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 (p0.05). 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 (p0.05). 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) (p0.05). 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 p0.10). 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.

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 0.05). In conclusion, hepatitis C patients seen in the real-world practices have PRO impairment driven by fatigue and psychiatric comorbidities.

Entecavir (ETV) and tenofovir disoproxil fumarate (TDF) are the first-line treatment agents for chronic hepatitis B virus (HBV). Recently, whether the degree to which the risk of hepatocellular carcinoma (HCC) may be reduced by ETV vs TDF has been debated. We compared the incidence of HCC among treatment-naïve patients receiving TDF vs ETV in the United States.From a large administrative medical claims database of commercially insured patients, we identified 166,933 adults with a diagnosis of chronic hepatitis B and a minimum of 12 months of prior enrolment, of whom 3934 and 6127 initiated ETV and TDF respectively. Fine-Gray hazard regression models incorporating treatment propensity scores (PS) were used to estimate the risk of HCC incidence associated with TDF vs ETV; variables considered for adjustment included demographic characteristics, concomitant medication use and baseline comorbidities, as well as competing events including liver transplantation and medication changes.After PS weighting, the TDF and ETV groups were well-matched. During the follow-up, 90 patients developed HCC, including 50 receiving ETV and 40 receiving TDF, giving rise to crude incidence rates of 0.62 per 100 person-years (PY) and 0.30 per 100 PY respectively. In PS-weighted, multivariable analysis, TDF was associated with a subdistribution hazard ratio for HCC of 0.58 (95% confidence interval [CI]: 0.38-0.89) compared to ETV. Results were similar when patients ≥40 years and men and women were analysed separately.Among commercially insured, treatment-naïve patients with chronic hepatitis B in the United States, treatment with TDF was associated with significantly lower risk of HCC than ETV.

Hepatitis B virus (HBV) infection causes hepatocellular carcinoma but its association with other cancers is not well established. We compared age-adjusted incidence of primary cancers among 5773 HBV-infected persons with US cancer registries during 2006–2018. Compared with the US population, substantially higher incidence among HBV-infected persons was observed for hepatocellular carcinoma (standardized rate ratio [SRR], 30.79), gastric (SRR, 7.95), neuroendocrine (SRR, 5.88), cholangiocarcinoma (SRR, 4.62), and ovarian (SRR, 3.72) cancers, and non-Hodgkin lymphoma (SRR, 2.52). Clinicians should be aware of a heightened potential for certain nonhepatic malignancies among hepatitis B patients, as earlier diagnosis favors improved survival.

We investigated factors associated with rates of recommended monitoring of chronic hepatitis B (HBV) patients for viral DNA and alanine aminotransferase (ALT), and initiation of antiviral treatment among eligible patients, in a US cohort of patients under routine care. Patients were categorised by treatment indication: definite, equivocal or ineligible. Baseline covariates included demographics, clinical characteristics and specialist care status. 'Recommended monitoring' was defined ≥1 ALT or HBV DNA test per year. Logit models, univariate then multivariable, were used to evaluate factors associated with monitoring and treatment. Among 3,830 patients, treatment was received by 67.5% (788/1168 patients) in the 'definite' category, and 34.1% (208/610 patients) in the 'equivocal' category, of whom 109 moved up to 'definite' status at some point during follow-up. Sex, age and specialist care were independently associated with receipt of treatment in 'definite' patients. Routine monitoring rates were high prior to treatment in 'definite/ treated' patients (ALT: 77%; DNA: 85%) but declined afterwards (ALT 63%; DNA 36%). Rates of monitoring were lower in 'definite/ untreated' patients (ALT: 48%; DNA: 32%). Among 'equivocal/ treated' patients, lower age and comorbidity scores were associated with receipt of treatment; ALT monitoring rates were similar before and after treatment initiation (41% and 46%, respectively), while rates of DNA monitoring declined (55% and 29%). Monitoring among 'treatment ineligible' patients was similar to those in the 'equivocal' and untreated 'definite' groups. A large proportion of US HBV patients under routine care did not receive recommended annual laboratory monitoring, especially after initiation of antiviral treatment, and nearly one-third of patients with 'definite' indications for antiviral therapy remained untreated.

Ursodeoxycholic acid (UDCA) remains the first-line therapy for primary biliary cholangitis (PBC); however, inadequate treatment response (ITR) is common. The UK-PBC Consortium developed the modified UDCA Response Score (m-URS) to predict ITR (using alkaline phosphatase [ALP] > 1.67 times the upper limit of normal [*ULN]) at 12 months post-UDCA initiation). Using data from the US-based Fibrotic Liver Disease Consortium, we assessed the m-URS in our multi-racial cohort. We then used a dynamic modeling approach to improve prediction accuracy. Using data collected at the time of UDCA initiation, we assessed the m-URS using the original formula; then, by calibrating coefficients to our data, we also assessed whether it remained accurate when using Paris II criteria for ITR. Next, we developed and validated a dynamic risk prediction model that included post-UDCA initiation laboratory data. Among 1578 patients (13% men; 8% African American, 9% Asian American/American Indian/Pacific Islander; 25% Hispanic), the rate of ITR was 27% using ALP > 1.67*ULN and 45% using Paris II criteria. M-URS accuracy was “very good” (AUROC = 0.87, sensitivity = 0.62, and specificity = 0.82) for ALP > 1.67*ULN and “moderate” (AUROC = 0.74, sensitivity = 0.57, and specificity = 0.70) for Paris II. Our dynamic model significantly improved accuracy for both definitions of ITR (ALP > 1.67*ULN: AUROC = 0.91; Paris II: AUROC = 0.81); specificity approached 100%. Roughly 9% of patients in our cohort were at the highest risk of ITR. Early identification of patients who will not respond to UDCA treatment using a dynamic prediction model based on longitudinal, repeated risk factor measurements may facilitate earlier introduction of adjuvant treatment.

