After years of debate and disagreement, could an improved, more user-friendly version of iPLEDGE be on the horizon?

iPLEDGE, the Food and Drug Administration (FDA)–required Risk Evaluation and Mitigation Strategy (REMS) program launched in 2010, aims to manage the risks for the teratogenic acne drug isotretinoin and prevent fetal exposure. But it’s been dogged by issues and controversy, causing difficulties for patients and prescribers.

Late in 2023, there seemed to be a reason for optimism that improvements were coming. On November 30, 2023, the FDA informed isotretinoin manufacturers — known as the Isotretinoin Products Manufacturing Group (IPMG) — that they had 6 months to make five changes to the existing iPLEDGE REMS, addressing the controversies and potentially reducing glitches in the program and minimizing the burden of the program on patients, prescribers, and pharmacies — while maintaining safe use of the drug — and to submit their proposal by May 30, 2024.

The timeline for when an improved program might be in place remains unclear.

An FDA spokesperson, without confirming that the submission was submitted on time, recently said the review timeline once such a submission is received is generally 6 months.
 

‘Radio Silence’

No official FDA announcement has been made about the timeline, nor has information been forthcoming from the IPMG, and the silence has been frustrating for John S. Barbieri, MD, MBA, assistant professor of dermatology at Harvard Medical School and director of the Advanced Acne Therapeutics Clinic at Brigham and Women’s Hospital, both in Boston, Massachusetts. He chairs the American Academy of Dermatology Association’s IPLEDGE Work Group, which works with both the FDA and IPMG.

He began writing about issues with iPLEDGE about 4 years ago, when he and colleagues suggested, among other changes, simplifying the iPLEDGE contraception requirements in a paper published in the Journal of the American Academy of Dermatology.

In an interview, Dr. Barbieri expressed frustration about the lack of information on the status of the iPLEDGE changes. “We’ve been given no timeline [beyond the FDA’s May 30 deadline for the IPMG to respond] of what might happen when. We’ve asked what was submitted. No one will share it with us or tell us anything about it. It’s just radio silence.”

Dr. Barbieri is also frustrated at the lack of response from IPMG. Despite repeated requests to the group to include the dermatologists in the discussions, IPMG has repeatedly declined the help, he said.

IPMG appears to have no dedicated website. No response had been received to an email sent to an address attributed to the group asking if it would share the submission to the FDA.

Currently, isotretinoin, originally marketed as Accutane, is marketed under such brand names as Absorica, Absorica LD, Claravis, Amnesteem, Myorisan, and Zenatane.

Asked for specific information on the proposed changes, an FDA spokesperson said in an August 19 email that “the submission to the FDA from the isotretinoin manufacturers will be a major modification, and the review timeline is generally 6 months. Once approved, the isotretinoin manufacturers will need additional time to implement the changes.”

The spokesperson declined to provide additional information on the status of the IPMG proposal, to share the proposal itself, or to estimate the implementation period.


 

Reason for Hope?

In response to the comment that the review generally takes 6 months, Dr. Barbieri said it doesn’t give him much hope, adding that “any delay of implementing these reforms is a missed opportunity to improve the care of patients with acne.” He is also hopeful that the FDA will invite some public comment during the review period “so that stakeholders can share their feedback about the proposal to help guide FDA decision-making and ensure effective implementation.”
 

From Meeting to Mandate

The FDA order for the changes followed a joint meeting of the FDA’s Drug Safety and Risk Management Advisory Committee and the Dermatologic and Ophthalmic Drugs Advisory Committee in March 2023 about the program requirements. It included feedback from patients and dermatologists and recommendations for changes, with a goal of reducing the burden of the program on patients, pharmacies, and prescribers without compromising patient safety.

The Five Requested Changes

In the November 30 letter, the FDA requested the following from the IPMG:

• Remove the requirement that pregnancy tests be performed in a specially certified lab (such as a Clinical Laboratory Improvement Amendments lab). This would enable the tests to be done in a clinic setting rather than sending patients to a separate lab.
• Allow prescribers the option of letting patients use home pregnancy tests during and after treatment, with steps in place to minimize falsification.
• Remove the waiting period requirement, known as the “19-day lockout,” for patients if they don’t obtain the isotretinoin from the pharmacy within the first 7-day prescription window. Before initiation of isotretinoin, a repeat confirmatory test must be done in a medical setting without any required waiting period.
• Revise the pregnancy registry requirement, removing the objective to document the outcome and associated collection of data for each pregnancy.
• Revise the requirement for prescribers to document patient counseling for those who can’t become pregnant from monthly counseling to counseling at enrollment only. Before each prescription is dispensed, the authorization must verify patient enrollment and prescriber certification. (In December 2021, a new, gender-neutral approach, approved by the FDA, was launched. It places potential patients into two risk categories — those who can become pregnant and those who cannot. Previously, there were three such categories: Females of reproductive potential, females not of reproductive potential, and males.)

Perspective on the Requested Changes

Of the requested changes, “really the most important is eliminating the request for monthly counseling for patients who cannot become pregnant,” Dr. Barbieri said. Because of that requirement, all patients need to have monthly visits with a dermatologist to get the medication refills, “and that creates a logistical barrier,” plus reducing time available for dermatologists to care for other patients with other dermatologic issues.

As for missing the 7-day prescription window, Dr. Barbieri said, in his experience, “it’s almost never the patient’s fault; it’s almost always an insurance problem.”

Dr. Barbieri reported no relevant conflicts of interest.

TOPLINE:

Compared with dipeptidyl peptidase 4 (DPP-4) inhibitors, glucagon-like peptide 1 receptor agonists (GLP-1 RAs) are associated with a lower risk for all-cause mortality and major adverse cardiovascular events (MACE) in patients with immune-mediated inflammatory diseases (IMIDs) and type 2 diabetes (T2D).

METHODOLOGY:

• GLP-1 RAs reduce the risk for all-cause mortality, cardiovascular mortality, and stroke in patients with diabetes. However, previous trials have excluded those with IMIDs, leaving a gap in understanding the cardioprotective effects of GLP-1 RAs in this population.
• Researchers conducted a population-based cohort study to assess if patients with an IMID derive greater benefits from GLP-1 RAs than DPP-4 inhibitors.
• They used administrative health data from British Columbia, Canada, to include 10,855 patients with IMIDs (rheumatoid arthritis, psoriatic disease, ankylosing spondylitis, inflammatory bowel disease, or systemic autoimmune rheumatic disease) and T2D who initiated either GLP-1 RA (n = 3570) or DPP-4 inhibitor (n = 7285).
• The mean follow-up was 1.46 and 1.88 years in the GLP-1 RA and DPP-4 inhibitor cohorts, respectively.
• The primary outcome was all-cause mortality, and the secondary outcome was MACE, including cardiovascular death, myocardial infarction, and ischemic stroke.

TAKEAWAY:

• The risk for all-cause mortality was 52% lower in patients who initiated GLP-1 RAs than in those who initiated DPP-4 inhibitors (weighted hazard ratio [HR], 0.48; 95% CI, 0.31-0.75).
• Additionally, patients initiating DPP-4 inhibitors.
• In the subgroup of patients with GLP-1 RAs had a significantly lower risk for MACE (weighted HR, 0.66; 95% CI, 0.50-0.88), particularly myocardial infarction (weighted HR, 0.62; 95% CI, 0.40-0.96), than those initiating rheumatoid arthritis and T2D, those who initiated GLP-1 RAs had a 55% lower risk for all-cause mortality and 61% lower risk for MACE than those who initiated DPP-4 inhibitors.

