  Purpose
The purpose of this study is to determine the best duration(3 versus 6 weeks) of antibiotics as part of maximal medical therapy for treating chronic sinusitis and thus preventing patients from having to have sinus surgery. The hypothesis is that in the context of maximal medical therapy 3 weeks of antibiotics is not worse than 6 weeks of antibiotics at successfully treating chronic sinusitis.

Primary Outcome Measures:
  • Number of Patients Recommended for Sinus Surgery After 3 Weeks of Antibiotic Therapy [ Time Frame: 4-5 weeks after starting antibiotics ]
    Recommendation for sinus surgery after completion of maximal medical therapy is determined by the subject's treating physician and is based on two citeria: (1) persistence of symptoms and (2) objective evidence of disease on post-treatment sinus CT scan or nasal endoscopy. Symptomatic improvement of sinusitis symptoms will be assessed by: patient self report, change in Chronic Sinusitis Survery (CSS) score and change in RhinoSinusitis Disibility Index (RSDI) score relative to initial pre-antibiotic CSS and RSDI survey scores.

  • Number of Patients Recommended for Sinus Surgery After 6 Weeks of Antibiotic Therapy [ Time Frame: 7-8 weeks after initiating antibiotics ]
    Recommendation for sinus surgery after completion of maximal medical therapy is determined by the subject's treating physician and is based on two citeria: (1) persistence of symptoms and (2) objective evidence of disease on post-treatment sinus CT scan or nasal endoscopy. Symptomatic improvement of sinusitis symptoms will be assessed by: patient self report, change in Chronic Sinusitis Survery (CSS) score and change in RhinoSinusitis Disibility Index (RSDI) score relative to initial pre-antibiotic CSS and RSDI survey scores.

Arms Assigned Interventions
Active Comparator: Doxycycline, 3 weeks
Subjects with chronic rhinosinusitis with nasal polyps (CRSwNP) will receive Doxycycline 100mg BID or if allergic to doxycycline, then Augmentin 875mg BID for 3 weeks duration. These patients will also receive a course of Prednisone (30mg x 3d, 20mg x 3d, 10mg x3d, 10mg every other day for 6 days (3 doses)) which is standard of care treatment for patients with chronic sinusitis with nasal polyps.
Drug: Doxycycline
Subjects with CRSwNP who are not allergic to doxycycline will receive Doxycycline 100mg BID for either 3 or 6 weeks duration.
Drug: Augmentin
If a subject in any of the study arms is allergic to the medication he/she is supposed to receive, he/she will be given Augmentin 875mg BID for either 3 or 6 weeks duration
Active Comparator: Doxycycline, 6 weeks
Subjects with Chronic Rhinosinusitis with Nasal Polyps (CRSwNP)will receive Doxycycline 100mg BID or if allergic to doxycycline, then Augmentin 875mg BID for 6 weeks duration. These patients will also receive a course of Prednisone (30mg x 3d, 20mg x 3d, 10mg x3d, 10mg every other day for 6 days (3 doses)) which is standard of care treatment for patients with chronic sinusitis with nasal polyps.
Drug: Doxycycline
Subjects with CRSwNP who are not allergic to doxycycline will receive Doxycycline 100mg BID for either 3 or 6 weeks duration.
Drug: Augmentin
If a subject in any of the study arms is allergic to the medication he/she is supposed to receive, he/she will be given Augmentin 875mg BID for either 3 or 6 weeks duration
Active Comparator: Azithromycin, 3 weeks
Subjects with Chronic Rhinosinusitis without Nasal Polyps will receive Azithromycin 250mg daily, or if allergic to azithromycin, then Augmentin 875mg BID for 3 weeks duration.

Subjects with CRS without Nasal Polyposis (CRSwNP)who are not allergic to azithromycin will be given Azithromycin 250mg daily for either 3 or 6 weeks duration.
Drug: Augmentin
If a subject in any of the study arms is allergic to the medication he/she is supposed to receive, he/she will be given Augmentin 875mg BID for either 3 or 6 weeks duration
Active Comparator: Azithromycin, 6 weeks
Subjects with chronic Rhinosinusitis without Nasal Polyps will receive Azithromycin 250mg daily, or if allergic to azithromycin, then Augmentin 875mg BID for 6 weeks duration.
Drug: Azithromycin
Subjects with CRS without Nasal Polyposis (CRSwNP)who are not allergic to azithromycin will be given Azithromycin 250mg daily for either 3 or 6 weeks duration.
Drug: Augmentin
If a subject in any of the study arms is allergic to the medication he/she is supposed to receive, he/she will be given Augmentin 875mg BID for either 3 or 6 weeks duration
