AI Tool Identifies Undiagnosed Early-Stage MASLD
SAN DIEGO — according to new research.
Among the patients identified by the algorithm as meeting the criteria for MASLD, only a small percentage had an MASLD-associated diagnostic code.
“A significant portion of patients who meet criteria for MASLD go undiagnosed, which can lead to delays in care and progression to advanced liver disease,” said lead author Ariana Stuart, MD, an internal medicine resident at the University of Washington, Seattle, who presented the findings at The Liver Meeting 2024: American Association for the Study of Liver Diseases (AASLD).
“However, people shouldn’t interpret our findings as a lack of primary care training or management,” she said. “Instead, this study indicates that AI can complement physician workflow and address the limitations of traditional clinical practice.”
Developing an MASLD Algorithm
Typically, the identification of MASLD has relied on clinician recognition and descriptions in chart notes, Stuart said. Early-stage disease often goes unnoticed, particularly if patients remain asymptomatic, until cirrhosis develops.
To address this, Stuart and colleagues created a machine learning, natural language processing AI algorithm on the basis of MASLD criteria from AASLD: Hepatic steatosis on imaging and at least one metabolic factor (elevated body mass index, hypertension, prediabetes or diabetes, or dyslipidemia). The model was validated by two physicians, who manually reviewed monthly cohorts generated by the algorithm.
Between December 2023 and May 2024, the researchers used the algorithm to analyze an MASLD cohort from medical centers in the Seattle area. The mean age was 51 years, 44% were women, and 68% were White. Those with alcohol-associated liver disease, metastatic malignancy, and autoimmune, genetic, and infectious causes of liver disease were excluded.
The algorithm identified 957 patients with imaging that matched MASLD criteria.
Among those, 137 patients (17%) identified by the algorithm had an MASLD-associated diagnostic code. For these patients, the mean time from initial imaging with steatosis to diagnosis was 33 days, according to patient records.
An additional 26 patients received an MASLD diagnosis during the study period, with a mean time to diagnosis of 56.2 days.
In terms of patient management, 245 patients (26%) had contact with a gastroenterologist or hepatologist based on documentation of a letter, phone call, or office visit. In addition, 546 patients (57%) were screened for hepatitis C.
After adjusting for an over-inclusion error rate of 12.8% and an overdiagnosis rate of 0.02%, the research team found 697 patients (83%) lacked a relevant diagnosis. After multiple iterations, the algorithm achieved an accuracy of about 88%, Stuart said.
Considering Future AI Use
Stuart and colleagues are now testing the algorithm in larger groups and across longer periods.
After that, they intend to implement a quality improvement program to increase awareness for clinicians and primary care providers, as well as train users on how to interpret and move forward with findings of hepatic steatosis in patient records.
For instance, future AI models could flag patients for additional testing, improve chart review, and aid in research efforts around cardiometabolic comorbidities associated with MASLD, she said.
Looking ahead, AI tools such as these represent what’s possible for advancements in research, patient care, and clinical workflows, said Ashley Spann, MD, assistant professor and transplant hepatologist at Vanderbilt University, Nashville, Tennessee, and director of clinical research informatics for Vanderbilt’s Gastroenterology Division.
“AI, in my view, is actually augmented intelligence,” she added. “We need to think about the people and processes involved.”
Spann, who spoke about the use of AI tools in medicine in general, stressed the need for transparency in AI use, careful validation of input-output data, frameworks for machine learning models in medicine, and standardization across institutions.
“What we ultimately need is an infrastructure that supports the simultaneous deployment and evaluation of these models,” she said. “We all need to be on the same page and make sure our models work in multiple settings and make adjustments based on algorithmovigilance afterward.”
Stuart reported no relevant disclosures. Spann serves on Epic’s hepatology steering board, which has focused on how to use AI tools in electronic medical records.

MELD 3.0 Reduces Sex-Based Liver Transplant Disparities
SAN DIEGO — , according to new research.
In particular, women are now more likely to be added to the waitlist for a liver transplant, more likely to receive a transplant, and less likely to fall off the waitlist because of death.
“MELD 3.0 improved access to transplantation for women, and now waitlist mortality and transplant rates for women more closely approximate the rates for men,” said lead author Allison Kwong, MD, assistant professor of medicine and transplant hepatologist at Stanford Medicine in California.
“Overall transplant outcomes have also improved year over year,” said Kwong, who presented the findings at The Liver Meeting 2024: American Association for the Study of Liver Diseases (AASLD).
Changes in MELD and Transplant Numbers
MELD, which estimates liver failure severity and short-term survival in patients with chronic liver disease, has been used since 2002 to determine organ allocation priority for patients in the United States awaiting liver transplantation. Originally, the score incorporated three variables: creatinine, bilirubin, and the international normalized ratio (INR). MELDNa1, or MELD 2.0, was adopted in 2016 to add sodium.
“Under this system, however, there have been sex-based disparities” with women receiving lower priority scores despite similar disease severity, said Kwong.
“This has been attributed to several factors, such as the creatinine term in the MELD score underestimating renal dysfunction in women, height and body size differences, and differences in disease etiology, and how we’ve assigned exception points historically,” she reported.
Men have had a lower pretransplant mortality rate and higher deceased donor transplant rates, she added.
MELD 3.0 was developed to address these gender differences and other determinants of waitlist outcomes. The updated equation added 1.33 points for women, as well as adding other variables, such as albumin, interactions between bilirubin and sodium, and interactions between albumin and creatinine, to increase prediction accuracy.
To observe the effects of the new system, Kwong and colleagues analyzed OPTN data for patients aged 12 years or older, focusing on the records of more than 20,300 newly registered liver transplant candidates, and about 18,700 transplant recipients, during the 12 months before and 12 months after MELD 3.0 was implemented.
After the switch, 43.7% of newly registered liver transplant candidates were women, compared with 40.4% before the switch. At registration, the median age was 55, both before and after the change in policy, and the median MELD score changed from 23 to 22 after implementation.
In addition, 42.1% of transplants occurred among women after MELD 3.0 implementation, as compared with 37.3% before. Overall, deceased donor transplant rates were similar for men and women after MELD 3.0 implementation.
The 90-day waitlist dropout rate — patients who died or became too sick to receive a transplant — decreased from 13.5% to 9.1% among women, which may be partially attributable to MELD 3.0, said Kwong.
However, waitlist dropout rates also decreased among men, from 9.8% to 7.4%, probably because of improvements in technology, such as machine perfusion, which have increased the number of available livers, she added.
Disparities Continue to Exist
Some disparities still exist. Although the total median MELD score at transplant decreased from 29 to 27, women still had a higher median score of 29 at transplant, compared with a median score of 27 among men.
“This indicates that there may still be differences in transplant access between the sexes,” Kwong said. “There are still body size differences that can affect the probability of transplant, and this would not be addressed by MELD 3.0.”
Additional transplant disparities exist related to other patient characteristics, such as age, race, and ethnicity.
Future versions of MELD could potentially consider these factors, said session moderator Aleksander Krag, MD, PhD, MBA, professor of clinical medicine at the University of Southern Denmark, Odense, and secretary general of the European Association for the Study of the Liver, 2023-2025.
“There are infinite versions of MELD that can be made,” Kwong said. “It’s still early to see how MELD 3.0 will serve the system, but so far, so good.”
In a comment, Tamar Taddei, MD, professor of medicine in digestive diseases at Yale School of Medicine, New Haven, Connecticut, who comoderated the session, noted the importance of using a MELD score that considers sex-based differences.
This study brings MELD 3.0 to its fruition by reducing the disparities experienced by women who were underserved by the previous scoring systems, she said.
It was lovely to see that MELD 3.0 reduced the disparities with transplants, and also that the waitlist dropout was reduced — for both men and women,” Taddei said. “This change is a no-brainer.”
Kwong, Krag, and Taddei reported no relevant disclosures.

