Jackie Dishner hasn’t been the same since June 2020, when COVID-19 robbed her of her energy level, ability to think clearly, and sense of taste and smell. Yet at 58, the Arizona writer is in no hurry to get the latest vaccine booster. “I just don’t want to risk getting any sicker,” she said.

Ms. Dishner has had two doses of vaccine plus two boosters. Each time, she had what regulators consider to be mild reactions, including a sore arm, slight fever, nausea, and body aches. Still, there’s some evidence that the newest booster, which protects against some of the later variants, could help people like Ms. Dishner in several ways, said Ziyad Al-Aly, MD, a clinical epidemiologist and prolific long COVID researcher at Washington University in St. Louis.

“A bivalent booster might actually [help with] your long COVID,” he said.

There may be other benefits. “What vaccines or current vaccine boosters do is reduce your risk of progression to severe COVID-19 illness,” Dr. Al-Aly said. “You are avoiding hospital stays or even worse; you’re avoiding potentially fatal outcomes after infection. And that’s really worth it. Who wants to be in the hospital this Christmas holiday?”

Each time people are infected with SARS-CoV-2, the virus that causes COVID-19, they have a fresh risk of not only getting severely ill or dying, but of developing long COVID, Dr. Al-Aly and colleagues found in a study published in Nature Medicine. “If you dodged the bullet the first time and did not get long COVID after the first infection, if you get reinfected, you’re trying your luck again,” Dr. Al-Aly said. “I would advise people not to get reinfected, which is another reason to get the booster.” 

In a recent review in The Lancet eClinicalMedicine, an international team of researchers looked at 11 studies that sought to find out if vaccines affected long COVID symptoms. Seven of those studies found that people’s symptoms improved after they were vaccinated, and four found that symptoms mostly remained the same. One found symptoms got worse in some patients. 

A study of 28,000 people published in the British Medical Journal found more evidence that vaccination may help ease symptoms. “Vaccination may contribute to a reduction in the population health burden of long COVID,” the team at the United Kingdom’s Office for National Statistics concluded. Most studies found vaccination reduced the risk of getting long COVID in the first place.

Vaccines prompt the body to produce antibodies, which stop a microbe from infecting cells. They also prompt the production of immune cells called T cells, which continue to hunt down and attack a pathogen even after infection.

A booster dose could help rev up that immune response in a patient with long COVID, said Stephen J. Thomas, MD, an infectious disease specialist at Upstate Medical Center in Syracuse, N.Y., and the center’s lead principal investigator for Pfizer/BioNTech’s COVID-19 2020 vaccine trial.

Some scientists believe long COVID might be caused when the virus persists in parts of the body where the immune system isn’t particularly active. Although they don’t fully understand the workings of the many and varied long COVID symptoms, they have a good idea about why people with long COVID often do better after receiving a vaccine or booster.

“The theory is that by boosting, the immune system may be able to ‘mop up’ those virus stragglers that have remained behind after your first cleanup attempt,” Dr. Thomas said.

“The vaccine is almost lending a hand or helping your immune response to clear that virus,” Dr. Al-Aly said.

It could be difficult for long COVID patients to make an informed decision about boosters, given the lack of studies that focus exclusively on the relationship between long COVID and boosters, according to Scott Roberts, MD, associate medical director for infection prevention at Yale New Haven (Conn.) Hospital. 

Dr. Roberts recommended that patients speak with their health care providers and read about the bivalent booster on trusted sites such as those sponsored by the Food and Drug Administration and the Centers for Disease Control and Prevention. Long COVID patients should get the latest boosters, especially as there’s no evidence they are unsafe for them. “The antibody response is appropriately boosted, and there is a decent chance this will help reduce the impact of long COVID as well,” he said. “Waiting will only increase the risk of getting infected and increase the chances of long COVID.”

Only 12% of Americans 5 years and older have received the updated booster, according to the CDC, although it’s recommended for everyone. Just over 80% of Americans have gotten at least one vaccine dose. Dr. Thomas understands why the uptake has been so low: Along with people like Ms. Dishner, who fear more side effects or worse symptoms, there are those who believe that hybrid immunity – vaccination immunity plus natural infection – is superior to vaccination alone and that they don’t need a booster.

Studies show that the bivalent boosters, which protect against older and newer variants, can target even the new, predominant COVID-19 strains. Whether that is enough to convince people in the no-booster camp who lost faith when their vaccinated peers started getting COVID-19 is unclear, although, as Dr. Al-Aly has pointed out, vaccinations help keep people from getting so sick that they wind up in the hospital. And, with most of the population having received at least one dose of vaccine, most of those getting infected will naturally come from among the vaccinated.

Thomas describes the expectation that vaccines would prevent everyone from getting sick as “one of the major fails” of the pandemic.

Counting on a vaccine to confer 100% immunity is “a very high bar,” he said. “I think that’s what people expected, and when they weren’t seeing it, they kind of said: ‘Well, what’s the point? You know, things are getting better. I’d rather take my chances than keep going and getting boosted.’ ”

One point – and it’s a critical one – is that vaccination immunity wanes. Plus new variants arise that can evade at least some of the immunity provided by vaccination. That’s why boosters are built into the COVID vaccination program.

While it’s not clear why some long COVID patients see improvements in their symptoms after being vaccinated or boosted and others do not, Dr. Al-Aly said there’s little evidence vaccines can make long COVID worse. “There are some reports out there that some people with long COVID, when they got a vaccine or booster, their symptoms got worse. You’ll read anecdotes on this side,” he said, adding that efforts to see if this is really happening have been inconclusive.

“The general consensus is that vaccines really save lives,” Dr. Al-Aly said. “Getting vaccinated, even if you are a long COVID patient, is better than not getting vaccinated.”

Eric Andrew Salata, MD, a 54-year-old internist based in Naples, Florida, made headlines 2 weeks ago when he was arrested by local police and charged with sexual battery on two of his patients, according to a police statement.

A week later, a Collier County Sheriff’s deputy found Dr. Salata’s body near his Naples home with a gunshot wound to the head, according to police. The medical examiner later ruled it a suicide.

Dr. Salata co-owned Pura Vida Medical Spa in Naples with his wife Jill Salata, a certified family nurse practitioner. They specialized in cosmetic treatment and surgery.

Naples police said that they arrested Dr. Salata after two female patients accused the doctor of allegedly drugging and raping them while they were still unconscious.

Both victims described being given nitrous oxide, also called laughing gas, for sedation and pain from the cosmetic procedure. The first victim, age 51, said Dr. Salata prescribed alprazolam (Xanax) to take before the procedure and then also gave her nitrous oxide and tequila, causing her to black out, according to NBC2 News.

The second victim, age 72, told police that as the nitrous oxide was wearing off, she found Dr. Salata performing sexual intercourse. The victim felt shocked after the sedation subsided about what had taken place, contacted police, and submitted to a sexual assault examination, according to the police statement.

At Dr. Salata’s November 22 hearing before Judge Michael Provost, a prosecutor asked the judge whether Dr. Salata should surrender his firearms; Provost reportedly dismissed the idea.

“It is disappointing and frustrating that Dr. Salata has escaped justice,” said one victim’s attorney, Adam Horowitz, in a blog post. “Yet, we are relieved that no other women will be assaulted by Dr. Salata again. It took tremendous courage for my client to tell her truth. She was ready to hold him accountable in court.”

Horowitz says he plans to file a civil lawsuit on behalf of his client against Dr. Salata’s estate. The Naples police are continuing their investigation into the victims’ cases, which now includes a third woman, said spokesman Lt. Bryan McGinn.

