A new draft consensus statement from the American Diabetes Association and the European Association for the Study of Diabetes (EASD) addresses diagnosis and management of type 1 diabetes in adults.  

The impetus for the document comes from the “highly influential” EASD-ADA consensus report on the management of type 2 diabetes, which led to the realization that a comparable document was needed for adults with type 1 diabetes, said writing panel cochair Anne L. Peters, MD, professor of clinical medicine at the University of Southern California, Los Angeles.

“In recent years, there have been rapid advances in the treatment of type 1 diabetes together with a growing recognition of the psychosocial burden of living with [it],” Dr. Peters said.

She noted that although there is already some guidance available for the management of type 1 diabetes in adults, “this gets admixed into broader guidelines, and many of those are mostly derived from data in people with type 2 diabetes.”  

The new draft document was coauthored by 14 content experts in type 1 diabetes, with equal numbers from the United States and Europe.
 

We want to be helpful to clinicians

Topics covered include diagnosis of type 1 diabetes, goals of therapy and glycemic targets, schedule of care, diabetes self-management education and additional behavioral considerations, glucose monitoring, insulin therapy, hypoglycemia, psychosocial care, diabetic ketoacidosis, pancreas and islet cell transplantation, adjunctive therapies, special populations (including pregnant women, older adults, and inpatient management), and emergent/future perspectives, including beta-cell replacement and immunotherapy.

At the end of the document are tables of glycemic targets for adults with type 1 diabetes, schedule of care, nonglycemic factors that alter A1c levels, standardized continuous glucose meter (CGM) metrics for clinical care, examples of subcutaneous insulin regimens, and the various properties of approved and nonapproved adjunctive therapies for type 1 diabetes, including metformin, pramlintide, GLP-1 agonists, and SGLT2 inhibitors.  

Several colorful flowcharts are also provided, including algorithms for diagnosing and managing type 1 diabetes in adults.

Document coauthor M. Sue Kirkman, MD, of the Diabetes Care Center’s Clinical Trials Unit at the University of North Carolina, Chapel Hill, told this news organization: “We want it to be helpful to clinicians who are diagnosing type 1 diabetes in adults or caring for adults with type 1 diabetes, whether diagnosed in childhood or adulthood.”

The authors presented an overview of the document in a symposium on June 28 at the virtual ADA scientific sessions. The final version will be presented Oct. 1 at the EASD 2021 annual meeting.

The draft document and video of the ADA meeting presentation are both available on the ADA website.
 

New algorithm to reduce misdiagnosis of type 1 diabetes in adults

Misdiagnosis of adult-onset type 1 diabetes is common, occurring in up to 40% of those who develop the condition after age 30 years, said J. Hans de Vries, MD, PhD, medical director, Profil Institute for Metabolic Research, Neuss, Germany.

There are multiple reasons for this, including the fact that obesity and type 2 diabetes are becoming more prevalent at younger ages, C-peptide levels may still be relatively high at the time of clinical type 1 diabetes onset, and islet autoantibodies don’t have 100% positive predictive value.

“No single feature confirms type 1 diabetes in isolation,” Dr. de Vries noted.

The document provides a detailed diagnostic algorithm specifically for adults in whom type 1 diabetes is suspected, starting with autoantibody measurement. If the diagnosis isn’t confirmed that way, the algorithm advises investigating for monogenic diabetes, including use of a maturity-onset diabetes of the young (MODY) calculator and subsequent C-peptide measurement.

Measurement of C-peptide is also recommended if the diabetes type is still uncertain more than 3 years after diabetes onset in those treated with insulin, because by that point it is likely to be <200 pmol/L in people with type 1 diabetes.  
 

Clear statements on diabetes technology, preferred insulins

The draft document clearly states that physiologic insulin replacement using a pump or multiple daily injections, CGM, and analog rather than human insulin are standards of care for adults with type 1 diabetes. Use of hybrid closed-loop insulin delivery systems is advised when available, as they offer the “greatest benefits.”

However, the document also notes that in cases of cost barriers, subcutaneous regimens of human regular and NPH insulin may be used. It cautions, though, that these may result in higher glucose variability, higher risk of hypoglycemia, and less lifestyle flexibility.

Dr. Kirkman told this news organization: “Using human insulins such as NPH and Regular in type 1 diabetes is definitely not preferred, but sometimes due to people’s inability to afford analogs we have to use them. People need to know how to use them safely.”

As for the do-it-yourself insulin delivery systems, which many with type 1 diabetes now use with open-source software algorithms that reverse-engineer older pumps, the document advises that health care providers shouldn’t actively recommend them as they’re not approved by regulatory authorities, but should also “respect the individual’s right to make informed choices and continue to offer support,” Dr. Kirkman said when presenting the insulin therapy section.
 

Psychosocial aspects of type 1 diabetes ‘underappreciated’

Special emphasis is placed on psychosocial support, which may be overlooked in adults, Dr. Kirkman noted.

“Clinicians probably underappreciate what people with type 1 diabetes go through on a daily basis. A lot of the evidence out there regarding psychosocial issues is in children and families of children with type 1 diabetes, or in adults with type 2 diabetes ... Maximizing quality of life needs to be at the forefront of care, not just focusing on glycemic goals.”

Indeed, between 20% and 40% of people with type 1 diabetes experience diabetes-related emotional distress – including 15% with depression – particularly at the time of diagnosis and when complications develop, noted Frank J. Snoek, PhD, professor of medical psychology at Amsterdam University Medical Center, the Netherlands.

To address this, the draft advises that “self-management difficulties, psychological, and social problems” be screened periodically and monitored using validated screening tools.

“Health care providers should be proficient at asking questions about and discussing emotional health, psychological needs, and social challenges as part of the consultation,” Dr. Snoek said.

Dr. Peters disclosed ties with Abbott Diabetes Care, AstraZeneca, Lilly, Medscape, Novo Nordisk, Vertex, and Zealand, Omada, and Teladoc. Dr. Kirkman has received research support from Novo Nordisk and Bayer. Dr. de Vries disclosed ties with Adocia, Novo Nordisk, Zealand, Eli Lilly, and Afon Technology. Dr. Snoek reported ties with Roche Diabetes, Novo Nordisk, Sanofi, and Eli Lilly.

