Autoimmune hepatitis and primary sclerosing cholangitis after direct-acting antiviral treatment for hepatitis C virus:A case report

BACKGROUND Chronic hepatitis C virus(HCV)infection is a major global health concern that leads to liver fibrosis,cirrhosis,and cancer.Regimens containing direct-acting antivirals(DAAs)have become the mainstay of HCV treatment,achieving a high sustained virological response(SVR)with minimal adverse events.CASE SUMMARY A 74-year-old woman with chronic HCV infection was treated with the DAAs ledipasvir,and sofosbuvir for 12 wk and achieved SVR.Twenty-four weeks after treatment completion,the liver enzyme and serum IgG levels increased,and antinuclear antibody became positive without HCV viremia,suggesting the development of autoimmune hepatitis(AIH).After liver biopsy indicated AIH,a definite AIH diagnosis was made and prednisolone was initiated.The treatment was effective,and the liver enzyme and serum IgG levels normalized.However,multiple strictures of the intrahepatic and extrahepatic bile ducts with dilatation of the peripheral bile ducts appeared on magnetic resonance cholangiopancreatography after 3 years of achieving SVR,which were consistent with primary sclerosing cholangitis.CONCLUSION The potential risk of developing autoimmune liver diseases after DAA treatment should be considered.

Shear-wave elastography to predict hepatocellular carcinoma after hepatitis C virus eradication:A systematic review and meta-analysis

BACKGROUND Direct-acting antiviral agents(DAAs)are highly effective treatment for chronic hepatitis C(CHC)with a significant rate of sustained virologic response(SVR).The achievement of SVR is crucial to prevent additional liver damage and slow down fibrosis progression.The assessment of fibrosis degree can be performed with transient elastography,magnetic resonance elastography or shear-wave elastography(SWE).Liver elastography could function as a predictor for hepato-cellular carcinoma(HCC)in CHC patients treated with DAAs.AIM To explore the predictive value of SWE for HCC development after complete clearance of hepatitis C virus(HCV).METHODS A comprehensive literature search of clinical studies was performed to identify the ability of SWE to predict HCC occurrence after HCV clearance.In accordance with the study protocol,a qualitative and quantitative analysis of the evidence was planned.RESULTS At baseline and after 12 wk of follow-up,a trend was shown towards greater liver stiffness(LS)in those who go on to develop HCC compared to those who do not[baseline LS standardized mean difference(SMD):1.15,95%confidence interval(95%CI):020-2.50;LS SMD after 12 wk:0.83,95%CI:0.33-1.98].The absence of a statistically significant difference between the mean LS in those who developed HCC or not may be related to the inability to correct for confounding factors and the absence of raw source data.There was a statist-ically significant LS SMD at 24 wk of follow-up between patients who developed HCC vs not(0.64;95%CI:0.04-1.24).CONCLUSION SWE could be a promising tool for prediction of HCC occurrence in patients treated with DAAs.Further studies with larger cohorts and standardized timing of elastographic evaluation are needed to confirm these data.

Ensemble for evaluating diagnostic efficacy of non-invasive indices in predicting liver fibrosis in untreated hepatitis C virus population

BACKGROUND Hepatitis C virus(HCV)infection progresses through various phases,starting with inflammation and ending with hepatocellular carcinoma.There are several invasive and non-invasive methods to diagnose chronic HCV infection.The invasive methods have their benefits but are linked to morbidity and complications.Thus,it is important to analyze the potential of non-invasive methods as an alternative.Shear wave elastography(SWE)is a non-invasive imaging tool widely validated in clinical and research studies as a surrogate marker of liver fibrosis.Liver fibrosis determination by invasive liver biopsy and non-invasive SWE agree closely in clinical studies and therefore both are gold standards.AIM To analyzed the diagnostic efficacy of non-invasive indices[serum fibronectin,aspartate aminotransferase to platelet ratio index(APRI),alanine aminotransferase ratio(AAR),and fibrosis-4(FIB-4)]in relation to SWE.We have used an Artificial Intelligence method to predict the severity of liver fibrosis and uncover the complex relationship between non-invasive indices and fibrosis severity.METHODS We have conducted a hospital-based study considering 100 untreated patients detected as HCV positive using a quantitative Real-Time Polymerase Chain Reaction assay.We performed statistical and probabilistic analyses to determine the relationship between non-invasive indices and the severity of fibrosis.We also used standard diagnostic methods to measure the diagnostic accuracy for all the subjects.RESULTS The results of our study showed that fibronectin is a highly accurate diagnostic tool for predicting fibrosis stages(mild,moderate,and severe).This was based on its sensitivity(100%,92.2%,96.2%),specificity(96%,100%,98.6%),Youden’s index(0.960,0.922,0.948),area under receiver operating characteristic curve(0.999,0.993,0.922),and Likelihood test(LR+>10 and LR-<0.1).Additionally,our Bayesian Network analysis revealed that fibronectin(>200),AAR(>1),APRI(>3),and FIB-4(>4)were all strongly associated with patients who had severe fibrosis,with a 100% probability.CONCLUSION We have found a strong correlation between fibronectin and liver fibrosis progression in HCV patients.Additionally,we observed that the severity of liver fibrosis increases with an increase in the non-invasive indices that we investigated.

