Chronic hepatitis C virus (HCV) infection can be associated with neuropsychiatric symptoms like fatigue and cognitive impairment, independent of the liver status. The present study aims to assess changes in the pattern and extent of neuropsychological symptoms after successful treatment with interferon (IFN)-based and IFN-free therapy. HCV-infected patients who underwent neuropsychological assessment in previous studies were invited to a follow-up examination. Patients were grouped according to the treatment status: Sustained virological response (SVR) after IFN treatment (IFN SVR, n = 14) or after therapy with direct acting antivirals (DAA SVR, n = 28) or ongoing HCV infection (HCV RNA+, n = 11). A group of 33 healthy controls served as reference. Patients completed self-report questionnaires addressing health-related quality of life (HRQoL), mood and sleep quality and a neuropsychological test battery including tests of memory and attention (Luria's list of words, PSE test, cancelling “d” test, Word–Figure–Memory Test and computer-based test battery for the assessment of attention [TAP]). At baseline, all three patient groups had worse fatigue, depression, anxiety and HRQoL scores compared to healthy controls. Longitudinal analysis revealed that fatigue and mood slightly improved in all patient groups over time, while HRQoL improved in SVR patients but not in HCV RNA+ patients. Memory test results improved significantly in all patient groups, irrespective of their virological status. In contrast, the attention test results showed no clear change from baseline to follow-up. Our data can be considered as a hint that HCV eradication—independent of therapy regimen—does not substantially ameliorate neuropsychiatric symptoms in HCV-afflicted patients.

The year 2024 is the year of new clinical practice and management guidelines for chronic hepatitis B virus (HBV) infection. World Health Organization (WHO) published the updated HBV guidelines in March 2024. In contrast, two key international societies for liver diseases, including the American Association for the Study of Liver Diseases (AASLD) and the European Association for the Study of the Liver (EASL), are currently in the process of updating their clinical practice guidelines for HBV. In 2022, China published their HBV guidelines, regarded as one of the most uncompromising ones as the threshold to start antiviral treatment is set at detectable HBV DNA above 10–20 IU/mL. In this chapter, the latest developments in the HBV guidelines with a specific focus on the Chinese & WHO guidelines are discussed. Specifically, the pros and cons of lowering treatment thresholds and the benefits of treating more people to avoid the complications of chronic hepatitis B, specifically HCC, are reviewed.

Despite the availability of effective treatment and vaccines for hepatitis B virus (HBV) and C virus (HCV), many people are still infected and remain unaware of their infection. The Camden and Islington Viral Hepatitis Identification Tool (CIVHIT), a computer-based search tool, was introduced in 60 general practices (GPs) in April 2014 to support identification, testing and treatment of individuals at high risk for blood-borne viruses (BBVs). CIVHIT searched electronic medical records (EMRs), flagging all those with codes linked to risk factors or medical conditions associated with BBVs. CIVHIT was associated with a 78.5% increase in BBV tests in primary care in both boroughs. This translated to a 55.8% rise in new diagnoses. HBV testing saw the largest increase resulting in twice as many people diagnosed. Only 23.2% of HBV and 14.9% of HCV-positive tests were referred to secondary care. In an index practice, the most common flag was a history of STIs (477/719, 66.3%). Individuals with previous or current drug use and those with a known hepatitis contact were more likely to be offered a test compared to those flagged due to a history of STI. HIV and HBV testing was lower in males following a test offer. There was an increased likelihood of testing for HBV and HCV with increasing age. Additionally, individuals with previous or current drug use and individuals with a known hepatitis contact were more likely to test for HCV compared to individuals flagged due to STI history. CIVHIT shows promise to assist with the elimination of BBVs.

