Abstract

Aim: To describe the characteristics of patients with chronic hepatitis B (CHB) presenting to a tertiary paediatric hospital in Perth, Western Australia. Review of implementation of previous follow-up recommendations for the cohort was also undertaken.

Method: A retrospective data analysis of all individuals aged between 0 and 17 years presenting to the tertiary children's hospital who were hepatitis B surface antigen (HBsAg) positive over 8 years (2013-2020). Demographic features, clinical progress and follow up are described, including proportion transferred to adult services.

Results: Seventy-four patients were identified to have CHB; mean age at diagnosis 11 years; standard deviation 4 years; 41 (55%) male. Cultural and ethnolinguistic diversity was high; 74% (n = 55) were from refugee-like backgrounds. Many did not demonstrate English proficiency (23/40; 75%) and 7 (10%) Australian born including 4 patients who were Aboriginal. Most patients (58%) with CHB were in the hepatitis B e antigen-positive chronic infection phase with no intervention provided. Seventeen children had undergone liver ultrasonography and one underwent liver biopsy; none received antiviral treatment. Follow up was concerning; 28 (38%) had at least one clinic non-attendance, 24 (32%) lost to follow-up and interpreter utilisation was poorly documented. Thirty-nine (53%) were transferred to adult services with only 56% attending follow-up.

Conclusion: CHB burden is higher in those from culturally and ethnolinguistically diverse backgrounds. There is a significant loss to follow-up and suboptimal transfer to adult services. Improved recall, education and referral processes are necessary to overcome language, socioeconomic and cultural barriers. Although childhood complications are infrequent, longitudinal monitoring is crucial to prevent long-term complications and adult morbidity.