Immunological crossroads:The intriguing dance between hepatitis C and autoimmune hepatitis

Delving into the immunological crossroads of liver diseases,this editorial explores the dynamic interplay between hepatitis C virus(HCV)and autoimmune hepatitis(AIH).While HCV primarily manifests as a viral infection impacting the liver,previous studies unveil a captivating connection between HCV and the emergence of AIH.The dance of the immune system in response to HCV appears to set the stage for an intriguing phenomenon-an aberrant autoimmune response leading to the onset of AIH.Evidence suggests a heightened presence of autoimmune markers in individuals with chronic HCV infection,hinting at a potential overlap between viral and autoimmune liver diseases.Navigating the intricate terrain of viral replication,immune response dynamics,and genetic predisposition,this editorial adds a layer of complexity to our understanding of the relationship between HCV and AIH.In this immunological crossroads,we aim to unearth insights into the complex interplay,using a compelling case where AIH and primary sclerosing cholangitis overlapped following HCV treatment with direct-acting antivirals as background.

Bridging the gap: Addressing disparities in hepatitis C screening, access to care, and treatment outcomes

Hepatitis C virus(HCV)is a significant public health challenge globally,with substantial morbidity and mortality due to chronic liver disease.Despite the availability of highly effective and well-tolerated direct-acting antiviral therapies,widespread disparities remain in hepatitis C screening,access to treatment,linkage to care,and therapeutic outcomes.This review article synthesizes evi-dence from various studies to highlight the multifactorial nature of these dispari-ties,which affects ethnic minorities,people with lower socioeconomic status,in-dividuals with substance use disorders,and those within correctional facilities.The review also discusses policy implications and targeted strategies needed to overcome barriers and ensure equitable care for all individuals with HCV.Recom-mendations for future research to address gaps in knowledge and evaluation of the effectiveness of interventions designed to reduce disparities are provided.

Expanding the liver donor pool worldwide with hepatitis C infected livers, is it the time?

Liver transplantation(LT)provides a life-saving option for cirrhotic patients with complications and hepatocellular carcinoma.Despite the increasing number of liver transplants performed each year,the number of LT candidates on the waitlist remains unchanged due to an imbalance between donor organ supply and the demand which increases the waitlist time and mortality.Living donor liver transplant had a great role in increasing the donor pool and shortened waitlist time for LT candidates.Nevertheless,further strategies can be implemented to increase the pool of potential donors in deceased donor LT,such as reducing the rate of organ discards.Utilizing hepatitis C virus(HCV)seropositive liver grafts is one of the expanded donor organ criteria.A yearly increase of hundreds of transplants is anticipated as a result of maximizing the utilization of HCV-positive organs for HCV-negative recipients.Direct-acting antiviral therapy's efficacy has revolutionized the treatment of HCV infection and the use of HCV-seropositive donors in transplantation.The American Society of Transplantation advises against performing transplants from HCV-infected liver donors(D+)into HCV-negative recipient(R-)unless under Institutional Review Board-approved study rules and with full informed consent of the knowledge gaps associated with such transplants.Proper selection of patients to be transplanted with HCV-infected grafts and confirming their access to direct-acting antivirals if needed is im-portant.National and international consensuses are needed to regulate this process to ensure the maximum benefit and the least adverse events.

