Prevalence of HIV and syphilis and their co-infection among men having sex with men in Asia: A systematic review and meta-analysis. Heliyon 2023; 9:e13947. [PMID: 36895383 PMCID: PMC9988516 DOI: 10.1016/j.heliyon.2023.e13947] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2021] [Revised: 02/08/2023] [Accepted: 02/15/2023] [Indexed: 02/23/2023] Open
Abstract
Background Studies found that the group of men who have sex with men (MSM) is at a very high level of risk of HIV and sexually transmitted infections (STIs) in Asian regions due to multiple reasons. Although the prevalence of HIV among general people in Asia is considered low, the prevalence of HIV and Syphilis among MSM in this region was found very high and usually, it goes unnoticed. This study aimed to inspect the prevalence of and trends in HIV, Syphilis, and their co-infection among MSM in Asia. Methods A systematic search was performed on January 5, 2021, in PubMed, Web of Science, and Google Scholar databases. To evaluate the heterogeneity, Q-tests, and I 2 were used. To explore the publication bias, Eggers' test and funnel plot were used. The random-effect model and subgroup analysis were performed due to the significant heterogeneity. Results A total of 2872 articles were identified, and 66 articles were included in the final analysis. The overall prevalence of HIV and Syphilis among MSM was estimated considering 69 estimates from 66 studies whereas 19 estimates of co-infection were found in 17 studies. The pooled HIV prevalence was 8.48% (CI: 7.01-9.95) and the pooled Syphilis prevalence was 9.86% (CI: 8.30-11.41) with significant heterogeneity and publication bias. The pooled prevalence of HIV and Syphilis co-infection was 2.99% (CI: 1.70-4.27) with significant heterogeneity and no publication bias. The HIV, Syphilis, and HIV-Syphilis co-infection prevalence estimates exhibited an upward trend during 2002-2017. Conclusions HIV, Syphilis, and their co-infection are quite prevalent among MSM in the Asia-Pacific region. Integrated and intensified intervention strategies, HIV testing, and improved access to antiretroviral treatment as well as increased awareness are needed to reduce HIV, Syphilis, and their co-infection among the discussed vulnerable group.

Systematic Review of Hepatitis C Virus Prevalence in the WHO Western Pacific Region. Viruses 2022; 14:v14071548. [PMID: 35891529 PMCID: PMC9320901 DOI: 10.3390/v14071548] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2022] [Revised: 07/11/2022] [Accepted: 07/13/2022] [Indexed: 11/16/2022] Open
Abstract
BACKGROUND This review aimed to identify hepatitis C virus (HCV) prevalence estimates among the general population and six key populations (people who inject drugs, men who have sex with men, sex workers, prisoners/detainees, Indigenous people, and migrants) in the World Health Organization Western Pacific Region (WHO WPR). METHODS Original research articles published between 2016 and 2020 were identified from bibliographic databases. Publications were retrieved, replicas removed, and abstracts screened. Retained full texts were assessed and excluded if inclusion criteria were not met. Methodological quality was assessed using the Johanna Briggs Institute critical appraisal checklist for prevalence data. Data on HCV exposure and active infection were extracted and aggregated and forest plots generated for each population by country. RESULTS There were no HCV prevalence estimates in any population for more than half of WPR countries and territories. Among the 76 estimates, 97% presented prevalence of exposure and 33% prevalence of active infection. General population viraemic prevalence was 1% or less, except in Mongolia. Results confirm the endemic nature of HCV among people who inject drugs, with estimates of exposure ranging from 30% in Cambodia to 76% in Hong Kong. CONCLUSIONS Countries require detailed knowledge of HCV prevalence in diverse populations to evaluate the impact of efforts to support WHO HCV elimination goals. Results provide baseline estimates from which to monitor and evaluate progress and by which to benchmark future elimination efforts.

