INTRODUCTION: Alcohol-associated hepatitis (AH) is a severe condition with high short-term mortality. Identifying key predictors of poor outcomes is critical for guiding therapeutic strategies. Mean arterial pressure (MAP), a key determinant of tissue perfusion and systemic hemodynamics, may play a pivotal role in prognosis. METHODS: We analyzed a multicenter, prospective cohort of 323 patients hospitalized with AH, with validation in an independent cohort of 290 patients. Survival was evaluated using Kaplan-Meier curves and compared with the log-rank (Mantel-Cox) test. Cox proportional hazards models were used to estimate hazard ratios for mortality, adjusted for Model for end stage liver disease score. Mechanistic insights were explored through assessment of cardiovascular biomarkers. RESULTS: A baseline MAP <80 mm Hg was associated with significantly higher mortality at both 28 days (27.3% vs 8.0%) and 90 days (40.3% vs 15.6%; P < 0.001 for both). This association persisted after adjusting for Model for end stage liver disease score, age, and baseline hepatic encephalopathy. The incidence of infections during follow-up was similar across MAP groups (27.6% vs 22.8%), but acute kidney injury occurred more frequently in the MAP <80 mm Hg group (62% vs 38%, P < 0.001). In the validation cohort, patients with MAP <80 mm Hg also demonstrated significantly lower 28-day transplant-free survival. Although B-type natriuretic peptide and plasma renin levels were altered in patients with AH, they did not correlate with MAP values. DISCUSSION: A baseline MAP <80 mm Hg is an independent predictor of short-term and mid-term mortality in patients with AH. Strategies aimed at restoring hemodynamic stability may improve outcomes in this high-risk population.

Abstract Background Recurrent alcohol use is a major determinant of liver‐related outcomes in patients recovering from alcohol‐associated hepatitis (AH). However, the timing and predictors of return to drinking (RTD) are not well‐studied. Methods We analyzed alcohol use among patients with AH enrolled in two AlcHepNet multicenter studies: a Phase 2b randomized controlled trial and a prospective observational study. TimeLine FollowBack (TLFB) assessed drinking at each visit. RTD was defined as any alcohol use since the previous visit. The cumulative incidence of RTD was evaluated using the Fine–Gray method, with death as a competing risk. Factors associated with RTD were evaluated using univariate and multivariate Cox regression. Results Among 518 patients alive at Day 28, RTD occurred in 7.7%, 21.7%, and 30.8% at 30, 90, and 180 days, respectively. Patients with moderate AH (mAH, MELD 11–19, n = 103) had a higher RTD incidence at 180 days than those with severe AH (sAH, MELD ≥20, n = 415) (44.3% vs. 27.5%; p = 0.01). RTD was associated with higher AUDIT scores, family history of alcohol use disorder (AUD), lower education, greater alcohol use at baseline, lower MELD scores, and less ascites (all p ≤ 0.01). In multivariable analysis, >20 drinking days in the prior month was associated with increased risk of RTD (HR: 3.46, 95% CI: 2.21–5.39), whereas college education or higher was protective (HR: 0.53, 95% CI: 0.32–0.88). Conclusion RTD occurred in 22% of AH patients within 90 days postrecovery, highlighting the need for early AUD interventions. Frequent drinking days at baseline and lower education were strongly linked to early RTD.

