Irisin Shows Potential as Alzheimer’s Disease Biomarker
, according to investigators.
Irisin, a hormone released by muscles during physical exercise, also negatively correlated with Clinical Dementia Rating Scale Sum of Boxes (CDR-SOB) in female patients, pointing to a sex-specific disease phenomenon, reported by co-lead authors Manuela Dicarlo, PhD, and Patrizia Pignataro, MSc, of the University of Bari “A. Moro,” Bari, Italy, and colleagues.
Regular physical exercise can slow cognitive decline in individuals at risk for or with Alzheimer’s disease, and irisin appears to play a key role in this process, the investigators wrote in Annals of Neurology. Previous studies have shown that increased irisin levels in the brain are associated with improved cognitive function and reduced amyloid beta levels, suggesting the hormone’s potential as a biomarker and therapeutic target for Alzheimer’s disease.
“Based on the protective effect of irisin in Alzheimer’s disease shown in animal and cell models, the goal of the present study was to investigate the levels of irisin in the biological fluids of a large cohort of patients biologically characterized according to the amyloid/tau/neurodegeneration (ATN) scheme of the National Institute on Aging–Alzheimer’s Association (NIA-AA),” Dr. Dicarlo and colleagues wrote. “We aimed to understand whether there may be variations of irisin levels across the disease stages, identified through the ATN system.”
Lower Levels of Irisin Seen in Patients With Alzheimer’s Disease
The study included 82 patients with Alzheimer’s disease, 44 individuals with mild cognitive impairment (MCI), and 20 with subjective memory complaints (SMC). Participants underwent comprehensive assessments, including neurological and neuropsychological exams, nutritional evaluations, MRI scans, and routine lab tests. Cognitive impairment severity was measured using the CDR-SOB and other metrics.
Blood and CSF samples were collected from all patients, the latter via lumbar puncture. These samples were analyzed for irisin levels and known Alzheimer’s disease biomarkers, including Abeta42, total tau (t-tau), and hyperphosphorylated tau (p-tau).
Mean CSF irisin levels were significantly lower among patients with Alzheimer’s disease than those with SMC (0.80 vs 1.23 pg/mL; P < .0001), and among those with MCI vs SMC (0.95 vs 1.23 pg/mL; P = .046). Among patients with Alzheimer’s disease, irisin levels were significantly lower among women than men (0.70 vs 0.96 pg/mL; P = .031).
Further analyses revealed positive correlations between CSF irisin level and Abeta42 in both males (r = 0.262; P < 005) and females (r = 0.379; P < .001). Conversely, in female patients, a significant negative correlation was found between CSF irisin level and CDR-SOB score (r = −0.234; P < .05).
Although a negative trend was observed between CSF irisin and total tau (t-tau) in the overall patient population (r = −0.144; P = 0.082), and more notably in female patients (r = −0.189; P = 0.084), these results were not statistically significant.
Plasma irisin levels were not significantly correlated with any of the other biomarkers.
Clinical Implications
This study “verifies that irisin levels do have a relationship to the Alzheimer’s disease process,” said Dylan Wint, MD, director of Cleveland Clinic Lou Ruvo Center for Brain Health, Las Vegas.
In a written comment, Dr. Wint speculated that measuring irisin levels could theoretically help individualize physical exercise routines designed to combat cognitive decline.
“For example, maybe someone who is exercising but has a low irisin level would need to change the type of exercise they’re doing in order to optimally protect their brain health,” he said. “Or maybe they won’t get the same benefits for brain health as someone whose irisin shoots up every time they walk a flight of stairs.”
It’s “near-impossible to tell,” however, if irisin will be employed in clinical trials or real-world practice, he added.
“I don’t see this being a highly useful serum biomarker for Alzheimer’s disease itself because other serum biomarkers are so far ahead and have more face validity,” Dr. Wint said.
The route of collection could also cause challenges.
“In the United States, CSF-based biomarkers can be a difficult sell, especially for serial testing,” Dr. Wint said. “But we have usable serum biomarkers for Alzheimer’s disease only because we have had CSF biomarkers against which to evaluate them. They may develop a way to evaluate this in the serum.”
Dr. Dicarlo and colleagues suggested that more work is needed to determine the ultimate value of irisin measurement.“The true ability of irisin to represent a biomarker of disease progression and severity remains to be further investigated,” they concluded. “However, our findings might offer interesting perspectives toward the potential role of irisin in the modulation of AD pathology and can guide the exploration of medication targeting the irisin system.”
The study was supported by Regione Puglia and CNR for Tecnopolo per la Medicina di Precisione, CIREMIC, the University of Bari, and Next Generation EU. The investigators and Dr. Wint disclosed no conflicts of interest.

Gestational Rhinitis: How Can We Manage It?
PARIS — Allergic comorbidities such as asthma and rhinitis are common among pregnant women. During the 19th French-speaking Congress of Allergology, Dario Ebode, MD, otolaryngologist and cervicofacial surgeon at Hôpital de la Conception in Marseille, France, described gestational rhinitis and detailed its management.
A Hormonal Rhinitis
The prevalence of rhinitis during pregnancy ranges from 18% to 30%, whether it is pre-existing (eg, allergic or infectious) or newly diagnosed. About half of the cases of pre-existing rhinitis worsen during pregnancy, leading to gestational rhinitis, which has a prevalence of approximately 22%.
“The latter is characterized by its onset in the 2nd or 3rd trimester, a duration of > 6 weeks, an absence of associated allergic symptoms, and complete spontaneous resolution 2-3 weeks after delivery,” said Dr. Ebode.
Uncertainties about the pathophysiology of gestational rhinitis, a “hormonal rhinitis,” remain, he added. Beta-estradiol and progesterone hormones lead to an increase in H1 histamine receptors on epithelial and endothelial cells, which promotes the migration or degranulation of eosinophils.
