MADRID – A late diagnosis of chronic kidney disease is cause for concern. Scientific societies are therefore advocating for screening at younger ages to reverse this trend and slow the progression of the disease. Nearly all patients seen in primary care are candidates for screening because of their risk factors for kidney disease.

During the 29th National Conference of General and Family Medicine of the Spanish Society for General and Family Physicians, Teresa Benedito, MD, family doctor and member of the society’s cardiovascular group, and Roberto Alcázar, MD, nephrologist at the Infanta Leonor University Hospital, Madrid, presented a clinical case encountered in primary care. They used this case to frame a strong argument for the importance of early screening for chronic kidney disease, and they discussed how to properly manage such screening.

The presentation followed the guidelines in the SEMG publication regarding the management and referral of patients with type 2 diabetes. Dr. Benedito explained that the first thing to ask oneself during a patient visit is “whether they present risk factors for kidney disease. If so, we can’t let them leave before we do a kidney screening.” She then listed the factors in question: age older than 60 years, African heritage, family history of chronic kidney disease, decreased kidney mass, weight loss at birth, hypertension, diabetes, smoking, obesity, and low socioeconomic status.

For his part, Dr. Alcázar mentioned how these factors are similar to cardiovascular risk factors, because “the kidneys are a ball of vessels with double capillarization for purifying blood. They’re the organs with the most arteries per unit of weight, so anything that can damage the arteries can damage the kidneys.”
 

Candidates for screening

“Chronic kidney disease develops in 15% of the adult population in Spain. So, it’s worth asking how many patients have been diagnosed and who should we should be screening.” To the factors listed above, Dr. Alcázar added treatment with nephrotoxic drugs (including nonsteroidal anti-inflammatory drugs) for patients with obstructive urinary tract disease, and a history of acute kidney injury for patients with chronic autoimmune disease or neoplasms. “Thus, nearly all patients seen in primary care would need to be screened.”

Another fundamental question raised was whether patients should be screened before age 60 years. “As a nephrologist, I feel that we have been diagnosing chronic kidney disease late, even though we’ve been doing everything by the book,” said Dr. Alcázar. In his opinion, “the answer to whether we should be screening earlier ... is yes, for two reasons: first, because it’s cost-effective, and second, because it’s very inexpensive.”

Dr. Benedito explained in detail the process for diagnosing this disease. She began by defining the disease as changes in kidney structure and function that last longer than 3 months. These changes are identified by use of two criteria: glomerular filtration rate less than 60 mL/min and kidney injury or lesions with or without reduced filtration rate (renal biopsy, albumin/creatinine ratio greater than 30 mg/g, proteinuria, alterations in urinary sediment or in imaging tests). Thus, “if one of these two criteria persists for more than 3 months, the diagnosis is chronic kidney disease. Also, high creatinine levels are not diagnostic for the disease,” she emphasized.
 

Two related parameters

Glomerular filtration and albuminuria “are highly relevant, because screening for chronic kidney disease is based on these two parameters,” said Dr. Benedito. Glomerular filtration rate varies with age, sex, ethnicity, and body mass. It is useful for identifying the stage of the disease and for monitoring disease progression. Albuminuria, on the other hand, is an indication of the severity of the disease. It’s an early marker for kidney injury and systemic disease and is more sensitive than proteinuria. Therefore, “this factor, together with glomerular filtration rate, allows us to detect, classify, and monitor the progression of chronic kidney disease.”

On this point, Dr. Alcázar emphasized the importance of trends, since variation in glomerular filtration depends on serum creatinine, which can vary by nearly 9%. He explained that glomerular filtration rate is related to the number of nephrons remaining. A glomerular filtration rate of less than 60 mL/min implies that more than half of the nephrons in each kidney have been lost. Albuminuria informs about structural damage (that is, the condition of the remaining nephrons). It’s therefore essential to test for both parameters. “We need to be actively monitoring and then making our decisions based on trends and not on isolated results. We need to be aware of albuminuria when we make our decisions,” said Dr. Alcázar. Some studies have shown the importance of testing for albuminuria whenever creatinine level is assessed. “We need to buy into this. If we don’t do this, we’ll only ever have half the information we need.”
 

Reducing late diagnosis

According to the IBERICAN study, 14% of patients seen in primary care in Spain have chronic kidney disease. “This statistic should make us stop and think, own our responsibility, and ask ourselves why this screening isn’t taking place [earlier],” said Dr. Benedito. She added, “We need to head off this trend toward late diagnosis. As the disease progresses, it significantly increases cardiovascular risk and leads to higher mortality, going on dialysis, transplants, et cetera.”

Dr. Alcázar noted that 80% of nephrology cases that are referred to him come from primary care. He explained the need to understand that “these patients have a sevenfold greater risk of suffering a serious cardiovascular event within the next year than people without kidney problems.” Most of these patients will experience an event, even if they don’t undergo dialysis (stage 3 and those near stage 4).
 

Correct staging

Also fundamental is having a detailed understanding of how staging is performed. Dr. Benedito explained that a chart that pairs glomerular filtration rate (six categories) with the level of albuminuria (three categories) should be used during the visit. For example, a case might be classified as G3a-A2. However, the simplified form of the chart may prove more practical. It classifies chronic kidney disease as being associated with mild, moderate, and severe risk, using different colors to aid comprehension.

Dr. Alcázar noted that the latest guidelines from the European Society of Hypertension for 2023 include albuminuria as an important parameter. The guidelines indicate that for a patient with moderate or severe risk, it is not necessary to calculate their score. “It’s considered high cardiovascular risk, and steps would need to be taken for intervention.”

He then listed the tools available for reversing albuminuria. The process begins by reducing salt consumption and involves the use of medications (angiotensin-converting enzyme inhibitors/angiotensin II receptor antagonists, aldosterone receptor antagonists, glucagon-like peptide-1 analogues, and sodium-glucose cotransporter-2 inhibitors, which slow kidney damage regardless of other measures) and strict management of cardiovascular risk factors (smoking, weight management, blood glucose, hypertension, and moderate physical activity).
 

Reducing cardiovascular risk

Dr. Alcázar highlighted important factors to keep in mind when managing each of the cardiovascular risk factors. For hypertension, the aim is to achieve levels less than 130/80 mm Hg, although recommendations vary, depending on the guidelines consulted. “KDIGO (Kidney Disease: Improving Global Outcomes) 2021 states that there is no evidence for monitoring diastolic blood pressure, only systolic blood pressure. If we measure it according to the standardized form, SBP should be less than 120 mm Hg, and if not, we would fall back on readings of 130/80 mm Hg.”

For lipid control (specifically, low-density lipoprotein cholesterol), the staging chart indicates that for patients at mild risk, levels should be less than 100 mg/dL; for those at moderate risk, less than 70 mg/dL; and for those at severe risk, less than 55 mg/dL. Hypertriglyceridemia “should only be treated with fibrates if it comes in over 1,000 mg/dL. Also, care must be taken, because these drugs interfere with creatinine excretion, increasing it,” said Dr. Alcázar.

Guidelines from the KDIGO and the American Diabetes Association state that anyone with diabetes and chronic kidney disease should receive a sodium-glucose cotransporter-2 inhibitor if their glomerular filtration rate exceeds 20 mL/min, “which may contradict slightly what it says on the label. Also, if they have hypertension, they should take an angiotensin-converting enzyme inhibitor,” said Dr. Alcázar. He added that “oral antidiabetics, including metformin, must be adjusted based on renal function if glomerular filtration rate is under 30 mL/min.”
 

Act immediately

When asked whether the course of chronic kidney disease can be changed, Dr. Alcázar responded with an emphatic yes and added that cardiovascular risk can also be substantially reduced. “As nephrologists, we don’t have access to patients in early stages. But family doctors do. Hence the importance of early screening, because going on dialysis at age 60 isn’t the same as at 80.” Currently, “scientific societies are encouraging authorities to screen for chronic kidney disease at earlier ages.”

