The Food and Drug Administration has approved the anti-inflammatory drug colchicine 0.5 mg tablets (Lodoco) as the first specific anti-inflammatory drug demonstrated to reduce the risk for myocardial infarction, stroke, coronary revascularization, and cardiovascular death in adult patients with established atherosclerotic disease or with multiple risk factors for cardiovascular disease.

The drug, which targets residual inflammation as an underlying cause of atherosclerotic cardiovascular disease, has a dosage of 0.5 mg once daily, and can be used alone or in combination with cholesterol-lowering medications.

The drug’s manufacturer, Agepha Pharma, said it anticipates that Lodoco will be available for prescription in the second half of 2023.

Colchicine has been available for many years and used at higher doses for the acute treatment of gout and pericarditis, but the current formulation is a much lower dose for long-term use in patients with atherosclerotic heart disease.

Data supporting the approval has come from two major randomized trials, LoDoCo-2 and COLCOT.

In the LoDoCo-2 trial, the anti-inflammatory drug cut the risk of cardiovascular events by one third when added to standard prevention therapies in patients with chronic coronary disease. And in the COLCOT study, use of colchicine reduced cardiovascular events by 23% compared with placebo in patients with a recent MI. 

Paul Ridker, MD, director of the Center for Cardiovascular Disease Prevention at Brigham and Women’s Hospital in Boston, who has been a pioneer in establishing inflammation as an underlying cause of atherosclerotic cardiovascular disease, welcomed the Lodoco approval.
 

‘A very big day for cardiology’

“This is a very big day for cardiology,” Dr. Ridker said in an interview.

“The FDA approval of colchicine for patients with atherosclerotic disease is a huge signal that physicians need to be aware of inflammation as a key player in cardiovascular disease,” he said.

Dr. Ridker was the lead author of a recent study showing that among patients receiving contemporary statins, inflammation assessed by high-sensitivity C-reactive protein (hsCRP) was a stronger predictor for risk of future cardiovascular events and death than LDL cholesterol.

He pointed out that the indication for Lodoco was very broad, simply stating that it can be used in adult patients with established atherosclerotic disease or with multiple risk factors for cardiovascular disease.

“That is virtually identical to the indication approved for statin therapy. That shows just how important the FDA thinks this is,” he commented.

But Dr. Ridker added that, while the label does not specify that Lodoco has to be used in addition to statin therapy, he believes that it will be used as additional therapy to statins in the vast majority of patients.

“This is not an alternative to statin therapy. In the randomized trials, the benefits were seen on top of statins,” he stressed.

Dr. Ridker believes that physicians will need time to feel comfortable with this new approach. 

“Initially, I think, it will be used mainly by cardiologists who know about inflammation, but I believe over time it will be widely prescribed by internists, in much the same way as statins are used today,” he commented.

Dr. Ridker said he already uses low dose colchicine in his high-risk patients who have high levels of inflammation as seen on hsCRP testing. He believes this is where the drug will mostly be used initially, as this is where it is likely to be most effective.

The prescribing information states that Lodoco is contraindicated in patients who are taking strong CYP3A4 inhibitors or P-glycoprotein inhibitors, such as ketoconazole, fluconazole, and clarithromycin, and in patients with preexisting blood dyscrasias, renal failure, and severe hepatic impairment.

Common side effects reported in published clinical studies and literature with the use of colchicine are gastrointestinal symptoms (diarrhea, vomiting, abdominal cramping) and myalgia.

More serious adverse effects are listed as blood dyscrasias such as myelosuppression, leukopenia, granulocytopenia, thrombocytopenia, pancytopenia, and aplastic anemia; and neuromuscular toxicity in the form of myotoxicity including rhabdomyolysis, which may occur, especially in combination with other drugs known to cause this effect. If these adverse effects occur, it is recommended that the drug be stopped.

The prescribing information also notes that Lodoco may rarely and transiently impair fertility in males; and that patients with renal or hepatic impairment should be monitored closely for adverse effects of colchicine.

NAFLD increases risk for severe infections

Article Type
Changed
Mon, 06/26/2023 - 08:40

People with nonalcoholic fatty liver disease (NAFLD) are more likely to develop severe infections requiring hospitalization, according to findings from a large Swedish cohort study.

The increased risk was equal to one extra severe infection in every six patients with NAFLD by 20 years after diagnosis, wrote Fahim Ebrahimi, MD, of the Karolinska Institute in Stockholm, and coauthors.

“Accumulating evidence suggests that NAFLD can affect multiple organ systems, which is not surprising, as the liver has multiple functions – regulating metabolism and being a central organ of the immune system,” Dr. Ebrahimi said in an interview.

The study was published online in Clinical Gastroenterology and Hepatology.

“Up to a fifth of cells in the liver are immune cells that process numerous antigens and pathogens from the gastrointestinal tract,” Dr. Ebrahimi noted. “We were intrigued by experimental studies showing that, in NAFLD, many of these key immune cells become dysfunctional at various levels, which may affect disease progression, but at the same time also increase the susceptibility to viral, bacterial, and fungal infections.”

Patients with NAFLD have metabolic risk factors known to increase infection risk, but a smaller study by a different research group had found that NAFLD could independently predispose patients to bacterial infections.

To further explore a connection between NAFLD and infection risk, the researchers looked at data for 12,133 Swedish adults with simple steatosis, nonfibrotic steatohepatitis, noncirrhotic fibrosis, or cirrhosis caused by NAFLD confirmed by liver biopsies performed between 1969 and 2017.

Each patient was matched to five or more contemporary controls from the general population by age, sex, and region of residence. The authors conducted an additional analysis that also adjusted for education, country of birth, and baseline clinical comorbidities, including diabetes, obesity, dyslipidemia, and hypertension, as well as hospitalization preceding the biopsy and chronic obstructive pulmonary disease.

The primary endpoint was severe infections requiring hospital admission. Secondary endpoints included seven prespecified infection subgroups: sepsis; respiratory tract; most gastrointestinal infections; bacterial peritonitis; urogenital; muscle, skin, and soft tissue; and other infections.
 

Elevated risk at all NAFLD stages

Dr. Ebrahimi and colleagues found that over a median follow-up of 14 years, patients with NAFLD had a higher incidence of severe infections – most often respiratory or urinary tract infections – compared with those without NAFLD (32% vs. 17%, respectively).

Biopsy-confirmed NAFLD was also associated with a 71% higher hazard and a 20-year absolute excess risk of 17.3% for severe infections requiring hospital admission versus comparators. The elevated risk showed up in patients with steatosis and increased with the severity of NAFLD. Simple steatosis saw a 64% higher risk (adjusted hazard ratio, 1.64; 95% confidence interval, 1.55-1.73), whereas patients with cirrhosis saw a more than twofold higher risk, compared with controls (aHR, 2.32; 95% CI, 1.92-2.82).

When Dr. Ebrahimi and colleagues adjusted for parameters of the metabolic syndrome, they found an independent increased risk for severe infection. For patients with NAFLD, the increased risk may come from greater susceptibility to infections in general or to a more severe course of infections.

“Our study clearly demonstrates the complexity and high disease burden associated with NAFLD,” Dr. Ebrahimi said. “We are beginning to understand the different layers involved and will eventually move away from a liver-centric view to a more holistic view of the disease.”

Clinicians caring for patients with NAFLD need to be aware of the increased risk for infection, Dr. Ebrahimi said. They also should assess their patients’ vaccination status, and seek to control modifiable risk factors, such as diabetes.

Nancy Reau, MD, of Rush University, Chicago, described the study’s message as important.

“Patients with NAFLD and advancing liver disease are at risk for severe infections,” Dr. Reau said. “When we consider the fact that patients with advanced liver disease tend to die from infectious complications, awareness leading to early recognition and efficient treatment is imperative.”

The authors acknowledged the following limitations: only severe infections requiring hospitalization could be captured; whether infection led to decompensation or vice versa among patients with cirrhosis could not be determined; and detailed data on smoking, alcohol, vaccinations, body mass, and other potentially relevant measures were not available.

The Swiss National Science Foundation, Syskonen Svensson Foundation, and Bengt Ihre Foundation provided grants to Dr. Ebrahimi or coauthors. One coauthor disclosed previous research funding from Janssen and MSD. Dr. Reau disclosed receiving research support and consulting fees from AbbVie and Gilead, as well as consulting fees from Arbutus, Intercept, and Salix.

Aspirin warning: Anemia may increase with daily use

Article Type
Changed
Tue, 06/27/2023 - 12:20

Older people who take daily low-dose aspirin have at 20% higher risk of developing anemia even without having already had a major bleeding event, according to results from a new randomized controlled trial.

In the study, which was published in Annals of Internal Medicine, investigators analyzed data from the Aspirin in Reducing Events in the Elderly (ASPREE) trial and examined hemoglobin concentrations among 19,114 healthy, community-dwelling older patients.

“We knew from large clinical trials, including our ASPREE trial, that daily low-dose aspirin increased the risk of clinically significant bleeding,” said Zoe McQuilten, MBBS, PhD, a hematologist at Monash University in Australia and the study’s lead author. “From our study, we found that low-dose aspirin also increased the risk of anemia during the trial, and this was most likely due to bleeding that was not clinically apparent.”

Anemia is common among elderly patients. It can cause fatigue, fast or irregular heartbeat, headache, chest pain, and pounding or whooshing sounds in the ear, according to the Cleveland Clinic. It can also worsen conditions such as heart failure, cognitive impairment, and depression in people aged 65 and older.

The U.S. Preventive Services Task Force changed its recommendation on aspirin for the primary prevention of cardiovascular disease in 2022, recommending against initiating low-dose aspirin for adults aged 60 years or older. For adults aged 40-59 who have a 10% or greater 10-year risk for cardiovascular disease, the agency recommends that patients and clinicians make the decision to initiate low-dose aspirin use on a case-by-case basis, as the net benefit is small.

Dr. McQuilten said she spent the last 5 years designing substages of anemia and conditions such as blood cancer. In many cases of anemia, doctors are unable to determine the underlying cause, she said. One study published in the Journal of American Geriatrics Society in 2021 found that in about one-third of anemia cases, the etiology was not clear.

About 50% of people older than 60 who were involved in the latest study took aspirin for prevention from 2011 to 2018. That number likely dropped after changes were made to the guidelines in 2022, according to Dr. McQuilten, but long-term use may have continued among older patients. The researchers also examined ferritin levels, which serve as a proxy for iron levels, at baseline and after 3 years.

