RESUMO
BACKGROUND AND AIMS: Fatigue is common in patients with advanced liver disease. We investigated fatigue and clinical outcomes among patients with advanced nonalcoholic steatohepatitis (NASH). METHODS: In this study, patients with biopsy confirmed NASH and bridging fibrosis (F3) or compensated cirrhosis (F4) were followed for up to 2 years. The Chronic Liver Disease Questionnaire for Nonalcoholic Steatohepatitis (CLDQ-NASH) fatigue domain at baseline (range, 1-7; lower score indicating worse fatigue) quantified fatigue. The Cox proportional hazards model was used to study time to liver-related clinical events (progression to histologic cirrhosis or hepatic decompensation in F3, hepatic decompensation in F4). RESULTS: Of the 1679 NASH patients with fibrosis, 802 had F3 and 877 had F4 (58 ± 9 years of age, 40% male, 74% type 2 diabetes). During median follow-up of 16 months (interquartile range, 14-18), 15% (n = 123) of NASH F3 patients experienced liver-related events and 3.5% (n = 31) of NASH F4 patients experienced hepatic decompensation. Mean baseline CLDQ-NASH fatigue score in F3 patients was 4.77 ± 1.36; NASH F3 patients who experienced liver-related events had lower baseline scores: 4.47 ± 1.36 vs 4.83 ± 1.35 (P = .0091). The mean fatigue score in F4 was 4.56 ± 1.44; these scores were lower in patients who decompensated in follow-up: 3.74 ± 1.31 vs 4.59 ± 1.43 (P = .0011). The association of lower fatigue scores and risk of liver-related or decompensation events was significant after adjustment for confounders (adjusted hazard ratio per 1 point in fatigue score in F3, 0.85; 95% confidence interval, 0.74-0.97; P = .02; adjusted hazard ratio in F4, 0.62; 95% confidence interval, 0.48-0.81; P = .0004). CONCLUSION: Worse fatigue at baseline is associated with a higher risk of adverse clinical events in patients with NASH-related advanced fibrosis and cirrhosis.

Chronic hepatitis B (CHB) infection is one of the most common causes of cirrhosis and liver cancer worldwide. Our aim was to assess clinical and patient-reported outcome (PRO) profile of CHB patients from different regions of the world using the Global Liver Registry. The CHB patients seen in real-world practices are being enrolled in the Global Liver Registry. Clinical and PRO (FACIT-F, CLDQ, WPAI) data were collected and compared to baseline data from CHB controls from clinical trials. The study included 1818 HBV subjects (48 ± 13 years, 58% male, 14% advanced fibrosis, 7% cirrhosis) from 15 countries in 6/7 Global Burden of Disease super-regions. The rates of advanced fibrosis varied (3-24%). The lowest PRO scores across multiple domains were in HBV subjects from the Middle East/North Africa (MENA), the highest - Southeast/East and South Asia. Subjects with advanced fibrosis had PRO impairment in 3 CLDQ domains, Activity of WPAI (p < 0.05). HBV subjects with superimposed fatty liver had more PRO impairments. In multivariate analysis adjusted for location, predictors of PRO impairment in CHB included female sex, advanced fibrosis, and non-hepatic comorbidities (p < 0.05). In comparison to Global Liver Registry patients, 242 controls from clinical trials had better PRO scores (Abdominal, Emotional, and Systemic scores of CLDQ, all domains of WPAI) (p < 0.05). In multivariate analysis with adjustment for location and clinicodemographic parameters, the associations of PROs with the enrollment setting (real-life Global Liver Registry vs. clinical trials) were no longer significant (all p > 0.10). The clinico-demographic portrait of CHB patients varies across regions of the world and enrollment settings. Advanced fibrosis and non-hepatic comorbidities are independently associated with PRO impairment in CHB patients.

