Poverty is known to be associated with poor health outcomes throughout life. Now, new research has shown that, from as early as the second trimester of pregnancy, fetuses are already feeling the effects of poverty.

“There is a well-recognized health inequality where quality and duration of life are lower among the most poor. This divide is present both within and between countries,” said Steve Turner, who led the study.

Given the association of poverty and low birth weight, the authors of the new multi-national study, published in the Journal of Epidemiology and Community Health, hypothesized that “individuals from highest household income compared to those with lowest household income will have increased fetal size in the second and third trimester and birth.”

For their study, researchers from the University of Aberdeen gathered details of ante-natal and birth size – second and third trimester fetal ultrasound measurements of estimated fetal weight, biparietal diameter, and femur length, as well as birth measurements of weight, occipitofrontal circumference, and crown heel length – from eight cohorts that included 21,714 individuals from nations including Scotland, England, Saudi Arabia, the U.S., Netherlands, Spain, Norway, Sweden, and France.

They then related these to household income, taking into account other factors, including mother’s age, height, number of other children, and smoking, analyzing the data using cross-sectional two-stage individual patient data analyses and a longitudinal one-stage individual patient data analysis.
 

Household income closely related to birth size

The authors found that higher household income was associated with larger fetal head size and weight but not length, from the second half of pregnancy, compared with lowest household income. They said that their results argue for “a relationship where household income is closely related to birth size.”

The results showed that, across the countries studied, babies were smaller at birth if they came from a lower income household, and this discrepancy in size was already apparent at 20 weeks gestation.

“This is the first time that size differences have been found at such an early stage of development,” the authors said, “and also the first time it has been compared across continents.”

Professor Turner pointed out that “what this study shows is that the inequality, as seen by reduced size in fetal life, is present long before birth, and this poverty gap widens between twenty weeks gestation and birth.”

He added: “Basically, regardless of whether you live in Saudi, the U.S., or Europe, and accounting for things that might affect fetal growth, if your parents are poor, you will be smaller before birth and at birth compared to if your parents were not poor.”
 

Increase engagement with pregnant mothers living in poverty

He emphasized how this was problematic, as small size before and after birth puts an individual at “increased risk for many serious illnesses in later life.”

The authors hope that this study will encourage health care providers to recognize the health risks associated with lower income for mothers and their unborn children and to provide more support and guidance to mitigate the risks.

They said, “interventions aimed at softening the impact of poverty on pregnant mothers could reduce incidence of small for gestational age and the associated burden of excessive morbidity and mortality throughout the life course.”

Professor Turner described how the mechanisms that drive this inequity may be explained by pregnant mothers from poor households having difficulty in accessing or engaging with antenatal care. 

“We would like to see health care providers around the world strive to increase engagement with pregnant mothers living in poverty,” he said. “This engagement will reward all of society by putting unborn children on a trajectory to longer and healthier lives.”

It was a good run while it lasted.

New COVID-19 cases in U.S. children had dropped for 11 consecutive weeks, but that streak has come to an end, as cases increased 28% during the week of April 8-14, according to the American Academy of Pediatrics and the Children’s Hospital Association.

The number of reported pediatric cases for the week was 33,146, and the actual increase from the previous week was just 7,231 cases, the AAP and CHA said, but some reports suggest that the new COVID variants and subvariants are starting to have an effect on incidence in some areas while mask mandates continue to fall.

Data from the Centers for Disease Control and Prevention show that, over the last week or two, the 7-day average for percentage of emergency department visits with diagnosed COVID has risen from 0.5% to 0.6% in children aged 0-11 years, from 0.3% to 0.5% among 12- to 15-year-olds, and from 0.3% to 0.4% in 16- and 17-year-olds. Small increases, to be sure, but increases nonetheless.

A somewhat similar scenario is playing out for new admissions of children aged 0-17, which have leveled out after dropping from a high of 1.25 per 100,000 population in mid-January to 0.13 per 100,000 in early April. Over the last 2 weeks, the rate has been alternating between 0.13 and 0.14 per 100,000, the CDC said on its COVID Data Tracker.

The latest news on the vaccination front came from Pfizer and BIoNTech, which announced that a third dose of its COVID-19 vaccine boosted immune protection in children aged 5-11 years in a phase 2/3 trial. Protection against the Omicron strain was 36 times higher than the two previous doses, the companies said, adding that they plan to submit a request for emergency use authorization of a booster dose in the near future.

The ongoing vaccination effort, however, produced mixed results in the last week. Initial vaccinations among children aged 5-11 years fell 14.5% to another new low while initial doses were up 9.3% for those aged 12-17, the AAP said. Overall, just 28.2% of the country’s 5- to 11-year-olds are fully vaccinated, compared with 58.7% of those aged 12-17, the CDC reported.

Emotional or sexual abuse in childhood may increase risk of multiple sclerosis (MS) in women, and risk may increase further with exposure to multiple kinds of abuse, according to the first prospective cohort study of its kind.

More research is needed to uncover underlying mechanisms of action, according to lead author Karine Eid, MD, a PhD candidate at Haukeland University Hospital, Bergen, Norway, and colleagues.

“Trauma and stressful life events have been associated with an increased risk of autoimmune disorders,” the investigators wrote in the Journal Of Neurology, Neurosurgery, & Psychiatry. “Whether adverse events in childhood can have an impact on MS susceptibility is not known.”

The present study recruited participants from the Norwegian Mother, Father and Child cohort, a population consisting of Norwegian women who were pregnant from 1999 to 2008. Of the 77,997 participating women, 14,477 reported emotional, sexual, and/or physical abuse in childhood, while the remaining 63,520 women reported no abuse. After a mean follow-up of 13 years, 300 women were diagnosed with MS, among whom 24% reported a history of childhood abuse, compared with 19% among women who did not develop MS.

To look for associations between childhood abuse and risk of MS, the investigators used a Cox model adjusted for confounders and mediators, including smoking, obesity, adult socioeconomic factors, and childhood social status. The model revealed that emotional abuse increased the risk of MS by 40% (hazard ratio [HR] 1.40; 95% confidence interval [CI], 1.03-1.90), and sexual abuse increased the risk of MS by 65% (HR 1.65; 95% CI, 1.13-2.39).

Although physical abuse alone did not significantly increase risk of MS (HR 1.31; 95% CI, 0.83-2.06), it did contribute to a dose-response relationship when women were exposed to more than one type of childhood abuse. Women exposed to two out of three abuse categories had a 66% increased risk of MS (HR 1.66; 95% CI, 1.04-2.67), whereas women exposed to all three types of abuse had the highest risk of MS, at 93% (HR 1.93; 95% CI, 1.02-3.67).

Dr. Eid and colleagues noted that their findings are supported by previous retrospective research, and discussed possible mechanisms of action.

“The increased risk of MS after exposure to childhood sexual and emotional abuse may have a biological explanation,” they wrote. “Childhood abuse can cause dysregulation of the hypothalamic-pituitary-adrenal axis, lead to oxidative stress, and induce a proinflammatory state decades into adulthood. Psychological stress has been shown to disrupt the blood-brain barrier and cause epigenetic changes that may increase the risk of neurodegenerative disorders, including MS.

