Expert spotlights telltale clinical signs of xeroderma pigmentosum
AUSTIN, TEX. – If a child presents with acute (XP), a rare autosomal recessive disorder.
Other telltale symptoms of XP include the presence of skin cancer at an early age and a large number of skin cancers.
At the annual meeting of the Society for Pediatric Dermatology, John J. DiGiovanna, MD, described XP as a disorder of genomic instability, which has no cure. It’s caused by a mutation in genes XPA through XPG and the XP variant (XPV) gene. “The genome controls our genes, and UV rays damage DNA,” said Dr. DiGiovanna, who is a senior research physician at the National Cancer Institute’s Laboratory of Cancer and Biology and Genetics, Bethesda, Md. “This damage from UV radiation is similar to damage from chemical agents that form DNA adducts, such as cigarette smoke and certain chemotherapy agents such as cisplatinum.”
XP patients present with or without acute burning after minimal sun exposure, while children with both subtypes develop “freckling” by the time they reach 2 years of age. Dr. DiGiovanna pointed out that lentigo maligna lesions associated with XP resemble freckles at first glance, yet they vary in size, intensity, and border. Meanwhile, freckles in healthy patients are similar in size, are light tan in color, and have a regular border.
“The burning with minimal sun exposure that occurs during childhood leads to pigmentary changes, atrophy, xerosis, and telangiectasias,” he said. A follow-up analysis of 106 XP patients admitted to the National Institutes of Health between 1971 and 2009 found that patients were diagnosed with their first nonmelanoma skin cancer at a median age of 9 years, compared with age 67 among those in the general population (J Med Genet 2011 Mar;48[3]:168-76). “This is a 58-year decrease in age at risk, which is a 10,000-fold increase in skin cancer,” said Dr. DiGiovanna, who was one of the study authors.
Melanoma also occurs at an earlier age among XP patients – a median age of 22 years, compared with a median of 55 years in the general population. “In the general population, melanoma occurs at a younger age than nonmelanoma skin cancer, while in the XP population, melanoma occurs at an older age,” he said. “This is giving us a good biologic lesson that the melanoma induction mechanism must be different from nonmelanoma skin cancer.”
He recalled one XP patient who was followed by NIH researchers for 4 decades. She worked in a doctor’s office and drove a car, but developed progressive neurologic degeneration and died at the age of 40. “This was not due to unrepaired UV damage, but there are other agents which damage other neurons,” Dr. DiGiovanna explained. “Over time, what you get is a decrease in brain volume, an increase in the brain ventricles, and a loss of brain tissue. At postmortem examination, her brain was of infantile size, compared with that of an equivalent 40-year-old. This is a disease of neuronal loss, and it’s progressive. Only about 20%-25% of XP patients experience neural degeneration.”
Management of XP involves strict sun avoidance, including use of a portable UV meter and many layers of UV protection, including application of sunscreen, wearing protective clothing, sunglasses, hats, and face shields, and the use of UV-blocking window film, LED lights, and a vitamin D diet or oral supplementation. Affected individuals also require frequent skin monitoring by the patients and their family members, frequent dermatologic exams by clinicians, biopsy of suspicious lesions, removal of any skin cancers found, field treatments with agents such as 5-fluorouracil and imiquimod, and chemoprevention with oral retinoids for patients who are actively developing large numbers of new lesions (N Engl J Med. 1988 Jun23;318[25]:1633-7).
“Probably the most important thing you can do is refer them to patient support groups,” Dr. DiGiovanna said. “They are present in many countries and can help them manage the day-to-day issues of their condition.” Support groups based in North America include the XP Family Support Group, XP Society, and XP Grupo Luz De Esperanza.

REPORTING FROM SPD 2019
Two uveitis treatment options yield similar success
in an international, multicenter, open-label, randomized trial.
“The findings of this trial have implications for clinical practice because they provide scientific justification that mycophenolate mofetil is not more effective than methotrexate as a corticosteroid-sparing immunosuppressive therapy for uveitis,” wrote S.R. Rathinam, MD, PhD, of Aravind Eye Hospital and Postgraduate Institute of Ophthalmology, Madurai, India, and colleagues.
Although corticosteroid therapy is the first-line treatment for uveitis, adverse effects limit long-term use. Mycophenolate mofetil and methotrexate are options for corticosteroid-sparing immunosuppressive therapy for uveitis, but their effectiveness has not been compared until the current study, they said.
