Liver Disease

WASHINGTON – Women with autoimmune liver diseases (AILD) may face increased risks for major adverse cardiovascular outcomes, according to a study presented at the annual Digestive Disease Week^® (DDW).

In particular, women with autoimmune hepatitis (AIH) and primary biliary cholangitis (PBC) appear to have higher risks than women without AIH or PBC. Those with primary sclerosing cholangitis (PSC) don’t seem to have increased risks.

“We know that cardiovascular disease remains the number one cause of death, but the mortality rate for women over the last decade has plateaued, whereas in men it’s actually declining due to interventions,” said lead author Rachel Redfield, MD, a transplant hepatology fellow at Thomas Jefferson University Hospital in Philadelphia.

“This is likely because we don’t have adequate risk stratification, especially for women,” she said. “We know that immune-mediated diseases — such as rheumatoid arthritis and psoriasis — carry a higher risk of cardiovascular disease, but there’s not a lot of data on our autoimmune liver disease patients.”

Although being a female can offer protection against some CVD risks, the atherosclerotic cardiovascular disease (ASCVD) 10-year risk score calculator recommended by the American College of Cardiology doesn’t include chronic inflammatory diseases associated with increased CVD risk, including AILD.

Dr. Redfield and colleagues conducted a multicenter, retrospective cohort study of patients with AIH, PBC, and PSC from 1999-2019. Using TriNetX data, the researchers looked at women with AILD who also had diabetes mellitus, hypertension, and hyperlipidemia, as well as a control group of men and women with these same disorders, excluding those who used biologics, immune modulators, and steroids or had other autoimmune disorders.

The research team used 1:1 propensity-score matching for women in the study group and in the control group based on age, race, ethnicity, ASCVD risk factors, and tobacco use. Women in the study group and men in the control group were matched for age, race, ethnicity, and tobacco use.

The primary outcome was summative cardiovascular risk, including unstable angina, acute myocardial infarction, presence of coronary angioplasty implant, coronary artery bypass, percutaneous coronary intervention, and cerebral infarction.

Overall, women with AIH had a significantly higher cardiovascular risk compared to women without AIH, at 25.4% versus 20.6% (P = .0007).

Specifically, women with PBC had a significantly higher cardiovascular risk compared to women without PBC, at 27.05% versus 20.9% (P < .0001).

There wasn’t a significant difference in risk between women with and without PSC, at 27.5% versus 21.8% (P = .27).

When compared to men without disease, women with AIH didn’t have a statistically significant higher risk, at 25.3% versus 24.2% (P = .44). Similarly, there didn’t appear to be a significant difference between women with PBC and men without PBC, at 26.9% versus 25.9% (P = .52), or between women with PSC and men without PSC, at 27.7% versus 26.2% (P = .78).

Dr. Redfield and colleagues then compared the ASCVD-calculated risk versus database risk, finding that in each group of women with AILD — including AIH, PBC, and PSC — the ASCVD-calculated risk was around 11%, compared with database risk scores of 25% for AIH, 27% for PBC, and 28% for PSC. These database risks appeared similar to both the ASCVD and database risk percentages for men.

“So potentially there’s an oversight in women with any kind of inflammatory disease, but specifically here, autoimmune liver diseases,” she said. “We really need to enhance our risk assessment strategies to take into account their risk and optimize patient outcomes.”

Dr. Redfield noted the limitations with using TriNetX data, including coding consistency among providers and healthcare organizations, unknown patient follow-up dates, and the inability to capture various inflammatory disease phenotypes, such as autoimmune hepatitis with multiple flares, which may be associated with higher cardiovascular risks.

As an attendee of the DDW session, Kenneth Kelson, MD, a gastroenterologist with Fremont Medical Group and Washington Hospital Healthcare System in Fremont, California, noted the importance of investigating the effects of different types of statins in these patients. Although the research team looked at top-level differences among statin users, finding that women with AILD were more likely to be on a statin, they didn’t incorporate statin therapy in the propensity-score matching model.

“Lipid-soluble statins are known to cause more liver trouble, even though it’s pretty low,” Dr. Kelson said. “Whereas the water-soluble statins have a lower incidence of liver issues.”

Dr. Redfield and Dr. Kelson reported no relevant disclosures.

TOPLINE: 

The intelligent Liver Function Testing (iLFT) platform can improve diagnosis and management of chronic liver disease in a primary care setting, new data show. 

METHODOLOGY:

• At the European Association for the Study of the Liver (EASL) Congress 2024, researchers presented 5-year, real-world data of the iLFT platform from its use in NHS Tayside in Dundee, Scotland, which serves a population of 400,000. The platform has been available since 2018.
• The iLFT platform uses an automated algorithm that analyzes standard liver function test results.
• Abnormal results prompt the system to initiate further fibrosis scoring and relevant etiologic testing to determine the cause of liver dysfunction.
• The results of these tests combined with practitioner-entered clinical information produce a probable diagnosis and recommend a patient-management strategy.

