The characteristics of epidermolysis bullosa (EB) demand higher than average provider support for transition from pediatric to adult care. We administered an online Qualtrics survey to members of the Epidermolysis Bullosa Clinical Research Consortium (EBCRC), a group of providers who care for patients with EB, in order to examine their practices and perspectives on transition of care (TOC) and identify barriers to successful implementation. Sixteen of eighteen medical centers completed the survey. Eighty-eight percent of center representatives expressed concerns about their patients transitioning/transferring from the pediatric to adult-centered care. Thirty-eight percent of providers reported having a formal TOC program in place. Our findings support the desire for formal TOC programs, the need for a team-based approach and, in particular, identification of adult providers to participate in the transition to improve this often challenging time., (© 2024 Wiley Periodicals LLC.)

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., (© 2023 Wiley Periodicals LLC.)

There are little published data on the transition of care in EB. We conducted a survey study recruiting EB patients from the Dystrophic EB Research Association (debra) website and centers caring for high numbers of EB patients in the United States and internationally from Sept 17, 2019 to Nov 3, 2021. The majority of participants had not discussed the transition of care with their healthcare providers, nor the healthcare needs to be required as an adult. Ongoing pediatric subspecialty care was reported by 12% of adults, most commonly in pediatric dermatology. Identified barriers to transition included the perceived lack of adult providers' knowledge about EB patient healthcare needs. The results suggest the need for transition guidelines, early discussions with families about transition, and practical information for the adult providers accepting care., (© 2022 Wiley Periodicals LLC.)

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.

Background/objectives: Patients with epidermolysis bullosa (EB) require care of wounds that are colonized or infected with bacteria. A subset of EB patients are at risk for squamous cell carcinoma, and bacterial-host interactions have been considered in this risk. The EB Clinical Characterization and Outcomes Database serves as a repository of information from EB patients at multiple centers in the United States and Canada. Access to this resource enabled broad-scale analysis of wound cultures., Methods: A retrospective analysis of 739 wound cultures from 158 patients from 13 centers between 2001 and 2018., Results: Of 152 patients with a positive culture, Staphylococcus aureus (SA) was recovered from 131 patients (86%), Pseudomonas aeruginosa (PA) from 56 (37%), and Streptococcus pyogenes (GAS) from 34 (22%). Sixty-eight percent of patients had cultures positive for methicillin-sensitive SA, and 47%, methicillin-resistant SA (18 patients had cultures that grew both methicillin-susceptible and methicillin-resistant SA at different points in time). Of 15 patients with SA-positive cultures with recorded mupirocin susceptibility testing, 11 had mupirocin-susceptible SA and 6 patients mupirocin-resistant SA (2 patients grew both mupirocin-susceptible and mupirocin-resistant SA). SCC was reported in 23 patients in the entire database, of whom 10 had documented wound cultures positive for SA, PA, and Proteus species in 90%, 50%, and 20% of cases, respectively., Conclusions: SA and PA were the most commonly isolated bacteria from wounds. Methicillin resistance and mupirocin resistance were reported in 47% and 40% of patients tested, respectively, highlighting the importance of ongoing antimicrobial strategies to limit antibiotic resistance., (© 2020 Wiley Periodicals LLC.)

Background/objectives: Epidermolysis bullosa (EB) comprises a group of inherited skin blistering diseases. There is currently no cure, and management includes skin protection and prevention of infection. To date, there has been no systematic investigation of home skin care practices among EB patients on a multicenter scale., Methods: This cross-sectional, observational study included data collected from patients with EB enrolled in the Epidermolysis Bullosa Characterization and Clinical Outcomes Database (EBCCOD) who provided answers to a patient-directed questionnaire between January 1, 2017, and December 31, 2017., Results: Of 202 respondents, 130 (64.4%) had dystrophic EB, 51 (25.2%) had EB simplex, 21 (7.4%) had junctional EB, 3 (1.5%) had Kindler syndrome, and 3 (1.5%) had an unspecified subtype. Seventy-eight patients reported cleansing in plain water only (39%). Of those who used an additive in their cleansing water, 75 (57%) added salt, 71 (54%) added bleach, 36 (27%) added vinegar, and 34 (26%) endorsed the use of an "other" additive (multiple additives possible). Reported concentrations of additives ranged widely from 0.002% sodium hypochlorite and 0.002% acetic acid solutions, which are thought to have negligible effects on microbes, to 0.09% sodium hypochlorite and 0.156% acetic acid, concentrations shown to be cytotoxic. One hundred eighty-eight patients answered questions regarding topical product use (93%). Of those, 131 reported topical antimicrobial use (70%). Mupirocin and bacitracin were the most commonly reported topical antibiotics (59, 58 [31.4%, 30.9%], respectively)., Conclusions: These findings highlight the variety of skin care routines and frequent use of topical antimicrobials among EB patients and have potential implications for antibiotic resistance. The reported range of bleach and vinegar additives to cleansing water, including cytotoxic concentrations, emphasizes the need for clear and optimized skin cleansing recommendations., (© 2020 Wiley Periodicals, Inc.)

