Finding the Best Match for MASLD Management
, according to the authors of clinical reviews who offered guidance on the pros and cons of resmetirom and semaglutide.
MASLD has become one of the most common causes of chronic liver disease due to the increased prevalence of diabetes, obesity, and other metabolic disorders, Joanne Lin, DO, an internist in the Division of Gastroenterology and Hepatology at the University of California, San Francisco, and colleagues wrote, in a review published in the Journal of Clinical Gastroenterology.
Its complexity makes MASLD challenging to manage. Metabolic, genetic, and environmental factors are involved in the disease, so patients require multidisciplinary and individualized care, Lin told GI & Hepatology News.
Weight loss, dietary changes, and exercise had long been the only treatment approach clinicians could offer patients. But the approval of two drugs — the thyroid hormone receptor-beta agonist resmetirom and the GLP-1 receptor agonist (RA) semaglutide — for patients whose MASLD has advanced to metabolic dysfunction-associated steatohepatitis (MASH) gives physicians new options for patients with severe disease.
In the review, published online before the official approval of semaglutide, Lin and colleagues proposed an algorithm to guide clinicians in choosing a pharmacological therapy for MASLD. “Resmetirom should be primarily used to reverse fibrosis for patients with MASLD and F2-F3 stages, while GLP-1 RAs are beneficial in managing metabolic comorbidities and weight loss in patients with MASLD,” the researchers concluded.
GLP-1 Power and Potential
In August 2025, the FDA approved semaglutide for MASH and cited evidence from the ESSENCE trial in its decision.
The ESSENCE study, published in The New England Journal of Medicine, showed significantly higher rates of resolution of steatohepatitis without worsening of fibrosis and reduction in liver fibrosis without worsening steatohepatitis in patients with MASH and moderate or advanced liver fibrosis who received 2.4 mg of once-weekly semaglutide compared with patients who received placebo.
The most common adverse events reported with GLP-1 RAs are gastrointestinal-related, including nausea, diarrhea, vomiting, and constipation, and are mainly mild-to-moderate and dose dependent, Lin and colleagues noted in their review.
GLP-1s have some limitations, Lin said. “GLP-1s are great for weight loss and metabolic risk reduction, but studies are still ongoing to determine their effect on liver histology and reversing fibrosis/cirrhosis,” she said. Some patients seeking these medications also have trouble obtaining them because of their popularity for weight loss, she noted.
Resmetirom Shows Success
Resmetirom has demonstrated ability to target hepatocytes and increase the hepatic metabolism of lipids, Lin and colleagues wrote in their review.
Several trials have examined resmetirom as a treatment for MASH, notably the landmark MAESTRO-NASH study , a randomized, placebo-controlled trial of nearly 1000 adults with biopsy-confirmed MASH and stage F2 or F3 fibrosis, which was the basis for the FDA’s approval of the drug in 2024. In the study, 25.9% of the patients treated with 80 mg of resmetirom and 29.9% treated with 100 mg resmetirom achieved MASH resolution with no increase in fibrosis compared with 9.7% of patients treated with placebo. In addition, 24.2% of the patients in the 80-mg resmetirom group and 25.9% of those in the 100-mg resmetirom group achieved fibrosis improvement by at least one stage without worsening of MASLD activity scores compared with 14.2% of patients treated with placebo.
The most common reported side effects from resmetirom are diarrhea or constipation, nausea or vomiting, and abdominal pain.
“The limitations of resmetirom include the absence of validated predictors for individual patient response, and no societal guidelines are available to determine when to stop the medication if ineffective,” Lin told GI & Hepatology News. In addition, resmetirom is currently only recommended for a subset of patients with F2-F3 fibrosis, based on the existing trial, she said.
Other limitations include its high cost, which restricts access to the drug for some patients, and lack of long-term safety and efficacy data, Lin added.
Weighing the Options
Comparing the emerging agents in the context of MASLD/MASH is important to help clinicians understand how different patient populations respond and guide evidence-based treatment decisions, said Hazem Ayesh, MD, an endocrinologist at Deaconess Health System, Evansville, Indiana, in an interview.
“The choice of therapy should be individualized based on comorbidities,” said Ayesh, the lead author of a 2024 review published in Biomedicines that compared resmetirom, GLP-1 agonists, and fibroblast growth factor 21 analogs.
“For example, a GLP-1 receptor agonist may be more appropriate for patients with coexisting diabetes or obesity, while resmetirom may be better suited for patients with more advanced liver disease or minimal metabolic comorbidities,” he said.
GLP-1 RAs, such as semaglutide, offer benefits for diabetes, obesity, and metabolic dysfunction in patients with MASLD/MASH and may be more accessible and cost effective, Ayesh told GI & Hepatology News. However, some patients may experience gastrointestinal side effects or be unable to tolerate GLP-1 RAs, he noted.
By contrast, resmetirom may be preferable for patients with low BMI, advanced fibrosis, or an inability to tolerate GLP-1s, as resmetirom directly targets hepatic pathways involved in MASLD/MASH progression, Ayesh said.
Next Steps to Inform Practice
“More research is needed to validate noninvasive biomarkers to monitor response to these medications, determine predictors of efficacy, and evaluate the additive effects, safety, and drug-drug interactions of combination therapy,” Lin said.
Studies are needed to determine both medications’ effects on patients with advanced fibrosis/cirrhosis and special populations, such as individuals with advanced renal disease or posttransplant patients, she added. More studies are expected to inform clinical practice and proper guidelines for the treatment of MASLD, as has been the case with chronic diseases such as hypertension and diabetes, Lin said.
Long-term safety and efficacy data are critical, as most trials of the newly approved medications have had relatively short follow-up periods of approximately 1 year, Ayesh said. “We need real-world evidence and longitudinal studies spanning 3-5 years to confirm sustained efficacy and safety,” he said. Research on cost effectiveness and health-system impacts will be essential to guide policy and ensure equitable access to the medications, he added.
The study by Lin and colleagues received no outside funding. The researchers had no financial conflicts to disclose. Ayesh had no financial conflicts to disclose.

Making Surgery Safer for Patients With Cirrhosis
, according to an updated guideline from the American College of Gastroenterology.
Procedures such as cholecystectomy and hernia repair can be safely performed if precautions are taken, but surgical decision-making in patients with cirrhosis calls for a nuanced approach that takes into account several factors, including severity of liver disease, nonhepatic comorbidities, and procedure-specific considerations, wrote lead author Nadim Mahmud, MD, assistant professor of medicine and epidemiology at the Perelman School of Medicine, University of Pennsylvania, Philadelphia, and colleagues, in the American Journal of Gastroenterology.
