Use the stool! Fecal microbiota transplants help kids with diarrheal infection
(AAP).
However, fecal microbiota transplants (FMTs) should not be used to treat other gastrointestinal ailments such as Crohn’s disease or ulcerative colitis, because scientific evidence falls short on effectiveness in treating these conditions, the group said.
C. difficile infections (CDIs) are major contributors to hospital-associated diarrhea and diarrhea caused by antibiotics. An FMT involves introducing the feces of a healthy person into the gastrointestinal tract, usually through a nasogastric tube but sometimes in capsules containing healthy stool. Serious adverse reactions associated with an FMT, such as hospitalization, are rare, occuring in roughly 2% of case, the AAP said.
An FMT “does have a place for treatment of recurrent CDIs in children,” said Maria Oliva-Hemker, MD, a pediatric gastroenterologist at Johns Hopkins University School of Medicine in Baltimore and the lead author of the report, which was online in Pediatrics.
The AAP strongly encourages people not to perform an FMT at home, although caregivers may be tempted due to a lack of medical facilities located nearby to deliver this care.
“People might see a video on YouTube and think they can do this themselves,” Dr. Oliva-Hemker said.
An FMT requires screening of donors for any infections, which involves administering questionnaires and analyzing donor blood and stool, which are tasks better suited for medical facilities than for a living room.
No controlled or prospective clinical trials on the efficacy of FMT for children exist, according to the AAP. But a retrospective study published in 2020 showed that one or two courses of FMT prevented CDI recurrence in children 87% of the time. Researchers defined the eradication of CDIs as no recurrence for at least 2 months after an FMT and noted the success rates in children were comaparable to those reported in adults.
Unlike pediatric data, adult data come from a randomized clinical trial.
“Sometimes, kids are the last people to be enrolled in these trials,” said Maribeth Nicholson, MD, MPH, a pediatric gastroenterologist at Vanderbilt University Medical Center in Nashville, Tenn., an author of the 2020 study.
Dr. Nicholson, who was not involved in the AAP report, said that the retrospective data are strong enough to justify using FMT to eradicate CDIs in children. But researchers are unclear about the biologic mechanisms that make FMTs work.
Dr. Nicholson said that many therapeutics meant to produce a healthier microbiome are being studied in clinical trials. Any clinical trials of such products should include children, Dr. Nicholson said. A child’s gastrointestinal microbiome is actively developing, Dr. Nicholson added, compared with the relatively stable microbiome of an adult.
“When we think about the microbiome it makes sense to target kids, because they’re more apt to respond to these therapies. I worry that somebody will say ‘this doesn’t work in adults,’ and it just stops there,” Dr. Nicholson said.
Though the AAP said that the benefits of FMT for treating CDIs are clear, the data available for treating other conditions such as ulcerative colitis or Crohn’s disease are less convincing. Any child receiving an FMT for these ailments should only do so as part of a clinical trial, the group said.
The AAP report endorses a joint position paper, published in 2019, about the benefits of FMTs for CDIs from North American and European pediatric gastroenterology societies. Dr. Nicholson was an author of this joint statement and hopes that the AAP report raises further awareness among pediatricians that FMTs are a safe and effective treatment for recurrent CDIs.
“This is something that maybe is not as discussed in pediatric circles. Kids need FMTs sometimes,” Dr. Nicholson said.
Dr. Oliva-Hemker and Dr. Nicholson report no relevant financial relationships.

Lebrikizumab gets European nod for treating moderate-to-severe atopic dermatitis
The , according to a press release from the manufacturer.
Lebrikizumab, which selectively targets interleukin-13 and inhibits its signaling pathway, will first be available in Germany, with a rollout in other European countries expected through 2024, according to Almirall, the manufacturer.
The European approval of lebrikizumab (Ebglyss) was based on data from a trio of pivotal phase 3 studies including ADvocate1 and ADvocate2, which evaluated lebrikizumab as monotherapy, and ADhere, which evaluated lebrikizumab in combination with topical corticosteroids. All three trials included adult and adolescent patients aged 12 years and older with moderate-to-severe AD.
In the two ADvocate studies, published in the New England Journal of Medicine, participants were randomized to a 250-mg injection of lebrikizumab or placebo every 2 weeks. The primary outcome was a score of clear or almost clear skin based on the Investigator’s Global Assessment with at least a 2-point reduction from baseline to 16 weeks.
Compared with placebo, lebrikizumab showed significant clinical efficacy in both studies. In study 1, 43.1% of 283 patients treated with lebrikizumab versus 12.7% of 141 patients on placebo met the primary endpoint (P < .001), as did 33.2% of the 281 patients on lebrikizumab and 10.8% of 146 patients on placebo in study 2 (P < .001). In addition, 58.8% and 52.1% of patients on lebrikizumab in studies 1 and 2, respectively, met the secondary endpoint of a 75% reduction in the Eczema Area and Severity Index score (EASI-75), versus 16.2% and 18.1% of patients on placebo in study 1 and 2, respectively (P < .001 for both).
In the ADhere study, published in JAMA Dermatology, 41.2% of patients receiving a lebrikizumab/corticosteroid combination and 22.1% of those randomized to a placebo/corticosteroid combination met the primary endpoint of IGA scores of 0 or 1 at 16 weeks, and nearly 70% patients treated with a combination of lebrikizumab and topical corticosteroids achieved EASI-75, compared with 42% of those on the combination.
Nearly 80% of patients who responded at 16 weeks and continued treatment with lebrikizumab as monotherapy or combination therapy showed sustained results up to 52 weeks with maintenance monthly dosing, according to the Almirall press release.
Most adverse events across the studies were mild or moderate and were not associated with treatment discontinuation. The most common adverse reactions were conjunctivitis, injection site reactions, allergic conjunctivitis, and dry eye.
Further research has shown showed clinical efficacy and safety in patients who used lebrikizumab for up to 2 years, either as monotherapy or in combination with topical corticosteroids, according to the manufacturer.
Lebrikizumab remains under review in the United States after the Food and Drug Administration issued a complete response letter in October regarding findings made during an inspection of a third-party contract manufacturer that included the “monoclonal antibody drug substance” for lebrikizumab, although no concerns about clinical data or safety were raised, Eli Lilly announced in October. Eli Lilly has the rights to develop lebrikizumab in the United States and the rest of the world excluding Europe.

Sepsis mortality greater in Black than White children despite similar interventions
WASHINGTON – , according to research presented at the annual meeting of the American Academy of Pediatrics.
The only other difference between Black and White pediatric patients was the length of hospital stay and the length of time in the ICU among those who died. In both cases, Black children who died spent more time in the hospital and in the ICU, reported Michael H. Stroud, MD, a pediatric critical care physician at the University of Arkansas for Medical Sciences in Little Rock, and his colleagues.
