RESUMEN
Our study aims to synthesize existing evidence of dupilumab for alopecia areata (AA) in pediatric patients with atopic dermatitis (AD). We searched MEDLINE and Embase on March 1, 2024, using keywords related to AD, AA, dupilumab, and pediatric patient populations per PRISMA-ScR guidelines. A mean SALT score reduction of 42.6 following dupilumab treatment (p < .01) over an average of 3.21 months, and a mean reduction of Investigator Global Assessment (IGA) levels of 2.14 units (p < .01) demonstrates the efficacy of dupilumab in pediatric AA when there is concurrent AD. Our findings in combination with dupilumab's favorable safety profile in pediatric AD makes it an appealing option for AA treatment, however, a greater understanding of the underlying mechanisms, optimal pediatric patient selection criteria, long-term efficacy, and safety profile of dupilumab in this context is warranted.
RESUMEN
INTRODUCTION: Bullous pemphigoid (BP) is the most common type of subepidermal blistering disease, usually observed in the elderly population, with a mean age of presentation between 66 and 83 years. BP is a psychosocially ladened disease, with many patients experiencing negative body image, social isolation, and depression. The identification and validation of biomarkers in BP may further the understanding of disease pathogenesis, provide objective measures in assessing efficacy in clinical trials, and identify new targets for targeted therapy. METHODS/RESULTS: Two databases (Medline and Embase) were searched from database inception to September 2023. All published articles reporting on biomarker levels of BP patients in serum compared to healthy controls were included. A total of 877 unique articles were identified, resulting in the inclusion of 62 case-control studies reporting on a total of 1837 patients and 140 unique biomarkers. Biomarkers were categorized into T-cell mediated, B-cell mediated, innate immune system, and coagulation cascade pathway. The most notable biomarkers identified include increases in anti-BP180/230 immunoglobulin (Ig)G/E, total IgE, TNF-α, B-cell activating factor, interleukin-31, eosinophil cationic protein, MMP-9, and coagulation cascade biomarker levels. The results of this review provide the greatest support for a role of anti-BP180/230 autoantibodies, Th2 cells, eosinophils, and the coagulation cascade in the pathogenesis of BP. CONCLUSIONS: The pathogenesis of BP has an underlying autoimmune etiology centred around the production of autoantibodies against BP180/230, but increased Th2, eosinophil and coagulation cascade activity may be contributory.
RESUMEN
INTRODUCTION: Pemphigus vulgaris (PV) is a rare intraepidermal blistering disease that is potentially life-threatening due to risk of infection and failure of skin barrier function. The identification of biomarkers has the potential to provide diagnostic utility and identify new therapeutic targets. The objective of this systematic review is to identify all potentially relevant PV biomarkers, categorize them, and identify trends to determine the involvement of T-cell-mediated, B-cell-1mediated, and innate immune-mediated pathways in PV pathogenesis. METHODS/RESULTS: Medline and Embase databases were searched according to Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines, resulting in the inclusion of 66 studies that reported on a total of 2463 patients and 146 unique biomarkers. Biomarkers were categorized into T-cell-mediated, B-cell-mediated, and innate immune system pathways. The most notable biomarkers trends include elevations in IL-4, IL-6, IL-17A, anti-Dsg1/3 autoantibodies, and a reduction in Treg cells and FOXP3. CONCLUSION: The results of this review support current theories of PV pathogenesis, with increased Th2 activity, increased Th17 activity, decreased Treg activity, and production of anti-Dsg1/3 autoantibodies being observed. Targeting of IL-4 and IL-6 may provide therapeutic benefit. However, more research is required to validate biomarkers for clinical utility and assess viability as therapeutic targets.
