View clinical trials related to Lyell Syndrome.
Filter by:A phase IIa, open label, non controlled clinical trial to assess the feasibility and safety of allogeneic adipose-derived mesenchymal stem cells (ASC) in the treatment of cicatricial conjunctivitis associated with Lyell's syndrome, Stevens-Johnson's syndrome and mucous membrane pemphigoid with ocular involvement
Stevens-Johnson syndrome (SJS) and toxic epidermal necrolysis (TEN) are rare severe cutaneous adverse reactions (SCARs) to drugs. To date, no curative drug has demonstrated with a good level of evidence its ability to promote SJS and TEN healing and could contribute to earlier reepithelialisation. Mesenchymal stroma cells (MSCs) therapy represents a new therapeutic approach. eg, in patients with cardiovascular diseases, neurological diseases, renal transplantation, lung diseases as acute respiratory distress syndrome. Recently, MSCs have been proposed in both burn wound healing with a significantly decrease of the unhealed burn area and in cutaneous radiation. Moreover, MSCs have immunomodulation properties potentially effective in refractory acute and chronic graft versus host disease (GVHD) by improving thymic function and induction of Tregs. Indeed, MSCs are able to migrate to inflamed tissues after stimulation by pro-inflammatory cytokines and to modulate the local inflammatory reactions. MSCs have also demonstrated their ability to promote tissue remodelling, angiogenesis and immunomodulation through either differentiation or secretion of several growth factors such as VEGF, basic FGF and various cytokines. Therefore, combining their immunomodulation effect and secretion of soluble factors involved in wound repair, MSCs might be valuable as a cell therapy strategy for promoting cutaneous healing in SJS-TEN syndrome and subsequently decrease the morbi-mortality.
Intro: Dermatology department of Henri Mondor Hospital (Creteil, France), is a reference center for toxic bullous diseases and severe cutaneous drug reactions (Stevens-Johnson syndrome (SJS), Lyell syndrome (toxic epidermal necrolysis (TEN)), generalized bullous fixed drug reactions, AGEP, DRESS, drug induced immunoglobulin A (IgA) bullous dermatosis, and erythema multiforme). In order to conduct clinical and biological research studies in drug reactions, it is necessary for the investigator's department to implement a collection of clinical data and biological samples. Hypothesis/Objective: To collect clinical data and cutaneous and biological samples for immunological, biological and genetic studies to improve knowledge about pathophysiology of drug reactions. Method: The following samples will be performed in addition to the routine practice samples: one skin punch biopsy (6mm); 43 mL of blood; blister fluid aspiration; oral and nose mucous membrane and skin eSWABs, stool samples. These samples will be stored in a dedicated biological sampling department ("Platform of biological resources"). Conclusion: The implementation of this collection should allow us to conduct pathophysiological studies about drug reactions.
