Global prevalence of hepatitis C in prisoners: a comprehensive systematic review and meta-analysis. Arch Virol 2022; 167:1025-1039. [PMID: 35165781 DOI: 10.1007/s00705-022-05382-1] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/19/2021] [Accepted: 12/21/2021] [Indexed: 12/11/2022]
Abstract
Hepatitis C virus (HCV), one of the most significant causes of liver inflammation, has a high annual mortality rate. The unfavorable hygiene conditions and inadequate health monitoring in many prisons increase the risk of blood-borne infections such as hepatitis C. The growing incidence of this disease among prisoners results in overspill transmission to the general population from undiagnosed prisoners that have been released. Therefore, the aim of this study was to investigate the prevalence of hepatitis C among the world's prison population. A systematic review and meta-analysis of studies on the prevalence of hepatitis C was carried out using the keywords "Prevalence", "Hepatitis C", and "Prisoner" in the Iranian and international databases SID, MagIran, Iran Doc, Science Direct, Scopus, PubMed, and Web of Science (WoS) from January 1990 to September 2020. After transferring the articles to the information management software EndNote and eliminating duplicate studies, the remaining studies were reviewed based on inclusion and exclusion criteria, three stages of primary and secondary evaluation, and qualitative evaluation. Comprehensive meta-analysis software and Begg and Mazumdar and I2 tests were used for data analysis and assessment of dissemination bias, and heterogeneity, respectively. Out of 93 studies (22 from Asia, 26 from Europe, seven from Africa, 29 from America, and nine from Australia) with a total sample size of 145,823 subjects, the prevalence of hepatitis C in prisoners worldwide was estimated to be 17.7% (95% confidence interval, 15-20.7%). The highest prevalence of hepatitis C on the continents included in this study was reported in prisoners incarcerated in Australia and Oceania, with 28.4% (95% CI: 21.6-36.4) in nine studies, and Europe, with 25.1% (95% CI: 19.4-31.8) in 26 studies. All studies used an ELISA test for the detection of HCV antibodies. The results showed a prevalence of HCV of 17.7% in prisoners worldwide, ranging between 10 and 30% over five continents (Asia, Europe, America, Africa, and Australia and Oceania). The highest prevalence was reported in Australia and Oceania (28.4%), indicating the need to pay more attention to this issue on the continent. It is necessary to reduce the incidence of the disease in prisons by appropriate policy-making and the development of accurate and practical programs, including the distribution of free syringes and examination, testing, and screening of prisoners.

Abstract
Background The 69th World Health Assembly approved the Global Health Sector Strategy to eliminate hepatitis C virus (HCV) infection by 2030. In Brazil, efforts have been undertaken to achieve this goal; there are, however, great challenges. It is important to understand the disease profile in different regions of the country in order to design strategies to fight the disease nationwide. The objective of this study was to analyse the time trend of the incidence and mortality of hepatitis C in Brazil during the period from 2008 to 2018 according to sociodemographic and clinical characteristics. Methods All newly diagnosed cases of hepatitis C reported between 2008 and 2018, in all regions of Brazil, were included. The indicators were obtained from the databases of the Brazilian Ministry of Health. For the time series analysis, a joinpoint regression model was used. Results Between 2008 and 2018, 136,759 newly diagnosed cases of hepatitis C were reported considering anti-HCV and HCV RNA positivity, and 271,624 newly diagnosed cases were reported considering one or another positive test. The majority of the records were concentrated in the Southeast (61%) and South (26.2%) Regions. The joinpoint regression model indicated an increasing trend in the detection rate of hepatitis C in Brazil, but there was a decreasing trend in the mortality rate during the period analysed. Conclusions Differences were observed in the time trend of hepatitis C and in the sociodemographic and clinical characteristics in different regions of Brazil. These data can provide support to design strategies for the elimination of hepatitis C in Brazil, according to regional particularities.

