Following the initial presentation, the lesion was initially considered an acquired port wine stain and the child was referred for laser treatment. Upon reassessment during laser treatment a few months later, the lesion had progressed to hyper- and hypopigmented plaques with associated tissue sclerosis and bone atrophy on the mid forehead, nose, and scalp. Patches of alopecia and atrophy were observed on the frontal scalp. The diagnosis was revised to linear morphea en coup de sabre and the child was referred to pediatric rheumatology and commenced treatment with methotrexate and oral corticosteroids.

Linear morphea, a rare connective tissue disorder, primarily affects girls in the first 2 decades of life. Lesions can initially present in many ways. Usually, they present as hypo- or hyperpigmented patches, but may also present as lichenoid uncolored or pink plaques resembling lichen striatus. There may also be erythematous patches mimicking a capillary malformation, as seen in our patient. A recent article reviewing the progression of the lesions from erythematous patches to sclerosis suggests it occurs between 3 and 7 months of age. Subsequent stages manifest as significant atrophy, hypo- and hyperpigmentation, and in severe cases, bone atrophy and deformity, often causing substantial cosmetic disfigurement and functional impairment.

Pathophysiologically, linear morphea involves a complex interplay of immunologic, vascular, and fibrotic processes. While the initial triggers remain elusive, dysregulated immune responses leading to endothelial injury, subsequent activation of fibroblasts and myofibroblasts, and excessive collagen deposition are implicated. Angiogenic disturbances exacerbate tissue ischemia, perpetuating the fibrotic cascade. Alterations in cytokine signaling pathways, particularly TGF-beta and interleukin-6, play pivotal roles in promoting fibrosis and modulating the inflammatory milieu.

Diagnosis of linear morphea en coup de sabre relies on clinical examination, imaging (ultrasonography, MRI, CT scan), and skin biopsy for histopathological analysis. Imaging helps evaluate tissue involvement, while histology reveals characteristic dermal sclerosis, collagen deposition, and inflammation. Early-stage histology may show telangiectatic changes, complicating its differentiation from capillary malformation.

Treatment aims to mitigate symptoms, halt disease progression, and improve cosmesis and functionality. This involves a multidisciplinary approach with systemic medications, phototherapy, physical therapy, and surgical interventions in severe cases. Early identification is crucial for systemic treatments such as methotrexate and systemic corticosteroids to arrest disease progression. Other adjunctive therapies include topical corticosteroids, calcineurin inhibitors, and phototherapy. Surgical procedures like tissue expansion or autologous fat grafting may address tissue atrophy and deformities.

Linear morphea en coup de sabre presents diagnostic and therapeutic challenges because of its rarity and variable clinical course. Collaborative efforts among dermatologists, rheumatologists, radiologists, and surgeons are essential for accurate diagnosis, evaluation, and tailored management. Continued research into pathogenesis and novel therapeutic agents is pivotal to enhance understanding and improve outcomes for those affected by this enigmatic dermatologic condition.

SAN DIEGO — CD19-directed chimeric antigen receptor (CAR) T-cell therapy, which has transformed the treatment landscape for B-cell malignancies, is now showing great promise in at least three distinct autoantibody-dependent autoimmune diseases.

A single infusion of autologous CD19-directed CAR T-cell therapy led to persistent, drug-free remission in 15 patients with life-threatening systemic lupus erythematosus, idiopathic inflammatory myositis, or systemic sclerosis, according to research presented at the American Society of Hematology annual meeting.

The responses persisted at 15 months median follow-up, with all patients achieving complete remission, reported Fabian Mueller, MD, of the Bavarian Cancer Research Center and Friedrich-Alexander University of Erlangen-Nuremberg, Bavaria, Germany.

The CAR T-cell treatment appears to provide an “entire reset of B cells,” possibly even a cure, for these 15 patients who had run out of treatment options and had short life expectancies, Dr. Mueller said. “It’s impressive that we have treated these patients.”

