Treatment of chronic back pain remains a challenge for primary care physicians, and a new Cochrane Review confirms previous studies suggesting that analgesics and antidepressants fall short in terms of relief.

Data from another Cochrane Review support the value of exercise for chronic low back pain, although it is often underused, and the Food and Drug Administration’s recent approval of a spinal cord stimulation device for chronic back pain opens the door for another alternative.

Regardless of treatment type, however, patients report that empathy and clear communication from their doctors go a long way in their satisfaction with pain management, according to another recent study.
 

Exercise helps when patients adhere

The objective of the Cochrane Review on “Exercise therapy for chronic low back pain” was to determine whether exercise improves pain and functioning for people with chronic low back pain, compared with no treatment, usual care, or other common treatments, corresponding author Jill Hayden, PhD, of Dalhousie University, Halifax, N.S., said in an interview.

When back pain is chronic, it is expensive in terms of health care costs and lost work hours, said Dr. Hayden. “Exercise is promoted in many guidelines and is often recommended for, and used by, people with chronic low back pain.” However, “systematic reviews have found only small treatment effects, with considerable variation across individual trials.”

The 2021 review is one of the largest in the Cochrane Library, and included 249 trials and 24,486 study participants. However, Dr. Hayden said she had been disappointed by the methodological limitations of many of the trials. “The field is saturated with small exercise trials, many of which suffer from poor planning, conduct, and reporting due to limited resources.”

In the current review, “we found that exercise is likely to be effective for chronic low back pain. Overall, 3 months after the start of treatment, people receiving exercise treatment rated their pain an average of 15 points better on a scale of 0-100, and functional limitations were 7 points better, compared to people who had no treatment or usual care,” said Dr. Hayden.

Barriers to the use of exercise to treat pain may include fear of movement on the part of patients, she noted.

“Although our related network meta-analysis found some differences between specific types of exercise, we found all exercise types are more effective than minimal treatment,” she said. “People with chronic low back pain should be encouraged to do exercises that they enjoy and will do consistently to promote adherence.”
 

Limitations of medications

Both the safety and effectiveness of analgesics and antidepressants for pain in general and back pain in particular have come under scrutiny in recent research. A study published online in the British Medical Journal of patients with acute low back pain found that, although some medications were associated with large reductions in pain intensity, compared with placebo, the quality of the studies was “low or very low confidence,” according to a Medscape report on the findings.

This conclusion was supported in a large-scale analysis of the safety and effectiveness of antidepressants in chronic pain conditions, including back pain.

A new Cochrane Review led by a team of researchers in the United Kingdom found inadequate evidence to support the effectiveness of most antidepressants used for chronic pain, including amitriptyline, fluoxetine, citalopram, paroxetine, sertraline, and duloxetine.

“While chronic pain remains one of the top causes of daily disability worldwide, clinicians’ choices at offering interventions are getting fewer, especially if they tend toward a medical model and want a pharmacological solution,” corresponding author Tamar Pincus, PhD, of the University of Southampton (England), said in an interview. “We now know that opioids harm patients, and the evidence for common analgesics such as paracetamol and ibuprofen, for some conditions such as back pain, suggest they are not effective and might cause harm. This leaves clinicians with few options, and the most common prescription, supported by guidelines, is antidepressants.”

The study found moderate evidence that duloxetine can reduce pain in the short term and improve physical activity and some evidence that milnacipran might also be effective, Dr. Pincus said. “For all other antidepressants, including the commonly prescribed amitriptyline, the evidence was poor. Of importance, the average length of trials was 10 weeks, so long-term effects for all antidepressants remain unknown, and side effects and adverse events were reported poorly, so we also don’t know if any antidepressants are harmful.”

The takeaway message for the management of back pain in particular? “If a clinician and a patient decide together that it would be a good idea to try an antidepressant to reduce pain, they should consider starting with duloxetine, the drug with supporting evidence,” she said.
 

Physician attitude matters

Antidepressants may not have much impact on chronic pain, but a physician’s empathy and support do, according to data from a registry study of more than 1,300 individuals.

Despite efforts and guidelines from multiple medical organizations to promote optimal pain management, “much remains unknown regarding how the patient-physician interaction affects the process of delivering medical care for chronic low back pain and, ultimately, patient satisfaction,” John C. Licciardone, DO, of the University of North Texas Health Science Center, Fort Worth, and colleagues wrote in Annals of Family Medicine.

Previous studies have examined the relationship between clinical outcomes and patient satisfaction, but data on patient satisfaction with medical care for chronic low back pain specifically are limited, they said.

The researchers reviewed data from a national pain registry of adults aged 21-79 years that included self-reported measures of physician communication and empathy, prescribing data for opioids, and outcomes data for pain intensity, physical function, and health-related quality of life.

In a multivariate analysis, physician empathy and physician communication showed the strongest associations with patient satisfaction (P < .001).

The researchers found a negligible correlation between opioid prescription and perceived physician empathy and communication, “although current physician prescribing of opioids was also associated with patient satisfaction,” they wrote.

“Our findings pertaining to physician empathy are intriguing because they do not necessarily involve a therapeutic alliance with the patient based on collaborative communication or the expectation of a therapeutic effect via pharmacotherapy,” the researchers wrote .

The findings were limited by several factors including the cross-sectional design that prevented conclusions about cause and effect, the researchers noted. “It is possible that prior improvements in pain intensity, physical function, or [health-related quality of life] might have prompted participants to report more favorable ratings for physician empathy, physician communication, or patient satisfaction at registry enrollment.” However, the study supports the view that patients with low back pain in particular value physicians who validate their concerns and symptoms, and who make an effort to communicate treatment plans clearly.
 

Back pain patients continue to challenge primary care

“Back pain is a major issue in U.S. health care, in part because too many people have tough physical jobs or longstanding injuries that become chronic,” William Golden, MD, professor of medicine and public health at the University of Arkansas for Medical Sciences, Little Rock, said in an interview.

“There are no magic bullets for a lot of back pain patients, so empathy and support are key drivers,” he noted. “Helping patients maximize functionality as opposed to seeking mythical cures is the stronger line of visit discussions, but that takes a bit of time and skill in interviewing.

“It is fairly well established that duloxetine is useful in pain management, especially when present with mood disorders, either primary or secondary to the back-related disability,” said Dr. Golden. “Greater dissemination of its utility is probably useful, as is the side effect profile of the drug as well,” given the “nasty discontinuation syndrome when the treatment is reduced or stopped.”

