The Diagnosis: Dominant Dystrophic Epidermolysis Bullosa

Blisters in a neonate may be caused by infectious, traumatic, autoimmune, or congenital etiologies. Biopsy findings correlated with clinical findings usually can establish a prompt diagnosis when the clinical diagnosis is uncertain. Direct immunofluorescence (DIF) as well as indirect immunofluorescence studies are useful when autoimmune blistering disease or congenital or heritable disorders of skin fragility are in the differential diagnosis. Many genetic abnormalities of skin fragility are associated with marked morbidity and mortality, and prompt diagnosis is essential to provide proper care. Our patient’s parents had no history of skin disorders, and there was no known family history of blistering disease or traumatic birth. A heritable disorder of skin fragility was still a top consideration because of the extensive blistering in the absence of any other symptoms.

Although dystrophic epidermolysis bullosa (DEB) is an uncommon cause of skin fragility in neonates, our patient’s presentation was typical because of the extensive blistering and increased fragility of the skin at pressure points. Dystrophic epidermolysis bullosa has both dominant and recessive presentations that span a spectrum from mild and focal skin blistering to extensive blistering with esophageal involvement.¹ Early diagnosis and treatment can mitigate potential failure to thrive or premature death. Inherited mutations in the type VII collagen gene, COL7A1, are causative.² Dominant DEB may be associated with dental caries, swallowing problems secondary to esophageal scarring, and constipation, as well as dystrophic or absent nails. Immunomapping studies of the skin often reveal type VII collagen cytoplasmic granules in the epidermis and weaker reaction in the roof of the subepidermal separation (quiz image).³ Abnormalities in type VII collagen impact the production of anchoring fibrils. Blister cleavage occurs in the sublamina densa with type VII collagen staining evident on the blister roof (quiz image).⁴ Patients with severe generalized recessive DEB may have barely detectable type VII collagen. In our patient, the cytoplasmic staining and weak staining in the epidermal roof of the separation confirmed the clinical impression of dominant DEB.

Autoimmune blistering disease should be considered in the histologic differential diagnosis, but it usually is associated with obvious disease in the mother. Direct immunofluorescence of pemphigoid gestationis reveals linear deposition of C3 at the basement membrane zone, which also can be associated with IgG (Figure 1). Neonates receiving passive transfer of antibodies may develop annular erythema, vesicles, and even dyshidroticlike changes on the soles.⁵

Suction blisters are subepithelial.^6,7 When they occur in the neonatal period, they often are localized and are thought to be the result of vigorous sucking in utero.⁶ They quickly resolve without treatment and do not reveal abnormalities on DIF. If immunomapping is done for type VII collagen, it will be located at the floor of the suction blister (Figure 2).

Bullous pemphigoid is associated with deposition of linear IgG along the dermoepidermal junction—IgG4 is most common—and/or C3 (Figure 3). Direct immunofluorescence on split-skin biopsy reveals IgG on the epidermal side of the blister in bullous pemphigoid in contrast to epidermolysis bullosa acquisita, where the immune deposits are found on the dermal side of the split.^8,9 Linear IgA bullous disease is associated with IgA deposition (Figure 4).^10,11 Secretory IgA derived from breast milk can be causative.¹¹ Neonatal linear IgA bullous disease is a serious condition associated with marked mucosal involvement that can eventuate in respiratory compromise. Prompt recognition is important; breastfeeding must be stopped and supportive therapy must be provided.

Other types of vesicular or pustular eruptions in the newborn usually are easily diagnosed by their typical clinical presentation without biopsy. Erythema toxicum neonatorum usually presents within 1 to 2 days of birth. It is self-limited and often resembles acne, but it also occurs on the trunk and extremities. Transient neonatal pustular melanosis may be present at birth and predominantly is seen in newborns with skin of color. Lesions easily rupture and usually resolve within 1 to 2 days. Infectious causes of blistering often can be identified on clinical examination and confirmed by culture. Herpes simplex virus infection is associated with characteristic multinucleated giant cells as well as steel grey nuclei evident on routine histologic evaluation. Bullous impetigo reveals superficial acantholysis and will have negative findings on DIF.¹²

When a neonate presents with widespread blistering, both genetic disorders of skin fragility as well as passive transfer of antibodies from maternal autoimmune disease need to be considered. Direct immunofluorescence and indirect immunofluorescence immunomapping findings can be useful in clarifying the diagnosis when heritable disorders of skin fragility or autoimmune blistering diseases are a clinical consideration.

WASHINGTON – The LIBERTY AD open-label extension study of dupilumab is closing after 5 years with the small number of remaining patients showing stable and sustained improvements in skin lesions and pruritus and no new emergent side effects, Lisa Beck, MD, reported during a late-breaking session at the annual Revolutionizing Atopic Dermatitis conference.

Other recent research on the biologic has shown that it improves lesional skin barrier function and rapidly reduces the abundance of Staphylococcus aureus on lesional skin, Dr. Beck, professor of dermatology at the University of Rochester (N.Y.), said during another session at the meeting on long-term control of AD. Dr. Beck directs a laboratory at the University of Rochester Medical Center that focuses on understanding AD and is involved in the National Institute of Allergy and Infectious Diseases (NIAID)-funded Atopic Dermatitis Research Network (ADRN).

The LIBERTY AD open-label extension (OLE) study was a phase 3 trial of 2,677 adults with moderate to severe AD who had participated in previous dupilumab clinical trials and were treated with 300 mg dupilumab weekly or every other week. Concomitant treatments were permitted, including topical corticosteroids and topical calcineurin inhibitors. (The proportion of patients dosed on an every-other-week or weekly dosing schedule was not available.)

Of 334 patients (12.5%) who remained in the trial at week 260, or 5 years, 88.9% achieved at least a 75% improvement in lesion extent and severity (Eczema Area and Severity Index [EASI]-75), and 76.2% achieved an EASI-90. The proportion achieving at least a 4-point reduction in the Peak Pruritus Numerical Rating Scale (NRS) or a score of 0 was 66.5%. At 5 years, improvements “seem very stable,” with “no loss in efficacy,” Dr. Beck said.

The majority of patients who withdrew from the open-label extension trial did so because the study was terminated at their site or because of the drug’s approval and commercialization – not for a medical reason, Dr. Beck said. Over the course of the extension trial, 4% of those enrolled withdrew because of adverse events and about 2% withdrew because of lack of efficacy.

Safety of dupilumab

The extension trial lacked a control arm, so Dr. Beck and her colleagues compared safety results to those in the final data set for patients in the LIBERTY AD CHRONOS study who received dupilumab 300 mg weekly with concomitant corticosteroids. The CHRONOS study was a 1-year randomized, double-blinded placebo-controlled phase 3 trial.

The exposure-adjusted incidence rate of severe treatment-emergent adverse events (TEAE) was lower at the close of the extension trial (5 patients/100 patient years [PY]) than at the end of the CHRONOS study (5.9 patients/100 PY). The incidence of serious adverse events related to treatment was 0.6 patients/100 PY in the final open label extension study data set, compared with 0.7 patients/100 PY in the CHRONOS final data set.

Adverse event rates “are really, if anything, slightly less in the OLE study versus the CHRONOS study, which was 1 year of treatment,” Dr. Beck said. And “no new adverse events have emerged.”

During a question and answer period, Dr. Beck pointed out that existing and future “real world” registries of patients on dupilumab and other new therapies will better inform dermatologists of adverse events than clinical trials have done.
 

Ocular surface disease

In a separate presentation on the safety of biologics, Andrew Blauvelt, MD, MBA, of the Oregon Medical Research Center, Portland, said that in routine care, ocular surface disease is the most predominant side effect associated with dupilumab. “We don’t know the mechanism of action. But it’s not infectious, it’s not pink eye, and importantly, it’s not allergic conjunctivitis,” he said, noting that the spectrum of disease ranges from dry eye and eye itching to “frank conjunctivitis” and keratitis.

Most cases are mild to moderate and can often be managed with lubricating eye drops and periodic use of corticosteroid eye drops. Co-management with an ophthalmologist is often advisable, he said.

Dupilumab-associated erythema/eczema of the face was “not seen much” in clinical trials but is also being reported in the literature, largely by European researchers, Dr. Blauvelt said. “We hear a lot about red face, but I don’t think it’s much of an issue,” he said. “Most of the time, in my experience, it will [reflect] breakthrough residual AD, and I like to treat it with non-steroidal topicals.”

Occasionally, the withdrawal of steroids or allergic contact dermatitis are at play, Dr. Blauvelt said. “If you see red face in a person on dupilumab, use your clinical prowess, do a differential diagnosis, and treat accordingly.”
 

Effect on S. aureus

The vast majority of adults with moderate to severe AD have skin colonization with S. aureus, Dr. Beck said during the session on long-term control of AD. The presence of S. aureus in skin cultures correlates strongly with AD severity, type 2 immunity polarization, skin barrier disruption, and allergen sensitization, she said.

“So if we could do something to get rid of the staph and keep it away, one might imagine that would help” control the AD disease process, she said.

An ADRN study evaluated S. aureus in the skin of 71 patients who were randomized to receive dupilumab or placebo and found a “profound” effect of the biologic. “We were truly shocked by how quickly we saw a reduction in Staph aureus ... in lesional skin as early as 3 days” into treatment with dupilumab, she said of the unpublished findings. “And there is a pretty nice association with improvement in disease severity.”

Dr. Beck reported consultancy/advisory board work with Regeneron, Sanofi/Genzyme, among other disclosures. Dr. Blauvelt reported consultancy/advisory board work for Regeneron and Sanofi Genzyme and has received speakers bureau/honoraria for non-CME work for Regeneron and Sanofi, among other disclosures.

Survival from pediatric acute lymphoblastic leukemia (ALL) in a Mexican hospital improved significantly through a close cross-border collaboration with a nearby U.S. center that provided training and improved access.

