RESUMEN
INTRODUCTION: Acamprosate is a therapy for alcohol use disorder but data on feasibility and safety in liver transplant (LT) recipients are lacking. METHODS: This was a single-center unblinded prospective pilot randomized controlled trial of adults (≥18 years) with LT for ALD enrolled between 2021-2023 who were randomized 2:1 to the intervention of acamprosate (666mg dose three times daily) or standard of care (SOC) over 14 weeks. Outcomes included safety [prevalence of adverse events (AE)], feasibility (weekly survey response rate >60%), adherence (self-reported acamprosate use>60%), and efficacy (reduction in Penn Alcohol Craving Scale [PACS]) and relapse-blood phosphatidylethanol≥20ng/mL/reported alcohol use) evaluated by standardized weekly surveys. The efficacy analysis was done in both the intention to treat (ITT) (excluding withdrawals before medication administration) and per-protocol (PP) population (excluding withdrawals/<4 weeks participation). RESULTS: Of 78 participants approached, 30 enrolled (19 acamprosate, 11 SOC) with similar baseline characteristics. Eight participants withdrew (6 acamprosate prior to medication administration and 2 SOC). AEs were similar between acamprosate and SOC groups (92.3% vs. 90.0%, p>0.99), including Grade 3 AEs (53.9% vs. 60.0%, p>0.99) with no reported grade 4/5 AEs. Survey response rates were similar in acamprosate vs SOC groups (61.0% vs. 76.0%, p=0.19), and 69.0% were acamprosate adherent. Baseline PACS values were low with no difference by group in median absolute change in PACS for ITT (0, IQR:-4-0 vs. 0, IQR:0-0, p=0.32) and PP analyses (-1, IQR:-6-0 vs. 0, IQR:0-0, p=0.36). There were no reported or biochemical evidence of alcohol relapse. CONCLUSION: In this pilot study, preliminary data suggests that acamprosate may be safe and feasible. These data can inform larger studies and clinician efforts to address alcohol use disorder in post-LT care. (ClinicalTrials.gov, Number: NCT06471686).
RESUMEN
BACKGROUND&AIMS: Globally, emergency departments (ED) are experiencing rising costs and crowding. Despite its importance, ED utilization and outcomes among patients with cirrhosis are understudied. METHODS: We analyzed Optum's de-identified Clinformatics® Data Mart Database, between 2008-2022, including adults with at least 180 days of enrollment. Liver transplant recipients were censored at the year of transplant. ED visits (stratified by liver vs non-liver related) were identified using validated billing code definitions. Linear regression was used to assess ED visits per year and logistic regression was used to assess 90-day mortality rates and discharge dispositions, with models adjusted for patient- and visit-level characteristics. RESULTS: Among 38,419,650 patients, 198,439 were with cirrhosis (median age 66[IQR 57-72]; 54% male; 62% white). In age-adjusted analysis, ED visits per person-year were 1.72[95CI 1.71-1.74] with cirrhosis vs 0.46[0.46-0.46] without cirrhosis, 1.66[1.66-1.66] for congestive heart failure (CHF), and 1.22[1.22-1.22] for chronic obstructive pulmonary disease (COPD). Age-adjusted 90-day mortality rates were 12.2%[95CI 12.1-12.4] with cirrhosis vs 4.8%[4.8-4.8] without cirrhosis, 6.9%[6.9-6.9] for CHF, and 6.3%[6.3-6.4] for COPD. Non-liver (vs liver-related) ED visits were more likely to lead to discharge home among patients with compensated (52.8%[52.2-53.5] vs 39.2% [38.5-39.8]) and decompensated (42.2%[41.5-42.8] vs 29.5%[29.0-30.1]) cirrhosis. In exploratory analysis, among patients who remained alive and were not readmitted for 30-days after ED discharge, those without any outpatient follow-up had higher 90-day mortality (22.0%[21.0-23.0]) than those with both primary care and gastroenterology/hepatology follow-up within 30-days (7.9%[7.3-8.5]). CONCLUSIONS: Patients with cirrhosis have higher ED utilization and almost 2-fold higher post-ED visit mortality than CHF and COPD. These findings provide impetus for ED-based interventions to improve cirrhosis-related outcomes.