BACKGROUND: Given the association of NAFLD with metabolic risks, a name change to MAFLD is proposed. We compared the long-term outcomes of NAFLD and MAFLD. METHODS: We included patients with fatty liver disease (FLD) from NHANES III and NHANES 2017-2018 (FLD defined as moderate to severe hepatic steatosis by ultrasound for NHANES III and as having a controlled attenuation parameter ≥285 dB/m for NHANES 2017-2018). NAFLD was defined as FLD without other liver diseases and excess alcohol use. Metabolic-associated fatty liver disease (MAFLD) was defined as FLD and metabolic dysfunction per criteria. All NHANES III participants had linked mortality data through December 31, 2015. RESULTS: NHANES III participants (n = 12,878): mean age 43.1 years old; 49.5% male; 20.3% with FLD, 16.5% with NAFLD, and 18.1% with MAFLD. NHANES 2017-2018 participants (n = 4328): mean age 48.0 years old; 49.1% male; 36.8% with FLD, 34.2% with NAFLD, and 36.3% with MAFLD. Excellent concordance was noted between MAFLD and NAFLD diagnosis in both data sets (kappa coefficient = 0.83-0.94). Except for components of each definition (e.g., alcohol use for MAFLD), no other major differences in clinical characteristics were noted. During up to 27 years of follow-up (median of 22.8 years), no differences in cumulative all-cause and cause-specific mortality were noted. In addition to the stage of fibrosis, insulin resistance was a predictor of liver mortality in NAFLD, and alcohol-associated liver disease (ALD) was a predictor of mortality in MAFLD. CONCLUSIONS: MAFLD and NAFLD have similar clinical profiles and long-term outcomes. The increased liver-related mortality among NAFLD is driven by insulin resistance, and among MAFLD is primarily driven by ALD.

BACKGROUND & AIMS: Achieving sustained virologic response (SVR) among patients with hepatitis C virus (HCV) leads to patient reported outcome (PRO) improvement. We aimed to assess the long-term post-SVR PRO trends in HCV patients with cirrhosis. METHODS: Patients with HCV and cirrhosis treated in clinical trials with direct acting antiviral agents (DAAs) who achieved SVR-12 were prospectively enrolled in a long-term registry (clinicaltrials.gov #NCT02292706). PROs were collected every 24 weeks using the Short Form-36v2 (SF-36), CLDQ-HCV, and WPAI-HCV. RESULTS: Pre-treatment baseline data were available for 854 cirrhotic patients who achieved SVR after DAAs. Of these, 730 had compensated (CC) and 124 had decompensated cirrhosis (DCC) before treatment- patients with DCC reported severe impairment in their PROs in comparison to CC patients (by mean -5% to -16% of a PRO range size; p < .05 for 16 out of 20 studied PROs]. After achieving SVR and registry enrollment, significant PRO improvements were noted from pre-treatment levels in 11/20 domains for those with DCC (+4% to +21%) and 19/20 PRO domains in patients with CC (+3% to +17%). Patients with baseline DCC had higher rates of hepatocellular carcinoma and mortality (P < .05). In patients with CC, the PRO gains persisted up to 168 weeks (3.5 years) of registry follow-up. In patients with DCC, the improvements lasted for at least 96 weeks but a declining trend after year 2. CONCLUSIONS: Patients with HCV cirrhosis experience severe PRO impairment at baseline with sustainable improvement after SVR. Though those with DCC experience improvement, there is a decline after 2 years.

BACKGROUND & AIMS: Globally, nonalcoholic fatty liver disease (NAFLD) is a common cause of chronic liver disease. We assessed the clinical presentation and patient-reported outcomes (PROs) among NAFLD patients from different countries. METHODS: Clinical, laboratory, and PRO data (Chronic Liver Disease Questionnaire-nonalcoholic steatohepatitis [NASH], Functional Assessment of Chronic Illness Therapy-Fatigue, and the Work Productivity and Activity Index) were collected from NAFLD patients seen in real-world practices and enrolled in the Global NAFLD/NASH Registry encompassing 18 countries in 6 global burden of disease super-regions. RESULTS: Across the global burden of disease super-regions, NAFLD patients (n = 5691) were oldest in Latin America and Eastern Europe and youngest in South Asia. Most men were enrolled at the Southeast and South Asia sites. Latin America and South Asia had the highest employment rates (>60%). Rates of cirrhosis varied (12%-21%), and were highest in North Africa/Middle East and Eastern Europe. Rates of metabolic syndrome components varied: 20% to 25% in South Asia and 60% to 80% in Eastern Europe. Chronic Liver Disease Questionnaire-NASH and Functional Assessment of Chronic Illness Therapy-Fatigue PRO scores were lower in NAFLD patients than general population norms (all P < .001). Across the super-regions, the lowest PRO scores were seen in Eastern Europe and North Africa/Middle East. In multivariate analysis adjusted for enrollment region, independent predictors of lower PRO scores included younger age, women, and nonhepatic comorbidities including fatigue (P < .01). Patients whose fatigue scores improved over time experienced a substantial PRO improvement. Nearly 8% of Global NAFLD/NASH Registry patients had a lean body mass index, with fewer metabolic syndrome components, fewer comorbidities, less cirrhosis, and significantly better PRO scores (P < .01). CONCLUSIONS: NAFLD patients seen in real-world practices in different countries experience a high comorbidity burden and impaired quality of life. Future research using global data will enable more precise management and treatment strategies for these patients.

