SEATTLE – The American Association of Clinical Endocrinology (AACE) has released a new consensus statement aimed at helping clinicians reduce stigma and bias around obesity.

Highlights from the statement, entitled “Addressing stigma and bias in the diagnosis and management of patients with obesity/adiposity-based chronic disease and assessing bias and stigmatization as determinants of disease severity,” were presented at the annual scientific & clinical congress of the American Association of Clinical Endocrinology. It will be published later this year in Endocrine Practice.

The document reiterates AACE’s previous proposal to use the term “adiposity-based chronic disease (ABCD)” to refer to the spectrum of complications of obesity beyond weight. AACE has incorporated weight bias, stigmatization, psychological health, and social determinants of health into disease staging based on the degree to which these factors impair quality of life and could negatively affect treatment. Another change is the use of a scale from 1 to 3 for ABCD staging, in contrast to the previous scale from 0 to 3, as follows.

Stage 1 (previously 0): No known physical ABCD complications (for example, cardiovascular, biomechanical) but with increased risk that might be reduced by weight loss, and/or internalized weight bias and stigmatization, psychological conditions, and social determinants of health that don’t have immediate adverse health effects but may require individualized care.

Stage 2 (previously 1): One or more mild-moderate ABCD complications plus increased risk of other complications and/or bias/stigma/social determinants that adversely affect quality of life or could impair ABCD treatment.

Stage 3 (previously 2): At least one severe ABCD complication plus increased risk for others, and/or bias/stigma/social determinants with pronounced adverse effects on quality of life or that interfere with weight loss treatment plans or render them harmful.

To accomplish this staging, clinicians are advised to use validated questionnaires to screen patients for the presence and degree of self-stigmatization and internalized weight bias and to refer patients to mental health professionals for related psychological issues. The document also advises clinicians to implement practice policies such as implicit bias training and obesity education for their staff.  

“I really hope that this document will increase awareness of the vicious cycle of weight bias, stigma, and internalized weight bias for patients with obesity, both on an individual basis and a bigger chronic care model basis ... By utilizing these concepts in the document, we hope to at least take steps towards reducing the stigma and internalized weight bias and slowing down or reversing that vicious cycle to better care for people with a focus on their health ... It’s not just about a person’s weight,” Karl Nadolsky, DO, the statement’s co-lead author, said.

The new statement builds on previous AACE efforts, including the 2014 publication entitled, “Advanced framework for a new diagnosis of obesity as a chronic disease,” the 2016 management guidelines, and the 2016 position statement, which introduced the ABCD term. All are meant to advance the concept of obesity or ABCD as a medical condition, rather than a cosmetic problem or lifestyle choice.

Now, AACE is explicitly calling attention to the integral role of internal and external weight bias and stigma as both drivers and complications of the condition. The AACE writing panel adopted some of the concepts from a 2020 international consensus statement focusing on obesity stigma, Dr. Nadolsky said.

“We need to focus on health, the biopsychosocial mode. We have to think about the person as a whole. The disease of obesity is really a quintessential disease state that needs a very good holistic approach,” he said.

Asked to comment, Yoni Freedhoff, MD, associate professor, department of family medicine, University of Ottawa, and Medical Director of the Bariatric Medical Institute, said: “I do think staging/categorization are important in the context of bias and stigma and also to combat the notion that the goal is simple medicalization ... It’s good to see the consideration of internalized weight bias as part of an effort to understand the impact of obesity on an individual.”

However, Dr. Freedhoff said he would have preferred that the implicit and internalized bias concepts had been incorporated into the 2009 Edmonton Obesity Staging System, which he believes is easier to use than the AACE staging system.

Dr. Freedhoff also disagrees that it was necessary to remove “0” from the staging (still present in the Edmonton system), done by AACE out of concern that people might mistakenly think it implies zero risk. “It just means no current objective or subjective impact of weight on health or quality of life,” he said.

But, Dr. Nadolsky noted that data on people with “metabolically healthy obesity” suggest that “they might have zero complications but they’re still at high risk, from cancer to stigma and bias, which are a cause of and consequence of obesity and should be part of the ABCD staging system.”

Indeed, Dr. Freedhoff noted, “Obesity confers risk. Just like hypertension. And just like with hypertension, risk is not a guarantee of problems. But we still discuss treatment and people can be symptom- or problem-free when we start it. It can also be ‘borderline’ or mild. But no one gets upset about the idea of treating a known risk factor, or diagnosing a known risk factor, when minor, and when it’s not had any impact on a person’s health. That we don’t do same with obesity is consequent to bias.”

In addition to influencing health care providers and health care systems, the statement also concludes: “Society, including payers and policymakers, should support policies, education, research, and access to care to limit bias and stigma faced by individuals with obesity/ABCD.”

Dr. Nadolsky has reported no relevant financial relationships. Dr. Freedhoff has reported working with the Bariatric Medical Institute and Constant Health, which has received a research grant from Novo Nordisk.

It’s not uncommon for a medical student to change specialty plans. For Jamie Harris, a second-year student at the University of Florida School of Medicine, Gainesville, that decision came as the result of a vicious dog and an empathetic doctor.

Ms. Harris intended to become a pediatrician but is now pursuing pediatric dermatology instead.

After an attack by a dog in which she suffered extreme scarring, Ms. Harris was treated by Dhaval Bhanusali, MD, a New York dermatologist whose approach involves early and aggressive treatment. After treating her, Dr. Bhanusali offered to have Ms. Harris shadow him.

She returned to school to shadow other dermatologists and to research the specialty before taking Dr. Bhanusali up on his offer. Ms. Harris sat in on procedures and meetings with patients and studied Dr. Bhanusali’s approach to the specialty. “I just fell in love with dermatology,” Ms. Harris told this news organization. “I knew that what I wanted for my own career was exactly how he runs his practice and how he treats patients.”

Life-changing injury

In 2020, Ms. Harris was a sophomore in the University of Florida’s medical honors program, an accelerated track that allows students to earn both a bachelor of science degree and a doctor of medicine degree in 7 years. She had finished studying at a friend’s apartment and was watching television when the rescue dog the friend adopted lunged at Ms. Harris, biting her on the face. “I was just cowering in the corner of the couch,” she recalls. “I didn’t go into fight-or-flight mode; I just went into hide mode.”

After receiving stitches in the emergency department, she visited several dermatologists and plastic surgeons for further treatment. There was scarring from her forehead to her chin, which was particularly severe on her upper cheek just under her eye. But because there was no infection or medical problems, the doctors turned her away. “They said, ‘OK, you look great.’ I did not look great,” she said.

Ms. Harris’ doctors advised her to wait a year before starting treatment for the scarring, a traditional approach. She was frustrated. “At the time, I was interested in becoming a pediatrician and thought, ‘No kid is going to want me as their doctor.’ ” But she accepted the medical advice – until her mother remembered a news story she’d seen.

Bridger Walker, a 6-year-old Wyoming boy, made headlines when he saved his younger sister from a dog that was attacking, but he was bitten multiple times as a result. Dr. Bhanusali treated the boy’s scarring.

Ms. Harris and her mother contacted the doctor, and after meeting via Zoom, Dr. Bhanusali agreed to treat her right away. He used lasers to resurface the skin, which created a suitable foundation for the scar cream, and he administered steroid injections to soften the scar tissue.
 