Management
While gestational rhinitis is benign, its symptoms can still be bothersome and can be relieved. In addition to dietary and hygienic (nasal irrigation with large volumes) measures and allergen avoidance, local treatments include nasal corticosteroids, possibly combined with antihistamines, and systemic antihistamines. “During pregnancy, nasal corticosteroids, oral antihistamines [excluding azelastine hydrochloride before 10 weeks], and ipratropium bromide are allowed,” said Dr. Ebode. Regarding sprays that combine corticosteroids and antihistamines, the combination of mometasone furoate and olopatadine is possible but not the combination of azelastine hydrochloride and fluticasone propionate before 10 weeks.
Finally, oral vasoconstrictors (which are found in many over-the-counter medications) should be avoided, as should Kenacort (triamcinolone acetonide), “which also has no place in women outside of pregnancy due to an unfavorable risk-benefit balance in rhinitis,” said Dr. Ebode. Allergen immunotherapy plans should be postponed after delivery.
Dr. Ebode reported a financial relationship with Zambon.

The Push to Get More People Into Long COVID Studies
When Ezra Spier was diagnosed with long COVID in late 2022, his main symptom, postexertional malaise, caused fatigue so severe that it forced him to quit his job as a technology entrepreneur. Since then, it’s been a tough road for Spier, 37, who said he wouldn’t wish his hellish condition on anyone.
Last spring, he enrolled in a clinical trial of a new long COVID therapy at Stanford University, and he’s about to start another at the University of California, San Francisco.
For Spier, who lives in Oakland, California, being part of the clinical trials connected him with people dealing with similar health issues while also moving the needle toward better treatments for everyone. Yet many potential participants are unaware that these clinical trials exist. Clinical trial researchers also express frustration over the challenge of enrolling participants.
That’s why Spier created a new website to help match long COVID patients with clinical trials that can help.
“I wanted a way to make long COVID clinical trials more accessible to the general public,” he said. Spier’s website, aptly named Long Covid Studies, launched in March. The site already includes details from about 550 trials globally and, in the future, will include many more.
It’s Not the Number of Studies, It’s Navigating Them
In all, nearly 9300 long COVID trials are listed on ClinicalTrials.gov. But many patients find the site difficult to navigate, said David F. Putrino, PhD, who runs the long COVID clinic at Mount Sinai Health System in New York City. He said Spier’s website helps make trials easier for patients to manage in ways that remove the enrollment challenges.
“Ezra’s platform pulls data from ClinicalTrials.gov and puts it into a space that’s much easier for patients to manage,” said Dr. Putrino. The site only includes the most relevant information, such as the study location, eligibility, and purpose and how to sign up.
Another of Spier’s goals is to make the process easier for patients who are already marginalized and often excluded from the healthcare system. Long COVID disproportionately impacts people in minority ethnic groups and women, as well as those who are impoverished or live in rural areas.
According to the National Institutes of Health (NIH), 1 in 4 patients with severe long COVID-19 are Black or Hispanic whereas only 1 in 7 are White. Yet participation by White persons in clinical trials is much higher overall: 77% of participants are White, compared with only 14% for Black persons and 15% for Hispanic persons. Without more balanced representation, research becomes skewed and less accurate, said Grace McComsey, MD, who leads one of the 15 nationwide long COVID centers funded by the federal RECOVER (Researching COVID to Enhance Recovery) Initiative in Cleveland.
Websites that are easier for the layperson to access would allow for wider participation, said McComsey.
Too Many Barriers to Entry
A study published in the Journal of Applied Gerontology found that transportation plays an outsized role in influencing study participation, which may also lead to less diverse participation.
Decentralized trials — in which participants receive therapy at home — also make enrolling in clinical trials easier for marginalized patients and those too sick to make it to a research center, said Dr. Putrino. Research published recently in The American Journal of Medicine demonstrated that for many patients, remote studies are the future of COVID research. The study, focusing on the efficacy of Paxlovid, recruited patients living in the 48 contiguous US states. Participation was entirely remote.
“We need to have more consideration for bedbound and housebound patients in our research,” said Dr. Putrino. “Some people don’t have the ability to show up to a prestigious university to take part in an academic trial.”
Dr. Putrino and colleagues at Yale School of Medicine’s Yale COVID Recovery Study plan to release a paper in the near future on the methodology for running decentralized or remote studies that could provide guidance for researchers elsewhere.
Decentralized studies serve a larger audience, but they’re also more expensive and cost has plagued long COVID research from the start, said Michael Peluso, MD, an assistant research professor of infectious medicine at UCSF School of Medicine, University of California, San Francisco.
“You need to have a staff in place that’s trained to do home visits in order to conduct remote trials,” Dr. Peluso said, adding that his biggest challenge has been connecting patients to appropriate clinical trials.
Individual eligibility has been an ongoing issue. For example, Dr. Peluso’s current trials are testing monoclonal antibodies — antibodies produced by cloning unique white blood cells to target viral persistence, which is thought to be a cause of long COVID. Only patients who were infected with certain variants of acute COVID are eligible because of the antibodies needed to target SARS-CoV-2 spike proteins.
“This can lead to a lot of frustration among patients who might think they can participate, but aren’t eligible,” said Dr. Peluso.
Long Fight for Better Long COVID Research
For Spier, one of the hardest parts of his health issues and lack of energy is that they have sharply curtailed his social interactions with friends and colleagues.
He has channeled his energies into researching new treatments that could potentially improve his symptoms. That research is partly what drove him to create the Long Covid Studies website.
His goal is still to help others with long COVID find trials that can improve their symptoms as well. The more people who participate, the closer scientists will come to providing effective treatments for everyone, he said.
“For all my frustrations, we’re still at the forefront of science globally,” he said. “And if we have the level of funding the NIH is equipped to provide, we can show the world what’s possible with long COVID research.”

