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. [ABSTRACT FROM AUTHOR]

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. [ABSTRACT FROM AUTHOR]

Background According to death certificates, approximately 1800 persons die from hepatitis B annually in the United States; however, this figure may underestimate true mortality from chronic hepatitis B (CHB). Methods We analyzed data from CHB patients seen in the Chronic Hepatitis Cohort Study (CHeCS) between 1 January 2006 and 31 December 2013. We compared overall and cause-specific death rates and mean ages at death between CHeCS CHB decedents and U.S. decedents from the Multiple Cause of Death (MCOD) file. Results Of 4389 CHB patients followed for a mean of 5.38 years, 492 (11%) CHB patients died after a mean follow-up of 3.00 years. Compared to survivors, decedents were older, more likely to be White (40.6%), African-American (27.1%), or male (74.2%); and more likely to have had cirrhosis (59.8%), diabetes (27.2%), alcohol abuse (17.7%), hepatocellular carcinoma (17.5%), or a liver transplant (5.7%); whereas survivors were more likely to be Asian (48.8%; all P <.001). CHB patients died at an average age of 59.8 years—14 years younger than the general U.S. population—and at higher rates for all causes (relative risk [RR] = 1.85, 95% confidence interval [CI], 1.851–1.857) and liver-related causes (RR = 15.91, 95% CI, 15.81–16.01). Only 19% of CHB decedents and 40% of those dying of liver disease had hepatitis B reported on their death certificates. Conclusions Compared to the general population, CHB patients die at younger ages and higher rates from all causes and liver-related causes. Death certificates underrepresent the true mortality from CHB. [ABSTRACT FROM AUTHOR]

Background. A key question in care of patients with chronic hepatitis C virus (HCV) infection is beginning treatment immediately vs delaying treatment. Risks of mortality and disease progression in "real world" settings are important to assess the implications of delaying HCV treatment. Methods. This was a cohort study of HCV patients identified from 4 integrated health systems in the United States who had liver biopsies during 2001-2012. The probabilities of death and progression to hepatocellular carcinoma, hepatic decompensation (hepatic encephalopathy, esophageal varices, ascites, or portal hypertension) or liver transplant were estimated over 1, 2, or 5 years by fibrosis stage (Metavir F0-F4) determined by biopsy at beginning of observation. Results. Among 2799 HCV-monoinfected patients who had a qualifying liver biopsy, the mean age at the time of biopsy was 50.7 years. The majority were male (58.9%) and non-Hispanic white (66.9%). Over a mean observation of 5.0 years, 261 (9.3%) patients died and 34 (1.2%) received liver transplants. At 5 years after biopsy, the estimated risk of progression to hepatic decompensation or hepatocellular carcinoma was 37.2% in stage F4, 19.6% in F3, 4.7% in F2, and 2.3% in F0-F1 patients. Baseline biopsy stage F3 or F4 and platelet count below normal were the strongest predictors of progression to hepatic decompensation or hepatocellular carcinoma. Conclusions. The risks of death and progression to liver failure varied greatly by fibrosis stage. Clinicians and policy makers could use these progression risk data in prioritization and in determining the timing of treatment for patients in early stages of liver disease. [ABSTRACT FROM AUTHOR]

Background. The phase 2 C-SALVAGE study (Hepatitis C-Salvage Study for Patients who Failed DAA/PR Therapy) demonstrated a 96.2% sustained virologic response at 12 weeks (SVR12) rate using the NS3/4A protease inhibitor grazoprevir and the NS5A inhibitor elbasvir together with ribavirin in treatment-experienced patients with chronic hepatitis C virus (HCV) genotype 1 infection. Methods. C-SALVAGE was a prospective open-label trial of grazoprevir 100 mg once daily and elbasvir 50 mg once daily coadministered with weight-based ribavirin twice daily for 12 weeks in genotype 1-infected cirrhotic and noncirrhotic patients who had failed treatment with ≤4 weeks of pegylated interferon and ribavirin plus either boceprevir, telaprevir, or simeprevir. Although the primary efficacy outcome was SVR12, patients were also evaluated 24 weeks after cessation of study therapy. Population sequencing was performed at baseline and periodically in virologic failures throughout the 24-week posttherapy follow-up period. Results. SVR24 rates were 76 of 79 (96.2%) overall, with all 3 relapses occurring by posttherapy week 8. Every NS3 and NS5Avariant detected at baseline reappeared at the time of relapse and persisted throughout the available follow-up period. NS3_A156T emerged in virus from each patient at relapse, but rapidly disappeared over the ensuing 2 weeks in 2 patients. NS5A_Y93H emerged in virus from 2 patients at relapse and persisted for the entire follow-up period. Conclusions. Grazoprevir and elbasvir with ribavirin for 12 weeks maintained HCV suppression for at least 24 weeks posttherapy without late relapses. Baseline resistance-associated variants (RAVs) stably reappeared at relapse in all 3 patients with virologic failure. NS5A_RAVs emerging at relapse persisted for the full 24-week follow-up period. If confirmed, this finding could complicate retreatment of the small number of patients failing regimens containing an NS5A inhibitor. [ABSTRACT FROM AUTHOR]