The incidence of anemia was 51 events per 1,000 person-years in the aspirin group compared with 43 events per 1,000 person-years in the placebo group, according to the researchers. The estimated probability of experiencing anemia within 5 years was 23.5% (95% confidence interval [CI], 22.4%-24.6%) in the aspirin group and 20.3% (95% CI: 19.3% to 21.4%) in the placebo group. Aspirin therapy resulted in a 20% increase in the risk for anemia (95% CI, 1.12-1.29).

People who took aspirin were more likely to have lower serum levels of ferritin at the 3-year mark than were those who received placebo. The average decrease in ferritin among participants who took aspirin was 11.5% greater (95% CI, 9.3%-13.7%) than among those who took placebo.

Basil Eldadah, MD, PhD, supervisory medical officer at the National Institute on Aging, part of the National Institutes of Health, said the findings should encourage clinicians to pay closer attention to hemoglobin levels and have conversations with patients to discuss their need for taking aspirin.

“If somebody is already taking aspirin for any reason, keep an eye on hemoglobin,” said Dr. Eldadah, who was not involved in the study. “For somebody who’s taking aspirin and who’s older, and it’s not for an indication like cardiovascular disease, consider seriously whether that’s the best treatment option.”

The study did not examine the functional consequences of anemia on participants, which Dr. Eldadah said could be fodder for future research. The researchers said one limitation was that it was not clear whether anemia was sufficient to cause symptoms that affected participants’ quality of life or whether occult bleeding caused the anemia. The researchers also did not document whether patients saw their regular physicians and received treatment for anemia over the course of the trial.

The study was funded through grants from the National Health and Medical Research Council and the Bill and Melinda Gates Foundation. The authors reported receiving consulting fees, honoraria, and stock options, and have participated on data monitoring boards not related to the study for Vifor Pharma, ITL Biomedical, Pfizer, Boehringer Ingelheim, Bayer Healthcare, AbbVie, and Abbott Diagnostics.

The U.S. Preventive Services Task Force changed its recommendation on aspirin for the primary prevention of cardiovascular disease in 2022, recommending against initiating low-dose aspirin for adults aged 60 years or older. For adults aged 40-59 who have a 10% or greater 10-year risk for cardiovascular disease, the agency recommends that patients and clinicians make the decision to initiate low-dose aspirin use on a case-by-case basis, as the net benefit is small.

Dr. McQuilten said she spent the last 5 years designing substages of anemia and conditions such as blood cancer. In many cases of anemia, doctors are unable to determine the underlying cause, she said. One study published in the Journal of American Geriatrics Society in 2021 found that in about one-third of anemia cases, the etiology was not clear.

About 50% of people older than 60 who were involved in the latest study took aspirin for prevention from 2011 to 2018. That number likely dropped after changes were made to the guidelines in 2022, according to Dr. McQuilten, but long-term use may have continued among older patients. The researchers also examined ferritin levels, which serve as a proxy for iron levels, at baseline and after 3 years.

The incidence of anemia was 51 events per 1,000 person-years in the aspirin group compared with 43 events per 1,000 person-years in the placebo group, according to the researchers. The estimated probability of experiencing anemia within 5 years was 23.5% (95% confidence interval [CI], 22.4%-24.6%) in the aspirin group and 20.3% (95% CI: 19.3% to 21.4%) in the placebo group. Aspirin therapy resulted in a 20% increase in the risk for anemia (95% CI, 1.12-1.29).

People who took aspirin were more likely to have lower serum levels of ferritin at the 3-year mark than were those who received placebo. The average decrease in ferritin among participants who took aspirin was 11.5% greater (95% CI, 9.3%-13.7%) than among those who took placebo.

Basil Eldadah, MD, PhD, supervisory medical officer at the National Institute on Aging, part of the National Institutes of Health, said the findings should encourage clinicians to pay closer attention to hemoglobin levels and have conversations with patients to discuss their need for taking aspirin.

“If somebody is already taking aspirin for any reason, keep an eye on hemoglobin,” said Dr. Eldadah, who was not involved in the study. “For somebody who’s taking aspirin and who’s older, and it’s not for an indication like cardiovascular disease, consider seriously whether that’s the best treatment option.”

The study did not examine the functional consequences of anemia on participants, which Dr. Eldadah said could be fodder for future research. The researchers said one limitation was that it was not clear whether anemia was sufficient to cause symptoms that affected participants’ quality of life or whether occult bleeding caused the anemia. The researchers also did not document whether patients saw their regular physicians and received treatment for anemia over the course of the trial.

The study was funded through grants from the National Health and Medical Research Council and the Bill and Melinda Gates Foundation. The authors reported receiving consulting fees, honoraria, and stock options, and have participated on data monitoring boards not related to the study for Vifor Pharma, ITL Biomedical, Pfizer, Boehringer Ingelheim, Bayer Healthcare, AbbVie, and Abbott Diagnostics.

Older people who take daily low-dose aspirin have at 20% higher risk of developing anemia even without having already had a major bleeding event, according to results from a new randomized controlled trial.

In the study, which was published in Annals of Internal Medicine, investigators analyzed data from the Aspirin in Reducing Events in the Elderly (ASPREE) trial and examined hemoglobin concentrations among 19,114 healthy, community-dwelling older patients.

“We knew from large clinical trials, including our ASPREE trial, that daily low-dose aspirin increased the risk of clinically significant bleeding,” said Zoe McQuilten, MBBS, PhD, a hematologist at Monash University in Australia and the study’s lead author. “From our study, we found that low-dose aspirin also increased the risk of anemia during the trial, and this was most likely due to bleeding that was not clinically apparent.”

Hold Ozempic before surgery to optimize patient safety?

Article Type

Thu, 06/22/2023 - 14:40

Semaglutide and related drugs for weight loss have co-opted bariatric medicine in recent months. They have also raised serious questions for hospital-based clinicians who wonder whether the drugs may pose risks to surgery patients undergoing anesthesia.

Holding Ozempic (semaglutide) before elective surgery – and if so, for how long – remains largely a judgment call at this point. Official guidance on best practices has not yet caught up to surging popularity of this and other glucagon-like peptide-1 (GLP-1) agonists for weight loss.

Ozempic is indicated for treating type 2 diabetes but also is prescribed off-label for weight loss. Other GLP-1 agents from Novo Nordisk, Wegovy (semaglutide) and Saxenda (liraglutide) injections, are Food and Drug Administration–approved for weight loss. These medications work by decreasing hunger and lowering how much people eat. Semaglutide also is available as a once-daily tablet for type 2 diabetes (Rybelsus).

The American Society of Anesthesiologists (ASA) has been working on guidance on the drugs. “It’s a really hot issue now. We are getting emails from our members looking for guidance,” ASA president Michael Champeau, MD, said in an interview.

But despite the interest in how the medications might affect surgery patients and interact with anesthesia, relatively little evidence exists in the literature beyond case studies. So the society is not issuing official recommendations at this point.

“We’re going to just be calling it ‘guidance’ for right now because of the paucity of the scientific literature,” said Dr. Champeau, adjunct clinical professor of anesthesiology, perioperative, and pain medicine at Stanford (Calif.) University. “It’s probably not going to have words like ‘must; it will probably have words like ‘should’ or ‘should consider.’ “

The ASA guidance could be out in written form soon, Dr. Champeau added.

Meanwhile, whether physicians should advise stopping these medications 24 hours, 48 hours, or up to 2 weeks before surgery remains unknown.

In search of some consensus, John Shields, MD, an orthopedic surgeon at Atrium Health Wake Forest Baptist Davie Medical Center in Bermuda Run, N.C., asked colleagues on #MedTwitter: “Anyone have guidelines for ozempic around time of surgery? – holding med? – how long NPO?”

Because a full stomach can interfere with anesthesia, clinicians often advise people to stop eating and drinking 12-24 hours before elective procedures (NPO). In the case of once-weekly GLP-1 injections, which can slow gastric emptying, the optimal timeframe remains an open question. The main concern is aspiration, where a patient actively vomits while under anesthesia or their stomach contents passively come back up.

Dr. Shields’ Twitter post garnered significant reaction and comments. Within 4 days, the post was retweeted 30 times and received 72 replies and comments. Dr. Shields noted the general consensus was to hold semaglutide for 1-2 weeks before a procedure. Other suggestions included recommending a liquid diet only for 24-48 hours before surgery, recommending an NPO protocol 24-36 hours in advance, or adjusting the weekly injection so the last dose is taken 5-6 days before surgery.

Anesthesiologist Cliff Gevirtz, MD, has encountered only a few surgical patients so far taking a GLP-1 for weight loss. “And thankfully no aspiration,” added Dr. Gevirtz, clinical director of office-based ambulatory anesthesia services at Somnia Anesthesia in Harrison, N.Y.

To minimize risk, some physicians will perform an ultrasound scan to assess the contents of the stomach. If surgery is elective in a patient with a full stomach, the procedure can get postponed. Another option is to proceed with the case but treat the patient as anesthesiologists approach an emergency procedure. To be safe, many will treat the case as if the patient has a full stomach.

Dr. Gevirtz said he would treat the patient as a ‘full stomach’ and perform a rapid sequence induction with cricoid pressure. He would then extubate the patient once laryngeal reflexes return.

A rapid-sequence induction involves giving the medicine that makes a patient go to sleep, giving another medicine that paralyzes them quickly, then inserting a breathing tube – all within about 30 seconds. Cricoid pressure involves pushing on the neck during intubation to try to seal off the top of the esophagus and again minimize the chances of food coming back up.

Giving metoclopramide 30 minutes before surgery is another option, Dr. Gevirtz said. Metoclopramide can hasten the emptying of stomach contents. Administration in advance is important because waiting for the drug to work can prolong time in the operating room.

Is holding semaglutide before surgery a relevant clinical question? “Yes, very much so,” said Ronnie Fass, MD, division director of gastroenterology and hepatology and the medical director of the Digestive Health Center at The MetroHealth System in Cleveland.

Dr. Fass recommended different strategies based on the semaglutide indication. Currently, clinicians at MetroHealth instruct patients to discontinue diabetic medications the day of surgery. For those who take semaglutide for diabetes, and because the medication is taken once a week, “there is growing discussion among surgeons that the medication should not be stopped prior to surgery. This is to ensure that patients’ diabetes is well controlled before and during surgery,” Dr. Fass said.