Meanwhile, the Pura Vida Medical Spa has closed permanently and its website has been deleted. One reviewer named Soul F. wrote on the spa’s Yelp page: “And now may God have mercy on this rapist’s soul. Amen.”

Recently the U.S. Preventive Services Task Force issued a formal recommendation that adolescents and children as young as 8 should be screened for anxiety.¹ The advice was based on a review of the research that concluded that anxiety disorders were common in youth (prevalence around 8%), screening was not overly burdensome or dangerous, and treatments were available and effective.

While pediatricians fully appreciate how common clinically significant anxiety is and its impact on the lives of youth, the reception for the recommendations have been mixed. Some are concerned that it could lead to the overprescribing of medications. Arguably, the biggest pushback, however, relates to the question of what to do when a child screens positive in a time when finding an available child and adolescent psychiatrist or other type of pediatric mental health professional can feel next to impossible. The hope of this article is to fill in some of those gaps.

Screening for anxiety disorders

The recommendations suggest using a rating scale as part of the screen but doesn’t dictate which one. A common instrument that has been employed is the Screen for Child Anxiety and Related Disorders, which is a freely available 41-item instrument that has versions for youth self-report and parent-report. A shorter 7-item rating scale, the General Anxiety Disorder–7, and the even shorter GAD-2 (the first two questions of the GAD-7), are also popular but focus, as the name applies, on general anxiety disorder and not related conditions such as social or separation anxiety that can have some different symptoms. These instruments can be given to patients and families in the waiting room or administered with the help of a nurse, physician, or embedded mental health professional. The recommendations do not include specific guidance on how often the screening should be done but repeated screenings are likely important at some interval.

Confirming the diagnosis

Of course, a screening isn’t a formal diagnosis. The American Academy of Pediatrics has expressed the view that the initial diagnosis and treatment for anxiety disorders is well within a pediatrician’s scope of practice, which means further steps are likely required beyond a referral. Fortunately, going from a positive screen to an initial diagnosis does not have to overly laborious and can focus on reviewing the DSM-5 criteria for key anxiety disorders while also ensuring that there isn’t a nonpsychiatric cause driving the symptoms, such as the often cited but rarely seen pheochromocytoma. More common rule-outs include medication-induced anxiety or substance use, excessive caffeine intake, and cardiac arrhythmias. Assessing for current and past trauma or specific causes of the anxiety such as bullying are also important.

It is important to note that it is the rule rather than the exception that youth with clinical levels of anxiety will frequently endorse a number of criteria that span multiple diagnoses including generalized anxiety disorder, social anxiety disorder, and separation anxiety disorder.² Spending a lot of effort to narrow things down to a single anxiety diagnosis often is unnecessary, as both pharmacologic and nonpharmacologic treatments don’t change all that much between individual diagnoses.
 

Explaining the diagnosis

In general, I’m a strong proponent of trying to explain any behavioral diagnoses that you make to kids in a way that is accurate but nonstigmatizing. When it comes to anxiety, one parallel I often draw is to our immune system, which most youth understand at least in basic terms. Both our immune system and our anxiety networks are natural and important; as a species, we wouldn’t have lasted long without them. Both are built to assess and respond to threats. Problems can arise, however, if the response is too strong relative to the threat or the response is activated when it doesn’t need to be. Treatment is directed not at ridding ourselves of anxiety but at helping regulate it so it works for us and not against us. Spending a few minutes going through a discussion like this can be very helpful, and perhaps more so than some dry summary of DSM-5 criteria.

Starting treatment

It is important to note that best practice recommendations when it comes to the treatment of anxiety disorder in youth do not suggest medications as the only type of treatment and often urge clinicians to try nonpharmacological interventions first.³ A specific type of psychotherapy called cognitive-behavioral therapy has the strongest scientific support as an effective treatment for anxiety but other modalities, including parenting guidance, can be helpful as well. Consequently, a referral to a good psychotherapist is paramount. For many kids, the key to overcoming anxiety is exposure: which means confronting anxiety slowly, with support, and with specific skills.

If there is a traumatic source of the anxiety, addressing that as much as possible is obviously critical and could involve working with the family or school. For some kids, this may involve frightening things they are seeing online or through other media. Finally, some health promotion activities such as exercise or mindfulness can also be quite useful.

Despite the fact that SSRIs are referred to as antidepressants, there is increasing appreciation that these medications are useful for anxiety, perhaps even more so than for mood. While only one medication, duloxetine, has Food and Drug Administration approval to treat anxiety in children as young as 7, there is good evidence to support the use of many of the most common SSRIs in treating clinical anxiety. Buspirone, beta-blockers, and antihistamine medications like hydroxyzine also can have their place in treatment, while benzodiazepines and antipsychotic medications are generally best avoided for anxious youth, especially in the primary care setting. A short but helpful medication guide with regard to pediatric anxiety has been published by the American Academy of Child and Adolescent Psychiatry.⁴

Conclusions

Clinical levels of anxiety in children and adolescents are both common and quite treatable, which has prompted new recommendations that primary care clinicians screen for them starting at age 8. While this recommendation may at first seem like yet one more task to fit in, following the guidance can be accomplished with the help of short screening tools and a managed multimodal approach to treatment.

Fortunately, going from a positive screen to an initial diagnosis does not have to overly laborious and can focus on reviewing the DSM-5 criteria for key anxiety disorders while also ensuring that there isn’t a nonpsychiatric cause driving the symptoms, such as the often cited but rarely seen pheochromocytoma. More common rule-outs include medication-induced anxiety or substance use, excessive caffeine intake, and cardiac arrhythmias. Assessing for current and past trauma or specific causes of the anxiety such as bullying are also important.

It is important to note that it is the rule rather than the exception that youth with clinical levels of anxiety will frequently endorse a number of criteria that span multiple diagnoses including generalized anxiety disorder, social anxiety disorder, and separation anxiety disorder.² Spending a lot of effort to narrow things down to a single anxiety diagnosis often is unnecessary, as both pharmacologic and nonpharmacologic treatments don’t change all that much between individual diagnoses.
 

Explaining the diagnosis

In general, I’m a strong proponent of trying to explain any behavioral diagnoses that you make to kids in a way that is accurate but nonstigmatizing. When it comes to anxiety, one parallel I often draw is to our immune system, which most youth understand at least in basic terms. Both our immune system and our anxiety networks are natural and important; as a species, we wouldn’t have lasted long without them. Both are built to assess and respond to threats. Problems can arise, however, if the response is too strong relative to the threat or the response is activated when it doesn’t need to be. Treatment is directed not at ridding ourselves of anxiety but at helping regulate it so it works for us and not against us. Spending a few minutes going through a discussion like this can be very helpful, and perhaps more so than some dry summary of DSM-5 criteria.

Starting treatment

It is important to note that best practice recommendations when it comes to the treatment of anxiety disorder in youth do not suggest medications as the only type of treatment and often urge clinicians to try nonpharmacological interventions first.³ A specific type of psychotherapy called cognitive-behavioral therapy has the strongest scientific support as an effective treatment for anxiety but other modalities, including parenting guidance, can be helpful as well. Consequently, a referral to a good psychotherapist is paramount. For many kids, the key to overcoming anxiety is exposure: which means confronting anxiety slowly, with support, and with specific skills.

If there is a traumatic source of the anxiety, addressing that as much as possible is obviously critical and could involve working with the family or school. For some kids, this may involve frightening things they are seeing online or through other media. Finally, some health promotion activities such as exercise or mindfulness can also be quite useful.