BACKGROUND & AIMS: Despite rapidly increasing nonalcoholic fatty liver disease (NAFLD) prevalence, providers' knowledge may be limited. We assessed NAFLD knowledge and associated factors among physicians of different specialties globally. METHODS: NAFLD knowledge surveys containing 54 and 59 questions covering 3 domains (epidemiology/pathogenesis, diagnostics, and treatment) were completed electronically by hepatologists, gastroenterologists (GEs), endocrinologists (ENDOs), and primary care physicians (PCPs) from 40 countries comprising 5 Global Burden of Disease super-regions. Over 24 months, 2202 surveys were completed (488 hepatologists, 758 GEs, 148 ENDOs, and 808 PCPs; 50% high-income Global Burden of Disease super-region, 27% from North Africa and Middle East, 12% Southeast Asia, and 5% South Asian and Latin America). RESULTS: Hepatologists saw the greatest number of NAFLD patients annually: median 150 (interquartile range, 60-300) vs 100 (interquartile range, 35-200) for GEs, 100 (interquartile range, 30-200) for ENDOs, and 10 (interquartile range, 4-50) for PCPs (all P < .0001). The primary sources of NAFLD knowledge acquisition for hepatologists were international conferences (33% vs 8%-26%) and practice guidelines for others (39%-44%). The Internet was the second most common source of NAFLD knowledge for PCPs (28%). NAFLD knowledge scores were higher for hepatologists than GEs: epidemiology, 62% vs 53%; diagnostics, 80% vs 73%; and treatment, 61% vs 58% (P < .0001), and ENDOs scores were higher than PCPs: epidemiology, 70% vs 60%; diagnostics, 71% vs 64%; and treatment, 79% vs 68% (P < .0001). Being a hepatologist or ENDO was associated with higher knowledge scores than a GE or PCP, respectively (P < .05). Higher NAFLD knowledge scores were associated independently with a greater number of NAFLD patients seen (P < .05). CONCLUSIONS: Despite the growing burden of NAFLD, a significant knowledge gap remains for the identification, diagnosis, and management of NAFLD.

Cure of chronic hepatitis C (CHC) can lead to improvement of health-related quality of life and other patient-reported outcomes (PROs). While extensive PRO data for CHC patients who were enrolled in clinical trials are available, similar data for patients seen in real-world practices are scarce. Our aim was to assess PROs of CHC patients enrolled from real-world practices from different regions and to compare them with those enrolled in clinical trials. CHC patients seen in clinical practices and not receiving treatment were enrolled in the Global Liver Registry (GLR). Clinical and PRO (FACIT-F, CLDQ-HCV, WPAI) data were collected and compared with the baseline data from CHC patients enrolled in clinical trials. N = 12,171 CHC patients were included (GLR n = 3146, clinical trial subjects n = 9025). Patients were from 30 countries from 6 out of 7 Global Burden of Disease (GBD) super-regions. Compared with clinical trial enrollees, patients from GLR were less commonly enrolled from High-Income GBD super-region, older, more commonly female, less employed, had more type 2 diabetes, anxiety and clinically overt fatigue but less cirrhosis (all p < 0.001). Out of 15 PRO domain and summary scores, 12 were lower in GLR patients than in subjects enrolled in clinical trials (p < 0.001). In multiple regression models, anxiety, depression, and fatigue were associated with significant PRO impairment in CHC patients (p < 0.05). After adjustment for the clinico-demographic confounders, the association of PRO scores of CHC patients with enrolment settings was no longer significant (all p > 0.05). In conclusion, hepatitis C patients seen in the real-world practices have PRO impairment driven by fatigue and psychiatric comorbidities.

