FDA OKs Linzess for IBS With Constipation in Kids
, making it the first approved treatment for pediatric IBS-C.
The recommended dosage in pediatric patients is 145 mcg/d oral linaclotide.
Linaclotide is already approved in the US for IBS-C in adults, as well as functional constipation in children aged 6 years or older and chronic idiopathic constipation in adults.
IBS-C is common in children and adolescents. Symptoms include infrequent bowel movements with hard stools that can be difficult or painful to pass.
There is no known underlying organic cause and there are typically multiple contributing factors, the FDA said in a statement announcing the approval.
The efficacy of linaclotide to treat IBS-C in children aged 7 years or older was supported by extrapolation of efficacy from studies in adults and a 12-week double-blind, randomized, parallel-group trial in pediatric patients aged 7-17 years who met modified Rome III criteria for child/adolescent IBS-C, the FDA noted.
The primary endpoint was the proportion of patients who achieved at least a 30% reduction in abdominal pain and an increase of at least two naturally occurring bowel movements per week from baseline for at least 6 weeks of the 12-week treatment period.
The efficacy results in children with IBS-C were consistent with results seen in adults with IBS-C, with no new safety signals.
The most common side effect with linaclotide is diarrhea. If severe diarrhea occurs, linaclotide should be discontinued and rehydration started.
Linaclotide is contraindicated in children younger than 2 years. Patients with known or suspected mechanical gastrointestinal obstruction should not take linaclotide.

Is There Really a Cancer Epidemic in Younger Adults?
A global analysis challenged the notion that a rise in cancer is disproportionately affecting younger adults, finding instead that several cancer types previously seen rising in younger adults are also increasing in older adults.
More specifically, the analysis found that incidence rates for thyroid cancer, breast cancer, kidney cancer, endometrial cancer, and leukemia increased similarly in both younger and older adults in most countries over a 15-year period. Colorectal cancer (CRC) was the exception, where incidence rates increased in younger adults in most countries but only increased slightly in older adults in about half and decreased in about one quarter.
“Our findings suggest that whatever is triggering the rise in these cancers is more likely to be common across all age groups, rather than specific to cancers in the under 50s, since there were similar increases in younger and older adults,” Amy Berrington de González, DPhil, The Institute of Cancer Research, London, England, who led the study, said in a statement.
The authors of an editorial agreed, adding that the growing “concern about increasing cancer rates should recognize that this increase is not restricted to young adults but affects all generations.”
The study and editorial were published recently in Annals of Internal Medicine.
Data Defy Early-Onset Cancer Epidemic Narrative
A growing body of evidence suggests that cancer incidence rates are increasing among younger adults in many countries. However, studies tracking international trends have largely evaluated cancer incidence in younger adults without comparing these trends in older adults or analyses have focused the age comparison in individual countries, Berrington de González and colleagues explained.
To better understand cancer incidence trends across countries and age groups, the researchers evaluated cancer trends in 42 countries between 2003 and 2017, focusing on 13 cancer types previously reported to be climbing in adults younger than age 50 years.
The researchers found that incidence rates for six of the 13 cancer types increased among younger adults (aged 20-49 years) in more than three quarters of the countries studied.
The largest increase was in thyroid cancer (median average annual percentage change [AAPC], 3.57%), followed by kidney cancer (median AAPC, 2.21%), endometrial cancer (median AAPC, 1.66%), CRC (median AAPC, 1.45%), breast cancer (median AAPC, 0.89%), and leukemia (median AAPC, 0.78%).
But with the exception of CRC, incidence rates for these cancers increased to a similar degree in adults aged 50 years or older — with median AAPCs of 3% (vs 3.57%) for thyroid cancer, 1.65% (vs 2.21%) for kidney cancer, 1.20% (vs 1.66%) for endometrial cancer, 0.86% (vs 0.89%) for breast cancer, and 0.61% (vs 0.78%) for leukemia.
In older adults, CRC incidence rates only increased in about half the countries (median AAPC, 0.37%), and the annual percentage change was much greater in younger than older adults in nearly 70% of countries. CRC incidence rates in older individuals also decreased in nearly 25% of countries.
Why is CRC an apparent outlier?
“Bowel cancer screening not only helps detect cancer at earlier stages but also helps prevent cancer through the removal of premalignant lesions,” Berrington de González said. “This could be why bowel cancer cases seem to be rising faster in younger adults — we’re getting better at preventing them developing in older adults.”
The incidence of certain cancers also declined in younger adults. Specifically, rates of liver, oral, esophageal, and stomach cancers decreased in younger adults in more than half of countries assessed, with median AAPCs of -0.14% for liver, -0.42% for oral, -0.92% for esophageal, and -1.62% for stomach cancers.
Over half of countries also saw declining rates of stomach (median AAPC, -2.05%) and esophageal (median AAPC, -0.25%) cancers among older adults, while rates of liver and oral cancers increased in older individuals (median AAPC, 2.17% and 0.49%, respectively).
For gallbladder, pancreatic, and prostate cancers — three other cancers previously found to be increasing in younger adults — the researchers reported that incidence rates increased in younger adults in just over half of countries (median AAPCs, 3.2% for prostate cancer, 0.49% for gallbladder cancer, and 1% for pancreatic cancer). Incidence rates also often increased in older adults but to a lesser extent (median AAPCs, 0.75% for prostate cancer, -0.10% for gallbladder, and 0.96% for pancreatic cancer).
True Rise or Increased Scrutiny?
Why are cancer rates increasing?
“Understanding factors that contribute to the increase in incidence across the age spectrum was beyond the scope of the study,” editorialists Christopher Cann, MD, Fox Chase Cancer Center, and Efrat Dotan, MD, University of Pennsylvania Health System, both in Philadelphia, wrote.
Several studies have suggested that rising rates of obesity could help explain increasing cancer incidence, particularly in younger adults. In fact, “the cancers that we identified as increasing are all obesity-related cancers, including endometrial and kidney cancer,” Berrington de González said. However, so far, the evidence on this link remains unclear, she acknowledged.
Weighing in on the study, Gilbert Welch, MD, Brigham and Women’s Hospital, Boston, told this news organization that it’s “critically important” to distinguish between two explanations for rising cancer incidence.
There may be an increase in the true occurrence of clinically meaningful cancer, which “warrants investigation into biologic explanations, better treatment, and perhaps more testing,” Welch said.
But it may instead reflect changes in diagnostic scrutiny. “Simply put, whenever we doctors look harder for cancer, we find more,” Welch said. “And there are lots of ways to look harder: testing more people, testing people more frequently, using tests with increasing ability to detect small irregularities, and using lower diagnostic thresholds for labeling these as cancer.”
If increased incidence is the result of greater diagnostic scrutiny, searching for biologic causes is bound to be unproductive and more testing will only aggravate the problem, he explained.
Welch pointed out that the fastest rising cancer in both younger and older adults was thyroid cancer (AAPC, ≥ 3%), which is “exquisitely sensitive” to diagnostic scrutiny.
Take what happened in South Korea. Around 2000, the government of South Korea started a national screening program for breast, colon, and stomach cancers. Doctors and hospitals often added on ultrasound scans for thyroid cancer for a small additional fee.
“A decade later the rate of thyroid cancer diagnosis had increased 15-fold, turning what was once a rare cancer into the most common cancer in Korea,” Welch said. “But the death rate from thyroid cancer did not change. This was not an epidemic of disease; this was an epidemic of diagnosis.”
Welch also noted that the study authors and editorialists put the finding in perspective by explaining that, despite the rising rates of certain cancers in younger adults, cancer remains rare in these adults.
Welch highlighted that, for younger adults in the US, cancer death rates in young adults have cut in half over the last 30 years. “Cancer accounts for only 10% of deaths in young people in the US — and that number is falling,” Welch said.
The study was funded by the Institute of Cancer Research and the National Institutes of Health Intramural Research Program. Disclosures for authors and editorial writers are available with the original articles. Welch reported receiving royalties from three books including “Should I be tested for cancer?”