Abstract Objective To evaluate the effect of erenumab treatment beyond monthly migraine days in patients with high‐frequency episodic migraine who did not respond to at least one previous migraine preventive treatment. Background Reduction in monthly migraine days has been the efficacy standard for migraine preventive treatments; however, it does not fully capture the holistic benefit of the therapy. Erenumab, a monoclonal antibody targeting the calcitonin gene–related peptide pathway, has demonstrated reduction in monthly migraine days and improvement in function in patients with episodic and chronic migraine. Methods In this phase 4, interventional, double‐blind, randomized, placebo‐controlled, multicenter, global study, treatment with erenumab was assessed over 4 months in adults with high‐frequency episodic migraine. The study was conducted at 61 sites located across North America and Europe between September 2020 and October 2023. Patients with ≥1 qualifying oral triptan‐treated migraine attack at baseline were randomized to receive erenumab 140 mg or placebo subcutaneously once monthly. The primary endpoint was change from baseline in mean monthly hours of at least moderate headache pain intensity over months 1, 2, and 3; secondary endpoints included change from baseline in mean monthly function, mean monthly duration of at least moderate pain intensity in migraine attacks, and mean monthly peak migraine pain intensity. Safety outcomes were also assessed. Results Of 512 randomized patients, 510 received erenumab 140 mg ( n = 254) or placebo ( n = 256) once monthly. Demographics and baseline characteristics were balanced between the two treatment arms. Erenumab 140 mg was superior to placebo in reducing duration of moderate or severe headache pain intensity over months 1, 2, and 3 (least squares mean [95% confidence interval {CI}] difference, −7.95 [−11.45, −4.46]; p < 0.001). Compared with placebo, erenumab significantly reduced migraine functional impact as assessed by the four domains of the Migraine Functional Impact Questionnaire, with a least squares mean (95% CI) difference of −7.36 (−10.80, −3.92) for physical functioning, −7.10 (−10.34, −3.87) for usual activities, −6.82 (−10.37, −3.27) for social functioning, and − 7.05 (−10.76, −3.34) for emotional functioning ( p < 0.001 for all domains). Significant reductions with erenumab compared with placebo were also observed in duration of at least moderate pain intensity in residual or break‐through migraine attacks (least squares mean [95% CI] difference, −1.07 [−1.92, −0.22]; p = 0.013) and peak migraine pain intensity (−0.48 [−0.85, −0.11]; p = 0.011). Incidence of grade 3 adverse events was 1.6% with erenumab and 1.2% with placebo; no grade 4 or fatal adverse events were reported in either treatment arm. Conclusion Findings from the EMBRACE study demonstrated that treatment with erenumab in patients with high‐frequency episodic migraine can provide positive therapeutic effects on ictal burden and pain, with residual migraine attacks tending to be shorter and less painful, with less overall impact.

Background & Aims: The clinical course and outcomes of alcohol-associated hepatitis (AH) remain poorly understood. Major adverse liver outcomes do not capture the added risk of return to drinking. We examined the natural history of AH and developed a composite endpoint using a contemporary observational cohort of AH. Approach & Results: A cohort of 1127 participants: 712 AH patients, 256 heavy drinking controls without clinically evident liver disease, and 159 healthy controls, were prospectively followed for 6 months at 8 United States centers as part of the Alcoholic Hepatitis Network (AlcHepNet) consortium. Outcomes included mortality and a composite endpoint (AlcHepNet composite index) that included death, liver transplantation, hepatic decompensation (new onset/worsening ascites, HE, variceal bleeding), liver-related hospital admission, MELD increase ≥5, and return to drinking. Of 712 AH patients (age 45±10.7 y; 59.1% male), 558 (79.0%) had severe and 148 (21.0%) had moderate AH, 232 (32.5%) died, and 86 (12.1%) underwent liver transplantation. Mortality rates in moderate AH and severe AH were 0.7% versus 17.2% (30 d), 3.4% versus 26.5% (90 d), and 8.8% versus 30.5% (180 d), respectively (all p <0.001). Composite liver/alcohol use events were noted in 459 (64.5%) AH patients. Higher MELD score, lower mean arterial pressure, and baseline leukocytosis were associated with higher 90-day mortality in AH (all p <0.05). College education and higher ALP were associated with lower mortality. Heavy drinking controls had low mortality (n=3; 1.2%). Conclusions: This large observational study showed a high incidence of composite liver and alcohol-use events within 6 months, reiterating the need for early interventions.

ABSTRACTBackgroundErenumab‐induced medication overuse headache (MOH) remission in participants with chronic migraine (CM) in a prospective, Phase 4, randomized, placebo‐controlled trial with an open‐label treatment period (OLTP). We present 1‐year results from the combined double‐blind treatment period (DBTP) and OLTP for the stratified nonopioid cohort.MethodsParticipants with CM‐MOH were randomized 1:1:1 to subcutaneous 70 or 140 mg erenumab every 4 weeks (QM) or placebo for the initial 24 weeks (DBTP). Those successfully completing DBTP could continue the 28‐week OLTP, maintaining the same erenumab dose received during DBTP or, if receiving placebo, randomly assigned 1:1 to erenumab 70 or 140 mg QM. OLTP endpoints were exploratory.ResultsOverall, 552 participants received erenumab (70 mg, n = 274; 140 mg, n = 278); 95.3% completed OLTP. One‐year MOH relapse in participants who achieved MOH remission at DBTP Month 6 was 2.7% (3/111) and 2.4% (3/124) with erenumab 70 and 140 mg, respectively; absence of MOH at study end was observed in 69.0% (189/274) and 75.5% (210/278) of participants. Sustained MOH absence over 1 year was reported in 60.5% (107/177) and 68.8% (119/173) of participants, respectively. Sustained improvements in measures of headache days, medication days, and function were observed in both groups. No new safety concerns were identified (grade ≥ 3, 35 [6.3%]; serious, 17 [3.1%]; adverse events leading to treatment discontinuation, 5 [0.9%]).ConclusionsErenumab was effective in inducing and sustaining MOH remission and improving function over 1 year. Treatment compliance remained high, with safety events consistent with erenumab's known safety profile.Trial RegistrationNCT03971071