Abstract
Viral hepatitis are widely spread infectious diseases caused by a variety of etiological agents that displays liver tropism as a common characteristic. A descriptive, cross-sectional, observational and retrospective study was conducted through the analysis of viral hepatitis medical records treated and diagnosed from 2010 to 2015. The relationship between the variables were made through the chi-square test. 632 viral hepatitis medical records were analyzed. The highest number of cases happened in 2011. Hepatitis A virus (HAV) infection was predominant. The most affected age group was < 20 years and the highest number of cases observed in this age group was related to HAV (p<0.001). The acute clinical form was predominant, with 70.2% of the cases. 92.3% of which corresponded to HAV infection (p<0.001). Most of the cases occurred in the brown race and male gender. Moreover, regarding the probable source/mechanism of infection, the contact with suspicious water/food for hepatitis A cases was highlighted. The sexual form predominated in HBV infection and previous history of blood transfusion in cases of hepatitis C. Most cases were spotted in the mesoregion of Eastern Alagoas, especially in the capital Maceió. It must be observed the importance of knowing the profile of this disease in order to understand its dissemination and thus have subsidies for the creation of actions and strategies to combat the infection.

Seroprevalence of HBV and HCV in female sex workers from four cities in the state of Pará, northern Brazil. J Med Virol 2021; 93:3730-3737. [PMID: 33368401 DOI: 10.1002/jmv.26759] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2020] [Revised: 12/02/2020] [Accepted: 12/22/2020] [Indexed: 12/25/2022]
Abstract
Female sex workers (FSWs) represent a high vulnerability group for the acquisition of sexual and parenteral infections such as hepatitis B virus (HBV) and hepatitis C virus (HCV) infections. The present study aimed to determine the prevalence of serological markers and risk factors associated with exposure to HBV and HCV among FSWs in the state of Pará, Brazil. A cross-sectional study using principles of the time location sampling (TLS) method was conducted in four cities (Belém, Bragança, Barcarena, and Augusto Corrêa) of the state of Pará, from 2005 to 2006. In total, 365 FSWs were interviewed using a standardized questionnaire. Blood samples were collected and tested for serological markers of exposure to HBV and HCV using an enzyme immunoassay. The overall prevalence of exposure to HBV and HCV was 36.7% and 7.7%, respectively. The prevalence of surface antigen of HBV was 3.0%. The prevalence of anti-HBc and anti-HBc+ anti-HBs antibodies were 6.3% and 27.4%. Very few (4.7%) FSWs had vaccine immunity against HBV (anti-HBs antibodies only). The prevalence of anti-HCV antibodies was 7.7%. Low monthly income, drug usage, and unprotected sex were some of the social characteristics associated with exposure to the viruses using different analysis. The seroprevalence of HBV and HCV infections among FSWs in four cities of the state of Pará is high when compared to the general population of Brazil, but similar to those found in FSWs in other nondeveloped countries. The prevalence of HBV was higher in Belém, while the prevalence of HCV was higher in the other three cities, highlighting the importance of establishing control and prevention programs to reduce the risk of acquiring these viruses in Pará.

Hepatitis C Virus among Female Sex Workers: A Cross-Sectional Study Conducted along Rivers and Highways in the Amazon Region. Pathogens 2019; 8:pathogens8040236. [PMID: 31739623 PMCID: PMC6963267 DOI: 10.3390/pathogens8040236] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2019] [Revised: 11/07/2019] [Accepted: 11/11/2019] [Indexed: 12/12/2022] Open
Abstract
Background: Previous studies found a high prevalence of pathogens among female sex workers (FSWs) in the Amazon region, and established their parenteral and sexual transmission. This study estimated the prevalence of hepatitis C virus (HCV) infection and associated risk factors, and the frequency of HCV genotypes and resistance-associated substitutions (RASs) in this vulnerable group. Methods: Distinct sampling methods were used to access 412 FSWs in cities and riverside communities in the Amazon region from 2015 to 2018. Three methods for HCV diagnosis were used to determine infection status. HCV genotypes and RASs were identified by sequencing and nucleotide fragment analysis. An association between HCV infection and exposure factors was determined by bivariate and multivariate analysis. Results: In total, 44 (10.7%) FSWs were exposed to HCV, and 32 (7.8%) of them had active infection. Nine socioeconomic characteristics and risky sexual behaviors were associated with HCV exposure, particularly unprotected sex and condom exemption for the clients who paid extra money. Genotype 1 (81.3%) and 3 (18.7%) were detected. The frequency of FSWs with RASs was 23.1% (6/26) for grazoprevir related to the occurrence of substitutions Y56F and S122G. Conclusions: HCV infection among FSWs is highly prevalent and dominated by genotype I. Urgent preventive and treatment measures are required to reduce HCV infection in FSWs and the general population.