IN PRACTICE:

“This corresponds to nine fewer deaths and 11 fewer MACE per 1000 person-years, respectively, supporting the hypothesis that these agents have a cardioprotective effect in this high-risk population,” the authors wrote.

SOURCE:

This study was led by Derin Karacabeyli, MD, Division of Rheumatology, Department of Medicine, University of British Columbia, Vancouver, Canada, and was published online on August 8, 2024, in PLOS ONE.

LIMITATIONS:

The study’s dependence on administrative health data might have resulted in incomplete capture of comorbidities, particularly obesity. The mean follow-up period was relatively short, which might have limited the long-term applicability of these findings. The accuracy of the case definitions for IMIDs and T2D, according to International Classification of Diseases codes, could not be fully ascertained.

DISCLOSURES:

The study was supported by grants from the Canadian Institutes of Health Research. Two authors declared receiving research support, consulting fees, or participating in advisory boards outside the submitted work.

Since the first Food and Drug Administration approval of a Janus kinase (JAK) inhibitor in 2011, the number of these medications available — and their treatment indications — have continued to grow. Prescribing physicians are familiar with the benefits and risks for these drugs, including higher risk for cardiac events and malignancy; however, one adverse effect may be overlooked, especially by specialties outside of dermatology: acne. Though less serious than some other side effects, JAK inhibitor–associated acne — JAKne, for short — can be a concern for patients.

“Your physical appearance and how you present yourself to the world is an important part of your self-confidence and living life on your own terms,” said Arash Mostaghimi, MD, the director of inpatient dermatology at Brigham and Women’s Hospital in Boston, Massachusetts. “I think letting people know about [JAKne] and then addressing it when it occurs should be a normal part of managing these medications.”
 

What Is JAKne?

JAKne generally looks like other kinds of acne, explained Janelle Nassim, MD, director of laser and cosmetic dermatology at the Indiana University School of Medicine, Indianapolis. “It can affect the same areas that typical acne affects, including the face, chest, back, neck, and upper shoulders.”

Though it appears like typical forms of acne, it is not clear what drives these skin eruptions in patients taking JAK inhibitors.

“We don’t understand the underlying pathophysiology,” Dr. Mostaghimi said. “It looks like acne, but we don’t know if the exact underlying inflammatory process is the same or if it’s different.”

In a 2023 systematic review of clinical studies, Dr. Mostaghimi and colleagues found that patients on any JAK inhibitor were nearly four times more likely to experience acne than patients who received placebo, but risk varied between medications. Patients taking JAK inhibitors for skin conditions had higher risk for acne than those given the medications for other indications. However, Dr. Mostaghimi thinks this finding is the result of selection bias.

Participants may not mention side effects like acne in trials for rheumatologic or gastrointestinal conditions, he said, unlike in trials for skin conditions. “Clinically, I’ve seen it in patients across every indication.”

Patients with a history of acne seem to be more likely to develop this side effect, though formal studies looking into risk factors are lacking. In Dr. Mostaghimi’s own clinical experience, JAKne is also more common in younger patients, but it can happen to anyone. “I’ve seen 70-year-olds develop acne — patients who’ve never had an issue their whole life — when they’re taking a JAK inhibitor.”

This issue also appears to be more common earlier in treatment, he added, and may improve over time as a patient continues with the medication.
 

How Do You Treat It?

“I think in other specialties, you will often feel awkward addressing skin conditions or pointing out acne,” Dr. Mostaghimi said. The most important steps are being aware of this potential side effect, and if you see it practice, to bring it up.

“Say: I’m noticing there’s some changes in your skin. Some patients on JAK inhibitors develop more acne. Have you noticed this? And if so, is this bothering you?”

Generally, JAKne is mild to moderate, explained Dr. Nassim, and if non-dermatologists are comfortable, they can prescribe a first-line topical regimen for patients. Dr. Mostaghimi recommends prescribing a clindamycin 1% lotion or gel. In addition, patients can use a benzoyl peroxide wash (4% or 10%) combined with a gentle retinoid, such as adapalene. (Both of these treatments are now available over the counter.)

In patients with scalp or hairline involvement, he often prescribes a ketoconazole 2% shampoo, which patients can use to wash their scalp, face, chest, and back in the shower.

If they aren’t responding to these initial treatments, then refer to a dermatologist for further assessment.

“Ultimately, referring to a dermatologist is the best course of action,” Dr. Nassim said. “I have had patients on JAK inhibitors who improved with topical acne treatments, and some that required more aggressive treatment with oral medications.”

Dr. Mostaghimi reported consulting fees from AbbVie, Concert Pharmaceuticals, Pfizer, and 3Derm Systems; research funding from Incyte, Aclaris Therapeutics, Eli Lilly, and Concert Pharmaceuticals; personal fees from Equillium, ASLAN Pharmaceuticals, ACOM, and Boehringer Ingelheim; and advisory board fees from Fig.1 Beauty, Eli Lilly, Pfizer, and Hims & Hers Health. Dr. Nassim had no relevant disclosures.

JAKne generally looks like other kinds of acne, explained Janelle Nassim, MD, director of laser and cosmetic dermatology at the Indiana University School of Medicine, Indianapolis. “It can affect the same areas that typical acne affects, including the face, chest, back, neck, and upper shoulders.”

Though it appears like typical forms of acne, it is not clear what drives these skin eruptions in patients taking JAK inhibitors.

“We don’t understand the underlying pathophysiology,” Dr. Mostaghimi said. “It looks like acne, but we don’t know if the exact underlying inflammatory process is the same or if it’s different.”

In a 2023 systematic review of clinical studies, Dr. Mostaghimi and colleagues found that patients on any JAK inhibitor were nearly four times more likely to experience acne than patients who received placebo, but risk varied between medications. Patients taking JAK inhibitors for skin conditions had higher risk for acne than those given the medications for other indications. However, Dr. Mostaghimi thinks this finding is the result of selection bias.

Participants may not mention side effects like acne in trials for rheumatologic or gastrointestinal conditions, he said, unlike in trials for skin conditions. “Clinically, I’ve seen it in patients across every indication.”

Patients with a history of acne seem to be more likely to develop this side effect, though formal studies looking into risk factors are lacking. In Dr. Mostaghimi’s own clinical experience, JAKne is also more common in younger patients, but it can happen to anyone. “I’ve seen 70-year-olds develop acne — patients who’ve never had an issue their whole life — when they’re taking a JAK inhibitor.”

This issue also appears to be more common earlier in treatment, he added, and may improve over time as a patient continues with the medication.
 

How Do You Treat It?

“I think in other specialties, you will often feel awkward addressing skin conditions or pointing out acne,” Dr. Mostaghimi said. The most important steps are being aware of this potential side effect, and if you see it practice, to bring it up.

“Say: I’m noticing there’s some changes in your skin. Some patients on JAK inhibitors develop more acne. Have you noticed this? And if so, is this bothering you?”

Generally, JAKne is mild to moderate, explained Dr. Nassim, and if non-dermatologists are comfortable, they can prescribe a first-line topical regimen for patients. Dr. Mostaghimi recommends prescribing a clindamycin 1% lotion or gel. In addition, patients can use a benzoyl peroxide wash (4% or 10%) combined with a gentle retinoid, such as adapalene. (Both of these treatments are now available over the counter.)

