Parental Compliance After Telephone Triage Advice During and After Confinement During the COVID-19 Epidemic in France

COVIDTEL
Start date: July 2021
Phase:
Study type: Observational [Patient Registry]

Novel Coronavirus disease 2019 (COVID-19) outbreak seriously challenges worldwide health care systems. The current climate of anxiety due to COVID-19 and home confinement limiting access to emergency departments (ED) have induced an increase of phone calls to the emergency call center "15" medical advices. To determine if a pediatric telephone triage protocol may improve patient's pathways during COVID-19 outbreak, parental compliance is assessed after telephone advice, during and after home confinement (the end of home confinement in France was on May 11th 2020). From 14th April 2020 to 7th June 2020, all calls received by the platform of telephone calls at Children's Lenval Hospital during open hours and open days are collected. For each call, symptoms are recorded by trained physicians and trained residents using a telephonic triage tool through a directed interview. A medical orientation is recommended to parents at the end of their call. Follow-up are conducted 2 to 4 days after with their consent by telephone interview in order to evaluate their compliance

COVID-19 And Geko Evaluation: The CAGE Study

CAGE
Start date: April 2022
Phase: N/A
Study type: Interventional

The primary objectives of this pilot study protocol are to assess safety and feasibility of using the geko™ device in COVID-19. Regarding safety to patients, we will measure the rate of adverse events, primarily local site irritation or discomfort. Feasibility will be measured on the basis of recruitment; ability to enroll sufficient number of patients meeting criteria. Protocol adherence will be observed as the ability to deliver the study intervention to the patients randomized to the treatment arm within the prescribed timeline and ability to complete the course of treatment. Additionally, we plan to measure patient outcomes such as ICU admission and death. The findings of this study have the potential to decrease the complications seen in COVID-19 infections.

NCT ID: NCT04643860 Withdrawn - Clinical trials for SARS-CoV-2 Infection Covid19

Differential Leucocyte Count and Covid-19 Diagnosis

Start date: January 15, 2021
Phase:
Study type: Observational

To date, the diagnosis of SARS-CoV-2 infection is made by identifying the viral RNA in samples collected through a nasopharyngeal swab or other respiratory samples but this technique, has several limitations for its application in a mass screening. Recently, it has been developed a new method of acquitting the occurrence of severe Sar-COV-2 infection, detecting the early rise in leukocyte levels which has a characteristic set of ratios of leukocyte types, which identify the pathogen. Primary aim of the Diagnostic Accuracy study is to validate the use of the point-of-care characteristic Differential Leucocyte Count (CLDC) device and algorithm to detect SARS-CoV-2 infection as a preliminary approach to a mass screening program. Secondary aims are to define if CLCD methods is able to detect SARS-CoV-2 infection earlier as compared to swab molecular testing. Subjects at low and high risk of Sar-Cov-2 infection will be tested, at the same time of the nasopharyngeal swab procedure in the morning, each recruited subject will be also tested using CLDC device and algorithm. On a voluntary base, subjects will also undergo blood drawing (3 ml) for hematological cytometric analyses, research personnel will administer a questionnaire on COVID 19 symptoms and risk factors and for contact traicing. Subjects testing positive on either CLDC test but negative at the swab will undergo on a voluntary basis new swab testing after two, 5 and possibly 8 days if still negative. It estimates to find between 150 and 200 positives in a population of 1000 subjects at different risk of infection.

Clinical and Immunological Evolution of Covid-19 Occurring in a Context of Non-Hodgkin Lymphoma

