In 28 patients with SAR and 50 healthy study patients, the leukotrienes were measured during and after the pollen season by gas chromatography/mass spectrometry. Following seasonal and postseasonal median values were measured in patients with SAR in comparison with control patients: LTB4: 131 and 90 pg/mL vs 80 and 79 pg/mL, P < .001 and P = .03, respectively; LTE4: 122 and 86 pg/mL vs 76 and 74 pg/mL, P < .001and P = .02, respectively. Five months after the pollen season, the concentrations of LTB4 and LTE4 decreased with respect to their seasonal values (P < .001). The seasonal and postseasonal increases in LTB4 and LTE4 concentrations in EBC correlated significantly with the later increase in BRM.
