Atopic Dermatitis: Upadacitinib Effectiveness Maintained Through 76 weeks Among Adolescents
TOPLINE:
across three phase 3 trials.
METHODOLOGY:
- Researchers conducted three double-blind, placebo-controlled phase 3 randomized clinical trials (Measure Up 1, Measure Up 2, and AD Up) involving 542 adolescents aged 12-17 years with moderate to severe AD.
- Participants were randomized to receive the oral Janus kinase inhibitor upadacitinib (15 mg or 30 mg once daily) or placebo, with or without topical corticosteroids, for 16 weeks, followed by rerandomization of patients in the placebo group to upadacitinib for up to 76 weeks.
- Study endpoints were at least a 75%, 90%, or 100% reduction in the Eczema Area and Severity Index (EASI-75, EASI-90, and EASI-100, respectively), Validated Investigator Global Assessment for AD (vIGA-AD) score of 0 or 1, and a ≥ 4-point improvement in the Worst Pruritus Numerical Rating Scale (WP-NRS).
- Adverse events were monitored, including serious infections, herpes zoster, and creatine kinase elevation.
TAKEAWAY:
- Among those who continued treatment on upadacitinib, 15 mg and 30 mg, EASI-75 response rates were maintained or improved through week 76 in all three studies. Patients who switched from placebo to upadacitinib also experienced improvements in EASI-75 through week 76.
- The proportion of patients who achieved EASI-90 and EASI-100 responses increased, and in general, were maintained from week 16 through week 76 in all three studies; the proportion was numerically higher among patients on 30 mg for all three studies.
- The proportion of adolescents achieving vIGA-AD score of 0 or 1 and WP-NRS improvement of ≥ 4 points was sustained or improved through 76 weeks.
- Serious infections were reported in five patients or fewer in each treatment group for all three studies. All opportunistic infections were eczema herpeticum; most cases were not serious, or were mild or moderate, and in general, did not require stopping treatment.
IN PRACTICE:
“These results through 76 weeks demonstrated that upadacitinib, with a favorable benefit-risk profile, was an effective long-term treatment option for adolescents with moderate to severe AD,” the authors wrote.
SOURCE:
The study was led by Amy S. Paller, MD, professor and chair of dermatology, Northwestern University, Chicago, and was published online on October 23 in JAMA Dermatology.
LIMITATIONS:
The study limitations included a small sample size, and the findings did not extend to patients under 12 years or those weighing < 40 kg.
DISCLOSURES:
This study was supported by AbbVie. Paller received grants and personal fees from pharmaceutical companies including AbbVie during the conduct of the study. Several authors reported financial ties with various sources, including AbbVie.

A Dermatologist’s Tips for Supporting LGBTQ Youth
HUNTINGTON BEACH, CALIFORNIA —
“Sometimes in dermatology we might say, ‘This gender care stuff, that’s really for pediatricians and primary care doctors,’ ” Boos, a pediatric dermatologist at Seattle Children’s Hospital, Seattle, said at the annual meeting of the Pacific Dermatologic Association. However, he added, “gender-affirming care happens not only with medications but with communication, curiosity, and respect.” For instance, an LGBTQ patient who is being treated with isotretinoin for acne is seen once a month by a dermatologist, which is probably more frequent than seeing their primary care physician, he said. “Every time you see that child, you can make them feel seen. You can respect them. You can let them know that you care about them. Hopefully then they understand what it feels like to get good care from a provider and then will not settle for poor care from someone else.”
According to Gallup polling, the proportion of people in the United States who identify as non-cisgender or nonheterosexual increased from 3.5% in 2012 to 7% in 2021. “The estimation is that 2.5%-3.5% of all teenagers identify as gay or bisexual, and another 1% identify as transgender, though some studies estimate the percentage of gender diverse youth to be as high as 9.2%,” said Boos.
He discussed several barriers to dermatologic care for LGBTQ youth, including availability. “There are only about 400 practicing pediatric dermatologists in the US, so there’s not a lot of pediatric dermatology care to go around for any child,” Boos said. “My plea to general dermatologists who see adolescents and teenagers: You can care for LGBTQ adolescents; they need your help.”
Accessibility is also an issue. For example, his clinic is in a wealthy and somewhat isolated area of Seattle, “which makes it hard for some patients to access our services because they may have to drive from far away or take multiple modes of public transportation to see us,” explained Boos, who came out as gay about 10 years ago after beginning his practice in Seattle. “Time matters, too. Children are in school. They don’t necessarily want to take time off to go to the doctor’s office. We want to make sure we have services at different times of day, including evenings or weekends if possible.”
Another potential barrier to care for this patient population is acceptability. “I can say that I welcome any patient to my practice, but if I’m not humble and informed about their concerns, especially queer or trans kids, if they feel that I’m not respecting them, that’s going to be a huge problem,” Boos said. “They won’t view that care as acceptable, and they’re not going to come back if they feel like I’m not looking out for their best interests.”
In a large cross-sectional study of patients with chronic inflammatory skin diseases published in 2023, sexual and gender minority (SGM) individuals were significantly more likely than non-SGM individuals to delay specialist care including dermatologic care (adjusted odds ratio [AOR], 1.23), mental health care (AOR, 1.62), and filing a prescription (AOR, 1.30) because of cost. The barriers for SGM patients were transportation issues, not having a healthcare practitioner (HCP) from the same racial or ethnic background, “and they were more likely to report not always being treated with respect by HCPs,” said Boos, who was not involved with the study. “SGM patients of minoritized racial identities such as Black, Hispanic, and Latino were also more likely to experience barriers to care.”
Boos offered several tips for improving the dermatologic care of LGBTQ youth:
Use inclusive language and follow your patient’s lead. “There are many ways that people identify, both with respect to their sexual orientation and their gender identity,” he said. “We often think that a person is either gay or straight, or cisgender or transgender. There are many folks who reject these binaries and may view their gender identity or sexual orientation outside of these descriptors. You can be bisexual. You can be asexual.” He also emphasized that sexual orientation is different from sexual behavior.
Be deliberate about your phrasing. Boos said he strives to make new patients feel comfortable by asking them such questions as what pronouns they use, how he should address them, and whether they have a partner or are in a relationship. “Then, in general, just follow your patient’s lead,” Boos said. “If they’re referring to their partner in a certain way or to themselves with certain pronouns, go along with it. When in doubt, just ask. And if you make a mistake like using the wrong pronouns or name of a patient, the best thing to do is immediately apologize and try your best not to repeat that error.”
When asking about sexual practices, don’t make assumptions. Boos recommends a 2019 article on dermatologic care of LGBT persons, published in the Journal of the American Academy of Dermatology, which includes specific examples of how to elicit a sexual history from adults and teens. One of the recommendations is “to be very direct, say, ‘This may feel uncomfortable, but I have to ask you these direct questions about what you’re doing sexually because I need to understand if you’re at risk for things like sexually transmitted infections,’ ” Boos said. “It’s also important to use terminology that our patients know. If I ask someone if they’ve had sex before, they usually understand that as penile-vaginal intercourse, but it’s also important to understand if they have oral or anal sex. But if you ask, ‘Have you had insertive anal sex?’ they may not know what that means as opposed to receptive anal sex. Instead, you might ask, ‘Are you a top or a bottom?’ which are more commonly used and understood terms in the queer community. It may feel really uncomfortable to use that kind of language, but we want to make sure patients understand what we’re asking them so we can take the best possible care of them.”
Pay attention to the details. One way to demonstrate inclusivity in your practice includes collecting pronoun and sexual orientation information for the electronic medical record so your entire staff can use proper pronouns for the patient. “Also, acknowledge that for queer folks, family can mean more than just biological family,” Boos added. “I do not buy into the stereotype that all queer kids are ostracized from their families and not loved by their families, but it is true that they are at risk for those experiences. So, sometimes a member of the patient’s ‘chosen family’ accompanies them on their visit.”
Privacy is also key. “You never know who else is in the room when you’re on a telehealth call, so you need to address that before you ask about personal things,” Boos said. “One sticking point that can also come up is that parents often fill out their child’s patient demographic form, which may not tell the real story. I typically start to have confidential time without parents and may take a sexual history as early as 12 or 13 years of age if it’s a patient that I’m seeing for an extended period or if I’m worried about a skin finding that might suggest an STI.”
He highlighted the unique opportunity dermatologists have to transform the healthcare landscape for LGBTQ children and adolescents. “It’s about extending yourself to nurture the growth of another person,” Boos said. “This can feel challenging, but you want to see each person for who they are and help get them to where they want to go. That’s what we went into medicine for, right? We want to care about people.”
Boos had no relevant financial disclosures.

