Abstract
ABSTRACT Junctional epidermolysis bullosa (JEB) is a rare, incurable, devastating, and mostly fatal congenital genetic disorder characterized by painful blistering of the skin and mucous membranes in response to minor trauma or pressure. JEB is classified roughly into 2 subtypes: JEB-Herlitz is caused by mutations on genes encoding laminin-332. The authors present a patient consulted with a suspicion of primary immunodeficiency due to skin sores that started at the age of 1 month and a history of 3 siblings who died with similar sores, who was diagnosed with JEB-Herlitz after detecting a homozygous LAMC2 gene mutation in WES analysis. Microscopic evaluation of hematoxylin and eosin-stained sections showed vesicle formation with subepidermal separation, which is accompanied by striking neutrophil and eosinophil leukocyte infiltration both in the vesicle and papillary dermis (eosinophil-rich inflammatory infiltrate). Such a histopathological finding has been rarely reported in this condition.

[PMID: 38949448 PMCID: PMC11219618 DOI: 10.4102/safp.v66i1.5897] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2024] [Revised: 04/24/2024] [Accepted: 04/25/2024] [Indexed: 07/02/2024] Open
Abstract
BACKGROUND Epidermolysis bullosa (EB) is a rare, incurable genodermatosis that presents with blistering and skin fragility. Complications can be localised or generalised, limited to the skin or have systemic effects resulting in death. Caring for a child with this painful condition can have a profound effect on the quality of life of parents and the family. There is currently no published research on the lived experience of parents caring for a child with EB in a resource-limited environment in Africa. METHOD This qualitative research used interpretative phenomenological analysis with the aim of understanding the lived experiences of parents caring for children with EB. Semi-structured interviews were conducted with 13 participants between May 2022 and October 2023. Guba's framework of trustworthiness was used to ensure rigour. RESULTS Seven experiential themes with associated sub-themes were identified. The themes were (1) grappling with understanding EB, (2) the psychological experience, (3) living with the responsibility, (4) barriers to feeling supported, (5) changing relational dynamics, (6) experience of healthcare professionals and (7) parental needs. CONCLUSION Parents caring for children with EB face emotional, physical, psychosocial and financial challenges. Addressing parents' needs and concerns will go a long way in decreasing this burden. A biopsychosocial approach with an awareness of cultural context is essential for family-centred holistic EB care.Contribution: This is the first study in Africa that focussed on the lived experiences of parents caring for a child with EB.

Abstract
BACKGROUND Genotype-phenotype associations in recessive dystrophic epidermolysis bullosa (RDEB) have been difficult to elucidate. OBJECTIVE To investigate RDEB genotype-phenotype associations and explore a functional approach to genotype classification. METHODS Clinical examination and genetic testing of RDEB subjects, including assessment of clinical disease by RDEB subtype and extent of blistering. Genotypes were evaluated according to each variant's effect on type VII collagen function per updated literature and subsequently categorized by degree of impact on VII collagen function as low-impact (splice/missense, missense/missense), medium-impact (premature termination codon [PTC]/missense, splice/splice), and high-impact (PTC/PTC, PTC/splice). Genotype-phenotype associations were investigated using Kruskal-Wallis and Fisher's exact tests, and age-adjusted regressions. RESULTS Eighty-three participants were included. High-impact variants were associated with worse RDEB subtype and clinical disease, including increased prevalence of generalized blistering (55.6% for low-impact vs 72.7% medium-impact vs 90.4% high-impact variants, P = .002). In age-adjusted regressions, participants with high-impact variants had 40.8-fold greater odds of squamous cell carcinoma compared to low-impact variants (P = .02), and 5.7-fold greater odds of death compared to medium-impact variants (P = .05). LIMITATIONS Cross-sectional design. CONCLUSION Functional genotype categories may stratify RDEB severity; high-impact variants correlated with worse clinical outcomes. Further validation in larger cohorts is needed.

Abstract
Epidermolysis bullosa (EB) is an umbrella term for a group of rare inherited skin disorders characterised by mucocutaneous fragility. Patients suffer from blisters and chronic wounds that arise spontaneously or following minor mechanical trauma, often resulting in inflammation, scarring and fibrosis due to poor healing. The recessive form of dystrophic EB (RDEB) has a particularly severe phenotype and is caused by mutations in the COL7A1 gene, encoding the collagen VII protein, which is responsible for adhering the epidermis and dermis together. One of the most feared and devastating complications of RDEB is the development of an aggressive form of cutaneous squamous cell carcinoma (cSCC), which is the main cause of mortality in this patient group. However, pathological drivers behind the development and progression of RDEB-associated cSCC (RDEB-cSCC) remain somewhat of an enigma, and the evidence to date points towards a complex process. Currently, there is no cure for RDEB-cSCC, and treatments primarily focus on prevention, symptom management and support. Therefore, there is an urgent need for a comprehensive understanding of this cancer's pathogenesis, with the aim of facilitating the discovery of drug targets. This review explores the current knowledge of RDEB-cSCC, emphasising the important role of the immune system, genetics, fibrosis, and the tumour-promoting microenvironment, all ultimately intricately interconnected.

Abstract
BACKGROUND Epidermolysis bullosa (EB) is a group of rare hereditary diseases, characterized by fragility of the skin and mucous membranes. Epidemiological data on EB in Brazil are scarce. OBJECTIVES To describe epidemiological aspects of patients with EB diagnosed in the Dermatology Department of a tertiary hospital, from 2000 to 2022. METHODS An observational and retrospective study was conducted through the analysis of medical records. The evaluated data included clinical form, sex, family history, consanguinity, age at diagnosis, current age, time of follow-up, comorbidities, histopathology and immunomapping, presence of EB nevi and squamous cell carcinomas (SCC), cause of and age at death. RESULTS Of 309 patients with hereditary EB, 278 were included. The most common type was dystrophic EB (DEB), with 73% (28.4% dominant DEB, 31.7% recessive DEB and 12.9% pruriginous DEB). Other types were junctional EB with 9.4%, EB simplex with 16.5% and Kindler EB with 1.1%. Women accounted for 53% and men for 47% of cases. Family history was found in 35% and consanguinity in 11%. The mean age at diagnosis was 10.8 years and the current age was 26 years. The mean time of follow-up was nine years. Esophageal stenosis affected 14%, dental alterations affected 36%, malnutrition 13% and anemia 29%. During diagnostic investigation, 72.6% underwent histopathological examination and 92% underwent immunomapping. EB nevi were identified in 17%. Nine patients had SCC. Eleven patients died. STUDY LIMITATIONS Insufficient data included to medical records, loss to follow-up, and unavailability of genetic testing. CONCLUSIONS In this study, dystrophic EB predominated and the need for multidisciplinary care for comorbidities and complications was highlighted.

