Background: Increased incidence of HCV infection is noted universally throughout the world in patients undergoing haemodialysis. Genotyping and gene sequencing of Hepatitis C virus in individuals with positive HCV-RNA helps in determining the optimal type, duration and response to therapy. Aim of the study was to determine gene sequencing which is considered as gold standard for determination of genotypes.Methods: A cross sectional study design was conducted among 250 patients from five dialysis centres in Pune city in a period of one year. Qualitative HCV RNA detection was carried out by nested RT-PCR. Genotyping and sequencing was carried out using the Big-Dye Terminator cycle sequencing ready reaction kit. SPSS 21.0 version software was used to analyze the data.Results: Out of total 250 patients 47(18.8%) were anti HCV antibody positive and 37 (14.8%) were HCV RNA positive. Out of 47 patients who tested positive for anti-HCV antibody 36 showed presence of HCV RNA (76.6% positive correlation). Out of 203 ELISA negative patients only 1 was found to be positive. Out of total 37 patients predominant genotype was found to be 1a (54.1%) followed by 1b (43.2%) and 3a (2.7%).Conclusions: Genotyping and gene sequencing in patients with HCV RNA positivity revealed predominant genotype 1a and 1b. Detailed phylogenetic tree analysis revealed clustering of same genotypes in centre likely suggesting common source of infection prevalent in dialysis units and nosocomial transmission of virus.

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.

Background: To study the prevalence of hepatitis-C virus infection in multi-transfused thalassemic children and to correlate these patients with age, number of transfusion, serum ferritin levels and transaminases levels.Methods: This study was conducted in the Department of Pediatrics of a Teaching Institute of Rajasthan. It was a hospital based cross sectional study, conducted over a period of 12 months (April 2016- March 2017). Blood sample for Ant-HCV antibody detection was taken at time of follow-up visit in the subspeciality clinic. These samples were processed in central laboratory for hep-C antibody, serum ferritin and transaminases levels. Anti-HCV antibody detection was done by BI-DOT machine. HCV RNA PCR was done to access viral load in all positive cases.Results: A total of 300 patients were enrolled in the study. There were 219 (73%) males and 81 (27%) females. The mean age of the study group was 7.59±3.6 years (range 1.5-18years). At the time of our study 277 (92.4%) cases were on one or the other chelating agent whereas 23 (7.6%) cases were not taking any kind of chelation therapy. Out of 300 patients, 72(24%) cases tested positive for anti HCV antibody. Out of 72 patients only 36(12%) patients had detectable viral load in RNA PCR.  Mean age of the HCV positive cases (9.58±3.28) years was higher as compared to HCV negative cases (6.98±3.54). Maximum HCV positivity 20/38 (52.6%) was seen in 12-18 year age group; followed by 33/76 (43.4%) in 9-12yr age group. Significant association was observed between advancing age and prevalence of hepatitis C in thalassemia major patients (p=0.002). The number of blood transfusions received by anti-HCV positive children (Avg. Transfusion 185±98.40 ml/kg/year) was significantly higher than that by anti-HCV negative patients (Avg. Transfusion 102.8±71.20) (p value<0.001). Maximum HCV positive cases 33 (45.83%) had total transfusions >200 in a year followed by 15 (20.83%) cases with 151-200 transfusions (p<0.001).Conclusions: Despite ELISA screening of blood donors, our study demonstrated high (24%) prevalence of transfusion transmitted hepatitis-C virus in thalassemic children which increases with increasing number of transfusions, it also correlates with rising serum ferritin level and SGPT level.

