NCT00194987

Brief Summary

The purposes of this study are to provide medical management by giving treatment to the mother that will bring up the fetal platelet count and to minimize the number of invasive procedures to the fetus (which may result in serious fetal injuries).

Outcome Measures

Primary Outcomes (1)

  • Number of Newborns With a Birth Platelet Count > 50,000/uL

    this uses the birth platelet count of the fetuses from the study when they are born

    32-40 weeks (the endpoint is the birth which is not at the same number of weeks for all of the babies. This is why the weeks are not listed specifically eg week 40

Secondary Outcomes (2)

  • Intracranial Hemorrhage: Number Occurring in Fetuses and Newborns of Mothers in Study

    time of ICH (range 20-40 wks)

  • Number of Fetal Platelet Counts > 50,000/uL

    32 +/- 2 weeks

Study Arms (2)

IVIG x 2

EXPERIMENTAL

IVIG 2 g/kg/wk divided into 2 infusions per week for women with a fetus affected by FNAIT

Drug: IVIG (Intravenous Immunoglobulin)

IVIG x 1 + prednisone

EXPERIMENTAL

IVIG 1 g/kg/wk in 1 infusion per week + prednisone 0.5 mg po daily for women with a fetus affected by FNAIT

Drug: IVIG (Intravenous Immunoglobulin)Drug: prednisone

Interventions

one gram per kg of IVIG per infusion given either once or twice

IVIG x 1 + prednisoneIVIG x 2

in arm with IVIG 1 gm/kg/wk will also receive prednisone 0.5 mg/kg/day

IVIG x 1 + prednisone

Eligibility Criteria

Age18 Years - 50 Years
Sexfemale
Healthy VolunteersNo
Age GroupsAdult (18-64)

You may qualify if:

  • are PLA-1 (platelet antigen A1) negative and have known platelet incompatibility with their fetus
  • have had a previous child who suffered an antenatal hemorrhage prior to 28 weeks gestation (as best as could be estimated)
  • are less than 19 weeks gestation
  • are PLA-1 negative and have known platelet incompatibility with the fetus
  • have had a previous child who suffered an antenatal hemorrhage after 28 weeks gestation (as best as could be estimated)
  • are between 12-30 weeks gestation
  • are PLA-1 negative and have known platelet incompatibility with the fetus
  • have not had a previous child who suffered an antenatal hemorrhage
  • are between 20-30 weeks gestation

You may not qualify if:

  • have had a previous child who suffered an antenatal hemorrhage after 28 weeks gestation
  • are greater than 19 weeks gestation
  • have had a previous child who suffered an antenatal hemorrhage prior to 28 weeks gestation
  • are greater than 30 weeks gestation
  • have had a previous child who suffered an antenatal hemorrhage
  • are greater than 30 weeks gestation
