ABSTRACT
We diagnosed six cases of acute hepatitis C virus (HCV) infection at our hospital between October 2003 and December 2022. During the same period, we diagnosed 402 cases of chronic HCV infection and 636 cases of acute hepatic injury. Acute HCV infection cases accounted for 1.4% of all HCV infections and 0.9% of all acute hepatic injury cases. The acute HCV infection group was younger, had more severe hepatitis, and exhibited higher levels of bilirubinemia compared to the chronic HCV infection group. Two acute HCV infection cases achieved spontaneous viral clearance, while the remaining four cases progressed to chronic infection and were treated with direct-acting antivirals (DAAs). Liver enzyme elevation and liver function deterioration did not differ significantly between the acute HCV and other acute liver injury groups. Notably, DAA treatment was equally effective for acute and chronic HCV cases (75% vs. 90%, p = 0.34). Early DAA treatment in acute cases might contribute to interrupting viral transmission among high-risk populations, such as people who inject drugs or men who have sex with men. While there are currently no specific guidelines for acute HCV infection treatment in Japan, our findings suggest that DAA therapy should be initiated immediately following diagnosis. Further studies with larger patient cohorts are warranted to confirm these observations.
ABSTRACT
Objective: Multiple observational studies have demonstrated an association between type 2 diabetes mellitus (T2DM) and chronic liver diseases (CLDs). However, the causality of T2DM on CLDs remained unknown in various ethnic groups. Methods: We obtained instrumental variables for T2DM and conducted a two-sample mendelian randomization (MR) study to examine the causal effect on nonalcoholic fatty liver disease (NAFLD), hepatocellular carcinoma (HCC), viral hepatitis, hepatitis B virus (HBV) infection, and hepatitis C virus (HCV) infection risk in Europeans and East Asians. The primary analysis utilized the inverse variance weighting (IVW) technique to evaluate the causal relationship between T2DM and CLDs. In addition, we conducted a series of rigorous analyses to bolster the reliability of our MR results. Results: In Europeans, we found that genetic liability to T2DM has been linked with increased risk of NAFLD (IVW : OR =1.3654, 95% confidence interval [CI], 1.2250-1.5219, p=1.85e-8), viral hepatitis (IVW : OR =1.1173, 95%CI, 1.0271-1.2154, p=0.0098), and a suggestive positive association between T2DM and HCC (IVW : OR=1.2671, 95%CI, 1.0471-1.5333, p=0.0150), HBV (IVW : OR=1.1908, 95% CI, 1.0368-1.3677, p=0.0134). No causal association between T2DM and HCV was discovered. Among East Asians, however, there was a significant inverse association between T2DM and the proxies of NAFLD (ALT: IVW OR=0.9752, 95%CI 0.9597-0.9909, p=0.0021; AST: IVW OR=0.9673, 95%CI, 0.9528-0.9821, p=1.67e-5), and HCV (IVW: OR=0.9289, 95%CI, 0.8852-0.9747, p=0.0027). Notably, no causal association was found between T2DM and HCC, viral hepatitis, or HBV. Conclusion: Our MR analysis revealed varying causal associations between T2DM and CLDs in East Asians and Europeans. Further research is required to investigate the potential mechanisms in various ethnic groups, which could yield new insights into early screening and prevention strategies for CLDs in T2DM patients.

BACKGROUND & AIMS: Widespread use of direct-acting antivirals for hepatitis C virus infection has been paralleled with increased numbers of patients with hepatocellular carcinoma (HCC) after achieving sustained virologic response (post-SVR HCC) worldwide. Few data compare regional differences in the presentation and prognosis of patients with post-SVR HCC. METHODS: We identified patients with advanced fibrosis (F3/F4) who developed incident post-SVR HCC between March 2015 and October 2021 from 30 sites in Europe, North America, South America, the Middle East, South Asia, East Asia, and Southeast Asia. We compared patient demographics, liver dysfunction, and tumor burden by region. We compared overall survival by region using Kaplan-Meier analysis and identified factors associated with survival using multivariable Cox regression analysis. RESULTS: Among 8796 patients with advanced fibrosis or cirrhosis who achieved SVR, 583 (6.6%) developed incident HCC. There was marked regional variation in the proportion of patients detected by surveillance (range: 59.5%-100%), median maximum tumor diameter (range, 1.8-5.0 cm), and the proportion with multinodular HCC (range, 15.4%-60.8%). The prognosis of patients highly varied by region (hazard ratio range, 1.82-9.92), with the highest survival rates in East Asia, North America, and South America, and the lowest survival rates in the Middle East and South Asia. After adjusting for geographic region, HCC surveillance was associated with early stage detection (Barcelona Clinic Liver Cancer stage 0/A, 71.0% vs 21.3%; P < .0001) and lower mortality rates (adjusted hazard ratio, 0.29; 95% CI, 0.18-0.46). CONCLUSIONS: Clinical characteristics, including early stage detection, and prognosis of post-SVR HCC differed significantly across geographic regions. Surveillance utilization appears to be a high-yield intervention target to improve prognosis among patients with post-SVR HCC globally.

