NCT00198068

Brief Summary

The PROMISSE Study is an observational study of 700 pregnant patients, enrolled at nine major clinical centers. The purpose of the study is 1) to determine whether certain proteins (called complement split products) that can injure healthy organs can be used to predict poor pregnancy outcome in patients with systemic lupus erythematosus (SLE) and anti-phospholipid syndrome (APS), and/or 2) to determine whether elevated levels of circulating antiangiogenic factors predict pregnancy complications in patients with aPL antibodies and/or SLE.

Outcome Measures

Primary Outcomes (4)

    Neonatal death prior to hospital discharge and due to complications of prematurity

    Time of neonatal death

  • Preterm delivery prior to 36 weeks' gestation

    End of pregnancy

  • Small for gestational age (SGA) <5th %ile

    Small for gestational age (SGA) \<5th %ile in the absence of anatomical or chromosomal abnormalities and/or delivery before 36 weeks because of intrauterine growth restriction (IUGR).

    End of pregnancy

Secondary Outcomes (4)

  • Anti-β2GPI: IgG \>= 40 GPL units; IgM \>= 40 MPL units
  • For control subjects:
  • At least one successful pregnancy
  • No history of fetal death (death of conceptus ≥ 10 weeks' gestation)
  • No more than 1 miscarriage \< 10 weeks' gestation
  • No history of positive aPL in local lab or positive aPL in core labs at screening
  • Not currently a smoker
  • No medical problems requiring chronic treatment

You may not qualify if:
