RESUMEN

BACKGROUND: Epidermolysis bullosa (EB), characterized by skin fragility and blistering, often requires hospitalization. Training for inpatient management of EB is limited, with no unified recommendations available in North America. OBJECTIVE: To develop consensus-derived best practices for hands-on inpatient management of EB in both the neonatal and postneonatal period. METHODS: A modified Delphi method (expert-based input via 2 surveys and a final review) was implemented. Available guidelines from EB Clinical Research Consortium centers were analyzed to determine areas of focus and formulate statements to be voted on by EB Clinical Research Consortium members, experienced EB nurses, and select family members. Study participants evaluated statements using a Likert scale: statements with at least 70% agreement were accepted; statements with 30% or more disagreement were rejected. RESULTS: Ten areas of focus were identified. Delphi participants included 15 dermatologists, 8 nurses, and 6 nonhealth care caregivers. Consensus was established on 103/119 neonatal statements and 105/122 postneonatal statements; no statements were rejected. Most recommendations applied to both age groups. LIMITATIONS: Recommendations may require adjustment based on individual patient's clinical context. CONCLUSION: Using the Delphi method, a consensus-derived resource for hospital-based health care professionals who manage patients with EB has been developed to improve the quality of inpatient care.

RESUMEN

BACKGROUND: In epidermolysis bullosa simplex (EBS), epithelial structural fragility results in blisters and erosions. Diacerein 1% ointment has been shown to reduce this blistering. OBJECTIVE: To evaluate the efficacy and safety of diacerein 1% ointment in the treatment of EBS. METHODS: A double-blind study of 54 patients with EBS were randomized to diacerein 1% or vehicle ointment once daily. The primary endpoint ( ≥60% reduction in body surface area of EBS) and the key secondary endpoint ( ≥2-point reduction in the Investigator’s Global Assessment) were evaluated at 8 weeks. RESULTS: There was no difference in the proportion of patients achieving either key efficacy endpoint between the diacerein 1% and vehicle groups (P>0.05). No difference in treatment emergent adverse events were noted between the groups. In post hoc analysis stratified by EBS subtypes, an IGA score of 0 or 1 was reported in 6 of 13 patients with severe EBS in the diacerein group (46.2%), compared with 2 of 13 patients with severe EBS in the vehicle group (15.4%); (relative risk= 3.08, 95% CI = 0.71, 13.4). CONCLUSIONS: Although there was no significant difference in outcomes between the groups, further study may elucidate the effects of diacerein on EBS lesions, especially in patients with severe EBS.

RESUMEN

Pediatric teledermatology rapidly expanded with the COVID-19 pandemic, and the impacts of this expansion on patients' access to care have not yet been entirely defined. In this retrospective study of 3027 patients in an academic pediatric dermatology practice, patients who identified as having a primary language other than English were less likely to access pediatric dermatology care during the COVID lockdown. This study did not identify a significant or meaningful difference in age, geography, socioeconomic status, ethnicity, or race between patients who were offered pediatric dermatology care that was either in-person or via synchronous telehealth. These findings are overall reassuring that there were not major disparities in telehealth utilization during the COVID shelter-in-place mandate, although highlight the need for institutions to ensure systems are in place to enhance telehealth access for patients with non-English primary language.

RESUMEN

The most common bacteria isolated from wound cultures in patients recorded in the Epidermolysis Bullosa Clinical Characterization and Outcomes Database (EBCCOD) are Staphylococcus aureus and Pseudomonas aeruginosa. Given the prevalence of P. aeruginosa in this patient population and prior research implicating P. aeruginosa's potential role in carcinogenesis, we sought to further analyze patients with recorded wound cultures positive for Pseudomonas aeruginosa in the EBCCOD. We provide a descriptive analysis of this subset of patients and highlight potential avenues for future longitudinal studies that may have significant implications in our wound care management for patients with epidermolysis bullosa.

