Is there an increased risk of otitis media in children with obstructive sleep apnea?

INTRODUCTION: The purpose of this study was to investigate the prevalence of otitis media and other otolaryngologic disorders in children with Obstructive Sleep Apnea (OSA) compared to those without OSA in a large cohort. METHODS: A retrospective cohort study was carried within the US Collaborative Network within TriNetX. The OSA group was defined by ICD-10 code G47.33 and non-OSA group excluded patients with OSA. Both groups were required to have a CPT code for an outpatient visit to act as a control: 99202-99215. Propensity score matching for age, sex, and race was performed. Prevalence of otitis media (ICD-10H65, H66), chronic otitis media (ICD-10H66.1, H66.2, H66.3, H65.2, H65.3, and H65.4), tympanostomy (CPT 69433, 69436), adenoidectomy (CPT 42830, 42831), tonsillectomy (CPT 42825, 42826), adenotonsillectomy (CPT 42820, 42821), and allergic rhinitis (ICD-10 J30.9) were compared in this cohort. RESULTS: Propensity score matching yielded 165,665 (M = 95949, F = 69901) patients with a mean age of 10.7 (SD = 4.07) for each cohort. Children with OSA were 1.27x and 3.86x more likely to be diagnosed with otitis media and chronic otitis media, respectively (P<.0001). They were 3.81x more likely to undergo a tympanostomy (P<.0001). Children with OSA were 4.1x, 18.2x, and 24.7x more likely undergo an adenoidectomy, tonsillectomy, and adenotonsillectomy, respectively (P<.0001). Children with OSA were also 2.03x as likely to have a diagnosis of allergic rhinitis (P<.0001). CONCLUSION: Children with OSA experience otitis media and related surgical intervention more than children without OSA. Since allergic rhinitis and adenoid hypertrophy are contributors to both OSA and AOM, their increased prevalence in children with OSA may explain their increased frequency of AOM.

Manifestation and associated factors of systemic and local allergy among patients with allergic fungal rhinosinusitis: An observational study.

Allergic fungal rhinosinusitis (AFRS) is a subtype of chronic rhinosinusitis, characterized by excessive immune responses to environmental molds or fungi. The diagnosis and classification of AFRS into systemic and local types remain clinically challenging due to overlapping characteristics. This study investigated the prevalence of AFRS, its manifestation and associated factors in systemic and local AFRS. A total of 200 patients diagnosed with fungal rhinosinusitis underwent both skin provocation tests (SPT) and nasal provocation tests (NPT) to confirm AFRS and classify systemic and local types. Patients were considered to have AFRS if either the SPT or NPT was positive. Among these, patients with systemic AFRS were those who had a SPT positive. Local AFRS was when patients had a negative SPT and a positive NPT. Medical history, serum total IgE level, nasal endoscopy examinations, and CT scans were also recorded. Most patients were female (65.8%), with a mean age of 55.6 years (SD = 14.4). Based on the SPT and NPT results, 31% of patients (n = 62) were diagnosed with AFRS. Among these, 54.8% (n = 34) had systemic AFRS, while 45.2% (n = 28) had local AFRS. Patients with AFRS exhibited significantly higher levels of total IgE, eosinophils, and more pronounced signs and symptoms compared to those without AFRS. However, no statistically significant differences were observed between patients with systemic AFRS and those with local AFRS. AFRS was prevalent in our study. Among patients with AFRS, both systemic AFRS and local AFRS were also prevalent. While allergic indicators and clinical presentations can aid in AFRS diagnosis, minimal distinctions were observed between systemic and local AFRS. A comprehensive assessment incorporating both local and systemic allergic responses through provocation tests, such as a combination of skin and nasal tests, is imperative for optimizing AFRS diagnosis and management.

Impact of allergic rhinitis on quality of life in patients with chronic rhinosinusitis.

