Incidental hepatic steatosis
It is important to identify patients at risk of progressive fibrosis.
Calculation of the fibrosis-4 (FIB-4) score (based on age, alanine and aspartate aminotransferase [ALT and AST] levels, and platelet count by the primary care provider, using either an online calculator or the dot phrase “.fib4” in Epic) is a useful first step. If the value is low (with a high negative predictive value for advanced fibrosis), the patient does not need to be referred but can be managed for risk factors for nonalcoholic fatty liver disease. If the value is high, suggesting advanced fibrosis, the patient requires further evaluation. If the value is indeterminate, options for assessing liver stiffness include vibration-controlled transient elastography (with a controlled attenuation parameter to assess the degree of steatosis) and ultrasound elastography. A low liver stiffness score argues against the need for subspecialty management. An indeterminate score may be followed by magnetic resonance elastography, if available. An alternative to elastography is the enhanced liver fibrosis (ELF) blood test, based on serum levels of tissue inhibitor of metalloproteinases 1 (TIMP-1), amino-terminal propeptide of type III procollagen (PIIINP), and hyaluronic acid.

FROM GASTRO HEP ADVANCES
Liver disease gets new name and diagnostic criteria
Nonalcoholic fatty liver disease will now be called metabolic dysfunction–associated steatotic liver disease, or MASLD, according to new nomenclature adopted by a global consensus panel composed mostly of hepatology researchers and clinicians.
The new nomenclature, published in the journal Hepatology, includes the umbrella term steatotic liver disease, or SLD, which will cover MASLD and MetALD, a term describing people with MASLD who consume more than 140 grams of alcohol per week for women and 210 grams per week for men.
Metabolic dysfunction–associated steatohepatitis, or MASH, will replace the term nonalcoholic steatohepatitis, or NASH.
Mary E. Rinella, MD, of University of Chicago Medicine led the consensus group. The changes were needed, Dr. Rinella and her colleagues argued, because the terms “fatty liver disease” “and nonalcoholic” could be considered to confer stigma, and to better reflect the metabolic dysfunction occurring in the disease. Under the new nomenclature, people with MASLD must have a cardiometabolic risk factor, such as type 2 diabetes. People without metabolic parameters and no known cause will be classed as having cryptogenic SLD.
While the new nomenclature largely conserves existing disease definitions, it allows for alcohol consumption beyond current parameters for nonalcoholic forms of the disease. “There are individuals with risk factors for NAFLD, such as type 2 diabetes, who consume more alcohol than the relatively strict thresholds used to define the nonalcoholic nature of the disease [and] are excluded from trials and consideration for treatments,” the authors wrote.
Moreover, they wrote, “within MetALD there is a continuum where conceptually the condition can be seen to be MASLD or ALD predominant. This may vary over time within a given individual.”
Respondents overwhelmingly agreed, however, that even moderate alcohol use alters the natural history of the disease and that patients with more than minimal alcohol consumption should be analyzed separately in clinical trials.
The new nomenclature reflects a 3-year effort involving some 236 panelists from 56 countries who participated in several rounds of online surveys using a Delphi process. Pediatricians, gastroenterologists, and endocrinologists also participated as well as some patient advocates. Changes were based on a super-majority of opinion (67% or higher), though the consensus on whether the term “fatty” was stigmatizing never reached that threshold. In early rounds of surveys only 44% of respondents considered the word “fatty” to be stigmatizing, while more considered “nonalcoholic” to be problematic.
“Substantial proportions of the respondents deemed terms such as ‘fatty’ stigmatizing, hence its exclusion as part of any new name,” Dr. Rinella and her colleagues wrote. “Although health care professionals may contend that patients have not reported this previously, this likely reflects in part a failure to ask the question in the first place and the power imbalance in the doctor-patient relationship.” The authors noted that the new terminology may help raise awareness at a time when new therapeutics are in sight and it becomes more important to identify at-risk individuals.
Of concern was whether the new definitions would alter the utility of earlier data from registries and trials. However, the authors determined that some 98% of people registered in a European NAFLD cohort would meet the new criteria for MASLD. “Maintenance of the term, and clinical definition, of steatohepatitis ensures retention and validity of prior data from clinical trials and biomarker discovery studies of patients with NASH to be generalizable to individuals classified as MASLD or MASH under the new nomenclature, without impeding the efficiency of research,” they stated.
The effort was spearheaded by three international liver societies: La Asociación Latinoamericana para el Estudio del Hígado, the American Association for the Study of Liver Diseases, and the European Association for the Study of the Liver, as well as the cochairs of the NAFLD Nomenclature Initiative.
Each of the authors disclosed a number of potential conflicts of interest.

FROM HEPATOLOGY
Breakthroughs and challenges in hepatology
CHICAGO – The most notable is the progress from discovery of the hepatitis C virus (previously non-A, non-B hepatitis) in 1989 to a near 100% cure with 8-12 weeks of oral medications in just 30 years, culminating in the The Nobel Prize in Physiology or Medicine in 2020.
This remarkable feat is matched by the progress from discovery of the hepatitis B virus (initially coined Australia antigen) and a 1976 Nobel Prize to an effective vaccine in 1981, to a list of antiviral drugs approved beginning in 1992 (with currently available nucleos(t)ide analogues associated with near zero risk of antiviral drug resistance even when used as monotherapy), to demonstration that both hepatitis B vaccine and antivirals can prevent liver cancer. Other major breakthroughs include blood-based and image-based noninvasive assessment of liver fibrosis obviating the need for liver biopsy to stage liver disease, and multiple systemic therapies for advanced liver cancer.
