The FDA authorized a new type of saliva-based coronavirus test on August 15 that could cut down on the cost of testing and the time it takes to process results.

The emergency use authorization is for SalivaDirect, a diagnostic test created by the Yale School of Public Health. The test doesn’t require a special type of swab or collection tube — saliva can be collected in any sterile container, according to the FDA announcement.

The new test is “yet another testing innovation game changer that will reduce the demand for scarce testing resources,” Admiral Brett Giroir, MD, the assistant secretary for health and the COVID-19 testing coordinator, said in the statement.

The test also doesn’t require a special type of extractor, which is helpful because the extraction kits used to process other tests have faced shortages during the pandemic. The test can be used with different types of reagents and instruments already found in labs.

“Providing this type of flexibility for processing saliva samples to test for COVID-19 infection is groundbreaking in terms of efficiency and avoiding shortages of crucial test components like reagents,” Stephen Hahn, MD, the FDA commissioner, also said in the statement.

Yale will provide the instructions to labs as an “open source” protocol. The test doesn’t require any proprietary equipment or testing components, so labs across the country can assemble and use it based on the FDA guidelines. The testing method is available immediately and could be scaled up quickly in the next few weeks, according to a statement from Yale.

“This is a huge step forward to make testing more accessible,” Chantal Vogels, a postdoctoral fellow at Yale who led the lab development and test validation efforts, said in the statement.

The Yale team is further testing whether the saliva method can be used to find coronavirus cases among people who don’t have any symptoms and has been working with players and staff from the NBA. So far, the results have been accurate and similar to the nasal swabs for COVID-19, according to a preprint study published on medRxiv.

The research team wanted to get rid of the expensive collection tubes that other companies use to preserve the virus during processing, according to the Yale statement. They found that the virus is stable in saliva for long periods of time at warm temperatures and that special tubes aren’t necessary.

The FDA has authorized other saliva-based tests, according to ABC News, but SalivaDirect is the first that doesn’t require the extraction process used to test viral genetic material. Instead, the Yale process breaks down the saliva with an enzyme and applied heat. This type of testing could cost about $10, the Yale researchers said, and people can collect the saliva themselves under supervision.

“This, I hope, is a turning point,” Anne Wyllie, PhD, one of the lead researchers at Yale, told the news station.* “Expand testing capacity, inspire creativity and we can take competition to those labs charging a lot and bring prices down.”

During the pandemic, physicians have raced to set up or expand telemedicine, uncovering both advantages and shortcomings. Now experts have developed a checklist of more than a dozen ideas to facilitate effective virtual visits with older adults.

Although many of the suggestions, published online in Annals of Internal Medicine, are useful for all patients, Carrie Nieman, MD, MPH, and Esther S. Oh, MD, PhD, developed the list with older patients in mind.

“I have a number of patients into their 90s and with hearing loss, and we have had very successful video-based telemedicine visits,” Dr. Nieman, with the Cochlear Center for Hearing and Public Health at Johns Hopkins Bloomberg School of Public Health in Baltimore said in an interview. “Age should not be considered synonymous with inability or unwillingness to use technology.”

Their recommendations included the following:

• Assume some degree of hearing loss, which affects about two-thirds of adults aged 70 years and older.
• Ask patients to wear headphones or a headset or confirm that they are wearing their hearing aids and are in a quiet location.
• Use a headset.
• When possible, use video and have the camera focused on your face.
• Use captioning when available and provide a written summary of key points and instructions.
• Pay attention to cues, such as nodding along or looking to a loved one, that suggest a patient may not be following the conversation.

“If cognitive impairment is suspected, several screening tools can be used over the telephone to identify individuals who may need more comprehensive, in-person assessment,” wrote Dr. Nieman and Dr. Oh, who is with the division of geriatric medicine and gerontology at Johns Hopkins University School of Medicine. For example, data suggest that a modified version of the Mini–Mental State Examination and the Delirium Symptom Interview could be useful tools. “A formal diagnosis of dementia is not recommended solely based on a telephone-based cognitive screening,” however, Dr. Nieman and Dr. Oh said.

For patients with hearing loss, video visits avoid a current limitation of in-person visits: face masks that hinder patients’ ability to read lips and other visual cues. “For many of us, we rely on these types of cues more than we think,” Dr. Nieman said in an interview.

“When you have doubts about whether you and your patient are on the same page, check in with the patient,” Dr. Nieman said. “When appropriate, having a loved one or a care partner join an encounter, or at least a portion of the encounter, can be helpful to both the patient and the provider.”

Many older patients unprepared

Millions of older patients may not have been ready for the rapid shift to telemedicine brought on by COVID-19, a recent study in JAMA Internal Medicine suggests. Between 32% and 38% of older adults in the United States may not have been ready for video visits, largely because of inexperience with technology. Approximately 20% could have difficulty with telephone visits because of problems hearing or communicating or because of dementia.

Kenneth Lam, MD, of the division of geriatrics at the University of California, San Francisco (UCSF), and colleagues arrived at these estimates after analyzing data from more than 4,500 participants in the National Health and Aging Trends Study that was conducted in 2018. The study is nationally representative of Medicare beneficiaries 65 years or older.

The aim of the study “was to call attention to what clinicians were already experiencing on the front lines,” Dr. Lam said. In an interview, he imagined two scenarios based on his colleagues’ accounts of telemedicine visits.

In one case, a 72-year-old woman logs into Zoom Health on her iPad without any trouble. “She explains she just pushed on the URL and everything loaded up and you have a great visit,” Dr. Lam said. “This is likely to be the case for over 50% of the older people you see; I share this picture to combat ageism, which is, truthfully, just inaccurate stereotyping of older people and gets in the way of actionable, data-driven policies.

“However, for around one in three older adults (and closer to three out of every four of those over the age of 85), you will book an appointment and they will say they don’t have an email address or a computer or know how to go online,” Dr. Lam said. “Or suppose they decide to try it out. ... Come appointment time, you log on and they pick up, but now their sound doesn’t work. They keep saying they can see you but they can’t hear you. ... They accidentally hang up. You place another call, and they ask if you can switch to a phone conversation instead.”

By phone, the physician can address concerns about the patient’s blood pressure, which the patient has been measuring daily. “But when it comes to looking at the swelling in their legs, you’re out of luck, and you’ve been on this call for 45 minutes,” Dr. Lam said.

Have a backup plan

Making sure patients are prepared and having a backup plan can help, said Kaitlin Willham, MD, of UCSF and the San Francisco VA Medical Center.

She says older patients fall into a wide range of categories in terms of skills and access to equipment. Knowing which category a patient falls into and having relevant support available to troubleshoot are important.

During the pandemic, Dr. Willham has conducted many more telemedicine visits with patients who are at their place of residence, whether a private home or a residential care facility. “Even outside of the current crisis, there are benefits to home video visits,” Dr. Willham said. “A home video visit can provide a more holistic view of the patient than an office visit, allowing the clinician to see how the person lives, what they might be challenged by. It allows the clinician to identify areas of intervention and, if there is a care partner, involving that person in the plan. If the visit starts without major technical or communication barriers, they are generally very well received.”

