Detection of Annexin A2 in Systemic Lupus Erythematosus

Systemic Lupus Erythematosus (SLE)Lupus Nephritis

There is substantial clinical and biological intra and inter-patient variability in SLE. Vascular, renal and neurologic deficiency can be organ-threatening or even life-threatening, leading to increased morbidity and mortality. Thus, biomarkers of disease activity and prognosis are required for regular follow-up of SLE patients. Implication of Toll-like Receptors (TLRs) in SLE has been extensively studied in mice models and humans. Self nuclear antigens bind to TLRs which are located on the surface of dendritic cells, B-cells, and endothelial cells, leading to production of pro-inflammatory cytokines and pathologic autoantibodies involved in organ dysfunction of SLE patients. Moreover, TLR expression in SLE is significantly higher and significantly correlated with disease activity. Annexin A2 (ANXA2) is a member of the annexins superfamily which exists as a monomer or heterotetramer and is implicated in several biological processes. Most notably, it binds to ẞ2GP1/anti-ẞ2GP1 antibodies and mediates endothelial cell activation via a TLR4 signaling pathway, highlighting its key role in Antiphospholipid Syndrome (APS) frequently associated with SLE. ANXA2 is also involved in the physiopathology of SLE. Anti-DNA autoantibodies can bind with ANXA2 expressed on mesangial cells in lupus nephritis. Besides, a french study carried out in Amiens' University Hospital showed that vascular lesions in lupus nephritis were associated with a significant increase in vascular expression of ANXA2.

Anti-ficolin-2 Autoantibodies in Lupus Nephritis

Lupus ErythematosusSystemic

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease characterized by the production of multiple autoantibodies. The prevalence and significance of antibodies against Ficolin-2 have not been yet investigated. The aims of this study were to determine the prevalence of anti-ficolin-2 antibodies among SLE patients and to investigate their potential as diagnostic and/or prognostic biomarkers in SLE. This study is a secondary phase of a serum sample analysis done in early 2015 in order to determine the prevalence of anti-ficolin-2 antibodies among the same cohort as the previously declared study (ClinicalTrials.gov ID: NCT02625831; Unique Protocol ID: 1841851v0). In this retrospective study, clinical data were obtained from medical files and blood samples were selected from preexisting biological collection. SLE patients (n=165) were informed and did not objected, they were matched to healthy controls (n=48). Disease activity was determined according to the SLEDAI score. Anti-ficolin-2 antibodies levels were measured in sera by ELISA and correlated to previously obtained Anti-ficolin-3, Anti-ficolin-2, anti-dsDNA and anti-C1q antibodies levels. The titer of anti-ficolin-2 antibodies was correlated with the SLEDAI score (p<0.0001). The presence of anti-ficolin-2 antibodies was associated with anti-ficolin-3 antibodies, anti-C1q and anti-dsDNA antibodies. Interestingly, the combination of anti-ficolin-3, anti-ficolin-2 and anti-C1q antibodies demonstrated higher specificity than any other traditional biomarker. These results suggest that anti-ficolin-3 and anti-ficolin-2 antibodies could be useful for the diagnosis of active nephritis in SLE patients.

Anti-ficolin-3 Autoantibodies in Lupus Nephritis

Lupus ErythematosusSystemic

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease characterized by the production of multiple autoantibodies. Antibodies against Ficolin-3 were previously identified in the sera of some SLE patients, but their prevalence and significance have not been yet investigated. The aims of this study were to determine the prevalence of anti-ficolin-3 antibodies among SLE patients and to investigate their potential as diagnostic and/or prognostic biomarkers in SLE. In this retrospective study, clinical data were obtained from medical files and blood samples were selected from preexisting biological collection. SLE patients (n=165) were informed and did not objected, they were matched to healthy controls (n=48). Disease activity was determined according to the SLEDAI score. Anti-ficolin-3, anti-dsDNA and anti-C1q antibodies levels were measured in sera by ELISA. First, a highly significant difference was found in the anti-ficolin-3 levels between SLE patients and healthy subjects. Anti-ficolin-3 antibodies were detected as positive in 58 of 165 (35%) SLE patients. The titer of anti-ficolin-3 antibodies was correlated with the SLEDAI score (p<0.0001). The presence of anti-ficolin-3 antibodies was associated with anti-C1q and anti-dsDNA antibodies. Regarding associations with clinical manifestations, only the presence of active lupus nephritis was significantly associated with the presence of anti-ficolin-3 antibodies (p=0.0001). This association with renal involvement was higher with anti-ficolin-3 antibodies than with other auto-antibodies. Interestingly, the combination of anti-ficolin-3 and anti-C1q antibodies demonstrated higher specificity than any other traditional biomarker. These results suggest that anti-ficolin-3 could be useful for the diagnosis of active nephritis in SLE patients.

Anti-ficolin-3 Antibodies in Lupus Nephritis

Systemic Lupus Erythematosus Nephritis

Systemic lupus erythematosus (SLE) is a chronic autoimmune disease characterized by the production of multiple autoantibodies and accumulation of immune complexes resulting in systemic inflammatory response and tissue damage. Although the underlying mechanisms are complex, defects in dying cells elimination are likely to contribute to autoantigen overload and development of autoimmunity. Molecules important in damaged cell clearance, such as early complement components, may thus have a protective role. According to this hypothesis, deficiencies in C1q and MBL, the recognition proteins of the classical and lectin pathways of complement; are associated with increased susceptibility to SLE. In the proposed project, the investigators will investigate the involvement of another related recognition protein, ficolin-3, which activates the complement lectin pathway and recognizes necrotic cells. The investigators have shown in a recent study a significant association between the presence of anti-ficolin-3 antibodies and active nephritis in patients with SLE. However, the possible involvement of anti-ficolin-3 antibodies in the pathogenesis of SLE and particularly in lupus nephritis (LN) remains to be elucidated. This project plans to investigate the role of ficolin-3 and ficolin-3 autoantibodies in LN. The study associates two aspects, aiming at deciphering the role of anti-ficolin-3 antibodies in dying cells recognition and investigating the role of ficolin-3 in renal tissue damage. This pilot study will be performed for 14 patients with active LN on serum and renal biopsy, realized for routine patient care. The investigators will explore the effect of anti-ficolin-3 antibodies purified from the patient serum on ficolin-3-dependent necrotic cells recognition, in relation with possible altered clearance of dead cells, which is an important hypothesis of the pathogenesis of SLE. The investigators will also investigate ficolin-3 deposition in renal biopsy, which may contribute to the local formation of immune complexes, leading to complement activation and subsequent inflammation and tissue injury.
