Intermittent fasting good for weight loss, at least short term
The health benefits of intermittent fasting are slowly being clarified as more evidence continues to emerge, say the authors of a new review of 21 studies. Initial findings suggest that fasting might be effective for mild to moderate weight loss for certain groups of people, at least in the short term.
And data so far at least dispel the myth that “people are going to feel weak and not be able to concentrate during fasting,” lead researcher Krista A. Varady, PhD, professor of nutrition in the University of Illinois at Chicago, noted in a press release from her university.
“We’ve shown it is the opposite,” she said. “They actually have a better ability to concentrate.”
Yet much longer-term data are needed on issues such as safety, Dr. Varady and colleagues note in their review in Nature Reviews: Endocrinology .
The trials so far have only been conducted in adults – generally with overweight or obesity and sometimes hypertension, dyslipidemia, and/or diabetes – but some have been performed in those of normal weight.
Dr. Varady and colleague recommend that those with type 1 diabetes, type 2 diabetes, or other comorbidities, or patients who need to take medications with meals at certain times of the day, should seek clinical supervision when considering intermittent fasting.
And currently, based on existing evidence, intermittent fasting is contraindicated for children under age 12 and those who have a history of an eating disorder or a body mass index <18.5 kg/m2. Opinions vary about the safety of supervised fasting in adolescents with obesity. Also, safety has not been evaluated in those older than age 70, and in women who are pregnant or lactating.
‘A few studies’ show 3%-8% weight loss over 2-3 months
Despite the recent surge in the popularity of intermittent fasting, “only a few studies have examined the health benefits of these diets in humans,” Dr. Varady and coauthors emphasize.
They identified 21 clinical trials of three types of intermittent fasting strategies:
Alternate day fasting (alternating between consuming 0-500 kcal on “fasting” days, followed by unlimited food on “feasting” days), six trials.
5:2 diet (“feasting” on 5 days and “fasting” on 2 days), seven trials.
Time-restricted eating (eating during a 4- to 8- hour window), nine trials.
The trials were short (mostly 5-12 weeks long) and small (10-150 participants), and mostly conducted in the United States.
They found these strategies can all produce a mild to moderate 3%-8% weight loss during 8-12 weeks, similar to that attained with a calorie-restricted diet.
Some studies found that patients had improvements in blood pressure, LDL cholesterol, triglycerides, insulin resistance, and hemoglobin A1c.
These weight-loss strategies produced few gastrointestinal, neurological, hormonal, or metabolic adverse effects; “however, as adverse outcomes are not regularly assessed in human trials of fasting, definitive conclusions regarding the safety of these diets are difficult to draw at present,” the researchers caution.
Practical advice, great anecdotes
Typically, 1-2 weeks of adjustment is needed when individuals start intermittent fasting, the researchers say.
While following this eating pattern, patients should be encouraged to consume plenty of fruits, vegetables, and whole grains to boost their fiber and micronutrient intake.
On fasting days, they should consume at least 50 g of lean protein to help control hunger and prevent excessive loss of lean mass. On those days, alcohol is permitted but not recommended. Energy drinks and coffee or tea without sugar, milk, or cream are allowed, and diet soda should be limited to two servings a day because it can increase sugar cravings.
Ideally, clinicians should regularly assess patients for adverse effects during the first 3 months of intermittent fasting. They should also monitor patients for deficiencies in vitamin D, vitamin B12, and electrolytes, as well as for changes in medications for blood pressure, lipids, and glucose that may be needed if patients lose weight.
Patients who reach their weight-loss goals and wish to stop intermittent fasting need to transition to a weight-maintenance program, possibly by increasing energy intake on fasting days to 1,000-1,200 kcal/day or widening the eating window to 12 hours in time-restricted eating.
“I get lots of emails from people saying that they have been on the diet for 10-15 years, and it reversed their type 2 diabetes, and they lost 60 pounds, and it was the only diet they could stick to,” Dr. Varady noted.
“That is always nice to hear, but we really do need long-term data to see if people can do intermittent fasting for the long term,” she reiterated.
The review was funded by the National Institute of Diabetes and Digestive and Kidney Diseases. Dr. Varady received author fees from the Hachette Book Group for the book, “The Every Other Day Diet.” The other authors have declared no relevant financial relationships.

FROM NATURE REVIEWS: ENDOCRINOLOGY
Mild COVID-19 infection linked to later type 2 diabetes
People who recover from a mild case of COVID-19 appear to have an increased risk for subsequent new-onset type 2 diabetes but not other types of diabetes, new data suggest.
“If confirmed, the results of the present study indicate that diabetes screening in individuals who have recovered from even mild COVID-19 should be recommended,” say Wolfgang Rathmann, MD, of the Leibniz Center for Diabetes Research at Heinrich Heine University, Düsseldorf, Germany, and colleagues.
The findings, from a nationwide primary care database in Germany, were recently published in Diabetologia.
These primary care data align with those from other studies of more seriously ill patients with COVID-19 that found increased rates of type 2 diabetes diagnoses in the subsequent months following illness, they point out.
“COVID-19 infection may lead to diabetes by upregulation of the immune system after remission, which may induce pancreatic beta-cell dysfunction and insulin resistance, or patients may have been at risk for developing diabetes due to having obesity or prediabetes, and the stress COVID-19 put on their bodies sped it up,” said Dr. Rathmann in a press release.
However, because the patients with COVID-19 in the study were only followed for about 3 months, “further follow-up is needed to understand whether type 2 diabetes after mild COVID-19 is just temporary and can be reversed after they have fully recovered or whether it leads to a chronic condition,” he noted.
Increase in type 2 diabetes 3 months after mild COVID-19
The retrospective cohort analysis was performed using data from the Disease Analyzer, a representative panel of 1,171 physician practices in Germany, from March 2020 to January 2021, with follow-up through July 2021.
Individuals with a history of COVID-19 or diabetes and those taking corticosteroids within 30 days after the index dates were excluded.
A total of 35,865 patients with confirmed SARS-CoV-2 infection were propensity score-matched on a one-to-one basis for sex, age, health insurance, and comorbidities with those who had acute respiratory tract infections (controls) but were COVID-19 negative. Median follow-up was 119 days for the COVID-19 group and 161 days for controls.
There was a 28% increased risk of type 2 diabetes for those who had COVID-19 versus controls (15.8 per 1,000 person-years vs. 12.3 per 1,000 person-years, respectively, which was significantly different, and an incidence rate ratio of 1.28).
The incidence of other types of diabetes or unspecified diabetes for the COVID-19 and control groups did not differ significantly (4.3 per 1,000 person-years vs. 3.7 per 1,000 person-years; IRR, 1.17).
Similar findings were seen in sensitivity analyses by glucose-lowering medication prescriptions and by ICD-10 codes.
Although type 2 diabetes is not likely to be a problem for the vast majority of people who have mild COVID-19, the authors recommend that anyone who has recovered from COVID-19 be aware of the warning signs and symptoms such as fatigue, frequent urination, and increased thirst, and seek treatment right away.
CoviDiab registry tracking type 1 and type 2 diabetes
Over the course of the pandemic, there have been conflicting data on whether COVID-19 induces or reveals a propensity for type 1 and type 2 diabetes.
The CoviDiab global registry is tracking this and will include diabetes type for adults and children.
The aim is to have “as many as possible cases of new-onset diabetes for which we can have also a minimum set of clinical data including type of diabetes and A1c,” coprincipal investigator Francesco Rubino, MD, of King’s College London, previously told this news organization.
“By looking at this information we can infer whether a role of COVID-19 in triggering diabetes is clinically plausible – or not – and what type of diabetes is most frequently associated with COVID-19.”
Rubino said that the CoviDiab team is approaching the data with the assumption that, at least in adults diagnosed with type 2 diabetes, the explanation might be that the person already had undiagnosed diabetes or the hyperglycemia may be stress-induced and temporary.
The German Diabetes Center is funded by the German Federal Ministry of Health and the Ministry of Culture and Science of the State of North Rhine-Westphalia. Dr. Rathmann has reported receiving consulting fees for attending educational sessions or advisory boards for AstraZeneca, Boehringer Ingelheim, and Novo Nordisk and institutional research grants from Novo Nordisk outside of the topic of the current work.