Hepatitis C virus infection among illicit drug users in an archipelago of the Amazon. Arch Virol 2017; 163:617-622. [PMID: 29164400 DOI: 10.1007/s00705-017-3656-y] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2017] [Accepted: 10/12/2017] [Indexed: 10/18/2022]
Abstract
Hepatitis C virus (HCV) infection causes acute and chronic liver disease and may lead to cirrhosis, liver failure or hepatocellular carcinoma. The behavior of illicit drug users (DUs) typically exposes them to risks of viral infection. In the Brazilian Amazon region, a number of studies have identified high rates of drug use among adolescents, and a high prevalence of HBV infection in DUs, disseminated by sexual and parenteral activities. However, the epidemiological scenario of HCV infection in the region is still poorly understood. This study determined the prevalence, genotypes, and risk factors for HCV infection among DUs of the Marajó Archipelago. This cross-sectional study collected samples and epidemiological information from DUs in 11 municipalities. The diagnosis was established by EIA and real-time PCR, and the samples were genotyped by multiplex real time PCR. The data were analyzed by simple and multiple logistical regression. In 466 DUs, 28.3% had anti-HCV antibodies, and 25.5% had HCV-RNA. In 92 injecting drug users, 88.0% had anti-HCV antibodies, and 80.4% had HCV-RNA. Genotypes 1 and 3 were detected, with three cases of mixed infections. The multivariate analysis indicated associations of HCV infection with age (≥ 35 years), tattoos, intravenous drug use, shared use of injection equipment, and the daily and long-term (> 3 years) use of illicit drugs. These findings will contribute to the development of effective measures for the prevention of HCV infection among Brazilian DUs, as well as its general population.

Abstract
INTRODUCTION Few studies have addressed the primary characteristics of patients infected with hepatitis B virus (HBV) in the general population, especially those living in small- and medium-sized cities in Brazil. We aimed to determine the clinical, demographic, and epidemiologic characteristics of patients diagnosed with HBV who were followed up at an infectious diseases clinic of a public hospital in State of São Paulo, Brazil. METHODS Medical records of patients aged >18 years and diagnosed with HBV infection between January 2000 and December 2013 were reviewed. RESULTS Seventy-five patients were enrolled with male-female main infection-associated risk factors; 9 (12%) were co-infected with human immunodeficiency virus (HIV), 5 (6.7%) with hepatitis C virus (HCV), and 3 (4%) were co-infected with both HIV and HCV. Antiviral HBV therapy was applied in 21 (28%) patients and tenofovir monotherapy was the most prescribed medication. After approximately 2 years of antiviral treatment, the HBV-DNA viral load was undetectable in 12 (92.3%) patients and lower levels of alanine aminotransferase were found in these patients. CONCLUSIONS Over a 13-year interval, very few individuals infected with HBV were identified, highlighting the barriers for caring for patients with HBV in developing countries. New measures need to be implemented to complement curative practices.

Risk for hepatitis B and C virus transmission in nail salons and barbershops and state regulatory requirements to prevent such transmission in the United States. JOURNAL OF PUBLIC HEALTH MANAGEMENT AND PRACTICE 2016; 20:E20-30.