In the First-line Antimetabolites as Steroid-sparing Treatment (FAST) trial published Sept. 10 in JAMA, the researchers randomized 216 adults with uveitis (a total of 407 eyes with uveitis) to 25 mg of weekly oral methotrexate or 1.5 g of twice-daily oral mycophenolate mofetil at nine referral eye care centers in India, the United States, Australia, Saudi Arabia, and Mexico; the investigators were masked to the treatment assignment.
Patients with treatment success continued taking their randomized medication for another 6 months. If treatment failed, patients switched to the other antimetabolite with another 6-month follow-up. Overall, 84%-93% in each group had bilateral uveitis. Forty-six patients (21%) had intermediate uveitis only or anterior uveitis and intermediate uveitis, and 170 patients (79%) had posterior uveitis or panuveitis. The median age of the patients was 36 years in the methotrexate group and 41 years in the mycophenolate group; other demographic characteristics were similar between the groups.
Overall, 64 patients given methotrexate (67%) and 56 of those given mycophenolate (57%) achieved treatment success at 6 months. Treatment success included inflammation control defined as “less than or equal to 0.5+ anterior chamber cells by Standardization of Uveitis Nomenclature criteria, less than or equal to 0.5+ vitreous haze clinical grading using the National Eye Institute scale, and no active retinal or choroidal lesions,” as well as needing no more than 7.5 mg of prednisone daily and two drops or less of prednisolone acetate 1% per day, and reporting no intolerability or safety concerns requiring study discontinuation.
Adverse events were similar between the groups. The most common nonserious adverse events were fatigue and headaches, and the most common nonserious laboratory adverse event was elevated liver enzymes. Fourteen serious adverse events occurred during the study period; three in the methotrexate group and two in the mycophenolate group were deemed drug related and all were elevated liver function tests.
The study findings had several limitations, including lack of masking of the patients to the medication and an inability to compare between types of uveitis, the researchers noted. Avenues for further research include whether one of the drugs is more effective based on the uveitis subtype, they added.
The study was supported in part by the National Eye Institute and study drugs were provided by the University of California San Francisco Pharmacy. Dr. Rathinam disclosed grants from Aravind Eye Hospital, and several coauthors disclosed relationships with AbbVie, Allergan, Novartis, Novotech, and Bayer.

Measles cases continue to decline
according to the Centers for Disease Control and Prevention.
A total of 24 measles cases were confirmed in August, and the total for the year is now 1,241 cases in 31 states. Only seven of those cases were added during the most recent reporting week, which ended Sept. 5, but five were older cases that had just been reported, the CDC said Sept. 9.
With the ending of the measles outbreak in New York, announced Sept. 3, the largest of the three remaining active outbreaks in the country is in Rockland County, N.Y., just north of the city, which has reported 312 cases since it began in 2018.
The two other outbreaks are located in El Paso, Tex., where six cases have been reported so far, and Wyoming County in western New York State, where five cases have occurred.

FDA issues warning to JUUL on illegal marketing of e-cigarettes
, citing violation of the Federal Food, Drug, and Cosmetic Act.
According to the letter, JUUL has marketed its e-cigarettes and e-liquids as modified-risk tobacco products without receiving FDA authorization to do so. JUUL’s labeling, advertising, and other consumer-oriented activities to this effect could reasonably lead consumers to believe that JUUL products represent a lower risk of tobacco-related disease, compared with other tobacco products; that they contain a reduced level of a substance; and that they are free of a particular substance or substances.
As evidence, the letter cited testimony given at a July 2019 hearing held by the Subcommittee on Economic and Consumer Policy of the Committee on Oversight and Reform of the House of Representatives, in which a representative from JUUL, speaking to students at a school presentation, said that JUUL products were “much safer than cigarettes” and that the “FDA would approve it any day,” that JUUL products were “totally safe,” that a student “should mention JUUL to his [nicotine-addicted] friend ... because that’s a safer alternative than smoking cigarettes, and it would be better for the kid to use,” and that the FDA “was about to come out and say it [JUUL] was 99% safer than cigarettes ... and that ... would happen very soon.”
