JAMA:低游离糖饮食治疗儿童非酒精性脂肪肝

2019-01-23 zhangfan MedSci原创

研究认为,对于NAFLD青少年患者,低游离糖饮食干预可显著改善患儿肝脏脂肪变性程度

目前对于儿童及青少年非酒精性脂肪肝(NAFLD)患者推荐健康饮食作为一线治疗。近日研究人员考察了低游离糖饮食对青春期NAFLD男童的治疗效果。

11-16岁,组织学确诊的NAFLD男童参与研究,患儿肝脂肪变性>10%及丙氨酸氨基转移酶水平≥45u/L,随机接受饮食干预或对照。干预组接受为期8周的低游离糖饮食,每天摄入的糖含量低于日卡路里的3%。研究的主要终点为8周后磁共振成像、质子密度、脂肪分数测量的肝脂肪变性差异。

40名男童参与研究,每组20人,平均年龄13岁,所有患儿均完成研究。饮食干预组8周肝脏脂肪变性的平均下降幅度明显大于对照组,干预组从25%下降至17%,对照组由21%下降至20%,8周差异为6.23%。12项次要终点中,饮食干预可改善5项指标,包括丙氨酸转氨酶水平和饮食依从性。干预组8周丙氨酸转氨酶水平显著降低,由103 U/L下降至61 U/L,对照组由82 U/L下降至75 U/L。未发现严重不良事件。

研究认为,对于NAFLD青少年患者,低游离糖饮食干预可显著改善患儿肝脏脂肪变性程度。