‘Watershed Moment’: Semaglutide Shown to Be Effective in MASH
SAN DIEGO — according to interim results from a phase 3 trial.
At 72 weeks, a 2.4-mg once-weekly subcutaneous dose of semaglutide demonstrated superiority, compared with placebo, for the two primary endpoints: Resolution of steatohepatitis with no worsening of fibrosis and improvement in liver fibrosis with no worsening of steatohepatitis.
“It’s been a long journey. I’ve been working with GLP-1s for 16 years, and it’s great to be able to report the first GLP-1 receptor agonist to demonstrate efficacy in a phase 3 trial for MASH,” said lead author Philip Newsome, MD, PhD, director of the Roger Williams Institute of Liver Studies at King’s College London in England.
“There were also improvements in a slew of other noninvasive markers,” said Newsome, who presented the findings at The Liver Meeting 2024: American Association for the Study of Liver Diseases (AASLD).
Although already seen in a broader context, “it’s nice to see a demonstration of the cardiometabolic benefits in the context of MASH and a reassuring safety profile,” he added.
Interim ESSENCE Trial Analysis
ESSENCE (NCT04822181) is an ongoing multicenter, phase 3 randomized, double-blind, placebo-controlled outcome trial studying semaglutide for the potential treatment of MASH.
The trial includes 1200 participants with biopsy-defined MASH and fibrosis, stages F2 and F3, who were randomized 2:1 to a once-weekly subcutaneous injection of 2.4 mg of semaglutide or placebo for 240 weeks. After initiation, the semaglutide dosage was increased every 4 weeks up to 16 weeks when the full dose (2.4 mg) was reached.
In a planned interim analysis, the trial investigators evaluated the primary endpoints at week 72 for the first 800 participants, with biopsies taken at weeks 1 and 72.
A total of 534 people were randomized to the semaglutide group, including 169 with F2 fibrosis and 365 with F3 fibrosis. Among the 266 participants randomized to placebo, 81 had F2 fibrosis and 185 had F3 fibrosis.
At baseline, the patient characteristics were similar between the groups (mean age, 56 years; body mass index, 34.6). A majority of participants also were White (67.5%), women (57.1%), had type 2 diabetes (55.9%), F3 fibrosis (68.8%), and enhanced liver fibrosis (ELF) scores around 10 (55.5%).
For the first primary endpoint, 62.9% of those in the semaglutide group and 34.1% of those in the placebo group reached resolution of steatohepatitis with no worsening of fibrosis. This represented an estimated difference in responder proportions (EDP) of 28.9%.
In addition, 37% of those in the semaglutide group and 22.5% of those in the placebo group met the second primary endpoint of improvement in liver fibrosis with no worsening of steatohepatitis (EDP, 14.4%).
Among the secondary endpoints, combined resolution of steatohepatitis with a one-stage improvement in liver fibrosis occurred in 32.8% of the semaglutide group and 16.2% of the placebo group (EDP, 16.6%).
In additional analyses, Newsome and colleagues found 20%-40% improvements in liver enzymes and noninvasive fibrosis markers, such as ELF and vibration-controlled transient elastography liver stiffness.
Weight loss was also significant, with a 10.5% reduction in the semaglutide group compared with a 2% reduction in the placebo group.
Cardiometabolic risk factors improved as well, with changes in blood pressure measurements, hemoglobin A1c scores, and cholesterol values.
Although not considered statistically significant, patients in the semaglutide group also reported greater reductions in body pain.
In a safety analysis of 1195 participants at 96 weeks, adverse events, severe adverse events, and discontinuations were similar in both groups. Not surprisingly, gastrointestinal side effects were more commonly reported in the semaglutide group, Newsome said.
Highly Anticipated Results
After Newsome’s presentation, attendees applauded.
Rohit Loomba, MD, a gastroenterologist at the University of California, San Diego, who was not involved with the study, called the results the “highlight of the meeting.”
This sentiment was echoed by Naga Chalasani, MD, AGAF, a gastroenterologist at Indiana University Medical Center, Indianapolis, who called the results a “watershed moment in the MASH field” with “terrific data.”
Based on questions after the presentation, Newsome indicated that future ESSENCE reports would look at certain aspects of the results, such as the 10% weight loss among those in the semaglutide group, as well as the mechanisms of histological and fibrosis improvement.
“We know from other GLP-1 trials that more weight loss occurs in those who don’t have type 2 diabetes, and we’re still running those analyses,” he said. “Weight loss is clearly a major contributor to MASH improvement, but there seem to be some weight-independent effects here, which are likely linked to insulin sensitivity or inflammation. We look forward to presenting those analyses in due course.”
In a comment, Kimberly Ann Brown, MD, AGAF, chief of gastroenterology and hepatology at Henry Ford Health System in Detroit, Michigan, AASLD Foundation chair, and comoderator of the late-breaking abstract session, spoke about the highly anticipated presentation.
“This study was really the pinnacle of this meeting. We’ve all been waiting for this data, in large part because many of our patients are already using these medications,” Brown said. “Seeing the benefit for the liver, as well as lipids and other cardiovascular measures, is so important. Having this confirmatory study will hopefully lead to the availability of the medication for this indication among our patients.”
Newsome reported numerous disclosures, including consultant relationships with pharmaceutical companies, such as Novo Nordisk, Boehringer Ingelheim, and Madrigal Pharmaceuticals. Loomba has research grant relationships with numerous companies, including Hanmi, Gilead, Galmed Pharmaceuticals, Galectin Therapeutics, Eli Lilly, Bristol-Myers Squibb, and Boehringer Ingelheim. Chalasani has consultant relationships with Ipsen, Pfizer, Merck, Altimmune, GSK, Madrigal Pharmaceuticals, and Zydus. Brown reported no relevant disclosures.