BACKGROUND & AIMS: The profile of chronic liver disease (CLD) in the United States has changed due to obesity trends and advances in treatment of viral hepatitis. We assessed liver transplant listing trends by CLD etiology. METHODS: Adult candidates for liver transplantation were selected from the Scientific Registry of Transplant Recipients (2002 through 2019). We calculated proportion trends for common CLD etiologies at time of placement on the wait list, including chronic infection with hepatitis B virus, chronic infection with hepatitis C virus (HCV), nonalcoholic steatohepatitis (NASH, including cryptogenic cirrhosis), alcohol-related liver disease (ALD) without or with chronic HCV infection, autoimmune hepatitis, primary biliary cholangitis, and primary sclerosing cholangitis, in patients with and without hepatocellular carcinoma (HCC). RESULTS: From the 168,441 patients with known etiology and non-acute liver failure on the liver transplant waitlist, 27,799 patients (16.5%) had HCC. In 2002, the most common etiologies in patients without HCC were chronic HCV infection (37%) and ALD (16%), whereas only 5% had NASH. Among patients with HCC, 58% had chronic HCV infection and 10% had ALD and only 1% had NASH. In 2019, among patients without HCC, NASH was the second leading indication for liver transplantation (28% of patients), after ALD (38% of patients). Among patients with HCC, chronic HCV infection remained the leading indication (40% of patients) but NASH (24% of patients) surpassed ALD (16% of patients) to become the second leading indication. NASH was the leading indication in women without HCC (34%), in patients older than 54 years (36%), and in patients on Medicare (41%). In trend analysis, NASH was the most rapidly increasing indication for liver transplantation in patients without HCC (Kendall tau=0.97; P < .001) and in patients with HCC (tau=0.94; P < .0001). CONCLUSIONS: In an analysis of data from the Scientific Registry of Transplant Recipients (2002 through 2019), we found NASH to be the second most common indication for liver transplant in 2019, and the fastest increasing indication. In 2019, NASH was the leading indication for liver transplantation among women without HCC.

Hepatitis B virus (HBV) carries a large global burden. Efforts abound to decrease the burden, which necessitates reporting of patient-reported outcomes (PROs). We aimed to develop and validate an HBV-specific PRO instrument using the Chronic Liver Disease Questionnaire (CLDQ). Data were obtained from patients enrolled in our HBV registries who completed the CLDQ, Short Form-36 (SF-36) and FACIT-F. The sample was split randomly 1:1 into training and testing groups. A standard PRO instrument validation pipeline was used to develop and validate the new CLDQ-HBV instrument. HBV patients (n = 1,339) were 48 ± 13 years old, 60% male, 8% cirrhosis, with 53% receiving oral antivirals (OAV). After reduction of 10 redundant items, exploratory factor analysis for the remaining 19 items found 95% of variance was explained by five factors-emotional function, fatigue, systemic symptoms, worry and sleep. Good-to-excellent internal consistency was found: Cronbach's alphas 0.70-0.90 and item-to-own-domain correlations >0.50 for 18/19 items. Known-group validity tests discriminated between HBV patients with and without cirrhosis, with FIB-4 ≥ 3.25 vs <3.25, with and without history of depression or clinically overt fatigue (all p < 0.0001), and treatment (all p < 0.05, all but one <0.0001). After 48-week follow-up, HBV patients receiving OAV (N = 144) with ≥2.7 log 10/mL decline in HBV viral load experienced significant improvements in fatigue, worry and total CLDQ-HBV scores (p < 0.05). The newly developed CLDQ-HBV is a short, disease-specific PRO instrument for HBV patients which was developed and validated using large data set and an established methodology showing excellent psychometric characteristics.

BACKGROUND: The causative relationship between the clearance of infections and long-term, health-related quality-of-life (HRQL) improvements in patients with hepatitis C virus (HCV) has been generally accepted. The aim of this study was to assess long-term HRQL trends in HCV patients who did not achieve sustained virologic responses (SVRs) after treatment with direct-acting antivirals. METHODS: HCV patients who completed treatment in clinical trials and did not achieve SVRs were enrolled in a long-term registry (#NCT01457768). HRQL scores were prospectively collected using the short form-36 instrument (8 HRQL domains and 2 summary scores). RESULTS: There were 242 patients included: they had a median age of 54 years (standard deviation ± 8 years), 85% were male, and 38% had cirrhosis. Before treatment, patients' HRQL scores were similar to the general population norms (all 1-sided P > 0.05), but were followed by significant decreases by the end of treatment (-3.4 to -6.2 points; P < .05 for 5/8 HRQL domains and mental summary). By the time subjects entered the registry, all but 1 of the mean HRQL scores had returned to their pretreatment levels (P > .05). During subsequent periods in the registry, patients experienced further HRQL decrements: up to -9.2 points (P < .05 for all HRQL domains) at Week 24 and up to -8.3 points (P < .05 for 5/8 HRQL domains) at Week 48. Although these HRQL decrements were observed regardless of cirrhosis status, they were more pronounced in patients with cirrhosis (P < .05 for 3/8 HRQL domains). CONCLUSIONS: Patients who did not achieve an SVR after treatment experienced worsening HRQL scores in long-term follow-ups. Retreatment of these patients will be important not only to improve their clinical outcomes, but also their quality of life.