“Patients with cirrhosis face substantially higher risks from surgery than those without liver disease, and careful guidance and risk stratification are essential,” Mahmud told GI & Hepatology News.
“At the same time, more patients are living longer with cirrhosis and increasingly require nonhepatic surgeries. Clinicians need up-to-date, practical recommendations that go beyond liver scores alone by integrating liver disease severity, comorbidities, and procedure-specific risk,” Mahmud said. The new guideline provides a comprehensive framework to help ensure that patients with cirrhosis undergo necessary operations, while managing preventable complications, he explained.
The guideline includes four recommendations for preoperative care, of which three are conditional and one is strong. The strong recommendation calls for the use of thrombopoietin receptor agonists, dosed according to baseline platelet count, in patients with cirrhosis and severe thrombocytopenia who are undergoing invasive procedures to reduce the need for perioperative transfusions and potentially reduce the risk for periprocedural bleeding.
Three conditional recommendations:
- For patients with compensated cirrhosis and unclear presence of clinically significant portal hypertension (CSPH), preoperative liver stiffness measurement and platelet count assessment are recommended to determine whether CSPH is present due to increased perioperative risks associated with the condition. Cross-sectional imaging should be conducted to identify portosystemic collaterals and complications of portal hypertension.
- For patients with cirrhosis and CSPH with alternative indications for transjugular intrahepatic portosystemic shunt (TIPS), such as large varices or refractory ascites, preoperative TIPS is suggested to reduce postoperative morbidity and mortality attributable to portal hypertension.
- For patients with cirrhosis undergoing major hepatic surgery, referral to a high-volume liver surgery or transplant center, when feasible, is recommended.
The guideline also advises on 26 key concepts, including nutrition, alcohol and tobacco use, comorbidities such as frailty and sarcopenia, and preoperative treatment of liver disease drivers such as hepatitis B, hepatitis C, and autoimmune hepatitis.
What’s New and Notable?
New elements of the guideline include use of cirrhosis-specific risk calculators, especially the Veterans Outcomes and Costs Associated with Liver disease (VOCAL)-Penn Score, to estimate operative risk and facilitate shared decision-making regarding surgery. The VOCAL-Penn Score, developed by Mahmud and colleagues at the University of Pennsylvania, incorporates surgery type and has shown superiority to older tools that often overestimate risk, Mahmud told GI & Hepatology News.
The guideline highlights standardized assessment of portal hypertension using noninvasive liver stiffness measurement plus platelet count and imaging, Mahmud said. “The guideline also underscores the importance of considering liver transplant evaluation before surgery in higher-risk patients,” he noted.
Clinicians will find clear recommendations on optimizing the perioperative period through nutritional support and structured prehabilitation, as well as the use of viscoelastic testing to guide transfusion decisions and the use of thrombopoietin-receptor agonists for severe thrombocytopenia, he added.
“Importantly, in carefully selected patients with significant portal hypertension, a preoperative transjugular intrahepatic portosystemic shunt may be reasonable, though it is not recommended broadly,” Mahmud said. “Finally, procedure-specific guidance, such as elective hernia repair after ascites control, laparoscopic cholecystectomy in well-compensated cirrhosis, and sleeve gastrectomy as the bariatric procedure of choice, helps translate risk into action,” he said.
These elements address key challenges in managing perioperative risk in patients with cirrhosis, namely miscalibrated risk estimates, inconsistent portal hypertension assessment, hemostasis management, and wide variation in practice, Mahmud noted.
Tackling Clinical Challenges
The new guideline collates the latest evidence and assessment tools to provide practical advice for clinicians to not only estimate risk but also better prepare patients with cirrhosis for surgical procedures, Peter D. Block, MD, assistant professor of medicine in the section of digestive diseases at the Yale School of Medicine, New Haven, Connecticut, told GI & Hepatology News.
“The larger and more invasive the operation, the higher the risk,” said Block, who was not involved in writing the guideline. Surgeries associated with the highest risk for patients with cirrhosis include major open abdominal operations, chest or cardiothoracic surgery, and major vascular surgeries, as well as emergency operations, for which there is less time to optimize any liver-related problems in advance, he said.
“Cirrhosis affects clotting, fluid balance, immunity, kidney function, and medication clearance, and each of these factors influence surgical risk,” Block said. “The guideline recommends combining liver-specific risk assessment scores with surgery-specific factors and clinical judgement, rather than relying on a single test,” he noted.
For elective surgeries, “the guideline provides practical pathways for when and how to optimize first, and when surgery must proceed despite higher risk,” he said.
The guideline was supported by the American College of Gastroenterology. Mahmud disclosed receiving research support from the National Institute of Diabetes and Digestive and Kidney Diseases and investigator-initiated research funding from Grifols, unrelated to the guideline. Block had no financial conflicts to disclose.

Formula Type May Fuel NEC in Premature Infants
DENVER – , according to new data presented at the American Academy of Pediatrics (AAP) 2025 National Conference & Exhibition.
Necrotizing enterocolitis (NEC) can affect the intestinal wall of neonates, with potentially life-threatening results. The inflammatory condition is characterized by feeding intolerance, rectal bleeding, and bowel perforations, said presenting author Puja Kulkarni, medical student at California Northstate University College of Medicine, Elk Grove, California, and colleagues.
The etiology of NEC remains unclear, but previous research suggests that formula feeding may play a role, the researchers said. “NEC remains a leading cause of morbidity and mortality in premature infants, yet there is still no clear consensus on the optimal feeding strategy to reduce risk,” Kulkarni said in an interview with GI & Hepatology News.
Most hospital guidelines call for solely using SPFs in NICUs, especially in cases where maternal breast milk is not available, said Kulkarni. Therefore, “it was critical to investigate whether different types of formula, such as extensively hydrolyzed formula, could influence the incidence of NEC,” she said.
Kulkarni and colleagues conducted a literature search and identified three randomized, controlled trials that compared eHFs to SPFs in a study population of 1180 premature infants.
Overall, infants who received SPFs had a significantly greater risk for both NEC and feeding intolerance than those who received eHFs, with odds ratios of 2.54 and 2.87, respectively, and these associations remained after a sensitivity analysis.
Other research, such as the German Infant Nutritional Intervention (GINI) study, has shown similar results regarding the effect of formula type on childhood pathologies, Kulkarni noted. The GINI study showed that HFs can help prevent the development of allergic diseases in children with a family history of allergies, she said.
The results of the current analysis suggest a significantly increased risk for NEC, as well as feeding intolerance, which can be a precursor to NEC, in premature infants fed SPFs compared to those fed eHFs, said Kulkarni. “If validated by further research, this could lead to changes in NICU feeding protocols, especially in situations where donor breast milk is not available. Clinicians may want to consider the type of protein in formula as an important factor in NEC prevention,” she said. The current findings support the need for more research into the effects of formula throughout the infant and childhood years.
