How Does Diet Affect Gastroesophageal Reflux Disease?

What dietary recommendations are appropriate for gastroesophageal reflux disease (GERD)? While 85% of patients identify at least one food associated with reflux symptoms, misconceptions about diet in GERD are widespread. The issue was discussed during a dedicated session at the Francophone Days of Hepatology, Gastroenterology, and Digestive Oncology.

GERD occurs when the contents, especially acid, of the stomach back up into the esophagus, leading to symptoms or lesions of the esophageal mucosa.

In addition to proton pump inhibitors, several hygienic-dietary rules are integrated into the therapeutic management of GERD. Some, such as elevating the head of the bed and allowing a 2- to 3-hour gap between meals and bedtime, have proven effective.

Diet and obesity also play a role in the onset of GERD symptoms. Thus, hygienic-dietary rules are an integral part of current recommendations.

“Weight loss is effective in reducing reflux symptoms and should be recommended,” stated Frank Zerbib, MD, head of Hepatology, Gastroenterology, and Digestive Oncology at University Hospital of Bordeaux in France, during the presentation.

Furthermore, most patients with GERD identify foods that may trigger their symptoms, even if there is no evidence to support this in the literature. However, it has been shown that reducing the consumption of these foods is effective.
 

Caloric Intake and Lipid Content

Meal intake affects esophagogastric physiology in several ways: It reduces the tone of the lower esophageal sphincter (LES) and increases the number of transient LES relaxations (TLESRs), which are induced by distension and relaxation of the proximal stomach. These effects are mediated by vagal afferent stimulation and the stretching of the mechanoreceptors of the fundic wall. They are influenced by neuropeptide effects such as cholecystokinin (CCK), which is released in the presence of lipids in the duodenal lumen. Hence, the importance of caloric intake and lipid content, even though it is difficult to distinguish their respective effects.

high-calorie meal slows gastric emptying, thus prolonging gastric distension, reducing LES tone, and promoting the onset of TLESRs. Several studies have emphasized that at equivalent caloric intake, lipid composition has no impact on LES tone and the number of TLESRs in healthy patients or those with GERD. However, with equivalent caloric intake, and thus equivalent acid exposure, the presence of lipids in the meal increases the perception of reflux. This “reflux hypersensitivity” effect induced by lipids is caused by the endogenous release of CCK and its action on vagal afferents. This effect also is observed in the perception of functional dyspepsia symptoms.

Several studies have established a correlation between saturated fat consumption and the presence of GERD symptoms.
 

The Role of Carbohydrates

While the protein component of a meal has little impact on esophagogastric physiology, carbohydrates produce effects on esophagogastric motility that are mediated by their fermentation products, especially short-chain fatty acids (SCFAs), which are synthesized in the colon. Colonic perfusion of these SCFAs leads to fundus relaxation, reduced LES tone, and increased TLESRs. Moreover, in patients with GERD, adding prebiotics (fructo-oligosaccharide) to the meal content increases the number of TLESRs, acid reflux, and symptoms by amplifying colonic fermentation and SCFA production.

Several studies have evaluated low-carbohydrate diets in GERD. A small study of eight patients with morbid obesity on a very low–carbohydrate diet observed benefits on symptoms and esophageal acid exposure in pH probe testing.

A randomized French study of 31 patients with refractory GERD found no significant difference between a low fermentable oligo-, di-, monosaccharides, and polyols diet and usual dietary advice.

A recent American study of 95 veterans found an improvement in pH in the group reducing simple sugars but symptomatic improvement in all groups reducing sugar consumption in general.

Therefore, based on all these data, according to Dr. Zerbib, “high-calorie meals, rich in fats or carbohydrates, promote the onset of reflux episodes and their perception. Diets low in fats and carbohydrates should be recommended.”
 

Questionable Studies

Certain foods can reduce LES pressure, such as coffee (excluding decaf), chocolate, and white wine. Moreover, white wine, beer, and chocolate have been associated with increased esophageal acid exposure. No significant effects on LES pressure or reflux have been observed with the consumption of citrus fruits or spicy foods. These conclusions, however, are based on older studies and subject to methodological criticisms.

Population studies on tea and coffee yield conflicting results. A recent study of 48,000 nurses without documented GERD found that consumption of tea, coffee, or sodas increased the risk for reflux symptoms by about 30% at least once per week, while water, milk, or fruit juice had no effect. Furthermore, the consumption of carbonated beverages also does not seem to increase the risk for GERD.

Regarding alcohol consumption as a risk factor for GERD, epidemiological data do not allow for a definitive conclusion. Most studies have not found a significant link, a finding confirmed by a recent meta-analysis of 24 publications.

Obesity contributes to GERD by promoting increased abdominal pressure and constraints on the esophagogastric junction. A high-resolution manometry study provided robust evidence for this mechanism. Generally, the relative risk for symptomatic GERD with obesity is 2-3 compared with normal body mass index (BMI), with a linear increase according to BMI.

Dr. Zerbib reported no relevant financial conflicts related to his presentation.

Overlord or Underachiever: AI Poised to Disrupt Eye Care

Article Type
Changed

You can’t spell “ophthalmologist” without artificial intelligence (AI) — a fact that might have many eye specialists looking warily over their shoulders. But should they be concerned, or is it time to embrace the new technology?

Ophthalmologists, like most other medical specialists, might be looking warily over their shoulders as AI continues to evolve. But should they be concerned, or is it time to embrace the new technology?

Two recent studies have demonstrated the ability of AI to match ophthalmologists’ answers to patients’ questions about eye disease, and the technology is poised to assist ophthalmologists in managing patient workflow and overcome shortages in the ophthalmic workforce, attendees at the American Glaucoma Society meeting presented on March 2, 2024, in Huntington Beach, California, were told.

study at the Icahn School of Medicine at Mount Sinai in New York City found chatbots matched the proficiency of fellowship-trained ophthalmologists in diagnostic accuracy and completeness in handling questions about eye disease and real patient cases. Another study found a similar result in handling 200 eye care questions from an online chat forum, Robert Chang, MD, co-author of the second study and a glaucoma specialist and associate professor of ophthalmology at Stanford University in Stanford, California, reported.

“Using prompt engineering of ChatGPT, replies to patient online forum questions are becoming so realistic that specialist physicians are having difficulty telling the difference between human- and machine-generated responses,” Dr. Chang said.

The study used questions patients submitted to an online medical forum that received responses from ophthalmologists, then presented those responses plus answers generated by ChatGPT to a panel of eight ophthalmologists and asked them to distinguish between the two. “The accuracy of judging whether you could tell if it was written by AI or a human was about 61%,” Dr. Chang reported. “So most of the time you could not tell the difference.”

The study reported that of 800 evaluations of chatbot-written answers, ophthalmologists rated 21% of them as human-written, while they marked 64.6% of human-written answers as AI-written. The study also found that the likelihood of chatbot answers containing incorrect or inappropriate material was comparable with human answers: Less than 1% for both.

Dr. Chang also referenced a similar, more recent study from the Icahn School of Medicine in which 15 clinicians reviewed answers to patient questions by fellowship-trained glaucoma and retina specialists and those generated by ChatGPT-4, the chatbot model released by OpenAI in the spring of 2023. The study used a statistical tool to evaluate the combined question-case mean rank for accuracy, which was 506.2 for ChatGPT and 403.4 for glaucoma specialists based on 831 question cases. The mean rank for completeness was 528.3 and 398.7, respectively, based on 828 question cases (P < .001).

“The specialists themselves didn’t rate their answers as good as they rated the chatbot answers,” Dr. Chang said. “So it’s really showing that what we can come up with generative AI so human-like that it’s difficult for us to tell the difference on accuracy and completeness.”
 

‘Getting Close’

However, he noted that chatbots still have some kinks to work out with factual errors, difficulty referencing reliable sources, and hallucinations — fabricated material that may not be accurate. “We’re not quite there yet, but it’s getting close,” Dr. Chang added.

Dr. Chang noted that his clinic at Stanford is testing an AI platform to perform virtual scribing of patient encounters in real time. “That can save a lot of time on documentation,” he said. “I think this is a direction moving forward to increase our productivity because as we know, we all have workforce problems whether it’s the doctors or having enough technicians.”

Chatbots also are being tested for scheduling and generating letters. “Because of the unique needs of each ophthalmologist, AI agents that augment the existing workforce on specific administrative tasks will be the most likely early use case rather than autonomous disease screening or clinical decision support tools, which will take longer to validate prospectively in specific cohorts,” he said.