RESUMEN
INTRODUCTION: While ubiquity of glucagon-like peptide receptor agonists (GLP1-RAs) is rising, guidance from the gastroenterology societies and American Society of Anesthesiologist (ASA) remains in conflict on recommendations regarding preoperative holding before endoscopy. The aim of this study was to address this by evaluating the effect of GLP1-RAs on gastric retention during upper endoscopy. METHODS: This multicenter cross-sectional study included patients on confirmed GLP1-RAs receiving an endoscopy from 2021 to 2023. Demographics, prescribing practices, and procedure outcomes were captured. GLP1-RA management of preoperative holding was retroactively classified per ASA guidance. Multivariable logistic regression was performed to assess factors influencing retained gastric contents. RESULTS: Of 815 patients, 70 (8.7%) had retained gastric contents on endoscopy of whom 65 (93%) had type 2 diabetes mellitus. Only 1 (1.4%) of these patients required unplanned intubation, and none had aspiration events. Those with GLP1-RA held per ASA guidance (406, 49.8%) were less likely to have retained contents (4.4% vs 12.7%, P < 0.001), but there were no significant differences to intubation (0% vs 2%, P = 0.53) or aborting procedure rates (28% vs 18%, P = 0.40) due to gastric retention. On multivariable analysis, likelihood of food retention increased 36% (95% confidence interval 1.15-1.60) for every 1% increase in hemoglobin A1C after adjusting for GLP1-RA type and preoperative medication hold. DISCUSSION: In this multicenter study, very low rates of retained gastric contents were seen during endoscopy in patients on GLP1-RAs and most were in patients with type 2 diabetes mellitus. Our findings suggest an individualized approach rather than universal preoperative holding of medications before endoscopy.
RESUMEN
INTRODUCTION: Early (i.e., without mandated period of abstinence) liver transplant (LT) for alcohol-associated hepatitis is the fastest-growing indication for LT in the United States and Europe. Harmful alcohol use after LT is associated with poor outcomes, but the distinction of establishing abstinence after return to drinking (i.e., reabstinence) is understudied. This study aims to characterize the survival outcomes of achieving reabstinence after post-LT harmful alcohol use. METHODS: We analyzed early LT recipients from 12 US LT centers between 2006 and 2021. Post-LT alcohol use was characterized as harmful using criteria of "binge" (≥5 [men] or ≥4 [women] drinks in < 24 hours) or "frequent" (≥4 days in one week) by interview or phosphatidylethanol >20 ng/mL. Reabstinence was defined as ≥12 consecutive months without harmful alcohol use after harmful alcohol use. RESULTS: Among 347 LT recipients (64% male, median age 43, median Model for End-Stage Liver Disease-Sodium score 38) with median post-LT follow-up of 2.2 years (interquartile interval 1.1-3.6), 276 (80%) recipients had no evidence of harmful alcohol use, 35 (10%) recipients had reabstinence, and 36 (10%) recipients had continued harmful alcohol use without reabstinence. Five-year predicted survival, adjusted for age, sex, and Model for End-Stage Liver Disease-Sodium score, was lowest among LT recipients with continued harmful alcohol use (77%), but similar among those with no harmful use (93%) and reabstinence (94%). DISCUSSION: Achieving reabstinence after post-LT harmful alcohol use is associated with similar 5-year post-LT survival compared with those without evidence of post-LT harmful alcohol use. Our findings highlight the importance of early detection and treatment of post-LT alcohol use.
