Endemic maintenance of human-related hepatitis E virus strains in synurbic wild boars, Barcelona Metropolitan Area, Spain

Hepatitis E virus (HEV), shared by humans, domestic animals, and wildlife, is an emerging global public health threat. Because wild boars are a major reservoir of HEV, the new zoonotic interfaces resulting from wild boar population increase and synurbization significantly contribute to increasing the risk of zoonotic transmission of HEV.This study characterizes HEV strains of synurbic wild boars and assesses their relationship with sympatric human and domestic swine HEV strains. We analyzed the faeces of 312 synurbic wild boars collected from 2016 to 2021 in the Barcelona Metropolitan Area (BMA), where there is a high density of wild boars, and found 7 HEV-positive samples among those collected between 2019 and 2020. The molecular analysis of these isolates, along with 6 additional wild boar HEV isolates from a previous study, allowed us to establish a close phylogenetic relationship between these HEV strains and human HEV isolates from sympatric blood donors and domestic pigs from Catalonia. HEV-positive wild boar samples belonged to piglet, juvenile and yearling individuals, but not adults, indicating the endemic maintenance of HEV in the wild boar population of the BMA by naïve young individuals. All wild boar HEV isolates in this study classified within HEV genotype 3.The results show, for the first time, a close molecular similarity between the HEV strains endemically maintained by the synurbic wild boars in the BMA and citizens from the same area and period. The data could also indicate that HEV infection presents a seasonal and interannual variability in wild boars of BMA. Further investigation is required to unveil the HEV transmission routes between synurbic wild boars and sympatric citizens. These findings can serve in other synurbic wildlife-human interfaces throughout the world.

Characteristics and prognosis of hepatocellular carcinoma patients after direct-acting antiviral hepatitis C virus therapy in a single medical center in Egypt

Objective: Hepatocellular carcinoma (HCC) incidence has increased dramatically over the previous two decades and is anticipated to rise further in some countries, notably the United States, by 2030. HCC is most widespread in Asia and Africa, where hepatitis B and C are ubiquitous and lead to the development of chronic liver disease and, finally, HCC. In this study, we examined changes in the characteristics and prognosis of HCC patients, as well as the risk of developing HCC after direct-acting antiviral (DAA) medication.Methods: The study enrolled all individuals who attended the Clinical Oncology and Nuclear Medicine Department, Suez Canal University Hospital, Ismailia, Egypt, with a proven diagnosis of HCC in the period between January 2020 and December 2021. HCC is diagnosed based on radiographic appearance (arterial enhancement phase and delayed washout phase) or compatible histology.Results: This retrospective cohort included 254 HCC patients, separated into three groups. Kaplan-Meier curves with log-rank analysis revealed that hepatitis C virus (HCV) treatment therapy considerably reduced the time to HCC development following hepatitis diagnosis (p < .001). HCV therapy had a substantial impact on progression-free survival and overall survival in HCC patients (p < .001).Conclusions: The emergence of DAA medication has greatly altered the management of HCV patients in the context of HCC. DAAs have been shown to be both safe and beneficial in these individuals, particularly in terms of lowering the risk of hepatic decompensation. DAAs have been reported to enhance overall survival in patients with cirrhotic HCV-related HCC, most likely due to decreased hepatic decompensation.

Real-world trends in acute viral hepatitis in Japan: A nationwide questionnaire-based survey.

The actual incidence of acute viral hepatitis in Japan remains unclear. We aimed to investigate trends in the incidence of acute hepatitisB and C infections in Japan. A nationwide, multicenter, retrospective questionnaire-based survey was conducted. Participating hospitals received questionnaires through nationwide geographically distributed regional core centers certified as specialists in hepatitis treatment. The questionnaire included hospital size and the number of patients diagnosed with acute hepatitisB or C during each fiscal year (FY) from 2015 to 2022. The sex distribution in each FY was also documented. Comparisons were made before and during the COVID-19 era (2015-2019 vs. 2020-2022), and between populous and non-populous prefectures. Responses to the questionnaires were obtained from 127 institutions in 29 prefectures covering eight regions in Japan. A median of 127.0 patients with acute hepatitisB (interquartile range [IQR] 106.5-131.8 patients) were reported during each FY, and the incidence significantly decreased during the fiscal years 2020-2022 compared with the fiscal years 2015-2020 (median 96.0 [IQR 91.0-103.0] patients vs. 131.0 [IQR 128.0-134.0] patients; p=0.03). A median of 10.0 (IQR, 7.8-13.5) patients were reported with acute hepatitisC during each FY. The proportions of men in acute hepatitis B and C were significantly higher in populous prefectures. Populous prefectures had a higher proportion of men among viral hepatitis patients than non-populous prefectures. Estimating the high-risk populations in each area could provide insights to advance the elimination of viral hepatitis.