A team from a hospital in San Diego combined a previously established training program from the World Health Organization with a new collaboration, which resulted in improvements in care standards and sustainability of care in a center in Tijuana, Mexico, just 23 miles away.

Implementation of the program in 2013 led to a significant 6% improvement in 5-year overall survival for children with ALL.

For patients at standard risk, 5-year overall survival increased from 73% to 100% after implementation of the program.

“This is really remarkable because this survival is the same as we have here in San Diego,” commented Paula Aristizabal, MD, MAS, a pediatric hematologist/oncologist at Rady Children’s Hospital, San Diego, at a press briefing before the annual meeting of the American Society of Clinical Oncology.

The findings show that “sustained improvements in cancer outcomes in low- and middle-income countries [LMICs] are feasible with innovative cross-border programs, particularly in borders that are shared” between a high- and low-income country, she commented. In other words, “it takes a village in both countries” to drive up standards.

Dr. Aristizabal also noted that the partnership will continue with a particularly focus on improving survival among patients with high-risk disease.

“We like to call it ‘twinning,’ because that means we are twins forever,” she said. “This is not a marriage that can be dissolved.”
 

‘Huge survival gap’

“The burden of childhood cancer has increased globally, but unfortunately, survival in low- and middle-income countries has not improved at the same level as in high-income countries,” Dr. Aristizabal commented.

This has resulted in a “huge survival gap” between high-income countries and the LMICs. ALL is now a leading cause of death among children in these countries, she commented.

“This study illustrates collaborative strategies that can be put into place today that could greatly improve outcomes for children with cancer globally,” commented Julie R. Gralow, MD, ASCO chief medical officer and executive vice president.

Speaking at the press conference, she added: “As I’ve heard Princess Dina Mired of Jordan say many times: ‘Your ZIP code should not determine if you survive cancer.’ ”

She said the differences in ALL survival between the United States and Mexico are an “example of children being so close in terms of proximity not having the same advantages.”

Also commenting, ASCO President Eric Winer, MD, from the Yale Cancer Center, New Haven, Conn., asked whether the proximity of the hospitals in San Diego and Tijuana “makes a difference, or do you think this is something that done ... at a distance?”

Dr. Aristizabal said that the proximity between the institutions “has been extremely helpful,” as they can go between hospitals in just 30 minutes.

However, “one of the things that we learned with COVID is that we can do a lot of things remotely,” she answered.

“Some of the projects that we started in Tijuana, through our collaboration with St. Jude Children’s Research Hospital, we have been able to implement in many other centers in Mexico,” she said.
 

Study details

Rady Children’s Hospital partnered with the public sector in Baja California, with the aim of improving outcomes in children’s cancer, she explained.

In 2008, the team collaborated with St. Jude Children’s Research Hospital, Memphis, to establish a training program in the Hospital General Tijuana in Tijuana that shared knowledge, technology, and organizational skills.

The team also consulted on clinical cases and set up education and research programs, all with the aim of building capacity and sustainability in Mexico.

“As the number of leukemia patients increased, we wanted to decrease depending on their international collaborators in the U.S. and ensure long-term sustainability,” Dr. Aristizabal explained.

This led in 2013 to the implementation of the WHO Framework for Action HSS training model, which has several components, including health service delivery.

Combined with the previously established model, the overall goals of the program were to improve health outcomes, systems efficiency, timely access to care, and social and financial risk protection.

Dr. Aristizabal said in an interview that this involved developing highly specific leukemia treatment guidelines, which have now gone through three iterations, as well as guidelines for supportive care.

Working with a local foundation, the team has also “focused on providing psychosocial support, nutritional support, a shelter for families that live 12-14 hours away from the pediatric cancer center, as well as food subsidies, trying to address financial toxicity and food insecurity in these families.”
 

Impact of the collaboration

To assess the impact of the WHO framework, the researchers conducted a study that involved 109 children with ALL who were treated at Hospital General Tijuana over the preimplementation phase in 2008-2012 and the postimplementation phase in 2013-2017.

The mean age of the patients was 7.04 years, and 50.4% were girls. The majority (67%) were classified as having high-risk disease.

Over the entire study period, the 5-year overall survival rate was 65%. Analysis revealed that between the pre- and postimplementation periods, 5-year overall survival increased from 59% to 65%, which Dr. Aristizabal described as “a significant improvement.”

Among high-risk patients, the improvement in 5-year survival between the pre- and postimplementation period went from 48% to 55%.

“This is an area for improvement,” Dr. Aristizabal said, “and we’re working on additional strategies to help improve survival for high-risk patients.

The study was funded by Rady Children’s Hospital, the Mexican Secretary of Health, and the Patronato Foundation. Dr. Aristizabal and coauthors reported no relevant financial relationships. Dr. Gralow reported relationships with Genentech and Roche. Dr. Winer reported relationships with Leap Therapeutics, Jounce Therapeutics, Carrick Therapeutics, and Genentech.

Survival from pediatric acute lymphoblastic leukemia (ALL) in a Mexican hospital improved significantly through a close cross-border collaboration with a nearby U.S. center that provided training and improved access.

A team from a hospital in San Diego combined a previously established training program from the World Health Organization with a new collaboration, which resulted in improvements in care standards and sustainability of care in a center in Tijuana, Mexico, just 23 miles away.

Implementation of the program in 2013 led to a significant 6% improvement in 5-year overall survival for children with ALL.

For patients at standard risk, 5-year overall survival increased from 73% to 100% after implementation of the program.

“This is really remarkable because this survival is the same as we have here in San Diego,” commented Paula Aristizabal, MD, MAS, a pediatric hematologist/oncologist at Rady Children’s Hospital, San Diego, at a press briefing before the annual meeting of the American Society of Clinical Oncology.

The findings show that “sustained improvements in cancer outcomes in low- and middle-income countries [LMICs] are feasible with innovative cross-border programs, particularly in borders that are shared” between a high- and low-income country, she commented. In other words, “it takes a village in both countries” to drive up standards.

Dr. Aristizabal also noted that the partnership will continue with a particularly focus on improving survival among patients with high-risk disease.

“We like to call it ‘twinning,’ because that means we are twins forever,” she said. “This is not a marriage that can be dissolved.”
 

‘Huge survival gap’

“The burden of childhood cancer has increased globally, but unfortunately, survival in low- and middle-income countries has not improved at the same level as in high-income countries,” Dr. Aristizabal commented.

This has resulted in a “huge survival gap” between high-income countries and the LMICs. ALL is now a leading cause of death among children in these countries, she commented.

“This study illustrates collaborative strategies that can be put into place today that could greatly improve outcomes for children with cancer globally,” commented Julie R. Gralow, MD, ASCO chief medical officer and executive vice president.

Speaking at the press conference, she added: “As I’ve heard Princess Dina Mired of Jordan say many times: ‘Your ZIP code should not determine if you survive cancer.’ ”

She said the differences in ALL survival between the United States and Mexico are an “example of children being so close in terms of proximity not having the same advantages.”

Also commenting, ASCO President Eric Winer, MD, from the Yale Cancer Center, New Haven, Conn., asked whether the proximity of the hospitals in San Diego and Tijuana “makes a difference, or do you think this is something that done ... at a distance?”

Dr. Aristizabal said that the proximity between the institutions “has been extremely helpful,” as they can go between hospitals in just 30 minutes.

However, “one of the things that we learned with COVID is that we can do a lot of things remotely,” she answered.

“Some of the projects that we started in Tijuana, through our collaboration with St. Jude Children’s Research Hospital, we have been able to implement in many other centers in Mexico,” she said.
 

Study details

Rady Children’s Hospital partnered with the public sector in Baja California, with the aim of improving outcomes in children’s cancer, she explained.

In 2008, the team collaborated with St. Jude Children’s Research Hospital, Memphis, to establish a training program in the Hospital General Tijuana in Tijuana that shared knowledge, technology, and organizational skills.

The team also consulted on clinical cases and set up education and research programs, all with the aim of building capacity and sustainability in Mexico.

CHICAGO – Sunscreen recommendations are most effective when a multitude of factors are considered, Susan C. Taylor, MD, said during a presentation on personal photoprotection at the inaugural Pigmentary Disorders Exchange Symposium.

Among the first factors physicians should consider before recommending sunscreen are a patient’s Fitzpatrick skin type, risks for burning or tanning, underlying skin disorders, and medications the patient is taking, Dr. Taylor, professor of dermatology at the University of Pennsylvania, Philadelphia, said at the meeting, provided by MedscapeLIVE! If patients are on hypertensives, for example, medications can make them more photosensitive.

MedscapeLIVE!

Consider skin type

Dr. Taylor said she was dismayed by the results of a recent study, which found that 43% of dermatologists who responded to a survey reported that they never, rarely, or only sometimes took a patient’s skin type into account when making sunscreen recommendations. The article is referenced in a 2022 expert panel consensus paper she coauthored on photoprotection “for skin of all color.” But she pointed out that considering skin type alone is inadequate.

Questions for patients in joint decision-making should include lifestyle and work choices such as whether they work inside or outside, and how much sun exposure they get in a typical day. Heat and humidity levels should also be considered as should a patient’s susceptibility to dyspigmentation. “That could be overall darkening of the skin, mottled hyperpigmentation, actinic dyspigmentation, and, of course, propensity for skin cancer,” she said.
 

Use differs by race

Dr. Taylor, who is also vice chair for diversity, equity and inclusion in the department of dermatology at the University of Pennsylvania, pointed out that sunscreen use differs considerably by race.

In study of 8,952 adults in the United States who reported that they were sun sensitive found that a subset of adults with skin of color were significantly less likely to use sunscreen when compared with non-Hispanic White adults: Non-Hispanic Black (adjusted odds ratio, 0.43); non-Hispanic Asian (aOR. 0.54); and Hispanic (aOR, 0.70) adults.

In the study, non-Hispanic Black and Hispanic adults were significantly less likely to use sunscreens with an SPF greater than 15. In addition, non-Hispanic Black, non-Hispanic Asian, and Hispanic adults were significantly more likely than non-Hispanic Whites to wear long sleeves when outside. Such differences are important to keep in mind when advising patients about sunscreens, she said.
 

