Objective: This study was conducted to
investigate nasal nitric oxide (nNO) and its metabolites nasal
nitrite-nitrate (nNOx) in patients with allergic rhinitis (AR), the
effects of two different drugs (oral antihistamine and intranasal
steroid) on nNOx and the presence of a correlation between nNOx and
clinical parameters.
Methods: Sixty
patients with active symptoms of perennial AR and 25 healthy adults as a
control group were enrolled. The patients were randomized into two
groups. Half of the patients received fexofenadine 1x120 mg/day orally,
and the other half received triamcinolone acetonide 1x2 puff/day
intranasally for one month. The amount of nNOx in nasal lavage fluid was
measured by using a commercially available kit and the photometric
endpoint determination method.
Results:
Pre-treatment levels of NOx in the nasal lavage fluids (1.92± 1.20 mg/l)
of patients with AR were found to be significantly higher when compared
with nasal lavage fluid NOx levels of healthy adults (1.38±0.78 mg/l)
(p=0.04). The post-treatment nNOx level (1.52±0.85 mg/l) was
significantly lower when compared with the pre-treatment value
(p=0.028).
Conclusion:
Nasal nitric oxide metabolites were shown to be good biomarkers for AR,
and that oral fexofenadine significantly decreased nNOx levels.
