Hepatitis B transmission/reactivation associated with Hepatitis B core antibody and Hepatitis C nucleic acid testing positive organs: A report from the Organ Procurement and Transplantation Network Disease Transmission Advisory Committee.

Background: Better access to direct-acting antiviral (DAA) therapy has broadened the utilization of hepatitis C virus (HCV) nucleic acid testing (NAT) positive organs with excellent outcomes. However, DAA therapy has been associated with hepatitis B virus (HBV) reactivation.

Aim: To determine the risk of HBV transmission or reactivation with utilization of HBV core antibody positive (HBcAb+) and HCV NAT positive (HCV+) organs, which presumably required DAA therapy.

Considerations in gender-affirming hormone therapy in transgender and gender diverse patients undergoing liver transplantation.

Liver transplantation is lifesaving for patients with end-stage liver disease. Similar to the role of transplantation for patients with end-stage liver disease, gender-affirming hormone therapy (GAHT) can be lifesaving for transgender and gender diverse (TGGD) patients who experience gender dysphoria. However, management of such hormone therapy during the perioperative period is unknown and without clear guidelines.

Bifidobacteria metabolize lactulose to optimize gut metabolites and prevent systemic infection in patients with liver disease.

Progression of chronic liver disease is precipitated by hepatocyte loss, inflammation and fibrosis. This process results in the loss of critical hepatic functions, increasing morbidity and the risk of infection. Medical interventions that treat complications of hepatic failure, including antibiotic administration for systemic infections and lactulose treatment for hepatic encephalopathy, can impact gut microbiome composition and metabolite production.

Transplant of organs from donors with positive SARS-CoV-2 nucleic acid testing: A report from the organ procurement and transplantation network ad hoc disease transmission advisory committee.

Background: Decisions to transplant organs from severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) nucleic acid test-positive (NAT+) donors must balance risk of donor-derived transmission events (DDTE) with the scarcity of available organs.

Methods: Organ Procurement and Transplantation Network (OPTN) data were used to compare organ utilization and recipient outcomes between SARS-CoV-2 NAT+ and NAT- donors. NAT+ was defined by either a positive upper or lower respiratory tract (LRT) sample within 21 days of procurement.

Consensus recommendations for use of maintenance immunosuppression in solid organ transplantation: Endorsed by the American College of Clinical Pharmacy, American Society of Transplantation, and the International Society for Heart and Lung Transplantation.

Advances in maintenance immunosuppression over the past three decades have improved solid organ transplantation outcomes dramatically. Uninterrupted access to immunosuppression is paramount to minimize rejection and maintain allograft and patient survival. There is no standardized approach to maintenance immunosuppression management.

Consensus recommendations for use of maintenance immunosuppression in solid organ transplantation: Endorsed by the American College of Clinical Pharmacy, American Society of Transplantation, and International Society for Heart and Lung Transplantation: An executive summary.

Advances in maintenance immunosuppression over the past three decades have improved solid organ transplantation outcomes dramatically. Uninterrupted access to immunosuppression is paramount to minimize rejection and maintain allograft and patient survival. Agents used vary based on transplanted organ, center-specific protocol, provider expertise, insurance formularies, ability to cover co-pays, recipient characteristics and tolerability.

Mandatory Hepatology Education for Internal Medicine Residents: Long-Term Effects and Implications for Workforce Needs.

We previously created a mandatory, inpatient, hepatology resident curriculum that immediately improved comfort, knowledge, and career interest in chronic liver disease (CLD). The durability of these effects needs to be known to use this intervention to address the hepatologist shortage. Thus, we aimed to assess this curriculum's long-term outcomes on internal medicine (IM) residents' CLD comfort, knowledge, and career interest.

National Early Career Transplant Hepatologist Survey: Compensation, Burnout, and Job Satisfaction.

Despite the growth of transplant hepatology as a subspecialty over the past decade, data on professional roles and compensation models remain lacking. Furthermore, the prevalence of physician burnout and job satisfaction are unknown in this profession. We aimed to conduct a comprehensive assessment of early career transplant hepatologists to fill these voids in knowledge and to inform current and future transplant hepatologists.

Incidence, Clinical Correlates, and Outcomes of Pulmonary Hypertension After Kidney Transplantation: Analysis of Linked US Registry and Medicare Billing Claims.

Background: The incidence, risks, and outcomes associated with pulmonary hypertension (P-HTN) in the kidney transplant (KTx) population are not well described.

Methods: We linked US transplant registry data with Medicare claims (2006-2016) to investigate P-HTN diagnoses among Medicare-insured KTx recipients (N = 35 512) using billing claims. Cox regression was applied to identify independent correlates and outcomes of P-HTN (adjusted hazard ratio [aHR] 95%LCLaHR95%UCL) and to examine P-HTN diagnoses as time-dependent mortality predictors.

