Clinical questions

•Who is getting acute HBV in the U.S.?•What is severe acute HBV?•How and when should we treat severe

acute HBV?

Acute HBV demographics

•Acute HBV incidence has declined 82% since 1990

•8.5 cases per 100,000 in 1990•1.5 cases per 100,000 in 2007 (the lowest

rate ever recorded)•Declines in all age groups, but especially

in children <15 yrs, attributable to vaccination (national vaccination strategy implemented in 1991)

Daniels et al. MMWR Surveill Summ. 2009 May 22;58(3):1-27.

Acute HBV demographics

•In 2007, 4,519 acute symptomatic cases reported (43,000 additional new infections, asymptomatic)

•Risk factors for infection: 38% multiple sex partners, 11% MSM, 6% sexual contact with a person known to have hepatitis B. IVDU reported for 15% of persons.

•2007 reports: 76% had jaundice, 40% were hospitalized, and 2% died.Daniels et al. MMWR Surveill

Summ. 2009 May 22;58(3):1-27.

Management of severe acute HBV

Typical acute HBV clearance

Tillman et al. Liver Int. 2012 Apr;32(4):544-53.

Acute hepatitis B

•In approximately 1% of cases, acute HBV progresses to liver failure with need for transplantation

Treatment with lamivudine for severe acute HBV•Large series of 37 patients (multicenter)•Definition of severe acute hepatitis:

▫Bilirubin >=10 mg/dl▫INR > 1.6▫Presence of hepatic encephalopathy

•Transplant-free survival with lamivudine for severe/acute to fulminant hepatitis B was 78.3% (29 of 37 patients) compared with 21.6% of historic controls (p < 0.001). Tillman HL et al. J Viral Hepat

2006; 13:256-63.

Treatment with newer antivirals for acute HBV•Prospective study, 6 patients in Germany

with HBV-related acute liver failure•Entecavir 1 mg/day within 1-18 days of

admission, continued for at least 3 months

•Normalization of INR, ALT, and bilirubin within 3 months

•1 patient went on to develop chronic hepatitis B

Jochum C et al. Digestion 2009; 80:235-40.

Risk of increasing chronicity with treating acute HBV•57 patients hospitalized with acute HBV

acquired in adulthood in Japan•7 of 57 patients developed persistence

(HBsAg positive 6 months after index hospitalization)

•6 of the 7 received prednisolone or glycyrrhizin during acute illness, 1 did not

•Infection persisted in 86% of patients who received treatment vs. 2% of patients who did not (p = 0.01) Kobayashi M et al. J Med Virol

2002; 68:522-8.

Take home points

•Fortunately, frequency of severe acute to fulminant liver failure in acute HBV is low

•For acute severe to fulminant HBV-related liver failure, lamivudine has shown benefits in transplant-free survival

•Small case series promising for entecavir in the setting of acute severe to fulminant HBV-related liver failure