Therapy for chronic hepatitis C virus infection with direct-acting antiviral agents (DAAs) has been highly successful in achieving sustained virological response (SVR) with associated improvements in liver dysfunction, liver-related mortality, and transplant-free survival. There is a high risk of hepatocellular carcinoma (HCC) with an annual incidence of 2% to 4% in patients with cirrhosis. Following DAAs treatment and achievement of SVR, the risk of incident and recurrent HCC drops significantly over time, with risk associated with demographic and liver disease-related factors. Several risk factors have been described including age, male, diabetes comorbidities, alcohol abuse, hepatitis B virus or human immunodeficiency virus-coinfection, and advanced liver disease or increased liver fibrosis. Recurrence risk after DAA therapy has been associated with baseline tumor burden, with increased risk with larger lesion(s), multifocal disease, elevated alpha-fetoprotein level, treatment type (curative vs palliative), and shorter interval between HCC complete response and DAA initiation. Overall, due to the heterogeneity among individual patient data and lack of adequately controlled data, there are no conclusive statements that can be drawn that DAAs exposure is directly associated with HCC occurrence or recurrence. However, the best available data suggest a decreased risk of incident HCC with DAA therapy and no increased risk of recurrence with DAAs after complete tumor response.

ABSTRACT Background: Spontaneous regression (SR) is defined as the partial or complete disappearance of a tumor, in the absence of a specific treatment. Evidence of the SR in hepatocellular carcinoma (HCC) is rare. Objective: The authors aimed to review all the cases of SR of HCC in two reference centers of Southern Brazil, highlighting the main characteristics. Methods: Data of all patients with HCC were retrospectively reviewed looking for the occurrence of SR in patients from two tertiary centers in Southern Brazil, in the last five years. The diagnosis of cirrhosis was established according to clinical, laboratory and imaging data, as well as upper endoscopy or histopathological examination when necessary. The diagnosis of HCC was based on typical findings according to radiologic criteria (LIRADS) or histopathological examination. Spontaneous regression was defined as a partial or complete involution of a HCC in the absence of a specific therapy. Results: From all cases of HCC in the last 5 years (n=433), there were five cases of SR. Three (60%) were men, the mean age was 62.6 (50.0-76.0) years, and the etiology was HCV in 3 (60%). Complete regression was observed in three patients (60%), one patient (20%) presented partial regression, and one (20%) relapesed and died. The time of follow-up varied between 12 and 21 months. In this presentation, it was highlighted one case of SR observed after COVID-19 infection in a patient with cirrhosis. The possible mechanisms involved in this situation were reviewed, emphasizing the most common like hypoxia and immunological. There were also one patient submitted to a surgical procedure as a possible fator involved and three patients without obvious risk factors. Conclusion: This phenomenon will possibly contribute to a better understanding of the pathophysiological mechanisms of HCC.
RESUMO Contexto: A evidência da regressão espontânea (RE) no carcinoma hepatocelular (CHC) é rara. Objetivo: Revisar todos os casos de RE de CHC em dois centros de referência do Sul do Brasil, destacando as principais características. Métodos: Os dados de todos os pacientes com CHC foram revisados retrospectivamente buscando a ocorrência de RE em pacientes de dois centros terciários do Sul do Brasil, nos últimos 5 anos. O diagnóstico de cirrose foi estabelecido de acordo com dados clínicos, laboratoriais e de imagem, além de endoscopia digestiva alta ou exame histopatológico quando necessário. O diagnóstico de CHC foi baseado em achados típicos de acordo com critérios radiológicos (LIRADS) ou exame histopatológico. A RE foi definida como uma involução parcial ou completa de um CHC na ausência de terapia específica. Resultados: Do total de casos de CHC nos últimos 5 anos (n=433), houve cinco casos de RE. Três (60%) eram homens, a média de idade foi de 62,6 (50,0-76,0) anos, a etiologia foi virus da hepatite C em 3 (60%). A regressão completa foi