Using response to a standardized treatment to identify phenotypes for genetic studies of chronic rhinosinusitis.

Abstract

Patients with refractory chronic rhinosinusitis represent a severely diseased, more homogeneous population in which the genetic contribution(s) to disease may be maximal. Strong associations with asthma, aspirin intolerance, and atopy suggest links between these disorders. Irrigation with budesonide solution appears to be effective in management. Studies of the genetics of chronic rhinosinusitis will include genes known to be involved with both asthma and innate immunity.
