The product received CE Mark in Europe in 2018 and is now available in 19 markets worldwide. It offers users a choice of bolusing directly from the pump or from a handheld remote-control device. The pump can be detached and reattached without wasting insulin.

The remote-control device also incorporates blood glucose monitoring and bolus advice, although it currently does not integrate with continuous glucose monitoring (CGM) devices.

A Roche spokesperson said in an interview, “For future product generations, we are exploring possibilities to integrate CGM data into the system. Already today, the diabetes manager allows users to manually enter a glucose value that can be used to calculate a bolus. To do so, people with diabetes could use their CGM device of choice in conjunction with the Accu-Chek Solo micropump system.”

Roche will provide an update on next steps for further developments and time lines for launch “in due course,” according to a company statement.

Significant reductions in hemoglobin A1c have occurred over time among adults with type 1 diabetes as their use of diabetes technology has increased, yet there is still room for improvement, new data suggest.

The new findings are from a study involving patients at the Barbara Davis Center for Diabetes Adult Clinic between Jan. 1, 2014, and Dec. 31, 2021. They show that as technology use has increased, A1c levels have dropped in parallel. Moreover, progression from use of stand-alone continuous glucose monitors (CGMs) to automated insulin delivery systems (AIDs), which comprise insulin pumps and connected CGMs, furthered that progress.

The findings “are in agreement with American Diabetes Association standards of care, and recent international consensus recommending CGM and AID for most people with type 1 diabetes, and early initiation of diabetes technology from the onset of type 1 diabetes,” write Kagan E. Karakus, MD, of the University of Colorado’s Barbara Davis Center, Aurora, and colleagues in the article, which was published online in Diabetes Care.

“It’s very rewarding to us. We can see clearly that the uptake is going up and the A1c is dropping,” lead author Viral N. Shah, MD, of the Barbara Davis Center, told this news organization.

On the flip side, A1c levels rose significantly over the study period among nonusers of technology. “We cannot rule out provider bias for not prescribing diabetes technology among those with higher A1c or from disadvantaged socioeconomic backgrounds,” Dr. Karakus and colleagues write.

Also of note, even with use of the most advanced AID systems available during the study period, just under half of patients were still not achieving A1c levels below 7%. “The technology helps, but it’s not perfect,” Dr. Shah observed.

This study is the first to examine the relationship of A1c with technology use over time, in contrast to prior cross-sectional studies. “The intention here was to look at the landscape over a decade,” Dr. Shah said.
 

As overall use of technology use rose, A1c levels fell

The analysis included data for 4,174 unique patients (mean number of patients, 1,988/yr); 15,903 clinic visits were included over the 8-year study period. Technology use was defined as CGM use without an AID system or with an AID system.

Over the study period, diabetes technology use increased from 26.9% to 82.7% of the clinic population (P < .001). At the same time, the overall proportion patients who achieved the A1c goal of less than 7% increased from 32.3% to 41.7%, while the mean A1c level dropped from 7.7% to 7.5% (P < .001).

But among the technology nonusers, A1c rose from 7.85% in 2014 to 8.4% in 2021 (P < .001).

Regardless of diabetes technology use, White patients (about 80% of the total study population) had significantly lower A1c than non-White patients (7.5% vs. 7.7% for technology users [P = .02]; 8.0% vs. 8.3% for nontechnology users [P < .001]).

The non-White group was too small to enable the researchers to break down the data by technology type. Nonetheless, Dr. Shah said, “As a clinician, I can say that the penetration of diabetes technology in non-White populations remains low. These are also the people more vulnerable for socioeconomic and psychosocial reasons.”

The A1c increase among technology nonusers may be a result of a statistical artifact, as the number of those individuals was much lower in 2021 than in 2014. It’s possible that those remaining individuals have exceedingly high A1c levels, bringing the average up. “It’s still not good, though,” Dr. Shah said.
 

The more technology, the lower the A1c

Over the study period, the proportion of stand-alone CGM users rose from 26.9% to 44.1%, while use of AIDs rose from 0% in 2014 and 2015 to 38.6% in 2021. The latter group included patients who used first-generation Medtronic 670G and 770G devices and second-generation Tandem t:slim X2 with Control-IQ devices.

Between 2017 and 2021, AIDs users had significantly lower A1c levels than nontechnology users: 7.4% vs. 8.1% in 2017, and 7.3% vs. 8.4% in 2021 (P < .001 for every year). CGM users also had significantly lower A1c levels than nonusers at all time points (P < .001 per year).

The proportions achieving an A1c less than 7% differed significantly across users of CGMs, AIDs, and no technology (P < .01 for all years). In 2021, the percentage of people who achieved an A1c less than 7% were 50.9% with AIDs and 44.1% for CGMs vs, just 15.2% with no technology.
 

Work to be done: Why aren’t more achieving < 7% with AIDs?