Regarding drug-based therapy, Dr. Alcázar said that “empagliflozin is not currently indicated for chronic kidney disease in adults.” This sodium-glucose cotransporter-2 inhibitor delays kidney disease and reduces morbidity. Both benefits were highlighted in two recent studies (DAPA-CKD and CREDENCE). Published in January, EMPA-KIDNEY presents a new twist on nephroprotection for patients with chronic kidney disease (diabetic or not) whose glomerular filtration rates are between 20 and 40 mL/min without albuminuria or whose glomerular filtration rates are between 45 and 90 mL/min with albuminuria. For more than 6,000 patients, empagliflozin was observed “to clearly reduce kidney disease progression, cardiovascular mortality and all-cause mortality, and the need to go on dialysis,” stated Dr. Alcázar.
 

What professionals expect

Dr. Benedito also explained the criteria for referral to a specialist: glomerular filtration rate less than 30 mL/min (unless the patient is older than 80 years and does not have progressively worsening renal function), albumin/creatinine ratio greater than 300 mg/g, acute worsening of renal function, progressive worsening of renal function of greater than 5 mL/min/yr, chronic kidney disease, hypertension treated with triple therapy (including a diuretic) at maximum doses, anemia of less than 10 g/dL, and nonurologic hematuria, especially in combination with albuminuria.

Dr. Benedito explained what nephrologists expect from family doctors in the management of chronic kidney disease: “screening for early detection, identifying and treating risk factors for chronic kidney disease, detecting progression and complications, adjusting drugs based on glomerular filtration rate, and ensuring that our patients are benefiting from sodium-glucose cotransporter-2 inhibitors. These are among the most important steps to be taken.”

Dr. Alcázar mentioned what family doctors expect from nephrologists: “two-way communication, accessibility, coordination of actions to be taken, and using shared and mutually agreed-upon protocols.”

The incidence of type 1 diabetes has risen during the COVID-19 pandemic, according to a recent meta-analysis.

The review compared 2 years of data from during the pandemic to data from a prepandemic period, and showed a higher incidence of type 1 diabetes in the first year (incidence rate ratio, 1.14) and second year (IRR, 1.27) of the pandemic. The investigators also found an increase in the incidence of diabetic ketoacidosis (DKA) (IRR, 1.26).

The meta-analysis included 17 studies of 38,149 children and adolescents with newly diagnosed type 1 diabetes. “Putting them all together really gave us more confidence to say this is something that we think is real,” study author Rayzel Shulman, MD, PhD, an endocrinologist at The Hospital for Sick Children in Toronto and associate professor of pediatrics at the University of Toronto, said in an interview.

The study was published in JAMA Network Open.
 

Increased incidence

The investigators reviewed 42 studies, including 17 that examined rates of type 1 diabetes incidence, 10 on type 2 diabetes, and 15 on DKA. The included studies all had a minimum observation period of 12 months during the pandemic and at least 12 months before it. Relative to the prepandemic period, the meta-analysis found higher rates of type 1 diabetes and DKA during the pandemic.

The review was conducted in response to questions about the methodology of study results suggesting an association between the COVID-19 pandemic and the incidence of diabetes, according to Dr. Shulman.

Although this is not the first review of studies on the connection between diabetes and COVID-19, it adds to the literature by extending the study period to 2 years of the pandemic. The longer time frame helps address potential seasonal differences in incidence and increases confidence in the results.

The investigators also sought to look at the incidence of type 2 diabetes in children but found few studies that met the study criteria. Although some studies reported rates of type 2 diabetes, most lacked information about the population, specifically, the “denominator” needed for findings regarding any association with the COVID-19 pandemic.

With greater confidence in the increased incidence of type 1 diabetes, Dr. Shulman emphasized a need to ensure sufficient resources to care for newly diagnosed patients, including education and support for families.

The study’s secondary outcome was the change in incidence rate of DKA among children with newly diagnosed diabetes. Data reported in 15 studies showed a 26% increase in DKA incidence during the first year of the pandemic.

“DKA is a serious and life-threatening condition that is preventable,” said Dr. Shulman. Symptoms of type 1 diabetes include increased thirst and urination, weight loss, and fatigue. If parents or caregivers notice these signs, Dr. Shulman advises them to seek care immediately to reduce the risk of DKA.
 

Possible mechanisms

In a comment, Elizabeth Sellers, MD, an endocrinologist at the Children’s Hospital Research Institute of Manitoba and associate professor of pediatrics at the University of Manitoba, both in Winnipeg, said the study’s findings on DKA are an important reminder to be attentive to symptoms of diabetes. Dr. Sellers did not participate in the meta-analysis.

One possible explanation for the increase is a hesitancy to seek care among parents and caregivers during the pandemic. “I think we use that information and turn it into a positive,” said Dr. Sellers, by increasing recognition of the symptoms. Dr. Sellers, whose research is included in the review, is part of an initiative by the Canadian Pediatric Endocrine Group to increase diabetes awareness.

The study provides important findings, particularly the second-year results, but is not designed to answer why there has been an increase in diabetes incidence, said Dr. Sellers. “You have to identify the problem first and then you can go back and look at mechanisms.”

The meta-analysis did not seek to draw conclusions about the underlying mechanisms that would explain changes in diabetes incidence but rather indicates a need for further studies to seek a better understanding of the connection. Several theories may be considered, wrote Clemens Kamrath, MD, of the Centre of Child and Adolescent Medicine at Justus Liebig University in Giessen, Germany, and colleagues in an accompanying editorial.

Studies have suggested a direct effect of infections such as COVID-19, whereby the virus damages insulin-producing beta cells. However, the commentary notes these studies do not account for asymptomatic infections among children.

Dr. Kamrath and colleagues also considered the indirect effects of the COVID-19 pandemic, which they indicate may be more likely than direct effects. These indirect effects include autoimmunity and environmental changes that occurred during the pandemic.

Researchers will need to continue monitoring the data to see if the trend persists and continue working to determine the mechanisms, said Dr. Schulman. “I don’t think this is the end of the story.”

The study was supported in part by grant funding from the department of pediatrics at The Hospital for Sick Children. Dr. Shulman, Dr. Sellers, and Dr. Kamrath reported no relevant financial relationships.

The incidence of type 1 diabetes has risen during the COVID-19 pandemic, according to a recent meta-analysis.

The review compared 2 years of data from during the pandemic to data from a prepandemic period, and showed a higher incidence of type 1 diabetes in the first year (incidence rate ratio, 1.14) and second year (IRR, 1.27) of the pandemic. The investigators also found an increase in the incidence of diabetic ketoacidosis (DKA) (IRR, 1.26).

The meta-analysis included 17 studies of 38,149 children and adolescents with newly diagnosed type 1 diabetes. “Putting them all together really gave us more confidence to say this is something that we think is real,” study author Rayzel Shulman, MD, PhD, an endocrinologist at The Hospital for Sick Children in Toronto and associate professor of pediatrics at the University of Toronto, said in an interview.

The study was published in JAMA Network Open.
 

Increased incidence

The investigators reviewed 42 studies, including 17 that examined rates of type 1 diabetes incidence, 10 on type 2 diabetes, and 15 on DKA. The included studies all had a minimum observation period of 12 months during the pandemic and at least 12 months before it. Relative to the prepandemic period, the meta-analysis found higher rates of type 1 diabetes and DKA during the pandemic.

The review was conducted in response to questions about the methodology of study results suggesting an association between the COVID-19 pandemic and the incidence of diabetes, according to Dr. Shulman.

Although this is not the first review of studies on the connection between diabetes and COVID-19, it adds to the literature by extending the study period to 2 years of the pandemic. The longer time frame helps address potential seasonal differences in incidence and increases confidence in the results.

The investigators also sought to look at the incidence of type 2 diabetes in children but found few studies that met the study criteria. Although some studies reported rates of type 2 diabetes, most lacked information about the population, specifically, the “denominator” needed for findings regarding any association with the COVID-19 pandemic.

SAN DIEGO – Should pharmacologic treatment of type 2 diabetes start with combination therapy or metformin monotherapy, adding other agents over time?

This question was debated by two well-known clinician-researchers in the diabetes world at the recent annual scientific sessions of the American Diabetes Association.

Ralph A. DeFronzo, MD, argued for combination therapy at the time of diagnosis, and David M. Nathan, MD, countered that sequential therapy is a better way to go.
 