Therapeutic Drug Monitoring in Rheumatology: A Promising Outlook But Many Barriers to Overcome
Therapeutic drug monitoring (TDM) — the practice of using laboratory testing to measure blood levels of drugs — has garnered growing interest among rheumatologists in managing patients on disease-modifying antirheumatic drugs (DMARDs), but that hasn’t exactly translated to widespread practice.
While TDM has made some inroads with patients taking monoclonal antibodies, specifically infliximab, its uptake has encountered a number of headwinds, not the least of which is a lack of evidence and clinical guidelines, uneven access and standards of assays, and even an uncertainty about how to interpret laboratory results.
“In some fields, such as neurology, TDM is accepted for antiepileptics,” Michelle Petri, MD, MPH, director of the Johns Hopkins Lupus Center, Baltimore, told Medscape Medical News. “In rheumatology, though, TDM is underutilized and not adequately championed by the American College of Rheumatology.”
She noted that TDM is most acutely needed for management of systemic lupus erythematosus, where nonadherence is a major problem. “Whole blood hydroxychloroquine monitoring has proven beneficial for identifying nonadherence, but also to pinpoint patients who are on too much, a risk factor for retinopathy,” Petri said.
“The state of therapeutic drug monitoring in general has been interesting when you think about its use in autoimmune disease because it’s very much used in gastroenterology and it’s been much less used in rheumatology,” Zachary Wallace, MD, codirector of the Rheumatology & Allergy Clinical Epidemiology Research Center at Massachusetts General Hospital in Boston, told Medscape Medical News. “Some of that may have to do with the interpretation of the availability of evidence, but I think it’s something clinicians will come across more and more often in their practice and wondering what its role might be,” he added.
The movement to precision medicine also portends to grow interest in TDM in rheumatology, said Stephen Balevic, MD, PhD, a rheumatologist and pharmacologist at Duke University and director of pharmacometrics at the Duke Clinical Research Institute, Durham, North Carolina.
“It’s a very exciting time for rheumatologists to begin thinking outside box on what it means to study precision medicine, and I think pharmacology is one of the most overlooked aspects of precision medicine in our community,” he told Medscape Medical News.
That may be because older DMARDs, namely hydroxychloroquine and methotrexate, came to market when regulatory requirements were different than they are today, Balevic said. “Many of the older conventional DMARDs were discovered incidentally and never really had the traditional pharmacokinetic-pharmacodynamic trials to determine optimal dosing, or perhaps that was extrapolated from other populations,” he said.
So, the “one-size-fits-all” approach does not work for prescribing older or even some of the newer DMARDs for rheumatologic disorders, Balevic said.
Reactive vs Proactive TDM
Among the few trials that examined TDM in rheumatology patients are the NOR-DRUM A and B trials in Norway. Marthe Brun, MD, PhD, a rheumatologist at the Center for Treatment of Rheumatic and Musculoskeletal Diseases at Diakonhjemmet Hospital in Oslo, Norway, and a coauthor of the NOR-DRUM trials, told Medscape Medical News that the trials found an overall benefit to TDM during infliximab maintenance therapy. The trials included not only patients with inflammatory arthritis (rheumatoid arthritis, psoriatic arthritis, and spondyloarthritis) but also patients with inflammatory bowel disease and psoriasis, Brun said.
Brun explained that two types of TDM exist: Reactive and proactive. “Reactive TDM is when you use it to find the reason for a patient having a flare or disease worsening,” she told Medscape Medical News. “Proactive TDM would be regular testing to keep a patient within a therapeutic range to avoid flare because of low drug concentrations.”
Gastroenterologists are more inclined than rheumatologists and dermatologists to use reactive TDM, she said. “There have been no recommendations regarding proactive TDM because of the lack of data.”
In Europe, Wallace noted that European Alliance of Associations for Rheumatology (EULAR) recommendations consider the use of TDM in specific clinical scenarios, such as when treatment fails or to evaluate immunogenicity of a reaction, but they are limited. The American College of Rheumatology (ACR) does not have any recommendations for the use of TDM.
Based on the NOR-DRUM trials, rheumatologists in Norway have published their own guidelines for TDM for infliximab in rheumatologic disease, but they are in Norwegian and have not yet been taken up by EULAR, Brun noted. Publication of those recommendations in English is pending, she said.
“But for other subcutaneously administered TNF inhibitors, there’s a lack of data,” Brun added.
The State of the Evidence
NOR-DRUM A did not support the use of proactive TDM in the 30-week induction period as a way to improve disease remission in patients with chronic immune-mediated inflammatory disease. NOR-DRUM B, which evaluated TDM over a year, found the approach was more likely to lead to sustained disease control for that period.
Brun’s group recently published an analysis of the trials. “We did not find an overall effect during the initial phase of the treatment, the first 30 weeks,” she told Medscape Medical News.
“Then we looked at subgroups, and we found that the patients that developed antidrug antibodies [ADAs] had an effect, and ADA are associated with poorer outcomes as well as infusion reactions for patients treated with infliximab.
“So, it’s probably a benefit to be able to detect these ADA early before the patient experiences a disease flare or infusion reaction,” Brun added. “It facilitates for the clinician to take action to, for example, increase the dosing or switch therapy.”
However, the quality of the data supporting TDM in rheumatology is limited, Balevic said. “There’s very good observational data, but we have very few clinical trials that actually leverage TDM,” he said.
NOR-DRUM is the exception, he said. “Ideally, we need more of these dose-optimization trials to help guide clinical practice,” he said. But it stands alone.
Wallace noted several take-home messages from the NOR-DRUM trials, namely that using TDM to prevent ADA may be more effective during the maintenance phase of treatment than the induction phase. However, he said, the evidence is still emerging.
“It’s reasonable to say that we’re at an early stage of the evidence,” he said. “If you look at the large trials that have been done in rheumatology, they’ve combined patients with many different types of conditions, and a lot of our recommendations in rheumatology are disease-specific — in rheumatoid arthritis, in vasculitis. There’s a lack of data in specific diseases to guide or examine what the role of TDM might be.”
In the meantime, no fewer than four clinical trials evaluating TDM with tumor necrosis factor (TNF) inhibitors in rheumatologic diseases are ongoing or have completed but not yet released results, according to Wallace. Three Adalimumab Drug Optimization in Rheumatoid Arthritis trials are underway: The first is evaluating drug tapering vs disease activity score; the second is testing low or usual drug concentration; and the third is studying switches to etanercept or a non-TNF inhibitor drug (abatacept, rituximab, tocilizumab, or sarilumab) in patients failing treatment. Another trial called Tocilizumab Drug Levels to Optimized Treatment in RA is randomizing patients with high drug levels to dose maintenance or dose reduction. All four trials are sponsored by the Reade Rheumatology Research Institute, Amsterdam, the Netherlands.
Until clearer answers emerge from clinical trials, a number of barriers to and questions about the potential for TDM in rheumatology persist.
Barriers to Wider Use of TDM
“The biggest barrier with TDM is simply just a lack of what to do with the data,” Balevic said. “The clinician needs clear-cut guidance on what to do with the drug level. So, in other words, what is the target concentration for the drug? And if that target is not the goal, how should that dose be adjusted?”
The optimal drug levels, particularly for the older conventional synthetic DMARDs, simply have not been validated by clinical trials, he said.
“Different studies may report different target drug levels, and this could be due to different underlying population, or a different matrix — a measure of whole blood vs plasma — or even the timing of the sample,” he said. Balevic led a pharmacokinetic study earlier this year that proposed an algorithm for determining the number of missed hydroxychloroquine doses.
“This really goes back to the clinician needing to draw on a lot of pharmacology training to interpret the literature,” Balevic added.
That gets to the need for more education among rheumatologists, as Brun pointed out. “The physician needs to be educated about therapeutic ranges, when to assess concentrations of drug antibodies, and how to react to the results,” Brun said.
Which ADAs to identify is also problematic. “For antidrug antibodies, it’s especially challenging because there are so many assay formats in use, and it’s a bit complicated to analyze these antidrug antibodies,” Brun said. “There’s no consensus on what calibrators to use, and there’s no standardization of how to report the results, so you can’t really compare results from different assays. You need to know what your laboratory is using and how to interpret results from that particular assay, so that’s a challenge.”
Variability in drug tolerance also exists across assays, Wallace noted. “One of the challenges that have come up in the discussion of therapeutic drug monitoring is understanding what the target level is,” he said. “Defining what the target level might be for a specific condition is not something that’s well understood.”
Breaking down the science, he noted that an ADA can bind to a monoclonal antibody, forming an immune complex that avoids detection. Drug-sensitive assays may detect high concentrations of ADAs but miss low or moderate concentrations. Drug-tolerant assays may be more likely to detect low concentrations at ADAs, but the clinical significance is unclear.
Cost and Patient Trust as Barriers
“The costs vary a lot from assay to assay,” Brun said. “Some commercial assays can be really expensive.” In Norway, a dedicated lab with its own in-house assays helps to keep costs down, she said.
But that’s not the case in the United States, where insurance coverage can be a question mark, Shivani Garg, MD, a rheumatologist at the University of Wisconsin (UW)-Madison and director of the UW-Madison Health Lupus and Lupus Nephritis Clinics, told Medscape Medical News. “A lot of insurances are covering therapeutic drug monitoring, but for the high-deductible plans, there should be a way to offer these important tests to patients at a lower cost or figure out a way for coverage for those patients so that they can show that there are benefits of therapeutic drug monitoring without being sent a really big bill,” she said.
Patient trust could be another potential barrier, Garg said. “A lot of times there is not shared decision-making involved in why this test is being done, how those tests will help us as clinicians, and [patients’ understanding of] the use of the medicine,” Garg said.
“If the shared decision-making to build trust is not there, a lot of times patients worry that they’re being under surveillance or they’re being watched, so that might add to the lack of trust in the core issues that are critical threats to patients with chronic diseases because this is a lifelong partnership,” she said.
Convenience is another issue. “Particularly with mycophenolate levels, a lot of studies have used area under the curve, so getting an area under the curve level over a period of 12 hours would require several samples,” Garg said.
Testing protocols are also uncertain, Garg added. “A few data points ... are missing, like how we use the data over time,” she said. “If you do it for a given patient over several years, how often should you do it? How often do the levels fluctuate? How are the data used to inform dosing changes or monitoring changes?
“When those pieces are put together, then we are more likely to build up an intervention that clinicians can use in clinical practice, so they know how to order it and how frequently do it — every 6 months, 3 months, or every month. And then, over a period of time, how to adjust the dosing. That’s the big question.”
Who May Benefit Most From TDM?
In the NOR-DRUM trials, patients at risk of developing ADA early on, before a disease flare or infusion reaction, seemed to benefit most from TDM. But who are those patients?
“We looked at risk factors for developing antidrug antibodies, and we found that patients with high disease activity when starting treatment, smokers, and patients with rheumatoid arthritis had a higher risk than other patients, as did patients who are not using concomitant immunosuppressive therapy,” Brun said.
“During treatment, we also found that low serum drug levels and drug holidays above 11 weeks were also risk factors,” she added.
The NOR-DRUM researchers also evaluated genetic risk factors and found that patients with the HLA-DQ2 gene variant were also at increased risk of developing ADA.
While NOR-DRUM evaluated only infliximab, some of its lessons may be applied to other DMARDs, Brun said. “We think that for other subcutaneously administered TNF inhibitors, you would probably see the same effect of proactive TDM, but we currently do not have data on that,” she said. A study similar to the NOR-DRUM design will evaluate this in Norway, Brun added.
She explained why the findings with infliximab may extend to adalimumab, which may be the second most immunogenic TNF inhibitor after infliximab. “The administration is different; it’s administered more often than infliximab; that would also make the results more uncertain to generalize to the other treatments, but I would guess there are also benefits of using TDM in other treatments.”
Potential Risks for TDM
Wallace has noted that TDM, with the current state of evidence, carries a number of potential risks. “The potential risks might be that you unnecessarily discontinue a medication because you detected an antibody, or the level seems low and you’re not able to get it higher, but the patient is otherwise doing fine,” he said. “You might end up increasing doses of the medicine that would put the patient at potentially increased risk of infection, as well as obviously more costs.”
That would also lead to more utilization of resources and costs, he said. “Some of those reasons are why there has been hesitation with therapeutic drug monitoring,” Wallace added.
A number of questions also surround the use of biosimilars and ADA levels, Wallace said. While a review of clinical trials found no meaningful differences in terms of immunogenicity between biosimilars and reference products, it did note discrepancies in how the agents were evaluated.
What DMARDs Are Most Suitable for TDM?
Petri said TDM would be useful for monitoring patients on mycophenolate mofetil. “A trough level can at least tell us if a patient is taking it,” she said. “Tacrolimus, used for lupus nephritis, has well-accepted peak and trough trends due to widespread use in transplant.”
Drugs with a wide variability in pharmacokinetics may also be suitable for TDM, Balevic said. That would include hydroxychloroquine, azathioprine, mycophenolate, or even cyclophosphamide. Drugs that have a narrow therapeutic index, such as tacrolimus, cyclosporine, or again, cyclophosphamide, might also be amenable to TDM, he said.
Why Do TDM?
“The two main reasons why somebody would go on to detect drug levels: The first may be to assess medication adherence, and this applies virtually to any drug that rheumatologists use; the second reason is to optimize dozing, either for efficacy purposes or to prevent toxicity,” Balevic said.
“When it comes to optimizing dosing, you should really think about TDM as one tool in our toolbelt,” he said.
Dose is “just a surrogate,” he said. “When we prescribe a drug, what truly matters is the amount of active unbound drug at the site of action. That’s what’s responsible for a drug’s pharmacologic effect.”
However, the same dose, or even the same weight-based dose, does not necessarily mean similar patients will achieve the same amount of exposure to the drug, but TDM can help determine that, he said.
What’s Next
Studies into the use of TDM in rheumatology are ongoing. Brun said her group is currently conducting a cost-effective analysis from the NOR-DRUM trials.
“There’s going to be more studies coming out in the next few years, looking at what impact the use of therapeutic drug monitoring might have on outcomes,” Wallace said.
“As we accumulate more and more evidence, we might see organizations like ACR and EULAR start to weigh in more on whether or not therapeutic drug monitoring can or should be used.”
Petri, Brun, and Garg had no relevant disclosures. Wallace disclosed financial relationships with Amgen, Alexion, BioCryst, Boehringer Ingelheim, Bristol Myers Squibb, Medpace, Novartis, Sanofi, Viela Bio, Visterra, Xencor, and Zenas. Balevic disclosed relationships with the National Institutes of Health, the Childhood Arthritis and Rheumatology Research Alliance, and UCB.

Therapeutic drug monitoring (TDM) — the practice of using laboratory testing to measure blood levels of drugs — has garnered growing interest among rheumatologists in managing patients on disease-modifying antirheumatic drugs (DMARDs), but that hasn’t exactly translated to widespread practice.
While TDM has made some inroads with patients taking monoclonal antibodies, specifically infliximab, its uptake has encountered a number of headwinds, not the least of which is a lack of evidence and clinical guidelines, uneven access and standards of assays, and even an uncertainty about how to interpret laboratory results.
“In some fields, such as neurology, TDM is accepted for antiepileptics,” Michelle Petri, MD, MPH, director of the Johns Hopkins Lupus Center, Baltimore, told Medscape Medical News. “In rheumatology, though, TDM is underutilized and not adequately championed by the American College of Rheumatology.”
She noted that TDM is most acutely needed for management of systemic lupus erythematosus, where nonadherence is a major problem. “Whole blood hydroxychloroquine monitoring has proven beneficial for identifying nonadherence, but also to pinpoint patients who are on too much, a risk factor for retinopathy,” Petri said.
“The state of therapeutic drug monitoring in general has been interesting when you think about its use in autoimmune disease because it’s very much used in gastroenterology and it’s been much less used in rheumatology,” Zachary Wallace, MD, codirector of the Rheumatology & Allergy Clinical Epidemiology Research Center at Massachusetts General Hospital in Boston, told Medscape Medical News. “Some of that may have to do with the interpretation of the availability of evidence, but I think it’s something clinicians will come across more and more often in their practice and wondering what its role might be,” he added.
The movement to precision medicine also portends to grow interest in TDM in rheumatology, said Stephen Balevic, MD, PhD, a rheumatologist and pharmacologist at Duke University and director of pharmacometrics at the Duke Clinical Research Institute, Durham, North Carolina.
“It’s a very exciting time for rheumatologists to begin thinking outside box on what it means to study precision medicine, and I think pharmacology is one of the most overlooked aspects of precision medicine in our community,” he told Medscape Medical News.
That may be because older DMARDs, namely hydroxychloroquine and methotrexate, came to market when regulatory requirements were different than they are today, Balevic said. “Many of the older conventional DMARDs were discovered incidentally and never really had the traditional pharmacokinetic-pharmacodynamic trials to determine optimal dosing, or perhaps that was extrapolated from other populations,” he said.
So, the “one-size-fits-all” approach does not work for prescribing older or even some of the newer DMARDs for rheumatologic disorders, Balevic said.
Reactive vs Proactive TDM
Among the few trials that examined TDM in rheumatology patients are the NOR-DRUM A and B trials in Norway. Marthe Brun, MD, PhD, a rheumatologist at the Center for Treatment of Rheumatic and Musculoskeletal Diseases at Diakonhjemmet Hospital in Oslo, Norway, and a coauthor of the NOR-DRUM trials, told Medscape Medical News that the trials found an overall benefit to TDM during infliximab maintenance therapy.