“Further investigations are needed to identify biases, conscious and unconscious, potential socioeconomic factors, and genetic predispositions leading to racial disparities in outcomes of children with pediatric sepsis, severe sepsis, and septic shock,” Dr Stroud and his colleagues said.
Nathan T. Chomilo, MD, adjunct assistant professor of pediatrics at the University of Minnesota, Minneapolis, who was not involved in the study but reviewed it, said the research “builds upon existing evidence that our health care system has work to do to meet its goal of treating patients equitably and provide everyone the opportunity for health.” He found the racial disparity in death particularly striking in 2023. “In the U.S., with all our wealth, knowledge, and resources, very few children should die from this, let alone there be such a stark gap,” Dr. Chomilo wrote.
Racial disparities persist
Dr. Stroud noted that many institutions currently use “automated, real-time, algorithm-based detection of sepsis, severe sepsis, and septic shock incorporated into the electronic medical record,” which leads to earlier recognition and resuscitation and overall better outcomes. Yet racial disparities in sepsis mortality rates persist, and he and his colleagues wanted to explore whether they remained even with these EMR-incorporated systems.
The researchers analyzed data from all patients at Arkansas Children’s Hospital who had sepsis, severe sepsis, or septic shock between January 2018 and April 2022. The hospital uses a best practice advisory (BPA) in the EMR whose activation leads to a bedside huddle and clinical interventions. For this study, the researchers defined a sepsis episode as either a BPA activation or an EMR diagnosis of sepsis, severe sepsis, or septic shock.
Among the 3,514 patients who had a sepsis episode during the study, 60.5% were White (n = 2,126) and 20.9% were Black (n = 736). Overall mortality was 1.65%, but that included 3.13% of Black children versus 1.27% of White children (odds ratio [OR] 2.51, P = .001). No significant differences in mortality were seen in gender or age.
Clinical interventions in the two groups were also similar: Total IV antibiotic days were 23.8 days for Black children and 21.6 days for White children (P = .38); total vasoactive infusion days were 2.2 for Black children and 2.6 for White (P = .18); and extracorporeal membrane oxygenation was necessary for 26.1% of Black children and 18.5% of White children (P = .52).
Length of hospitalization stay, however, was an average 4 days longer for Black children (16.7 days) versus White children (12.7 days) who died (P = .03). ICU stay for Black children who died was also an average 1.9 days longer (7.57 vs. 5.7 days; P = .01). There were no significant differences in the EMR between Black and White patients, however, in the percent who were over the threshold for antibiotic administration and the percent who received an IV fluid bolus.
Contributing factors
Dr. Chomilo said that most BPA systems require staff – including rooming and triage staff, nurses. and physicians – to enter vital signs, order labs, enter the results into the system, and enter other data used by the algorithm. “So even though the time from when those BPA warnings flagged to when clinical interventions were documented didn’t show a significant difference, there are numerous other points along a child’s illness that may be contributing to these numbers,” Dr. Chomilo said.
For example, he pointed out that differences in health insurance coverage could have influenced whether their parent or caregiver was able to bring them in early enough to be diagnosed since studies have revealed disparate access to regular care due to structural racism in the health care system. Studies have also shown disparate rates of patients being triaged or having to wait longer in emergency departments, he added.
“When the child was brought in, how were they triaged? How long did they wait before they had vitals taken? How long until they were seen by a clinician?” Dr. Chomilo said. “Was their care on the inpatient ward the same or different? What was the source of sepsis? Was it all infectious or other issues [since] cancer and autoimmune illnesses can also trigger a sepsis evaluation, for example? Overall, I suspect answers to several of these questions would reveal a disparity due to structural racism that contributed to the ultimate disparity in deaths.”
Other social determinants of health that could have played a role in the outcome disparities here might include the family’s access to transportation options, parental employment or child care options, and nutrition access since baseline nutritional status can be a factor in the outcomes of severe illnesses like sepsis.
”I don’t think this study provided enough information about the potential causative factors to come to any strong conclusions,” Dr. Chomilo said. But it’s important for clinicians to be aware of how biases in the health care system put Black, Indigenous and other communities at higher risk for worse clinical outcomes.
“I would reiterate that clinicians in the hospital can help improve outcomes by being aware of structural racism and structural inequity and how that may contribute to their patient’s risk of severe illness as the decide how to approach their treatment and engaging the patient’s family,” Dr. Chomilo said. “We cannot rely solely on universal tools that don’t take this into account when we are looking to improve clinical outcomes for everyone. Otherwise we will see these gaps persist.”

Among the 3,514 patients who had a sepsis episode during the study, 60.5% were White (n = 2,126) and 20.9% were Black (n = 736). Overall mortality was 1.65%, but that included 3.13% of Black children versus 1.27% of White children (odds ratio [OR] 2.51, P = .001). No significant differences in mortality were seen in gender or age.
Clinical interventions in the two groups were also similar: Total IV antibiotic days were 23.8 days for Black children and 21.6 days for White children (P = .38); total vasoactive infusion days were 2.2 for Black children and 2.6 for White (P = .18); and extracorporeal membrane oxygenation was necessary for 26.1% of Black children and 18.5% of White children (P = .52).
Length of hospitalization stay, however, was an average 4 days longer for Black children (16.7 days) versus White children (12.7 days) who died (P = .03). ICU stay for Black children who died was also an average 1.9 days longer (7.57 vs. 5.7 days; P = .01). There were no significant differences in the EMR between Black and White patients, however, in the percent who were over the threshold for antibiotic administration and the percent who received an IV fluid bolus.
Contributing factors
Dr. Chomilo said that most BPA systems require staff – including rooming and triage staff, nurses. and physicians – to enter vital signs, order labs, enter the results into the system, and enter other data used by the algorithm. “So even though the time from when those BPA warnings flagged to when clinical interventions were documented didn’t show a significant difference, there are numerous other points along a child’s illness that may be contributing to these numbers,” Dr. Chomilo said.
For example, he pointed out that differences in health insurance coverage could have influenced whether their parent or caregiver was able to bring them in early enough to be diagnosed since studies have revealed disparate access to regular care due to structural racism in the health care system. Studies have also shown disparate rates of patients being triaged or having to wait longer in emergency departments, he added.
“When the child was brought in, how were they triaged? How long did they wait before they had vitals taken? How long until they were seen by a clinician?” Dr. Chomilo said. “Was their care on the inpatient ward the same or different? What was the source of sepsis? Was it all infectious or other issues [since] cancer and autoimmune illnesses can also trigger a sepsis evaluation, for example? Overall, I suspect answers to several of these questions would reveal a disparity due to structural racism that contributed to the ultimate disparity in deaths.”
