Elimination of HCV infection as a public health concern by the end of this decade will require a concerted effort in all target populations, including drug-users in the inner-city. Several strategies have been proposed to identify, engage and provide HCV-infected residents with antiviral therapy and maximise treatment and cure achievement. This study aims to assess the effectiveness of a multidisciplinary approach in delivering HCV treatment to people who inject drugs (PWID) within Vancouver's inner city. We have evaluated a novel approach, the Community Pop-Up Clinic, for its ability to promote access to care and uptake of HCV therapy, with additional analyses of HCV reinfection and opioid-related mortality. From January 2021 to August 2023, we evaluated 1968 individuals. 620 (31.5%) were found to carry HCV antibodies and of these, 474 (76.5%) were found to be viremic. Treatment engagement has been secured in 387 (81.6%). 326 (84.2%) have started treatment, 60 in the pre-treatment phase and 1 died of an overdose in pre-treatment. Of 326, 302 completed treatments, 18 are currently on treatment and 1 died of an overdose. Of 302 who completed treatment, 286 confirmed as cured (SVR 12), 16 are awaiting SVR 4, 2 had documented virologic relapse and 1 was reinfected. Three patients withdrew from treatment. By mITT, the cure rate is 286/288 (99.3%). We documented 2 overdose deaths over 326 PY. The data presented validates multidisciplinary programs such as ours aimed at treating HCV in inner-cities and highlights societal benefits that could be achieved including lower overdose death rates.

Estimates of chronic hepatitis B virus (HBV) prevalence and critically the amount of infection that is undiagnosed or unlinked to care are uncertain—even in countries like UK where vertical transmission and overall prevalence are very low. In the absence of country of birth data, we aim to estimate HBV prevalence through combining public health surveillance data on antenatally screened women by ethnic group and multipliers generated from non-antenatally screened populations by ethnic group with English population denominators. Of 714,287 women aged 16–49 years with ethnic group data tested as part of antenatal care between 2015 and 2021, 4174 (0.6%) were HBsAg-positive; 94% in people of ethnic groups other than White British. Of 1,447,467 people tested for HBsAg with ethnic group data from other testing sources (primary and secondary care excluding occupational health and renal services), 27,628 (1.9%) were HBsAg-positive; 87% in people of ethnic groups other than White British. We estimate that the overall number and prevalence of people with chronic hepatitis B in England is 268,767 (95% CI: 227,896–314,044) and 0.58% (95% CI: 0.50–0.68). Approximately two-thirds were male, one-third female, and 68% were aged under 50. We estimate that over 83% of HBV infections are in people of ethnic groups other than White British, with 23% in people from Black ethnic groups, 21% from other White ethnic groups and 19% in Asian ethnic groups. These estimates are the first step towards establishing whether England can meet World Health Organisation targets to eliminate HBV as a public health problem—using methods that can also be used by other countries.

This multicentre study investigated the dynamics of thrombospondin 2 (TSP2) levels during direct-acting antiviral (DAA) therapy in hepatitis C virus (HCV) infected patients and evaluated TSP2's potential as a predictive marker for hepatocellular carcinoma (HCC). All 134 participants achieved sustained virological response at 12 weeks (SVR12) with DAA therapy, and serum TSP2 levels significantly decreased from before and after treatment (p < 0.001). During the median follow-up period of 6.0 years, HCC after DAA therapy was observed in 16 patients (11.9%). Patients with serum TSP2 High (≥ 32 ng/mL) at SVR12 had a significantly higher cumulative occurrence of HCC than did those without (26.5% vs. 7.0%, p = 0.0033). A multivariate Cox proportional hazards model identified male gender (HR 4.84, p = 0.005), HCC history (HR 4.61, p = 0.017) and TSP2 High (HR 3.93, p = 0.009) as significant independent predictors of HCC occurrence after DAA therapy. The model had a high concordance index of 0.878. Additionally, combining TSP2 High and FIB-4 High (≥ 3.538) at SVR12 yielded high specificity and negative predictive value (0.941 and 0.917, respectively) for predicting HCC. Kaplan–Meier analysis showed a higher HCC incidence in the TSP2 High + FIB-4 High group (log-rank p < 0.0001). In conclusion, TSP2 may be a promising biomarker for personalised HCC surveillance in DAA-treated hepatitis C patients.