Looking ahead, “more research is needed about microsurgery, namely for whom and for what anatomic presentations,” said Dr. Golden. Other topics for further research include a better understanding about medical marijuana and pain management and its interactions and side effects with other opioids and muscle relaxants. “Polypharmacy is still an issue in this class of patient,” and many of these patients are frustrated and angry “so the psychosocial skills of the PCP can be greatly tested as well,” he said.
 

Empathy promotes patient adherence to treatment

The new opioid prescription guidelines have increased interest among clinicians in how to improve patient satisfaction with the care for back pain provided, Noel Deep, MD, said in an interview. “These studies address this concern and bring forth an important aspect of the physician-patient relationship, namely the human touch and empathy.”

“I have been a strong proponent of the trust and relationship between a physician and patient; displaying empathy and increased and transparent communication between the physician and the patient has always resulted in better relationships and better outcomes for patients, especially those dealing with chronic health concerns,” said Dr. Deep, who is a general internist in a multispecialty group practice with Aspirus Antigo (Wisc.) Clinic and the chief medical officer and a staff physician at Aspirus Langlade Hospital, also in Antigo.

Potential barriers to effective pain management include beliefs and attitudes on the part of patients, Dr. Deep noted. “Physicians lacking adequate time to communicate effectively with the patient and describe nonopioid and nonsurgical interventions would be another potential barrier.” Other issues include the time and effort, as well as cost, associated with interventions such as physical therapy and other nondrug and nonsurgical interventions. Issues with family and social support and health literacy are also potential barriers to pain management.
 

Clinical takeaways

Low back pain is one of the most common reasons for a visit in primary care and can be “chronic and debilitating,” Grace Lin, MD, an internal medicine physician and primary care provider at the University of California, San Francisco, said in an interview.

“One issue with the Cochrane Review on exercise is that the studies on exercise were heterogeneous, so it’s difficult to know whether there is a particular kind of exercise that would be most effective and should be recommended to patients,” she said.

Furthermore, she said, “there is a physical therapist shortage in the U.S. I practice in a major city with a large health care system, and it can still take months to get an appointment with a physical therapist.” Also, insurance coverage may limit which therapists a patient can see and how many visits they can have.

“On the clinician side, I think physicians need to be better informed about the evidence base for back pain treatment, namely that exercise is effective and that, long term, analgesics are not,” Dr. Lin said. “This might decrease overprescription of ineffective analgesics and encourage more education about and referrals to physical therapy.”

“Physicians should continue to educate patients that physical therapy is the first-line treatment for back pain and that pain medications are secondary,” she said. “I think that analgesics can be effective for the short term to get people to a point where they feel well enough to do physical therapy. Duloxetine also appears to be moderately effective for chronic low back pain, in part because it may also help address coexisting depression and anxiety,” but these options should be reserved for adjuncts to physical therapy for back pain.

The findings from the study on empathy and communication suggest that the main challenges to these behaviors are systemic, said Dr. Lin.

“Our health care system is not conducive to treating chronic back pain,” she said. Primary care visits that last for 15 or 20 minutes are not long enough to diagnose and counsel patients on such a complex problem as chronic low back pain. Since back pain is usually not the only issue the primary care physician is dealing with during that visit, this can lead to patients feeling like their doctor isn’t listening to them and doesn’t care about their pain.

“We need to better understand the mechanisms by which people develop chronic, debilitating back pain,” Dr. Lin said. “I think if we understood this better, more effective and targeted treatments, both pharmacological and nonpharmacological, could be developed.”

The Annals of Family Medicine study received no outside funding, and the researchers had no financial conflicts to disclose. The Cochrane Reviews was supported by the National Institute for Health and Care Research’s Health Technology Assessment program, and the authors had no financial conflicts to disclose. Dr. Golden and Dr. Deep had no financial conflicts to disclose and serve on the editorial advisory board of Internal Medicine News. Dr. Lin disclosed receiving research funding from the Institute for Clinical and Economic Review and the National Institutes of Health.

CHICAGO – In celiac disease, one of the most promising areas of research includes the development of treatments that target HLA-DQ2 gene variants associated with the condition.

There are a number of clinical trials underway, including one for the investigational drug TPM502, which carries three gluten-specific antigenic peptides with overlapping T-cell epitopes for the HLA-DQ2.5 gene. And, research is underway for the novel KAN-101, which aims to restore the immune tolerance of gluten by targeting receptors on the liver.

During the annual Digestive Disease Week® (DDW), researchers shared the results from a new proof-of-concept study for DONQ52, a bispecific antibody that targets HLA-DQ2.5. DONQ52 was found to be highly effective in blocking gluten-specific T cells, said investigator Jason A. Tye-Din, PhD, a researcher with The Walter and Eliza Hall Institute of Medical Research, Melbourne, and an investigator with Chugai Pharmaceutical, which is funding the DONQ52 research which has since advanced to a phase 1 study of 56 patients.

There are no existing drug therapies for celiac disease, which leaves patients with a lifelong, and strict, gluten-free diet as treatment. This strategy, however, often fails to induce mucosal healing or symptom control, and has stimulated a search for novel therapies, said Melinda Y. Hardy, PhD, a postdoctoral researcher with the University of Melbourne, and the first author of the DONQ52 study. While targeting the gluten-specific immune response is highly attractive, it presents safety and pharmacokinetic challenges, so a better alternative would be to develop antibodies that selectively bind to HLA-DQ2.5, which is found in 80%-90% of celiac disease patients, she said. DONQ52 blocks at least 25 gluten peptides, and binds specifically to complexes of HLA-DQ2.5 and a range of immunogenic gluten peptides.

The study included 20 patients who consumed wheat bread for 3 days. Blood samples were taken 1 day before the start of the trial and 6 days after it concluded. Twenty patients were found to be wheat challenged, 10 were barley challenged, and 14 were rye challenged.

All were tested for gluten-specific T-cell responses in the presence or absence of DONQ52, which was designed to reduce the wheat-specific T-cell response because 90% of gluten intake is from wheat. “If you have celiac disease, you have a reservoir of these gluten-specific T cells. When you eat gluten, they’ll be activated and switched on and that’s what we want to block,” Dr. Tye-Din said.

The main assessment – a day 6 wheat challenge among 15 responders – revealed a more than 80% reduction in T-cell responses to a peptide cocktail. DONQ52 also reduced barley and rye T cell responses in a day 6 challenge, although to a lesser degree (40%/80%).