ESSENCE (NCT04822181) is an ongoing multicenter, phase 3 randomized, double-blind, placebo-controlled outcome trial studying semaglutide for the potential treatment of MASH.
The trial includes 1200 participants with biopsy-defined MASH and fibrosis, stages F2 and F3, who were randomized 2:1 to a once-weekly subcutaneous injection of 2.4 mg of semaglutide or placebo for 240 weeks. After initiation, the semaglutide dosage was increased every 4 weeks up to 16 weeks when the full dose (2.4 mg) was reached.
In a planned interim analysis, the trial investigators evaluated the primary endpoints at week 72 for the first 800 participants, with biopsies taken at weeks 1 and 72.
A total of 534 people were randomized to the semaglutide group, including 169 with F2 fibrosis and 365 with F3 fibrosis. Among the 266 participants randomized to placebo, 81 had F2 fibrosis and 185 had F3 fibrosis.
At baseline, the patient characteristics were similar between the groups (mean age, 56 years; body mass index, 34.6). A majority of participants also were White (67.5%), women (57.1%), had type 2 diabetes (55.9%), F3 fibrosis (68.8%), and enhanced liver fibrosis (ELF) scores around 10 (55.5%).
For the first primary endpoint, 62.9% of those in the semaglutide group and 34.1% of those in the placebo group reached resolution of steatohepatitis with no worsening of fibrosis. This represented an estimated difference in responder proportions (EDP) of 28.9%.
In addition, 37% of those in the semaglutide group and 22.5% of those in the placebo group met the second primary endpoint of improvement in liver fibrosis with no worsening of steatohepatitis (EDP, 14.4%).
Among the secondary endpoints, combined resolution of steatohepatitis with a one-stage improvement in liver fibrosis occurred in 32.8% of the semaglutide group and 16.2% of the placebo group (EDP, 16.6%).
In additional analyses, Newsome and colleagues found 20%-40% improvements in liver enzymes and noninvasive fibrosis markers, such as ELF and vibration-controlled transient elastography liver stiffness.
Weight loss was also significant, with a 10.5% reduction in the semaglutide group compared with a 2% reduction in the placebo group.
Cardiometabolic risk factors improved as well, with changes in blood pressure measurements, hemoglobin A1c scores, and cholesterol values.
Although not considered statistically significant, patients in the semaglutide group also reported greater reductions in body pain.
In a safety analysis of 1195 participants at 96 weeks, adverse events, severe adverse events, and discontinuations were similar in both groups. Not surprisingly, gastrointestinal side effects were more commonly reported in the semaglutide group, Newsome said.
Highly Anticipated Results
After Newsome’s presentation, attendees applauded.
Rohit Loomba, MD, a gastroenterologist at the University of California, San Diego, who was not involved with the study, called the results the “highlight of the meeting.”
This sentiment was echoed by Naga Chalasani, MD, AGAF, a gastroenterologist at Indiana University Medical Center, Indianapolis, who called the results a “watershed moment in the MASH field” with “terrific data.”
Based on questions after the presentation, Newsome indicated that future ESSENCE reports would look at certain aspects of the results, such as the 10% weight loss among those in the semaglutide group, as well as the mechanisms of histological and fibrosis improvement.
“We know from other GLP-1 trials that more weight loss occurs in those who don’t have type 2 diabetes, and we’re still running those analyses,” he said. “Weight loss is clearly a major contributor to MASH improvement, but there seem to be some weight-independent effects here, which are likely linked to insulin sensitivity or inflammation. We look forward to presenting those analyses in due course.”
In a comment, Kimberly Ann Brown, MD, AGAF, chief of gastroenterology and hepatology at Henry Ford Health System in Detroit, Michigan, AASLD Foundation chair, and comoderator of the late-breaking abstract session, spoke about the highly anticipated presentation.
“This study was really the pinnacle of this meeting. We’ve all been waiting for this data, in large part because many of our patients are already using these medications,” Brown said. “Seeing the benefit for the liver, as well as lipids and other cardiovascular measures, is so important. Having this confirmatory study will hopefully lead to the availability of the medication for this indication among our patients.”
Newsome reported numerous disclosures, including consultant relationships with pharmaceutical companies, such as Novo Nordisk, Boehringer Ingelheim, and Madrigal Pharmaceuticals. Loomba has research grant relationships with numerous companies, including Hanmi, Gilead, Galmed Pharmaceuticals, Galectin Therapeutics, Eli Lilly, Bristol-Myers Squibb, and Boehringer Ingelheim. Chalasani has consultant relationships with Ipsen, Pfizer, Merck, Altimmune, GSK, Madrigal Pharmaceuticals, and Zydus. Brown reported no relevant disclosures.

SAN DIEGO — according to interim results from a phase 3 trial.
At 72 weeks, a 2.4-mg once-weekly subcutaneous dose of semaglutide demonstrated superiority, compared with placebo, for the two primary endpoints: Resolution of steatohepatitis with no worsening of fibrosis and improvement in liver fibrosis with no worsening of steatohepatitis.
“It’s been a long journey. I’ve been working with GLP-1s for 16 years, and it’s great to be able to report the first GLP-1 receptor agonist to demonstrate efficacy in a phase 3 trial for MASH,” said lead author Philip Newsome, MD, PhD, director of the Roger Williams Institute of Liver Studies at King’s College London in England.
“There were also improvements in a slew of other noninvasive markers,” said Newsome, who presented the findings at The Liver Meeting 2024: American Association for the Study of Liver Diseases (AASLD).
Although already seen in a broader context, “it’s nice to see a demonstration of the cardiometabolic benefits in the context of MASH and a reassuring safety profile,” he added.