“Any AI today still has a long way to go before it can ingest and verify all the data for independent decision-making and be validated for fairness and generalizability,” Dr. Chang added. “It is much easier to have ‘low-level thinking’, repetitive tasks be taken care of by algorithms first.”

Dr. Chang “made a convincing case for embracing currently feasible applications of AI, highlighting the potential benefits of leveraging LLMs such as ChatGPT to enhance clinical productivity,” said Thasarat Vajaranant, MD, MHA, director of the glaucoma service and of data sourcing and strategy for the AI Ophthalmology Center at Illinois Eye and Ear Infirmary and the University of Illinois Chicago.

“With the growing demands of an aging population and workforce shortages in ophthalmology, AI-driven solutions offer promise in various areas, including telemedicine triage, organizing clinical notes, assisting in assessments and treatment planning, and virtual scribing,” Dr. Vajaranant said. “Rather than fearing this technology, we should approach its integration with caution.”

Dr. Chang disclosed relationships with Alcon, Genentech/Roche, Itnalight, Verana Health, Sight Sciences, Ocular Therapeutix, Glaukos, Carl Zeiss Meditec, and Apple. Dr. Vajaranant had no relevant disclosures.

Money, Ethnicity, and Access Linked to Cervical Cancer Disparities

Article Type
Changed

 

Disparities and geographical variations in cervical cancer outcomes appear to be related to social determinants of health, including socioeconomic status, race or ethnicity, and proximity to facilities skilled at early-stage diagnosis and treatment.

These findings come from analyses of insurance data gathered via the Cervical Cancer Geo-Analyzer tool, a publicly available online instrument designed to provide visual representation of recurrent or metastatic cervical cancer burden across metropolitan statistical areas in the United States over multiple years.

[Reporting the findings of] “this study is the first step to optimize healthcare resources allocations, advocate for policy changes that will minimize access barriers, and tailor education for modern treatment options to help reduce and improve outcomes for cervical cancer in US patients,” said Tara Castellano, MD, an author and presenter of this new research, at the Society of Gynecologic Oncology’s Annual Meeting on Women’s Cancer, held in San Diego.

Seeing Cancer Cases

Dr. Castellano and colleagues previously reported that the Geo-Analyzer tool effectively provides quantified evidence of cervical cancer disease burden and graphic representation of geographical variations across the United States for both incident and recurrent/metastatic cervical cancer.

In the current analysis, Dr. Castellano, of Louisiana State University School of Medicine in New Orleans, discussed potential factors related to cervical cancer incidence and geographic variations.

The study builds on previous studies that have shown that Black and Hispanic women have longer time to treatment and worse cervical cancer outcomes than White women.

For example, in a study published in the International Journal of Gynecologic Cancer, Marilyn Huang, MD, and colleagues from the University of Miami Miller School of Medicine, Miami, Florida, and other centers in Miami looked at time to treatment in a diverse population of 274 women starting therapy for cervical cancer.

They found that insurance type (private, public, or none) contributed to delay in treatment initiation regardless of the treatment modality, and that the patient’s language and institution of diagnosis also influenced time to treatment.

In a separate scientific poster presented at SGO 2024, Dr. Castellano and colleagues reported that, among women with newly diagnosed endometrial cancer, the median time to treatment was 7 days longer for both Hispanic and Black women, compared with non-Hispanic White women. In addition, Black women had a 7-day longer time to receiving their first therapy for advanced disease. All of these differences were statistically significant.

Dr. Castellano told this news organization that the time-to-treatment disparities in the endometrial cancer study were determined by diagnostic codes and the timing of insurance claims.

Reasons for the disparities may include more limited access to care and structural and systemic biases in the healthcare systems where the majority of Black and Hispanic patients live, she said.

Insurance Database

In the new study on cervical cancer, Dr. Castellano and her team defined cervical cancer burden as prevalent cervical cancer diagnosis per 100,000 eligible women enrolled in a commercial insurance plan, Medicaid, or Medicare Advantage. Recurrent or metastatic cancer was determined to be the proportion of patients with cervical cancer who initiated systemic therapy.

 

 

The goals of the study were to provide a visualization of geographical distribution of cervical cancer in the US, and to quantify associations between early or advanced cancers with screening rates, poverty level, race/ethnicity, and access to brachytherapy.

The administrative claims database queried for the study included information on 75,521 women (median age 53) with a first diagnosis of cervical cancer from 2015 through 2022, and 14,033 women with recurrent or metastatic malignancies (median age 59 years).

Distribution of cases was higher in the South compared with in other US regions (37% vs approximately 20% for other regions).

Looking at the association between screening rates and disease burden from 2017 through 2022, the Geo-Analyzer showed that higher screening rates were significantly associated with decreased burden of new cases only in the South, whereas higher screening rates were associated with lower recurrent/metastatic disease burden in the Midwest and South, but a higher disease burden in the West.

In all regions, there was a significant association between decreased early cancer burden in areas with high percentages of women of Asian heritage, and significantly increased burden in areas with large populations of women of Hispanic origin.

The only significant association of race/ethnicity with recurrent/metastatic burden was a decrease in the Midwest in populations with large Asian populations.

An analysis of the how poverty levels affected screening and disease burden showed that in areas with a high percentage of low-income households there were significant associations with decreased cervical cancer screening and higher burden of newly diagnosed cases.

Poverty levels were significantly associated with recurrent/metastatic cancers only in the South.

The investigators also found that the presence of one or more brachytherapy centers within a ZIP-3 region (that is, a large geographic area designated by the first 3 digits of ZIP codes rather than 5-digit city codes) was associated with a 2.7% reduction in recurrent or metastatic cervical cancer burden (P less than .001).

Demographic Marker?

Reasons for disparities are complex and may involve a combination of inadequate health literacy and social and economic circumstances, said Cesar Castro, MD, commenting on the new cervical cancer study.

He noted in an interview that “the concept that a single Pap smear is often insufficient to capture precancerous changes, and hence the need for serial testing every 3 years, can be lost on individuals who also have competing challenges securing paychecks and/or dependent care. Historical barriers such as perceptions of the underlying cause of cervical cancer, the HPV virus, being a sexually transmitted disease and hence a taboo subject, also underpin decision-making. These sentiments have also fueled resistance towards HPV vaccination in young girls and boys.”

Dr. Castro, who is Program Director for Gynecologic Oncology at the Mass General Cancer Center in Boston, pointed out that treatments for cervical cancer often involve surgery or a combination of chemotherapy and radiation, and that side effects from these interventions may be especially disruptive to the lives of women who are breadwinners or caregivers for their families.

“These are the shackles that poverty places on many Black and Hispanic women notably in under-resourced regions domestically and globally,” he said.

The study was supported by Seagen and Genmab. Dr. Castellano disclosed consulting fees from GSK and Nykode and grant support from BMS. Dr. Castro reported no relevant conflicts of interest and was not involved in either of the studies presented at the meeting.

Disparities and geographical variations in cervical cancer outcomes appear to be related to social determinants of health, including socioeconomic status, race or ethnicity, and proximity to facilities skilled at early-stage diagnosis and treatment.

These findings come from analyses of insurance data gathered via the Cervical Cancer Geo-Analyzer tool, a publicly available online instrument designed to provide visual representation of recurrent or metastatic cervical cancer burden across metropolitan statistical areas in the United States over multiple years.

[Reporting the findings of] “this study is the first step to optimize healthcare resources allocations, advocate for policy changes that will minimize access barriers, and tailor education for modern treatment options to help reduce and improve outcomes for cervical cancer in US patients,” said Tara Castellano, MD, an author and presenter of this new research, at the Society of Gynecologic Oncology’s Annual Meeting on Women’s Cancer, held in San Diego.

Seeing Cancer Cases

Dr. Castellano and colleagues previously reported that the Geo-Analyzer tool effectively provides quantified evidence of cervical cancer disease burden and graphic representation of geographical variations across the United States for both incident and recurrent/metastatic cervical cancer.

In the current analysis, Dr. Castellano, of Louisiana State University School of Medicine in New Orleans, discussed potential factors related to cervical cancer incidence and geographic variations.

Maternal Lifestyle Interventions Boost Babies’ Heart Health

Article Type
Changed

Infants born to women with obesity showed improved measures of cardiovascular health when their mothers adopted healthier lifestyles before and during pregnancy, based on data from a systematic review presented at the annual meeting of the Society for Reproductive Investigation.