Despite the fact that SSRIs are referred to as antidepressants, there is increasing appreciation that these medications are useful for anxiety, perhaps even more so than for mood. While only one medication, duloxetine, has Food and Drug Administration approval to treat anxiety in children as young as 7, there is good evidence to support the use of many of the most common SSRIs in treating clinical anxiety. Buspirone, beta-blockers, and antihistamine medications like hydroxyzine also can have their place in treatment, while benzodiazepines and antipsychotic medications are generally best avoided for anxious youth, especially in the primary care setting. A short but helpful medication guide with regard to pediatric anxiety has been published by the American Academy of Child and Adolescent Psychiatry.⁴

Conclusions

Clinical levels of anxiety in children and adolescents are both common and quite treatable, which has prompted new recommendations that primary care clinicians screen for them starting at age 8. While this recommendation may at first seem like yet one more task to fit in, following the guidance can be accomplished with the help of short screening tools and a managed multimodal approach to treatment.

Recently the U.S. Preventive Services Task Force issued a formal recommendation that adolescents and children as young as 8 should be screened for anxiety.¹ The advice was based on a review of the research that concluded that anxiety disorders were common in youth (prevalence around 8%), screening was not overly burdensome or dangerous, and treatments were available and effective.

While pediatricians fully appreciate how common clinically significant anxiety is and its impact on the lives of youth, the reception for the recommendations have been mixed. Some are concerned that it could lead to the overprescribing of medications. Arguably, the biggest pushback, however, relates to the question of what to do when a child screens positive in a time when finding an available child and adolescent psychiatrist or other type of pediatric mental health professional can feel next to impossible. The hope of this article is to fill in some of those gaps.

Screening for anxiety disorders

The recommendations suggest using a rating scale as part of the screen but doesn’t dictate which one. A common instrument that has been employed is the Screen for Child Anxiety and Related Disorders, which is a freely available 41-item instrument that has versions for youth self-report and parent-report. A shorter 7-item rating scale, the General Anxiety Disorder–7, and the even shorter GAD-2 (the first two questions of the GAD-7), are also popular but focus, as the name applies, on general anxiety disorder and not related conditions such as social or separation anxiety that can have some different symptoms. These instruments can be given to patients and families in the waiting room or administered with the help of a nurse, physician, or embedded mental health professional. The recommendations do not include specific guidance on how often the screening should be done but repeated screenings are likely important at some interval.

Confirming the diagnosis

Of course, a screening isn’t a formal diagnosis. The American Academy of Pediatrics has expressed the view that the initial diagnosis and treatment for anxiety disorders is well within a pediatrician’s scope of practice, which means further steps are likely required beyond a referral. Fortunately, going from a positive screen to an initial diagnosis does not have to overly laborious and can focus on reviewing the DSM-5 criteria for key anxiety disorders while also ensuring that there isn’t a nonpsychiatric cause driving the symptoms, such as the often cited but rarely seen pheochromocytoma.

Bacillus Calmette-Guérin (BCG) vaccines are given to more than 100 million children every year, but there is considerable debate regarding the effectiveness of BCG vaccination in preventing tuberculosis and death, particularly among older children and adults.

The most extensive study ever conducted on the efficacy of the BCG vaccine for protection against tuberculosis, stratified by age and history of previous tuberculosis, was published in September 2022 in The Lancet Global Health. The study, which comprises a systematic review and meta-analysis, analyzed individual-level data from 26 case-contact cohort studies published over the past 20 years. The studies included data from 70,000 participants. The primary outcome was a composite of prevalent (diagnosed at or within 90 days of baseline) and incident (diagnosed more than 90 days after baseline) tuberculosis in contacts exposed to tuberculosis. Secondary outcomes were pulmonary tuberculosis, extrapulmonary tuberculosis, and mortality.

Participants were characterized as having been exposed to tuberculosis if they were reported to have been a close contact (either living in the same household or having substantial interaction outside the household) of a person with microbiologically or radiologically diagnosed pulmonary tuberculosis. Previous tuberculosis was defined as a positive interferon-gamma (IFN-gamma) release assay or tuberculin skin test, also known as PPD or Mantoux test.

Most studies included in the analysis were conducted in the past 10 years in countries with a high tuberculosis burden. Those countries included India, South Africa, China, Vietnam, Indonesia, Uganda, the Gambia, and Brazil.
 

Primary outcomes

The study’s main findings included the following:

• The overall effectiveness of BCG vaccination against all forms of tuberculosis was 18% (adjusted odds ratio, 0.82; 95% CI, 0.74-0.91).
• Stratified by age, BCG vaccination only significantly protected against all tuberculosis in children younger than 5 years (aOR, 0.63; 95% CI, 0.49-0.81).
• There was no protective effect among those whose previous tests for tuberculosis were negative unless they were younger than 5 years (aOR, 0.54; 95% CI, 0.32-0.90).
• Among contacts who had a positive tuberculin skin test or IFN-gamma release assay, BCG vaccination significantly protected against tuberculosis among all participants (aOR, 0.81; 95% CI, 0.69-0.96), participants younger than 5 years (aOR, 0.68; 95% CI, 0.47-0.97), and participants aged 5-9 years (aOR, 0.62; 95% CI, 0.38-0.99).
• BCG vaccination was protective against pulmonary tuberculosis (19% effectiveness), but this effect was only seen in children younger than 3 years (42% effectiveness) when stratified by age.
• Protection against all tuberculosis and pulmonary tuberculosis was greater among female participants than male participants.

“This is a definitive BCG protection study because it involves a significant number of individuals evaluated using this meta-analysis. Protection is clearly lost with age. From as early as age 5, no protective effect can be observed. Protection, including against pulmonary tuberculosis, can be observed up to 3 years of age,” stated study author Julio Croda, MD, PhD, chair of the Brazilian Society of Tropical Medicine.

Dr. Croda emphasized that the findings from their study indicate that BCG vaccine protects against pulmonary tuberculosis and that those results differ from results of some previous studies.

“Every physician believes the BCG vaccine protects against serious forms of tuberculosis up to age 5. That fact is not surprising at all,” Dr. Croda remarked. “However, the fact that it protects against pulmonary tuberculosis, especially in children younger than 3, was surprising. In medical practice, we did not believe in this protection.”

Currently, 1.2% of new tuberculosis cases in Brazil occur among those younger than 5. Nevertheless, these cases represent 40.1% of new diagnoses recorded among those younger than 15, highlighting the importance of protection for this age group. An increase in extrapulmonary tuberculosis cases was recently observed in patients younger than 5.

Isabella Ballalai, MD, PhD, is deputy chair of the Brazilian Society of Immunizations. Although she did not participate in this study, she commented on its findings. “All publications are welcome; they help us think,” she explained. She emphasized that the BCG vaccine is not optimal. “There are studies indicating 80% efficacy and others indicating 0%. So, what we can look at is decades of effectiveness in practice.”

Dr. Ballalai explained that the BCG vaccine could keep severe forms of tuberculosis, meningitis, and miliary tuberculosis at bay. She shared her experience of caring for several patients with tuberculous meningitis shortly after she had graduated. “Today, thanks to the BCG vaccine, we don’t see it anymore.” However, she pointed out that the vaccine›s efficacy and effectiveness against pulmonary tuberculosis are low and that pulmonary tuberculosis remains the most significant problem among adults.

Dr. Ballalai also emphasized a few shortcomings of the study. “One is the definition of ‘vaccinated’ and ‘unvaccinated,’ which was based on the presence or absence of a mark on the arm. Today, we know that the absence of a mark does not indicate that the child has not been vaccinated, nor that the vaccine has not been effective. Therefore, several vaccinated participants may have been included amongst the unvaccinated participants.”