OBJECTIVES: To evaluate the impact of allergic rhinitis (AR) on the quality of life (QoL) in patients with chronic rhinosinusitis (CRS). METHODS: Retrospective cross-sectional study of adult patients with CRS presenting to our clinic between August 2020 and February 2023 was performed. AR was diagnosed based on a positive skin or blood allergy test. Patients' characteristics, AR status, comorbidities, endoscopy scores, and SNOT-22 scores were collected. RESULTS: A total of 514 CRS patients were included, with 265 (51.6 %) patients with AR. CRS patients with AR were younger (p = 0.004), more likely to be female (p < 0.001), and more likely to have asthma (p < 0.001). Polyp status and endoscopy scores did not differ between patients with and without AR. Baseline SNOT-22 scores were slightly worse in the AR cohort (43.6 vs 38.7, p = 0.007), which was mainly secondary to rhinologic (p = 0.002), extrarhinologic (p = 0.007), and ear/facial (p = 0.007) subdomains. Worse rhinologic and extrarhinologic scores were associated with the presence of AR after adjusting for confounding variables (Coef = 1.55, p = 0.011; and Coef = 0.83, p = 0.021 respectively). CONCLUSION: The impact of allergic rhinitis on QoL is mainly on the nasal symptoms. Further studies should look at the role of AR on the QoL of different CRS endotypes; and at the role of AR-specific treatment, such as immunotherapy, on the QoL of patients with CRS.

Asthma and obstructive sleep apnea: Unveiling correlations and treatable traits for comprehensive care.

Asthma and obstructive sleep apnea (OSA) are common respiratory disorders. They share characteristics such as airway obstruction, poor sleep quality, and low quality of life. They are often present as comorbidities, along with obesity, gastroesophageal reflux disease (GERD), and allergic rhinitis (AR), which impacts the disease's control. In recent years, there has been discussion about the association between these conditions and their pathophysiological and clinical consequences, resulting in worse health outcomes, increased healthcare resource consumption, prolonged hospital stays, and increased morbidity and mortality. Some studies demonstrate that treatment with continuous positive airway pressure (CPAP) can have a beneficial effect on both pathologies. This review summarizes the existing evidence of the association between asthma and OSA at their pathophysiological, epidemiological, clinical, and therapeutic levels. It intends to raise awareness among healthcare professionals about these conditions and the need for further research.

Risk factors of sleep-disordered breathing and poor asthma control in children with asthma.

BACKGROUND: Sleep-disordered breathing (SDB) may lead to poor asthma control in children. OBJECTIVE: To identify risk factors of SDB in children with asthma and assess its impact on asthma control. METHODS: In this cross-sectional study, we collected data of outpatients with asthma at the Children's Hospital of Chongqing Medical University from June 2020 to August 2021. The Pediatric Sleep Questionnaire-Sleep-Related Breathing Disorder and the age-appropriate asthma control tests Childhood Asthma Control Test and Test for Respiratory and Asthma Control in Kids were completed. RESULTS: We enrolled 397 children with a male-to-female ratio of 1.7:1 and a mean age of 5.70 ± 2.53 years. The prevalence of SDB was 21.6%. Allergic rhinitis (odds ratio OR = 3.316), chronic tonsillitis (OR = 2.246), gastroesophageal reflux (OR = 7.518), adenoid hypertrophy (OR = 3.479), recurrent respiratory infections (OR = 2.195), and a family history of snoring (OR = 2.048) were risk factors for the development of combined SDB in children with asthma (p < 0.05). Asthma was poorly controlled in 19.6% of the children. SDB (OR = 2.391) and irregular medication use (OR = 2.571) were risk factors for poor asthma control (p < 0.05). CONCLUSIONS: Allergic rhinitis, chronic tonsillitis, gastroesophageal reflux, adenoid hypertrophy, recurrent respiratory infections, and a family history of snoring were independent risk factors for the development of SDB in children with asthma. SDB and irregular medication use were independent risk factors for poor asthma control.

Otolaryngologic sequelae of Ehlers Danlos Syndrome in pediatric patients.

