REVIEW

Chronic liver disease is accompanied by multiple hematological abnormalities. Iron deficiency anemia is a frequent complication of advanced liver disease. The etiology is multifactorial, mostly due to chronic hemorrhage into the gastrointestinal tract. The diagnosis of iron deficiency anemia is very challenging, as simple laboratory methods, including serum iron, ferritin, transferrin saturation (Tsat), and mean corpuscular volume are affected by the liver disease itself or the cause of the disease, resulting in difficulty in the interpretation of the results...

REVIEW
S A Townsend, P N Newsome
BACKGROUND: Non-alcoholic fatty liver disease is the fastest growing cause of liver disease in the Western world, yet there is no approved pharmacotherapy. While lifestyle modifications remain the mainstay of treatment, only a proportion of individuals are able to make or sustain them, and so more treatment options are required. AIM: To review the potential benefit of drugs used in clinical practice, those entering phase II trials, and compounds being investigated in pre-clinical studies...

Next to the kidneys and lungs, the liver has been recognized as an important regulator of acid-base homeostasis. While respiratory alkalosis is the most common acid-base disorder in chronic liver disease, various complex metabolic acid-base disorders may occur with liver dysfunction. Although the standard variables of acid-base equilibrium, such as pH and overall base excess, often fail to unmask the underlying cause of acid-base disorders, the physical-chemical acid-base model allows a more in-depth pathophysiological understanding and clinical judgement of acid-base disorders in patients with liver diseases...

OBJECTIVE: Acute upper gastrointestinal bleeding (UGIB) is a potentially life-threatening condition that requires rapid assessment in the emergency department (ED). We aimed to compare the performance of the AIMS65, Glasgow-Blatchford (Blatchford), preendoscopic Rockall (pre-Rockall), and preendoscopic Baylor bleeding (pre-Baylor) scores in predicting 30-day mortality in patients with acute UGIB in the ED setting. METHODS: Consecutive patients with acute UGIB who were admitted to the ED ward during 2012-2016 were retrospectively recruited...

Hepatic and kidney failure are often closely linked (Hepato-Renal Sindrome - HRS). Acute kidney injury (AKI) represents a well-known complication of liver or biliary tract disease. Pathophysiology of HRS is still not completely clear. At this stage we know the biological pathways of several kidney abnormalities in end stage liver disease patients. At the same time patient's prognosis is poor with bad outcomes despite the reversible nature of the kidneys' involvement. Liver transplantation represents the ultimate treatment for HRS patients...

Hepatorenal syndrome (HRS) is defined as the occurrence of renal dysfunction in a patient with end-stage liver cirrhosis in the absence of another identifiable cause of renal failure. The prognosis of HRS remains poor, with a median survival without liver transplantation of <6 months. However, understanding the pathogenesis of HRS has led to the introduction of treatments designed to increase renal perfusion and mean arterial blood pressure using vasopressors and albumin, which has led to improvement in renal function in ∼50% of patients...

REVIEW
Rahul Maheshwari, Ram M Subramanian
Acute pancreatitis results in nearly 250,000 admissions annually. Acute pancreatitis varies widely in its clinical presentation. Pancreatic necrosis accounts for substantial additional morbidity, with mortality rates remaining as high as 10% to 20% despite advances in critical care. The extent of necrosis correlates well with the incidence of infected necrosis, multiorgan failure, need for pancreatic debridement, and morbidity and mortality. Having established the diagnosis of pancreatic necrosis, goals of appropriately aggressive resuscitation should be established and adhered to in a multidisciplinary approach involving both medical and surgical critical care...

Hepatorenal syndrome (HRS) continues to be one of the major complications of decompensated cirrhosis, leading to death in the absence of liver transplantation. Challenges in precisely evaluating renal function in the patient with cirrhosis remain because of the limitations of serum creatinine (Cr) alone in estimating glomerular filtration rate (GFR); current GFR estimating models appear to underestimate renal function. Newer models incorporating renal biomarkers, such as the Cr-Cystatin C GFR Equation for Cirrhosis appear to estimate true GFR more accurately...

