ORLANDO – Dermatologists may have to contend with some of mankind’s oldest diseases – from group A streptococcus to measles – leading into 2020, Justin Finch, MD, said at the ODAC Dermatology, Aesthetic, & Surgical Conference.

While group A streptococcus has declined over the past century, there has been “an unprecedented” resurgence in severe, invasive group A streptococcal infections and severe epidemics of scarlet fever worldwide, including in industrialized regions like the United Kingdom. Shedding some light on why this may be occurring, Dr. Finch referred to a recently published population-based molecular epidemiologic study identified a new dominant emm1_UK lineage of Streptococcus pyogenes associated with such cases in England (Lancet Infect Dis. 2019 Nov;19(11):1209-18). This new lineage of S. pyogenes was genotypically distinct from other emm1 isolates and had greatly increased expression of the streptococcal pyrogenic exotoxin A, one of the exotoxins responsible for the clinical features of scarlet fever.

“We have not, to my knowledge, seen the strain yet in the United States,” said Dr. Finch, of Central Connecticut Dermatology in Cromwell. “Have it on your radar. With all of the worldwide travel patterns, I expect that you will see this in the United States at some point in the not-too-distant future.”

Also in 2019, promising data on the safety and effectiveness of the recombinant herpes zoster vaccine in immunocompromised patients became available for the first time. A randomized clinical trial published in JAMA of 1,846 patients who were immunosuppressed after autologous hematopoietic stem cell transplantation and received two doses of a recombinant zoster vaccine found that the patients had a reduced incidence of herpes zoster after a median follow-up of 21 months (JAMA. 2019 Jul 9;322[2]:123-33). The study found that the recombinant vaccine was both safe and effective in these immunocompromised patients, “so we can easily generalize this to our dermatology population as well,” Dr. Finch said. In comparing the live attenuated and recombinant vaccines, he noted the recombinant vaccine requires two doses but appears to be slightly more effective. “The number needed to treat to prevent [one case] of zoster is about half as high as that for the live vaccine, and most importantly for us is, it’s safe in immunocompromised patients.”

2019 also saw a record high in the number of measles cases in the United States, the highest since 1993, Dr. Finch pointed out. Most cases were seen in the area in and around New York City, but the percentage of people across the United States who are vaccinated against measles is below the threshold for herd immunity to protect immunocompromised patients. Measles requires a population vaccination rate of 94%, and less than half of U.S. counties in 2014 and 2015 reached that vaccination rate.

“Furthermore, if we look at that over the last 20 years, comparing the domestic measles cases to imported measles cases, we are increasingly breeding these measles epidemics right here at home, whereas they used to be imported from throughout the world,” said Dr. Finch. Patients with measles can be treated with vitamin A, he added, referring to a Cochrane review showing that 200,000 units of vitamin A given daily for 2 days decreased the mortality rate of measles by about 80%. Measles is on the Centers for Disease Control and Prevention’s list of reportable diseases, so should be reported to local health authorities, and will be followed up with confirmatory testing.

In 2019, a study examining herd protection of oral human papillomavirus infection in men and women compared the prevalence of oral HPV infection based on the 4 HPV types present in the quadrivalent HPV vaccine with 33 nonvaccine types from 2009 to 2016. There was no change in the prevalence of nonvaccine type oral HPV infections among men who were unvaccinated, but the prevalence of oral HPV infections because of the four strains in the quadrivalent HPV vaccine declined from 2.7% in 2009-2010 to 1.6% in 2015-2016 (JAMA. 2019 Sep 10;322[10]:977-9). Among unvaccinated women, the prevalence of nonvaccine- and vaccine-type oral HPV infections did not change between the two time periods.

“Notably, this only occurred in men,” Dr. Finch said. Herd immunity is being achieved in men “because we’re vaccinating all women, [but] we’re not seeing that herd immunity in women. Which begs the question: Why are we still vaccinating only half of our population?”

One study published in 2019 (Br J Dermatol. 2019 Nov;181[5]:1093-5) described a patient with CARD9 mutations, which predispose individuals to deep invasive infections – a disseminated Microsporum infection in this case, Dr. Finch said. “You shouldn’t see that,” he added, noting that these mutations are known to predispose individuals to severe Trichophyton infections and familial candidiasis.

“What I think is interesting about this is that, as we look forward to 2020, we’re going to increasingly see studies like this that are identifying specific mutations in our community that underlie a lot of these weird infections,” he added. “I wouldn’t be surprised if within the span of our careers, we find that a lot of those severe treatment-refractory reports that so commonly plague your everyday clinic have some underlying, specific immunity.”

Dr. Finch reported no relevant conflicts of interest.

LONDON – Treatment with the antihypertensive drug losartan raised no safety concerns in the treatment of children with epidermolysis bullosa (EB) and reduced signs of fibrosis in an early clinical study.

In the ongoing phase 1/2 REFLECT (Recessive dystrophic EB: Mechanisms of fibrosis and its prevention with Losartan in vivo) trial, involving 29 children, no severe complications have been noted so far, according to one of the study investigators, Dimitra Kiritsi, MD, of the University of Freiburg, Germany. At the EB World Congress, organized by the Dystrophic Epidermolysis Bullosa Association (DEBRA), she presented interim data on 18 patients in the trial, emphasizing that the primary aim of the trial was to evaluate the safety of this treatment approach.

Over the 2 years the trial has been underway, 65 adverse events have been reported, of which 4 have been severe. Two of these were bacterial infections that required hospital treatment and the other two were a reduction in the general health condition of the child.

Losartan is an angiotensin-II receptor blocker (ARB) that has been in clinical use for more than 25 years in adults and 15 years in children over the age of 6 years.

