Hepatocellular carcinoma in patients cured of chronic hepatitis C: Minimal steatosis.

BACKGROUND: Successful treatment of hepatitis C reduces liver inflammation and fibrosis; however, patients remain at risk of developing hepatocellular carcinoma (HCC). AIMS: To identify risk factors for new-onset HCC in patients cured of hepatitis C. METHODS: Imaging, histological, and clinical data on patients whose first HCC was diagnosed >12 months of post-SVR were analyzed. Histology of 20 nontumor tissues was analyzed in a blinded manner using the Knodel/Ishak/HAI system for necroinflammation and fibrosis/cirrhosis stage and the Brunt system for steatosis/steatohepatitis. Factors associated with post-SVR HCC were identified by comparison with HALT-C participants who did not develop post-SVR HCC. RESULTS: Hepatocellular carcinoma was diagnosed in 54 patients (45 M/9F), a median of 6 years of post-SVR [interquartile range (IQR) =1.4-10y] at a median age of 61 years (IQR, 59-67). Approximately one-third lacked cirrhosis, and only 11% had steatosis on imaging. The majority (60%) had no steatosis/steatohepatitis in histopathology. The median HAI score was 3 (1.25-4), indicating mild necroinflammation. In a multivariable logistic regression model, post-SVR HCC was positively associated with non-Caucasian race (p = 0.03), smoking (p = 0.03), age > 60 years at HCC diagnosis (p = 0.03), albumin<3.5 g/dL (p = 0.02), AST/ALT>1 (p = 0.05), and platelets <100 × 103 cells/µL (p < 0.001). Alpha fetoprotein ≥4.75 ng/mL had 90% specificity and 71% sensitivity for HCC occurrence. Noncirrhotic patients had larger tumors (p = 0.002) and a higher prevalence of vascular invasion (p = 0.016) than cirrhotic patients. CONCLUSIONS: One-third of patients with post-SVR HCC did not have liver cirrhosis; most had no steatosis/steatohepatitis. Hepatocellular carcinomas were more advanced in noncirrhotic patients. Results support AFP as a promising marker of post-SVR HCC risk.

Hepatocellular carcinoma surveillance, incidence, and tumor doubling times in patients cured of hepatitis C.

BACKGROUND: Hepatocellular carcinoma (HCC) incidence and mortality vary by race/ethnicity and both are higher in Black patients than in Whites. For HCC surveillance, all cirrhotic patients are advised to undergo lifelong twice-annual abdominal imaging. We investigated factors associated with surveillance and HCC incidence in a diverse HCC risk group, cirrhotic patients recently cured of hepatitis C virus (HCV) infection. METHODS: In this observational cohort study, all participants (n = 357) had advanced fibrosis/cirrhosis and were cured of HCV with antiviral treatment. None had Liver Imaging Reporting and Data System (LI-RADS) 2-5 lesions prior to HCV cure. Ultrasound, computed tomography, and/or magnetic resonance imaging were used for surveillance. RESULTS: At a median follow-up of 40 months [interquartile range (IQR) = 28-48], the median percentage of time up-to-date with surveillance was 49% (IQR) = 30%-71%. The likelihood of receiving a first surveillance examination was not significantly associated with race/ethnicity, but was higher for patients with more advanced cirrhosis, for example, bilirubin [odds ratio (OR) = 3.8/mg/dL, p = 0.002], private insurance (OR = 3.4, p = 0.006), and women (OR = 2.3, p = 0.008). The likelihood of receiving two or three examinations was significantly lower for non-Hispanic Blacks and Hispanics versus non-Hispanic Whites (OR = 0.39, and OR = 0.40, respectively, p < 0.005 for both) and for patients with higher platelet counts (OR = 0.99/10,000 cells/µl, p = 0.01), but higher for patients with private insurance (OR = 2.8, p < 0.001). Incident HCC was associated with higher bilirubin (OR = 1.7, p = 0.02) and lower lymphocyte counts (OR = 0.16, p = 0.01). CONCLUSIONS: Contrary to best practices, HCC surveillance was associated with sociodemographic factors (insurance status and race/ethnicity) among patients cured of HCV. Guideline-concordant surveillance is needed to address healthcare disparities.