Glecaprevir/pibrentasvir+sofosbuvir for post-liver transplant recurrent hepatitis C virus treatment

Glecaprevir/pibrentasvir in combination with sofosbuvir may serve as a safe and effective option for treatment of recurrent hepatitis C virus post-liver transplant in patients who previously failed direct-acting antivirals.

Hepatitis C virus treatment with glecaprevir and pibrentasvir in patients co-prescribed carbamazepine:Three case reports

BACKGROUND Highly effective and well-tolerated direct-acting antiviral(DAA)therapies have revolutionised the management of hepatitis C virus(HCV);however,niche populations face treatment barriers.DAAs co-prescribed with several firstgeneration anti-epileptic drugs(AEDs)are contraindicated due to drug-drug interactions.A common example is carbamazepine whereby steady-state carbamazepine reduces the maximum concentration and area under the curve of velpatasvir,glecaprevir and pibrentasvir due to potent cytochrome P450(CYP)3A4 induction.Carbamazepine also induces P-glycoprotein which reduces glecaprevir and pibrentasvir’s area under curve to infinite time.Sofosbuvirvelpatasvir and glecaprevir-pibrentasvir are contraindicated in patients who are co-prescribed carbamazepine due to the risk of reduced DAA therapeutic effect and consequently,virological treatment failure.This presents a challenge for patients in whom carbamazepine substitution is medically unfeasible,impractical or unacceptable.However,the properties of current generation DAA therapies,including high-potency non-structural protein 5A inhibitory effect,may be sufficient to overcome reduced bioavailability arising from carbamazepine related CYP 3A4 and P-glycoprotein induction.CASE SUMMARY We present a case series of three patients with non-cirrhotic,treatment-naïve,genotype 1a,1b,and 3a HCV who were treated with a 12 wk course of glecaprevir-pibrentasvir,while co-prescribed carbamazepine for seizure disorders.Glecaprevir-pibrentasvir combination therapy was chosen due to its potent in vitro activity and low barrier to pan-genotypic resistance associated variants.DAA therapy was dose-separated from carbamazepine to maximise time to peak concentration,and taken with meals to improve absorption.Sustained virological response at 12 wk was achieved in each patient with no adverse outcomes.CONCLUSION DAA therapies,including glecaprevir-pibrentasvir,warrant consideration as a therapeutic agent in people with HCV who are co-prescribed carbamazepine,particularly if AED substitution is not feasible.

Sequencing of hepatitis C virus cDNA with polymerase chain reaction directed sequencing *

AIM To explore a rapid and easy sequencing method for hepatitis C virus (HCV) genome, and establish a new sequencing method in China. METHODS Polymerase Chain Reaction (PCR) was combined with DNA sequencing technique. PCR products were purified by agarose gel electrophoresis, polyacrylamide gel electrophoresis (PAGE), Polyethylene glycol (PEG) respectively. Then in the presence of a 5′ labeling PCR primer, purified PCR products were directly sequenced. By this method, HCV NS5b cDNA from two HCV infected individuals (HC 42 and HC 49) were sequenced.

Decade of optimizing therapy with direct-acting antiviral drugs and the changing profile of patients with chronic hepatitis C

Chronic infection with the hepatitis C virus(HCV)remains a major health problem affecting approximately 58 million people worldwide.In the era of interferon(IFN)-based regimens,patients particularly infected with genotypes 1 and 4 achieved a low response rate.The implementation of direct-acting antivirals changed the landscape of HCV treatment.The increase in effectiveness provided us with the hope of eliminating HCV as a significant public threat by 2030.In the following years,there was an observed improvement in the treatment of HCV with genotype-specific regimens and highly effective pangenotypic options that are the most recent stage of the revolution.The optimization of therapy was accompanied by changes in the patient profile from the beginning of the IFN-free era over time.Patients treated with antiviral therapies were younger in successive periods,less burdened with comorbidities and comedications,more frequently treatment-naïve and had less advanced liver disease.Before the IFN-free era,specific subpopulations such as patients with HCV/HIV coinfection,those with a history of previous treatment,patients with renal impairment or with cirrhosis had lower chances for a virologic response.Currently,these populations should no longer be considered difficult to treat.Despite the high effectiveness of HCV therapy,there is a small percentage of patients with treatment failure.However,they can be effectively retreated with pangenotypic rescue regimens.

