RESUMO
INTRODUCTION: This study investigates the applicability of the new metabolic dysfunction-associated steatotic liver disease (MASLD) nomenclature to the real-world TARGET-NASH US adult cohort. METHODS: The new MASLD/metabolic steatohepatitis nomenclature was applied to patients enrolled with pragmatic diagnoses of nonalcoholic fatty liver and nonalcoholic steatohepatitis (NASH), and NASH cirrhosis and concordance were determined between the definitions. RESULTS: Approximately 99% of TARGET-NASH participants met the new MASLD diagnostic criteria. Approximately 1,484/1,541 (96.3%, kappa 0.974) nonalcoholic fatty liver patients (metabolic dysfunction-associated steatotic liver), 2,195/2,201 (99.7%, kappa 0.998) NASH patients (metabolic steatohepatitis), and 1,999/2,003 (99.8%, kappa 0.999) NASH cirrhosis patients met the new criteria. DISCUSSION: The new MASLD nomenclature is highly concordant with the previous TARGET-NASH pragmatic definitions.

BACKGROUND & AIMS: There is an unmet need to validate simple and easily available methods that can be used in routine practice to identify those at risk of adverse outcomes from nonalcoholic fatty liver disease (NAFLD). A retrospective-prospective analysis of NAFLD patients enrolled in a longitudinal noninterventional study (TARGET-NASH) was performed to validate the prognostic utility of the following risk-categories: (A) Fibrosis-4 (FIB-4) <1.3 and/or liver-stiffness measurement (LSM) measured by Fibroscan <8 kp, (B) FIB-4 1.31â2.6 and/or LSM 8.1-12.5 kp, and (C) FIB-4 >2.6 and/or LSM >12.5 kp. METHODS: Those in class A with aspartate transaminase:alanine transaminase ratio >1 or platelets <150,000/mm3, or class B with aspartate transaminase:alanine transaminase ratio >1 or platelets <150,000/mm3 were upstaged by one class. Fine-Gray competing risk analyses were performed for all outcomes. RESULTS: A total of 2523 individuals (class A = 555, B = 879, C = 1089) were followed for a median duration of 3.74 years. Adverse outcomes increased from class A to C in all-cause mortality (0.07 vs 0.3 vs 2.5/100 person-years [PY], hazard ratio [HR], 3.0 and 16.3 class B and C vs A), liver-associated clinical events (0.2 vs 1 vs 8/100 PY, HR, 4.3 and 36.6 B and C vs A), major adverse cardiovascular events (0.69 vs 0.87 vs 2.02/100 PY, HR, 0.78 and 1.55 B and C vs A), hepatocellular carcinoma (0 vs 0.09 vs 0.88/100 PY, HR, 8.32 C vs B), and chronic kidney disease (1.24 vs 2.48 vs 3.51/100 PY). Those who were upstaged had outcome rates similar to the lower class defined by their FIB-4. CONCLUSIONS: These data support a FIB-4-based risk-stratification of NAFLD that can be used in routine clinical practice. CLINICALTRIALS: gov Identifier: NCT02815891.

BACKGROUND AND AIMS: Patients with primary biliary cholangitis (PBC) often suffer with pruritus. We describe the impact of pruritus on quality of life and how it is managed in a real-world cohort. METHODS: TARGET-PBC is a longitudinal observational cohort of patients with PBC across the USA. Data include information from medical records for three years prior to the date of consent up to 5 years of follow-up. Enrolled patients were asked to complete patient-reported outcome surveys: PBC-40, 5-D itch, and the PROMIS fatigue survey. Kruskal-Wallis tests were used to compare differences in symptoms between groups. RESULTS: A total of 211 patients with completed PRO surveys were included in the current study. PRO respondents were compared with non-respondents in the TARGET-PBC population and were broadly similar. Pruritus was reported in 170 patients (81%), with those reporting clinically significant pruritus (30%) scoring worse across each domain of the PBC-40 and 5-D itch, more frequently having cirrhosis, and having significantly greater levels of fatigue. Patients reporting clinically significant pruritus were more likely to receive treatment, but 33% had never received treatment (no itch = 43.9%, mild itch = 38.3%). CONCLUSIONS: The prevalence of pruritus was high in this population, and those reporting clinically significant pruritus had a higher likelihood of having advanced disease and worse quality of life. However, this study found that pruritus in PBC is under-treated. This may be due in part to ineffectiveness of current treatments, poor tolerance, or the lack of FDA-approved medications for pruritus.

