Urinary tract infections are quite frequent in children. Urinary tract obstruction combined with recurrent urinary tract infections increase the risk for renal impairment. Therefore prophylaxis of reinfection is an important nephroprotective procedure. The aim of this open, controlled, randomised pilot study was to compare the efficacy and tolerance of a low dose prophylaxis with Cefixime versus Nitrofurantoin. 60 girls aged 1 to 11 years with at least 2 urinary tract infections within the preceding year were included in the study. The minimum duration of therapy was 6 months and was extended to 12 months for most of the children. The number of recurrent infections was the main criteria for efficacy evaluation, whereas adverse events were analysed to evaluate tolerance. Statistical significant differences between the two treatment groups, regarding recurrence rates could not be demonstrated. Tolerance was comparable in both groups. The influence on gut flora of cefixime given as a low dose regimen over a long period of time corresponds with already published results and was not correlated with a higher number of gastrointestinal side effects.
Low-dose Cefixime (2 mg/kg bodyweight) is effective and well tolerated in the prophylaxis of recurrent urinary tract infections. Efficacy and tolerance of cefixime were comparable to the results obtained with nitrofurantoin. Due to the small number of patients this study was only a pilot study. Low-dose cefixime, however, could become an alternative to standard regimens in the prophylaxis of recurrent urinary tract infections. This should be investigated in further studies.
尿路感染在儿童中相当常见。尿路梗阻合并反复尿路感染会增加肾功能损害的风险。因此,预防再感染是一项重要的肾脏保护措施。本开放性、对照、随机试点研究的目的是比较低剂量头孢克肟与呋喃妥因预防用药的疗效和耐受性。该研究纳入了60名年龄在1至11岁之间、前一年至少有2次尿路感染的女孩。治疗的最短持续时间为6个月,大多数儿童延长至12个月。反复感染的次数是疗效评估的主要标准,而通过分析不良事件来评估耐受性。在复发率方面,两个治疗组之间未显示出统计学上的显著差异。两组的耐受性相当。长期低剂量方案使用头孢克肟对肠道菌群的影响与已发表的结果一致,且与更多的胃肠道副作用无关。
低剂量头孢克肟(2mg/kg体重)在预防反复尿路感染方面有效且耐受性良好。头孢克肟的疗效和耐受性与呋喃妥因的结果相当。由于患者数量较少,本研究只是一项试点研究。然而,低剂量头孢克肟可能成为预防反复尿路感染标准方案的替代方案。这一点应在进一步的研究中进行调查。
