Abstract
BACKGROUND AND AIMS Predictors of chronic HCV response to oral antiviral therapy (OAT) are related to host genetic variations. Single nucleotide polymorphisms (SNP) and alleles variations of host genes in association with hepatic fibro-cirrhotic changes have a distinct role in OAT outcomes. The current research evaluated the association of Cirrhosis-Risk-Scores (CRS) values, based on the correlation of seven genes signature-SNPs, with sonographic liver parenchymal changes in determining OAT outcomes. METHODS All study subjects (n = 54) were recruited three months after completing OAT and classified into three groups. Group I (n = 21) had negative HCV PCR, group II (n = 17) showed positive solitary intra-PBMCs HCV infection, and group III(n = 16) was serum HCV RNA PCR-positive. All study-population were subjected to examination by hepatic-ultrasound (US), FIB-4-scoring, and screening for 7 gene-signature that addressed CRS values as low, intermediate, and high depending on gene SNPs identification. RESULTS Group I showed a significant association with low CRS values compared to other groups (P < 0.001). Solitary intra- PBMCs HCV infection in group II was significantly combined with intermediate CRS values in comparison to groups I and III (P < 0.001). The high CRS values were significantly found in group III when compared to groups I and II (P < 0.01). On US imaging, low CRS values were common in normally appeared hepatic parenchyma (P < 0.001) and high CRS values were frequent in coarse-liver (P < 0.001), while bright-liver-tissues appearance was mainly detected in the intermediate CRS category (P = 0.09). On FIB-4 scoring, high CRS value were associated with hepatic fibro-cirrhosis compared to intermediate (P < 0.001) and low (P = 0.08) CRS-categories. CONCLUSION The current study concluded the association of (a) high CRS values with coarse liver in viral-RNA serologic relapse, (b) low CRS values with normal liver tissues in sustained virologic response (SVR), (c) intermediate CRS values with bright liver in solitary PBMCs relapse.

Abstract
Hepatitis C virus (HCV) is a major public health problem that affects more than 170 million people globally. HCV is a principal cause of hepatocellular carcinoma (HCC) around the globe due to the high frequency of hepatitis C infection, and the high rate of HCC is seen in patients with HCV cirrhosis. TP53 is considered as a frequently altered gene in all cancer types, and it carries an interferon response element in its promoter region. In addition to that, the TP53 gene also interacts with different HCV proteins. HCV proteins especially NS3 protein and core protein induce the mutations in the TP53 gene that lower the expression of this gene in HCV patients and leads to HCC development. In this study, we examined the transcriptional analysis of the TP53 gene in HCV-infected patients administered with different combinations of antiviral therapies including sofosbuvir + daclatasvir, sofosbuvir + ribavirin, and pegylated interferon + ribavirin. This study included 107 subjects; 15 treated with sofosbuvir + daclatasvir, 58 treated with sofosbuvir + ribavirin, 11 treated with interferon + ribavirin, 8 untreated, 10 HCC patients, and 5 were healthy controls. Total RNA was extracted from the PMBCs of HCV infected patients and reverse transcribed into cDNA using a gene specific reverse primer. The expression level of TP53 mRNA was analyzed using quantitative PCR. The expression of TP53 mRNA was notably upregulated in rapid virological response (RVR), early virological response (EVR), and sustained virological response (SVR) groups as compared to non-responders and naïve groups. The expression of TP53 mRNA was seen high in HCC as compared to control groups. Additionally, it has been demonstrated that sofosbuvir + daclatasvir treatment stimulates significant elevation in TP53 gene expression as compared to (sofosbuvir + ribavirin) and (IFN + ribavirin) treatment. This study indicates that the TP53 gene expression is highly upregulated in RVR, EVR, and SVR groups as compared to control groups. Moreover, sofosbuvir + daclatasvir therapy induces significant rise in TP53 mRNA expression levels as compared to (sofosbuvir + ribavirin) and (IFN + ribavirin) treatment. According to these results, it can be concluded that sofosbuvir + daclatasvir plays a significant role in preventing HCV patients from developing severe liver complications as compared to other administered therapies. This study is novel as no such type of study has been conducted previously on the expression of TP53 in local HCV-infected population treated with different combinations of therapies. This study is helpful for the development of new therapeutic strategies and for improving existing therapies.

Abstract
Haemophilia is a rare, hereditary bleeding disorder. Clotting factor concentrates were a revolutionary treatment which changed the life of people with haemophilia. However, early generation of clotting factor concentrates, without viral inactivation procedures in the manufacturing process, led to an increased risk of transmission of blood-borne viral infections, mainly due to hepatitis C virus and human immunodeficiency virus. As only 20% of HCV-infected patients clear the infection naturally, chronic HCV infection constitutes a serious health problem and a major cause of chronic liver disease in this group of patients. Fortunately, the use of viral inactivation procedures in the plasma-derived factor concentrates manufacturing process and the availability of alternative treatment options, led to a significant reduction of transfusion-associated viral infections. The advent of multiple, orally administrated, highly effective direct-acting antivirals (DAAs) is changing the natural history of HCV infection in patients with haemophilia as these drugs have an excellent safety profile and achieve very high sustained virological response rates, similar to the general population. Eradication of HCV-infection in patients with haemophilia is feasible via micro-elimination projects.

Abstract
Abstract
Background
Patients with chronic hemolytic anemias (CHA) are at a high risk for transfusion-transmitted infections. Various studies in Egypt have shown a prevalence of hepatitis C virus (HCV) infection in 24–37% of those patients. Elimination of hepatitis C virus (HCV) in patients with CHA would prevent early progression of liver disease. In this study, we aimed to assess the efficacy, safety, and tolerability of sofosbuvir (SOF) and daclatasvir (DAC) in the special population of HCV-infected patients with CHA. In this prospective study, 21 consenting hepatitis C patients were recruited and treated using ribavirin-free SOF/DAC regimen for either 12 or 24 weeks according to categorization of patients into easy or hard-to-treat in accordance with the national protocols. Sustained virological response was assessed by RT-PCR for HCV-RNA at 12 weeks post-treatment (SVR12). Any treatment-related adverse events were noted.
Results
All patients were adherent to treatment with no discontinuation of therapy. SVR12 was achieved in 19 out of 21 patients (90.5%). There was a significant improvement in levels of ALT (p<0.009) after completion of therapy. On the other hand, the hemoglobin, total bilirubin, and ferritin levels showed a non-significant difference (p<0.501, p<0.542, and p<0.339, respectively). Moderate adverse events were observed in 2 out of 21 patients (9.5%), including sickling crisis and hepatic decompensation.
Conclusion
The results of this study substantiate the favorable efficacy, safety, and tolerability of ribavirin-free direct-acting antivirals (DAAs) in the special population of HCV-infected patients with CHA. Micro-elimination of HCV in special patient populations allows for pragmatic delivery of care to patients with co-morbid conditions who are in most need for treatment and allows for achievement of global elimination of HCV worldwide.

