SEATTLE – Tissue accumulation of advanced glycation end products (AGEs) is associated with the presence of hypercortisolism, suggesting a potential future noninvasive method to assist in the diagnosis of Cushing syndrome, new research suggests.
 

Tissue accumulation of AGEs – harmful compounds formed by glycation of macromolecules – has been implicated in aging, diabetes, and cardiovascular disease. Now, in a new single-center prospective study, a group of 208 patients with endogenous hypercortisolism was found to have significantly higher median tissue AGE levels than 103 reference subjects without hypercortisolism.

The findings were presented at the annual meeting of the American Association of Clinical Endocrinology by Rashi Sandooja, MD, an endocrinology fellow at the Mayo Clinic, Rochester, Minn.

“Diagnosis of endogenous hypercortisolism can be quite challenging. Often patients can have nonspecific symptoms with biochemical testing being equivocal. In these situations, new biomarkers of hypercortisolism such as AGE measurement could potentially be useful,” Dr. Sandooja said in an interview.

“After proper validation, it could help clinicians in cases which may not be straightforward and could serve as an additional” instrument in the toolkit to reach a conclusive diagnosis, she added.

Asked to comment, session moderator Anupam Kotwal, MD, said in an interview: “I think it’s very exciting data. ... I envision its use in mild autonomous cortisol secretion, where there are not a lot of overt Cushing features but they may have a small adrenal mass. ... It might be used to guide care when there’s not a clear-cut answer.”

However, he cautioned that more validation is needed to determine the correlates of AGEs by different etiologies and magnitudes of cortisol excess.

Moreover, “skin can become thin in hypercortisolism, so is [the reader device] just detecting it more with skin testing? I think a blood test for validation would be a very good next step,” added Dr. Kotwal, who is an assistant professor in the division of diabetes, endocrinology and metabolism at the University of Nebraska, Omaha.
 

More work will be needed

Future directions for research should include adding a longitudinal arm and looking at the impact on AGE after patients undergo curative surgery and achieve remission, Dr. Sandooja explained.

“It will be interesting to see if AGE levels continue to be persistently high or decrease after patients achieve sustained remission of hypercortisolism. We are also interested in whether AGE measurement at baseline, prior to surgery may be associated with glucocorticoid withdrawal, myopathy, and metabolic outcomes following the surgery.”

Dr. Kotwal observed: “If the answer is clear for Cushing disease, I don’t know what extra information this would give. Maybe they would monitor people more closely afterward. It would be useful to see, but I think the first low-hanging fruit is use it in a way to guide the care of patients where we’re unclear as to whether initial treatment of this [mild autonomous cortisol secretion] is going to improve their outcomes.”

But, he added, “keeping in mind issues of skin ... we don’t want to distract clinicians and patients from using the tried and tested methods of characterizing Cushing syndrome. I’m always hesitant to bring something into practice before there is a little more information on how it can be used.”

Dr. Sandooja and Dr. Kotwal reported no relevant financial relationships.

SEATTLE – Use of a new kind of assay – sequential beta-hydroxybutyrate testing – with a cut-off for ruling out insulinoma in patients with hypoglycemia may allow for a shortening of the standard 72-hour fasting time, therefore yielding significant hospital cost savings, new data suggest.

Insulinomas are small, rare types of pancreatic tumors that are benign but secrete excess insulin, leading to hypoglycemia. More than 99% of people with insulinomas develop hypoglycemia within 72 hours, hence, the use of a 72-hour fast to detect these tumors.

But most people who are evaluated for hypoglycemia do not have an insulinoma and fasting in hospital for 3 days is burdensome and costly.  

As part of a quality improvement project, Cleveland Clinic endocrinology fellow Michelle D. Lundholm, MD, and colleagues modified their hospital’s protocol to include measurement of beta-hydroxybutyrate (BHB), a marker of insulin suppression, every 12 hours with a cutoff of ≥ 2.7mmol/L for stopping the fast if hypoglycemia (venous glucose ≤ 45mg/dL) hasn’t occurred. This intervention cut in half the number of patients who needed to fast for the full 72 hours, without missing any insulinomas.

“We are excited to share how a relatively simple adjustment to our protocol allowed us to successfully reduce the burden of fasting on patients and more effectively utilize hospital resources. We hope that this encourages other centers to consider doing the same,” Dr. Lundholm said in an interview.

“These data support a 48-hour fast. The literature supports that’s sufficient to detect 95% of insulinomas. ... But, given our small insulinoma cohort, we are looking forward to learning from other studies,” she added.

Dr. Lundholm presented the late-breaking oral abstract at the annual scientific & clinical congress of the American Association of Clinical Endocrinology.

Asked to comment, session moderator Jenna Sarvaideo, MD, said: “We’re often steeped in tradition. That’s why this abstract and this quality improvement project is so exciting to me because it challenges the history. … and I think it’s ultimately helping patients.”

