Background: People who get COVID-19 have a wide range of symptoms. They also recover from COVID-19 in different ways. In this study, researchers will use survey data to describe the different ways people experience and recover from COVID-19. They will also use the data to help create future studies to understand why some people do not fully recover. Objective: To learn more about the range and timing of symptoms that people have before, during, and after COVID-19 infection. Eligibility: People ages 18 and older who can give documentation of a positive COVID-19 or antibody test. Design: Participants will be screened with a telephone interview. It will take 15 minutes. They will provide their COVID-19 test results and medical records. Participants will complete a second telephone interview. It will take 30 60 minutes. They will also take online surveys every 3 months for 3 years. The interview and surveys will ask participants about their health before they got COVID-19, what happened while they had COVID-19, and what their recovery has been like. Participants will get log-in data to take the online surveys. Completing all of the surveys the first time may take up to 3 hours. Follow-up surveys will take up to 30 minutes. Participants do not have to complete the surveys in one sitting. They will be able to save their progress and finish the surveys later. Participants may be contacted to take part in other research studies.

Plasma from patients who have recovered from coronavirus disease 2019 (COVID-19) is referred to as COVID-19 convalescent plasma (CCP), and may contain antibodies against SARS-CoV-2, the virus responsible for COVID-19. CCP infusion is being evaluated as a therapeutic or prophylactic approach in COVID-19 patients. The goal of this study is to help develop a bank of convalescent plasma in California, especially in medically underserved communities particularly affected by the disease. In parallel, CCP administered to COVID-19 patients will be collected and analyzed to determine whether the antibody profile correlates with clinical outcome. The purpose of this non-therapeutic study is to learn more about the CCP antibody profile and the effect it may have in treating COVID-19 infection.

Thymalfasin (thymosin alpha 1 or Ta1), the active pharmaceutical ingredient in ZADAXIN® injection, is a 28-amino acid synthetic peptide, identical to natural Ta1 produced by the thymus gland. Ta1 is a biological response modifier which activates various cells of the immune system, and is therefore expected to have clinical benefits in disorders where immune responses are impaired or ineffective, including acute and chronic viral and bacterial infections, cancers, and vaccine non-responsiveness. Patients with end-stage renal disease (ESRD) on hemodialysis, in addition to their intrinsic kidney disease and frequent burden of comorbidities, also have increased risk of exposure to communicable diseases as they are treated several times each week at hemodialysis centers with several other patients and clinic staff in attendance. The majority of patients are over 60 years of age and many are receiving immunosuppressive medications. Accordingly, ESRD patients are particularly susceptible to COVID-19 infection. Ta1 has been shown to be safely administered to hemodialysis patients. It is our hypothesis that a course of Ta1 administered to individuals with ESRD will reduce the rate and severity of infection with COVID-19.

Background: SARS-CoV-2 is the virus that causes COVID-19. Some people who recover from COVID-19 have long-term symptoms that affect the brain. These include headaches; loss of taste and smell; sleep problems; thinking problems; depression; and anxiety. Researchers want to know if a tracer (a substance that is injected into a person s body before an imaging scan) can help identify inflammation in people with these brain disorders. Objective: To see if a radioactive tracer ([11C]PS13) can highlight brain inflammation in those who had COVID-19 but still have symptoms that affect the brain. Eligibility: Adults aged 18 to 70 years with post COVID-19 brain disorders who are enrolled in protocol 000089 or 000711. Healthy volunteers are also needed. Design: Participants will have up to 5 clinic visits. Participants will be screened. They will have blood tests and a test of their heart function. They will have imaging scans: Magnetic resonance imaging (MRI): They will lie on a table that slides into a metal tube. Pictures will be taken of the brain. Positron emission tomography (PET): A needle attached to a thin tube will be inserted into a vein in the arm. The tracer will be injected through the tube. Another needle attached to a thin tube will be inserted into the wrist or inside of the elbow of the other arm to draw blood. They will lie still on a bed while a machine captures images of their brain. The scan will last about 2 hours. Study involvement is 11 to 14 weeks....

The Long-Covid (LC)-Revitalize clinical study is testing repurposed drug treatments for Long Covid, involving adult participants from Brazil, Canada, Italy, Uganda, the United States, and Zambia. To qualify, participants must have had Covid-19 and experienced Long Covid symptoms for at least three months. The main goal of the study is to determine whether the drug treatments can improve symptoms in five key areas: 1) fatigue, 2) breathing, 3) memory, thinking, and communication, 4) muscle and joint pain, and 5) circulation. A secondary goal is to assess changes in the body, such as reducing inflammation, as well as to confirm the safety and tolerability of the treatments. In the first phase, 348 participants will take either one of two existing medications (upadacitinib or pirfenidone) or a placebo (a pill with no active ingredient) for three months. Although these medications are not yet approved for Long Covid, they are authorized for use in treating other health conditions. This study is adaptive, meaning it may adjust based on early results. In the second phase, the study could continue testing the most effective drug(s) against a placebo with new participants, explore combinations of drugs to see if they improve results, or discontinue the drugs if they prove ineffective or unsafe and test alternative treatments.

Novel coronavirus 2019 (COVID-19) has emerged as a major international public health concern. While much of the morbidity and mortality associated with COVID-19 has been attributed to acute respiratory distress syndrome (ARDS) or end-organ failure, emerging data suggest that disorders of coagulation, in particular hypercoagulability and venous thromboembolism (VTE), may represent an additional major, and possibly preventable, complication (Wu C, et al. JAMA Intern Med. 2020 Mar 13. [Epub ahead of print] and Tang N, et al. Thromb. Haemost. 2020 Feb 19. [EPub Ahead of Print]). Abnormal coagulation testing results, especially markedly elevated D-dimer and FDP, have been associated with a poor prognosis in COVID-19 infection. We propose the following Electronic Health Record (EHR)-guided 10000-patient, retrospective observational cohort study to assess VTE incidence, risk factors, prevention and management patterns, and thrombotic outcomes in patients with COVID-19 infection. In order to gain the valuable perspective of other regional and national centers providing care for large populations of COVID-19, we have started a collaborative network with 5 additional sites which will provide us with de-identified data from 1000 patients each. These 5000 patients in addition to the 5000-patient cohort we are enrolling within the Mass General Brigham Network will comprise this study population.