‘I see you’

Dr. Bhansali said he was impressed with the young student he treated. “There’s curiosity, and then there’s genuine passion. She has the latter,” he said in an interview. “Having gone through this, she will understand the value of research and keeping up with the literature and that just because something is being done a certain way today doesn’t mean it has to be that way tomorrow.”

Ms. Harris agrees that the experience will make her a better dermatologist. “One of the best parts about dermatology is that you can see your results in real time and really see what’s working and what’s not working. The potential for innovation is just amazing.”

But Ms. Harris believes she also gained empathy with dermatology patients. “I know exactly what it’s like to look in the mirror and not even recognize yourself, just have your eyes go straight to one thing and feel like the whole world is staring at you,” she said. “I’ll be able to reassure people that no matter what their concern is, whether it’s eczema or acne, whether it’s one pimple, I see you, and I know exactly how that feels.”

SEATTLE – Radiofrequency ablation (RFA) appears safe and effective for the treatment of low-risk papillary thyroid microcarcinoma (PTMC), new data suggest.

RFA is increasingly gaining favor as a less-invasive alternative to surgery for patients with large, symptomatic, benign thyroid nodules in the United States and elsewhere and for the treatment of thyroid microcarcinomas in other countries, particularly South Korea and China.

Now, new findings from eight patients seen at the Mayo Clinic are the first to be reported for use of RFA for PTMC in the United States, Kharisa Rachmasari, MD, an endocrinology fellow at Mayo, said at the annual scientific & clinical congress of the American Association of Clinical Endocrinology.

Papillary thyroid cancers of 10 mm or less are the most common thyroid cancers, and their incidence is rising. They are commonly discovered incidentally in the setting of increased cross-sectional imaging. These tiny cancers are typically indolent, and they are associated with an excellent prognosis. In the United States, standard management is either surveillance or surgery, whereas RFA has been used in Europe and Asia for more than a decade, Dr. Rachmasari said.

“There has been some hesitancy when it comes to cancer, because there’s no guarantee that we can do it in such a clean way as is done with surgery, where you can actually confirm a negative margin in pathology. And the follow-up is easier as well. With RFA, the PTMC is still there, and you can only follow it with ultrasound, not biochemically with thyroglobulin or certain biomarkers,” she said in an interview.

Nonetheless, for these eight patients who underwent the procedure at Mayo’s ablation clinic, where interventional radiologists team up with endocrinologists, there were no serious adverse events, and no further interventions were required during 24 months of follow-up, she reported.

Asked to comment, session moderator Anupam Kotwal, MD, assistant professor in the division of diabetes, endocrinology and metabolism at the University of Nebraska, Omaha, said, “It’s very novel. We talk about balancing the comorbidities that come from treatment of thyroid cancer, but at the same time we want to treat it appropriately ... And of course, there are patient factors. Some may prefer to have the cancer completely out, while others are okay with watching and are against any cuts in their neck. This comes as kind of a middle ground.”

But, Dr. Kotwal added, “[Investigators] definitely need to do a bit more work, especially in the population that may be at higher risk of cancer spread, such as those with a family history of thyroid cancer. We still don’t know how autoimmune disease influences cancer progression.”

He said that if RFA is to be used for PTMC, “I think it has to be done at a center that specializes in multidisciplinary care of thyroid cancers where there are not only the experts in doing the RFA procedure but also surgical expertise, in case a complication does happen, like a vocal cord injury. Or if the cancer is growing, they can expedite getting the person that appropriate treatment.”
 

An alternative to waiting vs. surgery?

The eight patients were seen at Mayo Clinic between July 2020 and February 2023. All had papillary thyroid carcinoma that was confirmed cytologically via fine-needle biopsy and single lesions without lymph node metastasis. All patients had been offered RFA as an alternative to either surgery or active surveillance.

Seven patients were female, and one was male (mean age, 53 years). All were euthyroid at baseline, and two were receiving thyroid hormone therapy. The mean diameter of their nodules was 9.5 mm, and the mean volume was 0.3 mL.

For the first six patients, the procedure was conducted under general anesthesia; deep sedation was used for the next patient, and moderate sedation was used for the most recent. “As we learn more and gain more experience, patients nowadays have moderate sedation,” she explained.

The active tip size was 10 mm for five patients and 7 mm with three. The radiofrequency power that was delivered ranged from 25 to 45 watts. The median ablation duration was 6 minutes and ranged from 2 to 14.5. “Patients usually stay in the suite about half an hour, so it’s a quick procedure, and the patient can go home on the same day,” Dr. Rachmasari said.

Following the procedure, the ablated area increased in size during the first 3-6 months because the ablation was applied beyond the cancer margins in an attempt to ensure a negative margin, as is done surgically. By 18 months, the ablated area had shrunk and resolved.

All patients remained euthyroid in 18-24 months’ follow-up, none had any cervical adenopathy, and none required subsequent intervention.

No significant adverse events were observed during or after the RFA procedure. A few patients complained of erythema and soreness around the area of the procedure, but this resolved with over-the-counter analgesia.

Longer follow-up will be necessary to detect any recurrence, Dr. Rachmasari noted.

Dr. Kotwal pointed out that lack of reimbursement for RFA has contributed to the slow adoption of RFA overall for the treatment of thyroid nodules in the United States, but added, “I think that will change quickly, especially with more and more data coming out about large benign nodules ... I think at least from the benign nodule standpoint, with discussions happening at national meetings and societies, it should push the payers to cover.”

Overall, he said, “If you have a complication or it affects quality of life, all of those things add to the cost. So if you can use a procedure early on to prevent increasing size of either the big nodule or reduce the size of a big nodule, or even a small cancer, and give that person months or years, even if they ultimately need surgery, I think that’s still a benefit for their quality of life. But again, we have to take patient factors into account.”

Dr. Rachmasari and Dr. Kotwal have disclosed no relevant financial relationships.

Now, new findings from eight patients seen at the Mayo Clinic are the first to be reported for use of RFA for PTMC in the United States, Kharisa Rachmasari, MD, an endocrinology fellow at Mayo, said at the annual scientific & clinical congress of the American Association of Clinical Endocrinology.

Papillary thyroid cancers of 10 mm or less are the most common thyroid cancers, and their incidence is rising. They are commonly discovered incidentally in the setting of increased cross-sectional imaging. These tiny cancers are typically indolent, and they are associated with an excellent prognosis. In the United States, standard management is either surveillance or surgery, whereas RFA has been used in Europe and Asia for more than a decade, Dr. Rachmasari said.

“There has been some hesitancy when it comes to cancer, because there’s no guarantee that we can do it in such a clean way as is done with surgery, where you can actually confirm a negative margin in pathology. And the follow-up is easier as well. With RFA, the PTMC is still there, and you can only follow it with ultrasound, not biochemically with thyroglobulin or certain biomarkers,” she said in an interview.

Nonetheless, for these eight patients who underwent the procedure at Mayo’s ablation clinic, where interventional radiologists team up with endocrinologists, there were no serious adverse events, and no further interventions were required during 24 months of follow-up, she reported.

