Efficacité comparée de la pristinamycine en quatre jours et du céfuroxime axétil en cinq jours dans le traitement des sinusites maxillaires aiguës bactériennes de l'adulte

Abstract

Objective. – The aim of this multicentric, randomized, double blind study was to demonstrate that a 4-day treatment with pristinamycin 1 g bid was as efficient as a 5-day treatment with cefuroxime axetil 250 mg bid in adults presenting with an acute maxillary sinusitis. Design. – The clinical diagnosis was based on the association of sub-orbital pain, purulent rhinorrhea and purulent discharge on the middle nasal meatus and was confirmed radiologically. A rhinoscopic bacteriologic sampling was made on the middle nasal meatus. Results. – Four hundred and eighty five patients were included in the study: in France ( n = 301), Tunisia ( n = 48), Poland ( n = 69) and Argentina ( n = 67) between January 2001 and February 2002. Cultures were positive in 199/434 patients (46%), mainly S. pneumoniae (34.2%), H. influenzae (21.5%), S. aureus (15.4%), and M. catharralis (7.9%). The clinical cure rate at day12–19 in the per protocol population, the main study criterion, was equal to 91.4% (201/220) and 91.1% (195/214) respectively in the pristinamycin and cefuroxime axetil groups; δ = 0.14%; 95%CI: [–5.1%; 5.3%]. The non-inferiority of 4-day pristinamycin versus 5-day cefuroxime axetil was demonstrated. The efficacy at follow up after treatment (day26–31) was 88.6% and 85.8% respectively, confirming the non-inferiority. The bacteriological cure rate at day12–19 was 87% (87/100) and 87.9% (87/99) respectively. Both treatments were well tolerated. Conclusion. – A 4-day course with pristinamycin 1 g bid is as effective as a 5-day course of cefuroxime axetil 250 mg bid in the treatment of acute maxillary sinusitis in adults.