Innovations in Hepatitis C Screening and Treatment.

New therapies offer hope for a cure to millions of persons living with hepatitis C virus (HCV) infection. HCV elimination is a global goal that will be difficult to achieve using the traditional paradigms of diagnosis and care. The current standard has evolved toward universal HCV screening and treatment, to achieve elimination goals. There are several steps between HCV diagnosis and cure with major barriers along the way. Innovative models of care can address barriers to better serve hardly reached populations and scale national efforts in the United States and abroad. Herein, we highlight innovative models of HCV care that aid in our progress toward HCV elimination.

Liver Injury in Patients Hospitalized with Coronavirus Disease 2019 Correlates with Hyperinflammatory Response and Elevated Interleukin-6.

Liver injury is commonly seen in coronavirus disease 2019 (COVID-19); however, the mechanism behind liver injury, particularly in patients with severe and critical COVID-19, remains unclear, and the clinical course is poorly described. We conducted a single-center retrospective cohort study of consecutive patients hospitalized with severe and critical COVID-19 with or without liver injury and who underwent immunologic testing (interleukin [IL]-6, IL-8, tumor necrosis factor alpha [TNF-α], and IL-1ß). Liver injury was defined as peak aminotransferases ≥3 times the upper limit of normal (40 U/L) or ≥120 U/L. Patients with liver injury were compared to those who had normal aminotransferases throughout the hospital course. We studied 176 patients: 109 with liver injury and 67 controls. Patients with liver injury were more likely to be men (71.6% vs. 37.3%, P < 0.001). Peak inflammatory markers and IL-6 were higher in the liver injury group: C-reactive protein (CRP), 247 vs. 168 mg/L, P < 0.001; lactate dehydrogenase (LDH), 706 vs. 421 U/L; ferritin, 2,973 vs. 751 ng/mL, P < 0.001; IL-6, 121.0 vs. 71.8 pg/mL, P < 0.001. There was no difference in the levels of IL-8, TNF-α, and IL-1ß. The liver injury group had a longer length of stay in the hospital and more severe COVID-19 despite having less diabetes and chronic kidney disease. Conclusion: An exaggerated hyperinflammatory response (cytokine storm) characterized by significantly elevated CRP, LDH, ferritin, and IL-6 levels and increasing severity of COVID-19 appears to be associated with the occurrence of liver injury in patients with severe/critical COVID-19.

Outcomes following SARS-CoV-2 infection in liver transplant recipients: an international registry study.

BACKGROUND: Despite concerns that patients with liver transplants might be at increased risk of adverse outcomes from COVID-19 because of coexisting comorbidities and use of immunosuppressants, the effect of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection on this patient group remains unclear. We aimed to assess the clinical outcomes in these patients. METHODS: In this multicentre cohort study, we collected data on patients with laboratory-confirmed SARS-CoV-2 infection, who were older than 18 years, who had previously received a liver transplant, and for whom data had been submitted by clinicians to one of two international registries (COVID-Hep and SECURE-Cirrhosis) at the end of the patient's disease course. Patients without a known hospitalisation status or mortality outcome were excluded. For comparison, data from a contemporaneous cohort of consecutive patients with SARS-CoV-2 infection who had not received a liver transplant were collected from the electronic patient records of the Oxford University Hospitals National Health Service Foundation Trust. We compared the cohorts with regard to several outcomes (including death, hospitalisation, intensive care unit [ICU] admission, requirement for intensive care, and need for invasive ventilation). A propensity score-matched analysis was done to test for an association between liver transplant and death. FINDINGS: Between March 25 and June 26, 2020, data were collected for 151 adult liver transplant recipients from 18 countries (median age 60 years [IQR 47-66], 102 [68%] men, 49 [32%] women) and 627 patients who had not undergone liver transplantation (median age 73 years [44-84], 329 [52%] men, 298 [48%] women). The groups did not differ with regard to the proportion of patients hospitalised (124 [82%] patients in the liver transplant cohort vs 474 [76%] in the comparison cohort, p=0·106), or who required intensive care (47 [31%] vs 185 [30%], p=0·837). However, ICU admission (43 [28%] vs 52 [8%], p<0·0001) and invasive ventilation (30 [20%] vs 32 [5%], p<0·0001) were more frequent in the liver transplant cohort. 28 (19%) patients in the liver transplant cohort died, compared with 167 (27%) in the comparison cohort (p=0·046). In the propensity score-matched analysis (adjusting for age, sex, creatinine concentration, obesity, hypertension, diabetes, and ethnicity), liver transplantation did not significantly increase the risk of death in patients with SARS-CoV-2 infection (absolute risk difference 1·4% [95% CI -7·7 to 10·4]). Multivariable logistic regression analysis showed that age (odds ratio 1·06 [95% CI 1·01 to 1·11] per 1 year increase), serum creatinine concentration (1·57 [1·05 to 2·36] per 1 mg/dL increase), and non-liver cancer (18·30 [1·96 to 170·75]) were associated with death among liver transplant recipients. INTERPRETATION: Liver transplantation was not independently associated with death, whereas increased age and presence of comorbidities were. Factors other than transplantation should be preferentially considered in relation to physical distancing and provision of medical care for patients with liver transplants during the COVID-19 pandemic.