A network meta-analysis of current first-line dual, triple, and quadruple therapies for Helicobacter pylori infection found that vonoprazan triple therapy was most effective, while standard triple therapy of a proton pump inhibitor (PPI), amoxicillin, and clarithromycin was least effective. Levofloxacin-containing triple therapy performed best in Western countries and West Asia, while reverse hybrid therapy was most effective in East Asia.

The results “[suggest that] a new approach concerning H. pylori treatment is now needed and that the time for transitioning from trial and error to antimicrobial stewardship [of H. pylori infection] has arrived,” wrote Theodore Rokkas, PhD, MD, of the European University of Cyprus in Engomi, and colleagues. Their study was published online April 8 in Gastroenterology.

H. pylori infection is the primary cause of gastritis, peptic ulcer disease, gastric mucosa–associated lymphoid tissue lymphoma, and gastric cancer.

Since H. pylori infection was first recognized, physicians have employed a range of drugs in double, triple, and quadruple combinations to combat it.

Despite those efforts, treatment success is lower than with many other infectious diseases. A newcomer is the potassium-competing acid blocker vonoprazan, which increases efficacy of amoxicillin combination therapies and has, thereby, generated renewed interest in all combination therapies, according to the study authors. Vonoprazan is currently available in some Asian countries, but not the United States or Europe.

Current guidelines for H. pylori treatment relied on randomized controlled trials and relevant pair-wise meta-analyses, but no previous pairwise analysis has included all currently available medications, the authors noted. Network meta-analyses can help fill this evidence gap: They incorporate both direct and indirect evidence from a collection of randomized controlled trials to estimate the comparative effectiveness of three or more regimens.

The researchers conducted a network meta-analysis that included 68 randomized, controlled trials totaling 22,975 patients. The following regimens were included in the analysis: Concomitant quadruple bismuth treatment (bismuth quadruple therapy), concomitant quadruple nonbismuth treatment (nonbismuth quadruple therapy), high-dose amoxicillin double treatment (Amox-dual therapy), levofloxacin-containing treatment (Levo-therapy), reverse hybrid therapy (R-hybrid therapy), sequential quadruple treatment (sequential therapy), standard triple treatment (triple therapy), and vonoprazan-containing therapy (Vono-triple therapy).

Statistically significant results were found with Vono-triple therapy versus triple therapy (odds ratio, 3.80; 95% confidence interval, 1.62-8.94), sequential therapy versus triple therapy (OR, 1.79; 95% CI, 1.26-2.53), nonbismuth quadruple therapy versus triple therapy (OR, 2.08; 95% CI, 1.45-2.98), bismuth quadruple therapy versus triple therapy (OR, 1.47; 95% CI, 1.02-2.11), and Levo-therapy versus triple therapy (OR, 1.79; 95% CI, 1.26-2.53).

In the overall data, mean cure rates greater than 90% were seen only in Vono-triple therapy (91.4%; 95% CI, 88.5-93.5%) and R-hybrid therapy (93.6%; 95% CI, 90.4-96.8%). Cure rates were lower for Nonbismuth quadruple therapy (84.3%; 95% CI, 82.7-85.8%), Levo-therapy (83.8%; 95% CI, 82.1-85.4%), Sequential therapy (83.7%; 95% CI, 82.7-84.7%), bismuth quadruple therapy (81.3%; 95% CI, 79.5-83.1%), Amox-dual therapy (80.2%; 75.3%-84.4%), and triple therapy (75.7%; 95% CI, 74.9-76.4%). Levo-therapy performed best in Western countries (88.5%; 95% CI, 86.5-90.5%) and West Asia (88.4%; 95% CI, 84.6-91.1%). R-hybrid therapy performed best in East Asia (93.6%; 95% CI, 90.4-96.8%).

A surface under the cumulative ranking (SUCRA) value, which represents the efficacy of the intervention compared to an ideal intervention, was 92.4% for Vono-triple therapy. The second highest SUCRA value was for 68.8% for nonbismuth quadruple therapy. The SUCRA value of standard triple therapy was 4.7%.

A key limitation to the study is that Vono-triple therapy was tested only in Japan, and requires additional study in other geographic regions.

The study received support from the Department of Veteran Affairs. The authors have consulted for and received research funding from various pharmaceutical companies.

In a small study of Hirschsprung’s disease (HSCR) patients, those with a low-fiber colonic mucosal acetylcholinesterase-positive (AChE+) innervation phenotype were more likely to suffer from postoperative enterocolitis, which can be life-threatening.

The study lends insight into crosstalk between the human enteric nervous and immune systems. It suggests a role for acetylcholine-secreting (cholinergic) nerve fibers in aganglionic sections of colon in patients with HSCR, which is a congenital disorder marked by the absence of enteric neuronal cells in the distal part of the gut.

There are also potential clinical implications. “These observations suggest that HSCR patients with low-fiber phenotype might have a higher risk of developing postoperative enterocolitis and that the fiber phenotype could serve as a predictive marker for development of prophylactic therapy,” wrote Simone Keck, PhD,  of the University of Basel (Switzerland) and colleagues in a study published in Cellular and Molecular Gastroenterology and Hepatology.

HSCR is a multigenetic congenital condition that includes a lack of enteric ganglia cells (aganglionosis) in the distal part of the colon, leading to intestinal obstruction and prestenotic megacolon. Treatment consists of pull-through surgery to remove the aganglionic portion of the bowel, but 20%-50% of patients develop life-threatening HSCR-associated enterocolitis before or after surgery. Although the mechanism of the complication is uncertain, immune cells, intestinal barrier function, and the microbiome may play a role.

Mouse models have shown connections between the immune and nervous system, but it has been challenging to study the effects of specific neurotransmitters in humans. There are more than 30 separate neurotransmitters in the enteric nervous system, making it difficult to tease apart individual functions. But there are comparatively few enteric nervous system neurotransmitters in patients with HSCR and the aganglionic colon in these patients contains enlarged AChE+ nerve fibers, “neuronal cholinergic function can be examined particularly well” among these patients. .