However, there remain many challenges. While we have the tools to eliminate hepatitis B and hepatitis C, resources and coordinated efforts are needed to realize this feasible goal. Development of a vaccine for hepatitis C and a cure for hepatitis B will facilitate this goal.
The biggest present-day challenges in hepatology are the epidemics of nonalcoholic fatty liver disease (NAFLD) and alcohol-associated liver disease (ALD), particularly since both are increasingly impacting young people, socially disadvantaged populations, and those with mental health problems. Social isolation and mental and financial stressors associated with the COVID pandemic have aggravated both NAFLD and ALD, which have now become the leading indications for liver transplantation. Multi-pronged approaches, including public policies and education, destigmatization, easy access to mental health care, provider training, and provision of multi-disciplinary care, are needed to curb this tsunami. NAFLD affects more than 30% of the global population, and screening with simple biomarker(s) followed by liver stiffness measurement using elastography has been proposed to identify patients with or at high risk of advanced fibrosis or cirrhosis for specialist care. NAFLD is a heterogeneous disease and the requirement for paired liver biopsies to demonstrate benefit have made drug development challenging. Better phenotyping of disease and surrogates for outcomes are needed. Liver cancer is one of the top cancer killers globally, but it is also a preventable cancer making prevention and early treatment of liver disease a top public health priority.

AT DDW 2023
FDA rejects NASH drug for the second time
In response, the company has decided to discontinue all NASH-related investment.
Intercept first sought FDA approval for OCA in treatment of NASH in 2019 and received a complete response letter. The company refiled for a new drug application in December 2022. A second resubmission would require a completion of the long-term outcomes phase of an ongoing clinical trial, according to an Intercept press release.
The FDA decision follows the recommendation from May’s FDA Gastrointestinal Drugs Advisory Committee meeting. During the meeting, members voted 15 to 1 to advise deferring approval until clinical outcome data became available. Intercept’s clinical trial data demonstrated that OCA showed moderate benefit over placebo in improving fibrosis in NASH patients, but “there is uncertainty how the magnitude of changes in these surrogate endpoints may translate to meaningful changes in clinical outcomes,” an FDA meeting briefing document stated. There were also notable safety concerns including an increased risk for drug-induced liver injury.
An estimated 16.8 million Americans have NASH, and there are no FDA-approved medications for the condition.
Intercept plans to promptly begin closing out their NASH clinical trial and restructuring to focus on rare and serious liver diseases.
“While this is clearly not the outcome that we have worked toward, I’m proud of the impact that Intercept has made to move the science of NASH forward and bring the field closer to a treatment option,” said Jerry Durso, the president and CEO of Intercept, in a statement. “Intercept thanks the scientists, clinicians, and patients whose contributions to the clinical development of OCA in NASH have significantly advanced the understanding of this deadly disease.”

‘Exciting time for NASH’ with resmetirom phase 3 results
VIENNA – Resolution of nonalcoholic steatohepatitis (NASH), and reduction of fibrosis on liver biopsy were achieved with the oral, thyroid hormone receptor beta-selective agonist resmetirom (Madrigal Pharmaceuticals) in patients with NASH and associated cirrhosis in a pivotal phase 3 clinical trial. The primary results of the MAESTRO-NASH (NCT03900429) trial were reported at the European Association for the Study of the Liver Congress 2023.
Both doses of resmetirom – 80 mg and 100 mg – met the primary endpoints of NASH resolution and no worsening of fibrosis on liver biopsy. The key secondary endpoint of LDL cholesterol lowering was also achieved with statistical significance. Likewise, improvement was seen in liver enzymes, and liver and spleen volumes.
In the intent-to-treat population, NASH resolution was achieved in 26% (P < .0001) in the 80-mg resmetirom group, 30% (P < .0001) in the 100-mg group, and 10% in those taking placebo. And ≥ 1-stage improvement in fibrosis with no worsening of the nonalcoholic fatty liver disease activity score (NAS) was achieved by 24% (P < .0002), 26% (P < .0001), and 14% in these groups respectively.
The investigational, liver-directed agent, designed to improve NASH by increasing hepatic fat metabolism and reducing lipotoxicity, was well tolerated overall with a favorable safety profile.
“This is an exciting time for NASH because we are at the forefront of having a drug to treat these patients, and the benefit to patients promises to be huge,” asserted Stephen Harrison, MD, principal investigator of the MAESTRO studies, gastroenterologist and hepatologist, and founder of Pinnacle Clinical Research, San Antonio, in reporting 52-week results.
“This is the first treatment to achieve meaningful effects on both primary liver biopsy endpoints – disease activity and fibrosis – which is absolutely critical because fibrosis pertains to a worse prognosis. [These results] are reasonably likely to predict clinical benefit in a phase 3 trial in patients with NASH,” he added.
FDA-chosen endpoints likely to predict clinical outcomes
The ongoing 54-month, phase 3, registrational, double-blind, placebo-controlled trial involved taking liver biopsies from 966 patients at around 200 global sites. Biopsy readings were taken by two pathologists that were then combined into a single treatment effect.
Patients had biopsy-proven NASH with fibrosis stages F1B, F2, or F3, the presence of three or more metabolic risk factors, a FibroScan vibration-controlled transient elastography (VCTE) score of 8.5 kPa or more, baseline MRI proton density fat fraction (MRI-PDFF) of 8% or more, and a NAS score of 4 or more with at least 1 in each NAS component. Around 65% of participants had type 2 diabetes, between 13% and 16% were taking glucagonlike peptide-1 (GLP-1) receptor agonists, and 46%-51% were taking statins.