TAKEAWAY: 

• Of the 26,459 iLFT tests performed between 2018 and 2023, 68.3% (18,079) required further testing beyond the initial liver function test, whereas 31.7% (8380) did not.
• Further testing generated 20,895 outcomes, of which, isolated abnormal alanine transaminase (ALT) without fibrosis was most frequent (23.7%). Abnormal ALT was found to be most likely due to metabolic dysfunction–associated steatotic liver disease (MASLD).
• Overall, half of cascaded samples had a positive etiologic diagnosis. Alcoholic liver disease (ALD) and MASLD were the most common etiologic outcomes identified.
• In addition, 20% of cascaded tests identified potentially significant liver fibrosis.
• A total of 69.9% of outcomes recommended that patients could be safely managed in primary care. The inclusion of automatic Enhanced Liver Fibrosis (ELF) testing in 2020 further reduced the requirement for referral to secondary care by 34%.

IN PRACTICE:

“Without this algorithm, the 18,000 patients who had algorithm-directed further testing would have had to go back to the [primary care practitioner] to obtain the additional tests, and the [primary care practitioner] would need to interpret them too,” said Damien Leith, MD, trainee hepatologist at Ninewells Hospital, Dundee, Scotland, who presented the findings. “iLFTs ensure the right patients get automated, appropriate follow-up testing and subsequent recommendation of referral to secondary care if necessary, and importantly iLFT helps the primary care practitioner identify the cause of chronic liver disease.” 

SOURCE:

This study was presented on June 6, 2024 at the EASL Congress 2024 (abstract OS-007-YI).

LIMITATIONS:

Limitations include the need for further refinement of the algorithm to increase the proportion of positive etiologic iLFT outcomes. More analysis is needed to optimize the cost-effectiveness of iLFT. 

DISCLOSURES:

Dr. Leith reports no relevant financial relationships.

The US Food and Drug Administration (FDA) has granted accelerated approval for Iqirvo (elafibranor; Ipsen) for treatment of primary biliary cholangitis (PBC) in combination with ursodeoxycholic acid (UDCA) in adults who do not respond adequately to UDCA or as monotherapy in patients unable to tolerate UDCA. 

PBC is a rare, chronic cholestatic liver disease that destroys interlobular bile ducts and leads to cholestasis and liver fibrosis. Left untreated, the disease can worsen over time, leading to cirrhosis and liver transplant and, in some cases, premature death. PBC also harms quality of life, with patients often experiencing severe fatigue and pruritus.

Iqirvo, an oral dual peroxisome proliferator–activated receptor (PPAR) alpha and delta agonist, is the first new drug approved in nearly a decade for treatment of PBC. 

Accelerated approval of Iqirvo for PBC was based on data from the phase 3 ELATIVE trial published last year in The New England Journal of Medicine. 

The trial randomly assigned patients with PBC who had an inadequate response to or unacceptable side effects with UDCA to receive either once-daily elafibranor (80 mg) or placebo. 

The primary endpoint was a biochemical response, defined as an alkaline phosphatase (ALP) level < 1.67 times the upper limit of the normal range, with a reduction ≥ 15% from baseline, as well as normal total bilirubin levels.

Among 161 patients, a biochemical response was seen in 55 of 108 (51%) who received elafibranor vs 2 of 53 (4%) who received placebo. 

At week 52, the ALP level normalized in 15% of patients in the elafibranor group and none of the patients in the placebo group.

In a news release announcing approval of Iqirvo, the company notes that improvement in survival and prevention of liver decompensation events have not been demonstrated and that continued approval for PBC may be contingent upon verification and description of clinical benefit in confirmatory trials.

The most common adverse effects with Iqirvo, reported in ≥ 10% of study participants, were weight gain, abdominal pain, diarrhea, nausea, and vomiting. Iqirvo is not recommended for people who have or develop decompensated cirrhosis. Full prescribing information is available online. 

The data show that Iqirvo is “an effective second-line treatment for patients with PBC with favorable benefit and risk data,” Kris Kowdley, MD, AGAF, director of the Liver Institute Northwest in Seattle, Washington, and a primary investigator on the ELATIVE study, said in the news release. 

The approval of Iqirvo “will allow healthcare providers in the US to address an unmet need with the potential to significantly reduce ALP levels for our patients with PBC,” Dr. Kowdley said.

MILAN — Fecal microbiota transplantation (FMT), also known as intestinal microbiota transplantation, significantly reduced recurrence of hepatic encephalopathy, compared with placebo, in patients with cirrhosis on standard-of-care treatment, results of a phase 2 randomized controlled trial show. 

“Not only was FMT more beneficial, but also it didn’t matter which route of administration was used — oral or enema — which is good because people don’t really like enemas,” said Jasmohan S. Bajaj, MD, AGAF, professor, School of Medicine, Virginia Commonwealth University, Richmond, and hepatologist at Richmond VA Medical Center.

Resetting the Gut

The double-blind, randomized, placebo-controlled trial enrolled a total of 60 patients with cirrhosis who had experienced hepatic encephalopathy. Aged 61-65 years, participants had Model for End-Stage Liver Disease (MELD) scores of 12-13, all were taking lactulose and rifaximin, and all had experienced their last hepatic encephalopathy episode 8-13 months prior. 