Effects of four-week lasting aerobic treadmill training on hepatic injury biomarkers, oxidative stress parameters, metabolic enzymes activities and histological characteristics in liver tissue of hyperhomocysteinemic rats.

Disruptions in homocysteine (Hcy) metabolism may increase the liver's susceptibility to developing conditions such as alcoholic liver disease, viral hepatitis, hepatocellular carcinoma (HCC), and cirrhosis. The aim of this study was to examine effects of aerobic treadmill training on hepatic injury biomarkers in sera, oxidative stress parameters, the activity of metabolic enzymes, and histological characteristics in the liver tissue of rats with experimentally induced hyperhomocysteinemia. Male Wistar albino rats were divided into four groups (N = 10, per group): C-saline 0.2mL/day sc. 2×/day for 14days + saline 0.5mL ip.1×/day for 28days; H-homocysteine 0.45µmol/g b.w. 2×/day for 14days + saline 0.5mL ip.1×/day for 28days; CPA-saline 0.2mL/day sc. 2×/day for 14days + aerobic treadmill training for 28days; and HPA-homocysteine 0.45µmol/gb.w. 2×/day for 14days + aerobic treadmill training for 28days. The serum albumin concentration was decreased in both physically active (PA) groups compared to sedentary groups. Concentration of malondialdehyde in liver tissue homogenates was lower in both PA groups compared to the H group. The total lactate dehydrogenase and malate dehydrogenase activities were significantly elevated in the HPA group compared to the C and H groups. Activities of aminotransferases in sera samples, and activities of catalase and superoxide dismutase in liver tissue did not significantly differ between groups. No significant histological changes were found in liver tissue in groups. This study demonstrated that aerobic treadmill training can reduce lipid peroxidation in liver tissue under hyperhomocysteinemic conditions, providing a protective effect. However, hyperhomocysteinemia can alter energy metabolism during aerobic exercise, shifting it toward anaerobic pathways and leading to elevated lactate dehydrogenase activity in the liver. Given that conditions like hyperhomocysteinemia are associated with an increased risk of cardiovascular diseases and liver damage, understanding how exercise influences these dynamics could guide therapeutic approaches.

A Programme of Hepatitis C Surveillance With Active Linkage to Care (HEAL) for Inpatients in Two Tertiary Hospitals in Jiangsu, China.

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.

First detection of Hepatitis E virus (Rocahepevirus ratti) in French urban wastewater: Potential implications for human contamination

Hepatitis E virus (HEV) is considered as an emerging zoonotic pathogen circulating in a wide range of animals. In recent decades, the genus Paslahepevirus frequently isolated in pigs were the most involved in human clinical practice. In addition, the genus Rocahepevirus have been isolated in rodents, and transmission to humans is increasingly reported worldwide, although gaps remain regarding the exposure factors. In this study, the presence of HEV was investigated in urban wastewater, swine slaughterhouse wastewater and river waters, in a geographical area where its circulation had previously been reported. In addition to the expected detection of Paslahepevirus in almost all waters samples collected, Rocahepevirus strains were detected with the same frequencies in urban and river waters, at concentrations up to 40-fold higher. No Rocahepeviruses were detected in swine slaughterhouse wastewater. This is the first study demonstrating the presence of Rocahepevirus in French wastewater. Although no evidence of transmission was reported among patients followed for a suspected HEV infection in the same area between April 2019 and October 2023 (i.e. 135/3078 serological tests positive for anti-HEV IgM detection; 46/822 blood samples positive for Paslahepevirus genome detection but none for Rocahepevirus), the circulation of Rocahepevirus in waters in such concentrations raises the question of the possible zoonotic transmission to human. Indeed, the waterborne transmission of HEV is now well documented in industrialized countries, and the exploration of the growing number of human infections in Europe involving Rocahepevirus has not until now made it possible to clarify the transmission routes.

Inhibitory peptides derived from Hepatitis C virus NS5A for reducing clinical symptoms of dengue virus infection

Lethal Dengue Hemorrhagic Fever (DHF) and Dengue Shock Syndrome (DSS) caused by Dengue virus (DENV) infection necessitate the development of effective treatments. Peptides derived from the N-terminal amphipathic α-helix of hepatitis C virus (HCV) NS5A exhibit antiviral activity by disrupting liposomes with high curvatures, such as virus envelopes. This study engineered five peptides from HCV genotype 3a NS5A N-terminal α-helix and screened them for neutralizing efficacy against three DENV serotypes. Two peptides, 3a 3/20 and DS-05, showed superior therapeutic efficacy against DENV and were further evaluated in treating DHF/DSS induced by mouse-adapted DENV infection. Administration of 3a 3/20 and DS-05 post-infection significantly improved mortality and weight loss associated with DHF/DSS in AG6 mice. These peptides reduced viral load in internal organs and viremia to levels comparable with the positive control drug, JNJ-A07, a DENV NS3-NS4B inhibitor. Additionally, they attenuated the cytokine storm in the blood and expression of inflammatory cytokines in internal organ tissues, ameliorating liver and kidney dysfunction after DENV infection. Histopathological analysis revealed significant suppression of damages in internal organs. These findings suggest that the 3a 3/20 and DS-05 peptides improve clinical symptoms of DHF/DSS induced by DENV infection, indicating their potential for clinical application.

Neutrophil plasticity in liver diseases.

The liver has critical digestive, metabolic, and immunosurveillance roles, which get disrupted during liver diseases such as viral hepatitis, fatty liver disease, and hepatocellular carcinoma. While previous research on the pathological development of these diseases has focused on liver-resident immune populations, such as Kupffer cells, infiltrating immune cells responding to pathogens and disease also play crucial roles. Neutrophils are one such key population contributing to hepatic inflammation and disease progression. Belonging to the initial waves of immune response to threats, neutrophils suppress bacterial and viral spread during acute infections, and have homeostasis-restoring functions. Whereas during chronic insults, they display their plastic nature by responding to the inflammatory environment and develop new phenotypes alongside longer lifespans. This review summarizes the diversity in neutrophil function and subpopulations present at steady state, during liver disease, and during liver cancer.

Associated Factors of Viral Hepatitis Transmission among Hemodialysis Adult Patients

Background: Individuals suffering from chronic kidney disease (CKD) are more likely to die, particularly those with end-stage kidney disease. Surprisingly, these deaths are related to many diseases, and this mortality rate motivates us to identify additional risk factors that can be modified to improve survival in patients requiring hemodialysis. Hepatitis virus infection has been associated with many comorbidities other than the liver, such as kidney disease, cardiovascular disease, insulin resistance, diabetes mellitus, and lymphoproliferative disease. Objective: To estimate the hepatitis prevalence in hemodialysis units and assess the risk factors contributing to viral hepatitis infection in hemodialysis centers. Materials and Methods: Cohort study design conducted in dialysis centers-Najaf AL Ashraf\ Iraq , , May 2023. The sample was collected by questionnaire and by referring to patient records to measure the prevalence of viral hepatitis. Results: 72 patients with hepatitis in hemodialysis centers responded to study. Their ages ranged from 20-78 years. The group of participants (41-60 years old) constituted approximately half of sample, and the percentage of sex was males more than females. The prevalence of viral hepatitis was 10.3 %. Among patients with hemodialysis treatment, hepatitis B virus is less than C.

Hidden evolutionary constraints dictate the retention of coronavirus accessory genes.

Coronaviruses exhibit many mechanisms of genetic innovation, including the acquisition of accessory genes that originate by capture of cellular genes or through duplication of existing viral genes. Accessory genes influence viral host range and cellular tropism, but little is known about how selection acts on these variable regions of virus genomes. We used experimental evolution of mouse hepatitis virus (MHV) encoding a cellular AKAP7 phosphodiesterase and an inactive native phosphodiesterase, NS2 to model the evolutionary fate of accessory genes. After courses of serial infection, the gene encoding inactive NS2, ORF2, unexpectedly remained intact, suggesting it is under cryptic constraint uncoupled from the function of NS2. In contrast, AKAP7 was retained under strong selection but rapidly lost under relaxed selection. Experimental evolution also led to altered viral replication in a cell type-specific manner and changed the relative proportions of subgenomic viral RNA in plaque-purified viral isolates, revealing additional mechanisms of adaptation. Guided by the retention of ORF2 and similar patterns in related betacoronaviruses, we analyzed ORF8 of SARS-CoV-2, which arose via gene duplication and contains premature stop codons in several globally successful lineages. As with MHV ORF2, the coding-defective SARS-CoV-2 ORF8 gene remains largely intact, mirroring patterns observed during MHV experimental evolution, challenging assumptions on the dynamics of gene loss in virus genomes and extending these findings to viruses currently adapting to humans.

