title: Efficacy of cefditoren in the treatment of upper respiratory tract infections: a pooled analysis of six clinical trials.
abstract: OBJECTIVE
  A pooled analysis of all upper respiratory tract infection studies performed with cefditoren (CDN) was performed.
  
  
  METHODS
  Studies were prospective, comparative, multicentre and randomised. Comparators were penicillin V (pharyngitis) and cefuroxime or amoxicillin/clavulanate (sinusitis). A total of 1,322 patients were randomized, 1,241 included in intention-to-treat (ITT) and 1,010 in per-protocol populations (PP) in pharyngotonsillitis studies, and 1,819 randomized, 1,726 included in ITT and 1,589 in PP in acute sinusitis studies.
  
  
  RESULTS
  No significant differences in pharyngitis clinical response were found (success rates: 89.4 % to 95.3 %). S. pyogenes eradication was higher with cefditoren at end of therapy (EOT) (90.4% vs. 82.7%; p=0.002) and follow-up (84.7% vs. 76.7%; p=0.008), although no statistically significant (p<0.001). In both groups, clinical failures were significantly higher (p<0.001) in patients showing S. pyogenes persistence than in those showing eradication (> or =98.5% vs. 51.4 %). No differences in sinusitis clinical response were found between CDN and comparators both at EOT (80.2% vs. 84.8%) and at end of follow-up (71.2% vs. 77.4%).
  
  
  CONCLUSIONS
  Cefditoren had similar point estimates of clinical efficacy to comparators in pharyngotonsillitis and sinusitis, and a tendency to higher S. pyogenes eradication in pharyngotonsillitis.