Patients were randomized 1:1:1 to once-daily resmetirom 80 mg or 100 mg orally or to placebo and treated for 52 weeks.
Both liver histological improvement primary endpoints at week-52 were proposed by the U.S. Food and Drug Administration as reasonably likely to predict clinical benefit and as such support accelerated approval for the treatment of NASH with liver fibrosis. These primary endpoints were NASH resolution (ballooning 0, inflammation 0/1) with ≥ 2-point improvement in NAS with no worsening of fibrosis, and ≥ 1-stage reduction in fibrosis with no worsening of NAS.
Patients on resmetirom showed improvement in NAS components and fibrosis, and less worsening of NAS and fibrosis, compared with placebo. Percentage improvement was seen in 31%, 33%, and 15% of patients on 80 mg resmetirom, 100 mg resmetirom, and placebo respectively; no change was seen in 51%, 48%, and 51% respectively; and worsening was seen in 18%, 19%, and 34% respectively.
The key secondary endpoint of LDL cholesterol lowering was also met. “There was a significant effect of resmetirom 80 and 100 mg on multiple atherogenic lipids/lipoproteins at both week 24 and 52,” reported Dr. Harrison. The 52-week percentage change from baseline in LDL cholesterol was –14%, –20%, and 0% for the 80-mg resmetirom group, the 100-mg group, and the placebo group respectively.
“We also saw a significant reduction in liver enzymes [alanine transaminase, aspartate transaminase, and gamma-glutamyl transferase (GGT)] relative to placebo both in terms of percentage and absolute measures,” Dr. Harrison added. “[And] the change in liver enzymes was associated with the neutral biomarker that increases with resmetirom target engagement.”
Resmetirom at both doses also resulted in a significant effect on MRI-PDFF and Fibroscan CAP. At week 52, 80 mg resmetirom, 100 mg, and placebo led to –42.1%, –51.4% and –10.4% change from baseline in MRI-PDFF, while Fibroscan CAP changed by –39.6%, –41.3%, and –14.5% respectively, reported Dr. Harrison. Liver volume dropped by –21.6% in the 80-mg group and –25.8% in the 100-mg group, compared with –1.0% in the placebo group. Spleen volume changed by –5.9%, –6.1%, and +3.2% respectively.
Liver stiffness, as measured by Fibroscan VCTE at week 52, changed from –3.7 KPa (F1B) to –2.0 KPa (F3) at 80 mg, and from –3.7 KPa (F1B) to –2.5 KPa (F2) and –3.3 KPa (F3) at the 100-mg dose.
Further analysis showed that improvements in fibrosis and NASH resolution were seen across all key subgroups, including baseline fibrosis stage (F2 or F3), NAS (< 6, ≥ 6), type 2 diabetes status, age (< 65 years, ≥ 65 years), and sex.
Safety profile
“The safety profile of resmetirom in the MAESTRO-NASH trial is consistent with previous phase 2/3 trials in which the most common adverse events were diarrhea and nausea at treatment initiation,” said Dr. Harrison.
Study discontinuations in the 100-mg group were increased relative to placebo during the first few weeks of treatment and were similar in all treatment groups up to 52 weeks. Discontinuations of patients on resmetirom 100 mg were mainly gastrointestinal related.
Phase 2 results of the serial liver biopsy trial in adults with biopsy-confirmed NASH showed that resmetirom resolved NASH in a significantly greater percentage of patients and reduced liver enzymes, inflammatory biomarkers, and fibrosis, compared with placebo.
“We’ve been waiting for a long, long time for a therapy for these patients because until now, they have been challenged with lifestyle modifications to lose and maintain weight,” said Dr. Harrison. “There’s been a delay in identifying patients with this disease because we’ve had no treatment, but now that we are on the forefront of a treatment, it allows clinicians to open their minds to the possibility of identifying these patients.”
Dr. Harrison noted that a limitation of these data was the lack of clinical outcomes data to correlate with the biopsy data; however, the MAESTRO-NASH trial will continue to 54 months to accrue and evaluate clinical outcomes.
Milan Mishkovikj, MSc, board director of the European Liver Patients Association, Bitola, North Macedonia, commented on the potential benefit of this drug for patients. “Adhering to a healthy lifestyle is not always easy – not in all countries – so it’s encouraging to have a drug that hopefully is affordable and accessible to us. Now we need to manage the expectations of patients and caregivers.”
EASL’s vice secretary Aleksander Krag, MD, PhD, professor and head of hepatology at University of Southern Denmark, Odense, and Odense University Hospital remarked, “This is so exciting. This phase 3 trial is a real game-changer in the field of fatty liver disease because it has nearly 1,000 patients over 52 weeks of treatment.”
Madrigal Pharmaceuticals plans to submit an application to the FDA by end of the second quarter with a priority review.

VIENNA – Resolution of nonalcoholic steatohepatitis (NASH), and reduction of fibrosis on liver biopsy were achieved with the oral, thyroid hormone receptor beta-selective agonist resmetirom (Madrigal Pharmaceuticals) in patients with NASH and associated cirrhosis in a pivotal phase 3 clinical trial. The primary results of the MAESTRO-NASH (NCT03900429) trial were reported at the European Association for the Study of the Liver Congress 2023.
Both doses of resmetirom – 80 mg and 100 mg – met the primary endpoints of NASH resolution and no worsening of fibrosis on liver biopsy. The key secondary endpoint of LDL cholesterol lowering was also achieved with statistical significance. Likewise, improvement was seen in liver enzymes, and liver and spleen volumes.