The researchers of the current study from analyzed tissue from 44 pediatric HSCR patients who underwent pull-through surgery, along with 6 non-HSCR controls who had surgery for various other reasons. Tissue samples were semiquantitatively categorized according to the extent of colonic mucosal AChE+ innervation: Low-fiber rectosigmoid tissue lacked intrinsic nerve cell bodies and mucosal ACHe+ innervation, while high-fiber tissue lacked nerve cell bodies but had mucosal AChE+ innervation. The researchers also determined tissue cytokine profile and immune cell frequencies, and used confocal immunofluorescence microscopy to determine proximity of macrophages to nerve fibers and 16S-rDNA sequencing to determine microbial populations.

They found that aganglionic low-fiber samples had higher levels of inflammatory cytokines such as interleukin-17, IL-1-beta, and IL6. Levels of these cytokines were lower in both ganglionic sections of the colon and in high-fiber samples with mucosal AChE+ nerve fibers. Low-fiber samples also had elevated Th17 T cells, compared with high-fiber, aganglionic, and ganglionic distal colon samples. Regulatory T cells were highest in cholinergic high-fiber segments.

Out of 42 patients, 9 developed enterocolitis within 1 year of surgery; 7 had a low-fiber phenotype, while 2 were high-fiber. This difference was not statistically significant, but the researchers then performed a retrospective analysis of 29 HSCR patients to validate the findings. Of these, 14 developed enterocolitis after surgery, with 12 of the cases occurring among children with the low-fiber phenotype, and 2 cases occurred among those with the high-fiber phenotype.

The findings could help guide postsurgical management of HSCR by allowing clinicians to employ preventive measures against enterocolitis, such as high-volume enemas, antibiotics, prebiotics, probiotics, or dietary changes. Th17 cells are known to migrate to nearby mesenteric lymph nodes, where they may promote enterocolitis, and this site is usually not removed during HSCR surgery. Fiber phenotype could prompt a surgeon to also remove mesenteric lymph nodes to reduce enterocolitis risk. A potential therapeutic strategy is to target IL-17 or IL-23.

The study was funded by the University of Basel. The authors have no relevant financial disclosures.

Over the last several years, the United States has seen a substantial increase in proposed legislation directed toward transgender individuals, particularly youth.¹ One type of this legislation aims to prevent participation of transgender girls on female sports teams. While at first glance these bills may seem like common sense protections, in reality they are based on little evidence and serve to further marginalize an already-vulnerable population.

The majority of the population, and thus the majority of athletes, are cisgender.² According a limited data set from the 2017 Youth Risk Behavior Survey, only 1.8% of high school students identify as transgender.^3,4 Overall, this is a very small percentage and it is unlikely that all of them, or even a majority, participate in athletics. In fact, many transgender individuals avoid athletics as it worsens their dysphoria. Winners are no more likely to be transgender than cisgender.

While proponents of this legislation say that trans women have an unfair advantage because of elevated testosterone levels (and thus theoretically increased muscle mass), there is no clear relationship between higher testosterone levels in athletes and improved athletic performance.² In fact, there are plenty of sports in which a smaller physique may be beneficial, such as gymnastics. A systematic review showed “no direct or consistent research suggesting transgender female individuals ... have an athletic advantage at any stage of their transition.”⁵ Furthermore, trans women are not the only women with elevated testosterone levels. Many cisgender women who have polycystic ovary syndrome or a disorder of sexual differentiation can have higher levels of testosterone and theoretically may have higher muscle mass. Who is to decide which team would be most appropriate for them? Is the plan to require a karyotype, other genetic testing, or an invasive physical exam for every young athlete? Even if the concern is with regards to testosterone levels and muscle mass, this ignores that fact that appropriate medical intervention for transgender adolescents will alter these attributes. If a transgender girl began gonadotropin-releasing hormone agonists early in puberty, she is unlikely to have increased muscle mass or a higher testosterone level than a cisgender girl. Those trans girls who take estradiol also experience a decrease in muscle mass. Additionally, adolescents grow and develop at different rates – surely there is already significant variability among hormone levels, muscle mass, sexual maturity ratings, and ability among individual athletes, regardless of gender identity? The argument that trans women should be excluded based on a theoretical genetic advantage is reminiscent of the argument that Black athletes should be excluded because of genetic advantage. Just as with cisgender athletes, transgender athletes will naturally vary in ability.⁶

In addition, there are many places and organizations that already have trans-inclusive policies in place for sports, yet we have not seen transgender individuals dominate their peers. In the 8 years since implementation of a trans-inclusive sports policy in California, a trans woman has never dominated a sport.⁷ The same is true for Canada since the institution of their policy 2 years ago. While transgender people can participate in the Olympics, this year marks the first time a trans woman has ever qualified (Laurel Hubbard, New Zealand, women’s weightlifting). The lack of transgender Olympians may be in part because of problematic requirements (such as duration of hormone therapy and surgery requirements) for transgender individuals, which may be so onerous that they are functionally excluded.^2,5

In reality, athletes are improving over time and the performance gap between genders is shrinking. For example, in 1970 Mark Spitz swam the 100-meter freestyle in 51.94 seconds, a time that has now been surpassed by both men and women, such as Sarah Sjöström (women’s world record holder at 51.71 seconds). Athletes’ physical attributes are often less important than their training and dedication to their sport.

More importantly, this discussion raises the philosophical question of the purpose of athletics for youth and young adults. Winning and good performance can – though rarely – lead to college scholarships and professional careers, the biggest benefit of athletics comes from participation. We encourage youth to play sports not to win, but to learn about leadership, dedication, and collegiality, as well as for the health benefits of exercise. Inclusion in sports and other extracurricular activities improves depression, anxiety, and suicide rates. In fact, participation in sports has been associated with improved grades, greater homework completion, higher educational and occupational aspirations, and improved self-esteem.^8-12 Excluding a population that already experiences such drastic marginalization will cause more damage. Values of nondiscrimination and inclusion should be promoted among all student athletes, rather than “other-ism.”

Forcing trans women to compete with men will worsen their dysphoria and further ostracize the most vulnerable, giving credence to those that believe they are not “real women.” Allowing transgender individuals to play on the team consistent with their gender identity is appropriate, not only for scientific reasons but also for humanitarian ones. Such laws are based not on evidence, but on discrimination. Not only do trans women not do better than cisgender women in sports, but such proposed legislation also ignores the normal variability among individuals as well as the intense training and dedication involved in becoming a top athlete. Limiting trans women’s participation in sports does not raise up cisgender women, but rather brings us all down. Please advocate for your patients to participate in athletics in accordance with their gender identity to promote both their physical and emotional well-being.

