Abstract：Objective To retrospectively characterize clinical features of preterm infants born to mothers with systemic lupus erythematosus (SLE). Methods Clinical data of preterm infants born to mothers with SLE in Peking Union Medical College Hospital over a period of more than 10 years (2000-2012) and preterm babies born to mothers without SLE in the same hospital and during the same time period were collected. Preterm-associated complications in the two groups of babies were comparatively analyzed. Results During the time period studied, 128 women with SLE delivered a total of 134 babies, 86 at full-term and 42 at preterm. Of the 42 preterm infants, 4 were diagnosed with neonatal lupus syndrome. Neonatal infection was the most common complication in preterm infants born to SLE mothers, which occurred in 20 cases (47.62%), followed by small for gestational age (28.57%), neonatal respiratory distress syndrome (26.19%), congenital heart disease (14.29%), and neonatal pulmonary hemorrhage (4.76%). In the same time period, 2 308 preterm babies were born to mothers without SLE. In these preemies, 16.81% experienced neonatal infection, 13.21% were small for gestational age, and 5.16% had congenital heart disease. All these parameters were significantly lower than in preterm babies born to mothers with SLE (P<0.05). Conclusions SLE preterm offspring seem to be more prone to neonatal infection, small for gestational age and at a higher risk of congenital heart disease as compared to preterm babies from women without SLE.