Empagliflozin scores topline win in EMPA-KIDNEY trial
Researchers running the EMPA-KIDNEY trial that’s been testing the safety and efficacy of the SGLT2 inhibitor empagliflozin (Jardiance) in about 6,600 patients with chronic kidney disease (CKD) announced on March 16 that they had stopped the trial early because of positive efficacy that met the study’s prespecified threshold for early termination.
EMPA-KIDNEY is the third major trial of an agent from the sodium-glucose cotransport 2 (SGLT2) inhibitor class tested in patients with CKD to be stopped early because of positive results that met a prespecified termination rule.
In 2020, the DAPA-CKD trial of dapagliflozin (Farxiga) stopped early, after a median follow-up of 2.4 years, because of positive efficacy results. In 2019, the same thing happened in the CREDENCE trial of canagliflozin (Invokana), with the unexpected halt coming after a median follow-up of 2.62 years.
The announcement about EMPA-KIDNEY did not include information on median follow-up, but enrollment into the trial ran from May 2019 to April 2021, which means that the longest that enrolled patients could have been in the study was about 2.85 years.
The primary efficacy endpoint in EMPA-KIDNEY was a composite of a sustained decline in estimated glomerular filtration rate (eGFR) to less than 10 mL/min/1.73 m2, renal death, a sustained decline of at least 40% in eGFR from baseline, or cardiovascular death. The announcement of the trial’s early termination provided no details on the efficacy results.
EMPA-KIDNEY enrolled a wider range of patients
EMPA-KIDNEY expands the scope of types of patients with CKD now shown to benefit from treatment with an SGLT2 inhibitor. CREDENCE tested canagliflozin only in patients with type 2 diabetes and diabetic nephropathy, and in DAPA-CKD, two-thirds of enrolled patients had type 2 diabetes, and all had CKD. In EMPA-KIDNEY, 46% of the 6,609 enrolled patients had diabetes (including a very small number with type 1 diabetes).
Another departure from prior studies of an SGLT2 inhibitor for patients selected primarily for having CKD was that in EMPA-KIDNEY, 20% of patients did not have albuminuria, and for 34%, eGFR at entry was less than 30 mL/min/1.73 m2, with all enrolled patients required to have an eGFR at entry of greater than or equal to 20 mL/min/1.73 m2. Average eGFR in EMPA-KIDNEY was about 38 mL/min/1.73 m2. To be included in the trial, patients were not required to have albuminuria, except those whose eGFR was greater than or equal to 45 mL/min/1.73 m2.
In DAPA-CKD, the minimum eGFR at entry had to be greater than or equal to 25 mL/min/1.73 m2, and roughly 14% of enrolled patients had an eGFR of less than 30 mL/min/1.73 m2. The average eGFR in DAPA-CKD was about 43 mL/min/1.73 m2. In addition, all patients had at least microalbuminuria, with a minimum urinary albumin-to-creatinine ratio of 200. In CREDENCE, the minimum eGFR for enrollment was 30 mL/min/1.73 m2, and the average eGFR was about 56 mL/min/1.73 m2. All patients in CREDENCE had to have macroalbuminuria, with a urinary albumin-to-creatinine ratio of more than 300.
According to the researchers who designed EMPA-KIDNEY, the trial enrollment criteria aimed to include adults with CKD “who are frequently seen in practice but were under-represented in previous SGLT2 inhibitor trials.”
Indications for empagliflozin are expanding
The success of empagliflozin in EMPA-KIDNEY follows its positive results in both the EMPEROR-Reduced and EMPEROR-Preserved trials, which collectively proved the efficacy of the agent for patients with heart failure regardless of their left ventricular ejection fraction and regardless of whether they also had diabetes.
These results led the U.S. Food and Drug Administration to recently expand the labeled indication for empagliflozin to all patients with heart failure. Empagliflozin also has labeled indications for glycemic control in patients with type 2 diabetes and to reduce the risk of cardiovascular death in adults with type 2 diabetes and established cardiovascular disease.
As of today, empagliflozin has no labeled indication for treating patients with CKD. Dapagliflozin received that indication in April 2021, and canagliflozin received an indication for treating patients with type 2 diabetes, diabetic nephropathy, and albuminuria in September 2019.
EMPA-KIDNEY is sponsored by Boehringer Ingelheim and Lilly, the two companies that jointly market empagliflozin (Jardiance).

The announcement of the trial’s early termination provided no details on the efficacy results.
EMPA-KIDNEY enrolled a wider range of patients
EMPA-KIDNEY expands the scope of types of patients with CKD now shown to benefit from treatment with an SGLT2 inhibitor. CREDENCE tested canagliflozin only in patients with type 2 diabetes and diabetic nephropathy, and in DAPA-CKD, two-thirds of enrolled patients had type 2 diabetes, and all had CKD. In EMPA-KIDNEY, 46% of the 6,609 enrolled patients had diabetes (including a very small number with type 1 diabetes).
Another departure from prior studies of an SGLT2 inhibitor for patients selected primarily for having CKD was that in EMPA-KIDNEY, 20% of patients did not have albuminuria, and for 34%, eGFR at entry was less than 30 mL/min/1.73 m2, with all enrolled patients required to have an eGFR at entry of greater than or equal to 20 mL/min/1.73 m2. Average eGFR in EMPA-KIDNEY was about 38 mL/min/1.73 m2. To be included in the trial, patients were not required to have albuminuria, except those whose eGFR was greater than or equal to 45 mL/min/1.73 m2.
In DAPA-CKD, the minimum eGFR at entry had to be greater than or equal to 25 mL/min/1.73 m2, and roughly 14% of enrolled patients had an eGFR of less than 30 mL/min/1.73 m2. The average eGFR in DAPA-CKD was about 43 mL/min/1.73 m2. In addition, all patients had at least microalbuminuria, with a minimum urinary albumin-to-creatinine ratio of 200. In CREDENCE, the minimum eGFR for enrollment was 30 mL/min/1.73 m2, and the average eGFR was about 56 mL/min/1.73 m2. All patients in CREDENCE had to have macroalbuminuria, with a urinary albumin-to-creatinine ratio of more than 300.
According to the researchers who designed EMPA-KIDNEY, the trial enrollment criteria aimed to include adults with CKD “who are frequently seen in practice but were under-represented in previous SGLT2 inhibitor trials.”
Indications for empagliflozin are expanding
The success of empagliflozin in EMPA-KIDNEY follows its positive results in both the EMPEROR-Reduced and EMPEROR-Preserved trials, which collectively proved the efficacy of the agent for patients with heart failure regardless of their left ventricular ejection fraction and regardless of whether they also had diabetes.
These results led the U.S. Food and Drug Administration to recently expand the labeled indication for empagliflozin to all patients with heart failure. Empagliflozin also has labeled indications for glycemic control in patients with type 2 diabetes and to reduce the risk of cardiovascular death in adults with type 2 diabetes and established cardiovascular disease.
As of today, empagliflozin has no labeled indication for treating patients with CKD. Dapagliflozin received that indication in April 2021, and canagliflozin received an indication for treating patients with type 2 diabetes, diabetic nephropathy, and albuminuria in September 2019.
EMPA-KIDNEY is sponsored by Boehringer Ingelheim and Lilly, the two companies that jointly market empagliflozin (Jardiance).

Researchers running the EMPA-KIDNEY trial that’s been testing the safety and efficacy of the SGLT2 inhibitor empagliflozin (Jardiance) in about 6,600 patients with chronic kidney disease (CKD) announced on March 16 that they had stopped the trial early because of positive efficacy that met the study’s prespecified threshold for early termination.
EMPA-KIDNEY is the third major trial of an agent from the sodium-glucose cotransport 2 (SGLT2) inhibitor class tested in patients with CKD to be stopped early because of positive results that met a prespecified termination rule.
In 2020, the DAPA-CKD trial of dapagliflozin (Farxiga) stopped early, after a median follow-up of 2.4 years, because of positive efficacy results. In 2019, the same thing happened in the CREDENCE trial of canagliflozin (Invokana), with the unexpected halt coming after a median follow-up of 2.62 years.
The announcement about EMPA-KIDNEY did not include information on median follow-up, but enrollment into the trial ran from May 2019 to April 2021, which means that the longest that enrolled patients could have been in the study was about 2.85 years.

Food insecurity linked to metabolic syndrome in Hispanic/Latino youth
Severe food insecurity was associated with metabolic syndrome and unfavorable cardiometabolic markers in Hispanic/Latino youth, researchers report.
The findings, published March 16 in Pediatrics, highlight the need to investigate interventions that address food insecurity among Hispanic/Latino youth, a segment of the U.S. population at high risk of cardiometabolic complications.
“Among Hispanic/Latino youth, no study, to our knowledge has evaluated food insecurity’s role in metabolic syndrome and metabolic syndrome–relevant cardiometabolic markers in this population,” lead author Luis E. Maldonado, PhD, of the University of North Carolina at Chapel Hill, and colleagues explained.
The researchers conducted a cross-sectional study to evaluate the associations between lower household and child food security and metabolic syndrome, as well as clinically measured cardiometabolic markers, including fasting plasma glucose, waist circumference, triglycerides, systolic and diastolic blood pressure, and high-density lipoprotein cholesterol (HDL-C).
Household food security (high, marginal, low, very low) and child food security (high, marginal, low/very low) measures were evaluated separately, and were adjusted for participant age, sex, site, parental education, and poverty-income ratio.
Data were obtained from the Hispanic Community Children’s Health Study/Study of Latino Youth, a study of offspring of adults enrolled in the Hispanic Community Health Survey/Study of Latinos.
Results
The study cohort included 1,325 Hispanic/Latino youth aged 8-16 years. For both household food security and child food security, youth in the lowest food security category had significantly lower HDL-C compared with youth with high food security (household food security, –3.17; 95% confidence interval, –5.65 to –0.70; child food security, –1.81; 95% CI, –3.54 to –0.09).
In addition, low/very low compared with high child food security was associated with higher triglycerides (beta, 8.68; 95% CI, 1.75-15.61), higher fasting plasma glucose (beta, 1.37; 95% CI, 0.08-2.65), and metabolic syndrome composite variable expected log counts (beta, 2.12; 95% CI, 0.02-0.45).
Furthermore, the researchers found statistically significant interactions between each of the two food security measures and receipt of any food assistance in the previous year in models of triglycerides (P for interactions: household food security, .03 and child food security, .005) and HDL-C (P for interactions: household food security, .01 and child food security, .04).
After evaluating the effect of parental place of birth, they found a statistically significant association for triglycerides only (P for interactions: household food security, .05 and child food security, .008).
“Our study is among the first to document adverse associations between household and child food security measures with a metabolic syndrome score variable and several metabolic syndrome–relevant cardiometabolic markers among US Hispanic/Latino youth,” the researchers wrote.
The researchers acknowledged that the cross-sectional nature of the study was a key limitation; thus, causality could not be inferred.
“In the future, we plan to conduct more qualitative work to better understand how Hispanic/Latino families respond to food insecurity, which may identify the factors that shape their response,” study author Sandra S. Albrecht, PhD, of Columbia University, New York, NY, said in an interview.
Recommendations for pediatricians
Food insecurity researcher Yankun Wang, PhD candidate at Indiana University, Bloomington, commented: “I would recommend pediatricians pay more attention to children from low-income households since they are more likely to have mental and physical health issues due to food insecurity.
“It can be very helpful if pediatricians could help families obtain SNAP benefits, enroll youth in the school breakfast and lunch programs, and promote nutrition education in schools,” Mr. Wang added.
This study was supported by grant funding from the National Heart, Lung, and Blood Institute. The authors reported no relevant disclosures.