Background: Pediatric non-alcoholic fatty liver disease (NAFLD) is a major public health concern. Aminotransferase (ALT) is frequently used for screening and monitoring, but few studies have reported typical patterns of ALT elevation in children. Methods: TARGET-NASH is a real-world longitudinal observational cohort of patients with NAFLD receiving care across the United States. Analyses included children enrolled between 1 August 2016, and 12 October 2020, with at least one ALT measurement after enrollment. Peak ALT was based on the first and last available record and categorized into clinical cut points: <70 IU/L, >70−<250 IU/L, and >250 IU/L. A chi-squared test was used to compare differences in proportions, and a Kruskal−Wallis test was used to compare the medians and distributions of continuous responses. Results: Analyses included 660 children with a median age of 13 years. Of the 660, a total of 187 had undergone a biopsy and were more likely to be Hispanic or Latino (67% vs. 57%, p = 0.02) and to have cirrhosis (10% vs. 1%, p < 0.001). The highest ALT scores ranged from 28 U/L to 929 U/L; however, these scores varied across time. The prevalence of cirrhosis or any liver fibrosis stage was most common among children with a peak ALT > 70 U/L. Conclusions: Large variability was seen in ALT among children, including many values > 250 U/L. Higher levels of ALT were associated with increased prevalence of comorbidities and more advanced stages of NAFLD. These findings support an increased need for therapeutics and disease severity assessment in children with peak ALT > 70 U/L.
RESUMO
Patients with nonalcoholic fatty liver disease (NAFLD) are at an increased risk of cardiovascular disease. Hydoxy-3-methyglutaryl-coenzyme reductase inhibitors, statins, reduce the risk of cardiovascular events.1 Studies have shown that statins are safe among patients with liver disease, including those with compensated cirrhosis,2 and their use is associated with lower mortality, hepatic decompensation, and possibly hepatocellular carcinoma.3,4 Despite these data, statins are under prescribed among patients with liver disease due to concerns about hepatotoxicity.5 This study aimed to assess prevalence and patient factors associated with indicated statin use in patients with NAFLD in a real-world cohort.

BACKGROUND: Patients hospitalized for coronavirus disease 2019 (COVID-19) may experience complications following hospitalization and require readmission. In this analysis, we estimated the rate and risk factors associated with COVID-19-related readmission and inpatient mortality. METHODS: In this retrospective cohort study, we used deidentified chargemaster data from 297 hospitals across 40 US states on patients hospitalized with COVID-19 from 15 February 2020 through 9 June 2020. Demographics, comorbidities, acute conditions, and clinical characteristics of first hospitalization are summarized. Multivariable logistic regression was used to measure risk factor associations with 30-day readmission and in-hospital mortality. RESULTS: Among 29 659 patients, 1070 (3.6%) were readmitted. Readmitted patients were more likely to have diabetes, hypertension, cardiovascular disease (CVD), or chronic kidney disease (CKD) vs those not readmitted (Pâ <â .0001) and to present on first admission with acute kidney injury (15.6% vs 9.2%), congestive heart failure (6.4% vs 2.4%), or cardiomyopathy (2.1% vs 0.8%) (Pâ <â .0001). Higher odds of readmission were observed in patients aged >60 vs 18-40 years (odds ratio [OR], 1.92; 95% confidence interval [CI], 1.48-2.50) and those admitted in the Northeast vs West (OR, 1.43; 95% CI, 1.14-1.79) or South (OR, 1.28; 95% CI, 1.11-1.49). Comorbidities including diabetes (OR, 1.34; 95% CI, 1.12-1.60), CVD (OR, 1.46; 95% CI, 1.23-1.72), CKD stage 1-5 (OR, 1.51; 95% CI, 1.25-1.81), and CKD stage 5 (OR, 2.27; 95% CI, 1.81-2.86) were associated with higher odds of readmission; 12.3% of readmitted patients died during second hospitalization. CONCLUSIONS: Among this large US population of patients hospitalized with COVID-19, readmission was associated with certain comorbidities and acute conditions during first hospitalization. These findings may inform strategies to mitigate risks of readmission due to COVID-19 complications.

