Resting Energy Expenditure and Protein Balance in People with Epidermolysis Bullosa

Assessment of nutrient intakes of children and adolescents with recessive dystrophic epidermolysis bllosa, severe subtype

Introduction

Background and aims: epidermolysis bullosa (EB) is a rare disease presenting with skin fragility and formation of blisters. Constant presence of skin lesions, loss of blood, wastage of heat through the open skin, increased turnover of proteins and infections, result in increased energy, protein, and micronutrient needs. This study investigated the intake adequacy of energy, protein, zinc, iron, and dietary fiber in children with epidermolysis bullosa. Methods: this cross-sectional, analytical study was conducted with children and adolescents of up to 18 years of age with recessive dystrophic EB, severe subtype. Demographic data and clinical manifestations affecting food consumption were collected. Nutritional assessment was performed through anthropometric data. We used a formula to estimate specific energy needs for EB, and ratio of skin lesions was also evaluated to assist in estimating energy needs. A protein adequacy of 115 % to 200 % of the Recommended Dietary Allowance was considered for the adequacy of protein intake. And the Dietary Reference Intake tables according to sex and age were used as a reference for micronutrients. Intake assessment was performed using seven consecutive daily food records. Sip feed consumption was considered for intake assessment. Results: all patients showed undernutrition and presented at least three clinical symptoms that affect food consumption: pseudosyndactyly, microstomy, and blisters in the oral cavity. Sip feed constituted between 20 % and 50 % of the patients' energy intake. Intake of iron and zinc was adequate for most patients (confidence of adequacy ≥ 0.85), while fiber intake was below the reference value. Conclusions: this study underscores the importance of nutritional monitoring for EB patients, which is often interpreted as a skin disease but has enormous nutritional repercussions.

Gastrostomy tube feeding in epidermolysis bullosa: A multi-center assessment of caregiver satisfaction

BACKGROUND/OBJECTIVES

Gastrostomy tubes (G-tubes) are a feasible intervention for nutritional support in patients with epidermolysis bullosa (EB) who suffer from gastrointestinal involvement. However, some parents may be apprehensive about this surgical intervention. The purpose of this study is to assess caregiver satisfaction and experiences after G-tube insertion in children with EB.

METHODS

Nine institutions sent an anonymous 89-item online questionnaire to caregivers of patients with EB and active G-tubes during an 8-week study period. The questionnaire consisted of eight sections and was formatted with multiple choice, Likert scales, dichotomous scales (yes/no), and free text.

RESULTS

Twenty caregiver surveys were completed. All caregivers were parents (100%). The average age of G-tube placement was 2.7 years (SD: 2.1, range 0-8) and duration of the G-tube utilization was an average of 12.0 years (SD: 7.8, range 1-25). EB subtypes were dystrophic (n = 15/20, 75%), junctional (n = 3/20, 15%), and simplex (n = 2/10, 10%). Almost all caregivers (n = 18/20, 90%) reported high levels of satisfaction with G-tube management (scores > 20 on the modified SAGA-8 scale). More than half of caregivers (n = 12/20, 60%) reported that, retrospectively, they would have desired earlier adoption of the G-tube. Caregivers rated mealtimes as more enjoyable and easier both for themselves and the individual with EB post-G-tube placement.

CONCLUSION

The survey demonstrates a high rate of satisfaction for G-tube use among caregivers of patients with EB across varying ages and household settings. The free-text responses provide unique insight into caregiver's individual experiences regarding G-tubes to be considered for future studies.

Plasma metabolomic profiling reflects the malnourished and chronic inflammatory state in recessive dystrophic epidermolysis bullosa

BACKGROUND

Recessive dystrophic epidermolysis bullosa (RDEB) is a hereditary blistering disorder characterized by skin fragility, chronic inflammation, malnutrition, and fibrosis. Metabolomics is an emerging investigative field that helps elucidate disease pathophysiology and identify biomarkers. However, previous metabolomic studies in RDEB are limited.

OBJECTIVE

To investigate the plasma metabolomic profiles in RDEB patients.

METHODS

We recruited 10 RDEB patients and 10 age-/gender-matched healthy controls. Peripheral blood samples were collected and plasma metabolomic profiling was performed by LC-MS/MS analysis. MS data processing and compound identification were executed by MS-DIAL. Enrichment analysis was performed by MetaboAnalyst 5.0.

RESULTS

Metabolomic analyses demonstrated that most amino acid levels were downregulated in RDEB patients, and the extent of insufficiency correlated with clinical severity. Several metabolites were dysregulated in RDEB, including glutamine and glutamate metabolism, tryptophan-to-kynurenine ratio, phenylalanine-to-tyrosine ratio, and succinate accumulation.

LIMITATIONS

The study was limited by small case numbers and the unrepresentativeness of a single time-point blood sample.

CONCLUSION

Our study demonstrated the altered metabolomic profiles in RDEB, reflecting the disease severity, the chronic inflammatory and malnourished status, while the fibrotic signatures were not evident.

Epidermolysis Bullosa: A case study in Cyprus and the nursing care plan

PURPOSE

To present a case study with Epidermolysis bullosa (EB) in Cyprus and to determine the nursing care plan, explaining the nursing interventions and showing the importance of nursing care of patients with EB.

METHODS

Literature review on EB and semi-structured interviews commenced through a direct discussion with open-ended questions to the research subject as well as to a close relative describing his feelings, experiences, and concerns about the disease.

FINDINGS

Thematic analysis approach was used to identify and analyze patterns in the data. Then, data were synthesized using the standardized nursing terminology of NANDA-I and the Nursing Interventions Classification. The accuracy of the diagnoses and the appropriateness of the nursing interventions were supported by the positive health outcomes of the patient.

CONCLUSIONS

Nurses should apply evidence-based practice interventions for EB wound care, pain management, nutrition, psychological and social support to these patients.

IMPLICATIONS FOR NURSING PRACTICE

Although EB is classified in the category of rare diseases, the presentation of a case study in Cyprus and the nursing care plan contribute further bibliographically to the holistic and at the same time individualized nursing practice.

Natural history of growth and anaemia in children with epidermolysis bullosa: a retrospective cohort study

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.
