The Impact

Background: Hepatitis C virus (HCV) infection is highly prevalent among patients on hemodialysis (HD) and is associated with poor prognosis. Treatment with interferon and ribavirin is poorly tolerated, and few data are available on the impact of new direct-acting antivirals (DAAs). This study was intended to analyze the efficacy and safety of treatment with a combination of ombitasvir/paritaprevir/ritonavir and dasabuvir with/without ribavirin in HCV-infected patients on HD from 3 hospitals. Methods: This is a multicentric study. We analyze the clinical course of all patients on HD with HCV infection who had been treated with the combination of ombitasvir/paritaprevir/ritonavir and dasabuvir in 3 hospitals in Madrid, Spain. All patients under treatment had undergone Transient elastography (FibroScan®) and HCV RNA (PCR) and HCV genotype were determined simultaneously. Results: Thirty-five patients aged 53.3 ± 8.9 years (68.6% males) and with genotypes 1 and 4 were treated with the DAA regimen, and 17 were also given ribavirin. The most common etiology was glomerular disease. Sustained viral response was achieved in 100% of patients. Adverse effects were negligible, and no patient had to discontinue treatment. The most significant side effect was anemia, which led to a significant increase in the dose of erythropoiesis-stimulating agents. Anemia was more marked in patients receiving ribavirin. No patients required transfusions. Conclusion: A combination of ombitasvir/paritaprevir/ritonavir and dasabuvir with/without ribavirin for the treatment of HCV in patients on HD is highly effective and causes minimal side effects. This regimen represents a major advance in disease management. A considerable improvement in prognosis seems likely.

e17556 Background: An association between Hepatitis C virus (HCV) infection and oropharyngeal cancers (OPCs) has been reported; however, the clinical significance of this epidemiological finding remains unknown. We therefore analyzed the oncologic outcomes of HCV-infected patients (pts) with OPCs. Methods: In this retrospective cohort study, all pts with OPCs seen at MD Anderson (1/2004-12/2015) were reviewed. HCV infection was defined as detectable HCV RNA in serum. Risk of 5-year (yr) overall survival (OS) and progression-free survival (PFS) was compared between HCV-infected (HCV+) and uninfected (HCV-) pts. OPCs that were positive for p16 by immunohistochemistry were considered HPV-related. Antiviral therapy (AVT) included either interferon (IFN)-based or IFN-free regimens. Multivariate cox proportional hazards model was used to identify independent predictors of mortality. Results: We studied 161 pts. Most of the pts were white (141; 88%), male (132; 82%) and had tumor stage 3 or 4 (147; 92%). The OPC involved tonsils (83; 52%), base of tongue (67; 42%) or soft palate (11; 7%). The median follow-up time after OPC diagnosis was 3 yrs (range: 1-13 yrs). HCV+ (n = 25) and HCV- pts (n = 136) were comparable in regards to smoking and alcohol status. In univariate analysis, HCV+ pts had more OPC progression after 1stline cancer treatment (48% vs 20.6% in HCV-, P = .0009) and were more likely to relapse (26% vs 5% in HCV-, P = .02). In multivariate analysis, HCV was associated with increased all-cause mortality [hazard ratio (HR): 2.15, 95% confidence intervals (CI): 1.08-6.85; P = .02] and risk of OPC progression [HR: 5.42, 95% CI: 2.64-11.14; P = .0008] independent of age and cirrhosis status. In HPV+ OPCs (n = 86), HCV + and HCV- pts did not have significant difference in mortality [HR: 2.03, 95% CI: 0.82-4.98; P = .12]. AVT was administered after OPC diagnosis in 8 of the 25 HCV+ pts (32%), with 6 of them receiving IFN-free AVT. HCV+ pts that received AVT had better 5 yr OS (median of 5.2 vs 2.3 yrs, P = .005) and PFS (median of 3.1 vs 0.7 yrs, P = .007) than the ones who did not. Conclusions: HCV seems to affect the oncologic outcomes of pts with OPCs and treating this infection might be beneficial. HCV screening and treatment should be considered in such pts.

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.