Polypectomy Best Practices Not Routinely Followed in US
, an analysis of more than 1.8 million colonoscopies found.
“We expected to find some variations in polypectomy technique, but the results were surprising; overall, cold snare usage was much lower than expected, given that this is the recommended method for removing most small polyps,” Seth Crockett, MD, MPH, AGAF, professor of medicine, Division of Gastroenterology and Hepatology, Oregon Health & Science University, Portland, told GI & Hepatology News.
The study was published in the October issue of The American Journal of Gastroenterology.
Using Gastroenterology Quality Improvement Consortium Registry data, Crockett and colleagues analyzed more than 1.8 million colonoscopies performed by 4601 endoscopists between 2019 and 2022 across 702 sites. All colonoscopies involved removal of polyps < 1 cm; lesions of this size are commonly found in screening colonoscopies, and detection is crucial to early cancer prevention.
The researchers found striking variation in polypectomy technique. Guideline-based cold snare polypectomy (CSP) was used in only 58% of cases (and as a single device in only 51%), whereas cold forceps polypectomy (CFP) accounted for 35% and hot snare polypectomy (HSP) for 11%.
The fact that CSP was used in fewer than 60% of cases represents “an important quality gap,” the authors wrote, adding that the fact that more than 10% of colonoscopies used HSP suggests that “some patients harboring low-risk lesions may be exposed to excess risk related to these practice variations.”
And while recommendations around the use of CFP are more nuanced (based largely on forceps type and polyp size), the “high frequency of CFP also suggests nonadherence to best practices,” they noted.
Gastroenterologists More Apt to Follow Guidance
Polypectomy technique varied by polyp type. CFP was more common in cases where only hyperplastic polyps were removed compared with cases with tubular adenomas (45% vs 30%, respectively). CSP use was highest in cases where only sessile serrated lesions were removed (66%) compared with cases with only tubular adenomas (61%) or hyperplastic polyps (37%).
There was also considerable variation by provider specialty.
Gastroenterologists (compared with non-GI specialists) used HSP less (4% vs 8%) and CSP more (40% vs 34%). Colonoscopies performed with GI fellows were more likely to use CFP (31% vs 21%) and less likely to use HSP (1% vs 5%) compared with colonoscopies without fellows.
“It was somewhat reassuring that colonoscopies performed by gastroenterologists were more likely to adhere to guideline recommendations, which suggests that dedicated endoscopy training is likely an important factor driving high-quality colonoscopy,” Crockett told GI & Hepatology News.
“Unexpectedly,” polypectomy technique also differed dramatically by geographic region, he said. CFP was used more than twice as often in the Northeast (31%) as in the Midwest (14%), whereas CSP was used more frequently in the Midwest (52%) than in the Northeast (32%).
“We suspect that much of the variation is related to differences in training, preferences, habits, and evolution of colonoscopy practice over time,” Crockett said. “More research is needed on the underlying drivers of this variation, and how differences in polypectomy technique impact both the safety and efficacy of colonoscopy to prevent colorectal cancer,” he said.
“As a specialty, we need to continue to work on disseminating guideline recommendations regarding colonoscopy quality, monitoring adherence to evidence-based practices, and working to address gaps in quality where they exist,” he added.
‘Concerning, Surprising, and Disappointing’
David Johnson, MD, professor of medicine and chief of gastroenterology at Eastern Virginia Medical School and Old Dominion University in Norfolk, called the results “concerning, surprising, and disappointing” and not consistent with the most current quality recommendations that advocate cold snare for most polyps less than 1 cm in size.
“Cold snare polypectomy has been shown not only to be more effective but also takes less time to perform, relative to cold biopsy,” said Johnson, who wasn’t involved in the study.
Johnson told GI & Hepatology News, “Inadequate lesion resection and variation in resection quality are major issues for colonoscopy quality. Those who perform colonoscopies need to be up-to-date with evidence-based quality standards — as well as held accountable if [there is] discordant practice — if we are to optimize the cancer prevention benefits of quality colonoscopy.”
Limitations of the current analysis include lack of extensive patient information and inability to further stratify polyps < 1 cm by size.
The study had no commercial funding. Crockett had no disclosures. Johnson disclosed serving as a director, officer, partner, employee, advisor, consultant, or trustee for ISOThrive.

