The goal of the TrialNet Natural History Study of the Development of Type 1 Diabetes is to enhance the understanding of the demographic, immunologic, and metabolic characteristics of individuals at risk for developing type 1 diabetes. The Natural History Study will screen relatives of people with type 1 diabetes to identify those at risk for developing the disease. Male and female patients 1 year to 45 years of age who are first and second/third degree relatives of individuals with type 1 diabetes may be eligible to participate in this study.

The purpose of the study is to determine the feasibility of enrolling patients, obtaining colorectal cancer risk factor data via an in-person questionnaire, and procuring three types of biologic samples (normal mucosa biopsies, a salvia sample, and polyp tissue (if applicable)).
This study is for patient that have been diagnosed with suspected lower respiratory tract infection. The purpose of this study is to evaluate a new test that may be able to find more lung infections than current tests can. This new test is called next-generation sequencing and looks in respiratory secretions for bacteria, viruses, fungi, and other organisms that may cause infection. We hope to learn more about the usefulness of this new test in identifying infections.
Treatment of chronic hepatitis C virus (HCV) infection is now possible with all oral medications. While most patients achieve a sustained virologic response (SVR) after treatment, synonymous with cure, some patients relapse after treatment for reasons that are unclear. The goal of this research is to understand how a person's immune system changes during treatment of HCV infection with all oral therapy, and how these changes might impact the chances of relapse after treatment. To address these questions, blood and clinical information will be collected from study participants over the course of receiving standard of care treatment for HCV infection. This blood and clinical information will be used to conduct laboratory research focused on the immune system.
Systemic sclerosis (SSc) or scleroderma is an autoimmune disease in which a person?s own immune cells attack his/her skin and internal organs, including the joints, lungs, heart, intestinal tract, and kidneys. The effects on the lungs, including pulmonary arterial hypertension (PAH), are among the most serious complications of SSc. In general, PAH is defined as an increase in pressure in the pulmonary arteries (the main blood vessels that lead from the heart to the lungs). Treatments for PAH have focused on symptom management rather than curing the disease.
This study has been designed to look at a new approach to treating the cause of the disease, rather than the symptoms of the disease. Recent research suggests that SSc-PAH may be the result of an ?attack? by immune cells. This study will look at the effect of the drug rituximab on the immune system and the immune ?attack? on the lungs. Rituximab is an immunosuppressive drug that eliminates the B cells for a few months, and therefore may halt the B cell attack on the lungs thought to be associated with this disease.The recovery of your B cells will be closely monitored throughout the study by blood testing.
Schizophrenia is a highly heritable neurodevelopmental disorder, accompanied by impairment in a variety of day-to-day cognitive functions that are associated with exposure to certain herpesviruses. This project investigates the role of a major gene of the immune system in the etilogy of herpesvirus-spurred cognitive impairment. Results from these investigations could help devise novel immunotherapeutic interventions in this devastating disorder.
Keloid disease predominantly affects African Americans, Hispanics and some Asians. Keloid disease is characterized by an overgrowth of an area of the skin following some injury to that same skin area. It is unknown why this occurs. However, we believe that differences in Vitamin D along with dysfunction in certain immune system receptors can lead to keloid disease. To further understand this process we intend to study the cells (fibroblasts) in the skin that are affected by Vitamin D and examine the specific immune proteins.
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.
