Summary

Assess if the use of SYNRINSE can improve short-term subjective and objective outcome measures after one week in patients with active Chronic Rhinosinusitis (CRS) who have had prior sinus surgery.

Detailed description

SYNRINSE is osmotically balanced and also contains soluble chitosan-argininamide, a modified natural glycopolymer that has a number of properties important to relieving the symptoms of mucus build up and bacterial biofilms. First, SYNRINSE reduces the viscosity of biofilms, the protective environment of infective bacteria that prevents topical antibiotics and other rinses to penetrate to reach the bacterial. By disrupting biofilms, SYNRINSE allows them to be cleared from the sinuses. Second, SYNRINSE has been shown to interact with the polymers comprise mucus, loosening thick, sticky layers and reducing their ability to adhere together and to mucosal surfaces. Third, all of the components in SYNRINSE are biocompatible and soothing to sensitive nasal cavities.

Conditions

• Sinusitis, Chronic
• Cystic Fibrosis With Other Manifestations

Interventions

Type	Name	Description
DRUG	Synrinse	Non-CF Cohort The first 10 non-CF subjects will be instructed to once daily irrigate both nasal passages with SynRinse (supplied) delivered via nasal irrigation using the NeilMed® Sinus Rinse™ system for 1 week. The subjects will be asked to refrain from performing any sinus irrigations during the test treatment period with any product including saline. The second set of 10 non-CF subjects (if the study continues to this point) will be instructed to irrigate both nasal passages twice daily (rather than once daily) for one week with SynRinse (supplied). The subjects will be asked to refrain from performing any sinus irrigations during the test treatment period with any product including saline. CF Cohort The first 5 subjects in the CF cohort will irrigate with with SynRinse delivered via nasal irrigation using the NeilMed Sinus Rinse system for 1 week. The second set of 5 subjects with CF will irrigate both nasal passages twice daily for one week with SynRinse.
