Israeli officials are reporting a 30% decrease in the effectiveness of the Pfizer/BioNTech vaccine to prevent SARS-CoV-2 infection and mild to moderate cases of COVID-19. At the same time, protection against hospitalization and severe illness remains robust.

The country’s Ministry of Health data cited high levels of circulating Delta variant and a relaxation of public health measures in early June for the drop in the vaccine’s prevention of “breakthrough” cases from 94% to 64% in recent weeks.

However, it is important to consider the findings in context, experts cautioned.

“My overall take on this that the vaccine is highly protective against the endpoints that matter – hospitalization and severe disease,” Anna Durbin, MD, told this news organization.

“I was very pleasantly surprised with the very high efficacy against hospitalization and severe disease – even against the Delta variant,” added Dr. Durbin, professor of medicine at Johns Hopkins University, Baltimore.

Ali Mokdad, PhD, of the Institute for Health Metrics at the University of Washington, Seattle, agreed that the high degree of protection against severe outcomes should be the focus.

“That’s the whole idea. You want to defend against COVID-19. So even if someone is infected, they don’t end up in the hospital or in the morgue,” he said in an interview.

Compared with an earlier report, the efficacy of the Pfizer vaccine against hospitalization fell slightly from 98% to 93%.

“For me, the fact that there is increased infection from the Delta variant after the vaccines such as Pfizer is of course a concern. But the positive news is that there is 93% prevention against severe disease or mortality,” added Dr. Mokdad, who is also professor of global health at University of Washington.

In addition, the absolute numbers remain relatively small. The Ministry of Health data show that, of the 63 Israelis hospitalized with COVID-19 nationwide on July 3, 34 were in critical condition.
 

Unrealistic expectations?

People may have unrealistic expectations regarding breakthrough infections, Dr. Durbin said. “It seems that people are almost expecting ‘sterilizing immunity’ from these vaccines,” she said, explaining that would mean complete protection from infection.

Expectations may be high “because these vaccines have been so effective,” added Dr. Durbin, who is also affiliated with the Johns Hopkins Center for Global Health.

The higher the number of vaccinated residents, the more breakthrough cases will be reported, epidemiologist Katelyn Jetelina, PhD, MPH, assistant professor of epidemiology, human genetics, and environmental sciences at the University of Texas Science Center at Houston, wrote in her “Your Local Epidemiologist” blog.

This could apply to Israel, with an estimated 60% of adults in Israel fully vaccinated and 65% receiving at least one dose as of July 5, Our World in Data figures show.

How the updated figures were reported could be confusing, Dr. Jetelina said. Israel’s Health Minister Chezy Levy noted that “55% of the newly infected had been vaccinated” in a radio interview announcing the results.

“This language is important because it’s very different than ‘half of vaccinated people were infected,’ ” Dr. Jetelina noted.

Israel had a 7-day rolling average of 324 new confirmed COVID-19 cases as of July 5. Assuming 55% of these cases were among vaccinated people, that would mean 178 people experienced breakthrough infections.

In contrast, almost 6 million people in Israel are fully vaccinated. If 55% of them experienced breakthrough infections, the number would be much higher – more than 3 million.

Dr. Jetelina added that more details about the new Israel figures would be helpful, including the severity of COVID-19 among the vaccinated cases and breakdown of infections between adults and children.
 

Next steps

Israeli health officials are weighing the necessity of a third or booster dose of the vaccine. Whether they will reinstate public health measures to prevent spread of COVID-19 also remains unknown.

Going forward, Israel intends to study whether factors such as age, comorbidities, or time since immunization affect risk for breakthrough infections among people vaccinated against COVID-19.

“We want to prevent people from getting hospitalized, seriously ill, and of course, dying. It’s encouraging these vaccines will be able to have a high impact on those outcomes,” Dr. Durbin said. “We just need to get people vaccinated.”
 

A call for better global surveillance

A global surveillance system is a potential solution to track and respond to the growing threat of the Delta variant and other variants of concern, Scott P. Layne, MD, and Jeffery K. Taubenberger, MD, PhD, wrote in a July 7, 2021, editorial in Science Translational Medicine.

One goal, Dr. Layne said in an interview, is to highlight “the compelling need for a new global COVID-19 program of surveillance and offer a blueprint for building it.” A second aim is to promote global cooperation among key advisers and leaders in the G7, G20, and Asia-Pacific Economic Cooperation nations.

“It’s an uphill struggle with superpower discords, global warming, cybersecurity, and pandemics all competing for finite attention,” Dr. Layne said. “However, what other options do we have for taming the so-called forever virus?”

Dr. Mokdad and Dr. Jetelina had no relevant disclosures. Dr. Durban disclosed she was the site primary investigator for the phase 3 AstraZeneca vaccine trial and an investigator on the Pfizer COVID-19 vaccine trial.

With two sets of Clostridioides difficile recommendations being published within a month of each other, clinicians may find themselves trying to reconcile some of the conflicts between the two guidelines.

The first set, published June 1 by the American College of Gastroenterology, focuses on fecal microbiota transplantation (FMT) and the antibiotic vancomycin. The second, published June 24 by the Infectious Diseases Society of America and Society for Healthcare Epidemiology of America, drives a shift in treatment for initial episodes and short-term recurrence from vancomycin to fidaxomicin and, in some cases, adding on the monoclonal antibody bezlotoxumab, both made by Merck.

The updates are timely because researchers are now recognizing that C. difficile can colonize people without causing symptoms, David Johnson, MD, professor of medicine and chief of gastroenterology at the Eastern Virginia School of Medicine, Norfolk, said in an interview. He was not involved in writing either set of guidelines. “C. diff infection was a hospital-type infection, but we’re now seeing it in up to approximately 35%-50% of patients coming from the community, so it’s a big concern.”

Although the guidelines agree on which treatments are effective, the recommendations give the options a different emphasis.

Infectious disease specialist Stuart Johnson, MD, professor of medicine at Loyola University Medical Center in Maywood, Ill., and a physician researcher at Edward Hines Jr. Veterans Affairs Hospital in Hines, Ill., is the first author in the IDSA/SHEA guidelines. He told this news organization that one reason the two sets of recommendations may diverge in emphasis for initial and recurrent C. difficile is that “everyone has a different way of looking at things.” Compared with infectious disease specialists like him, he said, gastroenterologists “for the most part see the world a little different and have their own bent on things.” 

The differences between the two guidelines relate to the first-line therapy for people with an initial or recurrent C. difficile episode. For an initial episode, the IDSA/SHEA authors conditionally recommend fidaxomicin as first preferred choice over vancomycin, with a moderate certainty of evidence. They noted that implementing this recommendation depends on “available resources,” a reference to the higher cost and difficulty of access associated with fidaxomicin.

Gastroenterologist Monika Fischer, MD, an associate professor of medicine at Indiana University, Indianapolis, is one of the authors of the ACG guidelines. She told this news organization that the cost difference between fidaxomicin and vancomycin is considerable and finds the choice to foreground fidaxomicin puzzling. “They did not reference any new data compared to those we have published.” Their recommendation may make sense in terms of efficacy, but real-world demands require attention to cost and reimbursement. “They themselves state this in their recommendations,” she noted. 

Dr. Fischer cited a ballpark of about $100 for a course of vancomycin, compared with about $3,000 for a course of fidaxomicin. The IDSA/SHEA guidelines do cite vancomycin as an acceptable alternative. According to Dr. Fischer, the ACG guidelines authors discussed fidaxomicin and concluded that there just wasn’t enough evidence to justify favoring this antibiotic over vancomycin, given the cost-benefit imbalance. The ACG guidelines call for a standard course of oral vancomycin for a first, nonsevere C. difficile episode, listing oral fidaxomicin or oral metronidazole as alternatives.

For a recurrence, the IDSA/SHEA authors also favor fidaxomicin in a conditional recommendation over a standard course of vancomycin. For multiple recurrences, a tapered and pulsed vancomycin regimen, vancomycin followed by rifaximin, or FMT are also options.

Dr. David Johnson said that these recommendations favoring fidaxomicin are “surprising,” and that lower costs of vancomycin outweigh the benefit of fidaxomicin, given more-or-less comparable data on cure rates.

In contrast, the ACG guidelines recommend that an initial recurrence be treated with a tapering dose of vancomycin, and call for FMT for patients who are eligible and who experience a second or more C. difficile recurrences after a round of pulsed vancomycin.

Dr. Stuart Johnson said that FMT carries its own special set of issues. “If you don’t have a donor program set up, you have to rely on a stool bank,” noting that one widely used stool bank “basically had to stop making the product because of the coronavirus.” Costs for FMT products have doubled in recent years, and because Food and Drug Administration approval of the therapy is lacking, insurance does not cover it.

Dr. David Johnson also said that he is not “terribly happy” about the ACG recommendation for vancomycin prophylaxis. “It may help, but it also can have off-target effects against colonic bacterial flora, so we would not agree with that recommendation.”

The IDSA/SHEA authors also conditionally recommend bezlotoxumab, on very low certainty of evidence, as a cotherapy with standard of care antibiotics for recurrence prevention in patients with an episode in the last 6 months, particularly for patients at high recurrence risk “where logistics is not an issue.” The FDA has warned that this monoclonal antibody should be used with great care in patients with heart failure and only when benefits outweigh risks.