Background: How parental alcohol use disorder and liver disease-related mortality influence the risk and the outcomes of alcohol-associated hepatitis (AH) in the offspring is unknown. Methods: We analyzed data from 2 prospective observational studies of AH cases and heavy drinking controls (HDCs). Family history of parental alcohol use disorder and liver disease mortality was assessed at the study entry. Logistic regression and Cox proportional hazard models were used to assess the influences of family history on AH development and outcome. Results: Data from 1356 participants in two prospective cohorts (926 AH cases and 430 HDC) were combined and analyzed. Parental alcohol use disorder was found in 56.9% of AH cases and 61.1% of HDC; parental death due to liver disease was reported in 7.5% of AH cases and 5.7% of HDC. Multivariable logistic regression showed that parental liver disease-related mortality was associated with more than a doubled risk of AH development in the offspring after controlling for their demographic characteristics and drinking behavior (OR=2.26, 95% CI: [1.22, 4.20]). Moreover, among the AH cases, having a parent die of liver disease significantly increased the 90-day mortality of study participants after adjusting for the effects of other risk factors (HR=2.26, 95% CI: [1.05, 4.86]). Conclusions: The study highlights the influences of parental death due to liver disease on AH development and mortality. Identifying patients at risk of AH through family history might help facilitate discussions on reducing alcohol consumption.

ImportancePatients with chronic migraine and medication overuse headaches (CM-MOH) represent a particularly burdened subpopulation. This trial provides first, to our knowledge, American Academy of Neurology class I evidence for a preventive therapy in CM-MOH.ObjectiveTo assess erenumab efficacy and safety in patients with nonopioid CM-MOH.Design, Settings, and ParticipantsThis randomized, double-blind, parallel-group, placebo-controlled trial took place at 67 centers in North America, Europe, and Australia from October 7, 2019, to November 2, 2022. This report reflects the primary analysis conducted in January 2023, using a database snapshot from December 1, 2022, which contains the complete dataset of the double-blind treatment period (DBTP). Participants included adults with CM-MOH who had 1 or more preventive treatment failure(s). There were 992 participants screened and 620 participants enrolled (584 in nonopioid cohort and 36 in opioid cohort)InterventionsErenumab, 70 mg, 140 mg, or placebo, once monthly for 24 weeks.Main Outcomes and MeasuresThe primary end point was MOH remission at month 6. Secondary end points included change from baseline in mean monthly acute headache medication days (AHMD) at month 6 and sustained MOH remission throughout the DBTP. Safety end points were adverse events and changes in vital signs.ResultsThe primary analysis population included 584 participants in the nonopioid-treated cohort with a mean age of 44 years and 482 participants were female (82.5%). Baseline demographics and disease characteristics were balanced across groups. At month 6, 134 participants in the erenumab, 140 mg group (69.1%) (odds ratio [OR], 2.01; 95% CI, 1.33-3.05; P &amp;lt; .001 vs placebo) and 117 in the erenumab, 70 mg group (60.3%) (OR, 1.37; 95% CI, 0.92-2.05; P = .13 vs placebo) achieved MOH remission vs 102 participants in the placebo group (52.6%). AHMD use was also reduced in the erenumab groups vs placebo. Least squares mean (standard error) change from baseline in average monthly AHMD was –9.4 (0.4) days in the erenumab, 140 mg group (difference from placebo, –2.7; 95% CI, –3.9 to –1.6; P &amp;lt; .001) and –7.8 (0.4) days in the erenumab, 70 mg group (difference from placebo, –1.2; 95% CI, –2.4 to –0.1; P = .03), vs –6.6 (0.4) days in the placebo group. MOH remission throughout the DBTP was sustained in 119 participants (61.3%,) 96 participants (49.5%), and 73 participants (37.6%) in the erenumab, 140 mg, 70 mg, and placebo groups, respectively. Adverse events were consistent with the known safety profile of erenumab. Treatment-emergent adverse events incidence in the combined erenumab group was 66.8% (259 participants; constipation 15.2% (59 participants) and COVID-19 13.9% (54 participants) were most common.Conclusions and RelevanceIn this study, monthly, 140 mg, erenumab injections safely and effectively achieved MOH remission in patients with nonopioid CM-MOH within 6 months.Trial RegistrationClinicalTrials.gov Identifier: NCT03971071