For patients with problems hearing for whom headphones or amplification devices are not available, “using a landline for the audio portion of the visit can help, as can having someone with the patient reiterate what was said,” Dr. Willham suggested. “Many video platforms also enable the clinician to type messages or share a screen with a live document. These options can work well when there is very severe or complete lack of hearing.”

Sometimes an in-person visit is the right way to go, even when technical hurdles can be overcome.

“Although many older adults are willing and able to learn to use telemedicine, an equitable health system should recognize that for some, such as those with dementia and social isolation, in-person visits are already difficult and telemedicine may be impossible,” Dr. Lam and coauthors wrote. “For these patients, clinics and geriatric models of care such as home visits are essential.”

Dr. Nieman, Dr. Oh, and one of Dr. Lam’s coauthors have received funding from the National Institutes of Health. Dr. Oh also has received funding from the Roberts Family Fund. Dr. Nieman serves as a board member of the nonprofit organization Access HEARS and is on the board of trustees of the Hearing Loss Association of America.

Research on COVID-19 as it relates to rheumatic and musculoskeletal diseases (RMDs) is accumulating “at an enormously rapid pace,” but a recent review of the literature suggests that quantity should not be confused with quality.

“We are faced by the worldwide spread of a disease that was nonexistent less than a year ago,” Féline P.B. Kroon, MD, and associates said in Annals of the Rheumatic Diseases. “To date, no robust evidence is available to allow strong conclusions on the effects of COVID-19 in patients with RMDs or whether RMDs or [their] treatment impact incidence of infection or outcomes.”

When it comes to quantity of evidence, “the exponential increase in publications over time is evident,” they said. From Jan. 1, 2019 to June 24, 2020, there were 1,725 hits on PubMed for published reports combining COVID-19 with RMDs and drugs used in RMDs. At the beginning of the year, there were only 135 such publications.

The early start of the search, well before identification of the novel coronavirus in China, was meant to ensure that nothing was missed, so “citations that came up in the first months of 2019 mostly encompass papers about other coronaviruses, such as SARS and MERS,” said Dr. Kroon of Zuyderland Medical Center, Heerlen, the Netherlands, when asked for clarification.

The quality of that evidence, however, is another matter. A majority of publications (60%) are “viewpoints or (narrative) literature reviews, and only a small proportion actually presents original data in the form of case reports or case series (15%), observational cohort studies (10%), or clinical trials (<1%),” the investigators explained.

Very few of the published studies, about 10%, specifically involve COVID-19 and RMDs. Even well-regarded sources such as systematic literature reviews or meta-analyses, “which will undoubtedly appear more frequently in the next few months in response to requests by users who feel overwhelmed by a multitude of data, will not eliminate the internal bias present in individual studies,” Dr. Kroon and associates wrote.

The lack of evidence also brings into question one particular form of guidance: recommendations “issued by groups of the so-called experts and (inter)national societies, such as, among others, American College of Rheumatology and European League Against Rheumatism,” the investigators said.

“The rapid increase in research on COVID-19 is encouraging,” but at the same time it “also poses risks of ‘information overload’ or ‘fake news,’ ” they said. “As researchers and clinicians, it is our responsibility to carefully interpret study results that emerge, even more so in this ‘digital era,’ in which published data can quickly have a large societal impact.”

Research on COVID-19 as it relates to rheumatic and musculoskeletal diseases (RMDs) is accumulating “at an enormously rapid pace,” but a recent review of the literature suggests that quantity should not be confused with quality.

“We are faced by the worldwide spread of a disease that was nonexistent less than a year ago,” Féline P.B. Kroon, MD, and associates said in Annals of the Rheumatic Diseases. “To date, no robust evidence is available to allow strong conclusions on the effects of COVID-19 in patients with RMDs or whether RMDs or [their] treatment impact incidence of infection or outcomes.”

When it comes to quantity of evidence, “the exponential increase in publications over time is evident,” they said. From Jan. 1, 2019 to June 24, 2020, there were 1,725 hits on PubMed for published reports combining COVID-19 with RMDs and drugs used in RMDs. At the beginning of the year, there were only 135 such publications.

The early start of the search, well before identification of the novel coronavirus in China, was meant to ensure that nothing was missed, so “citations that came up in the first months of 2019 mostly encompass papers about other coronaviruses, such as SARS and MERS,” said Dr. Kroon of Zuyderland Medical Center, Heerlen, the Netherlands, when asked for clarification.

The quality of that evidence, however, is another matter. A majority of publications (60%) are “viewpoints or (narrative) literature reviews, and only a small proportion actually presents original data in the form of case reports or case series (15%), observational cohort studies (10%), or clinical trials (<1%),” the investigators explained.

Very few of the published studies, about 10%, specifically involve COVID-19 and RMDs. Even well-regarded sources such as systematic literature reviews or meta-analyses, “which will undoubtedly appear more frequently in the next few months in response to requests by users who feel overwhelmed by a multitude of data, will not eliminate the internal bias present in individual studies,” Dr. Kroon and associates wrote.

The lack of evidence also brings into question one particular form of guidance: recommendations “issued by groups of the so-called experts and (inter)national societies, such as, among others, American College of Rheumatology and European League Against Rheumatism,” the investigators said.

“The rapid increase in research on COVID-19 is encouraging,” but at the same time it “also poses risks of ‘information overload’ or ‘fake news,’ ” they said. “As researchers and clinicians, it is our responsibility to carefully interpret study results that emerge, even more so in this ‘digital era,’ in which published data can quickly have a large societal impact.”

Combining specimens from several low-risk inpatients in a single test for SARS-CoV-2 infection allowed hospital staff to stretch testing supplies and provide test results quickly for many more patients than they might have otherwise, researchers found.

“We believe this strategy conserved [personal protective equipment (PPE)], led to a marked reduction in staff and patient anxiety, and improved patient care,” wrote David Mastrianni, MD, and colleagues from Saratoga Hospital in Saratoga Springs, N.Y. “Our impression is that testing all admitted patients has also been reassuring to our community.”

The researchers published their findings July 20 in the Journal of Hospital Medicine.

“What was really important about this study was they were actually able to implement pooled testing after communication with the [Food and Drug Administration],” Samir S. Shah, MD, MSCE, SFHM, the journal’s editor-in-chief, said in an interview.

“Pooled testing combines samples from multiple people within a single test. The benefit is, if the test is negative [you know that] everyone whose sample was combined … is negative. So you’ve effectively tested anywhere from three to five people with the resources required for only one test,” Dr. Shah continued.

The challenge is that, if the test is positive, everyone in that testing group must be retested individually because one or more of them has the infection, said Dr. Shah, director of hospital medicine at Cincinnati Children’s Hospital Medical Center.

