RESUMO

Background: Primary care has a crucial role to play in the prevention, early detection, referral, and risk factor management of non-alcoholic fatty liver disease and non-alcoholic steatohepatitis (NAFLD/NASH). In 2021, a team of European collaborators developed a continuing medical education (CME) program on NAFLD/NASH that consolidates evidence and clinical best practices tailored to the primary care setting. This article reports on the methodology used to design and develop the CME and the results of a feasibility study. Methods: An expert advisory group representing both European specialists and general practitioners supported the design of the CME to be implemented in three European settings (Greece, Spain, and Netherlands). The CME features four training modules and problem-based learning using clinical case studies. The CME was tested regarding feasibility and acceptability among a sample of primary care providers (PCPs) in Greece (n = 28) with measurements occurring before, immediately after, and 1 month following the training. Outcome measures included satisfaction with the CME, changes in PCPs' knowledge, attitudes, confidence, and self-reported clinical practices related to NAFLD/NASH. Results: The CME is available as an open-access e-learning course on the European Society for Primary Care Gastroenterology education platform in English, Greek, Spanish, and Dutch. The feasibility study documented high levels of satisfaction, with 96% of PCPs reporting they were extremely or very satisfied with the overall training. Statistically significant increases in PCPs' confidence in NAFLD/NASH-related clinical practices were documented between the pre- and post-assessments. At the follow-up, 62% of GPs reported that the CME had changed their clinical practices related to NAFLD/NASH to a great extent. Conclusion: This CME intervention developed by experts and tailored to PCPs in European settings may serve as an asset for increasing knowledge, confidence, and practice behaviors related to NAFLD/NASH.

RESUMO

BACKGROUND: The introduction of highly effective direct-acting antiviral therapy has changed the hepatitis C virus (HCV) treatment paradigm. However, a recent update on HCV epidemiology in incarcerated settings is necessary to accurately determine the extent of the problem, provide information to policymakers and public healthcare, and meet the World Health Organization's goals by 2030. This systematic review and meta-analysis were performed to determine the prevalence of HCV Ab and RNA in incarcerated settings. METHODS: For this systematic review and meta-analysis, we searched PubMed, Embase, Scopus, and Web of Science for papers published between January 2013 and August 2021. We included studies with information on the prevalence of HCV Ab or RNA in incarcerated settings. A random-effects meta-analysis was done to calculate the pooled prevalence and meta-regression to explore heterogeneity. RESULTS: Ninety-two unique sources reporting data for 36 countries were included. The estimated prevalence of HCV Ab ranged from 0.3% to 74.4%. HCV RNA prevalence (available in 46 sources) ranged from 0% to 56.3%. Genotypes (available in 19 sources) 1(a) and 3 were most frequently reported in incarcerated settings. HCV/HIV coinfection (available in 36 sources) was highest in Italy, Estonia, Pakistan, and Spain. Statistical analysis revealed that almost all observed heterogeneity reflects real differences in prevalence between studies, considering I2 was very high in the meta-analysis. CONCLUSIONS: HCV in incarcerated settings is still a significant problem with a higher prevalence than in the general population. It is of utmost importance to start screening for HCV (Ab and RNA) in incarcerated settings to give clear, reliable and recent figures to plan further treatment. This is all in the context of meeting the 2030 WHO targets which are only less than a decade away. TRIAL REGISTRATION: PROSPERO: CRD42020162616.

RESUMO

BACKGROUND: There is currently no systematic screening for hepatitis C (HCV) reinfection in people who inject drugs (PWID) after treatment in Belgium. However, in a recent meta-analysis, the overall HCV reinfection rate was 5.9/100 person-years (PY) among PWID. Accordingly, this study was undertaken to investigate the reinfection rate in former and active PWID who achieved the end of treatment response after direct-acting antiviral (DAA) treatment in Belgium. METHODS: This observational cross-sectional study recruited individuals with a history of injecting drug use who had achieved the end of treatment response to any DAA treatment between 2015 and 2020. Participants were offered a post-treatment HCV RNA test. RESULTS: Eighty-five potential participants were eligible to participate and contacted, of whom 60 participants were enrolled in the study with a median age of 51.0 (IQR 44.3-56.0) years; it was reported that 23.3% continued to inject drugs intravenously after DAA treatment. Liver cirrhosis was present in 12.9%. The majority had genotype 1a (51.7%) or genotype 3 (15.0%) infection. We detected no reinfections in this study population. The total time patients were followed up for reinfection in the study was 78.5 PY (median 1.0 years IQR 0.4-2.0). CONCLUSION: Reinfection after successful treatment with DAA initially appears to be very low in Belgian PWID. Therefore, efforts should be made to screen individuals with persistent risk behaviors for reinfection systematically. In addition, a national HCV registry should be established to accurately define the burden of HCV infection and reinfection in Belgium and support the elimination of viral hepatitis C in Europe.