Canadian Scientists Keep Watchful Eye on H5N1 Human Case
Now that Canada has confirmed its first human case of highly pathogenic avian influenza (HPAI) linked to H5N1, virologists and infectious disease experts are urging caution around surveillance, infection control, and the potential for spread among mammals and humans.
Public health officials at the National Microbiology Laboratory in Winnipeg, Manitoba, Canada, confirmed that the virus strain is related to the ones circulating among poultry in British Columbia.
So far, the case appears to be isolated, and no additional infections have been detected among the teen’s family, friends, or healthcare workers. But Canadian and American scientists who have studied the genetic sequence of the virus have found mutations that could make it easier to infect humans. Even if this strain remains contained after the teen’s case resolves, the mere fact that mutations have occurred could be a cause for concern about future strains.
“HPAI is one of those diseases that scientists, public health specialists, animal health specialists, and physicians have been watching closely for 20 years due to its epidemic and pandemic potential, including impacts to agriculture, food security, and financial security,” Isaac Bogoch, MD, associate professor of medicine at the University of Toronto and infectious disease specialist with the University Health Network, Toronto, Ontario, Canada, said in an interview.
“The last couple of years have been notable in that the H5N1 outbreak among wild birds and migratory birds has been larger, and the spillover to dairy cows and humans in the US is obviously concerning,” he said. “As we see more viral reassortment and more mammals are impacted, the more opportunities there are for this to go awry.”
Current H5N1 Outlook
Canadian public health officials and virologists are still unsure how the teen in British Columbia became infected, Bogoch said. The case has prompted concern due to the disease severity and need for hospitalization, while other cases across North America have remained mild.
The United States has reported 53 human cases as of November 21, according to the Centers for Disease Control and Prevention. In all but one case, the infections occurred among dairy or poultry workers, primarily in California, Colorado, and Washington. In all these cases, patients have reported mild symptoms, including mild respiratory issues and conjunctivitis. None have been hospitalized.
In Canada, the teen was infected with a strain of the virus circulating in wild birds. This strain has also been found in poultry outbreaks in British Columbia and Washington during the past month. So far, the risk for infection remains low for the public, according to the Public Health Agency of Canada.
“This detection was picked up via hospital-based influenza surveillance, confirming that human influenza surveillance in British Columbia and Canada is effective at detecting avian influenza A (H5N1),” Theresa Tam, MD, Canada’s chief public health officer, said in a statement. “We must continue to remain vigilant in our efforts to prevent the spread of avian influenza between animals and to humans.”
For now, Canadian virologists are watching developments closely and urging caution among those who encounter wild or migratory birds but not recommending major changes overall.
“The fact that we have a first human case in Canada is not at all surprising, given what is happening in the US and Europe, as well as what is happening in domestic bird flocks in British Columbia,” said Brian Ward, MD, professor of medicine at McGill University, researcher with McGill’s JD MacLean Centre for Tropical Diseases, and co-director of McGill’s Vaccine Study Centre, Montreal, Quebec, Canada.
“Millions of migratory waterfowl are flying over Canada right now, many of which may be carrying or infected with the virus,” he said. “The bottom line is that increasing evidence of mammal-to-mammal spread among dairy cows, elephant seals, and mink and ermine farms is worrisome, but we don’t need to sound the sirens yet.”
Future Outbreak Measures
Looking ahead, though, the developing situation feels more threatening than benign, given the ongoing spread among dairy cattle in the United States, said Bogoch. “It’s difficult to get the genie back in the bottle. I had hoped to see the cases slow down this year, but we just haven’t seen that.”
The fact that surveillance measures such as wastewater sampling have been scaled back in some areas of Canada is cause for concern, Bogoch added.
“We have great foundations for surveillance and action; we just need to make sure they are supported adequately, that groups communicate (across too many silos), and that there are quick responses,” said Scott Weese, DVM, professor of pathobiology at the Ontario Veterinary College and director of the University of Guelph’s Centre for Public Health and Zoonoses in Ontario.
“With cattle in the US, I think it’s highlighted what can happen if the initial response is not very aggressive. There could have been a lot more proactive response to H5N1 in dairy cattle, but there are so many competing interests and unwillingness to take necessary steps that the virus continues to spread,” he said. “Hopefully we’ve learned from that. However, as is often the case, the science is sometimes the easy part. Getting people to take the required actions is the challenge.”
On a personal level, masks and social distancing work well against influenza virus, including both seasonal and avian strains, said Ward. On a broader level, healthcare providers can monitor patients and support testing, where appropriate.
“The most important thing for people to know is that there is going to be another pandemic. It might or might not be due to a variant of H5N1, but it will come at some time,” said Allison McGeer, MD, professor of laboratory medicine and pathobiology at the University of Toronto and an infectious disease specialist with the Sinai Health System, Toronto.
Healthcare providers should follow ongoing updates to public health guidance, support surveillance where possible, and work with hospital leadership and infection control officials to ensure that pandemic plans are in place, she said.
“They may not be needed in the next few months, but they will be needed,” McGeer said. “We know a lot more about influenza than we did about SARS-CoV-2, so we have more tools to mitigate the impact, but we need to have them ready and know how to use them effectively.”

Alcohol-Associated Liver Disease and Alcohol Use Disorder on the Rise in Older Adults
SAN DIEGO — according to the results of a new study.
Even as mortality rates decline globally, AUD deaths rose in the United States, increasing 1.63% per year between 2010 and 2019. Deaths from cirrhosis increased by 0.56% each year, and deaths from primary liver cancer associated with alcohol increased by 3.09% per year.
Several factors, such as an aging US population and increasing alcohol consumption, play a major role in the uptick in mortality, said lead author Pojsakorn Danpanichkul, MD, an internal medicine resident at Texas Tech University Health Sciences Center, Lubbock, who presented the findings at The Liver Meeting 2024: American Association for the Study of Liver Diseases (AASLD).
“Healthcare providers should increase screening for alcohol use among older adults and consider the added risks of alcohol consumption. Public health strategies should target alcohol prevention and treatment programs tailored to older adults,” he said.
“Older adults are more vulnerable to the harmful effects of alcohol due to natural declines in liver function and metabolism, leading to a higher risk of liver disease and complications,” he explained. However, “little research has focused on this issue.”
Trends in US Not Seen Globally
Danpanichkul and colleagues analyzed data from the Global Burden of Disease Study for 2010-2019, calculating the annual percent change for the burden of AUD, ALD, and liver cancer from alcohol in patients age 70 and older. The research team then compared data in the United States to global estimates for these same diseases.
In 2019, there were 556,340 cases of AUD, 112,560 cases of ALD, and 3720 cases of liver cancer from alcohol in older adults in the United States. In addition, there were 1750 deaths attributed to AUD, 4860 deaths from ALD, and 3010 deaths caused by primary liver cancer from alcohol.
The age-standardized prevalence rates (ASPRs) per 100,000 people were 1547 cases of AUD, 313 cases of ALD, and 10 cases of primary liver cancer caused by alcohol.
The age-standardized death rates (ASDRs) per 100,000 people were 4.88 for AUD, 13.52 for ALD, and 8.38 for primary liver cancer.
During the time period studied, upward trends occurred in the United States, with annual ASPRs increasing by 2.52% for AUD, 1.78% for ALD, and 3.31% for primary liver cancer due to alcohol. Globally, the trends were lower, with annual increases of 0.2% for AUD, 0.38% for ALD, and 0.67% for primary liver cancer from alcohol.
During the same time, ASDRs also increased in all three categories in the United States, while global trends showed a 0.91% decline in AUD deaths and 0.6% decline in ALD deaths. Liver cancer deaths, however, increased by 0.3% worldwide.
Targeted strategies are essential to reduce this growing health burden, especially in an aging population, Danpanichkul said. “These interventions should focus on early detection, intervention, and management for individuals at risk or already affected by ALD and AUD.”
Future studies should investigate alcohol consumption and mortality trends in other age groups, including by sex, location (such as state or territory), and race and ethnicity, he said. Data for more recent years would be compelling as well.
Increased Alcohol Use During and After Pandemic
Numerous studies have indicated that alcohol use increased in 2020 during the COVID-19 pandemic and has remained elevated since then.
In a study published in the Annals of Internal Medicine, for instance, alcohol use per 100 people increased 2.69% in 2020 and 2.96% in 2022, as compared with 2018. Increases occurred across all subgroups, including age, sex, race, ethnicity, and US region.
“During the COVID-19 pandemic, many people stayed at home, watched the television, and increased their alcohol intake” — in the United States and also in Japan — said Hisanori Muto, MD, senior assistant professor of gastroenterology at Fujita Health University in Nagoya, Japan, who wasn’t involved with this study.
“Although the global numbers may appear lower, we’re also seeing an increase in AUD and ALD in Japan, similar to the United States,” he said. “It’s very important to watch these trends and address these diseases.”
Danpanichkul and Muto reported no relevant disclosures.

