asthma sleep apnea

cross-sectional and longitudinal studies in individuals with asthma have described the occurrence of osa based on self-reported snoring, questionnaires, and sleep studies (table 1). the relationship between sex and expression of osa in individuals with asthma is not clear. the prevalence of rhinitis (allergic and nonallergic) in asthma is as high as 80–90%, and rhinitis is a risk factor for developing asthma (21, 22). ger was found to be independently predictive of habitual snoring and high osa risk in a cohort of patients with asthma (27). asthma commences early in life, traditionally as an eosinophilic airway disease, and has been shown to lead to incident osa, with a new set of symptoms overlapping those of asthma. derangements in gas exchange occur during episodes of lower-airways obstruction, and depending on the severity of obstruction, could manifest as concurrent hypoxia with or without hypercarbia.




the observation of a dose-dependent relationship between asthma duration and incident osa in humans (17) lends itself to the hypothesis that the effects of asthma on breathing control mechanisms start early in life, possibly in utero. moreover, in patients hospitalized for asthma exacerbations, osa diagnosis was related to poorer outcomes, such as the need for invasive respiratory therapy, increased lengths of stay, and costs (65). obesity is related to both asthma incidence and severity (34), and a meta-analysis found the incidence of asthma to be two times higher in overweight/obese individuals compared with healthy control subjects (33). osa may be a contributor to th1 pathways in asthma, and to the heterogeneity of the disease. at present, the recognition of sleep-disordered breathing and osa offers investigators a unique opportunity. the field of osa in asthma is in its infancy. the content of this article is solely the responsibility of the authors and does not represent the views of the department of veterans affairs, the nih, or the united states government.

studies investigating the mechanisms underlying this association and the value of periodic osa evaluation in patients with asthma are warranted. no studies, to our knowledge, have evaluated the prospective relationship of asthma with incident polysomnographically evaluated osa. as with the analyses of 4-year osa risk, participants were required to be osa-free for 2 consecutive baseline sleep studies to be eligible for 8-year osa incidence analyses.

as with the analysis of 4-year osa incidence, 5-year increments in continuous asthma duration (model 2) and longer duration asthma category (>10 years) (model 3) were associated with a higher risk of incident osa and osa with habitual sleepiness (table 5). this study prospectively examined the relationship of asthma with osa assessed with laboratory-based polysomnography and found that preexistent asthma was a risk factor for the development of clinically relevant osa in adulthood over a 4-year period. incident asthma was a strong predictor for development of habitual snoring (rr, 2.8), independent of baseline bmi and bmi change during the interval, whereas preexistent asthma was not. studies investigating the mechanisms underlying this association and the value of periodic osa evaluation in patients with asthma are warranted.

[6,7] epidemiological studies demonstrate that asthma patients more frequently report snoring, excessive daytime sleepiness, and apnea. a recent population- obstructive sleep apnea (osa) and asthma are closely related. this could be due to mere coexistence, shared risk factors, or distinct asthma and obstructive sleep apnea (osa) are long-term respiratory disorders that affect breathing. asthma causes inflammation and narrowing, sleep apnea and asthma treatment, sleep apnea and asthma treatment, asthma sleep problems, sleep apnea and asthma symptoms, can asthma cause central sleep apnea.

osa risk relates to poor overall asthma control during daytime and nighttime. additionally, osa treatment leads to improved asthma symptoms, over the full study period, the team concluded that asthma patients faced an almost 40 percent greater risk for sleep apnea than asthma-free there are several treatment options for sleep apnea. the most common, and gold-standard, therapy is a continuous positive airway pressure (cpap), can asthma cause sleep apnea va disability, sleep apnea treatment.