RESUMO

BACKGROUND: Screening and treatment of hepatitis C virus (HCV) infection in people who use drugs (PWUD) remains insufficient. Reducing the burden of HCV infection in PWUD requires interventions focusing on the different steps of the HCV care cascade. METHODS: We performed a prospective, multicenter study, evaluating the impact of an HCV care model on the HCV care cascade among PWUD attending an addiction care center in Belgium between 2015 and 2018. Interventions within the care model consisted of pre-test counseling, on-site HCV screening and case management services. A multiple logistic regression model was performed to identify the independent factors influencing the outcomes. RESULTS: During the study period, 441 PWUD were registered at the addiction care center, 90% (395/441) were contacted, 88% (349/395) were screened for HCV infection. PWUD were more likely to be screened if they had ever injected drugs (p < .001; AOR 6.411 95% CI 3.464-11.864). In 45% (157/349), the HCV antibody (Ab) test was positive, and in 27% (94/349) HCV RNA was positive. Within the Belgian reimbursement criteria (fibrosis stage ≥ F2), 44% (41/94) were treated. Specialist evaluation at the hospital was lower for PWUD receiving decentralized opioid agonist therapy (p = .005; AOR 0.430 95% CI 0.005-0.380), PWUD with unstable housing in the past 6 months before inclusion (p = .015; AOR 0.035 95% CI 0.002-0.517) or if they were recently incarcerated (p = .001; AOR 0.010 95% CI 0.001-0.164). CONCLUSIONS: This HCV care model demonstrated high screening, linkage to care, and treatment initiation among PWUD in Belgium. Using the cascade of care to guide interventions is easy and necessary to monitor results. This population needs guidance, not only for screening and treatment initiation but also for the long-term follow-up since one in six had cirrhosis and could develop hepatocellular carcinoma. Further interventions are necessary to increase linkage to care and treatment initiation. Universal access to direct-acting antiviral therapy from 2019 will contribute to achieving HCV elimination in the PWUD population.

RESUMO

BACKGROUND: Prevalence data on viral hepatitis B (HBV), hepatitis C (HCV), and HIV infection in prison are often scarce or outdated. There is currently no systematic screening for these blood-borne viral infections (BBV) in Belgian prisons. There is an urgency to assess the prevalence of these BBV to inform policymakers and public healthcare. METHODS: This was a multicentre, interventional study to assess the prevalence of BBV using opt-in screening in prisons across Belgium, April 2019 - March 2020. Prisoners were tested using a finger prick and BBV risk factors were assessed using a questionnaire. A generalized linear mixed model was used to investigate the association between the various risk factors and HCV. RESULTS: In total, 886 prisoners from 11 Belgian prisons were screened. Study uptake ranged from 16.9 to 35.4% in long-term facilities. The prevalence of HCV antibodies (Ab), hepatitis B surface antigen (Ag) and HIV Ab/Ag was 5.0% (44/886), 0.8% (7/886), and 0.2% (2/886). The adjusted odds for HCV Ab were highest in prisoners who ever injected (p < 0.001; AOR 24.6 CI 95% (5.5-215.2). The prevalence of detectable HCV RNA in the total cohort was 2.1% (19/886). Thirteen (68.4%) prisoners were redirected for follow-up of their HCV infection. CONCLUSIONS: Opt-in testing for viral hepatitis B, C and HIV was relatively well-accepted in prisons. Compared with the general population, prisoners have a higher prevalence of infection with BBV, especially for HCV. Systematic screening for these BBV should be recommended in all prisons, preferably using opt-out to optimize screening uptake.