Dr. Sarvaideo, of Clement J. Zablocki VA Medical Center, Milwaukee, noted that, typically, although the fast will be stopped before 72 hours if the patient develops hypoglycemia, “often they don’t, so we keep going on and on. If we just paid more attention to the beta-hydroxybutyrate, I think that would be practice changing.”

She added that more data would be optimal, given that there were under 100 patients in the study, “but I do think that devising protocols is … very much still at the hands of the endocrinologists. I think that this work could make groups reevaluate their protocol and change it, maybe even with a small dataset and then move on from there and see what they see.”

Indeed, Dr. Lundholm pointed out that some institutions, such as the Mayo Clinic, already include 6-hour BHB measurements (along with glucose and insulin) in their protocols.

“For any institution that already draws regular BHB levels like this, it would be very easy to implement a new stopping criterion without adding any additional costs,” she said in an interview.
 

All insulinomas became apparent in less than 48 hours

The first report to look at the value of testing BHB at regular intervals was published by the Mayo Clinic in 2005 after they noticed patients without insulinoma were complaining of ketosis symptoms such as foul breath and digestive problems toward the end of the fast.

However, although BHB testing is used today as part of the evaluation, it’s typically only drawn at the start of the protocol and again at the time of hypoglycemia or at the end of 72 hours because more frequent values hadn’t been thought to be useful for guiding clinical management, Dr. Lundholm explained. 

Between January 2018 and June 2020, Dr. Lundholm and colleagues followed 34 Cleveland Clinic patients who completed the usual 72-hour fast protocol. Overall, 71% were female, and 26% had undergone prior bariatric surgery procedures. Eleven (32%) developed hypoglycemia and stopped fasting. The other 23 (68%) fasted for the full 72 hours.

Dr. Lundholm and colleagues determined that the fast could have ended earlier in 35% of patients based on an elevated BHB without missing any insulinomas.

And so, in June 2020 the group revised their protocol to include the BHB ≥ 2.7mmol/L stopping criterion. Of the 30 patients evaluated from June 2020 to January 2023, 87% were female and 17% had undergone a bariatric procedure.

Here, 15 (50%) reached a BHB ≥ 2.7mmol/L and ended their fast at an average of 43.8 hours. Another seven (23%) ended the fast after developing hypoglycemia. Just eight patients (27%) fasted for the full 72 hours.

Overall, this resulted in approximately 376 fewer cumulative hours of inpatient admission than if patients had fasted for the full time.

Of the 64 patients who have completed the fasting protocol since 2018, seven (11%) who did have an insulinoma developed hypoglycemia within 48 hours and with a BHB < 2.7 mmol/L (median, 0.15).
 

Advantages: cost, adherence

A day in a general medicine bed at Cleveland Clinic was quoted as costing $2,420, based on publicly available information as of Jan. 1, 2023. “If half of patients leave 1 day earlier, this equates to about $1,210 per patient in savings from bed costs alone,” Dr. Lundholm told this news organization.  

The revised protocol required an additional two to four blood draws, depending on the length of the fast. “The cost of these extra blood tests varies by lab and by count, but even at its highest does not exceed the amount of savings from bed costs,” she noted.

Patient adherence is another potential benefit of the revised protocol.

“Any study that requires 72 hours of patient cooperation is a challenge, particularly in an uncomfortable position like fasting. When we looked at these adherence numbers, we found that the percentage of patients who prematurely ended their fast decreased from 35% to 17% with the updated protocol,” Dr. Lundholm continued.

“This translates to fewer inconclusive results and fewer readmissions for repeat 72-hour fasting. While this was not our primary outcome, it was another noted benefit of our change,” she said.

Dr. Lundholm and Dr. Sarvaideo have reported no relevant financial relationships.

SEATTLE – Taking sulfonylureas sold as “street Valium” can lead to severe hypoglycemia that may result in emergency department visits, the latest of a handful of case reports suggest.

“Physicians should be aware of this possibility and consider intentional or unintentional sulfonylurea abuse, with or without other drugs,” Amanda McKenna, MD, a first-year endocrinology fellow at the Mayo Clinic, Jacksonville, Fla., and colleagues say in a poster presented at the annual scientific & clinical congress of the American Association of Clinical Endocrinology.

The new case, seen in Florida, involves a 33-year-old man with a history of narcotic dependence and anxiety but not diabetes. At the time of presentation, the patient was unconscious and diaphoretic. The patient’s blood glucose level was 18 mg/dL. He had purchased two unmarked, light blue pills on the street which he thought were Valiums but turned out to be glyburide.

Sulfonylureas have no potential for abuse, but they physically resemble Valiums and are easier for illicit drug dealers to obtain because they’re not a controlled substance, and they can be sold for considerably more money, Dr. McKenna said in an interview.

“He thought he was getting Valium, but what he really purchased was glyburide. ... When he took it, he developed sweating and weakness. He probably thought he was having a bad trip, but it was really low blood sugar,” she said.
 

