Brief Summary:

Skin wounds of Recessive Epidermolysis Bullosa Dystrophica (REBD) involve pain, superinfection, protein-losing, inflammation, and joint contractures are the bed of squamous cell carcinoma. There is no precise data on the kinetics of healing post-bullous erosions but clinical experience suggests that most epidermise in less than a month. Some, however, for unknown reasons, persist for several months. These chronic ulcers (UC), arbitrarily defined for this study as lasting more than three months are a source of major discomfort and could play a decisive role in the morbidity and mortality of the disease.

The aim of this study is to evaluate the efficacy of the amniotic membrane on the healing of chronic ulcers REBD on the percentage ulcerated surface re-epithelialised at 12 weeks (M3) from the start of treatment.

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 22 participants
Allocation: Randomized
Intervention Model: Single Group Assignment
Masking: Single (Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Comparative Study of the Healing of Chronic Skin Ulcers of Recessive Dystrophic Epidermolysis Bullosa : Standard Dressing Versus Amniotic Membrane.
Study Start Date : January 2015
Estimated Primary Completion Date : January 2018
Estimated Study Completion Date : January 2020

Arm Intervention/treatment
Active Comparator: Standard Dressing
J0 to J42 : once a week, primary dressing with Mepitel®
Device: Amniotic Membrane
Experimental: Amniotic Membrane
J0 to J42: once a week, Mepitel® and amniotic membrane (one or several depending on the graft size, so that the ulcer was completely covered with MAH). The last amniotic membrane is left in place.
Device: Amniotic Membrane

Primary Outcome Measures :
  1. Percentage of ulcerated area re-epithelialised [ Time Frame: at 12 weeks from the start of treatment ]