Some of the cases have been described previously — including in Annals of the Rheumatic Diseases earlier this year, Nature Medicine in 2022, and the New England Journal of Medicine in 2021. 

Now with substantially longer follow-up, the investigators have gained a greater understanding of “the B-cell biology behind our treatment,” Dr. Mueller said. However, “we need longer follow-up to establish how effective the treatment is going to be in the long run.” 

All 15 patients included in the analysis were heavily pretreated and had multi-organ involvement. Prior to CAR T-cell therapy, patients had a median disease duration of 3 years, ranging from 1 to as many as 20 years, and had failed a median of five previous treatments. Patients were young — a median age of 36 years — which is much younger than most oncology patients who undergo CAR T-cell therapy, Dr. Mueller said. 

The 15 patients underwent typical lymphodepletion and were apheresed and treated with a single infusion of 1 x 10⁶ CD19 CAR T cells per kg of body weight — an established safe dose used in a phase 1 trial of B cell malignancies. 

The CAR T cells, manufactured in-house, expanded rapidly, peaking around day 9. B cells disappeared within 7 days and began to reoccur in peripheral blood in all patients between 60 and 180 days. However, no disease flares occurred, Dr. Mueller said.

After 3 months, eight patients with systemic lupus erythematosus showed no sign of disease activity and dramatic improvement in symptoms. Three patients with idiopathic inflammatory myositis experienced major improvements in symptoms and normalization of creatinine kinase levels, the most clinically relevant marker for muscle inflammation. And three of four patients with systemic sclerosis demonstrated major improvements in symptoms and no new disease activity. These responses lasted for a median of 15 months, and all patients stopped taking immunosuppressive drugs. 

Patients also tolerated the CAR T-cell treatment well, especially compared with the adverse event profile in oncology patients. Only low-grade inflammatory CAR T-related side effects occurred, and few patients required support for B-cell-derived immune deficiency. 

However, infectious complications occurred in 14 patients, including urinary tract and respiratory infections, over the 12-month follow-up. One patient was hospitalized for severe pneumonia a few weeks after CAR T therapy, and two patients experienced herpes zoster reactivations, including one at 6 months and one at 12 months following treatment. 

During a press briefing at the ASH conference, Dr. Mueller addressed the “critical question” of patient selection for CAR T-cell therapy, especially in light of the recently announced US Food and Drug Administration investigation exploring whether CAR T cells can cause secondary blood cancers. 

Although the T-cell malignancy risk complicates matters, CAR T cells appear to behave differently in patients with autoimmune diseases than those with cancer, he said.

“We don’t understand the biology” related to the malignancy risk yet, Dr. Mueller said, but the benefit for end-of-life patients with no other treatment option likely outweighs the risk. That risk-benefit assessment, however, is more uncertain for those with less severe autoimmune diseases.

For now, it’s important to conduct individual assessments and inform patients about the risk, Dr. Mueller said.

Dr. Mueller disclosed relationships with BMS, AstraZeneca, Gilead, Janssen, Miltenyi Biomedicine, Novartis, Incyte, Abbvie, Sobi, and BeiGene.

Treatment with bimekizumab significantly improved symptoms in adults with palmoplantar pustulosis (PPP) and palmoplantar plaque psoriasis with pustules, in a case series of 21 individuals.

PPP is a type of pustular psoriasis that remains a treatment challenge, and available treatments for palmoplantar plaque psoriasis with pustules also “remain unsatisfactory,” according to Thierry Passeron, MD, PhD, of the dermatology service at Centre Hospitalier Universitaire de Nice (France), and colleagues. Bimekizumab, an anti-interleukin (IL)-17A and anti-IL-17F antibody therapy, has been used for psoriasis and psoriatic arthritis (PsA), but its effectiveness for PPP has not been studied, they said. In the United States, bimekizumab (Bimzelx), administered subcutaneously, was recently approved for treating moderate to severe plaque psoriasis in adults; in the European Union, it is approved for treating psoriasis, in addition to psoriatic arthritis, axial spondyloarthritis and ankylosing spondylitis.