Similar cases go back nearly two decades

Similar cases have been reported as far back as 2004 in different parts of the United States. A 2004 article reports five cases in which people in San Francisco were “admitted to the hospital for hypoglycemia as a result of a drug purchased on the streets as a presumed benzodiazepine.”

Two more cases of “glyburide poisoning by ingestion of ‘street Valium,’ ” also from San Francisco, were reported in 2012. And in another case presented at the 2022 Endocrine Society meeting, sulfonylurea had been cut with cocaine, presumably to increase the volume.

The lead author of the 2012 article, Craig Smollin, MD, medical director of the California Poison Control System, San Francisco Division, and professor of emergency medicine at the University of California, San Francisco, told this news organization that his team has seen “a handful of cases over the years” but that “it is hard to say how common it is because hypoglycemia is common in this patient population for a variety of reasons.”
 

Persistent hypoglycemia led to the source

In the current case, paramedics treated the patient with D50W, and his blood glucose level increased from 18 mg/dL to 109 mg/dL. He regained consciousness but then developed recurrent hypoglycemia, and his blood glucose level dropped back to 15 mg/dL in the ED. Urine toxicology results were positive for benzodiazepines, cannabis, and cocaine.

Laboratory results showed elevations in levels of insulin (47.4 mIU/mL), C-peptide (5.4 ng/mL), and glucose (44 mg/dL). He was again treated with D50W, and his blood glucose level returned to normal over 20 hours. Once alert and oriented, he reported no personal or family history of diabetes. A 72-hour fast showed no evidence of insulinoma. A sulfonylurea screen was positive for glyburide. He was discharged home in stable condition. How many more cases have been missed?

Dr. McKenna pointed out that a typical urine toxicology screen for drugs wouldn’t detect a sulfonylurea. “The screen for hypoglycemic agents is a blood test, not a urine screen, so it’s completely different in the workup, and you really have to be thinking about that. It typically takes a while to come back,” she said.

She added that if the hypoglycemia resolves and testing isn’t conducted, the cause of the low blood sugar level might be missed. “If the hypoglycemia doesn’t persist, the [ED] physician wouldn’t consult endocrine. ... Is this happening more than we think?”
 

Ocreotide: A ‘unique antidote’

In their article, Dr. Smollin and colleagues describe the use of ocreotide, a long-acting somatostatin agonist that reverses the insulin-releasing effect of sulfonylureas on pancreatic beta cells, resulting in diminished insulin secretion. Unlike glucose supplementation, ocreotide doesn’t stimulate additional insulin release. It is of longer duration than glucagon, the authors say.

“The management of sulfonylurea overdose includes administration of glucose but also may include the use of octreotide, a unique antidote for sulfonylurea induced hypoglycemia,” Dr. Smollin said.

However, he also cautioned, “there is a broad differential diagnosis for hypoglycemia, and clinicians must consider many alternative diagnoses.”

Dr. McKenna and Dr. Smollin have disclosed no relevant financial relationships.

“Physicians should be aware of this possibility and consider intentional or unintentional sulfonylurea abuse, with or without other drugs,” Amanda McKenna, MD, a first-year endocrinology fellow at the Mayo Clinic, Jacksonville, Fla., and colleagues say in a poster presented at the annual scientific & clinical congress of the American Association of Clinical Endocrinology.

The new case, seen in Florida, involves a 33-year-old man with a history of narcotic dependence and anxiety but not diabetes. At the time of presentation, the patient was unconscious and diaphoretic. The patient’s blood glucose level was 18 mg/dL. He had purchased two unmarked, light blue pills on the street which he thought were Valiums but turned out to be glyburide.

Sulfonylureas have no potential for abuse, but they physically resemble Valiums and are easier for illicit drug dealers to obtain because they’re not a controlled substance, and they can be sold for considerably more money, Dr. McKenna said in an interview.

“He thought he was getting Valium, but what he really purchased was glyburide. ... When he took it, he developed sweating and weakness. He probably thought he was having a bad trip, but it was really low blood sugar,” she said.
 

Similar cases go back nearly two decades

Similar cases have been reported as far back as 2004 in different parts of the United States. A 2004 article reports five cases in which people in San Francisco were “admitted to the hospital for hypoglycemia as a result of a drug purchased on the streets as a presumed benzodiazepine.”

Two more cases of “glyburide poisoning by ingestion of ‘street Valium,’ ” also from San Francisco, were reported in 2012. And in another case presented at the 2022 Endocrine Society meeting, sulfonylurea had been cut with cocaine, presumably to increase the volume.

The lead author of the 2012 article, Craig Smollin, MD, medical director of the California Poison Control System, San Francisco Division, and professor of emergency medicine at the University of California, San Francisco, told this news organization that his team has seen “a handful of cases over the years” but that “it is hard to say how common it is because hypoglycemia is common in this patient population for a variety of reasons.”
 