In addition, a “Letter from the CEO” that appeared on the JUUL website and was emailed to a parent in response to her complaint that the company sold JUUL products to her child stated that “[JUUL’s] simple and convenient system incorporates temperature regulation to heat nicotine liquid and deliver smokers the satisfaction that they want without the combustion and the harm associated with it.”
In a related press release, acting FDA Commissioner Ned Sharpless, MD, said that “regardless of where products like e-cigarettes fall on the continuum of tobacco product risk, the law is clear that, before marketing tobacco products for reduced risk, companies must demonstrate with scientific evidence that their specific product does in fact pose less risk or is less harmful. JUUL has ignored the law, and very concerningly, has made some of these statements in school to our nation’s youth.”
The FDA has requested a response from JUUL within 15 working days of the letter’s issue. Failure to comply with the Federal Food, Drug, and Cosmetic Act could result in the FDA’s initiating further actions such as civil money penalties, seizure, and/or injunction.

Chemotherapy may raise CVD risk in pediatric cancer survivors
Pediatric cancer survivors have a higher likelihood of experiencing a cardiac event, developing diabetes, or having hypertension at a median 10-year follow-up, according to results from a recent research letter published in Circulation.
Ashna Khanna of the University of Toronto and colleagues identified 7,289 pediatric patients in the Pediatric Oncology Group of Ontario Networked Information System who were diagnosed with cancer at median age of 7 years old, who were treated between 1987 and 2010, and who were cancer survivors for 5 years. Each patient was matched to five cancer-free control subjects who were a median of 24 years old at the 10-year follow-up (36,205 cancer-free individuals). The researchers studied whether pediatric cancer survivors experienced cardiac events, such as heart failure, arrhythmia, pericardial disease, valvular disease, or coronary artery disease. They also evaluated the incidence of diabetes and hypertension in each group.
Of the children who survived cancer, 2.8% (n = 203) experienced at least one cardiac event versus 0.9% of controls (P less than .001). The cancer survivors experienced 3.2 cardiac events per 1,000 person-years (95% confidence interval, 2.8-3.6), compared with the control group in which there was a rate of 0.9 cardiac events per 1,000 person-years (95% CI, 0.9-1.9).
With regard to cardiovascular disease (CVD) risk, associated factors included cancer relapse or subsequent cancer (hazard ratio, 1.7; 95% CI, 1.1-2.7) and a 250-mg/m2 or greater dose of doxorubicin-equivalent anthracycline chemotherapy, compared with a dose of less than 250 mg/m2 or no anthracycline chemotherapy (HR, 2.0; 95% CI, 1.4-2.9). Patients who developed diabetes mellitus before a CVD diagnosis were also at higher risk of CVD (HR, 3.0; 95% CI, 1.6-5.8).
Heart failure risk was also statistically significant in patients with relapse and subsequent childhood cancer (HR, 2.0; 95% CI, 1.1-3.7), a 250-mg/m2 or greater dose of doxorubicin-equivalent anthracycline chemotherapy (HR, 8.6; 95% CI, 4.5-16.6), diabetes (HR, 4.3; 95% CI, 1.8-10.7), and hypertension (HR, 3.1; 95% CI, 1.3-7.9).
“While anthracycline chemotherapy may induce heart disease, many patients require this cancer treatment to survive,” Paul Nathan, MD, of the Hospital for Sick Children in Canada and a study coauthor said in a statement. “Doctors should address heart disease risk factors – such as diabetes and hypertension – that can be modified.”

Pediatric cancer survivors have a higher likelihood of experiencing a cardiac event, developing diabetes, or having hypertension at a median 10-year follow-up, according to results from a recent research letter published in Circulation.
Ashna Khanna of the University of Toronto and colleagues identified 7,289 pediatric patients in the Pediatric Oncology Group of Ontario Networked Information System who were diagnosed with cancer at median age of 7 years old, who were treated between 1987 and 2010, and who were cancer survivors for 5 years. Each patient was matched to five cancer-free control subjects who were a median of 24 years old at the 10-year follow-up (36,205 cancer-free individuals). The researchers studied whether pediatric cancer survivors experienced cardiac events, such as heart failure, arrhythmia, pericardial disease, valvular disease, or coronary artery disease. They also evaluated the incidence of diabetes and hypertension in each group.

