Drug management in chronic rhinosinusitis: identification of the needs.

Chronic rhinosinusitis (CRS) is a group of multifactorial diseases characterized by inflammation of the mucosa of the nose and paranasal sinuses with a history of at least 12 weeks of persistent symptoms despite maximal medical therapy. The precise role played by infection and immunoglobin E (IgE)-mediated hypersensitivity remains unclear. Diagnosis of CRS is based upon medical history, nasal endoscopy and computed tomography scan of the sinuses.

Levocetirizine improves health-related quality of life and health status in persistent allergic rhinitis.

Background: Allergic rhinitis is a chronic respiratory disorder with a detrimental impact on health-related quality of life (HRQOL) and health status. Enhancement and maintenance of patient function and well-being are therefore considered as essential.

Objective: To determine whether long-term treatment with levocetirizine 5mg improves HRQOL and health status in persistent allergic rhinitis (PER) patients assessed with RQLQ and SF-36 scales over a 6-month period.

Levocetirizine improves quality of life and reduces costs in long-term management of persistent allergic rhinitis.

Background: Allergic Rhinitis and its Impact on Asthma in collaboration with the World Health Organization initiative reclassified allergic rhinitis, like asthma, by duration and severity. The Xyzal in Persistent Rhinitis Trial is the first large, long-term clinical trial studying patients with persistent rhinitis as defined by Allergic Rhinitis and its Impact on Asthma.

Objectives: Two primary objectives were defined: comparison of the Rhinoconjunctivitis Quality of Life Questionnaire overall score and Total 5 Symptoms Score (rhinorrhea, sneezing, nasal congestion, and nasal and ocular pruritus) over a period of 4 weeks between levocetirizine 5 mg and placebo.