Abstract
CONTEXT The potential for hepatitis B and C virus (HBV/HCV) transmission in nail salons and barbershops has been reported, but a systematic review has not been conducted. These businesses are regulated by state cosmetology or barbering boards, but adequacy of sanitary requirements has not been evaluated. OBJECTIVES To conduct literature review to assess risk for HBV/HCV transmission in nail salons and barbershops and to evaluate sanitary requirements in HBV/HCV prevention in these businesses in 50 states and District of Columbia. DESIGN Several search engines were used for literature search. Studies that quantified risks associated with manicuring, pedicuring, or barbering were included. State requirements for disinfection and sterilization were reviewed and evaluated. MAIN OUTCOME MEASURE For literature review, odds ratios, 95% confidence intervals, and confounding adjustment were extracted and evaluated. For regulation review, requirements for disinfection or sterilization for multiuse items in nail salons and barbershops were assessed according to the US federal guidelines. RESULTS Forty-six studies were identified and 36 were included in this study. Overall, the results were not consistent on risk for HBV/HCV transmission in nail salons and barbershops. For sanitary requirements, disinfection with an Environmental Protection Agency-registered disinfectant is required in 39 states for nail salons and in 26 states for barbershops. Sterilization was described in 15 states for nail salons and in 11 states for barbershops, but the majority of these states listed it as an optional approach. Sanitary requirements are consistent in states where 1 board regulates both businesses but are substantially discrepant in states with separate boards. CONCLUSIONS Current literature cannot confirm or exclude the risk for HBV/HCV transmission in nail salons and barbershops. Existing sanitary requirements are adequate in the majority of states, but compliance is needed to prevent HBV/HCV transmission in these businesses.

Abstract
This study evaluated epidemiological factors for HCV infection
associated with sharing perforating and cutting instruments among candidates for
blood donation (CBD) in the city of Belém, Pará, Brazilian
Amazon. Two definitions of HCV infection cases were used: anti-HCV positivity
shown by EIA, and HCV-RNA detection by PCR. Infected and uninfected CBD
completed a questionnaire about possible risk factors associated with sharing
perforating and cutting instruments. The information was evaluated using simple
and multiple logistic regressions. Between May and November 2010, 146
(1.1%) persons with anti-HCV antibodies and 106
(0.8%) with HCV-RNA were detected among 13,772 CBD in Belém.
Risk factors associated with HCV infection based on the EIA (model 1)
and PCR (model 2) results were: use of needles and syringes sterilized
at home; shared use of razors at home, sharing of disposable razors in
barbershops, beauty salons etc.; and sharing manicure and pedicure material. The
models of HCV infection associated with sharing perforating and cutting
instruments should be taken into account by local and regional health
authorities and by those of other countries with similar cultural practices, in
order to provide useful information to guide political and public strategies to
control HCV transmission.

Abstract
BACKGROUND & AIMS The prevention and control of HCV infection is complex and challenging in terms of describing risk factors and modes of transmission. This meta-analysis was conducted to summarize the best available data on HCV risk factors worldwide and in Egypt. METHODS Through exhaustive literature searches (1989-2013) of HCV risk factors, 357 original eligible articles were included in this study. RESULTS The highest detected risk was intravenous drug users (IDUs) (OR = 9.6) followed by HIV infection (OR = 4.9), having an IDU partner (OR = 4.1), HBV infection (OR = 3.5), Caesarean section (CS) (OR = 3.35), blood transfusion (OR = 3.2) and having an HCV+ partner (OR = 3). Organ transplantation, hospital admission, haemodialysis and having a sexually transmitted infection carry 2.96, 2.4, 2.18 and 2 risks of having HCV respectively. Other significant risk factors included poor education, older age, sharing sharp or blunt objects, MSM, tattooing, hijama, body piercing, minor operations and medical procedures. Some risks showed a decrease over the previous decade, including blood transfusion, organ transplantation, IDUs, IDU partner and CS. Others showed rising risks, including having an HCV+ partner, MSM and suffering from STI. In Egypt, male gender, rural residence, acupuncture and receiving parenteral antischistosomal treatment were significant risks, while neither HIV nor HBV were found to carry a risk of HCV infection. CONCLUSION Blood transfusion, organ transplantation, CS, IDUs, haemodialysis, minor operations and medical procedures are established risk factors. Attention and urgent intervention should be given to the sexual route of transmission, as well as that through minor operations and medical procedures.