RESUMEN
Importance: Detecting activity of morphea can be complex but is crucial for adequate treatment and outcome assessment. The Morphea Activity Measure (MAM) was recently validated, but its responsiveness to change in disease activity has not been studied. Objective: To evaluate the internal and external responsiveness of MAM to changes in disease activity in pediatric patients. Design, Setting, and Participants: This multicenter prospective, longitudinal prognostic study was performed from October 2021 to January 2023 at 4 pediatric referral centers in North America. Consecutive pediatric patients with morphea who were available for data collection at baseline and at a follow-up visit at least 3 months later were studied. Exposure: Patient demographics, clinical characteristics, and measurements of disease activity collected at baseline and the subsequent visit. Main Outcome and Measures: Responsiveness of MAM to disease activity according to the modified Localized Scleroderma Severity Index (mLoSSI), the Physician Global Assessment (PGA), and a patient and parent global assessment (PtGA) was analyzed using mean and percentage change, standardized effect size, and standardized response mean (SRM) from baseline to follow-up 3 or more months later. Differences between patients whose activity improved vs did not improve were evaluated using the Mann-Whitney U test. The correlation between percentage change in MAM score and mLoSSI, the PGA, and the PtGA was calculated using Spearman rank correlation. Results: A total of 43 patients (mean [SD] age at onset, 7.11 [3.18] years; 26 [60.5%] female) were included. The mean change and percentage change in MAM score were significantly larger in those whose disease activity improved by the PGA (mean: -18.75 [95% CI, -31.92 to -5.57] vs 2.73 [95% CI, -1.97 to 7.45]; percentage: -108.08% [95% CI, -155.21% to -60.95%] vs -24.11% [95% CI, -81.22% to 32.99%]) and by mLoSSI (mean: -24.15 [95% CI, -41.89 to -6.41] vs -1.30 [95% CI, -8.50 to 5.70]; percentage: -172.06% [95% CI, -263.68% to -80.45%] vs -21.57% [95% CI, -48.13% to 4.97%]) than in those whose activity did not change. The SRM of MAM was significantly different between groups for both measures; the responsiveness was large in those whose activity decreased by the PGA (-0.75 [95% CI, -1.29 to -0.22]) and mLoSSI (-0.97 [95% CI, -1.69 to -0.25]) and none to small in those whose activity did not change by the PGA (0.11 [95% CI, -0.08 to 0.30]) or mLoSSI (-0.05 [95% CI, -0.34 to 0.23]). Percentage change in MAM score correlated strongly and significantly with change in mLoSSI (ρ = 0.69; P < .001) and PGA (ρ = 0.65; P < .001), but there was no correlation with change in the PtGA (ρ = 0.26; P = .09). Conclusions and Relevance: In this prognostic study, MAM was found to be internally and externally responsive to changes in disease activity. Further evaluation in mixed cohorts of all ages and specialties is needed.

Background: Atopic dermatitis (AD) is a chronic inflammatory skin disease resulting from the complex interplay of genetic and environmental factors, meriting exploration using temporally dynamic biomarkers. DNA methylation-based algorithms have been trained to accurately estimate biological age, and deviation of predicted age from true age (epigenetic age acceleration) has been implicated in several inflammatory diseases, including asthma. Objective: We sought to determine the role of epigenetic and biological aging, telomere length, and epigenetically inferred abundance of 7 inflammatory biomarkers in AD. Methods: We performed DNA methylation-based analyses in a pediatric AD cohort (n = 24, mean ± standard deviation [SD] age 2.56 ± 0.28 years) and age-matched healthy subjects (n = 24, age 2.09 [0.15] years) derived from blood using 5 validated algorithms that assess epigenetic age (Horvath, Skin&Blood) and biological age (PhenoAge, GrimAge), telomere length (TelomereLength), and inflammatory biomarker levels. Results: Epigenetic and biological age, but not telomere length, were accelerated in AD patients for 4 algorithms: Horvath (+0.88 years; 95% confidence interval [CI], 0.33 to 1.4; P = 2.3 × 10-3), Skin&Blood (+0.95 years; 95% CI, 0.67 to 1.2; P = 1.8 × 10-8), PhenoAge (+8.2 years; 95% CI, 3.4 to 13.0; P = 1.3 × 10-3), and GrimAge (+1.8 years 95% CI, 0.22 to 3.3; P = .026). Moreover, patients had increased levels of ß2 microglobulin (+47,584.4 ng/mL; P = .029), plasminogen activation inhibitor 1 (+3,432.9 ng/mL; P = 1.1 × 10-5), and cystatin C (+31,691 ng/mL; P = 4.0 × 10-5), while levels of tissue inhibitor metalloproteinase 1 (-370.7 ng/mL; P = 7.5 × 10-4) were decreased compared to healthy subjects. Conclusion: DNA methylation changes associated with epigenetic and biological aging, and inflammatory proteins appear early in life in pediatric AD and may be relevant clinical biomarkers of pathophysiology.