FROM PEDIATRICS
Inside insulin (Part 2): Approaching a cure for type 1 diabetes?
Editor’s note: This is the second in a two-part series commemorating the 100-year anniversary of the first use of insulin in humans. Part 1 of this series examined the rivalry behind the discovery and use of insulin.
One hundred years ago, teenager Leonard Thompson was the first patient with type 1 diabetes to be successfully treated with insulin, granting him a reprieve from what was a certain death sentence at the time.
Since then, research has gathered pace. In the century since insulin’s discovery and first use, recombinant DNA technology has allowed for the engineering of the insulin molecule, providing numerous short- and long-acting analog versions. At the same time, technological leaps in automated insulin delivery and monitoring of blood glucose ensure more time with glucose in range and fewer life-threatening complications for those with type 1 diabetes fortunate enough to have access to the technology.
In spite of these advancements, there is still scope for further evolution of disease management, with the holy grail being the transplant of stem cell–derived islet cells capable of making insulin, ideally encased in some kind of protective device so that immunosuppression is not required.
Indeed, it is not unreasonable to “hope that type 1 diabetes will be a curable disease in the next 100 years,” said Elizabeth Stephens, MD, an endocrinologist who has type 1 diabetes and practices in Portland, Ore.
Type 1 diabetes: The past 100 years
The epidemiology of type 1 diabetes has shifted considerably since 1922. A century ago, given that average life expectancy in the United States was around 54 years, it was pretty much the only type of diabetes that doctors encountered. “There was some type 2 diabetes about in heavier people, but the focus was on type 1 diabetes,” noted Dr. Stephens.
Originally called juvenile diabetes because it was thought to only occur in children, “now 50% of people are diagnosed with type 1 diabetes ... over [the age of] 20,” explained Dr. Stephens.
In the United States, around 1.4 million adults 20 years and older, and 187,000 children younger than 20, have the disease, according to data from the National Diabetes Statistics Report 2020 by the Centers for Disease Control and Prevention. This total represents an increase of nearly 30% from 2017.
Over the years, theories as to the cause, or trigger, for type 1 diabetes “have included cow’s milk and [viral] infections,” said Dr. Stephens. “Most likely, there’s a genetic predisposition and some type of exposure, which creates the perfect storm to trigger disease.”
There are hints that COVID-19 might be precipitating type 1 diabetes in some people. Recently, the CDC found SARS-CoV-2 infection was associated with an increased risk for diabetes (all types) among youth, but not other acute respiratory infections. And two further studies from different parts of the world have recently identified an increase in the incidence of type 1 diabetes in children since the COVID-19 pandemic began, but the reasons remain unclear.
The global CoviDiab registry has also been established to collect data on patients with COVID-19–related diabetes.
The million-dollar question: Is COVID-19 itself is propagating type 1 diabetes or unmasking a predisposition to the disease sooner? The latter might be associated with a lower type 1 diabetes rate in the future, said Partha Kar, MBBS, OBE, national specialty advisor, diabetes, for National Health Service England.
“Right now, we don’t know the answer. Whichever way you look at it, it is likely there will be a rise in cases, and in countries where insulin is not freely available, healthcare systems need to have supply ready because insulin is lifesaving in type 1 diabetes,” Dr. Kar emphasized.
CGMs and automated insulin delivery: A ‘godsend’
A huge change has also been seen, most notably in the past 15 to 20 years, in the technological advancements that can help those with type 1 diabetes live an easier life.
Continuous glucose monitors (CGMs) and automated ways of delivering insulin, such as smart pens and insulin pumps, have made the daily life of a person with type 1 diabetes in the Western world considerably more comfortable.
CGMs provide a constant stream of data to an app, often wirelessly in sync with the insulin pump. However, on a global level, they are only available to a lucky few.
In England, pending National Institute for Health and Care Excellence) approval, any CGM should be available to all eligible patients with type 1 diabetes within the NHS from April 2022, Dr. Kar pointed out. In the United States, CGMs are often unaffordable and access is mostly dependent on a person’s health insurance.
Kersten Hall, PhD, a scientist and U.K.-based medical historian who recently wrote a book, “Insulin, the Crooked Timber” (Oxford, England: Oxford University Press, 2022) uncovering the lesser-known story behind the discovery of insulin, was diagnosed with adult-onset type 1 diabetes at the age of 41. Dr. Hall had always found the finger-prick blood glucose test to be a chore but now has a CGM.
“It’s a total game changer for me: a godsend. I can’t sing its praises enough,” he said. “All it involves is the swipe of the phone and this provides a reading which tells me if my glucose is too low, so I eat something, or too high, so I might [go for] a run.”
Brewing insulin at scale
As described by Dr. Hall in his book, the journey from treating Mr. Thompson in 1922 to treating the masses began when biochemist James Collip, MD, PhD, discovered a means of purifying the animal pancreas extracts used to treat the teenager.
But production at scale presented a further challenge. This was overcome in 1924 when Eli Lilly drew on a technique used in the beer brewing process – where pH guides bitterness – to purify and manufacture large amounts of insulin.
By 1936, a range of slower-acting cattle and pig-derived insulins, the first produced by Novo Nordisk Pharmaceuticals, were developed.
However, it took 8,000 lb (approximately 3,600 kg) of pancreas glands from 23,500 animals to make 1 lb (0.5 kg) of insulin, so a more efficient process was badly needed.
Dr. Hall, who is a molecular biologist as well as an author, explains that the use of recombinant DNA technology to produce human insulin, as done by Genentech in the late 70s, was a key development in the story of modern insulin products. Genentech then provided synthetic human insulin for Eli Lilly to conduct clinical trials.
Human insulin most closely resembles porcine insulin structure and function, differing by only one amino acid, while human insulin differs from bovine insulin by three amino acid residues. This synthetic human insulin eliminated the allergies that the animal-derived products sometimes caused.
In the early 1980s, Eli Lilly produced Humulin, the first biosynthetic (made in Escherichia coli, hence the term, “bio”) human insulin.
This technology eventually “allowed for the alteration of specific amino acids in the sequence of the insulin protein to make insulin analogs [synthetic versions grown in E. coli and genetically altered for various properties] that act faster, or more slowly, than normal human insulin. By using the slow- and fast-acting insulins in combination, a patient can control their blood sugar levels with a much greater degree of finesse and precision,” Dr. Hall explained.
Today, a whole range of insulins are available, including ultra–rapid-acting, short-acting, intermediate-acting, long-acting, ultra–long-acting, and even inhaled insulin, although the latter is expensive, has been associated with side effects, and is less commonly used, according to Dr. Stephens.
Oral insulin formulations are even in the early stages of development, with candidate drugs by Generex and from the Oralis project.
“With insulin therapy, we try to reproduce the normal physiology of the healthy body and pancreas,” Dr. Stephens explained.
Insulin analogs are only made by three companies (Eli Lilly, Novo Nordisk, and Sanofi), and they are generally much more expensive than nonanalog human insulin. In the United Kingdom through the NHS, they cost twice as much.
In the United States today, one of the biggest barriers to proper care of type 1 diabetes is the cost of insulin, which can limit access. With the market controlled by these three large companies, the average cost of a unit of insulin in the United States, according to RAND research, was $98.17 in January 2021, compared with $7.52 in the United Kingdom and $12.00 in Canada.
Several U.S. states have enacted legislation capping insulin copayments to at, or under, $100 a month. But the federal Build Back Better Framework Act – which would cap copayments for insulin at $35 – currently hangs in the balance.
Alongside these moves, in 2020 the Food and Drug Administration approved the first interchangeable biosimilar insulin for type 1 diabetes (and insulin-dependent type 2 diabetes) in children and adults, called Semglee (Mylan Pharmaceuticals).
Biosimilars (essentially generic versions of branded insulins) are expected to be less expensive than branded analogs, but the indications so far are that they will only be around 20% cheaper.
“I totally fail to understand how the richest country in the world still has a debate about price caps, and we are looking at biosimilar markets to change the debate. This makes no sense to me at all,” stressed Dr. Kar. “For lifesaving drugs, they should be funded by the state.”
Insulin also remains unaffordable for many in numerous low- and middle-income countries, where most patients pay out-of-pocket for medicines. Globally, there are estimated to be around 30 million people who need insulin but cannot afford it.
How near to a cure in the coming decades?
Looking ahead to the coming years, if not the next 100, Dr. Stephens highlighted two important aspects of care.
First, the use of a CGM device in combination with an insulin pump (also known as a closed-loop system or artificial pancreas), where the CGM effectively tells the insulin pump how much insulin to automatically dispense, should revolutionize care.
A number of such closed-loop systems have recently been approved in both the United States, including systems from Medtronic and Omnipod, and Europe.
“I wear one of these and it’s been a life changer for me, but it doesn’t suit everyone because the technology can be cumbersome, but with time, hopefully things will become smaller and more accurate in insulin delivery,” Dr. Stephens added.
The second advance of interest is the development and transplantation of cells that produce insulin.
Dr. Stephens explained that someone living with type 1 diabetes has a lot to think about, not least, doing the math related to insulin requirement. “If we just had cells from a pancreas that could be transplanted and would do that for us, then it would be a total game changer.”
To date, Vertex Pharmaceuticals has successfully treated one patient – who had lived with type 1 diabetes for about 40 years and had recurrent episodes of severe hypoglycemia – with an infusion of stem cell–derived differentiated islet cells into his liver. The procedure resulted in near reversal of type 1 diabetes, with his insulin dose reduced from 34 to 3 units, and his hemoglobin A1c falling from 8.6% to 7.2%.
And although the patient, Brian Shelton, still needs to take immunosuppressive agents to prevent rejection of the stem cell–derived islets, “it’s a whole new life,” he recently told the New York Times.
Another company called ViaCyte is also working on a similar approach.
Whether this is a cure for type 1 diabetes is still debatable, said Anne Peters, MD, of the University of Southern California, Los Angeles. “Is it true? In a word, no. But we are part of the way there, which is much closer than we were 6 months ago.”
There are also ongoing clinical trials of therapeutic interventions to prevent or delay the trajectory from presymptomatic to clinical type 1 diabetes. The most advanced is the anti-CD3 monoclonal antibody teplizumab (Tzield, Provention Bio), which was rejected by the FDA in July 2021, but has since been refiled. The company expects to hear from the agency by the end of March 2022 as to whether the resubmission has been accepted.
Diabetes specialist nurses/educators keep it human
Dr. Hall said he concurs with the late eminent U.K. diabetes specialist Robert Tattersall’s observation on what he considers one of the most important advances in the management and treatment of type 1 diabetes: the human touch.
Referring to Dr. Tattersall’s book, “Diabetes: A Biography,” Dr. Hall quoted: “If asked what innovation had made the most difference to their lives in the 1980s, patients with type 1 diabetes in England would unhesitatingly have chosen not human insulin, but the spread of diabetes specialist nurses ... these people (mainly women) did more in the last two decades of the 20th century to improve the standard of diabetes care than any other innovation or drug.”
In the United States, diabetes specialist nurses were called diabetes educators until recently, when the name changed to certified diabetes care and education specialist.
“Above all, they have humanized the service and given the patient a say in the otherwise unequal relationship with all-powerful doctors,” concluded Dr. Hall, again quoting Dr. Tattersall.

