Serum MPO-DNA Complexes as a Biomarker of Disease Activity in Systemic Lupus Erythematosus
Serum Myeloperoxidase-DNA Complexes as a Novel Biomarker of Neutrophil Extracellular Trap and Disease Activity in Systemic Lupus Erythematosus
Systemic lupus erythematosus (SLE) is a chronic autoimmune disease characterized by immune system dysregulation and inflammation affecting multiple organs. A key mechanism in its development involves the excessive formation and impaired clearance of neutrophil extracellular traps (NETs), which release myeloperoxidase-DNA (MPO-DNA) complexes into the circulation. Although standard laboratory markers like complement proteins (C3, C4) and anti-dsDNA antibodies are routinely used, they often show inconsistent sensitivity in monitoring disease activity and flare-ups.
The primary purpose of this observational study is to evaluate serum MPO-DNA complexes as a circulating biomarker of NET formation in patients with systemic lupus erythematosus.
The study aims to:
- Measure serum MPO-DNA complex levels in active SLE patients compared to age- and sex-matched inactive SLE controls.
- Assess the correlation between MPO-DNA complex levels and clinical disease activity measured by the SLE Disease Activity Index 2000 (SLEDAI-2K) score.
- Evaluate the diagnostic accuracy of MPO-DNA complexes compared to conventional inflammatory and immunological markers (ESR, CRP, C3, C4, and anti-dsDNA).
Participants will undergo routine clinical assessments and standard blood sampling to measure routine laboratory parameters and circulating MPO-DNA complex levels via enzyme-linked immunosorbent assay (ELISA).

|
Active SLE Patients
Consists of 45 patients clinically diagnosed with systemic lupus erythematosus according to the 2019 EULAR/ACR classification criteria, presenting with active disease as determined by the Systemic Lupus Erythematosus Disease Activity Index 2000 (SLEDAI-2K).
Serum samples are collected to measure circulating myeloperoxidase-DNA (MPO-DNA) complexes via ELISA alongside routine inflammatory and immunological markers.
|
|
Inactive SLE Controls
Consists of 45 age- and sex-matched patients clinically diagnosed with systemic lupus erythematosus according to the 2019 EULAR/ACR classification criteria, presenting with inactive disease (clinical remission) based on SLEDAI-2K scoring.
Serum samples are collected to evaluate baseline circulating MPO-DNA complex levels and routine laboratory parameters for comparative analysis.