“Ezra’s platform pulls data from ClinicalTrials.gov and puts it into a space that’s much easier for patients to manage,” said Dr. Putrino. The site only includes the most relevant information, such as the study location, eligibility, and purpose and how to sign up.
Another of Spier’s goals is to make the process easier for patients who are already marginalized and often excluded from the healthcare system. Long COVID disproportionately impacts people in minority ethnic groups and women, as well as those who are impoverished or live in rural areas.
According to the National Institutes of Health (NIH), 1 in 4 patients with severe long COVID-19 are Black or Hispanic whereas only 1 in 7 are White. Yet participation by White persons in clinical trials is much higher overall: 77% of participants are White, compared with only 14% for Black persons and 15% for Hispanic persons. Without more balanced representation, research becomes skewed and less accurate, said Grace McComsey, MD, who leads one of the 15 nationwide long COVID centers funded by the federal RECOVER (Researching COVID to Enhance Recovery) Initiative in Cleveland.
Websites that are easier for the layperson to access would allow for wider participation, said McComsey.
Too Many Barriers to Entry
A study published in the Journal of Applied Gerontology found that transportation plays an outsized role in influencing study participation, which may also lead to less diverse participation.
Decentralized trials — in which participants receive therapy at home — also make enrolling in clinical trials easier for marginalized patients and those too sick to make it to a research center, said Dr. Putrino. Research published recently in The American Journal of Medicine demonstrated that for many patients, remote studies are the future of COVID research. The study, focusing on the efficacy of Paxlovid, recruited patients living in the 48 contiguous US states. Participation was entirely remote.
“We need to have more consideration for bedbound and housebound patients in our research,” said Dr. Putrino. “Some people don’t have the ability to show up to a prestigious university to take part in an academic trial.”
Dr. Putrino and colleagues at Yale School of Medicine’s Yale COVID Recovery Study plan to release a paper in the near future on the methodology for running decentralized or remote studies that could provide guidance for researchers elsewhere.
Decentralized studies serve a larger audience, but they’re also more expensive and cost has plagued long COVID research from the start, said Michael Peluso, MD, an assistant research professor of infectious medicine at UCSF School of Medicine, University of California, San Francisco.
“You need to have a staff in place that’s trained to do home visits in order to conduct remote trials,” Dr. Peluso said, adding that his biggest challenge has been connecting patients to appropriate clinical trials.
Individual eligibility has been an ongoing issue. For example, Dr. Peluso’s current trials are testing monoclonal antibodies — antibodies produced by cloning unique white blood cells to target viral persistence, which is thought to be a cause of long COVID. Only patients who were infected with certain variants of acute COVID are eligible because of the antibodies needed to target SARS-CoV-2 spike proteins.
“This can lead to a lot of frustration among patients who might think they can participate, but aren’t eligible,” said Dr. Peluso.
Long Fight for Better Long COVID Research
For Spier, one of the hardest parts of his health issues and lack of energy is that they have sharply curtailed his social interactions with friends and colleagues.
He has channeled his energies into researching new treatments that could potentially improve his symptoms. That research is partly what drove him to create the Long Covid Studies website.
His goal is still to help others with long COVID find trials that can improve their symptoms as well. The more people who participate, the closer scientists will come to providing effective treatments for everyone, he said.
“For all my frustrations, we’re still at the forefront of science globally,” he said. “And if we have the level of funding the NIH is equipped to provide, we can show the world what’s possible with long COVID research.”

CAR T for B-ALL: Game Changer For Young Patients?
It’s becoming more common for patients with less severe disease to undergo the treatment, often bypassing hematopoietic stem cell transplantation (HSCT), and survival is on the rise.
From 2018 to 2022, the percentage of patients in an international cohort who had disease burden of ≥50% fell from 18% to 4%, researchers reported at the annual meeting of the American Society of Clinical Oncology (ASCO) in Chicago. Median relapse-free survival in patients who didn’t undergo post-infusion HSCT grew from 18 months in 2018 to 27 months in 2020. It was not estimable in 2021.
“This introduction of the therapy is changing the treatment landscape of how we look at refractory B-ALL, where the standard of care previously would be to proceed to transplant. This therapy is actually reducing the use of transplant, which has lots of morbidity and mortality associated with it,” Texas Children’s Cancer Center hematologist-oncologist Rayne H. Rouce, MD, who led the study, said in an interview.
Tisagenlecleucel received Food and Drug Administration approval in 2017, said Nirali N. Shah, MD, MHSc, head of the Pediatric Oncology Branch’s Hematologic Malignancies Section at the National Cancer Institute, in an interview. Dr. Shah is familiar with the study findings but didn’t take part in the research.
Remission rates have been around 60%-70%, Dr. Shah said, although that rate is “likely higher” now because of gains in experience and improvement in disease burden prior to therapy.
The new findings fill a knowledge gap about real-world outcomes since a lot of the prior data was based on investigational CAR T-cell products, she said.
The noninterventional, prospective, longitudinal study, funded by tisagenlecleucel manufacturer Novartis, tracked 974 patients up to age 25 who received tisagenlecleucel in the United States, Canada, Korea, and Taiwan.
The study found that between 2018 and 2022:
- The percentage of patients who received treatment while in morphological complete remission grew from 34% to 51%.
- The percentages who were in third or greater relapse fell from 14% to 2%.
- The percentages undergoing ≥1 HSCT before tisagenlecleucel infusion fell from 37% to 15%.
- Overall, 34.5% of 911 patients received post-infusion HSCT.
In the big picture, the findings suggest that the therapy can be considered more than “a last resort for patients in a second or greater relapse or who are refractory,” Dr. Rouce said. By offering CAR T-cell therapy to earlier-stage patients, she said, “when they’re less sick, when they have less comorbidities, and when their organs are functioning better, we could potentially save them from having to go on to a transplant.”
