Of the remaining 91 reports, 11 were excluded because they were review papers (n = or editorials and author responses (n = 3). Hence, a total of 80 articles were eligible for inclusion. The magnitude of the risk of sexual transmission of HCV was assessed by presenting the adjusted odds ratios (aORs) obtained from the studies that controlled for the most common routes of HCV transmission. Studies addressing heterosexual transmission of HCV distinguished among three types of sexual contacts: sexual contacts within regular partnerships; sexual contacts with multiple partners; and sexual contacts

among persons with preexisting sexually Pexidartinib mw transmitted infections (STIs) and/or human immunodeficiency virus (HIV). Table 1 summarizes major studies that assessed the risk of heterosexual CB-839 transmission of HCV infection among these different groups. Several large prospective cohort studies did not show an increased risk for HCV transmission among heterosexual discordant couples (married or steady

partners), even after 10 or more years of observation. 21-24 In these studies combined, there was no increased risk of sexual transmission of HCV, even after an estimated 750,000 vaginal and anal contacts between couples; accordingly, the probability of such transmission was less than 1 in 10 million sex contacts. Cross-sectional studies reported HCV prevalence rates among

regular partners of infected persons varying between 2% and 10%. 21, 25, 26 However, no association was found between HCV infection and sexual transmission between partners 上海皓元医药股份有限公司 in regular relationships after controlling for other risk factors. 25-32 Three studies documented the presence of the same virus in very few couples by molecular analysis and attributed this to sexual transmission of HCV, 33-35 but could not definitely exclude other common exposures. A potentially confounding factor in the sexual transmission of HCV in heterosexual couples is the duration of the relationship, an index of the number of sexual exposures to HCV from an infected partner. Whereas a few studies found an increased risk of acquiring HCV infection with a longer relationship, 28, 35-37 other larger studies that controlled for age did not find a significant association between the duration of the relationship and HCV infection. 26, 27, 38, 39 The higher prevalence of HCV infection in older couples may represent a cohort effect (in which couples of the same age might be exposed to common sources of infection or common practices, such as the reuse of nondisposable but contaminated medical equipment), as was reported in Spain 40 and Taiwan. 41 Unlike couples in regular relationships, persons having multiple sexual partners have more than twice the likelihood of acquiring HCV infection (aOR 2.2-2.9).

ERBB3-dependent signaling apparently plays the crucial role in regulating the motility and invasion

of HCC cells. To examine the roles of EBBB3-dependent signaling in the tumor development and growth of HCC, we examined the biological consequences of aberrant activation or suppression of ERBB3-dependent signaling in hepatocellular carcinogenesis. Although the activation of ERBB3 by treatment with recombinant NRG1 modestly enhanced cell proliferation (Fig. 7A,B), the silencing of ERBB3, HER2, or both did not suppress the proliferation of HCC cells (Fig. 7C,D). We then examined the biological effects of ERBB3-dependent signaling on the tumor formation and growth of HCC. Neither the activation of ERBB3-dependent ABT-888 concentration signaling via treatment with recombinant NRG1 nor the silencing of the expression of ERBB3, HER2, or both in Huh7 and SK-Hep1 cells significantly suppressed tumor sphere formation in soft agar assays (data Proteases inhibitor not shown). The silencing of EGFR expression did not significantly inhibit tumor sphere formation either (data not shown). On the other hand, xenograft tumor growth of Huh7 and SK-Hep1 cells in nude mice was not significantly suppressed whether the expression of ERBB3 or HER2 had been silenced or not via transduction with lentivirus-based RNA interference (Fig. 7E,F). The silencing

of ERBB3 expression in the xenografts was confirmed with immunoblotting assays (Supporting Information Fig. 4). ERBB3-dependent pathways apparently did not have significant effects on the development and growth of HCC in in vitro or in vivo assays. Microscopic vascular invasion of HCC cells is frequently found in surgically removed HCC tumors. Such microscopic vascular invasion is strongly associated with high rates of intrahepatic metastasis and early recurrence of HCC.15-17 However, the mechanisms behind

the high frequency of microscopic vascular invasion have not been well elucidated. In this study, we provide the first direct evidence that ERBB3-dependent signaling contributes to microscopic vascular invasion and intrahepatic metastasis of HCC. First, we found MCE公司 that up-regulation of ERBB3 in HCC was strongly associated with microscopic vascular invasion, early recurrence, and poor prognosis for patients with HCC. Second, we demonstrated that aberrant activation of ERBB3-dependent signaling enhanced the migration and invasion of HCC cells, whereas the suppression of ERBB3-dependent signaling significantly inhibited the migration and invasion of HCC cells. ERBB3-dependent signaling apparently plays a crucial role in the regulation of the invasion and metastasis of HCC. Our findings also suggest that ERBB3 is a marker for the prediction of microscopic vascular invasion, intrahepatic metastasis, and early recurrence.

