AIM To assess the predictive value for chronic autoimmune gastritis (AIG) of the combined assay of anti-parietal-cell antibodies (PCA), anti-intrinsic-factor antibodies (IFA), anti-Helicobacter pylori (Hp) antibodies, and measurement of blood gastrin. METHODS We studied 181 consecutive patients with anemia, due to iron deficiency resistant to oral(More)
BACKGROUND Measurement of antibodies to citrullinated peptides or proteins (CP) is a new test for the diagnosis of rheumatoid arthritis (RA). We analyzed the analytical characteristics and diagnostic accuracy of commercially available methods. METHODS We studied 11 commercially available 2nd- and 3rd-generation methods that used various citrullinated(More)
BACKGROUND Assays for IgG antibodies against deamidated gliadin (IgG-anti-dGli) are comparable in performance with tests detecting IgA antibodies against tissue transglutaminase (IgA-anti-tTG) in diagnosing celiac disease (CD). IgA-anti-tTG are absent in IgA deficiency, a condition often associated with CD. In IgA deficiency, IgG-anti-tTG, which have a(More)
To the Editor: In a recent issue of this journal, van der Sluijs Veer and Vermes (1) reported a high prevalence and concentration of IgG anti-tissue trans-glutaminase (anti-tTG) antibodies in patients with systemic lupus ery-thematosus (SLE) and increased anti-dsDNA antibodies, as well as in anti-SSA/SSB-positive patients. No increase was observed in(More)
Il Gruppo di Studio in Autoimmunologia della SIPMeL ha riveduto e aggiornato le linee guida già proposte nel 2005 alla luce delle evidenze scientifiche comparse negli ultimi 10 anni per l’inquadramento diagnostico e il monitoraggio del paziente celiaco. L’identificazione della non celiac gluten sensitivity come entità nosologica a se stante ha reso inoltre(More)
Antidense fine speckles 70 (anti-DFS70) antibodies, a peculiar antinuclear antibody (ANA) pattern by indirect immunofluorescence, is frequently observed in ANA-positive individuals with no evidence of systemic autoimmune rheumatic disease. They may be found in many different inflammatory conditions and in healthy individuals. We herein report a case of an(More)
Rheumatoid arthritis (RA) is characterized by the presence of circulating rheumatoid factor (RF) and anticitrullinated peptide antibodies (ACPA), which are positive in about 70-80% of patients. APCA have a higher specificity and therefore a higher diagnostic power than RF, but are less informative than RF in monitoring the course of the disease in patients(More)
Il Gruppo di Studio in Autoimmunologia (GdS-AI) della Società Italiana di Patologia Clinica e Medicina di Laboratorio (SIPMeL), dopo 14 anni dalla ultima edizione, ha ritenuto opportuno revisionare e integrare le “linee guida per l’impiego di test per autoanticorpi nucleo-citoplasmatici nella diagnosi e nel monitoraggio delle malattie autoimmuni(More)
Primary biliary cirrhosis (PBC) is a chronic autoimmune cholestatic liver disease frequently characterized by anti-mitochondrial autoantibodies (AMA). A minority of patients are AMA-negative. Cytotoxic-T-Lymphocyte-Antigen-4 (CTLA-4) is a surface molecule expressed on activated T-cells delivering a critical negative immunoregulatory signal. A soluble form(More)
OBJECTIVE Identification of genetic biomarkers of response to biologics in rheumatoid arthritis (RA) is a relevant issue. The -174G>C interleukin-6 (IL-6) promoter polymorphism was investigated in RA patients treated with rituximab (RTX), being IL-6 a key cytokine for B cell survival and proliferation, thus possibly implicated in rituximab efficacy.
