Active coping, resilience, post-traumatic growth, and psychiatric symptoms among early and late liver transplant survivors.

Understanding survivorship experiences at different stages postliver transplantation (poat-LT) is essential to improving care. Patient-reported concepts including coping, resilience, post-traumatic growth (PTG), and anxiety/depression, have been implicated as important predictors of quality of life and health behaviors after LT. We aimed to descriptively characterize these concepts at different post-LT survivorship stages. This cross-sectional study featured self-reported surveys measuring sociodemographic, clinical characteristics, and patient-reported concepts including coping, resilience, PTG, anxiety, and depression. Survivorship periods were categorized as early (1 y or below), mid (1-5 y), late (5-10 y), and advanced (10 y or above). Univariable and multivariable logistic and linear regression modeling examined factors associated with patient-reported concepts. Among 191 adult LT survivors, the median survivorship stage was 7.7 years (interquartile range: 3.1-14.4) and median age was 63 years (range: 28-83); most were male (64.2%) and Caucasian (84.0%). High PTG was more prevalent in the early survivorship period (85.0%) than late survivorship (15.2%). High trait resilience was only reported by 33% of survivors and associated with higher income. Lower resilience was seen among patients with longer LT hospitalization stays and late survivorship stages. About 25% of survivors had clinically significant anxiety and depression, which was more frequent among early survivors and females with pre-LT mental health disorders. In multivariable analysis, factors associated with lower active coping included survivors ≥65 years, non-Caucasian race, lower levels of education, and nonviral liver disease. In a heterogeneous cohort including early and late LT survivors, there was variation in levels of PTG, resilience, anxiety, and depression at different survivorship stages. Factors associated with positive psychological traits were identified. Understanding determinants of LT survivorship has important implications for how we should monitor and support LT survivors.

Alcohol-Associated Liver Disease Mortality Increased From 2017 to 2020 and Accelerated During the COVID-19 Pandemic.

Alcohol consumption has risen substantially in the United States in the past 2 decades.1,2 Alcohol-associated liver disease (ALD) represents a greater inpatient financial burden than all other etiologies of cirrhosis combined3 and is now the leading indication for liver transplantation.4 A recent study reported that ALD mortality increased between 2006 and 2017.5 Since 2017, alcohol consumption has continued to rise, and more significantly during the COVID-19 pandemic.2 The aim of this research letter is to provide the most updated trends in ALD-related mortality in the United States and to quantify the rate of change of ALD-related mortality over time.

Antiplatelet Medications Are Associated With Bleeding and Decompensation Events Among Patients With Cirrhosis.

BACKGROUND: In an aging population with cardiovascular comorbidities, anticoagulant (AC), antiplatelet (AP), and nonsteroidal anti-inflammatory drug (NSAID) use are increasing. It remains unclear whether these agents pose increased bleeding risk in cirrhosis. This study aimed to assess the association between these medications and bleeding and portal hypertension complications in cirrhosis. METHODS: The IMS PharMetrics database was used to identify privately insured adults diagnosed with cirrhosis from 2007 to 2015, stratified as compensated or decompensated based on the presence of portal hypertensive complications 1 year before cirrhosis diagnosis. Bleeding or decompensation outcomes were assessed 6 to 18 months after cirrhosis diagnosis using a landmark analysis design. Multivariable Cox proportional hazards regression modeling assessed associations between AC, AP, and NSAID drug exposures and outcomes adjusting for covariates. RESULTS: A total of 18,070 cirrhosis patients were analyzed; 57% male; 74% ages 50 to 64 years; 34% with a prior decompensation. Overall, 377 (2%) had claims for ACs; 385 (2%) APs; and 1231 (7%) NSAIDs. APs were associated with increased bleeding [adjusted hazard ratio (aHR)=1.31; 95% confidence interval (CI): 1.00, 1.72] and decompensation events (aHR=1.44; 95% CI: 1.06, 1.95) in a 9-month landmark analysis. NSAIDs were significantly associated with bleeding events (aHR=1.29; 95% CI: 1.06, 1.57) on 3-month landmark analysis. No statistically significant associations were seen between ACs and bleeding or decompensation outcomes in adjusted analyses. CONCLUSIONS: AP use was associated with increased bleeding and decompensation events among privately insured patients with cirrhosis. NSAID use was associated with significant early bleeding, but not decompensations. Lastly ACs were not associated with bleeding or decompensation outcomes.

