Use of a Transdermal Patch to Noninvasively Monitor Inflammatory Biomarkers of Acute and Chronic Skin GVHD

Brief Summary

Detailed Description

Acute skin graft versus host disease is a significant complication following allogeneic stem cell transplant. To date, there are no specific dermal biomarkers that predict or define the onset of acute skin graft versus host disease. The primary objective of this study is to observe the changes in the inflammatory environment of the skin during the process of acute and chronic skin graft versus host disease. This will be accomplished by using a non-invasive transdermal patch called D-Squame to analyze inflammatory cytokines and key epidermal proteins. Patients will be enrolled prior to receiving a stem cell transplant and followed weekly after stem cell infusion until day 99. If acute skin graft versus host disease develops, they will be followed weekly until resolution of acute graft versus host disease or development of chronic graft versus host disease, whichever occurs first. Patients with a diagnosis of chronic skin graft versus host disease will be enrolled and followed weekly until 4 weeks, irrespective of clinical course. In addition, healthy controls will be enrolled and used as comparators. The relevance of this study is to provide a better understanding of the local inflammatory environment induced by acute or chronic skin graft versus host disease. This is likely to enable the investigators to define a biomarker panel that predicts the onset of acute graft versus host disease rapidly and non-invasively.