Previous research has shown that children born to mothers with a high body mass index (BMI) are more likely to die from cardiovascular disease in later life, said presenting author Samuel J. Burden, PhD, in an interview.

“Surprisingly, early signs of these heart issues can start before birth and continue into childhood,” said Dr. Burden, a research associate in the Department of Women & Children’s Health, School of Life Course & Population Sciences, King’s College London, London, United Kingdom.

To examine the effect of interventions such as a healthy diet and exercise in pregnant women with obesity on the heart health of their infants, Dr. Burden and colleagues reviewed data from eight randomized, controlled trials involving diet and exercise for pregnant women with obesity. Of these, two used antenatal exercise, two used diet and physical activity, and one used preconception diet and physical activity. The studies ranged in size from 18 to 404 participants. Two studies included infants younger than 2 months of age, and four studies included children aged 3-7 years.

Overall, lifestyle interventions before conception and before birth were associated with significant changes in cardiac remodeling, specifically reduced interventricular septal wall thickness.

In addition, one of three studies of cardiac diastolic function and four of five studies of systolic function showed significant improvements. The five studies of cardiac systolic function and three studies of diastolic function also showed improvement in systolic and diastolic blood pressure in infants of mothers who took part in the interventions. The studies were limited mainly by large attrition rates, the researchers wrote in their presentation. However, more studies in larger populations that also include older children could confirm the findings and inform public health strategies to promote healthy lifestyles for pregnant women, they noted.

Encourage Healthy Lifestyle Before and During Pregnancy

The evidence supports the findings from animal studies showing that an offspring’s health is influenced by maternal lifestyle before and during pregnancy, Dr. Burden said in an interview. The data suggest that healthcare providers should encourage women with a high BMI who want to become pregnant to eat healthfully and become more active as a way to enhance the future cardiovascular health of their children, he said.

The full results of the current study are soon to be published, but more work is needed, said Dr. Burden. “While we observed a protective effect from these lifestyle programs, there is a need for more extensive studies involving a larger number of women (and their children) who were part of the initial research,” he said. “Additionally, it will be crucial to track these children into adulthood to determine whether these antenatal lifestyle interventions persist in lowering the risk of future cardiovascular disease.”

Beginning healthy lifestyle programs prior to pregnancy might yield the best results for promoting infant cardiovascular health, and more prepregnancy interventions for women with obesity are needed, Dr. Burden added.

The current study adds to the growing body of evidence that the in utero environment can have lifelong effects on offspring, Joseph R. Biggio Jr, MD, system chair of maternal fetal medicine at Ochsner Health, New Orleans, Louisiana, said in an interview.

“Several studies have previously shown that the children of mothers with diabetes, hypertension, or obesity are at increased risk for developing signs of metabolic syndrome and cardiovascular changes during childhood or adolescence,” said Dr. Biggio.

The data from this systematic review support the potential value of interventions aimed at improving maternal weight gain and cardiovascular performance before and during pregnancy that may result in reduced cardiovascular remodeling and myocardial thickening in infants, he said.   

The study was supported by a British Heart Foundation Special Project Grant. The researchers had no financial conflicts to disclose. Dr. Biggio had no financial conflicts to disclose.

Delaying Embryo Transfers May Benefit Patients With Endometrial Polyps

Article Type
Changed

A longer time between hysteroscopic polypectomy and frozen embryo transfer may improve the odds of successful pregnancy, based on data from a new analysis presented at the annual meeting of the Society for Reproductive Investigation.

Although uterine polyps have a negative effect on pregnancy rates, data supporting a specific time interval between hysteroscopic polypectomy (HP) and frozen embryo transfer (FET) are limited, according to Audrey Messelt, MD, of Baylor College of Medicine, Houston, Texas, and colleagues.

“Hysteroscopic polypectomy is a common procedure performed before embryo transfer to optimize the receptivity of the endometrium. Currently, there is no ideal recovery time lapse between surgery and an embryo transfer,” said senior author Laura Detti, MD, professor of obstetrics and gynecology at Baylor, in an interview. “This is often the last step prior to embryo transfer, and identifying a recovery time that allows the best outcome is important.”

In a retrospective analysis, the researchers examined the effect of the time between HP and FET on pregnancy outcomes. They identified 65 patients with uterine pathology based on saline-infusion sonogram who underwent hysteroscopy and FET between June 1, 2022, and September 30, 2023.

The endometrial preparation for FET included sequential administration of oral or transdermal estradiol and intramuscular progesterone.

Overall, 46 patients were diagnosed with endometrial polyps at the time of surgery; three had endometritis, one had a uterine septum that was resected, 15 had no abnormal pathology or had normal endometrium at the time of examination. No cases of hyperplasia or malignancy were identified.

A total of 58 patients underwent FET with a single euploid embryo, four with a single untested embryo, one with a low-mosaic embryo, and two with a double-embryo transfer (one euploid and one low mosaic).

After FET, 50 patients conceived and 15 did not. Patients with ongoing pregnancies who had a history of endometrial polyps had significantly more days from surgery to FET, compared to patients with a history of polyps who failed to conceive (median 70 days vs 45 days, P = .01).

By contrast, the time between hysteroscopy and FET was similar among patients with no endometrial pathology who did and did not have ongoing pregnancies (median 45 vs 52.5 days, P = .95).

The findings were limited by the relatively small sample size and exclusion of patients with pathologies other than polyps, as well as a lack of data on age group breakdowns. However, the results suggest that patients with uterine polyps may benefit from more time between HP and FET, while patients with normal surgical findings could undergo FET sooner, the researchers concluded.
 

Postpolypectomy Timing May Affect Pregnancy Outcomes

“We used to think that having had the first menses from surgery would be enough recovery time for the uterine cavity, even if it was just 2 weeks,” Dr. Detti said in an interview. “This still holds true when no endometrial polyps are diagnosed in the pathological specimen; however, we learned that if endometrial polyps are removed at the time of hysteroscopy, the ideal recovery time prior to an embryo transfer should be longer,” she said.

The current study is important because approximately 15% of women are diagnosed with endometrial polyps during their reproductive years, said Mark P. Trolice, MD, professor at the University of Central Florida, Orlando, and founder/medical director of the IVF Center of Central Florida in Winter Park, in an interview.

“Abnormalities of the uterine cavity have been shown to reduce embryo implantation and increase the risk of miscarriage,” said Dr. Trolice. Although the impact of small endometrial polyps on fertility and pregnancy are uncertain, most infertility specialists recommend removal of endometrial polyps via hysteroscopic polypectomy in general and prior to IVF embryo transfer in particular, he said.

Although infertility patients are anxious to undergo embryo transfer, the current study suggests a benefit in delaying the procedure following the removal of any polyps identified during the pretransfer evaluation, Dr. Trolice said in an interview. As for additional research, “it would be helpful to know the age group breakdown of patients and if the results were consistent among all categories,” he said.

The study received no outside funding. The researchers had no financial conflicts to disclose. Dr. Trolice had no financial conflicts to disclose and serves on the Editorial Advisory Board of Ob.Gyn. News.

However, the results suggest that patients with uterine polyps may benefit from more time between HP and FET, while patients with normal surgical findings could undergo FET sooner, the researchers concluded.
 

Postpolypectomy Timing May Affect Pregnancy Outcomes

“We used to think that having had the first menses from surgery would be enough recovery time for the uterine cavity, even if it was just 2 weeks,” Dr. Detti said in an interview. “This still holds true when no endometrial polyps are diagnosed in the pathological specimen; however, we learned that if endometrial polyps are removed at the time of hysteroscopy, the ideal recovery time prior to an embryo transfer should be longer,” she said.

The current study is important because approximately 15% of women are diagnosed with endometrial polyps during their reproductive years, said Mark P. Trolice, MD, professor at the University of Central Florida, Orlando, and founder/medical director of the IVF Center of Central Florida in Winter Park, in an interview.

“Abnormalities of the uterine cavity have been shown to reduce embryo implantation and increase the risk of miscarriage,” said Dr. Trolice. Although the impact of small endometrial polyps on fertility and pregnancy are uncertain, most infertility specialists recommend removal of endometrial polyps via hysteroscopic polypectomy in general and prior to IVF embryo transfer in particular, he said.

Although infertility patients are anxious to undergo embryo transfer, the current study suggests a benefit in delaying the procedure following the removal of any polyps identified during the pretransfer evaluation, Dr. Trolice said in an interview. As for additional research, “it would be helpful to know the age group breakdown of patients and if the results were consistent among all categories,” he said.

