The Epidemic of Human Immunodeficiency Virus, Hepatitis C Virus, and Syphilis Infection, and the Correlates of Sexually Transmitted Infections among Men Who Have Sex with Men in Zhenjiang, Jiangsu, China

Human Immunodeficiency virus (HIV), Hepatitis B virus (HBV), Hepatitis C virus (HCV) and Syphilis infection are the major public health problem, alarming the most developing countries like Bangladesh. These studies determined the prevalence rate and risk factors of HIV, Hepatitis B, Hepatitis C and Syphilis among nonprofessional blood donors in multiple blood transfusion center of Chittagong. Information was collected by questionnaire to find out the relationship of HIV, HBV, HCV and Syphilis infection with age, sex, socioeconomic status, residence and religious believes. The sero-prevalence of HIV, HBsAg (HBV), anti-HCV (HCV), VDRL (Syphilis) among the non-professional blood donors were 00.00%, 4.88%, 0.92%, and 0.70% respectively. So, the highest prevalence rate was HBsAg and the lowest was HIV. We didnt find more than one positive case in the same blood sample. The prevalence of HBsAg among the study population, students (120/6) were 5.00%, service holders (73/3) were 4.11%, businessmen (40/4) were 10%, housewives (14/0) were 00.00%, others (farmers, immigrant workers) (40/1) were 2.50%. The highest prevalence of HBsAg was due to illiteracy and unsafe sexual behaviors.Asian J. Med. Biol. Res. December 2015, 1(3): 518-525

Introduction: Early diagnosis is a crucial tool for containing the human immunodeficiency virus and other sexually transmitted infections, particularly in key populations such as sex workers. Despite its relevance, there is a gap considering epidemiological studies and interventions aimed at the monitoring and diagnosis of sexually transmitted infections in Portugal. The objectives of this study are: (i) to contribute to a better understanding of the epidemiology of sexually transmitted infections; and (ii) to evaluate the transfer of screening methods from clinical settings to the outreach context in hidden populations such as sex workers.Material and Methods: The screening of sexually transmitted infections (human immunodeficiency virus 1/2, hepatitis B virus, hepatitis C virus, syphilis, chlamydia and gonorrhea) were carried out in a sample of 100 sex workers during the Porto G outreach intervention in the Metropolitan area of Porto, from September 2015 to September 2016.Results: Six reactive cases for human immunodeficiency virus were identified, five of syphilis, eight of chlamydia and two of gonorrhea. No positive results were detected for hepatitis B virus and hepatitis C virus. The results were discussed considering the risk gradient and sexually transmitted infections vulnerability in the different sex workers’ subgroups.Discussion: The results of this study corroborate the need to promote comprehensive responses to populations most affected by the human immunodeficiency virus and other sexually transmitted infections, such as sex workers. Also, in this group, men who have sex with men and trans women have a higher prevalence than cis women. Intervention strategies should be informed by rigorous epidemiological studies.Conclusion: The adaptation of the screening methodology performed in a clinical setting to the proximity context has shown to be an innovative response in Portugal, especially in sentinel populations.

Abstract Background. The epidemic of sexually transmitted hepatitis C virus (HCV) infection among human immunodeficiency virus (HIV)-infected men who have sex with men (MSM) has been documented for over a decade. Despite this, there is no consensus as to the risk factors for sexual acquisition of HCV in these men. Methods. We obtained paired semen and blood samples at 2-week intervals from HIV-infected MSM with recent and chronic HCV infection and quantified HCV in semen. Results. Hepatitis C virus was quantified in 59 semen specimens from 33 men. Hepatitis C virus was shed in 16 (27%) of semen specimens from 11 (33%) of the men. Median HCV viral load (VL) in semen was 1.49 log10 IU/mL. Hepatitis C virus VL in blood was significantly higher at the time of HCV shedding in semen than when HCV shedding in semen was not detected (P = .002). Furthermore, there was a significant correlation between the HCV VL in blood and semen overall (rs = 0.41; P = .001), and in the subgroup with recent HCV infection (rs = 0.37; P = .02), but not in the subgroup with chronic HCV infection (rs = 0.34; P = .1). Conclusions. One third of HIV-infected MSM coinfected with HCV shed HCV into their semen. Based on the HCV VL in semen in this study, an average ejaculate would deliver up to 6630 IU of virus into the rectum of the receptive partner. Therefore, our data strongly support that condoms should be used during anal intercourse among MSM to prevent transmission of HCV.
