohort, indicative of a prevalence of 14.7% regarding coexistent malnutrition and sarcopenia. The Kaplan-Meier graphic demonstrated a significant difference regarding survival curves among the three groups, referring to the MS group presented with the lowest survival rate (log-rank test: p < 0.001). Moreover, coexistent malnutrition and sarcopenia were associated with nearly 4 times higher mortality risk (model 1: hazard ratio [HR] = 3.31, 95% confidence interval [CI]: 1.20-9.13, p = 0.020; model 2: HR = 4.34, 95% CI: 1.52-12.4, p = 0.006) in comparison with patients without any condition (NN group). CONCLUSIONS Malnutrition and sarcopenia had superimposed negative impacts on inpatients with decompensated cirrhosis. It is imperative to identify this vulnerable subset to provide prompt therapeutic intervention for better prognosis.

Abstract
Decreased muscle mass and function, also known as sarcopenia, is common in patients with cirrhosis and is associated with a poor prognosis. Although the pathogenesis of this disorder has not been fully elucidated, a disordered gut-muscle axis probably plays an important role. Decreased barrier function of the gut and liver, gut dysbiosis, and small intestinal bacterial overgrowth (SIBO) can lead to increased blood levels of ammonia, lipopolysaccharides, pro-inflammatory mediators, and myostatin. These factors have complex negative effects on muscle mass and function. Drug interventions that target the gut microbiota (long-term use of rifaximin, lactulose, lactitol, or probiotics) positively affect most links of the compromised gut-muscle axis in patients with cirrhosis by decreasing the levels of hyperammonemia, bacterial translocation, and systemic inflammation and correcting gut dysbiosis and SIBO. However, although these drugs are promising, they have not yet been investigated in randomized controlled trials specifically for the treatment and prevention of sarcopenia in patients with cirrhosis. No data exist on the effects of fecal transplantation on most links of gut-muscle axis in cirrhosis; however, the results of animal experimental studies are promising.

Abstract
It remains challenging to identify covert hepatic encephalopathy and predict progression to overt hepatic encephalopathy. Psychometric testing is a widely used diagnostic modality, but it is often inaccurate and difficult to implement in diverse populations, making it a less than ideal assessment. Alternatively, by using easily accessible data from the electronic health record, simple clinical assessment tools, and patient-reported outcomes, we may be better able to predict hepatic encephalopathy across multiple populations. Furthermore, incorporation of patient-reported outcomes into our diagnostic toolset not only aids detection of covert hepatic encephalopathy and prediction of overt hepatic encephalopathy, but also allows us to target therapies and track their impact. Herein, we outline a potential algorithm based on these easily integrated tools to promote patient risk-stratification and early therapeutic intervention.

Abstract
BACKGROUND Dynapenia embraces clinical significance and predictive value separated from skeletal muscle loss among cirrhosis. Moreover, alterations in lipid levels may impact muscle function. It has yet to elucidate the relationship between lipid profiles and muscle strength weakness. We sought to explore which lipid metabolism indicator could be useful to identify patients with dynapenia in daily practice. METHODS A retrospective observational cohort study enrolling 262 cirrhotic patients. Analysis of the receiver operating characteristic (ROC) curve was performed to determine the discriminatory cutoff for dynapenia. Multivariate logistic regression was conducted to assess the association between total cholesterol (TC) and dynapenia. Also, we established a model based on the classification and regression tree method. RESULTS ROC implicated a cutoff of TC ≤ 3.37 mmol/L to identify dynapenia. Patients with TC ≤ 3.37 mmol/L showed significantly lower handgrip strength (HGS; 20.0 vs. 24.7 kg, P = 0.003), lower hemoglobin, lower platelet, lower white blood cell count, lower sodium and higher prothrombin-international normalized ratio. A positive correlation was found between TC and HGS values ( r = 0.1860, P = 0.003). TC remained a significant association with dynapenia after controlling for variables including age, sex, BMI, and the presence of ascites. The decision tree incorporating TC, BMI, and age had a sensitivity of 71.4%, specificity of 64.9%, and an area under ROC of 0.681. CONCLUSION TC ≤ 3.37 mmol/L was significantly associated with the presence of dynapenia. Assessing TC may be helpful for identifying dynapenic patients with cirrhosis in the health care or hospital setting.

