Active clinical trials for "Respiratory Tract Infections"

This study was advocated by Institute of Basic Research in Clinical Medicine, China Academy of Chinese Medical Sciences in January 2013. The purpose of this study is to make a event monitoring to see whether Reduning injection is safe and the characteristic and mechanism of anaphylactic reaction used Reduning injection in hospitals in China.

Identifying multiorgan sequalae and complications through high quality, prospective matched controlled studies throughout the course of COVID-19 is important for the acute and long-term management of patients and for health systems' planning. Further, it is key to understand the link between acute illness and long term consequences particularly in those already living with other comorbidities such as cardiovascular diseases or cancer. Since the clinical presentation of COVID-19 can resemble a variety of common respiratory infections, describing the distribution of pathogens and the severity of clinical presentation associated with COVID-like illnesses (CLI) infections is important to generate a baseline clinical description by comparing potential long-term effects of PCR-confirmed COVID-19 to those following other respiratory infections. To gain a better understanding of the clinical burden on COVID-19 survivors we will undertake a comparative evaluation within a cohort of PCR-confirmed individuals with COVID-19 vs. those PCR-confirmed symptomatic individuals with other respiratory pathogens plus healthy individuals from the community. The results will inform strategies to prevent long term consequences; inform clinical management, interventional research, direct rehabilitation, and inform public health management to reduce overall morbidity and improve outcomes of COVID-19.

The purpose of the CircumVent Project is to evaluate the feasibility, adaptability and acceptability of a CPAP/O2 helmet solution for non-invasive ventilation among patients with COVID-19 and health workers in eight COVID-19 treatment and isolation centers in Nigeria.

The SARS-CoV2 virus causes severe or even fatal disease in a fraction of infected people. The clinical severity is based on a complicated pneumopathy with acute respiratory distress syndrome that can lead to multi-visceral failure. The underlying mechanism is a cytokinergic storm, an emerging facet of immunological dysregulation. This clinical trial is aimed to understand the mechanisms of this immunological dysregulation in order to identify therapeutic levers. The main objective is to understand the relationships between clinical severity, death or morbidity of resuscitation management, and immune status (i.e., immune pathways activated or not). Immune status will be investigated at many levels of organization (i.e., circulating leukocytes, cytokines and chemokines, transcripts). The secondary objectives are : to understand what is responsible for clinical severity, viral load, or immune activation; to highlight the consequences of immunological dysregulation on associated risks (i.e., immunosuppression leading to the emergence of infectious comorbidities) as well as the functioning of neurotransmission through metabolic pathway diversions. The impact of dysimmunity on these biological pathways will be assessed with a metabolomic analysis; to understand the mechanisms of vulnerability related to the field. Moreover, while co-morbidities are likely to be a risk factor for severe disease progression, there are many situations in which they do not occur. Stress, with its neurovegetative and endocrinological dimensions, modulates the immune response. It is essential to know whether the stress response plays a role in immunological dysregulation. This analysis is a prerequisite for understanding the conditions of treatment with glucocorticoids. Angiotensin converting enzyme type 2 (ACE2) also plays a likely role in host viral infection. It is also thought to play an important role in the emergence of severe syndromes by affecting the quality of vascular response.

Recently, the emergence and rapid global dissemination of novel swine-origin influenza A virus (H1N1) with unique epidemiologic characteristics has heightened awareness and concern of this viral pathogen, and its potential for major disruption of both civil and military stability. Although advances in medical and scientific technologies have improved our basic understanding of respiratory disease, many questions about the epidemiology and immunology of ARI remain unanswered. This study plans to initiate a multi-site, multi-disciplinary research collaboration, termed the Acute Respiratory Infection Consortium (ARIC) for the purpose of studying the etiology, epidemiology and immunology of influenza-like illness (ILI) in order to describe the natural history and risk factors for disease, as well as the characteristics of the host immune response. At the core of the ARIC is the proposed observational, longitudinal study of the Natural History Study of ILI among active duty military members, healthy retirees, and their dependents recruited from both inpatient and outpatient settings of military treatment facilities (MTF) in the continental US to be followed for a total of four (4) visits over a 28-day period. Additionally, the investigators also propose to conduct a household-based study of influenza (Family Transmission Study) in which individuals who have a laboratory-confirmed influenza illness will be recruited and enrolled along with their family members for the purpose of studying transmission of influenza within households. Taken together, these studies will establish a longitudinal cohort of ILI among active duty members and their families, as well as a repository of biological specimens relevant to the epidemiology and immunology of infection. Ultimately, these studies will serve as a solid foundation on which future investigations of ARI epidemiology, treatment and prevention can be based.

The purpose of this feasibility study is to test a device which analyzes breath and may allow doctors and health professionals to immediately determine if an ill patient has a specific type of bacterial infection. This will allow a health professional to provide immediate targeted antibiotics to properly start treatment without delay.

This is a multicenter prospective collection of leftover respiratory tract secretions, paired blood and NP swabs, and clinical circumstances from pediatric HCT patients, followed by next generation genomic sequencing, transcriptome analysis, protein biomarker measurement, and statistical modeling.

The study consist of a retrospective analysis of the etiologies, investigations and outcomes of patients presenting between 2005 to 2010 with hemoptysis in a North-American Tertiary center.

Severe Acute Respiratory Infection (SARI) is defined by the World Health Organization (WHO) as acute respiratory infection with a history of fever ≥38°C and cough for less than 10 days duration that requires hospital admission. SARI-PREP is a multi-center consortium funded by the CDC Foundation being assembled with the goal of providing the infrastructure to rapidly collect prospective data on clinical risks and outcomes, hospital-level stress, and biologic specimens that will aid in the rapid development of diagnostic and treatment approaches. A current example of a form of SARI to be targeted by SARI-PREP is COVID-19 the acute respiratory infectious disease caused by SARS-CoV-2 infection. COVID-19 has a broad set of manifestations and severity with a subset of affected patients developing severe disease leading to respiratory failure and other forms of organ dysfunction. As with many outbreaks of novel viral pathogens causing SARI there was no efficacious therapeutic intervention at the beginning of the COVID-19 pandemic. Furthermore, while there is emerging knowledge of clinical risks for severe COVID-19, there remains a paucity of information about the viral dynamics and host responses that might indicate a patient is at high risk for poor outcomes. The COVID-19 pandemic will be the initial target of the SARI-PREP consortium with the overall goal of developing a multi-institutional collaborative network of Acute Care Hospitals that will rapidly enroll, sample, and follow patients admitted with severe COVID-19 and to develop research protocols to rapidly determine demographic, clinical, host molecular, virologic, and institutional correlates of outcome. Overall, the information gained from this effort will help to rapidly inform and improve clinical management of epidemic/pandemic SARI patients.