BACKGROUND: Nucleos(t)ide analogues, with a proven record of safety and efficacy, have been the therapy of choice for over a decade for the treatment of chronic hepatitis B. The approval of tenofovir alafenamide (TAF) in 2016 provided an additional treatment option. AIMS: The aim of this study was to evaluate the characteristics and clinical outcomes of patients treated with TAF in usual clinical practice. METHODS: Retrospective data from electronic health records was obtained from those enrolled in TARGET-HBV, a longitudinal observational cohort study of patients with chronic hepatitis B managed according to local practice standards at community and academic medical centers throughout the U.S. RESULTS: Of 500 patients enrolled, most were male (66%) and of Asian race (66%) with median age of 55 years. Cirrhosis was evident in 15%. Most patients (82%) had switched to TAF after treatment with other antivirals. The perceived safety profile of TAF was cited as the primary reason for changing therapy (32%). TAF was well tolerated and only 4 patients discontinued therapy due to adverse event during a median duration of TAF dosing of 74 weeks. Among those with paired laboratory data 12-18 months after switching to TAF, biochemical response and HBV DNA suppression was maintained. Most patients had normal renal function which was essentially unchanged throughout follow-up. CONCLUSIONS: TAF is frequently utilized in routine clinical practice due to the perception of its improved safety profile. The current study supports the growing body of evidence regarding the safety and effectiveness of TAF.

BACKGROUND: Patients with non-alcoholic steatohepatitis (NASH) and fibrosis stage ≥2 comprise a target population for pharmacotherapy. Liver biopsy, the reference standard for identifying this population, requires complete and accurate assessment of steatohepatitis and fibrosis. Aims To investigate the completeness of real-world NASH-related pathology reports, assess concordance between site pathologists and central expert interpretation of the histologic elements of NASH, and determine concordance between biopsy-diagnosed NASH and a pragmatic clinical definition of NASH. METHODS: Liver pathology reports from 222 patients across 38 TARGET-NASH sites were analysed for documentation of the histologic features of NASH. Biopsy slides were over-read by a blinded central expert pathologist. Concordance of histologic scores and interpretation was assessed. Histologic concordance with a clinical definition of NASH was determined. TARGET-NASH clinically defined NASH: elevated ALT, hepatic steatosis on biopsy or imaging and ≥1 of the following: BMI ≥30 kg/m2 , type 2 diabetes mellitus and dyslipidaemia. RESULTS: Documentation of steatosis, lobular inflammation, portal inflammation and ballooning were missing from 21%, 35%, 46% and 40% of reports, respectively. There was slight-to-fair concordance (weighted kappa 0.01-0.35) between site and central pathologists for inflammatory features, and moderate concordance (weighted kappa 0.56-0.57) for fibrosis staging. Clinical definition of NASH was 75%-91% concordant (94%-95% sensitive) with biopsy-diagnosed NASH. CONCLUSIONS: There is substantial variability in reporting and grading NASH and fibrosis staging in clinical practice. This heterogeneity may adversely impact patient assessment and translation of practice guidelines into reality. The TARGET-NASH pragmatic clinical definition may serve as a valuable tool to accurately identify NASH patients in clinical practice.

