Monotherapy with minocycline or trimethoprim/sulfamethoxazole for treatment of Stenotrophomonas maltophilia infections

摘要

Stenotrophomonas maltophilia is a Gram-negative bacillus intermittently isolated from hospitalized patients. Trimethoprim/sulfamethoxazole is considered the treatment of choice for S. maltophilia infections, though limited by toxicities. Minocycline is utilized at our institution for S. maltophilia infections due to its improved tolerability and in vitro susceptibility rates. Our objective was to evaluate the effectiveness of minocycline monotherapy compared with trimethoprim/sulfamethoxazole monotherapy for treatment of S. maltophilia infections.
