Aztreonam, the first of the new class of monobactams, has a narrow and specific range of bactericidal activity; it is highly active against Gram-negative aerobic pathogens but is essentially inactive against Gram-positive or anaerobic bacteria. Several unique features indicate that aztreonam may provide an attractive choice for the treatment of serious Gram-negative infection in adults and children. Clinical study in adults has shown aztreonam to be highly effective against infections of the urinary and lower respiratory tracts, the musculoskeletal system and the female genitourinary tract. It also has proved useful in neutropenic patients, including those with cancer, and for treatment of bacterial peritonitis, gonorrhea, cellulitis and wound infections. Reported clinical and microbiologic cure rates have been comparable to those associated with traditional therapeutic approaches (85 to 100%). In the treatment of children with urinary tract infection as well as other types of infections, aztreonam therapy in a dosage of 30 mg/kg given every 6 to 8 hours was associated with satisfactory clinical and microbiologic cure rates. There appear to be specific clinical situations for which aztreonam may be an appropriate alternative to more toxic therapies, although comparative trials are needed to delineate the exact place of aztreonam in the armamentarium against bacterial infection.

To determine the efficacy of aztreonam in the treatment of spontaneous bacterial peritonitis in patients with hepatic cirrhosis, 14 patients (7 males, 7 females) with 16 Gram-negative infective episodes (12 Escherichia coli and 4 Klebsiella pneumoniae) were treated with aztreonam infusions at doses of 1 gm per 8 hr for a planned 14-day period. Ages ranged from 40 to 75 years with a mean of 57 +/- 10 years. All organisms were highly susceptible to aztreonam (minimal inhibitory concentration less than or equal to 0.06 to 0.12 micrograms per ml). Serum antibiotic levels were 61.9 +/- 25.5 micrograms per ml (peak) and 27 +/- 18.5 micrograms per ml (trough). Ascitic fluid antibiotic levels were 33.6 +/- 22.5 micrograms per ml (peak) and 32.7 +/- 16.8 micrograms per ml (trough). Although the symptoms of infection were controlled within 3 days and ascitic fluid cultures became negative after 48 hr, 10 patients (62.5%) died, with hepatorenal syndrome and digestive tract hemorrhage as the principal causes of death. Three patients developed streptococcal superinfections during treatment; Streptococcus faecalis peritonitis in one case and spontaneous bacteremia due to Streptococcus equinus and Streptococcus mutans in the other two. Aztreonam was well tolerated and clinically and bacteriologically efficacious in controlling the infection. Serum and ascitic fluid levels were considerably higher than the minimal inhibitory concentration for the causative organisms, suggesting that lower doses may achieve suitable therapeutic levels. A negative aspect of the antibiotic therapy was the superinfections. The high mortality rate was attributable to the generally poor underlying condition of the patients.
