Cell distribution and cytokine levels in induced sputum from healthy subjects and patients with asthma after using different nebulizer techniques.

ABSTRACT:

Background

Sputum induction is an important noninvasive method for analyzing bronchial inflammation in patients with asthma and other respiratory diseases. Most frequently, ultrasonic nebulizers are used for sputum induction, but breath-controlled nebulizers may target the small airways more efficiently. This treatment may produce a cell distribution similar to bronchoalveolar lavage (less neutrophils and more macrophages) and provide deeper insights into the underlying lung pathology. The goal of the study was to compare both types of nebulizer devices and their efficacy in inducing sputum to measure bronchial inflammation, i.e., cell composition and cytokines, in patients with mild allergic asthma and healthy controls.
