Short (5 Days) Versus Long (14 Days) Duration of Antimicrobial Therapy for Acute Bacterial Sinusitis in Children
A study testing Amoxicillin-Potassium Clavulanate Combination in people with Sinusitis, run by University of Wisconsin, Madison at 2 sites in United States.
Trial summary
The investigators objective is to compare short course (5 days) to long course (14 days)antibiotics for the treatment of acute bacterial sinusitis in children. The investigators hypothesize that short course therapy will lead to more frequent relapses of sinusitis and will not reduce resistant organisms. Read more about this study

About this study

The investigators hypothesize that short course therapy will lead to more frequent relapses of sinusitis and will not reduce resistant organisms.
Read the detailed description
This was a prospective, randomized, double-blind study comparing short course (5 days) to long course (14 days) antimicrobial therapy for children between 1 and 10 years of age with acute bacterial sinusitis. The major outcome measure is the proportion of children with a clinical relapse on day 10 in the short course therapy group compared to day 20 in the long course therapy group. In addition, the proportion of respiratory flora that are resistant to antibiotics on day 30 will be compared to baseline in each group.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Amoxicillin-Potassium Clavulanate CombinationDrug
Also called there are none
All subjects will be started on treatment with 5 days of high dose amoxicillin (90mg/kg) with potassium clavulanate (6.4 mg/kg) twice daily in bottle A. The allocation to group B1 or B2 will be concealed until after the family and subject has signed the assent and consent, respectively. The maximum dose will be 2 gms twice daily. After 5 days the subjects will be randomized to either continue to receive the same dose of amoxicillin clavulanate or a look-a-like and taste-a-like placebo for the next 9 days.

| Study group | Role | What they receive |
|---|---|---|
| Short Course | Placebo comparator | Short course (5 days) of antimicrobial therapy Amoxicillin-Potassium Clavulanate Combination and placebo for next 9 days. Receives: Drug: Amoxicillin-Potassium Clavulanate Combination; Drug: Placebo |
| Long Course | Active comparator | Long course (14 days) of antimicrobial therapy Amoxicillin-Potassium Clavulanate Combination given orally for 14 days. Receives: Drug: Amoxicillin-Potassium Clavulanate Combination |
What is being measured
The primary outcome is the main question the study is designed to answer.
Proportion of Children With Clinical Relapse on Day 10 (Short Course) vs Day 20 (Long Course)
Results are based on a daily 6-item symptom survey (day 1 to 14); a daily 3-item survey (day 15 to 30). If a particular symptom is present initially, a score of 2 is given; if it is absent the score is 0. A maximum entry score is 20 (persistent symptoms). If a particular symptom becomes more severe, less severe, or stays the same during treatment, +1, -1, or 0 respectively, will be added to the original score for each symptom. At 10 (and 20 days, respectively), children will be classified as cured, improved or failed based on survey results. Children will be considered cured if they reach a score of < 2. Children will be classified as improved if their score at 10 days (20 days, respectively) is at least 2 points less than their score at 5 days (15 days, respectively). Children will be considered to have failed therapy if their score worsens by + 3 between day 5 (day 15) and day 10 (day 20) or if their score at day 10 (day 20) does not meet criteria for improvement.
