Background: Chronic hepatitis B virus (HBV) and hepatitis C virus (HCV) infections are known risk factors for liver disease, cirrhosis and hepatocellular carcinoma (HCC). There is substantial global variation in HBV and HCV prevalence resulting in variations in cirrhosis and HCC. We previously reported high prevalence of HBV and HCV infections in Somali immigrants seen at an academic medical center in Minnesota., Aim: To determine the prevalence of chronic viral hepatitis in Somali immigrants in Minnesota through a community-based screening program., Methods: We conducted a prospective community-based participatory research study in the Somali community in Minnesota in partnership with community advisory boards, community clinics and local mosques between November 2010 and December 2015 (data was analyzed in 2020). Serum was tested for hepatitis B surface antigen, hepatitis B core antibody, hepatitis B surface antibody and anti-HCV antibody., Results: Of 779 participants, 15.4% tested positive for chronic HBV infection, 50.2% for prior exposure to HBV and 7.6% for chronic HCV infection. Calculated age-adjusted frequencies in males and females for chronic HBV were 12.5% and 11.6%; for prior exposure to HBV were 44.8% and 41.3%; and for chronic HCV were 6.7% and 5.7%, respectively. Seven participants developed incident HCC during follow up., Conclusion: Chronic HBV and HCV are major risk factors for liver disease and HCC among Somali immigrants, with prevalence of both infections substantially higher than in the general United States population. Community-based screening is essential for identifying and providing health education and linkage to care for diagnosed patients., Competing Interests: Conflict-of-interest statement: All the authors report no relevant conflicts of interest for this article., (©The Author(s) 2022.

Background and Aims: Hepatitis C virus (HCV) treatment has changed dramatically in the last few years. Our observations suggest that a minority of HCV infected Somalis are treated. In this study, we aimed to evaluate for treatment and health outcome disparities between Somali and non-Somali patients during the direct acting antiviral (DAA) era., Methods: Patients with HCV seen in the gastroenterology clinic in 2015 were included in the study. Patients were identified using ICD9 and 10 codes. Electronic medical records were analyzed to evaluate for treatment candidacy, acceptance and reasons for refusal of treatment., Results: Genotype 4 followed by 3 were the most common genotypes in the Somalis while genotype 1 was the most common in the non-Somalis. Majority of patients were offered treatment, active alcohol and substance abuse was a common reason for not offering treatment in non-Somalis while the presence of hepatocellular carcinoma was the most common reason in Somalis. Somalis had higher rates of declining treatment given the asymptomatic nature of their disease and the feeling that treatment is not needed. Sustained virologic response rates were comparable in both groups., Conclusions: Disparities in acceptance of HCV treatment persist in the DAA era. The asymptomatic nature of the infection and potential cultural mistrust makes patients hesitant to undergo treatment. Healthcare providers must find interventions aimed at reducing barriers to treatment and increasing acceptance of HCV treatment., (Copyright © 2018 National Medical Association.

Objective: To study the frequencies of chronic hepatitis B virus (HBV) and hepatitis C virus (HCV) infection, and their associations with hepatocellular carcinoma (HCC) in immigrant Somalis seen at Mayo Clinic in Rochester, Minnesota., Patients and Methods: We determined the frequencies of HBV and HCV infection and HCC in immigrant Somalis seen at Mayo Clinic from July 1, 1996, through October 31, 2009. Non-Somali Olmsted County residents served as controls., Results: For Somali males and females, age-adjusted proportions (per 1000 population) were 209 and 123 for hepatitis B surface antigen (HBsAg), 644 and 541 for hepatitis B core antibody (HBcAb), and 99 and 66 for anti-HCV. The comparative proportions in non-Somalis were 20 and 9 for HBsAg, 126 and 97 for HBcAb, and 32 and 17 for anti-HCV. Hepatitis C virus RNA confirmed that 68 of 73 Somalis (93.2%) and 261 of 282 non-Somalis (92.6%) with positive anti-HCV test results had active HCV infection. Of 30 Somali patients with HCC, 22 (73.3%) tested anti-HCV positive (odds ratio [OR], 31.3; 95% confidence interval [CI], 13.0-75.5; P<.001; compared with anti-HCV-negative Somalis), 5 (16.7%) were HBsAg positive (OR, 1.4; 95% CI, 0.5-3.7; P=.53), and 18 (60.0%) were HBcAb positive (OR, 1.8; 95% CI, 0.8-4.2; P=.16). Viral hepatitis was diagnosed coincident with HCC in 9 of 20 patients (45.0%) with HCV-associated HCCs. Only 4 of 24 cases of HCC (16.7%) were detected during surveillance., Conclusion: Both HBV and HCV occurred frequently in this sample of Somali immigrants. However, HCV was the major risk factor for HCC. Screening Somali immigrants for HCV infection may enhance the prevention, early detection, and optimal treatment of HCC., (Copyright © 2012 Mayo Foundation for Medical Education and Research.
