| Outline of Final Research Achievements |
In this study, we investigated the efficacy and safety of pentosan polysulfate in patients with mucopolysaccharidosis about joint symptoms. For adult patients with mucopolysaccharidosis, pentosan polysulfate was injected subcutaneously and safety and therapeutic effects were examined. For 3 adult patients with mucopolysaccharidosis type II, subcutaneous injection of pentosan polysulfate was performed once a week for 12 weeks. After administration of pentosan polysulfate, one patient improved joint pain, and three patients showed mild improvement in the range of joint movement of the shoulder joint. Side reactions were not observed except for mild internal bleeding at the site of subcutaneous injection. Urinary uronate excretion after administration of polysulfate pentosan decreased with one who stopped enzyme replacement therapy. It was considered to act on subcutaneous injection of polysulfate pentosan.
