TOPLINE:

Statin usage in patients with metabolic dysfunction–associated steatotic liver disease (MASLD) is associated with a lower long-term risk for all-cause mortality, liver-related events, and progression of liver stiffness.

METHODOLOGY:

• Although many patients with MASLD have indications for statins, including cardiovascular disease, they are not widely used owing to concerns about possible liver damage and muscle weakness.
• Researchers conducted an observational cohort study to evaluate the long-term effects of statin use in 7988 patients (mean age, 53 years; 58.2% women) with MASLD who underwent at least two vibration-controlled transient elastography exams. The study involved 16 centers in the United States, Europe, and Asia.
• Patients were classified into those with compensated advanced chronic liver disease (cACLD; liver stiffness measurement ≥ 10 kPa) and those without cACLD (liver stiffness measurement < 10 kPa). At baseline, 17% of patients had cACLD.
• Statin prescriptions included simvastatin, pravastatin, atorvastatin, rosuvastatin, lovastatin, fluvastatin, and pitavastatin. At baseline, 40.5% of patients used statins.
• The primary outcome was the composite of all-cause mortality and liver-related events, including cirrhosis, hepatocellular carcinoma, or liver-related mortality. Secondary outcomes included changes in liver stiffness assessed over a median follow-up duration of 4.6 years.

TAKEAWAY:

• Statin usage was associated with a 76.7% lower risk for all-cause mortality and a 62% lower risk of liver-related events than non-use (both P < .001).
• Statin use also was associated with a 46% and 55% lower risk for liver stiffness progression in the cACLD and non-cACLD groups, respectively, than non-use (both P < .001).
• No significant association was found between statin use and liver stiffness regression.

IN PRACTICE:

“The results of this cohort study suggest that statin usage may help reduce CVD [cardiovascular disease] morbidity and mortality rates and slow down liver stiffness progression in both cACLD and non-cALCD patients,” the authors wrote.

SOURCE:

The study, led by Xiao-Dong Zhou, The First Affiliated Hospital of Wenzhou Medical University, Wenzhou, China, was published online in Gut.

LIMITATIONS:

The assessment of patients at different intervals may have affected the interpretation of the data. The median follow-up period may be considered short for assessing the progression of CLD. Additionally, residual confounding in statin users could have led to an overestimation of the benefits of statins.

DISCLOSURES:

This study was supported by grants from the National Natural Science Foundation of China and National Key R&D Program of China. Some authors reported receiving personal fees, consulting fees, speaker bureau fees, grants, nonfinancial support, and honoraria for lectures and travel expenses and owning stock options with pharmaceutical and medical device companies outside of the submitted work.

Alcohol-associated liver disease (ALD) is a significant global health concern, accounting for approximately 5% of all disease and injury. In the United States, the prevalence of ALD has increased since 2014, and the trajectory accelerated during the COVID-19 pandemic.

ALD encompasses a spectrum of diseases that includes steatosis, fibrosis, cirrhosis, and hepatocellular carcinoma, as well as related complications. Although earlier stages of ALD may be asymptomatic, hepatologists and gastroenterologists rarely see patients at this point.

“Unfortunately, patients with ALD more often present in late stages of disease (decompensated cirrhosis) as compared with other chronic liver diseases, such as metabolic dysfunction-associated steatotic liver disease or hepatitis C,” Doug A. Simonetto, MD, associate professor of medicine and director of the Gastroenterology and Hepatology Fellowship Program at the Mayo Clinic, Rochester, Minnesota, told this news organization.

Recent data have identified three demographic groups experiencing higher rates of ALD relative to previous periods and who may therefore require special attention. Understanding what makes these groups increasingly susceptible to ALD may allow for improved screening, earlier diagnosis, and potentially the prevention of its most dire consequences.
 

As Women Consume More Alcohol, ALD Follows

Historically, men have had higher rates of alcohol use, heavy drinking, and alcohol disorders than women. But this gender gap has begun to narrow.

Men born in the early 1900s were 2.2 times more likely to drink alcohol and 3.6 times more likely to experience alcohol-related harms than women, according to a 2016 meta-analysis. By the end of the 1990s, however, women’s drinking had begun to catch up. Men still led in these categories, but only by 1.1 and 1.3 times, respectively.

Rates of binge drinking (defined as at least five drinks in men or at least four drinks in women in an approximately 2-hour period) are also converging between the sexes. The authors of a longitudinal analysis hypothesized that an uptick in young women reporting drinking for social reasons — from 53% in 1987 to 87% in 2020 — was a possible cause.

Greater alcohol consumption among women has translated into higher rates of ALD. Analyzing data from the Global Burden of Disease Study 2019, which looked at hundreds of diseases across 204 countries and territories, researchers reported that the worldwide prevalence of ALD among young women (15-49 years) rose within the past decade. Those in the 20- to 24-year-old age group had the most significant increases in ALD prevalence rates.

Recent US statistics highlight the relative imbalance in ALD’s impact on women, according to George F. Koob, PhD, director of the National Institute on Alcohol Abuse and Alcoholism (NIAAA).

“The age-adjusted death rate from alcohol-associated liver cirrhosis increased by 47% between 2000 and 2019, with larger increases for females than for males (83.5% compared to 33%),” Dr. Koob told this news organization. “Larger increases for women are consistent with a general increase in alcohol use among adult women and larger increases in alcohol-related emergency department visits, hospitalizations, and deaths.”

Physiologically, women have a higher risk than men of developing ALD and more severe disease, even at lower levels of alcohol exposure. According to a 2021 review, several proposed mechanisms might play a role, including differences in alcohol metabolism and first-pass metabolism, hormones, and endotoxin and Kupffer cell activation.

Crucially, women are less likely than men to receive in-person therapy or approved medications for alcohol use disorder, according to a 2019 analysis of over 66,000 privately insured adult patients.
 

Certain Ethnic, Racial Minorities Have Higher Rates of ALD

In the United States, rates of ALD and associated complications are higher among certain minority groups, most prominently Hispanic and Native American individuals.

A 2021 analysis of three large US databases found that Hispanic ethnicity was associated with a 17% increased risk for acute-on-chronic liver failure in patients with ALD-related admissions.

Data also show that Hispanic and White patients have a higher proportion of alcoholic hepatitis than African American patients. And for Hispanic patients admitted for alcoholic hepatitis, they incur significantly more total hospital costs despite having similar mortality rates as White patients.

ALD-related mortality appears higher within certain subgroups of Hispanic patient populations. NIAAA surveillance reports track deaths resulting from cirrhosis in the White, Black, and Hispanic populations. From 2000 to 2019, these statistics show that although death rates from cirrhosis decreased for Hispanic White men, they increased for Hispanic White women, Dr. Koob said.