Prevalence and incidence of hepatitis C virus infection in men who have sex with men: a systematic review and meta-analysis. Lancet Gastroenterol Hepatol 2020; 6:39-56. [PMID: 33217341 DOI: 10.1016/s2468-1253(20)30303-4] [Citation(s) in RCA: 64] [Impact Index Per Article: 16.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/27/2020] [Revised: 09/07/2020] [Accepted: 09/08/2020] [Indexed: 12/14/2022]
Abstract
BACKGROUND WHO has set targets for hepatitis C virus (HCV) elimination by 2030. We did a global systematic review of HCV prevalence and incidence in men who have sex with men (MSM) to provide updated estimates that can guide community education and public health policy. METHODS We did a systematic review and meta-analysis of studies published and listed on MEDLINE or Embase between Jan 1, 2000, and Oct 31, 2019, including conference proceedings. Studies were eligible if they reported measures of HCV prevalence or HCV incidence (or both) among MSM. Studies that relied on participants' self-reported HCV status with no laboratory confirmation were excluded. Pooled HCV estimates in MSM were stratified by HIV status and by injecting drug use, then by WHO region and by income level. Random-effects meta-analysis was done to account for between-study heterogeneity and examined using the I2 statistic. Pooled HCV prevalence was also compared with HCV estimates in the general population and presented as prevalence ratios (PRs). In HIV-negative MSM, incidence estimates were stratified by use of HIV pre-exposure prophylaxis (PrEP). The systematic review was registered with PROSPERO, number CRD42020156262. FINDINGS Of 1221 publications identified, 194 were deemed to be eligible and included in the systematic review and meta-analysis. Overall, the pooled HCV prevalence in MSM was 3·4% (95% CI 2·8-4·0; I2=98·0%) and was highest in Africa (5·8%, 2·5-10·4) and South-East Asia (5·0%, 0·0-16·6). Globally, HCV prevalence was 1·5% (1·0-2·1) in HIV-negative MSM and 6·3% (5·3-7·5) in HIV-positive MSM. Compared with the general population, HCV prevalence was slightly higher in HIV-negative MSM (PR 1·58, 95% CI 1·14-2·01) and markedly higher (6·22, 5·14-7·29) in HIV-positive MSM. Pooled HCV prevalence was substantially higher in MSM who had ever injected drugs (30·2%, 22·0-39·0) or currently injected drugs (45·6%, 21·6-70·7) than in those who never injected drugs (2·7%, 2·0-3·6). In HIV-negative MSM, the pooled HCV incidence was 0·12 per 1000 person-years (95% CI 0·00-0·72) in individuals not on PrEP and 14·80 per 1000 person-years (9·65-20·95) in individuals on PrEP. HCV incidence in HIV-positive MSM was 8·46 per 1000 person-years (6·78-10·32). INTERPRETATION HIV-positive MSM are at substantially increased risk of HCV. Overall, HIV-negative MSM had a slightly higher prevalence of HCV than the general population but had a lower prevalence than HIV-positive MSM. High HCV incidence in more recent PrEP studies suggests that as PrEP use increases, greater HCV transmission might occur. HCV burden in MSM varies considerably by region, which is likely to be associated with variation in the prevalence of injecting drug use and HIV. FUNDING World Health Organization.

Abstract
Prevalence of co-infecting sexually transmitted infections (STIs) among patients newly diagnosed with anogenital warts is under-reported. Our objective is to determine the prevalence of six common STIs, Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), Mycoplasma genitalium (MG), genital herpes (herpes simplex virus type 2 [HSV-2]), HIV, and syphilis for patients visiting a sexual health clinic in Guangzhou, China. Demographics, sexual health, and medical histories were collected at patient intake. Patients diagnosed with anogenital warts (N = 200) were invited to participate. We collected urine samples, and urethral, cervical, and rectal swabs to test for CT, NG, and MG, and blood samples for serological detection of HSV-2, syphilis, and HIV. Overall 49 (24.5%) had a co-infection (22.2% of men and 27.7% of women). All six STIs were observed among men: CT (6.8%), NG (3.4%), MG (5.1%), HIV (4.3%), HSV-2 (4.3%), and syphilis (1.7%). Women had fewer STIs, but at higher rates: CT (13.3%), MG (6.0%), and HSV-2 (8.4%). Individual men had up to two co-infections, while women had no more than one co-infection. Chlamydia was the most common STI. Patients aged 18-25 years (35.4%) had the highest prevalence. Although opportunistic screening is often applied for high-risk groups, expansion to patients with anogenital warts in all health-care settings would improve detection of problematic asymptomatic co-infections, thereby increasing China's capacity to contribute toward global surveillance systems.