Dr. Shah said the findings indicate that “a substantial number of patients are surviving. It’s remarkable actually. Prior to tisagenlecleucel, patients had dismal outcomes from standard chemotherapy.”
She added that the study suggests “providers are getting much more comfortable with getting their patients in the best shape prior to getting CAR T-cell therapy. Outcomes are improving as providers expand the use of CAR T-cell therapy to patients who are less heavily pretreated and have lower disease burden.”
Moving forward, “at some point there will likely be a plateau in terms of how good the outcomes can be.” And there will be discussion of the role of HSCT.
“We’ll figure out some of the nuances about which patients need transplants and which can avoid them. But curative potential is growing. With or without transplant, this is ultimately going to lead to a much higher fraction of patients being cured who previously would not have been cured,” she said. “That’s the bottom line.”
As for adverse effects, Dr. Shah said “disease burden has a pretty direct relationship with side effects and toxicities. If you have more disease, you have more severe side effects.”
Reducing disease burden will reduce side effects, she said. Also, “we’re getting a lot better at managing these toxicities. Eliminating some of the more toxic chemotherapy through earlier use of CAR T-cells in chemotherapy-refractory patients may well help reduce therapy burden and improve long-term survival outcomes, she added.
As for cost, drugs.com reports that the therapy runs to more than $612,000 per infusion. But Dr. Shah said insurers are covering the treatment. She added that there are efforts to expand the indication so CAR T-cell therapy can be used earlier in patients who are chemotherapy-refractory.

FROM ASCO 2024
Cystic Fibrosis Patients Also Experience Poor Sleep, Fatigue, Depression
Non-respiratory symptoms including poor sleep, fatigue, pain, anxiety, and depressive symptoms were prevalent among adults with cystic fibrosis (AwCF) and persisted after 1 year of follow-up, based on data from more than 200 individuals in a study presented at the American Thoracic Society (ATS) 2024 International Conference.
“People with cystic fibrosis have qualitatively reported burden from extrapulmonary symptoms that were not being addressed by their health care providers; this is the first study to examine these symptoms concurrently in a large sample over time,” said lead author Kristin A. Riekert, PhD, of Johns Hopkins University, Baltimore, in an interview.
Previous cross-sectional studies have shown a high prevalence of poor sleep quality, fatigue, pain, depression, and anxiety among AwCF, but longitudinal data showing the persistence of symptoms are lacking, Dr. Riekert and colleagues noted in their abstract.
Sleep Quality, Anxiety, and Other Assessments
The researchers recruited a total of 236 AwCF aged 18 years and older from two cystic fibrosis (CF) centers between April 2021 and August 2022. They examined the prevalence of poor sleep quality, fatigue pain, depression, and anxiety in AwCF on the basis of five assessments: At baseline and at 3, 6, 9, and 12 months.
Participants were assessed via an online survey using the Fatigue Severity Scale (cutoff, > 4), Pittsburgh Sleep Quality Index (cutoff, > 5), Patient Health Questionnaire (cutoff, > 9), Generalized Anxiety Disorder (cutoff, > 9), and PROMIS Pain Intensity (cutoff, > 50 T score). Chronic symptoms were defined as positive scores on four or more assessments for individuals who completed four or five time-point assessments. The mean age of the participants was 37 years, 52% were women, 95% were non-Hispanic White, and 86% had been prescribed CF modulator therapy.
Overall, 49% of participants met the criteria for chronic poor sleep quality, and 29% met the criteria for chronic fatigue, with positive assessments at four or more time points over the course of a year. In addition, 40%, 30%, and 18% of participants reported taking medication in the past 7 days for pain, mental health, and sleep, respectively.
The findings suggest that patients with CF might benefit from routine assessments of non-pulmonary symptoms in clinical care and from access to health care providers, including mental health professionals, to address non-pulmonary concerns, the researchers wrote in their abstract.
“We delayed starting the study until elexacaftor/tezacaftor/ivacaftor (ETI) was FDA-approved because there was an assumption that people with CF would have less fatigue because of respiratory improvements from ETI,” Dr. Riekert told this news organization. “Instead, the prevalence of fatigue and poor sleep quality was higher and more chronic than we had anticipated,” she noted.
However, “we were pleasantly surprised that depression and anxiety, while still prevalent, were less prevalent and chronic than previously reported,” Dr. Riekert said in an interview. “We attribute this to the CF Foundation’s mental health initiative that has increased the frequency of annual screening for depression and anxiety and provided resources to help people with cystic fibrosis obtain mental health services,” she said.
The study findings suggest that clinicians should assess people with CF for chronic fatigue and poor sleep along with depression and anxiety and provide treatment or referral, Dr. Riekert said. “For example, cognitive behavioral therapy can effectively treat all the symptoms that were measured in our study,” she noted.
Limitations of the study include the lack of data on how the non-respiratory symptoms interact with respiratory symptoms or pulmonary exacerbations, said Dr. Riekert. “While we assessed these symptoms five times, it was for a year; longer-term follow-up seems merited given our findings,” she said. In addition, “we need to study approaches to make cognitive behavioral therapy and other therapy more accessible for people with cystic fibrosis,” Dr. Riekert said.
Targeting Non-Pulmonary Dimensions of CF Care
The current study highlights an aspect of quality of life that is often forgotten when managing adults with CF and may affect their well-being despite effective therapy to improve function and prolong life, said Wissam Chatila, MD, professor of thoracic medicine and surgery at the Lewis Katz School of Medicine at Temple University, Philadelphia, in an interview.
