Background: It has been suggested that a relevant proportion of patients do not respond to nonselective beta-blockers (NSBB)s, which raises questions regarding the need for individualized therapy. The existence of potential heterogeneity in the treatment response can be assessed using the variability ratio (VR) of the outcome measurement (in this case, HVPG) between the treated and placebo groups. We conducted a systematic review and meta-analysis of randomized controlled trials to assess the potential heterogeneity in the portal pressure response to NSBBs.

Autoimmune liver disease (AILD) spans a spectrum of chronic disorders affecting the liver parenchyma and biliary system. Three main categories of AILD are autoimmune hepatitis (AIH), primary biliary cirrhosis (PBC), and primary sclerosing cholangitis (PSC). This review condenses the presentation and discussions of the Single Topic Conference (STC) on AILD that was held in Ottawa, Ontario, in November 2019.

Background And Aims: Malnutrition is a modifiable risk factor for morbidity and mortality in cirrhosis. Nutrition risk screening is recommended in cirrhosis nutrition guidelines, but is not routinely completed in practice. The patient-generated subjective global assessment short form (PG-SGA SF) is a patient-completed screen that has potential to be a substitute for more time and resource intensive nutrition screens.

Purpose Of Review: In 2015, as a consequence of the high development in noninvasive tests, Baveno VI consensus recommended for the first time the use of a prediction rule (liver stiffness <20kPa and platelet count > 150000) to identify patients at low risk of having varices and that could circumvent endoscopy. These became known as the Baveno VI criteria. We review here the data validating Baveno VI criteria and we discuss the attempts of expanding these criteria.

Article Synopsis
  • The study focused on evaluating the consistency and reliability of hepatic venous pressure gradient (HVPG) measurements in patients with cirrhosis, specifically for randomized controlled trials (RCTs) addressing portal hypertension (PH).
  • Analysis of 20 RCTs revealed that variability in HVPG measurements was lower in trials with only compensated cirrhosis patients, leading to smaller sample size requirements for these studies compared to those with decompensated cirrhosis.
  • Findings indicate that while HVPG measurement is reliable, the variability is greater in populations with more severe liver disease, which is crucial for planning clinical trials and using HVPG to direct treatment strategies.

Aim: An audit to review the outcome in the use of faecal calprotectin (FCP) to differentiate irritable bowel syndrome (IBS) from active inflammatory bowel disease (IBD) patients, and to detect active flares in known IBD patients in the local Hawkes Bay District Health Board (HBDHB) population from October 2013 to October 2014.

Method: Retrospective review of all FCP specimens requested in the HBDHB region from October 2013 to October 2014. Their indication, final diagnosis from clinical records, and endoscopic results are reviewed.

Background And Aim: The effect of type 2 diabetes mellitus (DM) on morbidity and mortality among hepatitis B virus (HBV) cirrhosis patients is poorly defined. We assess the effect of DM on the HBV cirrhosis outcomes and survival.

Methods: A retrospective study of HBV cirrhosis patients who sought care at a sole public hospital in a geographically defined region, from year 2000 to 2012.

Aim: This study reviews the presenting symptoms of colorectal cancer in the ethnically diverse Middlemore Hospital referral population of South Auckland, New Zealand. The performance of the newly introduced Auckland Regional Grading Criteria as prediction tool for selecting colorectal cancer cases referred from primary care was evaluated in this group.

Method: Retrospective review of all colorectal cancer (CRC) cases diagnosed between January 2006 and January 2011.
