COVID-19 testing involves collection of swabs from nasopharyngeal cavities where the SARS-CoV-2 virus replicates. Many other commensal and pathogenic microbes may be found in the same host niche. Collectively, these microbes are called the microbiome. We hypothesize that the colonizing microbiome at the time of diagnosis may provide leads for early stratification of cases into risk categories, future clinical manifestations of the disease, and insights into treatment strategies.
This is a 2-year, longitudinal, observational study of adult patients (ages 18 and above) being treated for moderate to severe plaque psoriasis.
Patients being prescribed or initiating medical therapy with a new biologic drug (such as risankizumab, guselkumab, brodalumab, tildrakizumab, ixekizumab, adalimumab, etanercept, ustekinumab, secukinumab, certilizumab pegol, infliximab, or apremilast) for the treatment of plaque psoriasis will be eligible for enrollment. The study will be conducted to gather data from enrolled patients' electronic health records, prospective physician-reported information provided by the patients' dermatologists, and information collected from questionnaires and surveys completed by the enrolled patients.
Patients will be screened and enrolled at a regularly scheduled clinic visit. 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, emergency room visits, procedures, and medical costs. Physician reported outcomes will be recorded at regularly scheduled visits. Patients will also be asked to complete patient reported outcome (PRO) surveys and questionnaires to record data regarding demographics, clinical characteristics of psoriatic disease, comorbidities, family history, occupation and lifestyle factors, use of PsO support programs, contact information, concomitant medication use, medication side effects, and symptom characteristics.
During the follow-up period, the research site will prospectively submit the research subjects' medical records approximately every 3 to 12 months, for up to 2 years. Patients will be asked to complete PRO surveys electronically at regular intervals during this follow-up period.
The purpose of this study is to find out more information about the study drug iloprost for the treatment of symptomatic Raynaud's phenomenon (RP) attacks in people with scleroderma. A Raynaud's attack is defined as one where you notice at least one color change of your finger(s) (blue, white, or red) associated with at least one symptom (pain, numbness, tingling, and/or discomfort of the finger[s]). Your participation in this study will last approximately 9 weeks and will include 8 visits to the study center and 1 phone call from the study staff.
The goal of this study is to learn more about lupus (Systemic Lupus Erythematosus; SLE), which affect African-Americans more than other groups. The purpose of this study is to understand what role microbes living in the intestine (called microbiota) have in causing lupus. This study will include males and females of all ethnic backgrounds who have SLE, individuals who have immediate family members with SLE, and unrelated healthy volunteers. For subject recruitment, CCCR/MCRC databases including the longitudinal SLE in Gullah Health (SLEIGH) study as well as the chart review will be used to screen for eligibility. The study is sponsored by the National Institutes of Health.
It is important to understand multiple personal-level factors that impact disease risks and outcomes to determine the most effective ways to establish precise medical strategies to prevent, diagnose, and treat chronic health conditions and diseases. This is especially important among minority and underserved populations that would benefit from more tailored healthcare approaches. This study will develop and assess strategies for circulating evidence about precision medicine and improving precision medicine approaches.
Often considered as related diseases, systemic lupus erythematosus (SLE) and systemic sclerosis (SSc) are severe autoimmune disorders characterized, among other, by dysregulation of immune cells in the blood. The roles of different immune cells in SLE and SSc remain unclear. It is of increasing importance to characterize specific immune cells and define their impact on autoimmune disease, which may lead to new therapies. The goal of this study is to identify blood immune cells associated with SLE and SSc.
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.
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.
