摘要

Background

Current therapeutic interventions for Sickle Cell Disease (SCD) have improved patient survival; however, the clinical determinants of elevated autoantibody prevalence and related complications in patients with SCD remain insufficiently elucidated.

Objective

This study aimed to examine the frequency of lupus anticoagulant (LA), anticardiolipin antibody (aCL), and anti-beta2 glycoprotein I antibodies (anti- β2GPI) in patients with SCD at steady state phase to evaluate their possible correlations with hematological factors and clinical complications.

Methods

This cross-sectional study involving 92 SCD patients in a steady state phase was conducted. Blood specimens were obtained for complete blood count (CBC), in conjunction with the identification of IgG for aCL and anti-β2GPI utilizing enzyme-linked immunosorbent assay (ELISA) and the assessment of LA through the Diluted Russell Viper Venom Time (dRVVT).

Results

The prevalence of LA, aCL, and anti-β2GPI (IgG) in SCD patients at steady state was 29.4%, 16.3%, and 5.4%, respectively. A correlation was found between LA and chronic leg ulcers, history of thrombosis, decreased platelet counts (PLT), and increased mean platelet volume (MPV) in SCD patients. Furthermore, aCL (IgG) exhibited a significant association with chronic leg ulcers, history of thrombosis, elevated Hemoglobin (Hb) levels, increased red blood cell count (RBC), and higher red cell distribution width (RDW) in SCD patients at steady state phase.

Conclusion

This research elucidates the incidence of LA and aCL in SCD patients during steady state, linking these autoantibodies to hematological parameters and clinical complications; thus, prospective assessments of aPL in SCD patients are essential.
