It typically takes three or four months for the corrected cells to sufficiently build up the immune system to allow a child to leave isolation. The 10th child is due to be released from the hospital this week, about four months after treatment. Those children, treated when they were 2 to 14 months old, have only been followed for 7 to 25 months, so further study will be needed to determine if there are any long-term problems. Jude and the University of California, San Francisco Benioff Children's Hospital through September 30 appear in the New England Journal of Medicine. Results from the first eight babies treated at St.

'Our patients are able to generate a healthy, fully-functional immune system and are now responding to vaccinations, and that's a first for a gene therapy trial.' Jude Children's Research Hospital in Memphis, Tennessee, said at a news conference. Ewelina Mamcarz of the bone marrow transplantation and cellular therapy center at St.

'The kids are cured because for the first time we are able to restore all three types of cells that constitute a full immune system,' lead author Dr. That child was successfully treated with a second round of gene therapy 12 months after his initial therapy.Īll have normal growth and development, and any infections they had suffered because of their disabled immune system have disappeared. Three months after treatment, non-defective immune cells appeared in all but one of the treated children. The doctors said they have skirted the leukemia problem by implanting 'insulators' around the replaced gene, preventing the treatment from accidentally activating adjacent genes and causing cancer.

Earlier versions of the treatment have been less efficient and also posed a risk of triggering leukemia. The technique replaces a defective version of a gene the body needs to build cells that seek out and destroy invading germs. Relying on the trickery used by HIV to infect people, doctors at two medical centres say they have cured 10 infants of so-called bubble boy disease, a genetic defect that leaves children, typically boys, without an immune system.