Abstract
Abstract
Background
Hepatitis C virus (HCV) infection is a major cause of liver-related morbidity and mortality among thalassemic patients. Direct-acting antiviral agents (DAAs) are highly effective and well-tolerated by chronic HCV patients.
Results
The mean age of our patients was 29 years. Sustained virologic response (SVR) at 12 and 24 weeks was achieved in all patients (100%). The most common side effects were fatigue (18%), anemia (13.63%), and headache (4.5%). There was no statistically significant difference in the hemoglobin level before and after treatment (p = 0.48). There was a significant improvement in serum bilirubin and mean ALT levels after treatment compared to baseline data (p < 0.0005 each).
Conclusions
DAAs, namely, sofosbuvir plus daclatasvir or sofosbuvir plus ledipasvir, are effective and well-tolerated regimens in thalassemic patients with chronic HCV.

Abstract
BACKGROUND This 5-year follow-up of the CCgenos cross-sectional study aimed to observe real-life outcomes in a cohort of 997 Han Chinese patients with chronic HCV infection and to explore the impacts of HCV genotype, patient characteristics and treatment status. METHODS Clinical information and centralized HCV RNA measures were collected every 6/3 months for untreated/treated patients. Overall disease progression was defined as ≥1 of: de novo development of cirrhosis, Child-Turcotte-Pugh score increased by ≥2 points (if cirrhosis at baseline), progression to decompensated cirrhosis, hepatocellular carcinoma (HCC), liver transplant or death. Cox regression assessed risk factors for the time from estimated infection to cirrhosis or HCC. Logistic regression assessed risk factors for incidence rates of cirrhosis and overall disease progression. RESULTS 281 of 514 patients enrolled across China completed 5 years of follow-up. Overall disease progression occurred in 36/364 (9.9%) treated patients and 35/148 (23.6%) untreated patients (odds ratio = 0.35; 95% CI 0.21, 0.59; P<0.0001). Overall disease progression occurred in 6/231 (2.6%) patients achieving sustained virological response at 24 weeks (SVR24) versus 11/82 (13.4%) who did not (P=0.0002). Cirrhosis development was significantly associated with abnormal aspartate aminotransferase (AST), age ≥40 years, body mass index ≥28 kg/m2, HCV GT1, platelet count <100×109/l, and AST to platelet ratio index (APRI) ≥2 (multivariate Cox regression, P<0.05). HCC was significantly associated with HCV GT1 and platelet count <100×109/l (multivariate Cox regression, P<0.05). CONCLUSIONS Achieving SVR24 significantly reduced the probability of overall disease progression but no significant difference was seen for both cirrhosis and HCC during 5 years of follow-up.

Abstract
In 1989, a collaboration between the Centers for Disease Control (CDC) and a California biotechnology company identified the hepatitis C virus (HCV, formerly known as non-A, non-B hepatitis virus) as the causative agent in the epidemic of silent posttransfusion hepatitis resulting in cirrhosis. We now know that, the HCV genome is a 9.6 kb positive, single-stranded RNA. A single open reading frame encodes a 3011 amino acid residue polyprotein that undergoes proteolysis to yield 10 individual gene products, consisting of 3 structural proteins (core and envelope glycoproteins E1 and E2) and 7 nonstructural (NS) proteins (p7, NS2, NS3, NS4A, NS4B, NS5A, and NS5B), which participate in posttranslational proteolytic processing and replication of HCV genetic material. Less than 25 years later, a new class of medications, known as direct-acting antivirals (DAAs) which target these proteins, were introduced to treat HCV infection. These highly effective antiviral agents are now approved for use in children as young as 3 years of age and have demonstrated sustained virologic responses exceeding 90% in most genotypes. Although tremendous scientific progress has been made, the incidence of acute HCV infections has increased by 4-fold since 2005, compounded in the last decade by a surge in opioid and intravenous drug use. Unfortunately, awareness of this deadly hepatotropic virus among members of the lay public remains limited. Patient education, advocacy, and counseling must, therefore, complement the availability of curative treatments against HCV infection if this virus is to be eradicated.

Abstract
Liver fibrosis is one of the risk factors for hepatocellular carcinoma (HCC) development. The staging of liver fibrosis can be evaluated only via a liver biopsy, which is an invasive procedure. Noninvasive methods for the diagnosis of liver fibrosis can be divided into morphological tests such as elastography and serum biochemical tests. Transient elastography is reported to have excellent performance in the diagnosis of liver fibrosis and has been accepted as a useful tool for the prediction of HCC development and other clinical outcomes. Two-dimensional shear wave elastography is a new technique and provides a real-time stiffness image. Serum fibrosis markers have been studied based on the mechanism of fibrogenesis and fibrolysis. In the healthy liver, homeostasis of the extracellular matrix is maintained directly by enzymes called matrix metalloproteinases (MMPs) and their specific inhibitors, tissue inhibitors of metalloproteinases (TIMPs). MMPs and TIMPs could be useful serum biomarkers for liver fibrosis and promising candidates for the treatment of liver fibrosis. Further studies are required to establish liver fibrosis-specific markers based on further clinical and molecular research. In this review, we summarize noninvasive fibrosis tests and molecular mechanism of liver fibrosis in current daily clinical practice.

Abstract
The hepatitis C virus (HCV) infects 71.1 million persons and causes 400,000 deaths annually worldwide. HCV mostly infects the liver, causing acute and chronic necroinflammatory damage, which may progress toward cirrhosis and hepatocellular carcinoma. In addition, HCV has been associated with several extrahepatic manifestations. The advent of safe and effective direct-acting antivirals (DAAs) has made the dream of eliminating this public health scourge feasible in the medium term. Prospective studies using DAA-based regimens have shown the benefit of HCV clearance in terms of both liver- and non-liver-related mortality.