Viral Response

Background: Interferon-based antiviral therapies against hepatitis C virus (HCV) infection have been shown to reduce the incidence of hepatocellular carcinoma (HCC) in patients with sustained viral response (SVR). Recently, direct-acting antivirals (DAAs) have been proven to be much more effective in achieving SVR than interferon-based therapies. However, whether DAAs can efficiently prevent the occurrence of HCC after SVR remains controversial. To clarify this issue, we analyzed the clinical features of patients in whom HCC developed after achievement of SVR with DAAs for chronic HCV infection. Summary: Among patients who achieved SVR with daclatasvir and asunaprevir (n = 100), HCC developed in 17 patients (HCC group; n = 17) and did not develop in 83 patients (non-HCC group; n = 83) during a mean observation period of 15 months. A multivariate Cox proportional hazards analysis identified past history of HCC and male sex as significant risk factors for the emergence of HCC after DAAs. Sixteen cases with HCC after DAAs were in the very early or early stage (16/17, 94.1%), and one case was in the advanced stage (1/17, 5.9%) with portal venous tumor thrombus. Radiofrequency ablation and/or transarterial chemoembolization were performed in most cases as curative therapy (16/17, 94.1%). Key Messages: SVR by DAAs did not completely prevent the occurrence of HCC. However, even if HCC did develop after SVR, curative anticancer therapy was applicable in most cases.

Abstract Abstract 2934 Poster Board II-910 Background: hepatitis C virus (HCV) infection has been associated with increased risk of developing B-cell lymphoprolipherative disorders through chronic immune stimulation. Discordant data have been reported about the prevalence of HCV infection in patients with Waldenström's Macroglobulinemia (WM) and the putative role of HCV in lymphomagenesis of this non-Hodgkin Lymphoma subtype remains controversial. Aim: the current retrospective study was conducted to assess the impact of this infection itself in the clinical and biological features and outcome among WM patients as compared with those with HCV negative WM. Patients and methods: we analyzed 140 WM patients with tested anti-HCV antibody (HCV-Ab). HCV-Ab positivity was detected in 21 cases (15%). Clinical characteristics of patients at diagnosis of WM are reported in the table below. Results: HCV positivity was correlated to lower counts of platelets, neutrophil granulocytes, haemoglobin and with presence of cryoglobulins or autoantibodies and splenomegaly. Interestingly we even found a strong link between the presence of HCV and serum parameters of tumor burden such as beta-2 microglobulin (B2-M) and lactate dehydrogenase (LDH). Furthermore we did not reveal any outcome implications in terms of disease progression needing treatment, time from diagnosis to first therapy, overall survival between HCV- and HCV+ patients. Overall, 88 patients (63%) received treatment for disease progression with schedules including Rituximab in 46 cases (52% of treated patients). Rituximab was administered even in HCV-RNA positive patients associated to Cyclophosphamide and Fludarabine and this did not translate in hepatitis development. HCV-RNA was strictly monitored during immunotherapy and we did not observe any significant flair. Conclusions: in our series of patients HCV infection does not seem to affect clinical outcome of disease. Moreover, in our experience patients with documented infection can receive the same schedule of treatment including intensive chemotherapy even with monoclonal antibodies without development of further toxicity. Disclosures: No relevant conflicts of interest to declare.

Background & Aims: Smoking has multiple effects on factors influencing hepatitis C and antiviral therapy, including lipid metabolism, fibrosis, platelet count and adherence aspects. The aim of this analysis was to determine the impact of smoking on hepatitis C virus antiviral therapy. Methods: Data of two cohorts of an observational multicenter study including therapy-naïve patients infected with genotype 1 hepatitis C virus (HCV) treated with dual antiviral therapy (n=7,796) with pegylated interferon alpha 2a in combination with ribavirin, or triple antiviral therapy (n=1,122) containing telaprevir or boceprevir, were analysed. Results: In the univariate matched pair analysis of dual antiviral therapy patients (n=584), smoking was significantly associated with lower sustained viral response rates (p=0.026, OR 0.69 CI: 0.50 – 0.96). The effect of smoking on sustained viral response remained significant (p=0.028, OR 0.67 CI: 0.47 – 0.96) in the multivariate analysis when adjusting for all other baseline parameters with a significant association in the univariate analysis, i.e. diabetes, fibrosis, body mass index, transaminases and baseline viral load. Under protease inhibitors the influence of smoking on virological response did not arise. Conclusions: Smoking has a negative impact on antiviral therapy in naïve patients infected with HCV genotype 1 independently of age, gender, history of drug use or alcoholic liver disease. The effects of smoking might be overcome by the new antiviral agents.Abbreviations: APRI: AST to platelet ratio index; DAA: direct antiviral agent; DT: dual antiviral therapy; EoTR: end of treatment response; RVR: rapid virological response; EVR: early virological response; HCV: hepatitis C virus; IFN: interferon alpha; MPA: Matched Pair Analysis; NS: non-smokers; PEG-IFN: pegylated interferon alpha 2a; PI: protease inhibitor; RBV: ribavirin; SAE: serious adverse event; SOC: standard of care; S: smokers; SVR: sustained viral response.