The ACG guidelines conditionally recommend considering bezlotoxumab to prevent recurrence in patients with specific risk factors, including age over 65 years and severe presentation. The IDSA/SHEA guidelines expand this population to anyone with a recurrence within 6 months, Dr. Fischer pointed out.

The antibody treatment “does offer another 10% absolute reduction in recurrent C. diff disease,” said Dr. Stuart Johnson, which is a “helpful option and primarily for people who have had recurrent C. diff already.” In general, he said, for both drugs, “access is still something we have to work with.”

In a commentary on the ACG guidelines, Dr. David Johnson wrote that there is good evidence that bezlotoxumab prevents relapse, especially in patients with specific risk factors. The hitch is the $4,500 price tag for a 1,000-mg vial, with a recommended dose of 10 mg/kg.

Dr. Stuart Johnson agreed that the costs of the fidaxomicin and bezlotoxumab are important considerations. In addition, there are logistical issues with using the antibody because most hospitals don’t offer infusions, which pushes patients to infusion centers.

Regardless, he added, “we’re happy that we have new options.”

Dr. Fischer, Dr. Stuart Johnson, and Dr. David Johnson reported no relevant financial relationships.

Dr. Fischer, Dr. Stuart Johnson, and Dr. David Johnson reported no relevant financial relationships.

Sublingual immunotherapy (SLIT) emerged over a century ago as a gentler alternative to allergy shots. It uses the same antigens found in allergy shots, delivering them through tablets or drops under the tongue rather than by injecting them into the skin.

Yet injection immunotherapy has been the mainstay of allergy treatment in the United States. Allergy shots are “the bread and butter, keeping the lights on at allergy practices,” said allergist Sakina Bajowala, MD, of Kaneland Allergy and Asthma Center, in the Chicago area. So even “when environmental SLIT showed quite clearly that it had efficacy, people were so slow to adapt.”

SLIT – a daily treatment that builds protection from allergens gradually over years with few side effects – is popular around the globe, particularly for environmental allergies. But only a handful of clinics offer food SLIT. Even though recent trials in peanut-allergic children show that SLIT is far safer than oral immunotherapy and about as effective as the Food and Drug Administration–approved peanut-allergy product and has lasting benefits for toddlers, many allergists lack experience with customized immunotherapies and hesitate to offer an unregulated treatment for which the evidence base is still emerging.
 

Why hasn’t food allergy SLIT caught on?

One issue is that there is scant evidence from randomized, controlled trials. The treatments that clinics offer often hinge on insurance coverage, and increasingly, insurers only cover FDA-approved products. FDA approval requires thousands of patients being enrolled in long, expensive studies to prove the treatment’s merit. In a similar vein, doctors are trained to question methods that lack a strong publication base, for good reason.

Yet SLIT caught the attention of pioneering physicians who were intrigued by this “low-and-slow” immune-modifying approach, despite limited published evidence, and they sought real-world experience.

The late physician David Morris, MD, came across SLIT in the 1960s while searching for alternative ways to help mold-allergic farmers who were suffering terrible side effects from allergy shots. Dr. Morris attended conferences, learned more about sublingual techniques, got board certified in allergy, and opened Allergy Associates of La Crosse (Wis.), in 1970 to offer SLIT as a treatment for food and environmental allergies.

Dr. Morris and colleagues developed a protocol to create custom SLIT drops tailored to individual patients’ clinical histories and allergy test results. The method has been used to treat more than 200,000 patients. It has been used by allergist Nikhila Schroeder, MD, MEng, who learned SLIT methods while treating nearly 1,000 patients at Allergy Associates. In 2018, she opened her own direct-care SLIT practice, Allergenuity Health, in the Charlotte metropolitan area of North Carolina (see part 2 of this series).

Dr. Bajowala’s clinic offers SLIT in addition to oral immunotherapy (OIT). She was encouraged by the recent toddler SLIT data but wondered whether it would translate to a real-world setting. According to her calculations, the published protocol – according to which participants receive up to 4 mg/d over 6 months and continue receiving a daily maintenance dose of 4 mg for 3 years – would cost $10,000 per patient.

With this dosing regimen, the intervention is unaffordable, Dr. Bajowala said. And “there’s no way to make it cheaper because that’s the raw materials cost. It does not include labor or bottles or profit at all. That’s just $10,000 in peanut extract.”

Owing to cost, Dr. Bajowala’s clinic generally uses SLIT as a bridge to OIT. Her food allergy patients receive up to 1 mg/d and remain at that dose for a month or so before transitioning to OIT, “for which the supplies are orders of magnitude cheaper,” she said.

Dr. Schroeder said there is evidence for efficacy at microgram and even nanogram dosing – much lower than used in the recent food SLIT trials. Maintenance doses range from 50 ng/d to 25 mcg/d for environmental SLIT and 4-37 mcg/d for food SLIT, she said. The La Crosse method uses even lower dose ranges.

However, dosing information is not readily available, Dr. Schroeder noted. She has spent years scrutinizing articles and compiling information from allergen extract suppliers – all the while treating hundreds of SLIT patients. “I have had to expend a lot of time and effort,” said Dr. Schroeder. “It’s really hard to explain quickly.”

In the published literature, SLIT dosing recommendations vary widely. According to a 2007 analysis, environmental allergy symptoms improved with doses over a 1,000-fold range. What’s more, success did not scale with increased dosing and seemed to depend more on frequency and duration of treatment.

There are fewer studies regarding food SLIT. The most promising data come from recent trials of peanut-allergic children led by Edwin Kim, MD, director of the UNC Food Allergy Initiative, University of North Carolina at Chapel Hill. Still, “I am nervous to tell people to go do this based on 150 kids at one site,” Dr. Kim said. “We need to have a gigantic study across multiple sites that actually confirms what we have found in our single center.”

Because there are few published trials of food SLIT, confusion about which doses are optimal, how early to start, and how long the benefits last will be a barrier for many clinicians, said Douglas Mack, MD, FRCPC, assistant clinical professor in pediatrics at McMaster University, Hamilton, Ont.

Much could be learned from Allergy Associates of La Crosse, Allergenuity Health, and other clinics with SLIT experience involving thousands of patients. But that real-world data are messy and difficult to publish. Plus, it is hard for private allergists to find time to review charts, analyze data, and draft papers alongside seeing patients and running a clinic – especially without students and interns, who typically assist with academic research, Dr. Schroeder said.

Ruchi Gupta, MD, MPH, professor of pediatrics and medicine at Northwestern University, Chicago, and colleagues worked with a La Crosse team 6 or 7 years ago to try to analyze and publish SLIT outcomes for 121 peanut-allergic children who were treated for food and environmental allergies at the Wisconsin clinic. The researchers had hoped to publish an article describing caregiver-reported and clinical outcomes.

Among 73 caregivers who responded to a survey, more than half reported improved eczema, asthma, and environmental allergy symptoms, and virtually all families said SLIT calmed anxieties and minimized fear of allergic reactions. However, the clinical outcomes – skinprick test results, immune changes, and oral food challenges – were not as robust. And the data were incomplete. Some patients had traveled to La Crosse for SLIT drops but underwent skin and blood testing with their local allergist. Compiling records is “so much harder when you’re not doing a prospective clinical trial,” Dr. Gupta said.

The caregiver-reported outcomes were presented as a poster at the 2015 annual meeting of the American College of Allergy, Asthma, and Immunology and the 2016 annual meeting of the Pediatric Academic Society, said Jeff Kessler, MBA, FACHE, who is practice executive at La Crosse. However, with only self-reported data and no convincing lab metrics, the findings were never submitted for publication.

Others are eager to see clearer proof that SLIT works at doses lower than those published in the most recent trials. “If we can get efficacy with lower doses, that means we can increase accessibility, because we can lower the cost,” Dr. Bajowala said.

Robert Wood, MD, professor of pediatrics and director of pediatric allergy and immunology at Johns Hopkins University, Baltimore, has a pending grant proposal for a multifood trial of SLIT. “It’s a big missing piece,” he said.

Dr. Mack said that in Canada there was “almost an instant change in group think” when the Canadian Society of Allergy and Clinical Immunology published guidelines in support of OIT. With the new guidelines, “people are less concerned about liability. Once they start getting into OIT, I think you’re going to see SLIT coming right along for the ride.”

The shift will be slower in the United States, which has 20 times as many practicing allergists as Canada. Nevertheless, “I totally think SLIT has a place at the table,” Dr. Mack said. “I hope we start to see more high-quality data and people start to use it and experiment with it a bit and see how it works.”

With degrees in electrical engineering and computer science from the Massachusetts Institute of Technology, Nikhila Schroeder, MD, MEng, brings a problem-solving mindset to medicine.

Being a doctor means having to “figure out all aspects of [a patient’s] situation and do my best to come up with an answer,” said Dr. Schroeder, who founded Allergenuity Health, a solo allergy practice in Huntersville, N.C., with her husband James, who serves as practice executive. It’s “being a medical detective for your patient.”

Yet, during her training, Dr. Schroeder found that market-driven health care makes it hard to practice medicine with a patient’s best interest foremost. Procedures for diagnosing and treating disease cater to insurance companies’ reimbursement policies. “You wind up having to tailor your care to whatever insurance will cover,” she said.