Dr. Mastrianni said early in the pandemic they started getting the “New York surge” at their hospital, located approximately 3 hours from New York City. They wanted to test all of the inpatients at their hospital for COVID-19 and they had a rapid in-house test that worked well, “but we just didn’t have enough cartridges, and we couldn’t get deliveries, and we started pooling.” In fact, they ran out of testing supplies at one point during the study but were able to replenish their supply in about a day, he noted.

For the current study, all patients admitted to the hospital, including those admitted for observation, underwent testing for SARS-CoV-2. Staff in the emergency department designated patients as low risk if they had no symptoms or other clinical evidence of COVID-19; those patients underwent pooled testing.

Patients with clinical evidence of COVID-19, such as respiratory symptoms or laboratory or radiographic findings consistent with infection, were considered high risk and were tested on an individual basis and thus excluded from the current analysis.

The pooled testing strategy required some patients to be held in the emergency department until there were three available for pooled testing. On several occasions when this was not practical, specimens from two patients were pooled.

Between April 17 and May 11, clinicians tested 530 patients via pooled testing using 179 cartridges (172 with swabs from three patients and 7 with swabs from two patients). There were four positive pooled tests, which necessitated the use of an additional 11 cartridges. Overall, the testing used 190 cartridges, which is 340 fewer than would have been used if all patients had been tested individually. 

Among the low-risk patients, the positive rate was 0.8% (4/530). No patients from pools that were negative tested positive later during their hospitalization or developed evidence of the infection.
 

Team effort, flexibility needed

Dr. Mastrianni said he expected their study to find that pooled testing saved testing resources, but he “was surprised by the complexity of the logistics in the hospital, and how it really required getting everybody to work together. …There were a lot of details, and it really took a lot of teamwork.”

The nursing supervisor in the emergency department was in charge of the batch and coordinated with the laboratory, he explained. There were many moving parts to manage, including monitoring how many patients were being admitted, what their conditions were, whether they were high or low risk, and where they would house those patients as the emergency department became increasingly busy. “It’s a lot for them, but they’ve adapted really well,” Dr. Mastrianni said.

Pooling tests seems to work best for three to five patients at a time; larger batches increase the chance of having a positive test, and thus identifying the sick individual(s) becomes more challenging and expensive, Dr. Shah said.

“It’s a fine line between having a pool large enough that you save on testing supplies and testing costs but not having the pool so large that you dramatically increase your likelihood of having a positive test,” Dr. Shah said.

Hospitals will likely need to be flexible and adapt as the local positivity rate changes and supply levels vary, according to the authors.

“Pooled testing is mainly dependent on the COVID-19 positive rate in the population of interest in addition to the sensitivity of the [reverse transcriptase-polymerase chain reaction (RT-PCR)] method used for COVID-19 testing,” said Baha Abdalhamid, MD, PhD, of the department of pathology and microbiology at the University of Nebraska Medical Center in Omaha.

“Each laboratory and hospital needs to do their own validation testing because it is dependent on the positive rate of COVID-19,” added Dr. Abdalhamid, who was not involved in the current study.

It’s important for clinicians to “do a good history to find who’s high risk and who’s low risk,” Dr. Mastrianni said. Clinicians also need to remember that, although a patient may test negative initially, they may still have COVID-19, he warned. That test reflects a single point in time, and a patient could be infected and not yet be ill, so clinicians need to be alert to a change in the patient’s status.
 

Best for settings with low-risk individuals

“Pooled COVID-19 testing is a straightforward, cost-effective, and efficient approach,” Dr. Abdalhamid said. He and his colleagues found pooled testing could increase testing capability by 69% or more when the incidence rate of SARS-CoV-2 infection is 10% or lower.

He said the approach would be helpful in other settings “as long as the positive rate is equal to or less than 10%. Asymptomatic population or surveillance groups such as students, athletes, and military service members are [an] interesting population to test using pooling testing because we expect these populations to have low positive rates, which makes pooled testing ideal.” 
 

Benefit outweighs risk

“There is risk of missing specimens with low concentration of the virus,” Dr. Abdalhamid cautioned. “These specimens might be missed due to the dilution factor of pooling [false-negative specimens]. We did not have a single false-negative specimen in our proof-of-concept study. In addition, there are practical approaches to deal with false-negative pooled specimens.

“The benefit definitely outweighs the risk of false-negative specimens because false-negative results rarely occur, if any. In addition, there is significant saving of time, reagents, and supplies in [a] pooled specimens approach as well as expansion of the test for higher number of patients,” Dr. Abdalhamid continued. 

Dr. Mastrianni’s hospital currently has enough testing cartridges, but they are continuing to conduct pooled testing to conserve resources for the benefit of their own hospital and for the nation as a whole, he said.

Let us begin with a thought exercise. Close your eyes and picture the word, “hero.” What comes to mind? A relative, a teacher, a fictional character wielding a hammer or flying gracefully through the air?

Several months ago, our country was introduced to a foe that brought us to our knees. Before that time, the idea of a hero had fluctuated with circumstance and had been guided by aging and maturity; however, since the moment COVID-19 struck, a new image has emerged. Not all heroes wear capes, but some wield stethoscopes.

Over these past months the phrase, “Health Care Heroes” has spread throughout our collective consciousness, highlighted everywhere from talk shows and news media to billboards and journals. Doctors, nurses, and other health care professionals are lauded for their strength, dedication, resilience, and compassion. Citizens line up to clap, honk horns, and shower praise in recognition of those who have risked their health, sacrificed their personal lives, and committed themselves to the greater good. Yet, what does it mean to be a hero, and what is the cost of hero worship?

The focus of medical training has gradually shifted to include the physical as well as mental well-being of future physicians, but the remnants of traditional doctrine linger. Hours of focused training through study and direct clinical interaction reinforce dedication to patient care. Rewards are given for time spent and compassion lent, and research is lauded, but family time is rarely applauded. We are encouraged to do our greatest, work our hardest, be the best, rise and defeat every test. Failure (or the perception thereof) is not an option.

According to Rikinkumar S. Patel, MD, MPH, and associates, physicians have nearly twice the burnout rate of other professionals (Behav Sci. [Basel]. 2018 Nov;8[11]:98). The dedication to our craft propels excellence as well as sacrifice. When COVID-19 entered our lives, many of my colleagues did not hesitate to heed to the call for action. They immersed themselves in the ICU, led triage units, and extended work hours in the service of the sick and dying. Several were years removed from emergency/intensive care, while others were allocated from their chosen residency programs and voluntarily thrust into an environment they had never before traversed.

These individuals are praised as “brave,” “dedicated,” “selfless.” A few even provided insight into their experiences through various publications highlighting their appreciation and gratitude toward such a treacherous, albeit, tremendous experience. Even though their words are an honest perspective of life through one of the worst health care crises in 100 years, in effect, they perpetuate the noble hero; the myth of the super doctor.

