Filter by:Current management of COVID-19 (coronavirus) is mainly supportive, and respiratory failure from acute respiratory distress syndrome (ARDS) is the leading cause of mortality. Cytokines and chemokines are thought to play an important role in immunity and immunopathology during virus infections. Patients with severe COVID-19 have higher serum levels of pro-inflammatory cytokines (TNF-α, IL-1 and IL-6) and chemokines (IL-8) compared to individuals with mild disease or healthy controls, similar to patients with severe acute respiratory syndrome (SARS). Cannabidiol (CBD), a nonpsychotropic ingredient of Cannabis sativa, possesses potent anti-inflammatory and immunosuppressive properties. These effects are mediated by T cell attrition and by inhibition of pro-inflammatory cytokine release (tumor necrosis factor-a, Interferon gamma, IL-1b, IL-6, and IL-17) and stimulation of anti-inflammatory cytokine production (IL-4, IL-5, IL-10, and IL-13). In a number of phase 2 trials involving more than 100 patients, our group was able to show the safety and efficacy of CBD in the prevention and treatment of graft-versus-host disease. Based on these data, we will test the cytokine profile, safety and efficacy of CBD treatment in patients with severe and critical COVID-19 infection.
Invasive mold infections (IMI) mainly affect patients with hematologic malignancies receiving intensive chemotherapy or after hematopoietic stem cell transplantation (HSCT). Prolonged neutropenia after remission induction chemotherapy (>10 days duration) and continuous immunosuppression in the context of prevention or therapy of graft versus host disease (GVHD) for HSCT recipients (first 100 days post-transplantation and thereafter if GVHD is present) are considered as periods at high risk of IMI. Posaconazole prophylaxis is prescribed according to current guidelines to reduce the occurrence of IMI. Nevertheless, breakthrough IMI (bIMI), i.e. IMI occurring under mold-active prophylaxis, are still observed. The investigators hypothesized that the epidemiology of bIMI (under posaconazole prophylaxis) differs from that of IMI occurring in the absence of mold-active antifungal prophylaxis. Because bIMI are rare events since the introduction of posaconazole prophylaxis, epidemiological data of bIMI are scarce. This study aims to i) describe the epidemiology, clinical features, treatment and outcome of bIMI, ii) assess the causes of bIMI, iii) determine potential risk factors associated with the developllement of bIMI iv) assess the impact of bIMI on overall mortality. Design Retrospective and prospective, observational, case-control, multicenter, international study. The retrospective part will enroll previously identified bIMI cases and control cases (1:2) over the last five years: October 1st 2015 to September 30st 2020. The prospective part will enroll bIMI cases and control cases (1:2) occurring over a two-year period: October 1st 2020 to September 30st 2022. Setting The aim is to enroll 10 to 15 European centers with dedicated units for hematologic cancer patients. Currently, six centers have confirmed their participation (from Switzerland and Germany). Study Population Adult (≥ 18 years old) patients with a hematologic malignancy receiving posaconazole prophylaxis during induction, consolidation or re-induction chemotherapy or after HSCT. Cases : patients receiving posaconazole prophylaxis for at least 7 days and diagnosed with bIMI proven or probable according to EORTC-MSGERC. Controls: patients receiving posaconazole prophylaxis for at least 7 days, without diagnosis of bIMI possible, probable or proven according to EORTC-MSGERC. The objective is to enroll about 100 bIMI cases and 200 controls.
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.
At present, the offer of tests for the serological diagnosis of CoVID-19 (detection of IgG, IgM or IgA antibodies against CoV-2 SARS) is plethoric and is based on the use of a very large number of rapid diagnostic unit tests, a few dedicated high throughput automated systems or reagents on existing open systems. The offer will continue to expand in the coming months. In order to meet the objectives mentioned by the Prime Minister, and confirmed in the HAS report of April 16, 2020 and in the opinion n°6 of the COVID-19 scientific council concerning the potential use of these serological tests at the end of the COVID-19 epidemic, the Virology laboratory wishes to validate the sensitivity and specificity of the tests it intends to use.
The SARS-CoV-2 (COVID-19) infection is causing a global pandemic and a major health crisis in France. Immunity is the body's ability to defend itself against infectious agents such as viruses. The progressive acquisition by a large part of the population of immunity to defend itself against the COVID-19 virus is one of the main mechanisms by which a resolution of this pandemic is hoped for. Recovery from infection and protection from the virus is likely to depend on the development of antibodies (proteins produced by the body to neutralize infectious agents) and T-cells (a type of white blood cell in the immune system) that can stop the virus from multiplying and killing it. To date, the way and speed at which the T-lymphocytes active against the virus appear are not known. The development of biological tests to detect T-cells active against the virus in the blood of infected patients is therefore necessary. In this context, we propose you to participate in a study that will study the immune system's response against the sars-CoV-2 virus during and after COVID-19 infection.