Response to 'hepatitis C cure improved patient-reported outcomes in patients with and without liver fibrosis in a prospective study at a large urban medical center'.

Patient-reported outcomes (PROs) are important measures of quality of life. Direct-acting antiviral (DAA) drugs for hepatitis C virus (HCV) improved PROs in clinical trials. We prospectively evaluated the impact of DAA-based HCV cure on PROs and liver-related outcomes in real-world patients at a large urban medical centre. The Short Form (SF)-36 and three additional validated instruments were used. F3-4 fibrosis was defined as >9.6 kPa by transient elastography (TE); S2-3 steatosis was defined as >270 dB/m by TE-controlled attenuation parameter (CAP). Data were analysed by paired and unpaired t tests. Patients (n = 16) who did not achieve a sustained virologic response at 12 weeks (SVR12) were excluded. The study achieved its primary endpoint and showed a significant 30% improvement in the SF-36 vitality score, measured baseline to SVR12: 63 vs 82, P < .001 (n = 111). Scores in 24 of 25 PRO domains improved at SVR12 (P < .05). Nearly all gains exceeded 5%, indicating their clinical significance. Transaminase values and liver stiffness improved (decreased) significantly, baseline to SVR12 (p<0.005), but steatosis was unchanged (p=0.58). Patients with baseline F0-2 fibrosis and those with F3-F4 fibrosis both improved in 22 domains. Patients with baseline S0-S1 steatosis improved in more domains (23) than patients with S2-S3 steatosis (19). At baseline, patients with F3-F4 fibrosis and patients with S2-3 steatosis had worse scores in certain PRO domains than patients with F0-2 fibrosis or S0-S1 steatosis, but this difference resolved by SVR12. HCV cure led to meaningful gains in PROs, and these findings may encourage patients to seek treatment.

Elevated prevalence of moderate-to-severe hepatic steatosis in World Trade Center General Responder Cohort in a program of CT lung screening.

BACKGROUND AND AIMS: To determine the prevalence of moderate-to-severe hepatic steatosis (HS) and associated risk factors in members of the World Trade Center (WTC) General Responder Cohort (GRC) who qualify for low-dose non-contrast computed tomography for lung cancer screening and compare them to non-WTC participants in the same screening program. METHODS: All participants gave written informed consent before participating in this IRB-approved study. Clinical variables and laboratory values were recorded. Hepatic attenuation measurement (Hounsfield unit; HU) was measured on low-dose computed tomography (LDCT) and a threshold attenuation value <40HU indicated moderate-to-severe HS. Bivariate and multivariable linear and logistic regression analyses were performed. Propensity scores (PS) were calculated and inverse probability weighting (IPW) was used to adjust for potential confounders when comparing the WTC with non-WTC participants. RESULTS: The prevalence of moderate-to-severe HS was 16.2% among 154 WTC participants compared to 5.3% among 170 non-WTC participants. In WTC members, moderate-to-severe HS was associated with higher BMI, higher laboratory liver function tests, and former smoking status. Using PS analysis and IPW to account for potential confounders, the odds ratio for moderate-to-severe HS was 3.4-fold higher (95% confidence interval: 1.7-6.7) in the WTC participants compared with non-WTC participants. Moderate-to-severe HS was also associated with higher BMI and former smoker status. CONCLUSION: Prevalence of moderate-to-severe HS was >3-fold higher in the WTC-GRC group than in other participants.

