Filter by:The study purpose was to assess the outcomes of therapy with olokizumab within complex therapy of Coronavirus disease 2019 (COVID-19) in hospitalised patients in real clinical practice setting. The study investigated patients' characteristics, disease progression, and efficacy and safety of olokizumab therapy.
The present study is a 2-arm pragmatic randomised controlled trial (RCT) in which 310 patients who suffer from post-Covid syndrome are randomised to either a short-time outpatient-based rehabilitation program (the intervention) or care as usual in a 1:1 ratio. Assessments will take place immediately before randomisation (T0), after intervention or care as usual (T1), and 6 months after T1 (T2). Patients will be recruited from General Practitioners (GP's) as well as social media and self-referral to the involved institutions.
In December 2019, a novel pneumonia caused by a previously unknown pathogen emerged in Wuhan, China. The pathogen was soon identified as a novel coronavirus (SARS-CoV-2), which is closely related to severe acute respiratory syndrome CoV (SARS-CoV) COVID-19, caused by the SARS-CoV-2 virus, leading to a major global public health threat. Many COVID-19 patients develop acute respiratory distress syndrome (ARDS) leading to death. The recent RECOVERY Trial demonstrated the success of dexamethasone in treating late-stage COVID-19 patients. However, use of dexamethasone increases mortality in the early stage of the disease, and dexamethasone is further limited because the therapeutic dose and duration is insufficient to safely and effectively treat most COVID-19 patients. As the majority of cells have glucocorticoid receptors to which dexamethasone binds, highly toxic doses would be needed to effectively treat COVID-19, which results in increased mortality as well as decreased natural immunity (via T-cell and other immune cell modulation). The investigational product 101-PGC-005 ('005) - a prodrug of dexamethasone that is targeted to only activated macrophages - will address the many safety and efficacy issues that limit dexamethasone. '005 can achieve much higher anti-inflammatory doses and avoid all undesirable immunosuppressive activities caused by standard dexamethasone administration, resulting in an even greater reduction in mortality among hospitalized patients and significantly reducing long term morbidity in patients who survive.
The investigators hypothesize that early mobility condition and muscle power may be the predictive factors for Coronavirus disease 2019(COVID-19) patients' activity prognosis and hospitalization days. To prove our hypothesis, the investigators proposed a retrospective cohort study to see if ICU mobility scale(ICUMS) and Medical Research Council Sum Score(MRCSS) can predicted the patients' Barthel index after discharge and hospitalization days.
Thromboembolisms (TEs) in patients with critical COVID-19 has been reported to be three times higher than for other critically ill patients. Immunothrombosis has been proposed as a plausible mechanism for COVID-19 coagulopathy. Corticosteroids improve survival in patients with critical COVID-19, and likely even more so with a higher dose. However, the evidence regarding the impact on the incidence of thromboembolic and bleeding events are currently uncharted. The aim of this study is to investigate if there is a difference in the incidence of thromboembolic events during ICU stay in patients with critical COVID-19 when treated with 12 mg dexamethasone compared to 6 mg dexamethasone.
The study will be a prospective cohort design to determine if children generate aerosols that harbor a viral load similar to adults. Prior to beginning enrollment, researchers may recruit up to 10 participants (adults or children who meet inclusion criteria for the main study) to perform a small pilot to optimize our cold chain and laboratory procedures. The study will include children and adults who are confirmed SARS-CoV-2 positive and aim for a total sample size of at least 10 children and 10 adults. Hypothesis: As children have a high viral load in the nasopharynx, we hypothesize that children generate aerosols that contain SARS-CoV-2 virus. Aim: To estimate the viral load in aerosols generated from children with COVID-19 infection, and to compare the viral load contained in aerosols from children with aerosols from adults
The elderly, who are often in poorer health, have been particularly affected by the COVID-19 pandemic. Recent study results show that while vaccines have been very effective in the short term, protection for the elderly may not be sufficient 6 months after the 2nd dose. Some countries have started to offer a 3rd dose. We are considering acting on the intestinal flora of the elderly (which is often unbalanced) in order to increase the effectiveness of the vaccination. Indeed, it has been demonstrated that probiotics (which can rebalance the intestinal flora) significantly increase the production of antibodies after vaccination against the flu virus. Our hypothesis is that taking probiotics one month before and one month after the 4th dose of COVID vaccine would result in longer lasting vaccine protection in seniors. This study will include 668 seniors, aged 65-89 years, who have not had COVID-19, who have received 3 doses of an mRNA vaccine and who will accept a 4th dose of vaccine. All participants will take 1 capsule/day (probiotics or placebo) for 1 month and in the middle of this period will receive a 4th dose of vaccine. On five occasions (inclusion, vaccination,1 month, 3 months and 6 months post-vaccination), they will prick their fingertip and express the drop of blood on a blotting paper. They will mail this dried blood sample in an envelope for antibody testing in Quebec City. A subgroup of 100 participants willing to travel the Sherbrooke Clinical Research Center for 2 times (inclusion visit and final visit) will be invited to do a blood test. The investigators expect to reduce by 1/3 the number of seniors who are poorly protected by the 4rd dose of vaccine 6 months after the injection thanks to the probiotics. If successful, this approach could quickly be implemented worldwide as probiotics have few side effects and are affordable.