Additional studies are needed to validate the findings in larger, multicenter cohorts to ensure generalizability, especially in the US, where current guidelines favor SPFs based on limited data, said Kulkarni. Much of the research in the US has been conducted by the formula companies themselves, and she and her colleagues took this risk for bias into account in their meta-analysis.
Younger Babies at Greater Risk
Documented rates of NEC have remained stable or decreased slightly over the past 20 years, which supports the need for research on prevention and early identification, as well as effective medical treatment, said Catherine Haut, DNP, CPNP-AC/PC, in an interview.
“With improved neonatal intensive care, younger neonates are surviving, but these babies also have a higher risk of development of NEC,” said Haut, director of nursing research and evidence-based practice at Nemours Children’s Health, Delaware, New Jersey, who was not involved in the study.
“Historically, NEC has been related to feeding, among other variables, but the use of more specific or standardized feeding methods including increased use of human milk in very low-birth weight infants has resulted in better outcomes,” she said.
The finding from the current meta-analysis that the use of SPFs poses a higher risk for NEC than the use of eHFs was not unexpected, Haut told GI & Hepatology News. Some infants are allergic to cow’s milk, and replacing this type of formula with eHF is the recommended treatment as these formulas incorporate proteins which are more easily digested, she said.
Systematic reviews and meta-analyses are considered high levels of evidence, and the current study’s documentation of the benefits of eHF could help decrease the rate of NEC in premature infants, Haut said. “Despite a higher cost associated with eHF, in formula-fed preterm neonates, there would be benefit to using eHF vs risk of standard protein formulas,” she said.
However, the current study represents a very small population compared to the total number of infants born at less than 37 weeks’ gestation, which is reported to be 10% of all newborns in the US each year, Haut noted.
Additional large studies, including randomized control trials, are needed to further document the effects of using eHF in very young premature infants and potentially help reduce the incidence of NEC in this population, she said.
The study received no outside funding. The researchers and Haut had no financial conflicts to disclose.

Getting Ahead of Gastrointestinal Cancer
Early-onset gastrointestinal (GI) cancers are climbing among those younger than 50 years, in the US and globally. Although colorectal cancer accounts for approximately half of such cases, rates are also increasing for gastric, esophageal, pancreatic, and several rarer GI malignancies.
Because most in this age group are not included in screening protocols and may present with vague symptoms, diagnosis and treatment is frequently delayed. According to experts in the field, counteracting this trend requires establishing a lower threshold for evaluation, attention to modifiable risk factors, and embracing emerging noninvasive diagnostic tools.
Diagnostic Dilemmas
“Colorectal cancer in particular is often diagnosed later in life,” said Nicholas DeVito, MD, assistant professor at Duke University Medical Center, Durham, North Carolina, and a specialist in GI malignancies. “When the patient is too young for routine screening colonoscopy (< 45 years), they aren’t screened at all, they do not have alarming symptoms, or their symptoms are overlooked.” Other increasingly common GI cancers in young people (esophageal, gastric, pancreatic) lack routine screening guidelines due to limited evidence, he added.
Symptoms such as nausea, weight loss, upset stomach, and abdominal pain are often nonspecific and have many other potential causes, so GI cancers may not be high on the list of possible diagnoses in patients younger than 50 years, said DeVito.
“Insurance coverage, socioeconomic status, appointment availability, and awareness of symptoms and screening methods are all barriers to diagnosis as well, which affect the diagnostic timeline of many cancers,” he added.“While there are multiple factors that contribute to a cancer diagnosis, it seems that obesity, a Western diet, a sedentary lifestyle are all major contributors to the rise in early GI cancers,” DeVito told GI & Hepatology News. “There is no blame or judgement to go around as cancer can happen to anyone at any time, with none of these factors present,” he emphasized.
When counseling patients about GI cancer risk, DeVito recommends keeping advice simple and specific. In general, they should restrict red meat to once a week, emphasize fresh fruits and vegetables, cap alcohol to ≤ 1 serving per day, and limit ultraprocessed foods (e.g., packaged snacks, preprepared meals, and sugary beverages).
Exercise is another pillar. “Find an activity you enjoy and work toward 30 minutes of aerobic exercise three times a week,” he advised. He also encourages finding opportunities to incorporate physical activity in daily lives, such as using a standing desk at work, while keeping patients’ socioeconomic constraints in mind.
Evidence around GI cancer prevention interventions is still evolving. However, a randomized phase 3 trial presented at American Society of Clinical Oncology’s 2025 meeting found significant improvement in disease-free survival among adults with resected stage III or high-risk stage II colon cancer (median age, 61 years) who reported higher intake of anti-inflammatory foods and greater exercise than a comparator group.
“In general, clinicians should be aware of the risk factors, make referrals to physical therapy, weight-loss specialists, endocrinologists, and nutritionists when appropriate, and be consistent and clear with patients about recommendations and what’s achievable,” DeVito said. “Meeting patients where they are can help make incremental progress, as these interventions take time and patience, and we should be understanding of that.”
Identifying at-risk younger adults goes beyond discussing family history and obesity to include diet, exercise, and daily lifestyle, he added.
“Symptoms of potential GI cancer need to be taken seriously in all patients, and there should be a lower threshold in 2025 to get a colonoscopy, endoscopy, or CT scan than in previous years given all that we know today. We then need to establish through clinical studies who needs screening tests and who doesn’t, and what interventions work best to reduce risk.”
Vigilance in the Absence of Screening
“Most GI cancers, unfortunately, can grow a fair amount before symptoms arise, so many patients present with symptoms only when a tumor has grown enough to affect organ function,” said Miguel Burch, MD, chief of minimally invasive and GI surgery at Cedars-Sinai Medical Center, Los Angeles.
Early screening improves outcomes in gastric cancer, Burch noted, and survival benefits are reflected in several East Asian countries that offer gastric cancer screening starting at age 40. In one study from Korea, a single upper endoscopy was associated with an approximate 40% reduction in gastric cancer mortality compared with no screening.
, Burch emphasized. The impact is wide-ranging, contributing to increased morbidity and mortality in younger adults often in their most productive years, leading to lost wages and emotional strains upon patients and their families.Routine endoscopic or imaging screening is not typically performed in the US, and newer blood-based tests such as circulating tumor DNA are not yet sensitive enough to reliably detect very early-stage disease. Nonetheless, there is evidence that noninvasive biomarkers could soon help expand GI cancer screening.
In a study published in JAMA Surgery, Sui and colleagues tested a 10-microRNA signature assay (Destinex) for early detection of gastric cancer and reported robust identification rates above 95%.
