Store-operated Ca(2+) release-activated Ca(2+) (CRAC) channels are involved in the pathogenesis of rheumatoid arthritis (RA) and have been studied as therapeutic targets in the management of RA. We investigated the efficacy and safety of CRAC inhibitors, including a neutralizing Ab (hCRACM1-IgG) and YM-58483, in the treatment of RA. Patient-derived T cell and B cell activity was suppressed by hCRACM1-IgG as well as YM-58483. Systemically constant, s.c. infused CRAC inhibitors showed anti-inflammatory activity in a human-NOD/SCID xenograft RA model as well as protective effects against the destruction of cartilage and bone...

AIM: Chronic hepatitis B (CHB) patients with normal alanine aminotransferase (ALT) levels are not free from significant hepatic lesions. Recently, there has been an improved understanding of the clinical significance of quantitative hepatitis B core antibody levels (qAnti-HBc) during CHB management. In this cross-section study, we evaluated the utility of qAnti-HBc in identifying significant liver inflammation in CHB patients. METHODS: A total of 469 patients (the training set: 363; the validation set: 106) underwent liver biopsy (LB) were included...

The recent introduction of direct-acting antiviral drugs (DAAs) for treatment of the hepatitis C virus (HCV) has greatly improved the management of HCV for infected patients. These viral protein inhibitors act rapidly, allowing HCV clearance and increasing the sustained virological response rates. However, hepatitis B virus (HBV) reactivation has been reported in HCV/HBV co-infected patients. Hepatitis B reactivation refers to an abrupt increase in the HBV and is well-documented in patients with previously undetected HBV DNA due to inactive or resolved HBV infection...

Portal hypertension (PHT) is a frequent and severe complication of cirrhosis. PHT may lead to the development of various complications with high mortality. Liver transplantation is the gold standard as a surgical curative treatment for end-stage liver disease. Theoretically, etiological treatment focusing on the pathophysiology of the underlying disease should be the objective of the nonsurgical management of cirrhotic PHT. Chronic viral hepatitis is the major etiology of cirrhosis and PHT. In cirrhotic patients with chronic hepatitis B virus infection, antiviral therapies can suppress viral replication, ameliorate hepatic inflammation, regress fibrosis, and restore liver functional reserve...

: HIV infection has a significant impact on the natural history of chronic hepatitis B virus (HBV) infection, with increased levels of HBV DNA, accelerated progression of liver disease, and increased liver-associated mortality compared with HBV monoinfection. Widespread uptake and early initiation of HBV-active antiretroviral therapy has substantially improved the natural history of HIV-HBV coinfection but the prevalence of liver disease remains elevated in this population. In this paper, we review recent studies examining the natural history and pathogenesis of liver disease and seroconversion in HIV-HBV coinfection in the era of HBV-active antiretroviral therapy and the effects of HIV directly on liver disease...

Gene therapy has made impressive recent progress and has potential for treating a wide range of diseases, many of which are important to Africa. However, as a result of lack of direct public funding and skilled personnel, direct research on gene therapy in Africa is currently limited and resources to support the endeavor are modest. A strength of the technology is that it is based on principles of rational design, and the tools of gene therapy are now highly versatile. For example gene silencing and gene editing may be used to disable viral genes for therapeutic purposes...

Hepatitis D or delta is a chronic liver disease globally reaching 15‑20M people. Its agent, hepatitis D virus (HDV) requires the presence of hepatitis B virus (HBV) to complete its life cycle. It represents one of the most severe forms of viral hepatitis. Current therapy with pegylated interferon alpha leads to viral eradication only in 25 % of cases. New treatments targeting the virus life cycle are sought. For example Myrcludex-B, which inhibits the entry into hepatocytes, lonafarnib which prevents the assemblage of the viral particle and the molecule REP 2139 which, among other unclear mechanisms, impedes the exit of the virus...

In the United States, the fight to eradicate hepatitis C virus (HCV) infection has been ongoing for many years, but the results have been less than ideal. Historically, patients with chronic hepatitis C (CHC) were treated with interferon-based regimens, which were associated with frequent adverse effects, suboptimal response rates, and long durations of treatment - of up to 48 weeks. Expertise from specialist-physicians, such as hepatologists and gastroenterologists, was needed to closely follow patients on these medications so as to monitor laboratory values and manage adverse effects...

Colorectal cancer remains a leading cause of cancer-related death in Europe. Approximately one-quarter of patients have synchronous hepatic metastases and metachronous liver metastases occur in a further 30%. The scope of surgery in management of colorectal metastases has evolved to include selected patients with extra-hepatic disease for whom R0 resection is considered feasible; however, locoregional treatments are increasingly recognised as viable management options in those patients deemed unsuitable for surgery and there is an expanding body of evidence regarding their ability to achieve local control and increase progression-free survival in the liver...