Abstract
Recessive dystrophic epidermolysis bullosa (RDEB) is a rare genetic disease resulting from inadequate type VII collagen (C7). Although recurrent skin blisters and wounds are the most apparent disease features, the impact of C7 loss is not confined to the skin and mucous membranes. RDEB is a systemic disease marred by chronic inflammation, fibrotic changes, pain, itch, and anemia, significantly impacting QOL and survival. In this narrative review, we summarize these systemic features of RDEB and promising research avenues to address them.

Abstract
In the context of rare genetic diseases caused by nonsense mutations, the concept of induced stop codon readthrough (SCR) represents an attractive avenue in the ongoing search for improved treatment options. Epidermolysis bullosa (EB)-exemplary for this group of diseases-describes a diverse group of rare, blistering genodermatoses. Characterized by extreme skin fragility upon minor mechanical trauma, the most severe forms often result from nonsense mutations that lead to premature translation termination and loss of function of essential proteins at the dermo-epidermal junction. Since no curative interventions are currently available, medical care is mainly limited to alleviating symptoms and preventing complications. Complementary to attempts of gene, cell and protein therapy in EB, SCR represents a promising medical alternative. While gentamicin has already been examined in several clinical trials involving EB, other potent SCR inducers, such as ataluren, may also show promise in treating the hitherto non-curative disease. In addition to the extensively studied aminoglycosides and their derivatives, several other substance classes-non-aminoglycoside antibiotics and non-aminoglycoside compounds-are currently under investigation. The extensive data gathered in numerous in vitro experiments and the perspectives they reveal in the clinical setting will be discussed in this review.

Abstract
The effect of persistent skin inflammation on extracutaneous organs and blood is not well studied. Patients with recessive dystrophic epidermolysis bullosa (RDEB), a severe form of the inherited blistering skin disorder, have widespread and persistent skin ulcers, and they develop various complications including anaemia, hyperglobulinaemia, hypoalbuminaemia and secondary amyloidosis. These complications are associated with the bioactivities of IL-6, and the development of secondary amyloidosis requires the persistent elevation of serum amyloid A (SAA) level. We found that patients with RDEB had significantly higher serum levels of IL-6 and SAA compared to healthy volunteers and patients with psoriasis or atopic dermatitis. Both IL-6 and SAA were highly expressed in epidermal keratinocytes and dermal fibroblasts of the skin ulcer lesions. Keratinocytes and fibroblasts surrounding the ulcer lesions are continuously exposed to Toll-like receptor (TLR) ligands, pathogen-associated and damage-associated molecular pattern molecules. In vitro, TLR ligands induced IL-6 expression via NF-κB in normal human epidermal keratinocytes (NHEKs) and dermal fibroblasts (NHDFs). SAA further induced the expression of IL-6 via TLR1/2 and NF-κB in NHEKs and NHDFs. The limitation of this study is that NHEKs and NHDFs were not derived from RDEB patients. These observations suggest that TLR-mediated persistent skin inflammation might increase the risk of IL-6-related systemic complications, including RDEB.

Abstract
Dystrophic epidermolysis bullosa is a rare genetic disease caused by damaging variants in COL7A1, which encodes type VII collagen. Blistering and scarring of the ocular surface develop, potentially leading to blindness. Beremagene geperpavec (B-VEC) is a replication-deficient herpes simplex virus type 1-based gene therapy engineered to deliver functional human type VII collagen. Here, we report the case of a patient with cicatrizing conjunctivitis in both eyes caused by dystrophic epidermolysis bullosa who received ophthalmic administration of B-VEC, which was associated with improved visual acuity after surgery.

Abstract
Background Recessive dystrophic epidermolysis bullosa (RDEB) is a rare inherited skin fragility disorder requiring multidisciplinary management. Information regarding costs of current standard treatment is scant. Objectives As part of a longitudinal natural history study, we explored the community care costs of UK patients with different forms of RDEB. Methods Fifty-nine individuals with RDEB provided detailed information on multiple facets of RDEB including disease severity scores (iscorEB, BEBS) and patient reported outcomes (quality of life evaluation in epidermolysis bullosa, iscorEB patient questionnaire). Costs data included time spent doing dressings, frequency of dressing changes, details of materials used, and paid and unpaid care. Results Overall costs of dressing materials and associated care were high in RDEB. Median annual costs across all subtypes for those using dressings (n = 51) were over £26 000. For severe RDEB (RDEB-S), median costs were almost £90 000 per annum, with a median of 18 h per week spent on dressing changes. Half of working-age adults with RDEB were unemployed and 39% of carers were unable to take on full-time or part-time paid employment, adding to indirect costs and the financial burden from RDEB on families and society. Conclusions The findings demonstrate the high costs of care of RDEB, particularly for RDEB-S. The current expense supports the drive to develop new therapies which accelerate wound healing and diminish total wound burden, thereby reducing costs of dressings and care. While costly to bring to market, these might ultimately reduce the overall cost of treatment and also the impact on individuals living with this rare disease. The data also highlight the need for adequate reimbursement for EB care which can place significant financial strain on families.

Abstract
Epidermolysis bullosa (EB) is a group of rare, difficult-to-treat, inherited multisystem diseases affecting epithelial integrity. Impaired wound healing is central and can lead to serious clinical complications, deformities, and symptoms with a devastating impact on quality of life (QoL). Dressing changes and wound care are central to the management of EB. Recently Oleogel-S10 (also known as birch bark extract or birch triterpenes) was approved in Europe and the UK for treating EB wounds. This approval was based on data from the EASE phase 3 study, which demonstrated Oleogel-S10 accelerated wound healing, reduced total wound burden, and decreased the frequency of dressing changes in patients with EB. A retrospective analysis of medical records was conducted for up to 24 months in 13 patients with EB treated with Oleogel-S10 through an early access programme in Colombia. Effectiveness was assessed by measuring body surface area percentage (BSAP) and total body wound burden (EBDASI). Tolerability and safety were monitored throughout. This is the first report to evaluate the effectiveness of Oleogel-S10 in clinical practice. The results showed a reduction in percentage of BSA affected, from a mean of 27.3% at baseline to 10.4% at 24-month follow-up, despite treatment interruptions. A reduction in EBDASI skin activity score of - 16.2 (24 months) together with a reduced skin damage index score of - 15.4 (18 months) was also observed. Physicians, patients, and caregivers perceived faster wound closure. Adherence with therapy by patients was good, and patients expressed satisfaction with treatment and reported improvements in self-esteem, productivity, and social interaction. Oleogel-S10 was well tolerated; however, two patients reported worsening wounds related to gauze adherence. Two deaths during treatment interruption were reported and was not considered related to Oleogel-S10. This study supports the effectiveness of Oleogel-S10 in a real-world scenario in a country with scarce resources for the treatment of EB.

