RESUMO
Liver transplant (LT) recipients have a high burden of cognitive impairment risk factors identified in other populations, yet little work has explored cognition in the United States LT population. We characterized prevalence of cognitive impairment (CI) in LT recipients pre-LT and ≥3 months post-LT. Adult LT recipients with cirrhosis but without active pre-LT hepatic encephalopathy (HE) were screened for CI using the Montreal Cognitive Assessment (MoCA) for CI (MoCA <24) both pre-LT and ≥3 months post-LT. The association between cognitive performance and recipient characteristics was assessed using logistic regression. Of 107 LT recipients, 36% had pre-LT CI and 27% had post-LT CI [median (Q1-Q3) MoCA 26 (23-28)]. Each 1-point increase in pre-LT MoCA was associated with 26% lower odds of post-LT cognitive impairment (aOR .74, 95% CI .63-.87, p < .001), after adjusting for recipient age, history of HE, and time since LT. In this study of cirrhosis recipients without active pre-LT HE, cognitive impairment was prevalent before LT and remained prevalent ≥3 months after LT (27%), long after effects of portal hypertension on cognition would be expected to have resolved. Our data expose an urgent need for more comprehensive neurologic examination of LT recipients to better identify, characterize, and address predictors of post-LT cognitive impairment.

GOALS AND BACKGROUND: Patients with cirrhosis undergoing liver transplant evaluation have high rates of pain and mental health comorbidities; both may significantly impair health-related quality of life (HRQL). We investigated the association between pain, anxiety/depression, and HRQL in this population. STUDY: In 62 patients with cirrhosis undergoing liver transplant evaluation, we performed 4 validated assessments to characterize: pain (Brief Pain Inventory-Short Form, BPI-SF), anxiety (Generalized Anxiety Disorder-7), depression (Patient Health Questionnaire-8), and liver-specific HRQL (Chronic Liver Disease Questionnaire). The presence of pain was determined using the BPI-SF screening question. Linear regression was used to identify demographic or clinical factors predictive of pain severity (PS) and interference (PI) and to evaluate the association between pain, anxiety/depression, and HRQL. RESULTS: Seventy-one percent of patients reported pain, 26% had clinical depression, and 24% had moderate-severe anxiety. Neither liver disease severity, nor its complications were associated with pain (PS or PI), but anxiety and depression were predictors of pain on bivariate analysis. Only depression remained a significant predictor of PS (b=0.28, P<0.05) and PI (b=0.30, P<0.05) in multivariable models. HRQL was inversely associated with PS, PI, depression, and anxiety, but only anxiety (b=-0.14, P=0.003) remained associated with HRQL in the adjusted model. CONCLUSIONS: Pain is present in over 70% of patients with cirrhosis undergoing liver transplant evaluation. Anxiety and depression were highly correlated with pain and appeared to be key drivers in predicting poor HRQL. Evaluating and managing mental health comorbidities should be explored as a strategy to improve HRQL in patients with cirrhosis and pain.
RESUMO
Frailty is a critical determinant of outcomes in cirrhosis patients. The increasing use of telemedicine has created an unmet need for virtual frailty assessment. We aimed to develop a telemedicine-enabled frailty tool (tele-liver frailty index). Adults with cirrhosis in the liver transplant setting underwent ambulatory frailty testing with the liver frailty index (LFI) in-person, then virtual administration of (1) validated surveys (eg, SARC-F and Duke Activity Status Index [DASI]), (2) chair stands, and (3) balance. Two models were selected and internally validated for predicting LFI ≥4.4 using: (1) Bayesian information criterion (BIC), (2) C-statistics, and (3) ease of use. Of 145 patients, the median (interquartile range) LFI was 3.7 (3.3-4.2); 15% were frail. Frail (vs not frail) patients reported significantly greater impairment on all virtually assessed instruments. We selected 2 parsimonious models: (1) DASI + chair/bed transfer (SARC-F) (BIC 255, C-statistics 0.78), and (2) DASI + chair/bed transfer (SARC-F) + virtually assessed chair stands (BIC 244, C-statistics 0.79). Both models had high C-statistics (0.76-0.78) for predicting frailty. In conclusion, the tele-liver frailty index is a novel tool to screen frailty in liver transplant patients via telemedicine pragmatically and may be used to identify patients who require in-person frailty assessment, more frequent follow-up, or frailty intervention.

