Active clinical trials for "COVID-19"

The aim of the present work is to describe the hemodynamic effects shown in patients with ARDS secondary to SARS-CoV-2 infection

The recent Coronavirus Disease 2019 (COVID-19), has caused a global pandemic, and development of safe, effective vaccines is mandatory to return back to pre pandemic life. Many vaccines have been developed and requested by the authorities after the emergency license issued. The main mechanism of protection is through humoral and cell-mediated immune responses that might reduce the potential for disease development or severity. Cytotoxic T cells clear virus-infected host cells and contribute to control of infection. Preliminary data are now available indicating safty and effecacy of different vaccines . The vaccines were tolerated, with induction of neutralizing antibodies and antigen-specific T cells against the SARS-CoV-2 spike protein. The aim of this work is to evaluate the immune responses in adults, aged 25-65 years, up to 8 weeks after vaccination with a single and double doses live inactivated (Sinopharm), mRNA (Pfizer/ Biontech) and viral vector (Oxford/AZ- ChAdOx1 nCoV-19) vaccines. The Th1- response ( interferon-γ and tumor necrosis factor-α cytokine secretion by CD4+ T cells) and antibody production predominantly of IgG1 and IgG3 subclasses as well as CD8+ T cells mono, polyfunctional and cytotoxic phenotypes, will be also measured.

Pre-procedure and Short-Term COVID-19 Testing of Outpatients Undergoing Non-emergent Invasive Cardiovascular Procedures

The main objective of this part of the project is to identify the germline genetic factors which discriminate the benign and severe forms of SARS-CoV2 (CoVID-19) infection in the context of the ongoing SARS-CoV2 (HCOVID-19) epidemic. The scientific arguments of the project are described in APPENDIX. We hypothesize that pathogenic variants in genes coding for crucial factors involved in the HOST PATHOGEN interaction could explain the susceptibility of some patients to severe disease, even in the absence of comorbidities. The challenge is to identify those of the genetic factors who may be related respiratory distress and potentially further death. Based on our previous experience in sarcoidosis, a multifactorial disease predisposing to opportunistic infections, we will focus particularly the regulation of apoptosis and autophagy, immune response to viral infection, and endoplasmic reticulum stress response (ER STRESS) which is closely linked to apoptosis. Genetic defects in such pathways may decrease the clearance of viral particles and induces the progressive invasion by SARS-CoV2 and destruction of lung parenchyma. Our strategy will be similar to that described in our previous studies on sarcoidosis, recently published. We will combine a comparative genotype analysis by WHOLE EXOME SEQUENCING (WES) of benign and severe forms of SARS-CoV2 infection through clinical subgroups defined by the infectious diseases experts and a bioinformatics analysis of the functional networks identified by the panel of genes sharing pathogenic variants and discriminating the severe forms of the diseases. WES data will be carefully analyzed and related to all the intracellular physiological process and also the functional pathways involved in host-pathogen interaction: viral targets on the cell surface and downstream signaling, viral genomic RNA replication and translation, production and release of new viral particles. Finally, our main objectives are the definition of a gene panel more specifically related to severe forms of infection and the characterization of defective pathways involved in pejorative forms of SARS-COv2 disease in order to identify putative therapeutic targets.

Cancer patients are among the most vulnerable individuals, whose health-related quality of life (HRQOL) may be substantially impacted by the COVID19 pandemic. We want to study how the COVID-19 pandemic influences the life of cancer patients and how these patients cope with the additional distress with the aim to facilitate the development of improved future interventional strategies to maintain resilience and HRQOL

The aim of the regional online questionnaire is to better understand the pattern of acute infection and the time of recovery of various symptoms.

At the end of January 2020, the international community was informed of the presence of a new viral disease that started in Wuhan (China) and spread rapidly throughout the world. The identified virus belonged to the coronavirus family (SARS-CoV-2) and the disease was named COVID-19. Today there are more than 2 million people diagnosed in Spain and more than 40 thousand in Extremadura. The partial knowledge about the development, evolution of the affected citizenship and their prognosis both early and late makes it necessary to analyze in depth their global and particular characteristics. We will carry out a multicenter, observational, descriptive, cross-sectional and longitudinal study of patients diagnosed with SARS-CoV-2 virus infection in the Community of Extremadura to determine the effectiveness of drug treatments and the clinical and evolutionary characteristics of these patients and the different factors that may influence its evolution.

Evaluate effect of DAADs on covid-19 disease.

The primary objective of this study is to evaluate the current management approach with "intermediate" or "therapeutic" doses of tinzaparin for thromboprophylaxis in hospitalized patients, non on ICU organ support, with confirmed COVID-19.

Patients requiring admission to the hospital due to a moderate and severe COVID-19 infection may differ in their ability to respond to viral infection and to eliminate viral load. Several comorbidities and interventions like antivirotic or antiinflammatory treatment may also modify expected patients response and decrease of viral load. In this observational study, evolution of selected inflammatory markers, indicators of severity of infection and patient characteristics will be followed and recorded in hospitalized patients with COVID-19.