Other social determinants of health that could have played a role in the outcome disparities here might include the family’s access to transportation options, parental employment or child care options, and nutrition access since baseline nutritional status can be a factor in the outcomes of severe illnesses like sepsis.
”I don’t think this study provided enough information about the potential causative factors to come to any strong conclusions,” Dr. Chomilo said. But it’s important for clinicians to be aware of how biases in the health care system put Black, Indigenous and other communities at higher risk for worse clinical outcomes.
“I would reiterate that clinicians in the hospital can help improve outcomes by being aware of structural racism and structural inequity and how that may contribute to their patient’s risk of severe illness as the decide how to approach their treatment and engaging the patient’s family,” Dr. Chomilo said. “We cannot rely solely on universal tools that don’t take this into account when we are looking to improve clinical outcomes for everyone. Otherwise we will see these gaps persist.”

Study confirms small blood cancer risk from CT scans
The findings, published online in Nature Medicine, are based on more than 1.3 million CT scans in nearly 900,000 people younger than 22 years old when scanned.
This study makes a “significant contribution to the understanding of the effects of ionizing radiation, specifically x-rays, on the human body at the levels of radiation exposure encountered in diagnostic CT procedures,” Peter Marsden, PhD, and Jim Thurston, radiation protection experts at Dorset County (England) Hospital, NHS Foundation Trust, said in a press release from the U.K. nonprofit Science Media Centre.
These findings highlight levels of risk that “align with those currently estimated and do not suggest that the use of CT carries a greater risk than previously thought,” Dr. Marsden and Thurston said.
Exposure to moderate- (≥ 100 mGy) to high-dose (≥ 1 Gy) ionizing radiation is a well-established risk factor for leukemia in both children and adults. However, the risk associated with low-dose exposure (< 100 mGy) typically associated with diagnostic CT exams in children and teens remains unclear.
The current study, coordinated by the International Agency for Research on Cancer, aimed to improve direct estimates of cancer risk from low-dose radiation exposure from CT scans performed in childhood and adolescence. The researchers estimated radiation doses to the active bone marrow based on body part scanned, patient characteristics, time period, and inferred CT technical parameters.
A total of 790 hematologic malignancies, including lymphoid and myeloid malignancies, were identified during follow-up. More than half (51%) of the cases were diagnosed in people under age 20 and 88.5% were diagnosed in people under age 30 years.
Overall, the observational study found a nearly twofold excess risk of all hematologic malignancies per 100 mGy in children, adolescents, and young adults, with similar risk estimates observed for lymphoid and myeloid cancers. The excess relative risk for hematologic malignancies increased as the number of CT exams increased – with risk rising by 43% per exam.
The results of this study “strengthen the findings from previous low-dose studies of a consistent and robust dose-related increased risk of radiation-induced hematological malignancies” and highlight the importance of optimizing doses in this patient population, study author Elisabeth Cardis, PhD, with the Barcelona Institute for Global Health, and colleagues concluded.
Sarah McQuaid, PhD, chair of the nuclear medicine special interest group, Institute of Physics and Engineering in Medicine, York, England, agreed.
“This publication indicates that there could be a small cancer risk from CT scans in young people, but it is important for this to be viewed in the context of the substantial benefit these scans bring, due to the important diagnostic information they provide,” Dr. McQuaid said in the press release. Overall, “the number of patients whose medical care will have been improved from these CT scans will have been very high, and lives undoubtedly saved as a result.”
The study had no commercial funding. The authors and outside experts reported no relevant financial relationships.

AI tool perfect in study of inflammatory diseases
Artificial intelligence can distinguish overlapping inflammatory conditions with total accuracy, according to a new study presented at the annual meeting of the American College of Rheumatology.
Texas pediatricians faced a conundrum during the pandemic. Endemic typhus, a flea-borne tropical infection common to the region, is nearly indistinguishable from multisystem inflammatory syndrome in children (MIS-C), a rare condition set in motion by SARS-CoV-2 infection. Children with either ailment had seemingly identical symptoms: fever, rash, gastrointestinal issues, and in need of swift treatment. A diagnosis of endemic typhus can take 4-6 days to confirm.
Tiphanie Vogel, MD, PhD, a pediatric rheumatologist at Texas Children’s Hospital, Houston, and colleagues sought to create a tool to hasten diagnosis and, ideally, treatment. To do so, they incorporated machine learning and clinical factors available within the first 6 hours of the onset of symptoms.
The team analyzed 49 demographic, clinical, and laboratory measures from the medical records of 133 children with MIS-C and 87 with endemic typhus. Using deep learning, they narrowed the model to 30 essential features that became the backbone of AI-MET, a two-phase clinical-decision support system.
Phase 1 uses 17 clinical factors and can be performed on paper. If a patient’s score in phase 1 is not determinative, clinicians proceed to phase 2, which uses an additional 13 weighted factors and machine learning.
In testing, the two-part tool classified each of the 220 test patients perfectly. And it diagnosed a second group of 111 patients with MIS-C with 99% (110/111) accuracy.
Of note, “that first step classifies [a patient] correctly half of the time,” Dr. Vogel said, so the second, AI phase of the tool was necessary for only half of cases. Dr. Vogel said that’s a good sign; it means that the tool is useful in settings where AI may not always be feasible, like in a busy ED.
Melissa Mizesko, MD, a pediatric rheumatologist at Driscoll Children’s Hospital in Corpus Christi, Tex., said that the new tool could help clinicians streamline care. When cases of MIS-C peaked in Texas, clinicians often would start sick children on doxycycline and treat for MIS-C at the same time, then wait to see whether the antibiotic brought the fever down.
“This [new tool] is helpful if you live in a part of the country that has typhus,” said Jane Burns, MD, director of the Kawasaki Disease Research Center at the University of California, San Diego, who helped develop a similar AI-based tool to distinguish MIS-C from Kawasaki disease. But she encouraged the researchers to expand their testing to include other conditions. Although the AI model Dr. Vogel’s group developed can pinpoint MIS-C or endemic typhus, what if a child has neither condition? “It’s not often you’re dealing with a diagnosis between just two specific diseases,” Dr. Burns said.
Dr. Vogel is also interested in making AI-MET more efficient. “This go-round we prioritized perfect accuracy,” she said. But 30 clinical factors, with 17 of them recorded and calculated by hand, is a lot. “Could we still get this to be very accurate, maybe not perfect, with less inputs?”
In addition to refining AI-MET, which Texas Children’s eventually hopes to make available to other institutions, Dr. Vogel and associates are also considering other use cases for AI. Lupus is one option. “Maybe with machine learning we could identify clues at diagnosis that would help recommend targeted treatment,” she said
Dr. Vogel disclosed potential conflicts of interest with Moderna, Novartis, Pfizer, and SOBI. Dr. Burns and Dr. Mizesko disclosed no relevant conflicts of interest.