A 46-year-old woman presents with fatigue. She reports that she has had unusually heavy periods for the past 6 months. Her blood work shows a hematocrit level of 32, a mean corpuscular volume of 77, a platelet count of 390,000, and a ferritin level of 5.

What would you recommend for iron replacement?

A. FeSO₄ 325 mg three times a day with vitamin C

B. FeSO₄ 325 mg daily with vitamin C

C. FeSO₄ 325 mg every other day

Recommendations and supporting research

I think I would start with choice C, FeSO₄ every other day.

Treatment of iron deficiency with oral iron has traditionally been done by giving 150-200 mg of elemental iron (which is equal to three 325 mg tablets of iron sulfate).¹ This dosing regimen has considerable gastrointestinal side effects. Recent evidence has shown that iron absorption is diminished the more frequently it is given.

Stoffel and colleagues found that fractional iron absorption was higher in iron-deficient women who were given iron every other day, compared with those who received daily iron.² They also found that the more frequently iron was administered, the higher the hepcidin levels were, and the lower the iron absorption.

Karacok and colleagues studied every other day iron versus daily iron for the treatment of iron-deficiency anemia of pregnancy.³ A total of 217 women completed randomization and participated in the study, with all women receiving 100 mg of elemental iron, either daily (111) or every other day (106). There was no significant difference in increase in ferritin levels, or hemoglobin increase between the groups. The daily iron group had more gastrointestinal symptoms (41.4%) than the every other day iron group (15.1%) (P < .0057).

Düzen Oflas and colleagues looked at the same question in nonpregnant women with iron deficiency anemia.⁴ Study patients either received 80 mg iron sulfate twice a day, 80 mg once a day, or 80 mg every other day. There was no statistically significant difference in hemoglobin improvement between groups, but the group that received twice a day dosing of iron had statistically significantly higher ferritin levels than the daily or every other day iron groups. This improvement in ferritin levels came at a cost, though, as 68% of patients in the twice daily iron group had gastrointestinal symptoms, compared with only 10% in the every other day iron group (P < .01).

Vitamin C is often recommended to be taken with iron to promote absorption. The evidence for this practice is scant, and dates back almost 50 years.^5,6

Cook and Reddy found there was no significant difference in mean iron absorption among the three dietary periods studied in 12 patients despite a range of mean daily intakes of dietary vitamin C of 51-247 mg/d.⁷

Hunt and colleagues studied 25 non pregnant, healthy women with low ferritin levels.⁸ The women’s meals were supplemented with vitamin C (500 mg, three times a day) for 5 of the 10 weeks, in a double-blind, crossover design. Vitamin C supplementation did not lead to a difference in iron absorption, lab indices of iron deficiency, or the biological half-life of iron.

Li and colleagues looked at the effect of vitamin C supplementation on iron levels in women with iron deficiency anemia.⁹ A total of 440 women were recruited, with 432 completing the trial. Women were randomized to receive iron supplements plus vitamin C or iron supplements only. Their findings were that oral iron supplements alone were equivalent to oral iron supplements plus vitamin C in improving hemoglobin recovery and iron absorption.
 

Bottom line

Less frequent administration of iron supplements (every other day) is as effective as more frequent administration, with less GI symptoms. Also, adding vitamin C does not appear to improve absorption of iron supplements.

A 46-year-old woman presents with fatigue. She reports that she has had unusually heavy periods for the past 6 months. Her blood work shows a hematocrit level of 32, a mean corpuscular volume of 77, a platelet count of 390,000, and a ferritin level of 5.

What would you recommend for iron replacement?

A. FeSO₄ 325 mg three times a day with vitamin C

B. FeSO₄ 325 mg daily with vitamin C

C. FeSO₄ 325 mg every other day

Recommendations and supporting research

I think I would start with choice C, FeSO₄ every other day.

Treatment of iron deficiency with oral iron has traditionally been done by giving 150-200 mg of elemental iron (which is equal to three 325 mg tablets of iron sulfate).¹ This dosing regimen has considerable gastrointestinal side effects. Recent evidence has shown that iron absorption is diminished the more frequently it is given.

Stoffel and colleagues found that fractional iron absorption was higher in iron-deficient women who were given iron every other day, compared with those who received daily iron.² They also found that the more frequently iron was administered, the higher the hepcidin levels were, and the lower the iron absorption.

Karacok and colleagues studied every other day iron versus daily iron for the treatment of iron-deficiency anemia of pregnancy.³ A total of 217 women completed randomization and participated in the study, with all women receiving 100 mg of elemental iron, either daily (111) or every other day (106). There was no significant difference in increase in ferritin levels, or hemoglobin increase between the groups. The daily iron group had more gastrointestinal symptoms (41.4%) than the every other day iron group (15.1%) (P < .0057).

More Americans died from drug overdoses in 2020 than in any other year, the CDC said July 14.

Fatal overdoses rose by nearly 30% last year to a total of more than 93,000 deaths, according to the provisional data the National Center for Health Statistics reported.

The spikes are largely attributed to the rise in use of fentanyl and other synthetic opioids.

The Washington Post reported that more than 69,000 overdose deaths involved opioids, up from 50,963 in 2019.

Amid the crush of overdoses, the White House announced that President Joe Biden has nominated Rahul Gupta, MD, to lead the White House Office of National Drug Control Policy.

Dr. Gupta is a former health commissioner of West Virginia, and is chief medical and health officer for the March of Dimes.

“Dr. Gupta led efforts in West Virginia to address the opioid crisis, gaining national prominence as a leader in tackling this issue,” March of Dimes President and CEO Stacey Stewart said in a statement. “At March of Dimes, he has advocated for policies and programs to prevent and treat substance use, with a focus on the safety and care of pregnant women and infants.”

The overactive bladder treatment mirabegron (Myrbetriq) is one of three new drugs to be linked to cases of drug-associated antineutrophil cytoplasmic antibody–associated vasculitis (DA-AAV) according to pharmacovigilance data.