Asked to comment, session moderator Anupam Kotwal, MD, assistant professor in the division of diabetes, endocrinology and metabolism at the University of Nebraska, Omaha, said, “It’s very novel. We talk about balancing the comorbidities that come from treatment of thyroid cancer, but at the same time we want to treat it appropriately ... And of course, there are patient factors. Some may prefer to have the cancer completely out, while others are okay with watching and are against any cuts in their neck. This comes as kind of a middle ground.”

But, Dr. Kotwal added, “[Investigators] definitely need to do a bit more work, especially in the population that may be at higher risk of cancer spread, such as those with a family history of thyroid cancer. We still don’t know how autoimmune disease influences cancer progression.”

He said that if RFA is to be used for PTMC, “I think it has to be done at a center that specializes in multidisciplinary care of thyroid cancers where there are not only the experts in doing the RFA procedure but also surgical expertise, in case a complication does happen, like a vocal cord injury. Or if the cancer is growing, they can expedite getting the person that appropriate treatment.”
 

An alternative to waiting vs. surgery?

The eight patients were seen at Mayo Clinic between July 2020 and February 2023. All had papillary thyroid carcinoma that was confirmed cytologically via fine-needle biopsy and single lesions without lymph node metastasis. All patients had been offered RFA as an alternative to either surgery or active surveillance.

Seven patients were female, and one was male (mean age, 53 years). All were euthyroid at baseline, and two were receiving thyroid hormone therapy. The mean diameter of their nodules was 9.5 mm, and the mean volume was 0.3 mL.

For the first six patients, the procedure was conducted under general anesthesia; deep sedation was used for the next patient, and moderate sedation was used for the most recent. “As we learn more and gain more experience, patients nowadays have moderate sedation,” she explained.

The active tip size was 10 mm for five patients and 7 mm with three. The radiofrequency power that was delivered ranged from 25 to 45 watts. The median ablation duration was 6 minutes and ranged from 2 to 14.5. “Patients usually stay in the suite about half an hour, so it’s a quick procedure, and the patient can go home on the same day,” Dr. Rachmasari said.

Following the procedure, the ablated area increased in size during the first 3-6 months because the ablation was applied beyond the cancer margins in an attempt to ensure a negative margin, as is done surgically. By 18 months, the ablated area had shrunk and resolved.

All patients remained euthyroid in 18-24 months’ follow-up, none had any cervical adenopathy, and none required subsequent intervention.

No significant adverse events were observed during or after the RFA procedure. A few patients complained of erythema and soreness around the area of the procedure, but this resolved with over-the-counter analgesia.

Longer follow-up will be necessary to detect any recurrence, Dr. Rachmasari noted.

Dr. Kotwal pointed out that lack of reimbursement for RFA has contributed to the slow adoption of RFA overall for the treatment of thyroid nodules in the United States, but added, “I think that will change quickly, especially with more and more data coming out about large benign nodules ... I think at least from the benign nodule standpoint, with discussions happening at national meetings and societies, it should push the payers to cover.”

Overall, he said, “If you have a complication or it affects quality of life, all of those things add to the cost. So if you can use a procedure early on to prevent increasing size of either the big nodule or reduce the size of a big nodule, or even a small cancer, and give that person months or years, even if they ultimately need surgery, I think that’s still a benefit for their quality of life. But again, we have to take patient factors into account.”

Dr. Rachmasari and Dr. Kotwal have disclosed no relevant financial relationships.

BOSTON – Having a preoperative MRI scan does not help surgeons to reduce the likelihood of positive surgical margins when they are performing lumpectomy for early stage breast cancer, a new study concludes.

The current results suggest that MRI is “not useful to achieve this goal and not a productive use of health care resources,” said senior author Marissa Howard-McNatt, MD, director of the Breast Care Center, Wake Forest University, Winston-Salem, N.C.

“Researchers continue to look for better ways to assess margin status while the patient is still on the operating table,” she said, as a re-operation “can be traumatic.”

The study was presented at the annual meeting of the American Society of Breast Surgeons and was highlighted in a press briefing.

In the study, more than 630 patients with early stage breast cancer were randomly assigned to partial mastectomy with or without cavity shaving of the tumor margins, of whom 193 underwent MRI before their operation.

Although there was a difference in the rate of positive surgical margins before cavity shaving between patients who did and did not undergo MRI, the difference did not reach statistical significance.

“MRI exams are costly and potentially stressful for patients,” Dr. Howard-McNatt commented in a press statement. “The thought is that they will help physicians achieve negative margins during the initial surgery. However, our study shows this is simply not the case.”

Approached for comment, Mediget Teshome, MD, MPH, said, “In my practice, I primarily utilize MRI preoperatively to evaluate the extent of disease in cases where the information is not clear from mammogram and ultrasound.”

This may be when there is “discordance between the size of the malignancy or concern for chest wall or muscle involvement,” Dr. Teshome said in an interview.

MRI is also useful when there may be occult disease, such as in patients “with high suspicion for extensive intraductal component not evident on mammography and those who present with axillary metastasis and unknown breast primary,” as well as in high-risk patients with a genetic predisposition for breast cancer, she explained.

However, Dr. Teshome, an associate professor in the department of breast surgical oncology at the University of Texas MD Anderson Cancer Center, Houston, stressed that, “as with any test, it is important that preoperative MRI is performed with the specific intent to inform clinical decision-making in a meaningful way.”

“While it can provide a benefit in selected cases given its high sensitivity, MRI is associated with false positives and can also contribute to increased patient anxiety and additional procedures,” she cautioned.
 

Study details

Lumpectomy has become “a mainstay of breast cancer management, with safe and reliable outcomes as compared to mastectomy,” said Dr. Howard-McNatt, but it is associated with a higher rate of positive margins, of up to 27%.

She underlined that “re-excision surgery can contribute to greater morbidity, patient anxiety, poor cosmetic outcomes, and health care system overload,” and the desire to reduce re-operations has led to “much attention” being paid to preoperative imaging.

Their study set out to investigate the value of preoperative MRI in this regard, and for this they analyzed data on 631 women who had participated in two prior randomized trials (SHAVE1 and SHAVE2).

These women were randomly assigned to standard partial mastectomy with or without resection of cavity shave margins, with preoperative MRI performed prior to randomization in both trials at the surgeon’s discretion.

The median tumor size was 1.3 cm. An extensive intraductal component was identified in 32.8% of patients, 26.1% had palpable tumors, and 7% had invasive lobular histology. Neoadjuvant chemotherapy was administered in 6.5% of patients.

In all, 193 individuals underwent MRI. These women were less likely to have a positive surgical margin before resection of cavity shave margins, at 31.1% vs. 38.8% in those who did not have MRI, although the difference was not statistically significant (P = .073).

Multivariate analysis taking into account patient age, race, receipt of neoadjuvant chemotherapy, the presence of an extensive intraductal component, as well as histologic subtype and tumor size, revealed that MRI was not associated with a higher rate of negative surgical margins (P = .110).

However, it was shown that both tumor size (P = .040) and age (P = .032) were predictive of margin status.

It was notable that MRI use was associated with younger patient age, at a median of 63 years vs. 66 years, and smaller tumor size, at a median of 2.0 cm vs. 2.1 cm.

