Some GIs receive more industry money than others
Industry payments to U.S. gastroenterologists and hepatologists increased from 2014 to 2016 before beginning to steadily decrease after 2016, but they're largely concentrated among a small few, according to new research published in Gastroenterology.
The study aimed to identify trends in these specialties in the years after the Sunshine Act, enacted in 2010, and the federal program Open Payments, established in 2013.
“Although Open Payments launched in September of 2014, all the joinpoints in our study occurred more than a year later in 2016, suggesting a delay in observable changes in behavior on industry physician relationships,” wrote Xiaohan Ying, MD, of Weill Cornell Medicine in New York, and colleagues. “Since 2016, we have seen a sustained reduction in general industry payments to physicians while research payments remained stable, which is likely the desired outcome of this program.”
That’s also the conclusion of Lawrence Kosinski, MD, MBA, a spokesperson for the American Gastroenterological Association, who was not involved in the study.
“Most all of us are aware of the Sunshine Act and have reacted accordingly, so I am not surprised that reimbursement per physician has declined over the time period,” Dr. Kosinski told this news organization. “Many physicians are very sensitive to their reporting and have decreased their exposures,” said Dr. Kosinski, founder of SonarMD and a member of the Health & Human Services Advisory Committee on Value-Based Payment. “What does surprise me is the marked disparity in payments with a very small number of physicians receiving tremendous reimbursement from speaking engagements and promotions.”
The researchers retrospectively analyzed industry payments to 26,981 practicing pediatric and adults gastroenterologists and hepatologists using the National Plan and Provider Enumeration System and data from Open Payments between January 2014 and December 2020. The researchers excluded education payments and focused on general payments, which “include charitable contribution, speaker fees, consulting fees, ownership and investments, education, entertainment, food and beverages, gift, honoraria, royalty and license, and travel and lodging,” they reported.
Who gets paid, and how much?
While $27.5 million was going to research and grants, most of the payments ($403.3 million) were general payments; out of the total payments to specialists, $30 million went to hepatology, and $400.8 million went to gastroenterology. Nearly all of the general payments ($398.1 million) were for noneducation purposes; 90.5% of general payments went to men and 9.5% went to women, at an average of $17,167 per person. Nearly half the payments (43.8%) were for speaker fees, totaling $174.3 million, followed by 18.4% going to consulting ($73.1 million) and 12.9% going to food and beverages ($51.5 million).
Most of the physicians accepting payments (86.6%) received less than $10,000, but this made up only 8.3% of all payments. Meanwhile, 74% of all the payments, $294.6 million, went to just 3.1% of the physicians, all of whom received more than $100,000.
That breakdown is what most caught Dr. Kosinki’s attention.
“It’s one thing for a speaker to declare that they are receiving funds from pharma, but they never let us know how much,” Dr. Kosinski said. “Some of these speakers are realizing a very significant payment, which could change the opinions of those listening to their presentations.”
The authors reported that a group of 50 top earners (0.2%) received more than $1 million between 2014 and 2020. Their payments totaled $94.8 million and accounted for nearly a quarter (23.8%) of all the payments. All but one of these physicians were men, and one physician has received more than $1 million every year since 2014.
Payments for guideline authors explored
The authors examined payments to practicing U.S. gastroenterologists and hepatologists who helped write clinical guidelines for the following organizations:
- American Gastroenterological Association (AGA).
- American College of Gastroenterology (ACG).
- American Association for the Study of Liver Disease (AASLD).
- North American Society for Pediatric Gastroenterology, Hepatology, and Nutrition (NASPGHAN).
- American Society for Gastrointestinal Endoscopy (ASGE).
The 186 guidelines published between 2014 and 2020 had 632 physician authors, 415 of whom were practicing gastroenterologists and hepatologists in the United States. Most of these physicians (85.8%) received at least one industry payment, with payments to guideline authors totaling $43.6 million.
Similar to the lopsided breakdown for total payments across all physicians, the majority of the payments (87.4%, or $38.1 million) went to one-quarter of the authors, who each received more than $100,000 per person. Meanwhile, 38.2% of the guideline authors received less than $10,000.
“However, these numbers are likely to decrease in the future as professional societies, such as AASLD, require a majority of the guideline authors to be free of conflict of interest relevant to the subject matter,” the authors wrote. They added that members selected as part of the AGA’s guideline development group (GDG) must report all conflicts of interest, including indirect and intellectual ones, and are recused or excluded when appropriate. These guideline development group participants must also forgo speaking and consulting arrangements until one year after the guideline’s publication.
Trends have been shifting
Total industry payments initially grew at a rate of 11.4% a year between 2014 and 2016 before decreasing at a rate of 5.8% per year after 2016 (P = .03). Though a similar trend occurred at the individual level, it did not reach significance.
However, the trend differed slightly between men and women: Payments to men increased 10.4% annually until 2016 then decreased 6.8% per year thereafter, but women’s payments increased 11.3% per year until 2019. Between 2014 and 2019, the amount per person payment dropped 3.5% annually to physicians overall, but payments to women initially increased 35.4% a year between 2014 and 2016 before decreasing.
Although not statistically significant, trends for types of payments showed that speaker and food/beverage fees have been declining since 2016 while consulting fees have been declining since 2014.
“The reduction in industry payments could be due to the Hawthorne effect, where physicians alter their behavior after becoming aware that their payments were being monitored,” the authors wrote. “Although many physicians see themselves as less vulnerable to be biased by industry compensation, studies have shown that even small payments can affect behavior such as prescription pattern. Additionally, studies have found that patients are less likely to trust physicians who have received industry payments.”
The authors acknowledged the role of industry payments in funding clinical trials but noted that pharmaceutical companies themselves have been taking on more design and execution of trials in recent decades. Further, only 6% of all payments went to research and grant funding, a little more than half the payments for food and beverages.
“While industry research funding is undeniably crucial, it simply plays a very small role in total industry compensation for physicians,” the authors wrote. “While speaker events could be beneficial and educational for physicians and other audiences, these events could also be utilized as means to promote specific products. While it is beneficial to seek input from experienced gastroenterologists for novel therapies and devices, actions should be taken to place limitations on industry payments to physicians, especially for the top earners.”
One author reported speaker fees from W.L. Gore & Associates and Cook Medical. The other two others had no disclosures. No external funding was noted. Dr. Kosinski reported having no relevant disclosures.