Background and objectives- Hepatitis C virus (HCV) infection is a major cause of chronic liver disease worldwide, with majority of the patients being asymptomatic and when they present to clinicians, they have already advanced liver disease in form of cirrhosis or hepatocellular carcinoma. Data from developing countries on this evolving global health problem are sparse. Hence this study was planned with the aim to determine the HCV genotypes prevalant in patients attending a tertiary care hospital with their clinical prole. Materials and Methods- Detailed history taking and clinical examination were done of consecutive 30 patients who attended out-patient department or admitted at in- patient department of Tropical Medicine with chronic hepatitis C. Laboratory investigations like LFT, viral serology (HBsAg, AntiHCV, HIV), prothrombin time, ultrasonography of upper abdomen, HCV- RNA Quantative assay with genotyping were done. Data were collected and then analysed using standard statistical methods. Result- Of proposed 30 sample size, complete data could be collected of 28 patients and accordingly, analysis was done. Of the 28 HCV seroreactive individuals, majority (20) were males. The mode of transmission was unknown in 19 patients, blood transfusion in 5 patients who were thalassemic and hemodialysis in remaining 4 patients. Most of the patients (18/28) were asymptomatic even if their viral load was high. Most common presenting symptom was dyspepsia. LFT showed signicant transaminitis in 50% of the patients. Of the 28 seroreactive patients, 15 (53.57%) were HCV RNA positive based on RT-PCR. HCV rNA was below detectable level in 13 patients. HCV genotype 3 was the predominant genotype found in 11 individuals followed by genotype 1 found in 3 and genotype 2 was seen in one individual. Conclusion- Community screening specially among high risk individuals is needed for early diagnosis and prompt treatment of chronic hepatitis C to prevent its several complications and also to prevent community spread.

Abstract Hepatitis C virus (HCV) is a major cause of transfusion-induced chronic liver disease in hemophiliacs, with 70% to 90% being anti-HCV positive. Seroreversion or loss of antibody response to HCV has been observed in a small proportion of human immunodeficiency virus-positive [HIV(+)] anti-HCV(+) hemophilic men. Despite the seroreversion to an anti-HCV- negative state, such patients continue to show serum alanine aminotransferase (ALT) elevations and biopsy evidence of cirrhosis and/or chronic active hepatitis. To determine the cause for the loss of anti-HCV antibody, we compared first- and second-generation anti-HCV enzyme immunosorbent assay (EIA 1.0 and 2.0), second-generation recombinant immunoblot (RIBA 2.0), and HCV-RNA amplification using polymerase chain reaction (PCR) in 19 “seroreverters” before and after seroreversion. There was no difference between 19 seroreverters and 59 persistently anti-HCV-positive hemophiliacs in mean ALT (1.1 +/- 0.1 XUL v 2.0 +/- 0.2 XUL; chi 2 = 1.80, P > .05), in mean CD4 (188 +/- 36/microL v 232 +/- 28/microL; t = 0.965, P > .05), or in the rate of progression to acquired immunodeficiency syndrome (13 of 19 [68.4%] v 30 of 59 [50.9%]; chi 2 = .987, P > .05, respectively). Before seroreversion, all 19 seroreverters (100%) were positive for EIA 1.0 and 2.0 and PCR, and all but 2 of 19 (89.5%) were RIBA 2.0 positive, whereas, after seroreversion, none were positive for EIA 1.0, 15 of 19 (78.9%) were positive for EIA 2.0, 8 of 18 (44.4%) were positive for RIBA 2.0, and 18 of 19 (94.7%) were positive for PCR. There was a lower CD4 lymphocyte number after seroreversion in those who were RIBA 2.0 negative as compared with those who were RIBA 2.0 positive (32 +/- 10/microL v 171 +/- 52/microL; t = 2.638, P > .05). These results indicate that HIV(+) anti-HCV(+) hemophilic men who undergo “HCV seroreversion” are truly infectious and anti-HCV positive by second- generation tests. Anti-HCV detection in immunosuppressed hosts is significantly improved by second-generation EIA and RIBA assays.