Participants had similar baseline cognition, Sickness Impact Profile (SIP), and cirrhosis severity. Those with recent infections, taking other antibiotics, with a MELD score > 22, had received a transplant, or were immunosuppressed were excluded. 

Study participants were divided into four dose administration groups (n = 15 each): oral and enema active FMT therapy (group 1), oral active FMT and enema placebo (group 2), oral placebo and enema active FMT (group 3), and oral and enema placebo (group 4). 

The range of FMT dose frequency was zero (all placebo), or one, two, or three FMT administrations, each given 1 month apart. 

Two thirds of those receiving active FMT were given omnivore-donor FMT, and one third were given vegan-donor FMT, in addition to receiving standard of care. 

“Colony-forming units were standard and the same whether given via oral capsule or enema,” Dr. Bajaj said. This is “similar to what we used in our phase 1 study.”

Intent-to-treat (ITT) analysis was performed with 6-month data. The primary outcomes were safety and hepatic encephalopathy recurrence defined as ≥ grade 2 on West-Haven criteria. Secondary outcomes included other adverse events, changes in infections, severity of cirrhosis and cognition, and patient-reported outcomes. A statistical regression for hepatic encephalopathy recurrence was also performed. Patients were followed for 6 months or until death.
 

One Dose of FMT Better Than None

Hepatic encephalopathy recurrence was highest (40%) in group 4 patients, compared with those in group 1 (13%), group 2 (13%), and group 3 (0%), as were liver-related hospitalizations (47% vs 7%-20%). 

SIP total/physical and psych scores improved with FMT (P = .003).

When all patients were included in the analysis, the hepatic encephalopathy recurrence was related to dose number (odds radio [OR], 0.27; 95% CI, 0.10-0.79; P = .02), male sex (OR, 0.16; 95% CI, 0.03-0.89; P = .04), and physical SIP (OR, 1.05; 95% CI, 1.01-1.10, P = .05). However, when analyzing results from FMT recipients only, FMT dose, route of administration, and donor source were not found to affect recurrence. 

Of those on placebo alone, six patients (40%) had a recurrence, compared with four on FMT (8.8%) in the combined FMT groups. 

“As long as a patient received at least one FMT dose, they had a better response than a patient who had none,” Dr. Bajaj said.

Six patients dropped out; two in group 1 died after hepatic encephalopathy and falls, and one in group 2 died after a seizure. Three others did not return for follow-up visits. Four patients developed infections, including spontaneous bacterial peritonitis, cholecystitis, and cellulitis, all unrelated to FMT. 

“I think many patients in Western countries are underserved because apart from lactulose and rifaximin, there is little else to give them,” Dr. Bajaj said. “The assumption is because rifaximin kills everything, we shouldn’t give FMT. But here, we administered it to a harsh and hostile wasteland of microbiota, and it still got a toehold and generated a reduction in hepatic encephalopathy.”

He pointed out that in smaller prior studies, the effects lasted up to 1 year. 
 

Setting the Stage for Phase 3 Trials

Dr. Bajaj noted that this phase 2 study sets the stage for larger phase 3 trials in patients not responding to first-line therapy. 

“Given how well-tolerated and effective FMT appears to be in these patients, if the larger phase 3 trial shows similar results, I can imagine FMT becoming a standard therapy,” said Colleen R. Kelly, MD, AGAF, gastroenterologist at Brigham and Women’s Hospital and Harvard Medical School, Boston, who was not involved in the study.

MILAN — Fecal microbiota transplantation (FMT), also known as intestinal microbiota transplantation, significantly reduced recurrence of hepatic encephalopathy, compared with placebo, in patients with cirrhosis on standard-of-care treatment, results of a phase 2 randomized controlled trial show. 

“Not only was FMT more beneficial, but also it didn’t matter which route of administration was used — oral or enema — which is good because people don’t really like enemas,” said Jasmohan S. Bajaj, MD, AGAF, professor, School of Medicine, Virginia Commonwealth University, Richmond, and hepatologist at Richmond VA Medical Center.

Resetting the Gut

The double-blind, randomized, placebo-controlled trial enrolled a total of 60 patients with cirrhosis who had experienced hepatic encephalopathy. Aged 61-65 years, participants had Model for End-Stage Liver Disease (MELD) scores of 12-13, all were taking lactulose and rifaximin, and all had experienced their last hepatic encephalopathy episode 8-13 months prior. 

Participants had similar baseline cognition, Sickness Impact Profile (SIP), and cirrhosis severity. Those with recent infections, taking other antibiotics, with a MELD score > 22, had received a transplant, or were immunosuppressed were excluded. 

Study participants were divided into four dose administration groups (n = 15 each): oral and enema active FMT therapy (group 1), oral active FMT and enema placebo (group 2), oral placebo and enema active FMT (group 3), and oral and enema placebo (group 4). 

The range of FMT dose frequency was zero (all placebo), or one, two, or three FMT administrations, each given 1 month apart. 

Two thirds of those receiving active FMT were given omnivore-donor FMT, and one third were given vegan-donor FMT, in addition to receiving standard of care. 