In a profession that has borne witness to multiple suicides over the past few months, why do we not encourage open dialogue of our victories as well as our defeats? Our wins as much as our losses? Why does an esteemed veteran physician feel guilt over declining to provide emergency services to patients whom they have long forgotten how to manage? What drives the guilt and the self-doubt? Are we ashamed of what others will think? Is it that the fear of not living up to our cherished medical oath outweighs our own boundaries and acknowledgment of our limitations?

A hero is an entity, a person encompassing a state of being, yet health care professionals are bestowed this title and this burden on a near-daily basis. Physicians are people. We love, we fear, we hesitate, we fight, we deem to overcome. We are perfectly imperfect. The more in tune we are to vulnerability, the more honest we can become with ourselves and one another.

Are we ashamed of what others will think? Is it that the fear of not living up to our cherished medical oath outweighs our own boundaries and acknowledgment of our limitations?

A hero is an entity, a person encompassing a state of being, yet health care professionals are bestowed this title and this burden on a near-daily basis. Physicians are people. We love, we fear, we hesitate, we fight, we deem to overcome. We are perfectly imperfect. The more in tune we are to vulnerability, the more honest we can become with ourselves and one another.

Accumulating observational data suggest that metformin use in patients with type 2 diabetes might reduce the risk for death from COVID-19, but the randomized trials needed to prove this are unlikely to be carried out, according to experts.

The latest results, which are not yet peer reviewed, were published online July 31. The study was conducted by Andrew B. Crouse, PhD, of the Hugh Kaul Precision Medicine Institute, University of Alabama at Birmingham, and colleagues.

The researchers found that among more than 600 patients with diabetes and COVID-19, use of metformin was associated with a nearly 70% reduction in mortality after adjustment for multiple confounders.

Data from four previous studies that also show a reduction in mortality among metformin users compared to nonusers were summarized in a “mini review” by André J. Scheen, MD, PhD, published Aug. 1 in Diabetes and Metabolism.

Dr. Scheen, of the division of diabetes, nutrition, and metabolic disorders and the division of clinical pharmacology at Liège (Belgium) University, discussed possible mechanisms behind this observation.

“Because metformin exerts various effects beyond its glucose-lowering action, among which are anti-inflammatory effects, it may be speculated that this biguanide might positively influence the prognosis of patients with [type 2 diabetes] hospitalized for COVID-19,” he said.

“However, given the potential confounders inherently found in observational studies, caution is required before drawing any firm conclusions in the absence of randomized controlled trials,” Dr. Scheen wrote.

Indeed, when asked to comment, endocrinologist Kasia Lipska, MD, of Yale University, New Haven, Conn., said in an interview: “Metformin users tend to do better in many different settings with respect to many different outcomes. To me, it is still unclear whether metformin is truly a miracle drug or whether it is simply used more often among people who are healthier and who do not have contraindications to its use.”

She added, “I don’t think we have enough data to suggest metformin use for COVID-19 mitigation at this point.”

Alabama authors say confounding effects ‘unlikely’

In the retrospective analysis of electronic health records from their institution, Dr. Crouse and colleagues reviewed data from 604 patients who were confirmed to have tested positive for COVID-19 between Feb. 25 and June 22, 2020. Of those individuals, 40% had diabetes.

Death occurred in 11% (n = 67); the odds ratio (OR) for death among those with, vs. without, diabetes was 3.62 (P < .0001).

Individuals with diabetes accounted for >60% of all deaths. In multiple logistic regression, age 50-70 vs. <50, male sex, and diabetes emerged as independent predictors of death.

Of the 42 patients with diabetes who died, 8 (19%) had used metformin, and 34 (81%) had not*, a significant difference (OR, 0.38; P = .0221). Insulin use, on the other hand, had no effect on mortality (P = .5728).

“In fact, with 11% [being] the mortality of metformin users, [this] was comparable to that of the general COVID-19-positive population and dramatically lower than the 23% mortality observed in subjects with diabetes and not on metformin,” the authors said.

The survival benefit observed with metformin remained after exclusion of patients with classic metformin contraindications, such as chronic kidney disease and heart failure (OR, 0.17; P = .0231).

“This makes any potential confounding effects from skewing metformin users toward healthier subjects without these additional comorbidities very unlikely,” Dr. Crouse and colleagues contended.

After further analysis that controlled for other covariates (age, sex, obesity status, and hypertension), age, sex, and metformin use remained independent predictors of mortality.

For metformin, the odds ratio was 0.33 (P = .0210).

But, Dr. Lipska pointed out, “Observational studies can take into account confounders that are measured. However, unmeasured confounders may still affect the conclusions of these studies ... Propensity score matching to account for the likelihood of use of metformin could be used to better account for differences between metformin users and nonusers.”

If metformin does reduce COVID-19 deaths, multiple mechanisms likely

In his article, Dr. Scheen noted that several mechanisms have been proposed for the possible beneficial effect of metformin on COVID-19 outcomes, including direct improvements in glucose control, body weight, and insulin resistance; reduction in inflammation; inhibition of virus penetration via phosphorylation of ACE2; inhibition of an immune hyperactivation pathway; and neutrophil reduction. All remain theoretical, he emphasized.

He noted that some authors have raised concerns about possible harms from the use of metformin by patients with type 2 diabetes who are hospitalized for COVID-19, particularly because of the potential risk for lactic acidosis in cases of multiple organ failure.

In totality, four studies suggest 25% death reduction with metformin

Taken together, the four observational studies that Dr. Scheen reviewed showed that metformin had a positive effect, with an overall 25% reduction in death (P < .00001), albeit with relatively high heterogeneity (I² = 61%).

The largest of these, from the United States, included 6,256 patients hospitalized with COVID-19 and involved propensity matching. A significant reduction in mortality with metformin use was seen in women but not men (odds ratio, 0.759).

The French Coronavirus-SARS-CoV-2 and Diabetes Outcomes (CORONADO) study of 1,317 patients with diabetes and confirmed COVID-19 who were admitted to 53 French hospitals also showed a significant survival benefit for metformin, although the study wasn’t designed to address that issue.

In that study, the odds ratio for death on day 7 in prior metformin users compared to nonusers was 0.59. This finding lost significance but remained a trend after full adjustments (0.80).

Two smaller observational studies produced similar trends toward survival benefit with metformin.

Nonetheless, Dr. Scheen cautioned: “Firm conclusions about the impact of metformin therapy can only be drawn from double-blind randomized controlled trials (RCTs), and such trials are almost impossible in the context of COVID-19.”

He added: “Because metformin is out of patent and very inexpensive, no pharmaceutical company is likely to be interested in planning a study to demonstrate the benefits of metformin on COVID-19-related clinical outcomes.”

Dr. Lipska agreed: “RCTs are unlikely to be conducted to settle these issues. In their absence, metformin use should be based on its safety and effectiveness profile.”