‘The ominous octet’: Addressing multiple underlying defects

Of course, Dr. DeFronzo said, the right agents must be selected. “The drugs we’re going to use as combination at a minimum have to correct the underlying insulin resistance and beta-cell failure, or we are not going to be successful.”

In addition, he said, these drugs should also provide protection against cardiovascular, kidney, and fatty liver disease, because “[managing] diabetes is more than just controlling the glucose.”

Recent U.S. data suggest that half of people with diabetes have a hemoglobin A1c above 7%, and a quarter remain above 8%. “We’re not really doing a very good job in terms of glycemic control,” said Dr. DeFronzo, chief of the diabetes division at University of Texas, San Antonio.

One reason for this failure, he said, is the complex pathophysiology of type 2 diabetes represented by eight major defects, what he called the “ominous octet”: decreased pancreatic insulin secretion, gut incretin effects, glucose uptake in the muscle, increased lipolysis, glucose reabsorption in the kidney, hepatic glucose production, increased glucagon secretion, and neurotransmitter dysfunction.

“There are eight problems, so you’re going to need multiple drugs in combination ... not ones that just lower the A1c.”

And, Dr. DeFronzo said, these drugs “must be started early in the natural history of type 2 diabetes if progressive beta-cell failure is to be prevented.”

He pointed to the United Kingdom Prospective Diabetes Study (UKPDS), in which the sulfonylurea glyburide was used first, followed by metformin. With each drug, the A1c decreased initially but then rose within 3 years. By 15 years, 65% of participants were taking insulin.

More recently, the GRADE study examined the effects of adding four different glucose-lowering agents (glimepiride, sitagliptin, liraglutide, or insulin glargine) in people who hadn’t achieved target A1c with metformin.

“So, by definition, drug number one failed,” he observed.

During the study, all participants showed an initial A1c drop, followed by progressive failure, “again ... showing that stepwise therapy doesn’t work.”

All patients with type 2 diabetes at his center are treated using the “DeFronzo algorithm” consisting of three drug classes: a glucagon-like peptide-1 (GLP-1) agonist, a sodium-glucose cotransporter-2 (SGLT2) inhibitor, and pioglitazone, as each of them targets more than one of the “ominous octet” defects.

“The drugs that clearly do not work on a long-term basis are metformin and sulfonylureas,” he emphasized.

Several studies demonstrate the efficacy of combination therapy, he said. In one, DURATION 8, the combination of exenatide and dapagliflozin was superior to either agent individually in lowering A1c, cardiovascular events, and all-cause mortality over 2 years.

And in the 5-year VERIFY study, early combination therapy with vildagliptin plus metformin proved superior in A1c-lowering to starting patients on metformin and adding vildagliptin later.

Dr. DeFronzo’s own “knock-out punch” study, EDICT, in people with new-onset type 2 diabetes, compared the initial combination of metformin, pioglitazone, and exenatide with conventional sequential add-on therapy with metformin, glipizide, and insulin glargine.

The primary endpoint – the difference in the proportion of patients with A1c less than 6.5% – was 70% versus 29% with combination compared with sequential therapy, a difference “as robust as you can be going against the stepwise approach” at P < .00001, he said.

The combination therapy virtually normalized both insulin sensitivity and beta-cell function, whereas the conventional therapy did neither.

Also from Dr. DeFronzo’s group, in the Qatar study, which compared exenatide plus pioglitazone with basal-bolus insulin in people with about 10 years’ duration of type 2 diabetes and A1c above 7.5% taking sulfonylurea plus metformin, the combination therapy produced an A1c of 6.2% versus 7.1% with insulin.

Dr. DeFronzo pointed to new language added to the ADA Standards of Medical Care in Diabetes in 2022.

While still endorsing stepwise therapy, the document also says that “there are data to support initial combination therapy for more rapid attainment of glycemic targets and longer durability of glycemic effect.” The two references cited are EDICT and VERIFY.

“Finally, the American Diabetes Association has gotten the message,” he concluded.
 

Sequential therapy: Far more data, lower cost

Dr. Nathan began by pointing out that the ADA Standards of Care continue to advise use of metformin as first-line therapy for type 2 diabetes “because of its high efficacy in lowering A1c, minimal hypoglycemia risk when used as monotherapy, weight neutrality with the potential for modest weight loss, good safety profile, and low cost.”

He emphasized that he was not arguing “against the use of early or even initial combination therapy when there are co-existent morbidities [such as cardiovascular or chronic kidney disease] that merit use of demonstrably effective medications.” But Dr. Nathan pointed out, those patients are not the majority with type 2 diabetes.

He laid out four main arguments for choosing traditional sequential therapy over initial combination therapy. For one, it “enables determination of efficacy of adding individual medications, while initial combination precludes determining benefits of individual drugs.”

Second, traditional sequential therapy allows for assessment of side effects from individual drugs.

“With Dr. DeFronzo’s algorithm you throw everything at them, and if they get nausea, vomiting, or diarrhea, you won’t know which drug it is ... If they get an allergic reaction, you won’t know which medication it is,” observed Dr. Nathan, who is director of the clinical research center and the diabetes center at Massachusetts General Hospital, Boston.

Moreover, he said, traditional sequential therapy “promotes individualization, with selection of drugs, which is something we’re laboring to achieve. Initial combination obviously limits that.”

Further, sequential therapy is “parsimonious and cost-effective, whereas initial combination therapy is expensive, with modest advantages at most.”

And, there are “lots of data” supporting traditional sequential therapy and relatively little for initial combination therapy.

Dr. Nathan added that when he searched the literature for relevant randomized clinical trials, he found 16 investigating initial combination therapy versus monotherapy, but only three that examined combination versus sequential therapy.

“Very few of them, except for EDICT and VERIFY, actually include the sequential therapy that we would use in practice,” he said.

Moreover, he observed, except for the VERIFY study, most are less than half a year in duration. And in VERIFY, there was an initial 20% difference in the proportions of patients with A1c below 7.0%, but by 12 months, that difference had shrunk to just 5%-6%.

“So, looking over time is very important,” Dr. Nathan cautioned. “We really have to be careful ... Six months is barely enough time to see A1c equilibrate ... You really need to study a long-term, chronic, progressive disease like type 2 diabetes over a long enough period of time to be clinically meaningful.”

Dr. Nathan acknowledged to Dr. DeFronzo that the latter’s EDICT study was “well conducted” and “long enough,” and that the researchers did examine monotherapy versus sequential therapy. However, he pointed out that it was a small study with 249 patients and the dropout rate was high, with 58% of patients remaining in the study with triple therapy versus 68% for conventional treatment. “That’s a bit problematic,” Dr. Nathan noted.

At 2 years, the “trivial” difference in A1c was 6.5% with conventional therapy versus 6.0% with triple therapy. “This is all on the very flat complications curve with regard to A1c,” he observed.

Patients treated with sequential therapy with sulfonylurea and insulin had higher rates of hypoglycemia and weight gain, whereas the combination triple therapy group had more gastrointestinal side effects and edema.

However, the most dramatic difference was cost: the average wholesale price for sequential therapy totaled about $85 per month, compared with $1,310 for initial combination therapy. For the approximately 1.5 million patients with new-onset type 2 diabetes in the United States, that difference comes to an additional cost per year of about $22 billion, Dr. Nathan calculated.

“Although current sequential therapy leaves much to be desired ... initial combination therapy has generally only been tested for brief, clinically insufficient periods.

“And therefore, I think sequential therapy is still what is called for,” he concluded. “Well-powered, acceptable-duration studies need to be performed before we can adopt initial/early combination therapy as the standard of care.”

Dr. DeFronzo has reported receiving research support from Boehringer Ingelheim, AstraZeneca, and Merck; payment or honoraria for lectures, presentations, speakers bureaus, manuscript writing, or educational events from AstraZeneca; and participation on a data safety monitoring board or advisory board for AstraZeneca, Intarcia, Novo Nordisk, and Boehringer Ingelheim. Dr. Nathan has reported no relevant financial relationships.

Several studies demonstrate the efficacy of combination therapy, he said. In one, DURATION 8, the combination of exenatide and dapagliflozin was superior to either agent individually in lowering A1c, cardiovascular events, and all-cause mortality over 2 years.

