BACKGROUND Allergic rhinitis (AR) and related nasal congestion cause rhinitis-disturbed sleep (RDS). Intranasal corticosteroids reduce nasal congestion and improve sleep quality in AR but have not been extensively studied in RDS. OBJECTIVE To evaluate the efficacy of mometasone furoate nasal spray (NS) on nasal symptoms, nasal patency, sleep variables,(More)
BACKGROUND Elevated sputum eosinophil counts predict asthma exacerbations and responsiveness to inhaled corticosteroids but are impractical to measure in primary care. We investigated the relation between blood eosinophil count and prospective annual asthma outcomes for a large UK cohort. METHODS This historical cohort study used anonymised medical record(More)
BACKGROUND The ARIA (Allergic Rhinitis and its Impact on Asthma) guidelines proposed a classification for allergic rhinitis based on the duration of symptoms (intermittent or persistent) rather than on the time of allergen exposure (seasonal or perennial). There had been no placebo-controlled, randomized, clinical trial of desloratadine (DL) in patients(More)
BACKGROUND Patients report nasal congestion as the most bothersome seasonal allergic rhinitis (SAR) symptom. Measurement of this symptom in previous research has largely been based on subjective patient ratings. This study was designed to measure efficacy, onset, and duration of action of the corticosteroid mometasone furoate nasal spray (MFNS) on nasal(More)
BACKGROUND Intranasal steroids relieve nasal symptoms and ocular itch in allergic rhinitis. Itchy ear and palate are also common and bothersome symptoms but have received little attention in clinical trials of allergic rhinitis. OBJECTIVE To ascertain the efficacy of mometasone furoate nasal spray in alleviating itchy ear and palate in seasonal allergic(More)
PURPOSE Small airway changes and dysfunction contribute importantly to airway obstruction in chronic obstructive pulmonary disease (COPD), which is currently treated with inhaled corticosteroids (ICS) and long-acting bronchodilators at Global initiative for Obstructive Lung Disease (GOLD) grades 2-4. This retrospective matched cohort analysis compared(More)
AIMS Retrospective database study comparing upper and lower airway-related outcomes for patients with rhinitis and co-morbid asthma receiving mometasone furoate--an intranasal corticosteroid with low systemic bioavailability--or an oral antihistamine. METHODS 395 patients prescribed intranasal mometasone were matched on 10 demographic and(More)
Allergic rhinitis (AR) affects approximately 500 million people worldwide, and prevalence is increasing. Second-generation nonsedating antihistamines are first-line treatments for seasonal AR (SAR). This study was performed to evaluate early SAR symptom relief with second-generation antihistamines through a retrospective analysis of previously published(More)
BACKGROUND Allergic conjunctivitis (AC) is frequently associated with allergic rhinitis (AR) and affects up to 91% of patients with AR. Desloratadine, an orally administered, non-sedating second-generation antihistamine, has proven efficacy and safety in the control of nasal and non-nasal--including ocular--symptoms of AR. This randomized-controlled trial(More)
Successful delivery of inhalation medication to the lungs can be affected by the inhalation manoeuvre used. Conventional in-vitro testing of the emitted dose from a dry powder inhaler (DPI) uses a vacuum pump to simulate an inhalation. We have adapted this method by replacing the pump with patient inhalation profiles and an anatomical throat. Three(More)