COVID-19 and liver disease: mechanistic and clinical perspectives.

Our understanding of the hepatic consequences of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection and its resultant coronavirus disease 2019 (COVID-19) has evolved rapidly since the onset of the pandemic. In this Review, we discuss the hepatotropism of SARS-CoV-2, including the differential expression of viral receptors on liver cell types, and we describe the liver histology features present in patients with COVID-19. We also provide an overview of the pattern and relevance of abnormal liver biochemistry during COVID-19 and present the possible underlying direct and indirect mechanisms for liver injury. Furthermore, large international cohorts have been able to characterize the disease course of COVID-19 in patients with pre-existing chronic liver disease. Patients with cirrhosis have particularly high rates of hepatic decompensation and death following SARS-CoV-2 infection and we outline hypotheses to explain these findings, including the possible role of cirrhosis-associated immune dysfunction. This finding contrasts with outcome data in pharmacologically immunosuppressed patients after liver transplantation who seem to have comparatively better outcomes from COVID-19 than those with advanced liver disease. Finally, we discuss the approach to SARS-CoV-2 vaccination in patients with cirrhosis and after liver transplantation and predict how changes in social behaviours and clinical care pathways during the pandemic might lead to increased liver disease incidence and severity.

Outcomes following SARS-CoV-2 infection in patients with chronic liver disease: An international registry study.

BACKGROUND & AIMS: Chronic liver disease (CLD) and cirrhosis are associated with immune dysregulation, leading to concerns that affected patients may be at risk of adverse outcomes following SARS-CoV-2 infection. We aimed to determine the impact of COVID-19 on patients with pre-existing liver disease, which currently remains ill-defined. METHODS: Between 25th March and 8th July 2020, data on 745 patients with CLD and SARS-CoV-2 (including 386 with and 359 without cirrhosis) were collected by 2 international registries and compared to data on non-CLD patients with SARS-CoV-2 from a UK hospital network. RESULTS: Mortality was 32% in patients with cirrhosis compared to 8% in those without (p <0.001). Mortality in patients with cirrhosis increased according to Child-Pugh class (A [19%], B [35%], C [51%]) and the main cause of death was from respiratory failure (71%). After adjusting for baseline characteristics, factors associated with death in the total CLD cohort were age (odds ratio [OR] 1.02; 1.01-1.04), Child-Pugh A (OR 1.90; 1.03-3.52), B (OR 4.14; 2.4-7.65), or C (OR 9.32; 4.80-18.08) cirrhosis and alcohol-related liver disease (OR 1.79; 1.03-3.13). Compared to patients without CLD (n = 620), propensity-score-matched analysis revealed significant increases in mortality in those with Child-Pugh B (+20.0% [8.8%-31.3%]) and C (+38.1% [27.1%-49.2%]) cirrhosis. Acute hepatic decompensation occurred in 46% of patients with cirrhosis, of whom 21% had no respiratory symptoms. Half of those with hepatic decompensation had acute-on-chronic liver failure. CONCLUSIONS: In the largest such cohort to date, we demonstrate that baseline liver disease stage and alcohol-related liver disease are independent risk factors for death from COVID-19. These data have important implications for the risk stratification of patients with CLD across the globe during the COVID-19 pandemic. LAY SUMMARY: This international registry study demonstrates that patients with cirrhosis are at increased risk of death from COVID-19. Mortality from COVID-19 was particularly high among patients with more advanced cirrhosis and those with alcohol-related liver disease.