RESUMEN

Background: Gene editing in induced pluripotent stem (iPS) cells has been hailed to enable new cell therapies for various monogenetic diseases including dystrophic epidermolysis bullosa (DEB). However, manufacturing, efficacy and safety roadblocks have limited the development of genetically corrected, autologous iPS cell-based therapies. Methods: We developed Dystrophic Epidermolysis Bullosa Cell Therapy (DEBCT), a new generation GMP-compatible (cGMP), reproducible, and scalable platform to produce autologous clinical-grade iPS cell-derived organotypic induced skin composite (iSC) grafts to treat incurable wounds of patients lacking type VII collagen (C7). DEBCT uses a combined high-efficiency reprogramming and CRISPR-based genetic correction single step to generate genome scar-free, COL7A1 corrected clonal iPS cells from primary patient fibroblasts. Validated iPS cells are converted into epidermal, dermal and melanocyte progenitors with a novel 2D organoid differentiation protocol, followed by CD49f enrichment and expansion to minimize maturation heterogeneity. iSC product characterization by single cell transcriptomics was followed by mouse xenografting for disease correcting activity at 1 month and toxicology analysis at 1-6 months. Culture-acquired mutations, potential CRISPR-off targets, and cancer-driver variants were evaluated by targeted and whole genome sequencing. Findings: iPS cell-derived iSC grafts were reproducibly generated from four recessive DEB patients with different pathogenic mutations. Organotypic iSC grafts onto immune-compromised mice developed into stable stratified skin with functional C7 restoration. Single cell transcriptomic characterization of iSCs revealed prominent holoclone stem cell signatures in keratinocytes and the recently described Gibbin-dependent signature in dermal fibroblasts. The latter correlated with enhanced graftability. Multiple orthogonal sequencing and subsequent computational approaches identified random and non-oncogenic mutations introduced by the manufacturing process. Toxicology revealed no detectable tumors after 3-6 months in DEBCT-treated mice. Interpretation: DEBCT successfully overcomes previous roadblocks and represents a robust, scalable, and safe cGMP manufacturing platform for production of a CRISPR-corrected autologous organotypic skin graft to heal DEB patient wounds.

RESUMEN

BACKGROUND: Anemia is a common complication of severe forms of epidermolysis bullosa (EB). To date, there are no guidelines outlining best clinical practices to manage anemia in the EB population. The objective of this manuscript is to present the first consensus guidelines for the diagnosis and management of anemia in EB. RESULTS: Due to the lack of high-quality evidence, a consensus methodology was followed. An initial survey exploring patient preferences, concerns and symptoms related to anemia was sent to EB patients and their family members. A second survey was distributed to EB experts and focused on screening, diagnosis, monitoring and management of anemia in the different types of EB. Information from these surveys was collated and used by the panel to generate 26 consensus statements. Consensus statements were sent to healthcare providers that care for EB patients through EB-Clinet. Statements that received more than 70% approval (completely agree/agree) were adopted. CONCLUSIONS: The end result was a series of 6 recommendations which include 20 statements that will help guide management of anemia in EB patients. In patients with moderate to severe forms of EB, the minimum desirable level of Hb is 100 g/L. Treatment should be individualized. Dietary measures should be offered as part of management of anemia in all EB patients, oral iron supplementation should be used for mild anemia; while iron infusion is reserved for moderate to severe anemia, if Hb levels of > 80-100 g/L (8-10 g/dL) and symptomatic; and transfusion should be administered if Hb is < 80 g/L (8 g/dL) in adults and < 60 g/L (6 g/dL) in children.

