Active clinical trials for "COVID-19"

This randomised trial aims to assess the role of beta1-3 glucan supplementation in improving clinical symptoms and other outcomes amongst hospitalised patients with COVID-19.

Retrospective analysis of real-world disease outcomes in non-severe COVID-19 patients with high risk factors of progression to severe disease, including death, without definitive anti-SARS-CoV-2 treatment

The study staff will conduct a hybrid type 1 effectiveness implementation 2-arm trail with 360 Black young adults from Alabama, Georgia, and North Carolina. Participants will be randomized to receive the standard of care (control) or the TT-C intervention arm, each with a balance of 180 participants. Primary effectiveness outcome is COVID-19 vaccine uptake define as receipt of any vaccine (primary series or secondary booster). Secondary effectiveness outcomes are vaccine hesitancy, confidence, and knowledge, attitudes, and beliefs. The study staff will also conduct qualitative interviews with a group of purposively selected AA-YA participants (est. n=12-16) and site staff (est. n=6-8) to assess barriers and facilitators to implementation. The hypothesis is that the intervention arm will be more effective than the control arm at increasing vaccine uptake.

In the current COVID-19 pandemic, many patients have an acute respiratory distress syndrome (ARDS). Among mechanisms related to COVID-19 acute respiratory distress syndrome, cytokine storm and secretion of IL-6 play a central role. ARDS management involves intubation for protective mechanical ventilation, deep sedation and curarisation. During intensive care unit (ICU) hospitalization, improvement of hematosis induces a switch from a controlled ventilation mode to a withdrawal ventilation mode, such as Spontaneous Ventilation with Pressure Support (SP-PS) or Adaptative Support Ventilation (ASV). This step is essential prior to considering complete weaning from controlled ventilation and sometimes ends with a failure. In this case, deterioration of hematosis and/or ventilatory mechanics is observed. At the same time as withdrawal failure, the investigators observed biological inflammatory rebound in some patients. Therefore, influence of inflammatory biological parameters, including IL-6, on withdrawal failure, needs to be investigated. To this end, the investigators decide to dose different inflammatory markers - such as IL6, C-Reactive Protein (CRP), Procalcitonin (PCT) - in patients with acute respiratory distress syndrome due to COVID-19, during standard of care. Indeed, in patients with acute respiratory distress syndrome not due to COVID-19, the increase in IL6 is a negative prognosis during medical first aid but also when the mechanical ventilation is withdrawn. In addition, IL6 rise is associated with poor prognosis for patients with COVID-19 and longer stays in intensive care.

The aim of the study is to assess the incidence of potentially inappropriate medication (PIM) administration, polypharmacy, and potential drug-drug-interactions (PDDIs) in cardiovascular patients enrolled in the reimbursement program in the time of coronavirus disease (COVID-19) pandemic. Medical information system (MIS) "BARS" will be used for inclusion and retrieval of relevant data of cardiovascular patients aged 75 years and older enrolled in the reimbursement programs in the Tomsk Region. The incidence rates of PIM prescriptions will be assessed. Potentially inappropriate medications will be defined according to 2015 Beers criteria. Polypharmacy will be defined as being administered five or more medications at the same time. PDDIs will be checked with Medscape Drug Interaction Checker and rated as 'Contraindicated', 'Serious', and 'Requiring Monitoring'. Combined analysis of retrospective and prospective occurrences of study parameters will be performed. PIM-BARS will evaluate the incidence rates and patterns of PIM prescriptions, polypharmacy, and PDDIs in elderly cardiovascular patients enrolled in the reimbursement program in the time of COVID-19 pandemic.

The effectiveness of COVID-19 vaccines in reducing the risk of severe COVID-19 is currently demonstrated. In France, since the beginning of the vaccination campaign, 54,266,859 people have received at least one injection (ie. 80.5% of the total population), 53,354,698 people now have a complete vaccination schedule (ie. 79.1% of the total population) and since the beginning of the booster campaign, 39,558,416 people have received a 1st booster dose. However, the data currently available on the persistence of immunity on the one hand, and the appearance of viral variants with reduced sensitivity to vaccine immunity on the other, suggest the need to administer booster doses at variable intervals depending on age and comorbidities. Real-life efficacy data from France and around the World confirm that people who have received a booster dose are better protected than those who have only received a primary vaccination schedule (HAS). In this context, the Ministry of Health, has pronounced on the possibility of administering a second booster dose for people aged 60 and over. Moreover, the recommendations for the Haute Autorité de Santé for the 2nd booster dose in general population should be available in June 2022. Three vaccines, mRNA BNT162b2 vaccine, Sanofi/GSK monovalent D614 and B.1.351 formulations were administered as 1st booster in the CoviBOOST trial. All three vaccines boosted antibodies and neutralizing response after a BNT162b2 initial course. Heterologous boosting with the Sanofi/GSK SARS-CoV-2 recombinant adjuvanted protein vaccine B.1.351 (Beta formulation) provided higher rates of neutralizing antibodies against variants, including Omicron BA.1, compared with the mRNA BNT162b2 vaccine. Due to the start of the study after the beginning of booster vaccination campaign in elderly, the enrollment of participants over 65 years of age was difficult so, only 8 subjects aged 60 years and over were enrolled. As vaccine immunogenicity is lower in older populations and is waning more rapidly, it is important to evaluate the adjuvanted vaccine in this population. The objective of this ancillary study is to compare, in participants aged of 60 years and older and previously vaccinated with 3 doses of mRNA vaccine (2 doses of Pfizer BioNTech) and a 3rd dose of Pfizer BioNTech or Moderna, the immunogenicity of a second booster dose of the B.1.351 strain recombinant protein- based subunit vaccine to BNT162b2 (mRNA Pfizer BioNTech Vaccine).These results will provide important information for booster vaccination recommendations in this age group.