Insurers, in turn, look for evidence from large, peer-reviewed studies to prove that a treatment works. Many physicians hesitate to offer therapies that aren’t covered by insurance, for both liability and financial reasons. So treatment tends to be limited to those options that were rigorously vetted in long, costly, multisite trials that are difficult to conduct without a corporate sponsor.

This is why there is still only one licensed treatment for people with food allergies – a set of standardized peanut powder capsules (Palforzia) that was approved by the Food and Drug Administration in early 2020 for peanut-allergic children aged 4-17 years. A small but growing number of allergists offer unapproved oral immunotherapy (OIT) using commercial food products to treat allergies to peanuts and other foods.

Even fewer allergists treat food allergy patients with another immune-modifying treatment, sublingual immunotherapy (SLIT), which delivers allergens through liquid drops held for several minutes under the tongue. Since 2018, Allergenuity Health, which offers SLIT to treat food and environmental allergies, has provided care to more than 400 patients. More than a third have come from out of state.

The clinic uses a direct-care approach. Rather than taking insurance, the clinic offers a monthly billing program that includes tests, SLIT bottles, and access to Dr. Schroeder via phone, email, or text. “I’m only contracted with the patient, and my only focus is the patient,” Dr. Schroeder said in an interview.
 

Unforgettable day

Allergy was not on Dr. Schroeder’s radar in medical school. She wanted to be a surgeon. But she loved working with children, so she did a pediatrics residency at the University of Virginia Children’s Hospital in Charlottesville. There Dr. Schroeder started seeing kids with eczema and allergies. While covering a friend’s clinic shift in 2010, she was thrust into an emergency. A family who didn’t speak English had just brought in their screaming 6-month-old baby, red and puffy with hives. “We didn’t know what was going on with this child,” Dr. Schroeder said. “Somehow I was elected to go in there.”

All of a sudden, things got quiet. Yet the baby was still screaming, mouth wide open. Dr. Schroeder had learned about anaphylaxis but had never witnessed it – until that day. The baby›s airways swelled so much that the crying became hoarse and soft. After working with a nurse to administer epinephrine, Dr. Schroeder saw something equally unforgettable: The baby’s heart rate soared, but within minutes the hives and swelling subsided and smiles returned. “It was incredible how quickly things changed,” Dr. Schroeder said. The baby had a reaction to rice, an uncommon allergen.

Dr. Schroeder stayed at UVA 2 more years to complete an allergy and immunology fellowship. She learned to diagnose food allergies but became frustrated having to tell patients they had little recourse but to avoid the food and to check in every year or 2. “I was, like, aren’t we specialists? Shouldn’t we have a little more expertise and maybe see if there are ways we could change this?” Dr. Schroeder said.

During those years, allergy shots were the only form of immunotherapy being taught to fellows. At clinic, Dr. Schroeder served as backup to the nurses when someone reacted to shots. She was troubled that some patients needed epinephrine to stop asthma attacks caused by injections they had received as treatment. The idea of injecting substances under the skin seemed akin to vaccination – where “you want to aggravate the immune system, you want it to get revved up, you want to build it up to fight,” she said. “But that’s not what you want for allergy. You want to tone it down. It didn’t really, to be honest, make a lot of sense to me.”

Dr. Schroeder started digging and asking questions. How does the immune system decide what is safe? Which cells and molecules communicate these decisions? She thought about babies and how they “learn” by putting stuff into their mouths. “If we don’t tolerate most of what we take in there, we wouldn’t survive,” Dr. Schroeder said. “It makes a lot of sense that a lot of tolerance begins with cells of the mouth.”

Dr. Schroeder discussed these concepts with her attendings. “They were all, like, no, there’s really no good evidence for that,” she said. But at some point, someone mentioned sublingual immunotherapy, and Schroeder came across Allergy Associates of La Crosse (Wis.).

The clinic’s late founder, David Morris, MD, learned about SLIT in the 1960s as an alternative option for farmers who suffered terrible side effects from injection immunotherapy they received to treat their mold allergies. Dr. Morris attended conferences, learned more about sublingual techniques – at times seeking advice from European allergists who offered SLIT – and became board certified in allergy before opening the La Crosse clinic in 1970. According to the clinic, more than 200,000 patients with environmental and food allergies have been treated with its SLIT protocol.

Dr. Schroeder was shocked to discover that this clinic had existed for 40 years, yet “I, as an allergist, had heard nothing about them,” she said.

Toward the end of her fellowship, OIT was becoming more well known. But she felt its risks were often downplayed. After years of talking with food allergy patients, Schroeder realized that most didn’t actually care about eating peanut butter sandwiches or sesame or walnuts. “Often I would hear, through tears: ‘I just want my child to be able to sit with their friends at lunch, to not be put at this other table, to not feel so isolated,’ ” she said. What mattered most to many families was gaining enough protection to not feel anxious about participating in social activities involving food.

Dr. Schroeder had a growing sense that SLIT – given its ease, safety, and sensible route of allergen delivery – seemed more useful. She wanted to learn more.

Her mentors urged her to stay in academia instead. “They were, like, you have a good academic reputation. You’re a solid thinker. You’re great at what you do. Do the traditional stuff,” Dr. Schroeder said.

Despite these admonitions, Dr. Schroeder left academia and took a job at La Crosse after completing her allergy fellowship. Determined to see whether SLIT could be effective, “I decided in the end, you know what, I have to go do this,” she said. “I need to know, and the only way I’m going to know is to do it, because no one was giving me good information.”

Before treating anyone with SLIT, Dr. Schroeder tried it herself – as a La Crosse patient. Growing up with severe eczema, eye swelling, and chronic nasal congestion leading to sinus infections, “I myself was a severely allergic person,” she said. Within several months, Dr. Schroeder saw dramatic improvement in her symptoms – “a night and day difference.” She experienced some mouth tingling, one of SLIT’s most common side effects, but found it “very tolerable, very mild.”

Allergenuity Health doesn’t aim to promote SLIT as the best treatment, said Dr. Schroeder, who has helped some families use avoidance or OIT as a better option. “An initial evaluation is always about proper diagnosis and education about all the treatment options available. Really, the point is education – be a detective for them and figure out what’s going on, be honest about what we know and what we don’t know, and give them the tools to figure out how to proceed.”

This is why there is still only one licensed treatment for people with food allergies – a set of standardized peanut powder capsules (Palforzia) that was approved by the Food and Drug Administration in early 2020 for peanut-allergic children aged 4-17 years. A small but growing number of allergists offer unapproved oral immunotherapy (OIT) using commercial food products to treat allergies to peanuts and other foods.

Even fewer allergists treat food allergy patients with another immune-modifying treatment, sublingual immunotherapy (SLIT), which delivers allergens through liquid drops held for several minutes under the tongue. Since 2018, Allergenuity Health, which offers SLIT to treat food and environmental allergies, has provided care to more than 400 patients. More than a third have come from out of state.

The clinic uses a direct-care approach. Rather than taking insurance, the clinic offers a monthly billing program that includes tests, SLIT bottles, and access to Dr. Schroeder via phone, email, or text. “I’m only contracted with the patient, and my only focus is the patient,” Dr. Schroeder said in an interview.
 

Unforgettable day

Allergy was not on Dr. Schroeder’s radar in medical school. She wanted to be a surgeon. But she loved working with children, so she did a pediatrics residency at the University of Virginia Children’s Hospital in Charlottesville. There Dr. Schroeder started seeing kids with eczema and allergies. While covering a friend’s clinic shift in 2010, she was thrust into an emergency. A family who didn’t speak English had just brought in their screaming 6-month-old baby, red and puffy with hives. “We didn’t know what was going on with this child,” Dr. Schroeder said. “Somehow I was elected to go in there.”

All of a sudden, things got quiet. Yet the baby was still screaming, mouth wide open. Dr. Schroeder had learned about anaphylaxis but had never witnessed it – until that day. The baby›s airways swelled so much that the crying became hoarse and soft. After working with a nurse to administer epinephrine, Dr. Schroeder saw something equally unforgettable: The baby’s heart rate soared, but within minutes the hives and swelling subsided and smiles returned. “It was incredible how quickly things changed,” Dr. Schroeder said. The baby had a reaction to rice, an uncommon allergen.

Dr. Schroeder stayed at UVA 2 more years to complete an allergy and immunology fellowship. She learned to diagnose food allergies but became frustrated having to tell patients they had little recourse but to avoid the food and to check in every year or 2. “I was, like, aren’t we specialists? Shouldn’t we have a little more expertise and maybe see if there are ways we could change this?” Dr. Schroeder said.

During those years, allergy shots were the only form of immunotherapy being taught to fellows. At clinic, Dr. Schroeder served as backup to the nurses when someone reacted to shots. She was troubled that some patients needed epinephrine to stop asthma attacks caused by injections they had received as treatment. The idea of injecting substances under the skin seemed akin to vaccination – where “you want to aggravate the immune system, you want it to get revved up, you want to build it up to fight,” she said. “But that’s not what you want for allergy. You want to tone it down. It didn’t really, to be honest, make a lot of sense to me.”

Dr. Schroeder started digging and asking questions. How does the immune system decide what is safe? Which cells and molecules communicate these decisions? She thought about babies and how they “learn” by putting stuff into their mouths. “If we don’t tolerate most of what we take in there, we wouldn’t survive,” Dr. Schroeder said. “It makes a lot of sense that a lot of tolerance begins with cells of the mouth.”

