Then and Now: A ‘lifetime’ of advancement in upper GI tract
Fifteen years is a lifetime for the advancement of medical research. This seems particularly true for upper GI tract disorders.
In 2007, eosinophilic esophagitis was a rare disease; limited clinical data were available describing the symptoms, demographic characteristics, and endoscopic findings. Treatment was guided mostly by uncontrolled patient series for topical steroids and comprehensive diet exclusion therapy. Today, the molecular, genetic, and evolving microbiome’s contributions to EoE are being elucidated. EoE is recognized as one of the most common diseases in our practice, and rigorously performed controlled trials of steroids and biologics (including Food and Drug Administration–approved dupilumab) guide our treatment. Diet has also become easier with the identification of a single food antigen as the cause in 40% of EoE patients. The most pressing need is for a test that’s reliable and less invasive than endoscopy to assess and monitor treatment.
Barrett’s esophagus was of great concern 15 years ago and has surged in importance because of the increasing incidence of Barrett’s and esophageal adenocarcinoma, likely emphasized by the obesity epidemic. Sadly, survival with esophageal adenocarcinoma has changed little because most patients present with advanced stages. Multiple studies are questioning guideline recommendations because of their low yield and high expense. Fortunately, a range of easier screening tools is being tested, including sponge on string devices, video capsules, transnasal endoscopy, and the electronic “nose.” These can provide more widespread screening in broader populations of patients at risk who may lack heartburn or classic demographics. In 2007 there was little endoscopic therapy; now, the gastroenterologist has a robust armamentarium with multiple methods for mucosal ablation and resection achieving cure and sparing the patient an esophagectomy. Tissue biomarkers continue to be elucidated and are being applied to clinical practice.
For esophageal motility disorders, manometric data were obtained through a primitive water-infused system. With high-resolution manometry, the Chicago Classification, and impedance planimetry, our ability to precisely define, understand, and treat these disorders has been greatly enhanced.
In prior decades, the association of H. pylori to gastric cancer was noted but landmark trials and meta-analyses have strongly linked eradication of H. pylori with reduction in gastric cancer. These include broad population studies from Taiwan and the U.S. Veterans Health Administration, as well as a Cochrane review. These data have reinforced the need to search for and eradicate H. pylori infection. Although antibiotic resistance is rampant, newer antibiotic combinations including nitazoxanide, levofloxacin, rifabutin, and tinidazole have been proven effective. Potassium-competitive acid blockers may also augment effective eradication.
Endoscopy itself is one of the greatest areas of advancement in upper GI disease since 2007. What was once limited to biopsy, removal of polyps, and control of gastrointestinal bleeding, now has a breathtaking range of diagnostic and therapeutic capabilities. Who could imagine being able to perform bariatric procedures, create a gastrojejunostomy, treat a Zenker’s diverticulum, or drain extraluminal abscesses through an endoscope? With description of the technique of submucosal tunneling, endoscopic mucosal resection has been extended to submucosal dissection for more advanced cancers and benign tumors. This technique has also revolutionized the treatment of achalasia with peroral endoscopic myotomy, a procedure found equivalent to laparoscopic myotomy in controlled trials. Finally, artificial intelligence has taken endoscopic imaging by storm, and the accuracy with which we will diagnose premalignant lesions of the esophagus and stomach should significantly increase our abilities to prevent and treat early cancers.

Baclofen shows limited role in GERD
A randomized clinical trial indicated that add-on baclofen may be of benefit to patients on adequate doses of proton pump inhibitors (PPI) with refractory gastroesophageal reflux disease (GERD). However, the benefit was limited to a subset of patients with positive symptom association probability (SAP), which was calculated using 24-hour combined multichannel intraluminal impedance and pH monitoring (24h pH-MII).
“Empirical add-on therapy with baclofen in GERD patients with persisting typical symptoms in spite of double-dose PPI therapy does not seem justified. The use of baclofen should be limited to patients who display a positive SAP for typical reflux symptoms (heartburn and/or regurgitation) during PPI therapy,” researchers led by Ans Pauwels, PhD, MPharmSc, of the Catholic University of Leuven (Belgium) concluded in Alimentary Pharmacology & Therapeutics.
Asked to comment, Philip Katz, MD, professor of medicine and director of GI Function Laboratories at Weill Cornell Medicine and a co-author of some recent GERD guidelines said, “What it tells me is that baclofen may be useful to a patient population that has an accurate diagnosis of reflux hypersensitivity. The difficulty with this study is that the patients you would expect to be helped by baclofen, which were patients who satisfied the criteria for true GERD, didn’t have any improvement.”
PPIs are effective at reducing acid reflux and promoting esophageal healing in GERD patients, but they have little effect on non-acid reflux. Heartburn is most often tied to acid reflux, but regurgitation occurs with similar frequency during both acid and non-acid episodes.
Up to 50% of patients still have reflux despite PPI treatment, and many of these patients will respond to higher PPI doses. However, those who don’t respond are left with few treatment choices.
Reflux events generally occur during transient lower esophageal sphincter relaxations (TLOSRs), and this mechanism is predominant in mild and moderate GERD. A gamma-aminobutyric acid type B receptor agonist, baclofen reduces TLOSRs and associated reflux episodes following meals. Few studies have examined the clinical potential of baclofen in refractory GERD, and it generally is only used after determining that ongoing weakly acidic reflux is responsible for symptoms, using 24h pH-MII.
The study included about 60 patients who underwent 24-hour monitoring while taking a PPI twice daily. Over a 2-week run-in period, participants filled out daily diaries and were randomized to placebo or baclofen 3 times daily over 4 weeks. The baclofen dose was 5 mg for the first week, then 10 mg for the next 3 weeks.
At the end of treatment, 24h pH-MII was repeated. The researchers found no significant decreases in non-acid reflux events after placebo treatment (corrected P = .74) and a trend towards a reduction following baclofen treatment (corrected P = .12).
Although the results won’t change his practice significantly, Dr. Katz congratulated the authors on the thoroughness of the study. However, he noted that wellbeing is a difficult endpoint to study: “The importance of this study to me is that it confirms that baclofen shouldn’t be used empirically, since there was no improvement in patients who were functional, and it was hard to find improvement in any group. This reinforces the need for a thorough work-up of the patient with GERD.”
The drug also had some tolerability issues: 16% of patients on baclofen discontinued its use because of adverse events such as drowsiness, dizziness, headache, and nausea.
An important limitation of the study is that the researchers recruited patients with persistent GERD symptoms despite use of PPIs. “Calling it refractory GERD is tricky because they didn’t prove they had GERD before they were enrolled in the study. That being said, the researchers did a very rigorous, very careful study to try and find potentially some place that baclofen might benefit patients,” said Dr. Katz.
The authors of the study and Dr. Katz have no relevant financial disclosures.

New eosinophilic esophagitis severity score may guide treatment
The American Gastroenterological Association has developed a new index to help clinicians gauge the severity of eosinophilic esophagitis (EoE), offering a tool to physicians that experts say has been lacking in the field and should help better guide treatment.
