Insights
Hepatitis B virus (HBV) testing and vaccination are suboptimal in hepatitis C virus (HCV) patients, despite high HBV prevalence. Improved strategies are needed for HBV screening, care linkage, and vaccination in this population.
Area of Science:
- Hepatology
- Infectious Diseases
- Public Health
Background:
- Hepatitis B virus (HBV) testing is crucial for co-infected patients with hepatitis C virus (HCV).
- Current HBV testing and vaccination rates in HCV-infected individuals are suboptimal.
- This study addresses the need for improved HBV management in HCV patients.
Purpose of the Study:
- To determine the prevalence of hepatitis B testing, care linkage, and vaccination in HCV patients.
- To identify gaps in HBV screening and management within a safety-net health system.
- To inform strategies for enhancing HBV care for HCV-infected individuals.
Main Methods:
- Retrospective cohort analysis of HCV-infected patients from 2004-2016.
- Utilized electronic health record data from Grady Health System.
- Assessed prevalence of HBV serological markers (HBsAg, anti-HBc, anti-HBs), HBV DNA/HBeAg testing, and HBV vaccination.
Main Results:
- 86% of HCV patients had HBsAg test results; 1.2% were HBsAg-positive.
- Among those with complete HBV serology, 27% were HBV-susceptible.
- Only 50% of HBV-susceptible patients received at least one dose of the HBV vaccine; linkage to care for HBsAg-positive patients was also limited.
Conclusions:
- A significant proportion of HCV patients have current or past HBV infection.
- Gaps exist in comprehensive HBV testing, care linkage, and vaccination for HCV patients.
- Enhanced strategies are required to improve HBV screening, care, and vaccination uptake in this population.
Background:
Hepatitis B virus (HBV) infection testing among persons with hepatitis C virus (HCV) infection is necessary to appropriately care for these patients, yet uptake of HBV testing and vaccination in this population is suboptimal.
Methods:
In a retrospective cohort analysis, we describe the prevalence of hepatitis B testing, linkage to hepatitis B care, and hepatitis B vaccination in patients with HCV infection within a large urban safety-net health system. Using a registry of HCV-infected patients with patient-level electronic health record data, that included demographic, clinical, and laboratory information from 2004 to 2016 from Grady Health System in Atlanta, GA, we describe (1) The prevalence of hepatitis B testing (hepatitis B surface antigen [HBsAg], core antibody [anti-HBc], surface antibody [anti-HBs]); (2) The proportion of HBsAg-positive persons receiving HBV DNA and e-antigen (HBeAg) as indicators for linkage to hepatitis B-directed care; and (3) The proportion of persons receiving hepatitis B vaccine.
Results:
Of 4224 HCV-infected patients, 3629 (86%) had test results for HBsAg and 43 (1.2%) were HBsAg-positive. Of 2342 (55%) with test results for all three HBV serological markers, median age was 60 years, 67% were male, and 83% were African-American, 789 (34%) anti-HBc positive only, 678 (29%) anti-HBc/anti-HBs positive, 190 (8.1%) anti-HBs positive only, and 642 (27%) were HBV-susceptible. Of HBsAg-positive patients, 21% received HBV DNA and 40% HBeAg testing. The proportion of HBV-susceptible patients receiving at least 1 dose of hepatitis B vaccine was 322/642 (50%).
Conclusions:
In a large cohort of HCV-infected patients, we found a high prevalence of current or past HBV infection, but there were gaps in complete hepatitis B testing, hepatitis B-directed care, and hepatitis B vaccination. Strategies are needed to increase hepatitis B testing, linkage to care, and administration of the hepatitis B vaccine for HCV-infected persons in this healthcare system.

Hepatic Portal System
At its core, the hepatic portal vein is the result of a confluence of the superior and inferior mesenteric veins along with the splenic vein. Each of these veins has a unique role. The superior mesenteric vein is...

Phosphodiester Linkages
Phosphodiester bond forms when a phosphoric acid molecule (H3PO4) links with two hydroxyl groups (–OH) of two other molecules, forming two ester bonds. Two water molecules are released in this process. The phosphodiester bond is commonly found in nucleic acids (DNA and RNA) and plays a critical role in their structure and function.
