Summary: Background/Aims: With polarizing income disparities, this study investigated the prevalence and trends of liver disease in a U.S. population‐based sample based on income‐to‐poverty ratio (IPR). Methods: This cross‐sectional study analysed survey data from the 1999–2018 National Health and Nutrition Examination Survey with highest (HIG), middle‐income (MIG), and lowest income (LIG) groups defined as IPR ≤ 1, 1 < IPR <5, and IPR ≥ 5, respectively. Results: We analysed 59,204 adult participants with 48.2% male, 39.7% aged 18–39, 36.2% 40–59, and 24.1% ≥60 years. The weighted prevalence of hepatitis C (HCV), B (HBV) infection, non‐alcoholic fatty liver disease (NAFLD), alcohol‐associated liver disease (ALD), and advanced fibrosis in LIG were 3.9% (n = 276), 7.4% (n = 527), 33.2% (n = 714), 5.2% (n = 401), and 9.0% (n = 694), respectively, compared to lower rates for HIG: 1.0% (n = 82), 3.2% (n = 263), 29.6% (n = 798), 3.9% (n = 354), and 5.0% (n = 638). After adjusting for age, sex, race and ethnicity, education, and birthplace, HIG had the lowest odds of having any liver disease [adjusted odds ratio (aOR) 0.67, p < 0.0001], with similar findings for specific conditions including HCV, HBV, and advanced fibrosis (aOR 0.24, 0.52, and 0.64, all p < 0.0001, respectively). While viraemic HCV prevalence decreased over time for HIG, there were no changes for MIG nor LIG. Similarly, NAFLD prevalence was stable for HIG but increased for MIG and LIG. Conclusion: LIG and MIG in the United States have higher liver disease burdens than HIG, with increasing NAFLD prevalence and lack of decline in current HCV infection prevalence over time as opposed to declining or stable trend in HIG.

Summary: Background: The WHO has set a goal to decrease viral hepatitis‐related fatalities by 65% by 2030. Aims: To locate and retrieve to care all individuals diagnosed with hepatitis B, D or C, and investigate why they were not linked to appropriate medical management. Methods: We conducted a retrospective‐prospective search for patients with hepatitis B, D or C virus (HBV, HDV and HCV) infection in the central laboratory database of the Barcelona northern health area (catchment population, 450,000). We reviewed records and contacted candidates for retrieval who were offered a specialist medical visit. Results: We reviewed records of 3731 patients with viral hepatitis (January 2019–December 2022): 1763 HBsAg+, 69 anti‐HDV+ and 1899 HCV‐RNA+. Among these, 644 (37%) HBV, 20 (29%) HDV and 1116 (56%) HCV patients were not currently linked to care. The proportion of patients receiving appropriate care was higher in HBV and HDV (p < 0.0001), and a higher percentage of unlinked hepatitis C patients had low life expectancy/comorbidities (39%; p < 0.0001). After implementing the linkage strategy, 254 HBV, 16 HDV and 54 HCV patients were successfully reintegrated into care. Among 1780 patients requiring linkage, 638 (35.8%) had moved to another health area or were missing essential contact data. Conclusions: Among patients with viral hepatitis who required appropriate specialist care and were eligible for contact, 64% with HBV, 100% with HDV and 27% with HCV were successfully reintegrated into care. Overall, 324 (47.2%) eligible patients were linked to care, indicating the success of this strategy. [ABSTRACT FROM AUTHOR]

The opioid epidemic has had a strong impact on West Virginia, due to various social, economic, cultural, and environmental hardships. To aid users, Needle Exchange Programs (NEPs) were created to exchange used needles for new sterile ones and provide awareness of treatment and rehabilitation options. This study aimed to assess the effectiveness of NEPs in reducing HIV and Hepatitis C infections in West Virginia, and the subsequent decrease in healthcare costs. In 2018 and 2019, there was an HIV outbreak in Cabell County, with 85 cases requiring CDC intervention in 2019. This occurred after the county-run needle exchange was reduced. Kanawha County also shut down its NEPs in 2018, followed by another HIV outbreak between 1 January 2019 and 13 March 2021, with 65 people testing positive for HIV linked to injection drug use, which required CDC intervention. To rehabilitate the opioid addict population, research on relapse, quality of life, social inclusion, stable housing, habilitation, and treatment adherence should be conducted. Policymakers should also revise existing policies surrounding the provision of harm reduction services to document adequate procedures for SSP procedures. This research suggests that suspending and scaling down NEPs in West Virginia has increased HIV/HCV incidence. [ABSTRACT FROM AUTHOR]

Background and Aims: The impact of hepatitis C virus (HCV) eradication via direct‐acting antiviral (DAA) therapy on overall mortality, particularly non‐liver‐related mortality, is understudied. Methods: We recruited 4180 patients with chronic HCV infection who achieved sustained virological response (SVR) (HCV eradication) through DAA therapy (n = 2501, SVR group) or who did not receive antiviral therapy (n = 1679, non‐SVR group); 1236 from each group were chosen using propensity score matching. Causes of death and all‐cause mortality, including non‐liver‐related diseases, were investigated. Results: Of the 4180 patients, 592 died during the follow‐up period. In the SVR group, the mortality rates from liver‐related and non‐liver‐related diseases were 16.5% and 83.5%, respectively. Compared to the non‐SVR group, mortality rates from liver‐related and non‐liver‐related diseases were 50.1% and 49.9%, respectively (p <.001). In non‐cirrhotic patients, multivariable analysis revealed that SVR was an independent factor associated with both liver‐related (hazard ratio [HR],.251; 95% confidence interval [CI],.092–.686) and non‐liver‐related (HR,.641; 95% CI,.415–.990) mortalities. In cirrhotic patients, multivariable analysis revealed that SVR remained an independent factor significantly associated with liver‐related mortality (HR,.151; 95% CI,.081–.279). In propensity score‐matched patients, the eradication of HCV (SVR group) decreased both liver‐related (p <.001) and non‐liver‐related mortality (p =.008) rates compared to persistent HCV infection (non‐SVR group). Conclusions: The elimination of HCV via DAA therapy reduced not only liver‐related mortality but also non‐liver‐related mortality in patients with chronic HCV. [ABSTRACT FROM AUTHOR]

Hepatitis E virus (HEV) is typically asymptomatic in developed countries but can be more severe in certain populations. We aim to describe the epidemiology of HEV‐associated hospitalisations from 1998 to 2020 in the United States, investigate risk factors for inpatient mortality and describe outcomes in pregnant women. We utilised the National Inpatient Sample and extracted cases of HEV‐associated hospitalisations using ICD‐9/10 diagnostic codes. Demographic, clinical and pregnancy data were extracted and analysed by chi‐square and logistic regression. We identified 3354 cases of HEV‐associated hospitalisations; 1689 (50.4%) were female and 1425 (42.5%) were non‐Hispanic White. The median age was 50 (IQR: 37–59) years. Hospitalisation rates for HEV ranged from 2.5 per 10,000,000 in 2008 to a peak of 9.6 per 10,000,000 people in the general U.S. population in 2004. The mortality rate was 5.2%. Age ≥ 40 years (OR: 7.73; 95% CI: 1.57–38.09; p = 0.012), HIV infection (OR: 4.63; 95% CI: 1.26–16.97; p = 0.021), and coagulopathy (OR: 7.22; 95% CI: 2.81–18.57; p < 0.001) were associated with increased odds of mortality within the HEV cohort. There were 226 pregnant women with HEV. Rates of maternal death, stillbirth and preterm birth were similar between HEV and non‐HEV pregnant cohorts. Hepatitis B and hepatitis C co‐infection were significantly more common in the HEV pregnant cohort (p < 0.05). HEV‐associated hospitalisations are uncommon in the United States, but likely underdiagnosed. Certain risk factors can be used to predict prognosis of these hospitalised patients. Pregnant women with HEV appear to have favourable maternal and fetal outcomes despite hepatitis B and C co‐infection. [ABSTRACT FROM AUTHOR]

