ENZYME REPLACEMENT THERAPY IN TREATMENT OF MPS I

粘多糖病I，或MPSI，是由溶酶体储存障碍引起的一系列疾病。在细胞的溶酶体或消化器官中缺乏一种酶会导致大量被称为粘多糖的底物的积累。这些累积的物质在这些患者中引起严重的多系统疾病，包括智力迟钝、心脏病、呼吸系统疾病、关节僵硬、骨畸形，并常常导致死亡。本研究将评估酶替代疗法治疗MPS i的安全性和有效性，并评估酶替代疗法对肝脏、脾脏、尿液等部位溶酶体储存的安全性和影响。

Mucopolysaccharidosis I, or MPSI, is a spectrum of disorders caused by a lysosomal storage disorder. This deficiency of an enzyme in the lysosome or digestive organ of the cell leads to an accumulation of large amounts of the substrates called mucopolysaccharides. This accumulated material causes severe multisystem disease in these patients, including mental retardation, heart disease, respiratory disease, joint stiffness, bone deformity and often leads to death. This study will evaluate the safety and efficacy of enzyme replacement therapy in the treatment of MPS I. Safety and effects of the enzyme on lysosomal storage in the liver, spleen, urine and other sites as well will be evaluated.
