Brief Summary

Rare diseases frequently affect women of childbearing age. Pregnancy in these women has become less rare, but remains associated with high levels of complications. One obstacle to their optimal management during pregnancy is that there are no prospective studies of pregnancy during rare diseases and several connective tissue diseases. As a consequence, the management of these pregnancies is non-standardised in terms of treatment, monitoring (frequency of consultations, laboratory tests and ultrasound), and organisation of care. Moreover, although these women (all diseases combined) are frequently exposed to medications potentially incompatible with pregnancy, little is known about the frequency of these exposures and especially their consequences to mother and child. For these reasons, researchers and clinicians from different specialties created an interdisciplinary research group on pregnancy and rare diseases (GR2), intended to improve the management of these patients' pregnancies. Using a single computer server, the investigators plan to set up a large prospective study of pregnancies in patients with rare diseases: various forms of myositis, lupus, antiphospholipid syndrome, Sjogren syndrome, scleroderma, and inflammatory rheumatic diseases. The investigators objective is to analyse the complications of pregnancies in women with rare diseases and then to improve their management and their quality of life.

Outcome Measures

Primary Outcomes (1)

  • "good" obstetric outcome

    It's a composite outcome . A pregnancy with no severe maternal complication (by the Epimoms\* definition), live birth after 35 weeks' gestation, a birth weight \>10th percentile of the general population and no infections (maternal and infant) during pregnancy and first year of follow up, respectively

    35 week gestation until 1 year Post Partum

Secondary Outcomes (3)

  • Define the best therapeutic management strategies

    2 years

  • Conduct pharmacoepidemiologic studies

    2 years

  • Analyse the frequency of exposure to various medications (immunosuppressors, biological therapy, corticosteroids) and their maternal and fetal consequences (e.g., infectious complications).

    9 months