The high incidence of poor sleep, fatigue, depression, and anxiety seen in the current study was “somewhat surprising,” Dr. Chatila said. Also somewhat surprising was the chronicity of the symptoms considering the cystic fibrosis transmembrane conductance regulator (CFTR) modulator therapies (designed to correct the malfunctioning protein made by the CFTR gene) that have changed the face of CF, he noted.
However, recent growth in the number of adult patients with CF (more than 50% in certain countries) has led to a change in pathologies that physicians have to manage, and the current study addresses some of the emerging pathologies, said Dr. Chatila.
“Beyond demonstrating survival data from registries and other epidemiologic studies, this study sheds light on the need to address patient-reported outcomes that may or may not be directly related to the pulmonary and GI effects of the CFTR modulators,” he said. “Recognizing the extent of the dysfunction that many CF patients continue to suffer from will eventually lead to identifying factors that contribute to poor outcomes and the mechanisms involved,” he added.
Overall, the current study illustrates the potential benefits of offering personalized medicine to adults with CF that improves not only their physical function but also their mental health, Dr. Chatila said.
The study was funded by the Cystic Fibrosis Foundation. Dr. Riekert had no financial conflicts to disclose. Dr. Chatila had no financial conflicts to disclose.

Young People’s Gut Bacteria May Drive Colorectal Cancer Risk
CHICAGO — Genetics and diet have been among the top theories for what may be fueling the troubling rise of colorectal cancer in young adults. Now,
The findings were presented at the annual meeting of the American Society for Clinical Oncology (ASCO) by researchers from Ohio State University. For the analysis, they analyzed genetic data on tumors.
The researchers found signs that a high-fat, low-fiber diet may increase inflammation in the gut that prevents it from naturally suppressing tumors. The cells of young people with colorectal cancer also appeared to have aged more quickly — by 15 years on average — than a person’s actual age. That’s unusual, because older people with colorectal cancer don’t have the same boost in cellular aging.
The rate of colorectal cancer among young people has been rising at an alarming rate, according to a 2023 report from the American Cancer Society. In 2019, one in five colorectal cancer cases were among people younger than 55. That’s up from 1 in 10 in 1995, which means the rate has doubled in less than 30 years.

A 2017 analysis estimated that a person’s risk of colorectal cancer increased 12% by eating 3.5 ounces of red or processed meat daily, which is the equivalent of the size of a deck of playing cards. The same study also linked colorectal cancer risk to alcohol intake, citing its ethanol content. Eating a diet high in fiber can reduce a person’s risk.
This latest study aligned with previous findings that link bacteria called Fusobacterium to colorectal cancer. It’s not unusual for Fusobacterium to be present in a person’s mouth, but it is more likely to be found in the intestines of colorectal cancer patients, compared with those of healthy people. One study even found that people with colorectal cancer were five times more likely to have Fusobacterium in their stool, compared with healthy people.
Colorectal cancer is more common among men than women, “likely reflecting differences in risk factor prevalence, such as excess body weight and processed meat consumption,” the authors of the 2023 American Cancer Society report explained.
People younger than 45 should alert their medical provider if they have constipation, rectal bleeding, or sudden changes in bowel movements, which can be symptoms of colorectal cancer. Screening for colorectal cancer should begin for most people at age 45.

FROM ASCO 2024
Antidepressant Withdrawal Symptoms Much Lower Than Previously Thought
The incidence of antidepressant discontinuation symptoms appears to be much lower than was previously thought, results from a new meta-analysis of studies assessing this issue showed.
After accounting for placebo effects, results showed that about 15% of patients who discontinue antidepressant therapy had true discontinuation symptoms, with severe symptoms occurring in about 2% of patients.
“Considering all available data, we conservatively estimate that one out of every six to seven patients has truly pharmacologically-caused antidepressant discontinuation symptoms. This might still be an over-estimate, as it is difficult to factor in residual or re-emerging symptoms of depression or anxiety,” the researchers concluded.
The study was published online in The Lancet.
More Reliable Data
“We are not saying all antidepressant discontinuation symptoms are a placebo effect. It is a real phenomenon. And we are not saying that there is no problem discontinuing antidepressants. But these findings suggest that true antidepressant discontinuation symptoms are lower than previous studies have suggested,” study investigator, Christopher Baethge, MD, University of Cologne, Germany, said at a Science Media Centre press briefing.
“Our data should de-emotionalize the debate on this issue. Yes, antidepressant discontinuation symptoms are a problem, but they should not cause undue alarm to patients or doctors,” Dr. Baethge added.
Lead investigator, Jonathan Henssler, MD, Charité – Universitätsmedizin Berlin, Germany, noted that “previous studies on this issue have included surveys which have selection bias in that people with symptoms antidepressant discontinuation are more likely to participate. This study includes a broader range of research and excluded surveys, so we believe these are more reliable results.”
A Controversial Issue
The investigators note that antidepressant discontinuation symptoms can be highly variable and nonspecific, with the most frequently reported symptoms being dizziness, headache, nausea, insomnia, and irritability. These symptoms typically occur within a few days and are usually transient but can last up to several weeks or months.
Explaining the mechanism behind the phenomenon, Dr. Baethge noted that selective serotonin reuptake inhibitor antidepressants increase the available serotonin in the brain, but the body responds by reducing the number of serotonin receptors. If the amount of available serotonin is reduced after stopping the medication, then this can lead to discontinuation symptoms.
However, the incidence and severity of these symptoms remains controversial, the researchers noted. They point out that some estimates suggest that antidepressant discontinuation symptoms occurred in the majority of patients (56%), with almost half of cases classed as severe.
Previous attempts at assessment have been questioned on methodologic grounds especially because of inclusion of online surveys or other studies prone to selection and dissatisfaction bias.
“Medical professionals continue to hold polarized positions on the incidence and severity of antidepressant discontinuation symptoms, and the debate continues in public media,” they wrote.
This is the first publication of a larger project on antidepressant discontinuation symptoms.
