Music’s charms may soothe heart failure’s effects
Music listening and singing each showed early, promising evidence for producing cardiovascular benefits, part of a burgeoning area of research that is exploring and documenting ways to effectively use music to improve health.
A study run at four centers in Italy randomized 159 patients with heart failure, primarily New York Heart Association class I or II disease, to either a daily regimen of at least 30 minutes spent listening to music daily or to a control group that received usual care with no music prescription. After 3 months, the 82 patients in the daily music-listening group had a statistically significant improvement in their Minnesota Living with Heart Failure Questionnaire scores, compared with 77 controls for the study’s primary outcome measure. The results also showed significant benefits, compared with placebo, for other, secondary efficacy measures including improvements in anxiety, depression, sleep quality, and cognition.
Although the results are considered preliminary, they drew significant attention when published in July 2020 (J Card Fail. 2020 Jul 1;26[7]:541-9), where it was accompanied by two editorials in the same issue as well as an editor’s statement. All these commentators as well as other experts interested in music as medicine gathered to further discuss the topic during a panel session at the virtual annual meeting of the Heart Failure Society of America.
Music as a calming influence
The source of the primary benefits seen in this Italian study likely involved “emotional, psychological, and relaxation,” suggested Jerome L. Fleg, MD, program officer for clinical cardiovascular disease at the National Heart, Lung, and Blood Institute in Bethesda, Md. Researchers had used calming potential as a major criterion when selecting the 80 classical pieces that the heart failure patients in the intervention arm of the study could shuffle on their play lists.
“The tempo/rhythm was set up in a range between 60 and 80 beats per minute, because this range mirrors the human heart rate and facilitates relaxation,” the investigators said in their published report. Unfortunately, noted Dr. Fleg, the study lacked physiologic and biomarker measurements that could have provided objective evidence of effects from music. And the study failed to include a control arm of patients instructed to spend 30 minutes a day resting and relaxing without instruction to listen to music, he noted.
Dr. Fleg had authored one of the July editorials, where he said “It is hoped that findings from these studies and others can expand the scientific evidence for music-based interventions and bring these therapies into clinical practice. The current study from Burrai et al. is a positive step in this direction for patients with heart failure.” (J Card Fail. 2020 Jul 1;26[7]: 550-1). What’s needed now, he added during the virtual session, are “more objective data” to better and more comprehensively document the benefits from a music-based intervention in patients with heart failure.
An add-on to standard care
The findings in heart failure patients follows a growing literature that’s shown music can generate a restful state by doing things like activating autonomic parasympathetic outflow while dampening sympathetic outflow. This produces moderation in mood and emotion as well as depressed heart rate, lowered blood pressure, and slowed respiration, commented Emmeline Edwards, PhD director of the division of extramural research of the National Center for Complementary and Integrative Health in Bethesda, Md. Music also seems able to stimulate higher-order brain regions that can result in reduced psychological stress, anxiety, and depression.
“It’s a promising protective intervention to add to standard care for cardiac patients,” Dr. Edwards said during the virtual session. “Music is part of the toolbox for managing symptoms and improving health and well-being.”
“Music is not a substitute for standard therapy, but could add to it,” declared Dr. Fleg.
The already-established intervention known as music therapy has identified music’s ability to modulate breathing as an important mediator of music’s effect.
“Breathing is one of the few physiological processes that can be voluntarily controlled making it a viable target for intervention,” noted opera soprano Renée Fleming and Sheri L. Robb, PhD, in the second editorial that accompanied the Italian heart failure report (J Card Fail. 2020 Jul 1;26[7]:552-4). The music-listening intervention “may have had more effect if they had used compositional features [of the music] to teach patients how to structure their breathing,” said Dr. Robb, a music therapist at Indiana University–Purdue University Indianapolis, during the virtual session.
Another variable to consider is the type of music. “What is the emotional response to the music, and how does that affect heart rate,” wondered Dr. Robb, a professor at the Indiana University School of Nursing in Indianapolis.
Music as exercise
The division that Dr. Edwards directs recently funded a pilot study that assessed the feasibility of using music to stimulate activity and improve breathing another way, by repurposing singing as a novel form of rehabilitative exercise.
The pilot study enrolled patients with coronary disease into a randomized study that tested whether a 14-minute session of supervised singing could produce acute improvement in vascular function, “a biomarker for the risk of future cardiovascular disease events,” explained Jacqueline P. Kulinski, MD, a preventive cardiologist at the Medical College of Wisconsin in Milwaukee. Dr. Kulinski did not report details of her yet-unpublished study, but said that her initial findings held promise for developing musical activities such as singing as a novel way to stimulate therapeutic physical activity in patients with heart disease.
“It’s exciting to see this signal” of benefit. “I envision music therapy as a part of cardiac rehabilitation, or an alternative for patients who can’t participate in traditional rehab,” Dr. Kulinski said during the virtual session. “I think of singing as a physical activity, as exercise, and using this exercise as medicine.”
Harmonizing with the NIH
“Singing is like swimming: You need to hold your breath,” agreed Ms. Fleming, who participated on the virtual panel and has spearheaded a collaboration between the National Institutes of Health and the Kennedy Center for the Performing Arts, the Sound Health Initiative, that’s coordinating research into the connections between music and health. Ms. Fleming helped launch the Sound Health Initiative in 2017 by coauthoring a JAMA article with the NIH director that spelled out the rationale and goals of the project (JAMA. 2017 Jun 27;317[24]:2470-1), and by launching a lecture tour on the topic in a presentation she calls Music and the Mind.
Ms. Fleming has given her talk in more than 30 locations worldwide, and she’s found that “audiences love” the combination of neuroscience and music that her talks cover, she said. Her lectures highlight that, in addition to cardiovascular disease, the potential for music therapy and related interventions has been shown in patients with disorders that include autism, psychosis, pain, Parkinson’s disease, Alzheimer’s disease, and epilepsy.
The research highlighted in the session “opens new doors to prevention and treatment strategies using music for patients with heart failure and cardiovascular disease,” summed up Biykem Bozkurt, MD, professor of medicine at the Baylor College of Medicine in Houston and president of the Heart Failure Society of America, who helped organize the virtual session.
Dr. Fleg, Dr. Edwards, Dr. Robb, Dr Kulinski, Ms. Fleming, and Dr. Bozkurt had no relevant financial disclosures.

Divergent COVID-19 mental health impacts seen in Spain and China
Spain and China used very different public health responses to the COVID-19 crisis, and that has had significant consequences in terms of the mental health as well as physical health of the two countries’ citizens, Roger Ho, MD, reported at the virtual congress of the European College of Neuropsychopharmacology.
Dr. Ho, a psychiatrist at the National University of Singapore, presented a first-of-its-kind cross-cultural comparative study of the impact of the COVID-19 pandemic in two epicenters on opposite sides of the world. A total of 1,539 participants drawn from the general populations in the two countries completed the online National University of Singapore COVID-19 Questionnaire. The survey was conducted in late February/early March in China and in mid-April in Spain, times of intense disease activity in the countries.