“The underlying mechanisms behind this association should be investigated further,” they concluded.
 

Study findings should guide interventions

Commenting on the research, Ruth Ann Marrie, MD, PhD, professor of medicine and community health sciences and director of the multiple sclerosis clinic at Max Rady College of Medicine, Rady Faculty of Health Sciences, University of Manitoba, Winnipeg, said that the present study “has several strengths compared to prior studies – including that it is prospective and the sample size.”

Dr. Marrie, who was not involved in the study, advised clinicians in the field to take note of the findings, as patients with a history of abuse may need unique interventions.

“Providers need to recognize the higher prevalence of childhood maltreatment in people with MS,” Dr. Marrie said in an interview. “These findings dovetail with others that suggest that adverse childhood experiences are associated with increased mental health concerns and pain catastrophizing in people with MS. Affected individuals may benefit from additional psychological supports and trauma-informed care.”

Tiffany Joy Braley, MD, associate professor of neurology, and Carri Polick, RN and PhD candidate at the school of nursing, University of Michigan, Ann Arbor, who published a case report last year highlighting the importance of evaluating stress exposure in MS, suggested that the findings should guide interventions at both a system and patient level.

“Although a cause-and-effect relationship cannot be established by the current study, these and related findings should be considered in the context of system level and policy interventions that address links between environment and health care disparities,” they said in a joint, written comment. “Given recent impetus to provide trauma-informed health care, these data could be particularly informative in neurological conditions which are associated with high mental health comorbidity. Traumatic stress screening practices could lead to referrals for appropriate support services and more personalized health care.”

While several mechanisms have been proposed to explain the link between traumatic stress and MS, more work is needed in this area, they added.

This knowledge gap was acknowledged by Dr. Marrie.

“Our understanding of the etiology of MS remains incomplete,” Dr. Marrie said. “We still need a better understanding of mechanisms by which adverse childhood experiences lead to MS, how they interact with other risk factors for MS (beyond smoking and obesity), and whether there are any interventions that can mitigate the risk of developing MS that is associated with adverse childhood experiences.”

The investigators disclosed relationships with Novartis, Biogen, Merck, and others. Dr. Marrie receives research support from the Canadian Institutes of Health Research, the National Multiple Sclerosis Society, MS Society of Canada, the Consortium of Multiple Sclerosis Centers, Crohn’s and Colitis Canada, Research Manitoba, and the Arthritis Society; she has no pharmaceutical support. Dr. Braley and Ms. Polick reported no conflicts of interest.

The Diagnosis: Epidermolysis Bullosa

Our patient was found to have epidermolysis bullosa (EB), a rare genetic disease in which the superficial layers of the skin separate to form vesicles or bullae due to a mutation in the keratin 14 gene, KRT14. Separation of the skin occurs due to cleavage of various proteins that connect the epidermis to the dermis. A genetic mutation in KRT14, one of the more common genetic mutations associated with EB, results in cleavage at the basal epidermal protein keratin 14. The skin of individuals with EB typically is fragile and cannot tolerate friction or manipulation due to the risk for new bullae formation.¹ Epidermolysis bullosa is rare, affecting approximately 20 children per 1 million births in the United States, and is not commonly seen by most general adult dermatologists.²

In our patient, the differential diagnoses included staphylococcal scalded skin syndrome (SSSS), Stevens-Johnson syndrome/toxic epidermal necrolysis (SJS/TEN), herpes simplex virus (HSV), and bullous pemphigoid (BP). Symptoms of SSSS can range from mild and localized to full-body exfoliation of the skin. Although SSSS can resemble other bullous disorders, its etiology arises from the Staphylococcus exotoxin targeting desmoglein in the stratum granulosum— the layer of the epidermis between the stratum corneum and stratum spinosum.³ Lesions start on the face, neck, and body folds, which was consistent with our patient’s presentation. However, bullae continued to develop in our patient despite antibiotic therapy, which reduced the likelihood of SSSS. Stevens-Johnson syndrome/toxic epidermal necrolysis develops rapidly and often involves the mucosa, which our patient initially did not have. In children, SJS/TEN can develop secondary to infection, whereas in adults it more commonly is associated with medication administration.⁴ Although the mother tested negative for HSV, the infant was started on acyclovir, which ultimately was discontinued due to low clinical suspicion. The clinical presentation of HSV (ie, clustered vesicles) was not consistent with our patient’s presentation. Bullous pemphigoid is a subepithelial blistering disease seen in older adults. Tense, fluidfilled blisters primarily are seen on the trunk and flexures. Although infantile BP can occur, it usually does not present in the neonatal period but rather at approximately 3 to 5 months of age.⁵

High clinical suspicion for EB due to the common characteristics of bullae location and formation following skin manipulation led to genetic testing in our patient. Mild forms of EB simplex typically appear on the upper and lower extremities with sparing of the trunk. In more severe cases of EB simplex, truncal and mucosal involvement may occur.⁶ In our case, the infant had a classic distribution of arm and leg blisters with truncal sparing. Epidermolysis bullosa may not be diagnosed in the neonatal period because of its similarities to other more common diseases, such as HSV or bullous impetigo, or other genetic blistering diseases, such as epidermolytic ichthyosis and incontinentia pigmenti.⁶

Epidermolysis bullosa can be inherited in an autosomal-dominant or autosomal-recessive fashion or with de novo mutations and is classified based on the location of cleavage in the skin. The 4 classical subtypes— simplex, junctional, dystrophic, and Kindler—have now been further subclassified. Epidermolysis bullosa simplex (intraepidermal split) is now separated into basal and suprabasal, with further subclassification including the distribution of blisters (generalized or localized) and the severity of cutaneous or extracutaneous involvement.⁷

In our case, the infant was found to have intraepidermal EB (simplex) due to a KRT14 mutation (missense mutation).⁶ KRT14 (17q21.2) and KRT5 (12q13.3) are the 2 most common mutations causing cleavage at the basal intraepidermal layer. Thickening of the palms, soles, and nails can be seen; however, blisters heal well without scarring, as seen in our patient. Junctional EB due to cleavage at the intralamina lucida often involves mutations in laminin 332, plectin, and α6β4 integrin. Infants with junctional EB often die from severe infection, dehydration, or malnutrition due to mucosal involvement. Dystrophic EB occurs due to a collagen VII mutation in the dermis, leading to blisters at the sublamina densa and more severe symptoms in the recessive form.⁷

Newborn management for infants with EB differs from normal newborn care due to increased skin fragility with physical manipulation. Minimal skin manipulation and proper wound care are essential from the first day of life. For new bullae formation, bullae should be ruptured with a needle at the base of the blister and drained. The remaining skin overlying the wound should remain in place as a natural wound barrier. Patients with EB should not have tape or adhesive bandages applied directly to the skin. Instead, nonadhesive dressings can be placed directly on wounds and covered in soft wraps circumferentially. Dressings can be taped together without involving the skin. The cost for supplies for families to manage bullae is expensive. Fortunately, there are resources available for supplies and support for families, including the EB Research Partnership (https://www.ebresearch.org/) and DEBRA of America (https://www.debra.org/).