- Abstract
Background. Hepatitis A and B vaccines are effective in preventing superinfection and sequelae in patients with chronic hepatitis B or C. We describe immunity and vaccination against hepatitis A and B in chronic hepatitis patients from the US Chronic Hepatitis Cohort Study. Methods. We identified chronic hepatitis B and C patients with healthcare utilization during 2006–2008 and 12 months of enrollment. We used electronic laboratory records to determine immunity and medical and billing records for vaccination history. Immunity against hepatitis A was defined by positive hepatitis A antibody or documented vaccination. Immunity against hepatitis B was defined as hepatitis B surface antibody level ≥10 mIU/mL or core antibody positive, or by documented vaccination. Results. Among 1635 chronic hepatitis B patients, 978 (59.8%) were immune or vaccinated against hepatitis A, 122 (7.5%) had negative hepatitis A antibody tests, and 535 (32.7%) had no testing or vaccination record. Among 5328 chronic hepatitis C patients, 2998 (56.3%) were immune or vaccinated against hepatitis A, 659 (12.4%) had negative hepatitis A antibody tests, and 1671 (31.4%) had no testing or vaccination record. Additionally, 3150 (59.1%) chronic hepatitis C patients were immune or vaccinated against hepatitis B, 1003 (18.8%) had a negative test result, and 1175 (22.1%) were neither tested for nor vaccinated against hepatitis B. Conclusions. Approximately 40% of chronic hepatitis B and C patients are susceptible to or have no documented immunity or vaccination against hepatitis A or hepatitis B. Clinicians should consider antibody testing and vaccination for this vulnerable population. [ABSTRACT FROM AUTHOR]

Among persons in care during 2003–2010, we found that approximately 60% who tested positive for hepatitis C virus (HCV) antibody had a follow-up HCV RNA test to determine HCV infection status.Background. A test for hepatitis C virus (HCV) RNA is essential to identify persons with active, or current, HCV infection. We assessed trends in HCV RNA testing following a positive HCV antibody result among persons in 4 large healthcare organizations.Methods. Data collected from adults with ≥2 clinical encounters during 2003–2010 were analyzed to determine the frequency of, interval between, and factors associated with having an RNA test after a first positive HCV antibody test.Results. From 2003–2010, 5860 persons had a positive antibody test, of whom 3570 (60.9%) had a follow-up RNA test. During this period, the annual frequency of persons with an eventual RNA test did not change significantly; however, the fraction of persons who had the follow-up RNA test within 6 months improved significantly, from 45% in 2003 to 57% in 2010 (P < .001, for trend). Persons born during 1945–1965, men, and those with annual income <$30 000 (by census geocode) were less likely to have had a follow-up RNA test done within 6 months of a positive antibody test.Conclusions. Less than two-thirds of persons with a positive HCV antibody test had a follow-up RNA test. Rapid ascertainment of HCV infection status with reflex testing to RNA is critical to identify persons eligible for treatment. [ABSTRACT FROM AUTHOR]