Asked why only slightly more than half of patients who used AIDs achieved A1c levels below 7%, Dr. Shah listed three possibilities:

First, the 7% goal doesn’t apply to everyone with type 1 diabetes, including those with multiple comorbidities or with short life expectancy, for whom the recommended goal is 7.5%-8.0% to prevent hypoglycemia. “We didn’t separate out patients by A1c goals. If we add that, the number might go up,” Dr. Shah said.

Second, AID technology is continually improving, but it’s not perfect. Users still must enter carbohydrate counts and signal the devices for exercise, which can lead to errors. “It’s a wonderful technology for overnight control, but still, during the daytime, there are so many factors with the user interface and how much a person is engaged with the technology,” Dr. Shah explained.

Third, he said, “Unfortunately, obesity is increasing in type 1 diabetes, and insulin doses are increasing. Higher BMI [body mass index] and more insulin resistance can mean higher A1c. I really think for many patients, we probably will need an adjunct therapy, such as an SGLT2 [sodium-glucose cotransporter-2] inhibitor or a GLP-1 [glucagonlike peptide-1] agonist, even though they’re not approved in type 1 diabetes, for both glycemic and metabolic control including weight. I think that’s another missing piece.”

He also pointed out, “If someone has an A1c of 7.5%, I don’t expect a huge change. But if they’re at 10%, a drop to 8% is a huge change.”

Overall, Dr. Shah said, the news from the study is good. “In the past, only 30% were achieving an A1c less than 7%. Now we’re 20% above that. ... It’s a glass half full.”

Dr. Karakus has disclosed no relevant financial relationships. Dr. Shah has received, through the University of Colorado, research support from Novo Nordisk, Insulet, Tandem Diabetes, and Dexcom, and honoraria from Medscape, Lifescan, Novo Nordisk, and DKSH Singapore for advisory board attendance and from Insulet and Dexcom for speaking engagements.

The Food and Drug Administration has approved palovarotene (Sohonos), the first-ever treatment for people with the rare and severely disabling bone condition fibrodysplasia ossificans progressiva (FOP).

Affecting roughly 400 people in the United States and 900 worldwide, FOP is an autosomal dominant condition in which bone develops in soft connective tissue areas of the body where it isn’t normally present (heterotopic ossification), such as the ligaments, tendons, and skeletal muscles. This leads to severe restriction in mobility and function, to the point that people lose the ability to feed or care for themselves. Most are completely disabled by age 30 years and median life expectancy is 56 years, with death often caused by bone formation around the rib cage restricting respiration.

“As a clinician caring for patients with FOP, I personally see the daily challenges and stresses that our patients and their families must contend with ... since the accumulation of heterotopic ossification in FOP is progressive, irreversible, and life altering. This medication is an important treatment option for our FOP community,” said endocrinologist Edward Hsiao, MD, professor of medicine at the University of California, San Francisco, in a statement from Ipsen.

Taken orally, palovarotene selectively targets the gamma subtype of retinoic acid receptors that regulate skeletal development and ectopic bone in the retinoid signaling pathway. The drug mediates interactions between these receptors, growth factors, and proteins within that pathway to reduce new abnormal bone formation.

It is now FDA approved for the treatment of FOP in female patients aged 8 years or older and male patients aged 10 years or older. The recommended dosing is 5 mg daily or weight-based equivalent for pediatric patients under 14 years of age, which can be modified or increased for flare-up symptoms. It is contraindicated during pregnancy.

The FDA approval was based on 18-month data from the phase 3, multicenter, open-label MOVE trial that included 107 adult and pediatric patients, over 10% of the world’s population with FOP. All received oral palovarotene and were compared with untreated individuals from a prior natural history study of the condition. The drug reduced annualized heterotopic ossification volume by 54%.

Side effects were typical of those seen with other systemic retinoid drugs, including mucocutaneous events such as dryness of the skin and mucous membranes, alopecia, drug eruption, rash, and pruritus, and musculoskeletal events, such as arthralgia and premature growth plate closure in growing children.

According to Dr. Hsiao, who was a MOVE investigator, the study “showed that Sohonos can decrease new heterotopic ossification, and that palovarotene can be tolerated by many patients with FOP. Sohonos is not for everyone. As with all medicines there are risks in this case especially for young children who may develop early growth plate closure. In addition, Sohonos has the same side effects as other retinoids.”

The FDA approval of palovarotene follows its rejection for marketing authorization in the European Union in July 2023.

Reached for comment, an Ipsen spokesperson said in an interview: “We reached the end of the regulatory process in the European Union for Sohonos and are disappointed the European Commission decided not to approved palovarotene for people with FOP in Europe.”

The company is developing another drug, fidrisertib, for treating FOP. A pivotal phase 2 trial for that drug is now recruiting patients. Asked where Ipsen might try to market fidrisertib, the spokesperson replied:“At this point, our focus is on the completion of the pivotal trial.”

Meanwhile, in the United States, the FOP community is celebrating the palovarotene approval. In a statement, Michelle Davis, executive director of the International Fibrodysplasia Ossificans Progressiva Association, said: “FOP is life altering to the individuals diagnosed and their families. There’s not a day that goes by where those impacted don’t worry about the debilitating physical pain of muscle that is replaced by bone, another joint locking, or the relentless emotional toll of losing the ability to do an activity they love, or hold a loved one close. ... The first treatment for FOP has been proven to reduce the volume of new abnormal bone growth, which may result in better health outcomes for people living with FOP.”