AAP updates hyperbilirubinemia guideline
Raising phototherapy thresholds and revising risk assessment are among the key changes in the American Academy of Pediatrics’ updated guidelines for managing hyperbilirubinemia in infants 35 weeks’ gestation and older.
“More than 80% of newborn infants will have some degree of jaundice,” Alex R. Kemper, MD, of Nationwide Children’s Hospital, Columbus, Ohio, and coauthors wrote. Careful monitoring is needed manage high bilirubin concentrations and avoid acute bilirubin encephalopathy (ABE) and kernicterus, a disabling neurologic condition.
The current revision, published in Pediatrics, updates and replaces the 2004 AAP clinical practice guidelines for the management and prevention of hyperbilirubinemia in newborns of at least 35 weeks’ gestation.
The guideline committee reviewed evidence published since the previous guidelines were issued in 2004, and addressed similar issues of prevention, risk assessment, monitoring, and treatment.
A notable change from 2004 was the inclusion of a 2009 recommendation update for “universal predischarge bilirubin screening with measures of total serum bilirubin (TSB) or transcutaneous bilirubin (TcB) linked to specific recommendations for follow-up,” the authors wrote.
In terms of prevention, recommendations include a direct antiglobulin test (DAT) for infants whose mother’s antibody screen was positive or unknown. In addition, exclusive breastfeeding is known to be associated with hyperbilirubinemia, but clinicians should support breastfeeding while monitoring for signs of hyperbilirubinemia because of suboptimal feeding, the authors noted. However, the guidelines recommend against oral supplementation with water or dextrose water to prevent hyperbilirubinemia.
For assessment and monitoring, the guidelines advise the use of total serum bilirubin (TSB) as the definitive test for hyperbilirubinemia to guide phototherapy and escalation of care, including exchange transfusion. “The presence of hyperbilirubinemia neurotoxicity risk factors lowers the threshold for treatment with phototherapy and the level at which care should be escalated,” the authors wrote. They also emphasized the need to consider glucose-6-phosphate dehydrogenase deficiency, a genetic condition that decreases protection against oxidative stress and has been identified as a leading cause of hazardous hyperbilirubinemia worldwide.
The guidelines recommend assessing all infants for jaundice at least every 12 hours after delivery until discharge, with TSB or TcB measured as soon as possible for those with suspected jaundice. The complete guidelines include charts for TSB levels to guide escalation of care. “Blood for TSB can be obtained at the time it is collected for newborn screening tests to avoid an additional heel stick,” the authors noted.
The rate of increase in TSB or TcB, if more than one measure is available, may identify infants at higher risk of hyperbilirubinemia, according to the guidelines, and a possible delay of hospital discharge may be needed for infants if appropriate follow-up is not feasible.
In terms of treatment, new evidence that bilirubin neurotoxicity does not occur until concentrations well above those given in the 2004 guidelines justified raising the treatment thresholds, although by a narrow range. “With the increased phototherapy thresholds, appropriately following the current guidelines including bilirubin screening during the birth hospitalization and timely postdischarge follow-up is important,” the authors wrote. The new thresholds, outlined in the complete guidelines, are based on gestational age, hyperbilirubinemia neurotoxicity risk factors, and the age of the infant in hours. However, infants may be treated at lower levels, based on individual circumstances, family preferences, and shared decision-making with clinicians. Home-based phototherapy may be used in some infants, but should not be used if there is a question about the device quality, delivery time, and ability of caregivers to use the device correctly.
“Discontinuing phototherapy is an option when the TSB has decreased by at least 2 mg/dL below the hour-specific threshold at the initiation of phototherapy,” and follow-up should be based on risk of rebound hyperbilirubinemia, according to the guidelines.
“This clinical practice guideline provides indications and approaches for phototherapy and escalation of care and when treatment and monitoring can be safely discontinued,” However, clinicians should understand the rationale for the recommendations and combine them with their clinical judgment, including shared decision-making when appropriate, the authors concluded.
Updated evidence supports escalating care
The take-home message for pediatricians is that neonatal hyperbilirubinemia is a very common finding, and complications are rare, but the condition can result in devastating life-long results, Cathy Haut, DNP, CPNP-AC, CPNP-PC, a pediatric nurse practitioner in Rehoboth Beach, Del., said in an interview.
“Previous guidelines published in 2004 and updated in 2009 included evidence-based recommendations, but additional research was still needed to provide guidance for providers to prevent complications of hyperbilirubinemia,” said Dr. Haut, who was not involved in producing the guidelines.
“New data documenting additional risk factors, the importance of ongoing breastfeeding support, and addressing hyperbilirubinemia as an urgent problem” are additions to prevention methods in the latest published guidelines, she said.
“Acute encephalopathy and kernicterus can result from hyperbilirubinemia with severe and devastating neurologic effects, but are preventable by early identification and treatment,” said Dr. Haut. Therefore, “it is not surprising that the AAP utilized continuing and more recent evidence to support new recommendations. Both maternal and neonatal risk factors have long been considered in the development of neonatal hyperbilirubinemia, but recent recommendations incorporate additional risk factor evaluation and urgency in time to appropriate care. Detailed thresholds for phototherapy and exchange transfusion will benefit the families of full-term infants without other risk factors and escalate care for those neonates with risk factors.”
However, potential barriers to following the guidelines persist, Dr. Haut noted.
“Frequent infant follow-up can be challenging for busy primary care offices with outpatient laboratory results often taking much longer to obtain than in a hospital setting,” she said.
Also, “taking a newborn to the emergency department or an inpatient laboratory can be frightening for families with the risk of illness exposure. Frequent monitoring of serum bilirubin levels is disturbing for parents and inconvenient immediately postpartum,” Dr. Haut explained. “Few practices utilize transcutaneous bilirubin monitoring which may be one method of added screening.”
In addition, “despite the importance of breastfeeding, ongoing support is not readily available for mothers after hospital discharge. A lactation specialist in the office setting can take the burden off providers and add opportunity for family education.”
As for additional research, “continued evaluation of the comparison of transcutaneous bilirubin monitoring and serum levels along with the use of transcutaneous monitoring in facilities outside the hospital setting may be warranted,” Dr. Haut said. “Data collection on incidence and accompanying risk factors of neonates who develop acute hyperbilirubinemia encephalopathy and kernicterus is a long-term study opportunity.”
The guidelines received no external funding. Lead author Dr. Kemper had no financial conflicts to disclose. Dr. Haut had no financial conflicts to disclose and serves on the editorial advisory board of Pediatric News.

“New data documenting additional risk factors, the importance of ongoing breastfeeding support, and addressing hyperbilirubinemia as an urgent problem” are additions to prevention methods in the latest published guidelines, she said.
“Acute encephalopathy and kernicterus can result from hyperbilirubinemia with severe and devastating neurologic effects, but are preventable by early identification and treatment,” said Dr. Haut. Therefore, “it is not surprising that the AAP utilized continuing and more recent evidence to support new recommendations. Both maternal and neonatal risk factors have long been considered in the development of neonatal hyperbilirubinemia, but recent recommendations incorporate additional risk factor evaluation and urgency in time to appropriate care. Detailed thresholds for phototherapy and exchange transfusion will benefit the families of full-term infants without other risk factors and escalate care for those neonates with risk factors.”
However, potential barriers to following the guidelines persist, Dr. Haut noted.
“Frequent infant follow-up can be challenging for busy primary care offices with outpatient laboratory results often taking much longer to obtain than in a hospital setting,” she said.
Also, “taking a newborn to the emergency department or an inpatient laboratory can be frightening for families with the risk of illness exposure. Frequent monitoring of serum bilirubin levels is disturbing for parents and inconvenient immediately postpartum,” Dr. Haut explained. “Few practices utilize transcutaneous bilirubin monitoring which may be one method of added screening.”
In addition, “despite the importance of breastfeeding, ongoing support is not readily available for mothers after hospital discharge. A lactation specialist in the office setting can take the burden off providers and add opportunity for family education.”
As for additional research, “continued evaluation of the comparison of transcutaneous bilirubin monitoring and serum levels along with the use of transcutaneous monitoring in facilities outside the hospital setting may be warranted,” Dr. Haut said. “Data collection on incidence and accompanying risk factors of neonates who develop acute hyperbilirubinemia encephalopathy and kernicterus is a long-term study opportunity.”
The guidelines received no external funding. Lead author Dr. Kemper had no financial conflicts to disclose. Dr. Haut had no financial conflicts to disclose and serves on the editorial advisory board of Pediatric News.
Raising phototherapy thresholds and revising risk assessment are among the key changes in the American Academy of Pediatrics’ updated guidelines for managing hyperbilirubinemia in infants 35 weeks’ gestation and older.
“More than 80% of newborn infants will have some degree of jaundice,” Alex R. Kemper, MD, of Nationwide Children’s Hospital, Columbus, Ohio, and coauthors wrote. Careful monitoring is needed manage high bilirubin concentrations and avoid acute bilirubin encephalopathy (ABE) and kernicterus, a disabling neurologic condition.
The current revision, published in Pediatrics, updates and replaces the 2004 AAP clinical practice guidelines for the management and prevention of hyperbilirubinemia in newborns of at least 35 weeks’ gestation.
The guideline committee reviewed evidence published since the previous guidelines were issued in 2004, and addressed similar issues of prevention, risk assessment, monitoring, and treatment.
A notable change from 2004 was the inclusion of a 2009 recommendation update for “universal predischarge bilirubin screening with measures of total serum bilirubin (TSB) or transcutaneous bilirubin (TcB) linked to specific recommendations for follow-up,” the authors wrote.
In terms of prevention, recommendations include a direct antiglobulin test (DAT) for infants whose mother’s antibody screen was positive or unknown. In addition, exclusive breastfeeding is known to be associated with hyperbilirubinemia, but clinicians should support breastfeeding while monitoring for signs of hyperbilirubinemia because of suboptimal feeding, the authors noted. However, the guidelines recommend against oral supplementation with water or dextrose water to prevent hyperbilirubinemia.
For assessment and monitoring, the guidelines advise the use of total serum bilirubin (TSB) as the definitive test for hyperbilirubinemia to guide phototherapy and escalation of care, including exchange transfusion. “The presence of hyperbilirubinemia neurotoxicity risk factors lowers the threshold for treatment with phototherapy and the level at which care should be escalated,” the authors wrote. They also emphasized the need to consider glucose-6-phosphate dehydrogenase deficiency, a genetic condition that decreases protection against oxidative stress and has been identified as a leading cause of hazardous hyperbilirubinemia worldwide.
The guidelines recommend assessing all infants for jaundice at least every 12 hours after delivery until discharge, with TSB or TcB measured as soon as possible for those with suspected jaundice. The complete guidelines include charts for TSB levels to guide escalation of care. “Blood for TSB can be obtained at the time it is collected for newborn screening tests to avoid an additional heel stick,” the authors noted.
The rate of increase in TSB or TcB, if more than one measure is available, may identify infants at higher risk of hyperbilirubinemia, according to the guidelines, and a possible delay of hospital discharge may be needed for infants if appropriate follow-up is not feasible.
In terms of treatment, new evidence that bilirubin neurotoxicity does not occur until concentrations well above those given in the 2004 guidelines justified raising the treatment thresholds, although by a narrow range. “With the increased phototherapy thresholds, appropriately following the current guidelines including bilirubin screening during the birth hospitalization and timely postdischarge follow-up is important,” the authors wrote. The new thresholds, outlined in the complete guidelines, are based on gestational age, hyperbilirubinemia neurotoxicity risk factors, and the age of the infant in hours. However, infants may be treated at lower levels, based on individual circumstances, family preferences, and shared decision-making with clinicians. Home-based phototherapy may be used in some infants, but should not be used if there is a question about the device quality, delivery time, and ability of caregivers to use the device correctly.
“Discontinuing phototherapy is an option when the TSB has decreased by at least 2 mg/dL below the hour-specific threshold at the initiation of phototherapy,” and follow-up should be based on risk of rebound hyperbilirubinemia, according to the guidelines.
“This clinical practice guideline provides indications and approaches for phototherapy and escalation of care and when treatment and monitoring can be safely discontinued,” However, clinicians should understand the rationale for the recommendations and combine them with their clinical judgment, including shared decision-making when appropriate, the authors concluded.
Updated evidence supports escalating care
The take-home message for pediatricians is that neonatal hyperbilirubinemia is a very common finding, and complications are rare, but the condition can result in devastating life-long results, Cathy Haut, DNP, CPNP-AC, CPNP-PC, a pediatric nurse practitioner in Rehoboth Beach, Del., said in an interview.