Importance: Children with epidermolysis bullosa (EB) comprise a rare population with high morbidity and mortality. An improved understanding of the clinical trajectory of patients with EB, including age at time of clinical diagnosis and major clinical events, is needed to refine best practices and improve quality of life and clinical outcomes for patients with EB., Objectives: To describe demographics, clinical characteristics, milestone diagnostic and clinical events (such as initial esophageal dilation), and outcomes in patients with EB using the Epidermolysis Bullosa Clinical Characterization and Outcomes Database and to determine what characteristics may be associated with overall EB severity and/or disease progression., Design, Setting, and Participants: This cohort study included data on patients with EB who were enrolled in the Epidermolysis Bullosa Clinical Characterization and Outcomes Database from January 1, 2011, to June 30, 2017; 17 participating EB centers in the United States and Canada contributed data to this study., Exposures: Type of EB, including recessive dystrophic epidermolysis bullosa (RDEB), junctional epidermolysis bullosa (JEB), dominant dystrophic epidermolysis bullosa (DDEB), and epidermolysis bullosa simplex (EBS)., Main Outcomes and Measures: Demographic information, clinical characteristics (including age at onset of signs of EB and subsequent clinical diagnosis), types of diagnostic testing performed, and milestone clinical events for patients with RDEB., Results: Of 644 enrolled patients from 17 sites included in this study, 323 were male (50.2%), with a mean (SD) age of 14.4 (11.7) years; 283 (43.9%) had RDEB, 194 (30.1%) had EBS, 104 (16.2%) had DDEB, and 63 (9.8%) had JEB. Signs of disease were present at birth in 202 patients with RDEB (71.4%), 39 with JEB (61.9%), 60 with DDEB (57.7%), and 74 with EBS (38.1%). For those with signs of disease at birth, a clinical diagnosis was made at the time of birth in 135 patients with RDEB (67.0%), 31 with DDEB (52.6%), 35 with EBS, (47.3%) and 18 with JEB (46.2%). Patients with JEB had the highest rate of any confirmatory testing (51 of 63 [81.0%]), followed by RDEB (218 of 283 [77.0%]), DDEB (71 of 104 [68.3%]), and EBS (100 of 194 [51.5%]). For all types of EB, both electron microscopy and immunofluorescence microscopy were performed at younger ages than genetic analysis. Among 283 patients with RDEB, 157 (55.5%) had esophageal dilation, 104 (36.7%) had gastrostomy tube placement, 62 (21.9%) had hand surgery, 18 (6.4%) developed squamous cell carcinoma, and 19 (6.7%) died., Conclusions and Relevance: The findings suggest that diagnostic testing for EB is more common for patients with severe phenotypes. Earlier diagnostic testing may enable improved characterizations of patients so that appropriate counseling and clinical care may be offered, especially pertaining to milestone events for those with RDEB.

Bullous diseases are uncommon in children; however, as they have the potential to affect quality of life, occasionally have long-term side effects in the setting of scarring processes, and carry a rare risk of underlying malignancy [e.g., with paraneoplastic pemphigus (PNP)], knowledge of their clinical presentation and treatment options is essential. Given the rarity of these conditions, our current state of knowledge is largely derived from case reports and case series, with a paucity of evidence-based recommendations. In this review, we discuss the clinical presentation of and treatment options for linear immunoglobulin A disease, dermatitis herpetiformis, pemphigus vulgaris, pemphigus foliaceus, PNP, bullous pemphigoid, mucus membrane pemphigoid, epidermolysis bullosa acquisita, and inherited epidermolysis bullosa. In general, when these conditions, except for PNP, occur in childhood, they have a better prognosis than when they occur in adults. Clinical, histopathological, and immunologic features frequently overlap, but distinct differences have also been reported, most commonly in clinical presentation. Treatment is often similar to that in adults, although specific considerations are necessary for a pediatric population. [ABSTRACT FROM AUTHOR]

A 3-year-old child with recessive dystrophic epidermolysis bullosa treated with bone marrow transplantation subsequently developed body-wide epidermal detachment distinct from his epidermolysis bullosa. Toxic epidermal necrolysis was diagnosed by examination and skin biopsy. Although graft-vs-host disease was considered, he had no features of this diagnosis by laboratory studies or skin biopsy, and he improved without addition of further immune suppressants. Throughout the episode, the patient was maintained on cyclosporine A, a component of his transplant regimen, and also a reported therapy for toxic epidermal necrolysis. He had full recovery. Re-epithelialization occurred in a unique folliculocentric pattern, which we postulate was related to the patient's mesenchymal stem cell infusion, received as an adjunct to his marrow transplantation.