Brun’s group recently published an analysis of the trials. “We did not find an overall effect during the initial phase of the treatment, the first 30 weeks,” she told Medscape Medical News.
“Then we looked at subgroups, and we found that the patients that developed antidrug antibodies [ADAs] had an effect, and ADA are associated with poorer outcomes as well as infusion reactions for patients treated with infliximab.
“So, it’s probably a benefit to be able to detect these ADA early before the patient experiences a disease flare or infusion reaction,” Brun added. “It facilitates for the clinician to take action to, for example, increase the dosing or switch therapy.”
However, the quality of the data supporting TDM in rheumatology is limited, Balevic said. “There’s very good observational data, but we have very few clinical trials that actually leverage TDM,” he said.
NOR-DRUM is the exception, he said. “Ideally, we need more of these dose-optimization trials to help guide clinical practice,” he said. But it stands alone.
Wallace noted several take-home messages from the NOR-DRUM trials, namely that using TDM to prevent ADA may be more effective during the maintenance phase of treatment than the induction phase. However, he said, the evidence is still emerging.
“It’s reasonable to say that we’re at an early stage of the evidence,” he said. “If you look at the large trials that have been done in rheumatology, they’ve combined patients with many different types of conditions, and a lot of our recommendations in rheumatology are disease-specific — in rheumatoid arthritis, in vasculitis. There’s a lack of data in specific diseases to guide or examine what the role of TDM might be.”
In the meantime, no fewer than four clinical trials evaluating TDM with tumor necrosis factor (TNF) inhibitors in rheumatologic diseases are ongoing or have completed but not yet released results, according to Wallace. Three Adalimumab Drug Optimization in Rheumatoid Arthritis trials are underway: The first is evaluating drug tapering vs disease activity score; the second is testing low or usual drug concentration; and the third is studying switches to etanercept or a non-TNF inhibitor drug (abatacept, rituximab, tocilizumab, or sarilumab) in patients failing treatment. Another trial called Tocilizumab Drug Levels to Optimized Treatment in RA is randomizing patients with high drug levels to dose maintenance or dose reduction. All four trials are sponsored by the Reade Rheumatology Research Institute, Amsterdam, the Netherlands.
Until clearer answers emerge from clinical trials, a number of barriers to and questions about the potential for TDM in rheumatology persist.
Barriers to Wider Use of TDM
“The biggest barrier with TDM is simply just a lack of what to do with the data,” Balevic said. “The clinician needs clear-cut guidance on what to do with the drug level. So, in other words, what is the target concentration for the drug? And if that target is not the goal, how should that dose be adjusted?”
The optimal drug levels, particularly for the older conventional synthetic DMARDs, simply have not been validated by clinical trials, he said.
“Different studies may report different target drug levels, and this could be due to different underlying population, or a different matrix — a measure of whole blood vs plasma — or even the timing of the sample,” he said. Balevic led a pharmacokinetic study earlier this year that proposed an algorithm for determining the number of missed hydroxychloroquine doses.
“This really goes back to the clinician needing to draw on a lot of pharmacology training to interpret the literature,” Balevic added.
That gets to the need for more education among rheumatologists, as Brun pointed out. “The physician needs to be educated about therapeutic ranges, when to assess concentrations of drug antibodies, and how to react to the results,” Brun said.
Which ADAs to identify is also problematic. “For antidrug antibodies, it’s especially challenging because there are so many assay formats in use, and it’s a bit complicated to analyze these antidrug antibodies,” Brun said. “There’s no consensus on what calibrators to use, and there’s no standardization of how to report the results, so you can’t really compare results from different assays. You need to know what your laboratory is using and how to interpret results from that particular assay, so that’s a challenge.”
Variability in drug tolerance also exists across assays, Wallace noted. “One of the challenges that have come up in the discussion of therapeutic drug monitoring is understanding what the target level is,” he said. “Defining what the target level might be for a specific condition is not something that’s well understood.”
Breaking down the science, he noted that an ADA can bind to a monoclonal antibody, forming an immune complex that avoids detection. Drug-sensitive assays may detect high concentrations of ADAs but miss low or moderate concentrations. Drug-tolerant assays may be more likely to detect low concentrations at ADAs, but the clinical significance is unclear.
Cost and Patient Trust as Barriers
“The costs vary a lot from assay to assay,” Brun said. “Some commercial assays can be really expensive.” In Norway, a dedicated lab with its own in-house assays helps to keep costs down, she said.
But that’s not the case in the United States, where insurance coverage can be a question mark, Shivani Garg, MD, a rheumatologist at the University of Wisconsin (UW)-Madison and director of the UW-Madison Health Lupus and Lupus Nephritis Clinics, told Medscape Medical News. “A lot of insurances are covering therapeutic drug monitoring, but for the high-deductible plans, there should be a way to offer these important tests to patients at a lower cost or figure out a way for coverage for those patients so that they can show that there are benefits of therapeutic drug monitoring without being sent a really big bill,” she said.
Patient trust could be another potential barrier, Garg said. “A lot of times there is not shared decision-making involved in why this test is being done, how those tests will help us as clinicians, and [patients’ understanding of] the use of the medicine,” Garg said.
“If the shared decision-making to build trust is not there, a lot of times patients worry that they’re being under surveillance or they’re being watched, so that might add to the lack of trust in the core issues that are critical threats to patients with chronic diseases because this is a lifelong partnership,” she said.
Convenience is another issue. “Particularly with mycophenolate levels, a lot of studies have used area under the curve, so getting an area under the curve level over a period of 12 hours would require several samples,” Garg said.
Testing protocols are also uncertain, Garg added. “A few data points ... are missing, like how we use the data over time,” she said. “If you do it for a given patient over several years, how often should you do it? How often do the levels fluctuate? How are the data used to inform dosing changes or monitoring changes?
“When those pieces are put together, then we are more likely to build up an intervention that clinicians can use in clinical practice, so they know how to order it and how frequently do it — every 6 months, 3 months, or every month. And then, over a period of time, how to adjust the dosing. That’s the big question.”
Who May Benefit Most From TDM?
In the NOR-DRUM trials, patients at risk of developing ADA early on, before a disease flare or infusion reaction, seemed to benefit most from TDM. But who are those patients?
“We looked at risk factors for developing antidrug antibodies, and we found that patients with high disease activity when starting treatment, smokers, and patients with rheumatoid arthritis had a higher risk than other patients, as did patients who are not using concomitant immunosuppressive therapy,” Brun said.
“During treatment, we also found that low serum drug levels and drug holidays above 11 weeks were also risk factors,” she added.
The NOR-DRUM researchers also evaluated genetic risk factors and found that patients with the HLA-DQ2 gene variant were also at increased risk of developing ADA.
While NOR-DRUM evaluated only infliximab, some of its lessons may be applied to other DMARDs, Brun said. “We think that for other subcutaneously administered TNF inhibitors, you would probably see the same effect of proactive TDM, but we currently do not have data on that,” she said. A study similar to the NOR-DRUM design will evaluate this in Norway, Brun added.
She explained why the findings with infliximab may extend to adalimumab, which may be the second most immunogenic TNF inhibitor after infliximab. “The administration is different; it’s administered more often than infliximab; that would also make the results more uncertain to generalize to the other treatments, but I would guess there are also benefits of using TDM in other treatments.”
Potential Risks for TDM
Wallace has noted that TDM, with the current state of evidence, carries a number of potential risks. “The potential risks might be that you unnecessarily discontinue a medication because you detected an antibody, or the level seems low and you’re not able to get it higher, but the patient is otherwise doing fine,” he said. “You might end up increasing doses of the medicine that would put the patient at potentially increased risk of infection, as well as obviously more costs.”
That would also lead to more utilization of resources and costs, he said. “Some of those reasons are why there has been hesitation with therapeutic drug monitoring,” Wallace added.
A number of questions also surround the use of biosimilars and ADA levels, Wallace said. While a review of clinical trials found no meaningful differences in terms of immunogenicity between biosimilars and reference products, it did note discrepancies in how the agents were evaluated.
What DMARDs Are Most Suitable for TDM?
Petri said TDM would be useful for monitoring patients on mycophenolate mofetil. “A trough level can at least tell us if a patient is taking it,” she said. “Tacrolimus, used for lupus nephritis, has well-accepted peak and trough trends due to widespread use in transplant.”
Drugs with a wide variability in pharmacokinetics may also be suitable for TDM, Balevic said. That would include hydroxychloroquine, azathioprine, mycophenolate, or even cyclophosphamide. Drugs that have a narrow therapeutic index, such as tacrolimus, cyclosporine, or again, cyclophosphamide, might also be amenable to TDM, he said.
Why Do TDM?
“The two main reasons why somebody would go on to detect drug levels: The first may be to assess medication adherence, and this applies virtually to any drug that rheumatologists use; the second reason is to optimize dozing, either for efficacy purposes or to prevent toxicity,” Balevic said.
“When it comes to optimizing dosing, you should really think about TDM as one tool in our toolbelt,” he said.
Dose is “just a surrogate,” he said. “When we prescribe a drug, what truly matters is the amount of active unbound drug at the site of action. That’s what’s responsible for a drug’s pharmacologic effect.”
However, the same dose, or even the same weight-based dose, does not necessarily mean similar patients will achieve the same amount of exposure to the drug, but TDM can help determine that, he said.
What’s Next
Studies into the use of TDM in rheumatology are ongoing. Brun said her group is currently conducting a cost-effective analysis from the NOR-DRUM trials.
“There’s going to be more studies coming out in the next few years, looking at what impact the use of therapeutic drug monitoring might have on outcomes,” Wallace said.
“As we accumulate more and more evidence, we might see organizations like ACR and EULAR start to weigh in more on whether or not therapeutic drug monitoring can or should be used.”
Petri, Brun, and Garg had no relevant disclosures. Wallace disclosed financial relationships with Amgen, Alexion, BioCryst, Boehringer Ingelheim, Bristol Myers Squibb, Medpace, Novartis, Sanofi, Viela Bio, Visterra, Xencor, and Zenas. Balevic disclosed relationships with the National Institutes of Health, the Childhood Arthritis and Rheumatology Research Alliance, and UCB.