observada em três pacientes (60%), um paciente (20%) apresentou regressão parcial e um (20%) apresentou recidiva e evoluiu a óbito. O tempo de seguimento variou entre 12 e 21 meses. Nesta apresentação foi destacado um caso (20%) de RE observado após infecção por COVID-19 em paciente com cirrose. Foram revisados os possíveis mecanismos envolvidos nesta situação, enfatizando os mais comuns como hipóxia e imunológicos. Houve também um paciente submetido a procedimento cirúrgico como possível fator envolvido e três pacientes sem fatores de risco evidentes. Conclusão: Este fenômeno possivelmente contribuirá para uma melhor compreensão dos mecanismos fisiopatológicos do CHC.
ABSTRACT
INTRODUCTION: Eradication of HCV in the global population remains one of the greatest challenges faced by the WHO. An insufficient level of knowledge and the lack of a national screening test strategy are obstacles to HCV eradication. AIM: This work aimed to summarize surveys assessing risk factors and awareness of the respondents regarding the prevention and course of HCV infection. The summary also includes the most important European and global attempts at eliminating HCV. MATERIALS AND METHODS: A cross-sectional, population-based study was conducted in the Mazowieckie district in Poland using anonymous surveys and conducted on people who willingly reported for a test. RESULTS: In the study cohort of n = 7397 adults, there were 5412 women (73.16%). The analysis of the quota sample (n = 1303) reflected the actual proportions in the population of the Mazowieckie Voivodeship. CONCLUSIONS: Insufficient knowledge about HCV decreases the probability of higher detection of infections, fast diagnostics, and treatment. According to the WHO model, assuming a 90% detection rate and treatment of 80% of infected by 2030, and taking into account 120-150 thousand infected persons in Poland, the number of detections of HCV should be increased 4-5 times and all diagnosed persons should be offered antiviral treatment.

ATPase family AAA domain-containing protein 1 (ATAD1) maintains mitochondrial homeostasis by removing mislocalized tail-anchored (TA) proteins from the mitochondrial outer membrane (MOM). Hepatitis C virus (HCV) infection induces mitochondrial fragmentation, and viral NS5B protein is a TA protein. Here, we investigate whether ATAD1 plays a role in regulating HCV infection. We find that HCV infection has no effect on ATAD1 expression, but knockout of ATAD1 significantly enhances HCV infection; this enhancement is suppressed by ATAD1 complementation. NS5B partially localizes to mitochondria, dependent on its transmembrane domain (TMD), and induces mitochondrial fragmentation, which is further enhanced by ATAD1 knockout. ATAD1 interacts with NS5B, dependent on its three internal domains (TMD, pore-loop 1, and pore-loop 2), and induces the proteasomal degradation of NS5B. In addition, we provide evidence that ATAD1 augments the antiviral function of MAVS upon HCV infection. Taken together, we show that the mitochondrial quality control exerted by ATAD1 can be extended to a novel antiviral function through the extraction of the viral TA-protein NS5B from the mitochondrial outer membrane.

Disease management in challenging patient population with cancer and concomitant serious conditions presents an unmet clinical need. The major gap is the lack of data from properly designed trials that could support clinical decisions. Despite many advances in the fields of oncology, immunology, and infectious diseases, chronic viral infections in cancer patients remain to some extent terra incognita. Therefore, many patients lose the opportunity to receive the most advanced therapy, and physicians are compelled to make treatment decisions without sufficient evidence. In this review, we discuss the utility of immunotherapy in patients with chronic hepatitis C viral infection. Limited data from several studies and case reports support the hypothesis that immune checkpoint inhibitors can be used safely and effectively in this patient population. Available results warrant further investigation of immunotherapy in infected patients. Taking into account the current state of our knowledge, expanding clinical trial eligibility should be considered by investigators and sponsors to allow patient access to novel therapies and better matching of clinical research to the real-world population.