In the intent-to-treat population, NASH resolution was achieved in 26% (P < .0001) in the 80-mg resmetirom group, 30% (P < .0001) in the 100-mg group, and 10% in those taking placebo. And ≥ 1-stage improvement in fibrosis with no worsening of the nonalcoholic fatty liver disease activity score (NAS) was achieved by 24% (P < .0002), 26% (P < .0001), and 14% in these groups respectively.
The investigational, liver-directed agent, designed to improve NASH by increasing hepatic fat metabolism and reducing lipotoxicity, was well tolerated overall with a favorable safety profile.
“This is an exciting time for NASH because we are at the forefront of having a drug to treat these patients, and the benefit to patients promises to be huge,” asserted Stephen Harrison, MD, principal investigator of the MAESTRO studies, gastroenterologist and hepatologist, and founder of Pinnacle Clinical Research, San Antonio, in reporting 52-week results.
“This is the first treatment to achieve meaningful effects on both primary liver biopsy endpoints – disease activity and fibrosis – which is absolutely critical because fibrosis pertains to a worse prognosis. [These results] are reasonably likely to predict clinical benefit in a phase 3 trial in patients with NASH,” he added.
FDA-chosen endpoints likely to predict clinical outcomes
The ongoing 54-month, phase 3, registrational, double-blind, placebo-controlled trial involved taking liver biopsies from 966 patients at around 200 global sites. Biopsy readings were taken by two pathologists that were then combined into a single treatment effect.
Patients had biopsy-proven NASH with fibrosis stages F1B, F2, or F3, the presence of three or more metabolic risk factors, a FibroScan vibration-controlled transient elastography (VCTE) score of 8.5 kPa or more, baseline MRI proton density fat fraction (MRI-PDFF) of 8% or more, and a NAS score of 4 or more with at least 1 in each NAS component. Around 65% of participants had type 2 diabetes, between 13% and 16% were taking glucagonlike peptide-1 (GLP-1) receptor agonists, and 46%-51% were taking statins.
Patients were randomized 1:1:1 to once-daily resmetirom 80 mg or 100 mg orally or to placebo and treated for 52 weeks.
Both liver histological improvement primary endpoints at week-52 were proposed by the U.S. Food and Drug Administration as reasonably likely to predict clinical benefit and as such support accelerated approval for the treatment of NASH with liver fibrosis. These primary endpoints were NASH resolution (ballooning 0, inflammation 0/1) with ≥ 2-point improvement in NAS with no worsening of fibrosis, and ≥ 1-stage reduction in fibrosis with no worsening of NAS.
Patients on resmetirom showed improvement in NAS components and fibrosis, and less worsening of NAS and fibrosis, compared with placebo. Percentage improvement was seen in 31%, 33%, and 15% of patients on 80 mg resmetirom, 100 mg resmetirom, and placebo respectively; no change was seen in 51%, 48%, and 51% respectively; and worsening was seen in 18%, 19%, and 34% respectively.
The key secondary endpoint of LDL cholesterol lowering was also met. “There was a significant effect of resmetirom 80 and 100 mg on multiple atherogenic lipids/lipoproteins at both week 24 and 52,” reported Dr. Harrison. The 52-week percentage change from baseline in LDL cholesterol was –14%, –20%, and 0% for the 80-mg resmetirom group, the 100-mg group, and the placebo group respectively.
“We also saw a significant reduction in liver enzymes [alanine transaminase, aspartate transaminase, and gamma-glutamyl transferase (GGT)] relative to placebo both in terms of percentage and absolute measures,” Dr. Harrison added. “[And] the change in liver enzymes was associated with the neutral biomarker that increases with resmetirom target engagement.”

What is new in hepatology in 2023?
CHICAGO – Two landmark phase 2 trials of the glucagon-like peptide 1 (GLP-1) receptor agonist, semaglutide, Food and Drug Administration–approved for type 2 diabetes or obesity, demonstrated improvements in nonalcoholic steatohepatitis (NASH) activity and resolution in stage 2 or 3 fibrosis (F2/F3), but not F4 fibrosis.1,2 The first randomized trial to compare the efficacy and safety of bariatric surgery with lifestyle intervention plus best medical care for histologically confirmed NASH demonstrated the superiority of bariatric surgery.3
There has been a paradigm shift in risk stratification of cirrhosis and targets for prevention and treatment of decompensation. A newer term, advanced chronic liver disease (ACLD), represents a shift away from needing a histologic or radiologic diagnosis of cirrhosis while reduction in portal pressure is a therapeutic goal. Evidence supports noninvasive liver stiffness measurement (LSM) using transient elastography to identify those with clinically significant portal hypertension (CSPH) (e.g., hepatic venous pressure gradient ≥ 10 mm Hg) who may benefit from therapy to lower portal pressure. Accordingly, based on landmark studies, the American Association for the Study of Liver Diseases (AASLD) recommends early utilization of nonselective beta-blocker therapy, with carvedilol as a preferred agent, in CSPH to decrease the risk of decompensation and mortality.4
The definition of hepatorenal syndrome has also substantially evolved.5 Terminology now acknowledges significant renal impairment at lower creatinine levels than previously used and recognizes the contribution of chronic kidney disease. The FDA approved terlipressin, a potent vasoconstrictor, for the treatment of hepatorenal syndrome with acute kidney injury (HRS-AKI, formerly HRS-Type I).