Trends in US Not Seen Globally
Danpanichkul and colleagues analyzed data from the Global Burden of Disease Study for 2010-2019, calculating the annual percent change for the burden of AUD, ALD, and liver cancer from alcohol in patients age 70 and older. The research team then compared data in the United States to global estimates for these same diseases.
In 2019, there were 556,340 cases of AUD, 112,560 cases of ALD, and 3720 cases of liver cancer from alcohol in older adults in the United States. In addition, there were 1750 deaths attributed to AUD, 4860 deaths from ALD, and 3010 deaths caused by primary liver cancer from alcohol.
The age-standardized prevalence rates (ASPRs) per 100,000 people were 1547 cases of AUD, 313 cases of ALD, and 10 cases of primary liver cancer caused by alcohol.
The age-standardized death rates (ASDRs) per 100,000 people were 4.88 for AUD, 13.52 for ALD, and 8.38 for primary liver cancer.
During the time period studied, upward trends occurred in the United States, with annual ASPRs increasing by 2.52% for AUD, 1.78% for ALD, and 3.31% for primary liver cancer due to alcohol. Globally, the trends were lower, with annual increases of 0.2% for AUD, 0.38% for ALD, and 0.67% for primary liver cancer from alcohol.
During the same time, ASDRs also increased in all three categories in the United States, while global trends showed a 0.91% decline in AUD deaths and 0.6% decline in ALD deaths. Liver cancer deaths, however, increased by 0.3% worldwide.
Targeted strategies are essential to reduce this growing health burden, especially in an aging population, Danpanichkul said. “These interventions should focus on early detection, intervention, and management for individuals at risk or already affected by ALD and AUD.”
Future studies should investigate alcohol consumption and mortality trends in other age groups, including by sex, location (such as state or territory), and race and ethnicity, he said. Data for more recent years would be compelling as well.
Increased Alcohol Use During and After Pandemic
Numerous studies have indicated that alcohol use increased in 2020 during the COVID-19 pandemic and has remained elevated since then.
In a study published in the Annals of Internal Medicine, for instance, alcohol use per 100 people increased 2.69% in 2020 and 2.96% in 2022, as compared with 2018. Increases occurred across all subgroups, including age, sex, race, ethnicity, and US region.
“During the COVID-19 pandemic, many people stayed at home, watched the television, and increased their alcohol intake” — in the United States and also in Japan — said Hisanori Muto, MD, senior assistant professor of gastroenterology at Fujita Health University in Nagoya, Japan, who wasn’t involved with this study.
“Although the global numbers may appear lower, we’re also seeing an increase in AUD and ALD in Japan, similar to the United States,” he said. “It’s very important to watch these trends and address these diseases.”
Danpanichkul and Muto reported no relevant disclosures.

SAN DIEGO — according to the results of a new study.
Even as mortality rates decline globally, AUD deaths rose in the United States, increasing 1.63% per year between 2010 and 2019. Deaths from cirrhosis increased by 0.56% each year, and deaths from primary liver cancer associated with alcohol increased by 3.09% per year.
Several factors, such as an aging US population and increasing alcohol consumption, play a major role in the uptick in mortality, said lead author Pojsakorn Danpanichkul, MD, an internal medicine resident at Texas Tech University Health Sciences Center, Lubbock, who presented the findings at The Liver Meeting 2024: American Association for the Study of Liver Diseases (AASLD).
“Healthcare providers should increase screening for alcohol use among older adults and consider the added risks of alcohol consumption. Public health strategies should target alcohol prevention and treatment programs tailored to older adults,” he said.

