Active clinical trials for "COVID-19"

Coronavirus Pathology is frequently associated with both diabetes mellitus and metabolic syndrome. In particular, results of observational studies and meta-analyzes configure diabetes as one of the main risk factors for the development of complications and unfavorable course of SARS (Severe Acute Respiratory Syndrome) and MERS (Middle East Respiratory Syndrome), the syndromes caused respectively by SARS- VOC coronavirus and MERS-COV coronavirus. The available data confirm this association also in the clinical picture of the infection supported by SARS-COV 2 (COVID-19). In the epidemic outbreak that erupted at the beginning of 2020 in the Lombardy Region, about two thirds of the patients who died from COVID-19 were affected by diabetes mellitus. COVID-19 occurs in 70% of cases with an inflammatory pathology of the airways that can be fed by a cytokine storm and result in severe respiratory failure (10% cases) and death (5%). At the moment, the mainly involved pathophysiological molecular mechanisms are not clearly defined. It has been hypothesized that the transmembrane glycoprotein type II CD26, known for the enzyme activity Dipeptilpeptidase 4 exerted by its extracellular domain, may play a fundamental role in this process. In addition, it is considerably expressed at the parenchyma and lung interstitium level and carries out both systemic and paracrine enzymatic activity, modulating the activity of various proinflammatory cytokines, growth factors and vasoactive peptides at the level of the deep respiratory tract. The pulmonary parenchyma and the interstitium express significantly the Dipeptilpeptidase 4 protein, which in the Middle East Respiratory Syndrome favors the entry of the virus into the cells, thus allowing the virus to replicate within the cells and thus spread throughout the cell inside the organism. Dipeptilpeptidase 4 regulates the function of bioactive peptides and above all of cytokines, vasoactive peptides and chemokines present at the level of the mesothelium, of the deep respiratory tract (alveolar epithelium and alveolar bronchus), of endothelial and immune cells triggering the inflammatory storm. In line with this evidence, it has been hypothesized that acute respiratory disease from Coronavirus may depend on the massive localization of Dipeptilpeptidase 4 in lung tissue. Furthermore, the involvement of Dipeptilpeptidase 4 in other chronic respiratory diseases has been demonstrated. Starting from these observations we hypothesized that the selective blockade of Dipeptilpeptidase 4 can favorably modulate the pulmonary inflammatory response in the subject affected by COVID-19. Among the drugs that selectively block Dipeptilpeptidase 4, the one with greater affinity precisely for Dipeptilpeptidase 4 is Sitagliptin.

The aim of this study is to investigate the levels of trauma and mental symptoms (i.e., depression and anxiety) among health workers and public service providers during the strict social distancing government-initiated non-pharmacological interventions (NPI's) related to the COVID-19 pandemic. The study also aims to investigate predictors of trauma-symptoms.

For preventing the overwhelming of ICU beds capacity during COVID-19 pandemic in France, national and regional Health-Care institutions decided to optimize the Intensive Care Unit beds availability by opening new ICU beds in institutions with and without prior ICU. The Present study was design to retrospectively describe the origin of the ICU beds and human resources created during the COVID-19 outbreak in France.

The COVID-19 pandemic is a traumatic event which could lead to a greater risk of developing post-traumatic stress disorder, especially in cancer patients who feel more at risk of contracting the virus, and fear developing serious symptoms. The study's primary objective is to measure the presence of a potential post-traumatic stress disorder in cancer patients, and to assess the associated factors. The secondary objectives are to measure patients' anxiety, as well as their perception of both the management of their cancer care, and their fear of a cancer recurrence. It is a prospective, multi-centric study using self-assessing survey offered to cancer patients currently under ongoing care or treatment. The surveys will be sent by post at the beginning of the study, and again 6 months later. Expecting a participation rate of 40%, 4000 patients will be contacted, over a period of 3 months, in order to receive 1600 responses, and 640 responses 6 months later. Researching the factors associated with the appearance of post-traumatic stress could lead to better screening of patient disorders in highly anxiety-provoking crisis situations. As a result, it would lead to an improvement of their care, healthcare organization, and their follow-up in the case of a new epidemic or any other stressful event of this magnitude. Furthermore, promoting the patient's expression capabilities favors their implication in their care, and facilitates the development of health democracy.

