[Clinical reevaluation of aztreonam (AZT) on urinary tract infections].

The clinical effectiveness and safety of Aztreonam (AZT) were studied in 55 patients with complicated urinary tract infections. AZT was administered at a dose of 4 g/day for 5 days. The results as evaluated by the UTI criteria were excellent in 8 cases, moderate in 26 and poor in 21. The overall effectiveness rate was 61.8%. Out of 64 strains of bacteria isolated before treatment, 50 strains (78.0%) were eradicated by the treatment. Bacteriological eradication rates for gram negative rods and gram positive cocci were 79.6% and 66.7%, respectively. There were no obvious side effects, except for a temporary elevation of glutamic oxaloacetic transaminase, glutamic pyruvic transaminase alkalinephosphatase, and total bilirubin in some patients. The results indicate that AZT tablets are useful and safe for the treatment of complicated urinary tract infections.