Dr. Scheen concluded, however, that “there are at least no negative safety indications, so there is no reason to stop metformin therapy during COVID-19 infection except in cases of severe gastrointestinal symptoms, hypoxia and/or multiple organ failure.”

Dr. Lipska has received grants from the National Institutes of Health and works under contract for the Centers for Medicare & Medicaid Services to develop publicly reported quality measures. Dr. Scheen has disclosed no relevant financial relationships.

As mask mandates have increased, some people are looking for a way around the rules by asking doctors for medical excuses to opt out of wearing one.

filadendron/E+

In the last 2 months, at least 10 patients have asked Constantine George, MD, for a written medical exemption so they won’t have to wear a mask in public. Dr. George, the chief medical officer of Vedius, an app for a travelers’ concierge medical service in Las Vegas, turned them all down.

Elena Christofides, MD, an endocrinologist in Columbus, Ohio, has also refused patients’ requests for exemptions.

“It’s very rare for someone to need an exemption,” says Albert Rizzo, MD, chief medical officer for the American Lung Association and a lung specialist at ChristianaCare Health System in Newark, Del.

The opposition is sometimes strong. Recently, a video of Lenka Koloma of Laguna Niguel, Calif., who founded the antimask Freedom to Breathe Agency, went viral. She was in a California supermarket, maskless, telling an employee she was breaking the law by requiring patrons to wear masks.

“People need oxygen,” she said. “That alone is a medical condition.” Her webpage has a “Face Mask Exempt Card” that cites the Americans with Disabilities Act and posts a Department of Justice ADA violation reporting number. The DOJ issued a statement calling the cards fraudulent.

Figuring out if a patient’s request to opt out of wearing a mask is legitimate is a ‘’new frontier” for doctors, says Mical Raz, MD, a professor in public policy and health at the University of Rochester (N.Y.), and a hospitalist at the university medical center.
 

Should some people skip masks?

Experts say there are very few medical reasons for people to skip masks. “If you look at the research, patients with COPD [chronic obstructive pulmonary disorder], those with reactive airway, even those can breathe through a mask,” Dr. George said. Requests for exemptions due to medical reasons are usually without basis. “Obviously, if someone is incapacitated, for example, with mental health issues, that’s case by case.”

Dr. Christofides said one of her patients cited anxiety and the other cited headaches as reasons not to wear a mask. “I told the one who asked for anxiety [reasons] that she could wear ones that were less tight.” The patient with headaches told Dr. Christofides that she had a buildup of carbon dioxide in the mask because of industrial exposure. Baloney, Dr. Christofides told her.

Dr. Rizzo says one rare example of someone who can’t wear a mask might be a patient with an advanced lung condition so severe, they need extra oxygen. “These are the extreme patients where any change in oxygen and carbon dioxide could make a difference,” he said. But “that’s also the population that shouldn’t be going out in the first place.”

Dr. Raz cowrote a commentary about mask exemptions, saying doctors are faced with difficult decisions and must keep a delicate balance between public health and individual disability needs. “Inappropriate medical exemptions may inadvertently hasten viral spread and threaten public health,” she wrote.

In an interview, she says that some people do have a hard time tolerating a mask. “Probably the most common reasons are mental health issues, such as anxiety, panic and PTSD, and children with sensory processing disorders (making them oversensitive to their environment). I think there are very few pulmonary reasons.”
 

CDC, professional organization guidelines

The CDC says people should wear masks in public and when around people who don’t live in the same household. Beyond that, it simply says masks should not be worn by children under age 2, “or anyone who has trouble breathing, is unconscious, incapacitated, or otherwise unable to remove the mask without assistance.”

In mid-July, four professional organizations released a statement in response to the CDC recommendation for facial coverings. Jointly issued by the American College of Chest Physicians, the American Lung Association, the American Thoracic Society and the COPD Foundation, it states in part that people with normal lungs and “even many individuals with underlying chronic lung disease should be able to wear a non-N95 facial covering without affecting their oxygen or carbon dioxide levels.”

It acknowledges that some people will seek an exemption and doctors must weigh the patient’s concerns against the need to stop the spread of the virus. “In some instances, physician reassurance regarding the safety of the facial coverings may be all that is needed,” it states.
 

Addressing the excuses

Here are some of the common medical reasons people give for not being able to tolerate a mask:

Claustrophobia or anxiety. Dr. Raz and others suggests a “desensitizing” period, wearing the mask for longer and longer periods of time to get used to it. Parents could suggest kids wear a mask when doing something they like, such as watching television, so they equate it with something pleasant. Switching to a different kind of mask or one that fits better could also help.

Masks cause Legionnaires’ disease. Not true, experts say. Legionnaires’ is a severe form of pneumonia, the result of inhaling tiny water droplets with legionella bacteria.

It’s difficult to read lips. People can buy masks with a clear window that makes their mouth and lips visible.

Trouble breathing. Brief periods of mask use won’t have a bad effect on oxygen levels for most people.

“There is not an inherent right to be out in a pandemic with an unmasked face,” Dr. Raz says. But “you are entitled to an accommodation.” That might be using curbside pickup for food and medication. That requires much less time wearing a mask than entering a store would.

There are no “boilerplate” cards or letters to excuse people provided by the four organizations that addressed the issue, Dr. Rizzo said. If he were to write a letter asking for an exemption, he would personalize it for an individual patient’s medical condition. As to whether a state would honor it, he cannot say. The states have a patchwork of recommendations, making it difficult to say.

Dr. Rizzo tells lung disease patients who are able to go out that wearing a mask for 15-20 minutes to do an errand won’t harm their oxygen levels. And he reminds them that having an exemption, in the form of a doctor’s letter, may bring more problems. “Even with an exemption, someone may confront them” for their lack of a face covering. People with COPD have a higher risk of getting a severe illness from COVID-19, according to the CDC.

As mask mandates have increased, some people are looking for a way around the rules by asking doctors for medical excuses to opt out of wearing one.

In the last 2 months, at least 10 patients have asked Constantine George, MD, for a written medical exemption so they won’t have to wear a mask in public. Dr. George, the chief medical officer of Vedius, an app for a travelers’ concierge medical service in Las Vegas, turned them all down.

Elena Christofides, MD, an endocrinologist in Columbus, Ohio, has also refused patients’ requests for exemptions.

“It’s very rare for someone to need an exemption,” says Albert Rizzo, MD, chief medical officer for the American Lung Association and a lung specialist at ChristianaCare Health System in Newark, Del.

The opposition is sometimes strong. Recently, a video of Lenka Koloma of Laguna Niguel, Calif., who founded the antimask Freedom to Breathe Agency, went viral. She was in a California supermarket, maskless, telling an employee she was breaking the law by requiring patrons to wear masks.

“People need oxygen,” she said. “That alone is a medical condition.” Her webpage has a “Face Mask Exempt Card” that cites the Americans with Disabilities Act and posts a Department of Justice ADA violation reporting number. The DOJ issued a statement calling the cards fraudulent.