Ipsen is offering a patient support program to assist with education, coverage, and reimbursement (1-866-435-5677).

The Food and Drug Administration has approved palovarotene (Sohonos), the first-ever treatment for people with the rare and severely disabling bone condition fibrodysplasia ossificans progressiva (FOP).

Affecting roughly 400 people in the United States and 900 worldwide, FOP is an autosomal dominant condition in which bone develops in soft connective tissue areas of the body where it isn’t normally present (heterotopic ossification), such as the ligaments, tendons, and skeletal muscles. This leads to severe restriction in mobility and function, to the point that people lose the ability to feed or care for themselves. Most are completely disabled by age 30 years and median life expectancy is 56 years, with death often caused by bone formation around the rib cage restricting respiration.

“As a clinician caring for patients with FOP, I personally see the daily challenges and stresses that our patients and their families must contend with ... since the accumulation of heterotopic ossification in FOP is progressive, irreversible, and life altering. This medication is an important treatment option for our FOP community,” said endocrinologist Edward Hsiao, MD, professor of medicine at the University of California, San Francisco, in a statement from Ipsen.

Taken orally, palovarotene selectively targets the gamma subtype of retinoic acid receptors that regulate skeletal development and ectopic bone in the retinoid signaling pathway. The drug mediates interactions between these receptors, growth factors, and proteins within that pathway to reduce new abnormal bone formation.

It is now FDA approved for the treatment of FOP in female patients aged 8 years or older and male patients aged 10 years or older. The recommended dosing is 5 mg daily or weight-based equivalent for pediatric patients under 14 years of age, which can be modified or increased for flare-up symptoms. It is contraindicated during pregnancy.

The FDA approval was based on 18-month data from the phase 3, multicenter, open-label MOVE trial that included 107 adult and pediatric patients, over 10% of the world’s population with FOP. All received oral palovarotene and were compared with untreated individuals from a prior natural history study of the condition. The drug reduced annualized heterotopic ossification volume by 54%.

Side effects were typical of those seen with other systemic retinoid drugs, including mucocutaneous events such as dryness of the skin and mucous membranes, alopecia, drug eruption, rash, and pruritus, and musculoskeletal events, such as arthralgia and premature growth plate closure in growing children.

According to Dr. Hsiao, who was a MOVE investigator, the study “showed that Sohonos can decrease new heterotopic ossification, and that palovarotene can be tolerated by many patients with FOP. Sohonos is not for everyone. As with all medicines there are risks in this case especially for young children who may develop early growth plate closure. In addition, Sohonos has the same side effects as other retinoids.”

The FDA approval of palovarotene follows its rejection for marketing authorization in the European Union in July 2023.

Reached for comment, an Ipsen spokesperson said in an interview: “We reached the end of the regulatory process in the European Union for Sohonos and are disappointed the European Commission decided not to approved palovarotene for people with FOP in Europe.”

The company is developing another drug, fidrisertib, for treating FOP. A pivotal phase 2 trial for that drug is now recruiting patients. Asked where Ipsen might try to market fidrisertib, the spokesperson replied:“At this point, our focus is on the completion of the pivotal trial.”

Meanwhile, in the United States, the FOP community is celebrating the palovarotene approval. In a statement, Michelle Davis, executive director of the International Fibrodysplasia Ossificans Progressiva Association, said: “FOP is life altering to the individuals diagnosed and their families. There’s not a day that goes by where those impacted don’t worry about the debilitating physical pain of muscle that is replaced by bone, another joint locking, or the relentless emotional toll of losing the ability to do an activity they love, or hold a loved one close. ... The first treatment for FOP has been proven to reduce the volume of new abnormal bone growth, which may result in better health outcomes for people living with FOP.”

Exocrine pancreatic insufficiency (EPI) may be more common in both type 1 and type 2 diabetes than is currently appreciated, a new literature review suggests.

The condition – in which the pancreas fails to produce sufficient enzymes to fully digest food – can cause gastrointestinal symptoms, including steatorrhea or other stool changes, bloating, and/or abdominal pain. The preferred test for diagnosis is a 72-hour fecal fat quantification test, but fecal elastase-1 is a less invasive and reliable alternative; values of less than 200 mcg/g indicate EPI. Treatment is pancreatic enzyme replacement therapy (PERT), taken with every meal.

EPI occurs in up to 90% of people with cystic fibrosis and chronic pancreatitis and is commonly associated with acute pancreatitis, autoimmune pancreatitis, and pancreatic cancer. However, those conditions are relatively rare compared to diabetes, yet the EPI association with diabetes is less well-studied, Dana M. Lewis, BA, points out in her review article.