“In recent years, the liquid biopsy has gained momentum with the hope of augmenting cancer detection from peripheral blood, even indicating potential as a screening test for healthy populations,” wrote Max R. Coffey, MD, and Vivian E. Strong, MD, both of the Memorial Sloan Kettering Cancer Center in New York City, in an accompanying editorial.
“Early detection is absolutely critical; when gastric cancer is found early, outcomes are dramatically better,” Strong told GI & Hepatology News. Subtle symptoms — reflux, persistent GI discomfort, or unexplained weight loss — should never be ignored, she added.
Early detection should also focus on additional risk factors such as prior Helicobacter pylori infection, smoking, and family history.
“Anyone with a personal or family history of H pylori should have very careful follow-up, and if one household member tests positive, all should be checked,” Strong said. “Just as importantly, if one or more family members have had stomach cancer, that should be discussed with a healthcare provider, as it may warrant higher-level surveillance and genetic testing.”
Individuals concerned about increased risk for GI cancer should proactively ask their doctors whether they might benefit from testing or surveillance, Strong added.
“Lifestyle changes, timely medical evaluation, and tailored surveillance all play a vital role in prevention.”
DeVito disclosed clinical trial funding from the Gateway foundation, Xilio, Phanes, Astellas, GSK, as well as consulting fees/advisory board participation for Guardant, Agenus, and Xilio. Strong disclosed speaking honoraria for Merck and Astra Zeneca.
The study by Sui and colleagues was supported by the National Cancer Institute, National Institutes of Health, as well as by a grant from the American Gastroenterological Association Robert & Sally Funderburg Research Award in Gastric Cancer, and the Stupid Strong Foundation.
Burch had no financial conflicts to disclose.

GI Disorders Linked With Sleep Problems
“Emerging evidence suggests a bidirectional relationship between GI diseases and sleep disorders, whereby dysfunction in one domain may exacerbate the other,” wrote Shicheng Ye, PhD, of The Third Clinical Medical College of Guangzhou University of Chinese Medicine, and colleagues. However, previous studies on the association between GI and sleep problems have been small, and the role of depression as a mediator has not been well explored.
In the study, which was published online in BMC Gastroenterology, the researchers reviewed data from the US National Health and Nutrition Examination Survey between 2005 and 2014. The study population included 10,626 adults aged 20 years or older, with a mean age of 45.6 years, 50.8% of whom were women. Of these, 6444 were identified as having GI disease on the basis of a “yes” response to the question of whether they had a stomach or intestinal illness with vomiting or diarrhea within the past 30 days.
Researchers also examined responses to survey questions related to sleep duration, trouble sleeping, and diagnosis of a sleep disorder. Individuals with vs without GI diseases had a significantly higher prevalence of sleep trouble (37.99% vs 24.21%; P < .001) and a greater frequency of diagnosed sleep disorders (14.99% vs 8.08%; P < .001).
An analysis adjusted for demographic, lifestyle, and clinical factors found that individuals with vs without GI diseases were 70% more likely to have sleep trouble. Individuals with vs without GI diseases were also significantly more likely to have a diagnosed sleep disorder and a reduction in sleep duration (adjusted odds ratio, 1.8; adjusted beta, -0.15).
The association between GI diseases and sleep problems remained consistent across individuals of multiple subgroups, including those without hypertension, diabetes, or a history of smoking. It also remained significant among individuals with coronary heart disease and higher scores on the dietary index for gut microbiota. No significant interaction effects related to age, sex, or chronic disease appeared in any subgroup (P > .05).
An additional mediation analysis found that depression partly mediated the associations between GI diseases and sleep issues. Depression accounted for 21.29% of the total effect on sleep problems, 19.23% of the effect on sleep disorders, and 26.68% of the effect on sleep duration.
The mediating role of depression on the association between GI disease and sleep problems may not be exclusive, the researchers wrote. Other potential mechanisms may include systemic inflammation, visceral hypersensitivity, and metabolic dysfunction.
The findings were limited by several factors, including the possibly underpowered sample size for machine-learning models and the reliance on self-reports of GI diseases, sleep outcomes, and coronary heart disease, the researchers noted. Other limitations included the inability to adjust for confounding factors, including obstructive sleep apnea, chronic pain, and hypertension.
However, the results illustrate the need to address both psychological and GI factors in clinical practice to improve sleep health, the researchers wrote. More research is needed to identify causal pathways and develop targeted, multidimensional interventions for this interconnected trio of health problems.
Increasing Evidence for Gut-Brain Interaction
Both sleep disorders and disorders of GBI (DGBI) are highly prevalent worldwide, Jatin Roper, MD, gastroenterologist and associate professor of medicine at Duke University, Durham, North Carolina, told GI & Hepatology News.
“A growing body of evidence suggests that DGBI, including irritable bowel syndrome, are caused by imbalances in signaling between the brain and the intestine, which include the vagus nerve, hormonal signals, the gut microbiota, and immune system,” said Roper, who was not involved in the current study.
“Since many sleep disturbances are centrally mediated, it is plausible that sleep and gastrointestinal disorders could be mechanistically linked,” he said. Rigorous analysis of patient databases for a possible association between sleep and GI disorders, as was done in the current study, is an important step.
The current study findings were not unexpected, “particularly the finding that depression may mediate a link between sleep and GI disorders, because depression is well known to be associated to sleep disturbances and DGBI,” Roper said.
However, GI doctors often do not ask patients about problems with sleep, and pulmonary doctors or sleep specialists may not ask patients about GI symptoms, Roper noted. Similarly, patients may not bring up all their symptoms when seeing these specialists.
“The current study underscores the need for comprehensive, multisystem evaluations in specialty clinics for sleep and GI conditions and appropriate referrals to specialists, when necessary,” he said.
The research raised an important question of whether sleep and GI disorders are associated with each other because of other underlying medical conditions, which may be difficult to control for in cross-sectional studies, or whether sleep problems cause GI problems or vice versa, Roper said. Other uncertainties include whether the conditions are biologically linked, possibly through shared changes in the brain-gut axis.
Long-term observational studies would be useful to identify whether sleep disturbances precede DGBI or vice versa, Roper added.
The study received no outside funding. The researchers and Roper had no financial conflicts to disclose.

“Emerging evidence suggests a bidirectional relationship between GI diseases and sleep disorders, whereby dysfunction in one domain may exacerbate the other,” wrote Shicheng Ye, PhD, of The Third Clinical Medical College of Guangzhou University of Chinese Medicine, and colleagues. However, previous studies on the association between GI and sleep problems have been small, and the role of depression as a mediator has not been well explored.
