Early-onset NAFLD tied to higher cancer risk
TOPLINE:
New research shows that adults who develop nonalcoholic fatty liver disease (NAFLD) before age 45 are at increased risk of developing cancer, particularly digestive system and lung cancer.
METHODOLOGY:
- Researchers conducted a prospective age- and sex-matched cohort study of 63,696 adults (mean age, 51 years; 83% men) in China. The patients were followed for a median of 10 years; 31,848 had NAFLD, and 31,848 were control participants.
- Participants were grouped on the basis of age at the time of diagnosis of new-onset NAFLD: younger than 45, 45-54, 55-64, and 65 and older.
- Multivariable Cox models were used to analyze cancer risk by age at NAFLD onset. Population-attributable fractions were calculated to quantify cancer risk associated with age at NAFLD onset.
TAKEAWAY:
- During follow-up, 2,415 participants were diagnosed with cancer.
- NAFLD onset before age 45 was associated with highest cancer risk in comparison with the risk among control persons (average hazard ratio [AHR], 1.52). Cancer risk decreased as age at NAFLD onset increased (AHR, 1.50 for the 45-54 cohort, 1.13 for the 55-64 cohort, and 0.75 for the 65-and-older cohort).
- Among adults younger than 45 at NAFLD onset, cancers were mainly digestive and lung cancers (AHR, 2.00 and 2.14, respectively).
- Close to 18% of the cancer risk among adults younger than 45 at NAFLD onset was attributed to their fatty liver disease.
IN PRACTICE:
“The increasing incidence of NAFLD among younger populations highlights the underestimation of harmful outcomes associated with this condition,” the authors wrote. “Our findings suggest that early control and intervention against NAFLD progression may be crucial to reduce the occurrence of NAFLD-related cancers and lessen the burden on public health.”
SOURCE:
The study, with first author Chenan Liu, MD, PhD, Beijing Shijitan Hospital, Capital Medical University, was published online in JAMA Network Open.
LIMITATIONS:
The study population was predominantly male, and NAFLD diagnosis relied on ultrasound rather than liver biopsy, potentially missing mild cases. The study lacked data on liver fibrosis elastography measurement and blood biomarkers. For some cancers, incidence rates were low.
DISCLOSURES:
The study was funded by a grant from the National Key Research and Development Program of China. The authors reported no conflicts of interest.

No need to restrict hep C DAA therapy based on alcohol use
TOPLINE:
Alcohol use at any level, including alcohol use disorder (AUD), is not associated with decreased odds of a sustained virologic response (SVR) to direct-acting antiviral (DAA) therapy for chronic hepatitis C virus (HCV) infection. Therefore, DAA therapy should not be withheld from patients who consume alcohol.
METHODOLOGY:
- The researchers examined electronic health records for 69,229 patients (mean age, 63 years; 97% men; 50% non-Hispanic White) who started DAA therapy through the Department of Veterans Affairs between 2014 and 2018.
- Alcohol use categories were abstinent without history of AUD, abstinent with history of AUD, lower-risk consumption, moderate-risk consumption, and high-risk consumption or AUD.
- The primary outcome was SVR, which was defined as undetectable HCV RNA for 12 weeks to 6 months after completion of DAA treatment.
TAKEAWAY:
- Close to half (46.6%) of patients were abstinent without AUD, 13.3% were abstinent with AUD, 19.4% had lower-risk consumption, 4.5% had moderate-risk consumption, and 16.2% had high-risk consumption or AUD.
- Overall, 94.4% of those who started on DAA treatment achieved SVR.
- After adjustment, there was no evidence that any alcohol category was significantly associated with decreased odds of achieving SVR. The odds ratios were 1.09 for abstinent without AUD history, 0.92 for abstinent with AUD history, 0.96 for moderate-risk consumption, and 0.95 for high-risk consumption or AUD.
- SVR did not differ by baseline stage of hepatic fibrosis, as measured by Fibrosis-4 score of 3.25 or less versus greater than 3.25.
IN PRACTICE:
“Achieving SVR has been shown to be associated with reduced risk of post-SVR outcomes, including hepatocellular carcinoma, liver-related mortality, and all-cause mortality. Our findings suggest that DAA therapy should be provided and reimbursed despite alcohol consumption or history of AUD. Restricting access to DAA therapy according to alcohol consumption or AUD creates an unnecessary barrier to patients accessing DAA therapy and challenges HCV elimination goals,” the investigators wrote.
SOURCE:
Emily J. Cartwright, MD, of Emory University, Atlanta, led the study, which was published online in JAMA Network Open.
LIMITATIONS:
The study was observational and subject to potential residual confounding. To define SVR, HCV RNA was measured 6 months after DAA treatment ended, which may have resulted in a misclassification of patients who experienced viral relapse. Most participants were men born between 1945 and 1965, and the results may not be generalizable to women and/or older and younger patients.
DISCLOSURES:
The study was supported by grants from the National Institute on Alcohol Abuse and Alcoholism. Dr. Cartwright reported no disclosures. Two coauthors disclosed fees from pharmaceutical companies outside the submitted work.

Primary care clinicians should spearhead HIV prevention
HIV continues to be a significant public health concern in the United States, with an estimated 1.2 million people currently living with the virus and more than 30,000 new diagnoses in 2020 alone.
Primary care clinicians can help decrease rates of HIV infection by prescribing pre-exposure prophylaxis to people who are sexually active.
But many do not.
“In medical school, we don’t spend much time discussing sexuality, sexual behavior, sexually transmitted infections, and such, so providers may feel uncomfortable asking what kind of sex their patient is having and with whom, whether they use a condom, and other basics,” said Matthew M. Hamill, MBChB, PhD, MPH, a specialist in sexually transmitted diseases at Johns Hopkins Medicine, Baltimore.
PrEP (pre-exposure prophylaxis) is an antiviral medication that cuts the risk of contracting HIV through sex by around 99% when taken as prescribed, according to the Centers for Disease Control and Prevention.
“Many people who would benefit from PrEP are not receiving this highly effective medication,” said John B. Wong, MD, a primary care internist and professor of medicine at Tufts University, Boston. The gap is particularly acute among Black, Hispanic, and Latino people, who are significantly more likely to be diagnosed with HIV but are much less likely than Whites to receive PrEP, he said.
