International expert panel review for the use of resmetirom and semaglutide in the management of MASH-related fibrosis: clinical practice update.

New therapyMASLDguideline
Clinical takeawayPracticing GIs can now offer pharmacological treatment for MASH F2-F3 using resmetirom or semaglutide. This expert panel provides decision support for drug selection by patient phenotype, initiation protocols, on-treatment monitoring, response assessment, dose adjustment, and criteria for combining or switching agents.
What it foundResmetirom (thyroid hormone receptor-beta agonist) and semaglutide (GLP-1 RA) are the first FDA-approved pharmacological treatments for MASH F2-F3, marking the first therapy option for a previously untreated condition; expert panel consolidates phase III trial data and clinical guidance for their use.
ContextMASH F2-F3 previously had no pharmacological options. Resmetirom and semaglutide are the first FDA-approved agents for this indication, acting through complementary mechanisms. This expert consolidation replaces a prior era of supportive care alone with a structured clinical decision framework.

Decision at stakechoosing between resmetirom and semaglutide for MASH with F2-F3 fibrosis and assessing on-treatment response

For adults with MASH and F2-F3 fibrosis identified by non-invasive tests (VCTE 8-15 kPa, MRE 3.1-4.4 kPa, or ELF 9.2-10.5) rather than biopsy, AASLD now gives dedicated, updated practice guidance on both FDA-approved pharmacotherapies: resmetirom (Oct 2024 update) and semaglutide 2.4mg/week subcutaneous (Nov 2025 update, following August 2025 accelerated FDA approval based on ESSENCE trial data: 62.9% vs 34.3% MASH resolution without fibrosis worsening; 36.8% vs 22.4% ≥1-stage fibrosis improvement).

Our full summary of this standard

Diagnose MASLD by hepatic steatosis on imaging (or biopsy) plus at least one cardiometabolic criterion and exclusion of competing etiologies (significant alcohol use, other liver disease), then risk-stratify fibrosis using a sequential non-invasive approach: FIB-4 first, followed by a second-line imaging-based test (VCTE, MRE, or ELF) for indeterminate/high-risk FIB-4, with liver biopsy reserved for discordant or unclear cases. Lifestyle modification (≥7-10% weight loss, Mediterranean diet, exercise) remains the foundation for all patients. For adults with MASH and F2-F3 fibrosis identified by non-invasive tests (VCTE 8-15 kPa, MRE 3.1-4.4 kPa, or ELF 9.2-10.5) rather than biopsy, AASLD now gives dedicated, updated practice guidance on both FDA-approved pharmacotherapies: resmetirom (Oct 2024 update) and semaglutide 2.4mg/week subcutaneous (Nov 2025 update, following August 2025 accelerated FDA approval based on ESSENCE trial data: 62.9% vs 34.3% MASH resolution without fibrosis worsening; 36.8% vs 22.4% ≥1-stage fibrosis improvement). Pioglitazone or vitamin E remain options per the 2023 base guidance. Manage cardiometabolic risk with statins for ASCVD reduction plus glycemic and blood-pressure control; for semaglutide specifically, routine hepatic panels are recommended only as clinically indicated (no discontinuations for LFT elevation in ESSENCE), with monitoring for GI adverse effects and rare risks (AKI, gallbladder disease, pancreatitis, thyroid C-cell tumors, retinopathy progression, lean mass loss). HCC surveillance with ultrasound and AFP every 6 months remains indicated only if cirrhosis is present.

HBsAg decline and clearance with peg-IFN therapy added to nucleos(t)ide analogues: an individual participant data meta-analysis of prospective trials (PROSPER).

New evidenceviral hepatitismeta-analysis
Clinical takeawayIn HBV patients on nucleos(t)ides pursuing HBsAg clearance or cure strategies, peg-IFN add-on success depends on baseline level. Patients with baseline <100 had ~38% HBsAg loss rate; baseline <1000 (combined <100 and 100-1000 strata) had ~18%. For higher-baseline patients (≥1000), use peg-IFN as lead-in to achieve intermediate reductions (47.5% reach HBsAg <1000 at 48 weeks), supporting sequential cure regimens with novel antivirals.
What it foundPeg-IFN added to nucleos(t)ide analogues achieved HBsAg loss in 38% of patients with baseline <100 IU/mL and 18% with baseline <1000 IU/mL. For patients with baseline ≥1000 IU/mL, intermediate HBsAg reductions occurred more frequently: 48 weeks of peg-IFN achieved HBsAg <1000 in 47.5% and <100 in 16.3%. Overall HBsAg loss occurred in 50/581 (8.6%).
ContextIndividual participant data meta-analysis of 8 prospective trials (581 patients; 44% HBeAg-positive at baseline) providing baseline-stratified HBsAg loss rates and intermediate reduction milestones-useful data for patient selection in chronic hepatitis B.

