title: [Clinical features and adverse pregnancy outcomes of new onset systemic lupus erythematosus during pregnancy].
abstract: Objective:To investigate the clinical characteristics and adverse pregnancy outcomes in pregnant women with new onset systemic lupus erythematosus (SLE) during pregnancy.Methods:The clinical data of 263 pregnancies with SLE in the First Affiliated Hospital of Zhongshan University from 2001 to 2015 were collected and analyzed retrospectively.Results:Of all the 263 pregnancies, 188 were diagnosed before pregnancy and 75 were newly diagnosed during pregnancy. Among the 75 new onset SLE, 27, 31, 14 and 3 cases were diagnosed during first trimester, second trimester, third trimester and puerperium, respectively. Active lupus was noted in 81.3% of the patients with new onset SLE. The main clinical manifestations of new onset SLE were lupus nephritis (57.3%) and thrombocytopenia (38.7%). SLEPDAI scores as well as the prevalence of lupus nephritis, and thrombocytopenia in patients with new onset SLE was higher than those in the previously diagnosed ones (P<0.05). Among the 75 new onset SLE pregnancies, adverse pregnancy outcomesoccurred in 53 patients, including 34 with pregnancy loss, 15with premature, 8with intrauterine growth restriction, 5with fetal distress and5 with neonatal lupus. Compared with patients withnon-newonset SLE, patients with newonset SLEhad a higher prevalence of adverse pregnancy outcomes (56.4% vs 70.7%,P<0.05), and pregnancy loss (21.8% vs 45.3%,P<0.01) but less live birth (78.2% vs 54.7%,P<0.05).Conclusion:Most of the patients with new onset SLE occurred during the first and second trimester. The most common clinical features of new onset SLE were lupus nephritis and thrombocytopenia. Patients with new onset SLE were more prone to active lupus, lupus nephritis and thrombocytopenia, as well as more adverse pregnancy outcomes and pregnancy loss.