Dr. Wong, a member of the U.S. Preventive Services Task Force, helped write the group’s new PrEP recommendations. Published in August, the guidelines call for clinicians to prescribe the drugs to adolescents and adults who do not have HIV but are at an increased risk for infection.
“Primary care physicians are ideally positioned to prescribe PrEP for their patients because they have longitudinal relationships: They get to know their patients, and hopefully their patients feel comfortable talking with them about their sexual health,” said Brandon Pollak, MD, a primary care physician and HIV specialist at the Ohio State University College of Medicine, Columbus.
Dr. Pollak, who was not involved with the USPSTF recommendations, cares for patients who are heterosexual and living with HIV.
Clinicians should consider PrEP for all patients who have sex with someone who has HIV, do not use condoms, or have had a sexually transmitted infection within the previous 6 months. Men who have sex with men, transgender women who have sex with men, people who inject illicit drugs or engage in transactional sex, and Black, Hispanic, and Latino individuals also are at increased risk for the infection.
“The vast majority of patients on PrEP in any form sail through with no problems; they have regular lab work and can follow up in person or by telemedicine,” Dr. Hamill said. “They tend to be young, fit people without complicated medical histories, and the medications are very well-tolerated, particularly if people expect some short-term side effects.”
What you need to know when prescribing PrEP
Prescribing PrEP is similar in complexity to prescribing hypertension or diabetes medications, Dr. Hamill said.
Because taking the medications while already infected with the virus can lead to the emergence of drug-resistant HIV, patients must have a negative HIV test before starting PrEP. In addition, the USPSTF recommends testing for other sexually transmitted infections and for pregnancy, if appropriate. The task force also recommends conducting kidney function and hepatitis B tests, and a lipid profile before starting specific types of PrEP.
HIV screening is also recommended at 3-month intervals.
“Providers may order labs done at 3- to 4-month intervals but only see patients in clinic once or twice per year, depending on patient needs and risk behaviors,” said Jill S. Blumenthal, MD, associate professor of medicine at UC San Diego Health.
Clinicians should consider medication adherence and whether a patient is likely to take a pill once a day or could benefit from receiving an injection every 2 months. Patients may experience side effects such as diarrhea or headache with oral PrEP or soreness at the injection site. In rare cases, some of the drugs may cause kidney toxicity or bone mineral loss, according to Dr. Hamill.
Three similarly effective forms of PrEP approved by the U.S. Food and Drug Administration enable clinicians to tailor the medications to the specific needs and preferences of each patient. Truvada (emtricitabine and tenofovir disoproxil fumarate) and Descovy (emtricitabine and tenofovir alafenamide) are both daily tablets, although the latter is not advised for people assigned female sex at birth who have receptive vaginal sex. Apretude (cabotegravir), an injectable agent, is not recommended for people who inject illegal drugs.
Patients with renal or bone disease are not good candidates for Truvada.
“Truvada can decrease bone density, so for someone with osteoporosis, you might choose Descovy or Apretude,” Dr. Pollak said. “For someone with chronic kidney disease, consider Descovy or Apretude. “If a patient has hepatitis B, Truvada or Descovy are appropriate, because hepatitis B is treatable.”
Patients taking an injectable PrEP may need more attention, because the concentration of the medication in the body decreases slowly and may linger for many months at low levels that don’t prevent HIV, according to Dr. Hamill. Someone who acquires HIV during that “tail” period might develop resistance to PrEP.
New research also showed that Descovy users were at elevated risk of developing hypertension and statin initiation, especially among those over age 40 years.
Primary care physicians may want to consult with renal specialists about medication safety in patients with severe kidney disease or with rheumatologists or endocrinologists about metabolic bone disease concerns, Dr. Hamill said.
Meanwhile, if a person begins a monogamous relationship and their risk for HIV drops, “it’s fine to stop taking PrEP tablets,” Dr. Pollak said. “I would still recommend routine HIV screening every 6 or 12 months or however often, depending on other risk factors.”
Caring for these patients entails ensuring labs are completed, monitoring adherence, ordering refills, and scheduling regular follow-up visits.
“For the vast majority of patients, the primary care physician is perfectly equipped for their care through the entire PrEP journey, from discussion and initiation to provision of PrEP,” and most cases do not require specialist care, Dr. Hamill said.
However, “if PrEP fails, which is exceedingly rare, primary care physicians should refer patients immediately, preferably with a warm handoff, for linkage to HIV care,” Dr. Blumenthal said.
Talking about PrEP opens the door to conversations with patients about sexual health and broader health issues, Dr. Hamill said. Although these may not come naturally to primary care clinicians, training is available. The National Network of STD Clinical Prevention Training Centers, funded by the CDC, trains providers on how to overcome their anxiety and have open, inclusive conversations about sexuality and sexual behaviors with transgender and gender-diverse, nonbinary people.
“People worry about saying the wrong thing, about causing offense,” Dr. Hamill said. “But once you get comfortable discussing sexuality, you may open conversations around other health issues.”
Barriers for patients
The task force identified several barriers to PrEP access for patients because of lack of trusting relationships with health care, the effects of structural racism on health disparities, and persistent biases within the health care system.
Racial and ethnic disparities in HIV incidence persist, with 42% of new diagnoses occurring among Black people, 27% among Hispanic or Latino people, and 26% among White people in 2020.
Rates of PrEP usage for a year or longer are also low. Sometimes the patient no longer needs PrEP, but barriers often involve the costs of taking time off from work and arranging transportation to clinic visits.
Although nearly all insurance plans and state Medicaid programs cover PrEP, if a patient does not have coverage, the drugs and required tests and office visits can be expensive.
“One of the biggest barriers for all providers is navigating our complicated health system and drug assistance programs,” said Mehri S. McKellar, MD, associate professor of medicine at Duke University School of Medicine, Durham, N.C.
But lower-cost FDA-approved generic emtricitabine/tenofovir disoproxil fumarate is now available, and clinicians can direct patients to programs that help provide the medications at low or no cost.
“Providing PrEP care is straightforward, beneficial, and satisfying,” Dr. Hamill said. “You help people protect themselves from a life-changing diagnosis, and the health system doesn’t need to pay the cost of treating HIV. Everyone wins.”
