Abstract

The aim was to study the feto-maternal outcome of pregnancies complicated by systemic lupus erythematosus (SLE). Analysis of a prospectively-maintained database of 73 patients (June 2006–March 2016) was done. Diagnosis of SLE was made by ACR(American College of Rheumatology)-criteria. Protocol scans and blood tests were done and patients with active disease were followed biweekly for 28 weeks, and weekly thereafter. Mean age + SD was 29 ± 4.9. SLE was diagnosed before conception in 86% of patients. A total of 33% had active disease status during pregnancy and out of them 58% had a flare of SLE, compared to 26% who were in remission (p = .008). SLE activity had no effect on the rate of foetal demise (p = .57). Overall pregnancy loss was 14% with no maternal mortality. The incidence of SLE flare during pregnancy was significantly higher in patients who had active disease. But the incidence of foetal demise was not affected by disease activity.

    Impact Statement

  • What is already known on this subject: SLE is one of the most common immunological disorders associated with pregnancy. Both SLE and pregnancy tend to influence each other due to complex interaction. The opinion seems to be divided regarding influence of pregnancy on SLE flare in world literature.

  • What the results of this study add: Our data suggests a significantly greater incidence of SLE flare during pregnancy in patients with active disease, than in those in remission.

  • What the implications are of these findings for clinical practice and/or further research: Though the majority of these flares were not major and did not require hospitalisation, these patients usually have a bad obstetric history. However, with multidisciplinary involvement, SLE activity in our series was not an independent predictor of a poor pregnancy outcome.
