Abstract
The hepatitis C virus (HCV) infection affects 58 million people worldwide. In the United States, the incidence rate of acute hepatitis C has doubled since 2014; during 2021, this increased to 5% from 2020. Acute hepatitis C is defined by any symptom of acute viral hepatitis plus either jaundice or elevated serum alanine aminotransferase (ALT) activity with the detection of HCV RNA, the anti-HCV antibody, or hepatitis C virus antigen(s). However, most patients with acute infection are asymptomatic. In addition, ALT activity and HCV RNA levels can fluctuate, and a delayed detection of the anti-HCV antibody can occur among some immunocompromised persons with HCV infection. The detection of specific biomarkers can be of great value in the early detection of HCV infection at an asymptomatic stage. The high rate of HCV replication (which is approximately 1010 to 1012 virions per day) and the lack of proofreading by the viral RNA polymerase leads to enormous genetic diversity, creating a major challenge for the host immune response. This broad genetic diversity contributes to the likelihood of developing chronic infection, thus leading to the development of cirrhosis and liver cancer. Direct-acting antiviral (DAA) therapies for HCV infection are highly effective with a cure rate of up to 99%. At the same time, many patients with HCV infection are unaware of their infection status because of the mostly asymptomatic nature of hepatitis C, so they remain undiagnosed until the liver damage has advanced. Molecular mechanisms induced by HCV have been intensely investigated to find biomarkers for diagnosing the acute and chronic phases of the infection. However, there are no clinically verified biomarkers for patients with hepatitis C. In this review, we discuss the biomarkers that can differentiate acute from chronic hepatitis C, and we summarize the current state of the literature on the useful biomarkers that are detectable during acute and chronic HCV infection, liver fibrosis/cirrhosis, and hepatocellular carcinoma (HCC).

Abstract
OBJECTIVES HIV, hepatitis C virus (HCV), and human T-cell lymphotropic virus type 1 (HTLV-1) share the same routes of infection, making coinfection by these viruses a frequent finding in endemic areas. However, there is scarce information on the clinical/immunological consequences of triple infection. Coinfection by HTLV-1 is able to modulate cytokine's production in patients with HIV, but there are no data on the immune response of HIV-HCV-HTLV-1-infected patients. METHODS We compared the plasma levels of 25 different cytokines in patients with HIV-HCV, according to their serostatus to HTLV-1 infection. Eligible patients should be on stable highly active antiretroviral therapy and have undetectable HIV-1 plasma viral load for, at least, 12 months. Cytokines levels were also evaluated by CD4 cells count, rates of sustained virological response (SVR) to previous HCV treatment, frequency of spontaneous HCV clearance, and HCV/IFN-λ3 genotypes. RESULTS Twenty-five patients (15 coinfected by HIV and HCV, 10 coinfected by HIV, HCV, and HTLV-1) were evaluated. Among the triply infected group, 3 had undetectable HCV viremia (spontaneous clearance). All but one remaining patients were previously treated for HCV, with similar SVR rates (∼29%). Cytokines levels did not differ per HCV/IFN-λ3 genotypes, mean CD4 cells count, age, sex, or SVR. However, patients coinfected by HTLV-1 showed significantly higher levels of IL-1b, IL-2, TNF-α, IFN-γ, MIP-1α, RANTES, and interferon-induced protein 10 (IP-10) than HIV-HCV-coinfected ones. Patients presenting HCV spontaneous clearance had the highest levels of cytokines. CONCLUSIONS Coinfection by HTLV-1 increases the plasma levels of proinflammatory cytokines of patients with HIV-HCV and can influence the outcomes of coinfected patients.

Abstract
AIM To investigate interferon-γ-inducible protein-10’s (IP-10) potential to anticipate rapid (RVR)- and sustained virological responses (SVR) to chronic hepatitis C (CHC) treatment.
METHODS We included case series examining RVR or SVR in relation to 24 or 48 wk treatment for CHC, in patients treatment free for at least six months, with genotype 1 or 4, and in relation to 24 wk treatment for genotype 2 and 3, with pegylated interferon in combination with ribavirin. Patients had to have both a baseline IP-10 level as well as a hepatitis C virus (HCV)-RNA determination 4 wk after treatment initiation or 24 wk after end of treatment. Studies including patients with liver diseases other than CHC, human immunodeficiency virus-infection, treatment with immunosuppresents or cytostatica, alcohol dependency or active intravenous drug-use were excluded. We found 81 articles by searching the MEDLINE and EMBASE databases. Eight studies were eligible for inclusion. Their quality were assesed using an 18 point checklist for case series, developed using a modified Delphi technique. Information was extracted from the articles, and no raw data was requisitioned. The review protocol was registered at the International Prospective Register of Systematic Reviews (reg. number: CRD42014008736).
RESULTS Three studies reported on baseline IP-10 level in association with RVR. A signigficant association was found for HCV genotype 1 infection by two studies. Only two studies reported on HCV genotype 4 infected and genotype 2 and 3 infected patients, respectively. A trend was seen for an association between RVR and baseline IP-10 for genotype 4, while no association was found for genotype 2 and 3. Seven studies provided information regarding baseline IP-10 and SVR. Following the pattern regarding rapid virological response all five studies examining SVR in relation to baseline IP-10 levels for HCV, genotype 1 infected patients showed a significant association. Likewise a significant association was seen for HCV, genotype 4 infected, while no association was found for HCV, genotype 2 and 3 infected. Though only two studies examined the assosiation for HCV genotype 4 infected and HCV genotype 2 and 3 infected respectively.
CONCLUSION We found indications of a possible association between baseline IP-10 level and virological responses in patients with CHC genotype 1 and 4.

