Exhaled nitric oxide and quality of life in asthmatic teenagers
نویسندگان
چکیده
Methods Twenty-seven teenagers with asthma detected through the International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire answered the ISAAC rhinitis module and underwent spirometry, FeNO measurement and evaluation of QOL through Peadiatric Asthma Quality of Life Questionnaire (PAQLQ). Student t test and Kolmogorov – Smirnov test were applied for means comparison; association measures were performed through Pearson and Spearman correlation tests; a p-value<0.05 was considered to be statistically significant.

Level of Nitric Oxide in Bronchoalveolar Lavage Fluid of Asthmatic Mice Model
Background: Asthma is a chronic inflammatory disease with multifactorial and complicated mechanisms. Elevated level of exhaled Nitric Oxide (NO) in asthma and other inflammatory lung diseases has led to many studies examining NO as a potential marker of airway inflammation. Objective: This study was designed to determine the level of NO in Bronchoalveolar Lavage (BAL) fluid during early and l...
متن کاملQuality of life and inflammatory markers in mild asthma.
STUDY OBJECTIVES The aim of this study was to explore the relationship between quality of life and measures of asthma, such as lung function, reversibility to bronchodilation, exhaled nitric oxide (NO), and bronchial responsiveness to direct and indirect stimulus in patients with mild asthma in a primary care setting. PATIENTS AND MEASUREMENTS Seventy-seven asthmatic patients not treated with...
متن کاملThe effect of alcohol ingestion on exhaled nitric oxide.
The concentration of nitric oxide (NO) is increased in the exhaled air of patients with inflammatory lung diseases, including asthma, possibly reflecting cytokine-mediated chronic airway inflammation. Endogenous NO is generated from L-arginine by the action of several types of NO synthase (NOS). NOS have structural similarities with cytochrome P450 reductases. Alcohol decreases exhaled NO in an...
متن کاملNon-Asthmatic Patients Show Increased Exhaled Nitric Oxide Concentrations
OBJECTIVE Evaluate whether exhaled nitric oxide may serve as a marker of intraoperative bronchospasm. INTRODUCTION Intraoperative bronchospasm remains a challenging event during anesthesia. Previous studies in asthmatic patients suggest that exhaled nitric oxide may represent a noninvasive measure of airway inflammation. METHODS A total of 146,358 anesthesia information forms, which were re...
متن کاملAre exhaled nitric oxide measurements using the portable NIOX MINO repeatable?
BACKGROUND Exhaled nitric oxide is a non-invasive marker of airway inflammation and a portable analyser, the NIOX MINO (Aerocrine AB, Solna, Sweden), is now available. This study aimed to assess the reproducibility of the NIOX MINO measurements across age, sex and lung function for both absolute and categorical exhaled nitric oxide values in two distinct groups of children and teenagers.