For the study, the researchers conducted a meta-analysis of 44 controlled trials and 35 observational studies assessing the incidence of antidepressant discontinuation symptoms including a total of 21,002 patients. Of these, 16,532 patients discontinued antidepressant treatment, and 4470 patients discontinued placebo.
Incidence of at least one antidepressant discontinuation symptom occurred in 31% of patients stopping antidepressant therapy and in 17% after discontinuation of placebo, giving a true rate of pharmacologic-driven antidepressant discontinuation symptoms of 14%-15%.
The study also showed that severe discontinuation symptoms occurred in 2.8% of those stopping antidepressants and in 0.6% of those stopping placebo, giving a true rate of severe antidepressant discontinuation symptoms of around 2%.
There was no association with treatment duration or with pharmaceutical company funding, and different statistical analyses produced similar results, suggesting the findings are robust, Dr. Baethge reported.
Risks by Medication
Desvenlafaxine, venlafaxine, imipramine, and escitalopram were associated with higher frequency of discontinuation symptoms and imipramine, paroxetine, and either desvenlafaxine or venlafaxine were associated with a higher severity of symptoms.
Fluoxetine, sertraline, and citalopram had lower rates of discontinuation symptoms. No data were available for bupropion, mirtazapine, and amitriptyline.
As for the clinical implications of the findings, Dr. Henssler said that he does consider discontinuation symptoms when selecting a medication. “I would choose a drug with lower rate of these symptoms unless there was a specific reason to choose one with a higher rate,” he said.
Dr. Henssler added that these data raise awareness of the placebo effect.
“Considering the placebo results, approximately half of antidepressant discontinuation symptoms could be attributable to expectation or non-specific symptoms,” the researchers noted.
“This is not to say all antidepressant discontinuation symptoms are caused by patient expectations; in practice, all patients discontinuing antidepressants need to be counseled and monitored, and patients who report antidepressant discontinuation symptoms must be helped, in particular those who develop severe antidepressant discontinuation symptoms,” they concluded.
Experts Weigh In
Commenting on the study at a press briefing, Oliver Howes, MD, chair of the psychopharmacology committee at the Royal College of Psychiatrists, United Kingdom, said that he welcomed “the insight that this robust study provides.”
“If someone chooses to stop taking their antidepressants, their doctor should help them to do so slowly and in a controlled manner that limits the impact of any potential withdrawal symptoms,” Dr. Howes said.
He added that the Royal College of Psychiatrists has produced a resource for patients and carers on stopping antidepressants that offers information on tapering medication at a pace that suits individual patient needs.
Also commenting, Tony Kendrick, MD, professor of primary care, University of Southampton, United Kingdom, pointed out some limitations of the new meta-analysis — in particular, that the method of assessment of discontinuation symptoms in the included studies was very variable, with specific measurement scales of discontinuation symptoms used in only six of the studies.
“In most cases the assessment seemed to depend at least partly on the judgment of the authors of the included studies rather than being based on a systematic collection of data,” Dr. Kendrick added.
In an accompanying editorial, Glyn Lewis, PhD, and Gemma Lewis, PhD, University College London, United Kingdom, wrote that though the meta-analysis has its limitations, including the fact that many of the studies were small, often use antidepressants that are not commonly used now, and studied people who had not taken the antidepressants for a very long time, “the results here are a substantial improvement on anything that has been published before.”
They emphasize the importance of discussing the issue of a placebo effect with patients when stopping antidepressants.
The editorialists pointed out that as antidepressants are prescribed to many millions of people, the relatively uncommon severe withdrawal symptoms will still affect a substantial number of people. However, for individual clinicians, severe withdrawal symptoms will seem uncommon, and most patients will probably not be troubled by antidepressant withdrawal, especially when medication is tapered over a few weeks.
They noted that cessation of antidepressants can lead to an increase in depressive and anxious symptoms, and distinguishing between relapsing symptoms and withdrawal is difficult.
“Short-term symptoms that reduce quickly, without intervention, are best thought of as a form of withdrawal, even if those symptoms might be similar or identical to the symptoms of depression and anxiety. More serious and longer-term symptoms might best be managed by tapering more slowly, or even deciding to remain on the antidepressant,” the editorialists wrote.
There was no funding source for this study. The authors declare no competing interests. Dr. Kendrick led the NIHR REDUCE trial of internet and telephone support for antidepressant discontinuation and was a member of the guideline committee for the NICE 2022 Depression Guideline.

FROM THE LANCET
Red Flags for Early-Onset Colorectal Cancer Identified
TOPLINE:
Patients with early-onset colorectal cancer (EOCRC) often present with hematochezia or abdominal pain, symptoms frequently overlooked in younger populations, leading to delays in diagnosis of 4-6 months, a new analysis showed.
METHODOLOGY:
- As the number of cases of EOCRC, defined as colorectal cancer (CRC) diagnosed before age 50, continues to rise, early detection has become increasingly important. Improved recognition of presenting signs and symptoms associated with EOCRC could lead to a more timely diagnosis and better clinical outcomes.
- In a systematic review and meta-analysis of 81 studies with 24.9 million EOCRC cases, researchers sought to determine the most common presenting signs and symptoms, their association with EOCRC risk, and the time from presentation to diagnosis.
- Data extraction and quality assessment were performed independently in duplicate using PRISMA guidelines, and Joanna Briggs Institute critical appraisal tools were used to measure the risk of bias.
TAKEAWAY:
- Hematochezia was the most common presenting sign/symptom, with a pooled prevalence of 45%, followed by abdominal pain, with a pooled prevalence of 40%.
- Altered bowel habits, which included constipation, diarrhea, and alternating bowel habits, were the third most common presenting sign/symptom (pooled prevalence of 27%), followed by unexplained weight loss (pooled prevalence of 17%).