Our full summary of this standard

The 2026 AASLD/IDSA guideline addresses six PICO questions only; it states explicitly that all other 2018 AASLD recommendations for CHB management remain applicable, and that screening/diagnosis were out of scope. Baseline evaluation and the standard treatment indications (cirrhosis with detectable HBV DNA; HBeAg-positive immune-active with ALT >2x ULN and HBV DNA >20,000 IU/mL; HBeAg-negative immune-active with ALT >2x ULN and HBV DNA >2,000 IU/mL; prophylaxis for reactivation risk during immunosuppression) derive from the 2018 document, not this update, which lists 'treatment of HBeAg-positive and -negative immune active CHB with ALT >2x ULN', treatment of children, treatment of cirrhosis, low-level viremia, virologic breakthrough, and special populations (transplant, acute HBV, HCV/HDV/HIV coinfection) as topics 'well covered in previous AASLD 2018 Guidance and for which recommendations have not changed'. Preferred agents remain entecavir, TDF, or TAF. THE SIX 2026 RECOMMENDATIONS: (1) PMTCT, for pregnant persons with HBV DNA >200,000 IU/mL at any time point during pregnancy, regardless of HBeAg status, AASLD RECOMMENDS initiating TDF or TAF at gestational week 28 (STRONG recommendation, MODERATE certainty, the only strong recommendation in the guideline); TDF has a more extensive safety record in pregnancy than TAF. Implementation qualifiers: initiate immediately if care is first sought after week 28; initiate at week 16 if infant HBIG will be unavailable (with subsequent infant vaccination); consider earlier initiation when amniocentesis is anticipated (transmission risk is increased with HBV DNA >2,000,000 IU/mL) or when preterm labor risk is high; continue TDF/TAF if already on it, switch entecavir or other agents to TDF/TAF; if treatment was solely for perinatal prophylaxis it may be discontinued at delivery, with HBV DNA and ALT monitored every 1-3 months for up to 6 months for withdrawal flare and treatment reinitiated if ALT >=5x ULN; use TDF or TAF in breastfeeding persons requiring treatment. (2) HORIZONTAL TRANSMISSION, for HBsAg-positive viremic persons not meeting disease-specific treatment indications who are in high-risk scenarios for transmission to others, AASLD SUGGESTS a shared decision-making approach regarding antiviral treatment (CONDITIONAL, VERY LOW certainty). Qualifiers the guideline stresses: the decision weighs exposure risk and the vaccine/immunity status of contacts, favoring treatment if contacts are unvaccinated, vaccine-nonresponsive, immunocompromised, or of unknown vaccine status; persons requesting treatment for prevention may be prescribed it since risks may not be disclosed; explicitly, people with CHB must NOT be restricted in daily activities, contact sports, school, or professional training and must NOT be required to take antivirals because of transmission risk in those settings; routine contact, shared meals, and hugging are not transmission routes (avoid sharing toothbrushes/razors); most healthcare workers with CHB are NOT high-risk, but those performing SHEA Category III exposure-prone procedures may require antivirals (SHEA target HBV DNA <1000 IU/mL); neither CDC nor SHEA requires disclosure to patients or staff; anti-stigma framing is part of the recommendation. (3) IMMUNE-TOLERANT PHASE, defined as HBeAg-positive, HBV DNA >10^7 IU/mL, and normal ALT; AASLD SUGGESTS antiviral therapy for those over age 40 years, OR with significant liver inflammation (grade >=2) or fibrosis (>=F2) on biopsy or noninvasive tests (CONDITIONAL, VERY LOW certainty). For persons under age 40 who are interested in starting treatment earlier, AASLD suggests shared decision-making weighing risk factors and the benefits and risks of treatment. Accurate phase identification requires persistently normal ALT on >=2 measurements >=6 months apart, using ULN 35 U/L (males) and 25 U/L (females). (4) INDETERMINATE ('grey zone') PHASE, the HBeAg-negative indeterminate phase is defined as HBsAg-positive, HBeAg-negative persons whose ALT and/or HBV DNA fall outside the thresholds for HBeAg-negative immune-active CHB (ALT >2x ULN and HBV DNA >2,000 IU/mL) and outside those for inactive CHB (HBV DNA <2,000 IU/mL with normal ALT), comprising predominantly two subgroups, (I) normal (<ULN) or mildly elevated (<2x ULN) ALT with HBV DNA >=2,000 IU/mL, or (II) elevated ALT (>ULN) with HBV DNA <2,000 IU/mL, with ALT interpreted against ULN 35 U/L (males) and 25 U/L (females) and phase assigned on >=2 ALT and HBV DNA measurements over a 6-12 month period; in adults who are HBsAg-positive, HBeAg-negative, without cirrhosis and in the indeterminate phase so defined, AASLD SUGGESTS antiviral therapy using a shared decision-making approach assessing risks and benefits, and re-evaluating that decision at each follow-up visit if treatment has not been initiated (CONDITIONAL, VERY LOW certainty). Decision-relevant factors include fibrosis stage, age, and sex, e.g. age >40, male sex, and low-normal platelets (<180 k/mm3) favor treatment. (5) DISCONTINUATION, in adults with CHB who are HBeAg-negative, without cirrhosis, with sustained undetectable HBV DNA on nucleos(t)ide analogue therapy, AASLD SUGGESTS NOT withdrawing NA therapy until HBsAg loss (CONDITIONAL, VERY LOW certainty). If a patient nonetheless has a strong desire to stop, shared decision-making applies and ALL of the following must be met: no history of advanced fibrosis/cirrhosis, hepatic decompensation (variceal bleed, ascites, encephalopathy, hepatorenal syndrome), HCC, or extrahepatic HBV complications; if HBeAg-positive at treatment start, HBeAg seroconversion to anti-HBe-positive for >=1 year with undetectable HBV DNA >=2 years; if HBeAg-negative at start, undetectable HBV DNA >=2 years; no HIV or HDV coinfection; quantitative HBsAg <100 IU/mL; and willingness to adhere to frequent monitoring. After stopping, monitor ALT and HBV DNA every 1-3 months for 6 months, then every 3 months for 6-12 months, then every 3-6 months. Restart antivirals IMMEDIATELY if HBV DNA >=10,000 IU/mL (4 log IU/mL) at any time regardless of ALT, OR ALT >=5x ULN regardless of HBV DNA, OR total bilirubin >2.5 mg/dL. (6) HCC SURVEILLANCE (all CONDITIONAL, VERY LOW certainty; modality/interval per AASLD 2023 HCC Practice Guidance), Rec 6: after HBsAg loss, continue surveillance in those with cirrhosis, family history of HCC, men who lost HBsAg after age 40, and women who lost HBsAg after age 50. Rec 7: in HBV-HDV coinfection, surveil adults independent of cirrhosis status; in children, individualize because HCC risk in that population is unknown. Rec 8: in HBV-HIV coinfection, surveil men >=18 years and women >=40 years. Rec 9: in HBV-HCV coinfection, AASLD recommends treating HCV and suggests HCC surveillance per HBV mono-infection criteria. Where a person has more than one coinfection, the surveillance recommendation should follow the coinfection carrying the highest associated risk. The guideline notes that most of its recommendations rest on low or very low certainty evidence and that shared decision-making, not uniform policy, is the intended mode of application.

Personalised prediction of the individual risk of liver-related events in MASLD using the dynamics of non-invasive tests.

New evidenceMASLDcirrhosishepatocellular carcinomaartificial intelligence
Clinical takeawayThe JLCM improves discrimination for cirrhosis decompensation and HCC risk within the VCTE-Prognosis cohort compared to static LSM or FIB-4 alone. Prospective external validation in independent MASLD populations and deployment of a validated risk calculator are required before recommending clinical use for surveillance intensity or treatment decisions.
What it foundJoint latent class model incorporating LSM trajectory, FIB-4, sex, age, and platelets identified 61-80% of patients who developed cirrhosis decompensation or HCC across follow-up visits, compared to 39-56% with LSM alone and 32-60% with FIB-4, achieving AUROC 92.2% at 5-year follow-up.
ContextThis literature reports that personalised risk prediction for liver-related events in MASLD can be derived from longitudinal trends in non-invasive fibrosis markers, addressing the clinical challenge of interpreting dynamic test changes.