OBJECTIVE: As outlined by the NIH, Ehlers Danlos Syndrome (EDS) is a group of hereditary connective tissue disorders characterized by skin hyperelasticity, joint hypermobility, atrophic scarring, and blood vessel fragility, with no otolaryngological criteria for diagnosis. We aimed to compare otolaryngological disorders between children with EDS and those not affected by EDS. METHODS: A retrospective chart review was conducted using the US collaborative network within TriNetX. The EDS group was defined by ICD-10 code G47.33, while the non-EDS group excluded any patients with an EDS diagnosis. Cohorts were matched by age, sex, and race using propensity score matching. Pathologies analyzed included hearing loss (ICD-10H90, H91), otitis media (ICD-10H66, H65), allergic rhinitis, acute tonsillitis (ICD-10 J03), sinusitis (ICD-10 J32, J01), and obstructive sleep apnea (OSA) (ICD-10 G47.33). Chi-square and relative risk within a 95 % confidence interval were calculated. RESULTS: Propensity score matching yielded 6440 patients (male: N = 2,523, 39.2 %; female: N = 3,893, 60.5 %; unknown: N = 24, 0.37 %) with a mean age of 9.28 years (SD = 4.38). Children with EDS were 2.04 times more likely to be diagnosed with hearing loss, occurring in 286 (4.4 %) EDS children versus 140 (2.1 %) controls (P < 0.001). Children with EDS were 1.6 times more likely to be diagnosed with allergic rhinitis, occurring in 436 (6.8 %) EDS children versus 274 (4.2 %) controls (P < 0.001). Children with EDS were also 1.52 times (EDS: N = 350, 5.4 %; control: N = 231, 3.6 %) and 4.24 times (EDS: N = 335, 5.2 %; control: N = 79, 1.2 %) more likely to develop sinusitis and be diagnosed with OSA, respectively, compared to children without EDS (P < 0.001). However, children with EDS were only 0.71 times as likely to develop acute tonsillitis, with 101 (1.6 %) of EDS children compared to 142 (2.2 %) of control children being diagnosed (P = 0.009). No statistical difference was found in risk of developing otitis media. CONCLUSIONS: Children with EDS are at higher risk of developing hearing loss, allergic rhinitis, acute sinusitis, and OSA, possibly due to underlying immune dysfunction. Pediatric otolaryngologists should be vigilant about these otolaryngologic sequela in EDS patients.

Assisted reproductive techniques and subsequent risk of asthma and allergic rhinitis in offspring: a nationwide birth cohort study in South Korea.

OBJECTIVE: The relationship between assisted reproductive techniques (ART) and the risk of asthma and allergic rhinitis (AR) is controversial. Thus, we aimed to investigate the relationship between ART and the risk of asthma and AR in a nationwide, large-scale birth cohort. PATIENTS AND METHODS: This study utilized the National Health Insurance Service data in South Korea to conduct a nationwide, large-scale, population-based birth cohort. We included all infants born between 2017 and 2018. AR, asthma, food allergies, and atopic dermatitis were defined using the International Classification of Diseases tenth edition codes. Asthma was classified as allergic or non-allergic based on accompanying allergic diseases (AR, food allergy, or atopic dermatitis). Using 1:10 propensity score matching, we compared infants conceived through ART with those conceived naturally (non-ART). After matching, logistic regression was used to compare the hazard ratio for asthma and AR between the two groups. RESULTS: We included 543,178 infants [male infants, 280,194 (51.38%)]. After matching, 8,925 and 74,229 infants were selected for the ART and non-ART groups, respectively. The ART group showed a decreased risk of asthma in the offspring [adjusted hazard ratio (aHR), 0.45; 95% confidence interval (CI), 0.41-0.48]. Similarly, for AR, being conceived by ART was associated with a decreased risk of AR (aHR, 0.25; 95% CI, 0.12-0.37). ART offspring showed a decreased risk of asthma and AR in offspring compared to that observed in non-ART offspring. CONCLUSIONS: Our study offers important insights for clinicians, researchers, and parents regarding the health outcomes of ART-conceived infants and enhances our understanding of ART's impact on respiratory health.

[Bronchial asthma and allergic rhinitis-The skin sample reveals a severe systemic disease]. / Asthma bronchiale und allergische Rhinitis ­ die Hautprobe offenbart eine schwerwiegende Systemerkrankung.