The questionnaire assesses knowledge and concerns about COVID, precautionary measures taken in the last 14 days, contact history, and physical symptoms related to COVID in the last 14 days. The pandemic’s psychological impact was evaluated using the Impact of Event Scale–Revised (IES-R). Participants also completed the Depression, Anxiety, and Stress-21 Scale (DASS-21).
Of note, the pandemic has taken a vastly greater physical toll in Spain than China. As of May 5, there were 83,000 confirmed cases of COVID-19 in China, with a population of 1.39 billion, compared with 248,000 in Spain, with a population of 46.9 million. The Spanish case rate of 5,500 per 1 million population was 100 times greater than China’s; the Spanish mortality rate of 585 per million was 185-fold greater.
Mental health findings
Spaniards experienced significantly higher levels of stress and depression as reflected in DASS-21 subscale scores of 14.22 and 8.65, respectively, compared with 7.86 and 6.38, in Chinese respondents. Spanish subjects also reported greater anxiety levels than the Chinese on the DASS-21 anxiety subscale, although not to a statistically significant extent. Yet, counterintuitively, given the DASS-21 results, the pandemic had a greater adverse psychological impact on the Chinese subjects as reflected in their significantly higher average IES-D score of 30.76 versus 27.64 in Spain. Dr. Ho offered a hypothesis as to why: The survey documented that many Chinese respondents felt socially stigmatized, and that their nation had been discriminated against by the rest of the world because the pandemic started in China.
Satisfaction with the public health response
Spanish respondents reported less confidence in their COVID-related medical services.
“This could be due to the rising number of infected health care workers in Spain. In contrast, the Chinese had more confidence in their medical services, probably because the government quickly deployed medical personnel and treated COVID-19 patients at rapidly built hospitals,” according to Dr. Ho.
Spain and other European countries shared four shortcomings in their pandemic response, he continued: lack of personal protective equipment for health care workers, delay in developing response strategies, a shortage of hospital beds, and inability to protect vulnerable elderly individuals from infection in nursing homes.
Experiencing cough, shortness of breath, myalgia, or other physical symptoms potentially associated with COVID-19 within the past 14 days was associated with worse depression, anxiety, and stress scores in both China and Spain. This underscores from a mental health standpoint the importance of rapid and accurate testing for the infection, Dr. Ho said.
Significantly more Spanish respondents felt there was too much unnecessary worry about COVID-19, suggesting a need for better health education regarding the pandemic.
Use of face masks
Consistent use of face masks regardless of the presence or absence of symptoms was far more common in the Chinese epicenter, where, unlike in Spain, this precautionary measure was associated with significantly lower IES-R and DASS-21 scores.
but for the Spanish, wearing a face mask was associated with higher IES-R scores,” Dr. Ho said. “We understand that it is difficult for Europeans to accept the need to use masks for healthy people because mask-wearing suggests vulnerability to sickness and concealment of identity. The Chinese have a collective culture. They believe they should wear a face mask to protect their health and that of other people.”
Dr. Ho reported no financial conflicts regarding his study, conducted with coinvestigators at Huaibei (China) Normal University and Complutense University of Madrid.

Time to screen for liver disease in type 2 diabetes?
With high rates of fatty liver disease known to occur among people with type 2 diabetes, is it time to introduce routine liver screening into daily diabetes practice? The answer depends on whom you ask, and then there are still some important caveats.
From the hepatologist’s perspective, there is no excuse not to consider liver surveillance now that noninvasive screening methods are available, suggested Michael Trauner, MD, of the Medical University of Vienna.
“From a practical standpoint, I think every type 2 diabetic over 50 years of age is at high risk,” and consequently should be screened at diagnosis, Dr. Trauner said during a debate at the virtual annual meeting of the European Association for the Study of Diabetes. “I would screen at diagnosis and then decide on recall depending on noninvasive fibrosis markers.”
“It’s a rising problem that we are facing these days,” observed Michael Roden, MD, chair and professor of internal medicine, endocrinology and metabolic diseases at Heinrich-Heine University in Düsseldorf, Germany, and who cochaired the session. Not only do people with type 2 diabetes have an increased risk for developing liver diseases, but also there’s a higher risk for those with fatty liver diseases developing type 2 diabetes.
A meta-analysis published in Gut in just last week illustrates just how big a problem this is – nonalcoholic fatty liver disease (NAFLD) “doubled the risk of type 2 diabetes,” said Dr Rosen, who is also the director of the division of endocrinology and diabetology at University Clinics Düsseldorf. That analysis was based on more than 500,000 people, almost 28,000 of whom had incident diabetes over a 5-year period.
Screening tools scarce
This makes liver screening in type 2 diabetes patients “a formidable challenge,” cautioned Gianluca Perseghin, MD, professor of endocrinology at the Monza (Italy) Polyclinic and the University of Milano-Bicocca in Milan.
“Hepatologists generally see only the most severe cases,” Dr. Perseghin said. Diabetologists and endocrinologists would be likely to see huge numbers of patients that could potentially be at risk for liver disease and following the recommendations set out in the joint European Association for the Study of the Liver/EASD/European Association for the Study of Obesity guidelines would result in a huge number of patients being identified and potentially needing referral, he argued.
“At this stage, we need to build friendly, reliable and cost-effective screening process to be applied in the health systems,” Dr. Perseghin suggested. He proposed that liver surveillance would need to be not only personalized on a patient level, but also at the infrastructure level. Measuring liver enzymes, for example, was going to be less accurate in picking up liver disease but blood tests were widely available, whereas imaging methods were not going to be something all diabetes clinics would have immediate access to.
“There are clearly a lot of provocative decisions still to be made,” acknowledged Philip Newsome, PhD, FRCPE, an honorary consultant hepatologist at the University of Birmingham (England) and who cochaired the debate.
“We need to demonstrate that looking for the presence of liver disease in this cohort changes their outcomes in a way that is cost effective,” Dr. Newsome, who is also the secretary general of EASL.
“Tests are evolving, but more importantly, treatments are evolving. So, the decision around cost effectiveness will clearly change,” he added.
NAFLD therapies unclar
“There are still a lot of questions,” Dr. Newsome said during a Novo-Nordisk–sponsored “Meet the Expert” session discussing EASL-EASD-EASO guidelines. “We don’t have any licensed therapies at the moment. But there’s been a huge amount of investment, looking at all sorts of different approaches.”
Dr. Newsome added: “We also don’t know how to monitor these patients. Most of the noninvasive are very useful for staging patients, but we don’t really understand how useful they are for monitoring changes in fibrosis.”
Diabetologist Hannele Yki-Järvinen, MD, PhD, of the University of Helsinki, gave her thoughts on the topic during the same session.