Phosphorylation of Ser711 residue in the hypervariable region of zoonotic genotype 3 hepatitis E virus is important for virus replication.

Hepatitis E virus (HEV) is distinct from other hepatotropic viruses because it is zoonotic. HEV-1 and HEV-2 exclusively infect humans, whereas HEV-3 and HEV-4 are zoonotic. However, the viral and/or host factors responsible for cross-species HEV transmission remain elusive. The hypervariable region (HVR) in HEV is extremely heterogenetic and is implicated in HEV adaptation. Here, we investigated the potential role of Serine phosphorylation in the HVR in HEV replication. We first analyzed HVR sequences across different HEV genotypes and identified a unique region at the N-terminus of the HVR, which is variable in the human-exclusive HEV genotypes but relatively conserved in zoonotic HEV genotypes. Using predictive tools, we identified four potential phosphorylation sites that are highly conserved in zoonotic HEV-3 and HEV-4 genomes but absent in human-exclusive HEV-1 strains. To explore the functional significance of these putative phosphorylation sites, we introduced mutations into the HEV-3 infectious clone and indicator replicon, replacing each Serine residue individually with alanine or aspartic acid, and assessed the impact of these substitutions on HEV-3 replication. We found that the phospho-blatant S711A mutant significantly reduced virus replication, whereas the phospho-mimetic S711D mutant modestly reduced virus replication. Conversely, mutations in the other three Serine residues did not significantly affect HEV-3 replication. Furthermore, we demonstrated that Ser711 phosphorylation did not alter host cell tropism of zoonotic HEV-3. In conclusion, our results showed that potential phosphorylation of the Ser711 residue significantly affects HEV-3 replication in vitro, providing new insights into the potential mechanisms of zoonotic HEV transmission.IMPORTANCEHEV is an important zoonotic pathogen, causing both acute and chronic hepatitis E and extrahepatic manifestation of diseases, such as neurological sequelae. The zoonotic HEV-3 is linked to chronic infection and neurological diseases. The specific viral and/or host factors facilitating cross-species HEV infection are unknown. The intrinsically disordered HVR in ORF1 is crucial for viral fitness and adaptation, both in vitro and in vivo. We hypothesized that phosphorylation of Serine residues in the HVR of zoonotic HEV by unknown host cellular kinases is associated with cross-species HEV transmission. In this study, we identified a conserved region within the HVR of zoonotic HEV strains but absent in the human-exclusive HEV-1 and HEV-2. We elucidated the important role of phosphorylation at the Ser711 residue in zoonotic HEV-3 replication, without altering the host cell tropism. These findings contribute to our understanding the mechanisms of cross-species HEV transmission.

Prevalence of hepatitis C virus hypervariable region 1 insertions and their role in antibody evasion.

Chronic hepatitis C virus (HCV) infection afflicts around 50 million people globally, causing ~250,000 deaths yearly. An effective vaccine needs to overcome high viral diversity and HCV's ability to evade neutralizing antibodies (NAbs). Rapid antigenic drift in the N-terminal motif of envelope protein E2, named hypervariable region 1 (HVR1), is critically involved in NAb evasion via an incompletely understood mechanism involving viral entry factors. The canonical length of HVR1 is 27 amino acids, but insertions of 2-4 amino acids was described in patients infected with genotype 1b. We aimed at determining whether HVR1 insertions may be underreported due to extreme HVR1 variability. We observed a 0.7% HVR1 insertion prevalence in routine NGS patient contigs. Thus, we performed direct sequence analysis of E1E2 sequences from 131 HCV infected patients. Interestingly, we observed that 3% of patients harbored viruses (genotype 1a, 2b, 3a) with dominant HVR1 insertions. Insertion of longer non-canonical HVR1s into HCV cell culture recombinants frequently caused loss of fitness. However, culture-viable viruses with HVR1 insertions were fully viable in vivo. Interestingly, in adapted genotype 1b recombinants with HVR1 insertions, we found internal HVR1 deletions, that increased antibody sensitivity, which surprisingly correlated more with reduced LDLr than reduced SR-BI dependency, indicating a role of LDLr in NAb evasion. Conversely, HVR1 insertions had no effect on receptor dependency, however, they modulated epitope-specific NAb sensitivity. HVR1 insertion prevalence and NAb sensitivity modulation indicate they represent a mechanism by which HCV evades emerging NAbs during infection.