Our full summary of this standard

Diagnose MASLD by hepatic steatosis on imaging (or biopsy) plus at least one cardiometabolic criterion and exclusion of competing etiologies (significant alcohol use, other liver disease), then risk-stratify fibrosis using a sequential non-invasive approach: FIB-4 first, followed by a second-line imaging-based test (VCTE, MRE, or ELF) for indeterminate/high-risk FIB-4, with liver biopsy reserved for discordant or unclear cases. Lifestyle modification (≥7-10% weight loss, Mediterranean diet, exercise) remains the foundation for all patients. For adults with MASH and F2-F3 fibrosis identified by non-invasive tests (VCTE 8-15 kPa, MRE 3.1-4.4 kPa, or ELF 9.2-10.5) rather than biopsy, AASLD now gives dedicated, updated practice guidance on both FDA-approved pharmacotherapies: resmetirom (Oct 2024 update) and semaglutide 2.4mg/week subcutaneous (Nov 2025 update, following August 2025 accelerated FDA approval based on ESSENCE trial data: 62.9% vs 34.3% MASH resolution without fibrosis worsening; 36.8% vs 22.4% ≥1-stage fibrosis improvement). Pioglitazone or vitamin E remain options per the 2023 base guidance. Manage cardiometabolic risk with statins for ASCVD reduction plus glycemic and blood-pressure control; for semaglutide specifically, routine hepatic panels are recommended only as clinically indicated (no discontinuations for LFT elevation in ESSENCE), with monitoring for GI adverse effects and rare risks (AKI, gallbladder disease, pancreatitis, thyroid C-cell tumors, retinopathy progression, lean mass loss). HCC surveillance with ultrasound and AFP every 6 months remains indicated only if cirrhosis is present.

Assessing Strategies to Mitigate the Effect of Age When Using FIB-4 Index to Screen for MASLD-Related Liver Fibrosis.

New evidenceMASLDbiomarkercirrhosis
Clinical takeawayIn MASLD patients at age extremes (<35 or ≥65 years), use FIB-3 (AST/ALT/platelet-based, age-omitted) instead of standard FIB-4 for fibrosis screening. It maintains equivalent diagnostic accuracy without the age-related bias that causes FIB-4 to underestimate risk in younger patients and overestimate in older patients, pending prospective confirmation for guideline adoption.
What it foundFIB-3 (age-removed from FIB-4; exact formula in source paper) maintained diagnostic accuracy of standard FIB-4 for detection of ≥F2 and ≥F3 MASLD fibrosis (AUROCs 0.76-0.78 vs MRE, 0.77-0.81 vs biopsy, all five strategies similar), while demonstrating improved sensitivity-specificity balance specifically at age extremes (<35 and ≥65 years).
ContextFIB-4 is guideline-recommended for MASLD screening but has known limitations at age extremes: the formula overestimates fibrosis in older patients and underestimates it in younger patients because age is a direct component. This study validates that removing age (FIB-3) maintains equivalent diagnostic accuracy while eliminating this bias, suggesting age-independent calculation could improve screening across age strata.

Pharmacokinetic and Pharmacodynamic Variability Predict Late Events After Paediatric Liver Transplantation: Derivation and External Validation of a Landmark Risk Score.

New evidenceliver transplantpediatricbiomarker
Clinical takeawayAt 12 months post-pediatric liver transplant in recipients without major early complications (6-12 months post-transplant), calculate tacrolimus, aspartate aminotransferase, and total bilirubin variability from prior 6 months of measurements; score of 2-3 identifies patients at 4-9x higher risk for late complications or graft loss, warranting closer surveillance. Population predominantly biliary atresia.
What it foundA variability-based risk score (tacrolimus >25%, aspartate aminotransferase >50%, total bilirubin >50%) derived and externally validated at 12 months post-transplant, where score 2-3 identified higher-risk patients with hazard ratio 4.48 (95% CI 1.79-11.17) in derivation and 8.90 (95% CI 2.66-29.81) in validation cohorts.
ContextChallenges the sufficiency of cross-sectional tacrolimus concentrations and static liver biochemistry in post-transplant monitoring. Demonstrates that longitudinal instability and variability are better predictors of adverse long-term outcomes. Derived and externally validated in pediatric recipients, predominantly with biliary atresia, without early major complications.

The Impact of HCC Surveillance on Tumor Features and Receipt of Curative Therapy: A Focus on Chronic Hepatitis B and MASLD.

New evidencehepatocellular carcinomaMASLDviral hepatitishealth services
Clinical takeawayEnsure HCC surveillance in cirrhotic patients, HBV carriers, and MASLD patients. Surveillance-diagnosed patients had 17.8-fold higher odds of receiving curative therapy, indicating earlier detection and better candidacy for potentially curative treatment. This reinforces guideline-recommended screening in at-risk populations; the finding that 72% of non-surveillance HCC cases had HBV and 54% had cirrhosis underscores real-world surveillance gaps despite guideline consensus.
What it foundHCC surveillance independently predicted curative therapy receipt (OR 17.78, 95% CI 5.56-56.88); in HBV carriers the effect was stronger (OR 26.79) and higher BMI also predicted curative receipt (OR 1.18 per unit). Surveillance-diagnosed patients presented with smaller tumors, lower rates of multifocal disease, and less vascular invasion.
ContextThis literature reports that hepatocellular carcinoma surveillance is associated with differences in tumor features and receipt of curative therapy in patients with chronic hepatitis B and MASLD.

