Hepatology, in full.

In adults with cirrhosis, diagnose hepatic encephalopathy (HE) clinically: an alteration in mental status graded by the West Haven criteria (minimal + grade 1 = covert; grades 2-4 = overt, e.g. disorientation, asterixis, somnolence to coma) in a patient with liver disease/portosystemic shunting, made only after excluding other causes of altered mentation (structural, infectious, metabolic, toxic). Use the operational classification (type, time course [episodic/recurrent/persistent], and precipitated vs spontaneous). Measure blood ammonia primarily as a RULE-OUT test: a NORMAL ammonia level questions the diagnosis of HE (high negative predictive value), but ammonia does NOT add diagnostic, staging or prognostic value in a patient with known HE and should not be used to grade HE or to titrate therapy; sample and handle it correctly (prompt, on ice). In every patient with overt HE, actively search for and treat a precipitating factor, infection, GI bleeding, dehydration/diuretic overuse, electrolyte disturbance, constipation, sedatives/psychoactive drugs. Treat an episode of overt HE with a non-absorbable disaccharide (lactulose) titrated to 2-3 soft bowel movements per day (oral, or by enema in grade 3-4 to avoid aspiration); polyethylene glycol may be substituted for a lactulose enema in patients with persistent constipation, sub-ileus, or intolerance to lactulose, and although small single-centre trials suggest more rapid resolution of HE, the evidence is limited and whether it should replace or be combined with lactulose is unclear, so it is not an established faster-acting alternative or adjunct. After a first episode of overt HE, give lactulose as secondary prophylaxis (titrated to 2-3 BM/day); add rifaximin 550 mg twice daily as an ADJUNCT to lactulose only after >=1 further episode of overt HE occurs within 6 months of the first (or continue rifaximin already in use). Do not restrict dietary protein: target the general cirrhosis nutrition goals (protein 1.2-1.5 g/kg/day, energy ~35 kcal/kg/day) with meals distributed across the day and a late-evening snack; in recurrent/persistent HE, substitution of animal protein with vegetable and dairy protein can be considered provided total protein intake is not compromised. For HE refractory to lactulose + rifaximin, reconsider the diagnosis and re-search for a missed precipitant or a large spontaneous portosystemic shunt; obliteration of an accessible portosystemic shunt can be considered in stable patients with preserved liver function (MELD <11), and post-TIPS HE refractory to medical therapy may warrant TIPS reduction/occlusion. Evaluate for liver transplantation in eligible patients, refer for transplant assessment in patients with recurrent/persistent HE (and hepatic myelopathy as soon as possible), recognizing that a first episode of overt HE already carries a poor prognosis.

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.

Manage diabetes in GI/hepatology patients by individualizing the A1c target to the population, in cirrhosis, A1c is unreliable because altered red blood cell turnover typically underestimates glycemia, so set glycemic goals using blood glucose monitoring and/or CGM rather than a fixed A1c cutoff, and in diabetic gastroparesis individualize the target rather than applying a universal cutoff; ≤7% pre-bariatric, <6.5% pre-conception, while screening all T2DM for MASLD with FIB-4, screening T1DM for concurrent celiac disease, and screening for diabetic gastroparesis when chronic nausea, early satiety, or postprandial fullness are present. Evaluate new-onset DM after age 50 without obesity for a pancreatic cancer differential, and coordinate peri-procedural medication holds and multidisciplinary endocrinology involvement.

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.

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.

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.

Per the ACG 2017 abstract and the 'Elevation of Total Bilirubin Level' section (summary statements + Figure 5 + Table 6): Elevated total serum bilirubin (normal usually <1.1 mg/dl) should be FRACTIONATED into conjugated (direct) and unconjugated (indirect) fractions; fractionation is most helpful when ALT/AST and alkaline phosphatase are normal or near-normal. An elevated serum conjugated (direct) bilirubin implies hepatocellular disease or biliary obstruction IN MOST SETTINGS, in contrast to unconjugated (which is over-production/hemolysis, decreased uptake, or decreased conjugation), the guideline keeps 'in most settings' rather than stating an absolute rule. PREDOMINANT-UNCONJUGATED elevation (Fig 5, left arm): history/exam, assess transaminases and ALP, review medications, evaluate for hemolysis (haptoglobin, reticulocytes, LDH) and for Gilbert's syndrome; in an asymptomatic person with mild unconjugated hyperbilirubinemia (<4 mg/dl) with normal transaminases/ALP, no hemolysis, and no offending drug, a presumptive Gilbert's diagnosis can be made and further evaluation is not routinely necessary (Gilbert's: total almost never >6 mg/dl, usually <3; fasting/illness raises it 2-3 fold). Optional UGT1A1 genotype and workup of uncommon Table-6 causes only if persistently unexplained. PREDOMINANT-CONJUGATED elevation (Fig 5, right arm): history/exam, assess transaminases and ALP, review medications, evaluate clinically overt etiologies (sepsis, TPN, cirrhosis, biliary obstruction), and perform right-upper-quadrant ultrasound, if ductal dilatation → ERCP or MRCP; if no ductal dilatation → check AMA, ANA and SMA. Per graded Recommendations 14-15, alkaline phosphatase elevation with or without bilirubin warrants anti-mitochondrial antibody for PBC and MR cholangiography or ERCP in conjunction with IgG4 for PSC (both Strong recommendation, very low quality). Consider liver biopsy for diagnostic confirmation when the elevation is otherwise unexplained, symptomatic, worsening over time, or associated with abnormal transaminases. Two rare BENIGN inherited conjugated hyperbilirubinemias, Dubin-Johnson and Rotor, show direct bilirubin ~50% of total with all other liver tests normal including ALP and GGT; it is not necessary to distinguish them. Conjugated total bilirubin may exceed 30 mg/dl in severe liver damage (e.g., alcoholic hepatitis with cirrhosis, or advanced cirrhosis with sepsis/renal failure), and an isolated conjugated hyperbilirubinemia may follow major surgery and typically resolves.