CDC says child vaccination exemptions hit all-time high
– the highest exemption rate ever reported in the United States.
Of the 3% of children who got exemptions, 0.2% were for medical reasons and 2.8% for nonmedical reasons, the CDC report said. The overall exemption rate was 2.6% for the previous school year.
Though more children received exemptions, the overall national vaccination rate remained steady at 93% for children entering kindergarten for the 2022-2023 school year. Before the COVID-19 pandemic, the overall rate was 95%, the CDC said.
“The bad news is that it’s gone down since the pandemic and still hasn’t rebounded,” Sean O’Leary, MD, a University of Colorado pediatric infectious diseases specialist, told The Associated Press. “The good news is that the vast majority of parents are still vaccinating their kids according to the recommended schedule.”
The CDC report did not offer a specific reason for higher vaccine exemptions. But it did note that the increase could be caused by the COVID-19 pandemic and COVID vaccine hesitancy.
“There is a rising distrust in the health care system,” Amna Husain, MD, a pediatrician in private practice in North Carolina and a spokesperson for the American Academy of Pediatrics, told NBC News. Vaccine exemptions “have unfortunately trended upward with it.”
Exemption rates varied across the nation. The CDC said 40 states reported a rise in exemptions and that the exemption rate went over 5% in 10 states: Alaska, Arizona, Hawaii, Idaho, Michigan, Nevada, North Dakota, Oregon, Utah, and Wisconsin. Idaho had the highest exemption rate in 2022 with 12%.
While requirements vary from state to state, most states require students entering kindergarten to receive four vaccines: MMR, DTaP, polio, and chickenpox.

Mental health characteristics of refugee children
Since 1983, when I was a child and fled as a boat refugee from Vietnam with my mother, the international plight of displaced people has only worsened. From 1997 to 2022, the number of forcibly displaced people has more than tripled, growing from 34 million to more than 108 million.1
Displaced people are designated as refugees only when they cross international borders and meet the United Nations High Commissioner for Refugees’ (UNHCR) definition as “persons outside their countries of origin who are in need of international protection because of a serious threat to their life, physical integrity, or freedom in their country of origin as a result of persecution, armed conflict, violence, or serious public disorder.”2 There is a separate mandate by the United Nations for the aid of Palestinian refugees under the United Nations General Assembly’s United Nations Relief and Works Agency for Palestinian Refugees in the Near East (UNRWA).3 Of the displaced in 2022, more than 36 million were recognized as refugees under UNHCR and UNRWA mandates.1 Of these, almost 50% were children, at 17.5 million.4 To make matters worse, worldwide children represent less than one-third of the population.4 Since 2022, the increase in refugeeism is mostly driven by Ukraine and Syria, though also significantly Afghanistan, Venezuela, Sudan, Myanmar, Congo, Somalia, and Central African Republic.4 Refugeeism is a growing problem that disproportionately impacts children through sheer number, and one suspects, given their greater overall vulnerabilities compared with adults, physical and mental health consequences.
Traumas of refugees compared with non-refugee immigrants
In terms of mental health, refugees are distinct from non-refugee immigrants in that they likely experience more severe psychosocial adversities from greater poverty, greater risk of family separation, and uncertainty of the asylum process.5-8
From my own experience, this stems from the urgent nature of the refugee’s displacement, where they are often fleeing an immediate danger. My family had fled persecution from Communist forces and the social economic collapse that rendered Vietnam, for a time, one of the poorest in the world.9 Or, as my mother observed, “We had to leave because even doctors were starving.”
Refugees often have little preparation, have little legal protection since they are often criminalized, and are forced to endure dangerous conditions where they are vulnerable to smugglers and criminals who exploit their unprotected status. Once they arrive in their new country, they often do not have other family as social supports or resources. They themselves become the anchor for future legal and orderly immigration of their remaining family, given that they can extend their refugee status to those left behind.10 These non-refugee immigrants, unlike their refugee counterparts, are often flown to their new homes with more preparation, protecting them from dangerous conditions, and have the benefit of family who provide them with resources. As such, refugees tend to experience more traumatic life events than non-refugee immigrants. This was true in my family where those of us who initially escaped became the anchors to legally, and more safely, immigrate most of our family in Vietnam. We became their resources, likely making their acclimation smoother.
The mental health of refugee children and their caregivers
It is important to understand the stressors affecting the caregivers of children, since effective treatment of their mental health conditions can also benefit the children as well.11 In fact, among the greatest protective factors for refugee children is the presence of an adult caregiver, suggesting that the child’s mental health is dependent on the caregivers.
Those children who are separated show much worse mental health sequalae.12 As such, an understanding of the caregiver’s stressors is important. For example, when we were escaping Vietnam, my mom would protect me from our hardships by talking about our goals in America, minimizing our dangers by saying that we would be rewarded with things like a hamburger with its seemingly impossible amount of meat. Physically, my mother would always sleep with her arms around me and a knife hidden in order to ward off any attackers at night. When I was starving in the hull of a boat, having not eaten for days, my mother begged for food and gave me what she could get. And post-escape, my family focused on work and applied for aid for shelter and food, while encouraging us to invest in education, likely preventing involvement in criminal activities or gangs. Though overall, my family shielded me from the worst consequences, they also passed on their fears. One of my uncles had been killed by the police when he tried to escape, and so my family passed down a deep suspicion of authorities, whether they were the police or school principals. My mother had vivid memories of Communist re-education camps, which likely gave her a lasting fear that a Communist would find out our identities in America and re-capture us.
The mental health risk of refugees
Given that refugees tend to experience greater amounts of traumatic life events and a vast array of stressors sustained across years and even decades before, during, and after migration, it is no wonder they have much higher rates of mental health conditions, most predominantly PTSD and affective disorders.13,14 They are at particular risk of developing psychoses because they are more likely to experience a range of physical, psychological, and psychosocial problems associated with adversities such as violence, discrimination, economic stress, and social isolation.13 For example, the period leading up to my escape consisted of decades of prolonged war: the French-Indochina from 1945 to 1954, then the Vietnam War from 1955 to 1975) as well as the persecution and re-education camps afterward. What my family had to endure created a period of fear and loss into which I was born into in 1976. That year, my family had lost its fortune due to the Communist government seizing of our home and business, plunging us from a comfortable middle- to upper-class life to poverty. There was also widespread fear of systematic rape by the Communist victors. So my family endured great stress and the loss of a way of life leading up to our escape.