Exposure to healthcare procedures might be a source of hepatitis C virus (HCV) transmission in Georgia, one of the few countries currently on track to eliminate hepatitis C. While there has been a history of iatrogenic transmission of HCV, the risk of HCV transmission related to endoscopic procedures has not been previously assessed in Georgia. The goal of this study was to assess HCV seroconversion among individuals undergoing endoscopic procedures to estimate the relative role and incidence of HCV infection attributable to endoscopic procedures. A prospective cohort study was conducted in four endoscopy units in two cities (Tbilisi and Kutaisi) of Georgia during April–September, 2021. Recruitment of study participants was conducted using convenience sampling, and every eligible patient was approached and invited to participate in the study. Study population included adults (age ≥ 18 years) who received an endoscopic procedure (gastroscopy, colonoscopy and bronchoscopy) in inpatient or outpatient unit at the study sites. HCV antibody (anti-HCV) testing was conducted using rapid diagnostic test (RDT) on the same day they underwent the endoscopic procedure. Patients with a non-reactive anti-HCV baseline test were retested after 6 months. Patients with reactive baseline tests were excluded from the study and linked to further testing and care. Participants with a reactive result on follow-up RDTs were retested using a lab-based anti-HCV and HCV ribonucleic acid (RNA) test. A total of 981 HCV antibody non-reactive participants were enrolled; 590 (64.8%) of them were reached and retested after 6 months. At retesting, two out of 590 (0.3%) individuals had a reactive anti-HCV result on RDT and both were negative on laboratory-based anti-HCV and HCV RNA tests. Based on the results of this study, endoscopic procedures were not shown to contribute to HCV transmission in Georgia.

A nationwide serosurvey among adults in 2021 showed a 2.7% (95% confidence interval [CI]: 2.3%–3.4%) prevalence of hepatitis B. Our analysis evaluates knowledge, attitudes and practices (KAP) for hepatitis B virus (HBV) infection among primary healthcare physicians (PHPs) in Georgia. We randomly selected 550 PHPs from medical facilities in Georgia's six largest cities. Using bivariate ordinal regression, we assessed the association of socio-demographic factors with an ordinal knowledge score (low/middle/high). Multivariable logistic regression was performed to calculate adjusted odds ratios (aOR) and 95% CI to determine associations between HBV knowledge score and practices. Of 550 selected PHPs, 506 (92.0%) agreed to participate. Among them, 62.8% scored in the medium or high knowledge tertiles, 72.7% were confident in diagnosing HBV infection, 37.3% were confident in managing patients with hepatitis B; 47.4% reported being screened for and 26.2% reported being vaccinated against HBV infection. Compared to those with low knowledge scores, PHPs with a high score were less likely to recommend activities not supported by evidence, such as: the use of ‘hepatoprotective’ medications (aOR 0.43, 95% CI 0.25–0.73), caesarean sections (aOR 0.47, 95% CI 0.27–0.82) and withholding breastfeeding (aOR 0.57, 95% CI 0.34–0.96) to prevent HBV transmission. The majority of PHPs were confident in diagnosing HBV infection, but only one in three were confident in managing patients with hepatitis B. PHPs with higher HBV knowledge were less likely to provide inaccurate instructions to their patients. These findings will help to develop awareness and education campaigns supporting HBV elimination in Georgia.

Screening for hepatitis D virus (HDV) is recommended for all individuals with hepatitis B virus (HBV) infection. Coinfected individuals experience more severe liver-related outcomes. We determined the HDV testing and coinfection rates and all-cause mortality among those infected with HBV. We used the US Department of Veterans Affairs (VA) healthcare system's national databases to identify individuals with HBV infection. We determined the proportion of individuals referred to gastroenterologists/hepatologists, or infectious diseases providers, and the proportion screened and tested positive for HDV. We calculated the HBV treatment rates, defined as ≥ 3 months of continuous prescription with an approved drug. Finally, we calculated all-cause mortality stratified by HDV coinfection and HBV treatment status. Among 44,951 individuals with at least one positive HBsAg, HBeAg or HBV DNA test, 5964 (13.3%) were screened for HDV (180 [3.0%] tested positive), and 28,291 (62.9%) were referred to gastroenterology/hepatology or infectious diseases. Treatment for HBV was prescribed for 73 (40.5%) of HDV-coinfected and 2425 (41.9%) HDV-uninfected individuals. All-cause mortality rate per 100 person-years was lower among those without HDV coinfection (2.98 for untreated HBV, 2.53 for treated HBV; p < 0.001) compared with those with HDV coinfection (5.14 for untreated HBV, 3.0 for treated HBV; p = 0.02). Kaplan–Meier curves demonstrated a significantly higher mortality among HDV-coinfected individuals who were not treated for HBV (log-rank p < 0.0001). Screening rates for HDV among HBV-infected individuals are suboptimal. While HDV coinfection is associated with higher all-cause mortality, HBV treatment may confer a survival benefit.