“Colony-forming units were standard and the same whether given via oral capsule or enema,” Dr. Bajaj said. This is “similar to what we used in our phase 1 study.”

Intent-to-treat (ITT) analysis was performed with 6-month data. The primary outcomes were safety and hepatic encephalopathy recurrence defined as ≥ grade 2 on West-Haven criteria. Secondary outcomes included other adverse events, changes in infections, severity of cirrhosis and cognition, and patient-reported outcomes. A statistical regression for hepatic encephalopathy recurrence was also performed. Patients were followed for 6 months or until death.
 

One Dose of FMT Better Than None

The Fibrosis-4 (FIB-4) index shows high discordance with liver stiffness measurement (LSM) via transient elastography, suggesting that many patients are misclassified, potentially impacting clinical decisions, according to investigators.

These findings call for a cautious interpretation of low-risk FIB-4 results among patients at greatest risk of misclassification, and/or use of alternative assessment strategies, reported Mazen Noureddin, MD, MHSc, of Houston Methodist Hospital, and coauthors.

swesabobogathobegeuecucheticrithucrufromocaphemaluclemulawromilokuswagucinobegitorilaspouaposididefrolowraprobeseswewrigivepr

“Currently, the AGA/AASLD Pathways recommends identifying patients at risk for metabolic dysfunction-associated steatotic liver disease (MASLD), then using sequential testing with FIB-4 followed by FibroScan to risk-stratify patients,” the investigators wrote in Clinical Gastroenterology and Hepatology.

Yet the performance of the FIB-4 index in this context remains unclear.

“Previous studies have shown FIB-4 to have low accuracy for screening liver fibrosis, especially among obese and diabetic patients,” the investigators wrote. “Thus, there is a concern that classifying patients with FIB-4 can lead to misclassification and missed diagnosis.”

To explore this concern, Dr. Noureddin and colleagues turned to data from the 2017-2020 National Health and Nutrition Examination Surveys, including 5285 subjects at risk for MASLD. Exclusions were made for those with excessive alcohol intake or other liver diseases, resulting in a final cohort of 3741 individuals.

All subjects were classified as low-, indeterminate-, or high-risk for advanced liver fibrosis based on FIB-4 scores. These scores were then compared with liver stiffness measurements (LSM) obtained through transient elastography (FibroScan).

Out of 2776 subjects classified as low-risk by FIB-4, 277 (10%) were reclassified as higher risk by LSM, including 75 (2.7%) who were found to be at high risk. Out of 879 subjects with indeterminate FIB-4 scores, 37 (4.2%) were at high risk according to LSM. Finally, among the 86 subjects classified as high risk by FIB-4, 68 (79.1%) were reclassified as lower risk by LSM, including 54 (62.8%) who were deemed low risk.

Subjects misclassified as low risk by FIB-4 were typically older and had higher waist circumferences, body mass indices, glycohemoglobin A1c levels, fasting glucose levels, liver enzyme levels, diastolic blood pressures, controlled attenuation parameter scores, white blood cell counts, and alkaline phosphatase levels, but lower high-density lipoprotein and albumin levels (all P less than .05). They were also more likely to have prediabetes or diabetes.

“[I]t is important to acknowledge that 10% of the subjects were misclassified as low risk by FIB-4,” Dr. Noureddin and colleagues wrote, including 2.7% of patients who were actually high risk. “This misclassification of high-risk patients can lead to missed diagnoses, delaying crucial medical treatments or lifestyle interventions.”

They therefore suggested cautious interpretation of low-risk FIB-4 results among patients with factors predicting misclassification, or even use of alternative diagnostic strategies.

“Some possible alternatives to FIB-4 include new serum tests such NIS-2+, MASEF, SAFE score, and machine learning methods,” Dr. Noureddin and colleagues wrote. “However, additional confirmatory and cost-effective studies are required to validate the effectiveness of these tests, including studies conducted on the general population.”

The investigators disclosed relationships with AbbVie, Corcept, Galectin, and others.

WASHINGTON — Microbiota-focused dietary therapy could improve disease outcomes and management of metabolic dysfunction-associated steatotic liver disease (MASLD), according to a study presented at the annual Digestive Disease Week^® (DDW).

For instance, patients with MASLD had lower intake of fiber and omega-3 fatty acids but higher consumption of added sugars and ultraprocessed foods, which correlated with the associated bacterial species and functional pathways.

“MASLD is an escalating concern globally, which highlights the need for innovative targets for disease prevention and management,” said lead author Georgina Williams, PhD, a postdoctoral researcher in diet and gastroenterology at the University of Newcastle, Australia.

“Therapeutic options often rely on lifestyle modifications, with a focus on weight loss,” she said. “Diet is considered a key component of disease management.”

Although calorie restriction with a 3%-5% fat loss is associated with hepatic benefits in MASLD, Dr. Williams noted, researchers have considered whole dietary patterns and the best fit for patients. Aspects of the Mediterranean diet may be effective, as reflected in recommendations from the American Association for the Study of Liver Disease (AASLD), which highlight dietary components such as limited carbohydrates and saturated fat, along with high fiber and unsaturated fats. The gut microbiome may be essential to consider as well, she said, given MASLD-associated differences in bile acid metabolism, inflammation, and ethanol production.