For the refugees, the escape itself is often a dangerous journey where, given its emergent nature, they are often exposed to the elements. We know about the current situation in Ukraine and Gaza, where children are fleeing from bombs and bullets. In my situation, we endured weeks of starvation crammed in the hull of boat as we forged through the Indian Ocean to the Philippines. One of my aunts, on a separate trip, perished because her boat had capsized, like so many others. Though impossible to verify, it has been estimated that up to 70% of Vietnamese refugees died during their escape.15 After the boat, my mother and I still had to brave Malaysian jungles and prisons, and then refugee camps for a year before we reached safety at an American Embassy in the Philippines. After we gained sponsorship to America, the traumas did not abate, but were only replaced by those of culture shock, poverty, and alienation. Taken by themselves, significant traumas exist in each phase of a refugee child’s escape, whether before, during, or after. These traumas are likely compounded since they are continuously layered and sustained across years, even decades. They affect not only the children, but their parents, and sometimes even a whole nation of people.
Summary
Refugee children and their families experience a variety of traumas, often sustained across years and even decades, because of armed conflict, persecution, or social upheavals. It is known that refugees are at greater risk for PTSD and affective and psychotic disorders, presumably due to increased traumatic life events before, during, and after their migration. The writer uses his own experience as a child refugee from Vietnam to elucidate the stressors evident in various phases of forced displacement.

Since 1983, when I was a child and fled as a boat refugee from Vietnam with my mother, the international plight of displaced people has only worsened. From 1997 to 2022, the number of forcibly displaced people has more than tripled, growing from 34 million to more than 108 million.1
Displaced people are designated as refugees only when they cross international borders and meet the United Nations High Commissioner for Refugees’ (UNHCR) definition as “persons outside their countries of origin who are in need of international protection because of a serious threat to their life, physical integrity, or freedom in their country of origin as a result of persecution, armed conflict, violence, or serious public disorder.”2 There is a separate mandate by the United Nations for the aid of Palestinian refugees under the United Nations General Assembly’s United Nations Relief and Works Agency for Palestinian Refugees in the Near East (UNRWA).3 Of the displaced in 2022, more than 36 million were recognized as refugees under UNHCR and UNRWA mandates.1 Of these, almost 50% were children, at 17.5 million.4 To make matters worse, worldwide children represent less than one-third of the population.4 Since 2022, the increase in refugeeism is mostly driven by Ukraine and Syria, though also significantly Afghanistan, Venezuela, Sudan, Myanmar, Congo, Somalia, and Central African Republic.4 Refugeeism is a growing problem that disproportionately impacts children through sheer number, and one suspects, given their greater overall vulnerabilities compared with adults, physical and mental health consequences.
Traumas of refugees compared with non-refugee immigrants
In terms of mental health, refugees are distinct from non-refugee immigrants in that they likely experience more severe psychosocial adversities from greater poverty, greater risk of family separation, and uncertainty of the asylum process.5-8
From my own experience, this stems from the urgent nature of the refugee’s displacement, where they are often fleeing an immediate danger. My family had fled persecution from Communist forces and the social economic collapse that rendered Vietnam, for a time, one of the poorest in the world.9 Or, as my mother observed, “We had to leave because even doctors were starving.”
Refugees often have little preparation, have little legal protection since they are often criminalized, and are forced to endure dangerous conditions where they are vulnerable to smugglers and criminals who exploit their unprotected status. Once they arrive in their new country, they often do not have other family as social supports or resources. They themselves become the anchor for future legal and orderly immigration of their remaining family, given that they can extend their refugee status to those left behind.10 These non-refugee immigrants, unlike their refugee counterparts, are often flown to their new homes with more preparation, protecting them from dangerous conditions, and have the benefit of family who provide them with resources. As such, refugees tend to experience more traumatic life events than non-refugee immigrants. This was true in my family where those of us who initially escaped became the anchors to legally, and more safely, immigrate most of our family in Vietnam. We became their resources, likely making their acclimation smoother.
The mental health of refugee children and their caregivers
It is important to understand the stressors affecting the caregivers of children, since effective treatment of their mental health conditions can also benefit the children as well.11 In fact, among the greatest protective factors for refugee children is the presence of an adult caregiver, suggesting that the child’s mental health is dependent on the caregivers.
Those children who are separated show much worse mental health sequalae.12 As such, an understanding of the caregiver’s stressors is important. For example, when we were escaping Vietnam, my mom would protect me from our hardships by talking about our goals in America, minimizing our dangers by saying that we would be rewarded with things like a hamburger with its seemingly impossible amount of meat. Physically, my mother would always sleep with her arms around me and a knife hidden in order to ward off any attackers at night. When I was starving in the hull of a boat, having not eaten for days, my mother begged for food and gave me what she could get. And post-escape, my family focused on work and applied for aid for shelter and food, while encouraging us to invest in education, likely preventing involvement in criminal activities or gangs. Though overall, my family shielded me from the worst consequences, they also passed on their fears. One of my uncles had been killed by the police when he tried to escape, and so my family passed down a deep suspicion of authorities, whether they were the police or school principals. My mother had vivid memories of Communist re-education camps, which likely gave her a lasting fear that a Communist would find out our identities in America and re-capture us.
The mental health risk of refugees
Given that refugees tend to experience greater amounts of traumatic life events and a vast array of stressors sustained across years and even decades before, during, and after migration, it is no wonder they have much higher rates of mental health conditions, most predominantly PTSD and affective disorders.13,14 They are at particular risk of developing psychoses because they are more likely to experience a range of physical, psychological, and psychosocial problems associated with adversities such as violence, discrimination, economic stress, and social isolation.13 For example, the period leading up to my escape consisted of decades of prolonged war: the French-Indochina from 1945 to 1954, then the Vietnam War from 1955 to 1975) as well as the persecution and re-education camps afterward. What my family had to endure created a period of fear and loss into which I was born into in 1976. That year, my family had lost its fortune due to the Communist government seizing of our home and business, plunging us from a comfortable middle- to upper-class life to poverty. There was also widespread fear of systematic rape by the Communist victors. So my family endured great stress and the loss of a way of life leading up to our escape.

CKD-EPI eGFR formula surpasses alternatives in young adults
PHILADELPHIA –
The two alternative formulas for calculating eGFR, the CKiD U25 (Chronic Kidney Disease in Children under 25) and the European Kidney Function Consortium equations, showed higher levels of bias that resulted in underestimates of kidney function, particularly in younger adults 18-25 years old and in those with higher eGFR values, Leslie A. Inker, MD, said at Kidney Week 2023, organized by the American Society of Nephrology.
However, for young adults with a history of childhood CKD and especially for those who continue under the care of pediatric clinicians even after they become young adults, use of the CKiD U25 equation, remains a reasonable option, said Dr. Inker, professor and director of the Kidney and Blood Pressure Center at Tufts Medical Center in Boston. The CKiD U25 equation is intended for people aged 1-25 years and came out in late 2020.
