Active clinical trials for "Respiratory Tract (Lung and Bronchial) Diseases"

The Therma COVID-19 Rapid Antigen Test is an in vitro rapid, lateral flow immunoassay intended for the qualitative detection of SARS-CoV-2 nucleocapsid protein antigens in human saliva specimens. This test is intended for near-patient use at the point-of-care or lay person, self-use in a non-laboratory or home setting using saliva samples from individuals with or without symptoms of COVID-19. The Therma COVID-19 Rapid Antigen Test will be compared to a Health Canada approved RT-PCR COVID-19 test. Nasopharyngeal (for RT-PCR) samples will be collected at a COVID-19 Testing centre and saliva (for the rapid antigen test) samples will be collected and compared. The prospective, observational, feasibility study will test 300 participants to establish the performance characteristics of the test on saliva specimens.

The purpose of this study is to assess immune response of end stage renal failure patients after Covid 19 vaccination

Lung Ultrasound (LUS) has been revealing an extremely useful tool to identify and monitor complications from Sars-COV-2 disease. Recently, a research group has proposed a score, named LUS Score, able to optimize the use of this diagnostic technique. LUS Score is computed analyzing chest posterior and lateral spaces, considering the number of artefacts generated by the inflammed interstitium (B lines), the characteristics of the pleural line and the presence or not of consolidation areas. The comparison between LUS and chest tomography (CT), the current gold standard for the diagnosis of interstitial pneumonia by COVID-19, has confirmed from the preliminary data, the reliability of such technique. Hence, the validation on a really large sample size of the ultrasound tool performed by dedicated personnel with high expertise, may allow the validation both in the clinical practice and in emergency and ordinary wards.

200 participants should be included in the study. There will be three groups: 100 participants with a severe course of the disease 3 months ago, 50 asymptomatic carriers of coronavirus infection 3 months ago and 50 people who were in close contact with patients with confirmed coronavirus infection 3 months ago, but not sick and without antibodies to SARS-CoV-2. The study consists of two visits. At the first visit, after signing the consent to participate in the study, a screening examination will be performed to assess the criteria for inclusion and exclusion in the study. At the second visit, patients who meet the inclusion criteria and do not have exclusion criteria will undergo clinical and instrumental examination, and biological samples will be collected for laboratory testing. The aim of the study is to determine the most significant clinical and laboratory markers of the severity of the outcomes in the period of convalescence of the new coronavirus infection COVID-19. Clinical and laboratory indicators, the number and severity of signs of postcovid syndrome as well as pathological changes in lung tissue according to CT data in the group with covid pneumonia and indicators of immune status, hemostasis, endothelial dysfunction, inflammation, metabolism will be assessed.

The aim of this study is to check for the presence of COVID 19 antibodies [Covid-19, GAD-65, IA-2, ICA] in the blood of laboring women who have been exposed to either the virus itself or to the vaccine during pregnancy . The same test will be done on cord blood. Then the types of antibodies will be compared, between maternal and neonatal blood. The blood will be taken along with routine blood tests without additional punctures of Mother or Baby.

Chronic Respiratory Disease (CRD), particularly asthma and chronic obstructive pulmonary disorders (COPD) are leading causes of mortality and reduced quality of life due to its wide-reported association with other multi-morbidities.There is limited knowledge on the burden of CRD in the rural communities in Bangladesh due to poor awareness on the impact of CRD on quality of life and unavailability of diagnostic facilities due to weaker primary healthcare settings. The study aims to estimate the CRD burden in Bangladesh in a large representative population to draw the attention of policy makers to the creation of social awareness and improvement of primary healthcare infrastructure for respiratory disease in Bangladesh. The study is a prospective observational one in nature. The study will be implemented in Mirzapur, a rural sub-district of Tangail district in Bangladesh within the period of February to May 2021. A total of 981 participants will be enrolled from the study. Verbal consent will be taken initially. Participants who are assessed to be COVID-19 negative will be invited for a visit to the mobile clinic following national health guidelines to perform the spirometry. The study team will provide an information sheet (written in local language) that describes the study aim and objectives with potential risk benefits to the participants. All participants will be enrolled through written consent and satisfactory response to the patient information sheet. The Research Assistant (RA) will collect the relevant metadata such as demographics, information on risk factors, screening questionnaires relevant to asthma and COPD, reported health status and symptoms related to CRD etc. from the participant after obtaining the written consent. Data quality will be ensured by the Field Research Supervisor through checking all the collected information. The enrolled participants will undergo spirometry for the evaluation of their lung function. Spirometry will be collected by trained personnel and will be quality checked by an expert panel at CHRF. Repeated collection will take place in the event if the test results do not pass quality checking. Participant will also be invited to the study clinic within the next 10 days after assessment for any further clinical assessment that is deemed necessary by the study physician. The collected data and spirometry reports will be reviewed to evaluate the CRD patient in terms of their disease. The study will analyse the rate of CRD burden stratified by age, sex, and income group. The productivity loss will be measured in terms of work hours lost due to CRDs.

SARS-CoV-2 infection is characterized mainly by moderate/severe pneumonia associated with progressive endothelial damage and coagulopathy. Acute respiratory failure among COVID-19 occurs in 42% of patients with COVID-19 pneumonia, and 61-81% of patients requiring intensive care . Among the suggested treatments for the management of ARDS patients, prone position (PP) can be used as an adjuvant therapy for improving ventilation in these patients, as recommended in the Surviving Sepsis Campaign COVID-19 guidelines. Nevertheless, no data is currently available on application and feasibility of PP in invasively ventilated patients with COVID-19 on their outcomes.

This study propose to describe risk factors for acute and long term mortality of COVID 19 in patients up to 70 years old.

In this study, critically ill patients with highly suspected or confirmed COVID-19 will be included. Main goal is the identification of noncoding RNAs in COVID-19 associated organ dysfunction with an emphasis on acute kidney injury.

The Malaysian COVID-19 Anosmia Study is a nationwide multicentre observational study to investigate the prevalence and characteristics of olfactory and gustatory/taste disturbances in COVID-19 infection in Malaysia, and to evaluate the predictive value of screening for these symptoms in COVID-19 infection. This study consists of two phases: the first phase is a cross-sectional study and the second phase is a case-control study. The case-control study is described here (the cross-sectional study is described in a separate ClinicalTrials.gov record).
