Hepatitis E: un virus infrecuente o un agente infrecuentemente pensado? / [Hepatitis E: an infrequent virus or an unfrecuently investigated agent?].

Two cases of hepatitis E that were assisted in our Unit of Hepatology and Liver Transplantation are described in this article. The first patient had prior hepatic involvement and therefore a more severe course, whereas the second case, with normal liver function, only developed a self-limited acute hepatitis.

Hepatocarcinoma dentro y fuera de los criterios de Milán: resultados de un centro de trasplante hepático en la Argentina / [Hepatocellular carcinoma within Milan criteria and beyond: outcomes of liver transplantation in a single Argentinian institution].

Hepatocellular carcinoma (HCC) recurrence following liver transplantation is associated to bad prognosis. We retrospectively analyzed the data of 95 patients who underwent liver transplantation for HCC. Recurrence rate and variables associated with recurrence were reviewed. According to the findings on the explanted livers they were divided in two groups: Milan (M) 67

. Global recurrence rate, and M-group and NM-group recurrence rates were 19

, respectively (P = 0.001). Although in the univariate analysis we found some factors associated to recurrence (hemocromathosis, year of transplant, bilobar distribution, vascular invasion and previous chemoembolization), they were not independent predictors of recurrence in the multivariate analysis. Actuarial survival in cirrhotic patients with and without HCC at 1, 3 and 5 years was 86

(NS), and 67

(P = 0.002), respectively; whereas actuarial survival of the M and NM groups was 86

, and 78

, respectively (P = 0.02). We had a satisfactory five-year global survival in our series even though one third of our patients grafted for HCC were outside Milan criteria.
