BACKGROUND Pancreatic adenocarcinoma (PAC) is an aggressive cancer with a poor prognosis. To date, PAC causes are still largely unknown. Antigens and replicative sequences of oncogenic hepatitis B (HBV) and hepatitis C (HCV) virus were detected in different extra-hepatic tissues, including pancreas. OBJECTIVE a systematic review and meta-analysis of(More)
Immunohistochemistry provides an important indicator for differential diagnosis between pleural malignant mesothelioma and lung adenocarcinoma, which have complex therapeutic and medicolegal implications. To pinpoint a reliable, restricted panel of markers, the authors evaluated the efficacy of select commercial antibodies in a series of patients with(More)
A subset of patients with idiopathic chronic urticaria (CU) has been recently classified as autoimmune on the basis of two main findings: association with thyroid autoimmunity and with anti-IgE and/or anti-IgE receptor antibodies. The association of CU with thyroid autoimmunity has been known since 1983, but its frequency varies in different reports. The(More)
OBJECTIVE To test the reliability of a new enzyme-linked immunosorbent assay (ELISA) to identify anti-RNA polymerase III (RNAP III) positive sera from Italian patients with Systemic Sclerosis (SSc) and other chronic inflammatory disorders. METHODS A comparison between the new ELISA for anti-RNAP III and the gold standard technique, immunoprecipitation(More)
Cytokeratin (CK) patterns and albumin messenger RNA (mRNA) are investigated in 24 patients with benign hepatic lesions (7 patients with focal nodular hyperplasia [FNH], 10 with hepatocellular adenomas [HA], 1 with biliary hamartoma, 4 with biliary cysts, 2 with cystadenomas) and in 8 patients with cystadenocarcinoma, a rare liver malignancy. The lesions and(More)
Pancreatic adenocarcinoma (PAC) is a very aggressive and lethal cancer, with a very poor prognosis, because of absence of early symptoms, advanced stage at presentation, early metastatic dissemination and lack of both specific tests to detect its growth in the initial phases and effective systemic therapies. To date, the causes of PAC still remain largely(More)
BACKGROUND The detection of diagnostic autoantibodies such as antinuclear antibodies (ANA), anti-smooth muscle antibodies (SMA), anti-liver/kidney microsomal type 1 (anti-LKM1), anti-liver cytosol type 1 (anti-LC1) and anti-soluble liver antigen (anti-SLA) is historically associated with the diagnosis of autoimmune hepatitis. KEY MESSAGES When autoimmune(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)
CONTEXT Hepatitis B (HBV) and hepatitis C virus (HCV) possess well-known oncogenic properties and may promote carcinogenesis in liver. However antigens and replicative sequences of HBV/HCV have been also detected in different extra-hepatic tissues, including the pancreas. Although epidemiological studies and meta-analyses have recently suggested that(More)