Much of the current data on nonalcoholic fatty liver disease (NAFLD) are derived from biopsy-based studies that may introduce ascertainment and selection bias. Selection of patients for liver biopsy has implications for clinical practice and the reported epidemiology of NAFLD. The aim of this study was to determine patient factors predictive of histologic versus empiric clinical diagnosis of NAFLD in real-world practice. Adults from TARGET-NASH were included in this study. Descriptive statistics are provided for the cohort and compare the characteristics of histologic NAFLD versus patients with clinically diagnosed NAFLD, followed by logistic regression and machine-learning models to describe predictors of liver biopsy. The records of 3,474 subjects were analyzed; median age was 59 years, 59% were female, 75% were White, and median body mass index was 32 kg/m2. Using histologic and/or clinical criteria, a diagnosis of nonalcoholic steatohepatitis was made in 37%, and cirrhosis in 33%. Comorbid conditions included cardiovascular disease (19%), mental health diagnoses (49%), and osteoarthritis (10%). Predictors of a biopsy diagnosis included White race, female sex, diabetes, and elevated alanine aminotransferase (ALT). ALT increased the odds of liver biopsy by 14% per 10-point rise. Machine-learning analyses showed non-White patients with ALT <69 had only a 0.06 probability of undergoing liver biopsy. ALT was the dominant variable that determined liver biopsy. Conclusions: In this real-world cohort of patients with NAFLD, two-thirds of patients did not have a liver biopsy. These patients were more likely to be non-White, older, with a normal ALT, showing potential gaps in or knowledge about this population.
RESUMO
Real-world evidence includes all health-related information, such as electronic health records, insurance claims, pharmacy records and wearables that are obtained outside of clinical trials. These data can provide critical insights into the natural history of disease and evaluate the safety and effectiveness of treatment regimens used in clinical practice. Real-world data have been applied to varying degrees by global regulatory agencies to inform and expedite many phases of drug development and help refine the use of therapeutic regimens after marketing, especially in populations that are under-represented in registration trials. For the management of hepatocellular carcinoma, early detection provides the best chance for curative therapies, whose success has been evaluated in numerous cohorts. The availability of novel systemic therapies, including kinase inhibitors and immunotherapies, has provided new treatment options and improved survival in patients with advanced stage hepatocellular carcinoma. Real-world longitudinal observational studies can help understand the long-term safety and effectiveness of these agents.

This study describes the design of the TARGET-hepatocellular carcinoma (HCC) cohort and descriptive characteristics of the patient population at diagnosis among those who were enrolled in the cohort across academic and community clinical centers. TARGET-HCC is a 5-year, longitudinal, observational cohort of patients with HCC receiving care in usual clinical practice. Redacted clinical information, obtained from medical records, captures the natural history and management of the disease, including the safety and efficacy of treatment interventions used in usual clinical practice. Patients can complete patient-reported outcome measures and provide biological specimens for future translational studies. The TARGET-HCC study includes adults with histologic, cytologic, or radiologic diagnosis of HCC from academic and community centers in both the United States and Europe. A total of 1,841 participants were enrolled between January 9, 2017, and July 23, 2019, at 67 sites in the United States and Europe. To date, the most common liver disease etiology in the cohort continues to be hepatitis C, although nearly half had a nonviral etiology, including alcohol-related liver disease or nonalcoholic steatohepatitis. Most included patients were diagnosed at an early stage (Barcelona Clinic Liver Cancer Stage [BCLC] 0/A), but only approximately one third underwent curative treatment. Systemic therapy has been used in 7.3% of enrolled patients, including 45.7% of those with BCLC stage C tumors. Conclusion: Overall, the TARGET-HCC cohort allows for the assessment of patient characteristics and investigation of new treatment paradigms and sequencing with existing agents as well as novel regimens for HCC.

BACKGROUND: As coronavirus disease 2019 (COVID-19) disseminates throughout the United States, a better understanding of the patient characteristics associated with hospitalization, morbidity, and mortality in diverse geographic regions is essential. METHODS: Hospital chargemaster data on adult patients with COVID-19 admitted to 245 hospitals across 38 states between 15 February and 20 April 2020 were assessed. The clinical course from admission, through hospitalization, and to discharge or death was analyzed. RESULTS: A total of 11 721 patients were included (majority were >60 years of age [59.9%] and male [53.4%]). Comorbidities included hypertension (46.7%), diabetes (27.8%), cardiovascular disease (18.6%), obesity (16.1%), and chronic kidney disease (12.2%). Mechanical ventilation was required by 1967 patients (16.8%). Mortality among hospitalized patients was 21.4% and increased to 70.5% among those on mechanical ventilation. Male sex, older age, obesity, geographic region, and the presence of chronic kidney disease or a preexisting cardiovascular disease were associated with increased odds of mechanical ventilation. All aforementioned risk factors, with the exception of obesity, were associated with increased odds of death (all P values < .001). Many patients received investigational medications for treatment of COVID-19, including 48 patients on remdesivir and 4232 on hydroxychloroquine. CONCLUSIONS: This large observational cohort describes the clinical course and identifies factors associated with the outcomes of hospitalized patients with COVID-19 across the United States. These data can inform strategies to prioritize prevention and treatment for this disease.