Abstract
INTRODUCTION AND OBJECTIVES epidermolysis bullosa (EB) is a rare genetic disease characterised by skin fragility with blisters and erosions on the skin and/or mucous membranes. People with EB often experience several extracutaneous manifestations, including clinical and health-related quality of life (HRQoL) complications. Herein, we evaluate their HRQoL and clinical severity and propose an objective criterion for estimating nutritional compromise using the Birmingham Epidermolysis Bullosa Severity Score (BEBS) tool. METHODS this series of cases included people with EB, monitored by a multi-professional team. Clinical severity was assessed with the BEBS, using body mass index ranges by age, as an objective proposal, to estimate the degree of nutritional compromise. To assess HRQoL, the Children's Dermatology Life Quality Index (individuals aged 4-16 years) and the Quality of Life Evaluation in Epidermolysis Bullosa - Brazilian Portuguese (individuals 17 years and over) were used. RESULTS of the nine individuals with recessive dystrophic EB (88.9 % female and 12.91 (SD = 11.71) years), the mean total BEBS score was 24.47 (SD = 12.80) points on a scale of 0 to 100 points. Six participants had significant nutritional compromise according to the proposed criteria. Five of the six participants evaluated for HRQoL reported experiencing some impact, with individuals aged 17 and over being more affected and with greater clinical severity. CONCLUSIONS individuals with greater clinical severity of EB experience a more significant impact on their HRQoL. The proposed quantitative criteria for assessing nutritional compromise may help standardise assessments by professionals monitoring the nutritional status of individuals with EB.

Abstract
Background Epidermolysis bullosa (EB) is a painful genodermatosis presenting with skin fragility and blisters. There is no cure; the prognosis is guarded and depends on the subtype of the disease. Managing these patients can be emotionally challenging for healthcare practitioners. Aim To determine the perceptions, impact, and needs of healthcare practitioners (HCP) caring for patients and their families with EB. Setting Nelson Mandela School of Medicine, Durban and Grey's Hospital, Pietermaritzburg, KwaZulu-Natal. Methods The study was guided by interpretative phenomenological analysis. Individual in-depth interviews were conducted with 10 healthcare practitioners. Guba's trustworthiness framework was used to ensure rigour. Results Six global themes were identified, each related primarily to the perceptions, impact, and needs of healthcare practitioners. The experiences and perceptions of healthcare practitioners were that caring for patients with an incurable disease such as EB could negatively impact healthcare practitioners. There were divergent views among the disciplines of HCPs regarding the extent of care in a resource-limited environment. This resulted in negative emotions, ethical concerns, and a need for continued medical education and the application of coping strategies. Healthcare practitioners observed that patients and their families were vulnerable, requiring comprehensive biopsychosocial care. Conclusion Healthcare practitioners should be aware of their emotional challenges, seek support where necessary, and use effective coping strategies and self-care. Contribution The concerns and needs of healthcare practitioners are highlighted and interventional strategies to assist healthcare practitioners are suggested which will ultimately improve patient care.

Abstract
BACKGROUND Itch is common and distressing in epidermolysis bullosa (EB) but has not previously been studied in depth in different recessive dystrophic EB (RDEB) subtypes. OBJECTIVES As part of a prospective register study of the natural history of RDEB we explored features of itch, medications used, and correlation with disease severity and quality of life. METHODS Fifty individuals with RDEB aged 8 years and above completed the Leuven Itch Scale (LIS) (total 243 reviews over a 7-year period). Data included itch frequency, severity, duration, distress, circumstances, consequences, itch surface area and medications for itch. The iscorEB disease severity score and the validated EB quality of life tool, QOLEB, were compared to LIS domains and analysed by RDEB subtype. RESULTS Itch was frequent, present in the preceding month in 93% of reviews. Itch severity and distress were significantly greater in severe (RDEB-S) and pruriginosa (RDEB-Pru) subtypes compared to intermediate RDEB (RDEB-I). Itch medications were reported in just over half of reviews including emollients, topical corticosteroids and antihistamines; the proportion of participants not using medication despite frequent pruritus suggests limited efficacy. In inversa RDEB (RDEB-Inv) and RDEB-I, LIS domains correlated with iscorEB and QOLEB. In contrast to previous studies, correlations were lacking in RDEB-S suggesting that global disease burden relatively reduces the contribution of itch. CONCLUSIONS This comprehensive study of RDEB-associated itch highlights differences between RDEB subtypes, suggests an unmet need for effective treatments and could serve as control data for future clinical trials incorporating itch as an endpoint.

Abstract
BACKGROUND Epidermolysis bullosa (EB) is a rare, genetically and clinically heterogeneous group of skin fragility disorders. No cure is currently available, but many novel and repurposed treatments are upcoming. For adequate evaluation and comparison of clinical studies in EB, well-defined and consistent consensus-endorsed outcomes and outcome measurement instruments are necessary. OBJECTIVES To identify previously reported outcomes in EB clinical research, group these outcomes by outcome domains and areas and summarize respective outcome measurement instruments. METHODS A systematic literature search was performed in the databases MEDLINE, Embase, Scopus, Cochrane CENTRAL, CINAHL, PsycINFO and trial registries covering the period between January 1991 and September 2021. Studies were included if they evaluated a treatment in a minimum of three patients with EB. Two reviewers independently performed the study selection and data extraction. All identified outcomes and their respective instruments were mapped onto overarching outcome domains. The outcome domains were stratified according to subgroups of EB type, age group, intervention, decade and phase of clinical trial. RESULTS The included studies (n = 207) covered a range of study designs and geographical settings. A total of 1280 outcomes were extracted verbatim and inductively mapped onto 80 outcome domains and 14 outcome areas. We found a steady increase in the number of published clinical trials and outcomes reported over the past 30 years. The included studies mainly focused on recessive dystrophic EB (43%). Wound healing was reported most frequently across all studies and referred to as a primary outcome in 31% of trials. Great heterogeneity of reported outcomes was observed within all stratified subgroups. Moreover, a diverse range of outcome measurement instruments (n = 200) was identified. CONCLUSIONS We show substantial heterogeneity in reported outcomes and outcome measurement instruments in EB clinical research over the past 30 years. This review is the first step towards harmonization of outcomes in EB, which is necessary to expedite the clinical translation of novel treatments for patients with EB.