Persistent hypoglycemia led to the source

In the current case, paramedics treated the patient with D50W, and his blood glucose level increased from 18 mg/dL to 109 mg/dL. He regained consciousness but then developed recurrent hypoglycemia, and his blood glucose level dropped back to 15 mg/dL in the ED. Urine toxicology results were positive for benzodiazepines, cannabis, and cocaine.

Laboratory results showed elevations in levels of insulin (47.4 mIU/mL), C-peptide (5.4 ng/mL), and glucose (44 mg/dL). He was again treated with D50W, and his blood glucose level returned to normal over 20 hours. Once alert and oriented, he reported no personal or family history of diabetes. A 72-hour fast showed no evidence of insulinoma. A sulfonylurea screen was positive for glyburide. He was discharged home in stable condition. How many more cases have been missed?

Dr. McKenna pointed out that a typical urine toxicology screen for drugs wouldn’t detect a sulfonylurea. “The screen for hypoglycemic agents is a blood test, not a urine screen, so it’s completely different in the workup, and you really have to be thinking about that. It typically takes a while to come back,” she said.

She added that if the hypoglycemia resolves and testing isn’t conducted, the cause of the low blood sugar level might be missed. “If the hypoglycemia doesn’t persist, the [ED] physician wouldn’t consult endocrine. ... Is this happening more than we think?”
 

Ocreotide: A ‘unique antidote’

In their article, Dr. Smollin and colleagues describe the use of ocreotide, a long-acting somatostatin agonist that reverses the insulin-releasing effect of sulfonylureas on pancreatic beta cells, resulting in diminished insulin secretion. Unlike glucose supplementation, ocreotide doesn’t stimulate additional insulin release. It is of longer duration than glucagon, the authors say.

“The management of sulfonylurea overdose includes administration of glucose but also may include the use of octreotide, a unique antidote for sulfonylurea induced hypoglycemia,” Dr. Smollin said.

However, he also cautioned, “there is a broad differential diagnosis for hypoglycemia, and clinicians must consider many alternative diagnoses.”

Dr. McKenna and Dr. Smollin have disclosed no relevant financial relationships.

SEATTLE – The latest American Association of Clinical Endocrinology type 2 diabetes management algorithm uses graphics to focus on individualized care while adding newly compiled information about medication access and affordability, vaccinations, and weight loss drugs.

The clinical guidance document was presented at the annual scientific & clinical congress of the American Association of Clinical Endocrinology and simultaneously published in Endocrine Practice.

Using text and colorful graphics, the document summarizes information from last year’s update and other recent AACE documents, including those addressing dyslipidemia and use of diabetes technology.

“The algorithm takes from the larger clinical practice guideline and distills down those management principles in a much more digestible way, and a way that can be used every day in the clinic,” lead author Susan L. Samson, MD, PhD, chair of endocrinology, diabetes & metabolism at the Mayo Clinic Florida, Jacksonville, said in an interview.

Asked to comment, Anne L. Peters, MD, professor of clinical medicine at the University of Southern California, Los Angeles, said: “I like their simple graphics. For the Department of Health Services in Los Angeles County, we have been painstakingly trying to create our own flow diagrams. ... These will help.”
 

Eleven separate algorithms with text and graphics

Included are 11 visual management algorithms, with accompanying text for each one. The first lists 10 overall management principles, including “lifestyle modification underlies all therapy,” “maintain or achieve optimal weight,” “choice of therapy includes ease of use and access,” “individualize all glucose targets,” “avoid hypoglycemia,” and “comorbidities must be managed for comprehensive care.”

Three more algorithms cover the diabetes-adjacent topics of adiposity-based chronic disease, prediabetes, dyslipidemia, and hypertension.

Four separate graphics address glucose-lowering. Two are “complications-centric” and “glucose-centric” algorithms, another covers insulin initiation and titration, and a table summarizes the benefits and risks of currently available glucose-lowering medications, as well as cost.

Splitting the glucose-lowering algorithms into “complications-centric” and “glucose-centric” graphics is new, Dr. Samson said. “The complications one comes first, deliberately. You need to think about: Does my patient have a history of or high risk for cardiovascular disease, heart failure, stroke, or diabetic kidney disease? And, you want to prioritize those medications that have evidence to improve outcomes with those different diabetes complications versus a one-size-fits-all approach.”

And for patients without those complications, the glucose-centric algorithm considers obesity, hypoglycemia risk, and access/cost issues. “So, overall the diabetes medication algorithm has been split in order to emphasize that personalized approach to decision-making,” Dr. Samson explained.

Also new is a table listing the benefits and risks of weight-loss medications, and another covering immunization guidance for people with diabetes based on recommendations from the U.S. Centers for Disease Control and Prevention. “Coming out of the pandemic, we’re thinking about how can we protect our patients from infectious disease and all the comorbidities. In some cases, people with diabetes can have a much higher risk for adverse events,” Dr. Samson noted.

