STOCKHOLM — A proactive treat-to-target strategy in patients with Crohn’s disease (CD) who are in remission but are considered to be high risk as determined by video capsule endoscopy was superior for prevention of clinical flare within the next 2 years compared with continued standard care, a new study showed.

Capsule endoscopy reveals small-intestinal inflammation in over 70% of patients with CD who are in clinical remission, said Shomron Ben-Horin, MD, from Sheba Medical Center, Tel Aviv University, Tel Aviv, Israel. The question remains however, which patients would benefit from treatment intensification. 

The randomized controlled CURE-CD trial showed that patients who have high inflammatory activity — a Lewis score ≥ 350 as seen in video capsule endoscopy findings — experienced statistically significantly fewer relapses during the 2-year follow-up vs patients with the same amount of inflammation who continued their standard treatment, he said.

Dr. Ben-Horin presented the results at the annual congress of the European Crohn’s and Colitis Organisation on behalf of the Israeli IBD Research Nucleus. 

He and his colleagues aimed to examine the value of video capsule endoscopy to guide proactive treat-to-target strategy in patients with CD who are in clinical remission, adding onto their previous work published in 2019 that established the benefit of video capsule endoscopy over calprotectin in predicting relapse. 

The prospective randomized controlled trial recruited 60 patients with CD involving the small bowel who were in clinical remission (Crohn’s Disease Activity Index [CDAI] < 150). Patients underwent clinical, biomarker, and imaging checks as well as video capsule endoscopies at baseline and every 6 months thereafter for up to 24 months. 

A total of 40 patients with a Lewis score ≥ 350 and who were considered high-risk were randomized to either proactive treatment optimization (targeting video capsule endoscopy mucosal healing, n = 20) or to continued standard care (n = 20) for 24 months. Patients with a Lewis score < 350 who were considered to be low-risk continued standard care (n = 20) which may or may not have been biologic. 

The primary outcome was the rate of clinical relapse (disease exacerbation comprised of a CDAI increase > 70 points or hospitalization/surgery) by 24 months in high-risk patients who received standard care vs proactive care. 

Secondary outcomes included risk for flare in the low-risk group (all on standard care) vs the high-risk group also on standard care, predictive profiles for flare of calprotectin, MRI, intestinal ultrasound, and Lewis score over the 24 months. 
 

A Nearly Threefold Difference

Treatment intensification in the high-risk proactive strategy group was split between therapeutic drug monitoring–based biologic dose-escalation (n = 11 in 20), starting a biologic (8 in 20), or swapping a biologic (1 in 20). 

By 24 months, clinical flare occurred in 5 in 20 (25%) of the high-risk proactive group vs 14 (70%) of the high-risk standard-care group (odds ratio [OR], 0.14; 95% CI, 0.04-0.57; P = .006), Dr. Ben-Horin reported. 

The data also showed that low-risk patients had a lower incidence of clinical flare at approximately 45% compared with 70% in high-risk patients also on standard care (P = .11 by intention-to-treat analysis; P = .06 by per-protocol analysis).

In an interview, Dr. Ben-Horin said that despite the results, there remained a “big dilemma” about who should be treated if they show mucosal inflammation on video capsule endoscopy. 

“Crohn’s disease is a progressive disease, and we don’t want flares down the road in a patient that currently feels okay but has underlying inflammation,” he said. “On the other hand, it’s important to consider that our therapies are sometimes associated with adverse events, they can be very costly, and become a huge burden to our healthcare systems and to some of the patients.” 

It is important to ask whether we should or treat patients in remission more aggressively “because not everyone will progress and some of them may never flare,” he explained. 

The findings offer three layers of added evidence to the field, Dr. Ben-Horin said. First, it offers further support to the treat-to-target approach if tailored to a high-risk group. Second, the study suggests that treat-to-target studies should be looking only at the high-risk patients and not the entire study population. “This is the first study of its kind to take this approach,” he pointed out. 

“Thirdly, our results build on our preceding trial to show that using video capsule endoscopy enables us to stratify the risk of patients’ with small-bowel Crohn’s disease and tailor their treatment accordingly, probably more accurately than calprotectin or C-reactive protein.”

Asked to comment on the results, Maria Abreu, MD, AGAF, a gastroenterologist who specializes in inflammatory bowel disease at the University of Miami, Miami, Florida, said that though it was a small study, it highlights that patients need to be closely monitored with objective, quantifiable tests for the best outcomes. 

She continued: “Capsule endoscopy is certainly the most sensitive test we have and lends itself in short order to artificial intelligence interpretation and quantification to make it even more robust.”

“We now need to nuance who needs a capsule vs intestinal ultrasound vs a colonoscopy, and that is likely to depend on disease location and manifestations of the disease,” ie, mucosa-only or transmural-predominant disease, she noted. 

Dr. Ben-Horin has declared that the trial was funded by the Helmsley Charitable Trust. The VCE was partly provided by Medtronic. He disclosed advisory board fees and/or consulting and/or research support from Janssen, AbbVie, CellTrion, Takeda, Schering Plough, Pfizer, Ferring, Falk Pharma, GlaxoSmithKline, Novartis, Roche, Galmed, EviNature, Galmed, PredictaMed, NeoPharm. 

Dr. Abreu has served as a consultant and scientific advisory board member for AbbVie, Arena Pharmaceuticals, Bristol-Myers Squibb, Eli Lilly Pharmaceuticals, Gilead, Janssen Biotech, and Prometheus Biosciences, University of California, Berkeley; a speaker for Alimentiv; and has had projects funded by Pfizer, Prometheus Laboratories, and Takeda Pharmaceuticals.

The oral thyroid hormone receptor beta-selective agonist resmetirom (Madrigal Pharmaceuticals) in both 80-mg and 100-mg doses was superior to placebo at achieving resolution of nonalcoholic steatohepatitis (NASH) and improving liver fibrosis, according to the results of the ongoing phase 3 MAESTRO-NASH trial published in The New England Journal of Medicine.

Although certain findings from this trial were initially presented at the European Association for the Study of the Liver Congress 2023, the publication of the full peer-reviewed paper represents a potentially significant milestone in the management of NASH, a disease for which there is currently no approved pharmacologic treatment. 

“Data for the first 1,050 patients from the MAESTRO-NASH trial, together with data from completed resmetirom trials, support the potential for resmetirom to provide benefit to patients with NASH and liver fibrosis,” wrote the authors, led by principal investigator Stephen Harrison, MD, chairman of Pinnacle Clinical Research and Summit Clinical Research in San Antonio, Texas. 

The trial uses the earlier nomenclature of NASH and nonalcoholic fatty liver disease (NAFLD). An international consensus group has since changed these terms to metabolic dysfunction–associated steatohepatitis (MASH) and metabolic dysfunction–associated steatotic liver disease (MASLD), respectively. 
 

A Closer Look at MAESTRO-NASH

Investigators enrolled 996 participants who were randomly assigned to receive placebo or resmetirom at 80 mg or 100 mg. Patients were followed for 52 weeks, at which point, they were assessed for the dual primary endpoints of NASH resolution (including a reduction in the NAFLD activity score by ≥ 2 points) with no worsening of fibrosis and an improvement (reduction) in fibrosis by at least one stage with no worsening of the NAFLD activity score. 

They observed that patients receiving resmetirom had a significant improvement across both doses and both primary endpoints. 

NASH resolution with no worsening of fibrosis was achieved in 25.9% and 29.9% of the patients in the 80-mg and 100-mg groups, respectively, vs 9.7% on placebo. Fibrosis improved by at least one stage with no worsening of the NAFLD activity score in 24.2% and 25.9% of patients in the increasing-dose groups, respectively, compared with 14.2% on placebo (P < .001 for both doses compared with placebo). 

The effects with resmetirom were consistent across key subgroups, regardless of baseline fibrosis stage; baseline NAFLD activity score; or type 2 diabetes status, age, and sex. 

“Multiple non-invasive tests for NASH, steatosis, and fibrosis (including blood biomarkers and imaging) showed a similar direction of effects favoring resmetirom treatment, which supports the findings for the primary end points,” Dr. Harrison and colleagues wrote. 

