Can women with AATD have a safe pregnancy?

Question

Hello doctor,

I am 29 years old and was recently diagnosed with alpha-1 antitrypsin deficiency (AATD). I also have early signs of lung involvement, and I want to understand how this might affect my fertility and future pregnancy plans.

Questions I have:

Is it safe for women with AATD to get pregnant?
Could the increased pressure on the lungs during pregnancy worsen my symptoms?
Can AATD or the infusions I am receiving affect the baby in any way?
My doctor advised avoiding estrogen-containing birth control. Is this due to potential liver involvement?
What safer contraceptive options are recommended for women with AATD?
My periods are heavy and irregular. Could AATD affect clotting or hormonal balance?
Would IVF or other fertility treatments carry additional risks because of the liver or immune aspects of my condition?

I would appreciate your guidance on how to plan for pregnancy safely with AATD.

Please help.

Thank you.

Hi,

Welcome to icliniq.com.

Alpha-1 antitrypsin deficiency (AATD, a genetic condition where your body does not make enough of a protein called alpha-1 antitrypsin) can be challenging to manage because it affects multiple organs, mainly the lungs and liver. However, women with AATD can have successful pregnancies, depending on the severity of the disease.

If your lung function and liver function are adequate, you should generally be able to cope with pregnancy. For individuals with moderate to severe disease, pregnancy may carry higher risks, and sometimes doctors may recommend delaying or avoiding pregnancy.

That is why it is important to see your pulmonologist (lung specialist) and hepatologist (liver specialist) to understand the extent of organ involvement. Since you mentioned your disease is mild, pregnancy is likely to be safe for you.

During pregnancy, the lungs experience extra pressure, especially in the third trimester, because the growing uterus pushes on the diaphragm and lungs. In women with AATD, this pressure can be slightly higher, but it is generally manageable with pulmonary support, so it should not prevent you from carrying a pregnancy if your disease is mild.

AATD is a genetic condition, meaning it can be passed to your child if both parents carry the gene. Even if your child inherits it, the disease usually does not cause serious problems in childhood.

The infusions you are receiving (alpha-1 protein replacement therapy) are generally continued during pregnancy, as there is no evidence suggesting harm to the developing baby.

For contraception, progesterone-only options (like pills, implants, or intrauterine devices) are preferred for women with AATD, because estrogen-containing contraceptives can stress the liver.

Regarding IVF (in vitro fertilization), it is not riskier for you. In fact, IVF offers the possibility of preimplantation genetic testing, which can check embryos for AATD before transfer, giving you more control over passing the condition to your child.

Overall, with mild AATD, most women can expect a fairly normal pregnancy and delivery. Regular monitoring of your lungs and liver throughout pregnancy will help ensure the best outcome for both you and your baby.

I hope this helps.