Dr. Hamill, Dr. McKellar, Dr. Pollak, and Dr. Wong have reported no relevant financial relationships. Dr. Blumenthal has reported a financial relationship with Gilead Sciences.

Dr. Wong, a member of the U.S. Preventive Services Task Force, helped write the group’s new PrEP recommendations. Published in August, the guidelines call for clinicians to prescribe the drugs to adolescents and adults who do not have HIV but are at an increased risk for infection.
“Primary care physicians are ideally positioned to prescribe PrEP for their patients because they have longitudinal relationships: They get to know their patients, and hopefully their patients feel comfortable talking with them about their sexual health,” said Brandon Pollak, MD, a primary care physician and HIV specialist at the Ohio State University College of Medicine, Columbus.
Dr. Pollak, who was not involved with the USPSTF recommendations, cares for patients who are heterosexual and living with HIV.
Clinicians should consider PrEP for all patients who have sex with someone who has HIV, do not use condoms, or have had a sexually transmitted infection within the previous 6 months. Men who have sex with men, transgender women who have sex with men, people who inject illicit drugs or engage in transactional sex, and Black, Hispanic, and Latino individuals also are at increased risk for the infection.
“The vast majority of patients on PrEP in any form sail through with no problems; they have regular lab work and can follow up in person or by telemedicine,” Dr. Hamill said. “They tend to be young, fit people without complicated medical histories, and the medications are very well-tolerated, particularly if people expect some short-term side effects.”
What you need to know when prescribing PrEP
Prescribing PrEP is similar in complexity to prescribing hypertension or diabetes medications, Dr. Hamill said.
Because taking the medications while already infected with the virus can lead to the emergence of drug-resistant HIV, patients must have a negative HIV test before starting PrEP. In addition, the USPSTF recommends testing for other sexually transmitted infections and for pregnancy, if appropriate. The task force also recommends conducting kidney function and hepatitis B tests, and a lipid profile before starting specific types of PrEP.
HIV screening is also recommended at 3-month intervals.
“Providers may order labs done at 3- to 4-month intervals but only see patients in clinic once or twice per year, depending on patient needs and risk behaviors,” said Jill S. Blumenthal, MD, associate professor of medicine at UC San Diego Health.
Clinicians should consider medication adherence and whether a patient is likely to take a pill once a day or could benefit from receiving an injection every 2 months. Patients may experience side effects such as diarrhea or headache with oral PrEP or soreness at the injection site. In rare cases, some of the drugs may cause kidney toxicity or bone mineral loss, according to Dr. Hamill.
Three similarly effective forms of PrEP approved by the U.S. Food and Drug Administration enable clinicians to tailor the medications to the specific needs and preferences of each patient. Truvada (emtricitabine and tenofovir disoproxil fumarate) and Descovy (emtricitabine and tenofovir alafenamide) are both daily tablets, although the latter is not advised for people assigned female sex at birth who have receptive vaginal sex. Apretude (cabotegravir), an injectable agent, is not recommended for people who inject illegal drugs.
Patients with renal or bone disease are not good candidates for Truvada.
“Truvada can decrease bone density, so for someone with osteoporosis, you might choose Descovy or Apretude,” Dr. Pollak said. “For someone with chronic kidney disease, consider Descovy or Apretude. “If a patient has hepatitis B, Truvada or Descovy are appropriate, because hepatitis B is treatable.”
Patients taking an injectable PrEP may need more attention, because the concentration of the medication in the body decreases slowly and may linger for many months at low levels that don’t prevent HIV, according to Dr. Hamill. Someone who acquires HIV during that “tail” period might develop resistance to PrEP.
New research also showed that Descovy users were at elevated risk of developing hypertension and statin initiation, especially among those over age 40 years.
Primary care physicians may want to consult with renal specialists about medication safety in patients with severe kidney disease or with rheumatologists or endocrinologists about metabolic bone disease concerns, Dr. Hamill said.
Meanwhile, if a person begins a monogamous relationship and their risk for HIV drops, “it’s fine to stop taking PrEP tablets,” Dr. Pollak said. “I would still recommend routine HIV screening every 6 or 12 months or however often, depending on other risk factors.”
Caring for these patients entails ensuring labs are completed, monitoring adherence, ordering refills, and scheduling regular follow-up visits.
“For the vast majority of patients, the primary care physician is perfectly equipped for their care through the entire PrEP journey, from discussion and initiation to provision of PrEP,” and most cases do not require specialist care, Dr. Hamill said.
However, “if PrEP fails, which is exceedingly rare, primary care physicians should refer patients immediately, preferably with a warm handoff, for linkage to HIV care,” Dr. Blumenthal said.
Talking about PrEP opens the door to conversations with patients about sexual health and broader health issues, Dr. Hamill said. Although these may not come naturally to primary care clinicians, training is available. The National Network of STD Clinical Prevention Training Centers, funded by the CDC, trains providers on how to overcome their anxiety and have open, inclusive conversations about sexuality and sexual behaviors with transgender and gender-diverse, nonbinary people.
“People worry about saying the wrong thing, about causing offense,” Dr. Hamill said. “But once you get comfortable discussing sexuality, you may open conversations around other health issues.”
Barriers for patients
The task force identified several barriers to PrEP access for patients because of lack of trusting relationships with health care, the effects of structural racism on health disparities, and persistent biases within the health care system.
Racial and ethnic disparities in HIV incidence persist, with 42% of new diagnoses occurring among Black people, 27% among Hispanic or Latino people, and 26% among White people in 2020.
Rates of PrEP usage for a year or longer are also low. Sometimes the patient no longer needs PrEP, but barriers often involve the costs of taking time off from work and arranging transportation to clinic visits.
Although nearly all insurance plans and state Medicaid programs cover PrEP, if a patient does not have coverage, the drugs and required tests and office visits can be expensive.
“One of the biggest barriers for all providers is navigating our complicated health system and drug assistance programs,” said Mehri S. McKellar, MD, associate professor of medicine at Duke University School of Medicine, Durham, N.C.
But lower-cost FDA-approved generic emtricitabine/tenofovir disoproxil fumarate is now available, and clinicians can direct patients to programs that help provide the medications at low or no cost.
