It might be possible to develop a simple test to identify newborn children who are at risk of later developing atopic dermatitis (AD), according to findings from a Danish prospective birth cohort study.

In the study, the Barrier Dysfunction in Atopic Newborns Study (BABY), several biomarkers were found in the skin cells of newborns that were predictive not only for having AD but also for having more severe disease.

“We are able to identify predictive immune biomarkers of atopic dermatitis using a noninvasive method that was not associated with any pain,” one of the study’s investigators, Anne-Sofie Halling, MD, said at a press briefing at the annual congress of the European Academy of Dermatology and Venereology.

“Importantly, we were able to predict atopic dermatitis occurring months after [sample] collection,” said Dr. Halling, who works at Bispebjerg Hospital and is a PhD student at the University of Copenhagen.

These findings could hopefully be used to help identify children “so that preventive strategies can target these children ... and decrease the incidence of this common disease,” she added.

AD is caused “by a complex interplay between skin barrier dysfunction and immune dysregulation,” Dr. Halling said, and it is “the first step in the so-called atopic march, where children also develop food allergy, asthma, and rhinitis.” Almost all cases of AD begin during the first years of life. Approximately 15%-20% of children can be affected, she noted, emphasizing the high burden of the disease and pointing out that strategies are shifting toward trying to prevent the disease in those at risk.

Copenhagen BABY cohort

This is where the BABY study comes in, Dr. Halling said. The study enrolled 450 children at birth and followed them until age 2 years. Gene mutation testing was performed at enrollment. All children underwent skin examination, and skin samples were taken using tape strips. Tape strips were applied to the back of the hand of children born at term and between the shoulder blades on the back of children who were premature.

Skin examinations were repeated, and skin samples were obtained again at age 2 months. They were taken again only if there were any signs of AD. For those diagnosed with AD, disease severity was assessed using the Eczema Area and Severity Index (EASI) by the treating physician. Children were excluded if they had AD at the time the tape strip testing was due to be performed.
 

Comparing term and preterm children

Dr. Halling noted that analyses were performed separately for the 300 children born at term and for the 150 who were preterm.

The prevalence of AD was higher among children born at term than among the preterm children (34.6% vs. 21.2%), and the median time to onset was shorter (6 months vs. 8 months). There were also differences in the EASI scores among those who developed AD; median scores were higher in the children born at term than in the preterm children (4.1 vs. 1.6).

More children born at term than preterm children had moderate to severe AD (23.3% vs. 8%), Dr. Halling reported.
 

TARC, IL-8, and IL-18 predictive of AD

Multiple immune biomarkers were tested, including various cytokines and filaggrin degradation products. On examination of skin samples collected at birth, no particular biomarkers were found at higher levels among children who developed AD in comparison with those who did not develop AD.

With regard to biomarkers examined in skin samples at 2 months of age, however, the results were different, Dr. Halling said. One particular cytokine, thymus and activation-regulated chemokine (TARC), was seen to double the risk of AD in the first 2 years of a child’s life.

This doubled risk was seen not only among the children born at term but also among those born preterm, although the data were only significant with regard to the children born at term.

The unadjusted hazard ratios and adjusted HRs (adjusted for parental atopy and filaggrin gene mutations) in term children were 2.11 (95% confidence interval, 1.36-3.26; P = .0008) and 1.85 (95% CI, 1.18-2.89; P = .007), respectively.

For preterm children, the HRs were 2.23 (95% CI, 0.85-5.86; P = .1) and 2.60 (95% CI, 0.98-6.85; P =.05), respectively.

These findings were in line with findings of other studies, Dr. Halling said. “It is well recognized that TARC is currently the best biomarker in patients with established atopic dermatitis.” Moreover, she reported that TARC was associated with a cumulative increase in the risk for AD and that levels were found to be higher in children in whom onset occurred at a later age than among those diagnosed before 6 months of age.

“This is important, as these findings shows that TARC levels predict atopic dermatitis that occurred many months later,” Dr. Halling said.

And, in term-born children at least, TARC upped the chances that the severity of AD would be greater than had it not been present (adjusted HR, 4.65; 95% CI, 1.91-11.31; P = .0007).

Increased levels of interleukin-8 (IL-8) and IL-18 at 2 months of age were also found to be predictive of having moderate to severe AD. The risk was more than double in comparison with those in whom levels were not increased, again only in term-born children.

‘Stimulating and interesting findings’

These data are “very stimulating and interesting,” Dedee Murrell, MD, professor and head of the department of dermatology at St. George Hospital, University of New South Wales, Sydney, observed at the press briefing.

“You found this significant association mainly in the newborn children born at term, and the association in the preterm babies wasn’t as high. Is that anything to do with how they were taken care of in the hospital?” Dr. Murrell asked.

“That’s a really good question,” Dr. Halling said. “Maybe they need to be exposed for a month or two before we are actually able to identify which children will develop atopic dermatitis.”

The study was funded by the Lundbeck Foundation. Dr. Halling has acted as a consultant for Coloplast and as a speaker for Leo Pharma. Dr. Murrell has disclosed no relevant financial relationships.

STOCKHOLM – It remains inconclusive whether SARS-CoV-2 infection predisposes children and adolescents to a higher risk of type 1 diabetes. Data from two new studies and a recently published research letter add to the growing body of knowledge on the subject, but still can’t draw any definitive conclusions.

The latest results from a Norwegian and a Scottish study both examine incidence of type 1 diabetes in young people with a history of SARS-CoV-2 infection and were reported at the annual meeting of the European Association for the Study of Diabetes.

A 60% increased risk for type 1 diabetes at least 31 days after SARS-CoV-2 infection (adjusted hazard ratio, 1.63) was found in the Norwegian study, while in contrast, the Scottish study only found an increased risk in the first few months of the pandemic, in 2020, but importantly, no association over a much longer time period (March 2020–November 2021).

In a comment on Twitter on the two studies presented at EASD, session moderator Kamlesh Khunti, MD, professor of primary care diabetes and vascular medicine at the University of Leicester, (England), said: “In summary, two studies showing no or weak association of type 1 diabetes with COVID.”

But new data in the research letter published in JAMA Network Open, based on U.S. figures, also found an almost doubling of type 1 diabetes in children in the first few months after COVID-19 infection relative to infection with other respiratory viruses.

Lead author of the Scottish study, Helen Colhoun, PhD, honorary public health consultant at Public Health Scotland, commented: “Data in children are variable year on year, which emphasizes the need to be cautious over taking a tiny snapshot.”

Nevertheless, this is “a hugely important question and we must not drop the ball. [We must] keep looking at it and maintain scientific equipoise. ... [This] reinforces the need to carry on this analysis into the future to obtain an unequivocal picture,” she emphasized.
 

Norwegian study: If there is an association, the risk is small

German Tapia, PhD, from the Norwegian Institute of Public Health, Oslo, presented the results of a study of SARS-CoV-2 infection and subsequent risk of type 1 diabetes in 1.2 million children in Norway.

Of these, 424,354 children had been infected with SARS-CoV-2, and there were 990 incident cases of type 1 diabetes.

“What we do know about COVID-19 in children is that the symptoms are mild and only a small proportion are hospitalized with more serious symptoms. But we do not know the long-term effects of COVID-19 infection because this requires a longer follow-up period,” remarked Dr. Tapia, adding that other viral infections are thought to be linked to the development of type 1 diabetes, in particular, respiratory infections.

The data were sourced from the Norwegian Emergency Preparedness Register for COVID-19, which gathers daily data updates including infections (positive and negative results for free-of-charge testing), diagnoses (primary and secondary care), vaccinations (also free of charge), prescribed medications, and basic demographics.

“We link these data using the personal identification number that every Norwegian citizen has,” explained Dr. Tapia.

He presented results from two cohorts: firstly, results in children only, including those tested for SARS-CoV-2 infection, and secondly, a full national Norwegian population cohort.

Regarding the first cohort, those under 18 years who tested positive for SARS-CoV-2 infection, from March 2020 to March 2022, had a significantly increased risk of type 1 diabetes at least 31 days after infection, with an adjusted hazard ratio of 1.63 (95% confidence interval, 1.08-2.47; P = .02). Adjustments were made for age, sex, non-Nordic country of origin, geographic area, and socioeconomic factors.

For children who developed type 1 diabetes within 30 days of a SARS-CoV-2 infection, the HR was 1.26 (95% CI, 0.72-2.19; P = .42), which did not reach statistical significance.

“The fact that fewer people developed type 1 diabetes within 30 days is not surprising because we know that type 1 diabetes develops over a long period of time,” Dr. Tapia said.

“For this reason, we would not expect to find new cases of those people who develop type 1 diabetes within 30 days of COVID-19 infection,” he explained. In these cases, “it is most likely that they already had [type 1 diabetes], and the infection probably triggered clinical symptoms, so their type 1 diabetes was discovered.”

Turning to the full population cohort and diagnoses of type 1 diabetes over 30 days after SARS-CoV-2 infection, the Norwegian researchers found an association, with an HR of 1.57 (95% CI, 1.06-2.33; P = .03), while diagnosis of type 1 diabetes at 30 days or less generated a hazard ratio of 1.22 (95% CI, 0.72-2.19; P = .42).

“So very similar results were found, and after adjustment for confounders, results were still similar,” reported Dr. Tapia.

He also conducted a similar analysis with vaccination as an exposure but found no association between vaccination against SARS-CoV-2 and diagnosis of type 1 diabetes.

“From these results, we conclude that this suggests an increase in diagnosis of type 1 diabetes after SARS-CoV-2 infection, but it must be noted that the absolute risk of developing type 1 diabetes after infection in children is low, with most children not developing the disease,” he emphasized. “There are nearly half a million children who have been infected with SARS-CoV-2 in Norway, but only a very small proportion develop type 1 diabetes.”
 

Scottish study: No association found over longer term

Dr. Colhoun and colleagues looked at the relationship between incident type 1 diabetes and SARS-CoV-2 infection in children in Scotland using e-health record linkage.

The study involved 1.8 million people under 35 years of age and found very weak, if any, evidence of an association between incident type 1 diabetes and SARS-CoV-2.

Examining data between March 2020 and November 2021, Dr. Colhoun and colleagues identified 365,080 individuals up to age 35 with at least one detected SARS-CoV-2 infection during follow-up and 1,074 who developed type 1 diabetes.

“In children under 16 years, suspected cases of type 1 diabetes are admitted to hospital, and 97% of diagnosis dates are recorded in the Scottish Care Information – Diabetes Collaboration register [SCI-Diabetes] prior to or within 2 days of the first hospital admission for type 1 diabetes,” Dr. Colhoun said, stressing the timeliness of the data.

“We found the incidence of type 1 diabetes diagnosis increased 1.2-fold in those aged 0-14 years, but we did not find any association at an individual level of COVID-19 infection over 30 days prior to a type 1 diabetes diagnosis, in this particular dataset,” she reported. In young people aged 15-34, there was a linear increase in incident type 1 diabetes from 2015 to 2021 with no pandemic increase.

