Acute on chronic liver failure (ACLF) is a recently recognized syndrome and its definition has been evolving over last two decades. Currently, there is no universal consensus about the definition as kind of cases being seen in the Western world appear to be somewhat different from those that are seen in Asia Pacific region. But every one agrees that definition of ACLF should include following components. (a) The status of pre-existing liver disease, (b) defining the acute insult that leads to rapid deterioration of liver status, (c) time frame during which the acute insult can lead to rapid deterioration, (d) the quantification and definition of liver failure status after deterioration, which will determine the severity of ACLF, and (e) prediction of prognosis after analyzing first four components in the short and long terms...

Soluble fibrinogen-like protein 2 (sFGL2) is the soluble form of fibrinogen-like protein 2 belonging to the fibrinogen-related protein superfamily. It is now well characterized that sFGL2 is mainly secreted by regulatory T cell (Treg) populations, and exerts potently immunosuppressive activities. By repressing not only the differentiation and proliferation of T cells but also the maturation of dendritic cells (DCs), sFGL2 acts largely as an immunosuppressant. Moreover, sFGL2 also induces apoptosis of B cells, tubular epithelial cells (TECs), sinusoidal endothelial cells (SECs), and hepatocytes...

Extrahepatic manifestations of hepatitis C virus infection (HCV) are very common. The most common of these is mixed cryoglobulinaemia. Anti-HCV antibodies and viral ribonucleic acid, HCV RNA, can be found in the cryoprecipitates, together with the rheumatoid factor. Cryoglobulins consist of a complex of immunoglobulins that in vitro precipitate upon the cooling bellow the human body temperature. Vasculitis is caused by the deposition of such immune complexes in the small blood vessels. A link with the HCV infection is considered to be established with membranoproliferative glomerulonephritis, leukocytoclastic vasculitis, lymphoproliferative disorders (in particular B cell lymphoma), Sjögren and sicca syndrome, lichen planus, porfyria cutanea tarda and diabetes mellitus...

During the 25th annual meeting of the Asia-Pacific Association for the Study of the Liver (APASL 2016) in Tokyo, we organized and moderated an inaugural satellite symposium on the autoimmune liver diseases, autoimmune hepatitis (AIH) and primary biliary cholangitis (PBC). Following the keynote lecture by John M. Vierling (USA), speakers from the Asia-Pacific region provided an up-to-date perspective on the epidemiology, clinical practice and research in AIH and PBC in the Asia-Pacific region. Although epidemiology and clinical features of AIH seem to be similar in East Asia compared to those in western countries, the majority of patients with AIH are detected at an advanced stage and have higher mortality rates in South Asia, indicating an unmet need for earlier diagnosis and the initiation of appropriate immunosuppressive treatment...

BACKGROUND AND AIMS: The interplay between host anti-viral immunity and immunopathology during Hepatitis E virus (HEV) infection determines important clinical outcomes. We characterised the specificity, functionality and durability of host T-cell responses against the full-length HEV virus and assessed a novel "Quantiferon" assay for the rapid diagnosis of HEV infection. METHODS: 89 volunteers were recruited from Oxford, Truro (UK) and Toulouse (France) including 44 immune-competent patients with acute HEV infection, 18 HEV exposed immunosuppressed organ-transplant recipients (8 with chronic HEV), and 27 healthy volunteers...

There is substantial data that suggests an abnormality of innate immunity in patients with primary biliary cholangitis (PBC) which includes the transcription factor nuclear factor-kB (NF-kB) and well as downstream inflammatory signaling pathways. In addition, ImmunoChip analysis has identified a novel PBC-associated locus near the receptor activator of NF-kB ligand (RANKL) gene. Based on these observations, we investigated the role of the RANKL axis in the liver of patients with PBC compared to controls. We used immunohistochemistry to quantitate liver expression of RANKL, its receptor (RANK), and importantly the decoy receptor osteoprotegerin (OPG), including a total of 122 liver samples (PBC = 37, primary sclerosing cholangitis = 20, autoimmune hepatitis = 26, chronic hepatitis B = 32 and unaffected controls = 7)...

Macrophage activation is an important feature of primary biliary cholangitis (PBC) pathogenesis and other cholestatic liver diseases. Galectin-3 (Gal3), a pleiotropic lectin, is produced by monocytic cells and macrophages. However, its role in PBC has not been addressed. We hypothesized that Gal3 is a key to induce NOD-like receptor family, pyrin domain containing 3 (NLRP3) inflammasome in macrophages and in turn to propagate proinflammatory IL-17 signaling. In liver tissues from patients with PBC and dnTGF-βRII mice, a model of autoimmune cholangitis, the expression of Gal3, NLRP3, and the adaptor protein adaptor apoptosis-associated speck-like protein was induced, with the downstream activation of caspase-1 and IL-1β...

Autoimmune polyendocrinopathy-candidiasis-ectodermal dystrophy (APECED) is a rare primary immunodeficiency disorder typically caused by homozygous AIRE mutations. It classically presents with chronic mucocutaneous candidiasis and autoimmunity that primarily targets endocrine tissues; hypoparathyroidism and adrenal insufficiency are most common. Developing any two of these classic triad manifestations establishes the diagnosis. Although widely recognized in Europe, where nonendocrine autoimmune manifestations are uncommon, APECED is less defined in patients from the Western Hemisphere...

Patients receiving methotrexate (MTX) for the treatment of autoimmune disease are at a high risk of developing lymphoproliferative disorders (LPD), the so-called methotrexate-associated lymphoproliferative disorders (MTX-LPD). We recently performed abdominal ultrasonography (US) in a patient with rheumatoid arthritis (RA) who had developed hepatic dysfunction during the course of MTX therapy; the examination revealed multiple well-demarcated hepatic tumors with slightly irregular borders, the largest one measuring 9 cm in diameter...