“DONQ52 is designed to target individual peptides that trigger the disease, and we showed that it did it very well to the wheat peptides, well over 80%. That’s a very impressive reduction in responses,” he said. A further test among 20 samples showed that DONQ52 did not activate T-cells nonspecifically. “You don’t want to trigger an unnecessary response,” Dr. Tye-Din added.

“DONQ52 effectively reduces activation of wheat gluten-specific T cells. It also has broad reactivity extending to barley and rye T-cell epitopes,” said Dr. Hardy.

The study was funded by Chugai Pharmaceutical. Dr. Hardy is a coinventor on a provisional patent describing oats peptides in celiac disease therapeutics and diagnostics. Dr. Tye-Din disclosed associations with Chugai, Genentech, Janssen, and Takeda, among others.

CHICAGO – In celiac disease, one of the most promising areas of research includes the development of treatments that target HLA-DQ2 gene variants associated with the condition.

There are a number of clinical trials underway, including one for the investigational drug TPM502, which carries three gluten-specific antigenic peptides with overlapping T-cell epitopes for the HLA-DQ2.5 gene. And, research is underway for the novel KAN-101, which aims to restore the immune tolerance of gluten by targeting receptors on the liver. It received Fast Track designation by the Food and Drug Administration in 2022.

Upadacitinib in the management of Crohn's disease and novel data challenging standard clinical practice are some of the inflammatory bowel disease (IBD) highlights from Digestive Disease Week (DDW) 2023, as reported by Dr Joseph Feuerstein, from Harvard Medical School, Boston, Massachusetts.

Dr Feuerstein begins by discussing two studies of upadacitinib induction and maintenance in Crohn's disease. Both studies showed that the drug achieved higher fistula closure and remission rates than did placebo, regardless of prior biologic therapy exposure.

The third study chosen by Dr Feuerstein asks whether early resection of ileocecal Crohn's disease might achieve better outcomes than would standard anti–tumor necrosis factor therapy. The study results suggested that early resection could postpone the need for medication for longer than previously thought.

More potentially practice-changing data comes from the SuPREMe-CD study, which showed that using Kono-S anastomosis reduced endoscopic recurrence of Crohn's disease compared with traditional side-to-side anastomosis.

Dr Feuerstein next discusses an analysis of the SAPPHIRE Registry, which found that IBD treatments were not linked to cancer risk. In closing, he reports on a study that showed longer withdrawal time during colonoscopy, meaning longer time spent examining the colon, is associated with improved detection of polypoid dysplasia.

CHICAGO – Irrespective of the number of infliximab switches, multiple, successive switches from infliximab originator to biosimilars are effective and safe in patients with inflammatory bowel disease (IBD), according to analysis of a real world IBD cohort presented at the annual Digestive Disease Week® (DDW).

“These findings are of major socioeconomic importance, especially in low- and middle-income countries where the access to health care may be limited,” said study author Beatriz Gros, MD, an advanced clinical fellow in gastroenterology at Western General Hospital of Edinburgh.

While switching from originator infliximab to biosimilar infliximab is known observationally to be safe and effective, data on single and double switches are scarce, and are lacking on triple switches. Infliximab, the first monoclonal antibody biologic inhibiting anti–tumor necrosis factor was approved by the Food and Drug Administration and by the European Medicines Agency in 1998 and 1999, respectively. Economic pressures led to the development of biosimilars, with the first EMA approval in 2013 and FDA approval in 2016. Uptake in Europe has been broad and expanding following evidence that early therapy is associated with better outcomes. In the United States, a recent RAND Corporation study estimated savings to be $38.4 billion or 5.9% of projected total spending on biologics from 2021 to 2025, Dr. Gros reported.

The Edinburgh IBD unit has undertaken three switch programs starting with originator to CT-P13 in 2016, CT-P13 to SB2 in 2020, and SB2 to CT-P13 in 2021. Their prospective, observational cohort study assessing safety and efficacy after switching from SB2 to CT-P13 has, as a primary endpoint, CT-P13 persistence following the switch from SB2. Stratification of persistence according to the number of switches, effectiveness, immunogenicity, and safety were secondary outcomes.

During routine virtual biologic clinic care, researchers collected clinical disease activity scores (Harvey-Bradshaw Index; partial Mayo score), laboratory parameters (including C-reactive protein [CRP], IFX trough, and antibody levels), and fecal calprotectin on 297 IBD patients (median age, 37 years; 61.6% male). Among them, 67 had three switches, 138 had two switches, and 92 had one switch. Median disease duration was longer (11.4 years) for those with three switches than for two switches (6.3 years) or one switch (2.3 years) (P < .0001)

Infliximab persistence

Out of 297 patients, 269 (90.6%) remained on infliximab at week 24. Reasons for discontinuing treatment were immunogenicity (15/297; 5.1%), secondary loss of response (7/297, 2.4%), adverse events (3/297, 1%), patient’s choice (2/297, 0.7%), and primary nonresponse (1/297, 0.3%).

While infliximab persistence was 82.6%, 92.8% and 97% in patients with one, two and three infliximab switches, respectively (P = .003), after confounder adjustment, the number of switches was not independently associated with infliximab persistence, Dr. Gros said.

What factors actually did predict infliximab persistence? Multivariable analysis identified absence of biochemical remission (CRP > 5 mg/L [hazard ratio, 3.21; 95% confidence interval, 1.43-7.24]); a diagnosis of ulcerative colitis/ inflammatory bowel disease unclassified (HR, 2.69; 95% CI, 1.19-6.06), detectable antibodies against infliximab at switch (HR, 5.81; 95% CI, 2.27-12.84) and time on infliximab (HR, 0.77; 95% CI, 0.62-0.95) as independent predictors for infliximab persistence rather than number of infliximab switches.

Clinical (P = .77), biochemical (P = .75), and fecal biomarker (P = .63) remission rates, Dr. Gros reported, were comparable at baseline, week 12 and week 24, with baseline rates for clinical, biochemical and fecal biomarker remission at 79.4%, 85.2%, and 85.3%, respectively, and at 81%, 86.5%, and 84.4% at week 24.

“Immunogenicity has been a major concern regarding multiple switches, although both our study and previous literature demonstrated that this seemed to be not happening more often to patients who had multiple switches compared to those who had fewer or none. Our study found that, of the 14 (7.1%) patients who developed de novo antibodies, none of them underwent three switches,” she said.

Dr. Gros disclosed relationships with Pfizer, AbbVie, and Jansen.

