Fidaxomicin favored over vancomycin in real-world C. diff study

Fidaxomicin (Fificid) emerged favorable to vancomycin for the treatment of both initial and recurrent Clostridioides difficile infections in a Medicare population, according to a new retrospective study.

Although fidaxomicin was about 14% more effective than vancomycin in treating the initial infection, a larger difference of 30% was found among people with recurrent C. diff. infections.

Lead investigator Erik Dubberke, MD, professor of infectious diseases at the University of Washington, St. Louis, and colleagues noted that this real-world evidence of the two agents used to treat C. diff. was “strikingly similar” to clinical trial data.

They said that their findings support the 2021 change in clinical guidelines from the Infectious Diseases Society of America recommending fidaxomicin over vancomycin.

The study was presented at Digestive Disease Week® (DDW) 2022, which was held virtually and in San Diego.
 

Evaluating a high-risk population

Because few real-world data exist that compare these two agents for C. diff., “particularly in a high-risk, high-prevalence population like Medicare,” the researchers evaluated Medicare Parts A, B, and D claims from 2016 to 2018 and included patients who had received fidaxomicin or vancomycin for an initial episode of C. diff. and for any recurrent episodes.

The researchers compared sustained response and recurrence of C. diff. within 4 weeks and 8 weeks after initial treatment with fidaxomicin or vancomycin. Treatment was considered successful if clinical resolution occurred 1 day after finishing therapy and there was no evidence of C. diff. recurrence.

Recurrence of C. diff. was defined as any evidence of new treatment or hospitalization for the infection within 4 or 8 weeks of when a patient filled the prescription for fidaxomicin or vancomycin.

The treatment groups were similar in age and race. However, the fidaxomicin group was at higher risk for recurrence, owing to risk factors such as history of C. diff. infection and compromised immunity. To reduce bias in comparing the groups, Dr. Dubberke and colleagues used propensity score matching. This approach yielded 190 matched pairs in the initial C. diff. episode sample and 67 matched pairs in the recurrent episode sample.

Among patients with their first C. diff. infection, fidaxomicin had a 13.5% higher rate of 4-week sustained response, compared with vancomycin (71.7% vs. 58.2%; P = .0058). There was also a 13.2% higher rate for 8-week sustained response with fidaxomicin (63.2% vs. 50.0%; P = .0114).

Sustained response at 4 weeks and 8 weeks among the patients who experienced a recurrent episode of C. diff. favored fidaxomicin over vancomycin by 30.1% (P = .0002) and 27.6% (P = .0012), respectively.

The rates of C. diff. recurrence in patients who experienced their first C. diff. infection or who experienced a recurrent bout were lower with fidaxomicin than vancomycin, but the differences were not statistically significant.
 

A costly edge

When asked to comment, Colleen Kelly, MD, a gastroenterologist and associate professor of medicine at Brown University, Providence, R.I., said that the study was “worthwhile” and added that “Eric Dubberke has done a lot of work in this area.”

The study “gives more evidence that fidaxomicin does have a bit of an edge in people who have already had a bout of C. diff.,” she said.

Dr. Kelly added that the cost needs to be considered. Fidaxomicin “is about 30 times more expensive than vancomycin,” she said.

In part because of the cost difference, the American College of Gastroenterology (ACG) 2021 guidelines, which Dr. Kelly helped create, recommend that fidaxomicin be held as a second-line agent. The ACG guidance reserved fidaxomicin for people with C. diff. for whom initial treatment with vancomycin failed.

“The fidaxomicin question is going to get a lot easier once the cost of the drug comes down,” Dr. Kelly said.

The study was funded by Merck. Dr. Dubberke is a consultant for Merck. Dr. Kelly reports no relevant financial relationships.

More evidence dementia not linked to PPI use in older people

Article Type
Changed
Tue, 05/31/2022 - 13:33

Controversy regarding the purported link between the use of proton pump inhibitors (PPIs) or histamine H2 receptor antagonists (H2RAs) and risk for dementia continues.

Adding to the “no link” column comes new evidence from a study presented at the annual Digestive Disease Week® (DDW) .

Among almost 19,000 people, no association was found between the use of these agents and a greater likelihood of incident dementia, Alzheimer’s disease, or cognitive decline in people older than 65 years.

“We found that baseline PPI or H2RA use in older adults was not associated with dementia, with mild cognitive impairment, or declines in cognitive scores over time,” said lead author Raaj Shishir Mehta, MD, a gastroenterology fellow at Massachusetts General Hospital in Boston.

“While deprescribing efforts are important, especially when medications are not indicated, these data provide reassurance about the cognitive impacts of long-term use of PPIs in older adults,” he added.
 

Growing use, growing concern

As PPI use has increased worldwide, so too have concerns over the adverse effects from their long-term use, Dr. Mehta said.

“One particular area of concern, especially among older adults, is the link between long-term PPI use and risk for dementia,” he said.

Igniting the controversy was a February 2016 study published in JAMA Neurology that showed a positive association between PPI use and dementia in residents of Germany aged 75 years and older. Researchers linked PPI use to a 44% increased risk of dementia over 5 years.

The 2016 study was based on claims data, which can introduce “inaccuracy or bias in defining dementia cases,” Dr. Mehta said. He noted that it and other previous studies also were limited by an inability to account for concomitant medications or comorbidities.

To overcome these limitations in their study, Dr. Mehta and colleagues analyzed medication data collected during in-person visits and asked experts to confirm dementia outcomes. The research data come from ASPREE, a large aspirin study of 18,846 people older than 65 years in the United States and Australia. Participants were enrolled from 2010 to 2014. A total of 566 people developed incident dementia during follow-up.