The index – known as I-SEE, for Index of Severity for Eosinophilic Esophagitis – was developed after an exhaustive review of the literature, and allows clinicians to calculate a score based on symptoms, complications, endoscopy findings, and histology. It was published in Gastroenterology and the Journal of Allergy and Clinical Immunology.
In other eosinophilic disorders, such as asthma, there are well-prescribed treatment pathways based on the severity, said Evan Dellon, MD, MPH, professor of gastroenterology and hepatology at the University of North Carolina at Chapel Hill.
“That is the ultimate aspiration for I-SEE – assess EoE severity, have that severity linked to certain outcomes and therefore be associated with certain treatment and monitoring recommendations, then reassess the patient severity in a standardized way, and then make additional treatment and monitoring changes if needed,” he said in an interview. “However, to get there a lot more research into the use of the tool will be needed.”
With support from the AGA, a multidisciplinary group – including adult and pediatric specialists in gastroenterology, asthma and immunology, pathology, epidemiology, and basic and translational research, as well as patient advocates – broke into teams to assess the available literature, developed consensus on the factors to be used, and developed consensus on the scoring system.
New ways have been developed over the years to assess patients’ responses to treatments and gauge their disease activity, from patient-reported outcomes to endoscopic assessment platforms and metrics using histology. But all of this information hadn’t been synthesized into a tool that clinicians would find practical to use, the expert group said in its paper describing the index.
How it works
The index divides criteria into three main categories: symptoms and complications, inflammatory features, and fibrostenotic features.
In the symptoms and complications category, points are assessed based on whether symptoms are weekly, daily, or several times a day and whether problems such as food impaction or esophageal perforations are present.
Inflammatory features include localized or diffuse edema or furrows on endoscopy and eosinophil counts.
Fibrostenotic scoring items include features such as rings or strictures and how constricting they are, as well as basal zone hyperplasia and lamina propria fibrosis.
Each feature is assigned a score of 1-15. An overall score of 0 points would be considered inactive disease; 1-6 is mildly active disease; 7-14 is moderately active disease; and 15 or more is severely active disease.
Someone with daily symptoms (2 points) and localized edema on endoscopy (1 point) and 15-60 eosinophils per high power field (1 point) would have a total of 4 points and be considered to have mildly active disease. Someone who is 18 years of age or older with daily symptoms (2 points), food impaction with an ED visit (2 points), diffuse edema on endoscopy (2 points), 15-60 eosinophils per high power field (1 point), basal zone hyperplasia (2 points), and rings or strictures on endoscopy that don’t permit passing a standard upper endoscope (15 points), would have 24 points and be considered to have severely active disease.
The index is only just starting to be tested with patient-level data, but the first results are promising, Dr. Dellon said. He hopes incorporating endoscopic and histologic features into the index will lead to wider evaluation of these indicators of severity because they have been shown to be important clinically.
Dr. Dellon said there is a plan to develop an app that will allow the index’s “usability” to be tested across a range of practice settings and disciplines. The index will also be evaluated in existing and prospectively collected datasets.
“This will help us understand the distribution of EoE patient severity in a number of settings, as well as how severity relates to posttreatment outcomes,” he said. “Ultimately, it is possible that I-SEE could be incorporated into electronic medical records systems.”
Simplifying clinical practice
Philip Katz, MD, professor of medicine in the gastroenterology division at Weill Cornell Medicine, New York, said the index could be a step forward in the care of EoE patients.
“The way all of us make choices for these patients and how we judge where they are in terms of the ‘severity’ of their disease is not ideal, by any means,” he said. “[This] appears to be a strong attempt to simplify what we’re currently doing now and put it all in one place.”
Ease of use will be important and his practice will be evaluating that, he said. He said he hopes that software will make it practical, possibly with the necessary information able to be imported straight from the electronic health record.
“We’ll do our best to use the system data in a way that the authors have suggested,” he said. “Basically, we’ll make our own opinions as data is gathered.”
He recommended that clinicians treating EoE try to use the index and assess its performance on their own, in addition to staying aware of data that’s collected elsewhere in the field. That way, collectively, the tool will have the maximum impact on improving patient care.
“[The researchers who developed the tool] are people who have dedicated a substantial portion of their professional careers to studying this disease and are comfortable that this is a tool that will offer more value than what we’re currently doing,” he said. “Chances are, this will be much better than what we currently have.”
This new tool was developed as part of AGA’s EoE initiative: Eosinophilic Esophagitis: Expand, Optimize, Excel. View additional resources at eoe.gastro.org.
The index was developed as part of a conference that was supported by a grant from Takeda. This conference was also funded in part by the division of intramural research at National Institute of Allergy and Infectious Diseases/National Institutes of Health and supported by CEGIR (U54 AI117804). All activities and products resulting from this conference were independently developed with no involvement or input from the funder. The authors disclosed relationships with various industry entities, including Takeda. None of the other relationships were relevant to this work. Dr. Katz consults with Phathom, Sebela Pharmaceuticals, and AstraZeneca.

In other eosinophilic disorders, such as asthma, there are well-prescribed treatment pathways based on the severity, said Evan Dellon, MD, MPH, professor of gastroenterology and hepatology at the University of North Carolina at Chapel Hill.
“That is the ultimate aspiration for I-SEE – assess EoE severity, have that severity linked to certain outcomes and therefore be associated with certain treatment and monitoring recommendations, then reassess the patient severity in a standardized way, and then make additional treatment and monitoring changes if needed,” he said in an interview. “However, to get there a lot more research into the use of the tool will be needed.”
With support from the AGA, a multidisciplinary group – including adult and pediatric specialists in gastroenterology, asthma and immunology, pathology, epidemiology, and basic and translational research, as well as patient advocates – broke into teams to assess the available literature, developed consensus on the factors to be used, and developed consensus on the scoring system.
New ways have been developed over the years to assess patients’ responses to treatments and gauge their disease activity, from patient-reported outcomes to endoscopic assessment platforms and metrics using histology. But all of this information hadn’t been synthesized into a tool that clinicians would find practical to use, the expert group said in its paper describing the index.
How it works
The index divides criteria into three main categories: symptoms and complications, inflammatory features, and fibrostenotic features.
In the symptoms and complications category, points are assessed based on whether symptoms are weekly, daily, or several times a day and whether problems such as food impaction or esophageal perforations are present.
Inflammatory features include localized or diffuse edema or furrows on endoscopy and eosinophil counts.
Fibrostenotic scoring items include features such as rings or strictures and how constricting they are, as well as basal zone hyperplasia and lamina propria fibrosis.
Each feature is assigned a score of 1-15. An overall score of 0 points would be considered inactive disease; 1-6 is mildly active disease; 7-14 is moderately active disease; and 15 or more is severely active disease.