Dr. Williams and colleagues conducted a retrospective case-control study in an outpatient liver clinic to understand diet and dysbiosis in MASLD, looking at differences in diet, gut microbiota composition, and functional pathways in those with and without MASLD. The researchers investigated daily average intake, serum, and stool samples among 50 people (25 per group) matched for age and gender, comparing fibrosis-4, MASLD severity scores, macronutrients, micronutrients, food groups, metagenomic sequencing, and inflammatory markers such as interleukin (IL)-1ß, IL-6, tumor necrosis factor (TNF)-α, cytokeratin (CK)-18, and high-sensitivity C-reactive protein (hsCRP).
 

Dietary Characteristics

At baseline, the groups differed by ethnicity, prescription medication use, and body mass index (BMI), where the MASLD group had greater ethnic diversity, medication use, and BMI. In addition, the MASLD group had a zero to mild score of fibrosis.

Overall, energy intake didn’t differ significantly between the two groups. The control group had higher alcohol intake, likely since the MASLD group was recommended to reduce alcohol intake, though the difference was about 5 grams per day. The MASLD group also had less caffeine intake than the control group, as well as slightly lower protein intake, though the differences weren’t statistically significant.

While consumption of total carbohydrates didn’t differ significantly between the groups, participants with MASLD consumed more calories from carbohydrates than did the controls. The MASLD group consumed more calories from added and free sugars and didn’t meet recommendations for dietary fiber.

With particular food groups, participants with MASLD ate significantly fewer whole grains, red and orange fruits, and leafy green vegetables. When consuming fruit, those with MASLD were more likely to drink juice than eat whole fruit. These findings could be relevant when considering high sugar intake and low dietary fiber, Dr. Williams said.

With dietary fat, there were no differences in total fat between the groups, but the fat profiles differed. The control group was significantly more likely to consume omega-3 fatty acids, including alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), docosapentaenoic acid (DPA), and docosahexaenoic acid (DHA). The MASLD group was less likely to consume seafood, nuts, seeds, avocado, and olive oil.

With inflammatory markers, hsCRP and CK-18 were increased in MASLD, while IL-1ß was increased in controls, which was consistently associated with higher alcohol intake among the control group. IL-6 and TNF-α didn’t differ between the groups.

Notably, dietary fats were most consistently associated with inflammatory markers, Dr. Williams said, with inflammation being positively associated with saturated fats and negatively associated with unsaturated fats.

Looking at microbiota, the alpha diversity was no different, but the beta diversity was across 162 taxa. Per bacterial species, there was an inverse relationship between MASLD and associations with unsaturated fat, as well as positive indicators of high sugar and fructose intake and low unsaturated fat and dietary fiber intake.

Beyond that, the functional pathways enriched in MASLD were associated with increased sugar and carbohydrates, reduced fiber, and reduced unsaturated fat. Lower butyrate production in MASLD was associated with low intake of nuts, seeds, and unsaturated fat.
 

In Clinical Practice

Dr. Williams suggested reinforcing AASLD guidelines and looking at diet quality, not just diet quantity. Although an energy deficit remains relevant in MASLD, macronutrient consumption matters across dietary fats, fibers, and sugars.

Future avenues for research include metabolomic pathways related to bile acids and fatty acids, she said, as well as disentangling metabolic syndrome from MASLD outcomes.

Session moderator Olivier Barbier, PhD, professor of pharmacy at Laval University in Quebec, Canada, asked about microbiome differences across countries. Dr. Williams noted the limitations in this study of looking at differences across geography and ethnicity, particularly in Australia, but said the species identified were consistent with those found in most literature globally.

In response to other questions after the presentation, Dr. Williams said supplements (such as omega-3 fatty acids) were included in total intake, and those taking prebiotics or probiotics were excluded from the study. In an upcoming clinical trial, she and colleagues plan to control for household microbiomes as well.

“The premise is that microbiomes are shared between households, so when you’re doing these sorts of large-scale clinical studies, if you’re going to look at the microbiome, then you should control for one of the major confounding variables,” said Mark Sundrud, PhD, professor of medicine at the Dartmouth Center for Digestive Health in Lebanon, New Hampshire. Dr. Sundrud, who wasn’t involved with this study, presented on the role of bile acids in mucosal immune cell function at DDW.

“We’ve done a collaborative study looking at microbiomes and bile acids in inflammatory bowel disease (IBD) patients versus controls,” which included consideration of households, he said. “We were able to see more intrinsic disease-specific changes.”

Dr. Williams declared no relevant disclosures. Dr. Sundrud has served as a scientific adviser to Sage Therapeutics.

Future avenues for research include metabolomic pathways related to bile acids and fatty acids, she said, as well as disentangling metabolic syndrome from MASLD outcomes.