Early reports suggest that alcohol misuse increased in 2020 as a result of the COVID-19 pandemic. Using retrospective data from Henry Ford Health System in Detroit MI-an area that experienced an early and severe COVID-19 outbreak-we investigated the impact of the pandemic on alcohol-related liver disease (ARLD) in the summer of 2020 compared with the same period in 2016-2019. Both the number of ARLD admissions and the proportion of total admissions represented by ARLD patients increased significantly in 2020 compared with previous years. The number of ARLD admissions as a proportion of all hospitalizations was 50% higher in 2020 than in 2016-2019 (0.31% vs 0.21%; P = .0013); by September 2020, the number of admissions was 66% higher than previous years. Despite racial and geographical disparities in direct and indirect COVID-related stressors across the Detroit metropolitan area, the demographic profile of ARLD patients did not change compared with previous years.

Introduction More than 70 million people are estimated to be infected with hepatitis C virus (HCV) globally. If left untreated, HCV infection can lead to complications such as extensive liver fibrosis, cirrhosis, and hepatocellular carcinoma (HCC). Evolution of treatments has resulted in highly effective and well-tolerated all-oral direct-acting antivirals. The pangenotypic regimen of glecaprevir/pibrentasvir is approved for treating HCV for patients without cirrhosis or with compensated cirrhosis (CC). Guidelines have evolved to simplify treatment to enable non-specialists to manage and treat HCV-infected patients. Simultaneously, such treatment algorithms provide guidance on the pretreatment identification of small subsets of patients who may require specialist treatment and long-term follow-up for advanced liver disease, including those at risk of developing HCC. This study describes the safety profile of glecaprevir/pibrentasvir in patients identified using previously described noninvasive laboratory measures who may be eligible for treatment by non-liver specialists. Methods This post hoc analysis of glecaprevir/pibrentasvir in patients, identified by noninvasive laboratory measures, intended to exclude patients with advanced liver disease and severe renal impairment, who can be managed within non-liver specialist settings. Patients were included from clinical trials and real-world studies of glecaprevir/pibrentasvir for HCV treatment. Baseline demographics, clinical characteristics, and safety assessments, including adverse events and laboratory abnormalities, were summarized. Results Data across these large-scale studies confirm that glecaprevir/pibrentasvir is well tolerated across different patient populations, with fewer than 0.1% of patients experiencing a serious adverse event related to treatment drugs, and few patients developing HCC during or after treatment. Conclusion The safety profile of glecaprevir/pibrentasvir enhances the confidence of non-liver specialists to treat the majority of HCV-infected patients, and provides an opportunity to expand the treater pool, potentially increasing diagnosis and treatment rates for HCV, contributing to elimination of HCV.

There are limited data examining the relationship between psychosocial factors and receipt of direct‐acting antiviral (DAA) treatment among patients with hepatitis C in large health care organizations in the United States. We therefore sought to determine whether such factors were associated with DAA initiation. We analyzed data from an extensive psychological, behavioral, and social survey (that incorporated several health‐related quality of life assessments) coupled with clinical data from electronic health records of patients with hepatitis C enrolled at four health care organizations during 2017‐2018. Of 2,681 patients invited, 1,051 (39.2%) responded to the survey; of 894 respondents eligible for analysis, 690 (77.2%) initiated DAAs. Mean follow‐up among respondents was 9.2 years. Compared with DAA recipients, nonrecipients had significantly poorer standardized scores for depression, anxiety, and life‐related stressors as well as poorer scores related to physical and mental function. Lower odds of DAA initiation in multivariable analysis (adjusted by age, race, sex, study site, payment provider, cirrhosis status, comorbidity status, and duration of follow‐up) included Black race (adjusted odds ratio [aOR], 0.59 vs. White race), perceived difficulty getting medical care in the preceding year (aOR, 0.48 vs. no difficulty), recent injection drug use (aOR, 0.11 vs. none), alcohol use disorder (aOR, 0.58 vs. no alcohol use disorder), severe depression (aOR, 0.42 vs. no depression), recent homelessness (aOR, 0.36 vs. no homelessness), and recent incarceration (aOR, 0.34 vs. no incarceration). Conclusion: In addition to racial differences, compared with respondents who initiated DAAs, those who did not were more likely to have several psychological, behavioral, and social impairments. Psychosocial barriers to DAA initiation among patients in care should also be addressed to reduce hepatitis C‐related morbidity and mortality., Even among persons with access to care, receipt of direct‐acting antiviral treatment for hepatitis C is suboptimal. We therefore conducted a detailed psychological, behavioral, and social survey among hepatitis C patients in care to determine whether such factors were associated with DAA initiation. Compared with respondents who initiated DAAs, those who did not were more likely to have several psychological, behavioral, and social impairments, suggesting that such factors should be addressed to reduce hepatitis C‐related morbidity and mortality.

