The expression or dysfunction of long non-coding RNAs (lncRNAs) is closely related to various hereditary diseases, autoimmune diseases, metabolic diseases and tumors. LncRNAs were also recently recognized as functional regulators of fibrosis, which is a secondary process in many of these diseases and a primary pathology in fibrosis diseases. We review the latest findings on lncRNAs in fibrosis diseases of the liver, myocardium, kidney, lung and peritoneum. We also discuss the potential of disease-related lncRNAs as therapeutic targets for the clinical treatment of human fibrosis diseases...

BACKGROUND: Conventional approaches to participant recruitment are often inadequate in rare disease investigation. Social networking sites such as Facebook may provide a vehicle to circumvent common research limitations and pitfalls. We report our preliminary experience with Facebook-based methodology for participant recruitment and participation into an ongoing study of autoimmune hepatitis (AIH). OBJECTIVE: The goal of our research was to conduct a pilot study to assess whether a Facebook-based methodology is capable of recruiting geographically widespread participants into AIH patient-oriented research and obtaining quality phenotypic data...

BACKGROUND: Patients with sickle cell disease (SCD) present a defective activation of the alternate complement pathway that increases the risk of infection and is thought to predispose to autoimmune disease (AID). However, coexisting AID and SCD is rarely reported, suggesting possible underdiagnosis due to an overlapping of the symptoms. STUDY DESIGN: Among 603 patients with SCD followed between 1999 and June 2016, we retrospectively searched for patients with coexisting SCD and AID...

AIMS: Methotrexate (MTX) is an efficient cytotoxic drug used against various carcinogenic, inflammatory and autoimmune diseases; however, the hepatotoxicity of MTX limits its use. Therefore, the present study aimed to evaluate the potential hepatoprotective and immune-stimulant effect of Spirulina platensis (SP) against MTX acute toxicity. MAIN METHODS: Thirty-two male Wistar rats were randomly allocated into the following four groups (n = 8): control, MTX (20 mg/kg bwt, single ip injection), SP (500 mg/kg bwt, oral gavage daily for 21 days), and MTX+SP...

Portal hypertension can lead to ectopic varices, which occur most frequently in the rectum. Rectal variceal bleeding in patients with portal hypertension is rare but can be life-threatening if not diagnosed and treated in a timely manner. However, no specific treatment guidelines have been established for rectal variceal bleeding. We herein report a case involving a woman with portal hypertension due to autoimmune liver disease who was successfully treated with a transjugular intrahepatic portosystemic stent shunt and variceal embolization...

Autoimmune hepatitis (AIH) is a progressive, chronic liver disease characterized by unresolving hepatocellular inflammation of autoimmune origin. The clinical spectrum may vary from asymptomatic presentation, to non-specific symptoms such as fatigue, arthralgias, nausea and abdominal pain, to acute severe liver disease. AIH is characterized by the presence of interface hepatitis and portal plasma cell infiltration on histological examination, hypergammaglobulinemia, and positive autoantibodies. AIH is associated with other autoimmune diseases and its course is often accompanied by various non-specific hematological disorders...

Immune checkpoint inhibitors (ICI) have dramatically changed the face of cancer treatment and are gaining in importance. The ICIs have now been approved for the treatment of advanced cancers, including melanoma, non-small-cell and small cell lung cancers, renal cell carcinoma, Hodgkin's lymphoma, head and neck cancers and urothelial carcinoma and further indications are to be expected. The organs most affected by an autoimmune reaction are the intestines, the musculoskeletal system, skin, endocrine organs, the liver and the lungs...

Autoimmune liver diseases (AILD) are chronic liver pathologies characterised by fibrosis and cirrhosis due to immune-mediated liver damage. In this study, we addressed the question whether mucosal-associated invariant T (MAIT) cells, innate-like T cells, are functionally altered in patients with AILD and whether MAIT cells can promote liver fibrosis through activation of hepatic stellate cells. We analysed the phenotype and function of MAIT cells from AILD patients and healthy controls by multi-colour flow cytometry and investigated the interaction between human MAIT cells and primary human hepatic stellate cells (hHSCs)...

Primary biliary cholangitis (PBC) is a chronic autoimmune cholestatic disease and may progress to liver fibrosis, liver cirrhosis, decompensated cirrhosis, and even end-stage liver disease without effective treatment. The diagnosis of PBC is mainly based on the biochemical parameters indicating cholestatic hepatitis and the presence of specific autoantibody in circulation. The goals of the treatment and management of PBC are to prevent the development of end-stage liver disease, to improve related clinical symptoms, and to improve patients' quality of life...

