Active clinical trials for "COVID-19"

The global coronavirus pandemic has infected nearly 659 million people and killed more than 6.6 million in the past three years. The symptoms of in-hospital recovery are long and difficult after epidemiological infection of 2019-NCo5. 76% of the 1,733 discharged patients in Wuhan in 2020 still had at least one symptom of discomfort 6 months after infection, with fatigue or muscle weakness being the most common (63%). Foreign Research: In the United States, 15 percent of 16,091 people infected with COVID-19 in 2021 had symptoms that persisted two months after infection. Novel Coronavirus Infection Diagnosis and Treatment Protocol (Trial 10th Edition) For patients recovering from novel coronavirus infection, TCM syndrome differentiation can be carried out according to the Guidelines for Home-based TCM Intervention for Patients Infected with Novel Coronavirus, and appropriate TCM prescriptions should be given for intervention.

According to the WHO, contact tracing - along with robust testing, isolation, and care of cases is a key strategy for interrupting chains of transmission of SARS-CoV-2 and reducing mortality associated with COVID-19. Contact tracing, however, has a number of challenges. These include incomplete identification of contacts, inefficiencies in paper-based reporting systems, complex data management requirements, and delays in the identification of contacts and testing of contacts. In many settings, contact tracing has proven to be too resource-intensive to implement at scale, especially with higher levels of community transmission, highlighting the need for more efficient contact tracing approaches. Digital tools afford the possibility of strengthening contact tracing for COVID-19, in a more efficient way. However, there is limited evidence of the effectiveness and impact of these tools in the COVID-19 response, including contact tracing. This study proposes to compare the cascade of care between two strategies for COVID-19 contact tracing of SARS-CoV-2 infected index patients in Cameroon. In one strategy (intervention), the health facilities and health district testing units will implement contact tracing using a digital tool developed to support the tracing and testing of contacts (addition of a digital contact tracing module to the main platform for COVID-19 testing in Cameroon (Mamal Pro app)). This strategy will be compared to the standard contact tracing process (control), based on the current routine approach (use of the Mamal Pro application without the digital contact tracing module).

The objective of this trial is to compare the immunogenicity and the safety of the Beta-variant recombinant protein booster vaccine (VidPrevtyn® Beta, Sanofi) to a bivalent mRNA vaccine (Comirnaty Original/Omicron BA.4-5, BioNTech-Pfizer) in adults previously vaccinated with at least 3 doses of COVID-19 mRNA vaccine. The results will provide important data for the future COVID 19 vaccine strategy. A biobank will also be set up to evaluate the protection conferred by one or other of these vaccines as booster in the event of the emergence of new variants in the future.

COVID-19 infection was identified in Wuhan, China at the end of 2019 and turned into a pandemic in a short time. In our country, the pandemic continues at full speed and patients are being treated in various clinical pictures. In its clinical classification, the World Health Organization (WHO) divides COVID-19 disease into four stages: mild symptomatic disease, pneumonia, severe pneumonia, acute respiratory distress syndrome (ARDS), sepsis and advanced stage with septic shock. Case reports and cross-sectional studies report a list of more than 200 different symptoms in the development of post COVID-19 syndrome. Shortness of breath, persistent smell and taste disturbances, fatigue and neuropsychological symptoms (headache, memory loss, slowed thinking, anxiety, depression and sleep disturbances) are the most commonly reported symptoms. Musculoskeletal symptoms such as pain (myalgia), muscle weakness, arthralgia and fatigue are also common. Exercise endurance tests are used to predict the prognosis of the disease in chronic lung diseases, to determine functional exercise capacity, to evaluate the response of the disease to treatment and to interpret the results of clinical trials. Covid-19-induced lung infections and long periods of isolation may have negative effects on respiratory muscle strength, pulmonary function values and physical activity level. It has been reported that only one week of bed rest can cause serious muscle loss of up to 20%. Covid-19 infection increases the likelihood of asthma-like symptoms. In some cases, pneumonia and increased dyspnea are also seen. When volleyball players with Covid-19 infection were examined, respiratory muscle strength and fev1/fvc values were lower than expected. When looking at the interaction between infections and sleep, it was observed that different infections had different effects on sleep, with some infections increasing the amount of sleep while others decreased it. The increase in inflammatory mediators associated with systemic infection is thought to increase the amount of REM sleep and total sleep duration, perhaps in an effort to conserve energy and counteract infection. Some infections have a negative effect on the immune system, reducing the amount of sleep. Covid infection is also thought to have negative effects on sleep. The symptoms of COVID-19 in the chronic phase can further negatively affect physiological, psychological and social outcomes, physical activity and ultimately muscle performance and quality. Post-infection physical function and fitness can worsen even two years after the disease. In COVID-19 patients recovering 3 months after hospital discharge, limitations were mainly related to reduced muscle mass, low oxidative capacity or both, rather than cardiac or respiratory exercise limitation. Symptoms experienced during Covid-19 infection are thought to have negative effects on exercise endurance. In order to meet the metabolic needs of the musculoskeletal system muscles during exercise, cardiac output, ventilation, pulmonary and systemic blood flow, oxygen and carbon dioxide exchange in a way to maintain acid-base balance and oxygenation, and their compatible response to each other are required. Exercise endurance assessments are an important parameter to determine the functional level of the patient. Eighty-eight percent of individuals with Covid-19 infection showed a decrease in respiratory muscle strength in the evaluation performed 5 months later. The direct effect of respiratory muscles may cause permanent dyspnea problems. Muscle strength, exercise capacity, dyspnea perception, fatigue severity perception, pain, balance, kinesiophobia, psychosocial and cognitive status, quality of life should be routinely evaluated in the post-COVID-19 period in patients admitted to the clinic, and a targeted functional rehabilitation program should be prepared in the light of these evaluations, taking these parameters into consideration during the rehabilitation process.