The aim of this study is to evaluate whether there are indicators of central sensitisation in patients post covid-19 infection.

COVID-19, the coronavirus responsible for the pandemic that began at the end of 2019 in China, spreads through respiratory droplets and direct contact. The most common symptoms of the disease include fever, cough, asthenia or myalgia, wheezing and headache, and the most serious complication is acute respiratory distress syndrome (ARDS). The new coronavirus has continued to spread to multiple countries and continents so much so that the epidemic was declared a Public Health Emergency of International Interest (PHEIC) by the World Health Organization (WHO) on January 30, 2020. In the first phase of emergency worldwide, characterized by high morbidity and mortality, scientific interest has been mainly directed to the study of the transmission mechanisms of the infection, diagnostic tools and therapies for ARDS, especially in elderly and co-morbid patients. Interest has rapidly spread to other categories of patients and in particular to pregnancy, on which the virus could impact in different ways, with consequences for both the mother and the fetus. A recent systematic review that included all published reports on Coronaviruses (COVID-19, SARS, and MERS) in pregnancy showed that preterm delivery is the most frequently reported adverse event in these women, and that COVID-19 is associated with an increased risk of preeclampsia and caesarean section. Nonetheless, the limited sample size, the main inclusion of cases reported for acute respiratory symptoms, the lack of information on previous pathologies potentially capable of complicating pregnancy, do not allow for the extrapolation of strong evidence on the course of infection in pregnancy. Therefore, the current status of the scientific literature does not allow for general and wide-ranging implications. THe investigators therefore believe it is particularly useful to investigate maternal and fetal outcomes in this new broader scenario, including all pregnancies associated with asymptomatic or symptomatic SARS-CoV-2 infection, found in any gestational period, in order to evaluate in a "real world scenario" "Actual rates of maternal-fetal and neonatal adverse events
COVID-19 has affected almost all countries in the world. Every other country is constantly working towards its treatment and development of vaccines, with little to no success so far. Recently, several regimens have been tried as antiviral medicine. Among these medicines, Favipiravir is considered a broad-spectrum antiviral with the spectrum of activity noted against a wide range of RNA viruses & a good oral antiviral drug with > 97% bioavailability. It has already proved its safety profile as it has received FDA indication for drug-resistant Influenza. There has been increasing evidence of favorable outcome against COVID-19 in terms of early viral clearance & quicker symptomatic relief however, most of these studies lack strong statistical significance & are not peer-reviewed. Subjects will be categorized into two arms based on the severity of infection due to COVID-19 defined by NMC guidelines. Each arm will have respective two groups as the study drug group and control group. Based on the sample size calculation, subjects will be stratified & randomly enrolled in the study after checking the eligibility criteria at the screening visit. About 276 mild patients will be recruited for this trial and 400 moderate patients (including 10% loss ). Study arm groups will receive a Favipiravir treatment of 1800 mg PO BID on day 1, then 800 mg PO BID from day 2 onwards and control groups will receive the same quantity of Placebo. Treatment will be continued till 5 days after for mild groups and 10 days for moderate groups. Eligible patients will be randomly assigned (1:1) to either Favipiravir or Placebo among mild cases; and Favipiravir or Remdesivir among moderate cases. Randomization will be stratified by age group (18 to 40 years, 40 to 60 years and 60 to 80 years) and co-morbidity. The permuted block (30 patients per block) randomization sequence, including stratification, will be prepared by a statistician using STATA-15 software. Eligible patients will be allocated to the respective arm and will receive individually numbered packs, according to the sequence order as informed by the hotline. Informed written consent will be taken from the participants before commencing the study. All safety data, patient's baseline, clinical outcome data, data from endpoints and variables should be reported by the clinician and his/her team in a pre-instructed case report form (CRF) via a designated website. It is our assumption that if the study results come favorable, Favipiravir, when used in mild or moderate cases, might prevent progression of the disease to higher severity, helps achieve viral clearance early so as to positively impact disease transmission in the community, increase the quality of life by quicker symptom recovery & decrease health burden by shortening the length of stay at the hospital. These findings can also be useful in international scenarios where the world is looking for innovative measures to curb COVID-19 infection. The study findings will be disseminated within and outside the country and will be published in peer-reviewed journals.