The Fraser Complex Proteins (Frem1, Frem2, and Fras1) Can Form Anchoring Cords in the Absence of AMACO at the Dermal–Epidermal Junction of Mouse Skin. Int J Mol Sci 2023; 24:ijms24076782. [PMID: 37047755 PMCID: PMC10095167 DOI: 10.3390/ijms24076782] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/03/2023] [Revised: 03/29/2023] [Accepted: 04/01/2023] [Indexed: 04/09/2023] Open
Abstract
AMACO (VWA2 protein), secreted by epithelial cells, is strongly expressed at basement membranes when budding or invagination occurs in embryos. In skin, AMACO associates with proteins of the Fraser complex, which form anchoring cords. These, during development, temporally stabilize the dermal–epidermal junction, pending the formation of collagen VII-containing anchoring fibrils. Fraser syndrome in humans results if any of the core members of the Fraser complex (Fras1, Frem1, Frem2) are mutated. Fraser syndrome is characterized by subepidermal blistering, cryptophthalmos, and syndactyly. In an attempt to determine AMACO function, we generated and characterized AMACO-deficient mice. In contrast to Fraser complex mutant mice, AMACO-deficient animals lack an obvious phenotype. The mutually interdependent basement membrane deposition of the Fraser complex proteins, and the formation of anchoring cords, are not affected. Furthermore, hair follicle development in newborn AMACO-deficient mice showed no gross aberration. Surprisingly, it appears that, while AMACO is a component of the anchoring cords, it is not essential for their formation or function.

Abstract
Staphylococcal infections in neonates might be associated with skin blistering since early antibiotic therapy has been shown to limit infection spread and positively influence outcomes; therefore, neonatologists should be aware of these conditions. This review examines the recent literature on the management of Staphylococcal infections that involve neonatal skin, discussing the most appropriate clinical approach to four cases of neonatal blistering diseases with Staphylococcal infections: a case of Staphylococcal bullous impetigo, a case of Staphylococcal scalded skin syndrome (SSSS), a case of epidermolysis bullosa with overlapping Staphylococcal infection, and a case of burns with overlapping Staphylococcal infection. In treating Staphylococcal infections involving skin in neonates, the presence or absence of systemic symptoms should be considered. In the lack of evidence-based guidelines in this age category, treatment should be individualized according to several factors including the extension of the disease or further skin comorbidities (such as skin fragility), with a multidisciplinary approach.

Abstract
PURPOSE Dystrophic epidermolysis bullosa (DEB) is a devastating condition that causes painful corneal abrasions and vision loss. Epidermolysis Bullosa Eye Disease Index (EB-EDI) for the first time captures and quantifies EB-specific assessment of ocular symptoms and activities of daily living scales. This survey will become critical in developing new interventions on patients' quality of life. METHODS Three-part set of the EB-EDI baseline, EB-EDI interval, and Ocular Surface Disease Index (OSDI) survey was distributed to 92 patients with DEB who previously reported eye symptoms on previous surveys. It was then posted online through several EB patient organizations. We compared the EB-EDI with the gold standard OSDI and examined the repeatability of the EB-EDI over a 7- to 15-day interval. RESULTS Of the 45 individuals who initially responded, 30 of 45 (67%) completed the surveys sent 7 to 15 days later. The age of participants ranged from 6 to 51 years (mean 21 ± 15 years), and 60% (18 of 30) of participants were younger than 18 years. The overall Cronbach alpha values for the subscales of EB-EDI baseline and interval tools presented a good internal consistency (≥0.7). From 2 visits, the domain scores of EB-EDI baseline (0.94) and interval tools (0.83) were shown to have excellent test-retest reliability (intraclass correlation coefficient >0.8). By comparison, OSDI had the intraclass correlation coefficient score of 0.72 ± 0.11. The convergent validation analysis showed that correlations between the domain scores of EB-EDI baseline and interval tools and the subscales of the OSDI reached the hypothesized strength. CONCLUSIONS Based on a 30-person repeated-measures study, we found that the EB-EDI has excellent reliability and validity specifically in patients with DEB.

Abstract
Introduction Autosomal recessive dystrophic epidermolysis bullosa (RDEB) is a rare disease with an early onset and severe phenotype. The pathogenic mechanism associated with mutations in the gene COL7A1 has been widely studied and many related cases have been reported, but prenatal cases are rare. Here, we report the prenatal diagnosis of a sporadic case of RDEB. Methods In this study, the fetus with abnormal skin manifestations, which were determined during a prenatal ultrasound, was evaluated based on the ultrasound and autopsy findings and the results of molecular diagnostic analyses. Samples of the fetus and the parents were subjected to trio whole-exome sequencing, and in vitro functional analyses were conducted to analyze the pathogenicity of the detected mutation. Results During the conventional prenatal ultrasound, the fetus showed abnormal epidermal lines on both lower limbs and the plantar skin as well as an interruption of the continuity of the lateral epidermal line below the ankle of the right lower limb. Gene testing revealed a homozygous nonsense mutation in COL7A1 (c.7411C>T, p.Arg2471Ter), which gave rise to RDEB in the fetus. Further, the results of the in vitro functional experiments confirmed that the mutation might lead to protein degradation. Conclusion Most prenatal diagnoses of RDEB are the result of targeted molecular analyses carried out based on family history, and prenatal ultrasound reports of severe RDEB phenotypes are extremely rare. Our case suggests that the observation of abnormal epidermal lines should be given due consideration during prenatal diagnosis, as they may be a sign of possible epidermolysis bullosa.

Abstract
BACKGROUND Epidermolysis bullosa (EB) is a group of rare genetic skin conditions that result in skin fragility. EB can be quite severe with chronic inflammation and malnutrition impairing growth and pubertal development. These factors have potential consequences for skeletal health. We aimed to determine the prevalence of delayed puberty and low bone mineral density (BMD) for age in children and young adults with EB. METHODS Electronic medical records (EMR) of patients with confirmed EB <30 years of age at time of initial encounter at Cincinnati Children's Hospital Medical Center between January 1, 2010 and September 30, 2020 were reviewed. Natural language processing software was used to categorize pubertal status of patients with EB as early, normal or delayed. BMD was measured by dual energy x-ray absorptiometry and categorized as low if height adjusted Z-score was <-2.0 using age, sex and race specific reference ranges. RESULTS 29% of individuals with EB had low BMD with most cases occurring prior to 10 years of age. Of patients who reached adolescence, 23% failed to develop any signs of puberty in the normal range (before age 13 in females or 14 in males) and BMD Z-scores further declined in these individuals. CONCLUSION Delayed puberty is an under-recognized comorbidity of individuals with EB, especially in those with recessive dystrophic EB, and can have a significant impact on BMD.

Targeted NGS in Diagnostics of Genodermatosis Characterized by the Epidermolysis Bullosa Symptom Complex in 268 Russian Children. Int J Mol Sci 2022; 23:ijms232214343. [PMID: 36430820 PMCID: PMC9698894 DOI: 10.3390/ijms232214343] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/27/2022] [Revised: 11/15/2022] [Accepted: 11/16/2022] [Indexed: 11/22/2022] Open
Abstract
The pathogenic variants of genes encoding proteins, participating in the formation and functioning of epidermis and dermo-epidermal junctions, create a large variety of clinical phenotypes from: small localized to severe generalized dermatitis, as well as early, or even, prenatal death due to extensive epidermis loss. The diagnostic panel in this study was developed for the purposes of identifying these pathogenic genetic variants in 268 Russian children, who possessed the epidermolysis bullosa symptom complex in a selection of 247 families. This panel included the targeted areas of 33 genes, which are genetic variants that can lead to the development of the phenotype mentioned above. The usage of next generation sequencing allowed the revelation of 192 various altered alleles (of which 109 alleles were novel, i.e., had not been described previously). In addition, it allowed the definition of the genetic variants that are both typical for most of the examined children and for the separate ethnic groups inhabiting modern Russia. We found that the most characteristic mutations for the Dargin and Chechen ethnic groups are the c.3577del deletion in the COL7A1 gene and the c.2488G>A missense mutation in the COL17A1 gene, respectively. In addition, the study of haplotypes of microsatellite markers, which we managed to conduct in the Dargin population, confirmed the presence of the founder effect.