We used data from the 11 US health systems in the FibrOtic Liver Disease Consortium to explore a combination of biochemical markers and electronic health record (EHR)-based diagnosis/procedure codes (DPCs) to identify the presence of cirrhosis in PBC patients.MethodsHistological fibrosis staging data were obtained from liver biopsies. Variables considered for the model included demographics (age, gender, race, ethnicity), total bilirubin, alkaline phosphatase, albumin, aspartate aminotransferase (AST) to platelet ratio index (APRI), Fibrosis 4 (FIB4) index, AST to alanine aminotransferase (ALT) ratio, and g100 DPCs associated with cirrhosis/decompensated cirrhosis, categorized into ten clusters. Using least absolute shrinkage and selection operator regression (LASSO), we derived and validated cutoffs for identifying cirrhosis.ResultsAmong 4328 PBC patients, 1350 (32%) had biopsy data; 121 (9%) were staged F4 (cirrhosis). DPC clusters (including codes related to cirrhosis and hepatocellular carcinoma diagnoses/procedures), Hispanic ethnicity, ALP, AST/ALT ratio, and total bilirubin were retained in the final model (AUROC=0.86 and 0.83 on learning and testing data, respectively); this model with two cutoffs divided patients into three categories (no cirrhosis, indeterminate, and cirrhosis) with specificities of 81.8% (for no cirrhosis) and 80.3% (for cirrhosis). A model excluding DPCs retained ALP, AST/ALT ratio, total bilirubin, Hispanic ethnicity, and gender (AUROC=0.81 and 0.78 on learning and testing data, respectively).ConclusionAn algorithm using laboratory results and DPCs can categorize a majority of PBC patients as cirrhotic or noncirrhotic with high accuracy (with a small remaining group of patients' cirrhosis status indeterminate). In the absence of biopsy data, this EHR-based model can be used to identify cirrhosis in cohorts of PBC patients for research and/or clinical follow-up.

The cure of chronic hepatitis C infection has a major impact on the morbidity and mortality of infected patients. It is now clear that sustained virologic response improves overall survival and significantly reduces the risk of liver failure, fibrosis progression, need of liver transplantation, and incidence of hepatocellular carcinoma. Moreover, hepatitis C eradication improves a broad range of extrahepatic manifestations, such as dermatologic, neoplastic, cardiovascular, and endocrine, and improves quality of life.

Background Changing US demographics and evolving chronic hepatitis B (CHB) treatments may affect longitudinal trends in CHB-related complications. We studied trends in the prevalence of cirrhosis (past or present) and incidence of all-cause mortality, stratified by patient age, sex, race, and antiviral treatment status, in a sample from US health care systems. Methods Joinpoint and Poisson regression (univariate and multivariable) were used to estimate the annual percent change in each outcome from 2006 to 2016. Results Among 5528 CHB patients, cirrhosis prevalence (including decompensated cirrhosis) rose from 6.7% in 2006 to 13.7% in 2016; overall mortality was unchanged. Overall rates of cirrhosis and mortality were higher among treated patients, but adjusted annual percent changes (aAPC) were significantly lower among treated than untreated patients (cirrhosis: aAPC +2.4% vs. +6.2%, mortality: aAPC -3.9% vs. +4.0%). Likewise, among treated patients, the aAPC for mortality declined -3.9% per year whereas among untreated patients, mortality increased +4.0% per year. Conclusions From 2006 to 2016, the prevalence of cirrhosis among CHB patients doubled. Notably, all-cause mortality increased among untreated patients but decreased among treated patients. These results suggest that antiviral treatment attenuates the progression of cirrhosis and the risk of death among patients with CHB.

Serum phosphatidylethanol (PEth) is a highly sensitive test to detect alcohol use. We evaluated whether the availability of PEth testing impacted rates of liver transplant evaluation terminations and delistings.Medical record data were collected for patients who initiated transplant evaluation due to alcohol-related liver disease in the pre-PEth (2017) or PEth (2019) eras. Inverse probability weighting (IPW) was used to balance baseline patient characteristics. Outcomes included termination of evaluation or delisting due to alcohol use; patients were censored at receipt of transplant; death was considered a competing risk. The Fine-Gray method was performed to determine whether PEth testing affected risk of evaluation termination/ delisting due to alcohol use.Three hundred and seventy-five patients with alcohol-related indications for transplant (157 in 2017; 210 in 2019) were included. The final IPW-adjusted model for the composite outcome of terminations/delisting due to alcohol use retained two significant variables (P .05): PEth era and BMI category. Patients evaluated during the PEth era were almost three times more likely to experience an alcohol-related termination/delisting than those in the pre-PEth era (sHR = 2.86; 95%CI 1.67-4.97) CONCLUSION: We found that availability of PEth testing at our institution was associated with a higher rate of exclusion of patients from eligibility for liver transplant. Use of PEth testing has significant potential to inform decisions regarding transplant candidacy for patients with alcohol-related liver disease.

