View clinical trials related to Covid19.
Filter by:Coronavirus (COVID-19) is a newly emerging zoonotic agent that emerged in December 2019 in China (2019-nCoV) as a Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV -2). Long COVID-19, or Post-Covid Syndrome or Long-term COVID-19, is a post-viral syndrome that persists after the acute infection has resolved. The most frequent symptoms of Lonf-term COVID are fatigue and dyspnea. But two classes of symptoms have been received scientific attention: the musculoskeletal pain and oral complaints related to Long COVID, mainly xerostomia and burning mouth. Photobiomodulation (PBM) therapy is often used for oral diseases and presents itself as a non-invasive, low-cost, safe therapy that has benefits in relation to the quality of life of patients with xerostomia. This study aims to investigate the clinical effectiveness of the use of a Photobiomodulation protocol in the treatment xerostomia and oral complaints related to Long-Covid. This will be a single-center, randomized, controlled, blinded clinical trial that will involve patients with Long COVID in follow-up at the Medical and Multiprofessional outpatient clinic of University Nove de Julho (UNINOVE) which remained hospitalized with COVID-19 at Lydia Storópoli Universitarian Hospital during the year 2022 and who were discharged from the inpatient treatment from January to December 2022. All those patients presenting xerostomia, burning mouth or oral complaints related to Long Covid will be randomized into 2 groups: PBM Group (standard rehabilitation treatment for Long COVID and xerostomia + PBM therapy) or PBM placebo group (standard rehabilitation treatment for Long COVID and xerostomia + placebo PBM therapy). PBM consists of the application of Red LED on the 3 pairs of major salivary glands (parotid, submandibular and sublingual) extraorally, transcutaneously, 3 J/cm2, for 36 seconds, twice a week for 06 weeks. Functional and quality of life evaluations will be perform pre and post therapy period.
Common side effects of corona virus disease 2019 (COVID-19) include disruptions in taste and smell function, which may persist for prolonged periods of time following recovery and resolution of COVID-19 infection. These disruptions not only reduce the hedonic pleasure derived from eating, but may also be detrimental to quality of life and could pose additional health risks (malnutrition) among patients with chronic illness or those enduring long-term complications from their previous COVID-19 infection. Previous studies conducted among patients with cancer experiencing taste and smell abnormalities have indicated improvement in taste and smell function following daily lactoferrin supplementation. Lactoferrin is a natural transferrin protein that scavenges and chelates iron byproducts produced as a function of lipid oxidation in the oral cavity following inflammation, infection, or toxicity of chemosensory tissues. The purpose of this pilot investigation is to assess the feasibility and preliminary effectiveness of lactoferrin supplementation (750mg per day for 30 days) for the treatment of taste and smell disturbances following COVID-19 infection. Approximately 40 patients who experienced disruptions in taste and smell following infection with COVID-19 will be recruited. Participants will complete baseline assessments (questionnaires, blood draw) and will be given 90 lactoferrin tablets (provided by Jarrow Formulas) in order to take 3 tablets per day for 30 days.
About 15,000 to 25,000 subjects will be screened. Their information will be collected, venous blood will be sampled, their serum antibody levels will be detected, and the incidence of COVID-19 wil be followed up.
A Phase 3 Study to Evaluate the Efficacy and Safety of QLS1128 Orally in Symptomatic Participants With Mild to Moderate COVID-19
The primary objective of this study is to identify immunometabolic signatures associated with Long COVID in plasma and peripheral blood mononuclear cells (PBMC).
The aim of the first study is to investigate how often a long Covid syndrome occurs after an inpatient rehabilitation due to previous hospitalization because of after acute Covid and whether there might be a connection with the severity during acute illness. 3 clusters of acute cases have been identified to be studied with regard to the long-term symptoms 1. Mild course (medication, oxygen) 2. Moderate course (IPS-IMC with NIV but without intubation) 3. Severe course (intubation) The aim of the second study is to use a catamnestic survey and subsequent evaluation of the information to gain an insight into the existing functional deficits relevant to everyday life and restriction of the ability to participate in the workplace after rehabilitation treatment. The assessment of functional deficits is carried out in relation to: 1. Deficits in everyday skills (ADLs) 2. Restrictions in the ability to participate in the profession.
This trial adopts a single-center, single-dose, single-period, non-randomized, open-label study design. It is planned to enroll 6~8 healthy male subjects, and each subject receives single oral administration of drug solution containing 600mg/approximately 100µCi [14C]STI-1558 under fasting conditions on trial D1. The whole blood, plasma, urine and stool samples are collected at specified time points/intervals during the trial. The pharmacokinetic parameters of the total radioactivity in plasma and whole blood, the material concentration ratios of the total radioactivity in plasma and whole blood, and the material balances are obtained by testing the total radioactivity of [14C]STI-1558 in plasma, whole blood, urine and feces. Meanwhile, using isotope tracer and mass spectrometry techniques, the main pathways and characteristics of metabolism and elimination of STI-1558 in humans are obtained through the quantification of radioactive metabolite profiles and the structure identification of the main metabolites in plasma, urine and feces of the subjects. The entire duration of trial is expected to be 5 months.
This is a clinical study evaluating the safety, tolerability, pharmacokinetic (PK) characteristics and immunogenicity of HH-120 nasal spray in healthy subjects. This study is divided into two parts: Part A is of open-label design and mainly aims to assess the local distribution and PK in nasal cavity of HH-120 nasal spray, subjects from 10 cohorts are sequentially enrolled to perform either nasal endoscopic examination or nasal/ nasopharyngeal samples collection at different time points post administration. Part B mainly aims to assess the safety, systematic pharmacokinetic and immunogenicity after multiple dosing of HH-120 nasal spray, subjects are randomly assigned (3:1) to HH-120 and placebo groups.
Coronavirus disease 2019 (COVID-19) infection leads to significant respiratory that have negative impact on function and quality of life (QoL). Breathing exercises are effective and important in patients with COVID-19.
At present, most studies mainly focussed on severe patients, and there was no comparison of symptom differences between AR patients and healthy people with mild infection to evaluate the symptoms of AR patients during infection and to provide preventive treatment in advance. So this experiment was designed.
