SUMMARYThe introduction of screening for hepatitis C virus (HCV) by the National Blood Transfusion Service identified donors who had acquired HCV infection. We undertook a case-control study amongst blood donors in the Trent Region to determine risks for HCV infection. A total of 74 blood donors confirmed positive for hepatitis C infection and 150 age, sex and donor venue matched controls were included in the study. Fifty-three percent of hepatitis C infected blood donors reported previous use of injected drugs compared to no controls; relative risk (RR) not estimatable (lower limit 95% CI = 20). Other risk factors were a history of: receipt of a blood transfusion or blood products RR = 3·6 (95% CI 1·5–8·3), having been a ‘health care worker’ RR = 2·8 (95% CI 1·1–7·6), tattooing RR = 3·3 (95% CI 1·2–8·7), and an association with having been born abroad RR = 3·2 (95% CI 1·1–9·5). No risk was shown for a history of multiple sexual partners, ear piercing or acupuncture. Injecting drug use explains more than 50% of hepatitis C infections in blood donors, a group who are less likely to have injected drugs than the general population.

Hepatitis C virus (HCV) infection has quite high prevalence in the prison system, reaching rates of up to 40%. This survey aimed to estimate the prevalence of HCV infection and evaluate risk factors for this exposure among male inmates at the Ribeirão Preto Prison, State of São Paulo, Brazil, between May and August 2003. A total of 333 participants were interviewed using a standardized questionnaire and underwent immunoenzymatic assaying to investigate anti-HCV. The prevalence of HCV infection among the inmates was 8.7% (95% CI: 5.7-11.7). The participants'mean age was 30.1 years, and the prevalence was predominantly among individuals over 30 years of age. Multivariate analysis showed that the variables that were independently associated with HCV infection were age > 30 years, tattooing, history of previous hepatitis, previous injection drug use and previous needle-sharing.

SUMMARYWe evaluated the occurrence of hepatitis C virus (HCV) infection in 97 former soccer players who played in Recife, Brazil in the 1960s and 1970s, and analysed the risk factors for infection, such as history of transfusions, surgery, tattoos, piercings, and the use of illicit drugs or injectable vitamin complexes. Immunochromatographic testing was performed to detect anti-HCV antibodies. All former soccer players were men (mean age 59·2 years), of whom 62 (64%) and 35 (36%) were classified as amateurs and professionals, respectively. Seven (7·2%) tested positive for anti-HCV antibodies; three (4·8%) were amateurs, and four (11·4%) were professionals. In univariate analysis, transfusion, surgery, and use of injectable vitamin complexes were associated with HCV infection, while in multivariate analysis, only the use of injectable vitamin complexes was related (P=0·0005). We observed a high frequency of HCV infection in former soccer players, especially in professionals who used injectable vitamin complexes.

Objective: To know the status of hepatitis C virus (HCV) infection in children admitted in Pediatric ward of Bahawal Victoria Hospital Bahawalpur. Study design: Cross-sectional descriptive study. Place and duration of study: Pediatric unit-1 Bahawal Victoria Hospital Bahawalpur over a period of 2 months and 15 days. Material and methods: This study was conducted over 500 children admitted in children ward-1 of Bahawal Victoria Hospital Bahawalpur. Children of 1-15 years of age were included in the study. The blood samples of these children were taken at the time of admission and serum was tested for HCV with ICT method and later on confirmed by ELISA. Children having HCV infection were tested for SGPT level. Different risk factors for transmission of HCV infection were also studied. Results: Out of 500 children 43 were HCV positive by ICT method. Out of these 43 ICT positive children 38 were confirmed by ELISA. In this way 7.6% children were found positive for HCV. In 23 cases (60.5%) SGPT was raised (>40). Statistically significant risk factors for transmission of HCV infection found in this study were past history of blood transfusion and history of injections in past. Conclusions: HCV infection is quite common in children. Safe blood transfusions and use of disposable and sterilized syringes is important for prevention of this infection.

Previous reports from the United States indicate that as many as 40% of patients with chronic hepatitis C virus (HCV) have no identifiable risk factor for HCV infection. To determine whether the same is true of Canadian patients with chronic HCV the records of 89 anti-HCV positive patients referred to the authors' tertiary care centre for evaluation of liver disease were reviewed. Each patient had been specifically asked about the following risk factors: previous blood transfusions; intravenous drug abuse; homosexual activity; sexual promiscuity (multiple sexual partners or a history of sexually transmitted diseases); tattoos made with nonsterile techniques; and ear piercing using nonsterile techniques. The results of the study revealed that 76 of 89 patients (85%) had at least one risk factor for HCV exposure, 38 (43%) had only one risk factor, 19 (21%) had two, 12 (14%) had three and the remaining three patients (3%) had four. The most common risk factor was a history of intravenous drug abuse (30 of 89 patients, 34%) followed by sexual promiscuity (28, 32%), previous blood transfusions (21, 24%), tattoos (17, 19%), homosexual contacts (seven, 8%) and ear piercing (five, 6%). Contrary to a recent report identifying sexual contact as an independent risk factor for HCV infection, only four cases (5%) were found where sexual promiscuity was identified as the only risk factor. In conclusion, these findings indicate that a possible source of HCV infection can be identified in a large majority of Canadians referred to an urban centre with chronic HCV infection.

BACKGROUNDThe natural history of hepatitis C virus (HCV) infection is variable and factors determining the course of the illness are unclear. AIMSTo determine the natural course of HCV infection in a well characterised group of patients 18 years after an epidemic outbreak of non-A, non-B hepatitis at a plasmapheresis centre.METHODSBetween 1994 and 1996, 20 of 30 affected individuals were studied. HCV infection was confirmed using second and third generation ELISA test kits. HCV RNA was detected by a polymerase chain reaction (PCR) method and HCV genotyping was performed by analysing amplicons from the conserved 5′-non-translated region generated by nested PCR. Thirty two liver biopsies were carried out in 14 patients.RESULTSHCV antibodies were detected in all subjects. Eighteen patients had abnormal liver enzymes and 17 were HCV RNA positive, all of whom were infected with genotype 1a. Ninety per cent of this cohort showed evidence of chronic HCV infection with 50% having progressive liver disease and 20% cirrhosis 18 years after acute onset of non-A, non-B hepatitis. Considerable variation in disease outcome occurred between individuals and no correlation with clinical features of the acute illness was found.CONCLUSIONSVariability in the consequences of HCV infection in cases infected with the same virus suggests that host factors are important in determining disease outcome. The factors which determine differences in the natural history of the disease still remain to be elucidated.

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.