Frailty, a clinical phenotype of decreased physiological reserve, is a strong determinant of adverse health outcomes in patients with cirrhosis. The only cirrhosis-specific frailty metric is the Liver Frailty Index (LFI), which must be administered in person and may not be feasible for every clinical scenario. We sought to discover candidate serum/plasma protein biomarkers that could differentiate frail from robust patients with cirrhosis. A total of 140 adults with cirrhosis awaiting liver transplantation in the ambulatory setting with LFI assessments and available serum/plasma samples were included. We selected 70 pairs of patients on opposite ends of the frailty spectrum (LFI>4.4 for frail and LFI<3.2 for robust) who were matched by age, sex, etiology, HCC, and Model for End-Stage Liver Disease-Sodium. Twenty-five biomarkers with biologically plausible associations with frailty were analyzed using ELISA by a single laboratory. Conditional logistic regression was used to examine their association with frailty. Of the 25 biomarkers analyzed, we identified 7 proteins that were differentially expressed between frail and robust patients. We observed differences in 6 of the 7 proteins in the expected direction: (a) higher median values in frail versus robust with growth differentiation factor-15 (3682 vs. 2249 pg/mL), IL-6 (17.4 vs. 6.4 pg/mL), TNF-alpha receptor 1 (2062 vs. 1627 pg/mL), leucine-rich alpha-2 glycoprotein (44.0 vs. 38.6 µg/mL), and myostatin (4066 vs. 6006 ng/mL) and (b) lower median values in frail versus robust with alpha-2-Heremans-Schmid glycoprotein (0.11 vs. 0.13 mg/mL) and free total testosterone (1.2 vs. 2.4 ng/mL). These biomarkers represent inflammatory, musculoskeletal, and endocrine/metabolic systems, reflecting the multiple physiological derangements observed in frailty. These data lay the foundation for confirmatory work and development of a laboratory frailty index for patients with cirrhosis to improve diagnosis and prognostication.

BACKGROUND AND AIMS: Accumulation of visceral adipose tissue is associated with hepatic inflammation and fibrosis, suggestive of its metabolic and inflammatory properties. We aimed to examine the histologic findings of visceral and subcutaneous adipose tissue and to associate these findings with clinical and radiologic characteristics in patients with cirrhosis. METHODS: Included were 55 adults with cirrhosis who underwent liver transplantation from 3/2017-12/2018 and had an abdominal computed tomography (CT) scan within 6 months prior to transplant. Visceral-to-subcutaneous adipose tissue ratio (VSR) was calculated using visceral (VATI) and subcutaneous adipose tissue index (SATI) quantified by CT at the L3-vertebral level and normalized for height (cm2/m2). VAT (greater omentum), SAT (abdominal wall), and skeletal muscle (rectus abdominis) biopsies were collected at transplant. RESULTS: Majority of patients had VAT inflammation (71%); only one patient (2%) had SAT inflammation. Patients with VAT inflammation had similar median VATI (42 vs 41 cm2/m2), lower median SATI (64 vs 97 cm2/m2), and higher median VSR (0.63 vs 0.37, p = 0.002) than patients without inflammation. In univariable logistic regression, VSR was associated with VAT inflammation (OR 1.47, 95%CI 1.11-1.96); this association remained significant even after adjusting for age, sex, BMI, HCC, or MELD-Na on bivariable analyses. CONCLUSION: In patients with cirrhosis undergoing liver transplantation, histologic VAT inflammation was common, but SAT inflammation was not. Increased VSR was independently associated with VAT inflammation. Given the emerging data demonstrating the prognostic value of VSR, our findings support the value of CT-quantified VSR as a prognostic marker for adverse outcomes in the liver transplant setting.