Alcohol-related cirrhosis associated with higher risk of fractures, death
Patients with alcohol-related cirrhosis have a higher fracture rate and a higher post-fracture mortality rate, compared with the general population, according to a large new study from Sweden.
Alcohol-related cirrhosis was associated with an almost fourfold increased fracture rate, and the post-fracture mortality rates were higher at both 30 days and 1 year later.
“Half of all fractures were presumably associated with osteoporosis,” write the study authors, who are gastroenterologists and epidemiologists at the Karolinska Institute, Stockholm. “This suggests that existing pharmacotherapy for osteoporosis may reduce the fracture risk in patients with alcohol-related cirrhosis and possibly also reduce mortality rates.”
But, the authors continue, “our data indicate that osteoporosis may not be the only explanatory factor for this increased fracture risk. Removing modifiable risk factors such as smoking, heavy alcohol use, or malnutrition may further reduce the risk of fractures.”
The study was published online in Clinical Gastroenterology and Hepatology.
Analyzing risks
The association between liver cirrhosis and fractures appears strongest in patients with alcohol-related cirrhosis, the most common cause of cirrhosis in many countries, including Sweden, the authors write.
Previous studies have examined mostly relative risk or hip fractures. The authors aimed to determine not only the relative risk but also the absolute risk, which “can better inform clinicians and policymakers of the actual size of the problem,” they write.
In a nationwide population-based cohort study, they analyzed data from the Swedish National Patient Registry between 1969 and 2016, which included 25,090 patients with alcohol-related cirrhosis. Patients were matched for sex, age, and municipality with 239,458 controls from the Swedish Total Population Registry. They calculated the cumulative incidence of fractures and accounted for competing risks, such as death or liver transportation.
Overall, 48,635 fractures occurred during 3.4 million person-years of follow-up, including 3,659 (14.6%) among patients and 44,976 (18.8%) among controls.
Patients with alcohol-related cirrhosis had a 3.8-times higher fracture rate, with 38.7 fractures per 1,000 person-years, compared with 13.3 in controls. Alcohol-related cirrhosis was also associated with a 1.9-times higher fracture rate than nonalcoholic cirrhosis and a 1.3-times higher fracture rate than noncirrhotic alcohol-related liver disease.
The cumulative incidence of fractures was elevated for patients with alcohol-related cirrhosis in the first 19 years of follow-up, with a 5-year risk at nearly 10%, compared with 4.5% for controls, and a 10-year risk of 13.5%, compared with 8.7% for controls.
Among those with a fracture, the median time to death was 2.8 years in patients with alcohol-related cirrhosis and 3.5 years in controls.
Patients with alcohol-related cirrhosis had a 1.6-times higher post-fracture mortality rate at 30 days, as well as a 1.8-times higher post-fracture mortality rate after one year.
“Falls and fractures kill patients with cirrhosis. Data like these are crucial to spread awareness and represent a call to arms,” Elliot Tapper, MD, an assistant professor of gastroenterology at the University of Michigan, Ann Arbor, told this news organization.
Dr. Tapper, who wasn’t involved with this study, researches the health outcomes of patients with cirrhosis. His previous studies have found that falls, injuries, and death are common in patients with cirrhosis, which could be predicted with an algorithm based on a prior history of falls, blood sodium level, mobility, and quality of life.
“The data emphasize that a fall and fracture herald a time of increased risk,” he said. “Research is needed to develop interventions that prevent falls and help patients remain more resilient when they happen.”
Promoting bone health
Osteoporosis was the most common presumed mechanism in both patients with alcohol-related cirrhosis (49.4%) and controls (52.2%), while high-energy trauma from motor vehicle crashes or heights preceded 10.9% of fractures in patients and 13.5% in controls.
The Karolinska Institute study found that patients with alcohol-related cirrhosis had a 4.4-times higher rate of osteoporotic fracture than controls, which remained 3.6-times higher when using a stricter definition of osteoporotic fracture (a diagnosis of osteoporosis before, at, or within 3 months from the date of a fracture of the vertebrae, pelvis, proximal humerus, distal forearm, or hip).
Patients with osteoporosis at baseline had a 2.5-times higher incidence of fractures than controls with baseline osteoporosis. The absolute risk of fractures in patients with alcohol-related cirrhosis and osteoporosis was higher than for controls with osteoporosis during the first 3 years after a cirrhosis diagnosis.
In addition, the post-fracture mortality rate in those with osteoporosis was more than double in patients with cirrhosis in the first 30 days after a fracture and more than tripled after one year.
“Bone health isn’t necessarily prioritized for our patients, even though it is linked to higher mortality and disability,” Arpan Patel, MD, PhD, a hepatologist at the West Los Angeles VA Medical Center and assistant professor at the David Geffen School of Medicine at the University of California, Los Angeles, told this news organization.
Dr. Patel, who wasn’t involved with this study, has researched the associations between osteoporotic fracture risk, hospitalization, and death in patients with cirrhosis.
“Current guidelines support assessing post-liver transplant patients for bone density but do not currently advocate for doing so in patients with cirrhosis or alcohol-associated liver disease, who are a much larger at-risk population,” Dr. Patel said.
“The current paper supports the idea that we should consider the broad ramifications of alcohol use on bone health for our patients and suggests that there should be greater efforts to screen for and manage osteoporosis and osteopenia in our patients earlier,” he added.
The researchers were supported by grants from Region Stockholm and the Syskonen Svensson Foundation, though the funders had no role in the conduct of the study. The study authors reported no other disclosures or conflicts of interest. Dr. Tapper and Dr. Patel report no relevant financial relationships.