Abstract
BACKGROUND/AIMS Several studies have demonstrated that serum interferon-γ-inducible-protein-10 (IP-10) levels at baseline and single nucleotide polymorphisms (SNPs) near the IL28B gene were associated with viral response and treatment outcomes. Our purpose was to assess the combination of pretreatment IP-10 levels with IL28B SNPs as predictors of treatment response to pegylated interferon α-2a plus ribavirin in patients infected with genotype 1 hepatitis C virus in China. METHODS Seventy-two patients with chronic hepatitis C without fibrosis/cirrhosis were enrolled in the study. The virologic parameters and baseline serum IP-10 levels were determined. IL-28B genotypes were determined by sequencing. RESULTS In this cohort, serum baseline IP-10 levels lower than 426.7 pg/mL could predict rapid virological response/ sustained virological response (SVR). Patients carrying favorable IL28B SNP genotypes had higher SVRs than did those carrying unfavorable variants (IL28B rs12979860, p=0.002; IL28B rs8099917, p=0.020). Combining both baseline IP- 10 and IL28B SNPs could improve the prediction of SVR in favorable allele carriers of IL28B, rs12979860 CC and rs8099917 TT. Serum baseline IP-10 levels and IL28B genotypes were independent predictors of SVR. CONCLUSIONS Our study shows that the combination of baseline serum IP-10 levels and the determination of IL28B SNPs increase the predictability of SVR rates in this cohort.

Abstract
Pretreatment serum levels of interferon-γ-inducible protein-10 (IP-10, CXCL10) and dipeptidyl peptidase-4 (DPP IV) predict treatment response in chronic hepatitis C (CHC). The association between functional genetic polymorphisms of CXCL10 and DPP4 and treatment outcome has not previously been studied. This study aimed to determine the association between genetic variations of CXCL10 and DPP4 and the outcome of treatment with pegylated interferon-α (PEG-IFN-α) based therapy in Thai patients with CHC. 602 Thai patients with CHC treated using a PEG-IFN-α based regimen were genotyped for CXCL10 rs56061981 G>A and IL28B rs12979860 C>T. In addition, in patients infected with CHC genotype 1, DPP4 (rs13015258 A>C, rs17848916 T>C, rs41268649 G>A, and rs 17574 T>C) were genotyped. Correlations between single nucleotide polymorphisms, genotype, and treatment response were analyzed. The rate of sustained virologic response (SVR) was higher for the CC genotype of IL28B rs12979860 polymorphisms than for non-CC in both genotype 1 (60.6% vs. 29.4%, P < 0.001) and non-genotype 1 (69.4% vs. 49.1%, P < 0.05) CHC. SVR was not associated with the CXCL10 gene variant in all viral genotypes or DPP4 gene polymorphisms in viral genotype1. Multivariate analysis revealed IL28B rs12979860 CC genotype (OR = 3.12; 95% CI, 1.72-5.67; P < 0.001), hepatitis C virus RNA < 400,000 IU/ml (OR = 2.21; 95% CI, 1.22-3.99, P < 0.05), age < 45 years (OR = 2.03; 95% CI, 1.11-3.68; P < 0.05), and liver fibrosis stage 0-1 (OR = 1.64; 95% CI, 1.01-2.65, P < 0.05) were independent factors for SVR. Unfavorable IL28B rs12979860 CT or TT genotypes with the CXCL10 rs56061981 non-GG genotype were associated with a higher SVR than GG genotype (66.7% vs. 33.0%, P = 0.004) in viral genotype 1. In Thai CHC genotype 1 infected patients with an unfavorable IL28B rs12979860 CT/TT genotype, the complementary CXCL10 polymorphism strongly enhances prediction of treatment response.