CHICAGO – Only 1%-3% of patients who have had bariatric surgery take Food and Drug Administration–approved antiobesity medications even though 25% of patients experience significant weight regain within a few years of surgery, according to a study presented at the annual Digestive Disease Week® meeting.

Obesity is a chronic, relapsing condition that must be treated as such, said the study’s author Stephen A. Firkins, MD, a fellow of gastroenterology and hepatology at the Cleveland Clinic. “Barriers to antiobesity medications must be identified.”

“If a quarter of all patients experience weight regain and another quarter experience insufficient weight loss – but only 5% are being prescribed an FDA-approved AOM – that means there’s underutilization,” Dr. Firkins said.

Data from the National Health and Nutrition Examination Survey show that 30.7% of all men and women in the United States are overweight and of these, 42.4% are obese. For the severely obese, bariatric surgery, including sleeve gastrectomy, Roux-en-Y gastric bypass, and one anastomosis gastric bypass, are viable options with differing degrees of long-term success.

And while antiobesity medications such as orlistat (Xenical, Alli), phentermine/topiramate (Qsymia), naltrexone/bupropion (Contrave), liraglutide (Saxenda), semaglutide (Wegovy), and setmelanotide (Imcivree), may be considered before bariatric surgery, there are questions about the need for its use after surgery.

“While these are often employed or considered presurgically, there is a paucity of literature describing their utilization postsurgically, particularly in regards to newer antiobesity medications such as the [glucagonlike peptide–1] receptor agonists,” Dr. Firkins said.

The aim of Dr. Firkins’ analysis of the large, publicly available IBM Explorys Electronic Health Record, which included 59,160 adult post–bariatric surgery patients, was to identify postoperative weight control medication use and trends among different populations.

He found rates of postsurgical weight control medication use at 8% for topiramate (off label), 2.9% for liraglutide, 1.03% for phentermine/topiramate, 0.95% for naltrexone/bupropion, 0.52% for semaglutide and 0.1% for orlistat. Rates of topiramate use were higher for patients in the 35- 39-year range, and for orlistat and liraglutide in the 65- to 69-year range.

The differences, Dr. Firkins said, were likely related to side-effect profiles and accumulations of comorbidities with advancing age. Black patients were more likely to be prescribed the medications. Also, further analysis showed a significantly higher use of these medications among individuals with hypertension, diabetes, and hyperlipidemia.

The analyses raised several questions for future study, Dr. Firkins said: “What is the optimal timing of antiobesity medication initiation? Is it at the plateau of peak weight loss typically seen at 1-3 years post surgery? Or, after weight is regained? What is the phenotype of patients who are going to be good responders versus poor responders to a particular medication category?”

“Upon recognition of insufficient weight loss/weight regain, a multidisciplinary strategy towards management is warranted, including behavioral and dietary counseling, and consideration of AOM early use, as well as endoscopic or surgical revision,” he said.

CHICAGO – Only 1%-3% of patients who have had bariatric surgery take Food and Drug Administration–approved antiobesity medications even though 25% of patients experience significant weight regain within a few years of surgery, according to a study presented at the annual Digestive Disease Week® meeting.

Obesity is a chronic, relapsing condition that must be treated as such, said the study’s author Stephen A. Firkins, MD, a fellow of gastroenterology and hepatology at the Cleveland Clinic. “Barriers to antiobesity medications must be identified.”

“If a quarter of all patients experience weight regain and another quarter experience insufficient weight loss – but only 5% are being prescribed an FDA-approved AOM – that means there’s underutilization,” Dr. Firkins said.

Data from the National Health and Nutrition Examination Survey show that 30.7% of all men and women in the United States are overweight and of these, 42.4% are obese. For the severely obese, bariatric surgery, including sleeve gastrectomy, Roux-en-Y gastric bypass, and one anastomosis gastric bypass, are viable options with differing degrees of long-term success.

And while antiobesity medications such as orlistat (Xenical, Alli), phentermine/topiramate (Qsymia), naltrexone/bupropion (Contrave), liraglutide (Saxenda), semaglutide (Wegovy), and setmelanotide (Imcivree), may be considered before bariatric surgery, there are questions about the need for its use after surgery.

“While these are often employed or considered presurgically, there is a paucity of literature describing their utilization postsurgically, particularly in regards to newer antiobesity medications such as the [glucagonlike peptide–1] receptor agonists,” Dr. Firkins said.

The aim of Dr. Firkins’ analysis of the large, publicly available IBM Explorys Electronic Health Record, which included 59,160 adult post–bariatric surgery patients, was to identify postoperative weight control medication use and trends among different populations.

He found rates of postsurgical weight control medication use at 8% for topiramate (off label), 2.9% for liraglutide, 1.03% for phentermine/topiramate, 0.95% for naltrexone/bupropion, 0.52% for semaglutide and 0.1% for orlistat. Rates of topiramate use were higher for patients in the 35- 39-year range, and for orlistat and liraglutide in the 65- to 69-year range.

The differences, Dr. Firkins said, were likely related to side-effect profiles and accumulations of comorbidities with advancing age. Black patients were more likely to be prescribed the medications. Also, further analysis showed a significantly higher use of these medications among individuals with hypertension, diabetes, and hyperlipidemia.

SAN FRANCISCO – Physically violent events at an inpatient psychiatric unit in Pennsylvania dropped by 59.8% in the months after it implemented a plan to administer antipsychotic medications to patients more quickly – both in the emergency department and in the unit – and improve handoffs between providers and nurses, researchers reported.

“We were able to significantly reduce violence,” said Michael Chen, MD, Lehigh Valley Health Network psychiatry resident and lead author of an abstract presented at the annual meeting of the American Psychiatric Association. “Furthermore, the interventions were effective in reducing episodes of violence rather than redirecting it. And the overall feeling of safety on the inpatient psychiatric unit improved.”

Violence is common in psychiatric units, although it’s not clear how often it occurs. “The data has shown that patients with a psychotic disorder such as schizophrenia or a mood disorder with psychotic features such as bipolar disorder tend to account for most of the episodes of violence on the unit,” Dr. Chen said in an interview. “This inevitably results in a higher risk for violence on inpatient psychiatric units as a large portion of patients admitted to inpatient psychiatric units have these diagnoses.”
 

Enlisting the pharmacy department

For the new study, investigators tracked episodes of violence – including verbal attacks – at an Allentown, Penn.–area inpatient psychiatric unit from December 2021 to September 2022. According to Dr. Chen, unit leaders implemented the new plan in May 2022 in the wake of higher levels of violence during the COVID-19 pandemic and the concurrent staff shortages.

