Lupus activity and pregnancy outcomes in systemic lupus erythematosus patients undergoing assisted reproductive therapy: A systematic review and meta-analysis.

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease primarily impacting women of childbearing age. While pregnancy and hormonal stress can trigger SLE flare-ups, the effects of assisted reproductive therapies (ARTs) on SLE patients are not well defined. We conducted a search of PubMed/Medline, Embase, and CENTRAL until March 20, 2024, to find observational studies assessing the prevalence of SLE flares and pregnancy outcomes following ARTs. Our analysis included random-effects meta-analysis and the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach for evaluating evidence quality. Five studies involving 237 SLE women who underwent ARTs were eligible. The meta-analysis indicated a prevalence of SLE flares at 17% (95% CI: 10–25%) with moderate-quality evidence. The pooled prevalence of arthritis flares was 7% (95% CI: 0–25%) with low-quality evidence. Successful pregnancy rates were 58% (95% CI: 43–72%), and live birth rates were 96% (95% CI: 83–100%), both with low-quality evidence. Moderate-quality evidence showed pregnancy complications, including preterm premature rupture of membranes (PPROM) at 8% (95% CI: 3–16%), miscarriages at 2% (95% CI: 0–9%), intrauterine fetal demise (IUFD) at 4% (95% CI: 0–11%), and preeclampsia at 7% (95% CI: 1–17%). Low-quality evidence showed preterm labor at 10% (95% CI: 0–32%) and ovarian hyperstimulation syndrome (OHSS) at 2% (95% CI: 0–11%). SLE flares, as well as pregnancy complications such as IUFD, miscarriage, PPROM, and preeclampsia in ART recipients, are equivalent to those in spontaneous conception. This indicates that ART is relatively safe for SLE patients with meticulous pregnancy planning. Key Points • Systemic lupus erythematosus (SLE) is a chronic autoimmune disease primarily impacting women of childbearing age. • Pregnancy in women with SLE poses elevated maternal and fetal risks compared to healthy women. • SLE flares and pregnancy complications while receiving ART are equivalent to those in spontaneous conception and ART is relatively safe for SLE patients.