The majority of patients with NASH also have diabetes. As a result, patients with NASH are known to have a high cardiovascular risk and mortality. However, MAESTRO-NASH investigators reported that compared with those receiving placebo, patients on resmetirom experienced reductions in levels of a broad range of atherogenic lipids and lipoproteins, including low-density lipoprotein (LDL) cholesterol, non–high-density lipoprotein cholesterol, triglycerides, apolipoprotein B, and lipoprotein(a). These findings were consistent with earlier studies of resmetirom. 

From baseline to week 24, LDL cholesterol levels were reduced by -13.6% in the 80-mg and by -16.3% in the 100-mg resmetirom groups compared with 0.1% in the placebo group (P < .001).

More patients in the 100-mg group than in the 80-mg or placebo groups discontinued the trial due to adverse events (6.8% vs 1.8% and 2.2%, respectively). Diarrhea and nausea occurred more frequently in the resmetirom groups than in the placebo group. Serious adverse events occurred with similar incidences across the 100-mg, 80-mg, and placebo groups (12.7%, 10.9%, and 11.5%, respectively).

Although to date the MAESTRO-NASH trial lacks clinical outcomes, over its planned duration of 54 months, investigators will accrue data on liver-related outcomes, including progression to cirrhosis. Likewise, long-term safety data will become available with the trial’s completion.

GLASGOW – An interactive digital decision tool that individualizes menopause care received praise from primary care clinicians in the United Kingdom, who said it could improve patient care and streamline office visits.

The tool, called Wellspring, helps clarify menopause guidelines from the U.K.’s National Institute for Health and Care Excellence while fostering shared decision-making with evidence-based data.  

“Access to hormone replacement therapy [HRT], as well as decision-making around treatment for menopausal symptoms, is often complicated by concerns around its safety, and there is still a knowledge and a confidence gap among health care professionals causing reluctance to prescribe HRT,”  said Aini Kamal, MSc, from University College London. Ms. Kamal presented results of a survey about the tool at the annual meeting of the Royal College of General Practitioners.

For the study, Ms. Kamal, Daniel Reisel, MBBS, PhD, a gynecologist at UCL, and colleagues evaluated Wellspring with doctors, nurses, and pharmacists.

“Ensuring that women receive education around symptoms, so that they are empowered, is a key part of optimizing their care and sharing decision-making,” Dr. Reisel said in an interview. He added that U.K. primary care had seen an increase in cases of women presenting with symptoms associated with the perimenopause and menopause at a time when U.K. Members of Parliament are debating whether to make it mandatory for all women to have menopause check-up in their early 40s.

The online survey was completed by 280 participants, and respondents were primarily GPs with several years of relevant prescribing practice. Of those, 93% found information from national guidelines to be accurately presented in the tool, and 97% said they would recommend this decision aid to other health care professionals, Ms. Kamal reported.

Nearly all participants said they could see themselves using the tool with patients in the clinic or as an adjunct to virtual sessions. “This [finding] was particularly important because it demonstrates the clinical potential this tool has,” she said.

 

One consult, too many problems

Louise Newson, MBChB, who runs the U.K.’s largest menopause clinic, said primary care appointments are often time-pressured and follow a “’one problem-one consultation’” policy. As such, women are often thinking ‘Do I go with my joint pains, or my palpitations, tinnitus, or what?’ If a patient presents with tinnitus, a doctor might focus on the potential of an inner ear problem rather than a hormone deficiency, but I do know that if the woman is perimenopausal or menopausal, we often look to replace the missing hormones, and then if the tinnitus doesn’t improve we can revisit the ear problem.” 

Dr. Newson noted that 17% of women in her clinics have had more than six GP visits in the year before she sees them, but in the year following, this figure drops to 1%. Acknowledging that a menopause consultation for a GP is time-consuming, Dr. Newson pointed out that taking time initially with the patient “means it will reduce the number of future consultations quickly, but more importantly, we also know that taking HRT reduces long-term risk of serious diseases, including heart disease and osteoporosis.”

The digital tool can be used by both doctors and patients to help women work through their symptoms and equip them with knowledge so their GP visits are more productive.

“When we see women who are empowered with knowledge [about menopause symptoms], then the consultations are quicker and essentially place the patient central to the discussion,” Dr. Newson said.

Ed Russell-Smith, MBChB, a GP in Scotland who moderated the session, said the tool “lays out a nicely structured approach and provides modern treatment options and resources for patients.”

However, he added “we also need to remember there are potential harms to be done from HRT too. It’s vitally important that while patients might see HRT as a panacea, doctors need to balance this with the risks involved for each individual. As a tool, I think Wellspring can help us in this respect to apply general principles to that patient and individualize treatment.”

Dr. Reisel, Dr. Newson, Ms. Kamal, and Dr. Russell-Smith disclosed no relevant financial relationships. The Wellspring Decision Aid was supported by UCL’s Institute for Women’s Health. The Newson Health clinic is fully private, but research is done via the nonprofit arm, which is supported by the clinic. There is no pharma involvement.

GLASGOW – An interactive digital decision tool that individualizes menopause care received praise from primary care clinicians in the United Kingdom, who said it could improve patient care and streamline office visits.

The tool, called Wellspring, helps clarify menopause guidelines from the U.K.’s National Institute for Health and Care Excellence while fostering shared decision-making with evidence-based data.  

“Access to hormone replacement therapy [HRT], as well as decision-making around treatment for menopausal symptoms, is often complicated by concerns around its safety, and there is still a knowledge and a confidence gap among health care professionals causing reluctance to prescribe HRT,”  said Aini Kamal, MSc, from University College London. Ms. Kamal presented results of a survey about the tool at the annual meeting of the Royal College of General Practitioners.

For the study, Ms. Kamal, Daniel Reisel, MBBS, PhD, a gynecologist at UCL, and colleagues evaluated Wellspring with doctors, nurses, and pharmacists.

“Ensuring that women receive education around symptoms, so that they are empowered, is a key part of optimizing their care and sharing decision-making,” Dr. Reisel said in an interview. He added that U.K. primary care had seen an increase in cases of women presenting with symptoms associated with the perimenopause and menopause at a time when U.K. Members of Parliament are debating whether to make it mandatory for all women to have menopause check-up in their early 40s.

The online survey was completed by 280 participants, and respondents were primarily GPs with several years of relevant prescribing practice. Of those, 93% found information from national guidelines to be accurately presented in the tool, and 97% said they would recommend this decision aid to other health care professionals, Ms. Kamal reported.

Nearly all participants said they could see themselves using the tool with patients in the clinic or as an adjunct to virtual sessions. “This [finding] was particularly important because it demonstrates the clinical potential this tool has,” she said.

COPENHAGEN – People with precancerous colonic lesions show significant differences in their gut microbiome, compared with the general population up to 5 years before the lesions develop, according to a large, 22-year analysis from the Dutch Microbiome Project cohort study.

The findings suggest a possible role for gut microbiota in the development of colorectal lesions and cancer, said study lead Ranko Gacesa, PhD, from the department of gastroenterology, University of Groningen (the Netherlands), who presented the results at the annual United European Gastroenterology Week.

“It [also] suggests that gut bacteria might enhance currently used noninvasive fecal tests for the detection of colorectal polyps, and even that microbiome-modulating therapies might play a role in prevention of colorectal cancer,” said Dr. Gacesa, who won the award for best abstract in the meeting session.

The gut microbiome is known to be linked to colorectal cancer (CRC); in particular, the bacteria Bacteroides fragilis and Alistipes finegoldii have been found to cause CRC in mouse models, explained Dr. Gacesa.

In the current study, Dr. Gacesa and colleagues looked at the potential for the gut microbiome in humans to play a role in the detection of precancerous colonic lesions. The noninvasive fecal immunochemical test (FIT), recently shown to be a preference among patients, produces a high number of false-positive results, leading to many unnecessary colonoscopies.

