AbstractBackground and aims: The latest clinical practice guideline from European Association for the Study of the Liver (EASL) published in 2017 advocate the use of entecavir or tenofovir alafenamide (TAF) over tenofovir disoproxil fumarate (TDF) according to age, bone disease and renal alteration. As patients with chronic hepatitis B (CHB) are aging with improved survival under better healthcare, more patients may fulfil these criteria. We aimed to determine the prevalence of these criteria in the territory-wide CHB cohort in Hong Kong over 18 years from year 2000 to 2017.

Method: CHB patients who have been under the care at primary, secondary and tertiary medical centers in the public sector in Hong Kong were identified through the Clinical Data Analysis and Reporting System of the Hospital Authority. The demographics and prevalence of relevant bone and renal co-morbidities, and relevant laboratory parameters were determined according to patients’ first appearance in four time periods: 2000-2004, 2005-2009, 2010-2013 and 2014-2017.

Results: 136, 414 CHB patients were included. The prevalence of the above criteria increased over the four periods: age >60 years 11.6%, 20.4%, 27.6% and 35.4%; Steroid/medications that worsen bone density 57.2%, 50.5%, 56.0% and 61.8% respectively; albuminuria 0.2% 0.4% 0.7% and 1.1% respectively, and low phosphate (<2.5 mg/dl) 3.9%, 4.0%, 5.1% and 7.0% respectively (all P < 0.001; Figure).

Conclusion: CHB patients are getting older with increasing prevalence of indications to choose entecavir or TAF over TDF according to the latest EASL guidelines.