While the data vary across studies, owing to differences in inclusion and exclusion criteria, the overall median prevalence of EPI was 33% among patients with type 1 diabetes (range, 14%-77.5%) and 29% among patients with type 2 diabetes (range, 16.8%-49.2%), Ms. Lewis reports in the article, which was published in Diabetes Technology and Therapeutics.

“Cumulatively, this suggests there may be significant numbers of people with diabetes with EPI who are undiagnosed. People with diabetes who present with gastrointestinal symptoms – such as steatorrhea or changes in stool, bloating, and/or abdominal pain – should be screened for EPI. Diabetes specialists, gastroenterologists, and primary care providers should be aware of the high rates of prevalence of diabetes and EPI and recommend fecal elastase-1 screening for people with diabetes and GI symptoms,” Ms. Lewis writes.

Since the publication of her article, Ms. Lewis told this news organization, “I’ve gotten feedback from multiple diabetes and general providers that they will be changing their practice as a result of this paper, by screening people with diabetes who have GI symptoms for EPI, which is wonderful to hear.”

In addition, she noted that since she began blogging about EPI and diabetes last year following her own delayed diagnosis, “I have had at least half a dozen people with diabetes tell me that they’ve since sought screening for EPI after years of GI symptoms and ended up being diagnosed with EPI as well.”

Asked to comment, Romesh Khardori, MD, PhD, said in an interview, “it would be prudent to investigate EPI and treat it when confirmed. Consultation with a gastroenterologist colleague may be helpful. Treatment is quite rewarding.”
 

Data limitations; and don’t forget celiac disease and gastroparesis

However, as does Ms. Lewis, Dr. Khardori points to the limitations of the current literature.

“This review suffers from the lack of uniformity amongst the studies in terms of diagnosis and documentation of exocrine pancreatic insufficiency. Many studies lack a control group to draw any meaningful conclusions. Correlations with duration of diabetes, age of onset, symptoms, and glycemic control were mostly lacking,” says Dr. Khardori, now retired but formerly professor of medicine: endocrinology and metabolism at Eastern Virginia Medical School, Norfolk.

In general, the data suggest that PERT is safe and effective for people with diabetes and that it may reduce glycemic variability. However, “there are not many studies looking at glucose outcomes in detail, and only one study that has used CGM [continuous glucose monitoring] data, so this is a big area of need for future study,” Ms. Lewis told this news organization.

Ms. Lewis also reviewed the literature on the prevalence of two other diabetes-related gastrointestinal conditions, celiac disease and gastroparesis, “because anecdotally, it seems as though diabetes care providers and people with diabetes are more aware of those as causes of GI symptoms.”

In type 1 diabetes, the prevalence of both celiac disease and gastroparesis are reported at about 5%, in contrast to the 33% for EPI. Similarly, in type 2 diabetes, the reported prevalence of these two conditions are 1.3% and 1.6%, respectively, vs. 29% for EPI.

“This suggests to me that there is likely disproportionate screening for things like celiac [disease] and gastroparesis in diabetes, and that screening for EPI when people with diabetes present with GI symptoms is warranted,” Ms. Lewis said.

However, Dr. Khardori cautioned that those conditions may also be missed, noting, “Celiac disease often is undiagnosed and gastropathy or gastroparesis may be overlooked in a busy primary care clinic where most patients with diabetes mellitus get their care.”

Ms. Lewis and Dr. Khardori have disclosed no relevant financial relationships.

TOPLINE:

• No associations were found between preoperative A1c levels and postoperative infection, wound, or ketosis complications in children with type 1 or type 2 diabetes undergoing elective noncardiac surgery or diagnostic procedures.
• Delaying elective surgeries until A1c is consistently normalized may not be warranted, particularly because this is challenging to accomplish rapidly.

METHODOLOGY:

• A retrospective analysis was done of data from surgery and endocrinology medical records of 438 children aged 1-18 years with type 1 (72%) or type 2 diabetes (28%) undergoing elective noncardiac surgery at Texas Children’s Hospital, January 2011 to June 2021.
• Overall, 28% had an A1c less than 7.0%, 42% had A1c 7%-9%, and 30% had A1c greater than 9%.
• The primary outcome was defined as a new-onset postoperative systemic infection, wound complication, or ketosis.

TAKEAWAY:

• The incidence of any postoperative systemic infections was 0.91% (n = 4); postoperative wound disruption, 3.33% (n = 19); and postoperative ketosis, 3.89% (n = 17).
• A1c levels were not associated with any postoperative systemic infections, wound complications, or ketosis.
• No other preoperative factors, including diabetes type, body mass index, or procedure type, were association with these complications.

IN PRACTICE:

“Current recommendations suggest consulting with the diabetes team before surgery and if glycemic status is suboptimal to consider delaying surgery and, if surgery cannot be delayed, considering admission to the hospital before surgery for acute optimization of glycemia, However, there is no guidance on the level of elevated A1c that should prompt consideration of delaying surgery. This issue is of crucial importance because necessary elective surgery or diagnostic procedures may be delayed unnecessarily or for longer than needed in children with elevated A1c because of the difficulty of improving A1c levels rapidly.”