“Providing PrEP care is straightforward, beneficial, and satisfying,” Dr. Hamill said. “You help people protect themselves from a life-changing diagnosis, and the health system doesn’t need to pay the cost of treating HIV. Everyone wins.”
Dr. Hamill, Dr. McKellar, Dr. Pollak, and Dr. Wong have reported no relevant financial relationships. Dr. Blumenthal has reported a financial relationship with Gilead Sciences.

NAFLD raises risk for colorectal adenomatous polyps
TOPLINE:
Nonalcoholic fatty liver disease (NAFLD) is an independent risk factor for precancerous colorectal adenomatous polyps in men and women, according to results of a large study.
METHODOLOGY:
- Researchers conducted a retrospective review of the medical records of adults who underwent abdominal ultrasound and colonoscopy at a single hospital in China from January 2018 to December 2022 to determine NAFLD status and presence of polyps.
- Multivariate logistic regression analysis was used to detect associations between NAFLD and adenomatous and nonadenomatous polyps.
TAKEAWAY:
- Overall, 36.6% of the 3,028 patients had adenomatous polyps, 10.7% had nonadenomatous polyps, and 52.7% were polyp free.
- The higher frequency of NAFLD was significant in adults with adenomatous polyps (66.9%) but not in patients with nonadenomatous polyps (57%) vs. adults with no polyps (52.3%).
- In the fully adjusted model, NAFLD was a significant independent risk factor for adenomatous polyps (odds ratio [OR], 1.6; P < .0001) but not for nonadenomatous polyps (OR, 1.0; P = .813).
- The association between NAFLD and adenomatous polyps was statistically significant in both men (OR, 1.8) and women (OR, 1.4).
IN PRACTICE:
“Our results clearly demonstrated that NAFLD is associated with the development of colorectal adenomatous polyps in males and females, but is not associated with an increased risk of nonadenomatous polyps. The findings provide new insight into the prevention of colorectal cancer in NAFLD patients,” the authors wrote.
SOURCE:
The study was co-led by Yingxue Yang and Yajie Teng, The First People’s Hospital of Kunshan, Suzhou, China. It was published online in the European Journal of Gastroenterology & Hepatology. The study had no specific funding.
LIMITATIONS:
The diagnosis of NAFLD was by ultrasound rather than by liver biopsy. The study’s cross-sectional design precludes conclusions about causality between NAFLD and the risk for colorectal adenomatous polyps. The study involved a single center.
DISCLOSURES:
The authors have disclosed no conflicts of interest.

New consensus on managing acetaminophen poisoning
TOPLINE:
An expert panel has updated recommendations for emergency department assessment, management, and treatment of acetaminophen poisoning.
METHODOLOGY:
The United States and Canada have no formal guidelines for managing acetaminophen poisoning, which is characterized by hepatocellular damage and potential liver failure, which can be life-threatening.
The past 25 years has seen the introduction of products that contain greater amounts of acetaminophen, extended-release preparations, and new drugs that combine acetaminophen with opioids or other ingredients.
From the medical literature and current poison control guidelines, the panel used a modified Delphi method to create a decision framework and determine appropriate management, including triage and laboratory evaluation, for acetaminophen poisoning, addressing scenarios such as extended-release and high-risk ingestion, co-ingestion of anticholinergics or opioids, pregnancy, weight greater than 100 kg, and criteria for consultation with a toxicologist.
TAKEAWAY:
The panel emphasized the role of the patient’s history; an inaccurate estimate of the time of ingestion, for example, can lead to the erroneous conclusion that acetylcysteine, a medication used to treat overdose, is not needed or can be discontinued prematurely – a potentially fatal mistake.
The initial dose of acetylcysteine should be administered as soon as the need becomes evident, with the panel recommending at least 300 mg/kg orally or intravenously during the first 20 or 24 hours of treatment.
Management of ingestion of extended-release preparations is the same, with the exception of obtaining a second acetaminophen blood concentration in some cases.
When acetaminophen is co-ingested with anticholinergic or opioid agonist medications, management is the same, except if the first acetaminophen concentration measured at 4-24 hours after ingestion is 10 mcg/mL or less, another measurement and acetylcysteine treatment are not needed.
IN PRACTICE:
“A guideline that provides management guidance could optimize patient outcomes, reduce disruption for patients and caregivers, and reduce costs by shortening the length of hospitalization,” write the authors.
SOURCE:
The study was conducted by Richard C. Dart, MD, PhD, Rocky Mountain Poison and Drug Safety, University of Colorado, Denver, and colleagues. It was published online in JAMA Network Open.
LIMITATIONS:
The work lacked high-quality data that address clinical decisions needed for managing acetaminophen poisoning. There were only a few well-controlled comparative studies, which focused on specific issues and not on patient management.
DISCLOSURES:
The work was supported by a grant from Johnson & Johnson Consumer Inc. Dr. Dart has reported receiving grants from Johnson & Johnson outside the submitted work. See paper for disclosures of other authors.

A decade after first DAA, only one in three are HCV free
In the decade since safe, curative oral treatments were approved for treating hepatitis C virus (HCV) infections, only one in three U.S. patients diagnosed with the disease have been cleared of it, according to new data from the Centers for Disease Control and Prevention.
The findings indicate that current progress falls far short of the goal of the Viral Hepatitis National Strategic Plan for the United States, which calls for eliminating HCV for at least 80% of patients with the virus by 2030.
Lead author Carolyn Wester, MD, with the CDC’s Division of Viral Hepatitis, called the low numbers “stunning” and said that the researchers found that patients face barriers to being cured at every step of the way, from being diagnosed to accessing breakthrough direct-acting antiviral (DAA) agents.
The article was published online in the CDC’s Morbidity and Mortality Weekly Report.
Outcomes vary by age and insurance
Using longitudinal data from Quest Diagnostics laboratories, the researchers identified 1.7 million people who had a history of HCV infection from Jan. 1, 2013, to Dec. 31, 2022.
Of those patients, 1.5 million (88%) were categorized as having undergone viral testing.
Among those who underwent such testing, 1 million (69%) were categorized as having an initial infection. Just 356,807 patients with initial infection (34%) were cured or cleared of HCV. Of those found to be cured or cleared, 23,518 (7%) were found to have persistent infection or reinfection.