Session moderator Olivier Barbier, PhD, professor of pharmacy at Laval University in Quebec, Canada, asked about microbiome differences across countries. Dr. Williams noted the limitations in this study of looking at differences across geography and ethnicity, particularly in Australia, but said the species identified were consistent with those found in most literature globally.

In response to other questions after the presentation, Dr. Williams said supplements (such as omega-3 fatty acids) were included in total intake, and those taking prebiotics or probiotics were excluded from the study. In an upcoming clinical trial, she and colleagues plan to control for household microbiomes as well.

“The premise is that microbiomes are shared between households, so when you’re doing these sorts of large-scale clinical studies, if you’re going to look at the microbiome, then you should control for one of the major confounding variables,” said Mark Sundrud, PhD, professor of medicine at the Dartmouth Center for Digestive Health in Lebanon, New Hampshire. Dr. Sundrud, who wasn’t involved with this study, presented on the role of bile acids in mucosal immune cell function at DDW.

“We’ve done a collaborative study looking at microbiomes and bile acids in inflammatory bowel disease (IBD) patients versus controls,” which included consideration of households, he said. “We were able to see more intrinsic disease-specific changes.”

WASHINGTON — Microbiota-focused dietary therapy could improve disease outcomes and management of metabolic dysfunction-associated steatotic liver disease (MASLD), according to a study presented at the annual Digestive Disease Week^® (DDW).

For instance, patients with MASLD had lower intake of fiber and omega-3 fatty acids but higher consumption of added sugars and ultraprocessed foods, which correlated with the associated bacterial species and functional pathways.

“MASLD is an escalating concern globally, which highlights the need for innovative targets for disease prevention and management,” said lead author Georgina Williams, PhD, a postdoctoral researcher in diet and gastroenterology at the University of Newcastle, Australia.

“Therapeutic options often rely on lifestyle modifications, with a focus on weight loss,” she said. “Diet is considered a key component of disease management.”

Although calorie restriction with a 3%-5% fat loss is associated with hepatic benefits in MASLD, Dr. Williams noted, researchers have considered whole dietary patterns and the best fit for patients. Aspects of the Mediterranean diet may be effective, as reflected in recommendations from the American Association for the Study of Liver Disease (AASLD), which highlight dietary components such as limited carbohydrates and saturated fat, along with high fiber and unsaturated fats. The gut microbiome may be essential to consider as well, she said, given MASLD-associated differences in bile acid metabolism, inflammation, and ethanol production.

Dr. Williams and colleagues conducted a retrospective case-control study in an outpatient liver clinic to understand diet and dysbiosis in MASLD, looking at differences in diet, gut microbiota composition, and functional pathways in those with and without MASLD. The researchers investigated daily average intake, serum, and stool samples among 50 people (25 per group) matched for age and gender, comparing fibrosis-4, MASLD severity scores, macronutrients, micronutrients, food groups, metagenomic sequencing, and inflammatory markers such as interleukin (IL)-1ß, IL-6, tumor necrosis factor (TNF)-α, cytokeratin (CK)-18, and high-sensitivity C-reactive protein (hsCRP).
 

Dietary Characteristics

At baseline, the groups differed by ethnicity, prescription medication use, and body mass index (BMI), where the MASLD group had greater ethnic diversity, medication use, and BMI. In addition, the MASLD group had a zero to mild score of fibrosis.

Overall, energy intake didn’t differ significantly between the two groups. The control group had higher alcohol intake, likely since the MASLD group was recommended to reduce alcohol intake, though the difference was about 5 grams per day. The MASLD group also had less caffeine intake than the control group, as well as slightly lower protein intake, though the differences weren’t statistically significant.

While consumption of total carbohydrates didn’t differ significantly between the groups, participants with MASLD consumed more calories from carbohydrates than did the controls. The MASLD group consumed more calories from added and free sugars and didn’t meet recommendations for dietary fiber.

With particular food groups, participants with MASLD ate significantly fewer whole grains, red and orange fruits, and leafy green vegetables. When consuming fruit, those with MASLD were more likely to drink juice than eat whole fruit. These findings could be relevant when considering high sugar intake and low dietary fiber, Dr. Williams said.

With dietary fat, there were no differences in total fat between the groups, but the fat profiles differed. The control group was significantly more likely to consume omega-3 fatty acids, including alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), docosapentaenoic acid (DPA), and docosahexaenoic acid (DHA). The MASLD group was less likely to consume seafood, nuts, seeds, avocado, and olive oil.

With inflammatory markers, hsCRP and CK-18 were increased in MASLD, while IL-1ß was increased in controls, which was consistently associated with higher alcohol intake among the control group. IL-6 and TNF-α didn’t differ between the groups.

Notably, dietary fats were most consistently associated with inflammatory markers, Dr. Williams said, with inflammation being positively associated with saturated fats and negatively associated with unsaturated fats.

Looking at microbiota, the alpha diversity was no different, but the beta diversity was across 162 taxa. Per bacterial species, there was an inverse relationship between MASLD and associations with unsaturated fat, as well as positive indicators of high sugar and fructose intake and low unsaturated fat and dietary fiber intake.

