黏多糖贮积症患者的角膜混浊度随时间的客观量化改变

该前瞻性队例研究对9名患有MPS Ⅰ或MPS Ⅵ的患者进行研究,目的在于确定黏多糖贮积症(MPS)患者在接受酶替代疗法或造血干细胞移植治疗时,其角膜混浊程度随时间发生的客观变化。

采用虹膜相机和全眼科检查对角膜混浊程度进行量化,包括在2011年进行并于2015年/2016年再次进行的角膜混浊程度的主观评价;同时利用生物标记物,如硫酸皮肤素/硫酸软骨素比(DS/CS),对角膜混浊程度进行评价。在对患者随访的60个月内,采用虹膜相机角膜混浊测量评分系统(COM)评估角膜混浊的改变。

结果发现,5/17(29%)眼的COM评分恶化,显示角膜混浊度增加。而在10/17眼的COM评分中未发现明显改变。其中1个患者(2/17眼)的角膜清晰度明显改善,其改善程度与生物标志物检测结果的改善程度具有相关性。

虹膜相机的COM评分系统是监测MPS患者角膜混浊程度随时间变化的有效客观手段,或可通过有效的治疗逆转角膜混浊的症状,而治疗的有效性或可通过生物标志物进行监测。