Trends of recent hepatitis C virus infection among HIV-positive men who have sex with men in Taiwan, 2011-2018. EClinicalMedicine 2020; 24:100441. [PMID: 32637905 PMCID: PMC7327892 DOI: 10.1016/j.eclinm.2020.100441] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/14/2020] [Revised: 06/08/2020] [Accepted: 06/11/2020] [Indexed: 01/14/2023] Open
Abstract
BACKGROUND Increasing trends of HCV infection have been reported among HIV-positive men who have sex with men (MSM) in Europe, Australia and North America. The trends of recently acquired HCV infection among HIV-positive MSM are less clear in Asia-pacific region. METHODS All HIV-positive patients seeking care at a university hospital in Taiwan tested for anti-HCV IgG at least once annually to estimate the incidence of HCV seroconversion during 2011-2018. HCV genotyping and sequencing were performed and multivariate logistic regression analysis was conducted to identify the factors associated with HCV seroconversion among MSM. FINDINGS During the study period, 3495 HCV-seronegative patients (86·4% MSM) were included and 294 (8·4%) with recent HCV infection were identified, in whom 281 (95·6%) were MSM, during a total of 16,361·86 person-years of follow-up (PYFU), giving an overall incidence rate of 17·97 per 1000 PYFU, which increased from 14·28 per 1000 PYFU in 2011 to 25·38 per 1000 PYFU in 2018 (p<0·001). HCV seroconversion among MSM was associated with aspartate aminotransferase ≥37 U/L (adjusted odds ratio [AOR] 7·50, 95% CI 4·17-13·50), alanine aminotransferase ≥41 U/L (AOR 7·47, 95% CI 4·11-13·58), and syphilis acquisition (AOR 2·88, 95% CI 1·67-4·97). Among the 277 (94·2%) with HCV viremia, genotype 2a (n = 116) was the leading genotype, followed by 1b (n = 85), 6a (n = 34), and 1a (n = 21). Genotypes 3a and 6a increased from 0% and 5·2%, respectively, in 2011-2014 to 4·1% and 17·1% in 2015-2018. Phylogenetic analysis revealed increased clusters in genotypes 2a, 3a and 6a from 2011-2014 to 2015-2018. INTERPRETATION An expanding HCV epidemic among HIV-positive MSM is occurring in Taiwan. Improving access to HCV testing and early linkage to treatment are needed to curb the expanding HCV epidemic. FUNDING This research was supported by a grant from National Taiwan University Hospital, Taipei, Taiwan (NTUH.106-003347 to Hsin-Yun Sun).

Abstract
PURPOSE OF REVIEW This review is intended to provide an overview of the evolution of HIV epidemiology over the past decade in China. RECENT FINDINGS We provided a succinct overall view of the epidemic, followed by surveillance data, profiles of key populations, HIV molecular epidemiology, and drug resistance, as well as survival in the age of antiretroviral therapy usage. For each topical issue, we first reviewed the latest empirical evidence, followed by a brief summary assessment. We briefly addressed the challenges and opportunities of the next generation of HIV control and prevention efforts in China. Notably, macro-social factors need to be integrated into the next generation of clinical and/or behavioral HIV research to inform disease progression and management, as well as control and prevention.

Abstract
BACKGROUND Acute hepatitis C virus (HCV) infections have been increasingly reported among human immunodeficiency virus (HIV)-positive men who have sex with men (MSM) in the Asia-Pacific region. It remains unknown whether international network of HCV transmission has occurred in this region. METHODS HIV-positive patients with acute HCV infection, defined as HCV seroconversion within a year or documented acute hepatitis with seroconversion, diagnosed in Hong Kong, Taipei and Tokyo during 2010-2016 were included in this molecular epidemiology study. The NS5B region of the HCV genome (365 bp) was amplified using nested polymerase chain reaction and sequenced. RESULTS Of 234 HIV-positive patients with acute HCV infection, all were male with 94% being MSM. At the diagnosis of acute HCV infection, 73.5% had concurrent sexually transmitted diseases and 88.0% were receiving combination antiretroviral therapy. The most prevalent HCV genotype was 3a, 2a and 1b in Hong Kong, Taipei and Tokyo respectively. Nine independent clusters belonging to five genotypes (1b, 2a, 2c, 3a and 6a) were identified, each of which occurred in one city without overlapping except for one 3a sequence from Taipei that was closely related genetically to the Hong Kong cluster. CONCLUSIONS No international network of HCV transmission was identified among HIV-positive patients in the three Asia-Pacific cities. The transmission dynamics of sexually acquired HCV differed by city, but the risk of intercity clustering should not be ignored.