This article reports the case of a 30-year-old female patient who suffered for many years from initially unspecific symptoms, such as recurrent, nonallergic and noninfectious sinusitis, late-onset bronchial asthma and pronounced lymphadenopathy; however, the correct diagnosis of eosinophilic granulomatosis with polyangiitis (EGPA) could only be made by histological investigations after the appearance of skin symptoms. The EGPA is a severe systemic disease which, if left untreated, can cause multiple organ damage and even be fatal. With adequate treatment the disease is mild in more than 90% of cases and patients can even completely recover. By making the correct diagnosis, the patient could be successfully treated and the risk of late manifestations and subsequent damage with a potentially fatal outcome was reduced.

Comorbidities associated with adult asthma: a population-based matched cohort study in Finland.

BACKGROUND: Asthma is a common chronic disease characterised by variable respiratory symptoms and airflow limitation, affecting roughly 4%-10% of the adult population. Adult asthma is associated with higher all-cause mortality compared to individuals without asthma. In this study, we investigate the comorbidities that may affect the management of asthma. METHODS: Total of 1648 adults with asthma and 3310 individuals without asthma aged 30-93 were matched with age, gender and area of residency, and followed from 1 January 1997 to 31 December 2013. Baseline information was collected with questionnaires 1997 and follow-up register data from the national discharge registry Finnish Institute for Health and Welfare. Data included diagnoses from outpatient care and day surgery of specialised health care, and data from inpatient care of specialised and primary health care. We included all main diagnoses that had at minimum 200 events and number of diagnoses based on their common appearance with adult asthma. RESULTS: The mean follow-up time varied between 14.2 and 15.1 years, and age at the time of enrolment was 53.9 years for subjects without asthma and 54.4 years for patients with asthma. Chronic obstructive pulmonary disease was 10 times more common among asthmatics. Risk of acute rhinosinusitis, chronic rhinosinusitis with nasal polyps, atopic dermatitis and vocal cord dysfunction was fourfold and risk of pneumonia, and chronic rhinosinusitis was 2.5 times more common among asthmatics. Sleep apnoea, gastro-oesophageal reflux disease, diabetes, allergic rhinitis and dysfunctional breathing were twofold and cataract nearly twofold higher in the asthmatic group. Adult asthma was also significantly associated with musculoskeletal diseases, incontinence and bronchiectasis. CONCLUSIONS: The most common and most severe comorbidity of adult asthma in this study was chronic obstructive pulmonary disease. Other common comorbidities of adult asthma include acute rhinosinusitis, chronic rhinosinusitis with nasal polyps, atopic dermatitis, allergic rhinitis, dysfunctional breathing, diabetes, pneumonia, sleep apnoea and gastro-oesophageal reflux disease.

Investigating the epidemiological relevance of secretory otitis media and neighboring organ diseases through an Internet search.

Background: This study examined the epidemiological correlations between secretory otitis media (SOM) and diseases of neighboring organs. We measured changes in disease incidences during the 2020 COVID-19 pandemic using Internet big data spanning from 2011 to 2021. Methods: This study used the Baidu Index (BI) to determine the search volume for the terms "secretory otitis media (SOM)", "tonsillitis", "pharyngolaryngitis", "adenoid hypertrophy (AH)", "nasopharyngeal carcinoma (NPC)", "nasal septum deviation (NSD)", "rhinosinusitis", "allergic rhinitis (AR)", and "gastroesophageal reflux disease (GERD)" in Mandarin from January 2011 to December 2021. The correlations between these terms were analyzed using Spearman's correlation coefficients. The results were compared search data from 2019 and 2021 to assess the effects of isolation on SOM in 2020. Results: The seasonal variations trends of SOM and other diseases coincided well (P < 0.05), except for AR. During the 11-year timeframe, the monthly searches for rhinosinusitis, NSD, tonsillitis, pharyngolaryngitis, and NPC were statistically correlated with SOM (R = 0.825, 0.594, 0.650, 0.636, 0.664, respectively; P < 0.05). No correlation was found between SOM and AR, SOM and AH, or SOM and GERD (R =  - 0.028, R = 0.259, R = 0.014, respectively, P > 0.05). The total search volumes for SOM, rhinosinusitis, NPC, and AH decreased in 2020 compared to 2019. Discussion: SOM exhibited a discernible epidemiological connection with rhinosinusitis, nasal septal deviation (NSD), tonsillitis, pharyngolaryngitis, and nasopharyngeal carcinoma (NPC). A decrease in public gatherings was observed to effectively reduce the incidences of SOM. This underscores the pivotal role of social measures in influencing the prevalence of SOM and emphasizes the intricate interplay between SOM and various associated health factors, with implications for public health strategies.