In patients taking semaglutide for weight loss only, “there is no clear answer at this point,” he said.

Dr. Fass said the question is complicated by the fact that the medication is taken once a week. “It brings up important questions about the use of the medication during surgery, which may increase the likelihood of side effects in general and for certain types of surgery. Personally, if a patient is taking [semaglutide] for weight loss only, I would consider stopping the medication before surgery.”

The ASA was able to act quickly because it already had an expert task force review how long people should fast before surgery last year – before the explosion in popularity of the GLP-1 agonists.

Although it is still a work in progress, Dr. Champeau offered “a peek” at the recommendations. “The guidance is going to look at how far in advance the drugs should be stopped, rather than looking at making people fast even longer” before surgery, he said. “There’s just no data on that latter question.”

Docs misdiagnose aneurysm and patient dies; must pay $29M; more

Article Type
Changed
Tue, 06/20/2023 - 18:20

Two Boston doctors associated with Salem Hospital, a clinical affiliate of Massachusetts General Hospital, must pay nearly $29 million to the family of a man whose aortic aneurysm and dissection went undiagnosed and untreated, according to a story posted on Boston.com, among other news sites.

On the morning of Jan. 13, 2018, Joseph Brown awoke with shortness of breath and upper abdominal pain, which eventually spread to his chest and back. Taken to Salem Hospital’s emergency department, Mr. Brown was seen by Steven D. Browell, MD, an emergency medicine specialist.

Dr. Browell ordered tests that ruled out both a heart attack and a pulmonary embolism. He called for a blood test, which indicated that the patient’s white blood count was elevated. Suspecting an infection, Dr. Browell ordered that Mr. Brown be admitted to the hospital.

Accepting Mr. Brown’s admission was William D. Kenyon, MD, a hospitalist, who also examined the patient and concurred with Dr. Browell’s probable diagnosis. The patient was then sent to the medical floor.

There he underwent additional testing, including a chest x-ray, which proved negative except for one finding: a “mild hazy interstitial opacity that could represent a small airway inflammation or developing/early pneumonia.” Because Mr. Brown had reported that he had punctured his foot several days earlier, he also underwent a foot x-ray, which showed a possible foreign body. It was thought that might be the source of his infection.

Neither Dr. Browell nor Dr. Kenyon had completely ruled out a possible aortic aneurysm and dissection. Mr. Brown’s symptoms, after all, were in some ways suggestive of those conditions. Then again, he was very young – only 43 at the time – and his pain, while severe, didn’t correspond to the “searing” pain that, at trial, Dr. Kenyon described as typical of an aneurysm and dissection. As the hospitalist testified at trial, Mr. Brown had “a constellation of nonspecific symptoms” and an “unusual presentation of a rare condition,” typically seen in patients aged 65 and older.

Given these factors – and the results of Mr. Brown’s tests, lab studies, and physical exam – Dr. Kenyon didn’t think that the case warranted a CT scan to rule out an aortic aneurysm or aortic dissection.

By early the next morning, though, Mr. Brown’s shortness of breath and pain had intensified significantly. The on-duty doctor ordered a CT scan, which showed “a massive aneurysm at the beginning of [the patient’s] aorta and a dissection extending through most of his aorta.”

Mr. Brown was flown to Boston to undergo emergency surgery. En route to the helicopter, his aorta ruptured, stopping his heart and causing his death.

During the 8-day trial, each side introduced expert witnesses. Speaking for the plaintiffs, experts in cardiothoracic surgery and emergency medicine testified that the treating physicians were negligent in failing to order a CT scan on Jan. 13. Had they done so, the patient would have almost certainly undergone surgery earlier, which would have prevented his death.

Experts for the defense saw things differently. They testified that, given the evidence, it was reasonable and appropriate for Dr. Browell and Dr. Kenyon to have treated their patient for an infection rather than an aneurysm or dissection.

The jury found the defense’s arguments unconvincing, however. After deliberating 3 hours, it awarded the plaintiffs $20,000,000, to be paid out over time largely to Mr. Brown’s two daughters, who were aged 12 and 18 when he died. Including interest, the total award is close to $29 million.

In a statement following the verdict, lead plaintiff’s attorney Robert M. Higgins, of Lubin & Meyer, Boston, said the takeaway from the case was: “If you just treat people based on what the likelihood is, statistically, you’re going to miss a lot of life-threatening conditions. And that’s what happened in this case.”
 

 

 

Urologists typically prevail in BPH suits

Malpractice claims following surgery for benign prostatic hyperplasia (BPH) tend to be limited in scope and are typically resolved in favor of the surgeon-defendant, as a study in The Cureus Journal of Medical Science makes clear.

The study – conducted by a team of researchers that included Joao G. Porto, MD, of the Desai Sethi Urology Institute, University of Miami – investigated whether such surgeries pose a significant malpractice risk for urologists.

With information gleaned from two well-known legal databases, the team used a variety of key terms to identify BPH-related claims from January 2000 to December 2021.

Within this universe of claims, researchers identified several significant trends:

  • Among BPH-related procedures, transurethral resection of the prostate was the most frequently identified (37%);
  • Among the most-often cited reasons cited for a claim, allegations of inadequate postoperative care were the most common (33%);
  • Of possible postsurgical complications, those that led to the greatest number of suits were urinary incontinence (23%), erectile dysfunction (13%), and urinary retention (13%); and,
  • Not unexpectedly, the specialist most frequently named in a suit was a urologist (57%).

Interestingly, in all but two of the claims, the verdict favored the doctor-defendant. In the two cases in which the plaintiff prevailed, each involved unexpected and serious postsurgical complications.

Accepting Mr. Brown’s admission was William D. Kenyon, MD, a hospitalist, who also examined the patient and concurred with Dr. Browell’s probable diagnosis. The patient was then sent to the medical floor.

There he underwent additional testing, including a chest x-ray, which proved negative except for one finding: a “mild hazy interstitial opacity that could represent a small airway inflammation or developing/early pneumonia.” Because Mr. Brown had reported that he had punctured his foot several days earlier, he also underwent a foot x-ray, which showed a possible foreign body. It was thought that might be the source of his infection.

Neither Dr. Browell nor Dr. Kenyon had completely ruled out a possible aortic aneurysm and dissection. Mr. Brown’s symptoms, after all, were in some ways suggestive of those conditions. Then again, he was very young – only 43 at the time – and his pain, while severe, didn’t correspond to the “searing” pain that, at trial, Dr. Kenyon described as typical of an aneurysm and dissection. As the hospitalist testified at trial, Mr. Brown had “a constellation of nonspecific symptoms” and an “unusual presentation of a rare condition,” typically seen in patients aged 65 and older.

Given these factors – and the results of Mr. Brown’s tests, lab studies, and physical exam – Dr. Kenyon didn’t think that the case warranted a CT scan to rule out an aortic aneurysm or aortic dissection.

By early the next morning, though, Mr. Brown’s shortness of breath and pain had intensified significantly. The on-duty doctor ordered a CT scan, which showed “a massive aneurysm at the beginning of [the patient’s] aorta and a dissection extending through most of his aorta.”

Mr. Brown was flown to Boston to undergo emergency surgery. En route to the helicopter, his aorta ruptured, stopping his heart and causing his death.

During the 8-day trial, each side introduced expert witnesses. Speaking for the plaintiffs, experts in cardiothoracic surgery and emergency medicine testified that the treating physicians were negligent in failing to order a CT scan on Jan. 13. Had they done so, the patient would have almost certainly undergone surgery earlier, which would have prevented his death.

Experts for the defense saw things differently. They testified that, given the evidence, it was reasonable and appropriate for Dr. Browell and Dr. Kenyon to have treated their patient for an infection rather than an aneurysm or dissection.

The jury found the defense’s arguments unconvincing, however. After deliberating 3 hours, it awarded the plaintiffs $20,000,000, to be paid out over time largely to Mr. Brown’s two daughters, who were aged 12 and 18 when he died. Including interest, the total award is close to $29 million.

In a statement following the verdict, lead plaintiff’s attorney Robert M. Higgins, of Lubin & Meyer, Boston, said the takeaway from the case was: “If you just treat people based on what the likelihood is, statistically, you’re going to miss a lot of life-threatening conditions. And that’s what happened in this case.”
 

 

 

Urologists typically prevail in BPH suits

Malpractice claims following surgery for benign prostatic hyperplasia (BPH) tend to be limited in scope and are typically resolved in favor of the surgeon-defendant, as a study in The Cureus Journal of Medical Science makes clear.

The study – conducted by a team of researchers that included Joao G. Porto, MD, of the Desai Sethi Urology Institute, University of Miami – investigated whether such surgeries pose a significant malpractice risk for urologists.

With information gleaned from two well-known legal databases, the team used a variety of key terms to identify BPH-related claims from January 2000 to December 2021.

Within this universe of claims, researchers identified several significant trends:

  • Among BPH-related procedures, transurethral resection of the prostate was the most frequently identified (37%);
  • Among the most-often cited reasons cited for a claim, allegations of inadequate postoperative care were the most common (33%);
  • Of possible postsurgical complications, those that led to the greatest number of suits were urinary incontinence (23%), erectile dysfunction (13%), and urinary retention (13%); and,
  • Not unexpectedly, the specialist most frequently named in a suit was a urologist (57%).

Interestingly, in all but two of the claims, the verdict favored the doctor-defendant. In the two cases in which the plaintiff prevailed, each involved unexpected and serious postsurgical complications.

Two Boston doctors associated with Salem Hospital, a clinical affiliate of Massachusetts General Hospital, must pay nearly $29 million to the family of a man whose aortic aneurysm and dissection went undiagnosed and untreated, according to a story posted on Boston.com, among other news sites.

Interventional cardiologists worldwide burned out: Survey

Article Type
Changed
Wed, 06/21/2023 - 08:48

Interventional cardiologists (ICs) around the world are unhappy and burned out, and their well-being is compromised, a new international survey suggests.

“What surprised me was the magnitude of the findings,” Emmanouil S. Brilakis, MD, PhD of the Minneapolis Heart Institute and Minneapolis Heart Institute Foundation, said in an interview.

“I was expecting that some interventionalists would feel burned out, but not that 78% would feel they are working too hard, 64% are emotionally exhausted, and 41% considered quitting their job during the past year.

The survey, conducted in January, also showed that while 69% of respondents were affected by burnout, many were either not seeking mental health support or not willing to share whether they were under treatment.