The drug may be used for treating recessive dystrophic EB (RDEB) in the future, Dr. Kiritsi said, because it attenuates tumor necrosis factor–beta (TGF-beta) signaling, which is thought to be involved in the fibrotic process. So while it may not target the genetic defect, it could help ameliorate the effects of the disease.

The precursor to REFLECT was a study performed in a mouse disease model of EB (EMBO Mol Med. 2015;7:1211-28) where a reduction in fibrotic scarring was seen with losartan with “remarkable effects” on “mitten” deformity, Dr. Kiritsi said. The results of that study suggested that the earlier treatment with losartan was started in the course of the disease, the better the effect, she added. (Mitten deformity is the result of fused skin between the fingers or toes, and the subsequent buildup of fibrotic tissue causes the hand or foot to contract.)

REFLECT is an investigator-initiated trial that started in 2017 and is being funded by DEBRA International. It is a dual-center, nonrandomized, single-arm study in which children aged 3-16 years with RDEB are treated with losartan for 10 months, with follow-up at 3 months.

Various secondary endpoints were included to look for the first signs of any efficacy: the Physician’s Global Assessment (PGA), the Birmingham Epidermolysis Bullosa Severity Score (BEBS), the Epidermolysis Bullosa Disease Activity and Scarring Index (EBDASI), the Itch Assessment Scale for the Pediatric Burn Patients, and two quality of life indices: the Quality of Life in EB (QOLEB) questionnaire and the Children’s Dermatology Life Quality Index (CDLQI).

Dr. Kiritsi highlighted a few of the secondary endpoint findings, saying that reduced BEBS scores showed there was “amelioration of the patients’ phenotype” and that EBDASI scores also decreased, with “nearly 60% of the patients having significant improvement of their skin disease.” Importantly, itch improved in most of the patients, she said. Reductions in CDLQI were observed, “meaning that quality of life was significantly better at the end of the trial.” There were also decreases in inflammatory markers, such as C-reactive protein, interleukin-6, and TNF-alpha.

Although there is no validated tool available to assess hand function, Dr. Kiritsi and her team used their own morphometric scoring instrument to measure how far the hand could stretch; their evaluations suggested that this measure improved – or at least did not worsen – with losartan treatment, she noted.

A larger, randomized trial is needed to confirm if there is any benefit of losartan, but first, a new, easy-to-swallow losartan formulation needs to be developed specifically for EB in the pediatric population, Dr. Kiritsi said. Although a pediatric suspension of losartan was previously available, it is no longer on the market, so the next step is to develop a formulation that could be used in a pivotal clinical trial, she noted.

“Losartan faces fewer technical hurdles compared to other novel treatments as it is an established medicine,” Dr. Kiritsi and associates observed in a poster presentation. There are still economic hurdles, however, since “with losartan patents expired, companies cannot expect to recoup an investment into clinical studies” and alternative funding sources are needed.

In 2019, losartan was granted an orphan drug designation for the treatment of EB from both the Food and Drug Administration and the European Medicines Agency, but its use remains off label in children. “We decided to treat children,” Dr. Kiritsi said, “because we wanted to start as early as possible. If you already have mitten deformities, these cannot be reversed.”

DEBRA International funded the study. Dr. Kiritsi received research support from Rheacell GmbH and honoraria or consultation fees from Amryt Pharma and Rheacell GmbH. She has received other support from DEBRA International, EB Research Partnership, Fritz Thyssen Stiftung, German Research Foundation (funding of research projects), and 3R Pharma Consulting and Midas Pharma GmbH (consultation for losartan new drug formulation).

A new line of Barbie dolls unveiled by Mattel earlier this month includes one with vitiligo, much to the delight of clinicians who treat children and adolescents with the condition.

Mattel, Inc.

“When I see young children and adolescents with vitiligo, it is very common for me to feel their emotional suffering from their skin condition,” Seemal R. Desai, MD, a dermatologist at the University of Texas Southwestern Medical Center in Dallas said in an interview. “Kids can be cruel. Name calling, social ostracizing, [and] effects on self-esteem are all things I have seen amongst my patients and their families in their own struggles with vitiligo.”

According to a brand communications representative from toymaker Mattel, which began manufacturing Barbie dolls in 1959, the company worked with a board-certified dermatologist to include a doll with vitiligo in its 2020 “Fashionistas” line. “As we continue to redefine what it means to be a ‘Barbie’ or look like Barbie, offering a doll with vitiligo in our main doll line allows kids to play out even more stories they see in the world around them,” the representative wrote in an email message. Other dolls debuting as part of the lineup include one with no hair, one with a darker skin tone that uses a gold prosthetic limb, and a Ken doll with long rooted hair (think Jeff Spicoli in “Fast Times at Ridgemont High,” but about six inches longer).

Such efforts to celebrate diversity and inclusiveness go far in helping children and young adults to embrace their skin and their own identities, said Dr. Desai, the immediate past president of the Skin of Color Society and a member of the American Academy of Dermatology board of directors. “One nuance, perhaps even more important, is that the Barbie can help to break down barriers, create awareness, and potentially even reduce bullying, stigma, and lack of knowledge about vitiligo amongst the general public who don’t understand vitiligo,” he said. “I hope the public and social media will embrace this new Barbie. Who knows? Pretty soon, vitiligo may no longer be a ‘thing’ that causes ‘stares’ and ‘glares.’ ”

Referring to the Barbie with no hair in the new line of dolls, the Mattel statement said, “ if a girl is experiencing hair loss for any reason, she can see herself reflected in the line.”

Mattel, Inc.

