Active clinical trials for "COVID-19"

Background After the emergence of Covid-19 in China, Hubei Province, the epidemic quickly spread to Europe. France was quickly hit and the Croix-Rousse hospital at the Hospices Civils de Lyon was one of the first French university hospital to receive patients infected with Sars-COV2. The predicted massive influx of patients motivated the cancellation of all elective surgical procedures planned to free hospitalization beds and to free intensive care beds. Nevertheless, patients who had to be canceled had to be properly selected to avoid a life threatening. The retained surgical indications were surgical emergencies, oncologic surgery and organ transplantation. The objective was to describe the organization of the Croix-Rousse hospital to allow the continuation of these surgical activities while limiting the exposure of patients to the Sars Cov2.

It is unclear how COVID19 can be passed from mother to infant. The study investigators aim to collect maternal and neonatal samples from COVID19-infected pregnant women and compare them to pregnant women who have clinical indications for COVID 19 testing at the time of hospital admission but end up being COVID19 negative. Pregnant women who are either COVID19 positive or COVID19 negative with respiratory symptoms will be enrolled and followed during this study.

Investigators will recruit patients diagnosed with COVID-19 pneumonia between March 11th, 2020 and April 15th, 2020 in emergency, internal medicine and cardiology outpatient clinics, retrospectively and analyze their clinical and demographic features on admission in regard to their medications used for chronic diseases regularly.

The primary objective is to determine the usability of the SARS-CoV-2 Specimen Collection Materials for at-home collection and mailing of sample to the testing laboratory.

A retrospective case series of patients who self-medicated with Famotidine during coronavirus disease 2019 (COVID-19). The study will collect de-identified patient reported outcome measures of patients with confirmed COVID-19 who self-medicated with Famotidine at any dose during the period of illness. Data will be collected by questionnaire and telephone interview. Inclusion criteria: Age>18; Ability to give written informed consent for study participation; Confirmed diagnosis of COVID-19; Use of Famotidine at any dose during period of COVID-19 illness

Multicapillary Ion mobility spectrometry of nasal air aspirates shall be investigated as screening tool for the detection of Influenza and SARS-CoV-2- infection.

In Italy there are about 5000 patients with dependent transfusion thalassemia (source Italian Thalassemia and Hemoglobinopathies - SITE) and a smaller number, currently not definable, of patients with sickle cell anemia in chronic transfusion. A recent study in the Lombardy region identified the positivity of anti-Covid-19 antibodies in 4.5-7% of asymptomatic donors (Valenti L et al). As already known, a preliminary study conducted in Italy (Motta I et al, Hussain FA et al, Taher A et al) reported only 11 cases of symptomatic infection all with benign evolution. Currently there are 15 reported cases (12 thalassemias and 3 sickle cell anemias). 75% of the cases have been identified in Lombardy. Our hypothesis is that in a percentage of polytransfused patients a transmission of the virus may have developed that stimulated the production of protective antibodies. This could be an explanation of the low contagiousness and severity of the infection in polytransfused patients. Currently no data are available for this purpose. This study will be conducted in collaboration with the Microbiology Unit and involves the determination of SARS-CoV-2 antibodies (anti-s1 and s2) by CLIA method with a high sensitivity (94.7%) and specificity (98.5%).

The purpose of this case-control study is to assess the association of the current and former consumption of tobacco and nicotine in the risk of acquisition of severe acute respiratory syndrome 2 (SARS-CoV-2). the investigators will send a structured interview by mail regarding use of tobacco and nicotine to 2500 healthcare workers (1250 cases with a positive Real Time Polymorphism Chain Reaction (RT-PCR) and 1250 controls with a negative PCR) who were tested in Paris for in March and April, 2020. OR will be estimated by conditional logistic regression modelling with matching for sex and age.

The new type of Coronavirus (SARS-CoV-2) epidemic puts great pressure on health systems around the world. A large number of people are hospitalized in intensive care units due to acute respiratory distress syndrome due to SARS-CoV-2. Common symptoms seen with SARS-CoV-2 include fever, cough, and dyspnea, as well as pneumonia, severe acute respiratory distress syndrome, renal failure, and even death. Many patients develop mild to moderate disease without pneumonia. The respiratory condition of some patients continues to worsen gradually and develop acute respiratory distress syndrome, which usually requires mechanical ventilation support. Exercise capacity and health status of individuals who survived severe acute respiratory distress syndrome are lower than the general population. Persistent physical, cognitive, and psychosocial disorders can be seen in people who have survived acute respiratory distress syndrome. Given the clinical and radiological heterogeneity of COVID-19, it is important to have a simple tool for the disease to monitor the course of symptoms and the impact of symptoms on patients' functional status. Klok FA et al. developed the Post-COVID-19 Functional Status Scale (PCFS). PCFS can be evaluated for functional sequelae after discharge from the hospital, at 4 and 8 weeks after discharge, to directly monitor recovery, and at 6 months. The aim of this study is to investigate the validity and reliability of PCFS in Turkish population. Research permission to investigate the validity and reliability of PCFS in the Turkish population was obtained from the developer of the PCFS.

CT signs that are evocative of lung COVID-19 infections have been extensively described, whereas 18F-FDG-PET signs have not. Our current study aimed to identify specific COVID-19 18F-FDG-PET signs in patients that were (i) suspected to have a lung infection based on 18F-FDG-PET/CT recorded during the COVID-19 outbreak and (ii) whose COVID-19 diagnosis was definitely established or excluded by appropriate viral testing.