Overall, 28% of interventional cardiologists were not happy with their lives, similar to the 29% reported in the Medscape Cardiologist Lifestyle, Happiness & Burnout Report 2022.

“Many institutions have formed task forces to better understand burnout and recommend solutions, but progress has been slow,” Dr. Brilakis said. “Barriers include financial constraints, understaffing, lack of understanding of the root causes of burnout in each practice, and perhaps underappreciation of the consequences of burnout.”

The study was published online in JACC: Cardiovascular Interventions.
 

Too much paperwork

The investigators conducted an international, online survey of IC attending physicians and fellows to assess their psychological well-being. The 78 survey questions prepared by the coauthors were shown to perform similarly to the validated Maslach Burnout Inventory.

A total of 1,159 attendings and 192 fellows completed the survey, representing 12% of U.S. IC attendings and 19% of U.S. IC fellows.

Half of attending physicians were from the United States, followed by the European Union (16%). Overall, 37% were from academic institutions; the median age was 41-45 years; 91% were men; and mean clinical work hours per week were 63.

Most (86%) had a partner with whom they lived. Yet most (84%) also felt lonely; 41% considered leaving their jobs during the past year; and 32% said they were currently considering leaving.  

Compared with the previous year, 12% had increased enthusiasm and 44% had decreased enthusiasm toward work. One-third (33%) felt overwhelmed and 20% doubted the significance of their work three or more times a week.

As noted, most (78%) felt they were “working too hard,” were emotionally exhausted (64%), and frustrated by work (58%). Almost one-third (30%) considered themselves physically unhealthy.

Unhappiness was highest (33%) among 51- to 60-year-olds, followed by 31- to 40-year-olds (31%); it was lowest (21%) among those over age 60.

Unhappiness was similar between men and women (27% vs. 30%) and was highest in North America (30%) and lower in Asia (26%).

Most (69%) respondents said that burnout impacted their life, with very little difference between men and women (68% vs. 73%).

Two-thirds (67%) said they had somebody they could share their mental health concerns with, yet only 37% reported having access to mental health support if needed through their hospital/practice.

For fellows, the median age was 31-35 years; 88% were men; 42% were from the United States and 22% from the European Union. Two-thirds were from academic institutions (67%) and the mean clinical work hours were 67 per week.

Two-thirds (67%) lived with a partner; half (48%) felt lonely, 29% considered leaving their jobs in the past year, and 15% were currently considering leaving.

Compared with the previous year, 27% had increased enthusiasm, and 32% had decreased enthusiasm toward work. More than one-quarter (29%) felt overwhelmed and 26% doubted the significance of their work three or more times per week.

Attendings rated excessive paperwork requirements, bureaucratic tasks, challenges in equipment acquisition, and excessive government regulations higher (in contributing to burnout) compared with fellows.

Non-U.S. attendings reported insufficient income and challenges with equipment acquisition as significant contributors to their burnout more than did their United States counterparts.

Fellows rated insufficient income as the most significant contributor to burnout.

Their main coping mechanisms were talking with family/friends (at 6.8 rated on a scale of 0-10), watching movies (6.4), and listening/playing music (6.0).

Attendings were more likely to use exercise as a coping skill, and fellows were more likely to cope by watching movies/series, sleeping, and eating junk food.

Asked what hospitals and practices can do to reduce burnout and improve well-being, attendings suggested removing rules/regulations that do not contribute to patient care, such as reforming prior authorization (mean rating, 8.1), better administrative support (8.0), and professional growth opportunities (7.9).

Non-U.S. attendings more often requested growth opportunities, increased compensation, availability of better hospital food, better hospital infrastructure, streamlined access to equipment, better on-call rooms, and access to mental health professionals to improve their well-being.

Overall, fellows were more likely than were attendings to request professional growth opportunities and were more likely to ask for availability of better food in the hospital, and better on-call rooms.
 

 

 

Reforms needed

Laxmi Mehta, MD, chief well-being leader, faculty director of the Gabbe Health and Well-Being Program, professor of medicine at The Ohio State University Wexner Medical Center in Columbus, and spokesperson for the American Heart Association, noted, “The burnout rates are much higher than our previously reported American College of Cardiology data, which found burnout rates at about 27%; however, that survey was conducted prepandemic,” she said. Dr. Mehta was the lead author of that 2019 report.

She said in an interview that she would have liked to see more breakdowns by gender, and whether there was an association between burnout and the number of procedures performed.

“Nevertheless,” she said, “the rates are very high for burnout, stress, and dissatisfaction, as well as mental health issues. Almost one half of the IC attendings considered leaving their job, which is also seen in other surveys, and is concerning given the projected shortages in the workforce.”

Changes need to be made in the profession of medicine as a whole, she said, though that is unlikely to happen any time soon. “Optimizing workflows and improving the work culture requires not only time, but also collaboration between administration and clinicians, along with an intent and strategic plan focused on well-being of the organization.”

With regard to prior authorization, she said, “medical organizations are advocating for reform at the state and national level. If meaningful reforms can occur, that can reduce some of the bureaucracy. However, there is much more [bureaucracy] in medicine.”

With respect to mental health, she added, “there is a lot that needs to be done to reduce the stigma of seeking help. Many physicians don’t seek help due to the shame, lack of time, and potential impact it can have on hospital credentialing and state medical licensing. Medical organizations and individuals are advocating for reforms in this space, as well, to normalize mental health.”

The Minneapolis Heart Institute Foundation’s Science Center for Coronary Artery Disease helped support this research project. Dr. Brilakis, study coauthors, and Dr. Mehta report no relevant financial relationships.

ChatGPT in medicine: The good, the bad, and the unknown

Article Type
Changed
Tue, 06/20/2023 - 10:09

ChatGPT and other artificial intelligence (AI)–driven natural language processing platforms are here to stay, so like them or not, physicians might as well figure out how to optimize their role in medicine and health care. That’s the takeaway from a three-expert panel session about the technology held at the annual Digestive Disease Week® (DDW).

The chatbot can help doctors to a certain extent by suggesting differential diagnoses, assisting with clinical note-taking, and producing rapid and easy-to-understand patient communication and educational materials, they noted. However, it can also make mistakes. And, unlike a medical trainee who might give a clinical answer and express some doubt, ChatGPT (Open AI/Microsoft) clearly states its findings as fact, even when it’s wrong.

Known as “hallucinating,” this problem of AI inaccuracy was displayed at the packed DDW session.

When asked when Leonardo da Vinci painted the Mona Lisa, for example, ChatGPT replied 1815. That’s off by about 300 years; the masterpiece was created sometime between 1503 and 1519. Asked for a fact about George Washington, ChatGPT said he invented the cotton gin. Also not true. (Eli Whitney patented the cotton gin.)

In an example more suited for gastroenterologists at DDW, ChatGPT correctly stated that Barrett esophagus can lead to adenocarcinoma of the esophagus in some cases. However, the technology also said that the condition could lead to prostate cancer.

So, if someone asked ChatGPT for a list of possible risks for Barrett’s esophagus, it would include prostate cancer. A person without medical knowledge “could take it at face value that it causes prostate cancer,” said panelist Sravanthi Parasa, MD, a gastroenterologist at Swedish Medical Center, Seattle.

“That is a lot of misinformation that is going to come our way,” she added at the session, which was sponsored by the American Society for Gastrointestinal Endoscopy.

The potential for inaccuracy is a downside to ChatGPT, agreed panelist Prateek Sharma, MD, a gastroenterologist at the University of Kansas Medical Center in Kansas City, Kansas.

“There is no quality control. You have to double check its answers,” said Dr. Sharma, who is president-elect of ASGE.

ChatGPT is not going to replace physicians in general or gastroenterologists doing endoscopies, said Ian Gralnek, MD, chief of the Institute of Gastroenterology and Hepatology at Emek Medical Center in Afula, Israel.

Even though the tool could play a role in medicine, “we need to be very careful as a society going forward ... and see where things are going,” Dr. Gralnek said.
 

How you ask makes a difference

Future iterations of ChatGPT are likely to produce fewer hallucinations, the experts said. In the meantime, users can lower the risk by paying attention to how they’re wording their queries, a practice known as “prompt engineering.”

It’s best to ask a question that has a firm answer to it. If you ask a vague question, you’ll likely get a vague answer, Dr. Sharma said.

ChatGPT is a large language model (LLM). GPT stands for “generative pretrained transformer” – specialized algorithms that find long-range patterns in sequences of data. LLMs can predict the next word in a sentence.

“That’s why this is also called generative AI,” Dr. Sharma said. “For example, if you put in ‘Where are we?’, it will predict for you that perhaps the next word is ‘going?’ ”

The current public version is ChatGPT 3.5, which was trained on open-source online information up until early 2022. It can gather information from open-access scientific journals and medical society guidelines, as well as from Twitter, Reddit, and other social media. It does not have access to private information, like electronic health records.

The use of ChatGPT has exploded in the past 6 months, Dr. Sharma said.

“ChatGPT has been the most-searched website or platform ever in history since it was launched in December of 2022,” he said.
 

 

 

What’s in it for doctors?

Although not specifically trained for health care–related tasks, the panelists noted that ChatGPT does have potential as a virtual medical assistant, chatbot, clinical decision-support tool, source of medical education, natural language processor for documentation, or medical note-taker.

ChatGPT can help physicians write a letter of support to a patient who, for example, was just diagnosed with stage IV colon cancer. It can do that in only 15 seconds, whereas it would take us much longer, Dr. Sharma said.

ChatGPT is the “next frontier” for generating patient education materials, Dr. Parasa said. It can help time-constrained health care providers, as long as the information is accurate.

ChatGPT 4.0, now available by subscription, can do “almost real-time note-taking during patient encounters,” she added.

Another reason to be familiar with the technology: “Many of your patients are using it, even if you don’t know about it,” Dr. Sharma said.
 

Questions abound

A conference attendee asked the panel what to do when a patient comes in with ChatGPT medical advice that does not align with official guidelines.

Dr. Gralnek said that he would explain to patients that medical information based on guidelines are not “black and white.” The panel likened it to how patients come to an appointment now armed with information from the Internet, which is not always correct, that must then be countered by doctors. The same would likely happen with ChatGPT.

Another attendee asked whether ChatGPT eventually will work in accordance with electronic health record systems.

“Open AI and Microsoft are already working with Epic,” Dr. Parasa said.