In 2019, Mattel introduced a lineup of Barbie dolls reflecting permanent disabilities, including one with a prosthetic limb. For that effort, the company collaborated with then-12-year-old Jordan Reeves, the “Born Just Right” coauthor “who is on a mission to build creative solutions that help kids with disabilities, to create a play experience that is as representative as possible,” the Mattel representative wrote.

Name calling, social ostracizing, [and] effects on self-esteem are all things I have seen amongst my patients and their families in their own struggles with vitiligo.”

According to a brand communications representative from toymaker Mattel, which began manufacturing Barbie dolls in 1959, the company worked with a board-certified dermatologist to include a doll with vitiligo in its 2020 “Fashionistas” line. “As we continue to redefine what it means to be a ‘Barbie’ or look like Barbie, offering a doll with vitiligo in our main doll line allows kids to play out even more stories they see in the world around them,” the representative wrote in an email message. Other dolls debuting as part of the lineup include one with no hair, one with a darker skin tone that uses a gold prosthetic limb, and a Ken doll with long rooted hair (think Jeff Spicoli in “Fast Times at Ridgemont High,” but about six inches longer).

Such efforts to celebrate diversity and inclusiveness go far in helping children and young adults to embrace their skin and their own identities, said Dr. Desai, the immediate past president of the Skin of Color Society and a member of the American Academy of Dermatology board of directors. “One nuance, perhaps even more important, is that the Barbie can help to break down barriers, create awareness, and potentially even reduce bullying, stigma, and lack of knowledge about vitiligo amongst the general public who don’t understand vitiligo,” he said. “I hope the public and social media will embrace this new Barbie. Who knows? Pretty soon, vitiligo may no longer be a ‘thing’ that causes ‘stares’ and ‘glares.’ ”

Referring to the Barbie with no hair in the new line of dolls, the Mattel statement said, “ if a girl is experiencing hair loss for any reason, she can see herself reflected in the line.”

In 2019, Mattel introduced a lineup of Barbie dolls reflecting permanent disabilities, including one with a prosthetic limb. For that effort, the company collaborated with then-12-year-old Jordan Reeves, the “Born Just Right” coauthor “who is on a mission to build creative solutions that help kids with disabilities, to create a play experience that is as representative as possible,” the Mattel representative wrote.

LONDON – More than £2.8 million (almost $3.7 million) was spent every year on wound dressings and bandages for treatment in a group of 60 people with recessive dystrophic epidermolysis bullosa (RDEB), according to a report at the EB World Congress, organized by the Dystrophic Epidermolysis Bullosa Association (DEBRA).

Results from the Prospective Epidermolysis Bullosa Longitudinal Evaluation Study (PEBLES), which is looking at the natural history of RDEB, showed that wound dressing and bandage costs were highest for study participants with the generalized severe (RDEB-GS) subtype, at just over £85,156 (about $112,450) per patient annually. Respective yearly costs for the generalized intermediate (RDEB-GI) and inversa (RDEB-INV) subtypes were £10,112 (about $13,350) and £1,699 (about $2,240) per patient.

Looking at the costs associated with EB is important, said one of the lead investigators for PEBLES, Jemima Mellerio, MD, FRCP, consultant dermatologist at St John’s Institute of Dermatology, at Guy’s & St. Thomas’ NHS Foundation Trust, London.

“If we are going to justify the kind of expenditure [associated with new treatments], we need to know that what we are treating is already a significant burden on our health care systems,” Dr. Mellerio said.

PEBLES is an ongoing London-based registry study that is enrolling patients with all subtypes of RDEB. Data are collected via a tablet device and include demographic data, information on clinical features, results of skin biopsies and genetic tests, and laboratory findings, as well as objective disease severity and subjective patient-orientated outcome scores.

So far, 60 patients – 49 adults and 11 children – have been enrolled in PEBLES since November 2014: 26 with RDEB-GS, 23 with RDEB-GI, 9 with RDEB-INV, and 2 with the pruriginosa RDEB subtype (RDEB-PR).

Most of the participants (71%) changed all their wound dressings at one time, patching up when required. Fourteen of 49 participants had paid people to help them change their dressings and when the total cost of combined wound dressings and paid care was taken into consideration, the mean annual cost per patient was around £2,500 (about $3,300) for RDEB-INV, £10,375 (about $13,700) per patient for RDEB-GS, and a staggering £98,000 (about $129,000) per patient for RDEB-GS. The total annual cost of dressings and associated care was an estimated £3,184,229 (about $4.2 million).

In addition to data on the cost of wound dressings, data on itch and pain and quality of life were presented at the EB World Congress and discussed by Dr. Mellerio.

A total of 42 participants older than 8 years of age had itch measured via the Leuven Itch Scale, she reported, noting that itch was a consistent symptom across all subtypes of RDEB. Itch is important as it not only causes problems with skin lesions and healing, but also significantly affects sleep and has a negative impact on patients’ mood, she emphasized.

A small survey suggests many patients consult social media for advice on acne treatment and follow recommendations that don’t align with clinical guidelines.

llhedgehogll/Thinkstock

Of the 130 patients surveyed, 45% consulted social media for advice on acne treatment, and 52% of those patients followed recommendations that don’t correspond to American Academy of Dermatology (AAD) guidelines. Most patients reported no improvement (40%) or minimal improvement (53%) in their acne after following advice from social media.

“These results suggest that dermatologists should inquire about social media acne treatment advice and directly address misinformation,” wrote Ahmed Yousaf, of West Virginia University, Morgantown, W.Va., and colleagues. Their report is in Pediatric Dermatology.

