Pregnancy after a vasculitis diagnosis is linked to increased pregnancy loss and preterm birth rates in women. Vasculitis activity typically did not worsen during pregnancy for most patients.
Area of Science:
- Rheumatology
- Obstetrics & Gynecology
- Clinical Research
Background:
- Pregnancy outcomes in patients with vasculitis are not well-documented.
- Understanding these outcomes is crucial for patient care and counseling.
Purpose of the Study:
- To assess pregnancy outcomes in individuals diagnosed with vasculitis.
- To investigate the impact of disease diagnosis timing on pregnancy outcomes.
Main Methods:
- An anonymous online survey was distributed to patients in the Vasculitis Clinical Research Consortium Patient Contact Registry.
- Survey data included pregnancy outcomes, timing of conception relative to vasculitis diagnosis, and medication use.
Main Results:
- Women conceiving after a vasculitis diagnosis had higher rates of pregnancy loss (33.8%) and preterm birth (23.3%) compared to those conceiving before diagnosis (22.4% and 11.4%, respectively).
- Most women (82%) did not report worsening vasculitis during pregnancy, but increased activity correlated with preterm delivery.
- Medication exposure (cyclophosphamide, prednisone) did not show a significant impact on outcomes due to small sample sizes.
Conclusions:
- Conceiving after a vasculitis diagnosis is associated with poorer pregnancy outcomes, including increased pregnancy loss.
- Vasculitis generally remained stable during pregnancy for the majority of patients studied.
