Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
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.