Authors review 2 (FIB-4 and APRI) systems relying on more easily obtainable serum and cell biomarkers for liver biopsies to stage liver disease. This would be an important step in opening treatment and care of uncomplicated hepatitis C virus–infected patients.Background. Liver biopsy remains critical for staging liver disease in hepatitis C virus (HCV)–infected persons, but is a bottleneck to evaluation, follow-up, and treatment of HCV. Our analysis sought to validate APRI (aspartate aminotransferase [AST]–to-platelet ratio index) and FIB-4, an index from serum fibrosis markers (alanine aminotransferase [ALT], AST, and platelets plus patient age) to stage liver disease.Methods. Biopsy results from HCV patients in the Chronic Hepatitis Cohort Study were mapped to an F0–F4 equivalent scale; APRI and FIB-4 scores at the time of biopsy were then mapped to the same scale.Results. We identified 2372 liver biopsies from HCV-infected patients with contemporaneous laboratory values for imputing APRI and FIB-4. Fibrosis stage distributions by the equivalent biopsy scale were 267 (11%) F0; 555 (23%) F1; 648 (27%) F2; 394 (17%) F3; and 508 (21%) F4. Mean APRI and FIB-4 values significantly increased with successive fibrosis levels (P < .05). The areas under the receiver operating characteristic curve (AUROC) analysis distinguishing severe (F3–F4) from mild-to-moderate fibrosis (F0–F2) were 0.80 (95% confidence interval [CI], .78–.82) for APRI and 0.83 (95% CI, .81–.85) for FIB-4. There was a significant difference between the AUROCs of FIB-4 and APRI (P < .001); 88% of persons who had a FIB-4 score ≥2.0 were at stage F2 or higher.Conclusions. In a large observational cohort, FIB-4 was good at differentiating 5 stages of chronic HCV infection. It can be useful in screening patients who need biopsy and therapy, for monitoring patients with less advanced disease, and for longitudinal studies. [ABSTRACT FROM PUBLISHER]

Targeted screening is “cost-effective” when prevalence of hepatitis C virus exceeds 0.84%. Prospective evaluation of a screening tool is warranted and should include comparisons with other screening strategies.Background. Hepatitis C virus (HCV) is the most common chronic blood-borne infection in the United States and will become an increasing source of morbidity and mortality with aging of the infected population. Our objective was to develop decision analytic models to explore the cost-effectiveness of screening in populations with varying prevalence of HCV and risks for fibrosis progression.Methods. We developed a Markov state transition model to examine screening of an asymptomatic community-based population in the United States. The base case was an ethnically and gender-mixed adult population with no prior knowledge of HCV status. Interventions were screening followed by guideline-based treatment, or no screening. Effectiveness was measured in quality-adjusted life-years (QALYs), and costs were measured in 2011 US dollars.Results. In the base case (US population, 49% male, 78% white, 13% African American, and 9% Hispanic, mean age, 46 years), screening followed by guideline-based treatment (using boceprevir as the direct-acting antiviral agent) of those with chronic HCV infection costs $47 276 per QALY. The overall HCV prevalence in the United States is reported to be 1.3%–1.9%, but prevalence varies markedly among patients with different numbers and types of risk factors. The marginal cost-effectiveness ratio (mCER) of screening decreases as prevalence increases. Below a prevalence of 0.84%, the mCER is greater than the generally accepted societal willingness-to-pay threshold of $50 000 per QALY and thus is not considered highly cost-effective.Conclusions. Targeted screening is cost-effective when prevalence of HCV exceeds 0.84%. Prospective evaluation of a screening tool is warranted and should include comparisons with other screening strategies.