They conducted the survey of 130 patients treated for acne at West Virginia University. Most patients were female (60%), and a majority were adolescents (54%) or adults (44%). About half of the patients (51%) said their acne was moderate, 38% said it was severe, and 11% said it was mild.

Most patients said they consulted a medical professional for their first acne treatment (58%). However, 16% of patients said they first went to social media for advice, 26% said they consulted family or friends, and 10% took “other” steps as their first approach to acne treatment.

In all, 45% of patients consulted social media for acne treatment advice at some point. This includes 54% of women, 31% of men, 41% of adolescents, and 51% of adults. Social media consultation was more common among patients with severe acne (54%) than among those with mild (36%) or moderate (39%) acne.

The most common social media platforms used were YouTube and Instagram (58% each), followed by Pinterest (31%), Facebook (19%), Twitter (9%), Snapchat (7%), and Tumblr (3%). (Patients could select more than one social media platform.)

Roughly half (52%) of patients who consulted social media followed advice that does not align with AAD guidelines, 31% made changes that are recommended by the AAD, and 17% did not provide information on recommendations they followed.

The social media advice patients followed included using over-the-counter products (81%), making dietary changes (40%), using self-made products (19%), taking supplements (16%), and making changes in exercise routines (7%). (Patients could select more than one treatment approach.)

Among the patients who followed social media advice, 40% said they saw no change in their acne, and 53% reported minimal improvement.

“Only 7% of social media users reported significant improvement in their acne,” Mr. Yousaf and colleagues wrote. “This may be due to less accurate content found on social media compared to other health care sources.”

The authors acknowledged that the patients surveyed were recruited from a dermatology clinic. Therefore, these results “likely underestimate the percentage of patients who improve from social media acne treatment advice and do not consult a medical professional.”

Mr. Yousaf and colleagues did not disclose any conflicts of interest.

Most patients with epidermolysis bullosa who use topical products choose antimicrobials, according to data from a survey of 202 children and adults.

Management of epidermolysis bullosa (EB) involves a combination of skin protection and infection management, but patient home care practices have not been well studied, wrote Leila Shayegan of Columbia University, New York, and colleagues.

In a study published in Pediatric Dermatology, the researchers surveyed 202 patients who were enrolled in the Epidermolysis Bullosa Clinical Characterization and Outcomes Database during 2017. The patients ranged in age from 1 month to 62 years with an average age of 11 years; 52% were female. The patients represented a range of EB subtypes, including 130 patients with dystrophic EB, 51 patients with EB simplex, 21 with junctional EB, and 3 patients each with Kindler syndrome and unspecified subtypes.

Overall, most of the patients reported cleaning their skin either every day (37%) or every other day (32%). Of the 188 patients who reported using topical products on their wounds, 131 (70%) said they used at least one antimicrobial product, while 125 patients (66%) reported using at least one emollient; 32 (17%) used emollients only, and 21(11%) reported no use of topical products.

The most popular topical antibiotics were mupirocin (31%) and bacitracin (31%). In addition, 14% of respondents used silver-containing products, and 16% used medical-grade honey. Roughly half (51%) of patients who reported use of at least one antimicrobial product used two or more different antimicrobial products.

A total of 38% of patients used only water for cleansing. Of the 131 patients who reported using additives in their cleansing water, 57% added salt, 54% added bleach, 27% added vinegar, and 26% reported “other” additive use, which could include Epsom salt, baking soda, oatmeal, or essential oils, the researchers said. The concentrations of these additives ranged from barely effective 0.002% sodium hypochlorite and 0.002% acetic acid solutions to potentially cytotoxic solutions of 0.09% sodium hypochlorite and 0.156% acetic acid.

“Although the survey was not designed to correlate skin care practices with wound culture results and resistance patterns, widespread use of topical antimicrobials described among EB patients highlights the need for increased emphasis on antibiotic stewardship,” the researchers noted. They added that health care providers should educate patients and families not only about mindful use of antibiotics, but also appropriate concentrations of cleansing additives.

“Optimizing EB patient home skin care routines, along with future longitudinal studies on the impact of EB skin care interventions on microbial resistance patterns, wound healing and [squamous cell carcinoma] risk are necessary to improve outcomes for patients with EB,” they emphasized.

The Epidermolysis Bullosa Clinical Characterization and Outcomes Database used in the study is funded by the Epidermolysis Bullosa Research Partnership and the Epidermolysis Bullosa Medical Research Foundation. Ms. Shayegan had no financial conflicts to disclose. Several coauthors disclosed relationships with multiple companies including Abeona Therapeutics, Castle Creek Pharmaceuticals, Fibrocell Science, ProQR, and Scioderm.

ORLANDO – Because Food and Drug Administration–approved treatment options for children and adolescents with severe dermatologic diseases are limited, systemic therapies for these patients often require the use of off-label medications. However, this scenario is changing, A. Yasmine Kirkorian, MD, said at the ODAC Dermatology, Aesthetic & Surgical Conference.

“I really would like to emphasize that children with severe disease need to be treated,” added Dr. Kirkorian, a pediatric dermatologist at George Washington University, Washington, and Children’s National Health System, where she is interim chief of the division of dermatology.

Current on-label systemic therapies for pediatric skin disease include etanercept for psoriasis (4 years and older), ustekinumab for psoriasis (12 years and older), adalimumab for hidradenitis suppurativa (12 years and older), and omalizumab for chronic idiopathic urticaria (12 years and older). A new addition to the list is dupilumab, which was approved for children and adolescents with atopic dermatitis (AD) aged 12 years and older in 2019, she noted.