The AASLD published updates in advanced management of variceal bleeding highlighting intravascular interventions for esophageal, gastric, and ectopic varices. Data support early transjugular intrahepatic portosystemic shunt (TIPS) creation in patients with Child-Turcotte-Pugh (CTP) B or CTP C (< 14 points) within 72 hours of initial bleeding. However, hepatic encephalopathy remains a common complication. A randomized controlled trial demonstrated that rifaximin started 14 days prior to elective TIPS may reduce post-TIPS hepatic encephalopathy by 52%.6
Surveillance and treatment approaches for hepatocellular carcinoma (HCC) continue to evolve as reflected in new AASLD guidance in June 2023. Screening among high-risk patients should include ultrasound and serum alpha-fetoprotein every 6 months and novel screening approaches including imaging and blood-based biomarkers are on the horizon. There also have been significant advances in systemic therapies for HCC. First-line therapy for advanced HCC with CTP A cirrhosis now includes either atezolizumab/bevacizumab or durvalumab/tremelimumab. There is an evolving role for systemic therapy in the adjuvant setting as well, with emerging data supporting checkpoint inhibitors after resection or ablation among patients at high risk of recurrence.
Allocation policies continue to evolve for liver transplantation as waitlist prioritization transitions to MELD 3.0. The new score improves predictive accuracy for short-term mortality and addresses sex disparity in waitlist outcomes by lowering the prioritization of creatinine (and its threshold) and adding albumin to the current MELD-Na formula. MELD 3.0 will be adopted by the United Network for Organ Sharing in July 2023.
It has been a whirlwind 2023 for the liver community and we are excited and hopeful for new breakthroughs to come.

Accordingly, based on landmark studies, the American Association for the Study of Liver Diseases (AASLD) recommends early utilization of nonselective beta-blocker therapy, with carvedilol as a preferred agent, in CSPH to decrease the risk of decompensation and mortality.4
The definition of hepatorenal syndrome has also substantially evolved.5 Terminology now acknowledges significant renal impairment at lower creatinine levels than previously used and recognizes the contribution of chronic kidney disease. The FDA approved terlipressin, a potent vasoconstrictor, for the treatment of hepatorenal syndrome with acute kidney injury (HRS-AKI, formerly HRS-Type I).
The AASLD published updates in advanced management of variceal bleeding highlighting intravascular interventions for esophageal, gastric, and ectopic varices. Data support early transjugular intrahepatic portosystemic shunt (TIPS) creation in patients with Child-Turcotte-Pugh (CTP) B or CTP C (< 14 points) within 72 hours of initial bleeding. However, hepatic encephalopathy remains a common complication. A randomized controlled trial demonstrated that rifaximin started 14 days prior to elective TIPS may reduce post-TIPS hepatic encephalopathy by 52%.6
Surveillance and treatment approaches for hepatocellular carcinoma (HCC) continue to evolve as reflected in new AASLD guidance in June 2023. Screening among high-risk patients should include ultrasound and serum alpha-fetoprotein every 6 months and novel screening approaches including imaging and blood-based biomarkers are on the horizon. There also have been significant advances in systemic therapies for HCC. First-line therapy for advanced HCC with CTP A cirrhosis now includes either atezolizumab/bevacizumab or durvalumab/tremelimumab. There is an evolving role for systemic therapy in the adjuvant setting as well, with emerging data supporting checkpoint inhibitors after resection or ablation among patients at high risk of recurrence.
Allocation policies continue to evolve for liver transplantation as waitlist prioritization transitions to MELD 3.0. The new score improves predictive accuracy for short-term mortality and addresses sex disparity in waitlist outcomes by lowering the prioritization of creatinine (and its threshold) and adding albumin to the current MELD-Na formula. MELD 3.0 will be adopted by the United Network for Organ Sharing in July 2023.
It has been a whirlwind 2023 for the liver community and we are excited and hopeful for new breakthroughs to come.

FDA advisory committee votes against approval for NASH drug
The Food and Drug Administration’s Gastrointestinal Drugs Advisory Committee has voted against the accelerated approval of Intercept Pharmaceuticals’ obeticholic acid (OCA) for treatment of nonalcoholic steatohepatitis (NASH) with stage 2 or 3 fibrosis.
This is the second time that Intercept has sought FDA approval for OCA in treating NASH.
The committee voted 12 to 2 (with 2 abstentions) that the benefits of OCA did not outweigh the risks to this patient population. While OCA showed a modest benefit of improving fibrosis in NASH patients, safety concerns included increased risk for drug-induced liver injury (DILI), cholelithiasis, pruritus, dyslipidemia, and dysglycemia.
Committee members were most concerned with the increased risk for DILI in patients taking OCA. Intercept said that frequent monitoring for DILI in such a large eligible population – an estimated 6-8 million individuals taking the drug to treat the condition – would be difficult.
“Typically, in clinical practice, NASH patients are followed every 6-12 months, so more frequent monitoring would be a substantial change and may not be achievable outside of the clinical trial setting,” according to a briefing document released before the committee meeting.
The FDA estimates that 16.8 million U.S. adults have NASH, with 5.7 million having NASH with advanced fibrosis, according to briefing documents. NASH is the second leading cause of liver transplants in the United States and is the leading cause in women. There are currently no FDA-approved therapies to treat NASH.
OCA, sold under the commercial name Ocaliva, was first approved in 2016 to treat primary biliary cholangitis, and is prescribed at up to 10 mg per day. Intercept proposed that OCA be given in daily 25-mg doses in the treatment of precirrhotic fibrosis attributable to NASH.
In 2019, Intercept initially filed for a new drug application (NDA) for OCA for the treatment of precirrhotic fibrosis attributable to NASH but were issued a Complete Response Letter after the FDA determined that the medication had an “unfavorable risk benefit-risk assessment.” Intercept resubmitted an NDA for OCA in December 2022, including two 18-month analyses from a phase 3 study, REGENERATE (Randomized Global Phase 3 Study to Evaluate the Impact on NASH with Fibrosis of Obeticholic Acid Treatment). In the study, which included data from 931 patients, OCA 25 mg outperformed placebo in improving fibrosis with no worsening of NASH over 18 months, one of two primary endpoints of the clinical trial. The estimated risk difference ranged from 8.6 to 12.8 across different analyses, which the FDA categorized as a “modest treatment effect.”