Abstract
Chronic liver disease (CLD), including non-alcoholic fatty liver disease (NAFLD) and its advanced form, non-alcoholic steatohepatitis (NASH), affects a significant portion of the population worldwide. NAFLD is characterised by fat accumulation in the liver, while NASH is associated with inflammation and liver damage. Osteosarcopenia, which combines muscle and bone mass loss, is an emerging clinical problem in chronic liver disease that is often underappreciated. The reductions in muscle and bone mass share several common pathophysiological pathways; insulin resistance and chronic systemic inflammation are the most crucial predisposing factors and are related to the presence and gravity of NAFLD and to the worsening of the outcome of liver disease. This article explores the relationship between osteosarcopenia and NAFLD/MAFLD, focusing on the diagnosis, prevention and treatment of this condition in patients with CLD.

Abstract
Sarcopenia, a condition of low muscle mass, quality, and strength, is commonly found in patients with chronic liver disease (CLD) and is associated with adverse clinical outcomes including reduction in quality of life, increased mortality, and complications. A major contributor to sarcopenia in CLD is the imbalance in muscle protein turnover wherein changes in various metabolic factors such as hyperammonemia, amino acid deprivation, hormonal imbalance, gut dysbiosis, insulin resistance, chronic inflammation, etc. have important roles. In particular, hyperammonemia is a key mediator of the liver-gut axis and is known to contribute to sarcopenia by various mechanisms including increased expression of myostatin, increased phosphorylation of eukaryotic initiation factor 2a, cataplerosis of α-ketoglutarate, mitochondrial dysfunction, increased reactive oxygen species that decrease protein synthesis and increased autophagy-mediated proteolysis. Skeletal muscle is a major organ of insulin-induced glucose metabolism, and sarcopenia is closely linked to insulin resistance and metabolic syndrome. Patients with liver cirrhosis are in a hypermetabolic state that is associated with catabolism and depletion of amino acids, particularly branched-chain amino acids. Sarcopenia can have significant implications for nonalcoholic fatty liver disease, the most common form of CLD worldwide, because of the close link between metabolic syndrome and sarcopenia. This review discusses the potential metabolic derangement as a cause or effect of sarcopenia in CLD, as well as interorgan crosstalk, which that might help identifying a novel therapeutic strategies.

Effects of Rifaximin on Circulating Albumin Structures and Serum Ammonia Levels in Patients with Liver Cirrhosis: A Preliminary Study. J Clin Med 2022; 11:jcm11247318. [PMID: 36555935 PMCID: PMC9784744 DOI: 10.3390/jcm11247318] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2022] [Revised: 12/05/2022] [Accepted: 12/07/2022] [Indexed: 12/13/2022] Open
Abstract
Circulating albumin structures, including their oxidized and reduced forms, are involved in hepatic encephalopathy (HE) development. However, the effects of rifaximin, a key drug in HE treatment, on the circulating albumin structure in patients with liver cirrhosis remain unclear. In this multicenter prospective study, eight patients with hyperammonemia (≥80 μg/dL) were enrolled. The circulating albumin structure was evaluated using the ratio of oxidized albumin (human nonmercaptalbumin, HNA). Patients were administered 400 mg rifaximin 3 times/day for 3 months, and laboratory data were assessed at baseline and during observation. Among the eight patients, three were men; the median age and body mass index were 70 years and 26.4 kg/m2, respectively. The median HNA and serum ammonia levels at baseline were 41% and 143 μg/dL, respectively. After rifaximin therapy, HNA showed a decreasing tendency (median; from 41% to 36%, p = 0.321), but serum albumin levels showed no significant change (from 3.5 g/dL to 3.5 g/dL, p = 1.00); serum ammonia levels significantly reduced (median: 143 μg/dL to 76 μg/dL, p = 0.015). Thus, rifaximin reduces serum ammonia levels and may improve circulating albumin structure in patients with cirrhosis. Further large-scale studies are required to confirm these preliminary results.