Clinic leaders sought to identify potentially aggressive patients in the emergency department and treat them with antipsychotics prior to admission to the psychiatric unit, ensure that the pharmacy provides access to as-needed or standing medications, and develop “standardized huddles to ensure proper handoffs between providers and nurses.”

Medical staff relied on the Dynamic Appraisal of Situational Aggression scale, risk factors, and clinical judgment to determine which patients had the potential to be violent, Dr. Chen said.

As for treatment, first-line antipsychotics are typically given orally, but they can be injected if patients must be treated over their objections, he said. “We would only consider starting standing medications against objections in patients who are involuntarily committed.”

During the 5 months before the intervention was implemented versus the following 5 months, the average monthly number of physically violent events in the psychiatric unit fell from 12.4 to 4.8 (–61.1%, P = .04), and verbal threats dipped from 7.2 to 4 (–44.4%, P = .15). The total average number of violent events per month, including violence against property, fell from an average of 25.4 to 10.2 (–59.8%, P = .03).

The total patient population didn’t vary significantly over time, Dr. Chen said. “Thus, the decrease in violence was not correlated with a decrease in patient load.”

While “there were concerns that there would just be higher episodes of violence in the ED while psychiatry patients awaited placement,” Dr. Chen said, the numbers actually showed reductions in violence in that setting. The average number of physically violent events per month in the ED fell from 49.6 to 39.4 (–20.6%, P = .03). Verbal threats dropped from 38 to 34.6 (–8.9%, P = .5) and overall violent events dipped from 87.6 to 74 (–15.6%, P = .08).

Why did the interventions seem to work? “Standing doses as well as as-needed medications started for psychiatric patients in the emergency department have been crucial to prevent delay of care,” Dr. Chen said. Enlisting the pharmacy department “helped ensure all patients had appropriate as-needed medications to prevent them from decompensating on the units,” he added, and “involvement of nursing and ancillary staff in high-risk rounds allowed the treatment team to rapidly anticipate and address concerns.”

The study authors also reported that nursing staff felt safer. Scores on a perception-of-safety scale – with 1 most unsafe and 7 most safe – improved from 3.3 to 4.2 (+27%, P < .01).

Dr. Chen said there was a “minimal” increase in cost to implement the intervention, although coordination is necessary. “The emergency department and psychiatry department have to work together to initiate treatment in the ED while awaiting beds,” he said. “The treatment team needs to communicate concerns during rounds. The pharmacist and psychiatrist need to work together to ensure that proper as-needed medications are available.”
 

‘Good clinical practice’

In an interview, psychiatrist Mark J. Russ, MD, of NewYork-Presbyterian/Westchester Behavioral Health and Weill Cornell Medical College, said violent incidents in inpatient psychiatric units are influenced by many factors, such as history of violence, substance use, history of trauma, psychosis/paranoia, and medical problems.

The units themselves can contribute to the risk of violence through power struggles and lack of attention paid to respect and dignity, he said. “Attention to these issues is important in reducing violence,” he noted. “Generalized training for staff in de-escalation techniques and trauma-informed care is imperative. There may be value in developing specialized psychiatric ICUs where staff are meticulously trained in these and other approaches.”

The new study, Dr. Russ said, suggests that “early identification of patients at risk of engaging in violent behavior on the inpatient unit, pharmacologic treatment, and good communication helps reduce violence.” The findings, he added, suggest that “interventions known to constitute good clinical practice are indeed helpful.”

However, he cautioned that “treating all at-risk patients with antipsychotics, regardless of their psychiatric diagnosis, might well be considered chemical restraint, depending on [the] circumstances.”

There was no study funding. The study authors and Dr. Russ have no disclosures.

The Diagnosis: Actinic Prurigo

Actinic prurigo is an idiopathic photodermatosis triggered by UV exposure that primarily affects sun-exposed areas of the skin.^1,2 It typically presents as pruritic papules, plaques, and nodules, with most patients also experiencing oral tingling and pain.³ In more severe cases, it can progress to include conjunctival disease, scarring, and cheilitis.¹ A study of ocular findings among children with actinic pruritus reported that photophobia was one of the most important features,⁴ which was present in our patient. The face, especially over the zygomatic arches, nasal bridge, and lower lip, commonly is affected.1 Secondary lichenification or eczematization may occur.⁵ In our patient, the combination of conjunctivitis, cheilitis, and an eruption on sun-exposed skin were crucial in making the diagnosis.

Most cases present in patients younger than 10 years. It most commonly is seen in American Indians in North America, Central America, and South America.² After the diagnosis was considered in our patient, the family was asked about their ancestry and confirmed that both of the patient’s maternal and paternal grandparents were of American Indian descent. There also is a strong genetic component; the HLA-DR4 allele variant is present in 90% of cases, especially DRB1*0407, which is seen in 60% of cases.^1,6 In our patient, testing revealed HLA-DR4, DRB1*04 positivity. We further hypothesized that his mother’s photosensitive rash may have been actinic prurigo as opposed to polymorphous light eruption, which could explain the lack of response to hydroxychloroquine.

The diagnosis of actinic prurigo usually is made clinically. A skin biopsy typically is not necessary but would show hyperkeratosis, spongiosis, and acanthosis with a lymphocytic perivascular infiltrate. Biopsies of the lip classically show lymphoid germinal centers in the lamina propria, which can help distinguish actinic prurigo from polymorphous light eruption.¹

In our patient, the differential diagnosis included polymorphous light eruption, connective tissue disease such as lupus erythematosus or dermatomyositis, porphyria such as erythropoietic protoporphyria, and allergic contact dermatitis. Polymorphous light eruption was ruled out by the oral and ocular manifestations, which are not atypical for this diagnosis. The patient’s laboratory results displayed unremarkable antinuclear antibodies, creatine kinase, aldolase, and extractable nuclear antigens, which made connective tissue disease unlikely. Furthermore, a porphyria screen for total plasma porphyrins and whole blood protoporphyrin was negative, which helped rule out porphyria. Allergic contact dermatitis seemed less likely given the lack of improvement with topical steroids. Overall, the clinical presentation in a patient with relevant family ancestry and HLA-DR4 positivity supported a diagnosis of actinic prurigo.⁷

To manage the condition in our patient, strict photoprotection was recommended as well as the application of triamcinolone ointment 0.025% to the affected areas twice daily until the skin symptoms improved. For acute flares, other treatment considerations include topical tacrolimus, oral antihistamines, and oral corticosteroids. Some success has been reported with cyclosporine and azathioprine. For severe disease, thalidomide is the recommended treatment; it is effective in pediatric patients at dosages of 50 to 100 mg daily, but the dose has not yet been standardized for this age group.^8,9 Many adult patients initially are controlled with 100 to 200 mg daily, which can be tapered down to a dosage of 25 to 50 mg weekly with few adverse effects; however, the overall substantial side effects of thalidomide limit its use in both pediatric and adult populations.^1,2 Newer studies have suggested promising results with dupilumab, especially when actinic prurigo presents with high IgE levels or eosinophils on histology.^7,10 In our patient, the IgE level was normal.