In patients with scalp or hairline involvement, he often prescribes a ketoconazole 2% shampoo, which patients can use to wash their scalp, face, chest, and back in the shower.

If they aren’t responding to these initial treatments, then refer to a dermatologist for further assessment.

“Ultimately, referring to a dermatologist is the best course of action,” Dr. Nassim said. “I have had patients on JAK inhibitors who improved with topical acne treatments, and some that required more aggressive treatment with oral medications.”

Dr. Mostaghimi reported consulting fees from AbbVie, Concert Pharmaceuticals, Pfizer, and 3Derm Systems; research funding from Incyte, Aclaris Therapeutics, Eli Lilly, and Concert Pharmaceuticals; personal fees from Equillium, ASLAN Pharmaceuticals, ACOM, and Boehringer Ingelheim; and advisory board fees from Fig.1 Beauty, Eli Lilly, Pfizer, and Hims & Hers Health.

Since the first Food and Drug Administration approval of a Janus kinase (JAK) inhibitor in 2011, the number of these medications available — and their treatment indications — have continued to grow. Prescribing physicians are familiar with the benefits and risks for these drugs, including higher risk for cardiac events and malignancy; however, one adverse effect may be overlooked, especially by specialties outside of dermatology: acne. Though less serious than some other side effects, JAK inhibitor–associated acne — JAKne, for short — can be a concern for patients.

Systemic amyloidosis is a rare and complex disease characterized by the extracellular deposition of misfolded proteins, known as amyloid fibrils, in various tissues and organs. This heterogeneous disorder can present with a wide range of clinical manifestations, including dermatological symptoms that may be the first or predominant feature. Systemic amyloidosis is characterized by macroglossia, periorbital purpura, and waxy skin plaques. Lateral scalloping of the tongue may be seen due to impingement of the teeth. Cutaneous amyloidosis occurs when amyloid is deposited in the skin, without internal organ involvement. Variants of cutaneous amyloidosis include macular, lichen, nodular and biphasic.

This condition requires a thorough diagnostic workup, including serum and urine protein electrophoresis and biopsy of the affected tissue. Biopsy of a cutaneous amyloidosis lesion will show fractured, amorphous, eosinophilic material in the dermis. Pigment and epidermal changes are often found with cutaneous amyloidosis, including hyperkeratosis, acanthosis, hypergranulosis, parakeratosis, and epidermal atrophy. Stains that may be used include Congo red showing apple-green birefringence, thioflavin T, and crystal violet.

If untreated, the prognosis is generally poor, related to the extent of organ involvement. Cardiac involvement, a common feature of systemic amyloidosis, can lead to restrictive cardiomyopathy, heart failure, and arrhythmias. Management strategies include steroids, chemotherapy, and stem cell transplantation. Medications include dexamethasone, cyclophosphamide, bortezomib, and melphalan.

WASHINGTON, DC — Cutaneous immune-related adverse events (cirAEs) in oncology patients receiving immune checkpoint inhibitors (ICIs) should be treated in as targeted a fashion as possible and with judicious usage and dosing of prednisone when deemed necessary, Blair Allais, MD, said during a session on supportive oncodermatology at the ElderDerm conference on dermatology in the older patient hosted by the George Washington University School of Medicine and Health Sciences, Washington, DC.

“It’s important when you see these patients to be as specific as possible” based on morphology and histopathology, and to treat the rashes in a similar way as in the non-ICI setting,” said Dr. Allais, a dermato-oncologist at the Inova Schar Cancer Institute, Fairfax, Virginia.

cirAEs are the most frequently reported and most visible adverse effects of checkpoint inhibition — a treatment that has emerged as a standard therapy for many malignancies since the first ICI was approved in 2011 for metastatic melanoma.

And contrary to what the phenomenon of immunosenescence might suggest, older patients are no less prone to cirAEs than younger patients. “You’d think you’d have fewer rashes and side effects as you age, but that’s not true,” said Dr. Allais, who completed a fellowship in cutaneous oncology after her dermatology residency.

A 2021 multicenter international cohort study of over 900 patients aged ≥ 80 years treated with single-agent ICIs for cancer did not find any significant differences in the development of immune-related adverse events among those younger than 85, those aged 85-89 years, and those 90 and older. Neither did the ELDERS study in the United Kingdom; this prospective observational study found similar rates of high-grade and low-grade immune toxicity in its two cohorts of patients ≥ 70 and < 70 years of age.

At the meeting, Dr. Allais, who coauthored a 2023 review of cirAEs from ICIs, reviewed recent developments and provided the following advice:
 

New diagnostic criteria: “Really exciting” news for more precise diagnosis and optimal therapy of cirAEs, Dr. Allais said, is a position paper published in the Journal for ImmunoTherapy of Cancer that offers consensus-based diagnostic criteria for the 10 most common types of dermatologic immune-related adverse events and an overall diagnostic framework. “Luckily, through the work of a Delphi consensus group, we can now have [more diagnostic specificity],” which is important for both clinical care and research, she said.

Most cirAEs have typically been reported nonspecifically as “rash,” but diagnosing a rash subtype is “critical in tailoring appropriate therapy that it is both effective and the least detrimental to the oncology treatment plan for patients with cancer,” the group’s coauthors wrote.

The 10 core diagnoses include psoriasis, eczematous dermatitis, vitiligo, Grover disease, eruptive atypical squamous proliferation, and bullous pemphigoid. Outside of the core diagnoses are other nonspecific presentations that require evaluation to arrive at a diagnosis, if possible, or to reveal data that can allow for targeted therapy and severity grading, the group explains in its paper.

“To prednisone or not to prednisone”: The development of cirAEs is associated with reduced mortality and improved cancer outcomes, making the use of immunosuppressants such as corticosteroids a therapeutic dilemma. “Patients who get these rashes usually do better with respect to their cancer, so the concern has been, if we affect how they respond to their immunotherapy, we may minimize that improvement in mortality,” said Dr. Allais, also assistant professor at the University of Virginia, Charlottesville, and clinical assistant professor of dermatology at George Washington University.

A widely discussed study published in 2015 reported on 254 patients with melanoma who developed an immune-related adverse event during treatment with ipilimumab — approximately one third of whom required systemic corticosteroids — and concluded that systemic corticosteroids did not affect overall survival or time to (cancer) treatment failure. This study from Memorial Sloan Kettering Cancer Center, New York City, “was the first large study looking at this question,” she said, and the subsequent message for several years in conferences and the literature was that steroids do not affect the efficacy of checkpoint inhibitors.

“But the study was not without limitations,” Dr. Allais said, “because the patients who got prednisone were mainly those with higher-grade toxicities,” while those not treated with corticosteroids had either no toxicities or low-grade toxicities. “If higher-grade toxicities were associated with better (antitumor) response, the steroids may have just [blunted] that benefit.”

The current totality of data available in the literature suggests that corticosteroids may indeed have an impact on the efficacy of ICI therapy. “Subsequent studies have come out in the community that have shown that we should probably think twice about giving prednisone to some patients, particularly within the first 50 days of ICI treatment, and that we should be mindful of the dose,” Dr. Allais said.

