Abstract Background Hepatitis C virus (HCV) is one of the major causes of chronic liver disease, cirrhosis, and liver cancer. Most of the infected people have no clinical symptoms. The current strategy for HCV elimination includes test and treatment. In this study, we aimed to evaluate the campaign for retrieving patients who were lost to follow-up, for subsequent re-evaluation. Methods From January 2020 to October 2020, patients who had prior tests for positive anti-HCV antibody in 2010–2018 in our hospital were enrolled for our patient callback campaign. Patients who had unknown HCV RNA status or no documented successful antiviral therapy history were selected for anti-HCV therapy re-evaluation. To facilitate patient referral in the hospital, we developed an electronic reminding system and called the candidate patients via telephone during the study period. Results Through the hospital electronic system, 3783 patients with positive anti-HCV antibody documentation were identified. Among them, 1446 (38.22%) had tested negative for HCV RNA or had anti-HCV therapy, thereby excluded. Of the 2337 eligible patients, 1472 (62.99%) were successfully contacted and called back during the study period for subsequent HCV RNA testing and therapy. We found that 42.19% of the patients had positive HCV RNA and 88% received subsequent anti-HCV therapy. Conclusions A significant number of patients with positive HCV serology were lost for HCV confirmatory test or therapy in the hospital. Therefore, this targeted HCV callback approach in the hospital is feasible and effective in achieving microelimination.

Background and Objectives: Co-infection of hepatitis C virus (HCV) with human immunodeficiency virus (HIV) is in- creasing due to similar transmission pathways. Chronic HCV infection is the most common complication among HIV-infect- ed individuals. Information on the frequency of HCV infection on Iranian HIV-infected individuals is scarce. The aim of this study was the detection of HCV prevalence and genotypes among HIV-infected people in Sanandaj, Iran. Materials and Methods: In this cross-sectional study, whole blood samples were taken from 185 HIV positive individuals referring to Consultation Center for Behavioral Diseases, Sanandaj, Iran. The ELISA test was done on samples for anti-HCV antibodies. RNA was extracted from only anti-HCV antibody positive samples. An RT-PCR test was conducted to detect HCV RNA. Genotypes of HCV were detected by melting curve analysis by specific primers and probes. Test results and demographic information were analyzed by SPSS software. Results: The mean age of individuals was 39.3 ± 9.4 years. Out of 185 individuals 99 (53.5%) were positive for anti-HCV antibodies. Out of 99 antibody positive individuals, 44 had HCV RNA. Among 44 RNA positive individuals, genotypes and subtypes of HCV were as 26 (59.1%) 1a, 17 (38.6%) 3a and one (2.2%) 4. There was a significant association between an- ti-HCV antibody and demographic variables including, age, gender, occupation, and CD4+ T-cell count (p = 0.0001). Conclusion: The present study reveals that HIV/HCV co-infection is high in the study population. It is recommended similar studies should be done in other HIV infected populations for management of HIV/HCV co-infection

Hepatitis C (HCV) infection could be spread by blood transfusion. Screening of HCV in donor blood could prevent HCV infection to the recipient. HCV antibody test using rapid test of multiple antibody detection by immunochromatography method is an easy and rapid test that could detect four HCV antibodies separately. The aim of this study was to evaluate the diagnostic value of antibody HCV using multiple antibody detection rapid test in diagnosing HCV infection. This was an analytical observational study with a cross sectional design. The samples consisted of 42 donors’ blood serum from the Surabaya Branch of the Indonesian Red Cross which underwent HCV infection test using ELISA method. The samples were then tested using PCR HCV RNA as the gold standard and antibody HCV multiple antibodydetection rapid test The diagnostic value of HCV antibody test using multiple antibody detection rapid test by immunochromatography method showed a diagnostic sensitivity of 100%, diagnostic specificity of 75%, positive predictive value of 66.7% and negative predictive value of 100%, a diagnostic efficiency of 83.3%, with a positive probability ratio of 4 times. The most often positive antibody pattern was four (4) positive antibodies (core protein, NS3, NS4 and NS5). Core protein (CP) and NS3 were the most often positive antibodies. Based on this study result, the HCV antibody test using multiple antibody detection rapid test by immunochromatography method has a good diagnostic value.

