NCT04958889
This observational study will prospectively characterize the long-term symptoms and side effects of COVID-19 in cohorts of people living with and without HIV. This will be achieved through a series of remote study visits involving completing surveys about health history, symptoms, mood, quality of life and changes in health, and up to two blood draws from home through the use of a mobile phlebotomy service.
NCT05996770
In this retrospective study, we aimed to evaluate the clinical efficacy and safety of two antiviral drugs on COVID-19 and inpatients with existing complications in the First Affiliated Hospital of Shandong First Medical University. In addition, we also explored a key issue. Is the combined treatment effect of two antiviral drugs, Paxlovid and Azvudine, better than the use of a single drug?
NCT05116748
Background: ISHLT and AASLD guidelines recommend SARS-CoV2 vaccination in all individuals undergoing lung and liver transplantation, but there are currently scarce data on the safety and efficacy of these vaccines in this population. In Italy, immunocompromised patients have received the indication to be administered mRNA vaccines only. Primary outcome: safety and reactogenicity Secondary outcomes: immunogenicity and prevention of COVID19 Visits and timepoints: * T0: before first dose administration: visit and venous sampling to assess baseline COVID19 serum status * Telephone calls to assess safety and reactogenicity 1 and 2 days after each dose of vaccination * T21 or 28 (based on vaccine; mRNA BNT162b2 and mRNA-1273, respectively): visit, venous sampling to assess immunogenicity * Follow up visits after 60, 120, 180 and 365 from T0: visit and venous sampling to assess immunogenicity
