Dual MPO/PR3 ANCA positivity and vasculitis: insights from a 7-cases study and an AI-powered literature review.

Objectives: Anti-neutrophil cytoplasm antibodies (ANCA)-associated vasculitides (AAV) are rare conditions characterized by inflammatory cell infiltration in small blood vessels, leading to tissue necrosis. While most patients with AAV present antibodies against either myeloperoxidase (MPO) or proteinase 3 (PR3), rare cases of dual positivity for both antibodies (DP-ANCA) have been reported, and their impact on the clinical picture remains unclear. The goal of this study was to investigate the clinical implications, phenotypic profiles and outcomes of patients with DP-ANCA.

Abnormal B cell glycosylation in autoimmunity: A new potential treatment strategy.

Systemic lupus erythematosus (SLE) and primary Sjögren's syndrome (pSS) are two autoimmune diseases characterised by the production of pathogenic autoreactive antibodies. Their aetiology is poorly understood. Nevertheless, they have been shown to involve several factors, such as infections and epigenetic mechanisms.

Prescription of Physical Activity by General Practitioners in Type 2 Diabetes: Practice and Barriers in French Guiana.

Background: General practitioners (GPs) are the major primary healthcare players in the management of type 2 diabetes. In addition to a well-balanced diet, physical activity (PA) appears as a necessary non-medicinal therapy in the management of diabetic patients. However, GPs emphasize several obstacles to its prescription.

Metabolic Program of Regulatory B Lymphocytes and Influence in the Control of Malignant and Autoimmune Situations.

Metabolic pathways have been studied for a while in eukaryotic cells. During glycolysis, glucose enters into the cells through the Glut1 transporter to be phosphorylated and metabolized generating ATP molecules. Immune cells can use additional pathways to adapt their energetic needs.