Our full summary of this standard

The 2026 AASLD/IDSA guideline addresses six PICO questions only; it states explicitly that all other 2018 AASLD recommendations for CHB management remain applicable, and that screening/diagnosis were out of scope. Baseline evaluation and the standard treatment indications (cirrhosis with detectable HBV DNA; HBeAg-positive immune-active with ALT >2x ULN and HBV DNA >20,000 IU/mL; HBeAg-negative immune-active with ALT >2x ULN and HBV DNA >2,000 IU/mL; prophylaxis for reactivation risk during immunosuppression) derive from the 2018 document, not this update, which lists 'treatment of HBeAg-positive and -negative immune active CHB with ALT >2x ULN', treatment of children, treatment of cirrhosis, low-level viremia, virologic breakthrough, and special populations (transplant, acute HBV, HCV/HDV/HIV coinfection) as topics 'well covered in previous AASLD 2018 Guidance and for which recommendations have not changed'. Preferred agents remain entecavir, TDF, or TAF. THE SIX 2026 RECOMMENDATIONS: (1) PMTCT, for pregnant persons with HBV DNA >200,000 IU/mL at any time point during pregnancy, regardless of HBeAg status, AASLD RECOMMENDS initiating TDF or TAF at gestational week 28 (STRONG recommendation, MODERATE certainty, the only strong recommendation in the guideline); TDF has a more extensive safety record in pregnancy than TAF. Implementation qualifiers: initiate immediately if care is first sought after week 28; initiate at week 16 if infant HBIG will be unavailable (with subsequent infant vaccination); consider earlier initiation when amniocentesis is anticipated (transmission risk is increased with HBV DNA >2,000,000 IU/mL) or when preterm labor risk is high; continue TDF/TAF if already on it, switch entecavir or other agents to TDF/TAF; if treatment was solely for perinatal prophylaxis it may be discontinued at delivery, with HBV DNA and ALT monitored every 1-3 months for up to 6 months for withdrawal flare and treatment reinitiated if ALT >=5x ULN; use TDF or TAF in breastfeeding persons requiring treatment. (2) HORIZONTAL TRANSMISSION, for HBsAg-positive viremic persons not meeting disease-specific treatment indications who are in high-risk scenarios for transmission to others, AASLD SUGGESTS a shared decision-making approach regarding antiviral treatment (CONDITIONAL, VERY LOW certainty). Qualifiers the guideline stresses: the decision weighs exposure risk and the vaccine/immunity status of contacts, favoring treatment if contacts are unvaccinated, vaccine-nonresponsive, immunocompromised, or of unknown vaccine status; persons requesting treatment for prevention may be prescribed it since risks may not be disclosed; explicitly, people with CHB must NOT be restricted in daily activities, contact sports, school, or professional training and must NOT be required to take antivirals because of transmission risk in those settings; routine contact, shared meals, and hugging are not transmission routes (avoid sharing toothbrushes/razors); most healthcare workers with CHB are NOT high-risk, but those performing SHEA Category III exposure-prone procedures may require antivirals (SHEA target HBV DNA <1000 IU/mL); neither CDC nor SHEA requires disclosure to patients or staff; anti-stigma framing is part of the recommendation. (3) IMMUNE-TOLERANT PHASE, defined as HBeAg-positive, HBV DNA >10^7 IU/mL, and normal ALT; AASLD SUGGESTS antiviral therapy for those over age 40 years, OR with significant liver inflammation (grade >=2) or fibrosis (>=F2) on biopsy or noninvasive tests (CONDITIONAL, VERY LOW certainty). For persons under age 40 who are interested in starting treatment earlier, AASLD suggests shared decision-making weighing risk factors and the benefits and risks of treatment. Accurate phase identification requires persistently normal ALT on >=2 measurements >=6 months apart, using ULN 35 U/L (males) and 25 U/L (females). (4) INDETERMINATE ('grey zone') PHASE, the HBeAg-negative indeterminate phase is defined as HBsAg-positive, HBeAg-negative persons whose ALT and/or HBV DNA fall outside the thresholds for HBeAg-negative immune-active CHB (ALT >2x ULN and HBV DNA >2,000 IU/mL) and outside those for inactive CHB (HBV DNA <2,000 IU/mL with normal ALT), comprising predominantly two subgroups, (I) normal (<ULN) or mildly elevated (<2x ULN) ALT with HBV DNA >=2,000 IU/mL, or (II) elevated ALT (>ULN) with HBV DNA <2,000 IU/mL, with ALT interpreted against ULN 35 U/L (males) and 25 U/L (females) and phase assigned on >=2 ALT and HBV DNA measurements over a 6-12 month period; in adults who are HBsAg-positive, HBeAg-negative, without cirrhosis and in the indeterminate phase so defined, AASLD SUGGESTS antiviral therapy using a shared decision-making approach assessing risks and benefits, and re-evaluating that decision at each follow-up visit if treatment has not been initiated (CONDITIONAL, VERY LOW certainty). Decision-relevant factors include fibrosis stage, age, and sex, e.g. age >40, male sex, and low-normal platelets (<180 k/mm3) favor treatment. (5) DISCONTINUATION, in adults with CHB who are HBeAg-negative, without cirrhosis, with sustained undetectable HBV DNA on nucleos(t)ide analogue therapy, AASLD SUGGESTS NOT withdrawing NA therapy until HBsAg loss (CONDITIONAL, VERY LOW certainty). If a patient nonetheless has a strong desire to stop, shared decision-making applies and ALL of the following must be met: no history of advanced fibrosis/cirrhosis, hepatic decompensation (variceal bleed, ascites, encephalopathy, hepatorenal syndrome), HCC, or extrahepatic HBV complications; if HBeAg-positive at treatment start, HBeAg seroconversion to anti-HBe-positive for >=1 year with undetectable HBV DNA >=2 years; if HBeAg-negative at start, undetectable HBV DNA >=2 years; no HIV or HDV coinfection; quantitative HBsAg <100 IU/mL; and willingness to adhere to frequent monitoring. After stopping, monitor ALT and HBV DNA every 1-3 months for 6 months, then every 3 months for 6-12 months, then every 3-6 months. Restart antivirals IMMEDIATELY if HBV DNA >=10,000 IU/mL (4 log IU/mL) at any time regardless of ALT, OR ALT >=5x ULN regardless of HBV DNA, OR total bilirubin >2.5 mg/dL. (6) HCC SURVEILLANCE (all CONDITIONAL, VERY LOW certainty; modality/interval per AASLD 2023 HCC Practice Guidance), Rec 6: after HBsAg loss, continue surveillance in those with cirrhosis, family history of HCC, men who lost HBsAg after age 40, and women who lost HBsAg after age 50. Rec 7: in HBV-HDV coinfection, surveil adults independent of cirrhosis status; in children, individualize because HCC risk in that population is unknown. Rec 8: in HBV-HIV coinfection, surveil men >=18 years and women >=40 years. Rec 9: in HBV-HCV coinfection, AASLD recommends treating HCV and suggests HCC surveillance per HBV mono-infection criteria. Where a person has more than one coinfection, the surveillance recommendation should follow the coinfection carrying the highest associated risk. The guideline notes that most of its recommendations rest on low or very low certainty evidence and that shared decision-making, not uniform policy, is the intended mode of application.

