Active clinical trials for "COVID-19"

THE EFFECT OF LIFESTYLE ON THE PROGRESS OF COVID 19 INFECTION The development of COVID 19 disease depends on the interaction with the immunity of the host. The immune response of the host is related to age, gender, nutrition, sleep and physical activity. Our study in Fatih Sultan Mehmet Training and Research Hospital; Between 31 January-31 May 2021,positive COVID 19 PCR test was performed with 66 patients over the age of 50, who received inpatient treatment. Demographic data of the patients, length of hospitalization, alcohol/tobacco use, BMI, comorbidities, regular use medication or not, thorax CT findings, place of discharge after treatment, laboratory parameters were recorded at hospitalization and discharge. To evaluate the pre-infection lifestyle; physical activity, nutrition and sleep habits were questioned. According to the PSQS (Pittsburg Sleep Quality Scale) although the increase in discharged lymphocyte measurements compared to the first hospitalization of the patients in the good and bad sleep groups was significant, there was no significant difference between the groups. In the evaluation between the groups, the increase in the NLR value at the first hospitalization was significant in the bad sleep group compared to the good sleep group. There was no difference between the groups in terms of NLR. According to the MNA(Mini Nutritional Assessment)scale ;the increase in the discharge lymphocyte value of the groups compared to the value at the first hospitalization was significant. The increases in the discharge lymphocyte measurements of the patients compared to the first hospitalization were significant between the groups (p<0.05). The increase in discharge lymphocyte values in patients at risk of malnutrition compared to the first hospitalization was higher than in patients with malnutrition (p<0.05). The decrease in discharge NLR values compared to the first hospitalization was significant in the group under normal nutrition and malnutrition risk. The difference between the first hospitalization PLT (Platelet)measurements of the groups according to the MNA scale was significant. According to the International Brief Physical Activity Survey; the increase in the discharge lymphocyte value of the inactive, minimally active and very active groups was significant compared to the first hospitalization. A significant difference was found between the PLT measurements between the groups (p<0.05). PLT measurements of very active cases were higher than those of minimally active cases (p<0.05). In this study, in which we examined the effects of lifestyle before the diagnosis of COVID 19 on the course of COVID 19, we observed that there is no need for intensive care in patients who are well fed, have good sleep quality and are physically active.

This quasi-experimental study aims to evaluate the efficacy and safety of pulmonary rehabilitation in post-COVID-19 patients and compare differences in primary outcomes before and after pulmonary rehabilitation. Its main aim is to provide an answer to the following question: What are the outcomes of pulmonary rehabilitation in post-COVID-19 patients in a tertiary care facility in Bangladesh? The participants will participate in 06 weeks of comprehensive multimodal and multidisciplinary outpatient pulmonary rehabilitation, including endurance training, strength training, patient education, relaxation techniques, psychological support, and nutritional counseling.

This is a dose exploration study to evaluate the safety and pharmacokinetics (PK) of AZD3152 in healthy adult male and female participants, across different dose levels and routes of administration (ie, Intramuscular [IM] injection and Intravenous [IV] infusion).

Flonoltinib Maleate as a JAK/FLT3 dual target inhibitor, previous pharmacological experiments showed that the IC50 inhibition of JAK2 kinase was as low as 0.8 nM, while the IC50 inhibition of JAK1, JAK3 and TYK2 kinases was 26 nM, 39 nM and 2 nM, respectively, and the IC50 of FLT3 kinase was 15 nM. It has high inhibitory activity for JAK2 kinase and good selectivity for JAK family.Multiple pharmacodynamic models evaluating the anti-inflammatory effect of Flonoltinib Maleate showed that Flonoltinib Maleate showed better therapeutic effect than the clinical drug Ruxolitinib with lower toxicity.

Acute and chronic cardiovascular complications of pneumonia are common and result from various mechanisms, including relative ischemia, systemic inflammation, and pathogen-mediated injury. However, there is only limited published data regarding on cardiovascular desease (CV) submissions in the wake of viral outbreaks. Data collected during the COVID-19 pandemic highlighted a number of possible determinants of adverse outcome in these patients, particularly with reference to cardio-respiratory complications.

This study will examine if the use of a smartphone application called Thrive4Life Connect can help people who use drugs lower their risk of overdose and learn more about COVID-19 vaccines. 60 participants will be enrolled and can expect to be on study for up to 6 months.

To verify the hypothesis that infertility and the effect of SARS-CoV-2 on infertility may damage platelet mitochondrial bioenergetics and endogenous coenzyme Q10 levels in infertile men.