The researchers had data on alcohol consumption and other lifestyle factors, as well as information on comorbidities, hospitalizations, and overall well-being.

“Perhaps the biggest strength of our study is our rigorous neurocognitive assessments,” Dr. Mehta said.

They assessed cognition at baseline and at years 1, 3, 5, and 7 using a battery of tests. An expert panel of neurologists, neuropsychologists, and geriatricians adjudicated cases of dementia, in accordance with DSM-IV criteria. If the diagnosis was unclear, they referred people for additional workup, including neuroimaging.

Cox proportional hazards, regression, and/or mixed effects modeling were used to relate medication use with cognitive scores.

All analyses were adjusted for age, sex, body mass index, alcohol use, family history of dementia, medications, and other medical comorbidities.

At baseline, PPI users were more likely to be White, have fewer years of education, and have higher rates of hypertension, diabetes, and kidney disease. This group also was more likely to be taking five or more medications.
 

 

 

Key points

During 80,976 person-years of follow-up, there were 566 incident cases of dementia, including 235 probable cases of Alzheimer’s disease and 331 other dementias.

Baseline PPI use, in comparison with nonuse, was not associated with incident dementia (hazard ratio, 0.86; 95% confidence interval, 0.70-1.05).

“Similarly, when we look specifically at Alzheimer’s disease or mixed types of dementia, we find no association between baseline PPI use and dementia,” Dr. Mehta said.

When they excluded people already taking PPIs at baseline, they found no association between starting PPIs and developing dementia over time.

Secondary aims of the study included looking for a link between PPI use and mild cognitive impairment or significant changes in cognition over time. In both cases, no association emerged. PPI use at baseline also was not associated with cognitive impairment/no dementia (also known as mild cognitive impairment) or with changes in overall cognitive test scores over time.

To determine whether any association could be a class effect of acid suppression medication, they assessed use of H2RA medications and development of incident dementia. Again, the researchers found no link.

A diverse multinational population from urban and rural areas was a strength of the study, as was the “very rigorous cognitive testing with expert adjudication of our endpoints,” Dr. Mehta said. In addition, fewer than 5% of patients were lost to follow-up.

In terms of limitations, this was an observational study “so residual confounding is always possible,” he added. “But I’ll emphasize that we are among the largest studies to date with wealth of covariates.”
 

Why the different findings?

The study was “really well done,” session moderator Paul Moayyedi, MD, said during the Q&A session at DDW 2022.

Dr. Moayyedi, a professor of medicine at McMaster University, Hamilton, Ont., asked Dr. Mehta why he “found absolutely no signal, whereas the German study did.”

“It’s a good question,” Dr. Mehta responded. “If you look across the board, there have been conflicting results.”

The disparity could be related to how researchers conducting claims data studies classify dementia, he noted.

“If you look at the nitty-gritty details over 5 years, almost 40% of participants [in those studies] end up with a diagnosis of dementia, which is quite high,” Dr. Mehta said. “That raises questions about whether the diagnosis of dementia is truly accurate.”

Dr. Mehta and Dr. Moayyedi reported no relevant financial relationships.

Vibrating pill counters constipation

Article Type
Changed
Wed, 05/25/2022 - 10:37

A swallowable, vibrating capsule improved symptoms among patients with chronic idiopathic constipation in a phase 3 multicenter, randomized, controlled trial. The method represents a mechanical approach to the treatment of constipation.

The swallowable pill acts by vibrating during passage through the gut, where it is thought to augment colonic biorhythm and peristalsis. Traditional treatments for constipation generally increase motility or secretion.

“That’s how we have been managing constipation since time immemorial. Now we have come up with this novel approach, where there’s a pill that is designed to increase local oscillations, and probably induce local contractions of the colon to mimic what happens normally,” said Satish Rao, MD, PhD, who presented the results of the trial at the annual Digestive Disease Week® (DDW).

“We’re now seeing that local stimulation works, and the other neat thing seems to be a lack of side effects, which is really a huge plus. I think it will benefit people with both occasional or chronic constipation,” said Dr. Rao, professor of medicine at Medical College of Georgia, Augusta.

The capsules activate for two stimulation cycles, each lasting for about 2 hours. The cycle includes 3 seconds of vibration followed by 16 seconds of rest.

The researchers conducted a study with two active arms and a placebo. It included 312 patients age 22 or older who had an average of between 1 and 2.5 spontaneous bowel movements (SBM) per week.

Treatment lasted for 8 weeks, with patients ingesting a capsule between 9 and 10 p.m. In one treatment group, the device was activated at 6 a.m., and in the other group at about 2 p.m.

The placebo and treatment groups had similar baseline characteristics, except for a longer duration of constipation in the treatment groups (17.9 versus 14.5 years; P = .0253). In an intention-to-treat analysis, the treatment groups were more likely to achieve an increase of one complete SBM per week (39.26% versus 22.15%; P < .0001) and an increase of two complete SBMs per week (22.7% versus 11.41%; P < .0006).

The capsules also improved straining score, stool consistency, and quality of life. There was no significant difference between treatment and placebo groups with respect to bloating or rescue medication use.

The product had few adverse effects. The most common was a vibrating sensation or discomfort (11.0%, versus none in the placebo group).

Dr. Rao expects that the treatment could be widely applicable since many constipation patients don’t gain sufficient benefit from existing treatments, or find side effects intolerable.

Another benefit is that the therapy’s mimicry of natural cycles appears to grant patients more control of bowel movements. Laxatives and other pharmaceutical interventions may prompt the patient to go to the bathroom within an hour or two, but patients in the trial reported bowel movements at predictable times.

However, he noted that the pill is nondissolvable, which would make it contraindicated for patients who have had previous gut surgeries or narrowing of the gut. He noted that the sponsoring company, Vibrant Gastro, expects to obtain Food and Drug Administration approval by the end of 2022.