In the case series published in JAMA Dermatology, Dr. Passeron and coinvestigators identified 11 adults with PPP and 10 with palmoplantar plaque psoriasis with pustules who were treated at one of seven tertiary dermatology centers in France from September 2022 through June 2023. PPP also has been associated with bone and joint inflammation in SAPHO (synovitis, acne, pustulosis, hyperostosis, osteitis) syndrome.

All patients received bimekizumab for at least 3 months. The patients — 19 women and 2 men — ranged in age from 24 to 68 years (mean age, 46 years). The primary outcome was complete clearance, defined as an Investigator Global Assessment (IGA) score of 0.

A total of 17 patients achieved an IGA score of zero in 1-4 months. Over 3-6 months, three patients achieved an IGA score of 1 (almost clear), and one patient achieved an IGA score of 2 (mild).

Three patients with PPP also had acrodermatitis continua of Hallopeau; in these patients, nail involvement improved by 50%-70% after 4-6 months of bimekizumab use. Two patients with SAPHO experienced complete clearance of skin lesions associated with improvement in joint pain.

Four patients developed oral and genital candidiasis during treatment, but all were treated successfully with antifungals. None of the patients discontinued bimekizumab because of adverse events. “All patients are still receiving treatment, and their psoriatic lesions remain controlled,” the authors wrote.

“The rapid and consistent improvement observed in the present case series supports the effectiveness of bimekizumab therapy in managing PPP, palmoplantar plaque psoriasis with pustules, and SAPHO syndrome,” they said in their discussion.

The study findings were limited by several factors including the small sample size and short follow-up period, and by the inclusion of only patients with severe disease; and prospective, placebo-controlled studies are needed to confirm the results, the researchers noted.

However, the results suggest that bimekizumab could be a treatment approach for PPP, palmoplantar plaque psoriasis with pustules, and SAPHO syndrome, and warrant a prospective, randomized, placebo-controlled, randomized clinical trial to confirm the findings, they concluded.

Dr. Passeron disclosed fees from AbbVie, ACM Pharma, Almirall, Boehringer Ingelheim, Bristol Myers Squibb, Calypso, Celgene, Galderma, Genzyme/Sanofi, GlaxoSmithKline, Incyte, Janssen, LEO Pharma, Eli Lilly, Novartis, Roivant Sciences, Sun Pharmaceuticals, and VYNE Therapeutics outside the current study; he is a cofounder of Yukin Therapeutics. Three authors disclosed receiving personal fees from UCB, manufacturer of bimekizumab, outside of the submitted work, another author disclosed receiving personal fees from UCB during the conduct of the study, and another reported receiving grants from UCB and several other companies, outside the submitted work.

The study findings were also presented at a meeting, Les Journées Dermatologiques de Paris 2023, on December 6, in Paris.

Tape stripping, which allows sampling of the epidermis to the midgranular layer, is a valid, minimally invasive way to identify cutaneous biomarkers in patients with hidradenitis suppurative (HS), results from a novel study showed.

“Tape strips can provide important clues to when and which drugs to use in HS in patients with both early and late disease, which can change clinical practice,” corresponding study author Emma Guttman-Yassky, MD, PhD, professor and chair of dermatology at the Icahn School of Medicine at Mount Sinai in New York City, said in an interview. “It is noninvasive and nonscarring,” she added.

Tape stripping has been validated in atopic dermatitis, psoriasis, and other dermatologic conditions in recent years. For the current study, which was published online in the Journal of the American Academy of Dermatology, and is believed to be the first of its kind, Dr. Guttman-Yassky and colleagues performed RNA sequencing from large D-Squame tape strips collected from lesional and nonlesional skin of 22 patients with HS and from 21 age- and sex-matched healthy controls. They correlated the expression of skin biomarkers between tape strips and a previously published gene-signature of HS biopsies. The mean age of patients with HS was 43 years, while the mean age of healthy controls was 35. The average International Hidradenitis Suppurativa Severity Score System (IHS4) score of the HS cohort was 36.