Dupilumab is currently being studied in children aged 6 months to 12 years, and other clinical trials are evaluating more options for pediatric patients with AD, alopecia areata, and psoriasis. They include a clinical trial of the oral Janus kinase 3 (JAK3) inhibitor PF-06651600 in patients aged 12 years and older with alopecia areata. Six biologic therapies are being evaluated for psoriasis in patients beginning at 6 years: ixekizumab, secukinumab, ustekinumab, guselkumab, brodalumab, and apremilast.

Some systemic therapies are off-label “but used all the time” for dermatologic diseases in pediatrics, Dr. Kirkorian noted. One example is methotrexate, which is approved by the FDA for acute lymphoblastic leukemia, meningeal leukemia, and juvenile idiopathic arthritis down to infancy. Having existing efficacy and safety data for a medication in a pediatric population, even for a different disease, can be helpful when counseling parents of children with severe dermatologic disease. “If you have something, even in an older population of children, it can be reassuring, or you can use evidence from other diseases,” she said.

While methotrexate is a cheap option and approved by the FDA for other pediatric indications down to infancy, the cons of using it to treat AD in pediatric patients are numerous. Treatment requires a number of blood draws for lab testing, which can be discouraging for younger patients, and the reported adverse effect profile may be concerning to some parents, while “in practice doesn’t really occur,” she said. Methotrexate is a teratogen so is not appropriate for teenagers who are sexually active and not using contraception.

The “biggest problem,” though, is the issue of whether methotrexate is effective, since it doesn’t always work for AD, Dr. Kirkorian said. “Even at the highest doses, I often feel that we fail the atopic children,” as opposed to using it to treat psoriasis, “where you know I’m going to get you on something that works.”

In contrast, cyclosporine is FDA approved down to infancy, and works quickly as a bridge to other therapy, and is not expensive, Dr. Kirkorian said. Cons include the need for blood draws, blood pressure checks, drug interactions, and adverse effects, she noted, adding that she tries to use cyclosporine as a bridge to on-label and off-label dupilumab.

Even with FDA approval for dupilumab down to age 12 years, she said it can be difficult to get insurance approval for the on-label treatment for patients in this age group with AD, before they first fail other therapies (even with off-label systemic drugs). For patients under age 12 years, getting approval is even more challenging and requires rigorous documentation of what therapies the child has failed, and how it has affected their quality of life, she said.

“If you send in a letter to the insurance company without an IGA [Investigator Global Assessment] or SCORAD, you’re going to get rejected,” Dr. Kirkorian said. In addition to those two measures, she provides “everything else,” including the impact of the disease on quality of life of patients, and school, she said, adding, “Did they miss school, did they get hospitalized for infections? And do they have comorbid diseases that might help you get approval?”

In pediatric patients with psoriasis, common issues are more likely to be about how insurance dictates step therapy. She has often found that young children may stop responding to etanercept after a few years, which can justify a switch to ustekinumab or a new treatment in a clinical trial, she said. Adolescents with psoriasis can receive ustekinumab, which is approved for psoriasis in patients aged 12-17 years, she said, noting that the infrequent ustekinumab dosing schedule is often beneficial in this population.

When all other approved options fail for young patients with psoriasis, justifying off-label use isn’t always easy. “You just have to make a justification based on the literature, even though it’s off label,” citing available safety information for other diseases, and “demonstrate over and over the impact on quality of life,” which works “most of the time,” Dr. Kirkorian said.

She reported having no conflicts of interest.

A biopsy of the skin was consistent with folliculitis, but a dental panoramic x-ray revealed an abscess of tooth number 30, which is on the right side. This combination of findings was consistent with a dental sinus.

This unusual diagnosis is most common in adults and arises from dental disease in the mid mandibular pre-molars. It will appear as an abscess or crusted papule and can occur in the lower jaw, neck, or occasionally, the mid cheek. Children are rarely affected. Because the sinus opening relieves pressure from the dental abscess, there is often little to no pain.

It can be challenging to convince a patient that his or her skin lesion derives from dental disease. Often, though, patients are glad it is not cancer. Patients should be referred to an endodontist for a work-up and a root canal, which is the preferred treatment. If a root canal is not feasible, dental extraction will lead to cure.

In this case, the patient promptly underwent a root canal and was cured in 2 weeks. The scar from the papule can have a depressed appearance (FIGURE 2), which can be addressed with excisional scar revision once the underlying abscess is cured.

Imagine a patient suffering with horrible psoriasis for decades having failed “every available treatment.” Imagine him living all that time with “flaking, cracking, painful, itchy skin,” only to develop cirrhosis after exposure to toxic therapies.

Then imagine the experience for that patient when, 2 weeks after initiating treatment with a new interleukin-17 inhibitor, his skin clears completely.

“Two weeks later it’s all gone – it was a moment to behold,” said Joel M. Gelfand, MD, professor of dermatology and epidemiology at the University of Pennsylvania, Philadelphia, who had cared for the man for many years before a psoriasis treatment revolution of sorts took the field of dermatology by storm.

“The progress has been breathtaking – there’s no other way to describe it – and it feels like a miracle every time I see a new patient who has tough disease and I have all these things to offer them,” he continued. “For most patients, I can really help them and make a major difference in their life.”

Much of the progress in psoriasis treatment in the past 50 years unfolded over the past 2 decades, with biologics emerging for psoriasis, said Mark Lebwohl, MD, Waldman professor of dermatology and chair of the Kimberly and Eric J. Waldman department of dermatology at the Icahn School of Medicine at Mount Sinai, New York.

Dr. Lebwohl recounted some of his own experiences with psoriasis patients before the advent of treatments – particularly biologics – that have transformed practice.

