Filter by:Inhaled steroids, in particular beclomethasone, are widely prescribed in Italy as symptomatic treatment of upper respiratory infections without evidence of efficacy. The purpose of this study is to evaluate the efficacy of beclomethasone (administered by nebuliser twice a day) in preventing viral wheezing in pre-school children who had had episodes in the preceding 12 months.
15 mg dextromethorphan hydrobromide will be better than placebo with respect to reducing the number of coughs over 6 hours and reducing the subjective severity of cough over 6 hours.
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.
This is a local, phase IV, open-label, randomized, head to head study of children aged 3 to 7 years. The objective of the study is to compare the efficacy of a single dose of both diclofenac potassium and nimesulide in the reduction of fever and pain secondary to upper respiratory tract infection.
The primary objective is to assess the immunogenicity and safety and tolerability of two consecutive doses of H5 VLP Influenza vaccine given 21 days apart, at three dose levels: in part A: 20 µg, 30 µg and 45 µg combined with Alhydrogel® 1%, or 45 µg without Alhydrogel®, compared to the placebo, (100mM phosphate buffer + 150mM NaCl + 0.01% Tween 80).
The purpose of this study is to evaluate the symptom impact of probiotic Lactobacillus rhamnosus GG during rhinovirus infection.
Background: The medical and economic burden of upper respiratory tract infections (URTIs) is extremely high, while prevention and treatment options are limited. Therefore, there is a constant need for new methods in order to significantly decrease such morbidity. Extensive evidence shows that vitamin D is associated with respiratory health, including in the prevention and treatment of URTIs. Competitive swimmers have a high prevalence of URTIs, and can serve as a model for research in this field. The study hypothesis is that vitamin D supplementation to young swimmers with low vitamin D levels will reduce the frequency, length, and severity of URTIs and their accompanying functional impairment, while improving cellular immune function and physical function. Methods: After screening 100 competitive adolescent swimmers to obtain ~60 with low serum levels of vitamin D, this study group will be randomized to receive either vitamin D supplementation (2000 IU/d) or placebo, given in a double blinded fashion for three months. Participants will fill a daily questionnaire regarding frequency, length and severity of URTIs symptoms and functional impairment. Blood will be drawn to evaluate changes in vitamin D status (25(OH)D) and immune function among study participants at the beginning of the study and after supplementation. Physical function on land and in water will also be assessed. Expected results: Increase in serum 25(OH)D levels following supplementation will significantly decrease the frequency, length and severity of URTI's and their functional impairment, while enhancing the cellular immune system function and physical capacity.
Respiratory infections have a high associated morbidity and mortality, especially in immunocompromised patients. To initiate effective treatment of respiratory infections, it is essential that a rapid and thorough laboratory analysis of respiratory specimens be performed, given the wide range of pulmonary pathogens that can be detected in this population. Conventional microbiology is time-consuming and cumbersome, and the capability of local laboratories to assess specimens for rare or unusual pathogens is often limited. This study will evaluate if a newer technology can be effectively utilized in the identification of a broader range of infectious agents relative to conventional procedures. Resequencing Pathogen Microarray (RPM) technology developed by TessArae , LLC which ceased operations in July 2014) uses a microarray chip to identify multiple pathogens in a clinical specimen. The technology has had limited clinical application, but early studies have shown its effectiveness in accurately identifying a large number of viral and bacterial organisms. In contrast to conventional microbiological procedures based on phenotypic traits (growth characteristic and enzymatic activity), this is microarray utilizes DNA sequence analysis to detect and identify the species, serotype/subtype, or strain of the infectious agent. Aliquots of respiratory specimens (initially, specimens collected by bronchoalveolar lavage, BAL) from 200 patients at the NIH Clinical Center and the Washington Hospital Center will be analyzed using the customized microarray chip. The specimens will be collected as part of the patients routine clinical care. The results of the TessArray microarray analysis will not be available to the clinician and therefore will not have any effect on the clinical care of the patients. The results of the microarray analysis from each site will be compared to that site s clinical laboratory results, and the data will be analyzed by site.
1. Do paper-based and web-based intervention modelling experiments (the methodology we are developing) identify the same predictors of GP behaviour regarding prescribing of antibiotics for upper respiratory tract infections? 2. Can a web-based IME system provide trialists with richer and more predictive information upon which to base the development of behavioural change interventions than paper-based IME systems?
The excessive use of outpatient antibiotics in the pediatric population has contributed to the rapid development of resistance in many strains of Streptococcus pneumoniae. Research has shown that community-based interventions may have a modest impact on reducing the injudicious use of antibiotics in children. However, since the actual prescribing of antibiotics is done by physicians and research has shown that physician-parent communication patterns during pediatric visits for acute respiratory tract infections (ARTI) strongly influence antibiotic prescription rate, it is crucial to develop effective interventions aimed specifically at them. The overall goal of this study is to improve physician-parent communication patterns during visits for pediatric ARTI and, ultimately, to decrease rates of antibiotic prescribing for these illnesses in children.
