To evaluate the utility of neutrophil to lymphocyte ratio (NLR), systemic immune-inflammation index (SII), and systemic immune-response index (SIRI) in the prediction of adverse pregnancy outcomes in pregnant women with systemic lupus erythematosus (SLE). This retrospective case-control study was conducted in Ankara City Hospital perinatology clinic between 2019 and 2023. First-trimester NLR, SII (NLR X platelet count), and SIRI (NLR X monocyte count) values were compared between pregnant women with SLE (n = 29) and low-risk controls (n = 110). Afterward, pregnant women with SLE were divided into two groups: 1) SLE with perinatal complications (n = 15) and 2) SLE without perinatal complications (n = 14). NLR, SII, and SIRI values were compared between the two subgroups. Finally, a ROC analysis was performed to determine optimal cut-off values for NLR, SII, and SIRI in the prediction of composite adverse pregnancy outcomes. The study group had significantly higher first-trimester NLR, SII, and SIRI values compared to the controls. The SLE with perinatal complications group had significantly higher NLR, SII, and SIRI values than the SLE group without perinatal complications (p