Regarding the weight-loss medications table, she pointed out that the task force couldn’t include the blockbuster twincretin tirzepatide because it’s not yet approved for weight loss by the U.S. Food and Drug Administration. However, it is included in the glucose-lowering drug table with weight loss listed among its benefits.

“We want this to be a living document that should be updated in a timely fashion, and so, as these new indications are approved and we see more evidence supporting their different uses, this should be updated in a really timely fashion to reflect that,” Dr. Samson said.

The end of the document includes a full page of each graphic, meant for wall posting.

Dr. Peters noted that for the most part, the AACE guidelines and algorithm align with joint guidance by the American Diabetes Association and European Association for the Study of Diabetes.

“For many years there seemed to be big differences between the AACE and ADA guidelines for the management of type 2 diabetes. Although small differences still exist ... the ADA and AACE guidelines have become quite similar,” she said.

Dr. Peters also praised the AACE algorithm for providing “a pathway for people who have issues with access and cost.”

“I am incredibly proud that in the County of Los Angeles you can get a [glucagon-like peptide-1 receptor agonist] and/or a [sodium-glucose cotransporter-2 inhibitor] even with the most restricted MediCal insurance if indications are met. But there remain many people in many places where access and cost limit options, and I am grateful that AACE includes this in their algorithms,” she said.

Dr. Samson has reported receiving research support to the Mayo Clinic from Corcept, serving on a steering committee and being a national or overall principal investigator for Chiasma and Novartis, and being a committee chair for the American Board of Internal Medicine. Dr. Peters has reported relationships with Blue Circle Health, Vertex, and Abbott Diabetes Care, receiving research grants from Abbott Diabetes Care and Insulet, and holding stock options in Teladoc and Omada Health.

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.

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.

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.”

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.

An investigational outpatient endoscopic procedure may help eliminate the need for insulin in people with type 2 diabetes, early research suggests.

Called recellularization via electroporation therapy (ReCET), the technology, manufactured by Endogenex, uses a specialized catheter to deliver alternating electric pulses to the duodenum to induce cellular regeneration. This process is thought to improve insulin sensitivity, in part, by altering gut hormones and nutritional sensing, principal investigator Jacques Bergman, MD, PhD, said in a press briefing held in conjunction with the annual Digestive Disease Week® (DDW), where he will present the data on May 9.

In the first-in-human study of ReCET, 12 of 14 patients were able to come off insulin for up to a year following the procedure when combined with the use of the glucagonlike peptide–1 agonist semaglutide.

“This might be a game changer in the management of type 2 diabetes because a single outpatient endoscopic intervention was suggested to have a pretty long therapeutic effect, which is compliance-free, as opposed to drug therapy that relies on patients taking the drugs on a daily basis,” said Dr. Bergman, professor of gastrointestinal endoscopy at Amsterdam University Medical Center.

Moreover, he added, “this technique is disease-modifying, so it goes to the root cause of type 2 diabetes and tackles the insulin resistance, as opposed to drug therapy, which at best, is disease-controlling, and the effect is immediately gone if you stop the medication.”

ReCET is similar to another product, Fractyl’s Revita DMR, for which Dr. Bergman was involved in a randomized clinical trial. He said in an interview that the two technologies differ in that the Revita uses heat with submucosal lifting to avoid deeper heat penetration, whereas ReCET is nonthermal. He is also involved in a second randomized trial of the Revita.
 

Is semaglutide muddying the findings?

Asked to comment about the current study with ReCET, Ali Aminian, MD, professor of surgery and director of the Bariatric and Metabolic Institute at the Cleveland Clinic, said that the treatment effect is certainly plausible.

“The observation that hyperglycemia rapidly and substantially improves after bariatric surgery has prompted innovators to search for novel endoscopic procedures targeting the GI tract to improve diabetes and metabolic disease. Over the years, we learned that in addition to its role in digestion and absorption, the GI tract is actually a large endocrine organ which contributes to development of diabetes and metabolic disease.”

However, Dr. Aminian said that, “while these preliminary findings on a very small number of patients with a very short follow-up time are interesting,” he faulted the study design for including semaglutide. “When patients are treated with a combination of therapies, it will be hard to understand the true effect of each therapy,” and particularly, “when we add a strong diabetes medication like semaglutide.”

Dr. Bergman said semaglutide was used to “boost the insulin-resistant effect of the endoscopic treatment,” and that a planned double-blind, randomized trial will “show how much semaglutide actually contributed to the effect.” The ultimate goal, he noted, is to eliminate the need for all medications.

Moreover, when people with type 2 diabetes add semaglutide to insulin treatment, only about 20% typically are able to quit taking the insulin, in contrast to the 86% seen in this study, lead author Celine Busch, MBBS, a PhD candidate in gastroenterology at Amsterdam University, said in a DDW statement.

Dr. Aminian said, “I’m looking forward to better quality data ... from studies with a stronger design to prove safety, efficacy, and durability of this endoscopic intervention in patients with diabetes.”