Dr. Schroeder discussed these concepts with her attendings. “They were all, like, no, there’s really no good evidence for that,” she said. But at some point, someone mentioned sublingual immunotherapy, and Schroeder came across Allergy Associates of La Crosse (Wis.).

The clinic’s late founder, David Morris, MD, learned about SLIT in the 1960s as an alternative option for farmers who suffered terrible side effects from injection immunotherapy they received to treat their mold allergies. Dr. Morris attended conferences, learned more about sublingual techniques – at times seeking advice from European allergists who offered SLIT – and became board certified in allergy before opening the La Crosse clinic in 1970. According to the clinic, more than 200,000 patients with environmental and food allergies have been treated with its SLIT protocol.

Dr. Schroeder was shocked to discover that this clinic had existed for 40 years, yet “I, as an allergist, had heard nothing about them,” she said.

Toward the end of her fellowship, OIT was becoming more well known. But she felt its risks were often downplayed. After years of talking with food allergy patients, Schroeder realized that most didn’t actually care about eating peanut butter sandwiches or sesame or walnuts. “Often I would hear, through tears: ‘I just want my child to be able to sit with their friends at lunch, to not be put at this other table, to not feel so isolated,’ ” she said. What mattered most to many families was gaining enough protection to not feel anxious about participating in social activities involving food.

Dr. Schroeder had a growing sense that SLIT – given its ease, safety, and sensible route of allergen delivery – seemed more useful. She wanted to learn more.

Her mentors urged her to stay in academia instead. “They were, like, you have a good academic reputation. You’re a solid thinker. You’re great at what you do. Do the traditional stuff,” Dr. Schroeder said.

Despite these admonitions, Dr. Schroeder left academia and took a job at La Crosse after completing her allergy fellowship. Determined to see whether SLIT could be effective, “I decided in the end, you know what, I have to go do this,” she said. “I need to know, and the only way I’m going to know is to do it, because no one was giving me good information.”

Before treating anyone with SLIT, Dr. Schroeder tried it herself – as a La Crosse patient. Growing up with severe eczema, eye swelling, and chronic nasal congestion leading to sinus infections, “I myself was a severely allergic person,” she said. Within several months, Dr. Schroeder saw dramatic improvement in her symptoms – “a night and day difference.” She experienced some mouth tingling, one of SLIT’s most common side effects, but found it “very tolerable, very mild.”

Allergenuity Health doesn’t aim to promote SLIT as the best treatment, said Dr. Schroeder, who has helped some families use avoidance or OIT as a better option. “An initial evaluation is always about proper diagnosis and education about all the treatment options available. Really, the point is education – be a detective for them and figure out what’s going on, be honest about what we know and what we don’t know, and give them the tools to figure out how to proceed.”

With degrees in electrical engineering and computer science from the Massachusetts Institute of Technology, Nikhila Schroeder, MD, MEng, brings a problem-solving mindset to medicine.

Being a doctor means having to “figure out all aspects of [a patient’s] situation and do my best to come up with an answer,” said Dr. Schroeder, who founded Allergenuity Health, a solo allergy practice in Huntersville, N.C., with her husband James, who serves as practice executive. It’s “being a medical detective for your patient.”

Yet, during her training, Dr. Schroeder found that market-driven health care makes it hard to practice medicine with a patient’s best interest foremost. Procedures for diagnosing and treating disease cater to insurance companies’ reimbursement policies. “You wind up having to tailor your care to whatever insurance will cover,” she said.

Insurers, in turn, look for evidence from large, peer-reviewed studies to prove that a treatment works. Many physicians hesitate to offer therapies that aren’t covered by insurance, for both liability and financial reasons. So treatment tends to be limited to those options that were rigorously vetted in long, costly, multisite trials that are difficult to conduct without a corporate sponsor.

For the 32 million people in the United States with food allergies, those who seek relief beyond constant vigilance and EpiPens face a confusing treatment landscape. In January 2020, the Food and Drug Administration approved an oral immunotherapy product (Palforzia) for peanut-allergic children. Yet the product’s ill-timed release during a pandemic and its black-box warning about the risk for anaphylaxis has slowed uptake.

A small number of allergists offer home-grown oral immunotherapy (OIT), which builds protection by exposing patients to increasing daily doses of commercial food products over months. However, as with Palforzia, allergic reactions are common during treatment, and the hard-earned protection can fade if not maintained with regular dosing.

An alternate approach, sublingual immunotherapy (SLIT), delivers food proteins through liquid drops held in the mouth – a site rich in tolerance-inducing immune cells. In a 2019 study of peanut-allergic children aged 1-11 years, SLIT offered a level of protection on par with Palforzia while causing considerably fewer adverse events. And at the 2021 annual meeting of the American Academy of Allergy, Asthma and Immunology, researchers reported that SLIT produced stronger, more durable benefits in toddlers aged 1-4.

Sublingual immunotherapy is “a bunch of drops you put under your tongue, you hold it for a couple minutes, and then you’re done for the day,” said Edwin Kim, MD, director of the UNC Food Allergy Initiative, University of North Carolina at Chapel Hill, who led the two recent studies. For protecting against accidental ingestions, SLIT “is pushing pretty close to what OIT is able to provide but seemingly with a superior ease of administration and safety profile.”

Many parents don’t necessarily want their allergic kids to be able to eat a peanut butter sandwich – but do want them to be able to safely sit at the same lunch table and attend birthday parties with other kids. SLIT achieves this level of protection about as well as OIT, with fewer side effects.

Still, because of concerns about the treatment’s cost, unclear dosing regimens, and lack of FDA approval, very few U.S. allergists – likely less than 5% – offer sublingual immunotherapy to treat food allergies, making SLIT even less available than OIT.
 

Concerns about SLIT

One possible reason: Success is slower and less visible for SLIT. When patients undergo OIT, they build up to dosing with the actual food. “To a family who has a concern about their kid reacting, they can see them eating chunks of peanut in our office. That is really encouraging,” said Douglas Mack, MD, FRCPC, an allergist with Halton Pediatric Allergy and assistant clinical professor of pediatrics at McMaster University, Hamilton, Ont.

On the other hand, ingestion isn’t the focus for SLIT, so progress is harder to measure using metrics in published trials. After holding SLIT drops under the tongue, some patients spit them out. If they swallow the dose, it’s a vanishingly small amount. Immune changes that reflect increasing tolerance, such as a decrease in IgE antibodies, tend to be more gradual with SLIT than with OIT. And because SLIT is only offered in private clinics, such tests are not conducted as regularly as they would be for published trials.

But there may be a bigger factor: Some think earlier trials comparing the two immunotherapy regimens gave SLIT a bad rap. For example, in studies of milk- and peanut-allergic children conducted in 2011 and 2014, investigators concluded that SLIT was safer and that OIT appeared to be more effective. However, those trials compared SLIT with OIT using a much higher dose (2,000 mg) than is used in the licensed product (300 mg).

Over the years, endpoints for food allergy treatment trials have shifted from enabling patients to eat a full serving of their allergen to merely raising their threshold to guard against accidental exposures. So in those earlier articles, “we would probably write the discussion section differently now,” said Corinne Keet, MD, PhD, first author on the 2011 milk study and an associate professor of pediatrics at Johns Hopkins University, Baltimore.

Indeed, “when you compare [SLIT] to Palforzia or other studies of low-dose OIT (300 mg/d), they look equal in terms of their efficacy,” said senior author Robert Wood, MD, professor of pediatrics and director of pediatric allergy and immunology at Johns Hopkins. Yet, “I’m afraid we had a major [negative] impact on pharma’s interest in pursuing SLIT.”

Without corporate funding, it’s nearly impossible to conduct the large, multisite trials required for FDA approval of a treatment. And without approved products, many allergists are reluctant to offer the therapy, Dr. Wood said. It “makes your life a lot more complicated to be dabbling in things that are not approved,” he noted.

But at least one company is giving it a go. Applying the SLIT principle of delivering food allergens to tolerance-promoting immune cells in the mouth, New York–based Intrommune Therapeutics recently started enrolling peanut-allergic adults for a phase 1 trial of its experimental toothpaste.

Interest in food-allergy SLIT seems to be growing. “I definitely think that it could be an option for the future,” said Jaclyn Bjelac, MD, associate director of the Food Allergy Center of Excellence at the Cleveland Clinic. “Up until a few months ago, it really wasn’t on our radar.”

On conversations with Dr. Kim, philanthropists and drug developers said they found the recent data on SLIT promising, yet pointed out that food SLIT protocols and products are already in the public domain – they are described in published research using allergen extracts that are on the market. They “can’t see a commercial path forward,” Dr. Kim said in an interview. “And that’s kind of where many of my conversations end.”

Although there are no licensed SLIT products for food allergies, between 2014 and 2017, the FDA approved four sublingual immunotherapy tablets to treat environmental allergies – Stallergenes-Greer’s Oralair and ALK’s Grastek for grass pollens, ALK’s Odactra for dust mites, and ALK’s Ragwitek for short ragweed.

SLIT tablets work as well as allergy shots (subcutaneous immunotherapy) for controlling environmental allergy symptoms, they have a better safety profile, according to AAAAI guidelines, and they can be self-administered at home, which has made them a popular option globally. “Our European colleagues have used sublingual immunotherapy much more frequently than, for example, in the U.S.,” said Kari Nadeau, MD, PhD, director of the Sean N. Parker Center for Allergy and Asthma Research at Stanford (Calif.) University.

