NCT04321811
Background: During the current COVID-19 pandemic there is urgent need for information about the natural history of the infection in non-hospitalized patients, including the severity and duration of symptoms, and outcome from early in the infection, among different subgroups of patients. In addition, a large, real-world data registry can provide information about how different concomitant medications may differentially affect symptoms among patient subgroups. Such information can be invaluable for clinicians managing chronic diseases during this pandemic, as well as identify interventions undertaken in a naturalistic setting that have differential effects. Such factors may include patient diet, over the counter or prescription medications, and herbal and alternative treatments, among others. Identifying the natural disease history in patients from different demographic and disease subgroups will be important for identifying at-risk patients and effectiveness of interventions undertaken in the community. Objectives: The purpose of this study is to understand at the population level the symptomatic course of known or suspected COVID-19 patients while sheltering-in-place or under quarantine. Symptoms will be measured using a daily report derived from the CTCAE-PRO as well as free response. Outcomes will be assessed based on the duration and severity of infection, hospitalization, lost-to-follow-up, or death. As a patient-centric registry, patients themselves may propose, suggest, and/or submit evidence or ideas for relevant collection.

The purpose of this study is to test the safety of the experimental therapy of a single infusion of Regulatory T cells (Tregs). The investigators want to find out what effects, good or bad, Tregs will have on the kidney transplant patients. There are different types of T cells. This study uses Regulatory T cells (Tregs), which are found in the blood and are part of the immune system that stops other immune cells from working. Tregs help to turn off the immune system after other immune cells have finished tackling outside infections, and Tregs keep the immune system in check so that the body does not attack itself. The researchers are hoping that, by giving an infusion of Tregs that the attack on the kidney can be stopped and kidney function will be stabilized. It is not known if the Treg experimental therapy can stop the inflammation in the kidney. In this study, the researchers will take some of Tregs from the patient, multiply them in the laboratory, and then infuse them back into the patient. The procedure used to multiply Tregs is an experimental process performed in the laboratory. Similar procedures done with mice have been shown to reverse inflammation but it is not known whether the results will be the same in humans. This therapy has not yet been done in humans outside of a research study.
