Background: The Daan HCV RNA quantitative assay was a recently developed kit with high sensitivity for the detection of HCV RNA. We aimed to evaluate the analytical performance of the Daan HCV RNA quantitative assay and compare it with the COBAS AmpliPrep/COBAS TaqMan HCV Quantitative Test, v2.0.
Method: WHO HCV RNA standard, NIBSC 06/102 standard, and CLSI EP documents were used to evaluate the precision, accuracy, linearity, anti-interference ability, and cross-reactivity of the Daan HCV RNA quantitative assay. Overall 198 clinical serum specimens were used to make comparison between the Daan HCV RNA quantitative assay and the Roche Cobas test.
Results: The within-run precision (S ), and total precision (S ) for 6.11 log IU/mL, 4.22 log IU/mL, and 2.32 log IU/mL HCV RNA were 0.13 and 0.15, 0.07 and 0.09, and 0.11 and 0.10, respectively. The linear range was 20-10 IU/mL, and the limit of detection was 15 IU/mL. It did not display any interference with commonly encountered conditions and cross-reactivity with some common virus. A good agreement was observed between the Daan HCV RNA quantitative assay and the Roche Cobas test.
Conclusion: The Daan HCV RNA quantitative assay has shown satisfactory performances and excellent agreement with COBAS HCV Quantitative Test on clinical specimens with lower cost, which provides an alternative choice for the diagnosis and monitoring of HCV infection in developing countries.

Background: Nonenveloped viruses, such as hepatitis A virus (HAV) and parvovirus B19 (B19V), are not inactivated by detergents and solvents commonly used to manufacture plasma derivatives. Cases of transfusion-transmitted HAV and B19V have already been described in several countries. This study aimed to determine the incidence of HAV and B19V asymptomatic infections in blood donors from Rio de Janeiro and evaluate the residual risk of transmission to blood derivative recipients.

Introduction: Artificial intelligence (AI) allows the optimization of diagnostic processes for hepatitis C virus (HCV) patients. Our objective was to evaluate the clinical, economic, and management benefits of an AI-based clinical decision support system (Intelligen-C strategy).
Methods: The Intelligen-C strategy consisted of (1) a retrospective phase (Dec 2013-Sep 2021), in which medical records were reviewed to search for anti-HCV-positive and/or HCV-RNA-positive patients lost in the system, and (2) a prospective phase (Feb 2022-Jan 2023), in which automated screening (40-70 years) and routine testing for risk factors were performed in patients who were admitted to the emergency department or were hospitalized.
Changes in Vascular Endothelial Growth Factor and Development of Hepatocellular Carcinoma in Direct-Acting Antiviral Drugs (DAAs)-Treated Hepatitis C Virus (HCV) Patients.

Department of Hepatology, Gastroenterology, and Infectious Diseases, Al-Azhar University, Assiut, EGY.
Background There is ongoing debate regarding the impact of direct-acting antiviral drugs (DAAs) on the occurrence of de novo hepatocellular carcinoma (HCC). Vascular endothelial growth factor (VEGF) plays a crucial role in the development and angiogenesis of HCC. Aim This study aims to evaluate dynamic changes in vascular endothelial growth factor (VEGF) levels at different point times during and after treatment of HCV to evaluate the risk of de novo HCC in DAAs-treated HCV patients.

Roger Williams Institute of Liver Studies, Foundation for Liver Research, London, UK.
Background: Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD) encompasses a spectrum of histological conditions ranging from simple steatosis to fibrosing steatohepatitis, and is a risk factor for cardiovascular diseases (CVD). While oxidised apolipoproteins A and B have been linked to obesity and CVD, the association between other oxidised apolipoproteins and MASLD is yet to be established. To fill this gap, we characterised the circulating serum peptidome of patients with MASLD.

Minimal change disease (MCD) accounts for 10 - 15% of idiopathic nephrotic syndromes in adults. Chronic hepatitis C virus (HCV) infection is rarely ascribed as a cause of MCD and was previously associated with interferon-based therapy. MCD in treatment-naïve chronic HCV infection is extremely rare, with only 3 cases reported in the literature.