Abstract
Background/Aim The incidence of hepatocellular carcinoma (HCC) in patients with transfusion dependent thalassemia (TDT) has been increasing, where viral hepatitis and iron overload are the two established HCC risk factors. The aim of this study was to investigate the etiological factors of HCC development and to evaluate the possible factors associated with survival in our cohort of TDT patients with HCC. Methods Records of patients with TDT diagnosed with HCC from 2008 to 2018 were reviewed. Liver iron concentration (LIC) has been assessed by the signal-intensity-ratio MRI. The diagnosis of HCC was made by a 3-phase contrast magnetic resonance imaging (MRI) and patients were staged and treated for HCC according to Barcelona Clinic Liver Cancer (BCLC) grading system. Results Forty-two TDT patients with HCC have been included. Most of them (78.5%) were anti-HCV positive, 59.5% HCV-RNA positive, and 16.5% had serological markers of resolved HBV infection. Patients with HCV infection have been treated successfully with either Peg-IFNa±Ribavirin or with the new direct antivirals (DAAs). At the time of HCC diagnosis, all patients with chronic HCV infection were HCV-RNA negative, 78.5% had underlying cirrhosis, and the vast majority (98%) had average or mild elevated LIC values. According to the BCLC system, patients were classified as 0-A: 28.5%, B: 57% and C-D: 14.5%. HCC has been treated with loco-regional treatment in 78.5% of our patients, while the rest have received sorafenib. Twenty-eight patients (66.5%) died due to HCC with a median survival time of 6 months (range: 2-60). Using the Cox proportional hazard model, the only factors associated with poor survival were BCLC stages C and D. Conclusions In conclusion, BCLC staging is the main prognostic factor of survival in patients with TDT who develop HCC.

Abstract
The objective of this project was to describe longitudinal change in chronic hepatitis C virologic reponse using time-to-event (TTE) analysis and to identify patient characteristics that determine the dynamics of this change. We compiled demographic, clinical, and genetic data from 715 chronic hepatitis C virus (HCV) patients treated with pegylated interferon (PEG-IFN) alfa-2a and ribavirin. TTE modelling described the time between antiviral treatment initiation and the first observation of undetectable HCV RNA. A lognormal TTE model was selected to describe time to first undetectable HCV RNA. The identified predictors of prolonged time to achieve undetectable HCV RNA include HCV genotype 1, low pre-treatment ALT level, older age, or with elevated baseline haemoglobin level. In conclusion, a cohort of patients with low probability of achieving SVR can be identified. This project identifies patients with a low risk of responding to PEG-IFN alfa-2a and ribavirin combination.

Abstract
Recognizing the importance of timely guidance regarding the rapidly evolving field of hepatitis C management, the American Association for the Study of Liver Diseases (AASLD) and the Infectious Diseases Society of America (IDSA) developed a web-based process for the expeditious formulation and dissemination of evidence-based recommendations. Launched in 2014, the hepatitis C virus (HCV) guidance website undergoes periodic updates as necessitated by availability of new therapeutic agents and/or research data. A major update was released electronically in September 2017, prompted primarily by approval of new direct-acting antiviral agents and expansion of the guidance's scope. This update summarizes the latest release of the HCV guidance and focuses on new or amended recommendations since the previous September 2015 print publication. The recommendations herein were developed by volunteer hepatology and infectious disease experts representing AASLD and IDSA and have been peer reviewed and approved by each society's governing board.

Abstract
Hepatitis C virus (HCV) is the most common blood-borne infection in the United States and is of concern in older adults. HCV infection is associated with not only hepatic but also extrahepatic comorbidities common to the aging patient including diabetes, kidney and cardiovascular diseases, and neurocognitive impairment. The effect of direct-acting antiviral agents to treat HCV on these outcomes is limited. This article summarizes the literature regarding the epidemiology and natural history of HCV infection; the impact of age on clinical outcomes in HCV-infected persons; and current knowledge regarding safety and efficacy of HCV treatment regimens in the older patient.

Abstract
Hereditary bleeding disorders include a group of diseases with abnormalities of coagulation. Prior to 1990, infection with hepatitis C virus (HCV) was mainly transmitted via pooled plasma products as a treatment for hereditary bleeding disorders. Anti-HCV positivity in these patients may be as high as >70% in some areas, while some of them have also been coinfected with human immunodeficiency virus. Since about 20% of HCV-infected patients clear the infection naturally, chronic HCV infection represents a significant health problem in this group of patients. Mortality due to chronic HCV infection is estimated to be >10 times higher in patients with hemophilia than in the general population, and is mainly due to liver cirrhosis and hepatocellular carcinoma. The antiviral treatment of HCV in patients with hereditary bleeding disorders is not different from that of any other infected patients. Nevertheless, many patients with hereditary bleeding disorders have declined (Peg)interferon-based treatment because of side effects. In recent years, multiple orally administrated direct-acting antivirals (DAAs) have been approved for HCV treatment. Unfortunately, there is not much experience from treating these patients with DAA regimens, as major studies and real-life data did not include adequate numbers of patients with inherited hemorrhagic disorders. However, the available data indicate that DAAs have an excellent safety profile with a sustained virological response rate of >90%.

Abstract
INTRODUCTION The seroprevalence of hepatitis C virus (HCV) infection tends to be higher in the elderly than in younger populations. Meanwhile, age per sec is an unfavorable determinant that has an impact on liver-related outcomes. Geriatric chronic hepatitis C (CHC) patients would be viewed as a special population and have an urgent need for viral eradication. Areas covered: The antivirals for CHC have evolved from interferon (IFN)-based therapyto interferon-free DAAs. The treatment strategy, in terms of its clinical efficacy and drug safety, in the elderly is presented. Expert opinion: In the previous IFN era, the sustained virological response (SVR) rate of the elderly was lower. More unfavorable safety concerns attributing to the underlying liver disease severity and extra-hepatic presentations further compromised the treatment efficacy. In the IFN-free DAA era, data showing similar SVR rates and safety profiles between the elderly and their counterparts have been demonstrated. Notably, aging is an unfavorable factor for fibrosis regression and HCC development even after HCV eradication. The extent of the improvement of extra-hepatic manifestations in the elderly with SVR is also unclear. The long-term benefits of viral eradication by DAAs in the elderly await further explorations.

Abstract
Hepatitis is defined as inflammation of the liver. This inflammation can be acute and self-limited, chronic (leading to cirrhosis and an increased risk for hepatocellular carcinoma), or fulminant (requiring lifesaving liver transplantation). Although there are many causes of hepatitis, this article focuses on the main childhood viral hepatidities: types A, B, C, D, and E. This review discusses the main characteristics of each virus, including salient epidemiology, clinical characteristics, diagnosis, treatment, and prevention strategies.

