There is no treatment or
cure for Tay-Sachs disease though there are many being studied. This
disease is always fatal. When a child is diagnosed with Tay-Sachs or
similar fatal lysosomal storage diseases, the family must decide if they
will provide palliative care and let nature take its course, or if they
will intervene medically. Though this seems like a topic of much
debate, it is often the opposite; families usually have very strong
feelings one way or the other. At the annual NTSAD conferences, it is
the rule, not the exception, that each family respects the decisions of
the other families. Everyone, however, is excited about the potential
cures that we hope the near future will bring.
Stem Cell transplantation with umbilical cord blood has been used in a
number of kids with these disorders. The difficulty of this procedure is
surviving the necessary immunosuppression prior to the transplant and
the possible graft-vs-host disease after the transplant. It also
requires family to move to the city the hospital is in for 6 to 12
months, as very few hospitals do this procedure. Many children die
during the process, but if they survive, there is hope that they will
live for many more years. It is a painful dilemma for the family
considering this option. Rachaeli was 20-months-old when she was
evaluated by the stem cell team at Duke University. At her stage in the
illness, it was predicted that she would have a 10-20 percent chance of
just surviving the transplant process. Younger children with Infantile
Tay-Sachs who have not regressed as much, and children with the
Juvenile form of Tay-Sachs and Sandhoff disease, have a better chance
of surviving. What survival means is still to be seen. The children
most definitely make the missing enzyme, Hex A in the case of Tay-Sachs
disease. Whether the enzyme crosses the blood-brain barrier to get to
the affected cells is still unclear. The prospect of "improvement",
rather than maintenance or stability, after the transplant are also
questionable. The expectation is a halting of the neurological
regression. The hope is a treatment on the horizon that will lead to
improvement or progression.
Gene therapy offers the greatest hope for a cure and it is the basket in
which most of our family's eggs are being placed... to be continued.
