RESUMO

We have recently demonstrated the ability of a simple predictive model (GES) score to determine the risk of hepatocellular carcinoma (HCC) after using direct-acting antivirals. However, our results were restricted to Egyptian patients with hepatitis C virus (HCV) genotype 4. Therefore, we studied a large, independent cohort of multiethnic populations through our international collaborative activity. Depending on their GES scores, patients are stratified into low risk (≤ 6/12.5), intermediate risk (> 6-7.5/12.5), and high risk (> 7.5/12.5) for HCC. A total of 12,038 patients with chronic HCV were analyzed in this study, of whom 11,202 were recruited from 54 centers in France, Japan, India, the U.S., and Spain, and the remaining 836 were selected from the Gilead-sponsored randomized controlled trial conducted across the U.S., Europe, Canada, and Australia. Descriptive statistics and log-rank tests. The performance of the GES score was evaluated using Harrell's C-index (HCI). The GES score proved successful at stratifying all patients into 3 risk groups, namely low-risk, intermediate-risk, and high-risk. It also displayed significant predictive value for HCC development in all participants (p < .0001), with HCI ranging from 0.55 to 0.76 among all cohorts after adjusting for HCV genotypes and patient ethnicities. The GES score can be used to stratify HCV patients into 3 categories of risk for HCC, namely low-risk, intermediate-risk, and high-risk, irrespective of their ethnicities or HCV genotypes. This international multicenter validation may allow the use of GES score in individualized HCC risk-based surveillance programs.

RESUMO

Background: Direct-acting antivirals can cure ≥95% of hepatitis C virus (HCV) cases, but do not reach everyone in need. This cross-sectional study analyses the HCV cascade of care (CoC) in Madrid, Spain, in high-risk patients, to inform micro-elimination measures. Methods: From September 2019 to May 2021, data from medical records were collected and analysed from six public hospitals in Madrid, including seven adult, high-risk patient groups: patients in haemodialysis or pre-dialysis programmes, co-infected with HIV, with advanced liver disease (ALD), with hereditary haematological diseases, with transplants and people who inject drugs (PWID). Results: Here we present an analysis of 3994 patients (68.8% male), 91.2% were tested for anti-HCV and 28.9% were positive. Of the total, 34.5% were tested for HCV-RNA and 62.4% of these were positive. Of those HCV-RNA positive, 98.0% were treatment-eligible: in 7.4%, treatment is ongoing and in 89.3% completed. Of the latter, 92.2% obtained a sustained virological response 12 weeks post treatment (SVR12). Of those with ongoing or completed treatment, 9.8% experienced loss to follow-up (LTFU) or had unknown SVR12, 50.3% developed hepatic and 20.3% extrahepatic complications. ALD patients had the highest proportion of HCV-RNA positives (32.5%). The lowest proportion of patients treated were PWID (85.2%). Conclusions: Almost one in ten high-risk patients in six of Madrid's public hospitals remains untested for HCV antibodies. An almost equal percentage of those untested have experienced LTFU, with the highest proportion in PWID. This approach to monitoring the HCV CoC is vital to inform measures to eliminate HCV in hospitals.
