BACKGROUND We examined outcomes in recipients who underwent a liver transplant for HBV-induced liver disease and received a protocol for prophylaxis that did not use HBIG maintenance. RESULTS Between October 2002 and July 2005, a total of 14 liver transplant recipients were identified that met the study criteria. Mean recipient age was 47.6 yr; mean donor age was 37.2 yr. Category of transplant was as follows: cadaveric liver (n = 10, 71%), cadaveric split-liver (n = 2, 14%), and cadaveric liver-kidney (n = 2, 14%). Liver disease was diagnosed at a mean of 7.3 yr before transplant; three (21%) had a coexisting hepatocellular cancer at the time of transplant. Pre-transplant, all 14 (100%) recipients were hepatitis B surface antigen (HBsAg) positive, and 11 (79%) were HBV DNA positive (mean viral load of 251.2 pg/mL). Three (21%) were E antigen positive, and one (7%) was D antigen positive. Pre-transplant, seven patients (50%) were on anti-viral therapy and there was documented diminution in viral loads after initiating anti-viral therapy in 3 cases. Three (21%) were hepatitis C virus (HCV) antigen positive and all had low-RNA titers. With mean follow-up of 14.1 months, all 14 patients are alive with a functioning graft. Mean ALT, AST and total bilirubin values are currently at 43.2, 32.2, and 0.84, respectively. One recipient remains HBsAg surface antigen positive post-transplant but has normal lab values. The remaining recipients have no evidence of HBV recurrence by serology and protocol biopsies. The regimen has been well tolerated without the need for drug reduction or discontinuation because of side-effects. CONCLUSIONS Longer follow-up is needed, but this regimen may represent an alternative to chronic HBIG maintenance therapy.

D007136 Immunoglobulins Multi-subunit proteins which function in IMMUNITY. They are produced by B LYMPHOCYTES from the IMMUNOGLOBULIN GENES. They are comprised of two heavy (IMMUNOGLOBULIN HEAVY CHAINS) and two light chains (IMMUNOGLOBULIN LIGHT CHAINS) with additional ancillary polypeptide chains depending on their isoforms. The variety of isoforms include monomeric or polymeric forms, and transmembrane forms (B-CELL ANTIGEN RECEPTORS) or secreted forms (ANTIBODIES). They are divided by the amino acid sequence of their heavy chains into five classes (IMMUNOGLOBULIN A; IMMUNOGLOBULIN D; IMMUNOGLOBULIN E; IMMUNOGLOBULIN G; IMMUNOGLOBULIN M) and various subclasses.
