Purpose - To evaluate whether Doppler sonography measurement of portal flow velocity (PFV) after glucagon injection can be useful in assessing the severity of liver damage in chronic HCV infection. Methods - Forty-five patients (32 males and 13 females; mean age 54.1 14.8 years) with biochemical (raised serum ALT levels), virological (positive serum HCV RNA test) and histological (liver biopsy) evidence of chronic HCV infection were included in the study. According to hepatitis staging (degree of liver fibrosis), as assessed by Knodell histological activity index, patients were divided into three groups: group 1 (n.=17), with no or mild fibrosis (fibrosis score: 0-1); group 2 (n.=11), with severe fibrosis (score: 3); and group 3 (n.=17), with liver cirrhosis (score: 4). For sonographic measurements of PFV, a Doppler ultrasound multi-purpose equipment and a convex 3.5 MHz probe were used. All patients were examined after an 8-hour fast, in supine position, 10 min before (baseline), as well as 5 and 10 min after, intravenous administration of 1 mg of glucagon chloride (Novo Nordisk). Statistical analysis was performed by ANOVA test, Bonferroni t test and Spearman rank correlation test. Results - No significant differences were found in mean basal PFV of group 1 (19.4 2.4 cm/sec), group 2 (20.1 3.6 cm/sec) and group 3 (17.5 3.7 cm/sec) (p > 0.05). Five minutes after glucagon injection, all the three groups showed a significant increase in PFV (25.6 4.8,23.7 4.0 and 19.5 5.0 cm/sec, respectively; p < 0.05 vs baseline). The peak increase in PFV after glucagon injection was significantly higher in group 1 (7.9 3.7 cm/sec; 40.7% of basal value) than in group 2 (4.5 3.9 cm/sec; 22.4%) (p < 0.05) and in group 3 (2.7+2.3 cm/sec; 15.4%) (p < 0.05). A significant (p< 0.001) inverse correlation was also found between the patients fibrosis scores and peak increments of PFV induced by glucagon. Conclusions - In some patients with chronic HCV infection, Doppler sonography measurement of PFV after glucagon injection can be useful, in combination with other non invasive ultrasound investigations, both in staging of liver disease and in monitoring the progression of liver histological damage.

Purpose: The research intended to present prospective data on the long-term prognosis of individuals with hepatitis C virus (HCV) infection who received direct-acting antiviral agent (DAA) treatment.
Patients And Methods: Patients who received DAA treatment at Tianjin Third Central Hospital and Tianjin Second People's Hospital were prospectively enrolled and subsequently underwent a longitudinal follow-up. This research monitored occurrences of virological relapse, hepatocellular carcinoma (HCC), mortality, and liver disease progression.

Background And Study Aims: Hepatitis C virus (HCV) infection is a significant problem in Egypt, as it is associated with various hematological disorders, both benign and malignant. In Egypt, direct-acting antivirals (DAAs) serve as the principal therapy for HCV to achieve a sustained virological response (SVR). This study investigated the effects of sofosbuvir (SOF) and daclatasvir (DCV) on HCV patients with benign blood index abnormalities and examined the correlation between these abnormalities and SVR.

Objective: Interleukin IL-17A and IL-17F are critical cytokines involved in inflammatory processes. Genetic variations in IL-17A and IL-17F might be linked to chronic hepatitis C (CHC) and an increased risk of hepatocellular carcinoma (HCC), a cancer associated with long-term inflammation. This study aims to examine the relationship between specific polymorphisms in IL-17A (rs2275913) and IL-17F (rs763780) and their association with HCV-related HCC in an Egyptian population.

This study aimed to evaluate the effectiveness of direct-acting antivirals (DAAs) on hepatitis C virus (HCV) hospitalisation trends in Italy, the country with not only the highest burden of HCV-related disease but also the highest number of patients treated for chronic HCV infection in Europe. Incident hospital discharge records in Italy from 2012 to 2019 that included a liver cirrhosis diagnosis without mention of alcohol, hepatocellular carcinoma (HCC), HCV and liver cirrhosis without mention of alcohol and/or HCC, cirrhosis with mention of alcohol, as defined by the International Classification of Diseases (ICD-9-CM) were reviewed. An interrupted time series analysis compared the incidence of cirrhosis and HCC before and after the introduction of DAAs (Year 2015).

Steatotic liver disease is prevalent among people with hepatitis C virus (HCV). The new definition of metabolic dysfunction-associated steatotic liver disease (MASLD) emphasises the metabolic drivers of steatosis and recognises its frequent coexistence with other chronic liver diseases, including HCV. We aimed to evaluate the association of coexisting MASLD and HCV with liver fibrosis.
