Introduction: With the advent of direct-acting antiviral (DAA) therapy for HCV, the cure is achieved at similar rates among HIV–HCV coinfected patients as in HCV mono-infected patients. The present study evaluates host plasma metabolites as putative indicators in predicting the treatment response in baseline HIV–HCV patients.Methods: Non-cirrhotic HIV–HCV (N = 43) coinfected patients were treated with sofosbuvir and daclatasvir for 12 weeks. Plasma metabolite profiling of pre- and post-therapy was analyzed in 20/43 patients. Of the 20 selected, 10 (50%) attained the sustained viral response [(SVR) (responders)] as defined by the absence of HCV RNA at 12 weeks after the treatment, and 10 (50%) did not attain the cure for HCV (nonresponders).Results: A total of 563 features were annotated (metabolomic/spectral databases). Before therapy, 39 metabolites differentiated (FC ±1.5, p < 0.05) nonresponders from responders. Of these, 20 upregulated and 19 downregulated were associated with tryptophan metabolism, nicotinamide metabolism, and others. Post therapy, 62 plasma metabolites (12 upregulated and 50 downregulated, FC±1.5, p < 0.05) differentiated nonresponders from responders and highlighted a significant increase in the steroid and histidine metabolism and significant decrease in tryptophan metabolism and ascorbate and pyruvate metabolism in the nonresponders. Based on random forest and multivariate linear regression analysis, the baseline level of N-acetylspermidine (FC > 2, AUC = 0.940, Bfactor = −0.267) and 2-acetolactate (FC > 2, AUC = 0.880, Bfactor = −0.713) significantly differentiated between nonresponders from responders in HIV–HCV coinfected patients and was able to predict the failure of treatment response.Conclusion: Increased baseline levels of N-acetylspermidine and 2-acetolactate levels are associated with the likeliness of failure to attain the cure for HCV in HIV–HCV coinfected patients.

Abstract Background The efficacy of licensed direct-acting antiviral (DAA) regimens is assumed to be the same for hepatitis C virus (HCV)–monoinfected patients (HCV-Mono) and HIV/HCV-coinfected patients (HCV-Co). However, the high sustained viral response (SVR) rates of DAA regimens and the small number of HIV-infected patients included in registration trials have made it difficult to identify predictors of treatment failure, including the presence of HIV. Methods We compared treatment outcomes for ledipasvir/sofosbuvir (LDV/SOF) against HCV G1 in treatment-naïve HCV-Mono and HCV-Co without cirrhosis in a prospective registry of individuals receiving DAAs for HCV. Results Up to September 2017, a total of 17 269 patients were registered, and 1358 patients (1055 HCV-Mono/303 HCV-Co) met the inclusion criteria. Significant differences between HCV-Mono and HCV-Co were observed for age, gender, and G1 subtype distribution. Among HCV-Co, 99.0% were receiving antiretroviral therapy. SVR rates for LDV/SOF at 8 weeks did not differ significantly between HCV-Mono and HCV-Co (96.9% vs 94.0%; P = .199). However, the SVR rate for LDV/SOF at 12 weeks was significantly higher for HCV-Mono than HCV-Co (97.2% vs 91.8%; P = .001). A multivariable logistic regression model including age, sex, liver stiffness, G1 subtype, HCV-RNA, HIV, and treatment duration showed the factors associated with treatment failure to be male sex (adjusted odds ratio [aOR], 2.49; 95% confidence interval [CI], 1.27–4.91; P = .008) and HIV infection (aOR, 2.23; 95% CI, 1.13–4.38; P = .020). Conclusions The results of this large prospective study analyzing outcomes for LDV/SOF against HCV G1 in treatment-naïve noncirrhotic patients suggest that HIV infection is a predictor of treatment failure in patients with chronic hepatitis C.

Incident Cases

Early diagnosis and treatment of incident cases of hepatitis C virus (HCV) infection is fundamental to eliminate HCV in HIV-positive patients. From January 2016 to December 2019, we attended 40 episodes of acute HCV infection (AHC) in 35 subjects (9 reinfections) who were coinfected with HIV. The patients were treated with direct-acting antiviral agents (DAAs) in seven hospitals in Andalusia, Spain. All were men who have sex with men (MSM), mean age was 42.9 (±8.3) years and median time of HIV infection was 46.6 months (IQR: 20.4–67.2). All received antiretroviral therapy and had undetectable HIV viral load (except 2 with 65 and 68 copies/mL); median CD4 count was 632 cells/mm3 (IQR: 553–896). Over half (74.3%) also had another concomitant sexually transmitted infection, syphilis (48.6%) being the most common. AHC was asymptomatic in 32 cases (80%). Genotypeic distribution was G1a 65%, G4 32.5% and G1b 3%. Median time to DAA was 6 weeks (IQR: 4.3–18.3) and median baseline HCV RNA was 6.1 Log (IQR: 5.6–6.5). DAA regimens were SOF/LDV (19 episodes), SOF/VEL (14), ELB/GZV (5) and GLP/PIB (2). All presented sustained viral response and none discontinued due to adverse effects. In conclusion, early treatment with DAA in AHC patients proved effective and safe. It could be an excellent strategy to eliminate HCV infection in HIV-coinfected MSM.

