Active clinical trials for "COVID-19"

In December 2019 the first case of human infection by a new coronavirus was identified, currently called SARS-COV-2 (Severe Acute Respiratory Syndrome - Coronavirus - 2), characterized by high contagiousness and the possibility of causing a severe acute respiratory distress syndrome from which its acronym derives and which caused the state of a global pandemic in a few months. The most frequent clinical manifestation of COVID-19 is pneumonia, which in about 20% of cases results in acute respiratory failure. Very few studies have so far addressed the problem of clinical and functional recovery in these patients, most of them just before or after discharge and none specifically focused on patients admitted for ARF. Indeed most of these investigations were limited to a specific field such as symptoms, pulmonary function and radiological changes. There are no guidelines for the follow-up of COVID-19 patients, despite the British Thoracic Society (BTS) has published a guidance for scheduling post-hospitalization assessments. Aim of this study is to describe the long term (6 to 12 months) evolution of lung involvement in patients discharged after an episode of ARF due to COVID-19, identifying possible factor associated to lasting clinical, functional or radiological abnormalities collecting data from hospital stay, 1-month after hospital discharge, 3-months after hospital discharge and 6-to-12-months after hospital discharge.

The Respiratory infection COVID-19, due to a new coronavirus, SARS-CoV2, appeared in December 2019 in several people who attended the wildlife market in Wuhan, Hubei Province, China. While COVID-19 has spread to nearly 200 countries and caused two millions infections, Lao PDR detected its first confirmed case very recently, on March 20, three months after the start of the outbreak in China. As of April 12th, 2020, Lao PDR has only recorded 18 confirmed cases, a very low number compared to other countries around the world. However, several key factors suggest that Lao PDR could be much more affected by COVID-19 because of the following reasons: (i) The multiple and massive trans-border movements between Lao PDR and China. (ii) The similar biogeographical and socio-ecological characteristics with South-Western China. (iii) The detection of a high diversity of Betacoronavirus sequences in several species of bats in Lao PDR. (iv) The numerous markets selling high volumes of local wildlife including bats and pangolins. LACOVISS project aim at investigating, using a ONE-HEALTH approach, this unexpected epidemiological pattern of SARS-CoV-2 in Lao PDR by bringing together an interdisciplinary team of experts in the field from IRD, the University of Caen, the Center of Infectiology Lao-Christophe Mérieux (CILM) and the National animal Health Laboratory (NAHL) in Vientiane. The study will focus on a community-based cohort of 1092 households, including 5400 study participants, followed-up between March 2015 and February 2019 for influenza-like illness investigation and causative agents detection (LACORIS project), located in the Vientiane metropolitan area. The COVID-19 progression in Lao PDR, and track SARS-CoV-2, will be followed retrospectively and prospectively, in all potential actors in SARS-CoV-2 circulation, including humans, domestic animals, and wildlife. The LACOVISS project will undoubtedly bring new insight in SARS-Cov-2 and SARS-CoV-like circulation in Lao PDR as well as valuable information on the natural history of COVID-19, and on the modalities of the spillover into humans, which are still largely unknown.

A descriptive, clinical series, single-centre, national, biomedical study to determine the presence of SARS-CoV-2 in sperm samples from positive PCR patients for COVID-19 and to evaluate the presence of the virus in the sperm samples after a negative PCR for COVID-19

This study will evaluate the associations between vascular parameters and clinical outcomes in patients hospitalized with COVID-19. The vascular function and structure of individuals with COVID-19 admitted to the General Hospital of the University of Sao Paulo will be assessed in the first 72 hours of hospitalization. Then, participants will be followed up until hospital discharge/death. Logistical regressions will be run to evaluate if vascular function/structure can predict ICU admissions, intubation, thrombosis or death.

This is a Russian multicenter observational study aimed to assess the mid-term and long-term prognosis in patients recovered from COVID-19 with the involvement of the cardiovascular system or with baseline severe cardiovascular diseases.

It was observed during the last period of COVID-19 pandemic that diabetic patients had a worse prognosis and more deteriorated clinical features than other patients

The aim of this study is to evaluate pro-inflammatory cytokines as well as microvesicles during the course of SARS-CoV2 infection in the context of clinical parameters.

To assess if TSLP expression by airway epithelial cells following COVID-19 infection regulates viral load and disease severity.

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is responsible for the coronavirus disease 2019 (COVID-19) pandemic challenging health systems worldwide. While there is a clear correlation between oxidative stress markers and the severity of many viral diseases such as hepatitis C, for SARS-CoV clinical data is limited. The investigators aim at 1.) investigating DNA damage, oxidative stress, inflammation, and aging markers in COVID-19 patients and compare them with age and gender matched healthy controls and patients with influenza; and 2.) investigating all aforementioned parameters during "cytokine storm" via repeated blood sampling.