INTRODUCTION: Loneliness, "a subjective feeling of being isolated", is a strong predictor of adverse health. We characterized loneliness in patients with end-stage liver disease (ESLD) awaiting liver transplantation (LT). METHODS: We surveyed loneliness in ambulatory ESLD adults awaiting LT at 7 U.S. sites using the validated UCLA Three-Item Loneliness Scale, May2020-Jan2021; "lonely"=total ≥5. Liver Frailty Index (LFI) assessed frailty; "frail"=LFI≥4.4. Logistic regression associated loneliness and co-variables. RESULTS: Of 454 participants, median MELDNa was 14 (IQR 10-19) and 26% met criteria for "lonely". Compared to those not lonely, those lonely were younger (57 v. 61y), more likely to be female (48% v. 31%) or frail (21 v. 11%), and less likely to be working (15% v. 26%) or in a committed partnership (52% v. 71%). After multivariable adjustment, frailty (OR=2.24, 95%CI=1.23-4.08), younger age (OR=1.19, 95%CI=1.07-1.34), female sex (OR=1.83, 95%CI=1.14-2.92), not working (OR=2.16, 95%CI=1.16-4.03), and not in a committed partnership (OR=2.07, 95%CI=1.29-3.32) remained significantly associated with higher odds of loneliness. CONCLUSION: Loneliness is prevalent in adults awaiting LT, and independently associated with younger age, female sex and physical frailty. These data lay the foundation to investigate the extent to which loneliness impacts health outcomes in LT, as in the general population.

We examined whether a key psychological trait-resilience, defined as one's ability to recover quickly from difficulties-contributes to the frail phenotype in patients with cirrhosis. Included were 300 adult patients with cirrhosis who underwent outpatient physical frailty testing using the Liver Frailty Index and resilience testing using the Connor-Davidson Resilience Scale (CD-RISC). The Liver Frailty Index was categorized as robust, prefrail-robust, prefrail-frail, and frail; CD-RISC was categorized using population norms as: least, less, more, and most resilient. Linear regression was used to assess factors associated with frailty (by the Liver Frailty Index per 0.1 unit change). Among the most resilient, only 10% were frail; among the least resilient, 29% were frail. In univariable analysis, resilience was strongly associated with the Liver Frailty Index (coef = -0.13 per point increase; 95% confidence interval [CI], -0.20 to -0.60; P < .001) and remained significantly associated with frailty in multivariable adjustment (coef = -0.13, 95% CI -0.19 to -0.07; P < .001). Low resilience is strongly associated with the frail phenotype in patients with cirrhosis. Given that resilience is modifiable, our data suggest that effective interventions to mitigate frailty should include strategies to build resilience in patients with low baseline resilience.

Objective inpatient frailty assessments in decompensated cirrhosis are understudied. We examined the feasibility of inpatient frailty measurements and associations with nonhome discharge, readmission, and all-cause mortality among patients admitted for cirrhosis complications. We conducted a prospective study at 3 liver transplantation (LT) centers. Frailty was assessed using the liver frailty index (LFI). Multivariable logistic and competing risk models evaluated associations between frailty and clinical outcomes. We included 211 patients with median MELD-Na score 21 (interquartile range [IQR],15-27); 96 (45%) were women, and 102 (48%) were on the LT waiting list. At a median follow-up of 8.3 months, 29 patients (14%) were nonhome discharged, 144 (68%) were readmitted, 70 (33%) underwent LT, and 44 (21%) died. A total of 124 patients (59%) were frail, with a median LFI of 4.71 (IQR, 4.07-5.54). Frail patients were older (mean, 59 versus 54 years) and more likely to have chronic kidney disease (40% versus 20%; P = 0.002) and coronary artery disease (17% versus 7%; P = 0.03). Frailty was associated with hospital-acquired infections (8% versus 1%; P = 0.02). In multivariable models, LFI was associated with nonhome discharge (odds ratio, 1.81 per 1-point increase; 95% confidence interval [CI], 1.14-2.86). Frailty (LFI≥4.5) was associated with all-cause mortality in models accounting for LT as competing risk (subhazard ratio [sHR], 2.4; 95% CI, 1.13-5.11); results were similar with LFI as a continuous variable (sHR, 1.62 per 1-point increase; 95% CI, 1.15-2.28). A brief, objective inpatient frailty assessment was feasible and predicted nonhome discharge and mortality in decompensated cirrhosis. Inpatient point-of-care frailty assessment prior to hospital discharge can be useful for risk stratification and targeted interventions to improve physical fitness and reduce adverse outcomes.