Baseline demographic, clinical, and mortality data from the Chronic Hepatitis Cohort Study utilize the electronic health records of >2200 chronic hepatitis B virus and 8800 chronic hepatitis C virus patients from 4 integrated healthcare systems and highlight the substantial US health burden from chronic viral hepatitis.Background. The Chronic Hepatitis Cohort Study (CHeCS), a dynamic prospective, longitudinal, observational cohort study, was created to assess the clinical impact of chronic viral hepatitis in the United States. This report describes the cohort selection process, baseline demographics, and insurance, biopsy, hospitalization, and mortality rates.Methods. Electronic health records of >1.6 million adult patients seen from January 2006 through December 2010 at 4 integrated healthcare systems in Detroit, Michigan; Danville, Pennsylvania; Portland, Oregon; and Honolulu, Hawaii were collected and analyzed.Results. Of 2202 patients with chronic hepatitis B virus (HBV) infection, 50% were aged 44–63 years, 57% male, 58% Asian/Pacific Islander, and 13% black; and 5.1% had Medicaid, 16.5% Medicare, and 76.3% private insurance. During 2001–2010, 22.3% had a liver biopsy and 37.9% were hospitalized. For the 8810 patients with chronic hepatitis C virus (HCV) infection, 75% were aged 44–63 years, 60% male, 23% black; and 12% had Medicaid, 23% Medicare, and 62% private insurance. During 2001–2010, 38.4% had a liver biopsy and 44.3% were hospitalized. Among persons in care, 9% of persons with HBV and 14% of persons with HCV infection, mainly those born during 1945–1964, died during the 2006–2010 five-year period.Conclusions. Baseline demographic, hospitalization, and mortality data from CHeCS highlight the substantial US health burden from chronic viral hepatitis, particularly among persons born during 1945–1964.

Even among persons with access to care, many with 2 or more elevated ALT levels were not tested for HBV or HCV infection. Asian race and being middle-aged were independently associated with testing positive for HBV and HCV infection, respectively.Background. Little is known about viral hepatitis testing and infection prevalence among persons in private healthcare organizations (HCOs) in the United States.Methods. To determine the frequency of and characteristics associated with viral hepatitis testing and infection prevalence among adults with access to care, we conducted an observational cohort study among 1.25 million adults from 4 US HCOs and included persons with ≥1 clinical encounter during 2006–2008 and ≥12 months of continuous follow-up before 2009. We compared the number of infections identified with the number expected based on adjusted data from the National Health and Nutrition Examination Survey (NHANES).Results. Of 866 886 persons without a previous hepatitis B virus (HBV) diagnosis, 18.8% were tested for HBV infection, of whom 1.4% tested positive; among 865 659 without a previous hepatitis C virus (HCV) diagnosis, 12.7% were tested, of whom 5.5% tested positive. Less than half of those with ≥2 abnormal alanine aminotransferase (ALT) levels were subsequently tested for HBV or HCV. When tested, Asians (adjusted odds ratio [aOR] 6.33 relative to whites) were most likely HBV infected, whereas those aged 50–59 years were most likely HCV infected (aOR 6.04, relative to age <30 years). Based on estimates from NHANES, nearly one-half of HCV and one-fifth of HBV infections in this population were not identified.Conclusions. Even in this population with access to care and lengthy follow-up, only a fraction of expected viral hepatitis infections were identified. Abnormal ALT levels often but not consistently triggered testing. These findings have implications for the identification and care of 4–5 million US residents with HBV and HCV infection.

Background Trends in the epidemiology of chronic hepatitis B (CHB) among routine clinical care patients in the United States are not well documented. We used data from the Chronic Hepatitis Cohort Study to investigate changes in prevalence and newly recorded cases of CHB from 2006 to 2015. Methods Annual percentage changes (APCs) were estimated using join point Poisson regression. Analyses were adjusted by study site; when an interaction with the trend was observed, APCs were estimated by subgroups. Differences in rates based on race, age, and sex were calculated with rate ratios. Results We identified 5492 patients with CHB within select health systems with total populations that ranged from 1.9 to 2.4 million persons. From 2006 to 2014, the prevalence of diagnosed CHB increased from 181.3 to 253.0 per 100 000 persons in the health system population; from 2014 to 2015, it declined to 237.0 per 100 000 persons. APC was +3.7%/y through 131 December 2014 (P <.001) and −15.0%/y (P <.001) thereafter. The rate of newly reported cases of CHB did not change significantly across the study period (APC, −1.1%/y; P =.07). The rates of newly reported cases were 20.5 times higher among patients in the Asian American/American Indian/Pacific Islander (ASINPI) category, compared with white patients, and 2.8 times higher among African American patients. The ratio of male to female patients was roughly 3:2. Conclusions The prevalence of diagnosed CHB in this US patient population increased from 2006 to 2014, after which it decreased significantly. Rates declined most rapidly among patients ≤40 or 61–70 years old, as well as among ASINPI patients. The rate of newly reported cases remained steady over the study period. [ABSTRACT FROM AUTHOR]