Currently, there is no cure for EB. Current treatment involves wound care, prevention, and symptomatic relief. Prevention includes avoiding activities that may result in increased friction of the skin and ensuring careful manipulation. Children with EB may have pain or itching from their blisters, which can be treated with oral acetaminophen or ibuprofen and diphenhydramine, respectively. Other complications of EB include anemia, dehydration, constipation, infection, and malnutrition. In more severe forms of EB, complications including eye problems, mucosal strictures, and skin cancer may occur.⁸ Future treatment directions include gene therapy, bone marrow transplantation, protein replacement therapies, and cell-based therapies. Prognosis for infants with EB due to KRT14 mutation is good, as it is a milder subtype of EB with a full life expectancy and improvement of blistering skin with age. The most at-risk time for early death is during infancy due to increased risk for infection.⁸ In this case, our patient showed full healing with no scar formation, which suggested a reassuring prognosis.

The Diagnosis: Epidermolysis Bullosa

Our patient was found to have epidermolysis bullosa (EB), a rare genetic disease in which the superficial layers of the skin separate to form vesicles or bullae due to a mutation in the keratin 14 gene, KRT14. Separation of the skin occurs due to cleavage of various proteins that connect the epidermis to the dermis.

Older age and higher ferritin levels at hospital admission predict severe illness in COVID-related multisystem inflammatory syndrome in children (MIS-C), according to a Canadian multicenter cohort study.

The adjusted absolute risk for admission to an intensive care unit was 43.6% among children aged 6 years and older and 46.2% in children aged 13 to 17 years, compared with 18.4% in children aged 5 years or younger.

“We do not understand why teens get more severe MIS-C than younger children,” senior author Joan Robinson, MD, of the University of Alberta, Edmonton, told this news organization. “It is possible that more exposures to other coronaviruses in the past result in them having a more robust immune response to SARS-CoV-2, which results in more inflammation.”

The data were published  in the Canadian Medical Association Journal.
 

A multinational study

The study included data on 232 children admitted with probable or confirmed MIS-C at 15 hospitals in Canada, Iran, and Costa Rica between March 1, 2020, and March 7, 2021. The median age of the children was 5.8 years, 56.0% were boys, and 21.6% had comorbidities.

Although cardiac involvement was common (58.6%), and almost one-third of the cohort (31.5%) was admitted to an ICU, “recovery was typically rapid, with 85% of patients discharged within 10 days,” said Dr. Robinson, for the Pediatric Investigators Collaborative Network on Infections in Canada (PICNIC).
 

Older age as a risk

The results suggest that older age is associated with increased risk of severe MIS-C. “However, one would then predict that adults would be at even higher risk than teens, whereas the same syndrome in adults (MIS-A) is very, very rare,” said Dr. Robinson.

The study also found that children admitted with ferritin levels greater than 500 μg/L, signaling greater inflammation, also had an increased risk for ICU admission, compared with those with lower levels (adjusted risk difference, 18.4%; relative risk, 1.69). “This is presumably because the more inflammation that the child has, the more likely they are to have inflammation of the heart, which can lead to low blood pressure,” said Dr. Robinson.
 

Features of MIS-C

Among all patients with MIS-C, gastrointestinal involvement was common (89.2%), as were mucocutaneous findings (84.5%). Children with MIS-C had fever for a median duration of 6 days. “Clinicians who see children in their practice commonly have to determine why a child is febrile. Our study shows that one mainly has to consider MIS-C if febrile children have a rash and one or more of vomiting, diarrhea, or abdominal pain,” said Dr. Robinson. 

The study also found that patients with MIS-C who were admitted to the hospital in the latter part of the study period (Nov. 1, 2020, to March 7, 2021) were slightly more likely to require ICU admission, compared with those admitted between March 1 and Oct. 31, 2020. “We cannot provide a clear explanation [for this],” the authors noted. “The features of severe MIS-C were widely publicized by May 2020, so it seems unlikely that severe cases were missed early in the study period. SARS-CoV-2 variants of concern have replaced the wild-type virus. It is possible that the immune response to circulating variants alters the severity of COVID-19 and MIS-C, when compared with wild-type virus.”

Despite initial concerns that pediatric COVID-19 vaccines might cause MIS-C, Dr. Robinson says data suggest this is rarely, if ever, the case, and that vaccines actually prevent the syndrome. She says further studies will be needed to assess MIS-C risk following reinfection with SARS-CoV-2. “I am an optimistic person, and it is my hope that MIS-C following reinfection is rare,” she said. “If this is the case, perhaps we will see very few cases once almost all children have been immunized and/or had SARS-CoV-2 infection.”  
 

‘Differences across countries’

Adrienne Randolph, MD, a pediatrician at Harvard Medical School, Boston, and senior author of a large case series of patients with MIS-C, said that the Canadian study is valuable because it includes children from three countries. “It’s very interesting that there are differences across countries,” she said. “The patients in Iran had the highest percentage (58.7%) going into the ICU, whereas Costa Rica had the lowest percentage (9.2%), and the percentage going to the ICU in Canada (34.7%) was less than the percentages we see in the U.S. – which is pretty consistently about 60% to 70% of MIS-C patients going into the ICU.” Dr. Randolph was not involved in the current study.

Reasons for differences in the rates of ICU visits will be important to explore in the effort to standardize diagnostic criteria, stratification of severity, and recommendations for treatment of MIS-C, said Dr. Randolph.

“What is consistent is that the younger kids, zero to 5 years, in general are less ill,” she said. “That’s been consistent across multiple countries.” It’s unclear whether the cause of this difference is that parents observe younger patients more closely than they do teenagers, or whether other aspects of adolescence, such as prevalence of obesity and attendant inflammation, are at work, said Dr. Randolph.

What is also unclear is why hospitalized patients with MIS-C had higher percentages of ICU admission in the latter part of the study period, compared with the earlier period. “Did the patients change, or did practice change as we got to understand the disease process?” asked Dr. Randolph. “It could be that they got better at the diagnosis and were weeding out some of the patients who they realized didn’t need to be hospitalized. At the very beginning, we had a very low threshold to admit patients, because we didn’t know, and then, over time, people understood what was going on and felt more comfortable monitoring them as outpatients.”

This study was partially funded by a Janeway Foundation Research Grant to support data collection. Dr. Robinson disclosed no conflicts of interest. Dr. Randolph reported receiving royalties from UpToDate and personal fees from the La Jolla Pharmaceutical Company.

Adrienne Randolph, MD, a pediatrician at Harvard Medical School, Boston, and senior author of a large case series of patients with MIS-C, said that the Canadian study is valuable because it includes children from three countries. “It’s very interesting that there are differences across countries,” she said. “The patients in Iran had the highest percentage (58.7%) going into the ICU, whereas Costa Rica had the lowest percentage (9.2%), and the percentage going to the ICU in Canada (34.7%) was less than the percentages we see in the U.S. – which is pretty consistently about 60% to 70% of MIS-C patients going into the ICU.” Dr. Randolph was not involved in the current study.

Reasons for differences in the rates of ICU visits will be important to explore in the effort to standardize diagnostic criteria, stratification of severity, and recommendations for treatment of MIS-C, said Dr. Randolph.