There was no significant difference between OCA 25 mg and placebo in NASH resolution with no worsening fibrosis. Both endpoints were surrogate endpoints, meaning that they were “reasonably likely to predict clinical benefit.” The FDA noted that it is not known if a decrease in fibrosis stage would lead to clinically meaningful outcomes, such as reduction in liver-related events.
The committee members voted 15-1 to defer approval until clinical outcome data is submitted and reviewed. The FDA has set a target decision date regarding the accelerated approval of OCA for NASH for June 22, 2023.

Analysis: 40% of information about cirrhosis on TikTok is incorrect
CHICAGO –
TikTok’s short video format is increasingly becoming a major source for news and information, especially for adolescents and young adults. In 2022 the technology news website The Verge reported that about 10% of all U.S. adults regularly get news from TikTok, including an estimated 26% of adults under 30.
“Our study highlights the alarming prevalence of misinformation related to liver disease and cirrhosis on the TikTok platform. This misinformation can potentially lead to harm and poor health outcomes for individuals seeking accurate information about their conditions,” wrote the study authors in their abstract.
The study, which was led by Macklin Loveland, MD, an internal medicine resident at the University of Arizona, Tucson, found that, among 2,223 TikTok posts related to liver disease or cirrhosis as of November 2022, 60.3% were found to have accurate medical information, but the remaining 39.7% contained misinformation.
Some of the misinformation offered highly dubious and potentially dangerous advice, such as “Reishi mushrooms can reverse liver damage,” when in fact there is evidence to suggest that reishi mushrooms, especially in powder form, may be toxic to the liver and may even cause fatal fulminant hepatitis.
In an interview, Dr. Loveland said that much of the good information about liver disease on TikTok seems to come from patients with cirrhosis or other liver diseases who post videos chronicling their experiences, whereas bad information seems to come from people who are trying to pitch a product such as “natural” or “alternative” medicine.
“People who have real-life, firsthand experiences with cirrhosis have a really nice platform to talk about their disease process and share information with other people with similar disease processes, and the majority of them are accurate,” he said. “Where the inaccuracies come in are when people are trying to profit off a product or sell a dietary supplement, and then things go by the wayside.”
It’s important for TikTok users to understand the intentions of other users, he said, and expressed the hope that content mediators within TikTok would help to keep misinformation at bay.
Skyler B. Johnson, MD, assistant professor of radiation oncology at the University of Utah Huntsman Cancer Institute, Salt Lake City, has studied misinformation about cancer on social media, and as he and colleagues reported in the Journal of the National Cancer Institute, of 200 articles on cancer posted on social media sites, 32.5% contained misinformation and 30.5% contained harmful information.
In an interview, Dr. Johnson, who was not involved in the study by Dr. Loveland and colleagues, offered advice for colleagues about countering misinformation.
“What we’re trying to do, as part of our research group, is encourage physicians to take an active role in addressing misinformation with their patients and also in their social networking interactions,” he said. “When I see a new patient with a new diagnosis of cancer, I warn them that they’re going to encounter things online that may or may not be true.”
He noted that, often when physicians instruct patients not to go online to research their disease, the first thing the vast majority of patients do after leaving the office is to jump online.
Instead, Dr. Johnson recommended inoculating patients against misinformation – not to discourage them from going online, but to inform them about the myriad good and bad information sources, and steer them toward trustworthy sites such as government agencies (the National Institutes of Health, Centers for Disease Control and Prevention, etc), academic medical center sites, or select nonprofit organizations, foundations, and medical associations.
“But at the end of the day, even those you have to be somewhat vigilant about, because there are some unscrupulous providers who exploit even those sites,” he added.
Study details
Dr. Loveland and colleagues used the TikTok search engine to look for posts containing the terms “cirrhosis” and “liver disease,” and watched all such videos that turned up in the search from beginning to end. They classified each post as either educational in intent or whether it depicted a firsthand experience with liver disease.
They determined whether each post was accurate or erroneous according to guidelines from the American Association for the Study of Liver Disease, American College of Gastroenterology, and American Gastroenterological Association. They also recorded the number of likes, comments, and the number of times that each video was shared.
Accurate posts were viewed and liked significantly more often than inaccurate ones, and accurate posts had significantly more comments that faulty posts.
However, both accurate and inaccurate posts were shared a similar number of times, suggesting that bad-quality information can metastasize just as easily as good information can be disseminated.
Dr. Loveland and colleagues echoed the recommendations of Dr. Johnson, stating that “health care provides should be aware of the potential for misinformation on social media and should strive to provide their patients with accurate and evidence-based information to inform their health care decisions.”
The study was internally funded. Dr. Loveland and Dr. Johnson reported having no conflicts of interest to disclose.

Harnessing ChatGPT to improve liver disease outcomes
ChatGPT, an artificial intelligence (AI) chatbot, may be helpful for patients with cirrhosis or hepatocellular carcinoma (HCC) and their clinicians by generating easy-to-understand information about the disease, a new study suggests.
; however, the majority of the correct responses were labeled by clinician specialists as “correct but inadequate,” according to the study findings.
The AI tool can also provide empathetic and practical advice to patients and caregivers but falls short in its ability to provide tailored recommendations, the researchers said.