In spite of these advancements, there is still scope for further evolution of disease management, with the holy grail being the transplant of stem cell–derived islet cells capable of making insulin, ideally encased in some kind of protective device so that immunosuppression is not required.
Indeed, it is not unreasonable to “hope that type 1 diabetes will be a curable disease in the next 100 years,” said Elizabeth Stephens, MD, an endocrinologist who has type 1 diabetes and practices in Portland, Ore.
Type 1 diabetes: The past 100 years
The epidemiology of type 1 diabetes has shifted considerably since 1922. A century ago, given that average life expectancy in the United States was around 54 years, it was pretty much the only type of diabetes that doctors encountered. “There was some type 2 diabetes about in heavier people, but the focus was on type 1 diabetes,” noted Dr. Stephens.
Originally called juvenile diabetes because it was thought to only occur in children, “now 50% of people are diagnosed with type 1 diabetes ... over [the age of] 20,” explained Dr. Stephens.
In the United States, around 1.4 million adults 20 years and older, and 187,000 children younger than 20, have the disease, according to data from the National Diabetes Statistics Report 2020 by the Centers for Disease Control and Prevention. This total represents an increase of nearly 30% from 2017.
Over the years, theories as to the cause, or trigger, for type 1 diabetes “have included cow’s milk and [viral] infections,” said Dr. Stephens. “Most likely, there’s a genetic predisposition and some type of exposure, which creates the perfect storm to trigger disease.”
There are hints that COVID-19 might be precipitating type 1 diabetes in some people. Recently, the CDC found SARS-CoV-2 infection was associated with an increased risk for diabetes (all types) among youth, but not other acute respiratory infections. And two further studies from different parts of the world have recently identified an increase in the incidence of type 1 diabetes in children since the COVID-19 pandemic began, but the reasons remain unclear.
The global CoviDiab registry has also been established to collect data on patients with COVID-19–related diabetes.
The million-dollar question: Is COVID-19 itself is propagating type 1 diabetes or unmasking a predisposition to the disease sooner? The latter might be associated with a lower type 1 diabetes rate in the future, said Partha Kar, MBBS, OBE, national specialty advisor, diabetes, for National Health Service England.
“Right now, we don’t know the answer. Whichever way you look at it, it is likely there will be a rise in cases, and in countries where insulin is not freely available, healthcare systems need to have supply ready because insulin is lifesaving in type 1 diabetes,” Dr. Kar emphasized.
CGMs and automated insulin delivery: A ‘godsend’
A huge change has also been seen, most notably in the past 15 to 20 years, in the technological advancements that can help those with type 1 diabetes live an easier life.
Continuous glucose monitors (CGMs) and automated ways of delivering insulin, such as smart pens and insulin pumps, have made the daily life of a person with type 1 diabetes in the Western world considerably more comfortable.
CGMs provide a constant stream of data to an app, often wirelessly in sync with the insulin pump. However, on a global level, they are only available to a lucky few.
In England, pending National Institute for Health and Care Excellence) approval, any CGM should be available to all eligible patients with type 1 diabetes within the NHS from April 2022, Dr. Kar pointed out. In the United States, CGMs are often unaffordable and access is mostly dependent on a person’s health insurance.
Kersten Hall, PhD, a scientist and U.K.-based medical historian who recently wrote a book, “Insulin, the Crooked Timber” (Oxford, England: Oxford University Press, 2022) uncovering the lesser-known story behind the discovery of insulin, was diagnosed with adult-onset type 1 diabetes at the age of 41. Dr. Hall had always found the finger-prick blood glucose test to be a chore but now has a CGM.
“It’s a total game changer for me: a godsend. I can’t sing its praises enough,” he said. “All it involves is the swipe of the phone and this provides a reading which tells me if my glucose is too low, so I eat something, or too high, so I might [go for] a run.”
Brewing insulin at scale
As described by Dr. Hall in his book, the journey from treating Mr. Thompson in 1922 to treating the masses began when biochemist James Collip, MD, PhD, discovered a means of purifying the animal pancreas extracts used to treat the teenager.
But production at scale presented a further challenge. This was overcome in 1924 when Eli Lilly drew on a technique used in the beer brewing process – where pH guides bitterness – to purify and manufacture large amounts of insulin.
By 1936, a range of slower-acting cattle and pig-derived insulins, the first produced by Novo Nordisk Pharmaceuticals, were developed.
However, it took 8,000 lb (approximately 3,600 kg) of pancreas glands from 23,500 animals to make 1 lb (0.5 kg) of insulin, so a more efficient process was badly needed.
Dr. Hall, who is a molecular biologist as well as an author, explains that the use of recombinant DNA technology to produce human insulin, as done by Genentech in the late 70s, was a key development in the story of modern insulin products. Genentech then provided synthetic human insulin for Eli Lilly to conduct clinical trials.
Human insulin most closely resembles porcine insulin structure and function, differing by only one amino acid, while human insulin differs from bovine insulin by three amino acid residues. This synthetic human insulin eliminated the allergies that the animal-derived products sometimes caused.
In the early 1980s, Eli Lilly produced Humulin, the first biosynthetic (made in Escherichia coli, hence the term, “bio”) human insulin.
This technology eventually “allowed for the alteration of specific amino acids in the sequence of the insulin protein to make insulin analogs [synthetic versions grown in E. coli and genetically altered for various properties] that act faster, or more slowly, than normal human insulin. By using the slow- and fast-acting insulins in combination, a patient can control their blood sugar levels with a much greater degree of finesse and precision,” Dr. Hall explained.
Today, a whole range of insulins are available, including ultra–rapid-acting, short-acting, intermediate-acting, long-acting, ultra–long-acting, and even inhaled insulin, although the latter is expensive, has been associated with side effects, and is less commonly used, according to Dr. Stephens.
Oral insulin formulations are even in the early stages of development, with candidate drugs by Generex and from the Oralis project.
“With insulin therapy, we try to reproduce the normal physiology of the healthy body and pancreas,” Dr. Stephens explained.
Insulin analogs are only made by three companies (Eli Lilly, Novo Nordisk, and Sanofi), and they are generally much more expensive than nonanalog human insulin. In the United Kingdom through the NHS, they cost twice as much.
In the United States today, one of the biggest barriers to proper care of type 1 diabetes is the cost of insulin, which can limit access. With the market controlled by these three large companies, the average cost of a unit of insulin in the United States, according to RAND research, was $98.17 in January 2021, compared with $7.52 in the United Kingdom and $12.00 in Canada.
Several U.S. states have enacted legislation capping insulin copayments to at, or under, $100 a month. But the federal Build Back Better Framework Act – which would cap copayments for insulin at $35 – currently hangs in the balance.
Alongside these moves, in 2020 the Food and Drug Administration approved the first interchangeable biosimilar insulin for type 1 diabetes (and insulin-dependent type 2 diabetes) in children and adults, called Semglee (Mylan Pharmaceuticals).
Biosimilars (essentially generic versions of branded insulins) are expected to be less expensive than branded analogs, but the indications so far are that they will only be around 20% cheaper.
“I totally fail to understand how the richest country in the world still has a debate about price caps, and we are looking at biosimilar markets to change the debate. This makes no sense to me at all,” stressed Dr. Kar. “For lifesaving drugs, they should be funded by the state.”
Insulin also remains unaffordable for many in numerous low- and middle-income countries, where most patients pay out-of-pocket for medicines. Globally, there are estimated to be around 30 million people who need insulin but cannot afford it.
How near to a cure in the coming decades?
Looking ahead to the coming years, if not the next 100, Dr. Stephens highlighted two important aspects of care.
First, the use of a CGM device in combination with an insulin pump (also known as a closed-loop system or artificial pancreas), where the CGM effectively tells the insulin pump how much insulin to automatically dispense, should revolutionize care.
A number of such closed-loop systems have recently been approved in both the United States, including systems from Medtronic and Omnipod, and Europe.
“I wear one of these and it’s been a life changer for me, but it doesn’t suit everyone because the technology can be cumbersome, but with time, hopefully things will become smaller and more accurate in insulin delivery,” Dr. Stephens added.
The second advance of interest is the development and transplantation of cells that produce insulin.
Dr. Stephens explained that someone living with type 1 diabetes has a lot to think about, not least, doing the math related to insulin requirement. “If we just had cells from a pancreas that could be transplanted and would do that for us, then it would be a total game changer.”
To date, Vertex Pharmaceuticals has successfully treated one patient – who had lived with type 1 diabetes for about 40 years and had recurrent episodes of severe hypoglycemia – with an infusion of stem cell–derived differentiated islet cells into his liver. The procedure resulted in near reversal of type 1 diabetes, with his insulin dose reduced from 34 to 3 units, and his hemoglobin A1c falling from 8.6% to 7.2%.
And although the patient, Brian Shelton, still needs to take immunosuppressive agents to prevent rejection of the stem cell–derived islets, “it’s a whole new life,” he recently told the New York Times.
Another company called ViaCyte is also working on a similar approach.
Whether this is a cure for type 1 diabetes is still debatable, said Anne Peters, MD, of the University of Southern California, Los Angeles. “Is it true? In a word, no. But we are part of the way there, which is much closer than we were 6 months ago.”
There are also ongoing clinical trials of therapeutic interventions to prevent or delay the trajectory from presymptomatic to clinical type 1 diabetes. The most advanced is the anti-CD3 monoclonal antibody teplizumab (Tzield, Provention Bio), which was rejected by the FDA in July 2021, but has since been refiled. The company expects to hear from the agency by the end of March 2022 as to whether the resubmission has been accepted.
Diabetes specialist nurses/educators keep it human
Dr. Hall said he concurs with the late eminent U.K. diabetes specialist Robert Tattersall’s observation on what he considers one of the most important advances in the management and treatment of type 1 diabetes: the human touch.
Referring to Dr. Tattersall’s book, “Diabetes: A Biography,” Dr. Hall quoted: “If asked what innovation had made the most difference to their lives in the 1980s, patients with type 1 diabetes in England would unhesitatingly have chosen not human insulin, but the spread of diabetes specialist nurses ... these people (mainly women) did more in the last two decades of the 20th century to improve the standard of diabetes care than any other innovation or drug.”
In the United States, diabetes specialist nurses were called diabetes educators until recently, when the name changed to certified diabetes care and education specialist.
“Above all, they have humanized the service and given the patient a say in the otherwise unequal relationship with all-powerful doctors,” concluded Dr. Hall, again quoting Dr. Tattersall.