“We should add FIB-4 [Fibrosis-4 index] to the annual exam and ask the lab to calculate FIB-4 automatically,” Dr. Yki-Järvinen said. FIB-4is calculated using the patients age and the results of readily available blood tests that measure the AST/ALT ratio and the platelet count.

Dr. Perseghin has received honoraria and grant support from various pharmaceutical companies with an interest in diabetes care. Dr. Roden did not provide any disclosures.

REPORTING FROM EASD 2020
Dapagliflozin’s CKD performance sends heart failure messages
The DAPA-CKD trial results, which proved dapagliflozin’s efficacy for slowing chronic kidney disease progression in patients selected for signs of worsening renal function, also have important messages for cardiologists, especially heart failure physicians.
Those messages include findings that were “consistent” with the results of the earlier DAPA-HF trial, which tested the same sodium-glucose transporter 2 (SGLT2) inhibitor in patients selected for having heart failure with reduced ejection fraction (HFrEF). In addition, a specific action of dapagliflozin (Farxiga) on the patients in DAPA-CKD, which enrolled patients based on markers of chronic kidney disease (CKD), was prevention of first and recurrent heart failure hospitalizations, John J.V. McMurray, MD, said at the virtual annual scientific meeting of the Heart Failure Society of America, further highlighting the role that dapagliflozin has in reducing both heart failure and renal events.
What DAPA-CKD means for heart failure
The main findings from the DAPA-CKD trial, published in September in the New England Journal of Medicine, included as a secondary outcome the combined rate of death from cardiovascular causes or hospitalization for heart failure (HHF). Treatment with dapagliflozin linked with a significant 29% relative reduction in this endpoint, compared with placebo-treated patients. At the HFSA meeting, Dr. McMurray reported for the first time the specific HHF numbers, a prespecified secondary endpoint for the study.
Patients on dapagliflozin had 37 total HHF events (1.7%), including both first-time and subsequent hospitalizations, while patients in the placebo arm had a total of 71 HHF events (3.3%) during the study’s median 2.4 years of follow-up, an absolute reduction of 1.6% that translated into a relative risk reduction of 49%.
The HHF findings from DAPA-CKD importantly showed that SGLT2 inhibition in patients with signs of renal dysfunction “will not only slow progression of kidney disease but will also reduce the risk of developing heart failure, crucially in patients with or without type 2 diabetes,” explained Dr. McMurray in an interview. “Cardiologists often consult in the kidney wards and advise on management of patients with chronic kidney disease, even those without heart failure.”
The DAPA-CKD findings carry another important message for heart failure management regarding the minimum level of renal function a patient can have and still safely receive dapagliflozin or possibly another agent from the same SGLT2 inhibitor class. In DAPA-CKD, patients safely received dapagliflozin with an estimated glomerular filtration rate (eGFR) as low as 25 mL/min per 1.73 m2; 14% of enrolled patients had an eGFR of 25-29 mL/min per 1.73 m2.
“Typically, about 40%-50% of patients with heart failure have chronic kidney disease,” which makes this safety finding important to clinicians who care for heart failure patients, but it’s also important for any patient who might be a candidate for dapagliflozin or another drug from its class. “We had no strong evidence before this trial that SGLT2 inhibition could reduce hard renal endpoints,” specifically need for chronic dialysis, renal transplant, or renal death, “in patients with or without diabetes,” Dr. McMurray said.
DAPA-CKD grows the pool of eligible heart failure patients
A further consequence of the DAPA-CKD findings is that when, as expected, regulatory bodies give dapagliflozin an indication for treating the types of CKD patients enrolled in the trial, it will functionally expand this treatment to an even larger swath of heart failure patients who currently don’t qualify for this treatment, specifically patients with CKD who also have heart failure with preserved ejection fraction (HFpEF). On Oct. 2, 2020, the Food and Drug Administration fast-tracked dapagliflozin for the CKD indication by granting it Breakthrough Therapy Designation based on the DAPA-CKD results.
Results first reported in 2019 from the DAPA-HF trial led to dapagliflozin receiving a labeled indication for treating HFrEF, the types of heart failure patients enrolled in the trial. Direct evidence on the efficacy of SGLT2 inhibitors for patients with HFpEF will not be available until results from a few trials now in progress become available during the next 12 months.
In the meantime, nearly half of patients with HFpEF also have CKD, noted Dr. McMurray, and another large portion of HFpEF patients have type 2 diabetes and hence qualify for SGLT2 inhibitor treatment that way. “Obviously, we would like to know specifically about heart failure outcomes in patients with HFpEF” on SGLT2 inhibitor treatment, he acknowledged. But the recent approval of dapagliflozin for patients with HFrEF and the likely indication coming soon for treating CKD means that the number of patients with heart failure who are not eligible for SGLT2 inhibitor treatment is dwindling down to some extent.
New DAPA-HF results show no drug, device interactions
In a separate session at the HFSA virtual meeting, Dr. McMurray and several collaborators on the DAPA-HF trial presented results from some new analyses. Dr. McMurray looked at the impact of dapagliflozin treatment on the primary endpoint when patients were stratified by the diuretic dosage they received at study entry. The results showed that “the benefits from dapagliflozin were irrespective of the use of background diuretic therapy or the diuretic dose,” he reported. Study findings also showed that roughly three-quarters of patients in the study had no change in their diuretic dosage during the course of the trial, that the fraction of patients who had an increase in their dosage was about the same as those whose diuretic dosage decreased, and that this pattern was similar in both the patients on dapagliflozin and in those randomized to placebo.
Another set of new analyses from DAPA-HF looked at the impact on dapagliflozin efficacy of background medical and device therapies for heart failure, as well as background diabetes therapies. The findings showed no signal of an interaction with background therapies. “The effects of dapagliflozin are incremental and complimentary to conventional therapies for HFrEF,” concluded Lars Kober, MD, a professor and heart failure physician at Copenhagen University Hospital.
DAPA-CKD was funded by AstraZeneca, the company that markets dapagliflozin (Farxiga). Dr. McMurray’s employer, Glasgow University, has received payments from AstraZeneca and several other companies to compensate for his time overseeing various clinical trials. Dr. Kober has received honoraria for speaking on behalf of several companies including AstraZeneca.

Tailoring cosmetic procedures for skin of color patients minimize risks
Based on the fact that hyperpigmentation and other adverse events associated with cosmetic dermatologic procedures are relevant to skin type, not racial identification, individualized strategies to minimize the risk of potential adverse events are always appropriate, according to an expert speaking at the virtual Skin of Color Update 2020.
There are many highly effective interventions that employ lasers, chemical peels, and topical agents to achieve excellent cosmetic results in darker skin, but results are highly dependent on first understanding the relative risks and treatment goals, Cheryl Burgess, MD, president and founder of the Center for Dermatology and Dermatologic Surgery, Washington, D.C., said at the meeting.
