Backgrounds and Aims: A potent and safe antiviral agent may impact chronic hepatitis C (HCV)‐related end‐stage liver disease (ESLD). We assess aetiology‐based hospitalizations for ESLD in the United States, 2016–2019. Methods: We utilized the National Inpatient Sample (NIS) from 2016 to 2019. We defined ESLD as either decompensated cirrhosis or hepatocellular carcinoma, criteria obtained from the International Classification of Diseases, Tenth Revision. Results: National hospitalization rates for non‐alcoholic fatty liver disease (NAFLD) increased significantly from 67.1/100 000 persons in 2016 to 93.6 in 2019 with an average annual percentage change (AAPC) of 12.1%, while chronic hepatitis C (HCV) decreased significantly from 71.2/100 000 persons in 2016 to 58.5 in 2019 (−6.5% AAPC). Hospitalizations for ESLD in alcohol‐related liver disease (ALD) increased as well. Conclusions: Hospitalization rates for NAFLD‐ and ALD‐related ESLD increased steadily, while those for HCV‐related ESLD decreased during the direct‐acting antivirals era. [ABSTRACT FROM AUTHOR]

Background: Data on the current estimates of the disease burden of Clostridioides difficile (C. difficile) infection in the setting of end-stage liver disease (ESLD) are emerging. Aims: We examined the recent trends and predictors of hospitalizations and in-hospital mortality from C. difficile infection among hospitalizations with ESLD in the USA. Methods: We performed a retrospective analysis using the National Inpatient Sample, 2005–2014. We defined ESLD and C. difficile infection using the International Classification of Diseases, Ninth Revision, Clinical Modification. Multivariable logistic regression was used to determine the risk factors that impacted hospitalization and mortality. Results: The prevalence of coding for C. difficile infection in decompensated cirrhosis increased from 1.3% in 2005 to 2.7% in 2014, with an annual rate of 7.8%. In hospitalizations with hepatocellular carcinoma, C. difficile infection increased steadily from 1.0 to 1.7% with an annual incremental rate of 6.4%. Among hospitalizations with ESLD, each passing 2-year period, increasing age, female, higher Charlson index, accompanying infection, hepatorenal syndrome, and ascites were associated with C. difficile infection. Although C. difficile infection was an independent predictor of in-hospital mortality during hospitalization with decompensated cirrhosis (odds ratio 1.53, 95% confidence interval 1.44–1.63), the proportion of in-hospital mortality during hospitalization with C. difficile infection and decompensated cirrhosis decreased from 15.4% in 2005 to 11.1% in 2014, with an annual rate of − 3.1% (95% CI − 5.7% to − 0.3%). Conclusions: While the prevalence of C. difficile infection in hospitalized patients with ESLD increased approximately twofold, the in-hospital mortality decreased significantly during the past decade.

Background & Aims Cirrhosis from hepatitis C virus (HCV) infection is a major cause of end-stage liver disease and hepatocellular carcinoma worldwide. We determine the prevalence of cirrhosis among HCV-infected American adults including those unaware of their infection. Methods Using the National Health and Nutrition Examination Survey (NHANES) data, we identified participants aged ⩾20 years with detectable serum HCV RNA. The prevalence of advanced fibrosis and cirrhosis was determined for eras 1 (1988–94), 2 (1999–2006) and 3 (2007–2012) by using FIB-4 >3.25 and APRI >2.0, respectively. Results Out of 52,644 NHANES examinees, 49,429 were tested for HCV, of whom 725 met the inclusion criteria (positive HCV RNA with available data for FIB-4 and APRI). Based on APRI, 6.6% (95% confidence interval [CI]: 2.2–11.0) of HCV-infected adults in era 1, 7.6% (95% CI: 3.4–11.8) in era 2 and 17.0% (95% CI: 8.0–26.0) in era 3 had cirrhosis. In the multivariable regression analysis, this era effect was attributable to increasing age (odds ratio [OR]:1.04, 95% CI: 1.02–1.07), diabetes (OR: 2.33, 95% CI: 1.01–5.40) and obesity (OR: 2.96, 95% CI: 1.15–7.57). Cirrhosis was as common among respondents who were unaware of their infection as those who were aware (both 11%). Results were identical when FIB-4 was used. Conclusions Among HCV-infected American adults, the proportion with cirrhosis has increased rapidly. Cirrhosis prevalence remains high in individuals unaware of their HCV infection. These data highlight the urgency for HCV screening regardless of symptoms, systematic assessment for liver fibrosis in those with HCV infection and institution of antivirals to prevent advanced liver disease. Lay summary Chronic hepatitis C virus (HCV) infection is a major cause of cirrhosis, creating a large public health burden. Based on the U.S. National Health and Nutrition Examination Survey sample, we found the proportion of patients with cirrhosis among Americans with HCV infection increased from 6.6% to 17.0% over the past two decades. Patients who were unaware of their infection were just as likely to have cirrhosis as those who knew about their infection, which highlights the need for screening and treatment for HCV at the population level.