The results of the study were well received. “I think it’s an exciting new approach for managing patients with chronic constipation. It was a large sample size, and the treatment seems to be well tolerated. It may offer a promising option for patients who have not responded to many other medications,” said Adil E. Bharucha, MD, who comoderated the session where the research was presented.

However, he pointed out that the presentation did not indicate how many of the patients had previously tried other therapies. “We’d like to see the full paper, which will provide a better understanding of the role of this treatment in practice down the road,” said Dr. Bharucha, professor of medicine in the division of gastroenterology and hepatology and director of the office of clinical trials at Mayo Clinic, Rochester, Minn.

The capsule may not work for everyone, said Dr. Bharucha. He suspects that many refractory patients have an issue with pelvic floor muscles, which may restrict stool evacuation. “You wouldn’t expect those people to respond optimally to a laxative and I suspect perhaps not to a capsule, either. I think defecatory disorders are substantially underdiagnosed in patients who don’t respond to laxatives,” said Dr. Bharucha.

Asked why the capsule might benefit patients who don’t improve with laxatives, Dr. Bharucha responded: “I think we need more studies to understand how the capsule works.”

A swallowable, vibrating capsule improved symptoms among patients with chronic idiopathic constipation in a phase 3 multicenter, randomized, controlled trial. The method represents a mechanical approach to the treatment of constipation.

The swallowable pill acts by vibrating during passage through the gut, where it is thought to augment colonic biorhythm and peristalsis. Traditional treatments for constipation generally increase motility or secretion.

“That’s how we have been managing constipation since time immemorial. Now we have come up with this novel approach, where there’s a pill that is designed to increase local oscillations, and probably induce local contractions of the colon to mimic what happens normally,” said Satish Rao, MD, PhD, who presented the results of the trial at the annual Digestive Disease Week® (DDW).

“We’re now seeing that local stimulation works, and the other neat thing seems to be a lack of side effects, which is really a huge plus. I think it will benefit people with both occasional or chronic constipation,” said Dr. Rao, professor of medicine at Medical College of Georgia, Augusta.

The capsules activate for two stimulation cycles, each lasting for about 2 hours. The cycle includes 3 seconds of vibration followed by 16 seconds of rest.

The researchers conducted a study with two active arms and a placebo. It included 312 patients age 22 or older who had an average of between 1 and 2.5 spontaneous bowel movements (SBM) per week.

Treatment lasted for 8 weeks, with patients ingesting a capsule between 9 and 10 p.m. In one treatment group, the device was activated at 6 a.m., and in the other group at about 2 p.m.

The placebo and treatment groups had similar baseline characteristics, except for a longer duration of constipation in the treatment groups (17.9 versus 14.5 years; P = .0253). In an intention-to-treat analysis, the treatment groups were more likely to achieve an increase of one complete SBM per week (39.26% versus 22.15%; P < .0001) and an increase of two complete SBMs per week (22.7% versus 11.41%; P < .0006).

The capsules also improved straining score, stool consistency, and quality of life. There was no significant difference between treatment and placebo groups with respect to bloating or rescue medication use.

The product had few adverse effects. The most common was a vibrating sensation or discomfort (11.0%, versus none in the placebo group).

Dr. Rao expects that the treatment could be widely applicable since many constipation patients don’t gain sufficient benefit from existing treatments, or find side effects intolerable.

Videos may not increase vaccinations in IBD

Article Type

SAN DIEGO – Video and text messaging may not increase the proportion of people with inflammatory bowel disease (IBD) who get influenza vaccinations.

Although patients who received the messages expressed greater intention to get the vaccinations in a trial of the two methods, they didn’t follow through and get the shots, said Keren Appel, MD, a pediatric gastroenterologist at Children’s Hospital of Orange County in Orange, Calif.

“We found there was no difference in the uptake of the influenza vaccine between the two groups,” she said in an interview. Dr. Appel, who participated in the research while at Cedars-Sinai Medical Center in Los Angeles, presented the finding at the annual Digestive Diseases Week® (DDW) 2022.

People with IBD run an increased risk of complications such as infection, bone fractures, and cancer, said Dr. Appel. Previous research has suggested many people with IBD lack understanding or awareness or are skeptical of immunizations.

A previous trial with text-based email reminders did not result in more immunizations, according to Dr. Appel, so she and her colleagues decided to try promoting health prevention with videos. With feedback from patients, they created a series of animations encouraging patients to get influenza, pneumococcal, and zoster vaccinations and screening for bone health and skin cancer.

They randomly assigned 511 to receive videos and 545 patients to receive texts as a control group. After 6 months, 345 patients remained in the text group and 322 remained in the video group. The two groups had similar demographics, health status, and preventive health behaviors. They were mostly educated White women whose IBD was in remission.

The percentage of those who got flu vaccines increased from 59% (for the 2018-2019 season) to 63% (for the 2019-2020 flu season) in the group that watched the videos. However this change did not quite reach statistical significance (P = .07). The change in the text group, from 55% to 57%, was also not significant (P = .23).

The subjects did express more intention to get flu vaccines. The percentage with this intention increased from 59 to 75 in the video group, and from 55 to 72 in the text group. Both changes were statistically significant (P < .001).

Intentions to receive pneumonia and shingles vaccines, and bone and skin cancer screening, were not statistically different between the groups.

The researchers looked at age, immunosuppression, gender, and education to see if these factors could predict who was most likely to get the flu vaccine, but the only significant predictor was having received a previous flu shot.

Dr. Appel speculated that the videos might have been more effective in a more racially diverse, less educated population, or one where fewer people had previously received vaccinations.