Allergic Rhinitis: A Review.

Importance: Allergic rhinitis affects an estimated 15% of the US population (approximately 50 million individuals) and is associated with the presence of asthma, eczema, chronic or recurrent sinusitis, cough, and both tension and migraine headaches. Observations: Allergic rhinitis occurs when disruption of the epithelial barrier allows allergens to penetrate the mucosal epithelium of nasal passages, inducing a T-helper type 2 inflammatory response and production of allergen-specific IgE. Allergic rhinitis typically presents with symptoms of nasal congestion, rhinorrhea, postnasal drainage, sneezing, and itching of the eyes, nose, and throat. In an international study, the most common symptoms of allergic rhinitis were rhinorrhea (90.38%) and nasal congestion (94.23%). Patients with nonallergic rhinitis present primarily with nasal congestion and postnasal drainage frequently associated with sinus pressure, ear plugging, muffled sounds and pain, and eustachian tube dysfunction that is less responsive to nasal corticosteroids. Patients with seasonal allergic rhinitis typically have physical examination findings of edematous and pale turbinates. Patients with perennial allergic rhinitis typically have erythematous and inflamed turbinates with serous secretions that appear similar to other forms of chronic rhinitis at physical examination. Patients with nonallergic rhinitis have negative test results for specific IgE aeroallergens. Intermittent allergic rhinitis is defined as symptoms occurring less than 4 consecutive days/week or less than 4 consecutive weeks/year. Persistent allergic rhinitis is defined as symptoms occurring more often than 4 consecutive days/week and for more than 4 consecutive weeks/year. Patients with allergic rhinitis should avoid inciting allergens. In addition, first-line treatment for mild intermittent or mild persistent allergic rhinitis may include a second-generation H1 antihistamine (eg, cetirizine, fexofenadine, desloratadine, loratadine) or an intranasal antihistamine (eg, azelastine, olopatadine), whereas patients with persistent moderate to severe allergic rhinitis should be treated initially with an intranasal corticosteroid (eg, fluticasone, triamcinolone, budesonide, mometasone) either alone or in combination with an intranasal antihistamine. In contrast, first-line therapy for patients with nonallergic rhinitis consists of an intranasal antihistamine as monotherapy or in combination with an intranasal corticosteroid. Conclusions and Relevance: Allergic rhinitis is associated with symptoms of nasal congestion, sneezing, and itching of the eyes, nose, and throat. Patients with allergic rhinitis should be instructed to avoid inciting allergens. Therapies include second-generation H1 antihistamines (eg, cetirizine, fexofenadine, desloratadine, loratadine), intranasal antihistamines (eg, azelastine, olopatadine), and intranasal corticosteroids (eg, fluticasone, triamcinolone, budesonide, mometasone) and should be selected based on the severity and frequency of symptoms and patient preference.

Evaluation of the treatment strategy for complicated allergic rhinitis.

OBJECTIVE: Aim: To carry out a comprehensive evaluation of treatment modification for patients with seasonal allergic rhinitis (SAR) complicated by anxiety-neurotic disorders. PATIENTS AND METHODS: Materials and Methods: Patients with SAR in the acute stage on the background of anxiety disorders were studied. Immunological studies were carried out, an assessment of the dynamics of indicators of the quality of life of patients, the level of anxiety / depression was assessed. In the clinical group, a variant of therapy modification was proposed. RESULTS: Results: Significant changes in the subpopulation ratio of lymphocytes, an increase in the immunoregulatory index, which indicated the severity of the immunological process, were revealed in SAR patients in the acute stage against the background of anxiety disorders. At the same time, a significant activation of the humoral link of immunity was observed: an increase and a significant increase in IgE in the blood serum and an increase in the content of sIgA in the nasal secretion. In most patients, eosinophilia was found in the peripheral blood and in the rhinocytogram before treatment. In the study of the quality of life of patients, changes in many parameters were found. CONCLUSION: Conclusions: The combination of "Nazafort Allergy Protection" and Atarax seems to be the most successful, which significantly improved the physical and psycho-emotional state of patients with SAR, complicated by anxiety and neurotic disorders. This combination led to an increase in the stress resistance of patients.