Long-Term Major Adverse Liver Outcomes and Oncological Outcomes Across Steatotic Liver Disease Subtypes Classified Using the MetALD-ALD Prediction Index.

Epidemiologyhepatocellular carcinomaMASLDalcohol-associated liver diseaseepidemiology
Clinical takeawayIn UK Biobank participants free of cancer at baseline, ALD was associated with 1.70-fold higher MALO risk and 3.07-fold higher HCC risk compared with MASLD. MAPI specifics and classification thresholds live in the source. Alcohol underreporting may cause misclassification between MetALD and ALD. Prospective clinical utility and practical implementation for routine surveillance and referral decisions remain unvalidated.
What it foundAmong 138,996 SLD patients, ALD conferred 1.70-fold higher risk of major adverse liver outcomes and 3.07-fold higher hepatocellular carcinoma risk compared with MASLD; MetALD showed intermediate risks for cancer but not MALO.
ContextRetrospective risk stratification in a UK biobank cohort. Demonstrates distinct outcome risks by SLD subtype but does not establish prospective validity of MAPI as a practical classification tool for clinic-based use.

Decision at stakeWhether hepatocellular carcinoma surveillance should be intensified in alcohol-associated liver disease

For alcohol-associated hepatitis (AH), severity is stratified by MELD: MELD >20 defines severe AH, which carries high short-term mortality and should preferably be managed in hospital; MELD ≤20 defines moderate AH.

Our full summary of this standard

Treatment of AUD with sustained abstinence is the most effective strategy to prevent progression and improve long-term outcomes at any stage of ALD; ACG recommends brief screening with a tool such as AUDIT-C (strong, high), brief motivational interventions (strong, low), and integrated multidisciplinary care combining behavioral therapy and/or pharmacotherapy (strong, low). AUD pharmacotherapy recommendations are scoped specifically to COMPENSATED ALD and are not co-equal: baclofen is recommended as an option (strong recommendation, moderate evidence); acamprosate or naltrexone are only suggested as options (conditional, very low); gabapentin or topiramate are suggested as options (conditional, very low); disulfiram is suggested AGAINST along any spectrum of ALD (conditional, very low). For severe alcohol withdrawal, benzodiazepines are the treatment of choice but with explicitly cautious use and careful monitoring given their potential to precipitate or exacerbate hepatic encephalopathy (strong, moderate); AWS is managed per CIWA-Ar protocol, differentiating it from HE while acknowledging the two can coexist. For alcohol-associated hepatitis (AH), severity is stratified by MELD: MELD >20 defines severe AH, which carries high short-term mortality and should preferably be managed in hospital; MELD ≤20 defines moderate AH. In severe AH (MELD >20) ACG recommends corticosteroid therapy ONLY if there are no contraindications (strong, moderate); active infection (including untreated HBV infection), uncontrolled diabetes mellitus, gastrointestinal bleeding, and severe renal failure are contraindications to corticosteroid use, though corticosteroids can be started after adequate control or reversal of infection, renal failure, and gastrointestinal bleeding. Prednisolone is preferred over prednisone; both are dosed 40 mg/day for a total of 4 weeks, with IV methylprednisolone 32 mg/day as the alternative for patients unable to take oral medication; there is no evidence supporting rapid vs slow tapering after the 4-week course. Corticosteroid response is assessed by Lille score at day 7 OR day 4 (day-4 shown as accurate as day-7); among non-responders (Lille >0.45) corticosteroids should be discontinued. ACG recommends IV N-acetylcysteine as an adjuvant to corticosteroids in severe AH (strong, moderate), while explicitly noting that other society guidelines have not adopted this recommendation. ACG recommends AGAINST pentoxifylline (strong, moderate) and AGAINST universal prophylactic antibiotics in hospitalized severe AH (strong, moderate); data on G-CSF and microbiome-based therapies are insufficient. Nutrition: target 35 kcal/kg/day with 1.2-1.5 g/kg/day protein; patients consuming <21 kcal/kg/day should receive nutritional support, preferably oral/enteral, oral nutritional supplements first, escalating to enteral nutrition if caloric targets remain unmet (strong, moderate). Thiamine, vitamin B12 and zinc deficiencies are common in AH and should be supplemented. For severe AH unresponsive to medical management with high risk of death, early liver transplantation for highly selected patients should be considered according to regional and institutional protocols (conditional recommendation, low level of evidence); LT selection must not be based solely on an arbitrary duration of sobriety, and should rest on detailed psychosocial evaluation by a social worker and addiction specialist, optionally supported by tools such as SIPAT, HRAR, MAPS, HPSS or SALT. For severe AH with 4 or more organ failures, non-responsive to corticosteroids and ineligible for early LT, palliative care engagement is appropriate.

Clinical takeawayNo clinical action yet: this mechanistic review describes cell-level pathways and proposes ferroptosis-targeting strategies, but no human trial data, no validated diagnostic test, and no approved ferroptosis-modulating therapies exist for MASH.
What it foundFerroptosis-immune axis identified as a bidirectional amplifying circuit in MASH with a 4-gene signature (FABP4, CAPG, QSOX1, FXN) that maps the transition from early metabolic stress to advanced structural remodelling.
ContextAdvances mechanistic understanding of MASH by positioning ferroptosis and innate immune activation as a central reciprocal circuit rather than sequential progression, and integrates known genetic risk variants (PNPLA3, TM6SF2, MBOAT7) into a ferroptosis framework.