The takeaways from these studies — all published in the past few years — are to use prednisone early and liberally for life-threatening toxicity, to use it at the lowest dose and for the shortest course when there is not an appropriate alternative, to avoid it for diagnoses that are not treated with prednisone outside the ICI setting, and to “have a plan” for a steroid-sparing agent to use after prednisone, she said.

Dr. Allais recommends heightened consideration during the first 50 days of ICI treatment based on a multicenter retrospective study that found a significant association between use of high-dose glucocorticoids (≥ 60 mg prednisone equivalent once a day) within 8 weeks of anti–programmed cell death protein 1 (PD-1) monotherapy initiation and poorer progression-free and overall survival. The study covered a cohort of 947 patients with advanced melanoma treated with anti–PD-1 monotherapy between 2009 and 2019, 54% of whom developed immune-related adverse events.

This study and other recent studies addressing the association between steroids and survival outcomes in patients with immune-related adverse events during ICI therapy are described in Dr. Allais’ 2023 review of cirAEs from ICIs.

Approach to morbilliform eruptions: This rash is “super common” in patients on ICIs, occurring generally within 2-3 weeks of starting treatment. “It tends to be self-limited and can recur with future infusions,” Dr. Allais said.

Systemic steroids should be reserved for severe or refractory eruptions. “Usually, I treat the patients with topical steroids, and I manage their expectations (that the rash may recur with subsequent infusions), but I closely follow them up” within 2-3 weeks, she said. It’s important to rule out a severe cutaneous adverse drug eruption, of course, and to start high-dose systemic steroids immediately if necessary. “Antibiotics are a big culprit” and often can be discontinued.

Soak and smear: “I’m obsessed” with this technique of a 20-minute soak in plain water followed by application of steroid ointment, said Dr. Allais, referring to a small study published in 2005 that reported a complete response after 2 weeks in 60% of patients with psoriasis, atopic dermatitis, and other inflammatory skin conditions (none had cancer), who had failed prior systemic therapy. All patients had at least a 75% response.

The method offers a way to “avoid the systemic immunosuppression we’d get with prednisone,” she said. One just needs to make sure the older patient can get in and out of their tub safely.

ICI-induced bullous pemphigoid (BP): BP occurs more frequently in the ICI setting, compared with the general population, with a median time to development of 8.5 months after ICI initiation. It is associated in this setting with improved tumor response, but “many oncologists stop anticancer treatment because of this diagnosis,” she said.

In the supportive oncodermatology space, however, ICI-induced BP exemplifies the value of tailored treatment regimens, she said. A small multi-institutional retrospective cohort study published in 2023 identified 35 cases of ICI-BP among 5636 ICI-treated patients and found that 8 out of 11 patients who received biologic therapy (rituximab, omalizumab, or dupilumab) had a complete response to ICI-BP without flares following subsequent ICI cycles. And while statistical significance was not reached, the study showed that no cancer-related outcomes were worsened.

“If you see someone with ICI-induced BP and they have a lot of involvement, you could start them on steroids and get that steroid-sparing agent initiated for approval. ... And if IgE is elevated, you might reach for omalizumab,” said Dr. Allais, noting that her favored treatment overall is dupilumab.

Risk factors for the development of ICI-induced BP include age > 70, skin cancer, and having an initial response to ICI on first imaging, the latter of which “I find fascinating ... because imaging occurs within the first 12 weeks of treatment, but we don’t see BP popping up until 8.5 months into treatment,” she noted. “So maybe there’s a baseline risk factor that could predispose them.”

Caution with antibiotics: “I try to avoid antibiotics in the ICI setting,” Dr. Allais said, in deference to the “ever-important microbiome.” Studies have demonstrated that the microbiomes of responders to ICI treatment are different from those of nonresponders, she said.

And a “fascinating” study of patients with melanoma undergoing ICI therapy showed not only a higher abundance of Ruminococcaceae bacteria in responders vs nonresponders but a significant impact of dietary fiber. High dietary fiber was associated with significantly improved overall survival in the patients on ICI, with the most pronounced benefit in patients with good fiber intake and no probiotic use. “Even wilder, their T cells changed,” she said. “They had a high expression of genes related to T-cell activation ... so more tumor-infiltrating lymphocytes.”

A retrospective study of 568 patients with stages III and IV melanoma treated with ICI showed that those exposed to antibiotics prior to ICI had significantly worse overall survival than those not exposed to antibiotics. “Think before you give them,” Dr. Allais said. “And try to tell your older patients to eat beans and greens.”

Dr. Allais reported having no relevant disclosures.

A small multi-institutional retrospective cohort study published in 2023 identified 35 cases of ICI-BP among 5636 ICI-treated patients and found that 8 out of 11 patients who received biologic therapy (rituximab, omalizumab, or dupilumab) had a complete response to ICI-BP without flares following subsequent ICI cycles. And while statistical significance was not reached, the study showed that no cancer-related outcomes were worsened.

“If you see someone with ICI-induced BP and they have a lot of involvement, you could start them on steroids and get that steroid-sparing agent initiated for approval. ... And if IgE is elevated, you might reach for omalizumab,” said Dr. Allais, noting that her favored treatment overall is dupilumab.

Risk factors for the development of ICI-induced BP include age > 70, skin cancer, and having an initial response to ICI on first imaging, the latter of which “I find fascinating ... because imaging occurs within the first 12 weeks of treatment, but we don’t see BP popping up until 8.5 months into treatment,” she noted. “So maybe there’s a baseline risk factor that could predispose them.”

Caution with antibiotics: “I try to avoid antibiotics in the ICI setting,” Dr. Allais said, in deference to the “ever-important microbiome.” Studies have demonstrated that the microbiomes of responders to ICI treatment are different from those of nonresponders, she said.

And a “fascinating” study of patients with melanoma undergoing ICI therapy showed not only a higher abundance of Ruminococcaceae bacteria in responders vs nonresponders but a significant impact of dietary fiber. High dietary fiber was associated with significantly improved overall survival in the patients on ICI, with the most pronounced benefit in patients with good fiber intake and no probiotic use. “Even wilder, their T cells changed,” she said. “They had a high expression of genes related to T-cell activation ... so more tumor-infiltrating lymphocytes.”

A retrospective study of 568 patients with stages III and IV melanoma treated with ICI showed that those exposed to antibiotics prior to ICI had significantly worse overall survival than those not exposed to antibiotics. “Think before you give them,” Dr. Allais said. “And try to tell your older patients to eat beans and greens.”

Dr. Allais reported having no relevant disclosures.

WASHINGTON, DC — Cutaneous immune-related adverse events (cirAEs) in oncology patients receiving immune checkpoint inhibitors (ICIs) should be treated in as targeted a fashion as possible and with judicious usage and dosing of prednisone when deemed necessary, Blair Allais, MD, said during a session on supportive oncodermatology at the ElderDerm conference on dermatology in the older patient hosted by the George Washington University School of Medicine and Health Sciences, Washington, DC.

“It’s important when you see these patients to be as specific as possible” based on morphology and histopathology, and to treat the rashes in a similar way as in the non-ICI setting,” said Dr. Allais, a dermato-oncologist at the Inova Schar Cancer Institute, Fairfax, Virginia.

cirAEs are the most frequently reported and most visible adverse effects of checkpoint inhibition — a treatment that has emerged as a standard therapy for many malignancies since the first ICI was approved in 2011 for metastatic melanoma.