Viral clearance varied greatly by insurance. While 45% of the people covered under Medicare experienced viral clearance, only 23% of the uninsured and 31% of those on Medicaid did so.
Age also played a role in viral clearance. It was highest (42%) among those aged 60 and older. Clearance was lowest (24%) among patients in the 20-39 age group, the group most likely to be newly infected in light of the surge in HCV cases because of the opioid epidemic, Dr. Wester said. Persistent infection or reinfection was also highest in the 20-39 age group.
With respect to age and insurance type combined, the highest HCV clearance rate (49%) was for patients aged 60 and older who had commercial insurance; the lowest (16%) was for uninsured patients in the 20-39 age group.
The investigators evaluated people who had been diagnosed with HCV, Dr. Wester said. “It’s estimated about 40% of people in the U.S. are unaware of their infection.” Because of this, the numbers reported in the study may vastly underestimate the true picture, she told this news organization.
Barriers to treatment ‘insurmountable’ without major transformation
Increased access to diagnosis, treatment, and prevention services for persons with or at risk for acquiring hepatitis C needs to be addressed to prevent progression of disease and ongoing transmission and to achieve national hepatitis C elimination goals, the authors wrote.
The biggest barriers to improving HCV clearance are the high cost of treatment, widely varying insurance coverage, insurer restrictions, and challenges in diagnosing the disease, Dr. Wester added.
Overcoming these barriers requires implementation of universal HCV screening recommendations, including HCV RNA testing for all persons with reactive HCV antibody results, provision of treatment for all persons regardless of payer, and prevention services for persons at risk for acquiring new HCV infection, the authors concluded.
“The current barriers are insurmountable without a major transformation in our nation’s response,” Dr. Wester noted.
She expressed her support of the National Hepatitis C Elimination Program, offered as part of the Biden Administration’s 2024 budget proposal. She said that the initiative “is what we need to prevent the needless suffering from hepatitis C and to potentially save not only tens of thousands of lives but tens of billions of health care dollars.”
The three-part proposal includes a national subscription model to purchase DAA agents for those most underserved: Medicaid beneficiaries, incarcerated people, the uninsured, and American Indian and Alaska Native individuals treated through the Indian Health Service.
Under this model, the federal government would negotiate with manufacturers to buy as much treatment as needed for all individuals in the underserved groups.
What can physicians do?
Physicians can help improve HCV treatment and outcomes by being aware of the current testing guidelines, Dr. Wester said.
Guidelines now call for hepatitis C screening at least once in a lifetime for all adults, except in settings where the prevalence of HCV infection is less than 0.1%. They also call for screening during each pregnancy, with the same regional-prevalence exception.
Recommendations include curative treatment “for nearly everybody who is living with hepatitis C,” Dr. Wester added.
These CDC guidelines came out in April 2020, a time when the medical focus shifted to COVID-19, and that may have hurt awareness, she noted.
Physicians can also help by fighting back against non–evidence-based reasons insurance companies give for restricting coverage, Dr. Wester said.
Those restrictions include requiring specialists to prescribe DAA agents instead of allowing primary care physicians to do so, as well as requiring patients to have advanced liver disease or requiring patients to demonstrate sobriety or prove they are receiving counseling prior to their being eligible for treatment, Dr. Wester said.
Prior authorization a problem
Stacey B. Trooskin MD, PhD, MPH, assistant professor of medicine at the University of Pennsylvania in Philadelphia, told this news organization that prior authorization has been a major barrier for obtaining medications. Prior authorization requirements differ by state.
The paperwork must be submitted by already-stretched physician offices, and appeals are common. In that time, the window for keeping patients with HCV in the health care system may be lost, said Dr. Trooskin, chief medical adviser to the National Viral Hepatitis Roundtable.
“We know that about half of all Medicaid programs have removed prior authorization for most patients entirely,” she said, “but there are still half that require prior authorization.”
Action at the federal level is also needed, Dr. Trooskin said.
The countries that are successfully eliminating HCV and have successfully deployed the lifesaving medications provide governmental support for meeting patients where they are, she added.
Support can include inpatient and outpatient substance use disorder treatment programs or support in mental health settings, she noted.
“It’s not enough to want patients to come into their primary care provider and for that primary care provider to screen them,” Dr. Trooskin said. “This is about creating health care infrastructure so that we are finding patients at greatest risk for hepatitis C and integrating hepatitis C treatment into the services they are already accessing.”

In the decade since safe, curative oral treatments were approved for treating hepatitis C virus (HCV) infections, only one in three U.S. patients diagnosed with the disease have been cleared of it, according to new data from the Centers for Disease Control and Prevention.
The findings indicate that current progress falls far short of the goal of the Viral Hepatitis National Strategic Plan for the United States, which calls for eliminating HCV for at least 80% of patients with the virus by 2030.
Lead author Carolyn Wester, MD, with the CDC’s Division of Viral Hepatitis, called the low numbers “stunning” and said that the researchers found that patients face barriers to being cured at every step of the way, from being diagnosed to accessing breakthrough direct-acting antiviral (DAA) agents.
The article was published online in the CDC’s Morbidity and Mortality Weekly Report.
Outcomes vary by age and insurance
Using longitudinal data from Quest Diagnostics laboratories, the researchers identified 1.7 million people who had a history of HCV infection from Jan. 1, 2013, to Dec. 31, 2022.
Of those patients, 1.5 million (88%) were categorized as having undergone viral testing.
Among those who underwent such testing, 1 million (69%) were categorized as having an initial infection. Just 356,807 patients with initial infection (34%) were cured or cleared of HCV. Of those found to be cured or cleared, 23,518 (7%) were found to have persistent infection or reinfection.
Viral clearance varied greatly by insurance. While 45% of the people covered under Medicare experienced viral clearance, only 23% of the uninsured and 31% of those on Medicaid did so.
Age also played a role in viral clearance. It was highest (42%) among those aged 60 and older. Clearance was lowest (24%) among patients in the 20-39 age group, the group most likely to be newly infected in light of the surge in HCV cases because of the opioid epidemic, Dr. Wester said. Persistent infection or reinfection was also highest in the 20-39 age group.
With respect to age and insurance type combined, the highest HCV clearance rate (49%) was for patients aged 60 and older who had commercial insurance; the lowest (16%) was for uninsured patients in the 20-39 age group.
