antiphospholipid antibody syndrome

Autoimmunità

Il Laboratorio di Autoimmunità si occupa di studiare i meccanismi patogenetici delle malattie autoimmuni, con particolare attenzione alla Sindrome da Anticorpi Antifosfolipidi, al Lupus Eritematoso Sistemico e all'Artrite Reumatoide. In particolare, precedenti ricerche in questo campo hanno analizzato le vie di trasduzione del segnale che agiscono attraverso i lipid rafts coinvolti nella patogenesi della Sindrome da Anticorpi Antifosfolipidi chiarendo il ruolo dell'apoptosi e/o dell'autofagia nelle risposte autoimmuni.

In vitro fertilization and autoimmunity. Evidence from an observational study

Introduction: : The aim of this study was to evaluate the prevalence of antiphospholipid antibodies (aPLs) in infertile women undergoing in vitro fertilization (IVF). Method of study: : From January 2012 to December 2017, 520 consecutive clinical records of infertile women undergoing IVF were evaluated. Among them, 100 consecutive clinical records of patients with positive autoantibodies were selected. Results: : In 100/520 (19.23%) women, positive auto-antibodies were detected: 35/520 (6.73%) fulfilled classification criteria for a systemic disease.

Post-translational modifications of proteins in antiphospholipid antibody syndrome

Antiphospholipid antibody syndrome (APS) is a systemic autoimmune disease characterized by arterial and venous thrombosis and/or pregnancy morbidity. The incidence is around five new cases/100,000 persons per year and the prevalence is around 40-50 cases/100,000. The prevalence is higher (about 30%) among patients with systemic lupus erythematosus. APS is associated with circulating antiphospholipid antibodies (aPLs), a heterogeneous group of autoantibodies directed against negatively charged molecules and a combination of protein-complexed phospholipids.