“What is consistent is that the younger kids, zero to 5 years, in general are less ill,” she said. “That’s been consistent across multiple countries.” It’s unclear whether the cause of this difference is that parents observe younger patients more closely than they do teenagers, or whether other aspects of adolescence, such as prevalence of obesity and attendant inflammation, are at work, said Dr. Randolph.

What is also unclear is why hospitalized patients with MIS-C had higher percentages of ICU admission in the latter part of the study period, compared with the earlier period. “Did the patients change, or did practice change as we got to understand the disease process?” asked Dr. Randolph. “It could be that they got better at the diagnosis and were weeding out some of the patients who they realized didn’t need to be hospitalized. At the very beginning, we had a very low threshold to admit patients, because we didn’t know, and then, over time, people understood what was going on and felt more comfortable monitoring them as outpatients.”

This study was partially funded by a Janeway Foundation Research Grant to support data collection. Dr. Robinson disclosed no conflicts of interest. Dr. Randolph reported receiving royalties from UpToDate and personal fees from the La Jolla Pharmaceutical Company.

The U.S. Centers for Disease Control and Prevention has issued a health alert regarding severe hepatitis in young children after several cases have been reported in Alabama. Public health officials in the United Kingdom are also investigating more than 100 cases. While the source of the infections is unknown, “a possible association between pediatric hepatitis and adenovirus infection is currently under investigation,” according to the CDC alert.

Internationally, 108 cases have been reported in the United Kingdom, with 79 cases occurring in England. There are three documented cases in Spain, and similar cases are being reported in Denmark and the Netherlands, according to an article in Science. In the United Kingdom, cases have been reported in children up to 16 years old, but most affected children are between 2 and 5 years old. Eight children in the United Kingdom have required liver transplants.

On April 14, the CDC said that nine cases have been recorded in Alabama since the fall of 2021. All of these cases have been in children between 1 and 6 years old, and two children have needed liver transplants. Two additional cases have been reported in North Carolina, according to Stat News, and both children have since recovered.

Hepatitis A, B, C, D, and E viruses—common causes of hepatitis—have been ruled out in the U.K. and Spanish cases. More than three-fourths (77%) of the children sickened in the United Kingdom and all nine cases in Alabama have tested positive for a form of the adenovirus. While adenovirus can cause hepatitis in children, it is usually in those who are immunocompromised.

The CDC health alert advises clinicians who have cases of unexplained hepatitis in children to test for adenovirus and report these cases to the CDC as well as state public health authorities. The agency recommends nucleic acid amplification testing to detect adenovirus using respiratory swabs, stool samples or rectal swabs, or blood.

Officials are exploring whether these cases are linked to a version of the virus called adenovirus 41, which is associated with gut inflammation. The most recent case in Alabama was reported in February, and five of the nine children in the state with these puzzling cases of hepatitis have tested positive for adenovirus 41.

There have yet to be any links among the cases in Alabama or North Carolina, and investigators in the United Kingdom have also not found any connections in their cases, STAT News reports.

“CDC is working with state health departments to see if there are additional U.S. cases and what may be causing these cases,” said Kristen Nordlund, a CDC spokesperson, in a statement to STAT News. “At this time, adenovirus may be the cause for these, but investigators are still learning more – including ruling out the more common causes of hepatitis.”

Looking for other explanations

None of the children in the United States with hepatitis had COVID-19, but a few children in the United Kingdom have tested positive for the virus; none of these children have received the COVID-19 vaccine.

While the U.K. Health Security Agency says their investigation “continues to point toward a link to adenovirus infection,” they are also considering other contributing factors such as an environmental cause or COVID-19.

“COVID has been consistently shown to increase liver test numbers,” Nancy Reau, MD, the section chief of hepatology at Rush University in Chicago, said in an interview with this news organization. “It has been shown to cause other organ involvement besides just pulmonary symptoms and respiratory failure. As this virus evolves, it might be that in children, it is more able to present as hepatitis.”

Giving the probiotic supplement Lactobacillus rhamnosus GG (LGG) to high-risk infants in the first 6 months of life is not effective in lessening incidence of eczema, asthma, or rhinitis in later childhood, researchers have found.

The researchers, led by Michael D. Cabana, MD, MPH, with the Children’s Hospital of Montefiore, New York, said they cannot support its use in this population of children at high risk for allergic disease. Findings were published in Pediatrics.

Jonathan Spergel, MD, PhD, chief of the allergy program at Children’s Hospital of Philadelphia, who was not part of the study, said the “small, but very interesting study adds to the literature indicating that allergy prevention needs to be a multifactorial approach and simply adding LGG in a select population makes no difference.”

He noted that the study of probiotics for allergic conditions is complex as it depends on many factors, such as the child’s environment, including exposure to pets and pollution, and whether the child was delivered vaginally or by cesarean section.

Study builds on previous work

The new study builds on the same researchers’ randomized, double-masked, parallel-arm, controlled Trial of Infant Probiotic Supplementation (TIPS). That study investigated whether daily administration of LGG in the first 6 months to children at high risk for allergic disease because of asthma in a parent, could decrease their cumulative incidence of eczema. Investigators found LGG had no effect.

These additional results included participants at least 7 years old and also included physician-diagnosed asthma and physician-diagnosed rhinitis as secondary outcomes.

Retention rate over the 7-year follow-up was 56%; 49 (53%) of 92 in the intervention group and 54 (59%) of 92 in the control group.

The researchers performed modified intention-to-treat analyses with all children who received treatment in the study arm to which they had been randomized.

Eczema was diagnosed in 78 participants, asthma in 32, and rhinitis in 15. Incidence of eczema was high in infancy, but low thereafter. Incidence rates for asthma and rhinitis were constant throughout childhood.

The researchers used modeling to compare the incidence of each outcome between the intervention and control groups, adjusting for mode of delivery and how long a child was breastfed.

Cesarean delivery was linked to a greater incidence of rhinitis, with a hazard ratio of 3.33 (95% confidence interval, 1.21-9.21).

Finding the right strain

Heather Cassell, MD, a pediatric allergist and immunologist at University of Arizona, Tucson, who was not part of the study, said in an interview that many researchers, including those at her institution, are trying to find which strain of probiotic might be beneficial in lowering risk for allergic disease.

Though it appears LGG doesn’t have an effect, she said, another strain might be successful and this helps zero in on the right one.

The TIPS trial showed that there were no significant side effects from giving LGG early, which is good information to have as the search resumes for the right strain, she said.

“We know that there’s probably some immune dysregulation in kids with asthma, eczema, other allergies, but we don’t fully know the extent of it,” she said, adding that it may be that skin flora or respiratory flora and microbiomes in other parts of the body play a role.

“We don’t have bacteria just in our guts,” she noted. “It may be a combination of strains or a combination of bacteria.”

The authors, Dr. Spergel, and Dr. Cassell reported no relevant financial relationships.

Photosensitivity due to doxycycline

As the patient’s rash presented in sun-exposed areas with both skin and nail changes, our patient was diagnosed with a phototoxic reaction to doxycycline, the oral antibiotic used to treat his acne.