Stages of care for patients with chronic hepatitis C at a hospital in southern Brazil

BACKGROUND Hepatitis C virus(HCV)is defined as a public health problem by the World Health Organization(WHO)and since then has defined targets through the HCV elimination.The HCV cascade of care highlights the progress towards these goals and essential interventions that need to be delivered along this continuum care.AIM To document the treatment cascade for patients with HCV infection at the Hospital Nossa Senhora da Conceição(HNSC),defining the percentage of antibody-positive patients who collected molecular biology tests(polymerase chain reaction),attended outpatient clinic assistance,underwent treatment,and achieved a virologic cure termed sustained virologic response(SVR).METHODS With the retrospective cohort design,patients diagnosed with HCV infection in the period between January 1,2015 and December 31,2020 were included.Data from HCV notification forms,electronic medical records,Computerized Laboratory Environment Manager System,and Medicine Administration System(evaluation of special medications)were collected in 2022 and all information up to that period was considered.The data were analyzed with IBM SPSS version 25,and Poisson regression with robust simple variance was performed for analysis of variables in relation to each step of the cascade.Variables with P<0.20 were included in the multivariate analysis with P<0.05 considered significant.Pearson’s chi-square test was applied to compare the groups of patients who persisted in follow-up at the HNSC and who underwent follow-up at other locations.RESULTS Results were lower than expected by the WHO with only 49%of candidates receiving HCV treatment and only 29%achieving SVR,despite the 98%response rate to direct acting antivirals documented by follow-up examination.The city of origin and the place of follow-up were the variables associated with SVR and all other endpoints.When comparing the cascade of patients who remained assisted by the HNSC vs external patients,we observed superior data for HNSC patients in the SVR.Patients from the countryside and metropolitan region were mostly assisted at the HNSC and the specialized and continuous care provided at the HNSC was associated with superior results,although the outcomes remain far from the goals set by the WHO.CONCLUSION With the elaboration of the HCV cascade of care using local data,it was possible to stratify and evaluate risk factors associated with losses between each step of the cascade,to inform new strategies to guide elimination efforts in the future.

Epidemiology of hepatitis C virus infection

Globally, hepatitis C virus (HCV) has infected an estimated 130 million people, most of whom are chronically infected. HCV-infected people serve as a reservoir for transmission to others and are at risk for developing chronic liver disease, cirrhosis, and primary hepatocellular carcinoma (HCC). It has been estimated that HCV accounts for 27% of cirrhosis and 25% of HCC worldwide. HCV infection has likely been endemic in many populations for centuries. However, the wave of increased HCV-related morbidity and mortality that we are now facing is the result of an unprecedented increase in the spread of HCV during the 20th century. Two 20th century events appear to be responsible for this increase; the widespread availability of injectable therapies and the illicit use of injectable drugs.

Hepatitis B virus and hepatitis C virus dual infection

Hepatitis B virus(HBV)and hepatitis C virus(HCV)share common mode of transmission and both are able to induce a chronic infection.Dual HBV/HCV chronic coinfection is a fairly frequent occurrence,especially in high endemic areas and among individuals at high risk of parenterally transmitted infections.The intracellular interplay between HBV and HCV has not yet been sufficiently clarified,also due to the lack of a proper in vitro cellular model.Longitudinal evaluation of serum HBV DNA and HCV RNA amounts has revealed that complex virological profiles may be present in coinfected patients.Dual HBV/HCV infection has been associated to a severe course of the liver disease and to a high risk of developing hepatocellular carcinoma.Despite the clinical importance,solid evidence and clear guidelines for treatment of this special population are still lacking.This review summarizes the available data on the virological and clinical features as well as the therapeutic options of the dual HBV/HCV infection,and highlights the aspects that need to be better clarified.

Hepatitis C virus in the new era:Perspectives in epidemiology,prevention,diagnostics and predictors of response to therapy

Despite the great successes achieved in the fields of virology and diagnostics,several difficulties affect improvements in hepatitis C virus(HCV)infection control and eradication in the new era.New HCV infections still occur,especially in some of the poorest regions of the world,where HCV is endemic and long-term sequelae have a growing economic and health burden.An HCV vaccine is still no available,despite years of researches and discoveries about the natural history of infection and host-virus interactions:several HCV vaccine candidates have been developed in the last years,targeting different HCV antigens or using alternative delivery systems,but viral variability and adaption ability constitute major challenges for vaccine development.Many new antiviral drugs for HCV therapy are in preclinical or early clinical development,but different limitations affect treatment validity.Treatment predictors are important tools,as they provide some guidance for the management of therapy in patients with chronic HCV infection:in particular,the role of host genomics in HCV infection outcomes in the new era of direct-acting antivirals may evolve for new therapeutic targets,representing a chance for modulated and personalized treatment management,when also very potent therapies will be available.In the present review we discuss the most recent data about HCV epidemiology,the new perspectives for the prevention of HCV infection and the most recent evidence regarding HCV diagnosis,therapy and predictors of response to it.