RESUMO

An increasing percentage of people have or are at risk to develop non-alcoholic fatty liver disease (NAFLD) worldwide. NAFLD comprises different stadia going from isolated steatosis to non-alcoholic steatohepatitis (NASH). NASH is a chronic state of liver inflammation that leads to the transformation of hepatic stellate cells to myofibroblasts. These cells produce extra-cellular matrix that results in liver fibrosis. In a normal situation, fibrogenesis is a wound healing process that preserves tissue integrity. However, sustained and progressive fibrosis can become pathogenic. This process takes many years and is often asymptomatic. Therefore, patients usually present themselves with end-stage liver disease e.g., liver cirrhosis, decompensated liver disease or even hepatocellular carcinoma. Fibrosis has also been identified as the most important predictor of prognosis in patients with NAFLD. Currently, only a minority of patients with liver fibrosis are identified to be at risk and hence referred for treatment. This is not only because the disease is largely asymptomatic, but also due to the fact that currently liver biopsy is still the golden standard for accurate detection of liver fibrosis. However, performing a liver biopsy harbors some risks and requires resources and expertise, hence is not applicable in every clinical setting and is unsuitable for screening. Consequently, different non-invasive diagnostic tools, mainly based on analysis of blood or other specimens or based on imaging have been developed or are in development. In this review, we will first give an overview of the pathogenic mechanisms of the evolution from isolated steatosis to fibrosis. This serves as the basis for the subsequent discussion of the current and future diagnostic biomarkers and anti-fibrotic drugs.

RESUMO

BACKGROUND: Targeted screening for hepatitis C viral (HCV) infection is not yet widely executed in Belgium. When performed in people who use drugs (PWUD), it is mainly focused on those receiving opiate agonist therapy (OAT). We wanted to reach out to a population of difficult to reach PWUD not on centralized OAT, using non-invasive screening as a bridge to re-integration in medical care supported by facilitated referral to a specialist. METHODS: This was a prospective, multicenter cohort study in PWUD not enrolled in a centralized OAT program in a community-based facility in Limburg or OAT program in a community-based facility in Antwerp, Belgium, from October 2018 until October 2019. Two study teams recruited participants using an outreach method at 18 different locations. Participants were tested for HCV antibodies (Ab) by finger prick, and risk factors were assessed through a face-to-face questionnaire. Univariate analyses were used to assess the association between HCV Ab and each risk factor separately. A generalized linear mixed model was used to investigate the association between the different risk factors and HCV. RESULTS: In total, 425 PWUD were reached with a mean age of 41.6 ± 10.8, and 78.8% (335/425) were men. HCV Ab prevalence was 14.8% (63/425). Fifty-six (88.9%) PWUD were referred, of whom 37 (66.1%) were linked to care and tested for HCV RNA. Twenty-nine (78.4%) had a chronic HCV infection. Treatment was initiated in 17 (58.6%) patients. The adjusted odds for HCV Ab were highest in those with unstable housing 6 months before inclusion (p < .001, AOR 8.2 CI 95% 3.2-23.3) and in those who had ever shared paraphernalia for intravenous drug use (p < .001, AOR 6.2 CI 95% 2.5-16.0). CONCLUSIONS: An important part tested positive for HCV. Treatment could be started in more than half of the chronically infected referred and tested positive for HCV-RNA. Micro-elimination is necessary to achieve the World Health Organization goals by 2030. However, it remains crucial to screen and link a broader group of PWUD to care than to focus solely on those who inject drugs.

RESUMO

OBJECTIVES: The Belgian population of people living with HIV (PLHIV) has unrestricted access to direct-acting antiviral (DAA) treatment for hepatitis C virus (HCV) infection, since 2017. International literature claims that half of the patients remain untreated in high-income countries with unrestricted access to DAA. This study was initiated to provide an overview of the present situation in Belgium and recommendations for HCV care in PLHIV in other regions. METHODS: This was a retrospective, multicenter study of PLHIV in Belgium, from January 1, 2007 to December 31, 2018. The HCV cascade of care was examined. RESULTS: Out of 4607 unique PLHIV, 322 (7.0%) tested positive for HCV antibody and HCV RNA positivity was seen in 289 (6.3%). Of those with a proven HCV infection, 207/289 (71.6%) initiated treatment. Of the 171 (82.6%) persons with a sustained virologic response (SVR), 16 (9.4%) subjects were reinfected. CONCLUSIONS: We present a care cascade of 4607 PLHIV in Belgium. Treatment initiation and SVR rates were high compared to other regions. Implementation of a national HCV register to track progress and yearly screening, especially in PLHIV with high-risk behavior, remains crucial. Identifying reasons for not initiating treatment is necessary to achieve elimination of HCV in PLHIV by 2030.