Editor’s note: This is the second in a two-part series commemorating the 100-year anniversary of the first use of insulin in humans. Part 1 of this series examined the rivalry behind the discovery and use of insulin.
One hundred years ago, teenager Leonard Thompson was the first patient with type 1 diabetes to be successfully treated with insulin, granting him a reprieve from what was a certain death sentence at the time.
Since then, research has gathered pace. In the century since insulin’s discovery and first use, recombinant DNA technology has allowed for the engineering of the insulin molecule, providing numerous short- and long-acting analog versions. At the same time, technological leaps in automated insulin delivery and monitoring of blood glucose ensure more time with glucose in range and fewer life-threatening complications for those with type 1 diabetes fortunate enough to have access to the technology.

CPAP has only small effect on metabolic syndrome
Continuous positive airway pressure (CPAP) may be only modestly effective for ameliorating metabolic syndrome in patients with moderate to severe obstructive sleep apnea (OSA).
That conclusion comes from investigators in a randomized controlled, trial, who found that, among 100 patients with OSA and a recent diagnosis of metabolic syndrome (MS), 18% of those assigned to use CPAP at night had a reversal of MS at 6 months of follow-up, compared with 4% of controls who were assigned to use nasal strips at night (P = .04).
The majority of patients assigned to CPAP still retained their MS diagnoses at 6 months, and CPAP did not significantly reduce individual components of the syndrome. Use of CPAP was, however, associated with small reductions in visceral fat and improvement in endothelial function, reported Sara Q.C. Giampa, PhD, from the University of São Paulo, and colleagues.
“Despite a significant rate of MS reversibility after CPAP therapy, most of the patients maintained the MS diagnosis. The modest effects of CPAP on MS reversibility underscore the need for combined therapy with CPAP, aiming to maximize metabolic syndrome recovery in parallel with improvements in OSA severity and related symptoms,” according to their study, reported in the journal CHEST®.
Asked whether he still recommends CPAP to patients with OSA and the metabolic syndrome, given the findings, corresponding author Luciano F. Drager, MD, PhD, replied “yes, definitely.”
“Despite the modest rate in reversing metabolic syndrome after CPAP, the rate was 5-fold higher than non-effective treatment (18% vs. 4%),” he said in an interview.
Dr. Drager noted that studies of other single interventions such as physical exercise to reverse MS in patients with OSA also had modest results.
A researcher who studies the relationship between sleep, circadian rhythms, and metabolism commented that, although the patients in the CPAP group were compliant with the assigned equipment and had both reductions in apneic events and improvement in oxygen saturation, the effect of CPAP on the metabolic syndrome was rather small.
“The CPAP was doing what we thought it was supposed to do, but it didn’t have the magnitude of effect on the metabolic syndrome as I expected or I think as the authors expected,” said Deanna Arble, PhD, assistant professor of biological science at Marquette University, Milwaukee.
She noted that the study also failed to detect a significant improvement in the blood pressure component of metabolic syndrome.
“In my experience and my review of the literature, blood pressure tends to be the one that’s improved most dramatically with CPAP,” she said.
Dr. Arble was not involved in the study.
Study details
In the trial, titled TREATOSA-MS, the investigators enrolled 100 patients with a recent diagnosis of metabolic syndrome and moderate to severe OSA, defined as 15 or more apnea-hypopnea index events per hour. The patients were stratified by body mass index and then randomized to undergo therapeutic CPAP or to use nasal strips for 6 months.
At baseline and at the end of each intervention investigators measured anthropometric variables, blood pressure, glucose, and lipid profiles. They also leptin and adiponectin, body composition, food intake, physical activity, subcutaneous and abdominal fat (visceral and hepatic), and endothelial function to control for potential confounders.
As noted previously, they found that after 6 months “most patients with OSA randomized to CPAP retained the MS diagnosis, but the rate of MS reversibility was higher than observed in the placebo group.” The difference in metabolic syndrome reversal, 18% with CPAP versus 4% with nasal strips, translated into a hazard ratio favoring CPAP of 5.27 (P = .04).
Also as noted, in analyses adjusted for baseline values, CPAP did not significantly improve either weight, liver fat, lip profiles, or the adiposity biomarkers leptin and adiponectin, but did have “very modest” influence on reducing visceral fat and improving endothelial function.
Rigorous study
Dr. Arble said that most studies of the association between OSA and metabolic syndrome have focused on only one or two of the parameters that were included in the TREATOSA-MS study, giving the findings additional weight.
“This could potentially be a very good, carefully controlled first insight into how obstructive sleep apnea is related to the metabolic syndrome,” she said.
The study was funded by grants Fundação de Amparo Q22 à Pesquisa do Estado de São Paulo and Coordenação de Aperfeiçoamento de Pessoal de Nível Superior. The authors and Dr. Arble reported having no conflicts of interest to disclose.