LYMPHO-Cov-2
Start date: November 1, 2020
Phase:
Study type: Observational

France was gradually affected by SARS-Cov-2 from January 2020; it evolved in an epidemic mode in March and April 20. During the 1st phase of the epidemic, more than 250 000 cases of Covid-19 have been confirmed in France resulting in the death of more than 30,000 patients. Mortality from infection varies greatly depending on the age of the affected individuals and their comorbidities including a history of cancer. We conducted a retrospective study in 89 patients with lymphoma and Covid-19 during the first phase of the epidemic and showed a 30-day mortality of 29%. Mortality was higher in patients over 70 years of age and in a situation of relapsed or refractory disease. Lymphoma-induced hypogammaglobulinemia and / or lymphopenia as well as chemotherapy and immunotherapy treatments are known to promote the development of infections in affected individuals. Among these, anti-CD20 monoclonal antibodies, widely prescribed to treat B-cell non-Hodgkin lymphomas (B-NHL) induce a rapid depletion of over 95% of mature CD20 + B cells. This can alter the production of antibodies, and the constitution of memory responses to a new pathogen. Also, B lymphocytes have a key immunomodulatory role in the control of viral infections. The specific immune response to SARS-CoV -2 and its evolution remain under characterization. Regardless of their neutralizing capacity, specific IgM appear 5 days after the onset of symptoms while IgG appear after 14 days. The immune response to SARS-CoV-2 also includes a T lymphocyte component, with an increase, among circulating lymphocytes, of activated CD8 and CD4 T lymphocytes. Data are still lacking on the specific response of CD4 and CD8 T lymphocytes against SARS-CoV-2, but these responses probably play a crucial role in virus clearance as well as in the immunopathology associated with SARS-CoV-2. Therapeutic depletion of B lymphocytes before acute infection may alter the generation of primary and functional responses. Therefore, a growing concern is whether patients with B-NHL who have acquired an infection with SARS-CoV-2 are protected against re-infection in the same way when they have or have not received anti-CD20 monoclonal antibodies. Analyzing the clinical and immunological evolution of Covid-19 in patients with B-NHL is useful to adapt the treatment recommendations in their regard according to the risk of severe form of Covid-19 . This is a multicenter, prospective study to determine whether treatment with monoclonal anti-CD20 antibodies in patients with B-cell NHL modifies the clinical and immunological course of Covid-19.

BCG Vaccination to Prevent COVID-19

NUEVA
Start date: December 7, 2020
Phase: Phase 3
Study type: Interventional

The current COVID-19 epidemic threatens to overwhelm the capacity of many countries to meet their populations' health care needs. Although several vaccines specific for SARS-CoV-2 have been or are being developed, these require testing in animal and human safety studies and they are unlikely to be available during the expected peak periods of the growing epidemic. Two groups at especially high risk of infection and disease are front line health care workers working directly with COVID-19 patients and elderly residents of group homes or facilities that provide skilled nursing care to this frail population. Interim measures to protect these groups while we await a high efficacy vaccine are desperately needed. Based on the capacity of BCG to (1) reduce the incidence of respiratory tract infections in children and adults; (2) exert antiviral effects in experimental models; and (3) reduce viremia in an experimental human model of viral infection, we hypothesize that BCG vaccination may induce (partial) protection against susceptibility to and/or severity of SARS-CoV-2 infection. This study will evaluate the efficacy of BCG to reduce risk of infection by SARS-CoV-2 and mitigate COVID-19 disease severity in at risk health care providers. A phase III randomized controlled trial provides the highest validity to answer this research question. Given the immediate threat of the SARS-CoV-2 epidemic the trial has been designed as a pragmatic study with a highly feasible primary endpoint, which can be continuously measured. This allows for the most rapid identification of a beneficial outcome that would allow other at-risk individuals, including the control population, to also benefit from the intervention if and as soon as it has demonstrated efficacy and safety.

NCT ID: NCT04615208 Withdrawn - Covid19 Clinical Trials

Screening for COVID-19

Start date: December 19, 2020
Phase:
Study type: Observational

Canada is entering the important yet dangerous phase of the COVID-19 pandemic: the reopening of industry. As such, there is an urgent need for a quick and accurate screening tool to help ensure people re-entering the workplace are COVID-19 negative. This proposal offers an innovative, simple-to-implement and quick screening tool for this purpose. This study hypothesize that breathing sounds of a COVID-19 positive person would have different characteristics even if the person is asymptomatic. This study aim the development of an integrated diagnostic pattern recognition tool in the form of a smartphone app, using audio and temperature as inputs to identify COVID-19 positive individuals. The proposed digital technology will screen individuals as healthy or possibly COVID-19 positive. The latter group will then be recommended for further testing. The goal of the proposed app is to provide much more accurate early screening (currently only temperature is taken), and to reduce the burden of COVID-19 tests. This digital technology will be used and tested in Manitoba initially and later nationally in Canada, with the potential of being publicly available in the future. To use the proposed screening tool, a smartphone is held within 1 cm of an individual's mouth and the individual instructed to take five deep breaths through the mouth. The individuals' breathing sounds will be recorded by the smartphone, while the participant's temperature will also be recorded by the heat camera. The app will first use its acoustic analysis to identify sounds as healthy or abnormal. If the outcome is abnormal, then a questionnaire will be provided, along with a further acoustic analysis to rule out other common comorbid conditions (e.g. chronic lung disease). Finally, based on the inputs, the diagnostic algorithm will decide if the individual should be referred for further testing or not. Since the proposed end product is a smartphone app, the two software partner companies will play a crucial role in the final integration and development.