Abstract
Introduction: Epidermolysis bullosa (EB) is a skin fragility disorder that is caused by molecular aberrations in the epidermal basement membrane zone. Based primarily on the cleavage plane within the skin, EB is classified into four major subtypes: EB simplex; junctional EB (JEB); dystrophic EB; and Kindler EB. The junctional form (JEB) can lead to blistering and a variety of extracutaneous complications, including genitourinary tract involvement. Despite therapeutic progress, treatment modalities for urological complications of JEB are currently limited. Results: We present the case of a Chinese male with intermediate JEB and profound urinary tract stenosis. Due to the progression of the urinary tract stenosis, he presented with repeated urological symptoms, such as high frequency of urination, painful urination, and difficult voiding. After birth, multiple blisters on the fingers, feet, and limbs, as well as nail dystrophies and spare hair were noted. Mutation analysis revealed that the patient carried a homozygous frameshift mutation in the LAMB3 gene [c.1172_1179delinsTGTGTGTGCAAGGAG/p. (P391Lfs*23)]. After receiving treatment for urethral dilatation, lingual mucosa for anterior urethroplasty, and repair of urethral stricture using a ventral onlay penile skin flap, the patient still experienced a relapse of urinary tract stenosis. Finally, the patient underwent perineal urethrostomy. In contrast, his older brother with similar urological symptoms received regular urethral dilatation, and the curative effect was positive. Conclusion: Here we report on a case with a novel LAMB3 mutation that led to JEB with profound urinary tract stenosis, which has expanded our experience in the treatment of EB urological complications.

Abstract
Inherited epidermolysis bullosa (EB) is a group of genetic rare diseases associated with skin fragility, which leads to the formation of blisters, erosions, and scars on the skin and mucous membranes. Epidermolysis bullosa includes four main types and some several clinical subtypes including EB simplex, junctional EB, dystrophic EB, and Kindler's EB. Ocular involvement ranged from 51 to 68% in EB and can cause irreversible damages if not properly managed. Corneal erosions are the most common finding among series, including our cohort. We review here clinical and pathological features of ocular involvement in EB and the main keys for management, with a focus on recent innovative therapies.

Abstract
Background
Delayed puberty is a possible complication of Epidermolysis Bullosa (EB), though the actual incidence is still unknown. In chronic illnesses delayed puberty should be correctly managed since, if untreated, can have detrimental effects on adult height attainment, peak bone mass achievement and psychological health.
Aims and methods
This is a single-centre study on pubertal development, growth and bone status in EB. Auxological, densitometric (areal Bone Mineral Density-aBMD Z-score, Bone Mineral Apparent Density-BMAD Z-score, Trabecular Bone Score-TBS and Bone Strain Index-BSI at Lumbar spine) and body composition data (Total Body DXA scans) were collected. Disease severity was defined according to Birmingham Epidermolysis Bullosa Severity (BEBS) score.
Results
Twenty-one patients (12 Recessive Dystrophic EB-RDEB, 3 Dominant Dystrophic EB, 3 Junctional EB-JEB, 2 EB Simplex and one Kindler EB) aged 13 years (females) or 14 years (males) and above were enrolled (age 16.2±2.5 years, M/F 11/10). Short stature was highly prevalent (57%, mean height -2.12±2.05 SDS) with 55% patients with height <-2SD their mid-parental height. 7/21 patients (33%, 6 RDEB and 1 JEB) had delayed puberty with a median BEBS of 50 (range 29 to 63), a height SDS of -2.59 SDS (range -5.95 to -2.22) and a median lumbar BMAD Z-score of -4.0 SDS (range -5.42 to -0.63 SDS). Pubertal status was negatively associated with BEBS, skin involvement, inflammatory state and positively with height SDS and BMI SDS.
Conclusions
Pubertal delay is highly prevalent in EB, especially in patients with RDEB and JEB, high severity score and inflammatory state. Moreover, pubertal delay worsens growth impairment and bone health. A study on pubertal induction is ongoing to enlighten possible beneficial effects on adult height attainment and peak bone mass accrual.

Understanding the socioeconomic costs of dystrophic epidermolysis bullosa in Europe: a costing and health-related quality of life study. Orphanet J Rare Dis 2022; 17:346. [PMID: 36068590 PMCID: PMC9450448 DOI: 10.1186/s13023-022-02419-1] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2022] [Accepted: 06/30/2022] [Indexed: 11/26/2022] Open
Abstract
Background Dystrophic epidermolysis bullosa (EB) is a family of rare genetic dermatological conditions. Recent evidence indicated that in addition to its detrimental implications on patient health-related quality of life (HRQoL), there are substantial socioeconomic cost implications, especially regarding direct non-medical costs. This study aims to understand the burden of dystrophic EB (DEB) in Europe, using a primary EB patient-level dataset.
Methods A bottom-up, cross-sectional, study design was adopted for non-institutionalised patients diagnosed with EB who received outpatient care across EU5 countries: France, Germany, Italy, Spain, and the United Kingdom. A prevalence-based approach was used to estimate resource utilisation from a societal perspective, including direct (medical and non-medical) and indirect costs for patients and caregivers. Patient and caregiver outcomes were obtained using the EQ-5D questionnaire. Results A sample of 91 DEB patients was analysed. Overall, average EU5 annual cost per patient was estimated at €53,359, ranging from €18,783 (France) to €79,405 (Germany). Average EU5 annual direct medical costs were estimated at €8357 (15.7% of total), ranging from €5658 (France) to €12,576 (Germany); average direct non-medical costs were estimated at €41,353 (77.5% of total), ranging from €11,961 (France) to €57,000 (Germany); and average indirect costs were estimated at €3649 (6.8% of total), ranging from €1025 (Italy) to €9930 (United Kingdom). Costs varied across patients with different disability but also between children and adults. The mean EQ-5D index score for adult DEB patients ranged between 0.304 (United Kingdom) and 0.541 (Germany), with an EU5 average of 0.456, whereas the mean EQ-5D visual analogue scale score ranged between 47.5 (Germany) and 70.0 (France), with an EU5 average of 61.9. Limitations included potential patient selection bias, recall bias, and exclusion of bandaging and related costs. Conclusions The study revealed a substantial socioeconomic burden for DEB in Europe, attributable mostly to high direct non-medical costs, with the majority of patients requiring support from caregivers at home. Compared to the average economic burden of the overall EB patient population, costs for DEB patients are higher across all components of direct medical, direct non-medical and indirect costs.