Figuring out if a patient’s request to opt out of wearing a mask is legitimate is a ‘’new frontier” for doctors, says Mical Raz, MD, a professor in public policy and health at the University of Rochester (N.Y.), and a hospitalist at the university medical center.
 

Should some people skip masks?

Experts say there are very few medical reasons for people to skip masks. “If you look at the research, patients with COPD [chronic obstructive pulmonary disorder], those with reactive airway, even those can breathe through a mask,” Dr. George said. Requests for exemptions due to medical reasons are usually without basis. “Obviously, if someone is incapacitated, for example, with mental health issues, that’s case by case.”

Dr. Christofides said one of her patients cited anxiety and the other cited headaches as reasons not to wear a mask. “I told the one who asked for anxiety [reasons] that she could wear ones that were less tight.” The patient with headaches told Dr. Christofides that she had a buildup of carbon dioxide in the mask because of industrial exposure. Baloney, Dr. Christofides told her.

Dr. Rizzo says one rare example of someone who can’t wear a mask might be a patient with an advanced lung condition so severe, they need extra oxygen. “These are the extreme patients where any change in oxygen and carbon dioxide could make a difference,” he said. But “that’s also the population that shouldn’t be going out in the first place.”

Dr. Raz cowrote a commentary about mask exemptions, saying doctors are faced with difficult decisions and must keep a delicate balance between public health and individual disability needs. “Inappropriate medical exemptions may inadvertently hasten viral spread and threaten public health,” she wrote.

In an interview, she says that some people do have a hard time tolerating a mask. “Probably the most common reasons are mental health issues, such as anxiety, panic and PTSD, and children with sensory processing disorders (making them oversensitive to their environment). I think there are very few pulmonary reasons.”
 

CDC, professional organization guidelines

The CDC says people should wear masks in public and when around people who don’t live in the same household. Beyond that, it simply says masks should not be worn by children under age 2, “or anyone who has trouble breathing, is unconscious, incapacitated, or otherwise unable to remove the mask without assistance.”

In mid-July, four professional organizations released a statement in response to the CDC recommendation for facial coverings. Jointly issued by the American College of Chest Physicians, the American Lung Association, the American Thoracic Society and the COPD Foundation, it states in part that people with normal lungs and “even many individuals with underlying chronic lung disease should be able to wear a non-N95 facial covering without affecting their oxygen or carbon dioxide levels.”

It acknowledges that some people will seek an exemption and doctors must weigh the patient’s concerns against the need to stop the spread of the virus. “In some instances, physician reassurance regarding the safety of the facial coverings may be all that is needed,” it states.
 

Addressing the excuses

Here are some of the common medical reasons people give for not being able to tolerate a mask:

Claustrophobia or anxiety. Dr. Raz and others suggests a “desensitizing” period, wearing the mask for longer and longer periods of time to get used to it. Parents could suggest kids wear a mask when doing something they like, such as watching television, so they equate it with something pleasant. Switching to a different kind of mask or one that fits better could also help.

Masks cause Legionnaires’ disease. Not true, experts say. Legionnaires’ is a severe form of pneumonia, the result of inhaling tiny water droplets with legionella bacteria.

It’s difficult to read lips. People can buy masks with a clear window that makes their mouth and lips visible.

Trouble breathing. Brief periods of mask use won’t have a bad effect on oxygen levels for most people.

“There is not an inherent right to be out in a pandemic with an unmasked face,” Dr. Raz says. But “you are entitled to an accommodation.” That might be using curbside pickup for food and medication. That requires much less time wearing a mask than entering a store would.

There are no “boilerplate” cards or letters to excuse people provided by the four organizations that addressed the issue, Dr. Rizzo said. If he were to write a letter asking for an exemption, he would personalize it for an individual patient’s medical condition. As to whether a state would honor it, he cannot say. The states have a patchwork of recommendations, making it difficult to say.

Dr. Rizzo tells lung disease patients who are able to go out that wearing a mask for 15-20 minutes to do an errand won’t harm their oxygen levels. And he reminds them that having an exemption, in the form of a doctor’s letter, may bring more problems. “Even with an exemption, someone may confront them” for their lack of a face covering. People with COPD have a higher risk of getting a severe illness from COVID-19, according to the CDC.

A poor combined score on tests of hearing, vision, smell, and touch is associated with a higher risk for dementia and cognitive decline among older adults, new research suggests. The study, which included almost 1,800 participants, adds to emerging evidence that even mild levels of multisensory impairment are associated with accelerated cognitive aging, the researchers noted.

Clinicians should be aware of this link between sensory impairment and dementia risk, said lead author Willa Brenowitz, PhD, assistant professor, department of psychiatry and behavioral sciences, University of California, San Francisco. “Many of these impairments are treatable, or at least physicians can monitor them; and this can improve quality of life, even if it doesn’t improve dementia risk.”

The findings were published online July 12 in Alzheimer’s and Dementia.
 

Additive effects

Previous research has focused on the link between dementia and individual senses, but this new work is unique in that it focuses on the additive effects of multiple impairments in sensory function, said Dr. Brenowitz. The study included 1,794 dementia-free participants in their 70s from the Health, Aging and Body Composition study, a prospective cohort study of healthy Black and White men and women.

Researchers tested participants’ hearing using a pure tone average without hearing aids and vision using contrast sensitivity with glasses permitted. They also measured vibrations in the big toe to assess touch and had participants identify distinctive odors such as paint thinner, roses, lemons, and onions to assess smell.

A score of 0-3 was assigned based on sample quartiles for each of the four sensory functions. Individuals with the best quartile were assigned a score of 0 and those with the worst were assigned a score of 3.

The investigators added scores across all senses to create a summary score of multisensory function (0-12) and classified the participants into tertiles of good, medium, and poor. Individuals with a score of 0 would have good function in all senses, whereas those with 12 would have poor function in all senses. Those with medium scores could have a mix of impairments.

Participants with good multisensory function were more likely to be healthier than those with poor function. They were also significantly more likely to have completed high school (85.0% vs. 72.1%), were significantly less likely to have diabetes (16.9% vs. 27.9%), and were marginally less likely to have cardiovascular disease, high blood pressure, and history of stroke.

Investigators measured cognition using the Modified Mini-Mental State (3MS) examination, a test of global cognitive function, and the Digit Symbol Substitution Test (DSST), a measure of cognitive processing speed. Cognitive testing was carried out at the beginning of the study and repeated every other year.

Dementia was defined as the use of dementia medication, being hospitalized with dementia as a primary or secondary diagnosis, or having a 3MS score 1.5 standard deviations lower than the race-stratified Health ABC study baseline mean.

Over an average follow-up of 6.3 years, 18% of participants developed dementia.
 