The latest data show that Native American populations are experiencing ALD at relatively higher rates than other racial/ethnic groups as well. An analysis of nearly 200,000 cirrhosis-related hospitalizations found that ALD, including alcoholic hepatitis, was the most common etiology in American Indian/Alaska Native patients. A separate analysis of the National Inpatient Sample database revealed that discharges resulting from ALD were disproportionately higher among Native American women.

As with Hispanic populations, ALD-associated mortality rates are also higher in Native American populations. The death rate from ALD increased for all racial and ethnic groups by 23.4% from 2019 to 2020, but the biggest increase occurred in the American Indian or Alaska Native populations (34.3% increase, from 20.1 to 27 per 100,000 people). Additionally, over the first two decades of the 21st century, mortality rates resulting from cirrhosis were highest among the American Indian and Alaska Native populations, according to a recently published systematic analysis of US health disparities across five racial/ethnic groups.

Discrepancies in these and other minority groups may be due partly to genetic mechanisms, such as the relatively higher frequency of the PNPLA3 G/G polymorphism, a known risk factor for the development of advanced ALD, among those with Native American ancestry. A host of complex socioeconomic factors, such as income discrepancies and access to care, likely contribute too.

Evidence suggests that alcohol screening interventions are not applied equally across various racial and ethnic groups, Dr. Koob noted.

“For instance, Subbaraman and colleagues reported that, compared to non-Hispanic White patients, those who identify as Hispanic, Black, or other race or ethnicity were less likely to be screened for alcohol use during visits to healthcare providers. This was particularly true for those with a high school education or less,” he told this news organization. “However, other studies have not found such disparities.”
 

ALD Rates High in Young Adults, but the Tide May Be Changing

Globally, the prevalence of ALD has increased among both adolescents and young adults since the beginning of the 21st century. The global incidence of alcohol-associated hepatitis in recent years has been greatest among those aged 15-44 years.

In the United States, the increasing rate of ALD-related hospitalizations is primarily driven by the rise in cases of alcoholic hepatitis and acute-on-chronic liver failure among those aged 35 years and younger.

ALD is now the most common indication for liver transplant in those younger than 40 years of age, having increased fourfold between 2003 and 2018.

From 2009 to 2016, people aged 25-34 years experienced the highest average annual increase in cirrhosis-related mortality (10.5%), a trend the authors noted was “driven entirely by alcohol-related liver disease.”

Younger adults may be more susceptible to ALD due to the way they drink.

In a 2021 analysis of the National Health and Nutrition Examination Survey database, the weighted prevalence of harmful alcohol use was 29.3% in those younger than 35 years, compared with 16.9% in those aged 35-64 years. Higher blood alcohol levels resulting from binge drinking may make patients more susceptible to bacterial translocation and liver fibrosis and can increase the likelihood of cirrhosis in those with an underlying metabolic syndrome.

Yet, Dr. Koob said, thinking of “young adults” as one cohort may be misguided because he’s found very different attitudes toward alcohol within that population. Cross-sectional survey data obtained from more than 180,000 young adults indicated that alcohol abstinence increased between 2002 and 2018. Young adults report various reasons for not drinking, ranging from lack of interest to financial and situational barriers (eg, not wanting to interfere with school or work).

“The tide is coming in and out at the same time,” he said. “Younger people under the age of 25 are drinking less each year, are increasingly interested in things like Dry January, and more than half view moderate levels of consumption as unhealthy. People who are 26 years and older are drinking more, are not as interested in cutting back or taking breaks, and are less likely to consider 1 or 2 drinks per day as potentially unhealthy.”

Dr. Koob would like to believe the positive trends around alcohol in the under-25 set prove not only resilient, but someday, dominant.

“We have seen historic increases in alcohol consumption in the last few years — the largest increases in more than 50 years. But we are hopeful that, as the younger cohorts age, we will see lower levels of drinking by adults in mid-life and beyond.”

Evidence suggests that alcohol screening interventions are not applied equally across various racial and ethnic groups, Dr. Koob noted.

“For instance, Subbaraman and colleagues reported that, compared to non-Hispanic White patients, those who identify as Hispanic, Black, or other race or ethnicity were less likely to be screened for alcohol use during visits to healthcare providers. This was particularly true for those with a high school education or less,” he told this news organization. “However, other studies have not found such disparities.”
 

ALD Rates High in Young Adults, but the Tide May Be Changing

Globally, the prevalence of ALD has increased among both adolescents and young adults since the beginning of the 21st century. The global incidence of alcohol-associated hepatitis in recent years has been greatest among those aged 15-44 years.

In the United States, the increasing rate of ALD-related hospitalizations is primarily driven by the rise in cases of alcoholic hepatitis and acute-on-chronic liver failure among those aged 35 years and younger.

ALD is now the most common indication for liver transplant in those younger than 40 years of age, having increased fourfold between 2003 and 2018.

From 2009 to 2016, people aged 25-34 years experienced the highest average annual increase in cirrhosis-related mortality (10.5%), a trend the authors noted was “driven entirely by alcohol-related liver disease.”

Younger adults may be more susceptible to ALD due to the way they drink.

In a 2021 analysis of the National Health and Nutrition Examination Survey database, the weighted prevalence of harmful alcohol use was 29.3% in those younger than 35 years, compared with 16.9% in those aged 35-64 years. Higher blood alcohol levels resulting from binge drinking may make patients more susceptible to bacterial translocation and liver fibrosis and can increase the likelihood of cirrhosis in those with an underlying metabolic syndrome.

Yet, Dr. Koob said, thinking of “young adults” as one cohort may be misguided because he’s found very different attitudes toward alcohol within that population. Cross-sectional survey data obtained from more than 180,000 young adults indicated that alcohol abstinence increased between 2002 and 2018. Young adults report various reasons for not drinking, ranging from lack of interest to financial and situational barriers (eg, not wanting to interfere with school or work).

“The tide is coming in and out at the same time,” he said. “Younger people under the age of 25 are drinking less each year, are increasingly interested in things like Dry January, and more than half view moderate levels of consumption as unhealthy. People who are 26 years and older are drinking more, are not as interested in cutting back or taking breaks, and are less likely to consider 1 or 2 drinks per day as potentially unhealthy.”

Dr. Koob would like to believe the positive trends around alcohol in the under-25 set prove not only resilient, but someday, dominant.

“We have seen historic increases in alcohol consumption in the last few years — the largest increases in more than 50 years. But we are hopeful that, as the younger cohorts age, we will see lower levels of drinking by adults in mid-life and beyond.”

Take a look at any of the evidence-based US obesity treatment guidelines. The key criteria for diagnosing overweight and obesity is based on the body mass index (BMI). 

The guidelines also use BMI to stratify care options to decrease cardiovascular risk. For example, persons with BMI ≥30 are classified as having obesity, and antiobesity medications are recommended. Those with BMI ≥ 40 are classified as having severe obesity, and metabolic bariatric surgery may be appropriate. 