21, 26–28 Importantly, these NK cells were dominated by activation receptor (NKp30, NKp44, and NKp46) expression, PD-1/PD-L1 inhibitor review whereas inhibitory receptor (CD158a/b) expression was largely decreased in IA patients in comparison with IT/HC subjects. In addition, NK cells from IA patients expressed higher levels of activation markers than NK cells from HC and IT subjects, and this was also mirrored by the functional increase in degranulation and cytolytic activity in IA patients. In combination with

previous reports of HBV-infected patients,13, 19 our findings support the concept that NK cells in vivo are predominantly polarized toward cytolytic activity in IA patients. We then investigated the cause of hepatic NK cell activation in IA patients. NK cell functions are TSA HDAC manufacturer tightly regulated by a variety of cytokines such as IFN-α, IL-12, IL-15, IL-18, and IL-10.29 In this study, we found that IA patients displayed increased expression of IL-12, IL-15, and IL-18 in the liver. Such elevations may be responsible for the elevated NK cell activity in IA patients because of their ability to induce NK activation and polarize them toward degranulation in vitro. Interestingly, hepatic IL-10 expression was largely reduced in IA patients in comparison with IT/HC subjects. IL-10 is a potent immunosuppressive cytokine that has been shown to inhibit NK cell functions

via indirect inhibition of accessory cell (macrophage/monocyte) functions.30 Thus, hepatic IL-12, IL-15, and IL-18 up-regulation in IA patients may potentially activate

NK cells and polarize them toward cytolytic activity, whereas IL-10 reduction in situ may further favor IL-12/IL-15/IL-18–dependent MCE公司 NK cell cytolytic activity. IFN-α, another important cytokine regulating NK activity, has been implicated in inducing NK cell activation in patients with chronic HCV infection.14 The studies from Dr. Rehermann’s laboratory have demonstrated that IFN-α levels are elevated in the livers of patients with chronic HCV infection and that in vitro treatment with IFN-α results in increased NK cell expression of TRAIL and CD107a but not IFN-γ; this clearly suggests that elevated IFN-γ is responsible for the up-regulation of NK cell activity in the livers of HCV patients. Although the elevation of IFN-α responses is well documented during HCV infection,31, 32 the results regarding IFN-α responses during HBV infection have been controversial, and most studies have reported a lack of IFN-α responses after HBV infection.33, 34 For example, Fisicaro et al.17 found that acute HBV infection was associated with up-regulation of transient IL-10 expression but not with IFN-α and IL-15 responses. In contrast, in CHB patients with hepatic flares, the cytokine profile was characterized by increased IFN-α and IL-814 as well as chemokine (C-X-C motif) ligand 9 and chemokine (C-X-C motif) ligand 10.

“Most women have used at least 1 method of contraception during their reproductive years, with the majority favoring combined oral contraceptives. Women are often concerned about the safety of their method of choice and also ask about likely effects on their pre-existing headache or migraine and restrictions on using their headache medication. While there should

be no restriction to the use of combined hormonal contraceptives by women with migraine without aura, the balance of risks vs benefits for women with aura are debatable. Migraine with aura, but not migraine without aura, is associated with a twofold increased risk of ischemic stroke, although the absolute risk is very low in Ivacaftor order healthy, nonsmoking women. Although ethinylestradiol has been associated with increased risk of ischemic stroke, the risk is dose-dependent. Low-dose pills currently used are considerably safer than pills containing higher doses of ethinylestradiol but they are not risk-free. This review examines the evidence available click here regarding the effect that different methods of contraception have on headache and migraine and identifies strategies available to minimize risk and to manage specific triggers such as estrogen “withdrawal” headache and migraine associated with combined hormonal contraceptives. The independent risks of ischemic stroke