Pediatric Myasthenia Gravis: Don’t Treat Children Like Adults
SAVANNAH, GEORGIA — At a pathophysiological level, juvenile myasthenia gravis (MG) seems to be identical to the adult form, neuromuscular specialists learned. But there are still important differences between children and their elders that affect pediatric care.
For example, “we have to think a little bit differently about the side effect profiles of the medications and their toxicity because children may react to medications differently,” said Matthew Ginsberg, MD, a pediatric neurologist based in Akron, Ohio, in a presentation at the American Association of Neuromuscular & Electrodiagnostic Medicine (AANEM) 2024.
And then there’s the matter of adherence. “It’s hard to get adults to take medication, but a teenager is sometimes an exceptional challenge,” Ginsberg said.
Case In Point: A 13-Year-Old With MG
Pediatric MG is rare. Cases in children are estimated to account for 10% of MG cases diagnosed each year. According to a 2020 report, “the majority will present with ptosis and a variable degree of ophthalmoplegia [paralysis of eye muscles].”
Ginsberg highlighted a case of a 13-year-old girl who’d been healthy but developed fatigable ptosis and mild restriction of extraocular movements. The patient’s acetylcholine receptor antibodies were very elevated, but she didn’t have MuSK antibodies.
“This isn’t a diagnostic conundrum. She has autoimmune myasthenia gravis with ocular manifestations,” Ginsberg said. “For someone like this, whether it’s an adult or a child, many people would start symptomatic treatment with an acetylcholinesterase inhibitor like pyridostigmine.”
The use of the drug in children is similar to that in adults, he said, although weight-based dosing is used. “Usually it’s around 3-7 mg/kg/d, but it’s still very individualized based on patient response.” The timing of symptoms can affect the distribution of doses throughout the day, he said.
“There are extended-release formulations of the medication, and I think some people use them more than I do,” he said. “The side effects are basically similar to adults. Most of the patients I have on it tolerate it really well and don’t have a lot of the muscarinic side effects that you would expect.”
Consider Prescription Eye Drops for Ptosis
Alpha-1A agonists oxymetazoline and apraclonidine in the form of topical eye drops can help with ptosis. “They potentially avoid some of the systemic toxicity of the other medications,” Ginsberg said. “So they might be an option if you’re really just trying to target ptosis as a symptom.”
However, it can be difficult to get insurers to cover these medications, he said.
The 13-year-old patient initially improved but developed difficulty walking. “Her hands began to feel heavy, and she had difficulty chewing and nasal regurgitation. On her exam, she still had fatigable ptosis plus hypernasal speech and generalized weakness. At this point, we’re starting to see that she has generalized myasthenia gravis that may be an impending crisis.”
The Young Patient Worsens. Now What?
The patient was admitted and given intravenous immunoglobulin at 2 g/kg over a couple days. But her symptoms worsened following initial improvement.
Glucocorticoids can play a larger role in treatment at this stage, and the patient was initially on prednisone. But there are reasons for caution, including effects on bone growth and interference with live vaccines.
However, live vaccines aren’t common in children, with the exception of the MMRV vaccine, he said. “It’s worth noting that you can give that second dose as early as 3 months after the initial one, so most patients really should be able to complete a course before they start on immunosuppression,” he said.
Another option is immunotherapy. “There’s a really large menu of options for immunotherapy in myasthenia gravis right now,” Ginsberg said. “It’s great that we have all these options, but it adds to the complexity.”
Rituximab may be considered based on early data, he said. And thymectomy — removal of the thymus gland — should be considered early.
Don’t Neglect Supportive Care
Ginsberg urged colleagues to consider supportive care measures. Advocacy groups such as the Myasthenia Gravis Foundation of America can help with weight management and diet/exercise counseling, especially in patients taking glucocorticoids.
He added that “school accommodations are very important in this age group. They might need a plan, for example, to have modified gym class or an excuse not to carry a book bag between classes.”
How did the 13-year-old do? She underwent thymectomy, and her disease remained stable after 6 months. “Her rituximab was discontinued,” Ginsberg said. “She considered participating in a clinical trial but then started seeing improvements. About a year after the thymectomy, she just stopped her steroids on her own, and she was fine.”
Ginsberg had no disclosures.

EHR Prompt Helped Cut Acute Otitis Media Antibiotic Use by Half
LOS ANGELES — Embedding a new discharge order set into electronic health records (EHRs) with a preselected 5-day antibiotic course for children aged 2 years or older diagnosed with acute otitis media (AOM) cut antibiotic duration sharply, according to new data presented at the Infectious Disease Week (IDWeek) 2024 Annual Meeting.
“We were effectively able to cut antibiotic use in half by shortening the duration of treatment,” said lead author Joana Dimo, DO, a Pediatric Infectious Diseases fellow at the University of Colorado Denver/Children’s Hospital Colorado.
In the United States, 80% of children will experience otitis media during their lifetime. Untreated ear infections can lead to symptoms ranging from mild ear discharge to life-threatening conditions such as mastoiditis and intracranial abscesses.
Most Cases Resolve Without Antibiotics
Ear infections “are the leading reason for antibiotic prescriptions in kids,” Dimo noted, adding that 24% of all pediatric antibiotic prescriptions are for AOM. Amoxicillin is the preferred first-line treatment. “Research supports that 75% of children get better on their own without antibiotics, and when needed, short courses of just 5 days are safe and effective.”
Antibiotics can cause side effects such as diarrhea and rashes. “Each additional day of antibiotics that are not needed leads to more side effects,” Dimo said, as well as contributing to antibiotic resistance.
Dimo’s team implemented new EHR order sets across the University of Colorado/Children’s Hospital Colorado health network’s four emergency departments and four urgent care centers and included 31,929 patients in the study.
Then they conducted a retrospective review of patients 61 days to 18 years old who entered those settings and had confirmed AOM between January 2019 through December 2023, before and after the April 2021 intervention. The researchers also developed a guideline on managing ear infections to support clinicians as part of the intervention in December 2022.
Compliance Grew From 3% to 83%
Dimo said they found very few clinicians in their study had been prescribing according to current guidelines. Their results showed a jump from 3% to 83% in providers prescribing 5-day durations of antibiotics for children aged 2 years or older after their intervention.
The intervention did not lead to increased treatment failures or complications, she added. The team looked for diagnostic codes for mastoiditis, subperiosteal abscess, petrositis, labyrinthitis, meningitis, and intracranial abscess, and “none of our patients” developed any of those complications, Dimo said.
Dimo said the overall rate of prescribing, however, increased. Finding out why prescribing rates remained high throughout the study, before and after their intervention, is a question they are investigating in future work, she said.
Cost-Effective and Scalable
“The benefit of this strategy to other institutions is that it’s not labor-intensive. It’s cost-effective, and it can result in dramatic changes in antibiotic use,” Dimo said.
“In the outpatient setting, there’s still a lot of antibiotics being given unnecessarily to children with acute otitis media,” said William Schaffner, MD, infectious disease specialist at Vanderbilt University School of Medicine in Nashville, Tennessee, who was not part of the research. “The American Academy of Pediatrics has been working on that for about a decade — to get pediatricians attuned to when you use them. Most of these episodes of acute otitis media — it’s now well-established — are due to viral infections.”
He said that some physicians may still be defaulting to the longer doses — up to 10 days — that they may have learned in medical school or residency.
“The data would indicate that 5 days of treatment — when treatment is appropriate — is, in the vast majority of instances, sufficient,” Schaffner said.
The researchers “were remarkably successful,” he said, adding that another question is ripe for research. “They still have to get to this issue of whether all of these antibiotic starts were necessary.”
Not knowing whether antibiotic prescriptions in this study were warranted is a limitation of the study, Dimo said, as was not being able to track whether patients presented to institutions outside their own for a return visit or for complications.
She said she thinks one of the reasons for such a sharp increase in compliance was that clinicians in their system routinely use order sets, so using the new order sets easily became part of their workflow.
Dimo and Schaffner reported no relevant financial relationships.

She said she thinks one of the reasons for such a sharp increase in compliance was that clinicians in their system routinely use order sets, so using the new order sets easily became part of their workflow.

LOS ANGELES — Embedding a new discharge order set into electronic health records (EHRs) with a preselected 5-day antibiotic course for children aged 2 years or older diagnosed with acute otitis media (AOM) cut antibiotic duration sharply, according to new data presented at the Infectious Disease Week (IDWeek) 2024 Annual Meeting.
“We were effectively able to cut antibiotic use in half by shortening the duration of treatment,” said lead author Joana Dimo, DO, a Pediatric Infectious Diseases fellow at the University of Colorado Denver/Children’s Hospital Colorado.
In the United States, 80% of children will experience otitis media during their lifetime. Untreated ear infections can lead to symptoms ranging from mild ear discharge to life-threatening conditions such as mastoiditis and intracranial abscesses.
Most Cases Resolve Without Antibiotics
Ear infections “are the leading reason for antibiotic prescriptions in kids,” Dimo noted, adding that 24% of all pediatric antibiotic prescriptions are for AOM. Amoxicillin is the preferred first-line treatment. “Research supports that 75% of children get better on their own without antibiotics, and when needed, short courses of just 5 days are safe and effective.”
Antibiotics can cause side effects such as diarrhea and rashes. “Each additional day of antibiotics that are not needed leads to more side effects,” Dimo said, as well as contributing to antibiotic resistance.
Dimo’s team implemented new EHR order sets across the University of Colorado/Children’s Hospital Colorado health network’s four emergency departments and four urgent care centers and included 31,929 patients in the study.
Then they conducted a retrospective review of patients 61 days to 18 years old who entered those settings and had confirmed AOM between January 2019 through December 2023, before and after the April 2021 intervention. The researchers also developed a guideline on managing ear infections to support clinicians as part of the intervention in December 2022.
Compliance Grew From 3% to 83%
Dimo said they found very few clinicians in their study had been prescribing according to current guidelines. Their results showed a jump from 3% to 83% in providers prescribing 5-day durations of antibiotics for children aged 2 years or older after their intervention.
The intervention did not lead to increased treatment failures or complications, she added. The team looked for diagnostic codes for mastoiditis, subperiosteal abscess, petrositis, labyrinthitis, meningitis, and intracranial abscess, and “none of our patients” developed any of those complications, Dimo said.
Dimo said the overall rate of prescribing, however, increased. Finding out why prescribing rates remained high throughout the study, before and after their intervention, is a question they are investigating in future work, she said.
Cost-Effective and Scalable
“The benefit of this strategy to other institutions is that it’s not labor-intensive. It’s cost-effective, and it can result in dramatic changes in antibiotic use,” Dimo said.
“In the outpatient setting, there’s still a lot of antibiotics being given unnecessarily to children with acute otitis media,” said William Schaffner, MD, infectious disease specialist at Vanderbilt University School of Medicine in Nashville, Tennessee, who was not part of the research. “The American Academy of Pediatrics has been working on that for about a decade — to get pediatricians attuned to when you use them. Most of these episodes of acute otitis media — it’s now well-established — are due to viral infections.”
He said that some physicians may still be defaulting to the longer doses — up to 10 days — that they may have learned in medical school or residency.
“The data would indicate that 5 days of treatment — when treatment is appropriate — is, in the vast majority of instances, sufficient,” Schaffner said.
The researchers “were remarkably successful,” he said, adding that another question is ripe for research. “They still have to get to this issue of whether all of these antibiotic starts were necessary.”