A question arose about the reading level of information provided by ChatGPT. Dr. Parasa noted that it’s not standard. However, a person can prompt ChatGPT to provide an answer either at an eighth-grade reading level or for a well-trained physician.

Dr. Sharma offered a final warning: The technology learns over time.

“It knows what your habits are. It will learn what you’re doing,” Dr. Sharma said. “Everything else on your browsers that are open, it’s learning from that also. So be careful what websites you visit before you go to ChatGPT.”

Dr. Sharma is a stock shareholder in Microsoft. Dr. Parasa and Dr. Gralneck reported no relevant financial relationships.

ChatGPT and other artificial intelligence (AI)–driven natural language processing platforms are here to stay, so like them or not, physicians might as well figure out how to optimize their role in medicine and health care. That’s the takeaway from a three-expert panel session about the technology held at the annual Digestive Disease Week® (DDW).

The chatbot can help doctors to a certain extent by suggesting differential diagnoses, assisting with clinical note-taking, and producing rapid and easy-to-understand patient communication and educational materials, they noted. However, it can also make mistakes.

Etrasimod looks safe for ulcerative colitis out to 2.5 years

Article Type
Changed
Tue, 06/20/2023 - 10:10

A new agent under consideration for approval by the Food and Drug Administration to treat moderately to severely active ulcerative colitis (UC) has an “acceptable” safety profile, new evidence reveals.

Etrasimod (Arena Pharma/Pfizer) is an oral sphingosine-1-phosphate (S1P) receptor that binds with high affinity to receptors 1, 4, and 5. If approved by the FDA, etrasimod could become the second agent in the S1P class approved for ulcerative colitis in the United States. The other agent, ozanimod (Zeposia), received FDA approval for treating moderately to severely active UC in May 2021.

The updated safety profile of etrasimod, presented at the annual Digestive Disease Week® (DDW), is based on data from multiple clinical trials, including OASIS phase 2 and the ELEVATE phase 3, placebo-controlled trials, as well as an ongoing, open-label extension study.

“Etrasimod was well tolerated in patients with moderately to severely active UC and had an acceptable safety profile that did not appear to change with longer-term treatment up to 2.5 years,” said OASIS lead author Séverine Vermeire, MD, PhD, an expert on translational research in gastrointestinal disorders and professor of medicine at KU Leuven (Belgium), while presenting the findings at DDW.

Dr. Vermeire noted that data show an elevated risk for atrioventricular (AV) block or bradycardia in a minority of people treated with the agent during this time period. However, most of the heart-related risk was during induction, and the risks could be minimized by ordering an electrocardiogram before prescribing, she said.
 

Cumulative safety data

Researchers separated the trial participants into two cohorts. The all-UC cohort consisted of 956 patients who took at least one dose of etrasimod. The placebo-controlled cohort consisted of 629 patients taking etrasimod and 314 patients who took a placebo. Some patients participated in more than one study, the researchers noted.

In both cohorts, mean duration of disease was about 7 years, about 42% of all participants were female, and mean age was about 41 years.

The investigators looked at the frequency of adverse events and exposure-adjusted incidence rates from the OASIS phase 2 and the ELEVATE phase 3 placebo-controlled trials, as well as an ongoing, open-label extension study. They also assessed safety in placebo and 1 mg or 2 mg etrasimod in the phase 2 NCT02447302 or two phase 3 trials, NCT03945188 and NCT03996369, reported up until Jan. 31, 2022.

There were 770 patient-years of etrasimod exposure in the all-UC cohort, while exposure in the placebo-controlled cohort was 288 patient-years in the etrasimod group and 115 patient-years in the placebo group. Mean exposure to etrasimod was 42 weeks in the all-UC cohort. Mean exposure in the placebo-controlled cohort was 24 weeks in the etrasimod group and 19 weeks in the placebo group.

Because of the mechanism of action of etrasimod, Dr. Vermeire and colleagues focused on cardiovascular events, macular edema, severe or opportunistic infections, herpes zoster infections, and malignancies.

Eleven patients (1.8%) treated with etrasimod reported bradycardia or sinus bradycardia in the placebo-controlled research, and 9 of 11 were asymptomatic. No bradycardia was associated with taking a placebo. In the all-UC cohort, bradycardia or sinus bradycardia was reported in 14 patients (1.5%).

“Bradycardia is something you need to tell patients may occur,” Dr. Vermeire said. “Most of the bradycardia occurred on day one or day two, mostly on day one.”

Four people taking etrasimod in the placebo-controlled cohort and 7 people in the all-UC cohort had AV block of the first or second degree. No reports of AV block occurred in the placebo group.

“Other adverse events of special interest, including hypertension and macular edema, were all rare and similar between the treatment arms,” Dr. Vermeire said.

Herpes zoster infections were reported in two patients taking etrasimod and two taking placebo in the placebo-controlled cohort. Seven cases were reported in the all-UC cohort. Dr. Vermeire said she advocates vaccinating patients against herpes zoster soon after UC diagnosis, if possible.

In the placebo-controlled cohort, 11 patients taking etrasimod and two patients taking placebo experienced elevated ALT. This was fewer than 2% of patients. One patient taking etrasimod and one receiving placebo discontinued the study for this reason. In the all-UC cohort, 27 people experienced elevated ALT.

In the placebo-controlled cohort, 13 people treated with etrasimod and two taking placebo developed elevated gamma-glutamyltransferase. This adverse event was reported in 32 patients in the all-UC cohort.

There were no deaths reported in the placebo-controlled cohort of patients. One patient in the all-UC cohort developed a neuroendocrine tumor and died. The person received etrasimod 2 mg daily for about 6 months before the event’s onset. “This was assessed as unlikely related to the study treatment as judged by investigators,” Dr. Vermeire said.

Limitations of the study include a relatively short average duration of exposure to etrasimod.

“As the study continues, we will continue collecting and reporting the safety data,” Dr. Vermeire said.
 

 

 

A well-tolerated therapy

“The important take-home message is that patients tolerated therapy very well,” said session comoderator Jordan E. Axelrad, MD, MPH, when asked to comment.

There were very few adverse events, and of these, they were mostly minor, with patients being able to continue on therapy in large part, added Dr. Axelrad, a gastroenterologist at the Inflammatory Bowel Disease Center at NYU Langone Health, New York.

Physicians will “need to get comfortable” with ordering an ECG to screen patients before prescribing etrasimod, he noted.

“Once we can get past that hurdle [of ordering an ECG], we should be integrating it into our practice,” Dr. Axelrad said.

The study was funded by Arena Pharmaceuticals, which was acquired by Pfizer; Pfizer completed the acquisition in March 2022. Dr. Vermeire reported receiving consulting and speaking fees from Arena Pharmaceuticals and grant and research support from Pfizer. Dr. Axelrad reported no relevant financial relationships.

DDW is sponsored by the American Association for the Study of Liver Diseases, the American Gastroenterological Association, the American Society for Gastrointestinal Endoscopy, and The Society for Surgery of the Alimentary Tract.

They also assessed safety in placebo and 1 mg or 2 mg etrasimod in the phase 2 NCT02447302 or two phase 3 trials, NCT03945188 and NCT03996369, reported up until Jan. 31, 2022.

There were 770 patient-years of etrasimod exposure in the all-UC cohort, while exposure in the placebo-controlled cohort was 288 patient-years in the etrasimod group and 115 patient-years in the placebo group. Mean exposure to etrasimod was 42 weeks in the all-UC cohort. Mean exposure in the placebo-controlled cohort was 24 weeks in the etrasimod group and 19 weeks in the placebo group.

Because of the mechanism of action of etrasimod, Dr. Vermeire and colleagues focused on cardiovascular events, macular edema, severe or opportunistic infections, herpes zoster infections, and malignancies.

Eleven patients (1.8%) treated with etrasimod reported bradycardia or sinus bradycardia in the placebo-controlled research, and 9 of 11 were asymptomatic. No bradycardia was associated with taking a placebo. In the all-UC cohort, bradycardia or sinus bradycardia was reported in 14 patients (1.5%).

“Bradycardia is something you need to tell patients may occur,” Dr. Vermeire said. “Most of the bradycardia occurred on day one or day two, mostly on day one.”

Four people taking etrasimod in the placebo-controlled cohort and 7 people in the all-UC cohort had AV block of the first or second degree. No reports of AV block occurred in the placebo group.

“Other adverse events of special interest, including hypertension and macular edema, were all rare and similar between the treatment arms,” Dr. Vermeire said.

Herpes zoster infections were reported in two patients taking etrasimod and two taking placebo in the placebo-controlled cohort. Seven cases were reported in the all-UC cohort. Dr. Vermeire said she advocates vaccinating patients against herpes zoster soon after UC diagnosis, if possible.

In the placebo-controlled cohort, 11 patients taking etrasimod and two patients taking placebo experienced elevated ALT. This was fewer than 2% of patients. One patient taking etrasimod and one receiving placebo discontinued the study for this reason. In the all-UC cohort, 27 people experienced elevated ALT.

In the placebo-controlled cohort, 13 people treated with etrasimod and two taking placebo developed elevated gamma-glutamyltransferase. This adverse event was reported in 32 patients in the all-UC cohort.

There were no deaths reported in the placebo-controlled cohort of patients. One patient in the all-UC cohort developed a neuroendocrine tumor and died. The person received etrasimod 2 mg daily for about 6 months before the event’s onset. “This was assessed as unlikely related to the study treatment as judged by investigators,” Dr. Vermeire said.

Limitations of the study include a relatively short average duration of exposure to etrasimod.

“As the study continues, we will continue collecting and reporting the safety data,” Dr. Vermeire said.
 

 

 

A well-tolerated therapy

“The important take-home message is that patients tolerated therapy very well,” said session comoderator Jordan E. Axelrad, MD, MPH, when asked to comment.

There were very few adverse events, and of these, they were mostly minor, with patients being able to continue on therapy in large part, added Dr. Axelrad, a gastroenterologist at the Inflammatory Bowel Disease Center at NYU Langone Health, New York.

Physicians will “need to get comfortable” with ordering an ECG to screen patients before prescribing etrasimod, he noted.

“Once we can get past that hurdle [of ordering an ECG], we should be integrating it into our practice,” Dr. Axelrad said.

The study was funded by Arena Pharmaceuticals, which was acquired by Pfizer; Pfizer completed the acquisition in March 2022. Dr. Vermeire reported receiving consulting and speaking fees from Arena Pharmaceuticals and grant and research support from Pfizer. Dr. Axelrad reported no relevant financial relationships.

