Atypical Presentation of a Rare Parasitic Infection with Fasciola hepatica: A Multidisciplinary Case Report.

BACKGROUND Fascioliasis is a zoonotic disease caused by Fasciola hepatica (F. hepatica). This infection is associated with a broad spectrum of clinical symptoms such as fever, eosinophilia, and gastrointestinal symptoms.

NAFLD and NASH in HCV Infection: Prevalence and Significance in Hepatic and Extrahepatic Manifestations.

The aim of this paper is to review and up to date the prevalence of hepatitis C virus (HCV)-associated non-alcoholic fatty liver disease (NAFLD) and non-alcoholic steatohepatitis (NASH) and their significance in both accelerating progression of HCV-related liver disease and development of HCV-associated extrahepatic diseases. The reported mean prevalence of HCV-related NAFLD was 55%, whereas NASH was reported in 4%-10% of cases. HCV genotype 3 directly induces fatty liver deposition, namely "viral steatosis" and it is associated with the highest prevalence and degree of severity, whereas, HCV non-3 genotype infection showed lower prevalence of steatosis, which is associated with metabolic factors and insulin resistance.

Chronic hepatitis C virus infection and neurological and psychiatric disorders: an overview.

Hepatitis C virus (HCV) infection is considered a systemic disease because of involvement of other organs and tissues concomitantly with liver disease. Among the extrahepatic manifestations, neuropsychiatric disorders have been reported in up to 50% of chronic HCV infected patients. Both the central and peripheral nervous system may be involved with a wide variety of clinical manifestations.

Insulin resistance and steatosis in HBV-HCV co-infected patients: Role of PNPLA3 polymorphisms and impact on liver fibrosis progression.

Aim: To evaluate steatosis, insulin resistance (IR) and patatin-like phospholipase domain-containing 3 (PNPLA3) and their relation to disease progression in hepatitis B and C viruses (HCV-HBV) co-infected patients.

Methods: Three hundred and thirty patients with biopsy proven chronic hepatitis were enrolled: 66 had HBV-HCV, 66 HBV and 198 HCV infection. Prevalence of steatosis, IR and PNPLA3 polymorphisms and their relation to anthropometric, biochemical, virological and histological parameters were evaluated.

Pathogenesis and significance of hepatitis C virus steatosis: an update on survival strategy of a successful pathogen.

Hepatitis C virus (HCV) is a successful pathogen on the grounds that it exploits its host's metabolism to build up viral particles; moreover it favours its own survival by inducing chronic disease and the development of specific anatomic changes in the infected organ. Steatosis, therefore, is associated with HCV infection by necessity rather than by chance alone. Approximately 6% of HCV patients have steatohepatitis.

Chronic hepatitis C virus infection and atherosclerosis: clinical impact and mechanisms.

Hepatitis C virus (HCV) infection represents a major health issue worldwide due to its burden of chronic liver disease and extrahepatic manifestations including cardiovascular diseases, which are associated with excess mortality. Analysis of published studies supports the view that HCV infection should be considered a risk factor for the development of carotid atherosclerosis, heart failure and stroke. In contrast, findings from studies addressing coronary artery disease and HCV have yielded conflicting results.

Chronic HCV infection and inflammation: Clinical impact on hepatic and extra-hepatic manifestations.

The liver has a central role in regulating inflammation by its capacity to secrete a number of proteins that control both local and systemic inflammatory responses. Chronic inflammation or an exaggerated inflammatory response can produce detrimental effects on target organs. Chronic hepatitis C virus (HCV) infection causes liver inflammation by complex and not yet well-understood molecular pathways, including direct viral effects and indirect mechanisms involving cytokine pathways, oxidative stress and steatosis induction.

Chronic HCV infection is a risk factor of ischemic stroke.

Objectives: Cerebrovascular diseases are leading cause of death worldwide. Plaque rupture and embolization account for one-third of ischemic stroke. The causes are not fully known, but inflammation plays a pathogenic role.

The predictive value of steatosis in hepatitis C virus infection.

Steatosis is a complication of hepatitis C virus (HCV) infection and the mechanisms of its development are complex, involving viral and host factors. Steatosis that is prevalently viral is associated with HCV genotype 3, and steatosis that is prevalently metabolic is associated with non-3 genotypes. Viral steatosis is correlated with the level of HCV replication, whereas metabolic steatosis is related to insulin resistance.

Chronic HCV infection is a risk of atherosclerosis. Role of HCV and HCV-related steatosis.

Objectives: HCV and NAFLD are associated with atherosclerosis in general population. The prevalence of atherosclerosis in chronic hepatitis C (CHC) patients is unknown. We hypothesized that HCV per se and HCV-related steatosis could favour atherosclerosis.

Metabolic alterations and chronic hepatitis C: treatment strategies.

Introduction: Chronic hepatitis C (HCV) infection is considered a metabolic disease. It is associated with a specific metabolic syndrome, HCV-associated dysmetabolic syndrome (HCADS), consisting of steatosis, hypocholesterolemia and insulin resistance/diabetes. These metabolic derangements contribute to a decrease in sustained virological response (SVR) to pegylated-interferon-α-ribavirin as standard of care (SOC), and are associated with progression of liver fibrosis.

Leukocyte interferon-alpha and ribavirin for treatment of chronic hepatitis C patients intolerant to pegylated-interferon.

Treatments for chronic hepatitis C (CHC) patients intolerant to pegylated interferons (peg-IFNs) are lacking. Thus, such patients remain at high risk of developing an advanced and decompensated liver disease. Leukocyte IFN-alpha (Le-IFN-alpha) seems to possess a safer profile than other natural and recombinant a-interferons, but no information is available for peg-IFN intolerant patients.

Interplay between oxidative stress and hepatic steatosis in the progression of chronic hepatitis C.

Background/aims: The contribution of oxidative stress to the pathogenesis of chronic hepatitis C (CHC) is still poorly elucidated. This study investigated the relationship between oxidative stress, insulin resistance, steatosis and fibrosis in CHC.

Methods: IgG against malondialdehyde-albumin adducts and HOMA-IR were measured as markers of oxidative stress and insulin resistance, respectively, in 107 consecutive CHC patients.