In IBD Patients, No Increased Risk for MACE Seen for JAK Inhibitors vs Anti-TNF
PHILADELPHIA — according to a study presented at the American College of Gastroenterology (ACG) 2024 Annual Scientific Meeting.
In particular, 1.76% of patients taking JAKi and 1.94% of patients taking anti-TNF developed MACE. There also weren’t significant differences when comparing ulcerative colitis with Crohn’s disease, upadacitinib with tofacitinib, or JAKi with infliximab.
“IBD is associated with an increased risk of cardiovascular diseases, and with the emergence of JAK inhibitors and anti-TNF therapies, there is a concern about the increased risk of MACE,” said lead author Saqr Alsakarneh, MD, an internal medicine resident at the University of Missouri–Kansas City School of Medicine.
Previous randomized controlled trials have indicated increased risks of MACE with JAKi and anti-TNF agents, compared with placebo, but researchers haven’t conducted a head-to-head comparison, he said.
“A potential explanation for previous associations could be linked to immune modulation and inflammation that can increase coagulation risk, as well as fluctuation in disease severity while patients are on the medications, which can impact cardiovascular risk factors,” he added.
Alsakarneh and colleagues conducted a retrospective cohort study using the TriNetX database to identify adult patients with IBD who were treated with JAKi or anti-TNF therapy after diagnosis. After matching patients in the JAKi cohort with patients in the anti-TNF cohort, the research team looked for MACE and VTE within a year of medication initiation, as well as associations by age, sex, and IBD type.
Overall, 3740 patients in the JAKi cohort had a mean age of 43.1 and were 48.9% women and 75.3% White individuals, while 3,740 patients in the anti-TNF cohort had a mean age of 43 and were 48.9% women and 75.3% White individuals.
After excluding those with a history of a prior cardiovascular event, 57 patients (1.76%) in the JAKi cohort developed MACE, compared with 63 patients (1.94%) in the anti-TNF cohort. There weren’t significant differences between the groups in MACE (adjusted hazard ratio [aHR], 0.99) or VTE (aHR, 0.9).
Among patients aged ≥ 65, 25 patients (5.3%) in the JAKi cohort developed MACE, as compared with 30 patients (6.4%) in the anti-TNF cohort. There weren’t significant differences between the groups in MACE (aHR, 0.83) or VTE (aHR, 0.77).
In addition, there were no differences when comparing Crohn’s disease with ulcerative colitis for MACE (aHR, 1.69) or VTE (aHR, 0.85); upadacitinib with tofacitinib for MACE (aHR, 1.1) or VTE (aHR, 1.13); or JAKi medications with infliximab for MACE (aHR, 0.85) or VTE (aHR, 0.8).
Patients in the JAKi group were more likely to undergo intestinal resection surgery (aHR, 1.32), but there wasn’t a statistically significant difference in systematic corticosteroid use (aHR, 0.99).
The study limitations included the inability to assess for disease severity, dose-dependent risk for MACE or VTE, or long-term outcomes among the two cohorts, Alsakarneh said. Prospective controlled trials are needed to confirm findings.
“This is a wonderful study and nice to see. We presented the same thing at Digestive Disease Week that’s being confirmed in this data,” said Miguel Regueiro, MD, AGAF, chief of Cleveland Clinic’s Digestive Disease Institute in Ohio. Regueiro, who wasn’t involved with the study, attended the conference session.
“Looking ahead, all of us are wondering if the regulatory guidance by the FDA [Food and Drug Administration] is going to change the label so we don’t need to step through a TNF,” he said. “I think we’re seeing study after study showing safety or at least not an increased risk with JAK.”
The study was awarded an ACG Noteworthy Abstract. Alsakarneh and Regueiro reported no relevant disclosures.

Alcohol Use Disorder Therapy Remains Underutilized in Alcohol-Associated Liver Disease
PHILADELPHIA — according to a study presented at the American College of Gastroenterology (ACG) 2024 Annual Scientific Meeting.
In an analysis of commercially insured Americans, AUD medications were prescribed to only 1 in 50 patients with ALD and about 1 in 10 patients with acute alcohol-associated hepatitis (AAH).
“Providers caring for these patients should consider early initiation of this therapy in select cases,” said lead author Alex R. Jones, MD, chief resident of internal medicine at the University of Texas Southwestern Medical Center in Dallas.
“Based on additional analyses looking at the prescriber subspecialty, we didn’t identify any gastroenterologists or hepatologists who prescribed pharmacotherapy,” he said. “This could be a great opportunity for hepatologists to engage in the pharmacologic treatment of AUD.”
Jones and colleagues analyzed 2006-2021 data from IQVIA PharMetrics Plus for Academics, a nationally representative database of commercially insured patients in the United States. They looked for AUD pharmacologic treatment at any time after AUD diagnosis, including prescriptions for gabapentin, naltrexone, topiramate, acamprosate, baclofen, and disulfiram.
Among 28,625 patients with AUD (defined as at least two outpatient codes or at least one inpatient code), 1201 had ALD with cirrhosis and 439 had AAH.
Pharmacologic therapy was prescribed in 3924 (14.5%) patients without ALD, 28 (2.3%) with ALD, and 42 (9.8%) with AAH.
In addition, one-time prescriptions were observed in 1113 (28.4%) patients without ALD, three patients (10.7%) with ALD, and eight patients (18.6%) with AAH.
Overall, 64.5% of the general population consisted of men. About 46% had a psychiatric diagnosis other than substance use disorder (SUD), and 35.7% had a non-AUD SUD.
Patients who received AUD pharmacotherapy tended to be older, at a median age of 45 years, than those aged 42 years without a prescription.
The median time to prescription was 302 days, with no significant differences based on the presence of liver disease.
By medication, gabapentin was prescribed most often (9.4%), followed by oral naltrexone (2.6%) and topiramate (2%). Oral naltrexone was prescribed at a lower rate in patients with ALD and at a higher rate in patients with AAH than in patients without ALD. Baclofen was also prescribed at lower rates in patients with ALD and AAH.
In a multivariable logistic regression analysis, several characteristics were more significantly associated with pharmacologic therapy, such as age ≥ 50 years (adjusted odds ratio [aOR], 1.33), female sex (aOR, 1.31), a non-liver Charlson Comorbidity Index ≥ 3 (aOR, 2.21), and psychiatric comorbidities (aOR, 2.76).
On the other hand, the presence of hepatic decompensation — defined as ascites, hepatic encephalopathy, or bleeding varices — was associated with lower odds of receiving pharmacotherapy (aOR, 0.08). ALD cirrhosis (non-AAH) also had lower odds (aOR, 0.24).
The study was limited by only incorporating patients with commercial insurance, lacking demographic details related to race or ethnicity, and potentially misclassifying patients despite validated definitions of ALD and AUD, Jones said.
As the study couldn’t determine the indications for prescriptions, such as gabapentin use for migraines or diabetes-associated neuropathy, for instance, future studies could look at these precise details, he added.
“It’s important to know we’re underutilizing therapies that we have a lot of information about, such as gabapentin, which is an old medication that we should feel fairly comfortable using,” said Patricia Jones, MD, a hepatologist and associate professor of clinical medicine at the University of Miami Miller School of Medicine, in Florida. Patricia Jones comoderated the plenary session on small intestine, functional, and liver research.
“I also expect that, if a future study reviewed this data and excluded people with valid indications, such as migraines or diabetic neuropathy, we’d see even lower rates of prescription,” she said.
From a clinical perspective, patient communication and clinical decision-making are key, Patricia Jones added, particularly when clinical gastroenterologists and hepatologists may not offer this type of therapy or patients refuse this type of therapy.
“We need to think about our practice patterns and how we can offer therapy,” she said. “In general, we know these medications are very safe. Even though they’re not widely used in people with cirrhosis, there’s not enough evidence to suggest we shouldn’t use them.”