2023 Update on gynecologic cancer

Article Type
Changed
Wed, 06/21/2023 - 11:03

In 2022, the most significant advances in the treatment of gynecologic cancers were achieved for patients with ovarian cancer. While ovarian cancer continues to carry the worst prognosis of all gynecologic cancers, 5-year relative survival has gradually increased, from 34.4% in 1975 to 52.4% in 2014.1

In this Update, we highlight the recent advances in our understanding of targeted therapy in ovarian cancer. We review SORAYA, a trial that demonstrated that mirvetuximab soravtansine, an antibody-drug conjugate, has promising efficacy in platinum-resistant ovarian cancers that overexpress folate receptor α. We also spotlight progress in the treatment of low-grade serous ovarian cancer, another notoriously chemotherapy-resistant disease, in GOG 281/LOGS, a phase 2 study of the MEK inhibitor trametinib. Finally, we discuss emerging long-term follow-up data on poly(ADP-ribose) polymerase (PARP) inhibitors, which are helping to refine the role of these groundbreaking drugs.

New drug approved for platinum-resistant epithelial ovarian cancer—the first since 2014

Matulonis UA, Lorusso D, Oaknin A, et al. Efficacy and safety of mirvetuximab soravtansine in patients with platinum-resistant ovarian cancer with high folate receptor alpha expression: results from the SORAYA study. J Clin Oncol. 2023;41:2436-2445. doi:10.1200/JCO.22.01900.

While most patients diagnosed with advanced ovarian cancer will respond to platinum-based chemotherapy, those whose disease recurs eventually develop resistance to platinum agents. Treatment options for platinum-resistant ovarian cancer are limited and prognosis is poor. Most regimens have a response rate of only 10%. Since the approval of bevacizumab combined with chemotherapy in 2014, no new agents have been approved by the US Food and Drug Administration (FDA) for use in platinum-resistant ovarian cancer.

 

Efficacy shown with mirvetuximab

Recently, Matulonis and colleagues published results of the SORAYA study, a single-arm,phase 2 trial, that examined the efficacy and safety of mirvetuximab soravtansine-gynx among women with platinum-resistant ovarian cancer.2 Mirvetuximab is an antibody-drug conjugate composed of an antibody directed at the folate receptor α attached to a cytotoxic microtubule inhibitor.

The study included 106 patients with platinum-resistant ovarian cancer whose tumors expressed folate receptor α at a high level—a feature of approximately 50% of patients screened for the study. Twenty-nine patients experienced a partial response and 5 had a complete response, corresponding to a remarkable objective response rate of 32.4%. The median progression-free survival was 4.3 months.

Like other antibody-drug conjugates, ocular toxicities, including blurred vision (41%) and keratopathy (29%), were common. However, toxicity was manageable and rarely led to drug discontinuation.

WHAT THIS EVIDENCE MEANS FOR PRACTICE
The FDA has granted accelerated approval to mirvetuximab soravtansine-gynx for women with platinum-resistant ovarian cancer with high folate receptor α expression who have received 1 to 3 prior systemic treatment regimens.

A novel agent for recurrent low-grade serous ovarian carcinoma

Gershenson DM, Miller A, Brady WE, et al. Trametinib versus standard of care in patients with recurrent low-grade serous ovarian cancer (GOG 281/LOGS): an international, randomised, open-label, multicentre, phase 2/3 trial. Lancet. 2022;399:541-553. doi:10.1016/S0140-6736(21)02175-9.

Low-grade serous carcinoma is a histologic subtype that makes up approximately 5% of all epithelial ovarian cancers.3 Patients with low-grade serous carcinoma are often younger and, because of the indolent nature of the histology, generally have a longer overall survival compared with patients with high-grade serous carcinoma. Unlike high-grade disease, however, low-grade serous carcinoma usually is resistant to chemotherapy, making treatment options limited for patients with advanced and recurrent disease.

 

Trametinib: A potential option

In an international, randomized, open-label trial (GOG 281/LOGS), Gershenson and colleagues investigated the efficacy of trametinib compared with standard-of-care chemotherapy in patients with recurrent low-grade serous ovarian cancer.4 Trametinib, a mitogen-activated protein kinase MEK inhibitor, is a targeted agent that is FDA approved for treatment in BRAF-mutated melanoma, lung, and thyroid cancers.

Patients with recurrent low-grade serous ovarian cancer were randomly assigned to trametinib (n = 130) or 1 of 5 standard-of-care treatment options (n = 130), including both chemotherapy and hormonal treatments. Those assigned to trametinib were significantly less likely to have disease progression (78% vs 89%), with a median progression-free survival of 13 months, compared with7.2 months in controls (hazard ratio [HR], 0.48; 95% confidence interval [CI], 0.36–0.64). Additionally, patients who had a radiographic response to trametinib experienced a longer duration of response compared with those who responded to standard-of-care treatment (13.6 months vs 5.9 months).

While there was no statistically significant difference in overall survival (HR, 0.76; 95% CI, 0.51–1.12), crossover to trametinib from the standard-of-care group was allowed and occurred among 68% of patients, which limits the study’s ability to measure differences in overall survival.

Trametinib was well tolerated by patients, but skin rash and anemia followed by hypertension were the most common adverse effects. In the standard-of-care group, the most common toxicities were abdominal pain, nausea, and anemia. A slightly higher proportion of patients in the trametinib group discontinued the drug due to toxicity compared with the standard-of-care group (36% vs 30%), but the there was no difference between the 2 groups in scores on quality-of-life assessments.

WHAT THIS EVIDENCE MEANS FOR PRACTICE
Although trametinib is not yet FDA approved for the treatment of ovarian cancer, the National Comprehensive Cancer Network has added trametinib as a treatment option for recurrent low-grade serous ovarian carcinoma, given the significant improvement in progression-free survival compared with standard-of-care treatment.

PARP inhibitors benefit many women with ovarian cancer, but they may hurt others

Monk BJ, Parkinson C, Lim MC, et al. A randomized, phase III trial to evaluate rucaparib monotherapy as maintenance treatment in patients with newly diagnosed ovarian cancer (ATHENA-MONO/GOG-3020/ENGOT-ov45). J Clin Oncol. 2022;40:3952-3964. doi:10.1200/JCO.22.01003.

Poly(ADP-ribose) polymerase (PARP) inhibitors are a class of oral anticancer agents that target DNA repair. Since the initial FDA approval in 2014 of olaparib for the treatment of patients with recurrent BRCA-mutated ovarian cancer, PARP inhibitors have been approved for maintenance in both the frontline setting and after platinum-sensitive recurrence, and as single-agenttreatment for ovarian cancer with BRCA mutations or evidence of homologous repair deficiency (HRD), a BRCA-like molecular phenotype.5 The expanding role for PARP inhibitors in ovarian cancer seemed inexorable.

 

Restricted prescribing advised

In 2022, we learned that in certain settings, PARP inhibitors may be the wrong choice. Several “Dear Health Care Provider” letters were issued by AstraZeneca, Clovis, and GSK to advise physicians to restrict the prescribing of olaparib, rucaparib, and niraparib.6,7

AstraZeneca and Clovis issued letters spurred by the final analysis of ARIEL4 and SOLO3 studies, 2 randomized trials that investigated, respectively, rucaparib and olaparib monotherapy compared with chemotherapy in recurrent ovarian cancer.8,9 In both cases patients randomized to PARP inhibitors may have experienced an overall survival decrement compared with those who received chemotherapy.

At the FDA’s request, Clovis has withdrawn rucaparib as a treatment for patients with recurrent BRCA-mutant ovarian cancer who had received 2 or more lines of chemotherapy, and AstraZeneca withdrew olaparib monotherapy in germline BRCA-mutant patients with recurrent ovarian cancer. Shortly after these withdrawals, GSK also withdrew its indication for niraparib as a treatment for women with HRD, platinum-sensitive ovarian cancer who have received 3 or more prior chemotherapies. Furthermore, based on the final overall survival analysis of the NOVA study, GSK also restricted its indication for niraparib maintenance for recurrent ovarian cancer to patients with germline BRCA mutations, due to evidence of an overall survival detriment in this setting.10

Positive study results

Fortunately, 2022 was not all bad news for PARP inhibitors in ovarian cancer. In June 2022, the ATHENA-MONO trial, a phase 3 double-blind randomized controlled trial, demonstrated that rucaparib maintenance in patients with newly diagnosed epithelial ovarian cancer was associated with a significantly longer progression-free survival compared with placebo.11 The effect was most pronounced in the BRCA-mutant/HRD population, with a median progression-free survival of 28.7 months in the rucaparib group compared with 11.3 months in the placebo group (HR, 0.47; 95% CI, 0.31–0.72). Thus, rucaparib was added to the list of PARP inhibitors approved for upfront maintenance therapy in epithelial ovarian cancer.

Similarly, the long-term overall survival analysis from the upfront trials SOLO-1 and PAOLA-1 showed an overall survival advantage of PARP inhibitor, compared with placebo, maintenance in patients with BRCA mutations or HRD tumors.12,13

WHAT THIS EVIDENCE MEANS FOR PRACTICE
PARP inhibitor maintenance therapy after upfront chemotherapy in women with BRCA-mutant and HRD epithelial ovarian cancer has been game changing in ovarian cancer. However, PARP inhibitors have a more limited role than previously thought for patients with recurrent ovarian cancer.

A novel agent for recurrent low-grade serous ovarian carcinoma

In this Update, we highlight the recent advances in our understanding of targeted therapy in ovarian cancer. We review SORAYA, a trial that demonstrated that mirvetuximab soravtansine, an antibody-drug conjugate, has promising efficacy in platinum-resistant ovarian cancers that overexpress folate receptor α. We also spotlight progress in the treatment of low-grade serous ovarian cancer, another notoriously chemotherapy-resistant disease, in GOG 281/LOGS, a phase 2 study of the MEK inhibitor trametinib. Finally, we discuss emerging long-term follow-up data on poly(ADP-ribose) polymerase (PARP) inhibitors, which are helping to refine the role of these groundbreaking drugs.

New drug approved for platinum-resistant epithelial ovarian cancer—the first since 2014

Matulonis UA, Lorusso D, Oaknin A, et al. Efficacy and safety of mirvetuximab soravtansine in patients with platinum-resistant ovarian cancer with high folate receptor alpha expression: results from the SORAYA study. J Clin Oncol. 2023;41:2436-2445. doi:10.1200/JCO.22.01900.