The pandemic caused by the novel coronavirus SARS-CoV-2 has resulted in substantial global morbidity and mortality including in Oklahoma and caused unprecedented interruptions in nearly all aspects of our lives. The population of the state of Oklahoma is at particular risk to SARS-CoV-2 due to its large rural population, strained healthcare system, and poor overall health. The Community-Engaged Approaches to Testing in Community and Healthcare Settings for Underserved Populations (CATCH-UP) program will involve both practice-based and community-based approaches to maximize the reach of the RADx-UP consortium, broaden the potential perspectives that could be captured, and compare the effectiveness of strategies. The interventions will be pragmatic to allow CATCH-UP to respond to changing attitudes, barriers, and environments as the pandemic progresses as well as expected technology developments to produce more effective viral testing that can provide rapid results to patients. The investigators will assist 50 small primary care practices to implement guidelines-based testing and patient education about COVID-19 and risk mitigation strategies. The project's community-based approach is designed to rapidly respond to community testing needs by deploying mobile testing sites that will provide operational support to increase the efficiency and the existing capacity for state-wide testing by Oklahoma's public health authorities. Together, the investigators estimate that the CATCH-UP program will result in at least 105,000 SARS-CoV-2 tests performed during the first year of implementation. A comprehensive, ongoing evaluation will be performed to analyze patient and provider attitudes, barriers and facilitators of viral testing, identified health disparities caused by COVID-19, effectiveness of the intervention in both settings, and to allow robust collaboration with other RADx-UP consortium sites.

The outbreak of the novel coronavirus (SARS-CoV-2)-infected disease (COVID-19) began in December 2019, spread throughout China in early 2020 and developed as a pandemic thereafter. Based on current knowledge, Covid-19 infection causes mild to moderate respiratory and gastrointestinal symptoms in the majority of patients. In a smaller percentage severe disease courses are observed, often with the need of hospitalization and intensive care treatment. Apparently, symptoms can persist for relatively long time after viral clearance, suggesting the existence of a "Post-Covid" syndrome. A study from the UK identified fatigue, breathlessness and psychosocial stress as common symptoms after discharge from the hospital. Covid-19 infection is frequently characterized by a hyperinflammatory phenotype and a cytokine storm. The Covid-19 cytokine storm is characterised by rapid proliferation and hyperactivation of T cells, macrophages, mast cells, neutrophil granulocytes and natural killer cells, and the overproduction of inflammatory cytokines and chemical mediators released by immune or nonimmune cells. Early data also suggest that even if symptoms are just 'mild to moderate' during the acute infection, fibrotic lung damage develops in some patients. This may lead to long-term pulmonary complications for a subset of patients. The mechanisms for post-Covid pulmonary fibrosis are still unclear: inflammation triggering fibrosis, epithelial and endothelial injury with inadequate fibroproliferation and vascular damage are considered to be possible mechanisms. A potential therapeutic target in ameliorating post-Covid symptoms could be the gut microbiome. Gut microbiome alterations have been described in Covid-19. The gut-lung axis as a link between dysbiosis, barrier dysfunction, translocation of bacterial products and hyperinflammation has been proposed as a potential therapeutic target. Probiotics have been proposed to be a possible modulator of the deranged gut-lung axis in Covid-disease and post-Covid syndrome. Currently 11 studies are registered in clinicaltrials.gov for treatment of acute Covid disease and prevention of the disease (including one study from Graz), but no study related to post-Covid syndrome could be found. Therefore, it is currently unclear, which clinical, immune system or microbiome related biomarker would be the best to study the effect of a microbiome-based intervention in post-Covid syndrome.

COVID-19 is associated with increased mortality, and has been linked to a 'cytokine inflammatory storm'. Populations at higher risk of COVID complications and mortality include the elderly, diabetic patients and immunocompromised patients (such as HIV), and the investigators have studied these 3 populations over the past 20 years and have found that they all have deficiency of the endogenous antioxidant protein glutathione (GSH), elevated oxidative stress, inflammation, impaired mitochondrial function, immune dysfunction, and endothelial dysfunction. It is known and established that GSH adequacy is necessary for neutralizing harmful oxidative stress, and that elevated oxidative stress appears to promote mitochondrial dysfunction. The combination of oxidative stress and mitochondrial dysfunction have also been linked to inflammation, immune dysfunction, and endothelial dysfunction. In prior studies in aging, the investigators have also identified that supplementing glutathione precursor amino-acids glycine and cysteine (provided as N-acetylcysteine) improves GSH deficiency and mitochondrial function, and lowers oxidative stress, inflammation, and endothelial dysfunction. The investigators have coined the term GlyNAC to refer to the combination of glycine and N-acetylcysteine. This study will evaluate the prevalence and extent of these defects in patients with COVID-19 admitted to the hospital, and the response to supplementing GlyNAC or placebo for 2-weeks. Because patients with COVID-19 are also being reported to have fatigue and cognitive impairment, the investigators will also measure fatigue and cognition at admission, 1-week and 2-weeks after beginning supplementation. The supplementation is stopped after completing 2-weeks, and these outcomes will be measured again after 4-weeks and 8-weeks after stopping supplementation.