RESUMEN
BACKGROUND: Liver transplantation (LT) for alcohol-associated liver disease (ALD) is increasing and may impact LT outcomes for patients listed for HCC and other indications. METHODS: Using US adults listed for primary LT (grouped as ALD, HCC, and other) from October 8, 2015, to December 31, 2021, we examined the impact of center-level ALD LT volume (ATxV) on waitlist outcomes in 2 eras: Era 1 (6-month wait for HCC) and Era 2 (MMaT-3). The tertile distribution of ATxV (low to high) was derived from the listed candidates as Tertile 1 (T1): <28.4%, Tertile 2 (T2): 28.4%-37.6%, and Tertile 3 (T3): >37.6% ALD LTs per year. Cumulative incidence of waitlist death and LT within 18 months from listing by LT indication were compared using the Gray test, stratified on eras and ATxV tertiles. Multivariable competing risk regression estimated the adjusted subhazard ratios (sHRs) for the risk of waitlist mortality and LT with interaction effects of ATxV by LT indication (interaction p). RESULTS: Of 56,596 candidates listed, the cumulative waitlist mortality for those with HCC and other was higher and their LT probability was lower in high (T3) ATxV centers, compared to low (T1) ATxV centers in Era 2. However, compared to ALD (sHR: 0.92 [0.66-1.26]), the adjusted waitlist mortality for HCC (sHR: 1.15 [0.96-1.38], interaction p = 0.22) and other (sHR: 1.13 [0.87-1.46], interaction p = 0.16) were no different suggesting no differential impact of ATxV on the waitlist mortality. The adjusted LT probability for HCC (sHR: 0.89 [0.72-1.11], interaction p = 0.08) did not differ by AtxV while it was lower for other (sHR: 0.82 [0.67-1.01], interaction p = 0.02) compared to ALD (sHR: 1.04 [0.80-1.34]) suggesting a differential impact of ATxV on LT probability. CONCLUSIONS: The high volume of LT for ALD does not impact waitlist mortality for HCC and others but affects LT probability for other in the MMAT-3 era warranting continued monitoring.

BACKGROUND: The role of endoscopic mucosal resection (EMR) for laterally spreading lesions (LSLs) in inflammatory bowel disease (IBD) remains controversial despite its effectiveness in the general population. We aim to characterize outcomes of EMR for IBD-associated LSLs compared to controls without IBD. METHODS: We performed a retrospective observational cohort study of patients with IBD who underwent EMR and endoscopic follow-up for LSLs, compared to a control group without IBD. The primary outcome was histologic recurrence; secondary outcomes included en bloc resection and adverse events. Factors associated with recurrence were identified using multivariate mixed effects logistic regression. RESULTS: A total of 210 pre-malignant lesions in 155 patients were included. By histology, 91% were adenoma/low-grade dysplasia or sessile serrated lesions. Average lesion size was 22.9 mm (SD 11.3 mm) in the IBD group, and 21.5 mm (SD 12.4 mm) in the control group. Recurrence occurred in 30.4% of IBD-associated lesions (7/23) compared to 20.9% of controls (39/187; OR=2.51, CI .59-10.71). En bloc resection was less common in the IBD group (2/23, 8.7%, 95% CI 1.1-28.0) versus controls (106/187, 57.9%, 95% CI 50.4-65.2). After adjusting for lesion size and histology, recurrence appeared more common in patients with IBD compared to controls (OR=3.08, 95% CI 1.04-9.13). CONCLUSIONS: Recurrence of LSLs after EMR appears more frequent in patients with IBD. Given the added complexity, EMR in patients with IBD should be performed in expert centers with close endoscopic surveillance.