The study received no outside funding. The researchers had no financial conflicts to disclose. Dr. Trolice had no financial conflicts to disclose and serves on the Editorial Advisory Board of Ob.Gyn. News.

A longer time between hysteroscopic polypectomy and frozen embryo transfer may improve the odds of successful pregnancy, based on data from a new analysis presented at the annual meeting of the Society for Reproductive Investigation.

Although uterine polyps have a negative effect on pregnancy rates, data supporting a specific time interval between hysteroscopic polypectomy (HP) and frozen embryo transfer (FET) are limited, according to Audrey Messelt, MD, of Baylor College of Medicine, Houston, Texas, and colleagues.

“Hysteroscopic polypectomy is a common procedure performed before embryo transfer to optimize the receptivity of the endometrium. Currently, there is no ideal recovery time lapse between surgery and an embryo transfer,” said senior author Laura Detti, MD, professor of obstetrics and gynecology at Baylor, in an interview. “This is often the last step prior to embryo transfer, and identifying a recovery time that allows the best outcome is important.”

In a retrospective analysis, the researchers examined the effect of the time between HP and FET on pregnancy outcomes. They identified 65 patients with uterine pathology based on saline-infusion sonogram who underwent hysteroscopy and FET between June 1, 2022, and September 30, 2023.

The endometrial preparation for FET included sequential administration of oral or transdermal estradiol and intramuscular progesterone.

Overall, 46 patients were diagnosed with endometrial polyps at the time of surgery; three had endometritis, one had a uterine septum that was resected, 15 had no abnormal pathology or had normal endometrium at the time of examination. No cases of hyperplasia or malignancy were identified.

A total of 58 patients underwent FET with a single euploid embryo, four with a single untested embryo, one with a low-mosaic embryo, and two with a double-embryo transfer (one euploid and one low mosaic).

After FET, 50 patients conceived and 15 did not. Patients with ongoing pregnancies who had a history of endometrial polyps had significantly more days from surgery to FET, compared to patients with a history of polyps who failed to conceive (median 70 days vs 45 days, P = .01).

By contrast, the time between hysteroscopy and FET was similar among patients with no endometrial pathology who did and did not have ongoing pregnancies (median 45 vs 52.5 days, P = .95).

The findings were limited by the relatively small sample size and exclusion of patients with pathologies other than polyps, as well as a lack of data on age group breakdowns. However, the results suggest that patients with uterine polyps may benefit from more time between HP and FET, while patients with normal surgical findings could undergo FET sooner, the researchers concluded.

‘From Interpretation to Action’: Using CGM to Manage T2D

Article Type
Changed

Data derived from continuous glucose monitoring (CGM) devices can help guide nutrition management and insulin dosing in people with type 2 diabetes (T2D) in primary care settings.

At the Advanced Technologies & Treatments for Diabetes meeting, two experts from the International Diabetes Center – HealthPartners Institute, Minneapolis, offered advice for clinicians. Tara Ettestad, RN, LD, CDCES, program manager for care transformation and training at the center, shared tips for helping patients change their diet based on CGM readings. The center’s medical director Thomas Martens, MD, provided a systematic approach to using CGM to guide adjustment of insulin doses and other medications for insulin-treated patients with T2D.
 

CGM-Guided Nutrition: Focus on Sustainable Changes

With CGM, people with diabetes get real-time feedback about the impact of foods on their glucose levels. This can help them learn not just what they can’t eat but what they can eat, Ms. Ettestad pointed out.

“People want to know what to eat. This is the number-one question that people who are newly diagnosed with diabetes ask, and unfortunately, they typically hear what not to eat. No carbohydrates, no sugar, no white foods, no sweets. This can be really disheartening and confusing for many. We should be focusing on sustainable changes to help improve diets,” she said.

She added, “Not everyone can see a dietitian, but all clinicians can help provide evidence-based nutrition guidance.”

When guiding patients, it’s important to focus on the four “core concepts” outlined in the American Diabetes Association’s nutrition consensus report:

  • Emphasize nonstarchy vegetables
  • Minimize added sugars and refined grains
  • Eat more whole foods, less highly processed foods
  • Replace sugar-sweetened beverages with water as often as possible

With CGM, patients can see the differences in response to refined carbs (wheat, rice, and potato), sugars (sucrose, fructose, and glucose), and resistant starches (whole grains, fruits, and legumes). Typically, glucose responses are steeper and higher for the first two compared to resistant starches.

CGM can also show the effects of eating fat and protein, in that they can delay glucose responses to meals even with the same carbohydrate content, Ms. Ettestad said.

It’s important to remind patients that although one goal of using CGM is to reduce post-meal glucose spikes, eating a lot of high-saturated fat, high-calorie foods isn’t the healthful way to do it. “What’s really important when we’re using CGM to help guide nutrition is remembering nutrition quality and what can be good for glucose is not always good for our overall health,” Ms. Ettestad stressed.

She provided these further tips:

  • Pick one meal at a time to focus on. Collaborate with patients to see what changes they are able and willing to make. For example, rather than entirely giving up rice or noodles at dinner, try eating less of those and adding more vegetables.
  • Suggest that patients keep a food log or use a tracking app so that the source of specific glucose patterns can be identified and addressed.
  • Show patients how to check their time in range (TIR) on their mobile device or reader each week so they can see big-picture results of their changes. “This can be really motivating for people to see,” she said.
  • Remind people that glucose rises with meals. This seems obvious but may not be to those newly diagnosed, she pointed out.
  • Educate patients on glucose targets and explain that other factors such as stress and activity can influence glucose levels.
  • Focus on the positive. “What have you been learning about how your meals and beverages affect your glucose?”
  • Help guide patients toward better diet quality, even when TIR is a goal, using the four core concepts.
  • Encourage curiosity, such as by experimenting with portions, timing, or food order. “What if you try eating nonstarchy foods first?”
  • Before adjusting a medication dose, consider asking if the patient is willing to make a nutrition change. “Every visit is an opportunity!”
 

 

Adjusting Insulin With the Help of CGM: Focus on Four Patient Subgroups

Dr. Martens noted that about a quarter of people with T2D will require insulin treatment, despite increasing use of sodium-glucose cotransporter 2 (SGLT2) inhibitors and glucagon-like peptide 1 (GLP-1) receptor agonists. And even when insulin is used as a “salvage therapy” in T2D, about two thirds of those individuals still struggle to achieve an A1c below 7% with or without other glucose-lowering medications, he noted.

“So, we have this huge population with type 2 diabetes who have limited access to endocrinology, and advanced insulin delivery devices are not yet available for them. Can better use of CGM drive improvements in care?”

He pointed to MOBILE, a randomized clinical trial, which showed that CGM use resulted in significantly improved A1c at 8 months compared with fingerstick monitoring among adults with T2D taking long-acting insulin alone without premeal insulin. However, TIR was still just 59% (vs 43% with fingerstick testing), suggesting room for improvement.

“This could have been much, much better…Rapid interpretation isn’t really enough. We need to move from interpretation into action,” Dr. Martens said.

His team recently developed a program called “CGM Clinician Guided Management (CCGM)” aimed at primary care that encourages the following principles:

  • Appropriate movement toward the safer “high value” noninsulin therapies, that is, GLP-1 agonists and SGLT2 inhibitors.
  • Appropriate insulin titration.
  • Appropriate cycle time in titration, that is, accelerating more rapidly when one dose isn’t working. “That’s the Achilles heel of primary care,” he noted.
  • Quick identification of when the limits of basal insulin therapy have been reached.
  • Team-based management for difficult situations and for individuals on multiple daily injections and mealtime insulin regimens. “This is a group that really struggles…in primary care settings,” he noted.

The following three steps are based on published T2D management guidelines:

  • Step 1: If the patient has atherosclerotic cardiovascular disease, start with either an SGLT2 inhibitor or GLP-1 agonist. For those with congestive heart failure and/or chronic kidney disease, SGLT2 inhibitors are indicated.
  • Step 2: Is the patient on sulfonylurea? Consider eliminating it before moving to CGM-based insulin titration.
  • Step 3: Was there a change in therapy based on steps 1 or 2? If not, move to CGM-guided insulin titration. If yes, wait 2-4 weeks to see the impact of therapy change before moving on.

