[PMID: 37389358 PMCID: PMC10305771 DOI: 10.2147/ccid.s413093] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2023] [Accepted: 06/21/2023] [Indexed: 07/01/2023]
Abstract
Background Epidermolysis bullosa (EB) is a genodermatosis disease with bullae and erosions of the skin and mucous membrane that can last for a lifetime and decrease quality of life. Oral and gastrointestinal disorders inhibit the patients' ability to achieve optimal nutrition, making the patients prone to infection, leading to prolonged wound healing, and delayed growth and developmental process. However, there has been no research on the clinical, laboratory, and nutritional status of pediatric EB patients in Indonesia. Purpose This study aims to describe the clinical, laboratory, and nutritional characteristics of pediatric EB patients treated in Dr. Hasan Sadikin General Hospital Bandung, Indonesia. Patients and Methods This was a retrospective descriptive study of pediatric EB patient records in Dermatology and Venereology Outpatient of Dr. Hasan Sadikin General Hospital Bandung, Indonesia, from April 2018-March 2020. Results Study results showed 12 pediatric EB patients consisting of 7 dystrophic EB (DEB) (4 recessive dystrophic EB [RDEB] patients and 3 dominant dystrophic EB [DDEB]), 3 junctional EB (JEB), and 2 EB simplex (EBS). The most extensive EB wounds was found affecting 10-20% of the body surface area with a <10% infected wound area. Pain was found in all patients. The most frequent abnormalities in laboratory examination were anemia and low zinc levels. Severe malnutrition was found in almost half of the patients. Conclusion RDEB is the most commonly found type of pediatric EB. Wounds on the skin, tooth decay, hand deformity, pain when changing dressings, low zinc levels, and low hemoglobin levels are the clinical features and laboratory findings that contribute to the development of moderate and severe malnutrition in RDEB patients.

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.

Abstract
BACKGROUND Epidermolysis bullosa (EB) is a highly invalidating genodermatosis characterized by skin and mucosa fragility and blister-formation caused by mutations of genes encoding components of the cutaneous basement membrane zone. Nutritional impairment is one of the main complications of all forms of EB, having a huge impact on growth, pubertal development, wound healing, resistance to infections and quality of life. METHODS In our study we have retrospectively evaluated 17 children with EB to define whether nutritional impairment in those patients is already present in the neonatal period. As secondary outcomes we considered nutritional status differences among EB subtypes and relative percentages of underweight infants at birth, first and third month. Moreover, information concerning feeding modality, possible complications were also collected, as well as cutaneous or systemic infections and duration of hospital stay. RESULTS Our study demonstrated that nutritional impairment of neonates with EB has an early onset since as at first month 35% of patients were below 5th centile for weight-for-age, and 94% were below the 50th percentile. Moreover, the number of infants at one month of life <5th centile for weight-for-age was significantly higher compared to birth. The nutritional status is also heavily related to the occurrence of complications, in particular infections; therefore, the prevention of these complications must play a central role in the treatment of these infants, also to avoid any nutritional impairment. CONCLUSIONS Nutritional status of neonates with EB seems to be compromised already during the first month of life and it is heavily related to the occurrence of infections; therefore, the prevention of these complications must play a central role in the treatment of these infants, also to avoid any nutritional impairment.

Abstract
Epidermolysis bullosa (EB) is a group of rare congenital genetic conditions that result in painful blistering of the skin and mucous membranes, which occur with minor trauma or friction. There are many types and subtypes of EB that need to be distinguished, as the management and prognosis of each can vary significantly. We aim to perform an up-to-date literature review on congenital EB for healthcare providers in pediatrics. We performed a review of existing literature in the English language on EB via PubMed Clinical Queries, using key words such as "epidermolysis bullosa", "congenital" and "children". We reviewed EB based on the following subheadings: epidemiology, diagnosis, therapy, prognosis, and clinical prediction guidelines. EB is due to mutation in a number of genes, some types are autosomal dominant while others are autosomal recessive. The underlying mechanism is a defect in attachment between or within the epidermis and dermis of the skin. There are four main types: epidermolysis bullosa simplex, dystrophic epidermolysis bullosa, junctional epidermolysis bullosa, and Kindler syndrome. The diagnosis is suspected based on symptoms and confirmed by skin biopsy and definitive genetic testing. The severity of EB can range from mild to fatal. Severe complications may arise in some EB types and subtypes within the eye, ear, nose, upper airway, gastrointestinal and genitourinary tracts. There is no cure for the condition to date. Optimal management must be multidisciplinary, and involves wound care, pain control, controlling infections, nutritional support, and prevention and treatment of complications. EB presents in different forms. Treatment is supportive. The prognosis of milder forms is good. Children severely affected with EB and their families live a misery life with impaired quality of life. Health care workers must be aware of the suffering in these families and proactively support them.

