title: [Epidemiologic and therapeutic study on gonorrheal infections--one shot therapy by aztreonam].
abstract: A clinical study of a new monocyclic beta-lactam antibiotic, AZTREONAM (hereafter referred to as AZT) for gonorrheal infections as well as epidemiologic study of gonorrheal infections were made Epidemiology: There was a reflection of the increasing sexual activity of the younger generation; both male and female patients in their twenties were most frequent (male 49.5%, female 43.7%) and the percent of teen age patients was 15.1% (male) and 34.4% (female). Forty two strains (17.2%) out of 244 clinically isolated gonococci were PPNG. Residue of serious secretion was observed in a little less than 20% suggesting a complication by Chlamydia trachomatis. Clinical Result: One shot (1-2 g) therapy by AZT was given to 244 gonorrheal infection cases (212 urethritis cases of males. 32 cervicitis cases of females) with the following highly effective rate. Although beta-lactamase producing MIC of AZT at 10(6) CFU/ml showed a peak of 0.025 microgram/ml and ranged between less than 0.0125 microgram/ml to 0.2 microgram/ml. The time required for the elimination of gonococci was studied by the administration of 1 g and 2 g AZT. Gonococci became extinct in 1-8 hours or 4-4.5 hours on average. The difference between n 1 g and 2 g was scarcely observed. Clinical effect of 1 g one shot and 2 g one shot AZT was examined on the 3rd treatment day for 244 male and females cases. The effective rate was high; 90.7% by 1 g, 97.1% by 2 g for male urethritis, 100% by 1 g also by 2 g for female cervicitis. This therapeutic efficacy was kept even in PPNG, isolated cases. There were two side effects (0.8%), one case each of numbness and, redness and swelling of both hands, out of 244 cases, but both of them were minor ones without clinical complication.