The objectives are to reduce dyspnoea, increase exertional capacity, increase vital capacity and respiratory muscle strength. vital capacity and respiratory muscle strength. In addition to increasing the sensibility of smell and taste, observing if there is a relationship between the decrease of these senses with the senses with appetite and whether appetite has normalised in post-SARS-CoV-2 patients. It is a randomised and blinded experimental study with a control group where the sample recruited will be 30 patients, with a range of of 30 patients, with an age range of 19-42 years, where they carried out an assessment of spirometry, modified Borg dyspnoea scales and modified Medical Research Council (MMRC), Singapure (MMRC), Singapore Smell and Taste Questionnaire (SSTQ) and weekly smell and taste questionnaire. taste questionnaire.
Novel antiviral drugs can mark a turning point in the prevention and treatment of patients with Covid-19. Recently, several independent large phase-III RCTs have shown that the intravenous administration of one gift of neutralizing SARS-CoV-2 monoclonal antibodies can reduce the relative risk of hospital admission and/or death with 70-85% in seronegative patients with SARS-CoV-2 infection when given within 3 to 7 days after state of symptoms. Moreover, novel oral anti-viral compunds such as molnupiravir and nirmatrelvir/ritonavir could reduce the risk of hospitalisation or death by 30% to89% in at-risk adults with Covid-19. These are potential breakthroughs in the treatment of SARS-CoV-2 infection and can be of special importantance for immunocompromised patients who have a diminished or complete lack of an effective humoral response towards Covid-19 vaccination. Monoclonal SARS-CoV-2 antibodies and antivirals have been given an emergency use authorization by regulatory authorities and are or will become available in the Netherlands to treat SARS-CoV-2 infected patients who are at high risk of developing severe disease. Now, urgent key questions need to be addressed: Which patient categories will benefit most from these new drugs? What are the SARS-CoV-2 viral load as well as inflammatory response kinetics during and after treatment with the new SARS-CoV-2 therapies? What is the safety profile in () patients; do new SARS-CoV-2 variants occur during treatment? This study aims to establish a prospective cohort together with a biobank of patients treated with new SARS-CoV-2 therapies to evaluate its real world effect and safety. Primary Objectives: - A. What are the SARS-CoV-2 viral load kinetics during and after treatment withneutralizing monoclonal antibodies and other antiviral agents against SARS-CoV-2? - B. Do viralvariants, spike mutations and immune escape occur during treatment with neutralizing monoclonal antibodies and other antiviral agents against SARS-CoV-2?new SARS-CoV-2 therapies? - C. What are the viral antibody and inflammatory response kinetics during and after treatment with neutralizing monoclonal antibodies and other antiviral agents against SARS-CoV-2? - D. To create a biobank to address future questions regarding the current use of neutralizing monoclonal antibodies and other antiviral agents against SARS-CoV-2compared to novel COVID-19 treatments which are in development. Study design: Establishment of an observational cohort study including a biobank of patients who receive neutralizing monoclonal antibodies and other novel antiviral agents against SARS-CoV-2. Study population: All patients above 18 years of age treated with neutralizing monoclonal antibodies and other novel antiviral agents against SARS-CoV-2. Intervention (if applicable): None Main study parameters/endpoints: Viral load kinetics during treatment. Viral mutations during and after treatment. Presence of monoclonal antibody during treatment and host antibody production and inflammatory responses during treatment. Nature and extent of the burden and risks associated with participation, benefit and group relatedness: Participating in this observational study will not directly benefit the participants and healthy volunteers. The study will provide information about the effect, host response and safety of thse new anti-SARS-CoV-2 therapies during Covid-19. Clinical data will be obtained through the electronic patient dossier. The knowledge obtained can potentially benefit Covid-19 patients in the future by optimizing treatment strategies. The burden and risks for patients participating in the TURN-COVID biobank study is minimal. Patients will be visited by a research physician or research nurse during or within three days after receiving neutralizing monoclonal antibodies and other antiviral agents against SARS-CoV-2. Baseline data regarding medical history, admission and vital parameters will be collected through the electronic patient dossier. At the follow-up visits we will draw a total of (3x 43 ML and 1x16 ml = 145 ml of venous blood) and obtain 4 oro-/nasopharyngeal swabs divided over four time-points (day of treatment and day 7, 28 and 90 post treatment).
Coronavirus (COVID-19) vaccines have saved millions of lives since release and remain a key tool in the fight against the pandemic. However, most countries have not reached the vaccine uptake rates needed to relieve pressure on hospitals and intensive care units (ICUs) during peak corona periods. Reduced effectiveness of vaccines in preventing infections with the Omicron variant and milder courses of the disease may trigger and support beliefs that vaccination is no longer necessary, especially among vaccine sceptics.The term 'vaccine sceptic', however, is used heterogeneously and often interchangeably to describe both 'vaccine hesitants' and 'vaccine deniers'. In contrast to vaccine deniers, characterized by a definite and unwavering decision not to get vaccinated, vaccine hesitants are characterized by a spectrum of indecisiveness, with a high need for information on both benefits and harms. They may still decide to get vaccinated if information succeeds in convincing them. In light of the potential for a change of mind in vaccine-hesitants the key question is: How does one best address their high needs for balanced risk ratio information? Evidence from cognitive and behavioral science suggests that interactive simulations of risk information, which imitate mechanisms by which humans sequentially and experientially sample risk information naturally, can be more effective in helping people develop adequate risk perceptions and initiate behavioral change than the ubiquitously used conventional text-based formats. The study therefore seeks to determine if interactive risk ratio simulation relative to a text-based format are more effective in prompting positive change in unvaccinated, vaccine-hesitant respondents' intention to get the COVID-19 and also in the respective benefit-to-harm ratio assessment during the Omicron wave in Germany.