But where did these cutoff points for more and less aggressive treatments come from? These BMI cutoffs are based primarily on mortality data collected from large non-Hispanic White populations, without data on potential differences by gender and ethnicity. In fact, by itself, BMI is an incomplete measure of cardiometabolic risk, especially in a multiethnic clinic with all genders represented.

For example, it is certainly true that those with BMI ≥ 30 have more cardiovascular risk factors than those with BMI < 30. But Asian American individuals have more risk factors at lower BMIs than do White or African American individuals likely because of more visceral fat accumulation at lower BMIs.

Besides the variation in gender and ethnicity, BMI does not take the type and location of body fat into consideration. Adipose tissue in visceral or ectopic areas have much higher risks for disease than subcutaneous adipose tissue because of the associated inflammation. Measures such as waist circumference, waist-to-hip ratio, and skinfold measurements aim to capture this aspect but often fall short because of variation in techniques.

BMI does not account for muscle mass either, so fit athletes and bodybuilders can be classified as having obesity by BMI alone. More accurate body fat percent measures, such as dual-energy X-ray absorptiometry or MRI specifically for ectopic fat, are labor intensive, expensive, and not feasible to perform in a busy primary care or endocrinology clinic.
 

Assessing Risks From Obesity Beyond BMI

Clearly, better risk measures than BMI are needed, but until they are available, supplemental clinical tools can aid diagnosis and treatment decisions at obesity medicine specialty centers, endocrinology and diabetes centers, and those centers that focus on the treatment of obesity.

For example, a seca scale can measure percent body fat by bioelectric impedance analysis. This technique also has its limitations, but for persons who are well hydrated, it can be used as a baseline to determine efficacy of behavioral interventions, such as resistance-exercise training and a high-protein diet to protect muscle mass as the patient loses weight.

A lot also can be gleaned from diet and exercise history, social history, family history, and physical exam as well as laboratory analyses. For example, an Asian American patient with a BMI of 26 who has been gaining weight mostly in the abdominal region after age 35 years is likely to have cardiometabolic risk, and a family history can solidify that. An exam can show signs of acanthosis nigricans or an enlarged liver and generous abdominal adipose tissue. This would be the patient in whom you would want to obtain a hemoglobin A1c measurement in the chance that it is elevated at > 5.7 mg/dL, suggesting high risk for type 2 diabetes. 

A Fibrosis-4 score can assess the risk for liver disease from aspartate transaminase and alanine aminotransferase and platelet count and age, providing clues to cardiometabolic disease risk.

In the next 10, years there may be a better measure for cardiometabolic risk that is more accurate than BMI is. It could be the sagittal abdominal diameter, which has been purported to more accurately measure visceral abdominal fat. But this has not made it to be one of the vital signs in a busy primary care clinic, however. 
 

Will New Body Fat Tools Change Practice?

In the next 10 years, there may be an affordable gadget to scan the body to determine visceral vs subcutaneous deposition of fat — like radiography for tissue. Now, three-dimensional (3D) total-body scanners can obtain body composition, but they are extremely expensive. The more important clinical question is: How will the use of these imaging modalities change your practice protocol for a particular patient? 

Think about the FibroScan, a type of ultrasound used to determine fatty liver disease and fibrosis. We order the test for those patients in whom we already have a strong suspicion for liver disease and, in obesity practices, for fatty liver and metabolic-associated fatty liver disease or metabolic associated steatohepatitis.

The test results do much to educate the patient and help the patient understand the need for aggressive treatment for their obesity. But it doesn’t necessarily change the clinician’s practice protocols and decisions. We would still recommend weight management and medications or surgery to patients regardless of the findings. 

A FibroScan is an expense, and not all primary care or endocrine practitioners may feel it necessary to purchase one for the added benefit of patient education. And I would argue that a 3D body scanner is a great tool but more for educational purposes than to really determine practice decision-making or outcomes. 

In the meantime, an old-fashioned physical examination, along with a thorough medical, social, and family history should give even the busiest primary care provider enough information to decide whether their patient is a candidate for preventive measures to reduce body fat with diet, exercise, and medication as well as whether the patient is a candidate for metabolic bariatric surgery. Higher suspicion of cardiovascular risk at lower BMI ranges for various ethnicities can help primary care providers pick up on the patients with low BMI but who are at higher risk for type 2 diabetes or prediabetes and cardiovascular disease. 

So the answer to whether we need a better measure than the BMI: Yes, we do. We need a physical examination on all patients.

The US Food and Drug Administration (FDA) granted accelerated approval for Livdelzi (seladelpar, Gilead Sciences, Inc.) for primary biliary cholangitis (PBC) in combination with ursodeoxycholic acid (UDCA) in adults who fail to respond adequately to UDCA, or as monotherapy in those who can’t tolerate UDCA. 

Livdelzi, a selective agonist of peroxisome proliferator–activated receptor delta, is not recommended in adults who have or develop decompensated cirrhosis.

PBC is a rare, chronic, autoimmune disease of the bile ducts that affects roughly 130,000 Americans, primarily women, and can cause liver damage and possible liver failure if untreated. The disease currently has no cure.

The FDA approved Livdelzi based largely on results of the phase 3 RESPONSE study, in which the drug significantly improved liver biomarkers of disease activity and bothersome symptoms of pruritus in adults with PBC.

The primary endpoint of the trial was a biochemical response, defined as an alkaline phosphatase (ALP) level < 1.67 times the upper limit of the normal range, with a decrease of 15% or more from baseline, and a normal total bilirubin level, at 12 months.

After 12 months, 62% of patients taking Livdelzi met the primary endpoint vs 20% of patients taking placebo.

In addition, significantly more patients taking Livdelzi than placebo had normalization of the ALP level (25% vs 0%). The average decrease in ALP from baseline was 42.4% in the Livdelzi group vs 4.3% in the placebo group.

At 12 months, alanine aminotransferase and gamma-glutamyl transferase levels were reduced by 23.5% and 39.1%, respectively, in the Livdelzi group compared with 6.5% and 11.4%, respectively, in the placebo group.

A key secondary endpoint was change in patient-reported pruritus.

At baseline, 38.3% of patients in the Livdelzi group and 35.4% of those in the placebo group had moderate to severe pruritus, with a daily numerical rating scale (NRS) score ≥ 4 out of 10.

Among these patients, the reduction from baseline in the pruritus NRS score at month 6 was significantly greater with Livdelzi than with placebo (change from baseline, -3.2 vs -1.7 points). These improvements were sustained through 12 months.

Improvements on the 5-D Itch Scale in both the moderate- to severe-pruritis population and the overall population also favored Livdelzi over placebo for itch relief, which had a positive impact on sleep.

“The availability of a new treatment option that can help reduce [the] intense itching while also improving biomarkers of active liver disease is a milestone for our community,” Carol Roberts, president, The PBCers Organization, said in a news release announcing the approval. 

The most common adverse reactions with Livdelzi were headache, abdominal pain, nausea, abdominal distension, and dizziness.