BACKGROUND & AIMS: Patients with hepatitis C virus (HCV) infections who achieve a sustained virologic response (SVR) to treatment have improved patient-reported outcomes (PROs). We compared post-treatment PRO scores between patients with chronic HCV infection who did and did not achieve an SVR to treatment. METHODS: Patients who completed treatment in clinical trials were enrolled in 2 registries, depending on the treatment outcome (NCT01457755, NCT01457768), from 2016 to 2017 in 17 countries in North America, Europe, and the Asia-Pacific region. PRO scores (scale, 0-100) were collected at pretreatment (baseline); the last day of treatment; the post-treatment week 12 follow-up visit (in patients with SVR only); the registry baseline; and on registry weeks 12, 24, 36, 48, and 96 (the non-SVR registry) or every 24 weeks until week 96 (SVR registry), using the Short Form-36 (SF-36) instrument. RESULTS: Our analysis included 4234 patients with an SVR and 242 without an SVR from whom pretreatment PRO data were available (mean age, 54 ± 10 y; 63% male; 65% enrolled in the United States; 17% with cirrhosis; 12% with human immunodeficiency virus co-infection). Upon registry enrollment, patients with an SVR had significant increases in all PRO scores compared with pretreatment baseline levels (all P < .05). Patients without an SVR had mean reductions of 9.2 points or less in PRO scores while followed up on the registry (P < .05 for 4-8 of 8 PRO domains measured by the SF-36). In contrast, patients with an SVR had sustained increases in PRO scores (mean increase, ≤7.0 points) while on the registry. In multivariate analysis, achieving an SVR was associated independently with superior scores in all SF-36 domains at all registry time points (ß, +4.8 to +15.9 points, all P ≤ .01). CONCLUSIONS: In a follow-up analysis of participants in clinical trials, we found that those with an SVR to treatment for HCV infection had significant increases in well-being, based on PRO scores. Patients without an SVR had decreasing PRO scores over the follow-up period.

Nonalcoholic steatohepatitis (NASH) is the progressive form of nonalcoholic fatty liver disease. Our aim was to estimate the total economic burden of NASH and advanced NASH in the United States. We constructed lifetime Markov models for all stages of NASH and a separate model to specifically identify the increased burden of advanced NASH (fibrosis stage >3). The models comprised patients aged 18+, who moved through seven different health states. We used a lifetime horizon with 1-year cycles for each transition. Cohort size was estimated using US population data, and prevalence and incidence rates were obtained from the literature. Transition probabilities between states were derived from meta-analyses. Costs included inpatient, outpatient, professional services, emergency department, and drug costs, which were obtained from the Center for Medicare and Medicaid Services Fee Schedule 2017 and published data. All future costs were discounted at an annual rate of 3%. Our models estimated that there are 6.65 million adults (18+ years old) with NASH in the United States and that there were 232,000 incident cases in 2017. Lifetime costs of all NASH patients in the United States in 2017 will be $222.6 billion, and the cost of the advanced NASH population will be $95.4 billion. Conclusion: NASH, especially advanced NASH, is associated with high lifetime economic burden; in the absence of treatment, the total direct costs of illness for these patients will continue to grow, and these costs would be even greater if the societal costs are included.