FROM IDWEEK 2024
Chronic Cough in Children: Identifying Common and Uncommon Causes
ORLANDO, FLORIDA — , according to Rajeev Bhatia, MD, division chief of pulmonology at Phoenix Children’s in Phoenix, Arizona. Bhatia reviewed both the major causes of chronic cough as well as the rare zebras to watch out for in a presentation at the American Academy of Pediatrics (AAP) 2024 National Conference.
“When you see a patient for cough, the most important thing is, history, history, history,” Bhatia said. “There are many, many, many clues in the history, age of onset, and duration.” That includes starting at birth to ensure you don’t miss key details such as a preterm birth. It’s also important to discuss what the cough sounds like, how frequent it is, what makes it better, what makes it worse, and how it’s affecting the child and others around them — all of which can help narrow the diagnosis.
Jose Quijada, DO, a pediatrician with CommuniCare Pediatrics in San Antonio, found the session “incredibly useful” not only because of the specific pointers about each condition but also because of the realistic case studies he included throughout.
“Sometimes when you’re practicing, you focus on what’s most common,” Quijada said, so it was helpful to get a review of some of the key features and red flags that point to less common causes that may need to be considered. He particularly appreciated the discussion of habitual cough and potential treatments because those can be challenging patients and it can be tough to find a middle ground with how much workup to do.
Common Causes of Chronic Cough
The coughing from inadequately controlled asthma tends to be nonproductive and worse at night or in the early morning, Bhatia explained, and it’s often accompanied by wheezing, shortness of breath, and chest tightness. While fractional exhaled nitric oxide can be useful, “studies show that it is more useful for to monitor the symptoms rather than to diagnose the asthma,” Bhatia told attendees, but he also added that spirometry can be normal in patients with asthma. In young patients, the Asthma Predictive Index can be an invaluable tool, he also said.
Another common cause of chronic cough is a postinfectious cough, which lasts more than 3 weeks after resolution of acute upper respiratory infection. It occurs in about one in 10 children after a viral infection such as a rhinovirus or respiratory syncytial virus infection and results from extensive inflammation and disruption of the airway epithelial integrity. Chest x-rays are usually normal in these patients, and the cough will usually resolve on its own. Albuterol has not been shown to be any more effective than placebo for a postinfectious cough, and antibiotics similarly have no clinically useful role.
A wet cough that lasts for at least 4 weeks and appears to have no other specific cause may be protracted bacterial bronchitis (PBB). While the cause of PBB isn’t known, it could be due to frequent illnesses that cause airway inflammation and injury over time, thereby making it easier for bacteria to grow and cause infection. Risk factors include tracheomalacia/bronchomalacia and childcare attendance, and typical pathogens include Haemophilus influenzae, Streptococcus pneumonia, and Moraxella catarrhalis.
While an x-ray can be done, radiography is often normal in patients with PBB. Bronchoscopy will reveal purulent secretions. PBB should resolve with at least 2 weeks of antibiotics, including amoxicillin-clavulanate, but the course can be extended to 4 weeks if the cough persists. However, about 40% of patients will have recurrence, and those with recurrent PBB or with a chronic cough unresponsive to 4 weeks of antibiotics should be referred to a pediatric pulmonologist.
Upper airway cough syndrome is the updated name for postnasal drip, which can occur with both allergic and nonallergic rhinitis and chronic rhinosinusitis. This is often a dry, throat-clearing cough that can be accompanied by headaches, nasal congestion, and sinus or facial tenderness. An examination will reveal posterior pharynx cobblestoning, Bhatia said, and empirical use of intranasal steroids can be both diagnostic and therapeutic for upper airway cough syndrome. He also emphasized the importance of taking an environmental history and avoiding exposure of environmental triggers.
Uncommon Pulmonary Causes of Chronic Cough
After discussing frequent reasons patients may present with a chronic cough, Bhatia went on to discuss the less common things to consider if the provider has eliminated the other possibilities. These include both pulmonary causes as well as congenital malformations, gastrointestinal causes, and habit cough.
A child who presents with a sudden onset of cough or wheeze in the absence of an upper respiratory infection may have a retained foreign body. This cough can be mistaken for bronchiolitis, asthma, croup, and other infectious conditions, especially because a partial obstruction can make diagnosis confusing or challenging. Adding to the challenge is that most foreign bodies will be radiolucent. A decubitus chest x-ray could be useful, but bronchoscopy is necessary for diagnosis. Bhatia stressed that it’s easy to miss a foreign body in younger children and that the wheezing can be more prominent on one side or another.
Cystic fibrosis, another uncommon cause of chronic cough, is ideally diagnosed via newborn screening, but screening is imperfect and can involve missed diagnoses or false negatives. Over 75% of cystic fibrosis cases are diagnosed by age 2, but that means a substantial number of cases still are not diagnosed until older childhood or later. This cough will be a chronic productive/wet cough.
A family history of cystic fibrosis may be present but doesn’t have to be, so signs to look for include poor weight gain, sinusitis, nasal polyps, clubbing, and isolation of suspicious organisms from a respiratory culture, such as Pseudomonas aeruginosa or Burkholderia cepacia complex. Clubbing in the fingers is a particularly telltale symptom of undiagnosed cystic fibrosis, and bronchiectasis of unknown etiology will be present. Suspicion of cystic fibrosis should lead to a referral to a cystic fibrosis center for a sweat test.
Even rarer than cystic fibrosis is primary ciliary dyskinesia (PCD), an inherited autosomal recessive disease that occurs in about one in 20,000 live births and involves a structural or functional defect in the cilia. About half of all patients with PCD will have situs inversus — an arrangement of chest and abdominal organs that is a mirror image of typical human anatomical presentation — but most people with situs inversus do not have PCD. One type of PCD is Kartagener syndrome, identified by the triad of situs inversus totalis, chronic sinusitis, and bronchiectasis.
Children with PCD present with a chronic productive cough and recurrent pneumonias, and nearly all patients will have rhinosinusitis. About 60% of patients will develop respiratory symptoms such as mild distress or cough in their first month, and recurrent otitis media is common in these patients. PCD diagnosis is based on a combination of genetic testing, nasal nitric oxide, and evaluation of ciliary motion and structure. Clinical suspicion of PCD should lead to a specialist referral.
Nearly all people with PCD will eventually develop bronchiectasis, where the priority should be airway clearance using antibiotics for acute exacerbations and chronic azithromycin therapy for recurrent exacerbations. Patients with chronic rhinosinusitis, chronic otitis media, and nasal polyposis should be referred to an ENT specialist.
Other Uncommon Causes of Chronic Cough
A non-pulmonary, uncommon cause of chronic cough is a vascular ring, a congenital anomaly in which blood vessels encircle and potentially constrict the esophagus and/or trachea. The most common type is a double aortic arch, but a right aortic arch or pulmonary artery sling is also possible. These coughs sound harsh and are usually accompanied by stridor, dyspnea and feeding problems. Workup includes an echocardiogram, a CT angiogram, and possibly a bronchoscopy to determine the extent of the airway narrowing. In symptomatic patients, surgery is indicated for correction.
Another congenital malformation that can cause chronic cough is a tracheoesophageal fistula, which occurs in about one in 3500 live births, commonly linked to trisomy disorders and VACTERL. Several types of tracheoesophageal fistula exist, and H-type fistula is associated with late onset symptoms. The cough can be wet or dry and sometimes sounds like barking because of the associated airway collapse. Patients often have recurrent pneumonia, bronchitis, and cough or cyanosis with feeding. Workup should include an upper gastrointestinal series but not with barium, Bhatia said, because that can cause pneumonitis. Instead, the series should be done with a thickened water-soluble contrast material, and a bronchoscopy may be indicated as well.
Though common as a condition in adults, gastroesophageal reflux disease (GERD) is a rare, but possible, cause of chronic cough in children. More often, the reflux is the result of the cough rather than the cause. The most sensitive tool for assessing GERD is esophageal 24-hour pH/impedance reflux monitoring. However, treatment of the reflux for cough is not recommended unless the patient has clinical features of GERD, including dystonic neck posturing in infants, heartburn, regurgitation, or other symptoms. If the patient has clinical symptoms, then treatment is acid suppressive therapy for 4-8 weeks, followed by a clinical reassessment.
An uncommon cause of chronic cough with no biological mechanism is habit cough. Habit cough is most easily distinguished from other coughs by its sounds, a “large, loud, honking noise,” Bhatia said. It also lacks a clear trigger and is usually absent during sleep, but it can be continuous during the day. Frustratingly, the patients themselves often don’t seem bothered by the cough, but “it’s very disruptive in the school and everywhere else,” Bhatia said. Families and/providers will often have tried multiple treatments and seen no improvement with habit cough.
The first thing to do with habit cough is reassure the family that there’s nothing serious going on because they are often worried by this point. Several non-pharmaceutical treatments can be effective, such as suggestion therapy or the “warm water technique,” in which the patient takes a sip of warm water every time they feel the urge to cough. “If they’re able to break the cycle, most of the time, they are fine,” Bhatia said. In rarer cases, more involved behavioral interventions may be indicated, such as a psychology referral if an underlying anxiety or other behavioral disorder is contributing.
Newer Causes of Cough
Two more recent causes of cough to watch for are long COVID and e-cigarette or vaping product–associated lung injury (EVALI), Bhatia said. The clearest sign of EVALI is a history of e-cigarette/vaping exposure, but clinical symptoms include a dry cough that occurs with dyspnea and chest pain. A chest x-ray may show diffuse, hazy, or consolidative opacities. Sometimes antibiotics or steroids can be helpful, but the evidence isn’t strong, and the most effective treatment is stopping e-cigarette use. Less commonly, passive exposure to vaping can also be associated with EVALI.
The most recent research on long COVID suggests that about 10-20% of children with acute COVID develop long COVID, and about a quarter of these patients develop a chronic dry cough. It’s often associated with fatigue and shortness of breath, which can be assessed with cardiopulmonary exercise testing. Sometimes a short trial of inhaled steroids can help.
Bhatia also mentioned a handful of other uncommon causes of chronic cough that most American pediatricians are unlikely to see: Childhood interstitial lung disease, tuberculosis, use of Angiotensin-Converting Enzyme inhibitors, and a build-up of ear wax via the Arnold’s nerve reflex.
Evaluation and Workup
Bhatia also discussed what to cover while taking a history and questions to ask. The history should include the type of cough, the onset timing (sudden vs gradual), associated symptoms, the cough trajectory, medications the patient is taking, and the patient’s past medical history and environmental exposures. Those attributes are included in this more comprehensive list of questions to consider during evaluation, adapted from a list provided in a 2019 article in Paediatric Respiratory Reviews:
- Age of onset and duration?
- Was the onset sudden or associate with an illness?
- Is the cough wet or dry?
- What does the cough sound like?
- How often does the cough occur?
- Is it progressive?
- Is it present during sleep?
- Are there any other associated symptoms, such as wheeze, dyspnea, vomiting, chest pain, etc?
- Are there any exacerbating factors or known triggers?
- Are there any relieving factors, including a trial of bronchodilators?
- Has there been exposure to auto-irritants, such as secondhand smoke?
- What is the cough’s effect on the child and on others around the child?
- Does the child have any other underlying conditions such as neuromuscular disease or asthma?
- What medications is the child taking or has recently taken?
- Is there a family history of atopy and/or respiratory disease?
Bhatia also recommended paying special attention to the following red flags or key features that may help more quickly narrow the diagnosis and often require a specialist referral:
- Digital clubbing, failure to thrive, or low tone
- An abnormal cardiac exam
- Tachypnea, hypoxemia, chest retractions, or hemoptysis
- Abnormal breath sounds such as unilateral wheezing or coarse crackles
- Abnormal spirometry in those aged 5 and older showing reversible obstruction, which often indicates asthma
- An abnormal chest x-ray with, for example, bilateral infiltrates, hyperinflation, right middle lobe syndrome, situs inversus, unilateral hyperlucency, a right aortic arch, etc.
No external funding was used for the presentation. Bhatia and Quijada had no disclosures.