The company noted that the FDA granted accelerated approval for Livdelzi based on a reduction of ALP. Improvement in survival or prevention of liver decompensation events have not been demonstrated. Continued approval of Livdelzi for PBC may be contingent on verification and description of clinical benefit in confirmatory trial(s).

TOPLINE:

The estimated number of US adults who consumed at least one of the six most frequently reported hepatotoxic botanicals in the last 30 days is similar to the number of patients prescribed potentially hepatotoxic drugs, including nonsteroidal anti-inflammatory drugs (NSAIDs) and simvastatin.

METHODOLOGY:

• Herbal and dietary supplements (HDS) are an increasingly common source of drug hepatotoxicity cases, but their prevalence and the reasons for their use among the general population are uncertain.
• This survey study evaluated nationally representative data from 9685 adults (mean age, 47.5 years; 51.8% women) enrolled in the National Health and Nutrition Examination Survey (NHANES) between January 2017 and March 2020.
• Participants reported their use of HDS and prescription drugs through personal interviews for a 30-day period prior to the survey date.
• Researchers compared the clinical features and baseline demographic characteristics of users of six potentially hepatotoxic botanicals (ie, turmeric, green tea, Garcinia cambogia, black cohosh, red yeast rice, and ashwagandha) with those of nonusers.
• The prevalence of use of these at-risk botanicals was compared with that of widely prescribed potentially hepatotoxic medications, including NSAIDs, simvastatin, and sertraline.

TAKEAWAY:

• In the cohort of 9685 participants, 4.7% of individuals reported consumption of at least one of the six potentially hepatotoxic botanicals in the past 30 days, with turmeric being the most common, followed by green tea.
• Extrapolating the survey data, researchers estimated that 15.6 million US adults use at least one of these six botanicals, which is comparable to the number of those prescribed potentially hepatotoxic drugs, including NSAIDs (14.8 million) and simvastatin (14.0 million). Sertraline use was lower (7.7 million).
• Most individuals used these botanicals without the recommendation of their healthcare provider.
• Those using botanicals were more likely to be older (adjusted odds ratio [aOR], 2.36; P = .04 for 40-59 years; aOR, 3.96; P = .001 for ≥ 60 years), to have some college education (aOR, 4.78; P < .001), and to have arthritis (aOR, 2.27; P < .001) than nonusers.
• The most common reasons for using any of these six potential hepatotoxic botanicals were to improve or maintain health or to prevent health problems or boost immunity.

IN PRACTICE:

“In light of the lack of regulatory oversight on the manufacturing and testing of botanical products, it is recommended that clinicians obtain a full medication and HDS use history when evaluating patients with unexplained symptoms or liver test abnormalities,” the authors wrote.

SOURCE:

The study, led by Alisa Likhitsup, MD, MPH, Division of Gastroenterology and Hepatology, University of Michigan, Ann Arbor, Michigan, was published online in JAMA Network Open. 

LIMITATIONS:

The survey response rate was low at 43.9% for adults aged ≥ 20 years. As NHANES is a cross-sectional study, the causal relationship between consumption of the six botanicals of interest and the development of liver injury could not be determined. The use of HDS products and medications was self-reported in NHANES and not independently verified using source documents.

TOPLINE:

The estimated number of US adults who consumed at least one of the six most frequently reported hepatotoxic botanicals in the last 30 days is similar to the number of patients prescribed potentially hepatotoxic drugs, including nonsteroidal anti-inflammatory drugs (NSAIDs) and simvastatin.

METHODOLOGY:

• Herbal and dietary supplements (HDS) are an increasingly common source of drug hepatotoxicity cases, but their prevalence and the reasons for their use among the general population are uncertain.
• This survey study evaluated nationally representative data from 9685 adults (mean age, 47.5 years; 51.8% women) enrolled in the National Health and Nutrition Examination Survey (NHANES) between January 2017 and March 2020.
• Participants reported their use of HDS and prescription drugs through personal interviews for a 30-day period prior to the survey date.
• Researchers compared the clinical features and baseline demographic characteristics of users of six potentially hepatotoxic botanicals (ie, turmeric, green tea, Garcinia cambogia, black cohosh, red yeast rice, and ashwagandha) with those of nonusers.
• The prevalence of use of these at-risk botanicals was compared with that of widely prescribed potentially hepatotoxic medications, including NSAIDs, simvastatin, and sertraline.

TAKEAWAY:

• In the cohort of 9685 participants, 4.7% of individuals reported consumption of at least one of the six potentially hepatotoxic botanicals in the past 30 days, with turmeric being the most common, followed by green tea.
• Extrapolating the survey data, researchers estimated that 15.6 million US adults use at least one of these six botanicals, which is comparable to the number of those prescribed potentially hepatotoxic drugs, including NSAIDs (14.8 million) and simvastatin (14.0 million). Sertraline use was lower (7.7 million).
• Most individuals used these botanicals without the recommendation of their healthcare provider.
• Those using botanicals were more likely to be older (adjusted odds ratio [aOR], 2.36; P = .04 for 40-59 years; aOR, 3.96; P = .001 for ≥ 60 years), to have some college education (aOR, 4.78; P < .001), and to have arthritis (aOR, 2.27; P < .001) than nonusers.
• The most common reasons for using any of these six potential hepatotoxic botanicals were to improve or maintain health or to prevent health problems or boost immunity.

IN PRACTICE:

“In light of the lack of regulatory oversight on the manufacturing and testing of botanical products, it is recommended that clinicians obtain a full medication and HDS use history when evaluating patients with unexplained symptoms or liver test abnormalities,” the authors wrote.

SOURCE:

The study, led by Alisa Likhitsup, MD, MPH, Division of Gastroenterology and Hepatology, University of Michigan, Ann Arbor, Michigan, was published online in JAMA Network Open. 

LIMITATIONS:

The survey response rate was low at 43.9% for adults aged ≥ 20 years. As NHANES is a cross-sectional study, the causal relationship between consumption of the six botanicals of interest and the development of liver injury could not be determined. The use of HDS products and medications was self-reported in NHANES and not independently verified using source documents.

This study did not report any source of funding. Two authors declared receiving grants from pharmaceutical companies outside the submitted work.

TOPLINE:

Greater availability of peripheral tri-iodothyronine (T3), indicated by higher concentrations of free T3, T3, and T3/thyroxine (T4) ratio, is associated with increased liver fat content at baseline and a greater liver fat reduction following a dietary intervention known to reduce liver fat.

METHODOLOGY:

• Systemic hypothyroidism and subclinical hypothyroidism are proposed as independent risk factors for steatotic liver disease, but there are conflicting results in euthyroid individuals with normal thyroid function.
• Researchers investigated the association between thyroid function and intrahepatic lipids in 332 euthyroid individuals aged 50-80 years who reported limited alcohol consumption and had at least one condition for unhealthy aging (eg, cardiovascular disease).
• The analysis drew on a sub-cohort from the NutriAct trial, in which participants were randomly assigned to either an intervention group (diet rich in unsaturated fatty acids, plant protein, and fiber) or a control group (following the German Nutrition Society recommendations).
• The relationship between changes in intrahepatic lipid content and thyroid hormone parameters was evaluated in 243 individuals with data available at 12 months.