RESUMEN
Drug reaction with eosinophilia and systemic symptoms (DReSS) is known to cause mortality and long-term sequelae in the pediatric population, however there are no established clinical practice guidelines for the management of pediatric DReSS. We conducted a scoping review, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, to summarize the currently available data on treatment, mortality, and long-term sequelae of DReSS in children (aged 0-18 years). Data from 644 individuals revealed that various treatment strategies are being used in the management of pediatric DReSS, and strategies were often used in combination. The diversity in treatment approaches cannot be solely attributed to age or disease severity and reflects the lack of evidence-based management guidelines for DReSS. Children are also at risk of developing autoimmune sequelae following DReSS, most commonly thyroid disease and type 1 diabetes mellitus. We found that the eventual development of autoimmune disease was more often associated with DReSS caused by antibiotics, especially minocycline and sulfamethoxazole, in comparison with individuals who did not develop sequelae. In this study, we identify strengths and weaknesses in the currently available literature and highlight that future prospective studies with structured and long-term follow-up of children with DReSS are needed to better understand potential risk factors for mortality and development of sequelae after DReSS.

INTRODUCTION: Rosacea is a chronic inflammatory skin condition affecting approximately 5.5% of the global population. Patients present heterogeneously with a mix of features in the central facial region, of which papules and pustules are considered to be a major feature. The identification of effective treatments for reducing inflammatory lesions in rosacea can alleviate the psychosocial burden that many rosacea patients experience, including reduced self-esteem, anxiety, and social withdrawal. The objective of this systematic review is to determine the effectiveness of topical and systemic therapies in reducing lesion count in rosacea patients. METHODS/RESULTS: Medline, Embase, and Cochrane CENTRAL databases were searched, resulting in the inclusion of 43 clinical trials reporting on a total of 18,347 rosacea patients. The most well-studied treatments include ivermectin, metronidazole, azelaic acid, minocycline, and doxycycline. Oral isotretinoin was the most effective treatment in reducing inflammatory lesions and may be recommended for severe recalcitrant cases of rosacea. CONCLUSIONS: Several topical and systemic therapies have demonstrated efficacy in reducing inflammatory lesion count in rosacea patients, with mechanisms of action centred around suppressing inflammation and killing Demodex folliculorum mites. Additional research is required to determine effective combination therapies in rosacea.
RESUMEN
Effective treatment of drug reactions with eosinophilia and systemic symptoms (DReSS) requires early diagnosis and close monitoring. Diagnosing DReSS is especially challenging in children due to a low incidence rate, heterogeneous clinical presentation, and a lack of (pediatric) diagnostic criteria and clinical practice guidelines. We performed a scoping review, according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, to summarize the clinical presentation and diagnostic process of DReSS in children (aged 0-18 years). Data from 644 individuals showed that DReSS manifests differently in children compared to adults. Children have a higher number of organs involved, including higher rates of cardiac and respiratory involvement compared to adults. Children < 6 years of age appear more prone to develop neurologic symptoms. Conversely, eosinophilia, edema, and kidney involvement are less frequently observed in children. Anti-seizure medications are by far the most common causative drug class, but the range of implicated drugs increases as children get older. This study highlights that children with DReSS not only differ from adults but also that differences exist between children of different ages. As such, there is a need to establish pediatric-specific diagnostic criteria. These efforts will promote earlier diagnosis of DReSS and likely lead to improved clinical care offered to children and their families.