“While we didn’t see a difference in this study, I think it opens up a lot of other questions that we can explore and answer,” she said. “It’s possible that patients may not have a one size fits all on their response. Some may respond better to video. Some may respond to text. Some may need more frequent reminders. Some might need to hear it from their doctor directly.”

Session comoderator Alyse Bedell, PhD, an assistant professor of psychiatry and behavioral neuroscience at the University of Chicago, agreed that a different patient population might have responded differently. “A population that may have lower access to educational resources, or has less educational attainment, or may have fewer people in their communities that are already receiving vaccines – those I think are going to be the populations where we’re going to be more likely to see the effects of an intervention like this,” she said in an interview.

Neither Dr. Appel nor Dr. Bedell reported any relevant financial interests. The study was funded by Pfizer.

Adsorbent offers promise for irritable bowel syndrome diarrhea

Article Type

Wed, 05/25/2022 - 17:11

 

– An intestinal adsorbent, polymethylsiloxane polyhydrate (PMSPH), may relieve the diarrhea associated with irritable bowel syndrome (IBS), researchers say.

The adsorbent reduced abdominal pain, improved stool consistency, and won praise from patients, said Yan Yiannakou, MBChB, a consultant in gastroenterology at County Durham and Darlington (England) National Health Service Foundation Trust.

“It’s great to have something new for patients to try,” he told MDEdge. “And it’s great that this treatment is so safe, and easy to use.”

Dr. Yiannakou presented the finding at the annual Digestive Diseases Week® (DDW).

Many people with irritable bowel syndrome find the currently available treatments and diets difficult to use or ineffective.

First developed 30 years ago in Eastern Europe, PMSPH is marketed over the counter in 30 European countries under the name Enterosgel as a treatment for diarrhea, said Dr. Yiannakou. It received conformité européenne (CE) mark in 2011.

Since PMSPH is not adsorbed by the body, it has been approved as a medical device rather than as a drug, said Dr. Yiannakou. Although its manufacturer is not yet marketing it in the United States, websites there are offering it as a dietary supplement for "toxin binding" and "cleansing the gut."*

Since the etiology of IBS is poorly understood, it is also not clear exactly how PMSPH improves IBS symptoms, Dr. Yiannakou said. “I think this is binding a whole range of molecules which are either irritant or induce diarrhea through secretion.” Fat, bile salts, immune chemicals, and bacterial breakdown products are possibilities, he said.

PMSPH’s approval in Europe rests largely on trials for other forms of diarrhea; it did not undergo a high-quality randomized, placebo-controlled trial for IBS, Dr. Yiannakou said.

To fill that gap, he and his colleagues recruited 440 people with IBS, aged 16-75 years, from 28 sites in England. They randomly assigned 219 to receive PMSPH and 221 to receive a placebo for 8 weeks. Following this blinded phase, both groups received PMSPH for another 8 weeks (a phase requested by the patients who helped design the trial). The investigators then followed up with a phone call 8 weeks later to those who responded to the treatment.

The subjects recorded their symptoms in an e-diary and completed questionnaires. Because of COVID-19 constraints imposed after the trial began, the researchers collected some of the data through virtual visits and online questionnaires.

On a U.S. Food and Drug Administration–recommended composite score for abdominal pain and stool consistency, 37.4% of the patients receiving PMSPH were defined as responders versus 24.3% of the patients receiving the placebo, a statistically significant difference.

However, that score does not accurately reflect the main concerns of people with IBS diarrhea, said Dr. Yiannakou. More important is how often they have diarrhea, and by that measure the difference between the placebo and treatment groups was larger.

There were also statistically significant differences in favor of the PMSPH group in separate scores for abdominal pain, stool frequency, bloating, and urgency.

Surveyed between week 5 and week 8, 69% of patients taking PMSPH reported that they were getting adequate relief, compared with 30% of those taking the placebo. Among the responders surveyed 8 weeks after the open-label phase ended, 74% said they were still benefiting from the treatment. And 81% said they were still using PMSPH, even though they had to buy it for themselves.

Only a handful of patients experienced any adverse events, and there were no significant differences in the number of these events between those taking the placebo and those taking PMSPH.

“I think we’re going to be eager to learn which patients that have irritable bowel syndrome would benefit from this particular treatment,” said session comoderator Eric Shah, MD, MBA, director of gastrointestinal motility at Dartmouth University in Hanover, N.H., who was not involved in the study. He also wanted to know how PMSPH compares to similar binding agents on the market.

Session comoderator Nikrad Shahnavaz, MD, an associate professor of medicine in the division of digestive diseases, department of medicine, at Emory University, Atlanta, said his patients complain two binding agents now prescribed for IBS in the United States, cholestyramine and colestipol, cause nausea and vomiting. That could be an advantage for PMSPH, he said. “It’s good to add to your tools.”

Dr. Yiannakou, Dr. Shahnavaz, and Dr. Shah reported no relevant financial interests.

*An earlier version of this article misstated PMSPH's mechanism of action. It is not adsorbed by the body. Additionally, the marketing status of PMSPH was misstated; it is not currently on the U.S. market.

To fill that gap, he and his colleagues recruited 440 people with IBS, aged 16-75 years, from 28 sites in England. They randomly assigned 219 to receive PMSPH and 221 to receive a placebo for 8 weeks. Following this blinded phase, both groups received PMSPH for another 8 weeks (a phase requested by the patients who helped design the trial). The investigators then followed up with a phone call 8 weeks later to those who responded to the treatment.

The subjects recorded their symptoms in an e-diary and completed questionnaires. Because of COVID-19 constraints imposed after the trial began, the researchers collected some of the data through virtual visits and online questionnaires.

