Filter by:Covid-19 is associated with the onset of anti-SARS-CoV-2 antibodies; in a majority of patients, neutralizing antibodies are detected. However, the long-term persistence of such protective antibodies is not known. The investigators will explore patients with a proven Covid-19 (positive PCR) 6 and 12 months after the diagnosis to determine whether neutralizing antibodies are still detected. The investigators will determine whether this persistance varies according to - the severity of the Covid-19 - a treatment by steroids during the covid-19. This will help to anticipate whether a second wave of infection is possible in a non-naive population.
Methods: Single-center pilot study included PCR+ SARS-CoV2-patients, hospitalized from April to May 2020 in Puebla, Mexico. Comparative treatment with steroids plus CsA or steroids. Mild, moderate or severe pneumonia was measured by clinical, laboratory tests, lung damage score by computed tomography, and score for clinical improvement. Death rate was evaluated at 28 days.
Investigators study meet the World Health Organization definition of a clinical trial because it is a prospective study in which participants will be assigned to intervention groups to investigate the effects on health outcomes. Investigators highlighted clearly the real problem that indigeneous patients are facing now in the Democratic Republic of the Congo: Poverty meaning the lack of money to buy goods and drugs. From the news report, investigators learned that "In the Democratic Republic of the Congo, indigenous communities in Kananga, Tshikapa and in the Kasai region are increasing their consumption of "Vernonia amygdalina," a traditional plant believed to cure several diseases, including alleviating COVID-19." Based on an unpublished work, quite a few extract molecules of Vernonia amygdalina are excellent antiviral candidates which are the family members of Remdesivir in terms of their antiviral mechanisms. Furthermore, the antiviral capabilities of these molecules are significantly stronger than or at least equivalent to Remdesivir. The target zones of these molecules in the human body cover a set of important organs and tissues. For example, Vernolide (C19H22O7) is able to reside firmly at bronchi, the upper respiratory tract, and blood vessels. From the news report, investigators learned also that Herbs used in Tanzania include lemon, ginger, neem tree leaves, mango tree leaves, orange tree leaves. These traditional medicines contain, more or less, antiviral molecules whose capacities range from good to outstanding levels. Those herbs have been used worldwide to fight COVID-19. In conclusion traditional medicines have been playing important roles not only in Africa but also in Asia, in South America, etc. Herbs prove themselves with effective efficacies in many therapeutic practices. So maybe after careful considerations, the World Health Organization may support the use of herbs for poor patients who cannot afford modern drugs and used traditional medicines after a positive COVID-19 test in the Democratic Republic of the Congo. Investigators are talking about a randomisation's nuance process to follow participants who decide by themselves if diagnosed positive to COVID-19 to begin to take herbs not waiting for a physician prescription.
The negative global consequences of the COVID-19 pandemic has prompted efforts to develop efficient laboratory testing protocols that can be quickly scaled in a practical way. Traditional phlebotomy requirements for antibody testing (venipuncture) often serve as a barrier to widespread population testing since they typically require dedicated facilities and personnel training. Conversely, antibodies are typically very stable in blood and require very little testing volume, which make antibody tests well suited to be run on samples collected via finger-stick, saliva, or other self-administered collection devices. Salveo Diagnostics is a CLIA/CAP certified clinical laboratory that routinely performs testing for anti-SARS-Cov-2 antibodies. The purposes of this protocol are to 1) assess the feasibility of streamlined sample collection procedures for assessing COVID-related immune status, and 2) to provide a mechanism for securing sequential samples in COVID positive and negative patients to support additional studies (e.g. investigating timing of anti-SARS-CoV-2 antibody class switching and antibody persistence).
Describe the immune response of patients affected by SARS-CoV-2, including an assessment of the types of antibodies elicited by the infection, specifc antibody titers for the different isotypes, evolution of the antibody response over time, protective efficacy and immune correlates of protection. investigate genetic determinants of Covid-19 and of the imune response to this condition. Finally, the study will investigate secondary infection rate and its determinants among household contacts of Covid-19 patients.