The program categorizes patients into one of four groups based on CGM data, with respective management approaches:

  • Category 1: TIR > 70%, time below range (TBR) < 3%: Doing well, keep on going!
  • Category 2: TIR > 70%, TBR ≥ 3%: Too much hypoglycemia, need to decrease therapy. Stop sulfonylureas, and if TBR > 10%, also decrease basal insulin dose.
  • Category 3: TIR < 70%, TBR < 3%: Too much hyperglycemia — increase therapy.
  • Category 4: TIR < 70%, TBR ≥ 3%: This is the toughest category. Fix or advance therapy. These patients should be either referred to a diabetes care and education specialist (formerly known as “diabetes educators”) to troubleshoot their regimens or have their therapy advanced to multiple daily injections. The hypoglycemia should be addressed first for safety, then the hyperglycemia.

“We hope that CCGM is going to be the translation of CGM data into action in primary care, where we struggle with action and inaction,” Dr. Martens said. It’s expected to be posted on the IDC website soon.

Ms. Ettestad’s employer received educational grant funds from Abbott Diabetes Care and Sanofi-Aventis Groupe. She also worked as a product trainer with Tandem Diabetes Care. She is employed by nonprofit International Diabetes Center – HealthPartners Institute and received no personal income or honoraria from these activities. Dr. Martens’ employer received funds on his behalf for research and speaking support from Dexcom, Abbott Diabetes Care, Medtronic, Insulet, Tandem, Sanofi, Lilly, and Novo Nordisk and for consulting from Sanofi and Lilly.

Think Beyond the ‘Go-Tos’ for Wart Management, Expert Advises

Article Type
Changed

— When Jennifer Adams, MD, recently entered the search term “warts” on the ClinicalTrials.gov web site, nearly 240 results popped up.

“There is a lot of research activity around this topic,” Dr. Adams, vice chair of the department of dermatology at the University of Nebraska Medical Center, said at the annual meeting of the American Academy of Dermatology. “We just don’t have fantastic, well-run trials on many of the currently available treatments.”

In a 2012 Cochrane review on the topical treatment of non-genital cutaneous warts, authors drew from 85 trials involving 8,815 randomized patients. They found that most warts spontaneously resolved, and the authors determined salicylic acid to be safe and modestly beneficial. Specifically, trials of salicylic acid (SA) versus placebo showed that the former significantly increased the chance of clearance of warts at all sites (risk ratio, 1.56, 95% confidence interval [CI], 1.20-2.03). A meta-analysis of cryotherapy versus placebo for warts at all sites favored neither intervention nor control (RR, 1.45, 95% CI, 0.65-3.23).

“The authors determined that there is less evidence for cryotherapy but stated that it may work when salicylic acid does not, or in combination with salicylic acid,” Dr. Adams said. “However, salicylic acid and cryotherapy don’t do enough for our patients [with warts]. There are a lot of situations where we need to reach further into the toolbox.”

A 2021 review article listed many options for managing difficult-to-treat warts, including intralesional Candida antigen, intralesional measles-mumps-rubella (MMR), intralesional HPV vaccine, intralesional vitamin D, intralesional cidofovir, intralesional bleomycin, and intralesional 5-FU injections, and topical vitamin D, topical cidofovir, and topical bleomycin. According to Dr. Adams, clinical data exist for cidofovir and vitamin D but studies evaluated different formulations, doses, sites of administration, and limited randomized controlled trials.

“Intralesional cidofovir is more effective than the topical form, but intralesional cidofovir can be painful and both forms are expensive,” she said. “Topical vitamin D is less likely to cause dyspigmentation compared to other available treatments, so it’s a great option in skin of color, but it has been less effective compared to some of our other topical treatments.”

Newer Options Promising

On the horizon, berdazimer gel was approved in January of 2024 for the treatment of molluscum but results from trials of its use for extragenital warts are encouraging. Another promising option is topical ionic contraviral therapy (ICVT) with digoxin and furosemide combined, which inhibits cellular potassium influx. A phase 2a randomized controlled trial of 80 adults found a statistically significant reduction in the diameter of cutaneous warts among those who received ICVT compared with those who received placebo (P = .002). “It’s cheap and well tolerated,” Dr. Adams added.

Intralesional approaches to treating warts offer another alternative. A 2020 review of 43 articles concluded that intralesional treatments for warts have equal or superior efficacy to first-line salicylic acid or cryotherapy.

Dr. Adams said that she considers intralesional treatments such as vitamin D, MMR vaccine antigen, and Candida antigen for refractory, numerous, or distant site warts. “Injecting the MMR vaccine into the largest wart every 2 weeks has been found to lead to complete clearance in 60%-68% of cases in one study,” she said. “The benefit is that it’s $21 per dose, which is nice, but as with any vaccination, patients can develop flu-like symptoms as side effects.”

Use of the HPV vaccine for treating cutaneous warts remains controversial, she continued, but it seems to work better in younger patients. In one open-label study that evaluated the HPV vaccine for the treatment of multiple recalcitrant warts, with doses administered at 0. 2, and 6 months, the response rate 3 months after the third dose was 55% among those older than age 26, compared with 84% among those ages 9-26 years.

Another option, intralesional cidofovir, has been shown to be especially effective for refractory warts. “It has also been shown to work for warts in immunocompetent and immunocompromised patients,” Dr. Adams said.

In the realm of adjuvant treatments, microneedling has been found to have similar efficacy to needling, Dr. Adams said, but with minimal pain. “When we combine it with topical treatments like 5-FU, it’s even more efficacious,” she said.

One study found that combining microneedling with topical 5-FU had clearance similar to that of intralesional 5-FU or microneedling alone, but involved fewer treatment sessions and less pain in the combination group.

Autoinoculation has been used to stimulate an immune response in patients with warts, leading to clearance rates of 4% (mild clearance) to 66% (complete clearance) in one study. “We would expect this to work better in immunocompetent patients, but it’s something to keep in mind if you’re limited in the medications you can get for a patient,” Dr. Adams said. Also, results from a systematic review and meta-analysis suggest that systemic retinoids combined with intralesional immunotherapy leads to higher clearance rates and lower rates of recurrence of warts. The top performer among those tested was acitretin plus Candida antigen.

Dr. Adams advised dermatologists who try alternatives to salicylic acid and cryotherapy for warts to be “wary of a lack of high-level evidence” for their use. “They can be helpful for patients who have failed traditional therapies or have a contraindication to the usual go-tos.”

She reported having no relevant financial disclosures.

— When Jennifer Adams, MD, recently entered the search term “warts” on the ClinicalTrials.gov web site, nearly 240 results popped up.

“There is a lot of research activity around this topic,” Dr. Adams, vice chair of the department of dermatology at the University of Nebraska Medical Center, said at the annual meeting of the American Academy of Dermatology. “We just don’t have fantastic, well-run trials on many of the currently available treatments.”

In a 2012 Cochrane review on the topical treatment of non-genital cutaneous warts, authors drew from 85 trials involving 8,815 randomized patients. They found that most warts spontaneously resolved, and the authors determined salicylic acid to be safe and modestly beneficial. Specifically, trials of salicylic acid (SA) versus placebo showed that the former significantly increased the chance of clearance of warts at all sites (risk ratio, 1.56, 95% confidence interval [CI], 1.20-2.03). A meta-analysis of cryotherapy versus placebo for warts at all sites favored neither intervention nor control (RR, 1.45, 95% CI, 0.65-3.23).

“The authors determined that there is less evidence for cryotherapy but stated that it may work when salicylic acid does not, or in combination with salicylic acid,” Dr. Adams said. “However, salicylic acid and cryotherapy don’t do enough for our patients [with warts]. There are a lot of situations where we need to reach further into the toolbox.”

A 2021 review article listed many options for managing difficult-to-treat warts, including intralesional Candida antigen, intralesional measles-mumps-rubella (MMR), intralesional HPV vaccine, intralesional vitamin D, intralesional cidofovir, intralesional bleomycin, and intralesional 5-FU injections, and topical vitamin D, topical cidofovir, and topical bleomycin. According to Dr. Adams, clinical data exist for cidofovir and vitamin D but studies evaluated different formulations, doses, sites of administration, and limited randomized controlled trials.

“Intralesional cidofovir is more effective than the topical form, but intralesional cidofovir can be painful and both forms are expensive,” she said. “Topical vitamin D is less likely to cause dyspigmentation compared to other available treatments, so it’s a great option in skin of color, but it has been less effective compared to some of our other topical treatments.”

