Background We previously reported a higher prevalence of nasal obstructive disorders (NOD) in pediatric patients with persistent allergic rhinitis (PER) not responding to medical treatment. The aim of this study was to determine the impact of NOD on quality of life (QoL) in this population. Methods Real-life prospective study including 142 patients (41 children, 6-11 years old and 101 adolescents, 12-17 years old) with moderate and severe PER. After 2 months of medical treatment (intranasal steroids and antihistamines), patients were asked whether their symptoms had improved (yes/no) and classified accordingly in R, responders and NR, non-responders. Nasal symptoms (visual analog scale, VAS), NOD (nasal endoscopy), and QoL (PRQLQ, AdolQRLQ) were also assessed. Results Sixty-nine adolescents and 24 children were included in the NR group. NR presented worse QoL overall scores in adolescents (3.16±1.1 vs 1.63±0.99; P=.00001) and children (2.19±0.82 vs 1.51±0.77, P=.02). Medical treatment failure was associated with worse outcomes in QoL (adolescents OR: 1.6, P<.0001; children OR: 1.04, P=.036). Female adolescents presented worse QoL scores than males (3.19 vs 2.36, P=.001). The presence of obstructive septal deviation (OR: 1.02, P=.005), obstructive turbinate hyperplasia (OR: 1.03, P=.0006), and coexistence of both (OR=2.06, P=.001) was associated with worse QoL in adolescents. A strong and highly significant correlation was found between nasal symptoms VAS and QoL. Conclusion The presence of NOD, particularly in adolescents, is associated with poor QoL outcomes. Assessment of NOD in pediatric PER should be considered an essential approach to determine the response to treatment and its impact on patient's QoL. [ABSTRACT FROM AUTHOR]

Background Allergic rhinitis ( AR) is the most common chronic disease among children. To characterize the disease, a modified classification of severity (m- ARIA) has recently been validated in AR children. When medical treatment fails, surgery for nasal obstructive disorders ( NOD) may be a therapeutic option. Our objective was to assess the prevalence of NOD and their influence in medical treatment response among children with persistent AR ( PER). Methods In a prospective, real-life study, 130 paediatric PER patients (13.1 ± 2.8 years, females 31.5%, severe rhinitis 49%) referred from Allergy to ENT department were assessed for their response (R, responders; NR, non-responders) to medical treatment (intranasal steroids and antihistamines or antileukotrienes) by direct questioning and nasal symptom visual analogue scale, the presence of NOD (septal deformity, turbinate enlargement and adenoidal hyperplasia), comorbidities, nasal symptoms, rhinitis severity (modified ARIA criterion) and asthma control (International Consensus On Pediatric Asthma criterion). Results After 2 months of treatment, the NR group presented a higher prevalence of obstructive septal deformity and severe inferior turbinate enlargement when compared with the R group. Higher septal deformity and turbinate enlargement scores were strongly associated with treatment refractoriness. The prevalence of severe PER was also higher for the NR group. Higher asthma control scores were associated with the probability of treatment-induced improvement. Conclusions In paediatric PER patients, medical therapy refractoriness was associated with NOD, mainly septal deformity and turbinate enlargement. In those patients, ENT examination will facilitate an early NOD diagnosis in order to indicate potential corrective surgery. [ABSTRACT FROM AUTHOR]

Background The objective of the OLFAPEDRIAL study was to assess the olfactory dysfunction in allergic paediatric population, which has been scarcely studied. Methods Observational, cross-sectional and multicentre study evaluated the sense of smell in untreated allergic rhinitis ( AR) paediatric patients aged 6-12 years. Results Forty-four per cent (551 of 1260) of children with AR reported smell dysfunction, with both loss of smell frequency (52.1%, p < 0.001) and intensity (0.75 ± 0.84, p < 0.0001) being more frequent in patients with persistent than intermittent AR (38.0% and 0.51 ± 0.73, respectively). In addition, both loss of smell frequency and intensity increased according to disease severity (m- ARIA classification) but always being significantly higher in persistent (p < 0.0001) than in intermittent AR. Conclusions Children with allergic rhinitis present a mild-moderate loss of smell frequency and intensity which is clearly related to the disease duration and severity. The loss of smell can be considered, as in adults, a clinical marker of disease severity. [ABSTRACT FROM AUTHOR]