Prevalence of Active Syphilis Infection and Risk Factors among HIV-Positive MSM in Zhejiang, China in 2015: A Cross-Sectional Study. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2019; 16:ijerph16091507. [PMID: 31035429 PMCID: PMC6539918 DOI: 10.3390/ijerph16091507] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 04/10/2019] [Revised: 04/22/2019] [Accepted: 04/23/2019] [Indexed: 01/09/2023]
Abstract
Objectives: To determine the prevalence of active syphilis infection and explore the risk factors for active syphilis in human immunodeficiency virus (HIV)-positive men who had sex with men (MSM) in Zhejiang Province, 2015. Design: Data on HIV-positive MSM living in Zhejiang Province were obtained from the National Center for AIDS/STD Control and Prevention (NCAIDS) reporting system and the Zhejiang provincial AIDS/STD surveillance system between June and December 2015. The information included risky behavior, years with diagnosed HIV, and highly active antiretroviral therapy (HAART). SPSS 19.0 was used for the data analysis. Results: The analysis included 3616 MSM. Of these, 11.3% (407/3616) had active syphilis. Multivariate logistic regression analysis revealed that HAART was significantly associated with an increased risk of active syphilis infection (odds ratio (OR) = 1.760, 95% confidence interval (CI) 1.187–2.611). Compared with participants diagnosed with HIV for <2 years, patients diagnosed with HIV for >5 years had a higher risk of active syphilis infection (OR = 1.707, 95% CI 1.167–2.495). Age and number of sex partners were also independent risk factors for active syphilis infection. Conclusions: The incidence of active syphilis infection is high among HIV-positive MSM in Zhejiang Province; age, number of sex partners, years with diagnosed HIV, and receiving HAART were risk factors. Patients who are elderly, have lived with HIV for a longer period, have more sex partners, and receive HAART should be the focus of interventions to promote changes in behavior and decrease syphilis infection.

Prevalence of HIV and syphilis co-infection and associated factors among non-commercial men who have sex with men attending a sexually transmitted disease clinic in Shenzhen, China. BMC Infect Dis 2017; 17:86. [PMID: 28100187 PMCID: PMC5241916 DOI: 10.1186/s12879-017-2187-1] [Citation(s) in RCA: 18] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2016] [Accepted: 01/05/2017] [Indexed: 11/26/2022] Open
Abstract
BACKGROUND Although HIV and syphilis co-infection has been frequently observed in men who have sex with men (MSM), only few studies have focused on it. Different subgroups of MSM might exhibit heterogeneous HIV and syphilis risk profiles, indicating that interventions for HIV and HIV-related co-infections may vary with different subgroups of MSM. However, no previous study has investigated HIV and syphilis co-infection among non-commercial MSM (ncMSM) attending a sexually transmitted disease (STD) clinic. Therefore, this study aimed to explore the prevalence of HIV and syphilis co-infection and associated factors among ncMSM attending an STD clinic in Shenzhen, China. METHODS NcMSM attending the STD clinic of Shenzhen Center for Chronic Disease Control were recruited in this cross-sectional study every Monday between March 2013 and August 2015 using a site based convenience sampling method. An anonymous questionnaire was used to collect data regarding socio-demographic characteristics, risky sexual behaviors and HIV-related knowledge. Blood samples were collected to perform HIV and syphilis tests. RESULTS Totally 533 participants were enrolled in this study and the prevalence of HIV and syphilis co-infection among them was 13.13%. Multivariable analyses indicated that having lived in Shenzhen for less than one year (aOR = 2.80, 95% CI = 1.30-6.05), having first anal sexual intercourse before the age of 18 (aOR = 2.78, 95% CI = 1.29-5.89), having 3 to 5 anal sexual partners in the past six months (aOR = 2.54, 95% CI = 1.19-5.40), playing exclusively receptive (aOR = 6.87, 95% CI = 3.02-15.61) or both insertive and receptive (aOR = 3.65, 95% CI = 1.64-8.09) roles in anal sexual intercourse and not always using condom in anal sexual intercourse (aOR = 2.13, 95% CI = 1.08-4.19) were associated risk factors for HIV and syphilis co-infection, relative to the non-infected ncMSM. Compared with the mono-infected ncMSM, associated risk factors for the co-infection were being unmarried (aOR = 2.47, 95% CI = 1.03-5.89) and playing exclusively receptive role (aOR = 2.44, 95% CI = 1.04-5.73) in anal sexual intercourse. CONCLUSIONS HIV and syphilis co-infection is quite prevalent among the study participants in Shenzhen. Integrated and intensified intervention strategies, specifically targeting at the non-infected and mono-infected ncMSM attending the STD clinic, are needed to reduce HIV and syphilis co-infection. Most importantly, non-infected and mono-infected ncMSM attending the STD clinic with the aforementioned associated risk factors should be given special concern.