Hepatitis C virus (HCV) infection is a major public health burden in China, affecting more than 10 million individuals. We aimed to evaluate the effectiveness of a hospital-based intervention programme for HCV Surveillance with linkage to care (HEAL) in a prospective cohort. The HEAL programme was carried out targeting inpatients from non-infectious departments of two tertiary hospitals in Jiangsu, China. It consisted of an educational campaign to raise awareness of physicians from non-IDs to promote HCV surveillance, a patient-navigator-centred clinical algorithm responsible for the efficient follow-up of patients with positive HCV antibody, including comprehensive testing, diagnosis and treatment. We characterised the rate of linkage to HCV diagnosis, care and treatment during the pre-intervention period (from 1 July 2016 and June 30, 2018) and after the intervention (from March 2019 to May 2021). During the pre-intervention period, 89,303 (45.3%) out of 196,780 non-ID inpatients were screened for anti-HCV, and 631 patients were tested positive. One hundred and fifty-six (24.7%) patients was followed up for HCV RNA confirmatory testing, and 58 (37.1%) of patients further were diagnosed with chronic HCV infection (CHC). Only 18 (31.3%) of the diagnosed patients with CHC were linked to hepatitis C clinics for treatment, 10 (55.6%) patients received antiviral regimen. Among them, two (11.1%) received DAA treatment, while eight (44.4%) adopted peginterferon/ribavirin regimen. During the intervention period, 232,275 patients were hospitalised in non-infectious department and 151,203 (65.1%) were screened for anti-HCV. Of these, 960 patients tested positive for HCV antibodies, resulting in a prevalence of anti-HCV positivity of 0.63%. Six hundred and seventy (69.8%) patients were enrolled, and 100% were followed up for HCV RNA confirmatory testing. Two hundred and ninety-one (43.4%) individuals with active HCV were identified. Two hundred and thirty-eight (81.8%) of HCV-infected individuals were linked to HCV care, and 157 (65.9%) were linked to treatment. Compared to the pre-intervention period, there was a 2.61-fold increase in the percentage of patients linked to care and a 5.94-fold increase in the proportion of patients who started DAAs therapy. This HEAL programme achieved enhanced HCV Surveillance with linkage to care, which has been demonstrated as an effective strategy in the hospital setting to improve the hepatitis C care continuum by identifying inpatients unaware of their HCV status and facilitating their access to HCV treatment.

We aimed to evaluate the effectiveness of a hospital-based intervention programme for HCV Surveillance with linkage to care (HEAL) in a prospective cohort. The HEAL programme was carried out targeting inpatients from non-infectious departments of two tertiary hospitals in Jiangsu, China. It consisted of an educational campaign to raise awareness of physicians from non-IDs to promote HCV surveillance, a patient-navigator-centred clinical algorithm responsible for the efficient follow-up of patients with positive HCV antibody, including comprehensive testing, diagnosis and treatment. We characterised the rate of linkage to HCV diagnosis, care and treatment during the pre-intervention period (from 1 July 2016 and June 30, 2018) and after the intervention (from March 2019 to May 2021). During the pre-intervention period, 89,303 (45.3%) out of 196,780 non-ID inpatients were screened for anti-HCV, and 631 patients were tested positive. One hundred and fifty-six (24.7%) patients was followed up for HCV RNA confirmatory testing, and 58 (37.1%) of patients further were diagnosed with chronic HCV infection (CHC). Only 18 (31.3%) of the diagnosed patients with CHC were linked to hepatitis C clinics for treatment, 10 (55.6%) patients received antiviral regimen. Among them, two (11.1%) received DAA treatment, while eight (44.4%) adopted peginterferon/ribavirin regimen. During the intervention period, 232,275 patients were hospitalised in non-infectious department and 151,203 (65.1%) were screened for anti-HCV. Of these, 960 patients tested positive for HCV antibodies, resulting in a prevalence of anti-HCV positivity of 0.63%. Six hundred and seventy (69.8%) patients were enrolled, and 100% were followed up for HCV RNA confirmatory testing. Two hundred and ninety-one (43.4%) individuals with active HCV were identified. Two hundred and thirty-eight (81.8%) of HCV-infected individuals were linked to HCV care, and 157 (65.9%) were linked to treatment. Compared to the pre-intervention period, there was a 2.61-fold increase in the percentage of patients linked to care and a 5.94-fold increase in the proportion of patients who started DAAs therapy.