Primary biliary cholangitis (PBC) is a disease of small bile ducts, which can lead to morbidity and mortality. Our aim was to assess recent trends in mortality and healthcare use of PBC patients in the Medicare program. Data from Medicare beneficiaries between 2005 and 2015 (5% random samples) were used. The diagnosis of PBC was established with International Classification of Diseases-9 code 571.6 used for both primary and secondary diagnoses. Mortality was assessed by Medicare-linked death registry. Healthcare use included episodes of care, length of stay, and total charges/payments. Independent predictors of outcomes were evaluated in multiple generalized linear or logistic regression models. The study cohort included a total of 6,375 inpatient/outpatient Medicare beneficiaries (mean age 69.8 years, 17% male, 88% white, and 18% with disability). Over the study period, 1-year mortality remained stable (9.1% to 14.3%, P = 0.11). Independent predictors of 1-year mortality were older age, male gender, black race, the presence of ascites, encephalopathy, hepatocellular carcinoma, and higher Charlson score. Outpatient total yearly charges and payments per beneficiary with PBC increased from $3,065 and $777 (2005) to $5,773 and $967 (2014), respectively. Similarly, inpatient total yearly charges and payments per beneficiary with PBC increased from $59,765 and $19,406 (2007), to $98,941 and $27,948 (2013), respectively (P < 0.05). The presence of ascites, portal hypertension, and higher Charlson score were independent predictors of higher payments for both inpatient and outpatient resource use, and the presence of hepatic encephalopathy was an additional predictor of higher inpatient resource use (all P < 0.02). Conclusion: The prevalence of PBC among the Medicare beneficiaries has increased. Despite stable mortality rates, resource use for Medicare patients with PBC continues to rise.

BACKGROUND & AIMS: Currently, standard of care (SOC) treatment for NASH is limited to lifestyle modifications. Drug regimens are being evaluated currently. We assessed the impact of a short-term hypothetical treatment on clinical outcomes of NASH. METHODS: Markov models estimated differences in outcomes between SOC and 2 hypothetical NASH treatments (A and B). We modelled 10 000 50-year-old biopsy-proven NASH patients over lifetime horizon. Health states included NASH with fibrosis (F1-F3), cirrhosis, hepatocellular carcinoma, liver transplant and mortality. Fibrosis Regression Factor (FRF) variable modelled the probability of 1-3 stage fibrosis improvement with treatment. Annual probability of treatment (ATP) ranged from 10%-70%. Treatment success was defined as regression to fibrosis, whereas failure was defined as progression to stages beyond cirrhosis. In treatment-A, successful treatment was followed by a maintenance regimen which stopped disease progression. After a successful treatment-B, patients remained at risk of disease progression. Differences in outcomes were calculated between both treatments and SOC models. We conducted a probabilistic sensitivity analysis. RESULTS: At 10% to 70% ATP, treatment-A averts 353 to 782 liver transplants and 1277 to 2381 liver-related deaths relative to SOC. Treatment-B averts 129 to 437 liver transplants and 386 to 1043 liver-related deaths. Sensitivity analysis shows our model is robust in estimating liver-related mortality and LTs averted, but is sensitive when estimating QALYs gained. CONCLUSIONS: With a small annual probability of treatment and FRF = 1, a 2-year treatment followed by maintenance of histologic improvement for patients would be highly beneficial relative to short-term treatment alone.

GOALS: The main purpose of this study was to assess the recent trends in mortality and health care utilization of hepatocellular carcinoma (HCC) among Medicare population in the United States. BACKGROUND: The incidence of HCC is increasing in the United States. MATERIALS AND METHODS: Data were obtained for a sample of Medicare beneficiary from 2005 to 2014. Diagnosis of HCC and etiology of liver disease were based on ICD-9 codes. Temporal trends in HCC rates, clinical, demographical and utilization parameters were analyzed by joinpoint regression model. RESULTS: Study cohort included 13,648 Medicare recipients with HCC (mean age: 70.0 y, 62.8% male and 76.0% white). Non-alcoholic fatty liver disease (NAFLD) was the most common cause of HCC in the inpatient (32.07%) and outpatient (20.22%) followed by hepatitis C virus (HCV) (19.2% and 9.75%, respectively). Between 2005 and 2014, HCC rate per 100,000 Medicare recipients increased from 46.3 to 62.8 [average annual percentage change (AAPC) =3.4%, P<0.001]. Rate of HCV-HCC increased from 6.18 to 16.54 (AAPC=11.8%, P<0.001) while the NAFLD-HCC increased from 9.32 to 13.61, P<0.001). Overall 1-year mortality decreased from 46.2% to 42.1% (AAPC=-1.7%, P=0.004). Total charges increased from $67,679 to $99,420 (AAPC=5.1%, P<0.001) for inpatients and from $11,933 to $32,084 (P<0.001) for outpatients. On comparison of patients with hepatitis B virus-HCC, those with NAFLD-HCC (odds ratio: 1.87, P<0.001) had higher risk of mortality. On comparison of patients with hepatitis B virus-HCC, those with HCV-HCC had higher charges (percent change: 24.33%, 95% confidence interval: 1.02%-53.02%, P=0.040). CONCLUSIONS: Although HCC rates are increasing, the overall mortality is decreasing. NAFLD is the most important cause of HCC and an independent predictor of HCC in the outpatient setting for Medicare patients with HCC.