A simple covert hepatic encephalopathy screening model based on blood biochemical parameters in patients with cirrhosis. PLoS One 2022; 17:e0277829. [PMID: 36449492 PMCID: PMC9710772 DOI: 10.1371/journal.pone.0277829] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/03/2022] [Accepted: 11/03/2022] [Indexed: 12/05/2022] Open
Abstract
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.

Abstract
BACKGROUND Handgrip strength is considered a surrogate for musculoskeletal strength, however there is emerging evidence of an association with cognition. The specific neurocognitive attribute which best associates with grip strength is unknown. METHODS We performed a secondary analysis on baseline data in 49 healthy older adults. Grip strength was corrected for body mass index. Control independent variables included age, Montreal Cognitive Assessment, and Trails B. Experimental variables included a clinical measure of simple reaction time, and clinical and computerized go/no-go tasks. The clinical Go/No-Go measure was determined with ReacStick, a rod-shaped device which - when released by the examiner - requires the participant to decide within 390 ms whether to catch the device or let it fall to the ground. RESULTS Bivariate analysis demonstrated that age and all cognitive measures other than the computer go/no-go response accuracy related to grip strength. Multivariate analyses showed that following inclusion of the control variables, only ReacStick measures (reaction accuracy/simple reaction time) significantly predicted grip strength, explaining an additional 15.90% variance (p = 0.026). In contrast, computerized Go/No-Go accuracy (p = 0.391), response time variability (p = 0.463), and the control variables (p value range = 0.566-0.942) did not predict grip strength. CONCLUSION A short latency (< 390 ms) visuomotor Go/No-Go task independently predicted over 15% of grip strength variance, whereas a slower screen-based Go/No-Go task did not. These findings support the notion that declining grip strength likely reflects sub-clinical brain changes as well as musculoskeletal dysfunction, possibly explaining the potent relationships between grip strength, disability, chronic disease, and mortality.

Abstract
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.

Abstract
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 more than 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% confidence interval [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), albumin levels ≤3.5 g/dL (HR, 0.59; 95% CI, 0.37-0.95), and ammonia levels ≥90 μg/dL (HR, 0.50; 95% CI, 0.26-0.97) and those without sarcopenia (HR, 0.56; 95% CI, 0.35-0.90). CONCLUSION L-carnitine supplementation may improve survival in patients with cirrhosis. CLINICAL RELEVANCY STATEMENT Carnitine is a vitamin-like compound that regulates lipid and energy metabolism. Although it has been recognized that L-carnitine supplementation improves hyperammonemia, hepatic encephalopathy, sarcopenia, and frailty in patients with cirrhosis, the relationship between L-carnitine supplementation mortality remains unknown. The results of our study provide the first evidence that L-carnitine supplementation may improve survival in patients with cirrhosis. L-carnitine supplementation may shed a new light on the nutritional intervention for patients with cirrhosis. This article is protected by copyright. All rights reserved.

Abstract
In the last years the link between the presence of muscular alterations and hepatic encephalopathy (HE), both minimal and overt, has been deeply studied. The pathophysiological background supporting the relationship between muscle depletion, and HE is characterized by an imbalance between the capacity of muscle in ammonia metabolism and trafficking and the inability of the liver in removing ammonia through urea synthesis due to liver failure and/or the presence of porto-systemic shunts. This review will focus on the clinical burden, the physio pathological mechanisms understanding the liver muscle axis and principles of management of muscular alterations in cirrhosis.