“As a specialty, we need to continue to work on disseminating guideline recommendations regarding colonoscopy quality, monitoring adherence to evidence-based practices, and working to address gaps in quality where they exist,” he added.
‘Concerning, Surprising, and Disappointing’
David Johnson, MD, professor of medicine and chief of gastroenterology at Eastern Virginia Medical School and Old Dominion University in Norfolk, called the results “concerning, surprising, and disappointing” and not consistent with the most current quality recommendations that advocate cold snare for most polyps less than 1 cm in size.
“Cold snare polypectomy has been shown not only to be more effective but also takes less time to perform, relative to cold biopsy,” said Johnson, who wasn’t involved in the study.
Johnson told GI & Hepatology News, “Inadequate lesion resection and variation in resection quality are major issues for colonoscopy quality. Those who perform colonoscopies need to be up-to-date with evidence-based quality standards — as well as held accountable if [there is] discordant practice — if we are to optimize the cancer prevention benefits of quality colonoscopy.”
Limitations of the current analysis include lack of extensive patient information and inability to further stratify polyps < 1 cm by size.
The study had no commercial funding. Crockett had no disclosures. Johnson disclosed serving as a director, officer, partner, employee, advisor, consultant, or trustee for ISOThrive.

, an analysis of more than 1.8 million colonoscopies found.
“We expected to find some variations in polypectomy technique, but the results were surprising; overall, cold snare usage was much lower than expected, given that this is the recommended method for removing most small polyps,” Seth Crockett, MD, MPH, AGAF, professor of medicine, Division of Gastroenterology and Hepatology, Oregon Health & Science University, Portland, told GI & Hepatology News.
The study was published in the October issue of The American Journal of Gastroenterology.
Using Gastroenterology Quality Improvement Consortium Registry data, Crockett and colleagues analyzed more than 1.8 million colonoscopies performed by 4601 endoscopists between 2019 and 2022 across 702 sites. All colonoscopies involved removal of polyps < 1 cm; lesions of this size are commonly found in screening colonoscopies, and detection is crucial to early cancer prevention.
The researchers found striking variation in polypectomy technique. Guideline-based cold snare polypectomy (CSP) was used in only 58% of cases (and as a single device in only 51%), whereas cold forceps polypectomy (CFP) accounted for 35% and hot snare polypectomy (HSP) for 11%.
The fact that CSP was used in fewer than 60% of cases represents “an important quality gap,” the authors wrote, adding that the fact that more than 10% of colonoscopies used HSP suggests that “some patients harboring low-risk lesions may be exposed to excess risk related to these practice variations.”
And while recommendations around the use of CFP are more nuanced (based largely on forceps type and polyp size), the “high frequency of CFP also suggests nonadherence to best practices,” they noted.
Gastroenterologists More Apt to Follow Guidance
Polypectomy technique varied by polyp type. CFP was more common in cases where only hyperplastic polyps were removed compared with cases with tubular adenomas (45% vs 30%, respectively). CSP use was highest in cases where only sessile serrated lesions were removed (66%) compared with cases with only tubular adenomas (61%) or hyperplastic polyps (37%).
There was also considerable variation by provider specialty.
Gastroenterologists (compared with non-GI specialists) used HSP less (4% vs 8%) and CSP more (40% vs 34%). Colonoscopies performed with GI fellows were more likely to use CFP (31% vs 21%) and less likely to use HSP (1% vs 5%) compared with colonoscopies without fellows.
“It was somewhat reassuring that colonoscopies performed by gastroenterologists were more likely to adhere to guideline recommendations, which suggests that dedicated endoscopy training is likely an important factor driving high-quality colonoscopy,” Crockett told GI & Hepatology News.
“Unexpectedly,” polypectomy technique also differed dramatically by geographic region, he said. CFP was used more than twice as often in the Northeast (31%) as in the Midwest (14%), whereas CSP was used more frequently in the Midwest (52%) than in the Northeast (32%).
“We suspect that much of the variation is related to differences in training, preferences, habits, and evolution of colonoscopy practice over time,” Crockett said. “More research is needed on the underlying drivers of this variation, and how differences in polypectomy technique impact both the safety and efficacy of colonoscopy to prevent colorectal cancer,” he said.
“As a specialty, we need to continue to work on disseminating guideline recommendations regarding colonoscopy quality, monitoring adherence to evidence-based practices, and working to address gaps in quality where they exist,” he added.

FDA Grants Rinvoq Updated Indication in IBD
The updated indication allows for starting upadacitinib before a TNF blocker in patients for whom use of these treatments is clinically inadvisable and who have received at least one approved systemic therapy, the company said in a statement.
Previously, upadacitinib was indicated only in adults with moderately to severely active ulcerative colitis or Crohn’s disease who had an inadequate response or intolerance to one or more TNF blockers.
“Ulcerative colitis and Crohn’s disease can impact every aspect of a patient’s life. This label update gives healthcare providers the option to prescribe Rinvoq for patients with moderately to severely active inflammatory bowel disease after the use of one approved systemic therapy if TNF blockers are deemed clinically inadvisable by the prescribing physician,” Kori Wallace, MD, PhD, vice president and global head of immunology clinical development at AbbVie, said in the statement.