Pediatric nephrologists use the CKiD U25 but the results of the 2021 CKD-EPI race-free equation is what U.S. clinical labs routinely report for people aged 18 or older. “Our findings support the current practice of pediatric nephrologists” who may opt to use the CKiD U25 even when a patient turns 18 years or older, Dr. Inker said in an interview.
But the new results also support the current practice of U.S. labs, which is to focus on calculating eGFR in anyone at least 18 years old using the 2021 equation developed by the CKD-EPI, work led by Dr. Inker. The new findings confirm routine use of the 2021 CKD-EPI equation in adults as young as 18 years old, especially when they’re having their eGFR calculated for the first time, she said.
Discontinuity changing from CKiD U25 to CKD-EPI is ‘not huge’
“It’s important to understand that the 2021 CKD-EPI equation works in young adults,” noted Josef Coresh, MD, PhD, professor of clinical epidemiology at Johns Hopkins University, Baltimore, who collaborated on both the current study and on developing the 2021 CKD-EPI equation.
The new data show that the discontinuity in eGFR produced by switching from the CKiD U25 formula to the 2021 CKD-EPI formula “is not huge, maybe about 5 mL/min per 1.73 m2 higher. People should focus on the new baseline and subsequent trends, not the modest difference between equations,” Dr. Coresh advised in an interview.
The study run by Dr. Inker and her associates used 1,491 people aged 18-40 years and enrolled in a cohort created by the CKD-EPI. They compared measured GFR levels in each subject with the estimates generated by the 2021 race-free CKD-EPI equation, the CKiD U25 equation, and a third equation developed by the EKFC and introduced in 2021.
Less bias with the 2021 CKD-EPI equation
The researchers compared the three eGFR equations with their respective measured GFR values by two metrics: bias, defined as the median difference between measured and estimated GFR; and the percentage of eGFR values that fell within 30% of the corresponding measured GFR value.
The results showed that bias was lowest using the 2021 CKD-EPI equation, with an overall median difference of 0.5 mL/min per 1.73 m2. This compared with median differences of 7.2 with the CKiD U25 equation and 4.9 mL/min per 1.73 m2 with the EKFC equation. The disparity in bias was greatest among those with eGFR values in the range of 60-90 mL/min per 1.73 m2 and was also greatest for those 18-25 years old.
The CKD-EPI equation results also showed the greatest consistency of bias across the entire 18- to 40-year-old range. Between-group differences were small for the percentage of eGFR values that fell within 30% of measured GFR, with all three equations scoring in the range of 88%-90%.
The study received no commercial funding. Dr. Inker is a consultant to Diamtrix and her department receives research funding from Chinook, Omeros, Reata, and Tricida. Dr. Coresh is a consultant to Healthy.io and SomaLogic and he has an ownership interest in Healthy.io.

But the new results also support the current practice of U.S. labs, which is to focus on calculating eGFR in anyone at least 18 years old using the 2021 equation developed by the CKD-EPI, work led by Dr. Inker. The new findings confirm routine use of the 2021 CKD-EPI equation in adults as young as 18 years old, especially when they’re having their eGFR calculated for the first time, she said.
Discontinuity changing from CKiD U25 to CKD-EPI is ‘not huge’
“It’s important to understand that the 2021 CKD-EPI equation works in young adults,” noted Josef Coresh, MD, PhD, professor of clinical epidemiology at Johns Hopkins University, Baltimore, who collaborated on both the current study and on developing the 2021 CKD-EPI equation.
The new data show that the discontinuity in eGFR produced by switching from the CKiD U25 formula to the 2021 CKD-EPI formula “is not huge, maybe about 5 mL/min per 1.73 m2 higher. People should focus on the new baseline and subsequent trends, not the modest difference between equations,” Dr. Coresh advised in an interview.
The study run by Dr. Inker and her associates used 1,491 people aged 18-40 years and enrolled in a cohort created by the CKD-EPI. They compared measured GFR levels in each subject with the estimates generated by the 2021 race-free CKD-EPI equation, the CKiD U25 equation, and a third equation developed by the EKFC and introduced in 2021.
Less bias with the 2021 CKD-EPI equation
The researchers compared the three eGFR equations with their respective measured GFR values by two metrics: bias, defined as the median difference between measured and estimated GFR; and the percentage of eGFR values that fell within 30% of the corresponding measured GFR value.
The results showed that bias was lowest using the 2021 CKD-EPI equation, with an overall median difference of 0.5 mL/min per 1.73 m2. This compared with median differences of 7.2 with the CKiD U25 equation and 4.9 mL/min per 1.73 m2 with the EKFC equation. The disparity in bias was greatest among those with eGFR values in the range of 60-90 mL/min per 1.73 m2 and was also greatest for those 18-25 years old.
The CKD-EPI equation results also showed the greatest consistency of bias across the entire 18- to 40-year-old range. Between-group differences were small for the percentage of eGFR values that fell within 30% of measured GFR, with all three equations scoring in the range of 88%-90%.
The study received no commercial funding. Dr. Inker is a consultant to Diamtrix and her department receives research funding from Chinook, Omeros, Reata, and Tricida. Dr. Coresh is a consultant to Healthy.io and SomaLogic and he has an ownership interest in Healthy.io.
PHILADELPHIA –
The two alternative formulas for calculating eGFR, the CKiD U25 (Chronic Kidney Disease in Children under 25) and the European Kidney Function Consortium equations, showed higher levels of bias that resulted in underestimates of kidney function, particularly in younger adults 18-25 years old and in those with higher eGFR values, Leslie A. Inker, MD, said at Kidney Week 2023, organized by the American Society of Nephrology.
However, for young adults with a history of childhood CKD and especially for those who continue under the care of pediatric clinicians even after they become young adults, use of the CKiD U25 equation, remains a reasonable option, said Dr. Inker, professor and director of the Kidney and Blood Pressure Center at Tufts Medical Center in Boston. The CKiD U25 equation is intended for people aged 1-25 years and came out in late 2020.
Pediatric nephrologists use the CKiD U25 but the results of the 2021 CKD-EPI race-free equation is what U.S. clinical labs routinely report for people aged 18 or older. “Our findings support the current practice of pediatric nephrologists” who may opt to use the CKiD U25 even when a patient turns 18 years or older, Dr. Inker said in an interview.

Pregnancies with low anti-SSA/Ro autoantibody levels: Forgo fetal heart rhythm monitoring?
SAN DIEGO – Pregnant women with anti-SSA/Ro autoantibodies at titer levels of less than 1,000 ELISA units per mL are at minimal to no risk for fetal atrioventricular (AV) block and may be able to forgo traditional echocardiographic heart rhythm monitoring, results from an ongoing, prospective, multicenter trial demonstrated.