It is critical to address hepatitis C virus (HCV) in carceral settings to achieve worldwide elimination of the virus. We describe New Mexico's (NM) experience expanding HCV treatment in state prisons, supplemented with Project ECHO (ECHO; virtual mentorship through guided practice) and the NM Peer Education Program (NMPEP). We describe how using these programs may be a model for expanding treatment in prisons globally. ECHO, NM Corrections Department (NMCD) and Wexford Health Services (WHS) collaborate to treat HCV in state prisons and increase HCV knowledge among incarcerated persons using NMPEP. Each person arriving in prison is tested for HCV and those with active infection receive baseline labs, which are reviewed. Patients not meeting criteria for simplified treatment are presented to ECHO for expert guidance. Otherwise, patients are treated by WHS without consultation. NMPEP provides patient‐to‐patient education in prisons, addressing HCV myths and exploring treatment refusals. From December 2020 to June 2023, 3603 people had HCV viremia. In this study, 1685 people started treatment: 1280 were treated using the simplified algorithm and 405 were presented to ECHO. Of the 988 people who completed treatment and had sustained virologic response (SVR) labs drawn, 89.2% achieved SVR (i.e., cure). Most of the 107 people who did not achieve SVR had presumed reinfection. NMPEP trained 148 peer educators who educated 3832 peers about HCV prevention and treatment. HCV treatment in prisons can be expanded by implementing simplified treatment algorithms, use of the ECHO model for patients with advanced disease and peer education. [ABSTRACT FROM AUTHOR]

The prevalence of mixed hepatitis C virus (HCV) genotype infection in a representative Canadian HCV cohort is reported and virological response with direct acting antiviral (DAA) treatment was evaluated. 3272 HCV‐positive participants were enrolled, of which 2945 (90.0%) initiated DAA therapy. 0.8% were identified with mixed genotype infection. Overall sustained virological response (SVR) was 99.1% and did not differ based on mixed genotype status. Any historical disadvantage to achieving cure with HCV treatment in mixed genotype infection has been overcome by current DAA regimens. [ABSTRACT FROM AUTHOR]

To date, the effectiveness of direct‐acting antivirals (DAAs) discontinued before 4 weeks has not been analysed in routine clinical practice. The study aimed to determine whether such a short therapy will enable achieving a sustained virological response under real‐world experience. The study population of 97 patients who discontinued DAA therapy and had data enabling analysis of patient and disease characteristics, and assessment of treatment effectiveness was selected from 16,815 patients registered in the EpiTer‐2 database. The most common reason for discontinuation was hepatic decompensation (20.6%) or the patient's personal decision (18.6%). Patients who discontinued treatment were significantly older, more frequently therapy‐experienced, more likely to have cirrhosis, a history of decompensation and a Child–Pugh B or C classification than those who completed treatment. SVR was achieved by 93.5% of patients who discontinued treatment after 4 weeks, 60.9% if discontinued at 3 or 4 week and 33.3% at Week 1 or 2. Patients receiving pangenotypic but not genotype‐specific treatment who discontinued after 4 weeks were as likely to achieve SVR as those who completed therapy. Patients who responded to treatment that lasted no longer than 2 weeks had a low baseline viral load (<400,000 IU/mL). Despite discontinuation of therapy after Week 4, the chances of SVR are high. Very early discontinuation does not preclude therapeutic success, especially in patients with low baseline viral load. [ABSTRACT FROM AUTHOR]

Pakistan harbours a large burden of hepatitis B virus (HBV) and hepatitis C virus (HCV) infection. We utilised repeat sero‐surveys to assess progress achieved towards hepatitis elimination in Pakistan. Multilevel logistic regression evaluated the change in HBV infection (HBV surface antigen (HBsAg)‐positive) prevalence and HCV exposure (HCV antibody (HCV‐Ab)‐positive) prevalence between two sero‐surveys from 2007 and 2019 for Sindh province and associated risk factors. Adjusted odds ratios (aORs) were estimated and population‐attributable fractions (PAF) for modifiable risk factors for HCV exposure. The 2007 and 2019 surveys included 8855 and 6672 individuals. HBsAg prevalence decreased from 2.6% (95% confidence intervals (95% CI): 2.2–2.9) in 2007 to 1.1% (95% CI: 0.8–1.3) in 2019, while HCV‐Ab prevalence increased from 5.1% (95% CI: 4.6%–5.5%) to 6.2% (95% CI: 5.6%–6.8%). The age and gender‐adjusted HBsAg prevalence decreased by 80% (aOR = 0.2, 95% CI: 0.1–0.4) among children and 60% (aOR = 0.4, 95% CI: 0.3–0.6) among adults over 2007–2019, while HCV‐Ab prevalence decreased by 60% (aOR = 0.4, 95%CI:0.2–0.7) in children and increased by 40% (aOR = 1.4, 95% CI: 1.2–1.7) in adults. HCV‐Ab prevalence was lower in adults with secondary (aOR = 0.6, 95% CI: 0.5–0.8) and higher (aOR = 0.5, 95%CI:0.3–0.8) education compared to illiterates and higher among adults reporting blood transfusion (aOR = 1.7, 95% CI: 1.2–2.4), family history of hepatitis (aOR = 2.5, 95% CI: 1.9–3.3), past year medical injection (aOR = 2.1, 95% CI: 1.6–2.7), being tattooed (aOR = 1.4, 95% CI: 1.0–1.9) and shaved by traditional barber (aOR = 1.2, 95% CI: 1.0–1.5). Modifiable risk factors accounted for 45% of HCV exposure, with medical injection(s) accounting for 38% (95%CI,25.7–48.4%). Overall HCV has increased over 2007–2019 in Sindh province, while HBV prevalence has decreased. Medical injections should be an important focus of prevention activities. [ABSTRACT FROM AUTHOR]

In 2023, the US Centers for Disease Control and Prevention recommended universal screening for hepatitis B virus (HBV); however, the proportion of US adults screened before implementing this recommendation is unknown. We analysed nationally representative data from the National Health Interview Survey (2013–2017) on self‐reported HBV testing among noninstitutionalized US adults ≥18 years. We employed Poisson logistic regression to identify factors associated with self‐reported testing, using a conceptual framework that included four overarching factors: sociodemographic characteristics, healthcare access, health‐seeking behaviours and experiences, and access to internet‐based health information. Among 149,628 survey respondents, the self‐reported HBV testing rate was 27.2% (95% CI 26.2–28.7) and increased by 1.7% from 2013 to 2017 (p =.006). In adjusted analysis, health‐seeking behaviours and experiences had the strongest associations of self‐reported testing including a history of hepatitis (AOR 2.68, 95% CI 1.92–3.73), receipt of hepatitis B vaccination (AOR 5.11, 95% CI 4.61–5.68) and prior testing for hepatitis C (AOR 9.14, 95% CI 7.97–10.48) and HIV (AOR 2.69, 95% CI 2.44–2.97). Other factors associated with testing included being male (AOR 1.14, 95% CI 1.03–1.26), ages 30–44 years (AOR 1.37, 95% CI 1.17–1.61), 45–60 years (AOR 1.55, 95% CI 1.30–1.80) and ≥60 years (AOR 1.53, 95% CI 1.28–1.84), residence in the Western US region (AOR 1.23, 95% CI 1.06–1.43), and access to internet‐based health information (AOR 1.32, 95% CI 1.18–1.47). Being Hispanic was associated with lower odds of testing (AOR 0.80, 95% CI 0.66–0.97). These findings may help guide optimal HBV screening in the universal testing era. [ABSTRACT FROM AUTHOR]

We evaluated the impact of implementing automated hepatitis C (HCV) opt-out screening in the emergency department of an urban, academic medical center with high HCV prevalence, in the context of a longstanding HCV opt-in screening model. We compared nine-month periods before and after implementation. HCV testing increased by 502%, and active HCV infection identification increased by 212%. Settings where there is great opportunity for HCV diagnosis, such as emergency department settings, should consider opt-out HCV screening models.

Aim: An ineffective immune response resulting from dysregulation of cytokine production might encourage viral persistence and cause chronic viral hepatitis to worsen. This study examined the relationship between alterations in interleukin-6 (IL-6) levels and the IL-6 − 174 G > C (rs1800795) polymorphism, as well as how this polymorphism affects the development and progression of chronic hepatitis brought on by hepatitis B (HBV) and hepatitis C (HCV) into hepatocellular carcinoma (HCC). Patients and methods: Whole blood samples from 126 Egyptian patients with HCC (111 with HCV and 15 with HBV), as well as 126 age- and sex-matched healthy individuals, were used to extract DNA. Using PCR-based allele-specific amplification (ASA), the existence of the IL-6 G-174C polymorphism was investigated. Additionally, each participant's serum IL-6 levels were determined using an enzyme-linked immunosorbent assay (ELISA). Results: The primary observations revealed that HCC patients had greater serum levels of IL-6 compared to the control groups (p < 0.001). Patients with the variant (CG and GG) genotype in the HCC group were found to have more disease severity indicated by higher levels of alpha-fetoprotein (AFP) and a higher ascites grade, as well as increased inflammatory activity as defined by higher levels of IL-6 and C-reactive protein (CRP) (p < 0.001 for both) in comparison to patients with the wild-type (CC) genotype (p < 0.001 and p = 0.002, respectively). Conclusion: The rs1800795 SNP in the IL-6 gene was associated with increased inflammatory activity and high levels of IL-6, indicating that this SNP may play a role in the development of HCC in Egyptian patients with chronic viral hepatitis.