And contrary to what the phenomenon of immunosenescence might suggest, older patients are no less prone to cirAEs than younger patients. “You’d think you’d have fewer rashes and side effects as you age, but that’s not true,” said Dr. Allais, who completed a fellowship in cutaneous oncology after her dermatology residency.

A 2021 multicenter international cohort study of over 900 patients aged ≥ 80 years treated with single-agent ICIs for cancer did not find any significant differences in the development of immune-related adverse events among those younger than 85, those aged 85-89 years, and those 90 and older. Neither did the ELDERS study in the United Kingdom; this prospective observational study found similar rates of high-grade and low-grade immune toxicity in its two cohorts of patients ≥ 70 and < 70 years of age.

At the meeting, Dr. Allais, who coauthored a 2023 review of cirAEs from ICIs, reviewed recent developments and provided the following advice:
 

New diagnostic criteria: “Really exciting” news for more precise diagnosis and optimal therapy of cirAEs, Dr. Allais said, is a position paper published in the Journal for ImmunoTherapy of Cancer that offers consensus-based diagnostic criteria for the 10 most common types of dermatologic immune-related adverse events and an overall diagnostic framework. “Luckily, through the work of a Delphi consensus group, we can now have [more diagnostic specificity],” which is important for both clinical care and research, she said.

Most cirAEs have typically been reported nonspecifically as “rash,” but diagnosing a rash subtype is “critical in tailoring appropriate therapy that it is both effective and the least detrimental to the oncology treatment plan for patients with cancer,” the group’s coauthors wrote.

The 10 core diagnoses include psoriasis, eczematous dermatitis, vitiligo, Grover disease, eruptive atypical squamous proliferation, and bullous pemphigoid. Outside of the core diagnoses are other nonspecific presentations that require evaluation to arrive at a diagnosis, if possible, or to reveal data that can allow for targeted therapy and severity grading, the group explains in its paper.

“To prednisone or not to prednisone”: The development of cirAEs is associated with reduced mortality and improved cancer outcomes, making the use of immunosuppressants such as corticosteroids a therapeutic dilemma. “Patients who get these rashes usually do better with respect to their cancer, so the concern has been, if we affect how they respond to their immunotherapy, we may minimize that improvement in mortality,” said Dr. Allais, also assistant professor at the University of Virginia, Charlottesville, and clinical assistant professor of dermatology at George Washington University.

A widely discussed study published in 2015 reported on 254 patients with melanoma who developed an immune-related adverse event during treatment with ipilimumab — approximately one third of whom required systemic corticosteroids — and concluded that systemic corticosteroids did not affect overall survival or time to (cancer) treatment failure. This study from Memorial Sloan Kettering Cancer Center, New York City, “was the first large study looking at this question,” she said, and the subsequent message for several years in conferences and the literature was that steroids do not affect the efficacy of checkpoint inhibitors.

“But the study was not without limitations,” Dr. Allais said, “because the patients who got prednisone were mainly those with higher-grade toxicities,” while those not treated with corticosteroids had either no toxicities or low-grade toxicities. “If higher-grade toxicities were associated with better (antitumor) response, the steroids may have just [blunted] that benefit.”

The current totality of data available in the literature suggests that corticosteroids may indeed have an impact on the efficacy of ICI therapy. “Subsequent studies have come out in the community that have shown that we should probably think twice about giving prednisone to some patients, particularly within the first 50 days of ICI treatment, and that we should be mindful of the dose,” Dr. Allais said.

The takeaways from these studies — all published in the past few years — are to use prednisone early and liberally for life-threatening toxicity, to use it at the lowest dose and for the shortest course when there is not an appropriate alternative, to avoid it for diagnoses that are not treated with prednisone outside the ICI setting, and to “have a plan” for a steroid-sparing agent to use after prednisone, she said.

Dr. Allais recommends heightened consideration during the first 50 days of ICI treatment based on a multicenter retrospective study that found a significant association between use of high-dose glucocorticoids (≥ 60 mg prednisone equivalent once a day) within 8 weeks of anti–programmed cell death protein 1 (PD-1) monotherapy initiation and poorer progression-free and overall survival. The study covered a cohort of 947 patients with advanced melanoma treated with anti–PD-1 monotherapy between 2009 and 2019, 54% of whom developed immune-related adverse events.

This study and other recent studies addressing the association between steroids and survival outcomes in patients with immune-related adverse events during ICI therapy are described in Dr. Allais’ 2023 review of cirAEs from ICIs.

Approach to morbilliform eruptions: This rash is “super common” in patients on ICIs, occurring generally within 2-3 weeks of starting treatment. “It tends to be self-limited and can recur with future infusions,” Dr. Allais said.

Systemic steroids should be reserved for severe or refractory eruptions. “Usually, I treat the patients with topical steroids, and I manage their expectations (that the rash may recur with subsequent infusions), but I closely follow them up” within 2-3 weeks, she said. It’s important to rule out a severe cutaneous adverse drug eruption, of course, and to start high-dose systemic steroids immediately if necessary. “Antibiotics are a big culprit” and often can be discontinued.

Soak and smear: “I’m obsessed” with this technique of a 20-minute soak in plain water followed by application of steroid ointment, said Dr. Allais, referring to a small study published in 2005 that reported a complete response after 2 weeks in 60% of patients with psoriasis, atopic dermatitis, and other inflammatory skin conditions (none had cancer), who had failed prior systemic therapy. All patients had at least a 75% response.

The method offers a way to “avoid the systemic immunosuppression we’d get with prednisone,” she said. One just needs to make sure the older patient can get in and out of their tub safely.

ICI-induced bullous pemphigoid (BP): BP occurs more frequently in the ICI setting, compared with the general population, with a median time to development of 8.5 months after ICI initiation. It is associated in this setting with improved tumor response, but “many oncologists stop anticancer treatment because of this diagnosis,” she said.

In the supportive oncodermatology space, however, ICI-induced BP exemplifies the value of tailored treatment regimens, she said. A small multi-institutional retrospective cohort study published in 2023 identified 35 cases of ICI-BP among 5636 ICI-treated patients and found that 8 out of 11 patients who received biologic therapy (rituximab, omalizumab, or dupilumab) had a complete response to ICI-BP without flares following subsequent ICI cycles.

On August 13, 2024, the Food and Drug Administration (FDA) approved nemolizumab for the treatment of adults with prurigo nodularis (PN).

A first-in-class monoclonal antibody specifically designed to inhibit interleukin (IL)–31 signaling, nemolizumab, will be available in a prefilled pen for subcutaneous injection and will be marketed as Nemluvio. It is currently under FDA review for treating atopic dermatitis in adolescents and adults. 

Approval for PN is based on data from the phase 3 OLYMPIA clinical trial program, which evaluated the efficacy and safety of nemolizumab administered subcutaneously every 4 weeks in 560 patients with PN, according to a press release from Galderma, the manufacturer.

According to the press release, in OLYMPIA 1 and OLYMPIA 2, 58% and 56% of patients, respectively, achieved at least a 4-point reduction in itch intensity at week 16 as measured by the Peak Pruritus Numerical Rating Scale, compared with 16% in both placebo groups (P < .0001). At the same time, 26% and 38% of nemolizumab-treated patients reached clearance or almost-clearance of skin lesions on the Investigator Global Assessment score at week 16, compared with 7% and 11% in the placebo groups (P < .0001).

According to the company press release, the most common side effects of nemolizumab are headache and rashes in the form of eczema, atopic dermatitis, and nummular eczema. 

