Preventive strategies for hypertension and its sequelae require an understanding of their predisposing conditions and recognition of at-risk individuals. Several factors, both genetic and nongenetic, are influential, and likely vary in their effects across ethnicities. This study aimed to identify dietary, lifestyle-related differences and genetic variants associated with hypertension in Filipinos.

Chronic pancreatitis tends to develop a number of complications that may constitute the form of presentation of the disease. Some societies have issued guidelines for diagnosis and treatment of chronic pancreatitis complications, but the level of evidence for any topic is usually low and recommendations tend to be weak. We aimed to provide defined position statements for the clinician based on updated review of published literature and on multidisciplinary expert agreement.

Chronic pancreatitis is associated with impaired quality of life, high incidence of comorbidities, serious complications and mortality. Healthcare costs are exorbitant. Some medical societies have developed guidelines for treatment based on scientific evidence, but the gathered level of evidence for any individual topic is usually low and, therefore, recommendations tend to be vague or weak.

Chronic pancreatitis is a chronic fibroinflammatory disease of the pancreas with prevalence around 50 cases per 100,000 inhabitants. It appears to originate from diverse and yet mixed etiological factors. It shows highly variable presenting features, complication types and disease progression rates.

Background And Aims: Endoscopic necrosectomy through lumen apposition metal stents (LAMS) is increasingly being used for complicated walled-off pancreatic necrosis (WOPN), but the need for necrosectomy after stent placement is not well understood. The aim of this study was to evaluate clinical, endoscopic, and radiologic predictors of the need for necrosectomy in patients treated with LAMS.

Methods: We retrospectively reviewed patients with WOPN treated with LAMS from 2014 to 2017.

Background/aims: Despite secondary-prophylaxis with β-blockers and endoscopic-variceal-ligation rebleeding is frequent, particularly within the first-6-weeks. Early-rebleeding may have greater impact on death-risk than late rebleeding, which may affect therapy. We assessed whether the influence of rebleeding on long-term survival of patients on secondary-prophylaxis is greater in patients with early-rebleeding.

Background & Aims: Whether the effect of β-blockers on arterial pressure and/or cardiac function may offset the benefit of reducing portal pressure in advanced cirrhosis is controversial. Herein, we aimed to evaluate the systemic and splanchnic hemodynamic effects of β-blockers in decompensated vs. compensated cirrhosis and to investigate the influence of systemic hemodynamic changes on survival times in decompensated cirrhosis.

Background & Aims: Guidelines recommend routine antibiotic prophylaxis for patients undergoing endoscopic ultrasonography-guided fine needle aspiration (EUS-FNA) of pancreatic cysts, but there is conflicting evidence for its necessity. We investigated whether performing the procedure without antimicrobial prophylaxis increases the incidence of infection.

Methods: We performed a multicenter, randomized, noninferiority trial to compare prophylaxis with ciprofloxacin vs placebo in patients with a pancreatic cyst requiring EUS-FNA at multiple centers in Spain.

Aim: To assess the relationship between the presence of toll-like receptor 4 (TLR4) polymorphisms and bacterial infections in cirrhotic patients with ascites.

Methods: We prospectively included consecutive patients with cirrhosis and ascites hospitalized during a 6-year period. Patients with human immunodeficiency virus (HIV) infection or any other immunodeficiency, patients with advanced hepatocellular carcinoma (beyond Milan's criteria) or any other condition determining poor short-term prognosis, and patients with a permanent urinary catheter were excluded.

Background And Study Aims: Precut sphincterotomy increases the success of deep biliary cannulation, but the method fails at the initial ERCP in 5-12% of cases. Although other invasive strategies are often used to access the bile duct, a second ERCP may be effective and safe. We evaluated the efficacy, safety, and factors related to a second ERCP after failed cannulation using a precut sphincterotomy.

Unlabelled: Monitoring the hemodynamic response of portal pressure (PP) to drug therapy accurately stratifies the risk of variceal rebleeding (VRB). We assessed whether guiding therapy with hepatic venous pressure gradient (HVPG) monitoring may improve survival by preventing VRB. Patients with cirrhosis with controlled variceal bleeding were randomized to an HVPG-guided therapy group (N = 84) or to a control group (N = 86).

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 placebo in cirrhotic patients after an upper gastrointestinal bleeding was performed. The primary outcome was a decrease in venous plasma ammonia at 24 hours.

Unlabelled: Acute-on-chronic liver failure (ACLF) is characterized by acute decompensation (AD) of cirrhosis, organ failure(s), and high 28-day mortality. We investigated whether assessments of patients at specific time points predicted their need for liver transplantation (LT) or the potential futility of their care. We assessed clinical courses of 388 patients who had ACLF at enrollment, from February through September 2011, or during early (28-day) follow-up of the prospective multicenter European Chronic Liver Failure (CLIF) ACLF in Cirrhosis study.

Background & Aims: Relative adrenal insufficiency (RAI) is common in critical illness and in cirrhosis, and is related with worse outcomes. The prevalence of RAI may be different in variceal and non-variceal bleeding and whether it may influence outcomes in these settings is unclear. This study assesses RAI and its prognostic implications in cirrhosis with variceal bleeding and in peptic ulcer bleeding.

Background: The hemoglobin threshold for transfusion of red cells in patients with acute gastrointestinal bleeding is controversial. We compared the efficacy and safety of a restrictive transfusion strategy with those of a liberal transfusion strategy.

Methods: We enrolled 921 patients with severe acute upper gastrointestinal bleeding and randomly assigned 461 of them to a restrictive strategy (transfusion when the hemoglobin level fell below 7 g per deciliter) and 460 to a liberal strategy (transfusion when the hemoglobin fell below 9 g per deciliter).

Background & Aims: Intravenous administration of albumin decreases the incidence of renal failure and mortality among patients with spontaneous bacterial peritonitis (SBP). However, it is unclear whether it should be given to all patients with SBP; we evaluated its efficacy.

Methods: We analyzed data from all episodes of SBP (n = 216) during a 7-year period that occurred in a nonselected series of 167 patients with cirrhosis.

Background: Endoscopic biliary stenting is a well-established palliative treatment in patients with unresectable malignant biliary strictures. Obstruction of uncovered self-expanding metal stent (SEMS) due to tumor ingrowth is the most frequent complication. Partially covered SEMS might increase stent patency but could favor complications related to stent covering, such as pancreatitis, cholecystitis, and migration.

Background: The influence of smoking on inflammatory bowel disease (IBD) susceptibility and on its clinical course is well known, but not its impact on drug efficacy. The aim of this study was to evaluate the response to thiopurines in patients with steroid-dependent IBD according to their smoking habits.

Methods: The medical records of 163 IBD patients (103 Crohn's disease [CD], 60 ulcerative colitis [UC]) in whom thiopurines were started because of steroid-dependency were reviewed.
