cefmatilen and Urinary-Tract-Infections

Elderly patients with urinary tract infection (UTI) are believed less likely to be cured by antimicrobial therapy than younger patients. The reasons for this poorer outcome have not yet been clarified. We have investigated the effect of antimicrobial therapy in elderly patients with complicated UTI. Four-hundred and eighty patients, 244 men and 236 women, who had complicated UTI (266 symptomatic and 236 asymptomatic) and were 20-79 years of age, were treated with one of three different drugs; one was a newer quinolone and two were oral cephems. Multivariate logistic regression analysis of treatment outcome revealed that the clinical response was significantly related to general underlying diseases and diseases of the urinary tract, but not to age, symptomatic or asymptomatic UTI, or infection site such as the kidney or bladder. We concluded that the clinical effectiveness of an antimicrobial agent was not directly related to age, and that urological examination for underlying diseases and control of them is quite important for effective treatment and control of complicated UTIs, especially in elderly patients.

S-1090, a new oral cephalosporin, was active against selected gram-negative bacteria and methicillin-susceptible clinical isolates of Staphylococcus aureus, Staphylococcus epidermidis, and Staphylococcus warneri, against which it had excellent activity. S-1090 was the most active compound against Streptococcus pyogenes and Streptococcus agalactiae among the agents compared. The in vivo efficacy of S-1090 against systemic and urinary and respiratory tract infections caused by gram-positive and -negative bacteria was superior to that expected from the in vitro and in vivo activities of the agents against which it was compared.
