CD4 T lymphocyte autophagy is upregulated in the salivary glands of primary Sjögren’s syndrome patients and correlates with focus score and disease activity
Background Primary Sjögren’s syndrome (pSS) is a common chronic autoimmune disease characterized by lymphocytic infiltration of exocrine glands and peripheral lymphocyte perturbation. In the current study, we aimed to investigate the possible pathogenic implication of autophagy in T lymphocytes in patients with pSS. Methods Thirty consecutive pSS patients were recruited together with 20 patients affected by sicca syndrome and/or chronic sialoadenitis and 30 healthy controls. Disease activity and damage were evaluated according to SS disease activity index, EULAR SS disease activity index, and SS disease damage index. T lymphocytes were analyzed for the expression of autophagy-specific marke…
SAT0378 Autophagy is Up-Regulated in the Salivary Glands of Primary Sjogren's Syndrome Patients and Correlates with the Focus Score and Disease Activity
Background Autophagy is now considered as a major regulator in trafficking events that activates innate and adaptive immunity and consistent evidence supports its role in autoimmunity (1). Primary Sjogren9s syndrome (pSS) is a systemic autoimmune disease characterized by infiltration of exocrine glands by T and B cells that, producing chemokines and cytokines, coordinate the chronic inflammatory process. No data on the role of autophagy in pSS are available in humans, although studies in mice demonstrated its involvement in the salivary and lacrimal gland homeostasis (2,3). Objectives We investigated the autophagy process in salivary gland tissue and in peripheral T lymphocytes from pSS pat…
International consensus: What else can we do to improve diagnosis and therapeutic strategies in patients affected by autoimmune rheumatic diseases (rheumatoid arthritis, spondyloarthritides, systemic sclerosis, systemic lupus erythematosus, antiphospholipid syndrome and Sjogren's syndrome)?: The unmet needs and the clinical grey zone in autoimmune disease management
Autoimmune diseases are a complex set of diseases characterized by immune system activation and, although many progresses have been done in the last 15 years, several unmet needs in the management of these patients may be still identified. Recently, a panel of international Experts, divided in different working groups according to their clinical and scientific expertise, were asked to identify, debate and formulate a list of key unmet needs within the field of rheumatology, serving as a roadmap for research as well as support for clinicians. After a systematic review of the literature, the results and the discussions from each working group were summarised in different statements. Due to th…