A National Survey of Hepatocellular Carcinoma Surveillance Practices Following Liver Transplantation.

Unlabelled: Recurrence of hepatocellular carcinoma (HCC) is an important predictor of survival after liver transplantation (LT). Recent studies show that early diagnosis, aggressive treatment, and surveillance may improve outcomes after HCC recurrence. We sought to determine the current practices and policies regarding surveillance for HCC recurrence after LT.

Barriers to ideal outcomes after pediatric liver transplantation.

Long-term survival for children who undergo LT is now the rule rather than the exception. However, a focus on the outcome of patient or graft survival rates alone provides an incomplete and limited view of life for patients who undergo LT as an infant, child, or teen. The paradigm has now appropriately shifted to opportunities focused on our overarching goals of "surviving and thriving" with long-term allograft health, freedom of complications from long-term immunosuppression, self-reported well-being, and global functional health.

Opioid and opioid substitution therapy in liver transplant candidates: A survey of center policies and practices.

This national survey sought to determine the practices and policies pertaining to opioid and opioid substitution therapy (OST) use in the selection of liver transplant (LT) candidates. Of 114 centers, 61 (53.5%) responded to the survey, representing 49.

Liver Transplantation in the Obese Cirrhotic Patient.

Despite the rapidly increasing prevalence of obesity in the transplant population, the optimal management of obese liver transplant candidates remains undefined. Setting strict body mass index cutoffs for transplant candidacy remains controversial, with limited data to guide this practice. Body mass index is an imperfect measure of surgical risk in this population, partly due to volume overload and variable visceral adiposity.

Accepting Hearts From Hepatitis C-Positive Donor: Can We Expand the Donor Pool?

Background: Until recently, transplantation from hepatitis C-positive donors was relatively contraindicated as eradication of active hepatitis C previously required an interferon-based regimen that has been associated with rejection in solid organ transplantation. New interferon-free treatment regimens for hepatitis C have fewer adverse events and higher cure rates than interferon-based regimens. Interferon-free regimens have been shown to be safe in the liver transplantation literature, but little is known about the safety and efficacy of treatment in heart transplantation.

A case of Q fever after liver transplantation.

Coxiella burnetii, the causative agent of Q fever, is a zoonosis that causes both acute and chronic disease in humans. Few cases have been reported in solid organ transplant recipients, and this case highlights the need to include Q fever in the differential diagnosis for fever of unknown origin in solid organ transplant hosts.

Biopsy Specimens From Allograft Liver Contain Histologic Features of Hepatitis C Virus Infection After Virus Eradication.

Background & Aims: Most patients, even those who have received a liver transplant, achieve a sustained virologic response (SVR) to therapy for hepatitis C virus (HCV) infection. Little is known about the histologic features of liver biopsy specimens collected after SVR, particularly in patients who have received a liver transplant. We aimed to better characterize the histologic features of allograft liver biopsy specimens from patients who achieved SVR to anti-HCV therapy after liver transplantation.

Prevalence of non-alcoholic fatty liver disease and risk factors for advanced fibrosis and mortality in the United States.

In the United States, non-alcoholic fatty liver disease (NAFLD) is the most common liver disease and associated with higher mortality according to data from earlier National Health and Nutrition Examination Survey (NHANES) 1988-1994. Our goal was to determine the NAFLD prevalence in the recent 1999-2012 NHANES, risk factors for advanced fibrosis (stage 3-4) and mortality. NAFLD was defined as having a United States Fatty Liver Index (USFLI) > 30 in the absence of heavy alcohol use and other known liver diseases.

Sofosbuvir plus ledispasvir for recurrent hepatitis C in liver transplant recipients.

Hepatitis C virus (HCV) recurrence after liver transplantation (LT) is associated with worse outcomes. The combination of ledipasvir (LDV) and sofosbuvir (SOF) has been approved for HCV treatment after LT, but there are limited data on the effectiveness and safety of LDV/SOF in the "real-world" setting. This multicenter study is the largest report to date on the effectiveness and safety of LDV/SOF in the post-LT setting.

Rifaximin Decreases the Incidence and Severity of Acute Kidney Injury and Hepatorenal Syndrome in Cirrhosis.

Background: While the effects of rifaximin have been shown to be protective against acute kidney injury (AKI) and hepatorenal syndrome (HRS) in alcohol-induced cirrhosis, its long-term effects on the renal function of other cirrhotic patients are unknown.

Aim: To examine the long-term effects of rifaximin on the renal function of patients with cirrhosis from various etiologies.

Methods: In a retrospective study, we examined cirrhotic patients at the University of Chicago Liver Clinic from January 1, 2011, to December 31, 2014.