Previous work on hepatitis C virus (HCV) led to the discovery of a new form of virus particle associating virus and lipoprotein elements. These hybrid particles (LVP for lipo-viro-particles) are enriched in triglycerides and contain at least apolipoprotein B (apoB), HCV RNA and core protein. These findings suggest that LVP synthesis could occur in liver and intestine, the two main organs specialized in the production of apoB-containing lipoprotein. To identify the site of LVP production, the genetic diversity and phylogenetic relationship of HCV quasispecies from purified LVP, whole serum and liver biopsies from chronically infected patients were studied. HCV quasispecies from LVP and liver differed significantly, suggesting that LVP were not predominantly synthesized in the liver but might also originate in the intestine. The authors therefore searched for the presence of HCV in the small intestine. Paraffin-embedded intestinal biopsies from 10 chronically HCV-infected patients and from 12 HCV RNA-negative controls (10 anti-HCV antibody-negative and two anti-HCV antibody-positive patients) were tested for HCV protein expression. HCV NS3 and NS5A proteins were stained in small intestine epithelial cells in four of the 10 chronically infected patients, and not in controls. Cells expressing HCV proteins were apoB-producing enterocytes but not mucus-secreting cells. These data indicate that the small intestine can be infected by HCV, and identify this organ as a potential reservoir and replication site. This further emphasizes the interaction between lipoprotein metabolism and HCV, and offers new insights into hepatitis C infection and pathophysiology.

Abstract Background We implemented and evaluated a large health system-wide hepatitis C virus (HCV) screening and linkage to care program for persons born between 1945 and 1965 (“baby boomers”). Methods An electronic health record (EHR) clinical decision support (CDS) tool for HCV screening for baby boomers was introduced in August 2015 for patients seen in the outpatient University of California, Los Angeles healthcare system setting. An HCV care coordinator was introduced in January 2016 to facilitate linkage to HCV care. We compared HCV testing in the year prior (August 2014–July 2015) to the year after (August 2015–July 2016) implementation of the CDS tool. Among patients with reactive HCV antibody testing, we compared outcomes related to the care cascade including HCV ribonucleic acid (RNA) testing, HCV RNA positivity, and linkage to HCV specialty care. Results During the study period, 19606 participants were screened for HCV antibody. Hepatitis C virus antibody screening increased 145% (from 5676 patients tested to 13930 tested) after introduction of the CDS intervention. Screening increased across all demographic groups including age, sex, and race/ethnicity, with the greatest increases among those in the older age groups. The addition of an HCV care coordinator increased follow-up HCV RNA testing for HCV antibody positive patients from 83% to 95%. Ninety-four percent of HCV RNA positive patients were linked to care postimplementation. Conclusions Introduction of an EHR CDS tool and care coordination markedly increased the number of baby boomers screened for HCV, rates of follow-up HCV RNA testing, and linkage to specialty HCV care for patients with chronic HCV infection.

Background and Objectives: Hepatitis C is the most common hepatotropic viral infection that affects patients on mainte- nance hemodialysis. Most of the laboratories in India depend on HCV antibody detection by ELISA. PCR based studies on detection of HCV RNA among haemodialysis patients are very scanty in India. The current study was undertaken to find the prevalence of HCV among haemodialysis patients by ELISA and PCR. Materials and Methods: This prospective study was conducted from January to May 2018 in a total of 100 samples. Patients more than 18 years of age, who had undergone at least 15 sessions of dialysis were enrolled in the study. All samples were screened for HCV antibody by ELISA and HCV RNA by PCR. Data regarding age and gender of the patients, history of blood transfusion, duration of hemodialysis, total bilirubin levels were collected from medical records. Results: Among the 100 samples, only one was positive for HCV antibody by ELISA. Eight samples were positive for HCV RNA by PCR. In this study 62.5% of the HCV positives had a previous history of blood transfusion. Duration of dialysis was more among the HCV positive group but there was no statistical significance. Conclusion: This is the first study from the southern state of Kerala in India showing the prevalence of HCV among hemo- dialysis patients by PCR. Our study showed an overall HCV prevalence of 8% by PCR. All the PCR positive samples were negative by 3rd generation ELISA which is an alarming finding and further justifies the need for PCR for detecting HCV.