associated with migraine and with hormonal contraceptives are reviewed, and guidelines for use of contraception by women with migraine MCE are discussed in light of the current evidence. “
“Spontaneous intracranial hypotension typically results from spontaneous cerebrospinal fluid (CSF) leak, often at spine level and only rarely from skull base. Once considered rare, it is now diagnosed far more commonly than before and is recognized as an important cause of headaches. CSF leak leads to loss of CSF volume. Considering that the skull is a rigid noncollapsible container, loss

of CSF volume is typically compensated by subdural fluid collections and by increase in intracranial venous blood which, in turn, causes pachymeningeal thickening, enlarged pituitary, and engorgement of cerebral venous sinuses on magnetic resonance imaging (MRI). Another consequence of CSF hypovolemia is sinking of the brain, with descent of the cerebellar tonsils and brainstem as well as crowding of the posterior fossa noted on head MRI. The clinical consequences of these changes include headaches that are often but not always orthostatic, nausea, occasional emesis, neck and interscapular pain, cochleovestibular manifestations, cranial nerve palsies, and several other manifestations attributed to pressure upon or stretching of the cranial nerves or brain or brainstem structures. CSF lymphocytic pleocytosis or increase in CSF protein concentration is not uncommon. CSF opening pressure is often low but can be within normal limits.

In the immune-associated liver disease, more evidence is needed for etiology clarification and treatment before transplantation.

Presenting Author: MOHAMMADREZA ABDOLLAHI Additional BIBW2992 Authors: MOHAMMADHOSSEIN SOMI Corresponding Author: MOHAMMADREZA ABDOLLAHI Affiliations: Young Researchers and Elite Club, Tabriz Branch, Islamic Azad University; Liver and Gastrointestinal Diseases Research Center, Tabriz University of Medical Sciences Objective: Autoimmune hepatitis (AIH) is an unresolving inflammation of the liver of unknown cause. It is characterized by the presence of interface hepatitis and portal plasma cell infiltration on histologic examination, hypergammaglobulinemia, and autoantibodies. One of widely used criteria for diagnosis is International Autoimmune Hepatitis Group selleck chemicals llc (IAHG) recommendation. This study aimed at evaluating the clinical and paraclinical characteristics of AIH, comparing them with IAHG criteria. Methods: Sixty consecutive patients with AIH recuirted from university clinic in Tabriz University of medical science, Tabriz, Iran from Jan-2011 to Dec-2011. Patients were evaluated by reviewing demographic, physical examination and complete blood count (CBC). Serological and biochemical evaluation were done and the frequency of autoantibodies like antinuclear antibody (ANA), anti-smooth muscle antibody (ASMA), anti-liver-kidney microsomal

antibody (ALKM-1) type 1 and perinuclear anti-neutrophil cytoplasmic antibodies (P-ANCA) were evaluated. Liver biopsy was done for all of the patients for diagnosing of the AIH. We used both comprehensive and simplified diagnostic scoring system for autoimmune hepatitis in this study. Results: Out of Sixty patients, 40 females, with the mean age of 39.45 ± 17.50 years, all enrolled patients were treated with prednisone and azathioprine. Percentile distribution of the study population into definite and probable did not change after the treatment. The most common sign and symptoms in descending order were fatigue

(100%), icter (66.7%), abdominal discomfort (33.3%), abdominal distension (28.3%), dark urine (23.3%), edema (23.3%), haematemesis (20.0%), pruritus (20.0%), melena (11.7%) and pale stool (10.0%). ALKM-1, P-ANCA, ANA and ASMA were positive in 71.4%, 66.7%, 42.4% and 19.4% cases, respectively. Due MCE to paraclinical study findings, portal hypertensive gastropathy (45.0%), esophageal varices (41.7%) and cirrhosis (40.0%) were the most complications of autoimmune hepatitis in patients and there was not any evidence of primary sclerosing cholangitis, ulcerative colitis and overlap syndrome in these patients. According to IAHG, 80.0% of cases had definite diagnosis, 15.0% of cases had probable diagnosis and 5.0% of cases no AIH. Percentile distribution of the study population into definite, probable and no AIH did not changed after using simplified diagnostic scoring system for autoimmune hepatitis.