Outcomes following SARS-CoV-2 infection in liver transplant recipients: an international registry study.

BACKGROUND: Despite concerns that patients with liver transplants might be at increased risk of adverse outcomes from COVID-19 because of coexisting comorbidities and use of immunosuppressants, the effect of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection on this patient group remains unclear. We aimed to assess the clinical outcomes in these patients. METHODS: In this multicentre cohort study, we collected data on patients with laboratory-confirmed SARS-CoV-2 infection, who were older than 18 years, who had previously received a liver transplant, and for whom data had been submitted by clinicians to one of two international registries (COVID-Hep and SECURE-Cirrhosis) at the end of the patient's disease course. Patients without a known hospitalisation status or mortality outcome were excluded. For comparison, data from a contemporaneous cohort of consecutive patients with SARS-CoV-2 infection who had not received a liver transplant were collected from the electronic patient records of the Oxford University Hospitals National Health Service Foundation Trust. We compared the cohorts with regard to several outcomes (including death, hospitalisation, intensive care unit [ICU] admission, requirement for intensive care, and need for invasive ventilation). A propensity score-matched analysis was done to test for an association between liver transplant and death. FINDINGS: Between March 25 and June 26, 2020, data were collected for 151 adult liver transplant recipients from 18 countries (median age 60 years [IQR 47-66], 102 [68%] men, 49 [32%] women) and 627 patients who had not undergone liver transplantation (median age 73 years [44-84], 329 [52%] men, 298 [48%] women). The groups did not differ with regard to the proportion of patients hospitalised (124 [82%] patients in the liver transplant cohort vs 474 [76%] in the comparison cohort, p=0·106), or who required intensive care (47 [31%] vs 185 [30%], p=0·837). However, ICU admission (43 [28%] vs 52 [8%], p<0·0001) and invasive ventilation (30 [20%] vs 32 [5%], p<0·0001) were more frequent in the liver transplant cohort. 28 (19%) patients in the liver transplant cohort died, compared with 167 (27%) in the comparison cohort (p=0·046). In the propensity score-matched analysis (adjusting for age, sex, creatinine concentration, obesity, hypertension, diabetes, and ethnicity), liver transplantation did not significantly increase the risk of death in patients with SARS-CoV-2 infection (absolute risk difference 1·4% [95% CI -7·7 to 10·4]). Multivariable logistic regression analysis showed that age (odds ratio 1·06 [95% CI 1·01 to 1·11] per 1 year increase), serum creatinine concentration (1·57 [1·05 to 2·36] per 1 mg/dL increase), and non-liver cancer (18·30 [1·96 to 170·75]) were associated with death among liver transplant recipients. INTERPRETATION: Liver transplantation was not independently associated with death, whereas increased age and presence of comorbidities were. Factors other than transplantation should be preferentially considered in relation to physical distancing and provision of medical care for patients with liver transplants during the COVID-19 pandemic.

Burden and Cost of Gastrointestinal, Liver, and Pancreatic Diseases in the United States: Update 2018.

BACKGROUND & AIMS: Estimates of disease burden can inform national health priorities for research, clinical care, and policy. We aimed to estimate health care use and spending among gastrointestinal (GI) (including luminal, liver, and pancreatic) diseases in the United States. METHODS: We estimated health care use and spending based on the most currently available administrative claims from commercial and Medicare Supplemental plans, data from the GI Quality Improvement Consortium Registry, and national databases. RESULTS: In 2015, annual health care expenditures for gastrointestinal diseases totaled $135.9 billion. Hepatitis ($23.3 billion), esophageal disorders ($18.1 billion), biliary tract disease ($10.3 billion), abdominal pain ($10.2 billion), and inflammatory bowel disease ($7.2 billion) were the most expensive. Yearly, there were more than 54.4 million ambulatory visits with a primary diagnosis for a GI disease, 3.0 million hospital admissions, and 540,500 all-cause 30-day readmissions. There were 266,600 new cases of GI cancers diagnosed and 144,300 cancer deaths. Each year, there were 97,700 deaths from non-malignant GI diseases. An estimated 11.0 million colonoscopies, 6.1 million upper endoscopies, 313,000 flexible sigmoidoscopies, 178,400 upper endoscopic ultrasound examinations, and 169,500 endoscopic retrograde cholangiopancreatography procedures were performed annually. Among average-risk persons aged 50-75 years who underwent colonoscopy, 34.6% had 1 or more adenomatous polyps, 4.7% had 1 or more advanced adenomatous polyps, and 5.7% had 1 or more serrated polyps removed. CONCLUSIONS: GI diseases contribute substantially to health care use in the United States. Total expenditures for GI diseases are $135.9 billion annually-greater than for other common diseases. Expenditures are likely to continue increasing.