TAKEAWAY:

• Higher levels of free T3 and T3/T4 ratio were associated with increased liver fat content at baseline (P = .03 and P = .01, respectively).
• After 12 months, both the intervention and control groups showed reductions in liver fat content, along with similar reductions in free T3, total T3, T3/T4 ratio, and free T3/free T4 ratio (all P < .01).
• Thyroid stimulating hormone, T4, and free T4 levels remained stable in either group during the intervention.
• Participants who maintained higher T3 levels during the dietary intervention experienced a greater reduction in liver fat content over 12 months (Rho = −0.133; P = .039).

IN PRACTICE:

“A higher peripheral concentration of active THs [thyroid hormones] might reflect a compensatory mechanism in subjects with mildly increased IHL [intrahepatic lipid] content and early stages of MASLD [metabolic dysfunction–associated steatotic liver disease],” the authors wrote.

SOURCE:

The study was led by Miriam Sommer-Ballarini, Charité–Universitätsmedizin Berlin, Berlin, Germany. It was published online in the European Journal of Endocrinology.

LIMITATIONS:

Participants younger than 50 years of age and with severe hepatic disease, severe substance abuse, or active cancer were excluded, which may limit the generalizability of the findings. Because the study cohort had only mildly elevated median intrahepatic lipid content at baseline, it may not be suited to address the advanced stages of metabolic dysfunction–associated steatotic liver disease. The study’s findings are based on a specific dietary intervention, which may not be applicable to other dietary patterns or populations.

The Deutsche Forschungsgemeinschaft and German Federal Ministry for Education and Research funded this study. Some authors declared receiving funding, serving as consultants, or being employed by relevant private companies.

Patients with dementia may instead have hepatic encephalopathy and should be screened with the Fibrosis-4 (FIB-4) index for cirrhosis, one of the main causes of the condition, new research suggests.

The study of more than 68,000 individuals in the general population diagnosed with dementia between 2009 and 2019 found that almost 13% had FIB-4 scores indicative of cirrhosis and potential hepatic encephalopathy.

The findings, recently published online in The American Journal of Medicine, corroborate and extend the researchers’ previous work, which showed that about 10% of US veterans with a dementia diagnosis may in fact have hepatic encephalopathy.

“We need to increase awareness that cirrhosis and related brain complications are common, silent, but treatable when found,” said corresponding author Jasmohan Bajaj, MD, of Virginia Commonwealth University and Richmond VA Medical Center, Richmond, Virginia. “Moreover, these are being increasingly diagnosed in older individuals.”

“Cirrhosis can also predispose patients to liver cancer and other complications, so diagnosing it in all patients is important, regardless of the hepatic encephalopathy-dementia connection,” he said.
 

FIB-4 Is Key

Dr. Bajaj and colleagues analyzed data from 72 healthcare centers on 68,807 nonveteran patients diagnosed with dementia at two or more physician visits between 2009 and 2019. Patients had no prior cirrhosis diagnosis, the mean age was 73 years, 44.7% were men, and 78% were White.

The team measured the prevalence of two high FIB-4 scores (> 2.67 and > 3.25), selected for their strong predictive value for advanced cirrhosis. Researchers also examined associations between high scores and multiple comorbidities and demographic factors.

Alanine aminotransferase (ALT), aspartate aminotransferase (AST), and platelet labs were collected up to 2 years after the index dementia diagnosis because they are used to calculate FIB-4.

The mean FIB-4 score was 1.78, mean ALT was 23.72 U/L, mean AST was 27.42 U/L, and mean platelets were 243.51 × 109/µL.

A total of 8683 participants (12.8%) had a FIB-4 score greater than 2.67 and 5185 (7.6%) had a score greater than 3.25.

In multivariable logistic regression models, FIB-4 greater than 3.25 was associated with viral hepatitis (odds ratio [OR], 2.23), congestive heart failure (OR,1.73), HIV (OR, 1.72), male gender (OR, 1.42), alcohol use disorder (OR, 1.39), and chronic kidney disease (OR, 1.38).

FIB-4 greater than 3.25 was inversely associated with White race (OR, 0.76) and diabetes (OR, 0.82).

The associations were similar when using a threshold score of greater than 2.67.

“With the aging population, including those with cirrhosis, the potential for overlap between hepatic encephalopathy and dementia has risen and should be considered in the differential diagnosis,” the authors wrote. “Undiagnosed cirrhosis and potential hepatic encephalopathy can be a treatable cause of or contributor towards cognitive impairment in patients diagnosed with dementia.”

Providers should use the FIB-4 index as a screening tool to detect cirrhosis in patients with dementia, they concluded.

The team’s next steps will include investigating barriers to the use of FIB-4 among practitioners, Dr. Bajaj said.

Incorporating use of the FIB-4 index into screening guidelines “with input from all stakeholders, including geriatricians, primary care providers, and neurologists … would greatly expand the diagnosis of cirrhosis and potentially hepatic encephalopathy in dementia patients,” Dr. Bajaj said.

The study had a few limitations, including the selected centers in the cohort database, lack of chart review to confirm diagnoses in individual cases, and the use of a modified FIB-4, with age capped at 65 years.
 

‘Easy to Miss’

Commenting on the research, Nancy Reau, MD, section chief of hepatology at Rush University Medical Center in Chicago, said that it is easy for physicians to miss asymptomatic liver disease that could progress and lead to cognitive decline.

“Most of my patients are already labeled with liver disease; however, it is not uncommon to receive a patient from another specialist who felt their presentation was more consistent with liver disease than the issue they were referred for,” she said.

Still, even in metabolic dysfunction–associated steatotic liver disease, which affects nearly one third of the population, the condition isn’t advanced enough in most patients to cause symptoms similar to those of dementia, said Dr. Reau, who was not associated with the study.

“It is more important for specialists in neurology to exclude liver disease and for hepatologists or gastroenterologists to be equipped with tools to exclude alternative explanations for neurocognitive presentations,” she said. “It is important to not label a patient as having HE and then miss alternative explanations.”

“Every presentation has a differential diagnosis. Using easy tools like FIB-4 can make sure you don’t miss liver disease as a contributing factor in a patient that presents with neurocognitive symptoms,” Dr. Reau said.

This work was partly supported by grants from Department of Veterans Affairs merit review program and the National Institutes of Health’s National Center for Advancing Translational Science. Dr. Bajaj and Dr. Reau reported no conflicts of interest.

TOPLINE:

An analysis of real-world evidence identified 17 medications, many not previously regarded as potentially hepatotoxic, that have high incidence rates of patient hospitalization for acute liver injury (ALI), offering insights on how to better determine which drugs carry the most significant risk and warrant liver monitoring.