She stressed the importance of educating patients that “all cosmetic procedures are not for skin of color.” Her approach is to engage patients on what they are trying to accomplish and then seeking a solution that tailors treatment to skin type based on the Fitzpatrick scale, the Roberts Hyperpigmentation Scale, or other guidance.
“There are so many different methods that we can use, and these are not necessarily the ones that patients have read about in a magazine,” Dr. Burgess said.
Intense pulsed laser (IPL) for hair removal is an example. This technique is not appropriate in patients with Fitzpatrick skin type IV or higher, according to Dr. Burgess, who presented a case example of a bad outcome. In this case, a patient came to her for treatment after exposure to IPL resulted in first- and second-degree burns complicated by extensive hypopigmentation.
Ultimately, the solution in this case involved more laser therapy, but this time a strategy was selected appropriate to skin of color.
“It is hard to suggest to a patient that we are going to use a laser device” when the problem was caused by a laser, Dr. Burgess observed, but properly selected lasers are effective and should be considered in patients with dark skin.
In this case, triple cream containing 6% hydroquinone was the first step towards resolving the hyperpigmentation. Jessner’s peel was also applied to increase penetration.
Laser treatment using two different types of devices was also employed: A 1,927-nm thulium-fractionated erbium glass laser and a 650-microsecond 1,064-nm Nd:YAG laser. The excellent resolution of the hyperpigmentation demonstrates that lasers are effective in dark skin when used appropriately, she noted.
Dr. Burgess emphasized that tailored therapy is not just relevant to Black patients. She cited data indicating that the proportion of multiracial individuals in the United States is increasing, and when tailoring cosmetic procedures, she recommended considering skin characteristics, not just skin color.
Relative to white skin, pigmented skin typically has greater elasticity, greater amounts of collagen, and greater oil content. Importantly, darker skin has a greater propensity to darkening as a result of injury, she said.
In a review of the hyperpigmentation process that follows injury or other insults, Dr. Burgess reported that only three occur inside the melanocyte. There are now topically applied agents to intervene at many of these steps, including hydroquinone to reduce up-regulation of tyrosinase enzymes, and cysteamine to inhibit conversion of DOPA to dopaquinone. All of these, often used in combination, offer potential benefit in skin of color.
However, “you must understand skin of color,” Dr. Burgess emphasized. For example, most hyaluronic acid dermal fillers can be considered in patients with Fitzpatrick skin types IV or higher with low risks for hypo- or hyperpigmentation, scarring, or keloid formation, but technique is important.
“There is more postinflammatory hyperpigmentation with serial or multiple puncture injection techniques” in dark skin relative to lighter skin, according to Dr. Burgess. She recommended reducing this risk with relatively slow injection times.
When in doubt about the result with any cosmetic procedure, test spots are a reasonable strategy, Dr. Burgess said. When there is concern about risk for adverse events, she recommended using low doses and longer intervals between treatments than might otherwise be considered. Patients should participate in understanding the rationale for selecting one approach over another.
It helps for patients to know that “the desired outcome may take many more sessions than what they read about in that we might have to consider conservative measures in order to ensure that we accomplish the cosmetic effect than they want,” she said.
It is critical that clinicians who perform laser or other cosmetic procedures on darker skin be aware of these precautions, agreed Eliot F. Battle Jr., MD, CEO and cofounder of Cultura Dermatology and Laser Center, Washington, D.C. “Over the past 20 years, we have improved lasers that can safely and effectively treat patients with skin of color, but we still have a way to go,” he said at the meeting. Darker skin behaves differently in response to this energy.
“The pigment in the skin of patients of color competes for the laser light, which can cause heat-related side effects, like blistering and pigmentary changes. Skin of color also has an increased incidence of scarring and unwanted pigmentary changes from laser treatments that create irritation and inflammation,” he explained.
It is important to be aware of these differences, but practitioners also “need to treat conservatively to minimize these unwanted side effects,” Dr. Battle said.
Dr. Burgess reported financial relationships with Allergan, Merz Aesthetics, Revance Therapeutics, and Galderma. Dr. Battle had no commercial disclosures.
Based on the fact that hyperpigmentation and other adverse events associated with cosmetic dermatologic procedures are relevant to skin type, not racial identification, individualized strategies to minimize the risk of potential adverse events are always appropriate, according to an expert speaking at the virtual Skin of Color Update 2020.
There are many highly effective interventions that employ lasers, chemical peels, and topical agents to achieve excellent cosmetic results in darker skin, but results are highly dependent on first understanding the relative risks and treatment goals, Cheryl Burgess, MD, president and founder of the Center for Dermatology and Dermatologic Surgery, Washington, D.C., said at the meeting.
She stressed the importance of educating patients that “all cosmetic procedures are not for skin of color.” Her approach is to engage patients on what they are trying to accomplish and then seeking a solution that tailors treatment to skin type based on the Fitzpatrick scale, the Roberts Hyperpigmentation Scale, or other guidance.

High-dose TRT: A new standard of care for LS-SCLC?
In a phase 2 trial, the 2-year overall survival rate was 51.3% when twice-daily TRT was given at a dose of 45 Gy in 30 fractions and 75% when it was given at a dose of 60 Gy in 40 fractions in patients with LS-SCLC. The two treatment arms had similar safety and quality of life outcomes.
The higher dose “did not add toxicity,” a significant concern with higher radiation doses, said Bjorn Gronberg, MD, PhD, of the Norwegian University of Science and Technology in Trondheim, when presenting this study at the European Society for Medical Oncology Virtual Congress 2020.
However, the discussant for this study pointed out several limitations of the trial and concluded that the 45 Gy dose should remain the standard of care.
Dr. Gonberg explained that concurrent platinum/etoposide (PE) chemotherapy and TRT is the standard treatment for LS-SCLC, and the most recommended schedule for TRT is twice daily at 45 Gy in 30 fractions. He noted, however, that “there’s clearly a need for better treatment” because less than 30% of patients are cured.
“We hypothesized that increasing the dose of radiotherapy might improve survival,” he said.
Study details
Dr. Gonberg and colleagues conducted a phase 2 trial of patients with stage I-III SCLC confined to one hemithorax plus regional lymph nodes. The trial enrolled 176 patients and randomized 170 of them.
The patients received four courses of PE 3 weeks apart. For TRT, 81 patients were randomized to 45 Gy in 30 fractions, and 89 patients were randomized to 60 Gy in 40 fractions, with 10 fractions per week starting with the second PE course.
All patients who responded to chemoradiotherapy were offered prophylactic cranial irradiation at 25 Gy in 10 fractions or 30 Gy in 15 fractions.
Baseline characteristics were well balanced between the treatment arms. The median age was 65 years in both arms, and most patients were women (60.5% in the 45 Gy arm and 56% in the 60 Gy arm).
The mean number of chemotherapy courses was 3.8 in each arm, about 85% of patients received prophylactic cranial radiation, and roughly half received second-line chemotherapy. Overall, 73 patients completed TRT in the 45 Gy arm, and 81 completed TRT in the 60 Gy arm.
