ABSTRACT: Early recognition and prompt intervention are the most crucial steps in the management of gallstone-induced biliary disease. Many conditions can mimic the presentation of gallstone-induced complications. Therefore, participation of a clinically astute physician is essential in evaluating symptoms and interpreting diagnostic data in patients with symptomatic gallstones. [ABSTRACT FROM AUTHOR]

INTRODUCTION: The purpose of this study was to evaluate hepatitis delta virus (HDV) testing patterns among US adults with chronic hepatitis B (CHB). METHODS: HDV testing was evaluated among CHB patients using Quest Diagnostics (2016–2020) and Veterans Affairs (2010–2020) data. RESULTS: Among 157,333 CHB patients (Quest), 6.7% received HDV testing, among which 2.2% were positive. HDV testing was higher in male patients, younger individuals, and patients with advanced liver disease. Among 12,002 CHB patients (Veterans Affairs), 19.7% received HDV testing, among which 3.1% were positive. HDV testing was higher in younger individuals and Asians. DISCUSSION: Low HDV testing was observed among 2 large US cohorts of adults with CHB. [ABSTRACT FROM AUTHOR]

INTRODUCTION: Nonalcoholic fatty liver disease (NAFLD) and infection with hepatitis B virus (HBV) or hepatitis C virus (HCV) are major causes of liver disease in adults. However, data for children and adolescents are limited. Our study aimed to characterize the prevalence, trend, and risk factors of infection of HBV and HCV and possible NAFLD for this population. METHODS: We analyzed 6,647 children and adolescents (aged 6–21 years) from the 1999–2016 National Health and Nutrition Examination Survey. RESULTS: Among individuals aged 6–21 years, HBV prevalence decreased after 2011, from 0.72% in 1999–2004 and 0.85% in 2005–2010 to 0.27% in 2011–2016 (P < 0.001), whereas HCV prevalence increased to 0.26% in 2011–2016 after an initial decline from 0.15% in 1999–2004 to 0.02% in 2005–2010 (P = 0.01). Possible NAFLD prevalence also increased by approximately 40% in individuals aged 12–21 years, from 8.54% in 1999–2004 to 10.1% in 2005–2010 and then 11.8% in 2011–2016 (P = 0.033), with most possible NAFLD individuals being male, being obese, or having higher glucose, fasting insulin, hemoglobin A1c, homeostatic model assessment of insulin resistance, liver enzymes, lipids, and uric acid (all P < 0.01). On multivariate logistic regression, hypertension (odds ratio 4.79, 95% confidence interval 1.44–15.9) and dyslipidemia (odds ratio 11.6, 95% confidence interval 5.65–23.9) increased risk for possible NAFLD but not income:poverty ratio, hours spent on computer use, or added sugars. DISCUSSION: Although HBV prevalence has decreased in recent years among US children and adolescents, HCV and possible NAFLD have increased. Public health efforts must seek further understanding of the driving factors of this increase so that age-appropriate interventions can be developed and implemented. [ABSTRACT FROM AUTHOR]

INTRODUCTION: Previous studies, mostly small and single center, have shown gaps in the evaluation and monitoring of patients with chronic hepatitis B (CHB) virus infection. We aimed to examine the rates and predictors of adherence to guidelines for CHB care in a large nationwide cohort. METHODS: Weidentified adult patients withCHBinfection from the Truven MarketScan databases of commercially insured and Medicare patients with private insurance supplement (2007-2014) using International Classification of Diseases, Ninth Revision, Clinical Modification codes. The initial evaluation cohort had at least 6 months follow-up, whereas at least 12 months was required for the long-term monitoring cohort. RESULTS: We analyzed 55,317 eligible patients with CHB infection: mean age 46 6 12 years, 58% men, and 14.8% with cirrhosis. Over a mean follow-up of 3.262.3 years, 55.8% had specialist (gastroenterology or infectious diseases) visits. For initial evaluation, 59% of patients received both alanine aminotransferase (ALT) and hepatitis B virus (HBV) DNA tests, whereas only 33% had ALT, HBV DNA, and hepatitis B e antigen tests, with higher frequencies among patients with specialist visits. For longterm monitoring, only 25% had both ALT and HBV DNA tests performed annually. Among patients at higher risk of developing hepatocellular carcinoma (patients with cirrhosis, male patients without cirrhosis older than 40 years, and female patients without cirrhosis older than 50), less than 40% underwent annual hepatocellular carcinoma surveillance, with25%never receiving surveillance during the study period. Predictors of optimal initial evaluation and long-term monitoring were compensated cirrhosis (odds ratio: 1.60 and 1.47, respectively) and specialist visits (odds ratio: 1.86 and 1.31, respectively) (both P < 0.001). DISCUSSION: In this large cohort of patients with CHB infection with private insurance or Medicare with private insurance supplement, we observed poor adherence to the recommended initial evaluation and longterm monitoring. Among the predictors of adherence were specialist visits. Further efforts are needed to identify barriers and improve access to care. [ABSTRACT FROM AUTHOR]