STUDY DETAILS:

The study was led by Grace Kim, MD, of the division of diabetes and endocrinology, Texas Children’s Hospital, Houston. It was published online August 1, 2023, in Diabetes Care.

LIMITATIONS:

• The postoperative complication rate was low.
• Only elective procedures were included.

The annual probability of a person with overweight or obesity losing at least 5% of their body weight is about 1 in 10, while weight loss to a healthy category is even less common, new research finds.

On the brighter side, those with higher body mass index (BMI) had greater odds of losing at least 5% of body weight than those with lower BMI, and women were more likely to do so than men. The chances of achieving a healthy weight category – defined as BMI of 18.5-24.9 kg/m² – was less likely than losing 5% in all groups, however.

Even a modest 5% weight loss at any BMI has been associated with improved health measures, including lower systolic and diastolic blood pressure, lower fasting glucose level, lower hemoglobin A1c level, and higher HDL cholesterol level, write Lyudmyla Kompaniyets, PhD, of the National Center for Chronic Disease Prevention and Health Promotion, Atlanta, and colleagues.

The data from more than 18 million U.S. adults from a nationwide ambulatory electronic medical record database, called IQVIA, suggest that “clinicians and public health efforts can focus on messaging and referrals to interventions that support individuals with excess weight in achieving and sustaining meaningful weight loss, i.e., ≥ 5% for adults at any level of excess weight,” the authors say.

The study population was health care–seeking but not necessarily for weight loss, and their intent to lose weight was unknown. “Several studies suggest that persons who are trying to lose weight may experience greater reductions in weight,” the researchers point out in their article, which was published in JAMA Network Open.

At the initial visit, 72.5% of the participants were categorized as having either overweight (BMI, 25.0-29.9kg/m²) or obesity (BMI, ≥ 30.0 kg/m²). The median age of the patients was 54 years. A little over half (56.7%) were women, 72.3% were White, and 7.7% were Black.

During a maximum follow-up period of 14 years, the proportion with 5% or greater weight loss was 33.4% of those with initial overweight and 41.8% with initial obesity. The proportion achieving healthy weight (BMI, 18.5-24.9 kg/m²) was just 23.2% and 2.0%, respectively.

For the combined overweight/obesity groups, the adjusted annual probability of 5% or greater weight loss was 1 in 10, increasing with BMI category from 1 in 12 for those with initial overweight to 1 in 6 for those with initial BMI of 45 kg/m² or higher. The annual probability was slightly lower among Black than White women (1 in 9 vs. 1 in 8, respectively).

In contrast, the adjusted annual probability of reducing BMI to the healthy category ranged from 1 in 19 with initial overweight to 1 in 1,667 with initial BMI of 45 kg/m² or higher. This probability was higher among women than men and was highest among White women.

“These findings could, in part, be explained by barriers in availability of and access to obesity management options, including lifestyle interventions and pharmacotherapy. There is a continual need for policies and strategies that ensure community access to nutrition and physical activity opportunities,” Dr. Kompaniyets and colleague write.

Moreover, they say, “understanding patterns of weight loss could help support populations, including Hispanic or Latino and non-Hispanic Black individuals, who are disproportionately affected by obesity due to factors such as structural racism and race and ethnicity-based social and economic disadvantages.”

The authors have disclosed no relevant financial relationships.

During a maximum follow-up period of 14 years, the proportion with 5% or greater weight loss was 33.4% of those with initial overweight and 41.8% with initial obesity. The proportion achieving healthy weight (BMI, 18.5-24.9 kg/m²) was just 23.2% and 2.0%, respectively.

For the combined overweight/obesity groups, the adjusted annual probability of 5% or greater weight loss was 1 in 10, increasing with BMI category from 1 in 12 for those with initial overweight to 1 in 6 for those with initial BMI of 45 kg/m² or higher. The annual probability was slightly lower among Black than White women (1 in 9 vs. 1 in 8, respectively).

In contrast, the adjusted annual probability of reducing BMI to the healthy category ranged from 1 in 19 with initial overweight to 1 in 1,667 with initial BMI of 45 kg/m² or higher. This probability was higher among women than men and was highest among White women.

“These findings could, in part, be explained by barriers in availability of and access to obesity management options, including lifestyle interventions and pharmacotherapy. There is a continual need for policies and strategies that ensure community access to nutrition and physical activity opportunities,” Dr. Kompaniyets and colleague write.

Moreover, they say, “understanding patterns of weight loss could help support populations, including Hispanic or Latino and non-Hispanic Black individuals, who are disproportionately affected by obesity due to factors such as structural racism and race and ethnicity-based social and economic disadvantages.”

Skin reactions at insulin pump infusion sites are common among people with type 1 diabetes who use the devices and can lead to delivery failure, new research suggests.
 

Insulin pump use is increasingly common, but many patients experience infusion-site failure that in some cases leads to discontinuation. In a novel investigation, researchers at the University of Washington, Seattle, used biopsies and noninvasive imaging to compare insulin pump sites with control sites in 30 patients. Several differences were found at pump sites in comparison with control sites, including fibrosis, inflammation, eosinophils, and increased vessel density.