Someone with daily symptoms (2 points) and localized edema on endoscopy (1 point) and 15-60 eosinophils per high power field (1 point) would have a total of 4 points and be considered to have mildly active disease. Someone who is 18 years of age or older with daily symptoms (2 points), food impaction with an ED visit (2 points), diffuse edema on endoscopy (2 points), 15-60 eosinophils per high power field (1 point), basal zone hyperplasia (2 points), and rings or strictures on endoscopy that don’t permit passing a standard upper endoscope (15 points), would have 24 points and be considered to have severely active disease.
The index is only just starting to be tested with patient-level data, but the first results are promising, Dr. Dellon said. He hopes incorporating endoscopic and histologic features into the index will lead to wider evaluation of these indicators of severity because they have been shown to be important clinically.
Dr. Dellon said there is a plan to develop an app that will allow the index’s “usability” to be tested across a range of practice settings and disciplines. The index will also be evaluated in existing and prospectively collected datasets.
“This will help us understand the distribution of EoE patient severity in a number of settings, as well as how severity relates to posttreatment outcomes,” he said. “Ultimately, it is possible that I-SEE could be incorporated into electronic medical records systems.”
Simplifying clinical practice
Philip Katz, MD, professor of medicine in the gastroenterology division at Weill Cornell Medicine, New York, said the index could be a step forward in the care of EoE patients.
“The way all of us make choices for these patients and how we judge where they are in terms of the ‘severity’ of their disease is not ideal, by any means,” he said. “[This] appears to be a strong attempt to simplify what we’re currently doing now and put it all in one place.”
Ease of use will be important and his practice will be evaluating that, he said. He said he hopes that software will make it practical, possibly with the necessary information able to be imported straight from the electronic health record.
“We’ll do our best to use the system data in a way that the authors have suggested,” he said. “Basically, we’ll make our own opinions as data is gathered.”
He recommended that clinicians treating EoE try to use the index and assess its performance on their own, in addition to staying aware of data that’s collected elsewhere in the field. That way, collectively, the tool will have the maximum impact on improving patient care.
“[The researchers who developed the tool] are people who have dedicated a substantial portion of their professional careers to studying this disease and are comfortable that this is a tool that will offer more value than what we’re currently doing,” he said. “Chances are, this will be much better than what we currently have.”
This new tool was developed as part of AGA’s EoE initiative: Eosinophilic Esophagitis: Expand, Optimize, Excel. View additional resources at eoe.gastro.org.
The index was developed as part of a conference that was supported by a grant from Takeda. This conference was also funded in part by the division of intramural research at National Institute of Allergy and Infectious Diseases/National Institutes of Health and supported by CEGIR (U54 AI117804). All activities and products resulting from this conference were independently developed with no involvement or input from the funder. The authors disclosed relationships with various industry entities, including Takeda. None of the other relationships were relevant to this work.

Eosinophilic diseases often overlap, raising costs
Eosinophilic GI diseases (EGIDs) often overlap with other eosinophil-associated diseases (EADs), which leads to greater health care costs, according to an analysis of the U.S. Optum Clinformatics claims database.
EADs have gained increased attention in recent years. They include eosinophilic esophagitis (EoE), eosinophilic asthma, bullous pemphigoid, eosinophilic granulomatosis with polyangiitis, eosinophilic gastritis/gastroenteritis (EG/EGE), and a subset of non–cystic fibrosis bronchiectasis. All involve infiltration of eosinophils, but the exact immune mechanisms behind them seem to vary and are poorly understood, according to Justin Kwiatek, PharmD, who presented the results at the annual Digestive Disease Week® (DDW).
“We do know that the suitable course of treatment is dependent on the organs impacted. From this study, we also know that EoE mostly exists on its own, with only a small portion also being diagnosed with asthma, while overlap with other EGIDs tends to be higher. This could be because EoE appears to be pathologically different from other EGIDs in the gastrointestinal tract such as eosinophilic gastritis in the stomach or eosinophilic gastroenteritis in the stomach and small bowel. Eosinophils are not normally present in the esophagus but are often found in the stomach or small bowel without inflammation,” said Dr. Kwiatek, who is senior global medical affairs leader, respiratory & immunology, at AstraZeneca.
The study is important, said Dhyanesh Patel, MD, who was asked to comment on the study. “There’s been a lot of interest in eosinophilic gastrointestinal diseases recently because there is lack of a clear definition. We need to define it better because we need to figure out treatment options for the patients,” said Dr. Patel, who is an assistant professor of medicine at Vanderbilt University, Nashville, Tenn.
“It highlights that a lot of the patients that have one eosinophilic disease might have other concomitant atopic diseases. [It may be that] you can use one drug to treat all of them together, so I think it’s important to have a multidisciplinary approach where you work with an allergist and you work with an immunologist and treat their eosinophilic gastritis and their asthma together with one drug. That may help reduce medication burden,” said Dr. Patel.
The researchers analyzed records from 1,326,645 diagnosed patients with at least one EAD and at least 2 years following treatment. There were 13,872 patients with EoE, 38.4% of whom had at least one overlapping EAD. Of 1,365 patients with EG/EGE, 57.9% had at least one overlapping EAD.
EADs were associated with higher Charlson Comorbidity Index scores and high blood eosinophil levels (≥ 300 cells/mcL) among EoE patients, but not among EG/EGE patients. Within the EoE group, female gender was linked to more EAD comorbidities: 35% of patients with only EoE were female; 45% of patients with one comorbidity were female, as were 55% of those with two comorbidities and 57% of those with three or more comorbidities. There was no such trend among patients with EG/EGE.
Total health care costs were lower in the absence of one overlapping EAD among both EoE ($2,061 vs. $3,766 per patient per month) and EG/EGE patients ($2,860 vs. $4,053). Costs went up with more overlap: $8,572 for EoE and three or more other EADs, and $10,397 for EG/EGE and three or more other EADs. These costs were largely driven by outpatient care.
“The data shows that patients with eosinophilic gastritis and eosinophilic gastroenteritis are more likely to have overlapping eosinophilic conditions, such as asthma. When diagnosing a patient with EG or EGE, it’s important to monitor any new symptoms closely and to educate them about the risk factors. This is particularly true for patients with elevated blood eosinophil counts. Accounting for comorbidities and establishing a treatment plan early can help to manage the higher health care spend for patients with overlapping conditions,” said Dr. Kwiatek.

H. pylori antibiotics briefly disrupt gut microbiome
SAN DIEGO – Treatments to eradicate Helicobacter pylori (H. pylori) infections do increase the antibiotic resistance of the gut microbiota, but for only a few months, researchers reported at Digestive Disease Week® (DDW).
The finding applies similarly to levofloxacin quadruple therapy and bismuth quadruple therapy, both of which are equally efficacious as second-line treatments, said Jyh-Ming Liou, MD, PhD, clinical professor of internal medicine at National Taiwan University in Taipei.
This provides some reassurance that increased use of antibiotics to treat these infections won’t cause long-term disruptions to the patients’ microbiomes, said Dr. Liou.
“Maybe if we have indications for antibiotic treatment, then we don’t worry about the emergence of resistance in our bodies,” he said. “But the accumulation of antibodies in the environment may induce bacteria to mutate, so maybe we still need cautious use of antibiotics.”