Use of SLIT is also increasing in the United States, especially as FDA-approved products become available. In a 2019 survey, the percentage of U.S. allergists who said they were offering sublingual treatment for environmental allergies increased from 5.9% in 2007 to 73.5% in 2019. However, only 11.2% reported extensive SLIT use; the remainder reported some (50.5%) or little (38.3%) use.

As noted above, considerably fewer U.S. allergists use SLIT to treat food allergies. Similarly, a 2021 survey of allergists in Canada found that only 7% offered food sublingual immunotherapy; more than half reported offering OIT.

One practice, Allergy Associates of La Crosse (Wis.), has offered SLIT drops for food and environmental allergies for decades. Since the clinic opened in 1970, more than 200,000 people have been treated with its protocol. Every patient receives customized sublingual drops – “exactly what they’re allergic to, exactly how allergic they are, and then we build from there,” said Jeff Kessler, MBA, FACHE, practice executive at Allergy Associates of La Crosse. “Quite frankly, it’s the way immunotherapy should be done.

Over the years, endpoints for food allergy treatment trials have shifted from enabling patients to eat a full serving of their allergen to merely raising their threshold to guard against accidental exposures. So in those earlier articles, “we would probably write the discussion section differently now,” said Corinne Keet, MD, PhD, first author on the 2011 milk study and an associate professor of pediatrics at Johns Hopkins University, Baltimore.

Indeed, “when you compare [SLIT] to Palforzia or other studies of low-dose OIT (300 mg/d), they look equal in terms of their efficacy,” said senior author Robert Wood, MD, professor of pediatrics and director of pediatric allergy and immunology at Johns Hopkins. Yet, “I’m afraid we had a major [negative] impact on pharma’s interest in pursuing SLIT.”

Without corporate funding, it’s nearly impossible to conduct the large, multisite trials required for FDA approval of a treatment. And without approved products, many allergists are reluctant to offer the therapy, Dr. Wood said. It “makes your life a lot more complicated to be dabbling in things that are not approved,” he noted.

But at least one company is giving it a go. Applying the SLIT principle of delivering food allergens to tolerance-promoting immune cells in the mouth, New York–based Intrommune Therapeutics recently started enrolling peanut-allergic adults for a phase 1 trial of its experimental toothpaste.

Interest in food-allergy SLIT seems to be growing. “I definitely think that it could be an option for the future,” said Jaclyn Bjelac, MD, associate director of the Food Allergy Center of Excellence at the Cleveland Clinic. “Up until a few months ago, it really wasn’t on our radar.”

On conversations with Dr. Kim, philanthropists and drug developers said they found the recent data on SLIT promising, yet pointed out that food SLIT protocols and products are already in the public domain – they are described in published research using allergen extracts that are on the market. They “can’t see a commercial path forward,” Dr. Kim said in an interview. “And that’s kind of where many of my conversations end.”

Although there are no licensed SLIT products for food allergies, between 2014 and 2017, the FDA approved four sublingual immunotherapy tablets to treat environmental allergies – Stallergenes-Greer’s Oralair and ALK’s Grastek for grass pollens, ALK’s Odactra for dust mites, and ALK’s Ragwitek for short ragweed.

SLIT tablets work as well as allergy shots (subcutaneous immunotherapy) for controlling environmental allergy symptoms, they have a better safety profile, according to AAAAI guidelines, and they can be self-administered at home, which has made them a popular option globally. “Our European colleagues have used sublingual immunotherapy much more frequently than, for example, in the U.S.,” said Kari Nadeau, MD, PhD, director of the Sean N. Parker Center for Allergy and Asthma Research at Stanford (Calif.) University.

Use of SLIT is also increasing in the United States, especially as FDA-approved products become available. In a 2019 survey, the percentage of U.S. allergists who said they were offering sublingual treatment for environmental allergies increased from 5.9% in 2007 to 73.5% in 2019. However, only 11.2% reported extensive SLIT use; the remainder reported some (50.5%) or little (38.3%) use.

As noted above, considerably fewer U.S. allergists use SLIT to treat food allergies. Similarly, a 2021 survey of allergists in Canada found that only 7% offered food sublingual immunotherapy; more than half reported offering OIT.

One practice, Allergy Associates of La Crosse (Wis.), has offered SLIT drops for food and environmental allergies for decades. Since the clinic opened in 1970, more than 200,000 people have been treated with its protocol. Every patient receives customized sublingual drops – “exactly what they’re allergic to, exactly how allergic they are, and then we build from there,” said Jeff Kessler, MBA, FACHE, practice executive at Allergy Associates of La Crosse. “Quite frankly, it’s the way immunotherapy should be done.

Just when you start wondering what crazy and potentially dangerous thing people can do to themselves next, comes a crazy and potentially dangerous new trend. The good folks at TikTok have provided patients a new treatment for stuffed up sinuses.

Dangerous? Well, that’s what doctors say, anyway.

“We typically do not recommend putting anything into the nostril for the obvious fact that it could get dislodged or lodged up into the nasal cavity,” Anthony Del Signore, MD, of Mount Sinai Union Square, New York, told TODAY.

“Not only does it have the potential to rot or cause a nasal obstruction, it can induce an episode of sinusitis,” Omid Mehdizadeh, MD, of Providence Saint John’s Health Center, Santa Monica, Calif., explained to Shape.

But who doesn't want to breathe easier and keep blood-sucking vampires at bay?

Seeing faces in random places?

Ever look up at the clouds, at a fast-moving train, or into your morning bowl of cereal and see two eyes, a nose, and a mouth looking back at you? You may shake it off and think you’re imagining something, but it's actually your brain doing what it’s built to do and researchers know why.

The phenomenon is called face pareidolia, and it’s technically an error function of the human brain. Evolution has molded our brains to rapidly identify faces, according to David Alais, PhD, of the University of Sydney, Australia, lead author of the study.

“But the system plays ‘fast and loose’ by applying a crude template of two eyes over a nose and mouth. Lots of things can satisfy that template and thus trigger a face detection response,” he said in a separate statement. But not only are we seeing faces, our brains go one step further and seemingly give those faces feelings.

Corporate dream manipulation

Advertisements are quite literally everywhere. On billboards, in commercials, in videos, in movies; the list goes on and on. Still, at least you can shut your eyes and be mercifully free of corporate interference inside your own head, right? Right?

Early in 2021, Coors launched an ad campaign that seemed to be a b bit of a gimmick, if not a joke. Coors claimed that if people watched an ad before bed, and played an 8-hour soundscape while sleeping, their dreams would be filled with crisp mountains and cold, thirst-quenching beverages. While, the Coors campaign didn’t go viral, someone was paying attention. A group of 35 leading researchers published an open letter on the subject of corporate dream manipulation, in the journal Dream Engineering.

"Multiple marketing studies are openly testing new ways to alter and motivate purchasing behavior through dream and sleep hacking. The commercial, for-profit use of dream incubation is rapidly becoming a reality," wrote the investigators. "As sleep and dream researchers, we are deeply concerned about marketing plans aimed at generating profits at the cost of interfering with our natural nocturnal memory processing."

People have tried to manipulate their dreams for countless years, but only in recent years have scientists attempted to target or manipulate behavior through dreams. In a 2014 study, smokers exposed to tobacco smoke and rotten egg smell while sleeping reduced their cigarette consumption by 30%.

Got breast milk?

As we know, breast milk has endless benefits for newbords and babies, but many things can stand in the way of a mother’s ability to breastfeed. Baby formula has served as a good enough substitute. But now, there might be something that’s even better.

A start-up company called BIOMILQ created a product that could be groundbreaking. Using “breakthrough mammary biotechnology,” BIOMILQ created cell-cultured breast milk.

Postpartum depression isn’t just something new mothers can get. Turns out it can affect new fathers, too, according to a new study.

Michael W., a 38-year-old New Jersey–based attorney, and his wife had been excitedly planning for the birth of their baby and were overjoyed when she was born.

But after that, “I found that parenting a newborn was shockingly exhausting. I felt unprepared for the task, overwhelmed by the burden of the 24-hour-schedule and lack of sleep, and I struggled with feelings of inadequacy,” he said in an interview.

Michael never thought he had postpartum depression (PPD), perhaps because the condition is more commonly associated with women. But a study published in the American Journal of Men’s Health suggests that PPD also affects men.

A team of Danish investigators led by researcher Sarah Pedersen, of the department of public health, Aarhus University, extensively interviewed eight fathers with PPD and found their primary experiences involved feelings of being overwhelmed and powerless or inadequate, which sometimes turned into anger and frustration.

“I think one of the most important take-home messages is that practicing clinicians working with new parents should invite fathers to your consultations and engage the fathers as much as possible,” Ms. Pedersen said in an interview.

The findings also contained a message for parents, she says.

“I hope you will support each other and talk about your feelings and how you experience the transition to parenthood – know that it will take time to adjust to your new role,” she said.
 

Not enough attention

There’s been too little focus on fathers when it comes to PPD, according to Ms. Pedersen.

“During the last decade, several studies have examined the prevalence of PPD in men, and there is rising evidence that paternal PPD is associated with increased risk of long-term adverse behavioral and emotional outcomes in children,” she said.

