Lancet Child Adolescent Health:Hutchinson-Gilford早衰骨成熟特征

2020-03-02 MedSci MedSci原创

研究认为,Hutchinson-Gilford早衰患者骨骼成熟和长骨生长速度高于正常数值,最终的长骨长度仅为正常值的一半

Hutchinson-Gilford早衰综合征,又称早年衰老综合症,是一种罕见的散发性遗传病,其早期临床表现是骨骼生长异常。近日研究人员就早衰患者骨骼成熟和长骨生长模式进行了研究。

在9.5年随访期间,收集20岁以下早衰患者的骨骼信息,包括手部和长骨(肱骨、桡骨、尺骨、胫骨和腓骨)的x线照片,按Greulich和Pyle标准测量骨龄。

85例早衰患者进行了250例骨骼检查。对于男女患儿,骨龄测量显示所有年龄段患儿的骨骼成熟率都高于正常数值,男孩的成熟率为1.09,女孩为1.14。1-2岁时,纵向长骨长度开始偏离正常标准,而患儿长骨的生长曲线稳定在正常最终骨长度的一半左右,生长到最终骨长度一半所需的时间也是正常标准的一半。

研究认为,Hutchinson-Gilford早衰患者骨骼成熟和长骨生长速度高于正常数值,最终的长骨长度仅为正常值的一半。