H. pylori infections are becoming harder to treat as more strains develop resistance to antibiotics, leading physicians to use regimens with multiple agents. This in turn has raised concerns that gut microbiota could be disrupted, with pathogens potentially developing their own resistance.
To explore these risks, Dr. Liou and colleagues recruited adults whose H. pylori infections were not successfully eradicated.
They randomly assigned 280 patients each to one of two second-line therapies, levofloxacin quadruple or bismuth quadruple. At baseline, the researchers could not find any statistically significant differences in the two groups’ demographics, cigarette and alcohol use, or ulcers, as well as antibiotic resistance in patients’ microbiome between the groups.
Levofloxacin quadruple therapy consisted of esomeprazole 40 mg and amoxicillin 1 g for the first 7 days, followed by esomeprazole 40 mg, metronidazole 500 mg, and levofloxacin 250 mg for another 7 days (all twice daily).
Bismuth quadruple therapy consisted of esomeprazole 40 mg twice daily, bismuth tripotassium dicitrate 300 mg four times a day, tetracycline 500 mg four times a day, and metronidazole 500 mg three times a day, for 10 days.
The researchers collected stool samples at baseline, week 2, week 8, and 1 year after eradication therapy and analyzed them for microbiota diversity and antibiotic susceptibility.
The H. pylori eradication rates were almost the same in the two second-line therapies: 87.9% for levofloxacin quadruple and 87.5% for bismuth quadruple. When they were used as third-line (rescue) therapies, the success rates were also statistically the same, and the cumulative second-line and third-line eradication rate was 95.6% for levofloxacin quadruple and 96.6% for bismuth quadruple.
The two treatments did differ in adverse events with 48.4% for levofloxacin quadruple and 77.3% for bismuth quadruple, which was statistically significant (P < .0001).
After a year, H. pylori reinfected 2.5% of the levofloxacin group and 3% of the bismuth quadruple group.
The researchers used metagenomic sequencing to examine the bacteria in the patients’ microbiome for antibiotic resistance. Using 16S rRNA sequencing, they found that the proportion of genera and species with significant changes in abundance at 2 weeks after treatment compared with baseline was 52.4% for levofloxacin quadruple therapy versus 45.1% for bismuth quadruple therapy.
However, 8 weeks after treatment, the proportion with significant changes had dropped to 5.8% for the levofloxacin group and 21.5% for the bismuth group. And at the end of a year, they had further dropped to 0.9% for the levofloxacin group and 8.4% for the bismuth group.
“It was generally reassuring that, even after giving these combinations of different antibiotics, eventually it doesn’t seem to affect the resistance pattern in bacteria lower down in the gut,” said session moderator Steven Moss, MD, professor of medicine at Brown University in Providence, R.I.
Still, continuing to pile on more and more antibiotics to treat H. pylori infections won’t work forever because H. pylori strains are themselves developing resistance so rapidly, he said. “We’re certainly going to have worse eradications in the future unless we can come up with new tricks.”
A hopeful development are new techniques to test H. pylori for resistance to specific antibiotics before initiating treatment, said Dr. Moss.
Dr. Moss consults with companies developing H. pylori therapies and diagnostics. Dr. Liou reported no relevant financial interests.

More evidence dementia not linked to PPI use in older people
Controversy regarding the purported link between the use of proton pump inhibitors (PPIs) or histamine H2 receptor antagonists (H2RAs) and risk for dementia continues.
Adding to the “no link” column comes new evidence from a study presented at the annual Digestive Disease Week® (DDW) .
Among almost 19,000 people, no association was found between the use of these agents and a greater likelihood of incident dementia, Alzheimer’s disease, or cognitive decline in people older than 65 years.
“We found that baseline PPI or H2RA use in older adults was not associated with dementia, with mild cognitive impairment, or declines in cognitive scores over time,” said lead author Raaj Shishir Mehta, MD, a gastroenterology fellow at Massachusetts General Hospital in Boston.
“While deprescribing efforts are important, especially when medications are not indicated, these data provide reassurance about the cognitive impacts of long-term use of PPIs in older adults,” he added.
Growing use, growing concern
As PPI use has increased worldwide, so too have concerns over the adverse effects from their long-term use, Dr. Mehta said.
“One particular area of concern, especially among older adults, is the link between long-term PPI use and risk for dementia,” he said.
Igniting the controversy was a February 2016 study published in JAMA Neurology that showed a positive association between PPI use and dementia in residents of Germany aged 75 years and older. Researchers linked PPI use to a 44% increased risk of dementia over 5 years.
The 2016 study was based on claims data, which can introduce “inaccuracy or bias in defining dementia cases,” Dr. Mehta said. He noted that it and other previous studies also were limited by an inability to account for concomitant medications or comorbidities.
To overcome these limitations in their study, Dr. Mehta and colleagues analyzed medication data collected during in-person visits and asked experts to confirm dementia outcomes. The research data come from ASPREE, a large aspirin study of 18,846 people older than 65 years in the United States and Australia. Participants were enrolled from 2010 to 2014. A total of 566 people developed incident dementia during follow-up.
The researchers had data on alcohol consumption and other lifestyle factors, as well as information on comorbidities, hospitalizations, and overall well-being.
“Perhaps the biggest strength of our study is our rigorous neurocognitive assessments,” Dr. Mehta said.
They assessed cognition at baseline and at years 1, 3, 5, and 7 using a battery of tests. An expert panel of neurologists, neuropsychologists, and geriatricians adjudicated cases of dementia, in accordance with DSM-IV criteria. If the diagnosis was unclear, they referred people for additional workup, including neuroimaging.
Cox proportional hazards, regression, and/or mixed effects modeling were used to relate medication use with cognitive scores.
All analyses were adjusted for age, sex, body mass index, alcohol use, family history of dementia, medications, and other medical comorbidities.
At baseline, PPI users were more likely to be White, have fewer years of education, and have higher rates of hypertension, diabetes, and kidney disease. This group also was more likely to be taking five or more medications.
Key points
During 80,976 person-years of follow-up, there were 566 incident cases of dementia, including 235 probable cases of Alzheimer’s disease and 331 other dementias.
Baseline PPI use, in comparison with nonuse, was not associated with incident dementia (hazard ratio, 0.86; 95% confidence interval, 0.70-1.05).
“Similarly, when we look specifically at Alzheimer’s disease or mixed types of dementia, we find no association between baseline PPI use and dementia,” Dr. Mehta said.
When they excluded people already taking PPIs at baseline, they found no association between starting PPIs and developing dementia over time.
Secondary aims of the study included looking for a link between PPI use and mild cognitive impairment or significant changes in cognition over time. In both cases, no association emerged. PPI use at baseline also was not associated with cognitive impairment/no dementia (also known as mild cognitive impairment) or with changes in overall cognitive test scores over time.
To determine whether any association could be a class effect of acid suppression medication, they assessed use of H2RA medications and development of incident dementia. Again, the researchers found no link.