In the study, which was published online in BMC Gastroenterology, the researchers reviewed data from the US National Health and Nutrition Examination Survey between 2005 and 2014. The study population included 10,626 adults aged 20 years or older, with a mean age of 45.6 years, 50.8% of whom were women. Of these, 6444 were identified as having GI disease on the basis of a “yes” response to the question of whether they had a stomach or intestinal illness with vomiting or diarrhea within the past 30 days.
Researchers also examined responses to survey questions related to sleep duration, trouble sleeping, and diagnosis of a sleep disorder. Individuals with vs without GI diseases had a significantly higher prevalence of sleep trouble (37.99% vs 24.21%; P < .001) and a greater frequency of diagnosed sleep disorders (14.99% vs 8.08%; P < .001).
An analysis adjusted for demographic, lifestyle, and clinical factors found that individuals with vs without GI diseases were 70% more likely to have sleep trouble. Individuals with vs without GI diseases were also significantly more likely to have a diagnosed sleep disorder and a reduction in sleep duration (adjusted odds ratio, 1.8; adjusted beta, -0.15).
The association between GI diseases and sleep problems remained consistent across individuals of multiple subgroups, including those without hypertension, diabetes, or a history of smoking. It also remained significant among individuals with coronary heart disease and higher scores on the dietary index for gut microbiota. No significant interaction effects related to age, sex, or chronic disease appeared in any subgroup (P > .05).

Federal Government Funds Program for Hepatitis C Care and Cure
, according to an HHS press release.
The program, known as the Hepatitis C Elimination Initiative Pilot, will be administered by the Substance and Mental Health Administration. “This program is designed to support communities severely affected by homelessness and to gain insights on effective ways to identify patients, complete treatment, cure infections, and reduce reinfection by hepatitis C,” according to the press release.
The upfront investment in hepatitis C management is projected to not only save lives, but also to save community health care costs in the long-term, according to the press release.
“This is a vigorous pilot program that provides the first steps toward the large goal of eliminating hepatitis C in the United States population,” said William Schaffner, MD, professor of infectious diseases at Vanderbilt University Medical Center, Nashville, Tennessee, in an interview.
Hepatitis C affects more than two million individuals in the US, and is often complicated by social and medical issues such as homelessness, substance abuse, and mental health issues, said Schaffner. Fortunately, hepatitis C can be treated with oral medications that cure the chronic viral infection, thereby ending ongoing liver injury and interrupting person-to-person transmission of the virus by sharing needles, he said.
Given that the population most affected with hepatitis C also is often homeless, with possible mental health issues and sharing of needles for illicit drug use, challenges in reaching this population include assuring them that the care they receive though this and other programs is nonjudgemental and helpful, Schaffner told GI & Hepatology News.
The oral medications that now can cure the chronic hepatitis C viral infections must be taken over a period of weeks, and patients who lead socially disorganized lives often need assistance to assure that the medicine is taken as intended, so trained and sensitive personnel who are committed to helping this population are needed to make treatment programs succeed, he said.
Looking ahead, “the purpose of the pilot studies that will be funded by this program is to explore various approaches to determine which are more successful in bringing patients in to be evaluated and then to complete treatment,” Schaffner added.
State and community-based organizations are among the entities eligible to apply for the program. Potential applicants can find information about the program and application materials on the SAMSHA website.
Schaffner had no financial conflicts to disclose.

Novel Peptides Expressed in HIV Could Drive Treatment
Genetic sequencing of peptides in rebound virus in individuals with HIV who had analytic treatment interruptions (ATIs) confirmed the peptides’ expression in HIV-1 infection, according to data presented at the International AIDS Society Conference on HIV Science.
Previous research has shown that HIV-specific CD8 T-cell responses directed against five genetically conserved HIV-1 protein regions (Gag, Pol, Vif, Vpr, and Env) are associated with viral control, Josefina Marín-Rojas, PhD, Faculty of Medicine and Health, University of Sydney, and colleagues wrote in their abstract.
However, data on whether these peptides are expressed in rebound virus among individuals with HIV who experienced ATI are limited, they wrote.
The researchers applied an immunoinformatics analysis pipeline (IMAP) to select 182 peptides (IMAP-peptides) from structurally important and mutation-intolerant regions of HIV-1 proteins, senior author Sarah Palmer, PhD, co-director of the Centre for Virus Research at the Westmead Institute for Medical Research and professor in the Faculty of Medicine and Health at the University of Sydney, said in an interview.
“Our studies indicate if the immune system targets these structurally important and mutation-intolerant regions of HIV-1 proteins, this can contribute to virological control in the absence of HIV-1 therapy,” she explained.
The researchers reviewed data from the PULSE clinical trial, which included 68 men who have sex with men living with HIV in Australia. The men underwent three consecutive ATIs. A total of seven participants’ transiently controlled HIV rebound during the third ATI. The researchers examined whether the IMAP peptides were present in the HIV-1 RNA sequences of the rebound virus in four noncontrollers (patients who had viral rebound in all three ATIs) and five of the seven transient controllers who showed viral control during the third ATI.
The technique of near full-length HIV-1 RNA sequencing of rebound virus from three noncontrollers and two transient controllers identified the Gag, Pol, Vif, Vpr, and Env IMAP-peptides in 52%-100% of the viral sequences obtained from these participants across three ATI timepoints.
“We assumed that cells from people living with HIV that experience virological control after treatment interruption would have the immune response to our IMAP-peptides that we observed; however, we are amazed and encouraged by the level and extent of this immune response,” Palmer told this news organization.
The researchers also compared CD8 T-cell response between the IMAP peptides and a control peptide pool without the IMAP peptides.
The CD8 T-cells from three transient controllers had a 15- to 53-fold higher effector response to the IMAP-peptides than the CD8 T-cells from two noncontrollers, the researchers wrote in their abstract. The relative response to the IMAP-peptides in noncontrollers was 20 times lower than that to the control peptides, but the IMAP-peptide response in the transient controllers group was similar to that in the control group, the authors noted.
The results highlight the potential of IMAP in developing treatment strategies. Although the results are too preliminary to impact clinical practice at this time, the findings from the current study could lead to the development of an mRNA vaccine to clear HIV-infected cells from people living with HIV, Palmer told this news organization.
“Our next steps include developing and testing mRNA vaccine constructs that contain our IMAP-peptides to assess the immune response of cells from people living with HIV to these vaccines,” Palmer said. “From there we will conduct studies of the most promising mRNA vaccine constructs in a humanized mouse model,” she said.
Data Enhance Understanding of Immunity
The current study may provide information that can significantly impact understanding of the immune responses to HIV, David J. Cennimo, MD, associate professor of medicine and pediatrics in the Division of Infectious Disease at Rutgers New Jersey Medical School, Newark, New Jersey, said in an interview.
