Active clinical trials for "Coronavirus Infections"

The aim of this work is to study the incidence of diaphragmatic dysfunction after COVID 19 infection and the efficacy of different types of diaphragmatic strengthening exercises on diaphragm muscle function.

The goal of this clinical trial is to examine the effectiveness of intranasal-administered Chlorpheniramine Maleate in COVID-19-positive participants as part of early treatment for COVID-19. The main questions it aims to answer are: To assess the efficacy of nasal spray with Chlorpheniramine (0.4%) for improving clinical recovery in COVID-19 patients. To assess the efficacy, safety, and tolerability of nasal spray with Chlorpheniramine (0.4%) as an adjunct to the standard of care in reducing hospitalizations and improving clinical recovery in adult patients with mild COVID-19.

The goal of this observational study was to explore the complex relationship between changes in the intestinal microbiome and serum metabolites in patients with novel coronavirus infection and acute pancreatitis. The main questions it aims to answer are: Question 1: The changes of intestinal microbiota and serum metabolites in patients with novel coronavirus infection and acute pancreatitis. Question 2: The relationship between the changes in the intestinal microbiome and serum metabolites. Participants will be recruited according to certain criteria. The investigators plan to recruit 4 groups of 30 volunteers, 120 volunteers in total. It is divided into (a) AP patients without COVID-19 (normal group) (b) AP patients with COVID-19 (treatment group) (c) patients with COVID-19 infection (control group) (d) normal healthy people. The basic information of subjects, including age, sex, address, and enrollment time, was collected after enrollment. After completing the relevant preparations, start the experiment. First of all, the sample collection and detection. Blood samples were taken from 2-3ml of blood (biochemical tube) after admission or in the morning of the next day, centrifuged at 3000 rpm for 3 minutes, and stored at -80℃ within 1 hour after taking the serum; Fecal samples are stool samples retained after admission and before antibiotic use. Fecal samples need to be stored at -20℃ within one hour after collection and transferred to -80℃within 24 hours. After the retention of samples, the retained stool samples shall be tested for bacterial flora, and the blood samples shall be tested for serum metabolomics. After the test, the investigators will use the statistical software SPSS 22.0 for statistical analysis. At the same time, in order to determine the correlation between intestinal flora and clinical parameters, the investigators will use Permutation analysis of variance (PERMANOVA) to process the data.

The treatment of the new coronavirus infection (COVID-19) and COVID-19-associated diarrhoea and liver injury remains challenging. Optimizing treatment approaches for COVID-19 remains an issue. It is assumed, that changes in composition of intestinal microbiota is closely related to a change in the regulation of the immune response in the lungs in patients with COVID-19. These gut microbiota changes in combination with antibiotic prescription during the treatment increase the risk of antibiotic-associated diarrhea and C. difficile infection as well as worse clinical outcomes in these patients. Probiotics are useful for restoring the human gut microbiome and increasing anti-inflammatory response also. Despite the variety of uses of probiotics, there is still insufficient data on the clinical efficacy of including probiotics in the treatment of patients with COVID-19 infection.

The purpose of this Phase III study is to confirm that SNG001 can accelerate the recovery of hospitalised patients receiving oxygen with confirmed Severe Acute Respiratory Syndrome coronavirus 2 (SARS-CoV-2). Safety and other efficacy endpoints will also be assessed.

Acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) are the most frequent complications of the COVID-19 pandemic. In these conditions, hypoxemia may result from : i) a pulmonary vascular dilatation resulting from an impaired hypoxic pulmonary vasoconstriction and leading to ventilation-perfusion mismatching within the lungs and ii) thrombosis-mediated perfusion defects. Pulmonary vascular dilation might be due to a relative failure of the physiological acute hypoxic pulmonary vasoconstriction, in the context of an over-activation of a regional vasodilatation cascade, as part of a dysfunctional inflammatory process. Perfusion abnormalities associated with pulmonary vascular dilation are suggestive of intrapulmonary shunting toward areas where gas exchange is impaired, ultimately leading to a worsening ventilation-perfusion mismatch, a regional hypoxia and a profound hypoxemia. Increased plasma levels of VEGF have been reported in moderate to severe COVID-19 pneumonia, highlighting the role of VEGF in the pathophysiology of the disease. A better prognosis has been reported in critically ill patients with lower levels of growth factors, HGF and VEGF-A at the time of ICU admission. Recent data of the study NCT 04275414 by Pang J et al have suggested that patients receiving a single-dose of bevacizumab have improved their oxygen support status in 92% of cases during a 28-day follow-up period, as compared with 62% of cases in an external cohort receiving standard care. Correcting endothelial permeability and vasodilatation with VEGF-targeted therapy could allow repair damaged vascular endothelium, have an indirect anti-inflammatory effect (limiting alveolar exudation of circulating inflammatory and procoagulant mediators) and improve oxygenation and therefore reduce the proportion of patients with severe forms requiring ICU referral and finally patient death. This clinical trial will therefore focus on the specific efficacy of bevacizumab in COVID-19 patients with severe hypoxemia.

To evaluate the safety and tolerability, the antiviral activity, and plasma pharmacokinetics (PK) of zotatifin administered intravenously (IV) to adults with mild or moderate COVID-19.

The renin-angiotensin system (RAS) has a relevant role in COVID-19, as the virus will enter host's cells via the angiotensin-converting enzyme 2 (ACE2); RAS disequilibrium might also play a key role in the modulation of the inflammatory response that characterizes the lung involvement. Angiotensin-(1-7) is a peptide that could be altered in COVID-19 patient and its supplementation may potentially helpful in this setting.

This is a randomized, double-blind, placebo-controlled trial to assess the efficacy of zinc in a higher risk COVID-19 positive outpatient population.

Coronavirus Disease 2019 (COVID-19) was first isolated in Wuhan, China in December 2019. It is rapidly spreading worldwide, posing a severe threat to global health. Many therapeutics have been investigated for the treatment of this disease with inconclusive outcomes. Anakinra - an interleukin (IL)-1 receptor antagonist - had showed survival benefits in patients with macrophage activation syndrome (MAS) and sepsis and was investigated for the use in COVID-19 infection with promising outcomes.