REVIEW
Michael F Vaezi, Yu-Xiao Yang, Colin W Howden
Safety issues associated with proton pump inhibitors (PPIs) have recently attracted widespread media and lay attention. Gastroenterologists are frequently asked about the appropriateness of PPI therapy for specific patients. Furthermore, some patients may have had PPI therapy discontinued abruptly or inappropriately due to safety concerns. Faced with such a wide variety of potentially serious adverse consequences, prescribers need to evaluate the evidence objectively to discern the likelihood that any reported association might actually be causal...

REVIEW
Farhad Sahebjam, John M Vierling
Autoimmune hepatitis is a chronic liver disease putatively caused by loss of tolerance to hepatocyte-specific autoantigens. It is characterized by female predilection, elevated aminotransferase levels, autoantibodies, increased γ-globulin or IgG levels and biopsy evidence of interface hepatitis. It is currently divided into types 1 and 2, based on expression of autoantibodies. Autoantigenic epitopes have been identified only for the less frequent type 2. Although autoimmune hepatitis occurs in childhood, this review focuses on disease in adults...

REVIEW
Nicholas J Talley
Functional dyspepsia (FD) is a common but under-recognized syndrome comprising bothersome recurrent postprandial fullness, early satiety, or epigastric pain/burning. Epidemiologically, there are two clinically distinct FD syndromes (although these often overlap clinically): postprandial distress syndrome (PDS; comprising early satiety or meal-related fullness) and epigastric pain syndrome. Symptoms of gastroesophageal reflux disease overlap with FD more than expected by chance; a subset has pathological acid reflux...

Dalbir S Sandhu, Ronnie Fass
Gastroesophageal reflux disease (GERD) characterized by heartburn and/or regurgitation symptoms is one of the most common gastrointestinal disorders managed by gastroenterologists and primary care physicians. There has been an increase in GERD prevalence, particularly in North America and East Asia. Over the past three decades proton pump inhibitors (PPIs) have been the mainstay of medical therapy for GERD. However, recently there has been an increasing awareness amongst physicians and patients regarding the side effects of the PPI class of drugs...

The term acute liver failure (ALF) is frequently applied as a generic expression to describe patients presenting with or developing an acute episode of liver dysfunction. In the context of hepatological practice, however, ALF refers to a highly specific and rare syndrome, characterised by an acute abnormality of liver blood tests in an individual without underlying chronic liver disease. The disease process is associated with development of a coagulopathy of liver aetiology, and clinically apparent altered level of consciousness due to hepatic encephalopathy...

REVIEW
Jussi M Kärkkäinen, Stefan Acosta
Acute mesenteric ischemia (AMI) is generally thought to be a rare disease, but in fact, it is more common cause of acute abdomen than appendicitis or ruptured abdominal aortic aneurysm in patients over 75 years of age. In occlusive AMI, surgical treatment without revascularization is associated with as high as 80% overall mortality. It has been shown that early diagnosis with contrast-enhanced computed tomography and revascularization can reduce the overall mortality in AMI by up to 50%. However, only a minority of patients with AMI are being treated actively with revascularization in the United States, and the situation is very likely similar in Europe as well...

REVIEW
Robert S Rahimi, Don C Rockey
Hepatic encephalopathy (HE) is a common complication of cirrhosis, leading to frequent hospitalizations. Because ammonia is thought to play an important role in the pathogenesis of HE, therapies specifically aimed at reducing ammonia levels have been developed for conditions causing hyperammonemia, including HE. Ammonia scavengers have been used in HE patients, leading to improvements in symptoms. Bowel cleansing with polyethylene glycol has also been studied recently, resulting in more rapid improvement in acute HE compared with lactulose...

REVIEW
Parth J Parekh, Luis A Balart
Hepatic encephalopathy (HE) is a commonly encountered sequela of chronic liver disease and cirrhosis with significant associated morbidity and mortality. Although ammonia is implicated in the pathogenesis of HE, the exact underlying mechanisms still remain poorly understood. Its role in the urea cycle, astrocyte swelling, and glutamine and gamma-amino-n-butyric acid systems suggests that the pathogenesis is multifaceted. Greater understanding in its underlying mechanism may offer more targeted therapeutic options in the future, and thus further research is necessary to fully understand the pathogenesis of HE...