Abstract
The incidence of hepatocellular carcinoma (HCC) in patients with thalassemia is on the rise. The 2 well recognized HCC risk factors in thalassemia are iron overload and chronic viral infection with hepatitis C. The carcinogenicity of iron is related to its induction of oxidative damage, which results in genotoxicity, and to immunologic dysregulation, which attenuates cancer immune surveillance. Chronic hepatitis B and C infections lead to necroinflammation, which can prompt progression to HCC, but an independent role of hepatitis B virus in hepatic carcinogenesis among patients with thalassemia has not been demonstrated. Screening patients who have thalassemia using magnetic resonance imaging-based liver iron concentration measurement and liver ultrasound is recommended for early detection of iron overload and HCC, respectively. Prevention primarily resides in hepatitis B vaccination, donor blood screening, hepatitis treatment, and iron chelation. Although solid data is lacking on the outcomes of HCC treatment in patients with thalassemia, a personalized approach tailored to the individual patient's comorbidities remains necessary for treatment success. Treatment modalities for HCC include surgical resection, chemoembolization, and liver transplantation, among others. Multicenter studies are needed to better explore therapeutic targets that can improve the prognosis of these patients. Cancer 2017;123:751-58. © 2016 American Cancer Society.

Abstract
BACKGROUND Fibrosis progression varies markedly in hepatitis C virus (HCV)-infected individuals. We investigated factors that influence fibrosis progression in chronic HCV infection. METHODS HCV-infected patients who underwent at least 2 liver biopsies were included in this study. Associations between fibrosis progression and epidemiologic, virologic, and disease-associated factors were analyzed using logistic regression and multistate Markov modeling. RESULTS We analyzed 936 biopsy specimens obtained from 378 individuals. Mean age (±SD) at first biopsy was 48.3 ± 9.3 years, 59.3% of patients were male, 59.9% were white, and 86.7% were infected with HCV genotype 1. Fibrosis progression and cirrhosis occurred in 57.4% and 5.8%, respectively. Fibrosis progression between the first and last biopsies was associated with lower fibrosis in the first biopsy specimen (P < .001) and with the occurrence of at least 1 flare in the alanine aminotransferase (ALT) level (>200 U/L; P = .007). We found the highest fibrosis progression rate between stages 0 and 1 and the lowest between stages 2 and 3. Increased necroinflammation and higher ALT level were associated with faster progression. HCV genotype 3-infected patients were more likely to progress to cirrhosis (P < .001). CONCLUSIONS Fibrosis progression in HCV is not linear but varies according to stage, with the highest progression in patients with the lowest fibrosis severity. Patients who experience flares in the ALT level are also more likely to progress.

Abstract
The majority of patients with hepatitis C virus (HCV) in China were infected via blood transfusion prior to the year 1996. In this systematic retrospective cohort study, disease progression in 804 consecutive patients with transfusion-acquired HCV is investigated. In addition, the occurrence of compensated cirrhosis, decompensated cirrhosis and hepatocellular carcinoma (HCC) is analyzed among these patients, along with the risk factors for disease progression. Patients with cirrhosis or HCC were classified as the serious development group (SD group) and the remaining patients with chronic hepatitis were classified as the hepatitis group (H group). Significant differences were found between the two groups in age at the time of infection, duration of infection and age at the time of observation. SD group patients were significantly older at the time of transfusion (33.73 vs. 23.56 years; P<0.001), with a significantly longer mean duration of HCV infection (21.88 vs. 21.15 years; P=0.029) compared with that in the H group. Male gender and age at the time of transfusion were significant risk factors for HCC (OR=2.48, P=0.031 and OR=1.07, P=0.002, respectively). Age was a significant risk factor for disease progression in older Chinese patients with transfusion-acquired HCV, and there were significant differences in the prevalence of compensated cirrhosis, decompensated cirrhosis and HCC between the age groups (P<0.001), suggesting that more patients with HCV may develop cirrhosis or HCC in their third and fourth decades of infection. Results of the present study will be helpful for predicting disease progression in Chinese patients with HCV infected via blood transfusion.

Abstract
The hepatic damage caused by hepatitis C virus (HCV) infection is associated with the host immune response and viral regulatory factors. Catalase (CAT) and glutathione peroxidase 1 (GPX1) are antioxidant enzymes located in the peroxisomes and mitochondria, respectively, and are responsible for the control of intracellular hydrogen peroxide levels. Polymorphisms in CAT (C-262T) and GPX1 (Pro198Leu) are correlated with serum levels and enzyme activity. This study aimed to investigate the association of genetic polymorphisms of CAT C-262T (rs1001179) and GPX1 Pro198Leu (rs1050450) with different stages of liver fibrosis and development of hepatocellular carcinoma (HCC). This study included 445 patients with chronic hepatitis C, of whom 139 patients had mild fibrosis (F0-F1), 200 had moderate/severe fibrosis (F2-F4), and 106 had HCC. Genotyping of SNPs was performed by real-time PCR using TaqMan probes. The Pro/Pro genotype of GPX1 was significantly associated with fibrosis severity, HCC, Child Pugh score, and BCLC staging. Additionally, patients carrying both CT+TT genotypes in the CAT gene and the Pro/Pro genotype in the GPX1 gene had higher risk for developing moderate/severe fibrosis or HCC (p = 0.009, OR 2.40 and p = 0.002, OR 3.56, respectively). CAT and GPX1 polymorphisms may be implicated in the severity of liver fibrosis and HCC caused by HCV.

Abstract
Background and Objectives Hepatitis C virus (HCV) is a major health problem in Egypt with its prevalence estimated to be 14.7% among the general population in 2008. Patients receiving frequent blood transfusions like those with sickle cell disease (SCD) are more exposed to the risk of acquiring HCV. IL28B gene polymorphisms have been associated with spontaneous HCV clearance. This study aims to determine the prevalence of HCV infection among children with SCD and to investigate the relation between IL28B gene polymorphisms and spontaneous HCV clearance. Methods Seventy SCD patients were screened for HCV antibody. HCV-positive patients were tested for the level of HCV RNA using quantitative real-time PCR. IL28B polymorphisms (rs 12979860 SNP and rs 12980275 SNP) were detected using TaqMan QRT-PCR and sequence-specific primers PCR respectively. Results Sixteen patients (23%) were HCV antibody positive, 9 of them (56.3%) had undetectable HCV RNA in serum, and 7 (43.7%) had persistent viremia. Genotypes CC/CT/TT of rs12979860 were found in 30 (42.9%), 29 (41.4%) and 11 (15.7%) patients and rs12980275 AA/AG/GG were found in 8 (11.4%), 59 (84.3%) and 3 (4.3%) patients. There was no significant difference in the frequency of IL28B (rs 12979860 and rs12980275) genotypes among HCV patients who cleared the virus and those with persistent viremia (p=0.308 and 0.724 respectively). Conclusion Egyptian SCD patients have a high prevalence of HCV. Multi-transfused patients still exposed to the risk of transmission of HCV. IL28B gene polymorphismsare not associated with spontaneous clearance of HCV in this cohort of Egyptian children with SCD.