Formulation of Sclerotherapy Agent Found Useful for Submental Fat Reduction

Article Type
Changed

— A novel formulation of polidocanol, an injectable synthetic non-ionic detergent that is approved by the US Food and Drug Administration (FDA) for sclerotherapy, may have a role in excess submental fat reduction, results from a phase 2b trial demonstrated.

The solution, also known as 10XB101, “has been demonstrated to cause adipolysis,” Kavita Darji, MD, an American Society for Dermatologic Surgery (ASDS) cosmetic and dermatologic laser surgery fellow at a practice in San Diego, said during a late-breaking session at the annual meeting of the American Academy of Dermatology. “It shows less inflammation and release of cytokines TNF-alpha and MCP-1 by macrophages than deoxycholic acid, which is currently used for submental fat reduction.”

In a phase 2b clinical trial conducted at four sites, investigators enrolled 51 patients and assigned them to one of four dose cohorts: 2%, 3%, or 4.5% 10XB101, or vehicle. Each treatment consisted of up to 50 injections at 0.2 mL per injection, and they were administered up to six times 4 weeks apart. Study endpoints included a composite of the Clinician Submental Fat Score (CSFS) and Patient Submental Fat Score (PSFS) on a 0-4–point scale. The researchers graded local skin reactions such as erythema, edema, tenderness on palpation, bruising, pain, and burning/stinging as 0 (none), 1 (mild), 2 (moderate), or 3 (severe). They also obtained lab tests and performed electrocardiograms.

Dr. Darji and colleagues analyzed two populations: the intent to treat (ITT) population, which included all 51 enrolled subjects who received any injection of the test agent, and a completer population of 40 subjects. “These patients had at least four treatments or completed the treatments per protocol, completed the 4 weeks after final treatment assessments, or did not have any significant protocol deviations that would impact the evaluation of efficacy,” she explained.

To compare how 10XB101 performed compared with deoxycholic acid (Kybella), which is approved by the FDA to improve the appearance of moderate to severe submental fat, the researchers drew from pooled findings of Refine 1 and 2, in which adults received up to six treatment sessions with deoxycholic acid or placebo.

The ITT analysis of the 3% and 4.5% 10XB101 dose groups showed about a fourfold increase in a 2-grade or better improvement in the composite endpoint relative to the pooled findings of deoxycholic acid (62% vs. 16%, respectively). In addition, 80% of the completer population achieved a 2-grade improvement in the composite endpoint. “Importantly, 10% to 33% also received a 3-grade improvement, depending on the dose they were assigned to,” Dr. Darji said.

On average, patients in both cohorts achieved a 1-grade improvement after two treatments, and about 50% achieved a 2-grade improvement after four treatments — which is consistent with a more rapid onset when compared with deoxycholic acid, she said.



Both study endpoints were achieved by 31% of patients in the ITT group vs. 33% of completers, respectively, with the 2% dose; 62% vs. 80% with the 3% dose; and 54% vs. 79% for the 4.5% dose. “This is a 2- to 5-times increase in success” when compared with the results of deoxycholic acid in the published pooled analysis, Dr. Darji said. The researchers measured adverse events by spontaneous and elicited reports and by assessments of recorded local skin reactions. They found that 80% of all measured local skin reactions rated as 0 while 98% of all measured local skin reactions rated as a 0 or 1. One myocardial infarction occurred, which was mild and resolved. This case was not related to the study drug, Dr. Darji said in an interview after the meeting. Otherwise, no safety laboratory or ECG signals were noted.

In findings limited to the 3% dose of 10XB101, mild bruising occurred in 8% of patients at postinjection visit 2, 18% of those at postinjection visit 3, 20% of those at postinjection visit 4, and in 20% of those at postinjection visit 5. Reports of mild pain/burning/stinging occurred in 8% of patients at postinjection visit 2 but at no other subsequent visits. Meanwhile, edema occurred in 42% of patients at postinjection visit 2, 45% of those at postinjection visit 3, 50% of those at postinjection visits 4 and 5, and 38% of those at postinjection visit 6.

“Patients resumed normal activity within 1-3 days and had fewer side effects that lasted longer than 30 days,” Dr. Darji concluded, adding that the results “imply a potential opportunity to expand the treatment to other anatomic areas, which is a future direction.”

One of the session moderators, Andrew Blauvelt, MD, MBA, of Oregon Medical Research Center, Portland, noted that the study was not a head-to-head trial of polidocanol vs. deoxycholic acid, so he cautioned against drawing strong conclusions about the comparative data presented.

Asked to comment on the results Lawrence J. Green, MD, of the department of dermatology at George Washington University, Washington, said that 10XB101 “showed excellent efficacy with much fewer adverse events when compared to what we found in studies with Kybella, the only currently FDA-approved injection for submental fat reduction.”

In addition, “much less pain after injection was to me the most obvious differentiator between this and Kybella studies. I look forward to seeing if larger studies confirm the efficacy and safety from this phase 2 study, as 10XB101 has potential to be a more effective, and safer option to reduce submental fat,” he added. He was not involved with the study.

Dr. Darji reported having no disclosures. Mitchel P. Goldman, MD, the study’s lead investigator, is a minority investor in 10XBio, which is developing 10XB101. Dr. Blauvelt and Dr. Green disclosed conflicts of interest from many pharmaceutical companies.

CORRECTED April 16, 2024 // An earlier version of this article stated incorrect percentages of patients who never received any biologics during the study's 3-year period but improved rapidly or moderately.

Early initiation of biologics — within the first 2 months of symptom presentation — appears to have a significant impact on how rapidly patients with juvenile idiopathic arthritis (JIA) improve, according to findings presented at the annual scientific meeting of the Childhood Arthritis and Rheumatology Research Alliance.

“Our study provides evidence that early use of biologics can significantly alter the disease trajectory of patients with JIA,” Mei-Sing Ong, PhD, of Harvard Medical School, Boston, told attendees. At the same time, however, not all patients who improved rapidly during a 3-year follow-up period needed biologics, a finding that Ong said the researchers are continuing to investigate.

Marinka Twilt, MD, MScE, PhD, chair of CARRA’s JIA Research Committee and a pediatric rheumatologist and clinician scientist at Alberta Children’s Hospital in Calgary, Canada, was not involved in the research but said the continued sustained remission in patients who improved rapidly is very reassuring.

“We always wonder if initial response will be sustained or if patients tend to flare after the initial treatment,” Dr. Twilt told this news organization. “To see the sustained response up to 3 years is fantastic.” She added that it would be enlightening to see more information about patients who rapidly improved over 3 years, including whether they were still taking a [conventional disease-modifying antirheumatic drug (DMARD)] and/or biologic.

“A new diagnosis can be overwhelming for families, and this sometimes leads to step-up therapy to not overwhelm them more with information on new drugs,” Dr. Twilt said. “This study shows that an earlier start is beneficial, and this should be discussed with families early on so there is less delay in early treatment.”

Canada and many US states currently require 3 months of conventional DMARD treatment before patients can start a biologic, Dr. Twilt said, yet “this study shows the additive benefit of using a biologic within 2 months of starting a DMARD, which hopefully will lead to insurance companies adopting this threshold.”

The STOP-JIA study is a prospective observational study that compares the effectiveness of three different treatment plans for JIA. A Step-Up cohort of 257 patients received conventional antirheumatic monotherapy initially, with a biologic added at 3 months or later as needed. The Early Combination cohort of 100 patients received conventional antirheumatic therapy with a biologic from the start. The Biologic First cohort of 43 patients began taking a biologic as a first-line therapy.

In previously reported results of the study at 12 months’ follow-up, there was no significant difference between the Step-Up and Biologic First groups, but there were significant differences between the Step-Up and Early Combination groups. Significantly more patients in the Early Combination group (58.8%) than in the Step-Up group (42.8%) had inactive disease, based on the clinical Juvenile Arthritis Disease Activity Score 10 (cJADAS-10) (= .03). Similarly, 81% of Early Combination patients achieved the American College of Rheumatology 70% improvement criteria, compared with 62% of the Step-Up patients (= .01).

To learn whether the timing of starting a biologic influenced the disease trajectory over time, the researchers compared subgroups of patients with similar trajectories.

“Assessing treatment outcomes at a single point in time does not give us a complete picture of the effects of treatment on disease trajectory, which is an important outcome given that JIA is characterized by a relapsing-remitting course,” Dr. Ong told attendees.

