To study the 5-year immunogenicity against a quadrivalent HPV vaccine in patients with SLE and healthy controls.

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.

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.

Patients with Systemic lupus erythematosus (SLE) are known to present an increased risk of osteoporosis and cardiovascular calcification. It has also been suggested that bone remodelling and cardiovascular calcification are regulated by the same mechanisms, but inversely in terms of calcium deposition, as osteoporosis is often associated with cardiovascular calcification. Inflammatory and immune factors have been implicated in these two processes. The role of the RANKL/OPG system in osteoclast differentiation has been elucidated over the last ten years. RANKL induces differentiation of monocytes-macrophages into osteoclasts, while, inversely, OPG exerts an inhibitory role by inactivating RANKL. Differentiation of smooth muscle cells into osteoblasts in the vessel wall induces calcification, and this phenomenon is counterbalanced by differentiation of monocytes into osteoclasts. Although the role of the RANKL/OPG ratio in the pathogenesis of osteoporosis has now been clearly established, its role in vascular calcification is only hypothetical at the present time. This study will focus on patients with SLE diagnosed and followed in the Amiens University Hospital Internal Medicine and Nephrology departments

This is a pilot study to assess the feasibility of using Surescripts refill data during the clinical encounter to improve medication adherence in patients with systemic lupus erythematosus

Several drugs and chemotherapies seem to have an impact on the immunological system. This study investigates reports of immunological toxicities, including the International classification of disease ICD-10 codes M05, M32, I78 for treatments in the World Health Organization (WHO) global Individual Case Safety Report (ICSR) database (VigiBase).

Demonstrate that custom-made insoles improve painful symptomatology, health and foot function in subjects with SLE and podiatric involvement.

Identification of biological markers able to better stratify cardiovascular risks in systemic lupus erythematosus patients is needed. We aimed to determine whether serum cardiac troponin T levels measured with a highly sensitive assay (HS-cTnT) may predict cardiovascular events in systemic lupus erythematosus.

Systemic Lupus Erythematosus (SLE) is a chronic autoimmune disease for which the aetiology includes genet-ic and environmental factors. It is rare in children as compared to adults. The severity may be related to greater involvement of genetic factors in children. The impact of genetics in the development of SLE is important, and the risk of recurrence in siblings evaluated by lambda S ratio is 30 in SLE, while it is 15 for type-1 diabetes and 8 rheumatoid arthritis, thereby indicating high impact of genetics in SLE. Recently, the group of Professor Yanick Crow in Manchester and other teams has identified new forms of lupus Mendelian genetics. The TREX1 and genes involved in the SAMHD1 frostbite lupus. Nearly 2 % of all adult subjects with SLE have a heterozygous mutation in the TREX1 gene, which therefore represents the first genetic cause of SLE. The team of Professor Crow also identified the ACP5 gene that is responsible for SLE associated with Spondylo-epiphyseal enchondro-epiphyseal dysplasia (syndromic lupus). Other groups have identified mutations in two genes encoding a DNAse (DNAse1 and DNAse1L3) responsible for familial monogenic forms of SLE. These new genes SLE were identified through research of germ-line mutations in cases of lupus syndromic or family. In collaboration with Professor Crow, we are currently undergoing characterization of a novel gene of SLE in a family and we have identified a second locus identified in another family. The identification of these genes provides a better understanding of the mechanisms regulating immune tolerance in humans. The frequency of these genetic forms is not known. There is very little data on the immunological phenotype of these patients. This is a clinical study to investigate the genetic and immunological abnormalities associated with pediatric SLE. The aim are to: study the genetics of pediatric SLE (or syndromic or family) and to search for mutations in the known genetic lupus or new genes in collaboration with Professor Yanick Crow. study the lymphocyte subpopulations and serum cytokines in pediatric patients with SLE (or syndromic or family) in the large Rhône- Alpes- Auvergne area.