BACKGROUND & AIMS: The chronic liver disease questionnaire for nonalcoholic steatohepatitis (CLDQ-NASH) was developed in a systematic manner for assessment of patient-reported outcomes. This instrument collects data on 36 items grouped into 6 domains: abdominal symptoms, activity/energy, emotional health, fatigue, systemic symptoms, and worry. We aimed to validate the CLDQ-NASH in a large group of patients with NASH. METHODS: We collected data from patients with biopsy-proven NASH enrolled in 2 international phase 3 trials of selonsertib (NCT03053050 and NCT03053063). Our final analysis comprised 1667 patients who completed the CLDQ-NASH (age, 58 ± 9 y; 40% male; 52% with cirrhosis; and 69% with type 2 diabetes). The CLDQ-NASH was administered before treatment initiation. A standard patient-reported outcome instrument validation pipeline with internal consistency and validity assessment was applied. RESULTS: The domains of CLDQ-NASH showed good to excellent internal consistency: the Cronbach's α values were 0.80 to 0.94 and item-to-own-domain correlations were greater than 0.50 for 33 of 36 items. All items correlated to the greatest extent with their own domains (discriminant validity). Known-group validity tests indicated that the instrument consistently discriminated between patients with NASH based on the presence of cirrhosis (vs bridging fibrosis; all but 1 P value < .02), obesity (all but 1 P value < .001), psychiatric comorbidities (all P values < .0001), fatigue (all P values < .001), and type 2 diabetes (all but 1 P value < .01). Of the CLDQ-NASH domains, the highest correlated domains with the Short Form-36 were as follows: physical functioning for activity (rho = 0.70), mental health for emotional (rho = 0.72), vitality for fatigue (rho = 0.75), and body pain for systemic (rho = 0.72) (all P values < .0001). In contrast, the domains of abdominal and worry, which are disease-specific, did not correlate with the domains in the Short Form-36 (all rho ≤ 0.50). CONCLUSIONS: We validated the CLDQ-NASH by an analysis of data from 1667 patients with biopsy-proven NASH enrolled in phase 3 trials, observing excellent psychometric characteristics of the instrument.

Worldwide, viral hepatitis remains the most common cause of chronic liver disease.1 In this context, hepatitis B virus (HBV) infection and its complications are responsible for a tremendous clinical burden related to cirrhosis and hepatocellular carcinoma.1 In contrast, long-term HBV suppression can improve hepatic fibrosis and clinical outcomes.2.

BACKGROUND & AIMS: Although hepatitis B and C have been the main drivers of hepatocellular carcinoma (HCC), nonalcoholic steatohepatitis (NASH) has recently become an important cause of HCC. The aim of this study was to assess the causes of HCC among liver transplant (LT) candidates in the United States. METHODS: The Scientific Registry of Transplant Recipients (2002-2016) was used to estimate the trends in prevalence of HCC in LT candidates with the most common types of chronic liver disease: alcoholic liver disease (ALD), chronic hepatitis B (CHB), chronic hepatitis C, and NASH. RESULTS: 158,347 adult LT candidates were included. Of these, 26,121 (16.5%) had HCC; this proportion increased from 6.4% (2002) to 23.0% (2016) (trend P < .0001). Over the study period, CHC remained the most common etiology for HCC (65%). The proportions of HCC accounted for by CHC and ALD remained stable (both trend P > .10), the proportion of CHB decreased 3.1-fold (P < .0001), while the proportion of NASH in HCC increased 7.7-fold (from 2.1% to 16.2%; P < .0001). Furthermore, since 2002, the prevalence of HCC in LT candidates with NASH increased 11.8-fold, while this rate increased 6.0-fold in CHB, 3.4-fold in ALD, and 2.3-fold in CHC (all P < .0001); the increasing trend in NASH was steeper than that for any other etiology (P < .0001 in a trend regression model). The proportion of LT candidates with HCC who ultimately received a transplant or died while waiting did not differ between etiologies (P > .05). CONCLUSIONS: Nonalcoholic steatohepatitis is the most rapidly growing cause of HCC among US patients listed for liver transplantation.

