Can a 35-year-old woman with AATD plan a safe pregnancy?

Question

Hello doctor,

My cousin is 35 years old and was recently diagnosed with alpha-1 antitrypsin deficiency (AATD) after several months of unexplained shortness of breath and repeated chest infections. She is now under specialist care, as her lung function is already reduced, and her doctors are also closely monitoring her liver.

Before this diagnosis, she and her husband were trying to conceive. Now she is worried that pregnancy might worsen her breathing or put extra strain on her liver. Please let us know the following:

Is pregnancy considered safe in someone with AATD, especially with existing lung involvement?
Should she consider options like IVF or fertility preservation before her lung function declines further?
She is also concerned about the genetic aspect. Can alpha-1 antitrypsin deficiency be passed on to her child?
Are there any genetic screening or testing options available before conception to assess this risk?
Additionally, she would like to know whether hormonal contraceptives (like oral pills) could negatively affect her liver or worsen her respiratory symptoms. If she were to experience early menopause due to her health condition, would hormone replacement therapy (HRT) be safe for someone with AATD?
Finally, are there any special precautions or monitoring protocols recommended during pregnancy and the postpartum period for women with alpha-1 antitrypsin deficiency?

Please help.

Thank you.

Hello,

Welcome to icliniq.com.

I read your query.

I am really sorry about your cousin’s diagnosis. Her concerns are completely valid. Pregnancy does put extra strain on the body, especially on the lungs, because as the baby grows (particularly in the third trimester), it pushes up against the diaphragm and reduces lung expansion.

This can make breathlessness worse, especially in someone who already has reduced lung function due to alpha-1 antitrypsin deficiency (AATD, a genetic condition in which the body does not make enough of a protective protein called alpha-1 antitrypsin).

That said, it is important to reassure her that many women with AATD can still have a successful full-term pregnancy. The key factor is how severe her lung disease is.

Women with mild or early-stage lung disease often tolerate pregnancy well, as long as they are closely monitored by a pulmonologist (lung specialist) and obstetrician. If her lung function improves or remains stable, she can continue trying to conceive with proper medical supervision.

Alpha-1 antitrypsin deficiency is an inherited (genetic) condition, meaning it can be passed from parents to children. The risk is higher if both partners carry the gene. If her husband is also a carrier, the child has a significant chance of being affected.

Because of this, IVF (in vitro fertilization, a medical procedure where an egg and sperm are combined outside the body in a laboratory) can be a good option. IVF allows for pre-implantation genetic testing (PGT, a special test done during IVF to check embryos for genetic problems before pregnancy starts), which means embryos can be tested for the disease before being placed in the uterus, so only unaffected embryos are selected. This helps reduce the risk of passing the condition to the child.

Estrogen-containing hormones (like combined oral contraceptive pills) are generally avoided in people with liver disease, because estrogen can put extra stress on the liver.

Safer options for her include:

Progesterone-only methods (like Levonorgestrel pills or injections).
Non-hormonal methods (like copper IUD, also known as a copper intrauterine device).

These options do not worsen lung function and are much safer for the liver.

HRT or hormone replacement therapy is a treatment that gives the body hormones (estrogen and/or progesterone) to replace the ones that decrease during menopause. It is sometimes used during menopause to relieve symptoms like hot flashes and bone loss.

In AATD:

If liver function is normal, HRT can be considered.
If liver function is impaired, HRT is not recommended.

So HRT is not automatically dangerous for her; it depends entirely on the health of her liver.

The good news is that AATD does not directly affect the ovaries. There is no strong evidence that it reduces egg reserve or causes early menopause. So she is not naturally at a higher risk of infertility or premature menopause just because of this condition.

She can safely consider pregnancy with alpha-1 antitrypsin deficiency if her lung disease is mild and well monitored. IVF with genetic testing is the safest option for avoiding transmission, and hormone treatments depend mainly on how healthy her liver is.

I hope this helps.
