title: Short-course, low-dose oral betamethasone as an adjunct in the treatment of acute infective sinusitis : a comparative study with placebo.
abstract: OBJECTIVE
  To assess the effect of a short course of low-dose oral corticosteroid used as an adjunct to antimicrobials in patients with acute infective sinusitis.
  
  
  METHODS
  Double-blind, randomised, placebo-controlled study including 42 patients with a clinical diagnosis of acute infective sinusitis. The study was performed at three primary healthcare sites in South Africa during the period January-November 2003.
  
  
  METHODS
  Two equal groups received either betamethasone 1mg orally (n = 21; the treatment group) or placebo tablets (n = 21; the placebo group) once a day in the morning for five consecutive days. All patients received amoxicillin-clavulanic acid 625mg orally, three times daily for 5 days.
  
  
  METHODS
  Patients rated symptoms on a daily symptom score card for 5 days and were examined by the investigator at diagnosis (day 0) and on the second visit (day 6).
  
  
  RESULTS
  Headache, facial pain, nasal congestion and dizziness improved significantly from baseline in the treatment group compared with the placebo group over 5 days of treatment (p = 0.028, p </= 0.047, p </= 0.04 and p </= 0.051, respectively). Percussion tenderness improved significantly (p = 0.049) and clearance of purulent secretions almost reached significance (p = 0.058) in the treatment group compared with the placebo group.
  
  
  CONCLUSIONS
  This study suggests a benefit of oral corticosteroid added to antimicrobial treatment of acute sinusitis and documents the first successful use of a short course of low-dose oral corticosteroid in patients with acute infective sinusitis.