Postoperative adjuvant antiviral therapy for hepatitis B/C virus-related hepatocellular carcinoma:A meta-analysis

AIM:To investigate the impact of postoperative antiviral treatment on tumor recurrence and survival of patients with chronic hepatitis B virus(HBV) or hepatitis C virus(HCV) infection-related primary hepatocellular carcinoma(HCC) after curative therapy.METHODS:We performed a meta-analysis of randomized and non-randomized control trials from electronic search and manual search.The fixed effect model of Mantel-Haenszel method and the random effect model of Der Simonian and Laird method were used for homogeneous and heterogeneous studies,respectively.Seven HCV-related studies,three HBV-related studies and three studies on HBV or HCV-related HCC were identified.RESULTS:A total of 1224 patients were included in this analysis.The estimated odds ratios(OR) for the 1-,2-,3-and 5-year recurrence were 0.54 [15.4% vs 24.1%,95% confidence interval(CI):0.32-0.89,P=0.02],0.42(36.9% vs 58.0%,95% CI:0.19-0.90,P=0.03),0.37(47.9% vs 63.8%,95% CI:0.19-0.71,P=0.003),and 0.32(66.7% vs 74.3%,95% CI:0.15-0.66,P=0.002),respectively;and the OR for the 1-,2-,3-,5-and 7-year mortality were 0.23(1.2% vs 9.1%,95% CI:0.07-0.71,P=0.01),0.31(6.4% vs 22.1%,95% CI:0.12-0.79,P=0.01),0.43(12.7% vs 20.8%,95% CI:0.21-0.89,P=0.02),0.42(25.1% vs 42.0%,95% CI:0.27-0.66,P=0.0002) and 0.28(31.9% vs 52.2%,95% CI:0.13-0.59,P=0.0008).CONCLUSION:This meta-analysis indicates the postoperative antiviral therapy,interferon in particular,may serve as a favorable alternative to reduce recurrence and mortality in patients with HBV/HCV related HCCs.

Peginterferon and ribavirin treatment for hepatitis C virus infection

Pegylated interferon α (IFNα) in combination with ribavirin is currently recommended as a standard-of-care treatment for chronic hepatitis C virus (HCV) infection. This combination therapy has drastically improved the rate of sustained virological response, specifically in difficult-to-treat patients. Recently, individualized treatment, such as response-guided therapy, is being developed based on host-, HCV- and treatment-related factors. Furthermore, modified regimens with currently available medications, novel modified IFNα and ribavirin or combinations with specifically targeted antiviral therapy for HCV agents, are currently being investigated. The purpose of this review is to address some issues and epoch-making topics in the treatment of chronic HCV infection, and to discuss more optimal and highly individualized therapeutic strategies for HCV-infected patients.

Global elimination of hepatitis C virus infection:Progresses and the remaining challenges

Today, with the introduction of interferon-free direct-acting antivirals and outstanding progresses in the prevention, diagnosis and treatment of hepatitis C virus(HCV) infection, the elimination of HCV infection seems more achievable. A further challenge is continued transmission of HCV infection in high-risk population specially injecting drug users(IDUs) as the major reservoir of HCV infection. Considering the fact that most of these infections remain undiagnosed, unidentified HCVinfected IDUs are potential sources for the rapid spread of HCV in the community. The continuous increase in the number of IDUs along with the rising prevalence of HCV infection among young IDUs is harbinger of a forthcoming public health dilemma, presenting a serious challenge to control transmission of HCV infection. Even the changes in HCV genotype distribution attributed to injecting drug use confirm this issue. These circumstances create a strong demand for timely diagnosis and proper treatment of HCV-infected patients through risk-based screening to mitigate the risk of HCV transmission in the IDUs community and, consequently, in the society. Meanwhile, raising general awareness of HCV infection, diagnosis and treatment through public education should be the core activity of any harm reduction intervention, as the root cause of failure in control of HCV infection has been lack of awareness among young drug takers. In addition, effective prevention, comprehensive screening programs with a specific focus on high-risk population, accessibility to the new anti-HCV treatment regimens and public education should be considered as the top priorities of any health policy decision to eliminate HCV infection.