Provider Attitudes and Practice Patterns for Direct-Acting Antiviral Therapy for Patients With Hepatocellular Carcinoma.

BACKGROUND & AIMS: Direct-acting antivirals (DAAs) are effective against hepatitis C virus and sustained virologic response is associated with reduced incidence of hepatocellular carcinoma (HCC). However, there is controversy over the use of DAAs in patients with active or treated HCC and uncertainty about optimal management of these patients. We aimed to characterize attitudes and practice patterns of hepatology practitioners in the United States regarding the use of DAAs in patients with HCC. METHODS: We conducted a survey of hepatology providers at 47 tertiary care centers in 25 states. Surveys were sent to 476 providers and we received 279 responses (58.6%). RESULTS: Provider beliefs about risk of HCC recurrence after DAA therapy varied: 48% responded that DAAs reduce risk, 36% responded that DAAs do not change risk, and 16% responded that DAAs increase risk of HCC recurrence. However, most providers believed DAAs to be beneficial to and reduce mortality of patients with complete response to HCC treatment. Accordingly, nearly all providers (94.9%) reported recommending DAA therapy to patients with early-stage HCC who received curative treatment. However, fewer providers recommended DAA therapy for patients with intermediate (72.9%) or advanced (57.5%) HCC undergoing palliative therapies. Timing of DAA initiation varied among providers based on HCC treatment modality: 49.1% of providers reported they would initiate DAA therapy within 3 months of surgical resection whereas 45.9% and 5.0% would delay DAA initiation for 3-12 months and >1 year post-surgery, respectively. For patients undergoing transarterial chemoembolization (TACE), 42.0% of providers would provide DAAs within 3 months of the procedure, 46.7% would delay DAAs until 3-12 months afterward, and 11.3% would delay DAAs more than 1 year after TACE. CONCLUSIONS: Based on a survey sent to hepatology providers, there is variation in provider attitudes and practice patterns regarding use and timing of DAAs for patients with HCC. Further studies are needed to characterize the risks and benefits of DAA therapy in this patient population.

Automated measurement of liver attenuation to identify moderate-to-severe hepatic steatosis from chest CT scans.

PURPOSE: Develop and validate an automated method for measuring liver attenuation in non-contrast low-dose chest CT (LDCT) scans and compare it to the standard manual method for identifying moderate-to-severe hepatic steatosis (HS). METHOD: The automated method identifies a region below the right lung within the liver and uses statistical sampling techniques to exclude non-liver parenchyma. The method was used to assess moderate-to-severe HS on two IRB-approved cohorts: 1) 24 patients with liver disease examined between 1/2013-1/2017 with non-contrast chest CT and abdominal MRI scans obtained within three months of liver biopsy, and 2) 319 lung screening participants with baseline LDCT performed between 8/2011-1/2017. Agreement between the manual and automated CT methods, the manual MRI method, and pathology for determining moderate-to-severe HS was assessed using Cohen's Kappa by applying a 40 HU threshold to the CT method and 17.4% fat fraction to MRI. Agreement between the manual and automated CT methods was assessed using the intraclass correlation coefficient (ICC). Variability was assessed using Bland-Altman limits of agreement (LoA). RESULTS: In the first cohort, the manual and automated CT methods had almost perfect agreement (ICC = 0.97, κ = 1.00) with LoA of -7.6 to 4.7 HU. Both manual and automated CT methods had almost perfect agreement with MRI (κ = 0.90) and substantial agreement with pathology (κ = 0.77). In the second cohort, the manual and automated CT methods had almost perfect agreement (ICC = 0.94, κ = 0.87). LoA were -10.6 to 5.2 HU. CONCLUSION: Automated measurements of liver attenuation from LDCT scans can be used to identify moderate-to-severe HS on LDCT.

Hepatitis C cure improved patient-reported outcomes in patients with and without liver fibrosis in a prospective study at a large urban medical center.