“By inhibiting the signaling of IL-31, Nemluvio addresses a key driver of prurigo nodularis, safely and effectively improving itch as well as skin nodules,” Shawn G. Kwatra, MD, PhD, professor and chair of dermatology at the University of Maryland School of Medicine, Baltimore, and lead investigator of the OLYMPIA program, stated in the press release.

The regulatory submission of nemolizumab in atopic dermatitis is based on data from the phase 3 ARCADIA clinical trial program, which evaluated the efficacy and safety of nemolizumab administered subcutaneously every 4 weeks in adolescents and adults with moderate to severe atopic dermatitis. A decision on approval for this indication from the FDA is expected in December 2024.

In September 2022, dupilumab became the first FDA-approved treatment for PN in the United States.

TORONTO — Reading a storybook about embracing differences can reduce anxiety and boost self-esteem in children with a visible skin condition, the early results of an ongoing study suggested.

So far, “the study demonstrates that these books have value to patients and families,” one of the study authors, Sonia Havele, MD, a pediatrician and dermatology resident at Children’s Mercy Hospital Kansas City, Kansas City, Missouri, said in an interview.

“There are tools to help kids cope with their skin conditions, but we’re underutilizing them,” she added. “And part of the reason we’re underutilizing storybooks is that we just don’t know what’s out there.” For the study, the researchers received funding to purchase 18 “creative and thoughtful” storybooks related to pediatric skin conditions, reviewed by at least two pediatric dermatologists before being selected, which are just a sample of related books that are available.

The study results were presented as a poster at the annual meeting of the Society for Pediatric Dermatology.

Children with visible skin conditions, which can include port-wine stains, capillary malformations, and congenital moles, may be subjected to teasing or bullying at school, and the conditions can also affect their quality of life.
 

Beauty and the Birthmark

The books include one titled “Beauty with a Birthmark” and another, “My Hair Went on Vacation.” An illustrated book, “Just Ask: Be Different, Be Brave, Be You,” by US Supreme Court Justice Sonia Sotomayor, offers tips on how to answer common questions about someone’s appearance.

Dr. Havele said that Justice Sotomayor’s book “empowers kids, their siblings, their classmates ... to ask questions, and it teaches patients not to be afraid of those questions, and to really lean into educating their peers, and their family members.”

“Kids are really just curious,” she added. “They’ll make comments like: ‘Hey, what’s that spot on your face?’ Or, they’ll ask about vitiligo because they’ve never seen somebody with it before.”

To evaluate the psychosocial impact of these types of books for children with visible skin conditions, Dr. Havele and colleagues designed a study that includes patients aged 2-12 years dealing with issues related to self-esteem, acceptance, coping, or bullying. Parents are provided with a relevant storybook to read at home with their child in a “safe and comfortable space” and “at their own pace and their own time,” said Dr. Havele.

Inside the book is a QR code to access the validated Children’s Dermatology Life Quality Index (CDLQI). Families complete the survey at baseline and provide feedback after reading the book. Researchers collect information about demographics, age, gender, and skin conditions, which included atopic dermatitis, alopecia areata, vitiligo, hemangioma, and port-wine stain.

The response rate so far is 34%, and close to 80 parents have completed the survey with their child, Dr. Havele said.

At baseline, many of the children were either moderately or severely affected in terms of their quality of life (45% scored ≥ 6 on the CDLQI).

After reading the book, about 80% of parents reported it had a positive impact, and about 20% said it had a somewhat positive impact on their child’s self-image or confidence. Almost 80% agreed, and the remainder somewhat agreed it encouraged their child to embrace differences.

Most respondents also said the book helped the parent and child cope with the child’s condition. “So really, it was overall a positive response,” said Dr. Havele. “We are able to demonstrate that these books have value in a more scientific or objective way.”

This may not be surprising. Dr. Havele referred to more formal bibliotherapy (book therapy), which has been studied in other pediatric populations, including patients with cancer and those who have experienced trauma.
 

Awesome Space

Pediatric dermatologists are perfectly positioned to play a role in improving the lives of their patients with skin issues. “We see the impact of visible skin disease on children all the time,” said Dr. Havele. “The dermatology visit is an awesome space and opportunity to introduce these books to families and potentially help them talk about the skin condition with their child.”

In addition to prescribing therapies, “we’re also with these kids through an emotional journey, and I think giving them tools for that emotional journey is very helpful,” she added.

Such books would have been a great help to Dr. Havele herself. Growing up, she had severe atopic dermatitis covering much of her body. “Having such a resource would have helped me better cope with my reality of being different than everyone else.”

She hopes a database will be established to house these resources so other providers can refer patients to the list of books. Other books include “The Itchy-saurus: The Dino with an itch that can’t be scratched,” “Hair in My Brush,” and “I am Unique!”

Dr. Havele had no relevant disclosures.

Emerging diagnostic technology that uses artificial intelligence (AI) has demonstrated the potential to free dermatologists from the burden of triaging skin lesions, but dermatology lags behind some other specialties in harnessing the power of AI, and confusion surrounds dermatologists’ role in using this technology, according to researchers and dermatologists investigating AI.

While some AI-integrated devices designed to triage skin lesions have emerged, including one that received Food and Drug Administration (FDA) clearance earlier in 2024, it may be some time before AI has a meaningful clinical impact in dermatology and, more specifically, the diagnosis of skin cancer, Ivy Lee, MD, a dermatologist in Pasadena, California, and chair of the American Academy of Dermatology’s augmented intelligence committee, told this news organization.

“It hasn’t really translated into clinical practice yet,” Dr. Lee said of AI in dermatology. “There have been significant advances in terms of the technical possibility and feasibility of these tools, but the translation and integration of AI into actual clinical work flows to benefit patients beyond academic research studies has been limited.” More studies and more “easily accessible and digestible information” are needed to evaluate AI tools in dermatologic practice.

“In dermatology, we’re on a cusp with AI,” said Rebecca Hartman, MD, MPH, chief of dermatology at the VA Boston Healthcare System and director of melanoma epidemiology at Brigham and Women’s Hospital, Boston, Massachusetts. “I think it’s going to come and change what we do,” which is especially true for any image-based specialty,” including radiology and pathology, in addition to dermatology.

Dr. Hartman led a study of one of these emerging technologies, the handheld elastic scattering spectroscopy device DermaSensor, which was cleared by the FDA in January for evaluating skin lesions suggestive of skin cancer.
 

Early AI Devices for Skin Cancer Detection

At the American Society for Laser Medicine and Surgery (ASLMS) meeting in April, a panel explored a number of algorithms with dermatologic applications that use AI to triage skin lesions, including DermaSensor.

Raman spectroscopy, which contains a handheld Raman probe, a diode laser, and a detecting spectrograph. A laser beam — which at 1.56 W/cm² is below the maximum permissible exposure — focuses on the skin target with a 3.5-mm spot, gathers data on the target, and feeds it back into the unit that houses the algorithm that evaluates the spot analysis. It’s still in the investigative phase. A clinical trial, published almost 5 years ago, demonstrated a sensitivity of 90%-99% and a specificity of 24%-66% for skin cancer.

A dermatoscope called Sklip clips onto a smartphone and performs what company cofounder Alexander Witkowski, MD, PhD, described as an “optical painless virtual biopsy” for at-home use. The device uploads the captured image to an AI platform for analysis. It received FDA breakthrough device designation in 2022. At the ASLMS meeting, Dr. Witkowski said that clinical performance showed the device had a 97% sensitivity and 30% specificity for skin cancer.