And in the 5-year VERIFY study, early combination therapy with vildagliptin plus metformin proved superior in A1c-lowering to starting patients on metformin and adding vildagliptin later.

Dr. DeFronzo’s own “knock-out punch” study, EDICT, in people with new-onset type 2 diabetes, compared the initial combination of metformin, pioglitazone, and exenatide with conventional sequential add-on therapy with metformin, glipizide, and insulin glargine.

The primary endpoint – the difference in the proportion of patients with A1c less than 6.5% – was 70% versus 29% with combination compared with sequential therapy, a difference “as robust as you can be going against the stepwise approach” at P < .00001, he said.

The combination therapy virtually normalized both insulin sensitivity and beta-cell function, whereas the conventional therapy did neither.

Also from Dr. DeFronzo’s group, in the Qatar study, which compared exenatide plus pioglitazone with basal-bolus insulin in people with about 10 years’ duration of type 2 diabetes and A1c above 7.5% taking sulfonylurea plus metformin, the combination therapy produced an A1c of 6.2% versus 7.1% with insulin.

Dr. DeFronzo pointed to new language added to the ADA Standards of Medical Care in Diabetes in 2022.

While still endorsing stepwise therapy, the document also says that “there are data to support initial combination therapy for more rapid attainment of glycemic targets and longer durability of glycemic effect.” The two references cited are EDICT and VERIFY.

“Finally, the American Diabetes Association has gotten the message,” he concluded.
 

Sequential therapy: Far more data, lower cost

Dr. Nathan began by pointing out that the ADA Standards of Care continue to advise use of metformin as first-line therapy for type 2 diabetes “because of its high efficacy in lowering A1c, minimal hypoglycemia risk when used as monotherapy, weight neutrality with the potential for modest weight loss, good safety profile, and low cost.”

He emphasized that he was not arguing “against the use of early or even initial combination therapy when there are co-existent morbidities [such as cardiovascular or chronic kidney disease] that merit use of demonstrably effective medications.” But Dr. Nathan pointed out, those patients are not the majority with type 2 diabetes.

He laid out four main arguments for choosing traditional sequential therapy over initial combination therapy. For one, it “enables determination of efficacy of adding individual medications, while initial combination precludes determining benefits of individual drugs.”

Second, traditional sequential therapy allows for assessment of side effects from individual drugs.

“With Dr. DeFronzo’s algorithm you throw everything at them, and if they get nausea, vomiting, or diarrhea, you won’t know which drug it is ... If they get an allergic reaction, you won’t know which medication it is,” observed Dr. Nathan, who is director of the clinical research center and the diabetes center at Massachusetts General Hospital, Boston.

Moreover, he said, traditional sequential therapy “promotes individualization, with selection of drugs, which is something we’re laboring to achieve. Initial combination obviously limits that.”

Further, sequential therapy is “parsimonious and cost-effective, whereas initial combination therapy is expensive, with modest advantages at most.”

And, there are “lots of data” supporting traditional sequential therapy and relatively little for initial combination therapy.

Dr. Nathan added that when he searched the literature for relevant randomized clinical trials, he found 16 investigating initial combination therapy versus monotherapy, but only three that examined combination versus sequential therapy.

“Very few of them, except for EDICT and VERIFY, actually include the sequential therapy that we would use in practice,” he said.

Moreover, he observed, except for the VERIFY study, most are less than half a year in duration. And in VERIFY, there was an initial 20% difference in the proportions of patients with A1c below 7.0%, but by 12 months, that difference had shrunk to just 5%-6%.

“So, looking over time is very important,” Dr. Nathan cautioned. “We really have to be careful ... Six months is barely enough time to see A1c equilibrate ... You really need to study a long-term, chronic, progressive disease like type 2 diabetes over a long enough period of time to be clinically meaningful.”

Dr. Nathan acknowledged to Dr. DeFronzo that the latter’s EDICT study was “well conducted” and “long enough,” and that the researchers did examine monotherapy versus sequential therapy. However, he pointed out that it was a small study with 249 patients and the dropout rate was high, with 58% of patients remaining in the study with triple therapy versus 68% for conventional treatment. “That’s a bit problematic,” Dr. Nathan noted.

At 2 years, the “trivial” difference in A1c was 6.5% with conventional therapy versus 6.0% with triple therapy. “This is all on the very flat complications curve with regard to A1c,” he observed.

Patients treated with sequential therapy with sulfonylurea and insulin had higher rates of hypoglycemia and weight gain, whereas the combination triple therapy group had more gastrointestinal side effects and edema.

However, the most dramatic difference was cost: the average wholesale price for sequential therapy totaled about $85 per month, compared with $1,310 for initial combination therapy. For the approximately 1.5 million patients with new-onset type 2 diabetes in the United States, that difference comes to an additional cost per year of about $22 billion, Dr. Nathan calculated.

“Although current sequential therapy leaves much to be desired ... initial combination therapy has generally only been tested for brief, clinically insufficient periods.

“And therefore, I think sequential therapy is still what is called for,” he concluded. “Well-powered, acceptable-duration studies need to be performed before we can adopt initial/early combination therapy as the standard of care.”

Dr. DeFronzo has reported receiving research support from Boehringer Ingelheim, AstraZeneca, and Merck; payment or honoraria for lectures, presentations, speakers bureaus, manuscript writing, or educational events from AstraZeneca; and participation on a data safety monitoring board or advisory board for AstraZeneca, Intarcia, Novo Nordisk, and Boehringer Ingelheim. Dr. Nathan has reported no relevant financial relationships.

Among adults with type 2 diabetes, the presence of preserved ratio impaired spirometry (PRISm) was significantly associated with increased risk of mortality and both macro- and microvascular complications, as well as increased mortality, based on data from more than 20,000 individuals.

PRISm occurs in approximately 10% of the general population and has been identified as a predictor of adverse health outcomes including cardiorespiratory morbidity and mortality, Guochen Li, MD, of the Medical College of Soochow University, Suzhou, China, and colleagues wrote.

“A growing number of studies have demonstrated that impaired lung function and type 2 diabetes could trigger shared pathophysiological injuries, such as microangiopathy and chronic inflammation,” they said, but the potential role of PRISm as an early predictor of adverse outcomes in patients with type 2 diabetes has not been fully examined.

In a study published in the journal Chest, the researchers reviewed data from 20,047 individuals with type 2 diabetes in the UK Biobank, a population-based cohort of adults aged 37-73 years recruited between 2006 and 2010.

The main exposure was lung function based on spirometry. PRISm was defined as predicted forced expiratory volume per second (FEV1) less than 80%, with an FEV1/ forced vital capacity (FVC) ratio of at least 0.70. Individuals with normal spirometry (defined as predicted FEV1 ≥ 80% with an FEV1/FVC ratio ≥ 0.70) served as controls.

The primary outcomes were major complications of type 2 diabetes including macrovascular events (myocardial infarction, unstable angina, coronary heart disease [CHD], ischemic stroke, and any type of stroke), microvascular events (diabetic retinopathy and diabetic kidney disease) and mortality (all-cause, cardiovascular, and respiratory).

Overall, 16.9% of study participants (3385 patients) had obstructive spirometry and 22.6% (4521 patients) had PRISm. Compared with individuals with normal spirometry, those with PRISm were more likely to be current smokers, obese, and living in economically disadvantaged areas. Individuals with PRISm also were significantly more likely to be long-term patients with diabetes who were taking glucose-lowering or lipid-lowering drugs (P < .001 for all).

The median follow-up for each of the type 2 diabetes complications and mortality was approximately 12 years. Over this time, 5.0% of patients developed incident MI, 1.3% developed unstable angina, 15.6% had CHD, 3.5% had an ischemic stroke, and 4.7% had any type of stroke. As for microvascular events, 7.8% developed diabetic retinopathy and 6.7% developed diabetic kidney disease. A total of 2588 patients died during the study period (15.1%), including 544 from cardiovascular disease and 319 from respiratory disease.