Approximately 40∼50% of East Asians carry an inactive ALDH2 gene and exhibit acetaldehyde accumulation after alcohol consumption. However, the role of ALDH2 deficiency in the pathogene-sis of alcoholic liver injury remains obscure. METHODS: Wild-type (WT) and ALDH2-/- mice were subjected to ethanol feeding and/or carbon tetrachloride (CCl4) treatment, and liver injury was assessed. RESULTS: Compared with WT mice, ethanol-fed ALDH2-/- mice had higher levels of malondialde-hyde and acetaldehyde (MAA) adduct and greater hepatic inflammation, with higher hepatic interleukin-6 (IL-6) expression but surprisingly lower levels

of steatosis and serum alanine transaminase (ALT). Higher IL-6 levels were also detected in ethanol-treated, precision-cut liver slices from ALDH2-/- mice and in Kupffer cells isolated from ethanol-fed ALDH2-/- mice than those levels in WT mice. In vitro incubation with MAA enhanced the LPS-mediated Small molecule library stimulation of IL-6 production in Kupffer cells. In agreement with these findings, hepatic activation of the major IL-6 downstream signaling molecule signal transducer and activator of transcription 3 (STAT3) was higher in ethanol-fed ALDH2-/- mice than in WT mice. An additional deletion of hepatic STAT3 resulted in teatosis and hepatocellu-lar damage in ALDH2-/- mice. Finally,

ethanol-fed ALDH2-/-mice were more prone to CCl4-induced liver inflammation and fibrosis than ethanol-fed WT mice. CONCLUSIONS: ALDH2-/-mice are resistant to ethanol-induced steatosis MCE公司 but prone to inflammation and fibrosis via MAA-mediated paracrine activation of IL-6 in Kupffer cells. These findings suggest that individuals who have ALDH2 deficiency may be resistant R788 clinical trial to steatosis, but are more prone to liver inflammation and fibrosis following alcohol consumption.

Kawamoto, Mohamed A. Abdelmegeed, Byoung-Joon Song, Vasilis Vasiliou, Geoffrey M. Thiele, Bin Gao Background: Under physiological state, free fatty acids (FFA) enter adipocytes and stored in the adipose tissues in the form of triglycerides (TG). Patients with alcoholic liver disease have been shown to have significantly lower percentage of body fat (%BF). This results in reducing TG storage as reflected by increasing serum FFA. In adipose tissue, Pref-1 is specifically expressed in preadipocytes but not in adipocytes. Increasing Pref-1 leads to inhibition of adipogenesis and reduced adipose tissue mass. Our aim is to investigate the association between alcohol consumption, serum Pref-1, and %BF in heavy drinkers compared to controls. Methods: 97 chronic heavy drinkers (mean age 41.3 years/69% men/81% Caucasian) were enrolled from Fairbanks Alcohol Treatment Center. 51 non-heavy drinkers (mean age 31.8 years/88% men/84% Caucasian) were recruited from Roudebush VAMC.

Defect or deficiency in FVIII causes haemophilia A, a severe hereditary bleeding disorder. ubiquitin-Proteasome system Intravenous administration of plasma-derived FVIII or recombinant FVIII

concentrates restores normal coagulation in haemophilia A patients and is used as an effective therapy. In this work, we studied the biophysical properties of clinically potent recombinant FVIII forms: human FVIII full-length (FVIII-FL), human FVIII B-domain deleted (FVIII-BDD) and porcine FVIII-BDD bound to negatively charged phospholipid vesicles at near-physiological conditions. We used cryo-electron microscopy (Cryo-EM) as a direct method to evaluate the homogeneity and micro-organization of the protein-vesicle suspensions, which are important for FVIII therapeutic properties. Applying concurrent Cryo-EM, circular dichroism and dynamic light scattering studies to the three recombinant FVIII high throughput screening compounds forms when bound to phospholipid vesicles revealed novel properties for their functional, membrane-bound state. The three FVIII constructs have similar activity, secondary structure distribution and bind specifically to negatively charged phospholipid membranes. Human and porcine FVIII-BDD induce strong aggregation of the vesicles, but the human FVIII-FL form does not. The proposed methodology is effective in characterizing and identifying