Photosensitive cutaneous drug eruptions are reactions that occur after exposure to a medication and subsequent exposure to UV radiation or visible light. Reactions can be classified into two ways based on their mechanism of action: phototoxic or photoallergic.¹ Phototoxic reactions are more common and are a result of direct keratinocyte damage and cellular necrosis. Many classes of medications may cause this adverse effect, but the tetracycline class of antibiotics is a common culprit.² Photoallergic reactions are less common and are a result of a type IV immune reaction to the offending agent.¹

Phototoxic reactions generally present shortly after sun or UV exposure with a photo-distributed eruption pattern.³ Commonly involved areas include the face, the neck, and the extensor surfaces of extremities, with sparing of relatively protected skin such as the upper eyelids and the skin folds.² Erythema may initially develop in the exposed skin areas, followed by appearance of edema, vesicles, or bullae.^1-3 The eruption may be painful and itchy, with some patients reporting severe pain.³

Courtesy Dr. Catalina Matiz

Doxycycline phototoxicity may also cause onycholysis of the nails.² The reaction is dose dependent, with higher doses of medication leading to a higher likelihood of symptoms.^1,2 It is also more prevalent in patients with Fitzpatrick skin type I and II. The usual UVA wavelength required to induce this reaction appears to be in the 320-400 nm range of the UV spectrum.⁴ By contrast, photoallergic reactions are dose independent, and require a sensitization period prior to the eruption.¹ An eczematous eruption is most commonly seen with photoallergic reactions.³

Treatment of drug-induced photosensitivity reactions requires proper identification of the diagnosis and the offending agent, followed by cessation of the medication. If cessation is not possible, then lowering the dose can help to minimize worsening of the condition. However, for photoallergic reactions, the reaction is dose independent so switching to another tolerated agent is likely required. For persistent symptoms following medication withdrawal, topical or systemic steroids and oral antihistamine can help with symptom management.¹ For patients with photo-onycholysis, treatment involves stopping the medication and waiting for the intact nail plate to grow.

Dermatomyositis

Dermatomyositis is an autoimmune condition that presents with skin lesions as well as systemic findings such as myositis. The cutaneous findings are variable, but pathognomonic findings include Gottron papules of the hands, Gottron’s sign on the elbows, knees, and ankles, and the heliotrope rash of the face. Eighty percent of patients have myopathy presenting as muscle weakness, and commonly have elevated creatine kinase, aspartate transaminase, and alanine transaminase values.⁵ Diagnosis may be confirmed through skin or muscle biopsy, though antibody studies can also play a helpful role in diagnosis. Treatment is generally with oral corticosteroids or other immunosuppressants as well as sun protection.⁶ The rash seen in our patient could have been seen in patients with dermatomyositis, though it was not in the typical location on the knuckles (Gottron papules) as it also affected the lateral sides of the fingers.

Systemic lupus erythematosus

Systemic lupus erythematosus (SLE) is an autoimmune condition characterized by systemic and cutaneous manifestations. Systemic symptoms may include weight loss, fever, fatigue, arthralgia, or arthritis; patients are at risk of renal, cardiovascular, pulmonary, and neurologic complications of SLE.⁷ The most common cutaneous finding is malar rash, though there are myriad dermatologic manifestations that can occur associated with photosensitivity. Diagnosis is made based on history, physical, and laboratory testing. Treatment options include NSAIDs, oral glucocorticoids, antimalarial drugs, and immunosuppressants.⁷ Though our patient exhibited photosensitivity, he had none of the systemic findings associated with SLE, making this diagnosis unlikely.

Allergic contact dermatitis

Allergic contact dermatitis (ACD) is a type IV hypersensitivity reaction, and may present as acute, subacute, or chronic dermatitis. The clinical findings vary based on chronicity. Acute ACD presents as pruritic erythematous papules and vesicles or bullae, similar to how it occurred in our patient, though our patient’s lesions were more tender than pruritic. Chronic ACD presents with erythematous lesions with pruritis, lichenification, scaling, and/or fissuring. Observing shapes or sharp demarcation of lesions may help with diagnosis. Patch testing is also useful in the diagnosis of ACD.

Treatment generally involves avoiding the offending agent with topical corticosteroids for symptom management.⁸

Polymorphous light eruption

Polymorphous light eruption (PLE) is a delayed, type IV hypersensitivity reaction to UV-induced antigens, though these antigens are unknown. PLE presents hours to days following solar or UV exposure and presents only in sun-exposed areas. Itching and burning are always present, but lesion morphology varies from erythema and papules to vesico-papules and blisters. Notably, PLE must be distinguished from drug photosensitivity through history. Treatment generally involves symptom management with topical steroids and sun protective measures for prevention.⁹ While PLE may present similarly to drug photosensitivity reactions, our patient’s use of a known phototoxic agent makes PLE a less likely diagnosis.

Photosensitivity due to doxycycline

As the patient’s rash presented in sun-exposed areas with both skin and nail changes, our patient was diagnosed with a phototoxic reaction to doxycycline, the oral antibiotic used to treat his acne.

Photosensitive cutaneous drug eruptions are reactions that occur after exposure to a medication and subsequent exposure to UV radiation or visible light. Reactions can be classified into two ways based on their mechanism of action: phototoxic or photoallergic.¹ Phototoxic reactions are more common and are a result of direct keratinocyte damage and cellular necrosis. Many classes of medications may cause this adverse effect, but the tetracycline class of antibiotics is a common culprit.² Photoallergic reactions are less common and are a result of a type IV immune reaction to the offending agent.¹

Phototoxic reactions generally present shortly after sun or UV exposure with a photo-distributed eruption pattern.³ Commonly involved areas include the face, the neck, and the extensor surfaces of extremities, with sparing of relatively protected skin such as the upper eyelids and the skin folds.² Erythema may initially develop in the exposed skin areas, followed by appearance of edema, vesicles, or bullae.^1-3 The eruption may be painful and itchy, with some patients reporting severe pain.³

Doxycycline phototoxicity may also cause onycholysis of the nails.² The reaction is dose dependent, with higher doses of medication leading to a higher likelihood of symptoms.^1,2 It is also more prevalent in patients with Fitzpatrick skin type I and II. The usual UVA wavelength required to induce this reaction appears to be in the 320-400 nm range of the UV spectrum.⁴ By contrast, photoallergic reactions are dose independent, and require a sensitization period prior to the eruption.¹ An eczematous eruption is most commonly seen with photoallergic reactions.³

Treatment of drug-induced photosensitivity reactions requires proper identification of the diagnosis and the offending agent, followed by cessation of the medication. If cessation is not possible, then lowering the dose can help to minimize worsening of the condition. However, for photoallergic reactions, the reaction is dose independent so switching to another tolerated agent is likely required. For persistent symptoms following medication withdrawal, topical or systemic steroids and oral antihistamine can help with symptom management.¹ For patients with photo-onycholysis, treatment involves stopping the medication and waiting for the intact nail plate to grow.