A diverse multinational population from urban and rural areas was a strength of the study, as was the “very rigorous cognitive testing with expert adjudication of our endpoints,” Dr. Mehta said. In addition, fewer than 5% of patients were lost to follow-up.
In terms of limitations, this was an observational study “so residual confounding is always possible,” he added. “But I’ll emphasize that we are among the largest studies to date with wealth of covariates.”
Why the different findings?
The study was “really well done,” session moderator Paul Moayyedi, MD, said during the Q&A session at DDW 2022.
Dr. Moayyedi, a professor of medicine at McMaster University, Hamilton, Ont., asked Dr. Mehta why he “found absolutely no signal, whereas the German study did.”
“It’s a good question,” Dr. Mehta responded. “If you look across the board, there have been conflicting results.”
The disparity could be related to how researchers conducting claims data studies classify dementia, he noted.
“If you look at the nitty-gritty details over 5 years, almost 40% of participants [in those studies] end up with a diagnosis of dementia, which is quite high,” Dr. Mehta said. “That raises questions about whether the diagnosis of dementia is truly accurate.”
Dr. Mehta and Dr. Moayyedi reported no relevant financial relationships.

Controversy regarding the purported link between the use of proton pump inhibitors (PPIs) or histamine H2 receptor antagonists (H2RAs) and risk for dementia continues.
Adding to the “no link” column comes new evidence from a study presented at the annual Digestive Disease Week® (DDW) .
Among almost 19,000 people, no association was found between the use of these agents and a greater likelihood of incident dementia, Alzheimer’s disease, or cognitive decline in people older than 65 years.
“We found that baseline PPI or H2RA use in older adults was not associated with dementia, with mild cognitive impairment, or declines in cognitive scores over time,” said lead author Raaj Shishir Mehta, MD, a gastroenterology fellow at Massachusetts General Hospital in Boston.
“While deprescribing efforts are important, especially when medications are not indicated, these data provide reassurance about the cognitive impacts of long-term use of PPIs in older adults,” he added.
Growing use, growing concern
As PPI use has increased worldwide, so too have concerns over the adverse effects from their long-term use, Dr. Mehta said.
“One particular area of concern, especially among older adults, is the link between long-term PPI use and risk for dementia,” he said.
Igniting the controversy was a February 2016 study published in JAMA Neurology that showed a positive association between PPI use and dementia in residents of Germany aged 75 years and older. Researchers linked PPI use to a 44% increased risk of dementia over 5 years.
The 2016 study was based on claims data, which can introduce “inaccuracy or bias in defining dementia cases,” Dr. Mehta said. He noted that it and other previous studies also were limited by an inability to account for concomitant medications or comorbidities.
To overcome these limitations in their study, Dr. Mehta and colleagues analyzed medication data collected during in-person visits and asked experts to confirm dementia outcomes. The research data come from ASPREE, a large aspirin study of 18,846 people older than 65 years in the United States and Australia. Participants were enrolled from 2010 to 2014. A total of 566 people developed incident dementia during follow-up.

FDA approves first drug for eosinophilic esophagitis
The U.S. Food and Drug Administration has approved dupilumab (Dupixent, Regeneron) to treat eosinophilic esophagitis (EoE) in adults and children aged 12 years and older weighing at least 40 kg.
EoE is a chronic inflammatory disorder driven by type 2 inflammation that damages the esophagus and causes difficulty swallowing and eating.
Dupilumab is a monoclonal antibody that acts to inhibit part of the inflammatory pathway. It’s the first drug to be approved by the FDA for EoE.
In a phase 3 trial, dupilumab 300 mg weekly significantly improved signs and symptoms of eosinophilic esophagitis, compared with placebo, underscoring the role of type 2 inflammation in this disease, Regeneron says in a news release.
According to the company, there are roughly 160,000 patients in the United States living with EoE who are currently using treatments not specifically approved for the disease. Of those patients, about 48,000 continue to experience symptoms despite multiple treatments.
“As researchers and clinicians have gained knowledge about eosinophilic esophagitis in recent years, more cases of the disorder have been recognized and diagnosed in the U.S.,” Jessica Lee, MD, director of the Division of Gastroenterology in the FDA’s Center for Drug Evaluation and Research, said in an FDA news release.
The approval of dupilumab will “fulfill an important unmet need for the increasing number of patients with eosinophilic esophagitis,” Dr. Lee said.
The efficacy and safety of dupilumab in EoE was demonstrated in a randomized, double-blind, parallel-group, multicenter, placebo-controlled trial that included two 24-week treatment periods (parts A and B) that were conducted independently in separate groups of patients.
In both part A and B, patients received dupilumab 300 mg or placebo every week.
In part A of the trial, 60% of the 42 patients who received dupilumab achieved the predetermined level of reduction of eosinophils in the esophagus, compared with 5% of the 39 patients who received placebo, the FDA said.
Patients who received dupilumab also experienced an average improvement of 22 points in the Dysphagia Symptom Questionnaire (DSQ) score, compared with 10 points for patients who received placebo.
In part B, 59% of the 80 patients who received dupilumab achieved the predetermined level of reduction of eosinophils in the esophagus, compared with 6% of the 79 patients who received placebo.
Patients who received dupilumab also experienced an average improvement of 24 points in their DSQ score, compared with 14 points for patients who received placebo.
“Assessments incorporating the perspectives from patients with EoE supported that the DSQ score improvement in patients who received Dupixent in the clinical trial was representative of clinically meaningful improvement in dysphagia,” the FDA noted.
“Treatment for patients with eosinophilic esophagitis can be challenging, particularly with no previously approved medications,” Evan Dellon, MD, principal investigator for the phase 3 trial, said in the company news release.
“Now, patients and their doctors have a treatment option available as part of their management plan that has the potential to control symptoms, improve inflammation, and heal the changes in the esophagus caused by this progressive and burdensome disease,” added Dr. Dellon, who is professor of medicine in the division of gastroenterology and hepatology at the University of North Carolina at Chapel Hill.
The FDA granted dupilumab priority review and breakthrough therapy designations for EoE.
Dupilumab is already approved in the United States for treatment of moderate to severe atopic dermatitis in adults and children aged 6 years and older whose disease is not adequately controlled by topical prescription therapies or for whom those therapies are not advisable.
The drug is also approved as an add-on maintenance treatment for adults and children aged 6 years and older with certain types of moderate to severe asthma and as an add-on maintenance treatment for adults with inadequately controlled chronic rhinosinusitis with nasal polyposis.

Eosinophilic esophagitis (EoE) is a chronic disease requiring long-term treatment for both induction and maintenance of response. For decades, however, Food and Drug Administration–approved therapies for EoE have not been available. Dupilumab is the first drug to receive FDA approval to treat EoE. This human monoclonal antibody directed against the interleukin (IL)4 receptor–alpha component of the type 2 receptor inhibits signaling of IL4 and IL13. Dupilumab has shown efficacy in similar diseases, such as atopic dermatitis and eosinophilic asthma. In 2017 dupilumab was granted Orphan Drug designation for the potential treatment of EoE and in 2020 the FDA granted Breakthrough Therapy designation for EoE. Recent data from the phase 3 trial of dupilumab 300 mg weekly enrolling patients aged 12 years and older demonstrated a significantly greater reduction in disease symptoms, normalization of esophageal eosinophilia, and reduction in endoscopic findings by week 24 compared with placebo.