We compared rates of emergency department visits and hospitalizations between patients with hepatitis C virus who achieved sustained virological response after direct-acting antiviral therapy (case patients) and matched controls. Among 3049 pairs, case patients demonstrated lower rates of liver-related emergency department visits (P = .01) than controls; all-cause and liver-related hospitalization rates and number of hospitalized days were also lower in case patients (P .001).

The nucleos(t)ide analogues (NAs) entecavir (ETV), tenofovir disoproxil fumarate (TDF) and tenofovir alafenamide (TAF) are preferred treatment options for patients with chronic hepatitis B infection (CHB). However, resistance to ETV has been reported, especially with prior exposure to other NAs, and long-term TDF treatment has been associated with decline in renal function and loss of bone mineral density in some patients. Consequently, TAF may be preferable to ETV, TDF or other NAs in specific circumstances such as in patients with risk of bone or renal complications, elderly patients or those with previous NA experience.To provide a summary of the available efficacy and safety data following switch to TAF from other NAs in patients with CHB in clinical studies and real-world settings.Literature searches were performed on PubMed and abstracts from three major international liver congresses between 2019 and 2021. Studies that included efficacy and/or safety data for patients with CHB switching from any NA to TAF were selected.Thirty-six papers and abstracts were included in this narrative review. Switching from TDF to TAF maintained or improved virological and biochemical responses with improved bone and renal safety. Switching from ETV or other NAs to TAF maintained or improved virological and biochemical responses and varying results for bone and renal safety.Switching to TAF appears to maintain or improve virological, biochemical and bone- and renal-related safety outcomes. These data support the concept of switching to TAF in some patients with CHB based on their individual circumstances.

OBJECTIVES As the prevalence of nonalcoholic steatohepatitis (NASH) in the elderly population increases, healthcare resource utilization (HCRU) and costs are also predicted to rise substantially. METHODS This retrospective, observational cohort study used the Medicare 20% sample data set to evaluate the impact of NASH severity on HCRU and costs over 8 years (2007-2015). The sample included 255,681 patients with nonalcoholic fatty liver disease (NAFLD)/NASH: 185,407 (72.5%) with NAFLD/NASH and no further progression to advanced liver disease, 3,454 (1.3%) with compensated cirrhosis (CC), 65,926 (25.8%) with decompensated cirrhosis (DCC), 473 (0.2%) with liver transplant (LT), and 421 (0.2%) with hepatocellular carcinoma (HCC). RESULTS Rates of comorbid diabetes, hypertension, hyperlipidemia, and cardiovascular disease were significantly higher in patients with CC or more severe liver disease compared with NAFLD/NASH and no progression. The annual mean number of all-cause healthcare visits increased from 32.1 for NAFLD/NASH with no progression to 37.3 for CC, 59.8 for DCC, 74.1 for LT, and 59.3 for HCC (P < 0.05). Total annual costs for inpatient, outpatient, physician, and pharmacy services rose from $19,908 in NAFLD/NASH with no progression to $129,276 for LT (P < 0.05). Generalized linear model adjusted for patient characteristics and comorbidities revealed that costs were 1.19, 3.15, 5.02, and 3.33 times significantly higher in patients diagnosed with CC, DCC, LT, or HCC, respectively, compared with NAFLD/NASH and no progression. DISCUSSION These results confirm the substantial impact of NASH, particularly more severe disease, on HCRU and costs and identify patients who may benefit from interventions to prevent progression and subsequently reduce HCRU and costs.

The role of ribavirin (RBV) in the era of direct-acting antivirals (DAA) is not clear, and DAA studies have been largely genotype- and regimen-specific. Using data from the Chronic Hepatitis Cohort Study, we evaluated the role of RBV and increased DAA treatment duration among patients with chronic hepatitis C (HCV) in routine clinical care. We performed multivariable analysis of data from 4133 patients receiving any of the following: sofosbuvir (SOF); daclatasvir + SOF; grazoprevir + elbasvir; paritaprevir/ritonavir + ombitasvir; simeprevir + SOF; and SOF + ledipasvir; SOF + velpatasvir ± voxilaprevir; and glecaprevir + pibrentasvir—all with/ without RBV. Inverse probability treatment weighting was used to adjust for treatment selection bias. Sustained virological response (SVR) was defined by undetectable HCV RNA 12 weeks after end of therapy. The overall SVR rate was 95%. Mean treatment duration was 12 ± 4.5 weeks. The final model included treatment duration and diabetes, as well as the interaction of RBV with previous treatment status (treatment naïve, interferon treatment failure [TF] or previous DAA TF), cirrhosis status, and HCV genotype (GT). Each one-month increment of treatment duration increased odds of SVR by 99% (aOR = 1.99). Diabetes, previous DAA TF, and decompensated cirrhosis significantly reduced odds of SVR. RBV significantly increased the likelihood of SVR among patients with decompensated cirrhosis (aOR = 5.05), previous DAA treatment failure (aOR = 5.43), and GT3 (aOR = 13.28). Among RBV-free regimens, patients with GT3 were less likely to achieve SVR than those with GT1 or 2 (aOR 0.07). Diabetes, decompensated cirrhosis, and prior DAA TF independently reduced the likelihood of SVR. Longer treatment duration increased likelihood of SVR. Conclusion: RBV increased likelihood of SVR among patients with GT3, previous DAA TF, or decompensated cirrhosis.