Abstract
Hepatitis C virus (HCV) genotype (GT) 4 represents 12%-15% (15-18 million) of total global HCV infection. It is prevalent in Northern and Equatorial Africa and the Middle East, and is also present in some countries in Europe. GT-4 (and subtype 4a in particular) dominates the HCV epidemic in Egypt. In underdeveloped countries, risk factors associated with HCV infection may be due to unsafe medical practices or other factors such as familial transmission, mother’s HCV status, or illiteracy. HCV prevention and control programs should include health education, increased community awareness towards the disease, controlling infection distribution in health-care centers, proper sterilization of medical and dental instruments, and ensuring safe supply of blood and blood-products. Response rates to a 48-wk combined pegylated-interferon (PEG-IFN) and ribavirin (RBV) treatment range from 40%-69%, and HCV-GT-4 has been considered better than GT-1 but worse than GT-2 and GT-3 in treatment with PEG-IFN/RBV. However, with the introduction of the HCV-GT-1 effective protease inhibitors boceprevir and telaprevir in 2011, HCV-GT-4 became the “most difficult (GT) to treat”. Recently, the direct-acting antivirals (DAAs) with pan- genotypic activities simeprevir, sofosbuvir, and daclatasvir have been recommended in triple regimens with PEG-IFN/RBV for the treatment of HCV-GT-4. An IFN-free regimen will be available for treatment of all genotypes of HCV in the near future. To date, several DAAs have been developed and are currently being evaluated in various combinations in clinical trials. As new regimens and new agents are being approved by the Food and Drug Administration, we can expect the guidelines for HCV treatment to be changed. The availability of shorter, simpler, and more tolerable treatment regimens can reduce the morbidity and mortality associated with HCV infection. With such a large number of therapeutic agents available, we can end up with a range of choices that we can select from to treat patients.

Abstract
Hepatitis C infection is a common cause of cirrhosis and indication for liver transplantation in the United States. The incidence of chronic hepatitis C has been declining, but rates of cirrhosis and hepatocellular carcinoma are projected to increase. The outcome of chronic hepatitis C is variable. It is estimated that 20% to 25% will develop cirrhosis over a 25-year to 30-year period. The rate of disease progression is influenced by many host, viral, and environmental factors. Few can be modified.

Abstract
Hepatitis C infection is a global health problem. Most infected children have not been identified. Perinatal transmission is the most common mode of acquisition. Liver disease owing to chronic hepatitis C virus (HCV) infection progresses slowly in individuals infected early in life. Serious complications rarely affect patients during childhood. Successful treatment of HCV in adults has improved and recommendations have changed. Treatment in children should be deferred until direct-acting antivirals and interferon-free regimens are available to this population. If treatment cannot be deferred, regimens including peginterferon and ribavirin can be given to children with compensated liver disease.

Abstract
Hepatocellular carcinoma (HCC) is the third most frequent oncological cause of death worldwide, principally a consequence of hepatitis C virus (HCV) infection and its prognosis is mostly poor. For early identification and surveillance of HCV patients with liver disease progression, the availability of suitable diagnostic and prognostic biomarkers is still an unmet clinical need. Alfa-fetoprotein together with imaging techniques is commonly used, however its specificity and sensitivity are not satisfactory. Several clinical and serological data have been proposed to define the risk of disease progression in HCV infected patients and new biomarkers have been proposed, including post-transcriptionally modified molecules and genetic biomarkers. The present editorial article attempts to summarize the current knowledge on the new promising tools for effective early diagnosis of HCV-related liver disease progression and for the surveillance of HCC.

Abstract
Hepatitis C virus (HCV) infection in the elderly population is a global medical burden and healthcare utilization concern. The majority of patients with hepatitis C in the USA are "baby boomers," who were born between 1945 and 1965. Consistently worldwide, HCV infection in elderly population is overrepresented and poses public health concerns. These individuals have been infected now for over two decades and are presenting with advanced liver disease. Traditionally, the use of pegylated interferon-based therapy has been limited in the elderly because of its adverse effects. The sustained virologic responses have also tended to be lower in the elderly than in younger adults. The emergence of non-interferon-based therapy with direct acting antiviral agents has expanded the pool of patients eligible for treatment. These agents have been found to be effective, tolerable, and safe in the elderly population.

Abstract
OBJECTIVES We sought to assess the characteristics of hepatitis C virus-positive young adults who received a liver transplant and to evaluate posttransplant outcomes. MATERIALS AND METHODS United Network for Organ Sharing database was conducted from 1989 to 2012, and retrospective analysis was performed on all hepatitis C virus-positive young adult patients (aged, 8-35 y) who underwent a liver transplant in the United States. RESULTS A total of 506 hepatitis C virus subjects were included. Average age at time of transplant was 30.1 ± 4.8 years. Median follow-up after first liver transplant was 46.1 months (13, 89.3 mo). During this time, 217 patients (42.8%) died at a mean age at the time of death of 34 ± 6.7 years including 176/ 506 (34.8%) after the first liver transplant, 34/71 (48.6%) after the second liver transplant, and 7/8 (87.5%) after the third liver transplant. The majority (65.7%) of retransplants were performed for hepatitis C virus recurrence. A mean of 1.15 liver transplants were performed per patient. Overall, 262 subjects were transplanted in the pre-Model for End-stage Liver Disease era, and 244 were transplanted post-MELD. Younger age, higher bilirubin, higher creatinine, hepatitis C carcinoma, shorter wait time, shorter cold ischemia time, nonwhite donor race, and the use of mycophenolate mofetil were significantly more common in the post-Model for End-stage Liver Disease era (all with P < .05). Importantly, 5-year patient and graft survival were not different between the pre- and post-Model for End-stage Liver Disease era. CONCLUSIONS Liver transplant in young adults for hepatitis C virus acquired during childhood has poor outcomes that did not improve in the post-Model for End-stage Liver Disease era. These findings should prompt more aggressive evaluation and treatment for hepatitis C virus in children.