Background: Chronic hepatitis C virus (CHC) infection represents a crucial health problem, especially among children and adolescents. The ledipasvir (LDV)/sofosbuvir (SOF) regimen has been approved to treat adolescents (aged 12 to 17 years old) infected with hepatitis C virus (HCV) genotypes 1, 4, 5, and 6 and then extended to include children above or equal to 3 years old. The current study aims to evaluate the safety and efficacy of SOF/LDV combination in treating CHC-infected 12- to 17-year-old adolescents. Patients and methods: This retrospective cohort study was performed on 147 Egyptian adolescents with CHC. The patients were treated with SOF 400 mg/LDV 90 mg combination once daily for 12 weeks. Possible side effects and laboratory data including HCV ribonucleic acid polymerase chain reaction (RNA PCR), complete blood count (CBC), and liver tests were recorded at baseline and week 12 after the end of treatment (EOT). Results: Sustained virological response 12 weeks (SVR12) after end of treatment (EOT) was observed in 146 out of 147 patients (99.3%). The treatment regimen was efficiently tolerated with no reported cases of discontinuation caused by intolerability. Moreover, the side effects were minimal; 71.4% of the patients did not report any side effects related to the treatment. However, the rest mentioned fatigue, headache, or both of them. Fatigue was the main side effect reported in 16.3% of the patients. Furthermore, ALT and AST levels were normalized after treatment. FIB-4 and APRI scores were statistically significantly decreased 2 years post-SVR, in comparison to their levels before treatment, from 0.34 and 0.36 to 0.25 and 0.17, respectively. Conclusion: The LDV/SOF regimen is one of the safe regimens used to treat adolescent patients with CHC infection. [ABSTRACT FROM AUTHOR]

Objectives: Cryoglobulinemia (CG) is marked by abnormal immunoglobulins (Ig) in serum, precipitating at temperatures below 37 °C. Current classification categorizes CG into three subtypes (types I, II, and III) based on Ig clonality. The features distinguishing patients with CG based on their etiology remain unidentified. Aiming to characterize clinical and serological profiles of CG individuals, we conducted an observational analysis of a large cohort of patients and compared their characteristics based on underlying causes: hepatovirus (HV) infections, rheumatic diseases (RD), hematological disorders, and unidentified etiology (essential CG). Methods: We analyzed 252 cryoglobulin-positive serum samples from 182 patients and classified these into the four etiological groups. A separate sub-analysis was carried out for 10 patients meeting criteria for multiple diseases. We collected demographic, clinical, and laboratory data: CG characterization, complement (C3 and C4) levels, antinuclear antibodies (ANA), and rheumatoid factor (RF). Kruskal–Wallis and Wilcoxon–Mann–Whitney U-tests were used for comparisons. Results: Most patients (93.3%) had mixed cryoglobulinemia (types II + III), with 6.7% having type I. HV infection, predominantly hepatitis C, was the main (52.9%) associated condition within the cohort, followed by rheumatic (27.3%) and hematological (9.8%) disorders. In our cohort, ANA were frequent (45.3%) and often associated with RF positivity (43.6%) and decreased complement levels (C3: 42.4%, C4: 32.5%). Essential CG and CG associated with RD had a higher prevalence of cutaneous manifestations (p < 0.01) and renal involvement (p = 0.017). Hematological disorder-related CG showed higher cryoglobulin and RF concentrations (p < 0.01), despite milder symptoms. Conclusions: Our study underscores a mixed prevalence of CG across disease subgroups, with hepatitis-C virus as the primary factor, followed by rheumatic and hematological disorders. Four clinical and serological profiles of CG were identified based on their etiologies. [ABSTRACT FROM AUTHOR]

Background: There are reported studies of Hepatitis C and chronic kidney disease association. However, how this liver virus infection affects the general population's susceptibility to the onset of the kidney disease is still unknown. Methods: To determine if a positive anti-HCV serologic status is linked to a greater incidence of chronic kidney disease in the general adult population, a systematic evaluation of the published medical literature since 2015 was conducted. A summary estimate of the relative risk of chronic kidney disease with HCV was produced using a random-effects model. Moreover, stratified analysis and meta-regression were performed. Results: Twelve studies (n = 605858 patients) were filtered and included. Meta-analyses were conducted according to the outcome. Pooling results of longitudinal studies (n = 06 studies, n = 347120 unique patients) demonstrated an association between positive anti-HCV serologic status and increased incidence of CKD. The summary estimate for adjusted hazard ratio was 1.21 with (95% confidence interval 1.13; 1.29, P = 0.001), and between studies heterogeneity was noted (P value by Q test < 0.001). In the subset of Asian surveys, the risk of the occurrence of chronic kidney disease linked to HCV was 1.70 (95% confidence interval 1.40; 2.00) without heterogeneity (P value by Q test = 0.6). Conclusions: We found a strong correlation between HCV infection and a higher risk of chronic renal disease in general global population. [ABSTRACT FROM AUTHOR]

Introduction: Cardiovascular pathologies represent the first cause of death in uremic patients and are among the leading causes of mortality in patients with hereditary angioedema due to C1-inhibitor deficiency (HAE-C1INH). Before 2020, the most common treatment for long-term prophylaxis in HAE-C1INH patients in Italy was attenuated androgen, which may increase cardiovascular risk by multiple mechanisms. Case description: We present a case report of a 56-year-old patient with HAEC1INH type I affected by IgA nephropathy with severe kidney impairment. The patient experienced a first kidney transplant and, after late rejection, underwent a second kidney transplant. Further comorbidities included obesity, hypertensive cardiomyopathy, HCV liver disease, and dyslipidemia. His prophylactic therapy to prevent angioedema attacks had consisted of attenuated androgens for about 40 years. Since 2020, new modern targeted therapy for LTP, particularly lanadelumab, has shown promising results. The majority of patients with attenuated androgens have been successfully switched to lanadelumab, including our patient. Since introducing lanadelumab (300 mg subcutaneously every two weeks; after a six-month attack-free period, the dosing interval of lanadelumab was extended to four weeks), the patient has not experienced any acute HAE attack and did not report any adverse events. Moreover, we observed decreased total cholesterol, C-LDL, and body mass index, reducing the Matsushita et al. score for ten years of cardiovascular risk from 13.2% to 9.3%. Conclusion: lanadelumab is effective and safe in preventing hereditary angioedema attacks, as well as in reducing cardiovascular risk in an immunosuppressed patient with significant comorbidities. The successful outcomes of this case highlight the potential of lanadelumab as a promising prophylactic therapy. [ABSTRACT FROM AUTHOR]

Background Illicitly manufactured fentanyl (IMF) increases overdose mortality, but its role in infectious disease transmission is unknown. We examined whether IMF use predicts hepatitis C virus (HCV) and human immunodeficiency virus (HIV) incidence among a cohort of people who inject drugs (PWID) in San Diego, California and Tijuana, Mexico. Methods PWID were recruited during 2020–2022, undergoing semi-annual interviewer-administered surveys and HIV and HCV serological rapid tests through 2024. Cox regression was conducted to examine predictors of seroconversion considering self-reported IMF use as a 6-month lagged, time-dependent covariate. Results Of 398 PWID at baseline, 67% resided in San Diego, 70% were male, median age was 43 years, 42% reported receptive needle sharing, and 25% reported using IMF. HCV incidence was 14.26 per 100 person-years (95% confidence interval [CI]: 11.49–17.02), and HIV incidence was 1.29 (95% CI:.49–2.10). IMF was associated with HCV seroconversion, with a univariable hazard ratio (HR) of 1.64 (95% CI: 1.09–2.40), and multivariable HR of 1.57 (95% CI: 1.03–2.40). The direction of the relationship with HIV was similar, albeit not significant (HR 2.39; 95% CI:.66–8.64). Conclusions We document a novel association between IMF and HCV seroconversion among PWID in Tijuana–San Diego. Few HIV seroconversions (n = 10) precluded our ability to assess if a similar relationship held for HIV. IMF's short half-life may destabilize PWID—increasing the need for repeat dosing and sharing smoking materials and syringes. New preventive care approaches may reduce HCV transmission in the fentanyl era. [ABSTRACT FROM AUTHOR]