This is a Phase II, randomized, double-blind, multi-centre trial to evaluate the safety and immunogenicity of BIMERVAX® when coadministered with seasonal surface antigen inactivated adjuvanted influenza vaccine (SIIV) in adults older than 65 years of age fully vaccinated against COVID-19. In this study approximately 300 adults aged 65 or older will be enrolled and followed for 1 month after study treatment. Safety and immunogenicity of all participants will be assessed.

Background: The indirect effects of the COVID-19 pandemic on mental health are of increasing concern. Perceived stress can lead to binge eating and weight gain. Researchers want to learn more about the relationship between eating behavior and the pandemic. Objective: To study how the stress of the COVID-19 pandemic is affecting eating behaviors and weight. Eligibility: English-speaking adults ages 18 and older who have access to a computer or smartphone connected to the internet. Design: This is an online study. Participants will answer surveys through the study website. Participants will complete a one-time survey. It will ask about their experiences throughout the COVID-19 pandemic, their socioeconomic standing, their mental and physical health, and their eating habits. They will have the option to repeat the survey once a month for the next 12 months. This will show changes in their thoughts and behaviors over time. They will provide their email address to get survey links. Participants will also have the option to complete a 2-minute survey on their smartphone. They will complete the survey daily for 7 days in a row. It will ask about their stress and eating behavior in real time, in their home environment. They will provide their phone number to get survey links via text message. If a participant has taken part in a previous NIH study on the Phoenix AZ campus, they will be asked to share their first and last name, date of birth, and email address. This information will be used to connect data from this study to their past data. Participation is typically 25 minutes but may last up to 1 year. ***To participate in this study go to the REDCap study link: https://redcap.link/nihcovidstudy.***...

This study is a randomized, double-blinded, and placebo controlled phase III clinical trial of the SARS-CoV-2 inactivated vaccine manufactured by Sinovac Research & Development Co., Ltd. The purpose of this study is to evaluate the efficacy, safety and immunogenicity of the experimental vaccine in healthy adults aged 18~59 Years.

No additional risk factors have been identified in patients with Inherited Metabolic Diseases (IMD) for contracting or presenting complications of COVID-19 compared to the general population. Yet, IMD patients have cell/tissue alterations that could constitute a potential direct or indirect target for the virus. We do not know the impact of this infection on patients suffering from MHM, nor the possible effect of specific treatment of MHM on the evolution of COVID-19. This study will collect French IMD patients having or having had COVID-19 infection. The main objective is to estimate among IMD patients contracting COVID-19 the frequency of disease aggravation or metabolic decompensation. The secondary objectives will be : a. to evaluate the incidence of COVID-19 diagnosed in a given group of IMD when the number of patients with this IMD is known (Urea Cycle Deficiency, Gaucher Disease). b. to evaluate the impact of IMD on the and severity of COVID-19 infection

Current data in the literature demonstrate that the immune response to CoV-2-SARS is much more complex than initially assumed. In fact, beyond the humoral response, including the existence of neutralizing CAs, the adaptive lymphocyte T-type immune response also appears to play an important role in controlling the infection and reducing the severity of the disease. At this stage, the analysis of this T response is still rudimentary and underdeveloped, but it seems crucial to be able to analyze it effectively in COVID-19 patients, which could help predict the evolution of the infection. It is also currently difficult to know the evolution of this response over time and especially after the resolution of the infection. To this end, we will analyze the T lymphocyte response (ELISPOT and QUANTIFERON) based on the secretion of IFN (Th1) and IL-4 (Th2) by CoV-2-SARS specific T cells from COVID-19 patients. We will compare the T response to the quality of the systemic and mucosal humoral response. Finally, we will evaluate in parallel two new biomarkers of the severity of COVID-19: plasma calprotectin and the presence of antibodies to type 1 IFN antibodies.