Protection for lighter-colored skin

Dr. Taylor said that, for patients with lighter skin tones, “we really want to protect against ultraviolet B as well as ultraviolet A, particularly ultraviolet A2. Ultraviolet radiation is going to cause DNA damage.” Patients with Fitzpatrick skin types I, II, or III are most susceptible to the effects of UVB with sunburn inflammation, which will cause erythema and tanning, and immunosuppression.

“For those who are I, II, and III, we do want to recommend a broad-spectrum, photostable sunscreen with a critical wavelength of 370 nanometers, which is going to protect from both UVB and UVA2,” she said.

Sunscreen recommendations are meant to be paired with advice to avoid midday sun from 10 a.m. to 2 p.m., wearing protective clothing and accessories, and seeking shade, she noted.

Dr. Taylor said, for those patients with lighter skin who are more susceptible to photodamage and premature aging, physicians should recommend sunscreens that contain DNA repair enzymes such as photolyases and sunscreens that contain antioxidants that can prevent or reverse DNA damage. “The exogenous form of these lyases have been manufactured and added to sunscreens,” Dr. Taylor said. “They’re readily available in the United States. That is something to consider for patients with significant photodamage.”

Retinoids can also help alleviate or reverse photodamage, she added.
 

Protection for darker-colored skin

“Many people of color do not believe they need sunscreen,” Dr. Taylor said. But studies show that, although there may be more intrinsic protection, sunscreen is still needed.

Over 30 years ago, Halder and colleagues reported that melanin in skin of color can filter two to five times more UV radiation, and in a paper on the photoprotective role of melanin, Kaidbey and colleagues found that skin types V and VI had an intrinsic SPF of 13 when compared with those who have lighter complexions, which had an SPF of 3.

Sunburns seem to occur less frequently in people with skin of color, but that may be because erythema is less apparent in people with darker skin tones or because of differences in personal definitions of sunburn, Dr. Taylor said.

“Skin of color can and does sustain sunburns and sunscreen will help prevent that,” she said, adding that a recommendation of an SPF 30 is likely sufficient for these patients. Dr. Taylor noted that sunscreens for patients with darker skin often cost substantially more than those for lighter skin, and that should be considered in recommendations.

Tinted sunscreens

Dr. Taylor said that, while broad-spectrum photostable sunscreens protect against UVB and UVA 2, they don’t protect from visible light and UVA1. Two methods to add that protection are using inorganic tinted sunscreens that contain iron oxide or pigmentary titanium dioxide. Dr. Taylor was a coauthor of a practical guide to tinted sunscreens published in 2022.

“For iron oxide, we want a concentration of 3% or greater,” she said, adding that the percentage often is not known because if it is contained in a sunscreen, it is listed as an inactive ingredient.

Another method to address visible light and UVA1 is the use of antioxidant-containing sunscreens with vitamin E, vitamin C, or licochalcone A, Dr. Taylor said.

During the question-and-answer period following her presentation, Amit Pandya, MD, adjunct professor of dermatology at University of Texas Southwestern Medical Center, Dallas, asked why “every makeup, every sunscreen, just says iron oxide,” since it is known that visible light will cause pigmentation, especially in those with darker skin tones.

He urged pushing for a law that would require listing the percentage of iron oxide on products to assure it is sufficient, according to what the literature recommends.

Conference Chair Pearl Grimes, MD, director of the Vitiligo and Pigmentation Institute of Southern California, Los Angeles, said that she recommends tinted sunscreens almost exclusively for her patients, but those with darker skin colors struggle to match color.

Dr. Taylor referred to an analysis published in 2022 of 58 over-the counter sunscreens, which found that only 38% of tinted sunscreens was available in more than one shade, “which is a problem for many of our patients.” She said that providing samples with different hues and tactile sensations may help patients find the right product.

Dr. Taylor disclosed being on the advisory boards for AbbVie, Avita Medical, Beiersdorf, Biorez, Eli Lily, EPI Health, Evolus, Galderma, Hugel America, Johnson and Johnson, L’Oreal USA, MedScape, Pfizer, Scientis US, UCB, Vichy Laboratories. She is a consultant for Arcutis Biothermapeutics, Beiersdorf, Bristol-Myers Squibb, Cara Therapeutics, Dior, and Sanofi. She has done contracted research for Allergan Aesthetics, Concert Pharmaceuticals, Croma-Pharma, Eli Lilly, and Pfizer, and has an ownership interest in Armis Scientific, GloGetter, and Piction Health.

Dr. Taylor referred to an analysis published in 2022 of 58 over-the counter sunscreens, which found that only 38% of tinted sunscreens was available in more than one shade, “which is a problem for many of our patients.” She said that providing samples with different hues and tactile sensations may help patients find the right product.

Dr. Taylor disclosed being on the advisory boards for AbbVie, Avita Medical, Beiersdorf, Biorez, Eli Lily, EPI Health, Evolus, Galderma, Hugel America, Johnson and Johnson, L’Oreal USA, MedScape, Pfizer, Scientis US, UCB, Vichy Laboratories. She is a consultant for Arcutis Biothermapeutics, Beiersdorf, Bristol-Myers Squibb, Cara Therapeutics, Dior, and Sanofi. She has done contracted research for Allergan Aesthetics, Concert Pharmaceuticals, Croma-Pharma, Eli Lilly, and Pfizer, and has an ownership interest in Armis Scientific, GloGetter, and Piction Health.

MANNHEIM, Germany – Lomitapide, which reduces lipoprotein production in the liver, could help manage pediatric homozygous familial hypercholesterolemia (HoFH), suggest results of a trial that showed large reductions in circulating lipids.

The research was presented May 23 at the 91st European Atherosclerosis Society Congress.

Lomitapide inhibits microsomal triglyceride transfer protein, which plays a key role in apolipoprotein B-containing lipoprotein assembly and secretion in the liver and intestines. Crucially, the drug acts independently of the LDL cholesterol receptor.

It was approved in December 2012 by the U.S. Food and Drug Administration for use in adults with HoFH, sold under the name Juxtapid, and by the European Medicines Agency, where the brand name is Lojuxta.

The current trial involved more than 40 children and teenagers with HoFH aged 5-17 years; they were treated with the drug for 24 weeks, resulting in reductions of low density lipoprotein cholesterol of almost 54%, with nearly 42% reaching target levels.

The drug was also associated with marked reductions in other key lipids of at least 50%. However, 67% of patients also experienced gastrointestinal adverse events, and around 25% saw their levels of liver enzymes increase.
 

Early diagnosis ‘imperative’

The findings show that the “early diagnosis and treatment of HoFH is imperative,” said study presenter Luis Masana, MD, PhD, director of the Vascular Medicine and Metabolism Unit at Sant Joan de Reus University Hospital, Tarragona, Spain.

“I think that, with these results, we are bringing a new hope for this group of patients,” he continued. “I also think we will increase the quality of life, not just of the patients but also all the families involved in [managing] this problem.”

Session co-chair Andreas Zirlik, MD, PhD, head of the department of cardiology and chairman of the University Heart Center Graz, LKH-University Hospital, and Medical University of Graz (Austria), was more circumspect in his appraisal of the results.

He told this news organization that it is “always very difficult to establish therapy in pediatrics,” and believes that the drug “will give us an additional option” in managing HoFH.

However, Dr. Zirlik warned that he is a “little bit concerned” about lomitapide’s adverse event profile, and “would need to see a little bit deeper into the safety data.”

Highlighting the elevations in liver enzymes of around 25%, he asked: “What does it mean?” And how will it “play out in the long run?”

Beyond lomitapide, Dr. Zirlik pointed out that there are other drugs that have shown potential in managing HoFH and could potentially be used in the pediatric population, such as angiopoietin-like 3 protein (ANGPTL3) inhibitors and small interfering RNA (siRNA) compounds that target upstream production. “So, let’s see how they pan out,” he said.
 

Life-limiting condition

HoFH is an “ultra-rare, life-limiting condition,” with an estimated prevalence of approximately 3 per 1 million people, and a life expectancy in untreated patients of just 18 years, Dr. Masana said during his presentation.

Case series of lomitapide use in pediatric HoFH patients have shown encouraging results that are consistent with those seen in adults, he noted, with many able to achieve their LDL cholesterol target and stop or reduce apheresis.

To investigate further, a phase 3, single arm, open-label study was conducted. Following screening, 46 children and teenagers with HoFH underwent a 6- to 12-week run-in period, during which they were put on a low-fat diet with nutritional supplements.

“As you can imagine,” Dr. Masana said, “we are reducing the capacity for fat absorption with lomitapide, so the supplements and low-fat diet are necessary.”

Of these, 43 participants then entered a 24-week treatment period in which they were started on one of three doses, before undergoing dose escalation to the maximally tolerated dose. This was followed by an 80-week open-label safety phase, in which they continued on the maximally tolerated dose, then a follow-up period.

For the current presentation, Dr. Masana focused on the efficacy phase, showing that the mean age of participants was 10.7 years and that 55.8% were female. The HoFH diagnosis was confirmed genetically in 88.4% of cases.

Results showed that lomitapide was associated with a significant reduction in LDL cholesterol levels, from 435.8 mg/dL at baseline to 176.5 mg/dL at Week 24, which corresponded to a 53.5% overall reduction (P < .0001).

This meant that 41.9% of patients achieved their EAS LDL cholesterol target of less than 135 mg/dL at some point during the 24-week treatment period.

Stratifying by age, the reduction between baseline and week 24 was 538.5 mg/dL to 207.2 mg/dL, or 56.5%, in the 20 children aged 5-10 years, and 346.5 mg/dL to 149.9 mg/L, or 50.9%, in the 23 patients aged 11-17 years.

Dr. Masana explained that the results were “a little bit better in the younger group because they were receiving less treatment at this stage of the disease” than the older group.