Little is known regarding the relationship between common comorbidities in persons with tuberculosis (TB) (including human immunodeficiency virus [HIV], diabetes, and hepatitis C virus [HCV]) and post-TB mortality. We conducted a retrospective cohort study among persons who initiated treatment for rifampicin-resistant or multi/extensively drug-resistant (RR or M/XDR) TB reported to the country of Georgia's TB surveillance during 2009–2017. Exposures included HIV serologic status, diabetes, and HCV status. Our outcome was all-cause post-TB mortality determined by cross-validating vital status with Georgia's death registry through November 2019. We estimated adjusted hazard rate ratios (aHR) and 95% confidence intervals (CI) of post-TB mortality among participants with and without comorbidities using cause-specific hazard regressions. Among 1032 eligible participants, 34 (3.3%) died during treatment and 87 (8.7%) died post-TB treatment. The median time to post-TB death was 21 months (interquartile range 7–39) after TB treatment. After adjusting for confounders, the hazard rates of post-TB mortality were higher among participants with HIV co-infection (aHR = 3.74, 95%CI 1.77–7.91) compared to those without HIV co-infection. In our cohort, post-TB mortality occurred most commonly in the first 3 years post-TB treatment. Linkage to care for common TB comorbidities post-treatment may reduce post-TB mortality rates.

Moreover, we observed decreased total cholesterol, C-LDL, and body mass index, reducing the Matsushita et al. score for ten years of cardiovascular risk from 13.2% to 9.3%. Conclusion: lanadelumab is effective and safe in preventing hereditary angioedema attacks, as well as in reducing cardiovascular risk in an immunosuppressed patient with significant comorbidities. The successful outcomes of this case highlight the potential of lanadelumab as a promising prophylactic therapy. [ABSTRACT FROM AUTHOR]

The article provides an overview of different experimental approaches to studying virus cell-to-cell transmission in vitro and in vivo, focusing on examples such as chikungunya virus and HIV-1. The article describes various methods for investigating cell-to-cell transmission, including fluorescence and electron microscopy imaging, live cell imaging, and co-culture assays. The article also explores the potential of inhibiting cell-to-cell transmission as an antiviral strategy. [Extracted from the article]

Background: Communities living along the shoreline and on the islands of Lake Victoria in northwestern Tanzania remain endemic for schistosomiasis and suffer from the life-threatening morbidities associated with the disease. Nevertheless, the control measures particularly the mass drug administration do not cover the adult population. The current project on Ukerewe island aims to close this gap by involving adult community members in the control program. Here we report the baseline results of S. mansoni infection and associated hepatosplenic morbidities and factors before implementing the project activities. Methods: A cross-sectional analytical study was conducted with 4,043 participants aged ≥ 18 years living in 20 villages on Ukerewe island, northwestern Tanzania. Individual stool and urine samples were collected and examined using the Kato-Katz (KK) technique and point-of-care circulating cathodic antigen testing(POC-CCA) to identify S. mansoni eggs and antigens, respectively. All study participants underwent ultrasound evaluation of S. mansoni hepatosplenic morbidities using the Niamey protocol. Rapid diagnostic tests were used to diagnose HIV infection, hepatitis C and chronic hepatitis B. A questionnaire was used to collect demographic data and reported clinical symptoms of study participants. Results: A total of 4,043 participants took part in the study, of which 49.7% (n = 2,009) and 50.3% (n = 2,035) were male and female, respectively. The overall prevalence of S. mansoni infection was 30.4% (95%CI:29.0-31.9%) and 84.7% (95%CI:83.3–85.9%), respectively, based on the KK technique and the POC-CCA test. The geometrical mean eggs per gram of faeces (GMepg) was 105.3 (95%CI:98.7-112.3% GMepg) with 53.9%, 32.4% and 13.7% of the participants having mild, had moderate and severe intensity of infection. The prevalence of hepatitis C, HIV, and hepatitis B was 0.4%, 2.2% and 4.7%, with 0.2%, 2.2% and 5.4% of the infected individuals coexisting with S. mansoni infection. The prevalence of splenomegaly, periportal fibrosis, hepatomegaly, and portal vein dilatation was 40.5%(95%CI: 38.8–42.1%), 48.1%(95%CI:64.4–49.7%), 66.2%(95%CI:4.6–67.7%) and 67.7%(95%CI:66.2–69.2%), with their prevalence varying depending on the demographic information and infection status of the participants. Other detectable ultrasound-related morbidities included ascites (1.7%), collateral veins (18.3%) and gall bladder wall thickness (40.4%). Age groups, gender, reported clinical characteristics, reported non-use of the drug praziquantel, liver imaging pattern, and place of residence remained independently associated with hepatosplenic morbidities. Conclusion: The current study setting is endemic for S. mansoni infection and the population has a high prevalence of the disease associated hepatosplenic morbidities characterized by hepatomegaly, splenomegaly, ascites, gall bladder wall thickening, periportal fibrosis and portal vein dilatation. Several demographic, clinical and epidemiological circumstances remained independently associated with S. mansoni infection and associated morbidities. These findings call for integrative intervention efforts, starting with whole community MDA that includes all out of schools community members. [ABSTRACT FROM AUTHOR]

Since the discovery of hepatitis C virus (HCV) in 1989, we now have curative treatment options with direct-acting antiviral therapies. By increasing the rate of treatment and reducing transmission, the eradication of HCV is potentially achievable. Nonetheless, the feasibility and implementation of this goal remains challenging. This article sums up the approach to managing children with HCV in the Asia–Pacific region and lists some of the difficulties and complexities surrounding this issue. [ABSTRACT FROM AUTHOR]

The Hepatitis C Virus (HCV) is a significant public health challenge in European countries. Historically, healthcare-related procedures were the primary source of HCV infection in Europe. However, with the implementation of blood safety programs, injection drug use has become the main transmission route. The infection's distribution and genotype prevalence vary widely across the continent. Even with the availability of highly effective direct-acting antiviral (DAA) therapies, HCV infection is far from being controlled. A significant proportion of patients remain undiagnosed, contributing to the ongoing transmission of the virus. Additionally, several barriers hinder the widespread use of DAAs, including high treatment costs, stigma, poor linkage to care, and considerable geographical variations in prevalence and transmission routes. The World Health Organization has set ambitious targets to reduce liver-related deaths, decrease new viral hepatitis infections, and ensure that 90% of infected individuals are diagnosed by 2030. However, most European countries face challenges, highlighting the need for screening programs, funding mechanisms, and public health strategies to effectively control HCV infection in Europe.

Life-threatening events including terminal illness intensify the search for meaning and incite individuals to get closer to religion. Terminal patients can often find religious practices as helpful as medical therapy for bettering both physical and mental health. The present research aims to explain the interaction between religion, spirituality, and social support in coping with terminal illness among Muslim hepatitis C patients in Pakistan. A semi-structured open-ended interview guide was utilized to collect the data. Participants expressed that the deployment of religious and spiritual beliefs along with socio-emotional support during illness fostered medical therapy. Participants also revealed that belief in God provided them the strength to be steadfast during the terminal stage of the disease. Religious beliefs enabled terminal participants to accept death as an eventual reality and a normal part of their lives. Furthermore, participants put forward their longing for those kinds of religious practices that terminal diseases usually restrained them from receiving. The emotional support stemming from social relationships also improved resilience to cope with the terminal stage of illness. The study concludes that the interplay of religion, spirituality, and social support normalizes the fear of death, lessens pain, and improves resilience among Muslim hepatitis C patients in Pakistan.

