title: Azthreonam in the treatment of urinary tract infection: evaluation of efficacy, renal effects and nephrotoxicity.
abstract: The efficacy, renal effects and nephrotoxicity of a short course of treatment with azthreonam were evaluated in 11 adult patients with urinary tract infection. Azthreonam was administered for 5 days at a daily dose adjusted to the residual renal function of the patients. In the pre-treatment period, during treatment and 10 days after completion of therapy, urine cultures, urinalysis and routine renal function tests (clearance of creatinine, urea and uric acid) were performed and urinary enzymes (alanine-aminopeptidase, gamma-glutamyl-transpeptidase, N-acetyl-beta-D-glucosaminidase, lysozyme) were determined. Renal haemodynamics (glomerular filtration rate and effective renal plasma flow) were measured in the pretreatment period and on the 5th day of therapy. The results confirm the efficacy of azthreonam for treatment of urinary tract infection. Results of renal function tests and measurements of urinary enzymes remained unchanged during and after treatment with azthreonam. These data support the conclusion that azthreonam is an effective antimicrobial agent which does not influence renal function or cause nephrotoxic effects.
