Abstract

Objective: Few studies have examined peripartum maternal outcomes in systemic lupus erythematosus (SLE). Using a de-identified electronic health record (EHR) cohort of individuals with and without SLE, we compared rates of peripartum maternal outcomes including maternal infections, blood transfusions, hospital length of stay, and SLE flares.

Methods: We identified deliveries among individuals with SLE and individuals without autoimmune disease using a previously validated algorithm. Peripartum maternal infection was assessed up to 6 weeks postpartum. Using Chi-square and Mann-Whitney U tests, we compared peripartum outcomes in SLE and control deliveries. We performed mixed effects models to estimate the association of SLE case status with peripartum outcomes. We assessed for SLE flares up to 6 months postpartum using chart review of rheumatology notes and the 2009 revised SELENA Flare Index. We evaluated SLE medications prescribed during pregnancy and at time of delivery on peripartum outcomes.

Results: We identified 185 deliveries to 142 individuals with SLE and 468 deliveries to 241 control individuals without autoimmune diseases. Mean length of hospital stay was longer for individuals with SLE compared to controls (3.1 ± 2.0 vs. 2.4 ± 1.0 days, p < 0.001). In a mixed effects model, peripartum infection was significantly associated with SLE case status (OR = 6.18, 95 % CI 2.73 - 13.98, p < 0.01), Cesarean section (OR = 5.00, 95 % CI 2.16 - 11.57, p < 0.01), and age at delivery (OR = 0.92, 95 % CI 0.86 - 0.99, p = 0.03) after adjusting for race. Transfusion was also significantly associated with SLE case status (OR = 9.05, 95 % CI 3.24-25.32, p < 0.01) and Black race (OR = 6.64, 95 % CI 1.47 - 30.02, p = 0.01) after adjusting for Cesarean section and age at delivery. We observed a postpartum flare rate of 32 % among individuals with SLE with 13 % characterized as mild, 41 % moderate, and 46 % severe. Antimalarial use in the postpartum period was associated with lower flare rate (43 % vs. 63 %, p = 0.04).

Conclusions: Individuals with SLE have increased rates of blood transfusions, longer hospital stays, and more frequent infections compared to control individuals in the peripartum period. We observed a postpartum flare rate of 32 %, and antimalarial use was associated with lower flare rate. Our findings demonstrate that the peripartum period remains a high-risk time for individuals with SLE with an ongoing need for close monitoring.
