  • BACTERIAL AND CLINICAL STUDY ON AZTHREONAM IN GONORRHEA

抄録

The purpose of this study was to determine the susceptibility of N. gonorrhoeae to Azthreonam (AZT). The MIC of AZT against 64 strains of N. gonorrhoeae was examined, and all strains showed MIC of 5 0.78μg/ml, including 7 β-lactamase producing strains.<BR>The effect of treatment with AZT was compared in 86 patients with uncomplicated gonorrhea.<BR>A single-dose regimen of 1.0g AZT i. m., a two-dose regimen of 1.0g and 1.0g, and a three-dose regimen of 1.0g, 1.0g and 1.0 g (one day apart) were given. Three group regimens were equally effective with an overall cure rate of 100%. In patients harbouring β-lactamase producing gonococci the infection was cured.<BR>During the follow-up (7 days after treatment) of 48 patients postgonococcal urethritis (PGU) was diagnosed in 13 (27.1%) patients. Seven (77.8%) out of 9 patients with Chlamydia trachomatis positive cultures who were followed up developed PGU, while only 6 (15.4%) of 39 patients with Chlamydia trachomatis negative culture developed PGU. No subjective side effects were observed.
