1Ayla Bashir, a 16-month-old girl from Ottowa, Canada, is healthy after doctors used a new method to treat her before she was born.
2She has a rare genetic disease that killed two of her sisters.
3The disease, called Pompe, causes the body to fail to make some or all of an important enzyme.
4But a new case study describes the new treatment method that seems to be working for Ayla.
5The young girl's parents recently told The Associated Press their daughter is now an active, happy girl who is growing normally.
6The couple previously lost two daughters, Zara, 2½, and Sara, 8 months, to the condition.
7A third pregnancy was ended because of the disease, or disorder.
8The future for Ayla is hopeful but uncertain.
9Dr. Karen Fung-Kee-Fung is a medicine specialist who works with fetuses at The Ottawa Hospital.
10She gave Ayla her treatments.
11The new method was developed by Dr. Tippi MacKenzie, co-director of the Center for Maternal-Fetal Precision Medicine at the University of California, San Francisco.
12MacKenzie shared her research with Fung-Kee-Fung.
13"We were all motivated to make this happen for this family," MacKenzie said.
14In this case, doctors delivered important enzymes to the mother through her stomach.
15The enzymes were then guided into the umbilical cord.
16Ayla received six treatments every two weeks, starting at about 24 weeks of fetal development.
17Dr. Pranesh Chakraborty has cared for Ayla's family for years.
18He told the AP that what made the treatment highly effective was completing it early, while the fetus was still developing.
19Pompe affects fewer than 1 in 100,000 newborns.
20It is caused by changes in a gene that makes an enzyme that breaks down glycogen, or stored sugar, in cells.
21When that enzyme is reduced or removed, glycogen builds up dangerously throughout the body.
22In addition, the most severely affected babies, including Ayla, have an immune condition in which their bodies block the treatment enzymes.
23This eventually stops the treatment from working.
24The hope is that Ayla's early treatment will reduce that immune response.
25Babies with Pompe disease have trouble feeding and experience muscle weakness.
26They often have very enlarged hearts.
27When left untreated, most babies die from heart or breathing problems during the first year of life.
28In addition to the girls who died, Ayla's parents have a 13-year-old son and a five-year-old daughter.
29Neither of those children were affected by the disorder.
30For now, doctors are waiting to see whether the treatment can become a generally accepted form of treatment.
31Dr. Christina Lam is a biochemical genetics specialist at the University of Washington and Seattle Children's Hospital in Seattle.
32She said it will take some time to clearly demonstrate whether the results of the new treatment are better for patients.
33Ayla receives drugs for her immune system and weekly enzyme treatments that take five to six hours.
34Unless a new method is found, Ayla is likely to continue the treatments throughout her life.
35Her parents say that every step of progress, such as when she started to crawl, has been very special.
36"It amazes us every time," said her mother, Sobia Qureshi. "We're so blessed. We've been very, very blessed."