For acute flares, other treatment considerations include topical tacrolimus, oral antihistamines, and oral corticosteroids. Some success has been reported with cyclosporine and azathioprine. For severe disease, thalidomide is the recommended treatment; it is effective in pediatric patients at dosages of 50 to 100 mg daily, but the dose has not yet been standardized for this age group.^8,9 Many adult patients initially are controlled with 100 to 200 mg daily, which can be tapered down to a dosage of 25 to 50 mg weekly with few adverse effects; however, the overall substantial side effects of thalidomide limit its use in both pediatric and adult populations.^1,2 Newer studies have suggested promising results with dupilumab, especially when actinic prurigo presents with high IgE levels or eosinophils on histology.^7,10 In our patient, the IgE level was normal.

MANNHEIM, GERMANY – Contrary to expectations, individuals with familial hypercholesterolemia (FH) have rates of overweight and obesity that mirror the general population – rates that appear to have a substantial impact on these patients’ already increased risk of coronary artery disease, a registry analysis suggests.

Data on almost 36,000 individuals with FH were collated from an international registry, revealing that 55% of adults and 25% of children and adolescents with the homozygous form of FH had overweight or obesity. The figures for heterozygous FH were 52% and 27%, respectively.

Crucially, overweight or obesity was associated with substantially increased rates of coronary artery disease, particularly in persons with heterozygous FH, among whom adults with obesity faced a twofold increased risk, rising to more than sixfold in children and adolescents.

Moreover, “obesity is associated with a worse lipid profile, even from childhood, regardless of whether a patient is on medication,” said study presenter Amany Elshorbagy, DPhil, Cardiovascular Epidemiologist, department of primary care and public health, Imperial College London.

She added that, with the increased risk of coronary artery disease associated with heterozygous FH, the results showed that “together with lipid-lowering medication, weight management is needed.”

The research was presented at the annual meeting of the European Atherosclerosis Society.
 

Tended to be thin

Alberico L. Catapano, MD, PhD, director of cardiovascular research and of the Lipoproteins and Atherosclerosis Laboratory of IRCCS Multimedica, Milan, and past president of the EAS, said in an interview that, historically, few FH patients were overweight or obese; rather, they tended to be thin.

However, there is now “a trend for people with FH to show more diabetes and obesity,” with the “bottom line” being that, as they are already at increased risk of coronary artery disease, it pushes their risk up even further.

In other words, if a risk factor such as obesity is added “on top of the strongest risk factor, that is LDL cholesterol, it is not one plus one makes two, it is one plus one makes three,” he said.

As such, Dr. Catapano believes that the study is “very interesting,” because it further underlines the importance of weight management for individuals with increased LDL cholesterol, “especially when you have genetic forms, like FH.”

Dr. Catapano’s comments were echoed by session co-chair Ulrike Schatz, MD, leader of the lipidology specialty department at the University Hospital Carl Gustav Carus, Technical University of Dresden (Germany).

Indeed, she told Dr. Elshorbagy before her presentation that she finds “a lot of my FH patients have a tendency towards anorexia.”

In an interview, Dr. Elshorbagy said that that reaction was typical of “most of the clinicians” she had spoken to. Upon seeing her data, especially for homozygous FH patients, they say, “They are on the lean side.”

Consequently, the research team went into the study “with the expectation that they might have a lower prevalence of obesity and overweight than the general population,” but “that’s not what we’re seeing.”

Dr. Elshorbagy noted that it would be helpful to have longitudinal data to determine whether, 50 years ago, patients with HF “were leaner, along with the rest of the population.”

The registry data are cross-sectional, and the team is now reaching out to the respective national lead investigators to submit follow-up data on their patients, with the aim of looking at changes in body weight and the impact on outcomes over time.

Another key question for the researchers is in regard to fat distribution, as body mass index “is not the best predictor of heart disease,” Dr. Elshorbagy said, but is rather central obesity.

Although they have also asked investigators to share waist circumference data, she conceded that it is a measurement that “is a lot harder to standardize across centers and countries; it’s not like putting patients on a scale.”

Overall, Dr. Elshorbagy believes that her findings indicate that clinicians should take a broader, more holistic approach toward their patients – in other words, an approach in which lipid lowering medication is “key but is just one of several things we need to do to make sure the coronary event rate goes down.”
 

More with than without

Dr. Elshorbagy began her presentation by highlighting that the prevalence of overweight and obesity ranges from 50% to 70% and that it is “the only health condition where you’ve got more people worldwide with the condition than without.”

Crucially, overweight increases the risk of coronary artery disease by approximately 20%. Among patients with obesity, the risk rises to 50%.

Given that FH patients “already have a very high risk of cardiovascular disease from their high cholesterol levels,” the team set out to determine rates of obesity and overweight in this population and their impact on coronary artery disease risk.

They used cross-sectional data from the EAS FH Studies Collaboration Global Registry, which involves 29,262 adults aged greater than or equal to 18 years and 6,275 children and adolescents aged 5 to 17 years with heterozygous FH, and 325 adults and 57 children with homozygous FH.

Dividing the adults into standard BMI categories, they found that 16% of heterozygous and 23% of homozygous FH patients had obesity, while 52% and 55%, respectively, had overweight or obesity.

For children, the team used World Health Organization z score cutoffs, which indicated that 9% of patients with heterozygous FH and 7% of patients with homozygous FH had obesity. Rates of overweight or obesity were 27% and 25%, respectively.

Among patients with heterozygous FH, rates of overweight or obesity among adults were 50% in high-income countries and 63% in other countries; among children, the rates were and 27% and 29%, respectively.

Stratified by region, the team found that the lowest rate of overweight or obesity among adult patients with heterozygous FH was in Eastern Asia, at 27%, while the highest was in Northern Africa/Western Asia (the Middle East), at 82%.