He showed that lomitapide was associated with significant reductions in other lipid markers, including a 53.9% reduction in non–HDL cholesterol (P < .0001), a 50.1% drop in total cholesterol (P < .0001), and a 50.2% fall in very-low-density lipoprotein cholesterol (P < .0001).

Results showed 93% of patients experienced treatment-related adverse events, with 11.6% having serious events and 4.7% having events that led to study discontinuation. There was one (2.3%) major adverse cardiac event but no deaths.

He said that, despite these figures, the adverse events were “mostly mild or moderate.”

The majority (67%) of patients nevertheless had gastrointestinal adverse events, which were, “in general, associated with a lack of adherence to the low-fat diet.”

Aspartate aminotransferase levels were elevated in 23% of patients, while 28% had elevations in alanine aminotransferase, which were described by Dr. Masana as “moderate.”

The study was sponsored by Amryt Pharma. Dr. Masana declares relationships with Amarin, Amryt, Daiichi-Sankyo, Novartis, Sanofi, Servier, Servier, and Viatrix.

SAN FRANCISCO – Children randomly assigned to foster care after being institutionalized in infancy have significantly better cognitive and physical outcomes and less severe symptoms of psychopathology than their peers who remain in institutional care, results of a new study suggest.

The study shows that sustained recovery is possible after severe, early-life adversity, study author Kathryn L. Humphreys, PhD, assistant professor, department of psychology and human development, Vanderbilt University, Nashville, Tenn., said in an interview.

Vanderbilt University

“Given the strong evidence from the present study, I hope physicians will play a role in promoting family placements as an alternative to institutional care for children who have been orphaned,” she said.

The findings were presented at the annual meeting of the American Psychiatric Association and were published online in the American Journal of Psychiatry.

Millions of children around the world experience psychosocial deprivation while living in institutions, and many more are neglected in their families of origin. In addition, about 6.7 million children lost a parent or caregiver during the COVID-19 pandemic.

In particular, Romania has a history of institutionalizing children. Through decades of repressive policies from the Romanian dictator Nicolae Ceausescu, child abandonment became a national disaster. Families couldn’t afford to keep their children and were encouraged to turn them over to the state.

The current study was part of the Bucharest Early Intervention Project, initiated in 2001 to examine the impact of high-quality, family-based care on development. It included 136 Romanian children (mean age, about 22 months) who were abandoned at or shortly after birth and were placed in an institution.

Researchers randomly assigned each toddler to 1 of 56 foster families or to continue living in an institution (care as usual). The researchers had to create a foster care network, because such care was extremely limited at the start of the study.
 

Providing stimulating care

Foster parents in the study received regular support from social workers and U.S.-based psychologists. They were encouraged to “make a commitment to treat the child as if it was their own, providing sensitive, stimulating, and nurturing care, not just in the short term but for their whole life,” said Dr. Humphreys.

Foster care programs in the United States have been criticized for focusing on short-term care, she said. “It’s really just a bed to sleep on, clothes to wear, and food to eat rather than the psychological component we think is really important for child development.”

For the study, the researchers assessed the children across multiple developmental domains at baseline and at ages 30, 42, and 54 months. They conducted additional assessments when the kids were aged 8, 12, and 16-18 years.

The primary outcomes were cognitive functioning (IQ), physical growth (height, weight, head circumference), brain electrical activity (relative electroencephalography power in the alpha frequency band), and symptoms of five types of psychopathology (disinhibited social engagement disorder, reactive attachment disorder, ADHD symptoms, externalizing symptoms, and internalizing symptoms).

From over 7,000 observations analyzed across follow-ups, the investigators found that the intervention had an overall significant effect on cognitive, physical, and neural outcomes when considered collectively across waves (beta, 0.26; 95% confidence interval, 0.07-0.46; P = .012). Compared to children who received care as usual, those in foster homes had significantly higher average IQ scores (P < .001) and physical size (P = .008).

The intervention had an overall beneficial effect in regard to psychopathology. The greatest impact involved a reduction in symptoms of reactive attachment disorder (P < .001).

“There are a few forms of psychopathology that seem to almost entirely occur after severe neglect, including reactive attachment disorder; we think of these as disorders of social relatedness that derive from aberrant or insufficient early caregiving experiences,” said Dr. Humphreys. “Being placed in a family reduced the symptoms of reactive attachment disorder to pretty much nonexistent.”

To a lesser extent, the intervention reduced symptoms of disinhibited social engagement disorder. The foster care group also had significantly fewer internalizing symptoms than did children in the care-as-usual group.

But there was no significant overall effect of the intervention on symptoms of ADHD or externalizing problems.
 

Positive effects persisted

For the most part, the positive effects of the intervention on children’s functioning persisted during nearly 2 decades of follow-up. The impact of the intervention “can be described as rapidly apparent by age 30 months and sustained through late adolescence,” wrote the authors.

Regarding the impact of age at the time of placement, the study found that, compared with children placed into foster care later, those who entered foster care earlier (younger than 33 months) had significantly higher IQ scores and relative alpha power, but there was no difference in physical growth.

For some outcomes, the benefits of earlier placement were apparent in early childhood but faded by adolescence. But Dr. Humphreys noted all placements were early by most definitions.

The researchers also assessed stability of foster care placements. Children were considered “stable” if they remained with their original foster family; they were considered “disrupted” if they no longer resided with the family.

Here, the study found some “striking results,” said Dr. Humphreys. The effect of placement stability was largest in adolescence, when, overall, those who had remained with their original foster family had better cognitive and physical outcomes and less severe symptoms of psychopathology compared to those who experienced placement disruptions.

As for sex differences, “it’s a mixed bag,” said Dr. Humphreys, although overall, “we didn’t see strong evidence of sex differences” in terms of outcomes.

The investigators were unable to examine trajectories of children’s functioning, which would have provided important information on aspects such as rate of growth and the shape of growth curves. Specific features of the institutional or foster care environment in Bucharest during the study may limit the generalizability of the findings to other settings.
 

Absolutely unique project

The study examined an “absolutely unique project” and had “very exciting” results that should have “important clinical implications,” commented the American Journal of Psychiatry editor-in-chief Ned Kalin, MD, Hedberg Professor and chair, department of psychiatry, University of Wisconsin–Madison.

The findings are “pretty dramatic,” added Dr. Kalin. “This is probably the study to be thinking about when considering the future of treatment and interventions in children who have suffered from this type of neglect, which is unfortunately extremely common worldwide, including in the U.S.”

In particular, the findings regarding improved psychopathology “bode well for the future,” said Dr. Kalin. “We know these types of problems are risk factors for the later development of depression and anxiety disorders. It will be really interesting to find out, but my guess is these kids will be protected as they mature further.”

The study was supported by the NIH, the John D. and Catherine T. MacArthur Foundation, the Palix Foundation, and the Jacobs Foundation. Dr. Humphreys has received research funding from the Brain and Behavior Research Foundation, the Caplan Foundation, the Jacobs Foundation, the National Science Foundation, the NIH, the Vanderbilt Institute for Clinical and Translational Research, the Vanderbilt Kennedy Center, and Vanderbilt University; she has received honoraria from the Journal of Clinical Child and Adolescent Psychology Future Directions Forum, Learning Grove, the University of Iowa, the University of Texas at Austin, and ZERO TO THREE.

The study was supported by the NIH, the John D. and Catherine T. MacArthur Foundation, the Palix Foundation, and the Jacobs Foundation.

SAN FRANCISCO – Children randomly assigned to foster care after being institutionalized in infancy have significantly better cognitive and physical outcomes and less severe symptoms of psychopathology than their peers who remain in institutional care, results of a new study suggest.

The study shows that sustained recovery is possible after severe, early-life adversity, study author Kathryn L. Humphreys, PhD, assistant professor, department of psychology and human development, Vanderbilt University, Nashville, Tenn., said in an interview.

“Given the strong evidence from the present study, I hope physicians will play a role in promoting family placements as an alternative to institutional care for children who have been orphaned,” she said.

The findings were presented at the annual meeting of the American Psychiatric Association and were published online in the American Journal of Psychiatry.

Millions of children around the world experience psychosocial deprivation while living in institutions, and many more are neglected in their families of origin. In addition, about 6.7 million children lost a parent or caregiver during the COVID-19 pandemic.

In particular, Romania has a history of institutionalizing children. Through decades of repressive policies from the Romanian dictator Nicolae Ceausescu, child abandonment became a national disaster. Families couldn’t afford to keep their children and were encouraged to turn them over to the state.

The current study was part of the Bucharest Early Intervention Project, initiated in 2001 to examine the impact of high-quality, family-based care on development. It included 136 Romanian children (mean age, about 22 months) who were abandoned at or shortly after birth and were placed in an institution.

Researchers randomly assigned each toddler to 1 of 56 foster families or to continue living in an institution (care as usual). The researchers had to create a foster care network, because such care was extremely limited at the start of the study.
 

Providing stimulating care

Foster parents in the study received regular support from social workers and U.S.-based psychologists. They were encouraged to “make a commitment to treat the child as if it was their own, providing sensitive, stimulating, and nurturing care, not just in the short term but for their whole life,” said Dr. Humphreys.

Foster care programs in the United States have been criticized for focusing on short-term care, she said. “It’s really just a bed to sleep on, clothes to wear, and food to eat rather than the psychological component we think is really important for child development.”

For the study, the researchers assessed the children across multiple developmental domains at baseline and at ages 30, 42, and 54 months. They conducted additional assessments when the kids were aged 8, 12, and 16-18 years.

The primary outcomes were cognitive functioning (IQ), physical growth (height, weight, head circumference), brain electrical activity (relative electroencephalography power in the alpha frequency band), and symptoms of five types of psychopathology (disinhibited social engagement disorder, reactive attachment disorder, ADHD symptoms, externalizing symptoms, and internalizing symptoms).

