Poor sleep is highly associated with house dust mite allergic rhinitis in adults and children.

ABSTRACT: Sleep disorders are often underreported to physicians by patients with allergies. This study aimed to characterize the sleep disorders associated with respiratory allergy to house dust mites (HDM) at the time of initiation of sublingual allergen immunotherapy (SLIT) in routine clinical practice.This prospective, cross-sectional, observational study was conducted between November 2014 and March 2015 at 189 French trial sites and included 1750 participants suffering from HDM allergy who were initiating SLIT. Participants aged less than 5 years old and those who had previously started an allergen immunotherapy (AIT) for HDM allergy were not enrolled in the study. Sleep disorders were assessed by self-administered questionnaires: the Epworth Sleepiness Scale (ESS), the Insomnia Severity Index (ISI) and a modified version of the Hotel Dieu-42 (HD-42) sleep disorder questionnaire. Logistic regression models adjusted for obesity, smoking status, asthma control and nasal obstruction were used to study the relationship between allergic rhinitis (AR) classification and sleep disorders/complaints.Of the 1786 participants enrolled, 1750 (907 adults and 843 children) composed the analysis population. The majority of participants (73.5% of adults and 65.8% of children) reported that their sleep disorders had prompted them to consult their physician. The most commonly observed sleep complaints were poor-quality sleep (50.3% of adults and 37.3% of children), snoring (48.1 and 41.4%, respectively) and nocturnal awakening (37.6 and 28.2%, respectively). Difficulties falling asleep were reported by 27.0% of adults and 24.7% of children. Adults and children suffering from severe persistent AR experienced sleep complaints significantly more often than participants with intermittent or mild persistent AR.This study highlights the high frequency of sleep disorders and their significant impact on patients with AR induced by HDM, in particular when AR is persistent and severe. Consequently, asking allergic patients about the quality of their sleep appears to be important, especially when the patient has persistent and severe AR.

Project description:BackgroundOne of the important pathogeneses of eustachian tube dysfunction (ETD) is nasal inflammatory disease. The prevalence of allergic rhinitis (AR) in adults ranges from 10 to 30% worldwide. However, research on the status of eustachian tubes in AR patients is still very limited.MethodsThis prospective controlled cross-sectional study recruited 59 volunteers and 59 patients with AR from Sun Yat-sen Memorial Hospital. Visual analogue scale (VAS) scores for AR symptoms and seven-item Eustachian Tube Dysfunction Questionnaire (ETDQ-7) scores were collected for both groups. Nasal endoscopy, tympanography and eustachian tube pressure measurement (tubomanometry, TMM) were used for objective assessment. All AR patients underwent 1 month of treatment with mometasone furoate nasal spray and oral loratadine. Then, the nasal condition and eustachian tube status were again evaluated.ResultsTMM examination revealed that 22 patients (39 ears, 33.1%) among the AR patients and 5 healthy controls (7 ears, 5.9%) had abnormal eustachian pressure. Twenty-two AR patients (37.3%) and 9 healthy controls had an ETDQ-7 score ≥ 15. With regard to nasal symptoms of AR, the VAS scores of nasal obstruction were correlated with the ETDQ-7 scores, and the correlation coefficient was r = 0.5124 (p < 0.0001). Nasal endoscopic scores were also positively correlated with ETDQ-7 scores, with a correlation coefficient of 0.7328 (p < 0.0001). After 1 month of treatment, VAS scores of nasal symptoms, endoscopic scores and ETDQ-7 scores were significantly decreased in AR patients (p < 0.0001), and TMM examination also suggested that eustachian tube function was significantly improved after treatment (p < 0.0001).ConclusionsAR patients, especially those with severe nasal obstruction, could have ETD. The local conditions of the pharyngeal orifices of the eustachian tubes are closely related to the symptoms of ETD. After treatment with nasal glucocorticoids and oral antihistamines, eustachian tube function can significantly improve as nasal symptoms subside.Trial registration Chinese Clinical Trial Registery (ChiCTR2000029071) Registered 12 January 2020-Retrospectively registered, http://www.chictr.org.cn/edit.aspx?pid=48328&htm=4.

Project description:BackgroundThe natural history of allergic sensitization in childhood, and its impact on allergic disease development, needs to be clarified. This study aims to identify allergic sensitization and morbidity patterns during the first 8 years of life.MethodsThe study was conducted in the on-going population-based prospective Pollution and Asthma Risk: an Infant Study (PARIS) birth cohort. Sensitization profiles were identified by k-means clustering based upon allergen-specific IgE levels measured at 18 months and 8/9 years. Allergic morbidity profiles were identified by latent class analysis based on symptoms, symptom severity, treatments, and lifetime doctor-diagnoses of asthma, allergic rhinitis, and atopic dermatitis and on lower respiratory infections before 2 years.ResultsFive sensitization and 5 allergic morbidity patterns were established in 714 children. Children not sensitized or with isolated and low allergen-specific sensitization were grouped together (76.8%). A profile of early and transient sensitization to foods that increased the risk of asthma later in childhood was identified (4.9%). Children strongly sensitized (≥3.5 kUA/L) to house dust mite at 8/9 years (9.0%) had the highest risk of asthma and allergic rhinitis. Finally, timothy grass pollen at 8/9 years sensitization profile (5.3%) was related to respiratory allergic diseases, as was early onset and persistent sensitization profile (4.1%), this latter being also strongly associated with atopic dermatitis.Conclusions & clinical relevanceWe show that accurate assessment of the risk of allergic disease should rely on earliness and multiplicity of sensitization, involved allergens, and allergen-specific IgE levels, and not considering solely allergic sensitization as a dichotomous variable (allergen-specific IgE ≥0.35 kUA/L), as usually done. This is particularly striking for house dust mite. We are hopeful that, pending further confirmation in other populations, our findings will improve clinical practice as part of an approach to allergic disease prevention.