This latter finding “may be attributable to an inaccurate initial assessment of the extent of the actual tumor size for a variety of reasons,” Dr. Howard-McNatt commented. “For example, tumors may be discontinuous or have satellite lesions which may touch the edge of a specimen.”

The study was funded in part by the David and Katie Burke Fund for Breast Cancer Research, the Connecticut Breast Health Initiative, the Troy Cancer Program, Cleveland Clinic Akron General Operations, the Cleveland Clinic Akron General Foundation, the Lineberger Comprehensive Cancer Center, the Watson Clinic Center for Research, and LifeCycle. The study authors report no relevant financial relationships.

BOSTON – Older women who have had breast cancer frequently undergo annual surveillance mammography, even if there is only a small risk of their developing a second cancer or if they have other mortality risks associated with age and comorbidities. This ongoing annual surveillance with mammography may be doing more harm than good, warn researchers.

In a study that included almost 45,000 women who were aged 67 years or older when they were diagnosed with breast cancer, investigators found that patients commonly underwent annual mammographies.

“Even 10 years after their initial diagnosis ... about 40% of them were still getting surveillance mammography well into their 80s and 90s,” noted lead investigator Elizabeth Berger, MD, assistant professor of breast surgical oncology, Yale University, New Haven, Conn.

“Ongoing surveillance mammography in these patients may lead to overdiagnosis and overtreatment of cancers that potentially would not harm patients if left untreated,” Dr. Berger said.

“A positive or false positive finding may unnecessarily erode patient quality of life and incur costs to the patient and health care system without benefit,” she said. She added: “If an elderly woman is in poor health and has significant competing mortality risks compared to breast cancer, annual mammography may not be necessary.”

The research was presented at the annual meeting of the American Society of Breast Surgeons (ASBrS). The study was highlighted in a preview press briefing.

Speaking at the press briefing, Dr. Berger said that the “risks and benefits of surveillance mammography, including its downstream effects, should be considered by both patients and their doctors together to create a shared decision plan.” She acknowledged that the idea of skipping mammograms may be a sensitive one for patients.

She also shared what she described as “exciting news”: “We have just recently received funding from our geriatric group here at Yale to start to evaluate the potential benefits and harms of these surveillance mammographies.”

The aim is to evaluate false positive rates and the potential for overdiagnosis and overtreatment, “so stay tuned,” she added.

Approached for comment, Mediget Teshome, MD, MPH, said it was “not surprising to see the high rates of surveillance mammography, especially in the short term after treatment.”

She said in an interview that the results suggest that it “may be being overused,” given the low rates of second primary breast cancer and the “competing health concerns” of these women.

Overuse can, on the other hand, “definitely be a complex issue,” said Dr. Teshome, associate professor, department of breast surgical oncology, University of Texas MD Anderson Cancer Center, Houston.

“The goal of mammography screening is to identify breast cancer at an early stage,” she explained. She noted that because of the “competing mortality risk from other challenging and life-threatening health problems,” early-stage breast cancer “may not contribute significantly” to the overall mortality risk.

“In general, in this patient population, consideration should be given to stratifying based on an individual patient’s risk of breast cancer recurrence or new breast cancer, estimated life expectancy, as well as shared decision-making with the patient based on their goals of care.”
 

Study details

To examine the use of surveillance mammography and the risk of subsequent cancers among older women, Dr. Berger and her team used data from the Surveillance, Epidemiology, and End Results (SEER) registry to identify women aged 67 years or older who were diagnosed with a first nonmetastatic beast cancer between 2003 and 2007.

The patients were followed beginning 1 year after diagnosis until the occurrence of a second primary breast cancer, death, or the end of follow-up in 2017.

Data on 44,475 women were analyzed. Of those patients, 30% were older than 80 years. The majority (74%) of breast cancers were of stage I or II, and 72% were hormone receptor–positive (HR+).

Comorbid conditions were common; 55% of women had at least one, and 16% had three or more.

Life expectancy, determined on the basis of age, sex, and comorbidities, was estimated at less than 5 years for 26% of women. For 36% of patients, life expectancy was 6-10 years, and for 38%, it was longer than 10 years.

The cumulative incidence of developing a second primary breast cancer varied by life expectancy and the tumor’s molecular subtype.

The incidence was 3.7% among women with a life expectancy of less than 5 years, 4.9% among those expected to live 6-10 years, and 7.6% among those predicted to live more than 10 years.

Among women with a life expectancy of less than 5 years, the cumulative incidence of a second primary tumor was 4.0% among those with triple-negative breast cancer, vs. 3.0% among those with HR+ breast cancer.

Among patients whose life expectancy was more than 10 years, the cumulative incidence of a second primary tumor was 9.2% among women with triple-negative disease, vs. 7.0% among those with HR+ cancers.

The team found that it was common for women across all the groups to undergo mammography.

Among women with a life expectancy of 6-10 years, 82% underwent at least one mammogram, and 65% underwent five mammograms. Even among women with a life expectancy of less than 1 year, 51% underwent at least one mammogram within 12 months of death.

Among women with a life expectancy of less than 5 years, 68% of women had received a mammogram 1 year after treatment; 53% underwent three mammograms within 3 years after treatment.

No funding for the study was declared. The investigators have disclosed no relevant financial relationships.

She noted that because of the “competing mortality risk from other challenging and life-threatening health problems,” early-stage breast cancer “may not contribute significantly” to the overall mortality risk.

“In general, in this patient population, consideration should be given to stratifying based on an individual patient’s risk of breast cancer recurrence or new breast cancer, estimated life expectancy, as well as shared decision-making with the patient based on their goals of care.”
 

Study details

To examine the use of surveillance mammography and the risk of subsequent cancers among older women, Dr. Berger and her team used data from the Surveillance, Epidemiology, and End Results (SEER) registry to identify women aged 67 years or older who were diagnosed with a first nonmetastatic beast cancer between 2003 and 2007.

The patients were followed beginning 1 year after diagnosis until the occurrence of a second primary breast cancer, death, or the end of follow-up in 2017.

Data on 44,475 women were analyzed. Of those patients, 30% were older than 80 years. The majority (74%) of breast cancers were of stage I or II, and 72% were hormone receptor–positive (HR+).

Comorbid conditions were common; 55% of women had at least one, and 16% had three or more.

Life expectancy, determined on the basis of age, sex, and comorbidities, was estimated at less than 5 years for 26% of women. For 36% of patients, life expectancy was 6-10 years, and for 38%, it was longer than 10 years.

The cumulative incidence of developing a second primary breast cancer varied by life expectancy and the tumor’s molecular subtype.

The incidence was 3.7% among women with a life expectancy of less than 5 years, 4.9% among those expected to live 6-10 years, and 7.6% among those predicted to live more than 10 years.

Among women with a life expectancy of less than 5 years, the cumulative incidence of a second primary tumor was 4.0% among those with triple-negative breast cancer, vs. 3.0% among those with HR+ breast cancer.

Among patients whose life expectancy was more than 10 years, the cumulative incidence of a second primary tumor was 9.2% among women with triple-negative disease, vs. 7.0% among those with HR+ cancers.

The team found that it was common for women across all the groups to undergo mammography.