Abstract
Background Interleukin 27 (IL-27) has pleiotropic properties that can either limit or enhance immune responses. Recent studies revealed that single nucleotide polymorphisms (SNPs) of the IL-27 promoter region modulate the development of infectious diseases and individual's susceptibility to therapeutic response. Little is known about the relationship between IL-27 single nucleotide polymorphisms and therapy response in patients infected by hepatitis C virus (HCV). In this study we have investigated the potential role of SNPs in the promoter region of IL27 p28 gene (alleles rs153109) on the outcome of HCV infected patients. Methods rs153109, corresponding to position c.-964A>G of the IL-27 locus, was amplified from genomic DNA extracted from 15 patients with chronic hepatitis C stratified by sustained viral response (SVR), relapser and non-responder, after treatment with peginterferon-α (PegIFN- α) combined with ribavirin (RBV). Amplification products were studied by direct sequencing. Results This method has been applied in a preliminary study on patients with chronic hepatitis C to provide information for a standardized assay useful to genotyping of rs153109 SNPs of IL-27p28. The genotype distribution of the c.-964 A>G polymorphism was more present in patients who did not achieve a SVR. By contrast, the genotype G/G was absent in non-responder and relapser patients. Moreover, the analysis of allelic distribution of rs153109 highlighted a predominance of allele A in all genotypes in spite of allele G. Conclusions Our work provides preliminary information for a standardized method potentially useful for genotyping rs153109, and suggests its utility as a candidate approach to evaluate IL-27 p28 polymorphisms as additional clinical predictors of response to therapies in HCV infected patients.

Abstract
AIMS Aim of this study was to assess if host (immunogenetic traits, age, sex), exogenous (alcohol) or viral factors (viral type, past HBV infection) might affect the progression of chronic hepatitis C to liver decompensation or the development of HCC in a cohort of patients exposed to a single blood transfusion prior to the introduction of anti-HCV screening. METHODS Two hundred and forty-eight patients with a history of a single exposure to blood or blood products prior to 1990 were retrospectively considered. Patients were devoid of other risk factors of liver disease or immunosuppression and naïve to antiviral therapies. Eight baseline variables were assessed: age at transfusion, sex, HBV core antibody, immunogenetic profile (DRB1*11, DRB1*1104, DRB1*07), HCV genotype and alcohol consumption. RESULTS The follow-up was 22 (SD: 11) years. Sixty-eight patients (27%) progressed to hepatic decompensation over a median period of 22.5 years (IQR: 14-30) and 41 patients (16%) developed HCC over a median period of 31 years (IQR: 24-38). The cumulative incidence of liver failure was 0.4% (95% CI: 0.1-3.1), 4.9% (95% CI: 2.6-9.3) and 16.2% (95% CI: 10.4-24.7) at 10, 20 and 30 years after blood transfusion respectively. By univariate analysis, only age at transfusion was correlated with the risk of decompensation. Stratifying the age of transfusion by tertiles, the incidence of hepatic decompensation was 0.7% per year in patients transfused at ≤24 years of age as compared to 1.2% and 1.9% per year in those transfused at 25-35 and >36 years of age respectively (HR: 5.5, 95% CI: 2.78-10.7, P<0.001). The risk of HCC development was correlated by univariate analysis with age at transfusion (as continuous variable, HR: 1.12, 95% CI: 1.08-1.16 per year of age, P<0.001, >36 compared to ≤24 years, HR: 10.3, 95% CI: 3.9-26.9, P<0.001) and male sex (HR: 4.2, 95% CI: 1.7-10, P=0.001). Multivariate analysis confirmed age at transfusion and male sex as independent predictors of HCC development [HR: 1.12 per year (95% CI: 1.08-1.16), P<0.001 and HR: 5.4 (95% CI: 2.2-13.2), P<0.001 respectively]. CONCLUSIONS In patients with transfusion-acquired HCV infection, age at transfusion affects the risk for hepatic decompensation. Age at transfusion and male sex are independent risk factors for HCC development.

Abstract
UNLABELLED The natural history of vertically acquired HCV infection is ill defined. The aim of this study was to outline the natural course of vertical HCV infection in a cohort of untreated children, including rate of spontaneous viral clearance, frequency and features of HCV-related autoimmune disorders. Children with vertical HCV infection were prospectively followed from the first month of life with regular clinical and laboratory assessments. Statistical analysis was performed using Prism 5.0. Forty-five children (median age 12 years, interquartile range 6.9-15.5) were studied. Genotype 1 was predominant (53.3 %). Spontaneous viral clearance was achieved by 12 patients (26.7 %) and associated with genotype 3. Alanine-amino-transferase levels were increased in most children in the first 2 years of life with higher values in those who later cleared the infection. All children were asymptomatic for liver disease. Transient elastography (32 patients) showed mild or moderate fibrosis in nine and two cases, respectively. Non-organ-specific autoantibodies were detected in 24 children (53.3 %) independently of viremia; of these, one developed type-1 diabetes. Cryoglobulinemia was associated with genotype 1 infection and found in 15 subjects (33.3 %): two had low C4 levels and persistent proteinuria. CONCLUSIONS Vertically acquired HCV infection may result in spontaneous clearance in up to 27 % of children. Resolution of infection is higher with genotype 3, usually occurs in preschool age and persists over time. Chronic infection is generally asymptomatic, although hepatomegaly and mild fibrosis may develop. Autoantibodies and cryoglobulins are frequent, whereas the associated clinical manifestations are rare.

Abstract
Chronic hepatitis C virus infection affects around 150 million persons, and 350,000 persons worldwide die of this disease each year. Although the data on its natural history are incomplete, after the acute infection, most patients develop chronic forms of hepatitis C with variable stages of fibrosis. In these patients, continual inflammatory activity can cause significant fibrosis, cirrhosis, decompensation of the liver disease, or hepatocarcinoma. In the next few years, it is expected that hepatitis C virus infection and its complications will significantly increase, as will the incidence of hepatocarcinoma in Spain. This review presents the data on the natural history of hepatitis C virus infection and discusses the potential impact of antiviral therapy on the distinct stages of the disease.

Abstract
The portal vein carries blood from the gastrointestinal tract to the liver and in so doing carries microbes as well. The liver may therefore be involved in infections with a myriad number of microbial organisms. While some of these infections most commonly occur in the immunocompromised host, others affect the immune competence. Hepatic infections may be primary in nature or secondary, as part of systemic or contagious disease. The purpose of this chapter is to provide a brief overview of the various infections of the liver in the pediatric patient.