BACKGROUND: The 'gold standard' test for the indirect determination of pancreatic function status in infants with cystic fibrosis (CF), the 72-hour fecal fat excretion test, is likely to become obsolete in the near future. Alternative indirect pancreatic function tests with sufficient sensitivity and specificity to determine pancreatic phenotype need further evaluation in CF infants. OBJECTIVE: Evaluation of the clinical utility of both the noninvasive, nonradioactive C-mixed triglyceride (MTG) breath test and fecal elastase-1 (FE1) in comparison with the 72-hour fecal fat assessment in infants with CF. METHODS: C-MTG breath test and the monoclonal and polyclonal FE1 assessment in stool was compared with the 72-hour fecal fat assessment in 24 infants with CF. Oral pancreatic enzyme substitution (PERT; if already commenced) was stopped before the tests. RESULTS: Sensitivity rates between 82% and 100% for CF patients with pancreatic insufficiency assessed by both the C-MTG breath test and the FE1 tests proved to be high and promising. The C-MTG breath test (31%-38%) as well as both FE1 tests assessed by the monoclonal (46%-54%) and the polyclonal (45%) ELISA kits, however, showed unacceptably low-sensitivity rates for the detection of pancreatic-sufficient CF patients in the present study. CONCLUSIONS: The C-MTG breath test with nondispersive infrared spectroscopy (NDIRS) technique, as well as both FE1 tests, are not alternatives to the fecal fat balance test for the evaluation of pancreatic function in CF infants during the first year of life.

Skeletal muscle index (SMI) remains a strong predictor of mortality in cirrhosis patients. However, the extent to which SMI varies by race/ethnicity has not been fully evaluated. Among 317 patients, 55% identified themselves as non-Hispanic White (NHW), 26% Hispanic White (HW), 13% Asian, and 6% Black. There was significant variation in SMI by race/ethnicity; median SMI was lowest in Asian and highest in Black patients. There were significant differences of sarcopenia by race/ethnicity using established SMI cutpoints: 48% NHW, 33% HW, 67% Asian, and 37% Black (P = 0.003). Using these cutpoints, SMI was significantly associated with waitlist mortality only in NHW patients but not in other racial/ethnic groups.
RESUMO
Background: Patients with cirrhosis have significant morbidity and mortality, as well as substantial symptom burden. Objective: We investigated the relationship between symptom burden and inpatient health care utilization among patients with cirrhosis. Methods: Adult patients with cirrhosis being evaluated for or awaiting liver transplantation at an academic institution in the United States completed the Edmonton Symptom Assessment Scale (ESAS), a validated symptom evaluation tool with total scores ranging from 0 to 90. The outcomes of interest were emergency department (ED) visits, nonelective hospitalizations, hospital days, intensive care unit (ICU) admissions, and 30-day readmissions within 6 months. Adjusted incidence rate ratios (IRRs) were used to examine the relationship between ESAS scores and outcomes. Results: Of 233 patients (43% female, median age 61), the median total ESAS score was 16 (interquartile range 6-30). Higher total scores on the ESAS were associated with increased ED visits, hospitalizations, hospital days, and ICU days (all p < 0.04). After adjusting for age, gender, and Model for End-Stage Liver Disease-sodium, ESAS total score remained an independent predictor of ED visits (IRR 1.05, confidence interval [95% CI] 1.00-1.10, p = 0.03). Multivariate ESAS subscale analyses revealed that the physical symptom score was associated with ED visits (IRR 1.09, 95% CI 1.02-1.16, p = 0.01), but the psychological symptom score was not (IRR 1.03, 95% CI 1.00-1.08, p = 0.15). Conclusions: Patient-reported symptoms, particularly physical symptoms, are independently associated with ED visits among patients with cirrhosis being considered for liver transplantation. Further research is needed to examine whether addressing symptoms more aggressively, such as with palliative care co-management, could decrease ED utilization in this population.