U.S. and African programs aim to improve understanding, treatment of sickle cell disease
Researchers are leading several programs designed to serve the sickle cell community in the United States and sub-Saharan Africa, officials at the National Heart, Lung, and Blood Institute (NHLBI) said during a recent webinar.
One program based in the United States is focused on building a registry for patients with sickle cell disease (SCD) and conducting studies designed to improve SCD care. Another program involves building “an information-sharing network and patient-powered registry” in the United States.
The programs in sub-Saharan Africa were designed to establish a database of SCD patients, optimize the use of hydroxyurea in children with SCD, and aid genomic studies of SCD.
W. Keith Hoots, MD, director of the Division of Blood Diseases and Resources at NHLBI, began the webinar with an overview of the programs in sub-Saharan Africa. He described four programs with sites in nine countries (Angola, Cameroon, Democratic Republic of Congo, Ghana, Kenya, Nigeria, South Africa, Tanzania, and Uganda).
SPARCO and SADaCC
Dr. Hoots outlined the scope the Sickle Pan-African Research Consortium (SPARCO) and the Sickle Africa Data Coordinating Center (SADaCC), both part of the Sickle In Africa consortium.
A major goal of SPARCO and SADaCC is to create a Research Electronic Data Capture database that encompasses SCD patients in sub-Saharan Africa. As of April 2019, the database included 6,578 patients. The target is 13,000 patients.
Other goals of SPARCO and SADaCC are to “harmonize” SCD phenotype definitions and ontologies, create clinical guidelines for SCD management in sub-Saharan Africa, plan future cohort studies, and develop programs for newborn screening, infection prevention, and increased use of hydroxyurea.
“So far, they’re well along in establishing a registry and a database system,” Dr. Hoots said. “They’ve agreed on the database elements, phenotype definitions, and ontologies, they’ve developed some regionally appropriate clinical management guidelines, and they’ve begun skills development on the ground at all respective sites.”
REACH
Another program Dr. Hoots discussed is Realizing Effectiveness Across Continents With Hydroxyurea (REACH), a phase 1/2 pilot study of hydroxyurea in children (aged 1-10 years) with SCD in sub-Saharan Africa.
The goals of REACH are to determine the optimal dose of hydroxyurea in this population; teach African physicians how to administer hydroxyurea; assess the safety, feasibility, and benefits of hydroxyurea; study variability in response to hydroxyurea; gather data for the Research Electronic Data Capture database; and establish a research infrastructure for future collaborations.
Results from more than 600 children enrolled in REACH were presented at the 2018 annual meeting of the American Society of Hematology and simultaneously published in the New England Journal of Medicine (N Engl J Med. 2019 Jan 10; 380[2]:121-31).
SickleGenAfrica
SickleGenAfrica is part of the H3Africa consortium and aims to “build capacity for genomic research in Africa,” Dr. Hoots said.
Under this program, researchers will conduct three studies to test the hypothesis that genetic variation affects the defense against hemolysis and organ damage in patients with SCD. The researchers will study existing cohorts of SCD patients including children and adults.
Other goals of SickleGenAfrica are to establish a molecular hematology and sickle cell mouse core, an SCD biorepository core, a bioinformatics core, and an administrative core for the coordination of activities. The program will also be used to train “future science leaders” in SCD research, Dr. Hoots said.
SCDIC
Cheryl Anne Boyce, PhD, chief of the Implementation Science Branch at the Center for Translation Research and Implementation Science at NHLBI, discussed the United States–based Sickle Cell Disease Implementation Consortium (SCDIC).
“The goals of the consortium are to develop a registry in collaboration with other centers and the NHLBI, as well as a needs-based community assessment of the barriers to care for subjects with sickle cell disease,” Dr. Boyce said. “We also wanted to design implementation research studies that address the identified barriers to care.”
Dr. Boyce said the SCDIC’s registry is open to patients aged 15-45 years who have a confirmed SCD diagnosis, speak English, and are able to consent to and complete a survey. The registry has enrolled almost 2,400 patients from eight centers over 18 months.
The SCDIC has also performed a needs assessment that prompted the development of three implementation research studies. The first study involves using mobile health interventions to, ideally, increase patient adherence to hydroxyurea and improve provider knowledge of hydroxyurea.
With the second study, researchers aim to improve the care of SCD patients in the emergency department by using an inpatient portal. The goals of the third study are to establish a standard definition for unaffiliated patients, conduct a needs assessment for this group, and develop an intervention that can provide these patients with guideline-based SCD care.