Dose-response increase

Results showed that, with worsening multisensory function score, the risk for dementia increased in a dose-response manner. In models adjusted for demographics and health conditions, participants with a poor multisensory function score were more than twice as likely to develop dementia than those with a good score (hazard ratio, 2.05; 95% confidence interval, 1.50-2.81; P < .001). Those with a middle multisensory function score were 1.45 times more likely to develop dementia (HR, 1.45; 95% CI, 1.09-1.91; P < .001).

Even a 1-point worse multisensory function score was associated with a 14% higher risk for dementia (95% CI, 8%-21%), while a 4-point worse score was associated with 71% higher risk for dementia (95% CI, 38%-211%).

Smell was the sensory function most strongly associated with dementia risk. Participants whose sense of smell declined by 10% had a 19% higher risk for dementia versus a 1%-3% higher risk for declines in vision, hearing, and touch.

It is not clear why smell was a stronger determinant of dementia risk. However, loss of this sense is often considered to be a marker for Alzheimer’s disease “because it is closely linked with brain regions that are affected” in that disease, said Dr. Brenowitz.

However, that does not necessarily mean smell is more important than vision or hearing, she added. “Even if hearing and vision have a smaller contribution to dementia, they have a stronger potential for intervention.” The findings suggest “some additive or cumulative” effects for loss of the different senses. “There’s an association above and beyond those which can be attributed to individual sensory domains,” she said.
 

Frailty link

After including mobility, which is a potential mediator, estimates for the multisensory function score were slightly lower. “Walking speed is pretty strongly associated with dementia risk,” Dr. Brenowitz noted. Physical frailty might help explain the link between sensory impairment and dementia risk. “It’s not clear if that’s because people with dementia are declining or because people with frailty are especially vulnerable to dementia,” she said.

The researchers also assessed the role of social support, another potential mechanism by which sensory decline, especially in hearing and vision, could influence dementia risk. Although the study did not find substantial differences in social support measures, the investigators noted that questions assessing social support were limited in scope.

Interactions between multisensory function score and race, APOE e4 allele status, and sex were not significant.

Worsening multisensory function was also linked to faster annual rates of cognitive decline as measured by both the 3MS and DSST. Each 1-point worse score was associated with faster decline (P < .05), even after adjustment for demographics and health conditions.
 

Possible mechanisms

A number of possible mechanisms may explain the link between poor sensory function and dementia. It could be that neurodegeneration underlying dementia affects the senses, or vision and/or hearing loss leads to social isolation and poor mental health, which in turn could affect dementia risk, the researchers wrote. It also is possible that cardiovascular disease or diabetes affect both dementia risk and sensory impairment.

Dr. Brenowitz noted that, because cognitive tests rely on a certain degree of vision and hearing, impairment of these senses may complicate such tests. Still to be determined is whether correcting sensory impairments, such as wearing corrective lenses or hearing aids, affects dementia risk.

Meanwhile, it might be a good idea to more regularly check sensory function, especially vision and hearing, the researchers suggested. These functions affect various aspects of health and can be assessed rather easily. However, because smell is so strongly associated with dementia risk, Dr. Brenowitz said she would like to see it also become “part of a screening tool.”

A possible study limitation cited was that the researchers checked sensory function only once. “Most likely, some of these would change over time, but at least it captured sensory function at one point,” Dr. Brenowitz said.
 

“Sheds further light”

Commenting on the study, Jo V. Rushworth, PhD, associate professor and national teaching fellow, De Montfort University Leicester (England), said it “sheds further light on the emerging links” between multisensory impairment and cognitive decline leading to dementia. “The authors show that people with even mild loss of function in various senses are more likely to develop cognitive impairment.”

Dr. Rushworth was not involved with the study but has done research in the area.

The current results suggest that measuring patients’ hearing, vision, sense of smell, and touch might “flag at-risk groups” who could be targeted for dementia prevention strategies, Dr. Rushworth noted. Such tests are noninvasive and potentially less distressing than other methods of diagnosing dementia. “Importantly, the relatively low cost and simplicity of sensory tests offer the potential for more frequent testing and the use of these methods in areas of the world where medical facilities and resources are limited.”

This new study raises the question of whether the observed sensory impairments are a cause or an effect of dementia, Dr. Rushworth noted. “As the authors suggest, decreased sensory function can lead to a decrease in social engagement, mobility, and other factors which would usually contribute to counteracting cognitive decline.”

The study raises other questions, too, said Dr. Rushworth. She noted that the participants who experienced more severe sensory impairments were, on average, 2 years older than those with the least impairments. “To what degree were the observed sensory deficits linked to normal aging rather than dementia?”

As well, Dr. Rushworth pointed out that the molecular mechanisms that “kick-start” dementia are believed to occur in midlife – so possibly at an age younger than the study participants. “Do younger people of a ‘predementia’ age range display multisensory impairments?”

Because study participants could wear glasses during vision tests but were not allowed to wear hearing aids for the hearing tests, further standardization of sensory impairment is required, Dr. Rushworth said.

“Future studies will be essential in determining the value of clinical measurement of multisensory impairment as a possible dementia indicator and prevention strategy,” she concluded.

The study was funded by the National Institute on Aging, the National Institute of Nursing Research, and the Alzheimer’s Association. Dr. Brenowitz and Dr. Rushworth have reported no relevant financial relationships.

August was National Immunization Awareness Month. ... just in time to address the precipitous drop in immunization delivered during the early months of the pandemic.

FatCamera/Getty Images

In May, the Centers for Disease Control and Prevention reported substantial reductions in vaccine doses ordered through the Vaccines for Children program after the declaration of national emergency because of COVID-19 on March 13. Approximately 2.5 million fewer doses of routine, noninfluenza vaccines were administered between Jan. 6 and April 2020, compared with a similar period last year (MMWR Morb Mortal Wkly Rep. 2020 May 15;69[19]:591-3). Declines in immunization rates were echoed by states and municipalities across the United States. Last month, the health system in which I work reported 40,000 children behind on at least one vaccine.

We all know that, when immunization rates drop, outbreaks of vaccine-preventable diseases follow. In order to avert another public health crisis, we need action as well as awareness to catch up with childhood immunizations, and that is going to take more than a single month.
 

Identify patients who’ve missed vaccinations

Simply being open and ready to vaccinate is not enough. The Centers for Disease Control and Prevention urges providers to identify patients who have missed vaccines, and call them to schedule in-person visits. Proactively let parents know about strategies implemented in your office to ensure a safe environment.

Pediatricians are accustomed to an influx of patients in the summer, as parents make sure their children have all of the vaccines required for school attendance. As noted in a Washington Post article from Aug. 4, 2020, schools have traditionally served as a backstop for immunization rates. But as many school districts opt to take education online this fall, the implications for vaccine requirements are unclear. District of Columbia public schools continue to require immunization for virtual school attendance, but it is not clear how easily this can be enforced. To read about how other school districts have chosen to address – or not address – immunization requirements for school, visit the the Immunization Action Coalition’s Repository of Resources for Maintaining Immunization during the COVID-19 Pandemic. The repository links to international, national, and state-level policies and guidance and advocacy materials, including talking points, webinars, press releases, media articles from around the United States and social media posts, as well as telehealth resources.
 