In North America, 56% of adult patients had overweight or obesity. The prevalence of coronary artery disease rose with increasing BMI.

Among adult patients with heterozygous FH, 11.3% of those with normal weight had coronary artery disease; the percentage rose to 22.9% among those with overweight, and 30.9% among those with obesity. Among children, the corresponding figures were 0.1%, 0.2%, and 0.7%.

Putting adults and children with homozygous FH together, the researchers found that 29.0% of patients with normal weight had coronary artery disease, compared with 31.3% of those with overweight and 49.3% of those with obesity.

Moreover, the results showed that levels of LDL and remnant cholesterol were significantly associated with BMI in adults and children with heterozygous FH, even after adjusting for age, sex, and lipid-lowering medication (P < .001 for all).

Multivariate analysis that took into account age, sex, lipid-lowering medication, and LDL cholesterol revealed that having obesity, compared with not having obesity, was associated with a substantial increase in the risk of coronary artery disease among patients with heterozygous FH.

Among adults with the condition, the odds ratio was 2.16 (95% confidence interval, 1.97-2.36), while among children and adolescents, it was 6.87 (95% CI, 1.55-30.46).

The results remained similar after further adjustment for the presence of diabetes and when considering peripheral artery disease and stroke.

No funding for the study was declared. Dr. Elshorbagy has relationships with Amgen, Daiichi Sankyo, and Regeneron.

An analysis of 61 cities in the United States where employers allow paid work absences for preventive medical services, such as breast and colon cancer screenings, shows that having the option of paid leave does in fact influence one’s decision to have preventive cancer screenings.

“Our results provide evidence for policymakers considering legislative or regulatory solutions to address insufficient screening adherence and highlight an understudied benefit of expanding paid sick leave coverage,” wrote authors who were led by Kevin Callison, PhD, of the Tulane University School of Public Health and Tropical Medicine, New Orleans.

The findings were published earlier this year in the New England Journal of Medicine.

Despite an Affordable Care Act provision eliminating most cost-sharing for cancer screening, the rate for recommended breast and colorectal cancer screening among U.S. adults is lower than 70%. Work commitments, time constraints, and the prospect of lost wages are frequently cited as contributing factors to this underuse of preventive care. Researchers hypothesized that having paid sick leave coverage for the use of preventive services could improve adherence to cancer screening guidelines. With continued failure to pass a bill mandating federal paid sick leave legislation, nearly 30% of the nation’s workforce lacks this coverage. Rates are lower for low-income workers, women, and underserved racial and ethnic groups, the authors write.

Coverage mandates have become politically contentious, as evidenced by the fact that their passage by some states (n = 17), counties (n = 4) and cities (n = 18) has been met by many states (n = 18) passing preemption laws banning municipalities from adopting the laws.

In this study, researchers examined the rate of colorectal and breast cancer screening at 12- and 24-month intervals among people living in one of 61 cities. Before paid sick leave mandates were put in place, cancer screening rates were similar across the board. But once mandates were put in place, cancer screening rates were higher among workers affected by the mandate by 1.31% (95% confidence interval, 0.28-2.34) for 12-month colorectal cancer screening, 1.56% (95% CI, 0.33-2.79) for 24-month colorectal cancer screening, 1.22% (95% CI, −0.20 to 2.64) for 12-month mammography, and 2.07% (95% CI, 0.15-3.99) for 24-month mammography.

“Although these appear to be modest effects, spread across a large population, these indicate a fairly substantial gain in cancer screenings,” Dr. Callison said.

Prior studies showing positive associations between having paid sick leave coverage and whether someone receives cancer screenings are likely confounded by selection bias because they compare workers who have such coverage to those who do not, Dr. Callison and colleagues state in their paper.

“Although the lack of paid sick leave coverage may hinder access to preventive care, current evidence is insufficient to draw meaningful conclusions about its relationship to cancer screening,” the authors write, citing that particularly health conscious workers may take jobs offering sick leave coverage.

Through quasi-experimental design, the present study aimed to overcome such confounding issues. Its analytic sample, using administrative data from the Merative MarketScan Research Databases, encompassed approximately 2.5 million person-specific records per year for the colorectal cancer screening sample. The researchers’ mammography sample included 1.3 million person-specific records per year of the period examined.

The associations cited above translate into relative colorectal cancer screening increases of 8.1% in the 12-month adjusted model and a 5.9% relative increase from the premandate rate in the 24-month adjusted model. The rate was 1.56 percentage points (95% CI, 0.33-2.79) higher in the cities subject to the paid sick leave mandates (a 5.9% relative increase from the premandate rate). For screening mammography in the cities subject to the mandates, the 12-month adjusted 1.22% increase (95% CI, –0.20 to 2.64) represented a 2.5% relative increase from the premandate level. The adjusted 24-month rate increase of 2.07% (95% CI, 0.15-4.00) represented a 3.3% relative increase from premandate rates.

“However, these estimates are averages across all workers in our sample, many of whom likely already had paid sick leave coverage prior to the enactment of a mandate,” Dr. Callison said in the interview. “In fact, in other work related to this project, we estimated that about 28% of private sector workers gain paid sick leave when a mandate is enacted. So then, if we scale our findings by the share of workers actually gaining paid sick leave coverage, our estimates are much larger – a 9%-12% increase in screening mammography and a 21%-29% increase in colorectal cancer screening.”

Dr. Callison and his team are in the process of developing a follow-up proposal that would examine the effects of paid sick leave on downstream outcomes of the cancer care continuum, such as timing from diagnosis to treatment initiation. “We also hope to examine who benefits from these additional screens and what they mean for health equity. Data limitations prevented us from exploring that issue in the current study,” he said.

Dr. Callison had no conflicts associated with this study.

Work commitments, time constraints, and the prospect of lost wages are frequently cited as contributing factors to this underuse of preventive care. Researchers hypothesized that having paid sick leave coverage for the use of preventive services could improve adherence to cancer screening guidelines. With continued failure to pass a bill mandating federal paid sick leave legislation, nearly 30% of the nation’s workforce lacks this coverage. Rates are lower for low-income workers, women, and underserved racial and ethnic groups, the authors write.

Coverage mandates have become politically contentious, as evidenced by the fact that their passage by some states (n = 17), counties (n = 4) and cities (n = 18) has been met by many states (n = 18) passing preemption laws banning municipalities from adopting the laws.

