Can a bone marrow transplant help with the symptoms of Alpha-mannosidosis?
A bone marrow transplant is a type of hematopoietic stem cell transplant, or HSCT. A HSCT, replaces the missing alpha-mannosidase enzyme in people with Alpha-mannosidosis. This can improve some of the symptoms of the Alpha-mannosidosis like a large liver and spleen, frequency of infections, and hearing loss. A HSCT does not usually improve the problems with the bones, problems with the eyes, or the problems that people with Alpha-mannosidosis can have with their mental development and the brain. Since Alpha-mannosidosis is a progressive condition, having a HSCT is considered to be most beneficial early on in life. There are some reports of people with Alpha-mannosidosis having successful HCST and other reports of people with this condition not having a successful HCST. HCST also has significant risks to the person undergoing the procedure. The risks and benefits of HSCT should be discussed with your doctor.