BACKGROUND: Dupilumab is approved for moderate-severe atopic dermatitis (AD) in patients aged ≥6 months by the US Food and Drug Administration and Health Canada; however, there are little real-world data because providers have limited practical experience with this recently approved therapy. OBJECTIVES: To describe the real-world effectiveness and safety in patients aged <12 years with moderate-severe AD currently receiving or previously having received dupilumab. METHODS: A multicenter retrospective study was conducted at six Canadian sites. Cases were divided into Group 1 ≤2 years old, Group 2 >2 to <6 years old, and Group 3 ≥6 to <12 years old. Medical history and details of dupilumab treatment were collected. The primary outcome was to measure the improvement in eczema area and severity index. Secondary outcomes examined included the children's dermatology life quality index/infant's dermatitis quality of life, peak pruritus numerical rating scale, and delay to dupilumab access for patients who were considered off-label for dupilumab due to their age. RESULTS: Sixty three pediatric patients (37 males) with moderate-to-severe AD were included; the mean age was 6.4 years old (range: 2-11) when dupilumab treatment was started. Overall, 75% (36/48) achieved EASI-75% and 71% (34/48) achieved EASI-90. EASI-75 and EASI-90 were achieved in 90% (17/19) and 73% (12/19) in patients <6 years old, and 76% (22/29) and 59% (17/29) in patients >6 years old, respectively. No serious adverse events were reported. CONCLUSIONS: Dupilumab is safe and effective for patients under the age of 12. However, even for experienced providers, access to the medication was challenging.

OBJECTIVE: The prevalence and types of psychosocial complications of juvenile localized scleroderma (JLS), also known as morphea, an inflammatory and sclerosing disease involving the skin, fascia, muscle, and bone, are poorly understood. METHODS: We performed a systematic review of literature published between 2000 and 2020 in PubMed, EMBASE, the Cochrane Skin Group Specialized Register, the Cochrane Central Register of Controlled Trials, and the Cumulative Index to Nursing and Allied Health Literature using the search terms "scleroderma, localized," "Morphea," "anxiety," "depression," "resilience," "social stigma," "quality of life," "mood," or "stress" and limited the search to pediatric patients and English language. Patient demographics, characteristics of JLS, and comorbidities were extracted. The outcomes included measures of health-related quality of life (HRQoL), psychosocial functioning, evaluation of self-perception, and the treatment burden of the study population. The protocol was registered with PROSPERO (CRD42021257124). Thematic synthesis generated descriptive analysis. RESULTS: Thirteen studies fulfilled the inclusion criteria: three retrospective cohort studies, two prospective cohort studies, and eight cross-sectional studies. A total of 690 pediatric patients with JLS were included (n = 484 with linear scleroderma). Six studies used the Children's Dermatology Life Quality Index, reporting little to no effect on HRQoL. One study used the Health-Related Quality of Life in Children and Adolescents Questionnaire and did not find differences between children with JLS or atopic dermatitis and healthy controls. One study used a self-perception questionnaire that showed normal self-worth of patients with JLS. Two studies used focus groups, both reporting elevated levels of stress, decreased self-worth, "feeling different," and bullying/teasing in patients with JLS. These emotions were associated with skin symptoms (pain, itch, and tightness), physical limitations, and treatment burden. CONCLUSION: Overall, quantitative studies did not report a statistically significant impairment in HRQoL in JLS. However, qualitative studies (focus groups) reported significant psychosocial impacts related to JLS. There is a need to develop a JLS-specific tool for the HRQoL evaluation of this population.