“It has been calculated that the use of a fecal microbiota analysis combined with FIT in the early-stage prediction of CRC could result in a high true-positive rate and a low false-positive rate,” said Dr. Gacesa. “In this way, we might reduce the false-positive rate by around 50%. 

“Ideally, we don’t want to detect cancer when it is already established and is hard to treat. We want to detect it as early in its development as possible,” he said.
 

Longitudinal analysis using large Dutch databases

To determine the direction of the relationship between CRC and the gut microbiome, the Dutch researchers conducted a longitudinal analysis from 2000 to 2022, looking at whether CRC alters the gut microbiome, as well as whether changes in the microbiome contribute to the development of precancerous lesions and CRC.

They drew on data from the Dutch colorectal cancer screening program, comprising FIT results in people aged 55 years and older, and colonoscopy if referred. They recorded cases of colonic biopsies from the extensive Dutch national database of medical biopsies. These were then linked with Dutch microbiome project data sourced from fecal samples of 8208 individuals taken between 2012 and 2015.

“This allowed us to associate gut microbiome compositions and functions to detailed histological information about precancerous lesions and CRC, including when lesions were detected relative to fecal sampling [and a reading of the gut microbiome],” Dr. Gacesa explained. 

The analysis determined the composition, function, and genomic profiles of gut microbiota in participants who developed precancerous colorectal lesions before fecal sampling from 2000 to 2015, and in those participants who developed lesions after fecal sampling, between 2015 and 2022. Clinical phenotypes, comprising the type and size of lesions, were noted. The control group included 2123 individuals from the general population with normal colonoscopy findings.
 

More precancerous lesions found after fecal sampling

There were more cases of precancerous lesions found after fecal sampling, reported Dr. Gacesa.

Before fecal sampling, 219 participants had colonic lesions, including low-grade dysplasia, high-grade dysplasia, and serrated polyps, and 26 cases of CRC. A total of 315 participants developed assorted colonic lesions after fecal sampling, with a total of 29 cases of CRC.

When the researchers looked at microbiome diversity in people who had experienced precancerous colonic lesions 1-5 years before fecal sampling, they found that diversity was lower, compared with controls. Microbiome diversity was also decreased in participants who developed colonic lesions after sampling.

The microbiome composition and function were different between patients with preexisting and future lesions, and varied based on the types of lesion.

“We saw a drop in some commensal bacteria, including Faecalibacterium, in both those with recent pathologies and those who developed them in the future. We also saw a massive spike in Alistipes finegoldii in those who had CRC, strongly suggesting it is closely linked to CRC in people,” reported Dr. Gacesa.

Among bacterial species linked with the future development of precancerous lesions were those from the family of Lachnospiraceae, and the genera Roseburia and Eubacterium. Microbiome composition had a moderate predictive power for future lesions and CRC.

“Precancerous lesions are linked to the gut microbiome,” Dr. Gacesa said. “Adenomas – both preexisting ones (before fecal sampling), and ones that came after fecal sampling – are significantly linked to the microbiome composition.”
 

More time needed

Loris Lopetuso, MD, gastroenterologist, from Fondazione Policlinico Universitario Agostino Gemelli, Rome, who comoderated the session, remarked that the data were intriguing and important.

“We really need to find new predictors of tumorigenesis,” he said. “We already have some good predictors, mainly FIT, but these are not enough. These gut microbiota look promising.”

He added that the study by Dr. Gacesa’s team was one of the largest he had seen. “But I would note that, methodologically, we need to remember that the time between a fecal sample and the development of polyps can be very large,” Dr. Lopetuso emphasized. “This study looked at around 5 years only. Also, the microbiota can change from one day to the other in response to stress, diet, and many other things.” 

However, “this could be the beginning of a longitudinal study between cases and controls because many years are needed,” he added.

Dr. Gacesa has received funding from Janssen Pharmaceuticals for an unrelated research project. He is a paid R&D consultant for Esox Biologics Ltd for topics unrelated to this project. Dr. Lopetuso reported no relevant financial relationships.

GLASGOW – Three-quarters of women going through perimenopause and menopause experience unexpected distressing, debilitating, and embarrassing symptoms but often fail to receive appropriate treatment, a large U.K.-based survey found. 

“For too long, many people have thought of menopause as just hot flashes and vaginal dryness. But we know hormones work all over our body, so there are many symptoms beyond that,” said Daniel Reisel, MBBS, PhD, a gynecologist at University College London, who presented the survey findings at the 2023 annual meeting of the Royal College of General Practitioners.

Primary care physicians in the United Kingdom have seen an increase in cases of women presenting with symptoms associated with menopause at a time when the country’s Parliament is debating whether all women should have a menopause check-up in their early 40s, he said.  

Still, only around 14% of menopausal women in the United Kingdom are prescribed hormone replacement therapy (HRT), despite national and international guidelines clearly stating the benefits of the treatment generally outweigh the risks.

Louise Newson, MBChB, who runs the U.K.’s largest menopause clinic, said many women with symptoms of menopause feel the medical system “gaslights” them – dismissing their concerns as trivial or even fabricated.

In her clinic, she typically sees many women with poor sleep, as well as muscle and joint pains. “Yet [when they visit their GPs], they are incorrectly told that it can’t be hormones because they’re still having periods,” she said.
 

Prescribed antidepressants often precede HRT

The new study sought to learn what women knew and experienced with respect to menopause symptoms and what they thought was important.

Of the 5,744 women who responded to the survey, 79.4% were aged 40-60 years and 84.6% were White. “The survey respondents were not different from the distribution of ethnicities we see in NHS menopause care,” said Dr. Reisel, adding that “the barriers are greater for women in poorer areas and for those who are non-White.”

A total of 30.4% had two to five hospital consultations before the health care professional considered that symptoms were related to changing hormone levels; 38.5% were offered antidepressants before HRT. Nearly all (94.6%) said they had experienced negative mood changes and emotions since becoming perimenopausal or menopausal; of these, 19.1% were formally diagnosed with depression or a mood disorder.

“This all just highlights the frustrations I feel around menopause care,” Dr. Newson said. “Women are often not given the tools to properly understand what’s going on and then they don’t ask for the right treatment, and many are given antidepressants. It’s still medicalizing the menopause but in a different way.”
 

Education gap

The researchers also asked women if they had experienced any surprising or unexpected symptoms since becoming perimenopausal or menopausal. To this question, 74.2% said they had. Joint pain was the most common unexpected issue (34%), followed by dry eyes (26%), heart palpitations (25%), and hair issues such as dryness, thinning, and loss (20%).

Dr. Reisel said words used to describe these symptoms in free text responses included “distressing,” “debilitating,” “depressing,” and “embarrassing.”

“When an early-50s woman comes to the GP with dry eyes, joint pain, or recurrent urinary tract infections, for example, before prescribing ibuprofen, or antibiotics, GPs should consider replacing a woman’s hormones and then see what is left in terms of symptoms,” he said.

Cognitive problems and negative mood changes also are common and often overlooked, Dr. Reisel noted. “We often see striking improvements in mood and cognition in women who are prescribed testosterone for low libido, yet symptoms in these areas are not currently an indication to start treatment,” he said. “Data from Newson Health show that 18% have suicidal thoughts in the past 2 weeks, and not many people think about this.”

Much of this lack of understanding around unexpected symptoms relates to a lack of awareness and education. “It goes back to primary and secondary school, and more broadly, these issues are not often talked about in society,” he said.  

Dr. Reisel also noted that language and cultural barriers often stand in the way. “Many cultures don’t discuss menopause and hormone health in general at all. For example, in Bengali, spoken by 300 million people, there is no word in for menopause. So many women are gaslighted when they try and describe their symptoms, or they’re simply just unaware.”

Dr. Reisel and Dr. Newson reported no relevant financial relationships.

A total of 30.4% had two to five hospital consultations before the health care professional considered that symptoms were related to changing hormone levels; 38.5% were offered antidepressants before HRT. Nearly all (94.6%) said they had experienced negative mood changes and emotions since becoming perimenopausal or menopausal; of these, 19.1% were formally diagnosed with depression or a mood disorder.

