Abstract:
Objective To evaluate the efficacy of low-dose and long-term clarithromycin in treatment of chronic rhinosinusitis with positive bacterial biofilms.Methods Seventy-seven patients with chronic rhinosinusitis and positive bacterial biofilms underwent functional endoscopic sinusitis surgery between January 2008 and December 2009 in department of otolaryngology of Jinhua Central Hospital.Fortytwo patients were treated with clarithromycin 250 mg/d orally for at least 3 months (trial group).At the end of 3 months patients received endoscopic examination,for patients with mucosal epithelialization the clarithromycin therapy was stopped; for those with mucosal edema,granulation or polyoid formations the clarithromycin treatment was continued,but no longer than 5 months.Thirty-five patients in control group were not given clarithromycin.All patients were assessed by visual analogue scale (VAS) and nasal endoscopic examination (Lund-kennedy score) 6 months after surgery,the results were compared between two groups.Results Two patients in the trial group did not complete the protocol.VAS score and Lundkennedy score in trial group were 8.0 ± 0.8 and 3.6 ± 1.3 at 6 month after surgery respectively,while those in the control group were 7.3 ± 0.7 and 4.5 ± 1.7,and the differences were of statistical significance (t =5.311 and-3.187,P ＜ 0.01).Conclusion Low-dose and long-term oral administration of clarithromycin has positive impact on the prognosis of bacterial biofilms positive patients with chronic rhinosinusitis.