Referring to the 1.2-fold increase soon after the pandemic started, she explained that, in 0- to 14-year-olds, the increase followed a drop in the preceding months prepandemic in 2019. They also found that the seasonal pattern of type 1 diabetes diagnoses remained roughly the same across the pandemic months, with typical peaks in February and September.

In the cohort of under 35s, researchers also found a rate ratio of 2.62 (95% CI, 1.81-3.78) within a 30-day window of SARS-CoV-2 infection, but beyond 30 days, no evidence was seen of an association, with a RR of 0.86 (95% CI, 0.62-1.21; P = .40), she reported.

She explained her reasons for not considering diagnoses within 30 days of COVID-19 as causative. Echoing Dr. Tapia, Dr. Colhoun said the median time from symptom onset to diagnosis of type 1 diabetes is 25 days. “This suggests that 50% have had symptoms for over 25 days at diagnosis.”

She also stressed that when they compared the timing of SARS-CoV-2 testing with diagnosis, they found a much higher rate of COVID-19 testing around diagnosis. “This was not least because everyone admitted to hospital had to have a COVID-19 test.”
 

Latest U.S. data point to a link

Meanwhile, for the new data reported in JAMA Network Open, medical student Ellen K. Kendall of Case Western Reserve University, Cleveland, matched 571,256 pediatric patients: 285,628 with COVID-19 and 285,628 with non–COVID-19 respiratory infections.

By 6 months after COVID-19, 123 patients (0.043%) had received a new diagnosis of type 1 diabetes, but only 72 (0.025%) were diagnosed with type 1 diabetes within 6 months after non–COVID-19 respiratory infection.

At 1, 3, and 6 months after infection, risk of diagnosis of type 1 diabetes was greater among those infected with SARS-CoV-2, compared with those with non–COVID-19 respiratory infection (1 month: HR, 1.96; 3 months: HR, 2.10; and 6 months: HR, 1.83), and in subgroups of patients aged 0-9 years, a group unlikely to develop type 2 diabetes.

“In this study, new type 1 diabetes diagnoses were more likely to occur among pediatric patients with prior COVID-19 than among those with other respiratory infections (or with other encounters with health systems),” noted Ms. Kendall and coauthors. “Respiratory infections have previously been associated with onset of type 1 diabetes, but this risk was even higher among those with COVID-19 in our study, raising concern for long-term, post–COVID-19 autoimmune complications among youths.”

“The increased risk of new-onset type 1 diabetes after COVID-19 adds an important consideration for risk–benefit discussions for prevention and treatment of SARS-CoV-2 infection in pediatric populations,” they concluded.

A study from the Centers for Disease Control and Prevention published in January 2022, also concluded there was a link between COVID-19 and diabetes in children, but not with other acute respiratory infections. Children were 2.5 times more likely to be diagnosed with diabetes following a SARS-CoV-2 infection, it found.

However, the study has been criticized because it pooled all types of diabetes together and did not account for other health conditions, medications that can increase blood glucose levels, race, obesity, and other social determinants of health that might influence a child’s risk of acquiring COVID-19 or diabetes.

“I’ve no doubt that the CDC data were incorrect because the incidence rate for ... diabetes, even in those never exposed to COVID-19 infection, was 10 times the rate ever reported in the U.S.,” Dr. Colhoun said. “There’s no way these data are correct. I believe there was a confusion between incidence and prevalence of diabetes.”

“This paper caused a great deal of panic, especially among those who have a child with type 1diabetes, so we need to be very careful not to cause undue alarm until we have more definitive evidence in this arena,” she stressed.

However, she also acknowledged that the new Norwegian study was well conducted, and she has no methodological concerns about it, so “I think we just have to wait and see.”

Given the inconclusiveness on the issue, there is an ongoing CoviDiab registry collecting data on this very subject.

Dr. Tapia presented on behalf of lead author Dr. Gulseth, who has reported no relevant financial relationships. Dr. Colhoun also reported no relevant financial relationships.

For children who developed type 1 diabetes within 30 days of a SARS-CoV-2 infection, the HR was 1.26 (95% CI, 0.72-2.19; P = .42), which did not reach statistical significance.

“The fact that fewer people developed type 1 diabetes within 30 days is not surprising because we know that type 1 diabetes develops over a long period of time,” Dr. Tapia said.

“For this reason, we would not expect to find new cases of those people who develop type 1 diabetes within 30 days of COVID-19 infection,” he explained. In these cases, “it is most likely that they already had [type 1 diabetes], and the infection probably triggered clinical symptoms, so their type 1 diabetes was discovered.”

Turning to the full population cohort and diagnoses of type 1 diabetes over 30 days after SARS-CoV-2 infection, the Norwegian researchers found an association, with an HR of 1.57 (95% CI, 1.06-2.33; P = .03), while diagnosis of type 1 diabetes at 30 days or less generated a hazard ratio of 1.22 (95% CI, 0.72-2.19; P = .42).

“So very similar results were found, and after adjustment for confounders, results were still similar,” reported Dr. Tapia.

He also conducted a similar analysis with vaccination as an exposure but found no association between vaccination against SARS-CoV-2 and diagnosis of type 1 diabetes.

“From these results, we conclude that this suggests an increase in diagnosis of type 1 diabetes after SARS-CoV-2 infection, but it must be noted that the absolute risk of developing type 1 diabetes after infection in children is low, with most children not developing the disease,” he emphasized. “There are nearly half a million children who have been infected with SARS-CoV-2 in Norway, but only a very small proportion develop type 1 diabetes.”
 

Scottish study: No association found over longer term

Dr. Colhoun and colleagues looked at the relationship between incident type 1 diabetes and SARS-CoV-2 infection in children in Scotland using e-health record linkage.

The study involved 1.8 million people under 35 years of age and found very weak, if any, evidence of an association between incident type 1 diabetes and SARS-CoV-2.

Examining data between March 2020 and November 2021, Dr. Colhoun and colleagues identified 365,080 individuals up to age 35 with at least one detected SARS-CoV-2 infection during follow-up and 1,074 who developed type 1 diabetes.

“In children under 16 years, suspected cases of type 1 diabetes are admitted to hospital, and 97% of diagnosis dates are recorded in the Scottish Care Information – Diabetes Collaboration register [SCI-Diabetes] prior to or within 2 days of the first hospital admission for type 1 diabetes,” Dr. Colhoun said, stressing the timeliness of the data.

“We found the incidence of type 1 diabetes diagnosis increased 1.2-fold in those aged 0-14 years, but we did not find any association at an individual level of COVID-19 infection over 30 days prior to a type 1 diabetes diagnosis, in this particular dataset,” she reported. In young people aged 15-34, there was a linear increase in incident type 1 diabetes from 2015 to 2021 with no pandemic increase.

Referring to the 1.2-fold increase soon after the pandemic started, she explained that, in 0- to 14-year-olds, the increase followed a drop in the preceding months prepandemic in 2019. They also found that the seasonal pattern of type 1 diabetes diagnoses remained roughly the same across the pandemic months, with typical peaks in February and September.

In the cohort of under 35s, researchers also found a rate ratio of 2.62 (95% CI, 1.81-3.78) within a 30-day window of SARS-CoV-2 infection, but beyond 30 days, no evidence was seen of an association, with a RR of 0.86 (95% CI, 0.62-1.21; P = .40), she reported.

She explained her reasons for not considering diagnoses within 30 days of COVID-19 as causative. Echoing Dr. Tapia, Dr. Colhoun said the median time from symptom onset to diagnosis of type 1 diabetes is 25 days. “This suggests that 50% have had symptoms for over 25 days at diagnosis.”

She also stressed that when they compared the timing of SARS-CoV-2 testing with diagnosis, they found a much higher rate of COVID-19 testing around diagnosis. “This was not least because everyone admitted to hospital had to have a COVID-19 test.”

Meanwhile, for the new data reported in JAMA Network Open, medical student Ellen K. Kendall of Case Western Reserve University, Cleveland, matched 571,256 pediatric patients: 285,628 with COVID-19 and 285,628 with non–COVID-19 respiratory infections.

By 6 months after COVID-19, 123 patients (0.043%) had received a new diagnosis of type 1 diabetes, but only 72 (0.025%) were diagnosed with type 1 diabetes within 6 months after non–COVID-19 respiratory infection.

At 1, 3, and 6 months after infection, risk of diagnosis of type 1 diabetes was greater among those infected with SARS-CoV-2, compared with those with non–COVID-19 respiratory infection (1 month: HR, 1.96; 3 months: HR, 2.10; and 6 months: HR, 1.83), and in subgroups of patients aged 0-9 years, a group unlikely to develop type 2 diabetes.

“In this study, new type 1 diabetes diagnoses were more likely to occur among pediatric patients with prior COVID-19 than among those with other respiratory infections (or with other encounters with health systems),” noted Ms. Kendall and coauthors. “Respiratory infections have previously been associated with onset of type 1 diabetes, but this risk was even higher among those with COVID-19 in our study, raising concern for long-term, post–COVID-19 autoimmune complications among youths.”

“The increased risk of new-onset type 1 diabetes after COVID-19 adds an important consideration for risk–benefit discussions for prevention and treatment of SARS-CoV-2 infection in pediatric populations,” they concluded.

A study from the Centers for Disease Control and Prevention published in January 2022, also concluded there was a link between COVID-19 and diabetes in children, but not with other acute respiratory infections. Children were 2.5 times more likely to be diagnosed with diabetes following a SARS-CoV-2 infection, it found.

However, the study has been criticized because it pooled all types of diabetes together and did not account for other health conditions, medications that can increase blood glucose levels, race, obesity, and other social determinants of health that might influence a child’s risk of acquiring COVID-19 or diabetes.

“I’ve no doubt that the CDC data were incorrect because the incidence rate for ... diabetes, even in those never exposed to COVID-19 infection, was 10 times the rate ever reported in the U.S.,” Dr. Colhoun said. “There’s no way these data are correct. I believe there was a confusion between incidence and prevalence of diabetes.”

“This paper caused a great deal of panic, especially among those who have a child with type 1diabetes, so we need to be very careful not to cause undue alarm until we have more definitive evidence in this arena,” she stressed.

However, she also acknowledged that the new Norwegian study was well conducted, and she has no methodological concerns about it, so “I think we just have to wait and see.”

Given the inconclusiveness on the issue, there is an ongoing CoviDiab registry collecting data on this very subject.

STOCKHOLM – It remains inconclusive whether SARS-CoV-2 infection predisposes children and adolescents to a higher risk of type 1 diabetes. Data from two new studies and a recently published research letter add to the growing body of knowledge on the subject, but still can’t draw any definitive conclusions.

The latest results from a Norwegian and a Scottish study both examine incidence of type 1 diabetes in young people with a history of SARS-CoV-2 infection and were reported at the annual meeting of the European Association for the Study of Diabetes.

A 60% increased risk for type 1 diabetes at least 31 days after SARS-CoV-2 infection (adjusted hazard ratio, 1.63) was found in the Norwegian study, while in contrast, the Scottish study only found an increased risk in the first few months of the pandemic, in 2020, but importantly, no association over a much longer time period (March 2020–November 2021).