The highly anticipated approval of dupilumab marks a paradigm shift toward biologic medications for treatment of EoE when historical treatments have relied on proton pump–inhibitor therapy or topical swallowed steroids. As we await updates about availability and access of dupilumab for our patients, we can rest assured that a highly efficacious treatment is now approved and will fill an important treatment gap in EoE, particularly for patients not deriving adequate response with traditionally used strategies. With multiple clinical trials underway, this milestone likely represents the beginning of additional effective therapies (nonbiologic and biologic) that will be available for EoE.

Psychiatric illness associated with eosinophilic esophagitis
People with eosinophilic esophagitis (EoE) may run an increased risk of mood disorders, anxiety, and ADHD and should be screened for those conditions, researchers say.
“It’s important to know that there is an elevated risk of those diagnoses, so you have that in mind when you treat your patients. You can assess their quality of life and the status of their mental state,” said lead author Lovisa Röjler, MD, a pediatrician and doctoral student at Örebro (Sweden) University Hospital.
“Psychiatric disorders are not found with a blood sample or radiology examination,” she said in an interview.
The study was published online in the American Journal of Gastroenterology.
Elevated risk found
Previous studies into the relationship between EoE and anxiety and depression have conflicting conclusions.
In the hope of shedding further light, Dr. Röjler and colleagues analyzed data from Sweden’s ESPRESSO cohort, which consists of more than 6 million biopsy samples from the gastrointestinal tract that were collected from throughout the country during the years 1965-2017.
They identified 1,458 people with EoE who had not experienced psychiatric events before being diagnosed with EoE. Of these, 70% had dysphagia, and 58% had food impaction.
In the study, up to 5 reference persons (6,436 people) without EoE who were identified from the Swedish Total Population Register were matched to the patients with EoE by age, sex, county, and year of diagnosis.
Among the people with EoE, there were 106 events of psychiatric disease, at an incidence of 15.96 per 1,000 person-years versus 10.93 per 1,000 person-years (331 events) among those without EoE. This 50% increased risk for psychiatric illness for people with EoE was statistically significant (hazard ratio, 1.50; 95% confidence interval, 1.20-1.87).
To adjust for genetic and environmental confounding factors, the researchers compared the rate of psychiatric events among 1,055 people with EoE with that of siblings who did not have EoE (1,699 people). There were 74 events of psychiatric disease among the siblings (8.99 per 1000 person-years). From this the researchers calculated a 62% increased risk of psychiatric events for those with EoE (HR, 1.62; 95% CI, 1.14-2.31).
There was no difference in risk for psychiatric disorders by educational attainment, though people for whom there were no data on education were at increased risk.
There was also no difference in psychiatric risk associated with the use of steroids or proton pump inhibitors for EoE, though these medications have sometimes been linked to psychiatric disorders.
After adjusting for inflammatory bowel disease, celiac disease, and asthma, the researchers still found an increased risk of psychiatric events. Also, the people who had EoE were no more likely than the reference persons to have had psychiatric events before their diagnosis, suggesting that EoE caused the psychiatric events rather than the other way around.
Previous researchers have found a similar association with psychiatric illness in people with celiac disease and inflammatory bowel disease. The researchers speculated that people with EoE might develop psychiatric illnesses because their symptoms and treatments, such as restrictive diets, cause stress and chronic pain and thereby cause problems with education, work, and social and economic status.
Dr. Röjler recommended that clinicians use questionnaires to identify mood disorders and ADHD in their patients and then refer them to a mental health professional.
Screen for psychiatric disorders
Tiffany Taft, PsyD, a research associate professor of medicine at Northwestern University, Chicago, who was not involved in the study, agreed that patients with EoE should be screened more often for psychiatric disorders.
“We’ve found that symptom-specific anxiety is prevalent and associated with other outcomes, like quality of life, so it may not be the typical anxiety that you would diagnose from the Diagnostic and Statistical Manual of Mental Disorders,” Dr. Taft said in an interview.
While anxiety is not likely to trigger EoE, it can worsen the symptoms, she said. Sometimes helping patients make the connection between their mental health and EoE can address the anxiety itself.
“Education is good enough for a certain chunk of patients,” Dr. Taft said.
Other patients benefit from cognitive-behavioral therapy, which gives them a more realistic understanding of their situation.
“We also add in relaxation, deep breathing, and guided imagery to calm down the stress response in the body, which is part of that brain-gut connection that enhances symptom severity,” she said.
Some patients prefer medications, or they rely on medication because that is what their insurance provides, she said, adding that most patients do best with a combination of medication and talk therapy.
Ideally, people with these disorders would be referred to someone such as herself, a psychotherapist with a specialty in gastroenterology, Dr. Taft said. But there are not many people in that subspecialty, so if a gastroenterology psychologist is not available, a psychologist who specializes in treating mental illness associated with chronic diseases is a good second choice.
The study was funded by Örebro County Council and Karolinska Institutet. Dr. Röjler and Dr. Taft reported no relevant financial relationships.

People with eosinophilic esophagitis (EoE) may run an increased risk of mood disorders, anxiety, and ADHD and should be screened for those conditions, researchers say.
“It’s important to know that there is an elevated risk of those diagnoses, so you have that in mind when you treat your patients. You can assess their quality of life and the status of their mental state,” said lead author Lovisa Röjler, MD, a pediatrician and doctoral student at Örebro (Sweden) University Hospital.
“Psychiatric disorders are not found with a blood sample or radiology examination,” she said in an interview.
The study was published online in the American Journal of Gastroenterology.
Elevated risk found
Previous studies into the relationship between EoE and anxiety and depression have conflicting conclusions.
In the hope of shedding further light, Dr. Röjler and colleagues analyzed data from Sweden’s ESPRESSO cohort, which consists of more than 6 million biopsy samples from the gastrointestinal tract that were collected from throughout the country during the years 1965-2017.
They identified 1,458 people with EoE who had not experienced psychiatric events before being diagnosed with EoE. Of these, 70% had dysphagia, and 58% had food impaction.
In the study, up to 5 reference persons (6,436 people) without EoE who were identified from the Swedish Total Population Register were matched to the patients with EoE by age, sex, county, and year of diagnosis.
Among the people with EoE, there were 106 events of psychiatric disease, at an incidence of 15.96 per 1,000 person-years versus 10.93 per 1,000 person-years (331 events) among those without EoE. This 50% increased risk for psychiatric illness for people with EoE was statistically significant (hazard ratio, 1.50; 95% confidence interval, 1.20-1.87).
