STATUS OF HEPATITIS C VIRUS (HCV) INFECTION

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.

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.

Background: Pregnancy is a very crucial time in a woman’s life. In this period of time, not only multiple physiological alterations effect the usual health status but also makes women more vulnerable to contract infection and face negative sequalae. Hepatitis C, a blood borne viral infection serve the similar fate when encountered by pregnant ladies. This study is based on exploring the prevalence of the Hepatitis C virus seropositivity among pregnant population. Moreover, we also evaluated the major risk factors leading to the infection in these mothers. Besides this, infected mothers were studied for their pregnancy outcomes.Methods: In this study 114 pregnant females were observed for this cross-sectional study. It was conducted in Gynecology Unit- 1, Liaquat University Hospital Hyderabad, for the period of January 2017 to July 2017. Chi square test was applied for statistical analysis on SPSS version 16. The criteria for enrollment in the study was set to be a pregnant lady belonging to age group 20-35 years; having singleton pregnancy; was a booked case at the hospital with compliant to antenatal follow ups; admitted to the labor room for delivery. All the non-pregnant ladies, whom had co morbid conditions such as hypertension or diabetes or had infected with hepatitis B or D were excluded from the study. Furthermore, pregnant ladies with multiple gestion or those who were either diagnosed of hepatitis C prior to conceive or had a previous history of hepatitis C were also excluded.Results: Present study revealed that out of 114, 10(8.8%) pregnant ladies were found seropositive for Hepatitis C virus. Prior history for transfusion of blood was the Foremost risk factor discovered, with 60.5% women reported this. History of surgery was the 2nd commonest factor and 43.9% had this in their medical records. On the other hand, only 8.8% women gave the history for previous evacuation. While observing pregnancy outcomes, we found 48.2% neonates had low birth weight, 41.2% were born preterm and 21.1% had low APGAR score.Conclusions: In a nutshell hepatitis c is prevalent in the pregnant population of this region and showing its effects in the form of compromised pregnancies. History of blood transfusion and previous surgery were found to be chief risk factors in the study.

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.

Hcv Transmission

Hepatitis C virus (HCV) infection is an important global public health problem affecting approximately 180 million people. Multiple risk factors are associated with HCV transmission among haemodialysis (HD) patients leading to an increased risk for liver-related mortality. Patients undergoing HD may show a decreased humoral and cellular immunity, which lowers the sensitivity of the HCV antibodies (Abs) test resulting in false negative antibody test, thus requiring HCV RNA testing. Our study is to determine the prevalence of HCV markers (antibody RNA and genotype) and risk factors of HCV infection among patients in HD unit in Baghdad. A sample of 54 patients were interviewed. HCV Abs (anti-HCV) was tested using third generation enzyme immunoassay (EIA-3) and immunoblot assay (Lia-Tek III) as screening and confirmatory test respectively. Sera of 46 patients (irrespective to anti-HCV results) were subjected to molecular analysis, using the most developed RT-PCR and DNA Enzyme immunoassay (DEIA) method. Seropositive rate of anti-HCV and HCV-RNA were (66.6%) and (60.9%) respectively. Anti-HCV seropositive rate was significantly higher in males (77.1%), and history of blood transfusion (85%). Blood transfusion acts as a significant risk for acquiring HCV (OR 44.2, 95% CI 7.6-256.9). Genotype 4 was the most prevalent (33.3%), followed by genotype 1a (25.9%) and genotype 1b (22.2%). We concluded that, the prevalence of HCV among the haemodialysis patients is high. It is significantly related to gender, duration of dialysis and number of blood transfusion. Blood transfusion acts as a significant risk factor. Molecular test for detection for HCV RNA is necessary and proper nosocomial prevention program should be implemented to prevent HCV transmission.

Objective: Patients who frequently receive blood have high risk of hepatitis C virus (HCV) infection. This study aimed to evaluate the prevalence of HCV infection and potential risk factors among multiply transfused patients.Methods: A cross-sectional retrospective study was conducted in the hemophilia unit in Medical City in Baghdad, between June 1, 2016, and January 1, 2017. After taking consents and approval of ethical comity, the medical records of 1158 patients with hemophilia A and B, von Willebrand disease (vWD), thrombasthenia, Factors VII, X, and XIII deficiencies, and hypofibrinogenemia were analyzed for the presence of HCV antibody using (enzyme-linked immunosorbent assay). Cases of hemophilia were classified into mild, moderate, and severe.Results: The prevalence of HCV infection was 13.2%. Of total, 595 (51.4%) patients had hemophilia A and 99 (16.6%) were anti-HCV positive, while 225 (19.4%) had hemophilia B and 28 (12.4%) were antibody positive compared to 9 (7%) in vWD. Of those with hemophilia A, 515 (86.6%) had severe hemophilia, and 32 (32.32%) cases had acquired HCV infection after 1996 (after introduction of HCV screening in blood banks in Iraq). There was a statistically significant association with treatment by Factor VIII only.Conclusion: The prevalence of HCV in patients with inherited bleeding disorder is 13.2%. In this study, it was found that multitransfusion is the only predictor for HCV infection in this group of patients.

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.

AbstractIntroductionTo eliminate the hepatitis C virus (HCV) by 2030, Canada must adopt a micro-elimination approach targeting priority populations, including gay, bisexual, and other men who have sex with men (MSM). HCV prevalence and risk factors among MSM populations are context-dependent, and accurately describing these indicators at the local level is essential if we want to design appropriate, targeted prevention and treatment interventions. We aimed first to estimate and investigate temporal trends in HCV seroprevalence between 2005-2018 among Montréal MSM, and then to identify the socio-economic, behavioural, and biological factors associated with HCV exposure among this population.MethodsWe used data from three bio-behavioural cross-sectional surveys conducted among Montréal MSM in 2005 (n=1,795), 2009 (n=1,258), and 2018 (n=1,086). To ensure comparability of seroprevalence estimates across time, we standardized the 2005 and 2009 time-location samples to the 2018 respondent-driven sample. Time trends overall and stratified by HIV status, history of injection drug use (IDU), and age were examined. Modified Poisson regression analyses with generalized estimating equations were used to identify factors associated with HCV seropositivity pooling all surveys. We used multiple imputation by chained equations for all missing values.ResultsStandardized HCV seroprevalence among all MSM remained stable from 7% (95% confidence interval (CI): 3-10%) in 2005, to 8% (95%CI: 1-9%) in 2009, and 8% (95%CI: 4-11%) in 2018. This apparent stability hides diverging temporal trends in seroprevalence between age groups, with a decrease among MSM <30 years old, and an increase among MSM aged ≥45 years. History of IDU was the strongest predictor for HCV seropositivity (adjusted prevalence ratio: 8.0; 95%CI: 5.5-11.5), and no association was found between HCV seroprevalence and the sexual risk factors studied (condomless anal sex with men of serodiscordant/unknown HIV status, number of sexual partners, and group sex), nor with biological markers of syphilis.ConclusionsHCV seroprevalence remained stable among Montréal MSM between 2005-2018. Unlike other settings where HCV infection was strongly associated with sexual risk factors among MSM subgroups, IDU was the preeminent risk factor for HCV seropositivity. Understanding the intersection of IDU contexts, practices, and populations is essential to prevent HCV transmission among MSM.
