Living with Lupus: Controlling Flares to Help Pregnancy Flourish

Katie recently reached out to us; she told us that she has lupus and has been taking hydroxychloroquine for years to successfully manage her lupus symptoms.

Her concern? “I just found out I am pregnant and my rheumatologist was not sure if I can continue taking hydroxychloroquine during pregnancy. I am worried for my baby but I am also worried about stopping my lupus medication since it helps my symptoms so much.

I haven’t had a flare in over a year! I can suffer through the flares if I have to, but I don’t want to harm my baby. I don’t know what to do.’

Katie’s concerns about how to balance the management of her chronic health condition against her baby’s health during pregnancy are not uncommon. Generally, the healthier a person is during pregnancy, the better it is for both them and their baby. When taking medication during pregnancy, the risks and benefits of taking or not taking the medication should be carefully considered. More specifically, could the untreated condition cause more problems than taking the medication?

What is lupus and how could it affect a pregnancy?

Lupus, also known as systemic lupus erythematosus (SLE), is an autoimmune disease that affects many different parts of the body. The symptoms are variable; however, the kidneys, joints, and skin are commonly affected.  It is very important for both the health of the pregnancy as well as the health of the person who is pregnant to achieve optimal control of lupus and maintain that control without flares (relapses in symptoms) throughout the pregnancy. For those who are planning a pregnancy, it is generally advised that at least 6 months without flares reduces the chances of pregnancy-related problems.

Lupus, especially if not well controlled, can cause serious health complications for both the person who is pregnant as well as the baby. These complications include nephritis (inflammation of the kidneys that causes difficulty filtering waste from the body) and blood conditions such as anemia (a condition in which you don’t have enough healthy red blood cells to carry adequate amounts of oxygen to your body’s tissues) and thrombocytopenia (a condition in which the blood does not clot as fast as it should, which can cause excess blood loss). Inflammation in the lungs, heart, or brain can also occur and cause serious health problems.

People who have lupus also have a higher chance to develop high blood pressure during pregnancy and preeclampsia (a pregnancy-related condition that has several symptoms including a dangerous rise in blood pressure). People with lupus, most often the ones who develop high blood pressure or other health problems, may also have a higher chance of having a baby with poor growth which can lead to late miscarriage and preterm delivery (delivery before week 37).

Rare complications for the baby may include being born with symptoms of lupus (called neonatal lupus erythematosus (NLE)). These may be temporary and often disappear by six months of age. NLE is mostly seen in children when the pregnant person has anti-SSA and anti-SSB antibodies. The most serious complication of neonatal lupus is a heart rhythm problem called congenital heart block which can often be detected on ultrasound and may lead to health complications and death. If these antibodies are present, additional ultrasounds for the heart may be recommended.

Katie was surprised. ‘I thought if I stopped my medications my flares would be painful and uncomfortable, but I never thought it could seriously affect my health or the health of my baby. Can you tell me more what is known about taking my lupus medication during pregnancy?’

So what do we know about lupus medications and pregnancy?

Many medications used to treat lupus are not thought to increase risks to a pregnancy over background chances that all pregnant individuals have. Medications work differently for different people. It is very important to talk with your healthcare providers before making any changes to how you take your medication.

It is important to consider (with help of a rheumatologist) which medication works best to treat you. Regarding Katie’s question, the Society of Maternal Fetal Medicine (SMFM) recommends continuing the use of hydroxychloroquine during pregnancy. This recommendation is based on studies which did NOT show an increased risk for pregnancy related problems when hydroxychloroquine is used. Additionally, the studies showed a lower chance of lupus related problems during pregnancy when hydroxychloroquine is used.

There are many other medications such as steroids and biologics that lower the body’s immune system (immunosuppressants) that can also be considered for use during pregnancy.  However, certain medications for lupus are not recommended for use during pregnancy because they can increase the chance for birth defects and other pregnancy-related problems. SMFM recommends that methotrexate should be stopped 1-3 months before pregnancy and mycophenolate mofetil/mycophenolic acid should be stopped at least 6 weeks before attempting pregnancy. NSAIDs (non-steroidal anti-inflammatory drugs), such as ibuprofen, high dose aspirin, etc. are not recommended for use during pregnancy.

For information on specific medications make sure you talk with your healthcare provider or contact MotherToBaby and see our medication fact sheets at . It is very important to talk with your healthcare providers before making any changes to how you take your medication.

Katie summarized the information she was given very well, ‘It seems like making sure my lupus is well controlled will set both me and my baby up for the highest chance of being healthy. I feel much more comfortable continuing my medication knowing that with my own health, I am helping my baby to be healthy as well. I will talk with my healthcare providers to plan for monitoring both me and the pregnancy. Is there anything else I should know?’

Other info to know about lupus and pregnancy

It’s not uncommon for new medications to be developed for the treatment of lupus. If there is one thing that these new medications have in common, it’s that they very rarely have adequate, real-world data that describes whether the medication is safe to take during pregnancy. Pregnancy registries are the types of studies that give us this information, which is what allows us to provide risk assessments to people like Katie. That’s why we suggest to any pregnant people with lupus that they consider joining the pregnancy registry for the medication(s) they are taking if one exists. The U.S. Food and Drug Administration (FDA) maintains a list of ongoing pregnancy registry studies on their website. If you’re planning a pregnancy or are already pregnant, now is a great time to find out more about the benefits of joining a lupus pregnancy study.

People who are pregnant and have lupus will require some additional monitoring during pregnancy. They should be followed by their rheumatologist to make sure their symptoms are well controlled. Additional monitoring during pregnancy such as blood pressure checks, additional lab tests and additional ultrasounds may be recommended. Make sure you talk with your healthcare provider to discuss the management plan for your pregnancy.

Katie returned to MotherToBaby a few weeks later and told us she has been working together with her rheumatologist as well as her obstetric team including a high-risk pregnancy provider (also called Maternal Fetal Medicine (MFM) specialist) to make sure both her and her baby are as healthy as they possibly can be. ‘I felt empowered by being informed, having all my healthcare providers in my corner and knowing that by taking care of myself, I am taking care of my baby too. Thank you, MotherToBaby!’.

If you are pregnant and taking belimumab (Benlysta®) to treat SLE or lupus nephritis, please consider enrolling into our observational study. This study will give people with lupus better answers about how lupus and its management can affect a pregnancy and a developing baby. You will not be asked to take or change any medications, and you can participate from the comfort of your home.
