Pregnancy
Overview
Twenty-five years ago, women with
lupus were counseled not to become
pregnant because of the risk of a flare
of the disease and an increased risk
of miscarriage. Research and careful
treatment have made it possible for
more and more women with lupus to
have successful pregnancies. Although
a lupus pregnancy is still considered
high risk, most women with lupus are
able to carry their babies safely to
term. Experts disagree on the exact
numbers, but approximately 10 percent
of lupus pregnancies end in miscarriage.
Pregnancy counseling and planning
before pregnancy are important.
Optimally, a woman should have no
signs or symptoms of lupus before she
becomes pregnant.
Researchers have identified two
closely related lupus autoantibodies,
anticardiolipin antibody and lupus
anticoagulant, that are associated with
risk of miscarriage. One-third to onehalf
of women with lupus have these
autoantibodies, which can be detected
by blood tests. Identifying women
with the autoantibodies early in the
pregnancy may help physicians take
steps to reduce the risk of miscarriage.
Pregnant women who test positive for
these autoantibodies and who have had
previous miscarriages are generally
treated with baby aspirin and heparin
throughout their pregnancy.
While it used to be said that flares, if
they occurred, were more frequent
postpartum, they can in fact occur
during any trimester as well. Some
women may experience a mild to
moderate flare during or after their
pregnancy; others may not. Pregnant
women with lupus, especially those
taking corticosteroids, are also
likely to develop pregnancy-induced
hypertension, diabetes, hyperglycemia,
and kidney complications. About 25
percent of babies of women with lupus
are born prematurely, but do not suffer
from birth defects. If a patient has
not been on glucocorticoids during
pregnancy, there is no reason to
initiate these medications to prevent a
postpartum flare.
In rare cases, babies may be born with
a condition called neonatal lupus. This
condition causes the fetus or neonate
to develop problems in the heart, skin,
liver, and/or blood. Neonatal lupus is
not the same as SLE. It is associated
with maternal antibodies called anti-
Ro(SSA) and anti-La(SSB). Neonatal
lupus can be identified in utero between
18 and 24 weeks. The most common
manifestations are heart block (heart
beats abnormally slowly) or a rash, most
often seen around the eyes.

Potential Lupus Complications During Pregnancy
Lupus flare
- morning stiffness and swollen
joints
- fever
- development or worsening of
a rash
Miscarriage
- cramping
- vaginal bleeding (spotting to
heavy bleeding)
Pregnancy-induced
hypertension
- blood pressure 140/90 and
over during the second half of
pregnancy
- generalized edema
- proteinuria
Pre-eclampsia
- blood pressure 140/90 and
over during the second half of
pregnancy
- proteinuria
- epigastric pain
- hyperreflexia
- edema, including face and
hands
- headache
Eclampsia
- all of the symptoms of pre
eclampsia
- seizures
Neonatal lupus
- transient rash
- transient blood count
abnormalities
- heartblock

Potential Problems
1. lupus flare
2. increased risk of spontaneous
abortion or stillbirth
3. pregnancy-induced hypertension
4. increased risk of prematurity
5. neonatal lupus
Nursing Interventions
Objective: Educate the woman
regarding birth control options and
risks of pregnancy.
1. Encourage patient to plan
pregnancy during remission and
only after consulting with her
doctor.
2. Discuss birth control options:
- Barrier methods (diaphragm
or condom with spermicidal
foam) are the safest.
- Intrauterine devices (IUD)
should be considered for
people with lupus on a caseby-
case basis. Women on
immunosuppressive drugs
in particular may be at
increased risk of infections
from IUDs. Women with
thrombocytopenia may have
an increased risk of bleeding.
- Oral contraceptives may be
appropriate if there are no
APLs.
3. Discuss the potential risks of
pregnancy and the importance of
careful monitoring.
Objective: Ensure a healthy, full-term
pregnancy.
1. Urge patient to keep
appointments with her primary
doctor and obstetrician.
2. Instruct patient to observe for
signs of complications or an
impending flare.
3. Monitor blood pressure and
watch for signs of toxemia,
which may be hard to
distinguish from a lupus kidney
flare.

Information Sheet on Pregnancy and
Lupus.