However, pregnant patients with higher titer antibodies seem to be at greatest risk for fetal AV block and may benefit from ambulatory fetal heart rhythm monitoring (FHRM), which can detect emergent AV block, according to the study findings. The findings were published online in Arthritis & Rheumatology and will be presented Nov. 13 at the American College of Rheumatology (ACR) 2023 Annual Meeting by Jill P. Buyon, MD, a rheumatologist who directs the division of rheumatology and the Lupus Center at NYU Langone Health in New York.
“While anti-Ro antibodies have been known to be associated with AV block for decades, it has become increasingly clear that antibody titers matter,” Dr. Buyon said in an interview.
For the investigation, which is the largest of its kind, researchers at 22 sites drew from the large multiracial national study of pregnant women, Surveillance To Prevent AV Block Likely to Occur Quickly (STOP BLOQ), to address the impact of anti-Ro titers and use of frequent ambulatory FHRM on outcomes in women with no previously affected children and those at risk for recurrence. Monitoring occurred during the second trimester of pregnancy (from 17 weeks through 26 weeks) and consisted of daily fetal home testing by mothers using handheld, commercially available Doppler devices.
These were followed up by weekly or biweekly echocardiograms, and ultrasound tests to evaluate fetal heart rhythm and function, as well as to show any structural problems. Three times per day, the pregnant women texted the Doppler sound recordings in real time to a pediatric cardiologist, who immediately ordered an additional echocardiogram in cases of irregular or slowing fetal heart rates. If second-degree heart block was detected, drug therapy was initiated.
No AV block seen with low anti-Ro titers
Dr. Buyon, who led the study with Bettina Cuneo, MD, clinical scholar and professor of surgery and pediatrics at the University of Arizona in Tucson, presented findings from 413 pregnant subjects with a mean age of 33 years who finished monitoring surveillance: 152 women had low titers of both anti-Ro60 and –Ro52 (defined as < 1,000 ELISA units per mL), and 261 women with titers above the threshold for either antibody (defined as ≥ 1,000 ELISA units per mL). Of the 152 women with low titers of both anti-Ro60 and –Ro52, none of the pregnancies past 26 weeks resulted in AV block. Of the 261 women with titers above the threshold for either antibody, 10 of the pregnancies resulted in AV block (3.8%). The incidence of AV block increased with higher antibody titer levels, reaching 7.7% for those in the top quartile for anti–60-kD SSA/Ro; this increased to 27.3% in study participants with a previous child who had AV block, although numbers in this category were small.
Analysis of cumulative FHRM recordings between surveillance echocardiograms revealed that no case of second-degree or third-degree AV block was missed. In addition, 70% of AV blocks detected by FHRM were second-degree and all occurred less than 12 hours from normal FHRM and within another 45 minutes to 4.5 hours to echocardiogram. The one case of second/third-degree and two cases of third-degree AV block were diagnosed by urgent echocardiogram more than 17 to 72 hours from a previously normal FHRM episode.
Other factors besides high anti-Ro titer likely play a role
“STOP BLOQ nicely demonstrates that low titer is associated with a very low risk AV block, and intense monitoring may not be needed,” Dr. Buyon told this news organization. “However, high titer is not the whole answer since even women with the very highest titers can have healthy babies. This report also shows that titers stay constant through pregnancies in the same mother, whether there is the complication of AV block or not. This suggests other factors contribute to AV block.”
She added that FHRM can be easily performed by the mother, but at this time is still best interpreted by a cardiologist. “FHRM detected all cases of AV block, which can happen in hours,” she said. “FHRM should decrease the need for frequent echocardiograms. Some mothers do have more difficulty in deciding whether the baby’s heart is beating irregularly. We need [to improve our teaching] and for how best to have a cardiologist or trained listener interpret. FHRM can be done by the mother but needs interpretation by a cardiologist until we develop a device which can identify abnormalities.”
She acknowledged certain limitations of the study, including the fact that a commercial test for anti-SSA/Ro antibody levels is not available to all clinicians. “Try to find a lab that measures high titer anti-Ro antibodies, but if not, then use one of the common commercial tests such as the BioPlex 2000 autoimmune panels and consider decreased surveillance if titer is < 8,” Dr. Buyon advised.
Vaneet K. Sandhu, MD, a rheumatologist with Loma Linda (Calif.) Medical Center, who was asked to comment on the work, said that the study not only justifies the limited use of FHRM in those with high titer antibodies (followed by urgent fetal echocardiography where indicated), but also risk stratification for fetal AV block.
“For years, we have recommended frequent fetal echocardiography testing in pregnant women with positive anti-SSA/Ro,” Dr. Sandhu said. “This study tells us we need to look deeper. On one hand, recognizing that low titer anti-Ro antibodies do not confer a risk of AV block is cost effective. On the other hand, while the titer of the antibody appears to contribute to fetal AV block, we need to delve deeper into additional factors contributing to fetal AV block risk in order to better navigate our surveillance methods.”
The study was supported by NIH grants from the National Institute of Child Health and Human Development and the National Institute of Arthritis and Musculoskeletal and Skin Diseases. Dr. Sandhu has disclosed no relevant financial relationships.

Alpha-gal syndrome: Red meat is ‘just the beginning,’ expert says
ANAHEIM, CALIF. – allergist and immunologist Scott P. Commins, MD, PhD, told attendees at the annual meeting of the American College of Allergy, Asthma, and Immunology (ACAAI) annual meeting.
Dr. Commins, associate chief for allergy and immunology at the University of North Carolina at Chapel Hill, has made alpha-gal, a potentially fatal allergy, which, in the United States is tied to the bite of the Lone Star tick, his primary research focus.
Beyond red meat, “there are some people who are allergic to all things mammal,” he explained. Dairy products from mammals, medical devices made from mammalian products, vaccines and medicines that contain gelatin, and even commercial products such as perfumes and cosmetics may be behind an AGS reaction.
“The derived products from pigs and cows really find their way into a lot of our day-to-day products,” he said. “I try to keep an open mind about these exposures.”
Physicians should also be aware that “this can happen to kids,” said Dr. Commins. “It looks very similar to adults’ [AGS]. They can end up in the emergency department.”
He also had clinical advice about food challenges for AGS. He explained that there’s more alpha-gal in beef than in other red meats (including pork, venison, and lamb) with the exception of pork kidney. Pork kidney, he said, “has the most alpha-gal that we can find in the lab.”
Dr. Commins said he has stopped using beef for AGS food challenges and has switched to pork sausage patties with a high fat content microwaved in the clinic because they have less alpha-gal in general and he views them as safer.