Dermatomyositis

Dermatomyositis is an autoimmune condition that presents with skin lesions as well as systemic findings such as myositis. The cutaneous findings are variable, but pathognomonic findings include Gottron papules of the hands, Gottron’s sign on the elbows, knees, and ankles, and the heliotrope rash of the face. Eighty percent of patients have myopathy presenting as muscle weakness, and commonly have elevated creatine kinase, aspartate transaminase, and alanine transaminase values.⁵ Diagnosis may be confirmed through skin or muscle biopsy, though antibody studies can also play a helpful role in diagnosis. Treatment is generally with oral corticosteroids or other immunosuppressants as well as sun protection.⁶ The rash seen in our patient could have been seen in patients with dermatomyositis, though it was not in the typical location on the knuckles (Gottron papules) as it also affected the lateral sides of the fingers.

Systemic lupus erythematosus

Systemic lupus erythematosus (SLE) is an autoimmune condition characterized by systemic and cutaneous manifestations. Systemic symptoms may include weight loss, fever, fatigue, arthralgia, or arthritis; patients are at risk of renal, cardiovascular, pulmonary, and neurologic complications of SLE.⁷ The most common cutaneous finding is malar rash, though there are myriad dermatologic manifestations that can occur associated with photosensitivity. Diagnosis is made based on history, physical, and laboratory testing. Treatment options include NSAIDs, oral glucocorticoids, antimalarial drugs, and immunosuppressants.⁷ Though our patient exhibited photosensitivity, he had none of the systemic findings associated with SLE, making this diagnosis unlikely.

Allergic contact dermatitis

Allergic contact dermatitis (ACD) is a type IV hypersensitivity reaction, and may present as acute, subacute, or chronic dermatitis. The clinical findings vary based on chronicity. Acute ACD presents as pruritic erythematous papules and vesicles or bullae, similar to how it occurred in our patient, though our patient’s lesions were more tender than pruritic. Chronic ACD presents with erythematous lesions with pruritis, lichenification, scaling, and/or fissuring. Observing shapes or sharp demarcation of lesions may help with diagnosis. Patch testing is also useful in the diagnosis of ACD.

Treatment generally involves avoiding the offending agent with topical corticosteroids for symptom management.⁸

Polymorphous light eruption

Polymorphous light eruption (PLE) is a delayed, type IV hypersensitivity reaction to UV-induced antigens, though these antigens are unknown. PLE presents hours to days following solar or UV exposure and presents only in sun-exposed areas. Itching and burning are always present, but lesion morphology varies from erythema and papules to vesico-papules and blisters. Notably, PLE must be distinguished from drug photosensitivity through history. Treatment generally involves symptom management with topical steroids and sun protective measures for prevention.⁹ While PLE may present similarly to drug photosensitivity reactions, our patient’s use of a known phototoxic agent makes PLE a less likely diagnosis.

The prevalence of attention-deficit/hyperactivity disorder is difficult to evaluate, and the diagnosis is based primarily on clinical criteria. In 2008, a French study estimated the prevalence to be between 3.5% and 5.6%, but the study’s design was questionable.

Treatment of this disorder consists first and foremost of educational, social, and psychotherapeutic management. Only if such treatment fails is methylphenidate (MPH), the only drug that has been approved in France for this indication, to be considered, according to the recommendations.

The drug’s short-term efficacy has been proven, but it has not shown any effect on the long-term risks for academic failure, delinquency, and drug addiction associated with ADHD. In contrast, its adverse effects are numerous. Cases of nervousness, sleep disorders, headaches, weight loss, risk for aggravation of psychiatric conditions, and progression to violent or suicidal behavior have all been documented extensively, as well as cases of cardiovascular and cerebrovascular disease. Moreover, MPH is classified as a narcotic.
 

Inappropriate prescribing conditions

A study that appeared in the French journal of neuropsychiatry in minors, Neuropsychiatrie de l’Enfance et de l’Adolescence, investigated the prescribing procedures for this drug in France. Researchers examined Social Security data for 144,509 patients between the ages of 0 and 17 years who had received at least one prescription between 2010 and 2019. The researchers made the following observations about prescribing patterns and usage during this period:

• New MPH prescriptions increased by 56% per year, and the total number of annual prescriptions increased by 116%. In 3- to 17-year-olds, the prevalence was estimated at 0.61% to 0.75% of the pediatric population in 2019. Boys accounted for most of this consumption (82.5% to 80.8% over this period).
• In 2011, the median duration of consumption by children 6 years of age and older was 5.5 years. For 25% of those children, it was more than 8 years.
• Contrary to the labeling, some prescriptions were written for children younger than 6 years.
• Twenty-five percent of initial prescriptions and 50% of annual renewals were not written by a hospital specialist, in violation of the regulatory requirements in effect until Sept. 13, 2021. On that date, the French National Authority for Health (HAS) decided that initial hospital prescription of MPH should end.
• Eighty-four percent of children did not have any medical consultations at the prescribing hospital department in the 13 months after starting MPH. While the prevalence of ADHD has more than doubled, the number of consultations at specialist French medical, psychological, and educational centers for minors (CMPPs) is now less than a fourth of what it was – a drop from 4.1% to 0.8%.
• The prescribing of MPH is not always associated with an ADHD diagnosis, even though ADHD is its only indication.
• Of children and adolescents who use MPH, 22.8% received one or more other psychotropic drugs in the year following the initial prescription, including the following: neuroleptics (64.5%), anxiolytics (35.5%), antidepressants (16.2%), antiepileptics (11%), hypnotics (4.8%), and antiparkinsonian drugs (3%). “These co-prescriptions are often way off-label and are not within HAS recommendations,” according to the authors.
• For the youngest children in school classes (those born in December rather than in January), between 2010 and 2019, there was on average a 54% increased risk of being medicated.
• In 2019, 21.7% of children who received MPH lived in families with Universal Health Coverage or a similar plan. Yet, according to the French National Institute of Statistics and Economic Studies, only 7.8% of the French population had this type of assistance.

A minority of practitioners

The authors of this article state that “the distribution of consumption suggests a predominant role of a minority of practitioners and hospital departments in the prescription of methylphenidate.” They note that “in European countries and in North America, the prescription rate of psychotropic drugs for ADHD has stabilized or shown a clear trend toward stabilization since 2008. The same cannot be said for France, where this rate is continuously increasing; so much so that in 2019, it reached a higher level than in other European countries like Great Britain.” The reasons for this are disputed.

For a decade, the number of babies born with syphilis in the United States has surged, undeterred. Data released Apr. 12 by the Centers for Disease Control and Prevention shows just how dire the outbreak has become.

In 2012, 332 babies were born infected with the disease. In 2021, that number had climbed nearly sevenfold, to at least 2,268, according to preliminary estimates. And 166 of those babies died.

About 7% of babies diagnosed with syphilis in recent years have died; thousands of others born with the disease have faced problems that include brain and bone malformations, blindness, and organ damage.

For public health officials, the situation is all the more heartbreaking, considering that congenital syphilis rates reached near-historic modern lows from 2000 to 2012 amid ambitious prevention and education efforts. By 2020, following a sharp erosion in funding and attention, the nationwide case rate was more than seven times that of 2012.

“The really depressing thing about it is we had this thing virtually eradicated back in the year 2000,” said William Andrews, a public information officer for Oklahoma’s sexual health and harm reduction service. “Now it’s back with a vengeance. We are really trying to get the message out that sexual health is health. It’s nothing to be ashamed of.”