Given the goal of hepatitis C virus elimination by 2030, World Health Organization guidelines recommend treatment of chronic hepatitis C (CHC) with pan-genotypic direct-acting antivirals, such as sofosbuvir/velpatasvir (SOF/VEL), SOF/VEL/voxilaprevir (VOX) or glecaprevir/pibrentasvir (GLE/PIB). The study evaluated the cost-effectiveness of pan-genotypic regimens in initial (SOF/VEL or GLE/PIB) and re-treatment (SOF/VEL/VOX or GLE/PIB+SOF+ribavirin (RBV)) of CHC.A Markov state-transition model projected lifetime CHC health and economic outcomes from the US payer perspective. Model inputs were sourced from clinical trials or published literature and validated by hepatologists. Model outcomes included numbers of advanced liver disease events, life-years and quality-adjusted life-years (QALYs) gained, and total lifetime costs. One-way sensitivity analyses were performed on model results.SOF/VEL followed by SOF/VEL/VOX resulted in comparable cure rates to the GLE/PIB treatment pathway (99.94% vs. 99.93%, respectively). SOF-based regimens provided similar QALYs at a lower lifetime cost versus a GLE/PIB treatment pathway ($30,749 vs. $36,255), resulting in cost savings of $5,506 per patient. Results were robust in sensitivity analyses.SOF/VEL followed by SOF/VEL/VOX leads to comparable cure rates in the overall CHC population relative to the GLE/PIB treatment pathway. Based on wholesale acquisition prices, the SOF/VEL treatment pathway led to lower lifetime costs.

BACKGROUND: Six-monthly hepatocellular carcinoma (HCC) screening in cirrhotic patients has been recommended since 2011. HCC prognosis is associated with diagnosis at an early stage. We examined the prevalence and correlates of 6-monthly HCC surveillance in a cohort of HCV-infected cirrhotic patients. METHODS: Data were obtained from the medical records of patients receiving care from four hospitals between January 2011 and December 2016. Frequencies and logistic regression were conducted. RESULTS: Of 2,933 HCV-infected cirrhotic patients, most were ≥ 60 years old (68.5%), male (62.2%), White (65.8%), and had compensated cirrhosis (74.2%). The median follow-up period was 3.5 years. Among these patients, 10.9% were consistently screened 6 monthly and 21.4% were never screened. Patients with a longer history of cirrhosis (AOR = 0.86, 95% CI = 0.80–0.93) were less likely to be screened 6 monthly while decompensated cirrhotic patients (AOR = 1.39, 95% CI = 1.06–1.81) and cirrhotic patients between 18 and 44 years (AOR = 2.01, 95% CI = 1.07–3.74) were more likely to be screened 6 monthly compared to compensated cirrhotic patients and patients 60 years and older respectively. There were no significant differences by race, gender, or insurance type. CONCLUSION: The prevalence of consistent HCC surveillance remains low despite formalized recommendations. One in five patients was never surveilled. Patients with a longer history of cirrhosis were less likely to be surveilled consistently despite their greater HCC risk. Improving providers’ knowledge about current HCC surveillance guidelines, educating patients about the benefits of consistent HCC surveillance, and systemic interventions like clinical reminders and standing HCC surveillance protocols can improve guideline-concordant surveillance in clinical practice.

Chronic hepatitis B (CHB) comorbidity data are limited. Using insurance claims databases, our aims were to determine the prevalence and incidence of nonliver comorbidities in CHB patients over time and the predictors of select comorbidities in CHB patients. Patients were adults with continuous coverage (commercial/Medicare or Medicaid) 6 months prior to and after the first CHB diagnosis and matched non‐CHB patients. Deyo‐Charlson Comorbidity Index (DCCI) and comorbidities were analyzed (cardiovascular disease [CVD], carcinoma, diabetes mellitus [DM], obesity, hypertension [HTN], hyperlipidemia, alcohol use, renal impairment, chronic kidney disease [CKD], and osteoporosis/fracture [OF]). The study population included 44,026 CHB cases and 121,568 matched controls. CHB patient mean age increased from 48.1 ± 11.9 years in 2006 to 51.8 ± 12.4 years in 2015 for commercial/Medicare and from 44.1 ± 11.1 years to 50.2 ± 10.2 years for Medicaid (P < 0.001 for both). The Medicaid CHB cohort was the sickest (DCCI, 2.6, P < 0.001). The commercial/Medicare 2006 CKD prevalence rate was 36.1/1,000 in CHB patients and 10.2/1,000 in controls, increasing to 97.6 and 38.8 in 2015, respectively. The 2006 CKD incidence (per 1,000 person‐years) was 10.3 and 4.8 and 15.2 and 11.3 by 2015, respectively (P < 0.05 for all). The strongest predictors for CKD were DM (hazard ratio [HR], 2.48), HTN (HR, 3.29), and CVD (HR, 2.61) (all P < 0.0001). Similar prevalence and incidence changes were observed for OF. The strongest predictors for OF were female gender (HR, 2.22), alcohol use (HR, 2.02), and viral coinfection (HR, 1.37) (all P < 0.0001). Conclusion: Insured CHB patients were older, had more comorbidities, and experienced higher incidence and prevalence of CKD and OF than controls.