From over 7,000 observations analyzed across follow-ups, the investigators found that the intervention had an overall significant effect on cognitive, physical, and neural outcomes when considered collectively across waves (beta, 0.26; 95% confidence interval, 0.07-0.46; P = .012). Compared to children who received care as usual, those in foster homes had significantly higher average IQ scores (P < .001) and physical size (P = .008).

The intervention had an overall beneficial effect in regard to psychopathology. The greatest impact involved a reduction in symptoms of reactive attachment disorder (P < .001).

“There are a few forms of psychopathology that seem to almost entirely occur after severe neglect, including reactive attachment disorder; we think of these as disorders of social relatedness that derive from aberrant or insufficient early caregiving experiences,” said Dr. Humphreys. “Being placed in a family reduced the symptoms of reactive attachment disorder to pretty much nonexistent.”

To a lesser extent, the intervention reduced symptoms of disinhibited social engagement disorder. The foster care group also had significantly fewer internalizing symptoms than did children in the care-as-usual group.

But there was no significant overall effect of the intervention on symptoms of ADHD or externalizing problems.
 

Positive effects persisted

For the most part, the positive effects of the intervention on children’s functioning persisted during nearly 2 decades of follow-up. The impact of the intervention “can be described as rapidly apparent by age 30 months and sustained through late adolescence,” wrote the authors.

Regarding the impact of age at the time of placement, the study found that, compared with children placed into foster care later, those who entered foster care earlier (younger than 33 months) had significantly higher IQ scores and relative alpha power, but there was no difference in physical growth.

For some outcomes, the benefits of earlier placement were apparent in early childhood but faded by adolescence. But Dr. Humphreys noted all placements were early by most definitions.

The researchers also assessed stability of foster care placements. Children were considered “stable” if they remained with their original foster family; they were considered “disrupted” if they no longer resided with the family.

Here, the study found some “striking results,” said Dr. Humphreys. The effect of placement stability was largest in adolescence, when, overall, those who had remained with their original foster family had better cognitive and physical outcomes and less severe symptoms of psychopathology compared to those who experienced placement disruptions.

As for sex differences, “it’s a mixed bag,” said Dr. Humphreys, although overall, “we didn’t see strong evidence of sex differences” in terms of outcomes.

The investigators were unable to examine trajectories of children’s functioning, which would have provided important information on aspects such as rate of growth and the shape of growth curves. Specific features of the institutional or foster care environment in Bucharest during the study may limit the generalizability of the findings to other settings.
 

Absolutely unique project

The study examined an “absolutely unique project” and had “very exciting” results that should have “important clinical implications,” commented the American Journal of Psychiatry editor-in-chief Ned Kalin, MD, Hedberg Professor and chair, department of psychiatry, University of Wisconsin–Madison.

The findings are “pretty dramatic,” added Dr. Kalin. “This is probably the study to be thinking about when considering the future of treatment and interventions in children who have suffered from this type of neglect, which is unfortunately extremely common worldwide, including in the U.S.”

In particular, the findings regarding improved psychopathology “bode well for the future,” said Dr. Kalin. “We know these types of problems are risk factors for the later development of depression and anxiety disorders. It will be really interesting to find out, but my guess is these kids will be protected as they mature further.”

The study was supported by the NIH, the John D. and Catherine T. MacArthur Foundation, the Palix Foundation, and the Jacobs Foundation. Dr. Humphreys has received research funding from the Brain and Behavior Research Foundation, the Caplan Foundation, the Jacobs Foundation, the National Science Foundation, the NIH, the Vanderbilt Institute for Clinical and Translational Research, the Vanderbilt Kennedy Center, and Vanderbilt University; she has received honoraria from the Journal of Clinical Child and Adolescent Psychology Future Directions Forum, Learning Grove, the University of Iowa, the University of Texas at Austin, and ZERO TO THREE.

SAN FRANCISCO – During the pandemic, there was a significant increase in vitamin D deficiency in pediatric patients with major depressive disorder, according to new findings that suggest spending more time indoors may have fueled this uptick.

“We suspect that this may be due to the COVID lockdowns and kids schooling from home and having less time outside,” study investigator Oluwatomiwa Babade, MD, MPH, with Virginia Tech Carilion School of Medicine, Roanoke, Va., said in an interview.

The study was presented at the annual meeting of the American Psychiatric Association.
 

Anecdotal observation confirmed

During the pandemic, investigators noticed an uptick in the number of children and adolescents attending their clinic for psychiatric hospitalization who had low vitamin D levels.

To investigate, they analyzed the records of all patients aged 6-17 years with psychiatric diagnoses and vitamin D level assessment who were admitted into the inpatient psychiatry unit from March 18, 2020, to June 30, 2021.

Among 599 unique patients, 275 (83% female) had a diagnosis of MDD and 226 of these patients were vitamin D deficient (< 30 ng/mL) – a prevalence rate of roughly 82%. Among 246 patients with psychiatric disorders other than MDD, the prevalence of vitamin D deficiency was 76%.

“This was very surprising and much higher than prior to the pandemic. Prior to COVID, the prevalence of vitamin D deficiency was around 14% in similar patients,” Dr. Babade said.

“Now that we are post-lockdown, it would be good to repeat the study. I think the prevalence should drop. That’s my guess,” he added.
 

Important research, no surprises

In a comment, Cemre Robinson, MD, director of the Mount Sinai Pediatric Bone Health and Calcium Metabolism Clinic, New York, said that although the study’s findings aren’t surprising, “it’s important to present such data in adolescents with major depression.”

“These findings reiterate the importance of screening for vitamin D deficiency in children and adolescents, with or without depression, particularly during winter, which is associated with less sun exposure,” Dr. Robinson, assistant professor of pediatrics, endocrinology, and diabetes at Icahn School of Medicine at Mount Sinai, said.

She noted that vitamin D deficiency is prevalent in the general population, and it can be easily corrected with supplementation.

“Vitamin D is important for bone growth, mineralization, and accretion as well as calcium absorption. Adolescence, in particular, is a period of rapid physical, cognitive, and psychosocial growth,” Dr. Robinson said.

“The requirement of all minerals and vitamins changes in this phase of life. Therefore, it is important to have sufficient vitamin D levels during adolescence for several health benefits,” she noted.

Dr. Robinson said that “more research is needed to validate the present findings in adolescents with major depression, and larger studies, including randomized control trials, are required to establish a causal association between MDD and vitamin D deficiency.”

The study had no specific funding. Dr. Babade and Dr. Robinson report no relevant financial relationships.

Deaths of children who are killed by their parents often make the news. Cases of maternal infanticide may be particularly shocking, since women are expected to be selfless nurturers. Yet when a child is murdered, the most common perpetrator is their parent, and mothers and fathers kill at similar rates.¹

As psychiatrists, we may see these cases in the news and worry about the risks of our own patients killing their children. In approximately 500 cases annually, an American parent is arrested for the homicide of their child.² This is not even the entire story, since a large percentage of such cases end in suicide—and no arrest. This article reviews the reasons parents kill their children, and considers common characteristics of these parents, dispelling some myths, before discussing the importance of prevention efforts.

Types of child murder by parents

Child murder by parents is termed filicide. Infanticide has various meanings but often refers to the murder of a child younger than age 1. Approximately 2 dozen nations (but not the United States) have Infanticide Acts that decrease the penalty for mothers who kill their young child.³ Neonaticide refers to murder of the infant at birth or in the first day of life.⁴

Epidemiology and common characteristics

Approximately 15%—or 1 in 7 murders with an arrest—is a filicide.² The younger the child, the greater the risk, but older children are killed as well.² Internationally, fathers and mothers are found to kill at similar rates. For other types of homicide, offenders are overwhelmingly male. This makes child murder by parents the singular type of murder in which women and men perpetrate in equal numbers. Fathers are more likely than mothers to also commit suicide after they kill their children.⁵ The “Cinderella effect” refers to the elevated risk of a stepchild being killed compared to the risk for a biological child.⁶

In the general international population, mothers who commit filicide tend to have multiple stressors and limited resources. They may be socially isolated and may be victims themselves as well as potentially experiencing substance abuse.¹ Some mothers view the child they killed as abnormal.

Less research has been conducted about fathers who kill. Fathers are more likely to also commit partner homicide.^5,7 They are more likely to complete filicide-suicide and use firearms or other violent means.^5,7-9 Fathers may have a history of violence, substance abuse, and/or mental illness.⁷

Neonaticide

Mothers are the most common perpetrator of neonaticide.⁴ It is unusual for a father to be involved in a neonaticide, or for the father and mother to perpetrate the act together. Rates of neonaticide are considered underestimates because of the number of hidden pregnancies, hidden corpses, and the difficulty that forensic pathologists may have in determining whether a baby was born alive or dead.

Continue to: Perpetrators of neonaticide...

Perpetrators of neonaticide tend to be single, relatively young women acting alone. They often live with their parents and are fearful of the repercussions of being pregnant. Pregnancies are often hidden, with no prenatal care. This includes both denial and concealment of pregnancy.⁴ Perpetrators of neonaticide commonly lack a premorbid serious mental illness, though after the homicide they may develop anxiety, depression, posttraumatic stress disorder (PTSD), or adjustment disorder.⁴ (Individuals who unwittingly find a murdered baby’s corpse may also be at risk of PTSD.)