Abstract Background Hepatitis C virus (HCV) infection is highly prevalent among people who inject drugs (PWID). Accurate data on HCV prevalence and incidence rates among patients receiving opioid substitution treatment (OST) are needed to estimate the current and future burden of HCV infections in this high-risk population. Methods Baseline data from routine care were collected between October 2014 and June 2016 from randomly selected OST facilities in Germany. The primary outcome measure was the HCV status (antibody and RNA prevalence). Patients who were HCV antibody–negative at baseline were followed up after 12 months to calculate the HCV incidence rate. Results Sixty-three facilities from 14 German Federal States provided clinical data for a total of 2466 OST patients. HCV antibody and HCV RNA prevalence were 58.8% (95% confidence interval [CI], 56.8%–60.8%) and 27.3% (95% CI, 25.5%–29.2%), respectively. At baseline, a total of 528 patients (21.4%) had previously undergone antiviral treatment. Moreover, lower HCV RNA prevalence was associated with female gender, employment, younger age, and shorter duration of OST and opioid dependence. The HCV incidence rate was 2.5 cases per 100 person-years. Conclusions The low HCV RNA prevalence and HCV incidence rates confirm that OST in Germany is an effective setting both for treating chronic HCV infections and for preventing new infections among PWID. Scaling up the provision of OST, HCV testing, and HCV treatment among OST patients are important public health strategies for reducing HCV infections in this high-risk population.

Abstract Background As a blood-borne pathogen, hepatitis C virus (HCV) has long been a major threat associated with needle-stick injuries (NSIs) mainly because no vaccine is available for HCV. Following an NSI, we usually test the source patient for HCV antibody (HCV-Ab). Since HCV-Ab positivity does not necessarily indicate current infection, HCV RNA is further examined in patients positive for HCV-Ab. Direct-acting antivirals (DAAs) have enabled us to treat most HCV-infected patients; therefore, we speculate that the rate of HCV RNA positivity among HCV-Ab-positive patients decreased after the emergence of DAAs. This cross-sectional study was performed to investigate the change in the actual HCV RNA positivity rate in source patients before and after the interferon (IFN)-free DAA era. Methods This was a cross-sectional study of NSI source patients at a tertiary academic hospital in Japan from 2009 to 2019. IFN-free DAA regimens were first introduced in Japan in 2014. Accordingly, we compared HCV status of NSI source patients that occurred between 2009 and 2014 (the era before IFN-free DAAs) with those that occurred between 2015 and 2019 (the era of IFN-free DAAs) in a tertiary care hospital in Japan. Results In total, 1435 NSIs occurred, and 150 HCV-Ab-positive patients were analyzed. The proportion of HCV RNA-positive patients significantly changed from 2009 through 2019 (p = 0.005, Cochran–Armitage test). Between 2009 and 2014, 102 source patients were HCV-Ab-positive, 78 of whom were also positive for HCV RNA (76.5%; 95%CI, 67.4–83.6%). Between 2015 and 2019, 48 patients were HCV-Ab-positive, 23 of whom were also positive for HCV RNA (47.9%; 95%CI, 34.5–61.7%; p = 0.0007 compared with 2009–2014). In the era of IFN-free DAAs, 9 of 23 HCV RNA-negative patients (39.1%) and 2 of 22 HCV RNA-positive patients (9.1%) were treated with an IFN-free combination of DAAs (p = 0.0351). Regarding the departments where NSIs occurred, HCV RNA-negative patients were predominant in departments not related to liver diseases in the era of IFN-free DAAs (p = 0.0078, compared with 2009–2014). Conclusions Actual HCV RNA positivity in source patients of NSIs decreased after the emergence of IFN-free DAAs. IFN-free DAAs might have contributed to this reduction, and HCV RNA-negative patients were predominant in departments not related to liver diseases in the era of IFN-free DAAs.