Patricia Jones comoderated the plenary session on small intestine, functional, and liver research.
“I also expect that, if a future study reviewed this data and excluded people with valid indications, such as migraines or diabetic neuropathy, we’d see even lower rates of prescription,” she said.
From a clinical perspective, patient communication and clinical decision-making are key, Patricia Jones added, particularly when clinical gastroenterologists and hepatologists may not offer this type of therapy or patients refuse this type of therapy.
“We need to think about our practice patterns and how we can offer therapy,” she said. “In general, we know these medications are very safe. Even though they’re not widely used in people with cirrhosis, there’s not enough evidence to suggest we shouldn’t use them.”

PRECISE-DAPT Score Predicts GI Bleeding Risk Among Post-PCI Patients
PHILADELPHIA — Gastrointestinal (GI) bleeding after percutaneous coronary intervention (PCI) among patients on dual antiplatelet therapy (DAPT) remains risky in terms of morbidity and mortality, but the Predicting Bleeding Complications in Patients Undergoing Stent Implantation and Subsequent Dual Antiplatelet Therapy (PRECISE-DAPT) score could help predict that risk, according to a study presented at the American College of Gastroenterology (ACG) 2024 Annual Scientific Meeting.
In a predominantly Hispanic population in Texas, 2.5% of post-PCI patients on DAPT had GI bleeding in the first year.
“Our study established that the PRECISE-DAPT score possesses a moderate predictive accuracy not only for overall bleeding risk but also specifically for gastrointestinal bleeding,” said lead author Jesus Guzman, MD, a gastroenterology fellow at the Texas Tech University Health Sciences Center El Paso.
Current guidelines from the American College of Cardiology and American Heart Association recommend DAPT for 6-12 months post-PCI, with consideration for shorter durations in patients with lower ischemic risks but higher bleeding risks.
“Interestingly, some of these patients were on DAPT for more than 2 years, which goes beyond the guidelines,” he said. “In this patient population, this has to do with them being lost to follow-up and getting reestablished, and they kept refilling their prescriptions.”
Guzman and colleagues conducted a retrospective cohort study of patients receiving DAPT after PCI from 2014 to 2021. They looked for GI bleeding rates at 1 year and across the duration of the study period, as well as endoscopic indications, findings, concurrent antiplatelet therapy, and the primary cause of bleeding.
In addition, the research team evaluated the predictive value of the PRECISE-DAPT score, which categorizes patients based on low risk (≤ 17), moderate risk (18-24), and high risk (≥ 25) for bleeding. The score aims to optimize the balance between bleeding and ischemic risks, Guzman said, by incorporating five factors: Age, creatinine clearance, hemoglobin, white blood cell count, and history of spontaneous bleeding.
Among 1067 patients, 563 (57.9%) received clopidogrel and 409 (42%) received ticagrelor. The overall cohort was 66.6% men, 77.1% Hispanic, and had a mean age of 62 years.
The GI bleeding rate was 2.5% at 1-year post-PCI among 27 patients and 3.7% for the study duration among 39 patients, with a median follow-up of 2.2 years.
Among the 39 GI bleeds, 41% were lower GI bleeds, 28% were upper GI bleeds, 15% were small bowel bleeds, and 15% were undetermined. The most frequent etiology was colon cancer, accounting for 18% of bleeds, followed by 15% for gastric ulcers, 10% for diverticular bleeds, and 10% for hemorrhoidal bleeds.
In general, analyses indicated no significant differences in GI bleeding between patients on clopidogrel (21.2%) and those on ticagrelor (19.2%).
However, the odds of GI bleeding were significantly higher in patients with high-risk PRECISE-DAPT scores (odds ratio [OR], 2.5) and moderate-risk scores (OR, 2.8) than in those with low-risk scores. The majority of patients without GI bleeding had scores < 17, whereas the majority of patients with GI bleeding had scores > 24. An optimal threshold for the PRECISE-DAPT score was identified as ≥ 19.
“When patients on DAPT present with GI bleeding, it can be a clinical conundrum for gastroenterologists and cardiologists, especially when it can be a life-or-death event, and stopping DAPT can increase risk of thrombosis,” said Jeff Taclob, MD, a hepatology fellow at The University of Tennessee Health Science Center in Memphis. Taclob, who wasn’t involved with the study, attended the conference session.
“In this population in El Paso, in particular, many patients don’t have adequate healthcare, may be lost to follow-up, and get their prescriptions filled elsewhere, such as Juárez, Mexico,” he said. “Then they come in with this life-threatening bleed, so we need to focus more on their risks.”
Paying attention to specific patient populations, cultures, and values remains important for patient communication and clinical decision-making, Taclob noted.
“In this population of older men, there’s often a macho persona where they don’t want to seek help,” he said. “DAPT criteria could differ in other populations, but here, the PRECISE-DAPT score appeared to help.”
The study was awarded the ACG Outstanding Research Award in the GI Bleeding Category (Trainee). Guzman and Taclob reported no relevant disclosures.

Angiotensin Receptor Blockers May Lead to Worse Outcomes in Celiac Disease
PHILADELPHIA — , according to a study presented at the American College of Gastroenterology (ACG) 2024 Annual Scientific Meeting.
The association may be related to the similar pathophysiology between ARB-associated enteropathy and celiac disease, though additional research is needed.
“Based on our findings, people should take caution when prescribing angiotensin receptor blockers to people with celiac disease,” said lead author Isabel Hujoel, MD, clinical assistant professor of gastroenterology and clinic director of the Celiac Disease Center at the University of Washington, Seattle.
“When we see someone with nonresponsive celiac disease, meaning persistent symptoms despite a gluten-free diet, I do think we should review their medication list, and if they’re on an ARB, we should consider a trial off those medications to see if they respond,” she said. “A primary care provider may choose other hypertensives as well.”
Hujoel and co-author Margaux Hujoel, PhD, a postdoctoral research fellow at Brigham and Women’s Hospital, Boston; Broad Institute, Cambridge; and Harvard Medical School, Boston, analyzed data from the National Institutes of Health’s All of Us, a large publicly available US longitudinal dataset.
The researchers conducted a survival analysis of time-to-first event after celiac disease diagnosis, allowing patients to have a time-dependent covariate of ARB use. They looked at outcomes such as iron deficiency, diarrhea, abdominal pain, vitamin deficiency, vitamin D deficiency, malabsorption, low hemoglobin, and weight loss.
The analysis included 1849 patients with celiac disease, including 1460 women and 389 men, with a median age of nearly 50 years at diagnosis. While the vast majority of patients (nearly 1600) didn’t take an ARB, 120 started one before celiac disease diagnosis and 142 started one after diagnosis.
Overall, taking an ARB was associated with increased hazard ratios [HRs] for low hemoglobin, iron deficiency, diarrhea, and abdominal pain. There weren’t increased risks for weight loss, malabsorption, or vitamin deficiencies.
When excluding those who had an ARB prescription before diagnosis, the HRs remained significantly higher for low hemoglobin (HR, 1.98) and iron deficiency (HR, 1.72) for those who started an ARB after diagnosis.
“The use of angiotensin receptor blockers may be associated with worse outcomes in the setting of celiac disease, specifically persistent symptoms and possibly poor small bowel healing as evidenced by malabsorption,” Hujoel said.
Future studies could look specifically at losartan, which was the most common ARB prescribed in this analysis, she said. Other studies could also analyze different patient outcomes, whether patients were on a gluten-free diet, medication adherence, and recurrence or persistence of symptoms rather than initial occurrence. The associations between ARB use and celiac disease could shift among patients who are in remission, for instance.
“ARBs are some of the most widely used medications, so studies like these can help people to understand that they may have symptoms but not know it’s related to their medication. Public awareness of this fact is key,” said Patricia Jones, MD, a hepatologist and associate professor of clinical medicine at the University of Miami Miller School of Medicine, Miami. Jones co-moderated the plenary session on small intestine, functional, and liver research.
“There are many types of antihypertensives, so while ARBs are used often, other options are available if people have symptoms, especially if they have worsening symptoms with celiac disease,” she said. “It’s important to make changes in your practice.”

