RESUMO
BACKGROUND: Direct-acting antiviral (DAA) treatment has revolutionized hepatitis C virus (HCV) care. We aimed to evaluate the risk for the development of hepatocellular carcinoma (HCC) in patients aged 75-84 years with chronic hepatitis C after HCV elimination. METHODS: This multicenter cohort study included 2405 consecutive patients with chronic hepatitis C without a history of HCC who achieved HCV elimination by DAAs. Patients in whom HCC developed within 1 year of DAA initiation were excluded. Propensity score matching analysis was used to evaluate differences in HCC risk between patients aged 75-84 versus 60-74 years. RESULTS: The median observational period was 3.5 years. Among patients aged 75-84 years with a high Fibrosis-4 (FIB-4) index (≥3.25 at baseline), there was no significant difference in the annual incidence of HCCs between groups with an FIB-4 index ≥3.25 (2.75 per 100 person-years [PY]) versus <3.25 (2.16 per 100 PY) at 12 weeks after the end of treatment, unlike the results in those aged 60-74 years (3.61 and 1.51 per 100 PY, respectively) (adjusted hazard ratio, 2.20; P = .04). In 495 pairs matched by propensity score matching, in patients without cirrhosis, the cumulative HCC incidence was significantly higher in the 75-84-year than in the 60-74-year age group (P = .04). CONCLUSIONS: Older patients aged 75-84 years remained at high risk for the development of HCC, even after HCV elimination and the improvement of the FIB-4 index to <3.25.

BACKGROUND AND AIM: Early hepatocellular carcinoma (HCC) recurrence is common, even after achieving hepatitis C virus (HCV) cure. This study was carried out to assess the long-term trends and predictors of recurrence after HCV cure by direct-acting antivirals (DAAs). METHODS: This retrospective, multicenter cohort study enrolled 365 consecutive patients with chronic hepatitis C who required HCC treatment following sustained viral response (SVR) by DAA administration. Patients with HCC recurrence before SVR were excluded. Late HCC recurrence and its predictors beyond the post-treatment early phase (24 weeks after SVR) were evaluated. RESULTS: The data of 326 patients were available for the final analysis. The median follow-up duration from SVR determination was 2.7 years. Median age was 74, and 220 (67.5%) were 70 or over. The corresponding 5-year cumulative HCC recurrence rates of previous curative and palliative treatment groups were 45.4% and 65.7%, respectively (log-rank test: P < 0.001). Cox regression multivariable analysis revealed that cirrhosis (hazard ratio [HR] 1.85, P = 0.021), the number of HCC nodules (≥ 2) (HR 1.52, P = 0.031), and previous palliative HCC treatment (HR 1.71, P = 0.012) were independent predictors of late recurrence, in addition to the predictors of early recurrence; AFP > 7 ng/mL at 12 weeks after DAA administration, time from HCC complete response (CR) to DAA initiation (< 1 year), and the number of HCC treatments necessary to achieve CR (≥ 2). CONCLUSIONS: The evaluation of fibrosis and characteristics of the previous HCC would allow for better HCC recurrence stratification, which would be helpful for developing long-term surveillance strategies.

BACKGROUND AND AIMS: Outcome data of sequential hepatitis B virus treatment with tenofovir alafenamide (TAF) are limited. We aimed to assess the effectiveness and renal safety of TAF in chronic hepatitis B (CHB) patients who were previously treated with entecavir (ETV), tenofovir disoproxil fumarate (TDF), or a nucleos(t)ide analogue (NA) combination. METHODS: This multicenter, retrospective, cohort study included 458 consecutive CHB patients who switched to TAF monotherapy after at least 2 years of treatment with another NA. The longitudinal virological/laboratory responses were evaluated up to 96 weeks after switchover. Chronic kidney disease (CKD) was defined as an estimated glomerular filtration rate (eGFR) < 60 mL/min/1.73 m2. RESULTS: The proportions of complete viral suppression (CVS) (HBV DNA < 20 IU/mL) at week 96 were 99.0%, 98.5%, and 98.4% in the prior ETV (n = 198), TDF (n = 137), and NA combination (n = 123) groups, respectively. Almost all patients with HBV DNA of 20-2000 IU/mL at baseline achieved CVS at week 96. On multivariable generalized estimated equation analysis, a low quantitative hepatitis surface antigen (qHBsAg) level at baseline was associated with a lower follow-up qHBsAg level (coefficient 0.81, p < 0.001). The eGFR showed greater improvement in patients with CKD compared to those without (coefficient 21.7, p < 0.001). However, the increase of eGFR reached a peak between weeks 24 and 48. CONCLUSIONS: Based on this longitudinal data analysis up to 96 weeks, sequential NA therapy with a switch to TAF is a good option to achieve high viral suppression and renal safety.

BACKGROUND: Tenofovir alafenamide (TAF) may be preferable to other nucleos(t)ide analogues (NA) regarding outcomes against chronic hepatitis B virus (HBV) infection. AIMS: To evaluate the longer term virological/biochemical effectiveness of TAF and the renal safety of sequential therapy to TAF in real-world settings METHODS: This multi-centre, retrospective cohort study included consecutive adult patients who were switched from other NAs to TAF. We assessed the virological and biochemical responses up to 144 weeks. We performed sensitivity analyses for a subgroup with chronic kidney disease (CKD) at baseline. RESULTS: We analysed the data of 391 patients with chronic hepatitis B previously treated with entecavir (ETV) (n = 174), tenofovir disoproxil fumarate (TDF) (n = 116) or an NA combination (n = 101) for ≥ 24 months. HBV DNA <10 IU/ml at week 144 was found for 99% of patients, regardless of prior NA regimen or HBV DNA level at baseline. For patients who switched from TDF to TAF, total, low-density lipoprotein, high-density lipoprotein cholesterol and triglycerides were significantly increased after the switch. Patients who switched from a nucleotide analogue to TAF had an improved estimated glomerular filtration rate, although the rate of hypophosphataemia (<2.5 mg/dl) remained 9.7% at week 144. The virological and biochemical responses of patients with CKD were similar to the overall results. CONCLUSIONS: Switching to TAF remained effective and safe for up to 3 years. Given the increasing comorbidities related to ageing, it will be important to carefully follow the change in the lipid levels of patients with a prior TDF-based regimen.

Advanced fibrosis/cirrhosis and related biomarkers have been recognized as useful predictors of the development of hepatocellular carcinoma (HCC) by patients with chronic hepatitis C (CHC) following hepatitis C virus (HCV) cure by direct-acting antivirals (DAAs). However, it remains unclear if DAAs themselves have an influence on or facilitate the development of HCC. This multicenter cohort study included CHC patients without a history of HCC who achieved HCV elimination by DAAs. Cohorts of 835 patients treated with a sofosbuvir (SOF)-based regimen and 835 treated with a SOF-free regimen were matched 1:1 by propensity scoring with nine variables to evaluate differences in HCC incidence. The median observation period was 3.5 years. Sixty-nine cases of HCC were found during 5483.9 person-years (PY) over the entire follow-up period. The annual incidence was similar for both groups (SOF-based 1.25 and SOF-free 1.27 per 100 PY, respectively: adjusted hazard ratio (HR) 1.26, 95% confidence interval (CI) 0.75-2.12, p = 0.39). However, the annual incidence within the first two years was higher for patients treated with SOF than for those without, but did not reach significance (1.50 and 0.97 per 100 PY incidence rates, respectively: adjusted HR 2.05, 95% CI 0.98-4.25, p = 0.06). In summary, DAA treatment with SOF was not associated with an increase in the development of de novo HCC.