Novel Agent Promising for Refractory Ulcerative Colitis
The findings, from the ABTECT-1 and ABTECT-2 phase 3 induction trials, were presented in two separate late-breaking presentations at United European Gastroenterology (UEG) Week 2025 in Berlin, Germany.
“These trials enrolled a broad spectrum of participants, including one of the most severe and refractory populations evaluated to date in a phase 3 UC trial, with about 60% of patients across the pooled dataset having a Mayo endoscopic subscore of 3 — the highest level of UC endoscopic disease activity,” study investigator Marla Dubinsky, MD, gastroenterologist and co-director of the IBD Center at Mount Sinai in New York City, told GI & Hepatology News.
“Even within this challenging population, obefazimod achieved the primary endpoint of clinical remission and all key secondary endpoints, including endoscopic improvement, after just 8 weeks of therapy,” Dubinsky said.
This suggests that obefazimod may serve as both an early advanced therapy option and a much-needed alternative for patients with moderately to severely active UC who have failed multiple biologics and JAK inhibitors, with few choices left short of colectomy, she added.
Study Details
Obefazimod is an investigational oral, potentially first-in-class drug that enhances expression of microRNA-124, resulting in regulation of the inflammatory response and restoring mucosal homeostasis in UC.
The ABTECT-1 and ABTECT-2 were identically designed induction trials enrolling a total of 1272 patients with moderately to severely active UC who had inadequate response, loss of response, or intolerance to at least one prior therapy (with no upper limit), including corticosteroids, immunosuppressants, biologics, S1P receptor modulators, and/or JAK inhibitors. Participants were randomly assigned in a 2:1:1 ratio to receive obefazimod 50 mg or 25 mg or placebo once daily for 8 weeks.
In ABTECT-1, obefazimod 50 mg and 25 mg met the primary endpoint of clinical remission, with 22% of patients in the 50-mg group and 24% in the 25-mg group achieving clinical remission at 8 weeks compared with 2.5% of the placebo group.
The effect sizes for clinical remission were 21% for the 25-mg dose and 19% for the 50-mg dose, reported Bruce E. Sands, MD, MS, AGAF, professor of medicine at Icahn School of Medicine at Mount Sinai and chief in the Division of Gastroenterology at Mount Sinai Health System in New York City.
In ABTECT-2, the 50-mg dose met the primary endpoint of clinical remission, with 20% of patients achieving remission compared with 11% in the 25-mg group and 6.3% in the placebo group.
The effect sizes for clinical remission in ABTECT-2 were “a bit smaller” (13% for the 50-mg dose and 5% for the 25-mg dose) “because the absolute efficacy of 50 mg in this study was a little bit lower, and the placebo response rate was a little bit higher at 6.3%, and so accordingly, the 25-mg dose did not achieve statistical significance,” Sands explained.
Both doses of obefazimod met all secondary endpoints in ABTECT-1 and the 50-mg dose achieved all secondary endpoints in ABTECT-2. Secondary endpoints included clinical response, endoscopic improvement, symptomatic remission, and histo-endoscopic mucosal improvement.
Pooled data across the two studies showed that both doses achieved “clinically meaningful improvements across all efficacy points,” Sands noted.
Notably, obefazimod 50 mg once daily achieved “consistent and clinically meaningful improvements” regardless of prior failure of advanced therapy, and both doses performed similarly well in the subgroup with no prior failure of advanced therapy, Silvio Danese, MD, PhD, with Vita-Salute San Raffaele University, Milan, Italy, reported in a separate presentation.
Adverse Events ‘Not a Barrier to Treatment’
Pooled data across the two studies showed no signal for serious, severe, or opportunistic infections or malignancies.
The most commonly reported treatment-emergent adverse event was headache, reported in 24% and 16% of patients taking obefazimod 50 mg and 25 mg, respectively, vs 6% of those taking placebo. Headaches were mild, transient, and short-lasting and “not a barrier to treatment, as evidenced by the low discontinuation (< 1%),” Sands noted.
“Because this is a safe agent and it’s an oral agent and convenient, I think the drug could be used early in the course of the disease, before advanced therapy or after failure of advanced therapies, even multiple advanced therapies,” Sands said.
“Of course, we’ll have to see what the maintenance data show. But we have a long experience from the phase 2a and 2b long-term extension treatments, and the durability seems to be quite good,” Sands cautioned.
Abivax CEO Marc de Garidel, MBA, told GI & Hepatology News that the company will share “top-line data” from the 44-week maintenance study evaluating obefazimod in UC in the second quarter of 2026.
“If positive, the data will support a potential NDA [New Drug Application] submission in the second half of 2026,” de Garidel said.
‘Promising Data’
Ashwin Ananthakrishnan, MBBS, MPH, AGAF, associate professor of medicine at Harvard Medical School and a gastroenterologist at Massachusetts General Hospital, Boston, who wasn’t involved in the study, was impressed.
“I think this is very promising data from an important study. This is an entirely novel mechanism of action in ulcerative colitis,” Ananthakrishnan told GI & Hepatology News.
“While we have many treatments available, there are still a large number of patients who do not respond to existing treatment mechanisms,” he said. These trials “consisted of a large number of very refractory patients (severe endoscopic disease or multiple prior mechanism failures). That it works well in this population is very promising (and clinically impactful).”
It would be a “welcome addition to the armamentarium,” he added.
The study was funded by Abivax. Several study authors disclosed having financial relationships with the company. Ananthakrishnan reported having no disclosures.

