Recently, it is claimed that the usage of the intranasal glucocorticosteroids alone, instead of H1-antihistamines + intranasal glucocorticosteroids, reduces the complaints in moderate-to-severe seasonal allergic rhinitis (SAR). This study aims to evaluate the efficacy of the intranasal glucocorticosteroids alone during the pollen season by using objective and subjective parameters. Twenty-four patients (mean age, 12.17 +/- 2.26 years) with SAR sensitive to pollen are included in this study. The patients were divided into two groups randomly. Twelve patients in group I were given H1-antihistamine (loratadine) + intranasal glucocorticosteroid (mometasone furoate), and 12 patients in group II were given only intranasal glucocorticosteroid (mometasone furoate) for 12 weeks. To evaluate the results, subjective parameters (daytime nasal symptoms score, daytime eye symptoms score, and nighttime symptoms score) and objective parameters (nasal smear, nasal peak inspiratory flow [NPIF], and nasal biopsy) are used. With regard to the baseline data, it was observed that both groups had a significant decrease in total symptom score (p < 0.01), a significant increase in NPIF values (p < 0.01), and a significant decrease in the number of eosinophils in both nasal smear and biopsy (p < 0.01) after treatment. Comparing groups I and II in terms of treatment success, the improvement in daytime nasal symptoms score (p < 0.01 versus p < 0.01), daytime eye symptoms score (p < 0.01 versus p < 0.01), and total symptom score (p < 0.versus p < 0.01) was not different. However, there was a significant improvement in nighttime symptoms score between groups I and II (p < 0.01 versus p > 0.05). Furthermore, NPIF and nasal biopsy findings did not differ between groups (p > 0.05). The usage of H1-antihistamine + intranasal glucocorticosteroid has no superiority over the administration of intranasal glucocorticosteroid alone for treatment of SAR in pollen season. However, this finding needs to be confirmed in larger series studies.