“These findings support allergic sensitization as a potentially common reaction at [insulin pump] sites. The leading candidates causing this include insulin preservatives, plastic materials, and adhesive glue used in device manufacturing,” wrote Andrea Kalus, MD, of the university’s dermatology division, and colleagues. The findings were published recently in Diabetes Care.

The inflammatory response, they wrote, “may result in tissue changes responsible for the infusion-site failures seen frequently in clinical practice.”

Such infusion site problems represent an “Achilles heel” of these otherwise highly beneficial devices, lead author Irl Hirsch, MD, professor of medicine in the division of metabolism, endocrinology, and nutrition, said in a statement. “It doesn’t really matter how good the technology is. We still don’t understand what is happening with the infusion sites, much less to [be able to] fix it.”
 

Significant differences between pump and nonpump sites

In the cross-sectional study, Dr. Kalus and colleagues used noninvasive optical coherence tomography (OCT) immediately prior to performing punch biopsies at three sites: the site currently in active use, the “recovery site” used 3-5 days prior to the procedures, and control sites never used for pump infusion. Punch biopsies were also performed at those sites.

The mean age of the patients was 48.3 years, the mean diabetes duration was 30.4 years, and the mean duration of pump use was 15.8 years. Nearly all patients (93.3%) reported itchiness at the site, and 76.7% reported skin redness.

Of the 25 patients for whom OCT imaging was successful, statistical analysis showed significant differences in vascular area density and the optical attenuation coefficient, a surrogate for skin inflammation, between the pump and control sites and between recovery sites and current pump sites. The greater vessel density is likely a result of injury and repair related to catheter insertion, the authors said.

In the biopsy samples, both current and recovery sites showed increased fibrosis, fibrin, inflammation, fat necrosis, vascularity, and eosinophils, compared with the control sites, but no significant differences were found between current and recovery sites.

Eosinophils: ‘The most surprising histologic finding’

Eosinophils were found in 73% of skin biopsy specimens from current sites and in 75% of specimens from recovery sites, compared with none from the control sites (for both, P < .01). In all study participants, eosinophils were found in at least one current and/or recovery infusion site deep in the dermis near the interface with fat. The number of eosinophils ranged from 0 to 31 per high-power field, with a median of 4.

The number of eosinophils didn’t vary by type of insulin or brand of pump, but higher counts were seen in those who had used pumps for less than 10 years, compared with more than 20 years (P = .02).

The prevalence and degree of eosinophils were “the most surprising histologic finding,” the authors wrote, adding that “eosinophils are not typically present as a component of resident inflammatory cells in the skin.”

While eosinophils may be present in normal wound healing, “the absolute number and density of eosinophil in these samples support a delayed-type hypersensitivity response, which is typically observed between 2 and 7 days after exposure to an allergen. ... Eosinophils are often correlated with symptoms of itchiness and likely explain the high percentage of participants who reported itchiness in this study,” Dr. Kalus and colleagues wrote.
 

Correlation found between inflammation and glycemic control

All participants used the Dexcom G6 continuous glucose monitor as part of their usual care. Inflammation scores were positively correlated with insulin dose (P = .009) and were negatively correlated with time in range (P = .01).

No other OCT or biopsy findings differed by duration of pump use, previous use of animal insulin, or type of insulin.

The reason for these findings is unclear, Dr. Hirsch said. “How much was the catheter or the insulin causing the irritation around the sites? How much was it from the preservatives, or is this because of the insulin pump itself? All these questions need to be answered in future studies. ... The real goal of all of this is to minimize skin damage and improve the experience for our patients.”

The study was funded by the Leona M. and Harry B. Helmsley Charitable Trust. Dr. Hirsch reported grants and contracts from Insulet, Medtronic, and Dexcom outside the submitted work; consulting fees from Abbott Diabetes Care, Lifescan, and Hagar outside the submitted work; and honoraria for lectures, presentations, participation on speaker’s bureaus, manuscript writing, or educational events as section editor for UpToDate outside the submitted work. Dr. Kalus has no disclosures.

TOPLINE:

A pilot study suggests that kombucha consumption reduces blood glucose levels in adults with type 2 diabetes. The sample size was too small for statistical significance.

METHODOLOGY:

• Prospective, randomized, double-blinded, crossover study at a single-center urban hospital system.
• A total of 12 participants with type 2 diabetes were randomly assigned to consume 240 mL of either a kombucha product or placebo daily with dinner for 4 weeks.
• After an 8-week washout, they were switched to the other product for another 4 weeks.
• Fasting blood glucose levels were self-determined at baseline and at 1 and 4 weeks, and questionnaires were used to assess secondary health outcomes.
• Questionnaire data were analyzed for all 12 participants, but only 7 who completed the study were included in the analysis of fasting blood glucose.