Beyond that, the functional pathways enriched in MASLD were associated with increased sugar and carbohydrates, reduced fiber, and reduced unsaturated fat. Lower butyrate production in MASLD was associated with low intake of nuts, seeds, and unsaturated fat.

TOPLINE:

Healthier sleep is associated with lower odds of developing a wide range of gastrointestinal conditions, regardless of genetic susceptibility, new research revealed.

METHODOLOGY:

• Due to the widespread prevalence of sleep issues and a growing burden of digestive diseases globally, researchers investigated the association between sleep quality and digestive disorders in a prospective cohort study of 410,586 people in the UK Biobank.
• Five individual sleep behaviors were assessed: sleep duration, insomnia, snoring, daytime sleepiness, and chronotype.
• A healthy sleep was defined as a morning chronotype, 7-8 hours of sleep duration, no self-reported snoring, never or rare insomnia, and a low frequency of daytime sleepiness, for a score of 5/5.
• The study investigators tracked the development of 16 digestive diseases over a mean period of 13.2 years.
• As well as looking at healthy sleep scores, researchers considered genetic susceptibility to gastrointestinal conditions.

TAKEAWAY:

• Participants with a healthy sleep score had 28% lower odds of developing any digestive disease (hazard ratio [HR], 0.72; 95% CI, 0.69-0.75) than those with a sleep score of 0/1.
• Of the 16 digestive diseases looked at, the reduction of risk was highest for irritable bowel syndrome at 50% (HR, 0.50; 95% CI, 0.45-0.57).
• A healthy sleep score was also associated with 37% reduced odds for metabolic dysfunction–associated steatotic liver disease (formerly known as nonalcoholic fatty liver disease; HR, 0.63; 95% CI, 0.55-0.71), 35% lower chance for peptic ulcer (HR, 0.65; 95% CI, 0.058-0.74), 34% reduced chance for dyspepsia (HR, 0.66; 95% CI, 0.58-0.75), and a 25% lower risk for diverticulosis (HR, 0.75; 95% CI, 0.71-0.80).
• High genetic risk and poor sleep scores were also associated with increased odds (53% to > 200%) of developing digestive diseases.
• However, healthy sleep reduced the risk for digestive diseases regardless of genetic susceptibility.

IN PRACTICE:

“Our findings underscore the potential holistic impact of different sleep behaviors in mitigating the risk of digestive diseases in clinical practice,” wrote Shiyi Yu, MD, of Guangdong Provincial People’s Hospital, Guangzhou, Guangdong, China, and colleagues.

Poor sleep can also change our gut microbiome, Dr. Yu told this news organization. If you don’t sleep well, the repair of the gut lining cannot be finished during the night.

WASHINGTON — Statin use may contribute to a significant reduction in the risk of new primary sclerosing cholangitis (PSC) among patients with inflammatory bowel disease (IBD), according to a study presented at Digestive Disease Week^® (DDW) 2024.

Statin use was associated with an 86% risk reduction, and only .09% of IBD patients who took statins developed PSC.

“We all take care of patients with liver disease, and we know what a significant burden PSC is. These patients have a significantly elevated risk of enhanced fibrosis and cirrhosis, multiple cancers, and cholangitis and sepsis,” said lead author Chiraag Kulkarni, MD, a gastroenterology fellow at Stanford (California) University Medical School.

“Despite this, we have to date no proven effective medical care for PSC,” he said. “However, over the last decade, there is growing evidence that statins may be beneficial in liver disease, and we see this evidence base stretching from basic science to clinical data.”

Dr. Kulkarni pointed to numerous studies that indicate statins may slow disease progression in steatotic liver disease, viral hepatitis, and cirrhosis. But could statins prevent the onset of PSC?

Because PSC incidence is low, Dr. Kulkarni and colleagues focused on a patient population with higher prevalence — those with IBD, who have an overall lifetime risk of 2% to 7%. The research team followed patients from the date of IBD diagnosis.

Among 33,813 patients with IBD in a national dataset from 2018 onward, 8813 used statins. Statin users tended to be older than non–statin users.

Overall, 181 patients developed new onset PSC during a median follow-up of about 45 months after initial IBD diagnosis. Only eight statin users (.09%) developed PSC, compared with 173 patients (.69%) in the control group.

In a propensity score-matched analysis, statin therapy was associated with a significantly lower risk of developing PSC (HR .14, P < .001). The associated E-value was 5.5, which suggested a robust finding and unlikely to be due to non-visible confounding.

The findings were consistent across secondary and sensitivity analyses, including by age, duration of statin use, and type of statin. For instance, for patients under age 50 where PSC is more likely to occur, statins were associated with a 90% reduction in PSC risk.

“We take away two things from this. First, it’s suggested that a protective effect occurs at ages where PSC is most likely to occur,” Dr. Kulkarni said. “Second, in combination with our propensity score-matched analysis, the results we are observing are not due to a survival bias, where the patients who survive to an age where statins are prescribed simply have a biologically different predilection for developing PSC.”

Statins also protected against PSC in both ulcerative colitis (HR .21) and Crohn’s disease (HR .15), as well as both women (HR .16) and men (HR .22).