METHODOLOGY:

• Without a systematic approach to classifying medications’ hepatotoxic risk, researchers have used case reports published on the National Institutes of Health’s LiverTox, which doesn’t account for the number of people exposed, to categorize drugs’ likelihood of causing ALI. The objective was to identify the most potentially hepatotoxic medications using real-world incidence rates of severe ALI.
• Researchers analyzed US Department of Veterans Affairs electronic health record data for almost 7.9 million individuals (mean age, 64.4 years; 92.5% men) without preexisting liver or biliary disease who were initiated in an outpatient setting on any one of 194 medications with four or more published reports of hepatotoxicity. Drugs delivered by injection or intravenously, prescribed for alcohol use disorder or liver disease treatment, or used as an anticoagulant were not included in the study.
• The primary outcome measured was hospitalization for severe ALI, defined by alanine aminotransferase levels > 120 U/L and total bilirubin levels > 2.0 mg/dL or the international normalized ratio ≥ 1.5 and total bilirubin levels > 2.0 mg/dL within the first 2 days of admission.
• Researchers organized the medications into groups on the basis of observed rates of severe ALI per 10,000 person-years and classified drugs with 10 or more hospitalizations (group 1) and 5-9.9 hospitalizations (group 2) as the most potentially hepatotoxic. The study period was October 2000 through September 2021.

TAKEAWAY:

• Among the study population, 1739 hospitalizations for severe ALI were identified. Incidence rates of severe ALI varied widely by medication, from 0 to 86.4 events per 10,000 person-years.
• Seventeen medications were classified as the most potentially hepatotoxic (groups 1 and 2). Seven of them (stavudine, erlotinib, lenalidomide or thalidomide, chlorpromazine, metronidazole, prochlorperazine, and isoniazid) had incidence rates of ≥ 10 events per 10,000 person-years. The other 10 medications (moxifloxacin, azathioprine, levofloxacin, clarithromycin, ketoconazole, fluconazole, captopril, amoxicillin-clavulanate, sulfamethoxazole-trimethoprim, and ciprofloxacin) showed incidence rates of 5-9.9 events per 10,000 person-years.
• Of the 17 most hepatotoxic medications, 11 (64%) were not classified as highly hepatotoxic in the published case reports, suggesting a discrepancy between real-world data and case report categorizations.
• Similarly, several medications, including some statins, identified as low-risk in this study were classified as among the most hepatotoxic in the published case reports.

IN PRACTICE:

“Categorization of hepatotoxicity based on the number of published case reports did not accurately reflect observed rates of severe ALI (acute liver injury),” the researchers wrote. “This study represents a systematic, reproducible approach to using real-world data to measure rates of severe ALI following medication initiation among patients without liver or biliary disease…Patients initiating a medication with a high rate of severe ALI might require closer monitoring of liver-related laboratory tests to detect evolving hepatic dysfunction earlier, which might improve prognosis.”

The study illustrates the potential to use electronic health record data to “revolutionize how we characterize drug-related toxic effects,” not just on the liver but other organs, Grace Y. Zhang, MD, and Jessica B. Rubin, MD, MPH, of the University of California, San Francisco, wrote in an accompanying editorial. “If curated and disseminated effectively…such evidence will undoubtedly improve clinical decision-making and allow for more informed patient counseling regarding the true risks of starting or discontinuing medications.

The study, led by Jessie Torgersen, MD, MHS, MSCE, of the Division of Infectious Diseases, Department of Medicine, Perelman School of Medicine at the University of Pennsylvania, Philadelphia, was published online in JAMA Internal Medicine.

LIMITATIONS:

The researchers listed several limitations, including the possibility that reliance on laboratory tests for ascertainment of acute liver injuries could introduce surveillance bias. The study focused on a population predominantly consisting of men without preexisting liver or biliary disease, so the findings may not be generalizable to women or individuals with liver disease. Additionally, researchers did not perform a causality assessment of all outcomes, did not study medications with fewer than four published case reports, and did not evaluate the influence of dosage.

DISCLOSURES:

This study was partly funded by several grants from the National Institutes of Health. Some authors declared receiving grants and personal fees from some of the funding agencies and other sources outside of this work.

TOPLINE:

An analysis of real-world evidence identified 17 medications, many not previously regarded as potentially hepatotoxic, that have high incidence rates of patient hospitalization for acute liver injury (ALI), offering insights on how to better determine which drugs carry the most significant risk and warrant liver monitoring.

METHODOLOGY:

• Without a systematic approach to classifying medications’ hepatotoxic risk, researchers have used case reports published on the National Institutes of Health’s LiverTox, which doesn’t account for the number of people exposed, to categorize drugs’ likelihood of causing ALI. The objective was to identify the most potentially hepatotoxic medications using real-world incidence rates of severe ALI.
• Researchers analyzed US Department of Veterans Affairs electronic health record data for almost 7.9 million individuals (mean age, 64.4 years; 92.5% men) without preexisting liver or biliary disease who were initiated in an outpatient setting on any one of 194 medications with four or more published reports of hepatotoxicity. Drugs delivered by injection or intravenously, prescribed for alcohol use disorder or liver disease treatment, or used as an anticoagulant were not included in the study.
• The primary outcome measured was hospitalization for severe ALI, defined by alanine aminotransferase levels > 120 U/L and total bilirubin levels > 2.0 mg/dL or the international normalized ratio ≥ 1.5 and total bilirubin levels > 2.0 mg/dL within the first 2 days of admission.
• Researchers organized the medications into groups on the basis of observed rates of severe ALI per 10,000 person-years and classified drugs with 10 or more hospitalizations (group 1) and 5-9.9 hospitalizations (group 2) as the most potentially hepatotoxic. The study period was October 2000 through September 2021.

The combination of the antiviral bulevirtide (Hepcludex) plus pegylated interferon alfa-2a was superior to bulevirtide monotherapy for chronic hepatitis delta (HDV) infection, a multinational phase 2b open-label study in Europe found.

The combination resulted in higher rates of HDV RNA suppression levels at 24 weeks after end of treatment, especially at a higher, 10-mg dose of bulevirtide, according to researchers led by Tarik Asselah, MD. PhD, a professor of medicine and hepatology at Hôpital Beaujon, APHP, Clichy, France, and the University of Paris.

“This response appeared to be maintained from 24-48 weeks after the end of treatment — a finding that supports the concept that sustained undetectable HDV RNA for at least 1 year after treatment is possible in patients with chronic hepatitis D who have been treated with a finite duration of therapy of at least 96 weeks, including 48 weeks of peginterferon alfa-2a therapy,” the investigators wrote in The New England Journal of Medicine.

