Filter by:The primary objective of this study is to evaluate the safety and tolerability of intravenous (IV) IMM-BCP-01 in subjects with mild to moderate COVID-19 through Day 28. The secondary objectives of the study are to: - Determine pharmacokinetics (PK) and evaluate viral clearance after single ascending doses of IV IMM-BCP-01 in subjects with mild to moderate COVID-19 through Day 28. - Evaluate the safety and tolerability, determine PK, and evaluate viral clearance of single ascending doses of IV IMM-BCP-01 in subjects with mild to moderate COVID-19 through Week 12.
The Coronavirus Disease 2019 (COVID-19) pandemic has resulted in catastrophic infections and fatalities across the nation. Many older Veterans with comorbidities are especially vulnerable to complications and poor recovery. This award will investigate the effect of a novel, home-based, supervised, group exercise tele-rehabilitation in Veterans recovered from COVID-19 on cardiopulmonary and physical function.
Patients with COVID-19 may experience prolonged physical and psychological symptoms after weeks or months of the infection. This may be caused by a combination of factors including poor nutrition, low physical activity, and lack of emotional support. Leading to poor overall health and low quality of life. This evidence indicated that people with long COVID-19 need a personalized intervention. Our objective is to determine if the use of an online application that is based on preventive self-care and that includes nutrition and mindfulness will be feasible to use for patients with long COVID.
The term post-acute COVID-19 syndrome or Long COVID is a disabling syndrome that persists beyond the 3-month convalescence period after COVID-19 infections. This syndrome affects mostly women (~80%), present with chronic tachycardia and Orthostatic intolerance symptoms without any identifiable cause. In addition, non-specific symptoms such as fatigue, headache, and "brain fog", commonly described in POTS patients are also present in this novel condition, recently named post-COVID-19 tachycardia syndrome, POTS variant. Reduced Vagal activity and unresolved inflammation is post-COVID-19 POTS is hypothesized as the cause of Long COVID
It is important people receiving immunosuppressive therapy are provided with the best protection against COVID-19 because they are at greater risk of severe illness should they become infected. As severe immunosuppression can reduce the efficacy of COVID-19 vaccination, doctors agree that COVID-19 boosters is are important to maximise the vaccine response in these people. However, we don't currently know the best time to give booster vaccines to people about to start immunosuppressive therapy. This research aims to address this knowledge gap by examining whether the greatest protection is provided by giving the COVID-19 booster just before the immunosuppressive therapy starts or by waiting and giving the booster 6 months after treatment start. At the 6-month timepoint, in many cases the more intensive immunosuppression is often weaning and the immune system is starting to rebuild.
This is a tertiary care hospital-based prospective molecular epidemiology study in Montreal, Canada. When nosocomial transmission was suspected by local infection control teams' investigations, SARS-CoV-2 viral genomic sequencing was performed locally for all putative outbreak cases and contemporary controls. Molecular and conventional epidemiology data were confronted in real time to improve understanding of COVID-19 transmission and reinforce or adapt prevention measures.
An effective vaccine stands as the most effective way for controlling the COVID 19 pandemic , yet, immunogenic vaccine efficacy needs to be extensively studied . T cell responses against the structural proteins have been found to be the most immunogenic in peripheral blood mononuclear cells of convalescent SARS-CoV1 patients which needs to be tested in SARS -COV2 vaccine efficacy studies alongside with the sustainability of humoral and cellular immune responses . Clinically , immunocompromised patients face drastic outcome of infections , which led the Advisory Committee on Immunization Practices (ACIP) - USA -and the Joint Committee on Vaccination and Immunisation (JCVI) -UK- recommend COVID-19 vaccination of immunocompromised , the WHO Strategic Advisory Group of Experts on Immunization (SAGE), recommended that the three vaccines(Pfizer ,Moderna and Astra Zeneca) can be used for individuals with high-risk comorbidities . Nevertheless, there is an unmet research need concerning the immune response towards COVID 19 vaccination in this population . Based on the previous work of our team in designing B and T cell epitopes distributed over the S protein , we will study the immune response in the available vaccines in Egypt.
