NCT ID: NCT05694975 Recruiting - COVID-19 Pneumonia Clinical Trials

Efficacy of Megadose Vitamin C in Severe and Critical Ill COVID-19 Patients.

Start date: January 13, 2023
Phase: Phase 2/Phase 3
Study type: Interventional

The main aim is to determine whether vitamin C can reduce 28-day all-cause mortality or persistent organ dysfunction compared with placebo in patients with severe and critical ill COVID-19 patients. Participants will randomly receive HIVC or placebo for 4 days once enrolled. The primary outcome is a composite of death or persistent organ dysfunction (defined as dependency on vasopressors, mechanical ventilation, or CRRT) at day 28 after randomization.

NCT ID: NCT05692258 Recruiting - Acupuncture Clinical Trials

Acupuncture as an Adjunctive Therapy for Covid-19 Omicron Randomised Controlled Trial in Patients With Moderate/Severe Pneumonia

ZCFZZLXGBDFYHZ
Start date: January 6, 2023
Phase: N/A
Study type: Interventional

At present, China is facing the first wave of COVID-19 epidemic after the liberalization. The infection rate has exceeded 50% in most areas, and even exceeded 80% in some cities. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) belongs to the beta genus of coronavirus and enters cells mainly by binding angiotensin converting enzyme 2 (ACE-2) to the spike protein on the envelope. The Omicron strain is the main epidemic strain at present. The transmission ability of Omicron strain is stronger than Delta strain, but the pathogenicity is weakened. At present, the published articles on the adjuvant treatment of COVID-19 with acupuncture are mostly theoretical discussions or case reports, and randomized controlled trials on the observation of curative effect are rare. The purpose of this study is to clarify the effectiveness of the adjuvant treatment of COVID-19 with acupuncture. Providing high-level research evidence for them.

NCT ID: NCT05689008 Recruiting - COVID-19 Pneumonia Clinical Trials

UC-MSCs in the Treatment of Severe and Critical COVID-19 Patients With Refractory Hypoxia

Start date: January 10, 2023
Phase: Phase 3
Study type: Interventional

The goal of this randomized, controlled, open-labeled interventional clinical trial is to test the efficacy and safety of umbilical cord mesenchymal stem cells (UC- MSCs) in the treatment of severe and critical COVID-19 patients with refractory hypoxia even after sufficient standard treatment according to the tenth edition of Chinese guidelines for COVID-19 infection. The main questions it aims to answer are: 1. The efficacy of UC-MSCs in the treatment of severe and critical COVID-19 patients with refractory hypoxia. 2. The safety of UC-MSCs in the treatment of severe and critical COVID-19 patients. 3. The potential immune mechanisms of UC- MSCs in the treatment of severe and critical COVID-19 patients. Participants will receive standard therapy, or the UC-MSCs treatment. For the standard treatment, it will be conducted according the 10th edition of Chinese guidelines for severe or critical COVID-19 infection. For UC-MSCs treatment, participants will be given UC-MSCs instillation at the first and fourth day after assignment. Blood examples will be taken at indicated time for arterial blood gas analysis and other tests. And participants should also objectively report their symptoms change and other information related to the treatment as listed the research protocol.

NCT ID: NCT05687877 Recruiting - Clinical trials for SARS-CoV-2 Infection

Evusheld Japan PMS_Japan Post-Marketing Surveillance (PMS)

Start date: January 6, 2023
Phase:
Study type: Observational

To investigate intends to evaluate the incidence of adverse drug reactions (ADRs) in individuals who receive Evusheld in clinical practice to determine its post-marketing safety profile in Japanese.

NCT ID: NCT05684926 Recruiting - Asthma in Children Clinical Trials

COVID-19 Pandemic Asthma Child Telerehabilitation Yoga

Start date: November 1, 2022
Phase: N/A
Study type: Interventional

In our study, yoga asana and pranayama practices, which will be applied by video call from computer or phone, will be advantageous in terms of time, transportation and access to asthmatic children whose anxiety and anxiety levels increase during the COVID-19 period, whose access to hospital services is difficult, and whose physical activity level decreases due to the increase in screen time. It was aimed to examine the effects of these group exercises on Asthma Control, Functional Capacity, Physical Fitness, Physical Activity and Quality of Life. In the randomized controlled study, the treatment and control group will be determined by the closed envelope method, the control group will be placed on the waiting list and yoga will be practiced at the end of the study. The first and final evaluation will be done face to face in a clinical setting. The total duration will be 12 weeks, 3 days a week and 36 sessions between 8-8:40 in the evening. Researchers who will do yoga have a certificate of practice. Patients will be followed up in Hacettepe University Medical Faculty Asthma Allergy Clinic.

NCT ID: NCT05684887 Recruiting - COVID-19 Clinical Trials

Digital Tools to Expand COVID-19 Testing in Exposed Individuals in Cameroon

DTECT
Start date: October 18, 2022
Phase: N/A
Study type: Interventional

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).

NCT ID: NCT05682651 Recruiting - COVID-19 Clinical Trials

Relationship Between Post-Intubation Tracheal Stenosis and Covid-19

Start date: December 28, 2022
Phase:
Study type: Observational

Tracheal stenosis (TS) is a serious complication that occurs in approximately 6-22% of patients due to prolonged endotracheal intubation. Cuff hyperinflation of the endotracheal tube, use of large tubes, advanced age, female gender, smoking, obesity, and diabetes are risk factors for TS. The most common and serious complication in COVID-19 patients is acute respiratory distress syndrome (ARDS), which requires oxygen and ventilation treatments. In the literature, it is reported that 9.8-15.2% of patients need invasive mechanical ventilation (IMV). The concern of aerosol formation and prone position applications that emerged with the coronavirus pandemic caused delays in tracheostomy decisions and the use of uncontrolled high cuff pressures, paving the way for TS. The capillary perfusion pressure of the tracheal mucosa ranges from 20 to 30 mmHg. A cuff pressure of the endotracheal tube above 30 mmHg causes mucosal ischemia. Cartilage inflammation due to ischemic injury may be partial or full thickness. Depending on the degree of inflammation in the affected tracheal segments, stenosis and even perforation may develop. It is aimed to determine the etiological causes, to determine how much of the total TS cases covid-related TS constitutes, to examine the treatments and patient results in covid/non-covid TS. This study will contribute to the measures that can be taken during and after the care process in the intensive care unit.