Abstract Background Between December 2018 and January of 2019, we evaluated the accuracy of the point-of-care Hepatitis C (HCV) antibody test (POC; OraQuick HCV) used at a community-based needle and syringe exchange program serving persons who inject drugs in Tallinn, Estonia. Methods We compared the results of screening for HCV antibodies by OraQuick (oral swab) and enzyme immunoassay (EIA; blood draw) and assessed test results implications in a high prevalence setting. Findings Of the 100 participants, 88 (88%) had reactive POC test results, and 93 were HCV antibody positive on EIA testing. Sensitivity, specificity and negative predictive value (NPV) for the POC assay with EIA as the relevant reference test were as follows: 94.6% (95% CI 90.0–99.2%), 100% and 58.3% (95% CI 30.4–86.2%). Of the 12 testing, HCV-negative with the POC only 7 (58.3%) were true negatives. Conclusions Oral swab rapid testing HCV screening in this nonclinical setting was sensitive and specific but had unacceptably low NPV. In high prevalence settings, POC tests with high sensitivity and that directly measure HCV RNA may be warranted.

Hepatitis C virus (HCV) infection can induce insulin resistance, and patients with diabetes mellitus (DM) have a higher prevalence of HCV infection. Patient outcomes improve after HCV eradication in DM patients. However, HCV micro-elimination targeting this population has not been approached. Little is known about using electronic alert systems for HCV screening among patients with DM in a hospital-based setting. We implemented an electronic reminder system for HCV antibody screening and RNA testing in outpatient departments among patients with DM. The screening rates and treatment rates at different departments before and after system implementation were compared. The results indicated that the total HCV screening rate increased from 49.3% (9505/19,272) to 78.2% (15,073/19,272), and the HCV-RNA testing rate increased from 73.4% to 94.2%. The anti-HCV antibody seropositive rate was 5.7%, and the HCV viremia rate was 62.7% in our patient population. The rate of positive anti-HCV antibodies and HCV viremia increased with patient age. This study demonstrates the feasibility and usefulness of an electronic alert system for HCV screening and treatment among DM patients in a hospital-based setting.

Background and objectives: Hepatitis C virus (HCV) is a major health problem in Egypt with its prevalence estimated to be 14.7% among general population in 2008. Patients receiving frequent blood transfusions like 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 study 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%) and rs12980275 AA/AG/GG were found in 8 (11.4%), 59 (84.3%) and 3 (4.3%).  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 high prevalence of HCV. Muti-transfused patients still exposed to a risk of transmission of HCV. IL28B gene polymorphisms are not associated with spontaneous clearance of HCV in this cohort of Egyptian children with SCD.

Background: Hepatitis C virus (HCV) genotypes and subtypes exhibit significant geographic variations.Aim: To analyse the distribution of genotypes/subtypes of HCV in a group of patients with chronic hepatitis C from Canton Sarajevo during 2012-2018.Material and methods:The study enrolled 247 human plasma samples of HCV-RNA positive patients with available results of HCV genotyping test.Results: During 2012-2018, the domination of subtypes 1a (34.01%), 1b (28.34%) and genotype 3 (23.89%) was registered. In 2012 and 2013, HCV subtype 1a was the most common (27/63; 42.86% and 17/40; 42.50%, respectively). In 2014, the leading HCV genotype/subtype were 3 and 1b (17/57; 29.82%). In 2015, the dominance of HCV genotype 3 (14/39; 35.90%) continued, while in 2016, the same number of HCV subtypes 1a and 1b (11/30; 36.67%) was recorded. Although in a small number of tested, during 2017, HCV subtype 1b was the most prevalent (7/14; 50.00%), and in 2018, it was replaced by a HCV subtype 1a (3/4; 75.00%). Distribution of HCV genotypes/subtypes by age group of patients varied significantly (p=0.000). The largest number of patients (71/247; 28.74%) belonged to the age category 30-39 years and HCV genotypes/subtypes 1, 3, 4, 1a and 1b were identified. Except in 2017, male gender significantly dominated (p=0.000). In males, HCV subtype 1a (68/170; 40.00%) was the most common, while in women it was HCV subtype 1b (44/77; 57.14%).Conclusion: This six-year retrospective study showed the time variations of the circulating HCV genotypes/subtypes among patients with chronic hepatitis C in Canton Sarajevo. Genotyping of the HCV has an important implications for diagnosis and treatment of the patients.