Prevalence of type 2 diabetes in Algerian patients with hepatitis C virus infection

AIM:To investigate the prevalence of,and risk factors for,diabetes mellitus(DM) in Algerian patients with chronic hepatitis C virus(HCV) infection and in a control group.METHODS:A cross-sectional study was undertaken.A total of 416 consecutive patients with viral chronic hepatitis attending the Internal Medicine Department of the University Hospital Center Touhami Benflis in Batna [290 HCV-infected and 126 hepatitis B virus(HBV)-infected patients] were prospectively recruited.RESULTS:The prevalence of DM was higher in HCV-infected patients in comparison with HBV-infected patients(39.1% vs 5%,P < 0.0001).Among patients without cirrhosis,diabetes was more prevalent in HCV-infected patients than in HBV-infected patients(33.5% vs 4.3%,P < 0.0001).Among patients with cirrhosis,diabetes was more prevalent in HCV-infected patients,but the difference was not significant(67.4% vs 20%,P = 0.058).The logistic regression analysis showed that HCV infection [odds ratio(OR) 4.73,95% CI:1.7-13.2],metabolic syndrome(OR 12.35,95% CI:6.18-24.67),family history of diabetes(OR 3.2,95% CI:1.67-6.13) and increased hepatic enzymes(OR 2.22,95% CI:1.1-4.5) were independently related to DM in these patients.CONCLUSION:The high prevalence of diabetes in HCV-infected patients,and its occurrence at early stages of hepatic disease,suggest that screening for glucose abnormalities should be indicated in these patients.

Useful biomarkers for assessment of hepatitis C virus infection-associated autoimmune disorders

During the course of chronic hepatitis C virus(HCV)infection,various extrahepatic manifestations of autoimmune disorders may occur,including arthralgia/arthritis,sicca complex,purpura,cutaneous ulcer,and thyroid dysfunction.In addition,the prevalence of circulating autoantibodies is high among patients with HCV infection.Commonly detected autoantibodies in HCVinfected patients include rheumatoid factor,antinuclear antibody,anti-SSA/anti-SSB antibody,cryoglobulin,antineutrophil cytoplasmic antibody,anti-smooth muscle antibody,anti-liver and anti-thyroid autoantibodies.These autoantibodies may be associated with underlying autoimmune disorders or liver inflammation in HCV infection.A possible reason for antibody production is overactivation and proliferation of B lymphocytes,via the interaction with the surface protein of HCV.Because immunotherapy can cause HCV flare-up or liver damage,overdiagnosis of HCV-related autoimmune symptoms as primary autoimmune disorders should be avoided.This review describes biomarkers that are useful in clinically evaluating autoimmune manifestations and disorders associated with HCV infection.

Hepatitis C virus in Pakistan:A systematic review of prevalence,genotypes and risk factors

In Pakistan more than 10 million people are living with Hepatitis C virus (HCV), with high morbidity and mortality. This article reviews the prevalence, genotypes and factors associated with HCV infection in the Pakistani population. A literature search was performed by using the keywords; HCV prevalence, genotypes and risk factors in a Pakistani population, in Pubmed, PakMediNet and Google scholar. Ninetyone different studies dating from 1994 to May 2009 were included in this study, and weighted mean and standard error of each population group was calculated. Percentage prevalence of HCV was 4.95% ± 0.53% in the general adult population, 1.72% ± 0.24% in the pediatric population and 3.64% ± 0.31% in a young population applying for recruitment, whereas a very high 57% ± 17.7% prevalence was observed in injecting drug users and 48.67% ± 1.75% in a multi-transfused population. Most prevalent genotype of HCV was 3a. HCV prevalence was moderate in the general population but very high in injecting drug users and multi-transfused populations. This data suggests that the major contributing factors towards increased HCV prevalence include unchecked blood transfusions and reuse of injection syringes. Awareness programs are required to decrease the future burden of HCV in the Pakistani population.