Among women with a life expectancy of 6-10 years, 82% underwent at least one mammogram, and 65% underwent five mammograms. Even among women with a life expectancy of less than 1 year, 51% underwent at least one mammogram within 12 months of death.

Among women with a life expectancy of less than 5 years, 68% of women had received a mammogram 1 year after treatment; 53% underwent three mammograms within 3 years after treatment.

No funding for the study was declared. The investigators have disclosed no relevant financial relationships.

BOSTON – Older women who have had breast cancer frequently undergo annual surveillance mammography, even if there is only a small risk of their developing a second cancer or if they have other mortality risks associated with age and comorbidities. This ongoing annual surveillance with mammography may be doing more harm than good, warn researchers.

In a study that included almost 45,000 women who were aged 67 years or older when they were diagnosed with breast cancer, investigators found that patients commonly underwent annual mammographies.

“Even 10 years after their initial diagnosis ... about 40% of them were still getting surveillance mammography well into their 80s and 90s,” noted lead investigator Elizabeth Berger, MD, assistant professor of breast surgical oncology, Yale University, New Haven, Conn.

“Ongoing surveillance mammography in these patients may lead to overdiagnosis and overtreatment of cancers that potentially would not harm patients if left untreated,” Dr. Berger said.

“A positive or false positive finding may unnecessarily erode patient quality of life and incur costs to the patient and health care system without benefit,” she said. She added: “If an elderly woman is in poor health and has significant competing mortality risks compared to breast cancer, annual mammography may not be necessary.”

The research was presented at the annual meeting of the American Society of Breast Surgeons (ASBrS). The study was highlighted in a preview press briefing.

Speaking at the press briefing, Dr. Berger said that the “risks and benefits of surveillance mammography, including its downstream effects, should be considered by both patients and their doctors together to create a shared decision plan.” She acknowledged that the idea of skipping mammograms may be a sensitive one for patients.

She also shared what she described as “exciting news”: “We have just recently received funding from our geriatric group here at Yale to start to evaluate the potential benefits and harms of these surveillance mammographies.”

The aim is to evaluate false positive rates and the potential for overdiagnosis and overtreatment, “so stay tuned,” she added.

Approached for comment, Mediget Teshome, MD, MPH, said it was “not surprising to see the high rates of surveillance mammography, especially in the short term after treatment.”

She said in an interview that the results suggest that it “may be being overused,” given the low rates of second primary breast cancer and the “competing health concerns” of these women.

Overuse can, on the other hand, “definitely be a complex issue,” said Dr. Teshome, associate professor, department of breast surgical oncology, University of Texas MD Anderson Cancer Center, Houston.

SAN DIEGO – Gout is one of the most poorly managed diseases and is mostly treated by primary care providers, said a presenter at the annual meeting of the American College of Physicians. Failure to understand the disease process and goals of urate-lowering therapy (ULT) is a key barrier to achieving optimal gout therapy.

“There’s too much focus on the flare and too little focus on the urate burden of the disease. Regardless of the clinical setting, the goal should be to manage [high] serum uric acid levels,” said Lawrence Edwards, MD, professor at the University of Florida, Gainesville, during his talk.

Dr. Edwards, who specializes in treating patients with gout and rheumatoid arthritis, discussed the role of primary care providers in the treatment of gout. “We can and must do better,” he said.
 

Understanding the pathology of gout is key to effective treatment

Knowledge of the molecular pathology of gout has advanced drastically over the last few years. “The improved understanding of the molecules involved in disease initiation and progression can help us make better treatment decisions depending on the stage of the disease,” Dr. Edwards said.

Gout is caused by the deposition of monosodium urate (MSU) crystals, which starts as asymptomatic hyperuricemia, he said. Inflammatory responses to MSU crystals are responsible for gout flares, the frequency of which increases as the disease progresses.

Innate immune responses driven by macrophages and neutrophils play a crucial role in acute gout attacks. In the molecular pathway, proinflammatory cytokines IL-1 beta and IL-6 are the mediators of gout flares, whereas IL-8 accumulates over time and contributes to disease progression and systemic illness. If left untreated or undertreated, the repeated inflammatory reaction leads to advanced gout. The urate burden also increases with disease progression.

“Physicians need to better educate themselves on the destructive nature of this inflammatory arthritis and the need for effective urate-lowering therapy in the management of gout,” Dr. Edwards said.
 

Management of acute gout attacks

The management of gout flares involves the use of pharmacological agents to control pain and inflammation. The three most common anti-inflammatory therapies are colchicine, NSAIDs, and corticosteroids (either oral or intramuscular).

The choice of which of these should be used alone or in combination for a flare is based on previous tolerance of the medication or the presence of diabetes, kidney disease, heart disease, or a history of upper gastrointestinal bleeding. Dr. Edwards referred internists to the 2020 American College of Rheumatology gout management guideline.

“Regardless of which therapy is chosen, the more important consideration is how quickly the patients can start treatment after the flare begins,” said Dr. Edwards when asked about priorities in the management of gout flares. “This means that the patient should have ready access to whichever the chosen approach is. We call this the ‘pill-in-the-pocket’ approach,” he added.

Reducing the urate burden is also important for effective treatment. The serum urate level is the primary marker of how well a patient’s gout is being managed. ULT should be initiated in patients with subcutaneous tophi, gout-related radiographic damage, or frequent flares (≥ 2 per year). Allopurinol is typically the first-line ULT of choice.

Dr. Edwards noted that far too much focus is placed on flare treatment rather than addressing the underlying sources of gouty symptoms – the elevated serum levels of urate.
 

Management of advanced gout

“The management of advanced gout is challenging, and the dissolution of MSU is slow unless you take an aggressive approach,” Dr. Edwards said.

Switching to pegloticase is recommended for patients with frequent flares, nonresolving tophi, or high serum urate levels that persist despite treatment with xanthine oxidase inhibitors or other ULT agents.

“The frequency and severity of gout flares are what patients focus on, but if that’s the only focus of the treating physicians, then they are leaving the job less than halfway done. Getting the serum urate to below a level of 6.0 mg/dL is the most important aspect in the lifelong management of gout,” said Dr. Edwards.
 

Barriers to effective gout treatment

When asked during an interview after the session about the most important barriers to successful gout management, Allison M. Mays, MD, a geriatric medicine subspecialist at Cedars-Sinai Medical Center, Los Angeles, said that “the fact that gout mostly impacts quality of life and not necessarily mortality means that other things may take precedent.” She explained that gout typically coexists with other comorbidities, often multiple ones. Patients may also defer taking an additional medication for a disease like gout, which has only episodic discomfort.

She added that gout management involves shared decision-making between patients and the medical team – including the primary care physician, rheumatologist, orthopedist, and emergency physician. Following a visit to the urgent care or the ED for an acute flare of gout, the patient may not follow up with their primary care doctor or bring it up at their next visit for chronic management, she noted.

Dr. Edwards serves as a consultant to Horizon Pharmaceuticals, Atom Biosciences, Shanton Biosciences, and Aclaris Therapeutics. Horizon marketed pegloticase up until last month when Amgen bought the drug. Dr. Edwards is also president of Gout Education Society, and he has no financial agreement with any of the multiple companies that produce colchicine and allopurinol. Dr. Mays reported no conflicts.