Abstract Background Despite hepatitis C virus (HCV) age cohort and risk factor screening recommendations, many at-risk individuals remain undiagnosed. Current screening practices may not adequately capture those at high risk for infection, especially in regions with increasing injection drug use (IDU). Universal HCV screening in a Tennessee tertiary care emergency department (ED) was introduced to help define regional epidemiology and to improve diagnosis and linkage to care. Methods This screening program was implemented in the Vanderbilt University Medical Center ED. Adult patients who underwent phlebotomy for clinical purposes were offered HCV screening. Samples were initially tested for HCV antibodies; if positive, samples were reflexed for HCV RNA testing. Patients with positive HCV RNA tests (i.e., active HCV infection) were notified, counseled, and offered linkage to care. Results A total of 11,637 screening tests were performed between April 1, 2017 and March 31, 2018, with 1,008 (8.7%) HCV antibody positive and 488 (4.2%) RNA positive. Of note, 81 (0.7%) were HCV antibody positive but RNA testing could not be performed due to insufficient sample volume. Several notable populations had high rates of HCV (Table 1). Importantly, 3.9% of people not born between 1945 and 1965 were HCV RNA positive, and they were the majority (63.5%) of patients with active HCV (Table 2). A minority (31.6%) of those with active HCV had a known history of IDU (Table 2). Conclusion HCV is common among patients presenting for emergency care at a Tennessee tertiary care ED. Universal screening identified many infections that would have been missed using age cohort and risk factors alone. ED HCV screening may be a useful method to augment guideline-based testing and intervene among populations not consistently screened. Disclosures C. A.

Lost To Follow Up

BackgroundThe Netherlands has a low hepatitis C virus (HCV) prevalence, estimated at 0.16%. Previous studies have shown that up to 30% of the diagnosed HCV population in the Netherlands has been lost to follow-up (LTFU). Retrieval of these patients could halt progression of liver disease in infected patients, reduce the number of infected individuals and limit HCV transmission. Several regional Dutch retrieval projects have already been executed, which demonstrated that retrieval is feasible. Therefore, we initiated a nationwide retrieval project, aiming to achieve microelimination in previously diagnosed but LTFU patients with chronic HCV through retrieval.MethodsLaboratory records will be used to identify possible patients with chronic hepatitis C, defined as either a positive most recent HCV RNA or positive HCV antibodies without known RNA result. Reviewing patient records and obtaining current contact information from municipality databases will identify LTFU patients who are eligible for retrieval. These patients will be invited for outpatient clinic care. The primary outcome of the study is the total number of LTFU patients who have been successfully linked to care.DiscussionHepatitis C ELimination In the NEtherlands (CELINE) is within the remit of WHO elimination targets and the Dutch National Hepatitis Plan. The methodology of CELINE is based on previously conducted regional retrieval projects and is designed to overcome some of their limitations. After ethical approval was obtained in 2018, the first centre initiated retrieval in 2018 and the project is expected to finish in 2021.Trial registration numberNCT04208035.

Abstract Background Liver fibrosis is an important risk factor for the development of hepatocellular carcinoma (HCC) after sustained virologic response (SVR) in patients with persistent hepatitis C virus (HCV) infection. However, as the degree of liver fibrosis changes following the eradication of HCV after SVR, it is unclear whether the prediction of HCC development based on liver fibrosis at baseline remains valid. Methods In 522 patients who achieved SVR by interferon-based anti-HCV therapy, the Fibrosis-4 Index for Liver Fibrosis (FIB-4 index) was updated annually by recalculation based on laboratory values after SVR. The incidence of HCC was reassessed annually based on the updated FIB-4 index. Results The percentage of patients with mild liver fibrosis (FIB-4 index <1.45) increased annually after SVR, whereas the percentage of patients with advanced liver fibrosis (FIB-4 index ≥3.25) decreased. The incidences of HCC based on the FIB-4 index remained constant between the time of SVR and subsequent annual updates. No patients developed HCC after SVR if the FIB-4 index decreased to <1.45. Conclusions The FIB-4 index retained its predictive ability for the risk of HCC when recalculated after SVR, despite the decrease in patients with high FIB-4 index values. Dynamic assessment of the FIB-4 index can be useful in the surveillance of HCC after SVR. Patients with a FIB-4 index <1.45 did not develop HCC even by the regression from advanced fibrosis after SVR. Further studies will be necessary to confirm these findings, which may result in a decrease in the number of patients in whom surveillance is required.