Abstract
BACKGROUND Standardized assessments for dystrophic epidermolysis bullosa (DEB) are needed. This prospective, multicenter, 4-week, observational study was designed to evaluate DEB assessments for suitability as clinical trial endpoints. METHODS Patients with confirmed DEB diagnosis and ≥ 5 measurable wounds were included. The primary outcome was change from baseline in wound surface area (WSA) of 5 selected wounds by 3-dimensional imaging. Secondary endpoints were change from baseline in clinician global assessment (CGA) of WSA, wound characteristics, disease-related questionnaires and instruments (disease severity, quality of life [QoL], pain and disability, and itch), and tolerability of procedures. RESULTS Of 30 enrolled patients, 29 completed the study (of whom, 28 had recessive DEB). Median age was 17.8 years (range, 3.8-58.7). All patients developed new or recurrent wounds during the 4-week study. Of the wounds selected at baseline, 45/150 (30.0%) healed by week 2; an additional 38 healed by week 4, while 8 of those healed at week 2 had recurred by week 4 for a total of 75/150 (50.0%) healed wounds at week 4. Mean values for WSA, CGA, and disease-related questionnaire and instrument scores remained steady during this 4-week observational study. Of the 10 disease-related questionnaires and instruments assessed, the scores for the Epidermolysis Bullosa Disease Activity and Scarring Index (EBDASI) and the Instrument for Scoring Clinical Outcomes for Research of Epidermolysis Bullosa (iscorEB) did not substantially overlap between moderate and severe disease. Between mild and moderate disease, only the EBDASI scores did not substantially overlap. CONCLUSIONS These results stress the dynamic nature of wounds, even during a 4-week period of observation, and suggest that a combination of clinician-assessed outcomes and patient-/caregiver-reported outcomes is needed to provide a comprehensive assessment of DEB severity and impact. In addition, these results support the use of EBDASI and iscorEB to monitor disease severity as both produced scores that did not substantially overlap between disease severity strata.

Abstract
Recessive dystrophic epidermolysis bullosa (RDEB) manifests with blistering and erosions of the skin and mucous membranes due to mutations in COL7A1. The repetitive wound healing processes lead to extensive cutaneous scarring. The scarring is driven by inflammatory processes, particularly the TGF-β signaling pathways, resulting in excess synthesis and deposition of the extracellular matrix, especially collagen. There is currently no effective or specific treatment for RDEB. Losartan, an angiotensin II type 1 receptor antagonist, is an inhibitor of TGF-β activity. Previous preclinical studies with hypomorphic Col7A1 mice recapitulating features of RDEB have suggested that losartan may improve the clinical features of RDEB. In this case series, we assessed the effects of losartan on the clinical and histopathologic features in seven patients with RDEB; three females and four males; ages 18.1 ± 9.1 years. The diagnosis was based on characteristic clinical features and the presence of biallelic loss-of-function mutations in COL7A1. Daily oral administration of losartan (0.7 mg/kg) for six weeks resulted in subjective improvement of the clinical features, as judged by the treating physicians and the patients, and the severity of the disease objectively improved based on Birmingham Epidermolysis Bullosa Severity (BEBS) score (30.1 ± 12.8 vs. 23.3 ± 10.4, before and after treatment, p = 0.018), accompanied by improvement of quality of life, as determined by the EB-QoL questionnaire (24.0 ± 8.1 vs. 17.7 ± 5.5, p = 0.018). Histopathology of the selected lesions revealed increased number of mast cells, and enhanced microvasculature in the mid and lower dermis. The width of collagen bundles in dermis was suggested to be decreased in four samples and changed from dense to loose in appearance. In summary, this case series reports beneficial effects of losartan on RDEB as a potentially novel treatment. This article is protected by copyright. All rights reserved.

Abstract
AbstractEpidermolysis bullosa (EB) is a severe hereditary disease characterized by defective epithelial adhesion causing mucocutaneous fragility. The major types are EB simplex (EBS), junctional EB (JEB), dystrophic EB (DEB) and more than 35 EB subtypes. Another very rare type of EB is Kindler EB (KEB). Clinically, it is a very heterogeneous disease which ranges from localized to extensive skin lesions with frequent multisystem extra cutaneous involvement. The role of a pediatrician-dermatologist cooperation within a multidisciplinary team is fundamental for both the diagnosis and management contributing to these patients’ better life expectancy. Aim of this study is to describe clinical and laboratory characteristics of the main EB subtypes focusing on nutritional and gastrointestinal aspects, providing information to aid the paediatric management of children with EB. This retrospective study reviewed the cases of 160 pediatric EB patients (76 male and 84 female): 31 patients affected by EBS (mean age ± SD: 4.37 ± 7.14), 21 patients affected by JEB (mean age ± SD: 9.26± 17.30) and 108 with DEB (mean age ± SD: 11.61 ± 13.48). All patients were admitted at the Bambino Gesù Children’s Hospital in Rome, between June 2005 to June 2020. The reduced gastrointestinal absorption, chronic losses, esophageal stenosis and chronic inflammatory state, represent the basis of nutritional problems of EB patients. In particular, anemia represents one of the most important complications of DEB patients which could require transfusion-dependent patterns. Malnutrition, vitamin deficiencies and anemia have been related to growth delay in EB patients. A specific diet with a balance of all macronutrients is required and improving caloric intake with sugar limitations is fundamental to prevent dental caries and tooth decay typical of EB patients. While sepsis proved to be the major cause of morbidity and mortality in younger patients, squamous cell carcinoma was mostly observed in older patients, especially those affected by DEB. Patients with EB require regular monitoring for complications and sequelae with a frequency of evaluations which varies based on age and EB subtypes. Cooperation among medical teams involving paediatricians, dermatologists, specialist clinicians including nutritionists such as families and patient’s association is fundamental to approach the disease and improve the quality of life of these patients.

