Rhinitis and onset of asthma: a longitudinal population-based study

Asthma-related comorbidities

“…Allergic rhinitic subjects have an increased risk of developing asthma [11][12][13]. A majority of asthmatic patients are affected by allergic rhinitis, which is often undiagnosed and untreated.…”

“…However, atopy does not fully explain the strong association between rhinitis and asthma. Indeed, rhinitis is also common in nonallergic asthma [13]. Nasal symptoms are associated with more severe asthma in nonatopic patients [18].…”

The International Primary Care Respiratory Group (IPCRG) Research Needs Statement 2010

“…85,101 In atopic children, the presence of allergic rhinitis is a risk factor for asthma, with a time interval of about a year before the development of asthma symptoms, 102 offering a potential window of opportunity when early detection and appropriate management of rhinitis may prevent the progression to asthma. Co-morbid rhinitis is associated with increased asthma symptoms, increased exacerbations and hospital admissions, [103][104][105] with some evidence that concomitant treatment can improve control.…”

GARD, a new way to battle with chronic respiratory diseases, from disease oriented programmes to global partnership

“…Since asthma in more than 50% adults and at least in 80% of affected children is allergic (6) and allergic rhinitis was considered as a risk factor for asthma along with other known risk factors (7,8) it was decided to integrate allergic rhinitis into current WHO initiatives. WHO Meeting on Allergic Rhinitis and its Impact on Asthma was convened in Geneva in 1999 (9).…”