Efficacy
There was no significant difference in overall response rate between the treatment arms. It was 81.6% in the 45 Gy arm and 82.1% in the 60 Gy arm (P = .81).
Similarly, there was no significant difference in progression-free survival. The median progression-free survival was 11.1 months in the lower-dose arm and 18.7 months in the higher-dose arm (P = .22).
Still, there was a significant difference in overall survival between the arms. The 2-year overall survival rate was 51.3% in the lower-dose arm and 75% in the higher-dose arm (P = .002). The median overall survival was 24 months and 37.2 months, respectively (P = .034).
Discussant Corinne Faivre-Finn, MD, PhD, of the University of Manchester (England), cautioned that the lower-dose arm appeared to underperform, compared with prior research.
Additionally, “the survival curves separate at about 9 months, [with a] significant difference at 2 years, but the survival curves are coming back together at around 5 years, and that shows that there is a small difference in terms of long-term cure,” she said.
Safety
There were no significant differences in toxicity between the treatment arms.
Dr. Gronberg noted that esophagitis is considered the main dose-limiting toxicity with TRT, but there was no difference in incidence between the two arms (P = .916). Grade 3 esophagitis occurred in 18.4% of patients in the lower-dose arm and 19% of those in the higher-dose arm. There was no grade 4 esophagitis.
Rates of grade 3 and 4 neutropenic infections were higher in the lower-dose arm than in the higher-dose arm, but the difference was not statistically significant (P = .08).
There were also no significant differences in quality of life surveys that patients filled out periodically from baseline until week 52.
“Not so surprisingly,” Dr. Gronberg said, dysphagia was more common at the end of TRT. However, patients had recovered to baseline levels at week 22.
“There’s no difference in the maximum dysphagia reported between the treatment arms, but ... patients in the high-dose arm needed longer time to recover from dysphagia,” Dr. Gronberg said.
Scores for dyspnea, physical function, and global quality of life were similar between the treatment arms.
The similar toxicity between the arms “is quite puzzling,” Dr. Faivre-Finn said, given the 33% increase in radiation dose in the experimental arm. She said this “probably points out an imbalance in some of the factors” between the groups, including tumor volume and doses to organs at risk, which were not reported.
“There are some important missing data, in terms of interpretation of results,” she said.
Given the limitations, and the fact that the study population was relatively small, Dr. Faivre-Finn said “the results cannot be considered definitive and practice changing,” pending additional study.
“So my final conclusion is that twice-a-day radiotherapy at a dose of 45 Gy remains the standard of care, as recommended in the recently published ASTRO [American Society for Radiation Oncology] guidelines,” Dr. Faivre-Finn said.
The study was funded by the Norwegian Cancer Society, the Nordic Cancer Union, and the Norwegian University of Science and Technology. Dr. Gronberg disclosed relationships with Pfizer, Roche, Eli Lilly, and other companies. Dr. Faivre-Finn disclosed relationships with AstraZeneca, Merck, Pfizer, Elekta, and Boehringer Ingelheim.

New treatment options show promise for centrifugal cicatricial alopecia
according to a review of current strategies for this challenging disease, delivered at the virtual Skin of Color Update 2020.
Two case reports of favorable results with topical metformin were published earlier this year. A subsequent case in which metformin provided a major improvement in quality of life has provided further encouragement, according to Crystal Aguh, MD, director of the ethnic skin program at Johns Hopkins University, Baltimore.
In the subsequent case, there was complete scalp coverage, allowing the patient to no longer use a wig, which is “tough to achieve in patients with advanced disease,” Dr. Aguh said.
In the two published cases, 10% metformin compounded in Lipoderm (PCCA) produced notable hair growth within 6 months. Dr. Aguh said that the case studies were prompted by experimental evidence associating metformin with an antifibrotic effect.
This finding is potentially important. Most current treatments for CCCA are based on anti-inflammatory activity, according to Dr. Aguh, but fibrosis is strongly implicated in the pathogenesis of CCCA. Of several lines of evidence, one is the association between CCCA and other fibrosing conditions.
For example, women with CCCA “are several times more likely to have uterine fibroids than women without CCCA,” said Dr. Aguh, citing a study that she published in 2018. She suggested that there is an urgent need for new treatment options because of the “often-disappointing” responses to current standard therapies.
In the CCCA cases treated so far, topical metformin has been well tolerated, which is attributed to the low level of systemic absorption. No nausea or other gastrointestinal side effects common to oral metformin have been so far observed in Dr. Aguh’s cases.
“Some patients experience scalp dryness or irritation,” she said, but added that a light coating of emollient typically relieves this complaint.
Despite the promising results, topical metformin “is not a silver bullet,” Dr. Aguh cautioned. She estimated that only 10%-15% of patients respond, but this treatment can be considered “as an adjunctive option to avoid another round of intralesional steroids.”
Platelet-rich plasma (PRP) is another option that has demonstrated promise in a published case report for which Dr. Aguh served as a coauthor. In this series of two patients, only one had CCCA. The other had lichen planopilaris, but both patients experienced hair regrowth after failing standard therapies.
When treating alopecia with PRP, Dr. Aguh typically offers three or four sessions spaced 4 weeks apart. She does not start other treatments at the same time, but she does not discontinue topical treatments that patients are already taking, including topical minoxidil.
Again, like topical metformin, PRP is reasonably considered in patients who have failed standard therapies, according to Dr. Aguh. She cautioned that responses are not permanent. Patients who respond typically require retreatment a year or more later, but good responses have been seen after retreatment.
Appropriate hair care can help. Dr. Aguh recounted a case in which a patient with presumed CCCA was referred after failing intralesional triamcinolone injections. Ultimately, the patient was diagnosed with acquired trichorrhexis nodosa, but the large clinical improvements gained from better hair care practices, including avoidance of chemical relaxants and thermal styling, are relevant to CCCA, as well as other conditions resulting in hair loss.
In a book written by Dr. Aguh, titled “90 Days to Beautiful Hair,” strategies for better hair care practices include advice to reduce tension on hair follicles.
The role of increased traction is an issue in CCCA, agreed Amy McMichael, MD, chair of the department of dermatology, Wake Forest University, Winston-Salem, N.C. Although she provided data at the meeting suggesting that CCCA is a fibrosing disease linked to genetic susceptibility, she said there is also a “strong association” between the severity of CCCA and extensions, hair weaving, and other tension-associated hairstyles.
While there is an urgent need to develop therapies that address the underlying pathophysiology of CCCA, she concurred that patients with this or other conditions associated with hair loss, such as seborrheic dermatitis or frontal fibrosing alopecia, should not ignore appropriate hair care.
Dr. Aguh has financial relationships with LEO Pharma and UCB Pharma. Dr. McMichael’s disclosures included serving as an investigator and/or consultant for companies that included Allergan, Procter & Gamble, Nutrafol, Johnson & Johnson, and Aclaris.
according to a review of current strategies for this challenging disease, delivered at the virtual Skin of Color Update 2020.
