As an IBD mom I see it as a responsibility and an opportunity to participate in research studies while I am pregnant and as my children grow. I’m currently 20 weeks pregnant (tomorrow!) with my third baby and this time around I’m enrolled in the Pregnancy in Inflammatory Bowel Disease and Neonatal Outcomes (PIANO) study. The project was conceived, lead, and executed by Dr. Uma Mahadevan, Professor of Medicine at the University of California San Francisco in 2007.

Since the project launched, more than 1,800 women have participated in the registry. Of that number, over 900 stayed on biologics throughout their pregnancies. I’m thrilled to be a part of this initiative. If my pregnancies and children can provide clarity for a future generation of IBD moms, the extra effort on my part is more than worth it. Thanks to women before me who have been on a biologic and been a part of research while pregnant, I have peace of mind knowing that staying on my Humira is best for me and for baby.

Without studies that indicate how babies in utero respond to medication exposures we would be in the dark about what is best for mom and baby not only during pregnancy, but with breastfeeding.

“There is so much misinformation about pregnancy and IBD including being told not to conceive at all or to stop medication. This is incorrect and dangerous. PIANO was started to provide reliable data for women with IBD considering pregnancy so they and their providers can make an informed choice for themselves and their babies,” said Dr. Mahadevan. “Every pregnant woman with IBD has benefited from the generosity of PIANO moms who contributed their outcomes, good or bad, to the pool of knowledge we have. Every PIANO mom who contributes benefits not herself, but future mothers with IBD. It is an invaluable and precious gift.”

What PIANO measures

There are four main areas the PIANO study looks at:

1. Whether the level of biologic drug transferred across the placenta to the infant by the time of birth predicts the risk of infection or other adverse outcomes
2. Whether the achievement of developmental milestones is affected by medication exposure
3. Whether the rates of birth defects, adverse pregnancy outcomes and complications of labor and delivery are affected by IBD medications
4. Whether second trimester drug levels can be used to adjust drug and minimize transfer across the placenta to the baby

Since I am just now reaching the halfway point of my pregnancy, I have only had to fill out questionnaires. You are required to do so during each trimester, at the end of your pregnancy, and then at 4, 9, and 12 months post-delivery. Along with that, you can provide follow up until your child is 18, once a year. During this trimester I will also provide blood work and a fecal calprotectin. On delivery day, bloodwork will be taken from me, my baby, and my umbilical cord. Depending on my son’s blood work at delivery, I may be asked for more when he’s 3 and 6 months. If at any time I am not comfortable with him getting his blood drawn, I can always opt out. The cord blood is similar to the baby blood at birth so that is adequate. I can also choose to stop the annual questionnaire at any time.

If a woman receives the COVID-19 vaccine during pregnancy, the PIANO study is also measuring the antibody levels found in the cord blood (on the day of birth) to confirm that the benefit transfers to the baby. Breastmilk will also be measured for the transfer of protective antibody against COVID.

The Findings Thus Far

In a presentation this past fall, Dr. Mahadevan shared findings from PIANO.

“We looked at pregnancy, birth and developmental outcomes in the infants at one year, based on exposure to drug, and found no increase in negative outcomes and no reduction in developmental milestones. Biologic‑exposed infants did have some statistically increased improvement in developmental milestones compared to the unexposed group. Overall, what this study suggests is that women with inflammatory bowel disease should continue their biologics and thiopurines throughout pregnancy to maintain remission, given no evidence of harm, and evidence that  disease activity can increase miscarriage.”

The study also found that disease activity can increase preterm labor and birth, all the more reason for women to stay on their medication and not try and go med-free while pregnant.

Looking to the Future

Currently, there is no end date for the study. As long as there is funding, the project will continue. Dr. Mahadevan says with all the new medications coming down the pipeline there is a need for safety data. She says, “The infrastructure of PIANO allows us to study new medications as they come to market, even before they are approved for IBD.”

To participate in the study women must have IBD and live in the United States. Interested in learning more or getting enrolled? Email PIANO@ucsf.edu or call 415-885-3734.