This is often a dry, throat-clearing cough that can be accompanied by headaches, nasal congestion, and sinus or facial tenderness. An examination will reveal posterior pharynx cobblestoning, Bhatia said, and empirical use of intranasal steroids can be both diagnostic and therapeutic for upper airway cough syndrome. He also emphasized the importance of taking an environmental history and avoiding exposure of environmental triggers.
Uncommon Pulmonary Causes of Chronic Cough
After discussing frequent reasons patients may present with a chronic cough, Bhatia went on to discuss the less common things to consider if the provider has eliminated the other possibilities. These include both pulmonary causes as well as congenital malformations, gastrointestinal causes, and habit cough.
A child who presents with a sudden onset of cough or wheeze in the absence of an upper respiratory infection may have a retained foreign body. This cough can be mistaken for bronchiolitis, asthma, croup, and other infectious conditions, especially because a partial obstruction can make diagnosis confusing or challenging. Adding to the challenge is that most foreign bodies will be radiolucent. A decubitus chest x-ray could be useful, but bronchoscopy is necessary for diagnosis. Bhatia stressed that it’s easy to miss a foreign body in younger children and that the wheezing can be more prominent on one side or another.
Cystic fibrosis, another uncommon cause of chronic cough, is ideally diagnosed via newborn screening, but screening is imperfect and can involve missed diagnoses or false negatives. Over 75% of cystic fibrosis cases are diagnosed by age 2, but that means a substantial number of cases still are not diagnosed until older childhood or later. This cough will be a chronic productive/wet cough.
A family history of cystic fibrosis may be present but doesn’t have to be, so signs to look for include poor weight gain, sinusitis, nasal polyps, clubbing, and isolation of suspicious organisms from a respiratory culture, such as Pseudomonas aeruginosa or Burkholderia cepacia complex. Clubbing in the fingers is a particularly telltale symptom of undiagnosed cystic fibrosis, and bronchiectasis of unknown etiology will be present. Suspicion of cystic fibrosis should lead to a referral to a cystic fibrosis center for a sweat test.
Even rarer than cystic fibrosis is primary ciliary dyskinesia (PCD), an inherited autosomal recessive disease that occurs in about one in 20,000 live births and involves a structural or functional defect in the cilia. About half of all patients with PCD will have situs inversus — an arrangement of chest and abdominal organs that is a mirror image of typical human anatomical presentation — but most people with situs inversus do not have PCD. One type of PCD is Kartagener syndrome, identified by the triad of situs inversus totalis, chronic sinusitis, and bronchiectasis.
Children with PCD present with a chronic productive cough and recurrent pneumonias, and nearly all patients will have rhinosinusitis. About 60% of patients will develop respiratory symptoms such as mild distress or cough in their first month, and recurrent otitis media is common in these patients. PCD diagnosis is based on a combination of genetic testing, nasal nitric oxide, and evaluation of ciliary motion and structure. Clinical suspicion of PCD should lead to a specialist referral.
Nearly all people with PCD will eventually develop bronchiectasis, where the priority should be airway clearance using antibiotics for acute exacerbations and chronic azithromycin therapy for recurrent exacerbations. Patients with chronic rhinosinusitis, chronic otitis media, and nasal polyposis should be referred to an ENT specialist.
Other Uncommon Causes of Chronic Cough
A non-pulmonary, uncommon cause of chronic cough is a vascular ring, a congenital anomaly in which blood vessels encircle and potentially constrict the esophagus and/or trachea. The most common type is a double aortic arch, but a right aortic arch or pulmonary artery sling is also possible. These coughs sound harsh and are usually accompanied by stridor, dyspnea and feeding problems. Workup includes an echocardiogram, a CT angiogram, and possibly a bronchoscopy to determine the extent of the airway narrowing. In symptomatic patients, surgery is indicated for correction.
Another congenital malformation that can cause chronic cough is a tracheoesophageal fistula, which occurs in about one in 3500 live births, commonly linked to trisomy disorders and VACTERL. Several types of tracheoesophageal fistula exist, and H-type fistula is associated with late onset symptoms. The cough can be wet or dry and sometimes sounds like barking because of the associated airway collapse. Patients often have recurrent pneumonia, bronchitis, and cough or cyanosis with feeding. Workup should include an upper gastrointestinal series but not with barium, Bhatia said, because that can cause pneumonitis. Instead, the series should be done with a thickened water-soluble contrast material, and a bronchoscopy may be indicated as well.
Though common as a condition in adults, gastroesophageal reflux disease (GERD) is a rare, but possible, cause of chronic cough in children. More often, the reflux is the result of the cough rather than the cause. The most sensitive tool for assessing GERD is esophageal 24-hour pH/impedance reflux monitoring. However, treatment of the reflux for cough is not recommended unless the patient has clinical features of GERD, including dystonic neck posturing in infants, heartburn, regurgitation, or other symptoms. If the patient has clinical symptoms, then treatment is acid suppressive therapy for 4-8 weeks, followed by a clinical reassessment.
An uncommon cause of chronic cough with no biological mechanism is habit cough. Habit cough is most easily distinguished from other coughs by its sounds, a “large, loud, honking noise,” Bhatia said. It also lacks a clear trigger and is usually absent during sleep, but it can be continuous during the day. Frustratingly, the patients themselves often don’t seem bothered by the cough, but “it’s very disruptive in the school and everywhere else,” Bhatia said. Families and/providers will often have tried multiple treatments and seen no improvement with habit cough.
The first thing to do with habit cough is reassure the family that there’s nothing serious going on because they are often worried by this point. Several non-pharmaceutical treatments can be effective, such as suggestion therapy or the “warm water technique,” in which the patient takes a sip of warm water every time they feel the urge to cough. “If they’re able to break the cycle, most of the time, they are fine,” Bhatia said. In rarer cases, more involved behavioral interventions may be indicated, such as a psychology referral if an underlying anxiety or other behavioral disorder is contributing.
Newer Causes of Cough
Two more recent causes of cough to watch for are long COVID and e-cigarette or vaping product–associated lung injury (EVALI), Bhatia said. The clearest sign of EVALI is a history of e-cigarette/vaping exposure, but clinical symptoms include a dry cough that occurs with dyspnea and chest pain. A chest x-ray may show diffuse, hazy, or consolidative opacities. Sometimes antibiotics or steroids can be helpful, but the evidence isn’t strong, and the most effective treatment is stopping e-cigarette use. Less commonly, passive exposure to vaping can also be associated with EVALI.
The most recent research on long COVID suggests that about 10-20% of children with acute COVID develop long COVID, and about a quarter of these patients develop a chronic dry cough. It’s often associated with fatigue and shortness of breath, which can be assessed with cardiopulmonary exercise testing. Sometimes a short trial of inhaled steroids can help.
Bhatia also mentioned a handful of other uncommon causes of chronic cough that most American pediatricians are unlikely to see: Childhood interstitial lung disease, tuberculosis, use of Angiotensin-Converting Enzyme inhibitors, and a build-up of ear wax via the Arnold’s nerve reflex.
Evaluation and Workup
Bhatia also discussed what to cover while taking a history and questions to ask. The history should include the type of cough, the onset timing (sudden vs gradual), associated symptoms, the cough trajectory, medications the patient is taking, and the patient’s past medical history and environmental exposures. Those attributes are included in this more comprehensive list of questions to consider during evaluation, adapted from a list provided in a 2019 article in Paediatric Respiratory Reviews:
- Age of onset and duration?
- Was the onset sudden or associate with an illness?
- Is the cough wet or dry?
- What does the cough sound like?
- How often does the cough occur?
- Is it progressive?
- Is it present during sleep?
- Are there any other associated symptoms, such as wheeze, dyspnea, vomiting, chest pain, etc?
- Are there any exacerbating factors or known triggers?
- Are there any relieving factors, including a trial of bronchodilators?
- Has there been exposure to auto-irritants, such as secondhand smoke?
- What is the cough’s effect on the child and on others around the child?
- Does the child have any other underlying conditions such as neuromuscular disease or asthma?
- What medications is the child taking or has recently taken?
- Is there a family history of atopy and/or respiratory disease?
Bhatia also recommended paying special attention to the following red flags or key features that may help more quickly narrow the diagnosis and often require a specialist referral:
- Digital clubbing, failure to thrive, or low tone
- An abnormal cardiac exam
- Tachypnea, hypoxemia, chest retractions, or hemoptysis
- Abnormal breath sounds such as unilateral wheezing or coarse crackles
- Abnormal spirometry in those aged 5 and older showing reversible obstruction, which often indicates asthma
- An abnormal chest x-ray with, for example, bilateral infiltrates, hyperinflation, right middle lobe syndrome, situs inversus, unilateral hyperlucency, a right aortic arch, etc.
No external funding was used for the presentation. Bhatia and Quijada had no disclosures.

Over 3 Years, Atopic Dermatitis Well-Controlled with Lebrikizumab
AMSTERDAM — among those followed up for an additional 2 years, according to the latest data from an extension study.
At the end of the maintenance phase of the pivotal trials at 12 months, 84% of the patients enrolled into the extension had clear or almost clear skin, as per the Investigator Global Assessment (IGA). This overall figure as well as the proportion with even better responses have persisted unchanged, reported Diamant Thaçi, MD, PhD, professor and head of the Comprehensive Center for Inflammatory Medicine, University of Lübeck in Germany.
Responses at 3 Years Maintained
“This is really quite remarkable,” Dr. Thaçi said. “Roughly all the patients maintained their response.” These results became even more remarkable when patients were assessed for their use of adjunctive therapy to control flares.
“Over the whole follow-up, 90% had no need for topical corticosteroids or any other rescue therapy,” Dr. Thaçi reported, providing data from the ADjoin lebrikizumab extension study during a late-breaking news session at the annual meeting of the European Academy of Dermatology and Venereology.
The patients in ADjoin were enrolled from the pivotal phase 3 ADvocate 1 and 2 trials completed almost 2 years ago and published together in March 2023. Lebrikizumab was approved in the United States in September 2024 for moderate to severe AD in patients aged ≥ 12 years, following previous approvals in Europe in 2023 and in Japan in January 2024.
In these two identical trials with a total of 564 patients, the primary endpoint was an IGA of 0 or 1, signifying clear or almost clear skin. At nearly 40%, the proportion of patients reaching this outcome at 16 weeks was about threefold greater (P < .001) on lebrikizumab than on placebo. The benefit was similar on secondary endpoints, such as 75% improvement in the Eczema Area and Severity Index (EASI75) score.
At the end of the double-blind, placebo-controlled 16-week phase of the ADvocate 1 and 2 trials, which enrolled adults and adolescents aged ≥ 12 years, responders were enrolled into a maintenance phase in which they were rerandomized to 250 mg lebrikizumab every 2 weeks (Q2W) or every 4 weeks (Q4W). The latter is the approved maintenance dose.
At the end of the maintenance phase, which lasted another 32 weeks (total exposure of 52 weeks for those initially randomized to lebrikizumab), patients were invited into the ADjoin extension. The only exclusions from the extension were serious adverse events related to lebrikizumab and noncompliance.
Response Curves Appear as Straight Lines
Over the next 2 years of ADjoin, response curves appeared as straight lines not only for the overall response but when patients were stratified for different levels of response at the extension study entry. Specifically, 81.5% and 83.3% had an IGA score of 0 or 1 in the Q2W and Q4W arms at completion of the ADvocate 16-week double-blind phase. At 3 years, the rates were 84.0% and 82.9%, respectively.
For the subgroup who entered ADjoin with an EASI75 or an EASI90 response, the persistence of this level of response over 2 years was similar, although there was some gain observed among those who entered the trial with an EASI75 response.
“Not only did these patients maintain their response, but the response on average slowly improved, so that there were more patients with an EASI90 response at the 3-year timepoint,” Dr. Thaçi said.
Of the 181 patients in the ADjoin extension, 82 patients were maintained on Q2W dosing and 99 were maintained on Q4W lebrikizumab. Their mean age was about 35 years, more than half were women, and nearly 40% had severe AD at the time they enrolled in the ADvocate trials. There was essentially no difference in response rates among those in the Q2W and Q4W arms over time in ADjoin.
Side Effect Profile Essentially Unchanged
The side effect and tolerability profiles, which were favorable in the original 16-week placebo-controlled study, have remained unchanged over the subsequent maintenance phase and through the additional 2 years of the ADjoin extension.
“There continued to be reports of conjunctivitis, which is very specific for anti–IL-13 therapies,” Dr. Thaçi said. However, he said that the incidence did not increase over time, and because it was easy to treat, “most patients do not discontinue lebrikizumab for this reason.” Moreover, he said the impression was that “the number of patients experiencing adverse effects has been decreasing over time.”
Calling these long-term results “very exciting,” Dr. Thaçi called lebrikizumab “a very valuable option for long-term AD care.”
Asked for his perspective on the results, Jonathan I. Silverberg, MD, PhD, Director of Clinical Research, Department of Dermatology, George Washington University, Washington, DC, said that it is important to study long-term efficacy, and these results are positive. Without direct comparisons to other biologics available for AD, nothing can be implied about the relative efficacy of monoclonal antibodies approved for AD.
“These data are important both from an efficacy and safety perspective” for those advising patients who need chronic AD treatment, said Dr. Silverberg, who was the principal investigator of the ADvocate trials.
Earlier this year, 5-year follow-up data were published for dupilumab. Of 326 patients who remained on therapy this long, 220 (67%) maintained an IGA of 0 or 1 at the end of the study. There were no unexpected adverse events, which were generally stable or declined throughout the study.
Dr. Thaçi has financial relationships with AbbVie, Amgen, Boehringer Ingelheim, Bristol-Myers Squibb, Celltrion, Galderma, Leo Pharma, L’Oreal, Janssen-Cilag, New Bridge, Novartis, Pfizer, Regeneron, Roche, Sanofi, Sun Pharma, UCB, and Vichy. Dr. Silverberg reported financial relationships with more than 40 pharmaceutical companies including those that make drugs for AD.