Consistent with published studies, the researchers found that tape strips identified an overall higher inflammatory burden in HS. Specifically, they observed an upregulation of known cytokines within the following pathways: Th1 (such as IFNG, CXCL9/10/11, and CCR5); Th17 (such as interleukin [IL]-17A/F, IL12B, IL23A, CAMP, and CCL20); Th2 (such as IL4R, IL13/IL31/IL10, CCR4, CCL7/CCL13/CCL24, TNFSF4/OX40L, and TNFRSF4/OX40); and Th22 (such as IL22 and IL32).

The researchers also found that the expression of Th17 and tumor necrosis factor (TNF)–alpha pathways were highly correlated between tape strips and biopsies and that HS clinical severity was significantly associated with expression of biomarkers, such as TNF-alpha, IL17A/F, OX40, JAK1-3, and IL4R in HS lesional and/or nonlesional skin.

“It was quite unexpected that we are able to identify, using a minimally invasive approach that samples only the upper layers of the epidermis, products and processes that are considered to be deeper-situated, such as IL-17, and other immune markers,” Dr. Guttman-Yassky said in the interview. “We were also surprised to see how well the tape-stripped–derived skin molecular profile correlated with that of biopsies, as well as how well it correlated with the clinical disease severity of HS.”

Also surprising, she added, was that the biomarkers in nonlesional tape-stripped skin, such as IL-17 and TNF alpha, “show high correlations with disease severity and provide clues to early disease.”

If using tape strips in HS is validated in larger cohort studies, the potential cost implications of using this approach in practice remain unclear, Dr. Guttman-Yassky said. “It is currently not cheap, but we are hoping that one day, we can provide a means to diagnose the disease and treat it early, and appropriately, utilizing this approach,” she commented. “We are excited about the applicability of this study to the early treatment and longitudinal follow up of HS with drugs that are targeting specific immune molecules and pathways,” she said, adding that it will also be useful for helping determine which drug should be used for which patient.

She and her co-authors acknowledged certain limitations of the study, including its small sample size and the fact that tape stripping is limited to the epidermis.

Asked to comment on the study, Jennifer L. Hsiao, MD, a dermatologist who directs the HS clinic at the University of Southern California, Los Angeles, said the findings “have important potential implications for our ability to one day personalize treatments for a patient with early HS in a minimally invasive way.”

As the study authors point out, she added, “tape strips only allow sampling of the epidermis, which is limiting in a disease like HS where much of the disruption is in the dermis with deep nodules and dermal tunnels. However, our overall goal should be to catch patients in the early stages of their disease before the occurrence of irreversible tissue damage such as dermal tunnels. Thus, the ongoing campaign for early diagnosis and early intervention by various stakeholders in the field of HS can help mitigate the impact of this inherent limitation of tape strips. It will be exciting to see larger studies that investigate tape strip results in relation to clinical phenotypes, disease progression, and therapeutic responses.”

The study was funded by an International Dermatology Outcome Measures Hidradenitis Suppurativa Grant. Dr. Guttman-Yassky disclosed that she has been a consultant to, an adviser for, and has received research grants from many pharmaceutical companies. Of the remaining authors, 2 also had multiple disclosures and 11 had no disclosures. Dr. Hsiao disclosed that she is a member of the board of directors for the Hidradenitis Suppurativa Foundation. She has also served as a consultant for AbbVie, Aclaris, Boehringer Ingelheim, Incyte, Novartis, and UCB; as a speaker for AbbVie; and as an investigator for Amgen, Boehringer Ingelheim, and Incyte.

After years of declining vaccination coverage worldwide, measles deaths increased by 43% in 2022, compared with 2021. The number of total reported cases rose by 18% over the same period, accounting for approximately 9 million cases and 136,000 deaths globally, mostly among children. This information comes from a new report by the World Health Organization (WHO), published in partnership with the US Centers for Disease Control and Prevention (CDC).

More Measles Outbreaks

The report also notes an increase in the number of countries experiencing significant measles outbreaks. There were 37 such countries in 2022, compared with 22 the previous year. The most affected continents were Africa and Asia.