Abstract
Beauty treatments, such as tattooing, piercing, manicures, pedicures, and barbershop shaving, can pose an important risk of virus transmission. This study was conducted to determine hepatitis A virus (HAV), hepatitis B virus (HBV), and hepatitis C virus (HCV) prevalence in a sample of beauticians from Rio de Janeiro (Southeast Brazil) and to assess the knowledge and attitudes of these professionals regarding viral hepatitis and their practices during their activities. One hundred nineteen beauticians were recruited in September 2010. Serum samples were tested for total anti-HAV, total anti-HBc, HBsAg, anti-HBs, and anti-HCV reactivity. A questionnaire was administered to identify socio-demographic risk factors and to determine knowledge and attitudes regarding viral hepatitis. Prevalence was 73.9% for total anti-HAV, 0% for HBsAg, 5.9% for anti-HBc, 23.6% for anti-HBs, and 0.8% for anti-HCV. Most professionals (81.5%) were well informed (4-7 correct answers) and reported the use of disposable sandpaper and nail sticks and sterilized pliers, but only 40% of them reported adequate processes of disinfection/sterilization. In conclusion, a high prevalence of HAV infection and a low prevalence of HBV and HCV infection were observed among beauticians. In addition, most of these individuals were not immune to HBV, indicating the need for vaccination campaigns targeting these professionals. Most of these professionals were well informed regarding viral hepatitis, although there was a gap in knowledge regarding disinfection and sterilization procedures. Public health prevention strategies should be adopted to improve education about disinfection/sterilization procedures for manicures and pedicures.

Abstract
In 2009, we conducted a case-control study to explore the routes of HCV transmission in people living with HIV/AIDS (PLHIV) in Cambodia. Cases were HCV/HIV co-infected patients (who tested RT-PCR positive for HCV-RNA or had confirmed presence of HCV antibodies) (n = 44). Controls were HIV mono-infected patients, with no HCV antibodies (n = 160). They were recruited among the PLHIV presenting at one national reference centre of HIV/AIDS. Multivariate analysis showed that factors associated with the co-infection were the age older than 50 years (OR 5.4, 95 % confidence interval (CI) 1.5-19.6), the exposure to multiple parenteral infusions before the year 2000 (OR 3.4, 95 % CI 1.5-7.6), to surgery (OR 2.6, 95 % CI 1.2-5.7) and to fibroscopy (OR 2.4, 95 % CI 1.0-5.7). These results show the need to implement HCV screening in PLHIV, to support the implementation of national infection control guidelines, and to reinforce public awareness on the risks linked to parenteral medications.

Epidemiological aspects of HCV infection in non-injecting drug users in the Brazilian state of Pará, eastern Amazon. Virol J 2014; 11:38.

