Objective:
Trimethoprim/sulfamethoxazole has been suggested as a treatment option for chronic rhinosinusitis with purulence. This study aimed to assess the functional and endoscopic outcomes after a three-month course of low-dose trimethoprim/sulfamethoxazole.
Methods:
A prospective study was performed, comprising patients referred to a tertiary care medical centre with a diagnosis of chronic rhinosinusitis with purulence. Trimethoprim/sulfamethoxazole was prescribed at 960 mg/day for three months. Sinonasal complaints and endoscopic findings were documented, and bacteriological data were compared.
Results:
Fifteen patients were included. Staphylococcus aureus was the most common bacterium cultured (86 per cent). Improvement in nasal function, as measured by the 22-item Sino-Nasal Outcome Test, was highly significant at three months (p < 0.0005). This improvement slightly decreased but remained significant at 6, 9 and 12 months. No side effects were noted. Endoscopic scores revealed similar and concordant improvements.
Conclusion:
Long-term low-dose trimethoprim/sulfamethoxazole therapy seems to be a safe option for selected patients. Additional randomised multicentre studies remain necessary.