Current HCV prevention efforts and treatment rates must improve for the United States (U.S.) to achieve WHO global elimination targets by 2030[1]. The current multi-day diagnosis and treatment paradigm for hepatitis C (HCV) infection leads to significant loss in the cascade of care, resulting in far fewer patients receiving treatment with direct acting antiviral agents (DAAs) than those diagnosed with HCV infection [2,3]. To achieve HCV elimination, a paradigm shift in access to HCV treatment is needed from current multi-day testing and treatment algorithms to same day diagnosis and treatment. This shift will require new tools, such as FDA-approved, CLIA-waived point-of-care (POC) antigen or nucleic acid tests (NAT) for HCV and HBV and NAT for HIV that do not require venous blood. Such a shift will also require better utilization of existing resources, expanding access to HCV treatment through availability of onsite treatment, removal of payer barriers to approval, adoption of minimal monitoring approaches during treatment, expanded access to available POC tests, and available specialist referral networks for patients who fail initial therapy, have advanced liver fibrosis, or have co-incident HIV or HBV infection. A same-day diagnosis and treatment paradigm will substantially contribute to HCV elimination by improving treatment rates for those diagnosed with HCV infection and expanding access to treatment in settings where patients have brief encounters with healthcare.
ABSTRACT
Dysregulation of iron metabolism in chronic hepatitis C (CHC) is a significant risk factor for hepatic cirrhosis and cancer. We studied if known genetic variants related to iron homeostasis associate with liver disease progression in CHC. Retrospective analysis included 249 CHC patients qualified for antiviral therapy between 2004 and 2014. For all patients, nine SNPs within HFE, TFR2, HDAC2, HDAC3, HDAC5, TMPRSS6, and CYBRD1 genes were genotyped. Expression of selected iron-related genes, was determined with qRT-PCR in 124 liver biopsies, and mRNA expression of co-inhibitory receptors (PD-1, Tim3, CTLA4) was measured in 79 liver samples. CYBRD1 rs884409, HDAC5 rs368328, TFR2 rs7385804, and TMPRSS6 rs855791 associated with histopathological changes in liver tissue at baseline. The combination of minor allele in HDAC3 rs976552 and CYBRD1 rs884409 linked with higher prevalence of hepatocellular carcinoma (HCC) during follow up (OR 8.1 CI 2.2-29.2; p = 0.001). Minor allele in HDAC3 rs976552 associated with lower hepatic expression of CTLA4. Tested polymorphisms related to iron homeostasis associate with histopathological changes in the liver. The presence of both HDAC3 rs976552 G and CYBRD1 rs884409 G alleles correlates with HCC occurrence, especially in the group of patients with elevated AST (>129 IU/L). rs976552 in HDAC3 could impact immunological processes associated with carcinogenesis in CHC.

Although most patients with hepatitis C virus (HCV) infection have been cured since the introduction of direct-acting antiviral (DAA) treatments, whether patients with psychiatric disorders and chronic HCV infection receive benefits from DAA treatments remain unclear. The efficacy and safety of DAA treatment were compared between patients with and without psychiatric disorders. Data were retrospectively collected from medical records at the Suzuka General Hospital (Japan) between September 2014 and December 2021. The study was an observational, single-center study. Fisher's exact test, Mann-Whitney U test and Friedman's test were used for the comparisons between groups. Patients with HCV infection who had been started on DAA treatments were included. In total, 15 HCV cases with psychiatric disorders (P) and 209 HCV cases with nonpsychiatric disorders (NP) were started on DAA treatments for HCV infection. Patients in group P were younger (55±13.9 years) compared with those in group NP (68±13.0 years). A total of 12 patients (80%) in group P achieved and 188 patients (90%) in group NP achieved sustained virologic response (SVR), with no significant difference between the two groups. The remaining three patients in group P who did not achieve SVR included two drop-out cases. Regarding the laboratory data at the end of DAA treatments and SVR, there were no significant differences between the two groups. There were no cases of discontinuation or reduction of medication due to psychiatric disorders during DAA treatment. DAA treatment for HCV infection is effective, tolerable and safe for psychiatric patients, as well as patients without psychiatric disorders. Psychiatric patients with HCV infection should undergo DAA treatment to prevent progression to liver failure and/or cancer.
ABSTRACT
We studied the trends in liver cancer-related mortality before and during the COVID-19 pandemic. Quarterly age-standardized mortality and quarterly percentage change (QPC) for hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC) were estimated using the US national mortality database 2017-2021. Quarterly age-standardized mortality from HCC decreased steadily with an average QPC of -0.4% (95% confidence interval [CI]: -0.6% to -0.2%). A decrease in hepatitis C virus and hepatitis B virus-related HCC mortality of -2.2% (95% CI: -2.4% to -1.9%) and -1.1% (95% CI: -2.0% to -0.3%) was noted. In contrast, mortality for HCC from nonalcoholic fatty liver disease (3.0%, 95% CI: 2.0%-4.0%) and alcohol-related liver disease (1.3%, 95% CI: 0.8%-1.9%) demonstrated a linear increase. There was a linear increase in the quarterly age-standardized ICC-related mortality (0.8%, 95% CI: 0.5%-1.0%). While ICC-related mortality continued to increase, HCC-related mortality tended to decline mainly due to a decline in mortality due to viral hepatitis.

