Evaluation Of A Strategy For Identification Of Hepatitis C Virus Carriers In Outpatient And Emergency Units: Contribution To The Microelimination Of Hepatitis C In Brazil
BRAZILIAN JOURNAL OF INFECTIOUS DISEASES(2021)
Abstract
Introduction: Hepatitis C virus (HCV) infection continues to be an important public health problem worldwide. Despite the availability of drugs that promote the cure of infection in more than 95% of cases, the identification of HCV carriers remains a major challenge. Objective: To evaluate a strategy for identifying HCV carriers based on combined criteria: screening in emergency units and specialty outpatient clinics of a tertiary hospital and among older adults (>= 45 years), both suggested as efficient in epidemiological studies. Methods: A cross-sectional, analytical and descriptive study was conducted on individuals of both sexes, aged 45 years and older, attending the emergency department and specialty outpatient clinics of a University Hospital in Sao Paulo, Brazil, from January 2016 to June 2018. After giving formal consent, the patients were submitted to a standardized interview and rapid testing for the identification of HCV antibodies (SD BIOLINE (R) anti-HCV). Results: A total of 606 adult patients (62% women and 37% men) were evaluated. The mean age was 62 +/- 10 years. Four positive tests were identified, with confirmation by conventional serology and HCV-RNA determination. Thus, the prevalence of HCV identified in the sample was 0.66%. All patients had a history of risk factors for infection. Conclusion: The strategies of birth-cohort testing and screening in emergency medical ser-vices for the identification of HCV carries, both suggested in the literature as efficient for the diagnosis of hepatitis C, resulted in a low rate of HCV infection. These findings highlight the magnitude of the challenge of identifying asymptomatic HCV carriers in Brazil.(c) 2021 Sociedade Brasileira de Infectologia. Published by Elsevier Espa na, S.L.U.