“As of today, there is no approved treatment for chronic HDV infection in the United States. Pegylated interferon alfa-2a, which is not approved for treatment of HDV, is the only option recommended by US treatment guidelines,” said study corresponding author Fabien Zoulim, MD, PhD, a hepatologist at the Lyon Hepatology Institute and a professor of medicine at the University of Lyon in France, in comments to GI & Hepatology News. “Bulevirtide 2 mg is approved for treating chronic HDV and compensated liver disease, and both bulevirtide and peginterferon are recommended options by the European treatment guidelines.”

The study found that most patients with undetectable HDV RNA levels during treatment-free follow-up showed no reduction in HepB surface antigen (HBsAg), suggesting an undetectable HDV RNA level can be achieved and sustained without HBsAg loss, the authors wrote.

While very small numbers in the combo groups and the higher-dose bulevirtide arm cleared HBsAg, “the study was not powered to evaluate the HBsAg response,” Dr. Zoulim said.

HDV is a defective virus that requires HBsAg for assembly and propagation, the authors noted. It affects as many as 20 million persons worldwide, and as the most severe form of chronic viral hepatitis, is associated with 2-6 times the risk of hepatocellular carcinoma and 2-3 times the risk of death associated with HBV monoinfection.

Though not common in the United States, it affects an estimated 10 to 20 million people worldwide (J Hepatol. 2020 Apr. doi: 10.1016/j.jhep.2020.04.008). One US database study found HepD in 4.6% of patients with HepB infection.

Commenting on the study but not a participant in it, Ahmet O. Gurakar, MD, AGAF, a professor of medicine in the sections of gastroenterology and hepatology at Johns Hopkins School of Medicine in Baltimore, Maryland, said the study findings look promising for the future treatment of HepD, but cautioned that it will be “a slow process to get approval for combination therapy with bulevirtide since the FDA has previously said it needs to see more studies. The findings need to be confirmed in larger groups, but it’s difficult to recruit enough patients in the United States for a trial since hepatitis D is not common in this country — it’s more common in the Mediterranean basin Eastern European populations.”

The Trial

The investigators randomly assigned 174, largely male, patients ages 18-65 (mean, about 41) years to receive one of four treatments:

• Pegylated interferon alfa-2a alone at 180 μg per week) for 48 weeks (n = 24).
• Bulevirtide at a daily dose of 2 mg plus peginterferon alfa-2a at 180 μg per week for 48 weeks, followed by the same daily dose of bulevirtide for 48 weeks (n = 50).
• Bulevirtide at 10 mg plus peginterferon alfa-2a at 180 μg per week for 48 weeks, followed by the same daily dose of bulevirtide for 48 weeks (n = 50).
• Bulevirtide at a daily dose of 10 mg alone for 96 weeks (n = 50).

All were followed for 48 weeks after treatment. The primary comparison was between the 10-mg bulevirtide plus peginterferon alfa-2a group and the 10-mg bulevirtide monotherapy group.

At 24 weeks post-treatment, HDV RNA was undetectable in 17% of patients in the peginterferon alfa-2a group. In the other arms, HDV RNA was undetectable in 32% in the 2-mg bulevirtide plus peginterferon alfa-2a group, in 46% of the 10-mg bulevirtide plus peginterferon alfa-2a group, and in 12% of the 10-mg bulevirtide group.

For the primary comparison, the between-group difference was 34 percentage points (95% confidence interval, 15-50; P < .001).

At 48 weeks after the end of treatment, HDV RNA was undetectable in 25% in the peginterferon alfa-2a group, 26% in the 2-mg bulevirtide plus peginterferon alfa-2a group, 46% in the 10-mg bulevirtide plus peginterferon alfa-2a group, and 12% in the 10-mg bulevirtide group.

Also calling the findings promising, Anna Lok, MBBS, MD, AGAF, a gastroenterologist at the University of Michigan, Ann Arbor, said that, “Given that the European Medicines Agency’s approval is for bulevirtide alone at 2 mg, results of this study should prompt reassessment whether bulevirtide should be used in combination with pegylated interferon in patients with no contraindications, and if 10 mg is more appropriate than a 2-mg dose.”

MILAN — Liver transplantation improves survival in patients with acute-on-chronic liver failure (ACLF), according to interim clinical outcomes of the large, international CHANCE study.

To date, the results show that 3-month post–liver transplantation mortality rates in patients with ACLF grades 2 and 3 were only 9%, which is not significantly different than that of patients with decompensated cirrhosis, with a mortality of 7%.

University College London Hospitals

“Treatment of ACLF is an unmet medical need,” said Rajiv Jalan, MD, professor of hepatology and honorary consultant in hepatology, University College London Hospitals, London, England.

These findings highlight “the inadequacy of current transplant allocation criteria for patients with ACLF 2 and 3,” which is leading to excess mortality on the wait list, he added.

Dr. Jalan presented the interim results at the European Association for the Study of the Liver (EASL) Congress 2024.

If confirmed in the full analysis, these results argue strongly for increasing access to liver transplantation and changing organ allocation for patients with ACLF 2 and 3, he said.
 

Organ Allocation Principally Based on MELD Scores

ACLF, which occurs in patients with cirrhosis and acutely decompensated liver disease admitted to hospital, carries a high, short-term risk for death. The risk for 28-day mortality for ACLF 2 and 3 is between 30% and 90% and characterized by multiorgan failure.

As seen in previous data, even patients on the transplant waiting list with a low Model for End-Stage Liver Disease (MELD) score have a risk for death between 20% and 30% if they are ACLF 2 and 3, Dr. Jalan said.

MELD scores do not consider the risk for death because of failure of extrahepatic organs, he added. Existing worldwide organ allocation systems are principally based on patient MELD scores or its variations; therefore, many patients die on the waiting list.

With this in mind, the CHANCE study aimed to compare 1-year graft and patient survival rates after liver transplantation in patients with ACLF 2 or 3 at the time of transplantation with patients with decompensated cirrhosis without ACLF and transplantation-free survival of patients with ACLF 2 or 3 not listed for liver transplantation.

The multicenter observational study comprised 66 liver transplant centers from 21 countries and over 500 investigators. Recruitment was closed after 1000 patients were enrolled.

Patients were aged 54-56 years, 31%-35% were women, 48%-70% had alcohol-related cirrhosis, and 19%-24% had metabolic dysfunction–associated steatohepatitis. MELD scores ranged from 25 to 36.

For the interim results, Dr. Jalan and colleagues assessed mortality on the waiting list and 3-month post–liver transplantation mortality.

Secondary endpoints included quality of life and cost of care.

Of the 823 patients in the study, they were grouped as follows: 376 patients with ACLF 2 or 3 listed for liver transplantation (group 1), 313 patients with ACLF 0 or 1 and MELD score > 20 listed for liver transplantation (group 2), and 134 patients with ACLF 2 or 3 not listed for liver transplantation (group 3).

Overall, patients in group 1 had very severe ACLF; 177 patients with ACLF 3 had three or more organ failures, Dr. Jalan noted.