The Food and Drug Administration has acknowledged reports of squamous cell carcinoma (SCC) of the breast as well as lymphomas associated with postmastectomy breast implants.

Findings from a large cohort study suggest the incidence of SCC is negligible. The analysis found one case of SCC among nearly 57,000 women who had undergone breast implant reconstruction over 421,227 person-years of follow-up.

The authors also confirmed the known risk of breast implant–associated anaplastic large-cell lymphoma (ALCL), identifying five cases in the population, which was considered a “significantly elevated” risk.

Although patients with breast cancer who are eligible for mastectomy should be counseled on the risks for cancer after implant reconstruction, patients “should not be dissuaded from pursuing implant-based reconstruction because of the risk of SCC,” lead author Connor J. Kinslow, MD, of Columbia University, New York, and colleagues concluded.

SCC cases associated with breast implants are distinct from breast implant–associated ALCL, the authors noted, explaining that this lymphoma “is the subject of a boxed warning on all saline- and silicone gel–filled breast implants since 2020.” 

The results were published in a research letter in JAMA Surgery.

Last September, a safety communication from the FDA highlighted reports of SCC and other lymphomas associated with breast implants. The FDA said it was aware of fewer than 20 cases of SCC.

Following the safety communication, Dr. Kinslow and colleagues assessed SCC risk among 56,785 women who underwent cancer-directed mastectomy with implant reconstruction for breast tumors.

Women in the cohort were diagnosed between 2000 and 2018 and included in the Surveillance, Epidemiology, and End Results (SEER) 17 database. Patients had a median age of 51 years; most (84%) where White, 8.1% were Black, 7.4% were Asian or Pacific Islander, 0.4% were American Indian/Alaska Native, and race was unknown in 0.4%.

Across 421,227 person-years of follow-up, the team identified one case of SCC, corresponding to an incidence rate of 2.37 per million person-years vs. an expected incidence of 1.02 per million person-years in the general population. Although the 2.33 standardized incidence ratio (SIR) “appeared elevated vs. the general population,” it was “not significant given the low incidence” (95% confidence interval, 0.06-13.0).

The team also identified five cases of breast implant–associated ALCL. That corresponded to an incidence rate of 11.9 per million person-years compared with an expected incidence of 0.29 per million person-years – for a significantly elevated SIR of 40.9. The authors also noted more than 1,000 reported cases of breast implant–associated ALCL previous as well as a robust association with implants.

Regarding SCC, “whether the observed elevated risk is associated with the implants is difficult to interpret because it is based on only one case and wide [confidence intervals],” the authors said. But, overall, “we found that the incidence rate of SCC was extraordinarily low and of minimal public health concern.”

Investigators for a study of children with parent-reported attention deficit/hyperactivity disorder (ADHD) found that only 12.9% are receiving medications for the disorder and only 26.2% have ever received outpatient mental health care. Just more than one-third (34.8%) had received either treatment.

Researchers, led by Mark Olfson, MD, MPH, Elizabeth K. Dollard Professor of Psychiatry, Medicine and Law and professor of epidemiology at New York State Psychiatric Institute and Columbia University Department of Psychiatry, New York, also found that girls were much less likely to get medications.

Columbia University

In this cross-sectional sample taken from 11, 723 children in the Adolescent Brain and Cognitive Development Study, 1,206 children aged 9 and 10 years had parent-reported ADHD, and of those children, 15.7% of boys and 7% of girls were currently receiving ADHD medications. The parents reported the children met ADHD criteria according to the Diagnostic and Statistical Manual of Mental Disorders.

Findings were published online in JAMA Network Open.
 

Diagnoses have doubled but treatment numbers lag

Report authors noted that the percentage of U.S. children whose parents report their child has been diagnosed with ADHD has nearly doubled over 2 decades from 5.5% in 1999 to 9.8% in 2018. That has led to misperceptions among professionals and the public that the disorder is overdiagnosed and overtreated, the authors wrote.

However, they wrote, “a focus on the increasing numbers of children treated for ADHD does not give a sense of what fraction of children in the population with ADHD receive treatment.”
 

Higher uptake at lower income and education levels

Researchers also found that, contrary to popular belief, children with ADHD from families with lower educational levels and lower income were more likely than those with higher educational levels and higher incomes to have received outpatient mental health care.

Among children with ADHD whose parents did not have a high school education, 32.2% of children were receiving medications while among children of parents with a bachelor’s degree 11.5% received medications.

Among children from families with incomes of less than $25 000, 36.5% were receiving outpatient mental health care, compared with 20.1% of those from families with incomes of $75,000 or more.

“These patterns suggest that attitudinal rather than socioeconomic factors often impede the flow of children with ADHD into treatment,” they wrote.
 

Black children less likely to receive medications

The researchers found that substantially more White children (14.8% [104 of 759]) than Black children (9.4% [22 of 206]), received medication, a finding consistent with previous research.

“Population-based racial and ethnic gradients exist in prescriptions for stimulants and other controlled substances, with the highest rates in majority-White areas,” the authors wrote. “As a result of structural racism, Black parents’ perspectives might further influence ADHD management decisions through mistrust in clinicians and concerns over safety and efficacy of stimulants.”

“Physician efforts to recognize and manage their own implicit biases, together with patient-centered clinical approaches that promote shared decision-making,” might help narrow the treatment gap, the authors wrote. That includes talking with Black parents about their knowledge and beliefs concerning managing ADHD, they added.
 

Confirming diagnosis critical

The authors noted that not all children with parent-reported ADHD need treatment or would benefit from it.

Lenard Adler, MD, director of the adult ADHD program and professor of Psychiatry and Child and Adolescent Psychiatry at New York University Langone Health, who was not part of the current study, said this research emphasizes the urgency of clinical diagnosis.

Dr. Adler was part of a team of researchers that found similar low numbers for treatment among adults with ADHD.

The current results highlight that “we want to get the diagnosis correct so that people who receive a diagnosis actually have it and, if they do, that they have access to care. Because the consequences for not having treatment for ADHD are significant,” Dr. Adler said.

He urged physicians who diagnose ADHD to make follow-up part of the care plan or these treatment gaps will persist.

The authors wrote that the results suggest a need to increase availability for mental health services and better communicate symptoms among parents, teachers, and primary care providers.

The authors declare no relevant financial relationships. Dr. Adler has consulted with Supernus Pharmaceuticals and Otsuka Pharmaceuticals, has done research with Takeda, and has received royalty payments from NYU for licensing of ADHD training materials.

Investigators for a study of children with parent-reported attention deficit/hyperactivity disorder (ADHD) found that only 12.9% are receiving medications for the disorder and only 26.2% have ever received outpatient mental health care. Just more than one-third (34.8%) had received either treatment.

Researchers, led by Mark Olfson, MD, MPH, Elizabeth K. Dollard Professor of Psychiatry, Medicine and Law and professor of epidemiology at New York State Psychiatric Institute and Columbia University Department of Psychiatry, New York, also found that girls were much less likely to get medications.

In this cross-sectional sample taken from 11, 723 children in the Adolescent Brain and Cognitive Development Study, 1,206 children aged 9 and 10 years had parent-reported ADHD, and of those children, 15.7% of boys and 7% of girls were currently receiving ADHD medications. The parents reported the children met ADHD criteria according to the Diagnostic and Statistical Manual of Mental Disorders.

