*Purpose: Introduction: While common in Asian countries, liver transplantation (LT) for patients with hepatitis B virus (HBV)/hepatitis D virus (HDV) co-infection is rare in the US; only 8 cases were reported in 2018. Post-transplant re-infection with HBV/HDV is commonly treated with hepatitis B immune globulin (HBIG) and antiviral drugs; however, data regarding dosage and frequency of HBIG therapy is limited. We report the outcome of HBV DNA-positive LT in a patient with chronic HBV/HDV co-infection.
*Methods: Case Presentation: A 34-year-old non-alcoholic Asian male with a history of liver cirrhosis secondary to chronic HBV/HDV co-infection underwent a successful LT from a CDC (Centers for Disease Control and Prevention) increased risk donor. Prior to LT, the recipient was HBsAg positive, HBcAb IgG+IgM positive, HBsAb negative, HCV Ab negative, and HCV RNA negative; was on Tenofovir Disoproxil Fumarate (TDF); and had undetectable HBV DNA but detectable HDV DNA. The donor was HBsAg negative, HbcAb IgG+IgM negative, and HBV DNA positive. The recipient was treated with HBIG 9,360 units IV daily for 7 days, with the first dose given intra-operatively and TDF was switched to Tenofovir Alafenamide (TAF). HBsAg and HBsAb titer were initially checked weekly and then monthly and HBIG 9,360 units IV were given if HBsAb was <500 m[IU]/mL. Twelve months post LT, the recipient continued to have negative HBsAg, undetectable HBV DNA, and undetectable HDV RNA (Table 1). Liver function tests remain normal.
*Results: Table 1: Hepatitis B and D serology pre and post liver transplantation
|Prior to LT||POD # 4||POD # 7||2 months post LT||12 months post LT|
|HBsAb titer(m[IU]/ml||>1000||>1000||566.2 m||766.5|
LT, liver transplant. POD, post operative day.
*Conclusions: Conclusions: Based on our single case experience and current lack of approved HDV antiviral treatment, high doses of HBIG are used to adequately suppress the HBsAg. This remains a key element in the management of HDV co-infection since long-term suppression of HBsAg is pivotal to prevent HDV recurrence. HBV antiviral treatment alone may not be adequate to achieve this goal.
