Overview
Research Projects
Researchers are currently directing
their efforts toward the development of improved and novel treatments.
Studies are ongoing to determine the long-term safety and efficacy
of enzyme therapy, indications for the treatment of Gaucher disease,
and the value of treatment of asymptomatic patients.
Another area in which studies are now underway is the evaluation of
bone marrow transplantation for the treatment of this disease. Although
this approach can cure Gaucher disease, there is a high morbidity and
mortality rate associated with this procedure; thus only severely affected
patients who have histocompatible sibling donors have been considered
for transplantation.
Gene therapy is another approach to the cure of Gaucher disease. By
using any of several techniques, a normal gene for acid b-glucosidase
can be inserted in to the somatic cells of Gaucher disease patients
to correct the inherited enzyme defect. The basic strategy involves
the retrieval of stem cells from the patient through either bone marrow
harvesting or extraction from peripheral blood, and the subsequent introduction
of the normal gene using a retroviral vector. Stem cells are blood cells
with the ability to propagate continuously; thus, once the deficiency
is corrected in these cells they become an internal and continual source
of the enzyme.