Ursodeoxycholic acid is a clinically approved drug which widely used in patients with chronic liver diseases, especially liver transplantation. In China, the COVID-19 infection is in an epidemic state, and the population is generally susceptible to COVID-19. More attention needs to be paid to the prevalence and severity of people taking immunosuppressants after organ transplantation. Recent cohort studies and experiments based on tissue cells, animals and human beings suggest that ursodeoxycholic acid has the potential ability to prevent the entry of COVID-19 into cells, revealing that Ursodeoxycholic acid may be used to prevent the COVID-19 infection. Based on the medical records of patients( already registered on the management website http://www.cltr.org or www.csrkt.org.cn) who received organ transplantation in the First Affiliated Hospital of Xi'an Jiaotong University and the First Affiliated Hospital of Zhengzhou University, this project intends to collect information and data from patients received organ transplantation, aim to understand the COVID-19 infection and severe condition of organ transplantation patients, also explore whether ursodeoxycholic acid has preventive and therapeutic effects on COVID-19 infection and severity rate in patients. This research provides a theoretical basis for further standardizing the prevention and treatment of COVID-19 in patients received organ transplantation.

The present study aims at assessing long-term hemostatic profile of patients recovered from COVID-19 acute infection that remain asymptomatic (POST-COVID) versus patients with residual symptoms (LONG-COVID) through the employment of a commercially available new generation point-of-care viscoelastic device. The primary endpoint is based upon the hypothesis that patients with residual symptoms maintain an abnormal coagulation profile even after recovery from COVID-19.

In 2021 and following the COVID-19 (corona virus disease 2019) pandemic, different vaccines were initially authorized in Italy and Lebanon. Notably, vaccine side effects were poorly recorded. Thus, the investigator performed a survey study to monitor COVID-19 vaccine side effects among Italian and Lebanese citizens according to gender and age through a web-based questionnaire in Italian and Arabic languages including 21 items by "Google Form", investigating 13 symptoms, and employing social-media platforms

The goal of this retrospective analysis is to compare the magnitude of improvement in respiratory and peripheral muscle strength, following the completion of a hybrid pulmonary rehabilitation programme, in men and women with long COVID-19 syndrome. The main question it aims to answer is the following: • does gender limits the effects of a hybrid pulmonary rehabilitation programme on respiratory and peripheral muscle strength?

Ice swimming is an increasingly common phenomenon in Poland. It has been confirmed that it has a beneficial effect on health by increasing the natural non-specific immunity to infections. In the face of the current Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) pandemic causing Coronavirus Disease 2019 (COVID-19), researchers decided to use a survey to check the incidence of COVID-19 among Polish ice swimmers, as well as recent ailments. Then, the researchers will compare the obtained results with epidemiological data for Poland.Researchers will also investigate the relationship between susceptibility to SARS-CoV-2 infection and the blood group and Rh factor among ice swimmers.

Coronavirus disease 2019 (COVID 19) is primarily a respiratory viral infection. At the time of writing this protocol, more than 25 million people have been affected globally. Of these, more than 850000 have died directly due to the disease. In the Kingdom of Saudi Arabia, there are as of now over 30000 cases and deaths from COVID 19. This has been declared as a Pandemic by WHO and has brought normal life to a standstill. There are many uncertainties regarding the pathophysiology and clinical course of this disease. It is estimated that 80 percent of those infected will not need special care. However, 1 in 5 (20%) patients will require hospitalization. Of these, typically, 5 percent will be critically ill and ventilated. Of those ventilated, 20 to 60 percent will die. However, this can vary from country to country due to various reasons. For example, in one study, 71.6% were hospitalized in the Kingdom of Saudi Arabia, and 4.6% were admitted to intensive care. The rest of those who are hospitalized (95%), are at risk of having long term sequelae. From the SARS CoV infection data, 50 per cent had changes consistent with inflammatory lung disease at 4 weeks, and at 15 years, 4.6% (SD 6.4%) had pulmonary fibrosis. Middle East Respiratory Syndrome (MERS) had typical lower lobe fibrotic changes in more than one-third of the patients. SARS CoV2 virus shares 79.5% sequence identity with SARS CoV and 50% with MERS CoV. The SARS CoV2 may also have similarities in the inflammatory response; emerging data shows that COVID 19 patients also have new interstitial lung disease changes and thromboembolic disease. These patients may have long term physiological disability such as exertional hypoxia, breathlessness, reduction in static and dynamic lung volumes and diffusion factors. There is currently no data available to predict who is at risk of developing long term chronic thromboembolic disease and interstitial lung disease. More importantly, there are no data available on the pathological changes of inflammatory lung disease. Pathologically classifying the disease may have a significant impact on the choice of the treatment for these patients who otherwise have the potential to be disabled lifelong. With appropriate phenotyping, appropriate risk reduction strategies and targeted therapies can be considered. Furthermore, studying biomarkers that could potentially identify those at-risk patients from very early on can provide an opportunity to start on the treatment very early on in the natural course of the disease history.