[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 and aims There is an unmet need for alternative treatments for patients with primary biliary cholangitis (PBC) who do not respond to treatment with ursodeoxycholic acid (UDCA). A proof-of-concept study of baricitinib, an orally administered Janus kinase 1 and 2 inhibitor, was initiated to evaluate its use in PBC patients. Approach and results Patients with PBC showing inadequate response or intolerance to UDCA were eligible. This was a randomized, double-blinded placebo-controlled trial. Enrollees were assigned 1:1 to baricitinib (2 mg/day) or placebo. Endpoints included change in alkaline phosphatase (ALP), itch Numeric Rating Score (NRS), and fatigue NRS at 12 weeks post-baseline; exploratory markers included high sensitivity C-reactive protein (hs-CRP) and Enhanced Liver Fibrosis (ELF) score. Due to low enrollment, the study was terminated early. Two patients were enrolled and completed the trial; 1 was randomized to receive baricitinib and 1 to placebo. Over the treatment period, the baricitinib-treated patient demonstrated a 30% decrease in ALP and a 7-point improvement in the itch NRS, but a 2-point increase in the Fatigue NRS. Markers of inflammation and liver fibrosis (hs-CRP and ELF score) also improved over the study period. In contrast, the placebo-treated patient showed no improvement in primary or secondary endpoints. A single non-serious treatment-emergent adverse event of moderate sinusitis was reported by the baricitinib-treated patient at day 47. Conclusions In a 12-week trial, a patient with PBC showing inadequate response to treatment with UDCA demonstrated a dramatic response to treatment with baricitinib., Highlights • Baricitinib is an orally administered Janus kinase 1 and 2 inhibitor FDA-approved for rheumatoid arthritis. • A primary biliary cholangitis patient with inadequate response to UDCA demonstrated a dramatic response to treatment with baricitinib. • Response included rapid reduction in alkaline phosphatase and in self-reported measures of pruritus and depression during the 12-week trial.

Background TAF demonstrated noninferior efficacy to TDF with a superior bone and renal safety profile, in viremic chronic HBV (CHB) patients through week 96, and in virally suppressed patients switched from TDF to TAF at 48 weeks. The duration of prior TDF therapy may influence the degree and rate of recovery of bone and renal function following switch to TAF. Here, we evaluate the impact of prior TDF treatment duration on the safety profile of TAF in virally suppressed patients. Methods In a double-blind, randomized, multicenter, active-controlled, Phase 3 study, 488 CHB patients who were virologically suppressed on TDF for 1 year, and on TDF monotherapy for 6 months were randomized 1:1 to switch to TAF or continue TDF for 48 weeks. In patients originally randomized to receive TAF, renal, bone, and lipid parameters were categorically evaluated by the duration of prior TDF treatment: Results Of the 243 patients switched to TAF from TDF, 105 (43%) and 138 (57%) had received TDF for 50 years, 74% male, 80% Asian, median eGFRCG91 mL/min, 4% and 12% had osteoporosis at hip and spine, respectively. Similar changes in renal, bone, and lipid parameters following 48 weeks of TAF treatment were observed by TDF treatment duration. A comparable increase in median eGFRCG, decreases in tubular biomarkers (beta-2 microglobulin/creatinine ratio, retinol binding protein/creatinine ratio), increases in mean percent change in hip and spine BMD, and decreases in bone turnover markers (C-type collagen sequence, procollagen type 1 N-terminal propeptide) were observed among patients previously treated with Conclusions In virally suppressed patients on TDF a median of 4 years who switched to TAF treatment, improvements in bone and renal parameters and changes in fasting lipids were not impacted by prior duration of TDF use.

