Active clinical trials for "Respiratory Tract Infections"

A randomized parallel-group two arm superiority trial with an allocation ratio 1:1, both participants and investigators blinded. The zinc lozenge that will be used in the study is a commercial product available from the University Pharmacy, Helsinki, Finland. The product is classified as a "medical device" and it is not regulated according to the jurisdiction for medicines. Each lozenge contains 13 mg elemental zinc as zinc acetate. The instruction in the commercial package for common cold patients is to dissolve slowly 6 lozenges per day in their mouth, which totals to 78 mg/day of elemental zinc, at most for 5 days. The same instruction will be used in this trial. The University Pharmacy prepared 200 placebo lozenge packages so that the placebo lozenges contain sucrose octaacetate, and they are similar with the zinc lozenges in visual appearance and in taste. 200 packages of zinc lozenges will be used as the active intervention. The packages will contain 30 lozenges (6 lozenges/day × 5 days). The packages of lozenges will be distributed to the enrolled participants in November 2017. The participants will be instructed to keep the package readily available so that, when they catch the common cold, they will find the package and they can start to take the lozenges according to the instructions. The participants will be instructed to start taking zinc lozenges as soon as they start to suffer from the first symptoms of the common cold. The participants will be instructed to take 6 lozenges daily over the time awake, evenly distributed, allowing the lozenge to dissolve in the mouth as slowly as possible. The duration of intervention is for the maximum of 5 days. If the symptoms disappear before 5 days, the participant may stop the usage of the lozenges. There will be no limitations for other treatments that participants wish to use for treating their colds. Participants will be requested to respond to a web-based symptom questionnaire daily from the first day of the treatment to the recovery from the common cold, or to a maximum of 2 weeks.

Randomized, Double-blind, Parellel, Multicenter, Active-controlled

The goal of this observational study is to compare the results of a serum biomarker called the MeMed BV®, which is approved to help differentiate between bacterial and viral respiratory infections, to clinical diagnoses of adult emergency department patients presenting with recent fever and signs or symptoms of a respiratory infection. Active participation is completed during the emergency department visit and includes drawing blood, obtaining a sputum sample, and answering survey questions.

Randomized, Open-label, Oral, Single-dose, two-Sequence, four-Period, crossover study

The objective of this trial is to determine whether certain subgroups of children with acute sinusitis exist in whom antibiotic therapy can be appropriately withheld.

The purpose of this research study is to explore the mechanism of action of Mucinex, an oral, over-the-counter, FDA approved expectorant in patients with acute respiratory tract infections.

Nursing home residents are frequently transferred to hospital for management of pneumonia. This often leads to hospital related complications and is a burden on the acute care health system. The purpose of this study is to assess whether managing residents with pneumonia and lower respiratory tract infection on site in the nursing home can reduce hospital admissions and can reduce complications and improve quality of life for residents. We have randomized residents with nursing home acquired pneumonia to on-site management, using a clinical pathway, versus usual care.

There is evidence that some types of probiotics play a role in alleviation of symptoms of acute respiratory tract infections and bursting immune response to respiratory and enteric viruses. Available data serves a rationale for the study exploring a role of nutritional support with probiotics in adult outpatients with COVID-19. Hypothesis of the study is that a proposed mixture of lactobacilli and bifidobacteria facilitate faster recovery from COVID-19 and enhance specific immune response to SARS-CoV-2 antigens.

A randomized controlled trial of a commercially available homeopathic cold remedy will be conducted. A total of 400 children, 2-5 years old, diagnosed with an upper respiratory tract infection will be randomized to receive either the homeopathic remedy or placebo. Parents of study children will administer 5 ml of the study medication up to 6 times per day as needed to treat cold symptoms. One hour after giving a dose the parent will rate change in symptoms (for up to the first 10 doses). In addition, parents will rate their child's overall symptom severity and functional status over the first 3 days of the cold. It is postulated that children receiving the active homeopathic remedy will have better symptom relief and that their symptom severity and functional status will improve more rapidly than those receiving placebo.

The aim of the study is to investigate whether the early introduction of maintenance bronchodilator therapy during an acute symptomatic episode of the disease shows benefits on the recovery of symptoms. It also represents an opportunity to identify COPD patients earlier in their disease state and start maintenance therapy, if appropriate.
