[Clinical evaluation of combination therapy of sulbactam/cefoperazone and aminoglycoside in respiratory tract infections]

Abstract

We compared clinical efficacy and safety of sulbactam/cefoperazone (SBT/CPZ) with those of SBT/CPZ combined with aminoglycoside (amikacin (AMK), tobramycin (TOB), etc.) in treatment of respiratory tract infections in patients with underlying respiratory diseases, with cancer, or with acute exacerbation of chronic respiratory infections. Clinical evaluations of monotherapy with SBT/CPZ in a total of 30 patients showed excellent results in 5, good results in 17. Clinical effects of combined therapy of SBT/CPZ plus different aminoglycosides in a total of 33 patients were excellent in 18, good in 5. The efficacy rates (excellent plus good) were 73.3% in the monotherapy and 69.7% in the combined therapy. AMK was used concomitantly with SBT/CPZ in 16 of 33 patients. Clinical effects of SBT/CPZ plus AMK were excellent in 10, good in 3, and the efficacy rate was 81.3%. Bacteriological effects were evaluable against 11 strains in the monotherapy group, and against 17 strains in the combined therapy group. The eradication rates were 54.5% in the monotherapy group, and 81.3% in the combination therapy group. Diarrhea was observed in a patient who received the monotherapy. Abnormal laboratory test results were observed on in 5 patients who received the monotherapy, and in 4 patients who received one of the combined therapies. All abnormalities disappeared after the completion or discontinuation of therapies. We considered SBT/CPZ combined with an aminoglycoside is a useful chemotherapy for respiratory tract infections in patients with underlying diseases and acute exacerbation of chronic respiratory tract infections.