BACKGROUND & AIMS: Non-alcoholic and alcohol-related fatty liver disease are overlapping diseases in which metabolic syndrome and alcohol consumption each contribute to progressive liver disease. We aimed to assess the effects of alcohol consumption and metabolic syndrome on mortality in individuals with fatty liver. METHODS: We searched the National Health and Nutrition and Examination Survey III for adults (20-74 years old) with hepatic steatosis, detected by ultrasound, for whom mortality and follow-up data were available. We collected data from the alcohol use questionnaire (self-reported number of days a participant drank alcohol; the number of drinks [10 g alcohol] per day on a drinking day; the number of days the participant had 5 or more drinks) and calculated the average amount of alcohol consumption in drinks/day for each participant during the year preceding enrollment. Excessive alcohol consumption for men was >3 drinks/day and for women was >1.5 drinks/day. We also collected clinical data, and mortality data were obtained from the National Death Index. Demographic and clinical parameters were compared among consumption groups using the χ2 test for independence or survey regression models. We used Cox proportional hazard models to identify independent predictors of all-cause and cause-specific mortality. RESULTS: The study cohort included 4264 individuals with hepatic steatosis (mean age, 45.9 years; 51% male; 76% white; 46% with metabolic syndrome; 6.2% with excessive alcohol use). There was no significant difference in mean age between individuals with vs without excessive alcohol consumption (P=.65). However, overall mortality was significantly higher among participants with excessive alcohol consumption (32.2%) vs participants with non-excessive alcohol use (22.2%) after mean 20 years of follow up (P=.003), as well as after 5 years of follow up. In multivariate analysis, the presence of metabolic syndrome (adjusted hazard ratio [aHR], 1.43; 95% CI, 1.12-1.83) and excessive alcohol consumption (aHR, 1.79; 95% CI, 1.21-2.66) were independently associated with an increased risk of death in individuals with hepatic steatosis; any lower average amount of alcohol consumption was not associated with mortality (all P>.60). In a subgroup analysis, the association of excessive alcohol use with mortality was significant in individuals with metabolic syndrome (aHR, 2.46; 95% CI, 1.40-4.32) but not without it (P=.74). CONCLUSION: In review of data from the National Health and Nutrition and Examination Survey III, we associated alcohol consumption with increased mortality in participants with fatty liver and metabolic syndrome. These findings indicate an overlap between non-alcoholic and alcohol-related fatty liver disease.

INTRODUCTION: Although there is substantial evidence suggesting poor health-related quality of life (HRQL) in patients with chronic hepatitis C (CHC), similar data in nonalcoholic steatohepatitis (NASH) have not been fully assessed. The aim is to compare HRQL scores in patients with CHC to those with NASH. METHODS: Matched patients with advanced fibrosis (bridging fibrosis and compensated cirrhosis) due to CHC and NASH completed Short Form-36 (SF-36) questionnaire, Chronic Liver Disease Questionnaire (CLDQ), and Work Productivity and Activity Instrument questionnaire. RESULTS: We included 1,338 patients with NASH with advanced fibrosis (mean age 57.2 years, 47% men, 55% cirrhosis) and 1,338 matched patients with CHC. Patients with CHC and NASH had similar rates of employment and psychiatric disorders (P > 0.05). As expected, patients with NASH had higher body mass index (mean 33.7 vs 27.6) and more type 2 diabetes (74% vs 16%) (all P < 0.01). Patients with NASH had significantly lower HRQL scores related to physical health: Physical Functioning, Bodily Pain, General Health, Vitality, Physical Summary of SF-36, and Fatigue of CLDQ (P < 0.02). By contrast, patients with CHC had a lower Mental Health score of SF-36 and Emotional score of CLDQ and reported greater impairment in daily activities as measured by the Work Productivity and Activity Instrument questionnaire (P < 0.002). In multivariate analysis, after adjustment for demographic parameters, cirrhosis, and history of psychiatric disorders, having NASH was associated with lower physical HRQL scores and higher mental health-related scores (P < 0.05). DISCUSSION: Patients with NASH and advanced fibrosis have more impairment of their physical health-related scores than patients with CHC with advanced fibrosis. These data should dispel the misconception that NASH is an asymptomatic disease with little negative impact on patients' well-being.