BACKGROUND: No study has evaluated the effect of hepatitis C virus (HCV) infection on the wide spectrum of complications affecting patients with thalassemia. OBJECTIVES: This multicenter study prospectively assessed the relationship of HCV infection with diabetes mellitus and cardiovascular complications in patients with thalassemia major (TM). METHODS: We considered 1057 TM patients (539 females; 29.79±10.08 years) enrolled in the MIOT Network and categorized into 4 groups: negative patients (group 1a, N=460), patients who spontaneously cleared the virus within 6months (group 1b, N=242), patients who eradicated the virus after the treatment with antiviral therapy (group 2, N=102), and patients with chronic HCV infection (group 3, N=254). RESULTS: Group 1a and 1b were considered as a unique group (group 1). For both groups 1 and 3, a match 1:1 for age and sex with group 2 was performed. The effective study cohort consisted of 306 patients (three groups of 102 patients). During a mean follow-up of 67.93±39.20months, the group 3 experienced a significantly higher % increase/month in aspartate transaminase levels and left ventricular mass index than both groups 1 and 2. The changes in iron overload indexes were comparable among the three groups. Compared to group 1, the chronic HCV group showed a significantly higher risk of diabetes (hazard ratio-HR=5.33; p=0.043) and of cardiovascular diseases (HR=3.80; p=0.034). CONCLUSION: Chronic HCV infection is associated with a significant higher risk of diabetes mellitus and cardiovascular complications in TM patients and should be approached as a systemic disease in which extrahepatic complications increase the weight of its pathological burden.

The clinical use of direct-acting antivirals (DAAs) for hepatitis C virus (HCV) infection has dramatically changed management of patients with HCV liver disease since 2014; this is also true for patients undergoing dialysis. Due to the high tolerability and antiviral efficacy of anti-HCV therapy, most dialysis patients with HCV infection should currently be candidates for this treatment. Many patients with HCV antibodies no longer have HCV infection, and it is difficult to identify patients with actual HCV infection based only on HCV antibody assays. Despite the high rate of successful HCV eradication, the risk of liver-related events such as hepatocellular carcinoma (HCC), the major complication of HCV infection, persists even after HCV cure, and patients at risk of HCC should undergo continuous HCC surveillance. Finally, the rarity of HCV reinfection and the survival benefit of HCV eradication in dialysis patients should be explored in further studies.

Background and Objectives: The global prevalence of chronic hepatitis C virus (HCV) infection is 0.8%, affecting around 58 million people worldwide. Treatment with DAAs reduces all-cause HCV mortality by 49-68%. This work aims to determine whether there is liver fibrosis regression (LFR) in patients who achieved Sustained Virological Response (SVR) after treatment with DAAs. Materials and Methods: An analytical, observational, single-center, and cohort study was carried out. The final sample consisted of 248 HCV-infected patients. All started treatment with DAAs between January 2015 and December 2017. Five measurements were performed to determine the fibrotic stage in patients (measured in kilopascals (kPa)) using transient elastography (FibroScan®, Echosens, The Netherlands). Results: Taking the baseline fibrotic stage as a reference, the distribution in subgroups was as follows: 77 F4 patients (31.0%); 55 F3 patients (22.2%); 53 F2 patients (21.4%); and 63 F0/F1 patients (25.4%). There were 40 patients (16.1%) with at least one HCV complication and 13 (5.2%) who developed hepatocellular carcinoma. The overall LFR rate was 77.8% (144 of 185 F2/F3/F4 patients, p = 0.01) at the end of the follow-up period. The highest mean FibroScan® values were observed in patients with: "male gender"; "metabolic syndrome"; "subtype 1a"; "NRP DAA"; "at least one HCV complication"; "death from HCV complications"; and "liver transplantation requirement". Conclusions: Treatment with DAAs achieved high rates of LFR and a decrease in mean FibroScan® values in all subgroups.