Two case reports of favorable results with topical metformin were published earlier this year. A subsequent case in which metformin provided a major improvement in quality of life has provided further encouragement, according to Crystal Aguh, MD, director of the ethnic skin program at Johns Hopkins University, Baltimore.
In the subsequent case, there was complete scalp coverage, allowing the patient to no longer use a wig, which is “tough to achieve in patients with advanced disease,” Dr. Aguh said.
In the two published cases, 10% metformin compounded in Lipoderm (PCCA) produced notable hair growth within 6 months. Dr. Aguh said that the case studies were prompted by experimental evidence associating metformin with an antifibrotic effect.
This finding is potentially important. Most current treatments for CCCA are based on anti-inflammatory activity, according to Dr. Aguh, but fibrosis is strongly implicated in the pathogenesis of CCCA. Of several lines of evidence, one is the association between CCCA and other fibrosing conditions.
For example, women with CCCA “are several times more likely to have uterine fibroids than women without CCCA,” said Dr. Aguh, citing a study that she published in 2018. She suggested that there is an urgent need for new treatment options because of the “often-disappointing” responses to current standard therapies.
In the CCCA cases treated so far, topical metformin has been well tolerated, which is attributed to the low level of systemic absorption. No nausea or other gastrointestinal side effects common to oral metformin have been so far observed in Dr. Aguh’s cases.
“Some patients experience scalp dryness or irritation,” she said, but added that a light coating of emollient typically relieves this complaint.
Despite the promising results, topical metformin “is not a silver bullet,” Dr. Aguh cautioned. She estimated that only 10%-15% of patients respond, but this treatment can be considered “as an adjunctive option to avoid another round of intralesional steroids.”

Apatinib plus gefitinib: Better PFS but more toxicity
ACTIVE is the first phase 3 trial of an oral vascular epidermal growth factor receptor–2 (VEGFR2) tyrosine kinase inhibitor (TKI) added to an EGFR-TKI as first-line therapy in this population, according to Li Zhang, MD, of Sun Yat-sen University Cancer Center in Guangzhou, China.
Dr. Zhang presented results from ACTIVE at the European Society for Medical Oncology Virtual Congress 2020.
“This dual oral regimen will provide more convenient treatment for patients who require long-term administration,” Dr. Zhang said. He added that apatinib plus gefitinib “is expected to become a new first-line treatment option for EGFR-mutant NSCLC.”
A discussant for the ACTIVE study was less optimistic, however, noting that the regimen proved tough to tolerate for some patients, and the PFS benefit may not translate to overall survival.
Study rationale and details
Sensitizing EGFR mutations occur in about 10% of White patients and up to 50% of Asian patients, Dr. Zhang noted. Unfortunately, most patients progress after first-line treatment with EGFR-TKIs because of acquired resistance.
Blocking VEGF receptor pathways has been shown to enhance EGFR-TKIs in EGFR-mutated NSCLC, and pilot study results have shown apatinib – an oral VEGFR2–TKI – to be safe and well-tolerated with promising efficacy in combination with gefitinib, Dr. Zhang added.
To expand upon those results, he and his colleagues tested apatinib with gefitinib in the phase 3, double-blind, placebo-controlled ACTIVE trial (CTONG1706).
The trial included 313 patients (median age, 58.5 years) with locally advanced, metastatic, or recurrent nonsquamous NSCLC. All were chemotherapy-naive and EGFR mutation-positive (exon 19 deletion or exon 21 L858R).
Patients were randomized 1:1 to first-line apatinib at 500 mg daily plus gefitinib at 250 mg daily (n = 157) or placebo plus gefitinib at 250 mg daily (n = 156) until progressive disease or unacceptable toxicity.
Efficacy and safety
The primary endpoint was PFS by independent review. The median follow-up was 15.8 months.
The median PFS was 13.7 months in the apatinib group and 10.2 months in the placebo group (hazard ratio, 0.71; P = .0189).
Objective response rates were similar for both groups – 77.1% with apatinib and 73.7% with placebo. However, depth of response ≥30% and depth of response ≥50% both favored the apatinib arm – 89.2% versus 79.5% for ≥ 30% (P = .0209) and 64.3% versus 52.6% for ≥50% (P = .0238).
In addition, the median duration of response was longer for the apatinib group – 12.9 months versus 9.3 months (HR, 0.64; P = .005).
Exploratory biomarker analyses showed the benefit of apatinib was more common in patients with TP53 exon 8 mutations.
The rate of grade 3 or higher treatment-emergent adverse events was 84.1% in the apatinib arm and 37.7% in the placebo arm. Diarrhea (73.2%) and hypertension (68.2%) were the most common treatment-emergent adverse events in the apatinib group.
Dose interruptions were more common in the apatinib group (59.5% vs. 22.7%) as were dose reductions (48.4% vs. 4.5%). However, treatment discontinuations attributable to treatment-emergent adverse events were few in both arms (5.1% in the apatinib arm and 3.2% in the placebo arm).
Cause for hesitation
“VEGFR-TKIs have not yet found a solid home in lung cancer,” said study discussant Lecia V. Sequist, MD, of Massachusetts General Hospital in Boston.
Listing 10 VEGFR-TKIs, Dr. Sequist noted: “None of them have changed practice.”
She added that, while an all-oral regimen is appealing, the benefit of adding apatinib to gefitinib was modest, and the regimen was “fairly difficult” to tolerate. “The PFS with apatinib plus gefitinib is well below what we see with other EGFR/VEGF first-line studies,” she said.
Dr. Sequist also observed that most studies have shown a PFS benefit but no overall survival benefit. “That, in combination with the toxicity, makes me a little hesitant about this regimen. The role of VEGF remains unclear in EGFR mutation–positive lung cancer in 2020,” she concluded.
The ACTIVE study was funded by Jiangsu HengRui Medicine, the Chinese Thoracic Oncology Group, and grants from Sun Yat-sen University and the National Key R&D Program of China. Dr. Zhang disclosed relationships with AstraZeneca, Bristol-Myers Squibb, Eli Lilly, Pfizer, and Roche. Dr. Sequist disclosed relationships with AstraZeneca, Bristol-Myers Squibb, Blueprint Medicines, and many other companies.

Screening algorithm safely selects patients for OSA treatment before bariatric surgery
A novel algorithm for selecting patients who require treatment for obstructive sleep apnea (OSA) before undergoing bariatric surgery proved safe in a prospective cohort study of 1,103 patients.
Screening for OSA is recommended before bariatric surgery. OSA has been associated in several meta-analyses with increased risk for postoperative complications – not limited to bariatric surgery – and some studies have suggested that this increased risk may be limited to severe OSA, said Frédéric Series, MD, of Université Laval, Quebec City, at the virtual annual meeting of the Associated Sleep Societies.
