We plan to obtain skin biopsies from patients with systemic sclerosis and healthy donors to grow cells from biopsies. With those cells, we will use them in experiments to see why the cells from systemic sclerosis patients have more fibrosis compared to patients without systemic sclerosis.

The objective of this study is to evaluate the efficacy of augmenting traditional autografting with Stratagraft. Stratagraft is a synthetic human-tissue based regenerative skin device, which was designed to decrease the amount of donor tissue needed to treat severe burn wounds. Patients who participate in this study are asked to complete assessments, such as wound photography, wound healing progression, and scar progression, at multiple timepoints during a 1 year period.

In current practice, options for venous and lymphatic malformations remain limited. Recently an oral medication, sirolimus, has been found to benefit patients when taken once or twice a day for several months. Unfortunately there are many side effects associated with this medication, some of which can be severe including, neutropenia, oral ulcerations, and lab abnormalities. The purpose of this study is to determine if once weekly dosed sirolimus will be effective for the treatment of venous and lymphatic malformations. Additionally, the study will evaluate patient satisfaction and identify adverse effects. Participants will be on the medication for 6 months with an option to continue after this time period.

This is a 5-year, longitudinal, observational study of adult and pediatric patients (all ages) being treated for Immune-Mediated Inflammatory Skin Conditions. In addition to the study database, a biospecimen repository will be included in order to perform studies on biomarkers of response.

Patients being prescribed medical therapy for IMISC will be eligible for enrollment. Treatment algorithms will follow each site's local standard of care and no specific treatments, assessments, and/or laboratory tests will be dictated by enrollment in the main TARGET-DERM Program. Patients will be screened and enrolled at a regularly scheduled clinic visit. Up to three years of retrospective
medical records from patients who provide consent/assent and meet all inclusion and exclusion criteria will be obtained by the research site. Records will include but will not be limited to: hospitalizations, laboratory reports, clinic notes, telephone contact reports, medication lists, reasons for medication initiation and/or discontinuation, biopsy results, and imaging. Patients may
also be linked to external databases (such as patient support programs). Patients will also be asked to provide biological samples and complete patient reported outcome (PRO) surveys, although participation in these two portions is optional.

During the follow-up period, the research site will prospectively submit the research subjects' medical records approximately every 6 to 12 months, for up to 5 years. Patients/legal representatives ("parent proxy") will be asked to complete PRO surveys at regular intervals during this follow-up period.

This study will assess the features of children, younger than 12 years old, with moderate to severe eczema, also known as atopic dermatitis, when their condition is not adequately controlled with topical therapies (creams or lotions) or when those therapies are not medically advisable.

This is not a treatment study. You and your child will complete questionnaires describing how their condition effects them. Information related to your child's illness will be collected by reviewing their medical chart and by assessments performed by the study team. Participation in this study will involve at least 12 visits that will take place over a period of 10 years.

The information collected in this study may lead to an improved understanding of your child's illness and may provide healthcare providers with important information for treating atopic dermatitis in the future.

The goal of this study is to develop an early systemic sclerosis (SSc) registry in the United States (US). A registry is a group of patients that are observed over time. This is a non-interventional study, meaning that they are no study specific medications to take or procedures to undergo. The specific aims include ongoing assessment of the natural history of early SSc patients by capturing and analyzing clinical data, patient reported outcomes, and laboratory data as seen in the clinic as part of their routine care needs. Additional study visits are not required. This is a multi-center study with sites spread across the U.S. This study is funded by the Scleroderma Research Foundation.
