Active clinical trials for "Respiratory Tract Infections"

Greater efforts are needed to bring affordable, clean stoves and adaptive behavioral strategies to the millions of households worldwide that continue to burn solid cooking fuels using inefficient stoves. Two of the leading causes of infant mortality, preterm birth and pneumonia, are associated with high exposures to household air pollution during pregnancy and early infancy. The proposed study will assess the feasibility and acceptability of an introduced liquid petroleum gas stove, complemented by two alternative approaches to delivering tailored behavioral change interventions, among pregnant women and their neonates.

Background: Each Belgian winter season is characterized by a wave of influenza like and respiratory symptoms. Especially, the elderly people are more vulnerable to be infected by influenza, but also RSV. The recent COVID-19 pandemic and eventually a next wave, will increase the prevalence of influenza like and respiratory symptoms. Method: A multicentre non-commercial cohort study will be conducted in nursing home staff and residents during the Winter season 2020-2021. Objectives: Primary objective is the difference in incidence of influenza like and respiratory symptoms between cases (cases have evidence of past infection with SARS-CoV-2, referred to as Covid +) and controls (controls have no evidence of previous infection and are referred to as Covid -). The primary outcome analysis as well as the secondary outcome analyses will use two strata: nursing home staff and nursing home residents. The secondary objectives are the difference in incidence of COVID-19, influenza, RSV infections confirmed by PCR between cases and controls, to define a correlate of protection in the covid + group against re-infection with SARS-CoV-2 based on the study of the pre-existing antibody profile (antigen specificity, antibody type and antibody level) at the time of re-exposure. A multiplex assay will be used to assess the antibody profile. Finally, to study the COVID-19 disease severity (7 point WHO ordinal scale, this includes a.o. hospitalisation, mechanical ventilation need and ICU admission, mortality) based on the presence/absence of pre-existing antibodies and the pre-existing antibody profile. For other respiratory infections we will study the need for hospitalization and mortality.

Lower Respiratory Tract Infection (LRTI) is a frequent motive of consultation in General Practice. Cost, irradiation and availability of traditional imagery make it difficult to perform in every patient with suspected LRTI. The objective is to evaluate the performance of LUS realized by family physicians into the usual LRTI diagnostic pathway. This study is a prospective, interventional, multi-centric and open study conducted in 3 different centers by 15 General Practitioners (GP) in France. Patient complaining of dyspnea or cough were recruited from December 2019 to March 2020. GP received a training course by LUS expert before the study. The primary outcome measure was diagnosis modification after LUS. Secondary measures were therapeutic modification after LUS, decision of imagery prescription after LUS, decision of hospitalization or not after LUS, medical evolution and result of imagery initially prescribed by GP.

Viral respiratory infections are common worldwide. It has been suggested that nucleic acid amplification tests, enabling a rapid etiologic diagnosis, may be useful in reducing antibiotic prescriptions rates. The objective of this study was to evaluate if access to a multiplex real-time PCR method would have an impact on antibiotic prescriptions for acute respiratory tract infections (ARTIs), in primary care. Adult patients with respiratory tract infections will be prospectively included. Nasopharyngeal and throat swabs will be analyzed with a multiplex real-time PCR method, targeting 13 viruses and two bacteria. Samples will be collected during the winter season (October-April). Patients will be open-label randomised to receive a rapid result (the following day) or a delayed result (after 10+/-2 days). The investigators are planning to include approximately 400 patients. Prescription of antibiotics will be measured at initial visit as well as at a follow-up visit 10+/-2 days later. Primary endpoint is antibiotic prescription in the acute phase (initial visit) and secondary endpoint antibiotic treatment (ongoing or initiated) at follow-up visit. The hypohesis is that access to a method with the ability of providing a rapid etiologic diagnosis of respiratory infections will affect the use of antibiotics in outpatient care of adult patients with ARTI.

The aim of the study is to see if lozenges containing a low dose of interferon-alpha can prevent and/or reduce the severity of colds and flu. Starting about 1 month before the expected start of the winter colds and flu season in Perth, Australia, healthy volunteers will allow a lozenge containing interferon, or a lozenge containing no medicine (a placebo), to dissolve in their mouth once a day for 16 weeks. Blood tests at the start and end of treatment will determine whether interferon was able to prevent infections with cold/flu viruses. Once a week, volunteers will complete a survey about their cold/flu symptoms, medications taken, days of work missed, etc. to see if interferon was able to make their winter colds and flu less severe.

The investigators are aiming to learn more about respiratory infections in young children in the community. To prepare for a larger project, the investigators are conducting this study to get information about the best way to collect and transport respiratory specimens from young children. The investigators would like to test whether parents are more likely to collect a simple respiratory specimen themselves during a child's illness, compared to the likelihood of specimen collection when a home visit is made by a health care worker. Further, the investigators want to compare the likelihood a virus will be identified in both groups.

This is a stepped wedge, cluster randomized study of a clinical algorithm that includes point-of-care C-reactive protein testing to inform antibiotic treatment decisions by village health workers for children presenting with acute respiratory illness in the Bugoye sub-county of the Kasese District in southwestern Uganda. The purpose of this study is to assess the impact of the algorithm on antibiotic use.

The primary objective of this study is to estimate the impact of a self-monitoring tool (ChARM), used as a teaching/monitoring device, on the CHWs respiratory rate counting accuracy when assessing children under the age of 5 years with suspected pneumonia symptoms.

The purpose of this study is to assess the potential of probiotics in prevention of respiratory tract infections and their complications in children

The purpose of this study is to determine whether 14 days nutritional supplementation with Ready to use therapeutic Food (RUTF) or micronutrients alone to children having an infection will prevent malnutrition and reduce the frequency of morbidity.