FROM CLINICAL GASTROENTEROLOGY AND HEPATOLOGY
New update focuses on NAFLD in lean people
Ongoing follow-up and lifestyle interventions are needed in lean patients with nonalcoholic fatty liver disease (NAFLD), suggests a panel of experts in a recent review.
They also urge screening for NAFLD in individuals who are older than 40 years with type 2 diabetes, even if they are not overweight.
NAFLD is a leading cause of chronic liver disease that affects more than 25% of the United States and worldwide populations, note lead author Michelle T. Long, MD, Boston Medical Center, Boston University, and colleagues.
They add that around one-quarter of those affected have nonalcoholic steatohepatitis, which is associated with significant morbidity and mortality due to complications of liver cirrhosis, hepatic decompensation, and hepatocellular carcinoma.
Although NAFLD occurs primarily in individuals with obesity or type 2 diabetes, between 7%-20% have a lean body habitus, they write.
There are differences in rates of disease progression, associated conditions, and diagnostic and management approaches between lean and non-lean patients, the authors note, but there is limited guidance on the appropriate clinical evaluation of the former group.
The American Gastroenterological Association therefore commissioned an expert review to provide best practice advice on key clinical issues relating to the diagnosis, risk stratification, and treatment of NAFLD in lean individuals.
Their review was published online in Gastroenterology.
Evidence-based approaches
The 15 best practice advice statements covered a wide range of clinical areas, first defining lean as a body mass index (BMI) less than 25 in non-Asian persons and less than 23 in Asian persons.
The authors go on to stipulate, for example, that lean individuals in the general population should not be screened for NAFLD but that screening should be considered for individuals older than 40 years with type 2 diabetes.
More broadly, they write that the condition should be considered in lean individuals with metabolic diseases, such as type 2 diabetes, dyslipidemia, and hypertension, as well as elevated values on liver biochemical tests or incidentally noted hepatic steatosis.
After other causes of liver diseases are ruled out, the authors note that clinicians should consider liver biopsy as the reference test if uncertainties remain about liver injury causes and/or liver fibrosis staging.
They also write that the NAFLD fibrosis score and Fibrosis-4 score, along with imaging techniques, may be used as alternatives to biopsy for staging and during follow-up.
The authors, who provide a diagnosis and management algorithm to aid clinicians, suggest that lean patients with NAFLD follow lifestyle interventions, such as exercise, diet modification, and avoidance of fructose- and sugar-sweetened drinks, to achieve weight loss of 3%-5%.
Vitamin E may be considered, they continue, in patients with biopsy-confirmed nonalcoholic steatohepatitis but without type 2 diabetes or cirrhosis. Additionally, oral pioglitazone may be considered in lean persons with biopsy-confirmed nonalcoholic steatohepatitis without cirrhosis.
In contrast, they write that the role of glucagonlike peptide 1 agonists and sodium-glucose cotransporter 2 inhibitors requires further investigation.
The advice also says that lean patients with NAFLD should be routinely evaluated for comorbid conditions, such as type 2 diabetes, dyslipidemia, and hypertension, and risk-stratified for hepatic fibrosis to identify those with advanced fibrosis or cirrhosis.
For lean patients with NAFLD and clinical markers compatible with liver cirrhosis, twice-yearly surveillance for hepatocellular carcinoma is also advised.
Fatty liver disease in lean people with metabolic conditions
Approached for comment, Liyun Yuan, MD, PhD, assistant professor of clinical medicine, University of Southern California, Los Angeles, said it is very important to have uniform guidelines for general practitioners and other specialties on NAFLD in lean individuals.
Dr. Yuan, who was not involved in the review, told this news organization that it is crucial to raise awareness of NAFLD, just like awareness of breast cancer screening among women of a certain age was increased, so that individuals are screened for metabolic conditions regardless of whether they have obesity or overweight.
Zobair Younossi, MD, MPH, professor of medicine, Virginia Commonwealth University, Inova Campus, Falls Church, Va., added that there is a lack of awareness that NAFLD occurs in lean individuals, especially in those who have diabetes.
He said in an interview that although it is accurate to define individuals as being lean in terms of their BMI, the best way is to look not only at BMI but also at waist circumference.
Dr. Younossi said that he and his colleagues have shown that when BMI is combined with waist circumference, the prediction of mortality risk in NAFLD is affected, such that lean individuals with an obese waist circumference have a higher risk for all-cause mortality.
Dr. Long is supported in part by the National Institute of Diabetes and Digestive and Kidney Diseases, Doris Duke Charitable Foundation, Gilead Sciences Research Scholars Award, Boston University School of Medicine Department of Medicine Career Investment Award, and Boston University Clinical Translational Science Institute. Dr. Long declares relationships with Novo Nordisk, Echosens Corporation, and Gilead Sciences. Dr. Yuan declares relationships with Genfit, Intercept, and Gilead Sciences. Dr. Younossi declares no relevant relationships.

Vitamin E may be considered, they continue, in patients with biopsy-confirmed nonalcoholic steatohepatitis but without type 2 diabetes or cirrhosis. Additionally, oral pioglitazone may be considered in lean persons with biopsy-confirmed nonalcoholic steatohepatitis without cirrhosis.
In contrast, they write that the role of glucagonlike peptide 1 agonists and sodium-glucose cotransporter 2 inhibitors requires further investigation.
The advice also says that lean patients with NAFLD should be routinely evaluated for comorbid conditions, such as type 2 diabetes, dyslipidemia, and hypertension, and risk-stratified for hepatic fibrosis to identify those with advanced fibrosis or cirrhosis.
For lean patients with NAFLD and clinical markers compatible with liver cirrhosis, twice-yearly surveillance for hepatocellular carcinoma is also advised.
Fatty liver disease in lean people with metabolic conditions
Approached for comment, Liyun Yuan, MD, PhD, assistant professor of clinical medicine, University of Southern California, Los Angeles, said it is very important to have uniform guidelines for general practitioners and other specialties on NAFLD in lean individuals.
Dr. Yuan, who was not involved in the review, told this news organization that it is crucial to raise awareness of NAFLD, just like awareness of breast cancer screening among women of a certain age was increased, so that individuals are screened for metabolic conditions regardless of whether they have obesity or overweight.
Zobair Younossi, MD, MPH, professor of medicine, Virginia Commonwealth University, Inova Campus, Falls Church, Va., added that there is a lack of awareness that NAFLD occurs in lean individuals, especially in those who have diabetes.
He said in an interview that although it is accurate to define individuals as being lean in terms of their BMI, the best way is to look not only at BMI but also at waist circumference.
Dr. Younossi said that he and his colleagues have shown that when BMI is combined with waist circumference, the prediction of mortality risk in NAFLD is affected, such that lean individuals with an obese waist circumference have a higher risk for all-cause mortality.

Ongoing follow-up and lifestyle interventions are needed in lean patients with nonalcoholic fatty liver disease (NAFLD), suggests a panel of experts in a recent review.
They also urge screening for NAFLD in individuals who are older than 40 years with type 2 diabetes, even if they are not overweight.
NAFLD is a leading cause of chronic liver disease that affects more than 25% of the United States and worldwide populations, note lead author Michelle T. Long, MD, Boston Medical Center, Boston University, and colleagues.
They add that around one-quarter of those affected have nonalcoholic steatohepatitis, which is associated with significant morbidity and mortality due to complications of liver cirrhosis, hepatic decompensation, and hepatocellular carcinoma.
Although NAFLD occurs primarily in individuals with obesity or type 2 diabetes, between 7%-20% have a lean body habitus, they write.
There are differences in rates of disease progression, associated conditions, and diagnostic and management approaches between lean and non-lean patients, the authors note, but there is limited guidance on the appropriate clinical evaluation of the former group.
The American Gastroenterological Association therefore commissioned an expert review to provide best practice advice on key clinical issues relating to the diagnosis, risk stratification, and treatment of NAFLD in lean individuals.
Their review was published online in Gastroenterology.
Evidence-based approaches
The 15 best practice advice statements covered a wide range of clinical areas, first defining lean as a body mass index (BMI) less than 25 in non-Asian persons and less than 23 in Asian persons.
The authors go on to stipulate, for example, that lean individuals in the general population should not be screened for NAFLD but that screening should be considered for individuals older than 40 years with type 2 diabetes.
More broadly, they write that the condition should be considered in lean individuals with metabolic diseases, such as type 2 diabetes, dyslipidemia, and hypertension, as well as elevated values on liver biochemical tests or incidentally noted hepatic steatosis.
After other causes of liver diseases are ruled out, the authors note that clinicians should consider liver biopsy as the reference test if uncertainties remain about liver injury causes and/or liver fibrosis staging.
They also write that the NAFLD fibrosis score and Fibrosis-4 score, along with imaging techniques, may be used as alternatives to biopsy for staging and during follow-up.
The authors, who provide a diagnosis and management algorithm to aid clinicians, suggest that lean patients with NAFLD follow lifestyle interventions, such as exercise, diet modification, and avoidance of fructose- and sugar-sweetened drinks, to achieve weight loss of 3%-5%.
Vitamin E may be considered, they continue, in patients with biopsy-confirmed nonalcoholic steatohepatitis but without type 2 diabetes or cirrhosis. Additionally, oral pioglitazone may be considered in lean persons with biopsy-confirmed nonalcoholic steatohepatitis without cirrhosis.
In contrast, they write that the role of glucagonlike peptide 1 agonists and sodium-glucose cotransporter 2 inhibitors requires further investigation.
The advice also says that lean patients with NAFLD should be routinely evaluated for comorbid conditions, such as type 2 diabetes, dyslipidemia, and hypertension, and risk-stratified for hepatic fibrosis to identify those with advanced fibrosis or cirrhosis.
For lean patients with NAFLD and clinical markers compatible with liver cirrhosis, twice-yearly surveillance for hepatocellular carcinoma is also advised.