Epidemiological characterization and risk factors of rhinitis and rhinoconjunctivitis among preschool children in Shanghai, China.

BACKGROUND: Previous studies have reported an increasing prevalence of childhood allergic rhinitis in developing countries. There is still a lack of the recent epidemiology of allergic rhinitis among Chinese preschool children. Therefore, this study explored the prevalence of rhinitis symptoms and identified their associations with potential risk factors among children at the age of 3-6 in Shanghai, China. METHODS: Validated International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire was adopted to collect information about rhinitis symptoms and potential risk factors. Univariate and multivariate logistic regression analyses were used to assess associations between risk factors and allergic rhinitis and rhinoconjunctivitis. RESULTS: A total of 6183 questionnaires were included in our study. The prevalence of rhinitis ever, current rhinitis, and physician-diagnosed rhinitis were 32.6%, 29.2%, and 14.3%, respectively, while the prevalence of current rhinoconjunctivitis was 11.3%. The higher prevalence was observed in boys than in girls in terms of rhinitis ever, current rhinitis, current rhinoconjunctivitis and doctor-diagnosed rhinitis. Autumn had the highest prevalence among four seasons. In our multivariate logistic regression analyses, history of allergic diseases and paracetamol use in the last year showed positive associations with the increased risk of both current rhinitis and rhinoconjunctivitis, and antibiotic use was an independent significant risk factor only for current rhinitis. Genetic factors, including maternal and paternal rhinitis, asthma, and eczema, were significantly associated with the prevalence of current rhinitis. Similar associations were seen between these factors and current rhinoconjunctivitis, except for paternal eczema. Among environmental factors, smoking exposure at home, heavy truck traffic in home's street, floor heating system were independent risk factors for both current rhinitis and rhinoconjunctivitis in the adjusted model, while cleaning the house less than once a week was only associated with current rhinitis. CONCLUSION: The prevalence of current rhinitis was 29.2% among children aged 3-6 in Shanghai, China. Sex differences and seasonal variations were observed in the prevalence of rhinitis symptoms. The identified risk factors would provide a basis for policy makers and medical experts to take intervention measures to prevent allergic rhinitis and rhinoconjunctivitis.

When It's Not Allergic Rhinitis: Clinical Signs to Raise a Patient's Suspicion for Chronic Rhinosinusitis.

OBJECTIVE: To identify predictors of chronic rhinosinusitis (CRS) in patients presenting with the chief complaint of nasal allergies. STUDY DESIGN: Cross-sectional study. SETTING: Tertiary care, academic center. METHODS: Clinical and demographic characteristics were collected from participants who were patients presenting with the chief complaint of nasal allergies. From all participants, a 22-item Sinonasal Outcome Test (SNOT-22) was collected, and a modified Lund-Kennedy endoscopy score was calculated from nasal endoscopy. Association was sought between having CRS and variables of clinical and demographic characteristics, SNOT-22, and endoscopy score. RESULTS: A total of 219 patients were recruited and 91.3% were diagnosed with allergic rhinitis; 45.2% were also diagnosed with CRS. Approximately half of the patients with CRS reported no intranasal corticosteroid usage. Having CRS was associated with male sex (odds ratio [OR] = 2.29, 95% confidence interval [CI]: 1.30-4.04, P = .004), endoscopy score (OR = 1.96, 95% CI: 1.59-2.42, P < .001), and the SNOT-22 nasal subdomain score (OR = 1.07, 95% CI: 1.03-1.11, P = .001) related to SNOT-22 items: "need to blow nose," "thick nasal discharge," "sense of taste/smell," and "blockage/congestion of nose." At least moderate (item score ≥3) "blockage/congestion of nose" or "thick nasal discharge," mild "need to blow nose" (item score ≥2) or very mild decreased "sense of taste/smell" (item score ≥1), and any nasal endoscopy findings (endoscopy score ≥1) were statistically significant predictors of CRS. CONCLUSION: Moderate or more severe nasal obstruction or discharge symptoms, any decreased sense of smell/taste, or positive nasal endoscopy findings in patients believing they have allergic rhinitis should prompt further evaluation of CRS to avoid delays in treatment.

