PIANO Study
Registry of Pregnant women with IBD and their offspring to determine if IBD medications affects pregnancy and health of the baby.
- 1115 women (of which 896 delivered) were followed
- Patients on different medications (biologics, immunosuppressants) were studied and compared to unmedicated
Key findings-
IBD medication exposure during pregnancy was not associated with abnormalities in:
- Rate of congenital anomalies
- Infant height and weight
- Overall rates of infections
- Developmental milestones at months 4,9,12
Of the patients studied, those on biologics alone had a slightly increased rate of
- Spontaneous abortions
- C-sections
**These results may relate to the fact that patients with more severe disease took biologic therapies
Of the patients studied, those on combination therapy (Biologics and immunosuppressants) had a slightly increased rate of-
- Preterm birth
- Infections at 12 months
- UC: Any complication, premature delivery, low birth weight, neonatal intensive care unit
**Again, these results may be due to the aggressive disease that led to combination drug use rather than the agents themselves
