Brain magnetic resonance (MR) study has shown metabolic abnormalities and changes in water distribution of the brain tissue that may relate to the pathogenesis of hepatic encephalopathy (HE). We designed a study to investigate the disturbances in brain water and metabolites during episodic HE using a 3-T MR scanner. Cirrhotic patients with different grades(More)
BACKGROUND & AIMS In spite of the high incidence of hepatic encephalopathy (HE) in cirrhosis, there are few observational studies. METHODS We performed an analysis to define the characteristics of HE and associated features using the database of the Canonic Study. Clinical, laboratory and survival data of 1348 consecutive cirrhotic patients admitted with(More)
BACKGROUND AND AIMS Transient elastography has been proposed as a tool to predict the risk of decompensation in patients with chronic liver disease. We aimed to identify risk groups of disease progression, using a combination of baseline liver stiffness measurement (LSM) and its change over time (delta-LSM) in patients with compensated advanced chronic(More)
Nephrotoxicity is one of the most common side effects of long-term immunosuppressive therapy with calcineurin inhibitors. We describe a case of distal renal tubular acidosis secondary to tacrolimus administration. A 43-year-old man with end-stage liver disease due to hepatitis C and B virus infections and alcoholic cirrhosis received a liver transplantation(More)
AIMS Confirm in patients with cirrhosis and gastrointestinal bleeding the safety of ornithine phenylacetate (OP) and assess the pharmacokinetic profile of OP and its effects on plasma ammonia. BACKGROUND OP is a drug that has shown experimentally to decrease hyperammonemia and improve hepatic encephalopathy. OP is safe in healthy subjects and in stable(More)
BACKGROUND & AIMS Antibiotic prophylaxis is a cornerstone in the management of acute variceal bleeding. However, emergence of multiresistant bacteria and antibiotic-associated complications is a growing problem in cirrhosis. It has been proposed that certain low-risk populations may have good outcomes without antibiotic. We aimed to analyse the stratified(More)
H epatic encephalopathy (HE) corresponds to a confusional syndrome that can progress to coma and is caused by liver failure and/or portal-systemic shunting. HE is frequent among hospitalized patients with cirrhosis; their admission into the hospital causes an important burden of care and carries important economic costs. In spite of major progress in the(More)
BACKGROUND We aimed to investigate the early changes in liver and spleen stiffness measurement (LSM, SSM) in hepatitis C virus (HCV) patients with compensated advanced chronic liver disease (cACLD) treated with new antivirals (DAA) to elucidate factors determining the initial change in stiffness and its implications for the long-term follow up of HCV-cured(More)
BACKGROUND Ornithine phenylacetate (OP) has been proven effective in lowering ammonia plasma levels in animals, and to be well tolerated in cirrhotic patients. A trial to assess OP efficacy in lowering plasma ammonia levels versus placebo in cirrhotic patients after an upper gastrointestinal bleeding was performed. The primary outcome was a decrease in(More)