Get Connected
Kim Smith-Whitley, MD, director of the Comprehensive Sickle Cell Center at the Children’s Hospital of Philadelphia and a board member of the Sickle Cell Disease Association of America (SCDAA), described Get Connected, “an information-sharing network and patient-powered registry” created by SCDAA.
Dr. Smith-Whitley said one purpose of Get Connected is to provide a network that facilitates “the distribution of information related to clinical care, research, health services, health policy, and advocacy.”
The network is open to families living with SCD and sickle cell trait, SCDAA member organizations, health care providers, clinical researchers, and community-based organizations.
Get Connected also includes a registry for SCD patients that stores information on their diagnosis and treatment, as well as online communities that can be used to share information and provide psychosocial support.
Thus far, Get Connected has enrolled 6,329 individuals. This includes 5,100 children and adults with SCD, 652 children and adults with sickle cell trait, and 577 nonpatients.
The webinar presenters did not disclose any conflicts of interest.

Pediatric HSCT recipients still risking sunburn
Young people who have received allogeneic hematopoietic stem cell transplants (HSCTs) are more likely to wear hats, sunscreen and other sun protection, but still intentionally tan and experience sunburn at the same rate as their peers, new research suggests.
In a survey‐based, cross‐sectional cohort study, researchers compared sun-protection behaviors and sun exposure in 85 children aged 21 years and younger who had undergone HSCT and 85 age-, sex-, and skin type–matched controls. The findings were published in Pediatric Dermatology.
HSCT recipients have a higher risk of long-term complications such as skin cancer, for which sun exposure is a major modifiable environmental risk factor.
“Therefore, consistent sun avoidance and protection as well as regular dermatologic evaluations are important for HSCT recipients,” wrote Edward B. Li, PhD, from Harvard Medical School, Boston, and coauthors.
The survey found no significant difference between the transplant and control group in the amount of intentional sun exposure, such as the amount of time spent outside on weekdays and weekends during the peak sun intensity hours of 10 a.m. and 4 p.m. More than one in five transplant recipients (21.2%) reported spending at least 3 hours a day outside between 10 a.m. and 4 p.m. on weekdays, as did 36.5% of transplant recipients on weekends.
There were also no significant differences between the two groups in terms of time spent tanning, either in the sun or in a tanning bed. Additionally, a similar number of transplant recipients and controls experienced one or more red or painful sunburns in the past year (25.9% vs. 27.1%).
However, transplant patients did practice better sun protection behaviors than did the control group, with 60% reporting that they always wore sunscreen, compared with 29.4% of controls. The transplant recipients were also significantly more likely to wear sunglasses and a hat and to stay in the shade or use an umbrella.
“While these data may reflect that HSCT patients are not practicing adequate sun avoidance, it may also suggest that these long‐term survivors are able to enjoy being outdoors as much as their peers and have a similar desire to have a tanned appearance,” the researchers wrote. “While a healthy and active lifestyle should be encouraged for all children, our results emphasize the need for pediatric HSCT survivors to be educated on their increased risk for UV‐related skin cancers, counseled on avoidance of intentional tanning, and advised on the importance of sun protection behaviors in an effort to improve long-term outcomes.”
The researchers noted that transplant recipients were significantly more likely to have had a full body skin exam from a health care professional than were individuals in the control group (61.2% vs. 4.7%) and were more likely to have done a self-check or been checked by a partner in the previous year.
The study was supported by the Society for Pediatric Dermatology, the Dermatology Foundation, the National Institutes of Health, and the Dr. Miriam and Sheldon G. Adelson Medical Research Foundation. One author declared a financial interest in a company developing a dermatological product. No other conflicts of interest were declared.

“While these data may reflect that HSCT patients are not practicing adequate sun avoidance, it may also suggest that these long‐term survivors are able to enjoy being outdoors as much as their peers and have a similar desire to have a tanned appearance,” the researchers wrote. “While a healthy and active lifestyle should be encouraged for all children, our results emphasize the need for pediatric HSCT survivors to be educated on their increased risk for UV‐related skin cancers, counseled on avoidance of intentional tanning, and advised on the importance of sun protection behaviors in an effort to improve long-term outcomes.”