RESUMEN
INTRODUCTION: The National Institute on Minority Health and Health Disparities has noted that transgender individuals experience unique health disparities. We sought to describe the landscape of transgender patients with cirrhosis. METHODS: We identified all transgender and cisgender adults in Optum's deidentified Clinformatics Data Mart Database between 2007 and 2022 using validated billing codes and calculating age-standardized prevalence of cirrhosis among cisgender vs transgender adults. Among those with incident cirrhosis diagnoses, we calculated age-standardized incidence densities of liver-related outcomes (decompensation, transplantation, hepatocellular carcinoma) and all-cause mortality. We examined 5-year survival using inverse probability treatment weighting to balance transgender and cisgender populations on demographic and clinical characteristics. RESULTS: Among 64,615,316 adults, 42,471 (0.07%) were transgender. Among 329,251 adults with cirrhosis, 293 (0.09%) were transgender. Trans- (vs cis-) genders had higher prevalence of cirrhosis (1,285 [95% confidence interval (CI) 1,136-1,449] per 100,000 vs 561 [559-563] per 100,000). Among adults with cirrhosis, trans- (vs cis-) genders had higher proportions of anxiety (70.7% [56.9-86.9] vs 43.2% [42.7-43.8]), depression (66.4% [53.3-81.7] vs 38.4% [37.9-38.9]), HIV/AIDS (8.5% [3.9-16.1] vs 1.6% [1.5-1.7]), and alcohol (57.5% [46.0-71.1] vs 51.0% [50.5-51.6]) and viral (30.5% [22.8-39.8] vs 24.2% [23.9-24.5]) etiologies, although etiologies had overlapping CIs. Trans- (vs cis-) genders had similar incidence densities of death (12.0 [95% CI 8.8-15.3] vs 14.0 [13.9-14.2] per 100 person-years), decompensation (15.7 [10.9-20.5] vs 14.1 [14.0-14.3]), and liver transplantation (0.3 [0.0-0.8] vs 0.3 [0.3-0.4]). In inverse probability treatment weighting survival analysis, transgender and cisgender individuals had similar 5-year survival probabilities (63.4% [56.6-71.1] vs 59.1% [58.7-59.4]). DISCUSSION: Trans- (vs cis-) gender adults have double the prevalence of cirrhosis, and the majority have a diagnosis of anxiety and/or depression. These results are informative for researchers, policymakers, and clinicians to advance equitable care for transgender individuals.
RESUMEN
BACKGROUND & AIMS: Large language models including Chat Generative Pretrained Transformers version 4 (ChatGPT4) improve access to artificial intelligence, but their impact on the clinical practice of gastroenterology is undefined. This study compared the accuracy, concordance, and reliability of ChatGPT4 colonoscopy recommendations for colorectal cancer rescreening and surveillance with contemporary guidelines and real-world gastroenterology practice. METHODS: History of present illness, colonoscopy data, and pathology reports from patients undergoing procedures at 2 large academic centers were entered into ChatGPT4 and it was queried for the next recommended colonoscopy follow-up interval. Using the McNemar test and inter-rater reliability, we compared the recommendations made by ChatGPT4 with the actual surveillance interval provided in the endoscopist's procedure report (gastroenterology practice) and the appropriate US Multisociety Task Force (USMSTF) guidance. The latter was generated for each case by an expert panel using the clinical information and guideline documents as reference. RESULTS: Text input of de-identified data into ChatGPT4 from 505 consecutive patients undergoing colonoscopy between January 1 and April 30, 2023, elicited a successful follow-up recommendation in 99.2% of the queries. ChatGPT4 recommendations were in closer agreement with the USMSTF Panel (85.7%) than gastroenterology practice recommendations with the USMSTF Panel (75.4%) (P < .001). Of the 14.3% discordant recommendations between ChatGPT4 and the USMSTF Panel, recommendations were for later screening in 26 (5.1%) and for earlier screening in 44 (8.7%) cases. The inter-rater reliability was good for ChatGPT4 vs USMSTF Panel (Fleiss κ, 0.786; 95% CI, 0.734-0.838; P < .001). CONCLUSIONS: Initial real-world results suggest that ChatGPT4 can define routine colonoscopy screening intervals accurately based on verbatim input of clinical data. Large language models have potential for clinical applications, but further training is needed for broad use.