PRISm was significantly associated with increased risk of each of the complications and mortality types. These associations persisted after adjusting for lifestyle and other factors. The fully adjusted hazard ratios for PRISm versus normal spirometry were 1.23 for MI, 1.23 for unstable angina, 1.21 for CHD, 1.38 for ischemic stroke, 1.41 for any type of stroke, 1.31 for diabetic retinopathy, and 1.38 for diabetic kidney disease. Adjusted HRs for mortality were 1.34, 1.60, and 1.56 for all-cause, cardiovascular, and respiratory mortality, respectively.

The researchers also found that adding PRISm to an office-based risk score significantly improved the risk classification and predictive power for type 2 diabetes complications with the exception of unstable angina and mortality. They found little evidence for an association with sex, smoking, or PRISm duration and any mortality types. However, in subgroup analyses by age, sex, and duration of diabetes, PRISm remained associated with increased risk of macrovascular and microvascular complications, as well as mortality.

Potential mechanisms for the association between PRISm and diabetes complications include the role of insulin resistance in the exacerbation of lung damage in patients with type 2 diabetes, the increased rate of supplemental oxygen use among individuals with PRISm, and the increased prevalence of pulmonary artery enlargement in the PRISm subjects, the researchers wrote.

The findings were limited by several factors including the prospective design, the homogeneous population of individuals primarily of British or Irish ancestry, and the exclusion of diabetic neuropathy from the analysis, the researchers noted.

However, the results were strengthened by the large cohort, use of professional spirometry, and relatively long follow-up. “The findings underscore the relevance of PRISm for prognostic classification in type 2 diabetes and its potential for optimizing prevention strategies in this condition,” they concluded.

The study was supported by the National Natural Science Foundation of China, Natural Science Foundation of Jiangsu Province, and the Priority Academic Program Development of Jiangsu Higher Education Institutions. The researchers reported no relevant financial relationships.

Following reports that the European Medicines Agency is looking into instances of suicide or self-harm after patients took the weight loss drugs semaglutide or liraglutide, the manufacturer, Novo Nordisk, issued a statement to this news organization in which it says it “remains confident in the benefit risk profile of the products and remains committed to ensuring patient safety.”

U.S. experts say they haven’t personally seen this adverse effect in any patients except for one isolated case. An increase in suicidal ideation, particularly among younger people, has been reported following bariatric surgery for weight loss.

In the United States, the two drugs – both GLP-1 agonists – already come with a warning about the potential for these adverse effects on the branded versions approved for weight loss, Wegovy and Saxenda. (Years earlier, both drugs, marketed as Ozempic and Victoza, were also approved for treatment of type 2 diabetes.)

Of more than 1,200 reports of adverse reactions with semaglutide, 60 cases of suicidal ideation and 7 suicide attempts have been reported since 2018, according to the Food and Drug Administration’s Adverse Event Reporting System (FAERS) public database. For liraglutide, there were 71 cases of suicidal ideation, 28 suicide attempts, and 25 completed suicides out of more than 35,000 reports of adverse reactions.

The FAERS website cautions users that the data may be duplicated or incomplete, that rates of occurrence cannot be established using the data, that reports have not been verified, and that the existence of a report cannot establish causation.

The EMA is looking into about 150 reports of possible cases of self-injury and suicidal thoughts, according to a press release from the agency.

“It is not yet clear whether the reported cases are linked to the medicines themselves or to the patients’ underlying conditions or other factors,” it says. The medicines are widely used in the European Union, according to the press release.

The review of Ozempic, Saxenda, and Wegovy, which started on July 3, 2023, has been extended to include other GLP-1 receptor agonists, which include dulaglutide, exenatide, and lixisenatide. This review is expected to conclude in November 2023.

In a statement, Novo Nordisk did not directly dispute a potential link between the drugs and suicidal ideation.

“In the U.S., FDA requires medications for chronic weight management that work on the central nervous system, including Wegovy and Saxenda, to carry a warning about suicidal behavior and ideation,” the statement indicates. “This event had been reported in clinical trials with other weight management products.”

It adds: “Novo Nordisk is continuously performing surveillance of the data from ongoing clinical trials and real-world use of its products and collaborates closely with the authorities to ensure patient safety and adequate information to healthcare professionals.”
 

Important to know the denominator

“What’s important to know is the denominator,” said Holly Lofton, MD, a clinical associate professor of surgery and medicine and the director of the medical weight management program at NYU Langone, New York. “It needs a denominator with the total population on the medication so we can determine if that’s really a significant risk.”

Dr. Lofton described an isolated, anecdotal case of a patient who had no history of depression or mental health problems but developed suicidal thoughts after taking Saxenda for several months. In that case, the 25-year-old was experiencing problems in a personal relationship and with social media.

Two other weight loss specialists contacted by this news organization had not had patients who had experienced suicidal ideation with the drugs. “These are not very common in practice,” Dr. Lofton said in an interview.

The U.S. prescribing information for Saxenda, which contains liraglutide and has been approved as an adjunct to diet and exercise for chronic weight management, recommends monitoring for the emergence of depression and suicidal thoughts. In the clinical trials, 6 of the 3,384 patients who took the drug reported suicidal ideation; none of the 1,941 patients who received placebo did so, according to the FDA.

Similarly, the U.S. prescribing information for Wegovy, which contains semaglutide, recommends monitoring for the emergence of suicidal thoughts or depression, but this recommendation was based on clinical trials of other weight management products. The prescribing information for Ozempic, the brand name for semaglutide for type 2 diabetes, does not include this recommendation.
 

Is it the weight loss, rather than the meds? Seen with bariatric surgery too

Speculating what the link, if any, might be, Dr. Lofton suggested dopamine release could be playing a role. Small trials in humans as well as animal studies hint at a blunting of dopamine responses to usual triggers – including addictive substances and possibly food – that may also affect mood.

Young people (aged 18-34) who undergo bariatric surgery are at an increased risk of suicide during follow-up compared to their peers who don’t have surgery. And a study found an increase in events involving self-harm after bariatric surgery, especially among patients who already had a mental health disorder.

For a patient who derives comfort from food, not being able to eat in response to a stressful event may lead that patient to act out in more serious ways, according to Dr. Lofton. “That’s why, again, surgical follow-up is so important and their presurgical psychiatric evaluation is so important.”

The review of Ozempic, Saxenda, and Wegovy, which started on July 3, 2023, has been extended to include other GLP-1 receptor agonists, which include dulaglutide, exenatide, and lixisenatide. This review is expected to conclude in November 2023.

In a statement, Novo Nordisk did not directly dispute a potential link between the drugs and suicidal ideation.

“In the U.S., FDA requires medications for chronic weight management that work on the central nervous system, including Wegovy and Saxenda, to carry a warning about suicidal behavior and ideation,” the statement indicates. “This event had been reported in clinical trials with other weight management products.”

It adds: “Novo Nordisk is continuously performing surveillance of the data from ongoing clinical trials and real-world use of its products and collaborates closely with the authorities to ensure patient safety and adequate information to healthcare professionals.”
 

Important to know the denominator

“What’s important to know is the denominator,” said Holly Lofton, MD, a clinical associate professor of surgery and medicine and the director of the medical weight management program at NYU Langone, New York. “It needs a denominator with the total population on the medication so we can determine if that’s really a significant risk.”

Dr. Lofton described an isolated, anecdotal case of a patient who had no history of depression or mental health problems but developed suicidal thoughts after taking Saxenda for several months. In that case, the 25-year-old was experiencing problems in a personal relationship and with social media.

Two other weight loss specialists contacted by this news organization had not had patients who had experienced suicidal ideation with the drugs. “These are not very common in practice,” Dr. Lofton said in an interview.

The U.S. prescribing information for Saxenda, which contains liraglutide and has been approved as an adjunct to diet and exercise for chronic weight management, recommends monitoring for the emergence of depression and suicidal thoughts. In the clinical trials, 6 of the 3,384 patients who took the drug reported suicidal ideation; none of the 1,941 patients who received placebo did so, according to the FDA.

Similarly, the U.S. prescribing information for Wegovy, which contains semaglutide, recommends monitoring for the emergence of suicidal thoughts or depression, but this recommendation was based on clinical trials of other weight management products. The prescribing information for Ozempic, the brand name for semaglutide for type 2 diabetes, does not include this recommendation.
 

