JAMA Pediatr:囊肿性纤维化儿童的行为和营养治疗

2015-05-10 MedSci MedSci原创

 对于患有囊肿性纤维化的患者来说,幼年早期是优化生长发育的关键时期。一项采用了美国囊肿性纤维化基金(CFF)的数据的前瞻性研究表明在四岁时更高的体重和身高比重与十八岁时增长的存活时间有关。随后CFF确定了学龄前儿童(即2-5岁)的新的照护指南。三个焦点领域之一就是营养,并且一项主要的建议急切需要临床研究的证据。 为了检验在2-6岁的囊肿性纤维化患者接受行为和营养治疗(简称BEH

对于患有囊肿性纤维化的患者来说,幼年早期是优化生长发育的关键时期。一项采用了美国囊肿性纤维化基金(CFF)的数据的前瞻性研究表明在四岁时更高的体重和身高比重与十八岁时增长的存活时间有关。随后CFF确定了学龄前儿童(即2-5岁)的新的照护指南。三个焦点领域之一就是营养,并且一项主要的建议急切需要临床研究的证据。

为了检验在2-6岁的囊肿性纤维化患者接受行为和营养治疗(简称BEH)是否更优于教育和注意力控制治疗。研究人员假设BEH更优于对照组(即教育和注意力控制治疗组)。BEH疗法可以带来(1)更好的能量摄取、(2)治疗前后6个月体重z评分(WAZ)提升、(3)从治疗前到跟踪随访的18个月的身高z评分(HAZ)提升。

从2006年1月到2012年11月,共有78名年龄在2-6岁的患有囊肿性纤维化和胰腺功能不全的儿童参与此次随机、多中心的临床试验,其中干预组36人,对照组42人。行为干预结合个体化营养咨询服务靶向性地增加能量摄取,并且训练管理技能。对照组提供教育以及作为注意力和接触频率的行为的安慰剂对照。两组治疗都是经人或者电话传递,前八周每周一次,后面四个月每月一次。治疗前后,干预组每日能量摄取增加了485卡路里,对照组增加了58卡路里。WAZ分别增加了0.12单位和0.06单位。HAZ增加分别为0.09和-0.02。

此次研究表明,行为和营养干预治疗可以提高能量摄取和身高z评分结果。这说明这一治疗可以作为一种有效的干预手段用于治疗学龄前儿童的囊肿性纤维化。

研究人员称:在囊肿性纤维化患者引起其肺部感染的细菌种类日益增多,这些细菌可以通过人与人之间进行传播的,尽管可能不是直接接触性的传播。 据在英国 Hinxton,威康信托桑格研究所(Wellcome Trust Sanger Institute)的博士朱利安·帕克希尔(Julian Parkhill)及其同事们称:分离来自感染囊性纤维化患者的集中性脓肿分枝杆菌的基因组分析发现几乎没有序列的差异。事