BACKGROUND AND AIMS: Second-generation direct-acting antivirals (2G DAA) to cure HCV have led to dramatic clinical improvements. HCV-associated hepatocellular carcinoma (HCC), however, remains common. Impaired immune tumor surveillance may play a role in HCC development. Our cohort evaluated the effects of innate immune types and clinical variables on outcomes including HCC. METHODS: Participants underwent full HLA class I/KIR typing and long-term HCV follow-up. RESULTS: A total of 353 HCV+ participants were followed for a mean of 7 years. Cirrhosis: 25% at baseline, developed in 12% during follow-up. 158 participants received 2G DAA therapy. HCC developed without HCV therapy in 20 subjects, 24 HCC after HCV therapy, and 10 of these after 2G DAA. Two predictors of HCC among 2G DAA-treated patients: cirrhosis (OR, 10.0, p = 0.002) and HLA/KIR profiles predicting weak natural killer (NK) cell-mediated immunity (NK cell complementation groups 6, 9, 11, 12, OR of 5.1, p = 0.02). Without 2G DAA therapy: cirrhosis was the main clinical predictor of HCC (OR, 30.8, p < 0.0001), and weak NK-cell-mediated immunity did not predict HCC. CONCLUSION: Cirrhosis is the main risk state predisposing to HCC, but weak NK-cell-mediated immunity may predispose to post-2G DAA HCC more than intermediate or strong NK-cell-mediated immunity.

Background: MELD 3.0 introduces changes to address waitlist disparities for liver transplant (LT) candidates. Ascites and hepatic encephalopathy (HE) are important milestones in the natural history of cirrhosis regardless of the Model for End-Stage Liver Disease (MELD) score. We aim to assess the impact of ascites and HE and its interaction with MELD 3.0 on waitlist mortality. Methods: This is a retrospective study of patients listed for LT in the Organ Procurement and Transplantation Network database from 2016 to 2021. The primary outcome was waitlist mortality (death/delisting for too sick to LT). Ascites/HE were classified as moderate ascites without moderate HE (mAscites), moderate HE without moderate ascites (mHE), both moderate ascites/HE (mBoth), and neither. MELD 3.0 scores were categorized as <20, 20-29, 30-39, and ≥40. Results: Of 39 025 candidates, 29% had mAscites, 3% mHE, and 8% mBoth. One-year waitlist mortality was 30%, 38%, and 47%, respectively, compared with 17% (all Pâ <â 0.001) for those with neither. In multivariable Cox regression, the adjusted risk of waitlist mortality associated with mAscites (versus neither) was a hazard ratio (HR) of 1.76 (95% confidence interval [CI], 1.55-2.00) when the MELD 3.0 score was <20, significantly higher than when the MELD 3.0 score was 20-29 (HR 1.40; 95% CI, 1.27-1.54), 30-39 (HR 1.19; 95% CI, 1.04-1.35), and ≥40â (HR 1.14; 95% CI, 0.91-1.43, interaction Pâ <â 0.05 for all). A similar pattern was observed by MELD 3.0 for both moderate ascites/HE. Conclusions: The presence of moderate ascites alone, or combined with moderate HE, not only increases the risk of waitlist mortality but also has a differential effect by MELD 3.0, especially at lower MELD scores. Earlier strategies addressing this group and improving treatment plans or access to LT regardless of MELD remain needed.
RESUMEN
BACKGROUND & AIMS: While renin-angiotensin system inhibition lowers the hepatic venous gradient, the effect on more clinically meaningful endpoints is less studied. We aimed to quantify the relationship between renin-angiotensin system inhibition and liver-related events (LREs) among adults with compensated cirrhosis. METHODS: In this national cohort study using the Optum database, we quantified the association between angiotensin-converting enzyme (ACE) inhibitor or angiotensin-receptor blocker (ARB) use and LREs (hepatocellular carcinoma, liver transplantation, ascites, hepatic encephalopathy, or variceal bleeding) among patients with cirrhosis between 2009 and 2019. Selective beta-blocker (SBB) users served as the comparator group. We used demographic and clinical features to calculate inverse-probability treatment weighting-weighted cumulative incidences, absolute risk differences, and Cox proportional hazard ratios. RESULTS: Among 4214 adults with cirrhosis, 3155 were ACE inhibitor/ARB users and 1059 were SBB users. In inverse probability treatment weighting-weighted analyses, ACE inhibitor/ARB (vs SBB) users had lower 5-year cumulative incidence (30.6% [95% confidence interval (CI), 27.8% to 33.2%] vs 41.3% [95% CI, 34.0% to 47.7%]; absolute risk difference, -10.7% [95% CI, -18.1% to -3.6%]) and lower risk of LREs (adjusted hazard ratio [aHR], 0.69; 95% CI, 0.60 to 0.80). There was a dose-response relationship: compared with SBB use, ACE inhibitor/ARB prescriptions ≥1 defined daily dose (aHR, 0.65; 95% CI, 0.56 to 0.76) were associated with a greater risk reduction compared with <1 defined daily dose (aHR, 0.87; 95% CI, 0.71 to 1.07). Results were robust across sensitivity analyses such as comparing ACE inhibitor/ARB users with nonusers and as-treated analysis. CONCLUSIONS: In this national cohort study, ACE inhibitor/ARB use was associated with significantly lower risk of LREs in patients with compensated cirrhosis. These results provide support for a randomized clinical trial to confirm clinical benefit.