Prognosis of Acute HEV Infection in Patients With Liver Cirrhosis: A Retrospective Study of 628 Chinese Patients.

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 of awareness and prevention of hepatitis B among Congolese healthcare workers: urgent need for policy implementation.

The Democratic Republic of Congo (DRC) is a country with many public health challenges, including those related to the prevention and management of viral hepatitis B. Healthcare workers, who are at the frontline of patient care, are particularly at risk of contracting and spreading this virus, especially given its high prevalence in the general population. This paper examines the level of awareness and preventive measures among Congolese healthcare workers. Overall, the data show that health workers are under-immunized and lack formal training in hepatitis B prevention and management. In addition to limited awareness, health facilities are insufficiently involved in the implementation of standardized infection control protocols, the provision of personal protective equipment and routine hepatitis B vaccination programmes. There also appears to be a lack of clear and effective national policies outlining the main axes of infection control targets by 2030. This calls for urgent policy implementation focusing on mandatory vaccination, training, resource availability, adherence to infection control practices and comprehensive post-exposure management.

Exploring the Feasibility and Acceptability of a Telehealth Platform for Older Adults with Noncommunicable Diseases and Chronic Viral Hepatitis.

Background: Telehealth improves access to health care and potentially leads to better clinical outcomes. However, digital competence could be an essential factor in ensuring its adoption, particularly among older adults. This study evaluated the acceptability and perception of a mobile application platform among Thai older patients with chronic diseases according to their demographics and digital skills. Methods: The demographic information and internet usage profiles of patients with nonmalignant chronic diseases, including chronic viral hepatitis, were collected. Participants were grouped based on their self-perceived digital familiarity. The chi-square test was used to evaluate the associations between the parameters. Results: Among 710 participants (61.7% women, mean age: 66.2 years), digital familiarity was significantly higher among individuals aged <70 years, men, those with a bachelor's degree or higher, those with higher incomes, and Bangkok residents (p < 0.001). In this study, regular use of smartphones and the internet, but not messaging applications, was associated with self-perceived digital familiarity. Of these, 100 participants completed a survey evaluating their satisfaction with and perceptions of telehealth. Participants with greater digital familiarity demonstrated significantly higher satisfaction with telemedicine compared with those with limited ability or relied on caretakers (χ2 = 70.145, p < 0.001). Conclusion: Our data indicated that a user-friendly mobile application is feasible and acceptable for the management of chronic diseases in older patients. Digital familiarity is an important factor associated with satisfaction with the platform, underscoring the need to bridge digital skill gaps and ensure equitable health care delivery.

Contemporary Awareness of Viral Hepatitis between 2012 and 2022 among Korean Adults.

Contemporary Awareness of Viral Hepatitis between 2012 and 2022 among Korean Adults.

Coronavirus envelope protein activates TMED10-mediated unconventional secretion of inflammatory factors

The precise cellular mechanisms underlying heightened proinflammatory cytokine production during coronavirus infection remain incompletely understood. Here we identify the envelope (E) protein in severe coronaviruses (SARS-CoV-2, SARS, or MERS) as a potent inducer of interleukin-1 release, intensifying lung inflammation through the activation of TMED10-mediated unconventional protein secretion (UcPS). In contrast, the E protein of mild coronaviruses (229E, HKU1, or OC43) demonstrates a less pronounced effect. The E protein of severe coronaviruses contains an SS/DS motif, which is not present in milder strains and facilitates interaction with TMED10. This interaction enhances TMED10-oligomerization, facilitating UcPS cargo translocation into the ER-Golgi intermediate compartment (ERGIC)—a pivotal step in interleukin-1 UcPS. Progesterone analogues were identified as compounds inhibiting E-enhanced release of proinflammatory factors and lung inflammation in a Mouse Hepatitis Virus (MHV) infection model. These findings elucidate a molecular mechanism driving coronavirus-induced hyperinflammation, proposing the E-TMED10 interaction as a potential therapeutic target to counteract the adverse effects of coronavirus-induced inflammation.

