Hepatitis B and Hepatitis C Viral Infections and Associated Factors Among Prisoners in Northeast Ethiopia

Generalized linear modeling of HCV infection among medical waste handlers in Sidama region, Ethiopia

Background

There is limited evidence on prevalence and risk factors for hepatitis C virus (HCV) infection among waste handlers in Sidama region, Ethiopia; however, this knowledge is necessary for effective prevention of HCV infection in the region.

Methods

A cross-sectional study was conducted among randomly selected waste collectors from October 2021 to 30 July 2022 in different public hospitals of Sidama region of Ethiopia. Serum samples were collected from participants and screened for anti-HCV using rapid immunochromatography assay. Socio-demographic and risk factor information of waste handlers was gathered by pretested and well-structured questionnaires The generalized linear model (GLM) was conducted using R software, and P-value <0.05 was declared statistically significant.

Results

From a total of 282 participating waste handlers, 16 (5.7%) (95% CI = 4.2-8.7) were infected with hepatitis C virus. Educational status of waste handlers was the significant demographic variable that was associated with hepatitis C virus (AOR = 0.055; 95% CI = 0.012-0.248; P = 0.000). More married waste handlers, 12 (75%), were HCV positive than unmarried, 4 (25%) and married waste handlers were 2.051 times (OR = 2.051, 95% CI = 0.644-6.527, P = 0.295) more prone to HCV infection, compared to unmarried, which was statistically insignificant. The GLM showed that exposure to blood (OR = 8.26; 95% CI = 1.878-10.925; P = 0.037), multiple sexual partners (AOR = 3.63; 95% CI = 2.751-5.808; P = 0.001), sharp injury (AOR = 2.77; 95% CI = 2.327-3.173; P = 0.036), not using personal protective equipment (AOR = 0.77; 95% CI = 0.032-0.937; P = 0.001), contact with jaundiced patient (AOR = 3.65; 95% CI = 1.093-4.368; P = 0.0048) and unprotected sex (AOR = 11.91; 95% CI = 5.847-16.854; P = 0.001) remained statistically significantly associated with HCV positivity.

Conclusions

The study revealed that there was a high prevalence of hepatitis C virus infection among waste handlers in Sidama region, Ethiopia. This demonstrated that there is an urgent need to increase preventative efforts and strategic policy orientations to control the spread of the hepatitis C virus.

SEROPREVALENCE OF HBsAg, HCV AND HIV AND ASSOCIATED RISK FACTORS IN A CORRECTIONAL FACILITY IN SOUTHERN NIGERIA: A CROSS-SECTIONAL STUDY

Background

Incarceration has been known to increase the transmission of some blood-borne viruses such as hepatitis B virus (HBV), hepatitis C virus (HCV) and human immunodeficiency virus (HIV). Correctional centres are thought to be the reservoir of these infections, thereby constituting a risk to the larger society when the individuals are released. Objectives: The study determined the seroprevalence of HBV, HCV, and HIV and associated factors for infections among people living in a correctional centre (PLCC) in Southern Nigeria.

Methodology

This was a cross-sectional study involving PLCC. An objectively structured questionnaire was administered to obtain socio-demographic information and data about the history of recreational drug use, previous incarceration, and duration of incarceration. Blood samples were screened for hepatitis B virus, hepatitis C virus and HIV.

Results

A total of 302 PLCC participated in this study with a male: female ratio of 12:1. The sero-prevalence of hepatitis B (HBV), hepatitis C (HCV) and HIV infections were 6.6%, 2% and 3.6% respectively. The co-infection rate of HBV/ HCV was 0.3% and HIV/HBV co-infection also 0.3%. There was a significant association between gender, ethnicity, monthly income and HBV status. History of genital rashes/discharge was also significantly associated with HCV status while 'HIV status' was associated with sharing of personal belongings, history of genital rashes/discharge and cigarette smoking.

Conclusion

HBV, HCV and HIV infections are prevalent among PLCC. The infections were associated with some socio-demographic and clinical variables.

Hepatitis B and hepatitis C virus infections and associated factors among prisoners in Gondar City, Northwest Ethiopia

BACKGROUND

Globally, hepatitis B virus (HBV) and hepatitis C virus (HCV) cause considerable morbidity and mortality from their acute and chronic infections. The transmission of the viruses within the prisons is high due to overcrowding, and other risk behaviors such as drug use, and unsafe sexual practices. This study aimed at determining the prevalence and associated factors of HBV and HCV infections among prisoners in Gondar city, Northwest Ethiopia.

METHODS

A cross-sectional study was conducted in the Gondar City Prison Center from May 1, 2022, to July 30, 2022. A total of 299 prison inmates were selected by using a systematic random sampling technique. A semi-structured questionnaire was used to collect data on sociodemographic, clinical, behavioral and prison related factors. Five milliliters of blood sample were collected, and the serum was separated from the whole blood. The serum was tested for HBV surface antigen (HBsAg) and anti-HCV antibody by using an Enzyme-Linked Immunosorbent Assay (ELISA). Data was entered using EpiData version 4.6.0 and exported to SPSS version 20 for analysis. Logistic regression analysis was done to assess the association between the independent variables and HBV and HCV infections. P-values < 0.05 were considered statistically significant.

