We examined 134 pediatric clinical isolates of Enterobacteriaceae, Pseudomonas aeruginosa, and gram-positive cocci for susceptibility to aztreonam alone and in combination with seven other antibiotics. All 98 gram-negative isolates were susceptible to aztreonam with similar inhibitory and bactericidal activity. Combinations of aztreonam with cefoxitin, ampicillin, or clindamycin were generally indifferent or additive. Synergism was occasionally seen against enteric organisms with aztreonam plus cefoxitin or clindamycin. Combinations of tobramycin and aztreonam were synergistic (62%) against P. aeruginosa; aztreonam plus piperacillin or ticarcillin was additive. Aztreonam did not affect the activity of nafcillin against Staphylococcus aureus, or of ampicillin against species of Streptococcus group B or D. Antagonism was seen only with aztreonam plus cefoxitin against Enterobacter species, but not at clinically significant concentrations. Several combinations of antibiotics with aztreonam should be appropriate for initial therapy of infections in children without major risks of antibacterial antagonism.
我们检测了134株儿科临床分离的肠杆菌科细菌、铜绿假单胞菌和革兰氏阳性球菌对氨曲南单独使用以及与其他七种抗生素联合使用时的敏感性。所有98株革兰氏阴性菌分离株对氨曲南敏感,且具有相似的抑菌和杀菌活性。氨曲南与头孢西丁、氨苄西林或克林霉素联合使用时通常表现为无关或相加作用。氨曲南加头孢西丁或克林霉素偶尔对肠道菌有协同作用。妥布霉素与氨曲南联合使用对铜绿假单胞菌有协同作用(62%);氨曲南加哌拉西林或替卡西林为相加作用。氨曲南不影响萘夫西林对金黄色葡萄球菌的活性,也不影响氨苄西林对B组或D组链球菌的活性。仅在氨曲南加头孢西丁对肠杆菌属细菌时观察到拮抗作用,但在临床有效浓度时未观察到。几种氨曲南与抗生素的联合用药应适用于无明显抗菌拮抗风险的儿童感染的初始治疗。