Hidden pregnancies may be due to concealment or denial of pregnancy.^10,11 Concealment of pregnancy involves a woman knowing she is pregnant, but purposely hiding from others. Concealment may occur after a period of denial of pregnancy. Denial of pregnancy has several subtypes: pervasive denial, affective denial, and psychotic denial. In cases of pervasive denial, the existence of the pregnancy and the pregnancy’s emotional significance is outside the woman’s awareness. Alternatively, in affective denial, she is intellectually aware that she is pregnant but makes little emotional or physical preparation. In the rarest form, psychotic denial, a woman with a psychotic disorder such as schizophrenia may intermittently deny her pregnancy. This may be correlated with a history of custody loss.^10,11 Unlike denial of other medical conditions, in cases of denial of pregnancy, there will exist a very specific point in time (delivery) when the reality of the baby confronts the woman. Risks in cases of hidden pregnancies include those from lack of prenatal care and an assisted delivery as well as neonaticide. An FBI study¹² of law enforcement files found most neonaticide offenders were single young women with no criminal or psychological history. A caveat is that in the rare cases in which a woman with psychotic illness commits neonaticide, she may have different characteristics from those generally reported.¹³

Motives

Fathers and mothers have a similar set of motives for killing their child (Table 1^13-15). Motives are critical to understand not only within forensics, but also for prevention. In performing assessments after a filicide, forensic psychiatrists must be mindful of gender bias.^7,16 Resnick¹⁵ initially described 5 motives based on his 1969 review of the world literature. Our work^5,17 has subsequently further explored these motives.

In child homicides from “fatal maltreatment,” the child has often been a chronic victim of abuse or neglect. National American data indicate that approximately 2 per 100,000 children are killed from child maltreatment annually. Of note in conceptualizing prevention, out of the same population of 100,000, there will be 471 referrals to Child Protective Services and 91 substantiated cases.¹⁸ However, only a minority of children who die from maltreatment had previous Child Protective Services involvement. While a child may be killed by fatal maltreatment at any age, one-half are younger than age 1, and three-quarters are younger than age 3.¹⁸ In rare cases, a parent who engages in medical child abuse (including factitious disorder imposed upon another) kills the child. Depending on the location and whether or not the death appeared to be intended, parents who kill because of fatal maltreatment might face charges of various levels of murder or manslaughter.

“Unwanted child” homicides occur when the parent has determined that they do not want to have the child, especially in comparison to another need or want. Unwanted child motive is the most common in neonaticide cases, occurring after a hidden pregnancy.⁴

Continue to: In "partner revenge" cases...

In “partner revenge” cases, parenting disputes, a custody battle, infidelity, or a difficult relationship breakup is often present. The parent wants to make the other parent suffer, and does so by killing their child. A parent may make statements such as “If I can’t have [the child], no one can,” and the child is used as a pawn.

In the final 2 motives—“altruistic” and “acutely psychotic”—mental illness is common. These are the populations we tend to find in samples of filicide-suicide cases where the parent has killed themselves and their child, and those found not guilty by reason of insanity.^5,17 Altruistic filicide has been described as “murder out of love.” How can a parent kill their child out of love? Our research has shown several ways. First, the parent may be severely depressed and suicidal. They may be planning their own suicide, and as a parent who loves their child, they plan to take their child with them in death and not leave them alone in the “cruel world” that they themselves are departing. Or the parent may believe they are killing the child out of love to prevent or relieve the child’s suffering. The psychotic parent may believe that a terrible fate will befall their child, and they are killing them “gently.” For example, the parent may believe the child will be tortured or sex trafficked. Some parents may believe that their child has a devastating disease and think they would be better off dead. (Similar thinking of misguided altruism is seen in some cases of intimate partner homicide among older adults.¹⁹)

Alternatively, in rare cases of acutely psychotic filicide, parents with psychosis kill their child with no comprehensible motive. For example, they may be in a postictal state or may hear a command hallucination from God in the context of their psychosis.¹⁵

Myths vs realities of filicide

Common myths vs the realities of filicide are noted in Table 2. There are issues with believing these myths. For example, if we believe that most parents who kill their child have mental illness, this conflates mental illness and child homicide in our minds as well as the mind of the public. This can lead to further stigmatization of mental illness, and a lack of help-seeking behaviors because parents experiencing psychiatric symptoms may be afraid that if they report their symptoms, their child will be removed by Child Protective Services. However, treated mental illness decreases the risks of child abuse, similar to how treating mental illness decreases risks of other types of violence.^20,21

Focusing on prevention

On a local level, we need to understand these tragedies to better understand prevention. To this end, across the United States, counties have Child Fatality Review teams.²² These teams are a partnership across sectors and disciplines, including professionals from health services, law enforcement, and social services—among others—working together to understand cases and consider preventive strategies and additional services needed within our communities.

Continue to: When conceptualizing prevention...

When conceptualizing prevention of child murder by parents, we can think of primary, secondary, and tertiary prevention. This means we want to encourage healthy families and healthy relationships within the family, as well as screening for risk and targeting interventions for families that have experienced difficulties, as well as for parents who have mental illness or substance use disorders.

Understanding the motive behind an individual committing filicide is also critical so that we do not conflate filicide and mental illness. Conflating these concepts leads to increased stigmatization and less help-seeking behavior.

Table 3^{3,4,7,18,22,23} describes the importance of understanding the motives for child murder by a parent in order to conceptualize appropriate prevention. Prevention efforts for 1 type of child murder will not necessarily help prevent murders that occur due to the other motives. Regarding prevention for fatal maltreatment cases, poor parenting skills, including inappropriate expressions of discipline, anger, and frustration, are common. In some cases, substance abuse is involved or the parent was acutely mentally unwell. Reporting to Child Protective Services can be helpful, but as previously noted, it is difficult to ascertain which cases will lead to a homicide. Recommendations from Child Fatality Review teams also are valuable.

Though many parents have frustrations with their children or thoughts of child harm, the act of filicide is rare, and individual cases may be difficult to predict. Regarding prediction, some mothers who committed filicide saw their psychiatrist within days to weeks before the murders.¹⁷ A small New Zealand study found that psychotic mothers reported no plans for killing their children in advance, whereas depressed mothers had contemplated the killing for days to weeks.²⁴

Several studies have asked mothers about thoughts of harming their child. Among mothers with colicky infants, 70% reported “explicit aggressive thoughts and fantasies” while 26% had “infanticidal thoughts” during a colic episode.²⁵ Another study²⁶ found that among depressed mothers of infants and toddlers, 41% revealed thoughts of harming their child. Women with postpartum depression preferred not to share infanticidal thoughts with their doctor but were more likely to disclose that they were having suicidal thoughts in order to get needed help.²⁷ Psychiatrists need to feel comfortable asking mothers about their coping skills, their suicidal thoughts, and their filicidal thoughts.^14,23,28 Screening and treatment of mental illness is critical. Postpartum psychosis is well-known to pose an elevated risk of filicide and suicide.²³ Obsessive-compulsive disorder may cause a parent to ruminate over ego-dystonic child harm but should be treated and the risk conceptualized very differently than in postpartum psychosis.^23,29 Screening for postpartum depression and appropriate treatment of depression during pregnancy and the postpartum period decrease risk.³⁰

Continue to: Regarding prevention of neonaticide...

Regarding prevention of neonaticide, Safe Haven laws, baby boxes, anonymous birth options, and increased contraceptive information and availability can help decrease the risk of this well-defined type of homicide.⁴ Safe Haven laws originated from Child Fatality Review teams.²⁴ Though each state has its own variation, in general, parents can drop off an unharmed unwanted infant into Safe Havens in their state, which may include hospitals, police stations, or fire stations. In general, the mother remains anonymous and has immunity from prosecution for (safe) abandonment. There are drawbacks, such as lack of information regarding adoption and paternal rights. Safe Haven laws do not prevent all deaths and all unsafe abandonments. Baby boxes and baby hatches are used in various nations, including in Europe, and in some places have been used for centuries. In anonymous birth options, such as in France, a mother is not identified but is able to give birth at a hospital. This can decrease the risk from unattended delivery, but many women with denial of pregnancy report that they did not realize when they were about to give birth.⁴

Bottom Line

Knowledge about the intersection of mental illness and filicide can help in prevention. Parents who experience mental health concerns should be encouraged to obtain needed treatment, which aids prevention. However, many other factors elevate the risk of child murder by parents.

Of note in conceptualizing prevention, out of the same population of 100,000, there will be 471 referrals to Child Protective Services and 91 substantiated cases.¹⁸ However, only a minority of children who die from maltreatment had previous Child Protective Services involvement. While a child may be killed by fatal maltreatment at any age, one-half are younger than age 1, and three-quarters are younger than age 3.¹⁸ In rare cases, a parent who engages in medical child abuse (including factitious disorder imposed upon another) kills the child. Depending on the location and whether or not the death appeared to be intended, parents who kill because of fatal maltreatment might face charges of various levels of murder or manslaughter.

“Unwanted child” homicides occur when the parent has determined that they do not want to have the child, especially in comparison to another need or want. Unwanted child motive is the most common in neonaticide cases, occurring after a hidden pregnancy.⁴

In “partner revenge” cases, parenting disputes, a custody battle, infidelity, or a difficult relationship breakup is often present. The parent wants to make the other parent suffer, and does so by killing their child. A parent may make statements such as “If I can’t have [the child], no one can,” and the child is used as a pawn.

In the final 2 motives—“altruistic” and “acutely psychotic”—mental illness is common. These are the populations we tend to find in samples of filicide-suicide cases where the parent has killed themselves and their child, and those found not guilty by reason of insanity.^5,17 Altruistic filicide has been described as “murder out of love.” How can a parent kill their child out of love? Our research has shown several ways. First, the parent may be severely depressed and suicidal. They may be planning their own suicide, and as a parent who loves their child, they plan to take their child with them in death and not leave them alone in the “cruel world” that they themselves are departing. Or the parent may believe they are killing the child out of love to prevent or relieve the child’s suffering. The psychotic parent may believe that a terrible fate will befall their child, and they are killing them “gently.” For example, the parent may believe the child will be tortured or sex trafficked. Some parents may believe that their child has a devastating disease and think they would be better off dead. (Similar thinking of misguided altruism is seen in some cases of intimate partner homicide among older adults.¹⁹)

Alternatively, in rare cases of acutely psychotic filicide, parents with psychosis kill their child with no comprehensible motive. For example, they may be in a postictal state or may hear a command hallucination from God in the context of their psychosis.¹⁵

Myths vs realities of filicide

Common myths vs the realities of filicide are noted in Table 2. There are issues with believing these myths. For example, if we believe that most parents who kill their child have mental illness, this conflates mental illness and child homicide in our minds as well as the mind of the public. This can lead to further stigmatization of mental illness, and a lack of help-seeking behaviors because parents experiencing psychiatric symptoms may be afraid that if they report their symptoms, their child will be removed by Child Protective Services. However, treated mental illness decreases the risks of child abuse, similar to how treating mental illness decreases risks of other types of violence.^20,21

Focusing on prevention

On a local level, we need to understand these tragedies to better understand prevention. To this end, across the United States, counties have Child Fatality Review teams.²² These teams are a partnership across sectors and disciplines, including professionals from health services, law enforcement, and social services—among others—working together to understand cases and consider preventive strategies and additional services needed within our communities.