The authors emphasized that the definition of “vaccinated” and “unvaccinated” was based on a scar and on vaccination records, and they recognized that participants who did not have a scar on their arm could have been misclassified. Regardless, it is still considered a sensitive indicator. “Few vaccinated children from various settings do not show a scar years after vaccine administration,” they stated in their article.
 

Adults unprotected

Dr. Ballalai also shared her concerns regarding the lack of protection for older individuals. “We know those older than 60 are at greater risk for complications of tuberculosis. Individuals in this age group naturally have a lower immunity, and they usually have comorbidities. From this study, I can only conclude what was already expected: that adults who received a BCG vaccine as infants are not clear of pulmonary tuberculosis.”

Dr. Croda agreed that it was already evident that the BCG vaccine administered at birth did not provide protection for adults. “In the past, even with 80%-90% vaccine coverage, there were numerous tuberculosis cases in adults in Brazil.”
 

Are boosters needed?

The authors concluded that immunoprotection needs to be boosted in older populations, as vaccination at birth is ineffective for adolescents and adults. They have also discussed whether children older than 10 years and adults could benefit from a booster shot.

Dr. Croda emphasized that there is no indication for this, because there are no data regarding protection with a booster dose during adulthood. However, he cited a study conducted in South Africa in which the BCG vaccine was compared with another vaccine, and another study, which is being conducted in India, is assessing whether a BCG booster offers protection against pulmonary tuberculosis. “There are few studies. Perhaps the revaccination of more vulnerable groups could be of interest, but additional studies are needed first.”

Dr. Croda intends to assess revaccination in those deprived of liberty, in which the incidence of tuberculosis is very high. From 2015 to 2021, many new cases were recorded in this population in Brazil. The number rose from 5,860 to 6,773 during that period.

“However, BCG revaccination carries a significant risk of patients presenting with serious adverse events,” Dr. Ballalai pointed out. He noted that several years ago, to extend protection, Brazil adopted a booster program for persons aged 10 years or older, but the program was discontinued owing to the numerous adverse events reported and the absence of evidence of benefit from increased protection against tuberculosis.

“The adult groups at greater risk for severe tuberculosis manifestations normally presented with an underlying disease, particularly in immunocompromised patient groups. The [administration of the] BCG [vaccine] is contraindicated for those who are immunocompromised. And, for the older population, we do not have data on [vaccine] safety,” she emphasized.
 

Nonspecific immune protection

One of the study’s secondary outcomes regarded mortality. Four studies in the meta-analysis followed up tuberculosis contacts for death. In these studies, which evaluated 20,000 participants, BCG vaccination was shown to be significantly protective against death for participants younger than 15 years.

However, the authors urged caution in interpreting these data. They emphasized that they were unable to identify specific mechanisms by which BCG vaccination might have reduced mortality, and there are possible study biases that could have led to an overestimation of mortality benefit. Moreover, given the observational nature of the included studies, vaccinated children might have had higher socioeconomic status and greater access to health care, and they may have been more likely to have received other vaccinations, compared with children who did not receive BCG vaccines.

Nevertheless, previous experimental and observational studies have found that BCG vaccination might provide nonspecific or off-target immune protection against an array of other pathogens.

“In small studies conducted in Africa, those younger than 5 were protected not only against tuberculosis but also against other respiratory diseases,” Dr. Croda affirmed. “However, these are small studies, and for now, there is no recommendation for using BCG vaccination to prevent other respiratory infections.”

A long-awaited, critical study on the impact of the BCG vaccine on COVID-19, in which Brazilian researchers participated, will be published in the New England Journal of Medicine.
 

New vaccines needed

The BCG vaccine is one of the oldest vaccines, but there are still several crucial unanswered questions about its use.

Previously published studies that examined the protective effect of BCG vaccination only considered low-burden settings and the historical literature before 1950. These studies need updating, but doing so has not been a simple task. To answer their questions, individual-level participant data for a prespecified list of variables, including the characteristics of the exposed participant (contact), the index case, and the environment, were requested from authors of all eligible studies.

Much of the data used in the published research were found through discussions with authors and experts in the field, as well as through data deposited in data storage repositories, conference abstracts, dissertations, and even direct requests to the authors. “The Pan-American Health Organization helped with this data collection and contacting some authors,” said Dr. Croda.

With the new data, the authors confirmed that infant BCG vaccination, although important to young children who are at high risk for tuberculosis, does not prevent adult-type cavitary tuberculosis and is therefore insufficient to impede the tuberculosis epidemic. “Novel vaccines are urgently needed,” they concluded.

“We need to develop novel, more effective vaccines, which, when administered during infancy, would ensure lifelong protection,” Dr. Croda added.

Dr. Croda and Dr. Ballalai reported no relevant financial relationships.

• Among contacts who had a positive tuberculin skin test or IFN-gamma release assay, BCG vaccination significantly protected against tuberculosis among all participants (aOR, 0.81; 95% CI, 0.69-0.96), participants younger than 5 years (aOR, 0.68; 95% CI, 0.47-0.97), and participants aged 5-9 years (aOR, 0.62; 95% CI, 0.38-0.99).
• BCG vaccination was protective against pulmonary tuberculosis (19% effectiveness), but this effect was only seen in children younger than 3 years (42% effectiveness) when stratified by age.
• Protection against all tuberculosis and pulmonary tuberculosis was greater among female participants than male participants.

“This is a definitive BCG protection study because it involves a significant number of individuals evaluated using this meta-analysis. Protection is clearly lost with age. From as early as age 5, no protective effect can be observed. Protection, including against pulmonary tuberculosis, can be observed up to 3 years of age,” stated study author Julio Croda, MD, PhD, chair of the Brazilian Society of Tropical Medicine.

Dr. Croda emphasized that the findings from their study indicate that BCG vaccine protects against pulmonary tuberculosis and that those results differ from results of some previous studies.

“Every physician believes the BCG vaccine protects against serious forms of tuberculosis up to age 5. That fact is not surprising at all,” Dr. Croda remarked. “However, the fact that it protects against pulmonary tuberculosis, especially in children younger than 3, was surprising. In medical practice, we did not believe in this protection.”

Currently, 1.2% of new tuberculosis cases in Brazil occur among those younger than 5. Nevertheless, these cases represent 40.1% of new diagnoses recorded among those younger than 15, highlighting the importance of protection for this age group. An increase in extrapulmonary tuberculosis cases was recently observed in patients younger than 5.

Isabella Ballalai, MD, PhD, is deputy chair of the Brazilian Society of Immunizations. Although she did not participate in this study, she commented on its findings. “All publications are welcome; they help us think,” she explained. She emphasized that the BCG vaccine is not optimal. “There are studies indicating 80% efficacy and others indicating 0%. So, what we can look at is decades of effectiveness in practice.”

Dr. Ballalai explained that the BCG vaccine could keep severe forms of tuberculosis, meningitis, and miliary tuberculosis at bay. She shared her experience of caring for several patients with tuberculous meningitis shortly after she had graduated. “Today, thanks to the BCG vaccine, we don’t see it anymore.” However, she pointed out that the vaccine›s efficacy and effectiveness against pulmonary tuberculosis are low and that pulmonary tuberculosis remains the most significant problem among adults.