“This all just highlights the frustrations I feel around menopause care,” Dr. Newson said. “Women are often not given the tools to properly understand what’s going on and then they don’t ask for the right treatment, and many are given antidepressants. It’s still medicalizing the menopause but in a different way.”
 

Education gap

The researchers also asked women if they had experienced any surprising or unexpected symptoms since becoming perimenopausal or menopausal. To this question, 74.2% said they had. Joint pain was the most common unexpected issue (34%), followed by dry eyes (26%), heart palpitations (25%), and hair issues such as dryness, thinning, and loss (20%).

Dr. Reisel said words used to describe these symptoms in free text responses included “distressing,” “debilitating,” “depressing,” and “embarrassing.”

“When an early-50s woman comes to the GP with dry eyes, joint pain, or recurrent urinary tract infections, for example, before prescribing ibuprofen, or antibiotics, GPs should consider replacing a woman’s hormones and then see what is left in terms of symptoms,” he said.

Cognitive problems and negative mood changes also are common and often overlooked, Dr. Reisel noted. “We often see striking improvements in mood and cognition in women who are prescribed testosterone for low libido, yet symptoms in these areas are not currently an indication to start treatment,” he said. “Data from Newson Health show that 18% have suicidal thoughts in the past 2 weeks, and not many people think about this.”

Much of this lack of understanding around unexpected symptoms relates to a lack of awareness and education. “It goes back to primary and secondary school, and more broadly, these issues are not often talked about in society,” he said.  

Dr. Reisel also noted that language and cultural barriers often stand in the way. “Many cultures don’t discuss menopause and hormone health in general at all. For example, in Bengali, spoken by 300 million people, there is no word in for menopause. So many women are gaslighted when they try and describe their symptoms, or they’re simply just unaware.”

GLASGOW – Three-quarters of women going through perimenopause and menopause experience unexpected distressing, debilitating, and embarrassing symptoms but often fail to receive appropriate treatment, a large U.K.-based survey found. 

“For too long, many people have thought of menopause as just hot flashes and vaginal dryness. But we know hormones work all over our body, so there are many symptoms beyond that,” said Daniel Reisel, MBBS, PhD, a gynecologist at University College London, who presented the survey findings at the 2023 annual meeting of the Royal College of General Practitioners.

Primary care physicians in the United Kingdom have seen an increase in cases of women presenting with symptoms associated with menopause at a time when the country’s Parliament is debating whether all women should have a menopause check-up in their early 40s, he said.  

Still, only around 14% of menopausal women in the United Kingdom are prescribed hormone replacement therapy (HRT), despite national and international guidelines clearly stating the benefits of the treatment generally outweigh the risks.

Louise Newson, MBChB, who runs the U.K.’s largest menopause clinic, said many women with symptoms of menopause feel the medical system “gaslights” them – dismissing their concerns as trivial or even fabricated.

In her clinic, she typically sees many women with poor sleep, as well as muscle and joint pains. “Yet [when they visit their GPs], they are incorrectly told that it can’t be hormones because they’re still having periods,” she said.
 

Prescribed antidepressants often precede HRT

The new study sought to learn what women knew and experienced with respect to menopause symptoms and what they thought was important.

Of the 5,744 women who responded to the survey, 79.4% were aged 40-60 years and 84.6% were White. “The survey respondents were not different from the distribution of ethnicities we see in NHS menopause care,” said Dr. Reisel, adding that “the barriers are greater for women in poorer areas and for those who are non-White.”

HAMBURG, Germany – Use of some antibiotic and antipsychotic drugs increases the risk of sudden cardiac arrest (SCA) among people with type 2 diabetes who do not have a history of cardiovascular disease (CVD), shows the first such analysis of real-world, primary care data.

People with type 2 diabetes who do not have a history of CVD have almost three times the risk of SCA if they take antipsychotic medications and nearly double the risk if they take certain antibiotics that prolong the QT interval, notably, macrolides and fluoroquinolones.

“These data show that commonly prescribed drugs - antipsychotic medications, used by about 3% of people with type 2 diabetes, and antibiotics, taken by 5% to 10%, convey an increased risk of sudden cardiac arrest in those without a history of cardiovascular disease,” said Peter Harms, MSc, who presented the study at the annual meeting of the European Association for the Study of Diabetes. Another drug associated with an increase in SCA among patients with diabetes was domperidone, an antinausea medication.

“Perhaps these drugs could be avoided in some cases, and GPs should be more aware of the possible consequences of their use,” he added. “If the patient has type 2 diabetes, then maybe it’s better to avoid some of these medications and try and cope without them, or at least find an alternative antibiotic.”

Mr. Harms, an epidemiologist from Amsterdam University Medical Centers, highlighted that their study was unique because the investigators drew upon primary care data. “These data are extensive, and we find a lot of associations which are very real.”

SCA is associated with 50% of all cardiac deaths and accounts for 20% of all mortality in high-income countries. Of those people who experience SCA, 80% of cases prove fatal.

“As the name suggests, it is difficult to predict because it is sudden, especially in people without a cardiovascular disease history,” Mr. Harms pointed out in an interview with this news organization. He highlighted that “around half of those who experience SCA, often between the ages of 40 and 60 years, have never seen a cardiologist, but many do have type 2 diabetes.

“We need to better understand how to recognize people at risk of SCA, know who to watch and how to prevent these events,” he emphasized.

Vladimira Fejfarova, MD, comoderated the session and commented on the study. “From the clinical point of view, it’s necessary to evaluate risk factors that can contribute to sudden cardiac arrest.”

Overall, the researchers found that, among people with type 2 diabetes who do not have a history of CVD, hypoglycemia, severe hypertension, dyslipidemia, and use of QTc-prolonging medications are associated with SCA risk. Among people with type 2 diabetes and CVD, albuminuria and heart failure are associated with SCA risk.

Dr. Fejfarova added: “With type 2 diabetes and also type 1, we need to look more at adverse events, especially when treating infections with macrolides, but also mycotic infections, because antimycotic drugs are known to influence QT intervals that could contribute to sudden cardiac arrest.

“We need to be more cautious with prescribing certain antibiotics that have these side effects in our patients with diabetes,” asserted Dr. Fejfarova, from the Diabetes Centre, Institute for Clinical and Experimental Medicine, Prague.
 

Type 2 diabetes doubles the risk of SCA

The researcher decided to investigate the population of people with type 2 diabetes because their risk of SCD is around twice that of those without type 2 diabetes. Because these patients have relatively frequent checkups with general practitioners, Mr. Harms turned to primary care databases that contained comprehensive and relatively routine information on risk indicators.

Longitudinal associations between clinical characteristics of 3,919 patients with type 2 diabetes – both those with and those without a history of CVD – and SCA (a total of 689 patients) were determined.

Cases were found in the AmsteRdam REsuscitation STtudies (ARREST) registry of out-of-hospital resuscitation attempts by emergency medical services in the Dutch region of Noord-Holland from 2010 to 2019. Case patients were matched with up to five control patients. The control group comprised people with type 2 diabetes who had not experienced an SCA. Control patients were sourced from the same primary care practices who were of similar age and sex. Clinical measurements, including blood pressure and blood glucose readings, medication use, and medical history for the 5 years leading up to an SCA, were obtained from general practice records. A multivariable analysis was performed, and results were stratified for people with and for those without a history of CVD.

Of particular interest were drugs that interfere with cardiac function, including some prokinetic, antibiotic, and antipsychotic medications. All of the drugs are known to be associated with a change in QTc prolongation. Examples include domperidone (QTc-prolonging prokinetic), macrolides and fluoroquinolones (QTc-prolonging antibiotics), and haloperidol (a QTc-prolonging antipsychotic).
 

Antibiotic and antipsychotic use might contribute to SCA in T2D

Case patients and control patients were similar in age, hemoglobin A1c level, and other characteristics with the exception that more patients with SCA had a history of CVD (40.0% vs. 29.4%).