RESUMEN

BACKGROUND: Epidermolysis bullosa (EB) is a heterogeneous group of rare, difficult-to-treat, inherited multisystem diseases affecting epithelial integrity. Patients with EB are affected by mechanical fragility of epithelial surfaces including the skin and, as a result, extensive recurrent blistering is a characteristic of the condition. Chronic wounds predispose patients with EB to the development of squamous cell carcinoma, which is a major cause of premature death. OBJECTIVES: EASE was a double-blind, randomized, vehicle-controlled, phase III study to determine the efficacy and safety of the topical gel Oleogel-S10 (birch triterpenes) in EB. EASE was funded by Amryt Research Limited. METHODS: Patients with dystrophic EB, junctional EB or Kindler EB and a target partial-thickness wound lasting ≥ 21 days and < 9 months that was 10-50 cm2, were enrolled and randomized via computer-generated allocation tables 1 : 1 to Oleogel-S10 or control gel - both with standard-of-care dressings. Study gel was applied to all wounds at least every 4 days. The primary endpoint was the proportion of patients with first complete closure of target wound within 45 days. RESULTS: A total of 223 patients were enrolled and treated (109 treated with Oleogel-S10, 114 with control gel). The primary endpoint was met; Oleogel-S10 resulted in 41·3% of patients with first complete target wound closure within 45 days, compared with 28·9% in the control gel arm (relative risk 1·44, 95% confidence interval (CI) 1·01-2·05; P = 0·013). Adverse events (AEs) occurred with similar frequency for Oleogel-S10 (81·7%) compared with control gel (80·7%). AEs were predominantly of mild-to-moderate intensity (4·6% were severe). CONCLUSIONS: Oleogel-S10 is the first therapy to demonstrate accelerated wound healing in EB. Oleogel-S10 was well -tolerated.

RESUMEN

BACKGROUND/OBJECTIVES: The primary objective was to assess pain catastrophizing and functional disability in pediatric patients with epidermolysis bullosa (EB) and their parents/guardians. Secondary objectives included examining relationships between pain catastrophizing, functional disability, and correlations with other factors (e.g., age, disease severity, and percent of body surface area (BSA) involved). METHODS: Patients with EB ages 8-16 and their parents/guardians who were English or Spanish speaking completed a one-time online survey. Parent measures included: demographics questionnaire, Pain Catastrophizing Scale-Parent (PCS), and Parent Functional Disability Inventory (FDI). Child measures included: PCS child and child FDI. Higher scores on both scales indicate higher levels of catastrophizing and functional disability. RESULTS: Of 31 children, the mean age was 11.47 years and the majority (70.97%) had dystrophic EB. Mean scores were: 35.84 = PCS parent; 34.58 = PCS child; 30.87 = parent FDI; 29.77 = child FDI. Total scores for PCS parent, parent FDI, and child FDI increased significantly with disease severity and percentage of involved BSA (p < .01 for all). Total scores for PCS child increased significantly with percent of EB skin involvement (p = .04) but not disease severity. Older children reported more functional disability than their parents and younger children (p = .02). CONCLUSIONS: Our results demonstrate significant positive correlations between negative thoughts related to pain and the experience of functional difficulties in patients with EB and their caregivers. Psychological, psychiatric, and/or behavioral interventions to help managing chronic pain may be effective for patients with EB.

RESUMEN

BACKGROUND: Dystrophic epidermolysis bullosa (DEB) is a serious, ultra-rare, genetic blistering disease that requires a multidisciplinary care team and lifelong, proactive disease management. To organize and optimize care, we comprehensively examined diagnoses, healthcare use, and annual costs in patients with DEB across all healthcare settings. METHODS: A retrospective study was performed using electronic health record (EHR) data from Optum Clinical Database (January 1, 2016, through June 30, 2020). Patients with an epidermolysis bullosa (EB) diagnosis between July 1, 2016, and December 31, 2019, with ≥ 6 months of baseline and 12 months of follow-up activity were included. Patients were stratified by EB type: recessive DEB (RDEB), dominant DEB (DDEB), DEB (type unknown), and EB unspecified. Demographics, comorbid conditions, and healthcare resource utilization were identified from EHR data. Cost of bandages and total medical costs (US$) were identified from linked claims data. RESULTS: A total of 412 patients were included, classified as having DDEB (n = 17), RDEB (n = 85), DEB (type unknown; n = 45), and EB unspecified (n = 265). Mean age was 38.4 years, and 41.7% had commercial insurance coverage. The most common comorbidities were mental health disorders, malnutrition, and constipation. Rates of cutaneous squamous cell carcinoma ranged from 0% (DDEB) to 4.4% (RDEB). Prescriptions included antibiotics (56.6%), pain medications (48.3%), and itch medications (50.7%). On average, patients had 19.7 ambulatory visits during the 12-month follow-up, 22.8% had an emergency department visit, and 23.8% had an inpatient stay. Direct medical costs among patients with claims data (n = 92) ranged from $22,179 for EB unspecified to $48,419 for DEB (type unknown). CONCLUSIONS: This study demonstrated the range of comorbidities, multiple healthcare visits and prescription medications, and treatment costs during 1 year of follow-up for patients with DEB. The results underscore that the clinical and economic burden of DEB is substantial and primarily driven by supportive and palliative strategies to manage sequelae of this disease, highlighting the unmet need for treatments that instead directly address the underlying pathology of this disease.