BACKGROUND: There is a well-documented risk of secondary cutaneous malignancies following allogeneic hematopoietic stem cell transplant (HSCT), but data on risk in pediatric populations are limited. The objective of this study is to perform a systematic review of reported features and outcomes of skin cancers in pediatric allogeneic HSCT recipients. METHODS: MEDLINE, EMBASE, CINAHL, Cochrane, and Web of Science were systematically searched (Prospero CRD42022342139). Studies reporting cutaneous cancer outcomes were included if the age at transplant was ≤19 years. Titles, abstracts, and full-text articles were screened in duplicate. RESULTS: Out of 824 citations that were screened, 12 articles were selected for analysis. The final sample included 67 pediatric HSCT recipients, comprising 65 allogeneic transplant recipients and 2 cases of HSCT with an unknown donor type. The median age at transplant and skin cancer diagnosis were 7.4 and 13 years, respectively. Out of the 67 pediatric HSCT recipients, some patients developed more than one lesion, resulting in 71 lesions. The most common skin cancer type was cutaneous squamous cell carcinoma (32 lesions), followed by basal cell carcinoma (25 lesions). The median latency period between HSCT and skin cancer diagnosis ranged from 0 to 29 years. Identified risk factors for skin cancers included younger age at the time of transplant, exposure to total body irradiation, prolonged post-transplant immunosuppression, graft versus host disease, and sunburn. CONCLUSION: Skin cancers are reported in pediatric allogeneic HSCT recipients, and the risk appears to be increased. More data are needed to better characterize this risk.

BACKGROUND/OBJECTIVE: Stiff skin syndrome (SSS) is a rare disorder characterized by "rock hard" indurated skin affecting different body parts. The localized variant poses a diagnostic challenge, as it is frequently mistaken for other inflammatory connective tissue disorders. The aim of this study is to provide insightful clinical, radiologic and diagnostic data that might prove useful for the evaluation, management and treatment of pediatric patients with segmental SS. METHODS: This single-center cohort study included patients ≤18 years diagnosed with localized SSS from 1988 to 2021 in a quaternary pediatric healthcare center in Toronto, Canada. Data included demographics, clinical, histopathologic and radiologic features, treatments, and clinical course. Data were summarized with descriptive statistics (mean, standard deviation, medians, interquartile ranges [IQRs]) and frequencies. RESULTS: A total of 11 patients were included. The sclerotic changes were measured clinically and radiologically, by a total of 16 imaging studies: 13 magnetic resonance imaging (MRI) and 3 ultrasound. MRI readings showed abnormal high signal intensity of the affected tissue correlating with the anatomical site of involvement in all cases, specifically, in the shoulder/pelvic girdle with limb extension. Shear wave ultrasound elastography (SWE) demonstrated higher values within the dermis compared to the control site. CONCLUSION: The presence of segmental sclerotic changes that affects the pelvic/shoulder girdle with extension to the extremities, in the absence of inflammation on biopsy and abnormal signaling intensity on imaging is suggestive of SSS. Skin SWE is a feasible, noninvasive, and objective instrument to evaluate and monitor sclerotic changes overtime, it could be potentially extrapolated to other pediatric skin sclerotic conditions.

At present, there are no standardized guidelines for determining patient eligibility for pyoderma gangrenosum (PG) clinical trials. Thus, we aim to determine which clinical features, histopathological features, or laboratory features should be included in active ulcerative PG clinical trial eligibility criteria for treatment-naïve patients and patients already treated with immunomodulating medications (treatment-exposed patients). This study employed 4 rounds of the Delphi technique. Electronic surveys were administered to 21 international board-certified dermatologists and plastic surgeon PG experts (June 2022-December 2022). Our results demonstrated that for a patient to be eligible for a PG trial, they must meet the following criteria: (i) presence of ulcer(s) with erythematous/violaceous undermining wound borders, (ii) presence of a painful or tender ulcer, (iii) history/presence of rapidly progressing disease, (iv) exclusion of infection and other causes of cutaneous ulceration, (v) biopsy for H&E staining, and (vi) a presence/history of pathergy. These criteria vary in importance for treatment-naïve versus treatment-exposed patients. Given the international cohort, we were unable to facilitate live discussions between rounds. This Delphi consensus study provides a set of specific, standardized eligibility criteria for PG clinical trials, thus addressing one of the main issues hampering progress toward Food and Drug Administration approval of medications for PG.