Meeting the World Health Organisation 2030 target of treating 80% of people with hepatitis C virus (HCV) in Australia requires accessible testing and treatment services for at-risk populations. Previous clinical trials, including those in Australia, have demonstrated the efficacy of outreach programmes to community pharmacies offering opioid agonist therapy (OAT). This analysis evaluates the potential cost-effectiveness of introducing an outreach programme in community pharmacies. Using a decision analytic model, we estimated the impact of adding a temporary hepatitis C outreach and treatment programme in community pharmacies to the standard treatment pathway available through general practice. We compared the expected number of tests, diagnoses, cures and costs occurring through the addition of this outreach and treatment programme to those expected through general practice alone over a 12-month time horizon. We examined costs from the perspective of the health system and conducted one-way and probabilistic sensitivity analyses to assess uncertainty in model parameters and test key assumptions. In the model adding the outreach programme pathway increased the number of tests from 4178 to 8737, the number of diagnoses from 615 to 1285 and the number of cures from 223 to 777 among people on OAT over a 12-month period. Each additional cure achieved through the addition of the outreach programme was estimated to incur $48,964 (AUD 2023) to the health system, with > 85% of these costs attributable to medication and dispensing expenses. The average cost per cure was estimated to be $49,152 through routine care and $49,018 in the outreach programme. Although outreach models of care incur large upfront costs, they can capture otherwise unreached populations and result in comparable or favourable cost per cure, due to higher levels of engagement and lower rates of loss to follow-up.

Models estimate that the United States will not meet its 2030 hepatitis C virus (HCV) elimination goal. Engagement of healthcare providers including pharmacists is critical for HCV elimination efforts. We aimed to characterise the involvement of pharmacists in HCV management. The study design was a cross-sectional survey. Investigators sent the questionnaire to pharmacy and HCV organisations' listservs and limited responses to licensed pharmacists with direct patient care. Questions assessed setting, HCV screening, prescribing, and management; and opinions, and perceived barriers and facilitators to pharmacists' HCV management. Two hundred and nine survey respondents across 45 states reported managing 24 patients/month, with 5.3 (±4.4) years' experience in HCV, and identified pharmacist-managed HCV at their site since 2013 (±5.8 years). Most practice at academic medical centres (29%, 58/203) under collaborative practice agreements (67%, 127/189), as ambulatory care pharmacists (70%, 131/187), in primary care (50%, 65/131). Many pharmacists provide screening, linkage to care, and/or referral (81%, 157/194); 99.5% (190/191) perform treatment evaluation and selection; 98% (180/183) provide treatment education, 93% (171/183) initiate treatment, and 90% (162/180) provide on- and/or post-treatment monitoring. Respondents indicated collaboration with prescribers as most helpful in their role in HCV management, whereas lack of reimbursement was a main barrier. Satisfying components include HCV cure, care and education provision; frustrations include socioeconomic factors impeding patients' follow-up and prior authorisations/insurance barriers. Survey results show the variety of pharmacists' roles in direct HCV patient care and may be used to increase other providers' awareness of pharmacists' services and contributions to HCV elimination efforts.

International guidelines suggest cessation of nucleos(t)ide analogues (NA) independent of HBsAg loss in HBeAg-negative patients after 2–3 years of viral suppression. Detectable HBV-RNA levels at the time of NA cessation were linked to a better prediction of relapse after NA withdrawal in small cohorts of HBeAg-negative patients. This study proves the impact of HBV-RNA levels in the prediction of relapse in a large cohort of HBeAg-negative patients, mainly infected with genotype B or C. Serum levels of HBV-RNA, HBsAg, anti-HBc and HBcrAg were determined before NA withdrawal in 154 HBeAg-negative patients, participating either in a therapeutic vaccination trial (NCT02249988) or in an observational register trial (NCT03643172). Importantly, vaccination showed no impact on relapse. Endpoints of the study were virological relapse (HBV-DNA > 2000 IU/mL) or biochemical relapse (attendant ALT levels ≥ 2 × ULN) 24 weeks after NA cessation. Virological relapse occurred in 54.5% of patients (N = 84/154), including eight patients (10%) developing an ALT flare. Baseline HBV-RNA level did not differ significantly between relapsers and off-treatment responders (p = 0.92). No significant difference occurred in proportions of detectable HBV-RNA levels between off-treatment responders (N = 27/70; 38.6%) and relapsers (N = 31/84; 36.9%) (p = 0.99). Combining predefined HBsAg cut-offs (100 IU/mL, p = 0.0013), anti-HBc cut-offs (325 IU/mL, p = 0.0117) or HBcrAg cut-offs (2 log U/mL, p = 0.66) with undetectable HBV-RNA (HBsAg, p = 0.0057; anti-HBc, p = 0.085; HBcrAg, p = 0.60) did not improve relapse prediction. The value of HBV-RNA levels at timepoint of NA cessation for the prediction of relapse is limited in HBeAg-negative patients.
