Background: Immigrants are the largest subgroup living with chronic hepatitis B (HBV) infection in the United States. It is not well understood how immigration and associated social and cultural factors impact adherence to HBV monitoring.

Methods: We conducted a multicentre multilingual survey among foreign-born adults with chronic HBV between 7/2021 and 4/2023.

Article Synopsis
  • Non-cirrhotic portal hypertension (NCPH) includes liver diseases with portal hypertension but no cirrhosis, and the understanding of its progression and diagnosis is limited.
  • A study evaluated 50 patients, categorizing them based on the presence of specific portal hypertension features, and assessed their liver health over an average of 50 months.
  • Both patient groups had similar survival rates; however, lower platelet counts and higher liver stiffness measurements indicated poorer outcomes, highlighting the need for close monitoring of patients without specific PH features due to their risk for progression.

Background And Aims: The Fontan palliation is the final stage of surgery for many children born with univentricular physiology. Almost all Fontan patients develop liver fibrosis which may eventually lead to cirrhosis and hepatocellular carcinoma (HCC). These are important causes of morbidity and mortality in these patients.

Background: While there is higher prevalence of autoimmune, cholestatic and fatty liver disease in celiac disease (CeD), most data is from small-scale studies. We evaluated the prevalence and risk factors of the same using large cohort data.

Methods: A population-based cross-sectional study was conducted using Explorys, a multi-institutional database.

Article Synopsis
  • Systemic sclerosis (SSc) is an autoimmune disease that leads to progressive skin hardening and is categorized into two types: diffuse and limited cutaneous scleroderma.
  • Non-cirrhotic portal hypertension (NCPH) is characterized by high pressure in the portal vein without liver cirrhosis and can be linked to systemic diseases, particularly noting associations with nodular regenerative hyperplasia (NRH) and obliterative portal venopathy.
  • In this case study, a patient with limited cutaneous scleroderma presented with NCPH due to both NRH and obliterative portal venopathy, highlighting the need for thorough investigations in patients showing signs of portal hypertension.

Background: Non-alcoholic fatty liver disease (NAFLD) is a global health concern with a prevalence of about 25% amongst United States adults. Its increased prevalence is attributed to increase in patients with obesity and metabolic syndrome, partly due to similar mechanisms of injury. Nephrotic syndrome (NS) is a clinical entity resulting from extensive proteinuria leading to hypoalbuminemia, hyperlipidemia, edema, and other complications.

Hepatitis D viral infection in humans is a disease that requires the establishment of hepatitis B, relying on hepatitis B surface Ag and host cellular machinery to replicate and propagate the infection. Since its discovery in 1977, substantial progress has been made to better understand the hepatitis D viral life cycle, pathogenesis and modes of transmission along with expanding on clinical knowledge related to prevention, diagnosis, monitoring and treatment. The availability of serologic diagnostic assays for hepatitis D infection has evolved over time with current widespread availability, improved detection and standardized reporting.

Background: Non-alcoholic fatty liver disease (NAFLD) is currently considered as the most common cause of chronic liver disease worldwide. Risk factors for NAFLD have been well-described, including obesity, type 2 diabetes mellites (T2DM), dyslipidemia (DLP) and metabolic syndrome. Hypothyroidism has been identified as an independent risk factor for the development of NAFLD, although the literature is inconsistent.

Background: Existing literature on post-endoscopic retrograde cholangiopancreatography (ERCP) complications in patients with liver transplant remains scarce and largely inconsistent. We therefore aimed to systematically review and analyze the literature on complication rates associated with ERCP in patients with liver transplant.

Methods: We performed a comprehensive literature search in PubMed, PubMed Central, Embase, and ScienceDirect databases from inception through March 2020 to identify all the studies that evaluated post-ERCP complications in patients with liver transplant.

Background And Aims: Sweet syndrome [SS] is a dermatological condition associated with both inflammatory bowel disease [IBD] and azathioprine use. We performed a systematic review to better delineate clinical characteristics and outcomes of SS in IBD patients.

Methods: Peer-reviewed, full-text journal publications from inception to April 2020 in English language and adult subjects with IBD were included.

We discuss a case of a 20-year-old female who presented with history of fever, vomiting, and decreased oral intake for 10 days followed by one episode of generalized tonic-clonic seizure and altered sensorium for 5-6 h. On arrival in the emergency room, she had Glasgow Coma Scale 3 (E1V1M1), both pupils fixed and dilated, low blood pressure, low oxygen saturation, and few gasping breaths. She appeared to be brain dead and was assumed to have a very poor prognosis.

While opioid drug toxicity and side effects of long-term opioid use during medical care are well studied, there is little information regarding effects of ingestion of raw opium. Characterization of the effects to a particular alkaloid is difficult since raw opium contains a number of alkaloids. Here, we present a case of poisoning due to ingestion of raw opium leading to severe myocardial suppression.
