Hepatitis B virus infection in children
Date
2009
Abstract
Recent increases in Hepatitis B virus (HBV) infection prompted us to characterize HBV-infected children in Ireland and to audit management, by reviewing prospectively gathered data. Of 46 children (29 [63%] male), median age at presentation was 8.1 years (range 0.6â 17.6), monitoring duration was 22.5 months (range 1-101), 23/46 (50%) were European (including 9 [19.6%] Irish), 15 (32.6%) African and 9 (19.6%) Asian. Acquisition was vertical (25/46 [54.3%]), horizontal (5/46 [10.9%]), unknown (16/46 [34.8%]). HBV-DNA was >100,000,000 cpm in 20/32 (62.5%) with chronic infection. Hepatitis B e antigen (HBeAg) was detected in 32/44 (72.7%). We estimate that universal neonatal vaccination (UNV-HBV) could have prevented 22% of cases, and could limit further horizontal HBV spread. This supports the recent introduction of UNV-HBV.
