ReviewDrug-Induced Liver Injury due to Biologics and Immune Check Point Inhibitors.
Biological agents have in the last two decades become very important therapeutic agents, particularly for the treatment of various autoimmune disorders. The most widely used biologics are the tumor necrosis factor-α (TNF-α) receptor antagonists: infliximab, adalimumab, and etanercept. Other commonly used biological agents are interleukin (IL)-1 receptor antagonist (Anakinra), interleukin (IL)-6 receptor antagonist (tocilizumab), and CD20 surface antigen antagonist (rituximab). The current review will however focus on TNF-α receptor antagonists.

ReviewInpatient Hepatology Consultation: A Practical Approach for Clinicians.
Cirrhosis is the end-stage of chronic liver disease and constitutes a leading cause of potential years of working life lost, especially in the Americas and Europe. Its natural history is characterized by an asymptomatic phase called compensated cirrhosis, followed by a rapidly progressive phase characterized by liver-related complications termed decompensated cirrhosis. Complications could be related to portal hypertension and/or liver dysfunction, including ascites, portal hypertensive gastrointestinal bleeding, encephalopathy, and jaundice. This review will discuss some of the most important precipitants of hepatic decompensation, including acute variceal bleeding, spontaneous bacterial peritonitis, and hepatic encephalopathy.

ReviewNonalcoholic Fatty Liver Disease: A Unique Entity or Part of the Metabolic Syndrome or Both.
Nonalcoholic fatty liver disease (NAFLD) is a global public health problem. NAFLD is bidirectionally correlated with metabolic syndrome, which includes obesity, type 2 diabetes, hypertension, and dyslipidemia as major components. ⋯ Also, the presence of metabolic syndrome in patients with NAFLD has been linked to a higher risk of cardiovascular diseases, liver-related complications, extrahepatic malignancies, and mortality, and possibly vice versa. Multidisciplinary care pathways including lifestyle modifications, control of metabolic risk, and potentially beneficial treatments are important to improve the clinical outcomes of patients with NAFLD.

ReviewCirrhosis and Portal Hypertension: How Do We Deal with Ascites and Its Consequences.
Ascites is the most common complication of cirrhosis, with 5-year mortality reaching 30%. Complications of ascites (ie, spontaneous bacterial peritonitis, hepatorenal syndrome, recurrent/refractory ascites, and hepatic hydrothorax) further worsen survival. ⋯ The treatment of ascites is currently based on the management of fluid overload (eg, diuretics, sodium restriction, and/or paracenteses). In selected patients, long-term albumin use, norfloxacin prophylaxis, and transjugular intrahepatic portosystemic shunt reduce the risk of further decompensation and improve survival.
