Abstract

It has been shown that endogenous nitric oxide (NO), measured in exhaled air, is increased in asthmatic subjects and after allergen challenge in sensitized animals. NO is also a paracrine molecule with some, though weak, bronchodilator effects. However, whether the amount of endogenous NO that originates in the lungs can reflect the degree of bronchial tone and airways calibre in asthmatic subjects has not yet been investigated. The aim of this study was, therefore, to determine whether NO production could be modified by acute changes of airways calibre in mild, nonatopic, asthmatic subjects. NO output was measured in the exhaled air of 14 steroid-free asthmatics, 8 steroid-treated asthmatics and 21 control subjects. In seven steroid-free asthmatics, exhaled NO was measured after methacholine challenge, and then after salbutamol-induced bronchial dilatation. Exhaled tidal breathing was collected for 30 s and NO in the exhaled air was measured with a chemiluminescence analyser. Both NO concentration and its output were significantly higher in the steroid-free asthmatic patients (15.6 +/- 1.5 parts per billion (ppb) and 6.3 +/- 0.7 nmol.min-1, respectively) as compared with the control subjects (8.9 +/- 1.0 ppb and 3.5 +/- 0.3 nmol.min-1, respectively; p < 0.001 for both) and with the steroid-treated asthmatic patients (11.3 +/- 3.3 ppb and 3.7 +/- 0.9 nmol.min-1, respectively; p < 0.05 for both). Neither methacholine-induced bronchial obstruction nor salbutamol-induced bronchial dilatation caused a significant change in exhaled NO. We conclude that NO production is higher in steroid-free than in steroid-treated asthmatics and in control subjects. Furthermore, NO production is not affected by acute pharmacologically-induced changes of airways calibre in asthmatic subjects. Our results suggest that NO production is a marker of airways inflammation rather than an endogenous modulator of bronchial tone in asthma.