‘Alarming’ global rise in NAFLD
The global prevalence of fatty liver disease not caused by alcohol is considerably higher than previously estimated and is continuing to increase at an alarming rate, report researchers from Canada.
Their analysis suggests nearly one-third of the global general adult population has nonalcoholic fatty liver disease (NAFLD), with men much more likely to have the disease than women.
“Greater awareness of NAFLD and the development of cost-effective risk stratification strategies are needed to address the growing burden NAFLD,” wrote Abdel-Aziz Shaheen, MBBCh, MSc, and colleagues with the University of Calgary (Alta.).
The study was published online in Lancet Gastroenterology and Hepatology.
NAFLD is the most common liver disease worldwide and a leading cause of liver-related illness and death. Yet, high-quality reports on the epidemiology of NAFLD at a global level are scarce and temporal trends of the NAFLD burden, including by gender, have not been described, until now.
Using MEDLINE, EMBASE, Scopus, and Web of Science, the Calgary team identified reports on NAFLD incidence and prevalence in study populations representative of the general adult population published between the date of database inception to May 25, 2021.
In total, 72 publications, with a sample population of more than 1 million adults from 17 countries, were included in the prevalence analysis, and 16 publications, with a sample population of nearly 382,000 individuals from five countries, were included in the incidence analysis.
By their estimates, the overall global prevalence of NAFLD is 32.4%, with prevalence increasing steadily and significantly over time, from 25.5% in or before 2005 to 37.8% in 2016 or later. The overall prevalence is significantly higher in men than in women (39.7% vs. 25.6%).
These figures contrast with recent meta-analyses and systematic reviews that put the global prevalence of NAFLD at between 25.2% and 29.8%. However, these studies had “considerable” limitations with “potentially biased inferences,” Dr. Shaheen and colleagues noted.
By region, their data put the prevalence of NAFLD at 31.6% in Asia, 32.6% in Europe, 47.8% in North America, and 56.8% in Africa.
Dr. Shaheen and colleagues estimate the overall incidence of NAFLD to be 46.9 cases per 1,000 person-years, with a higher incidence in men than women (70.8 vs. 29.6 cases per 1000 person-years), in line with the gender differences in prevalence.
They caution that there was “considerable” heterogeneity between studies in both NAFLD prevalence and incidence (I2 = 99.9%) and few “high-quality” studies.
Despite these limitations, Dr. Shaheen and colleagues said the rise in NAFLD prevalence “should drive enhanced awareness of NAFLD at the level of primary care physicians, public health specialists, and health policy makers to encourage the development of more effective preventive policies.”
Funding for the study was provided by the Canadian Institutes of Health. Dr. Shaheen has received research grants from Gilead and Intercept, and honoraria from SCOPE Canada.

FROM LANCET GASTROENTEROLOGY AND HEPATOLOGY
Prior decompensation in alcohol-associated hepatitis not an ‘absolute contraindication’ for early liver transplant
Past decompensation in alcohol-associated hepatitis may be linked with worse survival following liver transplantation, but it’s not all bad news, according to a retrospective study.
Traditionally, patients with alcoholic liver disease were asked to be alcohol free for 6 months before consideration for a liver transplantation. In recent years, there’s been a loosening of that policy, with physicians considering “early” liver transplantation (early LT) instead of waiting 6 months. “It became obvious that a lot of patients do resume alcohol use after transplant, and most of them don’t appear to suffer too much in the way of adverse consequences,” said Paul Martin, MD, chief of hepatology at the University of Miami, who was not involved in the current research.
In 2011, a study confirmed that suspicion, finding that 6-month survival was 77% among carefully selected patients with alcohol-associated hepatitis for whom the 6-month sobriety requirement was waived; 6-month survival in those who did not receive a transplant was 22%. The selection criteria included the presence of supportive family members, the absence of severe coexisting conditions, and a commitment to abstaining from alcohol.
However, authors of the current study, published in the American Journal of Gastroenterology sought nuance: The appropriateness of prior decompensation as exclusion criteria in published studies is unknown, so the researchers compared outcomes of patients with prior versus first-time liver decompensation in alcohol-associated hepatitis.
Not all bad news
The study included 241 patients from six sites who consecutively received early LT between 2007 and 2020. Among these, 210 were identified as having a first-time liver decompensation event and 31 as having had a prior history of liver decompensation, defined as being diagnosed with ascites, hepatic encephalopathy, variceal bleeding, or jaundice.
There was no significant difference in median age, Model for End-Stage Liver Disease (MELD) scores, or post–liver transplant follow-up time between those with first-time liver decompensation or a prior history. The unadjusted 1-year survival rate was 93% in the first decompensation group (95% confidence interval, 89%-96%) and 86% in the prior decompensation group (95% CI, 66%-94%). The unadjusted 3-year survival rates were 85% (95% CI, 79%-90%) and 78% (95% CI, 57%-89%), respectively.
Importantly, the researchers found an association between prior decompensation and higher adjusted post–liver transplantation mortality (adjusted hazard ratio, 2.72; 95% CI, 1.61-4.59) and harmful alcohol use (aHR, 1.77; 95% CI, 1.07-2.92).
However, the researchers noted that these patients, who had MELD scores of 39 and previous decompensation, were at exceptionally high risk of short-term mortality, but still had 1- and 3-year survival rates above 85% and 75%, respectively, with early LT. “While longer follow-up is desirable as graft failure related to alcohol is most apparent after 5-years post LT, these results suggest that prior decompensation alone should not be considered an absolute contraindication to early LT.”
Limitations of the study included its retrospective data and small sample size for patients with prior decompensation.
“These findings validate the value of the ‘first decompensation’ criteria in published experiences regarding early LT for [alcoholic hepatitis],” the investigators concluded. “Further larger and prospective studies with longer-term follow-up will be needed to assess ways to optimally select patients in this cohort who may benefit most from early LT, and ways to manage patients at highest risk for worse outcomes post LT.”
A note of caution for early LT
About half of all liver mortality is attributable to alcoholic-associated liver disease. Corticosteroids can improve short-term survival, but there are no medications proven to increase long-term survival. That leaves liver transplant as the sole alternative for patients who don’t respond to corticosteroids.
“Programs in North America have liberalized their acceptance criteria for patients with alcoholic liver disease, and that’s resulted in large numbers of patients being transplanted who have less than 6 months abstinence. And overall, the results seem good, but I think this paper strikes an appropriate note of caution. In essence, if a patient had at least one prior episode of liver failure related to alcoholic excess and had recovered from that, and continued to drink and got into trouble again, [and then] presented for consideration for liver transplantation, the fact that they resumed alcohol use after prior episodes of decompensation suggests that they may be less-than-ideal candidates [for liver transplantation],” said Dr. Martin.
He pointed out important caveats to the study, including its retrospective nature and its inclusion of a relatively small number of patients with a history of liver decompensation. But it reinforces what physicians generally know, which is that some patients with severe alcohol use disorder also have liver failure, and they tend to fare worse than others after a liver transplant.
Still, physicians also face a conundrum because there are increasing numbers of younger patients who won’t survive if they don’t get a liver transplant. “The challenge is picking out patients who are going to be good candidates from a purely medical point of view, but have a low likelihood of resuming alcohol use after transplantation [which could injure] the new liver,” said Dr. Martin. The new study has the potential to provide some additional guidance in patient selection.
The study authors disclosed no relevant conflicts of interest. Dr. Martin has no relevant financial disclosures.