To adjust for genetic and environmental confounding factors, the researchers compared the rate of psychiatric events among 1,055 people with EoE with that of siblings who did not have EoE (1,699 people). There were 74 events of psychiatric disease among the siblings (8.99 per 1000 person-years). From this the researchers calculated a 62% increased risk of psychiatric events for those with EoE (HR, 1.62; 95% CI, 1.14-2.31).
There was no difference in risk for psychiatric disorders by educational attainment, though people for whom there were no data on education were at increased risk.
There was also no difference in psychiatric risk associated with the use of steroids or proton pump inhibitors for EoE, though these medications have sometimes been linked to psychiatric disorders.

Vibrating wearable device may help night time GERD
A vibrating wearable device helped people with gastroesophageal reflux disease (GERD) stay positioned on their left side while sleeping, alleviating night time reflux symptoms, compared with sham treatment, a small, randomized study suggests.
People often report having more reflux symptoms when sleeping on their right side, and experimental studies suggest that sleeping on the right side is associated with higher esophageal acid exposure time and slower esophageal acid clearance, compared with sleeping on the left side, the authors wrote.
They cite a possible cause as the stomach being above the esophagus when a person is sleeping on their right side, resulting in more reflux.
“There are two very exciting new things that can be learned,” Arjan Bredenoord, MD, PhD, a principal investigator of the study and professor of neurogastroenterology and motility at the Academic Medical Center in Amsterdam, told this news organization. “First, we show that a device that trains people to sleep on the left side really helps to relieve nocturnal reflux symptoms. Second, the study was performed completely remotely, with the patients being at home.”
“The devices were shipped to the patients. All contact was via video calling, and questionnaires were done via links in emails that were linked to secure databases to store the patients’ symptom responses,” he added.
The findings were published online in Clinical Gastroenterology and Hepatology.
A study in sleep positional therapy
Researchers performed a double-blind, randomized, sham-controlled trial in 100 patients with night time GERD symptoms who wore a programmed device (about 1.5 inches square) on their chest, midsternum.
Patients were advised to sleep on their left side and randomly assigned (1:1) either to a group whose device produced a gentle vibration when they flipped onto their right side throughout sleep or to the group whose device vibrated when they flipped to the right side but only for the first 20 minutes of use (the sham intervention).
The primary outcome for success was at least a 50% reduction in the Nocturnal Gastroesophageal Reflux Disease Symptom Severity and Impact Questionnaire (N-GSSIQ) score. Secondary outcomes included change in sleep position and reflux symptoms.
In the intention-to-treat analysis, the rate of treatment success was 44% in the intervention group versus 24% in the sham group. The risk difference was 20% (95% confidence interval, 1.8% to 38.2%; P = .03).
Treatment led to a significant avoidance of sleeping on the right side (intervention 2.2% vs. sham 23.5%; P ≤ .0001) and an increased time of sleeping on the left side (intervention 60.9% vs. sham 38.5%; P ≤ .0001).
Patients in the intervention group also had more reflux-free nights (9 nights vs. 6 nights for the sham group).
After 2 weeks of treatment, the average total N-GSSIQ scores were lower in the active device group (18.8 vs. 23.7 in the sham group; P = .04).
Most with GERD have night time symptoms
The authors pointed out that up to 80% of patients with GERD experience symptoms during the night, such as heartburn and regurgitation, which can significantly impair sleep quality and daytime functioning.
Solutions are of high interest because current measures have shortcomings.
Raising the head-end of the bed and lengthening the time between dinner and bedtime have limited effect, the authors explained. And while proton pump inhibitors are very effective for daytime symptoms, they have limited efficacy for night time reflux symptoms.
Antireflux pillows, which are designed to keep patients on their left side through the night, have been found to result in less recumbent acid exposure and less self-reported night time reflux symptoms, but they do not allow for spontaneous body movements and can be uncomfortable, they explained.
The lightweight vibration device, made by Side Sleep Technologies BV, registers the sleep position of a subject at 30-second intervals. It categorizes sleep position as supine, right, left, prone, or upright.
Michiel Allessie, CEO of Side Sleep Technologies, told this news organization that the wearable V1.0 is sold as a consumer electronic device rather than a medical device in the United Kingdom for £99. He said the company expects to sell the V1.0 in the United States starting in June, with a target price of $99.
Promising but device still needs real-world testing
When asked to comment, Philip Katz, MD, a gastroenterologist at Weill Cornell Medicine, New York, said it was a fantastic study scientifically and academically incredibly interesting, but the device is not a panacea.
Dr. Katz said he will remain skeptical until the device is tested in real life and added that it’s important to remember this is one study with 100 people.
He also wondered whether there might be an even better solution in a well-designed wedge, for example, and whether the buzzing of this product might affect sleep quality. If so, would that be worth the tradeoff?
Dr. Katz noted that busy physicians may not have the time to determine whether patients truly have nocturnal GERD or just similar symptoms. This study included people who were carefully screened by the researchers for nocturnal reflux symptoms, he pointed out.
Based on this study, Dr. Katz said he would tell patients, “You have a 50% chance to be helped because their primary outcome was met by 44%.”
He said the decision is up to the patients and comes down to this: “It’s better than nothing for sure. Is it worth $100? You tell me.”
Dr. Bredenoord said the next step is a study using pH-impedance monitoring of the esophagus to show that there is also an effect on reflux episodes.
The investigational medical devices were provided free of charge and without restrictions by Side Sleep Technologies BV. Dr. Bredenoord disclosed research funding from Nutricia, Norgine, SST, Thelial, and Bayer; speaker and/or consulting fees from Laborie, EsoCap, Medtronic, Dr. Falk Pharma, Calypso Biotech, Alimentiv, Reckett Benkiser, Regeneron, and AstraZeneca; and previously owned shares in Side Sleep Technologies BV. Another coauthor received research funding from Boston Scientific and speaker and/or consulting fees from Cook and Olympus. The remaining authors have disclosed no relevant financial relationships. Dr. Katz reported being a consultant for Phathom Pharmaceuticals and Sebela.

AGA Clinical Practice Update: Expert review on personalizing GERD management
A recent American Gastroenterological Association Clinical Practice Update for evaluation and management of gastroesophageal reflux disease (GERD) focuses on delivering personalized diagnostic and therapeutic strategies.
The document includes new advice on use of upfront objective testing for isolated extraesophageal symptoms, confirmation of GERD diagnosis prior to long-term GERD therapy even in PPI responders, as well as important elements focused on personalization of therapy.
Although GERD is common, with an estimated 30% of people in the United States experiencing symptoms, up to half of all individuals on proton pump inhibitor (PPI) therapy report incomplete symptom improvement. That could be due to the heterogeneous nature of symptoms, which may include heartburn and regurgitation, chest pain, and cough or sore throat, among others. Other conditions may produce similar symptoms or could be exacerbated by the presence of GERD.
The authors of the expert review, published in Clinical Gastroenterology and Hepatology, note that these considerations have driven increased interest in personalized approaches to the management of GERD. The practice update includes sections on how to approach GERD symptoms in the clinic, personalized diagnosis related to GERD symptoms, and precision management.