Nevertheless, only three studies have been based on interviews with fathers who had personal experience with PPD.

“The purpose of our study was, first of all, to explore the lived experience of fathers who had PPD and, secondly, to gain deeper understanding of their help-seeking behavior – barriers to seeking help and facilitators of help-seeking,” Ms. Pedersen said.

The study was based on “semistructured” interviews with eight Danish fathers (ages 29-38 years) who had had PPD, none of whom had a previous history of depression.

All of them had received a formal diagnosis of PPD by a general practitioner or psychologist, and all had sought or received mental health care and considered themselves recovered from depression at the time of the interview.

The researchers used a technique called interpretative phenomenological analysis to analyze the interviews.

This method “aims to produce in-depth examinations of certain phenomena by examining how individuals make meaning of their own life experiences,” the authors wrote.
 

A ‘radical change’

Of the fathers, five described the period of pregnancy as a “time of happiness, full of positive expectations about fatherhood.”

But “the fathers’ great expectations were later replaced by a very different reality of fatherhood,” the authors wrote, noting that the transition to fatherhood was, in the words of one participant, a “radical change that you just can’t imagine.”

Most fathers expressed a feeling of being overwhelmed, and three felt unready for the task, which added to their depression.

“The participants wanted to be emotionally and physically present in their child’s life, but during the time of their depression, these kind-hearted intentions changed into feelings of guilt and inadequacy, as the participants did not feel they had enough energy and mental strength to become the kind of fathers they wanted to be,” the authors wrote.

The fathers mentioned stressors they believed contributed to their PPD, including complications during their partners’ pregnancies, unplanned cesarean birth (three fathers), the partners’ difficulties with breastfeeding (five fathers), and employment-related concerns. Five reported that their partners had postpartum emotional distress.
 

‘Masculine norms’

A second focus of the research was to examine fathers’ help-seeking behaviors, Ms. Pedersen said.

Ultimately, all the men sought formal help, either from their general practitioners or from a health visitor, with two seeking help right after birth.

Although the men were able to recognize changes in mood and behavior in retrospect, many did not regard them as signs of depression before their diagnosis.

Most had heard of PPD, but primarily as it affects women. Three sought information online about paternal PPD but couldn’t find any.

Four participants described experiencing PPD as “taboo,” based on a “combination of false beliefs, stigma, and masculine norms,” the authors stated, since men “are supposed to be big and strong and take care of everything, and suddenly you can’t.”

The authors reported that seven participants were screened for PPD or depression by a health care professional.

“The screening was an important part of the help-seeking process, as this was the first time two of the fathers were introduced to PPD,” the authors noted.

Although the screening “had the potential to spark conversation” about PPD, it was geared toward women, and some participants did not feel it was relevant to them.

“Future research should focus on identification of educational needs about paternal PPD among both parents, health care professionals, and other professionals taking care of new families,” Ms. Pedersen said.

Michael W. says it would have been helpful if someone had prepared him and his wife for what to expect, or if there had been some type of screening. Also, he advises expectant parents to “get some real-life experience by spending time around a newborn to see what’s involved.”
 

Different symptoms

“We often talk about mothers suffering from PPD, so it is more normalized for mothers to bring it up or for loved ones to ask mothers about how they are doing physically and psychologically after the birth,” Craig Garfield, MD, an attending physician and founder/director of Family and Child Health innovations at Ann and Robert H. Lurie Children’s Hospital, Chicago, said in an interview.

For fathers, “it is not discussed as commonly, so friends and families don’t often ask dads, and dads don’t know where to turn,” said Dr. Garfield, professor of pediatrics and medical social sciences at Northwestern University, Chicago. He was not involved with the study.

He noted that symptoms in fathers might differ from those of mothers.

“I have seen fathers who are anxious or more moody than they had been prior, or more angry, and I have seen fathers who throw themselves into work or begin drinking more – all related to changes in mood and depressive symptoms in the postnatal period,” he said.

Symptoms in men may last longer than in women. Dr. Garfield’s group published a study in which they surveyed 400 mothers and fathers of premature infants in the neonatal intensive care unit (NICU) about depressive symptoms around the time of NICU admission, at discharge home, and then after 30 days at home.

Roughly one-third of mothers screened positive for depressive symptoms around NICU admission, as did 17% of fathers. But the mothers’ depression scores improved by discharge and 30 days after being home, while the fathers’ remained “essentially unchanged,” he said.

“Further, we found that if doctors were to screen mothers and fathers during the NICU stay – at admission or even at discharge – that would greatly improve their ability to predict who would still have depressive symptoms 1 month after going home.”

Ms. Pedersen agrees that clinicians should incorporate screening for PPD into their practices and be proactive in encouraging fathers to get help.

“Keep pushing,” she advised, as “men rarely seek help, compared to women, in matters of mental health.”

Although the screening “had the potential to spark conversation” about PPD, it was geared toward women, and some participants did not feel it was relevant to them.

“Future research should focus on identification of educational needs about paternal PPD among both parents, health care professionals, and other professionals taking care of new families,” Ms. Pedersen said.

Michael W. says it would have been helpful if someone had prepared him and his wife for what to expect, or if there had been some type of screening. Also, he advises expectant parents to “get some real-life experience by spending time around a newborn to see what’s involved.”
 

Different symptoms

“We often talk about mothers suffering from PPD, so it is more normalized for mothers to bring it up or for loved ones to ask mothers about how they are doing physically and psychologically after the birth,” Craig Garfield, MD, an attending physician and founder/director of Family and Child Health innovations at Ann and Robert H. Lurie Children’s Hospital, Chicago, said in an interview.

For fathers, “it is not discussed as commonly, so friends and families don’t often ask dads, and dads don’t know where to turn,” said Dr. Garfield, professor of pediatrics and medical social sciences at Northwestern University, Chicago. He was not involved with the study.

He noted that symptoms in fathers might differ from those of mothers.

“I have seen fathers who are anxious or more moody than they had been prior, or more angry, and I have seen fathers who throw themselves into work or begin drinking more – all related to changes in mood and depressive symptoms in the postnatal period,” he said.

Symptoms in men may last longer than in women. Dr. Garfield’s group published a study in which they surveyed 400 mothers and fathers of premature infants in the neonatal intensive care unit (NICU) about depressive symptoms around the time of NICU admission, at discharge home, and then after 30 days at home.

Roughly one-third of mothers screened positive for depressive symptoms around NICU admission, as did 17% of fathers. But the mothers’ depression scores improved by discharge and 30 days after being home, while the fathers’ remained “essentially unchanged,” he said.

“Further, we found that if doctors were to screen mothers and fathers during the NICU stay – at admission or even at discharge – that would greatly improve their ability to predict who would still have depressive symptoms 1 month after going home.”

Ms. Pedersen agrees that clinicians should incorporate screening for PPD into their practices and be proactive in encouraging fathers to get help.

“Keep pushing,” she advised, as “men rarely seek help, compared to women, in matters of mental health.”

The stark realities of antimicrobial resistance – including rising rates of difficult-to-treat infections, lack of a robust pipeline of future antimicrobials, and COVID-19 treatments that leave people more vulnerable to infections – remain urgent priorities, experts say.

For some patients, the pandemic and antimicrobial resistance (AMR) are intertwined.

“One patient I’m seeing now in service really underscores how the two interact,” Vance Fowler, MD, said during a June 30 media briefing sponsored by the Infectious Diseases Society of America (IDSA). A man in his mid-40s, married with a small child, developed COVID-19 in early January 2021. He was intubated, spent about 1 month in the ICU, and managed to survive.

“But since then he has been struck with a series of progressively more drug resistant bacteria,” said Dr. Fowler, professor of medicine at Duke University, Durham, N.C., and chair of the IDSA Antimicrobial Resistance Committee.

The patient acquired Pseudomonas ventilator-associated pneumonia. Although the infection initially responded to standard antibiotics, he has experienced relapses over the past few months. Through these multiple infections the Pseudomonas grew increasingly pan-resistant to treatment.

The only remaining antimicrobial agent for this patient, Dr. Fowler said, is “a case study in what we are describing ... a drug that is used relatively infrequently, that is fairly expensive, but for that particular patient is absolutely vital.”
 

A ‘terrifying’ personal experience

Tori Kinamon, a Duke University medical student and Food and Drug Administration antibacterial drug resistance fellow, joined Dr. Fowler at the IDSA briefing. She shared her personal journey of surviving a methicillin-resistant Staphylococcus aureus (MRSA) infection, one that sparked her interest in becoming a physician.

“I had a very frightening and unexpected confrontation with antimicrobial resistance when I was a freshman in college,” Ms. Kinamon said.

A few days after competing in a Division One gymnastics championship, she felt a gradual onset of pain in her left hamstring. The pain grew acutely worse and, within days, her leg become red, swollen, and painful to the touch.

Ms. Kinamon was admitted to the hospital for suspected cellulitis and put on intravenous antibiotics.

“However, my clinical condition continued to decline,” she recalled. “Imaging studies revealed a 15-cm abscess deep in my hamstring.”

The limb- and life-threatening infection left her wondering if she would come out of surgery with both legs.

“Ultimately, I had eight surgeries in 2 weeks,” she said.

“As a 19-year-old collegiate athlete, that’s terrifying. And I never imagined that something like that would happen to me – until it did,” said Ms. Kinamon, who is an NCAA infection prevention advocate.

