Scleroderma (systemic sclerosis) is a chronic autoimmune disease, characterized by dysregulation of immune cells in the blood and subsequent fibrosis and vascular dysfunction, associated with significant mortality and morbidity, disproportionately affecting women and African Americans, and without satisfactory treatments. Monocytes, a type of blood immune cells, are critically involved, but the mechanisms responsible for their deregulation in scleroderma remain largely unknown. The goal of this project is to understand how the regulation of monocytes differs between scleroderma and healthy individuals. Volunteers will be asked to provide a blood sample, for which modest compensation will be provided. This is not a drug study.
Many youth and young adults (YYAs) with type 1 diabetes (T1D) and type 2 diabetes (T2D), particularly those of minority race/ethnicity, do not achieve optimal glycemic control and household food insecurity (HFI) may be a key barrier. HFI is the limited or uncertain availability of nutritionally adequate and safe foods. The SEARCH Food Security (SFS) cohort study is designed as an ancillary study to the ongoing NIH/NIDDK-funded SEARCH for Diabetes in Youth 4 Cohort study. The aims of the SFS study are to (1) Initiate a food insecurity cohort study of 1,187 YYAs aged 15-35 years (53% minority) with T1D and T2D by adding two data collection time points to the ongoing SEARCH 4 study in three of the five SEARCH sites, including South Carolina, Colorado and Washington; (2) Evaluate how HFI influences changes in glycemic control in YYAs with T1D and T2D; (3) Identify the pathways through which food insecurity may act; and (4) Evaluate the influence of HFI on changes in health care utilization and medical and non-medical health care costs in YYAs with T1D and T2D.
Systemic lupus erythematosus (lupus; SLE) and Systemic Sclerosis (scleroderma; SSc) are relatively rare rheumatic diseases that disproportionately impact the African American community, and particularly African American women. The causes of lupus and scleroderma are unknown, but thought to include both genetic and environmental factors. We are enrolling lupus and scleroderma patients, and healthy control subjects. This is not a drug study. The purpose of this study is to better understand the factors that predispose people to develop lupus and scleroderma. Information about medical, social and family history, medications, physical exam findings, and laboratory tests will be collected for analysis. This study will involve approximately 1360 volunteers.
The Systemic Lupus Erythematosus (SLE) in Gullah Health, or SLEIGH, study is an observational study enrolling African Americans from the Sea Island communities of South Carolina and Georgia. We are enrolling patients, family members of patients, and unrelated community members. SLE is a potentially severe disease that can affect the entire body. SLE is more common in African Americans than Caucasians. The main purpose of this study is to find genes that, along with factors from the environment, result in the development of SLE. Volunteers in SLEIGH will be asked to answer questions about their health and have blood and urine collected for tests. After the first visit there may be one additional visit 2 or more years later. This is not a drug study.
