Management of the High-Risk Lupus Pregnant Patient

Pregnancy in the lupus patient presents a unique clinical challenge. Pregnancy may interact with lupus nephritis and adds preeclampsia to the differential diagnosis of hypertension. Lupus may result in pregnancy loss, fetal growth restriction, and prematurity. The obstetric management of these complex issues is presented for the nonobstetrician.

Initial assessment

The initial assessment must always be a collaborative effort between the obstetrician and the rheumatologist. This must include a comprehensive and up-to-date assessment of the activity of lupus, organ damage, laboratory tests, and medication exposure.

The initial history should include the duration and current activity of the patient's disease. If she is in remission, how long the remission has lasted should be documented. Typical signs or symptoms the patient is known to experience during

Maternal health

Interactions between SLE and pregnancy include the overall activity of lupus and pregnancy outcome, the effect of lupus nephritis on pregnancy, the effect of pregnancy on the progression of lupus nephritis, and the differentiation of hypertension related to lupus nephritis from preeclampsia. The issue of lupus flares and pregnancy will be covered elsewhere in this issue.

Pregnancy loss

Pregnancy loss in patients with SLE is decreased if the patient has been in remission for 6 to 12 months before conception [1]. Patients with SLE experience pregnancy loss at a greater rate than the general population [3], [19], [20]. They experience a 4.7-fold increase in spontaneous abortion after the diagnosis of SLE compared with their reproductive history before the SLE diagnosis [21].

The gestational age at which pregnancy loss occurs in patients with SLE is difficult to determine, because

General

Prenatal care for patients with SLE begins with the standard prenatal care recommended jointly by the American Academy of Pediatrics and the American College of Obstetricians and Gynecologists [28]. This standard care should be modified for SLE patients because of their increased risks of pregnancy loss, intrauterine growth restriction, and preeclampsia. Additionally, collaborative monitoring of lupus activity between the rheumatologist and the obstetrician must be included. This part of the

Summary

A pregnancy in a patient with SLE is at high risk for maternal complications of pregnancy and pregnancy wastage. However, most patients can achieve a live birth. This can be achieved by close coordination of care between the patient's rheumatologist, obstetrician, and, in the case of renal involvement, her nephrologist.

      The 2016 WHO Antenatal Care guideline recommends that the general pregnant population have the first antenatal care contacts at 12 gestational weeks, followed by every 4 weeks from 20 to 34 weeks and then biweekly till 40 weeks [36]. For pregnant SLE patients, previous reports suggest obstetric visits every 4 weeks until 20 gestational weeks, followed by visits every 2 weeks afterwards until 28 weeks, and then, weekly until delivery, because preeclampsia occurs after 20 weeks [12]. We observed a trend toward greater prevalence of stillbirths due to placenta-mediated pregnancy complications in mothers with SLE compared with controls (44% [95% CI 14, 79] versus 15% [95% CI 6, 28]); this constituted the most frequent cause of stillbirth in the SLE group.

      APS is a predictor of adverse pregnancy complications in pregnant women with SLE, most notably predicting a high risk of second- and third-trimester losses and stillbirths [159,160]. In women with active SLE who are maintained on hydroxychloroquine, there is a consensus to continue treatment during pregnancy [161]. Although hydroxychloroquine crosses the placenta, it has been used safely in pregnancy with no reported foetal toxicity [162,163].
