Various Acoustic Rhinometry Measurements during Nasal Provocation of Patients with Perennial Allergic Rhinitis

Specific nasal provocation test with dermatophagoides pteronyssinus monitored by acoustic rhinometry in children and adolescents with allergic rhinitis and controls

Results Median age was 122 months (108 to 143 months) in controls and 142 months (117 to 156 months) in allergic rhinitis group. At the end of the NPT, the mean V5 fall was 5.7% (-8.7% to 4%) in controls and 22.8% (-24% to -20%) in allergic rhinitis group. None of the 15 controls and 88% (15 of 17 patients) of the allergic rhinitis group had a positive Dp NPT. Considering positive NPTs, 23.5% (...

Specific and non-specific nasal provocation tests in children with perennial allergic rhinitis.

BACKGROUND nasal provocation tests (NPT) have been extensively used in clinical practice to evaluate chronic rhinopathies, mainly allergic rhinitis (AR). METHODS we submitted 10 perennial AR children (aged from six to 15 years) to histamine (H), Dermatophagoides pteronyssinus (Dp) and Blomia tropicalis (Bt) NPT. All children were sensitized (positive skin prick test, mean wheal > 3 mm) to bot...

Segmental bronchial provocation induces nasal inflammation in allergic rhinitis patients.

Allergic rhinitis and asthma often coexist and share a genetic background. Pathophysiologic connections between the nose and lungs are still not entirely understood. This study was undertaken to compare allergic inflammation and clinical findings in the upper and lower airways after segmental bronchial provocation (SBP) in nonasthmatic allergic rhinitis patients. Eight nonasthmatic, grass polle...

Review of Symptoms Assessment During Nasal Allergen Provocation in Patients with Allergic Rhinitis

Background: Allergic rhinitis is the most prevalent allergic disease. Nasal provocation tests (NPTs) may be useful for its clinical diagnostic and therapy monitoring although they are mostly used in clinical research. However, the lack of standardisation in the symptoms assessed and the variety of instruments used make effective comparison between studies difficult. Objective: To review the pub...
