Hepatitis E infection is an infrequent cause of acute hepatitis in the metropolitan area of Buenos Aires.

Unlabelled: Background Argentina is considered a region of low seroprevalence of hepatitis E virus (HEV), however; no studies have evaluated its burden among acute hepatitis cases.

Objectives: We aimed to estimate the proportion of acute HEV and outcome in a cohort of patients with acute hepatitis from 6 liver units in the Metropolitan area of Buenos Aires (MABA).

Study Design: We performed a prospective cohort study including patients ≥18 years with acute hepatitis (increase in transaminases x 5 ULN) fromJuly 2016 to May 2018.

Ribavirin treatment of a patient with chronic hepatitis E. First case reported in Latin America.

We describe a clinical case of a kidney transplant patient who presented a sudden elevation of his liver function tests. Once we ruled out the most frequent causes of acute hepatitis, serum tests for Hepatitis E were performed. Hepatitis E virus RNA was detected in blood and stools.

Ombitasvir/paritaprevir/ritonavir/dasabuvir ± ribavirin is safe and effective in HCV-infected patients in a real-life cohort from Latin America.

Information about the use of ombitasvir/paritaprevir/ritonavir/dasabuvir ± ribavirin (OBV/PTV/r/DSV ± RBV) in real-clinical practice in Latin America is scarce. We aimed to confirm safety and effectiveness of OBV/PTV/r/DSV ± RBV therapy in real-world setting. We analyzed a cohort of patients with genotype 1 infection treated with OBV/PTV/r/DSV ± RBV.

[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.

[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.

[Accuracy of multislice computed tomography in the diagnosis of hepatocellular carcinoma in patients with cirrhosis evaluated for liver transplantation].

Background: The presence of hepatocellular carcinoma (HCC) within Milan criteria provides additional points in the MELD (Model for end stage liver disease) system and benefits in the order of organ allocation. The imaging methods play a key role in this process and represent an essential tool in the diagnosis and staging of HCC.

Objectives: 1) To assess the accuracy of dynamic multidetector computed tomography (MDCT) in the diagnosis of HCC in patients with cirrhosis who are listed for liver transplantation.

Evaluation of calprotectin level in intestinal content as an early marker for graft rejection.

Introduction: The diagnosis of rejection after intestinal transplantation is still performed by endoscopic biopsy monitoring. Less invasive diagnostic procedures are desirable, although they are not available so far. Calprotectin, a stable cytosolic granulocyte protein, which previously was used as a marker of inflammatory processes, has been proposed to be a biochemical marker for rejection.

Isospora belli infection after isolated intestinal transplant.

Isospora belli is a protozoan that only affects humans, after ingestion of Isospora's oocysts. Immunocompetent patients usually do not develop the infection. Immunocompromised hosts may have profuse diarrhea with other gastrointestinal symptoms.