Background and Aims: In a recent trial, patients with severe alcohol-associated hepatitis treated with anakinra plus zinc (A+Z) had lower survival and higher acute kidney injury (AKI) rates versus prednisone (PRED). We characterize the clinical factors and potential mechanisms associated with AKI development in that trial. Approach and Results: Data from 147 participants in a multicenter randomized clinical trial (74 A+Z, 73 PRED) were analyzed. AKI, AKI phenotypes, and kidney injury biomarkers were compared between participants who did/did not develop AKI in the 2 treatment arms. Multivariable competing risk analyses were performed to identify baseline risk factors for incident AKI, with death treated as a competing event. Risk factors considered were age, sex, mean arterial pressure, white blood cell count, albumin, MELD, ascites, HE, and treatment arm. At baseline, no participants had AKI; 33% (n=49) developed AKI during follow-up. AKI incidence was higher in A+Z than in PRED (45% [n=33] versus 22% [n=16], p=0.001). AKI phenotypes were similar between the 2 treatment arms (p=0.361), but peak AKI severity was greater in A+Z than PRED (stage 3 n=21 [63.6%] vs. n=8 [50.0%], p=0.035). At baseline, urine-neutrophil-gelatinase–associated lipocalin levels were similar between participants who developed AKI in both treatment arms (p=0.319). However, day 7 and 14 urine-neutrophil-gelatinase–associated lipocalin levels were significantly elevated in participants treated with A+Z who developed AKI versus participants treated with PRED who developed AKI (p=0.002 and 0.032, respectively). On multivariable competing risk analysis, only A+Z was independently associated with incident AKI (subdistribution hazard ratio 2.35, p=0.005). Conclusions: AKI occurred more frequently and was more severe in participants treated with A+Z. A+Z–treated participants with AKI had higher urine-neutrophil-gelatinase–associated lipocalin, suggesting that A+Z maybe nephrotoxic in patients with severe alcohol-associated hepatitis.

Abstract Alcohol‐associated liver disease (ALD) is emerging worldwide as the leading cause of liver‐related morbidity, mortality, and indication for liver transplantation. The ALD Special Interest Group and the Clinical Research Committee at the digital American Association for the Study of Liver Diseases meeting in November 2020 held the scientific sessions to identify clinical unmet needs in ALD, and addressing these needs using clinical research methodologies. Of several research methodologies, the sessions were focused on (a) studying disease burden of ALD using large administrative databases, (b) developing biomarkers for noninvasive diagnosis of alcohol‐associated hepatitis (AH) and estimation of disease prognosis, (c) identifying therapeutic targets for ALD and AH, (d) deriving accurate models to predict prognosis or posttransplant alcohol relapse as a basis for developing treatment algorithm and a uniform protocol on patient‐selection criteria for liver transplantation, and (e) examining qualitative research methodologies in studying the barriers to implementation of multidisciplinary integrated care model by hepatology and addiction teams for the management of dual pathology of liver disease and of alcohol use disorder. Prospective multicenter studies are required to address many of these clinical unmet needs. Further, multidisciplinary care models are needed to improve long‐term outcomes in patients with ALD.

Acute on chronic liver failure (ACLF) is the culmination of chronic liver disease and extrahepatic organ failures, which is associated with a high short‐term mortality and immense health care expenditure. There are varying definitions for organ failures and ACLF in Europe, North America, and Asia. These differing definitions need to be reconciled to enhance progress in the field. The pathogenesis of ACLF is multifactorial and related to interactions between the immunoinflammatory system, microbiota, and the various precipitating factors. Individual organ failures related to the kidney, brain, lungs, and circulation have cumulative adverse effects on mortality and are often complicated or precipitated by infections. Strategies to prevent and rapidly treat these organ failures are paramount in improving survival. With the aging population and paucity of organs for liver transplant, the prognosis of ACLF patients is poor, highlighting the need for novel therapeutic strategies. The role of liver transplant in ACLF is evolving and needs further investigation across large consortia. A role for early palliative care and management of frailty as approaches to alleviate disease burden and improve patient‐reported outcomes is being increasingly recognized. Conclusion: ACLF is a clinically relevant syndrome that is epidemic worldwide and requires a dedicated multinational approach focused on prognostication and management; investigations are underway worldwide to prepare ACLF for prime time.