The majority of patients assigned to CPAP still retained their MS diagnoses at 6 months, and CPAP did not significantly reduce individual components of the syndrome. Use of CPAP was, however, associated with small reductions in visceral fat and improvement in endothelial function, reported Sara Q.C. Giampa, PhD, from the University of São Paulo, and colleagues.
“Despite a significant rate of MS reversibility after CPAP therapy, most of the patients maintained the MS diagnosis. The modest effects of CPAP on MS reversibility underscore the need for combined therapy with CPAP, aiming to maximize metabolic syndrome recovery in parallel with improvements in OSA severity and related symptoms,” according to their study, reported in the journal CHEST®.
Asked whether he still recommends CPAP to patients with OSA and the metabolic syndrome, given the findings, corresponding author Luciano F. Drager, MD, PhD, replied “yes, definitely.”
“Despite the modest rate in reversing metabolic syndrome after CPAP, the rate was 5-fold higher than non-effective treatment (18% vs. 4%),” he said in an interview.
Dr. Drager noted that studies of other single interventions such as physical exercise to reverse MS in patients with OSA also had modest results.
A researcher who studies the relationship between sleep, circadian rhythms, and metabolism commented that, although the patients in the CPAP group were compliant with the assigned equipment and had both reductions in apneic events and improvement in oxygen saturation, the effect of CPAP on the metabolic syndrome was rather small.
“The CPAP was doing what we thought it was supposed to do, but it didn’t have the magnitude of effect on the metabolic syndrome as I expected or I think as the authors expected,” said Deanna Arble, PhD, assistant professor of biological science at Marquette University, Milwaukee.
She noted that the study also failed to detect a significant improvement in the blood pressure component of metabolic syndrome.
“In my experience and my review of the literature, blood pressure tends to be the one that’s improved most dramatically with CPAP,” she said.
Dr. Arble was not involved in the study.
Study details
In the trial, titled TREATOSA-MS, the investigators enrolled 100 patients with a recent diagnosis of metabolic syndrome and moderate to severe OSA, defined as 15 or more apnea-hypopnea index events per hour. The patients were stratified by body mass index and then randomized to undergo therapeutic CPAP or to use nasal strips for 6 months.
At baseline and at the end of each intervention investigators measured anthropometric variables, blood pressure, glucose, and lipid profiles. They also leptin and adiponectin, body composition, food intake, physical activity, subcutaneous and abdominal fat (visceral and hepatic), and endothelial function to control for potential confounders.
As noted previously, they found that after 6 months “most patients with OSA randomized to CPAP retained the MS diagnosis, but the rate of MS reversibility was higher than observed in the placebo group.” The difference in metabolic syndrome reversal, 18% with CPAP versus 4% with nasal strips, translated into a hazard ratio favoring CPAP of 5.27 (P = .04).
Also as noted, in analyses adjusted for baseline values, CPAP did not significantly improve either weight, liver fat, lip profiles, or the adiposity biomarkers leptin and adiponectin, but did have “very modest” influence on reducing visceral fat and improving endothelial function.
Rigorous study
Dr. Arble said that most studies of the association between OSA and metabolic syndrome have focused on only one or two of the parameters that were included in the TREATOSA-MS study, giving the findings additional weight.
“This could potentially be a very good, carefully controlled first insight into how obstructive sleep apnea is related to the metabolic syndrome,” she said.
The study was funded by grants Fundação de Amparo Q22 à Pesquisa do Estado de São Paulo and Coordenação de Aperfeiçoamento de Pessoal de Nível Superior. The authors and Dr. Arble reported having no conflicts of interest to disclose.

Ukrainian diabetes care, insulin access ‘severely disrupted’
with shortages resulting more from distribution problems than supply itself, according to multiple sources.
In 2021, there were about 2.3 million people with diabetes in Ukraine, roughly 7% of the total population. Of those, about 120,000 have type 1 diabetes and depend on insulin to live, while a similar number have insulin-treated type 2 diabetes.
Donations of insulin, other medications, and supplies have been pouring in since late February from sources including the Ukrainian diaspora, nongovernmental organizations, other European governments, universities, and product manufacturers. “The main problem now is logistic,” Boris Mankovsky, MD, president of the Ukrainian Diabetology Association, said in an interview.
Insulin manufacturer Novo Nordisk’s warehouse continues to operate, although deliveries have been curtailed because of shortages in delivery staff. The company is working to get medications to patients either through pharmacies or humanitarian organizations and has funded refugee support efforts, they said in a March 8 statement.
But even if the supplies reach the pharmacies, they may not reach patients for a variety of logistical reasons, noted Dr. Mankovsky, who is head of the department of diabetology at the P.L. Shupyk National Medical Academy for Postgraduate Education in Kyiv. “So, there are a lot of problems. I don’t know exactly where the main bottleneck is, but there are shortages, definitely.”
Insulin supplies have also been distributed very unequally by region and type, with various shipments containing long-acting, short-acting, analog, or human insulins. “We’re very grateful for all of it. But it’s not centrally coordinated, which of course is understandable, but it means that a lot of donations go to one place and no supply goes to another,” Dr. Mankovsky said.
Most of the donated supplies have been going to western Ukraine, where the capital Kyiv is located. “But the main problem now is the eastern part of Ukraine. It’s difficult and dangerous to deliver any supplies there, especially [with] the terrible situation in Mariupol. Eastern Ukraine now suffers the most, at least at this minute,” he said.
Diabetes specialists continue to work, at least for now
Ivan Smirnov, MD, PhD, head of the endocrinology department at Kharkiv Regional Hospital, in the northeastern part of the country, said in an email to this news organization: “I continue to stay in Kharkiv, in spite of the situation. A lot of people are killed, many people are wounded. My hospital is full of wounded civilians ... a lot of buildings are destroyed partly and some completely.”
Dr. Smirnov said that he and his colleagues “find the way to overcome the fear ... in constant work. Part of the work is online consulting assistance for routine patients. ... But the main time now is dedicated to providing the diabetes patients with insulin. This is a heavy job to do indeed.”
Dr. Mankovsky, who practices adult diabetology and endocrinology in Kyiv, continues to manage patients, but mostly remotely. “Practice is severely disrupted. I’m willing to see patients but it’s extremely difficult and dangerous for them and probably not possible to travel to see me. So that’s why all our communications now is distant, through phone or internet. ... We can communicate and I’m able to provide some recommendations for changes in treatment or some corrections in insulin therapy.”
Despite the Russians closing in on Kyiv, Dr. Mankovsky said, “I’ve decided to stay as long as possible. Then, nobody knows of course but I think I have to. ... We hear explosions every day. ... I’m in the center of the city and the streets are empty. It’s heartbreaking.”
Supplies are reaching refugees
Dr. Mankovsky said: “Now we have huge movement of refugees. Among them are a lot of people with diabetes who moved out of their place and nobody knows where they are. It’s really a huge disruption.”
According to the type 1 diabetes advocacy organization JDRF, many men with diabetes aged 18-60 are remaining in Ukraine to fight, despite the increased risk with the disease. But an estimated 15,000 children with type 1 diabetes and their families are attempting to escape the conflict by moving to the western regions of the country or over the borders.
“Those who make it to Hungary, Moldova, Poland, or Romania are being received with wonderful generosity. We have heard stories ranging from governments making it possible to pick up insulin free without a script to individuals emptying their cupboards of insulin for those whose need is urgent,” JDRF said in a statement on March 2.
For its part, Novo Nordisk has donated 55 million Danish kroner (about 7.3 million Euros, or $8.2 million U.S. dollars) to support international relief organizations in assisting refugees.
Ivan Tkac, MD, PhD, professor of medicine at Safárik University in Kosice, Slovakia, is assisting refugees, including those with diabetes. Slovakia is predominantly a transit country for refugees from Ukraine, he said in an interview.
“However, in solidarity with Ukraine, we are providing emergency medical care for both Ukrainians and refugees from third countries leaving Ukraine,” he said, noting that those individuals are primarily foreign students who had been studying there.
“Asylum seekers receive full medical insurance paid by the government of the Slovak Republic. As part of this care, the refugees are provided with the necessary amount of insulin and other antidiabetic drugs, as well as medical devices needed for the treatment of diabetes. The European Commission has pledged to supply Slovakia with the necessary quantities of medicines for the treatment of diabetes in the coming weeks as part of its assistance to the countries bordering Ukraine. In addition, some humanitarian organizations are organizing supplies of insulin and other medicines for soldiers fighting in the Ukrainian army,” Dr. Tkac said.
How you can help
A number of organizations are providing assistance specifically to people with diabetes, as well as broader medical assistance to people remaining in Ukraine and to refugees.
A collaboration between the Ministry of Health of Ukraine, the humanitarian agency Direct Relief, and the International Diabetes Federation is working to determine where supplies are short, to secure donations within Europe, and to open up “green corridors” within Ukraine to deliver them quickly to where they’re needed. They have asked those who wish to help to donate to Direct Relief and direct donations to the “Ukraine crisis.”
Another effort organized by IDF Europe is Connect Solidarity, a program that “aims to facilitate support from IDF Europe member associations across Europe wishing to help other national diabetes associations in Ukraine’s neighboring countries, provide advice, medicines, and supplies to Ukrainian refugees.”
IDF President Andrew Boulton, MD, told this news organization that he has been in almost daily contact with senior colleagues working in diabetes in Ukraine, and that he is working with the organization’s affiliated charity Life for a Child in addition to the other charitable agencies. “We will continue to do our utmost best to help those with diabetes living in Ukraine. However, this is, of course, very challenging, and we hope that we are doing the best we can in such a difficult situation. We all hope and pray that this situation is soon resolved.”
The European Association for the Study of Diabetes is taking a somewhat different approach, by encouraging its members to “support people with ill health, including diabetes, with donations through established [nongovernmental organizations] that have the capacity to help on site, such as United Nations High Commissioner for Refugees or International Committee of the Red Cross.”
Dr. Mankovsky told this news organization that he is very grateful for all the support from around the world: “Just thanks. I’ve got so much support, so many phone calls, so many letters ... not just me, all of us. People wise and friendship wise we feel support. It’s really important, emotionally and with insulin supply and other medications. Without that, it would be much more difficult.”
Pandemic-prompted changes enable wartime diabetes care
Dramatic changes in diabetes care delivery in Ukraine necessitated by the COVID-19 pandemic have proved indispensable during the Russian invasion.
In a piece published May 29, 2020, in the Journal of Diabetes Science and Technology, Dr. Mankovsky described how the pandemic hit just as Ukraine’s health system was pivoting from government controlled to insurance based.
Prior to the pandemic, patients with both type 1 and type 2 diabetes were regularly admitted to hospital for routine checkups, insulin dose management, and other treatments, a “remnant of the Soviet-era medical practice, which emphasized heavily on hospital admissions,” Dr. Mankovsky said in an interview.
This was the case, he wrote in the article, “despite the common understanding that such a system was a waste of resources ... this policy was changing much slower than we wanted.”
But the COVID-19 pandemic changed that practice “abruptly and dramatically,” so that all hospitalizations for patients with diabetes were stopped unless there was a real metabolic emergency.
Subsequently, Dr. Mankovsky wrote, “almost every health professional recognizes the particular importance of the new ways of communications with patients and with other colleagues.”
Indeed, in his email to this news organization, Dr. Smirnov mentioned that the routine diabetes management work he is still able to do remotely despite the extreme disruption in his region “is easy because of long-term COVID-period experience.”
Also because of the pandemic, insulin prescriptions were switched from traditional paper to electronic transfer, so that patients could easily pick them up at the pharmacy. “This new ... system proved to be not just very convenient for all parties involved, but in the current situation, it allowed us to prevent so many medically unnecessary visits to the clinics, which otherwise would have presented the real threat to the patients’ health and risk to get them infected,” Dr. Mankovsky wrote in 2020.
Now with the new danger, he said, “the inability to see patients is probably the least of our problems.”

