To ascertain whether therapeutic equivalence exists for the treatment of paediatric community acquired pneumonia by the oral and intravenous (IV) routes.
A multicentre pragmatic randomised controlled non-blinded equivalence trial was undertaken in eight paediatric centres in England (district general and tertiary hospitals). Equivalence was defined as no more than a 20% difference between treatments of the proportion meeting the primary outcome measure at any time. 246 children who required admission to hospital and had fever, respiratory symptoms or signs and radiologically confirmed pneumonia were included in the study. Exclusion criteria were wheeze, oxygen saturations <85% in air, shock requiring >20 ml/kg fluid resuscitation, immunodeficiency, pleural effusion at presentation requiring drainage, chronic lung condition (excluding asthma), penicillin allergy and age <6 months. The patients were randomised to receive oral amoxicillin for 7 days (n = 126) or IV benzyl penicillin (n = 120). Children in the IV group were changed to oral amoxicillin after a median of six IV doses and received 7 days of antibiotics in total. The predefined primary outcome measure was time for the temperature to be <38 degrees C for 24 continuous hours and oxygen requirement to cease. Secondary outcomes were time in hospital, complications, duration of oxygen requirement and time to resolution of illness.
Oral amoxicillin and IV benzyl penicillin were shown to be equivalent. Median time for temperature to settle was 1.3 days in both groups (p<0.001 for equivalence). Three children in the oral group were changed to IV antibiotics and seven children in the IV group were changed to different IV antibiotics. Median time to complete resolution of symptoms was 9 days in both groups.
Oral amoxicillin is effective for most children admitted to hospital with pneumonia (all but those with the most severe disease who were excluded from this study). Prior to this study, the British Thoracic Society guidelines on childhood pneumonia could not draw on evidence to address this issue. This will spare children and their families the trauma and pain of cannulation, and children will spend less time in hospital.
确定口服和静脉途径治疗儿童社区获得性肺炎是否具有治疗等效性。
在英国的八个儿科中心(地区综合医院和三级医院)进行了一项多中心实用随机对照非盲等效性试验。等效性定义为在任何时间达到主要结局指标的治疗组之间的差异不超过20%。246名因发热、呼吸道症状或体征以及经放射学证实患有肺炎而需要住院的儿童被纳入研究。排除标准为喘息、空气中氧饱和度<85%、需要>20 ml/kg液体复苏的休克、免疫缺陷、就诊时需要引流的胸腔积液、慢性肺部疾病(不包括哮喘)、青霉素过敏以及年龄<6个月。患者被随机分为接受口服阿莫西林治疗7天(n = 126)或静脉注射苄星青霉素(n = 120)。静脉注射组的儿童在中位6次静脉注射剂量后改为口服阿莫西林,并总共接受7天的抗生素治疗。预定义的主要结局指标是体温连续24小时<38摄氏度且停止吸氧所需的时间。次要结局包括住院时间、并发症、吸氧持续时间以及疾病缓解时间。
口服阿莫西林和静脉注射苄星青霉素显示出等效性。两组体温恢复正常的中位时间均为1.3天(等效性p<0.001)。口服组有3名儿童改为静脉注射抗生素,静脉注射组有7名儿童改为不同的静脉注射抗生素。两组症状完全缓解的中位时间均为9天。
口服阿莫西林对大多数因肺炎住院的儿童有效(除了本研究中排除的病情最严重的儿童)。在本研究之前,英国胸科学会关于儿童肺炎的指南无法依据证据解决这个问题。这将使儿童及其家庭免受插管的创伤和痛苦,并且儿童住院时间会缩短。
