Microarray Analysis of Sinus Samples From Patients With and Without Chronic Rhinosinusitis
This study is ongoing, but not recruiting participants.

Sponsor: University of California, San Francisco
Information provided by (Responsible Party): Andrew Goldberg, University of California, San Francisco
ClinicalTrials.gov Identifier: NCT00683371
  Purpose

Mucosal biopsies, endoscopically-guided brush samples of mucus, and a saline lavage taken from the maxillary sinuses of ten CRS patients undergoing sinus surgery are analyzed using three microarrays in order to detect bacteria, fungi and viruses. Ten control patients with normal sinuses will have the same samples taken. The hypothesis is that bacterial, fungal, and viral communities present in the maxillary sinus of patients with CRS are significantly different from those patients with healthy sinuses, and that microorganisms identified in patients with or without CRS will differ from previously published data obtained using other techniques.

Primary Outcome Measures:
  • Microbial community profiling using the PhyloChip, MycoChip, and ViroChip will yield vast quantities of data to be reduced in dimensions for interpretation. Pathogens detected in the nasal mucus of patients with CRS will be compared to healthy controls. [ Time Frame: Immediate Preoperative period. ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • The presence or absence of a given microorganism will be compared to previously published data obtained using either traditional culture methods or other genomic methods. [ Time Frame: Immediate preoperative period ] [ Designated as safety issue: No ]

Estimated Enrollment: 20
Study Start Date: October 2007
Estimated Study Completion Date: September 2013
Estimated Primary Completion Date: September 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Active Comparator: 1
10 patients with chronic rhinosinusitis will have three specimens collected from the maxillary sinus during surgery
 Procedure: Specimen collection
10 patients with chronic rhinosinusitis will have three specimens collected from the maxillary sinus during surgery. The sinus mucosa, sinus mucus and a saline lavage will be collected. The three samples will then be analyzed with microarrays looking for bacteria, fungi, and viruses.
Placebo Comparator: 2
10 patients without sinus disease will have three specimens collected from the maxillary sinus during surgery.
 Procedure: Specimen collection
10 patients without sinus disease will have three specimens collected from the maxillary sinus during surgery. The sinus mucosa, sinus mucus and a saline lavage will be collected. The three samples will then be analyzed with microarrays looking for bacteria, fungi, and viruses.

Detailed Description:

Mucosal biopsies, endoscopically-guided brush samples of mucus, and a saline lavage taken from the maxillary sinuses of ten CRS patients undergoing sinus surgery are analyzed using three microarrays: 16S rRNA PhyloChip (to detect bacteria), MycoChip (to detect fungi) and ViroChip (to detect viruses). Ten control patients with normal sinuses, as assessed by CT scan and a sinusitis-specific survey, will have the same samples taken. The hypothesis is that bacterial, fungal, and viral communities present in the maxillary sinus of patients with CRS are significantly different from those patients with healthy sinuses, and that microorganisms identified in patients with or without CRS will differ from previously published data obtained using other techniques. Comparing diseased and control flora will provide insight into the relative contribution of each pathogen to CRS and may guide the development of future therapies.

  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   Yes
Criteria

Inclusion Criteria (CRS patients):

  • History of CRS as defined as symptoms (nasal discharge, nasal obstruction, facial pain and/or hyposmia) for >12 weeks despite therapy.
  • Impaired CRS-specific quality of life (SNOT-20 score >1.5).
  • Evidence of sinus disease on a CT scan (Lund MacKay score greater than or equal to 10).
  • Patients with positive skin or RAST testing to an inhalant allergen and/or aspirin hypersensitivity will be included. Evidence of atopy is not required but will be recorded, along with serum IgE levels, when available.

Inclusion Criteria (Control patients):

  • No history of CRS
  • SNOT-20 score <1.0
  • No evidence of sinus disease on preoperative imaging

Exclusion Criteria:

  • Control patients with any evidence of CRS, by history, survey, or imaging criteria would be excluded.