Abstract
BACKGROUND Currently, sharing of drug paraphernalia is the main form of HCV transmission worldwide. In South America, consistent findings indicate that shared sniffing equipment is an important factor in the spread of HCV among non-injecting drug users. Epidemiological data on the status of HCV infection in illicit drug users in the Amazon region are scarce, although reports of clinical cases of hepatitis or pathologies associated with HCV infection in other population groups are numerous. Thereby, this study investigated the prevalence, genotype frequency, and epidemiological factors associated with HCV infection in non-injecting drug users in the state of Pará, eastern Amazon. RESULTS During 2008-2011, 300 non-injecting drug users attending drug-treatment centers participated in this study. Most non-injecting drug users were male (63.7%). The mean age was 32.5 years. The non-injecting drugs most consumed were: cannabis (15.6%), cocaine paste (21.3%), and oxi cocaine (25.7%). Tobacco (60.9%) and alcohol (79.4%) were also commonly consumed. One hundred six (35.1%; CI 95%: 29.8 - 41.1) non-injecting drug users presented anti-HCV antibodies by EIA. The HCV-RNA prevalence was 28.0% (95% CI: 20.6 - 35.8). Genotypes 1 (76.9%) and 3 (23.1%) of HCV have been identified. A multivariate analysis demonstrated that HCV infection was independently associated with the following factors: "age (≥ 35 years)", "tattoos", "use of a needle or syringe sterilized at home", "shared use of drug paraphernalia", "uses drugs for more than 5 years", and "use of drugs everyday". CONCLUSIONS This study revealed a high prevalence of HCV infection in non-injecting drug users, and most infections are occasioned by genotype 1. Likely, HCV transmission is associated with the tattoos, the use of needle or syringe sterilized at home by people over the age of 35 years, and sharing, time and frequency of use of non-injecting drugs. These findings should serve as an incentive for the establishment of a program of Hepatitis C prevention and control by the local public-health authorities in order to develop effective policies and strategies for contain the spread of HCV infection.

Abstract
The aim of the present work was to compare hepatitis C prevalence, genotypes, and risk factors between prisoners and non-prisoners in the city of Colatina, Espírito Santo, Brazil. This cross-sectional study involved approximately 1,600 residents and 730 prisoners, all of whom were living in Colatina. The percentage of individuals who tested positive for anti-HCV was 0.1% (2/1,600) in the non-prisoner group and 1.0% (7/730) in the prisoner group, confirming a higher risk of hepatitis C in the latter group. The percentage of subjects who progressed to HCV-RNA negative was 11.1% (1/9), confirming the high probability of evolution to chronicity. Genotype 1 was the most predominant genotype found. Factors associated with increased risk of hepatitis C were being male, being institutionalized, having an income of less than three minimum wages, having low educational attainment, and using injected drugs. Alcohol use, pain in the liver, migraine, and reported history of hepatitis were markedly associated with hepatitis C. The prison population tested positive for anti-HCV at a higher rate than the non-prison population.

Abstract
In this study, the prevalence, genotype frequency, and risk factors for HCV infection in 384 cocaine users were determined. One hundred twenty-four (32.3 %) cocaine users had anti-HCV antibodies and 120 (31.3 %) had HCV-RNA. Genotyping results indicated the predominance of genotypes 1 (73.3 %) and 3 (26.7 %). Multivariate analysis showed an association of HCV infection with tattoos, shared use of paraphernalia, daily cocaine use, and a long history of cocaine use. The epidemiological aspects of HCV infection among cocaine users presented here should serve as an incentive for the establishment of a program of hepatitis C prevention and control by the local public-health authorities in the Amazon.

Abstract
The purpose of this study was to correlate morphologic and hemodynamic Doppler ultrasound findings as indicators of the degree of inflammation and fibrosis and to diagnose chronic vital hepatitis complications and progression. A prospective, descriptive study of a case series was conducted that analyzed Doppler ultrasound images of the liver and portal system and used the portal vein congestion index, hepatic and splenic artery impedance indices, and the liver vascular index. Of 50 patients positive for antibodies against hepatitis C virus, morphologic changes highlighted increased hepatic parenchyma echogenicity in 24%, and increased gall blander echogenicity and wall thickness in 4%. The most common hemodynamic changes observed were reduced flow velocity in the portal vein trunk in 26%, congestion index changes in 12%, liver vascular index changes in 16%, and splenic and hepatic artery impedance index changes in 14%. These indices were shown to be associated with alanine aminotransferase levels, which suggested that they are important liver damage indicators in the early phase of infection with hepatitis C virus.