Background TDF and ETV are first-line treatments for CHB virus infection. A recent analysis of nationwide insurance data from Korea suggested that the risk of HCC may vary by type of CHB treatment; however, this finding was based on a limited follow-up period following TDF approval in Korea in 2012 and has not been replicated in large datasets outside of Asia. The objective of this analysis was to explore the long-term risk of HCC with TDF vs. ETV in treatment naive (TN) CHB patients in a US administrative claims dataset. Methods Among 158,272 patients with evidence of CHB and administrative medical claims between January 2006 and September 2018, we identified TN patients exposed to TDF (N=6,145) or ETV (N=4,046) with at least 1 year of continuous enrollment prior to cohort entry. Exclusion criteria included coinfection with HCV, HDV, or HIV; prior exposure to peginterferon or nucleos(t)ide analogues; HCC or liver transplant prior or up to 6 months after initiating treatment. Absolute rates and corresponding 95% CIs were determined for each treatment group, Cox proportional hazards methods were used to estimate the risk of incident HCC associated with TDF vs ETV. To account for the effects of potential differences in demographics and baseline health status, we incorporated multivariable adjustment and weighting based on treatment propensity scores. Results Median follow-up duration was comparable in TDF- vs ETV-treated patients among TDF-treated CHB patients, the absolute rate of HCC was approximately half that of patients treated with ETV (0.32 per 100 PY (CI: 0.23 – 0.43) vs 0.61 per 100 PY (CI: 0.45 – 0.80)). After adjustment for age group, sex, baseline health conditions and propensity score weighting, TDF remained associated with a significantly decreased risk of HCC compared to treatment with ETV (HR: 0.56, CI: 0.37 – 0.86). Conclusions In this analysis of commercially insured, TN CHB patients in the US, the absolute rate of HCC was lower in those treated with TDF than with ETV. After adjustment, treatment with TDF remained associated with a significantly decreased long term risk of HCC, consistent with recent findings from Asia.

Using electronic health records, we found that hepatitis C virus (HCV) reporting on death certificates of 2901 HCV-infected decedents from 4 US healthcare organizations during 2011–2017 was documented in only 50% of decedents with hepatocellular carcinoma and less than half with decompensated cirrhosis. National figures likely underestimate the US HCV mortality burden.

Introduction Despite recognized differences in the rates of cardiovascular and renal disease between men and women in the general population, studies of the downstream effects of antiviral treatment for hepatitis C (HCV) have not investigated differences in outcomes based on sex. We analyzed sex differences in risk of acute coronary syndrome (ACS), end-stage renal disease (ESRD), and ischemic stroke by treatment and response in a large US-based multisite cohort of HCV patients. Methods Observation started at the HCV diagnosis date (untreated) or last antiviral treatment start (treated). Treatment selection bias was addressed using an inverse probability-weighting approach. We estimated the effect of treatment on the cumulative incidence of outcomes using the Fine-Gray method (subdistribution hazard ratios [sHR] and 95% confidence intervals [95% CI]). Death was a competing risk. Results Roughly 40% of 15,295 HCV patients were women. After controlling for other risk factors, sustained virological response (SVR) (interferon-based [IFN] or direct-acting antiviral [DAA]) significantly reduced risk of all outcomes, particularly among female patients. Female patients who achieved SVR after IFN-based treatment had significantly lower risk of ACS compared with male patients with SVR from either treatment type (sHR 0.45 [95% CI 0.35-0.59] vs 0.81 [95% CI 0.69-0.96, for DAA SVR] and sHR 0.72 [95% 0.62, 0.85, for IFN SVR]). Successful treatment seemed to be most protective against ESRD; female patients who achieved SVR were at 66%-68% lower risk than untreated patients (sHR 0.32 [95% CI 0.17-0.60 for DAA SVR] and 0.34 [95% CI 0.20-0.58 for IFN SVR]), whereas men were at 38%-42% lower risk (sHR 0.62 [95% CI 0.46-0.85 for DAA SVR] and 0.58 [95% CI 0.43-0.76 for IFN SVR]). IFN treatment failure significantly increased risk of all outcomes by 50%-100% among female patients. Compared with no treatment, female patients who experienced IFN treatment failure were at 63% increased risk of ACS (sHR 1.63 [95% CI 1.35-1.96]), almost twice the risk of ESRD (sHR 1.95 [95% CI 1.43-2.66]) and 51% increased risk of stroke (sHR 1.49 [95%CI 1.11-2.00]). Discussion SVR reduced the risk of extrahepatic complications, particularly in females. The significantly increased risk associated with IFN TF in women-a subset who represented roughly 10% of that group-underscores the importance of prioritizing these patients for DAA treatment irrespective of the fibrosis stage.

Summary Exposure to hepatitis viruses is a recognized occupational risk for health care personnel (HCP). This report establishes new CDC guidance that includes recommendations for a testing algorithm and clinical management for HCP with potential occupational exposure to hepatitis C virus (HCV). Baseline testing of the source patient and HCP should be performed as soon as possible (preferably within 48 hours) after the exposure. A source patient refers to any person receiving health care services whose blood or other potentially infectious material is the source of the HCP’s exposure. Two options are recommended for testing the source patient. The first option is to test the source patient with a nucleic acid test (NAT) for HCV RNA. This option is preferred, particularly if the source patient is known or suspected to have recent behaviors that increase risk for HCV acquisition (e.g., injection drug use within the previous 4 months) or if risk cannot be reliably assessed. The second option is to test the source patient for antibodies to hepatitis C virus (anti-HCV), then if positive, test for HCV RNA. For HCP, baseline testing for anti-HCV with reflex to a NAT for HCV RNA if positive should be conducted as soon as possible (preferably within 48 hours) after the exposure and may be simultaneous with source-patient testing. If follow-up testing is recommended based on the source patient’s status (e.g., HCV RNA positive or anti-HCV positive with unavailable HCV RNA or if the HCV infection status is unknown), HCP should be tested with a NAT for HCV RNA at 3–6 weeks postexposure. If HCV RNA is negative at 3–6 weeks postexposure, a final test for anti-HCV at 4–6 months postexposure is recommended. A source patient or HCP found to be positive for HCV RNA should be referred to care. Postexposure prophylaxis of hepatitis C is not recommended for HCP who have occupational exposure to blood and other body fluids. This guidance was developed based on expert opinion (CDC. Updated U.S. Public Health Service guidelines for the management of occupational exposures to HBV, HCV, and HIV and recommendations for postexposure prophylaxis. MMWR Recommend Rep 2001;50[No. RR-11]; Supplementary Figure, https://stacks.cdc.gov/view/cdc/90288) and reflects updated guidance from professional organizations that recommend treatment for acute HCV infection. Health care providers can use this guidance to update their procedures for postexposure testing and clinical management of HCP potentially exposed to hepatitis C virus.

