Filter by:A Phase 2 multi-center, assessor-blind, randomized study to assess the safety, tolerability, and antiviral activity of brequinar in combination with dipyridamole.
Purpose of the study: to analyze the interlinks between serum 25(OH)D level and severity of new coronavirus infection (COVID-19) in hospitalized patients, as well as the effect of adding colecaciferol to standard therapy for patients in the acute period of the disease. The study will involve at least 300 hospitalized patients with confirmed COVID-19. All study participants will be twice assessed for serum 25 (OH) D levels: baseline and 8-10 days of hospitalization. Following a baseline examination, patients will be randomized into 2 groups. Group I (No. 1), vitamin D therapy begins with a dosage of 50,000 IU in the first and second weeks. Group II (No. 2), vitamin D therapy is prescribed at a dosage of 2000 IU / day. On 8-10 days of vitamin D supplementation, all participants will be retested for serum 25 (OH) D levels to assess the effectiveness of therapy. On 14-21 days we assessed severity of the course, ICU hospitalization, duration of hospitalization, outcome of the disease, duration of glucocorticoid therapy, the need for specific therapy (inhibitors IL-6), changes in cytokine/chemokine, APPs concentration.
Patients with Coronavirus Disease (COVID-19) experience distressing and challenging to manage respiratory symptoms. Interventions such as Oxygen (O2) therapy, oral opiates, and traditional nebulizers like ipratropium bromide and salbutamol, are variably effective, and therapeutic responses in individual patients are difficult to predict. The purpose of this study is to investigate the efficacy of nebulized fentanyl citrate on dyspnea, cough, and throat pain in patients with COVID-19, as well as evaluate the safety with any potential adverse events. In COVID-19, about 59% of patients will exhibit cough, 35% generalized body ache and sore throat and 31% will have dyspnea. Nebulized Lidocaine, magnesium, and opioids are alternative methods for the management of respiratory symptoms in various patients. Fentanyl nebulization was found to be effective in decreasing dyspnea in chronic obstructive pulmonary disease (COPD) patients by decreasing the rate of spontaneous respiratory rate, modulating cortical activity, and diminishing the brain stem chemoreceptor response to hypoxia and hypercarbia. The investigators hypothesize that nebulized fentanyl is superior to nebulized saline in suppressing cough, respiratory drive, improving breathlessness or dyspnea with the additional advantage of throat pain relief with minimal adverse effects in patients with COVID-19.
The present prospective cohort study aims to assess factors associated with of one-year health-related quality of life and physical, cognitive and mental health outcomes among adult survivors of hospitalization for COVID-19. Adult patients requiring hospitalization due to COVID-19 disease will be followed through structured and centralized telephone interviews performed at 3, 6, 9 and 12 months after enrollment.
This is a randomized, double-blinded, phase Ⅳ clinical trial of COVID-19 vaccine (Vero cell), Inactivated manufactured by Sinovac Life Sciences Co. , Ltd. The purpose of this study is to evaluate the safety and immunogenicity of booster vaccination using high-dosage or medium-dosage of COVID-19 vaccine (Vero cell), Inactivated in populations who have completed primary immunization 5-9 months
Background: Asthma is still considered a major chronic respiratory disease that affects a large number in the world. The association between COVID-19 infection and asthma was studied in different ways focusing on hospital admitted patients. This study aimed to evaluate the relation between asthma and COVID-19 infection in adults attending outpatient pulmonary clinic over three successive months from clinical and laboratory point of view. Patients and methods: The current study collected 1309 patients attending the outpatient pulmonary clinic of a Saudi Arabian private Hospital over three successive months from 1st of December 2020 to the end of February 2021. Patients were divided into three groups; Group 1: COVID-19 infected with asthma (312), Group 2: COVID-19 infected with no asthma (286) and Group 3: COVID-19 non-infected with asthma (300).
This is a randomized, Open, control phase Ⅳ clinical trial of inactivated COVID-19 vaccine manufactured by Sinovac Research & Development Co., Ltd,Beijing institute of Biological Products Co.,Ltd and Wuhan Institute of Biological Products Co.,Ltd.The purpose of this study is to explore booster Immunization of SARS-CoV-2 Inactivated Vaccine from different manufactures in adults aged 18-45 years old Previously Vaccinated with inactivated COVID-19 vaccine
Accuracy validation of the designed and manufactured ELISpot-based in vitro diagnostic 'Corona-T-test' for detection of SARS-CoV-2-specific T cells.
The purpose of this study is to test if visualizing the heart with cardiac MRI/echo will be important in the understanding cardiac function and prediction of cardiopulmonary symptoms, physical effort tolerance, and outcomes in COVID-19 survivors. If successful, the research will allow us to identify the causes of lasting cardiopulmonary symptoms and begin developing cardiac and lung directed therapies accordingly.
To evaluate the immunogenicity and safety of the third dose SARS-CoV-2 Vaccine, Inactivated (Vero Cell) in adults aged 18 years and above, who inoculated the third dose after 3, 4, 5, or 6 months since finished two doses schedule of Institute of Medical Biology Chinese Academy of Medical Sciences SARS-CoV-2 inactivated vaccine.