On a U.S. Food and Drug Administration–recommended composite score for abdominal pain and stool consistency, 37.4% of the patients receiving PMSPH were defined as responders versus 24.3% of the patients receiving the placebo, a statistically significant difference.

However, that score does not accurately reflect the main concerns of people with IBS diarrhea, said Dr. Yiannakou. More important is how often they have diarrhea, and by that measure the difference between the placebo and treatment groups was larger.

There were also statistically significant differences in favor of the PMSPH group in separate scores for abdominal pain, stool frequency, bloating, and urgency.

Surveyed between week 5 and week 8, 69% of patients taking PMSPH reported that they were getting adequate relief, compared with 30% of those taking the placebo. Among the responders surveyed 8 weeks after the open-label phase ended, 74% said they were still benefiting from the treatment. And 81% said they were still using PMSPH, even though they had to buy it for themselves.

Only a handful of patients experienced any adverse events, and there were no significant differences in the number of these events between those taking the placebo and those taking PMSPH.

“I think we’re going to be eager to learn which patients that have irritable bowel syndrome would benefit from this particular treatment,” said session comoderator Eric Shah, MD, MBA, director of gastrointestinal motility at Dartmouth University in Hanover, N.H., who was not involved in the study. He also wanted to know how PMSPH compares to similar binding agents on the market.

Session comoderator Nikrad Shahnavaz, MD, an associate professor of medicine in the division of digestive diseases, department of medicine, at Emory University, Atlanta, said his patients complain two binding agents now prescribed for IBS in the United States, cholestyramine and colestipol, cause nausea and vomiting. That could be an advantage for PMSPH, he said. “It’s good to add to your tools.”

Dr. Yiannakou, Dr. Shahnavaz, and Dr. Shah reported no relevant financial interests.

Alarming increase in esophageal cancer in middle-aged adults

Article Type

Tue, 05/24/2022 - 10:11

An alarming increase in both esophageal cancer (EC) and the primary precursor lesion for esophageal adenocarcinoma known as Barrett’s esophagus (BE) has been observed among middle-aged adults over the past 5 years, and it’s not because of better or more frequent screening, warn the authors of a new study from Florida.

“We found that the [prevalence of] esophageal cancer and Barrett’s esophagus may have in fact plateaued in the elderly, but there is a concerning increase in their prevalence in middle-aged adults despite the fact that there has been no increase in the use of endoscopy in this population,” Bashar Qumseya, MD, MPH, associate professor of medicine and chief of endoscopy, University of Florida, Gainesville, told a press briefing.

“This should be of great concern to physicians and to patients, and it is our suggestion that maybe we should consider screening middle-aged patients or even those at younger ages for both conditions,” he added.

The study was highlighted during a press briefing in advance of the annual Digestive Disease Week® (DDW).
 

Research network

The analysis was carried out using electronic health records from the OneFlorida Clinical Data Research Network, a database that covers over 40% of residents living in Florida. The researchers identified patients who had been diagnosed with EC or BE between 2012 and 2019. “The primary outcome of interest was the adjusted prevalence of EC and BE in the population,” they stated.

The cohort was categorized by age: those aged 18-44 years (young); those aged 45-64 years (middle-aged), and those older than 65 (elderly). The number of patients included in the database varied by year and ranged from 4,238,884 to 5,411,838 patients per year, the investigators noted. Interestingly, in the most recent year, 2019, more women, at over 57%, were diagnosed with EC than were men.

Over the study interval, the prevalence of EC remained stable among the elderly but nearly doubled among middle-aged patients, from a rate of 49 per 100,000 in 2012 to a rate of 94 per 100,000 in 2019.

Similarly, there was a 50% increase in BE over the same study interval, from 304 per 100,000 in 2012 to 466 per 100,000 in 2019, again in the middle-aged group. The increase in the prevalence of BE was highest in those aged 51-60 years, followed by those aged 61-70 years and then by those aged 41-50.

Data from the same cohort also indicated that the great majority of patients with multiple risk factors for EC or BE – obesity, diet, and gastroesophageal reflux disease – had never undergone endoscopy, “so we can definitely do better,” Dr. Qumseya said. One simple way to “do better” is to offer patients an endoscopy when they undergo their first colonoscopy at the recommended age of 45 years.

“I am not in a position to make the guidelines,”Dr. Qumseya commented. “But we do [already] have guidelines that suggest that patients with multiple risk factors [for EC and BE] be screened, and since we know from our data that this is not happening, I believe that if a patient has multiple risk factors, they should have at least one screening endoscopy at the time of colonoscopy. Otherwise, we are missing a good opportunity to do so, and personally, I think this is something that we should be considering.”

CRC screening: Blood test accuracy compared to colonoscopy

Article Type
Changed
Tue, 05/24/2022 - 10:33

The first prospective study to evaluate the accuracy of a blood test for people being screened for colorectal cancer (CRC) revealed a high sensitivity and specificity.

At 90% specificity, the blood assay (Guardant Health) was 100% sensitive for detecting CRC. At 95% specificity, sensitivity was 88%.

The blood assay detects circulating tumor DNA from cancer in the bloodstream, which is then analyzed for multiple factors, including cancer genetics and methylation.

Lead author Paloma Peinado, MD, a medical oncologist at HM Hospitales, Madrid, and colleagues, called the results similar to those seen with noninvasive, stool-based testing, noting that the “sensitivity and specificity of the blood-based test reached clinically significant thresholds.”

“The reported performance, combined with a more acceptable mode of testing, suggests that this blood-based test may be a viable CRC screening option,” they added.

The study was presented at Digestive Disease Week® (DDW) 2022, held virtually and in San Diego.

Dr. Peinado and colleagues studied 557 people who agreed to have blood drawn at the time of their colonoscopy. They enrolled participants at four hospitals in Spain.

