Inflammatory bowel disease (IBD) is a devastating disease that is associated with excessive inflammation in the intestinal tract in genetically susceptible individuals and potentially triggered by microbial dysbiosis. This illness markedly predisposes patients to thrombophilia and chronic debility as well as bowel, lymphatic, and liver cancers. Development of new therapies is needed to re-establish long-term immune tolerance in IBD patients without increasing the risk of opportunistic infections and cancer...

Hepatitis B is one of the most common infectious diseases globally. It has been estimated that there are 350 million chronic hepatitis B virus (HBV) carriers worldwide. The liver is connected to the small intestine by the bile duct, which carries bile formed in the liver to the intestine. Nearly all of the blood that leaves the stomach and intestines must pass through the liver. Human intestines contain a wide diversity of microbes, collectively termed the 'gut microbiota'. Gut microbiota play a significant role in host metabolic processes and host immune modulation, and influence host development and physiology (organ development)...

Programmed death-1 (PD-1) is involved in the immune dysfunction of hepatitis B virus (HBV) infection and hepatocellular carcinoma (HCC). This study analyzed the association of circulating soluble PD-1 (sPD-1) levels with the phases and clinical diseases in chronic HBV infection. Serum sPD-1 levels were determined by enzyme linked immunosorbent assay in patients with different phases and liver diseases of chronic HBV infection. The sPD-1 levels in patients with chronic HBV infection were significantly elevated compared with HBV infection resolvers or healthy controls...

BACKGROUND & AIMS: An abundance of non-invasive scores have been associated with fibrosis and hepatocellular carcinoma (HCC) development. We aimed to compare the prognostic ability of these scores in relation to liver histology in chronic hepatitis B (CHB) patients. METHODS: Liver biopsies from treatment-naïve CHB patients at one tertiary care centre were scored by a single hepato-pathologist. Laboratory values at liver biopsy were used to calculate the PAGE-B, REACH-B, GAG-HCC, CU-HCC, and FIB-4 scores...

PROBLEM: In chronic hepatitis B (CHB) carriers, alanine transaminase (ALT) flares are common in the peripartum period. There are limited data on immunological changes of pregnancy in CHB. We hypothesize that in pregnant CHB carriers, the Th1/Th2 cytokine ratio is altered resulting in changes in biochemical/virological and liver fibrosis markers. STUDY METHODS: Serum from 38 pregnant/post-partum CHB carriers (median age 32 years, 53% Asian, 8 HBeAg(+) ) was tested for HBV DNA, quantitative HBV surface antigen, ALT and liver fibrosis by transient elastography (TE)...

Toll-like receptors (TLRs) play a crucial role in innate and adaptive immunity, protecting the host from viral pathogens. Studies have implicated that TLR5 is associated with various diseases such as autoimmune and inflammation related diseases. However, little is known about the relationship between TLR5 and hepatitis B virus (HBV) infection. We studied the effect of TLR5 gene polymorphisms on susceptibility to and disease progression of chronic hepatitis B (CHB) infection in Chinese. Blood samples were taken from 636 patients with CHB, HBV-related liver cirrhosis (LC) or hepatocellular carcinoma (HCC) and 273 controls...

GPR40 (FFA1) is a fatty acid receptor whose activation results in potent glucose lowering and insulinotropic effects in vivo. Several reports illustrate that GPR40 agonists exert glucose lowering in diabetic humans. To assess the mechanisms by which GPR40 partial agonists improve glucose homeostasis, we evaluated the effects of MK-2305, a potent and selective partial GPR40 agonist, in diabetic Goto Kakizaki rats. MK-2305 decreased fasting glucose after acute and chronic treatment. MK-2305-mediated changes in glucose were coupled with increases in plasma insulin during hyperglycemia and glucose challenges but not during fasting, when glucose was normalized...

Although oxymatrine (OMT) has been shown to directly inhibit the replication of hepatitis B virus (HBV) in vitro, limited research has been done with this drug in vivo. In the present study, the antiviral effect of OMT was investigated in an immunocompetent mouse model of chronic HBV infection. The infection was achieved by tail vein injection of a large volume of DNA solution. OMT (2.2, 6.7 and 20 mg/kg) was administered by daily intraperitoneal injection for 6 weeks. The efficacy of OMT was evaluated by the levels of HBV DNA, hepatitis B surface antigen (HBsAg), hepatitis B e antigen (HBeAg) and hepatitis B core antigen (HBcAg)...

Mother-to-child transmission (MTCT) of hepatitis B virus (HBV) remains high even with the proper use of active-passive immunoprophylaxis in newborns. Mothers with significant viremia are at a much higher risk of MTCT; therefore, treatments aimed at lowering HBV DNA levels during pregnancy may ultimately decrease global disease burden. The exact threshold for treatment remains controversial; however, most studies have accepted levels greater than 2 × 5 log10 IU/mL as significant viremia. We reviewed the most recent literature on antiviral efficacy, maternal and fetal safety, and viral resistance patterns when used for short-duration therapy in pregnancy...

Chronic hepatitis B is a persistent and progressive inflammatory liver disease caused by infection with the hepatitis B virus (HBV). More than 240 million individuals are infected with HBV worldwide and hepatitis B accounts for an estimated 650 000 deaths annually. Approximately up to 30% of chronically infected patients will develop complications of HBV infection including, but not limited to, liver cirrhosis, end-stage liver disease, and hepatocellular carcinoma. Currently approved therapies have improved clinical outcomes, but have a considerable side-effect profile, elevated cost, and a finite course of treatment...