“The investigators looked at highly conserved regions of multiple HIV proteins,” said Cennimo, who was not involved in the study. “Conserved regions and antibody responses to them may play a role in controlling HIV viral replication and rebound,” Cennimo told this news organization. “The investigators showed these regions were present in rebounding viremia, and individuals that exhibited greater immune recognition of these regions suppressed rebound viremia longer, and perhaps targeting these regions could impact HIV prevention or cure strategies,” he said.
Secondarily, the study showed the success of the novel technique (IMAP) to identify conserved peptides, said Cennimo. The technique could potentially be applied to other viruses that mutate to escape host response, he said.The study was funded by the U.S. National Institutes of Health, the Foundation for AIDS Research, the Australian National Health and Medical Research Council, and Sandra and David Ansley. The researchers and Cennimo disclosed no financial conflicts of interest.

Stay Alert to Sleep Apnea Burden in the Military
Obstructive sleep apnea (OSA) was associated with a significantly increased risk for adverse health outcomes and health care resource use among military personnel in the US, according to data from about 120,000 active-duty service members.
OSA and other clinical sleep disorders are common among military personnel, driven in part by demanding, nontraditional work schedules that can exacerbate sleep problems, but OSA’s impact in this population has not been well-studied, Emerson M. Wickwire, PhD, of the University of Maryland School of Medicine, Baltimore, and colleagues wrote in a new paper published in Chest.
In the current health economic climate of increasing costs and limited resources, the economic aspects of sleep disorders have never been more important, Wickwire said in an interview. The data in this study are the first to quantify the health and utilization burden of OSA in the US military and can support military decision-makers regarding allocation of scarce resources, he said.
To assess the burden of OSA in the military, they reviewed fully de-identified data from 59,203 active-duty military personnel with diagnoses of OSA and compared them with 59,203 active-duty military personnel without OSA. The participants ranged in age from 18 to 64 years; 7.4% were women and 64.5% were white individuals. Study outcomes included new diagnoses of physical and psychological health conditions, as well as health care resource use in the first year after the index date.
About one third of the participants were in the Army (38.7%), 25.6% were in the Air Force, 23.5% were in the Navy, 5.8% were in the Marines, 5.7% were in the Coast Guard, and 0.7% were in the Public Health Service.
Over the 1-year study period, military personnel with OSA diagnoses were significantly more likely to experience new physical and psychological adverse events than control individuals without OSA, based on proportional hazards models. The physical conditions with the greatest increased risk in the OSA group were traumatic brain injury and cardiovascular disease (which included acute myocardial infarction, atrial fibrillation, ischemic heart disease, and peripheral procedures), with hazard ratios (HRs) 3.27 and 2.32, respectively. The psychological conditions with the greatest increased risk in the OSA group vs control individuals were posttraumatic stress disorder (PTSD) and anxiety (HR, 4.41, and HR, 3.35, respectively).
Individuals with OSA also showed increased use of healthcare resources compared with control individuals without OSA, with an additional 170,511 outpatient visits, 66 inpatient visits, and 1,852 emergency department visits.
Don’t Discount OSA in Military Personnel
“From a clinical perspective, these findings underscore the importance of recognizing OSA as a critical risk factor for a wide array of physical and psychological health outcomes,” the researchers wrote in their discussion.
The results highlight the need for more clinical attention to patient screening, triage, and delivery of care, but efforts are limited by the documented shortage of sleep specialists in the military health system, they noted.
Key limitations of the study include the use of an administrative claims data source, which did not include clinical information such as disease severity or daytime symptoms, and the nonrandomized, observational study design, Wickwire told this news organization.
Looking ahead, the researchers at the University of Maryland School of Medicine and the Uniformed Services University, Bethesda, Maryland, are launching a new trial to assess the clinical effectiveness and cost-effectiveness of telehealth visits for military beneficiaries diagnosed with OSA as a way to manage the shortage of sleep specialists in the military health system, according to a press release from the University of Maryland.
“Although the association between poor sleep and traumatic stress is well-known, present results highlight striking associations between sleep apnea and posttraumatic stress disorder, traumatic brain injury, and musculoskeletal injuries, which are key outcomes from the military perspective,” Wickwire told this news organization.
“Our most important clinical recommendation is for healthcare providers to be on alert for signs and symptoms of OSA, including snoring, daytime sleepiness, and morning dry mouth,” said Wickwire. “Primary care and mental health providers should be especially attuned,” he added.
Results Not Surprising, but Research Gaps Remain
“The sleep health of active-duty military personnel is not only vital for optimal military performance but also impacts the health of Veterans after separation from the military,” said Q. Afifa Shamim-Uzzaman, MD, an associate professor and a sleep medicine specialist at the University of Michigan, Ann Arbor, Michigan, in an interview.
The current study identifies increased utilization of healthcare resources by active-duty personnel with sleep apnea, and outcomes were not surprising, said Shamim-Uzzaman, who is employed by the Veterans’ Health Administration, but was not involved in the current study.
The association between untreated OSA and medical and psychological comorbidities such as cardiovascular disease, diabetes, and mood disorders such as depression and anxiety is well-known, Shamim-Uzzaman said. “Patients with depression who also have sleep disturbances are at higher risk for suicide — the strength of this association is such that it led the Veterans’ Health Administration to mandate suicide screening for Veterans seen in its sleep clinics,” he added.
“We also know that untreated OSA is associated with excessive daytime sleepiness, slowed reaction times, and increased risk of motor vehicle accidents, all of which can contribute to sustaining injuries such as traumatic brain injury,” said Shamim-Uzzaman. “Emerging evidence also suggests that sleep disruption prior to exposure to trauma increases the risk of developing PTSD. Therefore, it is not surprising that patients with sleep apnea would have higher healthcare utilization for non-OSA conditions than those without sleep apnea,” he noted.
In clinical practice, the study underscores the importance of identifying and managing sleep health in military personnel, who frequently work nontraditional schedules with long, sustained shifts in grueling conditions not conducive to healthy sleep, Shamim-Uzzaman told this news organization. “Although the harsh work environments that our active-duty military endure come part and parcel with the job, clinicians caring for these individuals should ask specifically about their sleep and working schedules to optimize sleep as best as possible; this should include, but not be limited to, screening and testing for sleep disordered breathing and insomnia,” he said.
The current study has several limitations, including the inability to control for smoking or alcohol use, which are common in military personnel and associated with increased morbidity, said Shamim-Uzzaman. The study also did not assess the impact of other confounding factors, such as sleep duration and daytime sleepiness, that could impact the results, especially the association of OSA and traumatic brain injury, he noted. “More research is needed to assess the impact of these factors as well as the effect of treatment of OSA on comorbidities and healthcare utilization,” he said.