The investigators evaluated people who had been diagnosed with HCV, Dr. Wester said. “It’s estimated about 40% of people in the U.S. are unaware of their infection.” Because of this, the numbers reported in the study may vastly underestimate the true picture, she told this news organization.
Barriers to treatment ‘insurmountable’ without major transformation
Increased access to diagnosis, treatment, and prevention services for persons with or at risk for acquiring hepatitis C needs to be addressed to prevent progression of disease and ongoing transmission and to achieve national hepatitis C elimination goals, the authors wrote.
The biggest barriers to improving HCV clearance are the high cost of treatment, widely varying insurance coverage, insurer restrictions, and challenges in diagnosing the disease, Dr. Wester added.
Overcoming these barriers requires implementation of universal HCV screening recommendations, including HCV RNA testing for all persons with reactive HCV antibody results, provision of treatment for all persons regardless of payer, and prevention services for persons at risk for acquiring new HCV infection, the authors concluded.
“The current barriers are insurmountable without a major transformation in our nation’s response,” Dr. Wester noted.
She expressed her support of the National Hepatitis C Elimination Program, offered as part of the Biden Administration’s 2024 budget proposal. She said that the initiative “is what we need to prevent the needless suffering from hepatitis C and to potentially save not only tens of thousands of lives but tens of billions of health care dollars.”
The three-part proposal includes a national subscription model to purchase DAA agents for those most underserved: Medicaid beneficiaries, incarcerated people, the uninsured, and American Indian and Alaska Native individuals treated through the Indian Health Service.
Under this model, the federal government would negotiate with manufacturers to buy as much treatment as needed for all individuals in the underserved groups.
What can physicians do?
Physicians can help improve HCV treatment and outcomes by being aware of the current testing guidelines, Dr. Wester said.
Guidelines now call for hepatitis C screening at least once in a lifetime for all adults, except in settings where the prevalence of HCV infection is less than 0.1%. They also call for screening during each pregnancy, with the same regional-prevalence exception.
Recommendations include curative treatment “for nearly everybody who is living with hepatitis C,” Dr. Wester added.
These CDC guidelines came out in April 2020, a time when the medical focus shifted to COVID-19, and that may have hurt awareness, she noted.
Physicians can also help by fighting back against non–evidence-based reasons insurance companies give for restricting coverage, Dr. Wester said.
Those restrictions include requiring specialists to prescribe DAA agents instead of allowing primary care physicians to do so, as well as requiring patients to have advanced liver disease or requiring patients to demonstrate sobriety or prove they are receiving counseling prior to their being eligible for treatment, Dr. Wester said.
Prior authorization a problem
Stacey B. Trooskin MD, PhD, MPH, assistant professor of medicine at the University of Pennsylvania in Philadelphia, told this news organization that prior authorization has been a major barrier for obtaining medications. Prior authorization requirements differ by state.
The paperwork must be submitted by already-stretched physician offices, and appeals are common. In that time, the window for keeping patients with HCV in the health care system may be lost, said Dr. Trooskin, chief medical adviser to the National Viral Hepatitis Roundtable.
“We know that about half of all Medicaid programs have removed prior authorization for most patients entirely,” she said, “but there are still half that require prior authorization.”
Action at the federal level is also needed, Dr. Trooskin said.
The countries that are successfully eliminating HCV and have successfully deployed the lifesaving medications provide governmental support for meeting patients where they are, she added.
Support can include inpatient and outpatient substance use disorder treatment programs or support in mental health settings, she noted.
“It’s not enough to want patients to come into their primary care provider and for that primary care provider to screen them,” Dr. Trooskin said. “This is about creating health care infrastructure so that we are finding patients at greatest risk for hepatitis C and integrating hepatitis C treatment into the services they are already accessing.”

GLP-1 agonists offer multiple benefits in type 2 diabetes with liver cirrhosis
Topline
, new observational data show.
Methodology
- Population-based cohort study using data from the National Health Insurance Research Database of Taiwan.
- Propensity-score matching was used to construct 467 matched pairs of GLP-1 RA users and nonusers (mean age, 57) with T2D and compensated liver cirrhosis.
- All-cause mortality, cardiovascular events, decompensated cirrhosis, and other key outcomes were compared using multivariable-adjusted Cox proportional hazards models.
Takeaway
- During mean follow-up of about 3 years, rates of death per 1,000 person-years were 27.5 in GLP-1 RA users versus 55.9 in nonusers.
- GLP-1 RA users had a significantly lower risk for mortality (adjusted hazard ratio [aHR], 0.47), cardiovascular events (aHR, 0.6), decompensated cirrhosis (aHR, 0.7), hepatic encephalopathy (aHR, 0.59), and liver failure (aHR, 0.54).
- A longer cumulative duration of GLP-1 RA use was associated with lower risk for these outcomes compared with no use.
In practice
“GLP-1 RAs may be a treatment option for diabetes patients with liver cirrhosis. However, additional studies are needed to confirm our results and to explore the mechanisms of GLP-1 RAs, cirrhotic decompensation and hepatic encephalopathy,” the researchers concluded.
Study details
The study was led by Fu-Shun Yen, Dr Yen’s Clinic, Taoyuan, Taiwan. It was published online June 16, 2023, in Clinical Gastroenterology and Hepatology. Funding was provided in part by the Taiwan Ministry of Health and Welfare Clinical Trial Center, China Medical University Hospital, Taipei Veterans General Hospital, and the Ministry of Science and Technology.
Limitations
Limitations of the study include a lack of complete information on family history, diet, body weight, and physical activity, as well as biochemical tests, hemoglobin A1c, pathology, and imaging findings that could potentially influence the results.

What’s new in the new jaundice guidelines?
More than 15 years in the making, the revised AAP Clinical Practice Guideline Revision: Management of Hyperbilirubinemia in the Newborn Infant 35 or More Weeks of Gestation was released in 2022. A key driving force for this revision was the expanded evidence base regarding monitoring and treatment of newborns 35 or more weeks’ gestation to prevent bilirubin encephalopathy and kernicterus.
Here, we summarize the highlights of the new guidelines and point out practical ways to incorporate these guidelines into daily practice.
What has changed?