Abstract
Epidermolysis bullosa (EB) is a rare heterogeneous genetic mechanobullous skin disorder that is characterized by increased skin fragility leading to blistering following minor trauma. EB may be inherited as an autosomal dominant or an autosomal recessive disorder and can be classified into dystrophic EB (DEB), junctional EB (JEB), and EB simplex (EBS). A total of 28 Saudi patients with EB were included in this observational, retrospective chart-review study. A consecutive non-probability sampling technique was used to approach all affected patients. Molecular analysis was done to test the patients’ genomic DNA using a custom-designed AmpliSeq panel of suspected genes. All disease-causing variants were checked against available public databases. Twelve patients (42.9%) were found to have DEB, 6 patients (21.4%) with JEB, and 10 patients (35.7%) with EBS. The molecular genetic results revealed detections of 24 various homozygous genetic variations in the genes associated with EB, of which 14 were novel mutations. The most frequent variations were detected in COL7A1 in 12 cases (42.9%), followed by LAMB3 in 5 cases (17.9%), TGM5 in 4 cases (14.3%), and other genes. Furthermore, the majority (87.5%) of EB cases were confirmed to have homozygous mutations, and few were documented with positive consanguinity history. Only 3 cases (12.5%) were found to be autosomal dominant displaying heterozygous mutations. This is the first study to establish the EB genetic profile in Saudi Arabia where DEB is the most frequent type. A total of 14 novel mutations were identified that had not been previously reported. Consanguineous marriage is clearly recognized in the Saudi population; therefore, we propose a nationwide EB program that would help extend the spectrum of the genetic profile and help in the diagnosis and better understanding of this disease.

Abstract
BACKGROUND The mutational analysis along with immunofluorescence antigen mapping (IFM) are recommended as the laboratory tools of choice for diagnosing EB. In the past, transmission electron microscopy (TEM) was considered the gold standard, and more recently, clinical diagnostic matrix (CDM) has shown good concordance with next-generation sequencing (NGS). MATERIALS AND METHODS In this prospective diagnostic study, a skin biopsy was taken for TEM and IFM in consecutive patients with EB (aged >6 months) diagnosed clinically with CDM. Wherever possible, mutational analysis was done using targeted NGS. RESULTS Of the 80 patients diagnosed with CDM, skin biopsies of 42 patients were assessed using TEM, and of 59 patients using IFM. NGS was done in 39 patients. Taking NGS as the gold standard for diagnosing EB (n = 39 patients), the concordance with CDM, TEM and IFM were estimated at 84.6% (33/39), 78.5% (11/14), and 76% (19/25) respectively. CDM showed a substantial agreement with NGS (k = 0.69, P < 0.001). CONCLUSIONS In comparison to NGS, the highest concordance was seen with CDM followed by TEM and IFM in diagnosing major subtypes of EB. This article is protected by copyright. All rights reserved.

Abstract
Cutaneous disease can often be an initial clue of an underlying cardiovascular disease. Many congenital conditions (ie, Noonan syndrome with multiple lentigines, Carney complex, and Fabry disease) and acquired conditions may present initially with specific cutaneous features that should prompt clinicians to conduct a full cardiac workup. Given the extensive number of conditions with both cardiovascular and cutaneous findings, this review will focus on diseases with cardiocutaneous pathology with hopes of raising clinician awareness of these associations to decrease morbidity and mortality, as several of these diseases often result in fatal outcomes.

Abstract
Inherited epidermolysis bullosa (EB) comprises rare disorders that manifest with fragility and blistering of the skin and mucous membranes, with variable clinical severity. Management of EB is challenging due to disease rarity and complexity, the wide range of extracutaneous manifestations and a profound impact on daily life for the patient and family members. Although reference centres providing multidisciplinary care for EB exist in each European country, it is common for healthcare professionals that are not specialized in this rare disorder to treat EB patients. Here, experts of the European Reference Network for Rare and Undiagnosed Skin Diseases (ERN-Skin, https://ern-skin.eu) propose practical recommendations for the diagnosis and management of the commonest clinical issues, skin blisters and wounds, oral manifestations, pain and itch.

Abstract
Epidermolysis bullosa (EB) encompasses a phenotypically and genetically heterogeneous group of inherited skin disorders characterized by blistering and erosions of the skin with minimal trauma. Dystrophic EB (DEB), both dominant and recessive, can be associated with several extracutaneous manifestations, including musculoskeletal deformities. Congenital deformities of the feet have rarely been reported in the literature. We describe an infant with dominant DEB and congenital absence of the skin who presented with congenital brachydactyly of the bilateral great toes.

Abstract
Non-viral gene therapy for hereditary skin diseases is an attractive prospect. However, research efforts dedicated to this area are rare. Taking advantage of the branched structural possibilities of polymeric vectors, we have developed a gene delivery platform for the treatment of an incurable monogenic skin disease - recessive dystrophic epidermolysis bullosa (RDEB) - based on highly branched poly(β-amino ester)s (HPAEs). The screening of HPAEs and optimization of therapeutic gene constructs, together with evaluation of the combined system for gene transfection, were comprehensively reviewed. The successful restoration of type VII collagen (C7) expression both in vitro and in vivo highlights HPAEs as a promising generation of polymeric vectors for RDEB gene therapy into the clinic. Considering that the treatment of patients with genetic cutaneous disorders, such as other subtypes of epidermolysis bullosa, pachyonychia congenita, ichthyosis and Netherton syndrome, remains challenging, the success of HPAEs in RDEB treatment indicates that the development of viable polymeric gene delivery vectors could potentially expedite the translation of gene therapy for these diseases from bench to bedside.

Abstract
Epidermolysis bullosa (EB) is a group of rare, inherited diseases characterized by skin fragility and multiorgan system involvement that presents many anesthetic challenges. Although the literature regarding anesthetic management focuses primarily on the pediatric population, as life expectancy improves, adult patients with EB are more frequently undergoing anesthesia in nonpediatric hospital settings. Safe anesthetic management of adult patients with EB requires familiarity with the complex and heterogeneous nature of this disease, especially with regard to complications that may worsen during adulthood. General, neuraxial, and regional anesthetics have all been used safely in patients with EB. A thorough preoperative evaluation is essential. Preoperative testing should be guided by EB subtype, clinical manifestations, and extracutaneous complications. Advanced planning and multidisciplinary coordination are necessary with regard to timing and operative plan. Meticulous preparation of the operating room and education of all perioperative staff members is critical. Intraoperatively, utmost care must be taken to avoid all adhesives, shear forces, and friction to the skin and mucosa. Special precautions must be taken with patient positioning, and standard anesthesia monitors must be modified. Airway management is often difficult, and progressive airway deterioration can occur in adults with EB over time. A smooth induction, emergence, and postoperative course are necessary to minimize blister formation from excess patient movement. With careful planning, preparation, and precautions, adult patients with EB can safely undergo anesthesia.

Abstract
New insights into molecular genetics and pathomechanisms in epidermolysis bullosa (EB), methodological and technological advances in molecular biology as well as designated funding initiatives and facilitated approval procedures for orphan drugs have boosted translational research perspectives for this devastating disease. This is echoed by the increasing number of clinical trials assessing innovative molecular therapies in the field of EB. Despite remarkable progress, gene-corrective modalities, aimed at sustained or permanent restoration of functional protein expression, still await broad clinical availability. This also reflects the methodological and technological shortcomings of current strategies, including the translatability of certain methodologies beyond preclinical models as well as the safe, specific, efficient, feasible, sustained and cost-effective delivery of therapeutic/corrective information to target cells. This review gives an updated overview on status, prospects, challenges and limitations of current gene-targeted therapies.