Obstructive sleep apnea (OSA) was associated with a significantly increased risk for adverse health outcomes and health care resource use among military personnel in the US, according to data from about 120,000 active-duty service members.
OSA and other clinical sleep disorders are common among military personnel, driven in part by demanding, nontraditional work schedules that can exacerbate sleep problems, but OSA’s impact in this population has not been well-studied, Emerson M. Wickwire, PhD, of the University of Maryland School of Medicine, Baltimore, and colleagues wrote in a new paper published in Chest.
In the current health economic climate of increasing costs and limited resources, the economic aspects of sleep disorders have never been more important, Wickwire said in an interview. The data in this study are the first to quantify the health and utilization burden of OSA in the US military and can support military decision-makers regarding allocation of scarce resources, he said.
To assess the burden of OSA in the military, they reviewed fully de-identified data from 59,203 active-duty military personnel with diagnoses of OSA and compared them with 59,203 active-duty military personnel without OSA. The participants ranged in age from 18 to 64 years; 7.4% were women and 64.5% were white individuals. Study outcomes included new diagnoses of physical and psychological health conditions, as well as health care resource use in the first year after the index date.
About one third of the participants were in the Army (38.7%), 25.6% were in the Air Force, 23.5% were in the Navy, 5.8% were in the Marines, 5.7% were in the Coast Guard, and 0.7% were in the Public Health Service.
Over the 1-year study period, military personnel with OSA diagnoses were significantly more likely to experience new physical and psychological adverse events than control individuals without OSA, based on proportional hazards models. The physical conditions with the greatest increased risk in the OSA group were traumatic brain injury and cardiovascular disease (which included acute myocardial infarction, atrial fibrillation, ischemic heart disease, and peripheral procedures), with hazard ratios (HRs) 3.27 and 2.32, respectively. The psychological conditions with the greatest increased risk in the OSA group vs control individuals were posttraumatic stress disorder (PTSD) and anxiety (HR, 4.41, and HR, 3.35, respectively).

Experts Recommend Medication for Pediatric MASLD Management
, according to a new joint perspective paper.
Pediatric MASLD is the number-one cause of chronic liver disease in children and the number-one reason for liver transplant listing in young adults aged 18-40 years, said corresponding author Jennifer A. Panganiban, MD, Children’s Hospital of Philadelphia, Philadelphia.
The paper, published in Obesity Pillars, represents “a call to action that has been long overdue,” Panganiban told GI & Hepatology News.
The goal of the authors was to bring global awareness to the recent changes in the pediatric MASLD landscape — especially in medication use — and to empower clinicians treating the disease, she explained.
The recommendations are based on a combination of the latest published evidence and clinical expertise from eight hepatologists/gastroenterologists and two physicians from the Obesity Medicine Association, Centennial, Colorado.
One of the major barriers to MASLD management in children is suboptimal screening resulting in underdiagnosis, said Panganiban. “Unfortunately, only up to 30% of children are being screened in their pediatrician’s office.”
The new guideline outlines the patient care process from screening, referral to a subspecialist, and workup; however, the primary focus is on treatment with medication options that were previously not available or underutilized, she said.
Successful and Sustainable Weight Loss
Adiposity and weight gain make MASLD worse, but weight reduction has been shown to improve the condition, the authors noted. Previous strategies for curbing MASLD in children with obesity have focused mainly on lifestyle changes, but with limited success.
Nevertheless, the authors recommend continuing physical activity and nutrition as treatments for MASLD in children, with a plan tailored specifically to the patient.
In addition, however, they suggest that anti-obesity medications started early in the disease may help reduce costs and improve future outcomes.
Although glucagon-like peptide 1 receptor agonists (GLP-1 RAs) have not yet been studied specifically for pediatric MASLD, data from studies of pediatric obesity, diabetes, and other retrospective studies are encouraging, the authors wrote.
The GLP-1 RAs liraglutide and semaglutide are both approved by the US Food and Drug Administration (FDA) for managing obesity in children and adolescents aged 12 years or older, they noted. And a recent phase 3a randomized trial showed that liraglutide, not yet approved for children younger than 12 years, led to a mean change in body mass index of 5.8% from baseline to 56 weeks in children aged 6-11 years with obesity.
GLP-1 RAs not only are effective for weight management but also improve other metabolic dysfunction indicators including cholesterol and blood pressure, which makes these medications an even more beneficial option for individuals with obesity and MASLD, Panganiban and colleagues wrote.
For example, a recent single-center study of 111 children with MASLD (mean age, 15 years) showed a significant improvement in alanine aminotransferase levels with the use of GLP-1 RAs, although body mass index and weight were unchanged.
Regaining weight after discontinuing GLP-1 RAs is the main barrier to their use for MASLD, the authors noted. In addition, GLP-1 RAs are contraindicated in some situations, such as in those with a history of serious hypersensitivity, and in patients with a personal or family history of either medullary thyroid carcinoma or multiple endocrine neoplasia syndrome type 2 based on animal studies showing an association with the medications and thyroid C–cell tumors.
Other FDA-approved medication options for obesity in children include metformin, topiramate, and phentermine, as well as bupropion, lisdexamfetamine, and setmelanotide, the authors said.
Resmetirom, a thyroid hormone receptor-beta agonist, which is another significant breakthrough in MASLD for adults, has not yet been tested or approved for pediatric use.
In addition to medications, metabolic bariatric surgery has shown effectiveness in children with obesity and/or MASLD by reducing liver fat and reversing fibrosis, as shown in the Teen-LABS study, the authors wrote. However, long-term data on fibrosis reversal are limited, and cost and access remain barriers.
More Research Needed
The joint expert review is intended as an educational tool that may require updates and should not be interpreted as rules for individual patient care, the authors cautioned. And physical activity and nutrition remain the primary treatment of MASLD and should be continued in conjunction with other treatment modalities, they emphasized.
Looking ahead, research is needed to develop accurate and reliable noninvasive biomarkers to diagnose and assess obesity treatment efficacy, Panganiban told GI & Hepatology News.
Also needed are multicenter randomized control trials in children with obesity involving different medications that have been successful in the treatment of metabolic dysfunction–associated steatohepatitis/fibrosis in adults, such as GLP-1 RAs or resmetirom, she added.
Educating Clinicians on Early Identification
When obesity occurs in childhood, it starts a process of additional complications that arise in earlier ages in adults, said Saul J. Karpen, MD, chief scientific officer at the Stravitz-Sanyal Institute for Liver Disease and Metabolic Health, Virginia Commonwealth University, Richmond, Virginia, in an interview.“Given the epidemic of obesity, altered diets, and reduced physical activities during younger ages, it is not easy to identify which children are at greater risk of MASLD,” said Karpen.
