Abstract
Patients with Gaucher disease type 3 (GD3), especially those with GBA p.L444P homozygous mutation, often suffer from complications including lymphadenopathy even under regular enzyme replacement therapy (ERT). In order to improve their outcome, we administrated eliglustat, a substrate reduction therapy (SRT), in combination with ERT to four patients, age ranged 9–18 years, for two years. The results revealed that patients' plasma glucosylsphingosine (lyso-GL1) level and chitotriosidase activity both decreased after adding eliglustat. In three patients who completed follow-up MRI scanning, sizes of lymph nodes all decreased. No severe adverse events were attributed to eliglustat. Therefore, our data suggest that a combined SRT and ERT treatment may improve the ERT-resistant symptoms in patients with GD3.