In a comment on Twitter on the two studies presented at EASD, session moderator Kamlesh Khunti, MD, professor of primary care diabetes and vascular medicine at the University of Leicester, (England), said: “In summary, two studies showing no or weak association of type 1 diabetes with COVID.”

But new data in the research letter published in JAMA Network Open, based on U.S. figures, also found an almost doubling of type 1 diabetes in children in the first few months after COVID-19 infection relative to infection with other respiratory viruses.

Lead author of the Scottish study, Helen Colhoun, PhD, honorary public health consultant at Public Health Scotland, commented: “Data in children are variable year on year, which emphasizes the need to be cautious over taking a tiny snapshot.”

Nevertheless, this is “a hugely important question and we must not drop the ball. [We must] keep looking at it and maintain scientific equipoise. ... [This] reinforces the need to carry on this analysis into the future to obtain an unequivocal picture,” she emphasized.
 

Norwegian study: If there is an association, the risk is small

German Tapia, PhD, from the Norwegian Institute of Public Health, Oslo, presented the results of a study of SARS-CoV-2 infection and subsequent risk of type 1 diabetes in 1.2 million children in Norway.

Of these, 424,354 children had been infected with SARS-CoV-2, and there were 990 incident cases of type 1 diabetes.

“What we do know about COVID-19 in children is that the symptoms are mild and only a small proportion are hospitalized with more serious symptoms. But we do not know the long-term effects of COVID-19 infection because this requires a longer follow-up period,” remarked Dr. Tapia, adding that other viral infections are thought to be linked to the development of type 1 diabetes, in particular, respiratory infections.

The data were sourced from the Norwegian Emergency Preparedness Register for COVID-19, which gathers daily data updates including infections (positive and negative results for free-of-charge testing), diagnoses (primary and secondary care), vaccinations (also free of charge), prescribed medications, and basic demographics.

“We link these data using the personal identification number that every Norwegian citizen has,” explained Dr. Tapia.

He presented results from two cohorts: firstly, results in children only, including those tested for SARS-CoV-2 infection, and secondly, a full national Norwegian population cohort.

Regarding the first cohort, those under 18 years who tested positive for SARS-CoV-2 infection, from March 2020 to March 2022, had a significantly increased risk of type 1 diabetes at least 31 days after infection, with an adjusted hazard ratio of 1.63 (95% confidence interval, 1.08-2.47; P = .02). Adjustments were made for age, sex, non-Nordic country of origin, geographic area, and socioeconomic factors.

For children who developed type 1 diabetes within 30 days of a SARS-CoV-2 infection, the HR was 1.26 (95% CI, 0.72-2.19; P = .42), which did not reach statistical significance.

The diagnosis and management of refractory celiac disease remains challenging, but ongoing studies can provide the proper diagnostic criteria and identify the optimal management strategies, according to a new American Gastroenterological Association expert review published in Gastroenterology.

Celiac disease is present in about 1% of the U.S. population and can cause various symptoms, wrote Peter H. R. Green, MD, director of the Celiac Disease Center at Columbia University, New York, and colleagues. Adhering to a strict gluten-free diet can improve symptoms, normalize serum antibody levels, and reverse small bowel villous atrophy. However, persistent or recurrent symptoms and elevated celiac antibodies can persist in some patients after a year of trying a gluten-free diet, a condition called nonresponsive celiac disease. In some patients, this raises concern for refractory celiac disease, or RCD.

“RCD is believed to occur in only approximately 1% of patients with celiac disease, although this may be an overestimate, as data are obtained from referral centers,” the authors wrote.

RCD can be classified into two subtypes with different diagnostic criteria, prognoses, and therapy responses. The first, called RCD1, is characterized by villous atrophy but has intraepithelial lymphocytes similar to conventional celiac disease. The other, called RCD2, is characterized by aberrant clonal T-cell expansion in the intestinal tract and other organs, has a poorer prognosis than RCD1, and has a risk of developing ulcerative jejunoileitis or enteropathy-associated T-cell lymphoma.

The experts developed 10 clinical practice advice statements based on a review of the published literature and expert opinion.

First, in patients who have persistent or recurring symptoms, an initial celiac disease diagnosis should be confirmed through review of prior diagnostic testing, including serologies, endoscopies, and histologic findings. Celiac disease can overlap with other gastrointestinal conditions, and some pathologic findings aren’t specific to celiac disease. Results of serologic testing with tissue transglutaminase immunoglobulin A, deamidated gliadin peptide IgA and IgG, and endomysial antibodies should be reviewed or obtained if not previously performed.

Next, in those with confirmed but nonresponsive celiac disease, ongoing gluten ingestion should be excluded as a cause of symptoms with serologic testing, dietitian review, and potentially detection of immunogenic peptides in stool or urine samples. The authors noted that persistent gluten ingestion, whether intentional or inadvertent, accounts for 40%-50% of patients with nonresponsive celiac disease. In these cases, esophagogastroduodenoscopy and small bowel biopsies should be performed to look for persistent villous atrophy, which can also be caused by common variable immunodeficiency, autoimmune enteropathy, tropical sprue, and medication-induced enteropathy. Patients with villous atrophy due to other causes won’t respond to a gluten-free diet.

After excluding gluten, clinicians should perform a systematic evaluation for other potential causes of symptoms, including functional bowel disorders, lactose or fructose intolerance, microscopic colitis, pancreatic insufficiency, inflammatory bowel disease, and small intestinal bacterial growth. Irritable bowel syndrome, for instance, may contribute to persistent symptoms and respond to fermentable oligo-, di-, and monosaccharides and polyols (FODMAP) restriction. RCD should be strongly considered in patients with persistent symptoms or signs of malabsorption after the exclusion of the other causes.

To distinguish between the two subtypes of RCD and exclude enteropathy-associated T-cell lymphoma, clinicians should use flow cytometry, immunohistochemistry, and T-cell receptor rearrangement studies. RCD1 has a normal intraepithelial lymphocyte population, and RCD2 has an aberrant, clonal intraepithelial lymphocyte population. Consulting with a hematopathologist may be necessary to interpret these studies.

After RCD2 is diagnosed, complications such as enteropathy-associated T-cell lymphoma and ulcerative jejunoileitis should be excluded through small bowel imaging with capsule endoscopy and either computed tomography (CT) or magnetic resonance enterography. In general, the extent and severity of villous atrophy is greater in patients with RCD2, compared with RCD1.

In patients diagnosed with RCD, clinicians should complete a detailed nutritional assessment with investigation of micronutrient and macronutrient deficiencies. Check albumin as an independent prognostic factor. Then, try to correct deficiencies with oral supplements. Malnourished patients may need enteral support, and those with severe malnutrition due to malabsorption may need parenteral support.

So far, RCD management suggestions are based on small retrospective studies and expert opinion, with minimal prospective data and no Food and Drug Administration–approved therapies. The goals should be to improve symptoms and duodenal mucosal abnormalities, manage malnutrition, and prevent lymphoma. Glucocorticoids are considered first-line therapy, typically open-capsule budesonide given as 3 mg three times daily. Prednisone serves as an alternative with proven efficacy but a higher risk for adverse effects.

The optimal choice for second-line therapy is unknown, but the addition of an immunosuppressant agent to steroids appears to be effective in RCD1, including azathioprine, mercaptopurine, and tioguanine. The best treatment for RCD2 is unknown, though clinical response has been reported with steroids, and cladribine has been well tolerated in some patients.

Patients with RCD who don’t respond to steroids may benefit from referral to a center with expertise for management or evaluation for inclusion in clinical trials. Frequent medical visits are advised until the disease is well controlled, with regular follow-up after that. 

Ultimately, “patients with RCD benefit from evaluation and regular follow-up by a multidisciplinary team, including gastroenterologists and dietitians, to assess clinical and histologic response to therapy,” the authors wrote. “Identify local experts with expertise in celiac disease to assist with management.”

The authors reported no grant support or funding sources for this study. One author has received research report from Freenome, and another is on the celiac disease advisory board for Takeda. The remaining authors disclosed no conflicts.

After excluding gluten, clinicians should perform a systematic evaluation for other potential causes of symptoms, including functional bowel disorders, lactose or fructose intolerance, microscopic colitis, pancreatic insufficiency, inflammatory bowel disease, and small intestinal bacterial growth. Irritable bowel syndrome, for instance, may contribute to persistent symptoms and respond to fermentable oligo-, di-, and monosaccharides and polyols (FODMAP) restriction. RCD should be strongly considered in patients with persistent symptoms or signs of malabsorption after the exclusion of the other causes.

To distinguish between the two subtypes of RCD and exclude enteropathy-associated T-cell lymphoma, clinicians should use flow cytometry, immunohistochemistry, and T-cell receptor rearrangement studies. RCD1 has a normal intraepithelial lymphocyte population, and RCD2 has an aberrant, clonal intraepithelial lymphocyte population. Consulting with a hematopathologist may be necessary to interpret these studies.

After RCD2 is diagnosed, complications such as enteropathy-associated T-cell lymphoma and ulcerative jejunoileitis should be excluded through small bowel imaging with capsule endoscopy and either computed tomography (CT) or magnetic resonance enterography. In general, the extent and severity of villous atrophy is greater in patients with RCD2, compared with RCD1.

In patients diagnosed with RCD, clinicians should complete a detailed nutritional assessment with investigation of micronutrient and macronutrient deficiencies. Check albumin as an independent prognostic factor. Then, try to correct deficiencies with oral supplements. Malnourished patients may need enteral support, and those with severe malnutrition due to malabsorption may need parenteral support.

So far, RCD management suggestions are based on small retrospective studies and expert opinion, with minimal prospective data and no Food and Drug Administration–approved therapies. The goals should be to improve symptoms and duodenal mucosal abnormalities, manage malnutrition, and prevent lymphoma. Glucocorticoids are considered first-line therapy, typically open-capsule budesonide given as 3 mg three times daily. Prednisone serves as an alternative with proven efficacy but a higher risk for adverse effects.

The optimal choice for second-line therapy is unknown, but the addition of an immunosuppressant agent to steroids appears to be effective in RCD1, including azathioprine, mercaptopurine, and tioguanine. The best treatment for RCD2 is unknown, though clinical response has been reported with steroids, and cladribine has been well tolerated in some patients.

Patients with RCD who don’t respond to steroids may benefit from referral to a center with expertise for management or evaluation for inclusion in clinical trials. Frequent medical visits are advised until the disease is well controlled, with regular follow-up after that. 

Ultimately, “patients with RCD benefit from evaluation and regular follow-up by a multidisciplinary team, including gastroenterologists and dietitians, to assess clinical and histologic response to therapy,” the authors wrote. “Identify local experts with expertise in celiac disease to assist with management.”

The authors reported no grant support or funding sources for this study. One author has received research report from Freenome, and another is on the celiac disease advisory board for Takeda. The remaining authors disclosed no conflicts.

The COVID-19 pandemic has been associated with the development of anorexia nervosa in Canadian children and adolescents, data suggest.

