The emergence of hepatitis C virus (HCV) and its associated sequelae in Africa is a cause for significant concern. Human immunodeficiency virus (HIV) positive patients are at an increased risk of contracting HCV infection due to similar risk factors and modes of transmission. We investigated the seroprevalence of hepatitis C in hospitalized HIV-positive and HIV-negative patients in Mulago Hospital, an academic hospital in Uganda. Blood samples were first tested for HCV antibodies, and positive tests were confirmed with HCV RNA PCR. We enrolled five hundred patients, half HIV-positive and half HIV negative. Overall, 13/500 patients (2.6%) tested positive for HCV antibodies. There was no difference in HCV antibody detection among HIV-positive and HIV-negative patients. Out of all risk factors examined, only an age greater than 50 years was associated with HCV infection. Traditional risk factors for concurrent HIV and HCV transmission, such as intravenous drug use, were exceedingly rare in Uganda. Only 3 of 13 patients with detectable HCV antibodies were confirmed by HCV RNA detection. This result concurs with recent studies noting poor performance of HCV antibody testing when using African sera. These tests should be validated in the local population before implementation.

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.

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

SUMMARYWe studied hepatitis C virus (HCV) prevalence and risk factors for HCV infection in a sample of Brazilian HIV-positive patients. A cross-sectional study was conducted with 580 HIV-positive patients from a specialized HIV/AIDS diagnosis and treatment centre in southern Brazil. All patients were interviewed for socio-demographic and risk factors and tested for HCV antibodies and HCV-RNA detection. A multivariate analysis was performed to identify risk factors for HCV infection. A total of 138 (24%) patients had past or chronic hepatitis C. The following risk factors were associated with HCV infection for each gender: alcohol misuse and injecting drug use in women (P < 0·001) and low educational level, smoking drug use, and injecting drug use in men (P < 0·01). These results suggest that alcohol misuse, low educational level, smoking drug use, and injecting drug use are probable risk factors for HCV infection in HIV-positive patients. This information contributes to an understanding of the epidemiology of HIV/HCV co-infection in Brazil.

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.

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.

ABSTRACT Hepatitis C virus (HCV) chronically infects approximately 170 million people worldwide, with an increased risk of developing cirrhosis and hepatocellular carcinoma. The study of HCV replication and pathogenesis has been hampered by the lack of an efficient stable cell culture system and small-animal models of HCV infection and propagation. In an effort to develop a robust HCV infection system, we constructed stable human hepatoma cell lines that contain a chromosomally integrated genotype 2a HCV cDNA and constitutively produce infectious virus. Transcriptional expression of the full-length HCV RNA genome is under the control of a cellular Pol II polymerase promoter at the 5′ end and a hepatitis delta virus ribozyme at the 3′ end. The resulting HCV RNA was expressed and replicated efficiently, as shown by the presence of high levels of HCV proteins as well as both positive- and negative-strand RNAs in the stable Huh7 cell lines. Stable cell lines robustly produce HCV virions with up to 108 copies of HCV viral RNA per milliliter (ml) of the culture medium. Subsequent infection of naïve Huh7.5 cells with HCV released from the stable cell lines resulted in high levels of HCV proteins and RNAs. Additionally, HCV infection was inhibited by monoclonal antibodies specific to CD81 and the HCV envelope glycoproteins E1 and E2, and HCV replication was suppressed by alpha interferon. Collectively, these results demonstrate the establishment of a stable HCV culture system that robustly produces infectious virus, which will allow the study of each aspect of the entire HCV life cycle.

Objectives: Screening for hepatitis C virus (HCV) infection in jail provides an opportunity to educate and offer care to a high-risk population. We aimed to (1) estimate the prevalence of HCV infection in jail; (2) describe the demographic characteristics, risk factors, and pre-incarceration health insurance status associated with HCV infection; and (3) examine the implementation of HCV screening in jail. Methods: We conducted a retrospective analysis of an opt-out HCV screening program with HCV RNA confirmation and patient education at the Dallas County Jail from April 1 through November 2, 2017. We extracted data on test results, demographic characteristics, and release destination from electronic medical records. A nurse navigator recorded data on patient self-reported risk factors and pre-incarceration health insurance status. Results: Of 4089 incarcerated persons screened, 708 (17.3%) had a positive HCV antibody result. Of these, 641 (90.5%) had an HCV RNA test ordered; 576 (89.9%) had RNA tests completed, of whom 413 (71.7%) had a positive HCV RNA result. Of these 413, 352 (85.2%) received patient education. Half of HCV RNA-positive incarcerated persons (n = 207, 50.1%) were born outside the birth cohort (1945-1965). Among those with HCV infection, commonly reported risk factors were injection drug use (168 of 352; 47.8%) and tattoos (82 of 352; 23.4%). Most incarcerated persons with HCV infection (284 of 350; 81.1%) did not have health insurance. HCV antibody prevalence was higher among incarcerated persons released to prison (232 of 961; 24.1%) than to outside agencies (38 of 403; 9.4%) or the community (178 of 1026; 17.4%). Conclusions: Screening for HCV with RNA confirmation in jail provides an opportunity for disease education, transmission prevention, and navigation to HCV treatment. Future efforts should examine post-incarceration linkage to care.

Abstract Infection with hepatitis C virus (HCV) has previously been associated with the pathogenesis of low grade B-cell lymphoproliferative diseases including Waldenstrom’s macroglobulinemia (WM). Most of these studies have utilized HCV antibody detection assays, which may not accurately assess HCV presence in patients with impaired humoral responses. In patients with WM, pronounced IgA and IgG hypogammaglobulinemia is present, which remains persistant despite therapy (Blood 104:306b). As such, we investigated the incidence of HCV in 88 randomly selected, and previously untreated patients with the consensus panel diagnosis of WM utilizing both HCV antibody detection and qualitative PCR assays (Quest Diagnostics, Cambridge, MA, USA). The median age for these patients was 61 (38 – 83 years) and the male: female sex ratio was 1.44. No patient had a known history of liver disease, hepatitis B, HCV or HIV infection. Liver function tests obtained at time of serum collection showed normal range SGOT and and SGPT levels for 86/88 patients. In contrast to previous reports, we failed to demonstrate HCV infection by both HCV antibody detection and the PCR assays. These studies therefore show no association of WM with HCV infection.
