Abstract

Objective: Female sex workers (FSWs) are vulnerable to human alphaherpesvirus 2 (HSV-2) infection due to their high numbers of sexual partners. The objective of this study was to evaluate the seroprevalence and risk behaviours associated with HSV-2.Methods: A cross-sectional study was conducted in Mato Grosso do Sul, Brazil. A total of 376 FSWs were recruited by respondent-driven sampling (RDS) methodology and answered an epidemiological questionnaire. Blood samples were collected to test for HSV-2 antibodies using commercial ELISA and for HSV-2 DNA using real-time PCR.Results: The seropositivity was 47.3% (178/376) for HSV-2 IgG and 10.1% (38/376) for HSV-2 IgM. HSV-2 viraemia was detected in two infected FSWs with primary infections. In bivariate and multivariate analyses, the OR for HSV-2 IgG increased with age (OR=2.53-7.90, OR=2.66-6.37) and the number of sexual partners (OR=2.30-3.25). On the other hand, daily alcohol consumption (OR=0.10) and the use of condoms during the last intercourse (OR=0.47) were protective factors against HSV-2 acquisition.Conclusion: Despite the impact of FSWs in public health policies with the dissemination of sexually transmitted infections, there have been few studies performed regarding the prevalence of HSV-2 in Brazil, making it difficult to implement any control or preventative measures. The results produced here using an RDS methodology demonstrated a high prevalence, risk behaviours and primary infection among the FSWs. These results reinforce the need to implement control and preventative measures for HSV-2 infection in this population. [ABSTRACT FROM AUTHOR]

Abstract

A cross-sectional study on prevalence, associated factors and genotype distribution of HCV infection was conducted among 848 HIV-infected patients recruited at reference centers in the Midwest Region of Brazil. The prevalence rate of HIV-HCV coinfection was 6.9% (95% CI: 5.2 to 8.6). In multivariable analysis, increasing age, use of illicit drugs (injection and non-injection), a history of blood transfusion before 1994, and the absence of a steady partnership were significant independent associated factors for HIV-HCV coinfection. The phylogenetic analysis based on the NS5B region revealed the presence of two major circulating genotypes of HCV: genotypes 1 (58.3%) and 3 (41.7%). The prevalence of HIV-HCV coinfection was lower than those reported in studies conducted with HIV-infected patients in different regions of Brazil, due to the fact that illicit drug use is not a frequent mode of HIV transmission in this region of Brazil. Serologic screening of HIV-patients for HCV before initiating antiretroviral treatment, a comprehensive identification of associated factors, and the implementation of effective harm reduction programs are highly recommended to provide useful information for treatment and to prevent HCV coinfection in these patients. Estudo transversal sobre a prevalência, fatores associados e distribuição dos genótipos do HCV foi realizado em 848 pacientes infectados pelo HIV, recrutados em centros de referência na Região Centro-Oeste do Brasil. A taxa de prevalência de coinfecção HIV-HCV foi de 6,9% (IC 95%: 5,2-8,6). Na análise multivariada, o aumento da idade, o uso de drogas ilícitas (injetáveis e não injetáveis), história de transfusão de sangue antes de 1994, e ausência de companheiro constante foram fatores associados independentes e significativos para a coinfecção HIV-HCV. A análise filogenética baseada na região NS5B revelou a presença de dois principais genótipos do HCV em circulação: genótipos 1 (58,3%) e 3 (41,7%). A prevalência da coinfecção HIV-HCV foi menor do que as relatadas em estudos realizados com pacientes infectados pelo HIV em diferentes regiões do Brasil, devido ao fato de que o uso de drogas ilícitas não é modo frequente de transmissão do HIV neste Estado do Brasil. Triagem sorológica de pacientes HIV-positivos para HCV antes de iniciar o tratamento antirretroviral, identificação completa dos fatores associados e a implementação de programas eficazes de redução de danos são altamente recomendados para fornecer informações úteis, para o tratamento e para evitar a coinfecção com HCV nestes pacientes.

Abstract

Objectives:A cross-sectional study on prevalence of HBV and HDV infection, risk factors and genotype distribution of HBV infection was conducted among 848 HIV-infected patients in Mato Grosso do Sul, Central Brazil.Methods:Serum samples of 848 participants were tested for hepatitis B surface antigen (HBsAg), hepatitis B core antibody (anti-HBc) and hepatitis surface antibody (anti-HBs). HBsAg positive samples were tested for anti-HBc IgM, HBeAg, anti-HBe, anti-HCV, and total anti-HDV. HBsAg and anti-HBc positive were subjected to DNA extraction. Viral DNA was amplified by semi-nested PCR for the regions pre-S/S and then purified and genotyped/subgenotyped by direct sequencing. Student's t-test, chi-square test and Fisher's exact test were used to compare variables and to evaluate association between HBV positivity (defined as anti-HBc and/or HBsAg positivity) and risk factors.Results:Among the 848 HIV infected patients investigated 222 had serological markers of HBV infection. The prevalence rate of HIV-HBV coinfection was 2.5% (21/848; 95% CI: 1.4–3.5%); 484 (57.1%) patients were susceptible for HBV infection. There were no cases of anti-HDV positive and only one (0.1%) anti-HCV-positive case among the HIV-HBV coinfected patients. Male gender, increasing age, family history of hepatitis, use of illicit drug, and homosexual activity were independent factors associated with HBV exposure. The phylogenetic analysis based on the S gene region revealed the presence of genotypes D (76.9%), F (15.4%) and A (7.7%) in the study sample.Conclusion:This study demonstrates the low prevalence of HIV-HBV infection and also highlights the need for early vaccination against HBV as well as testing for HBV, HCV and HDV in all HIV-infected individuals.

Abstract

• Hard-to-reach populations remain, with a high exposure of HBV infection. • 63.7% of the participants were considered susceptible to HBV infection. • High risk of HBV infection due to living conditions and lack of information. • Low education level may neglect the importance of vaccines. • Accessible language can reduce the number of people susceptible to HBV infection. To evaluate the epidemiological and molecular features of HBV infection among recyclable waste collectors. The participants were recruited from the dumping ground and recycling cooperatives in Campo Grande, Brazil, and were screened for hepatitis B and C, and HIV serological markers by ELISA, confirmed by PCR. Among 278 participants, 63.7% (95% CI: 58.0–69.3) were considered susceptible to HBV infection. The prevalence rate of HBV exposure was 10.1% (95% CI: 6.5–13.6) and 0.4% (95% CI: 0.1–0.6) were chronic carriers. Age ≥45 years (AOR = 7.15), history of homosexual contact (AOR = 5.29), tattoo (AOR = 4.92) and history of surgery (AOR = 2.89) were factors associated with ever infection. Age 18–25 years (AOR = 4.63), educational level ≥9 years (AOR = 1.98) and knowledge about HBV transmission (AOR = 3.08) were associated with serological HBV vaccination like profile (26.2%; 95% CI: 21.1–31.4). Despite the availability and efficacy of HBV vaccine, this study found high HBV exposure and proportion of susceptible adults in a low endemic area. Vaccination and screening campaigns using accessible language to the economically disadvantaged populations can reduce the number of people susceptible to HBV infection. [ABSTRACT FROM AUTHOR]