INTRODUCTION: Entecavir (ETV) and tenofovir alafenamide (TAF) are both first-line hepatitis B virus (HBV) therapies, but ETV-to-TAF switch outcome data are limited. We aimed to assess outcomes up to 96 weeks after ETV-to-TAF switch. METHODS: ETV-treated (≥12 months) chronic hepatitisBpatients switched to TAF in routine practice at 15 centers (United States, Korea, Japan, and Taiwan) were included. Primary outcome was complete viral suppression (CVS) rate (HBV DNA <20 IU/mL). RESULTS: We analyzed 425 eligible patients (mean age 60.7613.2 years, 60% men, 90.8%Asian, 20.7% with diabetes, 27% with hypertension, 14.8% with cirrhosis, 8.3% with hepatocellular carcinoma, and mean ETV duration before switch 6.16 ± 3.17 years). The mean baseline estimated glomerular filtration rate (eGFR) was 89619 (chronic kidney disease [CKD] stages: 55.6% stage 1, 35.7% stage 2, and 8.8% stages 3-5). CVS rate increased from 91.90% at switch (from 90.46% 24 weeks before switch) to 95.57% and 97.21%at 48 and 96 weeks after (P = 0.03 and 0.02, respectively). Over the 96 weeks after switch, mean HBV DNA (P < 0.001) but not alanine aminotransferase or CKD stage decreased. Between switch and 96-week follow-up, 11% (26/235) of CKD stage 1 patients migrated to stage 2 and 8% (12/151) of stage 2 patients to stages 3-5, whereas 18% (27/151) from stage 2 to 1, and 19% (7/37) from stages 3-5 to 2. On multivariable generalized estimated equation analysis adjusted for age, sex, hypertension, diabetes, and cirrhosis, baseline eGFR, age (P < 0.001), and CKD stages 2 and 3-5 (vs 1) (both P < 0.001) were associated with lower follow-up eGFR. DISCUSSION: After an average of ± years on ETV, CVS increased from 91.9% at TAF switch to 97.2% at 96 weeks later. [ABSTRACT FROM AUTHOR]

BACKGROUND: African-Americans (AA) have a higher incidence of hepatocellular carcinoma (HCC) and lower survival. We characterized survival rates and clinical features associated with survival in AA vs. Caucasians with HCC over the past two decades. METHODS: HCC patients from three US medical centers were matched by year of diagnosis (1991–2016): AA (n = 578)/Caucasian (n = 578) and placed in one of two groups—HCC diagnosed prior to 2010 or 2010 and after. Data were obtained from chart review and the National Death Index. Multivariate and survival analysis controlling for key predictors were conducted. RESULTS: Prior to 2010, there was no difference in survival between Caucasians and AA (p = 0.61). After 2010, AA patients had poorer survival compared to Caucasians (35% vs. 44%, respectively, p = 0.044). Over time, survival improved for Caucasians (32% before 2010 vs. 44% after 2010, p = 0.003), but not AA (36% vs. 35%, p = 0.50). AA on presentation (in the after 2010 cohort) were more likely to have BCLC (Barcelona Clinic Liver Cancer) stage C (24% vs. 15%, p = 0.010) and less likely to receive treatment (85% vs. 93%, p = 0.002) compared to matched Caucasians. BCLC beyond stage A (aHR: 1.75, 95% CI: 1.26–2.43, p = 0.001) and child's class C (aHR 2.05, 95% CI: 1.23–3.41, p = 0.006) were the strongest predictors of mortality, while race was not. CONCLUSIONS: African-Americans presented with more advanced HCC and had poorer survival compared to Caucasians after 2010. Tumor stage was an independent predictor of mortality, but ethnicity was not. Further efforts are needed to improve early HCC diagnosis for AA. [ABSTRACT FROM AUTHOR]
