The second trimester Doppler ultrasound examination is the best predictor of late pregnancy outcome in systemic lupus erythematosus and/or the antiphospholipid syndrome.

OBJECTIVE: To examine the predictive value of clinical examination, laboratory tests and Doppler ultrasound examination in systemic lupus erythematosus (SLE) and/or antiphospholipid syndrome (APS) pregnancies. METHODS: A prospective study of 116 pregnancies followed in a single tertiary referral centre. Outcomes analysed were fetal/neonatal death and adverse pregnancy outcome. Univariate analysis was performed for: (i) medical and obstetric history; (ii) medical and obstetric clinical examination; (iii) biological data; (iv) Doppler ultrasound examination. Variables significantly associated with the outcomes in the univariate analysis were entered into a logistic regression model. RESULTS: Sixteen out of 116 pregnancies ended in 12 fetal deaths and 4 embryonic losses. Hence, data for 100 pregnancies were analysed. Seven fetal deaths and one neonatal death occurred, associated with abnormal end-diastolic umbilical artery Doppler flow at the second trimester (P < 0.006), a history of thrombophlebitis (P < 0.001) or notched uterine artery and growth restriction at the second trimester (P < 0.002). Multivariate analysis retained abnormal end-diastolic umbilical artery Doppler flow (P = 0.047) and history of thrombophlebitis (P = 0.018) as significant predictors. Thirty-one adverse pregnancy outcomes occurred, associated with notched uterine artery (P < 0.00003), abnormal end-diastolic umbilical artery Doppler flow (P < 0.0006) and fetal growth restriction at the second trimester (P < 0.008), growth restriction (P < 0.00001) and notched uterine artery at the third trimester (P < 0.0008), use of heparin (P < 0.05) and history of thrombophlebitis (P < 0.04). Notched uterine artery at the second trimester remained the only predictor in multivariate analysis (P = 0.001). CONCLUSIONS: Results of the second trimester Doppler ultrasound examination are the best predictors for late pregnancy outcome in SLE and/or APS.

The HELLP syndrome in the antiphospholipid syndrome: retrospective study of 16 cases in 15 women.

OBJECTIVE: To study the characteristics of the haemolysis, elevated liver enzymes, low platelets (HELLP) syndrome in the antiphospholipid syndrome (APS) and its influence on the subsequent pregnancies. METHODS: This was a retrospective analysis of 16 episodes of HELLP complicating APS in 15 women. RESULTS: HELLP was complete in 10 cases and partial in six. It occurred during the second trimester in seven cases (the earliest at 18 weeks' gestation), the third trimester in seven cases, and the day following delivery in two cases. Pre-eclampsia was present in six cases and eclampsia in five. Outcome of pregnancies was: live birth (n = 8), stillbirth (n = 2) and fetal death (n = 6). APS was primary in nine women and secondary to systemic lupus erythematosus (SLE) in six. HELLP revealed primary APS in six cases. Seven women were not treated. Low dose aspirin was empirically prescribed in one woman whose APS had been undiagnosed despite a history of two fetal deaths. In the other women, therapy consisted of aspirin (n = 8), low molecular weight heparin with a dose varying between 3000 and 12 000 U daily (n = 5), and high dose immunoglobulin every 4 weeks (n = 2), hydroxychloroquine (n = 4), and prednisone (n = 6). Six women had seven subsequent pregnancies, 3-6 years after the complicated pregnancy. HELLP recurred at 33 weeks' gestation in one woman with SLE treated with prednisone, hydroxychloroquine, aspirin, and enoxaparin, and pregnancy ended in live birth. One woman became pregnant after in vitro fertilisation and embryo transfer, but pregnancy ended in fetal death despite prednisone, hydroxychloroquine, and enoxaparin. Four women had five uneventful pregnancies with 100 mg daily aspirin and heparin. CONCLUSIONS: APS may be revealed by HELLP. In APS, HELLP is associated with pre-eclampsia/eclampsia in most cases and seems to occur earlier than in the general population. Heparin plus aspirin may prevent obstetric complications in the subsequent pregnancies.