Artfoliophoto/Thinkstock

The other two drugs are the antiviral agent sofosbuvir (Sovaldi) and the tyrosine kinase inhibitor nintedanib (Ofev), which is indicated for chronic fibrosing interstitial lung diseases (ILDs) with a progressive phenotype.

The study findings also strengthen previously suspected associations, Samuel Deshayes, MD, of Caen (France) University Hospital and coauthors report in Arthritis & Rheumatology. This includes associations between hydralazine, propylthiouracil, thiamazole, minocycline, and carbimazole to name a few more of the 15 drugs where associations were found.

“These data imply specific prescriber attention to these drugs and argue for experimental studies on AAV pathophysiology with [the] recent drugs,” Dr. Deshayes and colleagues wrote.

Identifying whether AAV could be due to drug treatment is important as there have been suggestions that this may confer a better prognosis than for primary AAV. In addition, “withdrawal of the culprit drug” may be enough to treat the patient in milder cases, the researchers suggested.

That said, the researchers acknowledged that it can be difficult to attribute AAV to a specific drug, particularly as data are often from case reports or small series of patients and, until now, research had considered older medications.

To update current knowledge and include newer treatments, Dr. Deshayes and associates took data from the World Health Organization pharmacovigilance database (VigiBase) and performed a retrospective analysis.

They collected data on all adverse drug reactions (ADRs) reported using the Medical Dictionary for Drug Regulatory Activities preferred term ‘anti-neutrophil’ cytoplasmic antibody positive vasculitis’ from its introduction in 2006 up until November 2020.

Drugs used in the management of AAV, such as azathioprine, cyclophosphamide, leflunomide, and methotrexate, among others, were not included in the analysis “due to potential indication bias,” they explained.

Among 483 individual “deduplicated” case safety reports, most cases of DA-AAV were reported in women (71.2% of cases) and the median age at onset was 62 years. The median time to develop AAV after drug initiation was 9 months.

DA-AAV was considered serious in almost all (98%) of the reported cases, meaning that it was life-threatening, had resulted in or had prolonged hospital treatment, caused significant or persistent disability or other anomalies such as birth defects, or resulted in the death of the individual. With regard to the latter, DA-AAV was reported as fatal in 8.9% of cases.

The highest rates of reported DA-AAV were seen in people treated with the antihypertensive drug hydralazine, the antithyroid drugs propylthiouracil, thiamazole, and carbimazole, the antibiotic minocycline, mirabegron, sofosbuvir, and nintedanib.

A further seven drugs were also linked to cases of AAV, bringing the total to list to 15 drugs associated with overreporting of AAV. This included the heavy metal antagonist penicillamine, the influenza vaccine, the gout medication allopurinol, the anti-tuberculosis drug rifampin, the antiviral agent peginterferon alfa-2b, the anti-asthma drug montelukast, and the anti-cholesterol agent rosuvastatin.

Dr. Deshayes and coauthors pointed out that the associations do not imply causality. The data mining approach used allowed for the “automated detection of drug safety signals associated with rare events such as AAV,” they said.

There are limitations, they acknowledged, which are common to studies that use pharmacovigilance data. For one, “notoriety bias” could be at play. This is where there is an “increased number of reports after safety alerts in the media.” Missing data, “including delay between the introduction of the drug and AAV,” could be a factor, as could “bias related to its retrospective and declarative design.”

The study received no commercial funding. All study authors declared no competing interests.

On July 12, federal officials announced they are seeking to establish a national coverage policy for aducanumab (Aduhelm) for Alzheimer’s disease (AD), a process that will take until next year to complete.

The Centers for Medicare & Medicaid Services said it will accept public comments about how Medicare should cover aducanumab through Aug. 11. The agency intends to post a draft decision memo on its coverage approach by Jan. 12, 2022, and then finalize this policy by April 12. Coverage decisions about aducanumab now are being made at the local level by Medicare’s administrative contractors, CMS said in a press release.

The announcement followed separate public calls for such a review by America’s Health Insurance Plans (AHIP) and the Alzheimer’s Association.

On June 30, AHIP submitted a formal request to the CMS. In it, AHIP requests that CMS take “swift action” on a national coverage determination for aducanumab. In the request, the organization specifically urged CMS to use a policy known as coverage with evidence development (CED) for Aduhelm.

This CED approach would allow access for patients considered most likely to benefit from the drug while Biogen continues research needed to definitively show its clinical benefit, said AHIP chief executive Matt Eyles.

In June, the Food and Drug Administration approved aducanumab based on data suggesting the drug might slow AD progression using the surrogate marker of a reduction in amyloid plaque.

The FDA’s accelerated approval letter set a 2030 deadline for Biogen to produce evidence from a phase 3 clinical trial definitively proving the drug’s efficacy.
 

Hefty price tag

Even if Biogen meets the FDA’s deadline, patients with AD, their families, clinicians, and insurers likely will wrestle for years with questions about whether to use this costly drug without clear evidence of benefit. The drug is estimated to cost $56,000 per year.

In addition, patients taking the drug will be required to undergo MRI scans to monitor for brain swelling or bleeding, complications that were experienced by those participating in previous studies of the drug, Mr. Eyles noted in his letter to CMS, which AHIP provided to this news organization.

About 80% of those eligible for aducanumab in the United States are enrolled in Medicare, write James D. Chambers, PhD, MPharm, Tufts University, Boston, and coauthors in a June article in the journal Health Affairs. Like AHIP, these authors also recommended CMS consider the CED path for the drug.

CMS has used the CED approach since 2003 to evaluate interventions such as amyloid PET for clinical evaluation of AD to implantable cardioverter defibrillators.

Applying CED to aducanumab “would provide the medical community, patients, caregivers, and payers with additional information long before the FDA’s required postapproval studies are completed,” Dr. Chambers and coauthors wrote. “It would also ensure that data on every patient treated would add to the knowledge base about how aducanumab impacts patient outcomes such as cognition, function, and quality of life.”

In the AHIP request to CMS, Mr. Eyles also noted that an independent review organization, the Institute for Clinical and Economic Review, said the evidence from studies done to date on aducanumab is “insufficient” to show a net health benefit for patients with mild cognitive impairment because of AD or mild AD.