There was a time when psoriasis patients had little more to turn to than the effective – but “disgusting” – Goeckerman Regimen involving cycles of UVB light exposure and topical crude coal tar application. Initially, the regimen, which was introduced in the 1920s, was used around the clock on an inpatient basis until the skin cleared, Dr. Lebwohl said.

In the 1970s, the immunosuppressive chemotherapy drug methotrexate became the first oral systemic therapy approved for severe psoriasis. For those with disabling disease, it offered some hope for relief, but only about 40% of patients achieved at least a 75% reduction in the Psoriasis Area and Severity Index score (PASI 75), he said, adding that they did so at the expense of the liver and bone marrow. “But it was the only thing we had for severe psoriasis other than light treatments.”

In the 1980s and 1990s, oral retinoids emerged as a treatment for psoriasis, and the immunosuppressive drug cyclosporine used to prevent organ rejection in some transplant patients was found to clear psoriasis in affected transplant recipients. Although they brought relief to some patients with severe, disabling disease, these also came with a high price. “It’s not that effective, and it has lots of side effects ... and causes kidney damage in essentially 100% of patients,” Dr. Lebwohl said of cyclosporine.

“So we had treatments that worked, but because the side effects were sufficiently severe, a lot of patients were not treated,” he said.

Enter the biologics era

The early 2000s brought the first two approvals for psoriasis: alefacept (Amevive), a “modestly effective, but quite safe” immunosuppressive dimeric fusion protein approved in early 2003 for moderate to severe plaque psoriasis, and efalizumab (Raptiva), a recombinant humanized monoclonal antibody approved in October 2003; both were T-cell–targeted therapies. The former was withdrawn from the market voluntarily as newer agents became available, and the latter was withdrawn in 2009 because of a link with development of progressive multifocal leukoencephalopathy.

Tumor necrosis factor (TNF) blockers, which had been used effectively for RA and Crohn’s disease, emerged next, and were highly effective, much safer than the systemic treatments, and gained “very widespread use,” Dr. Lebwohl said.

Alan Menter, MD, chairman of the division of dermatology at Baylor University Medical Center, Dallas, also a prolific researcher – and chair of the guidelines committee that published two new sets of guidelines for psoriasis treatment in 2019 – said that the field of dermatology was “late to the biologic evolution,” as many of the early biologics were first approved for PsA.

“But over the last 10 years, things have changed dramatically,” he said. “After that we suddenly leapt ahead of everybody. ... We now have 11 biologic drugs approved for psoriasis, which is more than any other disease has available.”

It’s been “highly exciting” to see this “evolution and revolution,” he commented, adding that one of the next challenges is to address the comorbidities, such as cardiovascular disease, associated with psoriasis.

“The big question now ... is if you improve skin and you improve joints, can you potentially reduce the risk of coronary artery disease,” he said. “Everybody is looking at that, and to me it’s one of the most exciting things that we’re doing.”

Work is ongoing to look at whether the IL-17s and IL-23s have “other indications outside of the skin and joints,” both within and outside of dermatology.

Like Dr. Gottlieb, Dr. Menter also mentioned the potential for hidradenitis suppurativa, and also for a condition that is rarely discussed or studied: genital psoriasis. Ixekizumab has recently been shown to work in about 75% of patients with genital psoriasis, he noted.

Another important area of research is the identification of biomarkers for predicting response and relapse, he said. For now, biomarker research has disappointed, he added, predicting that it will take at least 3-5 years before biomarkers to help guide treatment are identified.

Indeed, Dr. Gelfand, who also is director of the Psoriasis and Phototherapy Treatment Center, vice chair of clinical research, and medical director of the dermatology clinical studies unit at the University of Pennsylvania, agreed there is a need for research to improve treatment selection.

Advances are being made in genetics – with more than 80 different genes now identified as being related to psoriasis – and in medical informatics – which allow thousands of patients to be followed for years, he said, noting that this could elucidate immunopathological features that can improve treatments, predict and prevent comorbidity, and further improve outcomes.

“We also need care that is more patient centered,” he said, describing the ongoing pragmatic LITE trial of home- or office-based phototherapy for which he is the lead investigator, and other studies that he hopes will expand access to care.

Kenneth Brian Gordon, MD, chair and professor of dermatology at the Medical College of Wisconsin, Milwaukee, whose career started in the basic science immunology arena, added the need for expanding benefit to patients with more-moderate disease. Like Dr. Menter, he identified psoriasis as the area in medicine that has had the greatest degree of advancement, except perhaps for hepatitis C.

He described the process not as a “bench-to-bedside” story, but as a bedside-to-bench, then “back-to-bedside” story.

It was really about taking those early T-cell–targeted biologics and anti-TNF agents from bedside to bench with the realization of the importance of the IL-23 and IL-17 pathways, and that understanding led back to the bedside with the development of the newest agents – and to a “huge difference in patient’s lives.”

“But we’ve gotten so good at treating patients with severe disease ... the question now is how to take care of those with more-moderate disease,” he said, noting that a focus on cost and better delivery systems will be needed for that population.

That research is underway, and the future looks bright – and clear.
 

“I think with psoriasis therapy and where we’ve come in the last 20 years ... we have a hard time remembering what it was like before we had biologic agents” he said. “Our perspective has changed a lot, and sometimes we forget that.”

In fact, “psoriasis has sort of dragged dermatology into the world of modern clinical trial science, and we can now apply that to all sorts of other diseases,” he said. “The psoriasis trials were the first really well-done large-scale trials in dermatology, and I think that has given dermatology a real leg up in how we do clinical research and how we do evidence-based medicine.”