This is a multicenter designed Phase III clinical trial. About 10000 participants plan to be enrolled.The objectives of this study are to evaluate the efficacy, safety and immunogenicity of the recombinant two-component COVID-19 vaccine (CHO cell) in adults

Vitamin D plays a pivotal but still not well understood role in the immune response to coronavirus disease (COVID-19) infection and vaccination. Many studies also showed a high negative correlation between the severity of inflammatory disease and serum 25-hydroxyvitamin D levels. Patients with acne vulgaris often had deteriorated skin condition after COVID-19 vaccination. Therefore, this study aimed to investigate the relationship of COVID-19 vaccination with serum 25-hydroxyvitamin D level and severity of acne vulgaris.

Olfactory dysfunction (OD) like hyposmia or anosmia has been realized as a common symptom or even cardinal sign of the disease and can be persisting after recovering. There are two different hypotheses on the pathogenesis of OD in past COVID-19: The central hypothesis, which speculates on neurotrophic abilities on olfactory receptors in the neuroepithelium, and the peripheral hypothesis, which speculates on damage of the sensory olfactory epithelium. Potential treatment strategies aim for the unique neural plasticity of the olfactory system and its potential for recovery. Clinical studies and case reports have shown a promising effect of olfactory training (OT) by frequent sniffing and/or exposure to odors 2-4 times a day for several weeks. The main objective of the study is to assess the effects of olfactory training in patients with COVID-19 related OD on: objective olfactory testing with the Sniffin' sticks test (identification and discrimination) (primary endpoint), subjective OD and its impact on the daily life (key secondary endpoint), other clinical scales and questionnaires referring to OD-related mood and quality of life (other secondary endpoint), gender differences in COVID-19 related OD (exploratory endpoint). Approach / methods OT will be performed twice a day with a 4-odor training set for 12 weeks. Effects of OT on COVID-19 related OD will be measured with objective and subjective efficacy variables. The sense of smell is an important function for social relationships and is therefore a challenging clinical problem with few proven therapeutic options. With this new approach, we want to investigate a possible simple treatment for an impedimental symptom of COVID-19, but also learn more about the pathomechanism of post-infectious OD. To our knowledge, this will be the first study comparing patients with COVID-19 associated OD with and without OT in clinical outcomes.

The health care is faced by a growing challenge in the years to come: increasing age and chronic morbidity raising the costs, combined with decreased work participation. Among the conditions on the rise, we find anxiety/depression, musculoskeletal conditions, type 2 diabetes and chronic obstructive pulmonary disease. Recently, the rise of the Corona pandemic has yielded another group of (primarily young) patients with decreased work capacity, the post-Covid syndrome sufferers. The aim of the present study is to establish, describe and summarize the experiences with a novel approach to rehabilitation for five of the most costly conditions; 1) low back pain, 2) chronic obstructive pulmonary disease, 3) type 2 diabetes mellitus, 4) mixed anxiety/depression and 5) post-Covid fatigue. The concentrated interdisciplinary rehabilitation is characterised by three phases; Pre-intervention preparation (1-2 months): with the aim to mobilize the patients' resources for change Concentrated group intervention (2-5 days): interdisciplinary team - individually tailored training (further described below) Post-intervention follow-up (1 year): digital follow-up with the aim of integrate the changes into everyday living The concentrated intervention: The core intervention is based on trans-diagnostic features of the highly successful 4-day intervention for Obsessive Compulsive Disorder, namely: Initiate treatment when the patient is ready for change Focus on the behavioral patterns which maintain the disorder and help the patient to identify situations where they can choose to break the pattern ("micro-choices"). Assist the patient when they practice breaking the patterns. This may pertain to how they do physical training or to the way they walk, sit, eat, talk, take their medication and sleep, or to how they engage in social activities or take care of others. Use long sessions to ensure that they face a broad range of potential micro-choices Work side-by side with others going through an analogous pattern of change Prepare them for taking responsibility for integrating the change into every-day living Main outcomes will be Completion rates Patient satisfaction Changes to perception of illness Patient activation Secondary outcomes will be Level of functioning Qualitative description of participants' experiences