Get some inspiration to talk about vaccination

Need a little inspiration for talking to parents about vaccines? Check out the CDC’s #HowIRecommend video series. These are short videos, most under a minute in length, that explain the importance of vaccination, how to effectively address questions from parents about vaccine safety, and how clinicians routinely recommend same day vaccination to their patients. These videos are part of the CDC’s National Immunization Awareness Month (NIAM) toolkit for communication with health care professionals. A companion toolkit for communicating with parents and patients contains sample social media messages with graphics, along with educational resources to share with parents.

The “Comprehensive Vaccine Education Program – From Training to Practice,” a free online program offered by the Pediatric Infectious Diseases Society, takes a deeper dive into strategies to combat vaccine misinformation and address vaccine hesitancy. Available modules cover vaccine fundamentals, vaccine safety, clinical manifestations of vaccine-preventable diseases, and communication skills that lead to more effective conversations with patients and parents. The curriculum also includes the newest edition of The Vaccine Handbook app, a comprehensive source of practical information for vaccine providers.
 

Educate young children about vaccines

Don’t leave young children out of the conversation. Vax-Force is a children’s book that explores how vaccination works inside the human body. Dr. Vaxson the pediatrician explains how trusted doctors and scientists made Vicky the Vaccine. Her mission is to tell Willy the White Blood Cell and his Antibuddies how to find and fight bad-guy germs like measles, tetanus, and polio. The book was written by Kelsey Rowe, MD, while she was a medical student at Saint Louis University School of Medicine. Dr. Rowe, now a pediatric resident, notes, “In a world where anti-vaccination rhetoric threatens the health of our global community, this book’s mission is to teach children and adults alike that getting vaccinations is a safe, effective, and even exciting thing to do.” The book is available for purchase at https://www.vax-force.com/, and a small part of every sale is donated to Unicef USA.
 

Consider vaccination advocacy in your communities

Vaccinate Your Family, a national, nonprofit organization dedicated to protecting people of all ages from vaccine-preventable diseases, suggests that health care providers need to take an active role in raising immunization rates, not just in their own practices, but in their communities. One way to do this is to submit an opinion piece or letter to the editor to a local newspaper describing why it’s important for parents to make sure their child’s immunizations are current. Those who have never written an opinion-editorial should look at the guidance developed by Voices for Vaccines.
 

How are we doing?

Early data suggest a rebound in immunization rates in May and June, but that is unlikely to close the gap created by disruptions in health care delivery earlier in the year. Collectively, we need to set ambitious goals. Are we just trying to reach prepandemic immunization levels? In Kentucky, where I practice, only 71% of kids aged 19-45 months had received all doses of seven routinely recommended vaccines (≥4 DTaP doses, ≥3 polio doses, ≥1 MMR dose, Hib full series, ≥3 HepB doses, ≥1 varicella dose, and ≥4 PCV doses) based on 2017 National Immunization Survey data. The Healthy People 2020 target goal is 80%. Only 55% of Kentucky girls aged 13-17 years received at least one dose of HPV vaccine, and rates in boys were even lower. Flu vaccine coverage in children 6 months to 17 years also was 55%. The status quo sets the bar too low. To see how your state is doing, check out the interactive map developed by the American Academy of Pediatrics.

Are we attempting to avoid disaster or can we seize the opportunity to protect more children than ever from vaccine-preventable diseases? The latter would really be something to celebrate.

August was National Immunization Awareness Month. ... just in time to address the precipitous drop in immunization delivered during the early months of the pandemic.

In May, the Centers for Disease Control and Prevention reported substantial reductions in vaccine doses ordered through the Vaccines for Children program after the declaration of national emergency because of COVID-19 on March 13. Approximately 2.5 million fewer doses of routine, noninfluenza vaccines were administered between Jan. 6 and April 2020, compared with a similar period last year (MMWR Morb Mortal Wkly Rep. 2020 May 15;69[19]:591-3). Declines in immunization rates were echoed by states and municipalities across the United States. Last month, the health system in which I work reported 40,000 children behind on at least one vaccine.

We all know that, when immunization rates drop, outbreaks of vaccine-preventable diseases follow. In order to avert another public health crisis, we need action as well as awareness to catch up with childhood immunizations, and that is going to take more than a single month.
 

Identify patients who’ve missed vaccinations

Simply being open and ready to vaccinate is not enough. The Centers for Disease Control and Prevention urges providers to identify patients who have missed vaccines, and call them to schedule in-person visits. Proactively let parents know about strategies implemented in your office to ensure a safe environment.

The Food and Drug Administration has approved  viltolarsen (Viltepso, NS Pharma), the second drug therapy for Duchenne muscular dystrophy in patients with a confirmed mutation amenable to exon 53 skipping. The FDA approved golodirsen (Vyondys 53, Sarepta Therapeutics) for this indication last year.  

“The FDA is committed to fostering drug development for serious neurological disorders like Duchenne muscular dystrophy,” Billy Dunn, MD, director, Office of Neuroscience of the FDA’s Center for Drug Evaluation and Research, said in a statement.

The approval of viltolarsen provides “an important treatment option for Duchenne muscular dystrophy patients with this confirmed mutation,” Dr. Dunn said.

Viltolarsen is an antisense oligonucleotide that promotes production of functional dystrophin by masking exon 53 in the dystrophin gene. It was evaluated in two studies involving 32 male patients.

In one study of 16 patients, the increase in dystrophin production was established in eight patients receiving viltolarsen at the recommended dose. In this study, dystrophin levels increased, on average, from 0.6% of normal at baseline to 5.9% of normal at week 25.

The increase in dystrophin production is “reasonably likely to predict clinical benefit,” but a “clinical benefit of the drug has not been established,” the FDA said.

In making the decision, the FDA considered the potential risks associated with the drug, the life-threatening and debilitating nature of the disease, and the lack of available therapies.

Viltolarsen was approved under the FDA’s accelerated approval pathway, which provides for the approval of drugs that treat serious or life-threatening diseases and generally offer a meaningful advantage over existing treatments.

As part of the accelerated approval, the FDA requires the company to do a clinical trial to confirm the drug’s clinical benefit. If the trial fails to verify clinical benefit, the FDA may start proceedings to withdraw approval of the drug, the agency said.

The most common side effects with viltolarsen are upper respiratory tract infection, injection-site reaction, cough, and fever.

Kidney toxicity was not observed in the clinical studies, but the clinical experience with the drug is limited, and kidney toxicity, including potentially fatal glomerulonephritis, has been observed with some antisense oligonucleotides.

“Kidney function should be monitored in patients taking Viltepso,” the FDA advises.