Context.— Treatment of chronic viral hepatitis C (HCV) infection with direct-acting antiviral agents (DAAs) results in cure, or sustained viral response (SVR), in more than 90% of patients. However, there are subsets of patients who have persistent liver inflammation and fibrosis and develop hepatocellular carcinoma (HCC) despite achieving SVR. A possible reason for these phenomena may be the presence of virus particles in liver tissue but not blood, otherwise defined as occult infection. Objective.— To describe liver histologic findings following successful DAA therapy, test HCV RNA by (liver) tissue polymerase chain reaction in treated cases, and identify predictive markers for HCC development in treated cases. Design.— A total of 96 identified patients were divided into 4 groups, each differentiated by the presence or absence of SVR and HCC. Groups were compared for several clinicopathologic variables, including degree of inflammation and fibrosis, and the ‘directionality' of fibrosis in cirrhotic livers using the novel progressive-indeterminate-regressive scoring system. Results.— Overall, we found a significant decrease in inflammation in SVR patients. None of the patients showed regression of their cirrhosis following treatment. No evidence of occult HCV infection was seen in 40 livers tested, including 21 with HCC. The number of patients who developed HCC was similar in the SVR and non-SVR groups, and increased inflammation and fibrosis were associated with HCC development. Conclusions.— Following DAA-SVR there appears to be an overall decrease in inflammation, but the fibrosis tends to persist, at least in the short term (median follow-up of 20.2 months).

Purpose: Monitoring of hepatitis C virus (HCV) treatment response is performed by serial HCV RNA measurements; however, this may not be useful for predicting treatment success or failure with oral direct-acting antiviral agent (DAA) therapies. Liver enzyme levels, which are elevated in chronic HCV and tend to decline on therapy, may serve as a more logistically and economically feasible alternative for monitoring treatment response. Source: The Ottawa Hospital Viral Hepatitis Clinic patients (n=219), receiving interferon-free oral DAA treatments, were assessed for liver enzymes and HCV RNA levels at baseline, week 4 and ≥12 weeks post-treatment. Suppression cut points used for this analysis were ALT ≤ 40U L-1 and AST ≤ 30U L-1. The primary outcome was week 12 sustained virologic response (SVR). By our analysis, all indicators had strong PPV (>90%) but limited NPV (

Abstract Background Successful eradication of hepatitis C virus (HCV) has great impact on the prognosis of HCV-related complications and the associated mortality. The development of the new direct-acting antiviral drugs (DAAs) has revolutionized the treatment of HCV infection. HCV core antigen (HCVcAg) is a recently developed marker that displayed a good correlation with HCV RNA assays. Our main objectives were to correlate between serum levels of HCVcAg and HCV RNA loads in chronic HCV patients as well as to explore the potential value of HCVcAg assay in predicting treatment response to the new DAAs. The study enrolled a total of 280 chronic HCV-infected patients scheduled to start the new regimen for treatment of chronic HCV by all-oral, interferon-free DAAs. According to the viral load, the studied individuals were arranged into three groups corresponding to mild, moderate, and sever viremia. Serum level of HCVcAg was determined by ELISA technique and HCV RNA viral loads were quantified using the real-time PCR system. The assays were performed three times for all participants: prior to initiation of treatment, at the end of treatment (week 12), and 3 months post-treatment cessation (week 24). Results A statistically significant difference between HCV RNA and HCVcAg baseline levels among different viremia groups was detected (P < 0.001). There was a significant positive correlation between HCV RNA and HCVcAg baseline values among all the studied cases (P < 0.05) with a correlation coefficient of 0.752, 0.976, and 1.00 respectively for mild, moderate, and severe viremia groups. 92.9% (260/280) of the studied patients achieved sustained virologic response, 3.6% (10/280) were non-responders, and 3.6% (10/280) had recurrent viremia/relapse as regards RT-PCR results. Conclusion HCVcAg is a promising alternative to HCV RNA assay. The ELISAs for HCVcAg proved excellent correlations with HCV RNA levels. Moreover, HCVcAg can be introduced as a simple and highly specific tool for monitoring the new DAA regimens particularly in low-resource settings.