Methodology: This is a controlled, randomized, multicenter open-label Phase Ib clinical exploratory trial in patients with fibrosing interstitial lung disease secondary to SARS-CoV-2 infection. Patients who give informed consent will be screened for enrolment in the study. Patients that meet the eligibility criteria will be enrolled and randomly allocated in the control arm (best standard of care) or the experimental arm (best standard of care plus IN01 vaccination). The patients enrolled in the control arm of the study will receive standard of care. The primary endpoint is safety, measured by the Frequency and severity of AEs graded according to Common Terminology Criteria for Adverse Events (CTCAE) Version 5.0 criteria. Biochemical and blood count alterations will be also monitored. Safety will be defined based on the frequency and severity of adverse events (AEs) throughout the patient's participation in the study comparing between control and experimental arms. Efficacy will be measured as function of the annual rate of decline in the Forced Vital Capacity (FVC) at 1 year after patient inclusion in the study and the blood oxygen saturation levels at days 1, 14 (w2), d 28 (w4), 42 (w6) and 92 (w12); week 24, week 36 and week 52. High-resolution Computed Tomography (CT) scans will be taken at at baseline and weeks, 12, 24, and 52 to evaluate the resolution of the fibrosing interstitial lung disease. A translational substudy will be included. Objectives: Primary Objective ● To evaluate the safety and tolerability of IN01 vaccine in diagnosed ex-COVID-19 patients that develop fibrotic lung syndrome after infection. Secondary Objectives - To evaluate the effect of IN01 vaccine on Oxygen saturation, pulmonary function, quality of life and fibrosing status in ex-COVID-19 patients that developed fibrosing lung disease after infection. - To assess biomarkers and molecular markers related to the IN01 vaccine mechanism of action.
This is an open-label, randomized, multi-centre study where hospitalized subjects will be randomized in a 2:1 ratio to receive Isoquercetin (IQC-950AN) in addition to standard of care or standard of care only for 28 days following confirmation of a COVID-19 infection.
Brazil has the Latin America's largest coronavirus outbreak, numbers second only to the United States in the western hemisphere. The first COVID-19 confirmed case in Brazil was on February of 2020. A 61yrs old man tested positive after returning from a trip to Italy. Few other very first cases were also imported from Europe by returning travelers. The first locally transmitted case was registered on March of 2020, when a total of 8 cases have already been confirmed. At the time the WHO declares the outbreak as a pandemic (March 11) Brazil had 52 confirmed cases being 6 of those locally transmitted. Healthcare professionals are now more important than ever. Given the intrinsic nature of the hands-on treatment of the Chiropractic profession, it is extremely important to understand what strategies chiropractors have put in place to address patient care, safety, and self report COVID contamination of those professionals.
Background: Based on data from the 2003 SARS-COVID pandemic, other serious lung infections, and patients with respiratory distress, it is estimated that 10-30% of patients with severe SARS-COVID-2 pneumonia may present as a sequel an organized pneumonia. The treatment of this complication is not well defined. The use of oral corticosteroids is mandatory to avoid a possible evolution to pulmonary fibrosis, however, the doses to be administered and the duration of treatment are unknown as there is no study specifically aimed at solving this doubt. Many authors advocate high-dose treatment regimens for a minimum of six months, as proposed for cryptogenic organized pneumonia. However, there is a question whether in non-idiopathic cases of organized pneumonia, less intense treatment could resolve the disease. Hypothesis: The use of a less intensive prednisone regimen may be sufficient for therapeutic control in patients with post-COVID-19 organizing pneumonia, in relation to the established standard regimen Simplicity of the procedures: The objective of the NORCOVID study is to identify the optimal treatment regimen with corticosteroids in post-COVID19 patients diagnosed with NO. Specifically, the primary objective of this multicenter randomized trial is to evaluate whether treatment with a less intensive regimen of corticosteroids produces a non-inferior therapeutic effect than the established control regimen. Secondary objectives are to evaluate the effect of treatment on secondary efficacy variables and on safety. DLCO, respiratory function tests, 6MWT test, need for rescue, radiological tests, complications, mortality and the WHO ordinal scale will be evaluated.
It will be performed a randomized, multicenter, triple-masked, placebo-controlled clinical experiment to determine the effectiveness and safety of the administration to of ivermectin at a dose of 200 mcg/kg once a week for 7 weeks in a prophylactic treatment against SARS COV-2 infection in 550 Colombian health workers during the COVID-19 pandemic.