Continue to: When conceptualizing prevention...

When conceptualizing prevention of child murder by parents, we can think of primary, secondary, and tertiary prevention. This means we want to encourage healthy families and healthy relationships within the family, as well as screening for risk and targeting interventions for families that have experienced difficulties, as well as for parents who have mental illness or substance use disorders.

Understanding the motive behind an individual committing filicide is also critical so that we do not conflate filicide and mental illness. Conflating these concepts leads to increased stigmatization and less help-seeking behavior.

Table 3^{3,4,7,18,22,23} describes the importance of understanding the motives for child murder by a parent in order to conceptualize appropriate prevention. Prevention efforts for 1 type of child murder will not necessarily help prevent murders that occur due to the other motives. Regarding prevention for fatal maltreatment cases, poor parenting skills, including inappropriate expressions of discipline, anger, and frustration, are common. In some cases, substance abuse is involved or the parent was acutely mentally unwell. Reporting to Child Protective Services can be helpful, but as previously noted, it is difficult to ascertain which cases will lead to a homicide. Recommendations from Child Fatality Review teams also are valuable.

Though many parents have frustrations with their children or thoughts of child harm, the act of filicide is rare, and individual cases may be difficult to predict. Regarding prediction, some mothers who committed filicide saw their psychiatrist within days to weeks before the murders.¹⁷ A small New Zealand study found that psychotic mothers reported no plans for killing their children in advance, whereas depressed mothers had contemplated the killing for days to weeks.²⁴

Several studies have asked mothers about thoughts of harming their child. Among mothers with colicky infants, 70% reported “explicit aggressive thoughts and fantasies” while 26% had “infanticidal thoughts” during a colic episode.²⁵ Another study²⁶ found that among depressed mothers of infants and toddlers, 41% revealed thoughts of harming their child. Women with postpartum depression preferred not to share infanticidal thoughts with their doctor but were more likely to disclose that they were having suicidal thoughts in order to get needed help.²⁷ Psychiatrists need to feel comfortable asking mothers about their coping skills, their suicidal thoughts, and their filicidal thoughts.^14,23,28 Screening and treatment of mental illness is critical. Postpartum psychosis is well-known to pose an elevated risk of filicide and suicide.²³ Obsessive-compulsive disorder may cause a parent to ruminate over ego-dystonic child harm but should be treated and the risk conceptualized very differently than in postpartum psychosis.^23,29 Screening for postpartum depression and appropriate treatment of depression during pregnancy and the postpartum period decrease risk.³⁰

Continue to: Regarding prevention of neonaticide...

Regarding prevention of neonaticide, Safe Haven laws, baby boxes, anonymous birth options, and increased contraceptive information and availability can help decrease the risk of this well-defined type of homicide.⁴ Safe Haven laws originated from Child Fatality Review teams.²⁴ Though each state has its own variation, in general, parents can drop off an unharmed unwanted infant into Safe Havens in their state, which may include hospitals, police stations, or fire stations. In general, the mother remains anonymous and has immunity from prosecution for (safe) abandonment. There are drawbacks, such as lack of information regarding adoption and paternal rights. Safe Haven laws do not prevent all deaths and all unsafe abandonments. Baby boxes and baby hatches are used in various nations, including in Europe, and in some places have been used for centuries. In anonymous birth options, such as in France, a mother is not identified but is able to give birth at a hospital. This can decrease the risk from unattended delivery, but many women with denial of pregnancy report that they did not realize when they were about to give birth.⁴

Bottom Line

Knowledge about the intersection of mental illness and filicide can help in prevention. Parents who experience mental health concerns should be encouraged to obtain needed treatment, which aids prevention. However, many other factors elevate the risk of child murder by parents.

Deaths of children who are killed by their parents often make the news. Cases of maternal infanticide may be particularly shocking, since women are expected to be selfless nurturers. Yet when a child is murdered, the most common perpetrator is their parent, and mothers and fathers kill at similar rates.¹

As psychiatrists, we may see these cases in the news and worry about the risks of our own patients killing their children. In approximately 500 cases annually, an American parent is arrested for the homicide of their child.² This is not even the entire story, since a large percentage of such cases end in suicide—and no arrest. This article reviews the reasons parents kill their children, and considers common characteristics of these parents, dispelling some myths, before discussing the importance of prevention efforts.

Types of child murder by parents

Child murder by parents is termed filicide. Infanticide has various meanings but often refers to the murder of a child younger than age 1. Approximately 2 dozen nations (but not the United States) have Infanticide Acts that decrease the penalty for mothers who kill their young child.³ Neonaticide refers to murder of the infant at birth or in the first day of life.⁴

Epidemiology and common characteristics

Approximately 15%—or 1 in 7 murders with an arrest—is a filicide.² The younger the child, the greater the risk, but older children are killed as well.² Internationally, fathers and mothers are found to kill at similar rates. For other types of homicide, offenders are overwhelmingly male. This makes child murder by parents the singular type of murder in which women and men perpetrate in equal numbers. Fathers are more likely than mothers to also commit suicide after they kill their children.⁵ The “Cinderella effect” refers to the elevated risk of a stepchild being killed compared to the risk for a biological child.⁶

In the general international population, mothers who commit filicide tend to have multiple stressors and limited resources. They may be socially isolated and may be victims themselves as well as potentially experiencing substance abuse.¹ Some mothers view the child they killed as abnormal.

Less research has been conducted about fathers who kill. Fathers are more likely to also commit partner homicide.^5,7 They are more likely to complete filicide-suicide and use firearms or other violent means.^5,7-9 Fathers may have a history of violence, substance abuse, and/or mental illness.⁷

Neonaticide

Mothers are the most common perpetrator of neonaticide.⁴ It is unusual for a father to be involved in a neonaticide, or for the father and mother to perpetrate the act together. Rates of neonaticide are considered underestimates because of the number of hidden pregnancies, hidden corpses, and the difficulty that forensic pathologists may have in determining whether a baby was born alive or dead.

Continue to: Perpetrators of neonaticide...

Perpetrators of neonaticide tend to be single, relatively young women acting alone. They often live with their parents and are fearful of the repercussions of being pregnant. Pregnancies are often hidden, with no prenatal care. This includes both denial and concealment of pregnancy.⁴ Perpetrators of neonaticide commonly lack a premorbid serious mental illness, though after the homicide they may develop anxiety, depression, posttraumatic stress disorder (PTSD), or adjustment disorder.⁴ (Individuals who unwittingly find a murdered baby’s corpse may also be at risk of PTSD.)

Hidden pregnancies may be due to concealment or denial of pregnancy.^10,11 Concealment of pregnancy involves a woman knowing she is pregnant, but purposely hiding from others. Concealment may occur after a period of denial of pregnancy. Denial of pregnancy has several subtypes: pervasive denial, affective denial, and psychotic denial. In cases of pervasive denial, the existence of the pregnancy and the pregnancy’s emotional significance is outside the woman’s awareness. Alternatively, in affective denial, she is intellectually aware that she is pregnant but makes little emotional or physical preparation. In the rarest form, psychotic denial, a woman with a psychotic disorder such as schizophrenia may intermittently deny her pregnancy. This may be correlated with a history of custody loss.^10,11 Unlike denial of other medical conditions, in cases of denial of pregnancy, there will exist a very specific point in time (delivery) when the reality of the baby confronts the woman. Risks in cases of hidden pregnancies include those from lack of prenatal care and an assisted delivery as well as neonaticide. An FBI study¹² of law enforcement files found most neonaticide offenders were single young women with no criminal or psychological history. A caveat is that in the rare cases in which a woman with psychotic illness commits neonaticide, she may have different characteristics from those generally reported.¹³

Motives

Fathers and mothers have a similar set of motives for killing their child (Table 1^13-15). Motives are critical to understand not only within forensics, but also for prevention. In performing assessments after a filicide, forensic psychiatrists must be mindful of gender bias.^7,16 Resnick¹⁵ initially described 5 motives based on his 1969 review of the world literature. Our work^5,17 has subsequently further explored these motives.

In child homicides from “fatal maltreatment,” the child has often been a chronic victim of abuse or neglect. National American data indicate that approximately 2 per 100,000 children are killed from child maltreatment annually. Of note in conceptualizing prevention, out of the same population of 100,000, there will be 471 referrals to Child Protective Services and 91 substantiated cases.¹⁸ However, only a minority of children who die from maltreatment had previous Child Protective Services involvement. While a child may be killed by fatal maltreatment at any age, one-half are younger than age 1, and three-quarters are younger than age 3.¹⁸ In rare cases, a parent who engages in medical child abuse (including factitious disorder imposed upon another) kills the child. Depending on the location and whether or not the death appeared to be intended, parents who kill because of fatal maltreatment might face charges of various levels of murder or manslaughter.

“Unwanted child” homicides occur when the parent has determined that they do not want to have the child, especially in comparison to another need or want. Unwanted child motive is the most common in neonaticide cases, occurring after a hidden pregnancy.⁴

Continue to: In "partner revenge" cases...

In “partner revenge” cases, parenting disputes, a custody battle, infidelity, or a difficult relationship breakup is often present. The parent wants to make the other parent suffer, and does so by killing their child. A parent may make statements such as “If I can’t have [the child], no one can,” and the child is used as a pawn.