Patient-reported outcomes (PROs) are important measures of quality of life. Direct-acting antiviral (DAA) drugs for hepatitis C virus (HCV) improved PROs in clinical trials. We prospectively evaluated the impact of DAA-based HCV cure on PROs and liver-related outcomes in real-world patients at a large urban medical center. The short form (SF)-36 and three additional validated instruments were used.

Data were analysed by paired and unpaired t tests. Patients (n = 16) who did not achieve a sustained virologic response at 12 weeks (SVR12) were excluded. The study achieved its primary endpoint and showed a significant 30% improvement in the SF-36 vitality score, measured baseline to SVR12: 63 versus 82, P < .001 (n = 111).

Patients with baseline S0-S1 steatosis improved in more domains (23) than patients with S2-S3 steatosis (19). At baseline, patients with F3-F4 fibrosis and patients with S2-3 steatosis had worse scores in certain PRO domains than patients with F0-2 fibrosis or S0-S1 steatosis, but this difference resolved by SVR12. HCV cure led to meaningful gains in PROs, and these findings may encourage patients to seek treatment.

Liver Cancer Disparities in New York City: A Neighborhood View of Risk and Harm Reduction Factors.

INTRODUCTION: Liver cancer is the fastest increasing cancer in the United States and is one of the leading causes of cancer-related death in New York City (NYC), with wide disparities among neighborhoods. The purpose of this cross-sectional study was to describe liver cancer incidence by neighborhood and examine its association with risk factors. This information can inform preventive and treatment interventions. MATERIALS AND METHODS: Publicly available data were collected on adult NYC residents (n = 6,407,022). Age-adjusted data on liver and intrahepatic bile duct cancer came from the New York State Cancer Registry (1) (2007-2011 average annual incidence); and the NYC Vital Statistics Bureau (2015, mortality). Data on liver cancer risk factors (2012-2015) were sourced from the New York City Department of Health and Mental Hygiene: (1) Community Health Survey, (2) A1C registry, and (3) NYC Health Department Hepatitis surveillance data. They included prevalence of obesity, diabetes, diabetic control, alcohol-related hospitalizations or emergency department visits, hepatitis B and C rates, hepatitis B vaccine coverage, and injecting drug use. RESULTS: Liver cancer incidence in NYC was strongly associated with neighborhood poverty after adjusting for race/ethnicity (ß = 0.0217, p = 0.013); and with infection risk scores (ß = 0.0389, 95% CI = 0.0088-0.069, p = 0.011), particularly in the poorest neighborhoods (ß = 0.1207, 95% CI = 0.0147-0.2267, p = 0.026). Some neighborhoods with high hepatitis rates do not have a proportionate number of hepatitis prevention services. CONCLUSION: High liver cancer incidence is strongly associated with infection risk factors in NYC. There are gaps in hepatitis prevention services like syringe exchange and vaccination that should be addressed. The role of alcohol and metabolic risk factors on liver cancer in NYC warrants further study.

Reducing Liver Cancer Risk in African-Born Immigrants Through Culturally Targeted Hepatitis B Group Education Programs.

Of 900 West African-born immigrants living in New York City who were tested for hepatitis B virus (HBV), over 9% were found to have the infection (Shankar H et al. Clin Infectious Dis 62(S4):S289-s297, 2016). Community targeted group education programs (EP) have been shown to improve immigrant population's health (Bailey E et al. J Natl Med Assoc 92(3):136-42, 2000). Our aim is to enhance HBV screening in at-risk West African immigrants through the development of a group EP as a first critical step to reducing liver cancer risk. The framework for an HBV group EP was created based on our prior work to identify barriers and facilitators for HBV screening in this community (Sriphanlop, P et al. Am J Health Behav 5(10):745-754, 2014). The framework was then refined with input from community "gatekeepers" or leaders (n = 57) through four focus groups. After refining the group EP, we then pilot tested the EP with 154 participants from eight different West African communities with a pre-/post-test HBV knowledge survey assessment to determine the impact of the group EP. Results from the pre-/post-test survey assessment demonstrated a significant increase in HBV knowledge after the EP (70% pre-test vs. 88% post-test, p value <.01). Through a community-based participatory approach, a group EP could be effective in increasing knowledge about HBV infection and HBV screening as a first step to reducing liver cancer risk.