One-third of participants (33%) who sought CRC screening were at average risk. Of the remainder, 49% were symptomatic, 11% had a positive family history of CRC, 6% had a positive stool-based test result, and 1% presented for colonoscopy for other reasons.

The prospective observational study included people age 45-84 years. The median age of participants was 55 years, and just over half (52%) were women.

The prevalence rate of colorectal adenocarcinoma was 2.6%. Eight patients had stage I cancer, three had stage II cancer, two had stage III cancer, and two had stage IV cancer.

The study was designed to follow patients for 1 year after screening. To date, 14% of participants have reached this point.

Not a general population screening study

“We definitely we need more studies like this,” said Barbara H. Jung, MD, chair of the department of medicine at the University of Washington, Seattle, when asked to comment on the study.

“We need to find other ways to detect colorectal cancer early, to enhance the screening, and to broaden it to a larger population who may not be amenable to the other techniques.”

Dr. Jung added a caveat that the study population included people at a higher risk for CRC. Therefore, she said, it was a screening study but not a general population, average-risk screening study.

However, she said, “that does not mean that this could not be optimized in the future.”  

Ideally, we need tests for every application, including people who are asymptomatic, Dr. Jung said.

Dr. Peinado reports no relevant financial relationships. Some of the study authors are employees of Guardant Health. Dr. Jung reports no relevant financial relationships.

PI-based DAAs appear safe in decompensated patients

Article Type

Wed, 05/25/2022 - 10:58

 

– An analysis of a large, international cohort suggests that treatment with protease-inhibitor (PI)–based direct-acting antivirals (DAAs) may be safe for patients with hepatitis C virus (HCV) with cirrhosis and early-stage liver decompensation.

The study relied on data from the REAL-C registry, including 935 patients treated with oral DAAs at 27 centers in the U.S., Europe, and Asia Pacific countries. The researchers compared efficacy and tolerability outcomes from PI-based and non PI-based DAA regimens in patients deemed to have decompensated HCV cirrhosis.

The findings were encouraging. “It is something important because currently we are short of treatments for decompensated HCV patients. If the tolerability is similar, we perhaps should not withhold [PI] treatment for these patients that sometimes need them the most,” said Yu Jun Wong, MD, who presented the study at the annual Digestive Disease Week® (DDW). Dr. Wong is a second-year consultant at Changchi General Hospital in Singapore.

“I think it was a very interesting study and something that needed to be done. It was encouraging that patients who did have some level of decompensated cirrhosis did not worsen compared to those who were on a non PI-based therapy,” said Meena Bansal, MD, who comoderated the session where the research was presented.

However, the study was limited by some uncertainty around the definition of decompensation among the study participants. During the Q&A session, audience members questioned whether patients categorized as decompensated were truly decompensated at the time of treatment initiation. Dr. Bansal noted, for example, that a patient might experience a variceal bleed in the context of heavy alcohol consumption, and therefore be considered decompensated, but might stop drinking afterward with a reduction in portal hypertension and recovery of liver function. “So it would be important to know if they were still decompensated at the time they initiated therapy. If that was the case, then these results are more promising,” said Dr. Bansal.

Despite these limitations, the study is good news. “If you do not have access to non-PI based therapy, you might feel a little bit more secure starting a PI-based therapy, particularly the second generation PI-based therapies, if they’re at least on the earlier side of that decompensation scale. But it’s still unclear in true decompensated Child’s B or C whether or not PI-based therapy would have the same results,” said Dr. Bansal.

Dr. Wong acknowledged the limitation that the study doesn’t apply to more severely decompensated patients. “Whether it remains safe in patients with higher Child-Pugh scores is hard to extrapolate at this point of time. We still need to look further into the data,” said Dr. Wong.

Still, the results offer hope to physicians and patients who might find themselves in difficult circumstances. “If you’re resource limited, and you don’t even have access to transplant, these findings suggest that early decompensated patients may benefit from PI-based therapy. If I say to the patient, there’s a chance this could make you worse, but there’s a chance this could make you better, [this is an option] as long as the patient is aware of the possible outcomes,” said Dr. Bansal.

The study included patients with a history of ascites, variceal bleeding, jaundice, or hepatic encephalopathy 6 months before treatment with DAA, or baseline measures of Child-Turcotte-Pugh (CTP) score ≥7 or Model of End-Stage Liver Disease (MELD) score >10. The analysis included data between 2014 and 2021.

The mean age was 64, and 59.6% of participants were male. Overall, 70.8% had genotype 1, and 32% were treatment experienced. In total, 45.2% were treated with PI-based DAAs.

The PI cohort was older (64.6 versus 62.7; P = .01), and more likely to have genotype 1 (87.2% versus 56.3%; P < .001) and chronic renal disease (64.0% vs. 53.9%; P = .001).

The two groups had similar rates of sustained virologic response at 12 and 24 weeks, as well as similar rates of significant improvement or significant worsening, suggesting similar tolerability. There was a lower frequency of liver decompensation in the PI group at 12 weeks (4.4% vs. 7.9%; P = .04) and a trend at 24 weeks (8.8% versus 12.6%; P = .08).

Another limitation of the study is the potential for bias due to its retrospective nature.

Dr. Wong has been an invited speaker for AbbVie and Gilead. Dr. Bansal has no relevant financial disclosures.

The study relied on data from the REAL-C registry, including 935 patients treated with oral DAAs at 27 centers in the U.S., Europe, and Asia Pacific countries. The researchers compared efficacy and tolerability outcomes from PI-based and non PI-based DAA regimens in patients deemed to have decompensated HCV cirrhosis.