The psychotic parent may believe that a terrible fate will befall their child, and they are killing them “gently.” For example, the parent may believe the child will be tortured or sex trafficked. Some parents may believe that their child has a devastating disease and think they would be better off dead. (Similar thinking of misguided altruism is seen in some cases of intimate partner homicide among older adults.¹⁹)

Alternatively, in rare cases of acutely psychotic filicide, parents with psychosis kill their child with no comprehensible motive. For example, they may be in a postictal state or may hear a command hallucination from God in the context of their psychosis.¹⁵

The advent of unprecedented technologies drastically altering the behavior of children and adolescents, compounded by prolonged isolation from a once-in-a-century pandemic, may have negatively impacted the normal connectivity of the human brain among youth, leading to the current alarming increase of depression, anxiety, and suicidality among this population.

The human brain is comprised of multiple large-scale networks that are functionally connected and control feelings, thoughts, and behaviors. As clinical neuroscientists, psychiatrists must consider the profound impact of a massive societal shift in human behavior on the functional connectivity of brain networks in health and disease. The advent of smartphones, social media, and video game addiction may have disrupted the developing brain networks in children and adolescents, leading to the current escalating epidemic of mental disorders in youth.

The major networks in the human brain include the default mode network (DMN), the salience network, the limbic system, the dorsal attention network, the central executive network, and the visual system.¹ Each network connects several brain regions. Researchers can use functional MRI to detect the connectivity of those networks. When blood flow increases concurrently across 2 or 3 networks, this indicates those networks are functionally connected.

There was an old “dogma” that brain regions use energy only when activated and being used. Hans Berger, who developed the EEG in 1929, noticed electrical activity at rest and proposed that the brain is constantly busy, but his neurology peers did not take him seriously.² In the 1950s, Louis Sokoloff noticed that brain metabolism was the same whether a person is at rest or doing math. In the 1970s, David Ingvar discovered that the highest blood flow in the frontal lobe occurred when a person was at rest.³ Finally, in 2007, Raichle et al⁴ used positron emission tomography scans to confirm that the frontal lobe is most active when a person is not doing anything. He labeled this phenomenon the DMN, comprising the medial fronto-parietal cortex, the posterior cingulate gyrus, the precuneus, and the angular gyrus. Interestingly, the number of publications about the DMN has skyrocketed since 2007.

The many roles of the DMN

Ongoing research has revealed that the DMN is most active at rest, and its anatomical hubs mediate several key functions⁵:

• Posterior cingulate gyrus (the central core of the DMN): remembering the past and thinking about the future
• Medial prefrontal cortex: autobiographical memories, future goals and events, reflecting on one’s emotional self, and considering decisions about family members
• Dorsal medial subsystem: thinking about others, determining and inferring the purpose of other people’s actions
• Temporo-parietal junction: reflecting on the beliefs and emotions of others (known as “theory of mind”⁶)
• Lateral parietal junction: retrieval of social and conceptual knowledge
• Hippocampus: forming new memories, remembering the past, imagining the future
• Posterior-inferior parietal lobe: junction of auditory, visual, and somatic sensory information and attention
• Precuneus: Visual, sensory-motor, and attention.

Many terms have been used to describe the function of the DMN, including “daydreaming,” “auto-pilot,” “mind-wondering,” “reminiscing,” “contemplating,” “self-reflection,” “the neurological basis of the self,” and “seat of literary creativity.”

Psychiatric consequences of DMN deactivation

When another brain network, the attention network (which is also referred to as the task-positive network), is activated consciously and volitionally to perform a task that demands focus (such as text messaging, playing video games, or continuously interacting with social media sites), DMN activity declines.

Continue to: The DMN does not exist...

The DMN does not exist in infants, but starts to develop in childhood.⁷ It is enhanced by exercise, daydreaming, and sleep, activities that are common in childhood but have declined drastically with the widespread use of smartphones, video games, and social media, which for many youth occupy the bulk of their waking hours. Those tasks, which require continuous attention, deactivate the DMN. In fact, research has shown that addictive behavior decreases the connectivity of the DMN and suppresses its activity.⁸ Most children and adolescents can be regarded as essentially addicted to social media, text messaging, and video games. Unsurprisingly, serious psychiatric consequences follow.⁹

DMN dysfunction has been reported in several psychiatric conditions, including depression, posttraumatic stress disorder, autism, schizophrenia, anxiety, obsessive-compulsive disorder, and substance use.^10-12 Impaired social interactions and communications, negative ruminations, suicidal ideas, and impaired encoding of long-term memories are some of the adverse effects of DMN dysfunction. The good news is that the DMN’s connectivity and functioning can be modulated and restored by meditation, mentalizing, exercise, psychotherapy, antidepressants, and psychedelics.^13,14

The lockdown and stress of the COVID-19 pandemic added insult to injury and exacerbated mental illness in children by isolating them from each other and intensifying their technological addiction to fill the void of isolation. This crisis in youth mental health continues unabated, and calls for action to prevent grim outcomes. DMN dysfunction in youth can be reversed with treatment, but access to mental health care has become more challenging due to workforce shortages and insurance restrictions. Psychiatrists and parents must work diligently to treat psychiatrically affected youth, which has become a DaMN serious problem…

Those tasks, which require continuous attention, deactivate the DMN. In fact, research has shown that addictive behavior decreases the connectivity of the DMN and suppresses its activity.⁸ Most children and adolescents can be regarded as essentially addicted to social media, text messaging, and video games. Unsurprisingly, serious psychiatric consequences follow.⁹

DMN dysfunction has been reported in several psychiatric conditions, including depression, posttraumatic stress disorder, autism, schizophrenia, anxiety, obsessive-compulsive disorder, and substance use.^10-12 Impaired social interactions and communications, negative ruminations, suicidal ideas, and impaired encoding of long-term memories are some of the adverse effects of DMN dysfunction. The good news is that the DMN’s connectivity and functioning can be modulated and restored by meditation, mentalizing, exercise, psychotherapy, antidepressants, and psychedelics.^13,14

The lockdown and stress of the COVID-19 pandemic added insult to injury and exacerbated mental illness in children by isolating them from each other and intensifying their technological addiction to fill the void of isolation. This crisis in youth mental health continues unabated, and calls for action to prevent grim outcomes. DMN dysfunction in youth can be reversed with treatment, but access to mental health care has become more challenging due to workforce shortages and insurance restrictions. Psychiatrists and parents must work diligently to treat psychiatrically affected youth, which has become a DaMN serious problem…

The Diagnosis: Actinic Prurigo

Actinic prurigo is an idiopathic photodermatosis triggered by UV exposure that primarily affects sun-exposed areas of the skin.^1,2 It typically presents as pruritic papules, plaques, and nodules, with most patients also experiencing oral tingling and pain.³ In more severe cases, it can progress to include conjunctival disease, scarring, and cheilitis.¹ A study of ocular findings among children with actinic pruritus reported that photophobia was one of the most important features,⁴ which was present in our patient. The face, especially over the zygomatic arches, nasal bridge, and lower lip, commonly is affected.1 Secondary lichenification or eczematization may occur.⁵ In our patient, the combination of conjunctivitis, cheilitis, and an eruption on sun-exposed skin were crucial in making the diagnosis.

Most cases present in patients younger than 10 years. It most commonly is seen in American Indians in North America, Central America, and South America.² After the diagnosis was considered in our patient, the family was asked about their ancestry and confirmed that both of the patient’s maternal and paternal grandparents were of American Indian descent. There also is a strong genetic component; the HLA-DR4 allele variant is present in 90% of cases, especially DRB1*0407, which is seen in 60% of cases.^1,6 In our patient, testing revealed HLA-DR4, DRB1*04 positivity. We further hypothesized that his mother’s photosensitive rash may have been actinic prurigo as opposed to polymorphous light eruption, which could explain the lack of response to hydroxychloroquine.

The diagnosis of actinic prurigo usually is made clinically. A skin biopsy typically is not necessary but would show hyperkeratosis, spongiosis, and acanthosis with a lymphocytic perivascular infiltrate. Biopsies of the lip classically show lymphoid germinal centers in the lamina propria, which can help distinguish actinic prurigo from polymorphous light eruption.¹

In our patient, the differential diagnosis included polymorphous light eruption, connective tissue disease such as lupus erythematosus or dermatomyositis, porphyria such as erythropoietic protoporphyria, and allergic contact dermatitis. Polymorphous light eruption was ruled out by the oral and ocular manifestations, which are not atypical for this diagnosis. The patient’s laboratory results displayed unremarkable antinuclear antibodies, creatine kinase, aldolase, and extractable nuclear antigens, which made connective tissue disease unlikely. Furthermore, a porphyria screen for total plasma porphyrins and whole blood protoporphyrin was negative, which helped rule out porphyria. Allergic contact dermatitis seemed less likely given the lack of improvement with topical steroids. Overall, the clinical presentation in a patient with relevant family ancestry and HLA-DR4 positivity supported a diagnosis of actinic prurigo.⁷

To manage the condition in our patient, strict photoprotection was recommended as well as the application of triamcinolone ointment 0.025% to the affected areas twice daily until the skin symptoms improved. For acute flares, other treatment considerations include topical tacrolimus, oral antihistamines, and oral corticosteroids. Some success has been reported with cyclosporine and azathioprine. For severe disease, thalidomide is the recommended treatment; it is effective in pediatric patients at dosages of 50 to 100 mg daily, but the dose has not yet been standardized for this age group.^8,9 Many adult patients initially are controlled with 100 to 200 mg daily, which can be tapered down to a dosage of 25 to 50 mg weekly with few adverse effects; however, the overall substantial side effects of thalidomide limit its use in both pediatric and adult populations.^1,2 Newer studies have suggested promising results with dupilumab, especially when actinic prurigo presents with high IgE levels or eosinophils on histology.^7,10 In our patient, the IgE level was normal.