Patients were sorted in the slow, moderate, or rapid improvement trajectories. In previously reported data at 12 months’ follow-up, patients’ odds of achieving rapid improvement were 3.6 times greater if they had started a biologic within 3 months.

This study compared patients’ trajectories over 3 years in the 259 patients (65% of the original cohort) who had at least one cJADAS-10 assessment in each year of follow-up. Most patients (66.8%) were in the rapid improvement class, with 25.9% in the moderate improvement class and 7.3% in the slow improvement class.

Patients in the rapid improvement group achieved inactive disease (cJADAS-10 of 2.5 or less) within 1 year and maintained inactive disease through the second and third years. The moderate and low improvement groups both had higher disease activity at baseline, but the moderate group continued to improve in years 2 and 3, with minimal disease by year 3, on the basis of the cJADAS-10 scores of 2.5-5. The slow group continued to experience moderate disease activity during years 2 and 3.

The findings also revealed that the earlier patients began a biologic, the more likely they were to be in the rapid improvement group than the slow improvement group. Participants who started a biologic in the first month had more than five times greater odds of being in the rapid improvement group than in the slow improvement group (odds ratio [OR], 5.33; = .017).

Those who started a biologic in the second month were also more likely to be in the rapid improvement group (OR, 2.67; = .032). For those who began a biologic by the third month, the odds of improving rapidly were not statistically significant, though Ong noted that could have been because of the small sample size. There was also no significant difference between those who improved moderately vs slowly based on when a biologic was initiated.

It would be helpful to learn whether any of the patients in the rapid improvement group were able to stop medications or whether they all continued treatment during the 3 years of follow-up, Dr. Twilt said. “Does early treatment with biologics not only lead to early remission after initiation but also to the possibility of stopping treatment earlier and remaining in remission?” she asked.

The researchers also found that not all patients needed biologics to end up in the rapid improvement group. Among patients who never received any biologics during the 3-year period, 83% improved rapidly and 17% improved moderately. Yet the researchers identified no significant differences in demographics or clinical factors between patients who received biologics and those who did not.

“The fact that there is a group of patients in the rapid response group who never need a biologic is of great interest, as we always want to treat patients early with the medications they need, but we also want to avoid overtreating patients,” Dr. Twilt said. It’s important to find out what differentiates those patients and whether it is possible to predict which patients do not need biologics early on, she said.

Dr. Ong said the research team is working to develop machine learning methods to improve risk stratification in hopes of addressing that question.

Dr. Ong and Dr. Twilt reported no disclosures. The research was funded by CARRA and the Patient-Centered Outcomes Research Institute.

It Takes a Village: Treating Patients for NSCLC Brain Metastases

Article Type
Changed

Treatment decisions about the care of patients with non–small cell lung cancer (NSCLC) that has metastasized to the brain should always be made by a multidisciplinary team, according to a lung cancer research specialist.

The care of these patients can be quite complex, and the brain is still largely terra incognita, said Lizza Hendriks, MD, PhD, during a case-based session at the European Lung Cancer Congress (ELCC) 2024 in Prague, Czech Republic.

The approach to patients with NSCLC metastatic to the brain and central nervous system was the subject of the session presented by Dr. Hendriks of Maastricht University Medical Center in Maastricht, the Netherlands. During this session, she outlined what is known, what is believed to be true, and what is still unknown about the treatment of patients with NSCLC that has spread to the CNS.

“Immunotherapy has moderate efficacy in the brain, but it can result in long-term disease control,” she said. She added that the best treatment strategy using these agents, whether immunotherapy alone or combined with chemotherapy, is still unknown, even when patients have high levels of programmed death protein 1 (PD-1) in their tumors.

“Also, we don’t know the best sequence of treatments, and we really need more preclinical research regarding the tumor microenvironment in the CNS,” she said.

Next-generation tyrosine kinase inhibitors (TKIs) generally have good intracranial efficacy, except for KRAS G12C inhibitors, which need to be tweaked for better effectiveness in the brain. The optimal sequence for TKIs also still needs to be determined, she continued.
 

Decision Points

Dr. Hendriks summarized decision points for the case of a 60-year-old female patient, a smoker, who in February of 2021 was evaluated for multiple asymptomatic brain metastases. The patient, who had good performance status, had a diagnosis of stage IVB NSCLC of adenocarcinoma histology, with a tumor positive for a KRAS G12C mutation and with 50% of tumor cells expressing PD-1.

The patient was treated with whole-brain radiation therapy and single-agent immunotherapy, and, 8 months later, in October 2021, was diagnosed with extracranial progressive disease and was then started on the KRAS G12c inhibitor sotorasib (Lumakras).

In May 2023 the patient was diagnosed with CNS oligoprogressive disease (that is, isolated progressing lesions) and underwent stereotactic radiotherapy. In June 2023 the patient was found to have progressive disease and was then started on platinum-based chemotherapy, with disease progression again noted in December of that year. The patient was still alive at the time of the presentation.

The first decision point in this case, Dr. Hendriks said, was whether to treat the patient at the time of diagnosis of brain metastases with upfront systemic or local therapy for the metastases.

At the time of extracranial progressive disease, should the treatment be another immumotherapy, chemotherapy, or a targeted agent?

“And the last decision is what should we do [in the event of] CNS oligoprogression?,” she said.
 

First Decision

For cases such as that described by Dr. Hendriks the question is whether upfront local therapy is needed if the patient is initially asymptomatic. Other considerations concerning early local therapy include the risks for late toxicities and whether there is also extracranial disease that needs to be controlled.

If systemic therapy is considered at this point, clinicians need to consider intracranial response rates to specific agents, time to onset of response, risk of pseudoprogression, and the risk of toxicity if radiotherapy is delayed until later in the disease course.

“I think all of these patients with brain metastases really deserve multidisciplinary team decisions in order to maintain or to [move] to new treatments, improve the quality of life, and improve survival,” she said.

In the case described here, the patient had small but numerous metastases that indicated the need for extracranial control, she said.

European Society of Medical Oncology (ESMO) guidelines recommend that asymptomatic patients or those with oligosymptomatic NSCLC brain metastases with an oncogenic driver receive a brain-penetrating TKI. Those with no oncogenic drive but high PD-1 expression should receive upfront immunotherapy alone, while those with PD-1 ligand 1 (PD-L1) expression below 50% receive chemoimmunotherapy.

The joint American Society of Clinical Oncology (ASCO), Society for Neuro-Oncology (SNO), and American Society for Radiation Oncology (ASTRO) guideline for treatment of brain metastases recommends a CNS-penetrating TKI for patients with asymptomatic NSCLC brain metastases bearing EGFR or ALK alterations. If there is no oncogenic driver, the guideline recommends the option of pembrolizumab (Keytruda) with or without chemotherapy.

Both the US and European guidelines recommend initiating local treatment for patients with symptomatic metastases. The level of evidence for these recommendations is low, however.

Clinicians still need better evidence about the potential for upfront immunotherapy for these patients, more information about the NSCLC brain metastases immune environment and tumor microenvironment, data on the best treatment sequence, and new strategies for improving CNS penetration of systemic therapy, Dr. Hendriks said.
 

Second Decision

At the time of CNS progression, the question becomes whether patients would benefit from targeted therapy or chemotherapy.

“We quite often say that chemotherapy doesn’t work in the brain, but that’s not entirely true,” Dr. Hendriks said, noting that, depending on the regimen range, brain response rates range from 23% to as high as 50% in patients with previously untreated asymptomatic brain metastases, although the median survival times are fairly low, on the order of 4 to almost 13 months.

There is also preclinical evidence that chemotherapy uptake is higher for larger brain metastases, compared with normal tissue and cerebrospinal fluid, “so the blood-brain barrier opens if you have the larger brain metastases,” she said.

KRAS-positive NSCLC is associated with a high risk for brain metastases, and these metastases share the same mutation as the primary cancer, suggesting potential efficacy of KRAS G12c inhibitors. There is preclinical evidence that adagrasib (Krazati) has CNS penetration, and there was evidence for intracranial efficacy of the drug in the KRYSTAL-1b trial, Dr. Hendriks noted.

There are fewer data for the other Food and Drug Administration (FDA)–approved inhibitor, sotorasib, but there is evidence to suggest that its brain activity is restricted by ABCB1, a gene encoding for a transporter protein that shuttles substances out of cells.
 

Third Decision

For patients with CNS oligoprogression, the question is whether to adapt systemic therapy or use local therapy.