Preliminary results of the Canadian Paediatric Surveillance Program (CPSP) indicate that the pandemic has been a precipitating factor in the development of anorexia nervosa in almost half of children and adolescents studied. The pandemic also has precipitated hospitalizations for anorexia in more than one-third of cases.

“Data globally, and certainly our data here in Canada, have shown a real increase in health care utilization with the onset of the COVID-19 pandemic,” study author Debra Katzman, MD, professor of pediatrics at the Hospital for Sick Children in Toronto and the University of Toronto, said in an interview. “And when I talk about health care utilization, I’m talking about hospitalizations for eating disorders.”

The data were included in the 2021 results of the CPSP.
 

Focus on appearance

CPSP is a collaboration between the Public Health Agency of Canada and the Canadian Pediatric Society that consists of a network of 2,800 pediatricians and pediatric subspecialists across Canada. The latest results include surveillance studies on 14 diseases and conditions, with data collected during various periods.

From April 2020 to May 2021, researchers identified 1,800 COVID-19 cases in children and collected detailed information on 1,456 of them, including 405 cases hospitalized with pediatric inflammatory multisystem syndrome (PIMS). The median age of hospitalized cases was 3.2 years for SARS-CoV-2 infection and 5.4 years for PIMS.

Dr. Katzman and colleagues observed 118 first-time hospitalizations for anorexia nervosa between Sept. 1 and Dec. 31, 2021. More than 90% of reported cases were female, with 66% of verified cases in teens aged 14-17 years and the remainder in adolescents aged 11-13 years.

In 49% of cases, the reporting physician identified the COVID-19 pandemic as a precipitating factor in the development of anorexia nervosa. In 37% of cases, the reporting physician identified the pandemic as having precipitated the anorexia-related hospitalization.

Last year, a cross-sectional analysis of children in Canada reported that monthly hospitalizations for anorexia nervosa increased from 7.5 to 20 from March through November 2020. The monthly rate in the CPSP study was closer to 30 for first-time hospitalizations.

Dr. Katzman said that the findings about anorexia nervosa didn’t surprise her. “There was so much disruption and [so many] restrictions to young peoples’ daily routines – closures of schools and recreational activities – they lost regular connection with their peers, and they lost extracurricular and social activities,” she said. “That led to heightened anxiety and depression and really a lack of control.”

Adolescents and teens were also spending more time on social media than they were before the pandemic, she noted. “They were looking at themselves all the time, so they were getting preoccupied with their body image. There was a heightened focus on appearance, and I think that things like public-health mitigation strategies – things like hand washing, social distancing, mask wearing – may have impacted the psychological well-being of young people.”

The closure of outpatient facilities, long waiting lists to get into facilities that were opened, and “coronaphobia” about going to physicians’ offices and emergency departments compounded the problem, Dr. Katzman added.

The long-term effects of COVID and eating disorders in children are unknown, Dr. Katzman said. “This is sort of a wake-up call for the health care system that during times of stress or pandemics or crises, these kinds of things can happen, and we need to be prepared to provide the resources for vulnerable populations moving forward,” she said.
 

Heightened anxiety

Commenting on the data, Margaret Thew, APNP, director of the eating disorders program at Children’s Wisconsin in Milwaukee, said that isolation due to school closures and negative social media messages created the “perfect storm” for eating disorders in adolescents and teenagers because of higher rates of anxiety and depression. Ms. Thew was not involved in the research.

The storm is not over yet, she said. “What everyone needs to keep in mind is that we still have this very heightened state of anxiety and depression ... for adolescents, teenagers, and preteens alike,” Ms. Thew said in an interview, “and we know that many of them are not coping with their anxiety very well.”

In her experience, since the start of the pandemic, the average age of pediatric patients with eating disorders declined from 16 to 15 years, and the youngest age declined from 12 to 11 years.

Overall, the CPSP results show that children are affected by mental health issues at an earlier age than before the pandemic, said Ms. Thew. “Years ago, we wouldn’t have thought that an 8-year-old needed to be screened for some of these risk factors, but now we’re definitely getting more younger children who are struggling, and I think it’s taking too long for them to get the care they need because it’s being overlooked,” she said.

The report was funded by the Public Health Agency of Canada, Health Canada, Alberta Children’s Hospital Research Institute, Bethanys Hope Foundation, CHEO Research Institute, and Children’s Hospital Research Institute of Manitoba. Dr. Katzman and Ms. Thew have no relevant disclosures.

This transcript of Impact Factor with F. Perry Wilson has been edited for clarity.

It was 100 years ago when Leonard Thompson, age 13, received a reprieve from a death sentence. Young master Thompson had type 1 diabetes, a disease that was uniformly fatal within months of diagnosis. But he received a new treatment, insulin, from a canine pancreas. He would live 13 more years before dying at age 26 of pneumonia.

The history of type 1 diabetes since that time has been a battle on two fronts: First, the search for a cause of and cure for the disease; second, the effort to make the administration of insulin safer, more reliable, and easier.

The past 2 decades have seen a technological revolution in type 1 diabetes care, with continuous glucose monitors decreasing the need for painful finger sticks, and insulin pumps allowing for more precise titration of doses.

The dream, of course, has been to combine those two technologies, continuous glucose monitoring and insulin pumps, to create so-called closed-loop systems – basically an artificial pancreas – that would obviate the need for any intervention on the part of the patient, save the occasional refilling of an insulin reservoir.

We aren’t there yet, but we are closer than ever.

Closed-loop systems for insulin delivery, like the Tandem Control IQ system, are a marvel of technology, but they are not exactly hands-free. Users need to dial in settings for their insulin usage, count carbohydrates at meals, and inform the system that they are about to eat those meals to allow the algorithm to administer an appropriate insulin dose.

The perceived complexity of these systems may be responsible for why there are substantial disparities in the prescription of closed-loop systems. Kids of lower socioeconomic status are dramatically less likely to receive these advanced technologies. Providers may feel that patients with lower health literacy or social supports are not “ideal” for these technologies, even though they lead to demonstrably better outcomes.

That means that easier might be better. And a “bionic pancreas,” as reported in an article from The New England Journal of Medicine, is exactly that.

Broadly, it’s another closed-loop system. The bionic pancreas integrates with a continuous glucose monitor and administers insulin when needed. But the algorithm appears to be a bit smarter than what we have in existing devices. For example, patients do not need to provide any information about their usual insulin doses – just their body weight. They don’t need to count carbohydrates at meals – just to inform the device when they are eating, and whether the meal is the usual amount they eat, more, or less. The algorithm learns and adapts as it is used. Easy.

And in this randomized trial, easy does it.

A total of 219 participants were randomized in a 2:1 ratio to the bionic pancreas or usual diabetes care, though it was required that control participants use a continuous glucose monitor. Participants were as young as 6 years old and up to 79 years old; the majority were White and had a relatively high household income. The mean A1c was around 7.8% at baseline.

By the end of the study, the A1c was significantly improved in the bionic pancreas group, with a mean of 7.3% vs. 7.7% in the usual-care group.

This effect was most pronounced in those with a higher A1c at baseline.

People randomized to the bionic pancreas also spent more time in the target glucose range of 70-180 mg/dL.

All in all, the technology that makes it easy to manage your blood sugar, well, made it easy to manage your blood sugar.

But new technology is never without its hiccups. Those randomized to the bionic pancreas had a markedly higher rate of adverse events (244 events in 126 people compared with 10 events in 8 people in the usual-care group.)

This is actually a little misleading, though. The vast majority of these events were hyperglycemic episodes due to infusion set failures, which were reportable only in the bionic pancreas group. In other words, the patients in the control group who had an infusion set failure (assuming they were using an insulin pump at all) would have just called their regular doctor to get things sorted and not reported it to the study team.

Nevertheless, these adverse events – not serious, but common – highlight the fact that good software is not the only key to solving the closed-loop problem. We need good hardware too, hardware that can withstand the very active lives that children with type 1 diabetes deserve to live.

In short, the dream of a functional cure to type 1 diabetes, a true artificial pancreas, is closer than ever, but it’s still just a dream. With iterative advances like this, though, the reality may be here before you know it.

Developmental language disorder (DLD) is characterized by receptive or expressive language difficulties or both. Children with the neurodevelopmental condition “struggle to comprehend and use their native language for no obvious reason,” said the authors of a new study. This leads to problems with grammar, vocabulary, and holding conversations, and in turn an increased risk of “difficulties when learning to read, underachieving academically, being unemployed, and facing social and mental health challenges.”

The condition is common and estimated to affect 7% of children – approximately two in every classroom – but is “underrecognized” said the authors.

Saloni Krishnan, PhD, reader at Royal Holloway, University of London, who led the study as a research fellow at the University of Oxford, England, explained: “DLD is a relatively unknown and understudied condition, unlike better known neurodevelopmental conditions such as ADHD, dyslexia, or autism.”

It is suspected that children with DLD may have differences in areas of the brain involved with learning habits and rules. “Although we know that DLD does not result from gross neural lesions, we still do not have a clear picture of how brain anatomy differs in children with DLD,” the authors highlighted.
 

Language learning difficulties linked to brain differences

For their study, published in eLife, researchers used an MRI technique called multiparameter mapping (MPM) to investigate microstructural neural differences in children with DLD. The technique measures the properties of brain tissue and is particularly useful for measuring the amounts of myelin.

“Understanding the neural basis of DLD is particularly challenging given the developmental nature of the disorder, as well as the lack of animal models for understanding language,” explained the authors. However, they pointed out that MPM allows an “unparalleled in vivo method” to investigate microstructural neural changes in children with DLD.

Kate Watkins, PhD, professor of cognitive neuroscience at the University of Oxford and senior author, said: “This type of scan tells us more about the makeup or composition of the brain tissue in different areas.”

As part of the Oxford Brain Organisation in Language Development (OxBOLD) study, the researchers recruited and tested 175 children between the ages of 10 and 15 years. Subsequently, 56 children with typical language development and 33 children with DLD were scanned using MPM.

The researchers compared the two groups and found that children with DLD have less myelin in parts of the brain responsible for speaking, listening, and learning rules and habits.

Specifically, maps of magnetization transfer saturation (MTsat) – which index myelin – in children with DLD showed reductions in MTsat values in the caudate nucleus bilaterally, and in the left ventral sensorimotor cortex and Heschl’s gyrus.

“Our findings using this protocol suggest that the caudate nucleus, as well as regions in the wider speech and language network, show alterations in myelin in children with DLD,” explained the authors.

“Given myelin’s role in enabling fast and reliable communication in the brain, reduced myelin content may explain why children with DLD struggle with speech and language processing,” they highlighted.
 

Significant advance in DLD understanding

The study findings established changes in striatal and cortical myelin as a “neural basis for DLD,” explained the journal editor, who highlighted that this was a “significant advance” in the understanding of DLD. “These brain differences may explain the poorer language outcomes in this group,” the authors said.

The findings “strongly point” to a role for the striatum in the development of DLD, and this role is likely to be in the “learning of habits and sequences,” the authors said.

They pointed out, however, that myelin patterns can change over development, and that myelination can be observed after successful training. “It is important to assess whether these differences in myelin persist over development in DLD, and if they can be targeted through training using behavioral interventions,” they emphasized.

