Tissue fibrosis is a core pathologic process that contributes to mortality in ~45% of the population and is likely to be influenced by the host genetic architecture. Here we demonstrate, using liver disease as a model, that a single-nucleotide polymorphism (rs12979860) in the intronic region of interferon-λ4 (IFNL4) is a strong predictor of fibrosis in an(More)
AIM To investigate the influence of metformin use on liver dysfunction and hepatic encephalopathy in a retrospective cohort of diabetic cirrhotic patients. To analyze the impact of metformin on glutaminase activity and ammonia production in vitro. METHODS Eighty-two cirrhotic patients with type 2 diabetes were included. Forty-one patients were classified(More)
INTRODUCTION Neurocysticercosis is the commonest cerebral parasitosis. The most recent cases reported in Spain have occurred in patients from endemic countries. The formation of giant subarachnoid cysts (GSC) is an uncommon complication of neurocysticercosis and its treatment is the subject of debate. We report two cases seen recently in the Valle del(More)
Hepatic encephalopathy is the main cognitive dysfunction in cirrhotic patients associated with impaired prognosis. Hyperammonemia plus inflammatory response do play a crucial role on hepatic encephalopathy. However, in some patients HE appeared without hyperammonemia and patients with increased levels of ammonia could not show cognitive dysfunction. This(More)
AIM Evaluate the association between phase angle and the development of hepatic encephalopathy in the long-term follow-up of cirrhotic patients. METHODS This was a prospective cohort study. Clinical, nutritional and biochemical evaluations were performed. Mann-Whitney's U and χ2 tests were used as appropriate. Kaplan-Meier curves and Cox proportional(More)
Hepatic encephalopathy (HE) is a neuropsychiatric syndrome which frequently accompanies acute or chronic liver disease. It is characterized by a variety of symptoms of different severity such as cognitive deficits and impaired motor functions. Currently, HE is seen as a consequence of a low grade cerebral oedema associated with the formation of cerebral(More)
There is a need, in NAFLD management, to develop non-invasive methods to detect steatohepatitis (NASH) and to predict advanced fibrosis stages. We evaluated a tool based on optical analysis of liver magnetic resonance images (MRI) as biomarkers for NASH and fibrosis detection by investigating patients with biopsy-proven NAFLD who underwent magnetic(More)
BACKGROUND Virological response to peginterferon + ribavirin (P+R) at week 4 can predict sustained virological response (SVR). While patients with rapid virological response (RVR) do not require triple therapy, patients with a decline <1 log10 IU/ml HCVRNA (D1L) should have treatment discontinued due to low SVR rate. AIM To develop a tool to predict first(More)