Even as caseloads soar, the CDC budget for STD prevention – the primary funding source for most public health departments – has been largely stagnant for two decades, its purchasing power dragged even lower by inflation.

The CDC report on STD trends provides official data on congenital syphilis cases for 2020, as well as preliminary case counts for 2021 that are expected to increase. CDC data shows that congenital syphilis rates in 2020 continued to climb in already overwhelmed states like Texas, California, and Nevada and that the disease is now present in almost every state in the nation. All but three states – Maine, New Hampshire, and Vermont – reported congenital syphilis cases in 2020.

From 2011 to 2020, congenital syphilis resulted in 633 documented stillbirths and infant deaths, according to the new CDC data.

Preventing congenital syphilis – the term used when syphilis is transferred to a fetus in utero – is from a medical standpoint exceedingly simple: If a pregnant woman is diagnosed at least a month before giving birth, just a few shots of penicillin have a near-perfect cure rate for mother and baby. But funding cuts and competing priorities in the nation’s fragmented public health care system have vastly narrowed access to such services.

The reasons pregnant people with syphilis go undiagnosed or untreated vary geographically, according to data collected by states and analyzed by the CDC.

In Western states, the largest share of cases involve women who have received little to no prenatal care and aren’t tested for syphilis until they give birth. Many have substance use disorders, primarily related to methamphetamines. “They’ve felt a lot of judgment and stigma by the medical community,” said Stephanie Pierce, MD, a maternal fetal medicine specialist at the University of Oklahoma, Oklahoma City, who runs a clinic for women with high-risk pregnancies.

In Southern states, a CDC study of 2018 data found that the largest share of congenital syphilis cases were among women who had been tested and diagnosed but hadn’t received treatment. That year, among Black moms who gave birth to a baby with syphilis, 37% had not been treated adequately even though they’d received a timely diagnosis. Among white moms, that number was 24%. Longstanding racism in medical care, poverty, transportation issues, poorly funded public health departments, and crowded clinics whose employees are too overworked to follow up with patients all contribute to the problem, according to infectious disease experts.

Doctors are also noticing a growing number of women who are treated for syphilis but reinfected during pregnancy. Amid rising cases and stagnant resources, some states have focused disease investigations on pregnant women of childbearing age; they can no longer prioritize treating sexual partners who are also infected.

Eric McGrath, MD, a pediatric infectious disease specialist at Wayne State University, Detroit, said that he’d seen several newborns in recent years whose mothers had been treated for syphilis but then were re-exposed during pregnancy by partners who hadn’t been treated.

Treating a newborn baby for syphilis isn’t trivial. Penicillin carries little risk, but delivering it to a baby often involves a lumbar puncture and other painful procedures. And treatment typically means keeping the baby in the hospital for 10 days, interrupting an important time for family bonding.

Dr. McGrath has seen a couple of babies in his career who weren’t diagnosed or treated at birth and later came to him with full-blown syphilis complications, including full-body rashes and inflamed livers. It was an awful experience he doesn’t want to repeat. The preferred course, he said, is to spare the baby the ordeal and treat parents early in the pregnancy.

But in some places, providers aren’t routinely testing for syphilis. Although most states mandate testing at some point during pregnancy, as of last year just 14 required it for everyone in the third trimester. The CDC recommends third-trimester testing in areas with high rates of syphilis, a growing share of the United States.

After Arizona declared a statewide outbreak in 2018, state health officials wanted to know whether widespread testing in the third trimester could have prevented infections. Looking at 18 months of data, analysts found that nearly three-quarters of the more than 200 pregnant women diagnosed with syphilis in 2017 and the first half of 2018 got treatment. That left 57 babies born with syphilis, nine of whom died. The analysts estimated that a third of the infections could have been prevented with testing in the third trimester.

Based on the numbers they saw in those 18 months, officials estimated that screening all women on Medicaid in the third trimester would cost the state $113,300 annually, and that treating all cases of syphilis that screening would catch could be done for just $113. Factoring in the hospitalization costs for infected infants, the officials concluded the additional testing would save the state money.

And yet prevention money has been hard to come by. Taking inflation into account, CDC prevention funding for STDs has fallen 41% since 2003, according to an analysis by the National Coalition of STD Directors. That’s even as cases have risen, leaving public health departments saddled with more work and far less money.

Janine Waters, STD program manager for the state of New Mexico, has watched the unraveling. When Ms. Waters started her career more than 20 years ago, she and her colleagues followed up on every case of chlamydia, gonorrhea, and syphilis reported, not only making sure that people got treatment but also getting in touch with their sexual partners, with the aim of stopping the spread of infection. In a 2019 interview with Kaiser Health News, she said her team was struggling to keep up with syphilis alone, even as they registered with dread congenital syphilis cases surging in neighboring Texas and Arizona.

By 2020, New Mexico had the highest rate of congenital syphilis in the country.

The COVID-19 pandemic drained the remaining resources. Half of health departments across the country discontinued STD fieldwork altogether, diverting their resources to COVID. In California, which for years has struggled with high rates of congenital syphilis, three-quarters of local health departments dispatched more than half of their STD staffers to work on COVID.

As the pandemic ebbs – at least in the short term – many public health departments are turning their attention back to syphilis and other diseases. And they are doing it with reinforcements. Although the Biden administration’s proposed STD prevention budget for 2023 remains flat, the American Rescue Plan Act included $200 million to help health departments boost contact tracing and surveillance for covid and other infectious diseases. Many departments are funneling that money toward STDs.

The money is an infusion that state health officials say will make a difference. But when taking inflation into account, it essentially brings STD prevention funding back to what it was in 2003, said Stephanie Arnold Pang of the National Coalition of STD Directors. And the American Rescue Plan money doesn’t cover some aspects of STD prevention, including clinical services.

The coalition wants to revive dedicated STD clinics, where people can drop in for testing and treatment at little to no cost. Advocates say that would fill a void that has plagued treatment efforts since public clinics closed en masse in the wake of the 2008 recession.

Texas, battling its own pervasive outbreak, will use its share of American Rescue Plan money to fill 94 new positions focused on various aspects of STD prevention. Those hires will bolster a range of measures the state put in place before the pandemic, including an updated data system to track infections, review boards in major cities that examine what went wrong for every case of congenital syphilis, and a requirement that providers test for syphilis during the third trimester of pregnancy. The suite of interventions seems to be working, but it could be a while before cases go down, said Amy Carter, the state’s congenital syphilis coordinator.

“The growth didn’t happen overnight,” Ms. Carter said. “So our prevention efforts aren’t going to have a direct impact overnight either.”

Longstanding racism in medical care, poverty, transportation issues, poorly funded public health departments, and crowded clinics whose employees are too overworked to follow up with patients all contribute to the problem, according to infectious disease experts.

Doctors are also noticing a growing number of women who are treated for syphilis but reinfected during pregnancy. Amid rising cases and stagnant resources, some states have focused disease investigations on pregnant women of childbearing age; they can no longer prioritize treating sexual partners who are also infected.

Eric McGrath, MD, a pediatric infectious disease specialist at Wayne State University, Detroit, said that he’d seen several newborns in recent years whose mothers had been treated for syphilis but then were re-exposed during pregnancy by partners who hadn’t been treated.

