The challenges of integrating an immigrant population with chronic hepatitis B into long-term hepatology care: Lessons learned from a Bronx West African screening program.

OBJECTIVES

Hepatitis B virus (HBV) is endemic in West Africa. Because of immigration to the United States, screening and transition to long-term care is a significant public health concern. We describe the challenges of integrating individuals identified in a screening program into long-term care and the spectrum of disease severity.

METHODS

Between 2019 and 2023, 749 individuals were screened. Beginning 2022, all were offered a free serologic evaluation. Details of the previous diagnosis, HBV care, the serologic evaluation, aspartate aminotransferase to platelet ratio index, and Fibrosis index-4 scores were recorded. The results of transient elastography (TE) were correlated with the serologic evaluation.

RESULTS

A total of 75 (10%) individuals were hepatitis B surface antigen-positive, including 58 (77.3%) previously and 17 (22.7%) newly diagnosed. Despite attempts at linkage to care, only 14 (37.8%) of those diagnosed before the offer continued and/or entered long-term care. A total of 63 of 75 (84%) returned for the evaluation. Among 56 HBV treatment-naïve individuals, 66.1% had a serologic profile consistent with the carrier state. A total of 10 (18.2%) individuals met the criteria for HBV therapy, and 10 (21.7%) had ≥F2 fibrosis on TE. There was no correlation between aspartate aminotransferase to platelet ratio index and Fibrosis index-4 scores and TE. Eight (29.6%) of 27 patients with a profile of the HBV carrier state had ≥F2 fibrosis.

CONCLUSION

Integration of individuals with HBV from West Africa identified in a screening program into long-term care is challenging. Inclusion of a serologic evaluation in programs for immigrant communities should be considered. Up to 30% of individuals with a serologic profile consistent with the HBV carrier state may have ≥F2 fibrosis.