Abstract Background Hepatitis C virus (HCV) infection is a worldwide disease. HCV-related arthritis is one of the extrahepatic manifestations of the disease. The treatment of chronic HCV has been revolutionized with the introduction of oral direct-acting antiviral (DAA) drugs. We aim to determine the outcomes of treatment by the combination of sofosbuvir-daclatasvir with or without ribavirin in patients with HCV-related arthritis. Results Post-therapy, all group I patients had sustained viral response. Significant improvement of the outcome parameters was found 12 weeks post-treatment in group I compared to baseline and group II. Complete and partial remission of articular symptoms in group I patients was observed in 80% and 5%, respectively, while 85% of patients in group II showed no remission. Few mild side effects were encountered with therapy. Conclusion The combination of sofosbuvir-daclatasvir with or without ribavirin is an effective and safe therapy for eradication of HCV infection and amelioration of HCV-related arthritis.

Abstract Background In co-infected patients with hepatitis B (HBV) and hepatitis C (HCV), the treatment of HCV with direct-acting antiviral agents (DAA) can cause HBV reactivation. However, there are no clear guidelines on the timing of treatment initiation, especially in the absence of clinical signs of flare. Aims Here we discuss the case of a 34-year-old female with HBV and HCV genotype 3 who had HBV reactivation following HCV treatment, but did not require nucleos(t)ide therapy. Methods She initially presented with chronic inactive hepatitis B and chronic hepatitis C with HBV DNA level of 67.5 IU/mL and HCV RNA level of 3.33 x 106 IU/mL. She completed a 12 week course of sofosbuvir and velpatasvir for HCV and achieved sustained virologic remission, but subsequently developed reactivation of her HBV with HBV DNA peaking at 3.41 x 104 IU/mL twelve weeks post-treatment. She did not develop any signs of hepatitis and a decision was made to monitor her clinically. Results Two years later, she spontaneously went into remission with her HBV DNA levels being &lt;10 IU/mL. Conclusions The significance of this case is to illustrate HBV reactivation following treatment of HCV with DAAs may not necessitate immediate treatment, especially if there are no signs of flare. There have been similar reported cases, but larger prospective studies are required to determine the appropriate clinical context where monitoring may be acceptable instead of immediate treatment.

Abstract Background and aims Widespread use of direct-acting antiviral (DAA) agents to treat patients with hepatitis C virus (HCV) infection has reduced the need for monitoring of HCV-RNA levels, because viral kinetics do not predict sustained virologic response (SVR) to these drugs. However, the performance of cheaper tests, such as the assay to quantify HCV core antigen (HCV Ag), has not been determined. This study was aimed at investigating the accuracy of the HCV Ag test in predicting which patients receiving DAAs will achieve SVR at week 12 (SVR12). Methods We performed a prospective study on 90 patients, chronically infected with HCV, receiving DAAs therapy from different NCCVH centers in Cairo during the period from August 2017 to June 2018. We collected blood samples and measured the levels of HCV core Ag and HCV-RNA at baseline and 12 weeks after end of treatment. We compared the ability of these assays to predict which patients would have SVR12. Results The median baseline level of HCV-RNA was 1688529.6 ± 994697.3 IU/ml (range, 312700 IU/ml to 3491100 IU/ml) and HCV Ag was 179.2 ± 83.5 pg/ml (range, 33.5 pg/ml to 315.6 pg/ml). HCV Ag became undetectable in 92.2% 12 weeks after the end of treatment. HCV-RNA became undetectable in 87.8% at the end of treatment (P&lt;.0001). 79 out of 90 patients (87.8%) achieved an SVR12; the test for HCV Ag identified 63.6% of these patients. Conclusions Tests that measure HCV Ag monitor efficacy of DAA therapy for HCV infection as well as assays that measure HCV-RNA, and hence could be recommended for clinical practice.

Abstract: Hepatitis C virus infection causes approximately 4 million new infections worldwide, and 399 000 deaths due to its complications, cirrhosis and hepatocellular carcinoma (HCC). Microenvironmental changes, chronic inflammation, oxidative stress, endoplasmic reticulum stress caused by HCV infection, via genetic and epigenetic changes can result in primary liver cancer during decades. The direct oncogenic property of HCV is wellknown. The transforming effect of four HCV proteins (core, NS3, NS4B, NS5A) has been proven. Effective antiviral therapy, sustained viral response decreases the HCV-related general and liver-related mortality. Interferon-based therapy reduces the risk of HCC development. Shorter therapy with direct acting antiviral agents (DAA) has higher efficacy, fewer side-effects. Publications have reported the unexpected effects of DAA. The authors review the articles focusing on the occurrence of HCC in connection with DAA therapies. There is a need for prospective, multicentric studies with longer follow-up to examine the risk of HCC formation. After antiviral therapy, HCC surveillance is of high importance which means abdominal ultrasound every 3–6–12 months in sustained viral response patients as well. Orv Hetil. 2019; 160(22): 846–853.