When Ms. Kinamon’s kidneys could no longer tolerate vancomycin, she was switched to daptomycin.

“I reflect quite frequently on how having that one extra drug in the stockpile had a significant impact on my outcome,” she said.
 

Incentivizing new antimicrobial agents

A lack of new antimicrobials in development is not a new story.

“There’s been a chill that’s been sustained on the antibiotic development field. Most large pharmaceutical companies have left the area of anti-infectants and the bulk of research and development is now in small pharmaceutical companies,” Dr. Fowler said. “And they’re struggling.”

One potential solution is the Pasteur Act, a bipartisan bill reintroduced in Congress and supported by IDSA. The bill encourages pharmaceutical companies to develop new antimicrobial agents with funding not linked to sales or use of the drugs.

Furthermore, the bill emphasizes appropriate use of these agents through effective stewardship programs.

Although some institutions shifted resources away from AMR out of necessity when COVID-19 struck, “I can say certainly from our experience at Duke that at least stewardship was alive and well. It was not relegated to the side,” Dr. Fowler said.

“In fact,” he added, “if anything, COVID really emphasized the importance of stewardship” by helping clinicians with guidance on the use of remdesivir and other antivirals during the pandemic.

Also, in some instances, treatments used to keep people with COVID-19 alive can paradoxically place them at higher risk for other infections, Dr. Fowler said, citing corticosteroids as an example.
 

Everyone’s concern

AMR isn’t just an issue in hospital settings, either. Ms. Kinamon reiterated that she picked up the infection in an athletic environment.

“Antimicrobial resistance is not just a problem for ICU patients in the hospital. I was the healthiest I had ever been and just very nearly escaped death due to one of these infections,” she said. ”As rates of resistance rise as these pathogens become more virulent, AMR is becoming more and more of a community threat,” she added.

Furthermore, consumers are partially to blame as well, Dr. Fowler noted.

“It’s interesting when you look at the surveys of the numbers of patients that have used someone else’s antibiotics” or leftover antimicrobial agents from a prior infection.

“It’s really startling ... that’s the sort of antibiotic overuse that directly contributes to antibacterial resistance,” he said.
 

Reasons for optimism

Promising advances in diagnostics, treatment, and prevention of AMRs are underway, Dr. Fowler said.

“It always gets me really excited to talk about it. It’s amazing what technology and scientific discovery can bring to this discussion and to this threat,” he said.

For example, there is a “silent revolution” in diagnostics with the aim to rapidly provide life-saving actionable data on a real patient in nearly real time.

Traditionally, “you start off by treating what should be there” while awaiting results of tests to narrow down therapy, Dr. Fowler said. However, a whole host of new platforms are in development to reduce the time to susceptibility results. This kind of technology has “the potential to transform our ability to take care of patients, giving them the right drug at the right time and no more,” he said.

Another promising avenue of research involves bacteriophages. Dr. Fowler is principal investigator on a clinical trial underway to evaluate bacteriophages as adjunct therapy for MRSA bacteremia.

When it comes to prevention on AMR infections in the future, “I continue to be optimistic about the possibility of vaccines to prevent many of these infections,” Dr. Fowler said, adding that companies are working on vaccines against these kinds of infections caused by MRSA or Escherichia coli, for example.
 

Patient outcomes

The man in his 40s with the multidrug resistant Pseudomonas infections “is now to the point where he’s walking in the halls and I think he’ll get out of the hospital eventually,” Dr. Fowler said.

“But his life is forever changed,” he added.

Ms. Kinamon’s recovery from MRSA included time in the ICU, 1 month in a regular hospital setting, and 5 months at home.

“It sparked my interest in antibiotic research and development because I see myself as a direct beneficiary of the stockpile of antibiotics that were available to treat my infection,” Ms. Kinamon said. “Now as a medical student working with patients who have similar infections, I feel a deep empathy and connectedness to them because they ask the same questions that I did.”

Adults with sickle cell disease who experienced a vaso-occlusive crisis had substantially better outcomes when they were treated at specialty infusion centers than those treated in emergency departments (EDs), a prospective observational study shows.

At infusion centers, patients received pain medication an average of 70 minutes faster compared with patients treated in EDs (62 vs. 132 minutes), according to a study published online in the Annals of Internal Medicine. In addition, patients at infusion centers were 3.8 times more likely to have their pain reassessed within 30 minutes of the first dose. And they were 4 times more likely to be discharged home, the researchers found.

“It’s not that the emergency room doctors don’t want to do the right thing,” study author Sophie Lanzkron, MD, said in an interview. “They do, but they aren’t experts in sickle cell disease. They work in an emergency room, which is an incredibly busy, stressful place where they see trauma and heart attacks and strokes and all of these things that need emergency care. And so it just is not the right setting to treat people with sickle cell disease.”

To assess whether care at specialty infusion centers or EDs leads to better outcomes for patients with sickle cell disease with uncomplicated vaso-occlusive crises, Dr. Lanzkron, director of the Sickle Cell Center for Adults at the Johns Hopkins Hospital, Baltimore, and colleagues conducted the ESCAPED (Examining Sickle Cell Acute Pain in the Emergency vs. Day Hospital) study.

The trial included 483 adults with sickle cell disease who lived within 60 miles of an infusion center in four U.S. cities: Baltimore, Maryland; Cleveland, Ohio; Milwaukee, Wisconsin; and Baton Rouge, Louisiana. Investigators recruited patients between April 2015 and December 2016 and followed them for 18 months after enrollment.

The present analysis focused on data from 269 participants who had infusion center visits or ED visits that occurred during weekdays when infusion centers were open. Two sites had infusion centers solely for adults with sickle cell disease (Baltimore and Milwaukee), and two infusion centers shared infusion space with other hematology-oncology patients. All four sites were in hospitals that also had EDs. 

Although participants may have received comprehensive care at one of the sites with an infusion center, those who lived farther from an infusion center were likely to receive care for acute pain at an ED closer to home, the authors explain in the article.

The investigators used propensity score methodology to balance patient characteristics in the study groups.
 

Quick, effective pain reduction is beneficial

The results suggest that infusion centers “are more likely to provide guideline-based care than EDs,” and this care “can improve overall outcomes,” the authors write. 

Although the specialty infusion centers the researchers studied used various models, similar outcomes were seen at all of them.

The study did not include patients who had complications of sickle cell disease in addition to vaso-occlusive crisis, the researchers note. 

“[Because] the magnitude of the treatment effects estimated in our study is large and we have captured most of the important potential confounders, an unmeasured confounder that can nullify the treatment effect is unlikely to exist,” the authors write. 

“Sickle cell disease is a complicated condition that affects multiple organs. Patients who present with acute pain will have better outcomes being treated under providers who know and understand the disease,” commented Julie Kanter, MD, director of the adult sickle cell disease program and codirector of the Comprehensive Sickle Cell Center at the University of Alabama at Birmingham. “Specialized infusion centers offer the opportunity to both improve outcomes and decrease the cost of care. Most importantly, it is better for the individual with sickle cell disease,” she said.

Dr. Kanter wrote an accompanying editorial about the ESCAPED findings. The editorialist notes that “opioid medications are the only option to reduce the pain caused by microvascular injury” in patients with sickle cell crisis, although these treatments do not reduce the underlying damage and have substantial side effects and risks. Nevertheless, “quick and effective reduction of pain can allow patients to more easily move, stretch, and breathe ... important to increase oxygenation and restore blood flow, which will eventually abate the crisis,” Dr. Kanter wrote. 

The study shows that the infusion center treatment approach can benefit patients across different settings, commented John J. Strouse, MD, PhD, medical director of the adult sickle cell program at Duke University Sickle Cell Center, Durham, N.C., who was not involved in the study. 

“They show that they can definitely get closer to the recommendations of guidelines for acute pain management and sickle cell disease” in a setting that is focused on one problem, he said. “The other piece that is really important is that people are much more likely to go home if you follow the guideline.”
 

Infusion centers are scarce

“These systems need to be built,” Dr. Lanzkron said. “In most places, patients don’t have access to the infusion center model for their care. And in some places, it is not going to be practical.” Still, there may be ways to establish infusion locations, such as at oncology centers. And while there are challenges to delivering sickle cell disease care in EDs, “emergency rooms need to try to meet the needs of this patient population as best as they can,” Dr. Lanzkron said.

“Structural racism has played a role in the quality of care delivered” to patients with sickle cell disease, Dr. Lanzkron said. “The big message is [that] there is a better way to do this.” 

The study was funded by the Patient-Centered Outcomes Research Institute. Dr. Lanzkron’s disclosures included grants or contracts with government agencies and companies that are paid to her institution, as well as consulting fees from Bluebird Bio, Novo Nordisk, and Pfizer. Coauthors have disclosed working with sickle cell organizations and various medical companies. Dr. Kanter and Dr. Strouse have reported no relevant financial relationships.

At infusion centers, patients received pain medication an average of 70 minutes faster compared with patients treated in EDs (62 vs. 132 minutes), according to a study published online in the Annals of Internal Medicine. In addition, patients at infusion centers were 3.8 times more likely to have their pain reassessed within 30 minutes of the first dose. And they were 4 times more likely to be discharged home, the researchers found.