- The likelihood of EOCRC was estimated to be fivefold to 54-fold higher with hematochezia and 1.3-fold to sixfold higher with abdominal pain.
- The mean time from sign or symptom onset to EOCRC diagnosis was 6.4 months (range, 1.8-13.7 months).
IN PRACTICE:
“These findings and the increasing risk of CRC in individuals younger than 50 years highlight the urgent need to educate clinicians and patients about these signs and symptoms to ensure that diagnostic workup and resolution are not delayed. Adapting current clinical practice to identify and address these signs and symptoms through careful clinical triage and follow-up could help limit morbidity and mortality associated with EOCRC,” the authors wrote.
SOURCE:
The study, with Joshua Demb, PhD, MPH, division of gastroenterology, department of medicine, University of California, San Diego, was published online May 24 in JAMA Network Open.
LIMITATIONS:
Significant heterogeneity across studies affected the ability to meta-analyze some results. The cross-sectional data limited the ability to stratify by age, sex, race and ethnicity, or genetic ancestry. It was not possible to evaluate the impact of time to diagnosis on CRC outcomes due to a limited number of studies answering this question. Researchers were unable to examine the constellation of signs and symptoms because they lacked individual-level data from each study.
DISCLOSURES:
The authors disclosed no relevant conflicts of interest. No specific funding was disclosed.

TOPLINE:
Patients with early-onset colorectal cancer (EOCRC) often present with hematochezia or abdominal pain, symptoms frequently overlooked in younger populations, leading to delays in diagnosis of 4-6 months, a new analysis showed.
METHODOLOGY:
- As the number of cases of EOCRC, defined as colorectal cancer (CRC) diagnosed before age 50, continues to rise, early detection has become increasingly important. Improved recognition of presenting signs and symptoms associated with EOCRC could lead to a more timely diagnosis and better clinical outcomes.
- In a systematic review and meta-analysis of 81 studies with 24.9 million EOCRC cases, researchers sought to determine the most common presenting signs and symptoms, their association with EOCRC risk, and the time from presentation to diagnosis.
- Data extraction and quality assessment were performed independently in duplicate using PRISMA guidelines, and Joanna Briggs Institute critical appraisal tools were used to measure the risk of bias.
TAKEAWAY:
- Hematochezia was the most common presenting sign/symptom, with a pooled prevalence of 45%, followed by abdominal pain, with a pooled prevalence of 40%.
- Altered bowel habits, which included constipation, diarrhea, and alternating bowel habits, were the third most common presenting sign/symptom (pooled prevalence of 27%), followed by unexplained weight loss (pooled prevalence of 17%).
- The likelihood of EOCRC was estimated to be fivefold to 54-fold higher with hematochezia and 1.3-fold to sixfold higher with abdominal pain.
- The mean time from sign or symptom onset to EOCRC diagnosis was 6.4 months (range, 1.8-13.7 months).
IN PRACTICE:
“These findings and the increasing risk of CRC in individuals younger than 50 years highlight the urgent need to educate clinicians and patients about these signs and symptoms to ensure that diagnostic workup and resolution are not delayed. Adapting current clinical practice to identify and address these signs and symptoms through careful clinical triage and follow-up could help limit morbidity and mortality associated with EOCRC,” the authors wrote.

Significant heterogeneity across studies affected the ability to meta-analyze some results. The cross-sectional data limited the ability to stratify by age, sex, race and ethnicity, or genetic ancestry. It was not possible to evaluate the impact of time to diagnosis on CRC outcomes due to a limited number of studies answering this question.

‘Practice Changing’ Results for Osimertinib in Unresectable Stage III EGFR+ NSCLC
CHICAGO — Osimertinib (Tagrisso) may soon have approvals across all stages of epidermal growth factor receptor (EGFR)–mutated non–small cell lung cancer (NSCLC).
The third-generation EGFR tyrosine kinase inhibitor (TKI) already carries indications for metastatic disease and for adjuvant use in earlier-stage EGFR-mutated NSCLC.
Results from the phase 3 LAURA trial, presented at the American Society of Clinical Oncology (ASCO) annual meeting and funded by AstraZeneca, will likely lead to an approval for the remaining indication: Unresectable stage III disease.
The news was greeted with a standing ovation at the meeting where it was presented by lead investigator and medical oncologist Suresh S. Ramalingam, MD, a lung cancer specialist at Emory University, Atlanta.
David R. Spigel, MD, a discussant on the trial, called the results “outstanding.”
“To have an 84% reduction in the risk of cancer progression or death is meaningful,” said Dr. Spigel, a medical oncologist at the Sarah Cannon Research Institute, Nashville, Tennessee, who reported ties to AstraZeneca. “This will be practice changing as soon as the label gets expanded.”
In the trial, investigators randomized 216 patients with unresectable stage III EGFR-mutated NSCLC who had not progressed after definitive platinum-based chemoradiation to receive either 80 mg osimertinib (n = 143) or placebo (n = 73). Baseline characteristics were generally balanced between the study arms, with a mostly even split between stage III subtypes.
Patients were staged by biopsy or CT at baseline plus MRI to confirm the absence of brain lesions. Subsequent imaging was repeated at regular intervals.
Twelve-month progression-free survival, assessed by blinded independent central review, was 74% with osimertinib vs 22% with placebo. At 24 months, the rates were 65% and 13%, respectively.
The progression-free survival benefit held across numerous subgroups but was statistically significant only among Asian individuals, who made up over 80% of both study arms.
Although the data are immature, osimertinib is also showing a trend toward improved overall survival, despite 81% of placebo patients crossing over to osimertinib after progression, Dr. Ramalingam reported. Mature overall survival results are expected within 2 years.
Based on these results, “osimertinib will become the new standard of care” after definitive chemoradiation in this patient population, Dr. Ramalingam said.