Is it the weight loss, rather than the meds? Seen with bariatric surgery too

Speculating what the link, if any, might be, Dr. Lofton suggested dopamine release could be playing a role. Small trials in humans as well as animal studies hint at a blunting of dopamine responses to usual triggers – including addictive substances and possibly food – that may also affect mood.

Young people (aged 18-34) who undergo bariatric surgery are at an increased risk of suicide during follow-up compared to their peers who don’t have surgery. And a study found an increase in events involving self-harm after bariatric surgery, especially among patients who already had a mental health disorder.

For a patient who derives comfort from food, not being able to eat in response to a stressful event may lead that patient to act out in more serious ways, according to Dr. Lofton. “That’s why, again, surgical follow-up is so important and their presurgical psychiatric evaluation is so important.”

The Food and Drug Administration has cleared the Tandem Mobi insulin pump for people with diabetes aged 6 years or older.

The product is half the size of the company’s t:slim X2 and is now the smallest of the commercially available durable tubed pumps. It is fully controllable from a mobile app through a user’s compatible iPhone.

Features of the Mobi include a 200-unit insulin cartridge and an on-pump button that can be used instead of the phone for bolusing insulin. The device can be clipped to clothing or worn on-body with an adhesive sleeve that is sold separately.

The Mobi is compatible with all existing Tandem-branded infusion sets manufactured by the Convatec Group, and there is a new 5-inch tubing option made just for the Tandem Mobi.

The Mobi is part of a hybrid-closed loop automated delivery system, along with the current Control-IQ technology and a compatible continuous glucose monitor (CGM). The CGM sensor predicts glucose values 30 minutes ahead and adjusts insulin delivery every 5 minutes to prevent highs and lows. Users must still manually bolus for meals. The system can deliver automatic correction boluses for up to 1 hour to prevent hyperglycemia.

Limited release of the Tandem Mobi is expected in late 2023, followed by full commercial availability in early 2024.

Findings from a recent study indicate that the less U.S. patients pay out of pocket for drugs that often have high co-pays, such as sodium-glucose cotransporter 2 (SGLT2) inhibitors or glucagonlike peptide-1 (GLP-1) agonists, the more they adhere to taking these medications.

The study, led by Utibe R. Essien, MD, from University of California, Los Angeles, and Balvindar Singh, MD, PhD, from University of Pittsburgh, was published online in JAMA Cardiology.

Patient data from Clinformatics Data Mart, a health insurance claims database, was analyzed for the study. The information for 90,041 adults from the United States who had commercial and Medicare health insurance, and who started taking a GLP-1 agonist or SGLT2 inhibitor between 2014 and 2020 was reviewed. Participants had type 2 diabetes, heart failure, or both.

The primary outcome showed patients with a lower drug co-pay had significantly higher odds of 12-month adherence to GLP-1 agonists and SGLT2 inhibitors, compared with those with a higher co-pay. These differences persisted after controlling for patient demographic, clinical, and socioeconomic covariates.

After full adjustments were made and after the 12 months, patients with a high co-pay of $50 per month or more were 53% less likely to adhere to an SGLT2 inhibitor and 32% less likely to adhere to a GLP-1 agonist, compared with patients with a co-pay of less than $10 per month for these agents.

“Lowering high out-of-pocket prescription costs may be key to improving adherence to guideline-recommended therapies and advancing overall quality of care in patients with type 2 diabetes and heart failure,” the authors conclude.

The authors acknowledge the study’s limitations, including the inability to exclude residual confounding, uncertain generalizability for those without health insurance or with public insurance and possible misclassifications of type 2 diabetes and heart failure diagnoses or medical comorbidities. Additionally, this study did not have information on patients’ preferences associated with medication use, including specific reasons for poor adherence, and could not assess how co-payments influenced initial prescription receipt or abandonment at the pharmacy, or other factors including possible price inflation.

The study received no commercial funding. One author (not a lead author) is an adviser to several drug companies including ones that market SGLT2 inhibitors or GLP-1 agonists.

A smartphone-based app designed to deliver cognitive-behavioral therapy (CBT) to adults with type 2 diabetes received marketing approval as a class II medical device from the Food and Drug Administration on July 10, becoming the first digital behavioral therapeutic device for people with diabetes to receive this designation for U.S. patients.
 

Better Therapeutics representatives said that the app, formerly known as BT-001, will be called AspyreRX, with U.S. sales planned to launch in October-December 2023.

The app will be available to patients exclusively by prescription, with a planned 90-day use duration and an option for a second 90-day prescription. A company official said the price per prescription will be about $500-800, although this is not yet finalized. The app is intended for use in concert with the conventional pillars of glycemic control in people with type 2 diabetes: lifestyle modification and treatment with antidiabetes medications.

Senior staff members of Better Therapeutics acknowledged the critical need for an education program, which they will now launch for clinicians, payers, and patients to get across the message of the potential benefit and safety associated with using the CBT app. Their initial marketing will target patients with type 2 diabetes and poorly controlled hemoglobin A1c levels in five to six U.S. regions with high numbers of these patients. The company will also attempt to make the app available through the Department of Veterans Affairs health system and try to secure coverage by Medicare and commercial health-insurance providers.
 

Approval based on pivotal trial results

The FDA approval focused on data collected in the BT-001 randomized, controlled trial, which included 669 U.S. adults with poorly controlled type 2 diabetes. Results, published in 2022 in Diabetes Care, showed that after 90 days, people using the app had an average incremental reduction in A1c of 0.39 percentage points, compared with control patients who didn’t use the app, the primary endpoint. Use of the app also appeared safe.

Subsequent meeting presentations of study findings showed that A1c-lowering linked with app use was durable during continued use for a total of 180 days, that the effectiveness of the app in helping to lower A1c levels was “dose dependent” relative to the number of lessons a person completed, and that using the app significantly linked with a reduced need for intensified glycemic control through added medications.

Another finding of the extended-use phase of the study was that 81% of patients assigned to the app-using group continued to regularly use the app after 180 days, a level of durable engagement by patients that “exceeded our expectations,” said Diane Gomez-Thinnes, chief commercial officer of Better Therapeutics, during a press conference.

The company plans to tweak the app prior to its launch based on additional analyses of results from the pivotal study to further improve patient engagement and app ease of use. The company is also planning to expand the range of smartphones that can support the app, although about 90%-95% of U.S. smartphones have this capability.

Better Therapeutics is also actively developing and testing other modifications to the basic CBT app to make it usable by people with other cardiometabolic disorders such as hypertension, obesity, and fatty liver disease.

SAN DIEGO – The landmark Diabetes Control and Complications Trial (DCCT) follow-up study has entered a new phase, focusing on a relatively recent phenomenon: aging in type 1 diabetes.

New funding for 2022-2027 for the DCCT long-term observational follow-up study, the Epidemiology of Diabetes Interventions and Complications (EDIC) will go toward investigating aspects of type 1 diabetes that are associated with aging and are also common in type 2 diabetes, including cardiovascular disease, fatty liver disease, and sleep apnea.

The original randomized DCCT clinical trial results, published in 1993 in the New England Journal of Medicine, proved that early intensive glycemic control was the key to preventing or slowing the progression of long-term eye, kidney, and nerve complications of type 1 diabetes. Subsequently, EDIC has yielded many more major findings including that early tight glycemic control also reduces cardiovascular risk and prolongs survival in type 1 diabetes.

And although the phenomenon of metabolic memory initially seen in EDIC means that early glycemic control is important, subsequent EDIC data also have suggested that it is never too late to initiate intensive glycemic control, speakers emphasized during a special symposium commemorating 40 years since the start of DCCT, held during the annual scientific sessions of the American Diabetes Association. As with the 30-year DCCT/EDIC commemorative symposium held in 2013, local study participants were in the audience and were acknowledged with long applause.

Together, DCCT and EDIC – both funded by the National Institutes of Health at 27 sites in the United States and Canada – have changed the standard of care for people with type 1 diabetes and continue to inform clinical practice. Prior to the DCCT, between 1930 and 1970, about a third of people with type 1 diabetes developed vision loss and one in five experienced kidney failure and/or myocardial infarction. Stroke and amputation were also common, DCCT/EDIC chair David M. Nathan, MD, said while introducing the symposium.