OBJECTIVE: Methotrexate is an immunosuppressant commonly used in dermatology. The prevalence of intolerance using the Methotrexate Intolerance Severity Score (MISS) in pediatric juvenile idiopathic arthritis (JIA) ranges from 25% to 75%, but studies in morphea patients are lacking. We sought to determine the prevalence and predictors of methotrexate intolerance in children with morphea compared with children with inflammatory skin diseases and JIA/uveitis. METHODS: Eligible patients were ages 2 to 18 years and were taking methotrexate for at least 3 months to treat morphea, inflammatory skin disease, or uveitis/JIA. Methotrexate intolerance was calculated using the MISS. A 1-way analysis of variance compared absolute intolerance scores. Multivariate regression analysis was used to compare MISS across diseases and covariates. RESULTS: Of 48 participants (mean ± SD age, 11.3 ± 4.1 years, 70.8% female), 15 had morphea, 16 had JIA/uveitis, and 17 had inflammatory skin diseases. The overall prevalence of intolerance was 20.8%. Age, sex, duration, and dose did not correlate with overall MISS. The MISS mean ± SD total for oral dosing was 2.5 ± 3.4, compared with 6.78 ± 6.8 for subcutaneous dosing. Patients with JIA/uveitis had the highest prevalence of intolerance (37.5%, n = 6), followed by morphea patients (20%, n = 3) and inflammatory skin disease patients (5.9%, n = 1). The OR of intolerance according to route of administration was 11.2 (95% CI, 2.03-61.89). CONCLUSIONS: Methotrexate intolerance was highest among patients with JIA/uveitis. The only predictor for risk of intolerance was subcutaneous route of administration. Future work could examine disease activity correlations and interventions designed to minimize intolerance.
RESUMEN
Hidradenitis suppurativa (HS) is a chronic, recurrent, inflammatory skin condition that manifests as painful, deep-seated, inflamed nodules and abscesses in the axillary, groin, perianal, perineal, and inframammary regions. The associated pain, malodour, and disfigurement contribute to its profound negative impact on psychosocial spheres and overall quality of life in affected individuals. Although the symptoms of HS classically begin in the second or third decade of life, HS affects children and adolescents as well. Despite this, there are limited pediatric data on treatment, which are largely based on expert opinion, extrapolation of efficacy data in adults with HS, and safety information from medication use in other pediatric diseases. On this basis, there exist several pharmacological modalities in the treatment of children and adolescents with HS including topical therapies, systemic therapies, and biologics. The goals of this review article are to: (1) review the efficacy of different pharmacological treatment modalities in children and adolescents with HS, and (2) review the safety and monitoring considerations of the different treatment options in children and adolescents with HS.

INTRODUCTION: The need for pediatric dermatology services is increasing across Canada. In parallel, the complexity of treatment with novel targeted therapeutics has increased. Currently, there is no accredited and limited non-accredited fellowship training access to pediatric dermatology in Canada. HYPOTHESIS: Understanding the current state of pediatric dermatology training in Canada will provide insight into opportunities for strategic improvement. METHODS: A survey was distributed to 44 pediatric dermatology providers. In addition, a review of the burden of pediatric skin disease and education/training in Canada was performed. RESULTS: Thirty-four specialists responded to the survey (77% response rate). One third of current pediatric dermatology providers are over 50 years old and half of these (15%) plan to retire within the next 5 years. Half of respondents were dermatologists, 35% were pediatricians, and 11% were double boarded. Almost all respondents practiced in an academic setting (94%). Most had further fellowship training in pediatric dermatology (82.4%) but only 57% achieved this training in Canada, due to lack of accredited or non-accredited funded fellowship positions. CONCLUSION: There is a high and growing need for pediatric dermatology specialty care in a diverse range of settings. The current provider population and training programs are insufficient to meet current and future demands. We highlighted solutions to close this gap between supply and demand including increased double board certification in Pediatrics and Dermatology, a protected pediatric stream within existing Dermatology residency training programs and accredited fellowships in Pediatric Dermatology for both dermatologists and pediatricians.