Our full summary of this standard

Diagnose MASLD by hepatic steatosis on imaging (or biopsy) plus at least one cardiometabolic criterion and exclusion of competing etiologies (significant alcohol use, other liver disease), then risk-stratify fibrosis using a sequential non-invasive approach: FIB-4 first, followed by a second-line imaging-based test (VCTE, MRE, or ELF) for indeterminate/high-risk FIB-4, with liver biopsy reserved for discordant or unclear cases. Lifestyle modification (≥7-10% weight loss, Mediterranean diet, exercise) remains the foundation for all patients. For adults with MASH and F2-F3 fibrosis identified by non-invasive tests (VCTE 8-15 kPa, MRE 3.1-4.4 kPa, or ELF 9.2-10.5) rather than biopsy, AASLD now gives dedicated, updated practice guidance on both FDA-approved pharmacotherapies: resmetirom (Oct 2024 update) and semaglutide 2.4mg/week subcutaneous (Nov 2025 update, following August 2025 accelerated FDA approval based on ESSENCE trial data: 62.9% vs 34.3% MASH resolution without fibrosis worsening; 36.8% vs 22.4% ≥1-stage fibrosis improvement). Pioglitazone or vitamin E remain options per the 2023 base guidance. Manage cardiometabolic risk with statins for ASCVD reduction plus glycemic and blood-pressure control; for semaglutide specifically, routine hepatic panels are recommended only as clinically indicated (no discontinuations for LFT elevation in ESSENCE), with monitoring for GI adverse effects and rare risks (AKI, gallbladder disease, pancreatitis, thyroid C-cell tumors, retinopathy progression, lean mass loss). HCC surveillance with ultrasound and AFP every 6 months remains indicated only if cirrhosis is present.

Blocking the gut-liver IgA axis attenuates macrophage-mediated inflammation and injury in alcohol-associated liver disease.

Basic sciencealcohol-associated liver diseasebasic sciencetranslational
Clinical takeawayNo clinical action yet: a mechanistic finding in ethanol-fed mice showing that IgA-macrophage axis inhibition reduces IL-1-linked inflammation and liver injury. IgA modulation has not been tested as an ALD therapy in humans.
What it foundIn ALD, serum IgA (median 323-412 mg/dL) was higher than in controls (194/211 mg/dL) and correlated with hepatic IgA-bound macrophages and IL-1β transcripts (ρ=0.383, p=0.008); in ethanol-fed mice, fingolimod reduced serum IgA, IgA-bound hepatic macrophages, IL-1β transcripts, and liver injury markers (ALT/AST p<0.05) versus ethanol-fed controls without fingolimod.
ContextCurrent ALD pathogenesis models emphasize LPS-driven TLR4 signaling and IL-1β inflammation from dysbiosis. This study proposes the IgA-macrophage axis as a bridge between dysbiotic microbiota and hepatic myeloid-cell activation, extending our mechanistic understanding but requiring human validation before clinical translation.

Parental obesity and risk of metabolic dysfunction associated steatotic liver disease in adult offspring: UK birth cohort study.

EpidemiologyMASLDepidemiologyobesity
Clinical takeawayParental obesity predicts offspring MASLD risk through cumulative childhood weight gain (67% of effect). In counseling, frame childhood weight management as potentially protective and modifiable, even with obese parents. No new screening, testing, or treatment for MASLD is directly supported by this observational association study.
What it foundEach 1 kg/m2 increase in maternal pre-pregnancy BMI raised offspring MASLD odds by 10% (OR 1.10, 95% CI 1.06-1.14); paternal BMI increase raised odds by 9% (OR 1.09, 95% CI 1.04-1.13). Both parents overweight or obese associated with 3.73-fold increased odds of offspring MASLD at age 24 (95% CI 2.43-5.73 vs. normal-BMI parents), with 67% of this association mediated by cumulative excess childhood BMI (area under the curve for BMI Z-score >1, ages 7-17).
ContextMaternal obesity → offspring metabolic disease is established; this adds paternal obesity (similar effect size) and clarifies the transmission pathway. The key refinement is that cumulative childhood BMI mediates 67% of the parental obesity association, suggesting childhood weight management (rather than accepting genetic predisposition) is modifiable. MASLD prevalence at age 24 (10.4%) reflects its epidemiologic dominance.

Heart-liver co-management in MASLD: expert perspectives and recommendations from a multidisciplinary cardiometabolic framework.

Guideline / reviewMASLDguidelinehealth services
Clinical takeawayCalls for systematic institutional coordination between gastroenterology and cardiology in MASLD assessment and management. No new patient-level intervention specified; implementation requires local protocol development to ensure all MASLD patients receive cardiovascular risk stratification and appropriate cardiology involvement.
What it foundMASLD management remains fragmented across specialties, with cardiovascular risk under-appreciated in hepatology and MASLD under-recognized in cardiology, despite availability of non-invasive tests (FIB-4, VCTE) and pharmacotherapies with dual liver-cardiovascular benefits (resmetirom, GLP-1 receptor agonists, SGLT2 inhibitors).
ContextConfirms MASLD carries substantial cardiovascular risk, but documents that this risk remains under-assessed in routine practice due to silos between gastroenterology and cardiology.

Spleen and liver two-dimensional shear wave elastography for clinically significant portal hypertension.

Diagnosticportal hypertensionbiomarker
Clinical takeawayIn compensated advanced chronic liver disease, combined liver and spleen elastography could help stratify CSPH risk, but clinical utility is limited by two factors: measurement reliability failure in 15-46% of patients and modest validation discrimination (AUROC 0.73). The high specificity (87.8%) at the high-risk threshold could identify patients more likely to have CSPH, potentially supporting a decision to proceed to HVPG measurement. However, sensitivity is unreported, overall discrimination does not exceed existing non-invasive scores in the same cohort, and measurement quality constraints complicate bedside implementation. Use remains complementary to HVPG, not a replacement.
What it foundSSI-4PH model (liver stiffness, spleen stiffness, platelet count, BMI) achieved AUROC 0.90 in derivation cohort but 0.73 in external validation (n=73) for detecting CSPH (HVPG ≥10 mmHg) in compensated advanced chronic liver disease; at ≥75% predicted-risk threshold, specificity was 87.8%. Reliable paired measurements (IQR/Med ≤30%) were available in only 54% of derivation and 85% of validation cohort. In validation, SSI-4PH performed worse than existing elastography scores (Anticipate-SSI AUROC 0.78, LPS-SSI 0.77).
ContextThis study, conducted in cACLD of unspecified etiology, confirms that combining liver and spleen elastography improves risk stratification beyond LSM alone. Existing non-invasive tools (Baveno VII, Anticipate-SSI, LPS-SSI) are validated in viral, alcohol-related, or non-obese MASLD; this work's population etiology, BMI distribution, and applicability to other etiologies or obese patients remain unspecified. External validation performance (AUROC 0.73) did not exceed established scores, and the high proportion of unreliable measurements (46% derivation) is a more severe barrier to implementation than prior elastography studies.

