The hepatopulmonary syndrome (HPS), consisting of elevated alveolar-arterial oxygen gradient and intrapulmonary vascular abnormalities in the presence of advanced liver disease, is associated with high mortality. Liver transplantation (LT) has been used for the treatment of HPS; however, the success of LT for the treatment of HPS is not uniformly documented. We reviewed our experience over a 5-year period and identified eight adult patients with incapacitating respiratory symptoms compatible with HPS. ⋯ Currently, three patients are alive and off oxygen. The current report documents successful resolution of hypoxemia after LT in this pilot cohort. This supports the newly implemented United Network for Organ Sharing (UNOS) criteria, that LT for HPS may be extended to include patients with Pa(O2) < 60 mm Hg.

Severe donor organ shortage has provided the impetus for adult living donor liver transplantation (ALDLT). Despite rapid implementation and expansion of the procedure, outcome analysis of ALDLT is still incomplete. This study analyzed both donor and recipient outcomes after ALDLT at a single center. ⋯ Five grade 1 minor complications, by Clavien Classification, occurred in 4 of 20 (20%) donors. ALDLT using right lobe grafts is an effective procedure to expand a severely depleted donor, but is associated with a high complication rate despite good survival outcomes. Continuous standardized reporting of ALDLT outcomes is required to allow successful and safe implementation of the procedure.

De novo hepatitis B virus (HBV) infection after orthotopic liver transplantation (OLT) in patients negative for hepatitis B surface antigen (HBsAg) is between 1.7% and 3.5% in areas with a low prevalence of HBV infection. The importance of this problem and the efficacy of lamivudine treatment has not been defined in areas with a high prevalence of positivity to antibody to hepatitis B core antigen (Anti-HBc). To define the characteristics and the clinical impact of de novo HBV infection in OLT recipients and to evaluate the efficacy of lamivudine treatment in this context, 229 HBsAg (-) donors (145 men, 84 women) were retrospectively evaluated between June 1994 and June 2000. ⋯ Seven patients were treated with lamivudine for a mean period of 24.5 months; HBV-DNA became negative in 5 of 7 (71.4%), and HBeAg became undetectable in 3 of 6 patients (50%). Patient actuarial survival rates at 1, 3, and 5 years were 100%, 94.7%, and 81.2% for recipients of anti-HBc (+) livers and 95.2%, 83%, and 77.3% for recipients of anti-HBc (-) livers P = ns). In our area, the appearance of de novo HBV infection after OLT is related to grafting livers from anti-HBc (+) donors is associated with a benign outcome, with no liver failure or graft loss, and treatment with lamivudine is highly effective in the control of HBV replication.
