Viral hepatitis and Treponema pallidum prevalence in persons who underwent premarital blood tests in Argentina.

The objective of this study was to estimate the prevalence of different serological markers of hepatitis A, B and C viruses and Treponema pallidum among the adult population of Argentina. To achieve this, adults who attended health services for premarital exams (which are mandatory and includes screening for syphilis) were recruited. A cross-sectional study was designed with a cluster sampling strategy.

[Transient elastography: noninvasive assessment of liver fibrosis. Report of 1,000 cases in Argentina].

Background: Transient elastography (TE) is a noninvasive method for assessment of hepatic fibrosis.

Objective: To present the first case series evaluated in Latin America, in an University Hospital in Buenos Aires, during an 18-month period.

Methods: Data was collected between August 2009 and January 2011.

[Diagnosis, treatment and evolution of the Budd-Chiari syndrome: a single center experience].

Introduction: The Budd-Chiari syndrome is a low-prevalence disease due to an hepatic outflow obstruction. It is associated with procoagulant status and liver transplantation is one of the therapeutic tools for the treatment.

Objective: To evaluate the etiology, presenting form, treatment and evolution of patients with Budd-Chiari syndrome.

[Twenty-four weeks therapy with peginterferon alfa-2a could be similar to 48 weeks therapy in patients with HBeAg positive chronic hepatitis B and good predictors of response: results of a pilot study].

Background: 48 week therapy with peginterferon alfa-2a has demonstrated to be effective in about one third of patients with HBeAg-positive chronic hepatitis B. Although the recommended treatment duration for these patients is 48 weeks, there are no enough data supporting 48 weeks of therapy over 24 weeks of therapy. Treatment might be shortened particularly in patients with good predictors of response.
