RESUMO

BACKGROUND AND STUDY AIMS: Hepatitis C virus (HCV) infection often causes asymptomatic disease and patients are frequently diagnosed at an advanced stage. Oral direct acting antivirals (DAAs) are successful in treating HCV with high sustained virologic response (SVR) and excellent tolerability. The aim of this study is to evaluate cost-effectiveness of a broad screening strategy proposing screening to all undiagnosed members of a population (comprehensive HCV screening), in the general adult population, emergency department (ED) attendees, men who have sex with men (MSM) and people who inject drugs (PWID). PATIENTS AND METHODS: We populated a theoretical model with Belgian data. A decision tree model simulating HCV screening and diagnosis was combined with a Markov state transition model simulating treatment. There was one screening round per year during five years. In the ED population only one screening round was considered. RESULTS: The model calculated that more HCV patients could be detected and treated with comprehensive screening compared to the current situation. Incremental cost per incremental quality adjusted life years (QALY) gained was lower than 10.000€/QALY for one and for five screening rounds in the general population (5.139 and 5.200 respectively), in ED attendees (one screening round 5.967), in MSMs (4.292 and 4.302 respectively) and in PWIDs (3.504 and 3.524 respectively). CONCLUSION: A broad screening strategy combined with treatment is likely to be a cost-effective strategy to detect and treat HCV infected patients and diminish the HCV burden in Belgium.

RESUMO

BACKGROUND AND STUDY AIMS: Although multiple HCV prevalence studies were recently performed in the general population from Belgium, they suffer from a lack of geographical representativeness, an insufficient number of participants or a lack of inclusion of high prevalence groups. The aim of this study is to provide robust information on the HCV burden. METHODS: Recently performed HCV prevalence studies in the general, adult population were included in this study, based on well-defined selection criteria. A meta-analysis was performed to estimate the seroprevalence, the prevalence of participants with viremia and the prevalence estimation for people with viremia which were unaware of their status. RESULTS: Eight studies fulfilled the criteria for inclusion of the quantitative prevalence estimation. Based on the meta-analysis on these 8 studies, we estimated an HCV seroprevalence of 1.01% [95% CI : 0.66-1.42%], representing a total of 90,722 adult, HCV seropositives of which 64,412 individuals (0.71%) were confirmed seropositive. Based on the RNA presence, an estimated viremic prevalence of 0.33% [95% CI : 0.21-0.47 %] was determined, corresponding with 29,642 individuals. This is 46,0% of the true HCV seropositive residents. Further, based on the availability of patient information in 5 out of the 8 studies, a prevalence of 0.18% [95% CI : 0.07-0.33] representing 16,168 individuals from the adult Belgian population are unaware of their HCV status. CONCLUSIONS: We believe that the quantitative measurement by the meta-analysis will be more reliable for their use in the design of a screening strategy or in the development of prevention campaigns as compared to the prevalence estimations performed at local level.

RESUMO

Recently, concerns were raised of high rates of HCC recurrence in patients treated with direct-acting antivirals (DAA) for hepatitis C infection. We investigated the HCC occurrence and recurrence rates within 6 months after treatment with DAA with or without pegylated interferon (PEG-IFN) in real life. This is a retrospective, multicenter cohort trial, executed in 15 hospitals distributed across Belgium. Populations were matched based on fibrosis score (Metavir F3-F4). Patients with a Child-Pugh score ≥ B were excluded. In total, 567 patients were included, of whom 77 were treated with PEG-IFN+DAA between 2008 and 2013 and 490 with DAA without PEG-IFN between 2013 and 2015. Patients treated with PEG-IFN+DAA (53±9y) were younger than patients treated with DAA without PEG-IFN (59±12y) (P=.001). 47% of patients treated with PEG-IFN+DAA were in the F4 stage vs 67% of patients treated with DAA without PEG-IFN (P=.001). Screening was inadequate in 20% of both patient groups (P=.664). The early occurrence rate of HCC was 1.7% and 1.1% in patients treated with DAA with and without PEG-IFN, respectively (P=.540). The early recurrence rate was 0% in patients treated with PEG-IFN+DAA and 15.0% in patients treated with DAA without PEG-IFN (P=.857). There is no difference in early occurrence of new HCC between patients treated with DAA with and without PEG-IFN. We did observe a high early recurrence rate of HCC in patients treated with DAA without PEG-IFN. However, these patients were at baseline more at risk for HCC. Finally, in 20%, screening for HCC was inadequate.
