OBJECTIVE: All commercial assays used to measure the presence of Hepatitis C virus (HCV) antibodies set cut-off points to categorise the results, but the problem of false positive results in screening hepatitis C sera is well known. The aim of this study was to evaluate the results obtained by two chemiluminescent assays in selected sera, and compare these results with the detection of viral RNA in the specimens studied. MATERIAL AND METHODS: Two hundred reactive sera (positive) were selected, although with a low signal to cut-off ratio (S/CO), were selected, using two chemiluminescent assays and were then subjected to genome amplification...

Seng Gee Lim
With the arrival of all-oral directly acting antiviral (DAA) therapy with high cure rates, the promise of hepatitis C virus (HCV) eradication is within closer reach. The availability of generic DAAs has improved access to countries with constrained resources. However, therapy is only one component of the HCV care continuum, which is the framework for HCV management from identifying patients to cure. The large number of undiagnosed HCV cases is the biggest concern, and strategies to address this are needed, as risk factor screening is suboptimal, detecting <20% of known cases...

Treatment of hepatitis C is based on a national consensus guideline updated six-monthly according to local availability and affordability of approved therapies through a transparent allocation system in Hungary. This updated guideline incorporates some special new aspects, including recommendations for screening, diagnostics, use and allocation of novel direct acting antiviral agents. Indication of therapy in patients with no contraindication is based on demonstration of viral replication with consequent inflammation and/or fibrosis in the liver...

Chronic hepatitis C virus (HCV) infection is one of the main causes of chronic liver disease worldwide. In the last 5 years, treatment for HCV infection has experienced a marked development. In 2014, the use of ledipasvir/sofosbuvir with or without concomitant weight-based ribavirin was approved with a very significant increase in the sustained virological response. However, new side effects have been associated. We report the first case of an HCV infected patient treated for 12 wk with the combination of sofosbuvir/ledipasvir plus ribavirin who developed a miliary tuberculosis (TB) infection while on therapy...

Certain autoimmune conditions are associated with an increased risk of lymphoid malignancy. We report a 65-year old patient with autoimmune hemolytic anemia (AIHA) complicated by a follicular lymphoma (FL) in situ and other B-cell clones in the spleen. This diagnosis was made by immunohistochemistry, flow cytometry, and Southern blot analysis of the B-cell receptor. Chromosomal analysis revealed 46,XX,t(14;18)(q32;q21) 2/20, 46,XX,del(7)(q?),del(11)(q?) 2/20, and 46,XX 16/20. It has been speculated that these preneoplastic conditions do not progress to overt FL and other lymphomas without a second lymphomagenic insult...

OBJECTIVE AND METHOD: We developed and evaluated five novel real-time RT-PCR assays targeting conserved regions in the 5'-untranslated region (5'-UTR), envelope (E'), non-structural protein 2A (NS2A), NS5, and 3'-UTR of the ZIKV genome. RESULTS: The ZIKV-5'-UTR assay exhibited the lowest in-vitro limit of detection (5-10 RNA copies/reaction and 3.0×10(-1) plaque-forming units/ml). Compared to the modified version of a widely adopted RT-PCR assay targeting the ZIKV-E gene, the ZIKV-5'-UTR assay showed better sensitivity in human clinical specimens, and representative mouse specimens, including many organs which are known to be involved in human ZIKV infection but difficult to obtain in clinical settings...

A 6-year-old boy presented with a 3-month history of high-grade fever and night-sweats but without chills/rigors. On examination, he had moderate hepatosplenomegaly with multiple enlarged cervical and axillary lymph nodes. His hemogram revealed anemia and marked eosinophilia. Initial investigations were negative, except anti-HCV IgG antibodies, that were positive. Bone marrow aspirate showed a single histiocyte containing suspicious intracellular yeast-like forms. Cervical lymph node aspiration revealed a heavy load of intra- and extra-cellular Histoplasma spp...

BACKGROUND: Immigrants originating from intermediate and high HCV prevalence countries may be at increased risk of exposure to hepatitis C infection (HCV) in their countries of origin, however they are not routinely screened after arrival in most low HCV prevalence host countries. We aimed to describe the epidemiology of HCV in immigrants compared to the Canadian born population. METHODS: Using the reportable infectious disease database linked to the landed immigration database and several provincial administrative databases, we assembled a cohort of all reported cases of HCV in Quebec, Canada (1998-2008)...

BACKGROUND: Anti-HCV assays are widely used as a screening tool for HCV infection. However, diagnostic performances and effective signal-to-cut-off ratios (S/COs) for predicting true HCV infections would vary according to the assays used. Thus, we evaluated the diagnostic performances of the new Elecsys Anti-HCV assay. METHODS: A total of 41 694 cases tested by the Elecsys Anti-HCV II assay (Roche Diagnostics, Germany) during January 2013 to December 2015 were retrospectively analyzed by comparing with the diagnosis on HCV infections determined by patients' medical records and results of laboratory tests...

The II Conference of the Group for the Study of Viral Hepatitis (GEHEP) (29 September-1 October, Spain) updated epidemiological, diagnostic and treatment aspects on viral hepatitis. The conference was mostly focused on the latest news related to HCV infection, including the successes achieved since the implementation of direct-acting antiviral agents for HCV therapy, but also in the new, future challenges for a real HCV eradication. The scenario for chronic HCV infection has dramatically changed in the last two years and most patients have been cured after 12 weeks of therapy with minimal side effects...

BACKGROUND: Noninvasive evaluation of hepatic fibrosis is a growing scientific effort in medicine and is of particular interest as early diagnosis is important for the timely prevention and treatment of liver fibrosis and cirrhosis. Non-invasive markers of liver fibrosis have recently been developed as an alternative to liver biopsy. Aim of the work: The aim of this study was to assess the diagnostic value of serum microRNA 122 in Egyptian chronic hepatitis C virus infected patients. This may be a useful tool as a non invasive diagnostic test to detect early stages of fibrosis in comparison to 4 non invasive indexes (APRI, Forns, FIB-4, and FI) vs...

BACKGROUND: Hepatitis C Virus (HCV) risk is elevated for individuals with an opioid use disorder (OUD). Routine HCV testing is recommended for high-risk individuals, including those with an injection drug use history. HCV antibody testing addresses the first step in the HCV treatment care cascade, with uptake and completion of HCV treatment among individuals with chronic HCV as the optimal care cascade endpoint. The aim of this study was to characterize self-reported HCV treatment cascade outcomes among individuals with an OUD in outpatient medication assisted treatment (MAT)...

INTRODUCTION: In the U.S., the burden of hepatitis C virus (HCV) infection and associated sequelae is substantial. HCV prevalence is highest among those born in 1945-1965 (Birth Cohort). Newly diagnosed infections are increasing in younger people concurrent with rising opioid/heroin use. The Centers for Disease Control and Prevention (2012) and U.S. Preventive Services Task Force (2013) recommend HCV testing for at-risk individuals and one-time testing for the Birth Cohort. This study describes national trends in HCV antibody testing from 2005 to 2014...