“All of the advances in care of type 1 diabetes have developed because this study demonstrated that it was important – continuous glucose monitoring (CGM), new insulins, better [insulin] pumps. ... I think the most profound finding is that mortality in our intensively treated cohort is the same as in the general population. That says it all,” Dr. Nathan said in an interview.

And now, “what we still have yet to contribute is what happens to type 1 diabetes as people get older,” added Dr. Nathan, a professor of medicine at Harvard Medical School and director of the Diabetes Center at Massachusetts General Hospital, both in Boston.
 

‘Something that heretofore none of us could have imagined’

The 1,441 DCCT participants had a mean age of 27 years at baseline in 1983, when they were randomized to intensive insulin therapy or usual care. The 1,375 participants (96%) who continued into EDIC in 1994 were an average of 35 years old at that point, when the usual care group was taught intensive glycemic management and all participants returned to their personal health care teams. The 1,075 participants in EDIC today are an average age of 63 years.

Only 11 participants had died at the start of EDIC, and just 250 (17%) have died as of 2023, said study coordinator cochair Gayle Lorenzi, RN, who is a certified diabetes care and education specialist at the University of California, San Diego.

“DCCT/EDIC because of its longevity represents a unique opportunity to explore aging in long duration of type 1 diabetes, something that heretofore none of us could have imagined, especially for those of you in the audience who started your careers in the 70s and 80s,” Ms. Lorenzi commented.

About 36% of the cohort now has overweight and 40% have obesity, mirroring the general population. And they now have a mean hemoglobin A1c of 7.3%.

According to Barbara H. Braffett, PhD, co–principal investigator at the DCCT/EDIC data coordinating center: “The EDIC study is now shifting its focus during the next 5 years to understand the clinical course of type 1 diabetes in the setting of advancing duration and age, as well as increasing adiposity, which has progressively affected individuals with type 1 diabetes and has potential long-term adverse consequences.”

Dr. Braffett outlined the new study approaches added in 2022-2027. Cardiopulmonary exercise testing, two-dimensional Doppler echocardiography, and carotid-femoral pulse wave velocity will be used to quantify functional and structural changes central to heart failure.

Dr. Nathan commented that, although enough cardiovascular events were available in EDIC by 2006 to demonstrate a significant 58% reduction in the intensive therapy group, “now we can start looking at the aging heart. We have a bunch of great cardiologists working with us who will be guiding us on measuring everything.”

Fatty liver disease in the setting of increasing adiposity will also be investigated using transient elastography (FibroScan) and the Fibrosis-4 index, a quantification of liver enzymes and platelet count.

Dr. Nathan noted that the study participants have had “this kind of funny metabolic milieu in their liver for decades. They don’t make insulin in their pancreas, and therefore, the insulin they get is peripheral and then it goes to their liver. Well, what does that do to them?”

Participants will also complete three symptom questionnaires assessing obstructive sleep apnea, aimed at guiding future sleep studies in those found to be at high risk, Dr. Braffett said.
 

DCCT/EDIC over 40 years: ‘Incredibly complete picture’

As of 2023, the DCCT/EDIC participants have been studied for longer than 60% of their lifespans and for over 80% of their diabetes duration, Dr. Braffett noted.

During the EDIC 2017-2022 cycle, Dr. Braffett and other speakers summarized, prior EDIC efforts had focused on aspects of cognitive function, physical function, and cheiroarthropathy.

Other DCCT/EDIC studies examined the relationship of A1c and diabetes duration in cardiovascular disease risk, the association of microvascular complications with the risk of cardiovascular disease beyond traditional risk factors, and the risk of severe hypoglycemia over the first 30 years of DCCT/EDIC follow-up.

Moreover, the longitudinal eye and kidney assessments over the 40 years have informed screening guidelines for retinopathy and urinary albumin.

Dr. Nathan said: “Today, the number with horrible complications is very few, but we haven’t erased complications entirely. ... We have this incredibly complete picture of type 1 diabetes that allows us to explore everything. We welcome people to come to us with ideas. That’s the value of this research.”

Dr. Nathan, Ms. Lorenzi, and Dr. Braffett reported no relevant financial relationships.

Only 11 participants had died at the start of EDIC, and just 250 (17%) have died as of 2023, said study coordinator cochair Gayle Lorenzi, RN, who is a certified diabetes care and education specialist at the University of California, San Diego.

“DCCT/EDIC because of its longevity represents a unique opportunity to explore aging in long duration of type 1 diabetes, something that heretofore none of us could have imagined, especially for those of you in the audience who started your careers in the 70s and 80s,” Ms. Lorenzi commented.

About 36% of the cohort now has overweight and 40% have obesity, mirroring the general population. And they now have a mean hemoglobin A1c of 7.3%.

According to Barbara H. Braffett, PhD, co–principal investigator at the DCCT/EDIC data coordinating center: “The EDIC study is now shifting its focus during the next 5 years to understand the clinical course of type 1 diabetes in the setting of advancing duration and age, as well as increasing adiposity, which has progressively affected individuals with type 1 diabetes and has potential long-term adverse consequences.”

Dr. Braffett outlined the new study approaches added in 2022-2027. Cardiopulmonary exercise testing, two-dimensional Doppler echocardiography, and carotid-femoral pulse wave velocity will be used to quantify functional and structural changes central to heart failure.

Dr. Nathan commented that, although enough cardiovascular events were available in EDIC by 2006 to demonstrate a significant 58% reduction in the intensive therapy group, “now we can start looking at the aging heart. We have a bunch of great cardiologists working with us who will be guiding us on measuring everything.”

Fatty liver disease in the setting of increasing adiposity will also be investigated using transient elastography (FibroScan) and the Fibrosis-4 index, a quantification of liver enzymes and platelet count.

Dr. Nathan noted that the study participants have had “this kind of funny metabolic milieu in their liver for decades. They don’t make insulin in their pancreas, and therefore, the insulin they get is peripheral and then it goes to their liver. Well, what does that do to them?”

Participants will also complete three symptom questionnaires assessing obstructive sleep apnea, aimed at guiding future sleep studies in those found to be at high risk, Dr. Braffett said.
 

DCCT/EDIC over 40 years: ‘Incredibly complete picture’

As of 2023, the DCCT/EDIC participants have been studied for longer than 60% of their lifespans and for over 80% of their diabetes duration, Dr. Braffett noted.

During the EDIC 2017-2022 cycle, Dr. Braffett and other speakers summarized, prior EDIC efforts had focused on aspects of cognitive function, physical function, and cheiroarthropathy.

Other DCCT/EDIC studies examined the relationship of A1c and diabetes duration in cardiovascular disease risk, the association of microvascular complications with the risk of cardiovascular disease beyond traditional risk factors, and the risk of severe hypoglycemia over the first 30 years of DCCT/EDIC follow-up.

Moreover, the longitudinal eye and kidney assessments over the 40 years have informed screening guidelines for retinopathy and urinary albumin.

Dr. Nathan said: “Today, the number with horrible complications is very few, but we haven’t erased complications entirely. ... We have this incredibly complete picture of type 1 diabetes that allows us to explore everything. We welcome people to come to us with ideas. That’s the value of this research.”

Dr. Nathan, Ms. Lorenzi, and Dr. Braffett reported no relevant financial relationships.

SAN DIEGO – The landmark Diabetes Control and Complications Trial (DCCT) follow-up study has entered a new phase, focusing on a relatively recent phenomenon: aging in type 1 diabetes.

New funding for 2022-2027 for the DCCT long-term observational follow-up study, the Epidemiology of Diabetes Interventions and Complications (EDIC) will go toward investigating aspects of type 1 diabetes that are associated with aging and are also common in type 2 diabetes, including cardiovascular disease, fatty liver disease, and sleep apnea.

The original randomized DCCT clinical trial results, published in 1993 in the New England Journal of Medicine, proved that early intensive glycemic control was the key to preventing or slowing the progression of long-term eye, kidney, and nerve complications of type 1 diabetes. Subsequently, EDIC has yielded many more major findings including that early tight glycemic control also reduces cardiovascular risk and prolongs survival in type 1 diabetes.