DermaSensor, described in the study conducted by Dr. Hartman and others as a noninvasive, point-and-click spectrometer, is a wireless handheld piece that weighs about 10 ounces. The unit captures five recordings to generate a spectral reading, which an algorithm in the software unit analyzes. The study found a sensitivity of 95.5% and specificity of 32.5% for melanoma detection with the device.

The target market for DermaSensor is primary care physicians, and, according to the FDA announcement in January, it is indicated for evaluating skin lesions “suggestive” of melanoma, basal cell carcinoma (BCC), and/or squamous cell carcinoma (SCC) in patients aged 40 and older to “assist healthcare providers in determining whether to refer a patient to a dermatologist.”
 

So Many Cases, So Few Dermatologists

In dermatology, AI devices have the potential to streamline the crushing burden of diagnosing skin cancer, said Yun Liu, PhD, a senior staff scientist at Google Research, Mountain View, California, who’s worked on developing machine-learning tools in dermatology among other medical fields. “Many people cannot access dermatology expertise when they most need it, ie, without waiting a long time. This causes substantial morbidity for patients,” Dr. Liu said in an interview.

His own research of an AI-based tool to help primary care physicians and nurse practitioners in teledermatology practices diagnose skin conditions documented the shortage of dermatologists to triage lesions, including a finding that only about one quarter of skin conditions are seen by a specialist and that nonspecialists play a pivotal role in the management of skin lesions.

The Centers for Disease Control and Prevention reports that about 6.1 million adults are treated for BCC and SCCs each year. The American Medical Association estimates that 13,200 active dermatologists practice in the United States.
 

Overcoming Barriers to AI in Dermatology

Before AI makes significant inroads in dermatology, clinicians need to see more verifiable data, said Roxana Daneshjou, MD, PhD, assistant professor of biomedical data science and dermatology at Stanford University, Stanford, California. “One of the challenges is having the availability of models that actually improve clinical care because we have some very early prospective trials on different devices, but we don’t have large-scale randomized clinical trials of AI devices showing definitive behaviors such as improved patient outcomes, that it helps curb skin cancer, or it catches it like dermatologists but helps reduce the biopsy load,” she said. “You need good data.”

Another challenge she noted was overcoming biases built into medicine. “A lot of the image-based models are built on datasets depicting skin disease on White skin, and those models don’t work so well on people with brown and black skin, who have historically had worse outcomes and also have been underrepresented in dermatology,” said Dr. Daneshjou, an associate editor of NEJM AI.

There’s also the challenge of getting verified AI models into the clinic. “Similar to many medical AI endeavors, developing a proof-of-concept or research prototype is far easier and faster than bringing the development to real users,” Dr. Liu said. “In particular, it is important to conduct thorough validation studies on various patient populations and settings and understand how these AI tools can best fit into the workflow or patient journey.”

A study published in 2023 documented progress Google made in deploying AI models in retina specialty clinics in India and Thailand, Dr. Liu noted.

Another challenge is to avoid overdiagnosis with these new technologies, Dr. Hartman said. Her group’s study showed the DermaSensor had a positive predictive value of 16% and a negative predictive value of 98.5%. “I think there’s some question about how this will factor into overdiagnosis. Could this actually bombard dermatologists more if the positive predictive value’s only 16%?”

One key to dermatologists accepting AI tools is having a transparent process for validating them, Dr. Lee said. “Even with FDA clearance, we don’t have the transparency we need as clinicians, researchers, and advocates of machine learning and AI in healthcare.”

But, Dr. Lee noted, the FDA in June took a step toward illuminating its validation process when it adopted guiding principles for transparency for machine learning–enabled devices. “Once we can get more access to this information and have more transparency, that’s where we can think about actually about making the decision to implement or not implement into local healthcare settings,” she said. The process was further enabled by a White House executive order in October 2023 on the safe, secure, and trustworthy development and use of AI.

The experience with telehealth during the COVID-19 pandemic, when patients and providers quickly embraced the technology to stay connected, serves as a potential template for AI, Dr. Lee noted. “As we’d seen with telehealth through the pandemic, you also need the cultural evolution and the development of the infrastructure around it to actually make sure this is a sustainable implementation and a scalable implementation in healthcare.”

Dr. Lee had no relevant relationships to disclose. Dr. Hartman received funding from DermaSensor for a study. Dr. Witkowski is a cofounder of Sklip. Dr. Liu is an employee of Google Research. Dr. Daneshjou reported financial relationships with MD Algorithms, Revea, and L’Oreal.

Emerging diagnostic technology that uses artificial intelligence (AI) has demonstrated the potential to free dermatologists from the burden of triaging skin lesions, but dermatology lags behind some other specialties in harnessing the power of AI, and confusion surrounds dermatologists’ role in using this technology, according to researchers and dermatologists investigating AI.

While some AI-integrated devices designed to triage skin lesions have emerged, including one that received Food and Drug Administration (FDA) clearance earlier in 2024, it may be some time before AI has a meaningful clinical impact in dermatology and, more specifically, the diagnosis of skin cancer, Ivy Lee, MD, a dermatologist in Pasadena, California, and chair of the American Academy of Dermatology’s augmented intelligence committee, told this news organization.

CARLSBAD, CALIFORNIA — The level of training and supervision among individuals who perform cosmetic procedures at medical spas (MedSpas) varies widely, a trend that patients may not be aware of, according to Sara Hogan, MD.

Dr. Sara Hogan

The top five cosmetic procedures offered by the 127 surveyed MedSpas were facials (85.0%), hair removal (85.0%), botulinum toxin injections (83.5%), dermal fillers (82.7%), and chemical peels (76.4%). About two thirds of cosmetic procedures were performed by aestheticians (66.9%), followed by registered nurses or licensed practical nurses (52.8%), board-certified physicians (48.8%, mostly plastic and reconstructive surgeons), nurse practitioners (27.6%), and physician assistants (9.4%).

In the realm of supervision, 16.5% of MedSpas surveyed reported that a medical director or supervising physician is always on site. “If not located on site, when asked where the physicians are, the majority of the time they were at the physician’s primary practice, clinic, or hospital,” Dr. Hogan said. “Only 65% of the MedSpas surveyed stated that they informed the patient that the supervising physician is not on site. In addition, a patient’s medical history is reviewed at only 40% of the MedSpas. To give context, in Illinois, a physician can only deliver care after a physician-patient relationship has been established, meaning that a good faith exam has been performed. And if they are to delegate any type of service, they must always be on site to provide assistance.”

Dr. Hogan noted that there are no federal statutes or agencies that regulate or oversee MedSpas. “Regulation and oversight are often delegated to state licensing agencies that are overwhelmed and often stretched thin regarding personnel and budgets,” she said. To raise awareness of this issue, the American Society for Dermatologic Surgery Association (ASDSA) launched the Medical Spa Safety Coalition, which aims to promote model legislation for states known as the Medical Spa Safety Act. Highlights of the bill include clear definitions of medical spa and medical director, as well as the requirement of an on-site medical director who must be a physician trained in all procedures performed at the MedSpa. Coalition members include 16 state dermatology boards as well as the ASDSA, the American Academy of Dermatology Association, the American Society for Laser Medicine & Surgery, and the American Society of Plastic Surgeons.