The preoperative screening algorithm, which utilizes the results of nocturnal home oximetry and morning capillary gas measurements, effectively stratified patients for the risk of postoperative adverse events and “safely selected patients who don’t need [continuous positive airway pressure] before bariatric surgery,” he said. “The risk of postoperative adverse events following bariatric surgery was not increased in untreated OSA patients with low or moderate risk of severe OSA and hypoventilation.”
The study also demonstrated, he said, that patients with severe OSA with or without hypoventilation, even when correctly treated, remain at higher risk for complications.
The algorithm utilizes an oxygen desaturation index (ODI) corresponding to 3% drops in SaO2 and the percent of the total recording time with an SaO2 below 90%, as well as capillary gas measurements (PCO2). Treatment was initiated for those with severe OSA (ODI ≥ 25/hr, < 10% of recording time with a SaO2 below 90%) or OSA with hypoventilation (PCO2 ≥ 45).
“When the ODI was less than 25 per hour, and when the total recording time spent below 90% SaO2 was less than 10%, with PCO2 < 45 mmHg, we expected no need for CPAP treatment,” Dr. Series said. For analysis, the investigators considered part of the untreated group – those with an ODI < 10/hr (no or mild OSA) – as a control group.
Treated patients underwent CPAP/BiPAP for a mean duration of 1.5 months. Good treatment compliance was mandatory for surgery, and treatment was continued immediately after extubation, in the recovery room, in nearly all patients, Dr. Series reported.
The analysis covered 1,103 patients: 447 controls (40.8%), 358 untreated (32.7%), 289 treated for OSA (26.4%) and 9 (0.8%) treated for OSA + hypoventilation. Patients with OSA, particularly those with severe OSA and those with hypoventilation, were older and heavier and significantly more likely to have hypertension and diabetes than controls.
There were no differences between the four groups in 10-day reoperation or 30-day readmission occurrence, and postoperative complications were “particularly infrequent in the control and OSA-untreated groups, with no differences between these two groups,” Dr. Series said.
Cardiac arrhythmia (mainly atrial fibrillation) occurred more frequently in the OSA-treated group (2.4%) and the OSA/hypoventilation patients (11%) than in the other groups (0.5%-0.6%).
Respiratory failure occurred in about one-third of patients with hypoventilation, and admission to the ICU was “dramatically higher” in patients with hypoventilation (67%), because of respiratory failure, arrhythmia, or other unstable medical conditions, Dr. Series said.
There were no differences between the groups in the duration of surgery or the amount of anesthetic used, but the length of stay in the recovery room was significantly longer in the OSA-treated and hypoventilation groups. The length of hospital stay was also longer in these groups. Sleeve gastrectomy was the most frequent bariatric surgical procedure across all groups, including 100% of patients with hypoventilation, he noted.
Asked to comment on the study, Octavian C. Ioachimescu, MD, PhD, of Emory University in Atlanta and the Atlanta Veterans Affairs Medical Center in Decatur, said the algorithm “clearly deserves further validation in other clinical-based cohorts and longer-term outcome assessment.”
Dr. Series reported that he has no relevant disclosures. Dr. Ioachimescu also said he has no relevant disclosures.

The preoperative screening algorithm, which utilizes the results of nocturnal home oximetry and morning capillary gas measurements, effectively stratified patients for the risk of postoperative adverse events and “safely selected patients who don’t need [continuous positive airway pressure] before bariatric surgery,” he said. “The risk of postoperative adverse events following bariatric surgery was not increased in untreated OSA patients with low or moderate risk of severe OSA and hypoventilation.”
The study also demonstrated, he said, that patients with severe OSA with or without hypoventilation, even when correctly treated, remain at higher risk for complications.
The algorithm utilizes an oxygen desaturation index (ODI) corresponding to 3% drops in SaO2 and the percent of the total recording time with an SaO2 below 90%, as well as capillary gas measurements (PCO2). Treatment was initiated for those with severe OSA (ODI ≥ 25/hr, < 10% of recording time with a SaO2 below 90%) or OSA with hypoventilation (PCO2 ≥ 45).
“When the ODI was less than 25 per hour, and when the total recording time spent below 90% SaO2 was less than 10%, with PCO2 < 45 mmHg, we expected no need for CPAP treatment,” Dr. Series said. For analysis, the investigators considered part of the untreated group – those with an ODI < 10/hr (no or mild OSA) – as a control group.
Treated patients underwent CPAP/BiPAP for a mean duration of 1.5 months. Good treatment compliance was mandatory for surgery, and treatment was continued immediately after extubation, in the recovery room, in nearly all patients, Dr. Series reported.
The analysis covered 1,103 patients: 447 controls (40.8%), 358 untreated (32.7%), 289 treated for OSA (26.4%) and 9 (0.8%) treated for OSA + hypoventilation. Patients with OSA, particularly those with severe OSA and those with hypoventilation, were older and heavier and significantly more likely to have hypertension and diabetes than controls.
There were no differences between the four groups in 10-day reoperation or 30-day readmission occurrence, and postoperative complications were “particularly infrequent in the control and OSA-untreated groups, with no differences between these two groups,” Dr. Series said.
Cardiac arrhythmia (mainly atrial fibrillation) occurred more frequently in the OSA-treated group (2.4%) and the OSA/hypoventilation patients (11%) than in the other groups (0.5%-0.6%).
Respiratory failure occurred in about one-third of patients with hypoventilation, and admission to the ICU was “dramatically higher” in patients with hypoventilation (67%), because of respiratory failure, arrhythmia, or other unstable medical conditions, Dr. Series said.
There were no differences between the groups in the duration of surgery or the amount of anesthetic used, but the length of stay in the recovery room was significantly longer in the OSA-treated and hypoventilation groups. The length of hospital stay was also longer in these groups. Sleeve gastrectomy was the most frequent bariatric surgical procedure across all groups, including 100% of patients with hypoventilation, he noted.
Asked to comment on the study, Octavian C. Ioachimescu, MD, PhD, of Emory University in Atlanta and the Atlanta Veterans Affairs Medical Center in Decatur, said the algorithm “clearly deserves further validation in other clinical-based cohorts and longer-term outcome assessment.”
Dr. Series reported that he has no relevant disclosures. Dr. Ioachimescu also said he has no relevant disclosures.

British protocol allows insulin-treated pilots to fly safely
A protocol developed in the United Kingdom that allows commercial pilots with insulin-treated diabetes to fly airplanes has resulted in precise glycemic control during flight and no safety issues, new research finds.
The results are believed to be the largest-ever dataset for people with insulin-treated diabetes in “safety-critical” occupations, said Gillian L. Garden, MD, who presented the findings this week at the virtual annual meeting of the European Association for the Study of Diabetes.