If you are familiar with the previous guidelines (2004 or the 2009 update) for the management of newborn jaundice, you’ll note that the treatment graphs for phototherapy and exchange transfusion have been updated with new, slightly higher thresholds.
Bilirubin thresholds for starting phototherapy are about 2 mg/dL higher overall than indicated in previous iterations of the guidelines.
This change reflects new evidence that infants don’t typically develop bilirubin neurotoxicity until the total serum bilirubin (TSB) reaches levels well above the previous exchange transfusion threshold, justifying a narrow increase in the bilirubin level for starting phototherapy. Also, phototherapy treatment thresholds are now risk-adjusted, with separate curves for each gestational age from 35 weeks to > 38 weeks.
To find the applicable phototherapy threshold, use the infant’s gestational age (rounding down) and determine whether the infant has even a single neurotoxicity risk factor other than prematurity. Neurotoxicity risk factors include a low albumin level, isoimmune hemolytic disease, glucose-6-phosphate dehydrogenase (G6PD) deficiency, or other hemolytic conditions; sepsis; or any significant clinical instability in the previous 24 hours.
For example, a 384/7 weeks’ gestation newborn has a TSB of 12 mg/dL at 48 hours of age but no neurotoxicity risk factors. Using the graph Phototherapy Thresholds: No Hyperbilirubinemia Neurotoxicity Risk Factors, should the infant be placed under phototherapy at this time? (Answer: No. The threshold for starting phototherapy on this infant is approximately 16 mg/dL.)
When hyperbilirubinemia becomes a medical emergency
A new term, “escalation of care,” has been adopted to describe actions to take when the newborn’s TSB climbs to within 2 mg/dL of the exchange transfusion threshold – a medical emergency. Instructions on how to ensure intensive phototherapy, and when to initiate an urgent exchange transfusion, are given, including the critical need to maintain intensive phototherapy continuously during infant transport and admission to another facility.
Transcutaneous vs. serum bilirubin
Either a serum TSB or a transcutaneous bilirubin (TcB) should be measured in all infants between 24 and 48 hours after birth or before discharge if that occurs earlier. TcB measurements are valid and reliable when used as a screening test to identify infants who require a TSB measurement. Although the two tests are generally correlated, they are not identical, and treatment decisions should be based on TSB levels. A TSB should be obtained if the TcB exceeds or is within 3 mg/dL of the phototherapy treatment threshold, or if the TcB is ≥ 15 mg/dL.
Following up: When to check another bilirubin level
Prior to these new guidelines, the question of when to get the next bilirubin level was based on Vinod Bhutani, MD’s risk nomogram, which classified newborn bilirubin levels within high-, intermediate-, or low-risk zones for needing phototherapy. A bilirubin level in the high-risk zone indicated the need for earlier follow-up. These risk zones have been replaced with a more specific table that provides recommended postdischarge follow-up based on how close the newborn’s bilirubin level is to the hour-specific threshold for treatment. The closer the latest TSB or TcB level is to the newborn’s risk-based phototherapy threshold, the sooner the follow-up to check another bilirubin level will need to be.
Most infants discharged before 72 hours of age will need follow-up within 2 days. Newborns with TSB levels nearing the level for phototherapy (within 2 mg/dL or less) should remain in the hospital.
Five tips for using the new guidelines
Bilitool.org, a popular and useful app, has already been updated to reflect the changes in the new guidelines, making it easy to apply the new thresholds and create a follow-up plan for each patient.
The guidelines provide recommendations for when to check rebound bilirubin levels after stopping phototherapy (hint: babies with neurotoxic risk factors). A TcB device should not be used while the infant is being treated with phototherapy. However, a TcB can be measured once the baby has been off phototherapy for at least 24 hours.
If you have at least two bilirubin measurements, you can calculate the “rate of rise” in bilirubin level. A rapid rate of rise, which serves as a clinical indicator of hemolysis, is defined as ≥ 0.3 mg/dL per hour in the first 24 hours or ≥ 0.2 mg/dL per hour after the first 24 hours of life. This is especially helpful when hemolysis is suspected even if the newborn’s direct antibody test (DAT) is negative. In this scenario, the infant is considered to have a neurotoxic risk factor.
When you initiate phototherapy, be aware of the infant’s bilirubin level threshold for stopping phototherapy (2 mg/dL below the starting phototherapy threshold), as well as the threshold for escalation of care (2 mg/dL below the exchange transfusion threshold).
Because the thresholds for starting phototherapy and initiating exchange transfusion are slightly higher and specific to gestational age, clinicians can more confidently use less phototherapy.
Other guideline highlights
The neurotoxic risk factors and corresponding thresholds are important. If the newborn has one or more neurotoxic risk factors other than prematurity, the neurotoxic risk threshold graph should be used when assessing the need for treatment. Neurotoxic risk thresholds should also be used for newborns whose bilirubin levels continue rising on phototherapy.
The guidelines emphasize that G6PD is one of the most important causes of hazardous hyperbilirubinemia leading to kernicterus in the United States and worldwide. Overall, 13% of African American males and about 4% of African American females have G6PD deficiency.
Finally, the guidelines remind clinicians that an important way to reduce the chances that phototherapy will be needed is to encourage early and frequent feeding (8-12 times in 24 hours).
The AAP Clinical Practice Guideline Revision: Management of Hyperbilirubinemia in the Newborn Infant 35 or More Weeks of Gestation contains a great deal more information, but these basic principles should allow practitioners to begin to incorporate these guidelines into daily practice.

SAFE algorithm detects liver disease in general population
VIENNA – An algorithm, the Steatosis-Associated Fibrosis Estimator (SAFE), was developed to detect clinically significant fibrosis in patients with nonalcoholic fatty liver disease (NAFLD). It is effective at detecting chronic liver disease from all causes with or without NAFLD in the general population, according the results of a U.S. population-based study. The algorithm was designed for use in primary care to help slow the steep rise in liver disease burden.
On the basis of the SAFE score, 61.3% of participants were at low risk for clinically significant fibrosis; 11.2% were at high risk; and 27.5% were at intermediate risk. Upon validation, very few of the low-risk participants had liver fibrosis, while nearly a third of those with a high-risk score had clinically significant fibrosis. In addition, a high percentage of the patients with high-risk SAFE scores had viral hepatitis and elevations in ferritin level.