BACKGROUND: Most people who inject drugs (PWIDs) suffer from severe fatigue, and chronic hepatitis C virus (HCV) infection may play a role in this. However, there is scarce evidence about interventions that alleviate fatigue among PWIDs. The present study investigated the effect of integrated HCV treatment on fatigue in this population compared to the effect of standard HCV treatment, adjusted for sustained virological response of the HCV treatment. METHODS: This multi-center, randomized controlled trial evaluated fatigue as a secondary outcome of integrated HCV treatment (the INTRO-HCV trial). From May 2017 to June 2019, 276 participants in Bergen and Stavanger, Norway, were randomly assigned to receive integrated and standard HCV treatment. Integrated treatment was delivered in eight decentralized outpatient opioid agonist therapy clinics and two community care centers; standard treatment was delivered in specialized infectious disease outpatient clinics at referral hospitals. Fatigue was assessed prior to treatment and 12 weeks after treatment using the nine-item Fatigue Severity Scale (FSS-9). We applied a linear mixed model to evaluate the impact of integrated HCV treatment on changes in FSS-9 (ΔFSS-9) sum scores. RESULTS: At baseline, the mean FSS-9 sum score was 46 (standard deviation (SD): 15) for participants on integrated HCV treatment and 41 (SD: 16) for those on standard treatment. Twelve weeks after completed HCV treatment, the mean FSS-9 sum score for participants receiving integrated HCV treatment was 42 (SD: 15) and 40 (SD: 14) for those receiving standard HCV treatment. Integrated HCV treatment did not reduce the FSS-9 scores compared to standard HCV treatment (ΔFSS-9: -3.0, 95% confidence interval (CI): -6.4;0.4). CONCLUSIONS: Fatigue is a common symptom among PWIDs. Integrated HCV treatment is at least equal to standard HCV treatment in improving fatigue.

A 72-year-old woman had a history of chronic hepatitis C virus (HCV) infection previously treated with interferon to achieve a sustained virologic response. Thereafter, she developed polyarthritis and purpura of the lower extremities as well as progressive renal dysfunction with hypertension and proteinuria that had occurred in the last three months. Laboratory investigations revealed seropositivity for cryoglobulin but negative findings for HCV RNA. She was ultimately diagnosed with cryoglobulinemic glomerulonephritis complicated by monoclonal gammopathy of undetermined significance (MGUS) based on the pathological findings of the kidney and bone marrow, indicating that MGUS-induced cryoglobulinemic vasculitis may occur even after HCV elimination.

OBJECTIVES: Patients with chronic hepatitis C virus (HCV) infection have a genuine risk of developing liver fibrosis and cirrhosis, potentially resulting in hepatocellular carcinoma (HCC), a risk that remains even after sustained viral response (SVR). Glycomics-based biomarkers are an attractive tool to closely monitor these patients during and after antiviral treatment, as alterations in the abundance of N-glycans reflect an altered state of the liver. This study assessed serum glycomics for the evaluation of inflammation-related fibrosis regression during and after treatment of HCV with DAAs. METHODS: The GlycoFibroTest and GlycoCirrhoTest were analyzed in the sera 36 HCV-infected patients with advanced fibrosis (F3) or established cirrhosis (F4), before (week 0), during (week 12) and after (week 24) a twelve-week oral administration of DAAs therapy - using an optimized glycomic technology on a DNA sequencer. RESULTS: All patients achieved SVR after treatment and two of them developed HCC in the subsequent five years. A significant decrease of the GlycoFibroTest (p < 0.0001) was seen after 12 weeks, consistent with other measured biomarkers (APRI, FIB-4, FibroTest). Statistical analysis was performed in IBM SPSS Statistics version 28.0, using the non-parametric Friedman's test with a statistical significance α level of 0.05. CONCLUSION: This study suggests that the GlycoFibroTest is a serum biomarker for viral response in HCV patients. The rapid decrease of the glycomics-based biomarker probably reflects the amelioration of liver inflammation as underlying process, rather than the improvement of liver fibrosis itself.