Abstract
WHO defines malnutrition as severe if the z-scores are less than - 3 Standard deviation (SD), moderate if between - 2 and - 3 SD and mild if between - 2 SD to - 1 SD. This study was aimed to assess nutritional aspects of Indian children suffering from EB and to evaluate the effect of severity of EB on the severity of malnutrition. In this study, pediatric EB patients were evaluated prospectively for baseline nutritional status using anthropometric parameters and WHO growth charts, and its correlation with disease severity using instrument for Scoring Clinical Outcomes for Research of Epidermolysis Bullosa-iscorEB. In second phase, an individualized diet chart was given to meet the energy, protein and micronutrients needs and its effects were observed after 6 months. The median age of participants was 3 years (IQR-9). Of 57 patients, malnutrition was seen in 40.35% patients (22.81%-moderate and 17.54%-severe), and significantly correlated with iscorEB (r = 0.45, p < 0.0001). On bivariate regression analysis, iscorEB was independently associated with moderate-to-severe malnutrition (p = 0.047; OR 1.038, CI 1.011-1.066). iscorEB enabled the identification of patients with moderate-to-severe malnutrition with an Area Under Receiver Operating Curve (AUROC) of 0.72 (95%CI 0.58-0.85; p < 0.005). In phase 2, there was significant improvement in nutritional status in children with recessive dystrophic EB (RDEB) and dominant dystrophic EB (DDEB) subtype (p < 0.0001). The severity of malnutrition in EB children significantly correlates with disease severity, and is an independent predictor of moderate-to-severe malnutrition.

Abstract
THE AIM OF THE STUDY Was to assess dental age and the frequency of dental extractions in children with epidermolysis bullosa (EB) compared to controls. MATERIALS AND METHODS The study comprised 22 EB children (8 boys and 14 girls aged 4-16 years, mean age 11.1±3.5 years) and 25 healthy children (9 boys and 16 girls aged 4-14 years, mean age 10.1±2.4 years). Dental age was measured on panoramic X-ray by Demirjian method and then compared to child's physical age to estimate retardation or advance in dental maturity. RESULTS Only in 5 from 22 EB children dental age corresponded to physical age, there was dental age retardation in 7 patients (13 to 68 months, 27±21.5 months in average), but in 10 dental age exceeded physical (4 to 21 months, 12.9±7.8 months in average). In controls where was only one boy with dental age retardation by 18 months, in 7 children dental age corresponded to physical, in 17 dental age advance by 5-45 months (16.0±11.0 months in average) was revealed. Conclusion. Possible dental age retardation in EB patients should be considered when undertaking dental extractions for orthodontic reasons. For more precise orthodontic treatment timing further studies are needed to correlate dental age, skeletal age and BMI in children with EB.

Abstract
BACKGROUND Impaired growth and anaemia are major extracutaneous complications of epidermolysis bullosa (EB), but data on their development are lacking. OBJECTIVES To determine the clinical course of growth and anaemia in children with EB and clarify the impact of nutritional compromise, inflammation and genetic factors. METHODS A retrospective study was conducted of 200 children, 157 with recessive dystrophic EB (RDEB) and 43 with junctional EB (JEB)-generalized intermediate, followed at the main referral centre in Germany. Growth charts were calculated using the modified LMS method and were correlated with parameters of anaemia, nutrition, inflammation and the molecular defect in a linear model. RESULTS In our cohort of patients with RDEB, weight impairment started at 12-18 months old; by the age of 10 years, 50% showed wasting. The predicted median weight at age 20 years was 35·2 kg for men and 40·1 kg for women. In JEB, growth resembled that of healthy children. Anaemia was present from the second year of life onwards in RDEB and JEB. Low levels of haemoglobin, iron, vitamin D, zinc and albumin, high levels of C-reactive protein, and absence of collagen VII correlated significantly with low weight in RDEB. No correlation was observed in JEB. CONCLUSIONS The results highlight that nutritional compromise occurs early in children with RDEB and therefore may require interventions as of the first year or two of life. What's already known about this topic? Children with epidermolysis bullosa (EB) suffer from failure to thrive and anaemia as major extracutaneous complications. The course of growth and the development of anaemia in EB are poorly characterized. What does this study add? A molecularly well characterized cohort of 200 children with EB was followed with regard to anthropometrics, anaemia and inflammation. We demonstrate early onset of growth failure and anaemia, most pronounced in the subset of recessive dystrophic EB. Awareness of early growth delay and nutritional deficiencies will improve EB care in daily practice.

Abstract
Inherited epidermolysis bullosa (EB) is a clinically and genetically heterogeneous group of rare diseases characterized by skin and mucous membrane fragility. EB primarily involves the skin and, in specific subtypes, the mucous membrane, resulting in complications which can strongly affect nutritional status (e.g. gastrointestinal complications, hand deformities, pain). The aims of nutritional support mainly include improving nutritional status, alleviating the stress of oral feeding and minimizing nutritional deficiencies, thus consequently improving growth, pubertal development, bowel function, immune status and wound healing. The aim of this review is to discuss knowledge of different aspects of the disease related to nutrition and growth.

Abstract
Cell-cell junctions link cells to each other in tissues, and regulate tissue homeostasis in critical cell processes that include tissue barrier function, cell proliferation, and migration. Defects in cell-cell junctions give rise to a wide range of tissue abnormalities that disrupt homeostasis and are common in genetic abnormalities and cancers. Here, we discuss the organization and function of cell-cell junctions primarily involved in adhesion (tight junction, adherens junction, and desmosomes) in two different epithelial tissues: a simple epithelium (intestine) and a stratified epithelium (epidermis). Studies in these tissues reveal similarities and differences in the organization and functions of different cell-cell junctions that meet the requirements for the specialized functions of each tissue. We discuss cell-cell junction responses to genetic and environmental perturbations that provide further insights into their roles in maintaining tissue homeostasis.