differences in therapeutic recombinant FVIII membrane-bound forms near physiological conditions, because protein-containing aggregates are considered to be a factor in increasing the immunogenicity of protein therapeutics. This will provide better characterization and development of safer and more effective FVIII products with implications for haemophilia A treatment. “
“Summary.  Inhibitors of factor VIII (FVIII) have been studied for more than 50 years, but diagnostic 上海皓元 and therapeutic challenges remain. To describe the features that distinguish alloantibodies from autoantibodies, list predisposing factors, and review methods for tolerance induction and autoantibody suppression. Review of key articles published during the past half-century that have advanced knowledge in this field. Alloantibodies generally bind to the A2

or C2 domains of FVIII and disrupt the formation of the FVIII–FIX complex. They exhibit type 1 reaction kinetics, are saturable by FVIII, and display anamnesis. In contrast, autoantibodies usually bind to the C2 domain of FVIII, interfering with phospholipid and von Willebrand factor binding. They have type-2 kinetics and are poorly neutralized by FVIII. Repeated exposures to FVIII induce tolerance in 70–80% of haemophiliacs with inhibitors, whereas drugs that deplete B-lymphocytes restore self-tolerance to FVIII in a similar percentage of non-haemophiliacs. Future work should focus on improving assays that detect and quantify inhibitors, examining the pathophysiology of inhibitor formation using contemporary immunologic tools, and investigating new treatment modalities.

The one presented randomized controlled trial examining the interaction between clopidogrel and omeprazole demonstrated no adverse interaction, and in fact demonstrated a positive relationship between PPI use in patients co-prescribed clopidogrel and prevention of gastro-intestinal bleeding; however, the conclusions are somewhat limited by the fact the study was terminated prematurely. Obviously there is a need further randomized controlled studies to definitively establish the nature of the interaction between PPI and clopidogrel. In

the interim it seems prudent to prescribe PPI in patients on clopidgrel only when there are sound clinical indications, to utilize PPIs that are less metabolized through the 2C19 pathway, although the evidence for this is limited, to administer clopidogrel with find more food and consider taking the PPI at a time remote (∼ 5 h) from that of the clopidogrel dosing. While we anticipate further prospective studies, this is clearly a case for watchful waiting. “
“Management of hepatitis C virus

(HCV) recurrence is a major challenge after liver transplantation. Significant dysregulated expression of HCV receptors (i.e. claudin-1, occludin, tetraspanin CD81, mTOR inhibitor scavenger receptor type B1) has been shown recently during HCV infection. This might facilitate hepatocytic entry and reinfection of HCV. MicroRNAs (miRs) play role in the regulation of gene expression. We aimed to characterize

miR expression profiles related to HCV infection and antiviral therapy in adult liver transplant recipients, with special emphasis on miRs predicted to target HCV receptors. Twenty-eight adult liver transplant recipients were enrolled in the study. Paired biopsies were obtained at the time of HCV recurrence and at the end of antiviral treatment. MiRs for HCV receptors were selected using target prediction software. Expression levels of miR-21, 上海皓元医药股份有限公司 miR-23a miR-34a, miR-96, miR-99a*, miR-122, miR-125b, miR-181a-2*, miR-194, miR-195, miR-217, miR-221, and miR-224 were determined by reverse transcription–quantitative polymerase chain reaction. miR-99a* and miR-224 expressions were increased in HCV recurrence samples, while miR-21 and miR-194 were decreased in comparison to normal liver tissue. Increased expressions of miR-221, miR-224, and miR-217 were observed in samples taken after antiviral therapy when compared with HCV recurrence samples. High HCV titer at recurrence was associated with higher level of miR-122. Samples at recurrence of HCV and after antiviral therapy revealed distinct HCV-related miR expression profiles, with significant dysregulation of those miRNAs potentially targeting mRNAs of HCV receptors. In particular, miR-194 and miR-21 might be involved in the regulation of HCV receptor proteins’ expression during HCV infection and antiviral therapy.