Decision at stakeHow to use non-invasive elastography to classify clinically significant portal hypertension risk in compensated advanced chronic liver disease

Risk-stratify compensated advanced chronic liver disease (cACLD) with non-invasive tests before defaulting to endoscopy. Clinically significant portal hypertension (CSPH, i.e. HVPG above 10 mm Hg) is ruled in non-invasively by LSM at or above 25 kPa alone, or LSM 20 to 24.9 kPa with platelets below 150 x 10^9/L, or LSM 15 to 19.9 kPa with platelets below 110 x 10^9/L.

From our summary of this standard, unedited — the part the paper bears on. marks omitted text. Our wording, not the guideline's; read the source for its own text.

Our full summary of this standard

Scope: this primary document covers portal hypertension and varices in cirrhosis ONLY. Everything else in the current entry (HCC surveillance, transplant referral, nutrition, vaccination, ascites/SBP/HE/HRS/ACLF management) belongs to the separate documents listed as supporting sources and must not be attributed to this guidance. Risk-stratify compensated advanced chronic liver disease (cACLD) with non-invasive tests before defaulting to endoscopy. By vibration-controlled transient elastography, liver stiffness (LSM) under 10 kPa excludes cACLD, 10 to 14.9 kPa is suggestive and warrants further testing, and 15 kPa or above rules cACLD in. Clinically significant portal hypertension (CSPH, i.e. HVPG above 10 mm Hg) is ruled in non-invasively by LSM at or above 25 kPa alone, or LSM 20 to 24.9 kPa with platelets below 150 x 10^9/L, or LSM 15 to 19.9 kPa with platelets below 110 x 10^9/L. Where spleen stiffness measurement is available, values below 21 kPa argue against CSPH and above 50 kPa argue for it. These non-invasive cutoffs are conditional probability thresholds, not universal diagnostic rules, and hold only when their derivation conditions are met. They were established in compensated advanced chronic liver disease of viral (treated or untreated HBV/HCV), alcohol-related, or non-obese (BMI under 30) MASLD etiology, and are not validated for and should not be applied to cholestatic (e.g. PBC, PSC), vascular, or other etiologies, in which different cutoffs apply. They also require a technically reliable liver stiffness measurement by vibration-controlled transient elastography, fasting, at least 10 valid acquisitions, and an IQR/median ratio below 30 percent, and are confounded by factors that raise liver stiffness independently of fibrosis, including ALT flares or acute hepatitis, extrahepatic cholestasis, hepatic congestion (right heart failure), and recent food intake; Baveno VII recommends confirming an LSM-based rule-in on a repeat measurement obtained on a separate day. The spleen stiffness cutoffs apply only to a dedicated 100 Hz spleen module, carry a higher technical failure rate, are machine-dependent, and are not interchangeable with values obtained using the standard 50 Hz liver probe. Where these population or acquisition conditions are not met, the numeric thresholds do not reliably classify CSPH, and HVPG measurement or endoscopy is required rather than a non-invasive determination. Preserve the gray zone: LSM 15 to 25 kPa without a qualifying platelet count is explicitly indeterminate (roughly 40 to 60 percent of cACLD patients) and calls for HVPG and/or endoscopy rather than assumption in either direction. Once CSPH is established, offer a non-selective beta-blocker, carvedilol preferred at 12.5 mg/day, to lower portal pressure and prevent FIRST decompensation, on the strength of PREDESCI. This is a treat-the-pressure strategy rather than a treat-the-varices one: because a patient already on NSBB for CSPH would not have management changed by the finding, screening endoscopy becomes unnecessary for most such patients. Screening EGD is still indicated where elastography is unavailable, technically difficult, or gives discordant results, and for patients who do not meet non-invasive criteria. Standard beta-blocker contraindications (severe asthma, advanced heart block, bradyarrhythmias) continue to apply. For varices needing treatment managed endoscopically, band ligation is repeated every 2 to 4 weeks until obliteration, with surveillance endoscopy at 6 months and annually thereafter. Gastric/cardiofundal varices are treated with cyanoacrylate injection or EUS-guided coil embolization rather than banding, with hepatology involvement. In acute variceal hemorrhage, consider preemptive (early) TIPS within 24 to 72 hours in high-risk patients: Child-Turcotte-Pugh class B with score above 7 and active bleeding at endoscopy despite vasoactive therapy, or CTP class C with score 10 to 13. Keep the document's own qualifier: there is no established universal MELD or CTP cutoff at which TIPS is mandatory, and the decision is case-by-case with hepatology consultation. Statin use in compensated cirrhosis is NOT a recommendation traceable to this document; the current entry's statin sentence needs its own source or removal. Verification note: the Hepatology full text is paywalled (402/403 on direct fetch). Document identity, title, year, volume, pages and authorship were confirmed via Crossref and PubMed metadata; the numeric thresholds above were corroborated from two independent peer-reviewed commentaries on this specific guidance and match the Baveno VII rule-of-five, but were not read verbatim from the primary PDF. A human should confirm the exact guidance-statement wording against the full text before this entry is treated as quotation-grade.

Can Non-Invasive Test Dynamics Serve as Surrogate Endpoints for Histological Improvement in MASH? A Systematic Review and Bayesian Meta-Analysis.

New evidenceMASLDbiomarkersystematic reviewmeta-analysis
Clinical takeawayWhen interpreting MASH drug trial results or enrolling patients in trials, understand that non-invasive test improvements correlate imperfectly with histological improvement and trials likely still require biopsy endpoints rather than relying on LSM, LFC, FIB-4, or ELF alone. No change to clinical management of individual MASH patients outside trials.
What it foundLFC showed probable moderate trial-level surrogacy (R² 62%, 95% CrI 10-95%) for MASH resolution without fibrosis worsening; LSM and LFC were associated with histological outcomes at outcome-level analysis: LSM with OR 2.67 per 30% decrease for fibrosis improvement without MASH worsening (F4-excluded) and OR 2.46 per 30% decrease for MASH resolution without fibrosis worsening; LFC with OR 1.92 per 30% decrease for MASH resolution without fibrosis worsening. However, trial-level surrogacy was limited and imprecise across most non-invasive tests.
ContextBiopsies are the current trial gold standard for assessing MASH response but are invasive and costly. This meta-analysis tests whether non-invasive tests could replace biopsy in future trials. The finding-limited and imprecise surrogacy-suggests that trials cannot yet move to NIT-only endpoints without risking missed drug efficacy or safety signals detectable only on histology.

