Abstract C76: Community-wide outreach and screening to reduce hepatitis B, hepatitis C and liver cancer disparities among African immigrants in Minnesota

Background: In Minnesota, the 2012 Cancer Report by the Department of Health reported both the incidence of liver cancer and mortality rates due to liver cancer among Blacks were significantly higher than Caucasians. African immigration to Minnesota is the third highest by percentage of state population in the US. Given that viral hepatitis disproportionately affects sub-Saharan Africans and that these individuals are emigrating from countries where childhood HBV vaccination has only recently been implemented on a national scale, we speculate that this unique immigrant community may be a major contributor to the increased burden of viral hepatitis and liver cancer complications in the state. Limited research exists on the burden of viral hepatitis and hepatocellular carcinoma among African immigrants. Thus, we conducted a prospective community-wide screening to assess the rates of chronic HBV and HCV infections among Somali, Liberian and Kenyan immigrants in Minnesota. Methods: Several African community health centers and organizations in Minnesota were selected for the study. Individuals of Somali, Liberian or Kenyan descent were enrolled in a prospective screening study for chronic HBV and HCV infection. Blood samples were collected and tested for hepatitis B surface antigen (HBsAg), hepatitis B core antibody (HBcAb), hepatitis B surface antibody (HBsAb), and anti-hepatitis C virus antibody (anti-HCV). Follow-up testing, health education, counseling, and referral were provided to participants. Results: 853 participants provided blood specimens. 13.5% of participants had chronic HBV infection while 32.4% had prior HBV exposure with spontaneous viral clearance. 7% of participants had chronic HCV infection. Follow up and linkage to care were provided to participants with chronic hepatitis while preventive advice was provided to those who were negative for both infections. In particular, participants susceptible to HBV were informed about the availability of HBV vaccine in order to protect against future HBV infection. Conclusions: Chronic HBV and HCV are major health problems among recent African immigrants in Minnesota. Community-based screening is an effective way to identify and provide health education and linkage to care for individuals with or at risk for viral hepatitis. Citation Format: Essa A.
