Gross motor development in children with epidermolysis bullosa.

BACKGROUND

Epidermolysis bullosa (EB) is a group of rare, congenital skin disorders, characterized by skin fragility and formation of blisters. The gross motor outcomes of children with EB are not known.

OBJECTIVES

The primary objective of the study was to measure the proportion of gross motor delay in children with EB. The secondary objectives were to measure the difference in gross motor outcomes between EB sub-types and change in gross motor outcomes over time.

METHODS

Children with EB, aged between one month and five and a half years of age, attending the Sydney Children's Hospital, Epidermolysis Bullosa Clinic, were eligible. Carers completed Ages and Stages Questionnaires, Third Edition, on behalf of their children. Questionnaires were scored, and outcomes were compared to age-expected norms.

RESULTS

There were 24 participants to complete a questionnaire. Eleven participants completed additional questionnaires over the 24 month study duration. The proportion of children with EB with gross motor delay was greater than age-expected norms (29.17% vs. 2.5%). The delay occurred in children with recessive dystrophic (80%) and epidermolysis bullosa simplex (33.33%) sub-types, but not dominant dystrophic (0%). No children with Junctional EB or Kindler EB joined this study.

CONCLUSIONS

This study demonstrates a difference in gross motor outcomes in children with EB. Children with recessive dystrophic and epidermolysis bullosa simplex should be prioritized for monitoring of, and intervention for, gross motor outcomes through multidisciplinary care. Further research investigating long-term outcomes for children with EB and the effectiveness of interventions would be beneficial.
