A systematic review and meta-analysis of the association between the D-dimer and rheumatic diseases.

Overall, patients with RDs have significantly higher d-dimer concentrations when compared with healthy controls, indicating a state of hypercoagulability. The alterations in d-dimer concentrations are mediated by age, specific RD and RD category, RD duration, and markers of anticoagulation and inflammation. Further research is warranted to investigate d-dimer concentrations across the spectrum of RDs and their utility in predicting and managing VTE in these patients (PROSPERO registration number: CRD42024517712).