Can a tool help overcome barriers to diabetes medication cost?
The resource, “Having Healthcare Cost Conversations to Improve Patient Outcomes: A Practical Guide,” was jointly developed by the Association of Diabetes Care & Education Specialists and Beyond Type 1, the nonprofit patient advocacy organization.
Indeed, the guide appeared as President Biden discussed his proposal to cap insulin costs at $35 per insulin vial during the State of the Union address, during which he introduced a young boy with type 1 diabetes in the guest box, as reported by this news organization. On March 3, Civica, a nonprofit coalition of health systems and philanthropies, announced it plans to manufacture generic insulin at a deeply discounted price, as reported by this news organization.
“Just to see diabetes front and center at the State of the Union followed by these announcements is certainly reflective of our own advocacy effort to make sure that people have affordable options for insulin, diabetes medications, services,” Kate Thomas, ADCES chief advocacy and external affairs officer, said in an interview. She added that ADCES has also pushed for legislation in Congress that would expand access to diabetes self-management training under the Medicare program.
The guide includes advice about overcoming barriers to discussing treatment costs with patients, suggested questions to ask patients about specific costs, and determinants of health and conversational approaches. Links are provided to resources for obtaining affordable insulin, other diabetes medications, and continuous glucose monitoring and insulin pump equipment.
“We know that, especially during primary care visits, there is limited time along with numbers of issues to talk about, so I think our challenge is how do we prioritize these conversations with something that can lead to action, not just saying you should do this but how do you actually do it,” Ms. Thomas said.
The introduction summarizes results from a 2021 Beyond Type 1 survey confirming prior findings reported by this news organization that cost is a frequent barrier for many individuals living with diabetes. “Especially right now where we are in terms of the impact of the pandemic and with peoples’ job statuses changing, I think it’s worthwhile to raise this in patient encounters,” Ms. Thomas said.
Overcoming conversational barriers
The first of three tables in the guide provides a list of “barriers to having a cost conversation” in the first column and “suggested solutions” in the second. For example, for the barrier, “You have insufficient time and/or knowledge about cost,” the suggestion is, “request and share available faculty and resources, including benefits coordinators, social workers, and community-based organizations. Work with the pharmacists and other members of the diabetes care team to identify resources that lower cost of medications.”
And for another barrier, “patients are often embarrassed or ashamed to initiate discussions of affordability,” the suggested solution is: “Normalize the issue of cost of care barriers for patients.”
A second table offers specific questions to ask patients about costs of medications and care, determinants of health, and financial barriers. These include: “What are some challenges you’ve had to accessing your medications or taking them as prescribed? What are some out-of-pocket health care costs you need help with? What challenges do you have accessing healthy food for you and your family?”
A link to a screening tool for social determinants of health is also included.
Language suggestions include talking about “cost of care” rather than “money,” asking patients if they’ve understood everything correctly by repeating back what they’ve said, and asking for confirmation and discussing follow-up.
Overall, the tool is designed to be a “broad conversation starter,” and not just about medications, Ms. Thomas said. “This is for all audiences and it’s meant to be something that the provider can tailor depending on who they’re speaking to. ... It’s about medications, but also the entire cost of care, including services and devices, transportation to appointments, access to food. ... Diabetes care isn’t just taking medication. It’s so many more factors.”
Ms. Thomas reported no relevant financial relationships.

The resource, “Having Healthcare Cost Conversations to Improve Patient Outcomes: A Practical Guide,” was jointly developed by the Association of Diabetes Care & Education Specialists and Beyond Type 1, the nonprofit patient advocacy organization.
Indeed, the guide appeared as President Biden discussed his proposal to cap insulin costs at $35 per insulin vial during the State of the Union address, during which he introduced a young boy with type 1 diabetes in the guest box, as reported by this news organization. On March 3, Civica, a nonprofit coalition of health systems and philanthropies, announced it plans to manufacture generic insulin at a deeply discounted price, as reported by this news organization.
“Just to see diabetes front and center at the State of the Union followed by these announcements is certainly reflective of our own advocacy effort to make sure that people have affordable options for insulin, diabetes medications, services,” Kate Thomas, ADCES chief advocacy and external affairs officer, said in an interview. She added that ADCES has also pushed for legislation in Congress that would expand access to diabetes self-management training under the Medicare program.
The guide includes advice about overcoming barriers to discussing treatment costs with patients, suggested questions to ask patients about specific costs, and determinants of health and conversational approaches. Links are provided to resources for obtaining affordable insulin, other diabetes medications, and continuous glucose monitoring and insulin pump equipment.
“We know that, especially during primary care visits, there is limited time along with numbers of issues to talk about, so I think our challenge is how do we prioritize these conversations with something that can lead to action, not just saying you should do this but how do you actually do it,” Ms. Thomas said.
The introduction summarizes results from a 2021 Beyond Type 1 survey confirming prior findings reported by this news organization that cost is a frequent barrier for many individuals living with diabetes. “Especially right now where we are in terms of the impact of the pandemic and with peoples’ job statuses changing, I think it’s worthwhile to raise this in patient encounters,” Ms. Thomas said.
Overcoming conversational barriers
The first of three tables in the guide provides a list of “barriers to having a cost conversation” in the first column and “suggested solutions” in the second. For example, for the barrier, “You have insufficient time and/or knowledge about cost,” the suggestion is, “request and share available faculty and resources, including benefits coordinators, social workers, and community-based organizations. Work with the pharmacists and other members of the diabetes care team to identify resources that lower cost of medications.”
And for another barrier, “patients are often embarrassed or ashamed to initiate discussions of affordability,” the suggested solution is: “Normalize the issue of cost of care barriers for patients.”