Half of Patients Skip Repeat Stool Tests for CRC Screening
A large real-world study found that
Among those who did repeat the test, the average delay was 3 months before COVID and increased to 5 months during the pandemic, the authors reported in BMJ Public Health.
“Stool tests are relatively easy to complete at home and mailed for testing, and they are inexpensive, but they must be completed annually. In contrast, colonoscopies are more invasive and require more time away from work but only need to be repeated every 5-10 years,” Staci J Wendt, PhD, director, health research accelerator, Providence Research Network, Providence, Rhode Island, told GI & Hepatology News.
In the end, “the best colorectal cancer screening test is the one that gets done,” Wendt said.
“This is why we stress the importance of patients and their doctor having these discussions together and deciding which screening is the most preferred method for the individual patient,” she added.
Stool Tests Gaining Traction
Adults are increasingly turning to at-home stool tests for CRC screening — a trend that accelerated during the pandemic. Yet, there is limited data on whether patients undergo repeat stool tests following initial negative test results.
Wendt and her colleagues documented rates of repeat preventative stool tests by analyzing electronic medical records from Providence St Joseph Health, a large health system with 51 hospitals and over 1000 clinics across seven western US states.
They divided their analysis into two periods based on the onset of the pandemic. The pre-COVID onset period spanned January 2018 to February 2020 and the post-COVID period spanned March 2020 to February 2022.
“The pandemic is a salient time to conduct this study because it resulted in a dramatic decrease in colonoscopies, which were partially replaced by stool tests. This partial replacement of colonoscopies by stool tests has led other studies to conclude that stool tests mitigated gaps in CRC screening during the pandemic. But gaps may persist if patients do not undergo repeat testing,” the study team explained.
Their sample included 403,085 patients. Among those with an initial negative stool test, the share who obtained a timely repeat screening ranged from 38% to 49% across the study years, confirming that “most patients do not undergo the recommended repeat screening after their initial stool test,” the researchers said.
Among adults who do a repeat test, delays were common. The average lag to the follow-up test was 3months on average, increasing to about 5 months amid COVID — almost half as long as the preventative screening period of stool tests (12 months).
“These gaps could delay detection of CRC and subsequent treatment, potentially resulting in higher mortality. These gaps are particularly important as more and more patients use stool tests instead of colonoscopes for CRC screening,” the researchers wrote.
Screening patterns shifted markedly during the pandemic.
Not surprisingly, the volume of colonoscopies declined substantially after the onset of the pandemic and stayed low through the study’s end. In contrast, the volume of at-home stool tests was increasing before the pandemic and accelerated during the pandemic.
“Given this increase in stool tests, it will be increasingly important to focus on improving long-term adherence to screening through outreach, policies and programs,” the researchers said.
A Multilevel Approach
Wendt said health systems that are incorporating proactive measures like sending stool kits to patients who are eligible for screening, should ensure that these screening kits and information are sent annually and that it is stressed that the screening must happen every year.
Reached for comment, Aasma Shaukat, MD, MPH, AGAF, director of outcomes research, Division of Gastroenterology and Hepatology, NYU Langone Health, New York City, who wasn’t involved in the study, said the poor adherence to repeat stool tests for CRC screening seen in this study is “not surprising.”
“We know that adherence goes down with each consecutive screening round and what is really needed is an organized program to keep the level of adherence up,” Shaukat told GI & Hepatology News.
Shaukat agreed that boosting adherence to stool tests requires a “multilevel approach.”
She cited the success of the CRC screening program implemented across Kaiser Permanente Northern California. The program includes proactive and targeted outreach to members who are overdue for screening and mailed fecal immunochemical test kits for at-home use.
As reported previously by GI & Hepatology News, the program has made a huge difference in CRC incidence, deaths, and racial disparities.
The program has doubled the proportion of people up to date with screening. And, within about 10 years, cancer rates were cut by a third, deaths were halved and largely eliminated long-standing differences by race and ethnicity.
The study had no commercial funding. Wendt and Shaukat declared having no relevant disclosures.

Screening patterns shifted markedly during the pandemic.
Not surprisingly, the volume of colonoscopies declined substantially after the onset of the pandemic and stayed low through the study’s end. In contrast, the volume of at-home stool tests was increasing before the pandemic and accelerated during the pandemic.
“Given this increase in stool tests, it will be increasingly important to focus on improving long-term adherence to screening through outreach, policies and programs,” the researchers said.
A Multilevel Approach
Wendt said health systems that are incorporating proactive measures like sending stool kits to patients who are eligible for screening, should ensure that these screening kits and information are sent annually and that it is stressed that the screening must happen every year.
Reached for comment, Aasma Shaukat, MD, MPH, AGAF, director of outcomes research, Division of Gastroenterology and Hepatology, NYU Langone Health, New York City, who wasn’t involved in the study, said the poor adherence to repeat stool tests for CRC screening seen in this study is “not surprising.”
“We know that adherence goes down with each consecutive screening round and what is really needed is an organized program to keep the level of adherence up,” Shaukat told GI & Hepatology News.
Shaukat agreed that boosting adherence to stool tests requires a “multilevel approach.”
She cited the success of the CRC screening program implemented across Kaiser Permanente Northern California. The program includes proactive and targeted outreach to members who are overdue for screening and mailed fecal immunochemical test kits for at-home use.
As reported previously by GI & Hepatology News, the program has made a huge difference in CRC incidence, deaths, and racial disparities.
The program has doubled the proportion of people up to date with screening. And, within about 10 years, cancer rates were cut by a third, deaths were halved and largely eliminated long-standing differences by race and ethnicity.
The study had no commercial funding. Wendt and Shaukat declared having no relevant disclosures.

A large real-world study found that
Among those who did repeat the test, the average delay was 3 months before COVID and increased to 5 months during the pandemic, the authors reported in BMJ Public Health.
“Stool tests are relatively easy to complete at home and mailed for testing, and they are inexpensive, but they must be completed annually. In contrast, colonoscopies are more invasive and require more time away from work but only need to be repeated every 5-10 years,” Staci J Wendt, PhD, director, health research accelerator, Providence Research Network, Providence, Rhode Island, told GI & Hepatology News.
In the end, “the best colorectal cancer screening test is the one that gets done,” Wendt said.
“This is why we stress the importance of patients and their doctor having these discussions together and deciding which screening is the most preferred method for the individual patient,” she added.
Stool Tests Gaining Traction
Adults are increasingly turning to at-home stool tests for CRC screening — a trend that accelerated during the pandemic. Yet, there is limited data on whether patients undergo repeat stool tests following initial negative test results.
Wendt and her colleagues documented rates of repeat preventative stool tests by analyzing electronic medical records from Providence St Joseph Health, a large health system with 51 hospitals and over 1000 clinics across seven western US states.
They divided their analysis into two periods based on the onset of the pandemic. The pre-COVID onset period spanned January 2018 to February 2020 and the post-COVID period spanned March 2020 to February 2022.
“The pandemic is a salient time to conduct this study because it resulted in a dramatic decrease in colonoscopies, which were partially replaced by stool tests. This partial replacement of colonoscopies by stool tests has led other studies to conclude that stool tests mitigated gaps in CRC screening during the pandemic. But gaps may persist if patients do not undergo repeat testing,” the study team explained.
Their sample included 403,085 patients. Among those with an initial negative stool test, the share who obtained a timely repeat screening ranged from 38% to 49% across the study years, confirming that “most patients do not undergo the recommended repeat screening after their initial stool test,” the researchers said.
Among adults who do a repeat test, delays were common. The average lag to the follow-up test was 3months on average, increasing to about 5 months amid COVID — almost half as long as the preventative screening period of stool tests (12 months).

