- A two-month-old girl has become the youngest to receive bone marrow transplant from an unrelated donor.
- The baby was diagnosed with ‘bubble baby syndrome’.
ABOUT BUBBLE BABY SYNDROME
- It is also known medically as severe combined immunodeficiency (SCID).
- It’s a very rare genetic disorder that causes life-threatening problems with the immune system.
- Babies with SCID are born without an immune system, making them vulnerable to life-threatening infections.
- The genetic defect linked to SCID leads to a deficiency in Lymphocytes (type of White blood cells), which are a crucial component of our immune system.
- Two main types of Lymphocytes –
- T cells identify, attack, and kill “invaders.”
- B cells make antibodies that “remember” an infection for future protection against infections.
- Without a bone marrow transplant, most children with SCID succumb to infections before reaching their first birthday.
- The only cure for a bubble baby syndrome is a bone marrow transplant from a healthy donor. The transplant replaces the child’s faulty immune system with a healthy one.
ABOUT BONE MARROW TRANSPLANT
- A bone marrow transplant is also called a stem cell transplant or, more specifically, a hematopoietic stem cell transplant.
- It can be used to treat certain types of cancer, such as leukemia, myeloma and lymphoma, and other blood and immune system diseases.
- Bone marrow transplants may use cells from the same person (autologous transplant) or from a donor (allogeneic transplant).