For adults with MASH and F2-F3 fibrosis identified by non-invasive tests (VCTE 8-15 kPa, MRE 3.1-4.4 kPa, or ELF 9.2-10.5) rather than biopsy, AASLD now gives dedicated, updated practice guidance on both FDA-approved pharmacotherapies: resmetirom (Oct 2024 update) and semaglutide 2.4mg/week subcutaneous (Nov 2025 update, following August 2025 accelerated FDA approval based on ESSENCE trial data: 62.9% vs 34.3% MASH resolution without fibrosis worsening; 36.8% vs 22.4% ≥1-stage fibrosis improvement).

Our full summary of this standard

Diagnose MASLD by hepatic steatosis on imaging (or biopsy) plus at least one cardiometabolic criterion and exclusion of competing etiologies (significant alcohol use, other liver disease), then risk-stratify fibrosis using a sequential non-invasive approach: FIB-4 first, followed by a second-line imaging-based test (VCTE, MRE, or ELF) for indeterminate/high-risk FIB-4, with liver biopsy reserved for discordant or unclear cases. Lifestyle modification (≥7-10% weight loss, Mediterranean diet, exercise) remains the foundation for all patients. For adults with MASH and F2-F3 fibrosis identified by non-invasive tests (VCTE 8-15 kPa, MRE 3.1-4.4 kPa, or ELF 9.2-10.5) rather than biopsy, AASLD now gives dedicated, updated practice guidance on both FDA-approved pharmacotherapies: resmetirom (Oct 2024 update) and semaglutide 2.4mg/week subcutaneous (Nov 2025 update, following August 2025 accelerated FDA approval based on ESSENCE trial data: 62.9% vs 34.3% MASH resolution without fibrosis worsening; 36.8% vs 22.4% ≥1-stage fibrosis improvement). Pioglitazone or vitamin E remain options per the 2023 base guidance. Manage cardiometabolic risk with statins for ASCVD reduction plus glycemic and blood-pressure control; for semaglutide specifically, routine hepatic panels are recommended only as clinically indicated (no discontinuations for LFT elevation in ESSENCE), with monitoring for GI adverse effects and rare risks (AKI, gallbladder disease, pancreatitis, thyroid C-cell tumors, retinopathy progression, lean mass loss). HCC surveillance with ultrasound and AFP every 6 months remains indicated only if cirrhosis is present.

NCACC maps cross-sample spatial niches and reveals cIgG(+) epithelial rare cells driving liver cancer invasion.

Basic sciencehepatocellular carcinomabasic sciencetranslationalbiomarker
Clinical takeawayNo clinical action yet: mechanistic finding in organoid models. Two candidate compounds (nordihydroguaiaretic acid, gallic aldehyde) were identified by virtual screening and validated in patient-derived organoids but have not been tested in humans.
What it foundNCACC framework identified rare cIgG(+) epithelial cells enriched at tumor-invasive fronts with enhanced proliferative and invasive characteristics, associated with disease progression, sustained by STAT1-dependent JAK-STAT signaling.
ContextIn liver cancer, spatial transcriptomics enables detection of rare low-abundance malignant cell populations previously missed by conventional single-cell analysis. Extends known JAK-STAT involvement in cancer to a specific rare epithelial cell population at the invasive front, opening a potential therapeutic direction, but remains mechanistic.

CPS1: a multipurpose mitochondrial enzyme, bile protein, acute liver injury biomarker, and cytokine.

Basic scienceacute liver failurebiomarkerbasic sciencetranslational
Clinical takeawaySerum CPS1 is an emerging biomarker in acetaminophen-related acute liver failure; however, this review does not address whether testing is commercially available or how CPS1 results compare to or improve upon established ALF prognostic criteria (King's College Criteria, INR, lactate). Specific management actions triggered by CPS1 elevation are not defined. CPS1 deficiency is a rare genetic disease managed by metabolic specialists. Cancer roles are mechanistic; no clinical recommendations for cancer management follow from this review.
What it foundCPS1 is a mitochondrial enzyme normally absent from serum; it is selectively released and readily detectable during acute liver failure with a 1-2 hour half-life, positioning it as an emerging prognostic indicator. CPS1 genetic deficiency causes neonatal hyperammonemia and encephalopathy. CPS1 has mechanistic roles in cancer via metabolic reprogramming and immune modulation.
ContextCPS1 has been understood primarily as a urea-cycle enzyme; this review integrates emerging understanding of its roles as a liver-injury biomarker, immune modulator, and potential cancer target, expanding its relevance beyond genetic disease diagnosis.

Orchestrated cell death pathways in cholangiopathies.

Basic sciencebasic sciencetranslational
Clinical takeawayNo clinical action yet: mechanistic review synthesizing cell death pathways. Current therapies bypass these mechanisms; human evidence for targeting them is pending.
What it foundCholangiopathies involve multiple regulated cell death pathways (apoptosis, necroptosis, pyroptosis, ferroptosis, autophagy-dependent) that intersect and form integrated programs (PANoptosis); sublethal activation of these pathways perpetuates cholangiocyte dysfunction independently of overt cell death.
ContextStandard therapies (ursodeoxycholic acid, PPAR agonists) improve biochemical markers but do not directly modify cell death mechanisms. This review synthesizes evidence that multiple intersecting death pathways drive progressive cholangiocyte loss and fibrosis, providing mechanistic rationale for targeted intervention research.

Decision at stakewhether to incorporate cell-death-pathway targeting into cholangiopathy management strategy

Treat with first-line ursodeoxycholic acid (UDCA) 13-15 mg/kg/d divided, and assess biochemical response at 12 months using Paris-II plus continuous risk scores (Globe, UK-PBC). Escalate to a second-line agent (obeticholic acid [contraindicated in cirrhosis with portal hypertension or prior decompensation], seladelpar, elafibranor, or a fibrate) when response is inadequate, guided by a Child-Pugh/portal-hypertension hard gate, and manage pruritus with a stepwise ladder (cholestyramine → rifampin → sertraline → naltrexone). Refer for transplant evaluation for decompensation, refractory pruritus, or rising bilirubin.