Abstract
BACKGROUND Infection is an important complication of epidermolysis bullosa (EB), and Staphylococcus aureus has been pointed out as the most common pathogen among this population. The objective of this study was to investigate the prevalence and antimicrobial resistance profile of S. aureus colonizing EB patients in Brazil. METHODS This cross-sectional multicenter study was conducted between December 2015 and December 2017. We included a total of 89 individuals with EB from medical centers across Brazil. Data were obtained through clinical and bacteriological investigation. S. aureus were identified by biochemical tests. The nuc and mecA genes were confirmed by PCR assay. Antimicrobial susceptibility was investigated by disk diffusion method. RESULTS The overall prevalence of S. aureus was 51.7% (46/89). Methicillin-resistant S. aureus (MRSA) was detected in 24.7% (19/77) of all S. aureus isolates, colonizing 15.7% (14/89) of all patients. Community-associated (CA)-MRSA strains were resistant against sulfamethoxazole/trimethoprim and levofloxacin (P < 0.05%). S. aureus colonization of the nares and belly button represented a 3.4 times higher risk of simultaneous skin lesion colonization (P < 0.05%). CONCLUSIONS The high frequency of MRSA colonizing patients with EB is alarming considering its association with life-threatening complications and poorer outcomes. EB patients are at increased risk of colonization and infection by Staphylococcus aureus and CA-MRSA. Getting to know S. aureus carriage sites and its antimicrobial susceptibility profile is key when planning new individualized and more effective prophylactic and therapeutic measures.

Abstract
BACKGROUND AND OBJECTIVE Epidermolysis bullosa (EB) is a heterogeneous group of inherited disorders characterized by a high degree of mucocutaneous fragility. This study aimed to describe the clinical and epidemiologic characteristics of patients with EB treated in Hospital Universitario La Paz, a national referral center for inherited EB. MATERIAL AND METHODS Observational, retrospective, single-center study. We included all cases with a clinical and molecular diagnosis of EB managed in the hospital's dermatology department from January 2, 2000, to February 28, 2021. RESULTS A total of 214 cases were studied. The median (interquartile range) age was 17 (8-32) years; 54.2% were women. One hundred thirty-five (63.1%) patients had dystrophic EB, 67 (31.3%) had EB simplex, 8 (3.7%) had junctional EB, and 3 (1.4%) had Kindler syndrome. One (0.5%) had EB acquisita. Over a third (35.5%) of the patients resided in Madrid. The most common clinical complications were pruritus (63.1%), local infections (56.5%), and pain (54.7%). The most serious ones were cardiomyopathy (in 5.6%) and squamous cell carcinoma (10.3%). Twenty-two patients (10.3%) died. CONCLUSIONS Dystrophic EB was the most prevalent clinical form. The most prevalent complications were pruritus, pain, and infections. The most serious ones were cardiomyopathy and squamous cell carcinoma. This study is the first in Spain that explores strategies for improving the health status and quality of life of patients with EB.

Abstract
Intermediate junctional epidermolysis bullosa caused by mutations in the COL17A1 gene is characterized by the frequent development of blisters and erosions on the skin and mucous membranes. The rarity of the disease and the heterogeneity of the underlying mutations renders therapy developments challenging. However, the high number of short in-frame exons facilitates the use of antisense oligonucleotides (AON) to restore collagen 17 (C17) expression by inducing exon skipping. In a personalized approach, we designed and tested three AONs in combination with a cationic liposomal carrier for their ability to induce skipping of COL17A1 exon 7 in 2D culture and in 3D skin equivalents. We show that AON-induced exon skipping excludes the targeted exon from pre-mRNA processing, which restores the reading frame, leading to the expression of a slightly truncated protein. Furthermore, the expression and correct deposition of C17 at the dermal-epidermal junction indicates its functionality. Thus, we assume AON-mediated exon skipping to be a promising tool for the treatment of junctional epidermolysis bullosa, particularly applicable in a personalized manner for rare genotypes.

Abstract
BACKGROUND Recessive dystrophic epidermolysis bullosa (RDEB) is an incurable disease that causes severe mucocutaneous fragility due to mutations in COL7A1 (encoding type VII collagen [C7]). In this phase I/IIa trial, we evaluated the safety and possible clinical efficacy of intravenous infusion of allogeneic human umbilical cord blood–derived mesenchymal stem cells (hUCB-MSCs) in patients with RDEB. METHODS Four adult and two pediatric patients with RDEB were treated with 3 intravenous injections of hUCB-MSCs (1 × 106 to 3 × 106 cells/kg) every 2 weeks and followed up for 8–24 months after treatment. The primary endpoint was safety. Secondary endpoints related to efficacy included clinical parameters, such as disease severity score, wound assessment, itch and pain score, and quality of life. C7 expression levels and inflammatory infiltrates in the skin, as well as serum levels of inflammatory markers and neuropeptides, were also assessed. RESULTS Intravenous hUCB-MSC infusions were well tolerated, without serious adverse events. Improvements in the Birmingham Epidermolysis Bullosa Severity Score, body surface area involvement, blister counts, pain, pruritus, and quality of life were observed with maximal effects at 56–112 days after treatment. hUCB-MSC administration induced M2 macrophage polarization and reduced mast cell infiltration in RDEB skin. Serum levels of substance P were decreased after therapy. Increased C7 expression was observed at the dermoepidermal junction in 1 of 6 patients at day 56. CONCLUSION To the best of our knowledge, this is the first clinical trial of systemic administration of allogeneic hUCB-MSCs in patients with RDEB, demonstrating safety and transient clinical benefits.

Supporting sexuality for people living with epidermolysis bullosa: clinical practice guidelines. Orphanet J Rare Dis 2021; 16:9.

Abstract
This article presents evidence-based Clinical Practice Guidelines (CPG) for the provision of healthcare services to address sexuality for people living with epidermolysis bullosa (EB). Currently, a lack of EB-specific research limits these services to sexual health assessment and intervention strategies designed for the general population. Due to the unique challenges of EB, a rare skin-fragility condition causing blistering responses to minor skin trauma and other systemic and secondary complications, condition-specific strategies are needed to support people with EB in achieving valued sexual lifestyles. This CPG represents the work of an international panel comprised of thirteen members including a medical doctor, nurses, psychologists, a social worker, an occupational therapist, and patient population involvement members living with EB. It describes the development of EB-specific recommendations for two primary domains of assessment and intervention related to sexuality: psychosocial and mechanical. Following a rigorous evidence-based guideline development process, this CPG establishes the first internationally actionable clinical practice recommendations for sexuality-related assessment and intervention for this population. Future research priorities are identified. Supplemental materials included provide additional support to clinicians in developing the necessary understanding and skills to promote equity and efficacy in this care domain.