The researchers noted that transplant recipients were significantly more likely to have had a full body skin exam from a health care professional than were individuals in the control group (61.2% vs. 4.7%) and were more likely to have done a self-check or been checked by a partner in the previous year.
The study was supported by the Society for Pediatric Dermatology, the Dermatology Foundation, the National Institutes of Health, and the Dr. Miriam and Sheldon G. Adelson Medical Research Foundation. One author declared a financial interest in a company developing a dermatological product. No other conflicts of interest were declared.

FROM PEDIATRIC DERMATOLOGY
Wrong cuff size throws off pediatric BP by 5 mm Hg
NEW ORLEANS – according to investigators from Columbia University in New York.
There are five cuff sizes in pediatrics, depending on a child’s arm circumference. Ideally, it’s measured beforehand so the right cuff size is used, but that doesn’t always happen in everyday practice.
Sometimes, clinicians just estimate arm size before choosing a cuff or opt for the medium-sized cuff in most kids; other times, the correct size has gone missing, said lead investigator Ruchi Gupta Mahajan, MD, a pediatric nephrology fellow at Columbia.
For those situations, she and her colleagues wanted to quantify how much the wrong cuff size throws off blood pressure readings in children, something that’s been done before in adult medicine, but not in pediatrics.
The idea was to give clinicians a decent estimate of true blood pressure even when the cuff isn’t quite right, something that’s particularly important with an increasing emphasis on catching hypertension as early as possible in children, she said.
After her subjects sat quietly for 10 minutes, Dr. Mahajan took automated blood pressure readings on 137 children; once with the right cuff size, once with a cuff one size too small, and once with a cuff one size too big, with a minute apart between readings.
The children were aged 4-12 years old and were in the office for wellness visits. None of them had heart or kidney disease, and none were on steroids or any other medications that affect blood pressure. There were a few more boys than girls, and almost all the children were Hispanic.
Overall, systolic blood pressure was an average of 5 mm Hg less with the larger cuff and 5 mm Hg more with the smaller cuff. The finding was the same in both girls and boys, and it held across age groups and in under, over, and normal weight children.
“I was really surprised there was no difference between ages, 4-12 years of age, its just a single number: 5. [Even] if [you] don’t have the appropriate cuff size,” the finding means that it’s still possible to have a good estimate of blood pressure, Dr. Mahajan said at the joint scientific sessions of the American Heart Association (AHA) Council on Hypertension, AHA Council on Kidney in Cardiovascular Disease, and American Society of Hypertension.
Meanwhile, cuff size didn’t have any statistically significant effect on diastolic pressure.
There was no outside funding for the study and Dr. Mahajan reported having no disclosures.

REPORTING FROM JOINT HYPERTENSION 2019
No ‘one size fits all’ approach to managing severe pediatric psoriasis
AUSTIN, TEX. – The way Kelly M. Cordoro sees it, the most for which patient.
“You can look up the dosing and frequency of these drugs; all of that’s available,” she said at the annual meeting of the Society for Pediatric Dermatology. “But how do we think about which drug for which patient? What are the considerations?”
Dr. Cordoro, professor of dermatology and pediatrics at the University of California, San Francisco, described psoriasis as an autoamplifying inflammatory cascade involving innate and adaptive immunity and noted that various components of that cascade represent treatment targets. “We don’t have a true comprehension of the pathophysiology of psoriasis, but as we learn the pathways, we’re targeting them,” she said. “You can target keratinocyte proliferation with drugs like retinoids and phototherapy. You can broadly target T cells, neutrophils, and dendritic cells with methotrexate, cyclosporine, and phototherapy. The newer drugs target the cytokine milieu, including TNF [tumor necrosis factor]–alpha, IL [interleukin]–17A, IL-12, and IL-23.”
There is no one right answer for which drug to prescribe, she continued, except in the cases of certain comorbidities, contraindications, and genetic variants. “For example, if a patient has psoriatic arthritis, then you have methotrexate and all of the biologics that might be disease modifying,” she said. “If a patient has inflammatory bowel disease, it’s critical to know that IL-17 inhibitors will flare that disease, but anti-TNF and IL-12 and IL-23 inhibitors are okay. If a patient has liver and kidney disease, you want to avoid methotrexate and cyclosporine. If there’s a female of childbearing potential you want to be very cautious with using retinoids. I think the harder question for us is, How about the rest of the patients?”