In this study, researchers examined the rate of colorectal and breast cancer screening at 12- and 24-month intervals among people living in one of 61 cities. Before paid sick leave mandates were put in place, cancer screening rates were similar across the board. But once mandates were put in place, cancer screening rates were higher among workers affected by the mandate by 1.31% (95% confidence interval, 0.28-2.34) for 12-month colorectal cancer screening, 1.56% (95% CI, 0.33-2.79) for 24-month colorectal cancer screening, 1.22% (95% CI, −0.20 to 2.64) for 12-month mammography, and 2.07% (95% CI, 0.15-3.99) for 24-month mammography.

“Although these appear to be modest effects, spread across a large population, these indicate a fairly substantial gain in cancer screenings,” Dr. Callison said.

Prior studies showing positive associations between having paid sick leave coverage and whether someone receives cancer screenings are likely confounded by selection bias because they compare workers who have such coverage to those who do not, Dr. Callison and colleagues state in their paper.

“Although the lack of paid sick leave coverage may hinder access to preventive care, current evidence is insufficient to draw meaningful conclusions about its relationship to cancer screening,” the authors write, citing that particularly health conscious workers may take jobs offering sick leave coverage.

Through quasi-experimental design, the present study aimed to overcome such confounding issues. Its analytic sample, using administrative data from the Merative MarketScan Research Databases, encompassed approximately 2.5 million person-specific records per year for the colorectal cancer screening sample. The researchers’ mammography sample included 1.3 million person-specific records per year of the period examined.

The associations cited above translate into relative colorectal cancer screening increases of 8.1% in the 12-month adjusted model and a 5.9% relative increase from the premandate rate in the 24-month adjusted model. The rate was 1.56 percentage points (95% CI, 0.33-2.79) higher in the cities subject to the paid sick leave mandates (a 5.9% relative increase from the premandate rate). For screening mammography in the cities subject to the mandates, the 12-month adjusted 1.22% increase (95% CI, –0.20 to 2.64) represented a 2.5% relative increase from the premandate level. The adjusted 24-month rate increase of 2.07% (95% CI, 0.15-4.00) represented a 3.3% relative increase from premandate rates.

“However, these estimates are averages across all workers in our sample, many of whom likely already had paid sick leave coverage prior to the enactment of a mandate,” Dr. Callison said in the interview. “In fact, in other work related to this project, we estimated that about 28% of private sector workers gain paid sick leave when a mandate is enacted. So then, if we scale our findings by the share of workers actually gaining paid sick leave coverage, our estimates are much larger – a 9%-12% increase in screening mammography and a 21%-29% increase in colorectal cancer screening.”

Dr. Callison and his team are in the process of developing a follow-up proposal that would examine the effects of paid sick leave on downstream outcomes of the cancer care continuum, such as timing from diagnosis to treatment initiation. “We also hope to examine who benefits from these additional screens and what they mean for health equity. Data limitations prevented us from exploring that issue in the current study,” he said.

Dr. Callison had no conflicts associated with this study.

CHICAGO – The regular use of aspirin or other nonsteroidal anti-inflammatory drugs was found to be associated with a lower risk of early-onset conventional and advanced adenomas. The authors say that aspirin could prove to be an effective strategy in preventing early-onset colorectal cancer cases.

“What we have here is a 15% reduction for all adenomas and 33% for those with advanced histology, which to us is quite substantial. We have not seen that much [33%] in previous studies so I would think it definitely needs more study,” said Cassandra D. Fritz, MD, MPHS, a gastroenterologist with Washington University, St. Louis, in an oral presentation given at the annual Digestive Disease Week^®.

“This finding is important given the alarming rise in the incidence and mortality of early-onset colorectal cancer (age < 50 years), and our limited understanding of the underlying drivers to direct prevention efforts,” Dr. Fritz said. Early-onset colorectal cancer cases have doubled since 1995, she said.

The study confirms evidence from 30 years of research that suggests regular aspirin use reduces cancer risk. In patients with Lynch syndrome, the CAPP2 study showed that aspirin has a protective effect against colorectal cancer at 20 years follow-up.

While emerging data have suggested that aspirin use may reduce later-onset colorectal cancer, it was not known if regular aspirin and NSAID use are associated with diminished risk of early-onset conventional adenomas, and especially the high-risk adenomas conferring greater malignant potential known to be the major precursor of early-onset colorectal cancer. An unpublished analysis of molecular markers by the study’s senior author, Yin Cao, ScD, MPH, also of Washington University, found that at least 57% of early-onset colorectal cancers developed from the conventional adenoma-carcinoma pathway.

The objective of the new study was to assess the association between regular aspirin or NSAID use at least twice weekly, with the risk of developing early-onset adenoma. The analysis is based on an evaluation of data from the Nurses’ Health Study II of 32,058 women who had at least one colonoscopy before age 50 (1991-2015). High-risk adenomas included those that were at least 1 cm with tubulovillous/villous histology or high-grade dysplasia, or the presence of at least three adenomas.

There were 1,247 early-onset adenomas, among which 290 were considered high risk. The risk of adenomas among patients who took aspirin or NSAIDs regularly for cardiovascular protection or for inflammatory conditions, was lower than in those who did not take aspirin and/or NSAIDs regularly. While the association was similar for high-risk vs. low-risk adenomas, the benefit was more pronounced for adenomas of tubulovillous/villous histology or with high-grade dysplasia (odds ratio, 0.67; 95% confidence interval, 0.51-0.89), a 33% reduction, compared with tubular adenomas (OR, 0.90; 95% CI, 0.79-1.0; P for heterogeneity = .02).

With later-onset adenomas, risk reduction was confined primarily to large (OR, 0.76; 95% CI, 0.62-0.93) or multiple adenomas (OR, 0.57; 95% CI, 0.40-0.83), but not adenomas of advanced histology (OR, 0.92; 95% CI, 0.73-1.17).

“With colorectal cancer rates increasing, we still don’t have any preventative strategies beyond screening. With this 15% reduction with aspirin/NSAIDS in early-onset adenoma – and particularly for the quite substantial 33% benefit in advanced adenoma with advanced histology, we need to think about a precision-based chemoprevention strategy for early-onset precursors of colorectal cancer,” Dr. Cao said.

The U.S. Preventive Services Task Force issued a new recommendation in 2021 stating that colorectal cancer screening for people with average risk should start 5 years sooner at age 45. “As we know,” Dr. Yin said, “many younger adults are not screened. That’s why we’re looking into potential early-onset colorectal cancer chemopreventative agents.”