In the initial management, the authors offer advice on involving the patient in creating a care plan, patient education, and conducting a 4- to 8-week PPI trial in patients with heartburn, regurgitation, or noncardiac chest pains without accompanying alarm signals. If symptoms don’t improve to the patient’s satisfaction, dosing can be boosted to twice per day, or a more effective acid suppressor can be substituted and continued at a once-daily dose. When the response to PPIs is adequate, the dose should be reduced until the lowest effective dose is reached, or the patient could potentially be moved to H2 receptor antagonists or other antacids. However, patients with erosive esophagitis, biopsy-confirmed Barrett’s esophagus, or peptic stricture must stay on long-term PPI therapy.
The authors also gave advice on when to conduct objective testing. When a PPI trial doesn’t adequately address troublesome heartburn, regurgitation, and/or noncardiac chest pain, or if alarm systems are present, endoscopy should be employed to look for erosive reflux disease or long-segment Barrett’s esophagus as conclusive evidence for GERD. If these are absent, prolonged wireless pH monitoring while a patient is off medication is suggested. In addition, patients with extraesophageal symptoms suspected to be caused by reflux should undergo upfront objective reflux testing while off PPI therapy rather than doing an empiric PPI trial.
The authors advise that, if patients don’t have proven GERD and are continued on PPI therapy, they should be evaluated within 12 months to ensure that the therapy and dose are appropriate. Physicians should offer endoscopy with prolonged wireless reflux monitoring in the absence of PPI therapy (ideally after 2-4 weeks of withdrawal) to confirm that long-term PPI therapy is needed.
In the section on personalization of disease management, the authors note that ambulatory reflux monitoring and upper gastrointestinal endoscopy can be used to guide management of GERD. When upper GI endoscopy reveals no erosive findings and esophageal acid exposure time (AET) is less than 4% throughout all days of prolonged wireless pH monitoring, the physician can conclude that the patient has no pathologic gastroesophageal reflux and is likely to have a functional esophageal disorder. In contrast, erosive findings during upper GI endoscopy and/or AET more than 4% across at least 1 day of wireless pH monitoring suggests a GERD diagnosis.
Optimization of PPI is important among patients with GERD, and the authors stress that patients should be educated about the safety of PPI use.
Adjunctive pharmacotherapy is useful and can include alginate antacids for breakthrough symptoms, H2RAs for nocturnal symptoms, baclofen to counter regurgitation or belching, and prokinetics for accompanying gastroparesis. The choice of medications depends on the phenotype, and they should not be used empirically.
For patients with functional heartburn or reflux disease linked to esophageal hypervigilance, reflux sensitivity, or behavioral disorders, options include pharmacologic neuromodulation, hypnotherapy provided by a behavioral therapist, cognitive behavioral therapy, and diaphragmatic breathing and relaxation.
If symptoms persist despite efforts at optimization of treatments and lifestyle factors, ambulatory 24-hour pH-impedance monitoring on PPI can be used to investigate mechanistic causes, especially when there is no known antireflux barrier abnormality, but the technique requires expertise to correctly interpret. This can ensure that the symptoms are not due to reflux hypersensitivity, rumination syndrome, or a belching disorder. When symptoms are confirmed to be treatment resistant, therapy should be escalated, using a strategy that incorporates a pattern of reflux, integrity of the antireflux barrier, obesity if present, and psychological factors.
Surgical options for confirmed GERD include laparoscopic fundoplication and magnetic sphincter augmentation. Transoral incisionless fundoplication can be performed endoscopically in selected patients. For obese patients with confirmed GERD, Roux-en-Y gastric bypass is effective at reducing reflux and can be used as a salvage treatment for nonobese patients. Sleeve gastrectomy may exacerbate GERD.

A recent American Gastroenterological Association Clinical Practice Update for evaluation and management of gastroesophageal reflux disease (GERD) focuses on delivering personalized diagnostic and therapeutic strategies.
The document includes new advice on use of upfront objective testing for isolated extraesophageal symptoms, confirmation of GERD diagnosis prior to long-term GERD therapy even in PPI responders, as well as important elements focused on personalization of therapy.
Although GERD is common, with an estimated 30% of people in the United States experiencing symptoms, up to half of all individuals on proton pump inhibitor (PPI) therapy report incomplete symptom improvement. That could be due to the heterogeneous nature of symptoms, which may include heartburn and regurgitation, chest pain, and cough or sore throat, among others. Other conditions may produce similar symptoms or could be exacerbated by the presence of GERD.
The authors of the expert review, published in Clinical Gastroenterology and Hepatology, note that these considerations have driven increased interest in personalized approaches to the management of GERD. The practice update includes sections on how to approach GERD symptoms in the clinic, personalized diagnosis related to GERD symptoms, and precision management.
In the initial management, the authors offer advice on involving the patient in creating a care plan, patient education, and conducting a 4- to 8-week PPI trial in patients with heartburn, regurgitation, or noncardiac chest pains without accompanying alarm signals. If symptoms don’t improve to the patient’s satisfaction, dosing can be boosted to twice per day, or a more effective acid suppressor can be substituted and continued at a once-daily dose. When the response to PPIs is adequate, the dose should be reduced until the lowest effective dose is reached, or the patient could potentially be moved to H2 receptor antagonists or other antacids. However, patients with erosive esophagitis, biopsy-confirmed Barrett’s esophagus, or peptic stricture must stay on long-term PPI therapy.
The authors also gave advice on when to conduct objective testing. When a PPI trial doesn’t adequately address troublesome heartburn, regurgitation, and/or noncardiac chest pain, or if alarm systems are present, endoscopy should be employed to look for erosive reflux disease or long-segment Barrett’s esophagus as conclusive evidence for GERD. If these are absent, prolonged wireless pH monitoring while a patient is off medication is suggested. In addition, patients with extraesophageal symptoms suspected to be caused by reflux should undergo upfront objective reflux testing while off PPI therapy rather than doing an empiric PPI trial.
The authors advise that, if patients don’t have proven GERD and are continued on PPI therapy, they should be evaluated within 12 months to ensure that the therapy and dose are appropriate. Physicians should offer endoscopy with prolonged wireless reflux monitoring in the absence of PPI therapy (ideally after 2-4 weeks of withdrawal) to confirm that long-term PPI therapy is needed.
In the section on personalization of disease management, the authors note that ambulatory reflux monitoring and upper gastrointestinal endoscopy can be used to guide management of GERD. When upper GI endoscopy reveals no erosive findings and esophageal acid exposure time (AET) is less than 4% throughout all days of prolonged wireless pH monitoring, the physician can conclude that the patient has no pathologic gastroesophageal reflux and is likely to have a functional esophageal disorder. In contrast, erosive findings during upper GI endoscopy and/or AET more than 4% across at least 1 day of wireless pH monitoring suggests a GERD diagnosis.
Optimization of PPI is important among patients with GERD, and the authors stress that patients should be educated about the safety of PPI use.
