Background: Generalized recessive dystrophic epidermolysis bullosa (RDEB) is often complicated by high nutritional difficulties with risks of malnutrition.
Objectives: To provide information regarding the benefits of enteral feeding by gastrostomy (GTF), energy and protein requirements, tolerance, growth and pubertal development in children with RDEB.
Methods: Twenty-four patients were referred over a 7-year period in a retrospective study. Gastrostomy placement was decided in patients unable to feed orally and/or presenting loss in weight and height of at least 1 SD compared with their best growth level, despite regular nutritional advice. Weight and height were expressed as Z-scores. Catch-up growth following GTF onset was studied.
Results: Gastrostomies were performed in 11 children (aged 9·0±5·8years), and one young man aged 18years. The body weight Z-score was -2·3±1·0, height Z-score 1·1±1·1, weight-for-height was 81±11% and height-for-age 95± 4%. At onset, GTF provided 74±21% and 180±81% of the recommended dietary allowance (RDA) for energy and proteins, respectively. At study update (53±20months), GTF provided 91±29% and 205±100% of RDA for energy and proteins, respectively. Weight-for-height reached 92±15% and height-for-age 98±5%. A normal puberty was obtained when GT was performed before the age of 10years. Skin was not improved.
Conclusion: Malnutrition was observed in 50% of the children with generalized RDEB. Protein and energy needs are particularly high. GTF is well tolerated and helps with catch-up growth and puberty. It must be considered before malnutrition onset, and, if necessary, before puberty.
