While lupus can have profound effects on both mother and child during pregnancy, most women seem to affect the long-term course of their lupus. It is very imporant to remember that later pregnancies may affect lupus differently in the same patient. These appears to be an increased risk of lupus flares during pregnancy, especially during the days surrounding childbirth. There is also an increased risk of miscarriage in patientgs with lupus. The miscarriages associated with lupus often occur in the third and fourth months of pregnancy and may not necesasrily have any relationship t ohow mild or severe the mother's othre symptoms are at that time. Currently research into possible causes for recurrent miscarriages is focusing on the lupus anticoagulant and the anti-cardiolipin antibody. Such antibodies are fond in the blood of approximately fifteen percent of patients with lupus. It appears that therapy with prednisone, aspirin, heparin, or gamma globulin either alone or used togehter may help reduce the number of miscarriages in these patients.

Pregnant patients with lupus may have an increased chance for a premature delivery. This is due both to spontaneous premature labor and to emergency Ceasarean section. The caesarean sction is done if the mother's condition is deteriorating or the baby is in jeopardy. Patients with lupus may also have an increase in the possibility of having a stillborn child. This is especially true in patients who have severe kidney involvement.

Infants born to mothers with lupus may have rashes on their face, scalp, and chest. These rashes usually disappear by one year of age. Once in a great while, these babies may develop a congential heart block. In these cases, the baby's heart beats at a slower rate than normal before birth, or continus to do so after delivery. This disorder is associated with the presence of the anti-RO (SS-A) antibody in mothers with lupus. If this problem is recognized early, however, most of these babies will do well after birth.

Most patients with lupus can have a successful pregnancy. There are certain factors that must be watched and there are certain measures the pregnant patient herself can take to help assure that she has a healthy baby. Most importantly, a patient's lupus should be in clinical remission before conception. If possible she should try to wait six months after her last flare of lupus before conceiving. If her condition is stable, the patient should have blood tests performed for the presence of the anti-RO antibody, the lupus anticoagulant, and the anti-cardiolipin antibody. If the anti-RO antibody is present, the patient should be watched closely for the possible development of fetal heart block. If the lupus anticoagulant or anti-cardiolipin antibody is present, the patient should probably receive steroid therapy throughout her pregnancy.

The obstetrician and rheumatologist must work together as a team to help the patient throughout her pregnancy. The patient's blood pressure should be checked frequently. Her kidney function should be checked monthly. Ultrasound exams should be used frequently during pregnancy in a patient with lupus to make certain that the fetus is growing properly. Ultrasound is a technique which uses high frequency sound waves to photograph the fetus. This test is painless and safe. Another safe test involves use a fetal heart rate monitor to observe the patterns of the fetal heart rate for 20-40 minutes, in the last months of pregnancy, this test may be performed to make certain that there are no flares of the lupus. Although having blood test watch the level of certain antibodies in the blood during late pregnancy to be assured that the mother's condition is stable.

Upon learning that they are pregnant, many women react by immediately stopping all medications. This should not be done without consulting both the obstetrician and rheumatologist. Steroids are the mainstay of treating lupus, and they and they and most medications used to treat lupus cause no serious problems for the fetus.

Patients should choose a obstetrician who is familiar with lupus and who feels comfortable treating pregnant patients with this illness.
