Active clinical trials for "Respiratory Tract Infections"

The ARIES Flu Assay is a real-time PCR based qualitative assay for the direct detection and differentiation of respiratory viral nucleic acid in nasopharyngeal swabs specimens. The objective of this study is to establish the diagnostic accuracy of ARIES Flu Assay.

The VRS (Respiratory Syncytial Virus) study group in Lyon is a working that aims to understand, predict and prevent the burden of disease caused by human respiratory syncytial virus (RSV) infection in infants. Incidence of RSV-associated hospitalization in the first year of life was estimated at 14.5 (95% CI 13.4-15.6) per 1000 births in a cohort study in Lyon, France. Related direct medical annual costs were estimated for this cohort at 364,269€, mostly attributed to children born during the RSV season (231,959€) and children born premature (108,673€). This study will combine existing hospital specimens and databases to determine the respective role of socio demographic factors, clinical risk factors, level of cord specific antibody at birth, and virus characteristic in the Respiratory Syncytial Virus (RSV) Hospitalization outcome in Infants. Regarding the introduction of a new RSV vaccine and RSV-specific neutralizing antibodies, these data are of prime importance to guide future vaccine policies.

In this prospective observational study, a quantitative and qualitative analysis of antibiotic prescriptions for presumed respiratory tract (super)infection in patients hospitalized on COVID-19 wards will be made. Drivers of antibiotic prescription for presumed respiratory tract infection in patients suspected of being infected with COVID-19 or with definite COVID-19 infections will be identified.

Project is designed as a comprehensive population-based epidemiological study in Upper-Silesian Conurbation (Poland) aiming at: analysis of available data on incidence and mortality due to COVID-19 and estimation of the occurrence of viral infection SARS-CoV-2 as revealed by the results of serological test (ELISA: IgM, IgG), with assessment of risk factors. The project's objectives are: to assess incidence and mortality due COVID-19 according to sex, age and coexisting diseases; to determine the level of potential "underdiagnosis" of the magnitude of COVID-19 mortality using vital statistics data for Upper-Silesian Conurbation; to assess the prevalence of SARS-CoV-2 based on the level of seropositivity in Upper-Silesian Conurbation; to identify host-related and environmental risk factors if the infection. Analysis of existing data will include monthly records on incidence and mortality over the period 01.01.2020-31.12.2020 and comparison of the findings with the monthly records of 2018 and 2019, for the same population. Cross-sectional epidemiological study will be located in three towne (Katowice, Sosnowiec, Gliwice). In each town a representative age-stratified sample of 2000 subjects will undergo questionnaire assessment and serological examination performed by serological test. The project corresponds with analogous population-based studies on COVID-19 in a number of countries and responds to the WHO recommendation in that field.

This is a multicentre, multinational, prospective observational investigation on ICU critically ill patients affected by nosocomial pneumonia, defined as: Out of ICU Hospital-acquired Pneumonia (HAP), Non-ventilator ICU-acquired Pneumonia (NV ICUAP), Ventilator associated pneumonia (VAP) Ventilator associated tracheobronchitis (VAT).

The human metapneumovirus (hMPV) was first described in 2001. It belongs to the paramyxovirus family and is genetically close to the Respiratory Syncytial Virus (RSV). hMPV has a seasonal epidemic pattern, between January to April. Clinical symptoms of hMPV infection include influenza-like illness (fever, asthenia and curvatures) associated with signs of respiratory tract infection. The incidence of hMPV infection is higher in children than in adults. In child pneumonia, hMPV is the third most frequent isolated pathogen (14 % of the subjects), after rhinovirus and RSV. In hospitalized adults, hMPV was detected in 6 to 8% of the subjects with lower respiratory tract and in 4 % of subjects with pneumonia. Clinical, radiological and biological features, as well as evolution course of hMPV infections have been mainly described in children. Clinical presentation of in adult seems polymorph, ranging from acute bronchitis or exacerbation of COPD to pneumonia. The frequency of viral-bacterial coinfection is unknown. Intensive care unit (ICU) admission may involve almost 1 for 10 patients. Elderly and immunocompromised subjects are probably high-risk subjects. Currently, treatment of hMPV infections is mainly symptomatic. However, several anti-RSV drugs that are currently in clinical development have demonstrated an activity against other paramyxoviridae in pre-clinical studies. Consequently, it seems necessary to better characterize hMPV infections in adult inpatients: presentation, course profile and risk factors for morbidity and mortality. These data would help clinicians to identify high risk patients, and consequently to choose those who could benefit from coming treatments. The French hMPV Study is observational prospective multicenter clinical study. The study population includes all consecutive adult inpatients with a community-acquired acute lower respiratory tract infection and a mPCR positive for hMPV on any respiratory sample. The primary objective is to describe the prognosis. The secondary objectives are i) to characterize clinical, radiological and biological features, ii) to describe the hospital course and the rate of ICU transfer; in ICU patients, to describe organ failures and supports, and iii) to describe the viral and/or bacterial coinfections. The primary endpoint is the number of subjects with a poor outcome (defined by the requirement for invasive mechanical ventilation and/or the death during the hospital stay).

The purpose of the study is to assess the number of severe, laboratory-confirmed influenza in children hospitalized to paediatric intensive care units. Furthermore, the proportion of these children from all children hospitalized to paediatric intensive care units with acute respiratory infections will be established.

Community-acquired pneumonia (CAP) is a heterogeneous disease causing great morbidity, mortality and health care burden globally. Typing methods for discriminating different clinical conditions of the same disease are essential to a better management of CAP. Traditional typing systems based separately on clinical manifestations (such as PSI and CURB-65), pathogens(bacterial types, virulence, drug resistance, etc) or host immune state (immunocompetent, immunocompromised or immunodeficiency). Thus, they are barely able to represent the real disease status nor to precisely predict the mortality. As the development of multi-omic technologies, the relatedness of different phenotypes at a molecular level have revolutionized our ability to differentiate among patients. Our study is aimed at establishing a novel molecular typing method of CAP. Multi-omic (including genomics, transcriptomes, and metabolisms) data obtained from enrolled CAP patients and isolated pathogens would be integrated analyzed and interpreted. Tthe investigators believe that an appropriate molecular typing method would lead to revolutionary changes in current arrangements of CAP.

Detection of gastrointestinal complications in mechanically ventilated critically ill patients and its relation to oropharyngeal and respiratory infections in relation to oropharyngeal and gastric PH.

The purpose of this study is two-fold. In the first phase, the goal is to characterize the stability of respiratory (nasal swab, nasopharyngeal swab, and throat swab; NS, NPS, TS) and stool (raw stool and rectal swab) specimens collected using various standard, medically established procedures with and without transport media and tested at various time points and under different temperature conditions, and also to look at variation between repeat sampling events. The intention is for these data to support decisions made by BioFire regarding the appropriate specimen type and handling guidelines for future tests. In the second phase of the study, collection and transport conditions identified in Phase 1 will be used to collect specimens for pilot performance evaluations of a new molecular diagnostic test.