“Patients with cirrhosis and/or liver cancer and their caregivers often have unmet needs and insufficient knowledge about managing and preventing complications of their disease. We found ChatGPT – while it has limitations – can help empower patients and improve health literacy for different populations,” study investigator Brennan Spiegel, MD, director of health services research at Cedars-Sinai, Los Angeles, said in a news release.
The study was published online in Clinical and Molecular Hepatology.
Adjunctive health literacy tool
ChatGPT (Chat Generative Pre-Trained Transformer), developed by OpenAI, is a natural language processing tool that allows users to have personalized conversations with an AI bot capable of providing detailed responses to any question posed.
It has already seen several potential applications in the medical field, but the Cedars-Sinai study is one of the first to examine the chatbot’s ability to answer clinically oriented, disease-specific questions correctly and compare its performance to that of physicians.
The investigators asked ChatGPT 164 questions relevant to patients with cirrhosis and/or HCC across five categories – basic knowledge, diagnosis, treatment, lifestyle, and preventive medicine. The chatbot’s answers were graded independently by two liver transplant specialists.
Overall, ChatGPT answered about 77% of the questions correctly, generating high levels of accuracy in 91 questions across the categories, the researchers reported.
ChatGPT regurgitated extensive knowledge of cirrhosis (79% correct) and HCC (74% correct), but only small proportions were deemed by specialists to be comprehensive (47% in cirrhosis, 41% in HCC).
The chatbot performed better in basic knowledge, lifestyle, and treatment than in the domains of diagnosis and preventive medicine.
The specialists grading ChatGPT felt that 75% of its answers for questions on basic knowledge, treatment, and lifestyle were comprehensive or correct but inadequate. The corresponding percentages for diagnosis and preventive medicine were lower (67% and 50%, respectively). No responses from ChatGPT were graded as completely incorrect.
Responses deemed by the specialists to be “mixed with correct and incorrect/outdated data” were 22% for basic knowledge, 33% for diagnosis, 25% for treatment, 18% for lifestyle, and 50% for preventive medicine.
No substitute for specialists
The investigators also tested ChatGPT on cirrhosis quality measures recommended by the American Association for the Study of Liver Diseases and contained in two published questionnaires. ChatGPT answered 77% of the relevant questions correctly but failed to specify decision-making cutoffs and treatment durations.
ChatGPT also lacked knowledge of variations in regional guidelines, such as HCC screening criteria, but it did offer “practical and multifaceted” advice to patients and caregivers about next steps and adjusting to a new diagnosis.
“We believe ChatGPT to be a very useful adjunctive tool for physicians – not a replacement – but adjunctive tool that provides access to reliable and accurate health information that is easy for many to understand,” Dr. Spiegel said in the news release. “We hope that this can help physicians to empower patients and improve health literacy for patients facing challenging conditions such as cirrhosis and liver cancer.”
ChatGPT could enhance clinician workflow by helping to draft a framework for each tailored question asked by patients and caregivers, the researchers wrote.
“Given the high proportion of either comprehensive or correct but inadequate responses and expected continued improvement over time, we foresee that physicians would only need to revise ChatGPT’s responses to best answer patient queries,” they wrote. “This may not only improve the efficiency of physicians but also decrease the overall cost and burden on the healthcare system.”
In addition, ChatGPT could empower patients to be better informed about their care, the researchers noted.
“This allows for patient-led care and facilitates efficient shared decision-making by providing patients with an additional source of information,” they added.
The study had no specific funding. The authors reported no relevant financial relationships.

Overall, ChatGPT answered about 77% of the questions correctly, generating high levels of accuracy in 91 questions across the categories, the researchers reported.
ChatGPT regurgitated extensive knowledge of cirrhosis (79% correct) and HCC (74% correct), but only small proportions were deemed by specialists to be comprehensive (47% in cirrhosis, 41% in HCC).
The chatbot performed better in basic knowledge, lifestyle, and treatment than in the domains of diagnosis and preventive medicine.
The specialists grading ChatGPT felt that 75% of its answers for questions on basic knowledge, treatment, and lifestyle were comprehensive or correct but inadequate. The corresponding percentages for diagnosis and preventive medicine were lower (67% and 50%, respectively). No responses from ChatGPT were graded as completely incorrect.
Responses deemed by the specialists to be “mixed with correct and incorrect/outdated data” were 22% for basic knowledge, 33% for diagnosis, 25% for treatment, 18% for lifestyle, and 50% for preventive medicine.
No substitute for specialists
The investigators also tested ChatGPT on cirrhosis quality measures recommended by the American Association for the Study of Liver Diseases and contained in two published questionnaires. ChatGPT answered 77% of the relevant questions correctly but failed to specify decision-making cutoffs and treatment durations.
ChatGPT also lacked knowledge of variations in regional guidelines, such as HCC screening criteria, but it did offer “practical and multifaceted” advice to patients and caregivers about next steps and adjusting to a new diagnosis.
“We believe ChatGPT to be a very useful adjunctive tool for physicians – not a replacement – but adjunctive tool that provides access to reliable and accurate health information that is easy for many to understand,” Dr. Spiegel said in the news release. “We hope that this can help physicians to empower patients and improve health literacy for patients facing challenging conditions such as cirrhosis and liver cancer.”
ChatGPT could enhance clinician workflow by helping to draft a framework for each tailored question asked by patients and caregivers, the researchers wrote.
“Given the high proportion of either comprehensive or correct but inadequate responses and expected continued improvement over time, we foresee that physicians would only need to revise ChatGPT’s responses to best answer patient queries,” they wrote. “This may not only improve the efficiency of physicians but also decrease the overall cost and burden on the healthcare system.”
In addition, ChatGPT could empower patients to be better informed about their care, the researchers noted.