FROM EADV 2024
State of Confusion: Should All Children Get Lipid Labs for High Cholesterol?
Clinicians receive conflicting advice on whether to order blood tests to screen for lipids in children. A new study could add to the confusion. Researchers found that a combination of physical proxy measures such as hypertension and body mass index (BMI) predicted the risk for future cardiovascular events as well as the physical model plus lipid labs, questioning the value of those blood tests.
Some medical organizations advise screening only for high-risk children because more research is needed to define the harms and benefits of universal screening. Diet and behavioral changes are sufficient for most children, and universal screening could lead to false positives and unnecessary further testing, they said.
Groups that favor lipid tests for all children say these measurements detect familial hypercholesterolemia (FH) that would not otherwise be diagnosed, leading to treatment with drugs like statins and a greater chance of preventing cardiovascular disease (CVD) in adulthood.
Researchers from the new study said their findings do not address screenings for FH, which affects 1 in 250 US children and puts them at a risk for atherosclerotic CVD.
Recommending Blood Tests in Age Groups
One of the seminal guidelines on screening lipids in children came from the National Heart, Lung, and Blood Institute (NHLBI), which in 2011 recommended children undergo dyslipidemia screening between the ages of 9 and 11 years and again between 17 and 21 years. Children should receive a screening starting at age 2 years if they have a family history of CVD or dyslipidemia or have diabetes, an elevated BMI, or hypertension. The American Academy of Pediatrics shortly followed suit, issuing similar recommendations.
Screening for the two subsets of ages was an expansion from the original 1992 guidelines from the National Cholesterol Education Program, which recommended screening only for children with either a family history of early CVD or elevated total cholesterol levels.
A 2011 panel for the NHLBI said the older approach identified significantly fewer children with abnormal levels of low-density lipoprotein cholesterol (LDL-C) than the addition of two age groups for screening, adding that many children do not have a complete family history. The American College of Cardiology and American Heart Association later supported NHLBI’s stance in their joint guidelines on the management of cholesterol.
Mark Corkins, MD, chair of the AAP’s Committee on Nutrition, told Medscape Medical News that if children are screened only because they have obesity or a family history of FH, some with elevated lipid levels will be missed. For instance, studies indicate caregiver recall of FH often is inaccurate, and the genetic disorder that causes the condition is not related to obesity.
“The screening is to find familial hypercholesterolemia, to try to find the ones that need therapy,” that would not be caught by the risk-based screening earlier on in childhood, Corkins said.
Only Screen Children With Risk Factors
But other groups do not agree. The US Preventive Services Task Force (USPSTF) found insufficient evidence to recommend for or against screening for lipid disorders in asymptomatic children and teens.
The group also said it found inadequate evidence that lipid-lowering interventions in the general pediatric population lead to reductions in cardiovascular events or all-cause mortality once they reached adulthood. USPSTF also raised questions about the safety of lipid-lowering drugs in children.
“The current evidence is insufficient to assess the balance of benefits and harms of screening for lipid disorders in children and adolescents 20 years or younger,” the panel wrote.
The American Academy of Family Physicians supports USPSTF’s recommendations.
Low Rate of Screening
While the uncertainty over screening in children continues, the practice has been adopted by a minority of clinicians.
A study published in JAMA Network Open in July found 9% of 700,000 9- to 11-year-olds had a documented result from a lipid screening. Among more than 1.3 million 17- to 21-year-olds, 13% had received a screening.
As BMI went up, so did screening rates. A little over 9% children and teens with a healthy weight were screened compared with 14.7% of those with moderate obesity and 21.9% of those with severe obesity.
Among those screened, 32.3% of 9- to 11-year-olds and 30.2% of 17- to 21-year-olds had abnormal lipid levels, defined as having one elevated measure out of five, including total cholesterol of 200 mg/dL or higher or LDL-C levels of 130 mg/dL or higher.
Justin Zachariah, MD, MPH, an associate professor of pediatrics-cardiology at Baylor College of Medicine in Houston, spoke about physicians screening children based only on factors like obesity during a presentation at the recent annual meeting of the American Academy of Pediatrics. He cited research showing roughly one in four children with abnormal lipids had a normal weight.
If a clinician is reserving a lipid screening for a child who is overweight or has obesity, “you’re missing nearly half the problem,” Zachariah said during his presentation.
One reason for the low rate of universal screening may be inattention to FH by clinicians, according to Samuel S. Gidding, MD, a professor in the Department of Genomic Health at Geisinger College of Health Sciences in Bridgewater Corners, Vermont.
For instance, a clinician has only a set amount of time during a well-child visit and other issues may take precedence, “so it doesn’t make sense to broach preventive screening for something that could happen 30 or 40 years from now, vs this [other] very immediate problem,” he said.
Clinicians “are triggered to act on the LDL level, but don’t think about FH as a possible diagnosis,” Gidding told Medscape Medical News.
Another barrier is that in some settings, caregivers must take children and teens to another facility on a different day to fulfill an order for a lipid test.
“It’s reluctance of doctors to order it, knowing patients won’t go through with it,” Gidding said.
Gidding is a consultant for Esperion Therapeutics. Other sources in this story reported no relevant financial conflicts of interest.

Diet and behavioral changes are sufficient for most children, and universal screening could lead to false positives and unnecessary further testing, they said.
Groups that favor lipid tests for all children say these measurements detect familial hypercholesterolemia (FH) that would not otherwise be diagnosed, leading to treatment with drugs like statins and a greater chance of preventing cardiovascular disease (CVD) in adulthood.
Researchers from the new study said their findings do not address screenings for FH, which affects 1 in 250 US children and puts them at a risk for atherosclerotic CVD.
Recommending Blood Tests in Age Groups
One of the seminal guidelines on screening lipids in children came from the National Heart, Lung, and Blood Institute (NHLBI), which in 2011 recommended children undergo dyslipidemia screening between the ages of 9 and 11 years and again between 17 and 21 years. Children should receive a screening starting at age 2 years if they have a family history of CVD or dyslipidemia or have diabetes, an elevated BMI, or hypertension. The American Academy of Pediatrics shortly followed suit, issuing similar recommendations.
Screening for the two subsets of ages was an expansion from the original 1992 guidelines from the National Cholesterol Education Program, which recommended screening only for children with either a family history of early CVD or elevated total cholesterol levels.
A 2011 panel for the NHLBI said the older approach identified significantly fewer children with abnormal levels of low-density lipoprotein cholesterol (LDL-C) than the addition of two age groups for screening, adding that many children do not have a complete family history. The American College of Cardiology and American Heart Association later supported NHLBI’s stance in their joint guidelines on the management of cholesterol.
Mark Corkins, MD, chair of the AAP’s Committee on Nutrition, told Medscape Medical News that if children are screened only because they have obesity or a family history of FH, some with elevated lipid levels will be missed. For instance, studies indicate caregiver recall of FH often is inaccurate, and the genetic disorder that causes the condition is not related to obesity.
“The screening is to find familial hypercholesterolemia, to try to find the ones that need therapy,” that would not be caught by the risk-based screening earlier on in childhood, Corkins said.
Only Screen Children With Risk Factors
But other groups do not agree. The US Preventive Services Task Force (USPSTF) found insufficient evidence to recommend for or against screening for lipid disorders in asymptomatic children and teens.
The group also said it found inadequate evidence that lipid-lowering interventions in the general pediatric population lead to reductions in cardiovascular events or all-cause mortality once they reached adulthood. USPSTF also raised questions about the safety of lipid-lowering drugs in children.
“The current evidence is insufficient to assess the balance of benefits and harms of screening for lipid disorders in children and adolescents 20 years or younger,” the panel wrote.
The American Academy of Family Physicians supports USPSTF’s recommendations.
Low Rate of Screening
While the uncertainty over screening in children continues, the practice has been adopted by a minority of clinicians.
A study published in JAMA Network Open in July found 9% of 700,000 9- to 11-year-olds had a documented result from a lipid screening. Among more than 1.3 million 17- to 21-year-olds, 13% had received a screening.
As BMI went up, so did screening rates. A little over 9% children and teens with a healthy weight were screened compared with 14.7% of those with moderate obesity and 21.9% of those with severe obesity.
Among those screened, 32.3% of 9- to 11-year-olds and 30.2% of 17- to 21-year-olds had abnormal lipid levels, defined as having one elevated measure out of five, including total cholesterol of 200 mg/dL or higher or LDL-C levels of 130 mg/dL or higher.
Justin Zachariah, MD, MPH, an associate professor of pediatrics-cardiology at Baylor College of Medicine in Houston, spoke about physicians screening children based only on factors like obesity during a presentation at the recent annual meeting of the American Academy of Pediatrics. He cited research showing roughly one in four children with abnormal lipids had a normal weight.
If a clinician is reserving a lipid screening for a child who is overweight or has obesity, “you’re missing nearly half the problem,” Zachariah said during his presentation.
One reason for the low rate of universal screening may be inattention to FH by clinicians, according to Samuel S. Gidding, MD, a professor in the Department of Genomic Health at Geisinger College of Health Sciences in Bridgewater Corners, Vermont.
For instance, a clinician has only a set amount of time during a well-child visit and other issues may take precedence, “so it doesn’t make sense to broach preventive screening for something that could happen 30 or 40 years from now, vs this [other] very immediate problem,” he said.
Clinicians “are triggered to act on the LDL level, but don’t think about FH as a possible diagnosis,” Gidding told Medscape Medical News.
Another barrier is that in some settings, caregivers must take children and teens to another facility on a different day to fulfill an order for a lipid test.
“It’s reluctance of doctors to order it, knowing patients won’t go through with it,” Gidding said.