A Novel Collaborative Community-Based Hepatitis B Screening and Linkage to Care Program for African Immigrants.

BACKGROUND: Sub-Saharan African nations have among the highest rates of chronic hepatitis B virus (HBV) infection worldwide, but little is known about HBV infection in African-born persons in the United States. METHODS: From October 2011 to July 2013, community-based HBV screenings were conducted targeting persons originating from Africa in New York City. Persons were identified as currently HBV infected (HBsAg positive) or exposed (HBcAb positive). RESULTS: Overall, 955 persons were screened for HBV; the median age was 45 years (interquartile range, 35-54 years) and 75.5% were men. Of these, 919 persons had no history of liver disease, of whom 9.6% (n = 88) had current HBV infection and 73.9% (n = 679) had exposure. In logistic regression, older age (odds ratio [OR], 0.97; 95% confidence interval [CI], .94-.99; P < .01) and female sex (OR, 0.35; 95% CI, .14-.75; P < .01) were less likely to be associated with HBV infection, whereas having a mother with hepatitis was associated with infection (OR, 18.8; 95% CI, 2.72-164.65; P < .01). HBV exposure was associated with older age (OR, 1.03; 95% CI, 1.01-1.04; P < .01), whereas female sex (OR, 0.46; 95% CI, .33-.66; P < .01) and history of blood transfusion (OR, 0.43; 95% CI, .22-.83; P = .01) were negatively associated. A patient navigator linked 97% of infected persons to care. Eleven persons were recommended for treatment, of whom 9 (82%) started therapy. Three persons were diagnosed with hepatocellular carcinoma on the first screening ultrasound. CONCLUSIONS: The high burden of HBV infection among African immigrants in the United States underscores a need for continued screening and linkage to care in this at-risk population.

Adapting the Andersen model to a francophone West African immigrant population: hepatitis B screening and linkage to care in New York City.

Hepatitis B virus (HBV) is highly endemic in West Africa and immigration from this region to the United States has greatly increased over the past quarter century. Using the Andersen Model as a conceptual framework, this study qualitatively examines francophone West African immigrants' perceptions of factors affecting access to HBV screening and linkage-to-care in New York City. Four focus groups were conducted with 39 purposefully selected participants. The focus groups were conducted in French, audio-recorded, translated into English, transcribed, analyzed, and coded for major themes. Participants identified increasing knowledge of HBV and opportunities to access care in a culturally-sensitive manner that decreases fatalism and avoids generating stigma as priorities. They also emphasized the importance of engaging religious establishments and social networks and employing the Internet to disseminate HBV-relevant information. Cost and health insurance are identified as future challenges that will need to be addressed in a health care environment in which undocumented immigrants are ineligible for health insurance. The qualitative analysis in this study highlights the recursive and interdependent nature of the Andersen Model, and a modification of the model is proposed that is intended to inform examinations of other minority communities' access to health care.

Severe ductopenia and cholestasis from levofloxacin drug-induced liver injury: a case report and review.

A 67-year-old woman with hypertension, hypothyroidism, and glaucoma was referred for jaundice and elevated liver function tests. She was treated for streptococcal endophthalmitis with 2 weeks of intravenous (IV) levofloxacin followed by 2 months of oral levofloxacin. The patient had no prior history of liver disease and denied alcohol intake. Her physical exam was remarkable for jaundice and scleral icterus without any stigmata of liver disease. Viral hepatitis serologies and antibodies, including myeloperoxidase, proteinase 3, and antinuclear, antimitochondrial, antiliver kidney microsome, antismooth muscle antibodies, were all within normal limits. The liver biopsy revealed severe cholestasis, extensive bile duct loss, and fibrosis. The patient had no known exposure to any other systemic medications or inciting factors other than levofloxacin. Although there are a few reported cases of drug-induced liver disease (DILI) related to levofloxacin, this case is believed to be the first reported case of ductopenia or vanishing bile duct syndrome (VBDS) associated with levofloxacin. Although fluoroquinolones, such as levofloxacin, are generally considered safe antibiotics, health practitioners must be aware of their association with DILI, as the diagnosis of DILI is one of exclusion and requires a high index of suspicion.

Voices of multi-ethnic providers in NYC: health care for viral hepatitis to prevent hepatocellular carcinoma.