At the ICER meeting, which will take place July 15, one of ICER’s expert panels, the California Technology Assessment Forum, said it will further consider all of the available scientific data on aducanumab and vote on a series of questions about its efficacy and value.

ICER’s reports have clout because insurers use its recommendations to help determine how to cover drugs and medical treatments. Among the questions ICER has posted online ahead of the meeting is one about the relative effects of aducanumab plus supportive care versus supportive care alone.
 

‘Dark irony’

Even as the medical community waits for Biogen to present clear evidence of a benefit for aducanumab, clinics specializing in AD may get a financial boost, said Jason Karlawish, MD, professor of medicine, medical ethics, health policy, and neurology at the University of Pennsylvania, Philadelphia, and codirector of Penn’s Memory Center.

Some clinicians see the arrival of the drug as a “win” for the field despite lingering concerns about its approval, said Dr. Karlawish at a panel discussion held July 12 by the nonprofit Hastings Center, a bioethics research institute. Dr. Karlawish is a fellow at Hastings.

In May, Dr. Karlawish published an article in STAT titled “If the FDA approves Biogen’s Alzheimer’s treatment, I won’t prescribe it.” Dr. Karlawish told this news organization that he was a site investigator for Biogen studies of aducanumab and has worked on studies sponsored by Lilly and Eisai.

During the discussion July 12, Dr. Karlawish said he had altered his view and now might be a “reluctant prescriber.” This shift is because of his commitment “to preserve, protect and defend their autonomy” of patients with AD.

He also noted the drug could draw more money into the field to help care for patients with AD by providing increased access to diagnostics. Additionally, funds provided to clinics for administering aducanumab will aid specialty memory centers, “which have been basically impoverished since their creation,” Dr. Karlawish said.

“There is a dark irony that it takes a questionably beneficial drug to bring in the revenue to finally get memory centers up and functioning,” Dr. Karlawish said, adding that there needs to be “a larger conversation about how a big, vast, and problematic disease is being treated.”

Aducanumab’s approval shows that diseases in the U.S. are not fully considered as diseases until they have “a business model, and much of that business model relies on the pharmaceutical industry,” he noted.
 

Dr. Woodcock’s ‘personal commitment’

In early July, the FDA took two highly publicized steps to address criticism of its handling of the aducanumab approval. It revised the drug’s label to limit its use to patients with mild cognitive impairment likely related to AD or those in the mild stages of the disease.

In addition, Janet Woodcock, MD, the FDA’s acting commissioner, took to Twitter and posted a letter she sent to the Office of the Inspector General that called for a federal investigation into the drug’s approval that would examine agency staff interactions with Biogen.

AHIP spokesperson Kristine Grow said July 12 that her organization is still seeking a national Medicare coverage decision, but that the label revision was a “step in the right direction.”

“Patients with Alzheimer’s disease, and their families and caregivers, deserve safe, effective treatments. We applaud the FDA for this label adjustment, which brings indicated patients a bit closer to those included in clinical trials,” Ms. Grow said in an interview.

“At the same time, we remain concerned about the limited clinical evidence demonstrating efficacy and the serious safety risks that aducanumab poses for patients. We look forward to additional information from the FDA and other regulators, including CMS’ coverage guidance for patients who are Medicare eligible,” she added.

The controversy surrounding the approval of aducanumab is drawing more attention to the lack of a confirmed FDA commissioner. But in her letter to OIG, Dr. Woodcock wrote as if she intends to remain at the helm of the agency for at least a while longer. She wrote in her letter that OIG has her “personal commitment” that the FDA will fully cooperate if the investigative unit decides to undertake a review.

Dr. Woodcock also urged that a review be conducted as soon as possible, noting “should such a review result in actionable items, you also have my commitment to addressing these issues.”

A former FDA adviser who resigned over the agency’s handling of aducanumab said July 12 there needs to be a broader investigation of the FDA’s actions.

Attending the Hastings Center event was Aaron S. Kesselheim, MD, JD, MPH, of Harvard Medical School, Boston, one of three former members of an FDA advisory committee who resigned over the agency’s handling of aducanumab. Dr. Kesselheim said in an interview that he has no financial relationships to disclose in connection with this discussion.

“I would suggest that instead all aspects of this approval process should be investigated,” Dr. Kesselheim said, including the relationship between FDA and Biogen.

Dr. Karlawish said he was also concerned that Dr. Woodcock’s request for an investigation was “very narrow,” and noted members of Congress have said they are examining the FDA’s handling of this drug.

In a July 9 joint statement, House Committee on Energy and Commerce Chairman Frank Pallone Jr (D-N.J.), and House Committee on Oversight and Reform Chairwoman Carolyn B. Maloney (D-N.Y.) said they were “pleased” by Dr. Woodcock’s announcement, but they will keep digging into ongoing questions about the drug. In their view, the OIG review of FDA staff interactions with Biogen officials would complement their committees’ “robust investigation of this matter.”

“We continue to have concerns about the approval process for Aduhelm, how Biogen set its price, and the implications for seniors, providers, and taxpayers,” Mr. Pallone and Ms. Maloney added.

On July 12, federal officials announced they are seeking to establish a national coverage policy for aducanumab (Aduhelm) for Alzheimer’s disease (AD), a process that will take until next year to complete.

The Centers for Medicare & Medicaid Services said it will accept public comments about how Medicare should cover aducanumab through Aug. 11. The agency intends to post a draft decision memo on its coverage approach by Jan. 12, 2022, and then finalize this policy by April 12. Coverage decisions about aducanumab now are being made at the local level by Medicare’s administrative contractors, CMS said in a press release.

The announcement followed separate public calls for such a review by America’s Health Insurance Plans (AHIP) and the Alzheimer’s Association.

On June 30, AHIP submitted a formal request to the CMS. In it, AHIP requests that CMS take “swift action” on a national coverage determination for aducanumab. In the request, the organization specifically urged CMS to use a policy known as coverage with evidence development (CED) for Aduhelm.

This CED approach would allow access for patients considered most likely to benefit from the drug while Biogen continues research needed to definitively show its clinical benefit, said AHIP chief executive Matt Eyles.

In June, the Food and Drug Administration approved aducanumab based on data suggesting the drug might slow AD progression using the surrogate marker of a reduction in amyloid plaque.