Transporter-Mediated Alterations in Patients With NASH Increase Systemic and Hepatic Exposure to an OATP and MRP2 Substrate.

The expression of hepatic transporters, including organic anion transporting polypeptides (OATPs) and multidrug resistance-associated proteins (MRPs), is altered in nonalcoholic steatohepatitis (NASH); however, functional data in humans are lacking. In this study, 99m Tc-mebrofenin (MEB) was used to evaluate OATP1B1/1B3 and MRP2 function in NASH patients. Healthy subjects (n = 14) and NASH patients (n = 7) were administered MEB (∼2.5 mCi). A population pharmacokinetic model was developed to describe systemic and hepatic MEB disposition. Study subjects were genotyped for SLCO1B1 variants. NASH increased systemic and hepatic exposure (median ± 2 SE, healthy vs. NASH) to MEB (AUC0-300,blood : 1,780 ± 242 vs. 2,440 ± 775 µCi*min/L, P = 0.006; AUC0-180,liver : 277 ± 36.9 vs. 433 ± 40.3 kcounts*min/sec, P < 0.0001) due to decreased biliary clearance (0.035 ± 0.008 vs. 0.017 ± 0.002 L/min, P = 0.0005) and decreased Vcentral (11.1 ± 0.57 vs. 6.32 ± 1.02 L, P < 0.0001). MEB hepatic CLuptake was reduced in NASH and also in healthy subjects with SLCO1B1 *15/*15 and *1A/*15 genotypes. The pharmacokinetics of drugs that are OATP1B1/1B3 and MRP2 substrates may be substantially altered in NASH.

Burden of Gastrointestinal, Liver, and Pancreatic Diseases in the United States.

BACKGROUND & AIMS: Gastrointestinal (GI), liver, and pancreatic diseases are a source of substantial morbidity, mortality, and cost in the United States. Quantification and statistical analyses of the burden of these diseases are important for researchers, clinicians, policy makers, and public health professionals. We gathered data from national databases to estimate the burden and cost of GI and liver disease in the United States. METHODS: We collected statistics on health care utilization in the ambulatory and inpatient setting along with data on cancers and mortality from 2007 through 2012. We included trends in utilization and charges. The most recent data were obtained from the Centers for Disease Control and Prevention, the Agency for Healthcare Research and Quality, and the National Cancer Institute. RESULTS: There were 7 million diagnoses of gastroesophageal reflux and almost 4 million diagnoses of hemorrhoids in the ambulatory setting in a year. Functional and motility disorders resulted in nearly 1 million emergency department visits in 2012; most of these visits were for constipation. GI hemorrhage was the most common diagnosis leading to hospitalization, with >500,000 discharges in 2012, at a cost of nearly $5 billion dollars. Hospitalizations and associated charges for inflammatory bowel disease, Clostridium difficile infection, and chronic liver disease have increased during the last 20 years. In 2011, there were >1 million people in the United States living with colorectal cancer. The leading GI cause of death was colorectal cancer, followed by pancreatic and hepatobiliary neoplasms. CONCLUSIONS: GI, liver and pancreatic diseases are a source of substantial burden and cost in the United States.
