Filter by:The main objective is to investigate the incidence of Respiratory Tract Infections (RTIs) and antibiotic prescriptions in children and during pregnancy, the different drugs chosen by their doctors according to diagnosis, and compliance by patients. Further to investigate the possible effect of antibiotic use during pregnancy on RTIs and antibiotics and respiratory drug prescriptions in children the first two years after birth. Specific study objectives: - RTIs and antibiotic prescriptions in pre-school children - Frequency of diagnoses and antibiotic prescriptions - The proportion of broad spectrum antibiotics chosen - Prescription patterns and treatment compliance during pregnancy - Incidence of diagnoses, compared with not pregnant patients - Choice of antibiotics in RTIs - Prescription collection from pharmacies - Antibiotics and respiratory medication in children aged 0-2 yrs - Compare prevalence in children of mothers with frequent RTIs/antibiotic prescriptions during pregnancy and prevalence in children of mothers with few or no consultations during pregnancy - Incidence of wheezing and asthma diagnoses and incidence og respiratory prescription drugs when the mother has received antibiotics in pregnancy
The aim of this post-marketing observational study (PMOS) is to describe the relief of symptoms, tolerability and compliance of treatment with Klacid®SR in a dose 1000 mg once daily in patients with lower respiratory tract infection or in patients with acute exacerbation of chronic bronchitis (AECB) or mild community-acquired pneumonia (CAP).
Respiratory tract infections are the most common indication for antibiotic prescribing in primary care. Several studies have shown a strong relationship between antibiotic use and bacterial resistance. The aim of this trial was to assess the long-term effect of a continuous education program on general practitioners antibiotic prescribing behaviour. 170 physicians were included in this study. Physicians randomized in the education group attended a two days seminar focused on evidence-based guidelines on antibiotic use in respiratory tract infections. The intervention was limited at physicians level and did not target the patients.
The goals of our study are to critically evaluate if a healthy population supplemented with Transfer factor experiences fewer incidences of colds and flu, or experience shorter duration of illness compared to an identical population taking placebo. In this study we will give either Transfer factor or a placebo to two groups of healthy adult men and women for a period of 7 weeks in a double-blind experimental design. The frequency and duration of colds and flu-like symptoms will be recorded during the course of the study. Saliva samples will be collected weekly and assessed for salivary IgA secretion rate. Data from this study will establish the efficacy of Transfer Factor to support a healthy immune system.
This study will test the role of high dose vitamin D supplementation in prevention of acute respiratory infection in older nursing home residents. The investigators hypothesize that residents on high dose vitamin D supplementation will have a lower incidence of acute respiratory infection that those on standard dose vitamin D supplementation.
To describe the relief of symptoms, tolerability, and compliance of treatment with Klacid® sustained release (SR) at a dose of 1000 mg once daily in patients with acute tracheitis, acute tracheobronchitis, acute bronchitis, or in patients with acute exacerbation of chronic bronchitis or mild community-acquired pneumonia. This postmarketing observational study is non-interventional and is being conducted in a prospective, single-arm, single-country, multicenter format. Klacid SR will be prescribed in usual manner in accordance with the terms of the local market authorization with regards to dose, population, and indication as well as with local guidelines.
The fraction of exhaled nitric oxide (feNO) in expired air is a reliable measure of airway inflammation. Some research experiments have demonstrated stimulation of nitric oxide production in respiratory epithelial cells infected with RSV. The principal aims are to determine if the fraction of exhaled nitric oxide (feNO) is elevated in hospitalized pediatric patients with viral lower respiratory illness and to determine if there is a difference in feNO level between RSV and non-RSV infection. NO may play a role in the association between RSV, airway reactivity, and airway inflammation. This is a prospective, pilot study that will noninvasively measure feNO in children 0-4 years of age admitted to Winthrop University Hospital, as well as controls (children in the same age range without respiratory conditions and who are well enough to perform the test). Hospitalized children will be tested for RSV (enzyme immunoassay (EIA) & DFA) and via direct fluorescent antigen technique (DFA) for influenza A & B, parainfluenza, human metapneumovirus and adenovirus. Method of feNO measurement will utilize the offline options for preschool children & infants appropriate for age as described in the 2005 Joint Statement of the American Thoracic Society & the European Respiratory Society when discussing tidal breathing techniques with uncontrolled flow rate Offline exhaled air can be collected via a mouthpiece or a face mask connected to a non-re-breathing valve that allows inspiration of NO-free air from an NO-inert reservoir to avoid contamination by ambient NO. Exhaled breath samples are collected into an NO-inert bag fitted with the expiratory port once a stable breathing pattern is present. The results of all 3 groups will be compared: control, RSV positive and RSV negative samples.
Patients with allergic rhinitis frequently present exacerbation of the atopic symptoms during viral infections of the upper respiratory tract. Also, allergic rhinitis makes the mucosa more reactive to infectious agents and potentiates mucus production. The combination of dexchlorpheniramine, pseudoephedrine and guaifenesin elicits antihistaminic, decongestant and expectorant effects. The study hypothesizes is that this product is superior to dexchlorpheniramine alone in the relief of allergic symptoms and in promoting mucus elimination in atopic patients with viral infections of the upper respiratory tract.
Klacid Granules for Oral Suspension provides short symptoms' recovery time in Thai children with lower respiratory tract infections.
The investigators hypothesize that Klacid modified release (MR) shortens symptom recovery time in Thai patients with upper or lower respiratory tract infections.