The FDA’s accelerated approval letter set a 2030 deadline for Biogen to produce evidence from a phase 3 clinical trial definitively proving the drug’s efficacy.
 

Hefty price tag

Even if Biogen meets the FDA’s deadline, patients with AD, their families, clinicians, and insurers likely will wrestle for years with questions about whether to use this costly drug without clear evidence of benefit. The drug is estimated to cost $56,000 per year.

In addition, patients taking the drug will be required to undergo MRI scans to monitor for brain swelling or bleeding, complications that were experienced by those participating in previous studies of the drug, Mr. Eyles noted in his letter to CMS, which AHIP provided to this news organization.

About 80% of those eligible for aducanumab in the United States are enrolled in Medicare, write James D. Chambers, PhD, MPharm, Tufts University, Boston, and coauthors in a June article in the journal Health Affairs. Like AHIP, these authors also recommended CMS consider the CED path for the drug.

CMS has used the CED approach since 2003 to evaluate interventions such as amyloid PET for clinical evaluation of AD to implantable cardioverter defibrillators.

Applying CED to aducanumab “would provide the medical community, patients, caregivers, and payers with additional information long before the FDA’s required postapproval studies are completed,” Dr. Chambers and coauthors wrote. “It would also ensure that data on every patient treated would add to the knowledge base about how aducanumab impacts patient outcomes such as cognition, function, and quality of life.”

In the AHIP request to CMS, Mr. Eyles also noted that an independent review organization, the Institute for Clinical and Economic Review, said the evidence from studies done to date on aducanumab is “insufficient” to show a net health benefit for patients with mild cognitive impairment because of AD or mild AD.

At the ICER meeting, which will take place July 15, one of ICER’s expert panels, the California Technology Assessment Forum, said it will further consider all of the available scientific data on aducanumab and vote on a series of questions about its efficacy and value.

ICER’s reports have clout because insurers use its recommendations to help determine how to cover drugs and medical treatments. Among the questions ICER has posted online ahead of the meeting is one about the relative effects of aducanumab plus supportive care versus supportive care alone.

Congenital onychodysplasia of the index finger (COIF), or Iso-Kikuchi syndrome, is a rare disorder characterized by malformation of one or both nails of the index fingers. The various anomalies described are anonychia, micronychia, polyonychia, malalignment, or hemi-onychogryphosis. It may be associated with abnormalities of the underlying phalangeal bone, the most masked being bifurcation of the terminal phalange.¹ Initially thought to be nonhereditary and nonfamilial,² it is now known that COIF can be inherited in an autosomal-dominant fashion.³ Millman and Strier³ described a family of 9 patients with COIF. It rarely is described outside of Japan. Padmavathy et al⁴ described a case in an Indian patient with COIF that was associated with the absence of a ring finger in addition to anomalies of the metacarpal bones.

Congenital onychodysplasia of the index finger has a broad spectrum regarding its etiology and clinical features.⁵ The pathogenesis of COIF still is poorly understood. Deficient circulation in digital arteries is thought to be a putative mechanism for developing a deformed nail. The nail is affected on the radial side of the index finger, likely because of the smaller caliber of the artery on that side.⁵ Hereditary as well as nonhereditary sporadic cases have been reported. In addition to the various fingernail anomalies, skeletal abnormalities also have been reported. Baran and Stroud⁶ have reported deformed lunulae as a manifestation of COIF.

The Diagnosis: Congenital Onychodysplasia of the Index Finger

The differential diagnosis of COIF includes hidrotic ectodermal dysplasia, nail-patella syndrome, Poland syndrome, and DOOR syndrome. Hidrotic ectodermal dysplasia exhibits onychodystrophy, generalized hypotrichosis, palmoplantar keratoderma, and dental anomalies.⁷ Nail-patella syndrome presents with hypoplasia of the fingernails and toenails, triangular nail lunulae, absent or hypoplastic patellae, and elbow and iliac horn dysplasia. Poland syndrome is distinguished from COIF by the congenital absence of the pectoralis major muscle on the ipsilateral side of the involved digits. The DOOR syndrome tetrad is comprised of deafness, onychodystrophy, osteodystrophy, and mental retardation.⁸ Unlike these conditions, COIF does not involve systems other than the nails and phalanges.

Treatment of this condition is mainly conservative, as patients typically do not have symptoms.⁹ Surgical interventions can be considered for cosmetic concerns. Knowledge of this congenital entity and its clinical findings is essential to prevent unnecessary procedures and workup.

Dancing helps slow the progression of motor and nonmotor symptoms and improves quality of life for patients with Parkinson’s disease (PD), new research shows.

Over 3 years, weekly participation in dance training classes “drastically” reduced the expected decline in motor function and significantly improved speech, tremors, balance, and stiffness, the researchers reported.

Dance training also appeared to have benefits regarding cognition, hallucinations, depression, and anxiety.

“These findings strongly suggest the benefits of dance for people with PD as a supplement to a normal treatment regimen,” the investigators noted.

Although the mechanism of benefit is unclear, dance training may help “train neural network nodes that helps either strengthen networks damaged or builds neural road maps that pass the damage,” study investigator Joseph DeSouza, PhD, principal investigator and associate professor, department of psychology, York University, Toronto, said in an interview.

The study was published online July 7, 2021, in Brain Sciences.
 

Multiple benefits

PD is a neurodegenerative disease associated with progression of motor dysfunction within the first 5 years of diagnosis. The annual rate of motor decline, as determined with the Movement Disorder Society Unified Parkinson’s Disease Rating Scale (MDS-UPDRS), is between 5.2 and 8.9 points.

Prior studies that assessed various styles of dance by patients with PD showed beneficial effects regarding gait speed, balance, locomotion, and aspects of quality of life.

To investigate further, DeSouza and coauthor Karolina Bearss, a PhD candidate at York University, followed 16 patients with mild to moderate PD who participated in a weekly dance class at Canada’s National Ballet School and Trinity St. Paul’s church.

Dance for Parkinson’s Disease, which is an established dance curriculum, involves aerobic and anaerobic movements. The protocol begins with a seated warm-up, followed by barre work, and ends with moving across the floor. All participants learn choreography for an upcoming performance.

In the study, 16 patients with PD who did not participant in the dance classes served as control patients.

