Conditions: Sinusitis
Allocation: RANDOMIZED | Intervention model: PARALLEL
Enrollment: 24
Healthy volunteers: no

Brief summary:
Chronic rhinosinusitis is a common disease that effects millions of people world wide. Despite its frequency it is unclear what treatment options are the best for these patients. Typically patients with chronic rhinosinusitis without nasal polyps (CRSsNP) are given a long term antibiotic (3 weeks), nasal steroid sprays, saline nasal irrigation and occasionally oral steroids. Oral steroids benefit patients with chronic rhinosinusitis with nasal polyps (CRSwNP) however their role in non polyp patients is less clear. It is the goal of this study to see if oral steroids benefit the treatment outcomes in those patients with chronic rhinosinusitis without nasal polyps. In addition this study will look to see if a short course (5 day burst) versus a longer course (21 day taper) of oral steroids make a difference in outcomes.

Detailed description:
The investigators will compare patients with CRSsNP who are treated with antibiotics/nasal steroid sprays, and compare them to chronic sinusitis patients who receive antibiotics/nasal steroid spray along with a course of oral steroids. The goal is to determine if oral steroids have a role in CRSsNP, and if so, the most effective dosage.

Arms:
arm 1: 1\. Augmentin (amoxicillin/clavulanate 875/125mg) orally (PO) twice a day for 3 weeks. arm 2: Augmentin with 6 day prednisone taper (40mg PO daily (QD) for 2 days, 20mg PO QD for 2 days, 10mg PO QD for 2 days, then stop) arm 3: Augmentin with 21 days prednisone taper (40mg PO QD for 5 days, 30mg PO QD for 5 days, 20mg PO QD for 5 days, 10mg PO QD for 5 days, then stop. )

Interventions: intervention 1: 6 day Prednisone intervention 2: Augmentin intervention 3: 21 day Prednisone
Intervention descriptions: intervention 1: 6 day prednisone burst intervention 2: Antibiotic augmentin for 3 weeks intervention 3: 21 day prednisone burst

8. STUDY DESIGN 
a. Background or rationale for this study: Chronic sinus infections (chronic 
sinusitis or CRS) are common conditions that affect millions of Americans. This 
disease can be divided into two main patient groups: Patients with chronic 
rhinosinusitis without nasal polyps (CRSsNP) and those with nasal polyps 
(CRSwNP). We will be focusing on the non-polyp group. While this is a common 
disorder, medical treatments for this condition vary considerably and little is 
known how and why different treatments work in some individuals and not in 
others. Topical nasal steroids and oral antibiotics are the mainstay and 
standard of care for both CRSsNP and CRSwNP. Oral steroids are commonly 
given for both of these sinusitis variants, however their role in non-polyp CRS 
patients is less well delineated. The purpose of this research study is to better 


understand whether orally administered steroids results in superior results 
when compared with nasally sprayed steroids in this population. The 
investigators will compare patients with chronic sinusitis who are treated with 
antibiotics, topical nasal sprayed steroid therapy, and compare them to chronic 
sinusitis patients who receive antibiotics and nasally sprayed steroid therapy 
along with a short course or long course of oral steroids. The goal is to 
determine if oral steroids have a role in CRSsNP, and if so, the most effective 
dosage. 
b. Objectives. To compare the effectiveness of topical nasal steroid sprays, oral 
antibiotics and saline nasal irrigations versus topical nasal steroids, oral 
antibiotics, saline nasal irrigation + oral corticosteroids (prednisone) in CRS 
patients without nasal polyps. 
c. Procedures involved (Research Interventions). Chronological order of all 
research interventions, distinguishing standard of care vs. research 
intervention: 
4 
1. At the time of enrollment nasal endoscopy will be performed to confirm that the 
patient does not have evidence of nasal polyps. Office-based sinus CT scan will 
also be completed on initial visit. Lund-McKay score at initiation of treatment 
will be one a determinate of study eligibility. (Lund-McKay staging system is 
currently the most widely accepted system to radiographically characterize and 
diagnose CRS. A score of 6 or greater indicates significant sinus disease and 
meets inclusion criteria for study. See below table 1 for Lund-McKay staging 
system.) Note: Endoscopy and CT of paranasal sinuses are the standard of care 
for evaluation of patients with symptoms of CRS and will be offered to all patients 
presenting with these symptoms regardless of study enrollment status. 
2. Subjects will be asked to fill out a SNOT 22 survey before the start of therapy. 


(SNOT 20 form attached). 
3. Nasal endoscopy score will also be obtained during initial visit. (Nasal endoscopy 
scoring form attached). This exam is part of the standard of care. 
4. Subjects will be randomized into 3 groups via an electronic random generator 
(see below) 
1. Group 1: Treated with oral antibiotics, nasal steroid spray and saline 
rinses for 3 weeks (standard of care) 
2. Group 2: Treated with above + Prednisone 6 day tapered dosage 
(standard of care) 
3. Group 3: Group 2: Treated with above + Prednisone 20 day tapered 
dosage (standard of care) 
4. Random generator: 
5 
5. Patients will return to office at 4 weeks (following 3 weeks of oral antibiotics, 
nasal steroid spray, nasal saline irrigation + prednisone for patients in Groups 2 
and 3), At that time, patients will be asked to fill out SNOT 22 survey, nasal 
endoscopy and CT scan to assess response to treatment. (standard of care). 
6. At the 4 week follow up, patients will be asked to fill out SNOT 22 survey, and 
undergo nasal endoscopy. (standard of care). 
d. Alternative procedures, if any, that are not included in the study but might be 
advantageous to the subject - None 
e. If any deception is required for validity of this study, explain why this is 
necessary and how subject(s) will be debriefed. - None 
f. Concise review of literature that supports the rationale, objectives, and 
methodology of the proposed study. 
1. Chronic sinus infections (chronic sinusitis or CRS) are common 
conditions that affect millions of Americans. This disease can be divided 


into two main patient groups: Patients with chronic rhinosinusitis without 
nasal polyps (CRSsNP) and those with nasal polyps (CRSwNP). We will 
be focusing on the non-polyp group. While this is a common disorder, 
medical treatments for this condition vary considerably and little is known 
how and why different treatments work in some individuals and not in 
others. Topical nasal steroids and oral antibiotics are the mainstay and 
standard of care for both CRSsNP and CRSwNP. Oral steroids are 
commonly given for both of these sinusitis variants, however their role in 
non-polyp CRS patients is less well delineated. The purpose of this 
research study is to better understand whether orally administered 
steroids results in superior results when compared with nasally sprayed 
steroids in this population, and if so, at which dosage. The investigators 
will compare patients with chronic sinusitis who are treated with 
antibiotics, topical nasal sprayed steroid therapy, and compare them to 
chronic sinusitis patients who receive antibiotics and nasally sprayed 
steroid therapy along with oral steroids. The goal is to determine if oral 
steroids have a role in CRSsNP. (See below for literature review.)