Professor Watkins commented: “The findings might help us understand the pathways involved at a biological level and ultimately allow us to explain why children with DLD have problems with language learning.”

A spokesperson for the RADLD (Raising Awareness of Developmental Language Disorder) organization, commented: “Developmental language disorder has long been understood to have a neurological basis; however, these differences in the brain development have received limited attention in research.” It added that utilizing new technology helps to better understand the “potential neurological differences” experienced by people with DLD.

More studies are needed to determine if these brain differences cause language problems and how or if experiencing language difficulties could cause these changes in the brain, explained the authors. They hoped that further research may help scientists find new treatments that target these brain differences.

Developmental language disorder (DLD) is characterized by receptive or expressive language difficulties or both. Children with the neurodevelopmental condition “struggle to comprehend and use their native language for no obvious reason,” said the authors of a new study. This leads to problems with grammar, vocabulary, and holding conversations, and in turn an increased risk of “difficulties when learning to read, underachieving academically, being unemployed, and facing social and mental health challenges.”

The condition is common and estimated to affect 7% of children – approximately two in every classroom – but is “underrecognized” said the authors.

People at increased risk for syphilis – including asymptomatic, nonpregnant adolescents and adults who have ever been sexually active and are at high risk for the disease – should be screened for it, according to a reaffirmation by the United States Preventive Services Task Force of its 2016 recommendation of syphilis screening for people at increased risk for infection.

“Using a reaffirmation process, the USPSTF concludes with high certainty that there is a substantial net benefit of screening for syphilis infection in nonpregnant persons who are at increased risk for infection,” the authors, led by Carol M. Mangione, MD, MSPH, of the University of California, Los Angeles, wrote in JAMA.

Reported cases in the United States of primary and secondary syphilis – a sexually transmitted infection caused by the bacterium Treponema pallidum that can damage the brain, nerves, eyes, and cardiovascular system if left untreated – increased from a low of 2.1 cases per 100,000 people in 2000 and 2001 to 11.9 cases per 100,000 in 2019, the authors reported. In 2019, men accounted for 83% of all primary and secondary syphilis cases, and men who have sex with men (MSM) accounted for 57% of all primary and secondary syphilis cases in men. Screening and follow-up treatment can cure syphilis and prevent complications.

To help them evaluate the effectiveness and safety of screening, the USPSTF authors reviewed the literature and visually displayed key questions and linkages to interventions and outcomes, Michelle L. Henninger, PhD, Sarah I. Bean, MPH, and Jennifer S. Lin, MD, MCR, of the Kaiser Permanente Evidence-based Practice Center in Portland, Ore., noted in a related evidence report of the post-2016 recommendation data.

Reaffirming its 2016 recommendation, the USPSTF now advises clinicians to:

Assess risk:

• Clinicians should know how common syphilis is in their community and assess their patient’s individual risk.
• Risk for syphilis is higher in MSM, people with HIV infection or other STIs, and those who use illicit drugs or have a history of incarceration, sex work, or military service.

Screen and confirm by testing:

• Traditional screening algorithm: Start with a nontreponemal test such as Venereal Disease Research Laborator or rapid plasma reagin. If positive, confirm result with a treponemal antibody detection test, such as T. pallidum particle agglutination.
• Reverse sequence algorithm: Screen with an initial automated treponemal test such as enzyme-linked or chemiluminescence immunoassay. If positive, confirm result with a nontreponemal test.

Consider screening interval:

• Evidence on optimal screening intervals is limited for the general population, but MSM and people with HIV may benefit from screening yearly or every 3-6 months if they remain at high risk.

The authors acknowledged that primary and secondary syphilis rates are higher in Blacks, Hispanics, Native Americans/Alaska Native, and Native Hawaiians/Pacific Islanders, and that the disparities are primarily driven by social determinants of health including differences in income, education, and access to coverage and care.

They added that differences in sexual networks also play a role in disparities and that sexually active people in communities with higher STI rates may be more likely to become infected.
 

More testing, treatment, and research are needed

Four experts welcomed the reaffirmation.

“It is important and necessary that the task force has chosen to reaffirm their syphilis screening recommendations, given the continued increase in sexually transmitted infections in the U.S. since the 2016 published recommendations,” Judith A. O’Donnell, MD, director of the department of infection prevention and control at Penn Presbyterian Medical Center in Philadelphia, said in an interview.

“Awareness of the ongoing incidence, understanding of the importance of screening in interrupting transmission, and getting people diagnosed and treated before serious complications are key,” she added.

Heidi Gullettt, MD, MPH, associate director of the Center for Community Health Integration at Case Western Reserve University, Cleveland, said: “The reaffirmation document authors demonstrated a comprehensive review of high-quality studies and epidemiologic data.

“Primary care clinicians rely on USPSTF recommendations to help prioritize evidence-based prevention in practice, so this reaffirmation is a critical step to remind us of the importance of regularly assessing risk and screening with a readily available screening test in the office,” she added.

Testing during office visits is not easy, Dr. Gullettt said, because of competing priorities, stigma associated with STIs, and testing and treatment costs. 

“Under the Affordable Care Act, USPSTF screening recommendations are supposed to be covered without cost sharing by patients. This should be the case for syphilis screening,” Dr. Gullett pointed out. “Patients are often reluctant to do screening because of cost.”

Michael Anthony Moody, MD, director of the Collaborative Influenza Vaccine Innovation Center at Duke University, Durham, N.C., said that the true incidence and prevalence of syphilis is unknown.

“The more we test, the more accurate our data will be,” he said. “Syphilis can hide in plain sight, has symptoms that mimic many other diseases, and is usually not diagnosed. Reaffirming that testing for syphilis is important reminds providers that this is a key test for their patient’s health.”

Aniruddha Hazra, MD, medical director of the University of Chicago Medicine Sexual Wellness Clinic, noted that the United States is in a syphilis epidemic.

“Screening asymptomatic people at risk for syphilis is important, but without comprehensive education and training of primary care providers on how to address STIs and sexual health, these recommendations fall flat,” he said.

In an accompanying editorial, Susan Tuddenham, MD, MPH; and Khalil G. Ghanem, MD, PhD, of Johns Hopkins University, Baltimore, urged that funding to develop novel syphilis diagnostics be prioritized, “just as there has been for development of syphilis vaccines, which are still many years from becoming a reality.”

“Relying on emerging biomedical prevention interventions that hold promise, such as doxycycline postexposure prophylaxis, without concomitant robust screening strategies will not lead to syphilis control. Failure to modernize screening strategies for syphilis will also mean failure to control this infection,” they cautioned.

The authors of the recommendation statement and the evidence report, as well as Dr. O’Donnell, Dr. Gullettt, Dr. Moody, and Dr. Hazra, who were not involved in the study, reported no relevant financial relationships. Dr. Tuddenham reported financial relationships with the pharmaceutical and publishing industries. Dr. Ghanem reported financial relationships with the publishing industry. The research was federally funded.

Herpes to the rescue

Let’s face it: When people hear the word “herpes,” their first thoughts are not positive. But what if herpes could be a hero?

Scientists have found a way to make a strain of herpes that kills cancer because, hey, it’s 2022, and anything is possible. Trials have been going well and this seems like a safe and effective way to fight cancer.

Aunt_Spray/Thinkstock

Viruses may be one of our oldest enemies, but it’s also been said that the enemy of my enemy is my friend. So why not make herpes the enemy of cancer, thereby turning it into our friend? The genetically modified herpes virus is injected directly into tumors, where it destroys cancer cells from within. But wait, there’s more! The patient’s immune system also senses the virus and springs into action against it and the cancer in which it is residing.

During the phase 1 trial, three of the nine patients saw tumor reduction and the therapy proved safe as well. Future trials will be able to more specifically target various cancer types and make the treatment better. For once, we are rooting for you, herpes.
 

A breath of not-so-fresh air

There’s nothing quite like that first real warm day of spring. You can finally open the windows and clear out the old stuffy air that’s been hanging around all winter long. It’s a ritual that’s now backed up with some science in the form of a new study. Turns out that there’s actually a fair amount of smog in the average home. That’s right, smog’s not just for the big city anymore.

PxHere

As part of the HOMEChem project, a whole host of scientists gathered together under one roof in a typical suburban house and immediately started doing chores. Cooking, cleaning, the works. No, it wasn’t because they had trashed the place the night before. They had set up instrumentation all around the house to measure the chemical makeup of the air inside. A scientist’s idea of a wild party.

The results are perhaps not all that surprising, but interesting nonetheless. Your homemade smog certainly won’t kill you, but there’s both an increased amount and higher concentration of airborne toxins in indoor air, compared with outdoors. Benzene and formaldehyde were common, as were acrolein (a pulmonary toxicant emitted by lumber and burning fats) and isocyanic acid (which can react with proteins in the human body). The researchers noted that most of these chemicals can be removed with proper ventilation.

Although cleaning is certainly responsible for a fair share of the chemicals, cooking generally produced more toxic compounds, similar to what’s found in wildfire smoke. One of the researchers said this makes sense, since a wildfire can be considered an “extreme form of cooking.” Scientists may not know how to party, but their idea of a barbecue sounds … interesting. We’re looking forward to an upcoming study out of California: Can a 1-million acre wildfire adequately cook a ribeye steak?
 

We’re dying to try composting ... with humans, that is

We here at LOTME are not really fans of politicians, except as objects of ridicule. That is kind of fun. Whether we’re watching Fox News, listening to NPR, or reading Vladimir Putin’s fashion blog, one thing remains clear: If you want actual information, don’t ask a politician.

There are, of course, always exceptions, and we just found one: California state representative Cristina Garcia. Rep. Garcia sponsored a bill just signed into law by Gov. Gavin Newsom that legalizes the practice of human composting, the reduction of remains by “placing bodies in individual vessels and fostering gentle transformation into a nutrient-dense soil.”

Since we’ve written about this sort of thing before – Washington was the first state to legalize the process back in 2019 – we’re more interested now in what Rep. Garcia told NBC News while describing her motivation: “I’ve always wanted to be a tree. The idea of having my family sitting under my shade one day – that brings a lot of joy.” How great is that? Tree-hugging is just not enough. Be the tree.

California is the fifth state to provide its residents with the human composting option, the other three being Colorado, Oregon, and Vermont. The process “typically involves putting a body into a steel vessel, then covering it with organic materials like straw, wood chips and alfalfa. Microbes break down the corpse and the plant matter, transforming the various components into nutrient-rich soil in roughly 30 days,” Smithsonian Magazine explained.

We just happen to have some good news for Rep. Garcia about that wanting-to-be-a-tree business. She’s already pretty close. For more on that, we go to our correspondent from beyond the grave, Carl Sagan, who shares a thought about trees. And no, we couldn’t just write out his quote here. You have to hear it in Dr. Sagan’s own voice.
 

That’ll be one pandemic with extra distress. Hold the goals

When the COVID-19 pandemic first hit it put a lot of stuff on hold for everyone. Couldn’t eat inside at your favorite restaurant, attend that long-awaited concert, or travel out of the country. Those were all pretty bad, but it was the disruption of pursuing long-term goals that seemed to have the most effect on people’s mental health.