Hepatitis C virus (HCV) is an important cause of chronic liver disease. Among at-risk populations, access to care is challenging. The French Ministry of Health has supported a seek-and-treat pilot intervention aiming at micro-elimination in Perpignan, France, to inform scale-up of elimination efforts across the whole territory. University College Dublin (UCD) led a successful EU funded project, called HepCare, focusing on the micro-elimination of HCV. UCD was contracted to evaluate and benchmark the Perpignan results against results from HepCare. Using mixed-method approaches including qualitative interviews with patients, a focus group with healthcare professionals, and quantitative analyses of the cascade of care against results obtained at other European sites, we analyse the acceptability, reproducibility, replicability, and effectiveness of the Perpignan intervention. A total of 960 participants were recruited in the Perpignan area. HCV antibody test results were obtained for 928 (96.6%), of which 150 (15.6%) were antibody-positive. Of the antibody-positive participants, 68 (45.3%) tested positive for HCV-RNA, 141 (94%) were linked to care, and of the HCV-RNA-positive participants, 60 (88%) started treatment. Of those who underwent treatment, 34 (56.7%) completed treatment and achieved a sustained viral response (SVR) at dataset closure, 18 (30%) were still in treatment, 5 (8.3%) defaulted from treatment, and 3 (5%) had a virologic failure or died. The intervention in Perpignan was acceptable to patients, but had limitations in effectiveness, as shown in comparisons with HepCare results. To engage harder-to-reach cohorts in France, future models of care in the territory should incorporate peer support. [ABSTRACT FROM AUTHOR]

Hepatitis B and Hepatitis C are viral causes of Hepatitis that lead to significant worldwide mortality and morbidity through the sequelae of fibrosis and hepatocellular carcinoma. In this review, we have summarized recent studies that have examined the effects of antiviral therapy on the regression of fibrosis and the reduction in mortalities associated with the viruses. Antiviral therapy significantly decreases mortality and induces the regression of fibrosis. [ABSTRACT FROM AUTHOR]

Background: In kidney transplantation, concerns have been raised regarding increased incidence of viral opportunistic infections in hepatitis C virus (HCV) nucleic acid test (NAT)‐negative (‐) recipients who received HCV NAT‐positive (+) donor kidneys, specifically BK polyomavirus (BKPyV), cytomegalovirus (CMV), and Epstein‐Barr virus (EBV). The purpose of this study was to determine the incidence of these three viral opportunistic infections in HCV NAT‐ recipients who have undergone kidney transplantation with HCV NAT+ donor kidneys at our institution. Methods: This was an Institutional Review Board‐approved, single‐center, retrospective case‐control study of HCV NAT‐ kidney transplant recipients with HCV NAT+ donors from 2018 to 2021. The primary outcome was the cumulative incidence of viral infections of BKPyV, CMV, and/or EBV within 1 year following kidney transplantation. Results: A total of 231 patients were included, 77 in the exposed (donor HCV NAT+) group and 154 in the control (donor HCV NAT‐) group. The adjusted cumulative incidence of viremia within 1 year did not statistically differ between groups (77% exposed group versus 66% for the control group, hazard ratio 1.34, 95% confidence interval 0.95–1.89). In addition, no statistically significant differences were observed for secondary outcomes with the exception of CMV viremia (62% exposed versus 49% control, p = 0.021). However, there were more patients in the exposed group at high risk for CMV viremia based on serostatus (CMV Donor+/Recipient‐, D+/R‐). Conclusion: Among patients who received HCV NAT+ donor kidneys, no clear association was observed between exposure to HCV NAT+ donor kidneys and viral infections of BKPyV, CMV, or EBV.

Prior research in the Santa Clara County (SCC) Jail showed that knowledge of hepatitis C virus (HCV), perception of risk, and perceived coercion impacted participation in routine HCV screening; however, the experiences of patients undergoing screening were not assessed. The purpose of the study was to understand patient perceptions of undergoing routine viral hepatitis screening and receiving a diagnosis of HCV while incarcerated. A qualitative design was employed using semi-structured interviews of individuals newly diagnosed with HCV via routine screening in the SCC Jail between March and November 2023. The data were analyzed using thematic analysis. Of the 15 participants, most were within the 35 to 44 (47%) and 25 to 34 (40%) age ranges, were White or Caucasian (47%), and all were male. Nine themes emerged: (1) risk perception as a motivator for testing, (2) testing convenience to maintain health, (3) minimal to no prior testing experience, (4) mixed experiences testing in the jail, (5) negative to neutral reactions to HCV diagnosis, (6) intrinsic motivation to get treated, (7) basic HCV knowledge after diagnosis, (8) seamless treatment experience in the jail, and (9) barriers to continuing care upon release. The HCV screening process, including disclosure, education, and treatment initiation, was positively received among participants. [ABSTRACT FROM AUTHOR]

Dried blood spot (DBS) sampling is increasingly used for hepatitis C virus (HCV) screening. HCVcAg testing offers a faster and more streamlined approach to diagnosing HCV infection. We conducted a systematic review and meta‐analysis to assess the diagnostic performance of the Abbott ARCHITECT HCV Ag assay for screening active HCV infection using DBS samples. Eight studies (n = 1229) were selected among all published studies available up to October 4, 2024, in different databases with a search strategy registered (PROSPERO: CRD42022363975). The gold standard method was the HCV PCR test. Data were analyzed using the MIDAS module in STATA with a random effects model. Combined diagnostic accuracy measures were as follows: sensitivity 85%, specificity 100%, positive likelihood ratio (PLR) 233.1, negative likelihood ratio (NLR) 0.15, and summary receiver operating characteristic (SROC) 0.99. Likelihood ratios and Fagan's nomogram suggested that the HCVcAg assay with DBS samples can confirm or rule out active HCV infection with over 92% accuracy in high‐prevalence settings (≥5%). However, in low‐prevalence settings (≤1%), a confirmatory test must be required for positive results. The ability of the test to identify people without HCV infection was high regardless of HCV prevalence, with an error rate of less than 3%. This meta‐analysis is subject to limitations, particularly due to the number of included studies and significant heterogeneity among them. HCV screening using the Abbott ARCHITECT HCV Ag assay with DBS samples showed excellent diagnostic performance, but its external validity may be limited when HCV prevalence is low (≤1%).

The multiple regression model statistical technique is employed to analyze the relationship between the dependent variable and several independent variables. The multicollinearity problem is one of the issues affecting the multiple regression model, occurring in regard to the relationship among independent variables. The ordinal least square is the standard method to evaluate parameters in the regression model, but the multicollinearity problem affects the unstable estimator. Liu regression is proposed to approximate the Liu estimators based on the Liu parameter, to overcome multicollinearity. In this paper, we propose a modified Liu parameter to estimate the biasing parameter in scaling options, comparing the ordinal least square estimator with two modified Liu parameters and six standard Liu parameters. The performance of the modified Liu parameter is considered, generating independent variables from the multivariate normal distribution in the Toeplitz correlation pattern as the multicollinearity data, where the dependent variable is obtained from the independent variable multiplied by a coefficient of regression and the error from the normal distribution. The mean absolute percentage error is computed as an evaluation criterion of the estimation. For application, a real Hepatitis C patients dataset was used, in order to investigate the benefit of the modified Liu parameter. Through simulation and real dataset analysis, the results indicate that the modified Liu parameter outperformed the other Liu parameters and the ordinal least square estimator. It can be recommended to the user for estimating parameters via the modified Liu parameter when the independent variable exhibits the multicollinearity problem. [ABSTRACT FROM AUTHOR]

Background: Diffuse large B-cell lymphoma (DLBCL) has heterogeneity in its behavior, and pathological and molecular identification. Hematopoiesis is regulated by microRNAs thus its aberrant expression predisposes to myeloid and lymphoid neoplasms the current research aimed to explore serum miR-26a-5p and miR-199b-5p in patients with DLBCL and to evaluate its correlation with clinicopathological features and treatment protocols of NHLs among Egyptian patients with Hepatitis C virus (HCV)Infection. Methods: We enrolled 60 participants; 30 patients with DLBCL and 30 healthy persons as the control group. all subjects were screened for the presence of HCV-RNA in both plasma and PBMCs. miR-26a-5p and miR-199b-5p levels were determined by RT-PCR. Results: Serum miR-26a-5p and miR-199b-5p level values were downregulated in DLBCL patients with HCV and OCI compared to non-HCV and controls. There were significantly higher values of both miR-26a-5p and miR-199b-5p levels in patients with complete response(n=15,50%) compared to partial response (n= 5,16.7%) and primary refractory (n=10,33.3%), p=0.001. Noteworthy, there were statistically significant negative correlations between miR-26a-5p, miR-199b-5p, LDH, and total bilirubin. Linear regression tests revealed that among examined associated variables, only LDH was the independent variable associated with miR-26a-5p and miR-199b-5p, P < 0.001. Conclusions:Serum miR-26a-5p and miR-199b-5p levels were down regulated in DLBCL patients, especially with HCV infection. Thus, these epigenetic markers could provide a new era of precision medicine to better refine diagnosis, prognostication, and rational treatment. [ABSTRACT FROM AUTHOR]

