NCT01084811

Brief Summary

The investigators will conduct a descriptive, prospective, three-armed study concerning the pathophysiology of chronic rhinosinusitis. In one part of the study the investigators want to investigate the presence of biofilm in patients with chronic rhinosinusitis both with and without nasal polyps compared with a control group of subjects without chronic rhinosinusitis. The investigators will also compare quality of life in the three groups and correlate disease severity in biofilm patients versus patients where biofilm was not present. The hypothesis here is that biofilm patients suffers a more severe disease. In the other arm of the study the investigators will compare the presence of different biochemical compounds in the three study groups. The investigators specifically want to investigate matrix metalloproteases and apoptosis-inhibitors with immunohistochemistry. The investigators may also add other compounds to our test-battery if interesting candidates surface in the literature during the inclusion period. The purpose of this part of the study is to investigate candidates for the development of nasal polyposis. The investigators plan to include 100 patients suffering from chronic rhinosinusitis with nasal polyps, and 100 patients with chronic rhinosinusitis without nasal polyps and 30 control subjects.