But, he also cautioned, “in the past few years, other endoscopic procedures targeting the duodenum were introduced with exciting initial findings based on a small series [with a] short-term follow-up time. However, their safety, efficacy, and durability were not proven in subsequent studies.”
 

All patients stopped insulin, most for a year

The single-arm, single-center study involved 14 patients with type 2 diabetes taking basal but not premeal insulin. All underwent the 1-hour outpatient ReCET procedure, which involved placing a catheter into the first part of the small bowel and delivering electrical pulses to the duodenum.

Patients adhered to a calorie-controlled liquid diet for 2 weeks, after which they were initiated on semaglutide. All 14 patients were able to come off insulin for 3 months while maintaining glycemic control, and 12 were able to come off insulin for 12 months. They also experienced a 50% reduction in liver fat.

Dr. Bergman said a randomized, double-blind study using a sham procedure for controls is expected to start in about 2 months. “But for now, we are very encouraged by the potential for controlling type 2 diabetes with a single endoscopic treatment.”

Dr. Bergman has reported serving on the advisory board for Endogenex. Dr. Aminian has reported receiving research support and honorarium from Medtronic and Ethicon.

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

“This might be a game changer in the management of type 2 diabetes because a single outpatient endoscopic intervention was suggested to have a pretty long therapeutic effect, which is compliance-free, as opposed to drug therapy that relies on patients taking the drugs on a daily basis,” said Dr. Bergman, professor of gastrointestinal endoscopy at Amsterdam University Medical Center.

Moreover, he added, “this technique is disease-modifying, so it goes to the root cause of type 2 diabetes and tackles the insulin resistance, as opposed to drug therapy, which at best, is disease-controlling, and the effect is immediately gone if you stop the medication.”

ReCET is similar to another product, Fractyl’s Revita DMR, for which Dr. Bergman was involved in a randomized clinical trial. He said in an interview that the two technologies differ in that the Revita uses heat with submucosal lifting to avoid deeper heat penetration, whereas ReCET is nonthermal. He is also involved in a second randomized trial of the Revita.
 

Is semaglutide muddying the findings?

Asked to comment about the current study with ReCET, Ali Aminian, MD, professor of surgery and director of the Bariatric and Metabolic Institute at the Cleveland Clinic, said that the treatment effect is certainly plausible.

“The observation that hyperglycemia rapidly and substantially improves after bariatric surgery has prompted innovators to search for novel endoscopic procedures targeting the GI tract to improve diabetes and metabolic disease. Over the years, we learned that in addition to its role in digestion and absorption, the GI tract is actually a large endocrine organ which contributes to development of diabetes and metabolic disease.”

However, Dr. Aminian said that, “while these preliminary findings on a very small number of patients with a very short follow-up time are interesting,” he faulted the study design for including semaglutide. “When patients are treated with a combination of therapies, it will be hard to understand the true effect of each therapy,” and particularly, “when we add a strong diabetes medication like semaglutide.”

Dr. Bergman said semaglutide was used to “boost the insulin-resistant effect of the endoscopic treatment,” and that a planned double-blind, randomized trial will “show how much semaglutide actually contributed to the effect.” The ultimate goal, he noted, is to eliminate the need for all medications.

Moreover, when people with type 2 diabetes add semaglutide to insulin treatment, only about 20% typically are able to quit taking the insulin, in contrast to the 86% seen in this study, lead author Celine Busch, MBBS, a PhD candidate in gastroenterology at Amsterdam University, said in a DDW statement.

Dr. Aminian said, “I’m looking forward to better quality data ... from studies with a stronger design to prove safety, efficacy, and durability of this endoscopic intervention in patients with diabetes.”

But, he also cautioned, “in the past few years, other endoscopic procedures targeting the duodenum were introduced with exciting initial findings based on a small series [with a] short-term follow-up time. However, their safety, efficacy, and durability were not proven in subsequent studies.”
 

All patients stopped insulin, most for a year

The single-arm, single-center study involved 14 patients with type 2 diabetes taking basal but not premeal insulin. All underwent the 1-hour outpatient ReCET procedure, which involved placing a catheter into the first part of the small bowel and delivering electrical pulses to the duodenum.

Patients adhered to a calorie-controlled liquid diet for 2 weeks, after which they were initiated on semaglutide. All 14 patients were able to come off insulin for 3 months while maintaining glycemic control, and 12 were able to come off insulin for 12 months. They also experienced a 50% reduction in liver fat.

Dr. Bergman said a randomized, double-blind study using a sham procedure for controls is expected to start in about 2 months. “But for now, we are very encouraged by the potential for controlling type 2 diabetes with a single endoscopic treatment.”

Dr. Bergman has reported serving on the advisory board for Endogenex. Dr. Aminian has reported receiving research support and honorarium from Medtronic and Ethicon.