AI-Assisted Colonoscopy Linked to Higher Rate of Benign Lesion Removal
PHILADELPHIA — according to a study presented at the annual meeting of the American College of Gastroenterology (ACG).
In particular, AIAC led to a statistically and clinically significant increase in the proportion of exams that detected lesions that after resection were all found to be benign, compared with unassisted colonoscopy.
“The potential implications include increased procedural risks, as well as costs, such as pathology costs and other healthcare expenditures, without any additional colorectal cancer prevention benefit,” said lead author Tessa Herman, MD, chief resident of internal medicine at the University of Minnesota, Minneapolis, and Minneapolis Veterans Affairs Health Care System.
In a previous implementation trial at the Minneapolis VA Medical Center, Herman and colleagues compared ADR between a group of patients undergoing AIAC and a historical cohort of patients who had non–AI-assisted colonoscopy.
In this subsequent study, the research team conducted an ad hoc analysis of data from the previous trial to determine the proportion of colonoscopies for screening, surveillance, and positive fecal immunochemical tests which detect lesions that after resection are all found to be benign. They excluded colonoscopies conducted for diagnostic indications or inflammatory bowel disease, as well as incomplete colonoscopies, and for those with inadequate bowel preparation.
Overall, they studied 441 non-AIAC colonoscopies (between November 2022 and April 2023) and 599 AIAC colonoscopies (between May 2023 and October 2023). The groups were balanced, and there were no significant differences in patient demographics, endoscopists, AI technology, procedure time, or average number of polyps detected.
In the non-AIAC cohort, 37 cases (8.4%) had polypectomies that revealed only benign lesions, as compared with 74 cases (12.4%) in the AIAC cohort. The most common resected lesions were benign colonic mucosa, lymphoid aggregates, and hyperplastic polyps.
Applied to the 15 million colonoscopies conducted in the United States per year, the findings indicate that full adoption of AIAC could result in about 600,000 more colonoscopies in which only benign, nonadenomatous lesions are removed, compared with traditional colonoscopy, Herman said.
More study of AIAC is needed, said Daniel Pambianco, MD, managing partner of GastroHealth-Charlottesville in Virginia and the 2023 ACG president. “This technology is in a fledging stage, and the more data we have, the more helpful it’ll be to know if we’re removing the right lesions at a better rate.”
“There’s a hope that assistance will improve detection, removal of polyps, and ultimately, colon cancer,” added Pambianco, who comoderated the session on colorectal cancer prevention.
Future longitudinal studies should monitor both ADR and benign lesion resection rates with AIAC, and modeling studies could determine the benefits and costs of the technology, Herman said. In addition, development of hybrid CADe and computer-aided diagnosis systems could mitigate concerns about excessive benign lesion resection with AI tools.
Clinicians already are able to find colon mucosa that are polypoid or lymphoid aggregates during colonoscopy without AI assistance, said the session’s comoderator, Sita Chokhavatia, MD, AGAF, a gastroenterologist with Valley Medical Group in Ridgewood, New Jersey.
“Instead, we need a tool that can help us to not remove these polyps that are not neoplastic,” she said. “With future developments, we may be able to take it to the next step where the algorithm tells us that it’s benign and not to touch it.”
The study was named an ACG Newsworthy Abstract. Herman, Pambianco, and Chokhavatia reported no relevant disclosures.

In the non-AIAC cohort, 37 cases (8.4%) had polypectomies that revealed only benign lesions, as compared with 74 cases (12.4%) in the AIAC cohort. The most common resected lesions were benign colonic mucosa, lymphoid aggregates, and hyperplastic polyps.
Applied to the 15 million colonoscopies conducted in the United States per year, the findings indicate that full adoption of AIAC could result in about 600,000 more colonoscopies in which only benign, nonadenomatous lesions are removed, compared with traditional colonoscopy, Herman said.
More study of AIAC is needed, said Daniel Pambianco, MD, managing partner of GastroHealth-Charlottesville in Virginia and the 2023 ACG president. “This technology is in a fledging stage, and the more data we have, the more helpful it’ll be to know if we’re removing the right lesions at a better rate.”
“There’s a hope that assistance will improve detection, removal of polyps, and ultimately, colon cancer,” added Pambianco, who comoderated the session on colorectal cancer prevention.
Future longitudinal studies should monitor both ADR and benign lesion resection rates with AIAC, and modeling studies could determine the benefits and costs of the technology, Herman said. In addition, development of hybrid CADe and computer-aided diagnosis systems could mitigate concerns about excessive benign lesion resection with AI tools.
Clinicians already are able to find colon mucosa that are polypoid or lymphoid aggregates during colonoscopy without AI assistance, said the session’s comoderator, Sita Chokhavatia, MD, AGAF, a gastroenterologist with Valley Medical Group in Ridgewood, New Jersey.
“Instead, we need a tool that can help us to not remove these polyps that are not neoplastic,” she said. “With future developments, we may be able to take it to the next step where the algorithm tells us that it’s benign and not to touch it.”
The study was named an ACG Newsworthy Abstract. Herman, Pambianco, and Chokhavatia reported no relevant disclosures.