In addition to a drug’s mechanism of action, patient- and family-related factors play a role in deciding which agent to use. For example, does the patient prefer an oral or an injectable agent? Is the patient able to travel to a phototherapy center? Is it feasible for the family to manage visits for lab work and direct clinical monitoring? Does the family have a high level of health literacy and are you communicating with them in ways that facilitate shared decision making?
“The best way to choose a systemic therapy is to develop an individualized assessment of overall disease burden,” said Dr. Cordoro, who is also division chief of pediatric dermatology at UCSF. “Include psychological burden and subjective data in addition to objective measures like body surface area. Look for triggers. Infants are more commonly affected by viral infections and, in a subset, monogenic forms of psoriasis such as deficiency of interleukin 1 receptor antagonist [DIRA]. In general, we try to take a conservative approach in the developing child. As children hit early adolescence and become post pubertal, you have to start thinking about the psychosocial impact [of psoriasis], and we have to start treating patients with the consideration that chronic uncontrolled inflammation can potentially lead to comorbidities down the road. We see this in adults with severe psoriasis and early onset cardiovascular disease, the so-called psoriatic march from chronic inflammation to cardiovascular disease.”
Dr. Cordoro advises clinicians to rethink the conventional “therapeutic ladder” concept and embrace the idea of “finding the right tool for the job right now.” If a patient presents with a flare from a known trigger such as a strep infection, “maybe you want to treat with something more conservative,” she said. “Once you treat, and if the trigger has been managed, they might be better. But some patients will need the most aggressive treatment right out of the gate.”
Tried and true systemic therapies for psoriasis include methotrexate, cyclosporine, acitretin, and phototherapy, but none is approved by the Food and Drug Administration for use in children. “These drugs have decades of experience behind them,” Dr. Cordoro said. “Methotrexate is slow to start but has a sustained profile, so if you can get the patient to respond, that response tends to persist. Methotrexate also prevents the formation of antidrug antibodies, which is important if you are considering use of a biologic agent later on.”
Cyclosporine is best if you need a rapid rescue drug to get the disease under control before moving on to other options. “One in four patients relapse once cyclosporine is discontinued, so the benefit may not be as sustained as with methotrexate,” she said. “Acitretin is a really nice choice when you can’t or don’t want to immunosuppress the patient, and phototherapy is good if you can get it. The advantages of systemic therapies are that they’re easy on, easy off, and you can combine medications in severe situations. Almost all of these drugs can be combined with another, with few exceptions. I would caution that over immunosuppression is the biggest risk ... so this must be done carefully and only when necessary.”
Biologic agents such as TNF inhibitors and IL-12/23 inhibitors are playing an increasing role in pediatric psoriasis. They can be expensive and difficult for some insurance plans to cover, but offer the convenience of better efficacy and less frequent lab monitoring than conventional systemics. In the United States, etanercept and ustekinumab are approved for moderate to severe pediatric plaque psoriasis in patients as young as age 4 and 12 years, respectively. TNF inhibitors have accumulated the most data in children, while data are accumulating in trials of IL-17 inhibitors, IL-23 inhibitors, and PDE4 inhibitors.
“These drugs have reassuring safety profiles; low rates of infection and adverse reactions,” Dr. Cordoro said of biologic agents. “They’ve changed the landscape completely because now the expectation is complete or near-complete clearance. In contrast to the systemic agents, which may be started and stopped repeatedly, you need to think about continuous therapy, because these drugs are immunogenic,” she noted. “Whether antibodies against them become neutralizing or not is a different case. If a patient does have antibodies, it does not mean you have to stop the drug. Dose escalation can help. Increasing frequency of use of the drug can help, but patients will develop antibodies and it may result in loss of efficacy or reactions to the drug,” she added.
“When you’re thinking about using a biologic agent, think about patients who are chronic, moderate to severe, and who will need more long-term therapy. Most importantly, treatment should be individualized, as there is no ‘one size fits all’ approach.”

EXPERT ANALYSIS FROM SPD 2019
Vape lung disease cases exceed 400, 3 dead
Vitamin E acetate is one possible culprit in the mysterious vaping-associated lung disease that has killed three patients, sickened 450, and baffled clinicians and investigators all summer.