Association of allergic rhinitis with persistent obstructive sleep apnea: A secondary analysis of the childhood adenotonsillectomy trial.

STUDY OBJECTIVES: Allergic rhinitis (AR) is frequently reported in children suffering from obstructive sleep apnea (OSA). This study aimed to assess whether children with AR are more likely to experience persistent OSA after AT. METHODS: This study is a secondary analysis of a multi-center randomized clinical trial, the Childhood Adenotonsillectomy Trial. Children were categorized into the AR group or Non-AR group according to AR response. A subgroup analysis was conducted using a logistic regression model. RESULTS: A total of 372 children (177 boys [47.6%]; median [IQR] age, 6.0 [5.0-8.0] years) were analyzed. Approximately 25% (93/372) of children presented with AR. Baseline data indicated higher PSQ scores and OSA-18 scores in the AR group. Children with AR demonstrated lower OSA resolution rates after AT (aOR, 0.43; 95% CI, 0.19 to 0.96). However, there was no significant difference in OSA resolution between the AR and Non-AR groups who underwent watchful waiting (aOR, 0.98; 95% CI, 0.50 to 1.93). Also, the AR group was more likely to maintain a PSQ score greater than 0.33 after AT (OR, 2.16; 95% CI, 1.01 to 4.61). There was no significant association between AR and higher follow-up OSA-18 scores after AT and watchful waiting. CONCLUSIONS: In this secondary analysis, children with AR were more likely to experience persistent OSA, highlighting the importance of effective AR management even post-adenotonsillectomy. A purposefully designed, prospective randomized trial is needed to verify the association between AR and persistent OSA. TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT00560859.

Tic disorder in allergic rhinitis children and adolescents: a case-control study.

BACKGROUND: Allergic rhinitis is the most common allergic disease. It can accompany psychological disorders such as tic disorders due to the prolonged course of the symptoms of allergic rhinitis. This pioneer case-control study aims to investigate tic disorders in children and adolescents under 18 years of age diagnosed with allergic rhinitis. METHOD: The case group in this study consisted of patients who had both allergic rhinitis and tic disorders. Patients with allergic rhinitis without tic disorders were also enrolled as the control group with matched gender and age. Demographic characteristics, tic classifications, and contributing factors for allergic rhinitis and tic disorders were studied among the cases. Tic disorders were evaluated using DSM-5 criteria for the classification of tic disorders. RESULTS: 47 patients in the case group and 47 patients in the control group were included in this study. 53.2% and 46.8% were males and females in the case group, respectively. The mean age of the patients was 10.46 ± 3.97 years old. Sound tics were more common among the patients compared to motor tics. Patients with concomitant AR and tic disorders had more days per week with AR symptoms (P-value ≤ 0.001; OR (every day vs. three days a week = 11.02(2.98, 40.76))). Most patients with sound tick were women (p: 0.026), and most patients with motion tic were in the Provisional tic disorder group (p: 0.001). The history of infantile eczema was seen more in patients without sound tic (p: 0.025), and otitis media was significantly less common among patients with sound tics (p: 0.026). Provisional tic disorder was the most common class among the patients. In the case group (coexistence between allergic rhinitis and tic) compared to the control group, patients had significantly more days with AR symptoms per week. CONCLUSION: This preliminary study indicates that Provisional tic disorder was the most common classification of tic among patients with allergic rhinitis, especially in patients with motor tics. Asthma in motor tics, a history of food allergy in infancy, and a history of infantile eczema were also common among patients with vocal tics. Also, patients with allergic rhinitis and tic had more severe disease (more symptoms per week) than those with rhinitis alone. These findings emphasize the association of tic disorders with immunological pathways.