The ASDSA provided funding to support the published study. Dr. Hogan reported having no financial disclosures.

Given the clinical presentation and the absence of other systemic or dermatological findings, the diagnosis of chevron nails was made.

Discussion

Chevron nails, also known as V-shaped nails or herringbone nails, are an uncommon but benign nail condition typically observed in infancy and early childhood. The condition is characterized by transverse ridges on the nails that converge towards the center, forming a V or chevron shape. This condition was first described by Perry et al. and later by Shuster et al., who explained that the condition might result from axial growth of the nail with synchronous growth occurring from a chevron-shaped growing edge of the nail root. Alternatively, Shuster suggested that sequential growth, with localized variation in the nail production rate, could propagate a wave from the center of the nail to the edge.

The etiology of chevron nails is not well understood, but it is believed to result from temporary disruptions in the nail matrix, possibly related to minor illness or physiological stress during infancy.

In the case of our 7-month-old patient, the history of mild upper respiratory infections might have contributed to the development of chevron nails. However, the lack of other significant illness, skin involvement, or systemic findings supports the benign and self-limiting nature of this condition. Parents were reassured that chevron nails typically resolve on their own as the child grows and that no specific treatment is necessary.
 

Differential Diagnosis

The differential diagnosis of transverse nail changes in children includes other conditions such as trachyonychia, lichen planus, Darier disease, and pachyonychia congenita.

Trachyonychia, also known as “sandpaper nails,” trachyonychia is characterized by the roughening of the nail surface, giving it a dull and ridged appearance. The condition may affect all 20 nails and is often associated with underlying dermatological conditions such as lichen planus or alopecia areata. Unlike chevron nails, trachyonychia presents with more diffuse nail changes and does not typically feature the distinct V-shaped ridging seen in this patient.

Lichen planus is an inflammatory condition that can affect the skin, mucous membranes, and nails. Nail involvement in lichen planus can lead to longitudinal ridging, thinning, and sometimes even complete nail loss. The absence of other characteristic features of lichen planus, such as violaceous papules on the skin or white lacy patterns on mucous membranes (Wickham striae), makes this diagnosis less likely in our patient.

Darier disease, also known as keratosis follicularis, is a genetic disorder characterized by greasy, warty papules primarily on seborrheic areas of the skin, nail abnormalities, and sometimes mucosal involvement. Nail changes in Darier disease include longitudinal red and white streaks, V-shaped notching at the free edge of the nails, and subungual hyperkeratosis. These nail changes are more severe and distinct than the simple transverse ridging seen in chevron nails. The absence of other clinical signs of Darier disease, such as skin papules or characteristic nail notching, makes this diagnosis unlikely in our patient.

Pachyonychia congenita is a rare genetic disorder characterized by thickened nails (pachyonychia), painful plantar keratoderma, and sometimes oral leukokeratosis. The condition typically presents with significant nail thickening and other systemic findings, which were absent in our patient. The distinct pattern of V-shaped ridging observed in chevron nails does not align with the typical presentation of pachyonychia congenita.
 

Next Steps

No specific treatment is required for chevron nails. The condition is typically self-resolving, and the nails usually return to a normal appearance as the child continues to grow. Parents were advised to monitor the nails for any changes or new symptoms and were reassured about the benign nature of the findings. Follow-up was scheduled to ensure the resolution of the condition as the child develops.

Conclusion

Chevron nails are an important consideration in the differential diagnosis of transverse nail ridging in infants and young children. While the condition is benign and self-limiting, it is crucial to differentiate it from other nail dystrophies, such as trachyonychia, lichen planus, Darier disease, and pachyonychia congenita, which may require further investigation or intervention. Awareness of chevron nails can help prevent unnecessary worry and provide reassurance to parents and caregivers.

Given the clinical presentation and the absence of other systemic or dermatological findings, the diagnosis of chevron nails was made.

Discussion

Chevron nails, also known as V-shaped nails or herringbone nails, are an uncommon but benign nail condition typically observed in infancy and early childhood. The condition is characterized by transverse ridges on the nails that converge towards the center, forming a V or chevron shape. This condition was first described by Perry et al. and later by Shuster et al., who explained that the condition might result from axial growth of the nail with synchronous growth occurring from a chevron-shaped growing edge of the nail root. Alternatively, Shuster suggested that sequential growth, with localized variation in the nail production rate, could propagate a wave from the center of the nail to the edge.

The etiology of chevron nails is not well understood, but it is believed to result from temporary disruptions in the nail matrix, possibly related to minor illness or physiological stress during infancy.

In the case of our 7-month-old patient, the history of mild upper respiratory infections might have contributed to the development of chevron nails. However, the lack of other significant illness, skin involvement, or systemic findings supports the benign and self-limiting nature of this condition. Parents were reassured that chevron nails typically resolve on their own as the child grows and that no specific treatment is necessary.
 

Differential Diagnosis

The differential diagnosis of transverse nail changes in children includes other conditions such as trachyonychia, lichen planus, Darier disease, and pachyonychia congenita.

Trachyonychia, also known as “sandpaper nails,” trachyonychia is characterized by the roughening of the nail surface, giving it a dull and ridged appearance. The condition may affect all 20 nails and is often associated with underlying dermatological conditions such as lichen planus or alopecia areata. Unlike chevron nails, trachyonychia presents with more diffuse nail changes and does not typically feature the distinct V-shaped ridging seen in this patient.

Lichen planus is an inflammatory condition that can affect the skin, mucous membranes, and nails. Nail involvement in lichen planus can lead to longitudinal ridging, thinning, and sometimes even complete nail loss. The absence of other characteristic features of lichen planus, such as violaceous papules on the skin or white lacy patterns on mucous membranes (Wickham striae), makes this diagnosis less likely in our patient.

Darier disease, also known as keratosis follicularis, is a genetic disorder characterized by greasy, warty papules primarily on seborrheic areas of the skin, nail abnormalities, and sometimes mucosal involvement. Nail changes in Darier disease include longitudinal red and white streaks, V-shaped notching at the free edge of the nails, and subungual hyperkeratosis. These nail changes are more severe and distinct than the simple transverse ridging seen in chevron nails. The absence of other clinical signs of Darier disease, such as skin papules or characteristic nail notching, makes this diagnosis unlikely in our patient.

Pachyonychia congenita is a rare genetic disorder characterized by thickened nails (pachyonychia), painful plantar keratoderma, and sometimes oral leukokeratosis. The condition typically presents with significant nail thickening and other systemic findings, which were absent in our patient. The distinct pattern of V-shaped ridging observed in chevron nails does not align with the typical presentation of pachyonychia congenita.
 

Next Steps

No specific treatment is required for chevron nails. The condition is typically self-resolving, and the nails usually return to a normal appearance as the child continues to grow. Parents were advised to monitor the nails for any changes or new symptoms and were reassured about the benign nature of the findings. Follow-up was scheduled to ensure the resolution of the condition as the child develops.

Conclusion

Chevron nails are an important consideration in the differential diagnosis of transverse nail ridging in infants and young children. While the condition is benign and self-limiting, it is crucial to differentiate it from other nail dystrophies, such as trachyonychia, lichen planus, Darier disease, and pachyonychia congenita, which may require further investigation or intervention. Awareness of chevron nails can help prevent unnecessary worry and provide reassurance to parents and caregivers.