The findings were encouraging. “It is something important because currently we are short of treatments for decompensated HCV patients. If the tolerability is similar, we perhaps should not withhold [PI] treatment for these patients that sometimes need them the most,” said Yu Jun Wong, MD, who presented the study at the annual Digestive Disease Week® (DDW). Dr. Wong is a second-year consultant at Changchi General Hospital in Singapore.

“I think it was a very interesting study and something that needed to be done. It was encouraging that patients who did have some level of decompensated cirrhosis did not worsen compared to those who were on a non PI-based therapy,” said Meena Bansal, MD, who comoderated the session where the research was presented.

However, the study was limited by some uncertainty around the definition of decompensation among the study participants. During the Q&A session, audience members questioned whether patients categorized as decompensated were truly decompensated at the time of treatment initiation. Dr. Bansal noted, for example, that a patient might experience a variceal bleed in the context of heavy alcohol consumption, and therefore be considered decompensated, but might stop drinking afterward with a reduction in portal hypertension and recovery of liver function. “So it would be important to know if they were still decompensated at the time they initiated therapy. If that was the case, then these results are more promising,” said Dr. Bansal.

Despite these limitations, the study is good news. “If you do not have access to non-PI based therapy, you might feel a little bit more secure starting a PI-based therapy, particularly the second generation PI-based therapies, if they’re at least on the earlier side of that decompensation scale. But it’s still unclear in true decompensated Child’s B or C whether or not PI-based therapy would have the same results,” said Dr. Bansal.

Dr. Wong acknowledged the limitation that the study doesn’t apply to more severely decompensated patients. “Whether it remains safe in patients with higher Child-Pugh scores is hard to extrapolate at this point of time. We still need to look further into the data,” said Dr. Wong.

Still, the results offer hope to physicians and patients who might find themselves in difficult circumstances. “If you’re resource limited, and you don’t even have access to transplant, these findings suggest that early decompensated patients may benefit from PI-based therapy. If I say to the patient, there’s a chance this could make you worse, but there’s a chance this could make you better, [this is an option] as long as the patient is aware of the possible outcomes,” said Dr. Bansal.

The study included patients with a history of ascites, variceal bleeding, jaundice, or hepatic encephalopathy 6 months before treatment with DAA, or baseline measures of Child-Turcotte-Pugh (CTP) score ≥7 or Model of End-Stage Liver Disease (MELD) score >10. The analysis included data between 2014 and 2021.

The mean age was 64, and 59.6% of participants were male. Overall, 70.8% had genotype 1, and 32% were treatment experienced. In total, 45.2% were treated with PI-based DAAs.

The PI cohort was older (64.6 versus 62.7; P = .01), and more likely to have genotype 1 (87.2% versus 56.3%; P < .001) and chronic renal disease (64.0% vs. 53.9%; P = .001).

The two groups had similar rates of sustained virologic response at 12 and 24 weeks, as well as similar rates of significant improvement or significant worsening, suggesting similar tolerability. There was a lower frequency of liver decompensation in the PI group at 12 weeks (4.4% vs. 7.9%; P = .04) and a trend at 24 weeks (8.8% versus 12.6%; P = .08).

Another limitation of the study is the potential for bias due to its retrospective nature.

Bacterial cocktail, spores counter recurrent C. diff

 

– A novel combination of eight human commensal bacteria has shown efficacy in preventing recurrent Clostridioides difficile infections in high-risk populations. The cocktail of bacterial strains (VE303), produced under tightly-controlled conditions, is delivered in powdered form over a period of 14 days.

The approach, sponsored by Vedanta Biosciences, is one of several efforts to use carefully defined microbial populations instead of fecal microbiota transplantation (FMT) to treat or prevent C. diff infections.

The key issue is that not all of the bacteria found in FMTs are needed to provide a therapeutic effect, according to Thomas Louie, MD, professor of medicine at the University of Calgary (Alta.). “You don’t need all the bugs. You don’t need raw [stool]. You can take only the good parts,” said Dr. Louie, who presented the results of the phase 2 study at the annual Digestive Disease Week® (DDW). In fact, FMT carries the risk of infection of pathogenic bacteria.

The strains found in VE303 were consistently identified in patients’ microbiota following successful FMTs, though they were absent before the transplant. Animal and human studies then showed that the microbes could repopulate microbiota.

Among 78 patients included in the efficacy analysis of the study, after 8 weeks, 13.8% of the VE303 group experienced a recurrent C. diff infection, versus 45.5% of the placebo group, amounting to more than an 80% reduction in risk (odds ratio, 0.192; P = .0077). Adverse events were mild and similar across both groups, with no treatment-related serious adverse events reported.

The same session included a post hoc analysis of a phase 3 study sponsored by Seres Therapeutics, which showed that the company’s oral product SER-109, composed of purified Firmicutes spores, reduced the risk of recurrent C. diff infection after 8 weeks compared to placebo (12.4% versus 39.8%; P < .001).

The new analysis examined short-, medium-, and branch-chained fatty acids in patient stools. After just 1 week of treatment, there was an increase in the short-chain fatty acid butyrate and medium-chain fatty acids valerate and hexanoate. They continued to be higher in weeks 2 and 8 in the treatment arm. The results suggest that increased fatty acid production might boost clinical outcomes, according to Kevin Litcofsky of Seres, who presented the results.

Both approaches have potential, according to Melinda Engevik, PhD, who comoderated the session where the study was presented. “I think that they’re both interesting ideas. The spores [from Seres], I think, are going to be better at passing through the stomach and a little bit more resistant, but then they have to germinate and engraft, whereas if you give the lyophilized bacteria [from Vedanta], you might lose some more, but they’re already primed and ready to go. So I think they’re both very different approaches, but the data from both seem to support that they worked and probably in different ways,” said Dr. Engevik, assistant professor at the Medical University of South Carolina, Charleston.