Hepatocellular carcinoma (HCC) is the most prevalent primary liver cancer, ranking as the sixth most common cancer worldwide and the fourth leading cause of cancer-related deaths. Most HCC cases originate from cirrhotic livers, typically due to chronic liver diseases, such as hepatitis B (HBV) and hepatitis C (HCV) infections, and alcoholism. HCC cells often harbor numerous somatic mutations that are implicated in HCC development, but epigenetic factors, such as miRNA interference, can also affect HCC initiation and progress. miRNA-221 has been explored as a factor affecting HCC development in HCC of viral etiology, but little is known about its effects on gene expression in alcohol-associated HCC. This study aimed to explore potentially similar gene expression aberrations underlying viral and alcohol-induced HCC. We analyzed available transcriptome data from non-tumor hepatocytes and viral-induced HCC tissues. The most notable differences in gene expression associated with miRNA-221 between non-tumor hepatocytes and viral-induced HCC involved NTF-3 and MYBL1 genes. To assess these data in alcohol-induced HCC, we examined 111 tissue samples: tumor tissue and cirrhotic tissue samples from 37 HCC patients and 37 samples from non-tumor liver tissue using RT-Q PCR. We found no significant difference in NTF-3 expression, but MYBL1 expression was significantly lower in HCC tissue compared to non-tumor hepatocytes and cirrhotic tissue. Our findings highlight the importance of the MYBL1 gene in HCC development and emphasize the need for diverse approaches in evaluating tumor mechanisms. [ABSTRACT FROM AUTHOR]

Background: Direct oral anticoagulants (DOACs) are recommended for the management of thrombosis prophylaxis, especially in patients with atrial fibrillation. As substrates of cytochrome P450 (CYP) 3A4 and/or P-glycoprotein, they are implicated in potential drug–drug interactions. NS5A/NS5B inhibitors are direct-acting agents (DAAs) against the Hepatitis C Virus (HCV) infection that exert a mild inhibition of P-glycoprotein without effects on CYP3A4. A DOAC and NS5A/NS5B inhibitor co-administration may lead to an increased risk of bleeding. Real-world data on the concomitant use of DOACs and DAAs are scarce. On this purpose, we perform a retrospective analysis on the risk of vascular adverse events (bleeding and thrombosis) among HCV patients under DOAC/DAA therapy, even in advanced liver disease. Methods: Between May 2015 and April 2023, patients treated with sofosbuvir-based DAA regimens and DOACs were consecutively included in this study from 12 Italian medical centers. Baseline characteristics, especially concerning bleeding risk and liver function, were collected. The occurrence of bleeding events, classified as major and minor, was the primary endpoint. Secondary endpoints were the rate of any thrombotic events and/or the need for discontinuation of one or both treatments. Moreover, a cohort of patients, matched by demographic characteristics (age and sex), that switched to vitamin K antagonists (VKAs) during the antiviral treatment was compared with the DOAC/DAA group. Results: A total of 104 patients were included. Thirty-eight of them (36.5%) were cirrhotic. Atrial fibrillation was an indication for anticoagulation in almost all cases (76%). Rivaroxaban (35.6%) was the most used DOAC, followed by apixaban (26.9%), dabigatran (19.2%) and edoxaban (18.3%). Sofosbuvir/velpatasvir (78.8%) was the most prescribed DAA, and all patients were already on anticoagulant therapy before the start of DAAs. During concomitant DOAC/DAA treatment, no major bleeding events were recorded, while four minor bleeding events occurred, but none resulted in DAA or DOAC discontinuation. At univariate analysis, the only additional risk factor statistically related to bleeding events was the anticoagulant therapy (hazard ratio [HR]: 13.2, 95% confidence interval 1,6-109). Performing an evaluation by a LOGIT binomial analysis with demographic characteristics, the antiplatelet therapy remained statistically associated to bleeding events. No significant differences were found in the rate of clinically relevant bleeding when the main population was compared with the VKA-switched cohort. A single major bleeding event leading to anticoagulation and DAA discontinuation was reported in VKA-switched matched cohort. Conclusions: In our study, the concomitant use of NS5A/NS5B inhibitors with DOAC showed good safety, and the only risk factor associated with bleeding events was the concomitant antiplatelet therapy. These findings support the use of DOACs during sofosbuvir-based HCV treatment, even in advanced liver disease. Replacing DOACs with VKAs does not appear to be of clinical benefit.

Background and Aims: Chronic hepatitis D infection is the most severe form of viral hepatitis and can rapidly progress to cirrhosis or hepatocellular carcinoma. Despite recommendations for systematic screening of hepatitis B surface antigen (HBsAg)‐positive individuals, data from real‐world studies have reported a low frequency of hepatitis D (or delta) virus (HDV) screening. Our cross‐sectional analysis evaluated the diagnostic cascade for hepatitis D infection in tertiary centres and described the characteristics of HDV‐positive patients. Methods: A total of 6772 individuals who tested HBsAg positive for the first time between 2018 and 2022 were retrospectively included. Demographic, clinical and laboratory data were analysed. Results: A total of 5748 HBsAg‐positive individuals (84.9%) were screened for HDV infection. The screening rate varied from 63% to 97% according to the screening strategy used in the centres including or not HDV reflex testing. The prevalence of HDV infection was 6.3%. HDV RNA levels were determined in 285 of the 364 (78.3%) HDV antibody screening‐positive patients, and 167 (58.6%) had active HDV infection. 66.8% were males, with a mean age of 44.9 years. A total of 97.5% were born abroad, and 92.9% were HBeAg negative. At the time of diagnosis, HDV RNA levels were 6.0 Log UI/mL; 60.1% had alanine aminotransferase >40 U/L, and 56.3% had significant fibrosis (≥F2), including 41.6% with cirrhosis. The most common genotype was HDV‐1 (75.4%). Coinfections were not uncommon: 7.4% were HIV positive, and 15.0% were HCV antibody positive. Conclusions: The present study highlights the need for increased screening and monitoring of HDV infection. Reflex testing helps to identify HDV‐infected individuals. [ABSTRACT FROM AUTHOR]

Introduction Immune checkpoint inhibitor (ICI) combinations extend overall survival (OS) while anti-PD-1/L1 monotherapy is non-inferior to sorafenib in treatment-naïve, patients with advanced hepatocellular carcinoma (HCC). Clinicogenomic features are posited to influence patient outcomes. Methods The primary objective of this retrospective study was to define the clinical, pathologic, and genomic factors associated with outcomes to ICI therapy in patients with HCC. Patients with histologically confirmed advanced HCC treated with ICI at Memorial Sloan Kettering Cancer Center from 2012 to 2022 were included. Association between clinical, pathological, and genomic characteristics were assessed with univariable and multivariable Cox regression model for progression-free survival (PFS) and OS. Results Two-hundred and forty-two patients were treated with ICI-based therapy. Patients were predominantly male (82%) with virally mediated HCC (53%) and Child Pugh A score (70%). Median follow-up was 28 months (0.5-78.4). Median PFS for those treated in 1st line, 2nd line and ≥ 3rd line was 4.9 (range: 2.9-6.2), 3.1 (2.3-4.0), and 2.5 (2.1-4.0) months, respectively. Median OS for those treated in 1st line, 2nd line, and ≥ 3rd line was 16 (11-22), 7.5 (6.4-11), and 6.4 (4.6-26) months, respectively. Poor liver function and performance status associated with worse PFS and OS, while viral hepatitis C was associated with favorable outcome. Genetic alterations were not associated with outcomes. Conclusion Clinicopathologic factors were the major determinates of outcomes for patients with advanced HCC treated with ICI. Molecular profiling did not aid in stratification of ICI outcomes. Future studies should explore alternative biomarkers such as the level of immune activation or the pretreatment composition of the immune tumor microenvironment. [ABSTRACT FROM AUTHOR]

Background The current hepatitis B (HBV) and hepatitis C virus (HCV) screening practices may fail to detect many infected patients who could benefit from new therapeutic agents to limit progression to cirrhosis and hepatocellular carcinoma. Objectives This study assessed the test positivity rate and cascade of care of viral hepatitis patients in primary care in a low endemic region as well as the testing policy of abnormal alanine aminotransferase (ALT) level. Methods This is a retrospective clinical audit among primary health care practices in Flanders, Belgium, assessing patients with an active medical file between 2019 and 2021. Results A total of 84/89 (94.4%) primary health care practices participated representing 621,573 patients of which 1069 patients (0.17%) were registered as having viral hepatitis, not further specified. Detailed information was available from 38 practices representing 243,723/621,573 (39.2%) patients of which 169 (0.07%) were HBsAg positive and 99 (0.04%) anti-HCV positive. A total of 96/134(71.6%) chronic HBV-infected and 31/77(40.3%) chronic HCV-infected patients were referred to a hepatologist. A total of 30,573/621,573(4.9%) patients had an abnormal ALT level, and by at random selection, more detailed information was obtained on 211 patients. Information on high-risk groups was missing in up to 60%. In patients with abnormal ALT level, HBsAg and anti-HCV testing were conducted in 37/211(17.5%) and 25/211(11.8%), respectively. Conclusion In a low endemic region, the testing rate and cascade of care of HBV and HCV-infected patients can be improved in primary care, especially in high-risk groups and patients with abnormal ALT levels.