BACKGROUND AND AIMS: The multisociety consensus nomenclature has renamed NAFLD to steatotic liver disease (SLD) with various subclassifications. There is a paucity of data regarding how the new nomenclature modifies our understanding of disease prevalence and patient phenotypes. APPROACH AND RESULTS: Using the National Health and Nutrition Examination Survey from January 2017 to March 2020, we included all participants aged 18 years or above with complete vibration-controlled transient elastography measures. SLD and its subclassifications [metabolic dysfunction-associated SLD (MASLD), MASLD + increased alcohol intake (MetALD), alcohol-associated liver disease (ALD), etiology-specific/cryptogenic] were defined according to consensus nomenclature. National SLD prevalence and subclassifications were estimated, and among key subgroups [age, sex, race/ethnicity, advanced liver fibrosis (liver stiffness measurement [LSM] ≥11.7 kPa)]. Among 7367 participants, 2549 had SLD (mean age 51 y, 57.7% male, 63.2% non-Hispanic White). The estimated prevalence of SLD was 34.2% (95% CI 31.9%-36.5%): MASLD 31.3% (29.2%-33.4%), MetALD 2% (1.6%-2.9%), ALD 0.7% (0.5-0.9%), etiology-specific/cryptogenic 0.03% (0.01%-0.08%). In exploratory analyses, participants classified as non-SLD with (vs. without) advanced fibrosis had a higher mean number of metabolic risk factors [2.7 (2.3-3.1) vs. 2.0 (1.9-2.0)] and a higher proportion with average alcohol use ≥20 g/d (women)/≥30 g/d (men) [20.9% (6.2%-51.3%) vs. 7.2% (6.1%-8.4%)]. In another exploratory analysis, increasing quantities of alcohol use remaining below the threshold for MASLD + increased alcohol intake were associated with advanced liver fibrosis in men, but not women. There was 99% overlap in cases of NAFLD and MASLD. CONCLUSIONS: Our findings highlight the utility of the new consensus nomenclature to address deficiencies present with the old nomenclature, and identify areas that require research to further refine classifications of SLD.

BACKGROUND AND AIMS: To examine neighborhood-level disparities in waitlist mortality for adult liver transplantation (LT), we developed novel area-based social determinants of health (SDOH) index using a national transplant database. METHODS: ZIP Codes of individuals listed for or received LT in the Scientific Registry of Transplant Recipients database between June 18, 2013, and May 18, 2019, were linked to 36 American Community Survey (ACS) variables across 5 SDOH domains for index development. A step-wise principal component analysis was used to construct the Liver Outcomes and Equity (LOEq) index. We then examined the association between LOEq quintiles (Q1 = worst and Q5 = best neighborhood SDOH) and waitlist mortality with competing risk regression among listed adults in the study period and acuity circle (AC) era. RESULTS: The final LOEq index consisted of 13 ACS variables. Of 59 298 adults waitlisted for LT, 30% resided in LOEq Q5 compared with only 14% in Q1. Q1 neighborhoods with worse SDOH were disproportionately concentrated in transplant regions with low median Model for End-Stage Liver Disease at transplant (MMAT) and shorter wait times. Five years cumulative incidence of waitlist mortality was 33% in Q1 in high MMAT regions versus 16% in Q5 in low MMAT regions. Despite this allocation advantage, LOEq Q1-Q4 were independently associated with elevated risk of waitlist mortality compared with Q5, with highest increased hazard of waitlist deaths of 19% (95% CI, 11%-26%) in Q1. This disparity persisted in the AC era, with 24% (95% CI, 10%-40%) increased hazard of waitlist deaths for Q1 versus Q5. CONCLUSIONS: Neighborhood SDOH independently predicts waitlist mortality in adult LT.