Given the uncertainty about the optimal duration of statin therapy for a protective effect, Dr. Kulkarni and colleagues looked at a lag time of 12 months. They found statins were associated with an 84% risk reduction (HR .16), which was similar to the primary analysis.

The study was limited by the inability to capture dosage data or medication adherence. The findings raised several questions, Dr. Kulkarni said, such as the underlying mechanisms and clinical implications. For instance, the underlying mechanisms appear to be related to the pleiotropic effect of statins, modulation of gut inflammation, and alterations in bile acid profiles.

“This is really fascinating and interesting. I wonder about this as a primary prevention strategy in those who have normal cholesterol. Could this work or not?” said Gyongyi Szabo, MD, AGAF, chief academic officer at Beth Israel Deaconess Medical Center, Boston, who was a moderator for the Liver & Biliary Section Distinguished Abstract Plenary Session.

One in nine patients with steatotic liver disease reported concurrent alcohol use, and more than 11% reported high-risk consumption, a national study of more than a million US veterans found.

Moreover, the combination of steatotic liver disease and high-risk alcohol intake carried a more than 43% higher long-term risk of liver cirrhosis compared with no alcohol use, according to researchers led by Robert J. Wong, MD, MS, of the Division of Gastroenterology and Hepatology, Veterans Affairs Healthcare System Palo Alto, at Stanford University School of Medicine in Palo Alto, California.

However, the study found that “reducing alcohol use lowers risk of cirrhosis, emphasizing the importance of timely alcohol use assessment and early interventions to address high-risk alcohol use in steatotic liver disease,” Dr. Wong and associates wrote in Gastroenterology.

Although concurrent moderate to heavy alcohol intake would be expected to lead more rapidly to liver disease progression, the existing literature has been conflicting, the authors noted. Several studies have even found moderate alcohol associated with a lower risk of advanced liver disease among MASLD patients, including that by Dunn et al. .
 

The Study

MASLD patients were identified through the US Veterans Affairs Corporate Data Warehouse from January 1, 2010, through December 31, 2017, with follow-up through December 31, 2022.

Alcohol use was assessed by Alcohol Use Disorders Identification Test–Concise (AUDIT-C) scores and was categorized as follows: no alcohol (AUDIT-C = 0), low-risk alcohol use (AUDIT-C 1-2 for women and 1–3 for men), and high-risk alcohol (AUDIT-C ≥ 3 for women and ≥ 4 for men).

Among the 1,156,189 veterans with MASLD, 54.2% reported no alcohol, 34.6% low-risk alcohol, and 11.2% high-risk alcohol use. In median follow-up of nine to 10 years, incidence rates of cirrhosis were .53 per 100 person-years for no use, .42 for low-risk use, and .76 for high-risk use.

In contrast to patients with baseline high-risk alcohol intake who reported no change in use, those who decreased their alcohol intake during follow-up experienced a 39% reduction in the long-term risk of cirrhosis, for a hazard ratio of .61 (95% CI, .45-.83, P < .01).

One in nine patients with steatotic liver disease reported concurrent alcohol use, and more than 11% reported high-risk consumption, a national study of more than a million US veterans found.

Moreover, the combination of steatotic liver disease and high-risk alcohol intake carried a more than 43% higher long-term risk of liver cirrhosis compared with no alcohol use, according to researchers led by Robert J. Wong, MD, MS, of the Division of Gastroenterology and Hepatology, Veterans Affairs Healthcare System Palo Alto, at Stanford University School of Medicine in Palo Alto, California.

However, the study found that “reducing alcohol use lowers risk of cirrhosis, emphasizing the importance of timely alcohol use assessment and early interventions to address high-risk alcohol use in steatotic liver disease,” Dr. Wong and associates wrote in Gastroenterology.

Although concurrent moderate to heavy alcohol intake would be expected to lead more rapidly to liver disease progression, the existing literature has been conflicting, the authors noted. Several studies have even found moderate alcohol associated with a lower risk of advanced liver disease among MASLD patients, including that by Dunn et al. .
 

The Study

MASLD patients were identified through the US Veterans Affairs Corporate Data Warehouse from January 1, 2010, through December 31, 2017, with follow-up through December 31, 2022.

Alcohol use was assessed by Alcohol Use Disorders Identification Test–Concise (AUDIT-C) scores and was categorized as follows: no alcohol (AUDIT-C = 0), low-risk alcohol use (AUDIT-C 1-2 for women and 1–3 for men), and high-risk alcohol (AUDIT-C ≥ 3 for women and ≥ 4 for men).

Among the 1,156,189 veterans with MASLD, 54.2% reported no alcohol, 34.6% low-risk alcohol, and 11.2% high-risk alcohol use. In median follow-up of nine to 10 years, incidence rates of cirrhosis were .53 per 100 person-years for no use, .42 for low-risk use, and .76 for high-risk use.

In contrast to patients with baseline high-risk alcohol intake who reported no change in use, those who decreased their alcohol intake during follow-up experienced a 39% reduction in the long-term risk of cirrhosis, for a hazard ratio of .61 (95% CI, .45-.83, P < .01).