Objectives: HIV/hepatitis C virus (HCV) co‐infection among people who inject drugs (PWID) remains a global health problem. The goal of our study was to evaluate, in a real‐world setting, success rates of sustained virological response (SVR) using direct‐acting antivirals (DAAs) to treat a population of PWID living with HCV/HIV. Methods: This was a prospective single‐center observational study. We collected demographic, socioeconomic, and clinical data pertaining to HIV and HCV infection in PWID with several barriers to care. We identified risk factors for SVR failure. Results: Among 130 individuals retained to HIV care, we planned HCV treatment in 119/130 (91.5%); 106/119 (89.1%) started treatment with DAAs and 100/106 (94.3%) completed treatment. People not starting treatment were more often in active opioid drug use (odds ratio [OR] 0.25; 95% confidence interval [CI] 0.07–0.97, p = 0.045) and benzodiazepine abuse (OR 0.25; 95% CI 0.07–0.95, p = 0.042). Only 86/100 (86%) were tested for SVR at 12 weeks (SVR12) and 72/86 (83.7%) achieved SVR. PWID in opioid substitution programmes tended to return for SVR12 testing more often (54.7% vs. 30%, p = 0.081). Individuals in active opioid drug use (OR 0.226; 95% CI 0.064–0.793, p = 0.02) or with poor adherence (OR 0.187; 95% CI 0.043–0.814, p = 0.025) were less likely to achieve SVR. At the end of our study period, 113/119 (95%) treatment‐eligible patients remained alive. HCV infection was cured in 68/113 (61.1%) people. Conclusions: Our findings underscore the importance of prioritizing combatting substance use to achieve HCV elimination goals. A systematic approach with effort to overcome barriers to receiving and completing treatment and encourage to enrol in opioid substitution programmes if not possible to completely abstain from use, can help increase chances of HCV cure.

This study was conducted as a single‐site, open‐label, randomized, replicated crossover trial with 4 treatment periods. The aim was to evaluate the bioequivalence of a generic test drug containing velpatasvir and sofosbuvir compared to an established brand‐name medication in healthy White subjects under fasting conditions. Blood samples were collected at specified intervals up to 72 hours after dosing to measure the concentrations of velpatasvir and sofosbuvir using a certified high‐performance liquid chromatography with tandem mass spectrometry method. The bioequivalence of the 2 formulations was confirmed when statistical analysis showed that confidence intervals for the log‐transformed peak concentration and area under the concentration‐time curve from time 0 to the last quantifiable sample were within an acceptable range from 80% to 125%. Criteria for bioequivalence were met for both area under the concentration‐time curve from time 0 until the last quantifiable sample and peak concentration parameters. No adverse effects were reported during this trial in both groups. [ABSTRACT FROM AUTHOR]

Background: The aim of this study was to determine the psychometric properties of the Spanish-language version of the HIV-Symptom Index (HIV-SI) questionnaire in Spanish patients undergoing antiretroviral therapy. Methods: Between 2014 and 2016, an observational, multicenter, prospective cohort study was conducted in seventeen Spanish hospitals to validate HIV-SI questionnaire in terms of: construct validity (confirmatory factor analysis), internal consistency (Cronbach's alpha), convergent validity (Pearson's correlation coefficient) and Known-group validity. In addition, a sensitivity to change analysis was also performed. Results: A total of 232 patients were included in the study. They had a mean age of 46.17 (SD9.82) and were 75% male. The median overall score for the HIV-SI was 10 (IQR 4– 19.5) and the most common symptoms reported were feelings of nervousness or anxiety, fatigue or energy loss, feeling sad or depressed, stomach pain or bloating, and difficulty sleeping. In the current study, the Spanish HIV-SI questionnaire showed a high internal consistency (α = 0.89) and adequate construct validity (CFI and TLI > 0.90). When contrasted with the MOS-HIV questionnaire, an inverse correlation was found. It showed a good association with the mental (r=-0.61; P < 0.0001) and physical score (r=-0.60; P < 0.0001). In a multivariate analysis, the age of the patient, female condition, hepatitis C coinfection, concomitant treatment and non-adherence resulted in a higher HIV-SI score. Conclusions: Our study has shown that the Spanish HIV-SI is a valid and reliable self-administered PROM for routine measurement of patient- reported symptoms among Spanish patients on antiretroviral treatment.

Purpose: Analyze maternal and infant characteristics by Neonatal Opioid Withdrawal Syndrome (NOWS) status and examine the association between mothers with Hepatitis C Virus (HCV) and infants diagnosed with NOWS. Methods: Hospital discharge diagnoses of low-income women in Tennessee were used to identify NOWS cases (n = 1,369) in 2013 and 2014 and randomly selected controls (n = 1,369) were matched on county of residence and birth year. Maternal and infant characteristics were obtained by linking these data to birth certificate data. Results: Of Tennessee's 683 cases of NOWS in 2013 and 686 in 2014, most (69%) occurred in Eastern Tennessee. Mothers of infants with NOWS were more likely to be older, unmarried, and white than mothers of infants without NOWS. Mothers of infants with NOWS also faced greater health risk: more smoking, HCV, herpes simplex diagnosis, and no or less frequent prenatal care (p <.0001). Infants with NOWS were more likely to present with infection, be admitted into the NICU, have lower birth weight, be enrolled in TennCare, but less likely to be breastfed than infants without NOWS (p <.0001). After adjusting for demographic factors and smoking, compared to mothers of infants without NOWS, mothers of infants with NOWS had an alarmingly increased odds of HCV [OR = 12.97 (95% CI 7.42, 22.66)]. Conclusions: This study emphasizes the complexity of challenges facing families impacted by NOWS, the importance of multifaceted prevention, and the need to conduct HCV testing in NOWS infants.

In 2021, the Israel Ministry of Health began a national hepatitis C elimination program. Implementing a World Health Organization goal, Israel’s program involved targeted screening, barrier minimization, workup simplification, awareness campaigns, and a patient registry. We evaluated program costs for testing and treatment. By May 15, 2023, the program had identified 865,382 at-risk persons, of whom 555,083 (64.3%) were serologically screened for hepatitis C virus (HCV), which was detected in 24,361 (4.4%). Among 20,928 serologically positive patients, viremia was detected in 13,379 (63.9%), of whom 10,711 (80%) were treated, and 4,618 (96.5%) of 4,786 persons receiving posttreatment HCV RNA testing had sustained virologic response. We estimated costs of ₪14,426 (new Israel shekel; ≈$3,606 USD) per person whose HCV infection was diagnosed and successfully treated. The program yielded screening and treatment in almost two thirds of the identified at-risk population. Although not eliminated, HCV prevalence will likely decrease substantially by the 2030 target.

Background: Treating hepatitis C virus (HCV) in people who inject drugs (PWID) has been associated with increased health-related quality of life (HRQOL). Polysubstance use (PSU) is common among PWID, but no studies have investigated PSU influence on PWID's HRQOL HCV treatment. Methods: Participants included 150 PWID receiving HCV treatment at opioid agonist treatment clinics in Bronx, NY. The EQ-5D-3 L measurement tool assessed five health dimensions producing an index of HRQOL measured at baseline, 4-, 8-, and 12-weeks during treatment and 12- and 24-weeks post-treatment. PSU was determined at baseline. Generalized estimating equations assessed the influence of baseline PSU on changes in mean EQ-5D-3 L index over time. Results: Of the 150 participants, 46 (30.7%) reported PSU and mean HRQOL overall was 0.655, indicating moderate HRQOL. Mean HRQOL was lower at all time-points for the PSU group compared to the non-PSU group. Though PSU group showed improvements in mean HRQOL from baseline (0.614) to 4-, 12- and follow-up week 24 (0.765, 0.768, and 0.731, respectively), the mean change of HRQOL scores was not significantly associated with PSU (p-value =.956). Conclusions: For individuals with PWID, our study showed no difference in HRQOL between those who did and did not engage in PSU following HCV treatment. [ABSTRACT FROM AUTHOR]