Findings were published online in JAMA Network Open.

Diabetes devices represent a major advancement in the management of diabetes, but they can cause skin reactions that affect patient adherence and quality of life, Jennifer K. Chen, MD, said in a presentation at the annual meeting of the American Contact Dermatitis Society.

Advanced technologies used for the management of diabetes fall into three main categories, said Dr. Chen, of the department of dermatology, Stanford University, Redwood City, Calif. Continuous glucose monitoring (CGM) devices, which are worn on the body, collect glucose measurements. Continuous subcutaneous insulin infusion (CSII) devices are attached to the body via an infusion set and are now available as tubing-free patch pumps that are attached directly to the skin via a catheter. Glucose-responsive insulin delivery systems combine the sensing and delivery features of the other two types of devices.

Dr. Chen

Once thought to be rare, reports of skin complications related to diabetes devices have been increasing in recent years, she said. Some reports suggest that at any given time, skin complications may affect as many as one quarter to one half of patients who use these devices, “so this is an important issue,” she emphasized. “Skin reactions are a major factor in device discontinuation, so we as clinicians need to be really proactive about treating these reactions.”

Risk factors for skin complications related to diabetes devices include sensitization to the adhesive used with the devices, as well as prolonged exposure to the device, Dr. Chen said. Younger age also appears to be a risk factor, as is a compromised skin barrier in the area where the device is used.

Unfortunately, obtaining details on the specific adhesives and the raw materials used in these devices, so as to customize patch testing, remains a challenge, she said. “Patch testing initially was often negative to commercially available allergens, even while patients were testing positive to pieces of device adhesive,” she noted.
 

Consider isobornyl acrylate

An article published in 2017 in Contact Dermatitis was “a major breakthrough” in that it identified isobornyl acrylate (IBOA) as an allergen in connection with the Freestyle Libre, a CGM device that was relatively new at the time. The finding was serendipitous, Dr. Chen said. A patient being treated for suspected allergic contact dermatitis in connection with use of a Freestyle Libre device was tested for IBOA accidentally, after the nurse administering the patch test thought that this was part of the standard acrylate series, she explained.

Subsequently, researchers identified 15 patients who had experienced reactions to the Freestyle Libre; 12 of 13 patients who were patch tested for IBOA tested positive. IBOA was found throughout the device, particularly where the top and bottom plastic components were connected, Dr. Chen said. This suggested that the IBOA was in the device housing and had diffused into the adhesive that attached the device to the skin.

An article published in 2018 in the Journal of Diabetes Science described three patients who developed severe allergic contact dermatitis from IBOA while using a CGM device, Dr. Chen said. The investigators confirmed that there were no reactions to the adhesive itself, again suggesting that IBOA had diffused into the adhesive from other parts of the device.

Although the authors were bound by a confidentiality agreement regarding the individual adhesive components, “the authors noted most of the acrylates in the adhesive were not present in commercially available acrylate series for patch testing,” she said.

IBOA, the ACDS’ Allergen of the Year in 2020, is common in sealants, glues, and adhesives, Dr. Chen said. Although IBOA had been reported infrequently as an allergen, it has now been identified as a “potential culprit” behind skin reactions in many diabetes devices, including CSII and CGM devices, she added.

In addition, N,N-dimethylacrylamide (DMAA) is an allergen that has been identified in several diabetes devices and often occurs with IBOA in medical-grade UV-cured adhesives, Dr. Chen noted. Other allergens identified in diabetes devices include colophony, which is present in many adhesives, as well as other acrylates and epoxy resin.

Diabetes devices are constantly evolving. IBOA is no longer found in Freestyle Libre devices. It is important that clinicians stay up to date with the medical literature and advocate for partnership with device manufacturers, she emphasized.
 

Patch testing

When diabetes devices are suspected as the source of allergic contact dermatitis, a minimum of a baseline series that contains colophony at a concentration of 20% in petrolatum should be carried out, Dr. Chen said. Commercialized patch test trays, which include plastics, glues, acrylates, epoxy resins/isocyanates, and colophony derivatives, should be ideal. “Personal-care products should be included if they are potentially relevant,” she added.

Dr. Chen shared tables published in Contact Dermatitis in 2021 with examples of screening test series. She said to consider including screening for other allergens more recently discovered in diabetes devices, including 2,2’-methylenebis(6-tert-butyl-4-methylphenol) monoacrylate (MBPA) 1.5% pet; dipropylene glycol diacrylate (DPGDA) 0.1% pet; and butylated hydroxytoluene (BHT) 2% pet.

Testing for monomethyl ether of hydroquinone should also be considered; this may be included in the test preparations for IBOA and DMAA.
 

Management strategies

For patients who experience skin reactions to their diabetes devices, consideration may given to relocating the device to another area of skin or changing sensors more frequently, according to Dr. Chen.

For some patients, the reaction can be managed with corticosteroid cream, ointment, solution, or nasal spray. Topical antibiotics or topical antihistamines can be helpful, as can barrier dressings, solutions, or sprays, she said. The best solution is to change to a device that does not have the culprit allergen, “but that is difficult, since we don’t know what is in these devices,” she added. Good alternatives include the Eversense CGM device or devices that have been demonstrated not to contain IBOA, such as the Freestyle Libre 2 or the newer version of the Omnipod, an insulin delivery system

Looking ahead, Dr. Chen said that “mandatory labeling is needed, as devices with the same name may have different compositions, depending on the date of manufacture.” Allergens relevant to people with diabetes are constantly evolving, and many are still unidentified, so clinicians and manufacturers need to work together to identify the culprit allergens and their sources, she said.

Dr. Chen has served as principal investigator or subinvestigator for Amgen, AbbVie, and Sanofi Regeneron and as a consultant for Purity Brands.

Consider popular nutritional supplements as a potential source of allergic reactions if the cause of the reaction is otherwise unknown, Alison Ehrlich, MD, said at the annual meeting of the American Contact Dermatitis Society.

Sherri Holdridge

Allergens may be hidden in a range of supplement products, from colorings in vitamin C powders to some vitamins used in hair products and other products.

“In general, our patients do not tell us what supplements they are taking,” said Dr. Ehrlich, a dermatologist who practices in Washington, D.C. Antiaging, sleep, and weight loss/weight control supplements are among the most popular, she said.

Surveys have shown that many patients do not discuss supplement use with their health care providers, in part because they believe their providers would disapprove of supplement use, and patients are not educated about supplements, she said. “This is definitely an area that we should try to learn more about,” she added.

Current regulations regarding dietary supplements stem from the Dietary Supplement Health and Education Act of 1994, which defined dietary supplements as distinct from meals but regulated them as a category of food, not as medications. Dietary supplements can be vitamins, minerals, herbs, and extracts, Dr. Ehrlich said.

“There is not a lot of safety wrapped around how supplements come onto the market,” she explained. “It is not the manufacturer’s responsibility to test these products and make sure they are safe. When they get pulled off the market, it is because safety reports are getting back to the FDA.”

Consequently, a detailed history of supplement use is important, as it may reveal possible allergens as the cause of previously unidentified reactions, she said.