Another death may be linked to the disorder, officials said during a joint press briefing held by the Centers for Disease Control and Prevention and the Food and Drug Administration. In all, 450 potential cases have been reported and e-cigarette use confirmed in 215. Cases have occurred in 33 states and one territory. A total of 84% of the patients reported having used tetrahydrocannabinol (THC) products in e-cigarette devices.
A preliminary report on the situation by Jennifer Layden, MD, of the department of public health in Illinois and colleagues – including a preliminary case definition – was simultaneously released in the New England Journal of Medicine (2019 Sep 6. doi: 10.1056/NEJMoa1911614).
No single device or substance was common to all the cases, leading officials to issue a blanket warning against e-cigarettes, especially those containing THC.
“We believe a chemical exposure is likely related, but more information is needed to determine what substances. Some labs have identified vitamin E acetate in some samples,” said Dana Meaney-Delman, MD, MPH, incident manager, CDC 2019 Lung Injury Response. “Continued investigation is needed to identify the risk associated with a specific product or substance.”
Besides vitamin E acetate, federal labs are looking at other cannabinoids, cutting agents, diluting agents, pesticides, opioids, and toxins.
Officials also issued a general warning about the products. Youths, young people, and pregnant women should never use e-cigarettes, they cautioned, and no one should buy them from a noncertified source, a street vendor, or a social contact. Even cartridges originally obtained from a certified source should never have been altered in any way.
Dr. Layden and colleagues reported that bilateral lung infiltrates was characterized in 98% of the 53 patients hospitalized with the recently reported e-cigarette–induced lung injury. Nonspecific constitutional symptoms, including fever, chills, weight loss, and fatigue, were present in all of the patients.
Patients may show some symptoms days or even weeks before acute respiratory failure develops, and many had sought medical help before that. All presented with bilateral lung infiltrates, part of an evolving case definition. Many complained of nonspecific constitutional symptoms, including fever, chills, gastrointestinal symptoms, and weight loss. Of the patients who underwent bronchoscopy, many were diagnosed as having lipoid pneumonia, a rare condition characterized by lipid-laden macrophages.
“We don’t know the significance of the lipid-containing macrophages, and we don’t know if the lipids are endogenous or exogenous,” Dr. Meaney-Delman said.
The incidence of such cases appears to be rising rapidly, Dr. Layden noted. An epidemiologic review of cases in Illinois found that the mean monthly rate of visits related to severe respiratory illness in June-August was twice that observed during the same months last year.

No single device or substance was common to all the cases, leading officials to issue a blanket warning against e-cigarettes, especially those containing THC.
“We believe a chemical exposure is likely related, but more information is needed to determine what substances. Some labs have identified vitamin E acetate in some samples,” said Dana Meaney-Delman, MD, MPH, incident manager, CDC 2019 Lung Injury Response. “Continued investigation is needed to identify the risk associated with a specific product or substance.”
Besides vitamin E acetate, federal labs are looking at other cannabinoids, cutting agents, diluting agents, pesticides, opioids, and toxins.
Officials also issued a general warning about the products. Youths, young people, and pregnant women should never use e-cigarettes, they cautioned, and no one should buy them from a noncertified source, a street vendor, or a social contact. Even cartridges originally obtained from a certified source should never have been altered in any way.
Dr. Layden and colleagues reported that bilateral lung infiltrates was characterized in 98% of the 53 patients hospitalized with the recently reported e-cigarette–induced lung injury. Nonspecific constitutional symptoms, including fever, chills, weight loss, and fatigue, were present in all of the patients.
Patients may show some symptoms days or even weeks before acute respiratory failure develops, and many had sought medical help before that. All presented with bilateral lung infiltrates, part of an evolving case definition. Many complained of nonspecific constitutional symptoms, including fever, chills, gastrointestinal symptoms, and weight loss. Of the patients who underwent bronchoscopy, many were diagnosed as having lipoid pneumonia, a rare condition characterized by lipid-laden macrophages.
“We don’t know the significance of the lipid-containing macrophages, and we don’t know if the lipids are endogenous or exogenous,” Dr. Meaney-Delman said.
The incidence of such cases appears to be rising rapidly, Dr. Layden noted. An epidemiologic review of cases in Illinois found that the mean monthly rate of visits related to severe respiratory illness in June-August was twice that observed during the same months last year.
