Prevalence of Hepatitis C Virus in Brazil's Inmate Population: A Systematic Review

OBJECTIVE
To estimate the prevalence of hepatitis C virus infection in Brazil's inmate population.

METHODS
Systematic review on hepatitis C virus infection in the inmate population. Brazilian studies published from January 1, 1989 to February 20, 2014 were evaluated. The methodological quality of the studies was assessed using a scale of 0 to 8 points.

RESULTS
Eleven eligible studies were analyzed and provided data on hepatitis C virus infection among 4,375 inmates from seven states of Brazil, with a mean quality classification of 7.4. The overall hepatitis C virus prevalence among Brazilian inmates was 13.6% (ranging from 1.0% to 41.0%, depending on the study). The chances of inmates being seropositive for hepatitis C virus in the states of Minas Gerais (MG), Sergipe (SE), Mato Grosso do Sul (MS), Rio Grande do Sul (RS), Goiás (GO) and Espirito Santo (ES) were 84.0% (95%CI 0.06;0.45), 92.0% (95%CI 0.04;0.13), 88.0% (95%CI 0.09;0.18), 74.0% (95%CI 0.16;0.42), 84.0% (95%CI 0.08;0.31) and 89.0% (95%CI 0.01;0.05) respectively, lower than that observed in the Sao Paulo state (seroprevalence of 29.3%). The four studies conducted in the city of Sao Paulo revealed a lower prevalence in more recent studies compared to older ones.

CONCLUSIONS
The highest prevalence of hepatitis C virus infection in Brazil's inmate population was found in Sao Paulo, which may reflect the urban diversity of the country. Despite Brazilian studies having good methodological quality to evaluate the prevalence of the hepatitis C virus, they are scarce and lack data on risk factors associated with this infection, which could support decisions on prevention and implementation of public health policies for Brazilian prisons.

High-Impact Hepatitis C Virus Testing for Injection Drug Users in an Urban ED

OBJECTIVES:
We implemented the "High-Impact Testing for Injection Drug Users", or the "HIT IDU" initiative, an emergency physician (EP)-based hepatitis C virus (HCV) testing program. The objective of this study was to evaluate the outcomes of this clinical protocol.

METHODS:
This was a prospective observational pilot study. The HIT IDU initiative encouraged EPs to integrate targeted HCV testing into care, with an emphasis on screening all people who inject drugs (PWID). Physicians selected the primary indication for HCV testing from a drop-down menu integrated into the electronic ordering process. The primary outcome was the absolute number and overall proportion of EP-based HCV antibody positive tests, further stratified by the indication for testing.

RESULTS:
Over the 3-month study period, 14,253 unique patients were evaluated, and EPs tested 155 patients for HCV (1.1%; 95% confidence interval [CI], 0.9%-1.2%), of which 40 (26%, 95% CI, 19%-33%) were HCV antibody positive. The proportion of HCV antibody positivity by testing indication was as follows: PWID 47% (34/73; 95% CI, 35%-59%), patient requested test 10% (4/40; 95% CI, 3%-24%), confirm patient report 67% (2/3; 95% CI, 9%-99%), liver disease of uncertain etiology 0% (0/3; 95% CI, 0%-71%), and other 0% (0/36; 95% CI, 0%-10%). There were 22 patients chronically infected, 19 had a follow-up appointment arranged, 3 attended their follow-up appointment, and 1 patient was treated at 1 year of follow-up.

CONCLUSIONS:
Although the overall number of EP-based HCV tests performed was low, high rates of infection were identified, particularly among PWID. There were significant challenges with linkage to care.

Seroprevalence of HCV Markers among HIV Infected Patients from Curitiba & Metropolitan Region, Brazil

OBJECTIVE:
to determine the prevalence and epidemiological factors associated with hepatitis (HCV) coinfection in human immunodeficiency virus (HIV) patients from Curitiba and the metropolitan region.

METHODS:
a study with 303 HIV+ patients, mean age 41.2 years (18-73); 50.5% men, followed at the Hospital de Clínicas, Universidade Federal do Paraná, between April 2008 and March 2009. Clinical and epidemiological data were obtained through questionnaires and retrospective analysis of medical records. Anti-HCV antibodies were detected by chemiluminescence immunoassay.

RESULTS:
a total of 12.9% of HIV+ patients were positive for anti-HCV antibodies, 64.1% were men and 35.9% women, with mean age of 44.5 years (24-66). The frequency of HCV among men was 16.7% and among women 9.1%. HCV prevalence was associated to HIV infection when compared to the general population. The parenteral route of transmission was the most frequent among coinfected patients (46.1%), and the sexual transmission among HIV+/HCV- (71.8%). The frequency of intravenous drug users was higher among the coinfected patients (61.5%) compared to the non coinfected (12.6%).

CONCLUSION:
the prevalence of coinfection with HCV in HIV+ patients is 12.9%, 88 times higher than in the general population in Curitiba. The most frequent route of transmission in the coinfected patients is parenteral, but the sexual route is also representative (34.6%).

Implementation of Rapid HIV & HCV Testing Within Harm Reduction Programs for People Who Inject Drugs

Including HCV and HIV rapid tests in harm reduction programmes (HRP) for people who inject drugs (PWID) can increase detection of these infections in high-risk populations who do not seek conventional health care.

AIMS:
To assess acceptability and feasibility of rapid HIV and HCV tests in HRP; to identify HIV and HCV prevalence rates in HRP; to identify the percentage of PWID with a reactive test that attend hospital for confirmation and follow-up. Rapid oral tests for HCV and HIV were offered to users of 13 HRP from both mobile units and facility-based centres. 

A total of 172 HCV and 198 HIV tests were performed, with a refusal rate of 1.7% and 10.4%, respectively. Injectors made up 64.9% of all drug users and 35.1% did not inject drugs. Overall, 20.3% of HCV tests and 2.5% of HIV test were reactive. Only 24 of the 35 reactive HCV could be confirmed (68.6%) and one was false-negative. Of the five HIV reactive cases, only two could be confirmed (40%) with 1 false-positive case.

 Acceptability of rapid HIV and HCV tests among HRP users was high. The usefulness of oral rapid tests in HRP has been demonstrated, especially in mobile HRP.