Dr. Ehrlich shared a case involving a patient who claimed to have had a reaction to a “Prevage-like” product that was labeled as a crepe repair cream. Listed among the product’s ingredients was idebenone, a synthetic version of the popular antioxidant known as Coenzyme Q.
 

Be wary of vitamins

Another potential source of allergy is vitamin C supplements, which became especially popular during the pandemic as people sought additional immune system support, Dr. Ehrlich noted. “What kind of vitamin C product our patients are taking is important,” she said. For example, some vitamin C powders contain coloring agents, such as carmine. Some also contain gelatin, which may cause an allergic reaction in individuals with alpha-gal syndrome, she added.

In general, water-soluble vitamins such as vitamins B1 to B9, B12, and C are more likely to cause an immediate reaction, Dr. Ehrlich said. Fat-soluble vitamins, such as vitamins A, D, E, and K, are more likely to cause a delayed reaction of allergic contact dermatitis.

Dr. Ehrlich described some unusual reactions to vitamins that have been reported, including a systemic allergy associated with vitamin B1 (thiamine), burning mouth syndrome associated with vitamin B3 (nicotinate), contact urticaria associated with vitamin B5 (panthenol), systemic allergy and generalized ACD associated with vitamin E (tocopherol), and erythema multiforme–like ACD associated with vitamin K1.

Notably, vitamin B5 has been associated with ACD as an ingredient in hair products, moisturizers, and wound care products, as well as B-complex vitamins and fortified foods, Dr. Ehrlich said.

Herbs and spices can act as allergens as well. Turmeric is a spice that has become a popular supplement ingredient, she said. Turmeric and curcumin (found in turmeric) can be used as a dye for its yellow color as well as a flavoring but has been associated with allergic reactions. Another popular herbal supplement, ginkgo biloba, has been marketed as a product that improves memory and cognition. It is available in pill form and in herbal teas.

“It’s really important to think about what herbal products our patients are taking, and not just in pill form,” Dr. Ehrlich said. “We need to expand our thoughts on what the herbs are in.”
 

Consider food additives as allergens

Food additives, in the form of colorants, preservatives, or flavoring agents, can cause allergic reactions, Dr. Ehrlich noted.

The question of whether food-additive contact sensitivity has a role in the occurrence of atopic dermatitis (AD) in children remains unclear, she said. However, a study published in 2020 found that 62% of children with AD had positive patch test reactions to at least one food-additive allergen, compared with 20% of children without AD. The additives responsible for the most reactions were azorubine (24.4%); formic acid (15.6%); and carmine, cochineal red, and amaranth (13.3% for each).

Common colorant culprits in allergic reactions include carmine, annatto, tartrazine, and spices (such as paprika and saffron), Dr. Ehrlich said. Carmine is used in meat to prevent photo-oxidation and to preserve a red color, and it has other uses as well, she said. Carmine has been associated with ACD, AD flares, and immediate hypersensitivity. Annatto is used in foods, including processed foods, butter, and cheese, to provide a yellow color. It is also found in some lipsticks and has been associated with urticaria and angioedema, she noted.

Food preservatives that have been associated with allergic reactions include butylated hydroxyanisole and sulfites, Dr. Ehrlich said. Sulfites are used to prevent food from turning brown, and it may be present in dried fruit, fruit juice, molasses, pickled foods, vinegar, and wine.

Reports of ACD in response to sodium metabisulfite have been increasing, she noted. Other sulfite reactions may occur with exposure to other products, such as cosmetics, body washes, and swimming pool water, she said.

Awareness of allergens in supplements is important “because the number of our patients taking supplements for different reasons is increasing” and allergens in supplements could account for flares, Dr. Ehrlich said. Clinicians should encourage patients to tell them what supplements they use. Clinicians should review the ingredients in these supplements with their patients to identify potential allergens that may be causing reactions, she advised.

Dr. Ehrlich has disclosed no relevant financial relationships.

Consider popular nutritional supplements as a potential source of allergic reactions if the cause of the reaction is otherwise unknown, Alison Ehrlich, MD, said at the annual meeting of the American Contact Dermatitis Society.

Allergens may be hidden in a range of supplement products, from colorings in vitamin C powders to some vitamins used in hair products and other products.

“In general, our patients do not tell us what supplements they are taking,” said Dr. Ehrlich, a dermatologist who practices in Washington, D.C. Antiaging, sleep, and weight loss/weight control supplements are among the most popular, she said.

Surveys have shown that many patients do not discuss supplement use with their health care providers, in part because they believe their providers would disapprove of supplement use, and patients are not educated about supplements, she said. “This is definitely an area that we should try to learn more about,” she added.

Current regulations regarding dietary supplements stem from the Dietary Supplement Health and Education Act of 1994, which defined dietary supplements as distinct from meals but regulated them as a category of food, not as medications. Dietary supplements can be vitamins, minerals, herbs, and extracts, Dr. Ehrlich said.

“There is not a lot of safety wrapped around how supplements come onto the market,” she explained. “It is not the manufacturer’s responsibility to test these products and make sure they are safe. When they get pulled off the market, it is because safety reports are getting back to the FDA.”

Consequently, a detailed history of supplement use is important, as it may reveal possible allergens as the cause of previously unidentified reactions, she said.

Dr. Ehrlich shared a case involving a patient who claimed to have had a reaction to a “Prevage-like” product that was labeled as a crepe repair cream. Listed among the product’s ingredients was idebenone, a synthetic version of the popular antioxidant known as Coenzyme Q.
 

Be wary of vitamins

Another potential source of allergy is vitamin C supplements, which became especially popular during the pandemic as people sought additional immune system support, Dr. Ehrlich noted. “What kind of vitamin C product our patients are taking is important,” she said. For example, some vitamin C powders contain coloring agents, such as carmine. Some also contain gelatin, which may cause an allergic reaction in individuals with alpha-gal syndrome, she added.

In general, water-soluble vitamins such as vitamins B1 to B9, B12, and C are more likely to cause an immediate reaction, Dr. Ehrlich said. Fat-soluble vitamins, such as vitamins A, D, E, and K, are more likely to cause a delayed reaction of allergic contact dermatitis.

Dr. Ehrlich described some unusual reactions to vitamins that have been reported, including a systemic allergy associated with vitamin B1 (thiamine), burning mouth syndrome associated with vitamin B3 (nicotinate), contact urticaria associated with vitamin B5 (panthenol), systemic allergy and generalized ACD associated with vitamin E (tocopherol), and erythema multiforme–like ACD associated with vitamin K1.

Notably, vitamin B5 has been associated with ACD as an ingredient in hair products, moisturizers, and wound care products, as well as B-complex vitamins and fortified foods, Dr. Ehrlich said.

Herbs and spices can act as allergens as well. Turmeric is a spice that has become a popular supplement ingredient, she said. Turmeric and curcumin (found in turmeric) can be used as a dye for its yellow color as well as a flavoring but has been associated with allergic reactions. Another popular herbal supplement, ginkgo biloba, has been marketed as a product that improves memory and cognition. It is available in pill form and in herbal teas.

“It’s really important to think about what herbal products our patients are taking, and not just in pill form,” Dr. Ehrlich said. “We need to expand our thoughts on what the herbs are in.”