RESUMEN
INTRODUCTION: Absolute polymorphonuclear leukocyte (PMN) count (PMN-C) ≥250 cells/mm 3 in ascites is the diagnostic hallmark of spontaneous bacterial peritonitis (SBP) and is associated with high morbidity and mortality. However, the clinical significance of ascitic PMN percentage (PMN-%) and PMN-C in the absence of SBP as additional biomarkers for mortality and future incidence of SBP has not been determined. METHODS: This retrospective cohort included adults with cirrhosis undergoing first-recorded paracentesis with initial PMN-C < 250 cells/mm 3 at 2 tertiary medical centers between 2015 and 2020. Patients with prior SBP were excluded. Outcomes were death and SBP development. Cox regression estimated hazard ratios (HRs) for risk of death and SBP development and Akaike information criterion to compare model fit. RESULTS: Three hundred eighty-four adults (73% male, median age 58 years, 67% with alcohol-associated cirrhosis, median PMN-C 14 cells/mm 3 [interquartile range 5-34], and median PMN-% 10% [interquartile range 4-20]) were included in this study. Univariate risk of death increased 10% per 25-unit increase in PMN-C (95% confidence interval 1.01-1.21, P = 0.03) and 19% per 10-unit increase in PMN-% (95% confidence interval 1.06-1.33, P = 0.003) with PMN-% demonstrating better model fit in assessing mortality risk (Akaike information criterion: 1,044 vs 1,048, respectively). In models adjusted for age, chronic hepatitis C virus infection, and Model for End-Stage Liver Disease-Sodium, PMN-% was associated with risk of death (PMN-% 10%-29%, HR 1.17, P = 0.50; PMN-% ≥ 30% group, HR 1.94, P = 0.03; vs PMN-% < 10%) and SBP development (PMN-% 10%-29%, HR 1.68, P = 0.07; PMN-% ≥ 30%, HR 3.48, P < 0.001; vs PMN-% < 10%). DISCUSSION: Our results suggest PMN-% at first paracentesis represents a better biomarker compared with PMN-C for assessing risk of death and future SBP development in patients with PMN-C < 250 cells/mm 3 .

INTRODUCTION: Immigrants comprise a considerable proportion of those diagnosed with hepatocellular carcinoma (HCC) in the United States. Nativity or birthplace affects incidence and risk factors for HCC, but little is known about its influence on survival after diagnosis. METHODS: We identified 51â533 adults with HCC with available birthplace in the California Cancer Registry between 1988 and 2017. HCC cases were categorized as foreign born or US born and stratified by mutually exclusive race and ethnicity groups. Primary outcome was all-cause mortality. Race and ethnicity-specific Cox regression propensity score-weighted models evaluated the relationship between nativity and death as well as region of birth among foreign-born patients. RESULTS: A total of 40% of all HCC cases were foreign born, and 92.2%, 45.2%, 9.1%, and 5.8% of Asian/Pacific Islander (API), Hispanic, White, and Black patients were foreign born, respectively. Five-year survival rates were higher in foreign-born patients compared with US-born patients: 12.9% vs 9.6% for White patients, 11.7% vs 9.8% for Hispanic patients, 12.8% vs 8.1% for Black patients, and 16.4% vs 12.4% for API patients. Nativity was associated with survival, with better survival in foreign-born patients: White patients: hazard ratio (HR) = 0.86 (95% confidence interval [CI] = 0.81 to 0.90), Hispanic patients: HR = 0.90 (95% CI = 0.86 to 0.93), Black patients: HR = 0.89 (95% CI = 0.76 to 1.05), and API patients: HR = 0.94 (95% CI = 0.88 to 1.00). Among foreign-born patients, lower mortality was observed in those from Central and South America compared with Mexico for Hispanic patients, East Asia compared with Southeast Asia for API patients, and East Europe and Greater Middle East compared with West/South/North Europe for White patients. CONCLUSION: Foreign-born patients with HCC have better survival than US-born patients. Further investigation into the mechanisms of this survival disparity by nativity is needed.