“Looking at the associations in the overall population, insulin use was strongly associated with SCA risk [hazard ratio, 2.38] and perhaps this was an indicator of severity of type 2 diabetes,” remarked Mr. Harms. “Also, unsurprisingly, a history of arrhythmia [HR, 1.68] and, more surprisingly, prokinetic drug use [HR, 1.66; 95% confidence interval, 1.20-2.31], specifically those known for QTc-prolongation, were associated with SCA.”

Among people who had experienced an SCA and who did not have a history of CVD (337 case patients/2,023 control patients), QTc-prolonging antipsychotic medication use was associated with SCA at an HR of 2.87, and antibiotic medication use was associated with SCA at an HR of 1.66. A low fasting glucose level (< 4.5 mmol/mol) was associated with SCA at an HR of 2.5; severely high systolic blood pressure (> 180 mm Hg) was associated with SCA at an HR of 2.21; low HDL cholesterol level, with an HR of 1.35; and high LDL cholesterol level (> 2.6 mmol/L), with an HR of 1.64.

Among people with a history of CVD (352 case patients/1,207 control patients), associations between albuminuria and SCA were moderate (HR, 1.54) and severe (HR, 1.55); heart failure was associated with SCA at an HR of 1.85 (95% CI, 1.50-2.29).

Comoderator Dr. Fejfarova added that, in addition to the findings from Dr. Harms’ study, other research presented in the same session highlighted the importance of checking patients for the presence of arrhythmias that could lead to the development of atrioventricular blocks, sinus node diseases, and SCA.

GLASGOW – ChatGPT failed to pass the U.K.’s National Primary Care examinations in a new study, highlighting how artificial intelligence (AI) does not necessarily match human perceptions of medical complexity.

ChatGPT also provided novel explanations – it frequently “hallucinates” – by describing inaccurate information as if they were facts, according to Shathar Mahmood, BA, a fifth-year medical student at the University of Cambridge, England, who presented the findings at the annual meeting of the Royal College of General Practitioners. The study was published in JMIR Medical Education earlier this year.

“Artificial intelligence has generated impressive results across medicine, and with the release of ChatGPT there is now discussion about these large language models taking over clinicians’ jobs,” Arun James Thirunavukarasu, MB BChir, of the University of Oxford, England, and Oxford University Hospitals NHS Foundation Trust, who is the lead author of the study, told this news organization.

Performance of AI on medical school examinations has prompted much of this discussion, often because performance does not reflect real-world clinical practice, he said. “We used the Applied Knowledge Test instead, and this allowed us to explore the potential and pitfalls of deploying large language models in primary care and to explore what further development of medical large language model applications is required.”

The researchers investigated the strengths and weaknesses of ChatGPT in primary care using the Membership of the Royal College of General Practitioners Applied Knowledge Test. The computer-based, multiple-choice assessment is part of the U.K.’s specialty training to become a general practitioner (GP). It tests knowledge behind general practice within the context of the United Kingdom’s National Health Service.

The researchers entered a series of 674 questions into ChatGPT on two occasions, or “runs.” “By putting the questions into two separate dialogues, we hoped to avoid the influence of one dialogue on the other,” Ms. Mahmood said. To validate that the answers were correct, the ChatGPT responses were compared with the answers provided by the GP self-test and past articles.
 

Docs 1, AI 0

Overall performance of the algorithm was good across both runs (59.94% and 60.39%); 83.23% of questions produced the same answer on both runs.

But 17% of the answers didn’t match, Ms. Mahmood reported, a statistically significant difference. “And the overall performance of ChatGPT was 10% lower than the average RCGP pass mark in the last few years, which informs one of our conclusions about it not being very precise at expert level recall and decision-making,” she said.

Also, a small percentage of questions (1.48% and 2.25% in each run) produced an uncertain answer or there was no answer.
 

Say what?

Novel explanations were generated upon running a question through ChatGPT that then provided an extended answer, Ms. Mahmood said. When the accuracy of the extended answers was checked against the correct answers, no correlation was found. “ChatGPT can hallucinate answers, and there’s no way a nonexpert reading this could know it is incorrect,” she said.

Regarding the application of ChatGPT and similar algorithms to clinical practice, Ms. Mahmood was clear. “As they stand, [AI systems] will not be able to replace the health care professional workforce, in primary care at least,” she said. “I think larger and more medically specific datasets are required to improve their outputs in this field.”

Sandip Pramanik, MBcHB, a GP in Watford, Hertfordshire, England, said the study “clearly showed ChatGPT’s struggle to deal with the complexity of the exam questions that is based on the primary care system. In essence, this in indicative of the human factors involved in decision-making in primary care.”

The applied knowledge test is designed to test the knowledge required to be a generalist in the primary care setting, and as such, there are lots of nuances reflecting this within the questions, Dr. Pramanik said.

“ChatGPT may look at these in a more black and white way, whereas the generalist needs to be reflective of the complexities involved and the different possibilities that can present rather than take a binary ‘yes’ or ‘no’ stance,” he said. “In fact, this highlights a lot about the nature of general practice in managing uncertainty, and this is reflected in the questions asked in the exam,” he remarked. He noted, “Being a generalist is about factoring in human emotion and human perception as well as knowledge.”

Ms. Mahmood, Dr. Thirunavukarasu, and Dr. Pramanik have disclosed no relevant financial relationships.

It tests knowledge behind general practice within the context of the United Kingdom’s National Health Service.

The researchers entered a series of 674 questions into ChatGPT on two occasions, or “runs.” “By putting the questions into two separate dialogues, we hoped to avoid the influence of one dialogue on the other,” Ms. Mahmood said. To validate that the answers were correct, the ChatGPT responses were compared with the answers provided by the GP self-test and past articles.

Overall performance of the algorithm was good across both runs (59.94% and 60.39%); 83.23% of questions produced the same answer on both runs.

But 17% of the answers didn’t match, Ms. Mahmood reported, a statistically significant difference. “And the overall performance of ChatGPT was 10% lower than the average RCGP pass mark in the last few years, which informs one of our conclusions about it not being very precise at expert level recall and decision-making,” she said.

Also, a small percentage of questions (1.48% and 2.25% in each run) produced an uncertain answer or there was no answer.
 

Say what?

Novel explanations were generated upon running a question through ChatGPT that then provided an extended answer, Ms. Mahmood said. When the accuracy of the extended answers was checked against the correct answers, no correlation was found. “ChatGPT can hallucinate answers, and there’s no way a nonexpert reading this could know it is incorrect,” she said.

Regarding the application of ChatGPT and similar algorithms to clinical practice, Ms. Mahmood was clear. “As they stand, [AI systems] will not be able to replace the health care professional workforce, in primary care at least,” she said. “I think larger and more medically specific datasets are required to improve their outputs in this field.”

Sandip Pramanik, MBcHB, a GP in Watford, Hertfordshire, England, said the study “clearly showed ChatGPT’s struggle to deal with the complexity of the exam questions that is based on the primary care system. In essence, this in indicative of the human factors involved in decision-making in primary care.”

The applied knowledge test is designed to test the knowledge required to be a generalist in the primary care setting, and as such, there are lots of nuances reflecting this within the questions, Dr. Pramanik said.

“ChatGPT may look at these in a more black and white way, whereas the generalist needs to be reflective of the complexities involved and the different possibilities that can present rather than take a binary ‘yes’ or ‘no’ stance,” he said. “In fact, this highlights a lot about the nature of general practice in managing uncertainty, and this is reflected in the questions asked in the exam,” he remarked. He noted, “Being a generalist is about factoring in human emotion and human perception as well as knowledge.”

GLASGOW – ChatGPT failed to pass the U.K.’s National Primary Care examinations in a new study, highlighting how artificial intelligence (AI) does not necessarily match human perceptions of medical complexity.

ChatGPT also provided novel explanations – it frequently “hallucinates” – by describing inaccurate information as if they were facts, according to Shathar Mahmood, BA, a fifth-year medical student at the University of Cambridge, England, who presented the findings at the annual meeting of the Royal College of General Practitioners. The study was published in JMIR Medical Education earlier this year.