Investigators from the University of Waterloo (Ont.) looked at how putting such goals on hold affected people’s mental well-being. The study’s 226 participants were asked about their “COVID-frozen” goals and the degree to which they were able to actively pursue each goal and how committed they were to achieving it.

What they found was that the participants’ COVID-frozen goals were associated with feelings of psychological distress, such as anxiety, depressive symptoms, stress, and lowered life satisfaction. It was only when participants were able to disengage from goal rumination that well-being was impacted positively.

“Goal rumination is compulsive and can aggravate worries and frustrations while also taking away mental resources from other goals,” Candice Hubley, lead author and a PhD candidate in psychology, said in a written statement. So in short, you’re only stressing yourself out more about something that is far off in the distance when you could be focusing more on short-term, tangible goals instead.

Now, no one is saying to give up on your goals. Just take them one at a time. You’ll have better life satisfaction and your COVID-frozen goals will thaw out before you know it.

Herpes to the rescue

Let’s face it: When people hear the word “herpes,” their first thoughts are not positive. But what if herpes could be a hero?

Scientists have found a way to make a strain of herpes that kills cancer because, hey, it’s 2022, and anything is possible. Trials have been going well and this seems like a safe and effective way to fight cancer.

Viruses may be one of our oldest enemies, but it’s also been said that the enemy of my enemy is my friend. So why not make herpes the enemy of cancer, thereby turning it into our friend? The genetically modified herpes virus is injected directly into tumors, where it destroys cancer cells from within. But wait, there’s more! The patient’s immune system also senses the virus and springs into action against it and the cancer in which it is residing.

During the phase 1 trial, three of the nine patients saw tumor reduction and the therapy proved safe as well. Future trials will be able to more specifically target various cancer types and make the treatment better. For once, we are rooting for you, herpes.
 

A breath of not-so-fresh air

There’s nothing quite like that first real warm day of spring. You can finally open the windows and clear out the old stuffy air that’s been hanging around all winter long. It’s a ritual that’s now backed up with some science in the form of a new study. Turns out that there’s actually a fair amount of smog in the average home. That’s right, smog’s not just for the big city anymore.

As part of the HOMEChem project, a whole host of scientists gathered together under one roof in a typical suburban house and immediately started doing chores. Cooking, cleaning, the works. No, it wasn’t because they had trashed the place the night before. They had set up instrumentation all around the house to measure the chemical makeup of the air inside. A scientist’s idea of a wild party.

The results are perhaps not all that surprising, but interesting nonetheless. Your homemade smog certainly won’t kill you, but there’s both an increased amount and higher concentration of airborne toxins in indoor air, compared with outdoors. Benzene and formaldehyde were common, as were acrolein (a pulmonary toxicant emitted by lumber and burning fats) and isocyanic acid (which can react with proteins in the human body). The researchers noted that most of these chemicals can be removed with proper ventilation.

Although cleaning is certainly responsible for a fair share of the chemicals, cooking generally produced more toxic compounds, similar to what’s found in wildfire smoke. One of the researchers said this makes sense, since a wildfire can be considered an “extreme form of cooking.” Scientists may not know how to party, but their idea of a barbecue sounds … interesting. We’re looking forward to an upcoming study out of California: Can a 1-million acre wildfire adequately cook a ribeye steak?

This discussion was recorded on Aug. 31, 2022. This transcript has been edited for clarity.

Robert Glatter, MD: Welcome. I’m Dr. Robert Glatter, medical advisor for Medscape Emergency Medicine. Today we have Dr. Paul Christo, a pain specialist in the Division of Pain Medicine at Johns Hopkins University School of Medicine in Baltimore, Maryland, and host of the national radio show Aches and Gains on SiriusXM Radio, joining us to discuss the ongoing and worsening fentanyl crisis in the U.S.

Welcome, Dr Christo.

Paul J. Christo, MD, MBA: Thanks so much for having me.

Dr. Glatter: I want to begin with a sobering statistic regarding overdoses. There were over 107,000 overdose deaths in the U.S. from 2020 to 2021, of which over two thirds involved the synthetic opiate fentanyl, based on recent data from the CDC.

Let’s start by having you explain how deadly fentanyl is in terms of its potency compared with morphine and heroin.

Dr. Christo: Fentanyl is considered a synthetic opioid. It’s not a naturally occurring opioid like morphine, for example, or codeine. We use this drug, fentanyl, often in the anesthesia well. We’ve used it for many years as an anesthetic for surgery very safely. In the chronic pain world, we’ve used it to help reduce chronic pain in the form of a patch.

What we’re seeing now, though, is something entirely different, which is the use of synthetic fentanyl as a mind- and mood-altering substance for those who don’t have pain, and essentially those who are buying this off the street. Fentanyl is about 80-100 times more potent than morphine, so you can put that in perspective in terms of its danger.

Dr. Glatter: Let me have you take us through an evolution of the opioid crisis from the 1990s, from long-acting opioid OxyContin, which was approved in 1995, to where we are now. There are different phases. If you could, educate our audience on how we got to where fentanyl is now the most common opiate involved in drug overdoses.

Dr. Christo: It really stems from the epidemic related to chronic pain. We have over 100 million people in the United States alone who suffer from chronic pain. Most chronic pain, sadly, is undertreated or untreated. In the ‘90s, in the quest to reduce chronic pain to a better extent, we saw more and more literature and studies related to the use of opioids for noncancer pain (e.g., for lower back pain).

There were many primary care doctors and pain specialists who started using opioids, probably for patients who didn’t really need it. I think it was done out of good conscience in the sense that they were trying to reduce pain. We have other methods of pain relief, but we needed more. At that time, in the ‘90s, we had a greater use of opioids to treat noncancer pain.

Then from that point, we transitioned to the use of heroin. Again, this isn’t among the chronic pain population, but it was the nonchronic pain population that starting using heroin. Today we see synthetic fentanyl.
 

Addressing the synthetic opioid crisis

Dr. Glatter: With fentanyl being the most common opiate we’re seeing, we’re having problems trying to save patients. We’re trying to use naloxone, but obviously in increasing amounts, and sometimes it’s not adequate and we have to intubate patients.

In terms of addressing this issue of supply, the fentanyl is coming from Mexico, China, and it’s manufactured here in the United States. How do we address this crisis? What are the steps that you would recommend we take?

Dr. Christo: I think that we need to better support law enforcement to crack down on those who are manufacturing fentanyl in the United States, and also to crack down on those who are transporting it from, say, Mexico – I think it’s primarily coming from Mexico – but from outside the United States to the United States. I feel like that’s important to do.

Two, we need to better educate those who are using these mind- and mood-altering substances. We’re seeing more and more that it’s the young-adult population, those between the ages of 13 and 25, who are starting to use these substances, and they’re very dangerous.

Dr. Glatter: Are these teens seeking out heroin and it happens to be laced with fentanyl, or are they actually seeking pure fentanyl? Are they trying to buy the colorful pills that we know about? What’s your experience in terms of the population you’re treating and what you could tell us?

Dr. Christo: I think it’s both. We’re seeing young adults who are interested in the use of fentanyl as a mind- and mood-altering substance. We’re also seeing young and older adults use other drugs, like cocaine and heroin, that are laced with fentanyl, and they don’t know it. That’s exponentially more dangerous.

Fentanyl test strips

Dr. Glatter: People are unaware that there is fentanyl in what they’re using, and it is certainly leading to overdoses and deaths. I think that parents really need to be aware of this.

Dr. Christo: Yes, for sure. I think we need better educational methods in the schools to educate that population that we’re talking about (between the ages of 13 and 25). Let them know the dangers, because I don’t think they’re aware of the danger, and how potent fentanyl is in terms of its lethality, and that you don’t need very much to take in a form of a pill or to inhale or to inject intravenously to kill yourself. That is key – education at that level – and to let those who are going to use these substances (specifically, synthetic fentanyl) know that they should consider the use of fentanyl test strips.

Fentanyl test strips would be primarily used for those who are thinking that they’re using heroin but there may be fentanyl in there, or methamphetamine and there may be fentanyl, and they don’t know. The test strip gives them that knowledge.

The other harm reduction strategies would be the use of naloxone, known as Narcan. That’s a lifesaver. You just have to spritz it into the nostril. You don’t do it yourself if you’re using the substance, but you’ve got others who can do it for you. No question, that’s a lifesaver. We need to make sure that there’s greater availability of that throughout the entire country, and we’re seeing some of that in certain states. In certain states, you don’t need a prescription to get naloxone from the pharmacy.

Dr. Glatter: I think it’s so important that it should be widely available. Certainly, the COVID-19 pandemic exacerbated the number of overdoses we saw. Are overdoses coming down or are we still at a level that’s close to 2020?

Dr. Christo: Unfortunately, we’re still seeing the same level, if not seeing it escalate. Certainly, the pandemic, because of the economic cost associated with the pandemic – loss of employment, underemployment – as well as the emotional stress of the pandemic led many people to use substances on the street in order to cope. They’re coping mechanisms, and we really haven’t seen it abate quite yet.

Dr. Glatter: Do you have a message for the lawmakers on Capitol Hill as to what we can do regarding the illegal manufacturing and distribution, how we can really crack down? Are there other approaches that we could implement that might be more tangible?

Dr. Christo: Yes. No. 1 would be to support law enforcement. No. 2 would be to create and make available more overdose prevention centers. The first was in New York City. If you look at the data on overdose prevention centers, in Canada, for example, they’ve seen a 35% reduction in overdose deaths. These are places where people who are using can go to get clean needles and clean syringes. This is where people basically oversee the use of the drug and intervene if necessary.

It seems sort of antithetical. It seems like, “Boy, why would you fund a center for people to use drugs?” The data from Canada and outside Canada are such that it can be very helpful. That would be one of my messages to lawmakers as well.
 

Vaccines to combat the synthetic opioid crisis

Dr. Glatter: Do you think that the legislators could approach some of these factories as a way to crack down, and have law enforcement be more aggressive? Is that another possible solution?

Dr. Christo: It is. Law enforcement needs to be supported by the government, by the Biden administration, so that we can prevent the influx of fentanyl and other drugs into the United States, and also to crack down on those in the United States who are manufacturing these drugs – synthetic fentanyl, first and foremost – because we’re seeing a lot of deaths related to synthetic fentanyl.

Also, we’re seeing — and this is pretty intriguing and interesting – the use of vaccines to help prevent overdose. The first human trial is underway right now for a vaccine against oxycodone. Not only that, but there are other vaccines that are in animal trials now against heroin, cocaine, or fentanyl. There’s hope there that we can use vaccines to also help reduce deaths related to overdose from fentanyl and other opioids.

Dr. Glatter: Do you think this would be given widely to the population or only to those at higher risk?

Dr. Christo: It would probably be targeting those who are at higher risk and have a history of drug abuse. I don’t think it would be something that would be given to the entire population, but it certainly could be effective, and we’re seeing encouraging results from the human trial right now.