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

Seasonal variation in one of the hormones used to monitor thyroid function could in turn lead to false diagnoses of subclinical hypothyroidism and unnecessary prescriptions of levothyroxine, according to Yale clinical chemist Joe M. El-Khoury, PhD.

A Japanese study of more than 7,000 healthy individuals showed that thyrotropin-stimulating hormone (TSH) varies widely throughout the seasons, he said, peaking in the northern hemisphere’s winter months (January to February) with its low in the summer months (June to August). That paper was published last year in the Journal of the Endocrine Society.

But free thyroxine (FT4) levels in the Japanese population remained relatively stable, he wrote in a letter recently published in Clinical Chemistry.

“If you end up with a mildly elevated TSH result and a normal FT4, try getting retested 2-3 months later to make sure this is not a seasonal artifact or transient increase before prescribing/taking levothyroxine unnecessarily,” advised Dr. El-Khoury, director of Yale University’s Clinical Chemistry Laboratory, New Haven, Conn.

“Because the [population-based, laboratory] reference ranges don’t account for seasonal variation, we’re flagging a significant number of people as high TSH when they’re normal, and physicians are prescribing levothyroxine inappropriately to healthy people who don’t need it,” he told this news organization, adding that overtreatment can be harmful, particularly for elderly people.

This seasonal variation in TSH could account for between a third to a half of the 90% of all levothyroxine prescriptions that were found to be unnecessary, according to a U.S. study in 2021, Dr. El-Khoury added.

In a comment, Trisha Cubb, MD, said that Dr. El-Khoury’s letter “raises a good point, that we really need to look at our reference ranges, especially when more and more studies are showing that so many thyroid hormone prescriptions may not be necessary.”

Dr. Cubb, thyroid section director and assistant professor of clinical medicine at Weill Cornell Medical College/Houston Methodist Academic Institute, Texas, also agrees with Dr. El-Khoury’s suggestion to repeat lab results in some instances.

“I think repeating results, especially in our patients with subclinical disease, is important,” she noted.

And she pointed out that seasonal variation isn’t the only relevant variable. “We also know that multiple clinical factors like pregnancy status, coexisting comorbidities, or age can all influence what we as clinicians consider an acceptable TSH range in an individual patient.” And other medications, such as steroids, or supplements like biotin, “can all affect thyroid lab values,” she noted.

“Ensuring that minor abnormalities aren’t transient is important prior to initiating medical therapy. With any medical therapy there are possible side effects, along with time, cost, [and] monitoring, all of which can be associated with thyroid hormone replacement.”
 

TSH reference ranges should be adapted for subpopulations

Dr. El-Khoury explained that to get an idea of how big the seasonal differences in TSH observed in the Japanese study were, “the upper end of the population they tracked goes from 5.2 [mIU/L] in January to 3.4 [mIU/L] in August. So you have almost a 2-unit change in concentration that can happen in the reference population. But laboratory reference ranges, or ‘normal ranges,’ are usually fixed and don’t change by season.”

The higher the TSH, the more likely a person is to have hypothyroidism. Major recent studies have found no benefit of levothyroxine treatment with TSH levels below 7.0-10.0 mIU/L, he said.

“So, I suggest that the limit should be 7.0 [mIU/L] to be safe, but it could be as high as 10 [mIU/L]. In any case, let’s shift the mindset to clinical outcome–based treatment cutoffs,” he said, noting that this approach is currently used for decisions on cholesterol-lowering therapy or vitamin D supplementation, for example.

Regarding this suggestion of using a TSH cutoff of 7 mIU/L to diagnose subclinical hypothyroidism, Dr. Cubb said: “It really depends on the specific population. In an elderly patient, a higher TSH may be of less clinical concern when compared to a female who is actively trying to get pregnant.

“Overall, I think we do need to better understand what appropriate TSH ranges are in specific subpopulations, and then with time, make this more understandable and available for general medicine as well as subspecialty providers to be able to utilize,” she noted.

Regarding the particular Japanese findings cited by Dr. El-Khoury, Dr. Cubb observed that this was a very specific study population, “so we would need more data showing that this is more generalizable.”

And she noted that there’s also diurnal variation in TSH. “In the [Japanese] paper, patients had their thyroid labs drawn between 8:00 a.m. and 9:00 a.m. in a fasting state. Oftentimes in the U.S., thyroid labs are not drawn at specific times or [during] fasting. I think this is one of many factors that should be considered.”
 

Acknowledging seasonal variation would be a start

But overall, Dr. Cubb said that both the Japanese study and Dr. El-Khoury’s letter highlight “how season, in and of itself, which is not something we usually think about, can affect thyroid lab results. I believe as more data come out, more generalizable data, that’s how evidence-based guidelines are generated over time.”

According to Dr. El-Khoury, fixing the laboratory reference range issues would likely require a joint effort of professional medical societies, reference laboratories, and assay manufacturers. But with seasonal variation, that might be a difficult task.

“The problem is, in laboratory medicine, we don’t have rules for an analyte that changes by season to do anything different. My goal is to get people to at least acknowledge this is a problem and do something,” he concluded.