Abstract
Worldwide, an estimated 130-170 million people have HCV infection. HCV prevalence is highest in Egypt at >10% of the general population and China has the most people with HCV (29.8 million). Differences in past HCV incidence and current HCV prevalence, together with the generally protracted nature of HCV disease progression, has led to considerable diversity in the burden of advanced liver disease in different countries. Countries with a high incidence of HCV or peak incidence in the recent past will have further escalations in HCV-related cirrhosis and hepatocellular carcinoma (HCC) over the next two decades. Acute HCV infection is difficult to detect because of the generally asymptomatic nature of the disease and the marginalization of at-risk populations. Around 25% of patients with acute HCV infection undergo spontaneous clearance, with increased rates among those with favourable IL28B genotypes, acute symptoms and in women. The remaining 75% of patients progress to chronic HCV infection and are subsequently at risk of progression to hepatic fibrosis, cirrhosis and HCC. Chronic hepatitis C generally progresses slowly in the initial two decades, but can be accelerated during this time as a result of advancing age and co-factors such as heavy alcohol intake and HIV co-infection.

Abstract
BACKGROUND & AIMS Age is the dominant prognostic factor influencing the natural history of hepatitis C virus (HCV) infection and treatment response. Accelerated lymphocyte telomere shortening in HCV infection correlates with adverse clinical outcomes. Critical telomere shortening generates double-stranded DNA breaks (DSB) inducing the DNA damage response, leading to replicative senescence. The phenotype and function of CD8+ T lymphocytes and the in vitro response to IFN-α in relation to the DNA damage response were investigated in patients with chronic HCV infection. METHODS CD8+ T lymphocytes with DSB were identified by expression of γ-H2AX (Ser-139) in 134 HCV-exposed subjects and 27 controls. Telomere length was determined by flow-FISH; cytokine expression by intracellular cytokine staining; in vitro responses to IFN-α, IL-2 or IL-6 by phospho-STAT1 (Y701) or phospho-STAT5 (Y694) expression. RESULTS The proportion of circulating CD8+γ-H2AX+ T lymphocytes rose with increasing fibrosis stage (p=0.0023). CD8+γ-H2AX+ T lymphocytes were enriched in liver compared to blood (p=0.03). CD8+γ-H2AX+ T lymphocytes demonstrated increased IFN-γ (p=0.02) and reduced IL-2 expression (p=0.02). CD8+γ-H2AX+ T lymphocytes failed to phosphorylate STAT1 in response to IFN-α compared to unfractionated CD8+ T lymphocytes (p <0.0001). More widespread failure of Jak/Stat signalling in CD8+γ-H2AX+ T lymphocytes was suggested by impaired phosphorylation of STAT1 with IL-6 (p=0.002) and STAT5 with IL-2 (p=0.0039) compared to unfractionated CD8+ T-lymphocytes. CONCLUSIONS In chronic HCV infection, CD8+γ-H2AX+ T lymphocytes are highly differentiated with shortened telomeres, are more frequent within the liver, are associated with severe fibrosis and fail to activate Jak/Stat pathways in response to IFN-α, IL-2 or IL-6, perhaps explaining treatment failure in those with severe fibrosis.

Abstract
BACKGROUND Iron overload and hepatitis-C virus (HCV) infection, have been implicated in the evolution of liver disease, in patients with transfusion-dependent beta-thalassaemia major (BTM). However, the impact of these factors in late stages of liver disease in adults with BTM, has not been extensively studied. AIMS To investigate serum indices of iron overload, HCV infection and liver disease, in a cohort of 211 adult Greek patients with BTM, in relation with the findings from liver biopsies. METHODS In this cross-sectional study, 211 patients with BTM were enrolled and studied, in relation with HCV infection, ferritin, transaminases, chelation treatment and antiviral treatment. Based on 109 patients biopsied, we correlated liver fibrosis, haemosiderosis and inflammation, with serum indices and HCV status RESULTS Among all patients, 74.4% were anti-HCV positive (HCV+). Ferritin was positively correlated with transaminases and negatively correlated with age, while it was not significantly different among HCV+ and HCV- patients. Among the HCV+ patients, 55.4% reported antiviral treatment, while genotype 1 predominated. In a subfraction of 109 patients, in which liver biopsy was performed, 89% were HCV+ and 11% HCV-. Fibrosis was significantly correlated with age (P = 0.046), AST (P = 0.004), ALT (P = 0.044) and inflammation (P < 0.001). Advanced fibrosis was present with even minimal haemosiderosis, independently of ferritin values or HCV history. CONCLUSIONS These data suggest that in the late stages of liver disease in BTM patients, iron overload may be the critical determinant, since fibrosis is related to the minimal haemosiderosis, independently of HCV history.

[PMID: 22765955 DOI: 10.1016/j.jpeds.2012.05.002] [Citation(s) in RCA: 52] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/09/2011] [Revised: 03/26/2012] [Accepted: 05/02/2012] [Indexed: 02/07/2023]
Abstract
OBJECTIVE To evaluate the rate of pediatric hepatitis C virus (HCV) case ascertainment relative to the estimated number of actual cases. STUDY DESIGN Data from Florida and United States health departments were used to assess pediatric HCV case ascertainment rates in Florida and nationwide. The percentage of children infected with HCV from Miami-Dade County receiving medical care by a pediatric gastroenterologist was estimated based on data obtained from physician questionnaires. RESULTS From 2000 through 2009, 2007 children were identified as having positive HCV antibody tests in Florida, only 12% of the expected number (n = 12 155). An estimated 1.6% of the expected children with HCV who tested Ab-positive (37 of 1935) were actively followed by a pediatric gastroenterologist in Miami-Dade County, Florida. Across the United States, only 4.9% of the expected cases have been identified. CONCLUSIONS The identification of children infected with HCV in the nation as a whole is grossly inadequate. Only a small fraction of cases are identified. In Florida, less than 2% of children identified receive treatment. Lack of identification and lack of treatment of children infected with HCV constitute critical public health problems. Strategies to increase awareness of HCV infection and to screen at-risk individuals could substantially improve morbidity and mortality while reducing health care costs.