Diet Drinks Harder on the Liver Than Sugary Drinks?
BERLIN — Diet drinks may not be “healthier” than sugary drinks when it comes to liver health.
In fact, low- or artificially sweetened beverages were actually linked to a higher risk for MASLD than sugar-laden drinks, even at modest intake levels such as a single can per day.
“These findings challenge the common perception that these drinks are harmless and highlight the need to reconsider their role in diet and liver health, especially as MASLD emerges as a global health concern,” lead author Lihe Liu, a graduate student in the Department of Gastroenterology at The First Affiliated Hospital of Soochow University in Suzhou, China, said in a news release.
She presented her research at the United European Gastroenterology (UEG) Week 2025 in Berlin, Germany.
Stick With Water
MASLD affects 38% of the global population and has become a leading cause of cirrhosis, liver cancer, and liver-related death. Lifestyle modification remains “a cornerstone” of MASLD management. Current guidelines advise against SSBs, but the evidence regarding LNSSBs remains “limited,” Liu explained in her presentation.
To investigate, the researchers analyzed data of 123,788 UK Biobank participants without liver disease at baseline who were followed for an average of 10.3 years. Beverage consumption was assessed through repeated 24-hour dietary questionnaires using the question: “How many glasses, cans, or cartons containing 250 mL (roughly 250 g) of SSBs or LNSSBs did you drink yesterday?”
Intake was averaged across at least two recalls, and participants were grouped into three intake categories: none, more than 0 to one serving per day, or more than one serving per day.
The primary outcome was incident MASLD, and secondary outcomes included liver-related mortality and liver fat content measured using MRI-derived proton density fat fraction.
In the fully adjusted multivariable Cox model, compared with no consumption, consuming more than one serving of LNSSBs daily was associated with a 60% higher risk for MASLD (hazard ratio [HR], 1.599). The level of consumption of SSBs was associated with a 50% higher risk (HR, 1.469).
Consuming more than one serving of LNSSBs daily was also associated with a higher risk for severe liver outcomes (HR, 1.555), while SSBs showed no significant association after adjustment.
Neither SSBs nor LNSSBs showed significant associations with all-cause mortality in fully adjusted models.
Substituting either beverage with water reduced the risk for MASLD by 12.8% for SSBs and 15.2% for LNSSBs, Liu reported.
Both beverage types were positively associated with higher liver fat content. Consumption of more than one serving of SSBs and LNSSBs daily was associated with about 5% and 7% higher liver fat levels, respectively, than nonconsumption.
“The higher sugar content in SSBs can cause rapid spikes in blood glucose and insulin, promote weight gain, and increase uric acid levels, all of which contribute to liver fat accumulation. LNSSBs, on the other hand, may affect liver health by altering the gut microbiome, disrupting the feeling of fullness, driving sweet cravings, and even stimulating insulin secretion,” Liu said.
“The safest approach is to limit both sugar-sweetened and artificially sweetened drinks. Water remains the best choice as it removes the metabolic burden and prevents fat accumulation in the liver, whilst hydrating the body,” she concluded.
More Study Needed
Reached for comment, Sujit V. Janardhan, MD, PhD, director of the steatotic liver disease program, Rush University Medical Center, Chicago, said the findings “certainly should cause one to take pause from the popular notion that diet or non-sugar-sweetened beverages are healthier than their sugar-sweetened alternatives.”
He cautioned, however, that it would be “important to confirm confounders are adequately addressed in this large population-based study.”
“We must better understand what other exposure and characteristics were present in patients who had increased intake of non-sugar-sweetened beverages,” Janardhan told GI & Hepatology News.
“For example, it’s possible people who drank more non-sugar-sweetened beverages had more cardiovascular or metabolic risk factors (which prompted them to switch to the ‘diet’ alternative) and that it is these comorbidities that drove an association with increased MASLD incidence and liver-related mortality,” Janardhan noted.
“If there is one finding that seems easy to take away from this study, it’s that people who drank more water in place of sweetened beverages had reduced risk of MASLD,” he told GI & Hepatology News.
Therefore, while awaiting results of mechanistic studies and careful confounder analysis, “plain old boring water is your best bet,” Janardhan said.
The study had no specific funding. Liu and Janardhan had no relevant disclosures.

FDA OKs Simponi for Pediatric Ulcerative Colitis
Of the more than 1 million people in the US living with UC, roughly 20% are children, Johnson & Johnson noted in a statement announcing approval.
The pediatric indication for golimumab in UC was supported by the open-label PURSUIT 2 phase 3 study evaluating the efficacy, safety, and pharmacokinetics of subcutaneously administered golimumab in children aged 2 years and older with moderately to severely active UC.
In the trial, the primary endpoint of clinical remission at week 6 was achieved by 32% of children. Clinical remission was defined as a Mayo score ≤ 2 points, with no individual subscore > 1.
The secondary endpoints of clinical response at week 6 was achieved by 58%, and endoscopic improvement at week 6 was achieved by 40% of patients receiving golimumab.
Clinical response was defined as a decrease from baseline in the Mayo score by > 30% and > 3 points, with either a decrease from baseline in the rectal bleeding subscore of > 1 or a rectal bleeding subscore of 0 or 1. Endoscopic remission was defined as an endoscopy subscore of 0 or 1 based on local endoscopy.
Among children treated with golimumab who were in clinical remission at 6 weeks, 57% maintained clinical remission of symptoms at week 54. Safety results in children were consistent with clinical trials of golimumab in adults with UC, the company said.
The recommended dose of golimumab for pediatric patients weighing at least 40 kg is 200 mg at week 0, followed by 100 mg at weeks 2, 6, and every 4 weeks thereafter; for those weighing at least 15 kg to less than 40 kg, golimumab is administered at 100 mg at week 0, followed by 50 mg at weeks 2, 6, and every 4 weeks thereafter.
Golimumab is administered as a prefilled syringe; children aged 12 and older can self-administer it after proper training by a healthcare provider.
This is the first pediatric approval for golimumab, which is already approved for four indications, including adults living with moderate-to-severe rheumatoid arthritis, active psoriatic arthritis, active ankylosing spondylitis, and moderately to severely active UC.
Full prescribing information and medication guide is available online.