FROM THE AMERICAN JOURNAL OF GASTROENTEROLOGY
Liver cancer risk persists after direct-acting antiviral treatment for HCV
, according to a new report.
Among patients with cirrhosis and fibrosis-4 (FIB-4) scores of 3.25 or higher, the incidence of hepatocellular carcinoma appeared to decline progressively each year up to 7 years after a sustained virologic response, although the rate remained above the 1% per year threshold that warrants screening.
“The majority of patients with hepatitis C have been treated and cured in the United States,” George Ioannou, MD, the senior study author and professor of medicine at the University of Washington, Seattle, said in an interview. “After hepatitis C eradication, these patients generally do very well from the liver standpoint, but the one thing they have to continue worrying about is development of liver cancer.”
Dr. Ioannou, who is also director of hepatology at the Veterans Affairs Puget Sound Health Care System, Seattle, noted that patients may be screened “indefinitely,” which places a burden on the patients and the health care system.
“We are still not sure to what extent the risk of liver cancer declines after hepatitis C eradication as more and more time accrues,” he said. “In those who had cirrhosis of the liver prior to hepatitis C cure, we are still not certain if there is a time point after hepatitis C cure when we can tell a patient that their risk of liver cancer is now very low and we no longer need to keep screening for liver cancer.”

In a previous study, Dr. Ioannou and colleagues found that hepatocellular carcinoma risk declined during the first 4 years of follow-up after a sustained virologic response from direct-acting antiviral medications. But the follow-up time wasn’t long enough to determine whether the cancer risk continues to decline to levels low enough to forgo screening.
In this study, Dr. Ioannou and colleagues extended the follow-up to 7 years. They were curious to see whether the cancer risk declines enough to drop the screening requirement, particularly as related to pretreatment cirrhosis and fibrosis-4 scores.
The research team analyzed electronic health records from the Veterans Affairs Corporate Data Warehouse, a national repository of Veterans Health Administration records developed specifically for research purposes.
The researchers included 29,033 patients in the Veterans Affairs health care system who had been infected with hepatitis C virus and were treated with direct-acting antivirals between January 2013 and December 2015. The patients had a sustained virologic response, which is defined as a viral load below the lower limit of detection at least 12 weeks after therapy completion.
The patients were followed for incident hepatocellular carcinoma until December 2021. The researchers then calculated the annual incidence during each year of follow-up after treatment.
About 96.6% of patients were men, and 52.2% were non-Hispanic White persons. The average age was 61 years. The most common conditions were alcohol use disorder (43.7%), substance use disorder (37.7%), and diabetes (28.9%).
Among the 7,533 patients with pretreatment cirrhosis, 948 (12.6%) developed hepatocellular carcinoma during a mean follow-up period of 4.9 years. Among patients with FIB-4 scores of 3.25 or higher, the annual incidence decreased from 3.8% in the first year to 1.4% in the seventh year but remained substantial up to 7 years after sustained virologic response. Among patients with both cirrhosis and a high FIB-4 score, the annual rate ranged from 0.7% to 1.3% and didn’t change significantly over time.
Among the 21,500 patients without pretreatment cirrhosis, 541 (or 2.5%) developed hepatocellular carcinoma during a mean follow-up period of 5.4 years. The incidence rate was significantly higher for patients with high FIB-4 scores. Among patients without cirrhosis but who had a high FIB-4 score, the annual rate remained stable but substantial (from 0.8% to 1.3%) for up to 7 years.
In a subgroup analysis that examined incidence according to changes in FIB-4 scores before and after treatment, the rate remained high among those with cirrhosis regardless of a score change. Among those without cirrhosis but who had a persistently high FIB-4 score, the incidence was high. In those without cirrhosis whose FIB-4 score dropped, the incidence was lower.
“The study demonstrates a clear decline in the risk of liver cancer over time after hepatitis C cure in the highest-risk group. This is very positive news for patients,” Dr. Ioannou said. “However, even with that decline in risk up to 7 years after eradication of hepatitis C with direct-acting antivirals, the risk is still high enough to warrant liver cancer screening.”
Future concerns
For a follow-up study, Dr. Ioannou and colleagues plan to adjust their analyses for other factors that influence the risk of liver cancer, such as age and nonalcoholic fatty liver disease. Other studies could increase the follow-up time beyond 7 years and assess how changes in diabetes, weight management, and alcohol use might affect liver cancer risk.
“With the availability of safe and effective direct-acting antiviral treatments, a growing number of patients have been or will be treated and cured of their hepatitis C infection,” Nicole Kim, MD, one of the lead authors and a transplant hepatology fellow at the University of Washington, Seattle, told this news organization.
“It is therefore important for us to develop a better understanding of how liver cancer risk might change after treatment, so we can improve the care we provide to this patient population,” she said.
The results require validation in nonveteran cohorts, the study authors write, as well as follow-up after the COVID-19 pandemic, when screening and diagnostic practices were restricted.
“Several studies have demonstrated that HCC [hepatocellular carcinoma] surveillance is underused in clinical practice, including in patients after [sustained virologic response],” Amit Singal, MD, clinical chief of hepatology and medical director of the liver tumor program at the University of Texas Southwestern Medical Center, told this news organization.
Dr. Singal, who wasn’t involved with this study, is evaluating several intervention strategies to increase surveillance utilization. His research group is conducting a multicenter randomized trial using mailed outreach invitations and is also evaluating a biomarker, PLSec-AFP, to identify patients with the highest risks who may warrant more intensive surveillance strategies.
“We have recently validated the performance of this biomarker in a large cohort of patients with cirrhosis, including some with cured hepatitis C virus infection,” he said.
The study was funded by an NIH/NCI grant and a VA CSR under Dr. Ioannou. The manuscript writing was supported by the NIH under Dr. Kim and co-author Philip Vutien. Dr. Singal has disclosed no relevant financial relationships.

Among patients with cirrhosis and fibrosis-4 (FIB-4) scores of 3.25 or higher, the incidence of hepatocellular carcinoma appeared to decline progressively each year up to 7 years after a sustained virologic response, although the rate remained above the 1% per year threshold that warrants screening.
“The majority of patients with hepatitis C have been treated and cured in the United States,” George Ioannou, MD, the senior study author and professor of medicine at the University of Washington, Seattle, said in an interview. “After hepatitis C eradication, these patients generally do very well from the liver standpoint, but the one thing they have to continue worrying about is development of liver cancer.”
Dr. Ioannou, who is also director of hepatology at the Veterans Affairs Puget Sound Health Care System, Seattle, noted that patients may be screened “indefinitely,” which places a burden on the patients and the health care system.
“We are still not sure to what extent the risk of liver cancer declines after hepatitis C eradication as more and more time accrues,” he said. “In those who had cirrhosis of the liver prior to hepatitis C cure, we are still not certain if there is a time point after hepatitis C cure when we can tell a patient that their risk of liver cancer is now very low and we no longer need to keep screening for liver cancer.”