Worldwide, hepatocellular carcinoma (HCC) is the third leading cause of cancer deaths and the ninth in the US. Hepatitis B and C make up almost 80% of HCC cases. Based on our Hepatitis Outreach Network screening program data, approximately 40% of at-risk foreign-born community members who tested positive for viral hepatitis B and/or C did not follow up for additional care. Our aim was to use theory-driven qualitative research to identify barriers and facilitators to follow-up after viral hepatitis diagnosis among these community members from the viewpoint of primary care providers (PCPs). As viral hepatitis is a precursor of liver cancer, timely treatment of the virus has the potential to reduce the incidence and burden of liver cancer. We performed semi-structured key informant interviews with 20 primary care physicians who predominantly serve Korean, Chinese, Egyptian, and Russian communities. Barriers detected included cultural factors commonly seen amongst immigrant populations such as busy work schedules and non-English language. Common facilitators include increased primary care physician involvement and linkages to care within communities in which patients reside. Providers perceived that they are gatekeepers to specialty care for their patients and therefore key persons to engage in viral hepatitis evaluation and management by specialists. This initial study suggests that re-focusing energy into primary care physicians might offer promise for improved care for individuals from immigrant communities who have viral hepatitis to help them engage in care and thereby reduce the burden of liver cancer.

Hepatitis C screening beyond CDC guidelines in an Egyptian immigrant community.

BACKGROUND & AIMS: Many Egyptian-born persons in the U.S. are at high risk of chronic hepatitis C virus (HCV) infection, yet are not aware of their infection and lack healthcare coverage or linkage to care. In this study, we target Egyptian-born persons living in the New York City area for screening and link to care. METHODS: A unique partnership, the Hepatitis Outreach Network (HONE), combines the expertise and resources of the Mount Sinai School of Medicine, the NYC Department of Health and Mental Hygiene and community-based organizations, to provide education, screening and link to care in communities with high prevalence of chronic viral hepatitis. RESULTS: Through four community-based screening events, 192 Egyptian-born persons were screened for HCV. Thirty (15.6%) persons were HCV positive. HCV antibody prevalence in those, whose national origin was Egypt, increased strongly with age and was associated with increasing number of years resident in Egypt and rural residents. Of the 30 Egyptian persons with HCV infection, 18 (60%) received a medical evaluation (2 with local providers and 16 at Mount Sinai). Of the HCV-infected persons evaluated, treatment was recommended in four and begun in three (75%). CONCLUSION: Egyptian-born persons living in the New York City area have a high burden of HCV disease. HONE has successfully established targeted HCV screening in Egyptian-born persons through use of several unique elements that effectively link them to care.

Hepatitis Outreach Network: a practical strategy for hepatitis screening with linkage to care in foreign-born communities.

BACKGROUND & AIMS: Many foreign-born persons in the US are at high risk of chronic hepatitis B (HBV) and C (HCV) infections, yet are not aware of their infection, and lack healthcare coverage or linkage to care. METHODS: A unique partnership, the Hepatitis Outreach Network, combines the expertise and resources of the Mount Sinai School of Medicine, the NYC Department of Health and Mental Hygiene, and community-based organizations, to provide education, screening and link to care in communities with high prevalence of chronic viral hepatitis. Comprehensive HBV and HCV screening identifies infected patients, who then receive further evaluation from either local or Mount Sinai physicians, combined with patient-navigators who organize follow-up visits. RESULTS: Of 1603 persons screened, 76 had HBV and 75 had HCV. Importantly, screening for HCV based on traditional risk factors would have missed 67% of those who tested positive. Of the 76 persons with HCV infection, 49 (64%) received a medical evaluation (26 with local providers and 23 at Mount Sinai). Of the 49 HCV-infected persons evaluated, treatment was recommended in 11 and begun in 8 (73%). Of the 76 persons with HBV infection, 43 (57%) received a medical evaluation (31 with local providers and 12 at Mount Sinai). Of the 43 HBV-infected persons evaluated, treatment was recommended and begun in 5 (100%). CONCLUSIONS: Hepatitis Outreach Network has successfully established novel proof of concept for identifying HBV and HCV infections in foreign-born persons through use of several unique elements that effectively link them to care.
