Interleukin (IL)-12 plays an essential role in host defense against infectious diseases. Serum IL-12 concentration and blood mononuclear cell production with or without specific interferon (IFN)-gamma priming were investigated in 65 chronic hepatitis C virus (HCV) patients and 25 healthy donors. HCV patients had higher serum IL-12 levels (P = .004) and produced higher amounts after IFN-gamma pr...

Although myeloid-derived suppressor cells (MDSCs) are well known for their immunosuppressive function in several pathological conditions, the role of MDSCs in hepatitis B virus infection remains obscure. In this study, we investigated the frequency and function of MDSCs in the peripheral blood and liver of 91 chronic hepatitis B (CHB) patients. A higher percentage of MDSCs, defined as CD14(+)HL...

Nonalcoholic fatty liver disease (NAFLD), defined as abnormal accumulation (> 5%) of hepatic triglyceride without excess alcohol intake, is the most common form of chronic liver disease in adults and children in the United States. NAFLD encompasses a spectrum of histologic findings including uncomplicated steatosis, steatosis with inflammation and steatohepatitis [nonalcoholic steatohepatitis (...

BACKGROUND/AIMS The distribution of blood lipids, glucose and their determinants in thalassemic patients with chronic hepatitis C virus (HCV) infection has rarely been investigated. Thus, we aimed to investigate the relationship between both liver histologic findings and viral markers and serum lipids in thalassemic patients chronically infected with HCV. METHODS We enrolled 280 polytransfuse...

BACKGROUND Hepatitis C recurring after orthotopic liver transplantation varies in severity and some patients rapidly develop fully established liver cirrhosis. Neither clinical nor biological markers of such rapid cirrhotic evolution are available. AIM To assess the value of histology in identifying patients who will develop cirrhosis shortly after liver transplantation. PATIENTS AND METHOD...

We investigated the potential of 16-desmethyl tirilazad mesylate, a member of 21-aminosteroids, to ameliorate alcohol-induced liver injury. Four groups (five rats/group) of male Wistar rats were studied. One group of rats was fed fish oil and ethanol (FE) for 4 weeks, and a second group received isocaloric amounts of dextrose instead of ethanol (FD). The third (FE-LAZ) and fourth (FD-LAZ) group...

BACKGROUND AND AIMS Liver diseases are associated with significant morbidity and health- related expenditure. Although cost-effective treatments are available, the disease is often asymptomatic until late in its course. "Medex Test," is the noninvasive detection of liver abnormalities by the measurement of changes in electrical impedance of dermal zones. This method is based on neuroreflexology...

BACKGROUND Cancer stem cells (CSCs) play a critical role in tumor development, progression, metastasis and recurrence. AIM To evaluate hepatic expression of CD44 and CD133 in Egyptian patients with HCV-induced chronic liver diseases and hepatocellular carcinomas (HCCs), and to assess its correlation with inflammatory activity scores, stages of fibrosis (in chronic hepatitis with or without ci...

Nonalcoholic fatty liver disease is associated with chronic oxidative stress. In our study, we explored the antioxidant effect of antidiabetic metformin on chronic [high-fat diet (HFD)-induced] and acute oxidative stress induced by short-term warm partial ischemia-reperfusion (I/R) or on a combination of both in the liver. Wistar rats were fed a standard diet (SD) or HFD for 10 wk, half of them...

BACKGROUND Few studies have investigated predictors of discordance between liver biopsy (LB) and liver stiffness measurement (LSM) using FibroScan®. We assessed predictors of discordance between LB and LSM in chronic hepatitis B (CHB) and investigated the effects of necroinflammatory activity. METHODS In total, 150 patients (107 men, 43 women) were prospectively enrolled. Only LSM with ≥ 10 v...