Dr. Ballalai also emphasized a few shortcomings of the study. “One is the definition of ‘vaccinated’ and ‘unvaccinated,’ which was based on the presence or absence of a mark on the arm. Today, we know that the absence of a mark does not indicate that the child has not been vaccinated, nor that the vaccine has not been effective. Therefore, several vaccinated participants may have been included amongst the unvaccinated participants.”

The authors emphasized that the definition of “vaccinated” and “unvaccinated” was based on a scar and on vaccination records, and they recognized that participants who did not have a scar on their arm could have been misclassified. Regardless, it is still considered a sensitive indicator. “Few vaccinated children from various settings do not show a scar years after vaccine administration,” they stated in their article.
 

Adults unprotected

Dr. Ballalai also shared her concerns regarding the lack of protection for older individuals. “We know those older than 60 are at greater risk for complications of tuberculosis. Individuals in this age group naturally have a lower immunity, and they usually have comorbidities. From this study, I can only conclude what was already expected: that adults who received a BCG vaccine as infants are not clear of pulmonary tuberculosis.”

Dr. Croda agreed that it was already evident that the BCG vaccine administered at birth did not provide protection for adults. “In the past, even with 80%-90% vaccine coverage, there were numerous tuberculosis cases in adults in Brazil.”
 

Are boosters needed?

The authors concluded that immunoprotection needs to be boosted in older populations, as vaccination at birth is ineffective for adolescents and adults. They have also discussed whether children older than 10 years and adults could benefit from a booster shot.

Dr. Croda emphasized that there is no indication for this, because there are no data regarding protection with a booster dose during adulthood. However, he cited a study conducted in South Africa in which the BCG vaccine was compared with another vaccine, and another study, which is being conducted in India, is assessing whether a BCG booster offers protection against pulmonary tuberculosis. “There are few studies. Perhaps the revaccination of more vulnerable groups could be of interest, but additional studies are needed first.”

Dr. Croda intends to assess revaccination in those deprived of liberty, in which the incidence of tuberculosis is very high. From 2015 to 2021, many new cases were recorded in this population in Brazil. The number rose from 5,860 to 6,773 during that period.

“However, BCG revaccination carries a significant risk of patients presenting with serious adverse events,” Dr. Ballalai pointed out. He noted that several years ago, to extend protection, Brazil adopted a booster program for persons aged 10 years or older, but the program was discontinued owing to the numerous adverse events reported and the absence of evidence of benefit from increased protection against tuberculosis.

“The adult groups at greater risk for severe tuberculosis manifestations normally presented with an underlying disease, particularly in immunocompromised patient groups. The [administration of the] BCG [vaccine] is contraindicated for those who are immunocompromised. And, for the older population, we do not have data on [vaccine] safety,” she emphasized.
 

Nonspecific immune protection

One of the study’s secondary outcomes regarded mortality. Four studies in the meta-analysis followed up tuberculosis contacts for death. In these studies, which evaluated 20,000 participants, BCG vaccination was shown to be significantly protective against death for participants younger than 15 years.

However, the authors urged caution in interpreting these data. They emphasized that they were unable to identify specific mechanisms by which BCG vaccination might have reduced mortality, and there are possible study biases that could have led to an overestimation of mortality benefit. Moreover, given the observational nature of the included studies, vaccinated children might have had higher socioeconomic status and greater access to health care, and they may have been more likely to have received other vaccinations, compared with children who did not receive BCG vaccines.

Nevertheless, previous experimental and observational studies have found that BCG vaccination might provide nonspecific or off-target immune protection against an array of other pathogens.

“In small studies conducted in Africa, those younger than 5 were protected not only against tuberculosis but also against other respiratory diseases,” Dr. Croda affirmed. “However, these are small studies, and for now, there is no recommendation for using BCG vaccination to prevent other respiratory infections.”

A long-awaited, critical study on the impact of the BCG vaccine on COVID-19, in which Brazilian researchers participated, will be published in the New England Journal of Medicine.
 

New vaccines needed

The BCG vaccine is one of the oldest vaccines, but there are still several crucial unanswered questions about its use.

Previously published studies that examined the protective effect of BCG vaccination only considered low-burden settings and the historical literature before 1950. These studies need updating, but doing so has not been a simple task. To answer their questions, individual-level participant data for a prespecified list of variables, including the characteristics of the exposed participant (contact), the index case, and the environment, were requested from authors of all eligible studies.

Much of the data used in the published research were found through discussions with authors and experts in the field, as well as through data deposited in data storage repositories, conference abstracts, dissertations, and even direct requests to the authors. “The Pan-American Health Organization helped with this data collection and contacting some authors,” said Dr. Croda.

With the new data, the authors confirmed that infant BCG vaccination, although important to young children who are at high risk for tuberculosis, does not prevent adult-type cavitary tuberculosis and is therefore insufficient to impede the tuberculosis epidemic. “Novel vaccines are urgently needed,” they concluded.

“We need to develop novel, more effective vaccines, which, when administered during infancy, would ensure lifelong protection,” Dr. Croda added.

Dr. Croda and Dr. Ballalai reported no relevant financial relationships.

Visceral adipose tissue is significantly reduced with the green Mediterranean diet (MED), which consists of polyphenols and reduced red meat intake, according to a new analysis of the 18-month Dietary Intervention Randomized Controlled Trial Polyphenols Unprocessed (DIRECT-PLUS) trial.

The new results indicate that the green Mediterranean diet lowered visceral fat by twice as much as the standard Mediterranean diet (14% vs. 7%), reported Iris Shai, PhD, of Ben-Gurion University of the Negev in Be’er Sheva, Israel, and colleagues.

“This study may suggest an improved dietary protocol for treating visceral adiposity,” the authors wrote in their article, published recently in BMC Medicine.

“A healthy lifestyle is a strong basis for any weight-loss program. We learned from the results of our experiment that the quality of food is no less important than the number of calories consumed and the goal today is to understand the mechanisms of various nutrients, for example, positive ones such as the polyphenols, and negative ones such as empty carbohydrates and processed red meat, on the pace of fat cell differentiation and their aggregation in the viscera,” Dr. Shai said in a press release from Ben‐Gurion University.

“A 14% reduction in visceral fat is a dramatic achievement for making simple changes to your diet and lifestyle. Weight loss is an important goal only if it is accompanied by impressive results in reducing adipose tissue,” added coauthor Hila Zelicha, RD, PhD, also of Ben‐Gurion University of the Negev.

Previous randomized controlled trials have shown that dietary changes with a higher polyphenol content tend to produce better cardiometabolic outcomes and appear to mobilize particular ectopic fat depots, the researchers noted.

The main results of the DIRECT-PLUS trial were published in 2020 in Heart. Almost 300 participants with abdominal obesity/dyslipidemia were randomized to one of three diet groups (all accompanied by physical activity): standard healthy dietary guidelines (HDG), standard Mediterranean diet, and the so-called green Mediterranean diet. The mean age of participants was 51 years, and men comprised 88% of the study cohort.

Participants in both Mediterranean diet groups ate 28 grams/day of walnuts, which accounted for about 440 mg/day of polyphenols. Participants in the green Mediterranean group also ate 100 grams/day of frozen cubes of a Wolffia globosa (duckweed strain) plant green shake, and three to four cups/day of green tea, which contributed to consumption of 800 mg/day of polyphenols, and decreased red meat consumption.

Both the green and standard Mediterranean diet groups achieved similar weight loss (–6.2 kg and –5.4 kg) compared with the HDG group (–1.5 kg; P < .001). However, the green Mediterranean diet group had a greater reduction in waist circumference (–8.6 cm) than the standard Mediterranean diet group (–6.8 cm; P = .033) and HDG group (–4.3 cm; P < .001). Stratification by gender showed these differences were significant only among men.