BACKGROUND: Predicting the risk of alcohol relapse after a liver transplant for alcohol-associated liver disease is critical to guide candidate selection and optimize alcohol use disorder management. We aimed to use patient survey to augment the detection of alcohol relapse and its risk factors and to understand patient perceptions of the importance of alcohol abstinence. METHODS: In this retrospective cohort study, we used a telephone survey and chart review to assess the incidence of post-transplant harmful alcohol relapse, risk factors, and long-term outcomes for patients transplanted for alcohol-associated cirrhosis at our center from 2002 to 2016. RESULTS: Over the median follow-up of 5.9 years, 20.4% relapsed, with 9.3% harmful relapse after median of 4.0 years. The survey response rate was 44.0% (n=110). Of survey responders, 44.3% did not recall discussing alcohol in post-transplant clinics, and 17.6% of relapses were identified by the survey alone. In univariate analysis, shorter pretransplant sobriety (OR: 0.96 per month, p=0.02) and history of pretransplant relapse (OR: 2.99, p=0.02) were associated with post-transplant harmful relapse. After adjusting for these factors, High-risk Alcoholism Relapse score ≥4 predicted harmful relapse (OR: 3.43, p=0.049). A total of 27.3% of patients with both pretransplant relapse and High-risk Alcoholism Relapse score ≥4 relapsed to harmful use compared with 5.2% of those with 1 or neither risk factor (p < 0.001). Harmful relapse was associated with increased graft loss (30.4% vs. 17.4%) and inferior 10-year post-liver transplant survival (61.5% vs. 80.7%). CONCLUSIONS: Incorporating patient survey data allowed the detection of relapses otherwise unreported to clinicians, highlighting the need for novel strategies to detect relapse. Utilizing this augmented data, we identified pretransplant sobriety length, pretransplant relapse, and High-risk Alcoholism Relapse score ≥4 as risk factors that should be evaluated pretransplant to guide candidate selection and peritransplant alcohol use disorder management.

BACKGROUND AND AIMS: Lifestyle factors are well associated with risk of hepatocellular carcinoma (HCC). However, the impact of reducing adverse lifestyle behaviours on population-level burden of HCC is uncertain. METHODS: We conducted prospective analysis of the population-based multi-ethnic cohort (MEC) with linkage to cancer registries. The association of lifestyle factors (smoking, alcohol, diet quality assessed by alternate Mediterranean diet score, coffee drinking, physical activity and body mass index) with HCC incidence was examined using Cox regression. Population-attributable risk (PAR, %) for the overall, lean and overweight/obese populations was determined. RESULTS: A total of 753 incident cases of HCC were identified in 181,346 participants over median follow-up of 23.1 years. Lifestyle factors associated with elevated HCC risk included former/current smoking, heavy alcohol use, poor diet quality, lower coffee intake and obesity, but not physical activity. The lifestyle factor with highest PAR was lower coffee intake (21.3%; 95% CI: 8.9%-33.0%), followed by current smoking (15.1%; 11.1%-19.0%), obesity (14.5%; 9.2%-19.8%), heavy alcohol use (7.1%; 3.5%-10.6%) and lower diet quality (4.1%; 0.1%-8.1%). The combined PAR of all high-risk lifestyle factors was 51.9% (95% CI: 30.1%-68.6%). A higher combined PAR was observed among lean (65.2%, 26.8%-85.7%) compared to overweight/obese (37.4%, 11.7%-58.3%) participants. Adjusting for viral hepatitis status in a linked MEC-Medicare dataset resulted in similar PAR results. CONCLUSIONS: Modifying lifestyle factors, particularly coffee intake, may have a substantial impact on HCC burden in diverse populations, with greater impact among lean adults. Diet and lifestyle counselling should be incorporated into HCC prevention strategies.
