ADVERSE pregnancy outcomes rise markedly following systemic lupus erythematosus diagnosis, demanding specialized reproductive care. Investigations presented at ACR Convergence 2026, the annual meeting of the American College of Rheumatology, illuminate critical clinical intersections between maternal autoimmune disease activity, perinatal complications, and novel digital counseling tools.
A multicenter investigation evaluated 2,067 pregnancies across 849 women to quantify maternal and fetal complications occurring before, during, and after systemic lupus erythematosus diagnosis. Researchers observed that adverse pregnancy events escalated sharply following disease onset. Extreme preterm delivery rates increased from 2.0% in pre-diagnosis gestations to 7.5% peri-diagnosis and 9.0% post-diagnosis. Late preterm births similarly rose from 11.7% to 27.5% and 31.8%, while preterm preeclampsia climbed from 1.5% prior to onset to approximately 11% in subsequent pregnancies.
After adjusting for demographic factors, pregnancies occurring around or after diagnosis exhibited a two to five fold higher risk of adverse outcomes compared with gestations established over two years before onset. Maternal risk proved especially pronounced among individuals presenting with active lupus nephritis or positive lupus anticoagulant serologies. Clinicians emphasize that therapeutic research must actively include pregnant cohorts to formulate targeted management strategies that safeguard both maternal and neonatal health.
As patients increasingly seek clinical guidance online, a companion study assessed four large language models addressing family planning, gestation, and lactation in inflammatory rheumatic diseases. Ten expert rheumatologists evaluated fifty-four standardized clinical prompts across safety, completeness, and relevance criteria. While all models demonstrated acceptable clinical safety, significant performance discrepancies emerged regarding content completeness and nuance.
Specialists emphasized that algorithmic tools require extensive refinement and cannot substitute for individualized medical judgment. Collaborative reproductive management combining specialist vigilance with validated patient education remains vital to optimize perinatal outcomes across complex autoimmune populations.