Explaining the rationale for the study, the researchers noted that visceral adipose tissue accumulation is a key factor that differentiates metabolic healthy and unhealthy obese individuals, is closely related to the development of multiple cardiovascular risk factors, including hypertension, dyslipidemia, and type 2 diabetes, and is an independent marker of mortality.

Now, their latest data show the green Mediterranean diet group lost approximately twice as much visceral adipose tissue compared with the standard Mediterranean diet and HDG groups (−14.1%, −6.0%, and − 4.2%; P < .05 independent of weight loss, sex, waist circumference, or age).

Lower red meat consumption, greater dietary consumption of walnuts, Wolffia globosa, and green tea, increased urine urolithin A polyphenol, and elevated total plasma polyphenols were significantly associated with greater visceral adipose tissue loss (P < .05, multivariate models).

“A green Mediterranean diet enriched with polyphenols and decreased red meat consumption might serve as an improved version of the Mediterranean diet for targeted VAT reduction. Future studies are needed to explore the exact mechanisms of specific polyphenol-rich foods on visceral adiposity,” the study authors concluded.

The American Academy of Pediatrics is cautioning physicians and parents to be on the lookout for unnecessary diagnostic testing associated with several common pediatric conditions.

Children seen for these conditions in emergency settings and even in primary care offices could experience avoidable pain, exposure to harmful radiation, and other harms, according to the group.

“The emergency department has the ability to rapidly perform myriad diagnostic tests and receive results quickly,” said Paul Mullan, MD, MPH, chair of the AAP’s Section of Emergency Medicine’s Choosing Wisely task force. “However, this comes with the danger of diagnostic overtesting.”

The five recommendations are as follows:

• Radiographs should not be obtained for children with bronchiolitis, croup, asthma, or first-time wheezing.
• Laboratory tests for screening should not be undertaken in the medical clearance process of children who require inpatient psychiatric admission unless clinically indicated.
• Laboratory testing or a CT scan of the head should not be ordered for a child with an unprovoked, generalized seizure or a simple febrile seizure whose mental status has returned to baseline.
• Abdominal radiographs should not be obtained for suspected constipation.
• Comprehensive viral panel testing should not be undertaken for children who are suspected of having respiratory viral illnesses.

The AAP task force partnered with Choosing Wisely Canada to create the recommendations. The list is the first of its kind to be published jointly by two countries, according to the release.

“We hope this Choosing Wisely list will encourage clinicians to rely on their clinical skills and avoid unnecessary tests,” said Dr. Mullan, who is also a physician at Children’s Hospital of the King’s Daughters and professor of pediatrics at Eastern Virginia Medical School, Norfolk.

The offspring of mothers who sustain unintentional injuries during pregnancy appear to have a modest 33% increased risk of developing cerebral palsy (CP) – higher when injuries are more severe, multiple, or lead to delivery soon afterward, a Canadian birth cohort study found.

Such children may benefit from long-term monitoring for neurodevelpmental issues, wrote a group led by Asma Ahmed, MD, PhD, MPH, a pediatric epidemiologist at the Hospital for Sick Children Research Institute in Toronto in JAMA Pediatrics.

“We need to provide better support for babies whose mothers have been injured in pregnancy, especially after severe injuries,” Dr. Ahmed said in a press release. “As well, these findings suggest the need for early monitoring of babies’ development, regular check-ups, and longer-term neurodevelopmental assessments.” Future studies should directly measure injury severity and its possible link to CP.

Current guidelines, however, focus on monitoring fetal condition immediately after injury with little attention to its long-term effects.

In their findings from the population-based linkage study of 2,110,177 children born in Ontario’s public health system during 2002-2017 and followed to 2018 with a median follow-up of 8 years:

• A total of 81,281 fetuses were exposed in utero to unintentional maternal injury.
• Overall, 0.3% children were diagnosed with CP, and the mean CP incidence rates were 4.36 per 10,000 child-years for the exposed versus 2.93 for the unexposed.
• In those exposed, the hazard ratio was 1.33 (95% confidence interval, 1.18-1.50) after adjusting for maternal sociodemographic and clinical characteristics.
• Injuries resulting in hospitalization or delivery within 1 week were linked to higher adjusted hazard ratios of 2.18 (95% CI, 1.29-3.68) and 3.40 (95% CI, 1.93-6.00), respectively.
• Injuries most frequently resulted from transportation mishaps, falls, and being struck by a person or object. They were most commonly associated with age younger than 20 years, substance use disorder, residence in rural and under-resourced areas, and lower socioeconomic status.

The authors noted that complications after maternal injuries – which affect 6%-8% of pregnant women – include uterine rupture, preterm delivery, and placental abruption and are linked to fetal complications such as asphyxia. The association with an offspring’s neurodevelopment has been rarely investigated. One U.K. population study, however, suggested a link between vehicular crashes and higher CP risk in preterm infants.

A related editorial on the study noted that while CP affects about two to four children per 1,000 live births each year in high-income countries, the etiological causes of most cases remain unknown. “This large population-based cohort study ... should inspire more research into preventing and mitigating factors for maternal injuries and offspring CP development,” wrote Zeyan Liew, PhD, MPH, and Haoran Zhuo, MPH, of Yale University School of Public Health in New Haven, Conn.

This study was supported by Santé-Québec and ICES, a research institute funded by the Ontario Ministry of Health and the Ministry of Long-Term Care.

The authors noted that complications after maternal injuries – which affect 6%-8% of pregnant women – include uterine rupture, preterm delivery, and placental abruption and are linked to fetal complications such as asphyxia. The association with an offspring’s neurodevelopment has been rarely investigated. One U.K. population study, however, suggested a link between vehicular crashes and higher CP risk in preterm infants.

A related editorial on the study noted that while CP affects about two to four children per 1,000 live births each year in high-income countries, the etiological causes of most cases remain unknown. “This large population-based cohort study ... should inspire more research into preventing and mitigating factors for maternal injuries and offspring CP development,” wrote Zeyan Liew, PhD, MPH, and Haoran Zhuo, MPH, of Yale University School of Public Health in New Haven, Conn.

This study was supported by Santé-Québec and ICES, a research institute funded by the Ontario Ministry of Health and the Ministry of Long-Term Care.

(Reuters) – Eli Lilly’s COVID-19 drug bebtelovimab is not currently authorized for emergency use in the United States, the Food and Drug Administration said, citing it is not expected to neutralize the dominant BQ.1 and BQ.1.1 subvariants of Omicron.

The announcement on Nov. 30 takes away authorization from the last COVID-19 monoclonal antibody treatment, leaving Pfizer’s antiviral drug Paxlovid, Merck’s Lagevrio, and Gilead Sciences’ Veklury as treatments for the disease, besides convalescent plasma for some patients.

AstraZeneca’s monoclonal antibody Evusheld is also authorized for protection against COVID-19 infection in some people.

Eli Lilly and its authorized distributors have paused commercial distribution of the monoclonal antibody until further notice from the agency, while the U.S. government has also paused fulfillment of any pending requests under its scheme to help uninsured and underinsured Americans access the drug.

The drug, which was discovered by Abcellera and commercialized by Eli Lilly, received an authorization from the FDA in February.

BQ.1 and BQ.1.1 have become the dominant strains in the United States after a steady increase in prevalence over the last 2 months, surpassing Omicron’s BA.5 subvariant, which had driven cases earlier in the year.

The subvariants accounted for around 57% of the cases nationally, as per government data last week.