“Artificial intelligence has generated impressive results across medicine, and with the release of ChatGPT there is now discussion about these large language models taking over clinicians’ jobs,” Arun James Thirunavukarasu, MB BChir, of the University of Oxford, England, and Oxford University Hospitals NHS Foundation Trust, who is the lead author of the study, told this news organization.

Performance of AI on medical school examinations has prompted much of this discussion, often because performance does not reflect real-world clinical practice, he said. “We used the Applied Knowledge Test instead, and this allowed us to explore the potential and pitfalls of deploying large language models in primary care and to explore what further development of medical large language model applications is required.”

GLASGOW – Amitriptyline, titrated at low dose, was superior to placebo as a second-line treatment for irritable bowel syndrome (IBS) across multiple outcomes in what the researchers call the largest randomized controlled trial (RCT) of a tricyclic antidepressant in the condition.

Patients who took low-dose amitriptyline were almost twice as likely to report an overall improvement in symptoms as those taking placebo, according to investigators of the Amitriptyline at Low-Dose and Titrated for Irritable Bowel Syndrome as Second-Line Treatment (ATLANTIS) trial. Low-dose amitriptyline appeared safe and well tolerated, they reported.

Hazel Everitt, PhD, professor of primary care research at the University of Southampton, England, presented the findings at the annual conference of the Royal College of General Practitioners.

The data were also published in The Lancet and were presented at the recent United European Gastroenterology Week 2023.

Clinicians “should offer low-dose amitriptyline to patients with IBS whose symptoms do not improve with first-line therapies, with appropriate support to guide patient-led dose titration,” the researchers wrote in the journal article.

Despite first-line treatments such as diet, fiber, and antispasmodics, many patients with IBS continue to have troublesome symptoms, Dr. Everitt said in an interview. “GPs haven’t often prescribed amitriptyline for IBS – probably because of the lack of research evidence for its use in primary care.”

Dr. Everitt added that primary care physicians and patients interviewed for the study welcomed low-dose amitriptyline as a potential additional option, especially with increased patient-led care. “The dose titration document that was developed with patients specifically for the trial enables patients to be more empowered to manage their IBS by helping them to titrate their dose up or down depending on their symptoms and side effects.”

Judith Danby, MBBS, a retired GP who moderated the session at which the ATLANTIS results were presented, said, “Self-titration of the dose equals patient empowerment, and if patients can be helped to manage their own medication, then they will also be more empowered to think about lifestyle change, too.”
 

RCT across 55 practices

The U.K.’s National Institute for Health and Care Excellence guidance for the management of IBS in primary care says clinicians should “consider” using low-dose tricyclic antidepressants as a second-line treatment but highlight the need for an RCT of these drugs carried out solely in primary care.

The ATLANTIS trial was conducted across 55 general practices in England and included adults with Rome IV IBS of any subtype and ongoing symptoms (IBS Severity Scoring System [IBS-SSS] score ≥ 75 points) despite dietary changes and first-line therapies. Participants had normal full blood counts and C-reactive protein measures, negative celiac serology, and no evidence of suicidal ideation. The mean age was 48.5 years, and 68% were female. The mean IBS-SSS score in all participants was 272.8 at baseline.

Patients were randomly assigned in a 1:1 ratio to receive either low-dose oral amitriptyline (10 mg once daily; n = 232) with dose titration over 3 weeks (up to a maximum dose of 30 mg once daily) as determined by a participant’s symptoms and tolerability; or placebo (n = 231). Both groups participated for 6 months. The primary outcome was the IBS-SSS score at 6 months.
 

Amitriptyline

Three-quarters of participants adhered to the therapy over the 6 months, which was particularly notable given that the trial was conducted during the COVID-19 pandemic, according to the researchers.

An intent-to-treat analysis found that at 6 months, amitriptyline was superior to placebo, with a significant mean difference in IBS-SSS score between groups of –27.0 (95% confidence interval, –46.9 to –7.1; P = .0079; mean IBS-SSS, 170.4 vs. 200.1 with amitriptyline and placebo). A secondary outcome showed an increased likelihood of relief of IBS symptoms by subjective global assessment (odds ratio, 1.78; 95% CI. 1.19-2.66; P = .0050).

At 3 months, the difference in mean change in IBS-SSS score between groups was also significant, at –23.3 (95% CI, –42.0 to –4.6; P = .014), the researchers reported.

People who took the drug were 70% more likely to report relief of symptoms on SGA than those who took placebo (P = .08), according to the researchers.

The researchers reported no effect of low-dose amitriptyline on psychiatric symptoms, such as distressing thoughts, anxiety, and depression, during the 6-month follow-up, nor was there any effect on ability to work or go about social activities.

“This was a pragmatic trial performed in a large number of participants with IBS, with an average duration of symptoms of 10 years and with 80% having moderate to severe symptoms at baseline,” Alexander Ford, MD, professor of gastroenterology at the University of Leeds, England, and a coinvestigator on the study, told this news organization. “The fact that amitriptyline showed such a strong effect over placebo in this group of patients, with a mean decrease in IBS-SSS of almost 100 points at both 3 and 6 months, is therefore all the more impressive.”

Mild adverse events, such as dry mouth and drowsiness, were more frequent with low-dose amitriptyline than with placebo,

Dr. Everitt said the ATLANTIS findings could change practice. Previous trials of low-dose amitriptyline for IBS had mostly been small and were conducted in secondary care settings such as gastroenterology clinics with relatively short follow-up times.

“This is a problem for a long-term condition that fluctuates over time and is diagnosed and managed mostly in primary care,” she said. “The ATLANTIS trial is the largest trial of low-dose amitriptyline for IBS undertaken worldwide and was rigorously conducted with 6 months follow-up, providing reliable results that can help inform GPs and patients’ treatment decision-making in usual clinical practice.”

On a pragmatic level, the research group developed a dose titration document for use by patients and GPs. “Both the GPs and participants found the ATLANTIS dose titration document acceptable and helpful,” Dr. Everitt pointed out. She noted, “We’ve made the dose titration document freely available to support patients and clinicians to try low-dose amitriptyline for IBS.”

COPENHAGEN – A real-time, blood-sensing capsule that detects upper gastrointestinal bleeding (UGIB) is safe and effective for patients before undergoing upper endoscopy, according to results from the first U.S.-based open-label, single-arm comparative clinical trial of a novel bleeding sensor for patients with suspected UGIB. It is also the largest such trial.

The capsule (PillSense, EnteraSense) is rapidly deployed, safe to use, and easy to interpret, study researchers say. In under 7 minutes, it correctly detected the presence of blood in 26 of 28 patients and its absence in 87 of 96 patients, as confirmed afterward by esophagogastroduodenoscopy (EGD).

“The use of the PillSense system will positively impact patient outcomes by providing early diagnosis, triaging, and directing care for UGIB,” said Karl Akiki, MD, study lead, who is in the division of gastroenterology and hepatology at the Mayo Clinic, Rochester, Minn. He presented the results at the annual United European Gastroenterology Week.

“Due to its ability to rapidly diagnose UGIB, it helps us, as doctors, expedite accurate clinical decision-making while also optimizing services to ensure the maximum number of patients obtain the best outcome,” he told this news organization.

“There are some pre-endoscopic assessment scores, like the Rockell or the Glasgow-Blatchford score, but they have limited clinical utility in predicting and confirming bleeding in suspected patients,” explained Dr. Akiki. He highlighted the need for a novel device that is rapid, accurate, and safe to use. He also pointed out that despite being the gold standard for diagnosis, EGD remains challenging in terms of time, personnel, and resources.

“The results of our study show the PillSense is a good diagnostic tool that will aid triage,” he said. He noted that PillSense and EGD supplement each other in patient care.

It’s not a device to replace the EGD itself,” he explained, but given the results from the capsule, it will act “as a kind of a bridge that helps us to determine which patients should undergo EGD.”