Type 2 Diabetes More Prevalent Than Type 1 Among Adolescents in Some Areas
“This is an emerging epidemic,” said Orit Pinhas-Hamiel, MD, director of the Pediatric Endocrinology and Diabetes Unit at Sheba Medical Center in Ramat Gan, Israel, at the annual meeting of the European Association for the Study of Diabetes, noting that these young patients, most with obesity, exhibit a significantly higher incidence of complications than adults with type 2 diabetes or young people with type 1 diabetes.
In 2017-2018, the incidence of type 2 diabetes among patients aged 15-19 years (19.7 per 100,000) surpassed that of type 1 diabetes (14.6 per 100,000), according to data from the United States.
“This is the first time that the incidence of type 2 diabetes has exceeded that of type 1 among youth,” said Pinhas-Hamiel. A review of 2021 published a few months ago highlighted this surge, with countries like China, India, the United States, Brazil, and Mexico leading the way.
SEARCH and TODAY
The SEARCH for Diabetes in Youth study, which was launched in 2000, is a multicenter observational study in the United States aimed at estimating the prevalence, incidence, and complications of types 1 and 2 diabetes among young patients. The Treatment Options for Type 2 Diabetes in Adolescents and Youth (TODAY) study is an interventional study focusing on adolescents with type 2 diabetes to evaluate the effectiveness of various treatment options.
“Diabesity” — the dual global epidemic of obesity and type 2 diabetes — has visible consequences from the moment of diagnosis, including hypertension. In the TODAY study, 11.6% adolescents had hypertension at diagnosis. A study conducted in Hong Kong involving 391 children younger than 18 years revealed that 22.5% had hypertension. In SEARCH, 27% young patients diagnosed with type 2 diabetes for 1.5 years had hypertension.
In addition, the SEARCH study found that 27% young individuals had low levels of high-density lipoprotein cholesterol, while 25% had high triglyceride levels, at 1.5 years after diagnosis.
Overall, the cumulative incidence of long-term diabetic complications was assessed in 500 adolescents participating in TODAY (mean age, 26.4 ± 2.8 years; mean time since diagnosis, 13.3 ± 1.8 years). The initial prevalence was 19.2%, while the cumulative incidence rose to 67.5% after 15 years of follow-up.
For dyslipidemia, the initial prevalence was 20.8%, with a cumulative incidence of 51.6%. The incidence of diabetic nephropathy was 54.8% and neuropathies was 32.4%. The prevalence of retinopathy was 13.7% for the period 2010-2011 and 51% for 2017-2018.
At least one complication was observed in 60.1% participants and at least two in 28.4%. As expected, risk factors for developing complications included belonging to a racial or ethnic minority, hyperglycemia, hypertension, and dyslipidemia.
“Among those who developed type 2 diabetes in adolescence, the risk for complications, including microvascular complications, has continuously increased and affected most participants in young adulthood,” said Pinhas-Hamiel.
At the same time, the rate of treatment with lipid-lowering and antihypertensive medications remains low among young people with type 2 diabetes. The management of dyslipidemia is suboptimal, with only 5% young patients with diabetes and dyslipidemia receiving appropriate medications. Furthermore, treatment adherence is lacking. In the TODAY cohort, for example, only one third of participants with high levels of low-density lipoprotein cholesterol were on lipid-lowering medications, and only half of the young patients with hypertension were taking antihypertensives.
Focus on Diabetic Nephropathy
Diabetic kidney disease is the leading microvascular complication of type 2 diabetes in adolescents. It is associated with rapid progression and poor prognosis. The natural history begins with hyperfiltration: A consequence of obesity and impaired glucose tolerance. Structural renal changes can be detected as early as 1.5 years after diagnosis.
The second stage is characterized by a reduction in the glomerular filtration rate. At this stage, “the structural changes in the kidney are typical but often present,” said Pinhas-Hamiel, making this period critical for reducing risk factors.
In TODAY, the cumulative incidence of diabetic nephropathy was 54.8%. The prevalence at inclusion was 8%. In SEARCH, after 8 years, the prevalence of diabetic kidney disease was 19.9% among adolescents with type 2 diabetes vs 5.8% among those with type 1 diabetes. A pre-analysis revealed that the overall prevalence of macroalbuminuria among 730 children and adolescents with type 2 diabetes was 3.8%. The ages at diagnosis of type 2 diabetes ranged from 6.5 to 21 years, and the duration of the disease varied from diagnosis to 15 years after.
Diabetic retinopathy was present in 50% participants in the TODAY study at age 25 years (ie, after 12 years of disease). In SEARCH, 56% young patients had diabetic retinopathy after 12.5 years of diabetes. In addition, in the same study, the prevalence of peripheral neuropathy, assessed after 8 years, was 22% among adolescents with type 2 diabetes vs 7% among those with type 1 diabetes.
Cardiovascular Autonomic Neuropathy
A decrease in heart rate variability was observed in 47% young patients with type 2 diabetes after an average disease duration of only 1.7 years. In SEARCH, the prevalence of cardiovascular autonomic neuropathy, assessed after 8 years of disease, was 17% in adolescents with type 2 diabetes versus 12% in those with type 1 diabetes.
Overall, 7.1% participants had three complications: nephropathy, retinopathy, and neuropathy. The cumulative incidence of microvascular complications was 80%.
Moreover, A1c levels deteriorated progressively throughout the follow-up period. Approximately 45% participants had an A1c of at least 10%, and 20% were between 8% and 10%. Body mass index consistently remained between 35 and 37.5.
Young patients with type 2 diabetes exhibit endothelial dysfunction, increased carotid intima-media thickness, elevated arterial stiffness, left ventricular hypertrophy, diastolic dysfunction, and reduced maximal exercise capacity. All these factors predict cardiovascular morbidity and mortality.
In TODAY, 17 serious cardiovascular events were recorded, including four myocardial infarctions, six cases of congestive heart failure, three coronary events, and four strokes.
In an analysis of the TODAY and SEARCH studies, although the average duration of diabetes was similar, complications were more frequent among young patients with type 2 diabetes than among those with type 1 diabetes. Microvascular complications were 2.5 times more frequent, and macrovascular complications were four times more frequent.
In SEARCH, excessive mortality was observed among young adults for each type of diabetes. Differences in risk were associated with diabetes type, age, race/ethnicity, and sex. Mortality ratios were 1.5 and 2.3 for types 1 and 2 diabetes, respectively.
Women had higher mortality rates than men. Diabetes was the underlying cause of death in 9.1% cases, which was comparable to cardiovascular diseases or cancer (10.9%). According to a life expectancy model, young patients with type 2 diabetes lose about 15 years of life.
Eating Disorders and Depression
Beyond these complications, other issues are often present among adolescents with type 2 diabetes. Approximately 50% have eating disorders (compared with 21% among those with type 1 diabetes), 19.3% report depressive symptoms, and 18.9% have expressed thoughts of self-harm. In addition, 19.6% have polycystic ovary syndrome. Z-scores for bone mineral density at the femoral neck and lumbar spine were significantly lower in adolescents with type 2 diabetes than in healthy peers. The presence of metabolic dysfunction–associated fatty liver disease is also more pronounced.
“The recent approvals of new pharmacological interventions for weight loss and improved glycemic control in adolescents offer hope. We hope that, over the next decade, the prevalence of complications among these young patients with type 2 diabetes will decline. In the meantime, a proactive approach is essential to prevent complications related to type 2 diabetes in these youth,” Pinhas-Hamiel concluded.

Young patients with type 2 diabetes exhibit endothelial dysfunction, increased carotid intima-media thickness, elevated arterial stiffness, left ventricular hypertrophy, diastolic dysfunction, and reduced maximal exercise capacity. All these factors predict cardiovascular morbidity and mortality.
In TODAY, 17 serious cardiovascular events were recorded, including four myocardial infarctions, six cases of congestive heart failure, three coronary events, and four strokes.
In an analysis of the TODAY and SEARCH studies, although the average duration of diabetes was similar, complications were more frequent among young patients with type 2 diabetes than among those with type 1 diabetes. Microvascular complications were 2.5 times more frequent, and macrovascular complications were four times more frequent.
In SEARCH, excessive mortality was observed among young adults for each type of diabetes. Differences in risk were associated with diabetes type, age, race/ethnicity, and sex. Mortality ratios were 1.5 and 2.3 for types 1 and 2 diabetes, respectively.
Women had higher mortality rates than men. Diabetes was the underlying cause of death in 9.1% cases, which was comparable to cardiovascular diseases or cancer (10.9%). According to a life expectancy model, young patients with type 2 diabetes lose about 15 years of life.
Eating Disorders and Depression
Beyond these complications, other issues are often present among adolescents with type 2 diabetes. Approximately 50% have eating disorders (compared with 21% among those with type 1 diabetes), 19.3% report depressive symptoms, and 18.9% have expressed thoughts of self-harm. In addition, 19.6% have polycystic ovary syndrome. Z-scores for bone mineral density at the femoral neck and lumbar spine were significantly lower in adolescents with type 2 diabetes than in healthy peers. The presence of metabolic dysfunction–associated fatty liver disease is also more pronounced.
“The recent approvals of new pharmacological interventions for weight loss and improved glycemic control in adolescents offer hope. We hope that, over the next decade, the prevalence of complications among these young patients with type 2 diabetes will decline. In the meantime, a proactive approach is essential to prevent complications related to type 2 diabetes in these youth,” Pinhas-Hamiel concluded.

Overuse of Digital Devices in the Exam Room: A Teaching Opportunity
A 3-year-old presents to my clinic for evaluation of a possible autism spectrum disorder/difference. He has a history of severe emotional dysregulation, as well as reduced social skills and multiple sensory sensitivities. When I enter the exam room he is watching videos on his mom’s phone, and has some difficulty transitioning to play with toys when I encourage him to do so. He is eventually able to cooperate with my testing, though a bit reluctantly, and scores within the low average range for both language and pre-academic skills. His neurologic exam is within normal limits. He utilizes reasonably well-modulated eye contact paired with some typical use of gestures, and his affect is moderately directed and reactive. He displays typical intonation and prosody of speech, though engages in less spontaneous, imaginative, and reciprocal play than would be expected for his age. His mother reports decreased pretend play at home, minimal interest in toys, and difficulty playing cooperatively with other children.
Upon further history, it becomes apparent that the child spends a majority of his time on electronic devices, and has done so since early toddlerhood. Further dialogue suggests that the family became isolated during the COVID-19 pandemic, and has not yet re-engaged with the community in a meaningful way. The child has had rare opportunity for social interactions with other children, and minimal access to outdoor play. His most severe meltdowns generally involve transitions away from screens, and his overwhelmed parents often resort to use of additional screens to calm him once he is dysregulated.
At the end of the visit, through shared decision making, we agree that enrolling the child in a high-quality public preschool will help parents make a concerted effort towards a significant reduction in the hours per day in which the child utilizes electronic devices, while also providing him more exposure to peers. We plan for the child to return in 6 months for a re-evaluation around social-emotional skills, given his current limited exposure to peers and limited “unplugged” play-time.
Overutilization of Electronic Devices
As clinicians, we can all see how pervasive the use of electronic devices has become in the lives of the families we care for, as well as in our own lives, and how challenging some aspects of modern parenting have become. The developmental impact of early and excessive use of screens in young children is well documented,1 but as clinicians it can be tricky to help empower parents to find ways to limit screen time. When parents use screens to comfort and amuse their children during a clinic visit, this situation may serve as an excellent opportunity for a meaningful and respectful conversation around skill deficits which can result from overutilization of electronic devices in young children.
One scenario I often encounter during my patient evaluations as a developmental and behavioral pediatrician is children begging their parents for use of their phone throughout their visits with me. Not infrequently, a child is already on a screen when I enter the exam room, even when there has been a minimal wait time, which often leads to some resistance on behalf of the child as I explain to the family that a significant portion of the visit involves my interactions with the child, testing the child, and observing their child at play. I always provide ample amounts of age-appropriate art supplies, puzzles, fidgets, building toys, and imaginative play items to children during their 30 to 90 minute evaluations, but these are often not appealing to children when they have been very recently engaged with an electronic device. At times I also need to ask caretakers themselves to please disengage from their own electronic devices during the visit so that I can involve them in a detailed discussion about their child.
One challenge with the practice of allowing children access to entertainment on their parent’s smartphones in particular, lies in the fact that these devices are almost always present, meaning there is no natural boundary to inhibit access, in contrast to a television set or stationary computer parked in the family living room. Not dissimilar to candy visible in a parent’s purse, a cell phone becomes a constant temptation for children accustomed to utilizing them at home and public venues, and the incessant begging can wear down already stressed parents.
Children can become conditioned to utilize the distraction of screens to avoid feelings of discomfort or stress, and so can be very persistent and emotional when asking for the use of screens in public settings. Out in the community, I very frequently see young children and toddlers quietly staring at their phones and tablets while at restaurants and stores. While I have empathy for exhausted parents desperate for a moment of quiet, if this type of screen use is the rule rather than the exception for a child, there is risk for missed opportunities for the development of self-regulation skills.
Additionally, I have seen very young children present to my clinic with poor posture and neck pain secondary to chronic smartphone use, and young children who are getting minimal exercise or outdoor time due to excessive screen use, leading to concerns around fine and gross motor skills as well.
While allowing a child to stay occupied with or be soothed by a highly interesting digital experience can create a more calm environment for all, if habitual, this use can come at a cost regarding opportunities for the growth of executive functioning skills, general coping skills, general situational awareness, and experiential learning. Reliance on screens to decrease uncomfortable experiences decreases the opportunity for building distress tolerance, patience, and coping skills.
Of course there are times of extreme distress where a lollipop or bit of screen time might be reasonable to help keep a child safe or further avoid emotional trauma, but in general, other methods of soothing can very often be utilized, and in the long run would serve to increase the child’s general adaptive functioning.
A Teachable Moment
When clinicians encounter screens being used by parents to entertain their kids in clinic, it provides a valuable teaching moment around the risks of using screens to keep kids regulated and occupied during life’s less interesting or more anxiety provoking experiences. Having a meaningful conversation about the use of electronic devices with caregivers by clinicians in the exam room can be a delicate dance between providing supportive education while avoiding judgmental tones or verbiage. Normalizing and sympathizing with the difficulty of managing challenging behaviors from children in public spaces can help parents feel less desperate to keep their child quiet at all costs, and thus allow for greater development of coping skills.
Some parents may benefit from learning simple ideas for keeping a child regulated and occupied during times of waiting such as silly songs and dances, verbal games like “I spy,” and clapping routines. For a child with additional sensory or developmental needs, a referral to an occupational therapist to work on emotional regulation by way of specific sensory tools can be helpful. Parent-Child Interaction Therapy for kids ages 2 to 7 can also help build some relational activities and skills that can be utilized during trying situations to help keep a child settled and occupied.
If a child has qualified for Developmental Disability Services (DDS), medical providers can also write “prescriptions’ for sensory calming items which are often covered financially by DDS, such as chewies, weighted vests, stuffed animals, and fidgets. Encouraging parents to schedule allowed screen time at home in a very predictable and controlled manner is one method to help limit excessive use, as well as it’s utilization as an emotional regulation tool.
For public outings with children with special needs, and in particular in situations where meltdowns are likely to occur, some families find it helpful to dress their children in clothing or accessories that increase community awareness about their child’s condition (such as an autism awareness t-shirt). This effort can also help deflect unhelpful attention or advice from the public. Some parents choose to carry small cards explaining the child’s developmental differences, which can then be easily handed to unsupportive strangers in community settings during trying moments.
Clinicians can work to utilize even quick visits with families as an opportunity to review the American Academy of Pediatrics screen time recommendations with families, and also direct them to the Family Media Plan creation resources. Parenting in the modern era presents many challenges regarding choices around the use of electronic devices with children, and using the exam room experience as a teaching opportunity may be a helpful way to decrease utilization of screens as emotional regulation tools for children, while also providing general education around healthy use of screens.
