Pregnant Women With Previous Child With Cardiac Neonatal Lupus
400 mg/day Hydroxychloroquine Hydroxychloroquine: women meeting eligibility criteria will receive 400mg per day of HCQ beginning as soon as pregnancy is established and informed consent obtained. Mothers already on HCQ will remain on 400mg, or escalate to 400mg if on 200mg. Hydroxychloroquine is taken in 200mg pill form - 400mg = 2 200mg pills.

Recurrence of Advanced Heart Block
5 Participants

SECONDARY outcome

Timeframe: After enrollment at 16-18 weeks gestation, then weekly until 26 weeks, biweekly to 34 weeks, at birth (approximately 9 months), and at one year follow up (approximately 21 months from enrollment)

EKG at birth must confirm 1st degree AV block. It is also possible that a fetus developing 1st degree block on study medication might have developed more advanced block in the absence of study medication.

Echocardiographic Densities Consistent With EFE Confirmed Postnatally
0 Participants

SECONDARY outcome

Timeframe: Up to 9 months

An autopsy with full evaluation of the heart will be encouraged but cannot be mandated. If AV block or evidence of a cardiomyopathy can be "proven," then these will provide the basis for final categorization. If not possible, the death will not be considered a recurrence rate but will be reported.