RESUMEN

In 2013, Next Accreditation System and Milestones became the competency-based assessment framework required for all specialties accredited by the Accreditation Council for Graduate Medical Education. Dermatology residency programs implemented Milestones 1.0 in the 2013-2014 academic year. The Accreditation Council for Graduate Medical Education committed to review and revise Milestones 1.0 within 3 to 5 years. Subsequently, feedback from key stakeholders influenced the goals for revision, including reducing complexity, enhancing community engagement, and providing additional resources for programs. In 2019, the Dermatology Milestones 2.0 work group streamlined the specialty-specific patient care and medical knowledge subcompetencies. The harmonized milestones allowed for greater uniformity across specialties in systems-based practice, practice-based learning and improvement, professionalism, and interpersonal communication and skills. The work group developed a supplemental guide with specialty-specific context to help program directors, clinical competency committee members, and other faculty understand individual milestones. Dermatology Milestones 2.0 reduces the number of subcompetencies from 28 to 21. Milestones 2.0 represents an advancement in competency-based assessment for dermatology. The first year of reporting for Dermatology Milestones 2.0 is 2021.

RESUMEN

Importance: Pediatric alopecia areata (AA) prevalence and incidence data are key to understanding the natural history of this medical disease. Objective: To determine the prevalence and incidence of AA in a pediatric population across time, age, sex, race and ethnicity, and geographic areas within the US. Design, Setting, and Participants: In this multicenter cohort study conducted among 5 children's hospitals, data (January 2009 to November 2020) were collected from a standardized electronic health record (PEDSnet database, version 4.0) to evaluate the incidence and prevalence of pediatric AA. The study cohort included patients younger than 18 years with at least 2 physician visits during which a diagnosis code for AA was recorded, or 1 dermatologist specialty visit for which AA was recorded. Main Outcomes and Measures: The prevalence denominator population comprised 5 409 919 patients. The incidence denominator population was 2 896 241. We identified 5801 children for inclusion in the AA cohort, and 2398 (41.3%) had 12 months or more of follow-up and were included in the incidence analysis. Results: Of 5801 patients in the AA cohort, the mean (SD) age was 9.0 (4.5) years, 3259 (56.2%) were female, 359 (6.2) were Asian, 1094 (18.9%) were Black, 1348 (23.2%) were Hispanic, and 2362 (40.7%) were White. The overall prevalence of pediatric AA was 0.11%, and the participants in the AA cohort were more often older, female, and members of a racial and ethnic minority group than the full PEDSnet population. The 11-year overall incidence rate of pediatric AA between 2009 and 2020 was 13.6 cases per 100 000 person-years (95% CI, 13.1-14.2). The incidence rate by age was normally distributed and peaked at age 6 years. Rates were 22.8% higher in female patients than male patients (15.1 cases per 100 000 person-years for females vs 12.3 cases per 100 000 person-years for males). Additionally, incidence rates were highest among Hispanic children (31.5 cases per 100 000 person-years). Conclusions and Relevance: This cohort study examined the prevalence and incidence rates of pediatric AA in the US across time, age, sex, race and ethnicity, and region from 2009 to 2020, finding a prevalence of 0.11% (doubling during the last decade) and incidence rate of 13.6 cases per 100 000 person-years. Additionally, the results identified Asian and Hispanic children as high-risk demographic subgroups who were shown to be 2 and 3 times more likely, respectively, to receive a diagnosis of AA.

