BACKGROUND Increased expression of B cell activating factor (BAFF or B lymphocyte stimulator) may explain the B cell activation characteristic of primary Sjögren's syndrome (pSS). OBJECTIVES To evaluate the efficacy and safety of belimumab, targeting BAFF, in patients with pSS. METHODS Patients were included in this bi-centric prospective 1-year(More)
Primary Sjögren's syndrome (pSS) is a chronic autoimmune disease characterized by a lymphocytic exocrinopathy. However, patients often have evidence of systemic autoimmunity, and they are at markedly increased risk for the development of non- Hodgkin's lymphoma. Similar to other autoimmune disorders, a strong interferon (IFN) signature is present among(More)
Primary Sjögren Syndrome (pSS) is an autoimmune disease associated with an increased risk of lymphoma. Lymphomas complicating pSS are mostly low-grade B cell non-Hodgkin lymphomas, predominantly of marginal zone histological type. Mucosal localization is predominant, notably mucosa-associated lymphoid tissue lymphomas. Lymphomas often develop in organs(More)
OBJECTIVE Non-Hodgkin's lymphoma (NHL) is a severe complication of primary Sjögren's syndrome (SS). Ectopic germinal centers (GCs) in the salivary glands are predictors of the occurrence of NHL. Given the association between CCL11 and CXCL13 and ectopic GCs, we assessed the link between these chemokines and NHL, as well as the association between these(More)
Rheumatoid arthritis (RA) is the most common chronic inflammatory rheumatic condition over the world. RA is potentially disabling because chronic inflammation of the joints leads to joint destruction. To date, the best predictor of radiographic progression for patients with early RA is the presence of radiographic erosions at baseline, but a limited number(More)
BACKGROUND Beyond genetics, epigenetics alterations and especially those related to DNA methylation, play key roles in the pathogenesis of autoimmune diseases such as primary Sjögren's syndrome (pSS) and systemic lupus erythematosus. This study aimed to assess the role of methylation deregulation in pSS pathogeny through a genome-wide methylation approach.(More)
OBJECTIVES To analyze the clinical and immunological characteristics at enrollment in a large prospective cohort of patients with primary Sjögren's syndrome (pSS) and to investigate the association between serum BAFF, beta2-microglobulin and free light chains of immunoglobulins and systemic disease activity at enrollment. METHODS Three hundred and ninety(More)
Several autoimmune diseases, including primary Sjögren's syndrome (pSS), are associated with an increased risk for lymphoma. Polymorphisms of TNFAIP3, which encodes the A20 protein that plays a key role in controlling nuclear factor κB activation, have been associated with several autoimmune diseases. Somatic mutations of TNFAIP3 have been observed in the(More)
OBJECTIVE To assess the link between monoclonal gammopathy (MG), disease activity, and incidence of malignant hematologic disorders (MHDs), including lymphoma and multiple myeloma (MM), in patients with primary Sjögren's syndrome (SS). METHODS Screening for the presence of MG was performed in 352 primary SS patients. Each patient with MG was paired with 2(More)