RESULTS

The overall seroprevalence of HBV or HCV infections was 10.4%. The seroprevalence of HBV and HCV infections was 7.0% and 4.0%, respectively. It has been demonstrated that having several heterosexual partners, sharing sharp materials in prison, having longer imprisonment, and having a body tattoo are significantly associated with HBV infection. The presence of a body tattoo, a history of surgical procedures, and previous imprisonment are associated risk factors for HCV infection.

CONCLUSION

The prevalence of HBV and HCV were high-intermediate and high, respectively. Therefore, preventative and control initiatives are needed in prisons to decrease the rate of infection and transmission.

Serological Evidence and Associated Factors of Hepatitis B Virus and Hepatitis C Virus Among Waste Handlers: A Cross-Sectional Study from Northeastern Ethiopia

Background

The World Health Organization (WHO) has identified viral hepatitis, caused by hepatitis B virus (HBV) and hepatitis C virus (HCV), as one of the main global public health issues. People who work in the collection of waste materials, from either household or medical environments, are at greatest risk.

Objective

To determine the prevalence of and factors associated with HBV and HCV among medical and domestic waste handlers in Northeast Ethiopia.

Methods

A comparative cross-sectional study was conducted from January to April 2021 at selected healthcare facilities and municipal settings in Dessie town, Northeast Ethiopia. The sample size was determined using a double population proportion formula, and a simple random sampling technique was employed to select 70 individuals in the medical waste handlers (MWHs) group and 206 in the domestic waste handlers (DWHs) group. Five milliliters of venous blood was collected from each participant and tested for HBV and HCV using an enzyme-linked immunosorbent assay. Data were analyzed using SPSS version 23; the prevalence was computed, Fisher's exact test was used, and logistic regression was applied.

Results

A total of 276 study participants were enrolled and the overall seroprevalence of hepatitis virus was 5.1%. The seroprevalence of HBV infection among MWHs and DWHs was 8.6% and 1.9%, respectively. The overall seroprevalence of HCV infections among MWHs and DWHs was 4.3% and 0.5%, respectively. Medical waste handling, having a history of needle stick injury, and not using personal protective equipment were factors significantly associated with HBV infection.

Conclusion

The overall seroprevalence of viral hepatitis was high. The prevalence of HBV infection among MWHs was in line with the high endemicity classification of the WHO, and there was a significant difference in prevalence between DWHs and MWHs. Both groups of waste handlers should receive proper attention to protect them from HBV and HCV infection.

Seroprevalence and Associated Factors of Hepatitis B and Hepatitis C Viral Infections Among Prisoners in Tigrai, Northern Ethiopia

Background

Hepatitis B and C viruses are important health and socioeconomic problem across the globe, with a remarkable number of diseases and deaths in sub-Saharan African countries. The burden of hepatitis is unknown in the prison settings of Tigrai. Therefore, we aimed to describe the seroprevalence and associated factors of hepatitis B and C viruses among prisoners in Tigrai, Ethiopia.

Methods

A cross-sectional study was carried out from February 2020 to May 2020 at the prison facilities of Tigrai. Demographics and associated factors were collected from 315 prisoners prospectively. Five milliliters of blood was collected and tested using rapid tests kits of HBsAg (Zhejiang orient Gene Biotech Co., Ltd., China) and HCV antibodies (Volkan Kozmetik Sanayi Ve Ticaret Ltd. STI, Turkey). Positive samples were confirmed using enzyme-linked immunosorbent assay (ELISA) (Beijing Wantai Biological Pharmacy Enterprise Co. Ltd). Data were analyzed using the Statistical Package for Social Sciences (SPSS) version 20 and p<0.05 was considered statistically significant.

Results

The overall seroprevalence of HBV and HCV were 25 (7.9%) and 1 (0.3%), respectively. The majority of hepatitis B viral infections were identified from the age groups of 18-25 years (10.7%) and unmarried prisoners (11.8%). Prisoners greater than 100 per cell (AOR=3.95, 95% CI=1.15-13.6, p=0.029) and with a history of alcohol consumption (AOR=3.01, 95% CI=1.17-7.74, p=0.022) were significantly associated with HBV infections.

Conclusion

The seroprevalence of HBV among prisoners was nearly high or borderline (7.9%) with a very low HCV prevalence (0.3%). HBV was most prevalent among young adults, those housed with a large number of prisoners per cell, and those who had a history of alcohol consumption. This study recommends that there should be prison-focused intervention, including regular health education, with the emphasis on the mode of transmission and introducing HBV screening policy for prisoners, especially when they enter the prison.