“The rise in measles outbreaks and deaths is impressive but, unfortunately, not surprising, given the decline in vaccination rates in recent years,” said John Vertefeuille, PhD, director of the CDC’s Global Immunization Division.

Vertefeuille emphasized that measles cases anywhere in the world pose a risk to “countries and communities where people are undervaccinated.” In recent years, several regions have fallen short of their immunization targets.

Vaccination Trends

In 2022, there was a slight increase in measles vaccination after a decline exacerbated by the COVID-19 pandemic and its impact on global healthcare systems. However, 33 million children did not receive at least one dose of the vaccine last year: 22 million missed the first dose, and 11 million missed the second.

For communities to be considered protected against outbreaks, immunization coverage with the full vaccine cycle should be at least 95%. The global coverage rate for the first dose was 83%, and for the second, it was 74%.

Nevertheless, immunization recovery has not reached the poorest countries, where the immunization rate stands at 66%. Brazil is among the top 10 countries where more children missed the first dose in 2022. These nations account for over half of the 22 million unadministered vaccines. According to the report, half a million children did not receive the vaccine in Brazil.

Measles in Brazil

Brazil’s results highlight setbacks in vaccination efforts. In 2016, the country was certified to have eliminated measles, but after experiencing outbreaks in 2018, the certification was lost in 2019. In 2018, Brazil confirmed 9325 cases. The situation worsened in 2019 with 20,901 diagnoses. Since then, numbers have been decreasing: 8100 in 2020, 676 in 2021, and 44 in 2022.

Last year, four Brazilian states reported confirmed virus cases: Rio de Janeiro, Pará, São Paulo, and Amapá. Ministry of Health data indicated no confirmed measles cases in Brazil as of June 15, 2023.

Vaccination in Brazil

Vaccination coverage in Brazil, which once reached 95%, has sharply declined in recent years. The rate of patients receiving the full immunization scheme was 59% in 2021.

Globally, although the COVID-19 pandemic affected measles vaccination, measures like social isolation and mask use potentially contributed to reducing measles cases. The incidence of the disease decreased in 2020 and 2021 but is now rising again.

“From 2021 to 2022, reported measles cases increased by 67% worldwide, and the number of countries experiencing large or disruptive outbreaks increased by 68%,” the report stated.

Because of these data, the WHO and the CDC urge increased efforts for vaccination, along with improvements in epidemiological surveillance systems, especially in developing nations. “Children everywhere have the right to be protected by the lifesaving measles vaccine, no matter where they live,” said Kate O’Brien, MD, director of immunization, vaccines, and biologicals at the WHO.

“Measles is called the virus of inequality for a good reason. It is the disease that will find and attack those who are not protected.”

Combined therapy with rituximab and omalizumab appears to be well tolerated, and improves outcomes and accelerates time to remission in patients with refractory bullous pemphigoid who do not respond to rituximab alone, results of a case series suggest.

Bullous pemphigoid (BP) is a rare, chronic, inflammatory, blistering disease that mainly occurs in people in their 50s through their 70s. BP has high morbidity and mortality, especially in people with comorbidities common to the elderly, yet no Food and Drug Administration–approved therapies for BP exist, Stephanie T. Le, MD, a dermatologist in the department of dermatology of the University of California, Davis, told this publication.

May Iosotaluno

All participants received 1000 mg intravenous rituximab on days 0 and 15. In addition to rituximab, seven patients received subcutaneous high-dose omalizumab (300 mg every 2 weeks); and three patients received low-dose omalizumab (300 mg every 4 weeks or 150 mg every 2 weeks).

After a mean of 2.1 months, all patients in the high-dose omalizumab-plus-rituximab group had achieved complete remission. By contrast, all patients in the low-dose omalizumab-plus-rituximab group improved after a mean of 13 months, and none achieved complete remission.

