Background And Aims: Pirfenidone (PFD), an oral antifibrotic drug, has been authorized by the EMA and FDA for treatment of idiopathic pulmonary fibrosis. Few studies have addressed its use in advanced liver fibrosis (ALF). We evaluated a prolonged-release formulation (PR-PFD) plus standard of care on disease progression in ALF.

We investigated the incidence of clinical events among participants of the Evaluation of PegIntron in Control of Hepatitis C Cirrhosis (EPIC)3 program.
Methods: Data were analyzed from an open-label randomized study of patients with chronic hepatitis C who had failed to respond to interferon alfa plus ribavirin.
Background: Levofloxacin is a synthetic fluoroquinolone with a broad spectrum of antibacterial activity. It is indicated for the treatment of respiratory, sinus, skin, and urinary tract infections. Although generic formulations of oral levofloxacin are marketed in Mexico, a literature search did not identify published data concerning the bioavailability of these formulations; these data would be relevant to secure marketing of a test formulation in Mexico.

Ketorolac is used in the treatment of pain. There are various generic formulations of sublingual ketorolac available in Mexico.

There are several generic formulations of omeprazole available in Mexico; however, a literature search failed to identify published data concerning the bioavailability of these formulations in the Mexican population.
Objective: The aim of this study was to compare the bioavailability of 2 oral formulations of omeprazole 20-mg capsules, marketed for use in Mexico, in healthy volunteers: Inhibitron (test formulation) and LosecA 20 mg (reference formulation).
Despite steady progress in therapeutics of liver disease, portal systemic encephalopathy remains to be a great challenge for clinicians because of the heterogeneity of neuropsychiatric symptoms, multiple risk factors and complexity on achieving a sustained response. We aimed to evaluate the efficacy of L-Ornithin, L-Aspartate versus lactulose in Mexican patients with hyperammonemic hepatic encephalopathy. A total of 20 patients were randomly allocated to receive either lactulose(n = 10) or L-ornithine - L-aspartate (n = 10) for 2 weeks.

Increasing evidence has been reported of a close association of HCV infection with autoimmune and hematological processes, mainly cytopenias and lymphoproliferative disorders such as B cell non-Hodgkin's lymphoma. We describe the demographic, clinical and histopathological findings of nine patients from the Mexican population with non-Hodgkin's lymphoma and HCV infection.

Methods: Seven hundred clinical records of patients with HIV infection who entered the Instituto Nacional de Ciencias Médicas y de la Nutrición Salvador Zubirán from January 1987 to December 1996 were reviewed. All patients with alterations associated to hepatobiliary disease and/or liver function tests derangement throughout the clinical development of their disease were included.
Despite steady progress in antiviral treatment for patients with chronic hepatitis C virus(HCV), many patients still have detectable serum HCV RNA levels by the end of interferon-based treatment and are known as virological non-responders. Re-treatment of these patients not responding to previous therapy remains challenging. Studies of the dynamics of the HCV population show a marked decline in new cases since 1996; however, the relative proportion of non-responders is expected to increase over time and, similarly, the number of patients eligible for first-line treatment is expected to decrease.

The current criteria to confirm the absence of therapeutic response to HCV is based on the viral findings. Lack of response is defined as the failure to achieve a negative serological response to the virus in peripheral blood (serum or plasma) after 12 weeks of treatment with interferon alpha (2a or 2b), or 24 weeks of treatment with IFN and ribavirin. Up to 60% of patients treated with standard IFN alpha and ribavirin are considered non-responders.