Link between pediatric hepatitis and adenovirus 41 still unclear
While two new studies reiterate a possible relationship between adenovirus 41 and acute hepatitis of unknown cause in children, whether these infections are significant or merely bystanders remains unclear.
In both studies – one conducted in Alabama and the other conducted in the United Kingdom – researchers found that 90% of children with acute hepatitis of unknown cause tested positive for adenovirus 41. The virus subtype is not an uncommon infection, but it usually causes gastroenteritis in children.
“Across the world, adenovirus continues to be a common signal” in these pediatric hepatitis cases, said Helena Gutierrez, MD, the medical director of the Pediatric Liver Transplant Program at the University of Alabama at Birmingham, in an interview. She led one of the studies. More data are necessary to understand what role this virus may play in these cases, she said.
In November, the Alabama Department of Public Health and the U.S. Centers for Disease Control and Prevention began investigating a cluster of severe pediatric hepatitis cases at the Children’s of Alabama hospital in Birmingham. These children also tested positive for adenovirus. In April, the United Kingdom announced they were investigating similar cases, and the CDC expanded their search nationally. As of July 8, 1,010 cases in 35 countries have been reported to the World Health Organization. There are 263 confirmed cases in the United Kingdom and 332 cases under investigation by the CDC in the United States, according to the most recent counts.
The two studies, both published in the New England Journal of Medicine, provide additional clinical data on a number of these mysterious hepatitis cases. Dr. Gutierrez’s study looked at nine children admitted for hepatitis of unknown origin between October 1 and February 28. Patients had a median age of 2 years 11 months and two required liver transplants, and there were no deaths.
Eight out of nine patients (89%) tested positive for adenovirus, and all five of the samples that were of sufficient quality for gene sequencing tested positive for adenovirus 41. None of the six liver biopsies performed found signs of adenovirus infection, but the liver tissue samples of three patients tested positive for adenovirus via PCR.
The second study involved 44 children referred to a liver transplantation center in the United Kingdom between January 1 and April 11, 2022. The median age for patients was 4 years. Six children required liver transplants, and there were no deaths. Of the 30 patients who underwent molecular adenovirus testing, 27 (90%) were positive for adenovirus 41. Liver samples of nine children (3 from biopsies and 6 from explanted livers) all tested negative for adenovirus antibodies.
In both studies, however, the median adenovirus viral load of patients needing a transplant was much higher than the viral loads in children who did not require liver transplants.
Although most of the clinical features and test results of these cases suggest that adenovirus may be involved, the negative results in histology are “intriguing,” Chayarani Kelgeri, MD, a consultant pediatric hepatologist at the Birmingham Women’s and Children’s Hospital, U.K., said in an email. She is the lead author of the U.K. study. “Whether this is because the liver injury we see is an aftermath of the viral infection, the mechanism of injury is immune mediated, and if other cofactors are involved is being explored,” she added. “Further investigations being undertaken by UK Health Security Agency will add to our understanding of this illness.”
Although there is a high adenovirus positivity rate amongst these cases, there is not enough evidence yet to say adenovirus 41 is a new cause of pediatric hepatitis in previously healthy children, said Saul Karpen, MD, PhD, the division chief of pediatric gastroenterology, hepatology, and nutrition at Emory University School of Medicine, Atlanta. He wrote an editorial accompanying the two NEJM studies.
The CDC has not yet found an increase in pediatric hepatitis cases, according to a recent analysis, though the United Kingdom has found an uptick in cases this year, he told this news organization. Also, the cases highlighted in both articles showed no histological evidence of adenovirus in liver biopsies. “That’s completely opposite of what we generally see in adenoviral hepatitis that can be quite severe,” he said, adding that in general, there are detectable viral particles and antigens in affected livers.
“These two important reports indicate to those inside and outside the field of pediatric hepatology that registries and clinical studies of acute hepatitis in children are sorely needed,” Dr. Karpen writes in the editorial; “It is likely that with greater attention to collecting data on cases and biospecimens from children with acute hepatitis, we will be able to determine whether this one virus, human adenovirus 41, is of relevance to this important and serious condition in children.”
Dr. Gutierrez, Dr. Kelgeri, and Dr. Karpen report no relevant financial relationships.

New insights into worldwide biliary tract cancer incidence, mortality
Incidence and mortality for biliary tract cancer (BTC) are both on the rise worldwide, according to a new analysis of data from the International Agency for Research on Cancer and the World Health Organization.
This diverse group of hepatic and perihepatic cancers include gallbladder cancer (GBC), intrahepatic and extrahepatic cholangiocarcinoma (ICC and ECC), and ampulla of Vater cancer. Although BTC is considered rare, incidence of its subtypes can vary significantly by geographic region. Because BTC is typically asymptomatic in its early stage, diagnosis is often made after tumors have spread, when there are few therapeutic options available. In the United States and Europe, 5-year survival is less than 20%.
Although previous studies have examined worldwide BTC incidence, few looked at multiple global regions or at all subtypes. Instead, subtypes may be grouped together and reported as composites, or BTC is lumped together with primary liver cancer. “To our knowledge, this is the first report combining data on worldwide incidence and mortality of all BTC subtypes per the International Classification of Diseases, Tenth Revision,” the authors wrote in the study, published online in Gastro Hep Advances.
The researchers pointed out that classification coding systems have improved at defining BTC subtypes, so that studies using older coding subtypes could cause misinterpretation of incidence rates.
BTC subtypes also have unique sets of risk factors and different prognoses and treatment outcomes. “Thus, there is a need to define accurate epidemiologic trends that will allow specific risk factors to be identified, guiding experts in implementing policies to improve diagnosis and survival,” the authors wrote.
The study included data from 22 countries. BTC incidence ranged from 1.12 cases per 100,000 person-years in Vietnam to 12.42 in Chile. As expected, incidence rates were higher in the Asia-Pacific region (1.12-9.00) and South America (2.73-12.42), compared with Europe (2.00-3.59) and North America (2.33-2.35). Within the United States, Asian Americans had a higher BTC incidence than the general population (2.99 vs. 2.33).
In most countries, new cases were dominated by GBC, while ICC was the most common cause of death.
In each country, older patients were 5-10 times more likely to die than BTC patients generally. The sixth and seventh decades of life are the most common time of diagnosis, and treatment options may be limited in older patients.
Risk factors for BTC may include common comorbidities like obesity, nonalcoholic fatty liver disease, and diabetes. Each is increasing individually, which may in turn contribute to rising BTC incidence. Observational analyses suggest that obesity may contribute to risk of ECC and gallbladder cancer, while diabetes and obesity may raise the risk of ICC. Smoking is associated with increased risk of all BTC subtypes except GBC, and alcohol consumption is associated with ICC.
“This study highlights how each subtype may be vulnerable to specific risk factors and emphasizes the value of separating epidemiologic data by subtype in order to better understand disease etiology,” the researchers wrote.
Risk factors associated with incidence and mortality from BTC aren’t limited to clinical characteristics. Genetic susceptibility may also play a role in incidence and mortality of different subtypes. There is also a relationship between gallstones and BTC risk. In Chile, about 50% of women have gallstones versus 17% of women in the United States. The cancer incidence is 27 per 100,000 person-years in Chile and 2 per 100,000 person-years in the United States. BTC is also the leading cause of cancer death among women in Chile.
The authors also highlighted the high rates of gallbladder cancer in India, despite a low prevalence of gallstones. Incidences can vary with geography along the flow of the Ganges River, which might reflect varying risks from contamination caused by agricultural runoff or industrial or human waste.
Worldwide BTC incidence and mortality was generally higher among women than men, with the exception of ampulla of Vater cancer, which was more common in men.
The study is limited by quality of data, which varied significantly between countries. Mortality data was missing from some countries know to have high BTC incidence. The databases had little survival data, which could have provided insights into treatment efficacy.
The study was funded by AstraZeneca. The authors have extensive financial relationships with pharmaceutical companies.
Biliary tract cancers (BTCs) are understudied malignancies with poor prognoses. A major impediment to a deeper understanding of BTC epidemiology is that the term BTC encompasses a heterogeneous group of cancers including cholangiocarcinoma (both intrahepatic and extrahepatic), as well as ampullary and gallbladder cancer. Studies have often lumped all BTC subgroups together despite differences in their geographic distribution, risk factors, and underlying pathogenesis. Furthermore, epidemiological reporting has often grouped “intrahepatic liver and bile duct cancers” which include hepatocellular carcinoma, a biologically different entity requiring a separate management strategy.
This study by Baria et al. takes the important next step of analyzing BTC incidence and mortality at a worldwide level while providing granular data on geographic variations in BTC subtypes. The most notable finding is the increasing incidence and mortality of BTCs in most countries studied, the latter of which is possibly driven by intrahepatic cholangiocarcinoma’s particularly poor prognosis. The high rates of BTC incidence and mortality in Asian countries may be driven by cholangiocarcinoma and its known risk factors including chronic hepatitis B and C viruses and liver fluke infection. Future drivers of incidence will likely include metabolic syndrome.
The study highlights the importance of future policy work to address the risk factors for BTCs that vary by region and that will likely evolve over time. It also stresses the urgent need for both early diagnostic strategies and improved biomarker-driven medical therapy, areas of ongoing research requiring accelerated development.