At 3 months, all study participants were rated as being very much improved. All four patients in the high-dose omalizumab group who tapered omalizumab dosage or frequency had flare-ups within 1-3 months that resolved when they restarted the medication. Among patients who achieved complete remission, 4 of 7 required rituximab redosing between 6 and 16 months later. Rituximab alone did not achieve remission: Three patients needed to add high-dose omalizumab. All reported adverse effects were mild.

Alternatives to Corticosteroids Are Needed

For BP, “with no FDA-approved therapies available, corticosteroids remain first line for acute flares. However, prolonged corticosteroid use is associated with multiple adverse effects, including increased susceptibility to infection, osteoporosis, and diabetes mellitus,” Dr. Le pointed out. “Patients with BP who are treated with high-dose corticosteroids have significantly increased mortality and have very poor 1-year survival.

“Rituximab and omalizumab dual therapy offers another potential treatment option for severe or treatment-refractory BP,” she added. “We are hopeful that other physicians will adopt this therapy.”

The authors acknowledged limitations of the study, including its retrospective design, small sample size, lack of standardized intervals between rituximab and omalizumab, and variation in concurrent therapies, and they recommended further related research.

No conflicts of interest were reported. No funding details were provided.

All participants received 1000 mg intravenous rituximab on days 0 and 15. In addition to rituximab, seven patients received subcutaneous high-dose omalizumab (300 mg every 2 weeks); and three patients received low-dose omalizumab (300 mg every 4 weeks or 150 mg every 2 weeks).

After a mean of 2.1 months, all patients in the high-dose omalizumab-plus-rituximab group had achieved complete remission. By contrast, all patients in the low-dose omalizumab-plus-rituximab group improved after a mean of 13 months, and none achieved complete remission.

At 3 months, all study participants were rated as being very much improved. All four patients in the high-dose omalizumab group who tapered omalizumab dosage or frequency had flare-ups within 1-3 months that resolved when they restarted the medication. Among patients who achieved complete remission, 4 of 7 required rituximab redosing between 6 and 16 months later. Rituximab alone did not achieve remission: Three patients needed to add high-dose omalizumab. All reported adverse effects were mild.

Alternatives to Corticosteroids Are Needed

For BP, “with no FDA-approved therapies available, corticosteroids remain first line for acute flares. However, prolonged corticosteroid use is associated with multiple adverse effects, including increased susceptibility to infection, osteoporosis, and diabetes mellitus,” Dr. Le pointed out. “Patients with BP who are treated with high-dose corticosteroids have significantly increased mortality and have very poor 1-year survival.

“Rituximab and omalizumab dual therapy offers another potential treatment option for severe or treatment-refractory BP,” she added. “We are hopeful that other physicians will adopt this therapy.”

The authors acknowledged limitations of the study, including its retrospective design, small sample size, lack of standardized intervals between rituximab and omalizumab, and variation in concurrent therapies, and they recommended further related research.

No conflicts of interest were reported. No funding details were provided.

Follicular occlusion, mast cell disease, and eczema were common presentations among patients with hypermobile Ehlers-Danlos syndrome (hEDS), in a study of nearly 500 individuals.

The genetic cause of hEDS, a common inherited connective tissue disorder, remains unknown, wrote Alan Snyder, MD, of the department of dermatology and dermatologic surgery at Medical University of South Carolina, Charleston, and colleagues.

Previous research suggests that changes in dermal mechanics predispose these patients to a range of skin conditions including mast cell activation disorder (MCAD) spectrum and chronic spontaneous urticaria, abnormal scars or wound healing, piezogenic papules, dyshidrosis, skin laxity or softness, easy bruising, local anesthesia resistance, keratosis pilaris, striae, and hidradenitis suppurativa, the researchers wrote.

However, data on these and other dermatologic manifestations of hEDS are limited, they said.

The diagnosis of hEDS will continue to be made more frequently and carefully, as the condition becomes more recognized and understood in the medical community, especially with anticipated capabilities of genetic testing, Dr. Snyder said in an interview.

“Being able to be aware of disease-specific comorbidities, such as those discovered in this study, allows providers to better stratify phenotypes and improve patient disease co-management,” he said.