Gut microbiome species predict type 2 diabetes
according to results from a 15-year follow-up study of more than 5,000 people in Finland.
“We are not aware of previous long-term prospective studies of the associations between type 2 diabetes and the gut microbiome similar to the current study,” stated the authors of the study, published online Jan. 31, 2022, in Diabetes Care.
Though requiring further validation, the results “build on and extend previous mainly cross-sectional evidence and further support links between dietary habits, metabolic diseases, and type 2 diabetes that are modulated by the gut microbiome,” the authors wrote.
The findings are from a prospective study of data on fecal samples from 5,572 people in Finland in 2002 in the FINRISK 2002 population cohort. In 2017, the samples were sent for sequencing as follow-up.
Of note, the study excluded people with prevalent diabetes at baseline, including those being treated with antidiabetic drugs such as metformin.
Four species, two clusters associated with type 2 diabetes development
Over a median follow-up of 15.8 years, 432 (7.8%) participants went on to have a diagnosis of type 2 diabetes, and the presence of four species and two clusters at baseline were significantly associated with the development of type 2 diabetes.
The four species include Clostridium citroniae (hazard ratio, 1.21; unadjusted P = .02), C. bolteae (HR, 1.20; unadjusted P = .01), Tyzzerella nexilis (HR, 1.17; unadjusted P = .03), and Ruminococcus gnavus (HR, 1.17; P = .04).
And the two positively associated clusters mostly consisted of the same species (both HR, 1.18).
Importantly, the associations were nearly the same among participants in eastern and western Finland, which are known for having unique genetic as well as lifestyle differences that impact morbidity and mortality.
“Three of these taxa could be clustered together by proportional abundance in both geographic areas, and combined abundance of the four taxa was also predictive of incident type 2 diabetes,” the authors wrote.
They noted that the identified species have been previously associated with type 2 diabetes and appear to be linked in some ways to the quality of diet and with other metabolic diseases, such as fatty liver disease.
C. citroniae, for instance, has been associated with trimethylamine N-oxide (TMAO), a compound likely linked to the intake of red meat, and the authors noted that a direct association between red meat intake and type 2 diabetes risk has been known for more than 15 years.
TMAO has also been associated with adipose tissue inflammation and impeded hepatic insulin signaling, which are all involved in increased insulin resistance, high blood glucose levels, and type 2 diabetes, the authors explained.
R. gnavus has been previously associated with obesity in humans and animals. And the bacterial species is also “potentially related to glucose metabolism regulation and linked to increases in inflammatory cytokines, both of which are related to type 2 diabetes pathophysiology,” the authors reported.
Stepping stone toward improved prediction
Coauthor Teemu J. Niiranen, MD, PhD, of the division of medicine, Turku (Finland) University Hospital, noted that, while prior studies have linked type 2 diabetes with distinctive characteristics of gut microbiome composition, most studies have not included prospective data, and long-term studies have been lacking.
Furthermore, many of the studies could have been confounded by the use of antidiabetic drugs that could influence gut microbiome composition, including metformin, which was excluded in the current study.
“We avoid several of the biases related to cross-sectional studies, such as the confounding effects of diabetes medications,” Dr. Niiranen said in an interview.
“We also know the temporal sequence of the exposure and the outcome, and that the changes in the gut microbiome preceded the development of diabetes,” he said. “All in all, a cohort study like this provides a much greater level of evidence than cross-sectional studies.”
Dr. Niiranen noted, however, that “although we demonstrate that certain gut microbiome changes are associated with greater risk of future diabetes, we are still quite far from clinical use.”
In addition to needing to replicate the results in other ethnic groups and locations, “we would need to find optimal clinical cutoffs for clinical decision-making and demonstrate the amount increase in predictive ability, compared with conventional diabetes risk factors,” he said.
The study nevertheless “serves as a stepping stone toward the goal of improved prediction and the development of effective treatments for type 2 diabetes through modification of the gut microbiome,” the authors wrote.
Other research has shed light on gut bacteria that appear to be linked to the prevention rather than the development of diabetes, identifying species that help produce butyrate, a short-chain fatty acid that may in fact provide protection against type 2 diabetes.
And additional research does suggest potential clinical implications. Efforts to improve insulin sensitivity via the gut through fecal microbial transplantation are also making headway, with an oral capsule formulation showing benefit among patients with severe obesity.
The research was funded in part by grants from the Finnish Cultural Foundation, the Finnish Foundation for Cardiovascular Research, the Emil Aaltonen Foundation, the Finnish Medical Foundation, the Sigrid Jusélius Foundation, and the Academy of Finland.

FROM DIABETES CARE
Past spontaneous abortion raises risk for gestational diabetes
Pregnant women with a history of spontaneous abortion had a significantly increased risk of gestational diabetes in subsequent pregnancies, based on data from more than 100,000 women.
Gestational diabetes is associated not only with adverse perinatal outcomes, but also with an increased risk of long-term cardiovascular and metabolic health issues in mothers and children, wrote Yan Zhao, PhD, of Tongji University, Shanghai, and colleagues.
Previous studies also have shown that spontaneous abortion (SAB) is associated with later maternal risk of cardiovascular disease and venous thromboembolism, the researchers said. The same mechanisms might contribute to the development of gestational diabetes, but the association between abortion history and gestational diabetes risk in subsequent pregnancies remains unclear, they added.
In a study published in JAMA Network Open, the researchers identified 102,259 pregnant women seen for routine prenatal care at a single hospital in Shanghai between January 2014 and December 2019. The mean age of the women was 29.8 years.
During the study period, 14,579 women experienced SAB (14.3%), 17,935 experienced induced abortion (17.5%), and 4,017 experienced both (11.9%).
In all, 12,153 cases of gestational diabetes were identified, for a prevalence of 11.9%. The relative risk of gestational diabetes was 1.25 for women who experienced SAB and 1.15 for those who experienced both SAB and induced abortion, and the association between SAB and gestational diabetes increased in a number-dependent manner, the researchers said. The increase in relative risk for gestational diabetes in pregnant women with one SAB, two SABs, and three or more SABs was 18%, 41%, and 43%, compared to pregnant women with no SAB history.
However, no association appeared between a history of induced abortion and gestational diabetes, the researchers said. “To date, no study has reported the association of prior induced abortion with gestational diabetes,” they wrote.
The study findings were limited by several factors including the reliance on self-reports for history of SAB and therefore possible underreporting, the researchers noted. Other limitations included the lack of data on the timing of SABs; therefore, the time between SAB and gestational diabetes diagnosis could not be included in the analysis, they said. Unknown variables and the inclusion only of women from a single city in China might limit the generalizability of the results, they added.
More research is needed to understand the biological mechanisms behind the association between SAB and gestational diabetes, an association that has potential public health implications, they noted. However, the results suggest that “pregnant women with a history of SAB, especially those with a history of recurrent SAB, should attend more antenatal visits to monitor their blood glucose and implement early prevention and intervention,” such as healthful eating and regular exercise, they wrote.
Findings confirm, not surprise
The diagnosis of gestational diabetes in the current study “was made with a slightly different test than we typically use in the United States – a 1-hour nonfasting glucola followed by a confirmatory 3-hour fasting glucola,” Sarah W. Prager, MD, of the University of Washington, Seattle, said in an interview. The current study of both SAB and gestational diabetes is important because both conditions are very common and have been the focus of increased attention in the popular media and in scientific study, she said.
Dr. Prager said she was not surprised by the findings of a link between a history of gestational diabetes and a history of SAB, “but the association is likely that people at risk for gestational diabetes or who have undiagnosed diabetes/glucose intolerance are more likely to experience SAB,” she noted. “I would be surprised if the direction of the association is that SAB puts people at risk for gestational diabetes; more likely undiagnosed diabetes is a risk factor for SAB,” she added. “Perhaps we should be screening for glucose intolerance and other metabolic disorders more frequently in people who have especially recurrent SAB, as the more miscarriages someone had, the more likely they were in this study to be diagnosed with gestational diabetes;” or perhaps those with a history of SAB/recurrent SAB should be screened closer to 24 weeks’ than 28 weeks’ gestation to enable earlier intervention in those more likely to have gestational diabetes, Dr. Prager said.
The study was supported by the Key Program of the National Natural Science Foundation of China, the National Natural Science Foundation of China, the National Key Research and Development Program of China, the Shanghai Municipal Medical and Health Discipline Construction Projects, and the Shanghai Rising-Star Program. The researchers and Dr. Prager had no financial conflicts to disclose. Dr. Prager serves on the editorial advisory board of Ob.Gyn. News.

Unknown variables and the inclusion only of women from a single city in China might limit the generalizability of the results, they added.
More research is needed to understand the biological mechanisms behind the association between SAB and gestational diabetes, an association that has potential public health implications, they noted. However, the results suggest that “pregnant women with a history of SAB, especially those with a history of recurrent SAB, should attend more antenatal visits to monitor their blood glucose and implement early prevention and intervention,” such as healthful eating and regular exercise, they wrote.
Findings confirm, not surprise
The diagnosis of gestational diabetes in the current study “was made with a slightly different test than we typically use in the United States – a 1-hour nonfasting glucola followed by a confirmatory 3-hour fasting glucola,” Sarah W. Prager, MD, of the University of Washington, Seattle, said in an interview. The current study of both SAB and gestational diabetes is important because both conditions are very common and have been the focus of increased attention in the popular media and in scientific study, she said.
Dr. Prager said she was not surprised by the findings of a link between a history of gestational diabetes and a history of SAB, “but the association is likely that people at risk for gestational diabetes or who have undiagnosed diabetes/glucose intolerance are more likely to experience SAB,” she noted. “I would be surprised if the direction of the association is that SAB puts people at risk for gestational diabetes; more likely undiagnosed diabetes is a risk factor for SAB,” she added. “Perhaps we should be screening for glucose intolerance and other metabolic disorders more frequently in people who have especially recurrent SAB, as the more miscarriages someone had, the more likely they were in this study to be diagnosed with gestational diabetes;” or perhaps those with a history of SAB/recurrent SAB should be screened closer to 24 weeks’ than 28 weeks’ gestation to enable earlier intervention in those more likely to have gestational diabetes, Dr. Prager said.
The study was supported by the Key Program of the National Natural Science Foundation of China, the National Natural Science Foundation of China, the National Key Research and Development Program of China, the Shanghai Municipal Medical and Health Discipline Construction Projects, and the Shanghai Rising-Star Program. The researchers and Dr. Prager had no financial conflicts to disclose. Dr. Prager serves on the editorial advisory board of Ob.Gyn. News.