“It is interesting to note that, in group 3, there is an overrepresentation of alcohol-related cirrhosis, and this might reflect a bias in transplantation,” he added.

Dr. Jalan highlighted geographical points of difference. Patients in the United States were younger, which could be important when interpreting results of post-transplantation outcomes. In Asia, the majority of the patients were men and primarily from India, where living donor transplantation is commonly performed. In Latin America, only 33% of study participants had alcohol-related cirrhosis in contrast to 67% of those in North America.

However, “comorbidities across the world were similar, and MELD scores were also similar,” Dr. Jalan said.
 

Death or Delisting

Between listing and transplantation, 28% of patients in group 1 either died or were delisted, compared with 16% of those in group 2. In group 3, 85% of patients who were not listed for transplantation in the first place died.

Similar to what has been seen in other studies, nearly 50% of patients with ACLF 3 but a MELD score < 25 on the wait list died or were delisted, Dr. Jalan pointed out, suggesting that these patients are disadvantaged under the current system of waiting list priority.

Geographically, deaths on the wait list were significantly higher in Latin America at 40% than in North America, Europe, and Asia at 20%, 18%, and 13%, respectively.

“This is likely due to low donation rates in Latin America,” Dr. Jalan said.

Turning to 3-month post-transplantation mortality, the rates in groups 1 and 2 were 9% and 7%, respectively.

“This demonstrates very nicely the clear benefit of transplant,” Dr. Jalan said. “The risk of death post transplant, even with ACLF 2 or 3, is not significantly different to those patients with decompensated cirrhosis.”

There was a slightly higher risk for death in patients with ACLF 3 than in those with ACLF 2 at 14% vs 7%, but “the risk of death in these patients if they don’t have transportation is 70%-80%,” he said.

Looking at 3-month post-transplantation mortality by continent, Dr. Jalan highlighted that Latin America showed 16% risk, compared with Asia, Europe, and North America that showed 12%, 7%, and 3% risk, respectively.

“This is probably multifactorial and likely to be influenced by time on the waiting list, quality of organs available, and patient demographics, among other factors,” Dr. Jalan said. When very sick people undergo transplantation, “there is a higher risk of death.”

The patients in this study have waited a long time, “which worsens their situation,” said Dr. Jalan, reinforcing his argument for changing the international organ allocation system to allow earlier access for these patients.
 

‘The Landscape of Organ Allocation Is Extremely Complex’

Comoderator Ana Lleo, MD, PhD, full professor of internal medicine and hepatology, Humanitas University, Milan, Italy, commented that “the number of patients included in this international study is significant,” and that the issue of mortality on the wait list is of great clinical interest.

“The landscape of organ allocation is extremely complex,” she added.

The system for liver transplantation considers a large number of clinical conditions with very diverse benefit profiles, she explained.

“While we would like to offer liver transplantation for all patients with any range of benefit, the current donations are not sufficient to cover the request,” Dr. Lleo said. “Therefore, prioritization remains key.”

The findings do illustrate the inadequacy of current transplantation allocation criteria for patients with ACLF 2 and 3, said Debbie Shawcross, MBBS, PhD, professor of hepatology and chronic liver failure, King’s College Hospital, London, England, who is also serving as vice-secretary of the EASL Governing Board.

However, “this must be balanced by the recognition that the global donor pool of organs available is a finite resource,” she said, echoing Dr. Lleo’s comments.

This calls for wider ethical discussions to avoid disadvantaging more stable, often younger patients with cirrhosis who are listed for transplantation, she added.

Dr. Jalan declared he is the inventor of Ornithine Phenylacetate, licensed by UCL to Mallinckrodt Pharma; a speaker and grant reviewer for Grifols Research Collaboration: Yaqrit; and the founder of Yaqrit, Hepyx, CyberLiver, and Gigabiome. Dr. Lleo declared that she does not have any conflicts relevant to this work but received lecture fees from Gilead, Advanz Pharma, Alfasigma, GSK, Incyte, Gore, AstraZeneca, and Ipsen and consulted for Advanz Pharma, AstraZeneca, Ipsen, GSK, and Dr Falk.

MILAN — Liver transplantation improves survival in patients with acute-on-chronic liver failure (ACLF), according to interim clinical outcomes of the large, international CHANCE study.

To date, the results show that 3-month post–liver transplantation mortality rates in patients with ACLF grades 2 and 3 were only 9%, which is not significantly different than that of patients with decompensated cirrhosis, with a mortality of 7%.

University College London Hospitals

“Treatment of ACLF is an unmet medical need,” said Rajiv Jalan, MD, professor of hepatology and honorary consultant in hepatology, University College London Hospitals, London, England.

These findings highlight “the inadequacy of current transplant allocation criteria for patients with ACLF 2 and 3,” which is leading to excess mortality on the wait list, he added.

Dr. Jalan presented the interim results at the European Association for the Study of the Liver (EASL) Congress 2024.

If confirmed in the full analysis, these results argue strongly for increasing access to liver transplantation and changing organ allocation for patients with ACLF 2 and 3, he said.
 

Organ Allocation Principally Based on MELD Scores

ACLF, which occurs in patients with cirrhosis and acutely decompensated liver disease admitted to hospital, carries a high, short-term risk for death. The risk for 28-day mortality for ACLF 2 and 3 is between 30% and 90% and characterized by multiorgan failure.

As seen in previous data, even patients on the transplant waiting list with a low Model for End-Stage Liver Disease (MELD) score have a risk for death between 20% and 30% if they are ACLF 2 and 3, Dr. Jalan said.

MELD scores do not consider the risk for death because of failure of extrahepatic organs, he added. Existing worldwide organ allocation systems are principally based on patient MELD scores or its variations; therefore, many patients die on the waiting list.

With this in mind, the CHANCE study aimed to compare 1-year graft and patient survival rates after liver transplantation in patients with ACLF 2 or 3 at the time of transplantation with patients with decompensated cirrhosis without ACLF and transplantation-free survival of patients with ACLF 2 or 3 not listed for liver transplantation.

The multicenter observational study comprised 66 liver transplant centers from 21 countries and over 500 investigators. Recruitment was closed after 1000 patients were enrolled.

Patients were aged 54-56 years, 31%-35% were women, 48%-70% had alcohol-related cirrhosis, and 19%-24% had metabolic dysfunction–associated steatohepatitis. MELD scores ranged from 25 to 36.

For the interim results, Dr. Jalan and colleagues assessed mortality on the waiting list and 3-month post–liver transplantation mortality.

Secondary endpoints included quality of life and cost of care.

Of the 823 patients in the study, they were grouped as follows: 376 patients with ACLF 2 or 3 listed for liver transplantation (group 1), 313 patients with ACLF 0 or 1 and MELD score > 20 listed for liver transplantation (group 2), and 134 patients with ACLF 2 or 3 not listed for liver transplantation (group 3).
