Women who have blood type O, A, B or AB negative need to be aware when they are mothers, warn experts. If the partner has the RH factor positive and transmit this characteristic to the baby, the woman's body may reject the child and produce antibodies against the fetus, leading to illness and even death.
- For the mother to produce these antibodies, the blood of the baby needs to contact her blood. In the first trimester of pregnancy, the chance of this happening is only 3%. At delivery, is 70%. So at first pregnancy the baby is usually not affected, because the antibodies arise only at birth - explains the scientific director of the Brazilian Institute for Assisted Reproduction, Julian Scheffer.
Nevertheless, we must make a special monitoring through a test called indirect Coombs. If there is suspicion of incompatibility, the obstetrician may recommend a blood transfusion for the baby in the womb, in severe cases.
Vaccine to protect the second son
After the birth of their first child, is done examining blood type of the baby to see if he has the RH factor positive. If the suspicion is confirmed, the mother should take a vaccine that inhibits the production of antibodies.
- The treatment reduced mortality in case of incompatibility with the second child, 90% to about 30%. But this rate is still high - Shceffer says.
Another type of mismatch that affects 10% to 15% of couples is called the ABO isoimmunization: a woman who has type O blood and a man of type A, B or AB.
- It is a milder reaction with jaundice (yellowing of the eyes) and mild anemia - says the director of the Life Fertility Center Network D'Or, Maria Cecilia Erthal.
Remedy made with her husband's blood
A third problem that leads to repeat abortions is lack of compatibility between the blood and the woman's husband's genetic material. There are no definite causes for rejection and treatment divides experts.
- Is a vaccine made from immune cells from the blood of man. This medication is applied to the woman. It's called crossmatch. This technique is not yet fully accepted as lacking scientific evidence of its effectiveness - ponders Julian Scheffer.
Gisella lawyer for Smith, the treatment brought two small gifts.
- I aborted three times in two years. Just after treatment, could be a mother.
'I found the vaccine. It was a hard time '
Luciana Schlobach
37, an architect, had incompatible blood
I knew I could have some incompatibility in pregnancy, because my mother had passed through it. When I discovered I was expecting my first child, I told the doctor soon. My blood is O negative and my husband's positive. After delivery, I took the vaccine, still in the hospital. In the second pregnancy, prenatal care did but when it came time to get the vaccine again, I could not find anywhere. It was a hard time getting up. I was worried, but he was born perfect, thank God.