Optical sensing technology

The researchers aimed to assess the safety and efficacy of the PillSense system for patients with suspected UGIB. They enrolled 131 patients (mean age, 62 years), 60% of whom were men. The most common presenting symptoms for UGIB were melena (52%), anemia (41%), and hematemesis (15%). Five participants withdrew consent before capsule ingestion, and for two patients, primary endpoint data were missing. This left an intent-to-treat population of 124 patients; 110 completed the study.

Patients were asked to swallow the capsule and to lay on their left side. The PillSense is based on optical sensing technology that uses an optical signature of blood in the gut. The device differentiates blood from any other liquids that may be present. After 5-7 minutes, the device gathers and transmits data wirelessly to an external, handheld receiver that processes binary data and indicates either “blood detected” or “no blood detected” in the upper GI tract, explained Dr. Akiki.

Following the capsule reading, patients underwent EGD within 4 hours. This enabled the researchers to compare data between the two modalities. Follow-up visits were conducted on days 7, 14, and 21 to ensure the capsule had passed from the body. Endoscopists were blinded to the capsule result when reading the EGD.

Primary endpoints were the sensitivity and specificity of the device; secondary endpoints were positive predictive value, negative predictive value, successful passage of the capsule, and safety.
 

Rapid and accurate

The researchers determined the efficiency of the capsule in correctly detecting a UGIB. The capsule’s positive and negative predictive values were 74.3% and 97.8%, respectively.

“We achieved a sensitivity of around 93% (92.9%; P = 0.024) with the PillSense capsule and a specificity of 91% (90.6%; P < .001]), which were pretty good. We also detected a range from minimal bleeding – so, speckles of blood to large amounts of active bleeding covering the entire stomach,” reported Dr. Akiki.

There were no differences in terms of patient demographics, laboratory results, or concomitant use of medications. PillSense recording time was a mean of 6.71 minutes, the time from capsule ingestion to EGD was a mean of 55 minutes, and the time to capsule passage through the GI tract was 3.6 days. Most bleeds were found to be in the stomach (18/30; 60%), followed by the duodenum (5/30; 16.6%).

Various capsules for detecting UGIB are under development or are already available, but unlike some of the others, “[the PillSense] is not a video capsule,” said Dr. Akiki. “It does not take pictures at all but is more of a photo sensor capsule that measures the absorption of wavelengths.”

This explains why the PillSense was so rapid – results were available in around 7 minutes and did not require an interpretation by a physician, he explained. “Trained non-physician personnel can use it, and this is where it differs from other devices, such as video capsules that require someone highly trained to interpret the output. It’s an easy procedure and process to follow.”

The PillSense has value in improving workflow, Dr. Akiki said. “If we had someone come in during the night with a suspected upper GI bleed, we could give them the capsule, determine if they need an EGD or not, and potentially postpone it to a time – say, the morning, when more resources are available – freeing up the night for emergency cases. It helps me, as a physician, to determine which patients to send to EGD immediately or which to wait.”

He added that more studies are needed in the postmarketing phase to understand optimal use of the device and to define the exact clinical pathway for optimal implementation.

The device was approved by the U.S. Food and Drug Administration in February. Dr. Akiki noted that there were no adverse events or deaths related to the capsule.

Co-moderator, Philip Chiu, MD, a gastroenterologist from the Chinese University of Hong Kong, said, “It’s an interesting study, because sometimes we can’t differentiate by clinical symptoms as to whether this is a problem of continuous bleeding or something else. The capsule might help us in our decision-making in this respect and help determine whether we should scope the patients or just manage conservatively.”

Dr. Akiki and Dr. Chiu have disclosed no relevant financial relationships.

“There are some pre-endoscopic assessment scores, like the Rockell or the Glasgow-Blatchford score, but they have limited clinical utility in predicting and confirming bleeding in suspected patients,” explained Dr. Akiki. He highlighted the need for a novel device that is rapid, accurate, and safe to use. He also pointed out that despite being the gold standard for diagnosis, EGD remains challenging in terms of time, personnel, and resources.

“The results of our study show the PillSense is a good diagnostic tool that will aid triage,” he said. He noted that PillSense and EGD supplement each other in patient care.

It’s not a device to replace the EGD itself,” he explained, but given the results from the capsule, it will act “as a kind of a bridge that helps us to determine which patients should undergo EGD.”

Optical sensing technology

The researchers aimed to assess the safety and efficacy of the PillSense system for patients with suspected UGIB. They enrolled 131 patients (mean age, 62 years), 60% of whom were men. The most common presenting symptoms for UGIB were melena (52%), anemia (41%), and hematemesis (15%). Five participants withdrew consent before capsule ingestion, and for two patients, primary endpoint data were missing. This left an intent-to-treat population of 124 patients; 110 completed the study.

Patients were asked to swallow the capsule and to lay on their left side. The PillSense is based on optical sensing technology that uses an optical signature of blood in the gut. The device differentiates blood from any other liquids that may be present. After 5-7 minutes, the device gathers and transmits data wirelessly to an external, handheld receiver that processes binary data and indicates either “blood detected” or “no blood detected” in the upper GI tract, explained Dr. Akiki.

Following the capsule reading, patients underwent EGD within 4 hours. This enabled the researchers to compare data between the two modalities. Follow-up visits were conducted on days 7, 14, and 21 to ensure the capsule had passed from the body. Endoscopists were blinded to the capsule result when reading the EGD.

Primary endpoints were the sensitivity and specificity of the device; secondary endpoints were positive predictive value, negative predictive value, successful passage of the capsule, and safety.
 

Rapid and accurate

The researchers determined the efficiency of the capsule in correctly detecting a UGIB. The capsule’s positive and negative predictive values were 74.3% and 97.8%, respectively.

“We achieved a sensitivity of around 93% (92.9%; P = 0.024) with the PillSense capsule and a specificity of 91% (90.6%; P < .001]), which were pretty good. We also detected a range from minimal bleeding – so, speckles of blood to large amounts of active bleeding covering the entire stomach,” reported Dr. Akiki.

There were no differences in terms of patient demographics, laboratory results, or concomitant use of medications. PillSense recording time was a mean of 6.71 minutes, the time from capsule ingestion to EGD was a mean of 55 minutes, and the time to capsule passage through the GI tract was 3.6 days. Most bleeds were found to be in the stomach (18/30; 60%), followed by the duodenum (5/30; 16.6%).

Various capsules for detecting UGIB are under development or are already available, but unlike some of the others, “[the PillSense] is not a video capsule,” said Dr. Akiki. “It does not take pictures at all but is more of a photo sensor capsule that measures the absorption of wavelengths.”

This explains why the PillSense was so rapid – results were available in around 7 minutes and did not require an interpretation by a physician, he explained. “Trained non-physician personnel can use it, and this is where it differs from other devices, such as video capsules that require someone highly trained to interpret the output. It’s an easy procedure and process to follow.”

The PillSense has value in improving workflow, Dr. Akiki said. “If we had someone come in during the night with a suspected upper GI bleed, we could give them the capsule, determine if they need an EGD or not, and potentially postpone it to a time – say, the morning, when more resources are available – freeing up the night for emergency cases. It helps me, as a physician, to determine which patients to send to EGD immediately or which to wait.”

He added that more studies are needed in the postmarketing phase to understand optimal use of the device and to define the exact clinical pathway for optimal implementation.

The device was approved by the U.S. Food and Drug Administration in February. Dr. Akiki noted that there were no adverse events or deaths related to the capsule.

Co-moderator, Philip Chiu, MD, a gastroenterologist from the Chinese University of Hong Kong, said, “It’s an interesting study, because sometimes we can’t differentiate by clinical symptoms as to whether this is a problem of continuous bleeding or something else. The capsule might help us in our decision-making in this respect and help determine whether we should scope the patients or just manage conservatively.”

Dr. Akiki and Dr. Chiu have disclosed no relevant financial relationships.

COPENHAGEN – A real-time, blood-sensing capsule that detects upper gastrointestinal bleeding (UGIB) is safe and effective for patients before undergoing upper endoscopy, according to results from the first U.S.-based open-label, single-arm comparative clinical trial of a novel bleeding sensor for patients with suspected UGIB. It is also the largest such trial.