Primary biliary cholangitis (PBC) is an autoimmune liver disease mainly involving intrahepatic interlobular bile ducts and can progress to liver fibrosis, liver cirrhosis, and even liver failure. Ursodeoxycholic acid (UDCA) is the first-line therapeutic drug for PBC and can delay disease progression, but as high as 40% of patients have suboptimal response to UDCA. Obeticholic acid, a farnesoid X receptor agonist, has been approved by FDA in May 2016 for patients who have no response to UDCA treatment or cannot tolerate such treatment...

OBJECTIVES: Alcoholic liver disease and nonalcoholic fatty liver disease (NAFLD) are steatotic liver diseases and major causes of cirrhosis. Only a minority of patients with risk factors develop cirrhosis and genetic cofactors may be important in pathogenesis. Mutations in the Wilson's and α-1-antitrypsin genes are not uncommon and we speculated that they may act as cofactors. METHODS: We investigated α-1-antitrypsin phenotyes and caeruloplasmin levels in patients undergoing elective liver transplantation...

Although autoimmune hepatitis (AIH) can be treated with corticosteroid-based first-line therapy, incomplete remission is associated with progressive liver fibrosis. So far accepted predictors of the subsequent treatment response of AIH patients are lacking. Therefore, we analysed baseline parameters, including iron homeostasis and cytokine levels, in 60 children with paediatric AIH (pAIH). In contrast to adults, elevated serum markers indicating iron overload were not commonly found in children. Therefore, ferritin was not predictive of the treatment response in pAIH...

Assessing liver fibrosis is important for predicting the efficacy of antiviral therapy and patient prognosis. Liver biopsy is the gold standard for diagnosing liver fibrosis, despite its invasiveness and problematic diagnostic accuracy. Although noninvasive techniques to assess liver fibrosis are becoming important, reliable serum surrogate markers are not available. A glycoproteomics study aimed at identifying such markers discovered Mac 2-Binding Protein Gylcan Isomer (M2BPGi), which is a reliable marker for assessing liver fibrosis in patients with viral hepatitis and other fibrotic liver diseases such as primary biliary cholangitis, biliary atresia, autoimmune hepatitis, and nonalcoholic fatty liver disease...

BACKGROUND: Celiac disease (CD), a serious autoimmune disorder that occurs in people who are genetically predisposed, is induced by dietary gluten intake and affects primarily the small intestine. Many studies have identified an increased risk of cardiovascular problems in patients with CD. Moreover, these patients are susceptible to certain liver diseases, as well as fibrosis. OBJECTIVE: The aim of this study was to assess the presence of fibrosis using the De Ritis ratio, determining its effect on the electromechanical features of the left atrium and its susceptibility to atrial fibrillation (AF) in patients with CD...

Caspase-8 (CASP8) is known as an executioner of apoptosis, but more recent studies have shown that it participates in the regulation of necroptosis and innate immunity. In this study, we show that CASP8 negatively regulates retinoic acid-inducible gene I (RIG-I) signaling such that, in its absence, stimulation of the RIG-I pathway in dendritic cells (DCs) produced modestly enhanced activation of IFN regulatory factor 3 with correspondingly greater amounts of proinflammatory cytokines. In addition, mice lacking DC-specific CASP8 (dcCasp8-/- mice) develop age-dependent symptoms of autoimmune disease characterized by hyperactive DCs and T cells, spleen and liver immunopathology, and the appearance of Th1-polarized CD4+ T cells...

Dietary supplements known as "fat burners" are typically marketed with claims of increasing energy expenditure through alterations in fat metabolism. They are marketed as natural products and their use is thus perceived as a safe body weight reduction strategy. We report on five episodes of liver injury in four patients. Liver injury was associated with consumption of different commercially available fat burners: Green tea extract (Camellia sinensis), Garcinia gummi-gutta, green coffee beans, and spirulina (blue-green algae)...

Heat shock proteins (HSPs) play critical roles in the process of anti-stress and immunity and are implicated in autoimmune diseases. In order to understand the comparative stress responses of HSP60 and HSP90β under intermittent thermal stress and Aeromonas hydrophila infection, we cloned their full-length cDNAs from Megalobrama amblycephala liver, predicted their secondary and tertiary structure, and examined their tissue-specific expression patterns. The full length of HSP60 and HSP90β cDNAs indicated that they included all signature sequences of corresponding protein families...

Purpose: Celiac disease, an autoimmune enteropathy triggered by exposure to gluten, is not uncommon in South Jordan. However, its prevalence is underestimated due to lack of physician awareness of the diversity of disease presentation. The clinical spectrum includes classic gastrointestinal manifestations, as well as rickets, iron-deficiency anemia, short stature, elevated liver enzymes, and edema. Our goal was to evaluate celiac disease presentation in clinically diagnosed children. Methods: Retrospective study included all children diagnosed with celiac disease between September 2009 and September 2015...