Incidence and mortality for biliary tract cancer (BTC) are both on the rise worldwide, according to a new analysis of data from the International Agency for Research on Cancer and the World Health Organization.
This diverse group of hepatic and perihepatic cancers include gallbladder cancer (GBC), intrahepatic and extrahepatic cholangiocarcinoma (ICC and ECC), and ampulla of Vater cancer. Although BTC is considered rare, incidence of its subtypes can vary significantly by geographic region. Because BTC is typically asymptomatic in its early stage, diagnosis is often made after tumors have spread, when there are few therapeutic options available. In the United States and Europe, 5-year survival is less than 20%.
Although previous studies have examined worldwide BTC incidence, few looked at multiple global regions or at all subtypes. Instead, subtypes may be grouped together and reported as composites, or BTC is lumped together with primary liver cancer. “To our knowledge, this is the first report combining data on worldwide incidence and mortality of all BTC subtypes per the International Classification of Diseases, Tenth Revision,” the authors wrote in the study, published online in Gastro Hep Advances.
The researchers pointed out that classification coding systems have improved at defining BTC subtypes, so that studies using older coding subtypes could cause misinterpretation of incidence rates.
BTC subtypes also have unique sets of risk factors and different prognoses and treatment outcomes. “Thus, there is a need to define accurate epidemiologic trends that will allow specific risk factors to be identified, guiding experts in implementing policies to improve diagnosis and survival,” the authors wrote.
The study included data from 22 countries. BTC incidence ranged from 1.12 cases per 100,000 person-years in Vietnam to 12.42 in Chile. As expected, incidence rates were higher in the Asia-Pacific region (1.12-9.00) and South America (2.73-12.42), compared with Europe (2.00-3.59) and North America (2.33-2.35). Within the United States, Asian Americans had a higher BTC incidence than the general population (2.99 vs. 2.33).
In most countries, new cases were dominated by GBC, while ICC was the most common cause of death.
In each country, older patients were 5-10 times more likely to die than BTC patients generally. The sixth and seventh decades of life are the most common time of diagnosis, and treatment options may be limited in older patients.
Risk factors for BTC may include common comorbidities like obesity, nonalcoholic fatty liver disease, and diabetes. Each is increasing individually, which may in turn contribute to rising BTC incidence. Observational analyses suggest that obesity may contribute to risk of ECC and gallbladder cancer, while diabetes and obesity may raise the risk of ICC. Smoking is associated with increased risk of all BTC subtypes except GBC, and alcohol consumption is associated with ICC.

Bulevirtide reduces hepatitis D viral load in difficult-to-treat patients
Bulevirtide (Hepcludex) monotherapy significantly reduces the load of hepatitis delta virus (HDV) and is safe in difficult-to-treat patients with compensated cirrhosis and clinically significant portal hypertension, according to the results of an ongoing 1-year study.
In presenting a poster with these findings at the annual International Liver Congress, sponsored by the European Association for the Study of the Liver, lead author Elisabetta Degasperi, MD, from the Grand Hospital Maggiore Policlinico in Milan, said that they were important “because they confirm the safety of this drug in real life.”
Dr. Degasperi and colleagues showed that bulevirtide leads to a significant viral response in 78% of patients by week 48, which was measured using the outcome of greater than 2 log decline in HDV RNA from baseline.
Dr. Degasperi added that the research still needed to assess the longer-term benefits, but
Addressing an immense, unmet therapeutic need
HDV requires the presence of hepatitis B virus to replicate. Bulevirtide blocks the entry of HDV and hepatitis B virus into hepatocytes.
In July 2020, it was conditionally approved in the European Economic Area for use to treat chronic HDV infection in adults with compensated liver disease upon confirmation of HDV RNA in the blood. It currently remains an investigational agent in the United States, as well as outside of the EEA.
The ongoing trial led by Dr. Degasperi is specifically conducted in patients with compensated cirrhosis who also have clinically significant portal hypertension, where safety and efficacy are unknown.
Dr. Degasperi said in an interview that, although HDV was rare, there is nonetheless an “immense” need for effective therapies against it, especially in young patients with advanced liver disease.
“We have a lot of patients with hepatitis D who have not responded to other antiviral treatment. Right now, the only other available treatment is pegylated interferon,” she said. “Unfortunately, rates of sustained viral response to pegylated interferon are extremely low at around 30% of patients.”
Chronic HDV is the most severe form of viral hepatitis and can have mortality rates as high as 50% within 5 years in patients with cirrhosis.
The management of hepatitis D is also complicated by the fact that patients with advanced cirrhosis and clinically significant portal hypertension cannot be treated with pegylated interferon owing to lack of efficacy and safety reasons, including a high risk for decompensation and liver-related complications. Pegylated interferon is contraindicated in these patients.
Bulevirtide at 48 weeks: A closer look at the findings
Eighteen patients with HDV, compensated cirrhosis, and clinically significant portal hypertension were consecutively enrolled in this single-center, longitudinal study.
All received bulevirtide monotherapy at 2 mg/day and underwent monitoring every 2 months. They were also treated with nucleotide analogs for their hepatitis B virus, which was suppressed when they began bulevirtide.
Clinical and virologic characteristics were collected at baseline, at weeks 4 and 8, and then every 8 weeks thereafter.
Bulevirtide led to a significant viral response such that by week 48, HDV RNA declined by 3.1 log IU/mL (range, 0.2-4.6 log IU/mL), was undetectable in six patients (33%), and was less than 100 IU/L in 50% of patients. Two patients were nonresponders. In addition, 78% of patients achieved at least an HDV RNA 2 log decline from baseline.
There was also a normalization of biochemical response in the majority of patients.
Alanine aminotransferase normalization was seen in 89% of patients and declined by a median of 34 U/L (range, 15-76 U/L) over 48 weeks. Aspartate aminotransferase declined to 39 U/L (range, 21-92 U/L). A combined response was seen in 72% of patients, reported Dr. Degasperi.
“Previously, we only had results from a phase 2 study, so we had no idea of the results over such a long treatment period,” said Dr. Degasperi. “It is also the first time we have been able to treat these patients with such advanced disease that is so difficult to manage.”
“Real-world results are typically inferior to those from clinical trials, but the viral decline is comparable to phase 2 trials, and the first report of the phase 3 trial,” said Dr. Degasperi.
Gamma-glutamyltransferase, alpha-fetoprotein, immunoglobulin G, and gamma-globulin levels also improved, whereas hepatitis B surface antigen, hepatitis B virus RNA, hepatitis B core-related antigen, platelet, and bilirubin values did not significantly change.
“All patients were Child-Pugh score A, so well-compensated [disease]. However, they increased a little bit in liver function by week 48,” Dr. Degasperi said. “This was important for this very advanced disease population.”
She added that the safety profile was very favorable, with no adverse events, including no injection-site reactions.
There was an asymptomatic increase in serum bile acids. “No patients complained about itching or pruritus,” Dr. Degasperi said.
What’s ahead for bulevirtide?
In a comment, Marc Bourlière, MD, from Saint Joseph Hospital in Marseilles, France, welcomed the decrease in viral load.
“This is known to be beneficial in terms of reducing morbidity and mortality in hepatitis D,” he said. “Remember that this disease is very difficult to treat, and until now, we have had no drug available. Pegylated interferon achieves cure in only 30% of patients, and half of these relapse, so actually only 15% have a meaningful response from pegylated interferon.”
“The main issue is its use as a daily subcutaneous injection. In clinical practice, it is a little bit complicated to set up, but once done, it is quite well accepted,” he said.
“I’m impressed with these results to date because there are no other compounds that have, as yet, achieved such results. This is impressive,” he added. “But whether it translates into a long-term response we don’t yet know.”
Dr. Bourlière also noted the meaningful 2-point log decline, noting that “HDV RNA negativity where treatment can be stopped would be really meaningful, but this endpoint is hard to obtain.”
Dr. Bourlière is awaiting results of the current ongoing phase 2/3 study, which would help determine a possible final treatment duration. He is also curious to settle the ongoing debate about whether bulevirtide should be used alone or in combination.
“We need to combine bulevirtide with pegylated interferon in less-advanced patients, because we know it is more potent and active against the HDV RNA,” he said.
Dr. Degasperi has previously declared she was on the advisory board for AbbVie and has spoken and taught for Gilead, MSD, and AbbVie. Dr. Bourlière declared interests with all companies involved in the R&D of liver therapies.