TAKEAWAY:

• Kombucha significantly lowered average fasting blood glucose levels at week 4, compared with baseline (164 vs. 116 mg/dL; P = .035), while the placebo was not associated with statistically significant change (162 vs. 141 mg/dL; P = .078).
• Among just the five participants with baseline fasting glucose > 130 mg/dL, kombucha consumption was associated with a mean fasting blood glucose decrease of 74.3 mg/dL, significantly greater than the 15.9 mg/dL drop with placebo (P = .017).
• On cultural enumeration, the kombucha contained mostly lactic acid bacteria, acetic acid bacteria, and yeast, with molds present.

IN PRACTICE:

“Kombucha is a growing part of the beverage market in the United States and the world, driven, in part, by the wide range of suggested health benefits. However, nearly all of these benefits are based on in vitro or animal studies, and human clinical trials are needed to validate biological outcomes.”

SOURCE:

The study was conducted by Chagai Mendelson, of MedStar Georgetown University Hospital, Washington, and colleagues. It was published in Frontiers in Nutrition.

LIMITATIONS:

• The number of participants was small, and attrition was high.
• Glucose levels were self-reported.
• Only one kombucha was studied.

DISCLOSURES:

One author is a cofounder of Synbiotic Health and another has a financial interest in the company. The other authors have no disclosures. Kombucha and placebo drinks were donated by Craft Kombucha, but the company did not have access to the data, and no authors have financial ties with that company.

A new discovery of differences between the eyes of people with and without diabetes could point to new approaches for treating diabetic keratopathy, as well as other diabetes-related wound healing problems.

Vision loss caused by diabetes arises primarily from retinopathy, but up to 70% of people with diabetes also experience corneal problems, including keratopathy and neuropathy. Diabetic keratopathy involves impairments in epithelial wound healing, barrier function, and tear production, along with epithelial erosions and keratitis. As a result, the cornea may heal more slowly and less completely following an injury or procedures such as cataract surgery or laser therapy for diabetic retinopathy.

The abnormal wound healing is caused by impaired limbal epithelial stem cells, and the new research, published online in Diabetologia, involved isolation of those cells from 30 donor eyes of humans with and 23 without diabetes. Significant differences were found in DNA methylation between the cells of those two groups. Specifically, the WNT5A gene was hypermethylated at the promotor region in the diabetic cells and its protein markedly repressed.

However, treatment with various approaches, including exogenous WNT5A methylation inhibitors and a nanoconjugate that inhibits WNT5A suppression, improved corneal epithelial wound healing as well as expression of the limbic epithelial stem cells.

“Overall, [the] Wnt-5a [protein] is a new corneal epithelial wound healing stimulator that can be targeted to improve wound healing and stem cells in the diabetic cornea,” wrote Ruchi Shah, PhD, of the Board of Governors Regenerative Medicine Institute, Cedars-Sinai Medical Center, Los Angeles, and colleagues.

The finding represents more cellular changes than researchers had previously been aware of, study senior author Alexander Ljubimov, PhD, DSc, director of the eye program at the Institute, said in a statement.

“The discovery does not affect gene sequence but entails specific DNA modifications altering gene expression – what are known as epigenetic alterations,” he said.

In the experiments, treatment of the impaired diabetic limbal epithelial cells with the exogenous Wnt-5a accelerated wound healing by 1.4-fold (P < .05), compared with untreated cells and reduced healing time in diabetic organ-ultured corneas by 37% (P < .05).

Treatment with the DNA methylation inhibitor zebularine also increased levels of Wnt-5a in the diabetic limbic epithelial cells by 37% (P < .01), dose-dependently stimulated wound healing by 60% at 24 hours (P < .01), and improved wound healing by 30% in diabetic organ-cultured corneas.

The finding of Wnt-5a as a new diabetic corneal marker regulating wound healing and stem cell function may have implications for other diabetes complications involving impaired wound healing, including diabetic foot ulcers, as they share similar neurovascular, sensory, and immunological compromise with diabetic eye disease, Dr. Shah and colleagues wrote.

“Novel therapies to reverse both types of epigenetic silencing could benefit corneal function and may also prove to be beneficial in other wound healing–related diabetic complications,” they wrote.

The investigators are now working on combination therapies that target both mRNA and DNA methylation in hopes of obtaining even better wound healing.

“Our goal is to develop topical, sustained-release drugs for corneal wound healing,” said Dr. Ljubimov. “Drugs that are [Food and Drug Administration] approved and could be easily applied may be one of the most promising approaches for effective future therapies.”

This work was funded by the National Institutes of Health and the Cedars-Sinai Board of Governors Regenerative Medicine Institute. The authors reported no further disclosures.

Treatment with the DNA methylation inhibitor zebularine also increased levels of Wnt-5a in the diabetic limbic epithelial cells by 37% (P < .01), dose-dependently stimulated wound healing by 60% at 24 hours (P < .01), and improved wound healing by 30% in diabetic organ-cultured corneas.

The finding of Wnt-5a as a new diabetic corneal marker regulating wound healing and stem cell function may have implications for other diabetes complications involving impaired wound healing, including diabetic foot ulcers, as they share similar neurovascular, sensory, and immunological compromise with diabetic eye disease, Dr. Shah and colleagues wrote.