Dr. El-Khoury and Dr. Cubb have reported no relevant financial relationships.

The Food and Drug Administration has approved Medtronic Minimed’s 780G automated insulin delivery system with the Guardian 4 sensor.

The latest so-called artificial pancreas system is approved for people aged 7 years and older who have type 1 diabetes. Medtronic will begin taking preorders for the 780G on May 15, 2023. Users of the current MiniMed 770G will be eligible for no-cost remote software upgrades.

The 780G is currently available in 105 countries. It has been available in Europe since 2020 and in the United Kingdom since 2021. It is the first automated insulin delivery system to automatically administer bolus correction insulin doses every 5 minutes to correct meal-related hyperglycemia.

This so-called meal detection technology doesn’t replace manual premeal boluses but does provide extra insulin if the premeal bolus is skipped or is insufficient.

As with other automated systems, the 780G automatically adjusts basal insulin doses up or down based on glucose levels and trends and shuts off insulin delivery to prevent hypoglycemia. The insulin pump’s infusion set can be worn for 7 days, rather than 3 days as with the older system, and the glucose target level can be set as low as 100 mg/dL.

And in contrast to the older MiniMed 670G system, which tended to frequently boot users out of automated mode, with the 780G, users spent an average of 95% of the time in the automated “SmartGuard” mode.

In the pivotal U.S. trial, overall, patients who used the 780G spent 75% of the time in ideal glucose range (70-180 mg/dL) and 1.8% of the time below that range. Overnight, the figures were 82% and 1.5%, respectively. With the glucose target set at 100 mg/dL and active insulin time set to 2 hours, patients spent 78.8% of time in range without increased hyperglycemia.

In the ADAPT study, with the 780G, there was a 26% increase in time in ideal glucose range and a 1.4% reduction in A1c compared with results for patients who received multiple daily insulin injections with intermittently scanned continuous glucose monitoring, without an increase in hypoglycemia. Overnight, time in range increased 30.2%. The results were sustained at 1 year.

Medicare is now covering continuous glucose monitoring (CGM) for all beneficiaries with diabetes who use insulin, as well as those with a “history of problematic hypoglycemia.”

The new policy decision, announced earlier this year by the Centers for Medicare and Medicaid Services, means that coverage is expanded to those who take even just a single dose of basal insulin daily or who don’t take insulin but who for other reasons experience “problematic” hypoglycemia, defined as a history of more than one level 2 event (glucose < 54 mg/dL) or at least one level 3 event (< 54 mg/dL requiring assistance).

Previously, coverage was limited to those taking frequent daily insulin doses.  

The additional number of people covered, most with type 2 diabetes, is estimated to be at least 1.5 million. That number could more than double if private insurers follow suit, reported an industry analyst.

Chuck Henderson, chief executive officer of the American Diabetes Association, said in a statement: “We applaud CMS’ decision allowing for all insulin-dependent people as well as others who have a history of problematic hypoglycemia to have access to a continuous glucose monitor, a potentially life-saving tool for diabetes management.”

According to Dexcom, which manufacturers the G6 and the recently approved G7 CGMs, the decision was based in part on their MOBILE study. The trial demonstrated the benefit of CGM in people with type 2 diabetes who use only basal insulin or have a history of problematic hypoglycemic events.

On April 14, Abbott, which manufactures the Freestyle Libre 2 and the recently approved Libre 3, received clearance from the U.S. Food and Drug Administration for the Libre 3’s stand-alone reader device. Previously, the Libre 3 had been approved for use only with a smartphone app. The small handheld reader is considered durable medical equipment, making it eligible for Medicare coverage. Abbott is “working on having the FreeStyle Libre 3 system available to Medicare beneficiaries,” the company said in a statement.

The additional number of people covered, most with type 2 diabetes, is estimated to be at least 1.5 million. That number could more than double if private insurers follow suit, reported an industry analyst.

Chuck Henderson, chief executive officer of the American Diabetes Association, said in a statement: “We applaud CMS’ decision allowing for all insulin-dependent people as well as others who have a history of problematic hypoglycemia to have access to a continuous glucose monitor, a potentially life-saving tool for diabetes management.”

According to Dexcom, which manufacturers the G6 and the recently approved G7 CGMs, the decision was based in part on their MOBILE study. The trial demonstrated the benefit of CGM in people with type 2 diabetes who use only basal insulin or have a history of problematic hypoglycemic events.

On April 14, Abbott, which manufactures the Freestyle Libre 2 and the recently approved Libre 3, received clearance from the U.S. Food and Drug Administration for the Libre 3’s stand-alone reader device. Previously, the Libre 3 had been approved for use only with a smartphone app. The small handheld reader is considered durable medical equipment, making it eligible for Medicare coverage. Abbott is “working on having the FreeStyle Libre 3 system available to Medicare beneficiaries,” the company said in a statement.