Treating a newborn baby for syphilis isn’t trivial. Penicillin carries little risk, but delivering it to a baby often involves a lumbar puncture and other painful procedures. And treatment typically means keeping the baby in the hospital for 10 days, interrupting an important time for family bonding.

Dr. McGrath has seen a couple of babies in his career who weren’t diagnosed or treated at birth and later came to him with full-blown syphilis complications, including full-body rashes and inflamed livers. It was an awful experience he doesn’t want to repeat. The preferred course, he said, is to spare the baby the ordeal and treat parents early in the pregnancy.

But in some places, providers aren’t routinely testing for syphilis. Although most states mandate testing at some point during pregnancy, as of last year just 14 required it for everyone in the third trimester. The CDC recommends third-trimester testing in areas with high rates of syphilis, a growing share of the United States.

After Arizona declared a statewide outbreak in 2018, state health officials wanted to know whether widespread testing in the third trimester could have prevented infections. Looking at 18 months of data, analysts found that nearly three-quarters of the more than 200 pregnant women diagnosed with syphilis in 2017 and the first half of 2018 got treatment. That left 57 babies born with syphilis, nine of whom died. The analysts estimated that a third of the infections could have been prevented with testing in the third trimester.

Based on the numbers they saw in those 18 months, officials estimated that screening all women on Medicaid in the third trimester would cost the state $113,300 annually, and that treating all cases of syphilis that screening would catch could be done for just $113. Factoring in the hospitalization costs for infected infants, the officials concluded the additional testing would save the state money.

And yet prevention money has been hard to come by. Taking inflation into account, CDC prevention funding for STDs has fallen 41% since 2003, according to an analysis by the National Coalition of STD Directors. That’s even as cases have risen, leaving public health departments saddled with more work and far less money.

Janine Waters, STD program manager for the state of New Mexico, has watched the unraveling. When Ms. Waters started her career more than 20 years ago, she and her colleagues followed up on every case of chlamydia, gonorrhea, and syphilis reported, not only making sure that people got treatment but also getting in touch with their sexual partners, with the aim of stopping the spread of infection. In a 2019 interview with Kaiser Health News, she said her team was struggling to keep up with syphilis alone, even as they registered with dread congenital syphilis cases surging in neighboring Texas and Arizona.

By 2020, New Mexico had the highest rate of congenital syphilis in the country.

The COVID-19 pandemic drained the remaining resources. Half of health departments across the country discontinued STD fieldwork altogether, diverting their resources to COVID. In California, which for years has struggled with high rates of congenital syphilis, three-quarters of local health departments dispatched more than half of their STD staffers to work on COVID.

As the pandemic ebbs – at least in the short term – many public health departments are turning their attention back to syphilis and other diseases. And they are doing it with reinforcements. Although the Biden administration’s proposed STD prevention budget for 2023 remains flat, the American Rescue Plan Act included $200 million to help health departments boost contact tracing and surveillance for covid and other infectious diseases. Many departments are funneling that money toward STDs.

The money is an infusion that state health officials say will make a difference. But when taking inflation into account, it essentially brings STD prevention funding back to what it was in 2003, said Stephanie Arnold Pang of the National Coalition of STD Directors. And the American Rescue Plan money doesn’t cover some aspects of STD prevention, including clinical services.

The coalition wants to revive dedicated STD clinics, where people can drop in for testing and treatment at little to no cost. Advocates say that would fill a void that has plagued treatment efforts since public clinics closed en masse in the wake of the 2008 recession.

Texas, battling its own pervasive outbreak, will use its share of American Rescue Plan money to fill 94 new positions focused on various aspects of STD prevention. Those hires will bolster a range of measures the state put in place before the pandemic, including an updated data system to track infections, review boards in major cities that examine what went wrong for every case of congenital syphilis, and a requirement that providers test for syphilis during the third trimester of pregnancy. The suite of interventions seems to be working, but it could be a while before cases go down, said Amy Carter, the state’s congenital syphilis coordinator.

“The growth didn’t happen overnight,” Ms. Carter said. “So our prevention efforts aren’t going to have a direct impact overnight either.”

For a decade, the number of babies born with syphilis in the United States has surged, undeterred. Data released Apr. 12 by the Centers for Disease Control and Prevention shows just how dire the outbreak has become.

In 2012, 332 babies were born infected with the disease. In 2021, that number had climbed nearly sevenfold, to at least 2,268, according to preliminary estimates. And 166 of those babies died.

About 7% of babies diagnosed with syphilis in recent years have died; thousands of others born with the disease have faced problems that include brain and bone malformations, blindness, and organ damage.

For public health officials, the situation is all the more heartbreaking, considering that congenital syphilis rates reached near-historic modern lows from 2000 to 2012 amid ambitious prevention and education efforts. By 2020, following a sharp erosion in funding and attention, the nationwide case rate was more than seven times that of 2012.

“The really depressing thing about it is we had this thing virtually eradicated back in the year 2000,” said William Andrews, a public information officer for Oklahoma’s sexual health and harm reduction service. “Now it’s back with a vengeance. We are really trying to get the message out that sexual health is health. It’s nothing to be ashamed of.”

Even as caseloads soar, the CDC budget for STD prevention – the primary funding source for most public health departments – has been largely stagnant for two decades, its purchasing power dragged even lower by inflation.

The CDC report on STD trends provides official data on congenital syphilis cases for 2020, as well as preliminary case counts for 2021 that are expected to increase. CDC data shows that congenital syphilis rates in 2020 continued to climb in already overwhelmed states like Texas, California, and Nevada and that the disease is now present in almost every state in the nation. All but three states – Maine, New Hampshire, and Vermont – reported congenital syphilis cases in 2020.

From 2011 to 2020, congenital syphilis resulted in 633 documented stillbirths and infant deaths, according to the new CDC data.

Preventing congenital syphilis – the term used when syphilis is transferred to a fetus in utero – is from a medical standpoint exceedingly simple: If a pregnant woman is diagnosed at least a month before giving birth, just a few shots of penicillin have a near-perfect cure rate for mother and baby. But funding cuts and competing priorities in the nation’s fragmented public health care system have vastly narrowed access to such services.

The reasons pregnant people with syphilis go undiagnosed or untreated vary geographically, according to data collected by states and analyzed by the CDC.

In Western states, the largest share of cases involve women who have received little to no prenatal care and aren’t tested for syphilis until they give birth. Many have substance use disorders, primarily related to methamphetamines. “They’ve felt a lot of judgment and stigma by the medical community,” said Stephanie Pierce, MD, a maternal fetal medicine specialist at the University of Oklahoma, Oklahoma City, who runs a clinic for women with high-risk pregnancies.

In Southern states, a CDC study of 2018 data found that the largest share of congenital syphilis cases were among women who had been tested and diagnosed but hadn’t received treatment. That year, among Black moms who gave birth to a baby with syphilis, 37% had not been treated adequately even though they’d received a timely diagnosis. Among white moms, that number was 24%. Longstanding racism in medical care, poverty, transportation issues, poorly funded public health departments, and crowded clinics whose employees are too overworked to follow up with patients all contribute to the problem, according to infectious disease experts.
