Outcomes of hepatitis C virus seropositive donors to hepatitis C virus seronegative liver recipients: A large single center analysis.

INTRODUCTION AND OBJECTIVES: The success of direct-acting antivirals (DAA) has transformed the management of hepatitis C virus (HCV) infection and has led to the expansion of the deceased donor organ pool for liver transplantation. MATERIAL AND METHODS: We present a single center retrospective review of liver transplantations performed on HCV-seronegative recipients from HCV-seropositive organs from 11/2017 to 05/2020. HCV nucleic acid testing (NAT) was performed on HCV-seropositive donors to assess active HCV infection. RESULTS: 42 HCV-seronegative recipients underwent a liver transplant from a HCV-seropositive donor, including 21 NAT negative (20 liver, 1 simultaneous liver kidney transplant) and 21 NAT positive liver transplants. Two (9.5%) HCV antibody positive/NAT negative recipients developed HCV viremia and achieved sustained virologic response with DAA therapy. The remaining patients with available data (19 patients) remained polymerase chain reaction (PCR) negative at 6 months. 20 (95%) of HCV antibody positive/NAT positive recipients had a confirmed HCV viremia. 100% of patients with available data (15 patients) achieved SVR. Observed events include 1 mortality and graft loss and equivalent rates of post-transplant complications between NAT positive and NAT negative recipients. CONCLUSIONS: HCV-seropositive organs can be safely transplanted into HCV-seronegative patients with minimal complications post-transplant.

Cannabis use may reduce healthcare utilization and improve hospital outcomes in patients with cirrhosis.

INTRODUCTION AND OBJECTIVES: Previous studies reveal conflicting data on the effect of cannabis use in patients with cirrhosis. This research evaluates the impact of cannabis on hepatic decompensation, health care utilization, and mortality in patients with cirrhosis. MATERIAL AND METHODS: A retrospective analysis of the State Inpatient Database (SID) was performed evaluating patients from Colorado and Washington in 2011 to represent pre-cannabis legalization and 2015 to represent post-cannabis legalization. Multivariable analysis was performed to study the impact of cannabis on the rate of admissions with hepatic decompensations, healthcare utilization, and mortality in patients with cirrhosis. RESULTS: Cannabis use was detected in 370 (2.1%) of 17,520 cirrhotics admitted in 2011 and in 1162 (5.3%) of 21,917 cirrhotics in 2015 (p-value <0.001). On multivariable analysis, cirrhotics utilizing cannabis after its legalization experienced a decreased rate of admissions related to hepatorenal syndrome (Odds Ratio (OR): 0.51; 95% Confidence Interval (CI): 0.34-0.78) and ascites (OR: 0.73; 95% CI: 0.63-0.84). Cirrhotics with an etiology of disease other than alcohol and hepatitis C had a higher risk of admission for hepatic encephalopathy if they utilized cannabis [OR: 1.57; 95% CI: 1.16-2.13]. Decreased length of stay (-1.15 days; 95% CI: -1.62, -0.68), total charges (-$15,852; 95% CI: -$21,009, -$10,694), and inpatient mortality (OR: 0.68; 95% CI: 0.51-0.91) were also observed in cirrhotics utilizing cannabis after legalization compared to cirrhotics not utilizing cannabis or utilizing cannabis prior to legalization. CONCLUSION: Cannabis use in patients with cirrhosis resulted in mixed outcomes regarding hospital admissions with hepatic decompensation. A trend towards decreased hospital utilization and mortality was noted in cannabis users after legalization. These observations need to be confirmed with a longitudinal randomized study.

Insurance status impacts treatment for hepatocellular carcinoma.

INTRODUCTION AND AIM: Previous studies have identified treatment disparities in the treatment of hepatocellular carcinoma (HCC) based on insurance status and provider. Recent studies have shown more Americans have healthcare insurance; therefore we aim to determine if treatment disparities based on insurance providers continue to exist. MATERIALS AND METHODS: A retrospective database analysis using the NIS was performed between 2010 and 2013 including adult patients with a primary diagnosis of HCC determined by ICD-9 codes. Multivariable logistic regressions were performed to analyze differences in treatment, mortality, features of decompensation, and metastatic disease based on the patient's primary payer. RESULTS: This study included 62,368 patients. Medicare represented 44% of the total patients followed by private insurance (27%), Medicaid (19%), and other payers (10%). Patients with Medicare, Medicaid, and other payer were less likely to undergo liver transplantation [(OR 0.63, 95% CI 0.47-0.84), (OR 0.23, 95% CI 0.15-0.33), (OR 0.26, 95% CI 0.15-0.45)] and surgical resection [(OR 0.74, 95% CI 0.63-0.87), (OR 0.40, 95% CI 0.32-0.51), (OR 0.42, 95% CI 0.32-0.54)] than patients with private insurance. Medicaid patients were less likely to undergo ablation then patients with private insurance (OR 0.52, 95% CI 0.40-0.68). Patients with other forms of insurance were less likely to undergo transarterial chemoembolization (TACE) compared to private insurance (OR 0.64, 95% CI 0.43-0.96). CONCLUSION: Insurance status impacts treatment for HCC. Patients with private insurance are more likely to undergo curative therapies of liver transplantation and surgical resection compared to patients with government funded insurance.

A validated risk model for prediction of early readmission in patients with hepatic encephalopathy.

INTRODUCTION AND AIM: Hepatic encephalopathy (HE) is a common complication in cirrhotics and is associated with an increased healthcare burden. Our aim was to study independent predictors of 30-day readmission and develop a readmission risk model in patients with HE. Secondary aims included studying readmission rates, cost, and the impact of readmission on mortality. MATERIALS AND METHODS: We utilized the 2013 Nationwide Readmission Database (NRD) for hospitalized patients with HE. A risk assessment model based on index hospitalization variables for predicting 30-day readmission was developed using multivariate logistic regression and validated with the 2014 NRD. Patients were stratified into Low Risk and High Risk groups. Cox regression models were fit to identify predictors of calendar-year mortality. RESULTS: Of 24,473 cirrhosis patients hospitalized with HE, 32.4% were readmitted within 30 days. Predictors of readmission included presence of ascites (OR: 1.19; 95% CI: 1.06-1.33), receiving paracentesis (OR: 1.43; 95% CI: 1.26-1.62) and acute kidney injury (OR: 1.11; 95% CI: 1.00-1.22). Our validated model stratified patients into Low Risk and High Risk of 30-day readmissions (29% and 40%, respectively). The cost of the first readmission was higher than index admission in the 30-day readmission cohort ($14,198 vs. $10,386; p-value <0.001). Thirty-day readmission was the strongest predictor of calendar-year mortality (HR: 4.03; 95% CI: 3.49-4.65). CONCLUSIONS: Nearly one-third of patients with HE were readmitted within 30 days, and early readmission adversely impacted healthcare utilization and calendar-year mortality. With our proposed simple risk assessment model, patients at high risk for early readmissions can be identified to potentially avert poor outcomes.