“It requires insight from the care providers and often imaging, a blood test, or a referral to a pediatric hepatologist, and not every region has easy access to such expertise,” Karpen said.
The new review is important because it highlights the fact that obesity and its consequences are not limited to adulthood, and that educated clinicians are in a position to get an early start on treatment in children, Karpen noted.
The guideline received no outside funding. Panganiban and Karpen had no financial conflicts to disclose.

When obesity occurs in childhood, it starts a process of additional complications that arise in earlier ages in adults, said Saul J. Karpen, MD, chief scientific officer at the Stravitz-Sanyal Institute for Liver Disease and Metabolic Health, Virginia Commonwealth University, Richmond, Virginia, in an interview.“Given the epidemic of obesity, altered diets, and reduced physical activities during younger ages, it is not easy to identify which children are at greater risk of MASLD,” said Karpen.
“It requires insight from the care providers and often imaging, a blood test, or a referral to a pediatric hepatologist, and not every region has easy access to such expertise,” Karpen said.
The new review is important because it highlights the fact that obesity and its consequences are not limited to adulthood, and that educated clinicians are in a position to get an early start on treatment in children, Karpen noted.
The guideline received no outside funding. Panganiban and Karpen had no financial conflicts to disclose.

Elemental Diet Eases Symptoms in Microbiome Gastro Disorders
, according to a new study.
“Elemental diets have long shown promise for treating gastrointestinal disorders like Crohn’s disease, eosinophilic esophagitis, SIBO (small intestinal bacterial overgrowth), and IMO (intestinal methanogen overgrowth), but poor palatability has limited their use,” lead author Ali Rezaie, MD, medical director of the Gastrointestinal (GI) Motility Program and director of Bioinformatics at Cedars-Sinai Medical Center, Los Angeles, told GI & Hepatology News.
Elemental diets are specialized formulas tailored to meet an individual’s specific nutritional needs and daily requirements for vitamins, minerals, fat, free amino acids, and carbohydrates.
In SIBO and IMO specifically, only about half the patients respond to antibiotics, and many require repeat treatments, which underscores the need for effective nonantibiotic alternatives, said Rezaie. “This is the first prospective trial using a PED, aiming to make this approach both viable and accessible for patients,” he noted.
Assessing a Novel Diet in IMO and SIBO
In the study, which was recently published in Clinical Gastroenterology and Hepatology, Rezaie and colleagues enrolled 30 adults with IMO (40%), SIBO (20%), or both (40%). The mean participant age was 45 years, and 63% were women.
All participants completed 2 weeks of a PED, transitioned to 2-3 days of a bland diet, and then resumed their regular diets for 2 weeks.
The diet consisted of multiple 300-calorie packets, adjusted for individual caloric needs. Participants could consume additional packets for hunger but were prohibited from eating other foods. There was no restriction on water intake.
The primary endpoint was changes in stool microbiome after the PED and reintroduction of regular food. Secondary endpoints included lactose breath test normalization to determine bacterial overgrowth in the gut, symptom response, and adverse events.
Researchers collected 29 stool samples at baseline, 27 post-PED, and 27 at study conclusion (2 weeks post-diet).
Key Outcomes
Although the stool samples’ alpha diversity decreased after the PED, the difference was not statistically significant at the end of the study. However, 30 bacterial families showed significant differences in relative abundance post-PED.
Daily symptom severity improved significantly during the second week of the diet compared with baseline, with reduction in abdominal discomfort, bloating, distention, constipation, and flatulence. Further significant improvements in measures such as abdominal pain, diarrhea, fatigue, urgency, and brain fog were observed after reintroducing regular food.
“We observed 73% breath test normalization and 83% global symptom relief — with 100% adherence and tolerance to 2 weeks of exclusive PED,” Rezaie told GI & Hepatology News. No serious adverse events occurred during the study, he added.
Lactose breath test normalization rates post-PED were 58% in patients with IMO, 100% in patients with SIBO, and 75% in those with both conditions.
The extent of patient response to PED was notable, given that 83% had failed prior treatments, Rezaie said.
“While we expected benefit based on palatability improvements and prior retrospective data, the rapid reduction in methane and hydrogen gas — and the sustained microbiome modulation even after reintroducing a regular diet — exceeded expectations,” he said. A significant reduction in visceral fat was another novel finding.
“This study reinforces the power of diet as a therapeutic tool,” Rezaie said, adding that the results show that elemental diets can be palatable, thereby improving patient adherence, tolerance, and, eventually, effectiveness. This is particularly valuable for patients with SIBO and IMO who do not tolerate or respond to antibiotics, prefer nonpharmacologic options, or experience recurrent symptoms after antibiotic treatment.
Limitations and Next Steps
Study limitations included the lack of a placebo group with a sham diet, the short follow-up after reintroducing a regular diet, and the inability to assess microbial gene function.
However, the results support the safety, tolerance, and benefit of a PED in patients with IMO/SIBO. Personalized dietary interventions that support the growth of beneficial bacteria may be an effective approach to treating these disorders, Rezaie and colleagues noted in their publication.
Although the current study is a promising first step, longer-term studies are needed to evaluate the durability of microbiome and symptom improvements, Rezaie said.
Making the Most of Microbiome Manipulation
Elemental diets may help modulate the gut microbiome while reducing immune activation, making them attractive for microbiome-targeted gastrointestinal therapies, Jatin Roper, MD, a gastroenterologist at Duke University, Durham, North Carolina, told GI & Hepatology News.
“Antibiotics are only effective in half of SIBO cases and often require retreatment, so better therapies are needed,” said Roper, who was not affiliated with the study. He added that its findings confirmed the researchers’ hypothesis that a PED can be both safe and effective in patients with SIBO.
Roper noted the 83% symptom improvement as the study’s most unexpected and encouraging finding, as it represents a substantial improvement compared with standard antibiotic therapy. “It is also surprising that the tolerance rate of the elemental diet in this study was 100%,” he said.
However, diet palatability remains a major barrier in real-world practice.
“Adherence rates are likely to be far lower than in trials in which patients are closely monitored, and this challenge will not be easily overcome,” he added.
The study’s limitations, including the lack of metagenomic analysis and a placebo group, are important to address in future research, Roper said. In particular, controlled trials of elemental diets are needed to determine whether microbiome changes are directly responsible for symptom improvement.
The study was supported in part by Good LFE and the John and Geraldine Cusenza Foundation. Rezaie disclosed serving as a consultant/speaker for Bausch Health and having equity in Dieta Health, Gemelli Biotech, and Good LFE. Roper had no financial conflicts to disclose.