EGFR mutation testing “is now critical for stage III patients to ensure optimal” treatment, he added. Nearly a third of patients with NSCLC present with stage III disease, and the majority are unresectable. Of those, about a third are EGFR mutated.
Placebo was a fair comparator in the trial, Dr. Ramalingam stressed. While the current standard of care for unresectable stage III disease is 1 year of durvalumab after chemoradiation, durvalumab has proven ineffective in EGFR-mutated disease and often isn›t used in the setting.
If the control arm had been on durvalumab, patients would have needed to wait until it was safe to give them an EGFR TKI after progression, which didn’t seem to be in their best interest, he told this news organization.
A total of 68% of patients receiving placebo developed new lesions during the study, including brain metastases in 29%. New lesions developed in 22% of those on osimertinib, with new brain lesions in 8%.
The incidence of radiation pneumonitis, the most common adverse event, was 48% with osimertinib and 38% with placebo. Skin rash, diarrhea, and other known TKI side effects were also more common with osimertinib.
Treatment-related grade 3 or worse adverse events occurred in 13% of osimertinib patients vs 3% of placebo patients. Overall, 8% of osimertinib patients developed interstitial lung disease; most cases were low grade, but one person died.
About half of patients interrupted osimertinib dosing due to side effects, with a minority discontinuing.
Another study discussant, medical oncologist Lecia Sequist, MD, called the results “practice-changing” and said the findings support immediate consolidation with osimertinib instead of waiting for patients to progress.
Dr. Sequist, who reported ties to AstraZeneca, noted that patients were treated with osimertinib until progression, not for a limited duration as in past EGFR TKI trials, raising the possibility of indefinite, life-long treatment.
Treating until progression acknowledges the fact that for most patients, unresectable stage III NSCLC can’t be cured. However, she said a minority of patients might not need indefinite treatment — an important cohort to identify, given the drug costs more than $18,000 a month.
The study was funded by osimertinib maker AstraZeneca. Investigators included employees. Dr. Ramalingam, Dr. Spigel, and Dr. Sequist are advisers for and disclosed research funding from AstraZeneca. Dr. Spigel also disclosed travel funding.

FROM ASCO 2024
Patients With Hypersensitivity Pneumonitis Want More Disease Information
Adults with hypersensitivity pneumonitis (HP) expressed interest in more knowledge of prognosis, etiology, treatment, and living well with the disease, based on new survey data presented at the American Thoracic Society International Conference.
HP is caused by environmental exposure and is often incurable, and patients are challenged with identifying and mitigating the exposure with limited guidance, wrote Janani Varadarajan, MD, of Weill Cornell Medicine, New York, and colleagues.
Surveys Conducted to Understand Patient Concerns
To better identify patient-perceived HP knowledge gaps and develop educational resources, the researchers assessed 21 adults diagnosed with HP. Patients underwent interviews using nominal group technique (NGT) for group consensus and completed a survey on educational preferences. The mean age of the participants was 69.5 years, and 81% were women.
The researchers conducted five NGTs. Participants were asked two questions: What questions about your HP do you have that keep you awake at night?” and “What information do you want about your HP that you cannot find?” They also voted on responses that were grouped by theme.
The top themes that emerged from the interviews were concerns about natural history and prognosis of HP (28.3%), current treatment options and therapeutic research (22.5%), epidemiology and etiology (17.5%), living well with HP (15.4%), origin and management of symptoms (8.3%), identifying and mitigating exposures (4.6%), and methods of information uptake and dissemination (3.3%).
The findings were limited by the relatively small sample size. However, the results will inform the development of educational materials on the virtual Patient Activated Learning System, the researchers noted in their abstract. “This curriculum will be a component of a larger support intervention that aims to improve patient knowledge, self-efficacy, and HRQOL [health-related quality of life],” they said.
Findings Will Fuel Needed Education
Recognizing more interstitial lung disease (ILD) has led to diagnosing more hypersensitivity pneumonitis, and it is important to keep patients’ concerns in mind, said Aamir Ajmeri, MD, assistant professor of clinical thoracic medicine and surgery at the Lewis Katz School of Medicine at Temple University, Philadelphia, in an interview.
“If patients research ILD online, most of the literature is based on idiopathic pulmonary fibrosis,” he said. “IPF literature can be frightening because patients will see a median 2- to 5-year survival rate from time of diagnosis, the need for lung transplant, and progressive hypoxemia; however, all of this may not be true in HP,” he noted.
“HP is more of a spectrum, but it is more difficult for patient to understand when we say ‘your lungs have reacted to something in your environment,’ and they will ask ‘what can I do to change this?’” Dr. Ajmeri told this news organization. “That is why these types of studies, where we recognize what patients need and how they can learn more about their diagnosis, are very important,” he said.
The study findings were not surprising, Dr. Ajmeri said. “We have a large cohort of patients with HP at Temple Health, and these are the same questions they ask me and my colleagues,” he said. “It can be tough for patients to grasp this diagnosis. We know it is related to something inhaled from the environment, but it may be difficult to pinpoint,” he said.
In patient-centered research, patients can help shed light onto the needs that are unmet for the disease process by asking hypothesis-generating questions, Dr. Ajmeri said. For example, he said he is frequently asked by patients why HP continues to recur after they have remediated a home (potential source of exposure) and been on medication.
“The study was limited in part by the small sample size but captured a good representation of what patients are asking their physicians about,” Dr. Ajmeri said. Although it is always preferable to have more patients, the findings are important, “and the educational materials that they will lead to are greatly needed,” he said.
The study was supported by the Stony Wold-Herbert Fund, the American Lung Association Catalyst Award, and the National Heart, Lung, and Blood Institute. The researchers had no financial conflicts to disclose. Dr. Ajmeri had no financial conflicts to disclose.