Dr. Glatter: That’s very intriguing. That’s something that certainly could be quite helpful in the future.

One thing I did want to address is law enforcement and first responders who have been exposed to dust, or inhaled dust possibly, or had fentanyl on their skin. There has been lots of controversy. The recent literature has dispelled the controversy that people who had supposedly passed out and required Narcan after exposure to intact skin, or even compromised skin, had an overdose of fentanyl. Maybe you could speak to that and dispel that myth.

Dr. Christo: Yes, I’ve been asked this question a couple of times in the past. It’s not sufficient just to have contact with fentanyl on the skin to lead to an overdose. You really need to ingest it. That is, take it by mouth in the form of a pill, inhale it, or inject it intravenously. Skin contact is very unlikely going to lead to an overdose and death.

Dr. Glatter: I want to thank you for a very informative interview. Do you have one or two pearls you’d like to give our audience as a takeaway?

Dr. Christo: I would say two things. One is, don’t give up if you have chronic pain because there is hope. We have nonopioid treatments that can be effective. Two, don’t give up if you have a substance use disorder. Talk to your primary care doctor or talk to emergency room physicians if you’re in the emergency room. The Substance Abuse and Mental Health Services Administration is a good resource, too. SAMHSA has an 800 number for support and a website. Take the opportunity to use the resources that are available.

Dr. Glatter is assistant professor of emergency medicine at Lenox Hill Hospital in New York City and at Hofstra University, Hempstead, N.Y. He is an editorial advisor and hosts the Hot Topics in EM series on Medscape. He is also a medical contributor for Forbes.

Dr. Christo is an associate professor and a pain specialist in the department of anesthesiology and critical care medicine at Johns Hopkins University, Baltimore. He also serves as director of the multidisciplinary pain fellowship program at Johns Hopkins Hospital. Christo is the author of Aches and Gains, A Comprehensive Guide to Overcoming Your Pain, and hosts an award-winning, nationally syndicated SiriusXM radio talk show on overcoming pain, called Aches and Gains.

In certain states, you don’t need a prescription to get naloxone from the pharmacy.

Dr. Glatter: I think it’s so important that it should be widely available. Certainly, the COVID-19 pandemic exacerbated the number of overdoses we saw. Are overdoses coming down or are we still at a level that’s close to 2020?

Dr. Christo: Unfortunately, we’re still seeing the same level, if not seeing it escalate. Certainly, the pandemic, because of the economic cost associated with the pandemic – loss of employment, underemployment – as well as the emotional stress of the pandemic led many people to use substances on the street in order to cope. They’re coping mechanisms, and we really haven’t seen it abate quite yet.

Dr. Glatter: Do you have a message for the lawmakers on Capitol Hill as to what we can do regarding the illegal manufacturing and distribution, how we can really crack down? Are there other approaches that we could implement that might be more tangible?

Dr. Christo: Yes. No. 1 would be to support law enforcement. No. 2 would be to create and make available more overdose prevention centers. The first was in New York City. If you look at the data on overdose prevention centers, in Canada, for example, they’ve seen a 35% reduction in overdose deaths. These are places where people who are using can go to get clean needles and clean syringes. This is where people basically oversee the use of the drug and intervene if necessary.

It seems sort of antithetical. It seems like, “Boy, why would you fund a center for people to use drugs?” The data from Canada and outside Canada are such that it can be very helpful. That would be one of my messages to lawmakers as well.
 

Vaccines to combat the synthetic opioid crisis

Dr. Glatter: Do you think that the legislators could approach some of these factories as a way to crack down, and have law enforcement be more aggressive? Is that another possible solution?

Dr. Christo: It is. Law enforcement needs to be supported by the government, by the Biden administration, so that we can prevent the influx of fentanyl and other drugs into the United States, and also to crack down on those in the United States who are manufacturing these drugs – synthetic fentanyl, first and foremost – because we’re seeing a lot of deaths related to synthetic fentanyl.

Also, we’re seeing — and this is pretty intriguing and interesting – the use of vaccines to help prevent overdose. The first human trial is underway right now for a vaccine against oxycodone. Not only that, but there are other vaccines that are in animal trials now against heroin, cocaine, or fentanyl. There’s hope there that we can use vaccines to also help reduce deaths related to overdose from fentanyl and other opioids.

Dr. Glatter: Do you think this would be given widely to the population or only to those at higher risk?

Dr. Christo: It would probably be targeting those who are at higher risk and have a history of drug abuse. I don’t think it would be something that would be given to the entire population, but it certainly could be effective, and we’re seeing encouraging results from the human trial right now.

Dr. Glatter: That’s very intriguing. That’s something that certainly could be quite helpful in the future.

One thing I did want to address is law enforcement and first responders who have been exposed to dust, or inhaled dust possibly, or had fentanyl on their skin. There has been lots of controversy. The recent literature has dispelled the controversy that people who had supposedly passed out and required Narcan after exposure to intact skin, or even compromised skin, had an overdose of fentanyl. Maybe you could speak to that and dispel that myth.

Dr. Christo: Yes, I’ve been asked this question a couple of times in the past. It’s not sufficient just to have contact with fentanyl on the skin to lead to an overdose. You really need to ingest it. That is, take it by mouth in the form of a pill, inhale it, or inject it intravenously. Skin contact is very unlikely going to lead to an overdose and death.

Dr. Glatter: I want to thank you for a very informative interview. Do you have one or two pearls you’d like to give our audience as a takeaway?

Dr. Christo: I would say two things. One is, don’t give up if you have chronic pain because there is hope. We have nonopioid treatments that can be effective. Two, don’t give up if you have a substance use disorder. Talk to your primary care doctor or talk to emergency room physicians if you’re in the emergency room. The Substance Abuse and Mental Health Services Administration is a good resource, too. SAMHSA has an 800 number for support and a website. Take the opportunity to use the resources that are available.

Robert Glatter, MD: Welcome. I’m Dr. Robert Glatter, medical advisor for Medscape Emergency Medicine. Today we have Dr. Paul Christo, a pain specialist in the Division of Pain Medicine at Johns Hopkins University School of Medicine in Baltimore, Maryland, and host of the national radio show Aches and Gains on SiriusXM Radio, joining us to discuss the ongoing and worsening fentanyl crisis in the U.S.

Welcome, Dr Christo.

Paul J. Christo, MD, MBA: Thanks so much for having me.

Dr. Glatter: I want to begin with a sobering statistic regarding overdoses. There were over 107,000 overdose deaths in the U.S. from 2020 to 2021, of which over two thirds involved the synthetic opiate fentanyl, based on recent data from the CDC.

Let’s start by having you explain how deadly fentanyl is in terms of its potency compared with morphine and heroin.

Dr. Christo: Fentanyl is considered a synthetic opioid. It’s not a naturally occurring opioid like morphine, for example, or codeine. We use this drug, fentanyl, often in the anesthesia well. We’ve used it for many years as an anesthetic for surgery very safely. In the chronic pain world, we’ve used it to help reduce chronic pain in the form of a patch.

What we’re seeing now, though, is something entirely different, which is the use of synthetic fentanyl as a mind- and mood-altering substance for those who don’t have pain, and essentially those who are buying this off the street. Fentanyl is about 80-100 times more potent than morphine, so you can put that in perspective in terms of its danger.

Dr. Glatter: Let me have you take us through an evolution of the opioid crisis from the 1990s, from long-acting opioid OxyContin, which was approved in 1995, to where we are now. There are different phases. If you could, educate our audience on how we got to where fentanyl is now the most common opiate involved in drug overdoses.

Dr. Christo: It really stems from the epidemic related to chronic pain. We have over 100 million people in the United States alone who suffer from chronic pain. Most chronic pain, sadly, is undertreated or untreated. In the ‘90s, in the quest to reduce chronic pain to a better extent, we saw more and more literature and studies related to the use of opioids for noncancer pain (e.g., for lower back pain).

There were many primary care doctors and pain specialists who started using opioids, probably for patients who didn’t really need it. I think it was done out of good conscience in the sense that they were trying to reduce pain. We have other methods of pain relief, but we needed more. At that time, in the ‘90s, we had a greater use of opioids to treat noncancer pain.

Then from that point, we transitioned to the use of heroin. Again, this isn’t among the chronic pain population, but it was the nonchronic pain population that starting using heroin. Today we see synthetic fentanyl.
 

Addressing the synthetic opioid crisis

Dr. Glatter: With fentanyl being the most common opiate we’re seeing, we’re having problems trying to save patients. We’re trying to use naloxone, but obviously in increasing amounts, and sometimes it’s not adequate and we have to intubate patients.

In terms of addressing this issue of supply, the fentanyl is coming from Mexico, China, and it’s manufactured here in the United States. How do we address this crisis? What are the steps that you would recommend we take?

Dr. Christo: I think that we need to better support law enforcement to crack down on those who are manufacturing fentanyl in the United States, and also to crack down on those who are transporting it from, say, Mexico – I think it’s primarily coming from Mexico – but from outside the United States to the United States. I feel like that’s important to do.

Two, we need to better educate those who are using these mind- and mood-altering substances. We’re seeing more and more that it’s the young-adult population, those between the ages of 13 and 25, who are starting to use these substances, and they’re very dangerous.

Dr. Glatter: Are these teens seeking out heroin and it happens to be laced with fentanyl, or are they actually seeking pure fentanyl? Are they trying to buy the colorful pills that we know about? What’s your experience in terms of the population you’re treating and what you could tell us?

Dr. Christo: I think it’s both. We’re seeing young adults who are interested in the use of fentanyl as a mind- and mood-altering substance. We’re also seeing young and older adults use other drugs, like cocaine and heroin, that are laced with fentanyl, and they don’t know it. That’s exponentially more dangerous.

Fentanyl test strips

Dr. Glatter: People are unaware that there is fentanyl in what they’re using, and it is certainly leading to overdoses and deaths. I think that parents really need to be aware of this.

Dr. Christo: Yes, for sure. I think we need better educational methods in the schools to educate that population that we’re talking about (between the ages of 13 and 25). Let them know the dangers, because I don’t think they’re aware of the danger, and how potent fentanyl is in terms of its lethality, and that you don’t need very much to take in a form of a pill or to inhale or to inject intravenously to kill yourself. That is key – education at that level – and to let those who are going to use these substances (specifically, synthetic fentanyl) know that they should consider the use of fentanyl test strips.

Fentanyl test strips would be primarily used for those who are thinking that they’re using heroin but there may be fentanyl in there, or methamphetamine and there may be fentanyl, and they don’t know. The test strip gives them that knowledge.

The other harm reduction strategies would be the use of naloxone, known as Narcan. That’s a lifesaver. You just have to spritz it into the nostril. You don’t do it yourself if you’re using the substance, but you’ve got others who can do it for you. No question, that’s a lifesaver. We need to make sure that there’s greater availability of that throughout the entire country, and we’re seeing some of that in certain states. In certain states, you don’t need a prescription to get naloxone from the pharmacy.

Dr. Glatter: I think it’s so important that it should be widely available. Certainly, the COVID-19 pandemic exacerbated the number of overdoses we saw. Are overdoses coming down or are we still at a level that’s close to 2020?