Doctors suspect the worst respiratory syncytial virus (RSV) season in years just ended, and the story of a child who had a serious respiratory infection provides a glimpse of what health care providers saw in the fall of 2022.

RSV cases peaked in mid-November, according to the latest Centers for Disease Control and Prevention data, with RSV-associated hospitalizations in the United States among patients 0-4 years having maxed out five times higher than they were at the same time in 2021. These surges strained providers and left parents scrambling for care. Fortunately, pediatric hospitalizations appear to be subsiding.

In interviews, the parents of the child who had a severe case of RSV reflected on their son’s bout with the illness, and doctors described challenges to dealing with the surge in RSV cases this season. The physicians also offered advice on how recognize and respond to future cases of the virus.
 

Sebastian Witt’s story

“I didn’t even know what RSV was,” said Malte Witt, whose son, Sebastian, 2, was recently hospitalized for RSV in Denver.

Mr. Witt and his wife, Emily Witt, both 32, thought they were dealing with a typical cold until Sebastian’s condition dramatically deteriorated about 36 hours after symptom onset.

“He basically just slumped over and collapsed, coughing uncontrollably,” Mr. Witt said in an interview. “He couldn’t catch his breath.”

The Witts rushed Sebastian to the ED at Children’s Hospital Colorado, expecting to see a doctor immediately. Instead, they spent the night in an overcrowded waiting room alongside many other families in the same situation.

“There was no room for anyone to sit anywhere,” Mr. Witt said. “There were people sitting on the floor. I counted maybe six children hooked up to oxygen when we walked in.”

After waiting approximately 45 minutes, a nurse checked Sebastian’s oxygen saturation. The readings were 79%-83%. This range is significantly below thresholds for supplemental oxygen described by most pediatric guidelines, which range from 90 to 94%.

The nurse connected Sebastian to bottled oxygen in the waiting room, and a recheck 4 hours later showed that his oxygen saturation had improved.

But the improvement didn’t last.

“At roughly hour 10 in the waiting room – it was 4 in the morning – you could tell that Seb was exhausted, really not acting like himself,” Mr. Witt said. “We thought maybe it’s just late at night, he hasn’t really slept. But then Emily noticed that his oxygen tank had run out.”

Mr. Witt told a nurse, and after another check revealed low oxygen saturation, Sebastian was finally admitted.
 

Early RSV surge strains pediatric providers

With RSV-associated hospitalizations peaking at 48 per 100,000 children, Colorado has been among the states hardest hit by the virus. New Mexico – where hospitalizations peaked at 56.4 per 100,000 children – comes in second. Even in states like California, where hospitalization rates have been almost 10-fold lower than New Mexico, pediatric providers have been stretched to their limits.

“Many hospitals are really being overwhelmed with admissions for RSV, both routine RSV – relatively mild hospitalizations with bronchiolitis – as well as kids in the ICU with more severe cases,” said Dean Blumberg, MD, chief of the division of pediatric infectious diseases at UC Davis Health, Sacramento, said in an interview.

Dr. Blumberg believes the severity of the 2022-2023 RSV season is likely COVID related.

“All community-associated respiratory viral infections are out of whack because of the pandemic, and all the masking and social distancing that was occurring,” he said.

This may also explain why older kids are coming down with more severe cases of RSV.

“Some children are getting RSV for the first time as older children,” Dr. Blumberg said, noting that, historically, most children were infected in the first 2 years of life. “There are reports of children 3 or 4 years of age being admitted with their first episode of RSV because of the [COVID] pandemic.”

This year’s RSV season is also notable for arriving early, potentially catching the community off guard, according to Jennifer D. Kusma, MD, a primary care pediatrician at Ann & Robert H. Lurie Children’s Hospital of Chicago.

“People who should have been protected often weren’t protected yet,” Dr. Kusma said in an interview.
 

Treatments new, old, and unproven

On Nov. 17, in the midst of the RSV surge, the American Academy of Pediatrics issued updated guidance for palivizumab, an RSV-targeting monoclonal antibody labeled for children at risk of severe RSV, including those with pre-existing lung or heart conditions, and infants with a history of premature birth (less than or equal to 35 weeks’ gestational age).

“If RSV disease activity persists at high levels in a given region through the fall and winter, the AAP supports providing more than five consecutive doses of palivizumab to eligible children,” the update stated.

Insurance companies appear to be responding in kind, covering additional doses for children in need.

“[Payers] have agreed that, if [palivizumab] needs to be given for an additional month or 2 or 3, then they’re making a commitment that they’ll reimburse hospitals for providing that,” Dr. Blumberg said.

For ineligible patients, such as Sebastian, who was born prematurely at 36 weeks – 1 week shy of the label requirement – treatment relies upon supportive care with oxygen and IV fluids.

At home, parents are left with simpler options.

Dr. Blumberg and Dr. Kusma recommended keeping children hydrated, maintaining humidified air, and using saline nose drops with bulb suction to clear mucus.

In the Witts’ experience, that last step may be easier said than done.

“Every time a nurse would walk into the room, Sebastian would yell: ‘Go away, doctor! I don’t want snot sucker!’” Mr. Witt said.

“If you over snot-suck, that’s really uncomfortable for the kid, and really hard for you,” Ms. Witt said. “And it doesn’t make much of a difference. It’s just very hard to find a middle ground, where you’re helping and keeping them comfortable.”

Some parents are turning to novel strategies, such as nebulized hypertonic saline, currently marketed on Amazon for children with RSV.

Although the AAP offers a weak recommendation for nebulized hypertonic saline in children hospitalized more than 72 hours, they advise against it in the emergency setting, citing inconsistent findings in clinical trials.

To any parents tempted by thousands of positive Amazon reviews, Dr. Blumberg said, “I wouldn’t waste my money on that.”

Dr. Kusma agreed.

“[Nebulized hypertonic saline] can be irritating,” she said. “It’s saltwater, essentially. If a parent is in the position where they’re worried about their child’s breathing to the point that they think they need to use it, I would err on the side of calling your pediatrician and being seen.”
 

Going in, coming home

Dr. Kusma said parents should seek medical attention if a child is breathing faster and working harder to get air. Increased work of breathing is characterized by pulling of the skin at the notch where the throat meets the chest bone (tracheal tugging), and flattening of the belly that makes the ribcage more prominent.

Mr. Witt saw these signs in Sebastian. He knew they were significant, because a friend who is a nurse had previously shown him some examples of children who exhibited these symptoms online.

“That’s how I knew that things were actually really dangerous,” Mr. Witt said. “Had she not shown me those videos a month and a half before this happened, I don’t know that we would have hit the alarm bell as quickly as we did.”

After spending their second night and the following day in a cramped preoperative room converted to manage overflow from the emergency department, Sebastian’s condition improved, and he was discharged. The Witts are relieved to be home, but frustrations from their ordeal remain, especially considering the estimated $5,000 in out-of-pocket costs they expect to pay.

“How is this our health care system?” Ms. Witt asked. “This is unbelievable.”
 

An optimistic outlook

RSV seasons typically demonstrate a clear peak, followed by a decline through the rest of the season, suggesting better times lie ahead; however, this season has been anything but typical.

“I’m hopeful that it will just go away and stay away,” Dr. Kusma said, citing this trend. “But I can’t know for sure.”

To anxious parents, Dr. Blumberg offered an optimistic view of RSV seasons to come.

“There’s hope,” he said. “There are vaccines that are being developed that are very close to FDA approval. So, it’s possible that this time next year, we might have widespread RSV vaccination available for children so that we don’t have to go through this nightmare again.”