Long delay in symptom onset
AGS symptoms typically take 2-6 hours to appear after eating red meat or being exposed to mammalian products, but Dr. Commins related a story about a patient he sent home who had very mild symptoms (some lower back itching) after he had spent the day at the clinic after a pork sausage food challenge for AGS.
The patient had returned home. Eight hours after the food challenge, his wife sent Dr. Commins a picture of her husband’s back, which was riddled with welts and was itching badly.
“I learned that if you’re going to do these food challenges, if there is a hint of symptoms at the clinic at 6 hours, keep them in the clinic, because it may really take that long to evolve,” Dr. Commins said.
One of the early signs he’s discovered is palmar erythema (redness and swelling of the hands).
Research has shown that AGS has been heavily concentrated in the Southeast, where Lone Star tick populations are clustered, but research has shown that from 2017 to 2022, it moved up the East Coast to the central United States and Upper Midwest.
“We are seeing increasing diagnoses of AGS in places that are not, perhaps, where we first thought this allergy existed,” said Dr. Commins. “Stay aware,” he cautioned.
The allergy is not exclusive to the United States, he noted. In Europe and Australia, for example, AGS is not thought to be tied to the Lone Star tick, which doesn’t inhabit those regions.
“It is a global phenomenon,” Dr. Commins said.
In August, the CDC alerted physicians to emerging cases of alpha-gal allergy after an article in Morbidity and Mortality Weekly Report indicated that health care providers have little knowledge about the allergy. Of the 1,500 health care providers surveyed, 42% had never heard of the syndrome, and another 35% were not confident in diagnosing or managing affected patients.
Matthew Lau, MD, an allergist with Kaiser Permanente in Honolulu who listened to Dr. Commins’ talk, told this news organization, “It’s important to raise awareness in primary care particularly, he said, as “allergists see only a fraction of the [AGS] patients.”
Allergists can help raise awareness
“Allergists have a role to alert the general community” and to drive more referrals, he said. That includes emergency departments, where physicians commonly see anaphylaxis.
Dr. Lau said he expects the incidence of AGS to increase, because global warming will likely lengthen warmer seasons and cause the geographic distribution to change.
Jay Lieberman, MD, a pediatric allergist at Le Bonheur Children’s Hospital in Memphis, Tenn., told this news organization, “There’s still a lot of confusion, and hearing from an expert like Dr. Commins helps tease out the not-obvious things about patients who are having more mild symptoms,” such as from allergy to dairy or medicines or vaccines that contain gelatin.
As a pediatric allergist, Dr. Lieberman said he sees less alpha-gal than his colleagues, but, he said, “On the adult side in Tennessee, it’s rampant.”
Dr. Commins, Dr. Lieberman, and Dr. Lau report no relevant financial relationships.

“Allergists have a role to alert the general community” and to drive more referrals, he said. That includes emergency departments, where physicians commonly see anaphylaxis.
Dr. Lau said he expects the incidence of AGS to increase, because global warming will likely lengthen warmer seasons and cause the geographic distribution to change.
Jay Lieberman, MD, a pediatric allergist at Le Bonheur Children’s Hospital in Memphis, Tenn., told this news organization, “There’s still a lot of confusion, and hearing from an expert like Dr. Commins helps tease out the not-obvious things about patients who are having more mild symptoms,” such as from allergy to dairy or medicines or vaccines that contain gelatin.
As a pediatric allergist, Dr. Lieberman said he sees less alpha-gal than his colleagues, but, he said, “On the adult side in Tennessee, it’s rampant.”
Dr. Commins, Dr. Lieberman, and Dr. Lau report no relevant financial relationships.

ANAHEIM, CALIF. – allergist and immunologist Scott P. Commins, MD, PhD, told attendees at the annual meeting of the American College of Allergy, Asthma, and Immunology (ACAAI) annual meeting.
Dr. Commins, associate chief for allergy and immunology at the University of North Carolina at Chapel Hill, has made alpha-gal, a potentially fatal allergy, which, in the United States is tied to the bite of the Lone Star tick, his primary research focus.
Beyond red meat, “there are some people who are allergic to all things mammal,” he explained. Dairy products from mammals, medical devices made from mammalian products, vaccines and medicines that contain gelatin, and even commercial products such as perfumes and cosmetics may be behind an AGS reaction.
“The derived products from pigs and cows really find their way into a lot of our day-to-day products,” he said. “I try to keep an open mind about these exposures.”
Physicians should also be aware that “this can happen to kids,” said Dr. Commins. “It looks very similar to adults’ [AGS]. They can end up in the emergency department.”
He also had clinical advice about food challenges for AGS. He explained that there’s more alpha-gal in beef than in other red meats (including pork, venison, and lamb) with the exception of pork kidney. Pork kidney, he said, “has the most alpha-gal that we can find in the lab.”
Dr. Commins said he has stopped using beef for AGS food challenges and has switched to pork sausage patties with a high fat content microwaved in the clinic because they have less alpha-gal in general and he views them as safer.
Long delay in symptom onset
AGS symptoms typically take 2-6 hours to appear after eating red meat or being exposed to mammalian products, but Dr. Commins related a story about a patient he sent home who had very mild symptoms (some lower back itching) after he had spent the day at the clinic after a pork sausage food challenge for AGS.
The patient had returned home. Eight hours after the food challenge, his wife sent Dr. Commins a picture of her husband’s back, which was riddled with welts and was itching badly.
“I learned that if you’re going to do these food challenges, if there is a hint of symptoms at the clinic at 6 hours, keep them in the clinic, because it may really take that long to evolve,” Dr. Commins said.
One of the early signs he’s discovered is palmar erythema (redness and swelling of the hands).
Research has shown that AGS has been heavily concentrated in the Southeast, where Lone Star tick populations are clustered, but research has shown that from 2017 to 2022, it moved up the East Coast to the central United States and Upper Midwest.
“We are seeing increasing diagnoses of AGS in places that are not, perhaps, where we first thought this allergy existed,” said Dr. Commins. “Stay aware,” he cautioned.
The allergy is not exclusive to the United States, he noted. In Europe and Australia, for example, AGS is not thought to be tied to the Lone Star tick, which doesn’t inhabit those regions.
“It is a global phenomenon,” Dr. Commins said.
In August, the CDC alerted physicians to emerging cases of alpha-gal allergy after an article in Morbidity and Mortality Weekly Report indicated that health care providers have little knowledge about the allergy. Of the 1,500 health care providers surveyed, 42% had never heard of the syndrome, and another 35% were not confident in diagnosing or managing affected patients.
Matthew Lau, MD, an allergist with Kaiser Permanente in Honolulu who listened to Dr. Commins’ talk, told this news organization, “It’s important to raise awareness in primary care particularly, he said, as “allergists see only a fraction of the [AGS] patients.”