There is some evidence to support dose escalation for patients with oligoprogression of tumors with EGFR or ALK alterations, but no data to support such a strategy for those with KRAS alterations, she said.

In these situations, data support dose escalation of osimertinib (Tagrisso), especially for patients with leptomeningeal disease, and brigatinib (Alunbrig), but there is very little evidence to support dose escalation for any other drugs that might be tried, she said.

In the question-and-answer part of the session, Antonin Levy, MD, from Gustave Roussy in Villejuif, France, who also presented during the session, asked Dr. Hendriks what she would recommend for a patient with a long-term response to chemoimmunotherapy for whom treatment cessation may be recommended, but who still has oligopersistent brain metastases.

“The difficulty is that with immunotherapy patients can have persistent lesions without any tumor activity, and in the brain I think there is no reliable technique to evaluate this type of thing,” she said.

Dr. Hendriks added that she would continue to follow the patient, but also closely evaluate disease progression by reviewing all scans over the course of therapy to determine whether the tumor is truly stable, follow the patient with brain imaging, and then “don’t do anything.”

Dr. Hendriks disclosed grants/research support and financial relationships with multiple companies. Dr. Levy disclosed research grants from Beigene, AstraZeneca, PharmaMar, and Roche.

There is preclinical evidence that adagrasib (Krazati) has CNS penetration, and there was evidence for intracranial efficacy of the drug in the KRYSTAL-1b trial, Dr. Hendriks noted.

There are fewer data for the other Food and Drug Administration (FDA)–approved inhibitor, sotorasib, but there is evidence to suggest that its brain activity is restricted by ABCB1, a gene encoding for a transporter protein that shuttles substances out of cells.
 

Third Decision

For patients with CNS oligoprogression, the question is whether to adapt systemic therapy or use local therapy.

There is some evidence to support dose escalation for patients with oligoprogression of tumors with EGFR or ALK alterations, but no data to support such a strategy for those with KRAS alterations, she said.

In these situations, data support dose escalation of osimertinib (Tagrisso), especially for patients with leptomeningeal disease, and brigatinib (Alunbrig), but there is very little evidence to support dose escalation for any other drugs that might be tried, she said.

In the question-and-answer part of the session, Antonin Levy, MD, from Gustave Roussy in Villejuif, France, who also presented during the session, asked Dr. Hendriks what she would recommend for a patient with a long-term response to chemoimmunotherapy for whom treatment cessation may be recommended, but who still has oligopersistent brain metastases.

“The difficulty is that with immunotherapy patients can have persistent lesions without any tumor activity, and in the brain I think there is no reliable technique to evaluate this type of thing,” she said.

Dr. Hendriks added that she would continue to follow the patient, but also closely evaluate disease progression by reviewing all scans over the course of therapy to determine whether the tumor is truly stable, follow the patient with brain imaging, and then “don’t do anything.”

Treatment decisions about the care of patients with non–small cell lung cancer (NSCLC) that has metastasized to the brain should always be made by a multidisciplinary team, according to a lung cancer research specialist.

The care of these patients can be quite complex, and the brain is still largely terra incognita, said Lizza Hendriks, MD, PhD, during a case-based session at the European Lung Cancer Congress (ELCC) 2024 in Prague, Czech Republic.

The approach to patients with NSCLC metastatic to the brain and central nervous system was the subject of the session presented by Dr. Hendriks of Maastricht University Medical Center in Maastricht, the Netherlands. During this session, she outlined what is known, what is believed to be true, and what is still unknown about the treatment of patients with NSCLC that has spread to the CNS.

“Immunotherapy has moderate efficacy in the brain, but it can result in long-term disease control,” she said. She added that the best treatment strategy using these agents, whether immunotherapy alone or combined with chemotherapy, is still unknown, even when patients have high levels of programmed death protein 1 (PD-1) in their tumors.

“Also, we don’t know the best sequence of treatments, and we really need more preclinical research regarding the tumor microenvironment in the CNS,” she said.

Next-generation tyrosine kinase inhibitors (TKIs) generally have good intracranial efficacy, except for KRAS G12C inhibitors, which need to be tweaked for better effectiveness in the brain. The optimal sequence for TKIs also still needs to be determined, she continued.
 

Decision Points

Dr. Hendriks summarized decision points for the case of a 60-year-old female patient, a smoker, who in February of 2021 was evaluated for multiple asymptomatic brain metastases. The patient, who had good performance status, had a diagnosis of stage IVB NSCLC of adenocarcinoma histology, with a tumor positive for a KRAS G12C mutation and with 50% of tumor cells expressing PD-1.

The patient was treated with whole-brain radiation therapy and single-agent immunotherapy, and, 8 months later, in October 2021, was diagnosed with extracranial progressive disease and was then started on the KRAS G12c inhibitor sotorasib (Lumakras).

In May 2023 the patient was diagnosed with CNS oligoprogressive disease (that is, isolated progressing lesions) and underwent stereotactic radiotherapy. In June 2023 the patient was found to have progressive disease and was then started on platinum-based chemotherapy, with disease progression again noted in December of that year. The patient was still alive at the time of the presentation.

The first decision point in this case, Dr. Hendriks said, was whether to treat the patient at the time of diagnosis of brain metastases with upfront systemic or local therapy for the metastases.

At the time of extracranial progressive disease, should the treatment be another immumotherapy, chemotherapy, or a targeted agent?

“And the last decision is what should we do [in the event of] CNS oligoprogression?,” she said.
 

First Decision

For cases such as that described by Dr. Hendriks the question is whether upfront local therapy is needed if the patient is initially asymptomatic. Other considerations concerning early local therapy include the risks for late toxicities and whether there is also extracranial disease that needs to be controlled.

If systemic therapy is considered at this point, clinicians need to consider intracranial response rates to specific agents, time to onset of response, risk of pseudoprogression, and the risk of toxicity if radiotherapy is delayed until later in the disease course.

“I think all of these patients with brain metastases really deserve multidisciplinary team decisions in order to maintain or to [move] to new treatments, improve the quality of life, and improve survival,” she said.

In the case described here, the patient had small but numerous metastases that indicated the need for extracranial control, she said.

European Society of Medical Oncology (ESMO) guidelines recommend that asymptomatic patients or those with oligosymptomatic NSCLC brain metastases with an oncogenic driver receive a brain-penetrating TKI. Those with no oncogenic drive but high PD-1 expression should receive upfront immunotherapy alone, while those with PD-1 ligand 1 (PD-L1) expression below 50% receive chemoimmunotherapy.

The joint American Society of Clinical Oncology (ASCO), Society for Neuro-Oncology (SNO), and American Society for Radiation Oncology (ASTRO) guideline for treatment of brain metastases recommends a CNS-penetrating TKI for patients with asymptomatic NSCLC brain metastases bearing EGFR or ALK alterations. If there is no oncogenic driver, the guideline recommends the option of pembrolizumab (Keytruda) with or without chemotherapy.

Both the US and European guidelines recommend initiating local treatment for patients with symptomatic metastases. The level of evidence for these recommendations is low, however.

Clinicians still need better evidence about the potential for upfront immunotherapy for these patients, more information about the NSCLC brain metastases immune environment and tumor microenvironment, data on the best treatment sequence, and new strategies for improving CNS penetration of systemic therapy, Dr. Hendriks said.
 

Second Decision

At the time of CNS progression, the question becomes whether patients would benefit from targeted therapy or chemotherapy.

“We quite often say that chemotherapy doesn’t work in the brain, but that’s not entirely true,” Dr. Hendriks said, noting that, depending on the regimen range, brain response rates range from 23% to as high as 50% in patients with previously untreated asymptomatic brain metastases, although the median survival times are fairly low, on the order of 4 to almost 13 months.

There is also preclinical evidence that chemotherapy uptake is higher for larger brain metastases, compared with normal tissue and cerebrospinal fluid, “so the blood-brain barrier opens if you have the larger brain metastases,” she said.

KRAS-positive NSCLC is associated with a high risk for brain metastases, and these metastases share the same mutation as the primary cancer, suggesting potential efficacy of KRAS G12c inhibitors. There is preclinical evidence that adagrasib (Krazati) has CNS penetration, and there was evidence for intracranial efficacy of the drug in the KRYSTAL-1b trial, Dr. Hendriks noted.

There are fewer data for the other Food and Drug Administration (FDA)–approved inhibitor, sotorasib, but there is evidence to suggest that its brain activity is restricted by ABCB1, a gene encoding for a transporter protein that shuttles substances out of cells.