The protocol, which involves multiple glucose measurements before and throughout flights and corrective action for out-of-range values, resulted in 98% of glucose values in target range with no pilot incapacitation. The results were also published in Diabetes Care earlier this year, noted Dr. Garden, a clinical fellow in diabetes and endocrinology at the Royal Surrey NHS Foundation Trust, Guildford, England.
“There were no safety concerns at all and certainly no episodes of pilot incapacitation throughout the [7.5] years of the study. Our study proves that the protocol is feasible, is practical to implement, and is easily understood by both pilots and copilots,” she observed.
Dr. Garden foresees wider use of this approach: “We believe the study is of international importance and this protocol could be adopted by other aviation authorities to allow more insulin-treated pilots worldwide to be able to fly commercial aircraft.”
“With proper oversight and a defined protocol such as the one that we’ve been working to produce it is possible for anybody with insulin-treated diabetes to, in fact, adequately perform other safety-critical occupations as well, and it would be good to see fewer people being discriminated against on the basis of their diabetes,” she emphasized.
‘Impressive’ study of highly motivated individuals
Historically, insulin-treated patients – with both types of diabetes – had been barred from many “safety-critical” occupations, including commercial airline piloting. This was out of concern both for the potential immediate effects of hypoglycemia, including cognitive impairment and slowing of reaction times, as well as the long-term effects of diabetes, including vision loss and nerve damage, Dr. Garden explained.
However, “with advances in diabetes management, including different insulin types, methods of delivery, and glucose-monitoring systems, it’s now possible for individuals to have excellent glycemic control. This, along with the implementation of legislation against discrimination, has allowed insulin-treated people to no longer be debarred from certain employments,” she explained during an EASD press briefing on Sept. 24.
An expert panel convened in 2010 by the U.K. Civil Aviation Authority developed the protocol, and in 2012, the CAA began issuing class 1 medical certificates to insulin-treated pilots. The protocol was subsequently adopted by Ireland in 2015 and by Austria in 2016.
Initial results from nearly 9,000 glucose readings of 26 U.K. pilots who received a certificate between 2012 and 2015 were reported at the EASD 2016 Annual Meeting and published in 2017.
The current study is far larger, with 38,621 glucose readings from 49 pilots from the United Kingdom, Ireland, and Austria who have been using the protocol since 2012.
Mark Evans, MD, of Addenbrookes Hospital, Cambridge, England, said in an interview that “I thought this was a fascinating paper. ... I was deeply impressed by the data.”
Dr. Evans, who chairs the U.K. Department of Transport advisory panel on driving and diabetes, also noted: “The group of people with insulin-treated diabetes flying planes are a phenomenally motivated group who are prepared to do things that probably most drivers of motor vehicles would find oppressive or very difficult to do.”
“I thought the outcomes were really impressive in terms of the amount of time they were able to maintain themselves within glucose target ranges.”
Indeed, Dr. Garden said, “pilots are typically very organized and used to dealing with strict protocols with regard to all of the processes they have to follow before they fly and the safety checks they have to do. They adapted to this additional safety measure really well.”
Traffic light protocol keeps pilots in range
The protocol requires pilots to perform fingerstick glucose checks 30 minutes prior to flight, every hour during flight, and 30 minutes before landing. They must also attend clinical reviews every 6 months.
A traffic light system is used to denote acceptable pre- and in-flight glucose levels, with green meaning acceptable (5.0-15.0 mmol/L [90-270 mg/dL]), amber indicating caution for low (4.0-4.9 mmol/L [72-88 mg/dL]) or high (15.1-20.0 mmol/L [272-360 mg/dL]) blood glucose. Red requires immediate action (low blood glucose <4 mmol/L [72 mg/dL] and high >20 mmol/L [>360 mg/dL]).
Low amber values require the pilot to ingest 10-15 fast-acting carbohydrates and retest after 30 minutes. Low red values indicate the pilot must hand over the controls to the copilot. High readings of >15.0 mmol/L (>270 mg/dL) require an insulin dosing review. A high red value also requires the pilot to hand over the controls.
Of the 49 pilots, 84% had type 1 diabetes and 16% had insulin-treated type 2 diabetes. Most (61%) had class 1 medical certificates (required to validate a commercial pilot license) and 39% had class 2 medical certificates (required to validate a private pilot’s license). Median diabetes duration was 10.9 years.
Of note, all had become pilots prior to diabetes onset. As of now, the EU Aviation Safety Agency doesn’t allow people with preexisting insulin-treated diabetes to become pilots.
“We are fighting to change that, but with the U.K. leaving the EU, the Civil Aviation Authority might pursue it [separately]. We don’t know how that will pan out,” Dr. Garden noted during the briefing.
Over the 7.5 years, 97.7% of readings were within the green range, while just 1.42% were in the low amber range and 0.75% in the high amber range. Just 48 readings (0.12%) were in the low red range and 6 (0.02%) in the high red range. Of the 48 low reds, just 14 were recorded during flight. Of the six high reds, only two occurred during flight.
There were no instances of pilot incapacitation or changes in average hemoglobin A1c.
The results should alleviate concerns expressed after a prior report that pilots’ overall glycemic control could worsen if they pushed too hard to avoid lows, Dr. Garden noted.
The proportion of out-of-range values declined from 5.7% in 2013 to 1.2% in 2019. Low red values didn’t change (0.2% in 2013 and 0.1% in 2019) but high red values had completely disappeared by 2017.
What about CGM?
In response to a question during the briefing about use of continuous glucose monitoring, Dr. Garden said that some of the pilots were using CGM in addition to following the fingerstick protocol.
At the time the protocol was developed a decade ago, CGM wasn’t considered accurate enough and there wasn’t evidence for its use at high altitude.
But there has been a great deal more data since then, she said, noting “we believe it would be safer to use now because of how good that equipment is. ... Certainly, there’s a good number [of pilots] using CGM, and hopefully that will increase and the protocol will change to allow them all to use CGM if they want to.
“I think we’ll probably see CGM in the protocol within the next year to 2 years. Hopefully, that will make things a lot easier, so pilots won’t have to prick their fingers while they’re flying.”
Her group is currently conducting a study (DEXFLY) on use of the Dexcom G6 in addition to fingersticks in commercial pilots with insulin-treated diabetes. Results are expected by the end of the year.
Dr. Evans commented: “I think it’s a no-brainer that CGM will become the gold standard. I understand why they’re going to want to be cautious about this, but if they can generate data to show it will be a low-risk change, I think it will come.”
He also noted that it was only a couple of years ago that U.K. law was changed to allow car drivers with insulin-treated diabetes to use CGM as part of their glucose-testing requirements (before driving and every 2 hours). CGM still isn’t approved for use by drivers of trucks or other large vehicles, but “I think at some point in the future it will become more accepted,” Dr. Evans commented.
Dr. Garden reported no relevant financial relationships. Dr. Evans has reported being an advisory board member of, speaker for, and/or grant recipient from Novo Nordisk, Dexcom, Medtronic, Abbott, Eli Lilly, and Roche.