Withdrawing Anti-TNF in IBD Remission: New Data
In the Spanish EXIT study, anti-TNF withdrawal in selected patients with IBD in clinical, endoscopic, and radiological remission had no impact on sustained clinical remission at 1 year, although objective markers of activity were higher in patients who stopped treatment.
The discontinuation of anti-TNF treatment “could be considered as an option” for a selected group of patients, said the authors led by Javier Gisbert, MD, PhD, with Autonomous University of Madrid.
However, the higher proportion of patients with elevated fecal calprotectin and significant endoscopic lesions at the end of follow-up “calls for caution and should be considered when discontinuing treatment in patients,” Gisbert and colleagues concluded.
The EXIT study results were published in the journal Gut (2025 Feb. doi: 10.1136/gutjnl-2024-333385).
Risky Business?
Anti-TNF drugs have reshaped IBD treatment but bring infection risks and costs, prompting interest in planned withdrawal after stable remission.
Yet prior evidence has been mixed. A meta-analysis of 27 studies suggested higher relapse after stopping anti-TNF therapy. However, the results were heterogeneous and most of the studies were retrospective, with a low number of patients and without a control group to compare with.
Clinical trials that have assessed the risk for relapse after discontinuation of anti-TNF therapy generally favored maintenance but had notable limitations.
The EXIT trial was conducted at 33 IBD units across Spain. A total of 140 patients in steroid-free clinical remission for ≥ 6 months on standard-dose infliximab or adalimumab were randomized (1:1) to either continue anti-TNF or switch to placebo matched to the drug they had been taking. All patients continued on immunomodulator therapy.
At 1 year, the proportion of patients with sustained clinical remission (primary outcome) was similar between patients who continued anti-TNF therapy and peers who stopped the medication (76% and 84%, respectively).
However, the proportion of patients with significant endoscopic lesions at the end of follow-up was higher in those who withdrew anti-TNF therapy (19% vs 8.5%; P = .01). Elevated fecal calprotectin (> 250 µg/g) was more common after withdrawal (33% vs 13%; P = .01).
Fecal calprotectin > 250 µg/g at baseline predicted lower odds of sustained remission and higher risk for losing remission — and was the only factor associated with lower likelihood of sustained remission.
Common Clinical Question
“When a patient starts an advanced biologic therapy, they often ask — will I be able to stop it?” Jean-Frederic Colombel, MD, director of the Inflammatory Bowel Disease Clinical Center at the Icahn School of Medicine at Mount Sinai, New York City, who wasn’t involved in the study, told GI & Hepatology News.
Generally speaking, Colombel said he tells patients, “If the drug is working well and you are in deep remission, they should try to avoid stopping because there is a risk of relapse. And with relapse, we never know if the drug will work again and maybe we’ll have to switch to another medication.”
“It’s an individualized discussion and decision and patients who do opt to stop [anti-TNF therapy] need to be monitored closely,” Colombel said.
Colombel cautioned that the study had a relatively short 1-year follow-up and those that stopped anti-TNF therapy had evidence of recurrent inflammation.
“Even though it didn’t translate yet to clinical relapse, there were more patients with subclinical active disease in the group that stopped as compared to the group that continued,” Colombel said.
He also noted that in the SPARE trial of patients with Crohn’s disease in clinical remission, patients who stopped infliximab had a higher risk for relapse compared with patients who stopped azathioprine and those who continued the combination therapy.
The EXIT study was supported by grants from Instituto de Salud Carlos III, Grupo Español de Trabajo en Enfermedad de Crohn y Colitis Ulcerosa and AbbVie. Gisbert reported serving as speaker, consultant, and advisory member for or receiving research funding from MSD, AbbVie, Pfizer, Kern Pharma, Biogen, Mylan, Takeda, Janssen, Roche, Sandoz, Celgene/Bristol Myers, Gilead/Galapagos, Lilly, Ferring, Faes Farma, Shire Pharmaceuticals, Dr. Falk Pharma, Tillotts Pharma, Chiesi, Casen Fleet, Gebro Pharma, Otsuka Pharmaceutical, Norgine and Vifor Pharma. Colombel had no relevant disclosures.

“When a patient starts an advanced biologic therapy, they often ask — will I be able to stop it?” Jean-Frederic Colombel, MD, director of the Inflammatory Bowel Disease Clinical Center at the Icahn School of Medicine at Mount Sinai, New York City, who wasn’t involved in the study, told GI & Hepatology News.
Generally speaking, Colombel said he tells patients, “If the drug is working well and you are in deep remission, they should try to avoid stopping because there is a risk of relapse. And with relapse, we never know if the drug will work again and maybe we’ll have to switch to another medication.”
“It’s an individualized discussion and decision and patients who do opt to stop [anti-TNF therapy] need to be monitored closely,” Colombel said.
Colombel cautioned that the study had a relatively short 1-year follow-up and those that stopped anti-TNF therapy had evidence of recurrent inflammation.
“Even though it didn’t translate yet to clinical relapse, there were more patients with subclinical active disease in the group that stopped as compared to the group that continued,” Colombel said.
He also noted that in the SPARE trial of patients with Crohn’s disease in clinical remission, patients who stopped infliximab had a higher risk for relapse compared with patients who stopped azathioprine and those who continued the combination therapy.