Abstract
Liver disease presents with classic symptoms: fatigue, anorexia that progresses to nausea and vomiting, muscle and joint pain, and jaundice. Its most common cause is viral infection (hepatitis) with one of the hepatotropic hepatitis viruses. Although all types of hepatitis cause liver disease, their modes of transmission differ, and treatment may or may not be an option. In all types of hepatitis, people older than 65 years of age tend to develop more severe disease than those who are younger. Hepatitis A is rare in the United States, usually resolves completely with rest and supportive care, and there is no drug treatment. The Food and Drug Administration has approved several medications for hepatitis B, although comorbidities in the elderly may preclude their use. Hepatitis C is generally treated with interferon alpha and ribavirin in patients who can tolerate these agents. Chronic hepatitis D infection is more aggressive than chronic hepatitis B infection, leading to cirrhosis within two years in 10% to 15% of patients. Treatment with interferon for at least one year is recommended, but may not help. Hepatitis E virus infection-typically associated with large waterborne epidemics and endemic in Asia, Africa, and Mexico-is poorly understood and reported only sporadically in the United States. Consultant pharmacists can provide invaluable input concerning management of patients with hepatitis since few guidelines are available. Treatment is complex and often associated with side effects, and it is costly to treat. Complete adherence is critical. Residents, their families, and long-term care staff will need education and support in treating these patients. Pharmacist involvement is especially important as newly approved agents become available; side effects can cause clinicians and patients to abandon treatment.

Abstract
As life expectancy continues to rise, elderly adults represent a rapidly growing proportion of the population. The likelihood of complications of acute and chronic liver disease and overall mortality are higher in elderly populations. Several physiological changes associated with aging, greater prevalence of co-morbid conditions, and cumulative exposure to hepatotropic viruses and environmental hepatotoxins may contribute to worse outcomes of viral hepatitis in the elderly. Although pharmacotherapy for hepatitis B and C continues to evolve, the efficacy, tolerability, and side effects of these agents have not been studied extensively in elderly adults. Immunization against hepatitis A and B in naïve elderly adults is an important public health intervention that needs to be revised and broadened.

Assessment of disease progression in patients with transfusion-associated chronic hepatitis C using transient elastography. World J Gastroenterol 2012; 18:1385-90. [PMID: 22493553 PMCID: PMC3319966 DOI: 10.3748/wjg.v18.i12.1385] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/12/2011] [Revised: 08/01/2011] [Accepted: 01/22/2012] [Indexed: 02/06/2023] Open
Abstract
AIM To evaluate the relationship between liver stiffness and duration of infection in blood transfusion-associated hepatitis C virus (HCV) patients with or without hepatocellular carcinoma (HCC). METHODS Between December 2006 and June 2008, a total of 524 transfusion-associated HCV-RNA positive patients with or without HCC were enrolled. Liver stiffness was obtained noninvasively by using Fibroscan (Echosens, Paris, France). The date of blood transfusion was obtained by interview. Duration of infection was derived from the interval between the date of blood transfusion and the date of liver stiffness measurement (LSM). Patients were stratified into four groups based on the duration of infection (17-29 years; 30-39 years; 40-49 years; and 50-70 years). The difference in liver stiffness between patients with and without HCC was assessed in each group. Multiple linear regression analysis was used to determine the factors associated with liver stiffness. RESULTS A total of 524 patients underwent LSM. Eight patients were excluded because of unsuccessful measurements. Thus 516 patients were included in the current analysis (225 with HCC and 291 without). The patients were 244 men and 272 women, with a mean age of 67.8 ± 9.5 years. The median liver stiffness was 14.3 kPa (25.8 in HCC group and 7.6 in non-HCC group). The patients who developed HCC in short duration of infection were male dominant, having lower platelet count, with a history of heavier alcohol consumption, showing higher liver stiffness, and receiving blood transfusion at an old age. Liver stiffness was positively correlated with duration of infection in patients without HCC (r = 0.132, P = 0.024) but not in patients with HCC (r = -0.103, P = 0.123). Liver stiffness was significantly higher in patients with HCC than in those without in each duration group (P < 0.0001). The factors significantly associated with high liver stiffness in multiple regression were age at blood transfusion (P < 0.0001), duration of infection (P = 0.0015), and heavy alcohol consumption (P = 0.043). CONCLUSION Although liver stiffness gradually increases over time, HCC develops in patients with high stiffness value regardless of the duration of infection.

Abstract
BACKGROUND AND AIMS Commercial plasma donation was introduced in China in the 1970s. Cases of non-A, non-B hepatitis (hepatitis C) continued to occur, with multiple outbreaks among plasma donors in Guan county, Hebei province between 1972 and 1990. The outcomes of hepatitis C virus (HCV) infection in these paid plasma donors from six villages of Guan county were followed up for 12-19 years. METHODS A total of 402 plasma donors with HCV infection were enrolled since anti-HCV-positive in 1991 or 1998. Follow up was maintained until death or the end of the observation period. No antiviral treatment was applied during the period of infection. RESULTS Follow up was lost in 23 cases. After a 12-19-year follow up, 31 donors died, with the cause of death directly related to liver disease in 15 cases, and an overall mortality of 8.18% (31/379). The incidence of liver cirrhosis was 10.03%, and hepatocellular carcinoma (HCC) was 2.90%. The rate of viral spontaneous clearing was 20.32% (77/379), and 13.69% (23/168) in males and 25.59% (54/211) in females. In May 2010, detections were performed in 348 cases. Abnormality of liver function was related to HCV viremia. Sex and alcohol intake impacted the outcome of HCV infection. There was no correlation between the viral spontaneous clearance with age of infection and genotype. CONCLUSIONS This area has a high rate of chronicity in HCV infection due to plasma donation. Twenty-five years after virus infection, liver cirrhosis or HCC developed in one-tenth of patients, with an overall mortality of 8.18%.

Abstract
BACKGROUND The outcome of patients with hepatitis C virus (HCV) infection acquired during childhood in the absence of antiviral therapy is not clear. AIMS The purpose of this study was to review the outcome of untreated HCV acquired in childhood. Only population-based studies were included, as referred cases would be predicted to have more severe disease. METHODS A systematic review of the literature was completed up to October 2010 to identify studies where a population was screened for HCV infection that was presumably acquired during childhood. Demographical and clinical data were collected on infected patients who had not been treated with an antiviral. Primary outcome was development of a severe adverse outcome (cirrhosis, hepatoma, need for a liver transplant or liver-related death). RESULTS There were 25 studies reporting a total of 733 infected patients. Liver biopsy results were provided for 180 patients (25%), revealing cirrhosis in eight (1.0% of the total and 4.0% of those who had a biopsy). None of the other patients developed a severe adverse outcome. As a result of the small number of patients with a severe adverse outcome, risk factors for HCV progression could not be identified. CONCLUSION Although HCV can lead to liver transplantation and death during childhood, the vast majority of patients with disease acquired during childhood have slowly progressive disease. There is no clear indication for antiviral therapy in the majority of children with HCV infection.