In the study, published in the Journal of the American Academy of Dermatology, the researchers reviewed data on 1,364 patients with ICD-10 or ICD-9 codes for hEDS or EDS unspecified who were seen at a single institution between June 2005 and May 2022. Most of the patients were White (95.4%) and female (86.7%); the average age was 29.2 years.

Of the 1,364 patients included in the chart review, 497 (36.4%) had documented skin manifestations. Of these, 118 (24.2%) had disorders of follicular occlusion (12 had hidradenitis suppurativa, 32 had folliculitis, and 74 had acne); 112 (23%) had eczema or atopic dermatitis, 98 (19.7%) had mast cell disorder, 32 (6.4%) had psoriasis, and 32 (6.4%) had wound healing issues (16 had hypertrophic keloids/scarring, 5 had abscesses, 3 had abnormal bruising, and 8 had other would healing issues).

The study also included results of a multiple-choice patient survey from 1,354 individuals. In the survey, approximately two-thirds of patients reported abnormal scarring, abnormal wound healing, and cutaneous laxity (61.7%, 69.0%, and 71.0%, respectively).

The findings were limited by several factors including the retrospective study design, lack of testing to confirm hEDS diagnosis, and the potential interdisciplinary selection bias for diagnoses, the authors noted.

However, the results support previous studies showing increased rates of occlusive conditions in hEDS and higher rates of acne, folliculitis, and psoriasis, and highlight the need for clinician education to manage patients and promote better outcomes, the researchers concluded.

Data Enhance Clinical Awareness

“Given the increasingly understood relation between TH2-directed and mast-cell mediated diseases and hEDS, it was not necessarily a surprise to find the increased prevalence of atopy and mast cell disease, but rather an interesting confirmation, within the limitations that exist with retrospective chart review,” Dr. Snyder told this news organization. “While it may make some intuitive sense that certain cohorts with higher risk of HS may have a higher risk of acne, this had not been reported in the literature to date,” he noted. “Given the high levels of patient reported issues with scarring and wound healing, I was surprised that so few analogous diagnoses were physician-reported in the medical records.”

In clinical practice, “health care professionals and patients need to be aware hEDS is associated with high rates of eczematous, mast-cell mediated and follicular occlusive cutaneous disorders,” Dr. Snyder said in an interview. “There seems to be a discrepancy between patients and physician awareness of scarring or wound healing issues in this patient population,” he added.

Looking ahead, “we need to better research and characterize the various hEDS phenotypes to understand who is at highest risk for various TH2-mediated or follicular occlusive disorders,” said Dr. Snyder. “Moreover, a greater understanding is needed of the wound healing inadequacies that predispose these patients to poor outcomes during dermatologic surgery,” he said.

The study was supported by the Ehlers-Danlos Society and the Milton and Tamar Maltz Family Foundation. The researchers had no financial conflicts to disclose.

In a letter dated Nov. 30, 2023, the Food and Drug Administration informed isotretinoin manufacturers that they have 6 months to make five changes to existing iPLEDGE Risk Evaluation and Mitigation Strategy (REMS) requirements for the acne drug isotretinoin.

The development follows a March 2023 joint meeting of the FDA’s Drug Safety and Risk Management Advisory Committee and the Dermatologic and Ophthalmic Drugs Advisory Committee about iPLEDGE REMS requirements, which included feedback from patients and dermatologists and recommendations for changes to the REMS program, aimed at minimizing the burden of the program on patients, pharmacies, and prescribers while continuing to maintain safe use of the highly teratogenic drug for patients.