Acute hepatitis E virus infection is a serious global health problem, which a significant cause of morbidity and mortality. The aim of the present study was to characterise the clinical features and therapeutic response of patients with acute HEV infection and identify risk factors for poor prognosis. In a retrospective study from 01 January 2014 to 01 Januray 2022, we collected baseline data from all patients eligible for acute hepatitis E virus (HEV) infection and followed up with all patients via interviews and medical records. We explored the clinical feature of Chinese patients with acute HEV infection. The follow-up data of patients were used to identify risk factors for poor prognosis. In total, 628 acute hepatitis E (AHE) patients fulfilled the inclusion criteria and did not meet the exclusion criteria. Among them, 452 were males and 176 were females (M:F = 2.57:1). The median age at diagnosis was 57.0 years (interquartile range: 46–64 years). The median baseline serum levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), and total bilirubin (TBIL) were elevated in this cohort (642.3 U/L, 216.2 U/L, 104.1 μmol/L, respectively). The median hospitalisation duration was 16 days. Compared with patients without other liver diseases, patients with liver cirrhosis show lower baseline ALT and AST level, poorer coagulation indices and higher MELD scores. According to multivariate analysis, liver cirrhosis, high MELD score, low albumin concentration was found to be independent predictors of poor prognosis in patients with AHE. Our study used a lager sample size to validate that some demographic and serological features were quite different between patients with/without CLDs. Liver cirrhosis was a significant independent predictor of poor prognosis in acute HEV hepatitis.

Low-level viraemia (LLV) occurs in chronic hepatitis B (CHB) patients despite antiviral treatment, which may cause failed histological regression. Our study aimed to investigate the impact of different LLV types on fibrosis regression. The prospective study enrolled CHB patients with paired liver biopsies before and after 260 weeks of entecavir treatment. Fibrosis regression was defined by the Ishak score or P-I-R system. Patients were grouped as the SVR (HBV DNA < 20 IU/mL persistently) or LLV (HBV DNA between 20 and 2000 IU/mL), which were further grouped as very low-level viraemia (VLLV, HBV DNA < 50 IU/mL), occasionally LLV (OLLV, HBV DNA ≥ 50 IU/mL only once) and multiple LLV (MLLV, HBV DNA ≥ 50 IU/mL more than once). Logistic regression models were used to calculate the adjusted odds ratios (aORs) and 95% confidence intervals (CIs). The analysis included 111 CHB patients. In the SVR group (n = 54), 39 (72.2%) patients had fibrosis regression, which was higher than the LLV (56.1%, p = 0.080). The fibrosis regression rates for VLLV (30 patients), OLLV (17 patients) and MLLV (10 patients) were 70.0%, 52.9% and 30.0%, respectively. Compared with SVR, VLLV (aOR = 0.78; 95% CI: 0.28–2.21; p = 0.644) was not associated with fibrosis regression, but patients with non-VLLV (aOR = 0.27; 95% CI: 0.09–0.85; p = 0.025), especially with MLLV (aOR = 0.19; 95% CI: 0.04–0.97; p = 0.046) is significantly associated with hindered fibrosis regression. Our study suggests that patients with detectable serum HBV DNA levels higher than 50 IU/mL need to be monitored carefully, especially in those with more than once.