While most patients diagnosed with advanced ovarian cancer will respond to platinum-based chemotherapy, those whose disease recurs eventually develop resistance to platinum agents. Treatment options for platinum-resistant ovarian cancer are limited and prognosis is poor. Most regimens have a response rate of only 10%. Since the approval of bevacizumab combined with chemotherapy in 2014, no new agents have been approved by the US Food and Drug Administration (FDA) for use in platinum-resistant ovarian cancer.

 

Efficacy shown with mirvetuximab

Recently, Matulonis and colleagues published results of the SORAYA study, a single-arm,phase 2 trial, that examined the efficacy and safety of mirvetuximab soravtansine-gynx among women with platinum-resistant ovarian cancer.2 Mirvetuximab is an antibody-drug conjugate composed of an antibody directed at the folate receptor α attached to a cytotoxic microtubule inhibitor.

The study included 106 patients with platinum-resistant ovarian cancer whose tumors expressed folate receptor α at a high level—a feature of approximately 50% of patients screened for the study. Twenty-nine patients experienced a partial response and 5 had a complete response, corresponding to a remarkable objective response rate of 32.4%. The median progression-free survival was 4.3 months.

Like other antibody-drug conjugates, ocular toxicities, including blurred vision (41%) and keratopathy (29%), were common. However, toxicity was manageable and rarely led to drug discontinuation.

WHAT THIS EVIDENCE MEANS FOR PRACTICE
The FDA has granted accelerated approval to mirvetuximab soravtansine-gynx for women with platinum-resistant ovarian cancer with high folate receptor α expression who have received 1 to 3 prior systemic treatment regimens.

A novel agent for recurrent low-grade serous ovarian carcinoma

Gershenson DM, Miller A, Brady WE, et al. Trametinib versus standard of care in patients with recurrent low-grade serous ovarian cancer (GOG 281/LOGS): an international, randomised, open-label, multicentre, phase 2/3 trial. Lancet. 2022;399:541-553. doi:10.1016/S0140-6736(21)02175-9.

Low-grade serous carcinoma is a histologic subtype that makes up approximately 5% of all epithelial ovarian cancers.3 Patients with low-grade serous carcinoma are often younger and, because of the indolent nature of the histology, generally have a longer overall survival compared with patients with high-grade serous carcinoma. Unlike high-grade disease, however, low-grade serous carcinoma usually is resistant to chemotherapy, making treatment options limited for patients with advanced and recurrent disease.

 

Trametinib: A potential option

In an international, randomized, open-label trial (GOG 281/LOGS), Gershenson and colleagues investigated the efficacy of trametinib compared with standard-of-care chemotherapy in patients with recurrent low-grade serous ovarian cancer.4 Trametinib, a mitogen-activated protein kinase MEK inhibitor, is a targeted agent that is FDA approved for treatment in BRAF-mutated melanoma, lung, and thyroid cancers.

Patients with recurrent low-grade serous ovarian cancer were randomly assigned to trametinib (n = 130) or 1 of 5 standard-of-care treatment options (n = 130), including both chemotherapy and hormonal treatments. Those assigned to trametinib were significantly less likely to have disease progression (78% vs 89%), with a median progression-free survival of 13 months, compared with7.2 months in controls (hazard ratio [HR], 0.48; 95% confidence interval [CI], 0.36–0.64). Additionally, patients who had a radiographic response to trametinib experienced a longer duration of response compared with those who responded to standard-of-care treatment (13.6 months vs 5.9 months).

While there was no statistically significant difference in overall survival (HR, 0.76; 95% CI, 0.51–1.12), crossover to trametinib from the standard-of-care group was allowed and occurred among 68% of patients, which limits the study’s ability to measure differences in overall survival.

Trametinib was well tolerated by patients, but skin rash and anemia followed by hypertension were the most common adverse effects. In the standard-of-care group, the most common toxicities were abdominal pain, nausea, and anemia. A slightly higher proportion of patients in the trametinib group discontinued the drug due to toxicity compared with the standard-of-care group (36% vs 30%), but the there was no difference between the 2 groups in scores on quality-of-life assessments.

WHAT THIS EVIDENCE MEANS FOR PRACTICE
Although trametinib is not yet FDA approved for the treatment of ovarian cancer, the National Comprehensive Cancer Network has added trametinib as a treatment option for recurrent low-grade serous ovarian carcinoma, given the significant improvement in progression-free survival compared with standard-of-care treatment.

PARP inhibitors benefit many women with ovarian cancer, but they may hurt others

Monk BJ, Parkinson C, Lim MC, et al. A randomized, phase III trial to evaluate rucaparib monotherapy as maintenance treatment in patients with newly diagnosed ovarian cancer (ATHENA-MONO/GOG-3020/ENGOT-ov45). J Clin Oncol. 2022;40:3952-3964. doi:10.1200/JCO.22.01003.

Poly(ADP-ribose) polymerase (PARP) inhibitors are a class of oral anticancer agents that target DNA repair. Since the initial FDA approval in 2014 of olaparib for the treatment of patients with recurrent BRCA-mutated ovarian cancer, PARP inhibitors have been approved for maintenance in both the frontline setting and after platinum-sensitive recurrence, and as single-agenttreatment for ovarian cancer with BRCA mutations or evidence of homologous repair deficiency (HRD), a BRCA-like molecular phenotype.5 The expanding role for PARP inhibitors in ovarian cancer seemed inexorable.

 

Restricted prescribing advised

In 2022, we learned that in certain settings, PARP inhibitors may be the wrong choice. Several “Dear Health Care Provider” letters were issued by AstraZeneca, Clovis, and GSK to advise physicians to restrict the prescribing of olaparib, rucaparib, and niraparib.6,7

AstraZeneca and Clovis issued letters spurred by the final analysis of ARIEL4 and SOLO3 studies, 2 randomized trials that investigated, respectively, rucaparib and olaparib monotherapy compared with chemotherapy in recurrent ovarian cancer.8,9 In both cases patients randomized to PARP inhibitors may have experienced an overall survival decrement compared with those who received chemotherapy.

At the FDA’s request, Clovis has withdrawn rucaparib as a treatment for patients with recurrent BRCA-mutant ovarian cancer who had received 2 or more lines of chemotherapy, and AstraZeneca withdrew olaparib monotherapy in germline BRCA-mutant patients with recurrent ovarian cancer. Shortly after these withdrawals, GSK also withdrew its indication for niraparib as a treatment for women with HRD, platinum-sensitive ovarian cancer who have received 3 or more prior chemotherapies. Furthermore, based on the final overall survival analysis of the NOVA study, GSK also restricted its indication for niraparib maintenance for recurrent ovarian cancer to patients with germline BRCA mutations, due to evidence of an overall survival detriment in this setting.10

Positive study results

Fortunately, 2022 was not all bad news for PARP inhibitors in ovarian cancer. In June 2022, the ATHENA-MONO trial, a phase 3 double-blind randomized controlled trial, demonstrated that rucaparib maintenance in patients with newly diagnosed epithelial ovarian cancer was associated with a significantly longer progression-free survival compared with placebo.11 The effect was most pronounced in the BRCA-mutant/HRD population, with a median progression-free survival of 28.7 months in the rucaparib group compared with 11.3 months in the placebo group (HR, 0.47; 95% CI, 0.31–0.72). Thus, rucaparib was added to the list of PARP inhibitors approved for upfront maintenance therapy in epithelial ovarian cancer.

Similarly, the long-term overall survival analysis from the upfront trials SOLO-1 and PAOLA-1 showed an overall survival advantage of PARP inhibitor, compared with placebo, maintenance in patients with BRCA mutations or HRD tumors.12,13

WHAT THIS EVIDENCE MEANS FOR PRACTICE
PARP inhibitor maintenance therapy after upfront chemotherapy in women with BRCA-mutant and HRD epithelial ovarian cancer has been game changing in ovarian cancer. However, PARP inhibitors have a more limited role than previously thought for patients with recurrent ovarian cancer.

Combo treatment eases nausea and vomiting of pregnancy

A multicenter randomized controlled trial has provided more evidence that acupuncture and doxylamine-pyridoxine (Diclegis/Diclectin) are modestly effective for the nausea and vomiting of pregnancy (NVP). While the benefit of either agent was clinically small for moderate to severe symptoms, the combination showed numerically larger and potentially more meaningful benefit, according to a team led by Xiao-Ke Wu, MD, PhD, of the department of obstetrics and gynecology at First Affiliated Hospital, Heilongjiang University of Chinese Medicine, and Heilongjiang Provincial Hospital in Harbin, China.

Dr. Xiao-Ke Wu

The treatments found small reductions in symptoms of less than one point to 1.6 points on an emesis scale. Nevertheless, Dr. Wu’s group wrote online June 19 in Annals of Internal Medicine that the finding “is especially significant because there is a pressing need to establish a pregnancy-safe treatment regimen and an integrative guideline for managing severe NVP.”

NVP affects as many as 85% of pregnant women, 80%-90% of whom have only mild symptoms, the authors noted. However, severe NVP and hyperemesis gravidarum, or HG, develop in about 10%. “Unfortunately, as many as 10% of wanted pregnancies with severe NVP or HG are terminated because of intolerable and untreatable symptoms and complications,” Dr. Wu told this news organization. And antiemetics may be underprescribed by general practitioners because of concerns about potential teratogenic effects, he said.

“Our findings suggest that either acupuncture or doxylamine-pyridoxine alone is a suitable for treating moderate to severe NVP, and a combination of both can be used to treat severe NVP and HG,” Dr. Wu said.

Commenting on the study but not involved in it, Catherine S. Stika, MD, a clinical professor of ob.gyn. at Northwestern University in Chicago, said the results suggest these two therapies are more suited to mild than severe symptoms. “But an RCT is important to do in order to support the use of these therapies since they’re not as widely accepted as they ought to be,” she said in an interview.

Dr. Catherine S. Stika


According to Dr. Stika, many pregnant women are reluctant to take drugs at all or participate in drug studies, “so the combination of nonpharmaceutical/pharmaceutical treatment might be a bit more appealing.” She noted that some women have such severe nausea they are literally starving and so weak they are bedridden or even hospitalized.

Both treatments have been recommended for some time, and the American College of Obstetricians and Gynecologists’ 2018 practice bulletin recommends acupuncture for mild nausea.

