Article Synopsis
  • Heart failure (HF) after transjugular intrahepatic portosystemic shunt (TIPS) affects up to 20% of cirrhotic patients, making it crucial to identify risk factors for better outcomes.
  • A retrospective study on 360 cirrhotic patients found that elevated right atrial pressure during TIPS and an increase in left atrial volume index within 180 days post-TIPS were linked to higher risks of HF and mortality, respectively.
  • The findings suggest that while cirrhotic cardiomyopathy status alone isn't predictive, monitoring echocardiographic changes could help identify patients at greater risk for complications after TIPS.

Background & Aims: Cirrhosis-related inpatient hospitalizations have increased dramatically over the past decade. We used a longitudinal dataset capturing a large metropolitan area in the United States from 2011 to 2021 to evaluate contemporary hospitalization rates and risk factors among frail patients with cirrhosis.

Methods: We conducted a retrospective, longitudinal cohort study using the Chicago Area Patient-Centered Outcomes Research Network (CAPriCORN) database, an electronic health record repository that aggregates de-duplicated data across 7 health care systems in the Chicago metropolitan area, from 2011 to 2021.

Article Synopsis
  • Sarcopenia, a condition characterized by loss of muscle mass, is prevalent in end-stage liver disease and can worsen patient outcomes during liver transplantation (LT).
  • This study assessed the practicality of using MRI to analyze body composition in LT patients, tracking changes both while on the waiting list and after transplantation.
  • Results indicated that a majority of participants had high muscle fat infiltration and low muscle volume at waitlisting, but after LT, there were increases in muscle volume and fat distribution, suggesting potential benefits from early intervention and monitoring.

Background And Aims: While transjugular intrahepatic portosystemic shunt (TIPS) is traditionally considered a bridge to liver transplant (LT), some patients achieve long-term transplant-free survival (TFS) with TIPS alone. Prognosis and need for LT should not only be assessed at time of procedure, but also re-evaluated in patients with favorable early outcomes.

Approach And Results: Adult TIPS recipients in the multicenter Advancing Liver Therapeutic Approaches retrospective cohort study were included (N=1,127 patients; 2,040 person-years follow-up).

The prevalence and mortality related to end-stage liver disease (ESLD) continue to rise globally. Liver transplant (LT) recipients continue to be older and have inherently more comorbidities. Among these, cardiac disease is one of the three main causes of morbidity and mortality after LT.

Interventions for portal hypertension are continuously evolving and expanding beyond the realm of medical management. When complications such as varices and ascites persist despite conservative interventions, procedures including transjugular intrahepatic portosystemic shunt creation, transvenous obliteration, portal vein recanalization, splenic artery embolization, surgical shunt creation, and devascularization are all potential interventions detailed in this article. Selection of the optimal procedure to address the underlying cause, treat symptoms, and, in some cases, bridge to liver transplantation depends on the specific etiology of portal hypertension and the patient's comorbidities.

Background: Metabolic dysfunction associated steatotic liver disease (MASLD) has been linked to heart failure with preserved ejection fraction (HFpEF). We sought to understand association between individuals with amounts of liver adiposity greater than would be predicted by their body mass index (BMI) in order to understand whether this disproportionate liver fat (DLF) represents a proxy of metabolic risk shared between liver and heart disease.

Methods: We studied 2,932 participants in the Multi-Ethnic Study of Atherosclerosis (MESA) who received computed tomography (CT) measurements of hepatic attenuation.

In a setting characterized by a growing prevalence of patients with alcohol-associated and metabolic dysfunction-associated steatotic liver diseases, coupled with an aging patient demographic, the incidence of cardiac comorbidities in liver transplant candidates is on the rise. These comorbidities not only pose barriers to transplant eligibility but also impact the intraoperative course and affect posttransplant outcomes. As such, there is a significant need to optimize the clinical management of these cardiac comorbidities.

Psychiatric disorders after liver transplantation (LT) are associated with worse patient and graft outcomes, which may be amplified by inadequate treatment. We aimed to characterize the burden of psychiatric disorders, treatment patterns, and associated financial burden among liver transplantation recipients (LTRs). IQVIA PharMetrics (R) Plus for Academics-a large health plan claims database representative of the commercially insured US population-was used to identify psychiatric diagnoses among adult LTRs and assess treatment.

Background: Non-alcoholic fatty liver disease (NAFLD) is recognized as a prevalent determinant of cardiometabolic diseases. The association between NAFLD and obesity warrants further research on how NAFLD modifies associations between body mass index (BMI) and Waist circumference (WC) with cardiometabolic risk (CMR).

Objective: This study assessed whether NAFLD modifies associations between BMI and WC with 5-year changes in CMR in 2366 CARDIA study participants.

Article Synopsis
  • Hepatorenal syndrome-acute kidney injury (HRS-AKI) is a serious complication of liver cirrhosis with a poor prognosis, and recent FDA approval of terlipressin offers new treatment options in the U.S.! -
  • Terlipressin has been used in Europe for years, leading to policy changes like the MELD score "lock," which prioritizes waitlist status for patients who respond to the drug; the article debates whether this should also apply in the U.S.! -
  • The discussion includes pros and cons of implementing the MELD lock for terlipressin responders, highlighting issues like equitable access, cost, and the need for coordinated research efforts among transplant community stakeholders to ensure effective

Liver transplantation is the curative therapy of choice for patients with early-stage HCC. Locoregional therapies are often employed as a bridge to reduce the risk of waitlist dropout; however, their association with posttransplant outcomes is unclear. We conducted a systematic review using Ovid MEDLINE and EMBASE to identify studies published between database inception and August 2, 2023, which reported posttransplant recurrence-free survival and overall survival among patients transplanted for HCC within Milan criteria, stratified by receipt of bridging therapy.

Social determinants of health (SDOH) are important predictors of poor clinical outcomes in chronic diseases, but their associations among the general cirrhosis population and liver transplantation (LT) are limited. We conducted a retrospective, multiinstitutional analysis of adult (≥18-years-old) patients with cirrhosis in metropolitan Chicago to determine the associations of poor neighborhood-level SDOH on decompensation complications, mortality, and LT waitlisting. Area deprivation index and covariates extracted from the American Census Survey were aspects of SDOH that were investigated.