Rationale: In patients with COVID-19 admitted to the hospital, large heterogeneity exists in patients, timing and dosing of steroid therapy. It is unclear how to treat patients who fail dexamethasone therapy. High-dose steroids are prescribed mainly in patients with the most severe disease, which may be too late given the potential escalation of pathophysiological pathways in these patients. Objectives: The main objective is to determine the most optimal form, timing and dosing of steroid therapy to reduce the morbidity and mortality of patients admitted to the hospital for COVID-19. This objective will be addressed in 4 work packages (WP): - WP-1A-ward admission: What is the effect of higher dose steroids upon hospital admission on clinical deterioration and what would be the optimal timing of increasing steroid dosage? - WP1B-ward late: Do high-dose steroids, compared to no steroids, improve outcomes in dexamethasone-unresponsive COVID-19 patients on the ward after dexamethasone 6 mg/day for 10 days? - WP2-ICU admission: Do high-dose steroids, compared to 6 mg/day dexamethasone or its equivalent, improve outcomes in patients admitted to the ICU with moderate/severe C-ARDS? - WP3-ICU late: Do high-dose steroids, compared to no steroids, improve outcomes in ICU patients with moderate/severe C-ARDS after dexamethasone 6 mg/day for 10 days? - WP4-biobank: Can biomarkers help predict outcomes after (high dosed) steroid therapy? Study design: Retrospective observational multicenter study in the Netherlands. Study population: Adult patients (≥ 18 years) hospitalized with COVID-19 will be included, more specifically: Intervention (if applicable): Not applicable (retrospective study design). Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Given the retrospective nature of the study, no burden, risks or benefits for the patient are associated with participation. The target population of this study is specific to hospitalized patients with COVID-19.
Loss of the sense of smell is a characteristic feature of COVID-19 and likely related to viral invasion of the olfactory mucosa but is also a prodromal feature of PD. This constellation has kindled concerns that COVID-19 - similar to the Spanish Flu Pandemic in 1918 - might trigger a second wave of post-infectious parkinsonism. The main objective of the study is to probe for the presence of pathological α-synuclein assemblies in the olfactory mucosa of patients with COVID-19.
Various observational studies have reported an association between influenza vaccination and lower rates of infection with SARS-Cov-2 and less COVID-19 disease severity have been reported in large epidemiological studies in US, Brazil and Italy. Observational studies from the Netherlands showed also strongly reduced COVID-19 infection rates among influenza-vaccinated healthcare workers, with ORs of 0.61 and 0.49 for the first and second wave of COVID-19, respectively. In addition, in-vitro immunological analyses showed that the quadrivalent inactivated influenza vaccine can induce a trained immunity program against SARS-CoV-2 (2). In-vivo vaccination against influenza was also shown to induce improved interferon responses against SARS-CoV-2, with modulation of hyperinflammatory responses. Trained immunity could be the underlying mechanism for the potential protective effect of influenza vaccine, a mechanism that has also been proven for BCG vaccination, and epidemiological evidence suggests similar non-specific effects of MMR and OPV vaccination. Currently, various clinical trials are being conducted to study the impact of BCG, MMR and OPV vaccination on COVID-19, but prospective clinical data on influenza vaccination are lacking. Although specific COVID-19 vaccines have been developed and are proven effective, there are important reasons for assessing in a controlled randomized trial the effect of influenza and MMR vaccine on COVID19: - Specific COVID-19 vaccines are still not yet available for all segments of the population, and especially not for the majority of the population in developing countries. - The emergence of new SARS-CoV-2 variants, especially the P1 variant from Brazil, may very well be associated with reduced response to vaccines. An immunomodulatory protective vaccine that protects in an antigen-independent manner would be of great importance. - It would also be conceptually important to know whether influenza and the MMR vaccine can induce heterologous protection against another viral infection, in the context of future pandemics.