All of the doctors interviewed for this story have received funds and/or honoraria from, consulted with, are employed with, or served on the advisory boards of manufacturers of biologics. Dr. Gelfand is a copatent holder of resiquimod for treatment of cutaneous T-cell lymphoma and is deputy editor of the Journal of Investigative Dermatology.

It was really about taking those early T-cell–targeted biologics and anti-TNF agents from bedside to bench with the realization of the importance of the IL-23 and IL-17 pathways, and that understanding led back to the bedside with the development of the newest agents – and to a “huge difference in patient’s lives.”

“But we’ve gotten so good at treating patients with severe disease ... the question now is how to take care of those with more-moderate disease,” he said, noting that a focus on cost and better delivery systems will be needed for that population.

That research is underway, and the future looks bright – and clear.
 

“I think with psoriasis therapy and where we’ve come in the last 20 years ... we have a hard time remembering what it was like before we had biologic agents” he said. “Our perspective has changed a lot, and sometimes we forget that.”

In fact, “psoriasis has sort of dragged dermatology into the world of modern clinical trial science, and we can now apply that to all sorts of other diseases,” he said. “The psoriasis trials were the first really well-done large-scale trials in dermatology, and I think that has given dermatology a real leg up in how we do clinical research and how we do evidence-based medicine.”

All of the doctors interviewed for this story have received funds and/or honoraria from, consulted with, are employed with, or served on the advisory boards of manufacturers of biologics.

Imagine a patient suffering with horrible psoriasis for decades having failed “every available treatment.” Imagine him living all that time with “flaking, cracking, painful, itchy skin,” only to develop cirrhosis after exposure to toxic therapies.

Then imagine the experience for that patient when, 2 weeks after initiating treatment with a new interleukin-17 inhibitor, his skin clears completely.

“Two weeks later it’s all gone – it was a moment to behold,” said Joel M. Gelfand, MD, professor of dermatology and epidemiology at the University of Pennsylvania, Philadelphia, who had cared for the man for many years before a psoriasis treatment revolution of sorts took the field of dermatology by storm.

“The progress has been breathtaking – there’s no other way to describe it – and it feels like a miracle every time I see a new patient who has tough disease and I have all these things to offer them,” he continued. “For most patients, I can really help them and make a major difference in their life.”

Much of the progress in psoriasis treatment in the past 50 years unfolded over the past 2 decades, with biologics emerging for psoriasis, said Mark Lebwohl, MD, Waldman professor of dermatology and chair of the Kimberly and Eric J. Waldman department of dermatology at the Icahn School of Medicine at Mount Sinai, New York.

Dr. Lebwohl recounted some of his own experiences with psoriasis patients before the advent of treatments – particularly biologics – that have transformed practice.

There was a time when psoriasis patients had little more to turn to than the effective – but “disgusting” – Goeckerman Regimen involving cycles of UVB light exposure and topical crude coal tar application. Initially, the regimen, which was introduced in the 1920s, was used around the clock on an inpatient basis until the skin cleared, Dr. Lebwohl said.

In the 1970s, the immunosuppressive chemotherapy drug methotrexate became the first oral systemic therapy approved for severe psoriasis. For those with disabling disease, it offered some hope for relief, but only about 40% of patients achieved at least a 75% reduction in the Psoriasis Area and Severity Index score (PASI 75), he said, adding that they did so at the expense of the liver and bone marrow. “But it was the only thing we had for severe psoriasis other than light treatments.”

In the 1980s and 1990s, oral retinoids emerged as a treatment for psoriasis, and the immunosuppressive drug cyclosporine used to prevent organ rejection in some transplant patients was found to clear psoriasis in affected transplant recipients. Although they brought relief to some patients with severe, disabling disease, these also came with a high price. “It’s not that effective, and it has lots of side effects ... and causes kidney damage in essentially 100% of patients,” Dr. Lebwohl said of cyclosporine.

“So we had treatments that worked, but because the side effects were sufficiently severe, a lot of patients were not treated,” he said.

Enter the biologics era

The early 2000s brought the first two approvals for psoriasis: alefacept (Amevive), a “modestly effective, but quite safe” immunosuppressive dimeric fusion protein approved in early 2003 for moderate to severe plaque psoriasis, and efalizumab (Raptiva), a recombinant humanized monoclonal antibody approved in October 2003; both were T-cell–targeted therapies. The former was withdrawn from the market voluntarily as newer agents became available, and the latter was withdrawn in 2009 because of a link with development of progressive multifocal leukoencephalopathy.

Tumor necrosis factor (TNF) blockers, which had been used effectively for RA and Crohn’s disease, emerged next, and were highly effective, much safer than the systemic treatments, and gained “very widespread use,” Dr. Lebwohl said.

Alan Menter, MD, chairman of the division of dermatology at Baylor University Medical Center, Dallas, also a prolific researcher – and chair of the guidelines committee that published two new sets of guidelines for psoriasis treatment in 2019 – said that the field of dermatology was “late to the biologic evolution,” as many of the early biologics were first approved for PsA.

“But over the last 10 years, things have changed dramatically,” he said. “After that we suddenly leapt ahead of everybody. ... We now have 11 biologic drugs approved for psoriasis, which is more than any other disease has available.”

It’s been “highly exciting” to see this “evolution and revolution,” he commented, adding that one of the next challenges is to address the comorbidities, such as cardiovascular disease, associated with psoriasis.

“The big question now ... is if you improve skin and you improve joints, can you potentially reduce the risk of coronary artery disease,” he said. “Everybody is looking at that, and to me it’s one of the most exciting things that we’re doing.”

Work is ongoing to look at whether the IL-17s and IL-23s have “other indications outside of the skin and joints,” both within and outside of dermatology.

