Cold-induced rhinitis (CIR) is common among skiers and is perceived as a tr
oublesome disease. We studied the clinical characteristics of CIR in a popu
lation of skiers and we evaluated the effectiveness of ipratrophan bromide
nasal spray (IBNS) in relieving symptoms in a double-blind placebo-controll
ed fashion. By means of specific questionnaires, we evaluated 144 subjects
(69% men; mean age, 42.2 years). The prevalence of CIR was 48.6% and the di
stinctive symptom was rhinorrhea (96%), often severe. The prevalence of ato
py was higher in the CIR patients (chi (2); p = 0.004). Twenty-eight CIR su
bjects participated in a double-blind placebo-controlled cross-over trial f
or evaluating the effectiveness of IBNS (80 mug twice per day [b.i.d.]). Th
e severity of symptoms was assessed by a visual analog scale, and the numbe
r of cleaning tissues used also was evaluated. The actively treated group s
howed a significant improvement of rhinorrhea (p = 0.0007) and a reduction
in the number of cleaning tissues used (p = 0.0023). Only four mild local s
ide effects were reported. We conclude that IBNS could be regarded as an op
timal therapeutic option for treating CIR symptoms in skiers.