Background: Prevalence of Hepatitis C viral infection and its major risk factors has been found out in population of Batkhela, Khyber Pakhtunkhwa, Pakistan by taking number of volunteers from the interested area. HCV prevalence has not been researched in recent time here in this area, so that’s why we contributed. Materials and Methods: Ab rapid test cassette serum/plasma (USA) kit has been used for the mentioned purpose following by ELISA and finally PCR to find out active infection of virus. ICT positive individuals were reconfirmed by ELISA and then ELISA positive samples were carefully investigated by RT-PCR for Hepatitis C Virus. Results: The study population was of 770 volunteers belonging to the mentioned area of research, 453 males and 317 females. The overall prevalence was found to be 5.32% of HCV in Batkhela. This prevalence ratio was 3.12% in males and 2.20 % in females. 3rd generation ELISA was used to refine ICT positive samples which showed that 37 of the ICT positive samples had antibodies detected by ELISA. To find out active HCV infection, ELISA positive samples were refined by real time PCR which showed 2.98% of prevalence of active HCV infection in Batkhela based on HCV RNA in their blood. Principle Conclusion: Overall prevalence was found 5.32%, contaminated reused syringes and blades at Barbour’s shop, blood transfusion, surgical operations and unhygienic food in stalls etc were found significant risk factors for acquiring HCV infection. Body weakness and pale yellow skin color was common symptom in HCV positive volunteers. Safe sexual activities, blood screening before donation and sterilizing surgical equipment’s can protect us from Hepatitis C Virus.

(1) Background: The World Health Organization adopted a strategy for the Global Health Sector on Viral Hepatitis in 2016, with the main objective of eliminating hepatitis C virus (HCV) by 2030. In this work, we aimed to evaluate the prevalence of HCV infection and risk factors in a Romanian village using population-based screening as part of the global C virus eradication program. (2) Methods: We conducted a prospective study from March 2019 to February 2020, based on a strategy as part of a project designed to educate, screen, treat and eliminate HCV infection in all adults in a village located in Northeastern Romania. (3) Results: In total, 3507 subjects were invited to be screened by rapid diagnostic orientation tests (RDOT). Overall, 2945 (84%) subjects were tested, out of whom 78 (2.64%) were found to have positive HCV antibodies and were scheduled for further evaluation in a tertiary center of gastroenterology/hepatology in order to be linked to care. In total, 66 (85%) subjects presented for evaluation and 55 (83%) had detectable HCV RNA. Of these, 54 (98%) completed antiviral treatment and 53 (99%) obtained a sustained virological response. (4) Conclusions: The elimination of hepatitis C worldwide has a higher chance of success if micro-elimination strategies based on mass screening are adopted.

Abstract Background Hepatitis C virus (HCV) is a leading cause of advanced liver disease and death. In the United States about 3.5 million people are living with HCV, but only 50% are aware of the infection, 16% are prescribed treatment, and only 9% achieve sustained viral response. The World Health Organization published an HCV elimination goal for 2030 that strives to achieve a 65% reduction in HCV-related deaths and 90% reduction in transmission. An important step toward this goal is micro-elimination at local hospitals by addressing care gaps in the HCV care cascade. Figure 1 Methods We created a retrospective cohort of patients who tested positive for HCV antibody (HCV Ab+) between 2016 and 2018 at Tufts Medical Center in Boston, Massachusetts. We assessed achievement of care cascade steps including HCV viral load (VL) testing, linkage to care, treatment initiation, and sustained viral response (SVR). We also assessed patient demographics, clinical factors and HCV risk factors. We used STATA/IC 14.1 to conduct bivariate analysis to identify factors associated with loss to follow-up across each care cascade step. Results A total of 24,308 HCV antibody tests were done during this timeframe, of which 5% (n=1,222) were HCV Ab+. After excluding duplicate tests, 1,041 unique patients with HCV Ab+ were included. This cohort had a mean age of 47 years and were 61% male, 66% white, 72% on public insurance, 12% HIV-positive, 13% HCV treatment-experienced. The most frequent HCV risk factor was injection drug use, occurring in 64% of patients. Of patients with HCV Ab+, 76% (n=791) were tested for an HCV VL, of which 50% (n=393) had detectable VL and 50% (n=398) had undetectable VL. Of the patients with a detectable VL, 58% (n=226) were linked with care. Following care linkage, 69% (n=155) initiated treatment, of which 90% (n=139) completed treatment, of which 97% (n=135) achieved SVR (Figure 1). Factors that were significantly associated with getting a VL test and linking to care included private insurance, HIV co-infection, absence of intravenous drug use and cirrhosis; however, these factors were not significantly associated with achieving subsequent steps. Conclusion Assessment of the HCV care cascade at our hospital allowed us to identify clear care gaps and areas needing improvement towards a local micro-elimination.