Like Dr. Gottlieb, Dr. Menter also mentioned the potential for hidradenitis suppurativa, and also for a condition that is rarely discussed or studied: genital psoriasis. Ixekizumab has recently been shown to work in about 75% of patients with genital psoriasis, he noted.

Another important area of research is the identification of biomarkers for predicting response and relapse, he said. For now, biomarker research has disappointed, he added, predicting that it will take at least 3-5 years before biomarkers to help guide treatment are identified.

Indeed, Dr. Gelfand, who also is director of the Psoriasis and Phototherapy Treatment Center, vice chair of clinical research, and medical director of the dermatology clinical studies unit at the University of Pennsylvania, agreed there is a need for research to improve treatment selection.

Advances are being made in genetics – with more than 80 different genes now identified as being related to psoriasis – and in medical informatics – which allow thousands of patients to be followed for years, he said, noting that this could elucidate immunopathological features that can improve treatments, predict and prevent comorbidity, and further improve outcomes.

“We also need care that is more patient centered,” he said, describing the ongoing pragmatic LITE trial of home- or office-based phototherapy for which he is the lead investigator, and other studies that he hopes will expand access to care.

Kenneth Brian Gordon, MD, chair and professor of dermatology at the Medical College of Wisconsin, Milwaukee, whose career started in the basic science immunology arena, added the need for expanding benefit to patients with more-moderate disease. Like Dr. Menter, he identified psoriasis as the area in medicine that has had the greatest degree of advancement, except perhaps for hepatitis C.

He described the process not as a “bench-to-bedside” story, but as a bedside-to-bench, then “back-to-bedside” story.

ATLANTA – Psoriasis type and patient age at presentation among patients with psoriatic arthritis predict the timing of arthritis symptom synchronicity, according to findings from the Psoriatic Arthritis Registry of Turkey International Database.

Sharon Worcester/MDedge News

However, in those who develop arthritis symptoms first, age at onset is not predictive of psoriatic arthritis (PsA) symptom synchronicity, Umut Kalyoncu, MD, reported at the annual meeting of the American College of Rheumatology.

Of 1,631 patients from the registry, 1,251 had psoriasis first, 71 had arthritis first, and 309 had synchronous onset, which was defined as the onset of both psoriasis and arthritis symptoms within a 12-month period. The time from skin disease to PsA was 155.6 months, –67.4 months, and 1.8 months, among the groups, respectively, and the mean age at PsA onset was similar, ranging from about 41 to 42 years in those who developed arthritis first, said Dr. Kalyoncu, of the department of rheumatology at Hacettepe University, Ankara, Turkey.

However, the mean age of PsA onset among those who developed psoriasis first was 29.4 years, compared with 46.3 years in those who developed arthritis first.

“So there is a really big difference between psoriasis beginning age,” he said.

PsA types also differed by onset symptoms: Axial involvement was more common with arthritis-first onset at 38.0%, compared with 28.8% for psoriasis first and 27.8% for synchronous onset). Oligoarthritis occurred more often with arthritis-first onset (45.1% vs. 30.7% and 29.4%, respectively), and polyarthritis occurred less often with arthritis-first onset (33.8% vs. 49.4% and 47.6%, respectively), he said.

Psoriasis type also differed among the groups: Pustular skin involvement was more common in arthritis-first patients (18.3% vs. 11.9% and 16.5% of psoriasis-first and synchronous-onset patients), scalp lesions as the initial lesion were more common in psoriasis-first patients (48.3% vs. 35.2% of arthritis-first patients and 39.8% of synchronous-onset patients), and genital involvement was present more often in arthritis-first patients (12.7% vs. 6.2% and 4.9% of psoriasis-first and synchronous-onset patients).

Early-onset (type 1) psoriasis was more common in psoriasis-first patients (74% vs. 28.1% and 51.8% of arthritis-first and synchronous-onset patients), whereas late-onset (type 2) psoriasis was more common in arthritis-first patients (71.9% vs. 26.0% and 48.2% for psoriasis-first and synchronous-onset patients).

A family history of psoriasis or PsA was more common in psoriasis-first patients (35.6% vs. 26.3% and 28.2% of arthritis-first and synchronous-onset patients), Dr. Kalyoncu said.

Treatment types did not differ between the groups.

Multiple linear regression analysis for the time elapsed from psoriasis to PsA symptom synchronicity, with all other independent variables set to baseline values, showed an overall intercept interval of 66 months, but with nail involvement, family history, or plaque psoriasis, the interval was extended by 28, 24, and 20 months, respectively. However, the presence of pustular psoriasis decreased the intercept interval by 28 months.

A temporal relationship between the onset of skin psoriasis and PsA is a well-known feature of psoriatic disease, with prior studies showing that the majority of cases involve psoriasis-first onset, Dr. Kalyoncu said, adding that heterogeneity in musculoskeletal and skin involvement is also a known feature.

However, little is known about the role of genetics, he noted.

Therefore, he and his colleagues used the Psoriatic Arthritis Registry of Turkey International Database, which was established in 2014 and now also includes data from patients in Canada and Italy, to explore the associations between disease characteristics and the temporal relationship of skin and musculoskeletal disease.

Based on the findings, age at the onset of psoriasis was the main factor that determined PsA symptom synchronicity, he said.

“We know that HLA-Cw6 is important in genetic susceptibility of psoriatic arthritis, but it is important only for early-onset arthritis, not late-onset psoriasis,” Dr. Kalyoncu said. “So our results make an indirect contribution [to the understanding of] these genetic and immunochemical differences between early-onset and late-onset psoriasis, and we need further future studies about this topic.”

Dr. Kalyoncu reported having no relevant disclosures.