Prevalence of overt and occult hepatitis B virus infection among an incarcerated population of Central-Western Brazil

Brazilian prison complexes are characterized by overcrowded cells and precarious conditions, leading to chronically low vacancy. Brazilian studies involving overt and occult infection (OBI) in this population are still scarce despite the vulnerability of people deprived of liberty to hepatitis B. Therefore, this study estimated the prevalence of HBV infection (overall and OBI) in individuals deprived of liberty in prisons in Central-Western Brazil. In addition, factors associated with HBV infection were evaluated. This cross-sectional study was conducted with a total of 1083 prisoners who were tested for serological hepatitis B markers and HBV DNA from 2017 to 2020. Factors associated with lifetime HBV infection were investigated using logistic regression. An overall prevalence of HBV infection of 10.1% (95% CI: 8.42-12.11) was detected. Only 32.8% (95% CI: 30.08-35.76) had isolated anti-HBs positivity (serological evidence of HBV vaccination). Indeed, more than half of the population was susceptible to HBV infection (57.1%; 95% CI: 54.15-60.13). HBV DNA was detected in one HBsAg-positive sample (n=1/9; 11%). Also, HBV DNA was detected in five HBsAg-negative samples (n=5/1074), resulting in a prevalence of 0.5% (95% CI: 0.15-1.08) for occult infection. After the multivariate analysis, sexual intercourse with a partner living with HIV was a predictor independently associated with HBV exposure (OR: 4.3; 95% CI: 1.26-14.55; p<0.020). These data demonstrate the need for preventive measures, mainly aimed at health education and better strategies for hepatitis B screening to control this infection in prisons more effectively.

Hepatitis C prevalence in incarcerated settings between 2013–2021: a systematic review and meta-analysis

Background

The introduction of highly effective direct-acting antiviral therapy has changed the hepatitis C virus (HCV) treatment paradigm. However, a recent update on HCV epidemiology in incarcerated settings is necessary to accurately determine the extent of the problem, provide information to policymakers and public healthcare, and meet the World Health Organization's goals by 2030. This systematic review and meta-analysis were performed to determine the prevalence of HCV Ab and RNA in incarcerated settings.

Methods

For this systematic review and meta-analysis, we searched PubMed, Embase, Scopus, and Web of Science for papers published between January 2013 and August 2021. We included studies with information on the prevalence of HCV Ab or RNA in incarcerated settings. A random-effects meta-analysis was done to calculate the pooled prevalence and meta-regression to explore heterogeneity.

Results

Ninety-two unique sources reporting data for 36 countries were included. The estimated prevalence of HCV Ab ranged from 0.3% to 74.4%. HCV RNA prevalence (available in 46 sources) ranged from 0% to 56.3%. Genotypes (available in 19 sources) 1(a) and 3 were most frequently reported in incarcerated settings. HCV/HIV coinfection (available in 36 sources) was highest in Italy, Estonia, Pakistan, and Spain. Statistical analysis revealed that almost all observed heterogeneity reflects real differences in prevalence between studies, considering I² was very high in the meta-analysis.

Conclusions

HCV in incarcerated settings is still a significant problem with a higher prevalence than in the general population. It is of utmost importance to start screening for HCV (Ab and RNA) in incarcerated settings to give clear, reliable and recent figures to plan further treatment. This is all in the context of meeting the 2030 WHO targets which are only less than a decade away.

Prevalence of sexually transmitted infections and associated risk behaviors in prisoners: A systematic review

BACKGROUND AND AIMS

Sexually transmitted infections (STIs) are one of the major health concerns globally. Generally, prisoners are at higher risks for STIs due to risk factors including; drug-use, high-risk sexual behaviors, densely populated prisons, and poor living conditions. Therefore, we aimed to conduct a systematic review to evaluate the existing data on STI prevalence, and its associated risk factors among prisoners.

METHODS

We conducted a systematic search of the literature using the keywords in Scopus, PubMed, Web of Science, and Google Scholar online databases. We selected all the relevant original studies in English through title/abstract and full-text screening process.‎.

RESULTS

Based on the inclusion and exclusion criteria, we selected and reviewed 32 studies out of 96 identified papers. The most important STI-associated risk factors among prisoners were drug use, low educational levels, and unsafe sex. The prevalence of STIs was heterogenous in selected studies and was reported as follows; Human Immunodeficiency Virus (HIV) (0%-14.5%), hepatitis B viruses (HBV) (0.04%-27.23%), hepatitis C viruses (HCV) (0.17%-49.7%), Syphilis (0.2%-22.1%), Chlamydia Trachomatis (CT) (1.02%-6.7%), Gonorrhea (0.6%-7.8%), and herpes simplex virus-2 (HSV-2) 22.4%.

CONCLUSION

This systematic review indicates that the prevalence of STIs (HIV, HBV, HCV, Syphilis, Chlamydia Trachomatis, Gonorrhea, and HSV-2) among prisoners appears to be higher than the general population, with drug abuse, low educational levels, and unsafe sex as major risk factors.