“Novel therapies to reverse both types of epigenetic silencing could benefit corneal function and may also prove to be beneficial in other wound healing–related diabetic complications,” they wrote.

The investigators are now working on combination therapies that target both mRNA and DNA methylation in hopes of obtaining even better wound healing.

“Our goal is to develop topical, sustained-release drugs for corneal wound healing,” said Dr. Ljubimov. “Drugs that are [Food and Drug Administration] approved and could be easily applied may be one of the most promising approaches for effective future therapies.”

New guidelines from the American Association of Clinical Chemistry (AACC) and American Diabetes Association (ADA) address laboratory measures in the diagnosis and management of diabetes.

The document, titled, “Guidelines and recommendations for laboratory analysis in the diagnosis and management of diabetes mellitus,” is primarily aimed at both laboratory professionals and clinicians involved in diabetes care.

The guidance is focused “on the practical aspects of care in order to assist with decisions regarding the use or interpretation of laboratory tests while screening, diagnosing, or monitoring patients with diabetes,” wrote David B. Sacks, MBChB, chief of the clinical chemistry service at the National Institutes of Health (NIH), Bethesda, Md., and coauthors. It was published online in both Clinical Chemistry and Diabetes Care, including the guidelines and executive summary.  

Coauthor M. Sue Kirkman, MD, of the University of North Carolina, Chapel Hill, said in an interview: “One objective of the guidelines is to increase clinicians’ understanding of the strengths and limitations of tests done in a laboratory and also at the point of care, or in daily life, by people with diabetes.”

The evidence-based recommendations, an update of prior versions published in 2011 and 2002, are meant as a supplement to the ADA Standards of Care in Diabetes and do not address aspects of clinical management, she stressed.
 

Addition of advice on CGM

A significant addition since 2011 is detailed information regarding the use of real-time continuous glucose monitoring (CGM), with a “strong” recommendation based on a “high” level of evidence for use in teens and adults with type 1 diabetes who meet certain criteria, and lower-grade advice to use real-time or intermittently scanned CGM in other populations, including children with diabetes, pregnant women with type 1 diabetes, and adults with type 2 diabetes taking insulin.

The document also reminds clinicians to consider test limitations, Dr. Kirkman pointed out.

“We do a lot of testing in screening, diagnosis, and monitoring of diabetes and its complications, yet for many clinicians we think that any result we get – or that a patient gets from home testing – is perfect. We often don’t think about the accuracy or precision of some tests, things that might interfere with the result, intra-individual variation of the test, or how one test may compare to a test of higher accuracy,” she said.

One example is a recommendation to collect blood samples for glucose analysis in tubes containing a rapidly effective inhibitor of glycolysis such as a granulated citrate buffer. If unavailable, the sample tube should be placed immediately into an ice water slurry and centrifuged within 15-30 minutes to remove the cells.

Without those measures, “red cells in blood sitting in the test tube continue to break down glucose, so the concentration of glucose will start to fall very soon. ... How the specimen is handled makes a huge difference in the result,” Dr. Kirkman emphasized.

Another is the recommendation of a confirmatory test when diagnosing diabetes, regardless of the initial test used (A1c, fasting glucose, or oral glucose tolerance test). “There is large intra-individual variation of fasting glucose and even larger for 2-hour glucose on the oral glucose tolerance test. ... This means if you do the test one week and then repeat it the next day or a week later, the results will be quite different. This is a reason why confirmation of an abnormal test is important. Yet many times this isn’t done,” she noted.

Other “strong” recommendations based on “high” evidence levels include:

• Fasting glucose should be measured in venous plasma when used to establish the diagnosis of diabetes, with a diagnostic cutoff of > 7.0 mmol/L (> 126 mg/dL) for diabetes.
• Frequent blood glucose monitoring is recommended for all people with diabetes treated with intensive insulin regimens (with multiple daily injections or insulin pump therapy) and who are not using CGM.
• Routine use of blood glucose monitoring is not recommended for people with type 2 diabetes who are treated with diet and/or oral agents alone.
• Treatment goals should be based on ADA recommendations, i.e., A1c < 7% (< 53 mmol/mol) if it can be achieved without significant hypoglycemia or other adverse treatment effects, with higher targets for special populations.
• Annual testing for albuminuria should begin in pubertal or postpubertal individuals 5 years after diagnosis of type 1 diabetes and at time of diagnosis of type 2 diabetes, regardless of treatment.
• Urine albumin should be measured annually in adults with diabetes using morning spot urine albumin-to-creatinine ratio.

Other guidance in the document pertains to use of ketone testing, genetic markers, autoimmune markers, and C-peptide.

According to Dr. Sacks, “It’s important to measure accurately, but it’s also very important to communicate the relevance to clinicians and to listen to them and share information. ... Patient care is a team effort.”

Dr. Sachs has reported receiving funding from the NIH. Dr. Kirkman has reported no relevant financial relationships.
