Autoantibodies are frequently determined in unclear clinical situations and in the context of an inflammatory syndrome. The aim of this article is not to review all autoantibodies in details, but to discuss those used in clinical practice by describing their methods of detection and interpretation. Thus we will focus on antinuclear antibodies (ANA), which are typically associated with connective tissue diseases, as well as anti-neutrophil cytoplasmic antibodies (ANCA), which are useful in the diagnosis of ANCA-associated vasculitides. Due to its high sensitivity indirect immunofluorescence is used as a screening test; when positive, ELISA is performed to search for antibodies more specifically associated with certain auto-immune diseases.

Objective: To delineate, within the framework of current clinical practice and criteria, the sustainability of first-line immuno-suppressive treatment discontinuation in rheumatoid arthritis (RA) and the impact of residual disease in remission on long-term drug-free (DF) outcomes.
Methods: RA patients, referring to the Pavia early arthritis clinic (EAC) between 2009 and 2021 and achieving remission after Disease Activity Score-driven methotrexate (MTX) monotherapy, were recruited. Eligible patients underwent DF follow-up at 3-month intervals over 5 years after MTX discontinuation.

Introduction: Developing strategies to improve the therapeutic efficacy of mesenchymal stem cell (MSC)-derived extracellular vesicles (EVs) in autoimmune diseases have garnered increased attention.
Objectives: To evaluate whether rapamycin-induced autophagy within the systemic lupus erythematosus (SLE) inflammatory microenvironment (Rapa-SLE) augments the therapeutic effects of MSC-derived EVs in SLE.
Methods: The therapeutic potential of the resulting EVs (Rapa-SLE-EV) was assessed in MRL/lpr mice.

Background And Objectives: Cognitive deficits represent a major long-term complication of anti-leucine-rich, glioma-inactivated 1 encephalitis (LGI1-E). Although severely affecting patient outcomes, the structural brain changes underlying these deficits remain poorly understood. In this study, we hypothesized a link between white matter (WM) networks and cognitive outcomes in LGI1-E.

Objective: Type1Screen offers islet autoantibody testing to Australians with a family history of type 1 diabetes (T1D) with the dual aims of preventing diabetic ketoacidosis (DKA) and enabling use of disease-modifying therapy. We describe screening and monitoring outcomes 2 years after implementing in-home capillary blood spot sampling.
Research Design And Methods: Data from 2,064 participants who registered between July 2022 and June 2024 were analyzed: 1,507 and 557 chose blood spot and venipuncture screening respectively.
