Active clinical trials for "COVID-19"

Multicentre, retrospective, observational study to describe the course of SARS-CoV-2 disease in patients treated or not with IMUNO TF ® and a combination of nutraceuticals and who have tested positive in a COVID-19 diagnostic test based on the duration of symptoms.

The main purpose is to study the prevalence of Covid-19 in EHPAD. The primary endpoint will be the combination of PCR results and symptomatology, making it possible to define positive cases in EHPAD, in residents and professionals in contact with them. The prevalence obtained can be compared with the results of serology if these are performed.

The COVID-19 Prevention Network (CoVPN) is doing a study to estimate the number of people who have or have had the SARS-CoV-2 virus in different communities in the United States. This study is being done to help determine the best places to perform future research studies that will test new drugs for treatment or prevention of COVID-19.

COVID-19 infection causes a hypersensitive immune reaction and widespread inflammation through cytokines in various organs of the body, especially the lungs. This cytokine-mediated widespread inflammation can also affect the thyroid gland, causing thyroiditis and impaired thyroid functions. The researchers evaluated thyroid function tests and thyroid autoantibodies in patients hospitalized for COVID-19 infection. Researchers excluded patients on intensive care therapy and patients with known thyroid disease. The researchers examined the relationship of thyroid hormones and thyroid autoantibodies to COVID-19 disease, white blood cells, neutrophil / lymphocyte ratio, c reactive protein, fibrinogen, procalcitonin, ferritin, and D-dimer stages in these patients. Researchers compared changes in thyroid hormones and autoantibodies in people without COVID-19 infection and without thyroid disease.

To present the first admission chest computed tomography (CT) findings of patients followed up with a diagnosis of COVID-19, and to compare the two classification systems by evaluating these findings according to the BSTI and RSNA guidelines.

The main objective of this project is: 1. To assess the impact of COVID-19 on the brain and executive functioning. Twenty adult subjects of UZ Brussels (volunteers), who needed intensive care due to COVID-19 (n=10) or exhibited mild symptoms due to COVID-19 (n=10), will be recruited after hospital discharge. After signing an informed consent the subjects will undergo brain scans (T1, DTI, SWI, DWI, FLAIR MRI and rsfMRI), an emotion regulation task and a neurocognitive test battery. The latter test battery will be performed using an iPad and will test different neurocognitive functions such as memory, abstract thinking, spatial orientation and attention. The duration of the test battery is 18min. The total duration of one trial is estimated at one hour and a half. All tests are planned at the department of Radiology-Magnetic Resonance (UZ Brussel). After three months patients will visit the department of Radiology-Magnetic Resonance a second time for the same experimental trial. Additionally, a matched control group (n = 20; non covid or ICU patients) will be included and undergo the same tests in order to compare the results of the brain scans, emotional regulation task and neurocognitive test battery with results of both Covid-groups. Next to objective data, questionnaires will be filled out, i.e. visual analogue scales of mental and physical fatigue, Profile of Mood States and some additional return to work questions.

The ongoing coronavirus disease 2019 (COVID-19) which started in China, was declared on the 11th of March as a global pandemic 2020 by the World Health Organization (WHO). Governments around the world have introduced differing forms of lock downs since the start of the pandemic demanding citizens to confine to their homes and go out only in necessity to minimize exposure to the virus. The response was observed in the emergency departments and the number of patients who presented for non-Covid issues drastically reduced. Hospitals activated their mass casualty management plans and have reorganized and overstretched their capacity to be able to absorb both the influx of patients with the virus and those with other conditions. Part of that reorganization was reducing the surgical activity. The main focus was shifted to patients who are considered urgent and elective surgery were postponed. Hence only surgical emergencies were maintained. Many did not present to the emergency department for fear to contract the virus and from a sense of national and global solidarity against that pandemic. Whereas these measures are essential to prevent the spread of the virus, it may be hypothesized that for non-Covid issues, including surgical emergencies, patients may present late to the emergency department due to fear of contracting the infection in hospital. This would delay their management and lead to a worsened symptomology on presentation requiring a more complex surgical intervention with an increased complication profile. The investigators present initial data from four major hospitals in Belgium, characterizing surgical emergencies that were managed since the start of the pandemic and discuss the repercussion the pandemic has on management of urgent surgical patients and most likely evolution of surgery after the pandemic.

This non-interventional, biospecimen collection study is designed to help us better understand whether MS patients have impaired immune defenses to COVID-19 infection. The potential influence of immune modulating medications for MS will be considered through these exploratory studies. This study is also designed to provide context for interpretation of anti-SARS CoV2 serologies in MS patients during convalescence from COVID-19 infection.

Loss of smell is very frequently found in Europe during Covid-19 attack. This symptom was not initially expected as part of the classic symptomatology. This loss of smell mainly concerns patients with few or no symptoms, without criteria of severity and usually treated on an outpatient basis. As a result, given the unexpected occurrence of this symptom (with less awareness in the general and medical population) and the potential risk of contamination of Covid+ and anosmic subjects (due to their less symptomatic form), it is interesting to be able to propose large-scale screening for loss of sense of smell in order to preferentially direct subjects diagnosed as anosmic towards RT-PCR-type screening. In the medium term, the loss of smell seems to persist after the infectious phase, with delayed or persistent recovery, which can lead to negative psychological repercussions. The objective is to propose large-scale screening of the general population for loss of sense of smell during a pandemic period, in order to facilitate diagnostic orientation of the population. The diagnosis of loss of smell will be carried out using a simple olfactory test in the form of an olfactory stick to be smelled.

Since the beginning of the COVID-19 outbreak in France, nursing homes (NH) have been heavily affected. In this study, the investigators want to evaluate the factors associated with the occurrence of COVID-19 epidemic clusters within the nursing homes in the French Alps