Background@#The association between hepatitis C virus (HCV) infection and chronic kidney disease (CKD) still remains controversial. We aimed to investigate whether HCV really affects renal function, and to analyze the association between clinical effects of CHC and decreased kidney function (assessed by glomerular filtration rate (eGFR) level).@*Aim@#Study of renal dysfunction in chronic hepatitis C virus infection@*Materials and Methods@#An estimated 222 patients with HCV infection and 222 age- and sex-matched community-based control individuals without HCV were enrolled (1:1, case and control ratio) in this study between from June 2022 to March 2023. We used the modification of diet in renal diseases to calculate eGFR. This study was approved by the review board of the Ethics Subcommittee of Ach Medical University and followed the Declaration of Helsinki. All statistical analysis was performed with SPSS version 26.0 software (SPSS Inc., Chicago, IL, USA), and a P value < 0.05 was considered statistically significant. Continuous variebles were presented as mean ± standard deviation, while categorical data was represented as numbers and percentages. Independent t-tests were used to compare the differences in parametric variables. The Mann-Whitney U test was performed to compare the follow-up period. Pearson’s chi-squared and Fisher’s exact tests were used to compare categorical variables. Multivariate logistic regression was used to identify the risk factors associated with recurrence. @*Results@#The median age of the respondents was 40 (range 21-70). In the case group, the speed of hanging judgment was 105.3±24.5, and in the control group, it was 118.7±18.5, which was a statistically significant difference (p<0.05, p<0.05). It was observed that the rate of filtration of the renal is below 90 or the loss of renal function increases with age (47.50±9.3 vs 40.21±11.1; p<0.01). In order to reduce the effect of age, when evaluating the renal function of participants over 45 years of age in the case-control group, the HCV was 99.69 in the case group and 111.05 in the control group, although there was an age effect on the decline in HCV in both groups, but it decreased more in the HCV-infected group. When comparing two groups (<3.25, >3.25) with liver fibrosis degree above and below 3.25, the higher degree of fibrosis affects the decrease in the rate of hepatic filtration (112.92±19.8 vs 105.23±27.1; p<0.01). The proportion of cryoglobulinemia was high when renal dysfunction was beginning or when the GFR was below 90 (<90). Logistic regression analysis showed that cryoglobulinemia had the greatest influence on the decrease in glomerular filtration rate (OR 4.22, 95% CI 1.97-9.00, p<0.05). The relationship between age and the decline in hanging judgment speed was statistically significant and directly moderate (r=0.95, p=0.009). On the other hand, there is a statistical relationship between gender and the decrease in the speed of hanging judgment, with a probable and weak correlation (r=0.07, p=0.01).@*Conclusion@#Our study found that the patients with HCV infection are associated with a low eGFR compared with non-HCV–infected patients. This association is consistent in age, gender, cryoglobulinemia and liver fibrosis patients.
ABSTRACT
Background: Hepatitis C virus infection as it specifically relates to pregnancy has been a neglected condition, thus its recognition and treatment in pregnancy is relevant because of the risks of the long-term complications of the infection in the mother, potential effects of the infection on the pregnancy and risk of vertical transmission to the newborn. Objectives: To determine the proportion of pregnant women with serologic markers of hepatitis C infection, identify risk factors as well as factors that predict the occurrence of the infection in them. Methodology: Over a 3-week period, blood samples from 456 pregnant women were assessed for antibodies to hepatitis C virus, while a pre-tested questionnaire was used to obtain socio-demographic data and the presence of risk factors in the University of Uyo Teaching Hospital, Nigeria. Results: The prevalence of HCV infection in pregnancy was 4.6%. No known risk factors for HCV infection in pregnancy were identified. Only increasing gestational age was a predictor of HCV infection in pregnancy in the study. Conclusion: The prevalence of hepatitis virus infection among the study population was high. Second trimester and increasing gravidity were protective of the infection in pregnancy. There is therefore need for introduction of general routine screening of all pregnant women presenting for antenatal care.
