The aim of the study was to determine the fetal and neonatal outcomes of pregnancies conceived during the inactive phase of systemic lupus erythematosus (SLE). Fetal and neonatal outcomes in 75 pregnancies of 33 patients with SLE were analyzed. In 19 patients (57.6%) the SLE also had hematological autoimmune presentations prior to gestation, such as anemia, thrombopenia, garnulocytopenia, and antiphospholipid antibody and/or lupus anticoagulant (APA). Out of 75 pregnancies, 19 elective terminations were carried out because the disease was active or for non-medical reasons. The adverse fetal outcomes of those 56 pregnancies which occurred during the inactive phase were compared with those of the control patients. In SLE, the rates of spontaneous abortions (46.4%) and newborns with low (< 2500 gr) birthweight (36.7%) were found to increase roughly three times that of the controls and the perinatal fetal loss (16.7%) also increased significantly as compared with the control group (28.5 per thousand). APA noted at any time before pregnancy increased the low birthweight rate (75%) six fold and the perinatal loss (33.3%) more than ten fold but did not affect the rate of spontaneous abortions. Any kind of hemocytopenias without APA, noted before pregnancy did not worsen the fetal outcome in SLE. Neonatal lupus was diagnosed in 2 out of the 30 newborns. Our results suggest that among the hematologic manifestations of SLE presenting before pregnancy, APA can predict the high risks of low birthweight and perinatal fetal loss as opposed to hemocytopenias.
