[Bacteriological study on fosfomycin against organisms clinically isolated from paranasal sinusitis]
The Japanese Journal of Antibiotics
|August 1, 1991
Summary
Fosfomycin (FOM) nasal solution effectively eradicated common bacteria causing paranasal sinusitis. This study confirms FOM
Area of Science:
- Microbiology
- Pharmacology
- Otolaryngology
Background:
- Paranasal sinusitis is frequently caused by bacterial infections.
- Topical antibiotic preparations are crucial for managing sinonasal infections.
Purpose of the Study:
- To evaluate the in vitro antibacterial activity of fosfomycin (FOM) nasal solution.
- To determine the efficacy of FOM against clinical isolates from paranasal sinusitis patients.
Main Methods:
- Bacteriological and clinical studies conducted across multiple centers from 1988 to 1990.
- Isolation, identification, and drug susceptibility testing of bacterial strains from 396 sinusitis cases.
- Determination of Minimum Inhibitory Concentrations (MIC50 and MIC80) for FOM.
Main Results:
- Streptococcus spp. (25.7%), Staphylococcus spp. (21.7%), and anaerobic Gram-positive cocci (13.6%) were the most frequently isolated bacteria.
- FOM demonstrated potent activity against 354 clinical isolates, with MIC50 of 12.5 µg/ml and MIC80 of 25 µg/ml.
- High eradication efficacy was observed against common causative organisms of paranasal sinusitis.
Conclusions:
- Fosfomycin nasal solution exhibits significant antibacterial activity against key pathogens of paranasal sinusitis.
- FOM nasal solution is a potentially effective topical treatment for paranasal sinusitis.
- The study supports the use of FOM as a targeted therapy for sinonasal bacterial infections.
