Description
Summary:Abstract Introduction Antivimentin/cardiolipin antibodies (aVim/CL) have emerged as potential diagnostic markers for antiphospholipid syndrome, However, their association with pregnancy outcomes remains unclear. This study explores the clinical significance of aVim/CL in pregnancy loss. Methods A retrospective analysis was conducted on 429 pregnant women with at least one spontaneous miscarriage at The Third Affiliated Hospital of Wenzhou Medical University (October 2019– August 2022). Multivariable logistic regression and stratified analyses were utilized to assess the relationship between aVim/CL levels and pregnancy loss. Results Among the 429 participants, 79 experienced pregnancy loss, while 350 had live births. Elevated aVim/CL levels were associated with an increased risk of pregnancy loss, with an odds ratio (OR) of 1.108 (95% CI, 1.037–1.185). The area under the ROC curve (AUC) was 62.8, with a sensitivity of 77.2% and a specificity of 44%. A nonlinear L-shaped relationship was identified, with a threshold of 6.86 ng/mL, below which the risk of pregnancy loss significantly increased. No correlations were found between aVim/CL and coagulation or immune biomarkers. Discussion Elevated aVim/CL levels were identified as independent predictors of pregnancy loss in women with a history of spontaneous miscarriage. The threshold of 6.86 ng/mL may provide valuable clinical insights for risk stratification.