“This allows for patient-led care and facilitates efficient shared decision-making by providing patients with an additional source of information,” they added.
The study had no specific funding. The authors reported no relevant financial relationships.

ChatGPT, an artificial intelligence (AI) chatbot, may be helpful for patients with cirrhosis or hepatocellular carcinoma (HCC) and their clinicians by generating easy-to-understand information about the disease, a new study suggests.
; however, the majority of the correct responses were labeled by clinician specialists as “correct but inadequate,” according to the study findings.
The AI tool can also provide empathetic and practical advice to patients and caregivers but falls short in its ability to provide tailored recommendations, the researchers said.
“Patients with cirrhosis and/or liver cancer and their caregivers often have unmet needs and insufficient knowledge about managing and preventing complications of their disease. We found ChatGPT – while it has limitations – can help empower patients and improve health literacy for different populations,” study investigator Brennan Spiegel, MD, director of health services research at Cedars-Sinai, Los Angeles, said in a news release.
The study was published online in Clinical and Molecular Hepatology.
Adjunctive health literacy tool
ChatGPT (Chat Generative Pre-Trained Transformer), developed by OpenAI, is a natural language processing tool that allows users to have personalized conversations with an AI bot capable of providing detailed responses to any question posed.

FROM CLINICAL AND MOLECULAR HEPATOLOGY
Dried blood spot test validated for HIV, hep B, and hep C
A test that uses a single drop of dried blood to detect HIV, hepatitis B virus, and HCV has been validated and is now in use in some high-risk settings in Denmark, according to research presented at the annual European Congress of Clinical Microbiology & Infectious Diseases.
Molecular biologist Stephen Nilsson-Møller, MSc, and colleagues at the department of clinical microbiology, Copenhagen University Hospital, developed and validated the test, known as the Dried Blood Spot (DBS), for HIV, HBV, and HCV.
The “test that can detect low viral loads for all three viruses from a single drop of blood, and can be done using existing hospital equipment,” Mr. Nilsson-Møller said in an interview. “Importantly, it does not require venipuncture, but can be done from a drop of dried blood from the finger.”
He highlighted the utility of the new test in more challenging settings. “This method is particularly useful in high-risk settings such as homeless shelters, drug rehabilitation centers, and prisons, where needles might be misused, and it can be difficult to convince people to have the more invasive test.”
“Also, in some places – such as in low- and middle-income settings – there is a distinct risk of ruining blood samples before analysis due to limited refrigeration for transit and storage,” he added. “[Standard] blood samples need to be analyzed within 6 hours when kept at room temperature, while dried blood spots can last for 9 months at room temperature and can be mailed to a laboratory with the right equipment to analyze it.”
Tiny amounts of virus detected
Mr. Nilsson-Møller was tasked with developing a test for use by the university’s department of infectious diseases to screen people in high-risk settings in the capital region of Copenhagen. The work forms part of a PhD project by Jonas Demant at the University of Copenhagen, for which he is screening for HIV, HBV, and HCV in drug rehabilitation centers, prisons, and homeless shelters.
The study is the first to use the Hologic Panther system (a nucleic acid amplification test) combining all three viruses, Mr. Nilsson-Møller pointed out. “A tiny amount of virus can be detected because it is a very sensitive platform using transcription-mediated amplification.”
“If it detects low amounts of virus, it will create many copies very quickly, creating a signal that tells us that the sample is positive,” he explained.
The researchers collected whole blood from a finger prick, dried it out on a protein saver card (filter paper), and cut out a 1.2-cm diameter dry blood spot which was then prepared for analysis.
Twenty blood samples with known amounts of HIV, HBV, and HCV were analyzed via the DBS method (60 in total) and the viruses were detected in all of the samples.
To validate the method, the researchers used plasma with a known viral load, and a series of dilutions were performed to determine the lower limit for positive detection of all three viruses.
“Untreated patients typically have above 1 million IU/mL of viral loads in their plasma, and we found that we can detect much lower levels,” said Mr. Nilsson-Møller. “Ideally, 40 mcL of blood is good, but less should be sufficient if the test is on untreated patients.”
Early testing and treatment reduces morbidity and mortality
Elimination of HBV, HCV, and HIV by 2030 is a global health strategy set by the World Health Organization, but to meet this goal, new approaches for diagnostic testing are required. The DBS test for HIV, HBV, and HCV promises to make a significant contribution toward this goal.
“One in two people currently living with HIV is diagnosed late in the course of their infection, and an even larger proportion of the estimated 6 million Europeans living with chronic hepatitis B or C are not aware that they are infected,” said Anastasia Pharris, PhD, from the European Center for Disease Prevention and Control Principal Expert Infectious Diseases.
“Increasing testing coverage and uptake, especially for those most at risk, is an essential element of any strategy to eliminate HBV, HCV, and HIV in the European Union and European Economic Area,” she pointed out.
Dr. Pharris also highlighted that, while HIV, and often HBV infection, require lifelong treatment, HCV infection is now curable within a few weeks. “To maximize the benefits of individual treatment for all three infections, it is critical to test and diagnose people as soon as possible – in itself a challenge given that these infections can typically be asymptomatic for years.
“Early diagnosis of HBV, HCV, or HIV is vital as it allows people to access treatment, which significantly reduces associated long-term morbidity and mortality.
“In many cases, those most at risk of one of these infections are also more vulnerable to infection with one or both of the other viruses, making the argument for integrated testing even stronger,” she said in an interview.
Mr. Nilsson-Møller and Dr. Pharris reported no relevant financial relationships. Aptima kits for validation were provided by Hologic.