Sleep and allergic diseases among young Chinese adults from the Singapore/Malaysia Cross-Sectional Genetic Epidemiology Study (SMCGES) cohort.

BACKGROUND AND OBJECTIVE: Sleep disruption has been shown to affect immune function and thus influence allergic disease manifestation. The specific effects of sleep on allergic diseases, however, are less well-established; hence, in a unique population of young Chinese adults, we investigated the association between sleep and allergic disease. METHODS: Young Chinese adults recruited from Singapore in the Singapore/Malaysia Cross-Sectional Genetic Epidemiology Study (SMCGES) were analyzed. We used the International Study of Asthma and Allergies in Childhood (ISAAC) protocol and a skin prick test to determine atopic dermatitis (AD), allergic rhinitis (AR), and asthma status. Information regarding total sleep time (TST) and sleep quality (SQ) was also obtained. RESULTS: Of 1558 participants with a mean age of 25.0 years (SD = 7.6), 61.4% were female, and the mean total sleep time (TST) was 6.8 h (SD = 1.1). The proportions of AD, AR, and asthma were 24.5% (393/1542), 36.4% (987/1551), and 14.7% (227/1547), respectively. 59.8% (235/393) of AD cases suffered from AD-related sleep disturbances, 37.1% (209/564) of AR cases suffered from AR-related sleep disturbances, and 25.1% (57/227) of asthma cases suffered from asthma-related sleep disturbances. Only asthma cases showed a significantly lower mean TST than those without asthma (p = 0.015). Longer TST was significantly associated with lower odds of AR (OR = 0.905, 95% CI = 0.820-0.999) and asthma (OR = 0.852, 95% CI = 0.746-0.972). Linear regression analyses showed that lower TST was significantly associated with asthma (ß = - 0.18, SE = 0.076, p-value = 0.017), and AR when adjusted for AR-related sleep disturbances (ß = - 0.157, SE = 0.065, p-value = 0.016). Only sleep disturbances due to AR were significantly associated with a poorer SQ (OR = 1.962, 95% CI = 1.245-3.089). CONCLUSIONS: We found that sleep quality, but not sleep duration was significantly poorer among AD cases, although the exact direction of influence could not be determined. In consideration of the literature coupled with our findings, we posit that TST influences allergic rhinitis rather than vice versa. Finally, the association between TST and asthma is likely mediated by asthma-related sleep disturbances, since mean TST was significantly lower among those with nighttime asthma symptoms. Future studies could consider using objective sleep measurements coupled with differential expression analysis to investigate the pathophysiology of sleep and allergic diseases.

Association between hidradenitis suppurativa and atopic diseases: a multi-center, propensity-score-matched cohort study.

Background: Cross-sectional evidence has suggested a high prevalence of atopic diseases in patients with hidradenitis suppurativa (HS). However, there is a lack of evidence based on longitudinal studies. This study aimed to assess the risk of different atopic diseases, including asthma, atopic dermatitis, and allergic rhinitis, in patients with HS. Methods: In this retrospective cohort study, data from the TriNetX research network were obtained. Patients with HS were enrolled, and a 1:1 propensity score matching was performed to select a non-HS control group. Matching covariates included age, sex, race, comorbidities, comedications, socioeconomic status, lab data, and medical utilization status. Hazard ratios (HR) for atopic diseases were assessed. Results: Over a 15-year follow-up period, patients with HS were found to be at a higher risk for atopic dermatitis (HR = 1.65; 95% CI, 1.44-1.90), asthma (HR = 1.41; 95% CI, 1.33-1.49), and allergic rhinitis (HR = 1.08; 95% CI, 1.03-1.13). A similar trend was observed in shorter follow-up periods. The association between HS, atopic dermatitis, and asthma was consistent across different age and sex subgroups. Conclusion: Atopic diseases including atopic dermatitis, asthma and allergic rhinitis are associated with HS. Further investigation is needed to assess the necessity of early screening for atopic diseases in patients with HS.
