BACKGROUND: Nasal obstruction may contribute to the development of obstructive sleep apnea (OSA). Acoustic rhinometry (AR) measures nasal patency and congestion, which are useful parameters in objectively evaluating nasal obstruction. The nasal obstruction produced by allergic rhinitis may contribute to the development of OSA and can be easily assessed with AR. OBJECTIVE: This study was undertaken to assess the degree of nasal obstruction seen in allergic patients with and without OSA. STUDY DESIGN AND SETTING: This study was a retrospective data analysis from a tertiary referral center. The AR data from 10 patients with and 40 patients without mild OSA were compared. RESULTS: The mean congestion factors at the first cross-sectional area (CSA1) on the AR graph were found to be significantly higher in the OSA group than in the non-OSA group ( P = 0.03). The classification of change in congestion factors demonstrated significant differences at CSA1, CSA2, and CSA3 and in volume (***t distributions <0.001, 0.0312, <0.001, and <0.001, respectively). The non-OSA patients noted a significant subjective improvement in nasal congestion after topical nasal decongestion, whereas the OSA patients did not ( P < 0.0001 and 0.064, respectively). CONCLUSION: Although the role of nasal obstruction in OSA is controversial, our study lends evidence to the thought that the nasal obstruction associated with allergic rhinitis is associated with the presence of mild OSA. SIGNIFICANCE: Whether allergic rhinitis is a direct cause of OSA is debatable, but we have shown that greater nasal congestion is related to the presence of OSA in a population of patients with allergic rhinitis.

Abstract Background: There is mounting evidence for a reciprocal yet bidirectional association between sleep-disordered breathing and hypertension. Obstructive sleep apnea (OSA), a common cause of systemic hypertension is an independent risk factor for hypertension-related cardiovascular morbidity and mortality. In this comparative hospital-based cross-sectional study, we sought to explore the burden of obstructive sleep apnea and its associated risk factors among hypertensive patients attending Jakaya Kikwete Cardiac Institute.Methodology: A total of 1974 individuals (i.e. 1289 hypertensive and 685 normotensives) were consecutively enrolled in this study. The Berlin questionnaire and Epworth Sleepiness Scale were utilized in the assessment of OSA and excessive daytime sleepiness (EDS) respectively. Logistic regression analyses were employed in the determination of associated factors for OSA. Results: The mean age was 53.4 years and females constituted the large majority (60.4%) of participants. About three quarters (74.1%) of participants had excess body weight, 11.6% had diabetes, 8.0% had asthma and 18.6% had history of recurrent nasal congestion. Positive family history of snoring was reported by 43.1% of participants and 36.9% had a personal history of snoring. Persons with hypertension displayed a higher frequency (42.1%) of OSA compared to their normotensive counterparts (11.8%), p<0.001. Multivariate logistic regression analyses revealed hypertension (OR 5.1, 95% CI 3.2-8.2, p<0.001), diabetes mellitus (OR 2.2, 95% CI 1.3-3.5, p<0.01), chronic nasal congestion (OR 1.6, 95% CI 1.1-2.5, p = 0.01), obesity (OR 2.4, 95% CI 1.8-3.3, p<0.001), increased neck circumference (OR 2.7, 95% CI 1.2-6.4, p = 0.02), family history of snoring (OR 5.5, 95% CI 4.0-7.5, p<0.001), and working >8hrs/24hr (OR 0.6, 95% CI 0.4-1.0, p = 0.03) to have an independent association for OSA. Furthermore, participants with hypertension displayed superior odds for OSA compared to their normotensive counterparts across all subgroup analyses. Conclusion: OSA is considerably common among hypertensives in a tertiary health care setting in Tanzania. Positive family history of snoring was the strongest associated factor; however, excess body weight proved to be the strongest modifiable risk factor. In view of its pervasiveness, OSA should be an integral part of the medical evaluation in hypertensive individuals.

Objective: To estimate the prevalence of symptoms of obstructive sleep apnea (OSA), nasal obstruction, and enuresis in children with nonsyndromic unilateral cleft lip and palate. Design: Prospective cross-sectional study. Setting: Referral care center. Participants: One hundred seventy-four children aged 6 to 12 years of both genders. Interventions: Symptoms of OSA and nasal obstruction were investigated by analysis of scores obtained by the Sleep Disturbance Scale for Children (SDSC) and Congestion Quantifier (CQ-5). Enuresis was considered as present when urinary loss was reported during sleep (at least 1 episode/month, last 3 months). To characterize the enuresis as mono- or polysymptomatic, symptoms of dysfunction of the lower urinary tract (DLUT) were investigated by the Dysfunctional Voiding Scoring System (DVSS). Statistical analysis was performed at a 5% level of significance. Results: Positive SDSC scores for OSA were observed in 60 (34%) children; positive CQ-5 scores for nasal obstruction in 45 (26%), positive DVSS scores for DLUT in 30 (17%), and enuresis was reported by 29 (17%), being categorized as primary in 66% and polysymptomatic in 72% of the children. Compared to the pediatric population, OSA, nasal obstruction, and enuresis prevalence ratios were up to 7 (95% confidence interval [CI] 5-9), 2 (95% CI 2-3), and 3 times (95% CI 2-5) higher, respectively. There was a positive/moderate correlation between symptoms of OSA and nasal obstruction ( P = .0001). No correlation was seen between symptoms of OSA and enuresis. Conclusions: Children with nonsyndromic cleft lip and palate have high prevalence of nasal obstruction and enuresis and are at risk of OSA.

Nasal airway obstruction may exacerbate sleep apnea and is difficult to quantify on clinical examination. In this study, we examined the relationship among nasal patency, the frequency of sleep apnea events, and effective nasal continuous positive air pressures. Acoustic rhinometry was used as an objective measurement of nasal cross-sectional areas in 76 patients without nasal symptoms who underwent study with diagnostic polysomnography because of obstructive sleep apnea. Patients with persistent obstructive sleep apnea were titrated to nasal continuous positive air pressure in a split night study. All subjects had a mean apnea/hypopnea index of 28, and those with obstructive sleep apnea had a mean apnea/hypopnea index of 43. Mean cross-sectional areas 1 to 4 cm into the nose were 1.7, 1.1, 2.1, and 2.8 cm 2 , respectively (F = 39, p < 0.001). However, there was no correlation between the apnea/hypopnea index and the cross-sectional area at the four distances (r = 0.03, 0.06, 0.02, and 0.02, respectively, p = not significant). Correlations between nasal continuous positive air pressures and cross-sectional areas did not reveal a significant relationship at any of the four sites (r = 0.09, 0.07, −0.03, 0.00, respectively). Findings in patients with apnea were also compared with those in patients without apnea and significant differences were not found (F = 0.019, p = not significant). Although it would seem intuitive that increased nasal obstruction is associated with the severity of obstructive sleep apnea and difficulty with the use of nasal continuous positive air pressure, this study shows that nasal patency, as measured by acoustic rhinometry, does not correlate with the severity of obstructive sleep apnea, as determined by the apnea/hypopnea index or the effective nasal continuous positive air pressure.