And although the phenomenon of metabolic memory initially seen in EDIC means that early glycemic control is important, subsequent EDIC data also have suggested that it is never too late to initiate intensive glycemic control, speakers emphasized during a special symposium commemorating 40 years since the start of DCCT, held during the annual scientific sessions of the American Diabetes Association. As with the 30-year DCCT/EDIC commemorative symposium held in 2013, local study participants were in the audience and were acknowledged with long applause.

Together, DCCT and EDIC – both funded by the National Institutes of Health at 27 sites in the United States and Canada – have changed the standard of care for people with type 1 diabetes and continue to inform clinical practice. Prior to the DCCT, between 1930 and 1970, about a third of people with type 1 diabetes developed vision loss and one in five experienced kidney failure and/or myocardial infarction. Stroke and amputation were also common, DCCT/EDIC chair David M. Nathan, MD, said while introducing the symposium.

“All of the advances in care of type 1 diabetes have developed because this study demonstrated that it was important – continuous glucose monitoring (CGM), new insulins, better [insulin] pumps. ... I think the most profound finding is that mortality in our intensively treated cohort is the same as in the general population. That says it all,” Dr. Nathan said in an interview.

And now, “what we still have yet to contribute is what happens to type 1 diabetes as people get older,” added Dr. Nathan, a professor of medicine at Harvard Medical School and director of the Diabetes Center at Massachusetts General Hospital, both in Boston.
 

‘Something that heretofore none of us could have imagined’

The 1,441 DCCT participants had a mean age of 27 years at baseline in 1983, when they were randomized to intensive insulin therapy or usual care. The 1,375 participants (96%) who continued into EDIC in 1994 were an average of 35 years old at that point, when the usual care group was taught intensive glycemic management and all participants returned to their personal health care teams. The 1,075 participants in EDIC today are an average age of 63 years.

Only 11 participants had died at the start of EDIC, and just 250 (17%) have died as of 2023, said study coordinator cochair Gayle Lorenzi, RN, who is a certified diabetes care and education specialist at the University of California, San Diego.

A teenager who weighed 300 lb and was homeschooled because he was too big to fit in a classroom chair is among the patients Manal Habib, MD, has seen in her pediatric endocrinology practice.

The boy, a social butterfly who hated isolation and blamed himself for his “poor choices,” turned out to have an MC4R mutation that interfered with proper metabolism and satiation signals.

“People often blame obese and overweight people for not having enough willpower, but it’s often a physiological problem,” said Dr. Habib, who works at the University of California, Los Angeles.

She is among the clinicians offering more aggressive forms of weight management, prescribing medications, including metformin, semaglutide, and liraglutide – often off-label – to help children and teens with obesity who do not respond to lifestyle changes.

The results of intensive interventions can be life-changing: The teen Dr. Habib treated is back at school, playing sports, and no longer needs drugs to reduce cholesterol and blood pressure. He now takes a low maintenance dose of a weight-loss medication.

But the long-term effects of these new agents on children and teens are poorly understood, and both medication and surgery are associated with significant complications. Pediatricians treating kids pre- or post-intervention should be alert to a range of physical, psychological, and behavioral risks and complications.
 

Keeping bones healthy

Pediatricians should be aware of the risk to bone health in patients who undergo surgery, according to Misra Madhusmita, MD, chief of pediatric endocrinology at Massachusetts General Hospital in Boston. In a recent study, Dr. Madhusmita and her colleagues found that sleeve gastrectomy reduced vertebral bone strength in adolescents and young adults.

“This is a time of life when bone mass is typically accruing rapidly,” Dr. Madhusmita told this news organization. “A deleterious effect on bone accrual at this time of life raises concerns about suboptimal acquisition of peak bone mass, which is typically attained in early adult life and is a key factor determining bone health and fracture risk in later life.”

Reduced skeletal loading and muscle mass can weaken bones, as can malabsorption of nutrients. Fat loss can trigger lower levels of bioavailable androgens and their subsequent conversion to estrogen, negatively affecting bone density. And sleeve gastrectomy in particular lowers ghrelin, another hormone influencing skeletal health.

Clinicians should advise patients who have had surgery to follow a healthy diet and consume sufficient levels of calcium and vitamin D, said Dr. Madhusmita. Weight-bearing exercises, weight training, and resistance training are also imperative to build bone mass and muscle. Any preexisting conditions or lifestyle factors that weaken the bones should be taken into consideration.
 

Managing expectations

The long-term effects of weight loss medications on children are less documented than with surgery, according to Caren Mangarelli, MD, a former primary care physician who is now medical director of both the adolescent bariatric program and the children’s wellness and weight management clinic at Lurie Children’s Hospital in Chicago, Ill.

But one significant known risk is the potential for rebound weight gain and the complications like high blood pressure and high blood sugar that go with it if the patient stops medication. Dr. Mangarelli said that many clinicians lack the training required to safely facilitate weight loss medications for kids.

“We have to remember that obesity is a chronic disease, especially for those with more severe forms,” she said. “They’re not likely to outgrow it. It’s not like, ‘Oh, we’ll just put a patient on medication, they’ll lose weight, and we’ll take them off of it,’ because you could create a bad cycle of losing weight, followed by metabolism slowing down, hunger cues going up, and weight going back up.”

Making the risks of stopping medication clear and supporting compliance are essential, especially when it comes to injectables like semaglutide, which can be more burdensome than taking pills, requiring weekly subcutaneous injections. Pediatricians should ensure that families understand that medication is a long-term solution, Dr. Habib said.

Many families and patients “want a quick result. They’re focused on a specific size or weight, and they want to take the medication for a short period without changing anything else,” Dr. Habib said.

But children with genetic abnormalities or severe obesity could be on medication for their entire lives. Patients who make significant healthy lifestyle changes have a greater chance of weaning off drug therapy.

But “it’s hard with children because they’re dependent on their family,” Dr. Habib said. “One of the first things that I talk about with families is that it’s very important for everyone to be involved in making healthy changes, especially the parents, because the kids are going to follow their lifestyle and choices, not necessarily what they tell them to do.”
 

The behavioral and mental

One of Dr. Habib’s most striking cases was a 6-year-old patient with autism spectrum disorder experiencing early-onset puberty. Her condition made it difficult for her parents to enforce behavioral and lifestyle changes, making medication the best option to normalize the young girl’s body.

“The goal in this case is not necessarily to help her lose weight, but to prevent her from having severe health risks at such a young age,” said Habib.

Though medication may be the best solution when other options have failed, the ease of using medication may mean clinicians fail to address the complex emotional and psychosocial factors that can both cause and result from obesity.

“A lot of families think that if just this one thing were better, everything else would fall into place,” Habib said. “But there often are multiple layers to treating the patient.”

According to Cambria Garrell, MD, a pediatrician at the UCLA Fit for Healthy Weight Program in Los Angeles, pediatricians should be aware of the psychosocial and mental health factors such as undiagnosed mental illness or family dysfunction.

Dr. Garrell sometimes cares for children with undiagnosed mental health disorders. Children with conditions like attention-deficit/hyperactivity disorder and autism spectrum disorders may struggle with eating because of impulse control and sensory processing issues. Family functioning, issues at school, and lack of sleep are also major contributors to obesity to screen for.

“We really like to think about the environmental and psychosocial factors contributing to obesity instead of just pathologizing the weight,” Dr. Garrell said.
 

Risk for alcohol abuse

Bariatric and metabolic surgeries are associated with an increased risk for alcohol use disorder (AUD). Pediatricians treating children pre- or post-op should ensure that patients receive behavioral and mental health services to minimize the risk for alcohol abuse.

The risk for AUD is likely the result of changes to the way the body metabolizes alcohol, resulting in heightened sensitivity to it, although research is not conclusive, according to Dr. Mangarelli.

The risk for AUD is likely multifactorial, Dr. Mangarelli said.

“We don’t totally understand all of it, but if you’re experiencing a high more easily, that may lead to misuse,” Dr. Mangarelli said. “It’s also important to remember that this population of patients has experienced stigma for a very long time, and they often have associated mental health and body image issues.”

“Those problems don’t disappear on their own,” she added. “You want to make sure that patients are hooked into behavioral and mental health services before surgery so that they have somebody who’s following them after surgery.”