“It’s not that the emergency room doctors don’t want to do the right thing,” study author Sophie Lanzkron, MD, said in an interview. “They do, but they aren’t experts in sickle cell disease. They work in an emergency room, which is an incredibly busy, stressful place where they see trauma and heart attacks and strokes and all of these things that need emergency care. And so it just is not the right setting to treat people with sickle cell disease.”

To assess whether care at specialty infusion centers or EDs leads to better outcomes for patients with sickle cell disease with uncomplicated vaso-occlusive crises, Dr. Lanzkron, director of the Sickle Cell Center for Adults at the Johns Hopkins Hospital, Baltimore, and colleagues conducted the ESCAPED (Examining Sickle Cell Acute Pain in the Emergency vs. Day Hospital) study.

The trial included 483 adults with sickle cell disease who lived within 60 miles of an infusion center in four U.S. cities: Baltimore, Maryland; Cleveland, Ohio; Milwaukee, Wisconsin; and Baton Rouge, Louisiana. Investigators recruited patients between April 2015 and December 2016 and followed them for 18 months after enrollment.

The present analysis focused on data from 269 participants who had infusion center visits or ED visits that occurred during weekdays when infusion centers were open. Two sites had infusion centers solely for adults with sickle cell disease (Baltimore and Milwaukee), and two infusion centers shared infusion space with other hematology-oncology patients. All four sites were in hospitals that also had EDs. 

Although participants may have received comprehensive care at one of the sites with an infusion center, those who lived farther from an infusion center were likely to receive care for acute pain at an ED closer to home, the authors explain in the article.

The investigators used propensity score methodology to balance patient characteristics in the study groups.
 

Quick, effective pain reduction is beneficial

The results suggest that infusion centers “are more likely to provide guideline-based care than EDs,” and this care “can improve overall outcomes,” the authors write. 

Although the specialty infusion centers the researchers studied used various models, similar outcomes were seen at all of them.

The study did not include patients who had complications of sickle cell disease in addition to vaso-occlusive crisis, the researchers note. 

“[Because] the magnitude of the treatment effects estimated in our study is large and we have captured most of the important potential confounders, an unmeasured confounder that can nullify the treatment effect is unlikely to exist,” the authors write. 

“Sickle cell disease is a complicated condition that affects multiple organs. Patients who present with acute pain will have better outcomes being treated under providers who know and understand the disease,” commented Julie Kanter, MD, director of the adult sickle cell disease program and codirector of the Comprehensive Sickle Cell Center at the University of Alabama at Birmingham. “Specialized infusion centers offer the opportunity to both improve outcomes and decrease the cost of care. Most importantly, it is better for the individual with sickle cell disease,” she said.

Dr. Kanter wrote an accompanying editorial about the ESCAPED findings. The editorialist notes that “opioid medications are the only option to reduce the pain caused by microvascular injury” in patients with sickle cell crisis, although these treatments do not reduce the underlying damage and have substantial side effects and risks. Nevertheless, “quick and effective reduction of pain can allow patients to more easily move, stretch, and breathe ... important to increase oxygenation and restore blood flow, which will eventually abate the crisis,” Dr. Kanter wrote. 

The study shows that the infusion center treatment approach can benefit patients across different settings, commented John J. Strouse, MD, PhD, medical director of the adult sickle cell program at Duke University Sickle Cell Center, Durham, N.C., who was not involved in the study. 

“They show that they can definitely get closer to the recommendations of guidelines for acute pain management and sickle cell disease” in a setting that is focused on one problem, he said. “The other piece that is really important is that people are much more likely to go home if you follow the guideline.”
 

Infusion centers are scarce

“These systems need to be built,” Dr. Lanzkron said. “In most places, patients don’t have access to the infusion center model for their care. And in some places, it is not going to be practical.” Still, there may be ways to establish infusion locations, such as at oncology centers. And while there are challenges to delivering sickle cell disease care in EDs, “emergency rooms need to try to meet the needs of this patient population as best as they can,” Dr. Lanzkron said.

“Structural racism has played a role in the quality of care delivered” to patients with sickle cell disease, Dr. Lanzkron said. “The big message is [that] there is a better way to do this.” 

The study was funded by the Patient-Centered Outcomes Research Institute. Dr. Lanzkron’s disclosures included grants or contracts with government agencies and companies that are paid to her institution, as well as consulting fees from Bluebird Bio, Novo Nordisk, and Pfizer. Coauthors have disclosed working with sickle cell organizations and various medical companies. Dr. Kanter and Dr. Strouse have reported no relevant financial relationships.

Older adults with hearing impairment tend to have poorer physical function, less walking endurance, and faster declines in physical function compared with older adults with normal hearing, according to a study published online in JAMA Network Open.

Hearing loss is associated with slower gait and, in particular, worse balance, the data suggest.

“Because hearing impairment is amenable to prevention and management, it potentially serves as a target for interventions to slow physical decline with aging,” the researchers said.

To examine how hearing impairment relates to physical function in older adults, Pablo Martinez-Amezcua, MD, PhD, MHS, a researcher in the department of epidemiology at Johns Hopkins University, Baltimore, and colleagues analyzed data from the ongoing Atherosclerosis Risk in Communities (ARIC) study.

ARIC initially enrolled more than 15,000 adults in Maryland, Minnesota, Mississippi, and North Carolina between 1987 and 1989. In the present study, the researchers focused on data from 2,956 participants who attended a study visit between 2016 and 2017, during which researchers assessed their hearing using pure tone audiometry.

Hearing-study participants had an average age of 79 years, about 58% were women, and 80% were White. Approximately 33% of the participants had normal hearing, 40% had mild hearing impairment, 23% had moderate hearing impairment, and 4% had severe hearing impairment.

Participants had also undergone assessment of physical functioning at study visits between 2011 and 2019, including a fast-paced 2-minute walk test to measure their walking endurance. Another assessment, the Short Physical Performance Battery (SPPB), tests balance, gait speed, and chair stands (seated participants stand up and sit back down five times as quickly as possible while their arms are crossed).

Dr. Martinez-Amezcua and colleagues found that severe hearing impairment was associated with a lower average SPPB score compared with normal hearing in a regression analysis. Specifically, compared with those with normal hearing, participants with severe hearing impairment were more likely to have low scores on the SPPB (odds ratio, 2.72), balance (OR, 2.72), and gait speed (OR, 2.16).

However, hearing impairment was not significantly associated with the chair stand test results. The researchers note that chair stands may rely more on strength, whereas balance and gait speed may rely more on coordination and movement.

The team also found that people with worse hearing tended to walk a shorter distance during the 2-minute walk test. Compared with participants with normal hearing, participants with moderate hearing impairment walked 2.81 meters less and those with severe hearing impairment walked 5.31 meters less on average, after adjustment for variables including age, sex, and health conditions.

Participants with hearing impairment also tended to have faster declines in physical function over time.

Various mechanisms could explain associations between hearing and physical function, the authors said. For example, an underlying condition such as cardiovascular disease might affect both hearing and physical function. Damage to the inner ear could affect vestibular and auditory systems at the same time. In addition, hearing impairment may relate to cognition, depression, or social isolation, which could influence physical activity.

“Age-related hearing loss is traditionally seen as a barrier for communication,” Dr. Martinez-Amezcua told this news organization. “In the past decade, research on the consequences of hearing loss has identified it as a risk factor for cognitive decline and dementia. Our findings contribute to our understanding of other negative outcomes associated with hearing loss.”

Randomized clinical trials are the best way to assess whether addressing hearing loss might improve physical function, Dr. Martinez-Amezcua said. “Currently there is one clinical trial (ACHIEVE) that will, among other outcomes, study the impact of hearing aids on cognitive and physical function,” he said.

Although interventions may not reverse hearing loss, hearing rehabilitation strategies, including hearing aids and cochlear implants, may help, he added. Educating caregivers and changing a person’s environment can also reduce the effects hearing loss has on daily life, Dr. Martinez-Amezcua said.

“We rely so much in our sense of vision for activities of daily living that we tend to underestimate how important hearing is, and the consequences of hearing loss go beyond having trouble communicating with someone,” he said.

This study and prior research “raise the intriguing idea that hearing may provide essential information to the neural circuits underpinning movement in our environment and that correction for hearing loss may help promote physical well-being,” Willa D. Brenowitz, PhD, MPH, and Margaret I. Wallhagen, PhD, GNP-BC, both at the University of California, San Francisco, wrote in an accompanying commentary. “While this hypothesis is appealing and warrants further investigation, there are multiple other potential explanations of such an association, including potential sources of bias that may affect observational studies such as this one.”

Beyond treating hearing loss, interventions such as physical therapy or tai chi may benefit patients, they suggested.

Because many changes occur during older age, it can be difficult to understand which factor is influencing another, Dr. Brenowitz said in an interview. There are potentially relevant mechanisms through which hearing could affect cognition and physical functioning. Still another explanation could be that some people are “aging in a faster way” than others, Dr. Brenowitz said.

Dr. Lin also disclosed personal fees from Frequency Therapeutics and Caption Call. One author serves on a scientific advisory board for Shoebox and Good Machine Studio.

Dr. Wallhagen has served on the board of trustees of the Hearing Loss Association of America and is a member of the board of the Hearing Loss Association of America–California. Dr. Wallhagen also received funding for a pilot project on the impact of hearing loss on communication in the context of chronic serious illness from the National Palliative Care Research Center outside the submitted work.
