These data show that AR is common in the Middle East region as elsewhere in the world. Many patients with AR in Middle East region suffer from their symptoms (e.g., runny nose, nasal itching, nasal congestion, postnasal drip, and other symptoms) on all or most days during the times of the year that their allergies are worst. These symptoms have been shown to reduce QOL and performance at work/school to a significant degree. Additionally, the survey data underscore a considerable treatment gap with current therapies for AR and that many AR patients still have not found adequate effectiveness with currently available medications. Thus, through identification of disease impact on the Middle East population and highlighting treatment gaps, clinicians in the Middle East may better understand and treat AR, leading to improvements in overall patient satisfaction and QOL.

This in vitro assessment method is capable of detecting biofilm-forming capacity in bacteria recovered from individuals with CRS. This simple assay may be a useful complement to existing techniques for clinical research.