Frailty has emerged as a critical determinant of mortality in patients with cirrhosis. Currently, the United Network for Organ Sharing registry only includes the Karnofsky Performance Status (KPS) scale, which captures a single component of frailty. We determined the associations between frailty, as measured by the Liver Frailty Index (LFI), and KPS with waitlist mortality. METHODS: Included were 247 adult patients with cirrhosis listed for liver transplantation without hepatocellular carcinoma from February 2014 to June 2019, who underwent outpatient assessments using the LFI and KPS within 30 days of listing. "Frail" was defined using the established LFI cutoff of ≥4.4. Competing risk models assessed associations between the LFI and KPS with waitlist mortality (death/delisting for sickness). RESULTS: At a median 8 months follow-up, 25 (10%) patients died/were delisted. In this cohort, median Model for End-Stage Liver Disease-Sodium was 17, LFI was 3.9 (interquartile range 3.4-4.5), and KPS was 80 (interquartile range 70-90). In multivariable analysis, LFI (sub-hazard ratio 1.07, per 0.1 unit; 95% confidence interval, 1.01-1.12) was associated with waitlist mortality while KPS was not (sub-hazard ratio 1.00, per 10 units; 95% confidence interval, 0.78-1.29). CONCLUSIONS: Our data suggest that frailty, as measured by the LFI, may be more appropriate at capturing mortality risk than KPS and provide evidence in support of using the LFI more broadly in clinical transplant practice in the outpatient setting.
RESUMO
OBJECTIVES: Although patients with cirrhosis often experience debilitating symptoms, few are referred for palliative care. Frailty is increasingly incorporated in liver transplantation evaluation and has been associated with symptom burden in other populations. We hypothesized that frail patients with cirrhosis are highly symptomatic and thus are likely to benefit from palliative care. METHODS: Patients with cirrhosis undergoing outpatient liver transplantation evaluation completed the Liver Frailty Index (grip strength, chair stands and balance) and a composite of validated measures including the Edmonton Symptom Assessment Scale, distress and quality of life (QOL) measures. RESULTS: Of 233 patients (median age 61 years, 43% women), 22% were robust, 59% prefrail and 19% frail. Overall, 38% of patients reported ≥1 severe symptoms based on preestablished Edmonton Symptom Assessment Scale criteria. Higher frailty categories were associated with increased prevalence of pain, dyspnea, fatigue, nausea, poor appetite, drowsiness, depression and poor well-being (test for trend, all P < 0.05). Frail patients were also more likely to report psychological distress and poor QOL (all P < 0.01). In univariate analysis, each 0.5 increase in liver frailty index was associated with 44% increased odds of experiencing ≥1 severe symptoms [95% confidence interval (CI), 1.2-1.7, P < 0.001], which persisted (odds ratio, 1.3, 95% CI, 1.0-1.6, P = 0.004) even after adjusting for Model for End Stage Liver Disease-Sodium, ascites, hepatic encephalopathy and age. CONCLUSION: In patients with cirrhosis, frailty is strongly associated with physical/psychological symptoms, including pain and depression and poor QOL. Frail patients with cirrhosis may benefit from palliative care co-management to address symptoms and improve QOL.

Background: Bone health and growth during adolescence require adequate total body protein (TBPr). Renutrition for patients with anorexia nervosa (AN) should aim to normalize body composition and to recover both fat mass and TBPr. Objective: We intended to analyze predictors of protein status, including exercise status, in adolescents with AN and to investigate whether weight gain would replenish body protein deficits. Methods: We assessed TBPr in a longitudinal, observational study as height-adjusted nitrogen index (NI) using in vivo neutron activation analysis in 103 adolescents with AN [mean ± SD age, 15.6 ± 1.4 y; body mass index (BMI, in kg/m2), 16.5 ± 1.6] at the commencement of inpatient refeeding (T0), in 56 of these patients 7 mo thereafter as outpatients (T1), and in age-matched controls (C; n = 51, 15.5 ± 2.1 y, BMI 20.7 ± 1.9). Lean tissue and fat mass were assessed by dual-energy X-ray absorptiometry. BMI, BMI standard deviation score, and lean tissue mass were tested as predictors of protein status using receiver operating characteristic analysis. Results: At T0, NI was decreased in AN (AN, 0.88 ± 0.10 compared with C, 1.00 ± 0.08, P < 0.001). In 34%, the patients showed protein depletion. Patients classified as ``exercisers'' had a higher NI than did ``nonexercisers'' (0.89 ± 0.11 compared with 0.85 ± 0.08, P = 0.045). BMI, BMI standard deviation score, and lean tissue mass did not show potential as predictors of protein status. Despite increases in weight (+6.9 ± 4.5 kg), and BMI (+2.5 ± 1.7), protein status did not improve (TBPr T0, 8.0 ± 1.1 kg; T1, 8.1 ± 1.0 kg, P = 0.495). In an AN subgroup at 7 mo matched with controls in age (AN, 16.5 ± 1.1 y; C, 16.2 ± 1.8 y) and BMI (AN, 20.5 ± 1.4; C, 20.7 ± 1.3), protein status was still not normalized in AN (NI: AN, 0.89 ± 0.09 compared with C, 1.00 ± 0.07, P < 0.001). Conclusions: Adolescents recovering from AN remained protein depleted at 7 mo after baseline assessment, even though they were weight restored.