71 [95% CI = 3.47-17.10]; adjusted for D-MELD > 1600, HR = 7.81 [95% CI = 3.52-17.33], both P < 0.001). None of the remaining six patients without a genetic (mis)match had died during follow-up. The presence of common functional gene polymorphisms in MBL2,

FCN2, and MASP2, which affect the composition, structure, Navitoclax datasheet and function of the respective proteins, was found to confer an increased risk of CSI after liver transplantation. Thus, the multifactorial antimicrobial lectin complement activation pathway is of eminent importance to the risk of bacterial infections such as sepsis, peritonitis, and pneumonia, after OLT. Earlier studies already indicated that MBL deficiency of the donor liver is accompanied by an increased

risk of infections after liver transplantation.10, 11 We now showed that the minor T-allele of FCN2 SNP rs17549193 (+6359CT) and homozygosity check details for the major A-allele, or the absence of the minor allele, of MASP2 SNP rs12711521 (+371AC), which are the other main components of the lectin complement activation pathway, also have a significant impact on this infection risk. Diverse combined SNPs in the MBL2 gene, in conjunction with SNPs in the FCN2 and MASP2 genes of the donor liver, constitute a genetic profile of the lectin complement activation pathway which carry a gene dose-dependent risk for bacterial infection in the first year after OLT, as demonstrated and confirmed in the two separate cohorts. The recipient lectin complement pathway gene profile seemed not to convey a major clinical

risk itself. However, MBL-sufficient recipients receiving an MBL-insufficient donor liver were found to be at high risk for these infections. In addition, combined donor and recipient FCN2 and MASP2 genotype analyses showed that when there is no match in the allele associated with reduced infection, the relative risk of CSI is also highly increased. The essential components of the lectin pathway of complement activation that we studied are mainly produced in the 上海皓元 liver.10, 22 After liver transplantation, the adaptive immunity of the recipient is reduced by immunosuppression and the recipient will, to a major extent, be dependent on the lectin complement activation pathway of the donor liver. The functional SNPs in these polymorphic genes may thus lead to reduced complement activation and opsonization, which results in increased susceptibility to infections in patients with an immature or compromised adaptive immune system. Our study is the first to show that the interplay between the genotype of three members of the lectin complement pathway in both donor and recipient has a major impact on the risk of developing infections and on related death in immunocompromised OLT recipients.

Incidence rates of diabetes mellitus were compared between subjects with and without NAFLD at baseline. Out of 2984 subjects, 926 had NAFLD and 676 had diabetes in 2007. Of the 2276 subjects who were free of diabetes in 2007, 1914 were re-assessed in 2010. After 3 years, 104 out of 528 subjects with NAFLD and 138 out of 1314 subjects without NAFLD selleckchem had developed diabetes mellitus de novo. Incidence rates of diabetes were respectively 64.2 and

34 per 1000 person-years of follow up for those with and without NAFLD. NAFLD was an independent predictor of developing diabetes mellitus. Other independent predictors were impaired fasting glycemia and dyslipidemia. Subjects with ultrasonically diagnosed NAFLD have an increased risk of developing diabetes mellitus. Intervention for NAFLD through lifestyle modification may prevent progression of the current diabetes epidemic. “
“Purpose: Sofosbuvir (SOF) and simeprevir (SMV) based therapies for chronic hepatitis C virus (HCV) infection offer highly efficacious, safer but substantially more expensive options than the old standard-of-care (oSOC). The population-level economic impact of the uptake of new treatments and resulting downstream cost savings remain unknown. Tyrosine Kinase Inhibitor Library order Our objective was to estimate the resources needed to treat all eligible HCV-patients with new drugs in the next 5 years and resulting downstream cost-savings. Method: We

developed a validated Markov microsimulation

model that simulated MCE the natural history of HCV. We included both treatment-naive and treatment-experienced patients and defined baseline population based on HCV genotype, age and fibrosis distribution of the HCV-in-fected population in the United States. We simulated SOF/ SMV-based therapies as recommended by a recently published AASLD-IDSA guideline, as well as the oSOC that consisted of either first-generation protease inhibitors or peginterferon-ribavirin based therapies. We used published clinical trials data to derive efficacy estimates for SOF, SMV, and the oSOC. Health-state specific annual costs and treatment costs were estimated from published sources. Using a validated prediction model of HCV disease burden in the United States and NHANES study, we estimated the number of people who will be eligible for treatment in the next 5 years and the resources needed to treat them. Results: In 2014, 1.32 million treatment-naive and 0.45 million treatment-experienced people would be aware of their HCV disease. In addition, 0.51 million people would be diagnosed in the next 5 years because of risk-based and birth-cohort HCV screening. We estimated that a total of 1.60 million people with insurance coverage would be eligible for treatment during the next 5 years. Payers would need $188 billion to cover drug costs of all treatment-eligible HCV patients during the next 5 years.