Design

The randomized, double-blind, placebo-controled 2x2 factorial trial was conducted at 13 tertiary-care hospitals in mainland China from June 2020 to February 2022. The researchers recruited 352 women in early pregnancy with moderate to severe NVP. The mean age of participants was about 29 years and the mean gestational age was about 9 weeks.

Participants were randomized into four 14-day treatment groups: active acupuncture for 30 minutes a day plus the antihistamine-vitamin B6 agent doxylamine-pyridoxine; sham acupuncture for 30 minutes daily plus doxylamine-pyridoxine; active acupuncture plus placebo; and sham acupuncture plus placebo.

The primary outcome was the reduction in Pregnancy-Unique Quantification of Emesis (PUQE) score at day 15 relative to baseline with a score of less than 6 indicating mild NVP, 6-12 indicating moderate NVP, and 13 or higher indicating severe NVP. Secondary outcomes ranged from quality of life and adverse events to maternal and perinatal complications. Acupuncture and combined treatment yielded larger though still small reductions in PUQE score, compared with control treatments. The mean differences were as follows: acupuncture, –.07; 95% confidence interval, 1.3-0.1); doxylamine-pyridoxine, –1.0: 95% CI, 1.6-0.4); combination of both, –1.6; 95% CI, 2.2-0.9). No significant interaction was detected between the interventions (P = .69).Compared with placebo treatments, pharmaceutical therapy resulted in more somnolence, while active acupuncture led to more frequent dyspnea, bruising, itching, and pain. A higher risk of babies born small for gestational age was observed in mothers who took doxylamine-pyridoxine versus placebo: odds ratio, 3.8; 95% CI, 1-14.1). Neither the placebo effects of the sham interventions nor the natural regression of symptoms experienced by many women were evaluated.
 

 

 

Suited to milder symptoms?

Dr. Stika called the study well-designed and well-written but cited several limitations, including the small cohort, the minor symptom improvement, and the lack of a comparator group receiving neither sham nor active treatment.

“Compared with sham combination treatments, the active combination arm was only about a point and a half better,” she said. “And would some women have got better over the 2 weeks anyway with no intervention at all? A large percentage of women with NVP do improve on their own.”

And in terms of acceptability to U.S. women, she cautioned, “The study cohort was entirely Chinese, and this is a population that already accepts acupuncture treatment.”

Countered Dr. Wu, “Medical care provided by licensed acupuncturists is approved in many countries. Certainly, it is ready to be prescribed by physicians when a pregnant patient is seeking NVP treatment.”

Dr. Stika stressed that these therapies are suited to milder NV, and would “barely take edge off severe symptoms,” for which a patient might have to “go up to a big gun like the antiemetic Zofran” (ondansetron). She is currently involved in a National Institutes of Health–funded clinical trial of the antidepressant mirtazapine (Remeron) for NVP.

Matthew Carroll, MD, a professor of obstetrics and gynecology at Baylor College of Medicine and Texas Children’s Hospital in Houston, noted that doxylamine-pyridoxine is already an effective treatment for NVP, but in his experience it is often "not enough" to help patients deal with symptoms.

"Many patients are hesitant to take additional medications," he said. "If acupuncture can be safely done in pregnancy, then it seems a reasonable option as an adjuvant treatment for NVP. I think there is a cohort of pregnant people in the US who would be excited to try a complementary and nonpharmaceutical treatment option. Unfortunately, complementary therapies are rarely evaluated at a systems level for safety and so they are hard to recommend for obstetricians in the US," he added.

Dr. Carroll, who was not involved in the study. noted that "studies like this can help us counsel patients who may be seeking these treatments even if not approved or recommended by ACOG."

This study was funded by the National Key R&D Program of China and the Project of Heilongjiang Province “TouYan” Innovation Team. Support also came from the National Clinical Research Base of Chinese Medicine, the Heilongjiang Provincial Clinical Research Centre for Ovary Diseases, and the 2023 Capability Improvement Project for Evidence-based Assessment of Traditional Chinese Medicine.

Study coauthor Ben Willem J. Mol, MD, PhD, reported consulting fees from ObsEva and Merck and travel fees from Merck.

Dr. Stika and Dr. Carroll had no competing interests to disclose.

Countered Dr. Wu, “Medical care provided by licensed acupuncturists is approved in many countries. Certainly, it is ready to be prescribed by physicians when a pregnant patient is seeking NVP treatment.”

Dr. Stika stressed that these therapies are suited to milder NV, and would “barely take edge off severe symptoms,” for which a patient might have to “go up to a big gun like the antiemetic Zofran” (ondansetron). She is currently involved in a National Institutes of Health–funded clinical trial of the antidepressant mirtazapine (Remeron) for NVP.

Matthew Carroll, MD, a professor of obstetrics and gynecology at Baylor College of Medicine and Texas Children’s Hospital in Houston, noted that doxylamine-pyridoxine is already an effective treatment for NVP, but in his experience it is often "not enough" to help patients deal with symptoms.

"Many patients are hesitant to take additional medications," he said. "If acupuncture can be safely done in pregnancy, then it seems a reasonable option as an adjuvant treatment for NVP. I think there is a cohort of pregnant people in the US who would be excited to try a complementary and nonpharmaceutical treatment option. Unfortunately, complementary therapies are rarely evaluated at a systems level for safety and so they are hard to recommend for obstetricians in the US," he added.

Dr. Carroll, who was not involved in the study. noted that "studies like this can help us counsel patients who may be seeking these treatments even if not approved or recommended by ACOG."

This study was funded by the National Key R&D Program of China and the Project of Heilongjiang Province “TouYan” Innovation Team. Support also came from the National Clinical Research Base of Chinese Medicine, the Heilongjiang Provincial Clinical Research Centre for Ovary Diseases, and the 2023 Capability Improvement Project for Evidence-based Assessment of Traditional Chinese Medicine.

A multicenter randomized controlled trial has provided more evidence that acupuncture and doxylamine-pyridoxine (Diclegis/Diclectin) are modestly effective for the nausea and vomiting of pregnancy (NVP). While the benefit of either agent was clinically small for moderate to severe symptoms, the combination showed numerically larger and potentially more meaningful benefit, according to a team led by Xiao-Ke Wu, MD, PhD, of the department of obstetrics and gynecology at First Affiliated Hospital, Heilongjiang University of Chinese Medicine, and Heilongjiang Provincial Hospital in Harbin, China.

The treatments found small reductions in symptoms of less than one point to 1.6 points on an emesis scale. Nevertheless, Dr. Wu’s group wrote online June 19 in Annals of Internal Medicine that the finding “is especially significant because there is a pressing need to establish a pregnancy-safe treatment regimen and an integrative guideline for managing severe NVP.”

NVP affects as many as 85% of pregnant women, 80%-90% of whom have only mild symptoms, the authors noted. However, severe NVP and hyperemesis gravidarum, or HG, develop in about 10%. “Unfortunately, as many as 10% of wanted pregnancies with severe NVP or HG are terminated because of intolerable and untreatable symptoms and complications,” Dr. Wu told this news organization. And antiemetics may be underprescribed by general practitioners because of concerns about potential teratogenic effects, he said.

“Our findings suggest that either acupuncture or doxylamine-pyridoxine alone is a suitable for treating moderate to severe NVP, and a combination of both can be used to treat severe NVP and HG,” Dr. Wu said.

Commenting on the study but not involved in it, Catherine S. Stika, MD, a clinical professor of ob.gyn. at Northwestern University in Chicago, said the results suggest these two therapies are more suited to mild than severe symptoms. “But an RCT is important to do in order to support the use of these therapies since they’re not as widely accepted as they ought to be,” she said in an interview.

According to Dr. Stika, many pregnant women are reluctant to take drugs at all or participate in drug studies, “so the combination of nonpharmaceutical/pharmaceutical treatment might be a bit more appealing.” She noted that some women have such severe nausea they are literally starving and so weak they are bedridden or even hospitalized.

Both treatments have been recommended for some time, and the American College of Obstetricians and Gynecologists’ 2018 practice bulletin recommends acupuncture for mild nausea.

Design

The randomized, double-blind, placebo-controled 2x2 factorial trial was conducted at 13 tertiary-care hospitals in mainland China from June 2020 to February 2022. The researchers recruited 352 women in early pregnancy with moderate to severe NVP. The mean age of participants was about 29 years and the mean gestational age was about 9 weeks.

Participants were randomized into four 14-day treatment groups: active acupuncture for 30 minutes a day plus the antihistamine-vitamin B6 agent doxylamine-pyridoxine; sham acupuncture for 30 minutes daily plus doxylamine-pyridoxine; active acupuncture plus placebo; and sham acupuncture plus placebo.

The primary outcome was the reduction in Pregnancy-Unique Quantification of Emesis (PUQE) score at day 15 relative to baseline with a score of less than 6 indicating mild NVP, 6-12 indicating moderate NVP, and 13 or higher indicating severe NVP. Secondary outcomes ranged from quality of life and adverse events to maternal and perinatal complications. Acupuncture and combined treatment yielded larger though still small reductions in PUQE score, compared with control treatments. The mean differences were as follows: acupuncture, –.07; 95% confidence interval, 1.3-0.1); doxylamine-pyridoxine, –1.0: 95% CI, 1.6-0.4); combination of both, –1.6; 95% CI, 2.2-0.9). No significant interaction was detected between the interventions (P = .69).Compared with placebo treatments, pharmaceutical therapy resulted in more somnolence, while active acupuncture led to more frequent dyspnea, bruising, itching, and pain. A higher risk of babies born small for gestational age was observed in mothers who took doxylamine-pyridoxine versus placebo: odds ratio, 3.8; 95% CI, 1-14.1). Neither the placebo effects of the sham interventions nor the natural regression of symptoms experienced by many women were evaluated.
 

 

 

Suited to milder symptoms?

Dr. Stika called the study well-designed and well-written but cited several limitations, including the small cohort, the minor symptom improvement, and the lack of a comparator group receiving neither sham nor active treatment.

“Compared with sham combination treatments, the active combination arm was only about a point and a half better,” she said. “And would some women have got better over the 2 weeks anyway with no intervention at all? A large percentage of women with NVP do improve on their own.”

And in terms of acceptability to U.S. women, she cautioned, “The study cohort was entirely Chinese, and this is a population that already accepts acupuncture treatment.”