Per the 2024 ADQI-ICA joint consensus (which updates the 2015 ICA-AKI criteria referenced in AASLD 2021), in a patient with cirrhosis and ascites: DIAGNOSE HRS-AKI when all of (a) cirrhosis with ascites; (b) AKI by KDIGO/ICA criteria, serum creatinine rise ≥0.3 mg/dL (26.5 µmol/L) within 48h or ≥50% from a baseline known or presumed within the prior 7 days, and/or urine output ≤0.5 mL/kg/h for ≥6h (strong recommendation, grade A); (c) absence of improvement in serum creatinine and/or urine output within 24h following adequate volume resuscitation WHEN CLINICALLY INDICATED, the consensus recommends AGAINST systematic 48h albumin administration as a diagnostic requisite (strong recommendation, grade D), and only where volume status is equivocal is a single fluid challenge (250-500 mL crystalloid, or 1-1.5 g/kg of 20-25% albumin) assessed within 24h; and (d) absence of strong evidence for an alternative primary cause of AKI (e.g., septic shock requiring vasopressors, acute glomerular injury, obstruction, or nephrotoxin-induced AKI) (not graded). HRS-AKI is a phenotype specific to advanced cirrhosis and ascites: coexisting CKD, tubular injury or proteinuria do NOT exclude it, and it may coexist with, or be superimposed on, other AKI etiologies rather than requiring pure exclusion. TREAT: immediately on diagnosis start a vasoconstrictor plus 20-25% albumin (strong recommendation, grade A). Terlipressin is first-line, continuous IV infusion 2-12 mg/day, titrated up by ≥2 mg/day every 24h to a maximum 12 mg/day if serum creatinine has not fallen ≥25%; or IV bolus 1-2 mg every 6h, escalated from 1 mg to 2 mg every 6h on that same ≥25% serum-creatinine response threshold, with the 12 mg/day maximum applying only to continuous infusion and not to bolus dosing. If terlipressin is unavailable or contraindicated, norepinephrine (continuous infusion 0.5-3 mg/h, up-titrated 0.5 mg/h every 4h to raise MAP ≥10 mmHg; requires ICU care and a central line) may be more appropriate. Midodrine 7.5-15 mg PO every 8h plus octreotide 100-200 µg SC every 8h with albumin is third-line, considered only if terlipressin is contraindicated AND transfer to ICU for norepinephrine is not possible. Give 20-25% albumin 20-40 g/day with any vasoconstrictor, adjusted daily to volume status and withheld for fluid overload/pulmonary edema. Discontinue vasoconstrictors when serum creatinine returns to within 0.3 mg/dL of baseline, for a severe adverse reaction, if kidney function does not improve after 48h at maximum tolerated dose, if RRT is indicated, or at a maximum of 14 days of therapy (strong recommendation, grade B). Initiation of RRT should be individualized to clinical context and anticipated or observed life-threatening AKI-related complications (best-practice statement) rather than framed strictly as a transplant-bridge measure. Recommend expedited evaluation for liver transplantation following an episode of AKI (best-practice statement); LT in selected patients is the definitive treatment for HRS-AKI regardless of vasoconstrictor response (strong recommendation, grade A), with vasoconstrictors serving as a bridge to transplantation or renal recovery rather than a cure.

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.

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.

When LFT abnormalities (either cholestatic-pattern with relatively spared transaminases or acute hepatocellular injury) occur alongside elevated right-sided filling pressures, pericardial disease, or systemic congestion, pursue cardiac workup (echocardiogram, BNP/NT-proBNP, hepatic venous Doppler, cardiac MRI or right heart catheterization if equivocal) and treat the underlying cardiac/pericardial driver, pericardiectomy for constriction, volume management for right heart failure, valve surgery for severe TR, HF GDMT. Defer the cirrhosis SOC pathway (NSBB initiation, HCC screen intensification, transplant workup) until cardiac evaluation completes, since congestion-driven liver findings often improve with treatment of the cardiac cause and elastography is falsely elevated in a congested liver. Monitor LFTs during diuresis and reserve liver biopsy for cases where etiology remains unclear after cardiac workup.