In the Spanish EXIT study, anti-TNF withdrawal in selected patients with IBD in clinical, endoscopic, and radiological remission had no impact on sustained clinical remission at 1 year, although objective markers of activity were higher in patients who stopped treatment.
The discontinuation of anti-TNF treatment “could be considered as an option” for a selected group of patients, said the authors led by Javier Gisbert, MD, PhD, with Autonomous University of Madrid.
However, the higher proportion of patients with elevated fecal calprotectin and significant endoscopic lesions at the end of follow-up “calls for caution and should be considered when discontinuing treatment in patients,” Gisbert and colleagues concluded.
The EXIT study results were published in the journal Gut (2025 Feb. doi: 10.1136/gutjnl-2024-333385).
Risky Business?
Anti-TNF drugs have reshaped IBD treatment but bring infection risks and costs, prompting interest in planned withdrawal after stable remission.
Yet prior evidence has been mixed. A meta-analysis of 27 studies suggested higher relapse after stopping anti-TNF therapy. However, the results were heterogeneous and most of the studies were retrospective, with a low number of patients and without a control group to compare with.
Clinical trials that have assessed the risk for relapse after discontinuation of anti-TNF therapy generally favored maintenance but had notable limitations.
The EXIT trial was conducted at 33 IBD units across Spain. A total of 140 patients in steroid-free clinical remission for ≥ 6 months on standard-dose infliximab or adalimumab were randomized (1:1) to either continue anti-TNF or switch to placebo matched to the drug they had been taking. All patients continued on immunomodulator therapy.
At 1 year, the proportion of patients with sustained clinical remission (primary outcome) was similar between patients who continued anti-TNF therapy and peers who stopped the medication (76% and 84%, respectively).
However, the proportion of patients with significant endoscopic lesions at the end of follow-up was higher in those who withdrew anti-TNF therapy (19% vs 8.5%; P = .01). Elevated fecal calprotectin (> 250 µg/g) was more common after withdrawal (33% vs 13%; P = .01).
Fecal calprotectin > 250 µg/g at baseline predicted lower odds of sustained remission and higher risk for losing remission — and was the only factor associated with lower likelihood of sustained remission.

How Chronic Stress Disrupts the Gut Microbiome
Chronic psychological stress is common. A 2023 survey revealed that about one quarter of US adults reported high stress levels, and three quarters reported that chronic stress affects their daily lives.
Emerging evidence suggests that chronic stress not only exacts a high toll on mental health but also can wreak havoc on all levels of gastrointestinal (GI) functioning, all the way down to the microbiome.
Aasma Shaukat, MD, MPH, AGAF, gastroenterologist with NYU Langone Health and director of GI Outcomes Research, Gastroenterology at NYU Grossman School of Medicine in New York City, said in an interview with GI & Hepatology News.
“This basically means that the normal balance of microorganisms that essentially we think are beneficial gets reduced, and the colonies considered to be more harmful proliferate,” she explained.
What Does the Science Tell Us?
Numerous studies published in the past 5 years have linked chronic stress to modest but reproducible shifts in the composition of the microbiome.
A study of frontline healthcare workers during COVID-19 revealed that the pandemic was associated with significant depression, anxiety, and stress, as well as gut dysbiosis that persisted for at least half a year.
Notably, healthcare workers had low gut alpha diversity, indicating a less resilient and diverse microbiome, a state often associated with dysbiosis and increased risk for various diseases and negative health outcomes.
A two-cohort study of healthy adults found higher alpha diversity in those reporting low stress levels. It also found a link between stress and enriched levels of Escherichia/Shigella, an overgrowth of which has been linked to various conditions, including inflammatory bowel disease.
In addition, a 2023 systematic review of human studies concluded that stress is associated with changes in specific genera — namely reductions in gut-healthy Lachnospira/Lachnospiraceae and Phascolarctobacterium, which produce beneficial short-chain fatty acids that support the health of the intestinal lining and modulate the immune system.
Stress during specific life stages also appears to alter the gut microbiome.
For example, in a study of postpartum women, those at an increased risk for parenting stress showed lower alpha diversity on the Shannon diversity index.
Research involving mother-child pairs tied adversity — such as maltreatment of the mother during her childhood, prenatal anxiety, and hardship in the child’s early life — to distinct microbiome profiles in 2-year-olds, supporting a stress-microbiome pathway relevant to socioemotional outcomes, the authors said.
Emerging evidence indicates a link between the gut microbiome and posttraumatic stress disorder (PTSD).
A recent systematic review found differences in gut microbial taxa between individuals with PTSD and trauma-exposed controls without PTSD. A separate analysis pointed to a potential causal impact of gut microbiomes on the development of PTSD.
Mechanisms Behind the Link
Stress interferes with the brain’s production of neurotransmitters, such as serotonin, which controls anxiety, mood, sleep, and many other functions in the brain, Shaukat told GI & Hepatology News.
“But serotonin also crosses the blood-brain barrier, and actually, the gut has more serotonin receptors than the brain, so an imbalance of serotonin can actually affect the gut microbiome through signaling at the neurotransmitter level,” Shaukat explained.
Stress can also affect sleep, and sleep itself has regulatory properties for gut bacteria, Shaukat noted.
“Stress also lowers our immunity, and this can make the gut barrier susceptible or permeable to bacterial toxins that can pass through and breach the gut barrier and be released into the bloodstream, which can trigger inflammation,” Shaukat explained.
Implications for Patient Care
The gut-brain-microbiome axis remains an emerging field of study. “We’re learning more and more about this, and we need to because the microbial colonies are so diverse and we haven’t nailed it down yet,” Shaukat said.
In the meantime, what can clinicians tell patients?
Aside from managing stress, which “is easier said than done,” patients can improve their diet, Shaukat said.
“What we tell patients is to essentially increase their intake of gut-friendly foods that preferentially grow the bacterial colonies that are beneficial for us,” Shaukat said. This includes fermented foods, yogurt, kimchi, chia seeds, kombucha, pickled vegetables, and whole grains.
A recent randomized controlled trial of healthy adults found a “psychobiotic diet” — a diet high in prebiotic and fermented foods — was associated with less perceived stress and subtle beneficial shifts in microbial composition.
“These foods can help keep the gut in good health and may actually also reduce or mitigate some of the effects of stress,” Shaukat said.
“Eating well is something I think we should all think about and maybe prioritize when we’re going through a stressful situation or looking to kind of mitigate the effects of stress and the anxiety and depression it can cause,” she advised.
Shaukat said she also encourages patients to engage in regular physical activity, which benefits the gut microbiome by helping to regulate gut motility. Exercise can also boost mood and help relieve stress.
“A balanced Mediterranean diet and regular activity is truly the secret for gut health,” Shaukat said.
Patients may be tempted by the probiotic supplements lining drugstore shelves, but there “isn’t great evidence for probiotic supplements,” she said. “What we can get from dietary sources far outweighs what can be put in a pill.”
Shaukat disclosed having no relevant disclosures.