Normal ranges of serum alanine aminotransferase (ALT) may vary by race. However, results from research studies are contradictory, and many of these studies have included only small numbers of African Americans. We investigated ALT values in patients without evidence of liver disease to determine whether normal ranges differ across race groups. We also evaluated whether a race- and sex-dependent upper limit of normal (ULN) would improve the ability of ALT to predict liver disease compared to the sex-dependent ULN currently in use. We identified ICD9 codes for liver conditions and diabetes in medical records from a sample of 6719 patients. Analysis of variance (ANOVA) was used to assess differences in ALT log-transformed distributions by race. Logistic regression was used to evaluate whether the addition of race to the current sex-dependent ULN improves the ability of ALT to predict liver disease (assessed by area under the receiver operating characteristic curve (AUROC)). Among 1200 patients with BMI 18.5

The cure of chronic hepatitis C infection has a major impact on the morbidity and mortality of infected patients. It is now clear that sustained virologic response improves overall survival and significantly reduces the risk of liver failure, fibrosis progression, need of liver transplantation, and incidence of hepatocellular carcinoma. Moreover, hepatitis C eradication improves a broad range of extrahepatic manifestations, such as dermatologic, neoplastic, cardiovascular, and endocrine, and improves quality of life.

Supplemental Digital Content is available in the text., Goals: This study evaluates the real-world comorbidity burden, health care resource utilization (HRU), and costs among nonalcoholic fatty liver disease/nonalcoholic steatohepatitis (NAFLD/NASH) patients with advanced liver diseases [compensated cirrhosis (CC), decompensated cirrhosis (DCC), liver transplantation (LT), hepatocellular carcinoma (HCC)]. Background: NAFLD/NASH is a leading cause of liver diseases. Materials and Methods: Adult NAFLD/NASH patients were identified retrospectively from MarketScan Commercial claims (2006-2016). Following initial NAFLD/NASH diagnosis, advanced liver diseases were identified using the first diagnosis as their index date. Mean annual all-cause HRU and costs (2016 USD) were reported. Adjusted costs were estimated through generalized linear models. Cumulative costs were illustrated for patient subsets with variable follow-up for each stage. Results: Within the database, 485,774 NAFLD/NASH patients met eligibility criteria. Of these, 93.4% (453,564) were NAFLD/NASH patients without advanced liver diseases, 1.6% (7665) with CC, 3.3% (15,833) with DCC, 0.1% (696) with LT, and 0.1% (428) with HCC. Comorbidity burden was high and increased as patients progressed through liver disease severity stages. Compared with NAFLD/NASH without advanced liver diseases (adjusted costs: $23,860), the annual cost of CC, DCC, LT, and HCC were 1.22, 5.64, 8.27, and 4.09 times higher [adjusted costs: $29,078, $134,448, $197,392, and $97,563 (P

Goals To determine the proportion and characteristics of adults with hepatitis C at health care organizations in 4 US states who initiated direct-acting antivirals (DAAs). Background There are almost no data to assess the penetrance of treatment of the hepatitis C population in general US health care settings. Study We conducted a prospective observational study using electronic clinical, pharmacy, and mortality data to determine the fraction of patients who initiated DAAs between January 2014 and December 2017, by start date and regimen. We used stepwise multivariate logistic regression analysis to identify sociodemographic and clinical characteristics associated with receipt of DAAs. Results Of 8823 patients, 2887 (32.7%) received DAAs. Quarterly (Q) uptake ranged from 1.1% in Q3 2014 to a high of 5.6% in Q2 2015. Characteristics associated with receipt of DAAs included age 51 to 70 years, higher income, pre-2014 treatment failure, and higher noninvasive fibrosis score (FIB4); however, over one half of patients with FIB4 scores >3.25, consistent with severe liver disease, were not treated. A lower likelihood of initiation was associated with Medicaid coverage. Of 5936 patients who did not initiate treatment, 911 (15.3%) had died and 2774 (46.7%) had not had a clinical encounter in ≥12 months by the end of the study. Fewer than 1% of DAA prescriptions originated from nonspecialty providers. Conclusions During 4 calendar years of follow-up, one third of patients initiated DAAs. Large fractions of untreated patients had advanced liver disease, died, or were lost to follow-up. Even among patients in integrated health care systems, receipt of DAAs was limited.