“Patients that have recurrent [C. diff], they are desperate to be able to break the cycle of recurrence. I think that they’ve shown a lot of safety with this, which is an issue for FMT. Both of the talks seemed like there is a path moving forward to help those patients. I was encouraged,” said Dr. Engevik.

Comoderator Anoop Kumar, PhD, assistant professor of gastroenterology and hepatology at University of Illinois, Chicago, agreed and noted the advantage of such treatments over FMT during the COVID-19 pandemic, which has disrupted FMT delivery.

Previous studies have looked at probiotics, but results so far have been mixed, said Dr. Engevik. She suspects these two approaches, containing more bacterial strains, are likely to have better success. “I think you really have to have a complex gut microbiota community, at least minimally complex, to be able to get the effects. I think it’s the wave of the future,” she said.

Dr. Engevik also suggested that the benefits might not stop at C. diff. She highlighted research in other gastrointestinal diseases such as inflammatory bowel disease, and even efforts underway to enhance responses to checkpoint inhibitors in the treatment of cancer. “Gut microbes are master regulators, so they have these wide-reaching effects. I think that a lot of human health will be started to be targeted by looking at the gut microbiota,” she said.

Dr. Louie also highlighted the potential for more applications. “C. diff is low-hanging fruit. I think these bugs will have some usefulness for [irritable bowel syndrome]. I’ve transplanted some patients with IBS and it seemed to work. I haven’t had time to design and do an IBS trial, but the future is these bugs.”

Dr. Louie also participated in the Seres study. He has been on the advisory board for Vedanta, Seres, Finch Therapeutics, and Artugen Therapeutics. Dr. Engevik and Dr. Kumar have no relevant financial disclosures.

Treatment for alcohol abuse reduces hepatitis readmission

– Treating people with alcoholic hepatitis for alcohol abuse may reduce their risk of hospital readmission, researchers reported.

In a retrospective analysis of nationwide data, 7.83% of those patients who received psychotherapy, counseling, or drug treatment for alcohol abuse were readmitted within 30 days, versus 11.67% of those who did not receive these kinds of treatment.

The finding lends support to the argument that hospitals should invest more in the treatments, despite the complexities involved.

“It takes a multidisciplinary approach, starting from the physician or the health care provider along with the pharmacists, the behavioral health specialists, or a psychiatrist or psychologist, along with case management as well,” said Harleen Chela, MD, a third-year resident at the University of Missouri in Columbia. She presented the findings at the annual Digestive Disease Week® (DDW).

The researchers started with the premise that patients with alcoholic hepatitis can prevent the condition from worsening by abstaining from alcohol. To see whether interventions aimed at encouraging that abstention could prevent readmissions, Dr. Chela and colleagues analyzed data on readmissions for the first 11 months of the year 2018.

They included patients who were at least 18 years of age and who had a nonelective admission with a principal diagnosis of alcohol abuse.

Using procedure codes, they compared those patients given psychotherapy (including cognitive behavioral therapy), formal inpatient counseling, and drug treatment for alcohol abuse to those who didn’t. Then they counted how many patients were readmitted within 30 days.

They found records of 45,617 patients admitted for alcoholic hepatitis of whom 1,552 received treatment for alcohol abuse and 44,065 did not.

They did not find any significant difference between the two groups in demographics, income, or insurance status.

Adjusting for such factors, the researchers found that people who received alcohol abuse treatment were 64% as likely to be readmitted as were those who did not (hazard ratio, 0.64; 95% confidence interval, 0.46-0.91; P = 0.01).

If alcohol abuse treatment is so effective, why isn’t it routine? “It’s not always feasible to implement this, on the inpatient side, because it takes more than a day or two just to get some of these things put in place,” Dr. Chela told this news organization.

They did find that people were more likely to get treatment for alcohol abuse if they were admitted to a hospital in a big city rather than a small town and if their hospital was owned by private investors rather than by a not-for-profit organization or the government.

“Larger hospitals and private sector institutions have more access to resources and money to have those kinds of systems in place for the patients,” said Dr. Chela.

She became interested in the issue at her hospital when she noticed that patients with alcoholic hepatitis were not getting behavioral counseling. “The inpatient load in the behavioral health side is so much that they don’t have time for these kinds of consults,” she said. “That’s one of the challenges: A shortage of behavioral specialists like psychiatrists.”

And hospitals tend to focus on treating conditions that threaten their patients’ lives in the short term. “Someone who has a heart attack or a gastrointestinal bleed – there’s more focus on resources for those kinds of patients,” she said.

Virginia Commonwealth University in Richmond provides alcohol abuse treatment to patients with alcoholic hepatitis partly using telehealth, said Richard Sterling, MD, MSc, chief of hepatology, who was not involved in the study. “For people who live too far away, don’t have transportation, or have other health disparities, we now have technology and mechanisms to keep them engaged in care,” he told this news organization. “We’re doing a lot of Zoom visits.”

Dr. Chela and colleagues also found that those who got alcohol abuse treatment were less likely to be discharged to a skilled nursing facility or to home health. The data couldn’t give the researchers a definitive reason for this, but Dr. Chela speculated that the patients who received treatment for alcohol abuse stayed longer in the hospital and may have been in better shape when they were discharged.

The U.S. health care system doesn’t necessarily provide incentives to keep patients healthy, Dr. Sterling said. “Hospital systems make money off of filling beds, and providing a lot of inpatient care and hospital days,” he said. “That may be not necessarily congruent with a health system that is supposed to provide health for these covered lives.”

Neither Dr. Chela nor Dr. Sterling reported any relevant financial relationships.
