Intrathecal Baclofen Pump Implantation for Type 2 Gaucher Disease.

Gaucher disease (GD) is the most common type of lysosomal storage disease, with type 2 being the most severe subtype. Type 2 GD patients suffer significant progressive neurological impairment, including spasticity, opisthotonus, seizure, and apnea. The recently developed enzyme replacement therapy (ERT) has shown therapeutic benefit for GD. However, as the enzymes do not cross the blood-brain barrier, ERT does not ameliorate neurological impairment in GD. Intrathecal baclofen therapy (IBT) is indicated for spastic neurological diseases, such as cerebral palsy, and studies have shown its therapeutic benefit in improving several manifestations of GD, such as scoliosis caused by muscle spasticity and respiratory function. To date, the potential benefits of IBT for treating lysosomal storage diseases such as GD have not been examined. Here we provide the first report of a patient with type 2 GD treated with IBT, and demonstrate its therapeutic benefit in ameliorating the neurological aspects of this disease. (C) 2017 S.