RESUMEN

Variants in RAS are known drivers of certain pediatric blood and solid cancers, including brain tumors. Though most RAS-driven cancers are thought to occur sporadically, genetic syndromes caused by germline RAS variants portend a slightly higher risk of rhabdomyosarcoma (RMS) development. Three new cases and a review of the literature demonstrate that in rare cases, certain somatic RAS variants are associated with an increased risk of RMS and that RMS development may be heralded by the presence of concomitant RAS-driven birthmarks. Further prospective studies are needed to establish incidence and recommend appropriate monitoring guidelines for patients at risk.

RESUMEN

BACKGROUND/OBJECTIVES: We evaluated the acceptance of synchronous (live video) telehealth for pediatric dermatology. METHODS: This was a prospective, single-center study of patient and dermatologist surveys paired at the encounter level for telehealth encounters with Children's Hospital Colorado Pediatric Dermatology Clinic between 21 April 2020 and 22 May 2020. RESULTS: Dermatologists were most receptive to a telehealth encounter for isotretinoin monitoring (96.6%) and non-isotretinoin acne (89.5%). In contrast, 71.8% and 58.8% of patients surveyed were open to telehealth for isotretinoin encounters and non-isotretinoin acne encounters, respectively. There was no significant correlation between patient and dermatologist satisfaction regarding a telehealth encounter (r = 0.09, CI [-0.09, 0.26], p = .34) or between patient and dermatologist preference for telehealth encounter (r = 0.07, CI [-0.11, 0.25] p = .46). Dermatologists reported needing a photo to aid their physical examination in 38/363 (10.7%) of encounters and preferred in-person examinations when an encounter would have benefitted from laboratories, procedures, dermatoscopic examination, examination by palpation, and accurate weights in infants. CONCLUSIONS: Synchronous, live-video telehealth is an effective method of healthcare delivery in certain situations for pediatric dermatology, but it does not replace in-person encounters. Families and dermatologists have different perceptions about its acceptance.

RESUMEN

IMPORTANCE: A comprehensive, user-friendly system to assess global ichthyosis disease burden is imperative to improving the care of patients with ichthyosis, identifying appropriate participants for clinical trials, and quantifying treatment outcomes. To our knowledge, there is currently no validated scale to objectively and systematically measure ichthyosis severity across the entire body. OBJECTIVE: To create and evaluate a comprehensive and user-friendly instrument to measure total body ichthyosis severity in adults and children. DESIGN, SETTING, PARTICIPANTS: In this qualitative study, ichthyosis experts participated in the content development of the Ichthyosis Scoring System (ISS). The body was divided into 10 regions, and Likert scales (0-4) were created to quantify scale and erythema, with extensive descriptors and photographic standards. An 83-image teaching set was created from photographs of participants with ichthyosis. Two cohorts of dermatologists (11 total) independently scored all test photographs twice to evaluate interrater and intrarater reliabilities. Participants were enrolled worldwide from referral centers and patient advocacy groups. Participants of all ages, races, and ethnicities were included in the creation of ISS, and dermatologists with varying experience and areas of expertise participated as raters to evaluate the ISS. The study was conducted from 2019 to 2021, and the data were analyzed in 2021. MAIN OUTCOMES AND MEASURES: Intraclass correlation coefficients determined overall reliabilities. RESULTS: Across both cohorts of 11 dermatologists in total, the intraclass correlation coefficients for total, scale and erythema scores were greater than 0.90 (95% CI, 0.77-0.97), greater than 0.91 (95% CI, 0.79-0.98), and greater than 0.88 (95% CI, 0.72-0.97), respectively. Most body sites exhibited moderate to good interrater reliabilities for scale and erythema. Intrarater reliabilities were good to excellent. CONCLUSIONS AND RELEVANCE: The results of this qualitative study demonstrate reproducibility and suggest that the ISS is a reliable system to measure global ichthyosis severity in adults and children.