The capsule (PillSense, EnteraSense) is rapidly deployed, safe to use, and easy to interpret, study researchers say. In under 7 minutes, it correctly detected the presence of blood in 26 of 28 patients and its absence in 87 of 96 patients, as confirmed afterward by esophagogastroduodenoscopy (EGD).

“The use of the PillSense system will positively impact patient outcomes by providing early diagnosis, triaging, and directing care for UGIB,” said Karl Akiki, MD, study lead, who is in the division of gastroenterology and hepatology at the Mayo Clinic, Rochester, Minn. He presented the results at the annual United European Gastroenterology Week.

AT UEG WEEK 2023

COPENHAGEN – Risankizumab shows noninferiority for clinical remission at week 24, and superiority of endoscopic remission at week 48 when compared with ustekinumab in patients with moderately to severely active Crohn’s disease (CD) who have failed one or more anti–tumor necrosis factor (anti-TNF) therapies, according to the results of the phase 3 SEQUENCE trial.

Secondary endpoints – presented for the first time at the United European Gastroenterology Week 2023 – also showed superiority of risankizumab (Skyrizi, AbbVie), an interleulin-23 inhibitor, over ustekinumab (Stelara), an IL-12 and IL-23 inhibitor, for clinical remission at week 48 (60.8% vs. 40.8%) and a statistically significant endoscopic response also favoring risankizumab at weeks 24 and 48.

“With endoscopic remission we see that with a single agent we have doubled the endoscopic remission rate by moving from 16% to 31% with risankizumab [at week 48],” said Laurent Peyrin-Biroulet, MD, PhD, a gastroenterologist specializing in inflammatory bowel disease at Nancy University Hospital, France. “Superiority for sure was met.”

“This sort of thing happens once in your career,” noted Dr. Peyrin-Biroulet, who presented the results of the study at the meeting. “It’s totally amazing that everything you see here was in favor of risankizumab.

“Already we see the efficacy signal in the proportion of premature discontinuations at 2% vs. 13% due to lack of efficacy [in risankizumab and ustekinumab, respectively],” he said. “This is due to drug failure.”

Risankizumab is an IL-23 inhibitor that selectively blocks the cytokine IL-23, thought to be linked to a number of chronic immune-mediated diseases, by binding to its p19 subunit. It is the first IL-23 inhibitor to receive approval from the U.S. Food and Drug Administration in June 2022 for moderately to severely active CD based on data from the ADVANCE, MOTIVATE, and FORTIFY trials.

Risankizumab and ustekinumab head-to-head

The phase 3, open-label, multicenter, randomized, clinical trial evaluated risankizumab vs. ustekinumab through week 48 in patients with moderately to severely active CD.

Participants were required to have a CD Activity Index (CDAI) score of 220 to 450 at baseline, a Simple Endoscopic Score for Crohn’s Disease (SES-CD) of 6 or more for ileocolonic or colonic disease (and of 4 or more for isolated ileal disease), excluding the presence of a narrowing component, plus an average daily stool frequency of four or more and/or average daily abdominal pain score of 2 or more. They were also required to have previously failed one or more anti-TNF therapies.

Randomization was stratified by the number of anti-TNF therapies failed (one or more than one), and steroid use at baseline; steroids were then tapered from week 2. Two primary endpoints comprised clinical remission at week 24 (defined as CDAI < 150, noninferiority margin within 10% of risankizumab vs ustekinumab in 50% of participants), and also endoscopic remission (SES-CD of 4 or less, and at least a 2-point reduction vs. baseline and no subscore greater than 1 in any individual component) at week 48 demonstrating superiority of risankizumab vs ustekinumab.

Secondary endpoints included clinical remission at week 48, endoscopic response at weeks 48 and 24, steroid-free endoscopic remission at week 48, and steroid-free clinical remission at week 48 (all tested for superiority of risankizumab vs ustekinumab).

Intravenous risankizumab at 600 mg was given at weeks 0, 4 , and 8 followed by subcutaneous risankizumab at a 360-mg maintenance dose every 8 weeks through week 48 (n = 255). Participants who completed the week-48 visit continued on subcutaneous risankizumab for up to an additional 220 weeks. Ustekinumab was given as a weight-based, intravenous induction dose at week 0 followed by a 90-mg subcutaneous dose every 8 weeks, starting at week 8 through week 48 (n = 265). Participants received open-label drug administration but efficacy assessment was blinded.

Superiority of risankizumab

Both primary endpoints were met. For clinical remission at week 24, in half of the patients enrolled, rates were 58.6% (75/128) for risankizumab and 39.5% (54/137) for ustekinumab, for a difference of 18.4% [95% confidence interval, 6.6-30.3], meaning that noninferiority was met within the predefined margin of 10%. The second primary endpoint of endoscopic remission at week 48 showed rates of 31.8% (81/255) for risankizumab and 16.2% (43/265) for ustekinumab (P < .0001 for superiority).

Risankizumab was found to be superior to ustekinumab for all secondary endpoints (all with P < .0001). Steroid-free endoscopic remission at week 48 showed a 16% difference, and steroid-free clinical remission at week 48 showed a 20% difference – both in favor of risankizumab.

In addition, more participants on risankizumab completed the study (89.4%) than those on ustekinumab (74.0%), Dr. Peyrin-Biroulet reported.

Adverse event rates (events per 100 person-years) were comparable between the two drugs at 341.2 for risankizumab and 282.7 for ustekinumab. For risankizumab, no new safety risks were observed, and those recorded were consistent with the known safety profile. Serious adverse events occurred in 10% of risankizumab-treated patients, and 17% of ustekinumab-treated patients.

“We know the safety of IL-23 inhibitors is good,” said Dr. Peyrin-Biroulet. “If we look at all adverse events there was no difference across arms, and in terms of serious adverse events, it was in favor of risankizumab because a CD flare is considered a serious adverse event.”

Session comoderator, Alessandro Armuzzi, MD, head of the Inflammatory Bowel Disease Center at the IRCCS Humanitas Research Hospital in Milan, commented on the findings. “The results look in favor of risankizumab – all the endpoints were met, not only the co-endpoints but also the secondary endpoints too,” he said.

These results, showing a preference for risankizumab, have value in helping clinicians with the sequence of therapies when patients with Crohn’s disease have failed one or more TNF inhibitor, said Dr. Armuzzi.

No funding for this study was disclosed. Dr. Peyrin-Biroulet has disclosed receiving fees from Galapagos, AbbVie, Janssen, Genentech, Alimentiv, Ferring, Tillots, Celltrion, Takeda, Pfizer, Index, Sandoz, Celgene, Biogen, SamsungBioepis, Inotrem, Allergan, MSD, Roche, Arena, Gilead, Amgen, BMS, Vifor, Norgine, Mylan, Lilly, Fresenius Kabi, OSEImmunotherapeutics, Enthera, Theravance, Pandion, Gossamer, Viatris, ThermoFisher, ONOPharma, Mopac, Cytoki, Morphic, Prometheus, and Applied MolecularTransport.

Adverse event rates (events per 100 person-years) were comparable between the two drugs at 341.2 for risankizumab and 282.7 for ustekinumab. For risankizumab, no new safety risks were observed, and those recorded were consistent with the known safety profile. Serious adverse events occurred in 10% of risankizumab-treated patients, and 17% of ustekinumab-treated patients.

“We know the safety of IL-23 inhibitors is good,” said Dr. Peyrin-Biroulet. “If we look at all adverse events there was no difference across arms, and in terms of serious adverse events, it was in favor of risankizumab because a CD flare is considered a serious adverse event.”

Session comoderator, Alessandro Armuzzi, MD, head of the Inflammatory Bowel Disease Center at the IRCCS Humanitas Research Hospital in Milan, commented on the findings. “The results look in favor of risankizumab – all the endpoints were met, not only the co-endpoints but also the secondary endpoints too,” he said.

These results, showing a preference for risankizumab, have value in helping clinicians with the sequence of therapies when patients with Crohn’s disease have failed one or more TNF inhibitor, said Dr. Armuzzi.
