Human noroviruses (HuNoVs) are a diverse group of RNA viruses that cause endemic and pandemic acute viral gastroenteritis. Previously, we reported that many HuNoV strains require bile or bile acid (BA) to infect human jejunal intestinal enteroid cultures. BA was not essential for the replication of a pandemic-causing GII.4 HuNoV strain. We found the hydrophobic BA glycochenodeoxycholic acid (GCDCA) promotes the replication of the BA-dependent strain GII.3 in jejunal enteroids. Furthermore, we found that inhibition of the G-protein-coupled BA receptor, sphingosine-1-phosphate receptor 2 (S1PR2), by JTE-013, reduced GII.3 infection dose-dependently and inhibited GII.3 cellular uptake in enteroids. Herein, we sought …

Despite continuous investigations in the diagnosis and treatment of severe acute pancreatitis (SAP), this disease still remains a critical condition with a mortality rate of up to 35%. The pathophysiology of SAP involves an important inflammatory reaction of the pancreas (mediated by inflammatory cytokines and immune system activation), causing severe local tissue damage as well as important systemic imbalances. IL-17 is an inflammatory mediator that have a pivotal role in SAP evolution, generating multiple interactions between inflammatory cytokines and significantly influencing the immune system response. Consequently, continuous renal replacement therapy/CRRT was added to the conventional therapy, leading to improved treatment …

BACKGROUND & AIMS: The available risk stratification indices for hepatocellular cancer (HCC) have limited applicability. We developed and externally validated an HCC risk stratification index in U.S. cohorts of patients with cirrhosis.

METHODS: We used data from 2 prospective U.S. cohorts to develop the risk index. Patients with cirrhosis were enrolled from 8 centers and followed until development of HCC, death, or December 31, 2021. We identified an optimal set of predictors with the highest discriminatory ability (C-index) for HCC. The predictors were refit using competing risk regression and its predictive performance was evaluated using the area under the receiver-operating …

Hepatitis A Virus And Hepatitis E Virus As Food- And Waterborne Pathogens—Transmission Routes And Methods For Detection In Food, Katalin Nemes, Sofia Persson, Magnus Simonsson

Faculty, Staff and Student Publications

Foodborne viruses are an important threat to food safety and public health. Globally, there are approximately 5 million cases of acute viral hepatitis due to hepatitis A virus (HAV) and hepatitis E virus (HEV) every year. HAV is responsible for numerous food-related viral outbreaks worldwide, while HEV is an emerging pathogen with a global health burden. The reported HEV cases in Europe have increased tenfold in the last 20 years due to its zoonotic transmission through the consumption of infected meat or meat products. HEV is considered the most common cause of acute viral hepatitis worldwide currently. This review focuses …

Actionable Solutions To Achieve Health Equity In Chronic Liver Disease, Patricia D Jones, Jennifer C Lai, Jasmohan S Bajaj, Fasiha Kanwal

Faculty, Staff and Students Publications

There are well-described racial and ethnic disparities in the burden of chronic liver diseases. Hispanic persons are at highest risk for developing nonalcoholic fatty liver disease, the fastest growing cause of liver disease. Hepatitis B disproportionately affects persons of Asian or African descent. The highest rates of hepatitis C occur in American Indian and Alaskan Native populations. In addition to disparities in disease burden, there are also marked racial and ethnic disparities in access to treatments, including liver transplantation. Disparities also exist by gender and geography, especially in alcohol-related liver disease. To achieve health equity, we must address the root …

BACKGROUND: Birt-Hogg-Dubé (BHD) syndrome, caused by germline alteration of folliculin (FLCN) gene, develops hybrid oncocytic/chromophobe tumour (HOCT) and chromophobe renal cell carcinoma (ChRCC), whereas sporadic ChRCC does not harbor FLCN alteration. To date, molecular characteristics of these similar histological types of tumours have been incompletely elucidated.

METHODS: To elucidate renal tumourigenesis of BHD-associated renal tumours and sporadic renal tumours, we conducted whole genome sequencing (WGS) and RNA-sequencing (RNA-seq) of sixteen BHD-associated renal tumours from nine unrelated BHD patients, twenty-one sporadic ChRCCs and seven sporadic oncocytomas. We then compared somatic mutation profiles with FLCN variants and RNA expression profiles between BHD-associated …

Primary Provider Beliefs And Practice Patterns Contribute To The Lack Of Hiv/Hcv Coinfected Patients Undergoing Liver Transplantation In The United States, Jonathan M. Fenkel, Md, Victor J. Navarro, Md

Division of Gastroenterology and Hepatology Faculty Papers

Conclusions:

1. The majority of primary providers were ambivalent toward or against LT for HIV/HCV coninfected patients.

2. Half of all respondents were unlikely to refer cirrhotic coinfected patients for LT evaluation.

3. HIV specialists were significantly more likely to believe transplant should be offered, but reported no difference in likelihood of LT referral.

4. These findings suggest that primary provider beliefs and self-reported practice patterns may partially explain the paucity of coinfected US liver transplant recipients.

Assessment Of Adherence To Guidelines For Hepatocellular Carcinoma Screening In Hiv/Hcv Coinfected Patients, Jonathan M. Fenkel, Md, Victor J. Navarro, Md

Division of Gastroenterology and Hepatology Faculty Papers

Conclusions:

1. Self-reported adherence with published guidelines for HCC screening is poor among primary providers for HIV/HCV coinfected patients, including HIV specialists and University-based providers.

2. Unnecessary imaging is also frequently ordered on non-cirrhotics, particularly by University-based providers.

3. Improved adherence to guidelines is needed among primary providers as over 50% of HCC's may be missed, and many patients many not be referred for subspecialty GI or Liver care, where screening practices may differ.