Abstract
Background. The prevalence of occult hepatitis C infection (OCI) in the population of HCV-RNA negative but anti-HCV positive individuals is presently unknown. OCI may be responsible for clinically overt recurrent disease following an apparent sustained viral response (SVR) weeks to years later. Purpose. To review the available current literature regarding OCI, prevalence, pathogenic mechanisms, clinical characteristics, and future directions. Data Sources. Searching MEDLINE, article references, and national and international meeting abstracts for the diagnosis of OCI (1990-2014). Data Synthesis. The long-term followup of individuals with an OCI suggests that the infection can be transient with the loss of detectable HCV-RNA in PPBMCs after 12-18 months or alternatively exist intermittently and potentially long term. The ultimate outcome of HCV infection is decided by interplay between host immune responses, antiviral therapies, and the various well-identified viral evasion mechanisms as well as the presence of HCV infection within extrahepatic tissues. Conclusion. The currently widely held assumption of a HCV-cure in individuals having had "SVR" after 8-12 weeks of a course of DAA therapy as recently defined may not be entirely valid. Careful longitudinal followup utilizing highly sensitive assays and unique approaches to viral isolation are needed.

Abstract
Despite the appearance of the direct acting antiviral drugs, pegylated interferon/ribavirin (PEG-IFN/RBV) still has a place in the standard of care (SOC) therapy for chronic HCV4. Studies were conducted to find an accurate prediction in response to SOC therapy. Pretreatment serum interferon-γ-inducible protein-10 (IP-10) is an independent predictive factor of sustained virological response (SVR) in HCV1-infected patients. To assess whether the pretreatment serum level of IP-10 influences hepatic fibrosis and PEG-IFN/RBV therapy response, a study was conducted on 88 chronic Hepatitis C virus (HCV) patients who received PEG-IFN/RBV. Patients were subjected to a pretreatment routine laboratory evaluation, liver biopsy, and serum IP-10 assessment. They were followed up for 6 months after cessation of therapy (week 72). Patients were classified into 3 groups according to their response; nonresponders, relapsers, or sustained virological responders. The relation of pretreatment IP-10 with fibrosis and response was assessed. The studied groups were matched regarding their demographic data. There was no statistically significant association between the pretreatment IP-10 level and fibrosis (P=0.86) and no relation to response was found at week 12, 24, 48, and 72 (P=0.58, 0.8, 0.47, and 0.43, respectively). Pretreatment IP-10 could not predict either fibrosis or response to PEG-IFN/RIB therapy in chronic HCV Egyptian patients.

Abstract
OBJECTIVE Interferon (IFN)-γ-induced protein-10 (IP-10) serum level has been shown be associated with viral response in chronic hepatitis C (CHC) patients. However, little is known in Chinese population. We determined IP-10 serum levels in Chinese CHC patients undergoing PEG-IFN-based therapy. Predictive role of IP-10 level for virological responses was accessed. MATERIAL AND METHODS IP-10 serum levels were determined in 165 hepatitis C virus (HCV) genotype 1 and 33 genotype 2 patients. Multivariate analysis was performed to screen independent factors for sustained virological response (SVR) prediction. Predictive value of IP-10 level in combination with interleukin 28B (IL28B) genotype or rapid virological response was further investigated. RESULTS Our study showed that pretreatment IP-10 level was significantly higher in HCV genotype 1 patients. IP-10 levels were independently predictive for SVR with cut-off values of 250.60 pg/ml at baseline or 407.40 pg/ml at week 4. Positive predictive value (PPV) for SVR of low IP-10 level at baseline and IL28B CC genotype was 96.15% and negative predictive value (NPV) was 50.00%. PPV for SVR of low IP-10 level at week 4 and rapid viral response (RVR) was 95.24% and NPV was 50.00%. CONCLUSION Together our study indicated that higher IP-10 serum levels were associated with HCV genotype 1 CHC Chinese patients. IP-10 levels at baseline and week 4 were both predictive of SVR and improved predictive performances of IL28B genotype and RVR for SVR.

Abstract
The acute phase of hepatitis C (HCV) infection is typically defined as the initial 6 months following exposure to the virus; however, in some individuals, the acute phase of the infection can last much longer (Orland et al. Hepatology 33:321-27, 2001). Although some patients have symptoms of acute hepatitis, most infected individuals are entirely asymptomatic. As a result, many patients are unaware of the infection until it progresses to chronic infection, and may not develop symptoms until decades later with the onset of decompensated cirrhosis or hepatocellular carcinoma (HCC). A substantial proportion (20-40%) of infected patients clear the virus during the acute phase. Interferon-based treatment is also much more likely to be successful in the acute phase of infection but is relatively poorly tolerated. Therefore, recognition of acute HCV infection is critical to prioritize those patients who do not spontaneously clear the infection for immediate therapy. However, the promise of highly effective well-tolerated all-oral therapies in development may alter the management approach. This review will focus on the epidemiology, natural history, diagnosis, and treatment of acute HCV infection.