Feasibility and Performance of a Point-of-Care Hepatitis C RNA Assay in a Community Supervision Cohort

This cross-sectional study examines the feasibility and clinical performance of a fingerstick point-of-care hepatitis C virus (HCV) RNA assay in a community supervision (probation or parole) setting.

The association of systemic inflammatory biomarkers with metabolic dysfunction-associated steatotic liver disease and arterial hypertension

Objective — to explore the relationship between metabolic dysfunction‑associated steatotic liver disease (MASLD) on the background of arterial hypertension (AH) and blood inflammatory markers including C‑reactive protein (CRP), Interleukin‑6 (IL‑6), IL‑4, haptoglobin and pentraxin‑3 (PTX‑3). Materials and methods. We examined 102 patients with MASLD. They were divided into 3 groups: group A included 52 patients with isolated MASLD, group B — 23 patients with MASLD and AH stage I, and group C — 27 patients with MASLD and AH stage II. The control group (group D) comprised 20 apparently healthy people. Patients with viral hepatitis, liver cirrhosis, alcoholic liver disease, and AH stage III were excluded. Systemic inflammatory biomarkers analyses were performed using electrochemiluminescence, immunoenzymatic, and immunoturbidimetry techniques. Results. The systemic inflammatory biomarkers analyses revealed significantly higher levels of CRP (p=0.001), IL‑6 (p=0.01), haptoglobin (p&lt;0.05) and PTX‑3 (p&lt;0.01) and decreased levels of IL‑4 (p&lt;0.05) in group B and group C in comparison with the group A and control group (p1 &lt;0.01, p2=0.01). Also, there was a significant increase of CRP (p=0.01), IL‑6 (p=0.01), and PTX‑3 levels (p&lt;0.05) in group B compared with group C. However, the relationship between the IL‑4 (p&gt;0.05) and haptoglobin (p&gt;0.05) levels and the progression of the AH stages have not been confirmed in our study. Conclusions. Our findings indicate the direct relationship between the systemic inflammatory biomarkers’ involvement in developing liver tissue inflammation and the further progression of MASLD. The obtained data indicate the relationship of AH and its stages with the development of chronic systemic inflammatory response in patients with MASLD and AH comorbid course.

Hepatitis B and C viral infections and correlates among pregnant women in Ilorin, Nigeria: a cross-sectional study

Background: Hepatitis B and C are significant viral infections in pregnancy with high risk of maternal and neonatal complications. This study was conducted to determine the prevalence of hepatitis B and C viral infections and correlates among pregnant women who attended antenatal care (ANC) unit of General and Civil Service Hospitals, Ilorin, Nigeria. Methodology: This was a descriptive cross-sectional study of 282 consented pregnant women randomly selected from the ANC units of two hospitals in Ilorin. Blood samples were collected from the pregnant women and tested for hepatitis B virus (HBV) surface antigen (HBsAg) and anti-hepatitis C virus (HCV) antibody using Enzyme Linked Immunosorbent Assay (ELISA) technique. Socio-demographic and obstetrics information of the pregnant women and potential risk factors for HBV and HCV infections were collected using a pretested structured questionnaire. Statistical analysis was done using SPSS version 22.0 Results: Majority of the women were married (78.4%), from monogamous families (57.8%), do not share sharp objects (65.6%), have not received blood transfusion (65.3%), have no history of organ transplantation (91.1%), and multigravida (61.4%,) in their first (36.9%), second (37.2%) and third (25.9%) trimesters of pregnancy. Overall, 22.3% and 1.4% tested positive for HBsAg and anti-HCV respectively. Family background of the study participants showed significant (p˂0.05) association with HBsAg positivity. None of the other analysed variables showed any significant association with both HBsAg and anti-HCV positivity. Conclusion: This result showed high prevalence of HBV but low prevalence of HCV infections among pregnant women in the study setting. Improved surveillance and routine screening for HBV and HCV for women attending ANC is recommended to reduce disease burden and help achieve WHO goal of eliminating viral hepatitis as a major public health threat by 2030.