Dr. Blumberg and Dr. Kusma disclosed no relevant conflicts of interest.

The debate about a possible link between food allergy (FA) and pediatric gastroesophageal reflux disease (GERD) continues, and more, better-designed research is needed, a position paper by the European Academy of Allergy and Clinical Immunology reports.

The report offers consensus-based recommendations and a graphical decision pathway to guide providers through assessing and treating food allergy–related GERD. And the authors call for further, better-designed related research.

Food allergy and GERD are common in babies under 1 year of age and can lead to bothersome GERD, the authors write.

“An extensive literature search has found that whilst food proteins, in particular cow milk protein, can be a contributing factor to FA-associated” GERD, distinguishing between FA and non–FA-associated GERD is difficult, lead author Rosan Meyer, RD, PhD, senior lecturer at Imperial College London, and colleagues from the Academy task force on non-IgE mediated allergy, write in Pediatric Allergy and Immunology.
 

Consensus despite limited data

Dr. Meyer and colleagues developed clinical questions that addressed various aspects of the relationship between food allergy and GERD – pathophysiology, symptoms, diagnosis, dietary and medical management, prevalence, and impact on quality of life.

To address these issues, they systematically searched the literature for randomized controlled, observational, case-control, and retrospective studies of infants and children diagnosed with non-IgE gastrointestinal food allergies and GERD, published in English until February 2021.

Because of limited data in many of these areas, they used a modified Delphi method to reach consensus and provide practical advice on food allergy–associated GERD management.

The task force concludes:

• Food proteins, especially cow’s milk protein, can contribute to food allergy–associated GERD. The confirmation of food allergy is based on the elimination diet, always followed by reintroducing the offending allergen, and the diagnosis and treatment pathway should consider effects on quality of life.
• Breastfeeding should be supported in food allergy–associated GERD, and dietary advice should consider the potential nutritional impact on the breastfeeding mother. When breast milk is not available or is insufficient, formula and dietary advice to counteract the child’s nutrient deficiencies should be considered.
• Although some clarity exists about when GERD medications may be considered, they are often used inappropriately and may harm patients, especially infants.

Rigorous research needed

“Clinicians can use this algorithm to help them identify patients who may be affected by food allergy–related GERD,” Jonathan Tam, MD, medical director of the Gores Family Allergy Center at Children’s Hospital Los Angeles, told this news organization by email.

“Clinicians who suspect their patients may have food allergy–related GERD now have clearer guidance on how to systemically evaluate their patients,” added Dr. Tam, who was not involved in developing the report.

“Many allergists fear that patients may be labeled with a food allergy unnecessarily. Because no biomarkers or tests for food allergy–related GERD are available, elimination diets are a crucial part of the evaluation,” he said.

Dr. Tam added that the authors point out two key parts of a trial elimination: First, the trial should last at least 2 weeks, but full resolution may not occur until 6 weeks. Second, targeted elimination must be followed by reintroduction to confirm that the food was causing the symptoms, not that time itself may have been responsible for the clinical change.

“The authors’ note on allergy testing is important,” he said. “Allergy testing is not necessary when a clinician is concerned about food allergy–related GERD unless there are other associated atopic comorbidities, like eczema or IgE-mediated immediate food allergies.”

Jonathan M. Spergel, MD, PhD, chief of the allergy section at Children’s Hospital of Philadelphia, said in an email that families often ask whether food allergy is causing their child’s reflux.

“Both conditions are common and, in most cases, may not be related. As the report highlights, the risk of food allergy is increased if the patient has other atopic disease (atopic dermatitis), and standard allergy testing (skin testing, specific IgE) and IgG4 testing are not recommended,” he explained. “Food allergy in a patient with reflux can be considered if standard therapy is failing.”
 

Expert opinion on diagnosis and management

Dr. Spergel, also not involved in the report, joined the authors in advocating further, stronger studies. “While the expert opinion is a major strength,” he said, “with most available studies being neither randomized nor placebo-controlled, the true prevalence of food allergy reflux is unknown.”

Jay M. Portnoy, MD, specialist in pediatric allergy and immunology and medical director of telemedicine at Children’s Mercy Kansas City, said: “While most physicians believe that food allergy contributes to GERD, the evidence for the relationship is minimal. Reflux often occurs regardless of what food is eaten,” said Dr. Portnoy, who was not associated with the research.

Before removing a food from the diet, it’s important to determine whether that food is causing the problem, he urged.

“Blaming a food is easy. Food allergy is often suspected to cause symptoms it does not cause,” he said. “This unfounded blame can lead to unnecessary avoidance, reduce a family’s quality of life, and cause malnutrition.

“How a child is evaluated and treated depends as much on which physician they see as on whether the food is the culprit,” Dr. Portnoy said. “This report is an attempt to clarify the issues and to standardize an approach to the condition, so each provider evaluates and manages the condition in a consistent and evidence-based manner.

“It is important to see how well this report is incorporated into practice and whether following its guidance actually improves patient care,” Dr. Portnoy noted.

The debate about a possible link between food allergy (FA) and pediatric gastroesophageal reflux disease (GERD) continues, and more, better-designed research is needed, a position paper by the European Academy of Allergy and Clinical Immunology reports.

The report offers consensus-based recommendations and a graphical decision pathway to guide providers through assessing and treating food allergy–related GERD. And the authors call for further, better-designed related research.

Food allergy and GERD are common in babies under 1 year of age and can lead to bothersome GERD, the authors write.

“An extensive literature search has found that whilst food proteins, in particular cow milk protein, can be a contributing factor to FA-associated” GERD, distinguishing between FA and non–FA-associated GERD is difficult, lead author Rosan Meyer, RD, PhD, senior lecturer at Imperial College London, and colleagues from the Academy task force on non-IgE mediated allergy, write in Pediatric Allergy and Immunology.
 

Consensus despite limited data

Dr. Meyer and colleagues developed clinical questions that addressed various aspects of the relationship between food allergy and GERD – pathophysiology, symptoms, diagnosis, dietary and medical management, prevalence, and impact on quality of life.

To address these issues, they systematically searched the literature for randomized controlled, observational, case-control, and retrospective studies of infants and children diagnosed with non-IgE gastrointestinal food allergies and GERD, published in English until February 2021.

Because of limited data in many of these areas, they used a modified Delphi method to reach consensus and provide practical advice on food allergy–associated GERD management.

The task force concludes:

• Food proteins, especially cow’s milk protein, can contribute to food allergy–associated GERD. The confirmation of food allergy is based on the elimination diet, always followed by reintroducing the offending allergen, and the diagnosis and treatment pathway should consider effects on quality of life.
• Breastfeeding should be supported in food allergy–associated GERD, and dietary advice should consider the potential nutritional impact on the breastfeeding mother. When breast milk is not available or is insufficient, formula and dietary advice to counteract the child’s nutrient deficiencies should be considered.
• Although some clarity exists about when GERD medications may be considered, they are often used inappropriately and may harm patients, especially infants.

Rigorous research needed

“Clinicians can use this algorithm to help them identify patients who may be affected by food allergy–related GERD,” Jonathan Tam, MD, medical director of the Gores Family Allergy Center at Children’s Hospital Los Angeles, told this news organization by email.

“Clinicians who suspect their patients may have food allergy–related GERD now have clearer guidance on how to systemically evaluate their patients,” added Dr. Tam, who was not involved in developing the report.

“Many allergists fear that patients may be labeled with a food allergy unnecessarily. Because no biomarkers or tests for food allergy–related GERD are available, elimination diets are a crucial part of the evaluation,” he said.