Background: Rapid skeletal muscle loss adversely affects the clinical outcomes of liver cirrhosis. However, the relationships between the annual changes in skeletal muscle area (ΔSMA/year) and the etiology of cirrhosis, factors associated with muscle loss, and risk of mortality remains unclear. Methods: A total of 384 patients who underwent multiple computed tomography (CT) scans between March 2004 and June 2021 were enrolled in this study (median age, 67 years; 64% men; median model for end-stage liver disease score, 9). Body composition and ΔSMA/year were estimated using a 3D image analysis system and data from at least two distinct CT scans. Differences in ΔSMA/year among different etiologies of cirrhosis, factors associated with rapid muscle loss (defined as ΔSMA/year ≤ − 3.1%), and the association between ΔSMA/year and mortality were examined. Results: Patients with alcohol-associated liver disease (ALD) cirrhosis experienced more rapid muscle loss (ΔSMA/year, − 5.7%) than those with hepatitis B (ΔSMA/year, − 2.8%) and hepatitis C cirrhosis (ΔSMA/year, − 3.1%). ALD cirrhosis was independently associated with ΔSMA/year ≤ − 3.1% after adjusting for age, sex, and liver functional reserve. Over a median follow-up period of 3.8 years, ALD cirrhosis, ΔSMA/year ≤ − 3.1%, and low subcutaneous adipose tissue level were found to be significantly associated with reduced survival. ALD cirrhosis (hazard ratio [HR], 2.43; 95% confidence interval [CI] 1.12–5.28) and ΔSMA/year ≤ − 3.1% (HR, 3.68; 95% CI 2.46–5.52) were also predictive of mortality. Conclusions: These results suggest that ALD cirrhosis increases the risk of rapid muscle loss and mortality in affected patients. [ABSTRACT FROM AUTHOR]

Disengagement from care among people with HIV (PWH) and hepatitis C (HCV) increases the risks of adverse health outcomes and poses significant barriers to achieving global HIV and HCV elimination goals. In accordance with the Joanna Briggs Institute framework, a scoping review was conducted to synthesize and highlight existing gaps in the literature on (dis)engagement in care among PWH and HCV. We searched for original studies on (dis)engagement in care among PWH and HCV in high-income countries using eight electronic databases from inception to May 2023. Our search yielded 4462 non-duplicated records, which were scoped to 27 studies. Definitions of (dis)engagement in care were diverse, with considerable heterogeneity in how retention was operationalized and temporally measured. Studies identified predictors of (dis)engagement to be related to drug and substance use (n = 5 articles), clinical factors (n = 5), social and welfare (n = 4), and demographic characteristics (n = 2). When engagement in care was treated as an exposure, it was associated with HCV treatment initiation (n = 3), achieving sustained virological response (n = 2), and maintaining HIV viral suppression (n = 1). Interventions to improve care engagement among PWH and HCV were limited to five studies using cash incentives (n = 1) and individual case management (n = 4). (Dis)engagement in care is a dynamic process influenced by shifting priorities that may 'tip the balance' towards or away from regularly interacting with healthcare professionals. However, inconsistent definitions render cross-study comparisons and meta-analyses virtually impossible. Further research needs to establish a standardized definition to identify patients at high risk of disengagement and develop interventions that leverage the nested HIV/HCV care cascades to retain and recover patients lost from care.

Background: Hepatitis C virus (HCV) antibody self-testing (HCVST) may help expand screening access and support HCV elimination efforts. Despite potential benefits, HCVST is not currently implemented in Pakistan. This study aimed to assess the usability and acceptability of HCVST in a high HCV prevalence informal settlement in Karachi, Pakistan. Methods: We performed a cross-sectional study in a hepatitis C clinic from April through June 2023. Participants were invited to perform a saliva-based HCVST (OraSure Technologies, USA) while following pictorial instructions. A study member evaluated test performance using a standardized checklist and provided verbal support if a step could not be completed. Perceived usability and acceptability were assessed using a semi-structured questionnaire. The HCVST was considered successful if the participant was able to complete all steps and correctly interpret test results. Overall concordance and positive and negative agreement were estimated in comparison with the HCVST result read by the study member (inter-reader concordance and agreement) and result of a second rapid HCV test (Abbott Diagnostics Korea Inc, South Korea) performed by a trained user (inter-operator concordance and agreement). Results: The study included 295 participants of which 97 (32%) were illiterate. In total, 280 (95%, 95% CI 92–97%) HCVSTs were successful. Overall, 38 (13%) people performed the HCVST without verbal assistance, 67 (23%) needed verbal assistance in one step, 190 (64%) in two or more. Assistance was most often needed in managing the test buffer and test reading times. The inter-reader concordance was 96% and inter-operator concordance 93%. Inter-reader and inter-operator positive percent agreement were 84 and 70%, respectively. All participants reported they would use HCVST again and would recommend it to friends and family. Conclusion: Saliva-based HCVST was very well accepted in this clinic-based setting. However, many people requested verbal support in several steps, highlighting the need for clear instructions for use and test devices that are simple to use, particularly in low literacy settings. Moderately low positive percent agreement with the results of a rapid test performed by a trained user highlights potential uncertainty in the accuracy of HCVST in the hands of lay users.

Background: Hepatitis C virus (HCV) infection can lead to a type of primary liver cancer called hepatocellular carcinoma (HCC). Georgia, a high HCV prevalence country, started an HCV elimination program in 2015. In addition to tracking incidence and mortality, surveillance for the HCV-attributable fraction of HCC is an important indicator of the program's impact. This study assesses HCV infection-attributable HCC in the Georgian population. Methods: This case–control study utilized HCV programmatic and Georgian Cancer Registry data from 2015–2019. Bivariate logistic regression and age- and sex-stratified analyses assessed HCV and liver cancer association. HCV-attributable liver cancer proportions for the HCV-exposed and total population were calculated. A sub-analysis was performed for HCC cases specifically. Results: The total study population was 3874 with 496 liver cancer cases and 3378 controls. The odds for HCV-infected individuals developing liver cancer was 20.1 (95% confidence interval [CI] 15.97–25.37), and the odds of developing HCC was 16.84 (95% CI 12.01–23.83) compared to the HCV-negative group. Odds ratios varied across strata, with HCV-infected older individuals and women having higher odds of developing both liver cancer and HCC. A large proportion of liver cancer and HCC can be attributed to HCV in HCV-infected individuals; however, in the general population, the burden of liver cancer and HCC cannot be explained by HCV alone. Conclusion: HCV was significantly associated with a higher risk of developing liver cancer and HCC in the Georgian population. In addition, given Georgia's high HCV burden, increased HCC monitoring in HCV-infected patients is needed. [ABSTRACT FROM AUTHOR]

Background: Transgender women (hereafter "trans women") face social marginalization, stigma, and discrimination and experience a high burden of HIV. More recently, trans women have been identified as having a high risk for hepatitis C (HCV) infection. The interaction between these two diseases and the risks for HIV/HCV co-infection among trans women are understudied. Objective: To characterize epidemiological, behavioral, and socio-structural interactions between HIV and HCV infections among trans women. Methods: This cross-sectional study examined data from a community-based survey of trans women in San Francisco recruited through respondent-driven sampling (RDS) in 2019/2020. Face-to-face interviews collected data on demographics, medical history, drug injection practices, sexual behavior, and socio-structural factors (e.g., poverty, housing insecurity, incarceration, social support). HIV and HCV antibodies were detected using oral fluid rapid tests and prior diagnosis and treatment were collected by self-report. Blood specimens were collected to confirm antibodies using ELISA. Multinomial logistic regression analysis characterized factors associated with HIV infection alone, HCV infection alone, and HIV/HCV co-infection compared to neither infection. Results: Among 201 trans women recruited, HIV prevalence was 42.3%; HCV infection by history or current seroprevalence was 28.9%; evidence for both HIV and HCV infection was present for 18.9%. Two-thirds of trans women (67.2%) had been incarcerated; 30.8% had ever injected drugs. History of injection drug use and receiving emotional support from family were factors found in common for HIV infection, HCV infection, and HIV/HCV co-infection compared to no infection. Having a sexual partner who injects drugs was associated with HIV infection alone. Not lacking care due to cost and older age were associated with co-infection. Older age was also associated with HCV infection. Of trans women with HIV infection, 91.8% had accessed HIV care, whereas only 62% with HCV had accessed some form of care. Conclusions: Our study found high levels of HIV, HCV, and HIV/HCV co-infection among trans women in San Francisco. We found common associations between HIV and HCV through injection practices and emotional support, but having a sexual partner who injects drugs was not associated with HCV infection alone or co-infection. We note a substantial gap in the treatment of HCV for trans women, including those in HIV care, that needs to be urgently addressed. [ABSTRACT FROM AUTHOR]