The five changes include the following:

• Remove the requirement that pregnancy tests must be performed in a specially certified (i.e., Clinical Laboratory Improvement Amendments [CLIA]) laboratory. In the opinion of John S. Barbieri, MD, MBA, director of the Advanced Acne Therapeutics Clinic at Brigham and Women’s Hospital, Boston, this change “may make it easier to perform pregnancy tests in a clinic setting without needing to send the patient to a separate lab,” he said in an interview.
• Allow prescribers the option of using home pregnancy testing for their patients during and after isotretinoin treatment. Prescribers who rely on the patient to perform a home pregnancy test need to take steps to minimize patients falsifying the results of these tests. According to Dr. Barbieri, this means that two pregnancy tests prior to starting isotretinoin must be done in a lab or office setting. “However, all the pregnancy tests on therapy can be either in a medical setting or using a home pregnancy test,” he told this news organization. “This option facilitates the use of telemedicine so that patients would not need to come in; they can just share a pregnancy test with their name and date with their dermatologist.”
• Remove the waiting period requirement — also known as the “19-day lockout” — for patients if they do not obtain isotretinoin within the first 7-day prescription window. According to Dr. Barbieri, this change helps to ensure that patients can begin isotretinoin in a timely manner. “Insurance and pharmacy delays that are no fault of the patient can commonly cause missed initial window periods,” he said. “Allowing for immediate repeat of a pregnancy test to start a new window period, rather than requiring the patient to wait 19 more days, can ensure patient safety and pregnancy prevention without negatively impacting access.”
• Revise the pregnancy registry requirement to remove the objective to document the pregnancy and fetal outcomes for each pregnancy.
• Revise the requirement for prescribers to document patient counseling in patients who cannot become pregnant from monthly to only at enrollment. Dr. Barbieri characterized this change as “major” and said that it could eliminate the need for monthly visits for persons of non–childbearing potential. “This could substantially reduce logistical burdens for patients and reduce wait times to see a dermatologist,” he said.

Future changes to iPLEDGE that Dr. Barbieri would like to see include allowing for home pregnancy tests prior to starting therapy — particularly the test after the 30-day window period. “In addition, it would be good to be able to reduce the 30-day waiting period prior to therapy to something shorter,” such as 14 days, which would still “reliably exclude pregnancy, particularly for those on stable long-acting reversible contraception,” he said. There are also opportunities to improve the iPLEDGE website functionality and to ensure that the website is accessible to patients with limited English proficiency, he added.

He also recommended greater transparency by the Isotretinoin Products Manufacturers Group and inclusion of input from diverse stakeholders such as dermatologists, patients, and pharmacists.

Much of my research focuses on what is known as clinical decision support — prompts and messages to providers to help them make good decisions for their patients. I know that these things can be annoying, which is exactly why I study them — to figure out which ones actually help.

When I got started on this about 10 years ago, we were learning a lot about how best to message providers about their patients. My team had developed a simple alert for acute kidney injury (AKI). We knew that providers often missed the diagnosis, so maybe letting them know would improve patient outcomes.

As we tested the alert, we got feedback, and I have kept an email from an ICU doctor from those early days. It read:

Dear Dr. Wilson: Thank you for the automated alert informing me that my patient had AKI. Regrettably, the alert fired about an hour after the patient had died. I feel that the information is less than actionable at this time.

Our early system had neglected to add a conditional flag ensuring that the patient was still alive at the time it sent the alert message. A small oversight, but one that had very large implications. Future studies would show that “false positive” alerts like this seriously degrade physician confidence in the system. And why wouldn’t they?

Knowing whether a patient is alive or dead seems like it should be trivial. But, as it turns out, in our modern balkanized health care system, it can be quite difficult. Not knowing the vital status of a patient can have major consequences.

Health systems send messages to their patients all the time: reminders of appointments, reminders for preventive care, reminders for vaccinations, and so on.

But what if the patient being reminded has died? It’s a waste of resources, of course, but more than that, it can be painful for their families and reflects poorly on the health care system. Of all the people who should know whether someone is alive or dead, shouldn’t their doctor be at the top of the list?

A new study in JAMA Internal Medicine quantifies this very phenomenon.

Researchers examined 11,658 primary care patients in their health system who met the criteria of being “seriously ill” and followed them for 2 years. During that period of time, 25% were recorded as deceased in the electronic health record. But 30.8% had died. That left 676 patients who had died, but were not known to have died, left in the system.