“This is the first time that there has been a test that provides a score to detect low-risk liver disease in primary care,” said Ray Kim, MD, from Stanford (Calif.) University, senior investigator, who was speaking to this news organization at the annual International Liver Congress sponsored by the European Association for the Study of the Liver
“Primary care doctors currently detect liver disease through a serendipitous abnormal finding on ultrasound or blood tests that detect elevated transaminases, and then the patient is referred to a hepatologist, who figures out what is really going on,” said Dr. Kim.
“This approach is limited, so we need to get SAFE into primary care so these doctors can automatically calculate their scores, and if the patient is over 100 [high risk of chronic liver disease], then they need help [referral to a hepatologist].”
Liver deaths sharply rising
Public health data show that more people are dying of liver disease today than previously. Deaths in the United States have doubled over the past 20 years, said Dr. Kim. “If our mission is to help these patients and prevent death, [things are] moving in the wrong direction.”
He stressed that in order to change the direction, “primary care doctors need to engage with the issue and have appropriate tools to identify people with liver disease.”
Most often, the reason for this rise in deaths is that cases are being diagnosed at advanced stages of disease in which reversibility is limited, he added. “We want to move upstream where people might have early-stage disease and where we can intervene and make a difference.”
In an effort to help earlier detection of liver disease, the SAFE score was developed and validated by Dr. Kim and his colleagues to detect clinically significant (greater than stage 2) fibrosis in patients with NAFLD in primary care. The score is based upon age, body mass index, diabetes, platelet level, aspartate and alanine aminotransferase levels, and globulin level. A score of less than zero signifies that a patient is at low risk for liver fibrosis, while a score greater than 100 signifies a high risk of fibrosis. A score between 0 and 99 denotes intermediate risk of fibrosis.
“Unlike other noninvasive tests that detect advanced fibrosis, this one detects early-stage fibrosis. We’ve shown that the SAFE estimator is better than all other blood-based markers,” explained Dr. Kim.
Applying SAFE to the general population
In the study presented here at EASL, Dr. Kim aimed to expand the horizon for SAFE testing to the U.S. general population and to assess whether SAFE was effective in screening for chronic liver disease regardless of steatosis of the liver.
Together with first author Nakia Chung, MD, also from Stanford University, Dr. Kim applied the SAFE score to data from 7,156 participants of the National Health and Nutrition Examination Survey (NHANES) for 2017-2020. NHANES is representative of the noninstitutionalized, civilian population of the United States. It includes broad demographic, clinical, and laboratory data, including transient elastography data. FibroScans were first used in 2017, so the investigators had 3 years of FibroScan data with which to validate the score.
The researchers extrapolated the NHANES sample data to the U.S. population. They found that the proportion of adults with steatosis (CAP score > 274 dB/m) and significant fibrosis (LSM > 8.0 kPa) was 42.7% (95% confidence interval, 41.0%- 44.3%) and 8.9% (7.6%-10.2%), respectively. In addition, 11.3% (10.2%-12.5%) of the adult U.S. population demonstrated a significant amount of alcohol use, 2.3% (1.4%-3.3%) showed evidence of hepatitis B or C, and 5.4% (4.6%-6.2%) had elevated serum ferritin levels.
The researchers then stratified the patients according to previously defined SAFE tiers of low, intermediate, and high risk and projected findings to the U.S. general population.
“When we applied our score to the general population, we found multiple abnormalities in the high-risk groups [SAFE >100] having Fibroscan data that are consistent with stage 2 or higher fibrosis regardless of etiology, “Dr. Kim pointed out.
Results also showed that very few patients with SAFE less than 0 had liver fibrosis (4% among those with liver stiffness measure [LSM] > 8kPa, and 0.8% with LSM > 12kPa). Among those with SAFE > 100, nearly a third (31.5%) had LSM of > 8kPa, and 16.5% had LSM > 12kPa.
In addition to fibrosis, liver abnormalities were common among patients with SAFE greater than 100, including steatosis (68.0%), viral hepatitis (7.0%), and abnormal ferritin levels (12.9%); 10.8% of these patients used alcohol.
“Right now, some patients are referred, but on examination and FibroScan, they might actually be okay, so it it’s a waste of time and money for everyone. We can preempt all of this by doing a blood test and focusing on those people who really need a scan,” said Dr. Kim.
The researcher is now working with primary care colleagues to help further develop and integrate SAFE into the primary care setting.
Fibrosis score in patients with metabolic dysfunction
Also presenting at the same session on population health was Willem Pieter Brouwer, MD, PhD, from Erasmus University Medical Center, Rotterdam, the Netherlands. He reported results of a validation study of a new risk score – the Metabolic Dysfunction-Associated Fibrosis–5 (MAF-5) score – for use for people with metabolic dysfunction who are recommended for screening for liver fibrosis.
“We believe the MAF-5 score may be a good alternative to the FIB-4 [a liver fibrosis biomarker] for use in the referral pathway for liver health evaluation,” remarked Dr. Brouwer. “The clinical practice guidelines recommend using FIB-4 scores, but these have a poor-moderate performance in the population setting.
“We developed and validated our score in a population of 5,500 from the NHANES 2017-2020 cycle and validated the score in populations from Rotterdam, which is a cohort of elderly participants, and in fibrosis among patients with biopsy-proven NAFLD from Colombia and Belgium,” he explained.
He also validated the score against different existing scoring systems and different methods of measuring liver stiffness and validated it for prognostic use to predict all-cause mortality in the NHANES III cohort.
Dr. Brouwer removed age as a factor of his new MAF-5 score; the score is thus stable for patients of all ages and is suitable for detecting liver disease in younger patients. “This is very important because these patients are currently underserved and have the most years of life to win.”
Referring to the SAFE score discussed by Dr. Kim, as well as other scores, he said, “The FIB-4, SAFE, and NFS [NAFLD fibrosis score] all include age in the scores, which causes problems and limitations in aging populations, as more and more patients will be referred due to an increasing score. Hence, the elderly are mostly all referred for liver checkups.”
Dr. Kim and Dr. Brouwer have disclosed no relevant financial relationships.

‘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.
Dr. Harrison is founder of Madrigal Pharmaceuticals.

[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.
