title: Clinical and bacteriological efficacy of 5-day telithromycin in acute maxillary sinusitis: a pooled analysis.
abstract: OBJECTIVE
  To compare the efficacy and tolerability of a 5-day course of telithromycin (800 mg once daily) with a 10-day course of telithromycin or standard comparators (amoxicillin-clavulanate 500/125 mg three times daily or cefuroxime axetil 250 mg twice daily) in patients with acute maxillary sinusitis (AMS).
  
  
  METHODS
  Data from three randomised double blind studies were pooled. The studies included patients with clinical symptoms of AMS and sinus X-ray findings of total opacity, air-fluid levels or mucosal thickening.
  
  
  RESULTS
  Pooled analysis of results for 5-day telithromycin revealed overall clinical cure rates of 83.6% (383/458 patients) at post-therapy (days 17-24) and 78.9% (330/418 patients) at late post-therapy (days 31-45) in the per-protocol population. Clinical cure rates at post-therapy were equivalent to those observed with 10-day telithromycin (82.5% vs 81.7%) or comparator treatment (80.9% vs 77.4%). Moreover, clinical cure rates exceeded 80% in subgroups of patients of interest, including those with severe infection and those fulfilling more stringent criteria for bacterial AMS. A satisfactory bacteriological outcome was achieved in 87.6% of patients. The 5-day telithromycin regimen was well tolerated.
  
  
  CONCLUSIONS
  Telithromycin once daily for 5 days offers effective treatment for AMS and is comparable to 10-day courses of standard treatments.