RESUMEN

BACKGROUND: Accurate diagnosis of epidermolysis bullosa (EB) has significant implications for prognosis, management, and genetic counseling. OBJECTIVE: To describe diagnostic testing patterns and assess diagnostic concordance of transmission electron microscopy (TEM), immunofluorescence mapping (IFM), and genetic analysis for EB. METHODS: A retrospective cohort included patients enrolled in the Epidermolysis Bullosa Clinical Characterization and Outcomes Database from January 1, 2004, to July 8, 2019. Tests concluding the same EB type (EB simplex, junctional EB, dominant dystrophic EB, and recessive dystrophic EB) were considered concordant; those concluding different EB types were considered discordant; and those with nonspecific/nondefinitive results were equivocal. RESULTS: A total of 970 diagnostic tests were conducted from 1984 to 2018 in 771 patients. Genetic analyses were performed chronologically later than IFM or TEM (P < .001). The likelihood of undergoing genetic analysis was greater for junctional EB and recessive dystrophic EB, and the same for dominant dystrophic EB as compared with EB simplex. TEM results in 163 patients were equivocal (55%), concordant (42%), and discordant (3%). IFM results in 185 patients were equivocal (54%), concordant (42%), and discordant (4%). LIMITATIONS: Retrospective design. CONCLUSIONS: Diagnostic testing has shifted in favor of genetic analysis. TEM and IFM frequently offer equivocal findings when compared to the specificity afforded by genetic analysis.

RESUMEN

BACKGROUND: Epidermolysis bullosa (EB) is a group of rare epithelial disorders caused by abnormal or absent structural proteins at the epidermal-dermal junction. As a result, patients experience blisters and wounds from mild shearing forces. Some forms of EB are complicated by resultant scarring and contractures. The perioperative anesthetic management of patients with EB is complex and requires a systems-based approach to limit harm. We reviewed our experience with providing general anesthesia to patients at our tertiary EB referral center, including adverse events related to anesthetic care, outcomes in the immediate perioperative period, and details of anesthetic management. METHODS: We retrospectively reviewed the charts of all patients with EB anesthetized at the Children's Hospital Colorado between January 2011 and December 2016. A subset of pediatric anesthesiologists cared for all patients using a standardized clinical care pathway. Patient demographics, detailed anesthetic methods, immediate perioperative outcomes, and adverse events were characterized. RESULTS: Over a 6-year period, 37 patients underwent 202 general anesthetics. Most patients (75.7%) had dystrophic EB (DEB). Female patients comprised 48.6%. The majority (56.7%) traveled >50 miles to receive care, and many (35.1%) traveled >150 miles for their care. Common adaptations to care included avoidance of electrocardiogram leads (88.6%) and temperature probes (91.6%). Nasal fiberoptic intubation (n = 160) was performed, or natural airway/mask (n = 27) was maintained for most patients. Supraglottic devices were not used for airway management during any of the anesthetics. Anesthesia preparation time was longer (average 25.8 minutes [standard deviation {SD} = 12.7]) than our average institutional time (14 minutes). Succinylcholine was never used, and nondepolarizing muscle relaxants were used in only 1.5% of patient encounters. Blood was transfused in 16.3% of cases and iron infused in 24.8%. Average length of stay in the postanesthesia care unit was comparable to our institutional average (average 40.1 [SD = 28.6] vs 39 minutes). New skin or mucosal injury occurred in 8 encounters (4%), and desaturation occurred in 43 cases (21.3%). There were no major adverse events. CONCLUSIONS: By using a specialized team and a standardized clinical care pathway, our institution was able to minimize adverse events caused by the anesthetic and surgical care of patients with EB. We recommend natural airway or nasal fiberoptic airway management, meticulous avoidance of shear stress on the skin, and a multidisciplinary approach to care. Supportive therapy such as perioperative blood transfusions and iron infusions are feasible for the treatment of chronic anemia in this population.
