NCT ID: NCT05301647 Completed - Quality of Life Clinical Trials

Mometasone Furoate Nasal Spray in Italian Children

Start date: June 20, 2019
Phase:
Study type: Observational

Objective Seasonal allergic rhinitis (SAR) is a common disease in childhood and characterized by type 2 inflammation, bothersome symptoms, and impaired quality of life (QoL). Intranasal corticosteroids are effective medications in managing SAR patients. In addition, mometasone furoate nasal spray (MFNS) is a well-known therapeutic option. However, the literature provided no data about its effects in European children with SAR. Thus this study addressed this unmet need.

NCT ID: NCT03039101 Completed - Nasal Allergy Clinical Trials

Leukotriene Antagonism in Recruitment of CD49d Expressing Neutrophils in Atopic Subjects

Start date: September 6, 2017
Phase: N/A
Study type: Interventional

The purpose of this study is to see if the recruitment of a certain cell type (the alpha 4 integrin (CD49d) expressing neutrophil) during a nasal allergen challenge can be inhibited by pretreatment with an FDA approved leukotriene antagonist (montelukast).

NCT ID: NCT01925729 Completed - Middle Ear Disease Clinical Trials

TransMEM Gas Exchange -- Project 1, Aim 2

Start date: October 1, 2013
Phase: Phase 1
Study type: Interventional

This study will determine if exposure to an allergy material (ragweed) or exposure to an allergic-symptom-provoking substance (histamine) and medications typically used to decongest the nose changes the rate of blood-flow in the lining of the middle-ear. Otitis media (the build-up of water-like fluid in the middle-ear airspace) may occur if the blood flow in the lining of the middle-ear is too high and may be prevented if a way could be found to lower the blood flow in persons susceptible to the disease. Middle-ear blood flow is measured indirectly by measuring the change in middle-ear pressure while a person breathes a gas mixture containing nitrous oxide ("laughing gas"). In this study, 4 groups of subjects will be entered and middle-ear pressure in persons breathing a mixture of 50% Oxygen, 50% Nitrous Oxide ("laughing gas")will be measured after exposure to one of four substances (ragweed, histamine,an oral decongestant, a decongestant nasal spray) and a fake medication (placebo) at separate test sessions. All subjects will have one set of 2 x-rays of the middle ears and mastoids. The group exposed to ragweed will require 3 study visits while the other 3 groups will have 2 study visits. From this information middle-ear blood flow will be calculated. This will help determine the relationship between what happens in the nose and what happens in the middle ear.
