Genetic changes to human skin contribute to a wide variety of conditions and diseases that affect over 20% of the population. However, the genes and molecules that are responsible for human skin development and disease are not fully understood, preventing the development of treatment options. This proposal seeks to better understand one disease in particular, linear morphea, a form of Sclerederma that can affect the skin, muscle, and bone. This study will recruit subjects to collect and use skin tissue for the purpose of identifying the genetic causes of linear morphea.

BLUE CORAL is an observational, biorepository study for patients who are hospitalized with COVID-19. The study collects various data and biospecimens, such as blood, urine, and tracheal aspirates, during the patient's hospital stay. The data and biospecimens collected will be used to provide greater knowledge on the biology and epidemiology of COVID-19.

Understanding the current epidemiology of COVID-19 is of urgent importance in light of the continued pandemic. Given current testing guidelines, the number of individuals within the Charleston, South Carolina area who have had COVID-19 is unknown. Many such individuals may have been asymptomatic or mildly symptomatic. Thus, the number of confirmed cases, those who are or have been symptomatic and tested for COVID-19, is most likely a significant underrepresentation of the community seroprevalence of the virus. The purpose of this study is to determine the number of prior COVID-19 infections that are present in the Charleston area among adults, and to evaluate characteristics associated with infection with SARS-CoV-2, the virus which causes COVID-19.

This study will examine immunity to COVID-19 infection in healthy individuals, healthy transplant patients, and patients diagnosed with COVID-19. Blood samples will be collected from participants over a period of 3 years that will be tested for immunity.

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.

The purpose of this study is to compare the effects, good or bad, of study treatment with remdesivir plus tocilizumab compared with remdesivir by itself on subjects with severe COVID19 pneumonia. In this study, the subject will receive standard supportive care treatment for COVID-19 pneumonia as well as remdesivir, and will additionally receive either tocilizumab, or placebo. About 450 people will take part in this study. Depending on the early results of the study, the total number of people who will take part may be increased to up to 800.

People who recover from COVID-19 do so, at least in part, because their blood contains substances called antibodies, which are capable of fighting the virus that causes the illness. It turns out that for some other diseases caused by respiratory viruses, giving people the liquid portion of blood, called plasma, obtained from those who have recovered from the virus, leads to more rapid improvement of the disease. This study hopes to investigate if patients with COVID-19 improve faster if they receive plasma from those who have recovered from COVID-19.

The Medical University of South Carolina (MUSC) is developing a COVID-19 biorepository which will contain blood, urine, and other bodily fluids along with relevant medical information from individuals evaluated, exposed to, or treated for COVID-19. To learn from this pandemic ,and to develop treatments and strategies to better prepare and avert future pandemics we must study the disease and its effects. The clinical specimens in the biorepository will be available for investigators to use for future research. Compensation is provided for participation in this project for eligible participants.

The purpose of this study is to estimate the extent to which health care workers at MUSC who may have higher than average risk for exposure to the novel coronavirus SARS-CoV-2, which causes an illness referred to as COVID-19, may have developed immunity to infection. Two groups of people will be asked to participate in this study. The first group is comprised of health care workers with a potentially higher risk of exposure who may have provided direct care or services for persons with SARS-CoV-2 infection as part of their work duties. The second group is comprised of employees whose job duties do not involve direct contact with patients. The purpose of the research is to determine if a certain marker in blood, IgG to SARS-CoV-2, can tell if participants may have been exposed to and now recovered from SARS-CoV-2 infection and how seroprevalence changes over time during the current outbreak in this population of study subjects.

This is a blinded, multicenter, placebo-controlled randomized clinical trial. In this trial, the safety and effectiveness of hydroxychloroquine for the treatment of adults hospitalized with COVID-19 will be evaluated. In this study, a medication called hydroxychloroquine is being investigated to see if it improves recovery from COVID-19 in patients admitted to the hospital. Hydroxychloroquine is used to treat malaria and some joint (rheumatologic) diseases, but it is unknown if it helps patients recover from COVID-19. Study medication will be given for 5 days. This medication could be either hydroxychloroquine or placebo. There will be up to 510 patients in the study at about 50 hospitals in the United States.