Over 3 years, the daily rate of motor decline, as indicated by scores on part III of the MDS-UPDRS, was zero among the dancers (slope = 0.000146), indicating no motor impairment, whereas among the nondancers, the motor decline during follow-up was as expected (P < .01), the researchers reported.

In modeling the data, the researchers determined that after completing 1,000 days of dance training, dancers will have a motor score of 19.07, compared with a score of 28.27 for nondancers.

“Our data further showed that training in dance will slow the rate of PD motor impairment progression, as measured by the UPDRS III, by close to 3 points annually in comparison to our PD subjects who did not train,” the researchers reported.

Dance training also had a beneficial effect on motor or nonmotor aspects of daily living and on motor complications, for which there was no significant decline among the PD dancers.

“For those with Parkinson’s disease, even when it’s mild, motor impairment can impact their daily functioning – how they feel about themselves. Many of these motor symptoms lead to isolation because once they get extreme, these people don’t want to go out,” Dr. DeSouza said in a news release.

“These motor symptoms lead to further psychological issues, depression, social isolation and eventually the symptoms do get worse over time. Our study shows that training with dance and music can slow this down and improve their daily living and daily function,” he added.
 

‘Great potential’

Reached for comment, Demian Kogutek, PhD, director of music therapy, University of Evansville (Indiana), said that these preliminary findings from a longitudinal study are “promising.”

“I believe that dance therapy has a great potential for PD. The longitudinal aspect of this study undoubtedly adds to the current literature. Although it is a standardized assessment, it is somewhat subjective,” Dr. Kogutek said in an interview.

Going forward, Dr. Kogutek said he’d like to see other objective outcomes measured, such as objective assessments of balance, gait, hand strength, and dexterity.

Also weighing in on the results, Karen Lee, PhD, president and CEO of Parkinson Canada, said her organization is “encouraged by these preliminary findings as exercise and healthy activities are important for people with Parkinson’s. This study is part of a growing body of research that explores the link between the impact of activities and both motor and nonmotor symptoms of Parkinson’s.

“This research adds to growing evidence about the importance of exercise as part of the management of Parkinson’s, and we encourage people living with Parkinson’s to incorporate exercise as part of their approach to managing their health,” Dr. Lee said in an interview.

Dancing helps slow the progression of motor and nonmotor symptoms and improves quality of life for patients with Parkinson’s disease (PD), new research shows.

Over 3 years, weekly participation in dance training classes “drastically” reduced the expected decline in motor function and significantly improved speech, tremors, balance, and stiffness, the researchers reported.

Dance training also appeared to have benefits regarding cognition, hallucinations, depression, and anxiety.

“These findings strongly suggest the benefits of dance for people with PD as a supplement to a normal treatment regimen,” the investigators noted.

Although the mechanism of benefit is unclear, dance training may help “train neural network nodes that helps either strengthen networks damaged or builds neural road maps that pass the damage,” study investigator Joseph DeSouza, PhD, principal investigator and associate professor, department of psychology, York University, Toronto, said in an interview.

The study was published online July 7, 2021, in Brain Sciences.
 

Multiple benefits

PD is a neurodegenerative disease associated with progression of motor dysfunction within the first 5 years of diagnosis. The annual rate of motor decline, as determined with the Movement Disorder Society Unified Parkinson’s Disease Rating Scale (MDS-UPDRS), is between 5.2 and 8.9 points.

Prior studies that assessed various styles of dance by patients with PD showed beneficial effects regarding gait speed, balance, locomotion, and aspects of quality of life.

To investigate further, DeSouza and coauthor Karolina Bearss, a PhD candidate at York University, followed 16 patients with mild to moderate PD who participated in a weekly dance class at Canada’s National Ballet School and Trinity St. Paul’s church.

Dance for Parkinson’s Disease, which is an established dance curriculum, involves aerobic and anaerobic movements. The protocol begins with a seated warm-up, followed by barre work, and ends with moving across the floor. All participants learn choreography for an upcoming performance.

In the study, 16 patients with PD who did not participant in the dance classes served as control patients.

Over 3 years, the daily rate of motor decline, as indicated by scores on part III of the MDS-UPDRS, was zero among the dancers (slope = 0.000146), indicating no motor impairment, whereas among the nondancers, the motor decline during follow-up was as expected (P < .01), the researchers reported.

In modeling the data, the researchers determined that after completing 1,000 days of dance training, dancers will have a motor score of 19.07, compared with a score of 28.27 for nondancers.

“Our data further showed that training in dance will slow the rate of PD motor impairment progression, as measured by the UPDRS III, by close to 3 points annually in comparison to our PD subjects who did not train,” the researchers reported.

Dance training also had a beneficial effect on motor or nonmotor aspects of daily living and on motor complications, for which there was no significant decline among the PD dancers.

“For those with Parkinson’s disease, even when it’s mild, motor impairment can impact their daily functioning – how they feel about themselves. Many of these motor symptoms lead to isolation because once they get extreme, these people don’t want to go out,” Dr. DeSouza said in a news release.

“These motor symptoms lead to further psychological issues, depression, social isolation and eventually the symptoms do get worse over time. Our study shows that training with dance and music can slow this down and improve their daily living and daily function,” he added.
 

‘Great potential’

Reached for comment, Demian Kogutek, PhD, director of music therapy, University of Evansville (Indiana), said that these preliminary findings from a longitudinal study are “promising.”

“I believe that dance therapy has a great potential for PD. The longitudinal aspect of this study undoubtedly adds to the current literature. Although it is a standardized assessment, it is somewhat subjective,” Dr. Kogutek said in an interview.

Going forward, Dr. Kogutek said he’d like to see other objective outcomes measured, such as objective assessments of balance, gait, hand strength, and dexterity.

Also weighing in on the results, Karen Lee, PhD, president and CEO of Parkinson Canada, said her organization is “encouraged by these preliminary findings as exercise and healthy activities are important for people with Parkinson’s. This study is part of a growing body of research that explores the link between the impact of activities and both motor and nonmotor symptoms of Parkinson’s.

“This research adds to growing evidence about the importance of exercise as part of the management of Parkinson’s, and we encourage people living with Parkinson’s to incorporate exercise as part of their approach to managing their health,” Dr. Lee said in an interview.