Prompt diagnosis of idiopathic pulmonary fibrosis is essential to reduce mortality, and improving education of primary care providers can help, suggests a new white paper.

The nonspecific nature of the symptoms of idiopathic pulmonary fibrosis (IPF) especially in early stages, and the relative rarity of IPF compared with other conditions that have similar symptoms, may contribute to a delay in diagnosis in the primary care setting, wrote Daniel F. Dilling, MD, of Loyola University Chicago, Maywood, Ill., and colleagues in Chest: Clinical Perspectives (Dilling et al. State of Practice: Factors Driving Diagnostic Delays in Idiopathic Pulmonary Fibrosis. Chest. 2022).

“We have learned over and over again through research, and also through talking with our own patients with IPF, that there is often a long lag between the first signs of the disease and a diagnosis of IPF,” corresponding author Dr. Dilling said in an interview.

“Even some pulmonary specialists can be uncertain about how to approach the diagnosis when a CT scan or other test first suggests the possibility; this can cost a patient precious time, as being on drug therapy earlier can result in preservation of lung function,” he said. “By sounding the alarm bell with this paper, we hope to promote awareness and education/training within the primary care community as well as the pulmonary community, and also to make all of them aware of the possibility of referral to specialty ILD [interstitial lung disease] centers when desired and possible,” he added.  

The researchers conducted a pair of online surveys to inform the development of improving education on IPF among primary care providers.

In the white paper, which can be accessed online, the authors reported results of the surveys. One included 100 general pulmonologists and the other included 306 primary care physicians (156 practiced family physicians and 150 practiced general internal medicine). The data were collected between April 11, 2022, and May 16, 2022. Participants were asked to respond to a patient case scenario of a 55-year-old woman with nonspecific symptoms such as shortness of breath on moderate exertion, cough, exhaustion, and trouble sleeping.

The PCPs were most likely to evaluate the patient for a cardiac condition (46%), 25% would evaluate for chronic obstructive pulmonary disease (COPD), and 23% for asthma. More than half (58%) ranked progressive fibrosing ILD as one of their bottom two diagnoses.

A total of 87% of PCPs said they would begin a diagnostic workup to evaluate symptoms if the patient had no preexisting respiratory disease, compared with 61% for patients with a respiratory diagnosis.

Although 93% of PCPs cited a chest x-ray as part of the initial patient workup, fewer than half said they would order an echocardiogram, spirometry, or pulmonary function test (PFT), and 11% said they would include diffusion capacity testing in the initial workup.

In addition, PCPs were less likely to ask patients about issues that might prompt an IPF diagnosis, such as exposures to agents through work, hobbies, the environment, or comorbidities.

In the pulmonology survey, more than 75% of respondents cited patient history, high-resolution tomography scan, serologic testing, and review for autoimmune disease symptoms as first steps in a diagnostic response to patients with suspected IPF.
 

Differences between PCPs’ and pulmonolgists’ responses

Both PCPs and pulmonologists responded to several questions to assess knowledge and opinion gaps related to IPF. Overall, pulmonologists were more likely than PCPs to cite both imaging and testing issues and waiting 6-8 weeks after symptom onset before imaging as contributing factors to diagnostic delays.

PCPs more often expressed beliefs that delayed diagnosis had little impact on a patient with IPF, and that the treatments may be worse than the disease.

Dr. Dilling said he was not surprised by the survey findings, as similar clues about the underdiagnosis of IPF have surfaced in prior studies.

“We need to get the word out to primary care physicians, to pulmonary physicians, and even to the public, that idiopathic pulmonary fibrosis and other forms of interstitial lung disease are out there and prevalent, and that making the right diagnosis in a timely way can lead to better outcomes for patients,” he said.

The take-home message for primary care is to think outside the COPD box, said Dr. Dilling. “Just because someone has shortness of breath or cough and used to smoke does not automatically mean that they have COPD,” he emphasized. “Listen carefully for crackles (rales) on exam. Get spirometry or PFTs before you secure the diagnosis of COPD, or else you will be missing all of your cases of pulmonary fibrosis; think of pulmonary fibrosis and use imaging to help guide your diagnosis,” he said.

The authors suggested several education goals for PCPs, including establishing the importance of early evaluation, outlining the correct approach to a patient workup, encouraging prompt referral, and empowering PCPs as part of the team approach to IPF patients’ care. For pulmonologists, only 11% of those surveyed said they were aware of the latest developments in antifibrotic research, and education efforts might include information about drug pipelines and clinical trials, as well as technology.

Looking ahead, “We need to better understand how to find the pulmonary fibrosis in the community,” Dr. Dilling said. This understanding may come in part from greater education and awareness, he noted. However, eventually there may be ways to enhance the reading of PFTs and of CT scans through artificial intelligence technologies that would not only prompt clinicians to recognize what they are seeing, but would prompt them to refer and send the patient on the correct diagnostic path as soon as possible, he added.
 

Key message: Include ILD in differential diagnosis of patients with shortness of breath and/or cough

Advances in diagnostics and therapies for interstitial lung disease can take time to be absorbed and adopted, and patients with ILD and pulmonologists caring for ILD, specifically IPF, continue to report delays in diagnosis and therapy, said Krishna Thavarajah, MD, a pulmonologist at Henry Ford Hospital, Detroit, Mich., in an interview.

The current study findings of the time to diagnosis and the approach to patient workups echo her own clinical experience, Dr. Thavarajah said. “There is a delay in IPF diagnosis as physicians look to more common diagnoses, such as cardiac disease or chronic obstructive pulmonary disease, prior to pursuit of additional workup, and the attitude toward treatment has, in some ways, lagged behind advances in therapy, including timing and feasibility of therapy for IPF,” she said.

The key message for primary care physicians is to include ILD in the differential diagnosis of patients with shortness of breath and/or cough, especially if the initial cardiac and pulmonary test (meaning at least a chest x-ray and pulmonary function tests, including a diffusion capacity) are not pointing to an alternative cause within 3 months of presentation, Dr. Thavarajah said.

Once IPF is diagnosed, primary care clinicians should know that there are FDA-approved therapies that improve survival, said Dr. Thavarajah. “There are identifiable and treatable comorbid conditions,” she added. “The statement of ‘time lost is lung lost’ sums up the care of an IPF patient; partnerships between primary care clinicians, pulmonologists, and referral centers can provide the patient multiple levels of support with quality-of-life interventions, treatments, and also clinical trials, delivered by a team of providers,” she said. 
In the wake of the current study, more research is needed with outcome studies regarding educational interventions targeting primary care and pulmonologists on appropriate workup, timing of workup, and current therapy for IPF patients, she added.

The white paper received no outside funding. The authors and Dr. Thavarajah had no financial conflicts to disclose.

Although 93% of PCPs cited a chest x-ray as part of the initial patient workup, fewer than half said they would order an echocardiogram, spirometry, or pulmonary function test (PFT), and 11% said they would include diffusion capacity testing in the initial workup.

In addition, PCPs were less likely to ask patients about issues that might prompt an IPF diagnosis, such as exposures to agents through work, hobbies, the environment, or comorbidities.

In the pulmonology survey, more than 75% of respondents cited patient history, high-resolution tomography scan, serologic testing, and review for autoimmune disease symptoms as first steps in a diagnostic response to patients with suspected IPF.
 

Differences between PCPs’ and pulmonolgists’ responses

Both PCPs and pulmonologists responded to several questions to assess knowledge and opinion gaps related to IPF. Overall, pulmonologists were more likely than PCPs to cite both imaging and testing issues and waiting 6-8 weeks after symptom onset before imaging as contributing factors to diagnostic delays.

PCPs more often expressed beliefs that delayed diagnosis had little impact on a patient with IPF, and that the treatments may be worse than the disease.

Dr. Dilling said he was not surprised by the survey findings, as similar clues about the underdiagnosis of IPF have surfaced in prior studies.

“We need to get the word out to primary care physicians, to pulmonary physicians, and even to the public, that idiopathic pulmonary fibrosis and other forms of interstitial lung disease are out there and prevalent, and that making the right diagnosis in a timely way can lead to better outcomes for patients,” he said.

The take-home message for primary care is to think outside the COPD box, said Dr. Dilling. “Just because someone has shortness of breath or cough and used to smoke does not automatically mean that they have COPD,” he emphasized. “Listen carefully for crackles (rales) on exam. Get spirometry or PFTs before you secure the diagnosis of COPD, or else you will be missing all of your cases of pulmonary fibrosis; think of pulmonary fibrosis and use imaging to help guide your diagnosis,” he said.

The authors suggested several education goals for PCPs, including establishing the importance of early evaluation, outlining the correct approach to a patient workup, encouraging prompt referral, and empowering PCPs as part of the team approach to IPF patients’ care. For pulmonologists, only 11% of those surveyed said they were aware of the latest developments in antifibrotic research, and education efforts might include information about drug pipelines and clinical trials, as well as technology.

Looking ahead, “We need to better understand how to find the pulmonary fibrosis in the community,” Dr. Dilling said. This understanding may come in part from greater education and awareness, he noted. However, eventually there may be ways to enhance the reading of PFTs and of CT scans through artificial intelligence technologies that would not only prompt clinicians to recognize what they are seeing, but would prompt them to refer and send the patient on the correct diagnostic path as soon as possible, he added.
 

Key message: Include ILD in differential diagnosis of patients with shortness of breath and/or cough

Advances in diagnostics and therapies for interstitial lung disease can take time to be absorbed and adopted, and patients with ILD and pulmonologists caring for ILD, specifically IPF, continue to report delays in diagnosis and therapy, said Krishna Thavarajah, MD, a pulmonologist at Henry Ford Hospital, Detroit, Mich., in an interview.

The current study findings of the time to diagnosis and the approach to patient workups echo her own clinical experience, Dr. Thavarajah said. “There is a delay in IPF diagnosis as physicians look to more common diagnoses, such as cardiac disease or chronic obstructive pulmonary disease, prior to pursuit of additional workup, and the attitude toward treatment has, in some ways, lagged behind advances in therapy, including timing and feasibility of therapy for IPF,” she said.

The key message for primary care physicians is to include ILD in the differential diagnosis of patients with shortness of breath and/or cough, especially if the initial cardiac and pulmonary test (meaning at least a chest x-ray and pulmonary function tests, including a diffusion capacity) are not pointing to an alternative cause within 3 months of presentation, Dr. Thavarajah said.

Once IPF is diagnosed, primary care clinicians should know that there are FDA-approved therapies that improve survival, said Dr. Thavarajah. “There are identifiable and treatable comorbid conditions,” she added. “The statement of ‘time lost is lung lost’ sums up the care of an IPF patient; partnerships between primary care clinicians, pulmonologists, and referral centers can provide the patient multiple levels of support with quality-of-life interventions, treatments, and also clinical trials, delivered by a team of providers,” she said. 
In the wake of the current study, more research is needed with outcome studies regarding educational interventions targeting primary care and pulmonologists on appropriate workup, timing of workup, and current therapy for IPF patients, she added.
